[0001] The present invention relates to the technical field of live working equipment, and particularly relates to a bypass operation fixing device and a method for building a bypass system. Background Art

[0002] With the increase in the user's electricity demand, live working, as the most direct and effective means to improve power supply reliability, can bring more social benefits and users have "zero perception" during the operation. In live working with load, the commonly used method is bypass drainage, that is, an insulating drainage wire is used to construct a small bypass system, and then the equipment to be repaired is isolated to achieve live repair work without power interruption.

[0003] A wire of the same wire diameter can be used as the current-carrying channel for constructing the bypass system, that is, the drainage wire. The specific method is as follows: Two insulating boom trucks carry out operations simultaneously, insulate and cover the cross arm and other energized conductors, fix the middle of the drainage wire on the insulator, and the two insulating boom trucks carry out operations simultaneously to connect the drainage wire to the main line at the same time to complete the construction of the bypass system.

[0004] However, by using this method to build the bypass system, two insulating boom trucks are required to carry out live working, and the efficiency is not high. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to provide a bypass operation fixing device and a method for building a bypass system, reduce the use of insulating boom trucks, and improve the operation efficiency.

[0008] The beneficial effects of the present invention are as follows: A bypass operation fixing device and a bypass system construction method of the present invention can complete the construction and demolition operations of the bypass system only by using one insulated boom truck through the innovative bypass operation fixing device and construction method.

[0010] To describe in detail the technical content, achieved objectives and effects of the present invention, the following is described in conjunction with the embodiments and with reference to the drawings.

[0011] Please refer to Figures 1-3 , a bypass operation fixing device, including a main wire clamp, a lead sleeve and a support rod; The main wire clamp and the lead sleeve are insulated and fixedly spaced apart by the support rod; The main wire clamp includes a fixed part and a movable part, and the movable part can move relative to the fixed part to form a clamping structure; The lead sleeve is provided with a lead fixing device.

[0012] As can be seen from the above description, the beneficial effects of the present invention are as follows: A bypass operation fixing device of the present invention mainly consists of a main line clamp, a lead sleeve and a support rod. The main line clamp and the lead sleeve are insulated and fixedly spaced apart by the support rod. This structural design enables the device to ensure that the main line clamp is fixed on the main conductor during use, and at the same time, the insulation between the lead sleeve and the main line clamp can be achieved, facilitating the insertion of one end of the bypass wire into the lead sleeve for insulating fixation with the main conductor, providing convenience for the construction of the bypass system. Moreover, this design can effectively avoid current conduction during the operation process, ensuring the safety of the operators; it can be universal for different line arrangements (such as triangular arrangement, vertical arrangement), has wide applicability, and meets the requirements of various operation scenarios. Compared with the traditional method, there is no need for complex adjustment or equipment replacement due to different line arrangements; and this bypass operation fixing device, in cooperation with the corresponding construction method, only requires one insulating boom truck to complete the operation, directly reducing the equipment investment cost, avoiding the complex coordination process during the cooperative operation of two vehicles, and effectively improving the operation efficiency.

[0013] Further, the fixing part includes an upper clamping part and a first connecting rod; The movable part includes a lower clamping part, a second connecting rod and a pull rod; The first connecting rod is connected to one side of the upper clamping part; One end of the pull rod is connected to the first connecting rod through a rotating shaft, one end of the second connecting rod is connected to the rod body of the pull rod, and the other end is connected to the lower clamping part; When the pull rod rotates vertically downward through the rotating shaft, the top of the lower clamping part abuts against the upper clamping part.

[0014] As can be seen from the above description, the fixing part includes an upper clamping part and a first connecting rod; the movable part includes a lower clamping part, a second connecting rod and a pull rod. The first connecting rod is connected to one side of the upper clamping part, one end of the pull rod is connected to the first connecting rod through a rotating shaft, one end of the second connecting rod is connected to the rod body of the pull rod, and the other end is connected to the lower clamping part. When the pull rod rotates vertically downward through the rotating shaft, the top of the lower clamping part abuts against the upper clamping part, and at this time, a stable clamping state is formed, which can tightly clamp the wire.

[0015] Further, main line grooves are provided at the bottom of the upper clamping part and the top of the lower clamping part; When the top of the lower clamping part abuts against the bottom of the upper clamping part, the two main line grooves form a receiving space for the main line.

