Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for microgrids, specifically a safety protection device for microgrids. Background Technology

[0002] A microgrid is a small-scale power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. The purpose of microgrids is to realize the flexible and efficient application of distributed power sources and solve the grid connection problem of a large number of diverse distributed power sources. Traditional microgrid safety protection plates are fixed to the outside of the microgrid box with screws, which is extremely difficult to install and disassemble, making it difficult for users to maintain and replace the microgrid box. Moreover, there is no buffer device, and external impacts can easily cause the microgrid box and the protection plate to collide and be damaged, which is not conducive to the protection of the microgrid.

[0003] In the prior art, patent application number CN202021457428.6 proposes a solution using an external protective net. The outer shell of the protective net is fixed to both sides of the microgrid box by a patented design device, which has a buffering function. However, it has the following shortcomings:

[0004] 1. The protective netting has weak perimeter protection, and its protective effect is poor when the edges are impacted;

[0005] 2. The device lacks positioning and fastening in the front and rear directions, making the outer casing prone to loosening from the microgrid box under external force;

[0006] 3. The front surface of the protective netting shell is simply connected to the left and right sides, making it prone to deformation when subjected to lateral impact or force.

[0007] 4. The protective net shell requires adjustment of multiple self-locking nuts to be properly installed, which is cumbersome. Utility Model Content

[0008] The purpose of this utility model is to provide a safety protection device for microgrids, which plays a safety protection role for microgrid boxes; and under the action of external force, the protective mechanism is not easy to loosen from the microgrid box, and the microgrid box is not easy to deform when it is impacted from the side or by lateral force; at the same time, the operation is simple and quick.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for microgrids, comprising a microgrid box with a front door and a protective mechanism mounted on the microgrid box. The protective mechanism includes right-angle frames, connecting seats, protective rods, and a protective net. There are four right-angle frames, each vertically positioned at one of the four corners of the microgrid box and attached to it. The connecting seats are vertically symmetrically arranged in pairs on the left and right sides and rear of the microgrid box. Two connecting seats on each side of the microgrid box are fixedly connected to two right-angle frames on each side, and the connecting seats are perpendicular to the right-angle frames. The protective rods are arranged sequentially from top to bottom between two adjacent connecting seats, with both ends of the protective rods penetrating the two adjacent connecting seats and secured with nuts. The protective net is located in front of the box door, and buffer mechanisms are symmetrically arranged on both sides of the protective net. Two buffer mechanisms are symmetrically arranged on the right-angle frames on both sides of the box door.

[0010] To ensure the safety of the microgrid box, a preferred safety protection device for microgrids according to this utility model includes a buffer mechanism comprising a buffer frame, a buffer seat, a spring, and a guide rod. The buffer frame is vertically mounted on a right-angled frame, with a buffer groove extending along its height on the side of the right-angled frame facing the protective net. The buffer seat is vertically positioned within the buffer groove, with one side extending to the outside of the buffer groove. The spring is located within the buffer groove, with both ends fixedly connected to the inner wall of the buffer groove and the buffer seat, respectively. One end of the guide rod is positioned within the buffer groove, and the other end passes through the spring and the buffer seat, secured with a nut. The protective net is located between two buffer frames, on the side of the buffer seat furthest from the box door. One buffer seat intersects with one side of the protective net, allowing the protective net to rotate around the intersection point. The other buffer seat and the protective net are respectively equipped with a lock and a buckle.

[0011] To prevent the microgrid box from being hit by collisions, as a preferred safety protection device for microgrids according to this utility model, the number of protective bars on each side of the microgrid box is not less than five.

[0012] To achieve a rainproof effect, as a preferred safety protection device for microgrids according to this utility model, the height of the right-angle frame is greater than the height of the microgrid box, and a rainproof canopy is provided above the right-angle frame.

[0013] To facilitate the assembly and disassembly of the rain shelter, as a preferred safety protection device for microgrids according to this utility model, the bottom of the rain shelter is provided with four card seats that correspond one-to-one with the right-angle frame. The bottom of the card seat is provided with a card slot that is adapted to the right-angle frame, and the upper end of the right-angle frame is inserted into the card slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model incorporates a protective net, protective rods on the left, right, and rear sides of the microgrid box, and a right-angle frame to form a complete enclosure. This enclosure provides comprehensive protection for the microgrid box, ensuring its safety when impacted from any direction. Furthermore, the protective mechanism is resistant to detachment from the microgrid box under external forces, and the box is less prone to deformation when subjected to lateral or side impacts. Operation is also simple and quick.

