Description

Technical Field

[0001] This utility model relates to the field of single-phase electricity meter technology, and in particular to a quick-installation single-phase smart electricity meter. Background Technology

[0002] A single-phase smart meter is an advanced electronic meter that uses integrated circuits, modern communication and sensing technologies to measure, record and analyze the energy consumption of single-phase AC power (usually residential electricity). Single-phase meters are typically installed in centralized meter boxes, connected to the main switch and a residual current device (RCD). Multiple meter boxes in a region are usually concentrated in a single distribution room. When power workers are reading meters and performing maintenance, the operating space inside the meter box is small, and the meter is close to the main switch and the RCD, resulting in a limited field of vision, which is not conducive to meter reading and maintenance by power workers. Utility Model Content

[0003] The purpose of this invention is to solve the problem of limited operating space and field of vision for power workers when reading and repairing electricity meters in the prior art, and to propose a method for quickly installing single-phase smart meters.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick-installation single-phase smart meter includes a meter body, the lower end of which is provided with a wiring port for inserting a power cord, and telescopic mechanisms on both sides of the meter body.

[0006] The telescopic mechanism includes a sliding rod and a fixed rod symmetrically connected on both sides of the meter body. The sliding rod is slidably connected within the fixed rod, and a locking device is provided between the sliding rod and the fixed rod. One end of each fixed rod is provided with a fixing plate.

[0007] Preferably, the lower end of the fixing plate is provided with a conical block, and the surface of the conical block is provided with multiple wire harness grooves.

[0011] Preferably, the surface of the connecting rod is provided with an inclined groove, and one end of the locking rod is provided with a locking tooth that slides on the surface of the connecting rod.

[0012] Preferably, the inner side of the fixing rod is provided with an arc-shaped block, and the side of the clamping rod is provided with a guide block that is slidably connected to the arc-shaped block.

[0013] Compared with the prior art, this utility model provides a quick-installation single-phase smart meter with the following advantages:

[0014] 1. This quick-installation single-phase smart meter allows the sliding rod to slide linearly within the fixed rod by pulling the meter body, thereby increasing the operable space and field of vision of the meter body within the meter box. Furthermore, the squeezing column at one end of the connecting rod slides into contact with the continuous slot and restricts the movement of the sliding rod, increasing the stability of the meter body during maintenance and improving the efficiency of workers in maintaining the meter body in daily work.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0024] Reference Figure 1-4 A quick-installation single-phase smart meter includes a meter body 1, which is centrally installed in a distribution box. The lower end of the meter body 1 has four wiring ports 2, which are respectively connected to the main switch and the leakage current protection device. The lower end of the meter body 1 also has a wiring port 2 for plugging in the power cord. The meter body 1 has telescopic mechanisms 3 on both sides. When power workers are reading meters and performing maintenance on the meter body 1 in the distribution box, they can pull the meter body 1 to the outside, increasing the operating space of the meter body 1 and improving the daily work efficiency of power workers.

[0025] The telescopic mechanism 3 includes a sliding rod 301 and a fixed rod 302 symmetrically connected to both sides of the meter body 1. The sliding rod 301 slides within the fixed rod 302. Initially, the sliding rod 301 is completely within the fixed rod 302, allowing the meter body 1 to be as close as possible to the inside of the meter box, saving space in the meter box. The sliding rod 301 slides linearly within the fixed rod 302, thereby moving the meter body 1 outward, improving the operating space and field of vision for power workers. A locking element 4 is provided between the sliding rod 301 and the fixed rod 302 to maintain the stability of the sliding rod 301 within the fixed rod 302, preventing the meter body 1 from moving during maintenance. One end of each fixed rod 302 is provided with a fixing plate 303. The surface of the fixing plate 303 has multiple threaded holes for bolting into the meter box, keeping the meter body 1 within the meter box. For stability, the lower end of the fixing plate 303 is provided with a conical block 304, and the surface of the conical block 304 is provided with multiple wire harness grooves 305. The wires of the main switch and the residual current device can pass through the wire harness grooves 305 and connect to the wiring port 2 at the lower end of the meter body 1. This is beneficial to maintaining the orderliness of the wiring during installation. Moreover, the wires passing through the wire harness grooves 305 can increase the length of the spare wire. When the meter body 1 is moved to the outside, the spare wire is long enough to support the connection between the meter body 1 and the main switch and the residual current device. The fixing plate 303 has a multi-hole hollow structure, and a heat dissipation part 306 is provided between the fixing plate 303 and the meter body 1. When the meter body 1 is stationary in the distribution box, one side of the meter body 1 is in close contact with the fixing plate 303. At this time, there is a heat dissipation space between the meter body 1 and the inside of the distribution box, which is used to quickly dissipate the heat generated by the meter body 1 and improve the stability of the meter body 1 when operating at high power.

