Description

合口式水浪发电机Combined water wave generator 技术领域Technical field

背景技术Background technique
已有的波浪发电技术是采用在浮力筒四周安装叶片，让波浪冲击叶片下部，叶片在波浪冲击下转动，带动与浮力筒相连的发电机进行转动发电。由于波浪会随着外部天气变化发生变化，有时高，有时低，当波浪不仅打在叶片下面，同时也打在叶片上方，这样，叶片所获得转动力矩变小，使得发电机吸收能量也相应变小，发电效率相应降低，因而现有波浪发电技术只能吸收少量波浪的能量，而没有对大量波浪加以利用。The existing wave power generation technology adopts the installation of blades around the buoyancy cylinder, so that the waves impact the lower part of the blade, and the blades rotate under the impact of the waves, and the generator connected to the buoyancy cylinder is driven to generate electricity. Since the waves change with the change of the external weather, sometimes high and sometimes low, when the waves are not only hit under the blades, but also hit above the blades, so that the rotational torque obtained by the blades becomes smaller, so that the energy absorbed by the generator also changes accordingly. Small, the power generation efficiency is correspondingly reduced, so the existing wave power generation technology can only absorb a small amount of wave energy, and does not utilize a large amount of waves.

本发明合口式水浪发电机的工作原理为：本发明合口前端进水口处横截面积大，后端直口连接处出水的横截面积小，因而能将进水口处大量低速的波浪收集到出口很小的合口尾部；由于合口的出口很小，因而其水流速度将会加快，合口末端高速水流经直口冲击与发电机的输入轴连接的叶片轴的叶片，将使发电机获得很大的能量。The working principle of the combined water wave generator of the invention is as follows: the cross-sectional area of the front inlet of the combined mouth of the invention is large, and the cross-sectional area of the outlet at the back end straight connection is small, so that a large number of low-speed waves at the water inlet can be collected. The tail of the joint is very small; because the outlet of the joint is small, the water flow speed will be accelerated, and the high-speed water at the end of the joint will flow through the blade of the blade shaft connected to the input shaft of the generator through the straight mouth, which will make the generator very large. energy of.
由于本发明的合口可以做得足够大，因而可以将大量的海水波浪能收集起来发电，且合口的出水口横截面积小，具有提升波浪速度的作用，因而也可以将其它水面的相对较小的水波浪能收集起来发电。由于海浪无需成本，持续时间长，源源不断，使得本发明发电机可持续发电。另外，本发明在直口前端设置闸门，避免了过大海浪对发电机的损坏，使本发明的安全性能优越。本发明在合口的进水口设置立柱和去渣结构，使得较大杂物不能进入进水口，且还能对进水口进行清理，既可以隔离杂物，又可以防止杂物堵塞合口的进水口。本发明也可用于其它水域中的波浪发电。Since the joint of the present invention can be made large enough, a large amount of seawater waves can be collected to generate electricity, and the joint outlet has a small cross-sectional area and has the function of increasing the wave speed, so that other water surfaces can be relatively small. The water waves can be collected to generate electricity. Since the waves do not require cost, the duration is long, and the source is continuous, the generator of the present invention can sustain power generation. In addition, the present invention provides a gate at the front end of the straight mouth to avoid damage to the generator caused by excessive sea waves, and the safety performance of the present invention is superior. The invention provides a column and a slag-removing structure at the water inlet of the joint, so that the larger debris can not enter the water inlet, and the water inlet can be cleaned, which can not only isolate the foreign matter, but also prevent the debris from blocking the water inlet of the joint. The invention is also applicable to wave power generation in other waters.

