Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse temperature regulation devices, and in particular to a temperature regulation device for greenhouses in desert areas. Background Technology

[0002] Desert regions typically have extreme climatic conditions, such as high temperatures and large diurnal temperature variations. These characteristics place special demands on the construction and operation of greenhouses.

[0003] When conducting agricultural planting in desert regions, greenhouses need to provide a relatively stable growing environment. This requires greenhouses to have effective temperature regulation capabilities to adapt to the climate characteristics of desert areas. Specifically, greenhouses need to be able to accumulate heat during the day to increase the air and ground temperatures inside the facility; and at night, they need to reduce heat loss to maintain a stable temperature inside the facility.

[0004] In extreme climatic conditions such as large diurnal temperature differences and strong solar radiation, it is difficult to control the internal temperature of greenhouses, which leads to problems such as hindered crop growth and increased energy consumption. In view of this, a temperature regulation device for greenhouses in desert areas is provided. Utility Model Content

[0005] The main purpose of this utility model is to provide a temperature regulation device for greenhouses in desert areas, in order to solve the problems mentioned in related technologies, such as the difficulty in controlling the internal temperature of greenhouses under extreme climatic conditions such as large diurnal temperature differences and strong solar radiation, which lead to the obstruction of crop growth and increased energy consumption.

[0006] To achieve the above objectives, according to one aspect of the present invention, a temperature regulation device for a greenhouse in a desert area is provided, comprising a greenhouse frame, a groove provided in the greenhouse frame, an elastic sealing frame fixedly provided at the center of the groove, air-filled bags for heat insulation fixedly provided on both sides of the elastic sealing frame, a sunshade board for partial sun shading provided above the greenhouse frame, and a pipe for circulating water buried in the desert at the bottom of the greenhouse frame.

[0007] Furthermore, the inflatable bag includes a first inflatable bag and a second inflatable bag, with the first inflatable bag located near the outer side of the greenhouse frame and the second inflatable bag located near the inner side of the greenhouse frame.

[0008] Furthermore, the first inflation bag is filled with nitrogen, and the second inflation bag is filled with argon.

[0009] Furthermore, the elastic sealing frame is mesh-shaped and is used to press and fix the first and second inflatable bags against the sidewall of the groove.

[0010] Furthermore, a solar panel is fixedly installed on the top of the sunshade, and connecting rods are fixedly installed at both ends of the sunshade. Symmetrically arranged fixing blocks are fixedly installed on the ground surface. The fixing blocks are U-shaped, and one end of the connecting rod is rotatably installed inside the fixing block, passing through the side wall of the fixing block and threaded with a screw.

[0011] Furthermore, a roller shutter door is fixedly installed at one end of the greenhouse frame, and a fan for promoting air circulation is fixedly installed at the other end of the greenhouse frame.

[0012] Furthermore, the pipe is S-shaped, and one side of the pipe is fixedly installed in the water tank.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this temperature regulation device for a greenhouse in desert areas, double-layered air bags are installed inside the greenhouse frame and fixed by an elastic sealing frame. The double-layered air bag design provides an additional insulation layer for the greenhouse, effectively blocking the direct impact of high or low external temperatures on the interior of the greenhouse. By adjusting the amount of gas in the air bags, the degree of inflation and insulation performance of the air bags can be changed, thereby achieving precise regulation of the internal temperature of the greenhouse. During the high-temperature period of the day, increasing the inflation amount can improve the insulation effect; while at night or during the lower-temperature period, the inflation amount can be appropriately reduced to maintain the stability of the internal temperature of the greenhouse.

[0015] 2. This temperature regulation device for greenhouses in desert areas includes a shading panel that can be rotated and adjusted according to the sun's position and shading needs, thereby minimizing the area exposed to direct sunlight. This flexibility ensures maximum shading effect, helps reduce the temperature inside the greenhouse and decrease light intensity, and the circulating water pipes can more effectively absorb or release heat, thus regulating the temperature inside the greenhouse.

[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0032] Please see Figures 1-10 As shown, the purpose of this embodiment is to provide a temperature regulation device for a greenhouse in a desert area, including a greenhouse frame 1, a groove 11 is provided in the greenhouse frame 1, an elastic sealing frame 12 is fixedly installed at the center of the groove 11, and air-filled bags for heat insulation are fixedly installed on both sides of the elastic sealing frame 12. A sunshade board 2 for partial sun shading is provided above the greenhouse frame 1, and a pipe 31 for circulating water is buried in the desert at the bottom of the greenhouse frame 1.

[0033] The air bag includes a first air bag 13 and a second air bag 14. The first air bag 13 is located near the outside of the greenhouse frame 1 and can effectively block the direct impact of high or low temperatures on the inside of the greenhouse. The second air bag 14 is located near the inside of the greenhouse frame 1 and can further enhance the temperature stability inside the greenhouse. At night or during periods of low temperature, the second air bag 14 can reduce the loss of heat inside the greenhouse and maintain the stability of the temperature inside the greenhouse.

