In the driving space 1010, a seat in which a driver and a driving assistant can ride may be arranged, and a control device 1800 may be arranged around a seat in which the driver assistant rides.

The control device 1800 may control sprinkling-related devices included in the sprinkling wheel 1000. For example, the control device 1800 can control the opening and closing of the transport pipe 1600 by operating a number of switchgear (1660, 1670, 1680, 1690) included in the aqueous pipe (1600), and the water spray device (100). ) You can control the spray direction.

A driving space 1010 may be disposed in front of the sprinkler 1000, and a tank 1020 may be disposed in the rear.

A fluid may be stored in the tank 1020. The fluid may be water at room temperature, or a solution in which a special substance is dissolved. For example, the fluid may be brine in which sodium chloride, potassium chloride, or the like is dissolved, and a disinfectant may be dissolved or a fire fighting agent may be dissolved.

The tank 1020 may be made of stainless steel on the inside. Due to these materials, even if a solution in which special substances are dissolved is stored, the interior may not be corroded.

A pump 1700 may be disposed inside the tank 1020 or at the periphery of the tank 1020. The pump 1700 may pressurize the fluid stored in the tank 1020 to output the high-pressure fluid to the transport pipe 1600.

As an example, the pump 1700 may receive driving force from the engine of the sprinkler 1000. The pump 1700 may be operated by receiving a driving force from a power take out (PTO) device connected to the transmission of the sprinkler 1000.

As another example, the pump 1700 may be operated by receiving power from an internal power source of the sprinkler 1000-for example, a battery or a generator, and has its own controller or a battery to receive power. Can be used, and the two power supply methods described above can be used in combination.

The pump 1700 may output a high-pressure fluid through the transport pipe 1600. In addition, the transport pipe 1600 may supply a high-pressure fluid to devices disposed in front, rear, side, and upper through a plurality of transport pipes 1610, 1620, 1630, and 1640.

The transport pipe 1600 may include a distribution pipe 1650, a first transport pipe 1610, a second transport pipe 1620, a third transport pipe 1630, and a fourth transport pipe 1640. The transport pipe 1600 may be formed of stainless steel inside to prevent corrosion by a solution in which a special material is dissolved.

The distribution pipe 1650 includes a plurality of connectors, one connector may be directly connected to the pump 1700, other connectors may be connected to the transport pipes (1610, 1620, 1630, 1640).

The connectors may include a switchgear. The first connector includes a first switch (1660), the second connector includes a second switch (1670), the third connector includes a third switch (1680), and the fourth connector includes a fourth switch ( 1690) may be included.

It may be connected to the tube 1640.

The first transport pipe 1610 may transport the fluid delivered from the distribution pipe 1650 forward. The first transport pipe 1610 may be disposed under the vehicle frame in front where the driving space is formed. Such an arrangement may be an arrangement that facilitates manufacture of the sprinkler 1000 without causing a separate deformation on the vehicle frame. However, according to this arrangement, since the piping path is low, it may be a factor of lowering the injection port of the water spray device 100 disposed in front. Referring to the contents to be described later, in order to solve this problem, the sprinkling apparatus 100 according to an embodiment uses a method of raising and lowering the fluid delivered in a low path upward through a U-shaped pipe. As a result, the height of the left and right rotation pipe and the vertical rotation pipe can be raised, and the injection port can be placed in an optimal position.

The second transport pipe 1620 may transport the fluid delivered from the distribution pipe 1650 upward. The second transport pipe 1620 may be disposed along the outer periphery of the tank 1020 while being fixed to the front frame of the tank 1020 through a separate fixing device.

A tarpaulin 1300 may be connected to the end of the second transport pipe 1620, and the cross-sectional area of the fluid path from the pump 1700 through the distribution pipe 1650 to the second transport pipe 1620 is the same or less- The pressure of the fluid output from the pump 1700 may be transmitted to the tarpaulin 1300 as it is while having a difference of similar ranges. The tarpaulin 1300 may perform high-pressure long-distance watering using this pressure.

The third transport pipe 1630 may transport the fluid delivered from the distribution pipe 1650 to the side. A side sprinkler 1400-for example, a fire protection water pipe-may be connected to an end of the third transport pipe 1630.

