Description

Technical Field

[0001] This invention relates to the technical field of brackets, specifically a vibration protection bracket. Background Technology

[0002] Scaffolding, also known as support structure, was originally a term in the construction industry, specifically referring to temporary support structures erected during the construction of buildings, which are removed once the building is completed. However, the meaning of "support" has now expanded to include things like the support poles for carports, camera tripods, and cardiac stents used in the medical field.

[0003] Chinese invention patent CN113775893A discloses a multi-stage lifting device with a top rod and its working method. The top rod in the device can be raised and lowered, thereby supporting the construction fixed surface such as the ceiling and enhancing the stability of the multi-stage lifting device itself. Due to the presence of the top rod, when the top rod is firmly supported on the fixed surface, the multi-stage lifting device can provide a stable vertical reference. Even if the working head is at a high construction height, the construction accuracy can be guaranteed by the multi-stage lifting device of this invention. However, it does not have a shockproof structure and is easily damaged in disasters such as earthquakes.

[0004] Chinese invention patent CN121828399A discloses a shock-absorbing bracket that uses a plastic hinge to shape and dissipate energy, thereby consuming the input seismic energy. At the same time, the formation of the plastic hinge can reduce the stiffness of the shock-absorbing bracket, lower the fundamental frequency of the overall structure, and make it deviate from the characteristic frequency of the building, thereby achieving frequency decoupling, avoiding resonance amplification effect, and reducing seismic response. However, its height cannot be adjusted, making it difficult to use in different environments. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a vibration-protected bracket that uses a hydraulically controlled telescopic rod to adjust the bracket's height. Magnetorheological fluid is used as the hydraulic oil, allowing for convenient height adjustment. Furthermore, in the event of a destructive event, the telescopic rod is reinforced by energizing the magnetorheological fluid, preventing significant damage to the bracket.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vibration protection bracket includes a mounting frame with multiple support rods hinged to its bottom. The bottom of each support rod is connected to a telescopic rod. An assembly chamber is located within the foundation beneath the mounting frame, and a liquid storage tank is located on top of the assembly chamber. The liquid storage tank is connected to the interior of the telescopic rod via an infusion pipe. A vibration triggering device is located at the bottom of the telescopic rod and is connected to the assembly chamber via a connecting pipe. The liquid storage tank contains hydraulic oil, specifically a magnetorheological fluid. A trigger sensor is located inside the assembly chamber and is electrically connected to a battery inside the liquid storage tank. The vibration triggering device includes a protective shell. The bottom of the inner cavity of the protective shell is fixed to the bottom of a first spring device, and the top of the first spring device is fixed to a connecting plate. Multiple connecting rods are evenly spaced on the outer periphery of the connecting plate, and the ends of the connecting rods opposite to the connecting plate are fixed to the inner wall of the protective shell. A needle is fixed to the top of the connecting plate, and a diaphragm matching the needle is located at the bottom of the telescopic rod. In a normal state, the first spring device is in a retracted state.

[0008] Furthermore, the trigger sensor is located in the middle of the assembly chamber, and multiple channels are opened inside the assembly chamber. These channels are used to connect the connecting pipe to the trigger switch of the trigger sensor.

[0009] Furthermore, a balancing device is provided at the center of the bottom of the mounting bracket.

[0010] Furthermore, the balancing device includes a housing, the top center of the inner wall of the housing is fixed to the top of the elastic suspension rope, the bottom of the elastic suspension rope is fixed to the mass block, and the interior of the housing is filled with a solution, the liquid level of which is higher than the top of the mass block.

[0011] Furthermore, the weight of the mass block is equal to the buoyancy of the solution.

[0012] Furthermore, the solution is a high-viscosity liquid.

[0013] Furthermore, a limiting chamber is provided on the outer periphery of the mass block, and a second spring device is fixed between the outer wall of the limiting chamber and the inner wall of the shell.

[0014] Furthermore, a photovoltaic panel is installed inside the mounting frame, and a battery compartment is installed at the bottom of the assembly compartment, with the photovoltaic panel electrically connected to the battery compartment.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention uses a hydraulically controlled telescopic rod to adjust the position of the mounting bracket, and uses magnetorheological fluid as the hydraulic oil, which allows the height of the bracket to be easily adjusted. In the event of a destructive event, the telescopic rod is reinforced by energizing the magnetorheological fluid to prevent the bracket from being damaged.

