[0002] In coal mining operations, electrical equipment is constantly exposed to harsh environments with high dust concentrations and high humidity. Aluminum radiators, as key heat dissipation components in coal mine electrical equipment, directly impact the operational stability and lifespan of the equipment. However, dust easily accumulates between the aluminum fins of the radiator. This dust buildup severely hinders heat dissipation, causing the electrical equipment to overheat, potentially leading to equipment malfunctions or even safety accidents.

[0003] A search revealed that Chinese Patent Publication No. CN119009899B discloses a motor temperature protection device for a coal mine air compressor, which includes a motor body and an electrical box installed on the motor body. It also includes a conversion mechanism, a first cleaning component, and a second cleaning component installed in the electrical box. The second cleaning component works synchronously with the first cleaning component and cleans the fan cover of the motor body.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects: In the prior art, electrical equipment is cleaned using a cleaning component. However, the cleaning component is not cleaned promptly after use, resulting in secondary pollution of the electrical equipment. In order to solve the problem of secondary pollution of electrical equipment by the cleaning component in the prior art, this application integrates mechanical cleaning with negative pressure adsorption and positive pressure back-blowing self-cleaning by integrating the cleaning roller, thereby solving the problems of poor heat dissipation due to ash accumulation on the aluminum drain and secondary pollution of the cleaning component. Utility Model Content

[0006] This application provides an intelligent heat dissipation control device for coal mine electrical equipment, employing the following technical solution: It includes an aluminum busbar and slide rails disposed on both sides of the aluminum busbar. Each slide rail is slidably connected to a sliding frame. A linear actuator is mounted on each sliding frame, driving the sliding frame to reciprocate along the slide rails. A hollow rotating rod is rotatably connected to the two sliding frames. Multiple hollow cleaning rollers are mounted on the rotating rod, with through holes on their inner walls. The inner cavity of each cleaning roller communicates with the inner cavity of the rotating rod through a corresponding through hole. A motor is fixedly mounted on one of the sliding frames, with the motor's output shaft coaxially and fixedly connected to the rotating rod. The linear actuator drives the sliding frames and cleaning rollers to reciprocate, thereby removing dust from the sidewalls of the aluminum busbar.

[0007] Optionally, the rotating rod is provided with an inner tube, the outer wall of which is in contact with the inner wall of the rotating rod.

[0008] Optionally, the inner tube is a hollow structure, and the inner tube is fixedly connected to the sliding frame. An axial partition is provided in the inner cavity of the inner tube, which divides the inner cavity of the inner tube into a first chamber and a second chamber.

[0009] Optionally, each of the axial partition plates has a through groove on the outer wall of the inner tube opposite to each other.

[0010] Optionally, both ends of the inner tube are provided with blind plates, and the blind plates are provided with a first hole that can communicate with the first chamber and a second hole that can communicate with the second chamber.

[0011] Optionally, a first pipe is provided on the first hole, and the first pipe can be connected to an air blowing device.

[0012] Optionally, a second pipe is provided on the second hole, and the second pipe can be connected to a negative pressure suction device.

[0013] Optionally, each cleaning roller has an adsorption hole on its side wall, the adsorption hole is connected to the inner cavity of the corresponding cleaning roller, and a filter screen is provided on the adsorption hole.

[0014] Optionally, each cleaning roller is provided with a brush on its sidewall.

[0015] Optionally, the sliding frame is equipped with a negative pressure suction hood, which is connected to a negative pressure suction device; the negative pressure suction device collects the dust blown out through the negative pressure suction hood to avoid pollution.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] 1. The brush on the side wall of the cleaning roller of this utility model can effectively sweep away the dust hidden in the grooves of the aluminum strip side wall through mechanical friction; at the same time, when the inner cavity of the cleaning roller is connected with the second chamber to form a negative pressure, the adsorption holes can suck in the dust and temporarily store it on the surface of the filter screen, so as to prevent the dust from flying and improve the cleaning effect.

[0018] 2. In this invention, when the cleaning roller rotates into the negative pressure suction hood, its inner cavity is connected to the blowing device through the first chamber to form a positive pressure. The airflow enters the inner cavity of the cleaning roller through the through groove and is ejected from the adsorption hole, which can blow off the dust adhering to the filter screen surface and simultaneously wash away the residual dirt on the brush, restoring the cleaning roller to a clean state and avoiding secondary pollution of the aluminum busbar due to dust adhering to the brush. During the positive pressure back-blowing self-cleaning process of the cleaning roller, the negative pressure suction hood is activated simultaneously, sucking the blown-off dust into the external collection device, further preventing dust pollution of the environment and ensuring the cleanliness of the entire cleaning process.

