Description

Technical Field

[0001] The present invention relates to the technical field of electrical testing equipment, and in particular to an electrical testing device and equipment. Background Art

[0002] High-voltage transmission lines are an important part of the power system. Their working conditions are related to the safety, stability and reliability of power supply. Therefore, the inspection and maintenance of transmission lines are very important. In the maintenance of transmission lines, power testing is a necessary step.

[0003] At present, most of the power testing operations on transmission lines require maintenance personnel to climb the pole to perform the routine operations of power testing and grounding, and to ensure the reliability of power testing and grounding. For example, CN202122660800.4 discloses a "two-person pole-held Y-shaped head high-voltage tester".

[0004] Since substation equipment must ensure a sufficient safety distance from the ground during design and installation, the equipment is relatively high from the ground. However, the sizes of the electrometers currently installed in the station are relatively fixed and uniform. Operations often cannot be completed smoothly due to factors such as the electrometer being too short, the operator being short or the equipment being too high. This not only increases safety risks, but also delays operation time. Summary of the invention

[0005] In view of this, it is necessary to provide an electrical testing device and equipment to solve the technical problem in the prior art that operators need to climb up to operate.

[0006] The invention provides an electric test device, which comprises: a driver and an electric tester, wherein the driver has multiple degrees of freedom and is transmission-connected with the electric tester to drive the electric tester to move toward an area to be tested.

[0007] Furthermore, the driver includes a first rotating mechanism, a second rotating mechanism and a telescopic mechanism which are sequentially connected in transmission. The first rotating mechanism is used to drive the second rotating mechanism and the telescopic mechanism to rotate along the rotation axis of the first rotating mechanism. The second rotating mechanism is used to drive the telescopic mechanism to rotate along the rotation axis of the second rotating mechanism. The rotation axis of the first rotating mechanism is intersected with the rotation axis of the second rotating mechanism. The telescopic mechanism is connected in transmission to the electroscope, and the telescopic mechanism is used to drive the electroscope to perform linear reciprocating motion.

[0008] Furthermore, the rotation axis of the first rotating mechanism is perpendicular to the rotation axis of the second rotating mechanism.

[0009] Furthermore, the first rotating mechanism includes a first motor, the second rotating mechanism includes a second motor, the rotating shaft of the first motor is fixedly connected to the second motor, and the rotating shaft of the second motor is fixedly connected to the telescopic mechanism.

[0010] Furthermore, the telescopic mechanism includes a power unit and at least two transmission units that are sequentially connected in transmission. The previous transmission unit of any two adjacent transmission units along the transmission path can transmit one end of the next transmission unit to move away from or close to the previous transmission unit, and the moving directions of the multiple transmission units are the same, so that the driving force of the power unit can be converted into the same-direction linear reciprocating motion of the multiple transmission units. The second rotating mechanism is connected to the power unit in transmission, and the transmission units located at both ends are respectively connected to the power unit and the electroscope. The power unit drives the electroscope to move toward or away from the second rotating mechanism through the transmission unit.

[0011] Furthermore, the transmission unit includes a head-end transmission unit connected to the power unit and a terminal transmission unit connected to the electroscope, and the head-end transmission unit and the terminal transmission unit have the same structure; each transmission unit includes a fixed rod, a moving rod, a guide member and a traction rope, the guide member is arranged at one end of the fixed rod, the moving rod and the fixed rod are arranged in the same direction and the moving rod can be slidably connected to the fixed rod along the axial direction of the fixed rod, and the traction rope passes around the guide member and is fixedly connected to the moving rod; the end of the fixed rod of the head-end transmission unit away from the guide member is fixedly connected to the power output end of the second rotating mechanism, and the end of the traction rope of the head-end transmission unit away from the moving rod is fixedly connected to the power output end of the power unit for pulling the moving rod to move; the end of the fixed rod of the terminal transmission unit away from the guide member is fixedly connected to the moving rod of the head-end transmission unit; the traction rope of the terminal transmission unit away from the moving rod is fixedly connected to the fixed rod of the head-end transmission unit; the electroscope is connected to the moving rod of the terminal transmission unit.

[0012] Furthermore, the transmission unit also includes an intermediate transmission unit with the same structure as the first-end transmission unit. The first-end transmission unit is connected to the terminal transmission unit in turn through several intermediate transmission units. The end of the fixed rod of the intermediate transmission unit away from the guide member is fixedly connected to the moving rod of the previous transmission unit, and the end of the traction rope of the intermediate transmission unit away from the moving rod is fixedly connected to the fixed rod of the previous transmission unit.