[0017] 2. When using this invention, the hydraulic oil in the storage tank is exchanged with the inside of the telescopic rod through the infusion pipe via a water pump or other device inside the storage tank. The more hydraulic oil is input into the telescopic rod, the higher the telescopic rod becomes, and the higher one end of the mounting bracket becomes. In this way, the mounting bracket can be adjusted to the set height and angle as needed.

[0018] 3. When disasters such as earthquakes and foundation settlement occur, the entire invention will vibrate. Due to the thin diameter of the connecting rod, it is prone to breakage during an earthquake. After breakage, the connecting plate and the first spring device lose the restraint of the connecting rod. The first spring device returns from the state of force contraction to the normal state, thereby raising the position of the piercing needle, allowing the piercing needle to pierce the membrane. The hydraulic oil inside the telescopic rod flows into the protective shell and then enters the assembly chamber through the connecting pipe. When the hydraulic oil touches the switch of the trigger sensor, the trigger sensor sends an electrical signal to the small battery in the reservoir, causing the small battery in the reservoir to discharge to the hydraulic oil. This triggers the properties of the hydraulic oil when it is energized, making the hydraulic oil less prone to flow, thereby reinforcing the telescopic rod and other devices and reducing the damage caused by vibration to the entire device.

[0019] 4. This invention uses a balancing device to counterweight the system consisting of the mounting frame and support rods, thereby reducing the amplitude of the mounting frame's sway and further improving the stability of the mounting frame and support rods. A high-viscosity liquid is used to increase the resistance to the swaying of the mass block, thus enhancing the overall stability of the balancing device.

[0020] 5. The present invention uses a limiting chamber to limit the range of the swing of the mass block, and uses a second spring device to limit the position of the limiting chamber, so as to prevent the mass block or the limiting chamber from hitting the inner wall of the shell, and at the same time improve the overall stability of the balancing device.

[0034] Example 1:

[0035] The vibration protection bracket in this embodiment includes a mounting frame 1. Multiple support rods 2 are hinged to the bottom of the mounting frame 1, and the bottom of each support rod 2 is connected to a telescopic rod 3. An assembly chamber 5 is installed within the foundation 8 below the mounting frame 1. A liquid storage tank 4 is installed on the top of the assembly chamber 5, and the liquid storage tank 4 is connected to the interior of the telescopic rod 3 via an infusion pipe 41. A vibration triggering device 6 is installed at the bottom of the telescopic rod 3, and the vibration triggering device 6 is connected to the assembly chamber 5 via a connecting pipe 52. The liquid storage tank 4 contains hydraulic oil 42, which is a magnetorheological fluid. A trigger sensor 51 is installed inside the assembly chamber 5. The sensor 51 is electrically connected to the battery inside the liquid storage tank 4; the vibration triggering device 6 includes a protective shell 61, the bottom of the inner cavity of the protective shell 61 is fixed to the bottom of the first spring device 62, the top of the first spring device 62 is fixed to the connecting plate 63, and a plurality of connecting rods 64 are evenly fixed on the outer periphery of the connecting plate 63. The end of the connecting rod 64 opposite to the connecting plate 63 is fixed to the inner wall of the protective shell 61; a needle 65 is fixed on the top of the connecting plate 63, and a thin film 31 matching the needle 65 is provided at the bottom of the telescopic rod 3; in the normal state, the first spring device 62 is in the retracted state.

[0036] When using this invention, the hydraulic oil 42 inside the storage tank 4 is pumped by a device such as a water pump to exchange fluid with the telescopic rod 3 through the infusion pipe 41. The more hydraulic oil 42 is input into the telescopic rod 3, the higher the telescopic rod 3 becomes, and the higher one end of the mounting frame 1 becomes. In this way, the mounting frame 1 can be adjusted to a set height and angle as needed. Protective sleeves are provided around the support rod 2 and the telescopic rod 3 in the underground section. These protective sleeves prevent the foundation 8 from obstructing the telescopic rod 3 during its extension and retraction, ensuring that the telescopic rod 3 can extend and retract normally, and thus ensuring that the position of the mounting frame 1 can be adjusted as needed.

