Description

Technical Field

[0001] This utility model relates to the field of chemical cleaning technology, specifically a benzene tank unmanned cleaning device. Background Technology

[0002] Cleaning benzene tanks is an essential part of using oil tanks. After prolonged use, a large number of deteriorated products will accumulate inside the benzene tank. These deteriorated products will gradually corrode the benzene tank and reduce its service life. Therefore, benzene tanks need to be cleaned after prolonged use. The existing cleaning method usually involves manual entry into the benzene tank for cleaning. However, manual cleaning is highly dangerous and poses a significant threat to the health of personnel.

[0003] A benzene tank cleaning device disclosed in Chinese Invention Patent Application Publication CN217616650U includes: a support, a moving tube, and a rotating tube; a drive motor is fixedly mounted on the support; the moving tube is slidably mounted on the support without rotation, and a first bevel gear and a second bevel gear are rotatably mounted on the support, the first bevel gear and the second bevel gear meshing with each other; the output shaft of the drive motor is fixedly connected to the second bevel gear; both the moving tube and the first bevel gear are threaded, and the first bevel gear is threadedly connected to the moving tube; several turbines are rotatably mounted inside the moving tube, and the rotating tube is rotatably mounted inside the moving tube without leakage, with one end fixedly connected to the lowest turbine; several clearances are provided on the side wall of the rotating tube; the clearances are used to connect the inner and outer sides of the rotating tube; a cleaning device is fixedly mounted on the other end of the rotating tube, and the cleaning device is used to clean the inner wall of the benzene tank;

[0004] This invention allows for thorough cleaning of the benzene container's interior by moving it up and down simultaneously, eliminating blind spots. It features a simple structure and low manufacturing cost. Due to the large size of benzene containers, existing devices can only clean by moving up and down, requiring sufficiently high hydraulic pressure to reach distant sidewalls. The same pressure would damage nearby sidewalls. Therefore, a device that moves within the benzene container for cleaning is necessary. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a benzene tank unmanned cleaning device, which solves the problem mentioned in the background technology that the device cannot move freely inside the benzene tank.

[0006] Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a benzene tank unmanned entry cleaning device, including a cleaning device, a fixed platform fixedly installed at the bottom of the cleaning device, a rotating ring rotatably connected to the outer surface of the fixed platform, an electromagnetic telescopic sleeve fixedly installed on the outer surface of the rotating ring, a gear ring fixedly installed on the upper surface of the rotating ring, a power source fixedly installed at the bottom of the fixed platform, the power source driving the gear ring to rotate, and electromagnetic adsorption rings fixedly installed at the bottom of the fixed platform and the free end of the electromagnetic telescopic sleeve.

[0008] Furthermore, the electromagnetic adsorption ring includes an electromagnetic ring and a rubber sleeve wrapped around the outer surface of the electromagnetic ring, with a patterned bottom end of the rubber sleeve.

[0009] Furthermore, the bottom end of the fixed platform is provided with an annular groove, the rotating ring is rotatably connected inside the annular groove, and a baffle is provided at the bottom end of the fixed platform below the rotating ring. The middle part of the baffle is threadedly connected to the fixed platform by bolts.

[0010] Furthermore, the power source includes a gearbox, which is fixedly connected to a fixed platform. A gear is fixedly installed at the output end of the gearbox, and a motor is fixedly installed at the input end of the gearbox.

[0011] Furthermore, the electromagnetic telescopic sleeve includes a fixed end and a sliding end. The fixed end is rotatably connected to the rotating ring, and the sliding end is slidably connected to the outer surface of the fixed end. An electromagnetic plate is fixedly installed on the side of the sliding end and the fixed end that are close to each other.

[0012] Furthermore, a positioning plate is fixedly installed on the outer surface of the fixed end near the rotating ring, a limit groove is formed on the outer surface of the fixed end, and a protrusion adapted to the limit groove is fixedly installed inside the sliding end.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The benzene tank is not entered by personnel in the cleaning device. When movement is required, the electromagnetic adsorption ring at the bottom of the electromagnetic telescopic sleeve stops receiving power, driving the gear ring to rotate, causing the electromagnetic telescopic sleeve to point in the desired direction of movement. This energizes the electromagnetic plate, causing the sliding end to extend outward to the designated position, and energizing the electromagnetic adsorption ring at that position. At this time, the electromagnetic telescopic sleeve under the fixed platform stops receiving power, and the electromagnetic plate changes the current direction, causing the electromagnetic plates to attract each other, thereby enabling the entire cleaning device to move. This design allows the device to move like a polar coordinate system, solving the problem of existing cleaning devices being unable to move freely.

