Description

Technical Field

[0001] This utility model relates to the field of underground power technology in coal mines, and in particular to a cable cleaning brush. Background Technology

[0002] Cables are the only conductors for transmitting electricity in underground production. In coal mining operations, the cleaning and maintenance of underground cables is a crucial aspect of ensuring the stable operation of electromechanical systems. The underground coal mine environment is characterized by high humidity, abundant dust, and strong corrosiveness. Coal dust, rock powder, and oil easily adhere to the cable surface, and long-term accumulation can lead to the following problems: decreased cable heat dissipation efficiency (dust buildup forms a heat insulation layer on the cable surface, causing the cable operating temperature to rise, accelerating insulation aging, and increasing the risk of short circuits); increased safety hazards (coal dust accumulation on the cable surface may cause static electricity buildup, posing a fire or explosion risk in flammable and explosive environments); and increased cable maintenance costs (traditional cleaning methods may not be sufficient, requiring cable replacement, consuming significant manpower and resources, and necessitating production shutdowns during cable replacement, reducing work efficiency).

[0003] Currently, the main methods for cleaning transmission cables include: manual wiping, which involves manually cleaning with a brush or cloth, but this method is inefficient, labor-intensive, and poses safety risks associated with working at heights; high-pressure water washing, which can easily lead to water entering the cable joints, causing short circuits, and also results in significant water waste; electric cleaning equipment, which requires an external power source, poses a risk of electric leakage when used underground, and is also bulky and lacks flexibility; and pneumatic cleaning tools, which currently mostly use wind-powered equipment, but there are few specialized tools for cleaning cable surfaces, resulting in poor cleaning effects and potential damage to the cable insulation layer.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] like Figures 1 to 6 As shown, this utility model provides a cable cleaning brush, including a cleaning brush head 1 that abuts against the surface of a cable; a driver 2 whose output shaft is connected to the cleaning brush head 1; a handle 3, with the driver 2 mounted on one end of the handle 3; and a pneumatic assembly 4, including a gas control valve 41, an air inlet pipe 42, a return pipe 43, an air inlet hose 44, and multiple connectors 45. One end of the air inlet pipe 42 is connected to the air inlet of the driver 2 via connectors 45, and the other end of the air inlet pipe 42 is connected to the exhaust port of the gas control valve 41 via connectors 45. One end of the return pipe 43 is connected to the exhaust port of the driver 2 via connectors 45, and the other end of the return pipe 43 extends outward. One end of the air inlet hose 44 is connected to the air inlet of the gas control valve 41 via connectors 45, and the other end of the air inlet hose 44 is connected to an external air compressor. The gas control valve 41 is used to control the flow rate of gas entering the driver 2.

[0020] Specifically, the actuator 2 in this embodiment uses a pneumatic motor. The pneumatic motor can reduce its speed without burning out under overload conditions. Compared to an electric motor, the failure rate of the pneumatic motor is significantly reduced, lowering maintenance costs. The handle 3 in this embodiment is made of industrial-grade PVC material with added UV stabilizers, giving it high toughness and strength. PVC material has a lower density than metal, making it lighter than a metal handle, reducing hand fatigue during prolonged use. The handle 3 is 1.2 meters long, allowing for cleaning cables at different heights within the tunnel. The connector 45 in this embodiment uses a dedicated quick-connect air hose connector. Using the connector 45, the air inlet pipe 42 and air return pipe 43 can be plugged in and used immediately without tools, offering convenience and speed. Compared to traditional threaded connectors 45, the connector 45 in this embodiment significantly improves operational efficiency. In this embodiment, the air inlet pipe 42, the air return pipe 43, and the air inlet hose 44 are all made of transparent plastic hoses. The transparent plastic hoses allow air bubbles to be seen inside the pipes. If bubbles are found, the leak point of the hose can be checked in time.

[0021] In a specific implementation, when cleaning the cable surface, the operator holds the handle 3, and the external air compressor outputs compressed air. The compressed air enters the drive 2 through the gas control valve 41 and the air inlet pipe 42, causing the drive 2 to rotate. As the drive 2 rotates, it drives the cleaning brush head 1 to rotate. The cleaning brush head 1 comes into contact with the cable surface to achieve the cleaning brushing action on the cable surface. The gas control valve 41 can adjust the flow rate of the compressed air, thereby adjusting the speed of the drive 2, so as to achieve different degrees of cleaning effect on the cable surface with different degrees of dirt.

[0022] By setting up a cleaning brush head 1, a driver 2, a handle 3, and a pneumatic component 4, the handle 3 adopts a lightweight design to reduce the operator's workload. Compressed air is used to drive the driver 2 to rotate, which in turn drives the cleaning brush head 1 to rotate, thereby cleaning the cable surface. The entire process does not require electricity, is energy-saving and environmentally friendly, and has a higher safety factor. It is also applicable even in flammable and explosive environments underground.

[0023] Optionally, the cleaning brush head 1 includes a first brush head 11 and a second brush head 12; The first brush head 11 includes a rotating shaft and first bristles. One end of the rotating shaft is connected to the output shaft of the driver 2, and the other end of the rotating shaft is connected to the second brush head 12. The first bristles are mounted on the shaft body of the rotating shaft. The second brush head 12 includes a turntable and a second brush bristle. The turntable is fixed to the other end of the rotating shaft, and the second brush bristle is disposed on the outside of the turntable. Both the first brush bristle and the second brush bristle can abut against the surface of the cable.

