DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0026] Referring to Figures 1-7 A single-shaft electric actuator comprises a conveying pipeline structure 1 and an electric actuator body 2. The electric actuator body 2 is fixedly installed with a bottom plate 12. The two end sidewalls of the bottom plate 12 are fixedly installed with sliding blocks 13. A protection mechanism is arranged between the two sliding blocks 13. The protection mechanism comprises a blocking frame 3 which is slidingly connected between the two sliding blocks 13. The sidewall of the blocking frame 3 is provided with an observation window. Through the arrangement of the observation window on the blocking frame 3, it is convenient for the operator to read the data displayed on the display of the electric actuator body 2. The sidewalls of the two sliding blocks 13 are provided with clamping grooves 14. The two end sidewalls of the blocking frame 3 are penetrated by threaded rods 9 which are connected by threads. One end of the threaded rod 9 which is located outside the blocking frame 3 is fixedly installed with a screw cap. The end portions of the two threaded rods 9 extend into the opposite clamping grooves 14 and abut against the inner sidewalls thereof. The top of the blocking frame 3 is rotatably connected with a cover plate 6.

[0027] Through the arrangement of the protection mechanism, after the electric actuator body 2 is installed on the conveying pipeline structure 1, the entire electric actuator body 2 can be shielded and protected, so as to avoid the damage of the electric actuator body 2 caused by the collision of external objects.

[0028] The sidewall of the blocking frame 3 is fixedly installed with two first mounting plates 7. The top of each of the two first mounting plates 7 is fixedly installed with a first magnetic block 10.

[0029] The sidewall of the cover plate 6 is fixedly installed with two second mounting plates 8. The bottom of each of the two second mounting plates 8 is fixedly installed with a second magnetic block 11. The bottom of each of the two second magnetic blocks 11 abuts against the top of the opposite first magnetic block 10 and the magnetic poles thereof are opposite.

[0030] Through the arrangement of the first mounting plate 7, the second mounting plate 8, the first magnetic block 10 and the second magnetic block 11, the stability of the cover plate 6 when closed can be ensured.

[0031] The bottom of the bottom plate 12 is fixedly installed with two connecting rods 4. The bottom end of each of the two connecting rods 4 is fixedly installed with an arc-shaped support plate 5. The inner wall of the arc-shaped support plate 5 is fixedly installed with a rubber pad. The bottom of the rubber pad abuts against the top of the pipeline of the conveying pipeline structure 1.

[0032] Through the arrangement of the connecting rod 4 and the arc-shaped support plate 5, when the electric actuator body 2 is installed on the conveying pipeline structure 1, it can support the electric actuator body 2 placed on the conveying pipeline structure 1, ensure the stable placement of the electric actuator body 2, and thus facilitate the operator to use bolts to fix the conveying pipeline structure 1 and the electric actuator body 2 together.

[0033] The functional principle of this utility model can be explained through the following operation modes:

[0034] When the electric actuator body 2 needs to be installed on the conveying pipeline structure 1, first, the operator places the electric actuator body 2 on the conveying pipeline structure 1 so that the output end of the electric actuator body 2 at the bottom is aligned with the valve on the conveying pipeline structure 1, so that the output end of the electric actuator body 2 is clamped on the valve on the conveying pipeline structure 1. At this time, the two arc-shaped support plates 5 are clamped on the pipes at both ends of the conveying pipeline structure 1. Due to the support of the arc-shaped support plates 5, the electric actuator body 2 can be placed stably. At this time, the operator uses bolts to fix the conveying pipeline structure 1 and the electric actuator body 2.

[0035] When the operator needs to inspect the electric actuator body 2, first, the operator rotates the cover plate 6 so that the cover plate 6 is disengaged from the blockage of the baffle frame 3, and then rotates the two threaded rods 9 so that the two threaded rods 9 are disengaged from the corresponding slots 14. At this time, the baffle frame 3 slides downward under the action of gravity, and the baffle frame 3 is disengaged from the obstruction of the electric actuator body 2, and the operator can inspect the electric actuator body 2.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
