Description

Technical Field

[0001] This utility model relates to a water-circulating, heat-storing, double-slope solar greenhouse, and pertains to the field of facility horticulture technology. Background Technology

[0002] Solar greenhouses are a major type of production facility in northern my country during the autumn and winter seasons, offering advantages such as high efficiency and energy saving. However, traditional thick-walled greenhouses occupy a large area and have low land utilization; brick-walled solar greenhouses have high construction costs and low construction efficiency. In recent years, flexible-walled solar greenhouses have been rapidly promoted due to their ease of construction and high land utilization, but their heat storage capacity is limited and cannot meet the needs of crop overwintering production. To address these issues, this utility model proposes a water-source heat storage and release type double-slope flexible-walled solar greenhouse. Utility Model Content

[0003] The purpose of this invention is to design a water-circulating, heat-storing, double-slope solar greenhouse that can improve the heat storage capacity of a greenhouse.

[0004] This utility model includes the main body of the south greenhouse and the north greenhouse, and the rear wall between them. A group of east-west oriented hot water collecting bags are arranged on the south side of the rear wall. A hot water collecting tank is set below the hot water collecting bags. A circulating water pump is set on one side of the hot water collecting tank. The outlet of the circulating water pump is connected to the inlet pipe. The inlet pipe passes through the upper part of each hot water collecting bag in sequence. The part of the inlet pipe inside each hot water collecting bag is provided with an inlet. A return water port is set at the lower end of each hot water collecting bag. Each return water port is connected to a return water pipe. At least a part of the hot water collecting bags is set below the ground in the hot water collecting tank. The return water pipe is connected to the hot water collecting tank.

[0005] Furthermore, the hot water collecting bags are longitudinally distributed along the south surface of the rear wall and are flat in shape. This design increases the contact time between the water flow and the collecting bags, thus improving the heating effect on the water.

[0006] Furthermore, hot water bottles are hung on the back wall.

[0007] Furthermore, the hot water collection tank includes a tank body located below ground level and a cover plate covering its upper port. The hot water collection tank with the above design can improve its heat preservation effect.

[0008] Furthermore, windbreaks are installed on the east and west sides of the main greenhouse roof, with retractable insulation blankets placed between the windbreaks. These windbreaks effectively block side winds, preventing strong winds from blowing the insulation blankets away and improving insulation performance.

[0009] Furthermore, the windbreak includes an outer upright and an inner diagonal brace, which are integrally formed and connected at the upper end. An insulation layer is attached to the outer surface of the windbreak. This design improves the stability of the windbreak.

[0010] This utility model consists of two connected greenhouses, one in the north and one in the south, presenting a double-slope structure, increasing the north-south span, improving land utilization, and enhancing the heat preservation effect of the south greenhouse.

[0011] This invention employs a flexible hollow insulation wall to enhance its insulation performance, reduce the floor space required, and improve land utilization. A hot water collection bag is installed in the south-facing greenhouse. During the day, when the insulation blanket is rolled up, sunlight shines on the hot water collection bag, and water is transported to a hot water tank for storage. At night, when the insulation blanket is lowered, water from the hot water tank is sent to the hot water collection bag to dissipate heat and increase the greenhouse's temperature, thereby enhancing the greenhouse's daytime heat storage capacity and preventing low nighttime temperatures from harming crops.

[0012] In this invention, a windbreak is installed at the top of the side wall of the greenhouse, which can protect the insulation blanket, prevent strong winds from blowing the insulation blanket, reduce wind damage, and improve the insulation effect. Attached Figure Description

[0014] by Figure 1 The diagram defines the up, down, left, right, front, and back directions in this embodiment. Figure 1 The left-right direction is defined as the north-south direction in this embodiment, and the front-back direction is defined as the east-west direction.

