Abstract
Description
Technical Field
[0001] This utility model relates to the field of building water supply and drainage engineering technology, and more specifically to an energy dissipation device for drainage pipes in high-rise buildings. Background Technology
[0002] Energy dissipation devices for drainage pipes in high-rise buildings are special devices installed in drainage systems to reduce water flow velocity and kinetic energy, thereby protecting the pipe system, reducing noise, and improving drainage safety. Their core function is to consume or convert the energy of high-speed water flow generated by large vertical drops in high-rise buildings by changing the water flow pattern and increasing water flow resistance, thus avoiding damage to the pipe system.
[0003] A search revealed a utility model patent with publication number CN221548088U, which discloses an energy dissipation device for drainage pipes in high-rise buildings. The device includes an energy dissipation pipe with a flow diversion section in the middle. An arc-shaped connecting plate is installed inside the energy dissipation pipe, and a rubber energy dissipation sheet is fixedly installed on the upper end of the arc-shaped connecting plate. A spring sheet is fixedly installed on one side of the arc-shaped connecting plate, and the rubber energy dissipation sheet and the spring sheet cooperate with each other. An inspection port is provided on the front of the energy dissipation pipe, and connecting plates are fixedly installed at both the upper and lower ends of the energy dissipation pipe.
[0004] The energy dissipation scheme of this patent mainly relies on the elastic deformation of the rubber energy dissipation sheet through the arc-shaped connecting plate to dissipate water flow energy. However, in practical applications, the arc-shaped connecting plate will experience elastic decay after long-term use, causing the energy dissipation effect of the rubber energy dissipation sheet on the water flow to gradually decrease. Although the elasticity of the connecting plate can be observed through the inspection port, when the rubber energy dissipation sheet or the arc-shaped connecting plate needs to be replaced, the entire device must be dismantled. This process will cause the drainage system to temporarily stop operating, which will lead to problems such as the inability of the toilet to drain normally and sewage retention, seriously affecting the daily life of residents in the building or the work order of users. In addition, since the components cannot be repaired after the elasticity is weakened and can only be replaced as a whole, it will also cause unnecessary waste of materials. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an energy dissipation device for drainage pipes in high-rise buildings to solve the problems existing in the background art.
[0006] The utility model provides the following technical solution: an energy dissipation device for drainage pipes in high-rise buildings, including an energy dissipation pipe, a flow guide shroud fixedly connected to the side of the energy dissipation pipe, an energy dissipation plate fixedly connected to the inner wall of the energy dissipation pipe, a pressure boosting component installed on the outer surface of the energy dissipation pipe, a stop rod fixedly connected to the output end of the pressure boosting component, the outer surface of the stop rod being laterally sealed and slidably connected to the inside of the energy dissipation pipe, the end face of the stop rod away from the pressure boosting component being arc-shaped, and the arc-shaped end face of the stop rod abutting against the surface of the energy dissipation plate, and the input end of the pressure boosting component being away from the stop rod.
[0007] Furthermore, the pressurization assembly includes a fixed cylinder fixedly connected to the outer surface of the energy dissipation pipe. A sealing plate and a sliding column are slidably connected inside the fixed cylinder. A limiting plate is fixedly connected inside the fixed cylinder between the sliding column and the sealing plate. The end face of the abutment is fixedly connected to the center of the surface of the sealing plate. A bearing is fixedly installed at the end of the fixed cylinder away from the sealing plate. A bolt is fixedly connected to the inner ring of the bearing. A threaded hole is opened at the center of the sliding column. The outer surface of the bolt is threaded into the threaded hole. A limiting rod is fixedly connected to the inner wall of the fixed cylinder. A limiting groove matching the limiting rod is opened inside the sliding column. The outer surface of the limiting rod is inserted into the limiting groove. An exhaust pipe communicating with the inside of the fixed cylinder is fixedly connected inside the fixed cylinder. A pressure gauge is fixedly installed on the outer surface of the fixed cylinder. The input end of the pressure gauge is fixedly connected to the inside of the limiting plate and communicates with the inside of the fixed cylinder.