[0016] Furthermore, the protective netting can be opened, making it easy to periodically inspect and maintain the interior of the microgrid box;

[0017] Meanwhile, the protective mechanism is easy to install and disassemble, which is beneficial for the maintenance and replacement of the safety protection device for the microgrid. Attached Figure Description

The protective mechanism includes right-angle brackets 3, connecting seats 4, protective rods 5, and protective nets 6. There are four right-angle brackets 3, which are vertically mounted at the four corners of the microgrid box 2 and attached to them. The connecting seats 4 are vertically symmetrically arranged in pairs on the left and right sides and the rear of the microgrid box 2. The two connecting seats 4 on each side of the microgrid box 2 are fixedly connected to the two right-angle brackets 3 on each side, and the connecting seats 4 are perpendicular to the right-angle brackets 3.

The protective nets 6 are located in front of the door 1, and buffer mechanisms are symmetrically arranged on both sides of the protective nets 6. The two buffer mechanisms are symmetrically arranged on the right-angle brackets 3 on both sides of the door 1.

[0024] The buffer mechanism includes a buffer frame 7, a buffer seat 8, a spring 9, and a guide rod 10. The buffer frame 7 is vertically mounted on a right-angle frame 3. The right-angle frame 3 has a buffer groove 11 along its height on the side facing the protective net 6. The buffer seat 8 is vertically mounted in the buffer groove 11, and one side of the buffer seat 8 extends to the outside of the buffer groove 11. The spring 9 is located in the buffer groove 11, and both ends of the spring 9 are fixedly connected to the inner wall of the buffer groove 11 and the buffer seat 8, respectively. One end of the guide rod 10 is located in the buffer groove 11, and the other end of the guide rod 10 passes through the spring 9 and the buffer seat 8 and is fixed by a nut.

The mesh box 2 is not easily deformed when subjected to lateral impact or lateral force. When the protective mesh 6 is impacted, the protective mesh 6 and the buffer seat 8 can move radially along the guide rod 10. The compressed spring 9 provides elasticity to buffer the impact force, so that the protective mesh 6 provides safety protection for the microgrid box 2. One side of the protective mesh 6 is connected to a buffer seat 8. By opening the latch 12 and the buckle 13, the protective mesh 6 can be rotated open, and the box door 1 on the microgrid box 2 can be opened easily, which facilitates regular inspection and maintenance of the interior of the microgrid box 2. Moreover, the protective mechanism is easy to install and disassemble, which is conducive to the maintenance and replacement of the safety protection device for the microgrid.

[0027] As a technical optimization of this utility model, the number of protective rods 5 on each side of the microgrid box 2 is not less than five.

[0028] In this embodiment, multiple protective rods 5 are arranged sequentially from top to bottom, which further enables the protective rods 5 to protect the left and right sides and the rear of the microgrid box 2. The protection is thorough, and when the external impact hits the protective mechanism from any direction, it can play a safety protection role for the microgrid box 2.

[0029] As a technical optimization of this utility model, the height of the right-angle frame 3 is greater than the height of the microgrid box 2, and a rainproof canopy 14 is provided above the right-angle frame 3.

[0030] In this embodiment: the rain shelter 14 is installed on the top of the right-angle frame 3 so that the rain shelter 14 can protect the microgrid box 2 and the protective mechanism from rain and prevent rainwater from seeping into the microgrid box 2; the top of the rain shelter 14 is a four-sided pyramid shape.

[0034] Four right-angle brackets 3 are stably fixed to the four corners of the microgrid box 2. The right-angle brackets 3 and the connecting bases are integrally formed. The two ends of the protective rods 5 pass through the connecting bases 4 and are fixed with nuts, so that the four right-angle brackets 3 are stably fixed to the four corners of the microgrid box 2. The protective net 6 is set on the side of the microgrid box 2 with the box door 1 through the buffer mechanism on both sides. The protective net 6, the left and right sides and the rear of the microgrid box 2, and the right-angle brackets 3 form a frame, so that the microgrid box 2 is placed in the frame, making the microgrid box 2 well protected. When there is an external impact, the protective net 6, the protective rods 5 and the right-angle brackets 3 on the left and right sides of the microgrid box 2, form a frame, so that the microgrid box 2 is placed in the frame, making the microgrid box 2 well protected. When the microgrid box 2 is in any direction, it can provide safety protection for the microgrid box 2; when the protective net 6 is impacted, the protective net 6 and the buffer seat 8 can move in the radial direction of the guide rod 10, and the compressed spring 9 provides elasticity to buffer the impact force, so that the protective net 6 can provide safety protection for the microgrid box 2; one side of the protective net 6 is connected to a buffer seat 8, and the protective net 6 can be rotated open by opening the latch 12 and the buckle 13, and the box door 1 on the microgrid box 2 can be opened easily, which makes it easy to regularly inspect and maintain the inside of the microgrid box 2.
