Description

[0001] EFFICIENCY ENHANCEMENT EQUIPMENT FOR SOLAR PHOTOVOLTAIC POWER FACILITIES [0002]

The present invention relates to a facility for improving efficiency of a photovoltaic power generation facility, and more particularly, it can be applied to a photovoltaic module installed at a small scale, such as a home, to ensure economic feasibility, and to variously set a method of using cooling water for cooling and cleaning. The present invention relates to a facility for improving efficiency of photovoltaic power generation facilities.

Generally, the method of using solar energy is divided into a method using solar heat and a method using sunlight. The method of using solar heat is a method of heating and generating electricity by using water heated by the sun, and a method of using sunlight is a method of generating electricity by using sunlight, It is called solar power generation.

Among the above-mentioned methods, photovoltaic power generation is a photovoltaic effect in which a photovoltaic panel having n-type doping on a silicon crystal and pn-junction is irradiated with sunlight to generate an electromotive force due to the photovoltaic energy, To generate electricity.

For this purpose, a solar cell for collecting sunlight, a photovoltaic module as an aggregate of solar cells, and a solar array for uniformly arranging solar cells are required.

For example, when light is incident on the solar module from the outside, electrons in the conduction band of the p-type semiconductor are excited to the valence band by the incident light energy. One electron-hole pair (EHP) is formed inside the p-type semiconductor, and electrons in the electron-hole pair generated are transferred to the n-type semiconductor by an electric field existing between the pn junctions. It passes over and supplies current to the outside.

Unlike existing energy sources such as fossil raw materials, sunlight is a clean energy source that does not have the danger of global warming, such as greenhouse gas emissions, noise, environmental destruction, etc., and there is no fear of depletion. Unlike other types of wind and seawater, solar power generation facilities are free from installation and maintenance costs.

However, in the case of the most widely used silicon solar cell, when the temperature of the photovoltaic module is increased, a power reduction of 0.5% per 1 ° C occurs. According to these characteristics, the output of photovoltaic power is highest in spring and autumn, not the longest summer. Such a temperature rise is a major cause of deteriorating the power generation efficiency of the photovoltaic power generation.

In addition, such a solar module has disadvantages that dust can be easily accumulated on the solar panel due to weather phenomenon such as yellow dust and bad weather. When dirt accumulates on the solar module, the solar module's light absorption rate is significantly lowered, and therefore the power generation efficiency may also be lowered.

In addition, when rain or snow falls on the solar panel in winter, the power generation efficiency may decrease.

In order to prevent such deterioration of power generation efficiency due to dirt, snow, and rain, the efficiency improvement equipment (maintenance equipment) of photovoltaic power generation facilities is used.

In order to improve the efficiency of solar power generation facilities, the cooling module which cools the temperature of the solar module and the cleaning and snow removal of the dirt, snow, rain etc. accumulated on the solar panel, It functions to maintain the solar power generation facilities.

And rotatably coupled to each other and disposed adjacent to one side of the separating diaphragm 200 to rotate by the flow force of the coolant passing through the first and second flow holes 210 and 220 of the separating diaphragm 200. It is configured to. The flow direction of the coolant passing through the first and second flow holes 210 and 220 has components opposite to each other as described above, wherein the first and second flow holes 210 and 220 are rotated open / close unit 400 to be described later. The rotation aberration 300 is reciprocally rotated in both directions by the flow force of the coolant having the components in the opposite direction passed through the first flow hole 210 or the second flow hole 220 so as to be alternately opened and closed by.

The rotation opening / closing unit 400 is rotatably mounted inside the rotating body 100 so as to reciprocately rotate in conjunction with the reciprocating rotation of the rotation aberration 300, and alternates the first and second flow holes 210 and 220 according to the rotation. It is configured to open and close with. The rotation opening and closing unit 400 is interlocked with the rotary aberration 300 by a separate link unit 500, the link unit 500 is a variety of ways through a variety of power transmission mechanical elements, such as a plurality of link plates, chains, belts 12 and 13, it may be configured using a plurality of gears.

