Description

TECHNICAL FIELD

[0001] The present application relates to mountainous rainwater collection technical field, specifically relates to a mountain torrent collection system. BACKGROUND

[0002] Mountain rainfall often forms mountain torrent along the mountain torrent and flows down, not only scouring the mountain, making the mountain rock exposed, but also easily forming mountain torrent, scouring the roadbed to form road surface collapse, or the rainwater mixed with sand and stone to form debris flow to harm traffic. At the same time, mountainous crop irrigation often lacks water, or needs to be diverted from a far away reservoir, which is time-consuming and laborious. In order to collect rainfall in mountainous areas, the rainfall is usually introduced to a nearby pond or reservoir for storage, which is large in engineering quantity and has more water loss along the way.

[0003] Therefore, a new mountain torrent collection system needs to be newly built, which can filter sand and branches and leaves in high-speed water flow, and also can collect and process the rainwater using the special topography of the mountain valley for crop irrigation. SUMMARY

[0035] Further: the rough filtering plate 110 is provided with a slag guide ditch 150 with a slope of 10°-45° along the gully 5, for the extra-large stones and dry branches and leaves filtered by the rough filtering plate 110 to fall into the slag guide ditch 150 by gravity, so as to facilitate the filtered extra-large stones and dry branches and leaves to flow to the bottom of the gully 5 through the slag guide ditch 150, so as to avoid the accumulation of the extra-large stones and dry branches and leaves at the rough filtering plate 110.

[0036] In addition, the filtering holes on the coarse filter plate 110 are provided with persimmon-shaped filter pockets 140, the maximum length of the persimmon-shaped filter pockets 140 is 6cm-10cm, the height is 4cm-6cm, and the persimmon-shaped filter pockets 140 are provided with circular holes with a diameter of 2mm-5mm, the length of the persimmon-shaped filter pockets 140 can control the sand and dry branches and leaves entering the persimmon-shaped filter pockets 140, the sand and dry branches and leaves with a length greater than the length of the persimmon-shaped filter pockets 140 are left on the coarse filter plate 110, and the rest enters the persimmon-shaped filter pockets 140, and the height of the persimmon-shaped filter pockets 140 limits the volume, if the size is too large, the difficulty of cleaning is large, if the size is too small, the persimmon-shaped filter pockets 140 are easily filled with sand, and the filtering effect is affected, therefore, the medium sand is retained in the persimmon-shaped filter pockets 140, and the fine sand and water flow through the persimmon-shaped filter pockets 140 and then flow to the sedimentation unit 2 through the gully 5.

[0038] Embodiment 4

[0039] As shown in Figure 1 , Figure 3 , Figure 5 This embodiment is a further improvement on the basis of any one of embodiments 1-3, and the specific improvements are as follows:

[0040] The sedimentation unit 2 comprises: an adjusting pool 210, the adjusting pool 210 is erected in the gully 5, the upper and lower ends of the adjusting pool 210 are open, a sand storage bin 220 is arranged below the adjusting pool 210 in the gully 5, the sand storage bin 220 is in communication with a sand outlet chute 230 arranged along the gully 5, a fine filter plate 240 is fixed in the opening at the lower end of the adjusting pool 210, the sand storage bin 220 and the adjusting pool 210 are separated by the fine filter plate 240, the fine sand in the water flow is filtered by the fine filter plate 240, the fine sand is retained in the lower sand storage bin 220, and the filtered clean water overflows into the adjusting pool 210 and is sent into the water storage unit 3 by the water guide unit 4.

[0041] The sand storage bin 220 is in a V shape, fully utilizes the V-shaped slope terrain of the gully 5, reduces the cross-section excavation, and at the same time, the sand is easy to deposit and collect in the V-shaped sand storage bin 220.

[0042] The thickness of the fine filter plate 240 is 2cm-5cm, and the fine filter plate 240 is provided with circular truncated cone-shaped filter holes 241, the lower hole diameter of the circular truncated cone-shaped filter holes 241 is 0.5mm-1.0mm, and the upper hole diameter is 0.25mm-0.5mm, the circular truncated cone-shaped filter holes 241 on the fine filter plate 240 are small at the top and large at the bottom, which not only can further filter the fine sand in the water, but also is convenient for later flushing.

[0043] In addition, the sand discharge trough 230 passes through the bottom of the water storage unit 3, which facilitates the discharge of sand and gravel in the sand storage bin 220 through the sand discharge trough 230 at the bottom of the water storage unit 3, reducing the workload of dredging.

[0044] Example 5

[0045] like Figure 5 As shown, this embodiment is a further improvement on embodiment 4, as detailed below:

[0046] The water guiding unit 4 includes: a guide pipe 410, one end of which extends into the regulating tank 210 through the tank wall, and the other end of which extends into the water storage unit 3.

The upper non-telescopic straight section of the telescopic pipe 420 is provided with a water inlet 421. The main function of the guide pipe 410 and the telescopic pipe 420 is to serve as a transport channel to transport rainwater from the regulating tank 210 to the water storage unit 3. The telescopic pipe 420 can extend and retract with the water level changes in the regulating tank 210. The float 430 can straighten the telescopic pipe 420 through buoyancy to ensure smooth water transport. The upper non-telescopic straight section of the telescopic pipe 420 is provided with a water inlet 421 to ensure that the incoming water is upper layer water and does not contain fine sand particles and floating impurities.

[0047] Because the gully 5 has a V-shaped slope, the size of the reservoir needs to be designed in conjunction with the gully 5. Therefore, the number of reservoirs needs to be determined based on the interception area of ​​the gully 5 and the historical maximum rainfall. In order to store as much rainwater as possible, the number of reservoirs in the water storage unit 3 can be one or multiple reservoirs assembled together. Depending on the ease of movement, the reservoirs can be fixed and transport water through pipelines, or they can be mobile, saving the work of laying and installing pipelines.

[0048] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
