Description

Technical Field

[0001] The invention relates to a tension-type throwing-hanging power transmission personal safety line with a positioning function, belonging to the field of power transmission safety lines. Background Art

[0002] The current incidence of injuries caused by induced electrocution has heightened the need for on-site anti-induced electrocution measures. Existing personal safety cords for power transmission lines lack positioning capabilities. However, transmission line maintenance operations are numerous and widespread, making them difficult to manage. This creates the risk of workers not installing or forgetting to remove their personal safety cords, creating the risk of electric shock and short circuits.

[0003] Furthermore, traditional personal safety cable clamps are designed to open by collision, but the internal latches of the clamps are difficult to dislodge due to insufficient impact force. This requires operators to attempt multiple times, resulting in low installation efficiency. Summary of the Invention

[0004] According to the problem described in the background, the problem to be solved by the present invention is: to provide a tension-type hanging power transmission personal safety line with a positioning function, which realizes efficient hanging and removal through a special wire clamp clamping device, and sets up a satellite positioning module to ensure that "it must be installed when it should be installed and it must be removed when it should be removed", thereby solving the above-mentioned problems of not installing or forgetting to remove the personal security line and low installation efficiency.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tension-type hanging power transmission personal safety line with a positioning function is provided, comprising a grounding wire, a grounding wire clamp, a left wire clamp, a right wire clamp, a wire clamp clamping device, a stopper, a latch connection port, a left connecting block, a right connecting block, a torsion spring, a left outward expansion plate, a right outward expansion plate, a satellite positioning block, a turning plate and a rotating rod, a left connecting block and a right connecting block are respectively installed at the middle position of the opposite sides of the left wire clamp and the right wire clamp, the left connecting block and the right connecting block are connected by a rotating rod, a torsion spring is installed on the rotating rod, and the two ends of the torsion spring contact the left wire clamp. On the clamp and the right wire clamp, an arc-shaped clamping opening is opened on the upper part of the opposite side of the left wire clamp and the right wire clamp, a stop opening is opened between the arc-shaped clamping opening of the left wire clamp and the left connecting block, a locking latch connection opening is opened between the arc-shaped clamping opening of the right wire clamp and the right connecting block, the left outer expansion plate and the right outer expansion plate are installed on the lower outer side of the left wire clamp and the right wire clamp respectively, a satellite positioning block is installed on the upper outer side of the left wire clamp, and a turning plate is installed on the upper outer side of the right wire clamp, the grounding wire is connected to the middle part of the outer side of the right wire clamp, the grounding wire is connected to the grounding wire clamp, and the wire clamp clamping device is installed on the stop opening, the locking latch connection opening, the left outer expansion plate and the right outer expansion plate.

[0006] Preferably, the wire clamp clamping device includes a blocking rod, a positioning latch, a rotating rod, a small spring, a steering pulley, an auxiliary rope loop 1, an auxiliary rope loop 2, auxiliary rope 2 and auxiliary rope 1. The blocking rod is installed in the blocking port, and the positioning latch is rotatably connected to the positioning latch connection port through the tail fixed rotating rod. The lower end of the positioning latch is connected with a small spring, and the other end of the small spring is connected to the lower end surface of the positioning latch connection port. The steering pulley is installed on the outside of the left outer expansion plate, and the auxiliary rope loop 1 and the auxiliary rope loop 2 are installed on the outside of the right outer expansion plate. At the same time, the auxiliary rope loop 1 is above the auxiliary rope loop 2, and the auxiliary rope 2 is fixed on the auxiliary rope loop 2 and passes through the right outer expansion plate, then through the left outer expansion plate, and then through the left outer expansion plate through the steering pulley and then through the right outer expansion plate, and finally through the turning plate. The auxiliary rope 1 is fixed on the auxiliary rope loop 1 and passes through the turning plate.

[0007] Preferably, the left wire clamp and the right wire clamp are made of high-strength aluminum alloy and are die-cast in one step.

[0008] Preferably, the satellite positioning block includes a positioning engine module, a long-range wireless communication module, a control module and a power supply module.

