Description

Technical Field

[0001] The utility model relates to the technical field of weak current equipment maintenance, in particular to a maintenance device for a weak current self-cleaning system. Background Technique

[0002] Weak current refers to the part of the power system with relatively low voltage and current, which is usually used for transmitting and controlling signals, data, and power supply for low-power devices. Corresponding to strong current (high voltage, large current), weak current usually involves relatively low voltage and current, generally in the voltage range below 50 volts. The weak current system includes, but is not limited to, communication systems, computer networks, security monitoring systems, audio and video systems, etc., which are used for transmitting voice, images, data, control signals, etc. The weak current system can also provide the power supply required by low-power devices (such as sensors, cameras, displays, etc.).

[0003] An existing weak current engineering security monitoring device (Publication No.: CN219943767U) has at least the following drawbacks: The above device sets a cleaning brush on the glass of the camera, and drives the cleaning brush to rotate on the glass of the camera through a motor to achieve the cleaning and maintenance of the camera. However, after the cleaning brush is used for cleaning multiple times, it will be covered with dust and the cleaning effect will become poor, and the cleaning brush needs to be cleaned or replaced, so manual cleaning and replacement of the cleaning brush are required frequently, increasing the labor cost. Therefore, the present utility model is proposed. Content of the Utility Model

[0022] Refer to Figure 1 - The figure, a weak current self-cleaning system maintenance device, includes a camera 1. A cleaning and maintenance component is arranged on the top surface of the camera 1. The cleaning and maintenance component includes two fixing blocks 2 fixed on the top surface of the camera 1 near the left and right sides. A cleaning strip 201 is rotatably connected between the two fixing blocks 2. A retaining strip 203 is fixed inside the cleaning strip 201. A cleaning cloth 202 is arranged inside the cleaning strip 201. The cleaning cloth 202 is arranged along the gap between the retaining strip 203 and the inside of the cleaning strip 201. A support strip 206 is arranged on the inner side of the cleaning cloth 202. The support strip 206 is made of PVC material.

[0023] In this embodiment, two drive shafts 204 are rotatably connected to one side inside the cleaning strip 201. A winding roller 205 is arranged on the slidable side of the outer wall of the drive shaft 204. Both ends of the cleaning cloth 202 are wound on the outer walls of the two winding rollers 205 respectively. A first motor is fixed to one side of the cleaning strip 201. The first motor has a self-locking function. The output shaft of the first motor penetrates through one side of the cleaning strip 201 and is fixed to one end of one of the drive shafts 204. A second motor is fixed to one side of one of the two fixing blocks 2. The second motor has a self-locking function. The output shaft of the second motor penetrates through one side of the fixing block 2 and is fixed to the outer wall of the cleaning strip 201. By arranging the cleaning strip 201 on the glass outer wall of the camera 1 and driving the cleaning strip 201 to rotate repeatedly on the glass outer wall of the camera 1, the cleaning cloth 202 inside the cleaning strip 201 can clean and maintain the glass outer wall of the camera 1. At the same time, a support strip 206 made of PVC material is arranged on the inner layer of the cleaning cloth 202, which can support the cleaning cloth 202 to keep the cleaning cloth 202 from deforming. At the same time, the cleaning cloth 202 and the support strip 206 can be wound and unwound by the two winding rollers 205, so that after the cleaning cloth 202 cleans the glass outer wall of the camera 1, the part of the cleaning cloth 202 stained with dust is automatically wound up, and a clean cleaning cloth 202 is automatically released, so that the staff does not need to replace the cleaning cloth 202 frequently, reducing the labor cost.

[0024] In this embodiment, a disassembly and assembly plate 3 is arranged on one side of the cleaning strip 201. A plurality of bolts are slidably inserted into one side of the disassembly and assembly plate 3. One end of the bolt is threadedly connected to one side of the retaining strip 203. By arranging the disassembly and assembly plate 3, the winding roller 205, the cleaning strip 201 and the cleaning cloth 202 can be disassembled and replaced by removing the disassembly and assembly plate 3.

[0025] In this embodiment, first roller bearings 4 are fixed at both ends of the cleaning strip 201 near the retaining strip 203. A second roller bearing 401 is fixed at the corner where the cleaning cloth 202 turns to the winding roller 205 inside the cleaning strip 201. Through the setting and use of the first roller bearing 4 and the second roller bearing 401, a supporting effect can be achieved at the corner of the cleaning cloth 202 to prevent the cleaning cloth 202 from rubbing against the inside of the cleaning strip 201 and causing damage to the cleaning cloth 202.

[0026] In this embodiment, a sponge strip 5 is adhered between the cleaning cloth 202 and the support strip 206. Through the setting and use of the sponge strip 5, the cleaning cloth 202 can be flexibly attached to the glass outer wall of the camera 1, ensuring that the cleaning cloth 202 is closely attached to the glass outer wall of the camera 1.

[0027] In this embodiment, gears 6 are fixed to one ends of the two driving shafts 204 and the winding rollers 205. The two gears 6 are in meshing transmission through a toothed belt. One side of the gear 6 is in contact with one side of the disassembly and assembly plate 3. By providing the gear 6 and cooperating with the toothed belt, the two winding rollers 205 can rotate synchronously, maintaining one winding and one releasing of the cleaning cloth 202, ensuring that the cleaning cloth 202 is in a taut state inside the cleaning strip 201, and ensuring the cleaning effect on the camera 1.

[0028] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: During use, the second motor is started to drive the cleaning strip 201 to rotate forward and backward, so that the cleaning strip 201 rotates repeatedly on the glass outer wall of the camera 1. As a result, the cleaning cloth 202 inside the cleaning strip 201 cleans and maintains the glass outer wall of the camera 1. After the cleaning and maintenance are completed, the cleaning cloth 202 that is in contact with the glass outer wall of the camera 1 is covered with dust. At this time, the first motor is started to drive the driving shaft 204 to rotate, and the driving shaft 204 drives the winding roller 205 to rotate. Since the two gears 6 are in meshing transmission through a toothed belt, the two winding rollers 205 rotate synchronously, thereby winding and releasing the two ends of the cleaning cloth 202, causing the cleaning cloth 202 covered with dust to move into the cleaning strip 201 and be wound up by the winding roller 205, while the clean cleaning cloth 202 moves to the position in contact with the glass outer wall of the camera 1, thus completing automatic cleaning and automatic replacement of the cleaning cloth 202. By providing the disassembly and assembly plate 3, the winding roller 205 can be disconnected from the cleaning strip 201 and the cleaning cloth 202 and disassembled and replaced by disassembling the disassembly and assembly plate 3. Through the setting and use of the first roller bearing 4 and the second roller bearing 401, a supporting effect can be achieved at the corner of the cleaning cloth 202, preventing the cleaning cloth 202 from rubbing against the inside of the cleaning strip 201 and causing damage to the cleaning cloth 202. Through the setting and use of the sponge strip 5, the cleaning cloth 202 can be in flexible contact with the glass outer wall of the camera 1, ensuring that the cleaning cloth 202 is in close contact with the glass outer wall of the camera 1. By providing the gear 6 and cooperating with the toothed belt, the two winding rollers 205 can rotate synchronously, maintaining one winding and one releasing of the cleaning cloth 202, ensuring that the cleaning cloth 202 is in a taut state inside the cleaning strip 201, and ensuring the cleaning effect on the camera 1. A support strip 206 made of PVC material is provided on the inner layer of the cleaning cloth 202, which can support the cleaning cloth 202 and keep the cleaning cloth 202 from deforming.
