Description

Technical Field

[0001] This utility model relates to the field of fish fry and fish egg trapping and collection devices, specifically a fish fry and fish egg trapping and collection device. Background Technology

[0002] Artificially bred fish fry are the main source of aquaculture seedlings. Daily management of fry cultivation mainly includes feeding, waste removal, water quality maintenance, disinfection, and transferring the fry to different ponds. Among these, regular screening and transferring of fry to different ponds is a crucial step in fry cultivation. Meticulous and standardized transfer procedures not only improve the fry's resistance to disease but also significantly optimize the water quality environment during fry cultivation. The main human operation involved in the transfer process is the harvesting of the fry.

[0003] In the prior art, such as in CN212437000U, a fish fry and egg trapping and collection device is disclosed. This device includes a fish fry and egg trapping device and a fish-water separation device connected thereto. The fish fry and egg trapping device includes a fish fry trapping funnel, a steel wire hose, and a debris isolation net. The debris isolation net is placed on top of the fish fry trapping funnel and connected to it. An LED is installed on the fish fry trapping funnel. The LED is electrically connected to a stepless speed control button. The fish-water separation device includes a housing. A fish-water inlet and a drain outlet are arranged on the housing from front to back. A first fish-water separation platform and a second fish-water separation platform are arranged inside the housing from top to bottom. Fish collection buckets are respectively installed at the ends of the first and second fish-water separation platforms. The fish fry trapping funnel is connected to the drain outlet via the steel wire hose, the fish-water inlet, the first fish-water separation platform, and the second fish-water separation platform. This invention provides a fish fry and egg trapping and collection device that facilitates fish fry trapping and has a good fish-water separation effect.

[0004] Although the aforementioned patent facilitates the separation of fish and water through a fish-water separation platform, it lacks a structure to seal the fish inlet, making it unable to effectively prevent fish fry from escaping from the inlet. Furthermore, the fish-water separation structure is relatively complex and not convenient to operate. Therefore, a fish fry and egg trapping and collection device is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as the lack of a structure to seal the fish inlet, which makes it difficult to effectively prevent fish fry from escaping from the inlet; and the relatively complex structure for separating fish and water, which is not convenient to operate, this utility model proposes a fish fry and egg trapping and collection device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The fish fry and fish egg trapping and collection device of this utility model includes a conical groove, a connecting plate fixedly connected to the bottom surface of the conical groove, a guide groove fixedly connected to the bottom surface of the connecting plate, a guide pipe connected through the bottom end of the guide groove, a collection component connected through one end of the guide pipe, and a sponge block fixedly connected to one side of the conical groove by a connecting rod.

[0007] The collection assembly includes a solenoid valve that is connected to one end of a guide pipe. One end of the solenoid valve is connected to a collection box. The top of the collection box has a water outlet. A mesh screen is fixedly connected to the surface of the water outlet. A pumping pipe is fixedly connected to the top of the mesh screen. A water pump is fixedly connected to the top of the pumping pipe. A magnetic ring is fixedly connected to the bottom of the collection box. A screen is magnetically connected to the bottom of the magnetic ring. An observation port is provided on the side of the collection box. An observation window is fixedly connected to the surface of the observation port.

[0008] Preferably, a bracket is fixedly connected to the inner sidewall of the conical groove, a light strip is fixedly connected to the surface of the bracket, and a sealing box is fixedly connected to the top surface of the light strip.

[0009] Preferably, a mounting rod is fixedly connected symmetrically to one side of the conical groove, and the mounting rod has several mounting holes on its surface.

[0010] Preferably, the conical groove has a cavity on its back side with a built-in control board.

[0011] Preferably, the screen is detachably installed on the bottom surface of the magnetic ring via a magnetic connection.

[0012] Preferably, the control board is configured to intermittently control the opening and closing of the solenoid valve and regulate the operating status of the water pump.

[0013] The advantages of this utility model are:

[0014] 1. This utility model uses the intermittent opening and closing of the solenoid valve of the collection component and the control board to form a dynamic closed structure at the connection between the guide pipe and the collection box, which effectively prevents the fish fry from escaping in the reverse direction through the guide pipe. At the same time, the intermittent pumping of water reduces the adsorption time of the fish fry at the mesh, avoids damage caused by the fish fry being trapped by negative pressure, and improves the survival rate.

[0015] 2. This utility model achieves quick separation of fish fry from water at the screen by using a detachable magnetic connection between the magnetic ring and the screen, directly when the collection box leaves the water surface. Combined with the observation window to monitor the amount of fish fry collected in real time, it significantly simplifies the traditional fish-water separation operation process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-4 As shown, a fish fry and egg trapping and collection device includes a conical trough 1, a connecting plate 2 fixedly connected to the bottom surface of the conical trough 1, a guide trough 3 fixedly connected to the bottom surface of the connecting plate 2, a guide pipe 4 connected through the bottom end of the guide trough 3, a collection component 5 connected through one end of the guide pipe 4, and a sponge block 7 fixedly connected to one side of the conical trough 1 via a connecting rod 6; the collection component 5 includes a solenoid valve 51 connected through one end of the guide pipe 4, a collection box 52 connected through one end of the solenoid valve 51, a water outlet opened at the top of the collection box 52, a partition net 53 fixedly connected to the surface of the water outlet, a pumping pipe 54 fixedly connected to the top of the partition net 53, and a water pump 55 fixedly connected to the top of the pumping pipe 54.

