Description

Technical Field

[0001] This invention relates to the field of rail transit technology, specifically to a shock-absorbing buffer support for rail transit thermal control room equipment. Background Technology

[0002] The thermal control room used in rail transit differs from that in thermal power plants. Instead, the functions of the traditional thermal control room are distributed among the environmental control and electrical control room, traction substation, heat exchange station, and vehicle control room. Due to the significant vibrations generated when the subway enters the station, the traditional installation method uses vibration-damping buffer supports for the equipment in the control room. However, existing buffer supports have certain drawbacks in actual use. First, existing buffer bases, whether using multi-layer rubber or springs for shock absorption, tend to have poor heat dissipation performance at the bottom of the equipment, thus affecting the normal operation of the equipment. Second, the energy generated by vibration is naturally dissipated, resulting in energy waste. Therefore, it is necessary to improve the existing buffer supports to address these problems.

[0012] Beneficial effects This invention provides a shock-absorbing buffer support for thermal control room equipment in rail transit. Compared with the prior art, it has the following advantages: (1) By setting up a shock-absorbing mechanism, the equipment can be installed on the support plate using the fixed column. The rubber column and buffer rod can be used for shock absorption. At the same time, the fixed cover, air hole and fixed pipe can be used to facilitate air flow by cooperating with the gap between the rubber columns. During the buffering process, the fan blade drives the spiral rod to descend. Through the spiral abutment between the spiral rod and the fixed frame, the spiral rod drives the fan blade to rotate. This allows the air to be blown evenly to the bottom of the equipment through the fixed pipe, fixed cover and air hole. This can improve the heat dissipation performance of the bottom of the equipment and recover the energy generated by vibration, thereby avoiding the problem of energy waste.

[0013] (2) By setting auxiliary components, the screw rod can be balanced by the cooperation of the fixed sleeve and the sliding tooth column. When stationary, the fixed sleeve can wrap the screw rod so that dust and impurities do not adhere to its surface, thus affecting its spiral contact. At the same time, by utilizing the transmission ratio between the fixed tooth column, the transmission gear, the drive gear and the sliding tooth column, the speed of the fan blade can be increased, thereby increasing the air intake inside the fixed tube, thus improving the heat dissipation effect on the bottom of the equipment.

[0014] (3) By setting up an air storage component, when the piston rod rises inside the solid cylinder, outside air enters the solid cylinder through one of the one-way valve pipes, and when the piston rod falls, it can compress the air into the air box, thereby compressing and storing outside air. When the equipment has a heat dissipation requirement, the compressed air inside the air box can be blown into the solid cover through the spring tube, thereby dissipating heat at the bottom of the equipment. The filter cartridge is connected to the one-way valve pipe by a thread, which facilitates the replacement of the filter element. At the same time, the filter element setting can ensure the cleanliness of the compressed air to avoid the problem of the air flow path being blocked.

[0015] (4) By setting up a pressure-grading component, the magnetic force and the elastic extension of the pressure-holding rod are used to compress the output end of the pressure-holding rod when vibration occurs. This compression of the piston rod into the solid cylinder is achieved through the elastic force and magnetic force, thereby storing the air inside the solid cylinder in the compressed air box. Furthermore, the locking action of the block and the slot allows the piston rod to gradually compress the air inside the solid cylinder when the energy generated by the vibration is small, thus avoiding the problem of not being able to compress the air into the solid cylinder.

The outer surface of the filter plate 13 is fixedly connected to the inside of the solid tube 5. The shaft end of the fan blade 6 is fixedly connected to the brush plate 14, which is provided with bristles. As the brush plate 14 rotates with the fan blade 6, the bristles can clean the surface of the filter plate 13, preventing dust accumulation and clogging of the filter holes, thereby avoiding affecting the air flow. The outer surface of the brush plate 14 is movably connected to the inside of the solid tube 5 and the outer surface of the filter plate 13.

[0021] An auxiliary component 8 is provided on the outside of the screw rod 7.

