Description

Technical Field

[0001] The utility model relates to the technical field of arc probe installation, in particular to a mounting bracket for an arc probe. Background Art

[0002] Once a fault occurs in the power system, a huge arc light will be generated. When the arc light occurs, a large amount of light energy radiation and very high temperature radiation will be generated. These radiations have a great destructive effect on the power system. Therefore, some power systems will install fiber optic arc sensors to monitor the power system. The fiber optic arc light sensor mainly includes an arc probe, an optical fiber and a photoelectric conversion unit. The fiber optic arc light sensor can detect the intensity of the arc light and then determine whether the system power supply needs to be cut off based on the intensity of the arc light.

[0003] Existing arc probe installation methods mostly include guide rail, bracket, and direct installation. The guide rail requires the installation of a guide rail within the installation area. Therefore, the traditional bracket disassembly and assembly steps are complicated. In addition, due to the fixed structure of the traditional bracket, it is difficult to adjust the arc probe at multiple angles after installation. Therefore, the use range and angle of the arc probe are limited, thereby reducing the installation efficiency of the arc probe.

[0004] In view of the technical defects in this aspect, a solution is now proposed. Utility Model Content

[0005] The purpose of the present invention is to realize the simple disassembly and assembly of multiple arc light probes by setting an installation frame, a limit frame, a clamping assembly and a clamping frame, and to facilitate the angle adjustment of the arc light probe after installation, so as to adapt to various installation conditions and improve installation efficiency.

[0006] The purpose of the utility model can be achieved through the following technical solutions: an installation bracket of an arc probe, comprising an installation frame and a limit frame of a ring-shaped structure, the limit frame being movably arranged inside the installation frame, and a rotating shaft is commonly provided between the centers of the two side surfaces of the limit frame and the inner walls of the two sides of the installation frame, and the rotating shaft and the inner wall of the installation frame are hinged, a horizontal plate is fixedly installed at the middle section of the rear end surface of the limit frame, and a sliding groove is provided on the upper and lower end surfaces of the limit frame, and a vertical plate is slidably connected to the front end between the two groups of the sliding grooves, and the surface of the vertical plate is provided with limiting grooves at the upper and lower ends, a threaded push rod 1 is rotatably connected to the center of the rear end of the vertical plate, and the rod body of the threaded push rod 1 is threadedly connected to the center of the horizontal plate and extends to the rear end of the horizontal plate, and a clamping assembly is provided on the outside of each group of the limit grooves.

[0007] Furthermore, the clamping assembly includes two groups of symmetrical push plates, which are movably installed on the front end surface of the vertical plate and located on both sides of the limiting groove, and a circular shaft is fixedly installed at the center of the rear end surface of the push plate. The circular shaft is slidably connected to the inside of the transverse groove opened on one side of the limiting groove on the front end surface of the vertical plate, and a spring damping shock absorber is arranged between the circular shaft and the inner wall on the other side of the transverse groove.

[0008] Furthermore, semicircular slots are provided on opposite surfaces of the two groups of push pieces, and the two groups of push pieces are arranged at a side away from each other and at the rear end in an oblique manner.

[0009] Furthermore, positioning plates are fixedly installed on the inner walls of both sides of the limit frame at the rear end of the vertical plate, and the front end surfaces of the two groups of positioning plates are arranged in an oblique section opposite to the abutment piece.

[0010] Furthermore, both sides of the limit frame are provided with folding grooves at the bottom, and a clamping frame with a concave structure is movably connected between the two groups of folding grooves, and limiting discs are fixedly installed on the inner walls of both sides of the clamping frame at the top.

