[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] Example: Figure 1-4 As shown, this utility model provides a technical solution, a prefabricated building exterior wall drainage structure, including a drainage pipe body 1, and a splicing flared mouth 2 is provided at the middle of the top of the drainage pipe body 1.

[0034] A splicing buffer installation mechanism 3 is provided on the outside of the main body 1 of the drainage pipe;

[0035] The splicing buffer installation mechanism 3 includes a connecting arc plate 301, a protective retaining ring 302, a connecting round frame 303, a supporting bend plate 304, a supporting rubber rod 305, a sealing corner block 306, and an installation crossbeam 307.

[0036] A connecting arc-shaped plate 301 is evenly and equidistantly fitted onto the outer side of the main body 1 of the drain pipe. Protective retaining rings 302 are embedded in the inner sides of both the top and bottom surfaces of the connecting arc-shaped plate 301. A connecting circular frame 303 is fixedly connected to the middle of one end of each protective retaining ring 302. A supporting bend plate 304 is movably connected to the outer side of the connecting circular frame 303 at the bottom position corresponding to the connecting arc-shaped plate 301. Supporting rubber rods 305 are embedded in the two corners of the bottom surface of the connecting arc-shaped plate 301. A sealing corner block 306 is snapped into the top of the inner side of the supporting bend plate 304 at the top position corresponding to the connecting circular frame 303. A mounting crossbeam 307 is fixedly connected to the middle of the back of the supporting bend plate 304. The inner side of the protective retaining ring 302 slides tightly against the outer side of the main body 1 of the drain pipe. The bottom end of the supporting rubber rod 305 is fixedly connected to the end of the supporting bend plate 304. A mounting crossbeam 307 is opened at the middle of both ends of the mounting crossbeam 307. The support bend plate 304 and its components are installed on the building exterior wall using expansion bolts and mounting bracket 307. The main body of the drainage pipe 1 is connected to one side of the mounting bracket 307 via the connecting arc plate 301 and the connecting round bracket 303. When the main body of the drainage pipe 1 is impacted by the internal water flow, the extension and retraction of the support rubber rod 305 buffers and dissipates the kinetic energy transmitted from the main body of the drainage pipe 1 to the connecting arc plate 301. The top of the support bend plate 304 is sealed by the sealing corner block 306 to prevent external dirt from accumulating in the top cavity of the connecting round bracket 303. Furthermore, the elastic movable connection structure between the connecting arc plate 301 and the support bend plate 304 effectively prevents the drainage pipe from shaking during use, thus effectively improving the stability and service life of the drainage pipe installation.

[0037] A dynamic counterweight sealing mechanism 4 is installed at the bottom outer side of the main body 1 of the drain pipe;

[0038] The dynamic counterweight sealing mechanism 4 includes a sealing ring 401, a splicing conical ring 402, an injection conical groove 403, a sol tank 404, and a counterweight extrusion ring 405.

[0039] A sealing ring 401 is tightly fitted onto the bottom outer side of the main body 1 of the drain pipe. A splicing conical ring 402 is bonded to the bottom end of the sealing ring 401. An injection conical groove 403 is formed on the inner side of the top of the sealing ring 401. A molten adhesive groove 404 is evenly spaced along the circumference on the top inner side of the sealing ring 401. A counterweight compression ring 405 is fitted onto the outer side of the main body 1 at the position corresponding to the top of the injection conical groove 403. During the splicing process, the splicing conical ring 402 engages with the corresponding splicing flared end 2. The bottom conical surface of the counterweight compression ring 405 engages with the injection conical groove 403. The splicing conical ring 402 at the bottom of the sealing ring 401 engages with the top of the splicing flared end 2. The gap between the main body 1 of the previous drain pipe and the outer side is filled and sealed. Then, the sealant is filled into the molten adhesive tank 404 through the injection cone groove 403. The sealant inside the molten adhesive tank 404 fixes the sealing ring 401 and the splicing cone ring 402, thereby effectively improving the sealing performance of the connection between the drain pipes. The sealing ring 401 is continuously squeezed by the counterweight compression ring 405, causing the sealing ring 401 and the splicing cone ring 402 to expand outward under the compression of the counterweight compression ring 405, further improving the sealing performance of the connection between the main body 1 of the drain pipe and the splicing flared mouth 2, and optimizing the stability of the drainage structure system.

