Description

Technical Field

[0001] This utility model relates to the technical field of grounding and static electricity conduction devices, and more specifically, to a static electricity conduction wire device. Background Technology

[0002] The principle of the static discharge device is to connect the static discharge terminal on the vehicle or container, the static discharge track on the vehicle chassis, and the ground to form a closed loop, thereby conducting the static electricity on the facilities and equipment to the ground. The purpose is to eliminate the static electricity generated by the friction between the flammable and explosive liquids or gases in the container and the pipe wall during production, loading and unloading, and transportation.

[0003] When refueling an aircraft using an aircraft refueling truck, the electrostatic discharge (ESD) cable installed on the truck must be connected to a designated location on the aircraft to ensure that the truck's electrical potential matches that of the aircraft, preventing discharge due to potential discrepancies. Therefore, it is crucial to ensure that the aircraft refueling truck, ESD cable, and aircraft are interconnected. However, the current testing procedures for ensuring the overall connectivity of the ESD cable are quite cumbersome, and the probability of ESD cable malfunctions is generally high, placing significant pressure on field personnel for long-term maintenance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that place a high burden of long-term maintenance on field personnel for static-dissipating wire devices, and to provide a static-dissipating wire device that reduces the burden of long-term maintenance on field personnel for static-dissipating wire devices.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A static-dissipating wire device is provided, comprising a static-dissipating wire reel, a static-dissipating wire, and a wire clamp, wherein the static-dissipating wire is wound on the static-dissipating wire reel, and both ends of the static-dissipating wire are respectively connected to the static-dissipating wire reel and the wire clamp; it also includes a resistance measuring instrument, the resistance measuring instrument having a first port and a second port for connecting to the wire clamp, the first port being connected to the static-dissipating wire reel.

[0007] This utility model discloses a conductive wire device. In use, the conductive wire reel is installed on an aircraft refueling truck. Pulling the clamp releases the conductive wire wound on the reel, and the clamp is then attached to the aircraft. During refueling, this balances the electrical potential between the refueling truck and the aircraft. After the operation is complete, the clamp is locked at the second port, and a resistance meter measures the overall resistance of the conductive wire reel, conductive wire, clamp, and aircraft refueling truck. When the resistance is normal, there are no abnormalities in the entire device; when the resistance is abnormal, there is a fault in one of these components. By using a resistance meter, one end of which is directly connected to the conductive wire reel, and the other end connected via the clamp, the continuity of the entire conductive wire device can be quickly checked, reducing the long-term maintenance burden on on-site personnel.

[0008] Furthermore, the conductive wire reel includes a rotating shaft and a roller. The roller is sleeved outside the rotating shaft and is rotatably connected to the rotating shaft, and is also electrically connected to the rotating shaft. One end of the roller is connected to the conductive wire, and the other end of the roller is electrically connected to the first port. The conductive wire reel is fixedly connected to the aircraft refueling vehicle via the rotating shaft, and the roller rotates on the rotating shaft to wind up and unwind the conductive wire.

[0009] Furthermore, the conductive wire reel also includes a conductive slip ring, which is disposed on the drum or the rotating shaft, with its two ends electrically connected to the drum and the rotating shaft, respectively. By setting the conductive slip ring, a stable electrical connection between the rotating shaft and the drum is maintained during wire winding and unwinding, ensuring that the aircraft refueling truck and the aircraft are always stably connected. This avoids problems such as high resistance or dust accumulation caused by friction and the accumulation of impurities, reducing the long-term maintenance burden on on-site personnel for the conductive wire device.

[0010] Furthermore, the conductive slip ring includes a stator, a mounting portion, and a rotor portion connected in sequence. The mounting portion is fixedly connected to the roller, the stator is electrically connected to the roller, and the rotor is electrically connected to the rotating shaft. The mounting portion fixes the position of the conductive slip ring, and the stator and rotor portions are electrically connected to the rotating shaft and roller respectively, maintaining a stable electrical connection between the rotating shaft and the roller while rotating.

[0011] Furthermore, the rotating shaft has a countersunk hole, the rotor portion is located within the countersunk hole, the rotor portion is rotatably connected to the rotating shaft, and the rotor portion has a rotor outlet end, which is electrically connected to the rotating shaft. When the conductive slip ring rotates, the conductive slip ring remains within the countersunk hole, thereby maintaining a stable electrical connection between the rotating shaft and the drum during wire winding and unwinding.

