[0036] Unless otherwise stated, the term "plurality" means two or more.

[0037] In the prior art, a high-voltage tester includes a test head and an insulating rod, and the test head is connected to one end of the insulating rod. The test head is used to contact the object to be tested to detect whether the object to be tested is energized. High-voltage electrical equipment is usually installed at a higher position from the ground. The middle area on the top surface of the high-voltage electrical equipment is usually provided with high-voltage wires or hardware. When testing the high-voltage wires or hardware, the operator needs to stand on the ground, hold the insulating rod, and tilt the insulating rod toward the high-voltage wire or hardware, for example, so that the angle between the insulating rod and the vertical direction is 45 degrees, so that the test head is in contact with the high-voltage wire or hardware. However, the test head is usually located on the same straight line as the insulating rod. When the insulating rod is tilted, the test head is not easy to contact the high-voltage wire or hardware, resulting in a longer time required for the test, which affects the test efficiency of the high-voltage tester.

[0038] Based on this, the embodiment of the present application provides an electric test device, including a support rod, a transmission assembly and at least one electric tester, the electric tester includes an insulating rod and an electric tester, and the transmission assembly includes a transmission rod and at least one first transmission member. The electric tester contacts the device to be tested to detect whether the device to be tested is energized. By setting a support rod to support the transmission assembly, when the height of the device to be tested is high, the length of the electric test device can be increased, so as to facilitate the contact between the electric tester and the device to be tested. The transmission rod is connected to the insulating rod, the first transmission member is connected to the transmission rod, and the first transmission member rotates relative to the support rod, so as to drive the insulating rod to rotate relative to the support rod through the transmission rod, and then drive the electric tester to rotate relative to the support rod, thereby changing the angle between the electric tester and the support rod. When testing electricity, the angle between the electric tester and the support rod can be adjusted to a more suitable angle according to the position of the device to be tested, so that the electric tester faces the device to be tested, thereby facilitating the contact between the electric tester and the device to be tested, reducing the operation time of the electric test, and improving the efficiency of the electric test.

[0039] The embodiments of the present application are described below with reference to the accompanying drawings.

[0040] Figure 1 It is a structural schematic diagram of an electrical testing device provided in an embodiment of the present application; Figure 2 yes Figure 1 Schematic diagram of the structure of the electroscope and transmission components; Figure 3 yes Figure 2 A schematic diagram of the structure from another perspective.

[0041] Reference Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides an electric test device, including: a support rod 200, a transmission assembly 300 and at least one electric tester 100. The electric tester 100 includes an insulating rod 110 and an electric tester 120 connected to the insulating rod 110, and the electric tester is used to contact the device under test to detect whether the device under test is charged.

[0042] The transmission assembly 300 includes a transmission rod 310 and at least one first transmission member 320, the transmission rod 310 is connected to the first transmission member 320, the first transmission member 320 is located in the support rod 200, the transmission rod 310 partially extends out of the support rod 200, and is detachably connected to the insulating rod 110, and the first transmission member 320 is configured to rotate relative to the support rod 200 so as to drive the insulating rod 110 to rotate relative to the support rod 200 through the transmission rod 310.

[0043] The electric test component 120 is provided with an audible and visual alarm component. When the electric test component 120 detects that the device to be tested is energized, the audible and visual alarm component will send out an alarm signal.

[0044] In some embodiments, the electrical testing device further includes a warning member, which is in communication with the sound and light alarm member, and the sound and light alarm member transmits the alarm signal to the warning member. Specifically, the operator can place the warning member at a position close to the operator to facilitate obtaining the alarm signal.

[0045] When testing electricity, the voltage level of the tester 100 must be consistent with the voltage level of the device to be tested to avoid misjudgment or safety accidents. Therefore, the tester device includes at least one tester 100, and the voltage level of each tester 100 is different. For example, the voltage level can be 10kV, 35kV, 110kV, 220kV, 500kV, etc. The insulating rod 110 and the transmission rod 310 are detachably connected, so that when testing devices with different voltage levels, the tester 100 that matches the voltage level of the device can be replaced. It can be understood that the connection between the insulating rod 110 and the transmission rod 310 can be a threaded connection or a snap-on connection.

