Description

Technical Field

[0001] This invention relates to the field of high-efficiency drainage technology, specifically a high-efficiency drainage device for urban flood control. Background Technology

[0002] Because the drainage channels in the sewer partitions of urban roads are narrowly spaced and can change their spacing, when there is a lot of standing water on urban roads, some plastic waste and dead leaves on the road surface will flow into the sewers with the water, while other plastic waste and dead leaves will block the drainage channels in the partitions. This prevents the standing water on urban roads from flowing into the sewers quickly, which can easily lead to water accumulation on urban roads and cause flooding.

[0003] Therefore, we propose a high-efficiency drainage device for urban flood control. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency drainage device for urban flood control, which solves the problems mentioned in the background section above:

[0005] The connecting rod deflects under the gravity of the slag collection frame, causing the sliding sleeve to move horizontally within the cross frame. Under the action of the gears, when the two toothed plates move horizontally away from each other within the sliding groove, the two guide rods also move horizontally away from each other simultaneously. The movement of the guide rods causes the pull rod to deflect, which in turn causes the grid strips to deflect, thereby maximizing the opening of the grid frame's inlet. This allows larger pieces of garbage to flow into the slag collection frame, preventing them from clogging the grid frame's inlet and affecting the drainage of road surface water. This accelerates the flow of road surface water, allowing it to flow more quickly into the water chamber and through the pipes. Thus, this invention achieves efficient drainage of road surface water, solving the problem that existing urban road sewer openings cannot be adjusted automatically, causing garbage to clog the sewer openings and preventing the rapid drainage of road surface water.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A high-efficiency drainage device for urban flood control includes a road surface, a water passage chamber at the bottom of the road surface, a drainage trough and an inlet / outlet trough at the top of the road surface, a cover plate installed on the top of the inlet / outlet trough, and a frame fixedly connected to the inner walls of both the drainage trough and the inlet / outlet trough. A grid frame is installed on the top of the drainage trough, and an adjustment component is installed inside the drainage trough. The adjustment component includes a grid bar one, a grid bar two, a slide groove one, a slide groove two, a gear, a toothed plate one, a toothed plate two, a guide rod, a tie rod, a crossbar, a connecting rod, and a bracket one. The inner wall of the grid frame is fixed with grid bar one by spot welding, and one end of grid bar one is rotatably connected to grid bar two.

[0008] The inner wall of the grid frame is provided with two sliding grooves on both sides. Gears are movably connected to the inner wall of the grid frame through bearings. The gears are located between the two sliding grooves. A toothed plate is slidably connected inside the first sliding groove, and a toothed plate is slidably connected inside the second sliding groove. Both toothed plates mesh with the gears. A guide rod is fixed to the adjacent side of the toothed plate by spot welding. A pull rod is rotatably connected to the bottom of the guide rod. A slot is provided at the top of the second grid bar. One end of the pull rod is rotatably connected to the second grid bar, and the pull rod cooperates with the slot. A crossbar is fixedly connected between adjacent second grid bars. A bracket is fixedly connected to the bottom of the second toothed plate. A connecting rod is rotatably connected inside the bracket, and the middle of the two connecting rods is movably connected by bearings.

[0009] Furthermore, the adjustment assembly also includes a slag collection frame, a crossbeam, a sliding sleeve one, a support two, a cross plate, a handrail, a sliding sleeve two, and a connecting rod. The slag collection frame is installed in the water passage chamber. A crossbeam is symmetrically fixed to the top of the slag collection frame. A long rod is fixedly connected to the inner side of the crossbeam, and a sliding sleeve one is slidably connected inside the long rod. A compression spring one is sleeved on the outer side of the long rod, and the two ends of the compression spring one are fixedly connected to the sliding sleeve one and the crossbeam, respectively. A support two is fixed to the top of the sliding sleeve one by spot welding. The end of the connecting rod away from the support one is rotatably connected to the support two.

[0010] Furthermore, horizontal plates are fixedly connected to both sides of the slag collection frame, and bracket three is fixedly connected to the bottom of the horizontal plates. Support rods are symmetrically fixed to the inner wall of the water passage chamber. Sliding sleeve two and compression spring two are sleeved on the outer side of the support rods. Support four is fixedly connected to the top of the sliding sleeve two. An abutment rod is rotatably connected between support three and support four.

[0011] Furthermore, the water passage chamber is connected to a pipe, and a material collection assembly is installed inside the water passage chamber. The material collection assembly includes a frame, with several baffles fixedly connected to the top of the frame, several bolt holes on the outside of the frame, and insertion holes at the four corners of the top of the frame. Insertion blocks are fixedly connected to the four corners of the top of the slag collection frame, and the insertion blocks cooperate with the insertion holes. Several hooks are fixedly connected to the inside of the frame, and a collection net is installed inside the slag collection frame, with the collection net connected to the hooks. Filter holes are provided on the outside of both the slag collection frame and the collection net.

