Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a data acquisition device for a distributed photovoltaic power station with protective functions. Background Technology

[0002] In the operation system of distributed photovoltaic power stations, data acquisition devices are crucial. In order to accurately collect various key data, they are usually installed near the distributed photovoltaic power station to ensure the stable and efficient operation of the power station.

[0003] In existing technologies, traditional distributed photovoltaic (PV) power station data acquisition devices are typically transported in truck cargo compartments, where vibrations from road bumps continuously act on the device. During installation and use, to achieve better data acquisition results, the data acquisition device may be installed near large equipment, such as large motors and transformers in industrial plants. The strong vibrations generated by these devices during operation are transmitted to the data acquisition device through the ground and air. As a core component, the data processor is subjected to prolonged vibration. The internal fixing bolts or clamps gradually loosen due to continuous high-frequency vibration impacts. This loosening damages the stability of the internal component connections, potentially leading to abnormal data transmission, calculation errors, and even data loss in severe cases. This significantly interferes with the data monitoring and analysis of distributed PV power stations. Therefore, there is an urgent need for a protective distributed PV power station data acquisition device to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a distributed photovoltaic power station data acquisition device with protective function, so as to solve the problem mentioned in the background art that the vibration generated by the surrounding environment during transportation and when installed near large equipment directly acts on the data processor for a long time, causing the fixing bolts or fixing blocks inside the processor to loosen.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a distributed photovoltaic power station data acquisition device with protective function, including a main body box, a data processor is installed inside the main body box, and a vibration damping and protection component is installed inside the main body box;

[0006] The vibration damping and protection assembly includes a mounting box, which is located inside the main body box. The bottom surface of the data processor is fixedly connected to the inner wall of the mounting box. The bottom surface of the main body box has multiple limiting grooves, and rotating balls are rotatably connected to the inner walls of the limiting grooves. Support plates are provided on the surfaces of the multiple rotating balls. A connecting rope is fixedly connected to the bottom surface of the mounting box. The surface of the connecting rope is movably sleeved with the inner wall of the support plate. A damping block is fixedly connected to the lower end of the connecting rope.

[0007] Preferably, the bottom surface of the receiving plate is fixedly connected to a plurality of fixed posts, the bottom surface of the main body box is provided with a plurality of sliding holes, the inner wall of the sliding holes is slidably connected to a sliding seat, the inner wall of the sliding seat is slidably connected to the surface of the fixed posts, and a spring is sleeved on the surface of the fixed posts.

[0008] Preferably, the inner wall of the mounting box is provided with a plurality of first fixing grooves, and a first polar block is fixedly connected to the inner wall of the first fixing groove. The periphery of the mounting box is provided with a second fixing groove, and a second polar block is fixedly connected to the inner wall of the second fixing groove.

[0009] Preferably, the main body box has multiple flow holes on its periphery, and the multiple flow holes are matched in size.

[0010] Preferably, the top surface of the main body box is provided with a clearance groove, and the inner wall of the clearance groove is provided with a baffle plate.

[0011] Preferably, the dimensions of the plurality of first polarity blocks and the second polarity blocks are matched, and the polarity directions of the first polarity blocks and the second polarity blocks are set opposite.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating vibration damping and protection components, when ground vibrations are transmitted to the mounting box, the damping blocks on the bottom of the mounting box shake and the rotating ball rotates as the mounting box moves, thus dissipating the force generated by the vibrations. This keeps the data processor and the mounting box relatively stationary, thereby preventing the energy generated by ground vibrations from directly acting on the data processor and causing bolts or clips and other fasteners inside the data processor to fall off.

