Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specifically, the clamping plate 14 is made of elastic material, such as rubber, which can prevent the current and voltage transmitter from being damaged. The electric push rod 7 pushes the connecting plate 11 down, so that the second rotating plate 17 and the third rotating plate 18 can rotate slightly. Because the normal length of the first rotating plate 16 and the third rotating plate 18 becomes longer, the lifting plate 13 and the clamping plate 14 can be lowered, thereby fixing the current and voltage transmitter.

[0025] Reference Figure 2 and Figure 4 The cleaning component includes a movable plate 22 and a brush 23. The top surface of the casing body 1 is fixedly connected to the motor 10.

This setting can clean the dust net 20.

[0033] The collecting cabinet 8 is arranged below the empty slot 24 , and the length of the collecting cabinet 8 is greater than the length of the empty slot 24 .

[0034] Specifically, this arrangement prevents dust from not completely falling into the collection cabinet 8 .

[0036] Specifically, the housing body 1 and the fixing plate 3 provide an installation position for the screw rod 21 .

[0037] Reference Figure 1 and Figure 2 A plurality of heat dissipation holes 9 are provided on one end surface of the casing body 1 , and four second support frames 5 are fixedly connected to the bottom surface of the casing body 1 .

[0038] Specifically, the heat dissipation holes 9 can provide a channel for heat exchange between the inside of the shell and the outside.

[0039] Working principle: Start the electric push rod 7, which pushes the connecting plate 11 down, so that the first rotating plate 16, the second rotating plate 17 and the third rotating plate 18 can be rotated, so that the normal length of the first rotating plate 16 and the third rotating plate 18 becomes longer, and the lifting plate 13 and the clamping plate 14 can be lowered, so as to fix the transmitter; dust enters the inside of the casing body 1 from the heat dissipation hole 9, and the dustproof net 20 can prevent dust from entering the inside of the transmitter, and the motor 10 is started, so that the screw rod 21 can be rotated, and the movable plate 22 can be driven to move, and the dustproof net 20 can be cleaned, and the dust can fall into the collection cabinet 8.
