Description

Technical Field

[0001] The invention relates to the technical field of discharge devices, in particular to an electrical test remote control discharge device. Background Art

[0002] When conducting electrical tests, workers need to discharge the relevant test equipment. For example, after the voltage test, workers need to discharge the test equipment for a long time and multiple times. Test equipment usually has the ability to store energy, and the safety of workers can only be guaranteed after it is discharged by the discharge device.

[0003] The discharge device currently used is a discharge rod, the length of which is telescopic and adjustable.

[0004] Before the discharge operation, preparation work is required. The test personnel need to wear cotton long-sleeved work clothes, wear a safety helmet, and stand on an insulating mat. This preparation work takes a long time and leads to low work efficiency.

[0005] When performing the discharge operation, the worker extends the discharge rod to an appropriate length and holds the discharge rod in contact with the charged part of the test equipment, or hangs the discharge rod on the charged part of the test equipment, so that the residual charge of the test equipment is connected to the grounding grid through the discharge head of the discharge rod and the grounding wire in sequence. In this discharge operation, because the worker holds the discharge rod in hand to operate, there is a risk of accidents caused by negligence or failure to comply with safety operating procedures, which reduces the safety of the worker.

[0020] 2. From the perspective of time efficiency, after the discharge device of the present invention is put into operation, since there is no need for workers to enter the working area and to wear protective equipment for preparation, the working time can be effectively shortened, which is conducive to improving work efficiency.

[0021] 3. Because the discharge operation is performed by remote control and no staff operation is required, manpower can be saved.

[0022] 4. The discharge device of the present invention is easy to use, reliable and easy to carry.

[0023] 5. The discharge device of the present invention can save costs by reducing the safety risks of workers and alleviating the complexity of operation, thereby achieving greater economic benefits.

[0024] 6.

[0028] 10. By arranging two discharge fork rods on the discharge head, the auxiliary discharge tools include a charged ring, a charged extension rod and a charged fork rod. When conducting a discharge test, the two discharge fork rods are inserted between the two charged fork rods. At this time, the tension of the two discharge fork rods and the friction between the discharge fork rods and the charged fork rods can be utilized to allow the discharge fork rods and the charged fork rods to maintain stable contact, thereby improving the contact reliability between the discharge device of this embodiment and the charged body of the test equipment, reducing the risk of loose connection of the telescopic discharge rod, and further preventing the risk of residual charge in the test equipment causing harm to the human body due to insufficient discharge.

[0031] 13. The first limit sensor and the second limit sensor are used to limit the moving range of the push plate, which can ensure the safe and stable operation of the discharge device of the present invention.

[0032] 14. By installing the battery inside the chassis, no external power supply is required, making the entire discharge device more convenient to use. By installing a door on the side wall of the chassis, it is convenient for workers to take out the battery for charging, and it is also convenient to inspect and maintain the swing mechanism in the chassis, which improves the convenience of use.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0053] Embodiment 1:

[0054] An electrical test remote control discharge device comprises a chassis 1, a telescopic discharge rod, a swing mechanism and a remote control module.

[0055] See also Figure 1 The side wall of the chassis 1 is provided with a avoiding hole 11.

[0056] The telescopic discharge rod comprises an insulating telescopic structure, a discharge head 3 and a grounding wire 6 .

[0057] See also Figure 1 , Figure 2 and Figure 3 The lower part of the insulating telescopic structure is arranged in the avoidance hole 11. Figure 3 The lower part of the insulating telescopic structure is rotatably connected to the inner wall of the chassis 1 through the rotating shaft 211. Figure 1 The avoidance hole 11 has enough space to allow the insulating telescopic structure to swing around the rotating shaft 211. The insulating telescopic structure is electrically connected to the remote control module, and the remote control module is used to remotely adjust the length of the insulating telescopic structure.

[0058] See also Figure 3 The discharge head 3 is fixedly mounted on the top of the insulating telescopic structure. The discharge head 3 is connected to the grounding wire 6. The discharge head 3 is used to contact the charged body of the test equipment to release the charge of the test equipment.

