Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a vibration-resistant power measurement and control device housing structure. Background Technology

[0002] During the operation of a power system, power measurement and control devices undertake the critical tasks of accurately measuring, controlling in real time, and effectively monitoring power parameters. The stability of their operation directly affects the reliable operation of the power system.

[0003] However, in practical application scenarios such as industrial production workshops and transportation hub substations, power measurement and control devices are often in environments of continuous vibration. Currently, most existing power measurement and control device shell structures only focus on protection functions and lack measures for vibration buffering and isolation. Traditional shell structures often use simple rigid connections to fix the internal measurement and control devices. In a vibration environment, vibration energy will be directly transmitted to the internal measurement and control devices, causing problems such as loosening of internal electronic components and solder joint detachment. This can lead to faults such as measurement data deviation and control function failure, which not only reduces the service life of the power measurement and control device but also poses a serious threat to the stable operation of the power system. Therefore, this utility model proposes a vibration-resistant power measurement and control device shell structure to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a vibration-resistant power measurement and control device housing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration-resistant power measurement and control device housing structure, comprising a base and a measurement and control device body, wherein the measurement and control device body is composed of a housing and an internal measurement and control unit;

[0006] The inner wall of the housing is provided with a vibration-resistant structure, which includes a base plate installed on the inner wall of the housing. The base plate is provided with two sets of fixing blocks, and the two ends of the two sets of fixing blocks are connected to the upper assembly plate through connecting rods.

[0007] The internal measuring and control device is mounted on the assembly plate, and both ends of the assembly plate are connected to the two side walls of the housing via springs;

[0008] The elastic deformation of the spring can absorb and buffer the vibration energy transmitted from the outside to the housing, reducing the impact of vibration on the internal measuring and controlling device.

[0009] Preferably, the vibration-resistant structure further includes a damping mounting base, which is fastened to the inner wall of the housing by bolts, and the spring is mounted on the damping mounting base.

[0010] Preferably, the assembly plate has positioning cavities at both ends, and the spring has positioning blocks at both ends in an integral structure. The screw holes reserved on the positioning blocks are adapted to the positioning cavities at both ends of the assembly plate.

[0011] Preferably, the assembly plate is provided with a partition plate at both ends of the connection portion, which can prevent the screw from scratching or damaging the internal measuring and controlling device when passing through the assembly plate.

[0012] Preferably, the vibration-resistant structure further includes two sets of side supports, which are welded to both sides of the inner wall of the shell respectively. The bottom plate is supported by the side supports on both sides and is fixed to the side supports by bolts.

[0013] Preferably, heat dissipation channels are provided on both sides of the outer casing, and dust collection nets are installed on the outer sides of both ends of the heat dissipation channels.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By setting an anti-vibration structure on the inner side wall of the housing, the elastic deformation of the spring is used to absorb and buffer the vibration energy. Combined with the frame structure composed of connecting rods and fixing blocks, the assembly plate is provided with limiting support, which greatly reduces the transmission of vibration to the internal measuring and control device. Compared with the traditional rigid connection, this structure can effectively avoid problems such as loosening of internal electronic components and solder joint detachment due to vibration, solve the fault hazards of measurement data deviation and control function failure, and significantly improve the stability and reliability of the power measuring and control device in the vibration environment.

[0016] (2) By setting heat dissipation channels on both sides of the outer casing and equipping them with dust collection nets, the internal controller can be efficiently cooled to prevent performance degradation due to heat accumulation. It can also effectively intercept dust to avoid short circuits and other faults caused by dust accumulation. At the same time, the design of the partition plate on the assembly plate prevents the components from being scratched during the installation process. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a vibration-resistant power measurement and control device housing structure, including a base 1 and a measurement and control device body 2. The measurement and control device body 2 is composed of a housing 3 and an internal measurement and control device. The inner side wall of the housing 3 is provided with a vibration-resistant structure 5, which includes a base plate 51 installed on the inner side wall of the housing 3. The base plate 51 is provided with two sets of fixing blocks 54, and the two ends of the two sets of fixing blocks 54 are connected to the upper mounting plate 4 through connecting rods 53. The internal measurement and control device is installed on the mounting plate 4, and the two ends of the mounting plate 4 are also connected to the two side walls of the housing 3 through springs 55. Through the elastic deformation of the springs 55, the vibration energy transmitted from the outside to the housing 3 can be absorbed and buffered, reducing the impact of vibration on the internal measurement and control device.

