Description
Technical Field
The invention relates to a device for large variation of reservoir water level, intercepting dirt, and ensuring flood discharge and power generation safety.
Background
When the reservoir is built in the area with uneven runoff, the reservoir water level is usually large in amplitude, and when more dirt comes from the upstream of the reservoir, a dirt blocking device is usually required to be arranged. The general existence of floaters has potential safety hazards to engineering operation, and the influence of the floaters on a power generation and water diversion system is particularly serious. A water diversion water inlet of a power station is generally provided with a trash rack for intercepting floating dirt in a reservoir area, but the trash rack is often blocked due to large amount of the dirt, so that a water head is reduced and the output of a unit is reduced, thereby influencing the power generation benefit; the trash rack structure can be damaged if the weight is heavy, and the operation safety of the unit is endangered if the weight is heavy. The shutdown maintenance of the trash rack or the cleaning of the hydropower station is troublesome work which is labor-consuming and time-consuming. In practical engineering, most hydropower stations are provided with a trash rack at a water inlet and a trash rack facility at the front edge of the water inlet.
For the power generation diversion system, the arrangement of the trash blocking device has the following practical benefits:
1. the water head benefit is improved, the water head of about 0.3m can be improved by adopting the inlet and tail water pressure difference meter for comparison and calculation.
2. The machine is free from shutdown and load reduction pollution cleaning loss, a pollution blocking device is not used, the machine is completely shutdown for 3-5 times due to too much garbage at a water inlet of the machine set every year, and the loss can be avoided after the floating blocking device is installed.
3. The benefits generated by the downtime during flood are reduced, and the downtime caused by flood is reduced, so that the generated energy is improved.
4. The efficiency of the safe operation of the unit, after the trash blocking device is installed, the vibration of the unit is reduced because no garbage enters the flow channel of the unit, the cooling water of the unit is free of blocking phenomenon, the temperature is reduced, and the long-period safe and stable operation of the unit is effectively guaranteed.
5. Comprehensive benefits, after the trash blocking device is installed, foreign garbage at the water inlet of the machine set runner is reduced, the trash cleaning amount of the trash rack at the water inlet of the machine set runner is greatly reduced, the large investment of manpower and material resources in trash cleaning work in the flood season is reduced, and secondary pollution of land and urban roads caused by garbage transfer is avoided.
The main function of the trash holding device is to hold up the trash, the external load acting on the float retaining cable is mainly the action of water flow force, and the size of the water flow force depends on the flow velocity of the water flow and the water blocking area of the float retaining cable. Therefore, the calculation formula is needed when the structure of the cable is designed as follows:
Q＝μeB×(2gh0-h1)0.5
q＝0.5×r×(HS 2-Hx 2)
FP＝qL2/8f
the traditional trash blocking device is characterized in that a floating barrel on water is adopted, the water blocking area of the floating barrel on the water surface is large frequently, large horizontal tension is caused, the size of the anchor pier on two sides is large, especially when the water level amplitude is large, the engineering quantity is large, the investment is large, and the construction difficulty is large. It is therefore desirable to have new trash holding devices that avoid the above problems.
