Description

Technical Field

[0001] This utility model relates to the field of road traffic technology, specifically a traffic signal for road traffic control. Background Technology

[0002] Signals are trackside infrastructure for railways and urban rail transit. In railway signaling systems, which primarily use ground signals, drivers must operate according to the signal displays. In urban rail transit systems, which primarily use onboard signals, there are generally no signals on the main line sections. Ground signals are only installed in turnout sections for shunting operations.

[0003] According to announcement number CN221103821U, a road traffic control signal controller relates to the field of road traffic technology. The signal controller includes a signal controller sealing door fixedly installed on its front, and anti-collision components fixedly connected to both the left and right sides. Heat dissipation components are fixedly connected to the inner cavities of both anti-collision components. This road traffic control signal controller, through the action of a waterproof layer and a silicone layer, prevents the internal components from being corroded by the external environment during long-term use. The silicone layer also adds cushioning between the outer and inner shells, reducing impact force. The action of rubber blocks and buffer springs increases the cushioning force inside the inner shell. Simultaneously, the action of shock absorber one ensures that the force generated by the buffer spring during cushioning does not affect the signal controller. The action of shock absorber two and U-shaped rubber blocks achieves cushioning and shock absorption at the four corners of the signal controller, thus providing better protection for the signal controller.

[0004] The aforementioned device is equipped with anti-collision components to provide better protection for the signal. According to the instruction manual and attached drawings, there is no drainage device at the bottom of the signal. If the signal is installed directly on the ground or a low base, rainwater will flow back into the signal from the gaps at the bottom, affecting the operation of the electronic components inside the signal. Utility Model Content

[0005] The purpose of this utility model is to provide a road traffic control signal that solves the problem that if a traffic signal is installed directly on the ground or a low base and there is no drainage device at the bottom, rainwater will flow back into the signal through the gaps at the bottom, affecting the use of the electronic components inside the signal.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a traffic signal controller for road traffic control, comprising a signal controller body, a waterproof base fixedly installed at the bottom of the signal controller body, a drainage base fixedly installed at one end of the waterproof base, water inlet mesh plates symmetrically fixedly installed on the outer periphery of the waterproof base, a water outlet pipe fixedly installed at one end of the drainage base, a drainage pipe fixedly installed at one end of the drainage base, a rotating plate rotatably connected to one end of both the water outlet pipe and the drainage pipe, and the rotating plate opens and closes in one direction, a piston plate slidably connected inside the drainage base, a connecting rod slidably connected to the top of the drainage base, and the connecting rod is fixedly installed with the piston plate, the piston plate being located in the middle of the water outlet pipe and the drainage pipe.

[0007] As a further embodiment of this utility model: a mounting plate is fixedly installed at one end of the signal body, a rotating disk is rotatably connected to one end of the mounting plate, and a connecting disk is provided at one end of the rotating disk. A circular groove is opened at one end of the connecting disk, and a connecting shaft is fixedly installed at one end of the connecting rod, and the connecting shaft is adapted to the circular groove.

[0008] As a further embodiment of this utility model: a rotating motor is fixedly mounted on one end of the mounting plate, and the output shaft of the rotating motor is fixedly mounted to the rotating disk.

[0009] As a further embodiment of this utility model: an mounting block is fixedly installed at one end of the connecting disk, a connecting block is fixedly installed at one end of the rotating disk, the mounting block and the connecting block are slidably connected, and a threaded rod is rotatably connected inside the connecting block, and the threaded rod is threadedly connected to the mounting block.

[0010] As a further improvement of this utility model: a support rod is fixedly installed at the bottom of the waterproof base, and the support rod is symmetrically fixedly installed at the bottom of the waterproof base.

[0011] As a further improvement of this utility model: heat dissipation components are symmetrically arranged at both ends of the signal body, anti-collision components are arranged around the signal body, a rain shelter is fixedly installed on the top of the signal body, and a sealed door is provided at one end of the signal body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The signal body of this utility model is raised and installed by a support rod to avoid direct contact with the ground and reduce the probability of water immersion in the base. The water inlet mesh plate on the outer periphery of the waterproof base can filter mud, sand, fallen leaves and other debris to prevent blockage of the drainage channel. At the same time, it only allows water to seep in in an orderly manner, preventing debris from entering the interior with the water and causing malfunctions. The dual pre-treatment design reduces the risk of water backflow from the source and lays the foundation for subsequent drainage, initially ensuring that the bottom of the signal is dry.

[0014] This invention uses a rotating motor to drive a rotating disk and a connecting disk in conjunction. A circular groove and a connecting shaft drive a piston plate to move up and down reciprocally. When the piston plate moves upward, it creates negative pressure to draw in water, and when it moves downward, it generates high pressure to discharge the water. With the help of a one-way rotating plate to prevent backflow, it achieves a cycle of water intake and discharge, which can quickly drain water that has seeped into the waterproof base, prevent water from accumulating and flowing back through the gaps, and protect the internal electronic components.

