[0040] The beneficial effects that can be achieved by the above embodiments of the present invention include:

[0041] (1) The resisting plate contacts the meter, clamping and fixing the meter used in the meter box to prevent the meter from shaking or dislodging due to instability during use. At the same time, when the two resisting plates contact the two sides of the meter, the buffer pads on the resisting plates also contact the meter, increasing the friction between the resisting plates and the meter, further improving the fixing effect of the meter. If the meter shakes due to external factors such as impact during use, the buffering force brought by the buffer pads and the resisting spring can absorb the impact force, so that the impact force on the meter is transferred to the attached buffer pads, causing the resisting plate on it to move at the upper limit of the resisting plate through the buffer cylinder. When the spring is moved, it deforms, which deflects the impact force acting on the meter to achieve the effects of energy absorption and buffering. This prevents the meter from becoming unstable or damaged due to impact, and improves its service life and stability. It also prevents the meter from being damaged or knocked off by strong impacts during use, allowing it to adapt to different usage environments and ensuring its stability. This prevents the multi-functional meter from shaking due to external factors such as impacts, improves its working accuracy and extends its lifespan, thereby further reducing the limitations of the multi-functional meter in use.

[0042] (2) The active shaft rotates rapidly back and forth on the filter plate, causing the fan blades on the active shaft to rotate rapidly back and forth in the ventilation holes. When the fan blades rotate rapidly in one direction, they are used to dissipate the heat generated by the meter in the meter box during use. When the fan blades rotate rapidly in the other direction, they are used to draw in the cooling gas from the outside into the meter box, so that the cooling gas acts on the area around the meter in the meter box to reduce the operating temperature of the meter. This prevents the meter from being affected by excessive temperature when it is used in the meter box, thereby improving the meter's performance and metering accuracy, and further extending the meter's service life. This also allows for a reduction in the meter's operating temperature when maintaining or replacing the drive motor. At the same time, when the active shaft rotates on the filter plate, the scraper on the active shaft rotates continuously on the surface of the filter plate to clean the impurities adhering to the filter plate. This prevents excessive impurities from adhering to the filter plate, which would affect the gas flow rate and reduce the heat dissipation effect, thereby improving the heat dissipation effect on the meter.

[0043] (3) When the displacement base moves, it synchronously drives the directional cylinder to move, so that it moves to a limited position at the directional shaft. At the same time, it keeps the telescopic base in a stretched state until the driven gear on the displacement base meshes with the driving gear. At this time, the driven gear is still meshed with the second large gear, so that the power source of the driving gear is switched. If the meter is subjected to an impact from external factors during use, the impact force will be fed back to the long plate on the stop buffer, so that the distance between it and the horizontal plate changes. This causes the L-shaped rack on the long plate to mesh with the stop gear on the horizontal plate when it moves, so that it drives the directional shaft to rotate through the stop shaft, which in turn drives the directional cylinder to rotate, so that the limiting ring on it is on the semi-ring seat. The limiting rotation within the annular groove causes the second large gear on the directional cylinder to rotate, which in turn meshes with the driven gear. This drives the meshing drive gear, which in turn rotates the fan blades. Under the action of the guide disc, guide block, and transmission belt on the rotating exhaust mechanism, the fan blades remain in a rotating state, thus reducing the operating temperature of the meter. In other words, it converts the kinetic energy of the meter under impact during use into a power source for cooling the meter, reducing the limitations of the meter's use and further improving its performance. When maintenance of the drive motor is required, operating the electric telescopic column reset setting will stop the stop damper from driving the fan blades and switch the power source acting on the fan blades to the locking unit.

[0044] (4) If the impact intensity of the meter during use is too great, it will further compress the distance between the long plate and the horizontal plate until the signal pieces on the opposite surfaces of the two contact. This means that the impact force on the meter is too strong, so the force fed back to the long plate is also strong enough, which causes the two signal pieces to contact and send a signal to the controller. The controller then sends the signal to the staff on duty to remind them to pay attention in time and avoid the meter from being affected by untimely maintenance, thereby further improving the meter's performance.

