Description

Technical Field

[0001] This utility model relates to the field of urban drainage technology, specifically to a rapid drainage device for urban pipe networks. Background Technology

[0002] With the acceleration of urbanization and the increasing proportion of hard surfaces, rainwater infiltration capacity has significantly decreased. Coupled with the frequent occurrence of extreme weather events globally (such as torrential rains and typhoons), traditional urban drainage networks often cause flooding problems due to insufficient drainage efficiency. Therefore, there is a need for a high-efficiency, intelligent, and highly adaptable rapid drainage device.

[0003] In the prior art, utility model patent with patent number CN202223606015.1 discloses a rapid drainage device for urban pipe networks based on a submersible pump, including an urban pipe network, a manhole cover, a sewer pipe, a water storage tank, and an inlet pipe; the urban pipe network is provided with a manhole cover on top, a sewer pipe is provided on one side of the urban pipe network, and a water storage tank is provided on the other side. The sewer pipe is L-shaped and is connected to the water storage tank through an inlet pipe; a trapezoidal platform is provided on the upper side of the bottom of the sewer pipe and is located directly below the manhole cover. One end of a metal mesh cage is connected to the upper side of the trapezoidal platform, and the other end is connected to the pipe wall of the sewer pipe, so that a cuboid area is formed between the metal mesh cage and the sewer pipe. A submersible pump is provided in the cuboid area and is connected to the upper side of the trapezoidal platform. A water flow sensor is provided on the top of the submersible pump, and the submersible pump and the water flow sensor are respectively connected to a controller.

[0004] The urban pipe network rapid drainage device provided by the above patent uses a submersible pump to transport sewage to a storage tank, which can relieve the drainage pressure of the inlet pipe; however, during the drainage process, there is not only the problem of excessive water flow leading to high drainage pressure in the drainage pipe, but also the possibility of sedimented garbage in the sewage. When a large amount of garbage accumulates in the drainage pipe, it will cause the drainage pipe to become blocked. The above device lacks a structure to prevent the drainage pipe from becoming blocked and needs further improvement. Utility Model Content

[0005] The purpose of this invention is to provide a rapid drainage device for urban pipe networks, which aims to improve the problem that existing rapid drainage devices for urban pipe networks lack a structure to prevent blockage of drainage pipes.

[0006] This utility model is implemented as follows: A rapid drainage device for urban pipe networks includes a well body and a drainage pipe, as well as a lifting device and a filter screen. The drainage pipe is installed through the middle of the side of the well body, and a wellhead mounting seat is installed at the upper end of the well body. A well cover is installed at the upper end of the wellhead mounting seat, and a filter screen extending into the well body is installed at the lower end. A lifting device is installed inside the wellhead mounting seat below the well cover. The lifting device includes a rotating rod and a lifting rod, both of which are rotatably installed in the wellhead mounting seat at the middle and are connected end to end. A water receiving plate is installed at the end of the rotating rod away from the lifting rod, and the end of the lifting rod away from the rotating rod abuts against the lower end face of the well cover.

[0007] Preferably, the well body includes an installation opening, and the side of the wellhead mounting seat is provided with an installation edge that is adapted to the installation opening. The wellhead mounting seat is seated in the installation opening through the installation edge.

[0008] Preferably, the well body further includes a sedimentation chamber, and the portion of the well body below the drainage pipe is configured as a sedimentation chamber, with the lower end of the filter screen extending into the sedimentation chamber.

[0009] Preferably, the wellhead mounting base includes a well cover opening, the upper end of the wellhead mounting base is provided with a well cover opening, a first mounting shaft is provided in the well cover opening, a rotating hole is provided on one side of the well cover, the rotating hole is installed on the first mounting shaft, and the well cover is rotatably disposed in the well cover opening.

[0010] Preferably, the rotating rod includes a pressure rod, and a second mounting shaft is provided inside the wellhead mounting base. The rotating rod is rotatably mounted in the second mounting shaft at its middle position. A water receiving plate is provided at one end of the rotating rod, and a pressure rod is provided at the other end. The water receiving plate is located below the well cover, and the pressure rod abuts against the end of the top rod near the rotating rod.

[0011] Preferably, the top rod includes a connecting rod; a pair of top rods are symmetrically arranged and located on both sides of the rotating rod, and the middle of each pair of top rods is rotatably mounted on the wellhead mounting base, and the end near the rotating rod is connected to the connecting rod, and the other end abuts against the lower end face of the well cover; the pressure rod presses against the connecting rod.

