Example one

As shown in fig. 1, 2 and 3, the present embodiment provides a fish pumping machine, which includes a water pumping device, a water pumping pipe 2 and a water discharging pipe 3, wherein a water inlet end and a water outlet end of the water pumping device are respectively communicated with the water pumping pipe 2 and the water discharging pipe 3, and the communication mode is interference fit or connected through an anchor ear. One side of the water pumping device, which is close to the water pumping pipe 2, is provided with a circuit structure capable of generating weak current. The specific structure of the circuit structure for generating weak current is well known to those skilled in the art, and may be, for example, a structure in which a standard voltage is applied across a standard high-resistance resistor to generate weak current. One end of the water pumping device close to the water discharge pipe 3 is provided with a counting structure. Specifically, the counting structure in this embodiment is an infrared counter 5, and the portion of the water discharge pipe close to the infrared counter 5 is a transparent section 4. The water pumping device comprises a supporting seat 23, a first motor 25, fan blades 27 and a circular ring 24, a communicating cavity is arranged in the middle of the supporting seat 23, the circular ring 24 is arranged in a hollow mode, the circular ring 24 is communicated with the communicating cavity, a plurality of air outlets are evenly formed in the inner side of the circular ring 24, the first motor 25 is located in the communicating cavity, an output shaft of the first motor 25 is fixedly connected with the fan blades 27, and a plurality of air inlet holes 26 communicated with the communicating cavity are formed in the lower portion of the supporting seat 23. The infrared counter 5 in this embodiment may be an infrared counter of model DHC 11J.

The specific implementation process is as follows: in the scheme, when fish is pumped, the water pumping device is started, water in the original pond can be pumped into a new pond (or other containers) after the water pumping device is started, and the fish can also be pumped into the new pond along with the water. During the extraction process, the infrared counter can count the extracted fish, so as to know the number of the extracted fish. And a circuit structure capable of generating weak current is arranged on one side of the water pumping device close to the water pumping pipe 2, so that the fish can be ensured to always face to one direction when flowing in water.

Because pumping device includes supporting seat 23, first motor 25, flabellum 27 ring 24, start first motor 25 when starting pumping device earlier, first motor 25 rotates and drives flabellum 27 and rotate, outside air gets into the intercommunication intracavity from the inlet port 26 and enters into the air outlet discharge through ring 24 after ring 24 from the intercommunication chamber, the velocity of flow of the air of ring 24 exhaust is very fast, according to bernoulli's equation, thereby ring 24 center department produces the negative pressure and can remove the water in drinking-water pipe 2 to the discharge pipe, so when taking out the fish not the fry need not pass through the flabellum, can avoid fish to be injured.

Example two

As shown in fig. 4 and fig. 5, the difference between the first embodiment and the second embodiment is that the water pumping device 1 in the present embodiment includes a pump body 6, a piston 9, a water inlet 7, a water outlet 8, and a power source, a one-way water inlet valve and a one-way water outlet valve are respectively disposed at the water inlet 7 and the water outlet 8, a pump cavity is disposed in the pump body 6, the piston 9 is located in the pump cavity and is in sealed sliding connection with the pump cavity, the power source drives the piston 9 to slide, and the water pumping pipe 2 and the water discharging pipe 3 are respectively communicated with the water inlet 7 and the water outlet 8. Specifically, the power supply includes second motor 12, crank 11 and connecting rod 10, and second motor 12 output shaft is connected with crank 11 one end, and the crank 11 other end is connected with connecting rod 10 one end, and the connecting rod 10 other end is articulated with sliding block 14.

The specific implementation process is as follows: in the scheme, when the fish is pumped, the water pumping device is started, and water in the original pond can be pumped into a new pond (or other containers) after the water pumping device is started. And the fish will also be pumped with the water to a new pond. The starting mode of the water pumping device is as follows: the second motor 12 is started, and the second motor 12 rotates and drives the crank 11 to rotate. Because one end of the crank 11 is hinged with the connecting rod 13, and the other end of the connecting rod 13 is hinged with the piston 9, the second motor 12 rotates to drive the piston 9 to horizontally slide back and forth under the action of the crank 11 and the connecting rod 10, so that the volume formed by the piston 9 and the pump cavity in the pump cavity is continuously changed. When the volume in the pump cavity is increased, the air pressure in the pump cavity is reduced and suction force is generated, at the moment, the one-way water inlet valve is opened, the one-way water outlet valve is closed, and water and fish enter the pump cavity. When the volume of the pump cavity is reduced by the movement of the piston 9, the pressure in the pump cavity is increased, the one-way water inlet valve is closed, the one-way water outlet valve is opened, and the water and the fish in the pump cavity are discharged through the water outlet 8 and are discharged to a place needing to be discharged through the water discharge pipe.

