Description

Technical Field

[0001] The present invention relates to a vibration damping bracket, belonging to the technical field of anti-vibration brackets, and particularly to a bracket with improved anti-vibration ability. Background Art

[0002] A fire control cabinet refers to equipment used to control and monitor the fire protection system in a building. It usually includes a fire alarm controller, a fire pump controller, a sprinkler fire extinguishing system controller, a smoke detector, a manual fire alarm button, etc. The main function of the fire control cabinet is to centrally manage and control the fire protection system to ensure timely response and effective fire extinguishing measures in case of a fire, protecting the safety of people and property.

[0003] In the prior art, there are certain deficiencies in the bracket design of the fire control cabinet, especially in terms of anti-vibration ability. Many traditional fire control cabinet brackets do not fully consider the impact of external vibration or wind on the equipment. As a result, when subjected to strong wind or vibration, the bracket cannot effectively resist these external forces, leading to damage to the electrical components inside the equipment. Especially in outdoor environments, the fire control cabinet is often exposed to areas with strong winds. The wind or other vibration sources are transmitted to the cabinet body through the bracket, causing the cabinet body to shake or tilt, and even possibly causing the fire control cabinet to topple. At this time, the electronic components in the cabinet may fail due to vibration or impact, thereby affecting the normal operation of the entire fire protection system. In severe cases, it may lead to failure to respond in a timely manner during a fire and inability to effectively implement fire extinguishing measures. Summary of the Invention

[0021] As Figures 1 to 3 , Figure 10 shown, the first embodiment of the present invention provides a vibration damping bracket, comprising: a bracket 1, an installation space for carrying a fire cabinet is formed inside the bracket 1; wherein, the side plate 101 of the bracket 1 has N ventilation holes 1011; an air flow guiding assembly 2, installed on the side plate 101; wherein, the air flow guiding assembly 2 has an open state and a closed state; in the open state, the air flow guiding assembly 2 does not block or blocks M1 ventilation holes 1011 of the side plate 101; in the closed state, the air flow guiding assembly 2 blocks M2 ventilation holes 1011 of the side plate 101 and is configured to guide air flow in a first direction; moreover, M1 < M2 < N; moreover, the first direction is the direction from the top plate 102 of the bracket 1 to the bottom plate 103 of the bracket 1; moreover, the air flow guiding assembly 2 is controlled by a force F1 and a force F2 and switches between the open state and the closed state; wherein, the force F2 is the wind force received by the air flow guiding assembly 2, and the force F1 is the elastic force for maintaining the air flow guiding assembly 2 in the open state.

[0022] In this embodiment, the bracket 1 serves as the support structure of the entire device, providing a stable platform for carrying the fire cabinet to ensure that the fire cabinet is not interfered by the outside world during operation. The installation space inside it is specifically used for placing the fire cabinet to ensure that the cabinet body can be stably installed in various external environments. The ventilation holes are designed to improve the ventilation and heat dissipation effect inside the fire cabinet.

[0023] The number of the N ventilation holes 1011 enables air to freely circulate inside the bracket 1, effectively reducing the temperature inside the device and preventing overheating of electrical components. The arrangement of multiple ventilation holes 1011 increases the area of air circulation and improves the heat dissipation efficiency. This is crucial for the electrical components inside the fire cabinet, which can extend the service life of electronic devices and ensure the normal operation of the devices.

[0024] The function of the air flow guiding component 2 is to control and guide the air flow direction, ensuring smooth air flow inside the bracket 1 and maintaining an appropriate heat dissipation effect. The installation position of the air flow guiding component 2 on the side plate 101 can directly affect the air flow effect of the ventilation hole 1011.

[0025] Specifically, in the open state, as Figure 2 shown, the main purpose of the air flow guiding component 2 is to ensure the heat dissipation effect inside the fire cabinet. At this time, the air flow guiding component 2 will not significantly block or only partially block the ventilation hole 1011 on the side plate 101 of the bracket 1, so that the ventilation hole 1011 of the side plate 101 can be kept unobstructed, ensuring smooth air flow. The air freely circulates through the ventilation hole 1011, effectively dissipating the heat inside the fire cabinet, preventing the temperature inside the fire control cabinet from being too high, and ensuring the stable operation of the electrical components.

[0026] As Figure 10 shown, in the closed state, it automatically transitions when the wind force is large, reducing the wind force arm and enhancing stability: When the external wind force is large, the air flow guiding component 2 will automatically transition to the closed state. In this state, the air flow guiding component 2 adjusts so that the wind force is guided to the bottom of the fire control cabinet. This structure can effectively concentrate the acting force of the wind force on the bottom of the fire cabinet and, by changing the acting force arm of the wind force, significantly reduce the influence of the wind force on the inclination of the fire control cabinet.

