Description

Technical Field

[0001] This utility model relates to a shading device, and in particular to a high-density fish farming shading device, belonging to the technical field of aquaculture equipment. Background Technology

[0002] With the intensive development of the aquaculture industry, high-density fish farming has been widely adopted due to its ability to significantly increase yield per unit volume of water. However, in high-density aquaculture environments, precise control of light intensity is crucial for fish growth: excessive light can lead to a sudden rise in water temperature and excessive algae growth, which not only reduces dissolved oxygen levels but may also trigger stress responses in fish; while insufficient light can affect the photosynthesis of plankton and disrupt the ecological balance of the aquatic body. Therefore, efficient and stable shading devices have become key equipment for ensuring aquaculture efficiency in high-density fish farming scenarios.

[0003] Chinese Patent Publication No. CN211407267U discloses a shading device for sturgeon farming, comprising an adjustment mechanism, a stabilizing mechanism, and a moving mechanism. The adjustment mechanism includes a fixed block, a fixed rod, and a support rod. The stabilizing mechanism includes a stabilizing block, a circular block, a connecting rod, and an arc tube. A slider is provided inside the circular block. The moving mechanism includes a rotating ring, a moving rod, and a semi-circular tube. A magnet is provided on the surface of the semi-circular tube. The fixed rod and the support rod are both in a vertical position. The top of the support rod passes through the fixed rod and connects to the stabilizing block. The circular block and the rotating ring are both located outside the stabilizing block, and the bottom of the rotating ring is in contact with the top of the circular block. A shading net is provided between the moving rod and the connecting rod. The upper side of the circular tank for sturgeon farming is covered by the unfolded shading net, which provides shade for the sturgeon in the tank, preventing them from being exposed to excessive sunlight and dying. The shading range can be changed so that the sturgeon receive both sunlight and shade, which is conducive to the healthy growth of the sturgeon.

[0004] However, in the use of existing technology, the stabilizing block, support rod, and moving rod of the existing device are connected by multiple nested components. When disassembling, it is necessary to disassemble the fixing ring, limiting mechanism and other components in sequence, which is time-consuming and labor-intensive. In high-density fish farming environment, the shading device needs to be cleaned or replaced regularly to prevent algae attachment and bacterial growth. The complex structural design increases the maintenance difficulty. Therefore, a high-density fish farming shading device is proposed. Summary of the Invention

[0028] like Figure 1-3 As shown, this utility model embodiment provides a high-density fish farming shading device, including a pond body 10, a shading cloth 11, and a fixing plate 20;

[0029] In one embodiment, there are several fixing plates 20, which are detachably connected to the outside of the pool body 10. A vertical plate 21 is hinged to one side of the fixing plate 20, and a horizontal plate 22 is hinged to the side of the vertical plate 21 away from the fixing plate 20. The fixing plate 20 and the vertical plate 21, and the vertical plate 21 and the horizontal plate 22 are fixed by limiting components. Several through slots 23 are provided on the horizontal plate 22. Several binding ropes 12 are fixedly connected to the sunshade cloth 11. The binding ropes 12 pass through the through slots 23 to fix the sunshade cloth 11 to the bottom of the horizontal plate 22. An adjustment component for fastening the connection is provided on the side of the fixing plate 20 near the pool body 10. The limiting component includes a limiting rod 25, a limiting plate 24, and a nut 26. The limiting rod 25 passes through the area near the hinge between the fixing plate 20 and the vertical plate 21, and the area near the hinge between the vertical plate 21 and the horizontal plate 22. One end of the limiting rod 25 is fixedly connected to the limiting plate 24, and the other end is threaded and threadedly connected to the nut 26.

[0030] The fixed plate 20 is detachably connected to the outside of the pool body 10, which makes it easy to flexibly adjust the number and position of installation according to the size of the pool body 10, and also facilitates disassembly and maintenance later. The vertical plate 21 is hinged to the fixed plate 20, and the horizontal plate 22 is hinged to the vertical plate 21. The relative angle of the three can be adjusted by rotation, thereby flexibly changing the coverage height and range of the sunshade cloth 11 to adapt to different light requirements.

[0031] The limiting rod 25 in the limiting assembly passes through the vicinity of the hinge. By tightening the nut 26, the angle between the fixing plate 20 and the upright plate 21, and between the upright plate 21 and the horizontal plate 22 can be fixed to prevent displacement due to external force during use and to ensure the stability of the shading. Loosening the nut 26 allows the angle to be adjusted again, making the operation simple and convenient.

[0032] The sunshade cloth 11 is fixed by passing the binding rope 12 through the through groove 23 of the horizontal plate 22. No complicated connectors are needed. Installation can be completed by simply binding. When disassembling, the binding rope 12 can be untied to quickly remove the sunshade cloth 11, which is convenient for cleaning, replacement or folding and storage, reducing maintenance difficulty.

[0033] The adjustment component is used to fasten the fixing plate 20 to the pool body 10, ensuring that the fixing plate 20 is not easy to loosen after installation, thus improving the stability of the overall structure.

