A support device for building water supply and drainage pipes

Abstract

This invention discloses a support device for building water supply and drainage pipes, relating to the field of building engineering technology. It includes a base body, with support components fixedly installed on both sides of the upper surface of the base body. The top of each support component is connected to a clamp holding an external pipe. A shock-absorbing component is located at the center of the upper surface of the base body, including an airbag fixedly installed at the center of the base body. This invention, through the design of the connection component, allows water to flow into the pipe when the valve is opened. The water pressure in the pipe forces the piston inside the piston cylinder to move towards the bottom of the piston cylinder, thereby forcing nitrogen gas inside the piston cylinder through a second connecting pipe and a connecting hose into the airbag ring. After the airbag ring inflates, it completely engages with the annular grooves on the inner sides of the first and second fixing rings, tightly abutting against the inner wall of the annular grooves, achieving further sealing and improving the device's sealing performance. This effectively avoids economic losses caused by water leakage at pipe connections.

Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a support device for building water supply and drainage pipes. Background Technology

[0002] Drainage pipelines refer to the systems of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. They include main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are built on streets or anywhere else, any pipe that serves a drainage function should be counted as a drainage pipeline. Currently, water supply and drainage pipeline engineering is a pipeline system engineering project that transports and distributes industrial water supply and domestic drinking water, and collects, transports, and discharges industrial wastewater, domestic sewage, and rainwater. It is an integral part of the building water supply and drainage system and plays an important role in the entire water supply and drainage system.

[0003] When laying pipes for water supply and drainage in building construction, pipe support devices are often needed at the connection points of two pipes to prevent leakage due to gravity or the opening and closing of valves. Regarding this technology, the inventor found that the stability of pipes supported by common pipe support devices is poor, and water leakage is prone to occur at the pipe connection points, resulting in high maintenance costs in the later stages. Therefore, a support device for building water supply and drainage pipes is proposed. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a building water supply and drainage pipe support device to solve the technical problems mentioned in the background.

[0014] As a preferred technical solution of the building water supply and drainage pipeline support device of the present invention, the base body is provided with mounting holes at the four corners, and the base body is fixedly connected to the external contact surface by bolts passing through the mounting holes.

[0015] In summary, the present invention has the following main beneficial effects:

[0016] 1. This invention designs a docking component. When the operator opens the valve and water flows into the pipe, the water pressure in the pipe squeezes the piston in the piston cylinder to move towards the bottom of the piston cylinder. This forces the nitrogen gas in the piston cylinder through the second connecting pipe and the connecting hose into the airbag ring. After the airbag ring is inflated, it completely engages with the annular grooves opened on the inner sides of the first and second fixed rings and tightly abuts against the inner wall of the annular grooves, completing a further seal. This improves the sealing performance of the device and effectively avoids some economic losses caused by water leakage at the pipe connection.

[0017] 2. This invention designs a filter assembly. When water flows through the pipe, the water pressure in the pipe squeezes the piston in the piston cylinder to move towards the bottom of the piston cylinder, which in turn moves the irregularly shaped connecting rod. This causes the rack to slide on the fixed guide rail, which in turn causes the gear meshing with the rack to start rotating. This causes the scraper fixed to the rack to start rotating, which in turn scrapes the inner wall of the conical filter screen. By setting up the conical filter screen to filter the water, and by setting up the scraper to scrape the inner side of the conical filter screen, the invention prevents impurities in the water from adhering to the surface of the conical filter screen and clogging it, thus affecting the flow of water.

[0018] 3. The present invention designs a shock-absorbing component. When the airbag is installed, it is squeezed by the docking fixing box and is in a state of equilibrium with the nitrogen in the piston cylinder. When water is introduced into the pipe, the water pressure squeezes the piston to move to the bottom of the piston cylinder. Some of the nitrogen inside the piston cylinder will enter the airbag through the first connecting pipe, which further buffers the vibration generated by the valve that should be closed in the pipeline and extends the service life of the pipeline to a certain extent.

