Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, in particular to a high-head drainage device for flood control. Background Art

[0002] In various flood control and drainage fields, such as draining the accumulated water in underground parking lots, draining the water accumulated in relevant areas after floods, etc., generally, self-priming pumps or submersible pumps are used for drainage. Among them, submersible pumps are widely used in actual flood control and drainage because they can be directly put into water, do not require a special working position, are convenient to use, and the motor can be fully water-cooled.

[0003] Although the existing flood control and drainage equipment based on submersible pumps meets the working needs to a certain extent, the power of a single submersible pump is limited, that is, the drainage volume is relatively small. When there is a large amount of accumulated water in the corresponding area and it needs to be drained as soon as possible, then more submersible pumps need to be put into the water to meet the actual working needs. In the above operation mode, since multiple submersible pumps cannot be combined together, the outlet ends of multiple submersible pumps need to be connected to rubber outlet pipes respectively, and when arriving at the site, the power plugs of multiple submersible pumps need to be inserted into power sockets respectively, etc., which will bring certain inconveniences to transportation and on-site use. Content of the Utility Model

[0004] In order to overcome the disadvantages that when using submersible pumps in the existing flood control and drainage work, since multiple submersible pumps are in a split structure, it will bring inconveniences to transportation and on-site use, the utility model provides a high-head drainage device for flood control based on two or more submersible pump bodies, which can conveniently combine multiple submersible pump bodies, make their outlet ends in parallel, bring convenience to transportation, storage and on-site use, and can timely prompt the staff to handle the failure when a corresponding submersible pump has a problem.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

The water outlet pipe of each submersible pump body is equipped with a connecting pipe, and both side ends of the connecting pipe have threads. Between the multiple submersible pump bodies, one side of the connecting pipe of one adjacent submersible pump body and one side of the connecting pipe of another submersible pump body are connected together. Among the multiple submersible pump bodies, a sealing cover is installed on the other side of the connecting pipe of the last submersible pump body, and the other side of the connecting pipe of the first set of submersible pump bodies is connected to the water outlet hose. There are multiple sets of the detection mechanism, the detection circuit, and the solenoid valve respectively. Each submersible pump body is respectively equipped with a set of detection mechanism, detection circuit, and solenoid valve. The detection mechanism is a direct current water flow generator, and multiple sets of detection mechanisms are respectively installed inside the water outlet pipes of multiple submersible pump bodies. The water outlet pipes of multiple sets of submersible pump bodies and the lower ends of multiple sets of solenoid valves are respectively connected, and the upper ends of multiple sets of solenoid valves and the lower ends of multiple connecting pipes are respectively connected. Multiple sets of detection circuits are installed in the component box, and the signal output ends of multiple sets of detection mechanisms and the signal input ends of multiple sets of detection circuits are respectively electrically connected.

[0007] Further, the solenoid valve is a normally closed spool solenoid valve.

[0008] Further, the detection circuit includes a diode, a DC voltage stabilizing module, a relay, and an alarm lamp that are electrically connected. The positive and negative power input ends of the relay and the positive and negative power output ends of the DC voltage stabilizing module are respectively connected. The normally closed contact end of the relay is connected to the positive power input end of the alarm lamp. The negative power input end of the alarm lamp and the negative power output end of the DC voltage stabilizing module are connected. The positive power input end of the DC voltage stabilizing module is connected to the negative pole of the diode.

[0009] Further, multiple fixing rings are annularly distributed on the outer lower side of the fixing seat at the lower end of the submersible pump body. The bottom plate has multiple sets of fixing screw holes from left to right. The spacing distances of multiple submersible pump bodies are installed on the bottom plate through the fixing rings and fixing screw seats.

[0010] Further, the submersible pump body can also adopt a deep well pump, and the submersible pump body can also be horizontally installed on the bottom plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: (1) Based on two or more submersible pump bodies, the present novel installs them on the bottom plate, which can facilitate the combination of multiple submersible pump bodies and make their water outlet ends in parallel, bringing convenience to transportation, storage and on-site use; (2) Multiple sets of detection mechanisms and detection circuits can detect the working performance of multiple submersible pump bodies in real time.

