[0002] Ventilation in basement equipment rooms serves to eliminate residual heat, moisture, and harmful substances, effectively ensuring the normal operation of equipment. By installing a mechanical exhaust system, the number of air changes per hour should meet the required standards. At the same time, good airflow organization should be maintained in the equipment room to avoid dead zones. During ventilation, airflow can carry dust into the equipment room. To prevent damage to equipment, filters are often installed in the ventilation ducts. Traditional filters are fixed with bolts, making replacement cumbersome and inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a ventilation system for basement equipment rooms to solve the problem of inconvenient replacement of filters in existing ventilation ducts.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A ventilation system for a basement equipment room includes a ventilation duct, a waterproof cover at the ventilation end of the ventilation duct, a fan at the ventilation exchange end of the ventilation duct, a groove on the lower surface of the ventilation duct, a filter screen slidably connected to the ventilation duct through the groove, and a quick-release device for quickly removing and installing the filter screen at the lower end of the filter screen. The quick-release device includes a housing, two housing pieces are fixedly connected to the surface of the filter screen, and a limiting mechanism that provides a limit for the filter screen is slidably connected to the housing.

[0006] Furthermore, the aforementioned limiting mechanism includes a sliding block, which is slidably connected to the inside of the housing. A rotating seat is fixedly connected to each side of the sliding block, and the rotating seat is rotatably connected to a rotating shaft. A slide rail is provided inside the housing, which is slidably connected to the rotating shaft. A limiting block is fixedly connected to the surface of the rotating shaft. A spring component that drives the limiting block to move is fixedly connected to the limiting block. A power component that drives the sliding block to move is fixedly connected to the lower end of the sliding block.

[0007] Furthermore, the aforementioned spring component includes a first spring, one end of which is fixedly connected to a limiting block, and the other end of which is fixedly connected to a sliding block.

[0008] Furthermore, the aforementioned power assembly includes a transmission block, which is fixedly connected to the lower end of the sliding block, slidably connected to the housing, and a reset element is fixedly connected to the upper end of the sliding block.

[0009] Furthermore, the aforementioned reset element includes a second spring, with the upper end of the sliding block fixedly connected to the second spring, and the upper end of the second spring fixedly connected to the inner wall of the housing.

[0010] Furthermore, the housing is provided with a lubricating oil groove.

[0011] Furthermore, the surface of the aforementioned transmission block is provided with anti-slip texture.

[0012] Furthermore, the ventilation duct is equipped with a limiting strip inside.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model uses an upward-pushing transmission block to drive a sliding block to move upward, which in turn drives a rotating seat to move upward, allowing the limiting block to enter the slide rail. This does not interfere with the movement of the filter screen and facilitates quick and easy assembly and disassembly of the filter screen.

[0015] 2. This utility model allows the transmission block to be released, and the second spring pushes the transmission block to reset, causing the limiting block to unfold automatically. This provides a limit for the filter screen inside the ventilation pipe, completing the installation work. Compared with traditional bolt fixing, this reduces the number of operation steps and speeds up the work. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-3As shown, a ventilation system for a basement equipment room includes a ventilation duct 101. A waterproof cover 102 is provided at the ventilation end of the ventilation duct 101, and a fan 103 is provided at the air exchange end of the ventilation duct 101. A groove 201 is formed on the lower surface of the ventilation duct 101. A filter screen 202 is inserted laterally into the ventilation duct 101 through the groove 201. The two sides of the filter screen 202 are respectively limited by the groove walls of the groove 201. A quick-release device for quickly assembling and disassembling the filter screen 202 is provided at the lower end of the filter screen 202. The quick-release device includes a housing 301. Two housings 301 are fixedly connected to the surface of the filter screen 202. The housings 301 are slidably connected to a limiting mechanism that provides a limit for the filter screen 202. By connecting the ventilation end of the ventilation duct 101 to the basement machine room and the ventilation outlet of the ventilation duct 101 to the outside, ventilation conditions are provided for the basement machine room. The fan 103 drives the airflow to exchange gases between the basement machine room and the outside to complete the ventilation work. At the same time, the filter screen 202 filters the dust particles contained in the airflow to keep the basement machine room clean.

