Description

Technical Field

[0001] The present invention relates to the technical field of substation equipment maintenance, and particularly to a telescopic substation safety identification structure. Background Art

[0002] To ensure the safety of on-site work, when working in the substation equipment area, it is necessary to arrange temporary safety measures adapted to the site, and after the on-site work is completed, the on-site temporary safety measures need to be removed. Therefore, safety measures are a very important means to ensure safety in the power industry.

[0003] Currently, secondary switch cabinets are usually installed in the secondary equipment room of the substation to monitor the high-voltage equipment in the substation. When overhauling the secondary equipment room, a signboard with "Work Here!" and a red cloth curtain with "Equipment in Operation" need to be hung on the secondary switch cabinet for safety measure arrangement. Usually, the signboard is hung on the door handle of the protection switch cabinet door or placed on the ground, and the red cloth curtain is pasted with tape or magnetically attracted to the protection switch cabinet.

[0004] However, the above safety measure arrangement methods mainly have the following two problems: (1) The risk of misoperation, the main reason is that the magnets or adhesives used for the red cloth curtain have poor fixing properties and are easily removed by people. At the same time, the signboard is easily displaced due to the frequent movement of on-site operators; (2) Affecting the efficiency of intelligent inspection, the main reason is that the red cloth curtain blocks the operation device panel, resulting in the risk of incomplete inspection of operating equipment. Summary of the Invention

[0005] The technical problem to be solved by the embodiments of the present invention is to provide a telescopic substation safety identification structure that can be portably fixed on the secondary switch cabinet and can portably retract and expand the safety identification language, thereby avoiding the risk of misoperation and the risk of insufficient intelligent inspection efficiency in the existing method.

[0042] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] As Figures 1 to 5 shown, in the first embodiment of the present invention, a telescopic substation safety label structure is proposed, which is matched with a secondary switch cabinet (not shown), and includes a telescopic belt sleeve 1, a buckle mechanism 2 and a double-sided telescopic belt 3; wherein,

[0044] The telescopic belt sleeve 1 is fixed to one side of the cabinet door of the secondary switch cabinet and away from the cabinet door handle (not shown), and includes a sleeve 11 and a fixed shaft 12 (as Figure 2 shown); wherein, the sleeve 11 is fixed to the cabinet door of the secondary switch cabinet by screws; the fixed shaft 12 is arranged outside the sleeve 11, and a gap for surrounding the double-sided telescopic belt 3 is reserved between the fixed shaft 12 and the sleeve 11, that is, this gap is used for the double-sided telescopic belt 3 to pass through to realize surrounding the fixed shaft 12;

[0045] The buckle mechanism 2 is fixed to the other side of the cabinet door of the secondary switch cabinet and close to the cabinet door handle, and includes a fixed buckle 21, a first label movable buckle 22 and a second label movable buckle 23 (as Figure 3As shown in the figure; among them, the fixed buckle 21 is fixed to the cabinet door of the secondary cabinet by screws, and there is a spacing reserved between the fixed buckle 21 and the telescopic belt sleeve 1 for unfolding the double-sided telescopic belt 2, that is, it can stretch and display corresponding identification information; the first identification movable buckle 21 is detachably installed on one side of the fixed buckle, and is provided with a first traction column 221 for fixing one end of the double-sided telescopic belt 3; the second identification movable buckle 23 is detachably installed on the other side of the fixed buckle 21, and is provided with a second traction column 231 for fixing the other end of the double-sided telescopic belt 3;

[0046] The double-sided telescopic belt 3 includes a front side 31 with a first identification and a back side 32 with a second identification (as Figure 1 shown in the figure); among them, the double-sided telescopic belt 3 is made of a flexible material (such as flexible cloth), the information of the first identification is that the equipment is in operation; the information of the second identification is working here;