[0012] Preferably, the push rod further includes a rotating nail, which is rotatably inserted into the middle of the push rod and is fixedly installed on the inner wall of the wellhead mounting base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model sets the drain pipe in the middle of the well body, and sets a sedimentation chamber for settling garbage below the drain pipe. This can prevent garbage from accumulating at the opening of the drain pipe. At the same time, the garbage is filtered by the filter screen to prevent garbage from entering the drain pipe and prevent the drain pipe from becoming blocked.

[0015] 2. By setting up a lifting device, when the drainage pressure is too high, the impact of the water flow on the water-receiving plate can drive the rotating rod to rotate. The rotating rod drives the lifting rod to abut against one end of the manhole cover and lift it up, thereby opening the manhole cover to a certain size, thus increasing the drainage efficiency.

The drainage pipe 2 is installed through the middle of the side of the well body 1, and a wellhead mounting seat 3 is installed at the upper end of the well body 1. The well body 1 includes an installation opening 101 and a sedimentation chamber 102. The side of the wellhead mounting seat 3 is provided with an installation edge 301 that matches the installation opening 101, and the wellhead mounting seat 3 is seated in the installation opening 101 through the installation edge 301. A well cover 4 is provided at the upper end of the wellhead mounting seat 3, and a filter screen 6 extending into the interior of the well body 1 is provided at the lower end. The part of the well body 1 below the drainage pipe 2 is set as the sedimentation chamber 102, and the lower end of the filter screen 6 extends into the sedimentation chamber 102. By setting the drainage pipe 2 in the middle of the well body 1, a sedimentation chamber 102 can be reserved below the drainage pipe 2, allowing solid waste in the water to be deposited in the sedimentation chamber 102, avoiding deposition at the opening of the drainage pipe 2 and preventing blockage of the drainage pipe 2. The filter screen 6 can filter sewage entering the well body, allowing cleaning workers to easily remove solid waste directly through the filter screen 6; it can also filter sewage entering the drain pipe 2. A lifting device 5 is installed inside the wellhead mounting base 3, located below the well cover 4. The wellhead mounting base 3 includes a well cover opening 302, with the opening 302 located at its upper end. A first mounting shaft 303 is installed in the well cover opening 302. A rotating hole 401 is provided on one side of the well cover 4, and the rotating hole 401 is mounted on the first mounting shaft 303. The well cover 4 is rotatably mounted in the well cover opening 302. The well cover 4 is rotatably mounted in the well cover opening 302 at one end, allowing it to be opened by rotating it on one side.

[0026] like Figure 1 and Figure 5As shown, the lifting device 5 includes a rotating rod 501 and a lifting rod 504. Both the rotating rod 501 and the lifting rod 504 are rotatably installed in the wellhead mounting base 3 at their center, and are arranged end-to-end. A water receiving plate 502 is provided at the end of the rotating rod 501 away from the lifting rod 504, and the end of the lifting rod 504 away from the rotating rod 501 abuts against the lower end face of the well cover 4. The rotating rod 501 includes a pressure rod 503. A second mounting shaft 304 is provided inside the wellhead mounting base 3. The rotating rod 501 is rotatably installed in the second mounting shaft 304 at its center. A water receiving plate 502 is provided at one end of the rotating rod 501, and a pressure rod 503 is provided at the other end. The water receiving plate 502 is located below the well cover 4, and the pressure rod 503 presses against the end of the lifting rod 504 near the rotating rod 501. The push rod 504 includes a connecting rod 506; a pair of push rods 504 are symmetrically arranged and located on both sides of the rotating rod 501. Each pair of push rods 504 is rotatably mounted on the wellhead mounting base 3 at its center, and the end closest to the rotating rod 501 is connected to the connecting rod 506, while the other end abuts against the lower end face of the well cover 4; the pressure rod 503 presses against the connecting rod 506. The push rod 504 also includes a rotating pin 505, which is rotatably inserted into the center of the push rod 504 and is fixedly mounted on the inner wall of the wellhead mounting base 3. When sewage enters the well body 1, the sewage impacts the water receiving plate 502. The water receiving plate 502 rotates downward due to the impact of the water flow. At the same time, the upper pressure rod 503 drives the connecting rod 506 to move downward, causing the top rod 504 to rotate. Thus, the end of the top rod 504 away from the connecting rod 506 lifts the well cover 4, allowing the well cover 4 to open at a certain angle, increasing the water intake speed of the well body 1 and accelerating the drainage speed.

