Description

{VEHICLE FOR SPRINKLING WATER}

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a surface water sprayer, and more particularly, to a surface water sprayer provided with an air knife configured to remove wetness of the surface.

Each local government or agency that manages roads conducts regular roadside management on roads already built and used.

For such road surface management, various vehicles such as street sweepers, watering cars are used. Among them, sprinklers can spray water on the road surface to prevent scattering of dust and reduce the heat island effect of roads.

Generally, the water sprayer is provided with a tank portion, and the water supplied from the tank portion can be sprayed to the road surface through the water spraying device.

However, the water spray sprayed on the road surface in the spraying process of the conventional water remover remains on the road surface, which can cause a traffic accident. That is, the sprinkler cleans the road surface by spraying a large amount of water, but the water surface becomes wet due to the water sprayed, which can cause a traffic accident caused by slipping of the vehicle.

In addition, since the conventional watercourse is cleaned on the road surface by spraying a large amount of water, there is a problem in that the working distance due to economic loss and frequent water replenishment is short.

Therefore, it is necessary to study various aspects of road surface sprinkler that can prevent traffic accidents caused by road surface spraying and effectively clean road surface even with a small amount of water.

And liquid is stored in the tank unit 200 installed in the vehicle 100. [ The tank unit 200 supplies the liquid to each water spraying unit 300 installed in the vehicle 100 while the vehicle 100 is operating. Here, the water spraying unit 300 includes a front water spraying unit 310 provided in front of the vehicle 100, a rear spray watering unit 320 provided at the rear of the vehicle, a side spray water spraying unit (not shown) ) May be provided. At this time, the water spray unit 300 is not limited to the water spray unit mentioned above.

The liquid supplied from the tank unit 200 is sprayed to the road surface through the water spraying unit 300 to prevent the scattering dust from being blown and the heat island effect of the road is lowered.

At this time, the tank part 200 can selectively receive various liquids such as water, disinfectant, snow remover, and the like depending on the application.

An auxiliary engine room 110 is installed in the road surface sprinkler 1000 and an auxiliary engine (not shown) is installed in the auxiliary engine room 110. The auxiliary engine provides auxiliary power for use other than the power related to the driving of the vehicle 100 and is provided with a pump unit for supplying liquid (water, snow remover, etc.) to each spraying unit 300 Not shown).

On the other hand, the main air knife 400 is provided at a rear portion of the rear water spraying portion 320.

The main air knife 400 is provided at a rear portion of the vehicle 100. The main air knife 400 blows air at a predetermined pressure to the road surface to remove the liquid sprayed from the water spraying portion 300 onto the road surface, .

The main air knife 400 is made to correspond to the width of the vehicle 100, but is arranged to be inclined with respect to the width of the vehicle 100.

2, the main air knife 400 is not arranged in the same direction as the width direction of the vehicle 100, but is arranged to be inclined with respect to the width direction of the vehicle 100. [ Therefore, the main air knife 400 allows liquid present on the road surface to be guided to the road surface boundary stones 10 when the vehicle 100 is moved forward.

It is needless to say that the angle at which the main air knife 400 is inclined with respect to the width direction of the vehicle 100 can be selectively adjusted by the operator.

On the other hand, the side air knife 500 is made rotatable from the vehicle 100.

This side air knife 500 can be selectively rotated according to the spraying operation. The side air knife 500 may be installed on the road surface boundary stone 10 so that the side air knife 500 is placed on the road surface barrier 10, As shown in Fig. In this case, the side air knife 500 is made to remove the liquid sprayed from the side spray portion.

The side air knife 500 is rotated in the vertical direction so as not to protrude to the side of the vehicle 100 when the road surface sprayer 1000 only runs spraying work on the road surface or only runs the vehicle without spraying. Thus, the side air knife 500 can be prevented from colliding with the external obstacle.

The side air knife 500 has a length different from that of the main air knife 400, and the structure corresponds to that of the main air knife 400. Therefore, in the present invention, the side air knife 500 and the main air knife 400 among the main air knife 400 will be described as an example.