[0012] Furthermore, the conductive wire reel also includes an inner shell and an outer shell. The inner shell is detachably connected to the roller and is fitted over the stator portion. The mounting portion engages with the inner shell, and the outer shell is fitted over the inner shell and electrically connected to the roller. The stator portion has a stator output terminal, which is electrically connected to the outer shell. The inner shell and outer shell secure the conductive slip ring and facilitate disassembly and maintenance of the conductive slip ring.

[0013] Furthermore, the mounting part is provided with a mounting hole, and the inner shell is provided with a protrusion, which is inserted into the mounting hole. Inserting the protrusion into the mounting hole facilitates the installation of the conductive slip ring.

[0014] Furthermore, the inner shell and the outer shell are threaded together, ensuring a stable connection between them.

[0015] Furthermore, the conductive wire reel also includes a first reel and a second reel, both with outer diameters larger than the outer diameter of the drum. The first and second reels are fixedly connected to both ends of the drum. One end of the rotating shaft passes through the first reel, and the other end is electrically connected to the second reel. The first measuring line is connected to the first reel, and the conductive wire is connected to the second reel. By providing the first and second reels, the conductive wire wound on the drum is prevented from falling off from both ends of the drum.

[0016] Furthermore, the second reel is equipped with a handle. By rotating the second reel using the handle, it is easy to wind the conductive wire onto the roller.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The present invention provides a static electricity conductive wire device, which, by setting up a resistance measuring instrument, directly connects one end of the resistance measuring instrument to the static electricity conductive wire reel, and the other end of the resistance measuring instrument can be connected to the static electricity conductive wire reel through a wire clamp, can quickly detect whether the entire static electricity conductive wire device is connected, reducing the long-term maintenance burden on on-site personnel.

[0019] 2. The present invention provides a static-conducting wire device that, by setting a conductive slip ring, maintains a stable electrical connection between the rotating shaft and the drum during wire winding and unwinding, ensuring that the aircraft refueling truck and the aircraft are always in a stable conductive state. This avoids the problems of high resistance or dust accumulation caused by friction and the accumulation of impurities, and reduces the long-term maintenance burden on on-site personnel for the static-conducting wire device.

[0027] Example 1

[0028] This embodiment is a first embodiment of a static-conducting wire device, such as... Figure 1 As shown, it includes a conductive wire reel 100, a conductive wire 200, and a wire clamp 300. The conductive wire 200 is wound on the conductive wire reel 100, and its two ends are connected to the conductive wire reel 100 and the wire clamp 300, respectively. It also includes a resistance measuring instrument 400, which has a first port and a second port for connecting to the wire clamp 300. The first port is connected to the conductive wire reel 100.

[0029] The resistance meter 400 can be communicatively connected to an alarm. By setting the alarm, it will directly alert personnel when the resistance meter 400 detects an abnormality. In this embodiment, the alarm can be set as an audible and visual alarm, which will immediately issue a voice alert in the event of a malfunction, ensuring the inherent safety of the equipment.

[0030] The resistance meter 400 is electrically connected to the aircraft refueling truck. When the aircraft refueling truck starts, the resistance meter 400 starts synchronously, which facilitates power supply to the resistance meter 400 without the need for additional power supply equipment.

[0031] It also includes a first measuring line 410 and a second measuring line 420 for connection to the clamp 300. The two ends of the first measuring line 410 are connected to the first port and the electrostatic discharge coil 100, respectively, and the second measuring line 420 is connected to the second port. By setting the first measuring line 410 and the second measuring line 420, it is convenient to electrically connect the resistance meter 400 and the electrostatic discharge coil 100 as a whole.

