Description

Technical Field

[0001] The invention relates to the technical field of electric energy meters, and in particular to a novel safety electric energy meter. Background Art

[0002] An electric energy meter is an instrument used to measure electric energy. It is also called an watt-hour meter, a fire meter, or a kilowatt-hour meter. It refers to an instrument that measures various electrical quantities. An electric energy meter is a product of the combination of sampling technology, microprocessing technology, design technology, and experience. It is an interdisciplinary high-tech product. Electric energy meter manufacturers realize the various functions of electric energy meters based on their own design understanding and application skills.

[0003] The Chinese invention patent with publication number CN116047133B discloses a new type of safe electric energy meter. The device drives the protective plate to move through the pressure when the box body is hit by the outside. The pressure of the fixed rod causes the external thread of the unloading rod to be threadedly engaged with the internal thread of the unloading sleeve to achieve the pressure unloading effect. During the rotation of the unloading rod, the unloading groove on its outside will continuously contact the unloading convex part. The resistance provided by the unloading convex part is used to achieve the purpose of unloading the unloading rod, thereby having a buffering effect on the protective plate and the box body, effectively buffering and protecting the collision force when the box body collides in time, solving the problem that the electric energy meter is difficult to protect itself when it is accidentally hit by the outside, further reducing the damage to the electric energy meter box body, and improving the safety performance of the device.

[0004] However, in actual use of the above scheme, the protective plate is arranged on the inner side of the electric energy meter. The pressure generated by the external collision must first be transmitted through the electric energy meter body before the protective plate can push the unloading rod to rotate to unload the force. In this scheme, the unloading rod has a slow impact response, and the internal components of the electric energy meter are more easily damaged during the collision, resulting in limited safety performance of the electric energy meter.

[0061] Embodiment 1: Figure 1-Figure 3 As shown, the present application discloses a novel safety electric energy meter, comprising an electric energy meter body 100, an electric energy meter housing 200 wrapped around the outer side of the electric energy meter body 100, a fixing seat 300 for installation, a power assembly and a control unit;

[0062] The electric energy meter housing 200 is used to protect the electric energy meter body 100, and the electric energy meter housing 200 includes a bottom shell 210 disposed on the bottom side thereof;

[0063] The bottom shell 210 is used to be installed with the fixing seat 300. The bottom shell 210 is rectangular and includes a load-releasing ring 211 and a deformation joint 212.

[0064] The unloading ring 211 is disposed at the center of the bottom shell 210, and the unloading ring 211 is in a circular shape, and a thread is disposed on the inner side of the unloading ring 211;

[0065] The deformation joint 212 is provided at the center of the bottom shell 210. The deformation joint 212 is in a cross shape. The deformation joint 212 divides the bottom shell 210 and the unloading ring 211 into four parts along the four sides of the deformation joint 212. The deformation joint 212 is used to provide deformation space for the four parts of the bottom shell 210.

[0066] The fixing seat 300 includes a mounting base plate 310, a mounting side plate 320 and a force unloading sleeve 330;

[0067] The installation base plate 310 is rectangular, and its length and width are larger than the electric energy meter housing 200;

[0068] The mounting side plate 320 is fixedly connected to the center of the mounting bottom plate 310. The mounting side plate 320 is annular. The internal shape and size of the mounting side plate 320 are the same as those of the electric energy meter housing 200. The mounting side plate 320 is used to mount the electric energy meter housing 200.

[0069] The unloading sleeve 330 is arranged at the center of the mounting side plate 320, and the unloading sleeve 330 is rotatably connected with the mounting bottom plate 310. The unloading sleeve 330 is in a circular shape, and the outer diameter of the unloading sleeve 330 is smaller than the inner diameter of the unloading ring 211. The unloading sleeve 330 includes a spiral sheet 331 and a unloading protrusion 332.

[0070] The spiral piece 331 is arranged outside the unloading sleeve 330, the pitch of the spiral piece 331 is the same as the pitch of the inner thread of the unloading ring 211, and the outer diameter of the spiral piece 331 is the same as the inner diameter of the inner thread of the unloading ring 211;

[0071] The unloading protrusions 332 are fixedly connected to the outside of the unloading sleeve 330 . The unloading protrusions 332 are evenly distributed in the gaps of the spiral pieces 331 . The unloading protrusions 332 are made of rubber. The length of the unloading protrusions 332 is smaller than the blade width of the spiral pieces 331 .

[0072] The mounting base plate 310 further includes support blocks 311, which are disposed at the four inner corners of the mounting side plate 320. The support blocks 311 are fixedly connected to the mounting base plate 310. The support blocks 311 are made of rubber and are used to support the electric energy meter housing 200 and allow a certain degree of deformation.

