Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] The present invention will be further described below with reference to the accompanying drawings:

[0035] Example 1

[0036] As attached Figure 1 To be continued Figure 4 As shown:

[0037] This embodiment provides a water intake construction device for the upstream face of an earth-rock dam under reservoir impoundment conditions. It includes a water intake device 1, with several sections of water conveyance pipe 2 connected to the device. Flanges 3 are installed at both ends of each section of the water conveyance pipe 2, and a traction device 4 is mounted on the outside of the pipes. Several supports 11 are installed inside the water intake device 1, and a plurality of slide rails 12 are installed on each support 11. A sliding platform 13 is installed between the slide rails 12, and a submersible pump 14 is fixed above the sliding platform 13. A carrier plate 131 is installed inside the sliding platform 13, and a plurality of sliders 132 are installed below the carrier plate 131. A traction bracket 133 is fixed between the rear surfaces of the sliders 132. Connecting blocks 1321 are installed on the surface of each slider 132. A rear support shovel block 1323 is fixed below the connecting block 1321, and a shovel plate 1322 is installed in front of the rear support shovel block 1323. A plurality of auxiliary pulleys 1324 are installed on the rear support shovel block 1323.

[0038] Furthermore, water supply pipe 2 can be made of PE pipe, steel pipe or other pipe materials, and its diameter is determined in combination with the water intake scale.

[0039] Furthermore, flange 3 can be made of stainless steel or plastic, and its specifications and dimensions need to be selected according to the diameter of the water supply pipe.

[0040] Furthermore, the support pier 11 can be a reinforced concrete support pier or a supporting structure such as a steel truss; it is fixed on the upstream slope of the earth-rock dam, and the size and spacing of the support pier need to be adjusted according to the project layout.

[0041] Furthermore, the slide rail 12 can be selected according to its specifications, the water intake scale, and the load of the upper slide platform 13 and the submersible pump 14. The dimensions of the slide rail 12 are manufactured and installed according to the dimensions of the upper submersible pump 14.

[0042] The specific working principle is as follows:

[0043] This invention involves installing the support piers 11 within the water intake device 1 onto the earth-rock dam, arranging them at the required spacing to the top of the dam, and fixing the traction device 4 at the top of the dam. Then, at least two slide rails 12 are installed on the support piers 11. After installation, a submersible pump 14 is fixed above the slide platform 13 and installed on the surface of the carrier plate 131. The slider 132 is installed in conjunction with the slide rails 12. The rear support shovel block 1323, fixed below the connecting block 1321, nests with the slide rail 12. The auxiliary pulley 1324 slides against the side wall of the slide rail 12, while the shovel plate 1322 adheres to the surface of the slide rail 12 to push away foreign objects and silt deposited on the slide rail 12. Finally, the submersible pump 14 is connected to the water supply pipe 2 via a flange 3. As the reservoir water level changes, the traction device 4 is released in length. The traction bracket 133 and the traction rope connected to the submersible pump 14 move towards the upstream face of the reservoir along with the slide platform 13, completing the water intake work on the upstream face of the earth-rock dam.

[0044] Example 2:

[0045] As attached Figure 5 To be continued Figure 6 As shown:

[0046] The submersible pump 14 includes a fixed base 141, a pump body 142 mounted on top of the fixed base 141, a conduit 143 mounted on the pump body 142, and a pump head 144 connected to the front of the pump body 142. The pump head 144 includes a pump head mesh ring 1441, which has multiple mesh-covered side water channels 1442. An inlet 1446 is located in the center of the pump head 144, and a rotating seat 1443 is fixed to the outer surface of the inlet 1446. A shaft bracket 1444 is erected on the rotating seat 1443, and multiple toothed plates 1445 are mounted on the shaft bracket 1444.

[0047] Furthermore, the submersible pump 14 must be a submersible pump with variable frequency regulation function and fixed on the slide rail 13. Its parameters and model must be determined in conjunction with the water intake scale and layout elevation of the project.

[0048] The specific working principle is as follows:

[0049] This invention fixes the pump body 142 to the fixed base 141, connects the conveying pipe 2 to the conduit 143, and fixes the pump head 144 to the pump head screen ring 1441, covering its inlet 1446. When the pump body 142 is turned on, the water in the reservoir enters through the pump head screen ring 1441 covered with a filter screen and the side inlet groove 1442. The inlet 1446 forms a water suction vortex, which drives the toothed plate 1445 on the rotating shaft frame 1444 on the rotating base 1443 to rotate at high speed, thereby cutting off some long strip-shaped foreign objects in the water that enter the pump head screen ring 1441, preventing long strip-shaped foreign objects from entering the pump body 142 and causing entanglement of the internal structure, which would lead to abnormal water intake of the conduit 143.

[0050] Example 3:

[0051] As attached Figure 7 To be continued Figure 8 As shown:

[0052] The traction device 4 includes a platform 41, on which a pipe rack 42 is fixed. A touch box 43 is located beside the pipe rack 42. A hinged swing cover 44 is installed on the outside of the touch box 43, and a rain cover 45 is installed inside the touch box 43. A cable reel 46 is located below the rain cover 45. The touch box 43 has an inner cavity 431, and a cover plate mounting groove 432 is opened on its outer wall. A drive shaft rotator 433 is installed in the inner cavity 431, and a drive motor 434 is installed on the side wall of the drive shaft rotator 433.

[0053] Furthermore, the pulling rope on the cable drum 46 can be made of steel wire rope, with one end connected to the submersible pump 14 and the traction bracket 133, and the other end connected to the cable drum 46 fixed on the top of the dam.

[0054] The specific working principle is as follows:

[0055] This invention fixes the platform 41 to the top of the dam and installs the water pipe 2 with the surface-fixed pipe frame 42. In use, the hinged swing cover 44 is lowered by the cover plate mounting groove 432 to expose its inner cavity 431. Then, the drive motor 434 is turned on, which drives the drive shaft rotator 433 to rotate the cable drum 46 under the rain cover 45, thereby realizing the winding and releasing of the traction rope. This changes the position of the slide platform connected to the traction rope and the submersible pump above it on the slide rail, adapting to the reservoir water level adjustment at different times.

[0056] It should be understood that the embodiments disclosed herein are not limited to the specific processing steps or materials disclosed herein, but should be extended to equivalent substitutions of such features as understood by those skilled in the art. It should also be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting.

Therefore, phrases or "embodiments" appearing in various places throughout the specification do not necessarily refer to the same embodiment.
