Description

Technical Field

[0001] This utility model relates to the field of electricity metering box technology, specifically to an easy-to-install electricity metering box. Background Technology

[0002] As the core equipment for measuring users' electricity consumption in the power system, electricity metering boxes need to be installed in large numbers on outdoor utility poles (suitable for decentralized electricity consumption scenarios such as residential areas and rural areas). The convenience and stability of their installation process directly affect the efficiency of power operation and maintenance.

[0003] Currently, when installing electricity metering boxes on utility poles, it is necessary to first drill holes in the pole to fix metal brackets, and then connect the metering boxes by welding or bolting. This relies on professional tools such as electric drills and welding machines. When outdoor working space is limited, the operation difficulty increases sharply, and the skill requirements for installers are strict. The installation of a single metering box takes 1-2 hours, which cannot meet the needs of batch installation. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an easy-to-install electricity metering box, solving the problem that the traditional electricity metering box installation method in the industry requires drilling holes in the utility pole to fix a metal bracket, and then connecting the metering box to the bracket by welding or bolts.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a simple-to-install electricity metering box, including a utility pole, two semi-circular sleeves, and an electricity metering box. The two semi-circular sleeves are arranged in a left-right correspondence. A fixed installation component is provided on the two semi-circular sleeves and the electricity metering box. The fixed installation component includes four rectangular plates, which are respectively fixedly connected to the front and rear surfaces of the two semi-circular sleeves. Each of the four rectangular plates has a half-T-shaped groove, and the bottom of each of the four half-T-shaped grooves is fixedly connected to a fixing rod. Two corresponding half-T-shaped grooves will form a T-shaped groove. Two fixing plates are fixedly connected to the upper and lower surfaces of the two semicircular sleeves; Among them, the right side of each of the four fixed plates on the left is fixedly connected with a fixing screw; Each of the four fixing plates on the right side has through holes.

[0006] Preferably, the right side of each of the four fixing screws extends through the inner wall of a corresponding through hole, and the outer wall of each of the four fixing screws is threaded with a fixing nut.

[0007] Preferably, two rectangular support plates are fixedly connected to the left side of the semicircular sleeve on the left side, and the two rectangular support plates are arranged in a front-to-back correspondence.

[0008] Preferably, the upper surfaces of the two rectangular support plates are provided with rectangular slots, and the inner walls of the two rectangular slots are slidably engaged with L-shaped plates.

[0009] Preferably, the left sides of both L-shaped plates are fixedly connected to the power metering box.

[0010] Preferably, two L-shaped fixing plates are fixedly connected to the right side of the power metering box, and T-shaped sliding plates are fixedly connected to the opposite sides of the two L-shaped fixing plates.

[0011] Preferably, the two T-shaped sliding plates are slidably connected to the T-shaped grooves formed by the two corresponding half-T-shaped grooves; Each of the two T-shaped slides has two mounting holes.

[0012] Preferably, the upper ends of the four fixing rods extend through the inner walls of the corresponding mounting holes.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides an easy-to-install electricity metering box, which has the following advantages: By setting up fixed installation components, the entire installation and disassembly process eliminates the need for complex operations such as welding and drilling. It is completed solely through the snap-fit ​​and limiting of the mechanical structure, which greatly reduces the difficulty of on-site operations and shortens the installation time. It is suitable for the rapid installation needs on outdoor utility poles. The snap-fit ​​structure of the L-shaped plate and rectangular slot on the left restricts lateral swaying, while the cooperation of the T-shaped slide plate and T-slot on the right, as well as the fixing rod and the mounting hole, restricts longitudinal displacement and lateral offset. This forms a stable structure with bidirectional limiting and multi-point fixing, ensuring that the electricity metering box is firmly installed on the utility pole and will not loosen or shift due to external forces such as wind and vibration.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a new technical solution: an easy-to-install electricity metering box, including four rectangular plates 8, which are respectively fixedly connected to the front and rear surfaces of two semi-circular sleeves 4. Each rectangular plate 8 has a half T-shaped groove 10. Two corresponding half T-shaped grooves 10 are combined to form a complete T-shaped groove, providing a sliding and limiting channel for the T-shaped slide plate 15.