[0027] Example 2

[0028] like Figures 1-4 As shown, a rapid drainage device for urban pipe networks includes a well body 1 and a drainage pipe 2, as well as a jacking device 5 and a filter screen 6. The drainage pipe 2 is installed through the middle of the side of the well body 1, and a wellhead mounting seat 3 is installed at the upper end of the well body 1. The well body 1 includes an installation opening 101, and the side of the wellhead mounting seat 3 is provided with an installation edge 301 that matches the installation opening 101. The wellhead mounting seat 3 is seated in the installation opening 101 through the installation edge 301. A well cover 4 is provided at the upper end of the wellhead mounting seat 3, and a filter screen 6 extending into the interior of the well body 1 is provided at the lower end. The well body 1 also includes a sedimentation chamber 102, and the part of the well body 1 below the drainage pipe 2 is configured as the sedimentation chamber 102. The lower end of the filter screen 6 extends into the sedimentation chamber 102. A lifting device 5 is provided inside the wellhead mounting base 3 at a position below the well cover 4; the wellhead mounting base 3 includes a well cover opening 302, the upper end of the wellhead mounting base 3 is provided with a well cover opening 302, a first mounting shaft 303 is provided in the well cover opening 302, a rotating hole 401 is provided on one side of the well cover 4, the rotating hole 401 is installed on the first mounting shaft 303, and the well cover 4 is rotatably positioned in the well cover opening 302.

[0029] like Figure 1 and Figure 5 As shown, the lifting device 5 includes a rotating rod 501 and a lifting rod 504. Both the rotating rod 501 and the lifting rod 504 are rotatably installed in the wellhead mounting base 3 at their center, and are arranged end-to-end. A water receiving plate 502 is provided at the end of the rotating rod 501 away from the lifting rod 504, and the end of the lifting rod 504 away from the rotating rod 501 abuts against the lower end face of the well cover 4. The rotating rod 501 includes a pressure rod 503. A second mounting shaft 304 is provided inside the wellhead mounting base 3. The rotating rod 501 is rotatably installed in the second mounting shaft 304 at its center. A water receiving plate 502 is provided at one end of the rotating rod 501, and a pressure rod 503 is provided at the other end. The water receiving plate 502 is located below the well cover 4, and the pressure rod 503 presses against the end of the lifting rod 504 near the rotating rod 501. The push rod 504 includes a connecting rod 506; a pair of push rods 504 are symmetrically arranged and located on both sides of the rotating rod 501. Each pair of push rods 504 is rotatably mounted on the wellhead mounting base 3 at its center, and the end closest to the rotating rod 501 is connected to the connecting rod 506, while the other end abuts against the lower end face of the well cover 4; the pressure rod 503 presses against the connecting rod 506. The push rod 504 also includes a rotating pin 505, which is rotatably inserted into the center of the push rod 504 and is fixedly mounted on the inner wall of the wellhead mounting base 3.

[0030] The working principle of this invention is as follows: When sewage enters the well body 1, it impacts the water receiving plate 502. The water receiving plate 502 rotates downwards due to the water flow, simultaneously causing the connecting rod 506 to move downwards via the upper pressure rod 503. This causes the top rod 504 to rotate, lifting the well cover 4 at the end of the top rod 504 away from the connecting rod 506, allowing the well cover 4 to open at a certain angle, increasing the water inflow speed of the well body 1 and accelerating the drainage speed. Simultaneously, solid waste in the water is filtered through the filter screen 6. When the water level in the well body 1 reaches the drain pipe 2, the water flows out through the drain pipe 2, and the solid waste settles in the sedimentation chamber 102, preventing accumulation at the drain pipe 2 opening and thus avoiding blockage. When it is necessary to clean the waste in the well body 1, the solid waste can be directly collected and removed through the filter screen 6.

[0031] In summary, this utility model, by placing the drain pipe 2 in the middle of the well body 1 and providing a sedimentation chamber 102 for settling waste below the drain pipe 2, can prevent waste from accumulating at the opening of the drain pipe 2. At the same time, the filter screen 6 filters the waste, preventing it from entering the drain pipe 2 and causing blockage. By setting up the lifting device 5, when the drainage pressure is too high, the impact of the water flow on the water plate 502 can drive the rotating rod 501 to rotate. The rotating rod 501 drives the lifting rod 504 to abut against one end of the well cover 4 and lift it up, thus opening the well cover 4 to a certain size, thereby increasing drainage efficiency.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