[0013] Furthermore, the transmission unit also includes a first connector, which is fixedly connected to the moving rod, the traction rope and the fixed rod of the subsequent transmission unit. The traction rope can drive the moving rod and the fixed rod of the subsequent transmission unit to move synchronously through the first connector; the first connector is also slidably connected to the fixed rod.

[0014] Furthermore, the transmission unit also includes a second connector, which is fixedly connected to the fixed rod and the traction rope of the rear transmission unit. The guide member is arranged on the second connector, and the second connector is also slidably connected to the motion rod.

[0017] The electric test equipment provided by the present invention moves to the vicinity of the tested equipment by carrying the electric test device through a moving trolley, and then drives the electric tester to the testing position through a driver, so that the operator can complete the electric test work away from the high-voltage testing equipment, reducing the safety risk of the operator.

In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the preferred embodiments of the present invention are described in detail as follows with reference to the accompanying drawings.

[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0026] See also Figure 1The electric test device includes a driver 1 and an electric tester 2. The driving end of the driver 1 has multiple degrees of freedom and is transmission-connected to the electric tester 2, and can drive the electric tester 2 to move with multiple degrees of freedom. In this way, the operator does not need to climb up personally, but can move the electric tester 2 through the driver 1 and send the electric tester 2 to the detection position.

[0027] In this embodiment, the driver 1 includes a first rotating mechanism 11, a second rotating mechanism 12 and a telescopic mechanism 13 which are sequentially connected in a transmission manner, wherein the first rotating mechanism 11 and the second rotating mechanism 12 have different rotation directions, thereby providing two rotational degrees of freedom in different directions for the electroscope 2. The telescopic mechanism 13 has a driving end and is transmission-connected to the electroscope 2, and is used to drive the electroscope 2 to perform linear displacement.

[0028] In order to facilitate the operator to operate the driver 1 and reduce the learning difficulty and entry threshold for the operator, the control logic of the driver 1 is preferably in the most common way, that is, to establish a spatial rectangular coordinate system. Therefore, in a preferred embodiment, the rotation axis of the first rotating mechanism 11 is perpendicular to the rotation axis of the second rotating mechanism 12.

[0029] When in use, the first rotating mechanism 11 is placed vertically, with its rotation axis in the vertical direction, and outputs torque on the horizontal plane. The second rotating mechanism 12 is arranged horizontally, with its rotation axis in the horizontal direction, and outputs torque on the vertical plane.

[0030] like Figure 2 As shown, the first rotating mechanism 11 includes a first motor 111 and a first connecting frame 112, and the second rotating mechanism 12 includes a second motor 121 and a second connecting frame 122. The body of the second motor 121 is fixedly connected to the rotating shaft of the first motor 111 through the first connecting frame 112, and the first motor 111 can drive the first connecting frame 112 and the second motor 121 to rotate around the rotating axis of the first motor 111. The telescopic mechanism 13 is fixedly connected to the rotating shaft of the second motor 121 through the second connecting frame 122, and the second motor 121 can drive the second connecting frame 122 and the telescopic mechanism 13 to rotate around the rotating axis of the second motor 121. And the rotating axes of the first motor 111 and the second motor 121 are arranged vertically.

[0031] The telescopic mechanism 13 is used to drive the electroscope 2 to perform linear reciprocating motion. In some embodiments, the telescopic mechanism 13 can adopt a structural form of a power unit and a transmission unit, such as a common electric push rod, a cylinder, etc. The power unit drives the electroscope 2 to move through the transmission unit. In other embodiments, the telescopic mechanism 13 can also adopt a multi-stage power form, that is, multiple power units and multiple transmission units are connected in alternating transmission. For example, multiple electric push rods or cylinders are connected in sequence in the same direction, and each electric push rod or cylinder can output power simultaneously or sequentially to drive the electroscope 2 to move. This method can obtain a longer stroke under the condition that the stroke of a single transmission unit is limited.

[0032] like Figure 3 As shown, in this embodiment, the telescopic mechanism 13 includes a power unit 131 and a plurality of transmission units 132 that are sequentially connected in the same direction. One power unit 131 provides power, and a plurality of transmission units 132 transmit power, which can also break through the travel limit of a single transmission unit 132.

