[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0020] Embodiment 1, as Figure 1 As shown, a device for manually opening an electromagnetic quick isolation valve comprises a swing arm 3 with a weight 2 at the end thereof arranged on a valve body 1, a winch 4 installed with the help of the valve body 1, a valve plate of the isolation valve is connected to the swing arm 3, a pull rope 5 is arranged on the winch 4, a hanging ring 6 is arranged on the swing arm 3, one end of the pull rope 5 is connected to the hanging ring 6, the axes of the winch 4 and the swing arm 3 are arranged in sequence from high to low, the valve plate is closed when the swing arm 3 falls to the final position, the swing arm 3 is reset after rotating 90°, and the valve plate is fully opened.

[0021] In this embodiment, the pull rope 5 is connected to the hanging ring 6 by means of a hook. By rotating the winch 4, the pull rope 5 is contracted and tightened, and the weight 2 and the swing arm 3 are pulled up under the drag of the pull rope 5 until the swing arm 3 reaches the initial position and then the swing arm 3 is fixed. The winch 4 can be a manual winch or a mechanical winch. In this embodiment, a manual winch with a self-locking device is preferred. The device has a simple structure and is easy to maintain. There is no need to manually lift the weight 2 and the swing arm 3, which saves time and effort. It has higher safety during operation and prevents the weight 2 from falling off and injuring or squeezing the body of the staff.

[0022] The lower end of the swing arm 3 is provided with a horizontal plate 7 and a vertical plate 8 which are connected to each other. The swing arm 3 is connected with the horizontal plate 7 and the vertical plate 8 to form a triangular structure, which is firmly connected. The hanging ring 6 is arranged on the horizontal plate 7. When the pull rope 5 is tightened and dragged, the rotation process of the swing arm 3 is made smoother, which effectively prevents the swing arm 3 from vibrating and causing wear of parts.

[0023] The swing arm 3 rotates around an axis, and the axial direction of the hanging ring 6 is arranged parallel to the axis.

[0024] Embodiment 2, as Figure 2-4 As shown, this embodiment is basically the same as the embodiment 1, except that the pull rope 5 includes a first rope body 9 whose upper end is fixed to the winch 4, and a second rope body 10 whose lower end is fixed to the hanging ring 6, and the lower end of the first rope body 9 is connected to the upper end of the second rope body 10 by means of a quick-connect assembly. The use of a hook is omitted to prevent the hook from shaking and accidentally hooking other equipment or parts after being removed from the hanging ring 6, causing damage.

[0025] The quick-connect assembly includes a fixed plate 11 arranged at the lower end of the first rope body 9 and a quick connector 12 arranged at the upper end of the second rope body 10. The fixed plate 11 is provided with a T-slot 13. The quick connector 12 includes a transverse plate 14 and a longitudinal plate 15 perpendicular to the transverse plate 14. The transverse plate 14 is perpendicular to the first rope body 9 and the second rope body 10 in a taut state. The transverse plate 14 and the longitudinal plate 15 form a T-shaped structure and are matched with the T-slot 13. The end of the longitudinal plate 15 is connected to the upper end of the second rope body 10. When the swing arm 3 needs to be reset, the quick connector 12 of the T-shaped structure is placed in the T-slot 13 on the fixed plate 11, the winch 4 rotates, and the first rope body 9 tightens the second rope body 10 with the help of the contact and cooperation between the transverse plate 14 and the T-slot 13 in the quick connector 12, thereby realizing the rotation of the swing arm 3. The connection method between the quick connector 12 and the fixed plate 11 is convenient and easy to operate, with a simple structure. The quick connector 12 and the fixed plate 11 have no hook-type structure. The lower end of the quick connector 12 is connected to the upper end of the second rope body 10. The quick connector 12 and the fixed plate 11 are opened and fall under the action of gravity. There is no hook structure on the fixed plate 11, which effectively reduces the probability of hooking other equipment or parts.

[0026] The bottom surface of the transverse plate 14 is provided with an arc-shaped protrusion 16, and the T-slot 13 is provided with an arc-shaped groove matching the arc-shaped protrusion 16. A gap is provided between the upper surface of the T-slot 13 and the transverse plate 14. The setting of the gap facilitates the quick connector 12 to be placed in the T-slot 13 and to cooperate with the T-slot 13. The arc-shaped protrusion 16 cooperates with the arc-shaped groove in the T-slot 13, so that the installation of the quick connector 12 and the fixing plate 11 is more secure. When the pull rope 5 is tightened, the first pull rope 9 and the second pull rope 10 are both in a tightened state, and the arc-shaped protrusion 16 and the arc-shaped groove in the T-slot 13 are in a tightened state. The arc groove in the T-slot 13 is pressed tightly, and the quick connector 12 will not be separated from the T-slot 13 without being subjected to other forces, thereby preventing the quick connector 12 from slipping off the T-slot 13 during the tightening of the pull rope 5, and the safety performance of the pull rope 5 is improved; after the work is completed, the quick connector 12 is lifted along the axial direction of the T-slot 13, and the arc-shaped protrusion 16 is separated from the arc groove, and the quick connector 12 can be removed from the fixing plate 11. The structure is simple and the operation is convenient, and the quick connector 12 and the fixing plate 11 can be quickly installed, fixed and disassembled.

[0027] A magnet 17 is provided in the T-slot 13, and the transverse plate 14 or the longitudinal plate 15 is attracted to the magnet 17. In this embodiment, the transverse plate 14 and the longitudinal plate 15 are made of iron. When the quick connector 12 is placed in the T-slot, the magnet 17 has an attractive force on the quick connector 12, further preventing the quick connector 12 from falling off during operation.