[0059] See also Figure 2 and Figure 3 The swing mechanism is arranged inside the chassis 1, and is used to adjust the tilt angle of the telescopic discharge rod. The swing mechanism includes a swing driving device, a swing screw 82, a push plate 83 and a connecting arm 84.

[0060] See also Figure 2 The swing driving device is used to drive the swing screw 82 to rotate. The swing driving device can adopt a first servo motor 81. The first servo motor 81 is fixedly installed inside the chassis 1. The output shaft of the first servo motor 81 is fixedly connected to the end of the swing screw 82. The first servo motor 81 is electrically connected to the remote control module, and the remote control module is used to remotely control the start and stop of the first servo motor 81.

[0061] See also Figure 2 and Figure 3 The push plate 83 is threadedly connected to the swing screw 82, and the push plate 83 is slidably connected to the inner bottom wall of the chassis 1. In order to further improve the stability of the push plate 83, a guide rail 85 is fixedly installed on the inner bottom wall of the chassis 1, and the push plate 83 is slidably connected to the guide rail 85. The upper part of the push plate 83 is rotatably connected to the lower part of the connecting arm 84, and the upper part of the connecting arm 84 is rotatably connected to the side wall of the insulating telescopic structure.

[0062] The working principle of the swing mechanism is as follows: when the first servo motor 81 drives the swing screw 82 to rotate forward, the push plate 83 threadedly connected to the swing screw 82 moves in a direction away from the first servo motor 81, and the push plate 83 pushes the connecting arm 84 to move together, and the connecting arm 84 pushes the insulating telescopic structure to swing in a direction away from the chassis 1. When the first servo motor 81 drives the swing screw 82 to rotate reversely, the push plate 83 threadedly connected to the swing screw 82 moves in a direction close to the first servo motor 81, and the push plate 83 drives the connecting arm 84 to move together, and the connecting arm 84 drives the insulating telescopic structure to swing in a direction close to the chassis 1. When the insulating telescopic structure swings, the inclination angle of the insulating telescopic structure is changed.

[0063] See also Figure 2 The swing mechanism also includes a first limit sensor 86 and a second limit sensor 87. The first limit sensor 86 and the second limit sensor 87 are both fixedly mounted on the inner wall of the chassis 1. The first limit sensor 86 is located at one end of the swing screw 82 close to the first servo motor 81, and the second limit sensor 87 is located at one end of the swing screw 82 away from the first servo motor 81. The first limit sensor 86 and the second limit sensor 87 are both electrically connected to the remote control module. In this embodiment 1, the first limit sensor 86 and the second limit sensor 87 can both adopt a micro switch or a photoelectric switch. The first limit sensor 86 and the second limit sensor 87 are used to limit the moving range of the push plate 83, which can ensure the safe and stable operation of the discharge device of this embodiment 1.

[0064] See also Figure 2 The case 1 is provided with a battery 9, which can be a lithium battery, and is used to supply power to the insulating telescopic structure, the first servo motor 81, the first limit sensor 86 and the second limit sensor 87. By using a lithium battery as a power source, no external power source is required, making the entire discharge device more convenient to use. In order to facilitate the removal of the battery 9 from the case 1 and charge the battery 9, see Figure 1 The side wall of the chassis 1 is provided with a door 12. By opening the door 12, the internal space of the chassis 1 can be opened, so that workers can take out the battery 9 for charging, and it is also convenient to inspect and maintain the swing mechanism in the chassis 1.

[0065] The working principle of this embodiment 1 is as follows:

[0066] (1) The staff places the chassis 1 near the target test equipment and connects the chassis 1 to the grounding grid to facilitate the introduction of the residual charge of the discharge device of Example 1 into the grounding grid, ensuring the safety of the discharge device and personnel. In addition, the grounding wire 6 needs to be manually connected to the grounding grid so that the residual charge of the test equipment can be introduced into the grounding grid during the subsequent discharge operation.

