Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a cleaning device for a transmission and substation line, comprising a flushing gun 1, a connecting mechanism is arranged at the bottom end of the flushing gun 1, a connecting pipe 3 is hingedly connected to the inner side wall of the connecting mechanism, a slider 4 is slidably connected to the inner wall of the connecting pipe 3, the slider 4 can move along the inner wall of the connecting pipe 3 with a hinged rod 5, the right end of the slider 4 is hingedly connected to a contact plate 6 through the hinged rod 5, the contact plate 6 is arc-shaped, and a cleaning brush is arranged on the inner wall of the contact plate 6, so that the cleaning brush can contact the surface of the line to clean its surface, refer to Figure 4 The inner wall at the top of the slider 4 is elastically connected to a card plate 8 through a return spring 7, and a card slot 9 is provided on the outer wall of the connecting tube 3. The card slot 9 has a horizontal opening and a vertical opening. At this time, the card plate 8 coincides with the vertical opening of the card slot 9, so that the card plate 8 cannot move left and right with the slider 4. When the card plate 8 coincides with the horizontal opening of the card slot 9, the card plate 8 can move left and right with the slider 4.

[0032] Reference Figure 1 and Figure 5The top of the flushing gun 1 is fixedly connected with a fixed block 10, and the fixed block 10 is T-shaped and corresponds to the bottom end of the baffle plate 13, so that the baffle plate 13 can be initially connected to the fixed block 10. The outer wall of the fixed block 10 is elastically connected to the limit block 12 through the positioning spring 11, and the inner wall of the fixed block 10 is plugged with a baffle plate 13. The baffle plate 13 can block water mist to prevent splashing on the face of the staff, and the baffle plate 13 is made of transparent material, so that the staff can observe through the baffle plate 13. The outer wall of the fixed block 10 is fixedly connected to one end of the positioning spring 11. When the limit block 12 moves to the right, the positioning spring 11 will be stretched. When resetting, the elastic force of the positioning spring 11 is used to reset the limit block 12, and the other end of the positioning spring 11 is fixedly connected to the inner side wall of the limit block 12.

[0033] The limit block 12 passes through and is slidably connected to the inner wall of the fixed block 10 . The limit block 12 is plugged into the inner wall of the shielding plate 13 . The outer wall of the shielding plate 13 is provided with a notch corresponding to the limit block 12 , so that the limit block 12 can limit the shielding plate 13 .

[0034] Reference Figure 4 The top inner wall of the slider 4 is fixedly connected to one end of the return spring 7. When the card plate 8 moves upward, the return spring 7 will be compressed. When resetting, the elastic force of the return spring 7 is used to return the card plate 8. The other end of the return spring 7 is fixedly connected to the top of the card plate 8. The card plate 8 is slidably connected to the inner wall of the slider 4, and the card plate 8 is engaged with the inner wall of the slot 9.

[0035] Reference Figure 1-Figure 3 The right end of the slider 4 is hinged to one end of the hinged rod 5. Since the length of the hinged rod 5 is constant, when the slider 4 moves to the left with the hinged rod 5, the hinged rod 5 and the contact plate 6 will move closer to each other. On the contrary, when the slider 4 moves to the right with the hinged rod 5, the hinged rod 5 and the contact plate 6 will be separated from each other. The other end of the hinged rod 5 is hinged to the left end of the contact plate 6. The hinged rod 5 penetrates and is slidably connected to the inner wall of the connecting tube 3. The connecting tube 3 is provided with a notch corresponding to the hinged rod 5. The contact plate 6 is slidably connected to On the inner wall of the connecting tube 3, the connecting mechanism includes a U-shaped rod 2, which mainly supports the connecting tube 3. The U-shaped rod 2 is rotatably connected to the flushing gun 1. When the contact plate 6 contacts the substation line, the flushing gun 1 can rotate left and right to spray flushing water. The inner side wall of the U-shaped rod 2 is hinged to the outside of the connecting tube 3. The above-mentioned U-shaped rod 2, connecting tube 3, hinged rod 5, slider 4 and contact plate 6 are all made of insulating materials, and the surface of the reset spring 7 is coated with an insulating coating, which can reduce the risk of electric shock.

[0036] Working principle: First, when it is necessary to clean the substation line, just place the substation line between the contact plates 6, then move the card plate 8 upward and compress the reset spring 7 to separate the vertical openings of the card plate 8 and the card slot 9, and overlap the horizontal openings of the card plate 8 and the card slot 9, and then move the card plate 8 to the left with the slider 4 and the hinged rod 5, so that the other end of the hinged rod 5 brings the contact plate 6 closer to each other, so that the cleaning brush in the contact plate 6 contacts the surface of the substation line, and finally release the card plate 8 and use the reverse elastic force of the reset spring 7 to reset the card plate 8, so that the card plate 8 is engaged with the vertical opening of the card slot 9, and at this time, start the flushing gun 1 to flush the surface of the substation line with flushing water, and at the same time, the connecting pipe 3 can be moved left and right to move the contact plate 6, so that the cleaning brush on the contact plate 6 cleans the surface of the substation line to avoid stains on the surface of the substation line affecting subsequent use.

[0037] During the use of the flushing gun 1, the baffle plate 13 is used to shield the staff's face to prevent wind from blowing water mist onto the staff's face. When the baffle plate 13 needs to be disassembled, the limit block 12 only needs to be moved to the right and the positioning spring 11 needs to be stretched to separate the limit block 12 from the notch of the baffle plate 13. Then the baffle plate 13 is removed from the fixed block 10. When the baffle plate 13 needs to be installed, the baffle plate 13 only needs to be inserted into the fixed block 10. When the notch of the baffle plate 13 coincides with the limit block 12, the limit block 12 is released and the reverse elastic force of the positioning spring 11 is used to reset the limit block 12, so that the limit block 12 and the notch of the baffle plate 13 are plugged in to limit the entire baffle plate 13.

[0038] After cleaning, you can follow the steps in the first paragraph to separate the vertical opening of the card plate 8 from the card slot 9, and overlap the horizontal openings of the card plate 8 and the card slot 9. The card plate 8 can move to the right with the slider 4 and the hinged rod 5, and the hinged rod 5 can separate the contact plate 6 from each other, so that the cleaning brush no longer contacts the surface of the substation line.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