The end of the third transport pipe 1630 and/or the third switch 1630 may be disposed within a range of 1m to 1m50cm from the ground, so that the fastening of the side sprinkler 1400 and manual operation of the third switch 1630 It can be easy. In addition, the end of the third transport pipe 1630 may be positioned within the shortest path to the pump 1700 compared to other transport pipes, and the high-pressure fluid output from the pump 1700 may be delivered in a state in which pressure loss is minimized.

The fourth transport pipe 1640 may transport the fluid delivered from the distribution pipe 1650 to the rear.

A rear sprinkler 1500 may be connected to an end of the fourth transport pipe 1640. The rear sprinkler 1500 includes a plurality of nozzles, and a fluid may be dispersed and output through these nozzles. Each nozzle can inject fluid in a backward-downward-backward and downward-facing direction-, and the total cross-sectional area of the output ports of the plurality of nozzles is larger than the cross-sectional area of the fourth transport pipe 1640. Can be sprayed. A plurality of nozzles may be disposed in parallel with the ground in a direction perpendicular to the direction of travel of the sprinkler 100.

A fixed frame plate (see 120 in FIG. 4) may be coupled to the vehicle frame in front. The fixed frame plate (see 120 in FIG. 4) may be included in the sprinkling device 100 or may be provided separately.

A U-shaped groove may be formed on the upper side of the fixed frame plate (see 120 in FIG. 4), and a snow shovel 1200 may be coupled to the groove. The side of the snow shovel 1200 may be viewed as a C-shaped curve, and the front may be viewed in a rectangular shape. The snow shovel 1200 may be disposed so that the lower edge has a predetermined minimum height from the ground.

When the snow shovel 1200 is coupled to the fixed frame plate (see 120 in FIG. 4), salt water may be sprayed through the rear sprinkler 1500. For example, the snow removal shovel 1200 removes snow of a certain thickness or more from the road from the front of the vehicle, and salt water is sprayed from the rear to the snow remaining on the road, thereby making perfect snow removal.

3 is a front view of a control device according to an embodiment.

Referring to FIG. 3, the control device 1800 may include a switch panel 1850 and position manipulators 1810 and 1820. A plurality of switches 1831 to 1836 for controlling opening and closing of a pipe may be disposed on the switch panel 1850.

The first switch 1831 can open and close one of the pipes in fluid communication with the spray hole on the left side of the sprinkler device (see 100 in FIG. 4), and the second switch 1832 is a sprinkler device (see 100 in FIG. 4). One of the pipes in fluid communication with the injection port on the right side can be opened and closed.

The third switch 1833 may control fluid supply to the rear sprinkler by operating a fourth switch (see 1690 in FIG. 2) connected to the fourth transport pipe (see 1640 in FIG. 2). In addition, the fourth switch 1834 may control the supply of fluid to the tarp by operating a second switch (see 1670 in FIG. 2) connected to the second transport pipe (see 1620 in FIG. 2 ). In addition, the fifth switch 1835 may control the supply of fluid to the side sprinkler by operating a third switch (see 1680 in FIG. 2) connected to the third transport pipe (see 1630 in FIG. 2).

The sixth switch 1836 may control opening and closing of a pipe related to fluid injection into the tank. The pipe through which the fluid is injected into the tank may be connected to the distribution pipe, directly connected to the pump, or directly connected to the tank. When the pipe through which the fluid is injected into the tank is directly connected to the pump, the pump can transfer the external fluid to the tank. The pump may have an input port and an output port. When the input port is connected to the tank and the output port is connected to a transport pipe, the fluid stored in the tank may be output to the transport pipe. Alternatively, when an external fluid-a fluid in which the tank is located outside-is connected to the input port of the pump, the pump may pressurize the external fluid and send it out to the output port. According to this function, the pump may be operated as a water pump. When the pump is driven by engine power, the pump can have a pumping capacity of 1500 (liters/minute).

The positioning devices 1810 and 1820 may have a joystick shape, and the left and right rotation motors of the water spraying device (refer to 100 in FIG. 4) to be described later are driven according to left and right manipulations, thereby rotating the injection port left and right. Accordingly, while the vertical rotation motor of the sprinkling device (see 100 in FIG. 4) is driven, the injection port can be rotated vertically. The position manipulators 1810 and 1820 may control the motor in the forward and reverse directions through +/- power on/off control of the vertical rotation motor or the left and right rotation motor of the water spray device (see 100 in FIG. 4). For example, the positioning devices 1810 and 1820 can supply + voltage to the left and right rotation motor to rotate the left and right rotation motor of the sprinkler (refer to 100 in FIG. 4) to the left and-voltage to the left and right rotation motor to rotate right. have. In the same concept, the position control unit (1810, 1820) supplies + voltage to the vertical rotation motor to rotate the vertical rotation motor of the sprinkler (refer to 100 in Fig. 4) upward, and to the vertical rotation motor to rotate downward. Can supply.