[0033] The second rotating mechanism 12 is connected to the power unit 131 in a transmission manner, that is, the rotating shaft of the second motor 121 is fixedly connected to the power unit 131 through the second connecting frame 122, so as to drive the second connecting frame 122 and the power unit 131 to rotate around the rotating axis of the second motor 121. The transmission units 132 at both ends are respectively connected to the power unit 131 and the electroscope 2, and the power unit 131 drives the electroscope 2 to move toward or away from the second rotating mechanism 12 through multiple transmission units 132.

[0034] In this embodiment, the power unit 131 includes a third motor 1311 and a winding frame 1312. The body of the third motor 1311 is fixedly connected to the second connecting frame 122. The rotating shaft of the third motor 1311 is fixedly connected to the winding frame 1312 to drive the winding frame 1312 to rotate.

[0035] Let the direction close to the power unit 131 be the front, and the direction close to the electroscope 2 be the rear. Figure 4 As shown, this embodiment includes two sets of transmission units: a head end transmission unit 132A connected to the power unit and a terminal transmission unit 132B connected to the electroscope.

[0036] The head end transmission unit 132A includes a fixed rod 1321A, a moving rod 1322A, a guide member 1323A, a traction rope 1324A, a first connecting body 1325A and a second connecting body 1326A.

[0037] In the head end transmission unit 132A, a guide member 1323A is fixedly provided at one end of the fixed rod 1321A. In this embodiment, the guide member 1323A adopts a fixed pulley. In some embodiments, the guide member 1323A can be installed through the second connecting body 1326A. That is, the fixed rod 1321A is fixedly connected to the second connecting body 1326A, and the guide member 1323A is arranged on the second connecting body 1326A and can rotate around the second connecting body 1326A. The other end of the fixed rod 1321A is fixedly connected to the power output end of the second rotating mechanism 12, and in some embodiments, it can be fixedly connected to the second connecting frame 122.

[0038] The traction rope 1324A passes through the guide member 1323A, one end of which is fixedly connected to the power output end of the power unit 131, and in this embodiment, is fixedly connected to the winding frame 1312, and the other end is fixedly connected to the movement rod 1322A, and is used to pull the movement rod 1322A to move. In this embodiment, the traction rope 1324A is connected to the movement rod 1322A through the first connector 1325A, that is, the first connector 1325A is fixedly connected to the traction rope 1324A and the movement rod 1322A.

[0039] In a preferred embodiment, the first connector 1325A has a through hole and is sleeved on the fixed rod 1321A, and the second connector 1326A also has a through hole and is sleeved on the moving rod 1322A. Through the guiding effect of the through holes on the first connector 1325A and the second connector 1326A, the moving rod 1322A can move in a direction parallel to the axis of the fixed rod 1321A.

[0040] The end transmission unit 132B has the same structure as the head transmission unit 132A, and also includes a fixed rod 1321B, a moving rod 1322B, a guide member 1323B, a traction rope 1324B, a first connector 1325B and a second connector 1326B.

[0041] One end of the fixed rod 1321B is connected to the guide member 1323B through the second connector 1326B, and the other end is fixedly connected to the first connector 1325A of the head end transmission unit 132A. The traction rope 1324B passes around the guide member 1323B, one end is fixedly connected to the first connector 1325A of the head end transmission unit 132A, and the other end is fixedly connected to the second connector 1326B through the first connector 1325B. One end of the moving rod 1322B is fixedly connected to the second connector 1326B, and the other end is connected to the electroscope 2. Similarly, in a preferred embodiment, the first connector 1325B is provided with a through hole and sleeved on the fixed rod 1321B, and the second connector 1326B is also provided with a through hole and sleeved on the moving rod 1322B. Through the guiding effect of the through holes on the first connector 1325B and the second connector 1326B, the moving rod 1322B can be moved along the axis parallel to the fixed rod 1321B.

[0042] When the third motor 1311 rotates and pulls the traction rope 1324A downward, the other end of the traction rope 1324A pulls up the first connector 1325A and the motion rod 1322A, and the motion rod 1322A moves upward to lift the terminal transmission unit 132B, and the guide member 1323B of the terminal transmission unit 132B moves upward relative to the second connector 1326A of the head transmission unit 132A. Since the traction rope 1324B of the terminal transmission unit 132B is fixed to the second connector 1326A of the head transmission unit 132A, the upward movement of the guide member 1323B relative to the second connector 1326A is equivalent to the downward movement of the second connector 1326A relative to the guide member 1323B, that is, the traction rope 1324B is pulled downward, thereby playing the same role as the power unit 131, and pulling up the motion rod 1322B.

