Description

Technical Field

[0001] This invention relates to the field of cabinet technology, specifically to an indoor anti-tipping safety and earthquake-resistant cabinet. Background Technology

[0002] A control panel is a metal enclosure used for the centralized installation and protection of electrical equipment, widely used in power distribution, control, and data processing systems. Its compact design facilitates the integration of circuit breakers, disconnectors, measuring instruments, and other equipment, while providing fireproof, dustproof, and waterproof protection to ensure stable operation of equipment in a safe environment. Through standardized installation interfaces and centralized management functions, control panels significantly improve the operational efficiency and maintenance convenience of power systems, becoming an indispensable infrastructure in industries such as manufacturing, construction, and transportation.

[0003] Currently, when control panels are subjected to continuous, minor vibrations, the mounting brackets of internal electrical components are prone to displacement, causing additional stress on the connecting lines and potentially leading to loosening or breakage of the wiring. Specifically, this manifests as poor contact in components such as relays and contactors due to vibration, while wiring terminals are easily loosened, increasing contact resistance and potentially causing localized overheating or even electrical sparks, significantly increasing the risk of electrical fires. Furthermore, when subjected to strong vibrations such as earthquakes, control panels also pose a risk of tipping over, creating a serious safety hazard. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an indoor anti-tipping safety earthquake-resistant cabinet, which solves the problems that existing cabinets are prone to electrical component displacement, loose wiring and poor contact under continuous vibration, increasing the risk of fire, and also pose a risk of tipping over during strong earthquakes.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an indoor anti-tipping safety earthquake-resistant cabinet, comprising a cabinet body, characterized in that: a plurality of first shock-absorbing springs are symmetrically fixedly connected to the bottom of the cabinet body, the bottoms of the plurality of first shock-absorbing springs are jointly fixedly connected to a base, and two damping mechanisms are jointly installed between the base and the cabinet body; Both of the damping mechanisms include a linkage assembly, and two hydraulic dampers are installed between the linkage assembly and the base; The top of the base is symmetrically and fixedly connected to four columns on the outside of the cabinet body. A synchronous drive assembly located at the bottom and outside of the cabinet body is installed between the four columns. A screw lifting assembly located on the outside of the cabinet body is installed on both movable ends of the synchronous drive assembly. A synchronous transmission assembly located on the outside of the cabinet body is installed on both movable ends of the two screw lifting assemblies. A first side support rod and a second side support rod located on the outside of the cabinet body are fixedly connected to the two movable ends of the four synchronous transmission assemblies, respectively. All four columns are fixedly connected to the cabinet body by a second shock-absorbing spring; A vibration sensor is fixedly installed on one side of the top of the base.

[0006] Preferably, both of the connecting rod assemblies include a cross seat, which is fixedly installed at the bottom of the cabinet body. Two connecting rod bodies are symmetrically rotatably connected to one side of the outer surface of the cross seat. A connecting block is rotatably connected to the bottom of one side of the outer surface of each of the two connecting rod bodies, and the connecting block is fixedly connected to the movable end of the adjacent hydraulic damper.

[0007] Through the above technical solution, the multi-link structure design can evenly distribute the vibration energy of the cabinet to multiple hydraulic dampers, significantly improving the vibration reduction efficiency, while avoiding structural damage caused by excessive force at a single point.

[0008] Preferably, each of the four hydraulic dampers includes a cylinder, which is fixedly installed on the inner wall of one side of the base. A piston is slidably sealed inside the cylinder, and a slide rod is fixedly connected to one side of the outer surface of the piston. The slide rod passes through the cylinder and is slidably sealed to the cylinder. The slide rod is also fixedly connected to an adjacent connecting block.

[0009] Through the above technical solution, the hydraulic damper has a compact structure and good sealing performance, and can effectively convert mechanical vibration into damping force of hydraulic oil flow, thereby achieving smooth vibration reduction.

[0010] Preferably, the interior of the cylinder is filled with hydraulic oil, and two fine holes are symmetrically opened on one side of the outer surface of the piston, extending to the other side.

[0011] Through the above technical solutions, the fine-hole design can precisely control the flow speed of hydraulic oil, so that the damping force can be adaptively adjusted according to the vibration intensity, ensuring both daily shock absorption and the ability to cope with sudden strong shock impacts.

[0012] Preferably, the synchronous drive assembly includes two crossbars, which are fixedly connected to two adjacent columns. The tops of the two crossbars are rotatably connected to synchronous pulleys, and a synchronous belt is meshed between the two synchronous pulleys.

[0013] Through the above technical solution, the synchronous transmission mechanism ensures that the support rods on both sides unfold synchronously, avoiding cabinet tilting due to asynchrony and improving anti-tipping reliability.

[0014] Preferably, a motor is fixedly connected to the bottom of each crossbar, and the drive shaft of the motor passes through the crossbar and is fixedly connected to the adjacent synchronous pulley.