[0026] The locking component 4 includes a continuous groove 401 inside the fixed rod 302. The groove 401 is a right-angled groove. The pressing post 405 on one side of the slide rod 301 can slide across the inclined surface of the continuous groove 401 and continuously and repeatedly compress the torsion spring 404, so that the slide rod 301 can smoothly drive the meter body 1 to move outward. This is beneficial for moving the meter body 1 from the position near the inner wall of the meter box to the outside of the meter box, increasing the operating space and field of vision of the power workers. When the power workers begin to perform maintenance work on the meter body 1, the pressing post 405 on one side of the slide rod 301 makes direct contact with the groove 401, preventing the slide rod 301 from making a return movement inside the fixed rod 302, increasing the safety of the meter body. To ensure the stability of the meter body 1, one end of the slot 401 is connected to a return groove 406. The return groove 406 is rectangular, and its height is greater than that of the slot 401. This ensures that the pressing column 405 remains above the slot 401 and does not contact it. At this time, the slide rod 301 can drive the meter body 1 to make a return motion within the meter box, facilitating the return of the repaired meter body 1 to its original position by power workers. A connecting rod 402 and a locking rod 403 are rotatably connected to the surface of the slide rod 301. The connecting rod 402 is rectangular, with one end rotating within the slide rod 301 and, under the action of the torsion spring 404, ensuring the other end remains in contact with the slot 401. One end of the locking rod 403 rotates within the slide rod 301. Furthermore, under the action of the torsion spring 404, the locking tooth 408 at its other end always slides against the surface of the connecting rod 402. When the pressing post 405 at one end of the connecting rod 402 slides on the surface of the slot 401, the other end of the connecting rod 402 reciprocates around the torsion spring 404 at a specific angle. When the pressing post 405 moves to the return slot 406, the rotation angle of the connecting rod 402 increases, so that the locking tooth 408 successfully engages with the inclined slot 407. At this time, the electrician can push the meter body 1 back into the meter box. The connecting rod 402 and the locking rod 403 are respectively provided with torsion springs 404 between them and the slide rod 301, and one end of the connecting rod 402 is provided with a pressing post 405. The pressing post 405 is slidably connected to the slot 401. The surface of the rod 402 is provided with a slanted groove 407. One end of the locking rod 403 is provided with a locking tooth 408 that slides on the surface of the connecting rod 402. The inner side of the fixed rod 302 is provided with an arc-shaped block 409, and the side of the locking rod 403 is provided with a guide block 410 that slides and connects with the arc-shaped block 409. When the sliding rod 301 drives the meter body 1 back to its original position, the guide block 410 on one side of the connecting rod 402 slides and presses against the arc-shaped block 409 on the inner side of the fixed rod 302, causing the locking tooth 408 at one end of the locking rod 403 to separate from the slanted groove 407 at one end of the connecting rod 402. Under the action of the torsion spring 404, the pressing column 405 contacts the continuous locking groove 401 again, making it easy to return the meter body 1 to its initial state.

[0027] In this invention, the fixing plate 303 is fixed inside the meter box using bolts. When reading and repairing the meter body 1, the meter body 1 is pulled outwards from the meter box. At this time, the sliding rods 301 on both sides of the meter body 1 move within the fixing rod 302, and the pressing column 405 at one end of the connecting rod 402 on one side of the sliding rod 301 moves within the continuous slot 401. The pressing column 405 can stop at any time on the straight edge of the slot 401 surface, which facilitates the movement of the meter body 1 outwards from the meter box, allowing for easy movement and stopping. This increases the operating space and field of vision for power workers, making it easier for them to read and repair the meter body 1 during daily work. After the repair is completed, the meter body 1 is pulled outwards again, causing the pressing column 405 on one side of the sliding rod 301 to move onto the return groove 406. The locking teeth 408 at one end of the locking rod 403 engage with the inclined groove 407 on the surface of the connecting rod 402, keeping the pressing column 405 at one end of the connecting rod 402 separated from the locking groove 401. At this time, the worker can push the meter body 1 back to push the slide rod 301 back to the initial position of the fixed rod 302. Finally, the guide block 410 at one end of the locking rod 403 slides into contact with the arc block 409, separating the locking teeth 408 at one end of the locking rod 403 from the inclined groove 407, so that the pressing column 405 at one end of the connecting rod 402 contacts the continuous locking groove 401 again, thereby resetting the meter body 1 and improving the work efficiency of power workers in inspecting the meter body 1. In addition, the hollow multi-hole structure inside the fixed plate 303 and the heat dissipation part 306 between the meter body 1 and the meter box improve the heat dissipation efficiency of the meter body 1, which is beneficial to the stability of the meter body 1 when operating at high power.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
