Description

An ecological water intake device for an inclined internal pump truck

Technical Field

The invention relates to a water intake device for a drainage and irrigation station, in particular to an inclined ecological water intake device for an internal pump truck.

Background Art

Irrigation and drainage stations are basic water conservancy facilities in industrial and agricultural production. They are built near rivers and use motors or diesel engines to pump water from the river into the main canal to irrigate farmland. Since the water-facing slope of the irrigation and drainage station dam is long, the water intake pipe of the water intake device needs to be extended to the river to smoothly take water. The water intake methods of traditional irrigation and drainage stations mainly include pump truck water intake (see Figure 11), submersible water intake (see Figure 12), and pipe, rail and pump truck combined water intake (see Figure 13).

1. The main disadvantages of the pump truck water intake method are: 1) The construction is highly seasonal, difficult to construct, and costly; 2) There are many water outlet couplings. When the water level at the outer river station fluctuates greatly, it is necessary to always pay attention to the equipment being submerged, which is inconvenient to manage; 3) Vacuum extraction is required before starting, which is troublesome to operate and has a high failure rate; 4) Since all the equipment is installed on the pump truck, there is a lot of vibration during operation.

2. The main disadvantages of the submersible water intake method are: 1) The construction is highly seasonal, hydraulic construction is difficult, and the cost is high; 2) It requires underwater engineering, and cofferdams need to be built during construction, which takes a long construction period; 3) The coupling of the pump needs to be installed on-site. Since the coupling requires high precision, it takes a lot of time to adjust, and sometimes rework is required, and the installation and commissioning time is long; 4) The pipes and tracks are separated, and the construction is difficult; 5) The project excavation volume is large, the original ecological water area is destroyed, and the project is easily silted up after completion; 6) The management of the project is difficult in the later stage, and nearly 30% of the projects are scrapped due to siltation.

3. Although the combined pipe, rail and pump truck water intake method is convenient in construction, short in period, and not affected by seasons, easy to manage, and not prone to siltation after completion, its main disadvantages are: 1) The pump truck is a cross-pipe design, and the water intake point of the pump mouth is relatively high, which is not suitable for low water level water intake; 2) The pump group is installed externally, and cables, wire ropes and other equipment are exposed outside the water intake pipe, which is not easy to manage. Cables and wire ropes are often stolen, and the drainage and irrigation station cannot work.

Summary of the invention

The purpose of the present invention is to provide an inclined internal pump truck ecological water intake device which adopts an internal pump truck to slide and install a water pump in a pipeline, does not need to set up a separate pump truck track, automatically couples the butterfly seal to prevent leakage, does not expose cables, wire ropes and other facilities, does not need to build a cofferdam, and is not affected by the season; so as to solve the problem that the existing drainage and irrigation stations need to build a cofferdam, and the motors, cables and wire ropes are placed outside the pipeline and are easy to be stolen.

The technical solution of the present invention is:

An inclined internal pump truck ecological water intake device, comprising a pipeline 3, a water outlet pipe 13 and a water pump, wherein the pipeline 3 and the water outlet pipe 13 are connected; the characteristic is that the water pump is slidably installed in the middle and lower part of the pipeline 3 through the inner wall of the pipeline 3;

The water pump is equipped with a pump truck, which consists of a submersible water pump 6 and a submersible motor 7. The submersible motor 7 is fixedly mounted on the end of the submersible water pump 6. The pump truck consists of a pump truck A4 and a pump truck B5. The pump truck A4 is mounted on the submersible water pump 6, and the pump truck B5 is mounted on the submersible motor 7.

The traction device is composed of a pulley frame 11, a steering pulley 12 and a wire rope 17. The steering pulley 12 is installed on the pulley frame 11. The steering pulley 12 is equipped with the wire rope 11. One end of the wire rope 11 is connected to the water pump, and the other end of the wire rope is connected to the overhead crane.

