Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, in particular to an integrated prefabricated flood control pumping station. Background Art

[0002] A submersible pump is a widely used water pumping and drainage device. During specific operation, it is put into relevant waters, and then it pumps the water at a lower position and discharges it to a higher position through a hose or the like.

[0003] With the progress of industrial technology, the functions of submersible pumps have also developed. The authorized patent with the patent number "201920137590.0" and the patent name "Energy-saving Submersible Pump" in China records that "it alleviates the technical problem existing in the prior art that due to the high-speed rotation of the impeller, it will drive the liquid to rotate in the base, and the liquid cannot quickly and centrally enter the pump body of the submersible pump, resulting in low pumping efficiency of the submersible pump, and realizes that the liquid quickly and centrally enters the pump body of the submersible pump, improving the pumping efficiency of the submersible pump". As can be seen from the above patent, although it achieves its stated invention purpose, like other existing devices in this field, it is still limited by the structure and has some specific technical problems, which are specifically reflected as follows. Since there is no handle or the like on the submersible pump, it is not convenient for the staff to move its position by hand, which will bring some inconvenience to the staff more or less. Moreover, when the existing submersible pump is used for drainage in relevant specific areas (such as for draining sudden water accumulation due to rain in underground parking lots and other low-lying areas), generally, after the water accumulates to a certain depth in the on-site area, the staff turns on the power switch of the submersible pump, and then the submersible pump pumps out the water in the corresponding area. After the water is discharged to a certain level, the power switch is turned off and the submersible pump loses power and stops working; in the above operation mode, since the opening or closing of the power switch requires manual operation, it will also bring inconvenience to the staff. More importantly, if the water depth in the relevant area is relatively large and the staff does not arrive at the scene in time for operation, the on-site accumulated water cannot be discharged in time, and there is a risk that the surrounding equipment or buildings will be flooded due to the subsequent rise in water level. And when the staff does not turn off the power switch of the submersible pump in time after the on-site water is pumped out, it will cause the motor of the submersible pump to be no-load, resulting in waste of electric energy (when the motor rotates no-load for a long time, due to the lack of water cooling, there is also a problem that the motor temperature rises too high and is damaged). Content of the Utility Model

[0004] In order to overcome the drawbacks of existing submersible pumps due to their structural limitations as described in the background, the present utility model provides an integrated prefabricated flood control pumping station mainly used for draining accumulated water in relevant areas. Based on the submersible pump body, it is installed in a casing that can be conveniently carried by hand, which brings convenience for staff to transfer the position of the submersible pump body. It can automatically turn on or off the power supply of the submersible pump body when the accumulated water in the relevant area reaches a certain depth and decreases to a certain depth, bringing convenience to the staff and effectively ensuring timely drainage work. And when the accumulated water in the relevant water area has not been drained completely for a long time, it can prompt the staff by text message, preventing the submersible pump body from being damaged and other situations that may cause the accumulated water in the relevant area to not be drained, and the subsequent water level rise leading to the risk of surrounding equipment or buildings being flooded.

The two normally open contact terminals of the control relay J1 and the two ends of the power input of the submersible pump body M are connected by wires. The inverting input terminal 2 of the operational amplifier K3 at the signal input terminal of the control circuit and the positive electrode of the capacitor C1 at the signal output terminal of the detection circuit are connected by wires.

When the detection head detects water, the signal output terminal outputs power, otherwise it does not output; the short message sending module K4 is a short message alarm module of model IEV3995, which has two power input terminals and six signal input terminals. When the six signal input terminals respectively input low levels, it can send out six short messages stored in advance inside.

[0018] Figure 1 , 2As shown in the figure, this new type is mainly used for draining water in the relevant area. Based on the submersible pump body M, it is installed in the shell 1 that can be conveniently carried by hand. Since the two sides of the upper end of the shell 1 have a "Π"-shaped handle 102, it brings convenience for the staff to carry and transfer the position of the submersible pump body M by hand. Specifically, after the staff arrives at the site, they put the shell 1 into the water, and then turn on the main power switch above the water bank. After the submersible pump body M is powered on and works, it pumps the water at a low place and outputs it to a high place through a hose, etc. After the AC power enters the power input terminal of the power module K1, the power output terminal of the power module K1 outputs a stable DC 12V power supply and enters the power input terminals of the water accumulation detector K2 and the control circuit. When the water level in the relevant area is relatively shallow and does not submerge the detection head of the water accumulation detector K2, the 3rd and 2nd pins of the water accumulation detector K2 do not output power. In this way, the relay J1 will not be powered on and attracted, and the submersible pump body M will not be powered on and work; when the water level in the relevant area is relatively deep and submerges the detection head of the water accumulation detector K2, the 3rd and 2nd pins of the water accumulation detector K2 output power and enter the power input terminal of the relay J1. In this way, the relay J1 will be powered on and attracted to control the power input terminal and the normally open contact terminal to close, and the submersible pump body M will be powered on and work. In actual situations, when there is water accumulation at the site and the relay J1 is powered on and attracted, the high level output from the 3rd pin of the water accumulation detector K2 will also be divided by the adjustable resistor R1 and the resistor R2, and the resistor R3 will step down and limit the current to charge the capacitor C1. In the initial period (such as less than 3 hours; the actual maximum delay time can reach 10 hours, and the time is equal to 1.1×the resistance value of the adjustable resistor R1×the capacitance of the capacitor C1), when the capacitor C1 is not fully charged, the voltage of the high level entering the 2nd pin of the operational amplifier K3 is lower than the voltage of the 12V power supply entering the 3rd pin of the operational amplifier K3 after being divided by the resistor R4 and the resistor R5 (such as 9V). The 6th pin of the operational amplifier K3 outputs a high level, so the short message sending module K4 will not be powered on, and the short message sending module K4 will not send out a short message. After a certain period of time (such as more than 3 hours), when the capacitor C1 is fully charged, the voltage of the high level entering the 2nd pin of the operational amplifier K4 (such as higher than 9V) is higher than the voltage of the 3rd pin. The 6th pin of the operational amplifier K3 outputs a low level and enters the base of the triode Q1. The triode Q1 conducts and the collector outputs a high level and enters the 1st pin of the short message sending module K4. Then the short message sending module K4 is powered on. Since its 2nd and 3rd pins are pre-connected, the short message sending module K4 will send out the first short message stored internally. After the mobile phone of the relevant staff at the remote end receives the short message, they can know in the first time that the water accumulation at the site has not been pumped out completely.Through the above, when the water accumulates to a certain depth and decreases to a certain depth in the relevant area, the power supply of the submersible pump body is automatically turned on or off, which brings convenience to the staff, effectively ensures timely drainage, and when the water in the relevant water area has not been drained completely for a long time, it can prompt the staff by text message to prevent the damage of the submersible pump body and other situations that cause the water in the relevant area cannot be drained, and the subsequent water level rise leads to the risk of surrounding equipment or buildings being flooded (if the water has not been drained completely for a long time, such as the rain has stopped at the scene, it means that the submersible pump body may be damaged, and the staff can go to the scene for inspection and maintenance in time).
