[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] Embodiment 1:

[0021] Please refer to Figure 1-4 A high-precision double-sealed intelligent electric actuator comprises an electric actuator body 1, a door cover 2 is arranged on the upper surface of the electric actuator body 1, rotating columns 3 are movably installed on the left and right sides of the door cover 2, a first limit block 4 is fixedly installed on the lower end of the rotating column 3, a torsion spring 5 is sleeved on the outer surface of the rotating column 3, a groove 6 is arranged on the upper surface of the rotating column 3, through holes 7 are arranged on the left and right surfaces of the electric actuator body 1, second limit blocks 4 are fixedly installed on the left and right surfaces of the electric actuator body 1, and a limit groove 9 is provided on the inner wall of the second limit block 4.

[0022] Specifically: During the use of the utility model, the door cover 2 is located on the upper surface of the electric actuator body 1. When the electric actuator body 1 needs to be repaired, the tool is inserted into the groove 6, and then the tool is rotated. The tool rotates, thereby driving the groove 6 and the rotating column 3 to rotate. When the rotating column 3 rotates, the first limit block 4 is driven to rotate, and the first limit block 4 gradually moves away from the inside of the limit groove 9 until the first limit block 4 rotates 90° and the first limit block 4 is completely away from the inside of the limit groove 9. At this time, the door cover 2 is pulled upward, and the door cover 2 gradually moves away from the electric actuator body 1, and the torsion spring 5 is in a twisted state until the door cover 2 is completely taken down. At this time, the twisting force is released and the torsion spring 5 rebounds. When installation is required, the rotating column 3 is twisted in advance by a tool. After the rotating column 3 is twisted 90° to a longitudinal state, the door cover 2 is directly placed on the upper surface of the electric actuator body 1. After the lower surface of the door cover 2 is completely fitted with the upper surface of the electric actuator body 1, the rotating column 3 is released at this time. The torsion spring 5 drives the first limit block 4 to enter the inside of the limit groove 9 due to its own resilience, thereby completing the installation of the door cover 2.

[0023] In this embodiment: a mounting plate 15 is provided on the front surface of the electric actuator body 1 .

[0024] Specifically: the mounting plate 15 is an existing structure, which can achieve the effect of mounting the electric actuator with other structures.

[0025] In this embodiment: the groove 6 is one of a cross groove, a straight groove, a plum blossom groove, a square groove 6, and a hexagonal groove 6. The upper end of the torsion spring 5 is fixedly connected to the lower inner wall of the door cover 2, and the lower end of the torsion spring 5 is fixedly connected to the upper surface of the first limit block 4. The limit groove 9 matches the first limit block 4 and the through hole 7.

[0026] Specifically: the rotation of the rotating column 3 is completed through the groove 6, thereby driving the first limit block 4 to rotate, and the first limit block 4 is limited by the resilience of the torsion spring 5 itself, thereby achieving the effect of convenient installation.

[0027] In this embodiment: the surface of the mounting plate 15 is provided with mounting holes.

[0028] Working principle: The utility model realizes convenient installation of the door cover 2 by rotating the rotating column 3. When it is in an idle state, the first limit block 4 is designed to be horizontal. When it is twisted, after twisting it 90°, the first limit block 4 is in a longitudinal state, and it can be installed and disassembled. Compared with the related technology, the high-precision double-sealed intelligent electric actuator provided by the utility model has the following beneficial effects: the design can realize convenient installation and disassembly of the electric actuator as a whole, so as to facilitate the workers to inspect and repair the inside of the electric actuator later, save time, and improve the practicality of the device.

[0029] Embodiment 2:

[0030] Please refer to Figure 1-4 A power supply 10 is fixedly installed on the rear surface of the electric actuator body 1, a backup power supply 11 is fixedly installed on the rear surface of the electric actuator body 1, a connecting wire 12 is fixedly installed on the lower surface of the power supply 10, a switch button 13 is provided on the rear surface of the electric actuator body 1, and a current sensor 14 is fixedly installed on the rear surface of the electric actuator body 1.

[0031] Specifically: when the electric actuator is in use and the entire device is powered, the power supply 10 will charge the backup power supply 11 through the connecting wire 12, so that it is in a fully charged state. The current sensor 14 will detect the power supply 10 in real time. When the power supply 10 is damaged, the electric actuator loses the power supply from the power supply 10 and stops working directly. At this time, the backup power supply 11 directly supplies power to the electric actuator, thereby taking over the power supply 10 to power it and helping the electric actuator to continue working. When the power supply 10 is not damaged and the backup power supply 11 is needed, the switch button 13 is directly pressed. After pressing, the power supply 10 is turned off and the backup power supply 11 is turned on, thereby powering the device body.

[0032] In this embodiment: the lower end of the connecting wire 12 is fixedly connected to the upper end of the backup power supply 11, the power supply 10 and the backup power supply 11 are electrically connected through the connecting wire 12, the switch button 13 is electrically connected to the backup power supply 11, the current sensor 14 is electrically connected to the power supply 10, and the power supply 10 and the backup power supply 11 are both electrically connected to the electric actuator body 1.

[0033] Specifically: by switching between the power supply 10 and the backup power supply 11, continuous power supply is achieved. In non-emergency situations, the main power supply 10 is in working condition, and the backup power supply 11 charges the battery through the charging device. In emergency situations, the dual power supply 10 switching switch switches the load from the main power supply 10 to the backup power supply 11 in a very short time at the millisecond level. At this time, the main power supply 10 is in the off state, and the backup power supply 11 provides power to the load.

[0034] Working principle: The utility model can power the electric actuator in different ways by switching between the backup power supply 11 and the power supply 10. It is worth mentioning that the electric actuator body 1 contains a valve. When the electric actuator is powered off during operation, the valve can only be in its original position. At this time, the valve is in a dangerous position. Due to the power off, the valve cannot return to the fail-safe position, so it needs to be powered to return to the fail-safe position. Compared with the related technology, the high-precision double-sealed intelligent electric actuator provided by the utility model has the following beneficial effects: This design can achieve the effect of powering the electric actuator in multiple ways, thereby ensuring its stable operation and improving the practicability of the device.

[0035] The conversion of the backup power supply 11 and the power supply 10 is an existing structure, and the control circuit can be realized by simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0036] The above-mentioned equipment is used in different ways for each device. It is selected and used according to actual conditions, and various parameters are referred to, in accordance with the functions of the equipment used and the effects achieved.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
