[0002] With the rapid development of urban construction and underground engineering, waterproofing of underground structures such as basements, underground garages, and underground utility tunnels is of paramount importance.

[0003] In the traditional process of applying waterproof coatings, a roller is usually used to repeatedly dip the waterproof coating onto the surface to be coated. This method is inefficient, and it is difficult to control the amount of material used by hand. The coating drips heavily during the application process, which not only wastes material but also contaminates the work surface and is difficult to clean.

[0004] A search revealed that self-priming roller brush devices already exist in the prior art, but these self-priming roller brushes still have the following problems:

[0005] 1. The length of the roller is fixed, so when there are different painting scenarios, you can only change to different sized roller brushes, which is not convenient to use.

[0006] 2. As a consumable, the roller of a roller brush cannot be quickly disassembled and replaced, making the replacement process troublesome. Utility Model Content

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] like Figure 1 As shown, this utility model proposes a waterproof coating device for underground structure walls, including a cylinder 1 with liquid absorption and supply functions. A three-way pipe 2 is detachably connected to one end of the cylinder 1, and a hollow fixing frame 3 is connected to the other end of the three-way pipe 2. The fixing frame 3 is used for material supply and support. The left end of a first roller 8 is connected to the fixing frame 3. The outer peripheral walls of the first roller 8 and the second roller 9 are provided with brush bristles for applying waterproof coating. The right end of the first roller 8 is detachably connected to the second roller 9, forming an expandable connection structure. This expandable structure allows this utility model to adapt to different construction scenarios.

[0034] In some embodiments, the middle of the three-way tube 2 is fixedly connected with two handles 11 parallel to the first roller 8. The handles 11 can make the painting process easier after extending the length of the roller.

[0035] Both the first roller 8 and the second roller 9 have cavities that extend through their axial direction. These cavities are connected to the inside of the cylinder 1 through a fixing frame 3 and a three-way pipe 2. The cavity structure forms a conveying channel for the waterproof coating, thereby conveying the waterproof coating inside the cylinder 1 to the inside of the first roller 8 and the second roller 9.

[0036] In some embodiments, such as Figure 3 As shown, the right end of the first roller 8 is inserted into the left end of the second roller 9; a spring-loaded second hook 91 is provided on the side wall of the insertion part of the second roller 9, and a second slot 81 is provided on the side wall of the insertion part of the first roller 8 corresponding to the position of the second hook 91, and the second hook 91 engages with the second slot 81; the method of fixing by engaging the second hook 91 with the second slot 81 makes the connection process of the first roller 8 and the second roller 9 simple and smooth, and a stable connection can be achieved simply by aligning and inserting; at least one pair of second slots 81 and second hooks 91 are provided symmetrically on the top and bottom, which makes the connection more stable and less likely to fall off during use compared to a single pair of engaging structures.

[0037] In some embodiments, such as Figure 3 , Figure 4 As shown, a pull hook 92 is fixedly connected to the bottom of the second hook 91. The entire device also includes a pull rod 10 disposed inside the second roller 9. A third slot 102 is provided at the left end of the pull rod 10 corresponding to the position of the pull hook 92, and the third slot 102 engages with the pull hook 92. With this configuration, when the pull rod 10 moves to the right, it can drive the second hook 91 to retract and move into the second roller 9 through the pull hook 92, thereby disengaging the second slot 81 from the second hook 91. A sealing cap 93 with a central hole is fixedly connected to the right end of the second roller 9. The pull rod 10 passes through the central hole on the sealing cap 93 and forms a sliding connection with the second roller 9. In use, the second roller 9 can be quickly disengaged from the first roller 8 simply by pulling the pull rod 10 axially to the right.

[0038] The pull rod 10 has a hollow structure, allowing the right side of the central tube 41 to extend into it, enabling the waterproof coating conveyed within the central tube 41 to flow into the pull rod 10, thus acting as a liquid guide. Leakage holes on the side wall of the pull rod 10 allow the waterproof coating to be more evenly distributed onto the inner wall of the roller. A leak-proof ring 104 is fixedly connected to the pull rod 10 inside the second roller 9 near the sealing cap 93. The leak-proof ring 104 fits into the inner wall of the second roller 9, forming a sliding seal to prevent the waterproof coating from leaking out from the interface between the pull rod 10 and the sealing cap 93. Furthermore, the double-point contact between the leak-proof ring 104 and the end of the pull rod 10 ensures better coaxiality between the pull rod 10 and the second roller 9, improving structural stability. A return spring 12 is fitted onto the pull rod 10, with one end connected to the leak-proof ring 104 and the other end connected to the sealing cap 93. The return spring 12 allows the pull rod 10 to automatically return to its original position and also prevents accidental rightward movement of the pull rod 10, which could cause the second roller 9 to detach.

[0039] In some embodiments, such as Figure 2 As shown, the upper end of the fixing frame 3 is connected to a hollow support member 4. The support member 4 includes a central tube 41 and a screw plate 42 at the end. The central tube 41 has a leakage hole inside the first roller 8 to evenly distribute the waterproof coating to the inner wall of the first roller 8. A rotating member 5 is sleeved on the central tube 41, and the left end of the first roller 8 is inserted into the rotating member 5. The screw plate 42 can serve as a handle during the connection between the fixing frame 3 and the support member 4, and can also provide axial physical restraint for the rotating member 5. A liquid-proof cover 6 is slidably sleeved on the central tube 41. The liquid-proof cover 6 is engaged with the rotating member 5 to seal its open side and prevent the waterproof coating from leaking out. A limiting nut 7 is also included. The limiting nut 7 is located on the right side of the liquid-proof cover 6 and is threadedly connected to the central tube 41. The limiting nut 7 is used to provide axial physical restraint for the rotating member 5 and the liquid-proof cover 6.

[0040] The rotating component 5 has a spring-loaded first hook 51 on its side wall. The first roller 8 has a first slot 82 on the side wall of the part of the rotating component 5 that receives the first hook 51. The first hook 51 engages with the first slot 82. This engagement of the first hook 51 with the first slot 82 enables the quick assembly and disassembly of the first roller 8, solving the problem of cumbersome replacement process.

[0041] How to use:

[0042] Installation of the first roller 8:

[0043] Insert the left end of the first roller 8 onto the rotating part 5, and align it so that the first hook 51 engages with the first slot 82.

[0044] Disassembly of the first roller 8:

[0045] Press the first hook 51 with your hand towards the inside of the first roller 8 while pulling to the right to disengage the first hook 51 from the first slot 82 and remove the first roller 8.

[0046] Installation of the second roller 9:

[0047] Insert the left end of the second roller 9 into the left end of the first roller 8, and align the second slot 81 with the second hook 91 to engage.

[0048] Disassembly of the second roller 9:

[0049] Pull the lever 10 to the right to disengage the second slot 81 from the second hook 91, and then remove the second roller 9.

[0050] Additionally: When using the first roller 8 alone, a sealing cap needs to be installed on the right side of the first roller 8 to prevent the waterproof coating from leaking out.