In a preferred embodiment, the sliding toothed column 82 can slide through the fixed sleeve 81 via a metal sealing ring (not shown in the figure), and the metal sealing ring is rotatably connected through the body of the fixed sleeve 81. At the same time, the inner ring of the sealing ring is provided with teeth that are adapted to the sliding toothed column 82 to fill the gaps between the teeth of the sliding toothed column 82 and prevent external dust. Inside the fixed sleeve 81, one end of the sliding tooth column 82 is fixedly connected to the shaft end of the fan blade 6, and the other end of the sliding tooth column 82 is rotatably connected to a pin 83. The pin 83 axially fixes one end of the spiral rod 7 to one end of the sliding tooth column 82. One end of the pin 83 is fixedly connected to one end of the spiral rod 7.

The outer surface of the spiral rod 7 is movably connected to the body of the ratchet 84, and the outer surface of the ratchet 84 is rotatably connected to the body of the fixed frame 12.

[0022] A fixed toothed column 85 is fixedly connected through the outer surface of the ratchet 84. The connection between the fixed toothed column 85 and the fixed frame 12 is provided with an axial limiting measure (not shown in the figure). The outer surface of the fixed toothed column 85 is rotatably connected through the body of the fixed frame 12. A rotating rod 86 is provided on the outside of the fixed toothed column 85. The rotating rod 86 plays a supporting and transmission role. The two ends of the rotating rod 86 are respectively embedded and rotatably connected to the inside of the fixed sleeve 81 and the outer surface of the fixed frame 12. Two transmission gears 87 are fixedly connected through the outer surface of the rotating rod 86. The outer surface of one transmission gear 87 meshes with the outer surface of the fixed toothed column 85. The outer surface of the other transmission gear 87 meshes with a drive gear 88. The shaft end of the drive gear 88 is embedded and rotatably connected to the inside of the fixed sleeve 81. There is a certain multiple of transmission ratio between the fixed toothed column 85, the two transmission gears 87, the drive gear 88 and the sliding toothed column 82, thereby increasing the rotational speed of the fan blade 6 and increasing the air intake of the fixed pipe 5. The outer surface of the drive gear 88 meshes with the outer surface of the sliding toothed column 82.

[0023] An air storage assembly 4 is provided on the outside of the solid cover 3. The air storage assembly 4 includes an air box 41, which is filled with high-pressure air. The high-pressure air is blown onto the equipment, which can both dissipate heat and dry the outside of the equipment to prevent moisture damage. The outer surface of the air box 41 is fixedly connected to the outer surface of the base 1. A solid cylinder 42 is provided on the outside of the air box 41. The two ends of the solid cylinder 42 are closed to provide a sealing effect. A piston rod 43 is slidably connected through the inside of the solid cylinder 42. The sliding of the piston rod 43 can compress the air inside the solid cylinder 42. There are two one-way valve pipes 45 that are connected internally. The two one-way valve pipes 45 allow outside air to flow into the air box 41 through the solid cylinder 42 for storage. One end of one one-way valve pipe 45 is connected to the inside of the air box 41. A spring tube 46 is connected internally to the air box 41. The extension and retraction of the spring tube 46 facilitates the up and down movement of the solid cover 3. A solenoid valve that is electrically connected to an external control circuit is provided on the end of the spring tube 46 near the air box 41. The solenoid valve is used to control the discharge of compressed air inside the air box 41. One end of the spring tube 46 is connected internally to the inside of the solid cover 3.

[0024] Another one-way valve tube 45 is movably connected to a filter element 47 at one end. The filter element 47 can filter the air entering the air box 41 to prevent dust, impurities, and moisture from entering and causing blockage and corrosion. The outer surface of the filter element 47 is fitted with a filter cylinder 48. The filter cylinder 48 can not only support the filter element 47, but also facilitate air flow through its own filter holes. At the same time, the filter element 47 can be easily disassembled and replaced through the threaded connection with the one-way valve tube 45. The inside of the filter cylinder 48 is threadedly connected to the outer surface of the other one-way valve tube 45.

