The following describes the preferred embodiments of the present invention in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so that the protection scope of the present invention is more clearly defined .

As shown in Figure 1-4, it is a power supply for a foreign object laser removal instrument of a transmission line according to the present invention, which includes a box with an opening at the top, a cover 5 that covers the opening, and a power supply The body 9 and the bottom of the box 1 are provided with supporting feet. A number of first heat dissipation holes 11 are processed on the bottom of the box 1, a horizontal support plate 2 is provided in the box 1, a power supply body 9 is placed on the support plate 2, and a number of electric pushers are fixed on the inner bottom wall of the box 1 The movable end of the rod 23 and the electric push rod 23 is connected to the support plate 2 to drive the support plate 2 to move up and down. A pillar 24 corresponding to the first heat dissipation hole 11 is installed at the bottom of the support plate 2, and the outer dimension of the pillar 24 is adapted to the outer dimension of the first heat dissipation hole 1. When the support plate 2 moves downward, the pillar 24 The first heat dissipation hole 11 is tightly connected to seal the first heat dissipation hole 11. A horizontal positioning plate 3 is movably installed in the cabinet 1 above the power supply body 9. The sides around the positioning plate 3 are in contact with the inner side wall of the cabinet 1 and can slide up and down along the side wall of the cabinet 1. The positioning plate 3 It can be removed from the opening by sliding it up a certain distance. A rubber layer 31 for cushioning is attached to the lower surface of the positioning plate 3. The lower surface of the positioning plate 3 is located on the outer side of the power supply body 9 and a vertical plate 4 is installed. Preferably, the vertical plate 4 is provided on each of the four sides of the front, rear, left, and right sides of the power supply body 9. A plug block 41 is installed on the side of the power supply body 9, and a plug slot (not shown in the figure) is opened on the plug block 41 in a direction perpendicular to the vertical plate 4, and a plug rod 42 is slidably inserted in the plug slot , A first spring 43 is installed in the insertion slot between the end of the insertion rod 42 and the bottom of the insertion slot, and the end of the insertion rod 42 away from the first spring 43 is provided with a vertical clamping plate 44 which is close to The side surface of the power supply body 9 is in contact with the outer surface of the power supply body 9. Through the above structural design, when the support plate 2 moves upward, the power supply body 9 and the movable plate 3 move upward as a whole, and the first heat dissipation hole 11 is in an open state, which is convenient for ventilation and heat dissipation, and at the same time, the power supply body 9 can be well positioned To prevent it from shaking during transportation. At the same time, when the support plate 2 moves downward, the cylinder 24 seals the first heat dissipation hole 11 so that the inside of the power supply is in a sealed state, and water, dust, etc. are not easy to enter. It should be noted that since the clamping plate 44 and the plug rod 42 are installed in a plug-in manner, when targeting the power supply body 9 of different sizes, the power supply body 9 of different sizes can be adapted by replacing the clamping plate 44 and the plug lever 42 Fixed demand.

Wherein, one end of the cover body 2 is hinged to one end of the box body 1, and the other end of the cover body 2 is detachably connected to the box body 1. An elongated slide groove 51 is opened in the cover body 2 in a direction perpendicular to the cover body 2. A slide 61 is slidably installed in the slide groove 51. The slide groove 51 is located between the bottom of the slide groove 51 and the slide 61. There is a second spring 6, a movable rod 62 is installed at the bottom of the slider 61, an end of the movable rod 62 away from the slider 61 penetrates through the bottom of the cover 2, and a pressure plate 63 is installed at the end of the movable rod 62 away from the slider 61, When the cover 2 is closed on the opening, the lower surface of the pressing plate 63 is in contact with the upper surface of the positioning plate 3. Through the above structural design, when the support plate 2 moves upward or downward, the pressure plate 63 can drive the positioning plate 3 to always contact the top of the power supply body 9 through the action of the second spring 6, thereby further preventing the power supply from shaking and improving the power supply Use effect.

Among them, in order to improve the overall intelligence of the power supply, the power supply body 9 includes a controller for controlling the opening and closing of the electric push rod 23, a sensor assembly for detecting surrounding environmental parameters, and a lithium battery pack. The sensor assembly includes a temperature sensor, the signal output end of the sensor assembly is connected to the controller; the signal output end of the controller is connected to the electric push rod 23. The controller and the electric push rod 23 are powered by a lithium battery pack. When the temperature sensor detects that the temperature exceeds a set threshold, the controller controls the electric push rod 23 to move the support plate 2 up, thereby opening the first heat dissipation hole 11 . When the temperature sensor detects that the temperature is lower than the set threshold, the controller controls the electric push rod 23 to move, so that the support plate 2 is lowered, thereby closing the first heat dissipation hole 11. In actual use, when the power supply is discharged outdoors, it is generally not necessary to open the first heat dissipation hole 11, generally only when charging the lithium battery pack, because the charge generates a lot of heat inside the power supply, so the first heat dissipation needs to be turned on The hole 11 performs heat dissipation treatment.

The side wall of the box 1 is provided with a charging port 7 and a discharging port 8, a charging socket 71 is installed in the charging port 7, and a discharging socket 81 is installed in the discharging port 8. In order to prevent rain water from wetting the charging socket 71 and the discharging socket 81, on the side wall of the cabinet 1 are installed opening and closing doors that can open and close the charging port 71 and the discharging port 81, respectively. The opening and closing door is preferably hingedly connected to the cabinet Connected. In order to improve the convenience of use, the cabinet 1 is also provided with an installation port for installing a power display screen.

In order to further enhance the effect of heat dissipation, second heat dissipation holes 21 are distributedly installed on the support plate 2, and a protrusion 22 supporting the power supply body 9 is installed on the upper surface of the support plate 2. The protrusions 22 are preferably several sets of wave protrusions, and are staggered with the second heat dissipation holes 21

During installation, the cover 5 is opened, the power supply body 9 is placed on the support plate 2, and then the positioning plate 3 is placed horizontally inside the cabinet 1, and the clamping plate 44 below the positioning plate 3 fixes the periphery of the power supply body 9. Then, the cover 5 is closed, and the pressing plate 63 on the cover 5 presses the positioning plate 3 tightly. When the supporting plate 2 moves upward, the positioning plate 3, the pressing plate 63, and the power supply body 9 move upward as a whole. The power supply body 9 can still be positioned and fixed by the clamping plate 44. When the supporting plate 2 moves downward, the second spring 6 As a result, the positioning plate 3 can move down with the power body 9 as a whole, so that the power body 9 can still be positioned and fixed.

This embodiment can effectively prevent dust, water, etc. from entering the power supply. In addition, by providing the clamping plate 44 and the positioning plate 3 around the power supply body 9, the power supply body 9 can be fixed in the middle of the cabinet 1, so that it is not easily shaken during transportation, and meets the needs of the power supply for outdoor work.
