Description

Technical Field

[0001] The utility model belongs to the technical field of electric power devices, and in particular relates to a transport structure for an outdoor ring network box. Background Art

[0002] Box-type substations are essential equipment for urban power grid construction and renovation in my country. Ring main units (RMUs) are electrical equipment consisting of a set of high-voltage switchgear mounted in a thick steel metal cabinet or assembled into a spaced-apart ring main unit. Key components of these units are high-voltage load switches and circuit breakers. These units offer advantages such as simple structure, compact size, low cost, and the ability to improve power supply parameters, functionality, and safety.

[0003] When the existing ring network box-type substation is in use, it needs to be moved to the required installation location by a crane. Although it is small in size, it is relatively troublesome to manually move it after it is placed on the ground, resulting in low flexibility of the device.

[0004] The Chinese utility model patent with the utility model patent announcement number CN218334970U and the announcement date of January 17, 2023, discloses a ring network box-type substation that is easy to hoist. The structure includes a box body, a slot, a U-shaped slot, a mounting hole, a through hole, a top cover, a perforation, a slot, an insert, a U-shaped plate, a first threaded hole, a fixing bolt, a clamping ring, a round hole, a hanging column, a lifting ring, a second threaded hole and a fastening screw.

[0005] The general structural principle of the ring network box-type substation in this utility model patent is as follows: a top cover is provided above the box body, and through holes are provided on the upper surface of the top cover near the four corners, and hanging columns are provided in the through holes, and hanging rings are provided on the top of the hanging columns. Second threaded holes are provided on the outer wall of the circumference of the hanging columns near the bottom, and fastening screws are provided in the second threaded holes. Slots are symmetrically provided on the top cover, and snap rings are provided in the slots. Mounting holes are provided on the upper surface of the box body corresponding to the hanging columns, and through holes connected to the mounting holes are provided on both sides of the box body. U-shaped grooves are provided on the box body corresponding to the snap rings, and U-shaped plates are provided in the U-shaped grooves.

[0006] However, the ring network box-type substation which is easy to hoist has at least the following deficiencies in actual use, in other words, these are the technical problems to be solved by the present utility model.

[0007] During the lifting and moving process, the lack of cushioning at the bottom of the box in contact with the ground may cause excessive vibration or displacement of internal equipment.

[0008] Therefore, in summary, there is an urgent need for a new type of transport structure for outdoor ring network boxes that has a sufficient buffering effect. Utility Model Content

[0009] The utility model provides a transport structure for an outdoor ring network box, which can be achieved by arranging a buffer leg unit: the buffer leg unit is used to be installed on the box body, and during the lifting process, the buffer leg unit arranged on the box body is naturally extended. When the box body is a certain distance from the ground, the buffer leg unit first contacts the ground, which can remind the operator that the box body is close to the ground. During the fall, the buffer leg unit has a certain degree of resistance, thereby slowing down the descent speed of the box body, effectively reducing shock, and ensuring the safety of the equipment in the box body. Finally, the buffer leg unit fits with the ground, further supports and stabilizes the box body, and improves the structural stability.

[0010] The technical solution adopted by the present invention to solve the above problems is: a transport structure for an outdoor ring network box, comprising a buffer support unit arranged on the box body and used to slow down the descent speed of the box body by retracting.

[0011] A further preferred technical solution is that the buffer support foot unit includes a sleeve arranged on the box body, an upper end plate arranged on the sleeve and used to connect the top cover, a support rod inserted into the sleeve, an upper end slider arranged at the upper end of the support rod and used to fit the inner wall of the sleeve, and a lower end limit ring arranged at the bottom end of the sleeve and used to sleeve on the support rod.

[0012] A further preferred technical solution is that the buffer foot unit further includes a buffer spring disposed in the sleeve and used to connect to the upper end slider.

[0013] A further preferred technical solution is that: the buffer foot unit further includes a support pad provided at the bottom end of the support rod.

[0014] A further preferred technical solution is that the buffer foot unit further includes a connecting screw arranged on the upper end plate, and a fastening nut arranged on the connecting screw and used to clamp the top cover.

[0015] A further preferred technical solution is that the buffer foot unit further includes a connecting hole plate arranged on the upper end plate, on which the connecting screw is installed and used to connect to the top cover.

[0016] A further preferred technical solution is that: the number of the upper end plates is set to 4.

[0017] A further preferred technical solution is that: the buffer foot unit further includes a connecting transverse plate arranged between two adjacent upper end plates and / or connecting hole plates.

[0018] A further preferred technical solution is that the buffer foot unit further includes an anti-slip layer arranged at the bottom of the support pad.

[0019] A further preferred technical solution is that the cross section of the upper end plate is a quarter circle. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0029] As attached Figure 1-4 As shown, a transport structure for an outdoor ring network box includes a buffer support unit 1 arranged on the box body a and used to slow down the descending speed of the box body a by retracting.

