A supporting cross plate 2 is connected between the two sides of the inner bottom end of the electrostatic monitor body 1, and a driving motor 3 is installed at the bottom of the supporting cross plate 2. The output shaft of the driving motor 3 is connected to the fan blade 4. The isolation mesh cover 5 is a "U"-shaped structure. The outer surface of the isolation mesh cover 5 and the inner surface of the base 7 are tightly fitted. Four fixing blocks 6 are provided. The bottom of the electrostatic monitor body 1 is provided with an isolation mesh cover 5, and fixing blocks 6 are fixed on both sides of the bottom of the isolation mesh cover 5. The base 7 is provided on the outside of the isolation mesh cover 5.

[0022] The specific operation is as follows: when the isolation mesh cover 5 extends outward from the base 7, the electrostatic monitor body 1 can be adjusted to a suspended state, thereby increasing the heat dissipation area. The output shaft of the drive motor 3 drives the fan blades 4 to rotate, accelerating the air flow rate inside the electrostatic monitor body 1, so that the heat dissipation effect inside the electrostatic monitor body 1 is significant.

[0023] like Figure 1 and Figure 2As shown, a protective assembly 8 is installed at the inner bottom end of the base 7, and the protective assembly 8 includes a support 801, a two-way screw rod 1 802, a driven gear 803, a toothed belt 804, a driving gear 805, a two-way screw rod 2 806, a bevel gear 1 807, a bevel gear 2 808, a transmission shaft 809, a hand crank 810, a screw nut 811, a moving block 812 and a connecting rod 813. A two-way screw rod 1 802 is connected between the two supports 801, and the outer sleeve of the two-way screw rod 1 802 is provided with a driven gear 803, the outer portion of the driven gear 803 is connected to the driving gear 805 through the toothed belt 804, and the middle part of the driving gear 805 is penetrated by a two-way screw rod 2 806, the outer sleeve of the two-way screw rod 2 806 is provided with a bevel gear 1 807, and the outer connection of the bevel gear 1 807 There is a bevel gear 2 808, a transmission shaft 809 is passed through the middle of the bevel gear 2 808, and the rear end of the transmission shaft 809 is connected to a hand crank 810, the outside of the two-way screw rod 1 802 and the two-way screw rod 2 806 are connected to the screw nut 811, and the side of the screw nut 811 is fixed with a moving block 812, and the middle part of the moving block 812 is connected to a connecting rod 813 through a rotating shaft, the two-way screw rod 1 802 and the two-way screw rod 2 806 are parallel to each other, and the support 801 and the two-way screw rod 1 802 are perpendicular to each other, the two-way screw rod 2 806 and the transmission shaft 809 are perpendicular to each other, and the transmission shaft 809 passes through the bearing at the rear end opening of the base 7, the end of the connecting rod 813 away from the moving block 812 is rotatably connected to the fixed block 6, and the fixed block 6 and the moving block 812 are set in the same number.

[0024] The specific operation is as follows: the toothed belt 804 is driven by the external active gear 805 of the bidirectional screw rod 2 806 to rotate the driven gear 803, so that the screw nut 811 can be horizontally displaced relative to the external sides of the bidirectional screw rod 1 802 and the bidirectional screw rod 2 806, thereby changing the supporting angle of the connecting rod 813 on the fixed block 6 and causing the isolation mesh cover 5 to drop into the base 7, thereby realizing dust-proof protection for the electrostatic monitor body 1 when it is not in operation.

[0025] In summary, when the electrostatic voltage monitoring device that is easy to protect is used, first, the hand crank 810 is shaken in the working state, and the hand crank 810 drives the transmission shaft 809 and the bevel gear 2 808 to rotate, and the bevel gear 2 808 drives the bevel gear 1 807 to drive the bidirectional screw rod 2 806 to rotate, and the driving gear 805 outside the bidirectional screw rod 2 806 drives the toothed belt 804 to drive the driven gear 803 to rotate, so that the screw nut 811 is respectively horizontally displaced in opposite directions with respect to the outside of the bidirectional screw rod 1 802 and the bidirectional screw rod 2 806, and the moving block 812 changes the angle of the connecting rod 813 during the movement of the screw nut 811, causing the isolation mesh cover 5 to extend outward from the base 7, thereby adjusting the electrostatic monitor body 1 to a suspended state, and the isolation mesh cover 5 is enclosed between the electrostatic monitor body 1 and the base 7, thereby increasing the heat dissipation area while preventing foreign matter from entering the electrostatic monitor body 1;

[0026] As the temperature inside the electrostatic monitor body 1 rises, the drive motor 3 at the bottom of the support cross plate 2 will drive the fan blades 4 on the output shaft to rotate, pushing the surrounding air through the fan blades 4 to make it flow, promoting the heat inside the electrostatic monitor body 1 to dissipate outwards, making the heat dissipation effect significant, which is conducive to stabilizing the monitoring performance of the electrostatic monitor body 1;

[0027] When the monitoring is finished, the hand crank 810 is shaken again, so that the screw nut 811 makes a relative horizontal displacement with respect to the outside of the bidirectional screw rod 1 802 and the bidirectional screw rod 2 806, thereby changing the support angle of the connecting rod 813 on the fixed block 6, and the isolation mesh cover 5 is retracted into the base 7, so that the electrostatic monitor body 1 falls on the base 7, thereby providing dust protection for the electrostatic monitor body 1 to prevent the accumulation of dust from affecting its normal operation.

[0028] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
