Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of house drainage devices, in particular to a roof anti-blocking drainage device. Background Art
[0002] The drainage performance of a house is an important indicator to measure the quality of the house. Rainwater is collected through the roof and the height difference is used to gather the rainwater in one place. It is then discharged to a designated location through drainage facilities. Since few people go up to clean the roof, especially for bungalows in the woods when encountering heavy rain, the existing drainage device has a simple structure and a single function. Its inner hole diameter and pipe diameter are fixed, resulting in a certain drainage capacity. Excessive rainwater will cause floating objects on the roof of the house to gather near the drainage device along with the rainwater. The excess rainwater itself, plus the floating objects, cover the opening of the drainage device, causing the drainage device to be easily blocked. Summary of the Invention

DETAILED DESCRIPTION
[0016] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.
[0017] Please refer to Figures 1 to 4 A roof anti-blocking drainage device, which includes an upper drainage pipe 1, a structural drainage pipe 2, a lower drainage pipe 3 and an auxiliary drainage pipe 4 from top to bottom; the structural drainage pipe 2 is detachably arranged between the upper drainage pipe 1 and the lower drainage pipe 3 respectively; the auxiliary drainage pipe 4 is detachably arranged between the upper drainage pipe 1 and the lower drainage pipe 3 respectively; the structural drainage pipe 2 is a convex structure; a spiral plate 21 and a baffle 22 are respectively provided at both ends of the structural drainage pipe 2.
[0018] Preferably, an extrusion block 11 is further provided above the upper drain pipe 1; the extrusion block 11 is telescopically arranged in the upper drain pipe 1; the middle portion of the extrusion block 11 is hollowed out; and a handle 12 is further provided above the extrusion block 11.
[0019] Preferably, a first structural drainage member 23 is provided on the upper end of the interior of the structural drainage pipe 2; cross fixing plates 24 are provided on the front and rear sides of the first structural drainage member 23; a fixed shaft 25 is also provided between the cross fixing plates 24 on both sides; the spiral plate 21 is staggeredly installed on the fixed shaft 25.
[0020] Preferably, a second structural drainage member 26 is further provided on the lower end inside the structural drainage pipe 2; circular fixing plates 27 are provided on the front and rear sides of the second structural drainage member 26; and the baffle 22 is spaced between the circular fixing plates 27 on both sides.
[0021] Preferably, the baffle 22 is further provided with a guide hole 221 ; the size of the guide hole 221 gradually decreases along the water flow direction of the pipeline.
[0022] Preferably, a filter screen 41 is further provided at the connection between the auxiliary drain pipe 4 and the upper drain pipe 1 and the lower drain pipe 3 .
[0023] Specific implementation:
[0024] Before use, the squeezing block 11 is pulled up by the handle 12 to protrude from the upper drain pipe 1. Since the middle part of the squeezing block 11 is hollowed out, the accumulated water on the roof and smaller debris will flow into the upper drain pipe 1, but at the same time, it can prevent larger debris from falling into the upper drain pipe 1 to avoid serious blockage. After the accumulated water and smaller debris enter the upper drain pipe 1, a small part of the accumulated water will be directly discharged into the lower drain pipe 3 through the auxiliary drain pipe 4. Since the connection between the auxiliary drain pipe 4 and the upper drain pipe 1 and the lower drain pipe 3 is provided with a filter 41, it can effectively prevent excess debris from being discharged into the lower drain pipe 3 and causing blockage of the lower drain pipe 3. The rest of the debris will be discharged into the lower drain pipe 3. The remaining accumulated water continues to be filtered through the structural drainage pipe 2. Since the structural drainage pipe 2 is provided with a first structural drainage member 23 and a second structural drainage member 26, both of which are respectively provided with a spiral plate 21 and a baffle 22. The spiral plate 21 is arranged in the first structural drainage member 23 to help guide the water flow and reduce the impact force of the water flow, thereby reducing the risk of blockage; at the same time, the first structural drainage member 23 is located at the upper end of the structural drainage pipe 2, and is equipped with a cross fixing plate 24 and a fixed shaft 25 to ensure the stability of the spiral plate 21; and the guide hole 221 is arranged on the baffle 22, and the size of the guide hole 221 gradually decreases along the direction of water flow, which helps to smoothly transition the water flow and avoid blockage caused by instantaneous impact.
[0025] The present invention has been described with reference to the above embodiments. However, these embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