[0018] Half of the T-shaped groove 10 is opened on the rectangular plate 8. Each half is a half groove structure. The half T-shaped grooves 10 of the left and right semicircular sleeves 4 are combined to form a complete T-shaped groove, which is adapted to the shape of the T-shaped slide plate 15, restricts the lateral displacement of the slide plate, and ensures the accurate installation path of the metering box.

[0019] There are four fixing rods 9, which are fixedly connected to the bottom of the four half-T-shaped grooves 10 respectively. The upper end can pass through the mounting hole 14 of the T-shaped slide plate 15. By cooperating with the mounting hole, the longitudinal and lateral displacement of the T-shaped slide plate 15 is restricted, and the connection of the two semi-circular sleeves 4 is reinforced.

[0020] There are eight fixing plates 7, which are fixedly connected to the upper and lower surfaces of the two semicircular sleeves 4 respectively (two on the upper and two on the lower surface of each semicircular sleeve); the four fixing plates 7 on the left are fixedly connected to the right side by fixing screws 5, and the four fixing plates 7 on the right side are provided with through holes 6, so that the two semicircular sleeves can be docked and fixed by the cooperation of the screws and the through holes.

[0021] There are four fixing screws 5, which are fixedly connected to the right side of the four fixing plates 7 of the left semicircular sleeve 4. The right end can pass through the through hole 6 of the fixing plate 7 of the right semicircular sleeve 4. The outer wall is threaded with a fixing nut. By tightening the nut, the left and right fixing plates 7 are brought into contact, which drives the semicircular sleeve 4 to clamp the utility pole 2.

[0022] There are four through holes 6, which are opened on the four fixing plates 7 of the right semicircular sleeve 4, for the fixing screws 5 to pass through, providing a channel for the semicircular sleeve 4 to be connected, ensuring that the screws can be accurately inserted and fixed by the nuts.

[0023] Four fixing nuts are provided, which are threaded onto the outer walls of the four fixing screws 5. After tightening, the left and right fixing plates 7 are brought close to each other and fit together, thereby making the two semicircular sleeves 4 firmly clamp the utility pole 2 and preventing the semicircular sleeves from sliding or rotating.

[0024] There are two rectangular support plates 11, which are fixedly connected to the left side of the left semicircular sleeve 4, one in front and one behind. A rectangular slot 12 is provided on the upper surface to support the L-shaped card plate 13 and provide it with a carding space, thereby limiting the position of the power metering box 1 from the left side.

[0025] A rectangular slot 12 is formed on the upper surface of the rectangular support plate 11, and its inner wall is slidably engaged with the L-shaped card plate 13. By tightly fitting together, the lateral displacement of the L-shaped card plate 13 is restricted, thereby preventing the power metering box 1 from wobbling left and right during use.

[0026] There are two L-shaped card plates 13. The left one is fixedly connected to the electricity metering box 1, and the right one is slidably engaged with the inner wall of the rectangular card slot 12, connecting the electricity metering box with the left semi-circular sleeve 4, and cooperating with the rectangular card slot to achieve stable positioning of the left side of the metering box.

[0027] There are two L-shaped fixing plates 3, which are fixedly connected to the right side of the electricity metering box 1. The opposite side is fixedly connected to the T-shaped sliding plate 15, which supports the T-shaped sliding plate and connects the metering box to the sliding plate, providing a structural foundation for the installation of the metering box on the right side.

[0028] There are two T-shaped sliding plates 15, which are fixedly connected to the opposite sides of the two L-shaped fixed plates 3 respectively, and are slidably connected to the complete T-shaped groove formed by the two half-T-shaped grooves 10. The T-shaped structure restricts the lateral displacement of the metering box and ensures stable sliding along the groove during installation.