[0073] Working principle: When the electric energy meter encounters an external collision, the electric energy meter housing 200 is hit first. After the electric energy meter housing 200 is hit, the impact side of the electric energy meter housing 200 is deformed, thereby driving the corresponding unloading ring 211 to move closer to the center. After the unloading ring 211 moves, the inner thread of the unloading ring 211 is screwed with the spiral sheet 331, and at the same time, the inner thread of the unloading ring 211 contacts the unloading convex part 332. At the same time, the electric energy meter housing 200 will be pressed down when it is hit, and the support block 311 allows the electric energy meter housing 200 to move down slightly, thereby driving the unloading ring 211 to move down, so that the unloading ring 211 pushes the unloading sleeve 330 to rotate. When the unloading sleeve 330 rotates, the unloading is carried out by the friction between the unloading convex part 332 and the unloading ring 211.

[0074] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0075] The impact is directly transmitted to the unloading ring 211 and the unloading sleeve 330 through the electric energy meter housing 200. The unloading ring 211 and the unloading sleeve 330 are in contact and screwed together, making the impact response faster and effectively reducing the impact on internal components. Through a more effective buffering and unloading mechanism, the overall safety performance of the electric energy meter is improved.

[0076] Embodiment 2: The energy meter housing 200 in the above embodiment usually collides at the four edges of the front side, and the displacement generated when the top end of the energy meter housing 200 collides is often excessively attenuated when it is transmitted to the unloading ring 211 through the energy meter housing 200, affecting the unloading effect of the unloading ring 211 and the unloading sleeve 330; the embodiment of the present application is optimized to a certain extent on the basis of the above embodiment.

[0077] like Figure 4-Figure 5 As shown, the mounting side plate 320 is provided with a first through hole 321 , and the first through hole 321 is located at the center of the bottom side of the four sides of the mounting side plate 320 .

[0078] Furthermore, the fixing seat 300 further includes an auxiliary buffer assembly 340, and the auxiliary buffer assembly 340 is used to protect the electric energy meter housing 200, and the auxiliary buffer assembly 340 includes a U-shaped rod 341, an auxiliary baffle 342 and a friction member 343;

[0079] The lengths of the two sides of the U-shaped rod 341 are different. The bending vertex of the U-shaped rod 341 passes through the first through hole 321. The U-shaped rod 341 is rotatably connected to the mounting side plate 320. The longer side of the U-shaped rod 341 is arranged on the outer side of the mounting side plate 320, and the shorter side of the U-shaped rod 341 is arranged on the inner side of the mounting side plate 320.

[0080] The auxiliary baffle 342 is arranged outside the four edges of the front side of the electric energy meter housing 200, and the middle part of the auxiliary baffle 342 is fixedly connected to the top of the long section of the U-shaped rod 341, and the auxiliary baffle 342 is used to protect the edges of the electric energy meter housing 200;

[0081] The friction member 343 is disposed at the top end of the shorter section of the U-shaped rod 341 . The friction member 343 is in contact with the unloading ring 211 . The friction member 343 has a rough surface to increase friction.

[0082] Working principle: When a collision occurs, the auxiliary baffle 342 is hit first, and the auxiliary baffle 342 drives the U-shaped rod 341 to rotate after the collision. The U-shaped rod 341 drives the friction member 343 to rotate. The friction member 343 squeezes the unloading ring 211 inward and gives the unloading ring 211 a downward friction force, thereby enhancing the friction between the unloading ring 211 and the unloading protrusion 332, and at the same time makes the unloading ring 211 contact and screw with the spiral sheet 331, so as to unload the force faster.

[0083] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0084] Through the cooperation of the auxiliary baffle 342 and the U-shaped rod 341, the displacement generated during the collision is directly transmitted to the unloading ring 211, so that the unloading ring 211 can be screwed with the unloading sleeve 330 more quickly, thereby improving the response speed and increasing the friction between the unloading ring 211 and the unloading sleeve 330, thereby further improving the unloading effect. In addition, the first contact point during the collision is no longer located on the electric energy meter housing 200, thereby further reducing the impact on the internal components. Through a more effective buffering and unloading mechanism, the overall safety performance of the electric energy meter is improved.

[0085] Embodiment 3: Although the auxiliary baffle 342 in the above embodiment blocks the electric energy meter housing 200 from direct collision when a collision occurs, the auxiliary baffle 342 may still collide with the electric energy meter housing 200 after being impacted, and still transmit the impact to the inside; the embodiment of the present application is optimized based on the above embodiment.

