[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figures 1 to 3 , a water conservancy engineering diversion device, comprising: a first slow flow part, the first slow flow part is used to filter foreign matter in the water and block stones before the second slow flow part;

[0033] The second slow flow part is used to slow down the flow rate of water;

[0034] One end of the second slow flow portion is connected to the first slow flow portion, and the other end of the second slow flow portion is connected to the drain pipe 8;

[0035] The first slow flow part comprises: a drainage channel 1 and a buffer component;

[0036] One end of the drainage channel 1 is arranged through one end of the second slow flow portion;

[0037] The bottom of the drainage channel 1 is provided with a protrusion 2 for blocking large rocks;

[0038] The buffer component is connected to one end of the drainage channel 1 and is used to filter foreign matter and mixed stones in the water. When the stones come into contact with the buffer component, the buffer component undergoes elastic deformation.

[0039] The buffer component is located in the second buffer portion.

[0040] The inventive point of the present application is that water is introduced into the first buffer part through the provided drainage channel. When the water flows through the drainage channel, the protrusion blocks the large stones. When the small stones mixed in the water come into contact with the buffer component, the buffer component undergoes elastic deformation. While blocking the stones, the damage to the buffer component by the stones is effectively reduced. At the same time, the buffer component can filter foreign matter and small stones in the water.

[0041] In some embodiments, the protrusions 2 are arranged at intervals, and the protrusions 2 are long strip structures. The heights of the protrusions 2 increase in sequence, and the protrusions close to the buffer component are the highest.

[0042] The bottom of the drainage channel 1 is in a slope structure, and the highest point of the slope is arranged close to the buffer component.

[0043] Among them, setting the bottom of the drainage channel as a slope structure can slow down the flow rate of water, making it easier to block large stones and most of the stones between the protrusions.

[0044] In some embodiments, the buffer assembly includes: a filter plate 3, a side plate 4 and a spring 5;

[0045] The side plates 4 are provided on both sides of the diversion channel 1 in the second slow flow portion;

[0046] The filter plate 3 is located between the side plates 4, and a flange is provided on one side of the side plate 4;

[0047] A through hole is provided on the flange, and a connecting rod is provided on one side surface of the filter plate 3 . The connecting rod passes through the through hole, and a spring 5 is sleeved on the connecting rod between the flange and the filter plate 3 .

[0048] When small stones in the water come into contact with the filter plate, the extension of the connecting rod through the through hole increases, the filter plate approaches the flange, the spring is compressed, and the force of the stone is effectively buffered. The filter plate can both block the stone and filter the water.

[0049] In some embodiments, an arc-shaped slide groove is provided on the side plate 4 , and a limiting member passing through the slide groove is provided on the side of the drainage channel 1 .

[0050] The function of the chute is to adjust the elevation angle of the side plate according to the flow rate and size of the water flow, so as to change the contact angle between the stones in the water and the filter plate. For example, if the angle between the filter plate and the direction of the water flow is adjusted from 30° to 90°, it will be difficult for the stones to pass over the filter plate, thereby increasing the blocking effect of the filter plate on the stones.

[0051] The limiting piece is a fastening screw. When adjusting the angle of the filter plate, the fastening screw can be loosened, and then the angle of the filter plate is adjusted to the required angle, and then the fastening screw is tightened. The diameter of the fastening screw is smaller than the width of the slide groove. When the fastening screw is tightened, the gasket set on the fastening screw is used to press the filter plate to death, thereby realizing the position limitation of the filter plate.

[0052] In some embodiments, the second slow flow section includes: a slow flow box 6 and a slow flow plate 7;

[0053] One side of the slow flow box 6 is connected to the filter channel, and the other side of the slow flow box 6 is connected to the drain pipe 8;

[0054] The slow flow plate 7 is wavy in shape, and the setting direction of the slow flow plate is adapted to the direction of the water flow. A plurality of slow flow plates 7 are provided, and the slow flow plates 7 are connected to the bottom of the slow flow box 6 .

[0055] Among them, the function of the slow flow plate is to change the flow rate of water, making the water move relatively slowly, thereby reducing the pressure in the drain pipe.

[0056] In some embodiments, the drain pipe 8 is provided in plurality, a base is provided at the bottom of the drain pipe 8, a bracket is provided at the top of the base, and an electric cylinder 9 is provided on the bracket;

[0057] A gate plate 10 is arranged in the slow flow box 6 , and the gate plate 10 is arranged close to the drain pipe 8 . A filter hole is arranged on the gate plate 10 , and the top of the gate plate 10 is connected to the output end of the electric cylinder 9 .

[0058] Among them, the function of the gate is to be used in situations where there are many foreign objects in the water and in environments where the water flow is relatively turbulent.

[0059] When there are many foreign objects in the water, the filtering effect may not be obvious when relying on the filter plate. At this time, the gate plate can be lowered to filter the water for the second time to prevent foreign objects from clogging the drain pipe. When the water flow is turbulent, the water outlet pressure of the drain pipe can be reduced through the gate plate below.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
