Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, in particular to a GIS ultra-high frequency detector increasing device. Background Art

[0002] During the daily operation and maintenance of the substation, it is necessary to perform ultra-high frequency live detection on the GIS equipment (GAS INSULATED SWITCHGEAR is the English abbreviation for gas-insulated fully enclosed switchgear) in the substation on a periodic basis. The GIS ultra-high frequency live detection equipment is a rectangular module. Under normal circumstances, the GIS equipment can only be tested by hand (hand touching the module). The current problems with the device used to hang the safety belt on the top of the transformer are mainly the following:

[0003] 1. Currently, the UHF detection equipment for GIS equipment can only be carried out by hand-held mode, placing the UHF detection equipment at the detection port for detection, without other auxiliary equipment.

[0004] 2. Holding the UHF detector can easily cause hand fatigue.

[0005] 3. After holding the UHF detector for a long time, due to hand fatigue, the GIS UHF detection equipment may fall, damaging the detection instrument and possibly causing damage to the GIS equipment, posing a great safety risk.

[0006] 4. The current typical GIS design has a compact structure and a tight layout. Since GIS ultra-high frequency detection requires detection of multiple locations on the GIS equipment, the compact structure results in a small detection space, and some detection locations are difficult to reach for detection.

[0007] 5. The height of GIS equipment is generally 4 meters or above. When inspectors conduct ultra-high frequency live inspection on GIS equipment, they need to carry auxiliary equipment such as ladders to inspect high-altitude inspection ports, which makes inspectors easily fatigued and has low inspection efficiency. Summary of the invention

[0008] In order to solve the problem of low detection efficiency caused by easy fatigue and shaking during hand-held detection due to large height difference when using a hand-held detector to detect GIS equipment at high places, the present invention provides a GIS ultra-high frequency detector holding device.

[0009] The present invention is achieved through the following technical solutions:

[0010] A GIS ultra-high frequency detector holding device, comprising an inner connecting rod made of insulating material, the top end of which is connected to a clamping device capable of assembling the detector through an angle adjustment adapter;

[0011] A base is provided at the lower part of the inner connecting rod, and the base includes a seat tube mounted on the lower part of the inner connecting rod, and the top end of the seat tube is used to adjust the length of the inner connecting rod extending outward through a locking assembly; the bottom end of the seat tube is connected to a pedal assembly, and the pedal assembly includes a plurality of upper pedals surrounding the seat tube and hinged to the seat tube, and the plate surface of the upper pedals is perpendicular to the radial line of the seat tube in the initial state.

[0012] The angle adjustment adapter and the clamping device are placed at the top of the inner connecting rod to adapt to the problem of narrow space around the equipment to be tested; the upper part of the seat tube locks and fixes the extended inner connecting rod through a locking assembly, and the upper pedal hinged at the lower part is placed on the ground for easy operation and serves as a part that can be stepped on, thereby increasing structural stability, sharing the operating pressure of hand-held, and improving detection efficiency.

[0013] A further improvement of the present invention is that the pedal assembly further comprises a lower pedal and a counterweight; the lower pedal is hinged to the lower end of the upper pedal by a spring, the lower pedal and the upper pedal are folded around the spring hinge, and the upper pedal and the lower pedal protrude away from the seat tube; the counterweight is connected to the lower end of the lower pedal. The lower end of the upper pedal is hinged to the lower pedal, and under the action of the counterweight, it can be restored to its original state whether placed vertically or sideways when idle, so as to reduce the occupation of external space.

[0014] A further improvement of the present invention is that the length of the lower pedal is less than that of the upper pedal, which helps to increase the angle at which the lower pedal can be turned and reduce the distance between the lower end of the upper pedal and the ground when the upper pedal is in use.

[0015] A further improvement of the present invention is that guide rods connected to the counterweight are provided on both sides of the lower pedal, the axis of the guide rods is perpendicular to the top surface of the counterweight, and the bottom end surface of the seat tube is provided with guide holes that match the guide rods. The guide rods match the guide holes to help limit the trajectory of the counterweight relative to the seat tube, and at the same time prevent the counterweight from affecting the flipping direction of the pedal due to its own weight.

