Description

Technical Field

[0001] This invention relates to the field of energy meter de-functionalization technology, and more particularly to a device for de-functionalizing used energy meters. Background Technology

[0002] According to the regulations for the management of metering devices, electricity meters that are no longer operational must be forcibly scrapped. A large number of these meters need to be collected and thoroughly destroyed to prevent them from re-entering the market and causing chaos in the electricity market and electricity metering management. Due to the large number of electricity meters scrapped annually due to rotation or malfunctions, if manual drilling with a handheld electric drill is used, each scrapped meter needs to be drilled multiple times, requiring repeated disassembly and reassembly of the box – a repetitive and time-consuming process. Even with existing mechanically assisted scrapping methods, the meters still need to be removed from the box, placed on a production line for scrapping, and then returned to the box. During this process, broken particles are easily missed or dropped, making handling inconvenient and inefficient.

[0003] Chinese patent CN 117046859 A discloses a device for scrapping electricity meters, comprising: a detection and identification module for acquiring meter information of the meters to be scrapped and detecting whether the meters in the meter box are correctly placed; a scrapping module for scrapping the meters in the meter box, including a single-phase meter scrapping module composed of a single-phase scrapping unit and a single-phase limiting unit, and a three-phase meter scrapping module composed of a three-phase scrapping unit and a three-phase limiting unit; and a conveying module for sequentially conveying the meter box through the detection and identification module and the scrapping module. A method for scrapping electricity meters is also disclosed. This invention directly installs the meters in the meter box, acquires meter information through the detection and identification module and confirms correct placement, and then conveys them to the scrapping module for batch scrapping. This saves the process of disassembling and reassembling the meter box to retrieve and return the meters, and can destroy multiple meters at once, improving scrapping efficiency and facilitating transportation.

[0004] While existing technology can destroy multiple electricity meters at once, in actual use, the meters still need to be manually moved to the disposal device due to the height of the device itself, which is quite inconvenient.

[0005] Existing technology, such as Chinese utility model publication CN209754086U, discloses a multifunctional drilling device for scrapped energy meters, including a frame, a control box, a slide rail, an emergency stop button, a transmission wheel, a fixed plate, and a power mechanism. The fixed plate has a drilling mechanism and a slide rod, the slide rail has a base plate, and the base plate has a lifting mechanism. The power mechanism includes a motor and a chain, the chain being connected to a chain fixing seat at the bottom of the base plate. The drilling mechanism includes a drill bit holder and a drill bit, the upper part of which is fixed to the slide rod and the fixed plate. The lifting mechanism includes a top plate, the bottom of which has a hydraulic lifter and a limit rod, and the upper part of which has a fixing component and a turnover box. This addresses the problem of the lack of a low-cost, easy-to-operate, safe, and efficient multifunctional drilling device for scrapped energy meters of different sizes. However, manual movement of the meter to the drilling device is still required. Summary of the Invention

A pull strap is wound around the outer side of the rotating drum. A lifting block is provided at the other end of the pull strap. The lifting block is adapted to the edge of the transfer box.

[0009] A method for using a device to de-functionalize used electricity meters includes the following steps:

[0010] Step 1: Place the transfer box containing the used electricity meter under the lifting block;

[0011] Step 2: The first rotary motor rotates the drum to lower the lifting block, which then holds the two sides of the transfer box in place.

[0012] Step 3: The lifting block lifts the transfer box containing the waste electricity meter by winding the belt through the first rotating motor;

[0013] Step 4: Control the movement of the slider on the guide rod by using the slider drive component to move the transfer box below the defunctionalized component.

The drive end of the second rotary motor is connected to the gear. The flexible rack is disposed inside the slide rail. The flexible rack and the guide rod are both adapted to the interior of the slide rail. The slider is installed on the inner side of the flexible rack.

Furthermore, by designing multiple sliders, multiple transfer boxes can be successively lifted below the defunctionalization component, achieving a continuous scrapping process for used electricity meters. Compared to existing technologies, this device allows for both feeding and discharging without manual handling, making it more labor-saving and efficient. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figure 1 and Figure 2The waste electricity meter de-functionalization device includes a cabinet 1. A lifting drive device 2 is installed on the upper part of the cabinet 1. A de-functionalization component 3 is installed on the drive end of the lifting device. The device also includes a transfer box 4. The front of the transfer box 4 is T-shaped. A discharge port 7 is opened on the lower rear side of the cabinet 1. Slide rails 6 are installed on both sides of the discharge port 7. The bottom of the slide rails 6 is open. A guide rod 9 is provided inside the slide rails 6. A slider 10 is slidably arranged on the outer side of the guide rod 9. A slider 10 drive component is provided inside the slide rails 6. A first rotary motor 11 is installed at the bottom of the slider 10. A rotating drum 12 is installed on the drive end of the first rotary motor 11. A pull strap 13 is wound around the outer side of the rotating drum 12. A lifting block 14 is provided at the other end of the pull strap 13. The lifting block 14 is adapted to the edge of the transfer box 4.

