Description

Technical Field

[0001] The present invention relates to an anti-blocking water inlet of a drainage system for municipal engineering and its usage method, belonging to the field of municipal drainage engineering. Background Art

[0002] In municipal engineering, the urban drainage system is particularly important, especially the drainage outlets set on both sides of the road. When discharging rainwater, during heavy rain or rainstorm weather, the rainwater on the ground will converge into a flowing stream. The rainwater will wash away the garbage on the ground and flow out at the drainage outlet, resulting in the garbage being blocked at the grid position of the drainage outlet. Especially some garbage such as plastic bags and packaging bags will block most of the drainage outlet, affecting the drainage volume of the drainage outlet. As a result, the accumulated water on the road cannot be discharged in time, affecting the passage of citizens and vehicles. Therefore, it is necessary to improve it. Summary of the Invention

[0003] The purpose of the present invention is to solve the above problems in the background art, and provide an anti-blocking water inlet of a drainage system for municipal engineering and its usage method.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A usage method of an anti-blocking water inlet of a drainage system for municipal engineering, the usage method includes the following steps:

[0007] Step 1: When the water inflow volume per unit time of the drainage outlet is less than the drainage volume per unit time of Filter Plate I and Filter Plate II, rainwater passes through the grid, Filter Plate I, and Filter Plate II and is discharged into the drainage pipeline.

[0008] Step 2: When the water inflow volume per unit time of the drainage outlet is greater than the drainage volume per unit time of Filter Plate I and Filter Plate II, rainwater accumulates at the upper ends of Filter Plate I and Filter Plate II, the volume of rainwater increases, driving the upward movement of Floating Block I, Floating Block II, and Floating Block III to prevent the grid from being blocked.

[0009] Compared with the prior art, the beneficial effect of the present invention is: The present invention can not only effectively prevent garbage from blocking the grid and affecting the drainage volume of the drainage outlet during heavy rain or rainstorm weather, but also can wind plastic bag-like garbage around the round rod or push away packaging bag-like garbage through the cleaning device to avoid blocking the grid.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0021] Detailed Embodiment 1: As Figures 1-10As shown in the figure, this embodiment describes an inlet of an anti-blocking drainage system for municipal engineering, including a grate 1; the grate 1 includes an outer frame 11; the outer frame 11 is fixedly connected to the top of the drainage port 4, and a slide bar 17 is fixedly connected to the inner wall of the outer frame 11. The outer frame 11 is slidably matched with a rectangular cylinder 12. A chute for slidably matching with the slide bar 17 is provided on the side of the rectangular cylinder 12, and a plurality of filter holes 14 are provided on the rectangular cylinder 12; a floating block I 16 is fixedly connected to the inner wall of the rectangular cylinder 12 through a connecting rod 15, and a plurality of fixing rods 13 are also fixedly connected to the top end of the inner wall of the rectangular cylinder 12. After the drainage port 4 is filled with rainwater 5, the rectangular cylinder 12 is driven to move upward by the buoyancy of the floating block I 16, so that the sum of the water inflow at the top and side of the rectangular cylinder 12 is greater than the drainage volume of the drainage port 4, so that even if part of the side or top of the rectangular cylinder 12 is blocked, it will not affect the drainage volume of the drainage port 4.

[0022] Both the rectangular cylinder 12 and the fixing rod 13 are made of materials with a density less than that of cast iron.

[0023] It also includes a control device 3; the control device 3 includes a filter plate I 31; the filter plate I 31 is fixedly connected to the inner wall of the drainage port 4, and a through hole 33 is provided in the center of the filter plate I 31; a filter barrel 35 slidably matched with the through hole 33 is provided in the through hole 33. The top end of the filter barrel 35 is fixedly connected with a filter plate II 32, and a limiting block 36 is fixedly connected to the bottom outside of the filter barrel 35; a floating block II 34 is fixedly connected to the upper end of the filter plate II 32. When the rainwater 5 in the drainage port 4 accumulates and the liquid level continuously rises, the floating block II 34 drives the filter plate II 32 to move upward, so that the filter barrel 35 moves to the upper end of the filter plate I 31, increasing the drainage volume of the control device 3. At the same time, when it is sunny, the filter barrel 35 will move to the lower end of the filter plate I 31, which can effectively prevent the filter barrel 35 from being blocked and ensure the drainage volume of the control device 3.

[0024] A plurality of vertical through holes are also provided on the filter plate I 31, and a cleaning device 2 is fixedly connected in the through holes.

