Description

Technical Field

[0001] This invention belongs to the field of energy-saving light pole technology, and particularly relates to a vibration reduction device for energy-saving light poles. Background Technology

[0002] Light poles on bridges can resonate or sway under wind or other external forces. This resonance or swaying accelerates the fatigue of related structures, thus affecting their service life. For example, in patent 200910096497.0, existing bridge light poles have damping balls installed at the top to reduce vibration. However, the use of damping balls cannot control the damping force, and the damping force cannot be adjusted according to the degree of light pole vibration.

[0003] To reduce dust particles in urban air, a misting sprinkler system is installed on light poles to meet environmental protection requirements. This system sprays mist into the air when air quality is poor, effectively removing dust. Water, the spray medium in the system, is also an excellent buffer and vibration damping medium. Water can effectively buffer and absorb vibrations from the light poles to a certain extent, and the damping force generated by the water in absorbing these vibrations can be flexibly adjusted by regulating the amount of water.

[0004] This invention designs a vibration damping device for energy-saving light poles, which effectively absorbs the vibrations generated by the light poles through water to solve the above problems. Summary of the Invention

[0005] Therefore, it is necessary to address the problems existing in current energy-saving light pole vibration damping devices by providing a vibration damping device for energy-saving light poles. In this invention, the main vibration damping component, located at the top of the light pole, utilizes water to effectively buffer, dampen, and absorb the vibrations generated by the light pole. The water in the main vibration damping component does not collide with the light pole during its buffering and absorption of vibrations, and the main vibration damping component is more reliable because it will not collide with or damage the light pole during the absorption and buffering process. The main vibration damping component in this invention can adjust the amount of water within it through its cooperation with a water level regulating component, thereby adjusting the ability of the main vibration damping component to absorb and buffer the light pole vibrations according to the amplitude of the light pole vibration. This, in turn, adjusts the damping force generated by the main vibration damping component during light pole vibration, so that the damping force generated by the main vibration damping component increases or decreases with the increase or decrease of the light pole vibration amplitude. In this invention, the atomizing nozzles installed on the crossbar near the top of the lamp post use water from the main vibration damping assembly to atomize and spray the air for dust removal. Meanwhile, the driving assembly in this invention, under the action of water pressure in the water supply pipe, transmits the water pressure in the water supply pipe to the water level regulating assembly through the pipeline system and drives the water level regulating assembly to adjust and replenish the water volume in the main vibration damping assembly, thereby achieving three uses for one water source.

The two ends of the cylinder of the electric push rod 630 are respectively fixed to the second fixing frame 631 inside the lamp post 101 by the second clamp 632. The second clamp 632 is connected to the second fixing frame 631 by bolts.

[0068] In a further embodiment, such as Figure 1 , Figure 11 , Figure 12As shown, the wall of the lamp post 101 is provided with an inlet 102 for installing the reversing valve assembly 604 and the electric push rod 630 into the lamp post 101. A cover plate 103 is installed at the inlet 102 by bolts. A flange 104 is provided at the lower end of the lamp post 101. The flange 104 is fixed to the concrete base 107 by anchor bolts 111.

[0069] In this invention, the main vibration damping component 200, located at the top of the lamp post 101, effectively buffers and absorbs the vibrations generated by the lamp post 101 using water. The water in the main vibration damping component 200 does not collide with the lamp post 101 during its buffering and absorption of vibrations, and the main vibration damping component 200 is more reliable because it will not collide with or damage the lamp post 101 during the absorption and buffering process. The main vibration damping component 200 can adjust the amount of water within it through its cooperation with the water level regulating component 400, thereby adjusting its ability to absorb and buffer the vibrations of the lamp post 101 according to the vibration amplitude. This, in turn, adjusts the damping force of the main vibration damping component 200 in absorbing and buffering the vibrations of the lamp post 101, so that the damping force generated by the main vibration damping component 200 increases or decreases with the increase or decrease of the vibration amplitude of the lamp post 101. In this invention, the atomizing nozzle 640 installed on the crossbar 106 near the top of the lamp post 101 uses water from the main vibration damping component 200 to atomize and spray the air for dust removal. Meanwhile, the driving component 500 in this invention, under the action of water pressure in the water supply pipe 113, transmits the water pressure in the water supply pipe 113 to the water level regulating component 400 through the pipeline system 600, and drives the water level regulating component 400 to regulate and replenish the water volume in the main vibration damping component 200, thereby realizing three uses of one water source.