[0019] 4. This invention designs a support component. When the operator rotates the turntable, it drives the bidirectional threaded screw to rotate, thereby causing the two sets of sliders to move relative to each other. This causes the support column and the fixing block to move together, thereby causing the clamping block to clamp and fix the outer wall of the pipe, thus providing pipe support. By setting a buffer rubber pad inside the fixing block, the clamping impact is reduced, preventing the water pipe from cracking. At the same time, when water flows through the pipe, the buffer rubber pad can reduce the vibration impact generated. A soft rubber interlayer is installed on the clamping block, which can cover the surface of the water pipe and has elasticity. When the water pipe expands due to heat, it can better protect the water pipe and prevent it from breaking. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of the present invention will now be described.

[0038] A support device for building water supply and drainage pipes, such as Figure 1-10As shown, the system includes a base body 100, with support components 200 fixedly installed on both sides of the upper surface of the base body 100. The top of each support component 200 has a clamp holding an outer connecting pipe 600. A shock-absorbing component 300 is located at the center of the upper surface of the base body 100. The shock-absorbing component 300 includes an airbag 320 fixedly installed at the center of the base body 100. A docking component 400 is installed on top of the airbag 320. The docking component 400 includes a docking fixing box 410 fixedly installed on top of the airbag 320. A filter component 50 is located inside the docking fixing box 410. 0; A connecting pipe 430 is fixedly connected to both sides of the docking fixing box 410. A first flange 440 is fixedly sleeved at the end of the connecting pipe 430 away from the docking fixing box 410. A second flange 450 is fixedly sleeved at one end of the outer connecting pipe 600. A sealing groove 460 is opened inside one side of the first flange 440. A sealing ring 470 is fixedly installed on the side of the second flange 450 near the first flange 440. The sealing ring 470 matches the sealing groove 460. A first fixing ring 480 is sleeved on the outside of the first flange 440, and a second fixing ring 490 is sleeved on the outside of the second flange 450. Both the first flange 440 and the second flange 450 have grooves 4930 on their outer walls. Both the first fixing ring 480 and the second fixing ring 490 have annular grooves 4940 on their inner sides. Airbag rings 4950 are snapped into each groove 4930. A connecting hose 4960 is fixedly connected to the inner side of each airbag ring 4950. A piston cylinder 4970 is fixedly installed at one end of the docking fixing box 410. A piston 4971 is fitted inside the piston cylinder 4970. Second connecting pipes 4980 are fixedly connected to both sides of the bottom of the piston cylinder 4970. The other side of the second connecting pipe 4980... The end is equipped with a connector 4990. Two sets of connecting hoses 4960 pass through the first flange 440 and the second flange 450 respectively and extend to the outside to connect with the connector 4990. Mounting blocks 4910 are fixedly connected to both sides of the first fixing ring 480 and the second fixing ring 490. The first fixing ring 480 and the second fixing ring 490 are fixedly connected to the two sets of mounting blocks 4910 by fastening bolts 4920. Mounting holes 110 are opened at the four corners of the base body 100. The base body 100 is fixedly connected to the external contact surface by bolts passing through the mounting holes 110.

[0039] When connecting the two sets of external connecting pipes 600, the workers align the first flange 440 at one end of the connecting pipe 430 with the second flange 450 at one end of the external connecting pipe 600. At this time, the sealing ring 470, which is fixedly installed with the second flange 450, is fully engaged in the sealing groove 460 in the first flange 440, completing the initial seal. Then, the two airbag rings 4950 are engaged in the grooves 4930 opened on the outside of the first flange 440 and the second flange 450. The connecting hose 4960 passes through the first flange 440 and the second flange 450 and connects to the connector 4990 at one end of the second connecting pipe 4980. Finally, the workers put the first fixing ring 480 and the second fixing ring 490 on the outside of the first flange 440 and the second flange 450 respectively, and use the fastening bolts 4920 to completely fix the first fixing ring 480 and the second fixing ring 490. The first fixing ring 480 and the second fixing ring 490 press the first flange 440 and the second flange 450 against each other to complete the connection. After the valve is opened and water flows into the pipe, the water pressure forces the piston 4971 inside the piston cylinder 4970 to move towards the bottom of the piston cylinder 4970. This forces the nitrogen gas inside the piston cylinder 4970 through the second connecting pipe 4980 and the connecting hose 4960 into the airbag ring 4950. After the airbag ring 4950 is inflated, it completely engages with the annular groove 4940 opened on the inner side of the first fixing ring 480 and the second fixing ring 490, and tightly abuts against the inner wall of the annular groove 4940, completing a further seal. This improves the sealing performance of the device and effectively avoids some economic losses caused by water leakage at the pipe connection. When the valve is closed and no water flows in the pipe, the spring 4991 pushes the piston 4971 to reset through its own force, and the nitrogen in the airbag ring 4950 returns to the piston cylinder 4970. The spring 4991 is in the compressed state when it is initially installed. At the same time, a gas valve is provided at the end of the second connecting pipe 4980. When the second connecting pipe 4980 is connected to the connecting hose 4960, the gas valve is opened.

