At this time, the dovetail clamping block can be moved inside the dovetail groove to make it face the position of the wire. Then, the connecting wires are passed through the two groups of positioning frames and the clamping strips.

This heat dissipation method enables the device to cope with sudden high temperature conditions or to enhance heat dissipation in specific working stages, thereby increasing the adaptability of the device under different working conditions.

[0039] A limit block 42 is fixedly installed on the screw rod 41, and a positioning frame 51 is symmetrically arranged on one side of the electric energy meter box 11. Second slide grooves 52 are symmetrically opened inside the two positioning frames 51, and springs 53 are fixedly installed in the inner walls of the two groups of second slide grooves 52. A clamping strip 54 is arranged on one side of the two positioning frames 51, and second sliders 55 are fixedly installed at both ends of the two clamping strips 54.

The box 11 is fixedly connected, and a slide column 61 is symmetrically fixedly installed on the lower end of the positioning frame 51 located above, and the positioning frame 51 located below is slidably installed on the slide column 61. A guide frame 62 is fixedly installed on the side wall of the electric energy metering box 11, and the guide frame 62 is fixedly connected to the two slide columns 61. A first guide column 63 and a second guide column 64 are arranged inside the guide frame 62. The first guide column 63 and the second guide column 64 are staggered. A limit strip 65 is fixedly installed on the two slide columns 61, and the limit strip 65 is located between the two positioning frames 51. When in use, the electrical components are first installed inside the mounting frame 35, and the connecting wires are passed through the wire groove 28 and the accommodating groove 19, and then the two clamping strips 54 are pulled outward, and the two clamping strips 54 will drive the two groups of second sliders 55 to move between the two groups of first The two slide grooves 52 slide outward, and the two sets of springs 53 will be stretched accordingly. At this time, the dovetail clamp block 57 can be moved inside the dovetail groove 56 to make it face the position of the wire, and then the connecting wire is passed through the two sets of positioning frames 51 and the clamping strip 54. After the clamping strip 54 is loosened, the dovetail clamp block 57 located above will fix the wire, and the cleaning block 58 located below will fix the wire, and then it will pass between the first guide column 63 and the second guide column 64. Then, the screw rod 41 can be rotated in the connecting frame 39, and the screw rod 41 will drive the limit block 42 to rotate, thereby releasing the limit on the positioning frame 51 located below. At this time, the positioning frame 51 located below can be moved downward until it contacts the guide frame 62, and the wire can be moved along the wire under the movement of the positioning frame 51 The straight processing prevents the wire from being in a twisted state, which helps to reduce the stress inside the wire and extend the service life of the wire.

After the wire is fixed, the device is placed at a designated location and the wire is connected to the power supply for use. When it is sunny outdoors, the mounting frame 35 can be kept at the bottom of the electric energy meter box 11.

When it is in the rainy season, the connecting frame 39 can be moved upward, and the movement of the connecting frame 39 will drive the two inner rods 38 to move upward inside the two first inner grooves 13. When the limit block 42 moves to the top of the limit bar 65, the screw 41 can be rotated on the connecting frame 39, and the screw 41 drives the limit block 42 to rotate. The third heat dissipation port 36 on the mounting frame 35 will be located between the two groups of first heat dissipation ports 14 and second heat dissipation ports 15, and will fit with the inner wall of the electric energy meter box 11. At this time, the air flow channel will be closed, thereby achieving the effect of rain protection. If the heat dissipation effect needs to be enhanced, the connecting frame 39 can be moved upward to the top. At this time, the screw 41 is rotated to make the limit block 42 rest on the positioning frame 51 located above for limiting. At this time, the mounting frame 35 will be in the electric energy meter. The inside of the box 11 moves upward, and at this time the third heat dissipation port 36 will overlap with the first heat dissipation port 14, and the air flow channel will be opened again for heat dissipation. At this time, the mounting frame 35 and the electrical components mounted thereon will be suspended, increasing the heat dissipation area and expanding the heat dissipation space, thereby enhancing the heat dissipation effect of the equipment. The equipment has an excellent ability to adapt to the environment and can flexibly adjust the heat dissipation and protection state according to different weather conditions (on sunny days, the air flow channel is opened, and the natural wind circulation effectively dissipates heat, maintains the normal working temperature of the electrical components, prolongs their service life and improves their performance; in rainy seasons, the channel is closed to prevent rainwater from intruding, prevent electrical components from being damp and short-circuited, ensure the normal operation of the equipment in bad weather, and reduce the risk of failure; in addition, the heat dissipation effect can be enhanced as needed, and the equipment can be moved upward to make the electrical components suspended, increase the heat dissipation area and space, improve the heat dissipation efficiency, and meet high load or high temperature requirements). This adaptive mechanism reduces failures caused by overheating or humidity, reduces maintenance costs, protects electrical components, ensures the stable operation of the entire system, and improves the reliability and stability of the equipment.