[0012] Furthermore, a ladder is fixedly connected inside the water passage chamber, and the ladder is located below the inlet / outlet trough. A diversion trough frame is detachably installed inside the water passage chamber, and the diversion trough frame is located above the slag collection frame.

[0013] This invention also proposes a method for operating a high-efficiency drainage device for urban flood control, comprising the following steps:

[0014] Step 1: When water accumulates on the road surface, the water will flow from the drain into the water chamber and then flow away through the pipe. When there is too much water flowing on the road surface, the water will carry small pieces of garbage into the drain. Under the guidance of the diversion trough frame, the water and garbage will enter the collection net in the slag collection frame. Garbage of a certain weight and silt left on the road surface will settle at the bottom of the collection net and block the filter holes near the bottom of the collection net and the slag collection frame.

[0015] Step Two: Because the drainage holes at the bottom of the slag collection frame and the collection net are blocked by garbage and silt, the water flowing in from the road surface gradually increases inside the slag collection frame. As the water inside the frame increases, the weight of the slag collection frame also increases. This increased weight gradually pulls the connecting rod, causing it to deflect. This causes the sliding sleeve one to slide within the crossbeam. The deflection of the connecting rod then drives the bracket one and the toothed plate two connected to its top to move horizontally. The horizontal movement of the toothed plate two drives the gear to rotate synchronously. The rotation of the gear drives the toothed plate one and the guide rod to move horizontally. The horizontal movement of the guide rod drives the pull rod connected to its bottom to rotate. As the guide rod moves horizontally... The pull rod will cause the second grid bar to rotate at one end of the first grid bar until the collection frame stops sinking. At this time, the second grid bar inside the grid frame is deflected to the maximum angle, which makes the water inlet trough at the top of the grid frame in the maximum state. This allows larger garbage to pass through the grid frame smoothly and be sucked into the collection frame for collection. This avoids the problem that the existing drainage ditch is easily blocked by small garbage on the road surface, which would cause water to accumulate on the road surface and cause flooding. The water overflowing from the top of the collection frame flows to the next place through the pipe. At the same time, the baffle at the top of the frame will block plastic garbage or weeds and leaves inside the collection frame, thus preventing these garbage from overflowing into the pipe.

[0016] Step 3: After the water on the road surface is successfully drained from the pipes, relevant personnel open the cover plate and enter the water circulation chamber using a ladder. They then connect the collection net to the rope using ropes and other devices, and use the other end of the rope to pull the collection net and garbage out to the road surface. After emptying the garbage from the collection net, the collection net is fixed inside the enclosure. At the same time, sanitation workers use a ladder to enter the water circulation chamber to clean the remaining garbage and silt in the collection frame, ensuring that the filter holes of the collection frame remain unobstructed. Finally, the enclosure is lowered and the insertion holes and insertion blocks are connected. Since the garbage and water in the collection frame have been cleaned, the collection frame is restored to its initial weight and, under the action of multiple compression springs, rises back to its initial position. Simultaneously, the grid bars gradually return to their initial positions as the collection frame rises, thereby reducing the area of ​​the water inlet channel of the grid frame. This allows it to drain water and block garbage even when there is not a large amount of standing water in the city, while also preventing people from stepping into the hole and endangering their personal safety.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention is applied to situations where heavy rainfall occurs in cities. Small-sized debris flows rapidly into the collection net through the gaps in the grid bars two, along with accumulated water. The small-sized debris and silt from city roads clog the collection net and the filter holes at the bottom of the collection frame, causing the collection frame to passively begin storing water. This passively increases the weight of the collection frame, causing it to move downwards. The connecting rod deflects under the weight of the collection frame, causing the sliding sleeve one to move horizontally within the crossbeam. Simultaneously, the bracket one drives the top toothed plate two to slide within the sliding groove two, in the gear... Under the action of the two toothed plates, when the two toothed plates move horizontally away from each other in the sliding groove, the two guide rods also move horizontally away from each other at the same time. The movement of the guide rods causes the pull rod to deflect, which in turn causes the grid strips to deflect, thereby realizing that the water inlet of the grid frame is opened to the maximum extent, so that the larger garbage flows into the slag collection frame, preventing it from blocking the water inlet of the grid frame and affecting the drainage of road surface water. This speeds up the flow of road surface water, allowing it to flow more quickly into the water passage chamber and flow away through the pipe. Thus, the present invention achieves the purpose of efficient drainage of road surface water.