[0025] A pressure-grading unit 44 is provided on the body of the piston rod 43. The pressure-grading unit 44 includes a pressure-holding rod 441, which is made of a spring rod. Through its own elastic force, the pressure-holding rod 441 can push the piston rod 43 to compress the air inside the solid cylinder 42. One end of the pressure-holding rod 441 is fixedly connected to the outer surface of the solid cover 3. A magnetic pressure plate 442 is fixedly connected to the output end of the pressure-holding rod 441. A magnetic demagnetizing plate 443 is movably connected to the outer surface of the magnetic pressure plate 442. Both the magnetic pressure plate 442 and the magnetic demagnetizing plate 443 are made of strong magnets. Through magnetic attraction, they can drive the piston rod 43 to slide upward and reset, so as to continuously compress the air. The outer surface of the magnetic demagnetizing plate 443 is fixedly connected to the output end of the piston rod 43. As a preferred embodiment, a compression spring is provided between the magnetic demagnetizing plate 443 and the solid cylinder 42, and the compression spring is sleeved on the outside of the piston rod 43. The piston rod 43 is compressed by the spring rebound. The piston rod 43 rises and resets to continue compressing air. At this time, the magnetic repulsion between the magnetic plate 442 and the anti-magnetic plate 443 enhances the pushing effect on the piston rod 43, thus facilitating the step-by-step compression of the piston rod 43. The piston rod 43 has a slot 444, which is longitudinally and equidistantly arranged in multiple slots to accommodate the step-by-step compression of the piston rod 43. An anti-block 445 is engaged inside the slot 444, and a reset rod 446 is fixedly connected to the outer surface of the anti-block 445. The reset rod 446 is made of a spring rod, which can spring back to allow the anti-block 445 to slide into the slot 444 to longitudinally limit the piston rod 43. The output end of the reset rod 446 is fixedly connected to the inside of the fixed cylinder 42. The outer surface of the anti-block 445 has a chamfer. When the piston rod 43 descends, the chamfer squeezes the anti-block 445, and the anti-block 445 slides inside the slot 444, thus facilitating the smooth descent of the piston rod 43.