[0032] The working principle of the electrostatic conductive wire device in this embodiment is as follows:

[0033] During use, the conductive wire reel 100 is installed on the aircraft refueling truck. Pulling the clamp 300 releases the conductive wire 200 wound on the reel 100, and clamping the clamp 300 onto the aircraft. This balances the potential between the refueling truck and the aircraft during refueling. After the work is completed, clamp the clamp 300 at the second port. The resistance meter 400 measures the overall resistance of the conductive wire reel 100, conductive wire 200, clamp 300, and aircraft refueling truck. When the resistance is normal, there are no abnormalities in the conductive wire reel 100, conductive wire 200, clamp 300, and aircraft refueling truck. When the resistance is abnormal, there is a malfunction in one of these components. After the vehicle is powered on, the resistance meter also starts. When the conductive clamp is reset, the circuit is connected, and the overall resistance of the conductive wire and the conductive clamp can be monitored. If an open circuit occurs in the measurement range or the resistance value is not up to standard, the resistance meter will display an abnormality. By setting up the resistance meter 400, one end of the resistance meter 400 can be directly connected to the conductive wire reel 100, and the other end of the resistance meter 400 can be connected to the conductive wire reel 100 through the clamp 300. This allows for quick detection of the overall continuity of the conductive wire device, reducing the long-term maintenance burden on on-site personnel.

[0034] This static electricity conductive wire device can not only balance the potential between the aircraft refueling truck and the aircraft during refueling, but also directly ground the device. It can be clamped onto vehicles used for receiving and dispensing oil at oil depots or other devices that need to avoid generating static electricity using a 300 clamp. This facilitates grounding the device to eliminate static electricity and enables efficient monitoring of the continuity of the static electricity conductive wire. In the event of a fault, an immediate voice alert will be issued to ensure the inherent safety of the equipment.

[0035] Example 2

[0036] This embodiment is the second embodiment of the electrostatic discharge wire device. This embodiment is similar to the first embodiment, except that, as Figure 1 As shown, the conductive wire 200 and the first measuring wire 410 are connected to both ends of the conductive wire reel 100, respectively. This facilitates the resistance measuring instrument 400 in measuring the overall resistance of the conductive wire device.

[0037] like Figure 2As shown, the conductive wire reel 100 includes a rotating shaft 110 and a roller 120. The roller 120 is sleeved outside the rotating shaft 110 and is rotatably connected to the rotating shaft 110. The roller 120 is also electrically connected to the rotating shaft 110. One end of the roller 120 is connected to the conductive wire 200, and the other end of the roller 120 is electrically connected to a first port. The conductive wire reel 100 is fixedly connected to the aircraft refueling vehicle via the rotating shaft 110. The roller 120 rotates on the rotating shaft 110 to wind up and unwind the conductive wire 200. By connecting the conductive wire 200 to the roller 120, it is easy to ensure that the conductive wire 200 and the roller 120 are always stably conductive, and it is also easy to store the conductive wire 200 on the roller 120. In this embodiment, the rotating shaft 110 passes through the roller 120 and has threads, which are used to fix it to the aircraft refueling vehicle. Alternatively, a mounting bracket may be provided, with the rotating shaft 110 fixedly connected to the mounting bracket, and the mounting bracket fixedly connected to the aircraft refueling vehicle.

[0038] like Figure 2 As shown, the conductive wire reel 100 also includes a conductive slip ring 130, which is mounted on the drum 120 or the shaft 110. The two ends of the conductive slip ring 130 are electrically connected to the drum 120 and the shaft 110, respectively. By setting the conductive slip ring 130, a stable electrical connection between the shaft 110 and the drum 120 is maintained during wire winding and unwinding, ensuring that the aircraft refueling truck and the aircraft are always stably connected. This avoids problems such as high resistance or dust accumulation caused by friction and the accumulation of impurities, reducing the long-term maintenance burden on on-site personnel for the conductive wire device.

[0039] like Figure 3 As shown, the conductive slip ring 130 includes a stator portion 131, a mounting portion 132, and a rotor portion 133 connected in sequence. The mounting portion 132 is fixedly connected to the roller 120, the stator portion 131 is electrically connected to the roller 120, and the rotor portion 133 is electrically connected to the rotating shaft 110. The mounting portion 132 fixes the position of the conductive slip ring 130, and the stator portion 131 and the rotor portion 133 are electrically connected to the rotating shaft 110 and the roller 120 respectively, maintaining a stable electrical connection between the rotating shaft 110 and the roller 120 while rotating.