[0070] The operation flow of this invention is as follows:

[0071] In the initial state, such as Figure 18 As shown in (c), in the reversing valve assembly 604, the fifth piston 622 closes the seventh water hole 608 and the eighth water hole 609 but opens the ninth water hole 610 and the tenth water hole 611; the sixth piston 623 closes the ninth water hole 610 and the tenth water hole 611; the seventh piston 624 closes the eleventh water hole 612 and the twelfth water hole 613 but opens the thirteenth water hole 614 and the fourteenth water hole 615; the eighth piston 625 closes the thirteenth water hole 614 and the fourteenth water hole 615 but opens the fifteenth water hole 616 and the sixteenth water hole 617; the ninth piston 626 opens the seventeenth water hole 618 and the eighteenth water hole 619; the solenoid valve 603 is closed; and the second piston 504 in the second cylinder 501 is located in the middle position within the second cylinder 501. In this invention, the atomizing nozzle 640 connected to the third water pipe 639 on the crossbar 106 is in a ready-to-spray state.

[0072] When it is necessary to atomize and spray the air through the atomizing nozzle 640 on the top crossbar 106 of the lamp post 101 to remove dust, the control solenoid valve 603 is opened. Water with a certain water pressure in the water supply pipe 113, under its own pressure, flows through the first branch pipe 633, the fifteenth water hole 616, the annular space between the eighth piston 625 and the ninth piston 626, the sixteenth water hole 617, the fifth water pipe 644, and the second water hole 203 to the water tank 201 to fill the water tank 201. This causes the water level in the water tank 201 to rise rapidly and become full. After the water tank 201 is full, under the action of water pressure, the water flows through the first water hole 202, the sixth water pipe 645, the eighteenth water hole 619, the annular space between the tenth piston 627 and the ninth piston 626, the seventeenth water hole 618, and the third water pipe 639 to the atomizing nozzle 640 on the crossbar 106 for atomized spraying, thereby effectively reducing dust in the air and achieving the effect of purifying the air.

[0073] While atomizing and spraying the air to remove dust, the water supply pipe 113 can replenish the water tank 201, preventing water loss in the water tank 201 during long-term repeated use and ensuring that the water level regulating component 400 can effectively regulate the water volume in the water tank 201.

[0074] When the spraying needs to be stopped, simply close the solenoid valve 603.

[0075] When it is necessary to increase the water level in water tank 201, such as Figure 18 As shown in (b), the electric push rod 630 is activated, which drives the fourth piston 621, fifth piston 622, sixth piston 623, seventh piston 624, eighth piston 625, ninth piston 626 and tenth piston 627 on the fourth push-pull rod 620 to move downward synchronously from the spraying position by one amplitude. This causes the ninth water hole 610, tenth water hole 611, thirteenth water hole 614 and fourteenth water hole 615 on the cylindrical shell 605 to open. At the same time, the solenoid valve 603 is opened, and the pressurized water in the water supply pipe 113 flows through the first water pipe 601, the second branch pipe 634, the thirteenth water hole 614 and the seventh piston under the action of water pressure. The annular space between piston 624 and piston 625, the fourteenth water hole 615, the sixth branch pipe 642, the fourth water pipe 641 and the sixth water hole 503 reach the space below piston 504 in the second cylinder 501 and push piston 504 upward. The water in the space above piston 504 in the second cylinder 501 is discharged to the sewer through the fifth water hole 502, the seventh water pipe 646, the eighth branch pipe 647, the tenth water hole 611, the annular space between piston 622 and piston 623, the ninth water hole 610, the fifth branch pipe 638, the second water pipe 636 and the drain pipe 112.

[0076] The second piston 504 drives the second push-pull rod 505 and the third push-pull rod 508 to move upward synchronously. The second push-pull rod 505 drives the first piston 409 to move upward in the first cylinder 401 through the connecting rod 507 and the first push-pull rod 410. The first piston 409 pushes the water in the first cylinder 401 upward into the water tank 201 through the fourth water hole 402, the first connecting pipe 408 and the third water hole 204. The water level in the water tank 201 rises and the water volume increases. When the water volume in the water tank 201 increases to the required value, the solenoid valve 603 is closed.

