In addition, as an example, as shown in fig. 3-7, this example solves the problem of further self-checking the operation condition of the device.
This device still includes two pressure movable plates 404 of rigid coupling on riser 403, all rotates on every supplementary portion 201 and is connected with swivel mount 301, and equal rigid coupling has second torsional spring 303 between every swivel mount 301 and the supplementary portion 201, and equal rigid coupling has cylinder pole 302 on every swivel mount 301, and two pressure movable plates 404 can contact with two cylinder poles 302 respectively, all is equipped with angle sensor on every supplementary portion 201, and two angle sensors are connected with two swivel mounts 301 respectively.

because the two pressing plates 404 are in a trapezoidal structure, and the surfaces of the two pressing plates 404, which are in contact with the two cylindrical rods 302, are inclined surfaces, when the vertical plate 403 rotates to a left horizontal posture, the inclined surface on the pressing plate 404 on the left side of the vertical plate 403 can gradually press the cylindrical rods 302 on the left swivel base 301, so that the left swivel base 301 overcomes the torsion of the second torsion spring 303 to rotate once, at this time, the angle sensor on the left side can record the angle of rotation once, when the auxiliary portion 201 moves to the next position, and the vertical plate 403 rotates to the left horizontal posture again, the inclined surface on the pressing plate 404 can press the cylindrical rods 302 again, but because the position of the auxiliary portion 201 changes at this time, the contact area between the cylindrical rods 302 and the inclined surface on the swivel column 401 is changed, and further the rotation angle of the cylindrical rods 302 is changed;
that is, the rotation angles of the vertical plate 403 are the same at each time, but the positions of the auxiliary portions 201 are different, so that the pressing plate 404 presses the cylindrical rod 302 to make the rotation angle of the rotary base 301 different, when the auxiliary portion 201 is closer to the center of the valve body 101, the smaller the rotation angle of the rotary base 301 can be pressed, and thus whether the two auxiliary portions 201 normally move can be further determined through the two angle sensors, and further whether the two auxiliary portions 201 normally operate and rotate can be determined through two angle sensors and two displacement sensors of the device, so that when a certain sensor transmits fault information, a worker can roughly determine whether the fault information is error information caused by self fault in the two angle sensors and the two displacement sensors, and the maintenance efficiency is improved.

In addition, as an example, as shown in fig. 2 and 8, the example solves the problem of facilitating timely finding of the frost crack icing condition.
In the device, an arc plate 501 is slidably connected to each auxiliary part 201.
Before the auxiliary part 201 is operated to move each time, the rotary base 301 is firstly pressed to rotate, so that the transmission rod 304 rotates, the rotary transmission rod 304 can press the arc-shaped plate 501 to slide on the auxiliary part 201, if the transmission rod 304 on one of the left side and the right side cannot press the arc-shaped plate 501 to slide at a certain moment, after the vertical plate 403 rotates, the rotary base 301 on the side does not rotate according to a normal angle, the auxiliary part 201 is operated to slide again, if the auxiliary part 201 slides to an overlapped position with the arc-shaped plate 501, the auxiliary part 201 cannot slide, and if the angle sensor and the displacement sensor on the same side cannot obtain signals successively, a certain abnormal bulge is proved to exist on the valve body 101 at the moment, so that the auxiliary part 201 cannot slide normally, namely, the condition that water seeps out and freezes due to frost cracking of the valve body 101 occurs, and the purpose of timely finding of the freezing condition is achieved.
In addition, as an example, as shown in fig. 2 and 8, this example solves the problem of facilitating the sliding of the arc plate 501 for a plurality of operations.
