Description

Technical Field

[0001] This utility model relates to the field of drainage mechanism technology, specifically a drainage mechanism for an underpass tunnel. Background Technology

[0002] With the development of urban construction, there is an increasing number of underpasses where the road surface at both ends is much higher than the road surface in the middle of the tunnel. When underpasses are hit by heavy rain, their internal environment faces severe challenges. On the one hand, the rapid water flow can exert a strong impact on the manhole covers, causing them to shift or be washed away. If pedestrians accidentally step into these uncovered drainage wells, accidents can occur, posing a safety hazard. On the other hand, because underpasses are located in low-lying areas, the drainage outlets of the drainage structure are easily blocked by foreign objects such as leaves and plastic strips. Once drainage is obstructed, a large amount of water will quickly accumulate in the tunnel, leading to serious flooding accidents.

[0003] Therefore, a drainage system for underpass tunnels is needed to improve the above-mentioned problems. Utility Model Content

[0004] To address the problem that rapid water flow can exert a strong impact on manhole covers during the operation of drainage systems in underpasses, causing them to shift or be washed away, and posing a safety hazard if pedestrians accidentally step into these uncovered drainage wells, this utility model provides a drainage system for underpasses to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drainage mechanism for an underpass tunnel includes a drainage shell and a water storage shell. The drainage shell is installed on the outer wall of the water storage shell. An installation groove is formed on the outer wall of the drainage shell, and a cover plate is sequentially arranged on the inner wall of the installation groove. A connecting groove is provided on the outer wall of the cover plate. A blocking block is provided at the connection between the drainage shell and the water storage shell and on the inner wall of the drainage shell. The blocking block has a trapezoidal cross-section. A warning component is provided on the inner wall of the water storage shell. A first conduit is provided on the outer wall of the water storage shell. A water pump is installed at one end of the first conduit. A controller is installed on the outer wall of the water pump. A one-way valve is installed at one end of the water pump through a second conduit.

[0007] As a preferred embodiment of this utility model, the warning component includes a limiting slide rail, wherein two sets of the limiting slide rail are provided and are respectively located on the inner walls opposite to each other of the water storage shell, and a sliding block is slidably connected to the inner wall of the limiting slide rail.

[0008] As a preferred embodiment of this utility model, a fixing plate is provided on the inner wall of the sliding block, a float is installed on one side of the fixing plate and on the outer wall of the sliding block, and a first positioning rod is installed on the base surface of the fixing plate.

[0009] As a preferred embodiment of this utility model, a second positioning rod is installed at the port of the first positioning rod, and a first housing is installed on one side of the limiting slide rail at the port of the water storage housing.

[0010] As a preferred embodiment of this utility model, a transverse groove is provided on the outer wall of the first housing, and a limiting sleeve is embedded in the outer wall of the first housing.

[0011] As a preferred embodiment of this utility model, a second positioning rod is slidably connected to the inner wall of the limiting sleeve, and a second housing is installed at one end of the second positioning rod. The outer wall of the second housing is provided with a longitudinal groove, and the second housing is inserted and removed at the port of the first housing.

[0012] As a preferred embodiment of this utility model, the controller is connected to a water pump via a wire and the connection method is electrical connection. Multiple sets of cover plates are provided and are located on the inner wall of the mounting groove, and multiple sets of connecting grooves are provided and are located on the outer wall of the cover plates.

[0013] As a preferred embodiment of this utility model, the floats are provided in multiple sets and are respectively located on the bottom outer wall of the sliding block, the second positioning rod is located directly below the limiting sleeve, and a warning coating is provided on the outer wall of the second shell.

[0014] Compared with existing technologies, this utility model, by setting a warning component in the drainage mechanism of the underpass tunnel, enables the warning component to float up and warn pedestrians when water flows. The float is lifted by the buoyancy of the water, which in turn causes the sliding block to move upward via the fixed plate, driving the first and second positioning rods. At this time, the second positioning rod slides upward on the inner wall of the limiting sleeve. When the first positioning rod pushes out the first housing, it causes the second positioning rod to move the second housing upward. Due to the height of the second housing and the warning coating on its surface, it can serve as a reminder to pedestrians. Furthermore, the fixed plate located in the inner cavity of the water storage housing provides support, thereby solving the problem that the turbulent water flow can generate a strong impact on the manhole cover, causing the manhole cover to shift or be washed away, and the safety problem of pedestrians accidentally stepping into these uncovered drainage wells.

