Abstract
Description
Technical Field
[0001] This invention relates to the field of building vibration isolation technology, and in particular to a vibration isolation trench filled with waste rubber particles. Background Technology
[0002] In the field of construction engineering, vibration interference is one of the key issues affecting the structural stability of buildings, the normal operation of equipment, and the comfort of living. With the acceleration of urban construction, the vibration energy generated by traffic loads, industrial production equipment operation, and construction vibration will propagate to the surrounding area in the form of elastic waves through the foundation soil, causing structural fatigue damage to neighboring buildings and a decrease in the accuracy of internal precision instruments.
[0003] As a passive vibration isolation device, vibration isolation trenches are widely used in vibration isolation projects between vibration sources and protected buildings due to their low cost, convenient construction, and minimal impact on existing buildings. The core principle is to excavate trenches along the vibration propagation path and utilize the spatial barrier effect of the trenches themselves, or to further dissipate vibration energy by filling the trenches with specific vibration isolation materials, thereby reducing the transmission of vibration to the protected area.
[0004] However, current rubber granule-filled vibration isolation trenches mostly rely on the elastic deformation of the rubber granules themselves to dissipate vibration energy. When faced with large-amplitude vibration, the deformation dissipation effect of the rubber granules weakens, and it cannot effectively absorb and dissipate the energy generated by large-amplitude vibration, resulting in a decrease in vibration isolation effect. It is difficult to meet the vibration isolation requirements under large-amplitude vibration scenarios, resulting in the vibration energy not being effectively dissipated and the vibration isolation effect being poor.
[0005] In view of this, this paper studies and improves upon existing problems, and provides a waste rubber granule-filled vibration isolation trench. The aim of this technology is to solve the problems and improve its practical value. Summary of the Invention

[0016] Preferably, the cylinder is provided with a torsion spring inside, one end of which is fixedly connected to the outer wall of the threaded rod, and the other end of which is fixedly connected to the inner wall of the cylinder.

[0019] Preferably, the bottom of the base plate is provided with a sliding groove, the slider slides inside the sliding groove, and one end of the drainage tube is connected to the inside of the sliding groove.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] 1. This invention transmits vibration energy to the bottom plate of the vibration isolation trench. The slide moves vertically up and down, causing the slide to move the vertical rod synchronously. This, in turn, causes the extrusion plate to move vertically. At this time, multiple disc springs installed between the extrusion plate and the cover plate will undergo compression or rebound deformation due to the movement of the extrusion plate, initially buffering and absorbing the vibration energy. Simultaneously, the movement of the vertical rod and the extrusion plate will also exert a squeezing effect on the rubber particles filled in the square cavity, forcing the rubber particles to squeeze, collide, and move in position within the square cavity. Friction will occur between the rubber particles due to relative motion, and contact friction will also occur between the rubber particles and the inner wall of the square cavity. These frictional actions and momentum exchange between the rubber particles will gradually convert the kinetic energy transmitted by vibration into heat and other forms of energy and dissipate them. This effectively compensates for the insufficient buffering capacity of the rubber particles themselves when dealing with large-amplitude vibrations, achieving efficient buffering and dissipation of vibration energy and ensuring the overall vibration isolation effect of the vibration isolation trench.
[0022] 2. This invention utilizes a sliding table to press against an elastic sheet. The elastic sheet deforms under the pressure of the sliding table, causing a slider to move laterally across the inner surface of the base plate. This slider compresses the first spring mounted on the outer wall of the piston rod. When the piston rod moves away from the suction and drainage pipes within the pumping cylinder, a negative pressure environment is created inside the pumping cylinder. Rainwater inside the concrete layer is drawn into the pumping cylinder through the suction pipe and squeezed out through the drainage pipe, thus achieving automatic extraction and discharge of rainwater from the concrete layer. This effectively prevents rainwater accumulation within the concrete layer, reduces prolonged contact between rainwater and the concrete layer inside the trench, and prevents corrosion of the concrete layer due to rainwater erosion, which could lead to a decrease in structural strength. This ensures the structural stability of the concrete layer and further extends the overall service life of the vibration isolation trench.
