[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation to the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1 to 5 shown, an embodiment of the present invention provides an air-cooled heat dissipation device, including: a fan assembly 10, a filter screen 20, a carrying frame 30, and a cleaning assembly 40; the fan assembly 10 is used to drive air to flow through the filter screen 20 to the position to be cooled for convective heat transfer; the carrying frame 30 is fixedly arranged and has a sliding groove 31; the cleaning assembly 40 includes a cleaning brush 41 and an elastic member 42; at least a part of the cleaning brush 41 abuts against the filter screen 20; one end of the cleaning brush 41 is slidably arranged in the sliding groove 31 and is in limit cooperation with the inner wall of the sliding groove 31; both ends of the elastic member 42 respectively abut against the cleaning brush 41 and the inner wall of the sliding groove 31, and the extending direction of the elastic member 42 is parallel to the extending direction of the sliding groove 31 to drive the cleaning brush 41 to reset to one end of the sliding groove 31; wherein, the extending direction of the sliding groove 31 is parallel to the extending direction of the filter screen 20 so that the cleaning brush 41 cleans the filter screen 20 along the extending direction of the filter screen 20.

[0032] The utility model makes the efficient cleaning of the filter screen 20 completed by setting the cleaning brush 41 and the elastic member 42 to cooperate. Relying on manual or power equipment to drive the cleaning brush 41 can achieve high-efficiency cleaning of the filter screen 20, and the cleaning brush 41 can be efficiently reset automatically under the elastic force of the elastic member 42, effectively replacing the way of manually holding a brush to clean the filter screen 20, saving manpower, reducing the labor intensity of the staff, and improving the cleaning efficiency of the filter screen 20. By setting the sliding groove 31, it not only ensures the reliable movement of the cleaning brush 41 but also enables the elastic member 42 to be reliably stored, effectively protecting the elastic member 42. In actual use, it is found that in the same manual way, the way of manually pulling the cleaning brush 41 in the utility model to clean the filter screen 20 is significantly better than the existing way of manually holding a brush to clean the filter screen 20. The staff only needs to pull the cleaning brush 41 a few times to complete the cleaning of the filter screen 20, requiring fewer workers, with less labor intensity, saving time and effort and having high work efficiency, which can improve the overall construction efficiency underground in the mine and meet the production needs of rapid excavation. The air-cooled heat dissipation device proposed by the utility model can be flexibly applied to various mining equipment underground in coal mines, with a simple structure, reliable operation, low cost, convenient assembly and subsequent maintenance, suitable for large-scale popularization and use, and can be used in supporting with equipment such as underground mine cars and excavators in the future, having the characteristics of reliable operation and flexible use.

[0033] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the bearing frame 30 further has a through hole communicating with the sliding groove 31, and the extending direction of the through hole is parallel to the extending direction of the sliding groove 31; the cleaning assembly 40 further includes a handle 43 and a pull rod 44. One end of the pull rod 44 is located in the sliding groove 31 and is connected to the cleaning brush 41, and the other end passes through the through hole and extends outside the sliding groove 31 and is connected to the handle 43; the pull rod 44 is in sliding limit fit with the inner wall of the through hole; wherein, pulling the pull rod 44 along the direction away from the through hole by the handle 43 drives the cleaning brush 41 to move to clean the filter screen 20; releasing the handle 43, the elastic member 42 pushes the cleaning brush 41 to reset to the end of the sliding groove 31 away from the through hole.

[0034] By setting the handle 43 and the pull rod 44 to cooperate, the convenience of the staff manually operating the cleaning brush 41 is further ensured.

[0035] As Figure 2 shown, the elastic member 42 is a spring, and the spring is sleeved outside the pull rod 44 and is in limit fit with the pull rod 44.

[0036] By setting the spring to be sleeved outside the pull rod 44 and being in limit fit with the pull rod 44, the reliability of the telescopic movement of the spring is ensured.