The injector 60 to be described later is configured to communicate with the internal space of the rotor 100 through the outlet 111 to inject the coolant discharged from the rotor 100. In addition, the injection body 60 is coupled to the rotation opening and closing unit 400 inside the rotating body 100 rotates integrally with the rotation opening and closing unit 400 and injects coolant. Therefore, since the injector 60 rotates and injects the coolant, the coolant is evenly sprayed on the entire area of the solar module 10.

According to this structure, the rotating body 100 is supplied with cooling water, and the rotary aberration 300 reciprocally rotates by the flow force of the cooling water alternately passing through the first and second flow holes 210 and 220 so that the upper injection body 60 is rotated. Rotate).

Therefore, the rotating body 100 is configured to rotate the upper injector 60 through a mechanical mechanism without using an additional electric power, which is excellent in energy efficiency and smoothly performs the washing function of the solar module 10. It has a structure that can be done.

Next, the mechanism for rotating the injector 60 in both directions according to an embodiment of the present invention will be described in more detail.

As described above, the separating diaphragm 200 is fixed to the inside of the rotating body 100 in a flat shape as described above, and the separating diaphragm 200 has first and second flow holes 210 and 220 formed therein. At least one first and second flow holes 210 and 220 are each formed to have a straight flow path formed to be inclined with respect to the thickness direction of the separating plate 200.

In this case, the inclination directions of the first and second flow holes 210 and 220 may be symmetrically formed with respect to the thickness direction of the separation plate 200. For example, the first flow hole 210 is formed to be inclined to form a coolant flow force that rotates the rotation aberration 300 counterclockwise with reference to FIG. 15, and the second flow hole 220 is formed as the rotation aberration ( It may be inclined to form a coolant flow force for rotating the clockwise 300.

Accordingly, the coolant passing through the first flow hole 210 has a flow direction component formed along the inclined direction of the first flow hole 210 to rotate the rotation aberration 300 counterclockwise, and the second flow hole ( The coolant passing through 220 forms a flow direction component along the inclination direction of the first flow hole 210 and the second flow hole 220 which are symmetrical with each other, thereby rotating the rotation aberration 300 clockwise.

At this time, the first and second flow holes (210, 220) are each in the circumferential direction to the separation diaphragm 200, as shown in Figure 15 to 17 for reinforcement of the coolant flow force for rotating the rotary aberration (300) Each of the first and second flow holes 210 and 220 may be formed in alternating positions along the circumferential direction. Dogs and so on will be variously modifiable.

On the other hand, the rotation opening and closing unit 400 is reciprocating in both directions in conjunction with the reciprocating rotation of the rotary aberration 300 and alternately open and close the first and second flow holes (210, 220). Accordingly, the first and second flow holes 210 and 220 are alternately opened and closed by the reciprocating rotation of the rotary opening and closing unit 400, and the coolant flows through the first and second flow holes 210 and 220 alternately. The power has components opposite to each other, so that the rotation aberration 300 reciprocates, and the reciprocation of the rotation aberration 300 again generates a circulation mechanism for reciprocating the rotation opening and closing unit 400. By this circulation mechanism, the reciprocating rotation of the rotary aberration 300 and the rotary opening / closing unit 400 is continuously repeated as long as cooling water is supplied into the rotating body 100.

Looking at the configuration of the rotation opening and closing unit 400 in more detail, the rotation opening and closing unit 400 is directly connected and coupled to the link unit 500 according to an embodiment of the present invention to rotate in conjunction with the rotation aberration 300 The rotary block unit 410 and the rotary block unit 410 are engaged with the rotary block unit 410 to rotate integrally with the rotary block unit 410 and to the separation plate 200 to open and close the first and second flow holes 210 and 220 alternately. It is configured to include an opening and closing clutch portion 430 is contacted.