[0045] (5) The installation and removal of the drive motor are convenient and quick, and no tools are required during the process, which reduces the limitations of the meter's use. This makes it easier to maintain the drive motor and replace it with different models to adapt to different usage scenarios, thereby improving the meter's performance. It is worth mentioning that when the locking block is connected to the locking slot, if the drive motor is impacted and shakes during use, the impact force will be fed back to the locking block through the locking slot on the drive motor. This causes the retaining cylinder on it to move within the retaining cylinder to absorb energy and reduce force. At the same time, the retaining spring is in a buffer position. The locking mechanism is designed to absorb the impact force experienced by the drive motor during operation, thereby improving the stability of the drive motor. When the locking block and locking slot are connected, the installation of the drive motor is complete. At this point, by releasing the positioning plate that was originally pulled outward, the positioning spring is reset, which in turn moves the positioning plate on the positioning plate back to its original position. This allows the positioning plate to pass through the side of the locking slide and connect with one of the positioning square holes, thus limiting the locking slide. This prevents the drive motor from dislodging due to movement of the locking slide while the drive motor is being fixed in place, thereby improving the installation effect of the drive motor and further reducing its limitations in use.

[0065] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0066] Implementation examples, by Figures 1 to 16 The present invention includes a meter box 1, connected to a wall; a meter installed inside the meter box 1; a stop damper on the meter box 1 for absorbing energy generated when the meter is subjected to impact during use; the stop damper includes a stop screw 2, installed on the inner wall of the meter box 1; two stop screws 2 are symmetrically arranged on both sides of the meter; the end points of the stop screws 2 face the meter; a positioning frame 3 is installed on the outer wall of the meter box 1; a drive motor 4 is fitted into the positioning frame 3, and the two are slidably engaged; the output end of the drive motor 4 is rotatably connected to the stop screw 2; a locking unit is used to facilitate the replacement or maintenance of the drive motor 4; a rotating exhaust mechanism is used to reduce the operating temperature of the meter during use; a stop block 8 is threadedly connected to the stop screw 2; a stop cylinder 9 is installed on the inner wall of the meter box 1; the stop block 8 is connected through the stop cylinder 9 on the side near the meter; the stop cylinder 9 and the stop block 8 are slidably engaged; and a stop plate 1. 0, installed on the stop block 8; a buffer cylinder 11 is connected through the stop plate 10 near the meter; the buffer cylinder 11 and the stop plate 10 are in sliding fit; a buffer limit plate is installed at the end of the buffer cylinder 11 away from the meter; a stop spring 12 is sleeved on the stop cylinder 9; one end of the stop spring 12 is fixedly connected to the buffer limit plate, and the other end is fixedly connected to the stop plate 10; a stop elongated plate 13 is installed at the end of the buffer cylinder 11 near the meter; a buffer pad 14, connected to... A stop plate 13 is attached to the side of the meter; the side of the meter is located on the moving path of the buffer pad 14; a signal piece 15 is attached to the opposite sides of the stop plate 13 and the stop plate 10; an L-shaped rack 16 is attached to the stop plate 13; a stop base 17 is attached to the stop plate 10; a stop shaft 18 is attached to the stop base 17; a stop gear 19 is attached to the stop shaft 18; the stop gear 19 meshes with the L-shaped rack 16.

