Description

Technical Field

[0001] This utility model relates to the field of heat dissipation window technology, specifically to a ventilation and heat dissipation window for use in underground coal mines. Background Technology

[0002] In coal mining, underground mining is the most important method. However, since most coal mines are buried underground, underground mining must be used. Underground mining is a mining method that corresponds to open-pit mining. Underground mining technology is much more difficult. To prevent excessively high temperatures, underground coal mines are usually equipped with ventilation windows.

[0003] Current ventilation windows use multiple blades to change the size of the air vents, typically employing chain or meshing drives to rotate them. This results in a complex transmission structure, difficult maintenance, and the filters inside the ventilation windows require disassembly for cleaning, lacking an automatic cleaning function. There is an urgent need to design a ventilation window for underground coal mines to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a ventilation and heat dissipation window for underground coal mines to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A ventilation and heat dissipation window for underground coal mines includes a mounting frame, a filter screen slidably fitted within the mounting frame, and multiple fan blades rotatably fitted within the mounting frame. A connecting plate is located at the end of each fan blade furthest from the mounting frame, and one side of the connecting plate engages with and rotatably with one end of each fan blade. A driving mechanism that cooperates with the connecting plate is provided within the mounting frame. Brushes are rotatably fitted at one end of the mounting frame for each fan blade, and these brushes cooperate with the filter screen. A water pipe is located at the top of the mounting frame for connecting to an external water supply device. Multiple water outlets are located at the top of the inner wall of the mounting frame. A water storage box is installed on one side of the bottom of the filter screen, corresponding to the multiple water outlets. A drain outlet is located at the bottom of the water storage box.

[0007] Furthermore, mounting blocks are provided at the top and bottom of the mounting frame, and mounting bolts are provided inside the mounting blocks.

[0008] Furthermore, the driving mechanism includes a rotating rod rotatably fitted within the mounting frame, a connecting rod mounted at one end of the rotating rod, and a motor mounted on one side of the mounting frame. The output end of the motor is fixedly connected to one end of the rotating rod, and one end of the connecting rod is rotatably connected to one end of the connecting plate.

[0009] Furthermore, the mounting frame is provided with multiple fixing pins corresponding to the multiple fan blades, and one end of each fan blade has a pin hole. The fixing pins and the pin holes are slidably engaged and rotatably engaged.

[0010] Furthermore, one side of the connecting plate is provided with multiple buckles corresponding to the multiple fan blades, and one end of each of the multiple fan blades is provided with a locking rod. The buckles and the locking rods engage and rotate with each other. Both sides of the fan blades are provided with grooves corresponding to the connecting plate.

[0011] Furthermore, both sides of the mounting frame are threaded with fixing bolts, and the two fixing bolts abut against the two sides of the water storage box respectively. A handle is provided at the bottom of the water storage box.

[0012] In the above technical solution, the ventilation and heat dissipation window for underground coal mines provided by this utility model has the following beneficial effects:

[0013] The connecting plate allows the drive mechanism to pull the plate, causing multiple fan blades to rotate, opening or closing them. The overall transmission structure is simple, and damaged blades can be easily replaced for convenient maintenance. This makes it suitable for ventilation and heat dissipation in underground coal mines. The included brushes, driven by the connecting plate, clean the filter screen as the fan blades rotate. This automatic cleaning of the filter screen during the opening and closing of the fan blades ensures long-term filter life. The water outlet allows water to be sprayed from the pipe, further cleaning the filter screen and brushes, improving self-cleaning efficiency. The water storage box stores water, making ventilation and heat dissipation even cooler. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown in the figure, this utility model provides a ventilation and heat dissipation window for use in underground coal mines.

[0022] The system includes a mounting frame 1, a filter screen 2 that slides within the mounting frame 1, and multiple blades 3 that rotate within the mounting frame 1. A connecting plate 4 is located at one end of each blade 3 away from the mounting frame 1, with one side of the connecting plate 4 engaging and rotating with one end of each blade 3. A drive mechanism 5 that engages with the connecting plate 4 is located within the mounting frame 1. Brushes 6 are located at one end of each blade 3 that rotate within the mounting frame 1, engaging with the filter screen 2. A water pipe 7 is located at the top of the mounting frame 1 for connecting to an external water supply device. Multiple water outlets 8 are located at the top of the inner wall of the mounting frame 1. A water storage box 9 is installed on one side of the bottom of the filter screen 2, corresponding to the multiple water outlets 8. A drain outlet is located at the bottom of the water storage box 9.