[0030] In this embodiment, the box a is usually transported by machine lifting, and a lifting ring is usually provided on the upper end of the top cover b or the side wall of the box a for easy transportation. However, during the lifting process, it is difficult for the operator to observe the actual distance between the box a and the ground, and it is difficult to control the speed during transportation. As a result, when the box a is close to the ground, the box a is placed on the ground at a faster speed and with a heavier force, causing damage to the box a or displacement of the electrical equipment in the box a. The buffer leg unit 1 can solve this problem well. On the one hand, the buffer leg unit 1 is provided on the side wall of the box a and is a retractable structure. When the box a is lifted, the buffer leg unit 1 is extended by gravity and extends beyond the bottom of the box a. During transportation, the buffer leg unit 1 contacts the ground before the box a. After contact, the operator can clearly feel that the box a is closer to the ground, which can remind the operator to consciously slow down the falling speed. At the same time, the buffer leg unit 1 can also slow down the falling speed of the box a to a certain extent, preventing the box a from being bumped and bumped when falling, thereby further protecting the box a. On the other hand, after the box a is firmly in contact with the ground, the buffer leg unit 1 also contacts the ground, which can support the box a and can also structurally limit the telescopic distance of the buffer leg unit 1, so that the buffer leg unit 1 can meet the installation and placement of the box a under different terrain conditions.

[0031] The buffer support unit 1 includes a sleeve 101 arranged on the box body a, an upper end plate 102 arranged on the sleeve 101 and used to connect to the top cover b, a support rod 103 inserted into the sleeve 101, an upper end slider 104 arranged at the upper end of the support rod 103 and used to fit the inner wall of the sleeve 101, and a lower end limiting ring 105 arranged at the bottom end of the sleeve 101 and used to sleeve the support rod 103.

[0032] In this embodiment, the sleeve 101 is arranged on the side wall of the box a, and the bottom of the sleeve 101 is consistent with the bottom of the box a as much as possible, so as to facilitate supporting the box a. The upper end plate 102 is used to connect the sleeve 101 with the top cover b, and the support rod 103 is inserted into the sleeve 101 through the upper end slider 104. In order to ensure that the support rod 103 can slow down the descending speed of the box a to a certain extent after contacting the ground, it can be achieved by increasing the friction or sealing between the upper end slider 104 and the sleeve 101. The function of the lower end limit ring 105 is to resist the upper end slider 104 to prevent the support rod 103 from separating from the sleeve 101. The difficulty of wiping sweat of the support rod 103 can be set according to actual needs.

[0033] The buffer foot unit 1 further includes a buffer spring 106 disposed in the sleeve 101 and used to connect to the upper end slider 104 .

[0034] In this embodiment, the function of the buffer spring 106 is to further increase the retraction speed of the support rod 103. When the friction between the upper end slider 104 and the sleeve 101 is insufficient, the buffer spring 106 can play a supplementary deceleration effect. When the box a is lifted, the buffer support leg unit 1 is subjected to the tension of the buffer spring 106 and the expansion and contraction range is reduced.

[0035] The buffer foot unit 1 further includes a support pad 107 disposed at the bottom end of the support rod 103 .

[0036] In this embodiment, the support block 107 functions to effectively support the box a. The support block 107 can be at the same level as the bottom of the box a, or can lift up the box a.

[0037] The buffer foot unit 1 further includes a connecting screw 108 provided on the upper end plate 102 and a fastening nut 109 provided on the connecting screw 108 and used for clamping the top cover b.

[0038] In this embodiment, the connecting screw 108 and the fastening nut 109 function to strengthen the connection strength of the upper end plate 102 .

[0039] The buffer foot unit 1 further includes a connection hole plate 110 disposed on the upper end plate 102 , on which the connection screw 108 is installed and used to connect to the top cover b.

[0040] In this embodiment, the connecting hole plate 110 can detachably connect the upper end plate 102 to the top cover b through the connecting screw 108 and the fastening nut 109, so that the transport structure used for the outdoor ring network box can be recycled and can adapt to various transport requirements of the box a, and has strong practicality and flexibility.

[0041] The number of the upper end plates 102 is four.

[0042] In this embodiment, the four upper end plates 102 are arranged on both sides of the box body a to better support the box body a.

[0043] The buffer foot unit 1 further includes a connecting transverse plate 111 disposed between two adjacent upper end plates 102 and / or connecting hole plates 110 .

[0044] In this embodiment, the connecting cross plate 111 connects the adjacent upper end plates 102 and / or connecting hole plates 110 to increase the integrity and connection strength of the structure, while ensuring that all the sleeves 101 and the support rods 103 are at the same level, and the installation stability of the box a.

[0045] The buffer foot unit 1 further includes an anti-slip layer 112 disposed at the bottom of the support block 107 .

[0046] In this embodiment, the anti-slip layer 112 serves to further protect the support block 107 and increase the friction strength between the support block 107 and the ground.

[0047] The cross section of the upper end plate 102 is a quarter circle.

[0048] In this embodiment, the upper end plate 102 can be rectangular, but in order to increase the overall aesthetics and reduce the risk of the buffer foot unit 1 colliding with people close to the box a, the upper end plate 102 is set to a quarter circle, and the outward protruding end of the upper end plate 102 is an arc shape.

[0049] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications are possible within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. These modifications are non-inventive and are protected by patent law as long as they fall within the scope of the claims of the present invention.
