[0003] In the current technology, flood control mechanisms are mainly based on spillways, which discharge floodwater through gates. Since most spillways now use a single gate to control the water flow velocity, it is difficult to effectively weaken the impact of strong floods. Utility Model Content

[0004] The purpose of this invention is to provide a flood control structure for water utilization, in order to solve the problem mentioned in the background art that most flood discharge channels nowadays control the water flow velocity with a single gate, which makes it difficult to effectively weaken the impact of floods when encountering strong floods.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a flood discharge mechanism, comprising a flood discharge frame, a first flood discharge channel, a second flood discharge channel, a third flood discharge channel, a first limiting slide, a spiral guide vane, a first mounting slot, a first locking slot, a second mounting slot, and a second locking slot. A gate mechanism is provided at the top of the flood discharge mechanism, comprising a gate frame, a second limiting slide, a threaded rod, a turntable, a gate plate, and a limiting slider. An obstruction mechanism is provided inside the flood discharge mechanism, comprising a mounting frame, an interception net, a first mounting block, and a second mounting block.

[0006] In a preferred embodiment, the flood discharge frame has a first flood discharge channel inside, a second flood discharge channel is provided on one side of the first flood discharge channel, a third flood discharge channel is provided on one side of the second flood discharge channel, and the first flood discharge channel is trapezoidal.

[0007] In a preferred embodiment, a first limiting groove is provided between the first flood discharge channel and the second flood discharge channel, as well as between the second flood discharge channel and the third flood discharge channel, and the inner bottom wall of the second flood discharge channel is fixedly connected to the bottom of the spiral guide vane.

[0008] In a preferred embodiment, the inner walls of the third flood discharge channel away from the second flood discharge channel are provided with first mounting grooves on both sides, and a first slot is provided on the bottom side of the first mounting groove. The inner walls of the third flood discharge channel away from the second flood discharge channel are provided with second mounting grooves on both sides, and a second slot is provided on the bottom side of the second mounting groove. The second mounting groove is located on one side of the first mounting groove.

[0009] In a preferred embodiment, the top of the flood discharge frame is fixedly connected to the bottom of the gate frame, the gate frame is provided in two sets, and the two sets of gate frames are respectively located at the top of the first limiting groove, and the inner walls of the gate frame are provided with second limiting grooves on both sides.

[0010] In a preferred embodiment, the top inner wall of the gate frame is threadedly connected to the outer wall of the threaded rod, the top of the threaded rod is fixedly connected to the bottom of the turntable, the bottom outer wall of the threaded rod is rotatably connected to the top inner wall of the gate plate through a bearing, both sides of the gate plate are fixedly connected to one side of the limiting slider, and the outer wall of the limiting slider is movably connected to the inner walls of the first limiting slide groove and the second limiting slide groove, respectively.

[0011] In a preferred embodiment, the inner wall of the third flood discharge channel is movably connected to the outer wall of the mounting frame, the inner wall of the mounting frame is fixedly connected to the outer wall of the interception net, both bottom sides of the mounting frame are fixedly connected to one side of the first mounting block, and both top sides of the mounting frame are fixedly connected to one side of the second mounting block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, water first enters the interior of the first flood discharge channel. The first set of turntables rotates, driving the threaded rod to rotate. The threaded rod connects to the top of the gate frame via a thread, causing the gate plate to move upwards. Simultaneously, the limiting slider moves along the inner walls of the first and second limiting grooves. The degree of upward movement of the gate plate controls the water flow velocity. Then, the water enters the interior of the second flood discharge channel and contacts the spiral guide vanes. The spiral guide vanes create a swirling flow as the water passes through, absorbing some of the impact force. The second set of turntables then rotates, driving the gate plate to move, thereby controlling the water flow velocity from the second to the third flood discharge channel. This three-stage stepped structure and the gate mechanism allow for graded control of the water flow velocity, reducing the impact force of floods. The spiral guide vanes further absorb some of the impact force.