[0046] Exemplarily, the electrical testing device further includes a connecting member, the transmission rod 310 has a first connecting hole, the insulating rod 110 has a second connecting hole, and the connecting member is connected to the second connecting hole via the first connecting hole. For example, the connecting member is a screw.

[0047] In some embodiments, the insulating rod 110 includes a plurality of insulating segments, and the diameter of each insulating segment decreases successively so that each insulating segment is nested in sequence. The insulating segment with the largest diameter is connected to the transmission rod 310, and the insulating rod with the smallest diameter is connected to the tester 120. Thus, the length of the insulating rod 110 can be adjusted by nesting or connecting two adjacent insulating segments, and then the length of the tester 100 can be adjusted, thereby expanding the adjustable range of the length of the tester and improving the applicability of the tester. Exemplarily, the length of the insulating segment is 0.5 m, and the number of insulating segments is three.

[0048] The support rod 200 is an insulating support rod, and a hand-held portion is provided on the support rod 200. The hand-held portion is located on a side of the support rod 200 away from the electroscope 100 to improve the safety of the electroscope. When performing the electroscope test, the operator can hold the hand-held portion. For example, the hand-held portion is made of insulating rubber material.

[0049] In a specific implementation, the first transmission member 320 is rotated relative to the support rod 200, so that the transmission rod 310 is rotated relative to the support rod 200, and the transmission rod 310 drives the insulating rod 110 to rotate relative to the support rod 200, thereby enabling the electroscope 100 to rotate relative to the support rod 200. Therefore, when using the electroscope device, the electroscope 100 can be rotated relative to the support rod 200 to adjust the electroscope 100 to a more suitable position, so as to facilitate the electroscope 100 to test the electricity.

[0050] When testing high-voltage wires or hardware on the top surface of high-voltage electrical equipment, the operator can first rotate the electroscope 100 relative to the support rod 200 so that the angle between the electroscope 100 and the support rod 200 is less than or equal to 90°, and then when the electroscope 100 is close to the high-voltage electrical equipment, the electroscope 120 is more likely to face the top surface of the high-voltage electrical equipment. After that, the operator can hold the support rod 200 and make the electroscope 120 of the electroscope 100 close to the top surface of the high-voltage electrical equipment to complete the test.

[0051] It should be noted that the length of the support rod 200 can be adaptively set according to actual needs, so that the operator can hold the support rod 200 to make the electroscope 100 contact the device under test, and this embodiment does not limit this. For example, the length of the support rod 200 is equivalent to the height of the device under test.

[0052] The electric test device provided in the embodiment of the present application is to contact the device under test with the electric test piece 120 to detect whether the device under test is charged. The support rod 200 is provided to support the transmission assembly 300. At the same time, when the height of the device under test is high, the length of the electric test device can be increased, so as to facilitate the contact between the electric test piece 120 and the device under test. The transmission rod 310 is connected to the insulating rod 110, and the first transmission piece 320 is connected to the transmission rod 310. The first transmission piece 320 rotates relative to the support rod 200, so as to drive the insulating rod 110 to rotate relative to the support rod 200 through the transmission rod 310, and then drive the electric tester 100 to rotate relative to the support rod 200, so as to adjust the angle between the electric tester 100 and the support rod 200. When testing electricity, the angle between the electric tester 100 and the support rod 200 can be adjusted to a more suitable angle according to the position of the device under test, so that the electric test piece 120 faces the device under test, so as to facilitate the contact between the electric test piece 120 and the device under test, thereby reducing the operation time of the electric test and improving the efficiency of the electric test.

[0053] Figure 4 yes Figure 2 A schematic diagram of the structure of the first transmission member, the second transmission member and the transmission rod; Figure 5 yes Figure 4 A structural diagram from another perspective; Figure 6 yes Figure 5 Schematic diagram of the structure of the first transmission member.

