For convenience, the following description will directly describe the water spray unit 12 having four water sprayers 121a-121d distributed in a ring shape, but the implementation manner is not To this end, for example, the number of sprinklers can be more, and the orientation can be set in other directions. In order to facilitate the clear presentation of the water spray channel measuring device 2 in FIG. 3, the views of FIGS. 3 and 4 are depicted based on the cutaway view in the II-II direction of FIG. 2, wherein only the left is displayed for each water spray unit 12. The right two sprinklers 121a and 121b (the front and rear sprinklers 121c and 121d are omitted). An embodiment of the water spray channel measuring device 2 of the present invention comprises a body 21 and a measuring unit 22 (shown in Figure 8).

Referring to FIG. 5 and FIG. 4, the seat body 21 is disposed at a head end 111 of the guide rod 11 of the small steel preform continuous casting apparatus, and a cross-sectional area of the seat body 21 is not greater than the guide roller set. An area of each of the passage openings 130 of 13 (such as the size of the passage opening 130 defined by the guide roller set 13 of FIG. 4) to follow the guide rod 11 through the passage openings 130 and through the respective spray units 12 The corresponding water spray interval 200.

Referring to FIG. 6 and FIG. 7, it is noted that the head end 111 of the guide rod 11 has a substantially arc-shaped contact surface 112 and an inner recess 113 below the contact surface 112. In the embodiment, the base body 21 includes a base 211 and a top seat 212. The side shape of the base 211 of the base body 21 is arc-shaped to match the curvature of the head end 111 of the guide rod 11. Completely joined. And the base 211 includes a fixed strong magnet 213 (FIG. 7) for adsorbing to the contact surface 112 of the guide rod 11, and a movable force for adsorbing to the surface of the inner groove 113 of the guide rod 11. Magnet 214. The stationary strong magnet 213 and the movable powerful magnet 214 are each a neodymium iron boron magnet. In addition, the top seat 212 of the base body 21 has a rectangular parallelepiped shape and can be screwed to the base 211 of the base body 21, for example.

Referring to FIG. 8 and FIG. 9, the measuring unit 22 is disposed on the top seat 212 of the seat body 21 to follow the top seat 212, and for the four water sprinklers 121a-121d of each of the water spray units 12, Four water spray lines are measured sequentially and in real time, and the measured four water spray lines are converted into four measured values respectively proportional to the water spray lines. In a first embodiment of the measuring unit 22, the measuring unit 22 includes four water spray sensors 221a to 221d (only one water spray sensor 221c is depicted in FIG. 8), and four correction sensors. 222a~222d, and a signal processor 223. The four water spray sensors 221a to 221d are disposed on the outer peripheral surface of the top seat 212 of the base body 21, and in the embodiment, the four water spray sensors 221a to 221d are respectively disposed on the top seat 212. The front, rear, left, and right sides form an annular sensing array, and for each of the four water sprinklers 121a-121d of each water spraying unit 12, each of the water spray sensors 221a to 221d is subjected to a position corresponding to the position thereof. The water spraying paths of the water sprinklers 121a to 121d generate and output the first sensing signals S1 to S4 corresponding to the water spraying directions of the water sprinklers 121a to 121d at the positions thereof, and are carried by each of the first sensing signals S1 to S4. The value is related to a water jet force value of the corresponding sprinklers 121a to 121d and a gravity value that changes in accordance with the movement of the guide rod 11.

Referring to FIG. 10 and FIG. 9, each of the water spray sensors 221a-221d includes a first force receiving plate 224a-224d and a first strain gauge 225a-225d. The first force receiving plates 224a to 224d are for receiving the water spraying force of the water sprinklers 121a to 121d corresponding to their positions (i.e., front/rear/left/right) and the gravitational force which changes in accordance with the movement of the guide bar 11. The first strain gauges 225a-225d are configured to receive the pressure applied by the first force receiving plates 224a-224d due to the water spray force and the gravity that changes following the movement of the guide rod 11, thereby deforming itself and changing the resistance value. Further, the first sensing signals S1 to S4 carrying the water jet force value and the gravity value corresponding to the position where they are located are generated and output.

Referring to FIG. 11 and FIG. 9, the correction sensors 222a-222d are disposed in the top seat 212 of the base 21 and correspond to the water spray sensing positions of the respective front/rear/left/right positions. Each of the correction sensors 222a-222d is configured to sense a gravity value that changes according to the movement of the guide rod 11 to generate and output a second sensing signal S1' related to the gravity value. S4'. In detail, each of the correction sensors 222a-222d includes a second force-receiving plate 226a-226d and a second strain gauge 227a-227d. The second force receiving plates 226a to 226d are configured to withstand the gravity which changes according to the movement of the guiding rod 11. The second strain gauges 227a to 227d are changed by the second force receiving plates 226a to 226d following the movement of the guiding rod 11. The gravity acts to deform itself and change the resistance value, thereby generating and outputting the second sensing signals S1'~S4' carrying the gravity values corresponding to their positions.