[0067] When the electricity meter is used inside the meter box 1, the drive motor 4 is started, causing its output end to drive the stop screw 2 to rotate. This causes the threaded stop block 8 to move at its upper limit on the stop cylinder 9, which in turn moves the stop plate 10 on the stop block 8 closer to the electricity meter. Under the action of the buffer cylinder 11 and the stop spring 12, the stop plate 10 moves the stop elongated plate 13 closer to the electricity meter, causing the two stop elongated plates 13 on both sides of the electricity meter to move relative to each other until the stop elongated plate 13 contacts the electricity meter. This clamps and fixes the electricity meter used inside the meter box 1, preventing the meter from shaking or dislodging due to instability during use. Simultaneously, when the two stop plates 13 contact the sides of the meter, the buffer pads 14 on the stop plates 13 also contact the meter, increasing the friction between the stop plates 13 and the meter and further improving the meter's fixation effect. If the meter shakes due to external factors such as impact during use, the buffering force provided by the buffer pads 14 and the stop springs 12 absorbs the impact force, transferring the impact force to the attached buffer pads 14. This causes the stop plates 13 to move at the upper limit of the stop plate 10 via the buffer cylinder 11, causing the stop springs 12 to deform. The mechanism absorbs and buffers the impact forces acting on the meter, preventing instability or damage caused by shocks. This extends the meter's lifespan and stability, preventing damage to internal precision parts from strong impacts. The meter can adapt to different operating environments, ensuring stable operation and preventing wobbling due to external factors like impacts. This improves the meter's accuracy and extends its lifespan, further reducing the risk of damage. Limitations of electricity meter usage; it is worth mentioning that if the impact intensity on the electricity meter during use is too great, it will further compress the distance between the resistance plate 13 and the resistance plate 10 until the signal pieces 15 on their opposite surfaces come into contact. This means that the impact force on the electricity meter is too strong, so the force fed back to the resistance plate 13 is also strong enough to cause the two signal pieces 15 to come into contact and send a signal to the controller. The controller then sends this signal to the on-duty personnel to remind them to pay attention in time and avoid untimely maintenance that may affect the use of the electricity meter, thereby further improving the use efficiency of the electricity meter.

[0068] The locking unit in this embodiment includes a locking slot 5, disposed on the side wall of the drive motor 4; a locking post 6, installed on the side of the meter box 1 near the wall; a locking limit plate connected to the end of the locking post 6 away from the meter box 1; a locking slide plate 20; the side of the locking slide plate 20 near the meter box 1 is connected through to the locking post 6; the locking post 6 and the locking slide plate 20 are in sliding engagement; a locking spring 21, sleeved on the locking post 6; one end of the locking spring 21 is fixedly connected to the locking limit plate, and the other end is fixedly connected to the locking slide plate 20; a positioning square hole 22; a plurality of positioning square holes 22 are arranged at equal intervals and are disposed through the side of the locking post 6; a positioning cylinder 23, installed on the side of the locking slide plate 20 away from the opening of the positioning square hole 22; a positioning horizontal plate 24 is connected through the positioning cylinder 23, and the two are in sliding engagement; the positioning horizontal plate 24 is close to the positioning square hole 22. A positioning plate 25 is installed on one side; after passing through the side of the locking slide plate 20, the positioning plate 25 is connected to one of the positioning square holes 22; a positioning spring 26 is fitted on the positioning cylinder 23; one end of the positioning spring 26 is fixedly connected to the positioning horizontal plate 24, and the other end is fixedly connected to the positioning limiting plate; the positioning limiting plate is connected to the end of the positioning cylinder 23 away from the locking slide plate 20; a retaining cylinder 27 is installed on the side of the locking slide plate 20 near the positioning frame 3; a retaining cylinder 28 is fitted inside the retaining cylinder 27, and the two slide in cooperation; a locking block 29 is installed on the end of the retaining cylinder 28 near the drive motor 4; after passing through the side of the positioning frame 3, the locking block 29 is connected to the locking groove 5; a retaining spring 30 is provided inside the retaining cylinder 27; one end of the retaining spring 30 is fixedly connected to the bottom surface inside the retaining cylinder 27, and the other end is fixedly connected to the retaining cylinder 28;

