Description

[0001] This application was filed on November 17, 2022, with application number 2022114404363.

[0002] The divisional application is entitled "An anti-vibration structure for hot water heating pipes". Technical Field

[0003] This invention relates to the field of heating pipeline construction technology, and in particular to a buried structure for a horizontal and vertical bidirectional buffer hot water heating pipeline. Background Technology

[0004] Heating pipelines, also known as heating networks, refer to the pipelines that transmit heat from heating centers to buildings. Hot water heating pipelines, as circulation heating pipelines for high-temperature hot water, can transport hot water from heating centers to buildings. When heating pipelines are suspended in the air, vibrations from external mechanical equipment or buildings, as well as the impact of high-pressure fluids inside the pipelines, can cause vibration and impact. In order to ensure the safe operation of heating pipelines, vibration-resistant treatment is required.

[0005] Chinese Patent Publication No. CN216520267U discloses "Anti-vibration Pipeline for Thermal Power Plants," comprising a pipe body, with vibration isolation pipes connected to both ends of the pipe body along the axial direction. A connecting flange is provided at the end of the vibration isolation pipe furthest from the pipe body, and a vibration isolation pad is provided on the connecting surface of the connecting flange. Both the vibration isolation pipe and the vibration isolation pad are made of damping material. This design can reduce vibration transmitted from the preceding pipe and weaken vibration transmission through the vibration isolation pad and vibration isolation flange.

[0006] Existing vibration-resistant structures typically employ transverse and longitudinal vibration-resistant structures to treat heating pipelines. However, because the transverse and longitudinal vibration-resistant structures are independent of each other, the impact force cannot be diffused and transmitted, thus failing to provide efficient buffering and pressure relief of the impact force, which is detrimental to the vibration protection effect of the heating pipelines. Summary of the Invention

[0007] The purpose of this invention is to provide a bidirectional buffer structure for buried hot water heating pipelines that uses a combination of vertical and horizontal anti-vibration structures to diffuse and transmit impact forces and relieve pressure, thereby improving the vibration resistance of heating pipelines.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a buried structure for a horizontal and vertical bidirectional buffer hot water heating pipeline, comprising a U-shaped upper support and a U-shaped lower support, wherein the upper and lower supports are connected by a U-shaped interlocking plate, and both the upper and lower supports are provided with interlocking grooves near the connection point, the interlocking plate cooperating with the interlocking grooves; the inner wall of the upper support is provided with a V-shaped upper clamping plate with an opening facing downwards, and a clamping component that contacts the heating pipeline is movably connected to the lower support; a vertical buffering component that moves vertically along the vertical direction of the heating pipeline is provided at the top of the upper support; a horizontal buffering component is provided at the top of the upper support and outside the vertical buffering component; the vertical buffering component includes a hanger rod provided at the top of the upper support, and a damping spring shock absorber is provided at the top of the hanger rod, and the damping spring shock absorber... The top of the nylon spring shock absorber is equipped with a hanger, which is fixed to the top of the building by expansion bolts. The lateral buffer assembly includes a housing set on the top of the upper support. The inner wall of the housing is embedded with a buffer seat connected to the hanger rod. The outer side of the buffer seat is wrapped with an air storage pipe, and the outer side of the air storage pipe is wrapped with a spacer ring. An oil storage pipe is set between the spacer ring and the inner wall of the housing. When the hanger rod is subjected to external force and shakes, or when the pressure of the hot water flow in the heating pipe is too high and impacts the heating pipe, the impact force on the hanger rod or the heating pipe will act on the buffer seat, causing the buffer seat to move circumferentially within the housing and squeeze the air storage pipe to provide lateral primary buffering of the impact force. After the air storage pipe is excessively deformed by pressure, it will drive the spacer ring to move outward and squeeze the oil storage pipe to be slowly squeezed and deformed, thus providing lateral secondary buffering of the buffer seat.

[0009] Optionally, the clamping assembly includes a clamping rod spirally disposed on the lower support, the end of the clamping rod being provided with a bearing, and the bearing being provided with a V-shaped lower clamping plate with an upward opening.

[0010] Optionally, the inner wall of the vertical end of the upper bracket is provided with a limiting groove that matches the lower clamping plate, and the upper clamping plate is provided with an extension groove that matches the lower clamping plate. The extension groove and the limiting groove are interconnected. When the diameter of the heating pipe is small, the lower clamping plate will enter the extension groove along the limiting groove, thereby reducing the clamping space between the upper and lower clamping plates.

[0011] Optionally, rubber pads are provided on the upper clamping plate and on both sides of the extension groove.

[0012] Optionally, the bottom of the lower support is provided with a hollow and arc-shaped protective cover, the inner wall of the opening end of the protective cover is provided with a screw groove, and the bottom edge of the lower support is provided with a thread, so that the protective cover can be spirally connected to the bottom of the lower support.

[0013] In the above technical solution, the buried structure of a horizontal and vertical bidirectional buffer hot water heating pipeline provided by the present invention has the following beneficial effects:

[0014] This vibration-resistant structure, through its vertical buffer components, allows the heating pipe to move slowly and slightly in the vertical direction when subjected to vertical impact vibrations, thus providing vertical vibration protection for the heating pipe. At the same time, combined with the secondary buffering effect of the horizontal buffer components, it can effectively buffer and reduce the lateral impact force on the heating pipe, achieving a combined lateral and vertical vibration-resistant effect for the heating pipe.

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figures 1-3 As shown, a buried structure for a horizontal and vertical bidirectional buffer hot water heating pipeline includes a U-shaped upper support 4 and a U-shaped lower support 6.

