Description

Technical Field

[0001] This utility model relates to the field of silkworm shed technology, and more specifically, to an insulated silkworm shed. Background Technology

[0002] Mulberry cultivation and silkworm rearing have a long history in my country. With the development of township industries and the promotion of large-scale breeding, traditional indoor silkworm rearing methods can no longer meet the needs of large-scale breeding. Outdoor sheds for raising large silkworms require less investment, yield higher returns, and can solve the problem of insufficient silkworm rearing area indoors. This effectively saves manpower and resources, improves the economic benefits of silkworm production, and has become the preferred solution for many farmers to expand their breeding scale.

[0003] However, conventional greenhouse silkworm rearing presents a technical challenge: when the temperature inside the greenhouse drops below the optimal 24-25℃ for silkworm rearing during early spring and late autumn, artificial heating is required. While high-powered air conditioners have been installed to address this, meeting the environmental requirements for silkworm rearing, they significantly increase production costs. Alternatively, coal stoves can be used for heating when outdoor temperatures are low. Although this achieves the target temperature and humidity, the enclosed environment can lead to excessively high CO concentrations, potentially causing carbon monoxide poisoning in humans and silkworms, further increasing production costs. Therefore, a more cost-effective, insulated silkworm rearing greenhouse is needed. Utility Model Content

[0004] The purpose of this invention is to provide an insulated silkworm shed that can use different insulation layers to keep the shed warm according to the ambient temperature, thereby reducing production costs and ensuring the quality of silkworm rearing.

[0005] This utility model is achieved through the following technical solution:

[0006] A heat-insulating silkworm shed includes a supporting arch frame, a thin film layer covering the supporting arch frame, and a heat-insulating cover covering the thin film layer; the heat-insulating cover includes a heat-insulating frame, on which a first roller, a second roller, and a third roller are installed, a first heat-insulating layer is wound on the first roller, a second heat-insulating layer is wound on the second roller, and a third heat-insulating layer is wound on the third roller.

[0009] Furthermore, a guide wheel is provided on the outer surface of the thin film layer, and the guide wheel is rotatably connected to the supporting arch.

[0010] Furthermore, the supporting arch frame includes a supporting part and an arc-shaped part, both ends of the arc-shaped part are connected to the supporting part, and a plurality of crossbeams are evenly arranged on the inner wall of the arc-shaped part.

[0011] Furthermore, a humidity sensor and a desiccant are installed on the supporting arch, and the humidity sensor is signal-connected to the desiccant.

[0012] Furthermore, the insulated silkworm shed also includes a blower, which is located inside the supporting arch frame, and the blower's outlet is connected to the outside.

[0013] Furthermore, a first adhesive layer is provided at the unfolded ends of the first, second, and third insulation layers, and a second adhesive layer is provided on the film layer, wherein the first adhesive layer is bonded to the second adhesive layer.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0015] In this invention, the first, second, and third insulation layers can be wound and unwound respectively using the first, second, and third rollers. This allows for the selection of different insulation layers based on the ambient temperature, achieving varying levels of insulation for the silkworm shed and meeting different temperature requirements during silkworm rearing.

[0026] Example 1

[0027] like Figure 1-3 As shown, this embodiment provides a heat-insulating silkworm shed, including a supporting arch frame, a thin film layer 4 covering the supporting arch frame, and a heat-insulating cover covering the thin film layer 4; the heat-insulating cover includes a heat-insulating frame 5, on which a first roller 6, a second roller 7, and a third roller 8 are installed, a first heat-insulating layer 9 is wound on the first roller 6, a second heat-insulating layer 10 is wound on the second roller 7, and a third heat-insulating layer 11 is wound on the third roller 8.

[0028] The first roller 6, the second roller 7, and the third roller 8 can be used to roll up and unroll the first insulation layer 9, the second insulation layer 10, and the third insulation layer 11, respectively. This allows for the selection of different insulation layers based on the ambient temperature, achieving varying levels of insulation for the silkworm shed and meeting the different temperature requirements during silkworm rearing. Furthermore, using insulation covers to keep the silkworm shed warm eliminates the need for additional heating equipment, saving energy and reducing production costs.