[0025] The cleaning device 2 includes a fixed cylinder 22; the fixed cylinder 22 is fixedly connected to the inner wall of the through hole on the filter plate I 31, a connecting rod 29 is fixedly connected to the inner wall of the fixed cylinder 22, and the other end of the connecting rod 29 is fixedly connected to a connecting ring 210; the connecting ring 210 is slidably matched with a round rod 25; a floating block III 21 is fixedly connected to the outside of the round rod 25, and the floating block III 21 is located above the fixed cylinder 22; a limiting rod 27 is fixedly connected to the bottom side of the round rod 25. As the liquid level rises, the floating block III 21 can drive the round rod 25 to move upward, and the floating block III 21 is always located below the floating block I 16. Therefore, when the liquid level drops, the floating block III 21 will drop later than the floating block I 16. Therefore, part of the time the round rod 25 is located above the fixing rod 13, pushing the garbage above the fixing rod 13 away.

[0026] A plurality of conical bumps 28 are fixedly connected to the top side of the round rod 25; a plurality of obliquely arranged transmission plates 26 are arranged on the outer circumferential surface of the round rod 25, and the transmission plates 26 are located below the fixed cylinder 22. The rainwater 5 flowing through the fixed cylinder 22 pushes the transmission plates 26 to move, thereby driving the round rod 25 to rotate, winding up plastic bag-like garbage, so as to prevent the garbage from being unfolded by the water flow impact and covering the upper end of the rectangular cylinder 12, causing a large-area blockage and affecting the water inflow volume.

[0027] When the float III 21 drives the round rod 25 to move upward under the buoyancy force, the transmission plate 26 moves into the fixed cylinder 22 along with the round rod 25.

[0028] The bottom side of the fixed cylinder 22 is connected with a rotating ring 23 through a bearing, and a plurality of notches 24 which are slidably matched with the limiting rods 27 are arranged at the bottom of the rotating ring 23. After the float III 21 moves upward, the limiting rod 27 moves into the notch 24. After the water flow impacts the transmission plate 26, the round rod 25 rotates. The limiting rod 27 is located in the notch 24 of the rotating ring 23, and the rotating ring 23 is connected with the fixed cylinder 22 through a bearing, which can effectively reduce the friction force.

[0029] Each cleaning device 2 is located in the gap between two adjacent fixing rods 13.

[0030] A using method of the water inlet of a municipal engineering anti-blocking drainage system, the using method comprising the following steps:

[0031] Step 1: When the water inflow volume per unit time of the drain port 4 is less than the drainage volume per unit time of the filter plate I 31 and the filter plate II 32, the rainwater 5 passes through the grate 1, the filter plate I 31, and the filter plate II 32 and is discharged into the drainage pipe.

[0032] Step 2: When the water inflow volume per unit time of the drain port 4 is greater than the drainage volume per unit time of the filter plate I 31 and the filter plate II 32, the rainwater 5 accumulates at the upper ends of the filter plate I 31 and the filter plate II 32. The volume of the rainwater 5 increases, driving the float I 16, the float II 34, and the float III 21 to move upward to prevent the grate 1 from being blocked.

[0033] The working principle of the present invention is: When using this device in weather where the water inflow volume of the drain port 4 is less than the maximum drainage volume of the control device 3 (i.e., light rain weather), when the water inflow volume per unit time of the drain port 4 is less than the drainage volume per unit time of the filter plate I 31 and the filter plate II 32, the rainwater 5 passes through the grate 1, the filter plate I 31, and the filter plate II 32 and is discharged into the drainage pipe, as shown in Figure 1 the state shown;

[0034] When the amount of water entering the drain outlet 4 per unit time is greater than the amount of water discharged by the filter plates I 31 and II 32 per unit time, rainwater 5 flows into the drain outlet 4 through the gaps between the fixing rods 13. Since the amount of water entering the drain outlet 4 per unit time is greater than the amount of water discharged by the filter plates I 31 and II 32 per unit time, rainwater 5 accumulates on the upper ends of the filter plates I 31 and II 32, causing the liquid level to rise continuously. During the rising liquid level, the floating block II 34 is driven upward, and the floating block II 34 then drives the filter barrel 35 and the filter plates II 32 upward, allowing the rainwater 5 to be discharged through the filter barrel 35, thereby increasing the drainage volume and preventing rainwater from accumulating in the drain outlet 4.

