DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Please refer to Figures 1-5 In the embodiment, the metal roof edge waterproof assembly comprises a fixed part 1, the top of the fixed part 1 is provided with a metal roof 2, the right side of the metal roof 2 is provided with a water collecting groove 3, and the outer part of the water collecting groove 3 is provided with an anti-blocking mechanism 4.

[0028] The anti-blocking mechanism 4 comprises a limiting cavity 401, a sliding rod 402, a sliding sleeve 403, a metal filter screen 404, a steel wire pull rope 405, a drive box 406, a transmission wheel 407, a DC motor 408, a winding sleeve 409, a first winding roller 410, a second winding roller 411, a manual pull rope 412 and a pull handle 413, the inside of the water collecting groove 3 is provided with the limiting cavity 401, the inside of the limiting cavity 401 is fixedly provided with the sliding rod 402, the outside of the sliding rod 402 is slidably connected with the sliding sleeve 403, the outside of the sliding sleeve 403 is provided with the steel wire pull rope 405, the top of the metal roof 2 is fixedly provided with the drive box 406, the inside of the drive box 406 is fixedly provided with two transmission wheels 407, the left side of the water collecting groove 3 is provided with the DC motor 408 and the winding sleeve 409, the inside of the winding sleeve 409 is rotatably provided with the first winding roller 410 and the second winding roller 411, the outside of the second winding roller 411 is fixedly provided with the manual pull rope 412, and the bottom of the manual pull rope 412 is fixedly provided with the pull handle 413.

[0029] Specifically, the outside of the steel wire pull rope 405 is provided with a polyurethane protective outer layer. Polyurethane has excellent wear resistance, oil resistance and tear resistance, and also has good weather resistance and chemical resistance, is suitable for application in various industrial environments, can effectively protect the steel wire pull rope 405, prevent the steel wire pull rope 405 from rusting and being corroded, and prolong the service life of the steel wire pull rope 405.

[0030] Specifically, in order to ensure that the metal filter screen plate 404 can move up and down smoothly, the cooperation between the sliding rod 402 and the sliding sleeve 403 is crucial. The sliding sleeve 403 can slide freely on the sliding rod 402, and the sliding rod 402 is embedded in the limiting cavity 401 inside the water collecting groove 3. The inner wall of the limiting cavity 401 is provided with a limiting sliding groove, which not only helps to guide the linear motion of the sliding sleeve 403, but also provides a penetration path for the connecting rod. One end of the connecting rod is fixed with the sliding sleeve 403, and the other end is connected with the metal filter screen plate 404. In this way, when the sliding sleeve 403 moves under force, the metal filter screen plate 404 will also move, realizing effective cleaning of the debris in the water collecting groove 3.

[0031] Specifically, when the user pulls up the handle 413, the manual pull rope 412 begins to pull the second winding roller 411, which rotates in the winding sleeve 409, thereby driving the first winding roller 410 fixedly connected thereto to rotate. Since the top of the steel wire pull rope 405 passes through the winding sleeve 409 and the metal ceiling 2 and is fixedly connected with the first winding roller 410, when the first winding roller 410 rotates, it will begin to wind the steel wire pull rope 405, thereby pulling the sliding sleeve 403 to slide upward along the sliding rod 402. The movement of the sliding sleeve 403 drives the metal filter screen plate 404 fixedly connected thereto to rise until the top of the metal filter screen plate 404 is flush with the top of the water collecting groove 3.

[0032] Specifically, the DC motor 408 in this paper is a high-efficiency small driving device, which is designed to allow manual rotation of the first winding roller 410 in a stopped state. This means that even in the case of unstable power supply or DC motor 408 failure, the user can still manually rotate the first winding roller 410 to pull the steel wire pull rope 405 and raise or lower the metal filter screen plate 404.

[0033] In summary, the metal roof edge waterproof assembly drives the first winding roller 410 by the DC motor 408, thereby pulling the steel wire pull rope 405 to drive the metal filter screen plate 404 to slide upward along the sliding rod 402 until the top of the metal filter screen plate 404 is flush with the top of the water collecting groove 3. At this time, with the help of the rainwater flowing on the surface of the metal ceiling 2, the branches, leaves and other debris accumulated on the metal filter screen plate 404 can be effectively removed, preventing these debris from blocking the water flow passage and ensuring smooth water flow. Avoiding backflow of rainwater to the roof, thereby reducing the risk of leakage and enhancing the effect of the waterproof system.

[0034] And, in addition to being able to automatically control the lifting of the metal filter screen plate 404 by the direct current motor 408, the metal roof edge waterproof assembly also has a manual operation mode, and the user can pull the manual pull rope 412 by pulling the pull handle 413 to make the second winding roller 411 rotate, thereby pulling the steel wire pull rope 405, and also achieving the lifting action of the metal filter screen plate 404 to remove the accumulated objects. The design of the double operation mode not only enhances flexibility, but also ensures that users can still conveniently maintain the waterproof assembly and ensure its normal operation to protect the overall building protection effect in the case of unstable power supply, solves the problem that in windy weather conditions, branches and leaves and other debris are easily blown onto the roof and eventually accumulated in the water collecting groove. These debris not only block the water flow path and reduce the drainage efficiency, but also may cause rainwater to flow back to the roof, increasing the risk of leakage. In addition, due to the height design of the water collecting groove, the cleaning work becomes relatively difficult and needs to be regularly maintained to ensure its normal function. If these accumulated objects are not cleaned in time, the effectiveness of the entire waterproof system may be weakened, thereby affecting the overall protection effect of the building.
