[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment proposes a water-saving device for water conservancy construction, including a pipe body 1. A spigot 2 is provided on the pipe body 1, and an installation block 3 is fitted inside the spigot 2. A throttling plate 4 is fixedly connected to the inner wall of the installation block 3. A filter frame 5 is detachably connected to the throttling plate 4 via hexagonal bolts. An activated carbon filter screen 6 is fixedly connected inside the filter frame 5. A sealing gasket 7 is fixedly connected to the upper surface of the installation block 3, and an arc-shaped plate 8 is fixedly connected to the upper surface of the sealing gasket 7. A locking structure 9 for locking the arc-shaped plate 8 is provided on the pipe body 1. A handle 10 is fixedly connected to the upper surface of the arc-shaped plate 8. A sealing structure 11 is provided inside the pipe body 1. The throttling plate 4 plays a major role in water saving, the activated carbon filter screen 6 effectively filters impurities in the water flow to ensure water cleanliness, the sealing gasket 7 improves sealing performance, and the arc-shaped plate 8 facilitates assembly with the pipe body 1.

[0032] like Figure 1 , Figure 4 and Figure 5As shown, in a preferred embodiment, based on the above method, the locking structure 9 further includes two sets of fixing blocks 901 symmetrically fixed to the tube body 1. One set of fixing blocks 901 is rotatably connected to a bidirectional screw 902, and two displacement blocks 903 are symmetrically and threadedly connected to the bidirectional screw 902. The other set of fixing blocks 901 is fixedly connected to a guide rod 904, and two sliders 905 are symmetrically and slidably connected to the guide rod 904. A limiting ring 906 is fixedly connected between adjacent displacement blocks 903 and sliders 905, and the limiting ring 906 is slidably connected to the tube body 1. One end of the bidirectional screw 902 is fixedly connected to a first worm gear 908 via a connecting shaft 907, near... A bracket 909 is fixedly connected to the fixing block 901 of the first worm gear 908. A first worm 9010, which meshes with the first worm gear 908, is rotatably connected inside the bracket 909. A knob 9011 is fixedly connected to the top of the first worm 9010. The knob 9011 drives the first worm 9010 to rotate, which in turn drives the first worm gear 908, which meshes with the first worm 9010, to rotate. This causes the bidirectional screw 902 to rotate. The rotation of the bidirectional screw 902 causes the two shifting blocks 903 and the limiting ring 906 to move inward or outward at the same time. This facilitates locking and unlocking the arc plate 8, and also facilitates disassembly of the activated carbon filter 6.

[0033] like Figure 1 , Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, the sealing structure 11 further includes a rotating shaft 1101 rotatably mounted on the pipe body 1, a blocking plate 1102 fixedly connected to the rotating shaft 1101, a sealing ring 1103 fixedly connected to the outer peripheral sidewall of the blocking plate 1102, a second worm gear 1104 fixedly connected to the top end of the rotating shaft 1101, a second worm 1105 meshing with one side of the second worm gear 1104, and both ends of the second worm 1105 rotatably connected to... The connecting piece 1106 is fixedly connected to the bottom end of the pipe body 1. A handwheel 1107 is fixedly connected to one end of the second worm gear 1105. By rotating the handwheel 1107, the second worm gear 1105 is rotated, which in turn drives the second worm wheel 1104 meshing with the second worm gear 1105 to rotate, ultimately causing the blocking plate 1102 to rotate around the rotating shaft 1101, thus blocking the water flow in the pipe body 1. The design of the sealing ring 1103 ensures the sealing between the blocking plate 1102 and the pipe body 1.

[0034] like Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, a limiting block 1108 is further provided on one side of the blocking plate 1102, and the limiting block 1108 is fixedly connected to the inner wall of the pipe body 1; it plays a limiting role for the blocking plate 1102, ensuring that the blocking plate 1102 rotates into place when sealing.

[0035] like Figure 1 As shown, in a preferred embodiment, based on the above method, two pressure measuring tubes 12 are symmetrically and fixedly connected to the tube body 1 and communicate with it. The top end of the pressure measuring tube 12 is provided with a sealing plug 13; to facilitate the measurement of water pressure.

[0036] like Figure 3 As shown, in a preferred embodiment, based on the above method, a throttling hole 14 is further provided at the center of the throttling plate 4. The throttling hole 14 is circular in shape and can adjust the flow rate of the water.

[0037] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a rubber sleeve is further provided on the handle 10, and the outer surface of the rubber sleeve is provided with anti-slip grooves; this improves the comfort of operation and prevents accidental operation due to hand slippage.

[0038] Specifically, when using this water conservancy construction flow-saving device: when the filter screen needs to be cleaned, the handwheel 1107 is turned to drive the second worm 1105 to rotate, which in turn drives the second worm wheel 1104 meshing with the second worm 1105 to rotate, ultimately causing the blocking plate 1102 to rotate around the rotating shaft 1101, so that the blocking plate 1102 is released from the limiting block 1108, blocking the water flow in the pipe body 1. Then, the knob 9011 is turned to drive the first worm 9010 to rotate, which in turn drives the first worm wheel 908 meshing with the first worm 9010 to rotate, thereby causing the bidirectional screw 902 to rotate. The rotation of the bidirectional screw 902 causes the two displacement blocks 903 and the limiting ring 906 to move outward simultaneously. Then, the activated carbon filter screen 6 is pulled out of the pipe body 1 by holding the handle 10 for cleaning, which significantly reduces the difficulty of disassembly and assembly.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
