[0002] The energy secondary system is the short name for the signaling and control system in the power grid. To transmit power from a power plant to distant locations, the voltage must be increased to high voltage to reach the user nearby, and then, when necessary, the voltage reduced. Control over this voltage increase and decrease, as well as the safety of the energy transmission process, relies on the substation in the main control room of the secondary system.In the power system, the substation's main control room, protective measuring and control cabinet, and activity space are limited. Personnel are required to remove relay protection devices from the corresponding terminals of the test equipment and connect the secondary line. Other adjacent operating equipment on the secondary line is very close. Incorrect contact or removal will not only result in personal electric shock injuries but also in power line accidents. Therefore, in all or part of the electrified operation, the control panel (cabinet) used for work, maintenance equipment, and operating equipment should be clearly separated from the front and back by a marking.In existing technology, the maintenance of the red tape on the terminal rows plays a warning role, but due to the constraints of the tape's adhesion, factors such as the tape's impact on its warning function are not strong; the tape often falls off easily, thus losing its role and ultimately potentially leading to safety risks.

[0026] In the Fig. Figures 1 to 5 show a first embodiment of the utility model, which has a clamping mechanism with an adjustment arrangement 100, a clamping assembly 200 and a fastening assembly 300.

[0027] In particular, the adjusting arrangement 100 comprises a mounting seat 101, a first square recess 102 arranged within the inner wall of the mounting seat 101, a sliding groove 103 arranged within the first square recess 102, and a plurality of arcuate through holes 104 arranged in the outer wall of the mounting seat 101, the mounting seat 101 being provided with a plurality of holes; a clamping assembly 200, the clamping assembly 200 being provided within the first square recess 102 and comprising a movable block 201, a sliding plate 202 provided on both sides of the movable block 201, and a gripping clamp 203 provided on the lower outer wall of the movable block 201;The fastening assembly 300 is arranged on the inner wall of the fastening seat 101 and comprises a threaded through hole 301 that is open in the inner wall of the fastening seat 101, a threaded rod 302 that is arranged inside the threaded through hole 301, and a handrail 303 that is arranged at one end of the threaded rod 302.

[0028] A sliding rod 201a is provided on both sides of the outer wall of the movable block 201, a first stop ring 201b is provided on one side of the sliding rod 201a, the sliding rod 201a slides in conjunction with the arcuate through-hole 104, and the first stop ring 201b interacts with the outer wall of the arcuate through-hole 104 to limit its position. A spring 201c is provided on a side wall of the movable block 201, a resistance plate 201d is provided on one side of the spring 201c, the spring 201c is fixedly connected to the movable block 201, and the resistance plate 201d is fixedly connected to the spring 201c.The sliding plate 202 is fixedly connected to the movable block 201. The sliding plate 202 is moved in the sliding groove 103 to move in conjunction with the sliding action. The gripping clamp 203 is fixedly connected to the movable block 201, and the threaded rod 302 is attached in conjunction with the threaded through-hole 301. One end of the threaded rod 302 rests against the resistance plate 201d. The handrail 303 is fixedly connected to the threaded rod 302, and the handrail 303 rests against the outer wall of the mounting seat 101 to limit its position.

[0029] Operating procedure: When the device is used for clamping the terminal rows, since the mounting seat 101 is provided with two, the operator first holds the first stop ring 201b on one side of the mounting seat 101, which is connected to the fabric roll 403, and pulls it towards both sides of the mounting seat 101, causing the mounting seat 101 to slide as it is stretched by the operator. The sliding plate 202 slides in the sliding groove 103, which in turn drives the sliding rod 201a to slide and move into a specific position in the arc-shaped through-bore 104. Then, the operator holds the retaining ring on the other side and pulls it towards both sides of the mounting seat 101, with one side of the resistance plate 201d resisting one side of the threaded rod 302 and the gripping clamp 203 being firmly seated on the terminal row.By adjusting the adjusting arrangement 100, the device can be adapted to terminal rows of different sizes, and by adjusting the clamping assembly 200, the fabric roll 403 can be firmly clamped to the terminal row by the interaction of the adjusting arrangement 100, the clamping assembly 200 and the fastening assembly 300, which is not easy to loosen, and it can be separated before and after the maintenance equipment and the operating equipment by a clear sign to prevent the occurrence of a potential safety risk. Design 2

[0030] In the Fig. Figures 1 to 5 show a second embodiment of the utility model, which is based on the previous embodiment.

