The present invention relates to an unmanned automatic spraying device for preventing freezing of roads in winter, and more particularly, to effectively perform snow removal and thawing work on shady roads or steep hills and sharp curve areas that are susceptible to freezing snow or cold in winter. It relates to an unmanned automatic spreading device that can be.

In general, when it snows or freezes during the winter months, especially snowfall or freezing on roads such as bridges, curves, uphills, and entrances to tunnels, it is likely to cause enormous embellishment of traffic. In addition, the risk of safety accidents increases, so snow removal or thawing should be done quickly.

Conventional methods for removing snow on roads or thawing roads include spraying snow removal agents such as calcium chloride, thawing agents or friction materials such as sand on the road, or performing snow removal operations using snow removal vehicles such as scrapers. There is a way.

However, such a conventional method should use an automobile or the like and spray snow-removal agent or thawing agent by hand, and thus, there is a problem in that enormous manpower and equipment are required and workability is also deteriorated.

In addition, when heavy snow falls, snow accumulates rapidly on the road surface. However, if the snow removal is not performed quickly, the snow traffic is paralyzed and the risk of traffic accident increases. There was a problem that can not properly cope with the situation that requires a rapid snow removal, such as heavy snow.

In addition, in a relatively wide section of the road, it is difficult to perform the snow removal evenly in each lane by the conventional method, when performing the snow removal, to control or restrict the traffic of the vehicle for the safety of the workforce There was a problem that should be.

In addition, performing the snow removal work at a time such as late at night or dawn acts as a large workload for the worker, there was a problem such as a variety of work safety accidents that occur.

In order to solve this problem, a method of spraying a snow removing agent as a dedicated spray truck has been proposed.

However, this method has the effect of reducing the manpower, but the dedicated spray truck is quite expensive, there was a problem that can not fundamentally solve the above problems.

Particularly, in case of heavy snowfall, it is difficult for the dedicated spraying vehicle itself to enter freezing roads such as bridges, curves, uphills, tunnel entrances, etc., which makes it difficult to quickly remove snow, and during snow removal, safety of other vehicles passing through There was still a problem of controlling or restricting vehicle traffic.

In addition, when a large amount of snowfall occurs in a specific area due to rapid weather changes, local governments, road construction, etc., which are the principals of snow removal, face the situation of putting their own equipment into snow removal work on large roads, main roads, etc. Snow removal work is delayed on the main roads and mountain roads, and thus securing the safety of vehicle traffic has become a serious problem on these relatively weak roads.

As another method to improve this, a sea ice solution for fixing or embedding a spray nozzle for spraying sea ice solution on one side or the center of the road, and performing snow removal or thawing on the road surface by spraying the solution at high pressure through the nozzle. Injectors have been proposed.

However, since the injection device is a method of injecting a solution by the injection nozzle, the nozzle may be frequently clogged or the corrosion may occur in the conduit and the spray head, etc., when foreign matter is not used during the winter season due to the foreign matter getting stuck in the nozzle inlet. There is a problem, such as, because the injection device is fixed or embedded on the road, there was a problem in that the replacement work when the parts are difficult to replace.

In addition, the injector as described above, the solution such as thawing liquid is transported through a pipe using a compression pump from a solution reservoir located in a certain place, and spraying the transferred solution through a fixed or buried injection nozzle on the road Since it is a method, the overall size of the system is increased, thereby increasing the installation cost and installation cost, there was a problem that it takes a considerable time when installing.

The present invention has been made in order to solve the problems of the prior art as described above, by installing in places such as rugged mountain roads, sharp curves, bridges, etc. in preparation for the severe and sudden heavy snowfall, such as late night, dawn, freeze-resistant spraying work The purpose of the present invention is to provide an unmanned automatic spreading device that can reduce costs by minimizing the cost of manpower and equipment, and reducing costs.

The sensor 20, like the control panel 10, is installed on the outer wall of the spreading device 100 or in a suitable place spaced apart from the spreading device 100.

The sensor 20 measures the temperature of the road on which the sprinkling apparatus 100 is installed, and preferably, the surface temperature, the atmospheric temperature, and the humidity of the road. The measured data is transmitted to the control unit 30 and processed.

Meanwhile, as illustrated in FIG. 1, the storage unit 40, the discharge unit 50, and the spraying unit 60 are located at the top, the center, and the bottom of the spraying device 100, respectively. That is, the storage unit 40 is located in the upper portion of the spraying apparatus 100, the spraying unit 60 is located in the lower portion of the spraying apparatus 100, the discharge unit 50 is the storage unit 40 It is located between and the spraying unit 60.

The storage unit 40 includes a hopper 42 which stores a snow removing agent or a thawing agent (hereinafter, referred to as 'drug'); Located at the top of the hopper 42 is composed of a hopper cover 41 for opening and closing the hopper 42.

The hopper 42 is formed in the form of a funnel gradually narrowing downward, so that the stored medicament can be introduced to the lower side of the hopper 42 well.