The pump truck A is composed of a pump wheel A, a front fixing bolt, a pump truck frame A, a wheel support plate A and a pin shaft A. The pump truck frame A is a circular ring structure, and its inner diameter is 0.5-1 mm larger than the outer diameter of the water inlet of the submersible water pump. The pump truck frame A is made with a wheel support plate A, and the pump wheel A is installed on the wheel support plate A through the pin shaft A. A front fixing bolt is installed between every two wheel support plates A on the pump truck frame A.

The submersible water pump and the submersible motor can move up and down in the pipeline through the pump wheel A of the pump truck A and the pump wheel B of the pump truck B, and can be lifted away from the opening at the upper end of the pipeline by a traveling crane.

The advantages of the present invention are:

The inclined internal pump truck ecological water intake device has the characteristics of no need to build a cofferdam and the motor is installed in an internal manner. Through the cantilever installation of the pipeline, there is no need to build a cofferdam, which ensures the original ecological landform of the outer river station water intake construction site; the motor, water pump, cable and wire rope and other facilities are all set in the pipeline, which not only reduces the height of the motor and the water intake, but also reduces the cantilever length of the pipeline, enhances the rigidity of the overall equipment, and no longer needs to consider the drawbacks of insufficient overall rigidity caused by too long cantilever. At the same time, it is also suitable for irrigation station dry season and low water level water intake; and because of its safe and reliable work and low failure rate, it is easy to realize network control and improve the level of modern management.

DETAILED DESCRIPTION

The inclined internal pump truck ecological water intake device comprises a pipeline 3, a water outlet pipe 13 and a water pump. The pipeline 3 is connected to the water outlet pipe 13. The pipeline 3 is obliquely installed on the anchor 9 on the ground below the pump room 1. The lower end of the pipeline 3 extends into the water so as to take water from the river. The lower end of the pipeline 3 extending into the river is fixed with an anti-rotation plate 18. The upper end of the pipeline 3 is made with an opening, and a pipeline opening cover 14 is installed on the opening. The pipeline opening cover 14 and the opening are sealed by a sealing flange 15; a traction device is installed in the opening of the pipeline 3, and the water pump is placed in the pipeline 3 through the opening; the traction device is composed of a pulley frame 11, a steering pulley 12 and a wire rope 17. The steering pulley 12 is installed on the pulley frame 11, and the steering pulley 12 is equipped with a wire rope 17. One end of the wire rope 17 is connected to the water pump, and the other end of the wire rope 17 is connected to the traveling crane 2 on the top of the pump room 1. The model of the traveling crane 2 is LX-10. The water pump is slidably installed in the middle and lower part of the pipeline 3 through the inner wall of the pipeline 3. Further, the water pump is placed in the lower end of the pipeline 3 extending into the water through a traction device.

The water pump is equipped with a pump truck, which consists of a submersible water pump 6 and a submersible motor 7. The submersible motor 7 is fixedly mounted on the end of the submersible water pump 6; the pump truck consists of a pump truck A4 and a pump truck B5. The pump truck A4 is mounted on the submersible water pump 6, and the pump truck B5 is mounted on the submersible motor 7. The pump truck A4 is composed of a pump wheel A4-1, a front fixing bolt 4-2, a pump truck frame A4-3, a wheel support plate A4-4 and a pin A4-5. The pump truck frame A4-3 is a circular ring structure, and its inner diameter is 0.5-1 mm larger than the outer diameter of the water inlet of the submersible water pump 6. A wheel support plate A4-4 is made on the pump truck frame A4-3, and a pump wheel A4-1 is installed on the wheel support plate A4-4 through a pin A4-5. The pump wheel A4-1 can slide along the inner wall of the pipeline 3 in the pipeline 3. A front fixing bolt 4-2 is installed between every two wheel support plates A4-4 on the pump truck frame A4-3, and the front fixing bolt 4-2 is used to fasten the pump truck A4 to the submersible water pump 6. The pump truck B5 is composed of a pump wheel B5-1, a rear fixing bolt 5-2, a pump truck frame B5-3, a wheel support plate B5-4 and a pin shaft B5-5. The pump truck frame B5-3 is a circular ring structure, and its inner diameter is 0.5-1 mm larger than the outer diameter of the submersible motor 7. A wheel support plate B5-4 is made on the pump truck frame B5-3, and a pump wheel B5-1 is installed on the wheel support plate B5-4 through the pin shaft B5-5. The pump wheel B5-1 can slide along the inner wall of the pipeline 3 in the pipeline 3. A rear fixing bolt 5-2 is installed between every two wheel support plates B5-4 on the pump truck frame B5-3, and the rear fixing bolt 5-2 is used to fasten the pump truck B5 to the submersible motor 7.