[0016] A further improvement of the present invention is that the height difference between the upper pedal and the lower pedal before and after folding is equal to the stroke of the guide rod extending into the guide hole. That is, when the upper pedal and the lower pedal are folded to the minimum angle under the action of the spring hinge, the guide rod just extends into the inner end of the guide hole, thereby forming a cooperation between the guide rod and the guide hole to reduce the force between the two pedals.

[0017] A further improvement of the present invention is that the inner sides of the upper pedal and the lower pedal are respectively provided with stop blocks that can cooperate with each other. When the two stop blocks abut against each other when the two pedals are folded to a minimum angle, it helps to reduce the force load of the spring hinge.

[0018] A further improvement of the present invention is that the above-mentioned counterweight block is annular in structure as a whole, corresponding to the seat tube structure, and forms a certain weight reduction effect.

[0019] A further improvement of the present invention is that the locking assembly includes a clamping sheet and a locking screw ring, a plurality of clamping sheets are provided, and the plurality of clamping sheets are arranged around the top end of the seat tube, an external thread is provided on the outer wall of the plurality of clamping sheets, and the internal thread of the locking nut cooperates with the external thread to realize the clamping of the inner connecting rod by the clamping sheet. The locking screw ring cooperates with the clamping sheet to realize the clamping and fixing of the inner connecting rod.

[0020] A further improvement of the present invention is that the lower end of the outer wall of the inner connecting rod is provided with a plurality of annular grooves evenly distributed along the axial direction, and the inner wall of the pressing plate is provided with a fixing protrusion that can cooperate with the annular groove. The fixing protrusion and the annular groove cooperate with each other to prevent the inner connecting rod from retracting during operation.

[0021] It can be seen from the above technical scheme that the beneficial effects of the present invention are: the angle adjustment adapter and the clamping device are placed at the top of the inner connecting rod to adapt to the problem of narrow space around the equipment to be tested; the upper part of the seat tube locks and fixes the extended inner connecting rod through a locking assembly, and the upper pedal hinged at the lower part is placed on the ground for easy operation, and serves as a component that can be stepped on, thereby increasing structural stability, sharing the operating pressure of hand-held, and improving detection efficiency.

DETAILED DESCRIPTION

[0032] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0033] As attached Figure 1-8 As shown, a GIS ultra-high frequency detector supporting device includes an inner connecting rod 30 made of insulating material. The inner connecting rod 30 is provided with multiple sections, and the multiple sections of the inner connecting rod 30 are telescopically sleeved; the top end of the inner connecting rod 30 is connected to a clamping device 50 that can be assembled with the detector through an angle adjustment adapter 40; the angle adjustment adapter 40 and the clamping device 50 are placed at the top end of the inner connecting rod 30 to adapt to the problem of narrow space around the equipment to be detected.

[0034] The lower part of the inner connecting rod 30 is provided with a base 10, and the base 10 includes a seat tube 11 sleeved on the lower part of the inner connecting rod 30. The top of the seat tube 11 is used to adjust the length of the inner connecting rod 30 extending outward; the upper part of the seat tube 11 is locked and fixed by the locking assembly. The locking assembly includes a clamping sheet 12 and a locking screw 13. There are multiple clamping sheets 12, and multiple clamping sheets 12 are arranged around the top of the seat tube 11. The outer walls of the multiple clamping sheets 12 are provided with external threads, and the internal threads of the locking nut cooperate with the external threads to realize the clamping of the clamping sheet 12 on the inner connecting rod 30. The locking screw 13 cooperates with the clamping sheet 12 to realize the clamping and fixing of the inner connecting rod 30. The lower end of the outer wall of the inner connecting rod 30 is provided with multiple annular grooves 31 evenly distributed along the axial direction, and the inner wall of the clamping sheet 12 is provided with a fixing protrusion 14 that can cooperate with the annular groove 31. The fixing protrusion 14 cooperates with the annular groove 31 to prevent the inner connecting rod 30 from retracting during operation.

