Background technique

The maturation method that utilizes tidal power generation at present is to build at the mouth of the river to block the water dam, and discharging water outside the dam during by retaining in the dam, ebb tide at the incoming tide drives the Hydropower Unit generating, and this method has in encyclopedia more publishes.Though its retaining is can effect better, because reserve-water-level can't improve, the height of water is little, so that its retaining can change into the efficient of electric energy is not high; In addition, the cost of building dam and maintenance is very huge, and will be subjected to the restriction of topography and geomorphology, is difficult to many places and builds, and can't popularize; Moreover it can't be taken into account and utilize wave-activated power generation.

Utilizing at present in the method for wave-activated power generation has preferably: patented technologies such as CN96109685.3 number and CN200410009793.X number, and it exists following deficiency mostly: 1, generator and floating body sealed junction lump together, and that preparation process requires is high, cost is big; 2, allow the labyrinth of comparison precision place on the difficult sea of surveying of stormy waves, be difficult to guarantee its weatherability, and installation, difficult in maintenance; 3, be difficult to the device square formation of generating electricity on a large scale, be difficult to realize powerful generated energy.

Summary of the invention

For overcoming above deficiency, the utility model proposes a kind of high-power non-maintaining morning and evening tides and Wave-activated power generation equipment, it is simple in structure durable, and is non-maintaining, and can realize high-power generating easily with the increase of floating body accumulative total volume, and cost is very low.

Its technological scheme is:

A kind of high-power non-maintaining morning and evening tides and Wave-activated power generation equipment, it includes floating body, anchoring pile, at least two assemblies such as belt pulley, generator and balance weight body, described belt pulley is connected with the driving shaft of generator, floating body is connected between anchoring pile and the belt pulley by cable, other has the rope of walking around pulley, and the rope that is positioned at described pulley one side links to each other with another belt pulley, has balance weight body to be suspended on and is positioned on the rope of described pulley opposite side.

Can directly fix assembling between the driving shaft of described belt pulley and generator is connected.

Can be connected by gear between the driving shaft of described belt pulley and generator.

Described cable can be through at one group of spacing pulley between floating body and the belt pulley that links to each other with floating body.

Described cable can be wrapped on the continuous belt pulley in advance and winding direction and another belt pulley on the winding direction of the rope that twines opposite.

During use, anchoring pile is fixed on the bottom, and belt pulley, generator and balance weight body are arranged on the bank, and floating body floats on the water surface; Along with the rising of the water surface, the cable that is in tensioning state can be subjected to floating body upwards traction and then related belt pulley and generator rotary electrification; When the water surface descended, balance weight body can fall, related another belt pulley and generator counterrotating generating.It is simple in structure durable, and is non-maintaining, and can realize powerful generating easily with the increase of floating body accumulative total volume.

Embodiment

The utility model is described in further detail below in conjunction with embodiment, accompanying drawing.

In Fig. 1, Fig. 2, the utility model first embodiment shown in Figure 3, high-power non-maintaining morning and evening tides and Wave-activated power generation equipment include floating body 2, anchoring pile 1, at least two

belt pulleys

5,7 and assemblies such as generator 4 and balance weight body 10; Described

belt pulley

5,7 is connected with the directly fixing assembling of the driving shaft 6 of generator; Floating body 2 is connected between anchoring pile 1 and the belt pulley 5 by cable 3, and in the present embodiment, the number of floating body is a plurality of; Cable 3 is through one group of spacing pulley 11 between floating body 2 and belt pulley 5; Other has the rope 8 of walking around pulley 9, and the rope that is positioned at pulley 9 one sides links to each other with belt pulley 7, has balance weight body 10 to be suspended on the rope that is positioned at pulley 9 opposite sides; In the present embodiment, cable 3 is by being wrapped in clockwise on the belt pulley 5, and rope 8 is wrapped on the belt pulley 7 counterclockwise.The using process of its equipment is such: during use, anchoring pile 1 is fixed on the bottom, and

belt pulley

5,7 and generator 4 and balance weight body 10 are arranged on the bank, and spacing pulley 11 is fixed near below the water surface on bank, floating body 2 is floated on the water surface, make cable 3 be in tensioning state; Along with the water surface rises, the cable 3 that is in tensioning state can be subjected to upwards traction of floating body 2, during moment that the moment that produces with respect to the driving shaft 6 of generator when the tractive force on the cable 3 produces with respect to the driving shaft 6 of generator greater than the tractive force on the rope 8, driving shaft 6 rotations of cable 3 related belt pulleys 5 of meeting and generator, generator for electricity generation, simultaneously, belt pulley 7 can be with belt pulley 5 rotations, also related rope 8 winding automatically on belt pulley 7, and then, stored the gravitational potential energy of balance weight body through pulley 9 related balance weight body 10 risings; Along with the water surface descends, during moment that the moment that produces with respect to the driving shaft 6 of generator when the tractive force on the cable 3 produces with respect to the driving shaft 6 of generator less than the tractive force on the rope 8, driving shaft 6 counterrotatings of balance weight body 10 meeting whereabouts, related belt pulley 7 and generator, generator also can generate electricity, simultaneously, belt pulley 5 can be with belt pulley 7 rotations, also related cable 3 winding automatically on belt pulley 5; And the continuous variation of water level can cause above-mentioned process to move in circles, and therefore, this equipment can be applicable in morning and evening tides and the generating of wave waters; And because of the structure of the assembly in its water of being everlasting is all very simple, the several years is difficult to damage, so can reach non-maintaining purpose; Can also install large-scale generating square formation, to realize powerful generating.

The utility model second embodiment only is with first embodiment's difference: can be connected by gear between the driving shaft of belt pulley and generator, illustrate this difference among Fig. 4; Among Fig. 4,

belt pulley

5,7 is fixedly connected on earlier on the driving shaft 13 of gear, is connected with the driving shaft 6 of generator through gear 12 again.The difference of its using process is: when belt pulley 5 or belt pulley 7 are subjected to corresponding cable 3, rope 8 related rotations, can drive driving shaft 13 rotations of gear, can make the driving shaft 6 of generator obtain bigger rotating speed through gear 12 simultaneously, to improve the efficient of generating.