[0009] The beneficial effects of the present invention are:

[0010] 1. The wire clamp clamping device changes the traditional impact type to a double-rope tension type. During installation, the left and right wire clamps are clamped to the conductors by auxiliary rope 1. During disassembly, the left and right wire clamps are pulled apart by auxiliary rope 2, separating them from the conductors, thus solving the previous problem of low installation efficiency.

[0011] 2. The set satellite positioning block can transmit positioning information to the mobile terminal for management and control, ensuring that "what needs to be installed must be installed, and what needs to be removed must be removed", and ensuring the personal safety of power line maintenance workers.

[0012] 3. Change the opening direction of the grounding wire clamp, and design the traditional "A" type wire clamp of the power transmission personal insurance line into a "V" type wire clamp. Change the original vertical downward clamping of the wire to hooking the wire from the bottom up and lock the wire with the wire clamp clamping device. This eliminates the problem that the internal latch of the wire clamp is difficult to knock out due to insufficient impact force during collision, and the operator needs to try multiple times.

[0013] 4. The wire clamp is made of high-strength aluminum alloy and is formed by one-step die-casting process, which ensures strength while reducing weight. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The embodiments of the present invention are further described below with reference to the accompanying drawings:

[0018] Example 1

[0019] like Figure 1 As shown, the present invention provides a tension-type hanging power transmission personal safety line with a positioning function, including a grounding wire 15, a grounding wire clamp 16, a left wire clamp 1, a right wire clamp 2, a wire clamp clamping device, a stopper 3, a latch connection port 43, a left connecting block 5, a right connecting block 6, a torsion spring 7, a left outward expansion plate 8, a right outward expansion plate 9, a satellite positioning block 17, a turning plate 18 and a rotating rod 19. The left connecting block 5 and the right connecting block 6 are respectively installed at the middle position of the opposite sides of the left wire clamp 1 and the right wire clamp 2. The left connecting block 5 and the right connecting block 6 are connected by a rotating rod 19. The rotating rod 19 is equipped with a torsion spring 7. At the same time, the two ends of the torsion spring 7 are in contact with the left wire clamp 1 and the right wire clamp 2. On the upper part, an arc-shaped clamp is provided at the upper part of the opposite sides of the left wire clamp 1 and the right wire clamp 2, a stopper 3 is provided between the arc-shaped clamp of the left wire clamp 1 and the left connecting block 5, and a latch connection port 43 is provided between the arc-shaped clamp of the right wire clamp 2 and the right connecting block 6. The left outer expansion plate 8 and the right outer expansion plate 9 are respectively installed on the lower outer parts of the left wire clamp 1 and the right wire clamp 2. A satellite positioning block 17 is installed on the upper outer part of the left wire clamp 1, and a turning plate 18 is installed on the upper outer part of the right wire clamp 2. The grounding wire 15 is connected to the middle part of the outer side of the right wire clamp 2, and the grounding wire 15 is connected to the grounding wire clamp 16. The wire clamp clamping device is installed on the stopper 3, the latch connection port 43, the left outer expansion plate 8 and the right outer expansion plate 9.

[0020] The arc-shaped clamping opening is set above the left connecting block 5, the right connecting block 6 and the torsion spring 7, the opening direction of the grounding wire clamp is changed, and the "A" type wire clamp of the traditional power transmission personal insurance line is designed as a "V" type wire clamp. The original vertical downward clamping of the wire is changed to hooking the wire from the bottom up and locking the wire with the wire clamp clamping device, eliminating the problem that the internal latch of the wire clamp is difficult to be knocked out due to insufficient impact force during collision, and the operator needs to try multiple times.

