Technical Field
[0001] The utility model relates to the technical field of fish breeding, in particular to a bird-proof net for fish breeding which is easy to retract and deploy. Background Art
[0002] In the process of fish farming, bird-proof netting is an important protective measure to protect the fish in the pond from natural enemies, especially birds. Bird-proof netting is usually made of corrosion-resistant woven material and can effectively cover the surface of the fish pond.
[0003] Currently, the deployment and retraction of existing bird-proof nets on the market are relatively cumbersome, especially for large fish ponds, often requiring significant time and manpower to stretch and tighten the nets. Due to their large size, the nets are prone to wrinkling during deployment, resulting in uneven coverage and even holes. Furthermore, retracting the nets often requires gradual disassembly or manual rewinding, adding to the complexity and time-consuming nature of aquaculture operations. This time-consuming and labor-intensive process is particularly noticeable in large-scale aquaculture.
[0004] Therefore, there is an urgent need for a fish farming bird-proof net that is convenient to retract and release to solve the technical defects proposed in the above-mentioned technology. Utility Model Content
[0005] The purpose of the present invention is to provide a bird-proof net for fish farming that is easy to retract and unfold, so as to solve the problem in the above-mentioned background technology that it often takes a lot of time and manpower to stretch or tighten the net.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bird-proof net for fish farming that is easy to retract and deploy, comprising a bracket and a bottom groove, wherein the bracket is arranged vertically in multiple groups, a track is provided at the top of each bracket, a notch is provided at the top of each track, a spring is fixedly connected to the bottom end of the inner wall of the track, a movable plate is fixedly connected to the end face of the spring, a rolling ball is provided at the top of the movable plate, multiple groups of rolling balls are embedded in the track, a rope is fixed to the outside of the rolling balls near the edge of the bracket, vertical rods are welded to the top of each rolling ball, and a woven mesh is fixed horizontally between the tops of the vertical rods.
[0007] Preferably, the diameter of the vertical rod is smaller than the inner diameter of the slot, and the number of the rolling balls is arranged according to the width of the fish pond.
[0008] Preferably, a fixing bolt is welded on one side of the outer wall of the bracket, and the rope is tied around the fixing bolt.
[0009] Preferably, the brackets are arranged horizontally with equal spacing.
[0010] Preferably, slots are provided at both ends of the bracket along the length direction, and when the brackets are distributed vertically, they are plugged into each other through the slots.
[0011] Preferably, the movable plates are two groups of semi-arc plates that match the size of the rolling ball, and the movable plates are arranged on the left and right sides below the rolling ball.
[0012] Preferably, a bottom groove is formed at the bottom end of each bracket, an insert rod is embedded in the bottom groove, a fixing sleeve is sleeved on the outside of the bottom groove, and a fixing bolt is fixedly connected between the fixing sleeve and the insert rod.
[0013] Preferably, auxiliary legs are welded to the four corners of the bottom end of the insertion rod, and the auxiliary legs and the tip of the insertion rod are both tapered.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the bird-proof net for fish farming that is easy to retract and deploy not only realizes that the net only needs to be pulled to be retracted and deployed, thereby reducing the difficulty and time of operation, but also realizes that it is not easy to be damaged during the deployment process, and no settlement arc is formed in the middle position of the net surface, and also achieves better windproof and stable effects;
[0015] (1) By providing a woven mesh, a slot, a track, a movable plate, a fixed bolt, a rope, a spring, a ball, and a slot, when the woven mesh is placed, personnel are arranged at both ends of the fish pond. They only need to pull the balls in the outermost row through the ropes. When the balls are in place, the woven mesh can be opened, and then the ropes can be tied to the fixed bolts. When it needs to be folded, the ropes can be untied. By moving the woven mesh toward the horizontal center line of the bracket, the balls move in the track, and the woven mesh can be folded. When the balls move in the track, in order to avoid poor sliding, the bottom end of the balls uses a movable plate supported by a spring, so that the balls can overcome the friction resistance during pulling and have a certain amount of movement space. The structure only requires the operator to pull to realize the folding and unfolding of the net, and there is no need to disassemble the woven mesh from the bracket bit by bit, which reduces the difficulty of operation and the time consumed. It is suitable for large-scale fish pond farming.
[0016] (2) The woven mesh is supported by brackets, and each bracket is connected to each other through the slots at the ends thereof. The woven mesh can be applied to large-scale fish pond farming. Multiple brackets can be used in combination, and the woven mesh can be densely combined and not easily damaged during the arrangement process. The mesh is fixed at multiple points by the rolling balls, and no sinking arc is formed in the middle of the mesh.
[0017] (3) By setting up a bracket, a bottom groove, a plug rod, a support leg, a fixing sleeve, and a fixing bolt, a bottom groove is set at the bottom of the bracket. The plug rod is pulled out from the bottom of the bottom groove and inserted into the mud pond soil. Four sets of auxiliary support legs form a support around the plug rod. The position of the plug rod is adjusted by the fixing sleeve and fixed by the fixing bolt. The bracket can be firmly supported in the fish pond, and the windproof and stable effect is better.
