Description

Approach Pump-Driven Liquid Spreader {APPARATUS FOR SPRAYING A SNOW REMOVAL LIQUID IN PUMP DRIVING TYPE}

The present invention relates to a near-pump driven liquid spraying device, and more particularly, when the road condition is poor due to urban dust, yellow dust, and snow freezing on the road, it is necessary to operate a proximity pump installed on site. It is possible to apply the dispersant accurately and quickly to the target point to be sprayed.

In general, when snow accumulates or freezes on road surfaces with weak conditions such as bridges, curved curves, ascents, and entrances to tunnels, including straight roads, it may interfere with vehicle traffic and worsen road conditions. The same applies to dust accumulated on the road.

One way to clear and melt snow is to apply snow and snow thawing agents such as calcium chloride. In order to prevent slippage, a friction agent such as sand or granulated chips is applied.

In the spreading of various spreading agents, a simple spreading method is almost impossible to spread evenly on multi-lane wide roads, and there is a problem that causes traffic control and obstacles. There is a method of spraying mechanically using a spray vehicle, but there are many problems in traffic control and equipment operation.

The use of equipment and manpower-dependent snow removal and thawing work requires virtually no snow removal since equipment and manpower must be delivered to the site. For this reason, various methods have been studied.

Representatively, the technology of the 'snow plow spreading device on the road' of the Republic of Korea Patent Registration No. 225035, the 'road marker bottle with the spray function' of the Republic of Korea Patent Registration No. 750937 is known.

The above techniques are proposed to replace the spray spreading machine with mechanical spraying as a technique for preliminary repair and prompt treatment of roads requiring snow removal.

As shown in FIG. 1, a snow removing device for road snow removal is registered in Korean Patent No. 225035, which is connected to an installation chamber 10, a snow removal storage tank 11, a compression pump 12, and a compression pump 12. It consists of a dog injection hole 13, and installs the injection hole 13 so that it may have a predetermined height from the center line and the median of the road 14, or the edge road surface, and the snow removal agent is sprayed on the road surface. This technique is difficult to unify management because the spraying and dispensing means are separated. It is not useful as a road facility for simply spraying the necessary spraying agent on the road surface. Early operation is difficult because it is operated by direct operation. There are restrictions on the choice of installation location and no mobile installation is possible.

In addition, through the pumping pressure of the central compression pump 12 is sprayed through the injection holes 13 are arranged in several branches to distribute the snow removal agent to uniformly and stably remove the snow removal agent at a suitable injection pressure to a wide range of extended distance. There is a problem that cannot be injected. In particular, since the spraying type of the spraying agent depends on one central compression pump 12, the pumping pressure fluctuations are severe for each injection hole 13, and one compression pump 12 is used on roads such as curved roads and mountainous areas. It is impossible to apply when the operation error or fixing is difficult because it is difficult to respond to snow removal work.

As shown in FIG. 2, the snow removing device for road snow removal is a prop which is integrally installed at the lower part of the main body 20 to which the reflector plate 21 is attached and the main body 20 to support the main body. It is a road sign bottle comprising a fastening bolt that is fastened to the support through the 22 and the main body 20. The spray nozzle 23 connected to the liquid supply source 26 and the connector 24 is embedded in the inner space of the main body 20 so as to eject the liquid. The main body 20 is buried in the ground through the bracket 27 and is not separated from the outside to spray the contents of the liquid supply source 26 to the spray nozzle 23 through the pump 25.

This technology is installed in the center separator area and is floating, which can lead to nozzle clogging and breakage. There is a problem that early response is difficult because remote control of the injection timing is impossible. The liquid supply and the injection means are separated, so unified management is difficult, and there are many restrictions in the installation location selection. As it is mainly installed on urban roads, roads in mountainous and curved terrain are subject to usage restrictions.

On the other hand, since the liquid spraying device is installed in the form of leaving on the roadbed, more precise control is required according to the surrounding situation. For example, it was necessary to provide managers with information in real time, such as road condition information and current facility management status, in order to operate the liquid spraying device.

The 'liquid spreading device' of the Republic of Korea Patent No. 0985174, introduced by the applicant, has made it possible to respond early in snow removal through real-time remote control.

The above technology can be expected to operate the liquid spraying device by obtaining and transmitting a variety of information required for remote control operation, the current technology is the power control such as pump power control and pump driving by wired and wireless data communication.