[0023] 3. This invention utilizes the vertical movement range generated by the slide table. During the downward movement of the slide table, a greater holding force is generated on the elastic sheet. The movement of the slider synchronously drives the moving plate to move closer to the outer wall of the vertical rod. As the moving plate approaches the vertical rod, it in turn drives the connecting rod inside the sleeve B to move towards the vertical rod, causing the friction plate to also move closer to the outer wall of the vertical rod. As the moving plate continues to approach the vertical rod, the squeezing force of the two friction plates on the vertical rod gradually increases. The increase in squeezing force increases the friction between the friction plate and the vertical rod. The increased friction can buffer and dissipate the impact force generated by the large-amplitude vibration of the vertical rod, so that the rubber particles do not need to absorb the large amount of kinetic energy required under the previous large-amplitude vibration, thereby reducing the frictional loss between the rubber particles caused by absorbing large kinetic energy and improving the service life of the rubber particles.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0037] See Figures 1 to 10 As shown, the present invention provides a waste rubber particle-filled vibration isolation trench, including a trench and a concrete layer 1 arranged inside the trench. The concrete layer 1 is provided with a bottom plate 3 inside, and a sliding table 4 is slidably provided inside the bottom plate 3. Multiple sets of H-shaped plates 5 and cover plates 6 are installed on the top of the sliding table 4. After the two sets of H-shaped plates 5 are connected, a square cavity is formed, and the square cavity is filled with rubber particles 7.
[0038] It should be noted that during the construction of the vibration isolation trench, the location is first determined next to the main vibration source such as the road or track. After the trench is excavated, the excavated soil is piled up next to the trench for later use. Then, a concrete layer 1 is laid at the bottom of the trench, and a base plate 3 is arranged along the length of the concrete layer 1. Rubber granules 7 are filled into the square cavity formed by the H-shaped plate 5 above the base plate 3. Then, a cover plate 6 is placed. Finally, the reserved soil is backfilled to the ground and compacted to complete the construction. When the vibration wave acts on the rubber granules 7, the rubber granules 7 will generate mutual compression, friction and relative motion. In this process, the vibration energy is converted into heat energy and other forms of energy and consumed. At the same time, the elastic deformation of the rubber granules 7 can further absorb some vibration energy, effectively weakening the intensity of the vibration wave, reducing the vibration impact of vibration sources such as roads and tracks on surrounding buildings, facilities or environment, and improving the user comfort and structural safety of the surrounding area.
[0039] The base plate 3 is provided with a buffer mechanism 8. The buffer mechanism 8 includes a vertical rod 81 fixedly inserted into the base plate 3. A pressing plate 82 is installed at the top of the vertical rod 81. Multiple sets of disc springs 83 are installed between the pressing plate 82 and the cover plate 6.
[0040] It should be noted that when the external environment vibrates, the vibration energy is transmitted to the base plate 3 of the vibration isolation trench, and then acts on the slide table 4 installed inside the base plate 3. Under the driving force of the longitudinal vibration wave, the slide table 4 moves up and down in the vertical direction. As the slide table 4 moves, it drives the vertical rod 81 to move synchronously. As a result, the vertical rod 81 drives the pressing plate 82 at its top to perform corresponding vertical movements. At this time, the multiple sets of disc springs 83 installed between the pressing plate 82 and the cover plate 6 will undergo compression or rebound deformation due to the movement of the pressing plate 82, initially buffering and absorbing the vibration energy. At the same time, the movement of the vertical rod 81 and the pressing plate 82 will also affect the other side. The rubber particles 7 filling the square cavity exert a squeezing effect, forcing the rubber particles 7 to squeeze, collide, and move in position within the square cavity. During this process, friction is generated between the rubber particles 7 due to relative motion, and contact friction also occurs between the rubber particles 7 and the inner wall of the square cavity. These frictional actions and momentum exchange between the rubber particles 7 gradually convert the kinetic energy transmitted by vibration into heat energy and other forms of energy and dissipate them. This effectively compensates for the insufficient buffering capacity of the rubber particles 7 when dealing with large amplitude vibrations, achieving efficient buffering and dissipation of vibration energy and ensuring the overall vibration isolation effect of the vibration isolation trench.