[0031] In use, the transfer box 4 containing the waste electricity meters is first placed below the lifting block 14. Then, the first rotary motor 11 rotates the drum 12 to lower the lifting block 14, which then holds the two sides of the transfer box 4 in place. The first rotary motor 11 then winds the pull belt 13 to lift the transfer box 4 containing the waste electricity meters. This allows the transfer box 4 to be lifted instead of manually when de-functionalizing the waste electricity meters. The slider 10 is then moved on the guide rod 9 by the slider 10 drive component, moving the transfer box 4 below the de-functionalization component 3. Compared to existing technologies, this device allows for both feeding and discharging without manual handling, making it more labor-saving and efficient.

[0032] Example 2

[0033] Reference Figures 1-4 The difference between this embodiment and Embodiment 1 is that:

[0034] In this embodiment, the slide rail 6 driving assembly includes a flexible rack 15, a second rotary motor 16, and a gear 17. The top of the slide rail 6 is elliptical. The driving end of the second rotary motor 16 is connected to the gear 17. The flexible rack 15 is disposed inside the slide rail 6. The flexible rack 15 and the guide rod 9 are both adapted to the interior of the slide rail 6. The slider 10 is installed inside the flexible rack 15. The second rotary motor 16 can rotate the gear 17, driving the flexible rack 15 and the slider 10 to move inside the slide rail 6, thereby realizing the movement of the slider 10.

[0035] Moreover, compared to Embodiment 1, in specific implementation, the slide rail 6 in this embodiment is set in an elliptical shape to facilitate the cyclic movement of the slide rail 6. Multiple sets of sliders 10 can be designed so that multiple transfer boxes 4 can be lifted sequentially to the bottom of the defunctionalized component 3, realizing the continuous scrapping process of waste electricity meters.

[0036] In this embodiment, a brush structure 18 is provided on the inner side of the flexible rack 15, and a sliding contact line structure 19 is provided on the inner sidewall of the slide rail 6. The sliding contact line structure 19 is electrically connected to an external cable 20. The brush structure 18 abuts against the sliding contact line structure 19, and the brush structure 18 is electrically connected to the first rotary motor 11. Since the slider 10 of this device moves in one direction within the slide rail 6, by adopting the above structure, the slider 10 can be powered without a cable. The external cable 20 supplies power to the sliding contact line structure 19, and the sliding contact line mechanism supplies power to the first rotary motor 11 through the brush mechanism. This allows the first rotary motor 11 to be powered without connecting to the external cable 20, making the structure of this device more streamlined.

[0037] In this embodiment, a cable mounting post 21 is provided on the inner circumference of the slide rail 6, and the external cable 20 is mounted on the cable mounting post 21, which facilitates the installation of the cable mounting post 21 on the inner circumference of the slide rail 6.

[0038] In this embodiment, the second rotary motor 16 is mounted on the cable mounting post 21 by a bracket. The slide rail 6 has a through-hole 22 on its outer side. The gear 17 meshes with the flexible rack 15 through the through-hole 22. The second rotary motor 16 rotates the gear 17, so that the gear 17 drives the flexible rack 15 through the through-hole 22.

[0039] In this embodiment, the defunctionalized component 3 includes a third rotary motor, a drill rod installed on the drive end of the third rotary motor, and an electric moving platform that controls the movement of the third rotary motor. The electric moving platform is connected to the drive end of the lifting device. The electric moving platform can control the movement of the third rotary motor. The third rotary motor rotates the drill rod to destroy the waste electricity meter (in another embodiment, a multi-axis device can also be used to rotate multiple drill rods).

[0040] In this embodiment, a guide limiting block 23 is installed at the bottom opening of the slide rail 6. A positioning groove 8 is provided at the bottom of the guide limiting block 23. Guide grooves 24 are provided on both sides of the bottom of the positioning groove 8. The guide grooves 24 extend outward in the horizontal direction, so that when the top of the lifting block 14 moves to the guide groove 24, it can enter the positioning groove 8 along the guide groove 24 to be fixed, thus ensuring the stability of the transfer box 4 when the energy meter is damaged.

[0041] In this embodiment, a conveying device 25 is also included. The conveying device 25 is set at the bottom of the two slide rails 6, which facilitates the sequential conveying of multiple transfer boxes 4 through the conveying device 25 to realize the continuous feeding of transfer boxes 4. The conveying device 25 is embedded in the ground, which avoids the need for workers to lift the transfer boxes 4 onto the conveying device, thereby reducing the labor intensity of the workers.

[0042] In this embodiment, the cabinet 1 has a cabinet door on the front and an RFID reader on the inside of the cabinet door. The reader can read the asset code via RFID radio frequency and display the number of scrapped energy meters, the asset code, and the scrapping time on the software.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
