Detailed Description
So that the manner in which the above recited objects, features and advantages of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments thereof which are illustrated in the appended drawings. It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
Some embodiments according to the invention are described below with reference to fig. 1 to 5.
As shown in fig. 1 and 2, the present invention provides a hydro-power generation system, comprising: the water wheel 1 is provided with at least 2 water storage areas along the axial direction of the water wheel 1; the water storage container 2 is provided with at least 2 water outlets, and the water outlets correspond to the water storage areas one by one; an execution unit; when the water quantity parameter of the water storage container 2 is larger than the opening threshold of any water storage area, the execution unit opens a water outlet corresponding to the water storage area; when the water quantity parameter of the water storage container 2 is smaller than the closing threshold of any water storage area, the execution unit closes the water outlet corresponding to the water storage area; the opening threshold of the water storage area with the smallest absolute value of the difference between the distances from the two sides of the water wheel 1 is smallest.
It can be understood that the water storage container 2 concentrates the water flow without pressure to improve the impact force of the water flow on the water wheel 1; the execution unit opens or closes the water outlet according to the water quantity parameter in the water storage container 2, so that on one hand, the water quantity in the water storage container 2 is kept in a certain range to keep the impact force of water power on the water wheel 1 vehicle, thereby realizing the effect of driving the water wheel 1, on the other hand, the water inflow of the water wheel 1 can be changed according to the flow change condition of the water area, and the utilization rate of the water area is improved; the setting is located the water storage district's of 1 axial midpoints of water wheels opening threshold value minimum to improve the rationality of 1 structure of water wheels.
It can be understood that, communicate water storage container 2 and waters, can be with the water in the waters introduce water storage container 2 in, water storage container 2's position can set up the position higher than waterwheel 1, because water storage container 2's position is higher than waterwheel 1, correspondingly, water in water storage container 2 has the more great gravitational potential energy than waterwheel 1, so be provided with and do benefit to the kinetic energy that turns into waterwheel 1 with the gravitational potential energy of water, improve the generating efficiency. The water outlet can be arranged on the side wall of the water storage container 2, and water in the water storage container 2 is introduced into the water storage area of the water wheel 1 through a water pipe to realize power generation; the water in the water storage container 2 can directly enter the water storage area of the water wheel 1 through the water outlet at the bottom of the water storage container 2. The water quantity parameter can be the water level in the water storage container 2, the water pressure at the bottom of the water storage container 2, and the flow entering the water storage container 2.
As shown in fig. 5, when the water wheel 1 is subjected to a force analysis, and a certain water storage area is subjected to impact F from water flow, the ratio of the force applied to the water wheel 1 at the two sides is
Wherein, m is this certain water storage district to the distance of waterwheel 1 one side, n is this certain water storage district to the distance of waterwheel 1 opposite side, be close to waterwheel 1 axial midpoint more promptly, when it receives water impact, the effort that produces waterwheel 1 both sides is more close, when the quantity in water storage district is when x (x 2k +1, k 2, 3, 4, … …), it opens the threshold value to have x to correspond, wherein, in all water storage districts, the threshold value of opening of the water storage district that is located waterwheel 1 axial midpoint is minimum, thereby avoid one side of waterwheel 1 because the atress is uneven to lead to grindingThe service life of the hydroelectric power generation system is effectively prolonged under the condition of damage; when the number of the water storage areas is y (y is 2k, k is 2, 3, 4, … …), there are y opening thresholds correspondingly, that is, the closer to the axial midpoint of the water wheel 1, the closer the acting force generated to the two sides of the water wheel 1 is when the water storage areas are impacted by water flow, and because the number of the water storage areas is even, the opening threshold of the water storage area arranged at the two sides closest to the axial midpoint of the water wheel 1 is the smallest, thereby avoiding the condition that one side of the water wheel 1 is worn due to uneven stress, and effectively prolonging the service life of the hydroelectric power generation system.