[0029] There are four mounting holes 14, which are respectively opened on the two T-shaped slide plates 15 (two on each slide plate) for the upper end of the fixing rod 9 to pass through. By cooperating with the fixing rod, the position of the T-shaped slide plate is further fixed, limiting the longitudinal and lateral displacement of the metering box and forming a two-way limit.

[0030] Furthermore, when using this easily installed electricity meter box, when the electricity meter box 1 is installed on the utility pole 2; First, place the two semicircular sleeves 4 on the left and right sides of the power metering box 2 respectively, so that the four fixing screws 5 correspond to the through holes 6 respectively, and then move the two semicircular sleeves 4 to the relative positions. When the two semicircular sleeves 4 are moved to their relative positions, the inner walls of the two semicircular sleeves 4 will gradually fit against the outer wall of the utility pole 2 (the semicircular sleeves 4 are adapted to the circular structure of the utility pole to ensure a tight fit); at the same time, the four fixing screws 5 on the left semicircular sleeve 4 will pass through the through holes 6 on the corresponding fixing plate 7 of the right semicircular sleeve 4 until the two semicircular sleeves 4 completely wrap around the utility pole 2, providing a basic positioning for the subsequent fixing of the semicircular sleeves 4; When the two semicircular sleeves 4 are completely fitted into the utility pole 2, the corresponding half of the T-shaped groove 10 will simultaneously form a complete T-shaped groove. Among them, fixing nuts are screwed onto the outer walls of the four fixing screws 5 respectively. By tightening the fixing nuts, the fixing plates 7 on the left and right sides are brought closer to each other and fit tightly together, thereby driving the two semi-circular sleeves 4 to firmly clamp the utility pole 2, preventing the semi-circular sleeves 4 from sliding or rotating along the utility pole 2, thus completing the fixed installation of the semi-circular sleeves 4 on the utility pole 2. After the semicircular sleeve 4 is fixed, the power metering box 1 is picked up so that the two T-shaped sliding plates 15 correspond to the two complete T-shaped slots, and the two L-shaped card plates 13 correspond to the two rectangular card slots 12. Then the power metering box 1 is moved downward. When the electricity metering box 1 is moved downwards, the two T-shaped sliding plates 15 will slide synchronously along the inner wall of the corresponding complete T-shaped groove. The matching structure between the T-shaped groove and the T-shaped sliding plate 15 can strictly limit the lateral displacement of the electricity metering box 1, avoid the box from shifting left and right during the movement, and ensure the accuracy of the installation path. At the same time, the two L-shaped clamping plates 13 will slide into the inner wall of the rectangular clamping groove 12 of the corresponding rectangular support plate 11 as the box moves downwards. The inner wall of the rectangular clamping groove 12 is tightly fitted with the L-shaped clamping plate 13, forming a lateral limit on the electricity metering box 1 from the left side to prevent the box from swaying left and right during subsequent use. As the power metering box 1 continues to move downwards, until the mounting hole 14 on the T-shaped slide plate 15 is aligned with the fixing rod 9 at the bottom of the T-shaped groove, the upper ends of the four fixing rods 9 will simultaneously penetrate the inner wall of the corresponding mounting hole 14. The cooperation between the fixing rod 9 and the mounting hole 14 can directly restrict the left and right displacement of the T-shaped slide plate 15, and at the same time, it can also cooperate with the corresponding two fixing rods 9 to start the reinforcement of the two semi-circular sleeves 4. When the fixing rod 9 is fully inserted through the mounting hole 14, the installation position of the power metering box 1 is completely fixed. The interlocking structure of the left L-shaped card plate 13 and the rectangular card slot 12 restricts lateral swaying. The cooperation between the right T-shaped sliding plate 15 and the T-shaped slot, the fixing rod 9 and the mounting hole 14 restricts longitudinal displacement and lateral offset, forming a stable structure with bidirectional limiting and multi-point fixing, ensuring that the power metering box 1 is firmly installed on the utility pole 2 and will not loosen or shift due to external forces such as wind or vibration. If the electricity metering box 1 needs to be repaired or disassembled later, simply lift the box upwards to disengage the fixing rod 9 from the mounting hole 14 and the L-shaped clamping plate 13 from the rectangular clamping groove 12. Then pull the box away from the utility pole 2 so that the T-shaped sliding plate 15 slides out of the T-shaped groove and the box can be removed. The entire installation and disassembly process does not require complex operations such as welding and drilling. It is completed only by the mechanical structure of clamping and limiting, which greatly reduces the difficulty of on-site operation, shortens the installation time, and meets the needs of rapid installation on outdoor utility poles.

