Technical Field
[0001] This utility model relates to the technical field of greenhouses for freshwater shrimp farming, and in particular to a special greenhouse for freshwater shrimp farming ponds. Background Technology
[0002] With the continuous development of aquaculture, freshwater shrimp farming, as an important branch, has increasingly higher requirements for the farming environment. Temperature is a crucial factor in freshwater shrimp farming, directly affecting the shrimp's growth rate, reproductive capacity, and overall farming efficiency. To cope with temperature fluctuations caused by seasonal changes and ensure that freshwater shrimp grow in suitable temperature environments, many farmers have begun to use greenhouse technology to regulate the water temperature in their ponds. Greenhouses not only provide a stable growth environment but also effectively resist the impact of severe weather on the ponds, thereby improving the success rate and yield of freshwater shrimp farming.
[0003] In existing technologies, firstly, most greenhouse structures are fixed or semi-fixed, making it difficult to flexibly adjust them according to actual aquaculture needs. For example, in seasons with suitable temperatures, the greenhouse may become an obstacle restricting pond ventilation and light, affecting the shrimp's growth environment; while in cold seasons, insufficient greenhouse coverage or poor insulation may lead to a drop in pond water temperature, affecting shrimp growth rate and survival rate. Secondly, the unfolding and retraction of existing greenhouses often rely on manual operation, which is not only inefficient but also labor-intensive. Manual operation is particularly inconvenient when frequent adjustments to the greenhouse coverage are needed to cope with weather changes. Furthermore, manual operation may damage the greenhouse structure or cause insecure installation, affecting the greenhouse's lifespan and safety, resulting in poor practicality. Therefore, this utility model discloses a special greenhouse for freshwater shrimp farming ponds to solve the problems of poor flexibility and inconvenient operation in existing greenhouse technologies.

The limiting wheel is rotatably mounted on the protruding end of the connecting shaft.
[0008] Preferably, the diameter of the sliding rod is the same as the width of the second sliding groove, and each set of the first bracket and the second bracket has a first circular hole with the same diameter as the sliding rod at the position corresponding to the sliding rod. Both ends of the first bracket and the second bracket are rotatably mounted on the corresponding sliding rod.
[0009] Preferably, the positions where the first bracket and the second bracket intersect are provided with second circular holes of the same diameter as the support roller, and the first bracket and the second bracket are rotatably mounted on the support roller.

[0013] The beneficial effects of this utility model are:
[0014] This utility model provides a special greenhouse for freshwater shrimp farming ponds, which achieves flexible adjustment of the greenhouse structure through an adjustable component design. Multiple mounting frames slide within guide grooves, and with the coordinated action of rubber wheels and limit wheels, the mounting frames can move smoothly and orderly, thereby flexibly adjusting the greenhouse's coverage area according to actual farming needs. This design not only solves the problem of traditional greenhouses having fixed structures and difficulty adapting to seasonal changes, but also expands the ventilation and lighting area when the temperature is suitable, promoting shrimp growth; while in cold seasons, the coverage area can be reduced or insulation measures enhanced to ensure stable pond water temperature. Therefore, this utility model significantly improves the flexibility and adaptability of greenhouses, providing a more precise and efficient means of controlling the farming environment for freshwater shrimp farming.
[0015] The combination of the adjustment and reset components in this invention enables the automated deployment and retraction of the greenhouse. A servo motor drives the rotating rollers and winding wheels, while ropes, guided by the steering wheels, move the mounting frame, thus completing the deployment or retraction of the greenhouse. This process requires no manual intervention, significantly reducing labor intensity and improving operational efficiency. The advantages of automation are particularly evident when frequent adjustments to the greenhouse coverage area are needed to cope with weather changes. Furthermore, automation avoids structural damage or insecure installation caused by improper manual operation, thereby extending the greenhouse's lifespan and improving the safety of livestock farming.
