Description

Technical Field

[0001] This invention relates to the field of power technology, and more particularly to radio frequency power metering terminal detection. Background Technology

[0002] Electricity metering terminals are prone to malfunction after prolonged use. To prevent malfunctions or to facilitate timely repairs after they occur, testing devices are needed to inspect the terminals. Some metering terminals are installed at a high height, requiring ladders for inspection. However, this makes it inconvenient for workers to retrieve and use the testing devices while standing on the ladder.

[0003] In electronics theory, when an electric current flows through a conductor, a magnetic field is formed around the conductor; when alternating current flows through a conductor, an alternating electromagnetic field is formed around the conductor, which is also called an electromagnetic wave. Electromagnetic waves with frequencies below 100kHz are absorbed by the Earth's surface and cannot achieve effective transmission. However, when the frequency is above 100kHz, electromagnetic waves can propagate through the air and be reflected by the ionosphere at the outer edge of the atmosphere, enabling long-distance transmission. We call high-frequency electromagnetic waves with long-distance transmission capabilities radio frequency (RF), and the RF frequency range is 300kHz to 300GHz.

[0004] Radio frequency (RF) technology is widely used in the field of wireless communication. Existing technology, patent application number CN202021619565.5, discloses an RF-type electricity metering terminal testing device, including a testing body. A connecting block is fixedly connected to one side of the testing body, and a tray is rotatably connected inside the connecting block. Connecting straps are fixedly connected to both sides of the tray. One side of one connecting strap is fixedly connected to a first hook-and-loop fastener, and the other side of the connecting strap is fixedly connected to a second hook-and-loop fastener. In use, this device can be fixed to the operator's wrist by the first and second hook-and-loop fasteners. After the operator climbs to the metering terminal, they can test the metering terminal.

[0005] However, the above solution uses hook and loop fasteners to secure the device to the worker's wrist. During work at heights, the fasteners may loosen, posing a risk of equipment damage or personal injury. Furthermore, because the device is fixed to the wrist, single-handed operation is inconvenient during inspections at heights. Summary of the Invention

[0011] A detection head is located at the top of the telescopic assembly and connected to the detection machine. The detection head can be inserted into or removed from the positioning box through the detection hole.

[0018] As an optional technical solution for a radio frequency power metering terminal detection device, the first gear is provided on both sides of the second telescopic rod, and the bar hole, the first rack and the second rack are all provided in a one-to-one correspondence with the first gear.

[0019] As an optional technical solution for a radio frequency energy metering terminal testing device, the lower end of the telescopic component is rotatably connected to the testing machine, and the rotation axis of the telescopic component is set along the second direction.

[0020] As an optional technical solution for a radio frequency energy metering terminal detection device, the device is characterized in that a connecting rod is rotatably installed at the top of each telescopic component, the connecting rod extends along a second direction and can rotate around the second direction, and the positioning box is connected between the two connecting rods.

In other words, the RF energy metering terminal testing device provided by this invention allows operators to test energy metering terminals from the ground without climbing, reducing workload and ensuring a safe testing process.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0044] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0047] Example 1:

[0048] To enable staff to inspect energy metering terminals installed at high locations from the ground, this embodiment provides a radio frequency energy metering terminal inspection device, which is described below in conjunction with... Figures 1-7 This embodiment will be described in detail.

[0049] like Figure 1As shown, in this embodiment, the radio frequency energy metering terminal detection device includes a detection machine 1, a telescopic component 2, a positioning box 3, and a detection head 4. The telescopic component 2 can extend and retract along a first direction and its lower end is connected to the detection machine 1. Two sets of the telescopic components 2 are spaced apart along a second direction, which is horizontal and perpendicular to the first direction. The positioning box 3 is open-ended and has a detection hole 31 through one side wall. The positioning box 3 is connected between the top ends of the two telescopic components 2 and is rotatably connected to the telescopic components 2. The rotation axis of the positioning box 3 is set along the second direction. The detection head 4 is disposed at the top end of one of the telescopic components 2 and is connected to the detection machine 1. The detection head 4 can be inserted into or removed from the positioning box 3 through the detection hole 31.

[0050] The radio frequency (RF) energy metering terminal testing device provided in this embodiment, through the inclusion of a telescopic component 2, allows operators to place the positioning box 3 and the testing head 4 near the energy metering terminal being tested while standing on the ground. Because the positioning box 3 and the telescopic component 2 are rotatably connected, when the positioning box 3 is raised to the vicinity of the energy metering terminal, its rotation allows for better contact with the terminal, effectively improving the testing success rate. After the positioning box 3 is properly engaged, the operator controls the testing head 4 to insert into the positioning box 3 and connect it to the energy metering terminal. This allows the testing machine 1 to collect information from the energy metering terminal using RF technology, enabling operators to test energy metering terminals located at higher elevations from the ground. After testing, the testing head 4 retracts from the positioning box 3, preventing collisions between the energy metering terminal and the testing head 4 when it comes out of the box, significantly reducing the possibility of damage to the testing head 4.

