Description

Technical Field

[0001] This utility model relates to the field of power equipment isolation technology, specifically to an equipment isolation warning sign. Background Technology

[0002] In power systems, relay protection devices are used to protect the power system and its components (generators, transformers, transmission lines, busbars, etc.) from damage. They are crucial equipment in substations, and their safe operation directly affects the safe operation of the power grid and even the entire power system. Current substation designs often install protection devices from different bays on the same protection panel to save space and cabinet costs. However, during maintenance, especially when maintaining a single bay, there is a risk of accidentally touching or misoperating the protection devices of operating equipment on the same panel when the protection device being maintained is also on the same panel.

[0003] Patent CN109921323B discloses an isolation device for protective screen operating equipment, including a flexible shielding layer, a main scroll rod and a secondary scroll rod respectively disposed on the left and right sides of the flexible shielding layer. Both the main scroll rod and the secondary scroll rod are hollow rods, with several magnetic strips bonded inside each hollow rod. A rotating shaft is disposed inside the main scroll rod, and an elongated hole is formed in the side wall of the main scroll rod. One side of the flexible shielding layer passes through the elongated hole and is fixed to the rotating shaft rod. Support rods are respectively disposed at both ends of the rotating shaft rod. An arc-shaped piece perpendicular to the support rod is disposed at the outer end of the support rod. A circumferential guide rail adapted to the arc-shaped piece is disposed on the inner wall of the main scroll rod, and the arc-shaped piece extends into the circumferential guide rail. Caps are disposed at both ends of the main scroll rod, corresponding to the openings of the rotating shaft rod, and both ends of the rotating shaft rod pass through the caps. This device serves as a warning, preventing misoperation and reducing the probability of accidents. Furthermore, the protective screen's operating equipment isolation device has a simple structure, making it easy to carry and use. Magnet strips are installed on the main and auxiliary shafts of the scroll, eliminating the need for additional support structures and resulting in a lighter overall weight. During use, it is installed at the location requiring shielding by magnetic attraction. Further, the main and auxiliary shafts are designed with an arc-shaped structure, with the magnet strips installed on the flat sidewalls of the arc-shaped structure. In use, the flat sidewalls have a larger attraction area compared to curved sidewalls, making the shielding structure more stable and less prone to slippage. During use, the flexible shielding layer is unfolded by pulling the auxiliary shaft; to retract it, the portion of the rotating shaft extending beyond the rotating shaft is rotated for winding. In this patent, the flexible shielding layer is attracted to the equipment via magnet strips on the outer wall of the main shaft. However, during use, when the location where the flexible shielding layer is placed is uneven or lacks a connection point, it is difficult to connect the flexible shielding layer to the location requiring shielding. Additionally, when retracting the flexible shielding layer, manual winding is required, resulting in low density between the flexible shielding layers and a large space occupation during the winding process.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] In one embodiment, see Figure 1 , 2 The present invention provides a device isolation warning sign 9, which includes a winding assembly and a connecting assembly.

[0023] The winding assembly includes a main winding drum 1 and a secondary connecting drum 2 that are detachably connected to each other, and a winding member 3 rotatably disposed within the main winding drum 1. The main winding drum 1 is provided with a first limiting member 4 and a second limiting member 5, and a locking member 6. The first limiting member 4 and the winding member 3 are located on the same plane, and there is a horizontal gap between the second limiting member 5 and the first limiting member 4. A spring-loaded member 7 is provided between the winding member 3 and the main winding drum 1, and a flexible covering layer 8 is wound on the winding member 3. The end of the flexible covering layer 8 away from the winding member 3 passes through the second limiting member 5 and is connected to the secondary connecting drum 2. A warning sign 9 is provided on the flexible covering layer 8. The connecting assembly includes a first suction member 10 disposed on the main winding drum 1 and the secondary connecting drum 2, and a first connecting member 11 disposed on the main winding drum 1 and the secondary connecting drum 2. A second suction member 12 is provided on the first connecting member 11.

[0024] Further, see Figure 3 The main winding drum 1 has an installation cavity 13 inside, and a through groove 14 communicating with the installation cavity 13 is provided on the outer wall of the main winding drum 1. The winding component 3 is rotatably installed in the installation cavity 13, and one end of the flexible cover layer 8 passes through the through groove 14 and is connected to the winding component 3.

[0025] Preferably, the main take-up drum 1 is a hollow rectangular column, and the hollow interior of the main take-up drum 1 forms an installation cavity 13.

[0026] Preferably, the through groove 14 is parallel to the axis of the main take-up drum 1.

[0027] Further, see Figure 2 The auxiliary connecting cylinder 2 is provided with a slot 15, and the auxiliary connecting cylinder 2 is engaged with the main winding cylinder 1 through the slot 15.