[0037] In its normal state, the connecting rod 64 is used to fix the position of the connecting plate 63 and the needle 65. When disasters such as earthquakes and foundation settlement occur, the entire invention will vibrate. Since the connecting rod 64 has a small diameter, it is prone to breakage during earthquakes. After breakage, the connecting plate 63 and the first spring device 62 lose the restraint of the connecting rod 64. The first spring device 62 returns from the state of force contraction to the normal state, thereby raising the position of the needle 65, so that the needle 65 pierces the membrane 31. The hydraulic oil 42 inside the telescopic rod 3 flows into the protective shell 61 and then enters the assembly chamber 5 through the connecting pipe 52. When the hydraulic oil 42 touches the switch of the trigger sensor 51, the trigger sensor 51 sends an electrical signal to the small battery in the reservoir 4, causing the small battery in the reservoir 4 to discharge to the hydraulic oil 42, thereby triggering the properties of the hydraulic oil 42 (i.e., magnetorheological fluid, the same below) when energized, making the hydraulic oil 42 less prone to flow, thereby reinforcing the telescopic rod 3 and other devices and reducing the damage caused by vibration to the entire device. The assembly compartment 5 is also equipped with a vibration sensor, which is electrically connected to a small battery in the reservoir 4. When the vibration sensor detects vibration, it can directly send an electrical signal to the small battery in the reservoir 4, causing the small battery to supply power to the hydraulic oil 42. The trigger sensor 51 and the vibration sensor form two different discharge paths, improving the stability of the small battery's discharge.

[0038] Furthermore, the trigger sensor 51 is located in the middle of the inner cavity of the assembly chamber 5. Multiple channels 53 are opened inside the assembly chamber 5. The channels 53 are used to connect the connecting pipe 52 and the trigger switch of the trigger sensor 51.

[0039] Hydraulic oil 42 entering the assembly chamber 5 is diverted through channel 53 so that the hydraulic oil 42 can accurately contact the switch of the trigger sensor 51.

[0040] Furthermore, a balancing device 7 is provided at the center of the bottom of the mounting bracket 1.

[0041] The mounting frame 1 and the support rod 2 are counterweighted by the balancing device 7 to reduce the amplitude of swaying of the mounting frame 1 and the support rod 2 when vibration occurs, thereby further improving the stability of the mounting frame 1 and the support rod 2.

[0042] Furthermore, the balancing device 7 includes a housing 71, the top center of the inner wall of the housing 71 is fixed to the top of the elastic suspension rope 72, the bottom of the elastic suspension rope 72 is fixed to the mass block 73, and the interior of the housing 71 is filled with a solution 74, the liquid level of the solution 74 being higher than the top of the mass block 73.

[0043] The elastic suspension rope 72 and the mass block 73 form a counterweight stabilization system inside the housing 71, and the solution 74 is used to increase the resistance of the mass block 73 when it swings. When the balancing device 7 swings, the mass block 73 swings synchronously but with a smaller amplitude.

[0044] Furthermore, the weight of mass block 73 is equal to the buoyancy of solution 74.

[0045] Using a specific solution 74, the weight of the mass block 73 is equal to the buoyancy of the solution 74. In this state, the deformation of the elastic suspension rope 72 caused by the mass block 73 is minimized, allowing the elastic suspension rope 72 to have a larger deformation range when the mass block 73 swings.

[0046] Furthermore, solution 74 is a high-viscosity liquid.

[0047] Using a high-viscosity liquid increases the resistance of the mass block 73 during its swing, thereby improving the overall stability of the balancing device 7.

[0048] Furthermore, a limiting chamber 75 is provided on the outer periphery of the mass block 73, and a second spring device 76 is fixed between the outer wall of the limiting chamber 75 and the inner wall of the shell 71.

[0049] The range of swing of the mass block 73 is limited by the limiting chamber 75, and the position of the limiting chamber 75 is limited by the second spring device 76, so as to prevent the mass block 73 or the limiting chamber 75 from hitting the inner wall of the housing 71, and at the same time improve the overall stability of the balancing device 7.

[0050] The usage method of this embodiment is as follows:

[0051] When using this invention, the hydraulic oil 42 inside the storage tank 4 is pumped by a device such as a water pump to exchange fluid with the telescopic rod 3 through the infusion pipe 41. The more hydraulic oil 42 is input into the telescopic rod 3, the higher the telescopic rod 3 becomes, and the higher one end of the mounting frame 1 becomes. In this way, the mounting frame 1 can be adjusted to a set height and angle as needed. Protective sleeves are provided around the support rod 2 and the telescopic rod 3 in the underground section. These protective sleeves prevent the foundation 8 from obstructing the telescopic rod 3 during its extension and retraction, ensuring that the telescopic rod 3 can extend and retract normally, and thus ensuring that the position of the mounting frame 1 can be adjusted as needed.