[0016] This invention optimizes the connection between the mounting frame and components such as the sliding rod and support, ensuring the stability and durability of the greenhouse structure. Simultaneously, the damping rod and horizontal spring design in the reset assembly not only provide stable support for the mounting frame but also act as a buffer during the opening and closing of the greenhouse, further enhancing structural stability. Furthermore, the greenhouse of this invention possesses excellent heat preservation and ventilation performance, and can be flexibly adjusted according to actual needs, providing the optimal growth environment for freshwater shrimp. These advantages combined not only improve the success rate and yield of freshwater shrimp farming but also reduce farming costs, thereby significantly improving overall farming efficiency.

[0027] This utility model provides, for example Figures 1 to 5The illustration shows a special greenhouse for freshwater shrimp farming ponds, comprising: a base 1, the bottom of which is installed around the pond, with guide grooves 2 and first sliding grooves 3 on the upper surfaces of both sides of the base 1; side wall telescopic membranes 20 installed around the base 1; and a roof telescopic membrane 8 installed directly above the base 1. An adjustment component is provided on the base 1 for adjusting the folding of the greenhouse; a reset component is provided on the adjustment component for adjusting the unfolding of the greenhouse. This invention provides a special greenhouse for freshwater shrimp farming ponds, which, through the design of the adjustment component, achieves flexible adjustment of the greenhouse structure. Multiple sets of mounting frames 4 are slidably installed within the guide grooves 2, and with the coordinated action of rubber wheels 7 and limit wheels 6, the mounting frames 4 can move smoothly and orderly, thereby flexibly adjusting the coverage area of the greenhouse according to actual farming needs. This design not only solves the problem of traditional greenhouses having fixed structures and being difficult to adapt to seasonal changes, but also expands the ventilation and light area when the temperature is suitable, promoting shrimp growth; and reduces the coverage area or strengthens insulation measures in cold seasons to ensure stable pond water temperature. Therefore, this invention significantly improves the flexibility and adaptability of greenhouses, providing a more precise and efficient means of controlling the aquaculture environment for freshwater shrimp farming. The combination of the adjustment and reset components in this invention enables automated deployment and retraction of the greenhouse. A servo motor 23 drives the rotating roller 21 and the winding wheel 22, while the rope 11, guided by the steering wheel 10, moves the mounting frame 4, thus completing the deployment or retraction of the greenhouse. This process requires no manual intervention, greatly reducing labor intensity and significantly improving operational efficiency. The advantages of automated operation are particularly evident when frequent adjustments to the greenhouse coverage area are needed to cope with weather changes. Furthermore, automated operation avoids structural damage or insecure installation caused by improper manual operation, thereby extending the greenhouse's lifespan and improving aquaculture safety. This invention optimizes the connection method between the mounting frame 4 and components such as the sliding rod 19 and the support frame, ensuring the stability and durability of the greenhouse structure. Meanwhile, the damping rod 26 and horizontal spring 17 in the reset assembly not only provide stable support for the mounting frame 4, but also act as a buffer during the unfolding or retraction of the greenhouse, further enhancing the structural stability. Furthermore, the greenhouse of this invention also possesses excellent heat preservation and ventilation performance, and can be flexibly adjusted according to actual needs, providing the optimal growth environment for freshwater shrimp. These advantages combined not only improve the success rate and yield of freshwater shrimp farming, but also reduce farming costs, thereby significantly improving overall farming efficiency.
