Description

Technical Field

[0001] This utility model relates to the field of power meter technology, specifically to the modular structure of power meters. Background Technology

[0002] In the operation and management of power systems, power meters, as key intelligent terminal devices, are not only an important component of the power grid's "sensory nerves" but also a fundamental carrier for realizing digital operation and maintenance. Through high-precision sensors and advanced signal processing technology, they can perform sub-millisecond sampling and dynamic calibration of more than 30 core power parameters, such as voltage, current, and power factor, providing strong data support for the stable and efficient operation of the power system.

[0003] Chinese Patent Publication No. CN220626435U discloses a mounting base for an electric meter, comprising a mounting base body, positioning seats, a cover plate, and a limiting plate. The mounting base body has a receiving cavity extending through both ends. Multiple positioning seats are spaced apart along the circumference of the mounting base body on the inner wall of the receiving cavity. The electric meter can be slidably connected to each positioning seat and elastically abutted and fixed to each positioning seat. The cover plate is detachably connected to one end of the mounting base body. The limiting plate is located at the other end of the mounting base body, and the electric meter is clamped between the cover plate and the limiting plate. This utility model achieves circumferential elastic fixed installation of the electric meter, facilitating the installation and disassembly of the electric meter; the electric meter can be clamped between the cover plate and the limiting plate, achieving axial limiting and fixing of the electric meter.

[0004] In the existing technology, the mounting base and the cavity structure are fixed during the use of a power meter mounting base, and the positioning seats are arranged at intervals along the circumference, which lacks adjustability. If multiple power meters need to be placed, the space cannot be expanded by simply adding or removing components. The overall structure must be redesigned, and the adaptability to diverse scenarios is weak. Therefore, we make an improvement and propose a modular structure based on power meters. Utility Model Content

[0005] The purpose of this utility model is to address the problem that the adaptability of the current mounting structure for power meters is significantly limited.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] Based on the modular structure of power meters, the combination of square plugs and sliding grooves allows for flexible expansion of the storage space by increasing the number of U-shaped connectors, easily adapting to the placement needs of multiple power meters or adding new functional modules, thereby improving the aforementioned problems.

[0008] The application is as follows:

The moving plate has two L-shaped short plates fixedly installed on the top of one of the T-shaped moving plates, and two L-shaped long plates fixedly installed on the top of the other T-shaped moving plate. Adjacent L-shaped short plates and L-shaped long plates are respectively arranged on the corresponding sides of several square inserts. Two insert rods are fixedly installed on the side of the adjacent L-shaped short plates and L-shaped long plates that are close to each other. The insert rods are inserted into the inside of the square inserts and slidably connected to them. Several return springs are fixedly installed on the side of the adjacent L-shaped short plates and L-shaped long plates that are far from each other. The ends of the several return springs that are far from the square inserts are fixedly connected to the base and the U-shaped connecting seat.

[0010] As a preferred technical solution of this application, several of the L-shaped short plates, L-shaped long plates and insert rods are slidably connected to the base and the U-shaped connecting seat. Grooves are provided at the top and bottom of the inner walls of the base and the U-shaped connecting seat. Several of the T-shaped moving plates are inserted into the grooves and slidably connected to them.

An auxiliary plate is fixedly installed on one side of the inner wall of the base and the U-shaped connecting seat, and the U-shaped side plate is slidably connected to the auxiliary plate.

[0012] As a preferred technical solution of this application, both the first baffle and the connecting baffle are provided with a limiting structure. The limiting structure includes two T-shaped sliding plates and a fixing rod. The two T-shaped sliding plates are slidably connected to the first baffle and the connecting baffle. The two fixing rods are respectively disposed inside the two T-shaped sliding plates, and the fixing rods pass through the T-shaped sliding plates and are slidably connected to them. The two fixing rods are fixedly connected to the first baffle and the connecting baffle. Compression springs are provided on the outer side of the two fixing rods and on the side of the two T-shaped sliding plates that are far apart from each other. The ends of the two compression springs that are close to each other are fixedly connected to the two T-shaped sliding plates. The ends of the two compression springs that are far apart from each other are fixedly connected to the first baffle and the connecting baffle. Rubber pads are fixedly installed on the side of the two T-shaped sliding plates that are close to each other.