[0037] Optionally, the carrier frame 30 further has a through wire hole communicating with the sliding groove 31, and the extending direction of the through wire hole is parallel to the extending direction of the sliding groove 31; the cleaning assembly 40 further includes a handle 43 and a pull rope. One end of the pull rope is located in the sliding groove 31 and is connected to the cleaning brush 41, and the other end passes through the through wire hole and extends out of the sliding groove 31 and is connected to the handle 43; wherein, pulling the pull rope in the direction away from the through wire hole by the handle 43 drives the cleaning brush 41 to move to clean the filter net 20; releasing the handle 43, the elastic member 42 pushes the cleaning brush 41 to reset to the end of the sliding groove 31 away from the through wire hole.

[0038] By setting the cooperation of the handle 43 and the pull rope, it not only further ensures the convenience of the staff to manually operate the cleaning brush 41, but also is lighter than the pull rod 44.

[0039] In a specific embodiment of the present invention, a circular hole convenient for human hand to hold is provided in the middle of the handle 43; when it is necessary to pull the handle 43, directly insert the finger into the circular hole to pull the handle 43, which is more convenient and labor-saving.

[0040] Optionally, the cleaning assembly 40 further includes a guide rod. The two ends of the guide rod are respectively fixedly connected to the inner walls of the sliding groove 31, and the extending direction of the guide rod is parallel to the extending direction of the sliding groove 31; one end of the cleaning brush 41 located in the sliding groove 31 is sleeved outside the guide rod and is in sliding limit fit with the guide rod; the elastic member 42 is a spring, the spring is sleeved outside the guide rod and is in limit fit with the guide rod.

[0041] By setting the guide rod, it not only ensures the reliability of the telescopic movement of the spring, but also ensures the reliability of the reciprocating movement of the cleaning brush 41.

[0042] As Figure 1 、 Figure 3 and Figure 4 shown, the moving range of the cleaning brush 41 covers the filtering surface of the filter net 20; the carrier frame 30 at least covers two opposite sides corresponding to the filter net 20, and the parts of the carrier frame 30 covering two opposite sides corresponding to the filter net 20 respectively have sliding grooves 31; both ends of the cleaning brush 41 are slidably arranged in a sliding groove 31 respectively; there are two elastic members 42, which are respectively located in a sliding groove 31 to jointly drive the cleaning brush 41 to reset to one end of the sliding groove 31.

[0043] By setting that the moving range of the cleaning brush 41 covers the filtering surface of the filter net 20, it ensures the cleaning effect of the filter net 20 when the cleaning brush 41 reciprocates once; by setting two sliding grooves 31, it further ensures the reliability of the reciprocating movement of the cleaning brush 41.

[0044] In a specific embodiment of the present utility model, the horizontal length of the sliding groove 31 is greater than or equal to the horizontal length of the filter net 20, so that the moving stroke of the cleaning brush 41 is greater than the length of the filter net 20, enabling sufficient cleaning of the filter net 20.

[0045] As Figure 1 , Figure 3 and Figure 4 shown, the filter net 20 is vertically arranged; the bearing frame 30 covers the periphery of the filter net 20; the parts of the bearing frame 30 covering the upper and lower sides of the filter net 20 respectively have sliding grooves 31, and the upper and lower ends of the cleaning brush 41 are respectively slidably arranged in a sliding groove 31; the sliding groove 31 extends in the horizontal direction.

[0046] By arranging the bearing frame 30 to cover the periphery of the filter net 20, reliable protection of the filter net 20 is achieved; by arranging the sliding groove 31 to extend in the horizontal direction, the elastic member 42 can be free from the gravity of the cleaning brush 41, further ensuring the reliable reset of the cleaning brush 41.

[0047] Specifically, the air-cooled heat dissipation device further includes a first vibrator, which is connected to the filter net 20 and used to drive the filter net 20 to vibrate for cleaning the filter net 20; and / or, the air-cooled heat dissipation device further includes a second vibrator, which is connected to the cleaning brush 41 and used to drive the cleaning brush 41 to vibrate for cleaning the cleaning brush 41.

[0048] By arranging the first vibrator and the second vibrator, the filter net 20 and the cleaning brush 41 can generate high-frequency oscillations through vibration to loosen and remove the dirt thereon, realizing self-cleaning.

