Description

Technical Field

[0001] This invention relates to the field of traffic drainage system technology, and more specifically, to a wireless electric shut-off valve for bridges and an environmentally friendly bridge drainage system. Background Technology

[0002] With the increasing number of bridges spanning rivers and seas, many vehicles pass over them daily, including numerous tanker trucks carrying various hazardous chemicals. If such vehicles are involved in accidents, causing leaks of the hazardous chemicals they are carrying, the leaked liquids will flow directly into rivers or the sea. In the event of such an accident, it is necessary to implement various labor-intensive and resource-intensive methods, such as sealing off the river, to handle the contaminated liquids. The treatment costs are extremely high, and if the treatment is not timely or thorough, it will cause very serious environmental pollution problems.

[0003] Traditional bridge drainage systems are designed as "point drainage," meaning that a straight drainage hole is opened at regular intervals (usually 5-10 meters) on the roads on both sides of the bridge deck, allowing any liquid to be discharged directly into the river (sea).

[0004] To address this, patent CN201510506775.0 discloses a bridge leakage prevention and drainage system and its control method. This patent involves setting linear drainage ditches on the bridge deck, installing drainage ditch covers on the ditches, and each linear drainage ditch having an outlet, with a cover installed above the outlet. The solenoid valve control system includes several solenoid valves, several field control boxes, a central control room, power lines, solenoid valve cables, and communication lines. The solenoid valves are installed near the outlet of each linear drainage ditch, and are connected to their respective field control boxes. The power lines for the field control boxes are borrowed from streetlights. The central control room is connected to each field control box via communication lines. The cover is equipped with an actuating rod, forming a valve. The actuating rod is connected to the solenoid valve. When the solenoid valve receives a closing signal, it automatically actuates the cover to close the outlet. Under normal circumstances, the cover is in contact with the lower surface of the drainage ditch cover, indicating normal drainage.

[0005] The above-mentioned patents have encountered the following problems in practical applications:

[0006] 1. Since the cover is laid on the surface of the bridge, it will inevitably be run over by vehicles, making it very easy to be damaged. A damaged cover will not fit properly against the underside of the drainage ditch cover, and harmful liquids from the bridge surface can still be discharged directly from the drainage outlet.

[0007] 2. The control of the cap relies entirely on manual operation, and it cannot effectively and promptly stop drainage automatically.

[0008] 3. Communication control requires the connection of various communication pipelines, which is a large project during construction, time-consuming and labor-intensive, and repairs also require significant costs if the pipelines are damaged. Summary of the Invention

[0009] In view of the above-mentioned technical problems in the prior art, this application proposes a wireless electric water shut-off valve for bridges, which aims to solve the problem that the cover is easily damaged and cannot automatically prevent drainage pollution.

[0026] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0027] See Figure 1 As shown, the wireless electric shut-off valve for bridges in this application mainly includes: a drainage pipe 1, a shell 2, a motor 3, a mechanical linkage structure 4, a control center 5, a valve cover 62, and other structures.

[0028] The inlet 101 of the drain pipe 1 connects to the drain outlet of the bridge deck. A valve 61 is installed at the outlet 102 of the drain pipe 1 via a flange, and a valve cover 62 is mounted on the valve to block drainage from the outlet 102. The drain pipe 1 is designed in a curved shape to guide the drainage direction and reduce the force exerted on the valve cover 62 by accumulated water, thus extending its service life. A sealing element 7 is provided at the valve cover 62 and the valve 61 to further enhance the sealing effect.

[0029] Motor 3 is connected to mechanical linkage structure 4. Motor 3 serves as the power source for mechanical linkage structure 4. The end of mechanical linkage structure 4 is connected to valve cover 62. Under the drive of motor 3, mechanical linkage structure 4 moves valve cover 62 to open and close drain pipe 1. The mechanical linkage structure 4 is connected to the base of motor 3 via a fixed bracket 12.

[0030] As shown in the figure, the mechanical linkage structure 4 includes a drive rod 41, a linkage plate 42, and a connecting plate 43. The drive rod 41 is connected to the motor 3 at its tip, and the motor 3 drives the drive rod 41 to rotate. In this embodiment, the linkage plate 42 is a parallelogram structure, but it is not limited to this structure. A first connection point 421 is provided at the bottom corner of the linkage plate 42, and the first connection point 421 is connected to the fixed bracket 12 by a pin. The linkage plate 42 can rotate freely about the first connection point 421. A movable limiting groove 422 is provided at the upper end of the linkage plate 42, and the end of the drive rod 41 is limited within the movable limiting groove 422. The movable limiting groove 422 includes a straight groove 4221, a downward curved groove 4222, and a lifting groove 4223, with the lifting groove 4223 being closer to the fixed bracket 12 and the first connection point 421. Additionally, the linkage plate 42 is a one-piece or two-piece symmetrical combination structure, and the top of the linkage plate 42 is provided with a slot to allow the drive rod 41 to slide. The connecting plate 43 is fixedly connected to the linkage plate 42, and the connecting plate 43 is fixedly connected to the valve cover 62. The connecting plate 43 can drive the valve cover 62 to move under the drive of the linkage plate 42.