[0027] By guiding the wind force to the bottom of the fire control cabinet and reducing the acting force arm, the air flow guiding component 2 effectively improves the wind resistance stability of the fire control cabinet. Thus, when the wind force is large, it can reduce the disturbance of the external force on the bracket 1, thereby avoiding damage to the cabinet body due to inclination or abnormal operation.

[0028] Although the number of blocked ventilation holes 1011 increases in the closed state, the air flow guiding component 2 still maintains a certain heat dissipation capacity. Through appropriate air flow guidance, it ensures that the temperature inside the fire cabinet will not be too high due to the guidance of the external wind force, thus maintaining the temperature stability of the equipment.

[0029] The air flow guiding component 2 in the present invention has two working states: the open state and the closed state. In the open state, the air flow guiding component 2 maximally guarantees the heat dissipation of the fire cabinet, ensuring that the equipment can dissipate heat normally during operation and preventing overheating. In the case of large wind force, the air flow guiding component 2 will automatically transition to the closed state, changing the guiding direction of the wind force, guiding the wind force to the bottom of the fire cabinet, reducing the acting force arm of the wind force, improving the stability of the equipment, and reducing the influence of the wind force on the inclination and vibration of the cabinet body.

[0030] Among them, the switching between the above two states of the air flow guiding component 2 is determined by the acting force F1 and the acting force F2.

[0031] When the wind force exceeds a certain threshold and the acting force F2 is greater than the acting force F1, the air flow guiding component 2 will automatically switch to the closed state, so that the action of the wind force can be effectively guided to the bottom of the fire control cabinet, reducing the interference to the bracket 1 and the cabinet body.

[0032] When the wind force is small, the air flow guiding component 2 remains in the open state and is maintained by the elastic force F1. This can ensure that the heat dissipation inside the fire control cabinet continues under normal wind speeds. The air flow guiding component 2 can adaptively switch the working state under different wind force conditions through the perception and feedback of the acting force F1 (elastic force) and the acting force F2 (wind force). This adaptive switching mechanism enables the damping bracket to maintain high stability in different environments and improves the anti-vibration ability of the fire control cabinet under extreme wind forces.

[0033] As Figures 2 to 5 shown, the second embodiment of the present invention provides a damping bracket. On the basis of the above embodiment, the air flow guiding component 2 includes a plurality of guiding parts, and each guiding part includes: a mounting frame 201 and a guiding fan blade 202; Among them, the guiding fan blade 202 is rotationally connected to the mounting frame 201 through a torsion member; And, the torsion member is configured to provide an acting force F1 to maintain the guiding fan blade 202 in the open state; Among them, the mounting frame 201 located close to the top plate 102 of the bracket 1 is fixedly connected to the side plate 101; And, the remaining mounting frames 201 are sequentially slidably connected to the side plate 101 along the height direction of the side plate 101; And, adjacent mounting frames 201 are connected by an elastic member 203.

[0034] In this embodiment, the air flow guiding component 2 is composed of a plurality of guiding parts, and each guiding part includes a mounting frame 201 and a guiding fan blade 202. Through the cooperative action of the plurality of guiding parts, the overall air flow regulation ability of the air flow guiding component 2 is enhanced, and it can more flexibly cope with the air flow guiding tasks under different wind speed conditions. The structure of each guiding part is independent of other guiding parts, ensuring better adaptability and adjustment ability in the overall system.

[0035] Among them, the guiding vanes 202 of each guiding part are rotationally connected to the mounting bracket 201 through a torsion member (which can be a torsion spring). The acting force F1 of the torsion member is used to maintain the guiding vane 202 in an open state. With this structure, the torsion member provides the necessary elastic acting force for the guiding vane 202, enabling the vane to maintain a predetermined angle, preventing it from closing on its own, and ensuring the air flow guiding function in the open state. Among them, the predetermined angle is that the guiding vane 202 inclines at a certain angle towards the bottom plate 103 of the bracket 1.

[0036] Among them, the mounting bracket 201 close to the top plate 102 of the bracket 1 is fixedly connected to the side plate 101, while the remaining mounting brackets 201 are sequentially slidably connected along the height direction of the side plate 101. Through this sliding connection, the air flow guiding assembly 2 can adjust its position when needed. The function of the elastic member 203 is to provide a certain elastic support for the mounting bracket 201, ensuring that the air flow guiding assembly 2 can respond flexibly and adjust its state when the wind force changes.

