In the traditional commissioning and maintenance process, operators usually use screwdrivers to disconnect and connect a large number of densely arranged terminal blocks when commissioning and repairing equipment in the system. In this process, operators are prone to visual fatigue, resulting in wrong disconnection and wrong connection of terminal blocks, which will leave safety hazards and seriously threaten the safety of the power system.

[0003] In order to solve the above problems, the prior art uses an insulating plate and an insulating solid column to prevent the occurrence of the problem of wrong removal and wrong connection of terminal strips due to visual fatigue of the operator.

[0054] Embodiment 1

[0055] like Figure 1 As shown, the present application provides a laser-assisted positioning device, including: a mounting bracket A and a laser emitter B; the mounting bracket A has a first connecting part 1 and a second connecting part 2, the second connecting part 2 has a first connecting end 21 and a second connecting end 22, and the second connecting part 2 is used to connect with a screwdriver C; the laser emitter B is rotatably connected to the first connecting part 1, and the emitting end of the laser emitter B can emit a linear laser; wherein the first connecting end 21 is used to connect to the handle of the screwdriver C, and the second connecting end 22 is used to connect to the shank of the screwdriver C.

[0056] Specifically, the specific shape of the mounting bracket A is not limited. It can be a special-shaped rod with multiple connection positions, or it can be a bracket formed by splicing multiple rods. It can be ensured that the mounting bracket A has a first connection part 1 and a second connection part 2, and can meet the positional relationship and installation requirements of other components on the laser-assisted positioning device.

[0057] The first connection part 1 can be a slot or a sleeve. The specific form of the first connection part 1 is not limited, and it can carry and fix the laser emitter B. The rotational connection between the laser emitter B and the first connection part 1 can be achieved through the cooperation of the bearing and the shaft, or through the universal ball and the spherical support. The specific rotational connection is not limited, and the laser emitter B can be rotated relative to the mounting bracket A, so that the position of the laser can be adjusted by rotation.

[0058] The second connecting part 2 can be a bracket with two connecting ends, or a connecting member with two connecting ends, and its specific form is not limited. The first connecting end 21 can be a clamping member with a clamping function, which clamps the handle of the screwdriver C to achieve the connection between the first connecting end 21 and the handle of the screwdriver C, or it can be a tightening rope loop, which is set on the handle of the screwdriver C and tightened to achieve the connection. The specific form and connection method of the first connecting end 21 are not limited, and the first connecting end 21 can be stably connected to the handle of the screwdriver C during the work process without loosening or separation, and can be disassembled after the work is completed. The second connecting end 22 can be a magnet, which is sucked on the shank of the screwdriver C to achieve the connection, or it can be a clamping member with a clamping function, which clamps the shank of the screwdriver C to achieve the connection between the second connecting end 22 and the shank. The specific type of the second connecting end 22 and the connection method of the second connecting end 22 are not specifically limited, and a stable connection can be achieved during the work process, and it can be disassembled after the work is completed.

[0059] Compared with the prior art, the laser-assisted positioning device provided in the first aspect of the present application includes: a mounting bracket A and a laser emitter B, wherein the mounting bracket A has a first connection part 1 and a second connection part 2, and the laser emitter B is rotatably connected to the first connection part 1, and the second connection part 2 has a first connection end 21 and a second connection end 22, wherein the first connection end 21 is connected to the handle of the screwdriver C, and the second end is connected to the shank of the screwdriver C. The emitting end of the laser emitter B emits laser light, and the laser forms a horizontal indication line at the terminal block interface and the nearby interface that need to be disassembled and connected. The indication line can prevent visual fatigue of the operator during the operation, resulting in wrong disassembly and wrong connection of the terminal block, so that the operator can correctly disassemble and connect the terminal block and the terminal, which can ensure the safety of the operator and the safety of the equipment, while improving the operation speed of the operator and reducing the risk of safety accidents in the power system.

[0060] like Figure 2 As shown, in some embodiments, the laser-assisted positioning device also includes: a fixed sleeve 3, which is in the shape of a long cylinder, a spherical mounting seat 31 is provided on the side wall of the fixed sleeve 3, and the laser emitter B is penetrated into the interior of the fixed sleeve 3; the first connecting part 1 includes: a spherical structure 11, the spherical structure 11 is installed in cooperation with the spherical mounting seat 31, so that the fixed sleeve 3 can rotate relative to the mounting bracket A.