[0026] The following is in conjunction with the appendix Figures 1-6 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] This application discloses an intelligent heat dissipation control device for electrical equipment in coal mines. For example... Figure 1 As shown, it includes an aluminum busbar 1 and slide rails 2 arranged on both sides of the aluminum busbar 1. The feature is that: each slide rail 2 is slidably connected to a sliding frame 3; the sliding frame 3 is provided with a linear actuator 4, which can drive the sliding frame 3 to reciprocate along the slide rail 2; the two sliding frames 3 are rotatably connected to a hollow rotating rod 5, and the rotating rod 5 is provided with a plurality of hollow cleaning rollers 6. Each cleaning roller 6 has a through hole 7 on its inner peripheral wall, and the inner cavity of each cleaning roller 6 communicates with the inner cavity of the rotating rod 5 through the corresponding through hole 7.

[0028] In this embodiment, in order to increase the heat dissipation area, the common aluminum busbar 1 has grooves on its side wall. When dust is hidden in the grooves, it cannot be directly sucked out of the grooves of the aluminum busbar 1 by the dust collection equipment.

[0029] In this embodiment, the linear driver 4 drives the sliding frame 3, the rotating rod 5, and the cleaning roller 6 to move back and forth. The rotating rod 5 is driven to rotate by the motor, thereby causing the cleaning roller 6 to rotate, thus completing the cleaning of the side wall of the aluminum strip 1.

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The rotating rod 5 has an inner tube 8, which is fixedly connected to the sliding frame 3. The outer wall of the inner tube 8 is in contact with the inner wall of the rotating rod 5. The inner tube 8 is hollow, and an axial partition 9 is provided in the inner cavity of the inner tube 8, which divides the inner cavity of the inner tube 8 into a first chamber 10 and a second chamber 11. A through groove 12 is opened on the outer wall of the inner tube 8 on each opposite side of the axial partition 9. Blind plates 13 are provided at both ends of the inner tube 8, and the blind plates 13 have openings that can connect with the first chamber 10. The cleaning roller 6 has a first hole and a second hole that communicates with the second chamber 11; a first pipe 14 is provided on the first hole, and the first pipe 14 can be connected to an air blowing device; a second pipe 15 is provided on the second hole, and the second pipe 15 can be connected to a negative pressure suction device; each cleaning roller 6 has an adsorption hole 16 on its side wall, the adsorption hole 16 communicates with the inner cavity of the corresponding cleaning roller 6, and a filter screen is provided on the adsorption hole 16; each cleaning roller 6 has a brush 17 on its side wall.

[0031] In this embodiment, the dust on the side wall of the aluminum busbar 1 is cleaned by the brush 17 on the side wall of the cleaning roller 6. When the inner cavity of the cleaning roller 6 is connected to the second chamber 11, the inner cavity of the cleaning roller 6 is in a negative pressure state, so that the dust on the aluminum busbar 1 can be adsorbed onto the surface of the filter screen.

[0032] When the inner cavity of the cleaning roller 6 is connected to the first chamber 10, the inner cavity of the cleaning roller 6 is under positive pressure. At this time, the dust on the surface of the filter screen can be blown away, and the brush 17 can also be cleaned by the airflow, so as to avoid the dust adhering to the brush 17 and causing secondary pollution to the aluminum busbar 1.

[0033] Please see Figure 1 The sliding frame 3 is equipped with a negative pressure suction hood 18, which is connected to the negative pressure suction device.

[0034] In this embodiment, when the inner cavity of the cleaning roller 6 is under positive pressure, the negative pressure suction hood 18 can suck out the dust cleaned by the filter screen and brush 17, thus avoiding environmental pollution.

[0035] The implementation principle of the intelligent heat dissipation control device for coal mine electrical equipment in this application embodiment is as follows:

[0036] Aluminum busbar 1 is the main heat dissipation unit for electrical equipment in coal mines. The side wall has a groove-like structure to increase the heat dissipation area, but it is prone to dust accumulation.

[0037] Cleaning Mode:

[0038] The linear actuator 4 drives the sliding frame 3 to move along the slide rail 2, aligning the cleaning roller 6 with the area to be cleaned on the aluminum bar 1; the motor drives the rotating rod 5 to rotate, causing the cleaning roller 6 to rotate, and the brush 17 contacts the grooves of the aluminum bar 1, sweeping away dust through mechanical friction; when the cleaning roller 6 rotates to the cleaning area, the corresponding inner cavity of the cleaning roller 6 is connected to the negative pressure suction device through the second chamber 11, forming a negative pressure; the dust on the surface and in the grooves of the aluminum bar 1 is sucked in through the suction holes 16 of the cleaning roller 6 and temporarily stored on the filter screen surface to prevent dust from flying away;

[0039] Backflush mode:

[0040] When the cleaning roller 6 rotates into the negative pressure suction hood 18, the inner cavity of the cleaning roller 6 is connected to the air blowing device through the first chamber 10 and the first pipe 14 to form a positive pressure.

[0041] Airflow enters the inner cavity of the cleaning roller 6 through the channel 12 and is ejected from the adsorption hole 16, blowing off the dust adhering to the filter screen surface and simultaneously washing away residual dirt on the brush 17; the negative pressure suction hood 18 is activated simultaneously to suck the dust blown off during the self-cleaning process into the external collection device to avoid polluting the environment.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