At this time, the rotary block 410 is connected to the link unit 500 in accordance with an embodiment of the present invention so as to communicate with the circular rotary plate 411, the through-hole 416 formed in the center portion, the through-hole 416 A connecting sleeve 412 protruding from one surface of the rotating plate 411 to be coupled to the spraying body 60, and the longitudinal direction of the rotating body 100 on the outer side of the rotating plate 411 to be engaged with the opening and closing clutch unit 430. It may be configured to include a hook bar 413 extending along the, the rotating plate 411, the connecting sleeve 412 and the hook bar 413 is preferably formed integrally, each formed separately and are mutually coupled It may also be produced in a manner.

At this time, the connection sleeve 412 is configured to be detachably coupled to the injection body 60, such a detachable coupling method can be applied by a fitting coupling method or a screw coupling method using a fastening tip described later, in addition to It can be changed in various ways such as bolt fastening method.

In addition, the opening and closing clutch unit 430 is in contact with one side of the separating diaphragm 200 in accordance with an embodiment of the present invention so as to rotate integrally with the operating plate 431, the operating plate 431 It is coupled to engage the engaging bar 413 of the rotary block 410, and includes an operation locking plate 432 formed to protrude to the outside of the separation plate 200 to rotate, the operating plate 431 is rotated The first and second flow holes 210 and 220 may be configured to be opened and closed alternately, and the operating plate 431 and the operating stopping plate 432 may be integrally formed with each other. Meanwhile, the opening and closing clutch unit 430 may further include an elastic spring 433 for elastically biasing the operating plate 431 such that the operating plate 431 rotates in the direction of closing the first flow hole 210. have.

Therefore, the rotation opening / closing unit 400 is formed of the rotation block part 410 and the opening / closing clutch part 430 to be coupled to the injection body 60 to perform the function of rotating the injection body 60 and the first and the same. A function of alternately opening and closing the second flow holes (210, 220).

When the operation state of the rotation opening and closing unit 400 is divided into the rotation block unit 410 and the opening / closing clutch unit 430 to examine in more detail, first, the rotation block unit 410 is rotated by the link unit 500 ( Rotate in conjunction with 300).

More specifically, as shown in FIG. 14, when the rotary aberration 300 reciprocates, the circular rotary plate 411 and the connecting sleeve 412 which are directly coupled to the link unit 500 reciprocately rotate. The injection unit 60 coupled to the connecting sleeve 412 is reciprocated.

In addition, when the connecting sleeve 412 reciprocally rotates, the catching bar 413 extending to the outer side of the connecting sleeve 412 is also reciprocally rotated, in which case the catching bar 413 actuates the engaging plate of the opening / closing clutch unit 430. Since the engaging plate 432 is engaged with the operation locking plate 432 is to reciprocate rotation with the locking bar (413).

When the operation stopping plate 432 reciprocally rotates, the operation plate 431 integrally coupled thereto rotates reciprocally, and the first and second flow holes 210 and 220 alternately according to the reciprocating rotation of the operation plate 431. It is opened and closed. Selective opening and closing of the first and second flow holes 210 and 220 induces reciprocation of the rotation aberration 300 again as described above, and as a result, the rotation opening and closing unit 400 continuously reciprocates.

At this time, the locking bar 413 of the rotary block portion 410 and the operation locking plate 432 of the opening and closing clutch unit 430 may be formed to be engaged when both of the locking bar 413 rotates in both directions, as shown in FIG. As described above, the engagement bar 413 may be configured to be engaged only in one direction rotation and to be disengaged in the opposite direction. For example, as shown in (a) of FIG. 17, in the state in which the operating plate 431 and the operating stopping plate 432 are rotated with the first flow hole 210 closed, the locking bar 413 When the rotation in one direction is engaged with the operation locking plate 432 is rotated to rotate the operating plate 431 to close the second flow hole 220 as shown in (b) of FIG.

When the locking bar 413 rotates in the opposite direction while the operation plate 431 closes the second flow hole 220, in this case, the operation locking plate 432 is connected to the locking bar 413. Since the engagement plate 432 and the operation plate 431 do not rotate, the second flow hole 220 is kept closed because it is not engaged.