[0037] In a specific embodiment, the side plate 101 is provided with a mounting groove 1012, and both ends of the mounting bracket 201 are slidably connected within the mounting groove 1012.

[0038] In a specific embodiment, the mounting bracket 201 is provided with a rotation hole 2011, and both ends of the guiding vane 202 are rotationally connected within the rotation hole 2011 and connected to the torsion member, that is, the torsion spring.

[0039] In a specific embodiment, the elastic member 203 is a spring, and the spring is used to apply an acting force that makes adjacent mounting brackets 201 approach each other.

[0040] As Figures 5 to 6 shown, the third embodiment of the present invention provides a damping bracket, and on the basis of the above embodiments, the guiding vane 202 includes: An elastic engaging member 2021, located at the connection position between the guiding vane 202 and the mounting bracket 201; And, the elastic engaging member 2021 has an elastic acting force F3 to engage with the mounting bracket 201; Among them, the elastic acting force F3 is greater than the acting force F1.

[0041] In this embodiment, the elastic engaging member 2021 is located at the connection position between the guiding fan blade 202 and the mounting bracket 201, and has an elastic acting force F3, so that the guiding fan blade 202 can be firmly engaged on the mounting bracket 201, preventing the guiding fan blade 202 from loosening or falling off under low wind force or external force, and maintaining the stability of the guiding fan blade 202 in the open state. The elastic acting force F3 is greater than the acting force F1 provided by the torsion member that maintains the guiding fan blade 202 in the open state, so as to ensure that under normal circumstances, the elastic engaging member 2021 can stably fix the guiding fan blade 202 without loosening or deforming under the influence of small external forces.

[0042] When the wind force reaches a certain intensity and the acting force F2 is greater than the elastic acting force F3, the elastic engaging member 2021 will lose its engaging effect. At this time, the guiding fan blade 202 will rotate under the action of the wind force and gradually transition to the closed state. In this process, the rotation of the guiding fan blade 202 is driven by the wind force, and the failure of the elastic engaging member 2021 enables the guiding fan blade 202 to rotate freely, ensuring that the air flow guiding assembly 2 can automatically switch its working state according to changes in the external environment. At this time, the path of the air flow will be guided to the bottom of the fire control cabinet, effectively reducing the force arm of the wind force, thereby improving the stability of the bracket 1, preventing the wind force from generating too large a tilting moment on the fire control cabinet, and ensuring its stability and anti-vibration ability.

[0043] Thus, through the elastic engaging member 2021 between the guiding fan blade 202 and the mounting bracket 201, it is ensured that the air flow guiding assembly 2 can work stably when the wind force is small, and due to the characteristics of the elastic engaging member 2021, when the wind force is large, the air flow guiding assembly 2 can automatically transition to the closed state, thereby more effectively guiding the air flow and reducing the influence of the wind force on the bracket 1. The wind resistance and stability of the bracket 1 are effectively improved, ensuring the normal use of the fire control cabinet under various extreme weather conditions, and at the same time protecting the internal electronic components of the equipment from the influence of wind force or vibration.

[0044] In a specific embodiment, the elastic engaging member 2021 is a clamping block, which is connected with a spring and thus has an elastic acting force F3. Among them, a clamping groove is provided inside the rotating hole 2011 of the mounting bracket 201, and the clamping block and the clamping groove form an engagement. When the wind force is large enough, the clamping block disengages from the clamping groove, and the guiding fan blade 202 can rotate in the Figure 3 clockwise direction as shown to Figure 10 the closed state shown.

[0045] As Figures 3 to 6 shown, the fourth embodiment of the present invention provides a damping bracket, and on the basis of the above embodiment, the guiding fan blade 202 includes: Contact arms 2022, located at both ends of the guiding fan blade 202; The abutting support arm 2022 is configured to abut against the lower mounting bracket 201 when the guiding fan blade 202 transitions from the open state to the closed state, and push the lower mounting bracket 201 to descend along the height direction of the side plate 101; The lengths of the plurality of abutting support arms 2022 increase sequentially along the first direction.