By adopting the water pumping device in the embodiment, when fish is pumped, the fry is not necessarily contacted with the one-way water inlet valve or the one-way water outlet valve, and compared with an impeller pump, the damage to the fry can also be reduced.

EXAMPLE III

As shown in fig. 6, the present embodiment is different from the first embodiment in that an oxygen supply structure is provided at a side portion of the pump body in the present embodiment. The oxygen supply structure comprises an elastic corrugated pipe 16 and an oxygen supply pipe (not shown in the figure), two ends of the elastic corrugated pipe 16 are sealed, one end of the elastic corrugated pipe is provided with an air inlet, the other end of the elastic corrugated pipe is provided with an air outlet, the air inlet is provided with a one-way air inlet valve, and the air outlet is provided with a one-way air outlet valve. The oxygen supply structure in this embodiment further includes a pressing structure that presses the elastic bellows 16. The extrusion structure comprises a connecting frame 15 and an extrusion rod 17, and the elastic corrugated pipe 16 is fixedly connected with the connecting frame 15. The lower end of the extrusion rod 17 is an extrusion section 19, and the longitudinal section of the extrusion section 19 is triangular. The extrusion part comprises a sliding block 14 and a connecting rod 13, the sliding block 14 is horizontally and slidably connected with a connecting frame 15, two ends of the connecting rod 13 are respectively connected with the piston 9 and the sliding block 14, and the sliding block 14 is hinged with the end part of the connecting rod.

When fish needs to be taken out, the second motor 12 is started, and the second motor 12 rotates and drives the crank 11 to rotate. Since one end of crank 11 is hinged to the connecting rod and the other end of the connecting rod is hinged to the sliding block, the rotation of second motor 12 will drive sliding block 14 to slide horizontally and reciprocally through the action of crank 11 and connecting rod 10. Since the slide block 14 is connected to the piston 9 via the connecting rod 13, the piston 9 also reciprocates in the cylinder when the second motor 12 rotates. When the sliding block 14 slides horizontally, the sliding block can be in contact with the extrusion section 19 of the extrusion rod, because the lower end surface of the extrusion section 19 is triangular and the extrusion rod is vertically and slidably connected with the connecting frame 15, when the sliding block 14 slides, a force can be applied to the extrusion rod to enable the extrusion rod to slide upwards and extrude the elastic corrugated pipe 16, and air in the elastic corrugated pipe 16 is discharged through the one-way air outlet valve and enters the pump cavity, so that fish in the pump cavity can obtain enough oxygen. As the sliding block 14 continues to slide, it no longer contacts the rod, and the resilient bellows 16 returns to its original shape and pushes the rod to slide downward. In the process of restoring the elastic bellows 16 to its original shape, the external air enters the elastic bellows 16 through the one-way intake valve.

Example four

As shown in fig. 7, the present embodiment is different from the second embodiment in that the present embodiment further includes a connection plate 20. The connecting frame 15 is provided with a vertical sliding chute 18, and the connecting plate 20 is vertically and slidably connected with the connecting frame 15 through the sliding chute 18. The connecting plate 20 is provided with two horizontal sliding grooves 21, the number of the sliding grooves 21 is two, the extrusion rod is welded with two bulges 22, and the two bulges 22 are respectively positioned in the two sliding grooves 18. A spring is also provided between the connecting frame 15 and the connecting plate 20.

When the sliding block 14 slides to the right, the sliding block contacts with the squeezing rod, and the squeezing rod moves upwards under the action of the sliding block 14 and squeezes the elastic bellows 16, so that the air in the elastic bellows 16 enters the pump cavity. When the sliding block 14 slides leftwards, the sliding block 14 contacts with the extrusion rod again, at this time, the extrusion rod slides leftwards along the sliding groove 21 first, then slides rightwards along the extrusion rod, until the extrusion rod slides to the left end of the sliding groove 21, the connection plate 20 is driven to slide upwards, at this time, the extrusion rod is staggered with the elastic corrugated pipe 16, and the extrusion rod slides upwards, so that the elastic corrugated pipe 16 cannot be extruded. When the sliding block 14 slides, the connecting plate 20 slides downwards to the initial position under the action of the elastic spring. When the sliding block 14 slides to the right again, the sliding block 14 first drives the extrusion rod to slide to the right end of the sliding groove 21, and then pushes the extrusion rod to drive the connecting plate 20 to slide upwards.
