Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, in particular to a high-strength earthquake-resistant distribution cabinet. Background Technique

[0002] A distribution cabinet is a device used in the power system, mainly for distributing and controlling electric energy. As an important part of the power system, its main function is to distribute and control electric energy. The inside of the distribution cabinet contains multiple electrical components, such as circuit breakers, switches, protection devices, measuring instruments, etc. These components can realize the control, distribution, protection and monitoring of electric energy. The distribution cabinet plays a key role in the power system, ensuring the efficient and safe distribution of electric energy, and providing protection for the circuit to avoid damage to the power system and electrical equipment caused by electrical faults such as overload and short circuit. When designing and configuring the distribution cabinet, factors such as electrical safety standards, load requirements, maintenance convenience, and environmental conditions need to be considered.

[0003] A temporary distribution cabinet is a kind of distribution cabinet, usually used in construction sites, outdoor activities, temporary facilities or emergencies to provide temporary power distribution and control. These cabinets are designed flexibly and can be quickly deployed and disassembled to adapt to changing power consumption needs and environments. They are usually lighter than permanently installed distribution cabinets and are easy to move and install.

[0004] Existing temporary distribution cabinets usually have a high protection level, such as IP level, to prevent water and dust from entering. Although they meet the usage requirements to a certain extent, it is found in the actual use process that other equipment running in the usage environments such as construction sites, outdoor activities, and temporary facilities will cause the ground to vibrate violently, and distribution cabinets with poor earthquake resistance will suffer physical damage, such as cabinet deformation, screw loosening, electrical connection disconnection, etc. This will not only affect their normal functions, but may also lead to the complete damage of the equipment. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-strength earthquake-resistant distribution cabinet to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a high-strength earthquake-resistant distribution cabinet, including an earthquake-resistant mechanism, an outer frame mechanism is fixedly installed at the top of the earthquake-resistant mechanism, an inner box mechanism is fixedly installed at the top of the earthquake-resistant mechanism through the outer frame mechanism, the earthquake-resistant mechanism includes a mounting plate, two groups of damping rods are fixedly installed at the bottom of the mounting plate, a counterweight seat is fixedly installed at the bottom of the mounting plate through the damping rods, positioning holes are opened at the four corners of the counterweight seat, ground nails are movably installed inside the positioning holes, four groups of limiting columns are fixedly installed at the bottom of the mounting plate and the top of the counterweight seat, and springs are sleeved on the outer walls of the limiting columns.

[0007] Preferably, a rubber pad is fixedly installed at the bottom of the counterweight seat, and a plurality of anti-slip grooves are formed at the bottom of the rubber pad.

[0008] Preferably, a manipulation hole is formed at the top of the ground nail, and a plurality of anti-slip protrusions are fixedly installed on the outer wall of the ground nail.

[0012] Preferably, a rain shield is fixedly installed on the top of the top plate, and a handle is fixedly installed on the top of the rain shield.

[0013] Compared with the prior art, the beneficial effects of the present utility model are: the high-strength earthquake-resistant power distribution cabinet;

[0014] 1. By the method of fixedly installing the counterweight seat on the ground through a plurality of ground nails penetrating the positioning holes, the fixation of the equipment is completed. The overall center of gravity of the equipment is lowered by the counterweight seat to improve the earthquake resistance of the equipment. When vibration occurs, the spring first absorbs the vibration energy transmitted from the environment to the counterweight seat and allows the structure to have a certain displacement, and then the damping rod suppresses this displacement by consuming energy, reducing the vibration amplitude of the structure, and protecting the inner box mechanism on the top of the mounting plate;

[0015] In the above process, the compression degree of the spring is restricted by two groups of limit columns on the same vertical line to prevent the spring and the damping rod from being over-compressed and damaged. The dust-proof sleeve is used to protect the damping rod to improve the durability of the damping rod. At the same time, the rubber pad is used to separate the ground and the counterweight seat to reduce the influence of ground vibration on the equipment, and the anti-slip protrusions and anti-slip grooves are used to increase the friction between the ground nail and the rubber pad and the ground, making the equipment more firmly fixed. Then, the ground nail can be easily pulled out by the user through the manipulation hole;

