Description

Technical Field

[0001] The utility model relates to the technical field of greenhouses, and in particular to a solar heat collecting plate and a heat storage and temperature regulating greenhouse. Background Art

[0002] Greenhouses are generally composed of enclosing walls on both sides, a rear wall at the back, a supporting frame and covering materials covering the supporting frame. They are important agricultural facilities in the northern region. The covering materials covering the supporting frame are often made of transparent plastic film, which mainly provides a suitable temperature and humidity environment for crops in the autumn and winter seasons, increases the yield of crops, and enables the northern region to obtain fresh fruits and vegetables in the autumn and winter seasons.

[0003] Some greenhouses are equipped with solar collectors on the top, and hot water is introduced into the greenhouse through water pipes. The heat stored in the hot water is released into the greenhouse through heat pipes to increase the temperature of the greenhouse. The temperature inside the greenhouse can be increased at night in autumn and winter or in severe cold weather. However, when the temperature is high during the day, the greenhouse itself needs to be ventilated or closed. The hot water in the solar collector releases heat, which will accelerate the loss of moisture in the crops and increase the probability of wilting and drying of the crops. The utilization rate of the solar collector installed in the upper space of the greenhouse is low, and the use effect is not good.

[0004] In addition, some greenhouses often use heating equipment such as heating furnaces or electric heaters to increase the temperature inside the greenhouse during the nights of autumn and winter or when the temperature inside the greenhouse is low in severe cold weather. When the temperature inside the greenhouse is high during the day, in order to prevent the loss of moisture inside the crops and increase the probability of wilting and drying of crops, the greenhouse is often required to be ventilated and cooled. Ventilation and cooling during the day causes the heat collected in the greenhouse to be dissipated, and the use of heating equipment to heat the greenhouse during the nights of autumn and winter or in severe cold weather consumes a lot of energy.

[0005] Therefore, there is an urgent need for a solar collector that can assist in regulating the temperature inside the greenhouse and improve the utilization rate of the solar collector, as well as a heat storage and temperature-regulating greenhouse with multiple heat storage modes that can heat up the greenhouse and save energy when the temperature inside the greenhouse is low. This is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0045] This embodiment provides a solar thermal collector panel. Figures 1 to 12 , including a plurality of adjacently arranged heat collecting panel units 3-1, referring to Figures 2 to 7 The heat collecting plate unit 3-1 is obliquely arranged at the front end of the temperature regulating water wall 2, and the heat collecting plate unit 3-1 is supported on a support rod. The heat collecting plate unit 3-1 is arranged in the upper space of the temperature regulating water wall 2, and the side walls of the adjacent heat collecting plate units 3-1 are fitted together to improve the space utilization rate of the heat collecting plate unit 3-1.

[0046] Compared with the existing solar collector panels arranged on the outside of the greenhouse, the solar collector panels of the present application are arranged in the inner space of the greenhouse, which has a good warming effect at night in autumn and winter or during severe cold weather.

[0047] When the temperature in the greenhouse is high during the day, the solar collector panel 3 fully absorbs the heat of the solar energy and stores it in the heat-collecting water. The solar collector panel also absorbs the heat inside the greenhouse by heat conduction, and heats the heat-collecting water in the solar collector panel 3, thereby reducing the temperature of the upper space in the greenhouse, thereby promoting air circulation in the greenhouse and reducing the temperature of the environment around the crops. There is no need to ventilate and dissipate heat in the greenhouse, thereby improving the utilization efficiency of the solar collector panel. When the temperature in the greenhouse is low at night or in severe cold weather, the heat-collecting water in the solar collector panel releases heat to assist in raising the temperature in the greenhouse, and using heating equipment or electric heating to heat the greenhouse saves energy.

When the temperature in the greenhouse is high, the temperature in the greenhouse is lowered and the heat is stored in the heat collecting water in the water collecting and heating chamber 3-6. When the temperature in the greenhouse is low at night or in severe cold weather, the heat collecting water in the water collecting and heating chamber 3-6 releases heat to help increase the temperature in the greenhouse, promote crop growth, and save energy. The water collecting and heating chamber 3-6 is configured as a long hole-type blow-molded extruded hollow plate, and the water collecting and heating chamber 3-6 is configured as a cavity structure with open ends.

When the temperature in the greenhouse is high during the day, there is no need to frequently ventilate and dissipate heat in the greenhouse. When the temperature in the greenhouse is low at night or in severe cold weather, the heat-collecting water in the internal space of the water collecting and heating chamber 3-6 releases heat to assist in increasing the temperature of the greenhouse; the solar collector panel 3 assists in regulating the temperature in the greenhouse, and the temperature in the greenhouse can be reduced without ventilating and dissipating the greenhouse, and the heat in the greenhouse can be stored in the heat-collecting water in the water collecting and heating chamber 3-6; at night or in severe cold weather, the heat-collecting water in the water collecting and heating chamber 3-6 releases heat to assist in increasing the temperature in the greenhouse. When the temperature in the greenhouse is low, the greenhouse can be heated up to save energy.

The first water return pipe 3-3 is connected with the second water outlet pipe 2-5, and the heat-collecting water in the temperature-adjusting water wall 2 is introduced into the solar heat collecting panel 3 through the circulating water pump 4. The first water outlet pipe 3-2 is connected with the second water return pipe 2-2, and the water heated by the solar heat collecting panel 3 circulates to the second water return pipe 2-2; the second water outlet pipe 2-5 is connected with the lower space of the temperature-adjusting water wall 2, and the second water return pipe 2-2 is connected with the upper space of the temperature-adjusting water wall 2, so that the heat-collecting water in the temperature-adjusting water wall 2 and the solar heat collecting panel 3 circulates, and has a variety of heat storage modes, which makes the temperature in the greenhouse maintained within a stable temperature range, so that the greenhouse has a good thermal insulation effect.