[0067] (2) The staff retreats to a safe position. The staff controls the swing mechanism to adjust the inclination angle of the insulating telescopic structure through the remote control module, and controls the length of the insulating telescopic structure through the remote control module. When the discharge head 3 located at the top of the insulating telescopic structure contacts the charged body of the test equipment, the staff shuts down the swing mechanism and the insulating telescopic structure through the remote control module to keep the current state of the discharge head 3 contacting the charged body. At this time, the residual charge of the test equipment can be released to the grounding grid through the discharge head 3 and the grounding wire 6 in turn.

[0068] (3) After the discharge operation is completed, the staff controls the insulating telescopic structure and the swing mechanism to reset to the initial state through the remote control module, so that the discharge head 3 located on the top of the insulating telescopic structure leaves the charged body of the test equipment.

[0069] According to the above working principle, it can be seen that Example 1 has the following effects:

[0070] First, from the perspective of safety and benefits, after the discharge device of this embodiment 1 is put into operation, the length and tilt angle of the telescopic discharge rod can be adjusted remotely without manual operation by the staff, which reduces the risk of injury to the staff and improves work safety.

[0071] Second, from the perspective of time efficiency, after the discharge device of the present embodiment 1 is put into operation, since there is no need for workers to enter the working area and to wear protective equipment for preparation, the working time can be effectively shortened, which is conducive to improving work efficiency.

[0072] During the 20-day test phase, the total working time was 6 minutes, and 40 test discharges were completed. Compared with the past, it took about 40 minutes to manually discharge 40 times with a handheld discharge rod in 20 days. This is a 34-minute reduction. It is expected to save 50 minutes in 2024.

[0073] Third, since the discharge operation is performed remotely, no staff operation is required, which can save manpower.

[0074] Fourthly, the discharge device of the present embodiment 1 is easy and reliable to use and easy to carry.

[0075] Fifth, the discharge device of the present embodiment 1 can save costs by reducing the safety risks of the workers and alleviating the complexity of the operation, thereby achieving greater economic benefits.

[0076] For further information, see Figure 4, an insulating hoop 32 is fixedly mounted on the discharge head 3, and an anti-electric shock warning device 7 is fixedly mounted on the outer wall of the insulating hoop 32. The provision of the insulating hoop 32 can prevent the anti-electric shock warning device 7 from directly contacting the discharge head 3, thereby preventing the anti-electric shock warning device 7 from being damaged by a short circuit. The anti-electric shock warning device 7 can adopt a near-electric alarm, which is an existing product. When the test equipment or the discharge device itself is still charged, the near-electric alarm sounds an alarm. By installing the anti-electric shock warning device 7, it is possible not only to check whether there is any residual charge in the test equipment, but also to check whether there is any residual charge in the discharge device of this embodiment 1, so as to ensure the personal safety of the staff, which is conducive to improving safety.

[0077] Embodiment 2:

[0078] This embodiment 2 provides a specific structural form of the insulating telescopic structure in embodiment 1:

[0079] See also Figure 5 The insulating telescopic structure includes a first insulating sleeve 21, a second insulating sleeve 22, a telescopic screw 23 and a telescopic driving device.

[0080] See also Figure 5 The first insulating sleeve 21 is a cylindrical structure with an open upper end. Figure 3 The lower side portion of the first insulating sleeve 21 is rotatably connected to the inner wall of the chassis 1 through the rotating shaft 211.

[0081] See also Figure 5 The telescopic screw 23 is arranged inside the first insulating sleeve 21 .

[0082] See also Figure 5 The telescopic drive device is used to drive the telescopic screw 23 to rotate. The telescopic drive device uses a second servo motor 24, which is fixedly installed at the bottom of the first insulating sleeve 21. The output shaft of the second servo motor 24 is fixedly connected to the telescopic screw 23 after passing through the bottom of the first insulating sleeve 21. The second servo motor 24 is electrically connected to the remote control module, and the remote control module is used to remotely control the start and stop of the second servo motor 24. The battery 9 supplies power to the second servo motor 24.

