Description

Technical Field

[0001] This invention relates to a municipal flood control structure, belonging to the field of municipal engineering technology. Background Technology

[0002] With the acceleration of urbanization, municipal flood control is a very important project for people's livelihood.

[0003] During the rainy season, cities need a smooth drainage system to drain water from the roads. Currently, as rainwater carries mud and other debris into the sewers, the mud settles and accumulates in the sewers. Over time, this reduces the cross-sectional area of ​​the sewers and decreases their drainage capacity. Therefore, it is necessary for staff to clean the sewers regularly.

[0004] However, with existing technology, dredging is difficult and inconvenient for workers.

[0005] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a municipal flood control structure that solves the problems of high difficulty in dredging and inconvenience in operation for workers in the prior art.

[0007] The technical problem to be solved by the present invention is achieved by the following technical solution: a municipal flood control structure, including a road surface, a water pipe, and a sewer pipe, wherein a manhole cover is installed on the top of the water pipe, a settling trough is provided at the bottom of the water pipe, and a dredging component for cleaning silt in the settling trough is provided at the connection between the water pipe and the sewer pipe, the dredging component comprising:

[0008] Drive wheels are fixed to both sides of the bottom of the water pipe.

[0009] The outer wheel is rotatably connected to the outer peripheral wall of the drive wheel.

[0010] Several push plates are positioned between the two drive wheels.

[0011] The connecting rod is fixed at an eccentric point between two drive wheels and is connected to both sides of the push plate via a drive mechanism. A drive source for driving the connecting rod to rotate is provided on the outer side of one of the drive wheels.

[0012] The push plate remains vertical and has a scraper at the bottom to scrape away the sludge in the settling tank and push it into the sewer pipe.

[0013] By adopting the above technical solution, and by setting up a settling tank and sludge removal components, after rainwater carries sediment into the water pipe, the sediment settles and accumulates in the settling tank to form silt, thus preventing silt from accumulating in the sewer pipe and facilitating subsequent cleaning. The sludge removal components allow for easy cleaning by simply driving a connecting rod to rotate via a drive source. Under the drive of the connecting rod, several push plates rotate around the connecting rod. Since the push plates always rotate vertically, they push the water in the settling tank into the sewer pipe. The scraper at the bottom of the push plate scrapes up the silt deposited in the settling tank as the push plate rotates, removing the silt and allowing it to flow into the sewer pipe under the action of the water flow pushed by the push plate. This effectively improves sludge removal efficiency, reduces the difficulty of sludge removal for workers, and is very convenient to operate.

[0014] The present invention is further configured such that: the driving mechanism includes a connecting shaft and a limiting shaft; mounting plates are provided on both sides of the push plate; one end of the connecting shaft is fixed to the connecting rod and the other end is hinged to the mounting plate; one end of the limiting shaft is hinged to the outer wheel and the other end is hinged to the end of the mounting plate away from the push plate; wherein the length of the limiting shaft is less than the length of the connecting shaft.

[0015] The present invention is further configured such that: a scraper is slidably mounted on the inner circumferential wall of the drain pipe, and a drive component for driving the scraper to slide is provided on one of the outer wheels.

[0016] The present invention is further configured such that: the driving member is a driving plate rotatably connected to an outer wheel on the side away from the push plate, and the end of the driving plate away from the outer wheel is hinged to the scraper.

[0017] By adopting the above technical solution, when the push plate rotates around the connecting rod, it is only necessary to drive the connecting rod to rotate through the drive source. Under the drive of the connecting rod, several limiting shafts will drive the push plate to rotate, thereby driving the spool shaft and the outer wheel to rotate. Since one end of the limiting shaft is hinged to the mounting plate and the other end is hinged to the outer wheel, and the length of the limiting shaft is less than the length of the connecting shaft, the push plate can always remain vertical when it rotates around the connecting rod due to the limiting effect of the limiting shaft. This greatly improves the efficiency of the push plate in pushing the water flow. In addition, since a scraper is also installed in the drain pipe, when the outer wheel away from the drive source rotates, the drive plate can drive the scraper to reciprocate in the drain pipe under the action of the drive plate rotating around the drive wheel. This makes it difficult for silt to accumulate at the bottom of the drain pipe near the water pipe, further improving the efficiency of silt removal by workers and making the silt removal operation more convenient.

