Description
Technical Field
[0001] The utility model relates to a valve opening and closing device, in particular to an underground valve auxiliary opening and closing device. Background Art
[0002] Compared with traditional open channel water supply, pipeline water supply has significant advantages such as high efficiency and water saving, stable and controllable, safe and reliable. It has been widely promoted and applied in agriculture, industry and urban water supply and drainage. Valves, as important control components of water supply and distribution networks, are mainly installed on pipelines at all levels. They have functions such as cutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief to ensure that the water supply and distribution system operates stably at the set pressure and flow. In the water supply and distribution system, the sizes and styles of valves used in pipelines at all levels are different, but the commonly used valve adjustment devices are mainly handle type and handwheel type.
[0003] At present, pipelines at all levels of the water distribution network are generally buried below the surface. On the one hand, it reduces the floor space, and on the other hand, it can prevent aging or human damage and extend the service life of the pipeline. Valve wells are set at the valves installed on the pipelines at all levels. When the system needs to be repaired or there is a need for drainage in winter, the valves are opened and closed through the valve wells for maintenance or winter drainage. At present, the commonly used valve opening and closing method is still mainly for operators to enter the valve well for opening and closing. Due to the small space of the valve well, the operation is inconvenient, especially for narrow and deep valve wells or when the valve well is backflowing due to system leakage, it is not easy for operators to enter the valve well, which seriously affects the convenience of valve opening and closing.
[0004] In order to solve the problem of inconvenient opening and closing of underground valves, patent number ZL201821714050.6 discloses a valve opening / closing tool suitable for underground gate valves. However, the device has the following problems: (1) The distance between the two locking fingers is fixed and cannot be adjusted. When in use, it cannot adapt to valve handwheels (handles) of different sizes, which has certain limitations; (2) When performing maintenance at night, it is dark in the valve well and it is not easy for the staff to find the valve handwheel (handle) smoothly. Although they can carry a flashlight to assist in illumination, holding the flashlight in one hand is likely to affect the staff's operation. Utility Model Content

[0022] The utility model will be further described below in conjunction with the accompanying drawings.
[0023] See also Figure 1 and Figure 2The utility model of the downhole valve auxiliary opening and closing device comprises an adjusting connecting rod 1, a gripper 2, a gripper connecting bracket 3, a crank 4, a casing tube 5 and a handle 6. The gripper 2 is set to four, and each gripper comprises an adjusting plate 2-1, a connecting plate 2-2 and a valve adjusting plate 2-3 connected in sequence from top to bottom, wherein the adjusting plate and the connecting plate are movably connected by pins, and the valve adjusting plate 2-3 is fixedly connected to the connecting plate. The tops of the four adjusting plates 2-1 are all movably connected with U-shaped connecting rings 2-4, and four first pull rings 7 are fixed at the bottom of the U-shaped adjusting groove 8, and the U-shaped connecting ring 2-4 is connected to the first pull ring 7, and the top of the U-shaped adjusting groove 8 is connected to the connecting ring at the lower end of the adjusting connecting rod 1 through a second pull ring 9. The gripper connecting bracket 3 comprises two long right-angle steels and two short right-angle steels, and the four right-angle steels are sequentially butt-jointed along the circumferential direction, wherein the two long right-angle steels are diagonally arranged, and the two short right-angle steels are diagonally arranged. , forming a slide, the size of the slide matches the size of the U-shaped adjustment groove 8, the U-shaped adjustment groove 8 is located in the slide, moves up and down along the slide, a gap is provided at the joint of two adjacent right-angle steels, the width of the gap matches the thickness of the adjustment plate, the bottom ends of the four adjustment plates 2-1 respectively pass through the gap between the two adjacent right-angle steels, and can move up and down along the gap, the adjustment plate 2-1 and the connecting plate 2-2 are movably connected by pins, the outer walls of the lower ends and the upper ends of every two adjacent right-angle steels are fixedly connected by metal plates 13, and two brackets 14 are fixed at intervals on each metal plate 13 at the lower end, the connecting plate 2-2 is arranged in the gap between the brackets 14, and is movably connected to the brackets 14 by pins, the connection position of the connecting plate 2-2 can be set according to actual needs to ensure that the gripper can only adjust the opening in the set direction, and at the same time, it is convenient to fix the valve when opening (closing) the valve. A U-shaped connecting plate 10 is fixed at the top of the two long right-angle steels. The bottom end of the sheath tube 5 is fixed to the U-shaped connecting plate 10 through a semicircular clamp. The sheath tube 5 is sleeved outside the adjusting connecting rod 1. The adjusting connecting rod 1 moves up and down along the sheath tube 5. The handle 6 is fixed to the top of the sheath tube 5.