[0016] From the above description, it can be seen that main line grooves are provided at the bottom of the upper clamping part and the top of the lower clamping part. When the two main line grooves at the top of the lower clamping part collide with the bottom of the upper clamping part, a storage space for the main line will be formed. Such a design can better adapt to the shape of the conductor and improve the stability and reliability of clamping.

[0017] Furthermore, a stepped structure is provided at the bottom of the upper clamping portion; When the top of the lower clamping part abuts against the bottom of the upper clamping part, the stepped structure abuts against the top and side walls of the lower clamping part.

[0018] From the above description, it can be seen that a stepped structure is provided at the bottom of the upper clamping part. When the top of the lower clamping part contacts the bottom of the upper clamping part, the stepped structure contacts and cooperates with the top and side wall of the lower clamping part, further enhancing the firmness of the clamping and preventing the wire from loosening during operation.

[0019] Furthermore, the pull rod is connected with a pull ring at one end away from the rotating shaft.

[0020] From the above description, it can be seen that a pull ring is connected to the end of the pull rod away from the rotating shaft. The design of the pull ring is convenient for operators to operate. By pulling the pull ring, the rotation of the pull rod can be easily controlled to achieve the opening and closing of the main line clamp.

[0021] Further, the lead fixing device is a fixing bolt; The lead sleeve is provided with a threaded hole, and the fixing bolt cooperates with the threaded hole, so that the size of the portion of the fixing bolt entering into the lead sleeve can be adjusted.

[0022] As can be seen from the above description, the fixing bolt cooperates with the threaded hole to adjust the size of the portion of the fixing bolt that enters the lead sleeve. In this way, the position of the fixing bolt can be flexibly adjusted according to the different specifications of the lead wire to ensure that the lead wire is firmly fixed in the lead sleeve.

[0023] Further, the lead fixing device is arranged at one end of the lead sleeve; One end of the lead sleeve away from the lead fixing device is inclined downward.

[0024] From the above description, it can be seen that the lead fixing device is arranged at one end of the lead sleeve, and the end of the lead sleeve away from the lead fixing device is tilted downward. This design helps to utilize gravity to make the drainage wire enter the lead sleeve more smoothly when inserting the drainage wire. At the same time, it can also prevent rainwater and other debris from entering the interior of the lead sleeve and affecting the performance of the equipment.

[0025] Further, it also includes a handle; The handle is fixed and insulated to the lead sleeve.

[0026] As described above, the device further includes a handle, which is fixedly and insulatedly connected to the lead sleeve, facilitating the operator to hold and operate, and the insulated connection ensures the safety of the operator.

[0027] Please refer to Figure 4 , a method for building a bypass system, comprising the steps of: S1. Operate the insulated boom truck to fix the main line clamp of the bypass operation fixing device on the main conductor on either side of the pole tower; The bypass operation fixing device adopts the bypass operation fixing device described above; S2. Insert one end of the bypass lead into the lead sleeve of the bypass operation fixing device to insulatively fix the bypass lead to the main conductor; S3. Operate the insulated boom truck to the position of the cross arm, and fix the middle section of the bypass lead on the cross arm through a post insulator; S4. Operate the insulated boom truck to the side of the pole tower where the bypass operation fixing device is not used, and connect the bypass lead to the main conductor through a wire clamp; S5. Operate the insulated boom truck to the side of the pole tower where the bypass operation fixing device is used, take out the bypass lead from the lead sleeve, and connect it to the main conductor through a wire clamp to complete the construction of the bypass system.

[0028] As can be seen from the above description, the beneficial effects of the present invention are as follows: A method for building a bypass system according to the present invention optimizes the building method based on the innovatively designed device structure, successfully solves many problems existing in the traditional bypass system building method. In practical applications, it can not only reduce the use of insulated boom trucks, lower equipment costs, improve operation efficiency, but also has good versatility and operation convenience, and can effectively ensure the safety and stability of operations.

[0029] Further, before step S1, there is also a step: S0. Operate the insulated boom truck to insulatively shield the cross arm and other energized conductors.

[0030] As can be seen from the above description, operating the insulated boom truck to insulatively shield the cross arm and other energized conductors ensures the safety during the operation process and avoids electric shock accidents.

