[0004] Similar drainage devices in water conservancy projects, because the water flow will carry a large amount of solid particles such as mud, dirt, etc., the long-term water flow process will cause the mud particles to gradually settle at the bottom of the water body, resulting in mud accumulation and difficulty in dredging. In addition, because there are often floating objects on the water surface, when the water flows to the outlet, if there are too many floating objects, they will eventually gather at the outlet and cannot be discharged smoothly, causing blockage.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an emergency drainage water conservancy engineering device is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide an emergency drainage water conservancy engineering device. Since the water flow may carry a large amount of solid particles such as mud, dirt, etc., a long-term water flow process will cause the mud particles to gradually settle at the bottom of the water body, resulting in mud accumulation and difficulty in dredging. Moreover, since there are often floating objects on the water surface, when the water flows through the water outlet, if there are too many floating objects, they will eventually accumulate at the water outlet and cannot be discharged smoothly, causing blockage.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an emergency drainage water conservancy engineering device, comprising a water reservoir, an inlet pipe, an outlet pipe and a drain, a water inlet is provided at the center of the left side of the water reservoir, a water outlet is provided at the center of the right side of the water reservoir, a first electronic valve is provided on the outward side of the water inlet and the water outlet, the water inlet pipe is provided on the left side of one group of the first electronic valves, the water outlet pipe is provided on the right side of another group of the first electronic valves, a drain is provided at the center of the lower end surface of the water reservoir, a second electronic valve is provided on the lower end surface of the drain, a drain pipe is provided on the lower end surface of the second electronic valve, a sewage pipe is provided on the right side of the inner cavity of the water reservoir, a float-type water level sensor is provided on the left side of the inner cavity of the water reservoir, a water pump is provided on the upper end surface of the right side of the water reservoir, and a sewage pipe is provided at the output end of the water pump.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] like Figures 1 to 4 As shown, an emergency drainage water conservancy engineering device includes a water reservoir 1, an inlet pipe 4, an outlet pipe 5 and a drain 7. A water inlet 2 is opened at the center of the left side of the water reservoir 1. The water inlet 2 is a channel for water to enter the water reservoir 1. The water reservoir 1 provides a flow and accumulation space for water. The water flows through the water reservoir 1 and then enters the outlet 3. A water outlet 3 is opened at the center of the right side of the water reservoir 1. The water outlet 3 is used to discharge the water. The positions of the water inlet 2 and the water outlet 3 are at the same level and correspond to each other. When the water from the water inlet 2 flows into the water reservoir 1 and is filled to the same height as the water reservoir 1, it can be discharged from the outlet 3 at another level, so that the silt is settled to the bottom when the silt water flows through and will not flow with the silt. The water flows are discharged from the water outlet 3 together, so as to keep the water clean. The first electronic valve 6 is arranged on the outward side of the water inlet 2 and the water outlet 3. The two groups of first electronic valves 6 control the opening and closing of the water inlet 2 and the water outlet 3. The water inlet pipe 4 is arranged on the left side of one group of the first electronic valves 6. The water inlet pipe 4 is connected with the water inlet 2 through one group of the first electronic valves 6. The water inlet pipe 4 guides the water flow to enter the water inlet 2 through the opening and closing of the first electronic valve 6. The water outlet pipe 5 is arranged on the right side of the other group of the first electronic valves 6. The water outlet pipe 5 is connected with the water outlet 3 through the other group of the first electronic valves 6. The water outlet 3 is opened or closed by the first electronic valve 6, and the water flow is guided to be discharged from the water outlet pipe 5.

[0023] The bottom of the inner cavity of the water storage tank 1 is funnel-shaped. The funnel-shaped water storage tank 1 is conducive to the accumulation of sludge and debris, so that it is deposited at the bottom and discharged to the drain port 7 with the flow vortex of water, so as to facilitate cleaning and excretion. A drain port 7 is opened at the center of the lower end surface of the water storage tank 1. The drain port 7 is used for emergency dredging and water discharge. The lower end surface of the drain port 7 is provided with a second electronic valve 9. The second electronic valve 9 is controlled to open and close by a control system. The lower end surface of the second electronic valve 9 is provided with a drain pipe 8. The drain pipe 8 guides the water to be discharged. The drain port 7 is connected to one end of the drain pipe 8 through the second electronic valve 9. The drain port 7 is in the conveying drain pipe. 8 is restricted and opened by the second electronic valve 9 to realize the control of water flow. A float type water level sensor 10 is arranged on the left side of the inner cavity of the water reservoir 1. A floating ball 101 is sleeved on the rod body of the float type water level sensor 10. The floating ball 101 floats up and down together with the water level on the rod body of the float type water level sensor 10 through its own buoyancy. The float type water level sensor 10 transmits the water level value to the control system. The float type water level sensor 10 is connected to the side wall of the water reservoir 1 through a connecting ring 11. The connecting ring 11 is provided with two groups. The float type water level sensor 10 is fixed in the water reservoir 1 through the two groups of connecting rings 11.

[0024] A water pump 13 is arranged on the upper end surface of the right side of the water reservoir 1, and the water pump 13 is used to pump water. A sewage pipe 12 is arranged on the right side of the inner cavity of the water reservoir 1. The shape of the sewage pipe 12 is Z-shaped. The end of the sewage pipe 12 away from the water outlet 3 is connected to the input end of the water pump 13. The sewage pipe 12 extracts the floating debris on the water surface through the suction force of the input end of the water pump 13, and discharges it from the output end of the water pump 13. A sewage pipe 14 is arranged at the output end of the water pump 13, and one end of the sewage pipe 14 is connected to the output end of the water pump 13. The sewage pipe 14 guides the drifting impurities discharged by the water pump 13, and discharges the extracted sewage impurities to a designated place to ensure smooth treatment and discharge of sewage.

[0025] In summary, if Figures 1 to 4 As shown, in the emergency drainage water conservancy engineering device, the water inlet pipe 4 guides the water flow into the water inlet 2, and after the water flows to the water reservoir 1 and is filled to the same height as the water reservoir 1, it can be discharged from another horizontal water outlet 3, and the water outlet pipe 5 guides the water at the water outlet 3, and in the process of water flow, the silt gradually settles to the bottom of the funnel. The float 101 of the rod body of the float-type water level sensor 10 between the two sets of connecting rings 11 floats according to the height of the water level, so that the float-type water level sensor 10 detects whether the water level is consistent through a preset threshold value. When the threshold value is exceeded, a signal is sent to the control system to control the two sets of first electric The sub-valve 6 is closed, and the second electronic valve 9 at the drain port 7 is opened, so that the water flow of the water reservoir 1 is discharged along the drain port 7. When draining, the water flow will generate vortex, driving the mud and sand at the bottom of the funnel to be discharged from the drain port 7, and flow through the drain pipe 8 to the designated drainage point. Since there will be floating objects such as plants on the water surface, these floating objects will gather at the water outlet 3 with the water flow and accumulate, causing the water outlet 3 to be blocked. The water flow and floating objects are extracted together by the sewage pipe 12 through the input end of the water pump 13 and sent to the sewage pipe 14 at the output port, and then the sewage impurities extracted are discharged to the designated place by the sewage pipe 14.
