[0002] Installing solar photovoltaic panels on the top of the greenhouse can make the greenhouse have the function of power generation, which can make fuller use of solar energy to meet the heating needs inside the greenhouse, increase the temperature of the greenhouse, and promote the rapid growth of crops;

[0003] Under the premise of ensuring the required temperature of the greenhouse, the greenhouse must also be properly ventilated to enable the crops inside to grow better. Exhaust fans are usually used to dissipate the internal heat. In order to ensure the ventilation effect at the front and back ends of the greenhouse, the exhaust fans are spaced on the two side walls of the greenhouse so that ventilation can be carried out everywhere inside. When more exhaust fans are used to meet the ventilation needs, in actual use, multiple sets of exhaust fans are required to work at the same time to ventilate and dissipate the heat inside the greenhouse through exhaust fans, which is inconvenient to use and thus increases the cost of heat dissipation and ventilation. In view of the shortcomings of the existing technology, we propose a greenhouse ventilation device based on solar photovoltaic power generation to solve the above problems. Utility Model Content

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The utility model embodiment discloses a greenhouse ventilation device based on solar photovoltaic power generation.

[0031] According to the attached Figure 1-6As shown, it includes a ventilation device body 1, and the ventilation device body 1 includes a mounting frame 101 fixedly mounted at the bottom end of the photovoltaic power generation greenhouse, and the mounting frame 101 has the function of mounting the ventilation device body 1;

[0032] Multiple groups of first sealing plates 2 and second sealing plates 3 are arranged on both sides of the installation frame 101. The first sealing plates 2 and the second sealing plates 3 are arranged alternately, and the first sealing plates 2 and the second sealing plates 3 seal the greenhouse; when in use, the side walls of the multiple groups of first sealing plates 2 and the second sealing plates 3 fit together, which can seal the photovoltaic power generation greenhouse. When ventilation is needed, by starting the driving motor 405, the driving rod 401 drives the two groups of sealing plates away from each other, so that a ventilation gap 23 is formed between the two groups of sealing plates, and then the heat inside the greenhouse can be ventilated and dissipated through the ventilation gap 23, thereby reducing the heat inside the greenhouse.

[0033] A driving unit 4 is provided inside the bottom end of the mounting frame 101, and the driving unit 4 drives the first sealing plate 2 and the second sealing plate 3 to slide away from each other, so that a ventilation gap 23 is formed between the first sealing plate 2 and the second sealing plate 3. When ventilation is required, the driving rod 401 rotates to make the first driving member 402 and the second driving member 403 move away from each other along the direction of the positive thread 4011 and the negative thread 4012, thereby being able to simultaneously drive multiple groups of first sealing plates 2 and second sealing plates 3 to slide away from each other, so that ventilation gaps 23 are formed between the multiple groups of sealing plates.

[0034] The second sealing plate 3 is slidably connected to the inside of the first sealing plate 2. The first sealing plate 2 and the second sealing plate 3 are both slidably connected to the inside of the installation frame 101. The driving unit 4 includes:

[0036] The first driving member 402 and the second driving member 403 are slidably connected to the outer wall of the driving rod 401; in the process of driving the two groups of sealing plates away from each other, the first sealing plates 2 located at both ends of the installation frame 101 can slide into the interior of the storage frame 406 for storage, and at the same time, the second sealing plate 3 can slide inside the adjacent group of first sealing plates 2.

[0037] The bottom ends of the first sealing plate 2 and the second sealing plate 3 are connected to the top ends of the two groups of driving members respectively.

[0038] The outer wall of the driving rod 401 is provided with positive threads 4011 and negative threads 4012 at intervals, and the positive threads 4011 and the negative threads 4012 are arranged alternately. The positive threads 4011 and the negative threads 4012 correspond to the positions of the first sealing plate 2 and the second sealing plate 3 respectively.

The connecting piece 4021 is slidably connected to the inside of the driving groove 4022. It should be noted that the connecting pieces 4021 on both sides are fixedly connected to the first driving piece 402, so that the connecting pieces 4021 on both sides are respectively fixedly connected to the bottom ends of both sides of the first sealing plate 2, so that the second sealing plate 3 can slide inside the first sealing plate 2, so that the two groups of sealing plates can completely seal the greenhouse.

[0040] The connecting member 4021 and the bottom end surface of the second sealing plate 3 are fixedly connected to the first driving member 402 and the second driving member 403 respectively, and can control the driving motor 405 according to the opening and closing size of the ventilation gap 23 to meet the ventilation needs. At the same time, ventilation can be carried out at any place inside the greenhouse to improve the ventilation effect. The driving motor 405 is installed on one side of the installation frame 101, and the output end of the driving motor 405 is fixedly connected to one end of the driving rod 401.

The protective frame 404 protects the driving motor 405 and can remotely control the opening and closing of the driving motor 405. The outer walls of both sides of the installation frame 101 are fixedly connected with storage frames 406.

[0041] In summary, compared with the prior art, the present invention has the following beneficial effects: by installing multiple groups of first sealing plates 2 and second sealing plates 3 on both sides of the installation frame 101, the photovoltaic power generation greenhouse can be completely sealed, and only one group of driving motors 405 is required. Through the cooperation of the driving rod 401 and the two groups of driving parts, ventilation gaps 23 can be formed between the multiple groups of first sealing plates 2 and the second sealing plates 3, so that the heat of the photovoltaic power generation greenhouse can be dissipated through the multiple groups of ventilation gaps 23, thereby improving the ventilation quality of the photovoltaic power generation greenhouse.
