Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting greenhouses, in particular to a constant temperature device for greenhouses. Background Art

[0002] A greenhouse is a covered agricultural facility used to grow vegetables, fruits and other crops. A greenhouse is usually made of materials such as metal frames and plastic films to form an enclosed space. The temperature, humidity, light and other environmental factors can be controlled inside the greenhouse to provide good growth conditions for crops. Greenhouse planting is widely used in modern agriculture and can improve crop yield, quality and stress resistance. It is an efficient planting method. When the greenhouse is used to grow and cultivate agricultural fruits and vegetables, the fruits and vegetables in the greenhouse are easily affected by the external environment. If the temperature is not reached or the temperature is too high or too low, it will cause certain damage to the fruits and vegetables in the greenhouse. In hot weather, the temperature in the greenhouse will be higher than the external environment. If the temperature is too high, it is easy to cause damage to the fruits and vegetables in the greenhouse. In cold weather, the temperature in the greenhouse is too low, which will also cause certain damage to the fruits and vegetables in the greenhouse. At the same time, in blizzard weather, snow accumulates on the roof surface of the greenhouse. On the one hand, it will cause load-bearing pressure on the greenhouse, which will cause deformation at the lightest and collapse and damage at the worst. On the other hand, the snow covering the surface of the greenhouse will also have a certain impact on the temperature inside the greenhouse, thereby reducing the use effect of the greenhouse and affecting the growth efficiency and quality of fruits and vegetables planted inside the greenhouse.

[0003] Therefore, it is necessary to develop a constant temperature device for greenhouse. Utility Model Content

The three sets of ventilation fans 202 on the ventilation box 2 are used to ventilate the interior of the greenhouse 1, so as to maintain the internal air circulation of the greenhouse 1. The heating wire 205 is installed inside the ventilation box 2, and the heating wire 205 is energized. The heat generated by the energized heating wire 205, combined with the ventilation fan 202, can effectively heat the internal temperature of the greenhouse 1. According to the internal temperature of the greenhouse 1, the ventilation fan 202 and the heating wire 205 can be started if the temperature is too low, so as to achieve the effect of heating the interior of the greenhouse 1. If the temperature is too high, the heating wire 205 can be turned off. Constant temperature components 3 are installed on both sides of the top of the greenhouse 1.

[0025] The thermostatic assembly 3 includes a bearing frame 301, a support frame 302 is installed on the upper part of the bearing frame 301, and a protective pad 303 is arranged on the upper surface of the support frame 302. The bearing frame 301 is provided in two groups, and a motor 304 is installed on the upper rear end surface of one group of bearing frames 301. The output shaft on the motor 304 is fixedly connected to one end of the rotating shaft 305 through a coupling, so that the motor 304 can drive and control the rotating shaft 305 to rotate forward or reverse. A sunshade 306 is installed on the outer wall of the rotating shaft 305, and the upper surface of the sunshade 306 A mounting groove 307 is provided at the center of the surface, and a solar panel 308 is installed inside the mounting groove 307. A sunshade 306 is installed on the outer wall of the rotating shaft 305, and a support frame 302 is installed correspondingly between the bearing frames 301 on the opposite sides, so that when the motor 304 drives the sunshade 306 to fold to the left or right, the support frame 302 can support it in parallel, and the rotating shaft 305 is prevented from being deformed due to excessive force. When the greenhouse 1 encounters hot weather, the motor 304 drives the left and right directions The sunshades 306 are connected to each other, which can provide shade for the top of the greenhouse 1, and try to avoid the high temperature inside the greenhouse 1 caused by the hot external environment, while also keeping the temperature inside the greenhouse 1 from rising. Together with the ventilation fan 202, the interior of the greenhouse 1 can be effectively kept at a constant temperature. In heavy snow, the sunshades 306 in the connected state can be used for protection and isolation. When there is too much snow, the motor 304 only needs to drive the sunshades 306 to be in a tilted state, which can effectively slide and eliminate the snow accumulated on the surface of the sunshades 306.

[0026] Working principle: When using the utility model, multiple sets of ventilation boxes 2 are installed by the mounting frame 201 according to the ventilation needs of the greenhouse 1. The three sets of ventilation fans 202 on the ventilation box 2 are used to ventilate the inside of the greenhouse 1 to maintain the internal air circulation of the greenhouse 1. The heating wire 205 is installed inside the ventilation box 2 and the heating wire 205 is energized. The heat generated by the energized heating wire 205, in combination with the ventilation fan 202, can effectively heat the internal temperature of the greenhouse 1. According to the internal temperature of the greenhouse 1, the ventilation fan 202 can be started when the temperature is too low. The heating wire 205 is used to increase the temperature inside the greenhouse 1. If the temperature is too high, the heating wire 205 can be turned off. The four bearing frames 301 on the thermostatic component 3 are installed on the top of the greenhouse 1 in two opposite directions, and the output shaft of the motor 304 on the rear end surface of one set of bearing frames 301 is installed with the shaft 305 by a coupling, so that the motor 304 can drive the shaft 305 to rotate forward or reverse. The sunshade 306 is installed on the outer wall of the shaft 305, and the support frame 302 is installed between the bearing frames 301 on the opposite sides. When the motor 304 drives the sunshade 306 to fold to the left or right, the sunshade 306 can be turned left or right. The support frame 302 is supported in parallel to avoid deformation of the rotating shaft 305 caused by excessive force. When the greenhouse 1 encounters hot weather, the motor 304 drives the left and right sunshades 306 to connect with each other, which can provide sunshade treatment for the top of the greenhouse 1, and try to avoid the high temperature inside the greenhouse 1 caused by the external hot environment. At the same time, it also keeps the temperature inside the greenhouse 1 from rising. With the ventilation fan 202, it can effectively keep the inside of the greenhouse 1 at a constant temperature. In heavy snow weather, the sunshades 306 in the docking state can be used for protection and isolation. When there is too much snow, only the motor 30 4 The sun visor 306 is driven in an inclined state, which can effectively slide and eliminate the snow accumulated on the surface of the sun visor 306. On the one hand, it reduces the load-bearing damage of the snow to the greenhouse 1, and on the other hand, it also avoids the situation where the snow has a certain impact on the temperature inside the greenhouse 1. At the same time, the solar panel 308 is paved inside the installation groove 307 on the sun visor 306. In hot weather, the sun visor 306 is closed to facilitate the solar panel 308 to absorb heat energy, thereby taking energy-saving power supply treatment for the equipment in the greenhouse 1, effectively improving the use effect of the constant temperature device used in the greenhouse, and also effectively improving the use effect of the greenhouse.
