Therefore, when the fire pump is performing a pumping operation, it is necessary to drain water so that water can be diverted into the pool. Currently, most common drainage methods are manual drainage, which not only consumes manpower, but also requires entering the pool or river for manual operation when the water level in the pool is low. Drainage is very inconvenient and can easily cause safety accidents. Summary of the invention

[0005] Furthermore, the controller of the driving motor is configured as a wireless control device, which includes a wireless receiver and a wireless remote controller. The wireless receiver is installed at the control port of the driving motor, and the wireless receiver and the wireless remote controller are connected by wireless communication corresponding to a wireless communication protocol.
[0006] Furthermore, an equipment inspection port is provided at the bottom end of the shell, a flippable cover is installed on the equipment inspection port, and one end of the cover is rotatably connected to the equipment inspection port.
[0007] Furthermore, the drainage chamber includes a vertical chamber at the top and a horizontal chamber at the bottom. The vertical chamber is connected to the horizontal chamber in an inverted T-shaped structure. The upper end of the vertical chamber is connected to the water inlet through the water inlet pipe, and the lower end of the vertical chamber is connected to the middle of the horizontal chamber. The spiral blade is installed in the horizontal chamber. After the driving motor drives the spiral blade to rotate, the spiral force generated by the rotation of the spiral blade can absorb the water flow from top to bottom from the vertical chamber to the horizontal chamber. The outlet of the drainage chamber is located at one end of the horizontal chamber, and the outlet of the drainage chamber is connected to the upward water outlet pipe through a bend, and a one-way valve I is installed in the water outlet pipe.
[0008] Furthermore, the upper water outlet channel and the lower water outlet channel are both configured as horizontal channels, a one-way valve II is provided in the upper water outlet channel, the one-way valve II is fixedly mounted on the upper sealing mounting plate through a fixing frame, the inlet of the one-way valve II is opposite to the outlet of the water outlet pipe, the lower water outlet channel is located at the lower part of the upper water outlet channel, the outlet of the one-way valve II is downwardly located in the inlet of the lower water outlet channel, and the outlet of the lower water outlet channel located on the side of the shell is connected to the water inlet channel of the centrifugal pump.
[0009] Furthermore, the filter is a stainless steel filter.
[0010] The present invention has the following beneficial effects: after adopting the above technical scheme, the present invention allows water to enter the drainage chamber through the water inlet and the filter screen, and then remotely controls the driving motor located in the pool to rotate through a wireless remote controller, the driving motor drives the spiral blades to rotate, and the spiral blades generate a spiral force in the drainage chamber to form water pressure to make the water flow in the horizontal chamber flow upward from the water outlet pipe through the one-way valve I into the upper water outlet channel, and then flow from the upper water outlet channel into the lower water outlet channel, and then the negative pressure generated by the centrifugal pump is used to absorb the water entering the lower water outlet channel into the centrifugal pump to perform water diversion on the centrifugal pump. The invention can realize water start-up when the centrifugal pump is started, so that the centrifugal pump can be started remotely without manual operation or entering the water for operation. The centrifugal pump placed in the water can be drained conveniently, ensuring the water diversion function while improving the convenience and safety of operation. The spiral blades are used to generate a spiral force in the drainage chamber to form water pressure to make the water flow in the horizontal chamber enter the upper water outlet channel from the water outlet pipe upward. Since the water diversion efficiency is relatively high and the water diversion volume is relatively large, the drainage continuity is relatively good, thereby greatly improving the pumping efficiency of the centrifugal pump. Due to the action of the one-way valve I of the present invention, the water flow entering the upper water outlet channel cannot flow back to the water outlet pipe and the drainage chamber. Due to the action of the one-way valve II, the water flow entering the lower water outlet channel cannot flow back to the upper water outlet channel. This can further ensure the efficiency and smoothness of the drainage and avoid the interruption of the drainage caused by the backwater. The filter screen of the present invention is a stainless steel filter screen, which can ensure that the filter screen will not rust and ensure the performance of use.

[0016] The use process of the present invention is as follows: the water in the pool flows into the working chamber through the water inlet 11 and the filter screen 12 of the electric water diverter, and then enters the vertical chamber 20 and the horizontal chamber 21 of the drainage chamber 10 in sequence through the water inlet pipe 13, the water flow is attracted from the vertical chamber 20 to the horizontal chamber 21, and then a signal is sent to the wireless receiver 16 through the wireless remote controller 17 to remotely control the driving motor 6 located in the pool to rotate, the driving motor 6 drives the spiral blade 9 to rotate, and the spiral blade 9 generates a spiral force in the drainage chamber 10 to form a water pressure to make the water flow in the horizontal chamber 21 upward from the water outlet pipe 14 through the one-way valve I2 into the upper water outlet channel 15, because the one-way valve I 2, the water flow entering the upper water outlet channel 15 cannot flow back into the water outlet pipe 14 and the drainage chamber 10, and enters the upper water outlet channel 15 and then flows into the lower water outlet channel 22 through the one-way valve II 23 and the inlet of the lower water outlet channel 22.
