Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-7 , the present utility model provides a technical solution: a green building ventilation and energy-saving device, including a ventilation pipe 1, fixed heads 101 are fixedly connected to both ends of the ventilation pipe 1, limit grooves 3 are symmetrically opened on the separation surfaces of the two fixed heads 101, limit pins 302 are slidably installed in the limit grooves 3, an insertion slot 102 is opened on the upper surface of the fixed head 101, a filter plate 4 is slidably installed in the insertion slot 102, limit holes 402 are opened on both sides of the filter plate 4, and the limit holes 402 cooperate with the limit pins 302. A waterproof cover 2 is fixedly connected to the rear of the rear fixed head 101, a waterproof flange 104 is fixedly connected to the inner bottom of the ventilation pipe 1, a support plate 5 is provided in the ventilation pipe 1, a power motor 502 is fixedly connected to the rear of the support plate 5, and a ventilation blade 503 is fixedly connected to the output end of the power motor 502.

[0024] In this implementation scheme, starting the power motor 502 can drive the ventilation blades 503 to rotate. The rotation of the ventilation blades 503 will suck the outside air from the rear end of the ventilation pipe 1 and discharge it into the room, ventilating and exhausting the room. At the same time, the rear end of the ventilation pipe 1 is located outdoors, and the waterproof cover 2 is fixed at the position of the rear end of the ventilation pipe 1 with the opening facing downwards, which can prevent rainwater from slanting into the interior of the ventilation pipe 1. At the same time, a waterproof convex edge 104 is provided at the inner bottom of the ventilation pipe 1 to form a step inside the ventilation pipe 1. When a small amount of rainwater enters the interior of the ventilation pipe 1, the waterproof convex edge 104 will block the rainwater from entering the front end of the ventilation pipe 1 and entering the room. The filter plate 4 is inserted into the insertion slot 102, and the limit pin 302 and the limit hole 402 cooperate with each other to fix the filter plate 4 inside the insertion slot 102. When routine maintenance and repair of the equipment inside the ventilation pipe 1 are required, only the limit pin 302 needs to be moved so that the limit pin 302 moves out of the limit hole 402, and the restriction on the filter plate 4 can be released. At this time, the filter plate 4 can be easily pulled out of the insertion slot 102, facilitating the maintenance personnel to maintain and repair the equipment inside the ventilation pipe 1.

[0025] Among them, in order to achieve the purpose of facilitating maintenance, the present device is implemented by the following technical solutions: sliding card slots 103 are provided on the inner walls of both sides of the ventilation pipe 1, limit sliding plates 501 are fixedly connected to both sides of the support plate 5, and the limit sliding plates 501 are slidably matched with the sliding card slots 103. A solar panel 201 is fixedly connected to the waterproof cover 2.

[0026] Through the sliding cooperation of the sliding card slot 103 and the limit sliding plate 501, after the limit sliding plate 501 is slidably installed in the sliding card slot 103, the filter plate 4 is inserted into the insertion slot 102. At this time, both ends of the ventilation pipe 1 will be blocked by the filter plate 4, and at the same time, the limit sliding plate 501 is fixed inside the sliding card slot 103, and then the support plate 5 is fixed inside the ventilation pipe 1. After the filter plate 4 is removed, the limit sliding plate 501 can be slid out of the sliding card slot 103 horizontally, facilitating the removal of the power motor 502 for maintenance. The solar panel 201 is fixed on the waterproof cover 2, which can convert sunlight into electricity and store it in the storage battery through the power supply module, and then use the storage battery to provide power for the power motor 502.

[0027] Among them, in order to achieve the purpose of fixing the filter plate 4, the present device is implemented by the following technical solutions: a return spring 301 is fixedly connected inside the limit groove 3, the other end of the return spring 301 is fixedly connected to the limit pin 302, a displacement handle 303 is fixedly connected to the limit pin 302, and a number of filter holes 401 are provided in the filter plate 4.

[0028] The return spring 301 can provide a certain thrust to the limit pin 302. The limit pin 302 will be inserted into the interior of the limit hole 402 under the thrust, thereby fixing the filter plate 4 in the insertion slot 102. The displacement handle 303 can drive the limit pin 302 to move. The filter holes 401 can filter foreign matters in the air, such as floating plastic bags and the like.

[0029] The working principle and usage process of the present utility model: When in use, the device needs to be installed in a preset hole in the building, with the rear end of the ventilation pipe 1 facing the sunny side outside. The sunlight can directly irradiate the solar panel 201 to be converted into electricity. Starting the power motor 502 can drive the ventilation blades 503 to rotate. The rotation of the ventilation blades 503 will suck the outside air from the rear end of the ventilation pipe 1 and discharge it into the room for ventilation and exhaust in the room. When daily maintenance and repair of the equipment inside the ventilation pipe 1 are required, move the displacement handle 303 to drive the limit pin 302 out of the interior of the limit hole 402, and the restriction on the filter plate 4 can be released. At this time, the filter plate 4 can be easily pulled out of the interior of the insertion slot 102. Without the restriction of the filter plate 4, the limit sliding plate 501 can be moved out of the interior of the sliding slot 103, thereby moving the support plate 5 and the power motor 502 out of the interior of the ventilation pipe 1, facilitating subsequent maintenance and repair.

[0030] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
