Description

Technical Field

[0001] The utility model belongs to the technical field of rail transportation engineering, and in particular relates to a waterproof drainage device for a subway tunnel. Background Art

[0002] Subways are typically located below ground level, creating relatively confined spaces characterized by secrecy, isolation, and a high density of personnel and equipment, making evacuation and rescue difficult. Subways connect to the outside world primarily through ventilation shafts, entrances and exits, and tunnels. Therefore, when urban flooding occurs, water flows primarily into the subway, rapidly spreading throughout the entire connected area.

[0003] In order to prevent rainwater from flowing back, waterproof doors are usually installed in the platform area and flooding area in the subway tunnel to ensure the safety of passengers.

[0004] When the matching groove under the currently used waterproof door is engaged with the outside of the track body, the engagement tightness between the matching groove and the track body is insufficient, which easily causes water leakage. This phenomenon is not conducive to ensuring the accuracy of the water control process when the opening and closing of the pressure relief port is manually controlled. However, when the matching groove is engaged with the outside of the track body and the sealing inner rubber strip contacts the track body to play a water-blocking function, the water on the track body can be sealed and controlled, making it difficult to overflow. However, some slag and foreign matter will adhere to the surface of the track body in a water-accumulated state, so that the sealing inner rubber strip will be squeezed and damaged by the sharp surface of the foreign matter when the matching groove is engaged with the track body, and the water-blocking function of the waterproof door cannot be guaranteed. Utility Model Content

[0005] In response to the defects or shortcomings in the existing technology, the utility model provides a subway tunnel waterproof drainage device, which can clean up some slag and foreign objects attached to the surface of the track body in a water-logged state, so that when the matching groove is engaged with the track body, the sealing inner strip will not be squeezed and damaged by the sharp surface of the foreign objects, thereby effectively ensuring the water-blocking function of the waterproof door.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0011] Furthermore, side inner grooves are symmetrically opened between the left and right inner walls of the scraping U-shaped frame, and the inner wall of the side inner groove is fixedly connected to an electric push inner rod, and the output end of the electric push inner rod is arranged opposite to the opening of the side inner groove.

[0012] Furthermore, the output end of the electric push inner rod is fixedly connected to a pressure-bearing transverse plate, and rubber water-blocking baffles are symmetrically hinged on both sides of the opening of the side inner slot, and the pressure-bearing transverse plate and the two rubber water-blocking baffles are slidably connected.

[0013] Furthermore, the rubber water-blocking baffle and the inner side slot are hinged via a self-rebounding hinge.

[0014] Furthermore, the rubber water-blocking baffle is adapted to the grooves on both sides of the track body.

[0015] Furthermore, the top of the waterproof gate is fixedly connected to a top plate, and the left and right sides of the upper surface of the top plate are connected to a winch via a sling.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] A typical implementation of the present invention is as follows: Figure 1 and Figure 2 As shown, a waterproof drainage device for a subway tunnel includes a waterproof gate 1, which is arranged above a track body 5. Matching grooves 8 are symmetrically opened on the left and right sides of the lower end of the waterproof gate 1. The matching grooves 8 are arranged corresponding to the two track bodies 5. An upper inner groove 10 is opened on the top of the matching groove 8. A spring 11 is fixedly connected to the top surface of the upper inner groove 10. The end of the spring 11 away from the upper inner groove 10 is fixedly connected to a bottom plate 12. Figure 6As shown, the front and rear ends of the bottom pair of plates 12 are symmetrically fixedly connected with micro electric push rods 13 , and the output ends of the micro electric push rods 13 are fixedly connected with the scraping U-shaped frame 9 .

[0030] The scraping U-shaped frame 9 is located inside the matching groove 8 . A sealing inner rubber strip 15 is provided between the scraping U-shaped frame 9 and the matching groove 8 . The sealing inner rubber strip 15 is fixed on the inner wall of the matching groove 8 .

