[0002] An electric actuator is an automated device that controls mechanical motion through electrical signals. It is mainly used to convert electrical energy into mechanical energy to drive devices such as valves and gears, and is widely used in the field of industrial automation control.

[0003] Existing valves are usually closed or opened by electric actuators. However, after a power outage, the valves need to be manually closed or opened by staff. This means that the valves cannot be opened or closed immediately after the power outage, which can easily cause safety hazards.

[0004] Therefore, an electric actuator with automatic valve reset function is needed to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the above-mentioned electric actuator with automatic valve reset function, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide an electric actuator with an automatic valve reset function, which solves the problem that after a power outage, the valve cannot be opened or closed immediately by the operator, which can easily cause safety hazards.

[0008] To solve the above technical problems, this utility model provides the following technical solution: an electric actuator with an automatic reset valve function, comprising: a housing, a motor fixed on the housing, a rotating shaft extending into the housing fixed at the output shaft end of the motor, a rotating column extending out of the housing rotatably connected inside the housing, a valve plate fixed at the lower end of the rotating column, a short shaft rotatably connected inside the housing, and a horizontal column rotatably connected inside the housing.

[0009] The reset mechanism is used to reset the valve plate on the rotating column by driving the rotating shaft after power failure.

[0010] The fixing component is used to fix the valve plate after the rotating column drives it to reset after the power is cut off.

[0011] As a preferred embodiment of the electric actuator with automatic reset valve function described in this utility model, a worm gear is fixed on the rotating shaft, and a worm wheel is fixed on the rotating column, with the worm wheel meshing with the worm gear.

[0012] As a preferred embodiment of the electric actuator with automatic reset valve function described in this utility model, wherein: an electromagnetic block one is fixed at both the left and right ends inside the housing, an electromagnetic block two is slidably connected to the cross column, and the electromagnetic block two is fixedly connected to the fixing component.

[0013] As a preferred embodiment of the electric actuator with automatic reset valve function described in this utility model, the fixing component includes two slip rings slidably connected to a horizontal column, a connecting rod fixed on the slip ring, the connecting rod being fixedly connected to an electromagnetic block, a fixing column fixed on the connecting rod, the other end of the fixing column being arc-shaped, a through hole being opened on the short shaft, and the fixing column being sleeved into the through hole.

[0014] As a preferred embodiment of the electric actuator with automatic reset valve function described in this utility model, springs are fixed on both the left and right sides inside the housing, and the other end of the spring is fixedly connected to the slip ring.

[0015] As a preferred embodiment of the electric actuator with automatic reset valve function described in this utility model, a torsion spring is fixed inside the housing, a connecting block is fixed on the short shaft, and the connecting block is fixedly connected to the upper end of the torsion spring.

[0016] As a preferred embodiment of the electric actuator with automatic reset valve function described in this utility model, the reset mechanism includes a first bevel gear fixed on a short shaft, a second bevel gear fixed on the rotating shaft, and the first bevel gear meshing with the second bevel gear.

[0017] As a preferred embodiment of the electric actuator with automatic reset valve function described in this utility model, a gear is fixed on the short shaft, a rack is fixed on the connecting rod, and the rack meshes with the gear.

[0018] The beneficial effects of this utility model are as follows: When the motor is started, the rotating shaft rotates. The worm gear on the rotating shaft drives the worm wheel to rotate the rotating column, which in turn drives the valve plate to rotate, thus opening or closing the valve. At the same time, the rotating shaft drives the short shaft to rotate through bevel gear one and bevel gear two. The torsion spring is compressed in reverse. When the power is cut off, the electromagnetic blocks one and two are no longer attracted after being de-energized. The spring force causes the two slip rings to move in the corresponding directions. At the same time, the rack moves. After the rack moves to mesh with the gear, it pushes the gear to drive the short shaft to rotate. The spring force of the torsion spring causes the short shaft to reset. The rotating shaft is reset through bevel gear one and bevel gear two. Finally, the valve plate on the rotating column is reset. The fixing post on the slip ring is inserted into the through hole to fix the short shaft and fix its reset position to prevent loosening.