[0041] The base plate 3 is provided with a water pumping mechanism 9 on both sides. The water pumping mechanism 9 includes a water pumping cylinder 91 installed inside the base plate 3. A piston rod 92 slides inside the water pumping cylinder 91. A slider 97 is installed at one end of the piston rod 92. An elastic plate 96 is fixed at the bottom center of the slide table 4. One end of the elastic plate 96 is hinged to the top of the slider 97. One end of the water pumping cylinder 91 is connected to a water suction pipe 93 and a water discharge pipe 94.
[0042] It should be noted that when the slide table 4 moves up and down along the outer wall of the vertical rod 81, the slide table 4 will simultaneously exert a pressing force on the elastic plate 96 fixed at the center of its bottom. After being pressed by the slide table 4, the elastic plate 96 deforms, and this deformation will drive the slider 97 to move laterally on the inner surface of the base plate 3. During the lateral movement, the slider 97 will drive the piston rod 92 to move laterally inside the pumping cylinder 91. At this time, the slider 97 will compress the first spring sleeved on the outer wall of the piston rod 92. When the first spring and the elastic plate 96 rebound after the pressure is released, they will drive the piston rod 92 to move laterally back and forth inside the pumping cylinder 91. When the piston rod 92 moves away from the suction pipe 93 and the drain pipe 94 inside the pumping cylinder 91, a... In a negative pressure environment, under the one-way flow guidance of the one-way valves at the connection between the suction pipe 93 and the pumping cylinder 91, and at the connection between the drain pipe 94 and the pumping cylinder 91, rainwater inside the concrete layer 1 will be sucked into the pumping cylinder 91 through the suction pipe 93. Subsequently, when the piston rod 92 moves towards the suction pipe 93 and the drain pipe 94, the rainwater in the pumping cylinder 91 will be squeezed and discharged out of the concrete layer 1 through the drain pipe 94. This achieves automatic extraction and discharge of rainwater inside the concrete layer 1, effectively preventing rainwater from accumulating inside the concrete layer 1, reducing the long-term contact between rainwater and the concrete layer 1 inside the trench, and preventing the concrete layer 1 from being corroded by rainwater, which would lead to a decrease in structural strength. This ensures the structural stability of the concrete layer 1 and further extends the overall service life of the vibration isolation trench.
[0043] The vertical rod 81 is provided with a pressing mechanism 10 on both sides. The pressing mechanism 10 includes a movable plate 101 fixed on one side of the slider 97. A sleeve B102 is embedded in the top of the movable plate 101. A connecting rod 103 slides inside the sleeve B102. A friction plate 104 is fixed at one end of the connecting rod 103.
[0044] It should be noted that when the external vibration amplitude is large, the vertical movement amplitude of the slide table 4 will increase significantly. During the downward movement of the slide table 4, it will exert a greater holding force on the elastic plate 96, pushing the elastic plate 96 to deform further and causing the slider 97 to move more significantly. The movement of the slider 97 will simultaneously drive the moving plate 101 to move closer to the outer wall of the vertical rod 81. As the moving plate 101 moves closer to the vertical rod 81, the sleeve B102 embedded at its top will move synchronously with the moving plate 101, thereby driving the connecting rod 103 inside the sleeve B102 to move towards the vertical rod 81, so that the friction plate 104 will also move closer to the outer wall of the vertical rod 81. As the moving plate 101 continues to move... As the vertical rod 81 approaches, the squeezing force of the two friction plates 104 on the vertical rod 81 gradually increases. The increase in squeezing force increases the friction between the friction plates 104 and the vertical rod 81. The increased friction can buffer and dissipate the impact force generated by the large vibration of the vertical rod 81. The friction can also buffer and dissipate the impact force on the slide table 4. When the extrusion plate 82 moves up and down inside the square cavity, it can effectively reduce the power transmitted from the vertical rod 81 to the extrusion plate 82 and finally applied to the rubber particles 7. This means that the rubber particles 7 do not need to absorb the large amount of kinetic energy required under the previous large-amplitude vibration, thereby reducing the frictional loss between the rubber particles 7 caused by absorbing large kinetic energy and improving the service life of the rubber particles 7.
[0045] The top of the cover plate 6 is provided with an oil spraying mechanism 11, and the outer wall of the vertical rod 81 is provided with a lubrication mechanism 12.
