The present invention relates to a soundproof wall cleaning device, and more particularly, it is easy to clean various soundproof walls installed on the roadside or inside a tunnel, and in particular, the washing operation can be easily performed by dry cleaning method using solid washing particles. It relates to a soundproof wall cleaning device.

In general, a soundproof wall structure is installed in a road or a tunnel to reduce various noises such as a mechanical friction sound or a road surface friction sound. Such a soundproof wall structure deteriorates the soundproofing effect by easily attaching various dusts or metal dusts generated while driving a vehicle. Of course, it hurts the aesthetics, so you need to clean the surface periodically.

In this way, the cleaning of the soundproof wall surface is mostly performed by a wet cleaning method in which a worker moves directly along the installation section of the soundproof wall using a hose connected to a tank containing the cleaning liquid and sprays the cleaning solution toward the soundproof wall surface. .

However, the wet cleaning method as described above not only contaminates the appearance of the driving vehicle because contaminated washing liquid is accumulated on the road as the washing liquid sprayed downward toward the soundproof wall during the washing operation not only contaminates the appearance of the driving vehicle, but especially in the winter when the temperature is low As it is frozen on the road surface, it can be a factor causing safety accidents when driving a vehicle.

In addition, since the cleaning operation must be performed while the cleaning equipment is moved along the installation section of the soundproof wall structure during the cleaning operation, the operation is difficult and there is a problem of lowering the traffic flow. Moreover, since the worker performs the washing operation on the road surface, a large safety accident may occur by the driving vehicle.

In addition, the manner in which the worker proceeds the washing operation by hand while moving along the soundproof wall structure as described above takes too much time for the washing operation, it is difficult to continuous work can not expect satisfactory work efficiency.

The present invention is devised to solve the conventional problems as described above, the object of the present invention is to simply proceed with the cleaning operation of the soundproof wall while moving along the vehicle, in particular by using dry washing particles The present invention provides a soundproof wall cleaning apparatus capable of cleaning the soundproof wall surface by a cleaning method.

In order to realize the object of the present invention as described above,

A vehicle body provided with a loading unit,

A storage tank containing a number of solid washing particles and positioned on the loading part;

An injector having a nozzle passage which is connected to receive an infinite number of solid washing particles from the storage tank and has branching protrusions formed to contact each washing particle in a uniformly distributed state;

A gas generator which generates a pressure gas and contains countless solid washing particles contained in the storage tank to be injected into the nozzle passage of the injector.

It provides a soundproof wall cleaning device comprising a.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiments of the present invention are described to the extent that those of ordinary skill in the art can implement the present invention.

Therefore, since the embodiments of the present invention can be modified in many different forms, the utility model registration claims of the present invention are not limited to the embodiments described below.

1 is a view showing the overall structure of the soundproof wall cleaning apparatus according to an embodiment of the present invention, 2 denotes a working vehicle (2).

This working vehicle 2 may be a conventional cargo loading truck provided with a flat loading part 4 at the rear as shown in the drawing.

The storage tank (T) is located on the loading portion (4), and the storage space (S) is provided in the tank (T) to contain countless solid washing particles (W) for dry cleaning operations.

The countless solid washing particles (W) are dry ice (dry ice) particles are used, the particle size of approximately 2mm to 3mm.

Such washing particles (W) can be produced in the form of a cylinder or polygonal cylinder having the above-described particle size, for example, using a conventional dry ice processing apparatus.

The dry ice used as the washing particles (W) is a solid carbonic acid having a high purity of snow shape, frozen in carbon dioxide, as it is well known, in particular, since the heat of vaporization is large compared to the weight and does not get wet unlike ice.乾 式 It is preferred as solid washing particles (W) for washing.

That is, the dry ice washing particles (W) is in a dry manner because various dusts or dusts on the surface adhere to the particles (W) and vaporize in this state when they are in contact with the surface to be cleaned. Cleaning can proceed.

Dry cleaning using such dry ice washing particles (W), for example, compared to the conventional wet cleaning method that proceeds the cleaning operation while spraying the cleaning liquid, it is possible to reduce the contamination of the road surface, especially the temperature It is possible to solve the problem of causing driving obstacles when driving the vehicle by preventing the washing liquid from freezing on the road surface in the low winter.

And, the storage tank (T) is made so that the countless solid washing particles (W) contained in the storage space (S) is discharged to enable the cleaning operation by the gas pressure.

To this end, in this embodiment, as shown in FIG. 2, two ports P1 and P2 communicating with the storage space S are formed and are driven by the pressure gas A flowing in one direction through the ports P1 and P2. Countless solid washing particles (W) are to be discharged.

One of the two ports P1 and P2 is a port P1 from which the pressure gas A is introduced from the outside, and the introduced pressure gas A is discharged through the other port P2 in one direction. Passed into the flow.

That is, the inside of the storage tank (T) has a constant pressure through the two ports (P1, P2) and when the water passes in one-way flow as shown in FIG. It may be made of a passage structure such as a conventional venturi tube that can suck the solid washing particles (W) to be discharged to the discharge side port (P2).

In the above description that the storage tank (T) is limited to the function of storing a myriad of solid washing particles (W) in the description and drawings as an example, but is not limited thereto.

For example, although not shown in the drawing, conventional apparatuses for aggregating atmospheric carbon dioxide in the storage tank T, expanding and cooling the aggregated carbon dioxide, and making dry ice are provided in the storage space S. You can also make your own supply of dry ice.

The storage tank (T) is connected to the gas generator (6) so that the countless solid washing particles (W) contained therein can be injected by the pressure gas (A).

The gas generator 6 may be a conventional compressor for generating pressure air, and is installed on the loading section 4.