Referring to FIG. 12, similarly, when the first (or second) force plates 224a to 224d (or 226a to 226d) are in the vertical direction, the first (or second) strain gauges 225a to 225d (or 227a~) 227d) is almost unstressed, for example, its current reading can be zeroed. Then, when the first (or second) strain gauges 225a to 225d (or 227a to 227d) are changed from vertical to horizontal, the first (or second) force plates 224a to 224d (or 226a to 226d) The force of the first (or second) strain gauges 225a to 225d (or 227a to 227d) may change, causing the first (or second) strain gauges 225a to 225d (or 227a to 227d) to be deformed. The resistance value is changed, so the reading will be different compared to the vertical direction. That is to say, for example, in the case of the water spray sensors 221a to 221d, in the process of following the movement of the guide rod 11, when it is first subjected to a water spray external force in the vertical direction, then it is converted to the horizontal direction. When the external action of the water spray is applied, the reading values of the first strain gauges 225a to 225d will be different, and thus an error will occur. Therefore, the present invention provides the correction sensors 222a to 222d at positions corresponding to the water spray sensors 221a to 221d in the top seat 212 so as to correspond to the water spray sensors 221a corresponding to the positions. The 221d is synchronously subjected to gravity, and can be easily corrected later.

Referring to FIG. 13, it is to be noted that when the first (or second) force receiving plates 224a to 224d (or 226a to 226d) are in the horizontal direction, only the gravity in the vertical direction is applied. For example, its current reading can be zeroed. Then, when the first (or second) strain gauges 225a to 225d (or 227a to 227d) are inclined at an angle instead of being horizontal, the first (or second) force plates 224a to 224d (or 226a~226d) itself will change the force of the first (or second) strain gauges 225a~225d (or 227a~227d), resulting in the first (or second) strain gauges 225a~225d (or 227a~227d) The deformation occurs and the resistance value is changed, so the reading value will be different from the horizontal direction. That is to say, for example, in the case of the water spray sensors 221a to 221d, in the process of following the movement of the guide rod 11, when it is first subjected to the external action of the water spray in the horizontal direction, and then the angle is inclined by the external force of the water spray. At this time, the reading values of the first strain gauges 225a to 225d will be different, and thus an error will occur. Therefore, the present invention provides the correction sensors 222a to 222d at positions corresponding to the water spray sensors 221a to 221d in the top seat 212 so as to correspond to the water spray sensors 221a corresponding to the positions. ~221d is synchronously subjected to gravity, which can be easily corrected later.

Referring to FIG. 14 and FIG. 9, the signal processor 223 is electrically connected to the water spray sensors 221a-221d and the correction sensors 222a-222d to receive the output of the water spray sensors 221a-221d. a sensing signal S1~S4 and second sensing signals S1'~S4' output by the correction sensors 222a-222d, and for each of the four water sprinklers 121a-121d of each water spraying unit 12, the signal processing The controller 223 calculates the first sensing signals S1 S S4 output by the corresponding water spray sensors 221 a - 221 d and the second sensing signals S1 ' to S 4 ' output by the correcting sensors 222 a - 222 d . The measured values of the water spray lines of the four water sprinklers 121a to 121d corresponding to the water spray unit 12 are output.

In detail, the signal processor 223 includes a multi-channel synchronous sampling analog/digital conversion module 231, a processing module 232, a storage module 233, and a wireless communication module 234.

The analog/digital conversion module 231 is electrically connected to the water spray sensors 221a - 221d and the correction sensors 222a - 222d for receiving the four water sprayers 121a - 121d of each water spray unit 12 The first sensing signals S1~S4 output by the water spray sensors 221a-221d are converted into four first sensing values, and the corresponding output of the correction sensors 222a-222d corresponding to the receiving positions The two sensing signals S1'~S4' are converted into four corresponding second sensing values. The analog/digital conversion module 231 has a function of synchronous sampling, and can output, for example, the four first sensing values and the four second sensing values in the form of a sequence of signals.

The processing module 232 is electrically connected to the analog/digital conversion module 231 to receive the first sensing values and the corresponding second sensing values, and subtract each corresponding sensing value from the corresponding first The two sensed values are calculated and outputted as four measured values of the water spray lines corresponding to the four water sprinklers 121a to 121d of the respective water spray units 12.