[0052] When disasters such as earthquakes and foundation settlement occur, the entire invention will vibrate. Since the connecting rod 64 has a small diameter, it is prone to breakage during an earthquake. After breakage, the connecting plate 63 and the first spring device 62 lose the restraint of the connecting rod 64. The first spring device 62 returns from the state of force contraction to the normal state, thereby raising the position of the piercing needle 65, so that the piercing needle 65 pierces the membrane 31. The hydraulic oil 42 inside the telescopic rod 3 flows into the protective shell 61 and then enters the assembly chamber 5 through the connecting pipe 52. When the hydraulic oil 42 touches the switch of the trigger sensor 51, the trigger sensor 51 sends an electrical signal to the small battery in the reservoir 4, causing the small battery in the reservoir 4 to discharge to the hydraulic oil 42, thereby triggering the properties of the hydraulic oil 42 (i.e., magnetorheological fluid, the same below) when energized, making the hydraulic oil 42 less prone to flow, thereby reinforcing the telescopic rod 3 and other devices and reducing the damage caused by vibration to the entire device. The assembly compartment 5 is also equipped with a vibration sensor, which is electrically connected to a small battery in the reservoir 4. When the vibration sensor detects vibration, it can directly send an electrical signal to the small battery in the reservoir 4, causing the small battery to supply power to the hydraulic oil 42. The trigger sensor 51 and the vibration sensor form two different discharge paths, improving the stability of the small battery's discharge.

[0053] Vibration also triggers the balancing device 7, which counterweights the system consisting of the mounting frame 1 and the support rod 2 to reduce the amplitude of swaying and further improve the stability of the mounting frame 1 and the support rod 2. The elastic suspension rope 72 and the mass block 73 form a counterweight stabilization system inside the housing 71. Solution 74 is used to increase the resistance of the mass block 73 during swaying. When the balancing device 7 oscillates, the mass block 73 oscillates synchronously but with a smaller amplitude. A specific solution 74 is used to make the weight of the mass block 73 equal to the buoyancy of the solution 74. In this state, the deformation of the elastic suspension rope 72 caused by the mass block 73 is minimized, allowing the elastic suspension rope 72 to have a larger deformation range when the mass block 73 oscillates. Using a high-viscosity liquid increases the resistance of the mass block 73 during swaying, thereby improving the overall stability of the balancing device 7. The range of swing of the mass block 73 is limited by the limiting chamber 75, and the position of the limiting chamber 75 is limited by the second spring device 76, so as to prevent the mass block 73 or the limiting chamber 75 from hitting the inner wall of the housing 71, and at the same time improve the overall stability of the balancing device 7.

[0054] Example 2:

[0055] Based on Example 1, Example 2 has a photovoltaic panel 10 installed in the mounting frame 1, a battery compartment 9 installed at the bottom of the assembly compartment 5, and the photovoltaic panel 10 is electrically connected to the battery compartment 9.

[0056] With the structure of Embodiment 2, this device can form a charging shed. The electrical energy converted by the photovoltaic panel 10 will be stored in the battery compartment 9 to charge the vehicle. A photosensitive sensor can also be installed on the surface of the photovoltaic panel 10 to track sunlight. When the sunlight detected by the photosensitive sensor is less than a set value, the photosensitive sensor controls the amount of solution in each telescopic rod 3 through the controller in the liquid storage tank 4, thereby adjusting the height of the different telescopic rods 3, and thus adjusting the mounting frame 1 to the angle with the strongest light intensity.

[0057] Furthermore, a solution layer can be set inside the liquid storage tank 4 to protect the battery in the battery compartment 9. The solution in the solution layer also uses magnetorheological fluid, but the solution layer is in a discharged state under normal conditions. At this time, the solution layer is difficult to flow, thereby improving the stability of the battery and avoiding damage to the battery due to vibration under normal conditions. When vibration occurs, the trigger sensor 51 (or vibration sensor) is activated to de-energize the solution layer, and the fluidity of the solution layer is enhanced, which can reduce the impact of vibration on the battery compartment 9.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
