Description

Technical Field

[0001] This utility model relates to the field of pneumatic shield gate maintenance technology, specifically a flood control pneumatic shield gate. Background Technology

[0002] A pneumatic shield gate is a flexible water-blocking structure driven by air or water pressure. It mainly consists of a shield body made of high-strength rubber composite material, a pneumatic control system, and anchoring components. Its working principle involves inflating the shield body by filling internal air pockets with compressed air or water, forming a water barrier. After the air is released, the shield body collapses, restoring flow. This gate features rapid opening and closing, no need for mechanical transmission components, good seismic performance, and eco-friendliness. It is suitable for urban flood control, tide control, and farmland irrigation. However, during use, silt flows with the water and settles near the gate, reducing the actual water depth and requiring regular cleaning.

[0003] For example, the patent with authorization announcement number CN210002330U discloses a flood control pneumatic shield gate that uses water pressure to accelerate the flow of water and carry the silt and dirt at the bottom of the water through the inlet bucket into the U-shaped pipe, corrugated pipe, first water pipe and second water pipe and then discharges it. By setting multiple second water pipes, it is convenient to open the second water pipes at different positions according to the water level to adapt to the water level and maintain the water pressure, thereby maintaining the water flow rate to carry away the silt and dirt. However, there are still areas for improvement.

[0004] When silt accumulates at the bottom of the water body, it is not easy for the silt to be flushed out with the water flow when the valve is opened. Moreover, after the silt settles, it is relatively solid and there may be blockages of the second water pipe and valves. Furthermore, the blockage point is located underwater, making it inconvenient to clear. Utility Model Content

[0005] To address the aforementioned issues, this application provides a flood control pneumatic shield gate that solves the problem of silt accumulating at the bottom of water bodies and not easily flowing out under the impact of water flow.

[0006] A flood control pneumatic shield gate includes a shield plate, an airbag for supporting the shield plate is installed on the outside of the shield plate, a base plate is hinged to the bottom of the shield plate and fixed to the ground, and multiple air jets for blowing away silt are embedded in the top of the base plate.

[0007] A first electric valve is fixedly installed on the outside of the airbag, and the first electric valve is connected to the jet head through a pipe;

[0008] The shield plate has multiple sewage discharge holes through the middle for sewage discharge, and a second electric valve for controlling the opening and closing of the sewage discharge holes is fixedly installed inside the sewage discharge holes.

[0009] The outer side of the shield plate has a backwash hole that is connected to the sewage discharge hole. The outer side of the airbag is connected to and fixedly installed with a third electric valve. The third electric valve is connected to the backwash hole through a pipe.

[0010] Preferably, a large isolation net is fixedly installed on the top of the base plate, and the large isolation net covers the jet head.

[0011] Preferably, a small isolation net is fixedly installed on the outside of the shield plate, and the small isolation net covers the sewage discharge hole.

[0014] Preferably, the bottom of the airbag is fixedly installed on the ground.

[0015] Preferably, an underwater camera is installed on the side of the shield plate closest to the bottom plate.

[0016] Preferably, the outer sides of the first electric valve, the second electric valve, and the third electric valve are all coated with a corrosion-resistant coating.

[0017] The beneficial effects of this utility model are as follows:

[0018] The present invention describes a pneumatic shield gate for flood control. Before discharging silt, high-pressure gas is sprayed onto the silt, causing the silt to disperse and move upward, and then dispersed again into the bottom water flow. Then, the second electric valve is opened, and under the action of water pressure, the bottom water flow carries the silt out. The silt is first lifted and then discharged, so that the silt is discharged more thoroughly.

[0019] After a period of discharge, the drain hole and small isolation net may be covered and blocked by leaves and other impurities, causing the water flow of the second electric valve to be slower. At this time, the second electric valve can be closed and the third electric valve can be opened to backwash and unclog the drain hole and small isolation net. No staff need to go into the water to operate. After backwashing, the sewage discharge operation can continue. Attached Figure Description

Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0029] As shown in Figures 1-5, this utility model embodiment provides a flood control pneumatic shield gate, including a shield plate 1. An airbag 5 is installed on the outside of the shield plate 1 to support it and is used to inflate and support the shield plate 1. The bottom of the airbag 5 is fixedly installed on the ground. An inflation pipe 14 is fixedly installed at the end of the airbag 5. The inflation pipe 14 is connected to an external inflation mechanism. The inflation mechanism inflates the airbag 5 through the inflation pipe 14. The inflation mechanism can also be connected to a pneumatic mechanism to facilitate knowing the air pressure inside the airbag 5.

[0030] The bottom of the shield plate 1 is hinged to a base plate 2 for receiving silt. The base plate 2 is fixed to the ground. Multiple jet nozzles 7 are embedded in the top of the base plate 2 for blowing away the silt and dispersing it into the bottom water flow.