[0034] The first inflation bag 13 is filled with nitrogen. Nitrogen has a relatively low thermal conductivity, which effectively blocks the transfer of external heat. When the outside temperature rises, the nitrogen in the first inflation bag 13 reduces the transfer of heat from the outside of the greenhouse to the inside, thus playing a role in heat insulation and cooling. The second inflation bag 14 is filled with argon. Compared with nitrogen, argon has an even lower thermal conductivity. Therefore, the second inflation bag 14 provides additional heat insulation while further reducing heat loss from the inside of the greenhouse. At night or during periods of lower temperature, the low thermal conductivity of argon is particularly crucial, helping the greenhouse maintain a stable internal temperature and reduce heat loss.

[0035] By adjusting the amount of nitrogen and argon gas inside the inflatable bag, the degree of inflation and its insulation performance can be altered. During the hottest part of the daytime, increasing the inflation volume makes the bag fuller, improving insulation; while at night or during cooler periods, the inflation volume can be reduced to maintain the stability of the temperature inside the greenhouse.

[0036] Through the synergistic effect of the first air bag 13 and the second air bag 14, the greenhouse can more effectively resist the influence of external temperature fluctuations, providing crops with a more stable and suitable growing environment. At the same time, this double-layer air bag design also increases the overall stability and durability of the greenhouse structure.

[0037] The elastic sealing frame 12 is grid-shaped and made of elastic material, such as rubber or elastic plastic, which has good elasticity and resilience. It can deform when subjected to external force and quickly return to its original shape after the external force is removed. This allows the elastic sealing frame 12 to adapt to grooves 11 of different shapes and sizes, as well as the expansion state of the inflatable bags under different pressures. The elastic sealing frame 12 is used to press and fix the first inflatable bag 13 and the second inflatable bag 14 against the side wall of the groove 11, thereby achieving effective support and positioning of the two inflatable bags and ensuring the stability of the inflatable bags in the groove 11.

[0038] Furthermore, the outer side of the greenhouse frame 1 is covered with a plastic film, usually made of polyethylene, which has good light transmittance, weather resistance and mechanical strength, and can meet the greenhouse's requirements for light, temperature and mechanical stability.

[0039] The sunshade 2 is arc-shaped, and a solar panel is fixedly installed on the top of the sunshade 2, making full use of the abundant solar energy resources in the desert area. Both ends of the sunshade 2 are fixedly installed with connecting rods 21, and symmetrically arranged fixing blocks 22 are fixedly installed on the ground. The fixing blocks 22 are U-shaped, and one end of the connecting rod 21 is rotatably installed in the fixing block 22, allowing the sunshade 2 to be rotated and adjusted within a certain range to adapt to the changes in the sun's position at different times and ensure the maximum sunshade effect. A screw 23 is threaded through the side wall of the fixing block 22 and is used to tighten and fix the connecting rod 21.

[0040] Under intense sunlight, direct sunlight can create high-temperature areas on the greenhouse frame 1. To reduce the temperature in these areas, operators can adjust the angle of the shading panel 2 by rotating it, depending on the sun's position and shading needs. This reduces the area exposed to direct sunlight, and the reflected and scattered light from the shading panel 2 provides more uniform lighting conditions for the crops inside the greenhouse.

[0041] A roller shutter door 5 is fixedly installed at one end of the greenhouse frame 1, which can be flexibly rolled up or lowered to both sides. A fan 4 for promoting air circulation is fixedly installed at the other end of the greenhouse frame 1. In the hot summer or during high-temperature periods, the temperature inside the greenhouse may rise sharply, which will have an adverse effect on crop growth. At this time, by turning on the fan 4 and rolling up the roller shutter door 5, the air exchange between the inside and outside of the greenhouse can be accelerated, the hot air inside the greenhouse can be exhausted, and the cooler air from the outside can be introduced, thereby effectively reducing the temperature inside the greenhouse.

[0042] The S-shaped pipe 31 enhances the heat exchange efficiency between the water and the soil. The S-shaped pipe 31 increases the flow path of water in the soil, allowing the water to absorb or release heat more fully, thus more effectively regulating the temperature inside the greenhouse. One side of the pipe 31 is fixedly connected to the water tank 3. The inlet 311 of the pipe 31 is connected to the outlet of the water tank 3, and the outlet 312 of the pipe 31 is connected to the inlet of the water tank 3, forming a complete closed-loop water circuit. This ensures continuous circulation of the water. During the day, the desert surface temperature rises due to sunlight, causing the water temperature in the pipe 31 to rise accordingly. At night, the desert temperature drops rapidly, causing the water temperature in the pipe 31 to drop accordingly. This provides a stable and continuous heat or cold source for temperature regulation inside the greenhouse, thus more effectively regulating the temperature. A water pump installed inside the water tank 3 provides the power for the water circulation.

[0043] In practical use, this invention adjusts the inflation level and heat insulation performance of the air bag by changing the amount of nitrogen and argon gas inside the air bag according to the requirements of the outside temperature and the temperature inside the greenhouse. The elastic sealing frame 12 fixes the air bag to the side wall of the groove 11. The angle of the sunshade 2 is adjusted by rotating it according to the position of the sun and the shading requirements. The angle of the connecting rod 21 is fixed by tightening the screw 23, thereby fixing the position of the sunshade 2. When the temperature inside the greenhouse rises sharply, the fan 4 is turned on and the roller shutter door 5 is rolled up to accelerate the air exchange between the inside and outside of the greenhouse and reduce the temperature inside the greenhouse.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