[0015] The above technical solution enables the motor drive to respond quickly, and when combined with the control system, it can achieve millisecond-level anti-tipping response, meeting the needs of earthquake emergency response.

[0016] Preferably, both screw lifting assemblies include a screw body, and the outer surface of the screw body is threaded with a movable seat, and the top of the movable seat is symmetrically and fixedly connected with two movable rods.

[0017] Through the above technical solution, the screw drive has a self-locking characteristic, which can ensure that the support rod maintains a stable position after it is deployed and will not retract due to vibration.

[0018] Preferably, all four synchronous transmission components include a housing, and the housing is slidably sleeved on the outer surface of the adjacent movable rod. The housing is provided with two racks inside, and the racks are fixedly connected to the movable rods. The outer surfaces of the two racks are meshed with gears. One end of the gear is fixedly connected to a connecting shaft, and the connecting shaft is fixedly connected to the adjacent first side support rod and the adjacent second side support rod.

[0019] Through the above technical solution, the gear and rack transmission mechanism efficiently converts vertical motion into rotational motion, ensuring that the support rod unfolds quickly and smoothly.

[0020] Preferably, the outer surfaces of both connecting shafts are fitted with mounting seats that limit rotation, and the mounting seats are fixedly connected to the housing and adjacent columns.

[0021] Through the above technical solution, the mounting base provides a stable rotation fulcrum for the support rod.

[0022] It has the following beneficial effects: This indoor anti-tipping safety seismic-resistant cabinet activates its synchronous drive component immediately upon detecting a strong earthquake signal via a vibration sensor. The screw-lifting mechanism rapidly deploys the side support rods, forming a rigid triangular support structure. This active anti-tipping system works in conjunction with the bottom shock absorption system, dissipating seismic energy through hydraulic dampers and providing anti-tipping moments through mechanical supports. This ensures the cabinet maintains a stable posture under strong earthquake conditions, effectively preventing equipment damage and personnel injury risks caused by cabinet tipping over, and significantly improving seismic safety performance.

[0023] This indoor anti-tipping safety earthquake-resistant cabinet effectively absorbs and buffers various types of vibration energy through the synergistic action of the bottom first shock-absorbing spring and the hydraulic damper. The hydraulic damper achieves adaptive damping adjustment through a piston orifice design, and together with multiple sets of shock-absorbing springs, forms a multi-stage vibration reduction system. This significantly reduces the vibration impact on the cabinet body and internal electrical components, preventing problems such as mounting bracket displacement and loose wiring terminals, ensuring the long-term stability and reliability of electrical connections, and fundamentally reducing poor contact and fire hazards caused by vibration.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figure 2 and Figure 3 As shown, this embodiment of the invention provides an indoor anti-tipping safety earthquake-resistant cabinet, including a cabinet body 3. Multiple first shock-absorbing springs 9 are symmetrically fixedly connected to the bottom of the cabinet body 3. The bottom of the multiple first shock-absorbing springs 9 is fixedly connected to a base 1. Two damping mechanisms are installed between the base 1 and the cabinet body 3. The structural design realizes the elastic connection between the cabinet and the ground, providing basic support for the subsequent shock absorption function.

[0028] Figure 3 and Figure 6As shown, both damping mechanisms include linkage assemblies. Two hydraulic dampers 71 are installed between the linkage assemblies and the base 1. Both linkage assemblies include a cross seat 73, which is fixedly installed at the bottom of the cabinet body 3. Two linkage bodies 72 are symmetrically rotatably connected to one side of the outer surface of the cross seat 73. A connecting block 74 is rotatably connected to the bottom of one side of the outer surface of each of the two linkage bodies 72. The connecting block 74 is fixedly connected to the movable end of the adjacent hydraulic damper 71. All four hydraulic dampers 71 include a cylinder 712, which is fixedly installed on the inner wall of one side of the base 1. The cylinder 712... An internally sealed sliding piston 714 is provided, and a slide rod 711 is fixedly connected to one side of the outer surface of the piston 714. The slide rod 711 passes through the cylinder 712 and is sealed and slidably connected to the cylinder 712. The slide rod 711 is also fixedly connected to the adjacent connecting block 74. The cylinder 712 is filled with hydraulic oil 715. Two fine holes 713 are symmetrically opened on one side of the outer surface of the piston 714, extending to the other side. This multi-link hydraulic damping system can effectively absorb vibration energy. The damping force generated by the hydraulic oil 715 flowing through the fine holes 713 achieves smooth shock absorption, ensuring the stability of the cabinet in a vibration environment.