[0031] In particular, a sliding rod 201a is provided on both sides of the outer wall of the movable block 201, a first stop ring 201b is provided on one side of the sliding rod 201a, and the sliding rod 201a slides in conjunction with the arcuate through-hole 104. The first stop ring 201b interacts with the outer wall of the arcuate through-hole 104 to limit the position, and a spring 201c is provided on one side of the side wall of the movable block 201, and a resistance plate 201d is provided on one side of the spring 201c, and the spring 201c is fixedly connected to the movable block 201. The resistance plate 201d is fixedly connected to the spring 201c, the sliding plate 202 is fixedly connected to the movable block 201, the sliding plate 202 is moved in the sliding groove 103 to cooperate with the movement, and the gripping clamp 203 is fixedly connected to the movable block 201.The threaded rod 302 is fastened in conjunction with the threaded through hole 301, one end of the threaded rod 302 is supported in conjunction with the resistance plate 201d, the handrail 303 is firmly connected to the threaded rod 302, and the handrail 303 is limited in conjunction with the outer wall of the mounting seat 101.

[0032] The rest of the structure is the same as in embodiment 1.

[0033] Actuation procedure: After the gripping clamp 203 is clamped onto the end row, it can release due to the instability of the spring 201c. At this point, the operator only needs to hold the handrail 303 at one end of the threaded rod 302 and rotate it towards the center of the fixed seat 101. Since the inner wall of the fixed seat 101 has a threaded hole, the threaded rod 302 is set in motion when the handrail 303 is rotated at one end towards the center of the fixed seat 101. During this movement, one end of the threaded rod 302 and the resistance plate 201d press against the spring 201c and compress it. Under the action of the spring 201c, the elasticity of the gripping clamp 203 on the end row causes it to snap shut more tightly.During disassembly, it is sufficient to hold the handrail 303 and screw the threaded rod 302 in the opposite direction. This resets the spring 201c, causing the sliding plate 202 to move in the sliding groove 103, which in turn moves the fixed fitting 101. At this point, the gripping clamp 203 no longer holds the clamping strip, allowing the device to be removed from the clamping strip. The clamping strip is then further secured by adjusting the fastening assembly 300. Embodiment 3

[0034] In Fig. Figure 6 shows a third embodiment of the utility model, which is based on the previous embodiment.

[0035] In particular, the holding arrangement 400 is provided above the mounting seat 101 and comprises a circular through-hole 401 which is opened in a side wall above the mounting seat 101, a first pivot axis 402 which is provided inside the circular through-hole 401, a fabric roll 403 which is firmly attached to an outer wall of the first pivot axis 402, and a spool 404 which is provided around the fabric roll 403.

[0036] The first pivot axis 402 is provided at one end with a second stop ring 402a, the second stop ring 402a is provided with a constriction on one side of the outer wall of the second stop ring 402a in conjunction with one side of the outer wall of the stationary seat 101, the first pivot shaft 402 rotates in conjunction with the circular through hole 401, and the fabric roll 403 is provided with a fastening rod 403a on one side of the fabric roll 403. A second rotating shaft 403b is provided on both sides of the fastening rod 403a, a third stop ring 403c is provided on one side of the second rotating shaft 403b, an outer wall of one side of the third stop ring 403c is bounded in conjunction with an outer wall of one side of the fastening seat 101, and the second rotating shaft 403b is rotated in conjunction with the circular through hole 401.The outer wall of one side of the spool 404 is provided with a square through-hole 404a, the square through-hole 404a interacts with the fabric roll 403 to expand and contract, and both sides of the spool 404 are provided with through-holes that interact with the first rotating shaft 402, the first rotating shaft 402 and the second rotating shaft 403b have the same diameter, and the two mounting seats 101 are identical, so that the first rotating shaft 402 and the second rotating shaft 403b interact with the circular through-hole 401.

[0037] The rest of the structure is the same as in embodiment 2.

[0038] Operating principle: When the gripping clamp 203 is attached to a mounting seat 101 on the clamping row, the operator only needs to hold the third stop ring 403c on the mounting rod 403a on one side of the fabric roll 403 and then stretch it outwards. At this point, the fabric roll 403 rotates about the first pivot axis 402 as it is stretched outwards, extending the red fabric roll 403 to the desired coverage, and then the other mounting seat 101 engages on the clamping row. When the device is not in use and the red fabric roll 403 needs to be removed, it is sufficient to engage the mounting seat 101 with the end of the mounting rod 403a, remove the mounting seat 101 with the end of the spool 404, and then hold and rotate the third retaining ring 403c, which in turn causes the second pivot shaft 403b to rotate.Since the red fabric roll 403 is firmly laminated in the spool 404, the red fabric roll 403 is pulled back layer by layer during rotation until the fastening rod 403a is fixed in conjunction with the square through hole 404a.