[0035] The length of the lower pedal 22 is less than that of the upper pedal 21. This helps to increase the angle at which the lower pedal 22 can flip and reduce the distance between the lower end of the upper pedal 21 and the ground when the upper pedal 21 is in use.

[0036] The bottom end of the seat tube 11 is connected with a pedal assembly 20, which includes a plurality of upper pedals 21 surrounding the seat tube 11 and hinged to the seat tube 11. In the initial state, the board surface of the upper pedal 21 is perpendicular to the radial line of the seat tube 11. The upper pedal 21 hinged at the bottom is conveniently placed on the ground during operation, and as a component that can be stepped on, it increases the structural stability, shares the operating pressure of hand-held, and improves the detection efficiency.

[0037] The pedal assembly 20 further includes a lower pedal 22 and a counterweight 24; the lower pedal 22 is hinged to the lower end of the upper pedal 21 through a spring, the lower pedal 22 and the upper pedal 21 are folded around the spring hinge, and the upper pedal 21 and the lower pedal 22 protrude to the side away from the seat tube 11; the counterweight 24 is connected to the lower end of the lower pedal 22. The counterweight 24 is an annular structure as a whole. It corresponds to the structure of the seat tube 11 and forms a certain weight reduction effect. The lower end of the upper pedal 21 is hinged with the lower pedal 22, and under the action of the counterweight 24, it can be restored to its original state when idle, whether placed vertically or sideways, so as to reduce the occupation of external space.

[0038] The inner side surfaces of the upper pedal 21 and the lower pedal 22 are respectively provided with stoppers 25 that can cooperate with each other. When the two stoppers 25 are folded to the minimum angle, they abut against each other, which helps to reduce the force load of the spring hinge.

[0039] Both sides of the lower pedal 22 are provided with guide rods 23 connected to the counterweight 24, the axis of the guide rods 23 is perpendicular to the top surface of the counterweight 24, and the bottom end surface of the seat tube 11 is provided with guide holes that match the guide rods 23. The guide rods 23 match the guide holes, which helps to limit the trajectory of the counterweight 24 moving relative to the seat tube 11, and at the same time prevent the counterweight 24 from affecting the flipping direction of the pedal due to its own weight.

[0040] The height difference between the upper pedal 21 and the lower pedal 22 before and after folding is equal to the stroke of the guide rod 23 extending into the guide hole. That is, when the upper pedal 21 and the lower pedal 22 are folded to the minimum angle under the action of the spring hinge, the guide rod 23 just extends into the inner end of the guide hole, thereby forming a cooperation between the guide rod 23 and the guide hole to reduce the force between the two pedals.

[0041] In summary, when the device is used: first, the detector is placed in the clamping device 50 and fixed, and the angle adjustment adapter 40 is operated in advance to adjust the adaptable angle according to the observation of the surrounding environment of the device to be tested. Then, the inner connecting rod 30 close to one end of the clamping device 50 is pulled outward in advance according to the approximate distance, and the locking assembly is operated to fix the overall length, and then the seat tube is pressed down, so that the upper pedal 21 and the lower pedal 22 begin to be compressed and folded to the limit under the action of the hinge; because the length of the lower pedal 22 is smaller than that of the upper pedal 21, the lower pedal 22 can be flipped at a larger angle when compressed and folded, and the flipped lower pedal 22 is closer to the horizontal, so that the lower end of the upper pedal 21 is closer to the ground; the operator can step on the upper pedal 21 to reduce the force of holding the rod body.

[0042] The present invention describes a GIS ultra-high frequency detector holding device, in which an angle adjustment adapter and a clamping device are placed at the top of an inner connecting rod to accommodate the problem of narrow space around the equipment to be detected; the upper part of the seat tube locks and fixes the extended inner connecting rod through a locking assembly, and the upper pedal hinged at the lower part is placed on the ground for easy operation, and serves as a component that can be stepped on, thereby increasing structural stability, sharing the operating pressure of hand-held, and improving detection efficiency.
