[0003] Currently, when submersible pumps are installed on a channel slope, they are mostly lifted to the installation location by a crane. When the working environment is affected or the operating radius of the crane is insufficient, the installation of the submersible pump and its accessories requires underwater operations, which cannot meet the installation location requirements of the submersible pump and its accessories, affecting the installation and disassembly efficiency. In addition, when the submersible pump fails, it is adversely affected by the limited operating radius of the crane, resulting in cumbersome procedures for the rapid installation and maintenance of the submersible pump during operation.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0022] like Figure 1 to Figure 3 As shown, the present embodiment provides a submersible pump quick installation and disassembly device, which is arranged on a channel slope 1 and includes a basic steel plate 2 laid on the channel slope 1. The basic steel plate 2 is hoisted onto the channel slope 1 by a crane. A plurality of basic beams 3 are fixedly arranged on the basic steel plate 2, and the basic beams 3 are welded to the basic steel plate 2. Tracks 4 are arranged on the basic steel plate 2 and the basic beams 3 along the inclination direction of the channel slope 1, serving as a quick installation track for a submersible pump 6. A cross bar 5 is arranged at the bottom of the track 4, and the submersible pump 6 is limited by the cross bar 5 to ensure that it stops moving after moving to a specified position. A submersible pump 6 is slidably installed on the track 4, and a pulley 7 matching the track 4 is arranged below the submersible pump 6. The submersible pump 6 slides on the track 4 through the pulley 7. The model of the submersible pump 6 is 500QW3300-15. A filter screen cover 21 is arranged at the water inlet of the submersible pump 6 for filtering impurities in the water, and is located 2.2m below the water surface of the water delivery channel to ensure the safe water level and flow rate of the pipeline water supply.

[0023] A fixed channel steel 8 is fixedly arranged on the horizontal ground at the top of the channel slope 1, and the fixed channel steel 8 is fixedly connected to the base steel plate 2. The base steel plate 2 is welded to the fixed channel steel 8, and the base steel plate 2 is fixed and limited by the deadweight of the base steel plate 2 and the fixed channel steel 8. The fixed channel steel 8 is provided with two and is fixed to the horizontal ground by threaded steel or bolts. The fixed channel steel 8 can also fix the base steel plate 2 by other existing structures or devices. An electric fall chain 9 is installed on the fixed channel steel 8, and the electric fall chain 9 is connected to the submersible pump 6 by a sliding chain 10. The electric fall chain 9 drives the submersible pump 6 to be lifted or dropped along the track 4 by the sliding chain 10 to realize rapid installation and disassembly. A plurality of support columns 11 are fixedly arranged on the base steel plate 2, and the support columns 11 are arranged in an H shape and the bottom is welded at On the foundation steel plate 2, an inclined water-conveying steel pipe 12 is arranged on the support column 11, and the inclined water-conveying steel pipe 12 is connected to the submersible pump 6. The inclined water-conveying steel pipe 12 is parallel to the track 4, and the inclined water-conveying steel pipe 12 is supported and fixed by the support column 11. A plurality of hanging ears 20 are fixedly arranged on the inclined water-conveying steel pipe 12, and the hanging ears 20 are welded and fixedly connected to the support column 11 or bolted and fixed to the corresponding support column 11. The hanging ears 20 can be arranged on both sides, below or above the inclined water-conveying steel pipe 12. On the one hand, it is convenient to hoist the inclined water-conveying steel pipe 12. On the other hand, the inclined water-conveying steel pipe 12 can be fixed by the hanging ears 20 and the horizontal bars or vertical bars of the support column 11 to be suitable for different working conditions. The inclined water-conveying steel pipe 12 is fixed by welding or bolting to avoid the influence of vibration on the inclined water-conveying steel pipe 12.

[0024] One end of the inclined water supply steel pipe 12 is connected to the submersible pump 6 through a reducing elbow 13, and the other end is connected to a bend 14. The direction of the inclined water supply steel pipe 12 is changed by the bend 14. In this embodiment, the bend 14 adopts a 22.5° bend, and the reducing elbow 13 adopts a reducing elbow from 400mm to 800mm. The bend 14 is connected to a horizontal water supply steel pipe 15, and the horizontal water supply steel pipe 15 is parallel to the top road surface of the channel slope 1.

The expansion joint 17 is connected to an electric butterfly valve 18, and the electric butterfly valve 18 is connected to a water supply pipeline 19. The expansion joint 17 is used to compensate for the expansion and contraction deformation of the pipeline to reduce the influence of vibration on the pipeline. The check valve 16 and the electric butterfly valve 18 are used to control the flow rate and prevent the occurrence of water hammer effect. The water supply pipeline 19 and the horizontal water supply steel pipe 15 are supported and installed by support columns 11.

[0025] When the channel is damaged and water supply is interrupted due to extreme natural disasters, the upstream water is first cut off to lower the water level at the channel slope 1 and block the damaged point at the same time. Then, the foundation steel plate 2 is hoisted on the channel slope 1. The foundation crossbeam 3 and the support column 11 are welded on the foundation steel plate 2, and the track 4 is provided. Since the foundation steel plate 2 is a whole piece of steel plate, it can be hoisted when the crane operation radius is short, and it is avoided that the submersible pump 6 cannot be directly hoisted to the designated installation position when the crane operation radius is limited. The staff needs to make adjustments, and then fix the fixed channel steel 8 on the road surface where the road surface and the channel slope 1 are connected, and weld the fixed channel steel 8 to the foundation steel plate 2, and then install the electric fall chain 9 at the position of the fixed channel steel 8, hoist the submersible pump 6 to the upstream of the track 4, connect the electric fall chain 9 and the submersible pump 6 through the sliding chain 10, and the electric fall chain 9 releases the sliding chain 10, and then the submersible pump 6 slides along the track 4 under the action of its own gravity into a position below the water level, and is limited by the cross bar 5 after reaching the installation position, and stops moving.

[0026] Then install the reducer elbow 13 and hoist the inclined water supply steel pipe 12, connect the elbow 14 and the horizontal water supply steel pipe 15, the inclined water supply steel pipe 12 and the horizontal water supply steel pipe 15 are flange-connected with the corresponding elbow 14 and the reducer elbow 13, so as to facilitate quick disassembly and assembly, the horizontal water supply steel pipe 15 is connected with the check valve 16, the expansion joint 17, the electric butterfly valve 18, and the water supply pipeline 19 in sequence, the water supply pipeline 19 crosses the damaged point to realize long-distance water supply, restore the water level near the channel slope 1, and immerse the submersible pump 6 in the water surface.

[0027] The submersible pump 6 is lifted and lowered along the track 4 by the electric fall chain 9, so that the submersible pump 6 can be quickly installed and removed. When the submersible pump 6 fails, the submersible pump 6 can be lifted and quickly removed from the water surface by the electric fall chain 9, thereby ensuring the emergency water supply restoration of the channel section where the water supply is interrupted due to natural disasters.
