Description

TECHNICAL FIELD

[0001] The utility model relates to the field of ring main unit, concretely is a base suitable for ring main unit installation. BACKGROUND

[0002] In the prior art, the base plays a crucial role in the installation and transfer process of the ring main unit. Currently, the installation method of the ring main unit is usually realized by relying on prefabricated bases. The design of these bases aims to provide a stable support platform for the ring main unit to facilitate its fixation and installation. By using the base, the ring main unit can be placed on the ground or other predetermined positions, thereby realizing the deployment and operation of electrical equipment.

[0003] Some technical solutions attempt to move the installation base to achieve the position transfer of the switch cabinet body. The core idea of this method is to move the base to drive the switch cabinet above it to move, thereby achieving flexible adjustment of the position to a certain extent. However, practice shows that this moving operation has significant shortcomings in stability. Especially during the moving process, once the ground appears to be bumpy or uneven, the installation base is prone to shaking. This shaking will be directly transmitted to the box loaded on it, causing the box to be subjected to unnecessary impact and vibration. In extreme cases, severe shaking may even cause damage to the box, and even more so, may cause the box to collapse, posing a potential risk to the safe operation of the equipment. SUMMARY

Specific implementation

[0022] The drawings are only for example description, and can not be understood as the limitation of the patent;In order to better illustrate the embodiment, some components of the drawings are omitted, enlarged or reduced, and do not represent the size of the actual product.

[0023] For those skilled in the art, it is understandable that some known structures in the drawings and their description can be omitted.The technical scheme of the utility model is further explained below in combination with the drawings and embodiments.

[0024] As shown in the drawings, Figs. 1-3 A base suitable for ring main unit installation, including support seat 1, the buffer platform 11 is slidably arranged on the support seat 1, and the first spring 12 is arranged between the buffer platform 11 and the support seat 1;The side of buffer platform 11 is provided with fulcrum 111, and the sliding rod 13 is fixed on the support seat 1, the driving block 14 is slidably arranged on the sliding rod 13, the transmission connecting rod 141 is connected between the driving block 14 and the fulcrum 111, and the driving block 14 and the fulcrum 111 are hinged with the transmission connecting rod 141, the trundle 16 for contacting the ground is fixedly connected to the lower end of the driving block 14, and the second spring 15 is arranged between the driving block 14 and the support seat 1;The axis of the first spring 12 is perpendicular to the axis of the second spring 15.

[0025] The buffer platform 11 is slidably mounted on the support base 1, allowing it to move to a certain extent in the vertical direction. This forms the basis of the vertical buffer. When the weight of the ring main unit presses on the buffer platform 11, or when it is subjected to a vertical impact, the first spring 12 is compressed, absorbing energy and providing a buffering effect. Vertical buffering effectively reduces the vibration and impact of the ring main unit in the vertical direction, protecting the equipment from damage. When the buffer platform 11 is tilted due to lateral force or uneven ground, the fulcrum 111 on the side of the buffer platform 11 will also move accordingly. The lateral force acting on the buffer platform 11 is transmitted to the drive block 14 through the transmission link 141, causing the drive block 14 to slide horizontally on the sliding rod 13 and compress the second spring 15. This achieves horizontal buffering of the buffer platform 11.

[0026] In a preferred embodiment, drive blocks 14 are provided on both sides of the support base 1. When the ring main unit is loaded on the buffer platform 11, the weight of the ring main unit will cause the buffer platform 11 to move closer to the support base 1. During this process, the fulcrum 111 of the buffer platform 11 will push the drive blocks 14 on both sides away from each other through the transmission connecting rod 141, thereby increasing the distance between the casters 16. Thanks to the increased distance between the casters 16, when moving the support base 1 on uneven surfaces, such as potholes, bumps, or speed bumps, the support base 1 can smoothly cross these obstacles, and the impact on the support base 1 will be fully dispersed. The vibration and impact force transmitted to the support base 1 and the ring main unit will be reduced, thereby improving the smoothness of movement. This is very beneficial for protecting precision equipment such as ring main units.

[0027] In some embodiments, multiple grooves 112 are spaced apart on the buffer platform. The cross-section of the grooves 112 is inverted T-shaped, and clamping blocks 113 are slidably disposed within the grooves 112.

[0028] In some embodiments, a fastening bolt 114 is rotatably mounted on the clamping block 113, and a T-nut 115 is threadedly connected to the lower end of the fastening bolt 114. The top of the T-nut 115 can slide into the wider portion of the slide groove 112. When the fastening bolt 114 is rotated, the T-nut 115 moves along the axis of the fastening bolt 114. Since the T-nut 115 is confined within the slide groove 112, its direction of movement is restricted, and it can only move along the axis of the fastening bolt 114, thereby producing a clamping or loosening effect, and thus achieving the fixing effect of the clamping block 113.

[0029] In some embodiments, the clamping block 113 may also be oscillatingly provided with an abutment block 117, and the clamping block 113 is provided with a ball head bolt 116, which is threadedly connected to the abutment block 117. By turning the ball head bolt 116, the oscillation angle of the abutment block 117 is adjusted so that the abutment block 117 abuts against the side wall of the ring main unit, thereby achieving clamping of the ring main unit.

[0030] In some embodiments, support rods 17 are threadedly connected to both sides of the support base 1. A handwheel 172 is fixedly connected to the upper end of the support rod 17, and a foot 171 is fixedly connected to the lower end of the support rod 17. When the ring main unit is moved to the designated position, the extension length of the support rod 17 can be adjusted by rotating the handwheel 172, so that the foot 171 contacts the ground, providing additional support and ensuring the stability of the base during long-term use.

[0031] In some embodiments, a damping rod 121 is fixedly connected to the support base 1, and a first spring 12 is fitted onto the outer wall of the damping rod 121. There are four damping rods 121, and they are slidably connected to the buffer platform 11. Without the damping rods 121, the structure connected by the first spring 12 or the second spring 15 will continuously sway and cannot return to a static equilibrium state. With the damping rods 121 installed, the structure can quickly return to a stable state when the first spring 12 or the second spring 15 is impacted. Since the structure of the damping rod 121 is well known to those skilled in the art, it is not described further in this specification.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
