[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: an adjustable diversion channel device for water conservancy and hydropower projects, including a base 1, a first diversion cylinder 2, a second diversion cylinder 3 and an adjustment mechanism 6 on the base 1, a diversion cylinder 21 in the first diversion cylinder 2, a drainage cavity in the diversion cylinder 21, and a guide ring cavity 4 in the first diversion cylinder 2 and the second diversion cylinder 3, the adjustment mechanism 6 including an adjustment cylinder 61 and a sealing guide ring 62, the sealing guide ring 62 being integrally disposed around the adjustment cylinder 61, and the sealing guide ring 62 being embedded in the guide ring cavity 4 in the first diversion cylinder 2 and the second diversion cylinder 3, the adjustment cylinder 61 having a diversion cavity 611, the size of the diversion cavity 611 being adapted to the drainage cavity, and the diversion cavity 611 being connected to several sets of diversion pipes 63 respectively.

[0026] The regulating cylinder 61 of the regulating mechanism 6 is integrated with the sealing guide ring 62, and the sealing guide ring 62 is embedded in the guide ring cavity 4 of the first guide cylinder 2 and the second guide cylinder 3, so that the regulating cylinder 61 can rotate. By rotating the regulating cylinder 61, the guide cavity 611 can cooperate with the drainage cavity of the diversion cylinder 21. Combined with the use of multiple sets of guide pipes 63, the water flow path can be flexibly switched to achieve multi-directional diversion without the need to replace the entire device, which improves the flexibility to deal with different engineering scenarios and saves replacement costs and time.

[0027] Please see Figure 1-2 It is understood that a fixed retaining ring 11 is provided on the base 1, and positioning plates 5 are welded to the side walls of the first guide tube 2 and the second guide tube 3. The fixed retaining ring 11 and the positioning plate 5 have matching positioning holes.

[0028] The positioning plate 5, which is welded to the side wall of the first guide tube 2 and the second guide tube 3 by fixing the retaining ring 11, and the two are reserved with matching positioning holes, can be firmly fixed to the base 1 by bolts during actual installation. This improves the stability and firmness of the connection between the first guide tube 2, the second guide tube 3 and the base 1, and effectively avoids displacement and shaking of the first guide tube 2 and the second guide tube 3 during water flow impact or device operation.

[0029] Please see Figure 3-4 Understandably, the sealing guide ring 62 has a protruding positioning block 621, and the positioning block 621 is equipped with a pin 622. The fixed retaining ring 11 has multiple sets of through holes 111. The size of the pin 622 matches the through holes 111, and the pin 622 can be inserted into the through holes 111 accordingly.

[0030] When the regulating cylinder 61 rotates, the orifice diameters of the diverter cylinder 21 and the regulating cylinder 61 will change accordingly. Once the orifice diameter is adjusted to a suitable size for drainage, the pin 622 is inserted into the corresponding through hole 111, which can effectively fix the position of the regulating cylinder 61, prevent it from rotating unexpectedly under the impact of water flow, and ensure the stability and accuracy of the flow direction and flow distribution.

[0031] Please see Figure 4 It is understood that each flow guide cavity 611 is provided with an inner diameter thread, and each set of flow guide tubes 63 is spirally connected to the corresponding flow guide cavity 611.

[0032] Please see Figure 3-4 Understandably, the other end of the two sets of guide tubes 63 is connected to the expansion tube 64, and the other end of the two sets of guide tubes 63 is provided with a screw cavity 631. One end of the expansion tube 64 is provided with a stud 641, and the expansion tube 64 is spirally connected to the guide tube 63.

[0033] By setting the expansion pipe 64, the diameter of the diversion outlet can be changed according to the actual water supply needs, so that the device can be matched with subsequent water supply pipes or equipment of different specifications. At the same time, the spiral connection of the expansion pipe 64 can ensure that the diversion pipe 63 and the expansion pipe 64 are tightly connected, reducing the risk of loosening or leakage under the impact of water flow and ensuring the smoothness of water supply.

[0034] Please see Figure 1-3 It is understood that the second guide tube 3 is also provided with a support tray 31, and several sets of guide tubes 63 are set through the support tray 31. When the several sets of guide tubes 63 rotate with the adjustment mechanism 6, the support tray 31 can continuously support the guide tubes 63, effectively preventing the end of the guide tubes 63 away from the adjustment tube 61 from falling due to gravity or centrifugal force of rotation.

[0035] When using:

[0036] The first guide tube 2 and the second guide tube 3 are fixed by the positioning plate 5 and the fixing baffle ring 11 to form the main guide frame, and the water flow is introduced through the drainage cavity of the diversion tube 21;

[0037] When adjustment is required, rotate the regulating cylinder 61, and the sealing guide ring 62 on its periphery rotates synchronously in the guide ring cavity 4. The flow guiding cavity 611 rotates with the regulating cylinder 61 and forms different degrees of overlap with the drainage cavity of the diversion cylinder 21, changing the flow orifice to adjust the flow rate. At the same time, the multiple sets of flow guiding pipes 63 connected to the flow guiding cavity 611 switch the corresponding drainage direction to realize multi-path diversion.

[0038] Then, the pin 622 on the positioning block 621 is inserted into the through hole 111 of the fixing ring 11 to lock the position of the adjusting cylinder 61. Since the guide pipe 63 is spirally connected to the guide cavity 611, the expansion pipe 64 can be flexibly assembled to change the outlet specifications and adapt to different water supply needs. The support tray 31 in the second guide cylinder 3 supports the guide pipe 63 to prevent it from falling when rotating and to ensure smooth water flow.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