[0015] 2. In this utility model, water flows into the interior of the third flood discharge channel, where it intercepts debris such as branches and stones carried by the flood through the mounting frame and interception net. When removing the debris, the mounting frame is moved as a whole towards the second flood discharge channel, so that the first mounting block and the second mounting block move from the interior of the first and second slots to the interior of the first and second mounting grooves, respectively. Then, the mounting frame is moved upward to remove it, which facilitates the interception of debris in the flood and the removal of the mounting frame, thus facilitating the cleaning of debris.

[0026] Specifically: through the three-stage stepped structure and the setting of gate mechanism 2, the water flow velocity is controlled in stages, reducing the impact force of floods. The setting of spiral guide vane 106 consumes part of the impact force.

[0027] In one embodiment, the top of the flood discharge frame 101 is fixedly connected to the bottom of the gate frame 201. Two sets of gate frames 201 are provided, and the two sets of gate frames 201 are respectively located at the top of the first limiting groove 105. The inner walls of the gate frame 201 are provided with second limiting grooves 202 on both sides. The top inner wall of the gate frame 201 is threadedly connected to the outer wall of the threaded rod 203. The top of the threaded rod 203 is fixedly connected to the bottom of the turntable 204. The bottom outer wall of the threaded rod 203 is rotatably connected to the top inner wall of the gate plate 205 through a bearing. Both sides of the gate plate 205 are fixedly connected to one side of the limiting slider 206. The outer wall of the limiting slider 206 is movably connected to the inner walls of the first limiting groove 105 and the second limiting groove 202, respectively.

[0028] Specifically: Rotating the first set of turntables 204 causes the threaded rod 203 to rotate. The threaded rod 203 is connected to the top of the gate frame 201 by a thread, which in turn causes the gate plate 205 to move upward. At the same time, the limiting slider 206 moves along the inner wall of the first limiting groove 105 and the second limiting groove 202. The water flow speed is controlled by the degree to which the gate plate 205 moves upward.

[0030] Specifically: the water flows into the interior of the third flood discharge channel 104, and then intercepts debris such as branches and stones carried by the flood through the mounting frame 301 and the interception net 302.

[0032] Specifically: the mounting bracket 301 is moved as a whole towards the direction of the second flood discharge channel 103, so that the first mounting block 303 and the second mounting block 304 are moved from the inside of the first slot 108 and the second slot 110 to the inside of the first mounting groove 107 and the second mounting groove 109 respectively. Then the mounting bracket 301 is moved upward to remove the mounting bracket 301.

[0033] Working principle: Water first enters the interior of the first flood discharge channel 102. The first set of turntables 204 rotates, driving the threaded rod 203 to rotate. The threaded rod 203 is connected to the top of the gate frame 201 via a thread, causing the gate plate 205 to move upwards. Simultaneously, the limiting slider 206 moves along the inner walls of the first limiting groove 105 and the second limiting groove 202. The degree of upward movement of the gate plate 205 controls the water flow velocity. Then, the water enters the interior of the second flood discharge channel 103, contacting the spiral guide vanes 106. The spiral guide vanes 106 create a swirling flow as the water passes through, absorbing some of the impact force. Then, the second set of turntables 204 rotates... 4. This causes the gate plate 205 to move, thereby controlling the water flow speed from the second flood discharge channel 103 to the third flood discharge channel 104. The water then enters the interior of the third flood discharge channel 104, where it intercepts debris such as branches and stones carried by the flood through the mounting frame 301 and the intercepting net 302. When removing the debris, the mounting frame 301 is moved as a whole towards the second flood discharge channel 103, so that the first mounting block 303 and the second mounting block 304 move from the interior of the first slot 108 and the second slot 110 to the interior of the first mounting groove 107 and the second mounting groove 109, respectively. Then, the mounting frame 301 is moved upward to remove it.