[0015] This invention incorporates a blocking block and a warning component into the drainage mechanism of an underpass tunnel. Solid particles are blocked by the blocking block, causing them to accumulate on one side. Simultaneously, as the float moves upward via the fixed plate and the sliding block, the first positioning rod pushes the first housing out of the inner cavity of the water storage shell through the limiting sleeve. At this point, floating impurities carried by the water flow float out of the water storage shell, allowing the controller to control the water pump to extract water from the inner cavity of the water storage shell. Since the water pump is located in the middle of the water storage shell, blockage of the pump inlet is avoided, improving practicality. This solves the problem that underpass tunnels, due to their low elevation, are prone to having their drainage outlets blocked by leaves, plastic strips, and other foreign objects. Once drainage is obstructed, a large amount of water quickly accumulates in the tunnel, leading to serious flooding accidents. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figure 1-5The drainage mechanism of an underpass tunnel shown includes a drainage shell 1 and a water storage shell 2. The drainage shell 1 is installed on the outer wall of the water storage shell 2. An installation groove 3 is provided on the outer wall of the drainage shell 1, and a cover plate 4 is sequentially provided on the inner wall of the installation groove 3. A connecting groove 5 is provided on the outer wall of the cover plate 4. A blocking block 6 is provided at the connection between the drainage shell 1 and the water storage shell 2 and on the inner wall of the drainage shell 1. The blocking block 6 has a trapezoidal cross-section. A warning component 7 is provided on the inner wall of the water storage shell 2. A first conduit 8 is provided on the outer wall of the water storage shell 2. A water pump 9 is installed at one end of the first conduit 8. A controller 10 is installed on the outer wall of the water pump 9. A one-way valve 12 is installed at one end of the water pump 9 through a second conduit 11.

[0024] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The warning component 7 includes a limiting slide rail 701. Two sets of limiting slide rails 701 are provided and located on opposite inner walls of the water storage shell 2. A sliding block 702 is slidably connected to the inner wall of the limiting slide rail 701. A fixing plate 703 is provided on the inner wall of the sliding block 702. A float 704 is installed on one side of the fixing plate 703, located on the outer wall of the sliding block 702. A first positioning rod 705 is installed on the base surface of the fixing plate 703, and a second positioning rod 706 is installed at the end of the first positioning rod 705. A first housing 707 is installed on one side of the rail 701 and at the port of the water storage housing 2. A transverse groove 708 is provided on the outer wall of the first housing 707. A limiting sleeve 709 is embedded in the outer wall of the first housing 707. A second positioning rod 706 is slidably connected to the inner wall of the limiting sleeve 709. A second housing 710 is installed at one end of the second positioning rod 706. A longitudinal groove 711 is provided on the outer wall of the second housing 710. The second housing 710 is inserted and removed at the port of the first housing 707.

[0025] Based on the above structural features and connection relationships, the controller 10 is connected to the water pump 9 via a wire in an electrical connection manner, which enables the device to be powered on. This allows the controller 10 to control the water pump 9 to operate. Furthermore, the one-way valve 12 located on one side of the water pump 9 can prevent water from flowing back into the pipe, thus improving its practicality.

[0026] The cover plate 4 is provided in multiple sets and is located on the inner wall of the mounting groove 3. The connecting groove 5 is provided in multiple sets and is located on the outer wall of the cover plate 4. The float 704 is provided in multiple sets and is located on the bottom outer wall of the sliding block 702. The second positioning rod 706 is located directly below the limiting sleeve 709. The outer wall of the second housing 710 is provided with a warning coating.

[0027] In this design, the drainage mechanism of the underpass tunnel, during operation, allows water to flow into the inner cavity of the drainage shell 1 through the connecting channel 5. Because a blocking block 6 is installed inside the drainage shell 1, solid particles carried in by the water flow are blocked by the blocking block 6, causing the fixed particles to accumulate on one side of the blocking block 6. Simultaneously, floating debris such as branches flow into the water storage shell 2. At this time, due to the presence of water inside the water storage shell 2, the float 704 experiences buoyancy, causing the float 704 to move upwards via the fixing plate 703, driving the sliding block 702. When the sliding block 702 slides upwards along the inner wall of the limiting slide rail 701, it causes the sliding block 702 to move upwards via the fixing plate 703, driving the... The first positioning rod 705 and the second positioning rod 706 move upward. As the first positioning rod 705 pushes the first housing 707 out of the inner cavity of the water storage housing 2 through the limiting sleeve 709, the floating impurities brought in by the water flow will float out of the water storage housing 2, thereby causing the controller 10 to control the water pump 9 to pump out the water from the inner cavity of the water storage housing 2. At the same time, since the water pump 9 is located in the middle of the water storage housing 2, the inlet of the water pump 9 can be prevented from being blocked, which is more practical. This solves the problem that due to the low terrain of the underpass tunnel, the drainage outlet of the drainage structure is easily blocked by foreign objects such as leaves and plastic strips. Once the drainage is blocked, a large amount of water will quickly accumulate in the tunnel, which will cause a serious flooding accident.

[0028] The water flow within the water storage shell 2 causes the float 704 to be buoyed by the water, which in turn causes the float 704 to move upward via the fixing plate 703, driving the sliding block 702 upward. When the sliding block 702 slides upward on the inner wall of the limiting slide rail 701, it causes the first positioning rod 705 and the second positioning rod 706 to move upward via the fixing plate 703. At this time, the second positioning rod 706 slides upward on the inner wall of the limiting sleeve 709. When the first positioning rod 705 pushes the first shell 707 upward... When pushed out, the second positioning rod 706 will cause the second housing 710 to move upward. Since the second housing 710 is relatively high and its surface is coated with a warning coating, it can serve as a reminder to pedestrians. The fixing plate 703 located in the inner cavity of the water storage housing 2 provides support, thereby solving the problem that the turbulent water flow will have a strong impact on the manhole cover, causing the manhole cover to shift or be washed away. If pedestrians accidentally step into these uncovered drainage wells, accidents may occur, which is unsafe.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
