During this process, the trigger component 103 will collide with the oil pressure pipe outlet of the hydroelectric unit. At this time, the trigger component 103 will slide upward and transmit the parallel force to the conversion component 201. The conversion component 201 will convert the translational force into a rotational force and drive the output component 202 to rotate around the center of the circle. During the rotation of the output component 202, the sealing component 203 will also be driven to move in the functional component 102. At the same time, the sealing component 203 will also preliminarily fix the outer wall of the oil pressure pipe outlet of the hydroelectric unit.

The mounting tube 101b is located at the arc groove 101c. An output slot 102a is provided on the inner wall, a connecting conversion slot 102b is provided on the side of the output slot 102a of the mounting tube 101b, a limiting slot 102c is provided above the conversion slot 102b of the mounting tube 101b, an unlocking slot 102d is provided on the outer side of the mounting tube 101b, and the oil pressure of the hydropower unit is monitored through the pressure transmitter body 101a. Compared with the past, the traditional low oil pressure measuring device of the hydropower unit only uses a single pressure switch, which can also prevent accidental touching. The trigger component 103 is placed in the arc groove 101c, and the trigger component 103 can also be guided. The conversion component 201 is placed in the conversion slot 102b, and the conversion slot 102b is also connected to the output slot 102a, so that the conversion component 201 can be toggled during the movement of the trigger component 103.

[0037] Furthermore, the trigger assembly 103 includes a convex plate 103a arranged in the arc groove 101c, a limiting rod 103b arranged at the end of the convex plate 103a, and an L-shaped movable rod 103c arranged in the output groove 102a.

[0038] Furthermore, the conversion assembly 201 includes a conversion rod 201a arranged in the conversion groove 102b, a spiral groove 201b opened outside the conversion rod 201a, and a rotating rod 201c arranged at the end of the conversion rod 201a.

The L-shaped moving rod 103c is movably connected in the spiral groove 201b, and the end of the conversion rod 201a is fixedly connected to the rotating rod 201c. The rotating rod 201c penetrates the conversion groove 102b and extends into the limit groove 102c. The configuration of the conversion rod 201a is to convert the translational force into a rotational force and transmit it to the limit groove 102c through the rotating rod 201c when the L-shaped moving rod 103c moves.

[0039] Operation process: Align the bottom of the installation tube 101b with the installation position of the hydropower unit, and then press the pressure transmitter body 101a downward, so that the convex plates 103a on both sides collide with the oil pressure pipe of the hydropower unit, and then the convex plates 103a and the limit rod 103b move upward. The limit rod 103b will move to both sides along the arc while in the sliding groove B2, so that the limit rods 103b on both sides drive the convex plates 103a on both sides to move into the arc groove 101c. When moving to the moving height, the convex plate 103a 03a will conflict with the L-shaped conflicting rod, and the purpose of force transmission can be achieved. When the convex plate 103a rises to the top of the arc groove 101c, the convex plate 103a will be guided into the arc groove 101c by the limiting rod 103b. At this time, there will be no obstruction between the mounting pipe 101b and the oil pressure pipe of the hydropower unit. In addition, during the rising process of the L-shaped conflicting rod, the spiral groove 201b will be moved, so that the conversion rod 201a will rotate along the trajectory of the spiral groove 201b, thereby realizing the conversion and transmission of force.

[0040] Example 2

[0041] Reference Figures 1 to 7, which is the second embodiment of the utility model.

During the rotation of the toggle rod 202a, the contact plate 203a will move against the movable rod 202c. At this time, the movable rod 202c will follow the contact plate 203a to move in the limit groove 102c. During the movement, the arc baffle 203b and the sealing ring 203c will be driven to move toward the oil pressure pipe of the hydropower unit. When the convex plate 103a completely enters the arc groove 101c, the oil pressure pipe of the hydropower unit will conflict with the monitoring end of the pressure transmitter body 101a. At the same time, the arc baffle 203b and the sealing ring 203c will fit at the connection between the oil pressure pipe of the hydropower unit and the pressure transmitter body 101a, thereby increasing its sealing performance and completing the preliminary installation of the pressure transmitter body 101a.

Different from the previous embodiment, it also includes a locking component 300; it includes a plug-in component 301 arranged outside the output component 202, and a fixing component 302 arranged at the end of the plug-in component 301. During the movement of the above-mentioned output component 202, the plug-in component 301 will be driven to move toward the center of the unlocking groove 102d, and at the same time, the fixing component 302 is controlled to conflict with the plug-in component 301 to achieve locking.

[0047] Furthermore, the plug-in assembly 301 includes an L-shaped fixing rod 301a arranged at the end of the movable rod 202c, a T-shaped notch 301b opened outside the L-shaped fixing rod 301a, a plug-in rod 301c arranged at the end of the L-shaped fixing rod 301a, and a functional groove 301d opened outside the plug-in rod 301c, the fixing assembly 302 includes a support rod 302a arranged in the functional groove 301d, a rotating plate 302b arranged outside the support rod 302a, and an action spring 302c connected to the rotating plate 302b, the separated ends of the movable rods 202c on both sides pass through the mounting tube 101b and are fixedly connected with the L-shaped fixing rod 301a, the outer sides of the L-shaped fixing rods 301a on both sides are slidably connected in the locking groove, the end of the L-shaped fixing rod 301a on one side is opened with a T-shaped notch 301b, and the end of the L-shaped fixing rod 301a on the other side is fixedly connected There is a plug-in rod 301c, and a pair of functional grooves 301d are provided on the outer side of the plug-in rod 301c.
