Abstract

The device for automatically raising fish traps, crayfish pots, nets and the like comprises a cylinder(19) of compressed gas connected through a control valve(20) to a buoyancy chamber provided with a discharge opening and adapted to be filled with water when the trap is submerged. The operation of the control valve is to allow gas to pass from the cylinder to the buoyancy chamber and expel water from th buoyancy chamber being effected through a timing mechanism or an electrical circuit activated by a signal transmitted through the water.

The present invention relates to an automatic flotation device such as a fish trap, a lobster port, a net, etc., and the term “capture hole” in the main text refers to the absence of a rope or the like.

To date, fishermen, especially lobster or lobster fishermen, have been working in relatively shallow water, not more than 200 feet deep.

Lobster catching in deep water requires heavy and long catch lines and takes more effort and time to lift catches to the surface.

In addition, when the catch is installed in shallow water, the catch connected to the catch line has a drawback to move the catch when a severe wave strikes.

It is an object of the present invention to provide an automatic flotation device for a fish catch that does not require an elongate salvage line and can reduce the time or effort required to lift the catch and move the catch therefrom.

The apparatus of the present invention consists of a compressed gas cylinder connected to an inlet having a discharge hole through a control valve, and the action of the control valve to supply gas from the cylinder to the inlet and discharge water from the inlet depends on a signal transmitted through the water. It is done via a running timer or electrical circuit.

The inlet chamber is fixed to the inside of the fixture and consists of a device that swells when gas is supplied, or a second cylinder that is mounted to the catch, and consists of one or more compartments in the member constituting the catch. May be

In particular, the wall of the catch is composed of a spiral plastic pressure-resistant pipe with one end connected to the gas cylinder and the other end opened.

Since the timer can operate the control valve after the scheduled time, the fishermen can approach the place where the catch is installed, recover the catch and move the catch.

Therefore, it is desirable to use a radio wave or acoustic signal to operate an electrical circuit to operate the stir valve. Radio waves do not penetrate the water, so it is better to use acoustic signals unless they are at very low frequencies and to use coded signals to prevent the device from being triggered accidentally.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In Figures 1, 2 and 3, the crayfish pots are provided with a flat bottom 11, a cylindrical wall 12 and a conventional shredded cone shape of plastic or other material. It is composed of spirally wound plastic pressure pipes long so that the diameter of 14 can be inserted so as to form the upper part 13 in the shape of a hemispherical shape. The spiral wound pressure-resistant pipe is fixed by a series of ribs 15 of metal or other suitable material. One end 16 of the pipe is located at the bottom of the catch and is open. The other end 17 is adjacent to the bent portion 14 and a tab 18 is inserted. The carbon dioxide cylinder 19 is inserted into the bottom of the port and is connected to the end 17 of the pressure-resistant pipe through the control device 20 and the pipe 21.

The control device 20 consists of a timer connected to the valve so that the valve opens after a predetermined time and gas is supplied from the cylinder to the pressure resistant pipe. The control device 20 consists of a circuit as shown in FIGS. 7 and 8, and is coupled to a decoder connected to a signal detector and a solenoid driver to operate the solenoid valve as described in detail below. It consists of. When the solenoid valve is opened, gas flows from the cylinder 19 past the pipe to the end 17 of the plastic pressure-resistant pipe.

The bait is installed in the port into which the carbon dioxide gas under pressure is filled in the cylinder 19, the hose is inserted into the end 16, and the tab 18 is opened to fill the pressure-resistant pipe with water.

When the pressure pipe is filled with water, the tap 18 is locked, the hose is removed and the pot is submerged. After the port has subsided, the fisherman returns and activates the signal generator to send the encoded sound signal underwater. The controller 20 receives this signal to open the solenoid valve. The gas discharged from the cylinder 19 causes water to be discharged from the pressure resistant pipe through the end 16. The port will float and float to the surface. Even when the port floats, excess gas is discharged through the open end 16. The pot is withdrawn and the catch is transferred. After the cylinder 19 is refilled or replaced with a new one, the bait is refilled and the pressure pipe is filled with water, the pot is submerged again.

4, 5 and 6, the catch port is a conventional slate type port, which is provided with two cylindrical sub chambers, each of which consists of a metal cylinder 31 and a hole 32 at each end. Each cylinder 31 is woven with a strong rubber bag 33, which is secured by a series of rubber bands 34 having fixed ends at the holes in the cylinder wall. The rubber band 34 functions to maintain the position of the rubber bag even when gas escapes from the rubber bag. The end portion of the rubber bag is connected to the gas cylinder 35 through a control device 36 similar to the control device 20 of the first embodiment. A pressure relief valve 37 and a manual valve 38 are installed in the gas line. The operation of this catch is similar to that of the first embodiment. The manual valve 38 is opened so that the gas in the rubber bag can be discharged to the outside by the rubber band 34 pressing the rubber bag. When the rubber bag 33 is completely flat, the valve 38 is closed, the gas cylinder 35 is refilled or replaced with a new one, and the bait is put in the port. As it is submerged in water, the cylinder 31 fills water through the hole 32. When the control device 36 is operated, gas is filled in the rubber bag and water is discharged from the cylinder 31. This creates buoyancy in the port, causing the port to float to the surface. When the port floats on the surface, the pressure relief valve 37 discharges excess gas to prevent the rubber bag 33 from popping out.

The signal receiver shown in FIG. 7 consists of a microphone or similar sound detector 41 in the detector 44 via amplifiers 42 and 43, and the detector 44 is provided with the decoder and solenoid driver shown in FIG. The signal supplied to the pulse width detector 45 is generated. The signal component passing through the detector 44 is supplied to a 12-bit shift register 48 connected to the decoder 49 via a reset timer 46 and a clock 47. The decoder output is supplied to the solenoid driver 53 which operates the solenoid valve (not shown) through the decoder time delay 50 and the output timer 51. In addition, the output timer 51 is connected to the reset timer 46 through the repetition suppression timer 52. The decoder is designed so that the solenoid driver does not operate on signals other than those generated by the signal generator. Although the same combination of signals, such as those generated by the signal generator, are detected by the detector, the control unit is not operated by the stray signal unless they are normally matched by analyzing the pulse width and the timing of the various signal components. . The code can be determined by changing the decoder matrix diameter.

Components such as signal receivers, decoders, solenoid drivers and solenoid valves should be embedded in a resinous reservoir, such as epoxy resin, to be waterproof in deep water. The battery, the power supply for the control unit, should be placed in a plastic case.

The present invention can also be used for fishing nets, in which a plastic pipe is circumscribed around the fishing net so that the pipe can be connected to the gas cylinder through the control device of the two embodiments mentioned above.

To make it easy to see where the catch is installed, a catch can be attached to one catch and a balloon filled with light gas, such as helium or hydrogen, can be suspended. A radio transmitter or lamp can be attached to the balloon so that the balloon can be found without difficulty. In addition, by forming a metal reflecting surface on the balloon can be easily located by the radar equipment installed on the vessel. In addition, a small radio transmitter may be installed in the catching sphere itself so that the position of the catching hole can be easily detected by the ship when the catching hole floats to the surface.
