Therefore, in addition to the ability to remove large particles, the cleaning equipment needs to be able to move under complex ground conditions and be non-magnetic. Currently, there is no suitable cleaning equipment in China for this scenario. Utility Model Content

[0029] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0030] In view of this, an apparatus for cleaning the bottom of an electrolytic cell is provided according to an embodiment of this application, such as... Figure 1 As shown, the system includes a chassis 1, a cleaning device 2, a conveying device 3, and an anti-magnetic chamber 4. The chassis 1 includes a chassis frame 11 and a first roller 12 installed at the bottom of the chassis frame 11. The cleaning device 2 is fixedly connected to the front end of the chassis frame 11 and is used to transport the cleaned material to the conveying device 3. The conveying device 3 is located in the middle of the chassis frame 11 and is used to transport the cleaned material. An obstacle-crossing mechanism is provided on the conveying device 3. The anti-magnetic chamber 4 is located above the chassis 1 and is used to house control devices.

[0031] Specifically, the first roller 12 can drive the chassis frame 11 and all devices mounted on the chassis frame 11 to move on the ground at the bottom of the electrolytic cell. During this movement, the cleaned material is transported by the cleaning device 2 to the conveying device 3, and then conveyed by the conveying device 3 to the next workstation. The obstacle-crossing mechanism ensures that the conveying device 3 will not be jammed by large particles of cleaned material, preventing the equipment from moving.

[0032] Furthermore, in a specific embodiment, the first roller 12 includes drive wheels symmetrically mounted on both sides of the rear end of the chassis frame 11 and omnidirectional wheels symmetrically mounted on both sides of the front end of the chassis frame 11. To traverse narrow cleaning areas, this application employs a rear-wheel differential drive and front-wheel omnidirectional auxiliary drive system, enabling overall forward, backward, and rotational movement. Additionally, a shock-absorbing spring is provided between the drive wheels and the chassis frame 11 to adapt to various complex ground environments. It should be noted that the drive wheels and omnidirectional wheels can be replaced by other components that achieve the same function, such as steering wheels or tracks, all of which are within the scope of protection of this application.

[0033] Furthermore, in a specific embodiment, the antimagnetic cabin 4 consists of a cabin body, a cabin cover, and a protective plate; the cabin body is fixedly installed on the top of the chassis frame 11 and is used to house control devices; the cabin cover is located above the cabin body and is sealed to the cabin body; the protective plate is located on the side of the cabin body for protection. The cabin body, the cabin cover, and the protective plate are all made of antimagnetic materials, which can isolate interference from strong external magnetic fields.

[0034] Furthermore, in one embodiment, such as Figure 2 As shown, the cleaning device 2 includes a rotary motor 21 and a disc brush 22; a fixed bracket 13 is fixedly connected to the front end of the chassis frame 11; the fixed bracket 13 is connected to the motor bracket 25; the rotary motor 21 is fixed on the motor bracket 25 and connected to the disc brush 22 through the disc brush flange 26.

[0035] Specifically, the disc brush 22 is inclined, meaning that the front end of the disc brush 22 is lower than the rear end, so that the front end of the disc brush 22 fits tightly against the bottom surface under the action of gravity. During operation, the rotary motor 21 drives the disc brush 22 to rotate, and the cleaned object is brought to the rear end of the disc brush 22 by the traction force of the front end of the disc brush 22 and transported to the conveying device 3.

[0036] Furthermore, in specific embodiments, such as Figure 2 As shown, there are two sets of the cleaning device 2, which are symmetrically arranged on both sides of the front end of the chassis frame 11, which can make the cleaning area larger and can clean the corners of the bottom of the electrolytic cell.

[0037] Furthermore, in a specific embodiment, a roller brush is also provided between the disc brush 22 and the conveying device 3 to improve cleaning efficiency.

[0038] Furthermore, in a specific embodiment, an antimagnetic cover made of antimagnetic material is provided on the outside of the rotary motor 21 to shield strong magnetic fields so that the rotary motor 21 can work normally.

[0039] Furthermore, in one embodiment, such as Figure 2 As shown, an adjustment mechanism is provided on the cleaning device 2 to make the disc brush 22 contact the ground; the adjustment mechanism includes a damping hinge 23 and a first spring 24; the fixed bracket 13 is connected to the motor bracket 25 through the damping hinge 23; one end of the first spring 24 is connected to the fixed bracket 13 and the other end is connected to the motor bracket 25, and there are two first springs 24, which are respectively arranged above and below the damping hinge 23.

[0040] Specifically, the damping hinge 23 provides specific resistance to dissipate the energy generated during rotation, while the first spring 24 provides automatically adjustable tension. When encountering uneven ground during operation, the disc brush 22 drives the rotary motor 21 and the motor bracket 25 to rotate together around the damping hinge 23, and then quickly returns to its original position under the action of the first spring 24. This ensures the contact force between the disc brush 22 and the ground while also achieving a shock absorption effect.

[0041] Furthermore, in one embodiment, such as Figure 3 As shown, the conveying device 3 includes a drive motor 31, a drive wheel 32, a driven wheel 33, a conveyor frame 34, and a belt 35. The drive motor 31 is fixedly mounted on the chassis frame 11 and is connected to the drive wheel 32 via a synchronous belt 311. The drive wheel 32 is fixedly mounted on the top of the chassis frame 11 at the end away from the sweeping device 2 and is rotatably connected to one end of the conveyor frame 34. The end of the conveyor frame 34 away from the drive wheel 32 is close to the bottom of the sweeping device 2 and is rotatably connected to the driven wheel 33. The belt 35 is wound around the conveyor frame 34, the drive wheel 32, and the driven wheel 33.

