Description

Technical Field

[0001] The utility model relates to a water collection well maintenance structure of a pump station, belonging to the technical field of water conservancy and hydropower engineering. Background Art

[0002] As an integral part of the pump station structure, the water collection well of a pump station generally consists of the water collection well structure itself and facilities such as the water intake pipe inside the well. In the actual operation and management of the water collection well, in order to facilitate the inspection and maintenance of the structure and facilities inside the well, steel ladders are often pre-buried in the inner wall of the vertical shaft for maintenance personnel to climb up and down to the maintenance area for work. However, this method has the following limitations:

[0003] (1) The maintenance personnel have a small operating radius and it is difficult for the operation range to cover the entire water collection well section, resulting in ineffective maintenance of inaccessible parts;

[0004] (2) Every time the operator enters the well for maintenance, he or she must climb up and down the steel ladder, which not only consumes the maintenance personnel's physical strength but also poses a major safety hazard;

[0005] (3) After the maintenance personnel arrive at the work surface, they need to tie a safety rope on the steel ladder before they can work. For the maintenance personnel, the work is difficult and inefficient. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a pump station water collection well maintenance structure.

[0007] The utility model is achieved through the following technical solutions:

[0023] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0024] like Figures 1 to 5As shown, a pump station water collection well maintenance structure described in the present invention includes a water collection well 1 and a maintenance platform 4. One or more water intake pipes 2 are arranged side by side in the longitudinal direction of the water collection well 1. A plurality of guide rails 3 are arranged side by side on the wall of the water collection well 1, and the guide rails 3 are arranged in the longitudinal direction of the water collection well 1. The maintenance platform 4 is located in the water collection well 1 and is slidably connected to the guide rails 3. A avoidance hole 41 is provided on the maintenance platform 4 at a position corresponding to the water intake pipe 2. The bottom of the maintenance platform 4 is connected to the inner wall of the water collection well 1 through a lifting drive mechanism. When in use, after the maintenance personnel stand on the maintenance platform 4, the lifting drive mechanism drives the maintenance platform 4 to descend along the guide rails 3 in the water collection well 1 to the required depth. When the maintenance of the water collection well 1 is completed, the lifting drive mechanism drives the maintenance platform 4 to rise along the guide rails 3 to the wellhead of the water collection well 1, so that the maintenance personnel standing on the maintenance platform 4 can walk out of the water collection well 1. Since the maintenance platform 4 can basically cover the entire cross-section of the water collection well 1, the maintenance personnel standing on the maintenance platform 4 have a large operating radius, ensuring that all parts of the water collection well 1 can be effectively maintained; the maintenance platform 4 is driven up and down along the guide rail 3 by the lifting drive mechanism to transport the maintenance personnel, which can allow the maintenance personnel to fully maintain their physical strength and reduce the safety risks of maintenance personnel entering and exiting the water collection well 1; the maintenance personnel stand on the maintenance platform 4 to inspect and maintain the water collection well 1, the operation is less difficult, and it helps to improve work efficiency.

[0025] The maintenance platform 4 is slidably connected to the guide rails 3 on the wall of the water collection well 1 through sliders 5.

[0026] The inspection platform 4 is circular and comprises a plurality of sector-shaped panels 40. Adjacent sectors 40 are connected by two connecting assemblies 42, with avoidance holes 41 defined at the joints between the two adjacent sectors 40. The inspection platform 4 is assembled from the plurality of sector-shaped panels 40, with avoidance holes 41 defined at the joints between the two adjacent sectors 40. This allows for assembly and disassembly of the inspection platform 4 as needed, while also preventing interference between the inspection platform 4 and the water intake pipe 2.

[0027] The connecting assembly 42 includes two connecting plates 420, which are respectively located on the upper and lower sides of the fan-shaped plate 40. The ends of the two connecting plates 420 are connected together by bolts 421 and nuts 422, and the bolts 421 located at both ends of the connecting plate 420 correspondingly pass through the two adjacent fan-shaped plates 40.

[0028] The sector plate 40 is made of a patterned steel plate, so that the sector plate 40 has a certain anti-slip function.

[0029] The sector plate 40 is provided with a steel lifting ring 43. It is convenient to adopt a crane to lift the sector plate 40, so as to facilitate the assembly and disassembly of the inspection platform 4.

[0030] The lifting drive mechanism includes a rack 6 and a drive motor. The rack 6 is provided on the wall of the water collection well 1 and arranged longitudinally along the water collection well 1. The drive motor is mounted on the bottom of the maintenance platform 4 via a motor base 8. A gear 7 is mounted on the output shaft of the drive motor, and the gear 7 is meshed with the rack 6. When in use, the drive motor can rotate forward and reverse.

[0031] The driving motor is a brake motor. The driving motor is a brake motor. The brake motor stops rotating when the power is cut off, so that the maintenance platform 4 remains at a desired position and prevents the maintenance platform 4 from falling, thereby improving safety.

[0032] The working principle or use process of the pump station water collection well maintenance structure described in the utility model is as follows:

[0033] After the maintenance personnel stand on the maintenance platform 4, the brake motor rotates forward. Since the gear 7 on the brake motor output shaft is engaged with the rack 6, the maintenance platform 4 is driven to descend along the guide rail 3 to the required depth. The maintenance personnel on the maintenance platform 4 can then begin to inspect and maintain the water collection well 1. After completing the inspection and maintenance work on the water collection well 1, the brake motor rotates in the reverse direction, driving the maintenance platform 4 to rise along the guide rail 3 to the wellhead of the water collection well 1.