[0086] like Figure 6-Figure 7As shown, the fixing seat 300 further includes a linkage auxiliary buffer type protection component 350, which is disposed between the auxiliary baffle 342 and the electric energy meter housing 200, and is used to accelerate the absorption of impact energy, and the linkage auxiliary buffer type protection component 350 includes a support rod 351, an elastic component 352 and a connecting rod 353;

[0087] The bottom of the support rod 351 is fixedly connected to the mounting base plate 310. The support rod 351 is arranged outside the four corners of the mounting base plate 310. The support rod 351 is used to support the linkage auxiliary buffer type protection component 350.

[0088] The elastic component 352 is annular, and is disposed between the auxiliary baffle 342 and the electric energy meter housing 200. The four corners of the elastic component 352 are fixedly connected to the support rod 351. The elastic component 352 is made of elastic material, and the elastic component 352 is vertically deformed after being horizontally squeezed.

[0089] The connecting rod 353 is fixedly connected to the lower side of the middle section of the elastic component 352 , and the bottom end of the connecting rod 353 is fixedly connected to the unloading ring 211 .

[0090] Furthermore, the mounting side plate 320 further includes a sliding groove 322 , and the sliding groove 322 is slidably connected to the connecting rod 353 .

[0091] Working principle: When a collision occurs, the auxiliary baffle 342 is impacted and then hits the elastic component 352. The elastic component 352 prevents the electric energy meter housing 200 from being directly hit, thereby achieving a buffering effect. At the same time, the two sides of the elastic component 352 are squeezed by the electric energy meter housing 200 and the auxiliary baffle 342, and the elastic component 352 is vertically deformed. The elastic component 352 is squeezed downward, and the elastic component 352 pushes the connecting rod 353. The connecting rod 353 slides downward along the sliding groove 322, and the other end of the connecting rod 353 drives the unloading ring 211 to move downward, thereby increasing the rotation amplitude of the unloading sleeve 330 and improving the unloading effect.

[0092] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0093] The auxiliary baffle 342 and the elastic component 352 can more effectively absorb the impact energy and reduce the risk of damage to internal components. The elastic component 352 is squeezed and deformed to drive the unloading ring 211 to move downward, so that the unloading mechanism can be started faster and the unloading effect is better. Through a more effective buffering and unloading mechanism, the overall safety performance of the electric energy meter is improved.

[0094] Embodiment 4: The elasticity of the elastic component 352 in the above embodiment is constant, and it is not convenient to adjust the elasticity to achieve the best protection effect when facing collisions under different conditions; the embodiment of the present application is optimized to a certain extent on the basis of the above embodiment.

[0095] like Figure 8-Figure 10 As shown, the elastic component 352 is hollow inside, the elastic component 352 forms an air bag, and the elastic component 352 further includes an air injection port 3521 and a pressure sensor 3522;

[0096] The gas injection port 3521 is disposed at the lower side of the elastic component 352, and the gas injection port 3521 is used to control the injection and discharge of gas in the elastic component 352;

[0097] The pressure sensor 3522 is disposed between the elastic component 352 and the auxiliary baffle 342 . The pressure sensor 3522 is fixedly connected to the elastic component 352 .

[0098] Furthermore, the linkage auxiliary buffer-type protection component 350 also includes a micropump 354, which is fixedly connected to the mounting side plate 320, and is connected to the gas injection port 3521 through an air duct, and is connected to the pressure sensor 3522 through a wire, and is used to control the amount of gas injected or extracted into the elastic component 352 through the gas injection port 3521 according to the signal of the pressure sensor 3522.

[0099] The fixing base 300 also includes a power component, which is used to provide energy for the operation of the micro pump 354, preferably an AC power supply or a battery; the micro pump 354 includes a control unit, preferably a programmable logic controller; both are prior arts and will not be described in detail here.

[0100] Working principle: A certain amount of gas is maintained in the elastic component 352 to maintain a certain initial shape and elasticity. The pressure sensor 3522 continuously monitors the external environment. When the auxiliary baffle 342 hits the elastic component 352, the pressure sensor 3522 detects the pressure change and transmits the signal to the micro pump 354. The micro pump 354 automatically injects or discharges an appropriate amount of gas into the elastic component 352 through the gas injection port 3521 according to the received pressure signal, and adjusts its shape and elasticity. As the shape and elasticity of the elastic component 352 change, its response to external force impact is more flexible, and it can better absorb and disperse the impact energy. At the same time, the adjusted elastic component 352 transmits the force to the unloading ring 211 through the connecting rod 353, accelerates the screwing process between it and the unloading sleeve 330, and realizes efficient unloading. After the impact, the micro pump 354 adjusts the amount of gas in the elastic component 352 in real time according to the signal of the pressure sensor 3522, so that it returns to the optimal state and prepares for the next impact protection.