[0046] See Figures 3 to 4 As shown, a first spring is sleeved on the outer wall of the piston rod 92. One end of the first spring is fixedly connected to one end of the pumping cylinder 91, and the other end of the first spring is fixedly connected to the side wall of the slider 97. When the slider 97 is pushed laterally by the elastic plate 96 and compresses the first spring, the spring rebounds and can drive the slider 97 and the piston rod 92 to move in opposite directions, ensuring that the piston rod 92 slides stably back and forth in the pumping cylinder 91, and ensuring that the pumping mechanism 9 continuously and efficiently pumps water.
[0047] See Figure 4 As shown, a one-way valve is installed at the connection between the suction pipe 93 and the pumping cylinder 91, and a one-way valve is installed at the connection between the drain pipe 94 and the pumping cylinder 91. A filter screen is provided at the suction end of the suction pipe 93. The one-way valve can control the water flow to flow only from the suction pipe 93 into the pumping cylinder 91 and from the pumping cylinder 91 to the drain pipe 94, respectively, to avoid backflow of water and ensure the orderly operation of the pumping process. The filter screen at the suction end of the suction pipe 93 can filter impurities in the water and prevent impurities from entering the pumping cylinder 91 and clogging the pipe.
[0048] See Figures 5 to 6As shown, a second spring is provided inside the sleeve B102. One end of the second spring is fixedly connected to one end of the connecting rod 103, and the other end of the second spring is fixedly connected to the inner wall of the sleeve B102. The deformation of the second spring adapts to the slight displacement of the connecting rod 103, thereby avoiding wear caused by the rigid contact between the friction plate 104 and the vertical rod 81.
[0049] See Figures 7 to 8 As shown, the oil injection mechanism 11 includes an oil reservoir 111 installed at the top of the cover plate 6, a connector 112 installed on the outer wall of the drain pipe 94, a threaded rod 113 rotatably provided inside the connector 112, a blade 114 installed on the outside of the threaded rod 113, a cylinder 115 fixed between the oil reservoir 111 and the connector 112, a circular plate 116 threadedly connected to the outer wall of the threaded rod 113, a push rod 117 fixed at one end of the circular plate 116, a push plate 118 fixed at one end of the push rod 117 that passes through to the oil reservoir 111, an oil injection pipe 110 connected to the outer wall of the oil reservoir 111, and a nozzle installed at one end of the oil injection pipe 110 that passes through to the bottom of the cover plate 6.
[0050] It should be noted that when the water accumulated in the concrete layer 1 is discharged through the drain pipe 94, the flowing water will impact the blades 114 inside the joint 112 on the outer wall of the drain pipe 94. Driven by the impact force of the water flow, the blades 114 begin to rotate. The rotation of the blades 114 will synchronously drive the threaded rod 113 to rotate. When the threaded rod 113 rotates, the circular plate 116 moves linearly along the inner wall of the cylinder 115 under the action of the threaded transmission. The linear motion of the circular plate 116 can drive the push plate 118 to move towards the inside of the oil storage tank 111 through the push rod 117. The push plate 118 moves towards the inside of the oil storage tank 111. When the device moves within the cavity, it will exert a squeezing effect on the lubricating oil stored in the oil reservoir 111. Under the squeezing force, the lubricating oil in the oil reservoir 111 will flow into the oil spray pipe 110. The lubricating oil in the oil spray pipe 110 will be precisely sprayed onto the surface of the rubber particles 7 inside the square cavity through the nozzle, thereby achieving automatic lubrication of the rubber particles 7. The oil film formed by the metered oil spray can form a flexible buffer layer between the particles, reducing the frictional loss between the rubber particles 7 and between the rubber particles 7 and the inner wall of the square cavity, further extending the service life of the rubber particles 7, and ensuring the long-term stable vibration isolation performance of the vibration isolation trench.
[0051] See Figure 8 As shown, a torsion spring 119 is provided inside the cylinder 115. One end of the torsion spring 119 is fixedly connected to the outer wall of the threaded rod 113, and the other end of the torsion spring 119 is fixedly connected to the inner wall of the cylinder 115. When the water flow impacts the blade 114, it drives the threaded rod 113 to rotate and torsion spring 119. The torsion spring 119 rebounds and drives the threaded rod 113 to rotate in the opposite direction, thereby resetting the circular plate 116 and the push plate 118 to ensure circulating oil injection.
