Abstract
Description
Technical Field
[0001] This utility model relates to the field of maintenance equipment, and in particular to a water pump safety maintenance vehicle for pumping stations. Background Technology
[0002] During operation, water pumps in pumping stations can easily suck garbage into the pump inlet, causing blockage or jamming in the impeller. This reduces the pump's lifting capacity and causes abnormal noise and vibration.
[0003] To minimize the impact of debris on the normal operation of submersible sewage pumps, the pump's suction inlet and impeller need to be cleaned regularly. This type of periodic cleaning and maintenance typically requires using lifting equipment to hoist the pump to approximately 30 centimeters off the ground. Workers must then crouch beside the pump and reach into the inlet to clean it. Due to the lack of necessary safety precautions, this method of operation poses certain safety hazards.

[0023] Reference Figure 1-3 This embodiment provides a water pump safety maintenance vehicle for a pumping station, including a horizontally arranged base plate 1. In this embodiment, the base plate 1 is welded together from multiple intersecting I-beams. Furthermore, in order to improve the stability of the water pump safety maintenance vehicle, reinforcing ribs are welded on both sides of the I-beams, which can significantly improve safety performance.
[0024] A support plate 2 is welded onto the base plate 1. In this embodiment, the support plate 2 is made of steel plate. Multiple circular inspection ports 3 of varying diameters are provided on the support plate 2. In this embodiment, three inspection ports 3 are provided, each with a different diameter. During water pump maintenance, the water pump's suction inlet side is placed on the inspection port 3. By using multiple inspection ports 3 on a single plate, multiple water pumps can be maintained simultaneously, and the vehicle can accommodate water pumps of different sizes, thus improving the applicability of the water pump maintenance vehicle.
[0025] In this embodiment, the maximum diameter of the inspection port 3 is smaller than the distance between two adjacent I-beams, so that the inspection port will not cross the I-beams and affect maintenance.
[0026] To improve the stability of the water pump during maintenance, an inverted frustum-shaped limiting plate 4 is installed on each maintenance port 3. The limiting plate 4 is open and communicates with the maintenance port 3. The diameter of the bottom of the limiting plate 4 is larger than the diameter of the corresponding maintenance port 3, and the diameter of the top of the limiting plate 4 is larger than the diameter of the bottom, making the entire limiting plate 3 funnel-shaped. This design is because the water pump's suction inlet is also funnel-shaped, so it can fit snugly against the water pump during maintenance, ensuring the stability of the water pump and improving maintenance safety.
[0027] In this embodiment, the inverted frustum-shaped limiting plate 4 has an inclination angle of 45°, and a rubber anti-slip layer is attached to its inner wall, which can improve safety performance.
[0028] In this embodiment, multiple rollers 5 are installed at the bottom of the support plate 2, and the rollers 5 are arranged in the track 6. For easy movement, a drive device is connected to the rollers 5. In this embodiment, the drive device includes a motor 71, the output shaft of which is connected to a geared motor 72. The output shaft of the geared motor 72 is connected to a drive wheel 74 via a belt 73. The drive wheel 74 is fixed to a connecting rod 75, which connects two rollers 5. Thus, the motor 71 drives the geared motor 72 to rotate, which in turn drives the drive wheel 74 to rotate via the belt 73. Finally, the drive wheel 74 drives the connecting rod 75 to rotate, thereby rotating the rollers 5.
[0029] In this embodiment, handrails 8 are installed on both sides of the support plate 2, which facilitates the maintenance workers to get on and off the maintenance vehicle.
[0030] In this embodiment, a ladder 9 is provided on one side of the support plate 2, and the ladder 9 is 50cm-80cm away from the center of the inspection port 3.
[0031] In this embodiment, to facilitate the maintenance of multiple water pumps, a slider (not shown in the figure) is connected to the bottom of the escalator 9. The slider is slidably connected to the slide rail 10. By pushing the escalator 9 to move on the slide rail 10, it can reach different maintenance ports 3, thereby allowing maintenance of the top of the water pumps.
[0032] This safety maintenance vehicle features multiple maintenance ports 3 of varying sizes on a support plate 2, with flared openings on each port 3. This allows water pumps of different sizes to be maintained at their corresponding maintenance ports 3. Additionally, rollers 5 are installed at the bottom for easy movement to a safe area for stable maintenance, thus increasing operational safety. The entire device has a simple structure and significant effectiveness.
[0033] The above description is merely an embodiment of this utility model and does not limit the scope of protection of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the scope of protection of this utility model.