[0024] By setting an anti-vibration structure 5 on the inner wall of the housing 3, the elastic deformation of the spring 55 is used to absorb and buffer vibration energy. Together with the frame structure composed of the connecting rod 53 and the fixing block 54, it forms a limiting support for the assembly plate 4, which greatly reduces the transmission of vibration to the internal measuring and control device. Compared with the traditional rigid connection, this structure can effectively avoid problems such as loosening of internal electronic components and solder joint detachment due to vibration, solve the fault hazards of measurement data deviation and control function failure, and significantly improve the stability and reliability of the power measuring and control device in the vibration environment.

[0025] Please see Figures 1 to 4 The vibration-resistant structure 5 further includes a vibration-damping mounting base 56, which is fastened to the inner wall of the housing 3 by bolts. The spring 55 is installed on the vibration-damping mounting base 56. Through the structural design of the vibration-damping mounting base 56, the vibration load transmitted by the spring 55 can be distributed to the side wall of the housing 3, thereby improving the reliability of the entire vibration-resistant structure 5.

[0026] Please see Figures 1 to 4The assembly plate 4 has positioning cavities 41 at both ends, and the spring 55 has positioning blocks 57 at both ends in an integral structure. The screw holes reserved on the positioning blocks 57 are adapted to the positioning cavities 41 at both ends of the assembly plate 4.

[0027] Please see Figures 1 to 4 The assembly plate 4 has a spacer plate 411 at both ends of the connection part. The spacer plate 411 can prevent the screw from scratching or damaging the internal measuring and control device when passing through the assembly plate 4.

[0028] Please see Figures 1 to 4 The vibration-resistant structure 5 also includes two sets of side support frames 52. The two sets of side support frames 52 are welded to the inner walls of the shell 3 on both sides. The bottom plate 51 is supported by the side support frames 52 on both sides and is fixed to the side support frames 52 by bolts. The use of the side support frames 52 facilitates the subsequent disassembly of the bottom plate 51.

[0029] Please see Figures 1 to 4 The housing 3 has heat dissipation channels on both sides of the housing, and dust collection nets 31 are installed on both ends of the heat dissipation channels. During the operation of the device, the heat generated by the internal controller is discharged through the heat dissipation channels on both sides of the housing 3 by air convection, so as to realize the heat dissipation inside the device and prevent the performance of the controller from being affected by heat accumulation. The dust collection nets 31 installed on both ends of the heat dissipation channels can intercept external dust particles, prevent dust from entering the housing 3, avoid dust adhering to the surface of internal electronic components, and prevent short circuits, poor heat dissipation and other faults caused by dust accumulation.

[0030] In the vibration-resistant structure 5, the base plate 51 is supported by side brackets 52 welded to the inner wall of the shell 3 on both sides and fixed with bolts to ensure that the base plate 51 is stably installed on the inner wall of the shell 3. Two sets of fixing blocks 54 are installed on the base plate 51, and their two ends are connected to the assembly plate 4 through connecting rods 53 to form a stable frame structure. The positioning blocks 57 at both ends of the spring 55 are adapted to the positioning cavities 41 at both ends of the assembly plate 4, so that the spring 55 is installed at both ends of the assembly plate 4, and the other end is installed on the shock-absorbing mounting base 56 which is fastened to the inner wall of the shell 3 with bolts, thus completing the connection between the vibration-resistant structure 5 and the assembly plate 4. At the same time, spacers are installed at the connection points at both ends of the assembly plate 4. 411. To prevent damage to the internal measuring and control device during subsequent screw installation, when the device is in a vibrating environment, external vibration is transmitted to the housing 3, and the internal measuring and control device on the internal assembly plate 4 shakes. At this time, the spring 55 absorbs and buffers the vibration energy by utilizing its own elastic deformation, reducing the intensity of vibration transmission. Together with the frame structure composed of the fixing block 54, the connecting rod 53 and the assembly plate 4, it plays a limiting and supporting role for the assembly plate 4, preventing the assembly plate 4 from excessive displacement under the action of the spring 55, further weakening the impact of vibration on the assembly plate 4 and the internal measuring and control device installed on it, thereby effectively protecting the internal electronic components and preventing problems such as loosening and solder joint detachment.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
