The adsorption component is in sliding fit with the outer wall of the lamp post main body 2, thereby taking away the heat generated on the surface.
[0031] The wire - regulating component includes a wire - fixing frame 35 fixedly installed inside the interface box 11. Arc - shaped openings 36 are equidistantly arranged inside the wire - fixing frame 35 in the horizontal direction.

[0032] Refer to the attached instruction manual Figure 7 It can be seen that structures such as cables or communication optical fibers can be clamped inside the corresponding arc - shaped openings 36. Then, the rubber clamping seat 37 is passed through the outside of the two fixed bolts 38, and the rubber clamping seat 37 is positioned with the nut 39, thereby fixing the line. Thus, it can ensure that the cables used inside the lamp post main body 2 can be neatly arranged.
[0033] The intelligent device includes an LED signal screen 8 arranged above the outer side of the lamp post main body 2. An IP sound column 7 is arranged above the LED signal screen 8 on the outer side of the lamp post main body 2. An environmental monitoring device 6 is arranged above the lamp post main body 2.

The side plate 9 is fixedly clamped inside the sliding seat 33.
[0036] Refer to the attached instruction manual Figure 6 It can be seen that the sliding seat 33 can move horizontally outside the support rod 12, and thus can be finely adjusted during use, and then positioned by the pin rod 34.
[0037] The ventilation component includes a ventilation fan 10 embedded inside the side plate 9, and a ventilation pipe 15 is connected and installed below the inside of the ventilation fan 10.
[0038] Refer to the attached instruction manual Figure 1 、 Figure 2and Figure 3 It can be seen that the ventilation fan 10 can transport the external air flow into the lamp post main body 2, thereby accelerating the flow of the internal air flow.
[0039] The dispersion component includes a ring 43 slidably mounted on the outside of the guide pipe 16. A ventilation box 41 is connected to the outside of the ring 43 through a connecting pipe 42 provided. A clamping seat 40 is sleeved outside the ventilation box 41. The clamping seat 40 is made of metal material. A hose 14 is connected and installed above the inside of the connecting pipe 42. The hose 14 is connected to the inside of the guide pipe 16. An electric control valve 17 is provided outside the ventilation pipe 15;
[0040] Refer to the attached instruction manual Figure 3 and Figure 8 It can be seen that the ring 43 can, by virtue of the connection of the connecting pipe 42, cause the clamping seat 40 to move at the corresponding position. The electric control valve 17 can control the switch according to the usage requirements, so that the air flow is transported to the lower part inside the lamp post main body 2. The hose 14 is a sliding and telescopic pipeline for use.
[0041] The reciprocating component includes a lead screw 24 rotatably mounted inside a positioning frame 18. A fixed box 23 is fixedly provided at the upper end of the positioning frame 18. A clamping plate 22 is clamped at the upper end of the fixed box 23. A motor 21 is provided inside the fixed box 23. The lead screw 24 is in threaded cooperation with a support seat 19. One end of the support seat 19 away from the lead screw 24 is slidably engaged with the edge of the positioning frame 18;
[0042] Refer to the attached instruction manual Figure 4 It can be seen that the clamping plate 22 is a clamping structure and is clamped and connected to the fixed box 23. After the motor 21 is started, it can drive the lead screw 24 to rotate. The support seat 19 in threaded cooperation with the lead screw 24 can move up and down inside the positioning frame 18 under the sliding and positioning of the positioning frame 18, thereby driving the external structure to reciprocate up and down.
[0043] The connecting component includes a clamping post 28 fixedly installed inside the support seat 19. Two abutting posts 29 are fixedly sleeved at both ends of the outside of the clamping post 28. The two abutting posts 29 are fixedly connected to a water storage tank 25. The lower end of the support seat 19 is made of magnetic plate material and is magnetically attracted to the clamping seat 40. A filter plate 27 is provided above the inside of the water storage tank 25;
[0044] Refer to the instruction manual Figure 4 and Figure 5 It can be seen that the clamping post 28 and the abutting posts 29 can ensure that the water storage tank 25 can stably move up and down with the support seat 19. Since most of the lamp post main bodies 2 in the prior art are made of aluminum alloy materials, the support seat 19 made of magnetic plate material and the clamping seat 40 made of metal material can be internally and externally fitted and moved under the condition of strong magnetic attraction;
[0045] The filter plate 27 can filter out the impurities entering the water storage tank 25.
[0046] The suction and attachment assembly includes a guiding box 20 fixedly arranged below the outer side of the water storage tank 25. The bottom inside the water storage tank 25 is communicated with the inside of the guiding box 20 through a plurality of connected circulation pipes 31. Solenoid valves are arranged inside the plurality of circulation pipes 31. At both ends inside the guiding box 20 and near the lower part, there are clamping rods 26. A cotton roller 30 is rotatably arranged between the two clamping rods 26. The cotton roller 30 is in rolling contact with the outer walls on both sides of the lamp post main body 2. One end inside the guiding box 20 is communicated and installed with an outflow pipe 32;
[0047] Refer to the attached instruction manual Figure 4 and Figure 5 It can be seen that under the connection of the plurality of circulation pipes 31, the drainage of the water inside the water storage tank 25 can be controlled. The discharged water can flow from the ends of the plurality of circulation pipes 31 to the surface of the cotton roller 30. Thus, when the cotton roller 30 rolls, the water can be rolled and pressed on the outer wall of the lamp post main body 2, and then the heat can be taken away. The setting of the outflow pipe 32 is to facilitate the drainage of the overflow water in the water storage tank 25 in the case of abundant rain in the later period. A control valve can be set at the outflow pipe 32.
[0048] Working principle: When the lamp post main body 2 is in use, the heat generated intensively below the inside can be driven reciprocally by the reciprocating assembly, causing the support seat 19 to drive the guiding box 20 and the water storage tank 25 to move inside the positioning frame 18. During the up and down movement, the support seat 19 made of magnetic plate material will slide on the outer wall of the lamp post main body 2. At the same time, the clamping seat 40 made of metal material will move synchronously with the support seat 19 by magnetic attraction, and then drive the ventilation box 41 inside to move up and down inside the lamp post main body 2. Then, start the ventilation fan 10 inside the side plate 9 to ventilate the air inside the lamp post main body 2. After the air flow enters the guiding pipe 16, it is conveyed to the inside of the connecting pipe 42 through the hose 14, so that the ventilation box 41 can distribute the air flow everywhere up and down inside the lamp post main body 2 during the movement, and then ventilate the heat generated at different positions on one side of the wire fixing assembly, reduce the internal heat, and accelerate the air flow. The stored water inside the water storage tank 25 can be supplied for the use of the guiding box 20. The solenoid valves inside the circulation pipes 31 can control the water flow down. While dissipating heat and ventilating, the solenoid valves control the water to flow to the surface of the cotton roller 30 inside the guiding box 20. During the up and down movement, the water can be suction-attached to the inside of the lamp post main body 2 by means of rolling contact, thereby reducing the heat generated on the outer wall. The two methods work together inside and outside to fully dissipate the heat of the connection line at the lower end of the lamp post main body 2, greatly ensuring the use of the lamp post main body 2.
[0049] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, various changes and improvements will occur to the present invention, and all these changes and improvements fall within the scope of the present invention claimed.