[0054] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the transmission assembly 300 also includes a second transmission member 330, which is located in the support rod 200 and is rotatably connected to the support rod 200, and the first transmission member 320 has at least one first plug-in portion 324, and the second transmission member 330 has at least one second plug-in portion 333.

[0055] The second transmission member 330 is configured to rotate relative to the support rod 200 to enable the second plug-in portion 333 to be plugged into or disengaged from the first plug-in portion 324 , and when the second plug-in portion 333 is plugged into the first plug-in portion 324 , the first transmission member 320 is driven to rotate relative to the support rod 200 .

[0056] The support rod 200 is in a sleeve shape, and the first transmission member 320 and the second transmission member 330 are both located in the support rod 200 to facilitate the plugging of the first plug-in portion 324 and the second plug-in portion 333 .

[0057] It is understandable that the transmission rod 310, the first transmission member 320 and the second transmission member 330 are all made of insulating materials to ensure the safety of electrical testing. For example, the transmission rod 310, the first transmission member 320 and the second transmission member 330 can be made of insulating resin material.

[0058] Specifically, the second transmission member 330 rotates relative to the support rod 200 so that the second plug-in portion 333 rotates relative to the support rod 200. When the second plug-in portion 333 rotates to be plugged with the first plug-in portion 324, the second plug-in portion 333 continues to rotate to drive the first plug-in portion 324 to rotate relative to the support rod 200, thereby driving the first transmission member 320 to rotate relative to the support rod 200. When the second plug-in portion 333 rotates to be disengaged from the first plug-in portion 324, the first plug-in portion 324 stops rotating, thereby causing the first transmission member to stop rotating. It is understandable that the second transmission member 330 can drive the first transmission member 320 to rotate by a preset angle every time it rotates one circle.

[0059] In some embodiments, the first transmission member 320 and the second transmission member 330 may both be gears, and the first transmission member 320 is meshingly connected with the second transmission member 330 .

[0060] Reference Figure 1 , Figure 4 and Figure 6 As shown, in some embodiments, the number of the first transmission members 320 is two, the two first transmission members 320 are arranged in parallel and spaced apart, and the first transmission member 320 is coaxially connected to the transmission rod 310 .

[0061] The second plug-in portion 333 is configured to be connected to and disconnected from the first plug-in portion 324 on one of the first transmission members 320, driving the first transmission member 320 to rotate by a preset angle in a first direction, and to be connected to and disconnected from the first plug-in portion 324 on the other first transmission member 320, driving the first transmission member 320 to rotate by a preset angle in a second direction opposite to the first direction.

[0062] The second transmission member 330 is located on one side of the first transmission member 320 , the axis of the second transmission member 330 is perpendicular to the axis of the first transmission member 320 , and the two first transmission members 320 are respectively opposite to the upper and lower parts of the second transmission member 330 .

[0063] Specifically, the initial position of the electroscope 100 is the first position. The second transmission member 330 rotates relative to the support rod 200 in a preset direction so that the second plug-in portion 333 is plugged into the first plug-in portion 324 on one of the first transmission members 320, thereby driving the first transmission member 320 to rotate relative to the support rod 200 in the first direction. The second transmission member 330 continues to rotate relative to the support rod 200 in a preset direction so that the second plug-in portion 333 is disconnected from the first plug-in portion 324 on the first transmission member 320. In the process of the second plug-in portion 333 and the first plug-in portion 324 on the first transmission member 320 being plugged in and disconnected from each other, the first transmission member 320 rotates relative to the support rod 200 in the first direction by a preset angle, so as to drive the electroscope 100 to rotate in the first direction by a preset angle through the transmission rod 310, thereby rotating the electroscope 100 from the first position to the second position.