[0061] First connection part 1 fixing sleeve 3 spherical structure 11 fixing sleeve 3 fixing sleeve 3 spherical mounting seat 31 laser emitter B fixing sleeve 3 spherical structure 11 mounting bracket A spherical structure 11 spherical mounting seat 31 fixing sleeve 3 mounting bracket A Specifically, the long cylindrical fixing sleeve 3 can match the shape of the laser emitter B, fit with the laser emitter B, and achieve a stable fixed connection. The spherical mounting seat 31 provided on the fixing sleeve 3 is installed and matched with the spherical structure 11 provided on the mounting bracket A, so that the fixing sleeve 3 can rotate relative to the mounting bracket A, thereby adjusting the angle of the laser emitted by the emitting end of the laser emitter B, and adjusting the laser to the blade of the screwdriver C, thereby achieving the function of auxiliary positioning.

[0062] It should be noted that the rotation between the spherical structure 11 and the spherical mounting seat 31 has a certain damping, and a certain force is required to make the fixing sleeve 3 rotate relative to the mounting bracket A. The specific shape of the mounting bracket A is not limited, and it only needs to have an accommodating space that can accommodate the spherical structure 11.

[0063] like Figure 3 As shown, in some embodiments, the spherical mounting seat 31 is cylindrical, with a spherical accommodating space provided inside, and the spherical structure 11 is arranged in the spherical accommodating space; the spherical mounting seat 31 also includes: a locking cover 32, a circular opening is provided on the locking cover 32, and an arc structure that can fit with the spherical structure 11 is provided on the edge of the opening, and the locking cover 32 is connected to the outside of the spherical mounting seat 31 by a thread; wherein, by loosening or tightening the locking cover 32, the arc structure presses against or releases the spherical structure 11.

[0064] Specifically, the cylindrical shape of the spherical mounting seat 31 can make the thread processing process of the locking cover 32 more concise and simple in structure. The arc structure is arranged on the inner side of the locking cover 32 close to the spherical structure 11. The specific size of the arc structure is selected according to the area of ​​the arc at the spherical structure 11 in contact. It is not specifically limited and can fit the spherical structure 11. When the locking cover 32 is tightened, the arc structure abuts against the spherical structure 11 to prevent the rotation of the spherical structure 11. When the locking cover 32 is loosened, the arc structure releases the abutment of the spherical structure 11, so that the spherical structure 11 can rotate normally. The above process is used to limit the spherical structure 11 to prevent the pre-adjusted laser from being offset due to the accidental contact with the fixing sleeve 3 during the working process.

[0065] In some embodiments, a threaded hole is provided on the side wall of the fixing sleeve 3; the fixing sleeve 3 also includes: a locking screw, the locking screw is connected to the threaded hole, and when the locking screw is tightened or loosened, one end of the locking screw presses against or releases the laser emitter B.

[0066] Specifically, the locking screw is screwed into the threaded hole provided on the side wall of the fixing sleeve 3 to achieve the abutment against the laser emitter B. When the locking screw is tightened, the locking screw abuts against the laser emitter B, making it difficult for the laser emitter B to separate from the fixing sleeve 3, effectively reducing the probability of the laser emitter B and the fixing sleeve 3 falling off due to accidental touch. When the locking screw is loosened, the locking screw releases the abutment against the laser emitter B, and the laser emitter B can be disassembled. At the same time, a protective member that can fit the side wall of the laser emitter B can be provided at one end of the screw abutting against the laser emitter B to prevent damage to the laser emitter B during the abutment.

[0067] like Figure 4 As shown, in some embodiments, the first connection end 21 is a clamping component 211, which can clamp the handle of the screwdriver C; the second connection end 22 includes a first magnetic holding component 212, which can hold the shank of the screwdriver C.

