Abstract
Description
Technical Field
[0001] This utility model relates to a shading device for aquaculture, and more particularly to a shading device for sturgeon farming. Background Technology
[0002] Sturgeon are an ancient and precious group of freshwater or anadromous fish, hailed as "living fossils" of the water, with an evolutionary history dating back to the Cretaceous period 200 million years ago. Sturgeon are large fish with high edible value; all parts of their body (including the skeleton) except for the bony plates on the surface are edible. They are believed to have effects such as clearing heat and detoxifying, beautifying the skin, and nourishing the brain. Currently, due to overfishing, habitat destruction, blocked migration routes, long sexual maturity cycles, and low natural reproduction rates, the number of wild sturgeon has drastically decreased. Commercial aquaculture (such as Siberian sturgeon) is now used to reduce reliance on wild resources.
[0003] In sturgeon farming, sunlight has a significant impact on sturgeon growth, behavior, and water quality. However, sturgeon are quite sensitive to direct, strong light, requiring scientific management to balance their light needs with potential risks. As bottom-dwelling fish, sturgeon naturally inhabit the lower and middle layers of water and have long adapted to low-light environments. Direct sunlight can easily cause sturgeon to avoid light (such as gathering in shaded areas), reducing feeding and activity, and affecting growth efficiency. However, light exposure cannot be completely eliminated. The natural light cycle (day-night cycle) regulates sturgeon endocrine function (such as growth hormone and gonadal development). Prolonged darkness or continuous strong light can disrupt their physiological rhythms. Therefore, a device that can regulate the light in the aquaculture pond is needed. Utility Model Content
[0004] The purpose of this invention is to provide a shading device for sturgeon farming. It can effectively improve the shading effect and enhance the fish farming results.
[0005] The technical solution of this utility model is as follows: A shading device for sturgeon farming includes a support frame. The support frame is located on the upper side of the fish pond and has a first mounting seat and a second mounting seat at its front and rear ends, respectively. A first winding roller is provided on the first mounting seat, and a first shading curtain is provided outside the first winding roller. A motor is provided on one side of the first winding roller to drive the winding roller to rotate. A second winding roller is provided on the second mounting seat, and a second shading curtain is provided on the second winding roller. Springs are provided on both sides of the second shading curtain, and the length of the springs is greater than the length of the second shading curtain. The ends of the springs are connected to the first shading curtain.
[0006] In the aforementioned shading device for sturgeon farming, the lengths of the first and second shading curtains are not less than the distance between the first and second mounting bases, and the length of the coil spring is twice the length of the second shading curtain.
[0007] In the aforementioned shading device for sturgeon farming, the inner wall of the bracket is provided with multiple sets of guiding mechanisms for guiding the first shading curtain and the coil spring.
[0008] In the aforementioned shading device for sturgeon farming, the guiding mechanism includes a support plate on the side wall of the bracket, an mounting seat on the upper side of the support plate, a mounting groove inside the mounting seat, a spring at the bottom of the mounting groove, a guide wheel bracket that can move relative to the mounting seat on the upper side of the spring, and a guide wheel in the guide wheel bracket.
[0009] Compared with the prior art, the present invention has the following advantages:
[0010] This application provides a first mounting base and a second mounting base for mounting first and second sunshades of different specifications. The second sunshade is provided with springs on both sides, and the ends of the springs are connected to the first sunshade, so the sunshade effect can be adjusted. Attached Figure Description

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0017] Example 1. A shading device for sturgeon farming, comprising as follows: Figure 1-2 As shown, the device includes a bracket 1, which is located on the upper side of the fish pond and has a first mounting seat 2 and a second mounting seat 3 at its front and rear ends, respectively. The first mounting seat 2 has a first winding roller 7, and a first sunshade curtain 8 is provided outside the first winding roller 7. A motor 9 that drives the winding roller 7 to rotate is provided on one side of the first winding roller 7. The second mounting seat 3 has a second winding roller 10, and a second sunshade curtain 11 is provided on the second winding roller 10. The second sunshade curtain 11 has coil springs 12 on both sides, and the length of the coil springs 12 is greater than the length of the second sunshade curtain 11. The ends of the coil springs 12 are connected to the first sunshade curtain 8.
[0018] The lengths of the first sunshade curtain 8 and the second sunshade curtain 11 are not less than the distance between the first mounting base 2 and the second mounting base 3, and the length of the coil spring 12 is twice the length of the second sunshade curtain 11.
[0019] The first sunshade curtain 8 and the second sunshade curtain 11 of this application are two different specifications of sunshade curtains, that is, they have different sunshade levels. The light-blocking degree of the second sunshade curtain 11 is higher than that of the first sunshade curtain 8. In the initial position of this application, the second sunshade curtain 11 and the coil spring 12 on one side of the second sunshade curtain 11 are both wound on the second take-up roller 10. The first sunshade curtain 8 is located between the first take-up roller 7 and the second take-up roller 10. The first take-up roller 7 is driven by the motor 9 to realize forward and reverse rotation. When the light is weak and no shading is needed, the first take-up roller 7 rotates, causing the first sunshade curtain 8 to be completely rolled up on the first take-up roller 7. At this time, there is no sunshade curtain between the first take-up roller 7 and the second take-up roller 10, only the coil spring 12, which is used to provide appropriate light. If the light is particularly strong, the motor 9 continues to rotate, pulling the second sunshade curtain 11 towards the first mounting base 2 to improve the shading effect. If the first sunshade curtain 8 is needed for shading, the motor reverses, and under the action of the coil spring 12, the second sunshade curtain 11 and the coil spring 12 are rolled up on the second take-up roller 10, thereby achieving adjustment of the shading effect.
[0020] Example 2. The configuration is as follows: Figure 3-4 As shown, based on Embodiment 1, the inner sidewall of the bracket 1 is provided with multiple sets of guiding mechanisms for guiding the first sunshade 8 and the coil spring 12. The guiding mechanism includes a support plate 13 on the sidewall of the bracket, a mounting seat 14 on the upper side of the support plate 13, a mounting groove 15 in the mounting seat 14, a spring 16 at the bottom of the mounting groove 15, a guide wheel bracket 17 on the upper side of the spring 16 that can move relative to the mounting seat 14, and a guide wheel 18 in the guide wheel bracket 17, thereby guiding the first sunshade 8 and the coil spring 12 with better reliability.