[0024] Reference Figures 1 to 6 In this embodiment of the utility model, a traffic signal controller for road traffic control includes a signal controller body 1. A waterproof base 2 is fixedly installed at the bottom of the signal controller body 1. A drainage base 4 is fixedly installed at one end of the waterproof base 2. Water inlet mesh plates 3 are symmetrically fixedly installed on the outer periphery of the waterproof base 2. A water outlet pipe 23 and a drainage pipe 5 are fixedly installed at one end of the drainage base 4. A rotating plate 6 is rotatably connected to one end of both the water outlet pipe 23 and the drainage pipe 5, and the rotating plate 6 opens and closes in one direction. A piston plate 7 is slidably connected inside the drainage base 4, and a piston plate 7 is slidably connected to the top of the drainage base 4. There is a connecting rod 11, and the connecting rod 11 is fixedly installed with the piston plate 7. The piston plate 7 is located in the middle of the water outlet pipe 23 and the drain pipe 5. One end of the signal body 1 is fixedly installed with a mounting plate 8. One end of the mounting plate 8 is rotatably connected to a rotating disk 9, and one end of the rotating disk 9 is provided with a connecting disk 10. One end of the connecting disk 10 has a circular groove 12. One end of the connecting rod 11 is fixedly installed with a connecting shaft 13, and the connecting shaft 13 is adapted to the circular groove 12. One end of the mounting plate 8 is fixedly installed with a rotating motor 14, and the output shaft of one end of the rotating motor 14 is fixedly installed with the rotating disk 9.

[0025] The above-mentioned scheme is adopted as follows: The signal body 1 is based on the prior art in the referenced document and is not described in detail in this application. The waterproof base 2 welded to the bottom of the signal body 1 is made of stainless steel, which has excellent corrosion resistance and the inner wall is waterproof and sealed. The drainage base 4 welded to one end is made of the same material as the waterproof base 2. The water inlet mesh plate 3 symmetrically welded to the outer periphery of the waterproof base 2 is also made of stainless steel, with uniform mesh and smooth edges, which can filter impurities and prevent clogging. The water outlet pipe 23 and the drain pipe 5 welded to one end of the drainage base 4 are both made of PVC, which is lightweight and chemically resistant. The rotating plate 6, which is connected to one end by a hinge, is made of engineering plastic and has a waterproof sealing strip on the surface. It can only be opened and closed in one direction outward. The drainage base 4 is internally slidably connected Piston plate 7 is made of rubber-coated metal core with sealing rings at the edges to ensure no leakage during sliding. Connecting rod 11 welded to the top is made of stainless steel, which is rigid and not easily bent, and is fixed to piston plate 7. Mounting plate 8 welded to one end of signal body 1 is made of alloy material with high flatness and is used to fix components. Rotating disk 9, which is connected to one end by bearing, is made of alloy material. Connecting disk 10 welded to one end is made of the same material as rotating disk 9. The inner wall of the circular groove 12 opened at one end of connecting disk 10 is smooth to accommodate the movement of connecting shaft 13. Connecting shaft 13 welded to one end of connecting rod 11 is made of stainless steel and fits precisely with circular groove 12. Rotating motor 14, which is bolted to one end of mounting plate 8, is a waterproof motor suitable for outdoor environments. The output shaft is welded to rotating disk 9.

[0026] Reference Figures 1 to 6 One end of the connecting plate 10 is fixedly installed with an installation block 16, and one end of the rotating plate 9 is fixedly installed with a connecting block 15. The installation block 16 and the connecting block 15 are slidably connected. The connecting block 15 is rotatably connected with a threaded rod 17, and the threaded rod 17 is threadedly connected to the installation block 16. The bottom end of the waterproof base 2 is fixedly installed with a support rod 18, and the support rod 18 is symmetrically fixedly installed at the bottom end of the waterproof base 2.