[0021] The wire clamping device includes a blocking rod 31, a positioning latch 4, a rotating rod 41, a small spring 42, a steering pulley 10, an auxiliary rope first hanging ring 11, an auxiliary rope second hanging ring 12, an auxiliary rope second 13 and an auxiliary rope first 14. The blocking rod 31 is installed in the blocking port 3, and the positioning latch 4 is rotatably connected to the positioning latch connection port 43 through the tail fixed rotating rod 41. The lower end of the positioning latch 4 is connected to a small spring 42, and the other end of the small spring 42 is connected to the lower end surface of the positioning latch connection port 43. The steering pulley 10 It is installed on the outside of the left outer expansion plate 8, and the auxiliary rope loop 11 and the auxiliary rope loop 2 12 are installed on the outside of the right outer expansion plate 9. At the same time, the auxiliary rope loop 11 is above the auxiliary rope loop 2 12, and the auxiliary rope 2 13 is fixed on the auxiliary rope loop 2 12 and passes through the right outer expansion plate 9, then passes through the left outer expansion plate 8, passes through the left outer expansion plate 8 again through the steering pulley 10, and then passes through the right outer expansion plate 9, and finally passes through the turning plate 18. The auxiliary rope 14 is fixed on the auxiliary rope loop 11 and passes through the turning plate 18.

[0022] When in use, first separate the left wire clamp 1 and the right wire clamp 2 by clamping them on the baffle 31 through the latch 4, and then pull the auxiliary rope 14. Because of the presence of the auxiliary rope hanging loop 11 and the turning plate 18, when the auxiliary rope 14 pulls the safety wire clamp, the safety wire clamp is upward, and the openings of the left wire clamp 1 and the right wire clamp 2 are upward. At this time, align the arc-shaped clamping opening with the wire, and then tighten the auxiliary rope 14. The latch 4 no longer clamps the baffle 31, so that the left wire clamp 1 and the right wire clamp 2 clamp the wire through the torsion spring 7. When recovering, pull the auxiliary rope 2 13, because the auxiliary rope 2 13 passes through the steering pulley 10 to connect the left wire clamp 1 and the right wire clamp 2 through the left outer expansion plate 8 and the right outer expansion plate 9, and one end is tied to the auxiliary rope 2 hanging ring 12 and passes through the turning plate 18, so after tightening the auxiliary rope 2 13, the left wire clamp 1 and the right wire clamp 2 can be separated. At this time, due to the action of the small spring 42, the locking latch 4 is bounced up and returned to the blocking rod 31 to be stuck, so that the safety wire clamp falls off from the wire, completing the recovery of the wire clamp.

[0023] The left wire clamp 1 and the right wire clamp 2 are made of high-strength aluminum alloy and are die-cast in one step, which ensures strength while reducing weight and alleviating the burden on operators.

[0024] The satellite positioning block 17 includes a positioning engine module, a long-range wireless communication module, a control module and a power supply module.

[0025] The positioning engine module uses the L76K module for positioning. The L76K module is a single-frequency, multi-constellation GNSS positioning module that integrates a high-performance, high-reliability positioning engine. It can provide fast and accurate GNSS positioning and supports GPS-L1 C / A, Beidou B1I, GLONASS, QZSS and other constellation positioning. To better obtain positioning information, an active Beidou\GPS ceramic antenna is selected.

[0026] The BC28-CNS module is used for long-range wireless communication with the backend system. This high-performance, low-power NB-IoT module communicates with network operators' infrastructure using the NB-IoT radio communication protocols (3GPP Rel-13 and Rel-14). The module is a surface-mount module with a small size and compact package, making it easy to embed in product applications and meeting the needs of most IoT applications.

[0027] The control module uses the STM32L051 chip, which communicates with the L76K module and the BC28-CNS module via the USART serial port. After acquiring positioning information, it sends this information to the BC28-CNS module via AT commands. The BC28-CNS module then sends a command containing the positioning information, device ID, and other information to the backend terminal. Based on the received command, the backend terminal displays the location of the cable clamp on a map in real time, facilitating remote control of the operator.

[0028] The power supply system uses a lithium-ion polymer battery and a universal Type-C connector for charging. A charging protection circuit is designed to trickle charge the battery when the battery power is low. When the battery voltage reaches 2.9V, the battery is charged at a maximum current of 1A. Charging stops when the battery float voltage reaches 4.2V, extending battery life. The circuit is designed with two charging indicators: red when charging and blue when fully charged, making it easy to check the charging status.