[0024] like Figure 3 and Figure 4 As shown, the limiting mechanism includes a sliding block 302, which is slidably connected to the inside of the housing 301. A rotating seat 303 is fixedly connected to each side of the sliding block 302, and the rotating seat 303 is rotatably connected to the rotating shaft 305. A slide rail 304 is provided inside the housing 301, which is slidably connected to the rotating shaft 305. A limiting block 306 is fixedly connected to the surface of the rotating shaft 305, and a spring component that drives the limiting block 306 to move is fixedly connected to the limiting block 306. A power component that drives the sliding block 302 to move is fixedly connected to the lower end of the sliding block 302. When the rotating shaft 305 moves upward, the rotating shaft 305 drives the limiting block 306 into the slide rail 304, without interfering with the installation of the filter screen 202. When the rotating shaft 305 moves downward, the limiting block 306 unfolds, and the limiting block 306 provides a limit for the second spring 401 inside the ventilation pipe 101. By fixing the two second springs 401, the filter screen 202 is limited, and the filter screen 202 is quickly installed.

[0025] like Figure 3 and Figure 4 As shown, the spring component includes a first spring 307, one end of which is fixedly connected to a limiting block 306, and the other end of which is fixedly connected to a sliding block 302. The first spring 307 provides power to the limiting block 306. When the limiting block 306 slides out of the slide rail 304, it drives the limiting block 306 to unfold, automatically providing a limit for the filter screen 202.

[0026] like Figure 3 and Figure 4As shown, the power assembly includes a transmission block 402, which is fixedly connected to the lower end of the sliding block 302 and slidably connected to the housing 301. A reset element is fixedly connected to the upper end of the sliding block 302. When the transmission block 402 is pushed upward, the sliding block 302 moves upward, which drives the rotating seat 303 to move upward, providing conditions for inserting the filter screen 202. When the transmission block 402 moves downward, it drives the sliding block 302 to move. The downward movement of the sliding block 302 drives the limiting block 306 to pull out the slide rail 304, providing conditions for limiting the slide rail 304.

[0027] like Figure 4 and Figure 5 As shown, the reset element includes a second spring 401. The upper end of the sliding block 302 is fixedly connected to the second spring 401. The upper end of the second spring 401 is fixedly connected to the inner wall of the housing 301. When the transmission block 402 is released, the second spring 401 pushes the transmission block 402 downward, causing the limit block 306 to automatically unfold, providing a limit for the filter screen 202 and completing the installation work.

[0028] The above embodiment provides a ventilation system for a basement equipment room. By connecting the ventilation duct 101 (ventilation end) to the basement equipment room and the ventilation outlet end to the outside, ventilation conditions are provided for the basement equipment room. A fan 103 drives airflow, enabling gas exchange between the basement equipment room and the outside to complete the ventilation work. A filter 202 filters dust particles in the airflow, keeping the basement equipment room clean. When the filter 202 needs to be replaced, the sliding block 302 is moved upward by pushing the transmission block 402 upward. When the filter screen 202 is moved, the sliding block 302 drives the rotating seat 303 to move upward, and the limiting block 306 enters the slide rail 304 without interfering with the disassembly of the filter screen 202. The filter screen 202 is then pulled out from the ventilation pipe 101 and cleaned. When the filter screen 202 is installed, the transmission block 402 is pushed upward to insert the filter screen 202 into the ventilation pipe 101. When the transmission block 402 is released, the second spring 401 pushes the transmission block 402 downward, causing the rotating shaft 305 to automatically unfold and provide a limit for the filter screen 202, thus completing the installation.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