[0031] A first electric valve 8 is fixedly installed on the outside of the airbag 5, and the first electric valve 8 is connected to the jet head 7 through a pipe.

[0032] In this embodiment, when discharging sludge, the first electric valve 8 is opened, and high-pressure gas is sprayed from the first electric valve 8, the pipeline, and the jet nozzle 7 onto the sludge, causing the sludge to disperse, move upward, and disperse again into the bottom water flow for easy discharge.

[0033] The shield plate 1 has multiple sewage discharge holes 10 through the middle for sewage discharge, and a second electric valve 11 for controlling the opening and closing of the sewage discharge holes 10 is fixedly installed inside the sewage discharge holes 10.

[0034] In this embodiment, the second electric valve 11 is opened. Under the action of water pressure, the bottom water flow carries the sludge out from the drain hole 10 and the second electric valve 11, first lifting the sludge and then discharging it, so that the sludge is discharged more thoroughly.

[0035] A backwash hole 12 connected to the sewage discharge hole 10 is provided on the outer side of the shield plate 1. A third electric valve 13 is fixedly installed on the outer side of the airbag 5. The third electric valve 13 is connected to the backwash hole 12 through a pipe.

[0036] In this embodiment, before discharging sludge, the inflation mechanism inflates the airbag 5 through the inflation pipe 14, the third electric valve 13 is opened, and high-pressure gas is sprayed from the third electric valve 13, the pipe, and the backwash hole 12 to the drain hole 10 to clear and clean the impurities that adhered to the inside of the drain hole 10 during the water storage period.

[0037] When discharging sludge, the third electric valve 13 is closed. After a period of discharge, the drain hole 10 may be covered and blocked by leaves and other impurities, causing the water flow of the second electric valve 11 to be slower. At this time, the second electric valve 11 can be closed and the third electric valve 13 can be opened to backwash and unclog the drain hole 10. No staff need to go into the water to operate. After backwashing, the sewage discharge operation can continue.

[0038] Specifically, a large isolation net 6 is fixedly installed on the top of the base plate 2. The large isolation net 6 covers the jet head 7 to prevent large particles of impurities from clogging the jet head 7. The mesh of the large isolation net 6 can disperse the high-pressure airflow into multiple streams, thereby making the sludge more dispersed and less likely to clog the drain hole 10.

[0039] Specifically, a small isolation net 9 is fixedly installed on the outside of the shield plate 1, and the small isolation net 9 covers the sewage discharge hole 10 to prevent large particles of impurities from clogging the sewage discharge hole 10.

[0040] Specifically, the shield plate 1 is symmetrically equipped with ground rails 3 at both ends. The ground rails 3 are fixedly installed on the ground. The top of the ground rails 3 is provided with a sliding groove 15. A hinge plate 4 is slidably installed inside the sliding groove 15. The top of the hinge plate 4 is hinged to the shield plate 1. The ground rails 3 and the hinge plate 4 are used to assist the airbags in supporting the shield plate 1.

[0041] Specifically, an underwater camera is installed on the side of the shield plate 1 near the bottom plate 2, which allows staff to view the underwater situation and thus determine the timing and progress of silt removal.

[0042] Specifically, the outer sides of the first electric valve 8, the second electric valve 11, and the third electric valve 13 are all coated with a corrosion-resistant coating, which can extend their service life.

[0043] Specific working methods:

[0044] Silt settles on the bottom plate 2 with the water flow. The inflation mechanism inflates the air bag 5 through the inflation pipe 14. The third electric valve 13 is opened. High-pressure gas is sprayed from the third electric valve 13, the pipe, and the backwash hole 12 to the drain hole 10 and the small isolation net 9 to unclog and clean the impurities that adhered to the inside and outside of the drain hole 10 and the small isolation net 9 during the water storage period.

[0045] The third electric valve 13 is closed, and the first electric valve 8 is opened. High-pressure gas is sprayed from the first electric valve 8, the pipeline, and the jet nozzle 7 onto the sludge, causing the sludge to disperse and move upward, and then disperse again into the bottom water flow. The second electric valve 11 is opened, and under the action of water pressure, the bottom water flow carries the sludge out from the drain hole 10 and the second electric valve 11, first lifting the sludge and then discharging it, so that the sludge is discharged more thoroughly. After a period of discharge, the drain hole 10 and the small isolation net 9 may be covered and blocked by leaves and impurities, making the water flow of the second electric valve 11 slower. At this time, the second electric valve 11 can be closed and the third electric valve 13 can be opened to backwash and unclog the drain hole 10 and the small isolation net 9. No staff need to go into the water to operate. After backwashing, the sewage discharge operation can continue.

[0046] The mesh of the large isolation net 6 can disperse the high-pressure airflow into multiple streams, thereby making the sludge more dispersed and less likely to clog the sewage outlet 10.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