[0031] like Figure 3 As shown, side inner grooves 16 are symmetrically opened between the left and right inner walls of the scraping U-shaped frame 9, and the inner wall of the side inner groove 16 is fixedly connected with an electric push inner rod 19, and the output end of the electric push inner rod 19 is arranged opposite to the opening of the side inner groove 16, and the output end of the electric push inner rod 19 is fixedly connected with a pressure-bearing cross plate 18, and rubber water-blocking baffles 17 are symmetrically hinged on both sides of the opening of the side inner groove 16, and the pressure-bearing cross plate 18 is slidably connected to the two rubber water-blocking baffles 17, and the rubber water-blocking baffle 17 and the side inner groove 16 are hinged by a self-rebounding hinge.

[0032] The rubber water-blocking baffle 17 is adapted to the grooves 14 on both sides of the track body 5, the scraping U-shaped frame 9 can be engaged on the outside of the track body 5, and the scraping U-shaped frame 9 is slidingly connected to the outer wall of the track body 5, and the rubber water-blocking baffle 17 can be engaged in the grooves 14 on both sides of the track body 5, and the extrusion force generated by its elastic deformation is used to seal both sides of the track body 5.

[0033] The top of the waterproof gate 1 is fixedly connected to a top plate 3 , and the left and right sides of the upper surface of the top plate 3 are connected to a winch through a sling 2 .

[0034] When in use, a winch is used to drive the waterproof gate 1 down, and the matching slots 8 on both sides of the bottom of the waterproof gate 1 are respectively sleeved on the outside of the two track bodies 5 to block the platform area and the irrigation area in the subway tunnel, thereby playing a water-blocking function. Since the initial state of the spring 11 in the matching slot 8 is the extended state, the scraping U-shaped frame 9 protrudes below the matching slot 8. When the waterproof gate 1 descends at a uniform speed, the scraping U-shaped frame 9 first contacts the outside of the track body 5, and uses the micro-electric push rod 13 to drive the two scraping U-shaped frames 9 to scrape back and forth outside the track body 5 to scrape off the slag and foreign matter attached to the track body 5, avoiding some slag and foreign matter adhering to the surface of the track body 5 in the water accumulation state, so that the sealing inner strip 15 will not be squeezed and damaged when the matching slot 8 is engaged with the track body 5, effectively ensuring the water blocking efficiency of the waterproof gate 1. As the waterproof gate 1 continues to descend, the two scraping U-shaped frames 9 can gradually move into the matching slot 8 accompanied by the squeezing of the spring 11, and the outer surface of the scraping U-shaped frame 9 contacts the sealing inner strip 15, thereby ensuring the sealing of the waterproof gate 1.

[0035] like Figure 4As shown, the waterproof gate 1 is also provided with a plurality of pressure relief holes 4, which are divided into two rows and evenly arranged on the waterproof gate 1 from top to bottom. The pressure relief holes 4 are externally connected to an opening and closing control mechanism, which can be opened and closed manually. By regulating the water height on both sides of the waterproof gate 1, the water pressure on both sides of the waterproof gate 1 is adjusted to avoid a hard squeezing of the waterproof gate 1 caused by an excessively large water pressure difference on both sides.

[0036] Since the track body 5 is I-shaped and grooves 14 are provided on both sides thereof, the accumulated water on both sides of the waterproof gate 1 will flow out from the grooves 14, thereby affecting the accuracy of the control. Therefore, after the scraper U-shaped frame 9 is reset, the electric push inner rod 19 pushes the pressure-bearing cross plate 18, and the pressure-bearing cross plate 18 pushes the two rubber water-blocking baffles 17 outward into the grooves 14 on both sides of the track body 5. The grooves 14 are closed by the rubber water-blocking baffles 17 to play a water-blocking role. The two rubber water-blocking baffles 17 are pushed by the pressure-bearing cross plate 18, which not only can push the rubber water-blocking baffles 17 to the specified position, but also can play a lateral pressure-bearing role between the two rubber water-blocking baffles 17, so that the rubber water-blocking baffles 17 are more stably arranged in the grooves 14 on both sides of the track body 5.

[0037] like Figure 5 As shown, vertical slots 6 are symmetrically provided on the front and rear sides of the waterproof gate 1. A liquid level detector 7 is installed in the vertical slot 6. The liquid level detector 7 is located between the two water discharge holes 4. By setting the liquid level detector 7, the water level conditions on both sides of the waterproof gate 1 can be detected, which is helpful for the staff to understand the water blocking conditions near the waterproof gate 1 more intuitively.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