[0101] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0102] Through air injection, the elastic component 352 can automatically adjust its shape and elasticity according to the impact force to provide a more precise cushioning effect. The adaptive adjustment enables the device to maintain a high level of protection under various impact conditions and reduces the risk of damage to internal components. By precisely controlling the shape and elasticity of the elastic component 352, the service life of the device is extended and damage caused by long-term uneven force is reduced. Although the adjustment steps are increased, the entire adjustment process is completed automatically without manual intervention, thereby simplifying daily operation and maintenance procedures. Higher protection performance and longer service life directly improve the user experience and satisfaction.

[0103] Embodiment 5: When the elastic component 352 in the above embodiment is squeezed by the auxiliary baffle 342, the vertical displacement transmitted to the connecting rod 353 by the elastic component 352 is small, resulting in limited unloading effect of the unloading ring 211; the embodiment of the present application is optimized to a certain extent on the basis of the above embodiment.

[0104] like Figure 11-Figure 12 As shown, the elastic component 352 further includes a lower extrusion film 3523 and an upper extrusion film 3524;

[0105] The lower extrusion film 3523 is provided at the connection between the elastic component 352 and the connecting rod 353. The lower extrusion film 3523 is in the shape of a thin film and is made of rubber. When the elastic component 352 is squeezed and deformed by the auxiliary baffle 342, the internal air of the lower extrusion film 3523 squeezes it downward. The lower extrusion film 3523 is used to drive the connecting rod 353 to move.

[0106] The upper extrusion film 3524 is disposed at both ends of the upper side of the elastic component 352 . The upper extrusion film 3524 is in the shape of a thin film and is made of rubber. The upper extrusion film 3524 is used to extrude upward to push the auxiliary baffle 342 to reset.

[0107] Working principle: After the auxiliary baffle 342 is collided, it squeezes the elastic component 352. After the elastic component 352 is squeezed and deformed, the internal volume becomes smaller, and the gas is squeezed downward through the lower extrusion membrane 3523. The lower extrusion membrane 3523 pushes the connecting rod 353 to move downward, and the connecting rod 353 drives the unloading ring 211 to move downward, thereby promoting the screwing process of the unloading ring 211 and the unloading sleeve 330 to unload the force. At the same time, the pressure sensor 3522 located between the elastic component 352 and the auxiliary baffle 342 detects the pressure change and sends a signal to the micro pump 354. After the control unit of the micro pump 354 receives the signal and makes a judgment and processes it, the micro pump 354 inflates the elastic component 352 through the gas injection port 3521, thereby further increasing the downward extrusion distance of the lower extrusion membrane 3523, increasing Strong unloading effect. In addition, as the amount of gas inside the elastic component 352 increases, the upper extrusion film 3524 is also slightly squeezed upward to push the auxiliary baffle 342. When the collision impact on the auxiliary baffle 342 ends, the upper extrusion film 3524 pushes the auxiliary baffle 342 to reset. The pressure sensor 3522 detects the pressure change and sends a signal to the micro pump 354 again. After the control unit of the micro pump 354 receives the signal and makes a judgment and processes it, the micro pump 354 draws air from the elastic component 352 through the air injection port 3521 to restore the internal gas of the elastic component 352 to its initial amount. At the same time, the lower extrusion film 3523 and the upper extrusion film 3524 also return to their initial state. The unloading ring 211 is no longer screwed with the unloading sleeve 330, so that it returns to its optimal state and prepares for the next impact protection.

[0108] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0109] When the elastic component 352 is deformed by extrusion, the lower extrusion membrane 3523 partially moves downward, thereby increasing the vertical movement distance of the unloading ring 211 under the same degree of extrusion, thereby obtaining a better unloading effect. At the same time, through the detection of the pressure sensor 3522, the internal air volume of the elastic component 352 is adjusted in real time so that it can adapt to the impact and recover quickly, thereby obtaining a better protection effect and service life.

[0110] Embodiment 6: The unloading ring 211 in the above embodiment may not immediately cooperate with the unloading sleeve 330 to rotate and unload the force at the moment of impact, and the energy of the impact cannot be effectively converted on the electric energy meter body 100 at this time, which may cause damage to the electric energy meter body 100; the embodiment of the present application is optimized based on the above embodiment.

