At present, in many cities, due to the fact that underground network management is imperfect, when precipitation is large, water accumulation is too much or drainage is not good, and therefore serious waterlogging of the cities occurs. When a flood season occurs, flood prevention emergency departments often discharge flood and discharge flood in serious areas of the flood season by adjusting and collecting drainage pumps. At this time, the number and the discharge capacity of the drain pump mean the magnitude of the flood discharge capacity. As the current main emergency rescue mode, a mobile submersible pump is mostly used for flood drainage. Usually, submersible pumps are mounted on movable platforms such as special vehicles, and after the submersible pumps are connected to upper drainage pipelines on site, the submersible pumps are transported and thrown into flood, and the drainage pipelines are led out to channels which can naturally and smoothly drain the flood, such as sewer, low-lying places, ditches, rivers and the like. This mode can satisfy flood discharge and flood discharge requirements to a certain extent, but also has the following defects:

Secondly, the high-power submersible pump needs to use high-voltage high-frequency power electricity, and the pump works underwater for a long time, so that potential safety hazards can be brought.
The defects are determined by the principle of the submersible pump, cannot be completely avoided, and only some flexible methods can be adopted in practical application. For example, the shell of the submersible pump is changed into lighter aluminum alloy; the power of a single pump is kept unchanged, and the number of pumps is increased; carrying a submersible pump by the amphibious crawler and driving into water; by driving a hydraulic submersible pump by means of a hydraulic station instead, etc. However, these approaches increase the overall cost of the device and introduce new problems. The high cost makes this drain difficult to use on a large scale. From cost and efficiency, centrifugal pump also by the wide application in the drainage field, centrifugal pump's the position of placing may be higher than the level of drawing water, difficulty and the potential safety hazard under the water of throwing before having solved the drainage of high-power immersible pump are thrown. However, the limitation of the water discharge of a single water pump is to satisfy the requirement of larger flood discharge capacity, increase the water discharge of flood discharge and shorten the time of flood discharge, and only the realization is realized by adding more matched water pumps.

The utility model discloses, centrifugal pump 13 is the suction pump among the current pumping and drainage system, and main line 1 can be for the pipeline that is used for the pumping and drainage water that is connected with the suction pump among the current pumping and drainage system.
Since the centrifugal water pump 13 may be placed at a higher level than the water pumping level, the centrifugal water pump 13 is generally installed on land or on a moving platform such as an automobile. So, when using at every turn, need at first carry out the diversion with main inlet tube 11 entry to the injected water between the centrifugal pump 13 delivery port, accomplish after the diversion, centrifugal pump 13 just can normally work, so need the diversion device to be main pipeline 1 diversion usually. Conventional manual water injection, a special pump or a tap water pipeline and the like can be generally adopted as the water diversion device.
In order to facilitate the use, the water diversion device of the utility model comprises a water diversion pipeline 3 and a submersible pump 34; the drainage pipeline 3 comprises a drainage water inlet pipe 31, a drainage water outlet pipe 32 and a drainage branch pipe 33; the inlet of the drainage water inlet pipe 31 is connected with the water outlet of the submersible pump 34; the outlet of the drainage water inlet pipe 31, the inlet of the drainage water outlet pipe 32 and the inlet of the drainage branch pipe 33 are connected through a three-way stop valve B7; the outlet of the branch drainage pipe 33 is communicated with the main drainage pipe 12.
The drainage pipeline 3 is used for filling water between the water outlet of the centrifugal water pump 13 and the inlet of the main water inlet pipe 11 to finish water drainage so as to ensure the normal work of the centrifugal water pump 13. The three-way stop valve B7 has three ports, namely an inlet A, an outlet B and an outlet C, wherein the inlet A is connected with the outlet of the drainage water inlet pipe 31, the outlet B is connected with the inlet of the drainage water outlet pipe 32, and the outlet C is connected with the inlet of the drainage branch pipe 33. During specific work, put into aquatic with immersible pump 34, switch three-way stop valve B7, make A entry and C export intercommunication, immersible pump 34 is gone into water by the entry pump of drainage inlet tube 31, because the B export of three-way stop valve B7 is closed, then water pours into the delivery port pipeline suitable position and the main inlet tube 11 of centrifugal pump 13 into by drainage branch pipe 33, because install check valve 8 at the entry of main inlet tube 11, this check valve 8 makes rivers can follow the entry flow direction export of main inlet tube 11, and can not flow into the entry by the export, so, in main pipeline 1, the water that immersible pump 34 taken out can only flow into in main pipeline 1, and can not flow out by the entry of main inlet tube 11, thereby make all progressively injected water in the main pipeline 1 that centrifugal pump 13 is connected. When the water level in the main pipeline 1 reaches a certain position, water diversion is completed, and the centrifugal water pump 13 can work normally.
