Description

Technical Field

[0001] The utility model relates to the technical field of transformer box protection, in particular to an intelligent protection device for an intelligent power distribution terminal. Background Art

[0002] Substations on the roadsides of cities are often subject to various external threats, including collisions, fires, floods, etc. Among them, collisions are one of the most common threats. Vehicle accidents, construction, tree collapse, etc. may cause substations to be hit, leading to short circuits, fires, and other accidents.

[0003] In order to prevent the transformer box from being severely impacted, the following measures are usually taken:

[0004] 1. Install guardrails: Install guardrails around the transformer box to prevent accidental collisions by vehicles, pedestrians, etc.

[0005] 2. Change the structure of the transformer box: increase the thickness of the transformer box and select high-strength materials to enhance the impact resistance of the transformer box.

[0006] Existing guardrails are fixedly installed and usually have no buffer device to absorb energy after being hit, so they are easy to break. Changing the structure of the transformer box usually increases costs, and the thickened box affects heat dissipation.

[0007] Therefore, we urgently need to design a low-cost and impact-resistant intelligent protection device for distribution terminals. Utility Model Content

[0008] In order to solve the problems existing in the above-mentioned background technology, the utility model provides an intelligent protection device for distribution terminals with low cost and good anti-impact effect.

[0009] The technical solution is: an intelligent protection device for an intelligent power distribution terminal, comprising a box body, four protection units are arranged in a rectangular shape around the box body, the protection unit comprises a cross bar, a base, a railing, a reinforcing rib and a diagonal brace, the cross bar is hinged to the base through a rotating shaft, a long groove is provided on one side of the cross bar along the length direction, a buffer spring and a slider are provided in the long groove, a plurality of the railings are arranged at intervals on the upper side of the cross bar, the plurality of the railings are connected by reinforcing ribs, one end of the diagonal brace is hinged to the reinforcing rib, and the other end is hinged to the slider on the adjacent protection unit, and a short groove connected to the long groove on the adjacent protection unit is provided on the base;

[0010] The projection of the diagonal brace and the railing forms a certain angle, and the angle is not less than 10 degrees.

[0011] Furthermore, the diagonal brace is connected to the railing located at the outermost end of the reinforcing rib via a connecting rod, one end of the connecting rod is hinged to the diagonal brace, a vertical groove is provided on one side of the railing along the length direction, and the other end of the connecting rod is slidably matched with the vertical groove.

[0012] Furthermore, the maximum angle between the connecting rod and the diagonal brace is 90 degrees.

[0013] Furthermore, a rotating mechanism is included, which includes a rectangular disk and a circular ring rotatably arranged on the upper side of the rectangular disk, the protective unit is arranged on the circular ring, and the box body passes through the inner ring of the circular ring and is arranged on the rectangular disk.

[0014] Furthermore, a reflective strip is included, and the reflective strip is pasted on the reinforcing rib.

[0015] The beneficial effects of the utility model are:

[0016] 1. The cross bar of the utility model is hingedly connected to the base. When impacted by external force, the railing is tilted together with the cross bar, and the diagonal support rod drives the slider to slide along the long groove and squeeze the buffer spring. During this period, the buffer spring absorbs part of the impact kinetic energy. The diagonal support rod and the buffer spring can enhance the supporting strength of the stressed railing to prevent it from breaking. After the external force is removed, the device can automatically return to its original state under the action of the buffer spring. The device has a simple structure and good anti-impact ability.

[0017] 2. By setting connecting rods, the supporting strength of the diagonal braces on the railings can be enhanced.

DETAILED DESCRIPTION

[0026] 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.

[0027] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0028] like Figure 1-6As shown, an intelligent protection device for an intelligent power distribution terminal includes a box body 1, four rectangularly distributed protection units are arranged around the box body 1, and the four protection units are connected end to end in sequence to form a protection area. When the box body 1 is impacted from the outside, the protection unit can reduce the damage to the box body 1 caused by the impact, wherein the protection unit includes a cross bar 2, a base 3, a railing 4, a reinforcing rib 5 and a diagonal brace 6, the cross bar 2 and the base 3 are hinged by a rotating shaft, and a long groove 21 is provided on one side of the cross bar 2 along the length direction, and the long groove 21 A buffer spring 22 and a slider 61 are provided inside, and multiple railings 4 are arranged at intervals on the upper side of the crossbar 2. The multiple railings 4 are connected by reinforcing ribs 5. It should be noted that the spacing between adjacent railings 4 is not greater than 30 cm, preferably 10 cm. When a tree collapses, a smaller spacing can prevent it from being stuck between two railings 4. One end of the diagonal brace 6 is hinged to the reinforcing rib 5, and the other end is hinged to the slider 61 on the adjacent protection unit. The base 3 is provided with a short slot 31 connected to the long slot 21 on the adjacent protection unit. It should be particularly noted that the projection of the diagonal brace 6 and the railing 4 is at a certain angle, preferably not less than 10 degrees. Through testing, it is known that when the projection of the diagonal brace 6 and the railing 4 forms a certain angle greater than 10 degrees, the railing 4 is tilted by impact, and the opening smoothness of the diagonal brace 6 is enhanced. A too small angle is not conducive to the opening of the diagonal brace 6. In addition, the lower end of the diagonal brace 6 is placed in the short groove 31 in the conventional state, otherwise it will interfere with the adjacent protection unit and hinder its tilting. In order to strengthen the supporting strength of the diagonal brace 6 to the railing 4, a connecting rod 7 is also provided. For details, refer to Figure 5 , wherein one end of the connecting rod 7 is hinged to the diagonal brace 6, and the other end of the connecting rod 7 is connected to the adjacent railing 4 located at the outermost end of the reinforcing rib 5, and a vertical groove 41 is provided on one side of the railing 4 along the length direction, and the other end of the connecting rod 7 is slidably connected to the vertical groove 41. It should be noted that the maximum angle between the connecting rod 7 and the diagonal brace 6 is 90 degrees. And at the maximum angle, the supporting effect is best. When some broken trees, construction scaffolding, etc. collapse, they tilt on this device, and when hit, one of the front-supported railings 4 is squeezed and tilted, and receives the joint action of the diagonal brace 6, the connecting rod 7 and the buffer spring 22, which supports it and absorbs part of the impact kinetic energy, thereby reducing the damage to the box 1. When the external force is removed, the device can automatically return to its original state under the action of the buffer spring 22. The structure of the device is simple and the manufacturing cost is low.

[0029] In addition, the utility model also includes a rotating mechanism, which includes a rectangular disk 8 and a circular ring 81 rotatably arranged on the upper side of the rectangular disk 8 , the protection unit is arranged on the circular ring 81 , and the box body 1 passes through the inner circle of the circular ring 81 and is arranged on the rectangular disk 8 .

[0030] By providing the rotating mechanism, the lateral impact force of cars, electric vehicles, etc. on the utility model can be reduced. When impacted, the ring 81 and the guardrail 4 provided thereon rotate to change the direction of the impact on the guardrail 4, thereby reducing the impact.

[0031] like Figure 6 As shown, a reflective strip 9 is included, and the reflective strip 9 is pasted on the reinforcing rib 5 to warn passing vehicles and serve as a reminder.

[0032] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