[0046] In this embodiment, abutting support arms 2022 are provided on both sides of the guiding fan blade 202. The abutting support arms 2022 ensure that when the guiding fan blade 202 transitions from the open state to the closed state, it can effectively contact the lower mounting bracket 201 and push the lower mounting bracket 201 to move downward along the height direction of the side plate 101. As the guiding fan blade 202 rotates, the abutting support arms 2022 push the lower mounting bracket 201 to descend through contact with the lower mounting bracket 201. In addition, the lengths of the plurality of abutting support arms 2022 increase sequentially along the first direction, resulting in different descending heights of each mounting bracket 201. This height difference directly leads to a gradual increase in the spacing between the mounting brackets 201 along the first direction (i.e., the direction from the top plate 102 to the bottom plate 103 of the bracket 1), thereby creating multiple ventilation areas with different areas. Specifically, along the first direction, the area of the air flow channel gradually increases (i.e., the area of the upper air flow channel is small, and the area of the lower air flow channel is large. The air flow channel refers to the collection of a plurality of ventilation holes 1011). Thus, in the vertical direction, the upper region of the fire cabinet inside the bracket 1 is subjected to less wind force (because the air volume is small), and the lower region is subjected to greater wind force (because the air volume is large). That is to say, the wind force is more concentrated and acts on the bottom of the fire cabinet in large quantities, thereby reducing the acting arm of the wind force on the fire cabinet and enhancing the stability of the fire cabinet. And below, the wind force will flow through multiple ventilation areas of different sizes, further dispersing and slowing down the wind speed, avoiding the direct impact of the wind force on the fire control cabinet, and thus effectively improving the wind resistance and stability of the fire cabinet.

[0047] As Figures 4 to 5 shown, the fifth embodiment of the present invention provides a damping bracket. On the basis of the above embodiment, the guiding fan blade 202 includes: A lateral guiding member 2023, located on the windward side of the guiding fan blade 202; Wherein, the lateral guiding member 2023 has a guiding surface inclined towards both sides of the side plate 101.

[0048] In this embodiment, the guiding surface of the lateral guiding member 2023 is inclined towards both sides of the bracket 1, which can effectively guide the airflow to disperse towards both sides of the side plate 101. Under the action of wind force, the structure with the guiding surface inclined towards both sides of the side plate 101 enables the air flow to be dispersed and guided to the ventilation holes 1011 on both sides of the side plate 101 when passing through the guiding fan blades 202, rather than concentrating on a single ventilation area. In this way, by optimizing the air flow path, the concentrated impact force of the air flow is reduced, and at the same time, the ventilation efficiency is increased. With this structure, the air flow is effectively guided and dispersed before entering the interior of the bracket 1, further reducing the impact of wind force on the fire control cabinet.

[0049] As Figures 7 to 9 shown, the sixth embodiment of the present invention provides a shock-absorbing bracket, and on the basis of the above embodiment, it includes: The energy storage component 3 is arranged below the bracket 1; wherein, the energy storage component 3 is controlled by wind force to form a gyroscopic rotational motion.

[0050] In this embodiment, the function of the energy storage component 3 is to generate a gyroscopic rotational motion under the action of wind force. The aim is to improve the stability of the bracket 1 under the action of wind force, especially to enhance the wind resistance and vibration absorption capabilities.

[0051] Specifically, when wind force acts on the energy storage component 3, the rotating element inside the energy storage component 3 starts to rotate and gradually accumulates kinetic energy to form a rotational motion similar to the gyroscopic effect. Due to the angular momentum conservation characteristic of the gyroscopic effect, the rotation of the energy storage component 3 can effectively maintain the stability of the system, resist external wind force and vibration impacts, so that when the bracket 1 encounters wind force or vibration, it can be better stabilized and reduce unnecessary swaying or vibration. Through this structure, the overall stability of the bracket 1 is improved, preventing excessive impacts on the bracket 1 caused by external wind force or vibration and ensuring the safety of the fire control cabinet.

[0052] In addition, the air flow guiding component 2 can also guide the wind force to the lower part of the bracket 1 and directly act on the energy storage component 3 to further drive the energy storage component 3 to generate a gyroscopic rotational motion, thereby enhancing the stability and wind vibration resistance of the bracket 1.

[0053] The seventh embodiment of the present invention provides a shock-absorbing bracket, and on the basis of the above embodiment, the energy storage component 3 includes: The bearing plate 301; The static shaft 302 is arranged between the bearing plate 301 and the bottom plate 103 of the bracket 1; The moving ring 303 is rotatably connected to the static shaft 302; The rotating fan blades 304 are slidably inserted along the circumferential wall surface of the moving ring 303 into the moving ring 303; The rotating blades 304 are configured to be controlled by wind force to drive the dynamic ring 303 to rotate; Furthermore, the length of each rotating blade 304 extending from the moving ring 303 increases or decreases in sequence.