The gas generator (6) is the inlet port (P1) and the hose (H) of the tank (T) so that the pressure air generated during operation, that is, the pressure gas (A) can be supplied to the storage tank (T) It is connected to the pressure gas (A) is supplied through this inlet port (P1) is made possible to discharge to the discharge port (P2).

As the negative pressure acts on the inside of the storage space S by the flow pressure of the pressure gas A moving in one direction as described above, countless solid washing particles W are sucked into the pressure gas A, and the pressure gas ( Together with A) is discharged to the discharge side port (P2).

The gas generator 6 is connected to the storage tank (T) and the hose (H), as shown in Figure 2 or in addition to not shown in the figure, but installed integrally to the above operation in the storage tank (T) Can be.

On the other hand, the storage tank (T) is connected to the injector (8) as shown in Figure 2 so that a number of solid washing particles (W) contained therein can be injected.

This injector 8 is provided with a nozzle passage (N) inside as shown in Figure 3, the nozzle passage (N) is countless solid washing particles (W) from the discharge port (P2) of the storage tank (T) ) Is connected to the hose (H) to be supplied.

The hose (H) may be used a conventional corrugated pipe can be flexibly connected to the connecting section. By using the flexible corrugated pipe in this way, the position of the injector 8 can be easily changed.

And, the nozzle passage (N) is made possible to spray while spreading evenly distributed state washing particles (W) do not gather in one place.

To this end, in the present embodiment, as the nozzle passage (N) is drilled in a rectangular shape as shown in FIGS. 3 and 4, the spraying area gradually expands while being discharged, and a plurality of branching protrusions (L) are formed therein. These are formed by the projections (L) are to be sprayed while spreading countless solid washing particles (W) uniformly distributed.

Each branch protrusion (L) may be formed in the form of a common column connecting the upper and lower surfaces as shown in Figure 3 in the nozzle passage (N), a plurality of nozzle passage (N) in the total area Are spaced apart at regular intervals (see Figure 4).

The branching protrusions L contact the countless solid washing particles W passing through the nozzle passage N, so that the particles W sandwich the protrusions L as shown in FIG. 4. The movement direction is changed to either side.

That is, the countless solid washing particles (W) passing through the nozzle passage (N) is injected in a state that is uniformly spread by the plurality of branching projections (L).

Each of the branch protrusions L may be formed of a polygonal pillar having a rhombus shape as shown in FIG. 4, and any one surface forming the polygonal surface is disposed in an inclined state without blocking the nozzle passage N. .

This structure is left and right with the inclined surface of each of the protrusions (L) while the countless solid washing particles (W) are moved along the nozzle passage (N), with each of the protrusions (L) in between It is sprayed while spreading smoothly.

If any one surface of each of the branch protrusions L is positioned to block the nozzle passage H, the countless solid washing particles W may not spread to the left and right sides, and the nozzle passage ( N) Stagnation may occur inside.

In addition, the nozzle passage (N) may be gradually narrowed up and down space while proceeding to the discharge side as shown in FIG. In this structure, the injection speed is accelerated when the pressure gas A passes through the nozzle passage N, thereby increasing the injection efficiency of the washing particles W.

In addition, the branching protrusions L contact the countless washing particles W passing through the nozzle passage N, in addition to the above-described action, and the washing particles W having a particle size of about 2 mm to 3 mm are approximately 0.5. It is to be sprayed in a shredded state of less than mm.

In this way, when the size of the washing particles (W) is injected in a small shredded state, the washing power is further increased. If the size of the washing particles (W) is sprayed in a state of 0.5mm or more particles, the washing particles (W) are not in contact with the surface to be washed and are not in contact with each other as they are bounced by the surface repulsive force and are not smoothly contacted. Excessive contact forces may deform or break the surface being cleaned.

In addition, the mounting unit 4 of the work vehicle 2 may be further provided with a fixing unit (U) for fixing in a state capable of changing the injection position and the injection direction of the injector (8).

As the fixing unit U, a conventional robot arm may be used as shown in FIG. 5, and the injector 8 is mounted as shown in the drawing to fix the injection position in at least one direction or more. .

Such a structure is a common feature of the fixed unit U, that is, the robot arm when cleaning the soundproof wall D while spraying solid washing particles W with the injector 8 during the movement of the work vehicle 2. Since the injection position and the injection direction of the injector 8 can be appropriately changed in the vertical direction or the horizontal direction by the joint motion, the entire surface of the soundproof wall D can be washed uniformly.

In the above description, the robot arm capable of articulation in the fixed unit U is used as an example, but is not limited thereto.

For example, as shown in Figure 6 is provided with a moving body M2 moving along the screw (M1) connected to the motor (M) axis, the connection section of the screw (M1) during forward and reverse rotation of the motor (M) In accordance with this can be used a conventional transfer unit for the reciprocating movement of the moving body (M2).

That is, the injector 8 may be mounted on the movable body M2 so that the injector 8 may be reciprocated along the connection section of the screw M1 so that the injection position is changed.

In addition to the above-described embodiments, the fixing unit U may be rotated and linearly moved to change the injection position and the injection direction of the injector 8 in the loading unit 4. Units having various structures can be used.

Therefore, the soundproof wall cleaning apparatus according to the embodiment of the present invention having the above-described structure moves along the soundproof wall D installation section by the work vehicle 2 as shown in FIG. 5 toward the soundproof wall D surface. (8) can be easily washed while spraying a myriad of solid washing particles (W).

In particular, the countless solid washing particles (W) injected by the injector (8), as well as cleaning the outer surface of the soundproof wall (D), but not shown in the drawing through the plurality of sound absorbing holes formed in the outer surface introduced into the interior Since it is vaporized after being in contact with the inner surface or the sound absorbing material, the interior space of the soundproof wall (D) can be washed.