[0031] Example 1: Application in coastal high-wind environments after replacing the semi-circular sleeve 4 with anti-slip teeth. Scene background A coastal residential area needs to install an electricity meter box 1 on a utility pole 2. The area experiences winds of force 5-7 year-round. The original smooth inner wall semicircular sleeve 4, after clamping the utility pole, is prone to "slow slippage" due to wind vibration (approximately 5mm slippage per month, loosening rate 18%). After slippage, the electricity meter box 1 tilts, which not only affects the meter reading (angle deviation causes reading error ±3%), but may also pull on the internal wiring, posing a short circuit risk. To prevent slippage, monthly reinforcement is required (30 minutes per unit), resulting in high maintenance costs. Therefore, the original semicircular sleeve 4 is replaced with a "semicircular sleeve with arc-shaped anti-slip teeth". The inner wall has 3 evenly distributed arc-shaped anti-slip teeth (tooth height 1.5mm, tooth pitch 3mm, material is wear-resistant manganese steel). The fixed connection with the rectangular plate 8 and the fixing plate 7 is retained. The overall diameter of the semicircular sleeve 4 is the same as the original, which does not affect the fit between the fixing screw 5 and the through hole 6. The arc-shaped anti-slip teeth can be embedded into the wooden / concrete surface of the utility pole 2 (the biting force is increased by 3 times), the slippage is reduced from 5mm / month to less than 0.2mm / month, and the loosening rate is reduced from 18% to 1%; the electricity metering box 1 always remains horizontal, the reading error is reduced from ±3% to ±0.5%, avoiding the risk of short circuit caused by wiring pulling, and is suitable for the high wind outdoor environment along the coast. Furthermore, the semicircular sleeve 4 with anti-slip teeth can still precisely match the original fixing screw 5 and through hole 6. After tightening the fixing nut, the anti-slip teeth fit tightly against the surface of the utility pole, without affecting the clamping force of the two semicircular sleeves (the original clamping force was 120N, now it is 130N, which is still within the safe range). The installation position of the rectangular plate 8 and the size of half of the T-shaped groove 10 remain unchanged, and the T-shaped sliding plate 15 can be installed normally without modifying other parts.