[0054] In this embodiment, the bearing plate 301 is located at the bottom of the bracket 1, bearing the overall load of the bracket 1 and providing support for the components above it. The static shaft 302 is arranged between the bearing plate 301 and the bottom plate 103 of the bracket 1, serving as the rotation center of the entire energy storage component 3, ensuring the stability of the rotating parts. The dynamic ring 303 is rotatably connected to the static shaft 302, and can achieve rotational motion under the action of wind. The rotation of the dynamic ring 303 is driven by the rotating blades 304 arranged thereon, and the rotating blades 304 are inserted into the dynamic ring 303 by sliding along the circumferential wall of the dynamic ring 303, and generate rotational motion under the drive of wind. The extended length of each rotating blade 304 increases or decreases in sequence to adaptively adjust the working state of the energy storage component 3 according to the intensity of the wind.

[0055] Since the extension length of the rotating blade 304 gradually changes in the circumferential direction of the dynamic ring 303, in a top-down state, the end connection line of the rotating blade 304 presents a spiral shape, so that under different wind directions, the wind-receiving surface and the force of each blade will be different. The wind can act on the rotating blade 304 in multiple directions, prompting it to rotate. When the wind is strong, the wind in all directions can drive the rotating blade 304 to rotate and generate a rotational motion through the dynamic ring 303. It is thus possible to adapt to the change of the wind force and convert the rotational motion into effective angular momentum, thereby improving the wind resistance and stability of the bracket 1. In other words, through the change in the extension length and spiral distribution of the rotating blade 304, the energy storage component 3 can continue to rotate under the action of wind in multiple directions, thereby enhancing the overall stability of the bracket 1, especially in a strong wind and vibration environment, it can effectively reduce the impact of external factors on the fire control cabinet and ensure its safe operation.

[0056] In a specific embodiment, an annular groove is formed on the circumferential wall surface of the static shaft 302, and the dynamic ring 303 is rotatably connected in the annular groove.

[0057] In a specific embodiment, a plurality of equally spaced insertion grooves are formed on the circumferential wall surface of the dynamic ring 303, and the plate-shaped rotating blades 304 are slidably inserted into the insertion grooves.

[0058] like Figures 7 to 9 As shown, the eighth embodiment of the present invention provides a vibration-damping bracket, and on the basis of the above embodiment, the energy storage component 3 includes: A first guide portion is disposed between the rotating blade 304 and the moving ring 303; Among them, the first guiding portion is configured to apply a force to the rotating fan blade 304 to move it towards the center of the moving ring 303.

[0059] The second guiding portion is disposed between the rotating fan blade 304 and the stationary shaft 302; Among them, the second guiding portion is configured to regulate the length of the rotating fan blade 304 extending out of the moving ring 303 when the rotating fan blade 304 rotates.

[0060] In this embodiment, the extending lengths of the rotating fan blades 304 are intentionally limited to be different because, through these different extending lengths, the rotating fan blades 304 can generate different torques under the action of wind force, thereby better driving the rotation of the moving ring 303 to form a gyroscopic effect. The key to this structure lies in that by adjusting the extending length of the rotating fan blade 304, its windward area and the generated rotating torque can be controlled. Specifically, as the extending length of the rotating fan blade 304 increases or decreases, the distribution of the wind force acting on the rotating fan blade 304 can be effectively changed, thereby affecting the rotation speed and stability of the moving ring 303. This is to ensure that under different wind force conditions, the rotating fan blade 304 can efficiently drive the moving ring 303 to form a gyroscopic effect and enhance the anti-vibration performance.

[0061] The first guiding portion and the second guiding portion cooperate to regulate the extending length of the rotating fan blade 304. The first guiding portion is mainly responsible for applying a force towards the center of the moving ring 303 (for example, in the form of magnetic attraction or spring pulling), and the second guiding portion plays a role of adjustment and guidance when the rotating fan blade 304 rotates, and controls the influence of the wind force on the rotating fan blade 304 by changing the extending length of the rotating fan blade 304. Specifically, the first guiding portion and the second guiding portion act together to ensure that the extending length of the rotating fan blade 304 can be dynamically adjusted with the change of the wind force, so as to generate the required rotating torque and drive the moving ring 303 to form a gyroscopic effect.

[0062] In a specific embodiment, the second guiding portion includes: The guiding block 401 is disposed on the rotating fan blade 304; The guiding groove 402 is formed on the stationary shaft 302; And, the guiding block 401 and the guiding groove 402 are slidably connected.

[0063] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0064] The above embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