[0011] Furthermore, the two groups of limiting discs are respectively slidably connected to the bending parts inside the two groups of folding grooves, and the center of the bottom of the clamping frame is rotatably connected to a second threaded push rod, and the bottom thread of the second threaded push rod passes through the bottom frame of the installation frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a vertical plate, a threaded push rod, a limit groove and a clamping assembly. The end of the arc probe is inserted into the limit groove. The threaded push rod is turned to pull the vertical plate, the arc probe and the clamping assembly back and forth. When the vertical plate moves backward, the retaining piece moves backward and gradually approaches the corresponding positioning plate, and the beveled end of the retaining piece moves along the bevel of the positioning plate and is moved toward the limit groove by the retaining piece. The two groups of retaining pieces in the same row approach each other until the two groups of corresponding semicircular grooves overlap and clamp the end of the arc probe together. The arc probe can be quickly locked to improve the installation efficiency of the arc probe.

[0014] 2. The utility model provides a clamping frame, a limiting disc and a threaded push rod. By rotating the threaded push rod clockwise or counterclockwise, the threaded push rod and the clamping frame are forced to move up and down. When the clamping frame moves upward, the limiting disc slides to the inside of the upper half of the inclined groove of the folding groove, and the limiting disc presses against the inclined inner wall of the top of the folding groove, forcing the limiting frame to flip clockwise. Conversely, when the clamping frame moves downward, the limiting disc slides to the inside of the lower half of the inclined groove of the folding groove, and the limiting disc presses against the inclined inner wall of the bottom of the folding groove, forcing the limiting frame to flip clockwise, thereby facilitating the adjustment of the installation angle of the arc probe and being suitable for installation in multiple scenarios.

[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] Example 1:

[0024] See also Figure 1 - Figure 5As shown, an arc probe mounting bracket includes a mounting frame 1 and a limit frame 2 of a circular structure. The limit frame 2 is movably arranged inside the mounting frame 1. A rotating shaft 3 is provided between the center of both sides of the limit frame 2 and the inner walls of both sides of the mounting frame 1, and the rotating shaft 3 is hinged to the inner wall of the mounting frame 1. A horizontal plate 4 is fixedly installed at the middle section of the rear end surface of the limit frame 2. A slide groove 5 is provided on the upper and lower end surfaces of the limit frame 2. A vertical plate 6 is slidably connected to the front end of the two sets of slide grooves 5. The surface of the plate 6 is provided with limit grooves 7 at the upper and lower ends. The rear center of the vertical plate 6 is rotatably connected to a threaded push rod 8, and the rod body of the threaded push rod 8 is threadedly connected to the center of the horizontal plate 4 and extends to the rear end of the horizontal plate 4. A clamping assembly 9 is provided on the outside of each set of limit grooves 7. First, the connecting ends of the two sets of arc probes are inserted into the corresponding limit grooves 7, and then the threaded push rod 8 is twisted to pull the vertical plate 6 to move backward along the inside of the slide groove 5, and the arc probe and the clamping assembly 9 are moved backward at the same time.

[0025] The clamping assembly 9 includes two groups of symmetrical pieces 901, which are movably mounted on the front end surface of the vertical plate 6 and located on both sides of the limiting groove 7, and a circular shaft 902 is fixedly mounted at the center of the rear end surface of the piece 901, and the circular shaft 902 is slidably connected to the inside of the transverse groove 903 opened on the front end surface of the vertical plate 6 on one side of the limiting groove 7, and a spring damping shock absorber 904 is provided between the circular shaft 902 and the inner wall on the other side of the transverse groove 903, and semicircular card grooves 905 are opened on the opposite surfaces of the two groups of pieces 901. The two groups of pieces 901 are arranged with a side away from each other and are located at the rear end in an oblique section. The inner walls on both sides of the limit frame 2 are located at the rear end of the vertical plate 6 and are fixed with positioning plates 906. The front ends of the two groups of positioning plates 906 are arranged with an oblique section opposite to the piece 901;

[0026] The push piece 901 moves backward and gradually approaches the corresponding positioning plate 906, and the beveled end of the push piece 901 moves along the bevel of the positioning plate 906, and is pushed to move toward the limit groove 7. The two groups of push pieces 901 in the same row approach each other until the two groups of corresponding semicircular grooves 905 overlap and clamp the end of the arc probe together, and then the backward pulling of the vertical plate 6 can be stopped, so that the arc probe is limited; and in the process of moving the push piece 901, the circular shaft 902 slides along the inside of the transverse groove 903 and presses the spring damping shock absorber 904, forcing the push piece 901 to move smoothly; and when the arc probe is removed, the vertical plate 6, the arc probe and its clamping assembly 9 can be moved forward by rotating in the opposite direction, because the push piece 901 loses the pressure of the positioning plate 906 and quickly resets under the rebound force of the spring damping shock absorber 904, so as to lose the clamping of the arc probe, thereby improving the disassembly and assembly efficiency of the arc probe.