[0040] An auxiliary marking display mechanism 5 is provided on the outside of the main body 1 of the drain pipe;

[0041] The auxiliary marking display mechanism 5 includes an elongated groove 501, a fluorescent strip 502, and a marking groove 503;

[0042] Equally spaced elongated grooves 501 are provided on the outer side of the main body 1 of the drain pipe. A fluorescent strip 502 is adhered inside the elongated groove 501. Marking grooves 503 are evenly provided on the outer side of the fluorescent strip 502. The outer side of the fluorescent strip 502 is flush with the outer side of the main body 1 of the drain pipe. The marking grooves 503 are coated with opaque pigment. By installing the elongated grooves 501, the fluorescent strip 502 and the marking grooves 503 can be installed on the outer side of the main body 1 of the drain pipe. The position of the main body 1 of the drain pipe is indicated by the fluorescent strip 502 that glows at night, and the overall shape of the main body 1 of the drain pipe can be predicted by the distribution and position changes of the marking grooves 503. Damage to the main body 1 of the drain pipe can be detected in time, which further improves the safety and stability of the drain pipe.

[0043] The working principle and usage process of this utility model: In the actual application process, when installing the main body 1 of the drainage pipe in the drainage structure, the main body 1 of the upper drainage pipe needs to be inserted into the splicing horn mouth 2 of the lower layer to complete the assembly of the drainage pipe. The support bend plate 304 and its components are installed on the building exterior wall by means of expansion bolts and installation crossbeam 307. The main body 1 of the drainage pipe is connected to one side of the installation crossbeam 307 by means of connecting arc plate 301 and connecting round frame 303.

[0044] When the main body of the drainage pipe 1 is impacted by the internal water flow, the extension and retraction of the supporting rubber rod 305 buffers and dissipates the kinetic energy transmitted from the main body of the drainage pipe 1 to the connecting arc plate 301. The sealing corner block 306 seals the top of the supporting bend plate 304 to prevent external dirt from accumulating in the top cavity of the connecting round frame 303. Furthermore, the elastic movable connection structure between the connecting arc plate 301 and the supporting bend plate 304 effectively prevents the drainage pipe from shaking during use, thus effectively improving the stability and service life of the drainage pipe installation.

[0045] When it is necessary to seal the top interface of the spliced ​​flared mouth 2, the gap between the top of the spliced ​​flared mouth 2 and the outer side of the previous drain pipe body 1 is filled and sealed by the splicing conical ring 402 at the bottom of the sealing ring 401. Then, the sealant is filled into the molten glue tank 404 through the glue injection conical groove 403. The sealant inside the molten glue tank 404 fixes the sealing ring 401 and the splicing conical ring 402, thereby effectively improving the sealing performance of the connection between the drain pipes. The sealing ring 401 is continuously squeezed by the counterweight compression ring 405, causing the sealing ring 401 and the splicing conical ring 402 to expand outward under the compression of the counterweight compression ring 405, further improving the sealing performance of the connection between the corresponding drain pipe body 1 and the spliced ​​flared mouth 2, and optimizing the stability of the drainage structure system.

[0046] When it is necessary to inspect the main body 1 of the drainage pipe at night, the fluorescent strip 502 and the marking groove 503 can be installed on the outside of the main body 1 of the drainage pipe by installing the elongated groove 501. The fluorescent strip 502 illuminates the position of the main body 1 at night, and the overall shape of the main body 1 can be predicted by the distribution and position changes of the marking groove 503, so as to detect damage to the main body 1 of the drainage pipe in time, thereby improving the safety and stability of the drainage pipe.