[0083] See also Figure 5 The second insulating sleeve 22 is slidably matched with the inner cavity of the first insulating sleeve 21 along the axial direction of the first insulating sleeve 21. A threaded cavity 221 is provided inside the second insulating sleeve 22. The threaded cavity 221 is threadedly connected with the telescopic screw 23. Figure 4 The discharge head 3 is fixedly mounted on the top of the second insulating sleeve 22 .

[0084] The working principle of the insulating telescopic structure of this embodiment 2 is as follows:

[0085] When the staff remotely controls the output end of the second servo motor 24 to rotate forward through the remote control module, the output end of the second servo motor 24 drives the telescopic screw 23 to rotate forward, and the second insulating sleeve 22 threadedly connected to the telescopic screw 23 moves upward, thereby increasing the length of the entire insulating telescopic structure.

[0086] When the staff remotely controls the output end of the second servo motor 24 to reverse through the remote control module, the output end of the second servo motor 24 drives the telescopic screw 23 to reverse, and the second insulating sleeve 22 threadedly connected to the telescopic screw 23 moves downward, so that the length of the entire insulating telescopic structure is reduced.

[0087] When the staff turns off the second servo motor 24 through the remote control module, the telescopic screw 23 stops rotating and the second insulating sleeve 22 stops moving, so that the entire insulating telescopic structure remains at the current length.

[0088] It can be seen from the above working principle that the insulating telescopic structure provided in this embodiment 2 can be adjusted in length by electric drive.

[0089] Embodiment 3:

[0090] In the second embodiment, the grounding wire 6 may be located outside the insulating telescopic structure. In order to avoid cluttered lines and to protect the grounding wire 6, the third embodiment improves the chassis 1 and the insulating telescopic structure in the second embodiment as follows:

[0091] See also Figure 1 and Figure 3 The side wall of the chassis 1 is provided with a wire outlet hole 13.

[0092] See also Figure 5 The second insulating sleeve 22 has a wiring cavity 222 disposed therein, the top of the wiring cavity 222 passes through the top surface of the second insulating sleeve 22, and the bottom of the wiring cavity 222 communicates with the interior of the first insulating sleeve 21. The lower side of the first insulating sleeve 21 has a wiring hole 212 disposed therein.

[0093] See also Figure 3 and Figure 5 One end of the grounding wire 6 is connected to the discharge head 3 after passing through the wire outlet hole 13, the inner cavity of the chassis 1, the wiring hole 212, the inside of the first insulating sleeve 21, and the wiring cavity 222 in sequence. The other end of the grounding wire 6 is arranged outside the chassis 1, and the end of the grounding wire 6 located outside the chassis 1 is connected to the grounding grid.

[0094] When the discharge test is not performed, the grounding wire 6 can be accommodated in the chassis 1, and there is enough space inside the chassis 1 to accommodate the grounding wire 6. When the discharge test is performed, one end of the grounding wire 6 for accessing the grounding grid can be extended from the outlet hole 13.

[0095] From the above introduction, it can be known that by setting a wiring cavity 222 inside the second insulating sleeve 22 and setting a wiring hole 212 on the side of the first insulating sleeve 21, a section of the grounding wire 6 connected to the discharge head 3 can be hidden inside the insulating telescopic structure, which can avoid cluttered lines, make the test site tidier, and protect the grounding wire 6.

[0096] By setting a wire outlet hole 13 on the side wall of the chassis 1, when the discharge test is not performed, the grounding wire 6 can be accommodated in the chassis 1, which is more convenient to transfer and carry. When the discharge test is performed, the end of the grounding wire 6 used for grounding can be extended from the wire outlet hole 13 on the side of the chassis 1, which is convenient and flexible to use.

