Description

Technical Field

[0001] This utility model relates to the field of substation technology, and more specifically, to a high- and low-voltage prefabricated substation with good protection performance. Background Technology

[0002] Prefabricated substations are steel structure boxes that organically combine the functions of transformer voltage reduction and low-voltage power distribution. They can be used as ring network or terminal-type power distribution devices. They are widely used in residential areas, industrial and mining enterprises, hotels, hospitals, shopping malls, airports, parks, railways, and other outdoor locations.

[0003] Existing technologies disclose some patent documents for prefabricated high and low voltage substations with good protection performance. Chinese patent application number CN202321403516.1 discloses a prefabricated high and low voltage substation with good protection performance, including a box body. Fixing blocks are provided on the outer side of the four corners of the box body. The cross-section of the fixing blocks is L-shaped. Two slots are vertically opened on the top of the fixing blocks. Limiting slots are vertically opened at both ends of the fixing blocks. A barrier net and a collision protection plate are provided between two adjacent fixing blocks. Insert rods are provided in the slots. The two ends of the barrier net are connected to the two insert rods respectively. The first level of obstruction is achieved through the barrier net, which absorbs some of the kinetic energy of objects. If a pedestrian or vehicle collides with the barrier net, it can protect them and reduce the damage they suffer. The second level of obstruction is achieved through rigid crash barriers, which prevent damage to the enclosure and avoid the need for maintenance. If the barrier net or crash barrier is damaged, the insert rods and mounting rods can be removed directly to replace the barrier net. The crash barriers and rotating plates can be replaced directly by pulling out the reinforcing posts, making the replacement very convenient and quick.

[0004] In the aforementioned patent, the protective plate is fixed by plugging, which has poor stability and its protective effect will be reduced when it is impacted. Therefore, we propose a high and low voltage prefabricated substation with good protective performance. Utility Model Content

[0040] In one specific embodiment, each fixing mechanism includes a snap-fit ​​component and a fixing component, both of which are disposed on the base 1 and are connected to each other.

[0041] In this embodiment, each fixing mechanism includes a snap-fit ​​component and a fixing component, both of which are disposed on the base 1 and are connected to each other.

[0042] In one specific embodiment, the snap-fit ​​assembly includes a positioning groove 5, a crossbar 7, a mounting groove 9, and a positioning cylinder 14. There are two positioning grooves 5, which are respectively opened on the inner side of the two columns 4. The crossbar 7 is movably inserted into the two columns 4 and is located on the vibration damping and protective plate 6. The mounting groove 9 is opened in the crossbar 7. There are two positioning cylinders 14, which are both set in the mounting groove 9 and are movably inserted into the two positioning grooves 5.

[0043] In this embodiment, the positioning groove 5 is opened to facilitate insertion with the positioning cylinder 14, the crossbar 7 is opened to facilitate snapping with the vibration damping and protection plate 6, the mounting groove 9 is opened to facilitate accommodating the fixing components, and the positioning cylinder 14 is opened to facilitate snapping with the positioning groove 5. The crossbar 7 is fixed by snapping with the positioning cylinder 14 and the positioning groove 5, thereby fixing the vibration damping and protection plate 6 by the crossbar 7.

[0044] In one specific embodiment, the fixing assembly includes a support 10, a bidirectional lead screw 11, a lead screw nut 12, and a sliding plate 13. Two supports 10, two lead screw nuts 12, and two sliding plates 13 are provided. The two supports 10 are fixedly connected to the mounting groove 9. The bidirectional lead screw 11 is rotatably connected to the two supports 10 and moves through the middle of the crossbar 7. The two lead screw nuts 12 are threadedly connected to the left and right sides of the bidirectional lead screw 11, respectively. The two sliding plates 13 are fixedly connected to the surfaces of the two lead screw nuts 12, and the two sliding plates 13 are slidably connected to the mounting groove 9. The two sliding plates 13 are fixedly connected to the two positioning cylinders 14, and the two positioning cylinders 14 are respectively sleeved on the left and right sides of the bidirectional lead screw 11.

[0045] In this embodiment, the support 10 is for easy rotational connection of the bidirectional lead screw 11. The rotation of the throttle 15 drives the bidirectional lead screw 11 to rotate. The rotation of the bidirectional lead screw 11 causes the two lead nuts 12 to move inward or outward at the same time. When the bidirectional lead screw 11 reverses, the two lead nuts 12 move outward at the same time. The movement of the lead nuts 12 drives the slide plate 13 to move outward. The movement of the slide plate 13 drives the positioning cylinder 14 to move outward.

[0046] Specifically, a throttle 15 is fixedly connected to the middle of each of the four bidirectional lead screws 11.

[0050] Specifically, sloping drainage holes 2 are provided around all four sides of the base 1.

[0051] In this embodiment, inclined drainage holes 2 are provided around the base 1. The inclined drainage holes 2 facilitate the drainage of water accumulated on the base 1, thereby preventing water accumulation.

[0052] The working principle or process of the high and low voltage prefabricated substation with good protection performance provided in this embodiment is as follows: When it is necessary to fix the vibration damping plate 6, first insert the vibration damping plate 6 between the two columns 4, and then insert the crossbar 7 between the two columns 4, with the crossbar 7 located on the vibration damping plate 6. At this time, turn the handle 15, and the rotation of the handle 15 drives the double-acting screw 11 to rotate. The rotation of the double-acting screw 11 causes the two screw nuts 12 to move inward or outward at the same time. When the double-acting screw 11 reverses, the two screw nuts 12 move outward at the same time. The movement of the screw nuts 12 drives the sliding plate 13 to move outward. The movement of the sliding plate 13 drives the positioning cylinder 14 to move outward. When the positioning cylinder 14 moves outward to be inserted into the positioning groove 5, the handle 15 can be stopped. At this time, the crossbar 7 can be fixed by the insertion of the positioning cylinder 14 and the positioning groove 5. The vibration damping plate 6 is installed and fixed by the crossbar 7.
