[0024] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0027] As described in the background art, a cascade-type rigid telescopic fence is inconvenient to carry, the assembly process is too complicated, the operation is tedious, the disassembly and assembly of the fence takes a long time, and there are certain limitations in its use.

[0028] In order to solve this technical problem, the utility model provides an automatic fence device, which is applied to power maintenance enclosures.

[0029] For details, please refer to Figure 1-3 The automatic fence device specifically includes: a cart 14, two arc-shaped fences 1 and a driving assembly for synchronously and unidirectionally driving the two arc-shaped fences 1. A slide rail 2 is provided at the bottom of the arc-shaped fence 1, and two concentric slides 3 are provided on the cart 14. The slide rails 2 on the two arc-shaped fences 1 are respectively slidably installed in the two slides 3. The driving assembly includes a driving wheel 4 rotatably installed between the two slides 3 and a driving motor 5 fixedly installed at the bottom of the cart 14 and providing power for the rotation of the driving wheel 4; the slide rails 2 on the two arc-shaped fences 1 are respectively in close contact with both sides of the driving wheel 4; further, the arc-shaped fence 1 is preferably a semicircular fence; when there is no telescopic fence, the two arc-shaped fences 1 and the self-closing enclosure form a circular fence.

[0030] A telescopic fence is installed on the arc-shaped fence 1 away from the cart 14; the arc-shaped fence 1 is preferably a 1 / 4 circle arc-shaped fence 1.

[0031] For details, please refer to Figure 3The telescopic handicap frame adopts a scissors-type pole frame, which includes two vertical supports 6 and a scissors-type pole frame 7. The bottom of the two ends of the scissors-type pole frame 7 is hinged to one side of the bottom of the two vertical supports 6 respectively, and the top of the two ends of the scissors-type pole frame 7 is rotatably installed with rollers 8. The vertical supports 6 are provided with rolling grooves 9 that allow the rollers 8 to roll up and down. A group of vertical supports 6 adjacent to the arc-shaped handicap frame 1 is installed with a linear feed drive 10 that provides power for the rollers 8 to roll up and down; further, the linear feed drive 10 is preferably an electric cylinder, one end of the electric cylinder is hinged to the vertical rod, and the other end of the electric cylinder is rotatably connected to the roller 8; the linear feed drive 10 can also adopt a linear motor or other equivalent parts with a linear drive effect.

[0032] For details, please refer to Figure 4 A set of vertical supports 6 adjacent to the scissor-type pole frame is rotatably connected to the arc-shaped barrier frame 1, so as to realize the extension of the scissor-type pole frame in multiple directions and improve the diversity of the enclosure shape.

[0033] The telescopic fence can increase the enclosure range of the fence; by starting the linear feed driver 10, the roller 8 moves down along the rolling groove 9, so that the scissor rod group 7 is extended from the retracted state to the extended state, and the construction site can be blocked in a large range when in use; when not in use, the scissor rod group 7 is retracted, which effectively reduces the volume of the scissor rod group 7. At the same time, the arc-shaped fence 1 can be made of 1 / 4 circle. When not in use, that is, the arc-shaped fence 1 is in a retracted state, the extension length of the arc-shaped fence 1 to both sides on the trolley 14 can be effectively reduced, thereby reducing the volume of the entire fence device and further improving the convenience of movement; the two telescopic fences can be connected to the wall at the construction site such as Figure 1 The three-sided enclosure can also be carried out as shown. Figure 4 Closed enclosure method.

[0034] Specifically, universal wheels 11 are installed at the bottom of the curved hurdle frame 1 and at the bottom of a group of vertical supports 6 on the scissors-type pole frame away from the curved hurdle frame 1; the universal wheels 11 can effectively support the bottom of the curved hurdle frame 1 and the scissors-type pole frame, thereby improving the stability of the curved hurdle frame 1 and the scissors-type pole frame during movement.

[0035] For details, please refer to Figure 2 or Figure 5 ; The arc-shaped fence 1 is provided with a limit block 12 near the driving wheel 4; when the arc-shaped fence 1 extends outward from the cart 14, the limit block 12 can limit the maximum distance of the arc-shaped fence 1 extending outward to prevent the slide rail 2 on the arc-shaped fence 1 from detaching from the slide 3.

[0036] Specifically, the driving wheel 4 is a flexible plastic rubber wheel. A warning light 13 is installed on the arc-shaped barrier 1.

[0037] The flexible plastic rubber wheel can improve the contact tightness between the driving wheel 4 and the slide rails 2 on the two arc-shaped fences 1, thereby improving the transmission efficiency of the driving wheel 4 and the slide rails 2; and the warning light 13 can have a good warning effect on approaching personnel, so as to prevent irrelevant personnel from further entering the fence device.

[0038] The use process of the automatic fence device provided by the present invention is as follows: in the unused state, the middle parts of the two arc-shaped fences 1 are both located on the upper part of the cart 14, the cart 14 is moved to the desired construction position, the driving motor 5 drives the driving wheel 4 to rotate, and the driving wheel 4 drives the two arc-shaped fences 1 to move synchronously in the opposite direction, so that the two arc-shaped fences are enclosed into a semicircle, then the linear feed drive 10 is started, and the roller 8 moves down along the roller groove until the scissor rod group 7 is fully extended, and the telescopic fence is rotated so that the fence device is enclosed with the external wall. Figure 1 The status shown or Figure 4 The state shown is sufficient, and the operator can enter the fence device from the connection between the telescopic fence and the wall or enter the fence device through the contact between the two telescopic fences.
