BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Hereinafter, the present utility model will be described in more detail based on embodiments and with reference to the drawings.

[0019] Among them:

[0020] Figure 1 shows a schematic structural view of the present utility model;

[0021] In the drawings, the same components are denoted by the same reference numerals. The drawings are not drawn to actual scale.

[0022] Reference numerals:

[0023] 1 - fixing cylinder, 2 - connecting plate, 3 - scraping plate, 4 - pull rod, 5 - driving handle, 6 - first buckle, 7 - second buckle, 8 - tension spring, 9 - through hole, 10 - ear plate. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will further illustrate the present utility model with reference to the drawings.

[0025] The present utility model provides a device for cleaning sundries in a water stop joint, such as Figure 1As shown, it comprises a fixed cylinder 1 and a connecting plate 2 matching the inner diameter of the water stop joint, the connecting plate 2 is connected to the bottom of the fixed cylinder 1, the outer edge of the bottom of the connecting plate 2 is connected to a plurality of scrapers 3 extending in the vertical direction, a pull rod 4 passing through the connecting plate 2 is arranged in the fixed cylinder 1, one end of the pull rod 4 is respectively connected to each scraper 3 through a plurality of connecting pieces, and the other end of the pull rod 4 is connected to a driving handle 5 for its up and down displacement;

[0026] It should be noted that the connecting disk 2 is placed into the water stop joint or taken out of the water stop joint through the fixing tube 1, and the pull rod 4 located in the fixing tube 1 is connected to the scraper 3 on the edge of the connecting disk 2, and the pull rod 4 is driven by the handle 5 to move up and down so that the multiple scrapers 3 on the connecting disk 2 are expanded or retracted. For example, during the same-body casting construction of the water stop joint, the cleaning device provided in this embodiment is sequentially placed into the water stop joint, and the scraper 3 on the connecting disk 2 is first expanded to scrape the inner wall of the water stop joint, and the multiple scrapers 3 on the connecting disk 2 are retracted during the process of taking out the water stop joint. Compared with the cleaning tools such as hammers or shovels used in traditional cleaning operations, it is not only more convenient and quick to use, and improves the cleaning efficiency, but also can avoid damage to the inner wall of the water stop joint, and reduce the risk of subsequent leakage.

[0027] Specifically, if Figure 1 As shown, three scrapers 3 are arranged at the bottom of the connection disk 2, and the three scrapers 3 are evenly spaced along the outer edge of the connection disk 2. At the same time, a first buckle 6 movably connected to the connection disk 2 is arranged on the top of each scraper 3, so that the scraper 3 can be turned along the first buckle 6. The diameter of the connection disk 2 is slightly smaller than the inner diameter of the water stop joint. The connection disk 2 is extended into the water stop joint through the fixed tube 1. At this time, the pull rod 4 is moved downward to turn the baffle toward the direction close to the inner wall of the water stop joint until it conflicts with it. The fixed tube 1 can be rotated to scrape the water stop joint. After the scraping operation is completed, the pull rod 4 is moved upward to turn the baffle toward the direction away from the inner wall of the water stop joint to avoid damage to it when it is taken out of the water stop joint, and then enter the next water stop joint to repeat the scraping operation;

[0028] In one embodiment, Figure 1 As shown, a second buckle ring 7 movably connected to a connecting member is provided on one side of the scraper 3 close to the pull rod 4, and the connecting member is a tension spring 8, that is, one end of the tension spring 8 is connected to the pull rod 4, and the other end is connected to the second buckle ring 7 on the scraper 3, that is, under the initial tension of the tension spring 8 on the second buckle ring 7, the scraper 3 can be tilted and extended, so as to protect the water stop joint when being inserted into or taken out of the water stop joint;

[0029] In one embodiment, the connection plate 2 is provided with a through hole 9 along its center. The pull rod 4 passes through the through hole 9 and is connected to the scraping plate 3. The fixed cylinder 1 is of an annular structure, and the bottom ring of the fixed cylinder 1 is welded to the connection plate 2. The center of the connection plate 2 is located on the axis of the fixed cylinder 1. The scraping plate 3 is made of a steel plate, and a layer of zinc is plated on the surface of the steel plate. The thickness of the scraping plate 3 is 1 mm. That is, the fixed cylinder 1 and the connection plate 2 are concentrically arranged, which is convenient for the two to rotate synchronously to facilitate the scraping operation. At the same time, the bottom ring of the fixed cylinder 1 is welded to the surface of the connection plate 2 to ensure the stability of the connection between the two. At the same time, the galvanized scraping plate 3 prevents it from rusting;

[0030] In one embodiment, as Figure 1 shown, the driving handle 5 includes an integrated straight section and an arc section. The arc section is fixedly connected to the pull rod 4. The straight section of the driving handle 5 is hinged to the fixed cylinder 1. Ear plates 10 are provided on both the fixed cylinder 1 and the straight section of the driving handle 5 and are hinged together. That is, the driving handle 5 is connected to both the fixed cylinder 1 and the pull rod 4, making the entire device integrated. At the same time, the straight section of the driving handle 5 and the fixed cylinder 1 are hinged together through the protruding ear plates 10. That is, the hinge point serves as the rotation center, so that when the driving handle 5 is lifted upward or pressed downward, the pull rod 4 connected to the driving handle 5 moves up and down, thereby controlling the posture of the scraping plate 3;