[0018] The present invention is further configured such that: a plurality of baffles are provided on the surface of the manhole cover, a through groove is formed between adjacent baffles, a plurality of top plates for engaging with the through groove are provided below the manhole cover, and a transmission mechanism for driving the plurality of top plates to engage with the through groove is provided below the baffles.

[0019] The present invention is further configured such that: the transmission mechanism includes a plurality of L-shaped rotating rods, the top plate is rotatably connected to the rotating rods, a connecting block is hinged to the bottom of the baffle, the end of the connecting block away from the baffle is hinged to the side wall of the top plate, and a rotating shaft is provided at the top of the rotating rod in a direction parallel to the rotating rod.

[0020] The present invention is further configured such that: the end of the rotating shaft away from the rotating rod is rotatably connected to the road surface and is provided with a synchronous pulley, and the outer sides of the plurality of synchronous pulleys are connected by a synchronous belt.

[0021] The invention is further configured such that: one of the rotating shafts extends outward from the outside of the synchronous pulley and is fixed with a handle.

[0022] The present invention is further configured such that a receiving groove for accommodating a handle is provided on one side of the road surface.

[0023] By adopting the above technical solution, several baffles are set on the surface of the manhole cover, and through grooves are formed between adjacent baffles. When rainwater carries mud, sand, and other debris into the water pipe, it will first pass through the baffles for filtration, preventing large particles of debris from entering the water pipe through the through grooves, thus further avoiding blockage of the water pipe. Furthermore, since a top plate and a transmission mechanism for driving the top plate into the through groove are installed below the manhole cover, when the through groove is blocked by debris, the transmission mechanism drives the top plate into the through groove, pushing the debris out of the manhole cover, thereby effectively preventing blockage. In addition, since the transmission mechanism includes several L-shaped rotating rods, the top plate is rotatably connected to the rotating rods, and a connecting block is hinged to the bottom of the baffle, one end of which is hinged to the side of the top plate. When the rotating shaft rotates, the rotating rods will drive the top plate to rotate around the shaft, and under the limiting effect of the connecting block, the top plate can rotate while simultaneously rotating... The rotating shaft rotates while remaining vertical, allowing it to be inserted into the through slot more easily. This facilitates the removal of debris, significantly reducing the difficulty of the task. Furthermore, because the end of the rotating shaft furthest from the rotating rod is connected to the road surface and equipped with synchronous pulleys, and several pulleys are connected by a synchronous belt, rotating the handle drives one pulley to rotate. Under the action of the synchronous belt, all pulleys rotate synchronously, causing all the rotating shafts to rotate together. This allows for easy operation of inserting all the top plates into the through slots using the handle, making the removal of debris much more convenient. The receiving slot design allows the handle to be positioned within the slot in its natural state, making it easy for workers to access and preventing pedestrians from being inconvenienced by protruding from the road surface, further enhancing operational convenience.

[0024] The beneficial effects of this invention are as follows: By setting up a settling tank and a sludge removal component, after rainwater carries sediment into the water pipe, the sediment settles and accumulates in the settling tank to form silt, thus preventing silt from accumulating in the sewer pipe and facilitating subsequent cleaning. The sludge removal component allows for easy cleaning by simply driving a connecting rod to rotate via a drive source. Under the drive of the connecting rod, several push plates rotate around the connecting rod. Since the push plates always rotate vertically, they push the water in the settling tank into the sewer pipe. The scraper at the bottom of the push plate scrapes up the silt deposited in the settling tank when the push plate rotates, removing the silt and allowing it to flow into the sewer pipe under the action of the water flow pushed by the push plate. This effectively improves the sludge removal efficiency, reduces the difficulty of sludge removal for workers, and is very convenient to operate. Attached Figure Description

