Description

Technical Field

[0001] This utility model relates to the field of electrical engineering equipment technology, and in particular to an anti-vibration power distribution cabinet. Background Technology

[0002] Currently, the power distribution boxes widely used in data centers and critical facilities generally adopt a dual power supply scheme of "one main and one backup," employing dual mains power or one mains power combined with one diesel generator (generator). When the main power supply circuit fails, automatic transfer switches (ATS) or manual operation are required to switch power to maintain load power. Structurally, these devices are typically made of cold-rolled steel plates welded together, and their protection rating generally meets the requirements of IP2X for indoor environments and IP55 for outdoor environments, and has basic seismic resistance design capabilities.

[0003] However, existing distribution boxes have significant shortcomings. First, in scenarios involving mains power outages, especially when using a "mains power + generator" solution, the switching action of the ATS (Automatic Switching System) combined with the start-up time of the diesel generator typically results in a power restoration delay of 3-4 seconds. This time window exceeds the tolerance limits of some critical loads with extremely high requirements for power continuity (such as high-performance computing servers and core network equipment), posing a risk of business interruption. Second, for facilities located in areas with frequent crustal activity and high earthquake risk, the existing distribution box foundation seismic design may not meet higher levels of seismic fortification requirements, posing a risk of equipment damage and secondary power outages. Therefore, it is urgent to improve the power switching speed and the seismic performance of the equipment itself.

[0004] In view of this, based on years of experience in production and design in this and related fields, the inventor has designed an anti-vibration power distribution cabinet through repeated experiments in order to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-vibration power distribution cabinet that can effectively improve the stability and robustness of the power distribution cabinet.

[0006] To achieve the above objectives, this utility model proposes an earthquake-resistant power distribution cabinet, wherein the earthquake-resistant power distribution cabinet includes a cabinet body and a door panel. The cabinet body has an opening, and a door frame is provided at the opening. The door panel is closable and installed on the door frame. A locking device is provided on the inner wall surface of the door panel. The locking device includes a driving mechanism and multiple latching mechanisms. The multiple latching mechanisms are arranged sequentially and at intervals along one side of the door panel. Each latching mechanism includes at least a base and a pin. The pin is slidably engaged with the base. The driving mechanism is connected to the multiple pins and drives the end of the pin to extend out of the side of the door panel and press against the cabinet body.

[0007] As described above, in the earthquake-resistant power distribution cabinet, the drive mechanism includes at least a gear, a rack, a connecting rod, and multiple swing arms. The gear is rotatably mounted on the inner panel of the door panel. The rack is slidably mounted on the door panel and meshes with the gear. The connecting rod is fixed to the rack and moves synchronously with the rack. The multiple swing arms are respectively matched with multiple locking mechanisms. One end of each swing arm is hinged to the connecting rod, and the other end of each swing arm is hinged to the pin.

[0008] As described above, in the earthquake-resistant power distribution cabinet, a lock body is provided on the inner panel, a lock cylinder is provided in the lock body, a keyhole is provided on the door panel to align with the lock cylinder, a gear is rotatably mounted on the lock body, and the gear is aligned with the paddle or cam of the lock cylinder. When the key rotates the paddle or cam of the lock cylinder, the gear rotates.

[0009] In the earthquake-resistant power distribution cabinet described above, the rack is fixedly connected to the connecting rod via a connecting piece, and a guide structure is provided on the inner plate surface. The guide structure slides with the connecting rod and restricts the connecting rod to move only up and down.

[0010] As described above, the earthquake-resistant power distribution cabinet has multiple lock seats on its body, and the multiple lock seats are aligned and cooperate with multiple locking mechanisms, with the pins inserted into the lock seats.

[0011] As described above, the seismic-resistant distribution cabinet is composed of multiple sealing plates, and a reinforcing frame is provided inside the cabinet. The reinforcing frame is fixedly connected to the multiple sealing plates and supports the sealing plates.

[0012] The earthquake-resistant power distribution cabinet described above is a double-layer cabinet.

[0013] The earthquake-resistant distribution cabinet described above includes at least a circuit breaker and a voltage relay inside the cabinet.

[0014] In the earthquake-resistant distribution cabinet described above, the circuit breaker is a fast-acting circuit breaker or a frame circuit breaker.

[0015] The earthquake-resistant distribution cabinet described above also includes a voltage transformer inside the cabinet.