The water pump can be moved up and down in the pipeline 3 by the wire rope 17 and the crane 2 through the pump truck A4 and the pump truck B5, and can be lifted away from the opening at the upper end of the pipeline 3 by the crane 2.

The diameter of the vertices of the four pump wheels A4-1 on the pump truck A4 of the above-mentioned submersible water pump 6 is 4-5 mm smaller than the inner diameter of the pipeline 3. Similarly, the diameter of the vertices of the four pump wheels B5-1 on the pump truck B5 of the submersible motor 7 is 4-5 mm smaller than the inner diameter of the pipeline 3. Its function is to prevent welding and manufacturing burrs on the inner wall of the pipeline 3 from jamming the movement of the pump truck.

The installation process of the inclined internal pump truck ecological water intake device is as follows: remove the pipe opening cover 14 of the upper end opening of the pipe 3, fix the pump truck A4 with the submersible water pump 6 as a whole through the front fixing bolts 4-2, and fix the pump truck B5 with the submersible motor 7 as a whole through the rear fixing bolts 5-2, and then use the traveling crane 2 to lift the pump truck unit into the opening at the upper end of the pipe 3, slowly lower the pump truck unit into the opening of the pipe 3, and then connect the wire rope 17 on the traction device with the submersible motor 7, and pass the wire rope 17 through the steering pulley 12 to connect the traveling crane 2, and gradually move the unit down along the inner wall of the pipe 3 to the bottom through the traction of the wire rope 17 and the traveling crane 2, and fasten it with the anti-rotation plate 18, and the installation of the water intake device is completed. When the water pump moves down to the lower end of the pipe 3, remove the wire rope 17 connected to the overhead crane 2 and lock it on the pulley frame 11, then pass the cable on the submersible motor 7 through the cable lead-out fixing column 19 to pass through the pipe 3 and fix it on the cable lead-out fixing column 19. Then seal the pipe opening cover 14, and then you can start pumping irrigation. If you need to repair the water pump, you can take it out according to the reverse process of the above installation.

The inclined internal pump truck ecological water intake device has good strength and can be cantilevered a certain distance into the water, so there is no need to build a cofferdam, the construction is relatively simple, and the construction process will not damage the original ecological water area. Since the motor of the water intake device is installed in a hidden manner, the submersible motor 7 and the submersible water pump 6 are both arranged in the pipeline 3, which reduces the height of the water pump and the motor, and is 1-1.5 meters lower than the installation height of the existing water pump and motor, so that water can be taken normally in the shallow water period. Since the water intake of the water pump is reduced by 1-1.5 meters, compared with the existing similar design scheme using pipe rail integration, the cantilever length of the pipeline 3 can be reduced by 2.5-4 meters, that is, if the pipeline of the existing design scheme is to be cantilevered 5-8 meters, the cantilever length of the pipeline of the present application scheme only needs 2-3 meters, so that under the same engineering environment and water intake conditions, the cantilever length of the pipeline 3 is reduced by 2.5-4 meters, and there is no need to use inclined pull technology. The construction is not affected by the season, and it can be constructed all year round, the engineering cycle is short, and a large amount of engineering funds can be saved.

On the other hand, since there are no external cables, the loss of cables, wire ropes and other materials can be prevented, which solves many problems existing in drainage and irrigation stations, such as the inconvenience of maintaining pump truck units, the need to build cofferdams and external motors, and meets the needs of water conservancy irrigation.
