[0002] Municipal roads refer to urban roads, which are connected to various areas of the city and are used for transportation and pedestrians within the city. They are convenient for residents' lives, work, cultural and entertainment activities, and are connected to roads outside the city to carry external traffic. The roads contain tunnels and bridges. In order to prevent vehicles from being too high and hitting bridges and tunnels, causing damage to bridges and tunnels, height limit poles are usually set at the entrances of bridges and tunnels to protect bridges and tunnels.

[0003] A Chinese patent with publication number CN212956241U provides a multifunctional height limit pole for roads and bridges, which solves the problem that the top gear bar of the existing height limit pole is fixedly set, so that after a vehicle hits the height limit pole, the vehicle is seriously damaged and the height limit pole is knocked down, causing casualties. By arranging a rubber plate and a bearing cylinder, the rubber plate, the mounting plate and the height limit plate are flipped on the outside of the top column following the bearing cylinder after the collision, so that the vehicle will not directly hit hard, avoiding knocking down the height limit pole or serious damage to the vehicle causing casualties. The water in the water tank cavity can be transferred to the inner cavity of the delivery pipe through a water pump and finally sprayed out through a spray head, which is conducive to dust reduction, especially in dry weather when vehicles pass by with flying dust, seriously affecting the environment.

[0004] In addition to the above-mentioned advantages, this utility model patent still has some shortcomings: the municipal road height limit pole has a fixed height and cannot be adjusted, which results in the inability to quickly and temporarily adjust the height limit when some special vehicles need to pass urgently, restricting the passage of emergency vehicles and delaying the work progress of emergency vehicles.

DETAILED DESCRIPTION

[0022] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0023] See also Figure 1-3 , the utility model provides a technical solution:

[0025] In this embodiment, please refer to Figure 5 The photovoltaic panel 4 includes a mounting plate 41, the top of the mounting plate 41 is electrically connected to a number of N-type silicon layers 42, the top of the N-type silicon layer 42 is electrically connected to a generator 43, the top of the generator 43 is electrically connected to a P-type silicon layer 44, and a top cover 45 is fixedly connected to the outer side of the top of the mounting plate 41.

[0026] In this embodiment, please refer to Figure 2 , Figure 4 The positioning member 6 includes a sleeve 61, one end of the inner cavity of the sleeve 61 is fixedly connected to a spring 62, and the other end of the inner cavity of the sleeve 61 is movably connected to a resistance ball 63, which is beneficial for the resistance ball 63 to move backward under pressure when the movable column 22 moves up and down, and is squeezed out of the inner cavity of the positioning hole 24, so that the spring 62 is squeezed and deformed. When the position of the movable column 22 is adjusted and the resistance ball 63 is aligned with the positioning hole 24, the spring 62 loses pressure and returns to its original state, and re-enters the inner cavity of the positioning hole 24, so that the adjusted height of the movable column 22 remains stable and will not move easily, thereby keeping the position of the height limit rod stable.

[0027] In this embodiment, please refer to Figure 3 The outer side of the lifting shaft 54 ​​is provided with a spiral pattern, and the inner wall of the positioning sleeve 53 is provided with a spiral groove adapted to the spiral pattern on the outer side of the lifting shaft 54, which is conducive to the lifting shaft 54 ​​to move upward along the inner wall of the positioning sleeve 53 when it rotates clockwise, and to move downward along the inner wall of the positioning sleeve 53 when the lifting shaft 54 ​​rotates counterclockwise.

[0028] In this embodiment, please refer to Figure 5The bottom of the mounting plate 41 is electrically connected to four conductors 47, and the bottom of the conductor 47 is electrically connected to a battery 46. The battery 46 is electrically connected to the servo motor 51, the warning strip 7, and the camera 8 through wires, which is beneficial for the photovoltaic panel 4 to convert light energy into electrical energy, store electricity through the battery 46, and conduct the current to the equipment that needs electricity through the wires to provide electrical energy.

[0029] In this embodiment, please refer to Figure 2 , Figure 4 The outer side of the resistance ball 63 is adapted to the inner cavity of the positioning hole 24, and the diameter of the resistance ball 63 is slightly larger than the aperture of the positioning hole 24, which is conducive to the front end of the resistance ball 63 entering the inner cavity of the positioning hole 24, so that the position of the movable column 22 remains relatively stable, and at the same time avoids the resistance ball 63 being unable to escape from the inner cavity of the positioning hole 24 when the movable column 22 is driven to move, resulting in failure of adjustment of the height limit rod.

[0030] Working principle of this utility model:

[0031] Step 1, in the utility model, a height adjustment component 5 is provided, and the height adjustment component 5 includes a servo motor 51. The servo motor 51 provides power to control the rotation of the telescopic rod 52, and the rotation of the telescopic rod 52 drives the lifting shaft 54 ​​to rotate along the inner wall of the positioning sleeve 53. Since the outer side of the lifting shaft 54 ​​is provided with a spiral pattern, the inner wall of the positioning sleeve 53 is provided with a spiral groove adapted thereto, the lifting shaft 54 ​​can be controlled to rotate clockwise to make it move upward along the inner wall of the positioning sleeve 53, and the length of the telescopic rod 52 is elongated, and the movable column 22 is pushed upward by the lifting shaft 54 ​​to move upward along the inner cavity of the fixed column 21, and the support column 23 is moved upward by the movable column 22, so that the height of the cross bar 3 is increased, and a vehicle with a higher height can pass through its bottom. According to the above principle, the cross bar 3 can be lowered at a high speed by controlling the lifting shaft 54 ​​to rotate counterclockwise, so that the height of the vehicle is limited;

[0032] Step 2. In the utility model, a photovoltaic panel 4 is provided, and the photovoltaic panel 4 includes an N-type silicon layer 42 and a P-type silicon layer 44. A PN junction is formed between the N-type silicon layer 42 and the P-type silicon layer 44, and electrons can move. A positive charge is generated on the P-type silicon layer 44, and a negative charge is generated on the N-type silicon layer 42. These electrons are allowed to move freely by sunlight exposure, but due to the PN junction, they can only move in one direction. These electrons are absorbed by the generator 43, and converted into electric current by the generator 43, and enter the battery 46 through the conductor 47. The battery 46 collects and stores electrical energy, and the battery 46 conducts the current to the servo motor 51, the warning strip 7, and the camera 8 through the wire to provide them with electric energy for operation.