[0008] Furthermore, sealing rings are fixedly installed on the outer surfaces of both the sliding column and the sealing plate, and the interior of the fixed cylinder is under high pressure between the sliding column and the sealing plate.
[0009] Furthermore, the output end of the exhaust pipe extends to the outer surface of the fixed cylinder, and the limiting plate is annular.
[0010] Furthermore, the energy dissipation plate is made of stainless steel and is arc-shaped. The interior of the energy dissipation pipe is connected to the interior of the flow guide shroud. The outer surface of the energy dissipation plate is movably connected to the interior of the flow guide shroud. Under normal conditions, the elasticity of the energy dissipation plate causes the end of the energy dissipation plate to move towards the booster assembly.
[0011] Furthermore, the end of the bolt away from the limiting plate extends to the outer surface of the fixing cylinder, and the end of the fixing cylinder away from the sealing plate is in a non-sealed state.
[0012] Furthermore, a sealing ring is fixedly connected inside the energy dissipation pipe, and the outer surface of the abutment is slidably connected to the inner wall of the sealing ring. Flanges are provided at both ends of the energy dissipation pipe.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. This utility model, through the arc-shaped structure of the energy dissipation plate and its cooperation with the flow guide, can effectively change the direction of water flow and increase resistance, converting the kinetic energy of high-speed water flow into the elastic deformation potential energy of the energy dissipation plate, realizing the gradual consumption of water flow energy, reducing the impact of water flow on the pipeline. The pressurization component, through the linkage design of the high-pressure environment and the abutment rod, can dynamically adjust the abutment pressure according to the elastic state of the energy dissipation plate. When the elasticity of the energy dissipation plate decreases after long-term use, the pressure inside the fixed cylinder can be increased simply by adjusting the position of the sliding column with bolts, pushing the abutment rod to strengthen the support force on the energy dissipation plate. There is no need to disassemble the entire device, which significantly improves the stability of the energy dissipation effect and the convenience of maintenance.
[0015] 2. This utility model uses a pressure gauge to monitor pressure changes inside the fixed cylinder in real time. Maintenance personnel can intuitively judge the elastic performance of the energy dissipation plate through the pressure value, and the condition assessment can be completed without disassembling the pipeline, which greatly reduces maintenance and time costs. The flange design at both ends of the energy dissipation pipeline ensures quick connection with existing drainage pipelines. The sealing ring and the sealing sliding structure of the abutment prevent water leakage. The overall device has a compact structure and is easy to install. It is suitable for the standardized renovation of drainage systems in high-rise buildings, and the adjustment process does not affect the normal drainage of the pipeline, ensuring that residents' lives and work are not disturbed.

Detailed Implementation
[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.
[0022] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.
[0023] A high-rise building drainage pipe energy dissipation device includes an energy dissipation pipe 1, a flow guide hood 2 fixedly connected to the side of the energy dissipation pipe 1, an energy dissipation plate 3 fixedly connected to the inner wall of the energy dissipation pipe 1, a pressure boosting component 4 installed on the outer surface of the energy dissipation pipe 1, a stop rod 5 fixedly connected to the output end of the pressure boosting component 4, the outer surface of the stop rod 5 being laterally sealed and slidably connected to the inside of the energy dissipation pipe 1, the end face of the stop rod 5 away from the pressure boosting component 4 being arc-shaped, and the arc-shaped end face of the stop rod 5 abutting against the surface of the energy dissipation plate 3, and the input end of the pressure boosting component 4 being away from the stop rod 5.