[0040] Working principle:

[0041] The first step is to install the electrical components inside the mounting frame 35, pass the connecting wires through the wire groove 28 and the receiving groove 19, and then pull the two clamping strips 54 outward, the two clamping strips 54 will drive the two sets of second sliders 55 to slide outward inside the two sets of second slide grooves 52, and the two sets of springs 53 will be stretched. At this time, the dovetail clamp block 57 can be moved inside the dovetail groove 56 to make it face the position of the wires, and then pass the connecting wires through the two sets of positioning frames 51 and the clamping strips 54. After loosening the clamping strips 54, the dovetail clamp block 57 located above will fix the wires, and the cleaning block 58 located below will fix the wires, and then pass it between the first guide column 63 and the second guide column 64, and then it can be placed in the connecting frame 39. The screw rod 41 is rotated, and the screw rod 41 will drive the limit block 42 to rotate, thereby releasing the limit on the positioning frame 51 located below. At this time, the positioning frame 51 located below can be moved downward until it contacts the guide frame 62. The wire can be straightened under the movement of the positioning frame 51, so that it will not be in a twisted state, which helps to reduce the stress inside the wire and extend the service life of the wire. At the same time, it ensures the stability of power transmission, reduces energy consumption and the risk of line failure. In addition, the cleaning block 58 can also clean the surface of the wire synchronously under the movement of the positioning frame 51, which helps to remove dirt, impurities or oxide layers on the surface of the wire, improve the conductivity of the wire, and ensure the efficiency and quality of power transmission.

[0042] In the second step, after the wires are fixed, the device is placed at a designated location and the wires are connected to a power source for use. When it is sunny outdoors, the mounting bracket 35 can be kept at the bottom of the electric energy meter box 11. At this time, the two third heat dissipation ports 36 on the mounting bracket 35 will overlap with the two second heat dissipation ports 15 on the electric energy meter box 11. At this time, the external air forms an air flow channel with the second heat dissipation ports 15 and the third heat dissipation ports 36, and the external air can be circulated to take away the heat generated by the operation of the electrical components inside the electric energy meter box 11, thereby achieving a heat dissipation effect. When it is in the rainy season, the connecting bracket 39 can be moved upwards to connect the connecting bracket 39. The movement of the frame 39 will drive the two inner rods 38 to move upward inside the two first inner grooves 13. When the limit block 42 moves to above the limit strip 65, the screw 41 can be rotated on the connecting frame 39, and the screw 41 drives the limit block 42 to rotate and rest on the upper end of the limit strip 65, thereby limiting the connecting frame 39. At this time, the third heat dissipation port 36 on the mounting frame 35 will be between the two groups of first heat dissipation ports 14 and second heat dissipation ports 15, and fit with the inner wall of the electric energy metering box 11. At this time, the air flow channel will be closed, thereby achieving the effect of rain protection. If the heat dissipation effect needs to be enhanced, the connecting frame 39 can be moved upward at this time. Move to the top, at this time, rotate the screw rod 41, so that the limit block 42 is placed on the positioning frame 51 located above for limiting, and at this time the mounting frame 35 will move up inside the electric energy meter box 11, and at this time the third heat dissipation port 36 will overlap with the first heat dissipation port 14, and the air flow channel will be opened again for heat dissipation. At this time, the mounting frame 35 and the electrical components installed thereon will be in a suspended state, which increases the heat dissipation area and expands the heat dissipation space, thereby enhancing the heat dissipation effect of the equipment. The equipment has an excellent ability to adapt to the environment and can flexibly adjust the heat dissipation and protection states according to different weather conditions (on sunny days, the air flow channel is opened). , effectively dissipate heat through natural wind circulation, maintain the normal working temperature of electrical components, extend their service life and improve performance; in rainy seasons, closing the channel can prevent rainwater from intruding, avoid short circuit of electrical components due to moisture, ensure normal operation of equipment in bad weather, and reduce the risk of failure; in addition, the heat dissipation effect can be enhanced as needed, the equipment can be moved up to make the electrical components suspended, increase the heat dissipation area and space, improve the heat dissipation efficiency, and meet high load or high temperature requirements). This adaptive mechanism reduces failures caused by overheating or moisture, reduces maintenance costs, protects electrical components, ensures stable operation of the entire system, and improves the reliability and stability of the equipment;

[0043] In the third step, when the equipment needs to dissipate heat quickly, the screw 41 is first screwed on the connecting frame 39 until the limit block 42 is rotated to the state facing the electric energy meter box 11. At this time, the connecting frame 39 can be pulled up and down, and the movement of the connecting frame 39 will drive the mounting frame 35 to move upward in the fixed box 24. At this time, the mounting frame 35 will drive the fixed box 24 to move upward, and the sealing plate 34 will drive the inner plate 31 to move upward inside the second inner groove 25. When the mounting frame 35 moves upward, the space at the bottom of the electric energy meter box 11 will be opened, and a large amount of air will flow in from the outside. (similar to the state of an air pump), the air will enter the space where the electronic components are located through the fourth heat dissipation port 37 and mix with the hot air. When the mounting frame 35 moves downward, the gas will be discharged through the third heat dissipation port 36 and the second heat dissipation port 15, thereby achieving rapid ventilation in a short period of time, so that the device can actively operate to meet the heat dissipation needs of the device, rather than relying entirely on passive heat dissipation or conventional heat dissipation mechanisms. This heat dissipation method enables the device to cope with sudden high temperature conditions or to enhance heat dissipation in specific working stages, increasing the adaptability of the device under different working conditions;

[0044] The fourth step, when it is necessary to repair or replace the electronic components installed on the mounting frame 35, the closing plate 34 can be moved upward, and the movement of the closing plate 34 will drive the inner plate 31 to move inside the second inner groove 25. When the inner plate 31 moves to the uppermost end inside the second inner groove 25, the first slider 33 can be moved to either end inside the first slide groove 32, and the first slider 33 can be inserted into any slot 26 to complete the snap connection. At this time, the closing plate 34 will remain retracted into the fixed box 24, thereby providing an operable space, greatly improving the convenience and efficiency of maintenance.
