[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Specific implementation method 1: Figure 1-10As shown, this embodiment describes a water inlet of a municipal engineering anti-blocking drainage system, including a grate 1; the grate 1 includes an outer frame 11; the outer frame 11 is fixedly connected to the top of the drain outlet 4, 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 tube 12, the side of the rectangular tube 12 is provided with a slide groove slidably matched with the slide bar 17, and the rectangular tube 12 is provided with a plurality of filter holes 14; a floating block Ⅰ 16 is fixedly connected to the inner wall of the rectangular tube 12 through a connecting rod 15, and a plurality of fixed rods 13 are also fixedly connected to the top of the inner wall of the rectangular tube 12. After the drain outlet 4 is filled with rainwater 5, the buoyancy of the floating block Ⅰ 16 drives the rectangular tube 12 to move upward, so that the sum of the water inflow at the top and side of the rectangular tube 12 is greater than the drainage volume of the drain outlet 4, so that even if the side or top part of the rectangular tube 12 is blocked, it will not affect the drainage volume of the drain outlet 4.

[0022] The rectangular tube 12 and the fixing rod 13 are both made of a material with a density lower than that of cast iron.

[0023] The control device 3 is also included; the control device 3 includes a filter plate I 31; the filter plate I 31 is fixedly connected to the inner wall of the drain outlet 4, and a through hole 33 is provided in the center of the filter plate I 31; a filter barrel 35 is provided in the through hole 33 to be slidably matched therewith, a filter plate II 32 is fixedly connected to the top of the filter barrel 35, and a limit block 36 is fixedly connected to the outer bottom of the filter barrel 35; a floating block II 34 is fixedly connected to the upper end of the filter plate II 32. When rainwater 5 accumulates in the drain outlet 4 and the liquid level continues to rise, 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, and at the same time, the filter barrel 35 will move to the lower end of the filter plate I 31 on sunny days, which can effectively prevent the filter barrel 35 from being blocked and ensure the drainage volume of the control device 3.

[0024] The filter plate Ⅰ31 is also provided with a plurality of vertical through holes, 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 perforation on the filter plate Ⅰ31, a connecting rod 29 is fixedly connected to the inner wall of the fixed cylinder 22, and a connecting ring 210 is fixedly connected to the other end of the connecting rod 29; the connecting ring 210 is slidably matched with the round rod 25; a floating block Ⅲ21 is fixedly connected to the outer side of the round rod 25, and the floating block Ⅲ21 is located above the fixed cylinder 22; the bottom side of the round rod 25 is fixedly connected to the limiting rod 27. As the liquid level rises, the floating block Ⅲ21 can drive the round rod 25 to move upward, and the floating block Ⅲ21 is always located below the floating block Ⅰ16. Therefore, when the liquid level drops, the floating block Ⅲ21 will drop later than the floating block Ⅰ16, so that the round rod 25 is located above the fixed rod 13 for part of the time, pushing away the garbage above the fixed rod 13.

[0026] A plurality of conical protrusions 28 are fixedly connected to the top side of the round rod 25; a plurality of obliquely arranged transmission plates 26 are provided on the outer circumference 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 drives the transmission plates 26 to move, thereby driving the round rod 25 to rotate, and wrapping up the plastic bag garbage to prevent the garbage from being spread out by the impact of the water flow and covering the upper end of the rectangular cylinder 12, causing a large area of ​​​​blocking and affecting the amount of water entering.

[0027] When the floating block III 21 is driven by the buoyancy to move the round rod 25 upward, the transmission plate 26 moves to the inside of the fixed cylinder 22 along with the round rod 25 .

[0028] The bottom side of the fixed cylinder 22 is connected to a rotating ring 23 through a bearing, and the bottom of the rotating ring 23 is provided with a plurality of notches 24 that slide with the limiting rod 27. After the floating block III 21 moves upward, the limiting rod 27 moves into the notch 24, and after the water flow hits the transmission plate 26, the round rod 25 rotates, and the limiting rod 27 is located in the notch 24 of the rotating ring 23. The rotating ring 23 is connected to the fixed cylinder 22 by a bearing, which can effectively reduce friction.