[0032] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0033] like Figure 1 and Figure 2As shown, a municipal flood control structure includes a road surface 1, a water pipe 2, and a sewer pipe 3. A manhole cover 4 is installed on the top of the water pipe 2, and a settling trough 5 is provided at the bottom of the water pipe 2. A dredging assembly for cleaning silt from the settling trough 5 is installed at the connection between the water pipe 2 and the sewer pipe 3. The dredging assembly includes:

[0034] Drive wheels 6 are fixed to both sides of the bottom end of water pipe 2.

[0035] The outer wheel 7 is rotatably connected to the outer peripheral wall of the drive wheel 6.

[0036] Push plates 8, in several quantities, are positioned between the two drive wheels 6.

[0037] The connecting rod 9 is fixed at the eccentric point between the two drive wheels 6 and is connected to both sides of the push plate 8 through a drive mechanism. A drive source 10 for driving the connecting rod 9 to rotate is provided on the outer side of one drive wheel 6.

[0038] The push plate 8 is always kept vertical and has a scraper 11 at the bottom, which is used to scrape the silt in the settling tank 5 and push the silt into the drain pipe 3.

[0039] By setting up a settling tank 5 and a sludge removal component, after rainwater carries sediment into the water pipe 2, the sediment settles and accumulates in the settling tank 5 to form sludge, thus preventing sludge from accumulating in the sewer pipe 3 and facilitating subsequent cleaning. The sludge removal component allows the connecting rod 9 to rotate via the drive source 10 when sludge needs to be removed. Driven by the connecting rod 9, several push plates 8 rotate around the connecting rod 9. Since the push plates 8 always rotate vertically, they can push the water in the settling tank 5 into the sewer pipe 3. The scraper 11 at the bottom of the push plate 8 scrapes up the sludge deposited in the settling tank 5 when the push plate 8 rotates, so that the sludge is removed by the scraper 11 and flows into the sewer pipe 3 under the action of the water flow pushed by the push plate 8. This effectively improves the sludge removal efficiency, reduces the difficulty of sludge removal for workers, and is very convenient to operate.

[0040] like Figure 4 and Figure 5 As shown, the drive mechanism includes a connecting shaft 12 and a limiting shaft 13. Mounting plates 14 are provided on both sides of the push plate 8. One end of the connecting shaft 12 is fixed to the connecting rod 9, and the other end is hinged to the mounting plate 14. One end of the limiting shaft 13 is hinged to the outer wheel 7, and the other end is hinged to the end of the mounting plate 14 away from the push plate 8. The length of the limiting shaft 13 is less than the length of the connecting shaft 12.

[0041] A scraper 15 slides on the inner circumferential wall of the drain pipe 3, and a drive component for driving the scraper 15 to slide is provided on an outer wheel 7.

[0042] The driving component is a drive plate 16 rotatably connected to an outer wheel 7 on the side away from the push plate 8, and the end of the drive plate 16 away from the outer wheel 7 is hinged to the scraper 15.

[0043] This design allows the push plate 8 to rotate around the connecting rod 9 when the push plate 8 is driven by the drive source 10. Under the drive of the connecting rod 9, several limiting shafts 13 will drive the push plate 8 to rotate, thereby driving the spool shaft and the outer wheel 7 to rotate. Since one end of the limiting shaft 13 is hinged to the mounting plate 14 and the other end is hinged to the outer wheel 7, and the length of the limiting shaft 13 is less than the length of the connecting shaft 12, the limiting effect of the limiting shaft 13 ensures that the push plate 8 can always remain vertical when it rotates around the connecting rod 9, thereby greatly improving the efficiency of the push plate 8 in pushing the water flow.

