Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and in particular relates to a fishery breeding shed. Background Art

[0002] Aquaculture is the production activity of breeding, cultivating, and harvesting aquatic plants and animals under human control. Aquaculture can be carried out in a variety of methods, including extensive, intensive, and high-density intensive aquaculture. Extensive aquaculture involves releasing seedlings into small or medium-sized natural water bodies and raising aquatic products entirely on natural feed, such as fish farming in lakes and reservoirs and shellfish farming in shallow waters. Intensive aquaculture involves raising aquatic products in smaller water bodies using feed and fertilization, such as pond fish farming, cage fish farming, and pen fish farming. High-density intensive aquaculture utilizes methods such as flowing water, temperature control, oxygenation, and feeding high-quality feed to achieve high yields in aquaculture ponds, such as high-density flowing water fish and shrimp farming.

[0003] At present, the use of greenhouses for aquaculture is becoming more and more common in high-density intensive aquaculture. The existing aquaculture greenhouses are sealed and airtight on all sides, with poor ventilation, which will affect the quality of aquaculture products and reduce the efficiency and benefits of aquaculture.

[0004] The utility model patent with publication number CN210054298U proposes a ventilation device and a crayfish breeding greenhouse, comprising a ventilation roller shutter for rolling up the greenhouse film on the sunlit side of the greenhouse to form a vent; a deflector disposed within the greenhouse near the vent; the deflector's side near the vent being mounted on a shaft seat via a rotating shaft; the ventilation device also includes a drive device for driving the deflector to tilt upward; the patent also discloses a crayfish breeding greenhouse, comprising the ventilation device described above. The patented technical solution is capable of tilting the deflector during ventilation, allowing cold air entering the greenhouse to be blown toward the top of the greenhouse by the deflector, avoiding direct airflow into the pond; the drive device includes a second retractable rope and the ventilation roller shutter, which synchronously tilts the deflector when the ventilation roller shutter is rolling up for ventilation and simultaneously lowers the deflector when the greenhouse film is lowered.

[0005] However, this patented technical solution has certain defects during use: when the ventilation roller shutter machine performs roller shutter ventilation, the guide plate is simultaneously lifted up, and the guide plate is kept at a fixed angle blowing toward the top of the greenhouse, resulting in a fixed wind direction entering the greenhouse, which can easily slow down the air circulation speed in the greenhouse and reduce the ventilation efficiency.

[0026] like Figure 1-4 As shown, a fishery breeding shed includes a breeding shed body, side walls 2 are provided at the left and right ends of the breeding shed body, a rear wall 3 is provided on the rear side of the breeding shed body, the front side and the top of the breeding shed body are covered with a shed film 1, the shed film 1 at the bottom front side of the breeding shed body is rolled up by a lifting mechanism to form a front vent 4, an angle adjustment mechanism is provided at the front vent 4, side vents 5 are opened on the walls 2 on both sides, and ventilation fans 6 are provided at the side vents 5.

[0027] The angle adjustment mechanism includes multiple guide plates 7, which are arranged along the length direction of the breeding shed body. Both ends of the guide plates 7 are rotatably connected to the side walls 2. By changing the inclination angle of the guide plates 7, the air inlet angle at the front vent 4 can be changed.

[0028] Specifically, the angle adjustment mechanism also includes a support frame 8, which is installed at the front vent 4. The support frame 8 plays a supporting role so that the outside air can blow smoothly into the breeding shed body. The upper part of the support frame 8 is fixedly connected to the mounting plate 9, and the top surface of the mounting plate 9 is installed with a first motor 10. The output end of the first motor 10 is fixedly connected to the first bevel gear 11, and the first bevel gear 11 is meshed with the second bevel gear 12. The middle part of the second bevel gear 12 is fixedly connected to the rotating shaft 13, and the rotating shaft 13 extends downward through the mounting plate 9. The rotating shaft 13 is rotatably connected to the mounting plate 9. The bottom of the rotating shaft 13 is fixedly connected to the screw 14, and the outer wall of the screw 14 is threadedly connected to the sliding sleeve 15, and the sliding sleeve 15 is fixedly connected to the lifting plate 17 through the connecting rod 16.

[0029] Specifically, the guide plate 7 includes a baffle 18 and an adjustment plate 19, which are fixedly connected. A bending portion is provided in the middle of the adjustment plate 19, which is rotatably connected to the support frame 8. One end of the adjustment plate 19 is movably connected to the lifting plate 17, and the other end is fixedly connected to the baffle 18. Specifically, a positioning lever is installed at one end of the adjustment plate 19, and a horizontally arranged slot hole is provided on the lifting plate 17 corresponding to the position of the positioning baffle. The positioning lever is arranged in the slot hole. When the lifting plate 17 moves up and down, the slot hole drives the positioning lever to move up and down, and at the same time, the positioning lever can move left and right in the horizontal direction within the slot hole.

