[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A data acquisition device for ultra-high voltage multiple physical quantities on the power grid side, comprising:

[0007] A mounting frame, wherein the top and bottom of the mounting frame are both hinged with a frame through hinges, four sides of the mounting frame are detachably provided with four spaced grips, a monitoring host is detachably provided inside the mounting frame, a total of six cameras are provided on the front, rear and bottom of the monitoring host, and an acceleration sensor, a gyroscope sensor, a temperature and humidity sensor, an air pressure sensor and an RTK positioning module are provided inside the monitoring host;

[0008] Energy acquisition grippers, four of which are provided, and all of which can be unfolded, engaged and locked by bolts, and two temperature sensors and two current sensors are provided inside the two sides of each of the energy acquisition grippers;

[0011] In a possible design, a buckle is fixedly provided on one side of the two frames, and buckle grooves are provided on the top and bottom of the mounting frame. The buckle is adapted to the buckle groove and can be disengaged.

[0012] In a possible design, the top of the energy extraction gripper is electrically connected to a connecting wire, one end of the connecting wire is electrically connected to a plug, and the outer cover of the connecting wire is provided with a sponge cover.

[0013] In a possible design, a sensor is provided on the spacer gripping claw, and the spacer gripping claw can be unfolded and engaged and locked by a bolt.

[0014] In a possible design, sockets are symmetrically provided on both sides of the monitoring host, through holes are symmetrically provided on both sides of the mounting frame, and the positions of the through holes correspond to the sockets. The sockets and the plug of the energy extraction claw can be detached from each other, and the sponge cover can be removed and inserted into the through hole.

[0015] In the present application, when starting to use, first install the mounting frame with four spaced grips through bolts, and install the four spaced grips on the four sides of the mounting frame respectively.

At this time, the installation of the data acquisition device is completed. After the device has been working for a period of time, the motor starts, and the output shaft of the motor drives the reciprocating screw to rotate. While the reciprocating screw rotates, it drives the moving plate to move on the two guide rods, and while the moving plate moves, the sponge at the bottom of the moving plate wipes the camera.

[0016] The utility model has the following beneficial effects:

[0017] In the utility model, by setting the cleaning component, when the motor is started, the reciprocating screw rod is driven to rotate, and then the moving plate is driven to slide back and forth on the guide rod, so that the sponge can automatically wipe the camera, so that the dirt and water vapor adsorbed on the camera can be regularly cleaned and removed, ensuring that the camera can capture clear image information, thereby improving the quality of power grid monitoring;