[0069] The power source used to protect the meter comes from the drive motor 4. By pulling the positioning plate 24 outward, it is limited to move at the positioning cylinder 23, so that the positioning spring 26 is in a buffer state. Then, the positioning insert 25 on the positioning plate 24 disengages from the locking slide plate 20 and is no longer connected to the positioning square hole 22. At this time, by pulling the locking slide plate 20 outward, the retaining cylinder 27 on it moves away from the drive motor 4. The locking spring 21 is in a buffer state, so that the retaining cylinder 27, under the action of the retaining cylinder 28 and the retaining spring 30, drives the locking block 29 away from the drive motor 4. This allows the locking block 29 to disengage from the positioning frame 3 and is no longer connected to the locking slot 5 on the drive motor 4. This releases the limiting setting on the drive motor 4. The drive motor 4 can then be pulled outwards to disengage it from the positioning frame 3, thus completing the disassembly operation. When installing a new or different model drive motor 4, insert it into the positioning frame 3, connecting the output end of the drive motor 4 to the stop screw 2. Releasing the force applied to the locking slide plate 20 resets the locking spring 21, causing the locking slide plate 20 to move back to its original position. This allows the locking block 29 on the slide plate to enter the side of the positioning frame 3 and connect with the locking groove 5 on the drive motor 4, thus limiting the drive motor 4 embedded in the positioning frame 3 and completing the disassembly operation. The installation and removal of the drive motor 4 are convenient and quick, and can be completed without any tools, reducing the limitations of the meter's use. This facilitates maintenance of the drive motor 4 and the replacement of different models to suit various usage scenarios, thereby improving the meter's performance. It is worth mentioning that when the locking block 29 is connected to the locking slot 5, if the drive motor 4 is impacted and shakes during use, the impact force will be fed back to the locking block 29 through the locking slot 5 on the drive motor 4. This causes the retaining cylinder 28 to move within the retaining cylinder 27, thus absorbing energy and dissipating force. Simultaneously, the retaining spring 30 is in a relaxed state. In the impact state, it is used to absorb the impact force received by the drive motor 4 during use, thereby improving the stability of the drive motor 4. When the locking block 29 and the locking slot 5 are connected, it means that the installation of the drive motor 4 is completed. At this time, by releasing the positioning horizontal plate 24 that was originally pulled outward, the positioning spring 26 is reset, which drives the positioning insert plate 25 on the positioning horizontal plate 24 to reset and move, so that it passes through the side of the locking slide plate 20 and connects with one of the positioning square holes 22, thereby limiting the locking slide plate 20. This prevents the drive motor 4 from being dislodged due to the movement of the locking slide plate 20 while limiting and fixing the drive motor 4, thereby improving the installation effect of the drive motor 4 and further reducing its usage limitations.

On shaft 33; the end of spring 36 is connected to meter box 1; guide base 37 is installed on the side of meter box 1 near the wall; guide turntable 38 is installed on the side of guide base 37 near meter box 1; guide column 39 is connected to the edge of guide turntable 38 near meter box 1; active base 40 is installed on guide base 37; active base 40 has a through guide slide column 41 on the side of guide column 39; guide slide column 41 and active base 40 slide in cooperation; guide cross block 42 is installed on the end of guide slide column 41; guide cross block 42 is located on the side of guide turntable 38 near meter box 1; guide groove 43. A guide column 39 is fitted into the guide groove 43, and the two slide together. A guide tooth frame 44 is installed on the guide block 42. A drive gear 45 is installed on the guide base 37 away from the meter box 1. The drive gear 45 and the guide disc 38 rotate together. An electric telescopic column 46 is installed on the winding roller 34 away from the meter box 1. A first large gear 47 is installed on the output end of the electric telescopic column 46. When the electric telescopic column 46 is in its initial state, the first large gear 47 meshes with the drive gear 45. A guide gear 48 is installed on the meter box 1. 48 is located inside the guide gear frame 44, and the two are meshed together; a first pulley 49 is installed on the side of the guide gear 48 away from the meter box 1; a filter plate 50 is installed inside the ventilation hole 7; a drive shaft 51 is installed on the filter plate 50; a second pulley 52 is installed at one end of the drive shaft 51, and a fan blade 53 is installed at the other end; the fan blade 53 is located inside the ventilation hole 7, and the airflow generated by its rotation acts on the meter; a scraper 54 is installed on the drive shaft 51; the scraper 54 contacts the filter plate 50; a transmission belt 55 is connected to the first pulley 49; the transmission belt 55 is connected to the second pulley 52; the transmission belt 55 and the second pulley 52 are in sliding engagement with the first pulley 49;