Specifically, for example, the first water outlet 201 and the second water outlet 202 are arranged in the water storage container 2, and the first water storage area 1001 and the second water storage area 1002 are arranged in the water wheel 1, a first opening threshold corresponding to the first water storage area 1001 is lower than a second opening threshold corresponding to the second water storage area 1002, a first closing threshold corresponding to the first water storage area 1001 is lower than a second closing threshold corresponding to the second water storage area 1002, the first opening threshold is greater than the first closing threshold, and the second opening threshold is greater than the second closing threshold. When the water in the water area flows into the water storage container 2, the water amount of the water storage container 2 is increased, and the water amount is increased to bring about the change of water amount parameters, in this case, taking a water level example, when the water amount in the water storage container 2 is increased but does not reach a first opening threshold, no water outlet is opened at this time, the water wheel 1 does not work, and the water level of the water storage container 2 starts to rise; when the water level reaches the first opening threshold, the execution unit opens the first water outlet 201, water in the water storage container 2 enters the first water storage area 1001 of the water wheel 1 through the first water outlet 201, the gravitational potential energy and the kinetic energy of the water flow are converted into the kinetic energy of the water wheel 1, and the water wheel 1 starts to rotate, so that power generation is realized. If the flow rate of the water flow entering the water storage container 2 is greater than the flow rate of the first water outlet 201, the water level of the water storage container 2 gradually rises to reach a second opening threshold value, at this time, the second water outlet 202 is opened, and the water in the water storage container 2 enters the first water storage area 1001 and the second water storage area 1002 in the water wheel 1 through the first water outlet 201 and the second water outlet 202 respectively. Due to the increase of the water outlet, the flow entering the water storage area of the water wheel 1 is increased. If the flow rate of the water flow entering the water storage container 2 is lower than the total flow rate of the water flowing out from the water outlet, the water level in the water storage container 2 starts to decrease, when the water level in the water storage container 2 decreases to a second closing threshold value, the second water outlet 202 is closed, the total flow rate of the water outlet is reduced, if the flow rate entering the water storage container 2 does not change, the water level starts to increase, and the process is repeated. It can be understood that the control of the water outlet can be realized only if the closing threshold corresponding to each water storage area is smaller than the opening threshold corresponding to the water storage area. The arrangement is such that the water level in the water storage container 2 is maintained at a certain height. From the perspective of energy conversion, when the water level in the water storage container 2 is maintained at a certain height, the water level of the water in the water storage container 2 is lowered in the process of entering the water wheel 1, which can be regarded as that the gravitational potential energy of the water far away from the bottom of the water storage container 2 is converted into the kinetic energy of the water at the water outlet, so that the lower the height of the water level is, the smaller the kinetic energy is. The arrangement of the first water outlet 201 and the second water outlet 202, and the above size arrangement of the opening threshold and the closing threshold corresponding to the first water outlet 201 and the second water outlet 202, make the water level in the water storage container 2 always maintain in a certain height range, and make the water flow rate flowing out from all the water outlets relatively stable, i.e. the speed of the water wheel 1 converting kinetic energy into electric energy relatively stable, which is beneficial to the subsequent rectification of electric energy.
In the above embodiment, a third water outlet 203 may be further provided, and the third opening threshold is greater than the second opening threshold, the third closing threshold is greater than the second closing threshold, and the third opening threshold is greater than the third closing threshold, so as to adapt to the complex change of the flow rate of the water area. Since the flow rate change of the river is often influenced by the weather, and a great change occurs in a short time range, such a large flow rate change cannot be accommodated only by the first water outlet 201 and the second water outlet 202, the third water outlet 203 is provided to increase the accommodation range of the hydro-power generation system. Wherein, owing to be provided with 3 delivery ports, water wheels 1 also divides into 3 water storage districts in the axial, wherein, water wheels 1 generally fixes it through the support to its both sides, the rotation of water wheels is also convenient for to such fixed mode, because the first threshold value of opening that first water storage district 1001 corresponds is minimum, so often keep the state of opening, set up second water storage district 1002 and third water storage district 1003 in the both sides of first water storage district 1001, make the power that receives of water wheels 1 both sides keep unanimous as far as possible, avoid one side of water wheels 1 because the uneven condition that leads to wearing and tearing of atress, effectively prolong hydroelectric power generation system's life.