FIG. 5 is a perspective view of the main air knife according to the embodiment of the present invention, and FIG. 6 is a cross-sectional view of the main air knife according to an embodiment of the present invention. FIG. 7 is a cross-sectional view of the main air knife according to an embodiment of the present invention, FIG. 8 is a cross-sectional view taken along the line I-I of FIG. 4, Fig. 6 is an operational state diagram showing an air movement flow of a main air knife according to an embodiment of the present invention.

4 to 9, the main air knife 400 includes an air supply unit 410, a first air chamber 420, a second air chamber 430, a partition wall unit 440, 450, a discharge flow rate regulator 460, and a blocking block 470.

The air supply unit 410 is configured to form an air discharge pressure of the main air knife 400 injected onto the road surface.

The air supply unit 410 may include a wind power generation unit 411 and a filter unit 412.

This wind power generating unit 411 may be a blower and provides a ground output of air injected from the main air knife 400 to the road surface.

The air blowing force generating unit 411 is configured to supply outside air to the first air chamber 420 after the outside air is introduced. At this time, the wind power generation unit 411 supplies the filtered air through the filter unit 412 to the first air chamber 420. That is, the air supplied from the air supply unit 410 to the first air chamber 420 may be filtered air such as foreign matter and fine dust.

Meanwhile, the first air chamber 420 is connected to the air supply unit 410. The first air chamber 420 is configured to uniformly supply the air supplied from the air supply unit 410 to the second air chamber 430 as a whole.

The first air chamber 420 has a circular pipe shape and corresponds to the length of the main air knife 400.

A plurality of air ejection holes 421 are formed in the upper portion of the first air chamber 420 at predetermined intervals along the longitudinal direction of the first air chamber 420. That is, the air supplied from the air supply unit 410 may be supplied to the second air chamber 430 through the air ejection holes 421 formed along the longitudinal direction of the first air chamber 420. Therefore, a uniform air supply can be provided to the inside of the second air chamber 430.

Here, since the air ejection hole 421 is formed only on the upper portion of the first air chamber 420, the same air pressure can be maintained over the entire length of the first air chamber 420. Therefore, the jetting intensity of the air ejected from each of the air ejection holes 421 formed along the longitudinal direction of the first air chamber 420 may be the same. That is, since air supplied from the first air chamber 420 to the second air chamber 430 is supplied only through the air spray holes 421, the entire interior of the first air chamber 420 is maintained at a predetermined pressure Lt; / RTI > In other words, the same air pressure can be maintained for the entire lengthwise direction of the first air chamber 420.

Even if the main air knife 400 is long, the jetting intensity of the air injected from the main air knife 400 to the road surface may be the same for the longitudinal direction of the main air knife 400. Therefore, the road surface sprinkler 1000 can effectively perform road surface cleaning with only one main air knife 400.

Meanwhile, the second air chamber 430 is configured to receive air supplied from the first air chamber 420. The second air chamber 430 has a receiving space portion 431 formed therein and the first air chamber 420 can be received in the receiving space portion 431.

Here, the second air chamber 430 is formed of a polygon whose cross section is not completely closed. That is, one end and the other end of the second air chamber 430 having a polygonal cross section are not connected to each other. The first and second ends of the second air chamber 430, which are not connected to each other, are spaced apart from each other to form a jetting guide hole 432 through which the air is discharged from the second air chamber 430 to the outside.

Here, a jetting guide hole 432 formed in a slit shape formed in the longitudinal direction of the second air chamber 430 is formed at a lower portion of the second air chamber 430. Accordingly, the air introduced into the second air chamber 430 through the first air chamber 420 can be injected into the road surface through the injection guide hole 432.

In the present invention, the second air chamber 430 has a hexagonal shape. However, the second air chamber 430 is not limited to the hexagonal shape. Since the second air chamber 430 is formed in a polygonal shape, the injection direction guide portion 450 and the discharge flow rate control portion 460, which are coupled to the outer surface of the second air chamber 430, 430, respectively. The second air chamber 430 corresponds to the length of the main air knife 400 as the first air chamber 420.

