Technical Field

[0001] The utility model relates to a portable pipeline gate opener, belonging to the technical field of water conservancy engineering and fluid control. Background Art

[0002] With the continuous development of global water resource management and water conservancy projects, pipeline gate openers have become an important component of water conservancy projects. They are mainly used to control the opening and closing of water flows and prevent risks caused by excessive water levels. In addition, in some narrow or complex environments, the design of pipeline gate openers takes into account the operator's convenience, enabling flexible operation of gate valves in confined spaces.

[0003] At present, facing the increasingly high-quality demands of modern water conservancy, traditional pipeline gate openers have also shown many problems. For example, patent application CN206458876U discloses a controllable electric valve opening device for a light-and-dark lever manual valve. This device is mainly designed for vertical gate valve operation and lacks adaptability to non-vertical valves. This single applicability limits its multi-angle operation under various complex water conservancy conditions. It also leads to the need to prepare multiple tools to deal with different situations, which makes the operation very cumbersome. In addition, when the water level is high or the water overflows the gate valve, the operator is often unable to effectively find the position of the gate valve, resulting in many difficulties, increased operational risks and delays, and may reduce the efficiency of water resource management.

[0004] Therefore, it is necessary to design a new type of portable pipeline gate opener that can be operated at multiple angles under different water conservancy conditions, is easy to operate and efficient, and can observe the status of the valve in an underwater environment to meet the needs of convenience, efficiency and safety in water conservancy pipeline projects.

[0023] The bottom of the connecting portion 25 is provided with L-shaped long arm mounting bases extending to the left and right in opposite directions. The long arms are provided with long arm through holes 21 corresponding to the fixing through holes 20 of the housing 18. Screws are passed through the long arm through holes 21 and the fixing through holes 20, respectively, to secure the connecting portion 25 to the housing 18. The middle portion of the connecting portion 25 is a hollow tube, which encloses the exposed portion of the first rotating shaft 16. The top of the connecting portion 25 is provided with an annular clamp 19, which includes an annular locking wall ring 194 and a locking bolt 193. The side wall of the annular locking wall ring 194 is provided with a threaded through hole 192, and the locking bolt 193 is screwed into the threaded through hole 192.

[0030] During use, with the worm gear box 24 facing the gate valve vertically, the extension rod 10 is connected to the operating rod 1, and the first interface 3 at the bottom of the operating rod 1 is connected to the operating interface 9 at the top of the worm gear box 24. Depending on different situations, the electric valve opener 12 or the spare manual operation key 11 is selected to connect to the operating rod 1 to provide rotational power to open and close the butterfly valve 26.

[0031] During use, when the worm gear box 24 facing the gate valve is not vertical, the extension rod 10 is connected to the operating rod 1, and the operating rod 1 is connected to the reversing interface 2. At this time, the tube wall of the operating rod 1 is inserted into the clamp 19, and the annular locking wall ring 194 of the clamp 19 is fixed to the outer wall of the operating rod 1 by screwing, and then the locking bolt 193 is rotated for secondary fixation; thereafter, the angle of the reversing interface 2 can be adjusted to connect with the operating connector 9 at the top of the worm gear box 24. According to different situations, an electric valve opener 12 or a spare manual operation key 11 is selected to connect with the operating rod 1 to provide rotational power. Through the bevel gear structure of the reversing interface, when the operating rod 1 rotates, the gear engagement drives the second rotating shaft 17 to rotate synchronously to complete the operation of opening and closing the butterfly valve 26.

[0032] By adopting the above technical solution, the portable pipeline gate opener of the present utility model is provided with a detachable reversing interface 2. When encountering a non-vertical gate valve, the operator can flexibly adjust the gate valve opening and closing operation by connecting the reversing interface 2, adapting to various pipeline conditions.