The sprinkling device 100 may have a structure of a symmetrical type as a whole. Here, the direction is determined based on the gaze of the driver in the vehicle, the left side is the driver's left hand direction and the right side is the driver's right hand direction. Further, the front is the vehicle forward direction, the rear is the vehicle backward direction, the upper direction is the direction away from the ground, and the lower direction is the direction toward the ground. Hereinafter, the description will be mainly focused on the left half of the sprinkling device, but the same structure may constitute the right half of the sprinkling device.

The inlet pipe 110 may have a solid structure while being made of a metallic material. The inlet pipe 110 may be coupled to the vehicle frame through a separate fastening member-for example, a bolt-or by a coupling method such as welding.

The inlet pipe 110 may have a'T'-shaped structure, and according to this structure, a high-pressure fluid flowing into the center may be circulated in left and right directions.

The fixed frame plate 120 is indicated by a dotted line in the drawing for convenience of explanation. However, in the product, when viewed from the front while the vehicle is disposed more forward than other components, some of the other components are attached to the fixed frame plate 120. Can be seen obscured by

The fixed frame plate 120 may have a rigid structure coupled to the vehicle frame-for example, a structure made of a metallic material or a structure made of a reinforced plastic material. The fixed frame plate 120 may be coupled to the inlet pipe 110 through a first fastening member 121-for example, a bolt-in order to increase the coupling force with the vehicle. To this end, a coupling plate (not shown) extending from the pipe body is formed in the inlet pipe 110, and the coupling plate (not shown) and the fixing frame plate 120 may be fastened in a screw/bolt structure.

The fixed frame plate 120 may have a rectangular shape as a whole, but may have a partially cut shape. For example, U-shaped grooves 122 may be formed on both left and right sides at the upper edge of the fixed frame plate 120, and a snow shovel may be seated in the groove 122. When the snow shovel is coupled, the fixing frame plate 120 may provide a coupling structure in which the snow shovel can be fixed to the vehicle, and may provide a front and rear support for the snow shovel.

A first pipe connection part 220 may be located between the inlet pipe 110 and the upper induction pipe 130. In the first pipe connection part 220, a thread formed on the outside of one end can be combined with a thread formed on the inside of the inflow pipe 110, and a thread formed on the outside of the other end is formed inside the upper induction pipe 130 It can be combined with a screw thread. And, at the ends of the inlet pipe 110 and the upper induction pipe 130, a coupling plate extending further outward than the cross section of the pipe body is formed, and the coupling plate of the inlet pipe 110 and the upper induction pipe 130 While being fastened with a screw/bolt structure, it is possible to increase the coupling force between the inlet pipe 110 and the upper induction pipe 130.

The fixed frame plate 120 may have a'U'-shaped cutting portion so that the first pipe connection portion 220 is exposed to the outside. According to this structure, it is possible to easily access the first pipe connection unit 220 from the outside and facilitate replacement and installation.

The upper induction pipe 130 may guide the fluid delivered from the inflow pipe 110 upward through the first curved pipe 131 bent at 90 degrees. The sprinkling apparatus 100 according to an embodiment configures a fluid flow path for guiding the fluid upward and then returning it downward. According to this configuration, it may be easier to rotate the pipe left and right.

The U-shaped pipe 140 may include a U-shaped portion 142 and a straight portion 141, 143, and the straight portions 141 and 143 may have a relatively solid material compared to the U-shaped portion 142. Alternatively, the U-shaped portion 142 and the straight portions 141 and 143 may be formed of the same material.

The U-shaped pipe 140 performs a function of returning the fluid that has been guided upward again to the downward direction.

