DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1-Figure 8 When the existing data acquisition device detects the transformer data, it is not convenient to stably connect with the transformer. When the data acquisition device and the screw hole position on the transformer deviate, it is easy to affect the connection between the data acquisition device and the transformer. In order to solve this technical problem, this embodiment discloses the following technical content: a transformer data acquisition device, including an outer shell 1, a heat dissipation dustproof net 2 is installed on the side of the outer shell 1, and a voltage sensor 3 is fixedly connected to the inside of the outer shell 1, a current sensor 4 is arranged on the side of the voltage sensor 3, and a temperature sensor 5 is arranged on the side of the current sensor 4, and a voltage The sensing parts of the sensor 3, the current sensor 4 and the temperature sensor 5 are connected to the collection parts on the transformer, and a display screen 6 is installed on the outer shell 1; an adjustable locking component 7 is installed on the side of the outer shell 1, and the adjustable locking component 7 includes a positioning frame 701, a moving plate 702, a locking bolt 703 and a shock-absorbing gasket 704; the positioning frame 701 is fixedly installed on the outer side of the outer shell 1, and a moving plate 702 is arranged on the inner side of the positioning frame 701, a locking bolt 703 is installed in the middle of the moving plate 702, and a shock-absorbing gasket 704 is installed between the end of the locking bolt 703 and the moving plate 702. A sliding groove for the moving plate 702 to move is opened in the middle of the positioning frame 701, and the outer wall of the moving plate 702 and the inner wall of the sliding groove are in contact with each other, and the moving plate 702 and the positioning frame 701 are in sliding connection.

[0029] When the data acquisition device is needed to collect data from the transformer, the data acquisition device is placed at the desired installation position on the transformer, and then the movable plate 702 is slid on the inner side of the positioning frame 701 to align the screw holes on the movable plate 702 with the screw holes on the transformer.

The data acquisition device is prone to generate more heat due to the operation of internal components when in use. When the internal heat accumulation of the data acquisition device is in an overheated state, it will not only affect its own service life, but also affect the accuracy of the transformer data detection results. In order to solve this technical problem, this embodiment discloses the following technical content: a guide groove 8 is provided on the side of the outer shell 1 facing the transformer, a protective cover 9 is fixedly connected to the top of the inner shell 1, and a through hole 10 is provided at the bottom of the protective cover 9. A self-cleaning toggle component 11 is installed at the upper end of the outer shell 1. The self-cleaning toggle component 11 is used to automatically clean the impurities attached to the surface of the heat dissipation dustproof net 2 when it rains. There are multiple guide grooves 8 evenly distributed on the surface of the outer shell 1, and each guide groove 8 is set to a rectangular structure. The inside of the protective cover 9 is evenly filled with desiccant particles, and the diameter of the desiccant particles is greater than the diameter of the through hole 10 at the bottom of the protective cover 9, and the through hole 10 is evenly distributed on the protective cover 9.

The upper end of the collection box 111 is set as an open structure, and the guide frame 113 at the lower end of the collection box 111 can slide on the outer shell 1. The scraper rod on the cleaning rod 115 fits with the outer surface of the heat dissipation and dustproof net 2, and the length of the cleaning rod 115 is equal to the radius of the heat dissipation and dustproof net 2, and the middle rod body of the cleaning rod 115 can rotate in the middle of the heat dissipation and dustproof net 2.

After the guide frame 113 moves downward, the traction The rope 114 is relaxed, and the cleaning rod 115 is reset and rotated under the action of the vortex spring 116. The reset cleaning rod 115 can effectively clean the impurities attached to the surface of the heat dissipation and dustproof net 2. At the same time, the collecting box 111 can make the clamping column 117 move downward synchronously after moving downward, and the clamping column 117 can make the clamping block 1111 move in the clamping groove 1110 inside the center rod 118 after moving downward. Because the clamping groove 1110 is set in a spiral shape, the clamping block 1111 can make the center rod 118 rotate after moving. Through the rotation of the center rod 118, the flipping rod 119 can be used to effectively flip the desiccant particles inside the protective cover 9, so that the desiccant particles can absorb moisture evenly.