[0071] When the locking unit is used to remove or install the drive motor 4, the positioning plate 24 reciprocates, synchronously moving the fixing seat 31. Under the action of the cable 35 and the fixed pulley 32, the cable winding roller 34 rotates to unload or wind the cable bundle. This causes the spring spring 36 to be in a buffered, reset state, which helps the cable winding roller 34 wind the unloaded cable 35. Under the action of the electric telescopic column 46, the cable winding roller 34 drives the first large gear 47 to rotate, meshing with the drive gear 45, which in turn drives the guide turntable 38 to rotate. The guide post 39 moves back and forth within the guide groove 43, limiting its movement. This causes the guide block 42 on the guide groove 43 to move back and forth at the active base 40 via the guide post 41. This causes the guide gear frame 44 on the guide block 42 to move back and forth. Due to the different sizes of the gears, the power is transmitted to the guide turntable 38 quickly, causing the guide gear frame 44 to move back and forth rapidly. This causes the guide gear 48 meshing with it to rotate rapidly, driving the first pulley 49 to rotate. Under the action of the transmission belt 55, the second pulley 49 rotates. The pulley 52 rotates rapidly, causing its drive shaft 51 to reciprocate rapidly on the filter plate 50. This causes the fan blades 53 on the drive shaft 51 to reciprocate rapidly within the ventilation holes 7. When the fan blades 53 rotate rapidly in one direction, they dissipate the heat generated by the meters inside the meter box 1 during operation. When the fan blades 53 rotate rapidly in the other direction, they draw in cooling air from the outside into the meter box 1. This cooling air acts around the meters inside the meter box 1, reducing the operating temperature of the meters and preventing overheating during operation. The high temperature affects the performance of the meter, thereby improving its performance and metering accuracy, and further extending its service life. This allows for a reduction in the meter's operating temperature during maintenance or replacement of the drive motor 4. Simultaneously, when the drive shaft 51 rotates on the filter plate 50, the scraper 54 on the drive shaft 51 also rotates continuously on the surface of the filter plate 50 to clean impurities adhering to it. This prevents excessive impurities from affecting the gas flow rate and reducing the heat dissipation effect, thus improving the heat dissipation of the meter.

[0072] In this embodiment, the meter box 1 is also equipped with an impact transducer assembly; the impact transducer assembly includes a limiting slide groove 56, which is disposed through the meter box 1 on the side near the wall; a limiting slider 57, which is fitted into the limiting slide groove 56, and the two slide in cooperation; one end of the stop rotating shaft 18 away from the stop gear 19 passes through the limiting slider 57 and is connected to a directional rotating shaft 58; a telescopic base 59 is installed on the limiting slider 57; the telescopic base 59 is provided with a through directional cylinder 60 on the side near the limiting slider 57. The directional cylinder 60 and the telescopic base 59 are rotatably fitted together; the directional shaft 58 is fitted into the directional cylinder 60; the protrusion on the outer wall of the directional shaft 58 fits into the groove on the inner wall of the directional cylinder 60; a second large gear 61 is installed at the end of the directional cylinder 60 away from the directional shaft 58; an elastic square column 62 is installed on the side of the meter box 1 near the wall; a displacement base 63 is installed at the end of the elastic square column 62; the displacement base 63 is rotatably connected to the outer wall of the electric telescopic column 46; the displacement base 63... A driven gear 64 is installed; the driven gear 64 meshes with the second large gear 61; a limit ring 65 is installed on the outer wall of the directional cylinder 60; a semi-annular seat 66 is installed on the displacement base 63; a limiting annular groove 67 is provided on the semi-annular seat 66; the limiting annular groove 67 is located on the moving path of the limit ring 65; the two are engaged, and when the limit ring 65 moves into the limiting annular groove 67, their centers are coaxial; when the electric telescopic column 46 is started, the first large gear 47 moves, so that it is no longer engaged with the main gear 61. The driving gear 45 meshes; the displacement base 63 moves synchronously with the first large gear 47, so that the driven gear 64 on the displacement base 63 meshes with the driving gear 45; when the semi-ring seat 66 moves with the displacement base 63, the limiting annular groove 67 in the semi-ring seat 66 drives the limiting ring 65 to move, so that the directional cylinder 60 on it slides at the directional rotating shaft 58, so as to synchronously drive the second large gear 61 to move, so that it and the driven gear 64 maintain the displacement state synchronously, ensuring that the two mesh.

