Description

Flood prevention and emergency water pump

Technical field

The utility model relates to a water pump for flood control and emergency rescue which can flexibly move and draw water.

Background technique

At present, water conservancy projects and flood control and drought relief projects in vast areas of our country are to build fixed pumping stations, and various types of water pumps are installed in the stations to realize pumping and drainage. However, the occasions for flood control and drought relief are far more than the above-mentioned fixed pumping stations. Sometimes some areas without pumping stations suddenly need emergency drainage or water delivery, and the fixed pumping stations will not be able to play a role. At this time, only some small and flexible water pumps that can be lifted by people can be used to temporarily pump water on site. Their disadvantages are that the power is too small, mainly because the pump flow rate is small, usually below 600m3/h, which cannot meet the needs of flood control and drought relief. The amount of water pumped depends on the land demand. Moreover, many sites have no power supply, and the electric pump cannot be used. Sometimes a fire truck is used for water supply in drought-resistant situations, but it only acts as a mobile water tank, and its main function is not designed for flood control and drought relief. Moreover, the vehicle fire pump is characterized by small flow, high lift, and constant pressure, which is not suitable for flood control, drought relief and emergency situations.

Contents of the invention

The purpose of the utility model is to provide a mobile and flexible water pump for flood control and emergency rescue.

The technical solution to solve the above problems is: the utility model is composed of an automobile chassis 1, a water outlet hose 2, a hydraulic lifting winch 3, a support 4, a supporting door frame 6, and a hydraulic pump 8, and the water outlet hose 2 is set on the hydraulic pump 8 On the outlet of the hydraulic pump 8; one end of the hydraulic pump 8 is placed on the support 4, and the other end is hoisted on the supporting door frame 6, and is fixedly connected with one end of the steel wire rope 5; the other end of the steel wire rope 5 is wound on the hydraulic lifting winch 3; the fixed pulley 7 and The supporting mast 6 is fixedly connected; the hydraulic lifting winch 3 and the supporting mast 6 are both fixedly connected with the support 4; the support 4 is placed on the automobile chassis 1 and is fixedly connected with the automobile chassis 1. In this way, a mobile hydraulic pump station is formed, which can go to work in various places at any time.

The water pump for flood control and emergency rescue of the utility model is flexible and can go to the site where drainage needs to be pumped and drained at any time.

Detailed ways

As shown in accompanying drawing 1, the utility model is made up of automobile chassis 1, water outlet hose 2, hydraulic lifting winch 3, bearing 4, support door frame 6, hydraulic pump 8. The water outlet hose 2 is set on the outlet of the hydraulic pump 8; one end of the hydraulic pump 8 is placed on the support 4, the other end is hoisted on the supporting door frame 6, and one end of the steel wire rope 5 is fixedly connected; the other end of the steel wire rope 5 is wound on the hydraulic lift. On the heavy winch 3; the fixed pulley 7 is fixedly connected with the supporting mast 6; the hydraulic lifting winch 3 and the supporting mast 6 are both fixedly connected with the support 4; the support 4 is placed on the automobile chassis 1, and is fixedly connected with the automobile chassis 1 . In this way, both the pump system and the lifting system are placed on the car, which can be driven to the area where water needs to be pumped at any time. The hydraulic pump can be pumped by putting the hydraulic pump into the water through the lifting system composed of hydraulic lifting winch, fixed pulley, steel wire rope and supporting gantry. The working status is shown in Figure 2. Lift the pump and put it away after use.

As shown in accompanying drawing 3, hydraulic pump 8 is made up of water suction pipe 9, guide vane body 10, impeller 11, transmission shaft 12, coupling 13, hydraulic motor 14, overflow cylinder 15, outlet pipe 16. The water suction pipe 9 is fixedly connected with the guide vane body 10; the guide vane body 10 is fixedly connected with the flow tube 15; the flow tube 15 is fixedly connected with the outlet pipe 16; the hydraulic motor 14 is fixedly connected with the flow tube 15; The transmission shaft 12 and the shaft extension of the hydraulic motor 14 are fixedly connected; the impeller 11 is sleeved on the transmission shaft 12 . The water suction pipe, guide vane body and impeller are collectively referred to as the hydraulic components of the pump, which adopts a large-flow high-efficiency hydraulic model. When the pump works, the hydraulic motor 14 drives the impeller 11 to rotate through the shaft coupling 13 and the transmission shaft 12 to realize the pumping function. Using this kind of hydraulic pump to pump water does not require a power source, and the flow rate is from 450m3/h to 4000m3/h, which is far greater than the flow rate of small pumps, and can meet the temporary large water pumping demand.