[0040] like Figure 4 As shown, the rotating shaft 110 has a countersunk hole 111, and the rotor part 133 is located inside the countersunk hole 111. The rotor part 133 is rotatably connected to the rotating shaft 110. The rotor part 133 has a rotor outlet end, which is electrically connected to the rotating shaft 110. That is, in this embodiment, the connection method between the rotor end of the conductive slip ring 130 and the rotating shaft 110 is as follows: the wiring lug of the rotor end wire is fixed in the countersunk hole 111 by an M3 bolt. When the conductive slip ring 130 rotates, the conductive slip ring 130 is always located inside the countersunk hole 111 to improve space utilization and electrostatic transmission efficiency, thereby maintaining a stable electrical connection between the rotating shaft 110 and the drum 120 during wire winding and unwinding.

[0041] The electrostatic discharge coil 100 also includes an inner shell 140 and an outer shell 150. The inner shell 140 is detachably connected to the roller 120 and is fitted over the stator portion 131. The mounting portion 132 engages with the inner shell 140. The outer shell 150 is fitted over the inner shell 140 and is electrically connected to the roller 120. The stator portion 131 has a stator output terminal, which is electrically connected to the outer shell 150. The inner shell 140 and outer shell 150 secure the conductive slip ring 130 and facilitate its disassembly and maintenance.

[0042] The mounting part 132 has mounting holes, and the inner shell 140 has protrusions that are inserted into the mounting holes. Inserting the protrusions into the mounting holes facilitates the installation of the conductive slip ring 130. In this embodiment, the inner cylinder has three protrusions evenly distributed around its circumference, and the mounting part 132 has three mounting holes.

[0043] The inner shell 140 and the outer shell 150 are threaded together, specifically, the inner shell 140 has external threads and the outer shell 150 has internal threads. This ensures a stable connection between the inner shell 140 and the outer shell 150.

[0044] The second reel 170 and the shaft 110 are prone to accumulating large amounts of copper shavings or dust due to long-term friction, leading to poor contact. Unlike the traditional method of using copper rods in direct contact with the conductive wire reel, a conductive slip ring 130 is installed to maintain a stable electrical connection between the shaft 110 and the second reel 170 during wire winding and unwinding. This ensures that the aircraft refueling truck and the aircraft are always in a stable conductive state, avoiding problems such as high resistance or dust accumulation caused by friction and impurities. It effectively prevents the accumulation of copper shavings or dust between the reel and the roller end face, reducing the resistance increase caused by poor contact. Therefore, it can significantly reduce the frequency and labor costs of regular inspection and maintenance of the conductive wire resistance, reducing the long-term maintenance pressure on on-site personnel. At the same time, the high conductivity design allows the conductive wire device to maintain stable performance in harsh environments or under long-term operation, reducing equipment failures and downtime caused by unqualified resistance, and enhancing the overall reliability of the equipment.

[0045] Example 3

[0046] This embodiment is the third embodiment of the electrostatic discharge wire device. This embodiment is similar to embodiment two, except that, as Figure 2As shown, the electrostatic conductive wire reel 100 also includes a first wire reel 160 and a second wire reel 170. The outer diameters of both the first wire reel 160 and the second wire reel 170 are larger than the outer diameter of the roller 120. The first wire reel 160 and the second wire reel 170 are fixedly connected to both ends of the roller 120, respectively. One end of the rotating shaft 110 passes through the first wire reel 160. In this embodiment, the rotating shaft 110 uses a bolt, one end of which is threaded. The threaded end of the bolt passes through the first wire reel 160, and the thread on the bolt facilitates a stable connection between the electrostatic conductive wire reel 100 and the frame of the aircraft refueling truck. The other end of the rotating shaft 110 is electrically connected to the second wire reel 170. The first measuring line 410 is connected to the first wire reel 160, and the electrostatic conductive wire 200 is connected to the second wire reel 170. In this embodiment, the connection between the electrostatic conductive wire 200 and the second wire reel 170 is achieved by using an M8 bolt to fix the connecting lug of the electrostatic conductive wire 200 to a pre-drilled hole on the second wire reel 170. By setting the first reel 160 and the second reel 170, the static-dissipating wire 200 wound on the roller 120 is prevented from falling off from both ends of the roller 120.

[0047] The second reel 170 is equipped with a handle 180. The handle 180 drives the second reel 170 to rotate, which facilitates the winding of the electrostatic conductive wire 200 onto the roller 120.