[0043] It is easy to imagine that in other embodiments, a plurality of intermediate transmission units with the same structure can be further arranged between the head-end transmission unit 132A and the terminal transmission unit 132B in the same connection manner as between the terminal transmission unit 132B and the head-end transmission unit 132A.

[0044] Except for the head transmission unit 132A, the ends of the fixed rods of the other transmission units 132, i.e., the intermediate transmission unit and the terminal transmission unit 132B, which are away from the guide member, are fixedly connected to the moving rod of the previous transmission unit 132. The ends of the traction ropes of the intermediate transmission unit and the terminal transmission unit 132B, which are away from the moving rod, are fixedly connected to the fixed rod of the previous transmission unit.

[0045] In actual use, the equipment to be tested is located at a high position. If a single lifting device is used, a large stroke is required, which places high demands on the equipment and results in high equipment costs. However, the present application uses multiple transmission units 132 with small strokes to jointly achieve large-stroke lifting. When achieving the same function, the sum of the costs of multiple transmission units 132 is still less than that of a single large-stroke lifting device. In addition, the equipment to be tested is often not at the same height. By using the technical solution protected by the present application, the operator can choose the number of transmission units 132 according to actual conditions, which is more flexible to use.

[0046] It is easy to understand that only the fixed rod of the first transmission unit 132A is connected to the power output end of the second rotating mechanism 12, that is, in this embodiment, it is connected through the second connecting frame 122. The fixed rods of the subsequent other transmission units 132 are all fixedly connected to the first connecting body of the previous transmission unit 132, so as to keep synchronous movement with the moving rod of the previous transmission unit 132.

[0047] As for the moving rod, only the moving rod of the terminal transmission unit 132B is connected to the electroscope 2, and the moving rods of the remaining transmission units 132 are fixedly connected to the second connector of the next transmission unit 132, so as to keep synchronous movement with the fixed rod of the next transmission unit 132.

[0048] As for the traction rope, only one end of the traction rope of the first end transmission unit 132A is connected to the power output end of the power unit 131, that is, in this embodiment, it is connected through the winding frame 1312. The traction ropes of the subsequent other transmission units 132 are fixedly connected to the second connector of the previous transmission unit 132.

[0049] Since the detection object of the electroscope 2 generally has high voltage, in a preferred embodiment, the transmission unit 132 has insulation properties, and each component, namely the fixed rod, the moving rod, the guide member, the traction rope, the first connector and the second connector are all made of insulating materials.

[0050] The electroscope 2 is connected to the moving rod of the terminal transmission unit 132B. In a preferred embodiment, the electroscope 2 and the moving rod are connected in a detachable manner, such as threaded connection, snap-on connection, latch fixation, etc., so that operators can replace different models of electroscopes 2 as needed.

[0051] In other embodiments, the present invention provides an electrical testing device, which includes: a moving trolley 3 and the aforementioned electrical testing device, wherein the electrical testing device is arranged on the moving trolley 3, and the moving trolley 3 can carry the electrical testing device for movement.

[0052] The sports car 3 has the ability to drive automatically or by remote control, and can drive to the vicinity of the detected equipment by itself or by remote control of the operator, so that the operator can stay away from the high-voltage equipment more safely.

[0053] Therefore, in a preferred embodiment, a camera 4, a laser radar, an ultrasonic radar and other identification devices can also be installed on the sports car 3, so that the sports car 3 can identify and plan the path by itself, or for the operator to observe and better control the sports car 3 to travel to the working position.

[0054] After reaching the working position, the first rotating mechanism 11 and the second rotating mechanism 12 are controlled to rotate to a suitable angle, and the telescopic mechanism 13 is controlled to drive the electrician 2 to rise to a suitable height to carry out the electrician testing operation.

[0055] Compared with the prior art, the electroscope provided by the present invention drives the electroscope to move through a driver, and moves the electroscope to a detection position when the operator does not move, thereby avoiding the operator from having to perform operations at height.

[0056] The electric test equipment provided by the present invention moves to the vicinity of the tested equipment by carrying the electric test device through a moving trolley, and then drives the electric tester to the testing position through a driver, so that the operator can complete the electric test work away from the high-voltage testing equipment, reducing the safety risk of the operator.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