[0047] Among them, after both the first identification movable buckle 22 and the second identification movable buckle 23 are detached from the fixed buckle 21, fix one end of the double-sided telescopic belt 2 to the first traction column 221, and stretch the other end of the double-sided telescopic belt 3 in the direction away from the cabinet door handle (for example, the left direction) through the gap between the fixed shaft 12 and the sleeve 11 to surround the fixed shaft 12, and then further stretch it in the direction towards the cabinet door handle (for example, the right reverse direction) and fix it to the second traction column 231;

[0048] If the first identification movable buckle 22 is locked in the fixed buckle 21, the front side of the double-sided telescopic belt 3 is exposed to display the first identification (as Figure 4 shown in the figure); or, if the second identification movable buckle 23 is locked in the fixed buckle 21, the back side of the double-sided telescopic belt 3 is exposed to display the second identification (as Figure 5 shown in the figure).

[0049] It should be noted that the present invention ingeniously adopts the coaxial three-column principle. By pulling the movable buckles with different identifications, the first identification of "the equipment is in operation" on the front side and the second identification of "working here" on the back side can be respectively displayed. At the same time, during the display process of the first identification and the second identification, only the corresponding movable buckle is installed in the fixed buckle 21, and the other movable buckle needs to be detached from the fixed buckle 21 and be close to the vicinity of the telescopic belt sleeve 1.

[0050] In the first embodiment of the present invention, both the first identification movable buckle 22 and the second identification movable buckle 23 are locked or detached from the fixed buckle 21 through a locking mechanism;

[0051] The locking mechanism includes a key lock 4, a buckle spring (not shown), a fixing rod 5, and a key connecting rod 6. Among them, the key lock 4 is fixed at the middle position of the corresponding identification movable buckle and is connected to one end of the fixing rod 5. Its locking tongue (not shown) is connected to one end of the key connecting rod 6 through the buckle spring. The other end of the fixing rod 5 is detachably installed at a corresponding position on one side of the fixed buckle 21 (such as a groove at the corresponding position). The other end of the key connecting rod 6 is detachably installed at a corresponding position on the other side of the fixed buckle 21 (such as a groove at another corresponding position).

[0052] Among them, after the fixing rod 5 on the first identification movable buckle 22 or the second identification movable buckle 23 is installed on the fixed buckle 21, when the corresponding key lock 4 is rotated forward, the corresponding key connecting rod 6 is driven to extend and can be installed at the corresponding position of the fixed buckle 21, so as to lock the first identification movable buckle 22 or the second identification movable buckle 23 with the fixed buckle 21. On the contrary, when the corresponding key lock 4 is rotated reversely, the corresponding key connecting rod 6 is driven to retract and can be removed from the corresponding position of the fixed buckle 21, and the corresponding fixing rod 5 is removed from the fixed buckle 21, so as to separate the first identification movable buckle 22 or the second identification movable buckle 23 from the fixed buckle 21.

[0053] In the first embodiment of the present invention, the installation position of the first identification movable buckle 22 on one side of the fixed buckle 21 is far from the telescopic belt sleeve 1, and the installation position of the second identification movable buckle 23 on the other side of the fixed buckle 21 faces the telescopic belt sleeve 1. That is, the fixing position of the first identification movable buckle 22 of the first identification is higher and more to the right than the fixing position of the second identification movable buckle 23 of the second identification, which can block the cabinet door handle. At this time, the height of the first traction column 221 from the cabinet door of the secondary switch cabinet is higher than the height of the second traction column 231 from the cabinet door of the secondary switch cabinet.

[0054] In the first embodiment of the present invention, a hollow groove 211 for accommodating and buckling the cabinet door handle is provided in the middle part of the fixed buckle 21. In this way, the cabinet door handle can be used to prevent the fixed buckle 21 from falling off downward, so that the fixed buckle 21 can be hung on the cabinet door handle, further enhancing the fixation with the cabinet door.