[0064] The second transmission member 330 rotates in a preset direction relative to the support rod 200, so that the second plug-in portion 333 is plugged into the first plug-in portion 324 on the other first transmission member 320. The second transmission member 330 continues to rotate in a preset direction relative to the support rod 200, so that the second plug-in portion 333 is disengaged from the first plug-in portion 324 on the first transmission member 320. In the process of the second plug-in portion 333 and the first plug-in portion 324 on the first transmission member 320 being plugged into and disengaged from each other, the first transmission member 320 rotates in a preset angle in the second direction relative to the support rod 200, so as to drive the electroscope 100 to rotate in the second direction by a preset angle through the transmission rod 310, thereby rotating the electroscope 100 from the second position to the first position.

[0065] It can be understood that one of the first direction and the second direction is a clockwise direction, and the other is a counterclockwise direction. The preset direction is one of the clockwise direction and the counterclockwise direction.

[0066] Exemplarily, the preset angle is 90°, and the second transmission member 330 rotates one circle relative to the support rod 200, and can drive one of the first transmission members 320 to rotate 90° along the first direction relative to the support rod 200 through the first plug-in portion 324 and the second plug-in portion 333, and drive the other first transmission member 320 to rotate 90° along the second direction relative to the support rod. Thus, the first transmission member 320 can drive the electroscope 100 to rotate between the horizontal position and the vertical position through the transmission rod 310. It should be noted that the preset angle can also be 60°, 120°, 150°, 180°, etc., and can be set adaptively according to actual needs.

[0067] In this way, by setting two first transmission members 320, the second transmission member 330 can be rotated along the preset direction to make the two first transmission members 320 rotate by the preset angles in the first direction and the second direction respectively, and then the transmission rod 310 can be used to drive the electroscope 100 to rotate by the preset angle in the first direction or the second direction, so that the electroscope 100 can be rotated between the first position and the second position.

[0068] In some embodiments, one of the first plug-in portion 324 and the second plug-in portion 333 is a plug-in rod, and the other is a plug-in socket matching the plug-in rod.

[0069] Specifically, the plug rod is plugged into the plug hole so that the second transmission member 330 drives the first transmission member 320 to rotate. The plug connection is relatively simple and convenient and easy to implement.

[0070] Reference Figure 5 and Figure 6 As shown, in a specific implementation, the first plug-in portion 324 is a socket. The first transmission member 320 includes two parallel connecting plates 321 and a plurality of connecting rods 323, the connecting rods 323 are located between the two connecting plates 321 and connected to the two connecting plates 321, each connecting rod 323 is arranged at intervals around the circumference of the connecting plate 321, and a socket is formed between two adjacent connecting rods 323.

[0071] Among them, there is a fixing hole 322 on the connecting plate 321, the center of the fixing hole 322 is located on the axis of the connecting plate 321, and the transmission rod 310 is inserted into the fixing holes 322 of the two connecting plates 321 in sequence and fixedly connected to the fixing holes 322, so that the transmission rod 310 is fixedly connected to the first transmission member 320.

[0072] Each connecting rod 323 is evenly spaced so that each jack has the same size. Each connecting rod 323 is far away from the fixing hole 322 so that the jack is far away from the fixing hole 322, which is convenient for the rod to be plugged into the jack.

[0073] Specifically, the insertion rod is located on the second transmission member 330, and the second transmission member 330 rotates relative to the support rod 200 so that the insertion rod is plugged into the socket, thereby driving the connecting rod 323 to rotate relative to the support rod 200, and the connecting rod 323 drives the connecting plate 321 to rotate relative to the support rod 200, and the connecting plate 321 drives the transmission rod 310 to rotate relative to the support rod 200.

[0074] Reference Figure 1 , Figure 4 and Figure 5The second transmission member 330 includes a first mounting shaft 331 and a first circular plate 332 , wherein the first mounting shaft 331 connects the center of the first circular plate 332 with the support rod 200 , and the plugging rod is disposed on a surface of the first circular plate 332 facing the first transmission member 320 .

[0075] The insertion rod is connected to a surface of the first circular plate 332 facing the first transmission member 320 , so that the insertion rod can be inserted into the insertion hole on the first transmission member 320 .