[0073] When the stop damper is used to protect the meter, the stop plate 10 on the stop damper moves closer to the meter, causing the stop base 17 on the stop plate 10 to move synchronously. The stop base 17 is equipped with a stop rotating shaft 18, which is connected to the limit slider 57. This causes the stop slider 18 to move synchronously within the limit groove 56, causing the directional rotating shaft 58 on the stop rotating shaft 18 to drive the directional cylinder 60 to move closer to the semi-annular seat 66. This causes the limit ring 65 on the directional cylinder 60 to enter the limiting annular groove 67 on the semi-annular seat 66, making the limiting annular groove 67 and the limit ring 65 rotatably connected at this moment, with their centers coaxial. That is, when the stop plate 10 moves to the working position, it causes... The directional cylinder 60 is connected to the displacement base 63. When the meter in the meter box 1 is in use, if the drive motor 4 needs maintenance, the electric telescopic column 46 is kept in its initial state, so that the first large gear 47 on it remains engaged with the drive gear 45. When the drive motor 4 on the meter box 1 does not need maintenance, the electric telescopic column 46 is activated, causing the first large gear 47 to move and disengage from the drive gear 45, so that the two are no longer engaged. When the first large gear 47 moves, it also synchronously drives the displacement base 63 on the electric telescopic column 46 to move, so that the elastic square column 62 on it is in a stretched state. Since the displacement base 63 also drives the semi-annular seat 66 on it to move when it moves, but the limit on the semi-annular seat 66 is... The annular groove 67 is connected to the limiting ring 65 on the directional cylinder 60, which means that when the displacement base 63 moves, it synchronously drives the directional cylinder 60 to move, limiting its movement at the directional shaft 58. At the same time, it keeps the telescopic base 59 in a stretched state until the driven gear 64 on the displacement base 63 meshes with the driving gear 45. At this time, the driven gear 64 is still meshed with the second large gear 61, which switches the power source of the driving gear 45. If the meter is subjected to an external impact during use, the impact force will be fed back to the blocking plate 13 on the blocking buffer, changing the distance between it and the blocking horizontal plate 10. This causes the L-shaped rack 16 on the blocking plate 13 to mesh with the blocking gear 16 on the blocking horizontal plate 10 when it moves. The rotation of the 9th rotation causes the directional shaft 58 to rotate via the stop shaft 18, which in turn causes the directional cylinder 60 to rotate. This causes the limiting ring 65 on the cylinder 60 to rotate within the limiting annular groove 67 on the semi-annular seat 66. This causes the second large gear 61 on the directional cylinder 60 to rotate, which in turn causes the driven gear 64 to rotate. The driven gear 64 then drives the meshing drive gear 45 to rotate. As a result, under the action of the guide disc 38, guide block 42, and transmission belt 55 on the rotating exhaust mechanism, the fan blades 53 are kept rotating to reduce the operating temperature of the meter. In other words, the kinetic energy of the meter under impact during use can be converted into a power source for heat dissipation, reducing the limitations of the meter's use and further improving the meter's performance.When maintenance of the drive motor 4 is required, resetting the electric telescopic column 46 will stop the stop damper from driving the fan blade 53, switching the power source acting on the fan blade 53 to the latch-locked fixed unit.