In addition, the conventional liquid spreading device is impossible to reinstall and the movement is not free, so simple position adjustment or change is impossible. And there is a problem that can not be reused repeatedly.

The present invention was devised to improve the problems of the prior art, and when the road condition is poor due to urban dust and yellow dust and snow freezing on the road surface, the proximity pump disposed around the road is operated. The purpose is to enable the application of the dispersant accurately and quickly to the target point of application.

Another object of the present invention is to remotely control the liquid spreading device installed on the site in real time.

Proximity pump driven liquid spreading device according to the present invention for achieving the above object,

Proximity pump-driven liquid spraying apparatus according to the present invention, the sub-pump 160 that can directly spray the road spraying agent 500 road surface along the poor road environment can be installed and operated freely along the periphery of the road 500 Can be.

In spraying the spraying agent onto the road surface 500, the desired liquid spraying agent may be uniformly distributed through the adjacent subpumps 160 without changing the spraying pressure of the spraying agent through the respective subpumps 160 arranged at the shortest distance of the road surface. It is possible to spray on the road surface 500, it can be sprayed effectively to the target point stably.

In general, problems common to spraying liquid spreading agents on the road, such as using a single central pump to spray the spreading agent through several spray nozzles, result in insufficient pumping pressure and high altitude and mountainous terrain. Effective spraying of sprays on road surfaces was difficult. In particular, it was impossible to apply winter ice or snowplow, and the management of spraying was difficult.

The present invention is a sub-pump 160 organically arranged according to road conditions and conditions of the road 500 separately from the main pump 140 to discharge the spraying agent 100 from the storage tank 120 side storing the spraying agent 100 Through), the spraying position of the spraying agent can be designed and planned to be operated according to the road 500 conditions.

That is, the spraying agent can be sprayed over a wide range of areas with a uniform spray pressure without satisfactory spraying conditions, including a curved road 500, a straight road 500, and the like.

When the main pump 140 is driven, the liquid spraying agent 100 contained in the storage tank 120 at the popping pressure is discharged through the connection pipe 130.

The spraying agent 100 is discharged through the distributor 170 through the extension pipe 150. The spraying agent 100 reaches the sub-pump 160 side along the pipe 180 through the distributor 170 disposed in place of the extension pipe 150 at the pumping pressure through the main pump 140.

The spraying agent 100 that reaches the sub-pump 160 is limitedly sprayed through the nozzle 190 according to the pump driving power.

At this time, since the sub-pump 160 is arranged in advance according to the condition and conditions of the road 500, the spraying agent is sprayed onto the road surface of the road 500 according to the driving power control of the sub-pump 160. Not much control.

An important point in the spraying of the spraying agent through the sub-pump 160 is that the injection pressure can be sufficiently secured. That is, the sub-pumps 160 may be disposed in accordance with the road 500 conditions, and spraying may be performed on a desired area, and in this process, spraying of the spraying agent may not appear due to a drop in spraying pressure or uneven pressure drop.

As described above, the proximity pump-driven liquid spraying device according to the present invention diverges the spraying agent 100 from one storage tank 120 containing the spraying agent 100, and requires a branching spraying agent 100 without pressure drop. Efficient and planned spraying of dispersant is possible.

From controlling the driving power of the main pump 140 and the sub-pump 160, whether or not the spraying agent is sprayed can be remotely controlled in real time. Here, the direct power control by the manager is related to the power switch on / off, so a detailed description thereof will be omitted.

The present invention is capable of remote control for the main pump 140 and the sub-pump 160 constituting the liquid spraying device. That is, the real-time control is possible by connecting the remote terminal device 400 through the wired / wireless communication network 300.

The remote terminal device 400 may be connected to the wired / wireless communication network 300 to access the remote terminal device 200 in real time through the data communication unit 210 of the proximity pump driven liquid spray device installed in the field. In the case of a wireless communication network, real-time access is possible through a smartphone.

The controller 230 may check whether the connected administrator is allowed to access, and if the access manager is not an authorized administrator, block the access and allow the authorized administrator to access.

When an administrator allowed to connect transmits data through a remote terminal device 400 such as a smartphone, the central processing unit (CPU) of the remote terminal device 200 is driven by the transmitted data value to output data values. By driving the main pump 140 and the sub-pump 160 installed in the field to spray the spraying agent 100 through the nozzle 190 or to stop the operation of the main pump 140 and the sub-pump 160 to the spraying agent ( The injection of 100) can be stopped.

Here, it is also possible to selectively drive only the sub-pump 160 required through the individual power control for the plurality of sub-pump 160.