[0016] Compared with the prior art, the present invention has the following features and advantages:

[0017] The earthquake-resistant power distribution cabinet proposed in this utility model uses multiple locking mechanisms of the locking device to fix the door panel to the cabinet body. These multiple locking mechanisms create multiple rigid connection points between the door panel and the cabinet body, ensuring the door panel and cabinet body are tightly locked together on this side. This significantly reduces the clearance between the door panel and the cabinet body, improves the inconsistent door gaps, and guarantees the protective performance of the earthquake-resistant power distribution cabinet. Especially under the severe shaking and torsional deformation caused by an earthquake, the multi-point rigid connection effectively prevents the door panel from accidentally popping open, shaking, or even falling off due to deformation or inertial forces, maintaining the sealed integrity of the earthquake-resistant power distribution cabinet.

[0026] The details of this utility model can be more clearly understood by referring to the accompanying drawings and the description of specific embodiments. However, the specific embodiments of this utility model described herein are for illustrative purposes only and should not be construed as limiting the utility model in any way. Under the teachings of this utility model, those skilled in the art can conceive of any possible modifications based on this utility model, and these should all be considered to fall within the scope of this utility model.

[0027] like Figures 1 to 5 As shown, this utility model proposes an earthquake-resistant power distribution cabinet 100, which includes a cabinet body 10 and a door panel 20. The cabinet body 10 has an opening, and a door frame is provided at the opening. The door panel 20 is installed on the door frame in an openable and closable manner. A locking device 30 is provided on the inner panel surface of the door panel 20. The locking device 30 includes a drive mechanism 31 and a plurality of latching mechanisms 32. The plurality of latching mechanisms 32 are arranged sequentially and spaced along one side of the door panel 20. Each latching mechanism 32 includes at least a base 321 and a pin 322. The pin 322 is slidably engaged with the base 321. The drive mechanism 31 is connected to the plurality of pins 322 and drives the end of the pin 322 to extend out of the side of the door panel 20 and press it against the cabinet body 10.

[0028] The earthquake-resistant power distribution cabinet 100 proposed in this utility model uses multiple locking mechanisms 32 of the locking device 30 to fix the door panel 20 to the cabinet body 10. These multiple locking mechanisms 32 form multiple rigid connection points between the door panel 20 and the cabinet body 10, ensuring that the door panel 20 and the cabinet body 10 are tightly locked together on this side. This significantly reduces the movement gap between the door panel 20 and the cabinet body 10, improves the inconsistent door gaps between the door panel 20 and the cabinet body 10, and ensures the protective performance of the earthquake-resistant power distribution cabinet 100. Especially under the severe shaking and torsional deformation caused by an earthquake, the multi-point rigid connection effectively prevents the door panel 20 from accidentally popping open, shaking, or even falling off due to deformation or inertial forces, maintaining the closed integrity of the earthquake-resistant power distribution cabinet 100.

[0029] In an optional embodiment of this utility model, the drive mechanism 31 includes at least a gear 311, a rack 312, a connecting rod 313, and a plurality of rocker arms 314. The gear 311 is rotatably mounted on the inner panel of the door panel 20. The rack 312 is slidably mounted on the door panel 20 and meshes with the gear 311. The connecting rod 313 is fixed to the rack 312 and moves synchronously with the rack 312. The plurality of rocker arms 314 are respectively connected to a plurality of locking mechanisms 32 one by one. One end of each rocker arm 314 is hinged to the connecting rod 313, and the other end of each rocker arm 314 is hinged to the pin 322 of the locking mechanism 32. With the above structure, each locking mechanism 32 is driven synchronously by the swing rod 314 and the connecting rod 313, which ensures that multiple locking mechanisms 32 can lock the door panel 20 synchronously. This ensures that all rigid connection points on the side of the door panel 20 are subjected to uniform force and move in a consistent manner, so that the clamping force between the door panel 20 and the cabinet 10 is evenly distributed, effectively preventing door panel deformation or poor sealing caused by local stress concentration, and greatly improving sealing performance and overall rigidity.

[0030] In the earthquake-resistant power distribution cabinet 100 proposed in this utility model, multiple bases 321 and multiple pins 322 are driven by the drive mechanism 31 to move synchronously, thereby realizing the synchronous locking of the cabinet 10 and the door panel 20 at multiple points.

[0031] In one optional embodiment of this utility model, a lock body is provided on the inner plate, a lock cylinder is provided in the lock body, a keyhole is provided on the door plate to align with the lock cylinder, a gear 311 is rotatably mounted on the lock body, and the gear 311 is aligned with the lever or cam of the lock cylinder. When the key rotates the lock cylinder, the lever or cam of the lock cylinder drives the gear 311 to rotate.

