[0022] In one embodiment, Figure 1-6 As shown, the water conservancy drainage flood discharge channel includes a flood discharge channel body 1, and baffles 2 are fixedly connected to the left and right sides of the inner wall of the flood discharge channel body 1 and near the front side. A filter screen plate 3 is provided near the front side of the inner cavity of the flood discharge channel body 1, and the filter screen plate 3 is arranged on the front side of the baffle 2. The front sides of the two baffles 2 are respectively fitted with the left and right sides of the rear front side of the filter screen plate 3. The left and right sides of the inner wall of the flood discharge channel body 1 and near the front side are fixedly connected to the protective frame 4, and the protective frame 4 is arranged on the front and rear sides of the filter screen plate 3. A fixing mechanism is arranged in the protective frame 4, and the fixing mechanism includes a first screw 5, and the first screw The front and rear end surfaces of 5 are respectively connected to the front and rear sides of the inner wall of the protection frame 4 by bearings, the rear end of each first screw 5 surface is connected to a connecting plate 6 by bearings, the top and bottom of the rear side of each connecting plate 6 are fixedly connected to a connecting rod 7, the front ends of the upper and lower connecting rods 7 are respectively movably sleeved on the top and bottom of the rear side of the protection frame 4 and penetrate to the outside of the rear side of the protection frame 4, the rear side of each connecting rod 7 is fixedly connected to a limiting plate 8, the rear side of the limiting plate 8 is fitted with the front side of the filter screen plate 3, and the left and right sides of the inner wall of the flood discharge channel body 1 and near the rear side are fixedly connected with a buffer plate 9.

[0023] In order to be able to drive the first screw 5 to rotate outside the protective frame 4, a spur gear 10 is fixedly sleeved on the front end of the surface of the first screw 5, and a connecting block 11 is fixedly connected to the rear side of the inner wall of the protective frame 4 and near the top, and a second screw 12 is threadedly sleeved on the middle part of the connecting block 11, and a fixed block 13 is connected to the lower end bearing of the second screw 12, and a rack 14 is fixedly connected to the bottom surface of the fixed block 13, and the rack 14 and the spur gear 10 are arranged opposite to each other on the left and right, and the rack 14 is meshed with the spur gear 10.

[0024] In order to facilitate the driving of the second screw 12 to rotate outside the protective frame 4, the upper end face of the second screw 12 is fixedly connected with a rotating rod 15, and a through hole is opened at the top of the protective frame 4. The upper end of the rotating rod 15 is movably sleeved in the through hole and passes through to the outside of the top of the protective frame 4, and the upper end face of the rotating rod 15 is fixedly connected with a handle.

[0025] In order to limit the rack 14 and prevent it from rotating with the second screw 12, the bottom surface of the rack 14 is fixedly connected to a guide rod 16, and the lower end of the guide rod 16 is movably sleeved with a sleeve 17, and the bottom surface of the sleeve 17 is fixedly connected to the bottom surface of the inner wall of the protective frame 4.

[0026] In order to buffer the flood entering the flood discharge channel body 1, the buffer plate 9 is arranged obliquely. There are a plurality of buffer plates 9, and the plurality of buffer plates 9 are distributed in an interlaced manner.

[0027] In order to clamp and fix the filter screen plate 3 from both the left and right sides of the upper and lower sides, thereby improving the stability of the clamping of the filter screen plate 3, the number of limit plates 8 is four, and two limit plates 8 facing each other above and below form a group. The rear sides of the two groups of limit plates 8 are respectively fitted with the front side of the filter screen plate 3 and close to the left and right sides, and each group of two limit plates 8 are respectively fitted with the front side of the filter screen plate 3 and close to the top and bottom.

[0028] Working principle: When the utility model is used, the rotating rod 15 is twisted, and the rotating rod 15 drives the second screw 12 to rotate. The second screw 12 rotates to move upward, and the second screw 12 drives the fixed block 13 to rise, and the fixed block 13 drives the rack 14 to rise. The rise of the rack 14 drives the spur gear 10 to rotate, and the spur gear 10 drives the first screw 5 to rotate. The rotation of the first screw 5 makes it move forward in the protective frame 4, and the connecting plate 6 drives the connecting rod 7 to move forward. The connecting rod 7 drives the limiting plate 8 to move forward, so that the rear side of the limiting plate 8 is no longer in contact with the front side of the filter screen plate 3, and the clamping of the filter screen plate 3 is released. At this time, the filter screen plate 3 can be taken out from the flood discharge channel body 1. In this way, the filter screen plate 3 can be installed and removed. The mechanism is arranged inside the protective frame 4, and the connecting rod 7 and the limit plate 8 arranged outside the protective frame 4 are fixedly connected in a more stable manner, thereby preventing the mechanism for fixing the filter screen plate 3 from being damaged due to the impact of hard garbage in the water, resulting in the subsequent inability to disassemble the filter screen plate 3 or the loosening of the fixation of the filter screen plate 3, thereby improving the service life of the device and the stability of the fixation of the filter screen plate 3. When disassembling and assembling the filter screen plate 3, since the rack 14 is close to the top of the flood discharge channel body 1, the operator can squat above the flood discharge channel body 1 and extend his arm into the flood discharge channel body 1 to operate the limit plate 8 to move forward and backward, without the operator having to put his upper body or the entire body into the flood discharge channel body 1, and the operation is easier.

[0029] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