[0077] The amount of water in the water tank 201 is proportional to the vibration intensity of the lamp post 101. The vibration intensity of the lamp post 101 is sensed by the vibration sensor 110 at the top of the lamp post 101 and the opening time of the solenoid valve 603 is controlled by the control system.

[0078] When it is necessary to increase the water level in water tank 201, such as Figure 18 As shown in (a), the electric actuator 630 drives the fourth piston 621, fifth piston 622, sixth piston 623, seventh piston 624, eighth piston 625, ninth piston 626, and tenth piston 627 on the fourth push-pull rod 620 to move synchronously downwards from the spraying position by one amplitude. This causes the seventh water hole 608, eighth water hole 609, eleventh water hole 612, and twelfth water hole 613 on the cylindrical shell 605 to open. At the same time, the solenoid valve 603 is opened, and the pressurized water in the water supply pipe 113 flows through the first water pipe 601, the third branch pipe 635, the seventh water hole 608, and the fourth piston 627 under water pressure. The annular space between piston 21 and fifth piston 622, eighth water hole 609, ninth branch pipe 648, seventh water pipe 646 and fifth water hole 502 reach the space above second piston 504 in second cylinder 501 and push second piston 504 downward. Water in the space below second piston 504 in second cylinder 501 is discharged to the sewer through sixth water hole 503, fourth water pipe 641, seventh branch pipe 643, twelfth water hole 613, annular space between sixth piston 623 and seventh piston 624, eleventh water hole 612, fourth branch pipe 637, second water pipe 636 and drain pipe 112.

[0079] The second piston 504 drives the second push-pull rod 505 and the third push-pull rod 508 to move downwards synchronously. The second push-pull rod 505 drives the first piston 409 to move downwards in the first cylinder 401 through the connecting rod 507 and the first push-pull rod 410. The first piston 409 draws water from the water tank 201 into the first cylinder 401 through the third water hole 204, the first connecting pipe 408 and the fourth water hole 402. The water level in the water tank 201 drops and the water volume decreases. When the water volume in the water tank 201 decreases to the required value, the solenoid valve 603 is closed.

[0080] The amount of water in the water tank 201 is proportional to the vibration intensity of the lamp post 101. The vibration intensity of the lamp post 101 is sensed by the vibration sensor 110 at the top of the lamp post 101 and the opening time of the solenoid valve 603 is controlled by the control system.

[0081] When the lamp post 101 vibrates, the lamp post 101 causes the water tank 201 to shake through the first spring 210. The water in the water tank 201 shakes, and the first spring 210 increases the damping force of the lamp post 101 when it vibrates, thereby effectively absorbing and buffering the vibration of the lamp post 101. The iron block 211 in the water tank 201 shakes along with the water in the water tank 201 when the lamp post 101 vibrates. The shaking of the iron block 211 can effectively increase the damping effect of the main vibration damping component 200 on the vibration of the lamp post 101.

[0082] During the vibration of the lamp post 101, the first cylinder 401 also vibrates under the action of the fourth spring 407. Since the first cylinder 401 is also filled with water, the movement of the water in the cylinder also assists the main vibration damping assembly 200 in absorbing and buffering the vibration of the lamp post 101 to a certain extent. In addition, since the connecting rod 507 is very long, when the first cylinder 401 in the water level adjustment assembly 400 swings due to the vibration of the lamp post 101, the connecting rod 507 drives the first piston 409 through the first push-pull rod 410 to move the first cylinder 401 very little, which basically affects the water volume in the water tank 201 in the main vibration damping assembly 200. This ensures that the water volume in the water tank 201 in the main vibration damping assembly 200 remains constant and has an effective absorption and buffering effect on the corresponding vibration of the lamp post 101, ensuring that the lamp 105 installed at the top of the lamp post will not fall off due to the violent vibration of the lamp post.

[0083] The secondary vibration damping component 300 in this invention is a mechanical vibration damping component. When the lamp post 101 vibrates, the damping shell of the secondary vibration damping component 300 will vibrate up and down and swing. The steel ball 304 inside the damping shell will move to cancel the vibration of the lamp post 101 while the damping shell swings and vibrates, thereby generating a corresponding degree of damping force. This assists the main vibration damping component 200 in effectively absorbing and buffering the vibration of the lamp post 101, ensuring that the lamp 105 installed at the top of the lamp post will not fall off due to the violent vibration of the lamp post.