Meanwhile, the partition wall portion 440 is provided in the receiving space portion 431 and below the first air chamber 420. The air in the second air chamber 430 is discharged to the outside through the jetting guide hole 432 so that the air is uniformly discharged in the longitudinal direction of the second air chamber 430 Respectively.

The partition wall 440 may include a support bar 441 and a partition plate 442.

Here, the support bar 441 is configured to support the plurality of partition plates 442.

The supporting bar 441 has a length corresponding to that of the second air chamber 430 and both ends of the supporting bar 441 are fixed to the second air chamber 430.

The barrier ribs 442 are spaced apart from each other at predetermined intervals along the longitudinal direction of the support bars 441. At this time, the partition plate 442 is coupled to the inner surface of one end and the other end of the second air chamber 430. Accordingly, the air discharged through the jetting guide hole 432 can be uniformly discharged.

Thus, the main air knife 400 can be uniformly injected in the longitudinal direction of the main air knife 400. That is, the first air chamber 420 is configured to supply generally uniform air to the second air chamber 430 in the longitudinal direction of the first air chamber 420, and the partition plate 442 is configured to supply air, So that uniformly uniform air is discharged to the outside with respect to the longitudinal direction of the discharge port 430.

Therefore, the air injected to the road surface through the main air knife 400 can be uniformly injected uniformly in the longitudinal direction of the main air knife 400.

As such, the main air knife 400 has a dual chamber structure of the first air chamber 420 and the second air chamber 430, so that the air pressure in the chamber can be maintained at a predetermined pressure or more.

Therefore, even if the main air knife 400 is formed long, the air injected to the road surface through the injection guide hole 432 can be uniformly sprayed while maintaining the required air pressure.

On the other hand, the injection direction guide portion 450 is coupled to the outer surface of one end of the second air chamber 430. The jetting direction guide portion 450 guides the jetting direction of the air discharged from the jetting guide hole 432.

Here, the jetting direction guide unit 450 is coupled to the second air chamber 430 so that the air discharged from the jetting guide hole 432 is forwardly directed and downward jetted.

The discharge flow rate regulator 460 is coupled to the outer surface of the other end of the second air chamber 430. The discharge flow rate regulator 460 adjusts the discharge amount of the air injected to the road surface through the gap with the spray direction guide part 450.

The discharge flow rate regulator 460 is provided with an elongated hole h so that the interval between the elongated hole h and the jet direction guiding portion 450 can be selectively controlled. That is, the operator can adjust the discharge amount of the air sprayed on the road surface by selectively adjusting the position of the discharge flow rate regulator 460 according to the road surface, the work state, and the like.

The jetting direction guide unit 450 and the discharge flow rate regulating unit 460 have a length corresponding to that of the second air chamber 430.

Meanwhile, the blocking block 470 is provided on the entirety of the second air chamber 430.

The blocking stopper 470 is configured to minimize the influence of the outside air from the main air knife 400 to the road surface. For example, when the operation of the main air knife 400 is performed while the road surface sprinkler 1000 is running, the blocking stopper portion 470 may prevent the influence of the wind generated by the running of the road surface sprayer 1000 to a minimum So as to reach the main air knife 400. The blocking member 470 also protects the main air knife 400 from the outside.

The blocking stopper 470 may include a connection frame 471 and a blocking wall 472.

The connection frame 471 is coupled to the second air chamber 430 and is configured to support the blocking wall 472.

The blocking wall 472 is provided on the entirety of the second air chamber 430 and is spaced apart from the second air chamber 430 by a predetermined distance.

Here, it is preferable that the lower end of the blocking wall 472 is positioned below the jetting direction guide portion 450. This is so that the air injected to the road surface under the guidance of the spray direction guide unit 450 is minimally influenced by the outside.

Therefore, even when the road surface sprayer 1000 is running, the main air knife 400 receives the influence of outside air to the minimum, and can effectively spray air toward the road surface.

It should be understood, however, that the scope of the present invention is not limited by the scope of the present invention.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be.