[0031] A bypass operation fixing device and a method for building a bypass system according to the present invention are mainly applicable to the distribution live working scenario, especially the working scenario that requires building a bypass system for live maintenance without power interruption.

[0032] Please refer to Figures 1 to 3 , Example 1 of the present invention is: A bypass operation fixing device mainly consists of a main line clamp 1, a lead sleeve 2 and a support rod 3.

[0033] The main line clamp 1 is one of the key components of the device. It includes a fixed part and a movable part. The fixed part contains an upper clamping part 11 and a first connecting rod 12. The upper clamping part 11 is in a similar inverted "U" shape structure, and a main line groove for placing the main line is provided at its bottom, which plays an important role when clamping the main line in cooperation with the movable part. The first connecting rod 12 is connected to one side of the upper clamping part 11, providing a support and connection basis for the movement of the movable part.

[0034] The movable part is composed of a lower clamping part 13, a second connecting rod 14 and a pull rod 15. One end of the pull rod 15 is connected to the first connecting rod 12 through a rotating shaft, one end of the second connecting rod 14 is connected to the rod body of the pull rod 15, and the other end is connected to the lower clamping part 13. The shape of the lower clamping part 13 is adapted to that of the upper clamping part 11, and a main line groove is provided at the top. When cooperating with the upper clamping part 11, the two main line grooves jointly form a space for accommodating the main line. The movement of the pull rod 15 can drive the lower clamping part 13 to act. At the end of the pull rod 15 far from the end connected to the first connecting rod 12 through the rotating shaft, a pull ring 16 is connected, which is convenient for the operator to operate. By pulling the pull ring 16, the pull rod 15 can be rotated around the rotating shaft, thereby realizing the opening and closing actions of the lower clamping part 13 and the upper clamping part 11. A stepped structure is provided at the bottom of the upper clamping part 11. When the upper clamping part 11 and the lower clamping part 13 are closed, the top of the lower clamping part 13 abuts against the bottom of the upper clamping part 11, and the stepped structure at the bottom of the upper clamping part 11 abuts and cooperates with the top and side walls of the lower clamping part 13, enhancing the stability of clamping the main line.

[0035] The lead sleeve 2 is used to fix the bypass line, and a lead fixing device 21 is provided on it. In this embodiment, the lead fixing device 21 is a fixing bolt, and a threaded hole cooperating with the fixing bolt is provided on the lead sleeve 2. By rotating the fixing bolt, the size of the part entering the lead sleeve 2 can be adjusted, so as to adapt to different specifications of the bypass line and ensure that the bypass line can be firmly fixed in the lead sleeve 2. The lead fixing device 21 is arranged at one end of the lead sleeve 2, and the end of the lead sleeve 2 far from the lead fixing device 21 is inclined downward. This design helps the insertion of the bypass line, makes the bypass line enter the lead sleeve 2 more smoothly by the action of gravity, and at the same time can prevent sundries such as rainwater from entering.

[0036] The support rod 3 plays a key role in connection and insulation. It insulates and fixes the main line clamp 1 and the lead sleeve 2 at intervals, ensuring the insulation performance between the main line clamp 1 and the lead sleeve 2 during the operation process, preventing current leakage and ensuring the safety of the operator.

[0037] In addition, the device is also equipped with a handle 4, which is fixed and insulated to the lead sleeve 2. The design of the handle 4 is convenient for operators to hold the device. When operating the insulated boom truck to build and dismantle the bypass system, the operator can hold the handle 4 to more accurately control the position and movement of the device. At the same time, the insulated connection effectively ensures the personal safety of the operator.

[0038] Through the above structural design, the preliminary preparation work for the construction of the bypass system can be efficiently and safely implemented during live distribution operations, providing strong support for the subsequent smooth completion of the bypass system construction and the realization of non-stop maintenance operations.

[0039] Please refer to Figure 4 , Embodiment 2 of the present invention is: A bypass system construction method comprises the following steps: S0. Operate the insulated boom truck to insulate and shield the crossarm and other phase-charged parts.

[0040] In this embodiment, the operator operates the insulated boom truck to first insulate and shield the crossarm and other phase-carrying parts. In this process, the insulated boom truck sends the operator to a suitable position, and the operator uses professional insulating shielding materials to carefully cover the crossarm and surrounding phase-carrying parts that may have safety hazards, so as to prevent electric shock accidents in subsequent operations and ensure the personal safety of the operator.