[0031] See Figure 2 and Figure 3 As shown, the motor 3 drives the drive rod 41 to rotate. When the end of the drive shaft 41 moves to the lifting groove, the drive shaft 41 generates a tensile force on the linkage plate 42. The linkage plate 42 moves upward about the first connection point 421, which in turn drives the connecting plate 43 to move upward and open the valve cover 62. When the end of the drive shaft 41 moves to the straight groove 4221, the drive shaft 41 generates a pushing force on the linkage plate 42. The linkage plate 42 moves downward about the first connection point 421, which in turn drives the connecting plate 43 to move downward and close the valve cover 62.

[0032] As shown in the figure, in this embodiment, the control center 5 is located near the motor 3. The control center 5 is electrically connected to and controls the motor 3. The control center 5 includes, but is not limited to, a pH determination module and a wireless communication control module. The pH determination module is connected to a pH sensor and receives real-time detection data transmitted by the pH sensor. The pH determination module determines whether the real-time monitoring data is within the set standard pH value range and sends the determination result to the wireless communication control module. The wireless communication control module is connected to and receives the determination result transmitted by the pH determination module, and controls whether the motor 3 moves according to the result. The setup of the pH determination module and the wireless communication control module can achieve the purpose of automatically controlling the opening and closing of the valve.

[0033] In addition, to further ensure that the valve cover 62 locks the outlet 102, this application provides a self-locking device 8, which is connected to the mechanical linkage structure 4. Under the drive of the mechanical linkage structure 4, the self-locking device 8 unlocks or locks the valve cover 62 and the outlet 102 of the drain pipe.

[0034] Combination Figure 2 and Figure 3 As shown, the self-locking device 8 includes a locking rod 81, a lock body 82, and a top block 83. As shown, the locking rod 81 includes a second connection point 811 in the middle, a vertical structure 812 at the top, and a connecting part 813 at the bottom. The second connection point 811 is fixed to the connecting plate 43 by a pin, and the locking rod 81 can rotate freely about the second connection point 811. The vertical structure 812 corresponds to the end of the empty groove. When the end of the driving rod 41 moves to the end of the straight groove 4221, the end of the driving rod 41 pushes against the vertical structure 812, causing the locking rod 81 to rotate about the second connection point 811. The connecting part 813 connects to the lock body 82. The bottom of the lock body 82 has a slot 821, the shape and size of which match the valve cover 62 and the valve 61. The top block 83 passes through the lower curved groove 4222 and is inserted into the connecting plate 42, with the bottom of the top block 83 abutting against the lock body 82.

[0035] When the end of the drive rod 41 pushes against the vertical structure 812 and moves downward, the connecting part 813 drives the lock body 82 to move upward, and the lock body 82 locks the valve cover 62 and the valve 61 together. When the drive rod 41 moves to the lower bend groove 4222, the drive rod 41 presses against the top block 83, the top block 83 pushes against the lock body 82, and the lock body 82 moves downward, unlocking the valve.

[0036] The outer casing 2 covers the mechanical linkage structure 4, the motor 3, the pH determination module, and the wireless communication control module. The outer casing 2 primarily serves to provide waterproofing, sun protection, and corrosion resistance, thus extending their service life. Furthermore, the wireless communication control module and pH determination module of this application can be connected to the control center in a fixed manner to simplify the installation process, or in a plug-in manner to facilitate subsequent maintenance.

[0037] Please see again Figure 2 As shown, this is an environmentally friendly drainage system for bridges according to this application.

[0038] The bridge's environmentally friendly drainage system includes drainage ditches 9 linearly arranged on bridge deck B, drainage ditch covers 10 on the drainage ditches 9, and drainage outlets 11 spaced out at intervals. The wireless electric shut-off valve A for bridges in this application is fixed below bridge deck 12 in the form of a fixing bracket or frame, corresponding one-to-one with each drainage outlet 11. The inlet 101 of the drainage pipe connects to the drainage outlets 11 on the bridge deck. Simultaneously, a pH sensor is installed in the drainage ditch, with the pH sensor 1.5-25 meters away from its corresponding drainage outlet to provide a reaction distance for the wireless electric shut-off valve A. Installing the wireless electric shut-off valve A below the bridge deck avoids damage from vehicle traffic, extends its service life, and reduces unnecessary wear and tear.

[0039] Furthermore, this application includes a central control system that wirelessly connects to and controls the wireless communication control modules of the wireless electric shut-off valves used on each bridge. The central control system can be connected to a central control room and displayed visually to a control console.

[0040] In summary, the wireless electric shut-off valve and bridge environmental protection drainage system of this application eliminate the use of a cover, allowing the valve to be installed below the bridge deck to avoid damage that could prevent the drainage of polluted water. At the same time, this application uses a pH sensor combined with a wireless communication control module to achieve automated control and reduce construction costs and complexity.