[0051] In this embodiment, the testing machine 1 includes a chassis, a display screen on the front surface of the chassis, several evenly distributed buttons on one side of the display screen, several evenly distributed indicator lights on the other side of the display screen, and several evenly distributed testing line interfaces on the rear side of the chassis. Operators use the buttons to operate the radio frequency energy metering terminal for testing. The indicator lights indicate the working status, and the testing results are displayed on the display screen. The testing head 4 is connected to the testing head 4 via a connecting wire between the testing line interfaces at the rear of the testing machine 1 and the testing head 4.

[0052] It is worth noting that the detection machine 1 and the detection head 4 provided in this embodiment are both existing mature products. The structure of the detection machine 1, the structure of the detection head 4, the connection between the detection machine 1 and the detection head 4, and the detection principle of the detection machine 1 for the electricity metering terminal are all existing technologies. This is not the focus of this invention and will not be elaborated here.

[0053] In this embodiment, the lower end of the telescopic component 2 is rotatably connected to the testing machine 1, and the rotation axis of the telescopic component 2 is set along the second direction. During use, when the telescopic component 2 extends to the working position, the operator does not need to move the radio frequency energy metering terminal testing device. They only need to rotate the telescopic component 2 to bring the positioning box 3 close to the energy metering terminal, which effectively improves work efficiency and enhances the flexibility and convenience of using the testing device.

[0054] Each telescopic component 2 has a connecting rod 6 rotatably mounted at its top. The connecting rod 6 extends along a second direction and can rotate around that direction. The positioning box 3 is installed between the two connecting rods 6. The detection head 4 is slidably mounted on the connecting rod 6 near the detection hole 31. The detection head 4 can move along the extension direction of the connecting rod 6, ensuring that the detection head 4 can smoothly enter the detection hole 31. The connecting rod 6 simplifies the connection between the positioning box 3 and the telescopic component 2 and facilitates the sliding of the detection head 4 along the second direction.

[0055] like Figure 2 As shown, each telescopic rod assembly further includes a first telescopic rod 21, a second telescopic rod 22, and a third telescopic rod 23. The lower end of the first telescopic rod 21 is connected to the testing machine 1. The second telescopic rod 22 is slidably installed inside the first telescopic rod 21 and can move along a first direction and extend beyond the top of the first telescopic rod 21. The third telescopic rod 23 is slidably installed inside the second telescopic rod 22 and can move along a first direction and extend beyond the top of the second telescopic rod 22. The testing head 4 and the positioning box 3 are connected to the top of the third telescopic rod 23. By setting the above-mentioned two-stage telescopic device, compared with the ordinary single-stage telescopic device, while ensuring the extension length of the telescopic assembly 2, the external volume of the testing device when retracted can be effectively reduced, making it more convenient for staff to carry.

[0056] like Figure 3 and Figure 4As shown, further, a first motor 24 is provided at the bottom of the first telescopic rod 21, and the output shaft of the first motor 24 is arranged along a first direction. A lead screw 25 extending along the first direction is rotatably installed inside the first telescopic rod 21. The second telescopic rod 22 is provided with a threaded hole 221 along the first direction. The lead screw 25 cooperates with the threaded hole 221 for transmission, and the bottom end of the lead screw 25 is connected to the output shaft of the first motor 24. The top end of the lead screw 25 extends into the interior of the second telescopic rod 22. When the motor starts to drive the lead screw 25 to rotate, the cooperation between the lead screw 25 and the threaded hole 221 allows the second telescopic rod 22 to extend and retract within the first telescopic rod 21, thereby adjusting the length of the telescopic assembly 2 so that the positioning box 3 and the detection head 4 can move closer to or further away from the electricity metering terminal. The second telescopic rod 22 is driven by a first motor 24 and a lead screw 25. The drive structure is located inside the first telescopic rod 21, which effectively controls the volume of the telescopic component 2. With the above configuration, the operator can control the extension and retraction of the second telescopic rod 22 by controlling the first motor 24 to rotate forward or backward, which is simple and convenient.

[0057] like Figures 3-6 As shown, one of the second telescopic rod 22 and the third telescopic rod 23 is equipped with a first rack 231, and the other is rotatably mounted with a first gear 26. The first rack 231 extends along a first direction and meshes with the gear. The rotation of the first gear 26 drives the first rack 231 to move, allowing the third telescopic rod 23 to extend and retract within the second telescopic rod 22. This configuration results in a compact transmission structure, effectively controlling the volume of the telescopic assembly 2, and also fits the aforementioned structure where the second telescopic rod 22 is located inside the first telescopic rod 21, achieving controllable extension and retraction of the third telescopic rod 23 within a limited space.

[0058] In this embodiment, the first gear 26 is disposed on the second telescopic rod 22, and the first rack 231 is disposed on the third telescopic rod 23. In other embodiments, the first gear 26 may also be disposed on the third telescopic rod 23, and the first rack 231 may be disposed inside the second telescopic rod 22.