This can ensure the strength to withstand the vibration by the spraying operation of the spraying unit 60 to be described later, excellent waterproofness and can prevent the drug stored therein from being exposed to moisture, as described above It is because it is easier also in shape | molding the shape of (42) to funnel shape.

As for the volume of the said hopper 42, about 0.2 m <2> which is about enough to put 5 chemical | medical bags of 25 kg, for example is suitable.

On the other hand, the discharge unit 50, the stirring blade 51 for stirring the medicine stored in the hopper 42; A stirring blade rotating shaft 54 for rotating the stirring blade 51 while being rotated by a motor 64; A discharge port 52 formed at the bottom of the bottom of the hopper 42 so that the medicine is discharged from the hopper 42 to the spraying unit 60 described later; It is configured to include a discharge port shutter 53 which is provided directly below the discharge port 52 to open and close the discharge port 52.

The stirring blade 51 is located directly above the bottom of the bottom of the hopper 42, is connected to the stirring blade rotary shaft 54 is rotated by the motor (64).

Since the medicine stored in the hopper 42 is agitated by the rotation of the stirring blade 51, the amount of the medicine discharged from the discharge port 52 becomes uniform, and thus, in the spraying unit 60 to be described later. The spreading amount of is uniform.

In addition, the discharge port shutter 53 may perform the opening and closing operation of the discharge port 52 by a sliding method from the inner wall surface of the sprinkler, in some cases coupled to the stirring blade rotating shaft 54 to interlock In an embodiment, the opening and closing operation of the discharge port 52 may be performed by a rotation method.

In this case, the controller 30 controls the operation of only one motor 64, thereby simultaneously controlling the discharging operation of the discharge unit 5 and the spraying operation of the spraying unit 60, and the motor ( Since only 64 is needed, there is an advantage that the whole structure can be simplified.

On the other hand, the discharge port 52 is preferably formed at the bottom of the lowermost end of the hopper 42, one each left and right around the stirring blade rotation axis 54.

In addition, the spinners 61 correspond to the pair of discharge ports 52, and are positioned one by one on the left and right sides of the stirring blade rotation shaft 54, and the respective spinners 61 are opposite to each other. By rotating at a high speed in the direction, the medicine discharged from the discharge port 52 is sprayed to the outside of the spreading apparatus 100.

The position of the discharge port 52, in relation to the position of the spinner 61 of the spraying unit 60 to be described later, plays a very important role in determining the spraying range and the spraying distance of the drug.

For example, as shown in Figure 3, when the pair of discharge ports 52 is located in a wide spread form on the left and right sides of the stirring blade rotating shaft 54, the spraying range of the drug sprayed by the spinner 61 is At the same time, the spreading distance is shortened.

On the other hand, when the pair of discharge ports 52 are located in the form of gathering toward the direction in which the drug is sprayed around the stirring blade rotating shaft 54, the spraying range of the drug sprayed by the spinner 61 is At the same time, the spreading distance becomes longer.

Therefore, by forming the pair of discharge ports 52 in a proper position, it is possible to adjust the spraying range and the spraying distance of the drug, and in some cases, to form a pair of discharge ports 52 in various positions, the spreading device In consideration of the width and the like of the road where the 100 is installed, it is also possible to control such that only a few pairs of the discharge ports 52 can be opened.

In addition, by forming a plurality of pairs of the discharge port 52 in various positions, and by opening only a few pairs of the discharge port 52 of the several asymmetrically located discharge port 52, to control the spraying direction It is also possible.

In addition, it is also possible to continuously control the change in the spraying direction by forming a plurality of pairs of discharge ports 52 at various positions, and continuously opening and closing some pairs of the discharge holes 52.

On the other hand, the spraying unit shutter 65 is installed in the direction in which the drug is sprayed to the outside by the spinner 61, is located on the outer wall surface of the spraying apparatus 100, the spinner 61 by sliding in the vertical direction ) To prevent exposure to the outside.

In addition, the obstacle detection sensor 80, like the control panel 10 is installed on the outer wall of the spreading apparatus 100 or in a suitable place spaced apart from the spreading apparatus 100.

The obstacle sensor 80 detects the presence or absence of a person or a vehicle on the road on which the spraying operation is performed by the spraying apparatus 100, and the result is transmitted to the controller 30 and processed.

The power supply unit 90 is a portion that provides power to the spraying device 100, and by using a rechargeable battery that can be attached and detached, the spraying device 100 according to the present invention can be easily disposed at a suitable place. And removal can also be facilitated.

On the other hand, the control unit 30, the overall control of the operation of the spraying apparatus 100 according to the present invention, is mounted inside the spraying apparatus 100.

As shown in FIG. 2, the controller 30 includes a control panel 20, a sensor 20, a discharge unit 50, a spray unit 60, a warning unit 70, and an obstacle detecting sensor 80. It is electrically connected to and exchanges control signals, receives a set value from the sensor 20 and the obstacle detection sensor 80 from the control panel 10, the discharge unit (3) by a predetermined control method. 50), the operation of the spraying unit 60 and the warning unit 70 is controlled.

