Specific embodiments

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment: Refer to Figures 1-4An intelligent acquisition device shown in the figure includes a water inlet pipe 1, on which a valve 17 is installed. One end of the water inlet pipe 1 is fixedly installed with an upper node cabin 2 that is connected and communicated. The bottom of the upper node cabin 2 is fixedly installed with a connecting pipe 3 that is connected and communicated. The bottom end of the connecting pipe 3 is fixedly installed with a lower node cabin 4 that is connected and communicated. The bottom end of the lower node cabin 4 is fixedly installed with a water outlet pipe 5 that is connected and communicated. A vertical sliding hole is opened on the inner wall of the top of the lower node cabin 4, and a vertical rod 7 is slidably installed in the vertical sliding hole. The bottom end of the vertical rod 7 extends into the lower node cabin 4 and is fixedly installed with a baffle 6. The top of the baffle 6 corresponds to the bottom end of the connecting pipe 3. The top end of the vertical rod 7 extends outside the vertical sliding hole and is fixedly installed with a cross plate 8. A sealing box 21 is fixedly installed on the side of the upper node cabin 2. The top of the cross plate 8 is fixedly connected to the bottom end of the sealing box 21 through an elastic device 20. A distance sensor 9 is fixedly installed on the side of the lower node cabin 4, and the distance sensor 9 corresponds to the position of the cross plate 8.

[0026] With the above structure: during use, the water inlet end is connected through the water inlet pipe 1, and the water inlet end of the water turbine generator is connected through the water outlet pipe 5. By opening the valve 17, water can pass through the water inlet pipe 1, the closing ring 15, the upper node cabin 2, the connecting pipe 3, the lower node cabin 4, and the water outlet pipe 5, and then enter the water turbine generator for power generation. When water enters the lower node cabin 4 through the connecting pipe 3, since the baffle 6 blocks the bottom end of the connecting pipe 3, due to the impact force of the water, the baffle 6 moves downward. The movement of the baffle 6 drives the vertical rod 7 to move downward, so that the cross plate 8 moves downward, and the elastic device 20 deforms. The distance sensor 9 is used to judge the moving distance of the cross plate 8, so as to judge the size of the water flow according to the amount of the distance, and thus collect the water flow information.

[0027] The elastic device 20 can adopt a metal spring or a gas spring. The magnitude of the elastic tension of the elastic device 20 can be selected according to actual needs.

[0028] According to the actual situation on site, the elastic device 20 can be installed at the bottom of the upper node cabin 2, or at the bottom of the sealing box 21. Of course, it can also be installed on another fixed bracket.

[0029] In this embodiment, a controller 10 is also fixedly installed on the lower node cabin 4. The controller 10 is electrically connected to the distance sensor 9, and the measurement signal of the distance sensor 9 is analyzed by the controller 10.

[0030] See Figure 3 , specifically, there are gaps between the four sides of the baffle 6 and the four inner walls of the lower node cabin 4, and the top area of the baffle 6 is larger than the area of the bottom end of the connecting pipe 3. The advantage of such a setting is that when the baffle 6 moves downward, water can enter the water outlet pipe 5 through the lower node cabin 4.

[0031] In this embodiment, a vertical sealing groove is formed on the inner wall of the vertical sliding hole. A vertical sealing gasket 11 is installed in the vertical sealing groove, and the vertical sealing gasket 11 contacts the side of the vertical rod 7. Through the arrangement of the vertical sealing gasket 11, sealing is facilitated.

[0032] A valve 17 is installed on the water inlet pipe 1 to control the opening and closing of the water flow of the entire device. The valve 17 can be a manual valve or an automatically controlled valve such as an electric or pneumatic valve.

[0033] Embodiment 2:

[0034] Referring to FIGS. 3 and 4, an automatic adjustment device for a water turbine generator set includes a closed ring 15 fixedly installed on the inner wall of the water inlet pipe 1. The valve 17 is located on the side of the closed ring 15 away from the sealing box 21. A tapered table 16 is provided in the water inlet pipe 1, and the tapered table 16 corresponds to the position of the closed ring 15. The tapered table 16 is located on the side of the closed ring 15 away from the upper node cabin 2. Two horizontal rods 13 are fixedly installed on the side of the tapered table 16. Two horizontal sliding holes are formed on the inner wall of the upper node cabin 2, and the two horizontal rods 13 are respectively slidably installed in the two horizontal sliding holes. A sealing box 21 is fixedly installed on the side of the upper node cabin 2 away from the water inlet pipe 1. One end of each of the two horizontal rods 13 away from the tapered table 16 extends into the sealing box 21. A gear mechanism is installed in the sealing box 21, and the gear mechanism is connected to the cross plate 8 and the two horizontal rods 13; the gear mechanism includes a rotating shaft rotatably installed on the inner walls of both sides of the sealing box 21. A gear 12 is fixedly sleeved on the rotating shaft. A rack 14 is fixedly installed at the bottom of each of the two horizontal rods 13, and the two racks 14 are both meshed with the gear 12. An activity hole is formed at the bottom of the sealing box 21, and an activity rod 18 is slidably installed in the activity hole. The bottom end of the activity rod 18 is fixedly connected to the top of the cross plate 8. A tooth groove is formed on the side of the activity rod 18, and the tooth groove is meshed with the gear 12.

[0035] Referring to Figure 4 , when the cross plate 8 moves, it drives the activity rod 18 to move. The activity rod 18 drives the gear 12 to rotate through the tooth groove. The rotation of the gear 12 drives the rack 14 to move. The movement of the rack 14 drives the horizontal rod 13 to move. The movement of the horizontal rod 13 drives the tapered table 16 to move. The tapered table 16 moves towards the closed ring 15. When the water flow rate at the connecting pipe 3 increases, the baffle 6 is far from the connecting pipe 3, and the tapered table 16 approaches the closed ring 15, thereby reducing the water flow volume between the closed ring 15 and the tapered table 16. When the water volume at the connecting pipe 3 decreases, the baffle 6 is close to the connecting pipe 3, and the tapered table 16 moves away from the closed ring 15, thereby increasing the water flow volume between the closed ring 15 and the tapered table 16, thus realizing automatic adjustment.

[0036] A horizontal sealing groove is formed on the inner wall of the horizontal sliding hole. A horizontal sealing gasket 19 is installed in the horizontal sealing groove. The inner wall of the horizontal sealing gasket 19 contacts the side of the horizontal rod 13. Through the arrangement of the horizontal sealing gasket 19, sealing is carried out.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
