[0002] Submersible pumps are important equipment for deep well water extraction. They are mainly divided into clean water submersible pumps and sewage submersible pumps (also known as submersible sewage pumps). When in use, the entire unit submerges into the water to extract groundwater to the surface. It can also be used in water extraction projects such as rivers, reservoirs, and canals. It is a commonly used equipment for domestic water use, mine rescue, industrial cooling, farmland irrigation, seawater lifting, and ship loading.

[0003] At present, when lifting a submersible pump in a container (for example, a lifting well, a pool, or a well), manual lifting or electric hoist lifting is generally adopted. Although electric lifting operation can save labor and avoid safety risks compared with manual lifting operation, the existing electric hoist lifting requires the use of a gantry, which is not only more complex in structure and occupies a large area, but also cannot adjust the retractable position and angle of the submersible pump according to the needs of the user, which makes it very inconvenient for the user to use the submersible pump and has great limitations.

[0021] Example

[0022] See also Figures 1 to 3 As shown, the present embodiment provides a rotatable submersible pump lifting device with a linear guide, comprising a vertically arranged rotatable linear guide 1, a slider 2 being slidably connected to the linear guide 1, a water pump fixing seat 3 being fixed on the slider 2, and a horizontally rotatable cantilever 4 being provided at the top of the linear guide 1, a pulley 5 being provided at the top of the cantilever 4, a winch 6 being provided in the middle of the cantilever 4, a steel wire rope 7 being provided on the pulley 5, one end of the steel wire rope 7 being used to be connected to a submersible pump 11, and the other end of the steel wire rope 7 being connected to the winch 6 after passing through the pulley 5.

[0023] In this embodiment, a slewing bearing 8 is fixedly provided on the top of the linear guide 1, the cantilever 4 is fixed to the top of the inner ring 8-1 of the slewing bearing, and the bottom of the outer ring 8-2 of the slewing bearing is fixedly connected to the top of the linear guide 1. Through the slewing bearing 8, the cantilever 4 can rotate 360 ​​degrees around the linear guide 1, thereby driving the submersible pump 11 to rotate 360 ​​degrees, and then the position and angle of the submersible pump can be conveniently adjusted according to the needs of the user.

[0024] The slewing bearing 8 in this embodiment is preferably a gearless slewing bearing to avoid adverse effects on the lifting and lowering of the wire rope 7.

[0025] In addition, in this embodiment, an arcuate fixing seat 9 is provided at the bottom of the linear guide 1, a rotating member 10 is provided at the protruding portion of the arcuate fixing seat 9, and the bottom of the linear guide 1 is fixedly connected to the rotating portion of the rotating member 10. The rotating member 10 can be a servo motor, and the rotating portion is the motor shaft or a coupling connected to the motor shaft.

[0026] In addition, in this embodiment, the slider 2 is U-shaped, and the water pump fixing seat 3 is fixed on the back 2-1 of the slider. The slider 2 and the water pump fixing seat 3 can be welded and fixed into an integrated structure. Figure 4 shown.

[0027] In addition, the winch 6 can be an electric winch, a manual winch, or an integrated electric and manual winch. Preferably, it is an integrated electric and manual winch with a self-locking mechanism, so that it can be lifted electrically under normal conditions and lifted manually in a power outage, and can self-lock to stop the lifting of the wire rope 7 when it reaches the lifting position.

[0028] It should be noted that the submersible pump 11 described in the present invention can be a clean water submersible pump or a sewage submersible pump.

[0029] The method of using the rotatable submersible pump lifting device with a linear guide provided by the utility model is as follows:

[0030] See also Figure 5 As shown, firstly, the linear guide rail 1 is installed in the pool or well 12. The specific implementation method of this embodiment is: the two side wings 9-1 of the arched fixing seat 9 at the bottom of the linear guide rail 1 are fixedly connected to the bottom of the pool or well 12 (the studs can be used for fixing); then the submersible pump 11 is fixed to the water pump fixing seat 3 on the ground, and then the lower end of the wire rope 7 is fixedly connected to the submersible pump 11, thereby completing the installation of the submersible pump lifting device of the utility model;

[0031] Then, by releasing the winch 6, the steel wire rope 7, the submersible pump 11 and the slider 2 are lowered along the linear guide rail 1. When the submersible pump 11 is lowered to the required depth, the winch 6 is locked to stop the steel wire rope 7 from descending, and the submersible pump 11 can be fixed at the required depth in the pool or well 12. After the submersible pump 11 is fixed to the required depth, if the angle of the submersible pump 11 needs to be adjusted, the linear guide rail 1 can be driven to rotate by driving the rotating member 10 at the bottom of the linear guide rail 1 to rotate, so that the angle adjustment of the submersible pump 11 can be achieved.

[0032] When the submersible pump 11 needs to be lifted from the pool or well 12, the wire rope 7 is driven up by the winding winch 6, so that the submersible pump 11 and the slider 2 can be driven up along the linear guide 1. When the submersible pump 11 rises to the required height, the winch 6 is locked, and then the linear guide 1 is driven to rotate by driving the rotating part 10 at the bottom of the linear guide 1 to change the angle of the submersible pump 11 to the required position.

[0033] From the above, it can be seen that the submersible pump lifting device provided by the utility model has the advantages of simple structure, small footprint, easy installation and use, good safety, etc. compared with the traditional gantry lifting device; and, through the combined use of the rotatable linear guide 1 and the horizontally rotatable cantilever 4, not only can the submersible pump be rotated 360 degrees, but the position and angle of the submersible pump can be conveniently adjusted according to the needs of the user, which can significantly improve work efficiency and reduce the labor intensity of the staff, and the linear guide 1 plays a supporting role and a guiding role in the lifting of the submersible pump 11, which can effectively ensure the stability and safety of the lifting of the submersible pump 11; therefore, the utility model has obvious practical value.

[0034] Finally, it is necessary to point out that the above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be covered within the protection scope of the utility model.