[0024] The upper bracket 4 and the lower bracket 6 are connected by a U-shaped interlocking plate 5. Both the upper bracket 4 and the lower bracket 6 are provided with interlocking grooves near the connection point. When the upper bracket 4 and the lower bracket 6 are aligned and in contact, the two ends of the U-shaped interlocking plate 5 can be inserted into the two interlocking grooves to connect and reinforce the upper bracket 4 and the lower bracket 6, so that they form an integral structure.

[0025] The inner wall of the upper support 4 is provided with a V-shaped upper clamping plate 9 with the opening facing downward. The lower support 6 is movably connected with a clamping component 8 that contacts the heating pipe. The clamping component 8 is located below the heating pipe and drives the heating pipe to move upward and contact the upper clamping plate 9 to clamp it, thus clamping and reinforcing the heating pipe.

[0026] The top of the upper support 4 is equipped with three vertical buffer components that move vertically along the direction of the heating pipe. The vertical buffer component in the middle position is a vertical structure, while the vertical buffer components on both sides are inclined structures. This can form a multi-point support and buffer protection function. When the heating pipe is subjected to vertical impact vibration, the vibration-resistant structure and the heating pipe move slowly and slightly in the vertical direction, thereby providing vertical vibration protection for the heating pipe and dispersing excessive impact force. This helps to prevent the heating pipe from vibrating excessively and causing cracks at the pipe connection.

[0027] A horizontal buffer component 10 is provided on the top of the upper support 4 and outside the vertical buffer component. When the hanger 3 is shaken by external force or the hot water flow pressure in the heating pipe is too high and impacts the heating pipe, the upper support 4 and the hanger 3 can move laterally in the horizontal direction, thereby achieving an efficient buffering and shock absorption effect on the lateral impact force on the heating pipe, and realizing the combined lateral and vertical anti-vibration effect of the heating pipe.

[0028] The clamping assembly 8 includes a clamping rod 81 spirally mounted on the lower support 6. The end of the clamping rod 81 is provided with a bearing 82, and the bearing 82 is provided with a V-shaped lower clamping plate 83 with its opening facing upward. Rotating the clamping rod 81 causes it to rotate on the lower support 6, and under the action of the bearing 82, it drives the lower clamping plate 83 to move upward and contact the bottom of the heating pipe. At the same time, under the combined action of the upper clamping plate 9, it can clamp and reinforce the heating pipe, ensuring that the heating pipe can be stably suspended and fixed.

[0029] The upper support 4 has a limiting groove 41 on the inner wall of its vertical end that is adapted to the lower clamping plate 83. The upper clamping plate 9 has an extension groove 91 that is adapted to the lower clamping plate 83. The extension groove 91 and the limiting groove 41 are interconnected. When the clamping rod 81 is rotated to drive the lower clamping plate 83 to move, the lower clamping plate 83 will move linearly in the limiting groove 41 to ensure the stability of the movement of the lower clamping plate 83. When the diameter of the heating pipe is small, the lower clamping plate 83 will enter the extension groove 91 along the limiting groove 41, which can reduce the clamping space between the upper clamping plate 9 and the lower clamping plate 83, thereby meeting the clamping and fixing requirements of heating pipes of different sizes.

[0030] Rubber gaskets 92 are provided on the upper clamping plate 9 and on both sides of the extension groove 91, which can provide elastic protection between the heating pipe and the upper clamping plate 9.

[0031] The vertical buffer assembly includes a hanger 3 mounted on the top of the upper support 4. A damping spring shock absorber 2 is mounted on the top of the hanger 3, and a hanger 1 is mounted on the top of the damping spring shock absorber 2. The hanger 1 is fixed to the top of the building by expansion bolts, which allows the seismic structure and heating pipeline to be suspended in the air. When the heating pipeline is subjected to vertical vibration impact, the impact force will act on the hanger 3, causing it to compress the damping spring shock absorber 2 and deform it. This provides vertical vibration protection for the heating pipeline. The structural design of the upper support 4 being directly connected to the hanger 3 allows the vertical impact force on the heating pipeline to be diffused and transmitted, thereby dispersing excessive impact force and preventing cracking at the pipeline connection due to excessive vibration.

[0032] The transverse buffer assembly 10 includes a housing 101 disposed on the top of the upper support 4. A buffer seat 102 connected to the hanger 3 is embedded in the inner wall of the housing 101. An air storage pipe 103 is wrapped around the outer side of the buffer seat 102, and a spacer ring 104 is wrapped around the outer side of the air storage pipe 103. An oil storage pipe 105 is disposed between the spacer ring 104 and the inner wall of the housing 101. When the hanger 3 is subjected to external force and shakes, or when the pressure of the hot water flow in the heating pipe is too high and impacts the heating pipe, the impact force on the hanger 3 or the heating pipe will act... The buffer seat 102 moves circumferentially within the housing 101 and compresses the gas storage pipe 103 to provide lateral primary buffering against the impact force. After the gas storage pipe 103 is excessively deformed under pressure, it drives the spacer ring 104 to move outward and compresses the oil storage pipe 105, causing it to be slowly compressed and deformed. This provides lateral secondary buffering for the buffer seat 102, thereby achieving an efficient buffering and shock absorption effect against the lateral impact force on the heating pipeline. This realizes a combined lateral and vertical vibration resistance effect for the heating pipeline.

[0033] The bottom of the lower bracket 6 is provided with a hollow and arc-shaped protective cover 7. The inner wall of the opening end of the protective cover 7 is provided with a screw groove, and the bottom edge of the lower bracket 6 is provided with a thread, so that the protective cover 7 can be screwed to the bottom of the lower bracket 6, thereby providing a sealing protection for the clamping rod 81.

[0034] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
