Description

Technical Field

[0001] This utility model relates to the field of building exterior wall repair technology, and in particular to a waterproof repair device for building exterior walls. Background Technology

[0002] With the acceleration of urbanization, a large number of buildings have sprung up. The exterior walls of these buildings are exposed to the natural environment for a long time, and are subjected to erosion from various factors such as wind, sun, rain, temperature changes and air pollutants. Rainwater infiltration is an extremely serious problem for building exterior walls. Once the waterproofing of the exterior wall is defective, water will seep into the interior of the wall, which may cause the wall materials to become damp, moldy and deteriorate, reduce the strength and thermal insulation performance of the wall, and in severe cases, even affect the structural stability of the building.

[0003] In light of the above, it should be noted that Chinese patent application number CN2022110329255 discloses a robot for repairing exterior wall insulation and waterproofing layers. This robot uses a remotely controlled flying robot to spray and repair exterior walls with waterproofing defects and gaps. However, during actual use, the flying robot's own propulsion to maintain balance and movement causes the surrounding airflow to accelerate, which is not conducive to spraying and repairing defective areas of the exterior wall. In addition, simple spraying repair can easily result in low adhesion between materials, gaps, and low waterproofing repair effect on the exterior wall.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof repair device for building exterior walls to solve the problems mentioned above.

[0013] The beneficial effects of this utility model are:

[0014] (1) This utility model uses a servo motor-driven spiral stirring paddle to achieve rapid and uniform mixing of repair materials in the paint mixing tank. The materials form a circulating flow trajectory during the stirring process, ensuring sufficient and uniform mixing and improving the quality of the repair material. The design of the collar and scraper effectively prevents the materials from sticking to the return cylinder cover and the paint mixing tank, ensuring the fluidity of the materials between the two and avoiding blockage. At the same time, it also accelerates the mixing of materials in this area and further improves the mixing efficiency.

[0015] (2) This utility model uses a rotary cylinder and a discharge valve to make the repair material easy to discharge as needed and transport it to the inside of the extended brush holder through a pump and pipeline system. This not only simplifies the operation process but also improves the conveying efficiency of the repair material. The adjustable extension length between the extended brush holder and the slide bar, as well as the clamping and fixing method of the industrial roller brush, enable the device to adapt to the needs of exterior wall repair at different heights. At the same time, the intermittent start design of the controller and the pump makes the operation simpler and more flexible, meeting the needs of different repair tasks. The entire repair process is realized through mechanization and automation, which greatly reduces the labor intensity of the operator and improves the work efficiency. The precise delivery and spraying control of the repair material ensures the stability and consistency of the repair quality. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 7As shown, this embodiment is a waterproof repair device for building exterior walls, including a stabilizing base plate 1, a paint mixing tank 2 on the top of the stabilizing base plate 1, a cap 3 on the top of the paint mixing tank 2, an extension brush rack 4 and an external valve 5 on the outer wall of the paint mixing tank 2, an inner mixing rack 6 inside the paint mixing tank 2, a material pump 103 and a servo motor 104 inside the stabilizing base plate 1, and a central shaft 606 and a spiral stirring paddle 604 at the bottom of the inner mixing rack 6 that are connected to the servo motor 104.

[0027] According to the needs of waterproofing repair of the building's exterior walls, the repair materials are poured into the paint mixing tank 2 according to the mixing ratio, and the cap 3 is placed on top. The device is started, and the servo motor 104 drives the central shaft 606 to rotate through the coupling. The central shaft 606 drives the spiral agitator 604 to rotate, causing the raw materials inside the paint mixing tank 2 to be gradually mixed. Under the push of the spiral agitator 604, the mixed raw materials are all pushed downwards. The downward-flowing raw materials are continuously pushed, causing some raw materials to flow upwards along the space between the paint mixing tank 2 and the return shroud 602, until they enter the paint mixing tank 2 through the top of the return shroud 602. There, they are further stirred and pushed downwards by the spiral agitator 604, causing the raw materials to form a circulating flow trajectory inside the paint mixing tank 2.

[0028] The top of the stabilizing base plate 1 is provided with an inner frame 101 embedded in the bottom of the paint mixing tank 2. The top center of the inner frame 101 is provided with a ring-shaped material collection trough 102. The material pump 103 is embedded on the side of the material collection trough 102, and the servo motor 104 is embedded in the bottom center of the stabilizing base plate 1.

[0029] The outer wall of the paint mixing tank 2 is provided with a clamp 201 that is connected to the extension brush holder 4. The inner wall of the bottom of the paint mixing tank 2 is provided with a conical disc 203. The bottom center of the conical disc 203 is provided with a ring-shaped unloading valve 202. A rotary cylinder is provided on the side of the unloading valve 202.