[0023] Reference Figure 1 In this embodiment, mounting blocks 10 are provided at both the top and bottom of the mounting frame 1, and mounting bolts 11 are provided inside the mounting blocks 10. The mounting bolts 11 can pass through the mounting blocks 10 to connect to the outside and install and fix the mounting frame 1.

[0024] Reference Figure 2 The drive mechanism 5 in this embodiment includes a rotating rod 12 rotatably fitted within the mounting frame 1, a connecting rod 13 mounted at one end of the rotating rod 12, and a motor 14 mounted on one side of the mounting frame 1. The output end of the motor 14 is fixedly connected to one end of the rotating rod 12, and one end of the connecting rod 13 is rotatably connected to one end of the connecting plate 4. Through the connecting rod 13, the motor 14 drives the rotating rod 12 to rotate, causing the rotating rod 12 to drive the connecting rod 13. The connecting rod 13 then pulls the connecting plate 4, causing the connecting plate 4 to drive multiple fan blades 3 to rotate.

[0025] Reference Figure 3 In this embodiment, the mounting frame 1 is provided with multiple fixing pins 15 corresponding to multiple fan blades 3. One end of the fan blade 3 has a pin hole 16, and the fixing pin 15 slides and rotates with the pin hole 16. The fixing pin 15 passes through the mounting frame 1 and the pin hole 16 to fix the fan blade 3, allowing one end of the fan blade 3 to rotate on the fixing pin 15. When disassembling the fan blade 3, the corresponding fixing pin 15 can be pulled out.

[0026] Reference Figure 3 In this embodiment, the connecting plate 4 has multiple latches 17 on one side corresponding to multiple fan blades 3. Each fan blade 3 has a locking rod 18 at one end. The latches 17 and locking rods 18 engage and rotate with each other. Both sides of the fan blades 3 have grooves 19 corresponding to the connecting plate 4. Through the latches 17, multiple latches 17 can engage with multiple locking rods 18, allowing the connecting plate 4 to drive multiple fan blades 3 via the latches 17. After separating the latches 17 from the locking rods 18, individual fan blades 3 can be disassembled.

[0027] Reference Figure 4 In this embodiment, both sides of the mounting frame 1 are threaded with fixing bolts 20, which abut against the two sides of the water storage box 9. A handle 21 is provided at the bottom of the water storage box 9. By rotating the fixing bolts 20, the water storage box 9 can be released from its fixation. Pulling the handle 21 moves the water storage box 9, causing the water storage box 9 to move the filter screen 2, thus removing the filter screen 2 and the water storage box 9 from the bottom of the mounting frame 1.

[0028] Working principle: In use, first install the mounting frame 1 at the ventilation opening in the coal mine, then insert the filter screen 2 into the mounting frame 1 and fix it. The water storage box 9 will also be fixed in the mounting frame 1 along with the filter screen 2. When ventilation and heat dissipation are needed, the drive mechanism 5 will pull the connecting plate 4, causing the connecting plate 4 to drive multiple fan blades 3 to rotate and open. The multiple fan blades 3 can adjust the size and direction of the ventilation opening according to the rotation angle, allowing the ventilation opening to provide corresponding ventilation and heat dissipation. During the ventilation and heat dissipation process, the filter screen 2 will filter dust in the air. When multiple blades 3 rotate, they also drive brushes 6, which clean the filter screen 2. When overheating occurs or there is a lot of dirt on the filter screen 2 and brushes 6, the external water supply equipment can supply water to the water pipe 7, and the water will spray out through the water pipe 7 to the outlet 8. While cleaning the filter screen 2 and brushes 6, the ventilation air will be cooler. The falling water will be collected in the water storage box 9, where the water will absorb dust. When parts are damaged after long-term use, the filter screen 2 and blades 3 can be disassembled and replaced, making it suitable for use in harsh environments such as underground coal mines.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
