[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See also Figures 1 to 6 , the invention provides a technical solution:

[0025] The manual valve electric operating device of this embodiment includes a small diesel generator set 1 for providing power, an electric motor 2 powered by the small diesel generator set 1 to provide operating power, a planetary gear transmission module 3, an adjustable fixed plate 5, and a control device; an adjustable base 21 is provided at the bottom of the electric motor 2, the output shaft of the electric motor 2 is connected to the sun gear 31 of the planetary gear transmission module 3, the ring gear 33 of the planetary gear transmission module 3 is meshed with the first planetary gear 32 and fixed to the adjustable base 21, the first planet carrier 34 of the planetary gear transmission module 3 is connected to the adjustable fixed plate 5, and the adjustable fixed plate 5 is detachably mounted on the manual operating door wheel of the valve for operating the valve switch; the control device is used to start and stop the small diesel generator set 1 and the electric motor 2;

[0026] The general working process is as follows: start the small diesel generator set 1 to supply power, drive the motor 2 to drive the sun gear 31 to rotate, and at the same time the first planetary gear 32 revolves around the sun gear 31, and then the output of the first planetary carrier 34 drives the adjustable fixed disk 5 to rotate the valve handwheel; when the valve reaches the fully open / fully closed position, the control device automatically cuts off the power supply of the motor 2 to prevent overload damage.

[0027] The adjustable fixed plate 5 includes a base plate 51, which is coaxially fixed to the first planetary carrier 34. A plurality of radial slide rails 52 are provided on the surface of the base plate 51. A slider 53 slides in each radial slide rail 52. A vertical column 54 is welded to the end face of the slider 53. A driving arm 55 is hinged at the other end of the vertical column 54. A screw 56 rotates in the radial slide rail 52, and the slider 53 is threadedly connected to the screw 56. By rotating the screw 56, the slider 53 moves along the radial slide rail 52, and then the vertical column 54 drives the driving arm 55 to extend and retract radially. By adjusting each driving arm 55 to the gap between the valve handwheel spokes, the clamping claw 58 engages the spokes, thereby achieving rapid adaptation of valves of different sizes.

[0028] Since field valves are often stuck due to rust, the instantaneous torque can reach several times the normal value, and the traditional rigid transmission is prone to cause the motor to burn out or the gear to break; therefore, the device also includes a torque release mechanism, which includes a disc spring group 6 coaxially sleeved on the motor main shaft 22, and the disc spring group 6 is located between the planetary gear transmission module 3 and the end cover of the motor 2; an electromagnetic locking pin 61 is radially sliding inside the sun gear 31, and the sun gear 31 is fixedly connected to the motor main shaft 22 through the electromagnetic locking pin 61, and an electromagnet 6 is provided on the sun gear 31. 3. The magnetic poles of the electromagnetic locking pin 61 and the electromagnet 63 are opposite. A pressure sensor is provided on the disc spring assembly 6. The pressure sensor is connected to the control system via a signal line, and the control system starts and stops the electromagnet 63. When the valve is stuck, the torque is greater than the set threshold, causing the disc spring assembly 6 to compress and trigger the pressure sensor. Then, the control system cuts off the current to the electromagnet 63. The electromagnetic locking pin 61 is disengaged from the motor main shaft 22 under the action of centrifugal force, and the sun gear 31 idles to protect the transmission system. After the fault is eliminated, the electromagnetic locking pin 61 is restarted, and the locking pin resets and re-engages.

[0029] In order to solve the problem of equipment deflection caused by the tilt and unevenness of the valve installation surface in complex outdoor terrain, a floating compensation mechanism is also included. The floating compensation mechanism includes an axial disc spring group 35 and a radial buffer spring group 36. The sun gear 31 is connected to the motor shaft 22 through a spline sleeve. The axial disc spring group 35 is axially arranged between the spline sleeve and the motor shaft 22, so that the sun gear 31 can float in the axial direction; the output end of the first planetary carrier 34 is connected to the adjustable fixed plate 5 through a cross universal joint, and the radial buffer spring group 36 is arranged between the gear ring 33 and the adjustable base 21; a spherical bearing is provided between the base plate 51 and the cross universal joint. , which is used to enable the fixed plate 5 to tilt adaptively; when the valve mounting surface is tilted, the impact is reduced through three aspects, specifically: axial floating: the sun gear 31 compresses the axial disc spring group 35 to prevent gear engagement; radial buffering: the ring gear 33 compresses the radial buffer spring group 36 to absorb eccentric load vibration; angle adaptation: the spherical bearing allows the inclination angle of the fixed plate 5 to be adjusted; it is worth mentioning that both the axial disc spring group 35 and the radial buffer spring group 36 can adopt butterfly springs and other springs that can withstand higher loads, that is, a greater external force is required during compression to achieve the deformation effect, so as to avoid the self-deflection problem that may occur during normal operation.

