Background technology
In the hydroelectric project having silt sedimentation requirement, the Prevention technology of water inlet silt mainly adopts following several mode: 1, by the layout of building, arranges rational tank silt volume, guarantees that silt elevation is lower than water inlet elevation within the runtime of power station; 2, by the mode of water inlet with the adjacent layout of power station outlet structure escape works, the washing away of current when utilizing sluicing flood passage, the discharge cleaning that pulling function carries out water inlet leading edge shoal materials; 3, special sand discharge building (desilting tunnel, flush gallery, bottom hole for sand flushing etc.) is utilized to carry out sand discharge; 4, the runner design of Appropriate application powerplant intakes and water diverting structure, by the washing away of diversion and power current, pulls, carries out the discharge allowing machine silt (referring generally to suspended load).
Due to factors such as the layout limitation of intake structure, the complexity of flow-shape and flow rate of water flow skewness, in above-mentioned silt Prevention technology, the local of water intaking building is often caused to there is unstable fluidised form or even Si Liu district, and then form the alluvial of suspended sediment, affect water intaking safety and the power benefit in power station.At present, the process of above-mentioned alluvial situation is generally adopted to the mode of artificial desilting when reservoir emptying or power station are shut down, not only time-consuming but also require great effort, affect benefit and the operational flexibility of power station or reservoir.
Had at present the mode arranging high-pressure water pipe in the side of building and rinse silt, the silt rinsed after digging is taken away by shell pump.Although the mode that high-pressure water pipe is rinsed solves above-mentioned Prevention technology mode Problems existing, but its shortcoming also existed is, the water under high pressure of the pipe end of cleaning hose can only rinse local silt, part silt also can remnants, therefore the continuous flushing of long period is needed, its efficiency is low, poor effect, urgently improves further.
Utility model content
The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, and provides a kind of silt remover of intake of hydropower station, structure is simple, sand discharge efficiency is high, effective feature that it has.
In order to solve the problem, the utility model adopts following scheme:
A kind of silt remover of intake of hydropower station, comprise the high-pressure water pipe be installed in water inlet building, the lower end of high-pressure water pipe is stretched out the side of water inlet building and piles towards water inlet silt, its upper end is connected with high-pressure water, the bottom of water inlet building is provided with sand discharge road, the front end in sand discharge road and silt are provided with shell pump between piling, the side of described high-pressure water pipe is connected with many distributive pipes, the end of described distributive pipe connects water diversion disk jointly, water diversion disk is with the collect cavity be communicated with distributive pipe, the soffit of water diversion disk is with multiple spray-hole of being communicated with collect cavity and be provided with the deflector being positioned at spray-hole side.
Further improvement as technique scheme:
Described water diversion disk is with the first dish portion and the second dish portion, and with angle between the first dish portion and the second dish portion, the second dish portion is tilted to lower setting relative to the first dish portion; Described distributive pipe comprises from the upper distributive pipe top to bottm arranged successively, middle distributive pipe and lower distributive pipe, and upper distributive pipe is communicated with the first dish portion, and middle distributive pipe and lower distributive pipe are communicated with the second dish portion respectively.
Technique effect of the present utility model is:
The utility model adopts water diversion disk structure, realization carries out continuous jet douche to the multiple directions of silt heap and multiple point, and rational distributive pipe is set ensures that water diversion disk each spray-hole has close expulsion pressure, thus the flush efficiency that effectively improve silt and effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, water inlet building; 2, high-pressure water; 3, high-pressure water pipe; 4, silt heap; 5, shell pump; 6, sand discharge road; 71, upper distributive pipe; 72, middle distributive pipe; 73, lower distributive pipe; 8, water diversion disk; 80, collect cavity; 81, the first dish portion; 82, the second dish portion; 83, spray-hole; 84, deflector.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, the silt remover of the intake of hydropower station of the present embodiment, comprise the high-pressure water pipe 3 be installed in water inlet building 1, the lower end of high-pressure water pipe 3 is stretched out the side of water inlet building 1 and piles 4 towards water inlet silt, its upper end is connected with high-pressure water 2, the bottom of water inlet building 1 is provided with sand discharge road 6, the front end in sand discharge road 6 and silt are provided with shell pump 5 between piling 4, the side of high-pressure water pipe 3 is connected with many distributive pipes, the end of distributive pipe connects water diversion disk 8 jointly, water diversion disk 8 is with the collect cavity 80 be communicated with distributive pipe, the soffit of water diversion disk 8 is with multiple spray-hole 83 of being communicated with collect cavity 80 and be provided with the deflector 84 being positioned at spray-hole 83 side.
Water diversion disk 8 is with the first dish portion 81 and the second dish portion 82, with angle between the first dish portion 81 and the second dish portion 82, relative first dish portion 81 of second dish portion 82 is tilted to lower setting, first dish portion 81 and the second dish portion 82 are arranged towards different directions, for changing the injection direction of current, improve the developing result to silt; Distributive pipe comprises from the upper distributive pipe 71 top to bottm arranged successively, middle distributive pipe 72 and lower distributive pipe 73, close in order to ensure the water flow jet pressure in the first dish portion 81 and the second dish portion 82, upper distributive pipe 71 is communicated with the first dish portion 81, and middle distributive pipe 72 and lower distributive pipe 73 are communicated with the second dish portion 82 respectively.