[0059] Preferably, the side wall of the second telescopic rod 22 is provided with a through hole 222 along the first direction. The first gear 26 is installed in the through hole 222, and the first rack 231 is installed on the outside of the third telescopic rod 23. A second rack 211 is also provided on the inner wall of the first telescopic rod 21, and the second rack 211 meshes with the first gear 26. Since both the second rack 211 and the first rack 231 mesh with the first gear 26, when the second telescopic rod 22 and the first telescopic rod 21 move relative to each other, the second rack 211 drives the first gear 26 to rotate, and then the first gear 26 drives the first rack 231 to rotate, causing the third telescopic rod 23 and the second telescopic rod 22 to move relative to each other.

[0060] A simple derivation reveals that when the second telescopic rod 22 moves away from (or closer to) the first telescopic rod 21, the third telescopic rod 23 also moves away from (or closer to) the second telescopic rod 22. Therefore, by configuring the above structure, synchronous telescopic movements of the second telescopic rod 22 and the third telescopic rod 23 can be achieved, improving the convenience and efficiency of telescopic adjustment of the telescopic assembly 2. By driving the second telescopic rod 22 with the first motor 24, the entire telescopic assembly 2 can be controlled, effectively simplifying the operation, reducing driving costs, and improving the reliability of the detection device.

[0061] In other embodiments, the second telescopic rod 22 and the third telescopic rod 23 can be driven to extend and retract independently. The second rack 211 is not provided; instead, the first gear 26 is connected to the power unit, driving the first rack 231 to extend and retract independently. This allows for two-stage extension and retraction of the telescopic assembly 2 through the separate extension and retraction control of the second and third telescopic rods 22 and 23. Thus, when the electricity metering terminal is positioned low, staff only need to drive a portion of the telescopic assembly 2 to move the positioning box 3 near the electricity metering terminal.

[0062] Furthermore, a first gear 26 is provided on each of the opposite sides of the second telescopic rod 22, and the slot 222, the first rack 231, and the second rack 211 correspond one-to-one with the first gear 26. By providing two sets of the aforementioned gear and rack transmission structure, the transmission process becomes more stable during the movement of the telescopic assembly 2, reducing the possibility of the telescopic assembly 2 jamming, while also reducing friction and extending the service life of the telescopic assembly 2.

[0063] Specifically, the first telescopic rod 21, the second telescopic rod 22, and the third telescopic rod 23 are all square rods. The square rods can restrict the relative sliding between two adjacent telescopic rods and prevent rotation, thus ensuring the normal operation of the telescopic assembly 2.

[0064] like Figure 7 As shown, specifically, a connecting assembly 5 is provided on the connecting rod 6 near the detection hole 31. The connecting assembly 5 includes a third rack 52, a slider 53, a second motor 55, and a second gear 54. The third rack 52 is positioned on the connecting rod 6 along a second direction, the slider 53 is slidably positioned on the connecting rod 6 along the second direction, the detection head 4 is mounted on the slider 53, the second motor 55 is mounted on the slider 53, and the second gear 54 is connected to the output shaft of the second motor and meshes with the third rack 52. By controlling the second motor 55 to rotate forward or reverse, the operator can control the slider 53 to move horizontally on the connecting rod 6, causing the detection head 4 to penetrate into the detection hole 31. The control method is simple, and the structure is small in size.

[0065] The connecting assembly 5 also includes a mounting rod 51, which is detachably connected to the connecting rod 6. The third rack 52 is mounted on the mounting rod 51, and the slider 53 is slidably connected to the slide rail of the connecting rod 6. Through the above settings, the entire connecting assembly 5 can be quickly assembled and disassembled.

[0066] Example 2:

[0067] This embodiment provides a radio frequency energy metering terminal detection device. Compared with Embodiment 1, the radio frequency energy metering terminal detection device provided in this embodiment has a basically the same structure, except that the telescopic component 2 is different. This embodiment will not describe the same structure as Embodiment 1 again.

[0068] Two sets of telescopic components 2 are arranged at intervals along the second direction. Each set of telescopic components 2 includes a first telescopic rod 21, a second telescopic rod 22, and a third telescopic rod 23. The lower end of the first telescopic rod 21 is rotatably connected to the testing machine 1, and the top of the third telescopic rod 23 is rotatably connected to the positioning box 3. The second telescopic rod 22 is slidably connected inside the first telescopic rod 21, and the third telescopic rod 23 is slidably connected inside the second telescopic rod 22. A locking device is provided between two adjacent connecting rods 6.

[0069] Specifically, when storing the radio frequency (RF) energy metering terminal testing device, the telescopic component 2 is in a retracted state. When using the RF energy metering terminal testing device, the telescopic component 2 is in an extended state. The operator manually pulls out the second telescopic rod 22 and the third telescopic rod 23, and uses a locking device to lock the relative positions of the two adjacent telescopic rods, so that the positioning box 3 at the top of the third telescopic rod 23 is close to the energy metering terminal being tested. The telescopic component 2 is quick to operate, has a simple structure, and high reliability.

[0070] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