[0055] Corresponding to a telescopic substation safety identification structure proposed in the first embodiment of the present invention, the second embodiment of the present invention also proposes another telescopic substation safety identification structure, which includes the structure and connection relationship of a telescopic substation safety identification structure proposed in the first embodiment of the present invention. For specific details, please refer to the relevant content described in the first embodiment of the present invention, and will not be elaborated here one by one.

[0056] At this time, another retractable substation safety sign structure proposed in the second embodiment of the present invention is based on a retractable substation safety sign structure proposed in the first embodiment of the present invention, and further structural design is carried out on the sleeve 11, such as Figure 6 as shown. In Figure 6 , a spring structure and a retractable belt rotating shaft 112 are built in the sleeve 11; the spring structure is two disc springs 111 (such as clockwork springs) wound around both ends of the retractable belt rotating shaft 112 and driving the retractable belt rotating shaft 112 to rotate synchronously; the retractable belt rotating shaft 112 is provided with a fixed position (not shown) fixed to the double-sided retractable belt 3; wherein, when one end of the double-sided retractable belt 3 is fixed to the first traction column 221 and the other end is fixed to the fixed position provided on the retractable belt rotating shaft 112, the double-sided retractable belt 3 is wound around the fixed shaft 12 and the second traction column 231 in sequence. At this time, when the double-sided retractable belt 3 is wound around the fixed shaft 12, its front side 31 faces the sleeve 11; when the double-sided retractable belt 3 is wound around the second traction column 231, a part of its front side 31 is in contact with the outer surface of the second traction column 231.

[0057] At this time, the two disc springs 111 can drive the retractable belt rotating shaft 112 to rotate, so as to collect or unfold the external double-sided retractable belt 3. In Figure 7 and Figure 8 , the double-sided retractable belt 3 corresponding to the displayed sign can be pulled by pulling different traction columns.

[0058] It can be seen that when removing, only need to use a special key to remove the first sign movable buckle 22 and the second sign movable buckle 23, and the spring structure in the retractable belt sleeve 1 will automatically retract the double-sided retractable belt 3. When using, pull the double-sided retractable belt 3, and when the first sign movable buckle 22 or the second sign movable buckle 23 is located in the fixed buckle 21, lock it with a special key. Therefore, it is more convenient and fast to use, and it is convenient and fast to install and remove.

[0059] Such as Figure 9 shown, it is the installation effect diagram of a retractable substation safety sign structure provided by the first embodiment or the second embodiment of the present invention.

[0060] Implementing the embodiments of the present invention has the following beneficial effects:

[0061] 1. The substation safety sign structure of the present invention is directly fixed (such as with screws) at the cabinet door of the secondary switch cabinet, and has better fixity than the red cloth curtain adsorbed by magnets or pasted with adhesive tape, and the signboards placed or hung arbitrarily.

[0062] 2. When dismantling the substation safety identification structure of the present invention, it is only necessary to use a special key to unlock the first identification active buckle and the second identification active buckle. The spring structure in the telescopic belt sleeve will automatically retract the double-sided telescopic belt. When in use, pull the double-sided telescopic belt, wait for the first identification active buckle or the second identification active buckle to be located in the fixed buckle, and then lock it with a special key. It is more convenient and quick to use than red curtains and identification plates that need to be sorted and collected, and it is convenient and quick to install and remove;

[0063] 3. The substation safety identification structure of the present invention will not block the secondary equipment to be inspected, and will not affect manual and robot inspections;

[0064] 4. After the first sign "equipment in operation" on the front is installed, the double-sided retractable buckle will block the cabinet door handle and a special key is required to open the buckle, which is equivalent to locking the cabinet door, effectively avoiding the staff from misoperating due to walking into the wrong cabinet; in addition, after the second sign "work here" on the back is installed, the double-sided retractable buckle will not block the cabinet door handle, making it convenient for the staff to perform maintenance and inspection work here, thereby having a locking function and avoiding the risk of misoperation;

[0065] 5. The substation safety identification structure of the present invention has a simple structure, is easy to install, is simple and easy to use, has significantly improved efficiency, and has strong practicality.

[0066] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