Therefore, in this case, as shown in FIG. 17, the operating plate 431 is rotated to close the first flow hole 210 by a separate elastic spring 433 for elastically biasing the operating plate 431.

On the other hand, the rotation opening and closing unit 400 is to be reciprocated in accordance with the operation principle described above, such a rotation opening and closing unit 400 is a separate rotation stopper so that the reciprocating rotation angle can be adjusted according to an embodiment of the present invention ( 420 may be mounted. That is, as shown in FIG. 14, the rotary stopper 420 protruding outward of the rotary block 410 is coupled to the upper surface of the rotary plate 411 of the rotary block 410, and the On one side of the inner circumferential surface, a fixing protrusion 132 that may be engaged with the rotary stopper 420 may be formed as the rotary stopper 420 rotates.

Therefore, the maximum rotation angle of the rotation block 410 is limited by the rotation stopper 420 and the fixing protrusion 132. At this time, the rotary stopper 420 may be coupled to the connection sleeve 412 through the coupling hole 421 to be penetrated, the coupling protrusion 422 is formed on the inner peripheral surface of the coupling hole 421 And the outer circumferential surface of the connecting sleeve 412 is formed with a plurality of coupling grooves 415 which can be inserted into the coupling protrusion 422 spaced along the circumferential direction, by the coupling protrusion 422 and the coupling groove 415 The rotary stopper 420 may be detachably coupled to the rotary block 410.

Therefore, the coupling position of the rotary stopper 420 is changed to have various relative positions with respect to the rotating plate 411 according to the position of the coupling groove 415 to which the coupling protrusion 422 is coupled among the plurality of coupling grooves 415, According to the change of the coupling position, the maximum rotation angle of the rotation block part 410 limited by the rotation stopper 420 is adjusted.

Next, looking at the link unit 500 for interlocking the rotary opening and closing unit 400 and the rotary aberration 300 in more detail, the hollow cylinder in which the teeth (G) of the gear is formed on the inner peripheral surface of the rotary opening and closing unit 400 Gear teeth 414 are formed, the link unit 500 may be configured to include a plurality of gears that are engaged to the rotation opening and closing unit 400.

Here, the conveying port is for guiding the cooling water flowing from the connecting sleeve 412 of the rotation opening / closing unit 400 to the outlet, which is connected to the fastening pipe 614, the communication pipe 618, and the discharge pipe 616 integrally connected to each other. Hollow means, the inlet of the conveyance means the hollow of the fastening pipe 614 and the outlet of the conveyance means the hollow of the discharge pipe 616.

In addition, the fastening tube 614 extends downward to be fastened with the connection sleeve 412 of the rotation opening / closing unit 400 and protrudes to the outside of the coupling space 610 to form a protrusion 628 having a stepped fastening tip ( A plurality of 630 is formed at the end. In this case, the fastening tip 630 may be compressed to the inside of the connection sleeve 412 of the rotation opening / closing unit 400 or may be fastened to a step or groove.

The embodiment according to the present invention illustrates that the fastening tip 630 is configured at the end of the fastening pipe 614, but is not limited thereto, and may be variously implemented according to the intention of the manufacturer. When the female thread is configured in the connecting sleeve 412, the end of the fastening tube 614 may be configured by processing with a male screw.

In addition, the inner diameter of the discharge pipe 616 forming the outlet of the transfer unit is preferably configured to be larger than the inner diameter of the communication pipe 618, so that a step is formed at the boundary between the discharge pipe 616 and the communication pipe 618.

In addition, an outer wall 620 and an inner wall 622 which are separated and extended downward from the bottom surface 613 are formed on the case 612 of the nozzle cap 600, and the outer wall 620 has an outer edge of the case 612. The inner wall 622 forms a reinforcing structure between the outer wall 620 and the fastening tube 114 under the case 612 to form a coupling space 610.

