[0051] In example two, on the basis of example one, referring to Figures 1 to 9 As shown, the staff needs to install a circuit board with a control module in the inside of the stabilizing shell 2. The model of the circuit board is selected from the commonly used models of the electric mechanism 3 in the prior art. In addition, a controller in the prior art needs to be arranged and electrically connected with the electric mechanism 3 and the circuit board.

[0052] In example three, on the basis of example one, referring to Figures 1 to 9 As shown, the bottom position of the protective cover 1 and the first positioning shell 302 is respectively provided with a set of stabilizing plates with mounting holes on both sides. The stabilizing plates are installed after the position of the mounting bolt is installed.

When the electric mechanism 3 is used outdoors, the protective cover 1 is assembled. When the electric mechanism 3 is used indoors at room temperature, the protective cover 1 is removed.

[0053] The working principle of the embodiment is as follows:

[0054] The initial installation and preparation steps of the whole, the workers determine whether to install the protective cover 1 according to the use environment, if used outdoors, the two parts of the protective cover 1 are stably assembled through bolts, ensure that it is installed firmly and sealed well, choose the protective cover 1 material with good light reflection effect to reduce the influence of high temperature caused by sunlight, at the same time, confirm that the shaking sensor in the protective cover 1 has been correctly installed in the positioning frame, and the electrical connection with the controller is completed, the preliminary assembly of each part of the electric mechanism 3 is carried out, the drive shaft of the electric motor 301 is connected with the threaded rod 303 through the reduction gear set, ensure that the connection is stable and the transmission is smooth, the positioning strip inside the first positioning shell 302 passes through the limiting groove of the threaded connecting seat 305, the threaded hole of the threaded connecting seat 305 is aligned with the threaded rod 303 and is screwed, the preliminary connection is realized, the sliding groove of the positioning ring of the push rod 304 is matched with the positioning strip of the first positioning shell 302, then the push rod 304 and the threaded connecting seat 305 are stably assembled through bolts, at the same time, the snap spring 306 is installed in the positioning groove of the threaded connecting seat 305, preventing the bolt from loosening, the sealing ring 307 is installed in the positioning groove of the first positioning shell 302, so that the push rod 304 passes through the sealing ring 307, ensuring good sealing;

[0055] The worker inserts the plug 4 on one side of the electric motor 301 into the power socket, and stabilizes it through the cooperation of the second positioning shell 5 and the stabilizing rod 501. The stabilizing rod 501 automatically extends into the stabilizing groove on one side of the plug 4 under the action of the supporting spring, ensuring that the plug 4 will not loosen. If the plug 4 needs to be removed, the control block of the stabilizing rod 501 can be manually pushed to make the stabilizing rod 501 move reversely and separate from the stabilizing groove, so that the plug 4 can be pulled out.

[0056] The electric mechanism 3 control and operation steps, when the electric mechanism 3 needs to be automatically operated, the running parameters of the electric motor 301 are set through the controller, such as speed and direction, the controller automatically controls the electric motor 301 to drive the reduction gear set, and then drives the threaded rod 303 to rotate. Due to the threaded connection between the threaded connecting seat 305 and the threaded rod 303 and the cooperation between the positioning strip and the limiting groove, the threaded connecting seat 305 will move transversely along the positioning groove, thereby driving the push rod 304 to realize extension and retraction movement, completing the pushing or pulling operation of the object;

[0057] During the operation of the electric mechanism 3, if jamming or shaking occurs, the shaking sensor will immediately transmit a signal to the controller. At the same time, the worker can use a hexagonal wrench to insert into the hexagonal groove of the control shaft 6 and manually twist the control shaft 6 to rotate. Since the drive shaft of the electric motor 301 and the control shaft 6 are meshed through the drive bevel gear and the driven bevel gear, the rotation of the control shaft 6 can realize manual control of the electric mechanism 3. In emergency situations, the object can be hard driven to restore normal operation or adjust to a safe position;

[0058] Special case handling and maintenance steps of the electric mechanism 3, if internal repair and maintenance of the electric mechanism 3 is needed during use, the protective cover 1 (if installed) can be removed first, when the protective cover 1 is removed, the bolts connecting the two parts of the protective cover 1 can be unscrewed, for the circuit board with control module installed inside the stable shell 2 (if installed), circuit inspection or parameter adjustment can be performed according to the needs, but the operation needs to be performed under the condition of power off, and the operation needs to be performed by professional personnel according to the relevant electrical safety specifications.