4 and 5, a control flowchart of the control unit 30 is shown.

4 is a control flowchart of the controller 30 when the obstacle detecting sensor 80 is not included.

First, the control flow of the controller 30 will be described with reference to FIG. 4.

Dividing the control step of the control unit 30 into large, i) setting value input step (S1) in order; Ii) present value input step S2; Vi) a comparison step (S3, S4); Viii) the spraying operation start step (S5, S6); Vi) can be divided into five stages of the spraying operation stop step (S7, S8).

First, in the setting value input step S1, the controller 30 receives a setting value such as a spraying time zone t and a setting temperature k from the control panel 10.

The spraying time zone t, the set temperature k, and the like are preset values through the key operation unit 12 of the control panel 10, and the spraying time zones a ≦ t ≦ b, a: start time, b: End time), for example, "04:00-06:00, 17:00-20:00" can be set to some time zone of a certain interval, the set temperature (k) is, for example, "external standby" Temperature -3 ° C ".

In addition, it is possible to further set variables such as surface temperature of the road, external humidity, and the like as the set value.

In the next present value input step (S2), the present time (T) is input from the built-in clock, and the atmospheric temperature (K) of the current outside is received from the sensor (20).

The sensor 20 inputs the measured value to the control unit 30 with respect to such a variable when a variable such as a surface temperature of the road, an external humidity, etc. is added in addition to the external atmospheric temperature.

In the next comparison step (S3, S4), the present time (T) received as a current value from the built-in clock, the range of several types of spraying time (t) received as a set value from the control panel 10 Judging whether to enter (a ≦ T ≦ b) (S3); Determining whether the current external atmospheric temperature (K) input as the current value from the sensor 20 is lower than the set temperature (k) input as the set value from the control panel 10 (K≤k) ( S4).

If the current time (T) falls within the range of the spraying time zone (t), which is the set value (a≤T≤b), and the current outside atmospheric temperature (K) is lower than the set temperature (k), which is the set value ( K≤k), and moves to the next spreading operation start step (S5), if any of the two conditions are not satisfied, return to the initial step (the previous step of the set value input step) and repeat the above steps Done.

When entering both the spraying operation start step (S5) to satisfy both of the above conditions, the control unit 30, after opening the spraying unit shutter 65 and the discharge port shutter 53, the spinner 61 and the stirring blades Rotate 51. At this time, if the spinner 61 and the stirring blade 51 is coupled to the motor 64, the controller 30 can control the start of the spraying operation by controlling the rotation of the motor (64).

After the spraying is continued for a predetermined time, for example, for 10 seconds (S6), when the spraying operation stop step (S7) is entered, the controller 30 stops the rotation of the spinner 61 and the stirring blade 51, and spreads. The sub shutter 65 and the discharge port shutter 53 are closed.

When the spraying operation is stopped, the air is returned to the initial stage (the previous stage of the set value input stage) after waiting for a predetermined time (S8), and the above steps are repeated again.

5 is a control flowchart of the controller 30 when the obstacle detecting sensor 80 is additionally included.

The operation flow of each step is generally the same as in FIG. 4, but before entering the spraying operation start step S5, it is determined whether a person or a vehicle is detected by the obstacle sensor 80 on the road on which the spraying operation is to be performed. Step S45; After entering the spraying operation start step (S5), a step (S56) of determining whether a person or a vehicle is detected by the obstacle sensor 80 on the road to be sprayed operation is different is added.

That is, when each condition of the comparison steps S3 and S4 is satisfied, it is determined whether a person or a vehicle exists on the road on which the spraying operation is to be performed before starting the spraying operation (S45).

If the presence of a person or a vehicle is detected, the process returns to the initial stage (the previous stage of the set value input stage) after waiting a predetermined time (S451) and repeats the above stages. At this time, the controller 30 may generate an alarm using the buzzer 71, the warning lamp 72, or the like of the warning unit 70, so that a person or a vehicle on the road can move quickly.

On the other hand, if the presence of a person or vehicle is not detected, the spraying operation is started (S5), the spraying is continued for a predetermined time.

However, if the presence of a person or vehicle is detected after the spraying operation is started, the spraying operation is stopped (S7), and after waiting for a predetermined time (S8), the initial stage (previous step of the set value input step) Returning to, the steps are repeated from the beginning.

As described above, the control of the sprinkling apparatus 100 according to the present invention arbitrarily sets the temperature change, the sprinkling time and the like according to the expectations of the operator, and compares the set values with the present values measured by the sensors. It is possible to take the unmanned automatic spraying method to spray the medicine automatically under the proper conditions by judging, and the manual spraying method by the direct operation of the operator is also possible.

In addition, the integrated spray method according to the main control management method for integrally controlling all the equipment of a certain number or a certain area through wireless communication is also possible.