[0016] 2. The set sealing protection door effectively prevents dust, moisture, and rain from entering the interior of the power distribution cabinet, protecting electrical components from the risks of corrosion and short circuits. The overall strength of the power distribution cabinet is enhanced through the reinforcing ribs, thereby improving the seismic performance and reducing the risk of equipment damage. A protective shell is formed outside the inner box mechanism through the cooperation among the top plate, mounting plate, and damping rod, further increasing the structural strength of the equipment. The rain shield prevents rain from directly falling on the top of the power distribution cabinet, reducing the chance of rain penetration and water accumulation, protecting the internal equipment, and the handle facilitates the movement of the power distribution cabinet, making it easier to reposition or temporarily transfer when needed.

[0027] The specific implementation method is as follows: The counterweight base 303 is fixedly installed on the ground by passing a number of ground nails 307 through the positioning holes 306 to complete the fixation of the equipment. The center of gravity of the whole equipment is lowered by the counterweight base 303 to improve the earthquake resistance of the equipment. When vibrations occur, the springs 305 first absorb the vibration energy transmitted from the environment to the counterweight base 303 and allow the structure to have a certain displacement, and then the damping rods 302 suppress this displacement by consuming energy, reducing the vibration amplitude of the structure, and protecting the inner box mechanism 1 on the top of the mounting plate 301;

The dust-proof sleeve 312 is used to protect the damping rods 302 to improve the durability of the damping rods 302. At the same time, the ground and the counterweight base 303 are separated by the rubber pad 308 to reduce the impact of ground vibrations on the equipment.

[0031] A rain shield 203 is fixedly installed at the top of the top plate 201. A handle 204 is fixedly installed at the top of the rain shield 203.

[0032] The implementation method is specifically as follows: The sealed protective door 102 effectively prevents dust, moisture and rain from entering the interior of the power distribution cabinet, protects the electrical components from the risks of corrosion and short circuit, and improves the overall strength of the power distribution cabinet through the reinforcing ribs 104, thereby enhancing the seismic performance and reducing the risk of equipment damage. A protective shell is formed outside the inner box mechanism 1 through the cooperation among the top plate 201, the mounting plate 301 and the damping rods 302, further increasing the structural strength of the equipment. Then, the rain shield 203 prevents rain from directly falling on the top of the power distribution cabinet, reducing the chance of rain penetration and water accumulation, protecting the internal equipment, and the handle 204 facilitates the movement of the power distribution cabinet, making it easier to re-arrange or temporarily transfer when needed.

[0033] Working principle: When using this high-strength seismic-resistant power distribution cabinet, the counterweight base 303 is fixedly installed on the ground by passing a plurality of ground nails 307 through the positioning holes 306 to complete the fixation of the equipment. The center of gravity of the whole equipment is lowered by the counterweight base 303 to improve the seismic resistance of the equipment. When vibration occurs, the spring 305 first absorbs the vibration energy transmitted from the environment to the counterweight base 303 and allows the structure to have a certain displacement, and then the damping rods 302 suppress this displacement by consuming energy, reducing the vibration amplitude of the structure and protecting the inner box mechanism 1 on the top of the mounting plate 301;

The damping rods 302 are protected by dust-proof sleeves 312 to improve the durability of the damping rods 302. At the same time, the ground and the counterweight base 303 are separated by rubber pads 308 to reduce the influence of ground vibration on the equipment, and the friction between the ground nails 307 and the rubber pads 308 is increased by anti-slip protrusions 310 and anti-slip grooves 311, making the equipment fixed more firmly.

The overall strength of the power distribution cabinet is enhanced by the reinforcing rib 104, thereby improving the seismic performance and reducing the risk of equipment damage. A protective shell is formed outside the inner box mechanism 1 through the cooperation among the top plate 201, the mounting plate 301 and the damping rod 302, further increasing the structural strength of the equipment. The rain-proof top 203 prevents rain from directly falling on the top of the power distribution cabinet, reducing the chance of rain penetration and water accumulation, protecting the internal equipment.