[0052] See Figures 9 to 10As shown, the lubrication mechanism 12 includes a collection groove 121 inside the extrusion plate 82. A docking cylinder 122 is installed through the inside of the collection groove 121. A drainage pipe 123 is installed at the bottom of the bottom plate 3. Through holes are opened on the surfaces of the docking cylinder 122 and the drainage pipe 123. The docking cylinder 122 and the drainage pipe 123 are inserted and matched.
[0053] See Figure 9 As shown, the collection tank 121 is tapered, and the surface of the extrusion plate 82 has multiple sets of through holes.
[0054] See Figure 9 As shown, a groove is provided at the bottom of the inner side of the base plate 3, the slider 97 slides inside the groove, and one end of the drainage pipe 123 is connected to the inside of the groove.
[0055] It should be noted that during the process of the oil spraying mechanism 11 spraying lubricating oil onto the surface of the rubber particles 7 inside the square cavity, some excess lubricating oil that is not completely absorbed by the rubber particles 7 will flow downwards under the action of gravity. This excess lubricating oil will flow into the collection groove 121 opened inside the extrusion plate 82 through the through holes on the surface of the extrusion plate 82. Since the collection groove 121 is conical, the conical structure can play a role in converging and guiding the flowing lubricating oil, avoiding the accumulation of lubricating oil in the collection groove 121. During the operation of the buffer mechanism 8, the extrusion plate 82 will move up and down reciprocally with the vertical rod 81. When the extrusion plate 82 moves up and down, it will drive the docking cylinder 122 to move up and down synchronously. The movement causes the drainage tube 123 to be intermittently inserted into the docking cylinder 122. When the drainage tube 123 is inserted into the docking cylinder 122, the through holes of the two are aligned with each other, thereby connecting the drainage tube 123 and the docking cylinder 122. At this time, the lubricating oil collected in the collection tank 121 will flow into the drainage tube 123 along the through hole of the docking cylinder 122. The lubricating oil in the drainage tube 123 will further flow into the slide groove to lubricate the slider 97 in the slide groove, thereby effectively reducing the frictional resistance between the slider 97 and the slide groove, making the slider 97 slide more smoothly in the slide groove. Not only will it not produce sharp noise due to friction, but it will also reduce the wear of the slider 97 during the sliding process.
[0056] Working principle: When constructing a vibration isolation trench, first select a location next to the main vibration source such as a road or track, excavate the trench, and pile the excavated original soil next to the trench for later use. Then, lay a concrete layer 1 at the bottom of the trench, arrange a base plate 3 along the length of the concrete layer 1, fill the square cavity formed by the H-shaped plate 5 above the base plate 3 with rubber granules 7, then arrange a cover plate 6, and finally backfill the ground with the reserved original soil and compact it to complete the construction.
[0057] When the external environment vibrates, the vibration energy is transmitted to the bottom plate 3 of the vibration isolation trench, and then acts on the slide 4 installed inside the bottom plate 3. Under the driving force of the longitudinal vibration wave, the slide 4 moves up and down in the vertical direction. As the slide 4 moves, it drives the vertical rod 81 to move synchronously. As a result, the vertical rod 81 drives the extrusion plate 82 at its top to make corresponding vertical movements. At this time, the multiple disc springs 83 installed between the extrusion plate 82 and the cover plate 6 will be compressed or rebounded due to the movement of the extrusion plate 82, which initially buffers and absorbs the vibration energy. At the same time, the movement of the vertical rod 81 and the extrusion plate 82 will also exert a squeezing effect on the rubber particles 7 filled in the square cavity, forcing the rubber particles 7 to squeeze, collide and move in position inside the square cavity. During this process, friction will be generated between the rubber particles 7 due to relative movement.