[0029] In this embodiment, the first insulation layer 9 is a black and white film layer, the second insulation layer 10 is an insulation cotton layer, and the third insulation layer 11 is a fiberglass wool felt layer. The black film side of the first insulation layer 9 faces outwards. During the day, the black film converts solar energy into heat energy, increasing the temperature of the silkworm shed. At night, the black film prevents heat loss, maintaining the temperature of the silkworm shed and enhancing its insulation effect. The insulation cotton layer effectively blocks heat transfer from the outside air, forming a relatively enclosed space to prevent internal heat loss. It also absorbs and stores heat, reducing heat loss and maintaining a stable internal temperature in the silkworm shed. The air pores in the fiberglass wool felt layer prevent heat transfer, reducing heat conduction paths. It also has a certain radiation and scattering effect, reducing heat penetration and lowering the efficiency of heat radiation transfer, resulting in good insulation. Each insulation layer, used alone or in combination, can achieve different insulation effects, facilitating temperature adjustment of the silkworm shed according to the required temperature for silkworm rearing, making it highly practical.

[0030] In this embodiment, a first motor 12 is connected to the first reel 6, a second motor 13 is connected to the second reel 7, and a third motor 14 is connected to the third reel 8. All motors and reels are connected via belt drives. The first motor 12, second motor 13, and third motor 14 can quickly unfold or rewind the first insulation layer 9, the second insulation layer 10, and the third insulation layer 11, and can also control different insulation layers individually, facilitating the use of different insulation layers to maintain the temperature of the silkworm shed.

[0031] In this embodiment, a guide wheel 15 is provided on the outer surface of the thin film layer 4, and the guide wheel 15 is rotatably connected to the supporting arch frame. The guide wheel 15 is located at the top of the supporting arch frame, allowing a gap to be left between the thin film layer 4 and the insulation layer. When the insulation layer is rolled up, the guide wheel 15 provides a certain guiding force, making it easier to roll up the insulation layer.

[0032] In this embodiment, the supporting arch frame includes a supporting part 2 and an arc-shaped part 1. Both ends of the arc-shaped part 1 are connected to the supporting part 2, and a plurality of crossbeams 3 are evenly arranged on the inner wall of the arc-shaped part 1. The arc-shaped part 1, the supporting part 2, and the crossbeams 3 work together to improve the stability of the supporting arch frame, giving the silkworm shed better stability.

[0033] In this embodiment, a humidity sensor 16 and a dehumidifier 17 are installed on the supporting arch frame, and the humidity sensor 16 is signal-connected to the dehumidifier 17. The humidity sensor 16 can monitor the humidity inside the silkworm shed. When the humidity reaches the preset value of the humidity sensor 16, the humidity sensor 16 sends a signal to the dehumidifier 17, and the dehumidifier 17 absorbs the moisture inside the silkworm shed to prevent excessive humidity from affecting the growth of silkworms.

[0034] In this embodiment, the insulated silkworm shed further includes a fan 18, which is located inside the supporting arch frame, and its outlet is connected to the outside. The fan 18 ensures proper ventilation in the silkworm shed, preventing stagnant air from breeding bacteria and affecting silkworm growth.

[0035] In this embodiment, the unfolded ends of the first insulation layer 9, the second insulation layer 10, and the third insulation layer 11 are all provided with a first adhesive layer 19, and the film layer 4 is provided with a second adhesive layer 20. The first adhesive layer 19 and the second adhesive layer 20 are bonded together. The bonding between the first adhesive layer 19 and the second adhesive layer 20 improves the connection strength between the insulation layer and the film layer 4, preventing the insulation layer from being blown off by strong winds. In other embodiments, the first adhesive layer 19 between the first insulation layer, the second insulation layer, and the third insulation layer can also be bonded and fixed.

[0036] In use, the first motor 12 drives the first roller 6 to rotate, causing the first insulation layer 9 to gradually unfold. The unfolded end of the first insulation layer 9 is manually pulled to cover the surface of the film layer 4, and the first adhesive layer 19 and the second adhesive layer 20 are bonded together to fix the first insulation layer 9, thus insulating the silkworm shed. The second insulation layer 10 and the third insulation layer 11 are used in the same way.

[0037] During winding, the first adhesive layer 19 and the second adhesive layer 20 are separated, and the first motor 12 drives the first roll 6 to rotate, so that the first insulation layer 9 is gradually wound onto the first roll 6. The second insulation layer 10 and the third insulation layer 11 are wound in the same way.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