The genset 1 includes a generator 11, a coupling 12, a vane 13, a vane shaft 14, a bearing housing 15, and a nut 16, wherein the vane 13 is fixedly mounted on the vane shaft 14, and the bottom of the vane shaft 14 is locked by a nut 16, and The vane 13 is disposed at the output end of the joint portion 2 (the tail portion of the straight port 23), the vane shaft 14 and the input shaft of the generator 11 are connected and fixed by the coupling 12, and the output end of the vane shaft 14 is provided with two bearing seats 15, two The bearing housing 15 is fixed to the support post 231 of the joint portion 1. The joint portion 2 includes a joint 21, a pillar 22 and a straight mouth 23, and the plurality of pillars 22 are plural, and one end of the plurality of pillars 22 is fixedly disposed in the water, and the other end is supported at a support portion of the joint 21 or a support portion of the straight mouth 23, The tail of the joint 21 is integrally connected with the inlet of the straight mouth 23 (as shown by the hole P of the joint 21 entering the straight mouth 23 in FIG. 2), and the inlet end of the joint 21 is provided with an open water inlet, and the water inlet is disposed at In the water, the opening area of the water inlet is large, but the tail outlet area associated with the straight mouth 23 is small, that is, the cross-sectional area from the open end to the tail end of the joint 21 is gradually reduced, and the joint 21 is integrally disposed in the water, so that the straight mouth 23 is connected to the joint 21 in the water, the tail of the straight mouth 23 protrudes from the water surface, and the blade 13 is provided at the tail opening of the straight mouth 23, and the blade shaft 14 is disposed at a position flush with one side of the straight mouth 23, and the tail of the straight mouth 23 A support column 231 is also provided vertically, and the generator 11 and the vane shaft 14 are fixed to the support post 231 by bolts 24.
当水从合口21的进水口进入合口21后，从合口尾部进入直口23，再从直口23尾部的开口处出来。在此过程中，由于合口21的进水口的过水面积比较大，中间逐渐收小，直至合口21的尾部，使合口尾部的过水面积最小；当比较慢速的水进入合口21的进水口，由于进水口面积大，所以，在流量一定情况下，由于合口21尾部的出口面积(过水面积)比较小，使合口21尾部出口水的流速加大，即水流以高速进入直口23，由于直口23从头至尾的口径不变，因而这些快速流动的水直接冲击直口出口处的叶片13，叶片13带动叶片轴14转动从而带动发电机11的输入轴转动实现发电。When the water enters the joint 21 from the water inlet of the joint 21, it enters the straight mouth 23 from the tail of the joint, and then comes out from the opening of the tail of the straight mouth 23. In this process, since the water inlet area of the water inlet of the joint 21 is relatively large, the middle gradually shrinks until the tail of the joint 21, so that the water passing area of the tail of the joint is minimized; when the slow water enters the water inlet of the joint 21 Since the inlet area is large, in the case of a certain flow rate, since the outlet area (water passing area) of the tail portion of the joint 21 is relatively small, the flow rate of the outlet water at the end of the joint 21 is increased, that is, the water flow enters the straight port 23 at a high speed. Since the diameter of the straight mouth 23 from the beginning to the end is constant, these fast flowing water directly impacts the blade 13 at the outlet of the straight port, and the blade 13 drives the blade shaft 14 to rotate to drive the input shaft of the generator 11 to generate electricity.
本发明合口式水浪发电机第二实施例如图4、图5所示，它与第一实施例不同之处在于：在合口21的尾部连接两个直口23，两个直口23的出口处分别安装用于保证安全的闸门3，闸门3上连接有液压油缸31的活塞杆，该液压油缸31的底部固定在直口23上。一直口23的出口处设置叶片13，且后面设置有叶片13的闸门3一般处于常开，而没有设置叶片13的闸门3一般处于常闭状态。。在外部水的流速比较大时，有一定压力的水进入直口23，发电机11超负荷运转时，启动液压油缸31，顶起常闭的闸门3，使合口21中的水同时从常闭闸门3的打开处流出，同时启动另一常开闸门3的液压油缸31，使常开闸门3开得小些，使装载有叶片13的直口23的水压减轻，从而保证发电机11的正常运转，实现正常发电。The second embodiment of the combined water wave generator of the present invention is shown in FIG. 4 and FIG. 5, which is different from the first embodiment in that two straight ports 23 and two straight ports 23 are connected at the tail of the joint 21.

When the generator 11 is overloaded, the hydraulic cylinder 31 is activated to lift the normally closed gate 3, so that the water in the joint 21 is simultaneously closed. The opening of the gate 3 flows out, and at the same time, the hydraulic cylinder 31 of the other normally open gate 3 is activated, so that the normally open gate 3 is opened smaller, the water pressure of the straight port 23 loaded with the vane 13 is reduced, thereby ensuring the generator 11 Normal operation to achieve normal power generation.

A hydraulic sump 31 is installed between the tops of 21. When the water flow rate entering the port 21 is fast, in order not to damage the generator due to overload, the gate 3 can be raised by the hydraulic cylinder 31, so that the amount of water entering the port 21 is reduced, so that the water flow rate into the straight port 23 is not reached. It will be too fast to protect the generator 11 from damage.