[0028] Example 1

[0029] Reference Figures 1-2 This is the first embodiment of the present invention. This embodiment provides an electric actuator with an automatic reset valve function, which can achieve the effect of closing or opening the valve immediately after power failure. It includes: a housing 100, a motor 101 fixed on the housing 100, a rotating shaft 102 extending into the housing 100 fixed at the output shaft end of the motor 101, a rotating column 103 extending out of the housing 100 rotatably connected inside the housing 100, a valve plate 104 fixed at the lower end of the rotating column 103, a short shaft 105 rotatably connected inside the housing 100, and a horizontal column 106 rotatably connected inside the housing 100.

[0030] The reset mechanism 200 is used to reset the valve plate 104 on the rotating column 103 by driving the rotating shaft 102 after power failure.

[0031] The fixing component 300 is used to fix the valve plate 104 after the rotating column 103 drives it to reset after the power is cut off.

[0032] When in use, after power failure, the reset mechanism 200 causes the rotating shaft 102 to rotate, which in turn drives the valve plate 104 on the rotating column 103 to rotate, thereby closing or opening the valve. The fixing component 300 fixes the rotating column 103 to its position after rotation to prevent loosening.

[0033] Example 2

[0034] Reference Figures 2-3This is the second embodiment of the present invention. Unlike the previous embodiment, embodiment 2 is an optimization of embodiment 1.

[0035] Among them, a worm 107 is fixed on the rotating shaft 102, and a worm wheel 108 is fixed on the rotating column 103. The worm wheel 108 meshes with the worm 107.

[0036] Electromagnetic blocks 109 are fixed at both ends of the outer shell 100, and electromagnetic blocks 110 are slidably connected to the horizontal column 106. Electromagnetic blocks 110 are fixedly connected to the fixing component 300.

[0037] The fixing component 300 includes two sliding rings 301 that are slidably connected to the horizontal column 106. A connecting rod 302 is fixed on the sliding ring 301. The connecting rod 302 is fixedly connected to the electromagnetic block 110. A fixing post 303 is fixed on the connecting rod 302. The other end of the fixing post 303 is arc-shaped. A through hole 304 is opened on the short shaft 105. The fixing post 303 is sleeved into the through hole 304.

[0038] Springs 111 are fixed on both the left and right sides inside the outer casing 100, and the other end of the springs 111 is fixedly connected to the slip ring 301.

[0039] The outer casing 100 has a torsion spring 112 fixed inside, and a connecting block 113 is fixed on the short shaft 105. The connecting block 113 is fixedly connected to the upper end of the torsion spring 112.

[0040] The reset mechanism 200 includes a first bevel gear 201 fixed on a short shaft 105, and a second bevel gear 202 fixed on a rotating shaft 102. The first bevel gear 201 meshes with the second bevel gear 202.

[0041] Among them, a gear 114 is fixed on the short shaft 105, and a rack 115 is fixed on the connecting rod 302, with the rack 115 meshing with the gear 114.

[0042] In operation, the motor 101 is started, and the shaft 102 rotates. The worm gear 107 on the shaft 102 drives the worm wheel 108 to rotate the rotating column 103. The rotating column 103 drives the valve plate 104 to rotate, thus opening or closing the valve. Simultaneously, the shaft 102 drives the short shaft 105 to rotate through bevel gear 1 201 and bevel gear 202. The torsion spring 112 is compressed in reverse. When the power is off, the electromagnetic blocks 1 109 and 110 are no longer attracted to each other, and the spring force of the spring 111 causes the two slip rings 301 to move towards each other. The rack moves in the corresponding direction, and at the same time, the rack 115 moves. After the rack 115 moves and meshes with the gear 114, it pushes the gear 114 to drive the short shaft 105 to rotate. The spring force of the torsion spring 112 is applied to reset the short shaft 105. The rotating shaft 102 is reset through the first bevel gear 201 and the second bevel gear 202. Finally, the valve plate 104 on the rotating column 103 is reset. The fixing post 303 on the slip ring 301 is inserted into the through hole 304 to fix the short shaft 105 and fix its reset position to prevent loosening.