[0076] The first installation axis 331 is located between the two first transmission members 320, and the distance between the first installation axis 331 and the two first transmission members 320 is equal, so that the projections of the two first transmission members 320 on the first circular plate 332 are symmetrical, so that the second transmission member 330 drives the two first transmission members 320 to rotate at equal angles.

[0077] Exemplarily, the first mounting shaft 331 is fixedly connected to the support rod 200, and the center of the first circular plate 332 is rotatably connected to the first mounting shaft 331, so that the connection between the second mounting shaft 341 and the support rod 200 is more stable. At the same time, the first circular plate 332 can rotate relative to the support rod 200, and the insertion rod is arranged on the first circular plate 332, which can drive the insertion rod to rotate relative to the first mounting shaft 331, so that the insertion rod can be plugged into or out of the socket.

[0078] In a specific implementation, the number of the insertion rods is at least two, and the insertion rods are arranged at intervals along the circumference of the first circular plate 332 , and the distance between two adjacent insertion rods is equivalent to the distance between two adjacent connecting rods 323 .

[0079] The insertion rods are evenly spaced and at least part of the insertion holes are located on the rotation track of the insertion rods, so that the insertion rods can be easily inserted into the insertion holes when the insertion rods rotate.

[0080] It can be understood that the spacing between two adjacent insertion rods is equivalent to the spacing between two adjacent connecting rods 323, which means that the spacing between two adjacent insertion rods and the spacing between two adjacent connecting rods 323 can be equal, or there can be a smaller gap, so that at least two insertion rods can be inserted into the socket at the same time.

[0081] Exemplarily, the number of the plugging rods is three, and the three plugging rods are arranged at intervals on the first circular plate 332, the number of the connecting rods 323 is sixteen, and the number of the plugging holes is sixteen.

[0082] Reference Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the transmission assembly 300 also includes a second circular plate 340 and a transmission belt 350. The second circular plate 340 is rotatably set on the support rod 200. The transmission belt 350 connects the first circular plate 332 and the second circular plate 340. The second circular plate 340 rotates relative to the support rod 200 to drive the first circular plate 332 to rotate relative to the support rod 200.

[0083] Among them, when inspecting high-voltage electrical equipment, since the height of the high-voltage electrical equipment is usually high, the support rod 200 is also usually long. The first circular plate 332 is close to one end of the support rod 200, and the hand-held part is located on the end of the support rod 200 away from the first circular plate 332. The hand-held part is far away from the first circular plate 332, making it more inconvenient for the first circular plate 332 to rotate relative to the support rod 200.

[0084] Therefore, a second circular plate 340 is rotatably provided on one side close to the handheld portion, and the first circular plate 332 and the second circular plate 340 are respectively close to the two ends of the support rod 200. The first circular plate 332 and the second circular plate 340 are connected by a transmission belt 350. By rotating the second circular plate 340 relative to the support rod 200, the first circular plate 332 can be driven to rotate relative to the support rod 200 through the transmission belt 350. Therefore, when the operator holds the handheld portion to test electricity, it is more convenient to rotate the first circular plate 332 relative to the support rod 200, thereby facilitating the rotation of the electroscope 100 relative to the support rod 200.

[0085] It is understandable that the second transmission member 330, the second circular plate 340 and the transmission belt 350 are all located in the support rod 200, so that the first circular plate 332 and the second circular plate 340 are connected through the transmission belt 350, and the insertion rod and the socket are plugged in more conveniently.

[0086] In a specific implementation, a second installation shaft 341 and a handle 342 are provided on the second circular plate 340 . The second installation shaft 341 connects the center of the second circular plate 340 and the support rod 200 , and the handle 342 is connected to the second installation shaft 341 .

[0087] Exemplarily, the second mounting shaft 341 is fixedly connected to the support rod 200, and the center of the second circular plate 340 is rotatably connected to the second mounting shaft 341, so that the second circular plate 340 can rotate relative to the support rod 200, and the connection between the second mounting shaft 341 and the support rod 200 is relatively stable.