[0024] In this embodiment, the arc-shaped structure of the energy dissipation plate 3 and the internal space of the flow guide shroud 2 form a flow channel. When water flows through, the arc-shaped surface forces the water flow to change direction and impact the energy dissipation plate 3. By increasing the water flow path resistance and elastic deformation energy dissipation (the energy dissipation plate 3 stores potential energy under pressure bending), the kinetic energy of the water flow is converted into potential energy, reducing the water flow speed and the impact force on the pipe. The arc-shaped end face of the abutment rod 5 (which is in contact with the energy dissipation plate 3) provides reverse support force to the energy dissipation plate 3 through the thrust of the pressurization component 4, enhancing its impact resistance. At the same time, by dynamically adjusting the support force, the stability of the long-term energy dissipation effect is maintained.
[0025] Specifically, the pressurization assembly 4 includes a fixed cylinder 41 fixedly connected to the outer surface of the energy dissipation pipe 1. A sealing plate 42 and a sliding column 44 are slidably connected inside the fixed cylinder 41. A limit plate 43 is fixedly connected inside the fixed cylinder 41 between the sliding column 44 and the sealing plate 42. The end face of the abutment 5 is fixedly connected to the center of the surface of the sealing plate 42. A bearing 45 is fixedly installed at the end of the fixed cylinder 41 away from the sealing plate 42. A bolt 46 is fixedly connected to the inner ring of the bearing 45. A threaded hole 47 is provided at the center of the sliding column 44. The outer surface of the bolt 46 is threaded into the inside of the threaded hole 47. A limit bar 48 is fixedly connected to the inner wall of the fixed cylinder 41. A limit groove 49 matching the limit bar 48 is opened inside the sliding column 44. The outer surface of the limit bar 48 is inserted into the inside of the limit groove 49. An exhaust pipe 411 communicating with the inside of the fixed cylinder 41 is fixedly connected inside the fixed cylinder 41. A pressure gauge 410 is fixedly installed on the outer surface of the fixed cylinder 41. The input end of the pressure gauge 410 is fixedly connected to the inside of the limit plate 43 and communicates with the inside of the fixed cylinder 41.
[0026] In this embodiment, the high-pressure environment inside the fixed cylinder 41 (between the sliding column 44 and the sealing plate 42) is driven by the rotation of the bolt 46 to move the sliding column 44 (the limit bar 48 and the limit groove 49 cooperate to limit the rotation of the sliding column 44 to ensure linear movement). This changes the internal air / hydraulic pressure, pushing the sealing plate 42 and the abutment 5 to adjust the support force on the energy dissipation plate 3. When the elasticity of the energy dissipation plate 3 decreases, the bolt 46 is rotated clockwise to bring the sliding column 44 closer to the sealing plate 42, increasing the internal pressure. The thrust of the abutment 5 increases, compensating for the elastic loss of the energy dissipation plate 3. Maintenance can be performed without disassembling the device. The pressure gauge 410 displays the pressure inside the fixed cylinder 41 in real time. A decrease in pressure value can directly reflect the weakening of the elasticity of the energy dissipation plate 3 (due to the reduced thrust required for the deformation of the energy dissipation plate 3). Maintenance personnel can determine the maintenance needs through the pressure data, avoiding blind disassembly of the pipeline and reducing maintenance costs. The exhaust pipe 411 is used to release excess gas on the right side of the fixed cylinder 41 to maintain stable internal pressure and prevent overpressure damage to the components.
[0027] Specifically, sealing rings are fixedly installed on the outer surfaces of both the sliding column 44 and the sealing plate 42, and the interior of the fixed cylinder 41 is under high pressure between the sliding column 44 and the sealing plate 42.
[0028] In this embodiment, the sealing ring ensures the airtightness of the high-pressure environment inside the fixed cylinder 41, prevents gas leakage, and guarantees the stability of the thrust of the push rod 5 and the reliability of the pressurization component 4.
[0029] Specifically, the output end of the exhaust pipe 411 extends to the outer surface of the fixed cylinder 41, and the limiting plate 43 is annular.