[0032] In an optional embodiment, the rack 312 is fixedly connected to the connecting rod 313 via a connecting piece, and a guide structure is provided on the inner plate surface. The guide structure slides with the connecting rod 313 and restricts the connecting rod 313 to move only up and down.

[0033] In another optional example of this embodiment, the rack 312 and the connecting rod 313 are connected at a single point via a rocker arm. This structure can be fixed and rotated at a single point. While the gear 311 drives the connecting rod 313 to move up and down, each pin 322 moves back and forth accordingly, thereby achieving a multi-point locking effect.

[0034] In another optional embodiment of this utility model, a handle is provided on the door panel, and the gear 311 is fixedly connected to the handle by screws. When it is necessary to lock and open, the gear 311 is manually driven to rotate by the door handle.

[0035] In one optional embodiment of this utility model, a plurality of locking mechanisms 32 are arranged on the vertical side of the door panel 20 and are spaced apart sequentially from top to bottom.

[0036] In one optional embodiment of this utility model, an inner sealing plate 21 is provided on the inner panel surface of the door panel 20, and an inner sealing plate 22 is fixedly stacked on the inner panel surface, thereby strengthening the door panel 20 and further improving the door panel 20's resistance to torsion.

[0037] In an optional example of this embodiment, the inner sealing plate 22 is made of high-quality Q235 steel plate. The structure of the inner sealing plate 22 adopts a multi-folded edge method, which enhances the overall strength of the inner sealing plate 22. The inner sealing plate 22 is connected to the door panel 20 by riveting. While avoiding the position of the connecting rod 313, it is made as large as possible. The above-mentioned double-layer door assembly structure can effectively prevent the door from deforming during transportation and use, and enhance its service life.

[0038] In one optional embodiment of this utility model, the locking device 30 is fixed to the door panel 20 at multiple points by a pressure plate.

[0039] In one optional embodiment of this utility model, after the latch 322 of the locking mechanism 32 is locked in place with the cabinet 10, the latch 322 also has a certain damping effect.

[0040] In one optional embodiment of this utility model, the cabinet 10 is formed by multiple sealing plates 11, and a reinforcing frame 12 is provided inside the cabinet 10. The reinforcing frame 12 is fixedly connected to the multiple sealing plates 11 and supports the sealing plates 11. The rigidity and seismic performance of the cabinet 10 are further improved by the supporting frame 12.

[0041] In another optional embodiment of this utility model, the cabinet 10 is a double-layer cabinet, which can also improve the rigidity and seismic performance of the cabinet 10.

[0042] In an optional embodiment of this utility model, the earthquake-resistant power distribution cabinet 100 further includes a base 40, and the cabinet body 10 is mounted on the base 40.

[0043] Furthermore, the base 40 also adopts a rigid frame structure.

[0044] In one optional embodiment of this utility model, the cabinet 10 is provided with at least a circuit breaker and a voltage relay (not shown in the figure).

[0045] In one alternative example of this implementation, the circuit breaker is a fast-acting circuit breaker or a frame circuit breaker.

[0046] In one optional embodiment of this utility model, a voltage transformer is also provided inside the cabinet 10.

[0047] The earthquake-resistant distribution cabinet 100 proposed in this invention can reduce switching time. In one optional example, the earthquake-resistant distribution cabinet 100 can achieve a switching time of 20ms. Compared with the existing ATS switching switches with larger currents, which have a switching time of at least 80ms, the earthquake-resistant distribution cabinet 100 of this invention can open and close within 20ms, thereby achieving seamless power outage for most loads. This performance is achieved through the seamless switching circuit breaker in the distribution cabinet.

[0048] In one optional embodiment of this utility model, the seismic-resistant distribution cabinet 100 mainly includes a circuit breaker, a UPS power supply, a data acquisition module, a cabinet door air conditioner, and a relay protector. To improve the seismic resistance of the cabinet, the main equipment inside the cabinet is reinforced during installation and fixed at multiple points.

[0049] The detailed explanations of the above embodiments are intended only to explain the present invention so as to facilitate a better understanding of the present invention. However, these descriptions should not be construed as limiting the present invention for any reason. In particular, the various features described in different embodiments can be arbitrarily combined with each other to form other embodiments. Unless there is an explicit description to the contrary, these features should be understood to be applicable to any embodiment, and not limited to the described embodiments.