[0019] 2. The top of the slag collection frame is fixedly connected with a plug-in block, and the frame has plug-in holes that connect with the plug-in block. At the same time, a considerable number of baffles are installed on the top of the frame, and there are gaps between the baffles. This helps to block the garbage floating in the water inside the slag collection frame, allowing the water overflowing from the top of the slag collection frame to flow out through the gaps between the baffles. Meanwhile, the floating garbage is blocked inside the slag collection frame, effectively preventing the garbage from flowing into the pipe with the water and causing blockage.

[0020] 3. During the process of gradually decreasing or stopping urban rainfall, the filter holes of the slag collection frame can still play a role in drainage, thereby gradually reducing the weight of the slag collection frame. When the water in the slag collection frame is drained and only a certain amount of garbage is stored, the slag collection frame gradually rises under the combined action of the abutment rod, compression spring two, and compression spring one. The gradual rise of the slag collection frame causes the two connecting rods to deflect, which in turn drives the two toothed plates two to move away from each other. The two toothed plates one move closer to each other under the action of gears. The guide rod moves the grid strip two to the initial position through the pull rod under the movement of the toothed plates one. Moreover, this invention is installed in the green belt, which can effectively prevent people or animals from stepping into the gap. The collection net of this invention is detachable, which allows emergency repair personnel to quickly and conveniently remove the garbage collected by the slag collection frame.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figure 1-9 As shown, the present invention provides a technical solution:

[0034] Example 1:

[0035] In some cities, drainage systems are installed within the green belts along the roads. However, due to the frequent accumulation of garbage and gravel on urban roads, and the narrow spacing between the drainage channels in the sewer slabs, when roads are flooded, plastic debris and fallen leaves can flow with the water into these channels, clogging them and preventing the water from flowing quickly into the sewers. Furthermore, the complex and extensive urban drainage network makes it impossible to manually check for blockages in every sewer opening in a short time after a large amount of water has accumulated. Additionally, the murky water mixed with dust makes it difficult for repair personnel to visually locate and remove the blockages. To address this issue, the following measures are proposed:

[0036] When there is a normal amount of standing water on city roads, the water will drain away through the corresponding sewer outlets:

[0037] When a sudden, heavy downpour occurs on city roads, water quickly accumulates and flows down to the drainage trough 3. Road debris also flows down to the drainage trough 3 along with the water. As the debris accumulates in the drainage trough 3, smaller pieces of debris are carried by the water through the gaps in the grid frame 7 into the water passage chamber 2. The water passage chamber 2 is equipped with a diversion trough frame 8. It should be noted that the bottom discharge port of the diversion trough frame 8 is smaller in diameter than the slag collection frame 912. This allows the accumulated water and smaller debris flowing from the gaps in the grid frame 7 to accurately flow along the surface of the diversion trough frame 8 into the slag collection frame 912. The slag collection frame 912 is equipped with a collection net, which collects the accumulated water and smaller debris. After entering the collection net, the accumulated water will gradually flow out from the filter holes of the collection net and the slag collection frame 912, causing garbage and silt to clog the filter net and the filter holes near the bottom of the slag collection frame 912. At the same time, the mixture of water and garbage on the road surface 1 will continuously flow into the collection net through the diversion trough frame 8. Meanwhile, because the filter holes at the bottom of the collection net and the slag collection frame 912 are blocked, the water and garbage inside the slag collection frame 912 will gradually increase, causing the mass of the slag collection frame 912 to gradually increase until it reaches a critical point under its own weight. At this point, the slag collection frame 912 will begin to move downward. A crossbeam 913 is fixedly connected to the top of the slag collection frame 912, and a sliding sleeve 914 is slidably connected inside the crossbeam 913. The top of the sliding sleeve 914 is fixedly connected to... A second support 915 is connected, and a connecting rod 911 is rotatably connected between the second support 915 and the first support 920. A toothed plate 907 is fixedly connected to the top of the first support 920. During the downward movement of the slag collection frame 912, the connecting rod 911 deflects under the gravity of the slag collection frame 912, thereby causing the sliding sleeve 914 to move horizontally within the cross frame 913. At the same time, the first support 920 drives the toothed plate 907 at the top to slide within the sliding groove 904. A gear 905 is movably connected to the inner wall of the grid frame 7 through a bearing. Both the toothed plate 906 and the toothed plate 907 are meshed with the gear 905. Therefore, when the two toothed plates 907 approach each other horizontally, under the action of the gear 905, the two toothed plates 906 slide within the sliding groove. Within the groove 903, the two toothed plates 906 are horizontally separated from each other. A guide rod 908 is fixedly connected between the toothed plates 906. Several grid strips 901 are fixedly connected to the inner wall of the grid frame 7. One end of the grid strip 901 is rotatably connected to a grid strip 902. A tie rod 909 is rotatably connected to the top of the grid strip 902. One end of the tie rod 909 is rotatably connected to the guide rod 908. A crossbar 910 is fixedly connected between adjacent grid strips 902. When the two toothed plates 906 are horizontally separated from each other within the groove 903, the two guide rods 908 are also horizontally separated from each other at the same time. The movement of the guide rod 908 causes the tie rod 909 to deflect, which in turn causes the grid strip 902 to deflect, thus expanding the water inlet of the grid frame 7.