[0015] 2. The benzene tank cleaning device is designed for unmanned entry. A ring groove is provided at the bottom of the fixed platform, and a rotating ring is rotatably connected inside the ring groove. A baffle is provided at the bottom of the fixed platform below the rotating ring. The middle part of the baffle is threadedly connected to the fixed platform by bolts. This design allows the rotating ring to be engaged inside the ring groove, which facilitates the assembly of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1-4 A benzene tank unmanned cleaning device includes a cleaning device 1. A fixed platform 2 is fixedly installed at the bottom of the cleaning device 1. A rotating ring 3 is rotatably connected to the outer surface of the fixed platform 2. An electromagnetic telescopic sleeve 4 is fixedly installed on the outer surface of the rotating ring 3. A gear ring 5 is fixedly installed on the upper surface of the rotating ring 3. A power source 6 is fixedly installed at the bottom of the fixed platform 2, driving the gear ring 5 to rotate. Electromagnetic adsorption rings 7 are fixedly installed at the bottom of the fixed platform 2 and the free end of the electromagnetic telescopic sleeve 4. The water supply pipe, the control electromagnetic part, the power cord, and the control line of the cleaning device together constitute the traction of the device, thereby enabling the device to be reset by traction.

[0023] The electromagnetic adsorption ring 7 includes an electromagnetic ring 701 and a rubber sleeve 702 wrapped around the outer surface of the electromagnetic ring 701. The bottom end of the rubber sleeve 702 is patterned. Since the inner wall of the benzene can is coated, the rubber sleeve 702 can reduce damage to the benzene can coating.

[0024] The bottom end of the fixed platform 2 is provided with an annular groove 201, and the rotating ring 3 is rotatably connected inside the annular groove 201. The bottom end of the fixed platform 2 is provided with a baffle 202 below the rotating ring 3. The middle part of the baffle 202 is threadedly connected to the fixed platform 2 by a bolt 203. This arrangement can lock the rotating ring 3 inside the annular groove 201, which facilitates the assembly of the device.

[0025] The power source 6 includes a gearbox 601, which includes at least a worm gear self-locking unit with transmission connection and a gear transmission reduction unit. The gearbox 601 is fixedly connected to the fixed platform 2. A gear 602 is fixedly installed at the output end of the gearbox 601, and a motor 603 is fixedly installed at the input end of the gearbox 601. With this configuration, the gear ring 5 can be driven to rotate, thereby changing the forward direction of the device.

[0026] The electromagnetic telescopic sleeve 4 includes a fixed end 401 and a sliding end 402. The fixed end 401 is rotatably connected to the rotating ring 3, and the sliding end 402 is slidably connected to the outer surface of the fixed end 401. An electromagnetic plate 403 is fixedly installed on the side of the sliding end 402 and the fixed end 401 that are close to each other. The telescopic state of the electromagnetic telescopic sleeve 4 can be changed by controlling the current direction of the electromagnetic plates 403 on both sides.

[0027] A positioning plate 404 is fixedly installed on the outer surface of the fixed end 401 near the rotating ring 3. A limiting groove 405 is formed on the outer surface of the fixed end 401. A protrusion 406 adapted to the limiting groove 405 is fixedly installed inside the sliding end 402. This setting can limit the displacement distance of the sliding end 402.

[0028] In use, the cleaning device 1 sprays cleaning fluid to clean the inside of the benzene tank. When movement is required, the electromagnetic adsorption ring 7 at the bottom of the electromagnetic telescopic sleeve 4 stops receiving power, driving the gear ring 5 to rotate, so that the electromagnetic telescopic sleeve 4 points in the direction to be moved, and energizes the electromagnetic plate 403, so that the sliding end 402 extends outward to the designated position, and energizes the electromagnetic adsorption ring 7 at that position. At this time, the electromagnetic telescopic sleeve 4 under the fixed platform 2 stops receiving power, and the electromagnetic plate 403 changes the current direction so that the electromagnetic plates 403 attract each other, thereby enabling the cleaning device 1 to move as a whole. This setting allows the device to move like a polar coordinate system.