As such, the present invention determines whether the spraying agent 100 is sprayed according to whether the main pump 140 and the sub-pump 160 are driven. In the process, the detection information may be transmitted to the administrator through the wired / wireless communication network 300 by comparing the data input / output values that are stored and set in the central processing unit (CPU) and the memory of the remote terminal device 200.

In this way, the user can check the contents displayed on the remote terminal device 400 such as a smartphone by checking the transmitted data value, and determine whether to continue the execution according to the abnormality, and collect the collected information from the remote terminal. Acquired through the device 400 to grasp the state of the overall liquid spreading device, and can selectively transfer control commands for each functional unit through the controller 220, and transmits the processing result and data to the remote terminal device 400 You can get feedback and save the results.

The control command executed through the controller 220 is integrated with a microprocessor or a microcomputer included in the control unit 230 of the remote terminal device 200 receiving the transmission data of the remote terminal device 400 through the data communication unit 210. Central control unit (CPU) having a control function, PLC for controlling the driving power of the main pump 140 and the sub-pump 160 in accordance with a programmed command input to the data of the remote terminal device 400, from each pump It is executed sequentially through the RTU that collects and compares the output data.

The remote terminal device 200 receives the data signal transmitted from the remote terminal device 400 through the wired / wireless communication network 300 in real time through the data communication unit 210 and the control unit 230 of the remote terminal device 200. The sub-pump 160, including the main pump 140, is controlled through the CPU to store the data and output the data signal value.

The wired / wireless communication network 300 may use a wireless communication network, for example, a communication network established by commercial mobile carriers (SKT, KT.LG) compared to wired communication, and may include a LAN, other wired / wireless communication networks, Wi-Fi and 3 Applications such as 4G networks can be utilized. The data signal processing format may be operated by selecting various wireless data transmission / reception formats such as CDMA / ZIGBEE, and may be controlled through the remote terminal device 400. That is, it is possible to utilize various wireless communication services using wireless wired and wireless communication networks of computer, electronic and communication technology.

5 is a block diagram schematically illustrating a relationship between a communication terminal, which is one of the models of the remote terminal device 400, connected to the remote terminal device 200.

The message transmitted to the remote terminal device 200 installed in the field may be transmitted in a basic short sentence form to be read and driven or may be a specially encoded program command.

For example, after the road surface condition situation determination process, the snow removal work is pre-determined, and the administrator transmits the data by a method such as a specific data code value through a wired / wireless communication network, and the data of the remote terminal device 200 installed at the site. Whether to drive the main pump 140 and the sub-pump 160 according to a predetermined algorithm received by the communication unit 210 and recognized by the control unit 230, or to drive the drive, or the drive signal through the controller 220. Control whether to pass or to obtain information by comparing with the input value.

The data communication unit 210 corresponds to a part for receiving a transmission signal sent by an administrator who owns the remote terminal device 400.

Proximity pump-driven liquid spreading apparatus of the present invention is capable of controlling the spraying of the spraying agent through remote control of the pump driving in real time according to the situation determination of the manager, and at the same time of the control unit 230 constituting the remote terminal device 200 It is also possible to set the injection condition and set an arbitrary time-check the operation-automatic data transmission-automatic operation by pump driving.

Along the curve of the curved road 500, as shown in Figure 6 can be installed in a variety of types, such as in series and parallel in a number of sub-pumps 160, it is installed in a place difficult to manage and operate the spreading device in general, such as high ground It is possible.

In addition, it can be effectively used by installing on the edge of the road that does not interfere with vehicle traffic on the basis of the installation facility, and by freely determining the position at the pre-computed position along the curve to enable intensive snow removal and thawing on curved roads. Since the spraying pressure of the spreading agent can be adjusted and arranged, the snow removal can be effectively performed at an optimized position when installed for snow removal and thawing purposes.

In addition, the mobile installation is free. It is also possible to increase safety by installing at an optimized location by securing the location based on sufficient pre-simulation for the road conditions and adjusting the installation location. This can be solved by the coupling and disassembly of the extension pipe 150, the distributor 170, and the sub-pump 160, and the problem of re-installation of other liquid spreading apparatuses, which is generally compared, can be freely moved and simply adjusted and changed. It is possible.

And it can be reused repeatedly, and it can reduce the occurrence of safety accidents due to the exposure of parts and wiring, and even in the case of relocation, complicated wiring is not necessary, so handling and construction are good.