[0027] The above-mentioned scheme is adopted as follows: the mounting block 16, which is welded and fixed to one end of the connecting plate 10, is made of wear-resistant alloy material with a smooth surface to reduce sliding resistance. The connecting block 15, which is welded and fixed to one end of the rotating plate 9, is made of the same material as the mounting block 16 to ensure sliding compatibility. The mounting block 16 and the connecting block 15 are slidably connected and fit tightly. The threaded rod 17, which is rotated and connected to the connecting block 15 through a bearing, is made of high-strength stainless steel with a chrome-plated surface for rust prevention and high thread precision, precisely meshing with the threaded hole opened inside the mounting block 16. The support rod 18, which is welded and fixed to the bottom of the waterproof base 2, is made of stainless steel with uniform wall thickness and high rigidity, and is symmetrically distributed at the bottom of the waterproof base 2 to provide stable support. The advantage of this structure is that when the threaded rod 17 is rotated, the mounting block 16 is driven to slide along the connecting block 15 through thread engagement, thereby adjusting the connection plate 10 and the rotating plate. The spacing between 9 changes the radius of the movement trajectory of the connecting shaft 13 within the circular groove 12, ultimately achieving stroke adjustment of the piston plate 7's reciprocating motion. Increasing the stroke increases the single drainage volume of the drainage base 4, while decreasing the stroke accelerates the drainage frequency, adapting to drainage needs under different water accumulation conditions and enhancing equipment flexibility. The sliding fit between the mounting block 16 and the connecting block 15 provides guidance for the movement of the connecting plate 10, preventing it from shifting and ensuring that the connecting plate 10 maintains stable transmission during the adjustment of the threaded rod 17. This avoids jamming of the connecting rod 11 and piston plate 7 due to positional shift. The symmetrically arranged support rods 18 provide stable support for the waterproof base 2 and the signal body 1, raising the bottom height of the waterproof base 2 and reducing the risk of ground water directly immersing the base. At the same time, it enhances the overall structure's resistance to tipping in outdoor environments.

[0028] Reference Figures 1 to 6 The signal body 1 is symmetrically provided with heat dissipation components 22 at both ends, and anti-collision components 20 are provided around the signal body 1. A rain shelter 21 is fixedly installed on the top of the signal body 1, and a sealing door 19 is provided at one end of the signal body 1.

[0029] The above-mentioned solution includes: heat dissipation component 22, anti-collision component 20, rain shelter 21, and sealing door 19, all of which are prior art referenced in the prior art documents and are not described in detail in this application. Heat dissipation component 22 includes a fixing frame, a blower, and a heat dissipation plate, etc. Heat dissipation component 22 can dissipate heat from the temporal part of signal body 1. Anti-collision component 20 includes a buffer spring, shock absorber one, and shock absorber two, etc. Anti-collision component 20 can buffer and reduce shock at the four corners of signal body 1, thereby providing better protection for signal body 1.

[0030] The working principle of this utility model is as follows: When installing the signal body 1, the signal body 1 is raised by the support rods 18 symmetrically fixed at the bottom of the waterproof base 2, avoiding direct contact between the signal body 1 and the ground, reducing the probability of ground water directly soaking the base of the signal body 1. At the same time, the water inlet mesh plate 3 on the outer periphery of the waterproof base 2 can filter debris in the rainwater, such as mud, sand, fallen leaves, etc., to prevent debris from entering and causing blockage. When the water accumulation increases during rainy days, some of the accumulated water will seep into the interior through the water inlet mesh plate 3 of the waterproof base 2. At this time, the rotation of one end of the mounting plate 8 is activated. The motor 14 drives the rotating disk 9 to rotate via its output shaft. The connecting block 15 at one end of the rotating disk 9 rotates accordingly. The connecting block 15 is connected to the connecting disk 10 via a mounting block 16. The mounting block 16 and the connecting block 15 are slidably connected, and the threaded rod 17 can adjust the distance between them, thereby adjusting the rotation radius of the connecting disk 10. When the connecting disk 10 rotates, its circular groove 12 at one end matches the connecting shaft 13 at the top of the connecting rod 11. The inner wall of the circular groove 12 generates a periodic up-and-down thrust on the connecting shaft 13, driving the connecting rod... 11 slides up and down along the top of the drainage base 4. The connecting rod 11 is fixedly connected to the piston plate 7 inside the drainage base 4. Therefore, the piston plate 7 will move up and down synchronously with the connecting rod 11. When the piston plate 7 moves upward, the volume of the space below the piston plate 7 inside the drainage base 4 increases and the air pressure decreases, forming a negative pressure. At this time, the one-way rotating plate 6 at one end of the water outlet pipe 23 is attracted and opened by the negative pressure, while the rotating plate 6 at one end of the drainage pipe 5 remains closed due to its one-way opening and closing characteristic. The accumulated water is sucked into the drainage base 4 through the water outlet pipe 23. When the piston plate 7 moves downward... As the volume of the space below decreases and the air pressure increases, the rotating plate 6 of the water outlet pipe 23 closes, and the rotating plate 6 of the drain pipe 5 is opened by high pressure. The accumulated water is discharged to the outside through the drain pipe 5, completing one active drainage cycle. The piston plate 7 is continuously driven to move up and down by the rotating motor 14, and the drainage base 4 can continuously actively discharge the infiltrated water, preventing the water from accumulating in the waterproof base 2 and preventing the water from flowing back into the signal body 1 from the bottom. This ensures that the electronic components inside the signal body 1 are not affected by the water and maintain normal operation.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