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a data acquisition device for a distributed photovoltaic power station with protective functions, including a main body box 1. A data processor 2 is installed inside the main body box 1. A vibration damping and protection component 3 is also installed inside the main body box 1. The vibration damping and protection component 3 includes a mounting box 301, which is located inside the main body box 1. The bottom surface of the data processor 2 is fixedly connected to the inner wall of the mounting box 301. Multiple limiting grooves 302 are formed on the bottom surface of the main body box 1. Rotating balls 303 are rotatably connected to the inner walls of the limiting grooves 302. Support plates 304 are provided on the surfaces of the multiple rotating balls 303. A connecting rope is fixedly connected to the bottom surface of the mounting box 301. 305, the surface of the connecting rope 305 is movably sleeved with the inner wall of the receiving plate 304, and the lower end of the connecting rope 305 is fixedly connected to a damping block 306. Through the vibration reduction and protection component 3, when the ground vibration is transmitted to the mounting box 301, the damping block 306 on the bottom surface of the mounting box 301 shakes and the rotating ball 303 rotates when the mounting box 301 moves, thereby consuming the force generated by the vibration. This keeps the data processor 2 and the mounting box 301 relatively stationary, thereby preventing the energy generated by the ground vibration from directly acting on the data processor 2 and causing the bolts or clips and other fasteners of the internal components of the data processor 2 to fall off.

[0022] Furthermore, multiple fixed posts 307 are fixedly connected to the bottom surface of the receiving plate 304, and multiple sliding holes 308 are opened on the bottom surface of the main body box 1. A sliding seat 309 is slidably connected to the inner wall of the sliding hole 308. The inner wall of the sliding seat 309 is slidably connected to the surface of the fixed post 307. A spring 310 is sleeved on the surface of the fixed post 307. The sliding seat 309, the fixed post 307 and the spring 310 are used in cooperation to facilitate the buffering of the force generated by vibration. At the same time, when the force is applied to the spring 310, the mounting box 301 consumes the force by contraction or extension.

[0023] Furthermore, the inner wall of the mounting box 301 is provided with a plurality of first fixing grooves 311, and a first polar block 312 is fixedly connected to the inner wall of the first fixing groove 311. The periphery of the mounting box 301 is provided with a second fixing groove 313, and a second polar block 314 is fixedly connected to the inner wall of the second fixing groove 313. By using the plurality of first polar blocks 312 and second polar blocks 314 in cooperation with each other, it is easy to constrain the mounting box 301 and keep the mounting box 301 at the center position of the top surface of the mounting box 301.

[0024] Furthermore, multiple flow holes 315 are provided on the periphery of the main body box 1. The multiple flow holes 315 are matched in size. The multiple flow holes 315 facilitate the airflow inside the main body box 1, thereby maintaining a good heat dissipation effect on the data processor 2.

[0025] Furthermore, a clearance groove 316 is provided on the top surface of the main body box 1, and a baffle plate 317 is provided on the inner wall of the clearance groove 316. The baffle plate 317 facilitates the shielding of the data processor 2, preventing debris from entering the interior of the main body box 1 and affecting the normal use of the data processor 2.

[0026] Furthermore, the dimensions of the multiple first polarity blocks 312 and the second polarity blocks 314 are matched, and the polarity directions of the first polarity blocks 312 and the second polarity blocks 314 are set opposite. By setting the polarity directions of the first polarity blocks 312 and the second polarity blocks 314 opposite, the like poles repel each other, so that the mounting box 301 will not deviate from the center of the main body box 1.

[0027] Working principle: Through the vibration damping and protection component 3, when ground vibration is transmitted to the mounting box 301, the damping block 306 on the bottom of the mounting box 301 shakes and the rotating ball 303 rotates when the mounting box 301 moves, thereby consuming the force generated by the vibration. This keeps the data processor 2 and the mounting box 301 relatively stationary, thus preventing the energy generated by ground vibration from directly acting on the data processor 2 and causing the bolts or clips of the internal components of the data processor 2 to fall off. The sliding seat 309, the fixed column 307 and the spring 310 work together to buffer the force generated by the vibration. At the same time, when the force is applied to the spring 310, the mounting box 301 consumes the force by contracting or extending. The polarity direction of the first polarity block 312 is set opposite to that of the second polarity block 314, so that like poles repel each other and the mounting box 301 does not deviate from the center of the main body box 1.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