[0111] like Fig.13 As shown, the elastic component 352 also includes a shaking portion 3525, which is in the shape of a film and is arranged on the inner side of the middle of each side of the elastic component 352. The shaking portion 3525 is made of rubber. When the elastic component 352 is squeezed and deformed by the auxiliary baffle 342, the internal air squeezes the shaking portion 3525 inward. The shaking portion 3525 is used to respond to the local high pressure during squeezing and perform local extrusion, and reduce the degree of extrusion as the air pressure disperses, thereby shaking the electric energy meter body 100.

[0112] Working principle: At the moment of collision, the auxiliary baffle 342 is hit and falls toward the elastic component 352. When the auxiliary baffle 342 transmits the impact to one side of the elastic component 352, the elastic component 352 is partially compressed and the internal air pressure increases instantly, thereby squeezing out the corresponding shaking part 3525 inside and pushing the electric energy meter body 100. After a short period of time, due to the pressure generated by the elasticity of the shaking part 3525 itself on the internal gas and the fluidity and diffusion of the gas, the high-pressure gas will be transmitted to the surrounding along the annular structure of the elastic component 352, and gradually diffuse to other parts of the elastic component 352. As the air pressure at the initial point of the squeeze increases, the pressure at the initial point of the squeeze increases. As the air pressure increases, the extruded shaking portion 3525 shrinks under its own elastic force, and the shaking portions 3525 on the other sides are squeezed out, pushing the electric energy meter body 100 from different directions. The shaking portions 3525 on each side fluctuate back and forth, forming a dynamic support for the electric energy meter body 100, thereby causing the electric energy meter body 100 to shake. At this point, part of the energy of the impact is converted into the kinetic energy of the electric energy meter, which can disperse and mitigate the impact force, so that different parts of the electric energy meter body 100 share the momentum generated by the impact, thereby reducing the local impact on the electric energy meter body 100 and reducing the probability of damage to the electric energy meter body 100.

[0113] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0114] The alternating fluctuation of the shaking parts 3525 on each side under impact pushes the electric energy meter body 100 to shake, thereby converting part of the energy of the impact on the electric energy meter body 100 into the kinetic energy of the electric energy meter, which can disperse and mitigate the impact force, allowing different parts of the electric energy meter body 100 to share the momentum generated by the impact, thereby reducing the damage to the electric energy meter body 100.

[0115] Embodiment 7: The elastic component 352 in the above embodiment can only be adjusted as a whole, but in actual use, collisions at various angles and positions may occur; the embodiment of the present application is optimized to a certain extent on the basis of the above embodiment.

[0116] like Figure 14-15As shown, the interior of the elastic component 352 is divided into eight cavities, each cavity is provided with an air injection port 3521 and a pressure sensor 3522, the number of the micro pumps 354 is the same as the number of the cavities, the cavities and the micro pumps 354 constitute a plurality of groups of coordinated control type elastic unloading systems, the plurality of groups of coordinated control type elastic unloading systems have four elastic buffer groups A and four elastic buffer groups B, the elastic buffer group A is arranged along the two long sides of the electric energy meter housing 200, and the elastic buffer group B is arranged along the two short sides of the electric energy meter housing 200.

[0117] Furthermore, the mounting base plate 310 is fixedly connected to a central control unit 355, and the central control unit 355 is electrically connected to each pressure sensor 3522, and the central control unit 355 is electrically connected to each micro pump 354. The central control unit 355 is used to receive signals from all pressure sensors 3522 to comprehensively determine the direction and strength of the impact and issue instructions to each group of micro pumps 354.

[0118] Working principle: a preset amount of gas is maintained in all cavities, and each group of elastic bags is in standby mode. The central control unit 355 continuously monitors the signals of each group of pressure sensors 3522. When the box body is hit, each group of pressure sensors 3522 detects the pressure change and transmits the signal to the central control unit 355. The central control unit 355 comprehensively judges the direction and strength of the impact based on the received pressure signal. The central control unit 355 sends a gas injection instruction to each group of micro pumps 354 based on the judgment result. Each group of micro pumps 354 adjusts the amount of gas in its own cavity and changes its shape and elasticity according to the instruction of the central control unit 355. Each group works together to effectively absorb and disperse the impact energy, and transmits the force to the unloading ring 211 through the connecting rod 353 to achieve buffering and unloading. After the impact, the central control unit 355 adjusts the elastic component 352 to the optimal state according to the signal of the pressure sensor 3522 to prepare for the next impact protection.

[0119] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0120] Through the coordinated work of elastic buffer group A and elastic buffer group B, more comprehensive protection and more efficient energy absorption are achieved. By optimizing the algorithm of the central control unit 355, the accuracy of its judgment on the direction and force of the impact, as well as the accuracy and timeliness of the control instructions can be improved. At the same time, the coordination and response speed between the cavities in each group can be ensured to achieve more efficient and precise collaborative work.