[0015] As shown in the figure, this embodiment includes a greenhouse body consisting of a south greenhouse 1 and a north greenhouse 2. The south greenhouse 1 includes a set of south slope frames 3 arranged longitudinally in an east-west direction. A set of north slope frames 4, corresponding to the south slope frames 3, is located to the right of the south slope frames 3. In this embodiment, both the south slope frames 3 and the north slope frames 4 are steel frame structures, constructed from elliptical steel pipes measuring 75*30*3.0mm. The longitudinal spacing between each frame is 1m, and both are covered with a plastic film 7. A rear wall 5 is provided between the south greenhouse 1 and the north greenhouse 2. The adjacent ends of the south slope frames 3 and the north slope frames 4 are fixedly connected to the upper surface of the rear wall 5. In this embodiment, the rear wall 5 is a steel truss structure, and the outer perimeter of the steel frame is covered with a plastic film and thermal insulation material, separating the north and south greenhouses. The rear wall 5 has side walls 6 at both the east and west ends. The side walls 6 are matched with the shape of the south slope frame 3 to the north slope frame 4. They adopt a structure with a steel truss covered with plastic film and thermal insulation material. The lower end is fixed to the ground. A groove is opened at the connection with the rear wall 5 so that the east and west ends of the rear wall 5 are embedded in the side walls 6, which improves the stability of the greenhouse.

[0016] Windbreaks 9 are installed on the east and west sides of the main greenhouse roof. A retractable insulation blanket 8 is installed between the windbreaks 9 on both sides. The insulation blanket 8 is sized to match the roof of the main greenhouse. The middle part is fixedly connected to the dividing point of the south and north slope frames, while the remaining part is rolled up on the north and south slopes. During the day, the insulation blanket 8 on the north and south slopes can be rolled up to allow sunlight to irradiate and store heat in the greenhouse. At night, the insulation blanket 8 is lowered for heat preservation. In this embodiment, the windbreak 9 includes an outer upright 16 and an inner diagonal 17. The upright 16 and diagonal 17 are integral and connected at the upper end. The lower ends of the two stalks are fixedly connected to the side wall 6, and an insulation layer 18 is attached to the outer surface. The windbreak 9 extends from the south base of the two side walls 6 to the north base. When the insulation blanket 8 is lowered, the windbreak 9 can block lateral winds, preventing strong winds from blowing the insulation blanket and improving the heat preservation effect.

[0017] A set of hot water collecting bags 10 arranged in an east-west direction along the south side of the rear wall 5 is installed. The hot water collecting bags 10 are flat along the south surface of the rear wall 5, made of black, lightweight, thin water bags, with an opening at the top, and are hung on the rear wall 5 by adhesive. A hot water collecting tank 11 is installed below the hot water collecting bags 10. The tank body of the hot water collecting tank 11 is located below the ground, and a cover plate 15 covering its upper port is installed on top. A circulating water pump 14 is installed at the front of the hot water collecting tank 11. The outlet of the circulating water pump 14 is connected to a water inlet pipe 12. The water inlet pipe 12 is fixedly connected to the rear wall 5 and extends along its south surface, passing through the upper opening of each hot water collecting bag 10 in sequence. The part of the water inlet pipe 12 inside each hot water collecting bag 10 is provided with a water inlet. When in use, the circulating water pump is started, and water can be added to the hot water collecting bags 10 through the water inlet pipe 12. Each hot water collection bag 10 has a return water inlet at its lower end, and each return water inlet is connected to a return water pipe 13. The return water pipe 13 extends downward and connects to the hot water collection tank 11, which can transport the water from each hot water collection bag 11 to the hot water collection tank to achieve water circulation.

[0018] In this embodiment, the span of the south greenhouse 1 is 14-16m and the height is 6-7m, while the span of the north greenhouse is 6-8m and the height is 4-5m. As mentioned above, the span of the south greenhouse 1 is larger than that of the north greenhouse 2 to ensure sufficient sunlight exposure on the south-facing side. The thermal insulation material and insulation blanket 8 covering the outer perimeter of the rear wall 5 and side walls 6 are both 40mm thick to ensure the insulation effect of the greenhouse.

[0019] In this embodiment, during the day, the insulation blanket 8 needs to be rolled up to allow sunlight to irradiate the inside of the greenhouse. The circulating water pump 14 sends water from the hot water collection tank 11 into the hot water collection bag 10 through the inlet pipe 12. The water flows slowly down the inner wall of the hot water collection bag 10 through the inlet. Due to the small flow rate, the water in the hot water collection bag 10 heats up rapidly and then flows back to the hot water collection tank 11 through the return pipe 13, thus circulating and heating the water in the hot water collection tank 11. At night, after the insulation blanket 8 is lowered, when the temperature inside the south greenhouse is lower than the water temperature, the water circulating to the hot water collection bag 10 exchanges heat with the greenhouse air, releasing heat and warming the greenhouse.