[0024] During operation, the solenoid valve 51 is controlled by the control plate 12 in the cavity on the back of the conical groove 1. The solenoid valve 51 is opened and closed intermittently through a preset program, and the pumping frequency of the water pump 55 is adjusted in conjunction with it, so that a negative pressure water flow is periodically formed in the conical groove 1. The fish fry attracted by the light strip 9 are sucked into the collection box 52 through the guide channel 3 and the guide pipe 4. When the solenoid valve 51 is closed, the channel between the guide pipe 4 and the collection box 52 is cut off, preventing the fish fry from flowing back and escaping. At the same time, the water pump 55 is briefly stopped, which can reduce the adsorption time of the fish fry at the partition net 53 and avoid damage caused by the fish fry sticking to the partition net 53 due to continuous negative pressure.

[0025] Furthermore, a magnetic ring 56 is fixedly connected to the bottom surface of the collection box 52, and a screen 57 is magnetically connected to the bottom surface of the magnetic ring 56. An observation port is opened on the side of the collection box 52, and an observation window 58 is fixedly connected to the surface of the observation port.

[0026] During operation, the collection box 52 is lifted out of the water as a whole, and the water is quickly discharged through the screen 57. The fish fry remain on the screen 57 at the bottom of the magnetic ring 56. After the operator confirms the amount of fish fry collected through the observation window 58, he directly applies force to separate the magnetic connection between the magnetic ring 56 and the screen 57, and removes the screen 57 along with the fish fry as a whole. There is no need to disassemble the main structure of the collection box 52, realizing the simultaneous operation of fish-water separation and fish fry removal. The magnetic fixing method of the screen 57 can not only ensure the structural stability during water filtration, but also can be quickly disassembled by vertical lifting, simplifying the cumbersome process of traditional screen bolt fixing.

[0027] Furthermore, a bracket 8 is fixedly connected to the inner wall of the conical groove 1, a light strip 9 is fixedly connected to the surface of the bracket 8, and a sealing box 10 is fixedly connected to the top surface of the light strip 9.

[0028] During operation, the bracket 8 is welded to a preset position on the inner wall of the conical groove 1, and the light strip 9 is fixed to the surface of the bracket 8 by a buckle. The sealing box 10 covers the top of the light strip 9 and seals the joint with waterproof glue. After the light strip 9 is powered on, it emits light of a specific wavelength to attract fish fry to gather in the conical groove 1. The sealing box 10 prevents water vapor from penetrating and avoids short circuits in the light strip 9 circuit. This structure improves the efficiency of fish fry collection by using light to attract fish, while the sealed and protective design extends the service life of the light strip 9 in humid environments.

[0029] Furthermore, a mounting rod 11 is fixedly connected to one side of the conical groove 1 on an axisymmetric basis, and the surface of the mounting rod 11 is provided with several mounting holes;

[0030] During operation, the mounting rods 11 are symmetrically welded to the outer walls of both sides of the conical groove 1. The mounting holes are arranged at equal intervals along the length of the mounting rods 11. The device is fixed to the edge of the aquaculture pond or the mobile support by bolts passing through the mounting holes. The axisymmetric design ensures balanced installation force, and the multiple mounting holes provide freedom of height and angle adjustment to adapt to different water depths and pond structures. This structure simplifies the device installation process and enhances the stability and adaptability of the device in different application scenarios.

[0031] Furthermore, a cavity for a built-in control board 12 is provided on the back of the conical groove 1;

[0032] During operation, the control board 12 is embedded in the machined cavity on the back of the conical groove 1. The cavity opening is sealed by a cover plate. The control board 12 is connected to the solenoid valve 51, the water pump 55, and the power supply via a waterproof cable. The preset program controls the periodic opening and closing of the solenoid valve 51 and the pumping intensity of the water pump 55 to achieve a dynamic balance between negative pressure adsorption and fish fry protection. The integrated control module reduces external wiring interference, and the cavity sealing structure prevents water stains from corroding the control board 12, thereby improving the automation level and reliability of the device.

[0033] Working principle: The light strip 9 emits a specific spectrum of light to attract fish fry and eggs to the inlet area of ​​the conical trough 1, while the sponge block 7 simultaneously adsorbs the suspended fish eggs; after the water pump 55 starts, a negative pressure is formed in the collection box 52, and the water flow carries the fish fry through the guide channel 3 and guide pipe 4 at the bottom of the conical trough 1 into the collection box 52. The partition net 53 prevents the fish fry from entering the water pumping pipe 54 and guides the water flow out; the control board 12 periodically closes the solenoid valve 51 and stops the water pump 55 according to the preset program, interrupting the negative pressure adsorption to release the fish fry stuck at the partition net 53 and avoid damage caused by prolonged adsorption; after the collection is completed, the collection box 52 is lifted so that the water is discharged through the screen 57. The fish fry are stuck on the surface of the screen 57 at the bottom of the magnetic ring 56. After confirming the collection volume through the observation window 58, the magnetic ring 56 and the screen 57 are directly separated to complete the transfer of fish fry, realizing the integrated operation of trapping, preventing escape, low-damage collection and convenient separation.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