[0013] As a preferred technical solution of this application, connecting blocks are fixedly installed on the side of the connecting baffle away from the first baffle and on the corresponding sides of the first baffle. A connecting groove that mates with the connecting block is opened at the end of the connecting baffle near the first baffle. A plurality of the connecting blocks are inserted into the interior of the base and the U-shaped side plate and slidably connected thereto. A fixing bolt is provided on one side of the base and the U-shaped side plate. The fixing bolt is inserted into the interior of the base and the U-shaped side plate and slidably connected thereto.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] (1) The U-shaped side plate is connected by the same square plug and sliding groove. When it is necessary to expand the housing space of the power meter or add functional modules, the number of U-shaped connectors can be increased to adapt the structure to the usage requirements of different scenarios. Furthermore, the sliding connection and the detachable design of the plug rod and square plug are adopted between the components, so that when the U-shaped connector and related base, U-shaped side plate and other components are damaged, the maintenance time is shortened and the operation and maintenance cost of the equipment is reduced.

[0018] (2) By means of the two T-shaped sliding plates under the elastic force of the compression spring, the clamping force on the power meter body can always be applied in opposite directions, so that the structure does not need to design a limit component separately for the specific size of the power meter, which greatly improves the compatibility of the entire modular structure with different models of power meters and enhances the versatility and applicability of the structure.

[0031] Example 1: Please refer to the appendix of the instruction manual. Figure 1 -3. Based on the modular structure of the power meter, it includes a base 1 and a power meter body 19. A U-shaped connecting seat 2 is provided on one side of the base 1, and a U-shaped side plate 3 is provided on the side of the U-shaped connecting seat 2 away from the base 1. A first baffle 4 and a connecting baffle 5 are respectively provided on one side of the base 1 and the U-shaped connecting seat 2. Two square plugs 6 are fixedly installed on both sides of the U-shaped connecting seat 2 and the U-shaped side plate 3 near the base 1. Sliding grooves that mate with several square plugs 6 are opened on both the base 1 and the U-shaped connecting seat 2. Several square plugs 6 are slidably connected to the base 1 and the U-shaped connecting seat 2. Two T-shaped movable parts are slidably connected on both sides of the interior of the base 1 and the U-shaped connecting seat 2. Plate 11, one of which has two L-shaped short plates 7 fixedly installed on its top, and the other has two L-shaped long plates 8 fixedly installed on its top. The adjacent L-shaped short plates 7 and L-shaped long plates 8 are respectively arranged on the corresponding sides of several square inserts 6. Two insert rods 9 are fixedly installed on the side of the adjacent L-shaped short plates 7 and L-shaped long plates 8 that are close to each other. The insert rods 9 are inserted into the inside of the square inserts 6 and slidably connected to them. Several return springs 10 are fixedly installed on the side of the adjacent L-shaped short plates 7 and L-shaped long plates 8 that are far from each other. The ends of the several return springs 10 that are far from the square inserts 6 are fixedly connected to the base 1 and the U-shaped connecting seat 2.

[0032] In this embodiment of the utility model, the U-shaped connecting seat 2 on one side of the base 1 and the U-shaped side plate 3 on the outside of the U-shaped connecting seat 2 are initially positioned by the cooperation of the square insert 6 and the sliding groove.

[0033] After the square inserts 6 on both sides of the U-shaped connector 2 and the U-shaped side plate 3 slide into the grooves of the base 1 and the U-shaped connector 2, the T-shaped moving plate 11 inside the base 1 and the U-shaped connector 2 drives the L-shaped short plate 7 and the L-shaped long plate 8 to move. Under the elastic force of the return spring 10, the L-shaped short plate 7 and the L-shaped long plate 8 move closer to the square inserts 6, and the insert rod 9 on one side is inserted into the square inserts 6 to complete the rigid fixation between the components. The first baffle 4 and the connecting baffle 5 restrict the lateral displacement of the power meter body 19 from the side to form a closed assembly space.

[0034] In this embodiment of the utility model, the square insert 6 and the sliding groove are used to achieve quick docking of components and reduce installation difficulty; the combination structure of the insert rod 9 and the return spring 10 ensures the stability of the connection and avoids loosening caused by vibration.

[0035] Example 2: Please refer to the appendix of the instruction manual. Figure 1 -5. As a preferred embodiment of the present invention, several L-shaped short plates 7, L-shaped long plates 8 and insert rods 9 are slidably connected to the base 1 and the U-shaped connecting seat 2. Grooves are provided at the top and bottom of the inner walls of the base 1 and the U-shaped connecting seat 2. Several T-shaped movable plates 11 are inserted into the grooves and slidably connected to them.

[0036] Both the base 1 and the U-shaped connecting seat 2 are provided with a number of heat dissipation holes 12, and the heat dissipation holes 12 are opened outward and downward. An auxiliary plate 17 is fixedly installed on one side of the inner wall of both the base 1 and the U-shaped connecting seat 2, and the U-shaped side plate 3 is slidably connected to the auxiliary plate 17.

