Description

Technical Field

[0001] The utility model belongs to the technical field of switch station safety fences, and in particular relates to a fixed retractable safety fence applied to a switch station. Background Art

[0002] In order to ensure the safety of workers when performing electrical equipment maintenance, inspection, testing and other work in the switch station, arranging isolation measures between workers and live equipment is one of the important safety technical measures for operating personnel to obtain work permits. Safety fences are common isolation measures at power production sites and are the first line of defense to prevent workers from mistakenly entering live intervals.

[0003] At present, most switch station fences mainly use safety warning tapes as isolation measures. Although they play a certain visual warning role, many disadvantages are still revealed during long-term use. For example, the patent document with the publication number of CN219508431U discloses "a telescopic fence with a long-distance warning tape with a tape reel", which includes a tape reel installed on a base rod; the tape reel includes a core shaft connected to the base rod, on which a winding drum assembly for winding the warning tape is rotatably installed; a plurality of spring boxes are stacked and installed in the same direction inside the winding drum assembly; the spring box is sleeved on the core shaft; one end of the spring box is provided with a spring shaft sleeve protruding outward, and the other end is provided with a shaft sleeve hole; the spring shaft sleeves of adjacent spring boxes are inserted into adjacent shaft sleeve holes; the spring shaft sleeves are rotatably sleeved on the core shaft; a clockwork spring is installed in the spring box; the outer end of the clockwork spring is connected and fixed to the inner wall of the spring box, and the inner end is connected to the spring shaft sleeve of the adjacent spring box; the spring box at the head end is fixed to the winding drum assembly; the inner end of the clockwork spring of the spring box at the end is connected to the fixed shaft sleeve; the fixed shaft sleeve is sleeved and fixed on the core shaft.

[0004] Although the application can be combined with each other to eliminate the limiting factor of the isolation distance, on the one hand, the height of the warning belt cannot be adjusted, which may lead to the problem that the warning belt is too low and people can cross it at will; on the other hand, the current "State Grid Corporation Electric Power Safety Work Regulations Substation Part" Q / GDW 1799.1-2013 7.5.5 points out that when working on outdoor high-voltage equipment, fences should be installed around the work site, and the entrances and exits should be surrounded by the adjacent roads, with signs saying "Enter and exit from here!". An appropriate number of "Stop, high voltage danger!" signs should be hung on the fences around the work site, and the signs should face the inside of the fence. However, there is no specific sign hanging point on the device, so it cannot meet the use requirements of the switch station scene. Utility Model Content

[0005] The purpose of the utility model is to provide a fixed retractable safety fence applied to a switch station, which can adjust the height of the warning tape. At the same time, the hanging holes on the warning tape can facilitate the setting of signboards, which can better meet the use requirements of the switch station scene.

[0006] The technical solution adopted by the utility model is a fixed retractable safety fence applied to a switch station, comprising a base, a telescopic rod group and a warning tape, wherein the telescopic rod group is fixedly connected to the base, the warning tape is installed on the telescopic end of the telescopic rod group through a tape reel, and a plurality of hanging holes are evenly and equidistantly opened on the warning tape.

[0007] Furthermore, the telescopic rod group includes a sleeve, a first telescopic rod and a second telescopic rod, the bottom end of the sleeve is fixedly connected to the base, the first telescopic rod is inserted in the sleeve and can be telescopically adjusted relative to the sleeve, the second telescopic rod is inserted in the first telescopic rod and can be telescopically adjusted relative to the first telescopic rod, and the warning tape is installed on the top of the second telescopic rod through a tape reel.

[0008] Furthermore, a waterproof cover is mounted on the sleeve.

[0009] Furthermore, a buckle is installed at the movable end of the warning belt, and a slot adapted to the buckle is provided at the top end of the second telescopic rod.

[0010] Furthermore, a rainproof cover is arranged on the top surface of the second telescopic rod, and a handle is arranged on the top surface of the rainproof cover.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model is provided with a telescopic rod group, and the warning belt is installed at the top of the second telescopic rod, so the height of the warning belt can be adjusted, avoiding the problem that the warning belt is too low and people can cross it at will;

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer and more understandable, the technical solution of the utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, the utility model provides a fixed retractable safety fence applied to a switch station, comprising a base 1, a telescopic rod group and a warning tape 2, the telescopic rod group is fixedly connected to the base 1, the warning tape 2 is installed on the telescopic end of the telescopic rod group through a tape reel, and a plurality of hanging holes 3 are evenly and equidistantly opened on the warning tape 2.

[0018] The telescopic end of the telescopic rod group can be telescopically adjusted, so the height of the warning tape 2 can be changed to prevent the warning tape 2 from being too low and people from crossing over it at will.

[0019] The warning tape 2 is installed through a tape reel. The structure and principle of the tape reel are existing technologies. The tape reel can store the warning tape 2 at the telescopic end of the telescopic rod group. The user can pull the active end of the warning tape 2 to pull out the warning tape 2. At this time, the length of the pulled-out warning tape 2 can be selected according to the needs of the usage scenario. After the pulled-out warning tape 2 loses external tension, it will be retracted to the telescopic end of the telescopic rod group under the action of the tape reel.

[0020] A plurality of hanging holes 3 are provided on the warning tape 2. In the use scenario of the switch station, the staff can hang warning signs such as "Stop, high voltage danger!" on the hanging holes 3 to play a warning role.

[0021] The telescopic rod group includes a sleeve 4, a first telescopic rod 5 and a second telescopic rod 6. The bottom end of the sleeve 4 is fixedly connected to the base 1. The first telescopic rod 5 is inserted in the sleeve 4 and can be telescopically adjusted relative to the sleeve 4. The second telescopic rod 6 is inserted in the first telescopic rod 5 and can be telescopically adjusted relative to the first telescopic rod 5. The warning tape 2 is installed on the top of the second telescopic rod 6 through a tape reel.

[0022] In some examples, the first telescopic rod 5 and the sleeve 4, and the second telescopic rod 6 and the first telescopic rod 5 can be matched with each other through a buckle structure, so as to fix the height after the telescopic adjustment.

[0023] When in use, the extension length of the first telescopic rod 5 is adjusted first, until the first telescopic rod 5 is extended to the longest relative to the sleeve 4. If the height of the warning tape 2 still cannot meet the demand, the extension length of the second telescopic rod 6 is adjusted.

[0024] A waterproof cover 7 is provided on the sleeve 4. Since the sleeve 4 is at the bottom of the device, the waterproof cover 7 can protect the sleeve 4 from water. A rain cover 10 is provided on the top surface of the second telescopic rod 6. A handle 11 is provided on the top surface of the rain cover 10. The rain cover 10 can block rainwater to prevent rainwater from entering the second telescopic rod 6 and causing rust on the belt reel. The handle 11 makes it convenient for staff to move the device.

[0025] The movable end of the warning tape 2 is provided with a buckle 8, and the top of the second telescopic rod 6 is provided with a slot 9 adapted to the buckle 8. Most usage scenarios require a closed loop, and in this case, the buckle 8 on the warning tape 2 can be engaged in the slot 9 on the adjacent second telescopic rod 6 in the two nearest fences, and the closed loop enclosure can be formed by connecting them in sequence.