[0027] Example 2:

[0028] See also Figure 1 and Figure 5As shown, both sides of the limit frame 2 are provided with folding grooves 10 at the bottom end, and a clamping frame 11 with a concave structure is movably connected between the two groups of folding grooves 10, and the inner walls on both sides of the clamping frame 11 are fixedly installed at the top end. The two groups of limit discs 12 are respectively slidably connected to the bending parts inside the two groups of folding grooves 10, and a threaded push rod 2 13 is rotatably connected at the center of the bottom of the clamping frame 11, and the bottom thread of the threaded push rod 2 13 passes through the bottom frame of the mounting frame 1;

[0029] After the arc probe is installed, the installation angle of the probe is adjusted in time according to the actual required search angle. By rotating the threaded push rod 2 13 clockwise or counterclockwise, the threaded push rod 2 13 and the clamping frame 11 are forced to move up and down. When the clamping frame 11 moves upward, the limit disc 12 slides to the inside of the upper half of the inclined groove of the folding groove 10, and the limit disc 12 presses against the inclined inner wall of the top of the folding groove 10, forcing the limit frame 2 to flip clockwise; conversely, when the clamping frame 11 moves downward, the limit disc 12 slides to the inside of the lower half of the inclined groove of the folding groove 10, and the limit disc 12 presses against the inclined inner wall of the bottom of the folding groove 10, forcing the limit frame 2 to flip clockwise, thereby facilitating the adjustment of the installation angle of the limit frame 2 and the arc probe to suit installation in multiple scenarios.

[0030] Working principle:

[0031] When the utility model is in use, first insert the connecting ends of the two sets of arc probes into the corresponding limit grooves 7, and then twist the threaded push rod 8 to pull the vertical plate 6 to move backward along the inner part of the slide groove 5, and the arc probe and the clamping assembly 9 are moved backward at the same time;

[0032] The abutment piece 901 moves backward and gradually approaches the corresponding positioning plate 906, and the beveled end of the abutment piece 901 moves along the bevel of the positioning plate 906 and is pressed to move toward the limiting groove 7. The two sets of abutments 901 in the same row approach each other until the two sets of corresponding semicircular grooves 905 overlap and jointly clamp the end of the arc probe. Then, the vertical plate 6 can be pulled backward to limit the arc probe.

[0033] After the probe is limited, the installation angle of the probe is adjusted in time according to the actual required searchlight angle, and the threaded push rod 2 13 is rotated clockwise or counterclockwise to force the threaded push rod 2 13 and the clamping frame 11 to move up and down. When the clamping frame 11 moves upward, the limiting disc 12 slides to the inside of the upper half of the inclined groove of the folding groove 10, and the limiting disc 12 presses the inclined inner wall of the top of the folding groove 10, forcing the limiting frame 2 to flip clockwise; conversely, when the clamping frame 11 moves downward, the limiting disc 12 slides to the inside of the lower half of the inclined groove of the folding groove 10, and the limiting disc 12 presses the inclined inner wall of the bottom of the folding groove 10, forcing the limiting frame 2 to flip clockwise, thereby facilitating the adjustment of the installation angle of the limiting frame 2 and the arc probe;

[0034] When the probe is disassembled, the vertical plate 6, the arc probe and its clamping assembly 9 move forward by rotating in the opposite direction. The abutment 901 loses the pressure of the positioning plate 906 and quickly resets under the rebound force of the spring damping shock absorber 904, thereby losing the clamping of the arc probe, thereby improving the disassembly and assembly efficiency of the arc probe.