[0029] Figure 1 , Figure 2 As shown, four columns 12 are symmetrically fixedly connected to the top of the base 1 on the outside of the cabinet body 3. A synchronous drive assembly located at the bottom and outside of the cabinet body 3 is installed between the four columns 12. Screw lifting assemblies located on the outside of the cabinet body 3 are installed at both movable ends of the synchronous drive assembly. The synchronous drive assembly includes two crossbars 83, which are fixedly connected to two adjacent columns 12. Synchronous pulleys 81 are rotatably connected to the top of each of the two crossbars 83. A synchronous belt 82 meshes between the two synchronous pulleys 81. A motor 84 is fixedly connected to the bottom of each crossbar 83. The drive shaft of the motor 84 passes through the crossbar 83 and is fixedly connected to the adjacent synchronous pulley 81. Both screw lifting assemblies include a screw body 22, and a movable seat 21 is threaded onto the outer surface of the screw body 22. Two movable rods 23 are symmetrically fixedly connected to the top of the movable seat 21. This synchronous drive mechanism drives the synchronous pulleys 81 via the motor 84 to achieve synchronous rotation of the screws on both sides, ensuring coordinated operation of the anti-tipping device and improving system reliability.

[0030] Figure 1 , Figure 5As shown, the two movable ends of the two screw lifting assemblies are equipped with synchronous transmission assemblies located outside the cabinet body 3. The two movable ends of the four synchronous transmission assemblies are respectively fixedly connected to the first side support rod 5 and the second side support rod 6 located outside the cabinet body 3. Each of the four synchronous transmission assemblies includes a housing 41, and the housing 41 is slidably sleeved on the outer surface of the adjacent movable rod 23. The housing 41 has two racks 43 inside, and the racks 43 are fixedly connected to the movable rod 23. The outer surfaces of the two racks 43 are meshed with gears 42. One end of the gear 42 is fixedly connected to a connecting shaft 44, and the connecting shaft 44 is fixedly connected to the adjacent first side support rod 5 and the adjacent second side support rod 6. The outer surfaces of the two connecting shafts 44 are limited to rotate and sleeved with mounting seats 45. The mounting seats 45 are fixedly connected to the housing 41 and the adjacent column 12. The gear 42 and rack 43 transmission mechanism converts the linear motion of the screw into the rotational motion of the support rod, ensuring that the support rod can quickly and accurately unfold to the preset angle to form a stable anti-tipping support structure.

[0031] Figure 3 As shown, all four columns 12 are fixedly connected to the cabinet body 3 with a second shock-absorbing spring 10. The setting of the second shock-absorbing spring 10 further enhances the overall shock absorption performance of the system, forming a multi-level shock absorption protection.

[0032] Figure 4 As shown, a vibration sensor 11 is fixedly installed on one side of the top of the base 1. This sensor can monitor the vibration in real time and provide an accurate trigger signal for the anti-tipping system. The vibration sensor 11 is a Bosch BMA456, a high-precision digital accelerometer with a built-in intelligent motion detection algorithm, which is suitable for use in this application.

[0033] Figure 1-6 As shown, in use, an existing controller can be installed. The controller is electrically connected to the vibration sensor 11 and the motor 84 to form a control system, which is beneficial for controlling the overall operation. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in combination with common knowledge.

[0034] Shock absorption and cushioning working principle: When the cabinet body 3 is subjected to vibration, the first damping spring 9 at the bottom first absorbs the vertical impact energy, achieving primary buffering through elastic deformation. Simultaneously, the vibration energy is transmitted to the connecting rod assembly via the cross seat 73, forcing the connecting rod body 72 to move the slide rod 711 of the hydraulic damper 71. The piston 714 squeezes the hydraulic oil 715 within the cylinder 712. The hydraulic oil 715 generates a throttling damping effect through the fine orifice 713, converting kinetic energy into heat energy for dissipation, achieving adaptive attenuation of horizontal vibration energy. The second damping spring 10 between the column 12 and the cabinet forms a two-stage damping system. These multi-stage damping mechanisms work together to ensure the stability of electrical components under continuous vibration.

[0035] Active anti-tipping working principle: Vibration sensor 11 monitors the vibration state of the cabinet body 3 in real time. When the detected vibration intensity exceeds the preset earthquake threshold, it immediately sends a trigger signal to the control system. Upon receiving the signal, the control system immediately starts motor 84. Motor 84 drives synchronous pulley 81 to rotate via drive shaft, and synchronous belt 82 drives another synchronous pulley 81 to rotate synchronously. The two synchronous pulleys 81 drive screw body 22 to rotate respectively. When screw body 22 rotates, it drives movable seat 21 to move along screw axis. Movable seat 21 drives movable rod 23 to move vertically. Movable rod 23 pushes two racks 43 inside housing 41 to rise, driving two gears 42 to rotate. The two gears 42 drive the first side support rod 5 and the second side support rod 6 to unfold via connecting shaft 44 connected to them, until the first side support rod 5 and the second side support rod 6 contact the ground, and the support rods and the ground form a stable triangular support structure.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
