Description

Technical Field

[0001] This utility model relates to the field of water pump unit technology, and in particular to a cleaning tool for the expansion joint of a water pump unit. Background Technology

[0002] Expansion joints, also known as expansion joints or compensators, are primarily used to absorb stress caused by thermal expansion and contraction, vibration, or displacement in pipelines, protecting pump bodies and piping systems. Maintaining the cleanliness of expansion joints is crucial. Cleaned expansion joints can effectively absorb vibrations during pump start-up, shutdown, or operation, while the presence of dirt weakens their vibration-damping effect, leading to increased pipeline swaying or noise and reduced service life. Furthermore, dirt can enter the sliding or corrugated parts of the expansion joint, increasing mechanical wear and potentially damaging its sealing performance. Traditional cleaning methods, due to the large size and high position of expansion joints, require manual cleaning using climbing tools, resulting in low efficiency and limitations imposed by site constraints. While some methods use support poles, these only clean the side walls of the expansion joint, leaving the top uncleaned due to the inability to apply downward force. Clearly, existing cleaning tools are insufficient for cleaning expansion joints. Utility Model Content

[0024] like Figure 1-8 As shown in this embodiment, a cleaning tool for a water pump unit expansion joint includes a support rod 1 and a pressing component disposed above the support rod 1. The support rod 1 is connected to the pressing component through a limiting component. The pressing component includes two arc-shaped plates 2 arranged symmetrically in parallel front and rear. The inner ends of the two arc-shaped plates 2 are connected by a connecting column 3, and their outer ends are connected by a reciprocating mechanism. Arc-shaped grooves 4 are symmetrically provided on the side walls of the two arc-shaped plates 2 along their arc direction. A movable seat 5 is movably engaged between the two arc-shaped plates 2. The left and right ends of the front / rear side walls of the movable seat 5 are respectively provided with locking shafts 6 that are engaged in the corresponding arc-shaped grooves 4. A cleaning plate 7 connected to the movable seat 5 is provided below the arc-shaped plates 2. A cleaning cloth 8 is covered on the bottom of the cleaning plate 7. Connecting ears 9 are provided on the left and right ends of the surface of the movable seat 5. The left connecting ear 9 is connected to the handle 11 via a pull rope 10, and the right connecting ear 9 cooperates with the reciprocating mechanism.

[0025] Optionally, the reciprocating mechanism includes fixed rings 12 symmetrically arranged on the inner walls of two arc-shaped plates 2. The inner ends of the two fixed rings 12 are provided with end caps 13. A bobbin wheel 14 is provided between the two end caps 13. The bobbin wheel 14 passes through the end cap 13 on the corresponding side and extends into the fixed ring 12 on the corresponding side through the limiting post 15 located at the center of its front and rear ends. A coil spring 16 is provided in each of the two fixed rings 12. The inner end of the coil spring 16 is connected to the limiting post 15 on the corresponding side, and its outer end is connected to the inner end of the fixed ring 12. An elastic rope 17 is fixedly wound on the bobbin wheel 14, and the outer end of the elastic rope 17 is tied to the connecting ear 9 on the right side.

[0026] Optionally, the limiting component includes a T-shaped tube 18, the horizontal section of which is movably sleeved on the connecting post 3. On the rear side wall of the connecting post 3, a plurality of serrations 19 connected to the arc plate 2 are evenly provided along its circumference. On the inner wall of the rear end of the horizontal section of the T-shaped tube 18, a plurality of tooth grooves 20 that mesh with the serrations 19 are evenly provided along its circumference. At the front end of the horizontal section of the T-shaped tube 18, an elastic clip 21 is provided that is engaged with the connecting post 3. The vertical section of the T-shaped tube 18 is connected to the upper end of the support rod 1.

[0027] Optionally, the cleaning plate 7 has an upwardly protruding arc shape in the middle. The arc shape of the cleaning plate 7 allows it to fit more closely to the side wall of the telescopic joint, increasing the contact area of ​​the cleaning cloth 8 and improving cleaning efficiency.

[0028] Optionally, the cleaning plate 7 is movably connected to the movable seat 5. An arc-shaped retaining strip 22 is provided at the center of the surface of the cleaning plate 7 along its arc length. An arc-shaped retaining groove 23 is provided at the bottom of the movable seat 5 corresponding to the arc-shaped retaining strip 22. A limiting pin 24 is provided on the side wall of the movable seat 5, passing through the arc-shaped retaining groove 23 of the movable seat 5 and connecting to the arc-shaped retaining strip 22 of the cleaning plate 7. This movable arrangement of the cleaning plate 7 and the movable seat 5 facilitates cleaning of the cleaning cloth 8. During cleaning, simply pull out the limiting pin 24, then push the cleaning plate 7 to misalign it with the movable seat 5, causing the arc-shaped retaining strip 22 to continuously exit from the arc-shaped retaining groove 23, allowing the cleaning plate 7 to be removed for cleaning—simple and quick.

[0029] Optionally, pulleys 25 are fitted onto each of the pivots 6 of the movable seat 5, and a limiting groove 26 is provided around the center of the pulley 25 to engage with the arc-shaped groove 4. The pulleys 25 can further improve the stability of the movable seat 5 during movement, making it smoother.

[0030] Before use, this device allows adjustment of the angle between the lower pressure member and the support rod 1 according to the height of the expansion joint, improving operational convenience and facilitating cleaning work under varying construction conditions. During adjustment, first remove the elastic clamp 21 and move the T-tube 18 laterally, separating the grooves 20 of the T-tube 18 from the serrations 19 of the connecting column 3. Then, rotate the lower pressure member to adjust the angle. After adjustment, reset the elastic clamp 21 to lock the angle between the lower pressure member and the support rod 1.

[0031] When using this device, the support rod 1 can be held with both hands, and the lower pressure member can be placed on the upper part of the telescopic joint, hooking it onto the telescopic joint. Once the cleaning cloth 8 is against the side wall of the telescopic joint, one hand can hold the support rod 1, and the other hand can grasp the handle 11 and pull downwards. The handle 11, through the pull rope 10 and connecting lug 9, pulls the moving seat 5, which in turn moves along the arc-shaped groove 4 within the two arc-shaped plates 2 via the locking pins 6 on both sides. During movement, the lower pressure member forces the cleaning plate 7 against the side wall of the telescopic joint, thus generating downward pressure on the cleaning cloth 8, which helps to clean the top of the telescopic joint. As the moving seat 5 moves, the elastic rope 17 is continuously pulled outwards from the I-beam wheel 14, and as the I-beam wheel 14 rotates, it continuously compresses the coil springs 16 on both sides, generating deformation force. When the movable seat 5 moves to the inner ends of the two arc-shaped plates 2, the handle 11 is released. At this time, under the action of the restoring deformation force, the two coil springs 16 drive the I-beam wheel 14 to reverse, thereby resetting the elastic rope 17 and moving the movable seat 5 to the outer end of the arc-shaped plate 2. Its structure is reasonably designed and easy to operate. It allows for on-site cleaning of the expansion joint without the need for climbing tools, effectively applying pressure to the side walls of the expansion joint, especially the top, efficiently and quickly cleaning away dirt. The cleaning effect is significant, greatly improving worker efficiency and solving problems existing in current technology.
