Description

Technical Field

[0001] This utility model relates to a waterproof structure, specifically a waterproof structure for preventing blockages in road and bridge designs, belonging to the field of road and bridge technology. Background Technology

[0002] Roads and bridges, as the name suggests, are structures used to connect roads and cross obstacles. They play a crucial role in the road transportation system, ensuring not only road continuity and smooth traffic flow but also meeting the travel needs of vehicles, pedestrians, and other road users. The construction of roads and bridges is of great significance for improving traffic conditions and promoting economic development.

[0003] A search revealed a Chinese patent (CN214831896U) disclosing a waterproof structure for road and bridge design. The structure includes a bridge body with multiple water outlets at its upper end. A mounting frame is fixed to the lower side of each outlet, and a motor housing is located at the lower end of the mounting frame. A motor is housed inside the motor housing, and fan blades are located at the upper end of the mounting frame. A baffle is located inside each outlet, and a fixing rod is fixed to the right end of the baffle. A spring is fitted onto the lower outer wall of the threaded rod, and a movable plate is fitted onto the outer wall of the middle section of the threaded rod. A driven wheel is fixed to the end of the threaded rod, and a driving wheel is fixed to the end of the rotating rod. A cavity is formed inside the bridge body relative to the water outlets, and two conductive blocks are symmetrically arranged on one side of the cavity. This invention, by using a baffle, allows the conductive copper blocks to control the motor and rotate the fan blades when impacted by rainwater. This design is reasonable and effectively accelerates the drainage speed of the bridge.

[0004] While the above solutions can effectively accelerate the drainage speed of bridges, the waterproof structure in the aforementioned patents does not have an anti-clogging effect. When the suction force is strong, solid debris in the water will also be sucked up, easily clogging the inlet and affecting the drainage speed. Therefore, we provide an anti-clogging waterproof structure for road and bridge design to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof structure for road and bridge design that prevents blockage, in order to solve the problem that the aforementioned prior art does not have an anti-blockage effect.

[0006] This utility model is achieved through the following technical solution: a waterproof structure for preventing blockages in road bridges, including a main water inlet board. A supporting protective shell is fixedly connected to the lower surface of the main water inlet board. A waterproof DC motor is fixedly connected to the inner wall of the supporting protective shell. A power drive plate is fixedly connected to the output shaft of the waterproof DC motor. A force application linkage plate is rotatably connected to the power drive plate through a positioning post one. The inner wall of the force application linkage plate is rotatably connected to the outer circumferential surface of a positioning post two. One end of the positioning post two is fixedly connected to the bottom of a linkage slider. A cleaning plate is fixedly connected to the top of the linkage slider. The tight fit between the components can clean the debris at the water inlet of the main water inlet board.

[0007] Preferably, restrictive strips are fixedly connected to both sides of the linkage slider, and the restrictive strips are slidably connected in the guide grooves opened in the water inlet main board. The design of the guide grooves ensures the smooth movement of the linkage slider.

[0008] Preferably, the lower surface of the water inlet main board is rotatably connected to a central control linkage plate via a positioning post three. A positioning post two is slidably connected in a movable slot opened in the central control linkage plate. The design of the movable slot facilitates the normal movement of the positioning post two.

[0009] Preferably, a backup power supply is fixedly connected to the inner wall of the supporting protective shell. The backup power supply is a well-known technology and will not be described in detail.

[0010] Preferably, a water level monitoring chamber is fixedly connected to the upper surface of the water inlet main board. The water level monitoring chamber has a water inlet trough. The design of the water inlet trough ensures that when water accumulates on the bridge surface, the water level in the water level monitoring chamber will rise synchronously.

[0011] Preferably, the water level monitoring chamber is fixedly connected to a processor, and a water level sensor is fixedly connected to one side of the processor. The water level sensor is a known technology and will not be described in detail.

[0012] Preferably, a mounting base is fixedly connected to one side of the water inlet main board, and the mounting base has bolt holes. The design of the bolt holes facilitates the installation and mounting of the water inlet main board.

[0023] This utility model provides a waterproof structure for road and bridge design to prevent blockage.

[0024] Please see Figure 1 The system includes a main water inlet board 1, with a mounting base 19 fixedly connected to one side. The mounting base 19 has bolt holes. The mounting base 19 facilitates the installation of the entire waterproof structure on a designated plane of a road or bridge. During installation, it can be directly fixed with bolts, eliminating the need for on-site drilling and tapping, and speeding up the assembly process. For example, in mass production, parts with pre-machined threaded holes can be "ready to use immediately" without the need to carry tapping tools on-site, making it particularly suitable for confined environments such as high altitudes and narrow spaces.

[0025] Please see Figure 1 and Figure 5A water level monitoring chamber 16 is fixedly connected to the upper surface of the water inlet motherboard 1. The water level monitoring chamber 16 has a water inlet trough. The purpose of setting up the water level monitoring chamber 16 is that when water accumulates on the surface of the road or bridge, the water level in the water level monitoring chamber 16 will also rise as the water level rises until the water level sensor 18 is completely submerged. A processor 17 is fixedly connected to the water level monitoring chamber 16. A water level sensor 18 is fixedly connected to one side of the processor 17. The water level sensor 18 is set up to determine the water level by detecting changes in capacitance value. It is mainly composed of two electrodes. When the medium between the electrodes changes, the capacitance value changes accordingly. That is, when there is no water, the medium between the electrodes is air; when the water level rises, water replaces air, and the capacitance value increases significantly. After the circuit detects the change, it outputs a signal. The output signal is received by the processor 17. After processing the signal information, the processor 17 sends an instruction to the backup power supply 15. The processor 17 and the water level sensor 18 are existing known technologies and will not be described in detail in this application.