[0097] Embodiment 4:

[0098] This embodiment 4 is further improved on the basis of embodiment 1 or embodiment 2 or embodiment 3: Figure 4 Two discharge fork rods 31 are provided at the upper end of the discharge head 3 , and the discharge fork rods 31 and the discharge head 3 are an integral structure.

[0099] In addition, in the prior art, the charged body of the test equipment includes a charged screw 41 and a charged ball seat 42. The charged screw 41 is fixedly installed on the test equipment, and the charged screw 41 is threadedly connected with the charged ball seat 42. Figure 6 and Figure 7 When the test equipment is a reactor 4 , the charged screw 41 is fixedly installed on the top of the reactor 4 , and the charged screw 41 is threadedly connected to the charged ball seat 42 .

[0100] This embodiment 4 is further improved, and the test equipment is also provided with an auxiliary discharge tool, see Figure 6 The auxiliary discharge tool includes a charged ring 51, a charged extension rod 52 and a charged fork rod 53. The charged ring 51 is provided with a charged extension rod 52 on its side, and the charged extension rod 52 is provided with two charged fork rods 53 at one end away from the charged ring 51. The charged ring 51, the charged extension rod 52 and the charged fork rod 53 are an integrated structure.

[0101] Taking the installation of the auxiliary discharge tool on the reactor 4 as an example, the charged ring 51 is first put on the charged screw 41, and then the charged ball seat 42 is screwed onto the charged screw 41, so that the charged ring 51 is pressed on the top surface of the reactor 4 by the charged ball seat 42, and the charged extension rod 52 extends the charged fork rod 53 to the outside of the reactor 4.

[0102] See also Figure 8 and Fig. 9When conducting a discharge test, the staff controls the swing mechanism through the remote control module to adjust the inclination angle of the insulating telescopic structure, and controls the length of the insulating telescopic structure through the remote control module, so that the two discharge fork rods 31 on the discharge head 3 are inserted between the two charged fork rods 53 in the auxiliary discharge tool, and the tension between the two discharge fork rods 31 is used to make the side walls of the discharge fork rod 31 abut against the side walls of the charged fork rod 53. The tension between the two discharge fork rods 31 and the friction between the discharge fork rod 31 and the charged fork rod 53 can keep the discharge fork rod 31 and the charged fork rod 53 in stable contact. The residual charge of the test equipment can be released to the grounding grid through the charged screw 41, the charged ball seat 42, the charged ring 51, the charged extension rod 52, the charged fork rod 53, the discharge fork rod 31, the discharge head 3, and the grounding wire 6 in sequence.

[0103] From the above introduction, it can be known that by arranging two discharge fork rods 31 on the discharge head 3, the auxiliary discharge tool includes a charged ring 51, a charged extension rod 52 and a charged fork rod 53. When performing a discharge test, the two discharge fork rods 31 are inserted between the two charged fork rods 53. At this time, the tension of the two discharge fork rods 31 and the friction between the discharge fork rods 31 and the charged fork rods 53 can be utilized to allow the discharge fork rods 31 and the charged fork rods 53 to maintain stable contact, thereby improving the contact reliability between the discharge device of this embodiment and the charged body of the test equipment, reducing the risk of the telescopic discharge rod being loosely hung, and further preventing the risk of residual charge in the test equipment harming the human body due to insufficient discharge.

[0104] The provision of the charged extension rod 52 can extend the charged fork rod 53 to the outside of the test equipment. When the discharge fork rod 31 is plugged into the charged fork rod 53, the plugging operation space can be increased, making the plugging more convenient.

[0105] The auxiliary discharge tool has a simple structure and is easy to install. It only requires the charged ring 51 to be sleeved on the charged screw 41, and then the charged ball seat 42 is screwed onto the charged screw 41 so that the charged ring 51 is pressed by the charged ball seat 42, which is beneficial to improving installation efficiency.

[0106] The voltage level of the reactor 4 is generally 10kv, 35kv, 110kv, and the longer the length of the charged extension rod 52 is, the higher the voltage level of the reactor 4 can be matched.
