The upward movement of the connection ring 230 drives the second push rod 250 to move upward, and drives the second push rod 250 to slide along the second connection rod 132 toward the connection column 160.
In this embodiment, as shown in fig. 1, the water source gradient sampling device for a deep water riverbed further includes a water reservoir 180, the water reservoir 180 is fixedly disposed on the supporting plate 110, an outlet end of the water pump 170 is disposed above the water reservoir 180, a water drainage groove is formed in a side wall of the water reservoir 180 in a penetrating manner, and the water drainage groove is disposed in a downward inclined manner. When water is pumped through the water pumping pipe 130, residual wastewater in the water pumping pipe 130 needs to be pumped out, the wastewater is sent into the water storage tank 180 and is slowly discharged through the water discharge groove, and the wastewater is prevented from being rapidly discharged into a water area to cause layered water body mixing, so that the purity of the extracted water sample is ensured.
In this embodiment, as shown in fig. 1, the gradient water source sampling device for a deep water riverbed further includes a connection block 190, the connection block 190 is fixedly sleeved on the connection column 160, and the water inlet end of the water pump 170 is disposed on the connection block 190. The connection block 190 blocks the pumping tube 130, and the connection block 190 does not rotate when the pumping tube 130 rotates.
The working process is as follows: in the initial state, the second push rod 250 is located at one end of the third link 231 far away from the connecting column 160. The shutter 210 is in an open state at this time because the upper surface of the shutter 210 abuts against the second push rod 250. The lower end of the support column 120 is fixed at the bottom end of the water sample.
According to the required sampling depth, the external motor is started, and the external motor drives the first gear 151 to rotate and drives the second gear 152 and the water pumping pipe 130 to rotate. When the first push rod 161 at the required sampling depth rotates to contact with the corresponding first link, the first link is pushed by the first push rod 161 to move towards the direction away from the connecting column 160, so as to drive the block to move, and further, the gap between the block and the water inlet pipe 131 is opened, so that water can enter the water pumping pipe 130. Meanwhile, the third push rod 232 contacts the stopper 163, and the third push rod 232 is pushed by the stopper 163 to move upwards and drives the connection ring 230 to move upwards. The second push rod 250 is slidably sleeved on the third link 231 through the first through hole. The upward movement of the connection ring 230 drives the second push rod 250 to move upward, and drives the second push rod 250 to slide along the second connection rod 132 toward the connection column 160. At this time, the second push rod 250 has no pressure on the baffles 210, and the baffles 210 are closed under the action of the spiral spring, so that the rubber blocks on the baffles 210 are abutted against the outer circumferential wall of the connecting column 160. At this time, the water pump 170 is controlled to start pumping water at the upper layer of the water pumping pipe 130, water with the required sampling depth enters from the water inlet pipe 131, and when a certain amount of water is pumped and all water samples above the baffle 210 are water samples at the position, a certain amount of sampling can be performed.
After sampling is finished, the water pumping pipe 130 is rotated, so that when the first connecting rod is separated from the first ejector rod 161, the blocking block is reset under the action of the pressure spring, and the water inlet pipe 131 is blocked again. When the third push rod 232 is out of contact with the stopper 163, the second push rod 250 moves downward to be reset under the action of the spring, and the connection ring 230 moves downward to be reset under the action of the self-gravity and the second push rod 250.
On one hand, the water flow generated by the rotation of the pumping pipe 130 can clean the filter screen 140, and on the other hand, the baffle 210 generates a certain stirring effect on the water flow generated by the rotation of the spiral spring, so that the filter screen 140 can be cleaned.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