[0030] In this embodiment, the external design of the exhaust pipe 411 facilitates gas discharge and maintenance operations. The annular limiting plate 43 divides the interior of the fixed cylinder 41 into a pressure chamber (between the sliding column 44 and the sealing plate 42) and a non-pressure chamber, providing an independent pressure monitoring channel for the pressure gauge 410, while supporting the sliding trajectory of the sliding column 44 and the sealing plate 42, thus enhancing structural stability.
[0031] Specifically, the energy dissipation plate 3 is made of stainless steel and is arc-shaped. The interior of the energy dissipation pipe 1 is connected to the interior of the flow guide shroud 2. The outer surface of the energy dissipation plate 3 is movably connected to the interior of the flow guide shroud 2. Under normal conditions, the elasticity of the energy dissipation plate 3 causes the end of the energy dissipation plate 3 to move towards the booster assembly 4.
[0032] In this implementation scheme, stainless steel is corrosion resistant and has high strength, which extends the service life of the energy dissipation plate 3. The arc structure optimizes the flow guiding effect and increases the water flow impact area. Under normal conditions, the elastic reset (the end is close to the pressurization component 4) keeps the energy dissipation plate 3 at its initial tension, ensuring effective deformation and energy dissipation when the water flow impacts. At the same time, it works with the thrust of the abutment rod 5 to achieve dynamic balance.
[0033] Specifically, the end of the bolt 46 away from the limiting plate 43 extends to the outer surface of the fixing cylinder 41, and the end of the fixing cylinder 41 away from the sealing plate 42 is in a non-sealed state.
[0034] In this embodiment, the exposed bolt 46 allows for direct adjustment with tools (such as a wrench), making operation convenient. The non-sealed end of the fixed cylinder 41 (the side of bolt 46) allows air circulation, preventing the formation of a vacuum inside and ensuring smooth movement of the sliding column 44.
[0035] Specifically, the energy dissipation pipe 1 is internally fixedly connected to a sealing ring 6, and the outer surface of the abutment 5 is slidably connected to the inner wall of the sealing ring 6. Flanges are provided at both ends of the energy dissipation pipe 1.
[0036] In this implementation scheme, the sealing ring 6 and the abutment 5 are sealed and slidingly fitted to prevent water from leaking through the gap between the abutment 5 and the pipe in the energy dissipation pipe 1. The flange enables the energy dissipation device to be quickly connected to the existing drainage pipe. It is easy to install and has strong sealing performance. It is suitable for the standardized renovation of drainage systems in high-rise buildings without the need for large-scale modifications to the original pipes.
[0037] The working principle and usage process of this utility model are as follows: During fixing, the flanges at both ends of the energy dissipation pipe 1 are directly sealed to the drainage pipe. After the sewage from the high-rise building enters the drainage pipe, it enters the energy dissipation pipe 1. The energy dissipation plate 3 guides the water flow, effectively dissipating the impact force. Under pressure, the energy dissipation plate 3 bends towards the pressure boosting component 4. The energy dissipation plate 3 then drives the abutment 5 to slide towards the pressure boosting component 4. The abutment 5 drives the sealing plate 42 to slide inside the fixed cylinder 41. Because the inside of the fixed cylinder 41 is under high pressure, combined with the elasticity of the energy dissipation plate 3, it can easily... To reset the energy dissipation plate 3, when the elasticity of the energy dissipation plate 3 weakens, the bolt 46 is rotated clockwise by a wrench. Through the engagement of the bolt 46 with the threaded hole 47, the sliding column 44 is moved closer to the sealing plate 42. At this time, the pressure between the sliding column 44 and the sealing plate 42 increases, and the pressure of the abutment 5 on the energy dissipation plate 3 increases, so that the energy dissipation plate 3 can work normally. In daily maintenance, the maintenance personnel can directly observe the pressure of the pressure gauge 410 to quickly detect the elasticity of the energy dissipation plate 3. When adjusting, it can also be adjusted directly without disassembly and will not affect the normal operation of the drainage pipe.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
