Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme:
when the siphon generator is used, firstly, parameters of a control panel are manually set, such as the starting sequence of electrical equipment in the siphon generator; the drainage well and the water storage tank are communicated through a siphon pipeline, the position of the drainage well is guaranteed to be higher than the water storage tank, the water column pressure difference between the drainage well and the water storage tank is convenient to form, and water flow in a tunnel is convenient to discharge.
The first stage, when the drainage system starts to work, the siphon generation device is manually controlled to work through the control panel, at the moment, the drainage electromagnetic valve is closed, the gas electromagnetic valve is opened, the air compressor is started, and the air compressor can suck air in the water storage tank; after the air compressor operates for a period of time, because the water storage tank is sealed, one end position of the siphon pipeline is positioned below the liquid level of the drainage well, the air pressure in the water storage tank is lower than the air pressure in the drainage well, and the drainage well is positioned higher than the water storage tank, so that water in the drainage well can be extruded by air to enter the siphon pipeline.
When the air squeezes the water in the siphon pipeline to flow through the highest point in the pipeline, the water flow can rapidly enter the water storage tank due to the gravity of the water flow and the air pressure difference between the water storage tank and the drainage well, and the siphon phenomenon is formed.
The second stage, the floating block can float on the liquid level, when the rivers in the water storage tank were crossed control panel's height, control panel's order receiving module can receive the first time position signal of floating block, control panel's CPU can analyze the first time position signal of floating block and send the order through order output module, control panel can postpone a period start-up procedure order (this time is according to siphon pipeline's rivers flow decision, the liquid level that enables the water storage tank is higher than control panel's height, but the liquid level in the water storage tank can not fill the water storage tank), at this moment, the drainage solenoid valve is opened, the gas solenoid valve is opened, the air compressor machine is closed, the water in the water storage tank can be followed the drain pipe and is discharged.
In the third stage, when the siphon pipelines stop running due to accidents, for example, the positive and negative pressures of a siphon drainage system are out of control due to the infiltration of outside air and other reasons, and some siphon pipelines are blocked by silt; the water injection amount of the siphon pipeline can be reduced, the water drainage pipeline still normally and continuously drains water, and the liquid level in the water storage tank can be continuously reduced.
When the liquid level in the water storage tank is lower than the height of the control panel, the command receiving module of the control panel can receive the second position signal of the floating block, the CPU of the control panel can analyze the second position signal of the floating block and send a command through the command output module, the command output module of the control panel can immediately close the drainage electromagnetic valve, the gas electromagnetic valve is opened, the air compressor is started, the air compressor can inject the external air into the water storage tank, the pressure in the water storage tank can be continuously increased (because the siphon pipeline is blocked, the siphon drainage system causes drainage interruption due to accidents, one end of the siphon pipeline is positioned below the liquid level of the drainage well, and therefore, the inside of the water storage tank is in a sealing state).
After the air compressor machine operation a period, because under the liquid level of the sealed and siphon pipeline's of water storage tank and the water storage tank, the air pressure in the water storage tank is higher than the air pressure in the drainage well, so water in the water storage tank can be overcome rivers self gravity by air extrusion entering siphon pipeline in, form the adverse current, the adverse current can erode the silt choke point of siphon pipeline at the in-process that flows through siphon pipeline, make it block up the silt in the siphon pipeline and clear up.
When the upstream in the air extrusion siphon pipeline flows through the peak in the pipeline, the upstream can be because the gravity of self and the air pressure differential between water storage tank and the drainage well, the upstream can get into the drainage well fast, make water storage tank and drainage well intercommunication, control panel can close the air compressor machine this moment, because the air compressor machine is no longer working, so, water storage tank and drainage well air pressure differential are not enough to promote the upstream, the upstream can make siphon drainage system restart once more because of the gravity of self, when the rivers in the water storage tank cross control panel's height, the second stage of repetition, when the siphon pipeline stops the operation because of the accident once more, the third stage of repetition, until the interior rivers evacuation of drainage well.