The three-way shut-off valve a6 also has three ports, i.e., an inlet a, an outlet B, and an outlet C, wherein the inlet a and the outlet B are connected to the main drain pipe 12, and the outlet C is connected to the inlet of the overflow branch pipe 23. When the submersible pump 34 pumps water, the outlet B of the three-way stop valve A6 is closed, namely the main drain pipe 12 is closed, the outlet C is opened, the main water inlet pipe 11 and the overflow pipeline 2 are communicated, and the whole pipeline is ensured to be in an open state without forming blockage. Meanwhile, after the centrifugal water pump 13 works, a large amount of water is pumped into the main pipeline 1 through the centrifugal water pump 13, the three-way stop valve A6 is closed in the direction of the main pipeline 1 and is opened in the direction connected with the overflow pipeline 2, at the moment, the water directly enters the overflow pipeline 2, meanwhile, the check valve 8 is also installed at the inlet of the overflow water inlet pipe 21, under the action of the check valve 8, at the moment, the water can only flow to the outlet of the overflow drain pipe 22 along the overflow pipeline 2 until the whole overflow pipeline 2 is full of the water, and therefore water diversion of the overflow pipeline 2 is completed. At this time, the outlet C of the three-way stop valve a6 is closed, the outlet B is communicated, the connection path between the three-way stop valve a6 and the overflow pipeline 2 is cut off, the main water inlet pipe 12 and the centrifugal water pump 13 are communicated, the centrifugal water pump 13 still works normally, water is sucked in from the main water inlet pipe 11 under the action of the centrifugal water pump 13, passes through the centrifugal water pump 13, and is discharged through the outlet of the main water outlet pipe 12, namely, water is discharged from the main water outlet pipe 12. Meanwhile, since the overflow is formed in the overflow line 2, when the inlet of the overflow inlet pipe 21 is located at a position higher than the outlet of the overflow drain pipe 22, part of the water will be sucked into the overflow drain pipe 22 along the overflow inlet pipe 21 under the action of the pressure difference, and the overflow will be formed naturally.
Because the submersible pump 34 is only used for water diversion, a low-power submersible pump can be adopted, the carrying is convenient, and the safety problem is small. And through pump diversion, more reliable, degree of automation is higher. In order to further improve the automation degree, an automatic control box 9 and a liquid level measuring sensor 4 are also arranged, and the liquid level measuring sensor 4 is arranged on the flow path of the main drainage pipe 12; the liquid level measuring sensor 4 detects liquid level information in the main drainage pipe 12 and transmits the liquid level information to the automatic control box 9, and the automatic control box 9 instructs the centrifugal water pump 13 to be opened and closed according to flowing water information. When the automatic control box 9 is in specific work, when the liquid level measuring sensor 4 detects that the water level in the main pipeline 1 reaches a designed position, the centrifugal water pump 13 is instructed to be automatically started to pump water; when the liquid level measuring sensor 4 detects that the water level in the main pipeline 1 is lower than the designed position, the automatic control box 9 instructs the centrifugal water pump 13 to automatically close, and water pumping is stopped.
The three-way stop valve a6 can be located the rear of level measurement sensor 4, so, the surface of water of main pipeline 1 surpasss three-way stop valve a6 and when the level measurement sensor 4, just can close immersible pump 34, starts centrifugal water pump 13, and at this moment, the water of immersible pump 34 suction flows into overflow inlet tube 21 through three-way stop valve a6 a large amount to extension immersible pump 34 operating time. In order to shorten the priming time of the submersible pump 34 and to put the centrifugal pump 13 into operation as soon as possible to improve the operating efficiency, it is preferable that the three-way shut-off valve a6 be located in front of the liquid level measuring sensor 4 along the flow path of the main line 1.
The device is used, firstly, under the condition of pumping and draining water of the main pipeline 1, the pumping and draining water of the overflow pipeline 2 is added, so that the pumping and draining capacity is improved to a great extent; secondly, the overflow pipeline 2 adopts natural overflow pumping drainage, does not need to add extra power equipment, does not accompany with energy consumption, and belongs to green environment-friendly pumping drainage; thirdly, the water-saving device is directly connected with a pipeline of the existing drainage system through a three-way stop valve, is seamlessly integrated with the existing drainage system, and has little influence on the existing drainage system; fourthly, a centrifugal water pump is adopted for pumping and draining water, so that the problem and potential safety hazard of the high-power submersible pump under water feeding before drainage are solved; fifthly, the submersible pump 34 is adopted to conduct water diversion on the main pipeline 1, the centrifugal pump 13 on the main pipeline 1 is adopted to conduct water diversion on the overflow pipeline 2, water diversion is rapid, and the overflow pipeline 2 is made to be put into drainage work as early as possible.
In the using process, if the overflow effect is not formed, compensation operation is needed, namely, the submersible pump 34 is used for leading water to fill the whole overflow pipeline, water is ensured to be in the main pipeline, the centrifugal pump can work to form automatic overflow efficiency, and if overflow cannot be formed actually, the centrifugal pump is switched to a pumping and draining work mode of the conventional centrifugal pump 13. It is possible to determine by human that the inlet of the overflow inlet pipe 21 is located at a position higher than the outlet of the overflow drain pipe 22, however, there are also cases where it is difficult to clearly determine by human whether overflow drain can be taken. In order to accurately judge whether the overflow effect is formed, the device also comprises a flow measuring sensor 5, wherein the flow measuring sensor 5 is arranged on the flow path of the overflow drain pipe 22; the flow measuring sensor 5 detects the water flow information in the overflow drain pipe 22 and transmits the water flow information to the automatic control box 9, and the automatic control box 9 instructs the three-way stop valve a6 to open and close the passage between the overflow branch pipe 23 and the main drain pipe 12 according to the water flow information.
The detection of the water flow information in the overflow line 2 is carried out by the flow measuring sensor 5, which indicates that the self-overflow drain is established and works normally as long as normal flow is always present. If the normal flow is not possible, the position of the inlet of the overflow inlet pipe 21 and the outlet of the overflow drain pipe 22 may be difficult to satisfy the overflow condition, and the position of the outlet of the overflow drain pipe 22 may be selected again or the self-overflow drain mode may be terminated.