[0026] The piston rod 43 has two annular grooves 447. The distance between the annular groove 447 and the slot 444 is the same as the distance between two adjacent slots 444. The interiors of the two annular grooves 447 are connected by a vertical groove 448. The abutment 445 can slide from the interior of one annular groove 447 into the interior of the other annular groove 447 through the vertical groove 448. The vertical groove 448 is formed on the piston rod 43. The outer surface of the abutment 445 is slidably connected to the interior of the vertical groove 448 and the two annular grooves 447 respectively. A rotary cylinder 449 is fixedly connected to the outer surface of the magnetic plate 443. The rotary cylinder 449 is electrically connected to an external control circuit. By controlling the rotation of the piston rod 43, the relative position of the abutment 445 and the slot 444 can be changed, thereby facilitating the piston rod 43 to rise and reset. The output end of the rotary cylinder 449 is fixedly connected to the piston rod 43.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] Working Principle: The core of this anti-vibration buffer support for the thermal control room equipment of rail transit achieves anti-vibration buffering through a vibration damping mechanism. Simultaneously, it works in conjunction with auxiliary components 8, air storage components 4, and pressure-grading units 44 to recover and utilize the energy generated by vibration, converting it into heat dissipation power at the bottom of the equipment. This solves the problem of poor heat dissipation in traditional supports and avoids the natural waste of vibration energy. The various components work together to achieve an integrated function of anti-vibration, heat dissipation, and energy recovery. Its specific working principle is as follows: During the equipment installation phase, the rail transit thermal control room equipment can be stably fixed on the support plate 2 through the fixed column 15 on one side and the mounting holes 16 on its outer surface. The filter screen 17 on the outer surface of the fixed column 15 can seal the gaps between the fixed columns 15, preventing external dust from entering and contaminating or clogging the air holes 11 on the support plate 2, thus providing a clean channel for subsequent airflow. When the subway enters the station and vibrates, the vibration force is transmitted to the support plate 2. The buffer rod 9 (spring rod material) connected to the base 1 on the outer surface of the support plate 2 will elastically expand and contract. At the same time, the rubber column 10 (high hardness rubber material) on one side of the support plate 2 will elastically deform. The two work together to initially dampen the vibration and reduce the impact of vibration on the equipment in the room. While providing shock absorption, the support plate 2 will move up and down with the vibration, which in turn will drive the fixed cover 3 to move up and down synchronously. The shock absorption mechanism and the auxiliary component 8 will start to work together to realize energy recovery and wind power heat dissipation. When the fixed cover 3 moves down, it will drive the fan blade 6 and the sliding tooth column 82 and the spiral rod 7 at the shaft end to move down synchronously. The spiral rod 7 is in the shape of a DNA helix, and the fixed frame 12 that penetrates it provides a resisting force for the spiral rod 7. During the downward movement, the spiral rod 7 and the fixed frame 12 will make spiral contact, thereby driving the spiral rod 7 to rotate in one direction. The ratchet 84 can ensure the unidirectional rotation of the spiral rod 7. The rotation characteristic is to avoid reverse rotation affecting power transmission; the rotation of the screw rod 7 drives the fixed tooth column 85 to rotate through the ratchet 84. The fixed tooth column 85 is driven by the transmission action of two transmission gears 87 and the rotating rod 86, as well as the meshing of the drive gear 88 with the transmission gear 87 and the sliding tooth column 82, so that the sliding tooth column 82 drives the fan blade 6 to rotate to pump in outside air. Furthermore, through the meshing of the sliding tooth column 82, the drive gear 88, and the fixed transmission ratio between the transmission gear 87 and the fixed tooth column 85, the rotation speed of the fan blade 6 will be further increased, thereby increasing the air intake inside the fixed pipe 5. When the fan blade 6 rotates at high speed, outside air enters through the solid pipe 5. The filter plate 13 inside the solid pipe 5 can perform preliminary filtration of the air to prevent large particles of impurities from entering. At the same time, the brush plate 14 at the shaft end of the fan blade 6 rotates synchronously with the fan blade 6. The bristles on the brush plate 14 will clean the surface of the filter plate 13 and the inner wall of the solid pipe 5 to prevent dust from accumulating and clogging the filter holes and channels. After the filtered air is collected by the solid cover 3, it is evenly blown to the bottom of the equipment through the air holes 11 on the support plate 2. The air holes 11 and the rubber columns 10 are staggered and matched with the gaps between the rubber columns 10 to allow the air to flow fully at the bottom of the equipment, quickly remove the heat generated by the operation of the equipment, and achieve efficient heat dissipation. When the fixed cover 3 moves downward, it pushes the pressure holding rod 441 (made of spring rod material) to retract. The magnetic plate 442 at the output end of the pressure holding rod 441 and the antimagnetic plate 443 at the output end of the piston rod 43 are in contact with each other. Both are made of strong magnet material. The magnetic attraction force, together with the elastic force of the pressure holding rod 441, pushes the piston rod 43 to slide into the solid cylinder 42. The slot 444 on the piston rod 43 engages with the block 445 inside the solid cylinder 42. The block 445 is lifted by the reset rod 446 (made of spring rod material). Provides support. When the vibration energy is small, during the downward movement of the piston rod 43, the abutment 445 will engage with the slots 444 at different heights in sequence, thereby gradually compressing the air inside the solid cylinder 42 and avoiding the problem of insufficient vibration energy to complete air compression. The rotary cylinder 449 can drive the piston rod 43 to rotate, causing the abutment 445 to slide along the vertical groove 448 between the two annular grooves 447, changing the relative position of the abutment 445 and the slots 444, which facilitates the piston rod 43 to rise and reset. When the piston rod 43 slides inside the solid cylinder 42, the two one-way valve pipes 45 on the solid cylinder 42 realize the one-way flow of air: when the piston rod 43 rises, the outside air enters the solid cylinder 42 through one of the one-way valve pipes 45. The filter element 47 at the end of the one-way valve pipe 45 will finely filter the air, filter out dust, impurities and moisture, and avoid channel blockage and component corrosion. When the piston rod 43 descends and compresses, the air inside the solid cylinder 42 is forced into the air box 41 through the other one-way valve pipe 45 to complete the air compression and storage. When the equipment has a continuous heat dissipation requirement or insufficient vibration energy, the solenoid valve is opened, and the compressed air inside the air box 41 enters the solid cover 3 through the spring tube 46, and then blows to the bottom of the equipment through the air hole 11 to achieve continuous heat dissipation. At the same time, the high-pressure air can also dry the outside of the equipment to prevent moisture from damaging the equipment. After the vibration dissipates, the elastic components such as the buffer rod 9, rubber column 10, and pressure holding rod 441 elastically reset, driving the support plate 2, solid cover 3, piston rod 43 and other components back to their initial positions, preparing for the next vibration buffering, energy recovery and air compression. The entire support achieves the cyclical work of shock absorption, heat dissipation and cooling, and energy recovery, adapting to the continuous vibration environment of rail transit stations and ensuring the stable operation of thermal control room equipment.