[0034] In one embodiment, the adjustment assembly includes a plate 27 and a threaded rod 28. The plate 27 is fixed to the side of the fixed plate 20 near the pool body 10. The threaded rod 28 passes through the plate 27 and is threadedly connected to the plate 27. One end of the threaded rod 28 near the pool body 10 is rotatably connected to a clamping block 29 via a bearing. The fixed plate 20 is provided with a groove 203 corresponding to the position of the clamping block 29. A slider 204 is fixed to one side of the clamping block 29 and is slidably connected in the groove 203.

[0035] The limiting rod 25 passes through the vicinity of the hinge, with one end limited by the limiting plate 24 and the other end locked by the nut 26. The structure is simple and the connection is reliable. It can effectively limit the rotational freedom at the hinge and ensure that the angle between the fixed plate 20, the vertical plate 21 and the horizontal plate 22 is fixed.

[0036] Nut 26 is threadedly connected to limit rod 25. Loosening nut 26 can release the fixation, which facilitates quick adjustment of the angle of each component. The operation is convenient and does not require disassembly of complex structures, reducing the time cost of adjustment and maintenance.

[0037] In one embodiment, the sunshade cloth 11 has several through holes 13 evenly distributed around its circumference. The through holes 13 are used to thread ropes through to bind and fix the folded sunshade cloth 11. The side surface of the clamping block 29 near the pool body 10 is provided with anti-slip ridges 205, which are evenly distributed along the length of the clamping block 29. The end of the threaded rod 28 away from the clamping block 29 is fixedly connected to a protrusion 201. The side of the protrusion 201 away from the threaded rod 28 is provided with a groove 202, which is an internal hexagonal groove. The through slots 23 are evenly spaced along the length of the horizontal plate 22, and the number of through slots 23 is adapted to the number of binding ropes 12 on the sunshade cloth 11.

[0038] Plate 27 is fixed to fixed plate 20, and threaded rod 28 is threadedly connected to plate 27. Rotating threaded rod 28 can drive clamping block 29 to move closer to or away from pool body 10, thereby adapting to the edge of pool body 10 of different thicknesses and improving the versatility of the device for different pool bodies.

[0039] The clamping block 29 is slidably connected to the slide groove 203 of the fixed plate 20 via the slider 204. The slide groove 203 and the slider 204 serve as guides to ensure that the clamping block 29 moves in a straight line, avoids deviation, and ensures the clamping effect.

[0040] The through holes 13 on the edge of the sunshade cloth 11 make it easy to thread ropes through. After the sunshade cloth 11 is folded, it can be tied and fixed with ropes, reducing storage space and making it convenient for storage and transportation.

[0041] The anti-slip texture 205 on the surface of the clamping block 29 can increase the friction with the pool body 10, prevent relative sliding between the fixing plate 20 and the pool body 10, and improve the connection stability.

[0042] The protrusion 201 and groove 202 at the end of the threaded rod 28 make it easier to rotate the threaded rod 28 with an Allen wrench, making the operation more labor-saving and convenient;

[0043] The number of through grooves 23 and binding ropes 12 are matched to ensure that the edge of the sunshade cloth 11 is evenly stressed, avoiding the sunshade cloth 11 from shifting or tearing due to uneven distribution of fixing points, thus improving its service life.

[0044] When this utility model is in operation: First, the fixing plate 20 is attached to the outer wall of the pool body 10. Then, the threaded rod 28 is rotated by inserting an Allen wrench into the groove 202 of the protrusion 201. Since the threaded rod 28 is threadedly connected to the plate 27, the rotation drives the clamping block 29 to move towards the pool body 10. The slider 204 slides along the slide groove 203 to play a guiding role until the clamping block 29 is in close contact with the outer wall of the pool body 10. The anti-slip ridges 205 on the surface of the clamping block 29 increase the friction and ensure that the fixing plate 20 is firmly fixed. The spacing of several fixing plates 20 is adjusted according to the size of the pool body 10.

[0045] Next, rotate the hinge between the upright plate 21 and the fixed plate 20, and the hinge between the horizontal plate 22 and the upright plate 21. Then, insert the limiting rod 25 through the vicinity of the corresponding hinge and tighten the nut 26. The angle of the three is fixed by the cooperation of the limiting plate 24 and the nut 26 to prevent displacement due to external force during use. Unfold the sunshade cloth 11 so that the binding ropes 12 pass through the through slots 23 of the horizontal plate 22 one by one. Fix the sunshade cloth 11 to the bottom of the horizontal plate 22 by binding the binding ropes 12. The number of through slots 23 and binding ropes 12 are matched to ensure that the sunshade cloth 11 is evenly stressed and covers flat. If it is necessary to clean / replace the sunshade cloth 11, untie the binding ropes 12 to remove it. After folding, pass the rope through the through hole 13 to tie and store it. Loosen the nut 26 to rotate the upright plate 21 or the horizontal plate 22. If it is necessary to disassemble the device, rotate the threaded rod 28 in the opposite direction to make the clamp 29 disengage from the pool body 10, and then remove the fixed plate 20 and related components. The operation is convenient and efficient.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