[0024] Specifically, in this embodiment, both the rotating shaft and the turntable are made of wear-resistant and corrosion-resistant materials; the first and second brush bristles in this embodiment are made of highly elastic and tough fiber materials.

[0025] By dividing the cleaning brush head 1 into a first brush head 11 and a second brush head 12, the driver 2 rotates while driving the first brush head 11 to roll and the second brush head 12 to rotate. The first brush head 11 can roll and clean the cable surface, and the second brush head 12 can rotate and clean the cable surface, thereby achieving comprehensive cleaning of the cable surface.

[0026] Optionally, round shafts are provided at both ends of the rotating shaft, with the diameter of the round shafts being larger than the diameter of the rotating shaft, and both the round shafts and the shaft bodies of the rotating shafts are provided with first bristles.

[0027] Optionally, a groove is formed between the two round shafts and the rotating shaft, and the first bristle has a structure with convex ends and a concave middle, with the concave middle position used to clamp the cable.

[0028] By setting round shafts at both ends of the rotating shaft, a groove is formed between the two round shafts and the rotating shaft, and the two ends of the first brush bristles are raised and the middle is recessed. When the first brush head 11 is used to clean the surface of the cable, the cable can be locked in the groove and the recessed position of the first brush bristles. As the driver 2 drives the first brush head 11 to rotate, the first brush head 11 can roll on the surface of the cable, thereby achieving cleaning of the cable surface.

[0029] Optionally, the gas control valve 41 is provided with an air intake knob 411 for controlling the air intake flow rate.

[0030] By setting an air intake knob 411 on the gas control valve 41, the flow rate of compressed air entering the driver 2 can be precisely controlled, thereby controlling the rotation speed of the driver 2 and achieving different speeds for cleaning cables with different levels of dirt.

[0031] Optionally, a filter screen is provided inside the gas control valve 41 to filter impurities and dust inside the compressed air.

[0032] By installing a filter screen inside the gas control valve 41, impurities and dust inside the compressed air can be filtered out. Since both the air inlet pipe 42 and the air return pipe 43 are made of transparent plastic hoses, the accumulation of impurities and dust inside the pipes can be observed directly, thereby determining whether the filter screen needs to be cleaned or replaced.

[0033] Optionally, it also includes an air collection hood 5, which is installed between the cleaning brush head 1 and the driver 2. The bottom of the air collection hood 5 is connected to a connector 45, and the other end of the return air pipe 43 passes through the handle 3 and is connected to the connector 45 at the bottom of the air collection hood 5.

[0034] Specifically, in this embodiment, the gas collecting hood 5 is fitted onto one end of the shaft of the first brush head 11.

[0035] By setting an air collection hood 5 between the driver 2 and the cleaning brush head 1, and connecting the other end of the return air pipe 43 to the air collection hood 5, the exhaust gas generated by the rotation of the driver 2 can be blown to the cleaning brush head 1 through the air collection hood 5. At the same time, it can also blow away the dust attached to the cable surface and the floating dust after cleaning from the cable surface, thereby achieving the cleaning effect on the cleaning brush head 1 and the cleaning effect on the cable surface, and improving the cleaning efficiency of the cable surface.

[0036] Optionally, one end of the air collection hood 5 is configured as a grooved end 51, the diameter of the grooved end 51 of the air collection hood 5 is larger than the diameter of the non-grooved end 52, the grooved end 51 is sleeved on the outer periphery of the cleaning brush head 1, and the non-grooved end 52 of the air collection hood 5 is connected to the driver 2.

[0037] By setting one end of the air collection hood 5 as a groove end 51, and making the diameter of the groove end 51 larger than the diameter of the non-grooved end 52, the air collection hood 5 is made into a trumpet shape. During the process of the exhaust gas blowing towards the cleaning brush head 1 and the process of the exhaust gas blowing towards the cleaning brush head 1 to clean the surface of the cable, the blowing area is larger, which further improves the cleaning efficiency.

[0038] Optionally, it also includes a seal, which is fitted between the return air pipe 43 and the handle 3.

[0039] Specifically, a through hole is provided on the side of the handle 3, and the other end of the return air pipe 43 passes through the through hole and is connected to the connector 45 of the air collection hood 5. The seal is installed at the through hole.

[0040] Furthermore, this application also includes a sealing ring 6, which is fitted around the outer periphery of the connector 45 connected to the exhaust port of the gas control valve 41 and installed inside the handle 3.

[0041] By setting a seal, the return air pipe 43 can be fixed at the opening, and the inner wall of the opening can be prevented from damaging the return air pipe 43.

[0042] By setting a sealing collar 6, the interface connected to the exhaust port of the gas control valve 41 can be fixed inside the handle 3.

[0043] In summary, by configuring a cleaning brush head 1, a driver 2, and a pneumatic assembly 4, compressed air is used to drive the driver 2 to rotate, which in turn drives the cleaning brush head 1 to rotate, thereby achieving the cleaning of the cable surface. The entire process requires no electricity, making it energy-saving, environmentally friendly, and safer. By setting up an air collection hood 5, and connecting the other end of the return air pipe 43 to the air collection hood 5, the exhaust gas generated by the rotation of the driver 2 can be blown through the air collection hood 5 to the cleaning brush head 1 and the cable surface, achieving not only the cleaning effect on the cleaning brush head 1 but also the cleaning effect on the cable surface, thus improving the cleaning efficiency of the cable surface.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
