Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-5 The utility model provides an embodiment: a rapid flow trough for water conservancy projects, including a first trough body 1, a second trough body 7 is arranged on one side of the first trough body 1, an extension plate 6 is arranged on one side of the first trough body 1 and a side wall of the second trough body 7, and an insert block 10 is arranged on one side of the lower end surface of the two extension plates 6, and a groove 4 is opened on the inner side wall of the other end of the first trough body 1 and the inner side wall of the other end of the second trough body 7, and a card slot 3 is arranged on one side of the lower inner wall of the two grooves 4, and the first trough body 1 is conveniently installed on one side of the second trough body 7 by inserting the insert block 10 into the card slot 3, and the first trough body 1 and the second trough body 7 can also be improved by the cooperation of the insert block 10 and the card slot 3. The connectivity between the two bodies 7 is improved to improve the impact resistance. Steps 9 are provided at the front and rear ends of the lower inner walls of the first trough body 1 and the second trough body 7. A plurality of circulation structures 2 are arranged horizontally at the center of the rear end surface of the step 9 at the front of the first trough body 1 and the center of the front end surface of the step 9 at the rear of the first trough body 1. A leakage hole 8 is provided at one side of the center of the lower inner wall of the first trough body 1. A gathering structure 5 is provided at the rear end of the first trough body 1. The circulation structure 2 is used to slow down the overall water flow speed. When the water flow is slow, the silt is easy to settle and enters the gathering structure 5 through the leakage hole 8 to accumulate, thereby preventing the silt from accumulating inside the first trough body 1 and the second trough body 7 and affecting the use.

[0032] The circulation structure 2 includes an annular groove 201 and a guide groove 202. The guide groove 202 is obliquely arranged on one end face of the step 9, and the annular groove 201 is arranged on the output end of the guide groove 202. The other end of the annular groove 201 passes through the step 9 and reaches the end face of the step 9. The water flows along the guide groove 202 into the annular groove 201 for diversion. The diverted water flow is then transported in the direction of the countercurrent through the output end of the annular groove 201 to buffer the main water flow, thereby facilitating the slowing down of the overall speed of the water flow.

[0033] The gathering structure 5 includes a storage tank 501 and a connecting pipe 503. The storage tank 501 is arranged at one side of the rear end of the first tank body 1, and the connecting pipe 503 is arranged at the lower center of the front end surface of the storage tank 501. The other end of the connecting pipe 503 is fixedly connected to the lower end of the leakage hole 8. The mud and sand enter the connecting pipe 503 through the leakage hole 8, and then enter the storage tank 501 through the connecting pipe 503 for storage. An opening is provided at the upper part of one side wall of the storage tank 501, and a staircase 502 is provided inside the opening. The accumulated mud and sand can be cleaned up by going down to the storage tank 501 through the staircase 502.

[0034] A grid 11 is provided at the upper part of the leakage hole 8 to prevent animals or pedestrians from falling into the leakage hole 8 and being accidentally injured. The plug block 10 on the lower end surface of the extension plate 6 on one side of the first trough body 1 is slidably connected to the inside of the inner wall slot 3 of the groove 4 on the side of the second trough body 7, so that the first trough body 1 can be conveniently installed at one end of the second trough body 7. Multiple circulation structures 2 at the front and multiple circulation structures 2 at the back are cross-arranged, so that the water flow can be evenly buffered by the multiple circulation structures 2.

[0035] Working principle: During installation, dig a ditch on the ground first, install the second trough body 7 into the ditch, then place the first trough body 1 into the ditch at the rear end of the second trough body 7, place the extension plate 6 at the front end of the first trough body 1 in contact with the groove 4 at the rear end of the second trough body 7, insert the plug 10 at the lower end of the extension plate 6 into the card slot 3 inside the groove 4, install the first trough body 1 at the rear end of the second trough body 7, and insert the plug 10 into the card slot 3, which is convenient for installation and can prevent excessive impact force from breaking the first trough body 1 and the second trough body 7 apart, thereby improving safety in use. Safety: when water flows into the space between the two steps 9 inside the first tank body 1, a small part of the water flow moves into the guide groove 202 on the side wall of the two steps 9, and then the water is output against the water flow through the annular groove 201. The water flow slows down after the impact of the countercurrent water, reducing the wear and tear on the first tank body 1 and the second tank body 7 and related facilities, and extending the service life. When the water flow is too large and overflows the two steps 9, the water flow at the upper ends of the two steps 9 flows normally, and the water flow between the two steps 9 slows down to prevent the occurrence of large water flow that cannot flow quickly.

[0036] When the water flows between the two steps 9 inside the first tank body 1, the speed slows down, and the mud and sand in the water are easy to settle, enter the leakage hole 8 through the grid 11 holes, and then roll into the storage tank 501 through the connecting pipe 503. The height of the storage tank 501 is higher than the first tank body 1 and the second tank body 7. There is no need to worry about water overflowing through the storage tank 501, and the mud and sand can be collected to prevent the mud and sand from accumulating at the bottom of the first tank body 1 and the second tank body 7, which is inconvenient to clean.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