[0058] When the slide table 4 moves up and down along the outer wall of the vertical rod 81, it simultaneously presses against the elastic plate 96 fixed at the center of its bottom. The elastic plate 96 deforms under the pressure of the slide table 4, causing the slider 97 to move laterally on the inner surface of the base plate 3. During this lateral movement, the slider 97 moves synchronously with the piston rod 92 inside the pump cylinder 91. At this time, the slider 97 compresses the first spring sleeved on the outer wall of the piston rod 92. When the first spring and the elastic plate 96 rebound after the pressure is released, they cause the piston rod 92 to move laterally within the pump cylinder. The piston rod 92 moves in a reciprocating horizontal motion inside the pumping cylinder 91. When the piston rod 92 moves away from the suction pipe 93 and the drain pipe 94 inside the pumping cylinder 91, a negative pressure environment is formed inside the pumping cylinder 91. At this time, under the one-way flow guidance action of the one-way valve at the connection between the suction pipe 93 and the pumping cylinder 91 and the one-way valve at the connection between the drain pipe 94 and the pumping cylinder 91, the rainwater inside the concrete layer 1 will be sucked into the pumping cylinder 91 through the suction pipe 93. Then, when the piston rod 92 moves closer to the suction pipe 93 and the drain pipe 94, the rainwater inside the pumping cylinder 91 will be squeezed and discharged out of the concrete layer 1 through the drain pipe 94.
[0059] When the external vibration amplitude is large, the vertical movement amplitude of the slide table 4 will increase significantly. During the downward movement of the slide table 4, it will exert a greater holding force on the elastic plate 96, pushing the elastic plate 96 to deform further and causing the slider 97 to move more significantly. The movement of the slider 97 will simultaneously drive the moving plate 101 to move closer to the outer wall of the vertical rod 81. During the process of the moving plate 101 approaching the vertical rod 81, the sleeve B102 embedded at its top will move synchronously with the moving plate 101, thereby driving the connecting rod 103 inside the sleeve B102 to move towards the vertical rod 81, so that the friction plate 104 will also move closer to the outer wall of the vertical rod 81. As the moving plate 101 continues to approach the vertical rod 81, the squeezing force of the two friction plates 104 on the vertical rod 81 will gradually increase. The increase in squeezing force will increase the friction between the friction plate 104 and the vertical rod 81.
[0060] When the water accumulated in the concrete layer 1 is discharged through the drain pipe 94, the flowing water will impact the blades 114 inside the joint 112 on the outer wall of the drain pipe 94. Driven by the impact force of the water flow, the blades 114 start to rotate. The rotation of the blades 114 will synchronously drive the threaded rod 113 to rotate. When the threaded rod 113 rotates, the circular plate 116 moves linearly along the inner wall of the cylinder 115 under the action of the threaded transmission. The linear movement of the circular plate 116 can drive the push plate 118 to move towards the inside of the oil storage tank 111 through the push rod 117. When the push plate 118 moves inside the oil storage tank 111, it will squeeze the lubricating oil stored in the oil storage tank 111. Under the action of the squeezing force, the lubricating oil in the oil storage tank 111 will flow into the oil spray pipe 110. The lubricating oil in the oil spray pipe 110 will be accurately sprayed onto the surface of the rubber particles 7 inside the square cavity through the nozzle.
[0061] During the process of the oil spraying mechanism 11 spraying lubricating oil onto the surface of the rubber particles 7 inside the square cavity, some excess lubricating oil that is not completely absorbed by the rubber particles 7 will flow downwards under the action of gravity. This excess lubricating oil will flow into the collection groove 121 opened inside the extrusion plate 82 through the through holes on the surface of the extrusion plate 82. During the operation of the buffer mechanism 8, the extrusion plate 82 will move up and down with the vertical rod 81. When the extrusion plate 82 moves up and down, it will drive the docking cylinder 122 to move up and down synchronously, so that the drainage pipe 123 is intermittently inserted into the docking cylinder 122. When the drainage pipe 123 is inserted into the docking cylinder 122, the through holes of the two are aligned with each other, thereby realizing the connection between the drainage pipe 123 and the docking cylinder 122. At this time, the lubricating oil gathered in the collection groove 121 will flow into the drainage pipe 123 along the through hole of the docking cylinder 122. The lubricating oil in the drainage pipe 123 will further flow into the slide groove to lubricate the slider 97 in the slide groove.