Optionally, the water storage area can be symmetrically distributed along the axial midpoint of the water wheel 1. For making the effort that the waterwheel 1 both sides received close, the water storage district more than 2 sets up to be the symmetric distribution along 1 axial midpoint both sides of waterwheel to avoid one side of waterwheel 1 because the uneven condition that leads to wearing and tearing of atress, effectively prolong hydroelectric generation system's life.
As shown in fig. 3 and 4, in the above embodiment, the water storage region is provided with the vanes 101, the vanes 101 divide the water storage region into more than 2 water hoppers 102, and the vanes 101 of adjacent water storage regions may also be arranged in a staggered manner. The arrangement of the water bucket 102 can enable the water impacting the water wheel 1 to still stay in the water bucket 102, and the gravitational potential energy of the water is further converted into the kinetic energy of the water wheel 1 in the rotating process of the water wheel 1, so that the power generation efficiency is improved. Because a plurality of water storage areas are formed in the water wheel 1 along the axial direction, the water storage areas mainly play a role in bearing water flow, so that the kinetic energy and the gravitational potential energy of the water flow can be converted into the kinetic energy of the water wheel 1. It will be understood that the flow rate of the water flow is constant over a certain period of time, and when the blades 101 start to receive the impact from the water flow, since the blades 101 are always in motion, the impact surface with the water flow is not always constant, i.e. the energy conversion rate of the water flow is variable, which means that when the blades 101 are in motion close to the water outlet, the conversion amount is larger, and when the blades 101 receive the impact far from the water outlet, the conversion amount is smaller, the water flow impacts the blades 101 in the water storage area, and the blades 101 are arranged in a staggered manner, so that the blades 101 always receive the impact from the water flow at the position close to the water outlet without increasing the number of the blades 101, on one hand, the rotation rate of the water wheel 1 body is maintained in a stable interval, and on the other hand, the stable rate makes the operation of the water wheel 1 smoother and more stable.
In one embodiment, the first opening threshold is set to be 5 meters, the second opening threshold is set to be 8 meters, the third opening threshold is set to be 10 meters, the first closing threshold is set to be 3 meters, the second closing threshold is set to be 5 meters, the third closing threshold is set to be 8 meters, and the work flow of the hydroelectric power generation system in the rainstorm period is as follows: the water level in the water storage container 2 begins to increase along with the continuous rainstorm, when the water level reaches 5 meters, the first water outlet 201 is opened, water flows into the first water storage area 1001 through the first water outlet 201, the water wheel 1 is driven to rotate, and the water level continuously rises due to the fact that the flow of a river is larger than that of the first water outlet 201 during the rainstorm; when the water level reaches 8 meters, the second water outlet 202 is opened, water flows through the first water outlet 201 and the second water outlet 202 to enter the first water storage area 1001 and the second water storage area 1002 respectively, the flow rate of the water outlet is increased but is still smaller than the flow rate of a river flowing into the water storage container 2, and the water level in the water storage container 2 continuously rises; when the water level reaches 10 meters, the third water outlet 203 is opened, water flows also enter the third water storage area 1003 through the third water outlet 203, at the moment, the total flow of the water outlets is basically equal to the flow of river flow entering the water storage container 2, and the water level change is not obvious. After rainstorm, the flow of the river is reduced and is smaller than the total flow of the water outlet, and the water level in the water storage container 2 begins to drop; when the water level drops to 8 meters, the third water outlet 203 is closed, the total flow of the water outlet is reduced and still larger than the flow of the river flowing into the water storage container 2, and the water level continuously drops; when the water level drops to 5 meters, the second water outlet 202 is closed, the total flow of the water outlet is reduced, but the water level still drops; when the water level is reduced to 3 meters, the first water outlet 201 is closed, the water wheel 1 loses the driving source, the rotation is suspended, the water storage container 2 starts to store water until the water level is increased to 5 meters, and the process is repeated.
