Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a rainwater drainage mechanism for building construction. Background Technology
[0002] Building construction refers to the process of gradually building a building or structure by using building materials and a series of construction techniques and operations according to design drawings and technical specifications. Building construction is a complex system engineering project that involves the coordination and cooperation of multiple professional fields and multiple stages.
[0003] A search revealed a rainwater drainage mechanism for building construction (publication number CN213836970U), comprising a fixed base and a sludge hopper. The fixed base has two symmetrically arranged fastening blocks on its outer sidewall. A through hole is formed at the center of the inner bottom wall of the fixed base, and a sludge inlet pipe is fixedly installed therein. A filter screen is fixedly connected inside the through hole on the bottom surface of the fixed base. A filter cover is fixedly connected to the top of the sludge inlet pipe, and a waterproof sleeve is fitted onto the outer sidewall of the sludge inlet pipe. This device, by setting up the fixed base, sludge hopper, and waterproof sleeve, forms an inclined angled area, which allows heavier debris such as mud particles in rainwater to settle and facilitates cleaning. Rainwater drainage is only initiated when a certain rainfall amount is reached. Simultaneously, the filter cover and filter screen prevent drainage blockage while filtering rainwater, thus ensuring efficient drainage.
[0004] Based on the aforementioned patent, by setting up a fixed base, a sludge hopper, and a waterproof sleeve, the three components together form an inclined angled area, which will settle heavier debris such as mud particles in rainwater sewage and facilitate the cleaning of debris. Rainwater drainage will only be carried out when a certain amount of rainfall is reached. At the same time, due to the setting of a filter cover and filter screen, rainwater sewage is filtered while preventing drainage blockage, thereby affecting the rainwater drainage efficiency. However, when the above-mentioned device is used, after a long period of use, a certain amount of debris will often accumulate on the screen, which may cause the screen to become blocked and thus affect the filtration effect of the screen.
[0005] In response to this technical problem, this application proposes a rainwater drainage mechanism for building construction. Utility Model Content

[0023] 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.
[0024] Reference Figures 1-2 An embodiment of this utility model provides a construction rainwater drainage mechanism, including a water intake plate 1, a filter box 2 fixedly connected to the front end of the water intake plate 1, a support frame 5 fixedly connected to the top of the filter box 2, a waterproof cover 7 fixedly connected to the top left side of the support frame 5, a motor 6 fixedly connected to the left end of the support frame 5, a threaded rod 8 fixedly connected to the drive end of the motor 6, a slider 9 fixedly connected to the outer wall of the threaded rod 8, a waterproof electric push rod 10 fixedly connected to the bottom end of the slider 9, a push plate 11 fixedly connected to the top end of the push plate 11 on the drive end of the waterproof electric push rod 10, the right end of the threaded rod 8 rotatably connected to the inner wall of the right end of the support frame 5, the top end of the slider 9 slidably connected to the inner wall of the bottom end of the support frame 5, a connecting box 12 fixedly connected to the right end of the filter box 2, a collection box 13 fixedly connected to the bottom end of the connecting box 12, a drawer 14 slidably connected to the inner wall of the collection box 13, and a handle 15 fixedly connected to the right end of the drawer 14 on the left end.
[0025] Specifically, when cleaning debris from filter screen 3, motor 6 is first started, which drives threaded rod 8 to rotate, causing slider 9 to move to the right. The movement of slider 9 pushes push plate 11 on waterproof electric push rod 10 to the right, causing debris from filter screen 3 to be pushed to the right and ultimately enter collection box 13 through connecting box 12. For easier cleaning next time, waterproof electric push rod 10 is started to move push plate 11 upwards, then threaded rod 8 is rotated in the opposite direction to move slider 9 to the left, causing push plate 11 to move to the left as well, preparing for another cleaning of debris. Debris in collection box 13 can be collected through drawer 14. Pulling handle 15 moves drawer 14 to the right, making it easy to remove drawer 14 for cleaning.
[0026] Reference Figure 1 and Figure 3 The top of the water inlet plate 1 is provided with multiple inlet channels 16, the filter screen 3 is fixedly connected to the inner wall of the filter box 2, the bottom of the filter box 2 is fixedly connected to the water outlet pipe 4, the outer wall of the water outlet pipe 4 is fixedly connected to the valve 19, the bottom of the water outlet pipe 4 is fixedly connected to the water collection tank 17, and the left end of the water collection tank 17 is fixedly connected to the drain pipe 18.
[0027] Specifically, water flows into the filter box 2 at a specific angle through the water inlet plate 1. The water inlet groove 16 on the water inlet plate 1 guides the water flow, thereby improving drainage efficiency. The filter screen 3 intercepts impurities in the water flow, and the filtered clean water is discharged through the outlet pipe 4, ensuring that the outlet pipe 4 is not blocked by impurities. After opening the valve 19, the water in the outlet pipe 4 is collected by the water collection tank 17. When drainage is required, the water can be discharged through the drain pipe 18.
[0028] Working principle: First, the water flow from the water inlet plate 1 flows into the filter box 2 through the angle of the water inlet plate 1. The water is guided by the diversion groove 16 on the water inlet plate 1, which improves the drainage efficiency. The filter screen 3 intercepts impurities in the water flow. The filtered water can be discharged through the outlet pipe 4, which can prevent the outlet pipe 4 from being blocked by impurities. By opening the valve 19, the water flow in the outlet pipe 4 is collected by the water collection tank 17. When it is time to discharge, it can be discharged through the drain pipe 18. Second, when it is time to clean the impurities on the filter screen 3, the motor 6 is started, which drives the threaded rod 8 to rotate, thereby driving the slider 9 to move to the right. Move 9 to the right, thereby moving the push plate 11 on the waterproof electric push rod 10 to the right, which in turn moves the debris on the filter screen 3 to the right, allowing the debris to enter the collection box 13 through the connecting box 12. By activating the waterproof electric push rod 10, the push plate 11 is moved upward. Then, by rotating the threaded rod 8 in the opposite direction, the slider 9 is moved to the left, which in turn moves the push plate 11 on the waterproof electric push rod 10 to the left, making it easier to clean the debris next time. The debris in the collection box 13 is collected in the drawer 14. By pulling the handle 15, the drawer 14 is moved to the right, allowing the drawer 14 to be removed for easy cleaning of the debris inside.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
