[0046] In the present utility model, the descriptions involving "first", "second", "upper", "lower", etc. are only for descriptive purposes and cannot be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", "upper", "lower" may explicitly or implicitly include at least one of such features. Additionally, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the technical solutions between embodiments can be combined, they are all within the protection scope required by the present utility model.

[0047] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0048] As Figure 1 shown, a mobile energy storage vehicle includes: a battery energy storage system and a cleaning device 4. The battery energy storage system includes a battery pack composed of a plurality of battery units electrically connected to each other. The battery pack is provided with two main electrodes, and each of the two main electrodes is connected to a cable 3. The other end of the cable 3 is used for electrically connecting to a charging device or a discharging device. The cable 3 telescopically passes through the cleaning device 4. The cleaning device 4 includes: a cleaning mechanism 430, a wiping mechanism 450, and a limiting mechanism. The cleaning mechanism 430 includes multiple groups of bristles, and the bristles are fixed on the inner peripheral wall of a circular hole. Moreover, the cable 3 extends radially towards the center of the circular hole. The wiping mechanism 450 includes a cleaning cloth having a central hole, and the central hole of the cleaning cloth is coaxially arranged with the circular hole of the cleaning mechanism 430. The cable 3 extends outwards from the battery pack through the cleaning mechanism 430 and the wiping mechanism 450. The limiting mechanism includes two rotating rollers 470 arranged at a preset distance from each other in the up and down directions, and the cable 3 passes between the two rotating rollers 470.

[0049] The battery energy storage system includes a battery cabinet. A plurality of battery units are placed on the battery cabinet. Each battery unit forms a battery pack through at least one of series connection and parallel connection. The battery pack has two main output electrodes. The two main electrodes are connected to an external device through a cable 3. The external device can be a charging device and a discharging device. The battery energy storage system supplies power to the discharging device, and when the power is insufficient, the battery pack can be charged through the charging device. The length of the cable 3 can be selected according to needs to meet the electrical connection requirements in most working conditions. When the cable 3 is in use, it will adhere to soil, sand, or other impurities. Due to the length of the cable 3, it is very laborious to clean, wasting manpower and material resources and unable to achieve a satisfactory effect. Therefore, the cleaning device 4 is provided. After the cleaning mechanism 430 sweeps away the soil, sand, and impurities on the cable 3, the wiping mechanism 450 can wipe the cable 3 to keep the cable 3 clean. The cable 3 passes through the central hole of the cleaning cloth and the end of the brush. When the cable 3 expands and contracts, it will shake, resulting in uneven cleaning and wiping, and the brush will also damage the surface of the cable 3. Therefore, the cable 3 is limited by the limiting mechanism to prevent the cable 3 from shaking greatly in the up and down directions.

[0050] With the mobile energy storage vehicle having the above structure, when the cable 3 is wound up, abrasion and dirt of the cable 3 are avoided, and it is not easy to affect the smooth operation of the cable 3 reel. When cleaning the surface of the cable 3, the labor intensity of the staff is reduced, saving time and effort.

[0051] Further, the cleaning device 4 further includes: a housing, including a housing body 410 and a cover plate 420 fastened to one end of the housing body 410. The housing body 410 is cylindrical, the cleaning mechanism 430 and the wiping mechanism 450 are sequentially fixed on the inner sidewall of the housing body 410 along the axial direction, and the limiting mechanism is fixed on the inner sidewall of the housing body 410 at one end of the housing body 410 close to the battery energy storage system.

[0052] The housing body 410 can preferably be a square or circular cylinder, with both ends of the housing body 410 being open, and one end being fastened by an end cover. The cleaning mechanism 430, the wiping mechanism 450, and the limiting mechanism are all fixed on the inner sidewall of the housing body 410. The cleaning mechanism 430, the wiping mechanism 450, and the limiting mechanism can be sequentially fixed in the order from far away from the battery energy storage system to close to the battery energy storage system. When the cable 3 passes through the housing body 410, it is first limited by two rotating rollers 470 to prevent the extended section of the cable 3 from shaking. When cleaning the cable 3, first brush off the soil, sand, and other impurities on the surface of the cable 3 with a brush, and then wipe it with a rag.

[0053] Further, fixing grooves are respectively provided at both ends in the diameter direction of the inner sidewall of the housing body 410. The cleaning mechanism 430 further includes a cleaning frame, and the round hole is provided at the center of the cleaning frame. The wiping mechanism 450 further includes a wiping frame, and the rag is fixed through the wiping frame. Fixing blocks are respectively provided on two opposite frames of the cleaning frame and the wiping frame in opposite directions, and the fixing blocks cooperate with the fixing grooves.

[0054] Preferably, the fixing groove is a T-shaped groove 411, the T-shaped groove 411 has an opening at one end of the housing body 410 close to the cover plate 420, and the fixing block is a T-shaped block 460. During installation, the wiping mechanism 450 and the cleaning mechanism 430 are sequentially pushed into the T-shaped groove 411, and then the cover plate 420 is fixed. The length of the T-shaped groove 411 is less than the thickness of the cleaning frame and the wiping frame, and the cleaning mechanism 430 and the wiping mechanism 450 are fixed by the cover plate 420 and the end of the T-shaped groove 411.

[0055] Further, a dust removal port 412 is provided at the bottom of the housing body 410, and a dust collection box 440 communicating with the dust removal port 412 is fixed on the outer peripheral surface of the housing body 410.

[0056] The impurities, soil, sand, etc. removed by the cleaning mechanism 430 fall into the dust collection box 440 under the action of gravity. The dust collection box 440 is detachably installed at the bottom of the housing body 410, facilitating the cleaning of the dust collection box 440. As another implementation manner, the box body 441 of the dust collection box 440 is fixedly installed with the housing body 410, and an openable box cover 442 is provided on the box body 441.

[0057] To facilitate dust collection, a blower can also be installed at the bottom of the dust collection box 440, so that dust falls into the dust collection box 440 under the action of negative pressure. A filter screen is arranged between the blower and the dust collection box 440 to prevent a large amount of dust from falling on the blower.

[0058] Furthermore, the mobile energy storage vehicle further includes: a reel device disposed between the battery energy storage system and the cleaning device 4. The reel mechanism includes a reel, and the cable 3 is wound around the reel.