[0088] The second installation axis 341 is partially located outside the support rod 200, and the handle 342 is connected to the part of the second installation axis 341 located outside the support rod 200, so that by rotating the handle 342 relative to the support rod 200, the second circular plate 340 can be driven to rotate relative to the support rod 200, which is relatively simple and convenient to operate.

[0089] It is understandable that the shape of the handle 342 can be I-shaped, L-shaped, Z-shaped or other shapes to facilitate the handle 342 to rotate relative to the support rod 200, and this embodiment does not limit this.

[0090] Furthermore, when the handle 342 is I-shaped, the handle 342 is perpendicular to the second installation shaft 341 so that the handle 342 can drive the second installation shaft 341 to rotate.

[0091] In some embodiments, the electroscope device further includes a limiting rod, a first limiting hole is provided on the handle 342, and a plurality of second limiting holes are provided on the support rod 200, and each second limiting hole is arranged around the circumference of the second mounting shaft 341. When the handle 342 is rotated relative to the support rod 200 until the electroscope 100 is located at a more suitable position, the limiting rod is inserted into the second limiting hole through the first limiting hole to fix the handle 342 at the current position, thereby preventing the handle 342 from rotating relative to the support rod 200, and thus fixing the electroscope 100 at the current position.

[0092] Exemplarily, the distance between the first limiting hole and the second mounting shaft 341 is equal to the distance between the second limiting hole and the second mounting shaft 341, so that the limiting rod is inserted into the second limiting hole through the first limiting hole. The second limiting holes are evenly arranged around the circumference of the second mounting shaft 341, and the number of the second limiting holes is equal to the number of the connecting rods 323 on the first transmission member 320.

[0093] Figure 7 yes Figure 1 Schematic diagram of the structure of the middle support rod.

[0094] Reference Figure 1 , Figure 2 and Figure 7 As shown, in some embodiments, the support rod 200 includes a plurality of support segments 210, and the diameter of each support segment 210 decreases sequentially, so that each support segment 210 is nested sequentially.

[0095] Among them, by setting a plurality of support sections 210, the length of the support rod 200 can be adjusted by connecting the ends of two adjacent support sections 210 or nesting one in the other. When using the electrical testing device, the length of the support rod 200 can be adjusted according to the height of the device to be tested, which facilitates the contact between the electrical tester 100 and the device to be tested, thereby improving the applicability of the electrical testing device.

[0096] For example, the handheld portion is located on the support section 210 with the largest diameter, so that the operator can hold the handheld portion easily. The transmission rod 310 is inserted into the support section 210 with the smallest diameter, so that when the operator holds the handheld portion, the transmission rod 310 and the electroscope 100 are far away from the handheld portion, ensuring the safety of the electrical test and facilitating the contact between the electroscope 100 and the device to be tested.

[0097] Specifically, the support rod 200 has two avoidance holes 211, and the transmission rod 310 is inserted into the two avoidance holes 211 and is rotatably connected to the avoidance holes 211, so that the transmission rod 310 can rotate relative to the support rod 200, and the connection between the transmission rod 310 and the support rod 200 is relatively stable. Further, two limiters can be provided on the transmission rod 310, and the two limiters are both sleeved on the transmission rod 310, and the two limiters are respectively located on the same side of the two avoidance holes 211, and the same side of the avoidance holes 211 refers to a side located inside the support rod 200 or a side located outside the support rod 200, and the limiters abut against the side wall of the support rod 200 to limit the transmission rod 310 and prevent the transmission rod 310 from moving relative to the support rod 200.

[0098] Furthermore, the first circular plate 332 is connected to the support section 210 with the smallest diameter, and the second circular plate 340 is connected to the support section 210 with the largest diameter. When the length of the support rod 200 changes, the distance between the first circular plate 332 and the second circular plate 340 changes. Therefore, the transmission belt 350 can be made of rubber material to ensure that the connection between the transmission belt 350 and the first circular plate 332 and the second circular plate 340 is relatively tight when the distance between the first circular plate 332 and the second circular plate 340 changes. It should be noted that the transmission belt 350 can also be made of other highly elastic, stretchable and shrinkable materials.