[0041] S1. Operate the insulated boom truck to fix the main line clamp 1 of the bypass operation fixture on the main line on either side of the tower; The bypass operation fixing device adopts a bypass operation fixing device described in the above embodiment 1.

[0042] In this embodiment, the insulated boom truck is operated to move to any side of the pole tower. The operator holds the bypass operation fixture and controls the pull rod 15 of the main line clamp 1 through the pull ring 16, so that the pull rod 15 rotates around the rotating shaft, driving the lower clamping part 13 to move, thereby opening and closing the fixed part and the movable part of the main line clamp 1. After the main line clamp 1 is aligned with the main conductor, the lower clamping part 13 is controlled to move upward until the top of the lower clamping part 13 contacts the upper clamping part 11. At this time, the main line groove at the bottom of the upper clamping part 11 and the main line groove at the top of the lower clamping part 13 jointly form a space for accommodating the main line, and the stepped structure at the bottom of the upper clamping part 11 contacts the top and side wall of the lower clamping part 13, completing the fixation of the main line clamp 1 of the bypass operation fixture on the main conductor.

[0043] S2. Insert one end of the drainage wire into the lead sleeve 2 of the bypass operation fixing device to insulate and fix the drainage wire to the main lead.

[0044] In this embodiment, one end of the drain wire is inserted into the lead sleeve 2 of the bypass operation fixture. According to the specifications of the drain wire, the operator rotates the lead fixture 21 (fixing bolt) to adjust the size of the portion of the lead that enters the lead sleeve 2, so that the fixing bolt is tightly against the drain wire, thereby achieving insulation and fixation of the drain wire and the main conductor, and ensuring that the current will not leak during the subsequent operation.

[0045] S3. Operate the insulating boom truck to the cross arm position, and fix the middle section of the drain wire on the cross arm through a column insulator.

[0046] In this embodiment, the insulated boom truck is operated to the cross arm position, and the operator fixes the middle section of the drain line on the cross arm through the column insulator. This step effectively fixes the position of the drain line, prevents it from shaking during subsequent operations, and ensures the stability of the bypass system.

[0047] S4. Operate the insulated boom truck to the side of the tower where the bypass operation fixture is not used, and connect the drainage line and the main line through a wire clamp.

[0048] In this embodiment, the insulated boom truck is operated to the side of the tower where the bypass operation fixture is not used, and the operator connects the drainage line to the main line through the wire clamp. At this time, the current begins to pass through the connected part of the drainage line, preparing for the subsequent completion of the bypass system construction.

[0049] S5. Operate the insulating boom truck to the side of the tower using the bypass operation fixture, take the drain wire out of the drain sleeve 2, and connect it to the main drain wire through a wire clamp to complete the bypass system construction.

[0050] In this embodiment, the insulating boom truck is operated to the side of the tower using the bypass operation fixture, and the operator takes out the lead wire from the lead wire sleeve 2 and connects it to the main wire through the wire clamp. At this point, the bypass system is completed. At this point, the faulty line can be safely isolated and repaired without affecting the normal power supply of the entire power supply system to users.

[0051] In addition, in this embodiment, after the line maintenance is completed, the steps for dismantling the bypass system are opposite to those for construction. First, operate the insulating boom truck to the side where the bypass operation fixing device is used, open the drain wire clamp connected to the main conductor, and reinsert the drain wire into the lead sleeve 2; then operate the insulating boom truck to the other side to remove the connection between the drain wire and the main conductor; then operate the insulating boom truck to the cross arm position to remove the fixation of the drain wire and the column insulator; then operate the insulating boom truck back to the position of fixing the main wire clamp 1, open the main wire clamp 1, and remove the device from the conductor; finally, operate the insulating boom truck to remove the insulation shielding of the cross arm and other phase live bodies to complete the dismantling of the entire bypass system.

[0052] In summary, the bypass operation fixing device and the method for building a bypass system provided by the present invention, through the innovative design of the device structure and the optimization of the building method, successfully solve many problems existing in the traditional bypass system building method. In practical applications, it can not only reduce the use of insulated boom trucks, lower equipment costs, improve operation efficiency, but also has good versatility and operation convenience, and can effectively ensure the safety and stability of operations.
