Description

High-efficiency water inlet device for reservoir inlet

Technical Field

The utility model belongs to the technical field of flood control dispatch and specifically relates to a high-efficient water installations of reservoir import.

Background

The reservoir has the double functions of flood control and benefit. Some reservoirs have serious reservoir leakage because of relatively developed karst and interlaminar cracks and joint cracks at the positions. Although the reservoir does not influence the flood control function of the reservoir, the stored water of the reservoir leaks quickly, and the interest-promoting function of the reservoir cannot be realized. In order to better regulate the runoff of the reservoir, store flood and replenish depletion and enable natural incoming water to better meet the requirements of water use departments in terms of time and space, the reservoir generally needs to be completely impermeable at the reservoir bottom and the reservoir bank. However, since the reservoir is connected to the river, even if the reservoir is completely impermeable, water leaks from the upstream river. In order to prevent the leakage of the upstream river channel, an overflow dam is built at the connecting section of the river channel and the reservoir, so that the reservoir becomes a complete closed body, the leakage prevention of the water storage of the reservoir is guaranteed, and the improvement of the water storage benefit of the reservoir is very important.

Although the construction of the retaining dam at the inlet of the reservoir guarantees the integrity of the reservoir impermeable body and avoids excessive wet fermentation of the reservoir, the river in Shandong province is a river of a rain source type in a season wind area, the river water in the flood season of the river rises and falls suddenly and is cut off basically after flood, the blocking of the overflow dam enables the reservoir to enter water when the water level of the river is higher than the top of the overflow dam, namely, the reservoir can only enter water in the flood season, and small water in the river cannot enter the reservoir at ordinary times, so that certain influence is brought to the full utilization of water resources.

Detailed Description

The following detailed description is made on the efficient water inlet device for reservoir import according to the present invention with reference to the attached drawings.

As shown in fig. 1 to 4, the utility model discloses a high-efficient water installations of reservoir import, including upper reaches river course 1, low reaches reservoir 3 and overflow dam 2, overflow dam 2 is the step face towards the one side of low reaches reservoir, still includes the subassembly of intaking, and inside the overflow dam was evenly located to a plurality of subassemblies of intaking, the entrance point of the subassembly of intaking extended to the overflow dam outside and communicated with each other with the upper reaches river course, and the exit end of the subassembly of intaking extended to the overflow dam outside and communicated with each other with the low reaches reservoir, the exit end of the subassembly of intaking was equipped with check valve 5, and the entrance point of the subassembly of intaking is equipped with trash rack 8. The number of the water inlet assemblies is determined according to the length of the overflow dam.

The subassembly of intaking includes inlet tube 4, check valve 5, trash rack 8 and gate valve 11, the entrance point of inlet tube 4 is the loudspeaker form, and flange 9 installation trash rack 8 is passed through to the entrance point of loudspeaker form, but the import section of inlet tube is located to hand switch's gate valve 11, flange 9 installation check valve 5 is passed through to the exit end of inlet tube 4. The check valve 5 can be automatically opened under the pressure of water in the water inlet pipe, so that water in the upstream river channel can be discharged into the downstream reservoir 3, and the water in the downstream reservoir can be prevented from flowing back into the upstream river channel. When the water level in upper reaches river course is higher than reservoir water level 7, the water in the river course is arranged to the reservoir through inlet tube 4, through setting up the gate valve 11 at the inlet tube section of intaking, can realize the switch of inlet tube according to the on-the-spot particular case manual control gate valve.

In order to improve the application effect of the water inlet device, a water level sensor 10 capable of detecting the upstream river channel water level can be arranged on one side of an inlet section of the water inlet pipe, a flow velocity sensor 12 capable of detecting the water flow velocity of an inner cavity of the water inlet pipe is arranged on one side of an outlet section of the water inlet pipe, and the water level sensor 10 and the flow velocity sensor 12 are respectively connected with a controller. When water level sensor 10 detected that the water level in upper reaches river course 1 is less than the inlet tube, flow velocity sensor 12 detected that inlet tube outlet section has the velocity of flow, represented check valve 5 became invalid, and the water of low reaches reservoir passes through in inlet tube 4 backward flow advances the river course, and controller control alarm sent the warning this moment, and the suggestion water installations breaks down, and the artifical gate valve 11 that can manually close inlet tube inlet section overhauls water installations.

As shown in fig. 4, the check valve 5 includes a valve body 51, a valve plate 52 and a hinge 53, one end of the valve body 51 is connected with the water inlet pipe 4 through a flange and a sealing ring in a sealing manner, the other end of the valve body 51 is provided with the valve plate 52, and the valve plate 52 is hinged with the valve body 51 through the hinge 53. The valve plate 52 is opened around the hinge by the water pressure in the water inlet pipe 4, so that the opening state of the outlet of the water inlet pipe is realized, and the water in the upstream river channel is ensured to enter the reservoir through the water inlet pipe.

When the reservoir water level is lower than the river water level in the dry season, the check valve is opened by water pressure, and the reservoir enters water; when flood comes in flood season, the river water level speed rises, the river water level exceeds the dam crest, the reservoir simultaneously enters water through the dam crest and the water inlet pipe, the reservoir quickly reaches the saline-alkali water level, the river flood recedes, the river water level quickly drops, when the river water level is lower than the reservoir water level, the reservoir water pressure closes the check valve, and the reservoir reaches the condition that the stored water leaks from the upstream river; the reservoir water is continuously used for industrial water supply or agricultural irrigation after a flood, the reservoir water level is continuously reduced, when the reservoir water level is very low and water flows exist in a river channel, the check valve is opened by external pressure, and the reservoir can feed water. The check valve can be automatically opened and closed through the water level difference between the interior and the exterior of the reservoir, so that the labor is saved, and the opening and the closing are accurate and timely.

The foregoing is merely illustrative of some of the principles of the present invention and the description is not intended to limit the invention to the specific constructions and applications shown, so that all modifications and equivalents that may be utilized are within the scope of the invention.

Other technical features than those described in the specification are known to those skilled in the art.
