Description

Technical Field

[0001] This utility model belongs to the field of agricultural facility engineering, specifically relating to a water circulation heat storage and insulation wall device for a solar greenhouse. Background Technology

[0002] Solar greenhouses are crucial facilities for winter vegetable cultivation in northern my country, but their large diurnal temperature range and rapid heat loss at night can negatively impact crop growth. Existing greenhouse insulation and heat storage technologies primarily utilize soil walls and phase change materials, which suffer from low heat storage efficiency, high costs, and unstable temperature release. Therefore, there is an urgent need for a highly efficient and economical heat storage and insulation device to achieve stable diurnal temperature control in solar greenhouses.

[0003] However, it was found during use that the existing greenhouse walls had poor insulation, causing the temperature inside the greenhouse to drop at night, resulting in low-temperature damage and seriously affecting crop yield and quality. Utility Model Content

[0004] This invention aims to solve the problems of insufficient nighttime heat preservation and large temperature difference between day and night in existing solar greenhouses, and provides a water-circulating heat storage and heat preservation wall device that achieves efficient temperature control of the greenhouse by utilizing the heat storage and heat release characteristics of water.

[0005] The technical solution of this utility model is as follows: This utility model is a water-circulating heat storage and insulation wall device for a solar greenhouse. Its special feature is that the water-circulating heat storage and insulation wall device for a solar greenhouse includes a fixed support, multiple water storage units, and a water circulation system. The multiple water storage units are respectively mounted on the fixed support, which is used to fix the water storage units to the greenhouse wall area to ensure structural stability. Each water storage unit includes an internal box for storing water, with an inlet at the top and an outlet at the bottom. The water circulation system includes an inlet pipe and an outlet pipe. The inlet pipe is connected to the inlet of each water storage unit via branch pipes, and the outlet pipe is connected to the outlet of each water storage unit via branch pipes, realizing the circulation or replenishment of water within the water storage unit.

[0006] Furthermore, multiple water storage units are arranged in a matrix and assembled into a wall structure through fixed supports, forming the main heat storage component of the wall.

[0007] Furthermore, the inner surface of the box is equipped with reinforcing ribs to enhance the structural strength of the module and prevent deformation after water is stored.

[0008] Furthermore, the fixed bracket is provided with a positioning groove that matches the water storage unit. The water storage unit is mounted on the fixed bracket through the positioning groove, which facilitates the quick installation and positioning of the water storage unit.

[0009] Furthermore, the water circulation system also includes a circulation pump, which is installed on the inlet or outlet pipe.

[0010] Furthermore, the water circulation system also includes two temperature sensors: one temperature sensor is installed inside the water storage unit, and the other temperature sensor is installed inside the greenhouse. The temperature sensors enable automatic monitoring of the water temperature and the temperature inside the greenhouse.

[0011] Furthermore, the water circulation system also includes a controller, which is installed inside the greenhouse and connected to the temperature sensor and the circulation pump, respectively. The controller enables intelligent control of the water circulation.

[0012] Furthermore, the box is made of weather-resistant plastic.

[0013] Furthermore, the fixing bracket is made of metal or high-strength plastic.

[0023] The overall scheme of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0024] See Figure 1 —3. The structure of this utility model embodiment includes a fixed support 3, multiple water storage units 1, and a water circulation system 2. The multiple water storage units 1 are respectively mounted on the fixed support 3 and arranged in a matrix. They are assembled into a wall structure through the fixed support 3 to form the heat storage body of the wall. The water storage unit 1 includes a hollow box made of HDPE (high-density polyethylene) material. The inside of the box is a water storage cavity. The inner surface of the box is provided with reinforcing ribs 8 to enhance the structural strength. Each water storage unit 1 has a water inlet 6 at the top and a water outlet 7 at the bottom. The water circulation system 2 includes an inlet pipe 4, an outlet pipe 5, and a circulation pump 9. The inlet pipe 4 is connected to the inlet 6 of each water storage unit 1 through a branch pipe. The outlet pipe 5 is connected to the outlet 7 of each water storage unit 1 through a branch pipe. The circulation pump 9 is used to drive the water to circulate in the system (it can also circulate naturally by utilizing the temperature difference of the water). The fixed bracket 3 is used to fix the water storage unit 1 to the greenhouse wall area to ensure structural stability. The fixed bracket 3 is a frame structure welded from galvanized steel pipes. The frame is provided with a positioning groove 10 that matches the water storage unit 1. After the water storage unit 1 is embedded in the positioning groove 10, it is fixed by bolts.

[0025] Temperature sensor 11 needs to monitor both the water temperature inside water storage unit 1 and the air temperature inside the greenhouse simultaneously. Specifically, it is located in two places:

[0026] First location: Inside the water storage unit 1: The temperature sensor 11 is placed in the water inside the water storage unit 1 through the reserved interface (or pre-embedded during the production of the water storage unit 1) to directly collect the real-time temperature of the water medium. This is the core basis for determining whether water circulation needs to be started.

[0027] Air layer near the greenhouse wall: Fix another temperature sensor 11 to the outside of the water storage unit 1 (on the side closer to the inside of the greenhouse), or install it on a bracket near the greenhouse wall to monitor the air temperature inside the greenhouse at night and help determine whether heat needs to be replenished through water circulation.

[0028] The controller is wall-mounted. The greenhouse has a dedicated equipment control room, and the controller is directly installed on the wall of the control room for easy data viewing and manual parameter adjustment by staff. The controller is connected to temperature sensor 11 and circulation pump 9.

[0029] In this embodiment, the number of water storage units 1 can be adjusted according to the length and height of the greenhouse. A temperature sensor 11 and a controller can be added to the water circulation system 2. When the water temperature is lower than the set value, the circulation pump 9 is started to replenish water, so as to realize intelligent temperature control.

[0030] In operation, the water storage unit 1 is first fixed to the greenhouse wall area using a fixing bracket 3. Water is then pumped into each water storage unit 1 through the inlet pipe 4 using a water pump. During the day, the greenhouse receives sunlight, and the water in the water storage unit 1 absorbs heat, causing its temperature to rise. At night, the internal temperature of the greenhouse decreases, and the hot water in the water storage unit 1 releases heat, raising the internal temperature of the greenhouse. When the water temperature fluctuates due to long-term heat storage and release, water can be replenished or replaced through the water circulation system 2 to ensure the heat storage effect.

[0031] The content of this utility model and the technical content not specifically described in the above embodiments are the same as the prior art.

[0032] The above are merely specific embodiments disclosed in this utility model, but the scope of protection disclosed in this utility model is not limited thereto. The scope of protection disclosed in this utility model shall be determined by the scope of protection of the claims.
