Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aquaculture, in particular to a screening device suitable for cultivating mandarin fish in land-based circular ponds. Background Art
[0002] In the past, hemispherical screeners with grids were mainly used for screening mandarin fish. Before using the screener, it is necessary to use a fishing net to gather all the fish together to facilitate workers to use the screener for screening. However, this method is cumbersome to operate, especially in the case of farming mandarin fish in land-based circular ponds. Since the bottom of the land-based circular pond is in the shape of a pot bottom, the traditional net causes the mandarin fish to escape from the bottom. Therefore, it is necessary to repeatedly pull the net to gather the fish, which is very time-consuming and laborious. Therefore, a screening device suitable for farming mandarin fish in land-based circular ponds is proposed. Utility Model Content

[0006] Preferably, a drainage pipe is fixedly installed at the bottom of the land-based circular pool, and a water inlet pipe is fixedly connected to the land-based circular pool.
[0007] Preferably, the number of the wristbands is two, and the number of the footbands is two.
[0008] Preferably, the material of the float is a hollow plastic ball, and the diameter of each float is 10-15 cm.
[0009] Preferably, a hook is sleeved on the lower net belt, and a stainless steel chain is clamped on the hook.
[0010] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:
[0011] In the utility model, a float is arranged on the upper net belt, so that the upper part of the plastic net placed in the water can be floated, and then a stainless steel chain is connected to the lower net belt, so that the lower part of the plastic net can be sunk to the bottom of the water, so that fish can be placed inside the plastic net, and fish smaller than the holes of the plastic net can drill out, and fish larger than the holes of the plastic net are intercepted, thereby completing the screening and effectively preventing the fish from escaping from the gaps. The use is convenient and quick, and the reliability of the device is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0019] A screening device suitable for cultivating mandarin fish in land-based circular ponds provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.
[0020] Example:
[0021] Combination Figure 1-4As shown, the utility model provides a screening device suitable for land-based circular pond culture of mandarin fish, comprising a land-based circular pond 1, a drainage pipe 2 is fixedly installed at the bottom of the land-based circular pond 1, when the land-based circular pond 1 needs to be drained, it can be done by opening the drainage pipe 2, a water inlet pipe 3 is fixedly connected to the land-based circular pond 1, when the water needs to be changed, it is only necessary to open the drainage pipe 2 first to let the water inside the land-based circular pond 1 flow out, then close the drainage pipe 2, and then open the water inlet pipe 3 to change the water, a plastic net 4 is placed inside the land-based circular pond 1, according to the size of the plastic net 4, fish smaller than the net holes of the plastic net 4 can drill out, so as to carry out the next step of screening, and fish larger than the net holes of the plastic net 4 are intercepted and collected, the top of the plastic net 4 is movably connected with a net belt 5, and a wristband 6 is sleeved on the net belt 5, and the number of the wristbands 6 is two, which is convenient for the operator to put it on his hand, drag the plastic net 4, and then Fish gathering and screening, the upper net belt 5 is sleeved with a hook 7, and the hook 7 is clamped with a float 8. The material of the float 8 is a hollow plastic ball, and the diameter of each float 8 is 10-15 cm. When the plastic net 4 is placed in the land-based circular pool 1, the float 8 will automatically float up, extending the plastic net 4 to facilitate personnel to work. The bottom of the plastic net 4 is movably connected with a lower net belt 9, and the lower net belt 9 is sleeved with a foot ring 10. The number of the foot rings 10 is two, and the wristband 6 is consistent with the foot ring 10 in appearance, but the size is different, which is convenient for the operator to put it on the foot, drive the recovery of the plastic net 4, and smoothly gather and screen the fish. The lower net belt 9 is sleeved with a hook 7, and the hook 7 is clamped with a stainless steel chain 11. The stainless steel chain 11 can allow the lower part of the plastic net 4 to sink to the bottom of the water, stretch the bottom of the plastic net 4, prevent fish from escaping, and play a stabilizing role.
[0022] The working principle and use process of the utility model are as follows: first, a plastic net 4 is placed inside a land-based circular pool 1. At this time, the float 8 will float to the surface under the action of buoyancy, and simultaneously drive the upper half of the plastic net 4 to extend. At the same time, because the self-gravity of the stainless steel chain 11 is greater than its own buoyancy, it will drive the lower half of the plastic net 4 to sink to the bottom of the land-based circular pool 1, allowing the lower half of the plastic net 4 to stretch out. At this time, the external device is removed so that the fish can flow into the plastic net 4, and then the staff is allowed to go down into the land-based circular pool 1, and put the bracelet 6 on the wrist, and then put the foot ring 10 on the ankle. At this time, the plastic net 4 will, with the assistance of the staff, intercept the fish whose size is larger than the specification of the plastic net 4, and drill out the fish whose size is smaller than the specification of the plastic net 4, thereby completing the screening.
[0023] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