[0028] Furthermore, in this example, such as Figure 1 , Figure 3 and Figure 4As shown, the adjustment assembly includes multiple sets of mounting brackets 4, which are evenly arrayed and slidably installed in the guide groove 2. Each set of mounting brackets 4 has a rubber wheel 7 mounted at its bottom, which is rotatably mounted in the first sliding groove 3. A limit wheel 6 is installed on the outer wall of each set of mounting brackets corresponding to the position of the rubber wheel 7. Each set of limit wheels 6 is engaged and slidably mounted on the side wall of the guide groove 2. Each set of mounting brackets 4 has a loading groove 5 on both sides of its side wall, and a second sliding groove 18 is formed on both sides of each loading groove 5. Two sets of sliding rods 19 are vertically installed in each second sliding groove 18. A second bracket 13 is rotatably mounted on the upper sliding rod 19, and a first bracket 12 is rotatably mounted on the lower sliding rod 19. The other ends of the first bracket 12 and the second bracket 13 are both mounted on the sliding rods 19 in the second sliding grooves 18 of adjacent mounting brackets 4. The first bracket 12 and the second bracket 13 are installed at a cross position in the middle, and the first bracket 12 and the second bracket 13 rotate at the cross position. Each set of mounting frames 4 is equipped with a support roller 16 and a set of mounting cylinders 14 on the top side wall. A set of ropes 11 are installed on each set of mounting cylinders 14. A steering rod 9 is installed on the upper surface of the base 1 on one side of the mounting frame 4 located at one end of the base 1. A steering wheel 10 is provided on the top of the steering rod 9. A set of mounting blocks 15 are installed on both ends of the base 1 on one side of the steering rod 9. A rotating roller 21 is installed on the side wall of the two sets of mounting blocks 15. A winding wheel 22 is installed on both ends of the rotating roller 21. The rope 11 is wound around the winding wheel 22 after passing around the steering wheel 10. A servo motor 23 is installed at one corner of the base 1. A driven gear 25 is installed at the end of the rotating roller 21 located at one end of the servo motor 23. A drive gear 24 is installed at the output end of the servo motor 23. The drive gear 24 meshes with the driven gear 25. The adjustment component is the core part of the greenhouse of this utility model to achieve flexible adjustment. Its working principle mainly relies on the sliding installation and linkage mechanism of multiple sets of mounting frames 4. Specifically, multiple sets of mounting frames 4 are evenly arrayed and slidably installed in the guide grooves 2 of the base 1. Each set of mounting frames 4 has a rubber wheel 7 installed at its bottom, which is rotatably installed in the first sliding groove 3, providing support and guidance for the movement of the mounting frame 4. At the same time, a limit wheel 6 is also installed on the outer wall of each set of mounting frames 4 corresponding to the position of the rubber wheel 7. The limit wheel 6 is engaged and slidably installed on the side wall of the guide groove 2 to ensure that the mounting frame 4 remains stable during movement and does not shift or derail. Loading grooves 5 are opened on both side walls of the mounting frame 4, and a second sliding groove 18 is further opened in the loading groove 5. The sliding rod 19 is vertically installed in the second sliding groove 18. The first bracket 12 and the second bracket 13 are rotatably installed on the upper and lower sets of sliding rods 19, respectively, and their other ends are installed on the sliding rods 19 in the second sliding groove 18 of the adjacent mounting frame 4. The first bracket 12 and the second bracket 13 are cross-mounted in the middle and rotatably mounted with a support roller 16. This design allows the bracket to maintain a stable structural shape during unfolding or retraction.Rope 11, a key component connecting each mounting frame 4, is mounted together on the mounting cylinder 14 at the top of each set of mounting frames 4. After passing over the steering wheel 10 at the top of the steering rod 9, rope 11 is wound around the winding wheels 22 at both ends of the rotating roller 21. When the servo motor 23 is started, the drive gear 24 at its output end drives the driven gear 25 to rotate, thereby driving the rotating roller 21 and the winding wheels 22 to rotate. The rotation of the winding wheels 22 pulls the rope 11, thereby causing the mounting frame 4 to slide within the guide groove 2, realizing the greenhouse retraction operation.