[0044] Because a scraper 15 is installed inside the drain pipe 3, when the outer wheel 7, which is away from the drive source 10, rotates, the drive plate 16 can drive the scraper 15 to reciprocate inside the drain pipe 3 under the action of rotating around the drive wheel 6. This makes it difficult for silt to accumulate at the bottom of the section of the drain pipe 3 near the water pipe 2, further improving the efficiency of silt removal by the staff and making the silt removal operation more convenient.

[0045] like Figure 3 and Figure 6 As shown, the surface of the manhole cover 4 is provided with several baffles 17, and a through groove 18 is formed between adjacent baffles 17. Several top plates 19 are provided below the manhole cover 4 for engaging the through groove 18. A transmission mechanism is provided below the baffles 17 for driving the several top plates 19 to engage the through groove 18.

[0046] The transmission mechanism includes several L-shaped rotating rods 20. The top plate 19 is rotatably connected to the rotating rods 20. A connecting block 21 is hinged to the bottom of the baffle 17. The end of the connecting block 21 away from the baffle 17 is hinged to the side wall of the top plate 19. A rotating shaft 22 is provided at the top of the rotating rod 20 in a direction parallel to the rotating rod 20. The end of the rotating shaft 22 away from the rotating rod 20 is rotatably connected to the road surface 1 and is provided with a synchronous pulley 23. The outer sides of several synchronous pulleys 23 are connected by a synchronous belt 24. A rotating shaft 22 extends out of the outer side of the synchronous pulley 23 and is fixed with a handle 25.

[0047] In addition, such as Figure 1 As shown, a receiving groove 26 for accommodating the handle 25 is provided on one side of the road surface 1.

[0048] The manhole cover 4 has several baffles 17 on its surface, and a channel 18 is formed between adjacent baffles 17. When rainwater carries mud and other debris into the water pipe 2, it will first pass through the baffles 17 for filtration, so that large particles of debris cannot enter the water pipe 2 through the channel 18, thus further preventing the water pipe 2 from becoming blocked.

[0049] The manhole cover 4 is equipped with a top plate 19 and a transmission mechanism for driving the top plate 19 into the through groove 18. When the through groove 18 is blocked by debris, the transmission mechanism drives the top plate 19 into the through groove 18 to push the debris out of the manhole cover 4, thus effectively preventing the through groove 18 from becoming blocked. In addition, the transmission mechanism includes several L-shaped rotating rods 20. The top plate 19 is rotatably connected to the rotating rods 20. The bottom of the baffle 17 is hinged to a connecting block 21, one end of which is hinged to the side of the top plate 19. When the rotating shaft 22 rotates, the rotating rods 20 will drive the top plate 19 to rotate around the rotating shaft 22. Under the limitation of the connecting block 21, the top plate 19 can rotate around the rotating shaft 22 while maintaining a vertical position and being inserted into the through groove 18. This makes it easier for the top plate 19 to be inserted into the through groove 18 and push out the debris more easily, greatly reducing the difficulty of pushing out the debris.

[0050] Furthermore, since the end of the rotating shaft 22 away from the rotating rod 20 is rotatably connected to the road surface 1 and equipped with a synchronous pulley 23, and the outer sides of several synchronous pulleys 23 are connected by a synchronous belt 24, turning the handle 25 can drive one synchronous pulley 23 to rotate. Under the action of the synchronous belt 24, all synchronous pulleys 23 rotate synchronously, thereby driving all rotating shafts 22 to rotate together. This enables the operation of inserting all top plates 19 into the through slots 18 by using the handle 25, making it more convenient to push out debris from the top plates 19.

[0051] The inclusion of the receiving groove 26 allows the handle 25 to be located within the receiving groove 26 in its natural state, making it convenient for staff to pick up and avoiding the inconvenience to pedestrians caused by protruding from the road surface 1, thus making operation more convenient.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention.