[0030] During use, the lifting and lowering of the lifting plate 17 can drive one end of the adjustment plate 19 to rise and fall synchronously. Since the bent portion of the adjustment plate 19 is rotatably connected to the support frame 8, when the lifting plate 17 descends, it drives one end of the adjustment plate 19 to descend, and the other end of the adjustment plate 19 to rise, and at the same time drives the inclination angle of the baffle 18 to change, thereby adjusting the air inlet angle.

[0031] Specifically, the lifting mechanism includes a pressure rod 20, which is fixedly connected to the bottom of the greenhouse film 1. The two ends of the pressure rod 20 can be fixed to the ground by a buckle structure. When ventilation is required, the buckle structure is opened to lift the pressure rod 20. In this embodiment, the buckle structure is a commonly used structure in the field. The end of the pressure rod 20 is connected to a pull rope 21, and the other end of the pull rope 21 is fixedly connected to a rope reel 22. The rope reel 22 is connected to a second motor 23, which is fixedly installed above the front vent 4. The second motor 23 drives the rope reel 22 to rotate. The rotation of the rope reel 22 drives the pull rope 21 to be wound around the rope reel 22 or to be wound off the rope reel 22, thereby realizing that the pressure rod 20 drives the greenhouse film 1 to rise or fall, allowing air to enter the interior of the breeding shed through the front vent 4.

[0032] A limit block 24 is provided at the end of the pressure rod 20, and the limit block 24 is slidably connected in the limit slide 25. The limit slide 25 is fixedly connected to the lower inner wall of one side wall 2. The limit block 24 can slide up and down in the limit slide 25, thereby realizing the guidance and restriction of the moving trajectory of the limit block 24 by the limit slide 25.

[0033] Specifically, the ventilation fan 6 includes a frame 26, the middle part of the frame 26 is connected to the fan blades 27 through a bearing seat, a third motor 28 is installed on one side of the frame 26, and the output end of the third motor 28 is connected to the fan blades 27 by transmission, wherein the transmission connection method can specifically be a belt connection transmission, but is not limited to this connection method.

[0034] Specifically, both sides of the frame 26 are detachably connected with a filter 29, and the filter 29 can prevent mosquitoes from entering the breeding shed.

[0035] The outside of the frame 26 is fixedly connected to the air duct check valve by bolts. The air duct check valve can control the ventilation of the greenhouse. When there is no ventilation, the air duct check valve is closed, and when ventilation is required, the air duct check valve is opened. The check valve facilitates ventilation of the fishery breeding shed, making the ventilation efficient and effective.

[0036] Specifically, a roller shutter shaft 30 is provided at the top of the rear wall 3, and a plurality of sunshades 31 are fixedly connected to the outer wall of the roller shutter shaft 30. One end of the roller shutter shaft 30 is connected to a fourth motor 32, and the roller shutter shaft 30 is driven to rotate by the output end of the fourth motor 32. The roller shutter shaft 30 drives the sunshades 31 to roll onto the roller shutter shaft 30, or stretch to cover the shed film 1, thereby changing the light and temperature in the fishery breeding shed.

[0037] The working process of the present invention is as follows: during the day when there is sunlight, the sunshade 31 is rolled up by the fourth motor 32, and the interior of the fish farming shed is heated by sunlight. When the temperature inside the farming shed is too high, the second motor 23 of the lifting mechanism drives the pressure rod 20 to rise, raising the shed film 1 at the bottom front of the farming shed, and the third motor 28 is started to drive the ventilation fan 6 to work, so that the air with lower temperature outside the farming shed enters the inside of the farming shed through the front vent 4, and then blows out through the two side vents 5, thereby accelerating the speed of air circulation in the farming shed. During ventilation, the first motor 10 of the angle adjustment mechanism drives the screw 14 to rotate, thereby driving the lifting plate 17 to rise and fall, and then changing the angle of the guide plate 7, thereby changing the air inlet angle at the front vent 4.

[0038] The utility model adopts the method of cooperating the front vent 4 and the two side vents 5 for ventilation, and the ventilation efficiency is high. By arranging the angle adjustment mechanism at the front vent 4, it is convenient to adjust the wind direction to the appropriate air inlet angle, so that the ventilation in all directions of the breeding shed body is more uniform, the air circulation speed in the breeding shed body is fast, and the ventilation efficiency is high. At the same time, it avoids the fixed air inlet angle causing the external cold air to blow directly to the same position, so that the temperature in various places in the breeding shed body is relatively balanced, which is conducive to maintaining a suitable breeding environment.

[0039] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
