Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model provides a ventilation regulating device for coal mine roadways, including a ventilation duct 101, with an air inlet 102 and an air outlet 103 at both ends, which are respectively connected to a ventilation system. A baffle plate 104 is installed inside the ventilation duct 101, and multiple sets of first air inlets 105 for roadway ventilation are provided on the baffle plate 104; it also includes:

[0028] A connecting component, located inside the ventilation duct 101, is used for telescopic connection of the wind deflector 104;

[0029] An adjustment component is located on one side of the baffle plate 104 and is used to adjust the ventilation area within the ventilation duct 101.

[0030] A guide component is disposed between the wind deflector 104 and the adjustment component for guiding the adjustment component during the adjustment process.

[0031] A push component, located inside the ventilation duct 101, is used to push the adjustment component in adjustment.

[0032] It should be noted that during the process of adjusting the ventilation in the coal mine roadway, the ventilation area in the ventilation duct 101 is adjusted by adjusting the size of the area connecting the first intake air duct 105 and the second intake air duct 302 through the cooperation of the adjustment components, guide components, connecting components and pushing components. This allows for quick and effective adjustment of the ventilation volume according to the actual situation in the coal mine roadway, meeting the needs of coal mines for flexible ventilation adjustment.

[0033] It is worth noting here that a ventilation system refers to a combination of equipment and pipes that systematically transports and exhausts air through mechanical or natural means to achieve indoor and outdoor air exchange, improve air quality, regulate temperature and humidity, or control pollutant concentrations. As this is existing technology, it will not be elaborated on further.

[0034] Multiple sets of connecting components are provided, and the multiple sets of connecting components are evenly distributed at the four corners of the wind deflector 104; the connecting components include a connecting block 201 fixedly connected to the inner wall of the ventilation duct 101, a sleeve 202 fixedly connected to the connecting block 201, a sliding rod 203 slidably connected to the sleeve 202, the sliding rod 203 being fixedly connected to the wind deflector 104, and a spring 204 sleeved on the outer side of the sleeve 202;

[0035] It should be noted that the wind deflector 104 is slidably guided by the sleeve 202 and the slide rod 203, and the wind deflector 104 is reset by the elastic force of the spring 204.

[0036] The adjustment assembly includes an adjustment plate 301 disposed on one side of the wind deflector 104, and the adjustment plate 301 abuts against the wind deflector 104. A second air inlet 302 is provided on the adjustment plate 301, and the second air inlet 302 is matched with the first air inlet 105.

[0037] It should be noted here that the ventilation area in the ventilation duct 101 is adjusted by adjusting the plate 301 and the second air inlet 302.

[0038] Two sets of guide components are symmetrically arranged on the wind deflector 104. The guide components include a circular hole 403 opened on the adjustment plate 301, a connecting rod 401 slidably connected to the circular hole 403, and a fixing block 402 fixedly connected to both ends of the connecting rod 401. The fixing block 402 is fixedly connected to the wind deflector 104.

[0039] It should be noted here that the sliding of the adjusting plate 301 is guided by the circular hole 403, the connecting rod 401, and the fixing block 402.

[0040] The connecting rod 401 is provided with a limiting component for limiting the downward position of the adjusting plate 301. The limiting component is a limiting ring 5, which is fixedly sleeved on the connecting rod 401.

[0041] It should be noted here that the lowering position of the adjusting plate 301 is limited by the limiting ring 5.

[0042] The pushing component includes two sets of pins 601 symmetrically fixed on the adjusting plate 301. Two sets of pushing blocks 602 are fixedly connected to the bottom inner side of the ventilation duct 101. The two sets of pushing blocks 602 are respectively arranged in correspondence with the two sets of pins 601. An inclined surface 603 is provided on the pushing block 602. One end of the pin 601 is abutted against the inclined surface 603.

[0043] It should be noted that during the sliding of the baffle plate 104, the movement of the baffle plate 104 drives the adjustment plate 301 to move. The movement of the adjustment plate 301 drives the pin 601 fixed on the adjustment plate 301 to move. During the movement of the pin 601, one end of the pin 601 abuts against the inclined surface 603 on the push block 602. Through the abutting action between the pin 601 and the push block 602, the adjustment plate 301 slides upward on the connecting rod 401, causing a greater parallel misalignment between the first air inlet 105 and the second air inlet 302, creating a larger interconnected area, and adjusting the ventilation area in the ventilation duct 101.

[0044] Working principle: When using the ventilation regulating device for coal mine roadways to ventilate the roadways, first connect the air inlets 102 and air outlets 103 at both ends of the ventilation duct 101 to the ventilation system. Then start the ventilation system. Through the wind force in the ventilation system blowing the wind baffle 104 and the pushing component pushing the regulating plate 301, the first air inlet 105 and the second air inlet 302 are parallel and misaligned and connected, thus completing the ventilation treatment of the coal mine roadway.

[0045] As the airflow inside the ventilation system increases, during the adjustment of ventilation volume in the coal mine roadway, the continuously increasing airflow causes the baffle plate 104 to continue sliding inside the ventilation duct 101 via the connecting components. During the sliding of the baffle plate 104, the movement of the baffle plate 104 drives the adjusting plate 301 to move. This movement of the adjusting plate 301, in turn, drives the pin 601 fixed to it to move. During the movement of the pin 601, one end of the pin 601 abuts against the inclined surface 603 on the pushing block 602, thus... The interaction between shaft 601 and push block 602 causes adjusting plate 301 to slide upward on connecting rod 401, resulting in a greater parallel misalignment between first inlet air 105 and second inlet air 302, creating a larger interconnected area. The greater the wind force in the ventilation system, the larger the interconnected area between first inlet air 105 and second inlet air 302, and vice versa. By adjusting the size of the interconnected area, the ventilation area within ventilation duct 101 can be adjusted, enabling rapid and effective adjustment of ventilation volume based on actual conditions in the roadway, thus meeting the demand for flexible ventilation adjustment in coal mining.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