[0042] Specifically, the drive motor 31 drives the drive wheel 32 to rotate via the synchronous belt 311, thereby causing the belt 35 to rotate around the drive wheel 32 and the driven wheel 33. At the same time, the cleaned items transported onto the belt 35 are also conveyed to the other end of the belt 35 as the belt 35 rotates, and enter the next work station.

[0043] Furthermore, in a specific embodiment, an antimagnetic cover made of antimagnetic material is provided on the outside of the drive motor 31 to shield strong magnetic fields so that the drive motor 31 can work normally.

[0044] Furthermore, in one embodiment, such as Figure 3As shown, the obstacle-crossing mechanism includes a guide roller 36, a guide bracket 37, and a second spring 38; the guide bracket 37 is fixedly mounted on the chassis frame 11 near the cleaning device 2, and a longitudinal guide groove 371 is provided on the guide bracket 37; the guide roller 36 is connected to the side of the conveyor frame 34 near the driven wheel 33 and is inserted into the guide groove 371; the bottom end of the second spring 38 is connected to the chassis frame 11, and the top end is connected to the conveyor frame 34.

[0045] Specifically, because the drive wheel 32 is rotatably connected to the conveyor frame 34, the conveyor frame 34 can drive the driven wheel 33 and the belt 35 to rotate around the drive wheel 32 as a whole. In actual operation, when the bottom of the conveying device 3 encounters a protruding obstacle, the conveyor frame 34 overcomes the clamping force of the second spring 38 and lifts around the drive wheel 32, thereby overcoming the obstacle; then it returns to its original position under the action of the second spring 38. At this time, the guide roller 36 slides accordingly in the guide groove 371, thus limiting the movement of the conveyor frame 34.

[0046] Furthermore, in a specific embodiment, to enhance the recovery capability of the obstacle-crossing mechanism, two second springs 38 are provided, respectively located on both sides of the guide groove 371. Additionally, the bottom ends of both second springs 38 are connected to the top end of the guide bracket 37, and the length of the second springs 38 is shortened to increase the tension force.

[0047] Furthermore, in one embodiment, such as Figure 3 As shown, first guardrails 351 are provided on both sides of the belt 35, and multiple guardrails 352 are provided between the two first guardrails 351.

[0048] Specifically, the first guard 351 can prevent the cleaned material from falling off the sides of the belt 35; the guard strip 352 can prevent the cleaned material from sliding down the belt 35 when it is being transported from a low position to a high position, thereby improving the transport efficiency.

[0049] Furthermore, in one embodiment, such as Figure 3 As shown, a guide ramp 353 and a transition strip 354 are provided at one end of the belt 35 near the cleaning device 2; the guide ramp 353 is fixed on the chassis frame 11, and one end of the guide ramp 353 is close to the bottom of the cleaning device 2, while the other end is connected to the transition strip 354; the transition strip 354 is placed on the belt 35.

[0050] Specifically, because the end of the belt 35 has a certain thickness, it cannot be directly inserted into the bottom of the rear end of the disc brush 22 to receive the cleaned material. Therefore, the guide ramp 353 is provided. The guide ramp 353 can be directly inserted into the bottom of the rear end of the disc brush 22. The cleaned material can be easily transported onto the guide ramp 353 under the traction of the disc brush 22, and then pushed onto the belt 35 by the transition strip 354.

[0051] Furthermore, in a specific embodiment, in order to prevent the cleaned material from falling off both sides of the guide ramp 353, a second retaining edge is also provided on both sides of the guide ramp 353.

[0052] Furthermore, in one embodiment, such as Figure 1 As shown, the device also includes a collection device 5 for holding the cleaned items conveyed by the conveying device 3; the collection device 5 includes a housing 51 and a second roller 52 installed at the bottom of the housing 51; the housing 51 is detachably connected to the rear end of the chassis frame 11 and is located below the end of the belt 35 near the housing 51.

[0053] Specifically, when the cleaned item is transported to one end of the belt 35 near the housing 51, it falls into the housing 51 under the action of gravity, effectively increasing the storage capacity of the housing 51 and further improving the cleaning range.

[0054] Furthermore, in a specific embodiment, the second roller 52 includes fixed wheels symmetrically installed on both sides of the front end of the housing 51 and omnidirectional wheels symmetrically installed on both sides of the rear end of the housing 51.

[0055] Preferably, in a specific embodiment, a clamp is provided on the side of the housing 51 near the chassis frame 11, and the clamp is connected to the rear end of the chassis frame 11 via a latch. It should be noted that any technical solution that allows for the detachable connection of the housing 51 and the chassis frame 11 is within the scope of the claimed protection.

[0056] Furthermore, in one embodiment, such as Figure 1 As shown, an infrared sensor 53 is also provided on the upper side wall of the housing 51. Specifically, the infrared sensor 53 tilts downwards to illuminate the interior of the housing 51 to determine the remaining capacity of the housing 51.

[0057] Furthermore, in one embodiment, a telescopic electric cylinder is also provided between the disc brush 22 and the disc brush flange 26. Specifically, the telescopic electric cylinder can drive the disc brush 22 to rise or fall. When the disc brush 22 rises to the high position, it is in a walking state, at which time the device can move without cleaning; when the disc brush 22 falls to the low position, it is in a cleaning state, at which time the device can move and clean.

[0058] Furthermore, in a specific embodiment, an antimagnetic cover made of antimagnetic material is also provided on the outside of the telescopic electric cylinder to shield strong magnetic fields so that the telescopic electric cylinder can work normally.

[0059] Preferably, in a specific embodiment, the chassis frame 11 is a square tube steel frame to ensure the overall stability of the equipment.
