Description

Technical Field

[0001] This utility model relates to the field of power supply facilities, specifically a ring main unit. Background Technology

[0002] The ring main unit is equipped with a ring main unit, which forms a closed loop through the ring power distribution network and power distribution trunk line, playing the role of intelligent power distribution and intelligent power control, and ensuring the stability of daily power supply.

[0003] During the installation of ring main units, it is necessary to confirm whether the location where they will be used has a concrete foundation (i.e., a protruding concrete installation platform). Installing the ring main unit on a concrete foundation will prevent the bottom of the ring main unit from being soaked by rainwater. If there is no concrete foundation on site or the concrete foundation is too low, the ring main unit cannot be installed and used directly. In this case, multiple support legs must be added to the bottom of the ring main unit using bolts to replace the concrete foundation. When adding support legs to the bottom of the ring main unit, each support leg must be fixed to the ring main unit with at least four bolts. Given the large number of support legs, it is not feasible to quickly assemble the support legs on-site if it is done temporarily (by lifting the ring main unit with a crane or forklift).

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example: Please refer to Figures 1-11 The ring mesh box shown in the figure includes: a ring mesh box 1 and a bottom support circumference 2 fixed to the bottom of the ring mesh box 1. The inner side wall of the bottom support circumference 2 is provided with a number of storage slots 3 distributed at equal intervals. Each storage slot 3 is provided with a support leg component inside, and an adjustment component is also provided between the support leg component and each storage slot 3.

[0035] The support legs are used to separate the ring mesh box 1 and the bottom support perimeter 2 from the ground;

[0036] The adjustment component is used to control whether the support leg component is in the retracted or supported state.

[0037] The support leg component includes a pin 7 that is laterally rotatable inside the storage groove 3, a curved rod 8 that is fixedly sleeved on the outer surface of the pin 7, and a support leg 4 that is fixedly installed at the other end of the curved rod 8.

[0038] When in the storage state, the support leg 4 retracts into the storage slot 3, and the lower end of the bottom support edge 2 directly contacts the ground;

[0039] In the supported state, the support leg 4 moves to the bottom of the bottom support edge 2, and the bottom of the bottom support edge 2 is in contact with the end face of the support leg 4. The support leg 4 is supported between the bottom support edge 2 and the bottom surface. The rotation of the pin 7, through the crank 8, causes the support leg 4 to run synchronously. The maximum downward swing of the pin 4 ensures that the end face of the support leg 4 is in contact with the bottom surface of the bottom support edge 2, thus ensuring that the support leg 4 effectively supports the bottom support edge 2.

[0040] The adjusting components include a worm gear 9 fixedly sleeved on the outer surface of the pin 7, and a worm 10 rotatably fitted inside the receiving groove 3, which meshes with the worm gear 9. The axis of the worm 10 is perpendicular to the axis of the pin 7. The receiving groove 3 extends from the end of the worm 10 away from the center of the bottom support edge 2. By rotating the receiving groove 3 and meshing the worm 10 and the worm gear 9, the pin 7 can be adjusted in position along with the support foot 4.

[0041] The end of the worm gear 10 extending out of the storage groove 3 is provided with a hexagonal groove 11, which makes it convenient for workers to rotate the worm gear 10 using a hexagonal wrench or an electric hand.

[0042] Each support leg 4 is fixedly provided with a bolt fixing block 17 on the end face away from the curved rod 8, and the bolt fixing block 17 has a central hole inside. By passing the bolt through the central hole, the bolt fixing block 17 and the support leg 4 can be fixed to the cement ground.