[0026] Please see Figure 3 The lower surface of the water inlet main board 1 is rotatably connected to the central control linkage plate 12 via positioning post three 14. The purpose of setting positioning post three 14 is to apply a control effect to the central control linkage plate 12, so that the central control linkage plate 12 rotates around positioning post three 14 as an axis without falling off. Positioning post two 7 is slidably connected in the movable through slot 13 opened in the central control linkage plate 12. When the central control linkage plate 12 is kept stable, the movement of positioning post two 7 can make the central control linkage plate 12 swing around positioning post three 14 as an axis, thereby controlling the movement of another identical linkage slider 8. At this time, the two linkage sliders 8 move in opposite directions.

[0027] Please see Figure 1 and Figure 2 The lower surface of the water inlet motherboard 1 is fixedly connected to a support and protective shell 2. The support and protective shell 2 can provide support for multiple components. The inner wall of the support and protective shell 2 is fixedly connected to a backup power supply 15. The backup power supply 15 is directly connected to the electrical components in this application and can provide effective energy for the waterproof DC motor 3, the processor 17, and the water level sensor 18. The backup power supply 15 is existing known technology and will not be described in detail.

[0028] Please see Figure 2 A waterproof DC motor 3 is fixedly connected to the inner wall of the protective shell 2. The output shaft of the waterproof DC motor 3 is fixedly connected to the power drive plate 4. The purpose of setting up the waterproof DC motor 3 is to effectively provide sufficient power support for the rotation of the power drive plate 4. The core principle of the waterproof DC motor 3 is to prevent moisture, water pressure or water mist from entering the motor through special design and material selection, thereby avoiding problems such as short circuit, corrosion or insulation failure. The waterproof DC motor 3 is a well-known technology and will not be described in detail.

[0029] Please see Figure 2 and Figure 3 The power drive plate 4 is rotatably connected to the force application linkage plate 6 via the positioning post 1 5. The positioning post 1 5 is set so that the force application linkage plate 6 moves around the positioning post 1 5 as an axis. The inner wall of the force application linkage plate 6 is rotatably connected to the outer circumference of the positioning post 2 7. When the positioning post 2 7 remains stable, the movement of the force application linkage plate 6 will pull the positioning post 2 7 to translate. One end of the positioning post 2 7 is fixedly connected to the bottom of the linkage slider 8. The positioning post 2 7 and the linkage slider 8 maintain the linkage effect.

[0030] Please see Figure 3 and Figure 4 The linkage slider 8 is fixedly connected to two sides with limiting strips 10. The limiting strips 10 are slidably connected in the guide grooves 11 opened in the water inlet main board 1. The purpose of setting the limiting strips 10 is to allow the linkage slider 8 to slide at the water inlet of the water inlet main board 1 without jamming or getting stuck. The top of the linkage slider 8 is fixedly connected to a cleaning plate 9. The linkage slider 8 and the cleaning plate 9 maintain a linkage effect. The cleaning plate 9 will move with the linkage slider 8. The movement of the cleaning plate 9 can clean the solid debris on the surface of the water inlet main board 1 and prevent solid debris from clogging the water inlet of the water inlet main board 1.

[0031] Working principle: During use, the mounting base 19 is installed on the pre-reserved position on the road and bridge surface using bolts, thus completing the installation of the waterproof structure. Normal water flow will flow out from the inlet of the main water inlet 1, preventing rainwater from seeping into the bridge body and piers, extending the life of the road and bridge. When the inlet of the main water inlet 1 becomes blocked, the water level on the road and bridge surface will rise, causing the water level in the water level monitoring chamber 16 to rise synchronously. When the water completely submerges the water level sensor 18, the water level sensor 18 will send a signal to the processor 17. After the processor 17 processes the information, it will send a signal to the backup power supply 15. The backup power supply 15 will provide energy to the waterproof DC motor 3, causing the waterproof DC motor 3 to start and drive the motor. The drive plate 4 begins to move in a circular motion. Under the action of the positioning post 1 5, the force-applying linkage plate 6 begins to move. At this time, the linkage slider 8, which is connected to the positioning post 2 7, is restricted by the water inlet main board 1 through the limiting bar 10. Therefore, when the position of the force-applying linkage plate 6 changes, the linkage slider 8 will be pulled to move horizontally through the positioning post 2 7, so that the cleaning plate 9 will move horizontally at the same time. The cleaning plate 9 will clean the solid debris at the water inlet of the water inlet main board 1, thereby ensuring the smooth flow of drainage. At this time, due to the movement of the positioning post 2 7, the central control linkage plate 12 will rotate around the positioning post 3 14 as the axis, thereby causing the other cleaning plate 9 to move horizontally, so that it can clean the two positions at the water inlet of the water inlet main board 1, ensuring the smooth flow of the water inlet of the water inlet main board 1.
