[0038] Embodiment 1, see Figures 1-6 :

[0039] A current collector 1 with a cleaning device, comprising a current collector 1, a containing portion 2 is concavely arranged at the bottom of the current collector 1, the containing portion 2 is used for installing a scraping strip 4, the scraping strip 4 and a current collector brush 10 of the current collector 1 are arranged at the bottom of the current collector 1 in parallel, and the end of the scraping strip 4 and the end of the current collector brush 10 are located at the same horizontal height. It can be understood that the width of the containing portion 2 is not less than the width of the scraping strip 4.

[0040] The bottom of the scraping strip 4 is provided with a plurality of wire grooves corresponding to the slide wire part 11, and a convex point 40 is arranged between adjacent wire grooves, and the convex point 40 contacts the slide wire part 11. It can be understood that the lower end surface 42 of the convex point 40 and the end of the current collector brush 10 are located at the same horizontal height.

[0041] The scraping strip 4 is installed on the fixed support 3, the upper part of the fixed support 3 is provided with an elastic member, the elastic member is connected to the accommodating part 2, and the two sides of the fixed support 3 are detachably installed on the accommodating part 2. With the working of the current collector 1, the scraping strip 4 cleans and scrapes off the impurities on the slide wire part 11, thereby reducing the poor contact between the slide wire and the current collector 1 due to impurities. The scraping strip 4 is continuously worn out during work, so that the scraping strip is from the initial state to the worn state, and the elastic member applies a downward restoring force to the scraping strip 4, so that the convex point 40 of the scraping strip 4 is in contact with the slide wire part 11, avoiding the scraping strip 4 from being worn to a certain extent and causing the cleaning performance to be reduced or even invalid. Finally, until the scraping strip 4 is excessively worn, the excessively worn scraping strip 4 is removed and replaced with a new scraping strip 4.

[0042] As an embodiment, the fixed support 3 is provided with a buckle part 30 on the two sides, the accommodating part 2 is provided with a buckle positioning through hole 20 corresponding to the buckle part 30 on the two sides, and when the fixed support 3 is installed, the buckle part 30 is placed in the corresponding buckle positioning through hole 20. The through hole structure is adopted to facilitate the dismounting of the fixed support 3 and the replacement of the excessively worn scraping strip 4.

[0043] As an embodiment, the fixed support 3 is provided with an extension part 31 inwardly arranged on the two sides of the lower part, and the scraping strip 4 is provided with a mounting groove 41 for accommodating the extension part 31. When the scraping strip 4 is installed, the extension part 31 of the fixed support 3 is aligned and inserted into the mounting groove 41 of the scraping strip 4. In order to avoid the scraping strip 4 from falling off during use, the width of the accommodating part 2 is only slightly larger than the width of the scraping strip 4. After the scraping strip 4 is installed in the accommodating part 2, the mounting groove 41 of the scraping strip 4 cannot slide out of the extension part 31. Preferably, the width of the accommodating part 2 is not more than 1.2 times the width of the scraping strip 4.

[0044] As an embodiment, the two extension parts 31 are connected by a baffle 33.

[0045] As an embodiment, the scraping strip 4 is a rubber strip. The rubber strip has good insulation performance, certain elasticity and flexibility, and plays a buffering and wear-resistant role, and is suitable for occasions requiring frequent friction. It can be understood that when the number of the scraping strip 4 is one, the scraping strip 4 is located on the front side or the rear side of the current collector 10.

[0046] As an embodiment, the elastic member is a compression spring 5. When the scraping strip 4 is installed in the accommodating part 2 and the point of the scraping strip 4 is in contact with the slide wire part 11, the compression spring 5 is in a compressed state. The compression spring 5 has a downward restoring force to the scraping strip 4, so that the scraping strip 4 is still in contact with the slide wire part 11 after being worn in the length direction, thereby playing a cleaning role.

[0047] As an embodiment, the number of the compression spring 5 is two, and the compression spring 5 is arranged on the two sides of the upper part of the fixed support 3.

[0048] As an implementation, the bottom of the accommodating part 2 is provided with a mounting column 21, the upper part of the fixed support 3 is arranged with a mounting hole 32, and the two ends of the compression spring 5 are connected to the mounting column 21 and the mounting hole 32 respectively. Preferably, the two ends of the compression spring 5 can be coated with adhesive, and the connection stability is better.

[0049] Embodiment 2, see Figure 7 :

[0050] Embodiment 1 is repeated, but the width of the lower end of the convex point 40 is smaller than the width of the upper end of the convex point 40.

[0051] As an implementation, the cross section of the lower end of the convex point 40 is isosceles trapezoidal, the upper base of the isosceles trapezoidal is smaller than the lower base, and the lower end surface 42 of the convex point 40 is the upper base of the isosceles trapezoidal.

[0052] Embodiment 3, see Figure 8 :

[0053] Embodiment 1 is repeated, but the number of the accommodating part 2 and the corresponding scraping strip 4 is two, and the current collector brush 10 is located between the two scraping strips 4. During the working process of the current collector 1, the front and rear scraping strips 4 have a better cleaning effect on the impurities on the slide wire component 11.

[0054] Embodiment 4, see Figures 9-10 :

[0055] Embodiment 1 is repeated, but the elastic member is not a compression spring 5, but a constant force spring 6.

[0056] As an implementation, the number of the constant force spring 6 is two, the upper part of the fixed support 3 is in contact with the loop curved end 60 of the constant force spring 6, the other end of the constant force spring 6 is mounted at the opening of the accommodating part 2, and the constant force spring 6 applies an elastic restoring force to one end of the scraping strip 4. Since the elastic restoring force of the constant force spring 6 within the effective stroke is a constant value, the scraping strip 4 can maintain stable brush pressure with the slide wire component 11, and avoid excessive wear of the scraping strip 4 caused by excessive brush pressure.