[0038] When the slag collection frame 912 of the present invention is filled with water and garbage and is at a relatively constant mass, the slag collection frame 912 stops sinking. At this time, the pull rod 909 stops rotating, and the grid bar 902 is opened to the maximum extent, thereby realizing that the water inlet of the grid frame 7 is opened to the maximum extent, so that the larger garbage flows into the slag collection frame 912, preventing it from blocking the water inlet of the grid frame 7 and affecting the drainage of water on the road surface 1. This speeds up the flow of water on the road surface 1, allowing it to flow more quickly into the water chamber 2 and flow away through the pipe 10. Thus, the present invention achieves the purpose of efficient drainage of water on the road surface 1.

[0039] The top of the slag collection frame 912 is fixedly connected to the plug-in block 113, and the frame 111 is provided with a plug-in hole 112. The plug-in hole 112 and the plug-in block 113 are connected. At the same time, a considerable number of baffles 13 are installed on the top of the frame 111, and a certain gap is left between the baffles 13. This blocks the garbage floating in the water inside the slag collection frame 912, allowing the water overflowing from the top of the slag collection frame 912 to flow out through the gaps in the baffles 13. Meanwhile, the floating garbage is blocked inside the slag collection frame 912, effectively preventing the garbage from flowing into the pipe 10 with the water and causing blockage.

[0040] Example 3:

[0041] After the rainfall stops, the water on the road surface 1 will gradually flow into the water passage chamber 2 until the water on the road surface 1 is completely drained. Nowadays, when urban flooding occurs, emergency repair personnel are arranged in a short time to thoroughly check the specific situation of the flooded or submerged sewers. Therefore, when the grid strip 902 set in this invention is fully opened under the gravity of the slag collection frame 912, there is no need to worry that the water passage hole of this invention will always be in the maximum open state, and the water filter hole of the slag collection frame 912 can still play the role of drainage, thereby gradually reducing the weight of the slag collection frame 912.

[0042] A horizontal plate 916 is fixedly connected to both sides of the slag collection frame 912. A bracket three is fixedly connected to the bottom of the horizontal plate 916. A support rod 917 is symmetrically fixed to the inner wall of the water passage chamber 2. A sliding sleeve two 918 and a compression spring two are sleeved on the outer side of the support rod 917. A bracket four is fixedly connected to the top of the sliding sleeve two 918. An abutment rod 919 is rotatably connected between the bracket three and the bracket four. When the accumulated water in the slag collection frame 912 is discharged and only a certain amount of garbage is stored, the slag collection frame 912 gradually rises under the combined action of the abutment rod 919, the compression spring two and the compression spring one. The gradual rise of the slag collection frame 912 causes the two connecting rods 911 to deflect, and at the same time, it will drive the two toothed plates two 907 to move away from each other. The two toothed plates one 906 move closer to each other under the action of the gear 905. The guide rod 908 included in the adjustment component 9 moves the grid bar two 902 to the initial position through the pull rod 909 under the movement of the toothed plates one 906.

[0043] The repair crew determined that the slag collection frame 912 contained a certain amount of garbage because the grid strip 902 was not completely level. Therefore, the crew removed the cover plate 5 from the frame 6 installed on the inner wall of the inlet / outlet trough 4 and entered the water passage chamber 2 via the ladder 12. Another crew member threw a rope from the drain trough 3. The crew member inside the water passage chamber 2 then removed the collection net from the hook 114 and tied the rope to the end of the collection net. It should be noted that the diversion trough frame 8 is detachable and can be divided into two halves, facilitating the collection net to collect garbage along with the debris. The garbage passes through, and then the repair personnel on the road surface 1 work together to pull the garbage out of the drain trough 3 and clean the garbage in the collection net. At the same time, they also clean the silt in the sludge collection frame 912, thereby restoring the blocked water filter holes to normal use. After the collection net is cleaned, it is reconnected to the hook 114 included in the material collection component 11. Finally, the enclosure 111 and the sludge collection frame 912 are assembled. Through the above description, the purpose of efficiently draining the water accumulated on the road surface 1 is achieved, and the purpose of collecting garbage on the road surface 1 is also achieved to prevent blockage of the pipe 10.