[0030] A guide ring 601 is provided at the bottom edge of the inner mixing frame 6, and a return cylinder cover 602 is provided inside the guide ring 601. The top of the central shaft 606 is sleeved at the bottom center of the inner mixing frame 6, and a collar 605 is sleeved on the bottom shaft of the central shaft 606. A scraper 603 is provided on the outer wall of the collar 605, extending between the return cylinder cover 602 and the paint mixing tank 2, and the top of the scraper 603 is slidably sleeved with the guide ring 601.

[0031] During the flow of raw materials along the circulation trajectory, the collar 605 rotates along the central shaft 606, thereby driving the scraper 603 to move between the return cylinder cover 602 and the paint mixing tank 2, scraping off the raw materials adhering to the return cylinder cover 602 and the paint mixing tank 2, ensuring the flowability of the raw materials between the two, avoiding blockage, and accelerating the mixing of raw materials in this area.

[0032] The spiral agitator 604 is sleeved on the top outer shaft of the central shaft 606. The spiral agitator 604 has a structure that is wider at the top and narrower at the bottom. After the raw materials are continuously mixed and shaped in the paint mixing tank 2, the repair material is obtained. The rotary cylinder is activated as needed. The rotary cylinder drives the discharge valve 202 to rotate through the fastener, so that the bottom of the paint mixing tank 2 and the collection tank 102 are kept in communication. Under the influence of the weight of the repair material accumulated inside the paint mixing tank 2, some of the repair material near the discharge valve 202 falls directly into the collection tank 102. The pump 103 is started at the same time. The pump 103 is connected to the collection tank 102 and the external valve 5 through the pipeline. The external valve 5 is connected to the extension brush holder 4 pipeline through the external telescopic hose. Accordingly, the pump 103 extracts the repair material inside the paint mixing tank 2 and transports it to the extension brush holder 4 along the pipeline.

[0033] Example 2: A waterproof repair device for building exterior walls in this example includes an extension brush holder 4 with a clamp 404 at the top and a spray tube 402 at the bottom of the outer periphery of the clamp 404.

[0034] The top of the extension brush holder 4 is slidably sleeved with a slide rod 401, and a clamp 404 is set on the top of the slide rod 401. A rotating sleeve 403 is provided on the outer peripheral wall of the top of the slide rod 401 and threadedly sleeved with the clamp 404. The spray tube 402 is embedded in the top of the slide rod 401, and a telescopic hose that penetrates the slide rod 401 and the extension brush holder 4 is provided at the bottom of the spray tube 402.

[0035] According to the needs of building exterior wall repair, the paint mixing bucket 2 is transported to the area near the exterior wall to be repaired by a mobile trolley. The user holds the extension brush holder 4 and adjusts the extension length between the extension brush holder 4 and the slide bar 401 according to the height difference between the exterior wall and the user. The extension brush holder 4 has a chamber with a telescopic hose inside. During the extension of the slide bar 401, the telescopic hose is pulled, stretched and contracted. Under the pressure of the pump 103, the repair material is forced to be transported into the spray tube 402 and sprayed onto the surface of the industrial roller brush on the clamp 404.

[0036] It should be noted that the industrial roller brush is a tool used for painting and repairing exterior walls. The handle is inserted into the clamp 404, which drives the rotating sleeve 403 to rotate, causing the rotating sleeve 403 to be threadedly connected to the outer wall of the clamp 404, and the clamp 404 is continuously limited until the industrial roller brush is clamped and fixed. The user starts the material pump 103 intermittently according to the controller set on the frame of the extension brush holder 4, spraying a certain amount of repair material onto the surface of the industrial roller brush. Under the operation of the user, the exterior wall of the building is waterproofed and repaired, which saves time and effort.

[0037] Combining Embodiments 1 and 2, this utility model achieves rapid and uniform mixing of repair materials in the paint mixing tank 2 through a spiral stirring paddle 604 driven by a servo motor 104, forming a circulating flow trajectory to ensure thorough and uniform mixing, thereby improving the quality of the repair materials. The collar 605 and scraper 603 are designed to prevent material adhesion, ensure fluidity, avoid blockage, and accelerate mixing. The rotary cylinder and unloading valve 202 work together to simplify the unloading and conveying process of the repair materials, improving conveying efficiency. The adjustable length of the extended brush holder 4 and slide bar 401, along with the industrial roller brush clamping and fixing, adapts to repair needs at different heights. The controller and the material pump 103 start intermittently, making operation simple and flexible. The overall system is mechanized and automated, reducing labor intensity, improving work efficiency, and ensuring stable and consistent repair quality.