[0068] Specifically, the first connection end 21 and the second connection end 22 of the first connection part 1 can cooperate with the clamping component 211 and the first magnetic holding component 212 respectively to achieve rapid holding and adjustment. The first magnetic holding component 212 can adopt a magnet with magnetic force. The magnet can hold the metal screwdriver C shank to achieve rapid connection between the laser-assisted positioning device and the screwdriver C. At the same time, the clamping component 211 clamps the handle of the screwdriver C to achieve rapid adjustment of the laser-assisted positioning device so that the laser emitter B can roughly reach the required working position. Subsequently, the laser emitter B is fine-tuned through the rotational connection between the laser emitter B and the mounting bracket A to achieve that the laser emitted by the laser emitter B is irradiated on the tip of the screwdriver C to assist the operator in positioning.

[0069] like Figure 4 As shown, in some embodiments, the clamping assembly 211 has a first clamping member 2111 and a second clamping member 2112, the first clamping member 2111 and the second clamping member 2112 are closed to form a clamping area, and a plurality of mounting holes whose length directions are perpendicular to the side walls are evenly arranged on the side walls corresponding to the first clamping member 2111 and the second clamping member 2112 in the clamping area;

[0070] The clamping portion also includes: a plurality of long first push-up members 2113 and a plurality of first elastic elements; the plurality of first push-up members 2113 are slidably arranged in the mounting holes, and the number of the first push-up members 2113 is equal to the number of the mounting holes; one end of the plurality of first elastic elements is respectively connected to the plurality of first push-up members 2113, and the other end is respectively connected to the first clamping member 2111 and the second clamping member 2112, and the number of the first elastic elements is equal to the number of the first push-up members 2113; wherein, when the clamping assembly 211 clamps the handle of the screwdriver C, the first push-up member 2113 presses against the handle and compresses the first elastic element, and when the clamping assembly 211 releases the clamping, the first elastic element resets the first push-up member 2113.

[0071] Specifically, the first clamping member 2111 and the second clamping member 2112 are closed to form a clamping area for the handle of the screwdriver C. The arrangement method and number of the mounting holes are not specifically limited. Multiple mounting holes can be arranged side by side and spaced apart in the center of the side walls corresponding to the first clamping member 2111 and the second clamping member 2112 in the clamping area, or multiple rows of mounting holes can be arranged. The long strip-shaped first abutting member 2113 can be a cylinder or a cuboid. The specific shape of the first abutting member 2113 is not limited and is selected according to the shape of the mounting hole. In this embodiment, a cylindrical first abutting member 2113 can be selected.

[0072] The first elastic element can be a compression spring, and the position and connection relationship between the first elastic element and the plurality of mounting holes and the first push piece 2113 can be that the first elastic element is first placed in the mounting hole, and then the first push piece 2113 is placed in the mounting hole, and at the same time, a limit is set for the first push piece 2113 to prevent the first push piece 2113 from being separated from the mounting hole, and the specific method of the limit is not limited. When the clamping assembly 211 clamps the handle of the screwdriver C, the first push piece 2113 will push against the handle, and at the same time, the clamping assembly 211 is used to clamp the screwdriver C from both sides of the screwdriver C, so the screwdriver C is relatively stationary. At this time, the first push piece 2113 will move into the mounting hole along the length direction of the mounting hole due to the clamping action of the first clamping member 2111 or the second clamping member 2112 on the handle of the screwdriver C, and compress the first elastic element. When the first clamping member 2111 and the second clamping member 2112 are completely closed, the movement stops, and the multiple first abutting members 2113 on the first clamping member 2111 and the second clamping member 2112 can clamp the handle of the screwdriver on both sides of the handle C due to the elastic force of the first elastic element.

[0073] When the work is finished, the closed state of the first clamping member 2111 and the second clamping member 2112 is released, and the screwdriver C is taken out. Since the multiple first abutting members 2113 no longer abut the tool handle, the multiple first elastic elements will release the elastic force, so that the multiple first abutting members 2113 will be reset.

[0074] In this embodiment, since the first push piece 2113 has a certain stroke in the mounting hole, the handles of screwdrivers C of different sizes make the first push piece 2113 enter the mounting hole to different degrees, and the compression amount of the first elastic element is also different, thereby achieving clamping of handles of different sizes.

