Description

Technical Field

[0001] This utility model relates to the field of hydroelectric insulation technology, and in particular to a tensioning mechanism and a roller frame type insulation baffle device. Background Technology

[0002] Live-line working refers to the method of performing maintenance and testing on high-voltage electrical equipment without interrupting power. Electrical equipment requires frequent testing, inspection, and maintenance during long-term operation. Live-line working is an effective measure to avoid power outages during maintenance and ensure normal power supply. Live-line working can be divided into several aspects, including live-line testing, live-line inspection, and live-line maintenance. The objects of live-line working include electrical equipment in power plants and substations, overhead transmission lines, distribution lines, and distribution equipment. The main tasks of live-line working include: replacing line tower insulators under energized conditions, cleaning and replacing insulators, flushing insulators with water, crimping and repairing conductors and overhead ground wires, inspecting faulty insulators, testing and replacing disconnecting switches and surge arresters, and testing transformer temperature rise and dielectric loss values.

[0003] During the operation of busbars within electrical control panels in hydropower stations, insulating baffles play a crucial role in preventing accidental contact with live parts, reducing the risk of electric shock, and ensuring personal safety. However, during power outages for busbar maintenance within electrical control panels, some insulating baffles need to be repeatedly removed for maintenance personnel, resulting in time-consuming and labor-intensive work, low efficiency, and injuries due to improper installation or removal. Currently, most insulating baffles within electrical control panels on the market are fixed installations, lacking flexibility and inconvenient to dismantle, making it difficult to meet the needs of hydropower station quality improvement and efficiency enhancement.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figure 1This is the first embodiment of the present invention, which provides a tensioning mechanism, including a bearing assembly 1, comprising a bearing plate 11 and a baffle 13 disposed inside the bearing plate 11; and,

[0031] Mounting assembly 2 includes cover plates 21 located at both ends of the support plate 11 and placement grooves 212 formed inside the cover plates 21; and,

[0032] The tensioning assembly 3 includes a fixing rod 31 located inside the placement groove 212. The operator can quickly adjust the height of the baffle 13 using the tensioning assembly 3. During the adjustment process, the fixing rod 31 of the tensioning assembly 3 will press against the baffle 13, keeping it in a taut state, effectively preventing the baffle 13 from wrinkling or stacking during the winding process, and reducing material displacement caused by the slack of the baffle 13.

[0033] The support assembly 1 also includes a mounting plate 12 disposed above the support plate 11. The inner side of the mounting plate 12 is provided with mounting holes 121. Through the mounting plate 12 above the support plate 11, the baffle device can be installed and fixed by screws to the mounting holes 121 on the mounting plate 12.

[0034] The inner side of the bearing plate 11 is provided with a bearing groove 111, and one end of the bearing groove 111 is provided with a sliding groove 112.

[0035] Usage process: First, the staff adjusts the height of the baffle 13 to the appropriate position. Then, the baffle 13 needs to be rolled up. At this time, the tensioning component 3 squeezes the baffle 13, thereby putting the baffle 13 in a tensioned state to prevent wrinkles and stacking during the rolling process.

[0036] Example 2

[0037] Reference Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes a mounting component 2 with connecting holes 211 around the cover plate 21. The connecting holes 211 correspond to the support plate 11, and a support hole 22 is provided on the inner side of the cover plate 21.

[0038] The tensioning assembly 3 also includes a limiting plate 311 located at one end of the fixed rod 31. A sliding block 32 is sleeved on the outside of the fixed rod 31, and a tensioning roller 34 is provided between the sliding blocks 32. A first elastic element 33 is sleeved on the outside of the fixed rod 31. Through the simple structural design of the tensioning assembly 3, the baffle 13 can be quickly tensioned and adjusted, and it has the characteristics of convenient adjustment and stable tensioning effect.

[0039] Usage process: When the baffle 13 is wound up and reset, the baffle 13 will wrinkle during the winding process. At this time, under the action of the elastic force of the first elastic element 33, the elastic potential energy generated by the first elastic element 33 pushes the sliding block 32 to move to the outside of the fixed rod 31. Then, the sliding block 32 drives the tension roller 34 to move. During the movement, the tension roller 34 will squeeze the baffle 13, so that the baffle 13 is in a relatively tight state during the winding process, thereby preventing wrinkles from occurring during the winding process.

[0040] Example 3

[0041] Reference Figures 1-4 This is the third embodiment of the present invention, which further provides a reel-type insulating baffle device. It includes a winding assembly 4, which includes a rotating rod 41 disposed inside the support hole 22; and...

[0042] The sliding component 5 includes a counterweight 52 located below the baffle 13.

[0043] The winding assembly 4 also includes an interlaced disk 43 located outside the rotating rod 41, and a rotating disk 44 located outside the rotating rod 41. The interlaced disk 43 and the rotating disk 44 are arranged in an array outside the rotating rod 41, and the interlaced disk 43 and the rotating disk 44 are staggered. A transmission groove 441 is provided above the rotating disk 44. A winding rod 45 is sleeved on the outside of the rotating rod 41, and a transmission block 451 is provided on the inner side of the winding rod 45. The transmission block 451 fits into the transmission groove 441. Through the mutual cooperation between the transmission block 451 and the transmission groove 441, when the winding rod 45 rotates, the transmission block 451 on the inner side of the winding rod 45 will be embedded in the transmission groove 441 and form a locking, thereby causing the winding rod 45 to drive the rotating disk 44 to move.

[0044] The outer side of the rotating rod 41 is provided with a second elastic element 42, which is a coil spring. The other end of the second elastic element 42 is connected to the cover plate 21. The elastic force of the second elastic element 42 forms a gravitational balance with the counterweight 52 below the baffle 13. If the baffle 13 automatically rolls back after being pulled down, a suitable counterweight 52 is installed at the lower end of the baffle 13 to maintain balance and achieve suspension at any position.

[0045] The sliding component 5 also includes a guide plate 51 located outside the counterweight 52. The guide plate 51 has a guide groove 511 on its inner side. The counterweight 52 below the baffle 13 enables the baffle to be suspended at any position, which greatly facilitates scenarios that require temporary isolation or protection.

[0046] Usage process: First, the baffle 13 is manually adjusted by the staff. The baffle 13 drives the outer winding rod 45 to rotate. The winding rod 45 drives the rotating disk 44 to rotate through the cooperation of the transmission block 451 and the transmission groove 441. At this time, the rotating disk 44 drives the rotating rod 41 to rotate. During the rotation of the rotating rod 41, the rotating rod 41 will drive the second elastic element 42 to deform, so that the second elastic element 42 generates elastic potential energy. The weight of the counterweight 52 below the baffle 13 and the elastic potential energy generated by the second elastic element 42 are balanced. Therefore, when the staff releases the baffle 13, it will not retract and thus maintain the adjusted state.
