Description

Technical Field

[0001] This utility model relates to the field of installation structure technology, specifically a fixed structure for a power distribution data acquisition device. Background Technology

[0002] In the power distribution segment of a power system, distribution data acquisition devices are key equipment for monitoring, metering, and transmitting power parameters. Their main function is to collect electrical parameters such as voltage, current, power, and frequency in distribution lines in real time, and to record and upload equipment operating status and fault information. This provides data support for power dispatching, load management, fault diagnosis, and energy efficiency analysis, and is an important component in building a smart distribution network.

[0003] Currently, the mounting method for power distribution data acquisition devices needs to be flexibly selected according to the installation scenario (such as inside a distribution box, on a utility pole, on a wall surface, etc.). Common mounting structures mainly include the following types:

[0004] 1. By using the pre-drilled mounting holes on the device housing, expansion bolts or ordinary bolts can be used to directly fix the device to a hard surface such as a wall or the inner wall of a distribution box.

[0005] 2. For cylindrical carriers such as utility poles, a semi-circular clamp is used to wrap the device housing and the carrier, and the clamp is tightened with bolts to achieve fixation.

[0006] However, the existing fixed structure still has the following shortcomings:

[0007] Existing fixing methods are usually designed for a single type of mounting surface (such as a plane or a cylindrical surface), which makes it difficult to meet the diverse installation needs in complex power distribution scenarios. When changing the installation location, the fixing structure needs to be re-adapted, which increases construction costs and time. Utility Model Content

[0008] The purpose of this invention is to provide a fixed structure for a power distribution data acquisition device to solve the problems mentioned in the background art.

[0009] The objective of this utility model can be achieved through the following technical solutions:

[0010] A fixed structure for a power distribution data acquisition device includes:

[0011] The mounting plate has a mounting groove on its back and protrusions at both ends on its top and bottom surfaces.

[0012] A clamping mechanism fixedly installed in the mounting groove is used to fix the mounting plate onto the columnar structure;

[0013] Two mating seats are fixedly installed on the front of the mounting plate;

[0014] And a docking assembly that is bolted to the back of the power distribution data acquisition device housing, used to cooperate with the docking seat to achieve quick disassembly between the power distribution data acquisition device housing and the mounting plate.

[0015] Furthermore, the clamping mechanism includes a fixed seat, and a fixed seat is fixedly installed at the middle position of both ends of the side of the mounting groove one. A bidirectional lead screw is rotatably installed between the two fixed seats. Two sliding blocks are symmetrically distributed about the middle position of the bidirectional lead screw and are threaded through the periphery of the bidirectional lead screw. The sliding blocks are in sliding contact with the mounting groove one.

[0016] The slide block has mounting seats fixedly installed at both ends on the side near the middle of the bidirectional lead screw. A mounting shaft is installed between the two mounting seats in a damped rotatable manner. A clamping plate is fixedly installed around the mounting shaft.

[0017] One end of the bidirectional lead screw rotates through the corresponding fixed seat and is then fixedly installed with a column. The end of the column away from the bidirectional lead screw has a hexagonal groove.

[0018] Furthermore, the inner side of the clamp is provided with a V-shaped groove, and the inner side of the clamp is covered with an anti-slip layer.

[0019] Furthermore, the docking seat includes a hollow column fixedly installed on the front of the mounting plate. Two symmetrically distributed mounting grooves are opened in the middle of the inner wall of the hollow column. A snap-fit ​​block is slidably installed in the mounting groove. A spring is fixedly installed between the snap-fit ​​block and the inner end face of the mounting groove. The end of the snap-fit ​​block away from the spring extends into the hollow column, and the end of the snap-fit ​​block located in the hollow column has inclined surfaces at both the upper and lower corners.

[0020] Furthermore, the docking assembly includes a connecting plate, a connecting hole for installing bolts is provided at the center of the side of the connecting plate, and insert rods are fixedly installed at both ends of the side of the connecting plate. A snap-fit ​​post is fixedly installed at the end of the insert rod away from the connecting plate, and a sealing ring is installed at the center of the periphery of the snap-fit ​​post.

[0021] The beneficial effects of this utility model are:

[0022] 1. This utility model solves the problem that existing fixing methods are only suitable for a single type of installation carrier by setting up a clamping mechanism. This structure can be flexibly installed on planes (such as walls, the inner wall of distribution boxes) and columnar structures (such as utility poles) without the need to adapt the fixing structure.

[0023] 2. In the clamping mechanism of this utility model, the bidirectional screw drives the slide to move, so that the clamping plate can reliably clamp the column; the V-groove on the inner side of the clamping plate increases the contact area and positions it, and the anti-slip layer increases the friction, further ensuring the stability of the installation on the column structure.

[0024] 3. This utility model achieves quick disassembly between the housing and mounting plate of the power distribution data acquisition device through the cooperative design of the docking components and the docking seat, which facilitates the maintenance and replacement of the equipment.

Detailed Implementation

[0037] 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.

[0038] Example 1:

[0039] Please see Figures 1-4 In this embodiment of the utility model, a fixing structure for a power distribution data acquisition device includes:

[0040] Mounting plate 1, the back of mounting plate 1 is provided with mounting groove 7, and the top and bottom surfaces of mounting plate 1 are provided with protrusions 5 at both ends;

[0041] A clamping mechanism fixedly installed in the mounting groove 7 is used to fix the mounting plate 1 onto the columnar structure;

[0042] Two mating seats are fixedly installed on the front of the mounting plate 1;

[0043] And a docking assembly that is bolted to the back of the housing 3 of the power distribution data acquisition device, which is used to cooperate with the docking seat to achieve quick disassembly between the housing 3 of the power distribution data acquisition device and the mounting plate 1.