[0043] Two symmetrically distributed mounting plates 12 are fixedly installed at the end of the support leg 4 away from the curved rod 8, and bolt fixing blocks 17 are distributed between the two mounting plates 12. When the support leg 4 is in the supported state, a protective mesh plate 5 is slidably inserted between two adjacent mounting plates 12. The protective mesh plate 5 is used to protect the gap between the bottom support edge 2 and the ground. When the ring main unit inside the ring main unit 1 is connected or distributed, the cable will pass through the bottom of the ring main unit 1, and the cable will be protected by the protective mesh plate 5. The function is to prevent small animals from crawling into the bottom or inside of the ring mesh box 1 and damaging the cables. The protective mesh plate 5 is in the shape of a straight plate or an L-shape. The straight protective mesh plate 5 is installed on the straight edge of the bottom support rim 2, and the L-shaped protective mesh plate 5 is installed at the corner of the bottom support rim 2. The end face of the mounting plate 12 is provided with a chamfered part 16, and the bevel of the chamfered part 16 faces the support leg 4. The chamfered part 16 guides the workers to easily insert the protective mesh plate 5 between the mounting plate 12 and the support leg 4.

[0044] Each support leg 4 has a perforated groove 13 on one end face near each mounting plate 12. Inside the support leg 4, a frame block 14 is fixedly installed on one end face near the perforated groove 13. Several metal clips 15 are fixedly installed on one end of the frame block 14 near the mounting plate 12, arranged in a straight line at equal intervals. The bottom of the metal clips 15 is raised, and the raised part extends downward to the perforated groove 13. Each end of the protective mesh plate 5 near the support leg 4 has a set of triangular grooves 6. There are several triangular grooves 6 in each set, arranged in a straight line at equal intervals. The bottom of the metal clips 15 and the triangular grooves 6 are movably snapped together. Through the cooperation of the raised part of the metal clips 15 and the triangular grooves 6, the protective mesh plate 5 will not fall back after it is installed between the mounting plate 12 and the support leg 4.

[0045] The metal clip 15 is made of an elastic metal sheet. When the protective mesh plate 5 is inserted between the support leg 4 and the mounting plate 12, it can press the raised part. After the raised part rebounds, it will restrict the triangular groove 6, preventing the protective mesh plate 5 from retracting.

[0046] The triangular groove 6 is triangular in shape, with the lower end of the triangular groove 6 being a horizontal plane and the other end being an inclined plane. When the protective mesh plate 5 is pulled upward, the lower end of the raised part of the metal clip 15 will abut against the horizontal end face of the triangular groove 6, thereby preventing the protective mesh plate 5 from moving upward.

[0047] The width of the protective mesh panel 5 is greater than the length of the support leg 4, thus completely covering the gap between the bottom support edge 2 and the bottom surface.

[0048] Working principle: After transporting ring main unit 1 to the construction location, if the cement foundation at the installation site meets the standards, ring main unit 1 can be directly placed on the cement foundation at the site, as if... Figure 4 The display status in the middle;

[0049] If there is no cement foundation at the installation site, or the cement foundation is not up to standard, the support leg 4 needs to be moved to the bottom of the bottom support edge 2 before the ring network box 1 is moved to the installation position. When the ring network box 1 is in the hoisting state or being lifted by a forklift, the workers use an electric hand auger to rotate the worm gear 10 through the hexagonal groove 11. During the rotation, the worm gear 10 can deflect the worm wheel 9 and the pin 7, thereby moving the support leg 4 from the storage groove 3 to the bottom of the bottom support edge 2. This allows the support leg 4 to be quickly installed at the bottom of the bottom support edge 2, and then the ring network box 1 can be placed in the installation position.

[0050] The above method can improve the applicability of the ring network box 1. It can not only be directly installed on a cement foundation, but also the bottom support foot 4 can be quickly added to the bottom of the bottom support edge 2 and directly installed on the cement ground. Compared with the existing technology of installing the support foot one by one by bolting, the method in this solution is more convenient and efficient.

[0051] After the ring network box 1 is installed using the support legs 4, it can be fixed to the cement ground by the bolt fixing blocks 17 and the center hole, thus ensuring the stability of the ring network box 1. At the same time, the workers also need to insert the protective mesh plate 5 between the corresponding two mounting buckles 12. During the insertion process, the metal clip 15 is used to restrict the triangular groove 6, ensuring that the protective mesh plate 5 cannot be removed at will. The convenient installation method also ensures the stability of the protective mesh plate 5. After the protective mesh plate 5 is installed, it can prevent small animals from crawling into the bottom of the ring network box 1 and causing damage to the internal power distribution cables without affecting the heat dissipation at the bottom of the ring network box 1.
