Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformer substations, in particular to a modular skid-mounted transformer substation. Background Art
[0002] Skid-mounted substations have been widely used in construction and engineering sites such as oil fields and construction sites. They are deeply favored by customers due to their movable characteristics. Currently, most skid-mounted substations on the market are 10KV / 0.4KV with a capacity of 2500KVA. Since some construction sites only have a voltage level of 35KV, the current conventional method of use is to build a substation on site, first convert the 35KV voltage into 10KV, and then use a conventional box-type substation.
[0003] In the existing technology, a group of metal boxes are installed, the substation is placed inside the box, and a ventilation net is opened on one side of the box. When the substation is working, it is in contact with the outside air through the ventilation net, so as to cool it down. This operation is convenient and quick. However, the box is always placed outdoors. When the ventilation net is in contact with the outside, rain will be affected by the wind and float into the inside of the box. Moreover, the outer shell is mostly made of metal. If the internal equipment of the substation leaks electricity, the outer shell will be charged, which will be dangerous if people touch it. At the same time, in rainy weather, water is easy to enter the bottom, causing the internal equipment to be affected.
[0004] Therefore, it is particularly important to improve the existing modular skid-mounted substation and design a new modular skid-mounted substation to solve the above technical defects and improve the practicality of the overall modular skid-mounted substation. Utility Model Content
[0005] The purpose of the utility model is to provide a modular skid-mounted substation to solve the problems raised in the above background technology.

[0008] The opening and closing assembly is used to quickly complete the shielding work of the ventilation net.
[0009] As a preferred solution of the utility model, the opening and closing assembly includes a chain, a gear, a linkage rod, a connecting rod slider and a barrier door. The chain is installed on the inner side of the box and is located on the back of the ventilation net. The gears are symmetrically installed inside the chain. The linkage rod is installed on the side of the chain close to the ventilation net. The connecting rod is installed at the bottom of the linkage rod, the slider is installed at the bottom of the connecting rod, and the barrier door is installed at the bottom of the slider.

[0011] As a preferred solution of the utility model, connecting blocks are installed at the four corners of the top of the box body, waist grooves are opened on the top and outside of the connecting block, and the interior of the connecting block is designed as an open structure.
[0012] As a preferred solution of the utility model, a reinforcing strip is installed on the top of the box body, a bottom plate is installed on the bottom of the box body, and a through groove is opened inside the bottom plate.
[0013] As a preferred solution of the utility model, the four supporting legs at the bottom of the supporting plate have a toothed plate installed inside the supporting legs, a rotating wheel installed outside the toothed plate, a handle installed on the side of the rotating wheel away from the toothed plate, and the handle extends to the outside of the supporting legs.
[0014] As a preferred solution of the utility model, a locking rod is installed below the rotating wheel, the bottom end of the locking rod is connected to the inside of the supporting leg by a rotating connection, a spring is installed at the bottom of the locking rod, and hook rings are installed around the top of the substation.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] In the utility model, the inside of the box is brought into contact with the outside air through the ventilation net, so that the inside of the box is cooled down. When heavy rain and flood weather occurs, the gear is rotated, so that the chain is driven to rotate around the gear through the rotation of the gear, so that the two sets of linkage rods are brought closer to each other, thereby driving the connecting rod and the slider to be brought closer to each other, so that the slider slides inside the slide rail, and the slider and the barrier door are connected through the slide groove. At the same time, the slider is limited by the slide rail to make it move along a straight line. The shielding area of the back of the ventilation net is changed by the mutual movement distance of the barrier door, so that wind and rain can effectively enter the inside of the box. When heavy rain occurs and water accumulates at the bottom end of the inner side of the box, in order to prevent the substation from contacting the accumulated water, the handle is pressed to rotate the wheel to contact the tooth plate, so that the tooth plate is lifted upward, and the handle is repeatedly pressed down.

DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0024] Example:
[0025] See also Figure 1-Figure 5 , the utility model provides a technical solution:
[0026] A modular skid-mounted substation includes a box body 1, a support plate 2 is installed inside the box body 1, a substation 3 is installed on the top of the support plate 2, a ventilation net 4 is installed on the left side of the box body 1, and an opening and closing component 5 is installed inside the ventilation net 4;
[0027] The opening and closing assembly 5 is used to quickly complete the shielding work of the ventilation net 4.
[0028] For further information, see Figure 3 and Figure 4 In this embodiment, the opening and closing assembly 5 includes a chain 501, a gear 502, a linkage rod 503, a connecting rod 504, a slider 505 and a blocking door 506. The chain 501 is installed on the inner side of the box 1 and is located on the back of the ventilation net 4. The gear 502 is symmetrically installed inside the chain 501. The linkage rod 503 is installed on the side of the chain 501 close to the ventilation net 4. The connecting rod 504 is installed at the bottom of the linkage rod 503. The slider 505 is installed at the bottom of the connecting rod 504, and the blocking door 506 is installed at the bottom of the slider 505. After the substation 2 is used, the internal mechanical work generates Heat is transmitted through the ventilation net 4 so that the inside of the box 1 is in contact with the outside air, thereby cooling the inside of the box 1. When there is heavy rain and wind, the gear 502 is rotated, and the chain 501 is driven to rotate around the gear 502 through the rotation of the gear 502, so that the two sets of linkage rods 503 are brought close to each other, thereby driving the connecting rod 504 and the slider 505 to approach each other, thereby achieving the mutual approach of the blocking door 506. The shielding area on the back of the ventilation net 4 is changed by the mutual moving distance of the blocking door 506, so that wind and rain can effectively enter the interior of the box 1.
[0029] Among them, see Figure 3 and Figure 4 In this embodiment, a slide rail 507 is installed on the outside of the slider 505, and a slide groove 508 is opened at the bottom end of the inner side of the slide rail 507. The blocking door 506 is connected to the slider 505 through the slide groove 508. When the linkage rods 503 are close to each other, the slider 505 slides inside the slide rail 507, and the slider 505 and the blocking door 506 are connected through the slide groove 508. At the same time, the slider 505 is limited by the slide rail 507 to make it move in a straight line, which greatly enhances the practicality.
[0030] Second, see Figure 1 and Figure 3In this embodiment, connecting blocks 6 are installed at the four corners of the top of the box body 1. Waist grooves are opened on the top and outside of the connecting block 6. The interior of the connecting block 6 is designed in an open structure. Through the design of the connecting block 6 and the waist groove, when the box body 1 is transported, the hook of the crane is passed through the waist groove with the help of a crane, so that the box body 1 is lifted as a whole, thereby quickly completing the transportation work.
[0031] Furthermore, please see Figure 1 and Figure 3 In this embodiment, a reinforcing strip 7 is installed on the top of the box body 1, and a bottom plate is installed on the bottom of the box body 1. A through groove is opened inside the bottom plate. The reinforcing strip 7 effectively strengthens the impact resistance of the box body 1, so that the service life is greatly extended. When the box body 1 is transported to the designated location and needs to be unloaded from the carriage, the front fork of the forklift is inserted into the through groove to complete the unloading work more quickly.
[0032] For further information, see Figure 2 and Figure 5 In this embodiment, there are four supporting legs 8 at the bottom of the supporting plate 2, and a tooth plate 9 is installed inside the supporting legs 8, and a rotating wheel 10 is installed outside the tooth plate 9. A handle 11 is installed on the side of the rotating wheel 10 away from the tooth plate 9, and the handle 11 extends to the outside of the supporting leg 8. When heavy rain occurs and water accumulates at the bottom inner side of the box body 1, in order to prevent the substation 3 from contacting the accumulated water, the handle 11 is pressed so that the rotating wheel 10 contacts the tooth plate 9, thereby realizing the upward lifting of the tooth plate 9, and repeatedly pressing the handle 11 downward to realize the rising work of the substation 3.
[0033] For further information, see Figure 2 and Figure 5 In this embodiment, a locking rod 12 is installed below the rotating wheel 10, and the bottom end of the locking rod 12 is connected to the inside of the supporting leg 8 in a rotating manner. A spring 13 is installed at the bottom of the locking rod 12, and hook rings 14 are installed around the top of the substation 3. The tooth plate 9 is raised to limit the locking rod 12 to the tooth plate 9. When the fixation needs to be released, the locking rod 12 is turned to drive the bottom end of the locking rod 12 and the supporting leg 8 to rotate, thereby squeezing the spring 13, so that the locking rod 12 leaves the tooth plate 9, and at the same time, it is connected to the hook ring 14 with the help of the hanger and lifted upward, and the upper and lower parts exert force at the same time to complete the rising and lowering work.
[0034] In this embodiment, the implementation scenario is specifically as follows: after the substation 2 is used, heat is generated by mechanical work inside, and the inside of the box 1 is brought into contact with the outside air through the ventilation net 4, so as to cool the inside of the box 1. When there is heavy rain and rain, the gear 502 is rotated, so that the chain 501 is driven to rotate around the gear 502 through the rotation of the gear 502, so that the two sets of linkage rods 503 are brought close to each other, thereby driving the connecting rod 504 and the slider 505 to be close to each other, so that the slider 505 slides inside the slide rail 507, and the slider 505 and the barrier door 506 are realized through the slide groove 508. The sliding block 505 is connected, and the sliding rail 507 is used to limit the sliding block 505 so that it moves in a straight line. The mutual moving distance of the blocking door 506 is used to change the shielding area on the back of the ventilation net 4, so that wind and rain can effectively enter the interior of the box body 1. When heavy rain occurs and water accumulates at the bottom inner side of the box body 1, the substation 3 is prevented from contacting the accumulated water. By pressing the handle 11, the rotating wheel 10 is in contact with the tooth plate 9, so that the tooth plate 9 is lifted upward, and the handle 11 is repeatedly pressed down. At the same time, it is connected with the hook ring 14 with the help of the hanger and lifted upward. The upper and lower parts exert force at the same time to complete the rising and lowering work.
