[0002] Hydropower generation is the science and technology that studies the technical and economic issues of engineering construction and production operation that convert water energy into electrical energy. The water energy used in hydropower generation is mainly the potential energy contained in the water body. In order to realize the conversion of water energy into electrical energy, different types of hydropower stations need to be built.

The utility model achieves the advantage of good shock absorption effect by providing a base, a buffer mechanism, a support plate, a vortex-type water conservancy generator body, a shell, a rubber spring, a slide plate, a slide rod, a side plate and a second spring, and solves the problem of poor shock absorption effect of the existing vortex-type water conservancy generator. When people use the vortex-type water conservancy generator, there will be no strong vibration, and its internal components will not become loose, which will not affect its performance and is convenient for people to use.

[0004] When most of the load detection mechanisms of hydroelectric generators are being tested, strong vibrations will occur during the use of the hydroelectric generators. This will result in the ordinary detection mechanisms being unable to detect the electronic components of the working hydroelectric generators. In view of this, we propose a load detection mechanism for hydroelectric generators. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figures 1-4The utility model provides a load detection mechanism for a hydroelectric generator, including a hydroelectric generator body 1, a buffer platform 2 fixedly connected to the lower surface of the hydroelectric generator body 1, and a load detection mechanism 3 provided on the front surface of the buffer platform 2; the load detection mechanism 3 includes a detection machine body 31, and a display screen, control keys and emergency stop buttons are provided on the rear surface of the detection machine body 31. Through this arrangement, it is convenient for workers to install the module of the load detection mechanism in the detection machine body 31, thereby improving the installation effect of workers. The front surface of the detection machine body 31 is fixedly connected to a frame body 32, and a circular hole 33 is opened on the right surface of the frame body 32. An L-shaped sleeve rod 34 is slidably connected to the inner surface of the circular hole 33. The L-shaped sleeve rod 34 can be limited by the circular hole 33 so that the L-shaped sleeve rod 34 can only move in the circular hole 33, making the L-shaped sleeve rod 34 more stable. The front surface of the L-shaped sleeve rod 34 is fixedly connected to a gasket 35, and the gasket 35 is used to The L-shaped sleeve rod 34 is fixedly connected to one end of the elastic slide bar 36, and the other group of L-shaped sleeve rods 34 passes through the other end of the elastic slide bar 36 and is slidably connected to the elastic slide bar 36. The elastic slide bar 36 is composed of a spring and a slide bar. Through the setting of the elastic slide bar 36, it can be effectively ensured that the L-shaped sleeve rod 34 can contact the gasket 35 with the hydro-generator body 1 through the elastic force of the spring. The outer arc surface of the L-shaped sleeve rod 34 is fixedly connected to the positioning plate 4. The positioning plate 4 can limit the movement of the L-shaped sleeve rod 34 so that the L-shaped sleeve rod 34 will not fall out of the circular hole 33. The inner surface of the L-shaped sleeve rod 34 is fixedly connected to the wiring harness fixing shell 5. The frame 32, the L-shaped sleeve rod 34 and the gasket 35 are provided in two groups and are symmetrically arranged with the center line of the detection machine body 31 as the symmetry axis.

[0026] In this embodiment, through the arrangement of the detection machine body 31, the L-shaped sleeve rod 34 and the elastic slide rod 36, the elastic slide rod 36 uses a spring to enable the L-shaped sleeve rod 34 to drive the gasket to fit tightly against the electronic component, thereby facilitating the detection of the electronic component. At the same time, through the arrangement of the positioning plate 4 and the wiring harness fixing shell 5, the friction between the detection circuit and other objects is reduced, thereby improving the service life of the circuit.

[0027] Example 2

[0028] See also Figures 1-4On the basis of embodiment 1, the present invention provides a technical solution: preferably, a limiting mechanism 6 is provided on the upper surface of the frame 32, and the limiting mechanism 6 includes a sleeve plate 61, the lower surface of the sleeve plate 61 is fixedly connected to the upper surface of the frame 32, and the inner surface of the sleeve plate 61 is slidably connected with a slide plate 62, and the rear surface of the slide plate 62 is penetrated by an elastic conical rod 63, and the elastic conical rod 63 is composed of a spring and the conical rod. Through the setting of the conical rod, after the inclined surface of the conical rod is squeezed, the conical rod will shrink into the slide plate 62, and at the same time, the spring will be stretched. After being parallel to the card hole 8, the conical rod will be bounced into the card hole 8 through the elasticity of the spring, and the rear surface of the elastic conical rod 63 is fixedly connected to the limiting disk 64. The outer arc surface of the limiting disk 64 A rectangular groove 65 is provided on the surface, the slide plate 62 is hinged to one end of the bracket 7, and the L-shaped sleeve rod 34 is hinged to the other end of the bracket 7. The front surface of the sleeve plate 61 is provided with a card hole 8 in a circumferential array, and the rear surface of the frame 32 is provided with a slide groove 9. The rear surface of the slide plate 62 is fixedly connected to the connecting plate 10. The upper surface of the connecting plate 10 is penetrated by an elastic limiting plate 11. The elastic limiting plate 11 is composed of a spring and a limiting plate. The elasticity of the spring clamps the limiting plate in the rectangular groove 65, thereby limiting the elastic conical rod 63. After the gasket 35 contacts the electronic component, the elastic conical rod 63 is limited by the limiting plate, making the entire device more stable. The elastic limiting plate 11 is slidably connected to the rectangular groove 65.

[0029] In this embodiment, by setting the elastic conical rod 63, the slide 62, the sleeve plate 61 and the bracket 7, by sliding the slide 62 up and down, the L-shaped sleeve rod 34 can be controlled to extend and retract, ensuring that the L-shaped sleeve rod 34 can drive the gasket 35 to completely fit tightly with the electronic component, thereby improving the seismic resistance of the negative detection mechanism 3.

[0030] Working principle: when it is necessary to use the detection machine body 31 to detect the load of the hydro-generator body 1, the elastic limit plate 11 is pulled out of the rectangular groove 65, and the slide plate 62 is moved up and down. During the up and down movement of the slide plate 62, the inclined surface of the elastic conical rod 63 is squeezed by the sleeve plate 61 and will shrink into the slide plate 62. After being parallel to the card hole 8, the elastic conical rod 63 is bounced into the card hole 8 through the spring. When the slide plate 62 moves up and down, the bracket 7 will drive the L-shaped sleeve rod 34 to shrink in the circular hole 33, so that the distance between the two groups of L-shaped sleeve rods 34 becomes smaller, and at the same time the spring of the elastic slide rod 36 will be compressed. When the gasket 35 contacts the electronic component, the elastic limit plate 11 is re-inserted into the rectangular groove 65.