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

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

[0031] Step 1: When the water inflow per unit time of the drainage port 4 is less than the water discharge 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 amount of water entering the drain port 4 per unit time is greater than the amount of water discharged by the filter plates Ⅰ31 and Ⅱ32 per unit time, rainwater 5 accumulates on the upper ends of the filter plates Ⅰ31 and Ⅱ32, and the volume of rainwater 5 increases, driving the floating blocks Ⅰ16, Ⅱ34 and Ⅲ21 to move upward to avoid clogging of the grate 1.

[0033] The working principle of the present invention is: when the water inflow of the drain port 4 is less than the maximum drainage volume of the control device 3 (i.e., light rain), when the water inflow of the drain port 4 per unit time is less than the drainage volume of the filter plate I 31 and the filter plate II 32 per unit time, 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. Figure 1 Status shown;

[0034] When the amount of water entering the drain port 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 port 4 from the gap between the fixing rods 13. Since the amount of water entering the drain port 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. In the process of the liquid level rising, the floating block II 34 is driven to move upward, and then the floating block II 34 drives the filter barrel 35 and the filter plate II 32 to move upward, so that the rainwater 5 can be discharged through the filter barrel 35, thereby increasing the amount of water discharged and preventing rainwater from accumulating in the drain port 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 floating 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, so that the rainwater 5 in the drain outlet 4 continues to accumulate, the liquid level rises, and the rising liquid level drives the floating block I 16 to move upward, and then drives the rectangular tube 12 to move upward through the connecting rod 15. The rectangular tube 12 is moved so that the height of the rectangular tube 12 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 port 4. In the process of the liquid level rising in the drain port 4, the floating block III 21 also moves upward, and the floating block III 21 drives the round rod 25 to move upward, and then drives 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, Fig. 9 Status shown;

[0036] When the upper end or side of the rectangular tube 12 is blocked by garbage, so that the water inflow is less than the drainage volume 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 floating block I 16 is located at the highest point, during the process of the liquid level dropping, the floating block 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 Fig.10 When the height is shown, since the floating block III 21 is still at the high point due to the buoyancy, the height of the round rod 25 is higher than the height of the fixed rod 13 at this time, and the round rod 25 is located in the gap between two adjacent fixed rods 13, during the downward movement of the rectangular cylinder 12, the round rod 25 will push away the garbage above the rectangular cylinder 12 to avoid the rectangular cylinder 12 being blocked by the garbage. After the garbage is pushed away, the garbage will be washed away by the water flow on the road after leaving the rectangular cylinder 12. The amount of water entering the upper end of the rectangular cylinder 12 is greater than the drainage amount 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 cylinder 12 to move upward and reach the height as shown in the figure. Fig. 9 Status shown;

[0037] When the garbage blocked by the upper end of the rectangular tube 12 is a plastic bag or a packaging bag, due to the obstruction of the plastic bag or the packaging bag, the water inflow of the rectangular tube 12 is reduced and is less than the water discharge, causing the liquid level to drop continuously. In the above manner, the rectangular tube 12 moves downward, and the height of the round rod 25 is higher than the height of the fixed rod 13, pushing away the packaging bag that is not easy to curl, so that it flows with the water flow and leaves the rectangular tube 12, while the plastic bag-like garbage will stick to the top and side of the round rod 25 under the impact of the water flow. During the process of the liquid level dropping in the drain port 4, part of the rainwater 5 will flow downward through the fixed tube 22, and after the round rod 25 moves upward, the transmission plate 26 is located in the fixed tube 22, and the rainwater 5 flowing downward will continue to push the oblique The transmission plate 26 is set to rotate, and 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 garbage attached to the top and side of the round rod 28, thereby causing the plastic bag garbage to be entangled on the side of the round rod 25, so that after the plastic bag garbage is impacted by the water flow, its unfolding area is reduced, thereby reducing the shielding of the upper end of the rectangular tube 12. After the plastic bag or packaging bag garbage is removed, the water inflow at the upper end of the rectangular tube 12 is greater than the drainage volume of the filter plate I 31, the filter plate II 32, and the filter barrel 35, so that the liquid level in the drainage port 4 rises again, thereby driving the rectangular tube 12 to move upward and reach the state as shown in the figure. Fig. 9 Status shown.