[0028] Preferably, the auxiliary connecting cylinder 2 is a rectangular body with a "U" shaped cross-section, and a slot 15 is formed inside the auxiliary connecting cylinder 2, which is engaged with the outer wall of the main winding cylinder 1.

[0029] In the above configuration, the main take-up drum 1 is attached to the outer wall of the main take-up drum 1 via the slot 15, thereby drawing the main take-up drum 1 into the auxiliary connecting drum 2, connecting the main take-up drum 1 and the auxiliary connecting drum 2, and reducing the space occupied.

[0030] Further, see Figure 3 The take-up member 3 includes a take-up rod 301 rotatably disposed inside the main take-up drum 1, and a rotating disk 302 is provided on the take-up rod 301. There is a gap between the rotating disk 302 and the inner wall of the main take-up drum 1. The locking member 6 includes a locking stud 601, which abuts against the rotating disk 302 under the action of external force, thereby fixing the position of the take-up rod 301.

[0031] Preferably, bearings 16 are provided on the inner walls of both ends of the main winding drum 1, and the winding rod 301 is connected to the inner ring of the bearing 16.

[0032] Further, see Figure 3 The spring-loaded component 7 includes a spring-loaded coil spring, which is mounted on the winding rod 301. The two ends of the spring-loaded coil spring are fixedly connected to the winding rod 301 and the main winding drum 1, respectively.

[0033] Preferably, the spring is sleeved on the take-up bar 301 and located above the take-up reel.

[0034] In the above configuration, by setting a spring-loaded spring, when the flexible cover layer 8 is pulled away from the main winding drum 1, the spring-loaded spring contracts as the winding rod 301 rotates, and abuts against the rotating disk 302 by rotating the locking stud 601, thereby fixing the position of the winding rod 301, and the position of the flexible cover layer 8 is also fixed accordingly; when winding the flexible cover layer 8, the locking stud is loosened, and the winding rod 301 is rotated by the unfolding of the spring-loaded spring, and the flexible cover layer 8 is wound on the winding rod 301.

[0035] Further, see Figure 2 , 3 The first limiting member 4 includes two sets of first rollers 401 symmetrically arranged in the through groove 14, forming a first channel 402 between the two sets of first rollers 401; the second limiting member 5 includes two sets of second rollers 501 symmetrically arranged in the mounting cavity 13, forming a second channel 502 between the two sets of second rollers 501; the flexible covering layer 8 passes through the first channel 402 and the second channel 502 in sequence and is connected to the winding rod 301.

[0036] Preferably, a triangular structure is formed between the first channel 402, the second channel 502, and the winding rod 301.

[0037] In the above configuration, the flexible cover layer 8 passing through the first channel 402 and the second channel 502 is bent, which increases the resistance when the flexible cover layer 8 is rolled onto the take-up bar 301 through the first channel 402 and the second channel 502, thereby tightening the flexible cover layer 8 rolled onto the take-up bar 301.

[0038] Further, see Figure 2 The first connector 11 includes a first connecting rope 1101, the first adsorption member 10 includes a first adsorption magnet 1001, and the second adsorption member 12 includes a second adsorption magnet 1201.

[0039] Preferably, the first connecting rope 1101 is connected to the middle of the main winding drum 1 and the auxiliary connecting drum 2 respectively.

[0040] In the above setup, the device can be magnetically connected via the first adsorption magnet 1001 or the second adsorption magnet 1201. When the second adsorption magnet 1201 is connected to the device, the length of the first connecting rope 1101 can be adjusted by knotting, thereby controlling the position of the flexible cover layer 8 and facilitating the connection of the flexible cover layer 8 to the device.

[0041] In this embodiment, the flexible covering layer 8 is wound inside the main winding drum 1. The auxiliary connecting drum 2 is engaged with the main winding drum 1 through the slot 15, and the first connecting rope 1101 is wound around the main winding drum 1 and the auxiliary connecting drum 2. The first adsorption magnet 1001 and the second adsorption magnet 1201 are magnetically connected. When the flexible covering layer 8 is unfolded, the first connecting rope 1101 is unfolded, and the main winding drum 1 and the auxiliary connecting drum 2 are separated. The auxiliary connecting drum 2 or the second adsorption member 12 located on the auxiliary connecting drum 2 can be adsorbed and connected to the equipment first. The main winding drum 1 is pulled away from the auxiliary connecting drum 2 to unfold the flexible covering layer 8. Then, it is connected to the equipment through the first adsorption magnet 1001 or the second adsorption magnet 1201 on the main winding drum 1, so that the flexible covering layer 8 can cover the outside of the equipment. The position of the second adsorption member 12 connected to the equipment can be adjusted by tying the first connecting rope 1101.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