Multiple bolts are respectively screwed into the threads of multiple fixing screw holes 9 through the multiple fixing rings 8 of the multiple submersible pump bodies from left to right, and the three submersible pump bodies are installed on the bottom plate 1 at intervals from left to right. The submersible pump body can also use a deep well pump, and the submersible pump body can also be horizontally installed on the bottom plate. The solenoid valves DC1, DC2, and DC3 are normally closed spool solenoid valves with a power of 2W; the power of the submersible pump bodies M1, M2, and M3 is 2KW; the power supply module E1 is a finished AC 220V to DC 6V switching power supply module; the model of the diode VD1 is 1N4007; the model of the relay J1 is DC6V; the direct current water flow generator M is a finished small 12V water flow type direct current generator; the DC voltage stabilizing module E2 is a DC - DC voltage stabilizing module with an input of 6V - 36V and an output of 6V; the three sets of alarm lamps H are LTE - 5061 small strobe indicating alarm lamps (the emitting colors are red, green, and yellow respectively). Figure 3All components in [the device] are existing mature technologies, and the specific working principles thereof will not be elaborated in this application.

[0018] Figure 1 , 2 As shown in Figure 3, the power input terminals 1 and 2 of the power supply module E1 are respectively connected to the two poles of the AC 220V power supply through wires; one ends of the power switches D1, D2, D3, D4, D5, and D6 are connected to one pole of the AC 220V power supply through wires, and the power output terminals of the power switches D1, D2, D3, D4, D5, and D6 and the other pole of the 220V AC power supply are respectively connected to the power input terminals of the three submersible pump bodies M1, M2, and M3 and the solenoid valves DC1, DC2, and DC3 through wires.

The operating handles of all power switches and the light-emitting surfaces of the alarm lamps are all located outside multiple openings at the front end of the component box.

[0019] Figure 1 , 2As shown in FIGS. 3, this new type is based on three submersible pump bodies, which are installed on the bottom plate 1. Since it is convenient to combine multiple submersible pump bodies and make their water outlet ends in parallel, it brings convenience to transportation, storage and on-site use. During application, the user puts the three submersible pump bodies into the water, and the component box is located on the shore above the water area. After the staff respectively turn on the power switches D1, D2, and D3, the three submersible pump bodies M1, M2, and M3 are powered on and work. After respectively turning on the power switches D4, D5, and D6, the solenoid valves DC1, DC2, and DC3 are powered on and their valve cores open. In this way, the three parallel submersible pump bodies M1, M2, and M3 pump out the water in the relevant area, then output it upward through the three connecting pipes 3, and finally discharge it above the water area through the hose 5 (rubber water outlet pipe) to achieve the drainage purpose (the water is discharged to the drainage area, such as the sewer near the underground parking lot of the community, etc.). After the power module E1 is powered on and works, its pins 3 and 4 output a stable DC 12V power supply and enter the power input ends of the three sets of detection circuits. After the three sets of detection mechanisms and detection circuits are powered on and work, when one or more corresponding submersible pump bodies M1 (M2, M3) work normally and pump out water, the water will flow upward and impact the blades of the corresponding set of water current generators M. The corresponding set of water current generators M generates DC power supply, which is unidirectionally conducted through the corresponding diode VD1 and enters the positive power input end of the DC voltage stabilization module E2 of the corresponding set of detection circuits. The pins 3 and 4 of the corresponding DC voltage stabilization module E2 output a stable DC 6V power supply and enter the power input end of the corresponding relay J1. The corresponding relay J1 is powered on and its control power input end and normally closed contact end are open, and the corresponding alarm light H will not be powered on and work to give an alarm, indicating that the corresponding submersible pump body is working normally. When one or more corresponding submersible pump bodies M1 (M2, M3) work abnormally and do not pump out water, there is no upward water flow to impact the blades of the corresponding set of water current generators M (even if other submersible pump bodies work normally and pump out water, but the water impacts the blades of the corresponding set of water current generators M in the reverse direction. Therefore, due to the reverse cut-off effect of the diode VD1, the DC voltage stabilization module E2 will not be powered on and work, and the relay J1 will not be powered on and attracted. The corresponding alarm light will still be normally powered on and give a prompt). The corresponding set of water current generators M stops generating DC power supply, and the positive power input end of the DC voltage stabilization module E2 of the corresponding set of detection circuits loses power. Subsequently, the power input end of the corresponding relay J1 loses power, the corresponding relay J1 loses power and no longer attracts, its control power input end and normally closed contact end close, and the corresponding alarm light H is powered on and works to give an alarm prompt, indicating that the corresponding submersible pump body is working abnormally. After seeing the corresponding alarm light emit light, the staff can perform corresponding disposal on the corresponding one or more submersible pump bodies and eliminate the faults (such as temporarily turning off the power supply of one of the submersible pump bodies and the corresponding solenoid valve to prevent the motor from continuously powering on and the fault from expanding when the motor fails).