In addition, the upper surface of the discharge pipe 616 forming the outlet of the nozzle cap 600 is formed with a screw portion 626 having a threaded hole 624 penetrating the side wall, the screw hole 624 is screwed to the screw 608 . In this case, the screw 608 supports a fixed state of the air chamber 604 located in the discharge pipe 616.

On the other hand, the orifice 602 is inserted into the conveying hole of the nozzle cap 600, that is, in the communication tube 618 and sprays the coolant flowing through the fastening tube 614 forming the conveying port toward the discharge pipe 616 forming the outlet of the conveying port. Has the function to

For this purpose, the orifice 602 has an annular rim 634 having a diameter larger than the outer diameter of the orifice tube 632 at one end of the orifice tube 632 and the orifice tube 632 in which the hollow is formed and communicates with the orifice tube 632. While having an orifice sphere 636 having a small diameter has a configuration including a discharge portion 638.

The orifice 602 is inserted into the communication tube 618 is fixed so that the annular rim 634 is caught on the step formed between the communication tube 618 and the discharge pipe 616.

Here, the difference in diameter between the hollow of the orifice tube 632 and the orifice sphere 636 is large. Therefore, the cooling water pressurized into the orifice tube 632 is passed through the orifice sphere 636 by the 'Bernoulli' theorem, and the speed increases and the internal pressure decreases.

That is, the orifice 602 directs the coolant to its connected air chamber 604 at high speed and low pressure. Accordingly, the pressure inside the air chamber 604 is lowered.

The orifice 602 may vary in flow rate depending on the size of the orifice sphere 636.

On the other hand, the configuration of the air chamber 604 coupled to the orifice 602 will be described.

The air chamber 604 is partially inserted into the discharge pipe 616, which is the outlet of the transfer port of the nozzle cap 600, and the inserted end thereof is coupled with the orifice 602 and spaced between the inner wall of the discharge pipe 616 of the nozzle cap 600. Has Accordingly, the air chamber 604 is guided along the clearance formed between the coolant injected from the orifice 602 and the discharge pipe 616 of the nozzle cap 600 and its side 644 and the ideal flow of air introduced into the interior of the air chamber 604. It has the function to occur.

The configuration of the air chamber 604 having the above function will be described in more detail.

The air chamber 604 includes a coupling portion 640 coupled to the outlet portion 638 of the orifice 602, a connection portion 642 inserted into an inlet of the injection tip 606, and a coupling portion 640 and the connection portion 642.

And, the air chamber 604 is a plurality of through holes 650 to ensure that air is introduced into the side wall 644 between the coupling portion 640 and the annular rib 648 closest to the coupling portion 640. Is formed and a part of the side wall 644 is inserted into the discharge pipe 116 of the nozzle cap 100.

As described above, since the air chamber 604 is configured, the clearance between the discharge pipe 616 and the side wall 644 is reduced by the coolant injected at a high speed and low pressure from the orifice 602 and the low pressure therein. An abnormal flow of air introduced through the open region 646 and the through hole 650 of the annular rib 648 occurs.

That is, a fluid mixed with air and coolant by the abnormal flow generated in the air chamber 604 is provided to the injection tip 606, where the fluid has a pulse by the abnormal flow and the frequency of the pulse is the through hole 650. It can be adjusted by the variable number of the air inflow is adjustable by varying the size of the through-hole 650. The pulse of the fluid due to the abnormal flow is increased by reducing the number of through holes 650 and is lowered by increasing the number of through holes. In addition, the amount of inflow of air increases when the size of the through hole 650 increases, and decreases when the size of the through hole 650 is reduced.

Meanwhile, as described above, the fluid in which the coolant and the air are mixed by the abnormal flow generated in the air chamber 604 proceeds to the injection tip 606 and may be injected into the collision jet through the injection tip 606.

Here, the injection tip 606 may be detachably coupled to the end exposed to the outside of the discharge pipe 616 of the nozzle cap 600 of the air chamber 604, the injection tip 606 and the discharge pipe 616 It is coupled to maintain the separation interval and the combination of the injection tip 606 as described above ensures that the air can be introduced into the spaced space between the air chamber 604 and the discharge pipe 616.