[0049] As Figure 5 shown, the cleaning brush 41 includes a sliding frame 411, a driving motor and a brush head 412. The brush head 412 is rotatably arranged on the sliding frame 411 and is drivingly connected to the driving motor; the driving motor is arranged on the sliding frame 411 to move along with the sliding frame 411, and the driving motor is used to drive the brush head 412 to rotate; one end of the sliding frame 411 is slidably arranged in the sliding groove 31 and is in limit fit with the inner wall of the sliding groove 31; both ends of the elastic member 42 are respectively abutted against the sliding frame 411 and the inner wall of the sliding groove 31; the brush head 412 abuts against the filter net 20 so that the brush head 412 cleans the filter net 20 by rotation.

[0050] With such an arrangement, it not only ensures that the cleaning brush 41 has the function of rotating to clean the filter net 20, but also simplifies the structure of the cleaning brush 41.

[0051] In a specific embodiment of the present utility model, the brush head 412 can be made of nylon brush. The nylon brush is suitable for cleaning the relatively soft filter net 20, and the nylon material will not scratch the filter net 20. The brush head 412 can also be made of stainless steel brush. The stainless steel brush is suitable for cleaning the relatively hard filter net 20, and the stainless steel brush is more durable and can withstand a large frictional force. However, when in use, attention should be paid not to damage the filter net 20.

[0052] The present utility model also provides a mining device, which includes the above-mentioned air-cooled heat dissipation device. The mining device further includes a base 50 and a water tank 60. The water tank 60 is arranged on the base 50 and is used for storing water for heat dissipation circulation. The fan assembly 10, the filter net 20 and the bearing frame 30 are respectively fixedly arranged relative to the base 50. Among them, the fan assembly 10 drives air to blow to the outside of the water tank 60 through the filter net 20 to cool the water tank 60.

[0053] With such a setting, reliable cooling of the water tank 60 is achieved with a simple structure.

[0054] Now, the specific working process and principle of the present utility model are described in detail as follows:

[0055] When it is necessary to clean the filter net 20, the staff stands on the side of the filter net 20 and pulls the handle 43. The handle 43 drives the pull rope, so that the cleaning brush 41 moves to one side. Since the inner side of the cleaning brush 41 is provided with a brush head 412, the movement of the brush head 412 scrapes off the dust attached to the surface of the filter net 20. Through the above setting, it is not necessary for the staff to manually brush the filter net 20 with a brush when cleaning the filter net 20, which improves the cleaning work efficiency.

[0056] In summary, the present utility model provides an air-cooled heat dissipation device and a mining equipment. By setting the cleaning brush 41 and the elastic member 42 to cooperate, the efficient cleaning of the filter net 20 can be completed by driving the cleaning brush 41 manually or by a power device. Moreover, the cleaning brush 41 can be efficiently reset automatically under the elastic force of the elastic member 42, effectively replacing the way of manually holding a brush to clean the filter net 20, saving manpower, reducing the labor intensity of the staff, and improving the cleaning efficiency of the filter net 20. By setting the sliding groove 31, it not only ensures the reliable movement of the cleaning brush 41 but also enables the elastic member 42 to be reliably accommodated, effectively protecting the elastic member 42. In actual use, it is found that, in the same manual way, the way of manually pulling the cleaning brush 41 in the present utility model to clean the filter net 20 is significantly better than the existing way of manually holding a brush to clean the filter net 20. The staff only needs to pull the cleaning brush 41 a few times to complete the cleaning of the filter net 20, requiring fewer workers, with less labor intensity, saving time and effort and having high work efficiency, which can improve the overall construction efficiency underground in the mine and meet the production needs of rapid excavation. The air-cooled heat dissipation device proposed by the present utility model can be flexibly applied to various mining equipment underground in coal mines, with a simple structure and reliable operation, low cost, convenient assembly and subsequent maintenance, suitable for large-scale popularization and use, and can be used in combination with equipment such as underground mine cars and excavators in the future, having the characteristics of reliable operation and flexible use.