[0037] Both the first baffle 4 and the connecting baffle 5 are provided with limiting structures. The limiting structures include two T-shaped slide plates 13 and fixed rods 14. The two T-shaped slide plates 13 are slidably connected to the first baffle 4 and the connecting baffle 5. The two fixed rods 14 are respectively located inside the two T-shaped slide plates 13, and the fixed rods 14 pass through the T-shaped slide plates 13 and are slidably connected to them. The two fixed rods 14 are fixedly connected to the first baffle 4 and the connecting baffle 5. Compression springs 15 are provided on the outer side of the two fixed rods 14 and on the side of the two T-shaped slide plates 13 that are far apart from each other. The ends of the two compression springs 15 that are close to each other are fixedly connected to the two T-shaped slide plates 13, and the ends of the two compression springs 15 that are far apart from each other are fixedly connected to the first baffle 4 and the connecting baffle 5. Rubber pads are fixedly installed on the side of the two T-shaped slide plates 13 that are close to each other.

[0038] Connecting blocks 16 are fixedly installed on the side of the connecting baffle 5 away from the first baffle 4 and on the corresponding sides of the first baffle 4. A connecting groove that mates with the connecting blocks 16 is opened at the end of the connecting baffle 5 near the first baffle 4. Several connecting blocks 16 are inserted into the interior of the base 1 and the U-shaped side plate 3 and slidably connected thereto. Fixing bolts are provided on one side of the base 1 and the U-shaped side plate 3. The fixing bolts are inserted into the interior of the base 1 and the U-shaped side plate 3 and slidably connected thereto. The fixing bolts pass through the connecting blocks 16 and are threadedly connected thereto.

[0039] A through-hole plate 18 is fixedly installed on the side of the base 1 and the U-shaped side plate 3 that are far apart from each other. Several rubber rings 20 are fixedly installed on the outer side of the base 1, the U-shaped connecting seat 2 and the U-shaped side plate 3.

[0040] In this embodiment of the utility model, the L-shaped short plate 7, the L-shaped long plate 8 and the insert rod 9 slide along the inner wall of the base 1 and the U-shaped connecting seat 2. At the same time, the T-shaped moving plate 11 is embedded in the grooves at the top and bottom of the base 1 and the U-shaped connecting seat 2 to form a multi-directional guiding structure. The grooves constrain the movement trajectory of the T-shaped moving plate 11 to prevent it from deviating or getting stuck when subjected to force.

[0041] The heat dissipation holes 12 on the base 1 and the U-shaped connecting seat 2 are designed to be inclined outward and downward. When the power meter body 19 is running, the internal heat is naturally discharged through the heat dissipation holes 12. At the same time, the inclination angle can prevent external dust and water droplets from entering. When the U-shaped side plate 3 is assembled, its edge slides along the auxiliary plate 17 on the inner wall of the base 1 and the U-shaped connecting seat 2. The auxiliary plate 17 provides longitudinal support and positioning reference for the U-shaped side plate 3.

[0042] In this embodiment of the utility model, the T-shaped sliding plate 13 on the first baffle 4 and the connecting baffle 5 can slide along the fixed rod 14. The compression spring 15 always applies an inward elastic force to the T-shaped sliding plate 13. When the power instrument body 19 is placed at the bottom of the inner wall of the base 1 and the U-shaped connecting seat 2, the T-shaped sliding plates 13 on both sides move towards the middle under the action of the compression spring 15. The rubber pad on its inner side is in close contact with the surface of the power instrument body 19 to achieve lateral limitation. The fixed rod 14 restricts the movement direction of the T-shaped sliding plate 13 to prevent it from deviating.

[0043] When connecting the first baffle 4 and the connecting baffle 5, the first baffle 4 and the connecting baffle 5 are connected by inserting the connecting block 16 on the side of the first baffle 4 closest to the connecting baffle 5 into the connecting groove opened on the connecting baffle 5. The connecting block 16, which is fixedly installed on the side of the first baffle 4 and the connecting baffle 5 that is far away from each other, is slidably connected to the base 1 and the U-shaped side plate 3. The expansion module is rigidly fixed to the main structure by tightening the fixing bolts through the base 1, the U-shaped side plate 3 and the connecting block 16.

[0044] The through-hole plate 18 on the outer side of the base 1 and the U-shaped side plate 3 is used to fix the overall structure to the mounting surface with the existing bolts. The stable installation of the equipment is achieved by the bolts passing through the through-hole plate 18. The rubber ring 20 on the outer side of the base 1, the U-shaped connecting seat 2 and the U-shaped side plate 3 effectively resists external impacts, disperses impact forces, and prevents components from being damaged or displaced due to collisions.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