[0035] When the device is used in weather conditions where the amount of water entering the drain outlet 4 is greater than the maximum discharge capacity of the control device 3 (i.e., heavy rain or rainstorm weather), a large amount of rainwater 5 accumulates on the road and converges into a stream. After the float block II 34 drives the filter barrel 35 to move upward, the amount of water entering the drain outlet 4 is still greater than the discharge capacity of the filter plate I 31, the filter plate II 32, and the filter barrel 35, causing the rainwater 5 in the drain outlet 4 to continue to accumulate and the liquid level to rise. The rising liquid level drives the float block I 16 to move upward, and then drives the rectangular tube 12 upward through the connecting rod 15. The rectangular tube 12 is moved so that the height thereof is higher than the road surface, so that when the garbage flowing with the water flow blocks part of the upper end or part of the side of the rectangular tube 12, it does not affect the rainwater 5 on the road from flowing into the drain outlet 4. In the process of the liquid level rising in the drain outlet 4, the float block III 21 also moves upward, and the float block III 21 drives the round rod 25 to move upward, thereby driving the transmission plate 26 to move into the fixed tube 22, and the limit rod 27 is embedded in the notch 24. After the round rod 25 moves upward, the height of its highest point is higher than the road surface, that is, Figure 9 Status shown;

[0036] When the upper end or side of the rectangular tube 12 is blocked by garbage, so that the water inlet is less than the drainage capacity of the filter plate I 31, the filter plate II 32, and the filter barrel 35, the liquid level in the drain port 4 continues to drop. Since the float I 16 is located at the highest point, during the process of the liquid level dropping, the float I 16 first moves downward with the liquid level, causing the rectangular tube 12 to move downward under the action of gravity, and then pushes the garbage on the side of the rectangular tube 12 away through the outer frame 11, so that it is separated from the rectangular tube 12. When the liquid level drops to Figure 10 At the height shown, since the floating block III 21 is still at the high point due to the influence of buoyancy, the height of the round rod 25 is now higher than the height of the fixed rod 13, and the round rod 25 is located in the gap between two adjacent fixed rods 13. Therefore, in the process of the rectangular tube 12 moving downward, the round rod 25 will push away the garbage above the rectangular tube 12 to avoid the rectangular tube 12 being blocked by the garbage. After pushing the garbage away, the garbage will be washed away by the water flow on the road after leaving the rectangular tube 12. The water inflow at the upper end of the rectangular tube 12 is greater than the drainage capacity of the filter plate I 31, the filter plate II 32, and the filter barrel 35, so that the liquid level in the drain port 4 rises again, thereby driving the rectangular tube 12 to move upward and reach the height shown in FIG.Figure 9 The state shown

[0037] When the garbage blocked by the upper end of the rectangular cylinder 12 is a plastic bag or a packaging bag, due to the blockage of the plastic bag or the packaging bag, the water inflow of the rectangular cylinder 12 is reduced and less than the drainage volume, causing the liquid level to continuously drop. In the above-mentioned manner, the rectangular cylinder 12 moves downward. The height of the round rod 25 is higher than the height of the fixed rod 13, pushing away the not easily curled packaging bag, making it flow with the water flow and separate from the rectangular cylinder 12. The plastic bag-like garbage will lean against the top and side of the round rod 25 under the impact of the water flow. During the process of the liquid level in the drain port 4 dropping, part of the rainwater 5 will flow downward through the fixed cylinder 22. After the round rod 25 moves upward, the transmission plate 26 is located in the fixed cylinder 22, and the downward flowing rainwater 5 will continuously push the obliquely arranged transmission plate 26 to rotate. The transmission plate 26 drives the round rod 25 to rotate, and a plurality of conical protrusions 28 are provided on the top side of the round rod 25. During the rotation of the round rod 25, the conical protrusions 28 will drive the plastic bag-like garbage leaning against the top and side of the round rod 28, so that the plastic bag-like garbage is wound around the side of the round rod 25, reducing the unfolded area of the plastic bag-like garbage after being impacted by the water flow, and further reducing the blockage of the upper end of the rectangular cylinder 12. After the plastic bag or packaging bag-like garbage is removed, the water inflow at the upper end of the rectangular cylinder 12 is greater than the drainage volume of the filter plate I 31, the filter plate II 32, and the filter barrel 35, causing the liquid level height in the drain port 4 to rise again, thereby driving the rectangular cylinder 12 to move upward again to reach the state as shown in Figure 9 The state shown
