[0030] Embodiment:

[0031] As shown in Figure 1 to Figure 8 the attached

[0032] The present utility model provides a water conservancy grille, which includes a grille frame 1 and a number of metal bars 2. On both sides of the top of the grille frame 1, a pair of first sliding grooves 3 are symmetrically provided. A sliding rod 4 is slidably installed in each of the pair of first sliding grooves 3. The top ends of the pair of sliding rods 4 are installed with an upper mounting frame 5. A number of upper L-shaped grooves 6 are equidistantly provided on one side of the upper mounting frame 5. Threaded holes 7 are provided at positions close to each upper L-shaped groove 6 at the top end of the upper mounting frame 5. A locking component is installed inside the sliding rod 4. A number of pairs of spherical positioning grooves 8 are equidistantly provided from top to bottom on both sides of the first sliding groove 3. At positions parallel to each upper L-shaped groove 6 at the bottom end inside the grille frame 1, lower L-shaped grooves 9 are provided. A lower slider 10 is installed at the bottom end of the metal bar 2. A second sliding groove 11 is provided at the top end of the metal bar 2. An extension plate 12 is slidably installed in the second sliding groove 11. An upper slider 13 is installed at the top end of the extension plate 12. A limiting plate 14 is installed at the top end of the upper slider 13. A bolt 15 is installed on one side of the top end of the limiting plate 14.

[0033] Among them, the size of the lower L-shaped groove 9 matches the size of the upper L-shaped groove 6.

[0034] Among them, the upper slider 13 and the lower slider 10 have the same size.

[0035] Among them, the size of the upper slider 13 matches the size of the upper L-shaped groove 6, so that the lower slider 10 can slide in the lower L-shaped groove 9 and the upper slider 13 can slide in the upper L-shaped groove 6. When the staff needs to remove the corroded and damaged metal bar 2, the bolt 15 above the metal bar 2 can be removed first, and then the metal bar 2 can be pulled along the lower L-shaped groove 9 and the upper L-shaped groove 6 to remove the metal bar 2.

[0036] Among them, the position and size of the bolt 15 respectively match the position and size of the threaded hole 7, which is convenient to fix the metal bar 2 through the bolt 15.

[0037] Among them, the locking component includes a third sliding groove 16 and several pairs of spherical mounting grooves 17. The third sliding groove 16 is opened at the top end of the sliding rod 4. The top end of the third sliding groove 16 is threadedly connected with a threaded block 18. The bottom end of the threaded block 18 is provided with a cylinder 19. Several trapezoidal blocks 20 are equidistantly installed on the circumferential side of the cylinder 19. Several pairs of spherical mounting grooves 17 are equidistantly opened on both sides of the sliding rod 4 from top to bottom, and the spherical mounting grooves 17 communicate with the third sliding groove 16. A ball 21 is movably installed in the spherical mounting groove 17. When it is necessary to adjust the length of the water conservancy grille, the staff can first rotate the knob 23, so that the knob 23 drives the threaded block 18, the cylinder 19 and the trapezoidal block 20 to move upward. Then the inclined surface at the bottom end of the trapezoidal block 20 moves to a position parallel to the ball 21. At this time, the ball 21 is no longer limited by the trapezoidal block 20 and can rotate and move in the spherical mounting groove 17, enabling the staff to directly pull the upper mounting frame 5 to realize the adjustment of the height of the extension plate 12. After the staff adjusts the extension plate 12 to a suitable position, the knob 23 can be rotated in the reverse direction, so that the trapezoidal block 20 moves downward. Then the side of the trapezoidal block 20 is closely attached to one side of the ball 21, squeezing and fixing the ball 21 in the spherical mounting groove 17. At this time, the other side of the ball 21 extends out from one side of the spherical mounting groove 17 and enters the spherical positioning groove 8 to realize the fixation of the sliding rod 4. In addition, the staff can add auxiliary lines at the position of each ball 21 to facilitate observing the position of the ball 21.

[0038] Among them, the upper mounting frame 5 is provided with a through groove 22 at a position directly above the third sliding groove 16, and the size of the through groove 22 matches the size of the third sliding groove 16.

[0039] Among them, the top end of the threaded block 18 is installed with a knob 23 through a connecting rod, and the knob 23 is located above the upper mounting frame 5, facilitating driving the threaded block 18 to rotate and move by rotating the knob 23.

[0040] Working principle of this embodiment: When using this water conservancy grille, the staff can install the water conservancy grille at a designated position through the grille frame 1, and then rotate the knob 23 according to the water level height, so that the knob 23 drives the threaded block 18, the column body 19 and the trapezoidal block 20 to move upward. Furthermore, the inclined surface at the bottom end of the trapezoidal block 20 moves to a position parallel to the ball 21. At this time, the ball 21 is no longer limited by the trapezoidal block 20 and can rotate and move in the spherical mounting groove 17, enabling the staff to directly pull the upper mounting frame 5 to adjust the height of the extension plate 12. After the staff adjusts the extension plate 12 to a suitable position, the knob 23 can be rotated in the reverse direction to make the trapezoidal block 20 move downward. Furthermore, the side of the trapezoidal block 20 is closely attached to one side of the ball 21, squeezing and fixing the ball 21 in the spherical mounting groove 17. At this time, the other side of the ball 21 extends out from one side of the spherical mounting groove 17 and enters the spherical positioning groove 8 to fix the slide bar 4. After this water conservancy grille has been used for a long time and some metal bars 2 are damaged, the staff can first remove the bolt 15 above the damaged metal bar 2, and then pull the metal bar 2 to slide along the lower L-shaped groove 9 and the upper L-shaped groove 6 to remove the metal bar 2.