[0030] A synchronous locking mechanism is also provided between the adjustable fixed disk 5 and the planetary gear transmission module 3. The synchronous locking mechanism includes a synchronous drive ring 7 and a planetary locking wheel set. The inner circumferential surface of the synchronous drive ring 7 includes a smooth surface and an inner gear ring 71. An annular groove 57 is provided on the outer circumferential surface of the base disk 51. The synchronous drive ring 7 is rotatably sleeved on the outer circumferential surface of the base disk 51 through the smooth surface. A retaining spring is clamped in the annular groove 57 to limit the axial displacement of the synchronous drive ring 7; the planetary locking wheel set includes a locking sun gear 81 coaxially fixed to the output end of the first planetary carrier 34, and the locking sun gear 81 simultaneously engages with three locking planetary gears 82; a gear head 561 is provided at the end of the screw 56, and each locking planetary gear 82 engages with the inner gear ring 71 of the synchronous drive ring 7; the inner gear ring 71 of the synchronous drive ring 7 engages with the gear head 561.

[0031] This solution uses a planetary locking wheel set and a planetary gear transmission module 3, both of which are planetary gears, but their functions are different. Among them, the planetary gear transmission module 3 serves as an important hub for changing the speed ratio, while the planetary locking wheel set is used to achieve the integrated operation of clamping and unscrewing the valve only through the transmission of the motor 2;

[0032] That is, by rotating the first planet carrier 34, the locking sun gear 81 drives the locking planet gear 82 to rotate, and then the locking planet gear 82 engages the inner ring gear 71, the synchronous drive ring 7 rotates, the gear head 561 is synchronously driven, and all the screws 56 rotate synchronously, thereby achieving equidistant extension and retraction of multiple drive arms 55 and avoiding single-point stress concentration; at the same time, the connection relationship between the gear head 561 and the screw 56 can adopt any existing structure, that is, the rotation of the gear head 561 can drive the screw 56 to rotate. It is worth mentioning that the height of the locking planet gear 82 here exceeds the locking sun gear 81 and the outer ring gear, and the exceeding portion is used to engage with the inner ring gear 71 of the synchronous drive ring 7;

[0033] The driving arm 55 is provided with an upper accommodating chamber 551 and a lower accommodating chamber 552. The upper accommodating chamber 551 and the lower accommodating chamber 552 are rotatably connected to the internal parts of the clamping claw 58, and a return spring 59 is provided between the clamping claw 58 and the inner wall of the driving arm 55. When work is required, the adjustable base 21 is placed under the valve and the height of the adjustable base 21 is adjusted. The valve handwheel squeezes the clamping claw 58 so that the clamping claw 58 retracts to the upper accommodating chamber 551 or the lower accommodating chamber 552. Then, when the valve handwheel is located between the upper accommodating chamber 551 and the lower accommodating chamber 552, that is, between the two clamping claws 58, the motor 2 is started, as shown in FIG. Figure 6 As shown, the clamping claw 58 of the upper accommodating chamber 551 can only be flipped downward, while the clamping claw 58 of the lower accommodating chamber 551 can only be flipped upward, thereby avoiding the problem of the valve handwheel falling out. At the same time, the clamping claw 58 of the lower accommodating chamber 551 is located on the spoke line of the valve handwheel, and a circumferential rotational force is applied to the spoke line of the valve handwheel by rotation, thereby opening the valve.

[0034] The adjustable base 21 includes a ball joint base 211, and the motor 2 is installed flat on the top of the ball joint base 211. A hemispherical hinge groove is provided at the bottom of the ball joint base 211. A damping rubber pad is glued and fixed to the inner wall of the hemispherical hinge groove, and the ball head of the universal joint is accommodated inside the hemispherical hinge groove. The universal joint is connected to a support screw 212, and the external thread of the support screw 212 is sleeved with a support leg 213. A self-balancing foot pad 218 is provided at the bottom of the support leg 213; the height is adjusted by rotating the support leg 213, and then the ball joint base 211 adapts to the tilt angle through the universal joint, and the damping rubber pad absorbs the vibration of the equipment; when installed on a slope, the main shaft of the motor 2 is always kept vertical by independent adjustment of the three legs to ensure the torque transmission efficiency.

[0035] In the manual valve electric operating device of the embodiment of claim 7, the self-balancing pad 218 is divided into a surface layer, a middle layer, and a bottom layer from top to bottom. The surface layer is a rubber gripping surface with barbs. The middle layer of the self-balancing pad 218 defines a hydraulic balancing chamber filled with a non-Newtonian fluid. The inner layer of the self-balancing pad 218 is provided with a titanium alloy support plate with a plurality of drainage holes. The surface barbs penetrate soft soil to provide initial grip. The non-Newtonian fluid hardens instantly under vibration and forms a rigid support. The drainage holes in the titanium alloy plate drain accumulated water to prevent slipping.