The injection tip 606 has a shape in which the injection inlet 652 and the injection outlet 654 communicate with each other and narrow toward the injection outlet 654 at a predetermined inclination angle. The angle of inclination narrowing toward the injection outlet 654 may determine the angle of injection of the fluid. The connecting portion 642 of the air chamber 604, which is coupled with the injection inlet 652 of the injection tip 606, may be formed of a plurality of protrusions sufficient to obtain a supporting force for engagement with the inner wall of the injection inlet 652. Can be.

The injection angle corresponds to the extent to which the impingement jet is injected at the injection outlet 654 of the injection tip 606. The abnormal flow generating nozzle according to the present invention may change the injection angle of the fluid jet by changing the injection tip 606 that is detachably configured to vary the injection angle of the collision jet according to the object to be cooled and cleaned.

Accordingly, the fluid with pulses propagating from the air chamber 604 enters the injection tip 606 through the injection inlet 652 and is injected through the injection outlet 654 with a collision jet having a particular injection angle.

18 to 22, the injector 60 according to the present invention may be implemented. Referring to FIG. 23, an ideal flow of coolant and air in the injector 60 and impingement jet injection of the fluid will be described. do.

Cooling water pressurized and supplied from the connecting sleeve 412 of the rotation opening / closing unit 400 flows in as shown by arrow A1 through the fastening pipe 614 of the nozzle cap 600, and the coolant is connected to the fastening pipe 614. After moving to 618, it flows into the orifice tube 632 of the orifice 602 as shown by arrow A2, and then passes through the orifice port 636 as shown in Table A3 and is discharged into the air chamber 604 at high speed and low pressure. .

As described above, as the coolant is discharged into the air chamber 604 through the orifice 602, a low pressure is formed in the air chamber 604. Accordingly, air flows along the side wall of the air chamber 604 as shown by arrow A4 and air flows inside as shown by arrow A5 through the through hole 650 formed in the side wall 644 of the air chamber 604.

As a result, an abnormal flow of the coolant and the air is generated in the air chamber 604. As a result, the fluid having a pulse is injected through the injection tip 606 as the arrow A6 into the impinging jet as the coolant and the air are mixed.

As described above, in the present invention, since an abnormal flow occurs in the nozzle, a component to which a fluid caused by the abnormal flow is affected can be minimized. That is, it does not affect the parts (aberration, etc.) for supplying the cooling water by pressurizing, that is, the parts of the rotating body 100 formed before the fastening pipe 114 of the nozzle cap 100, so that the life of the parts can be guaranteed. As a result, the reliability of the installation can be secured.

In a general case, the impingement jet may be injected as shown in FIG. 24, but the impingement jet according to the abnormal flow of the present invention has a spraying type by a pulse as shown in FIG. 25.

As illustrated in FIG. 25, the collision jet injected by the embodiment according to the present invention increases the heat transfer coefficient as the pulsation frequency increases during the collision injection. Therefore, the cooling and cleaning effect can be increased.

In addition, according to the present invention, since the air is abnormally flowed together and mixed in the fluid, the amount of cooling water used may be reduced by that amount.

As described above, according to the embodiment of the present invention, the tap water can be used for cleaning and cooling the solar modules 10a and 10b without the need for a coolant tank or a pump, and the user can use both the spray interval and the spray amount. Coolant can be supplied for cleaning of the solar modules 10a and 10b at a predetermined spray interval and spray amount, and the coolant is supplied by the distributor 5 to the solar modules 10a and 10b. Since each of the cooling water injection means (9a, 9b, 9c, 9d) is configured to be sequentially supplied to the cooling water can be supplied in a high pressure state, the cooling water injection means (9a, 9b, 9c, 9d) is impingement jet By spraying on, the solar modules 10a and 10b can be efficiently cooled and cleaned.
