Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to an anti-collision distribution box. Background Art

[0002] The distribution box is a key device in the power system. Its structure and structural principle ensure the safe operation of the circuit. The structure of the distribution box includes a shell, a main switch, a branch circuit breaker and a grounding device. The shell is used to protect the internal electrical components, the main switch controls the power supply of the entire circuit, the branch circuit breaker distributes the power to different circuits or equipment, and the grounding device introduces residual current to protect personnel and equipment. The structural principle of the distribution box is reflected in the distribution of power, overload protection, short circuit protection, grounding protection and isolation circuit.

[0003] For example, a collision-proof distribution box for construction disclosed in the authorization announcement number CN219739702U includes a base and a box body, a universal ball is embedded inside the base, and damping rods are fixedly installed at the top and bottom of the universal ball. The peripheral sides of the two damping rods are sleeved with a first spring, and the top of the damping rod at the top is fixedly connected to the box body. A blocking ring capsule and a group of second springs distributed in a circular array are respectively installed between the relative surfaces of the box body and the base. Through the arrangement of the first spring and the blocking ring capsule, on the one hand, it can effectively limit the position of the box body in a static state, and on the other hand, it enables the box body to perform universal elastic buffering when it is impacted. However, the initial damping force of each shock-absorbing and collision-proof structure in this technical solution is limited by the spring material, elastic force and other reasons, resulting in the non-adjustable collision resistance, which will cause the distribution box to fail to provide sufficient protection under certain operating conditions, increasing the safety risks of circuits and equipment, especially in high collision intensity environments. It is difficult for the collision-proof distribution box to effectively reduce the collision force, thereby failing to protect the internal electrical equipment from damage or fire hazards.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides an embodiment: an anti-collision distribution box, comprising a distribution box unit 1 and four support plates 5 fixed on the outer walls of both sides of the distribution box unit 1, a parallel connecting rod support structure 6 is installed on the outer wall of one side of the support plate 5, and anti-collision plates 9 are installed on the two parallel connecting rod support structures 6 in the same Y-axis direction, and a bending portion is provided at one end of the two anti-collision plates 9 close to each other;

[0020] A C-shaped block 7 is slidably mounted on the surface of the support plate 5 below the parallel link support structure 6. Hydraulic dampers 8 for interconnecting with the movable ends of the parallel link support structure 6 are hinged on the outer walls on both sides of the C-shaped block 7. Z-axis bidirectional push-pull mechanisms 10 are installed on both inner walls of the distribution box monomer 1. The Z-axis bidirectional push-pull mechanisms 10 are used to drive the two C-shaped blocks 7 to move toward each other in the same Z-axis direction.

[0021] A rain cover 2 is fixed on the top of the distribution box monomer 1. The cross-sectional shape of the rain cover 2 is an isosceles trapezoid. A box door 3 is installed on one side of the surface of the distribution box monomer 1 through a hinge.

[0022] A distribution unit 4 is installed on the inner wall of one side of the distribution box monomer 1. The distribution unit 4 includes a main switch, a circuit breaker, a fuse, a grounding wire, a relay, a voltmeter and an ammeter. The main switch and the branch circuit breaker cooperate to achieve power distribution. The circuit breaker and the fuse cut off the power supply when the current is abnormal to prevent overload or short circuit. The grounding device introduces residual current to protect safety. At the same time, the electrical components such as the relay, voltmeter and ammeter inside the distribution box monitor and control the circuit operation status.

[0023] The Z-axis bidirectional push-pull mechanism 10 includes a screw bidirectional module 1001 installed on the inner wall of one side of the distribution box monomer 1, and rectangular sliders 1002 installed on the two movable ends of the screw bidirectional module 1001, one end of the rectangular slider 1002 penetrates the outside of the distribution box monomer 1 and is fixed with a cross arm 1003, one end of the cross arm 1003 is fixedly connected to the outer wall of one side of the C-shaped block 7, and during the operation of the Z-axis bidirectional push-pull mechanism 10, the screw bidirectional module 1001 drives the rectangular slider 1002, the cross arm 1003 and the C-shaped block 7 to slide;

[0024] When adjusting the initial length of the hydraulic damper 8, the staff turns on the screw bidirectional module 1001 to work, and the two nut pairs of the screw bidirectional module 1001 respectively drive the C-shaped block 7 to move up and down. At this time, the C-shaped block 7 and the support plate 5 slide relative to each other. By changing the initial position of the C-shaped block 7, the length of the hydraulic damper 8 is indirectly adjusted, and its anti-collision performance can be changed without replacing the distribution box, reducing the cost of maintenance and replacement of equipment;

[0025] Slide grooves 101 are provided on both sides of the outer wall of the power distribution box unit 1. A rectangular slider 1002 is slidably installed inside the slide grooves 101. The slide grooves 101 guide and limit the sliding of the rectangular slider 1002.

[0026] The parallel connecting rod support structure 6 includes two Y-shaped forks 601 hinged in parallel on the outer wall of one side of the support plate 5, and a vertical arm 602 hingedly installed at the top of the two Y-shaped forks 601. The anti-collision plate 9 is fixed on the outer wall of one side of the vertical arm 602. The top of the piston rod of the hydraulic damper 8 is hinged to the outer wall of one side of the vertical arm 602. When the anti-collision plate 9 is hit, the anti-collision plate 9 forces the vertical arm 602 and the Y-shaped fork 601 to swing. During this process, the hydraulic damper 8 is stretched. The damper can absorb part of the collision energy and reduce the impact force of the collision, thereby protecting the internal electrical equipment from damage.

[0027] When the embodiment of the present application is in use, the staff first arranges the anti-collision distribution box at the point to be used. The distribution unit 4 includes a main switch, a circuit breaker, a fuse, a grounding wire, a relay, a voltmeter and an ammeter, etc. When an impact occurs in the side wall direction of the distribution box monomer 1, the external impactor first collides with the anti-collision plate 9, and then the two anti-collision plates 9 on the same side wall are subjected to force and move away from each other. At this time, the parallel connecting rod support structure 6 and the hydraulic damper 8 are deformed. In this process, the hydraulic damper 8 provides a deflection resistance and performs a damping buffering on the impact force. When the impact process is over, the hydraulic damper 8 enables the anti-collision plate 9 to automatically reset its position after the external force is lost, thereby achieving a better anti-collision buffering effect, and successively reducing the impact force of the distribution box monomer 1. When When the initial resistance of the hydraulic damper 8 needs to be changed, the staff starts the Z-axis bidirectional push-pull mechanism 10 to work, and the Z-axis bidirectional push-pull mechanism 10 pulls the two C-blocks 7 in the same vertical direction to move toward each other, that is, the two C-blocks 7 move closer to or away from each other, and the C-block 7 pulls the hydraulic damper 8 to deform, thereby adjusting the initial stretching length of the hydraulic damper 8 and flexibly changing the anti-collision resistance of the anti-collision distribution box. This enables the distribution box to better adapt to different collision environments and force requirements, improves its adaptability and flexibility, and by adjusting the anti-collision resistance, the distribution box can provide appropriate protection in different collision situations, which can not only effectively reduce the impact caused by minor collisions, but also provide sufficient protection in severe collisions, thereby improving the safety of the distribution box.