[0029] Furthermore, in this example, such as Figure 1 , Figure 3 and Figure 4As shown, a groove is provided at the bottom of the mounting bracket 4 corresponding to the position of the rubber wheel 7. Connecting shafts are installed on the side walls of both ends of the groove. The rubber wheel 7 is rotatably mounted on the connecting shaft, and one end of the connecting shaft near the outer wall of the base 1 protrudes from the outer wall of the mounting bracket 4. The limiting wheel 6 is rotatably mounted on the protruding end of the connecting shaft. The diameter of the sliding rod 19 is the same as the width of the second sliding groove 18. A first circular hole with the same diameter as the sliding rod 19 is provided on each set of first brackets 12 and second brackets 13 corresponding to the position of the sliding rod 19. Both ends of the first bracket 12 and second bracket 13 are rotatably mounted on the connecting shaft. On the corresponding sliding rod 19, at the intersection of the first bracket 12 and the second bracket 13, a second circular hole with the same diameter as the support roller 16 is provided at the position corresponding to the support roller 16. The first bracket 12 and the second bracket 13 are rotatably mounted on the support roller 16. On each set of mounting cylinders 14, a third circular hole with the same diameter as the rope 11 is provided at the position corresponding to the rope 11. The rope 11 is slidably installed in the third circular hole on each set of mounting cylinders 14 at the corresponding position. On the two sets of mounting blocks 15, a fourth circular hole with the same diameter as the rotating roller 21 is provided at the position corresponding to the rotating roller 21. The rotating roller 21 is rotatably installed in the fourth circular hole. A rubber wheel 7 is installed in the bottom groove of the mounting frame 4 via a connecting shaft. A limiting wheel 6 is installed on the protruding part of the outer end of the connecting shaft. The rubber wheel 7 rolls in the first sliding groove 3 to provide support for the movement of the mounting frame 4. The limiting wheel 6 cooperates with the side wall of the guide groove 2 to achieve limiting guidance, ensuring stable movement of the mounting frame 4. The sliding rod 19 is tightly fitted with the second sliding groove 18. The first bracket 12 and the second bracket 13 are rotatably installed on the sliding rod 19 through the first circular hole, and their intersection is rotatably installed on the support roller 16 through the second circular hole. When the mounting frame 4 moves... The sliding rod 19 slides to drive the bracket to rotate, and the support roller 16 provides support for the bracket's intersection point and allows it to rotate flexibly, ensuring the stable and coordinated movement of the bracket. The third circular hole on the mounting cylinder 14 guides the rope 11 to slide, ensuring the accurate movement trajectory of the rope 11 to pull or release the mounting frame 4. The fourth circular hole on the mounting block 15 provides a stable mounting position for the rotating roller 21. The rotating roller 21 rotates in the fourth circular hole, driving the winding wheel 22 to wind or release the rope 11, providing power for the automated unfolding and retraction of the greenhouse. All components work together to achieve flexible adjustment and stable operation of the greenhouse structure.
[0030] Furthermore, in this example, such as Figure 5As shown, the reset assembly includes multiple sets of damping rods 26. The two ends of each set of damping rods 26 are mounted on the top sidewall of an adjacent mounting frame 4, and a horizontal spring 17 is fitted onto each set of damping rods 26. In this invention, the reset assembly plays a crucial role in assisting the adjustment assembly and ensuring the smooth unfolding of the greenhouse. The reset assembly mainly includes multiple sets of damping rods 26 and horizontal springs 17. The two ends of each set of damping rods 26 are mounted on the top sidewall of an adjacent mounting frame 4. When the greenhouse unfolds or retracts under the action of the adjustment assembly, the damping rods 26 provide a certain resistance, slowing down the movement speed of the mounting frame 4 and preventing structural damage or instability due to excessive speed. The horizontal springs 17 are fitted onto the damping rods 26, storing elastic potential energy when the greenhouse is retracted, thus assisting the mounting frame 4 in retracting smoothly and orderly. This design not only enhances the stability of the greenhouse structure, but also makes the greenhouse more stable and reliable during the folding process. When the greenhouse is unfolded, as the servo motor 23 rotates, the drive gear 24 drives the driven gear 25 to rotate, thereby driving the drive rotating rod 21 to rotate. At this time, the rope 11 wound on the winding wheel 22 will be released. Then, under the action of the horizontal spring 17 and the damping rod 26, the mounting frame 4 will gradually unfold completely.