[0040] Please refer to this carefully. Figure 2 and Figure 7 As shown, the docking fixing box 410 has an opening at the corresponding position of the piston cylinder 4970. Nitrogen gas is provided inside the piston cylinder 4970. Several sets of springs 4991 arranged in a circle are fixedly installed between the bottom of the piston cylinder 4970 and the piston 4971. An L-shaped baffle 4992 is fixedly installed inside the docking fixing box 410.

[0041] The L-shaped baffle 4992 installed inside the docking fixing box 410 provides an initial buffering effect on the water flow in the pipe. At the same time, a spring 4991 is installed at the bottom of the inner cavity of the piston cylinder 4970 on one side of the docking fixing box 410. When water is supplied, the water pressure squeezes the piston 4971 and the spring 4991 to compress, further buffering the water flow in the pipe and preventing the water hammer effect in the pipe from damaging the valve and water pump.

[0042] Please refer to this carefully. Figure 1 and 10 As shown, a first connecting tube 310 is fixedly connected to one side of the airbag cushion 320, and the other end of the first connecting tube 310 is fixedly connected to the bottom of the piston cylinder 4970.

[0043] The nitrogen in the airbag 320 is connected to the nitrogen in the piston cylinder 4970. During installation, the airbag 320 is squeezed by the docking fixing box 410 and is in equilibrium with the nitrogen in the piston cylinder 4970. When water flows through the pipe, the water pressure squeezes the piston 4971 to move towards the bottom of the piston cylinder 4970. Some of the nitrogen inside the piston cylinder 4970 will enter the airbag 320 through the first connecting pipe 310, further buffering the vibration generated by the valve that should be closed in the pipeline and extending the service life of the pipeline to a certain extent.

[0044] Please refer to this carefully. Figure 2 , Figure 8 and Figure 9 As shown, the filter assembly 500 includes an irregularly shaped connecting rod 510 fixedly connected to one side of the piston 4971. The other end of the irregularly shaped connecting rod 510 is fixedly connected to a rack 520. The bottom of the rack 520 is provided with a fixed guide rail 530 fixedly installed with the bottom of the inner cavity of the docking fixed box 410. The rack 520 is slidably connected to the fixed guide rail 530. A gear 540 is meshed on the top of the rack 520. A scraper 560 is fixedly connected to the center of one side of the gear 540. A through hole is opened on one side of the L-shaped baffle 4992, and a conical filter screen 570 is fixedly installed at the through hole. The scraper 560 is in contact with the inner wall of the conical filter screen 570.

[0045] When water flows through the pipe, the water pressure forces the piston 4971 inside the piston cylinder 4970 to move towards the bottom of the piston cylinder 4970, simultaneously moving the irregularly shaped connecting rod 510. This causes the rack 520 to slide on the fixed guide rail 530, which in turn causes the gear 540 meshing with the rack 520 to start rotating. This causes the scraper 560 fixed to the rack 520 to start rotating, scraping the inner wall of the conical filter screen 570 to prevent poor-quality water from passing through the pipe and causing blockage over time. The conical filter screen 570 filters the water, and the scraper 560 scrapes the inner side of the conical filter screen 570 to prevent impurities in the water from adhering to the surface of the conical filter screen 570 and blocking it, thus affecting the water flow. The scraper 560 rotates at the times when the valve is opened and closed.

[0046] Please refer to this carefully. Figure 1 , Figure 7 and Figure 8As shown, a sealing cover plate 420 is fixedly installed on the top of the docking fixing box 410. An L-shaped fixing column 550 is connected to the center of the gear 540 away from the scraper 560 via a bearing. The L-shaped fixing column 550 is fixedly connected to the bottom of the sealing cover plate 420. A fixing collar 580 is fixedly sleeved on the outside of the conical filter screen 570. The outside of the fixing collar 580 is fixedly connected to the inner wall of the docking fixing box 410 via a fixing rod.

