[0025] The following is combined with Figure 1-4 The utility model is described in further detail.

[0026] Embodiment 1, refer to Figure 1 In order to solve the problem that the gap of the fence is adjusted by replacing the fence in the present embodiment, which is not only troublesome but also labor-intensive, and the fish in the fishway need to be blocked during replacement, thus affecting the passage efficiency of the fish, the utility model discloses a fishway grille mechanism, including a fixing mechanism 2, the fixing mechanism 2 includes two groups of fixing frames 21, a support column 22 is rotatably connected between the two groups of fixing frames 21, an adjusting mechanism 3 is provided in front of the support column 22, a fence 1 is provided on the adjusting mechanism 3, and a rotating mechanism 4 is provided on the left side of the left fixing frame 21.

[0027] Based on the above features, the working principle of this embodiment is: the fence 1 is a plurality of groups of connecting rods arranged closely, and the plurality of groups of connecting rods are hinged. When in use, the fence 1 is fixed on the river channel by the fixing mechanism 2, the rotating mechanism 4 is started to drive the adjusting mechanism 3 to rotate, and the adjusting mechanism 3 drives the fence 1 to rotate so that the fence 1 contacts the bottom of the river channel to block the fish, and the adjusting mechanism 3 is pulled to control the gap of the fence 1.

[0028] Example 2, refer to Figure 2-4 In this embodiment, in order to solve the problem that the gap of the fence is adjusted by replacing the fence, which is not only troublesome but also labor-intensive, and the fish in the fishway need to be blocked during replacement, which affects the passage efficiency of the fish, based on the same concept as the above-mentioned embodiment 1, the fishway grille mechanism also includes two groups of fixed frames 21, the bottoms of which are fixedly connected to fixed bases 23, the adjustment mechanism 3 includes a slide groove 31, the slide groove 31 is opened in front of the support column 22, the front left side of the support column 22 is fixedly connected to the fixed column 32, and two groups of slide rods 34 are arranged in the slide groove 31. A sliding member 35 is sleeved on the outer side, and the sliding member 35 is slidably connected to the two sets of sliding rods 34. An adjusting column 33 is fixedly connected to the front of the sliding member 35. The fence 1 is arranged between the adjusting column 33 and the fixed column 32. The sliding member 35 is a locking slider. An operating rod 351 is arranged on the right side of the sliding member 35. The rotating mechanism 4 includes a turntable 41, and the turntable 41 is arranged on the left side of the supporting column 22. A fixed block 42 is fixedly connected to the upper left side of the left fixed frame 21. A clamping block 43 is arranged on the left side of the fixed block 42. The turntable 41 is located between the clamping block 43 and the fixed block 42, and a handle 44 is arranged on the left side of the clamping block 43.

[0029] Based on the above features, the working principle of this embodiment is: the bolt is driven to rotate in the fixed block 42 by turning the handle 44, and at this time the handle 44 pushes the clamping block 43 toward the fixed block 42 until the clamping block 43 and the fixed block 42 clamp and fix the turntable 41. If the angle of the fence 1 needs to be adjusted, the handle 44 is turned to cancel the fixation of the turntable 41, and the turntable 41 is directly turned at this time. The turntable 41 drives the support column 22 to rotate, and the fence 1 rotates accordingly. When the fence 1 is adjusted to a suitable position, the handle 44 is turned again to fix the turntable 41, so that the placement of the fence 1 can be adjusted by adjusting the angle of the support column 22. When the fence 1 is not needed to block fish, the fence 1 can be adjusted to be horizontal with the ground to facilitate different fish to pass through the fishway. The sliding member 35 is a locking slider, and a top bolt is provided in the locking slider. A steel wire is fixedly wound around the sliding member 35, and the other end of the steel wire is provided on the fishway. When adjusting the gap of the fence 1, the steel wire is manually pulled, and the operating rod 351 is rotated by the steel wire, thereby canceling the braking of the sliding member 35, and pushing the adjusting column 33 to drive the sliding member 35 to slide on the sliding rod 34. The adjusting column 33 drives the fence 1 to move, so as to adjust the gap of the fence 1 by adjusting the length of the fence 1.