[0075] like Figure 4 As shown, in some embodiments, the clamping assembly 211 includes: a fixing portion 2114, a second abutting member 2115 and two connecting rods 2117; a connecting hole is provided in the middle of the fixing portion 2114; the first clamping member 2111 and the second clamping member 2112 are both the same bending members, the first clamping member 2111 and the second clamping member 2112 are symmetrically arranged on both sides of the connecting hole, and one end of the first clamping member 2111 and the second clamping member 2112 are hinged to the fixing portion 2114; the second abutting member 2115 is provided with a sliding rod 2116, and the sliding rod 2116 penetrates into the connecting rod. The connecting hole enables the second abutting piece 2115 to slide along the length direction of the connecting hole; one end of the two connecting rods 2117 is hinged to the first clamping piece 2111 and the second clamping piece 2112 near the middle respectively, and the other ends of the two connecting rods 2117 are symmetrically arranged on both sides of the sliding rod 2116 of the second abutting piece 2115, and are hinged to the second abutting piece 2115; wherein, when the second abutting piece 2115 abuts against the knife handle, the second abutting piece 2115 moves toward the direction close to the mounting hole, and drives the first clamping piece 2111 and the second clamping piece 2112 to close.

[0076] Specifically, the fixing part 2114, the first clamping member 2111 and the second clamping member 2112 form a clamping structure. The fixing part 2114 can be a connecting block or a connecting member with a hinged connection position, which is not specifically limited. The first clamping member 2111 and the second clamping member 2112 are the same bending rods, and the bending angle and the number of bending times are not specifically limited. The handle of the screwdriver C can be clamped. The sliding rod 2116 provided on the second abutting member 2115 extends into the connecting hole provided in the middle of the fixing part 2114. The second abutting member 2115 can slide along the length direction of the connecting hole according to the sliding connection between the sliding rod 2116 and the connecting hole. When the second abutting member 2115 abuts against the handle of the screwdriver C, the operator needs to apply a certain force to the second abutting member 2115 to move toward the inside of the connecting hole. At the same time, the second abutting member 2115 pulls the first clamping member 2111 and the second clamping member 2112 to close through the two connecting rods 2117 to achieve the clamping action of the clamping assembly 211. The solution of this embodiment can achieve automatic clamping of the clamping assembly 211, has the advantages of simple operation and fast clamping speed, and makes the installation of the laser-assisted positioning device more convenient.

[0077] In some embodiments, the clamping assembly 211 further includes: two magnets, which are respectively disposed at the other ends of the first clamping member 2111 and the second clamping member 2112. When the first clamping member 2111 and the second clamping member 2112 are closed, the two magnets are attracted to each other.

[0078] Specifically, the two magnets can be connected to the other ends of the first clamp 2111 and the second clamp 2112 respectively by screws, or by strong glue. The specific connection method is not limited. During operation, the two magnets are not separated from the first clamp 2111 and the second clamp 2112. When the first clamp 2111 and the second clamp 2112 are closed, the two magnets can be automatically adsorbed to keep the first clamp 2111 and the second clamp 2112 in a closed state. When the closed state needs to be released, it can be operated manually. The structure is simple and easy to use, and the installation of the laser-assisted positioning device is more convenient.

[0079] In some embodiments, the clamping assembly 211 also includes: a second elastic element, which is sleeved on the sliding rod 2116, one end of the second elastic element abuts the fixed portion 2114, and the other end abuts the second abutting member 2115. When the first clamping member 2111 and the second clamping member 2112 are released from closing, the second elastic element drives the second abutting member 2115 to reset.

[0080] Specifically, the second elastic element can be a compression spring, and the second elastic element is sleeved on the slide bar 2116. When the second abutting member 2115 abuts against the handle of the screwdriver C, the operator provides a certain force, so that the second abutting member 2115 and the fixing portion 2114 move relative to each other, compressing the second elastic element, so that the second elastic element stores energy. When the second abutting member 2115 is no longer abutting against the handle of the screwdriver C, the second elastic element releases the elastic force, pushing the second abutting member 2115 to reset, and driving the first clamping member 2111 and the second clamping member 2112 to recover from the closed state to the open state without clamping the handle of the screwdriver C. The second elastic element realizes the automatic reset of the second abutting member 2115, and then realizes the automatic opening of the clamping assembly 211 when the clamping ends, making the removal of the laser-assisted positioning device more convenient.