[0047] The gear 540 is fixed by setting an L-shaped fixing post 550, and the cone filter screen 570 is further fixed by setting a fixing collar 580 to prevent the cone filter screen 570 from falling off under the impact of water flow. At the same time, the cone filter screen 570 is designed in a cone shape to minimize the impact force of water flow on the cone filter screen 570 and prevent the cone filter screen 570 from breaking under the impact of water flow. The sealing cover plate 420 is set to facilitate the maintenance and replacement work of the staff.

[0048] Please refer to this carefully. Figure 1 and Figure 2 As shown, the support assembly 200 includes a fixing plate 210 fixedly installed on both sides of the upper surface of the base body 100. The fixing plate 210 has a sliding groove inside, and one end of the sliding groove is connected to a bidirectional threaded rod 220 through a bearing. A turntable 230 is fixedly installed on one end of the bidirectional threaded rod 220. Slider 240s are threadedly sleeved on both ends of the outer side of the bidirectional threaded rod 220. Support columns 250 are fixedly connected to the top of the two sets of sliders 240. A fixing block 260 is fixedly connected to the top of each set of support columns 250. A fixing column 280 is slidably connected to one side of the fixing block 260. A clamping block 290 is fixedly installed on the other end of the fixing column 280. A buffer rubber pad 270 is fixedly installed on one end of the fixing column 280 inside the fixing block 260. The clamping block 290 is semi-circular, and a soft rubber interlayer 2910 is installed on its side.

[0049] During installation, the operator rotates the turntable 230, which drives the bidirectional threaded screw 220 to rotate, thereby causing the two sets of sliders 240 to move relative to each other. This, in turn, moves the support column 250 and the fixing block 260 together, thereby causing the clamping block 290 to clamp and fix the outer wall of the pipe, thus providing pipe support. By setting a buffer rubber pad 270 inside the fixing block 260, the clamping impact is reduced, preventing the water pipe from cracking. At the same time, when water flows through the pipe, the buffer rubber pad 270 can reduce the vibration impact generated. A soft rubber interlayer 2910 is installed on the clamping block 290, which can cover the surface of the water pipe and has elasticity. When the water pipe expands due to heat, it can better protect the water pipe and prevent it from cracking.

[0050] In use, the first flange 440 at one end of the connecting pipe 430 is joined to the second flange 450 at one end of the outer connecting pipe 600. At this time, the sealing ring 470, which is fixedly installed with the second flange 450, is fully engaged in the sealing groove 460 in the first flange 440, completing the initial seal. Then, the two airbag rings 4950 are engaged in the grooves 4930 opened on the outside of the first flange 440 and the second flange 450. The connecting hose 4960 passes through the first flange 440 and the second flange 450 and is connected to the connector 4990 at one end of the second connecting pipe 4980. Finally, the operator puts the first fixing ring 480 and the second fixing ring 490 on the outside of the first flange 440 and the second flange 450 respectively, and uses the fastening bolts 4920 to completely fix the first fixing ring 480 and the second fixing ring 490. The first fixing ring 480 and the second fixing ring 490 squeeze the first flange 440 and the second flange 450 together to complete the docking. When the operator opens the valve and water flows into the pipe, the water pressure in the pipe squeezes the piston. The piston 4971 inside the piston cylinder 4970 moves towards the bottom of the piston cylinder 4970, thereby forcing the nitrogen gas inside the piston cylinder 4970 through the second connecting pipe 4980 and the connecting hose 4960 into the airbag ring 4950. After the airbag ring 4950 is inflated, it completely engages with the annular groove 4940 opened on the inner side of the first fixing ring 480 and the second fixing ring 490, and tightly abuts against the inner wall of the annular groove 4940, completing a further seal, thereby improving the sealing performance of the device and effectively preventing water leakage at the pipe connection. Some economic losses will occur when the valve is closed and no water flows through the pipeline. The spring 4991 will push the piston 4971 to reset through its own force, and the nitrogen in the airbag ring 4950 will return to the piston cylinder 4970. The spring 4991 is in a compressed state when it is initially installed. At the same time, a gas valve is provided at the end of the second connecting pipe 4980. When the second connecting pipe 4980 is connected to the connecting hose 4960, the gas valve will be opened. The parts of this device not mentioned are the same as or can be implemented using existing technology.