Clearly, many modifications and variations can be made based on the content of this specification.

Insertion holes (112) are opened at the four corners of the top of the frame (111). Insertion blocks (113) are fixedly connected to the four corners of the top of the slag collection frame (912). The insertion blocks (113) cooperate with the insertion holes (112). Several hooks (114) are fixedly connected to the inside of the frame (111). A collection net is installed inside the slag collection frame (912), and the collection net is connected to the hooks (114). Filter holes are opened on the outside of both the slag collection frame (912) and the collection net.

3. The high-efficiency drainage equipment for urban flood control according to claim 2, characterized in that, The water passage chamber (2) is fixedly connected to a ladder (12), and the ladder (12) is located below the inlet / outlet trough (4). The water passage chamber (2) is detachably installed with a diversion trough frame (8), and the diversion trough frame (8) is located above the slag collection frame (912).

4. A method for operating a high-efficiency drainage device for urban flood control as described in claim 3, characterized in that, Includes the following steps: Step 1: When water accumulates on the road surface (1), the water will flow from the drain (3) into the water chamber (2) and then flow away through the pipe (10). When too much water flows through the road surface (1), the water will carry small garbage into the drain (3). The water and garbage will enter the collection net in the slag collection frame (912) under the guidance of the diversion trough frame (8). Garbage with a certain mass and silt left on the road surface (1) will settle at the bottom of the collection net and block the filter holes near the bottom of the collection net and the slag collection frame (912). Step 2: Because the filter holes at the bottom of the slag collection frame (912) and the collection net are blocked by garbage and silt, the water flowing in from the road surface (1) will gradually increase inside the slag collection frame (912). As the water stored inside the slag collection frame (912) increases, the mass of the slag collection frame (912) will also increase. The increase in the mass of the slag collection frame (912) will gradually pull the connecting rod (911) to deflect, which will cause the first sliding sleeve (914) to slide in the cross frame (913). The deflection of the connecting rod (911) will then drive the first bracket (920) and the second toothed plate (907) connected to its top to move horizontally. The horizontal movement of the second toothed plate (907) will drive the gear (905) to rotate synchronously. The rotation of the gear (905) will drive the first toothed plate (906) and the guide rod (908) to move horizontally. The horizontal movement of the guide rod (908) will drive the pull rod (909) connected to its bottom to rotate. When the lever (908) moves horizontally, the pull rod (909) will cause the second grid bar (902) to rotate at one end of the first grid bar (901) until the collection frame (912) stops sinking. At this time, the second grid bar (902) inside the grid frame (7) is deflected to the maximum angle, so that the water inlet trough at the top of the grid frame (7) is in the maximum state, so that larger garbage can pass through the grid frame (7) smoothly and be sucked into the collection frame (912) for collection. This avoids the problem that the existing drainage trough is easily blocked by small garbage on the road surface (1), which causes water to accumulate on the road surface (1) and cannot pass through the drainage trough to form floods. The water overflowing from the top of the collection frame (912) flows to the next place through the pipe (10). At the same time, the baffle (13) at the top of the frame (111) blocks the plastic garbage or weeds and leaves inside the collection frame (912), thereby preventing these garbage from overflowing into the pipe (10). Step 3: After the water on the road surface (1) is successfully drained from the pipe (10), relevant personnel open the cover plate (5) and enter the water passage chamber (2) using the ladder (12). They then connect the collection net to the rope using ropes and other devices, and pull the collection net and garbage out to the road surface (1) using the other end of the rope. After emptying the garbage from the collection net, the collection net is fixed inside the enclosure (111). At the same time, cleaning personnel enter the water passage chamber (2) using the ladder (12) to clean the remaining garbage and silt in the sludge collection frame (912), ensuring that the filter holes of the sludge collection frame (912) remain unobstructed. Finally, the frame (111) is lowered and the insertion hole (112) and the insertion block (113) are connected. After the garbage and water in the slag collection frame (912) are cleaned up, the slag collection frame (912) is restored to its initial weight and rises back to its initial position under the action of multiple compression springs. At the same time, the grid strip (902) gradually returns to its initial position as the slag collection frame (912) rises, thereby reducing the area of ​​the water inlet of the grid frame (7), so that it can drain water and block garbage in the absence of a large amount of water accumulation in the city, and at the same time, it can also prevent people from stepping into the air and endangering their personal safety.