Referring to FIG. 15 and FIG. 16, the CH shown in FIG. 15 and FIG. 16 is the result of the first/second sensing value/measurement value, and the others are updated, set scale, Reset (Reset), and calibration (Calibration) and other functions. For example, for the water spray sensors 221a to 221d that are not subjected to external water spray, FIG. 15(a) shows that the water spray sensors 221a to 221d that are not subjected to the external water spray force are vertically grounded and corrected to zero. The first sensing value received by the module 2232 (ie, the value displayed by CH1~CH4), and FIG. 15(b) shows that the water sensing sensors 221a-221d are inclined by 45 degrees, and the processing module 2232 receives The first sensed values obtained (ie, the values displayed by CH1~CH4). After the water spray sensors 221a to 221d are changed from the vertical ground direction to the tilt 45 degrees, the first sensed values (i.e., the values displayed by CH1 to CH4) generate a large error. However, as shown in FIG. 16, the processing module 2232 subtracts each of the received first sensing values (not shown) from its corresponding second sensing value (ie, the value displayed by CH5~CH8). Thereafter, the obtained measured values (that is, the values displayed by CH1 to CH4) can be maintained within -1g to +1g, and thus, the water spray sensor 221a is obtained regardless of the tilt angle. The measured value can eliminate the influence of gravity change, and the accuracy of the measured value can be significantly improved.

Referring to FIG. 14 , the storage module 233 is electrically connected to the processing module 232 to receive the measured value from the processing module 232 and store the same. The storage module 233 can be, for example, a flash memory, an electronic erasable rewritable read only memory (EEPROM), a secure digital (SD) memory card, or the like.

The wireless communication module 234 is electrically connected to the processing module 232 to receive the measured value from the processing module 232 and wirelessly transmit. The wireless communication module 234 is, for example, one of a WiFi module, a Bluetooth module, and a Zigbee module. The measurement value from the processing module 232 can be sent to the user's computer through, for example, an antenna, so that the user can immediately monitor the water spray lines of all the water spray units 12. In this way, for example, the monitoring personnel of the small-steel continuous casting equipment can instantly know the sprinklers of the water spray units 12 through the measured values of the water spraying force of the water spray unit 12 of each water spray section 200 displayed on the computer. 121a~121d is blocked or there is a situation in which the water spray is weakened for subsequent maintenance work.

It should be further noted that, during the movement of the guiding rod 11, the processing module 232 of the measuring unit 22 will sequentially measure the measured values of the water spraying force of the plurality of different water spraying units 12. Therefore, the processing module 232 can also add a time stamp to the measured values of the water spray force of each water spray unit 12, so as to be distinguished according to the chronological order. Which of the different water spray units 12 is the water spray force.

Referring to FIG. 17, in a second embodiment of the measuring unit 22, each of the front, rear, left, and right four faces of the outer peripheral surface of the top seat 212 of the base body 21 is correspondingly disposed. At least two of the water spray sensors, and in this embodiment, each of the front, rear, left, and right four faces of the outer peripheral surface of the top seat 212 is correspondingly provided with a plurality of water spray sensors. For example, FIG. 17 shows that the water spray sensors 221e-221g and the correction sensors 222e-222g are added to the rear of the top cover 212, and the water spray sensors 221e-221g can generate and output the water spray sensors 221e-221g. The first sensing signals S41-S43, the correction sensors 222e-222g can generate and output the second sensing signals S41'-S43', and thus can be, for example, in the water sprayer 121d of the water-spraying unit 12. The nozzle is partially blocked, and for example, the water spray sensor 221g does not measure the water spray force. Since the other water spray sensors 221f and 221g are added, the probability of detecting the water spray force can be increased.

In summary, the water spray channel measuring device 2 of the present invention has the following advantages.

1. Easy to install: The water spray channel measuring device 2 of the present invention has the seat body 21 of the compact size, and the fixed strong magnet 213 and the movable strong magnet 214 of the base 211 of the base body 21 are adsorbed to the guide rod. 11. The measuring unit 22 can follow the guiding port 11 defined by the guiding rod 11 and the seat body 21, and can pass through the water spraying section 100 where the water spraying units 12 are located.

2. Instantly measuring the water spray force: the measuring unit 22 of the water spray channel measuring device 2 of the present invention can transmit the analog/digital conversion of the measuring unit 22 for the four water sprinklers 121a to 121d of each water spraying unit 12 The module 231, the first sensing signals S1~S4 and the corresponding second sensing signals S1'~S4 measured by the corresponding water detecting sensors 221a-221d and the correcting sensors 222a-222d And converting to the first sensing value and the corresponding second sensing value, and subtracting the two by the processing module 232 to eliminate the movement process of the first strain gauge 225a-225d with the guiding rod 11 In the influence of the gravity change, the wireless communication module 234 wirelessly transmits the calculated measured values of the four water spray channels associated with each of the water spray units 12, so that the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the simple equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still Within the scope of the invention patent.