[0044] When installing on a flat surface, close the clamping mechanism, place the back of the mounting plate 1 close to the mounting surface, and fix it by installing bolts between the boss 5 and the flat surface;

[0045] When installing on the columnar structure, open the clamping mechanism and clamp the column to fix it in place. At the same time, by utilizing the cooperation between the docking assembly and the docking seat, the housing 3 of the power distribution data acquisition device and the mounting plate 1 can be quickly disassembled.

[0046] This utility model achieves flexible installation in two different installation scenarios, namely planar and columnar structures, through the coordinated arrangement of mounting plate 1, clamping mechanism, docking seat and docking component, without the need to replace the fixed structure, thus reducing construction costs and time;

[0047] By combining the docking components with the docking base, the ease of disassembling the power distribution data acquisition device is improved, and the practicality of the overall structure is enhanced.

[0048] Example 2:

[0049] Please see Figures 3-5 Based on embodiment 1, the clamping mechanism includes a fixed seat 8. Fixed seats 8 are fixedly installed at the middle positions of both ends of the side of the mounting groove 7. A bidirectional lead screw 13 is rotatably installed between the two fixed seats 8. Two slides 11 are symmetrically distributed about the middle position of the bidirectional lead screw 13 and are threaded through the periphery of the bidirectional lead screw 13. The slides 11 are in sliding contact with the mounting groove 7.

[0050] The slide block 11 is fixedly installed at both ends on the side near the middle position of the double-acting screw 13. A mounting shaft 15 is installed between the two mounting shafts 14 in a damped rotatable manner. A clamping plate 12 is fixedly installed on the periphery of the mounting shaft 15.

[0051] After one end of the bidirectional lead screw 13 rotates through the corresponding fixed seat 8, a column 9 is fixedly installed. A hexagonal groove 10 is provided at the end of the column 9 away from the bidirectional lead screw 13.

[0052] When closed, the two slides 11 are at both ends of the mounting groove 7, and the clamping plate 12 is parallel to the mounting plate 1 and located in the mounting groove 7. When open, rotate the clamping plate 12 to be perpendicular to the mounting plate 1, and use a hex wrench to rotate the double-ended screw 13 through the hexagonal groove 10 to bring the two slides 11 closer together, so that the clamping plate 12 clamps the column and completes the fixing of the mounting plate 1 on the column.

[0053] The clamping mechanism provided in this embodiment moves the slide block 11 by rotating the bidirectional lead screw 13, thereby driving the clamping plate 12 to clamp the column, which is simple and convenient to operate;

[0054] The clamp 12 can be rotated with damping, which can prevent the clamp 12 from moving randomly. When not in use, the clamp 12 can be stored in the mounting slot 7 without taking up extra space.

[0055] Example 3:

[0056] Please see Figure 6 Based on embodiment 2, the inner side of the clamping plate 12 is provided with a V-shaped groove 23, and the inner side of the clamping plate 12 is covered with an anti-slip layer 24.

[0057] A V-shaped groove 23 is formed on the inner side of the clamping plate 12, and an anti-slip layer 24 is covered thereon. The V-shaped groove 23 increases the contact area with the columnar structure, and the anti-slip layer 24 increases the friction. The two work together to enhance the clamping effect of the clamping plate 12 on the column.

[0058] In this invention, the V-groove 23 not only increases the contact area but also positions the column structure, making the clamping more stable; the anti-slip layer 24 effectively prevents relative sliding between the column and the clamping plate 12, further improving the stability of the installation.

[0059] Example 4:

[0060] Please see Figure 1 , Figure 2 and Figures 7-9 Based on embodiment 1, the docking seat includes a hollow column 4 fixedly installed on the front of the mounting plate 1. Two symmetrically distributed mounting grooves 19 are opened in the middle of the inner wall of the hollow column 4. A snap-fit ​​block 21 is slidably installed in the mounting groove 19. A spring 20 is fixedly installed between the snap-fit ​​block 21 and the inner end face of the mounting groove 19. The end of the snap-fit ​​block 21 away from the spring 20 extends into the hollow column 4, and the end of the snap-fit ​​block 21 located in the hollow column 4 is provided with inclined surfaces 22 at both the upper and lower corners.

[0061] The docking assembly includes a connecting plate 2. A connecting hole 6 for installing bolts is opened in the middle of the side of the connecting plate 2. Insert rods 16 are fixedly installed at both ends of the side of the connecting plate 2. A snap-fit ​​post 18 is fixedly installed at the end of the insert rod 16 away from the connecting plate 2. A sealing ring 17 is installed in the middle of the periphery of the snap-fit ​​post 18.

[0062] During installation, the connecting plate 2 is fixed to the back of the device housing 3 with bolts. The locking pin 18 is pushed into the hollow pin 4, and the locking block 21 is reset under the action of the spring after being compressed, thus achieving axial limiting. During disassembly, the device housing 3 can be pulled out directly. The sealing ring 17 seals the open end of the hollow pin 4 when in the docking state.

[0063] In this invention, the cooperation between the docking component and the docking seat enables the rapid installation and disassembly of the device housing and the mounting plate, thereby improving the efficiency of maintenance and replacement.

[0064] The sealing ring 17 seals the open end of the hollow column 4, preventing dust and moisture from entering, protecting the internal structure, and extending its service life.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