[0032] Example 2: Application in low-temperature freezing and heave environments in northern regions after replacing the semi-circular sleeve 4 with an elastic rubber pad. Scene background In a northern city during winter (-20℃ to -5℃), an electricity metering box 1 needs to be installed on a concrete utility pole 2. Due to frost heave (1-2mm / time), the rigid steel semi-circular sleeve 4, after being clamped, is easily "spread out" during frost heave (the gap increases from 0.2mm to 1mm). After thawing, it cannot spring back, causing the semi-circular sleeve 4 to loosen (slippage rate 22% / month). After loosening, the electricity metering box 1 tilts (tilt angle ≤3°), which not only affects the meter reader's reading (requiring bending over to adjust the viewing angle, increasing the time by 5 seconds / unit), but may also pull on the internal wiring terminals, posing a risk of poor contact. To solve this problem, reinforcement needs to be carried out every two weeks (each reinforcement takes 15 minutes per unit). During the winter, the maintenance pressure is high. At this time, the semicircular sleeve 4 is replaced with a "semicircular sleeve with an elastic rubber pad". A 2mm thick low-temperature resistant EPDM rubber pad (temperature resistance -40℃ to 80℃) is attached to the inner wall of the semicircular sleeve 4. The welding fixation with the fixing plate 7 and the rectangular plate 8 is retained. The outer diameter of the semicircular sleeve 4 and the mounting hole position of the fixing screw 5 are the same as the original. The elastic rubber padding layer deforms synchronously with the frost heave of the utility pole (deformation rate ≤10%), preventing the semi-circular sleeve 4 from being stretched open (the gap remains at 0.2-0.3mm after frost heave). After thawing, the padding layer rebounds, and the clamping force of the semi-circular sleeve 4 remains stable (original clamping force 120N, still ≥110N after frost heave). The slippage rate decreases from 22% / month to 1.5% / month. The tilt angle of the electricity metering box 1 is ≤0.5°, eliminating the need for meter readers to adjust their viewing angle. The meter reading time per unit is reduced by 5 seconds, and the meter reading efficiency in winter is improved by 15%. Furthermore, the rubber pad does not change the external dimensions of the semicircular sleeve 4, and the fixing screw 5 of the left semicircular sleeve 4 can still accurately penetrate the through hole 6 of the right semicircular sleeve 4. After tightening the fixing nut, the pad is evenly compressed, further enhancing the fit between the semicircular sleeve and the utility pole 2 (the fit rate increases from 85% to 98%). The position of half of the T-groove 10 of the rectangular plate 8 remains unchanged, and the T-shaped sliding plate 15 can be slidably installed without affecting the fixing process of the metering box.

[0033] Example 3: Application of a utility pole with uneven thickness after replacing the adjustable-width semicircular sleeve 4 Scene background In a rural power grid renovation project, the diameters of utility poles varied significantly (150mm, 180mm, and 200mm). The original semicircular sleeve 4 was a fixed size (only compatible with 180mm diameter poles). During installation, three different sizes of semicircular sleeves were required for different diameter poles, leading to complex inventory management (requiring an additional 30% of storage space). Furthermore, when encountering non-standard diameter poles (such as 160mm), metal shims were needed (8 minutes per unit), and these shims were prone to falling off, causing the semicircular sleeves to loosen (15% loosening rate). To address this, the semicircular sleeve 4 was replaced with an "adjustable width semicircular sleeve." This sleeve consists of a "fixed section" and a "telescopic section." The fixed section is fixed to the fixing plate 7 and the rectangular plate 8. The telescopic section is connected to the fixed section via two adjusting bolts, with an adjustment range of 140-210mm, covering all pole diameters in the project. The mating structure of the fixing screw 5 and the through hole 6 is retained. The adjustable semicircular sleeve 4 allows for free width adjustment within the range of 140-210mm by turning the adjusting bolt, eliminating the need to stock multiple specifications (reducing the number of stock specifications from 3 to 1), saving 30% of storage space; when encountering non-standard diameter utility poles, no metal shims are required, and the adjustment time is only 2 minutes per unit, improving installation efficiency by 75%; after adjustment, the gap between the semicircular sleeve and the utility pole is ≤0.5mm, reducing the loosening rate from 15% to below 1%, making it suitable for various specifications of utility poles in rural areas; Furthermore, the position of the fixing plate 7 of the adjustable semicircular sleeve 4 and the number of fixing screws 5 are the same as before, and the through hole 6 of the right semicircular sleeve 4 can still be precisely matched with the left fixing screw 5; after tightening the fixing nut, the adjusting bolt and the fixing screw form a "double fixation", the clamping force of the semicircular sleeve is increased by 20% (up to 144N) compared with the original, the wind vibration resistance of the power metering box 1 is enhanced, and it is suitable for complex outdoor installation environments.