The fixed pipe 150 is in fluid communication with the U-shaped pipe 140 and may be coupled to the fixed frame plate 120 through a second fastening member-for example, a bolt. Since the U-shaped pipe 140 includes a portion made of a flexible material, the fixed pipe 150 may perform a function of stably supporting the U-shaped pipe 140. Since the fixed pipe 150 is coupled to the fixed frame plate 120 and the fixed frame plate 120 is coupled to the vehicle frame and/or the inlet pipe 110, the fixed pipe 150 is supported by the vehicle frame. do. And, since the fixed pipe 150 supports the U-shaped pipe 140 from both sides together with the upper induction pipe 130, it is possible to maintain a stable shape even though the U-shaped pipe 140 is composed of a flexible material.

The first bearing unit 160 may be positioned under the fixed pipe 150. In addition, the left and right rotation pipe 180 may be bearing-coupled with the fixed pipe 150 through the first bearing unit 160.

The upper part 181 of the left and right rotation pipe 180 may have the same height as the inlet pipe 110 or a height higher than the inlet pipe 110. This is possible because the watering device 100 is a U-shaped pipe 140 This is because it has a structure in which the fluid is guided upward and then returned downward.

A chain coupling structure may be formed along the outer surface of the upper part 181 of the left and right rotation pipe 180, and may be chain-connected to the left and right rotation motor 170 through this chain coupling structure.

The left and right rotation motor 170 has a body fixed to the support plate 171, and the support plate 171 may be fixed to the fixed pipe 150 and/or the upper induction pipe 130. According to this fixing structure, the left and right rotation motor 170 may receive a support force from the vehicle frame.

The left and right rotation motor 170 may rotate the left and right rotation pipe 180 using a chain. The central axis of the left and right rotation motor 170 is disposed in a direction perpendicular to the first plane, and the chain may move in the first plane according to the rotation of the central axis and the left and right rotation pipe 180 may be rotated.

A second bearing part 190 may be positioned on one side of the left and right rotation pipe 180. In addition, the vertical rotation pipe 200 may be bearing-coupled with the left and right rotation pipe 180 through the second bearing part 190.

The vertical rotation pipe 200 may rotate in a second plane perpendicular to the first plane. If the first plane is a plane including front, rear, leftward, and rightward, the second plane may be a plane including front, rear, upper, and lower sides.

The vertical rotation pipe 200 may be rotationally controlled by the vertical rotation motor 240.

In addition, the second end 253 of the rotational power transmission rod 250 may rotate along a circumference formed around a central axis of the vertical rotation motor 240. The vertical rotation motor 240 may include a rotating unit 241 connected to the central axis and forming a rotating plate perpendicular to the central axis, and the second end 253 of the rotating power transmission rod 250 is such a rotating unit 241 When the rotating part 241 rotates while being rotatably coupled to the end of the rotating plate, it can perform circumferential movement at the edge of the rotating plate.

The injection port 210 may inject the fluid to the outside while being in fluid communication with the vertical rotation pipe 200. The injection port 210 may include a coupling part 211 and an injection part 212, and the coupling part 211 may be screwed with the second pipe connection part 260 disposed between the vertical rotation pipe 200. have. In addition, the injection portion 212 may have a cross-sectional area of a portion facing the outside and formed to be narrower than a cross-sectional area of a portion facing the coupling portion 211, thereby increasing injection pressure.

The first end 252 that is rotationally coupled with the protrusion of the vertical rotation pipe 200 may rotate about the same rotation axis as the rotation axis of the vertical rotation pipe 200. In addition, the second stage 253 may rotate about the same rotation axis as the rotation axis of the vertical rotation motor 240. The rotation shaft of the vertical rotation pipe 200 and the rotation shaft of the vertical rotation motor 240 may be separated from each other.

As the rotation radius of the first end 252 is formed larger than the rotation radius of the second end 253, the rotation angle of the vertical rotation pipe 200 may be limited to a predetermined angle. For example, when the second end 253 is at the position of A1, the first end 252 may be at the position of B1 according to the movement of the rotational power transmission rod 250, and the first end 252 When it is in the position of B1, the injection port 210 may be in the position of C1. And, when the second end 253 moves in a direction away from the vertical rotation pipe 200 and becomes the position A3, the first end 252 moves to the position B3 while moving backward, and the injection port 210 is C3 You can go downwards while moving to. And, when the second end 253 moves in a direction closer to the vertical rotation pipe 200 and becomes the position of A2, the first end 252 moves to the position of B2 while moving forward, and the injection port 210 is You can go upwards while moving to C2.

Since the rotation radius of the second stage 253 is formed smaller than the rotation radius of the first stage 252, even if the second stage 253 rotates one turn, the first stage 252 does not rotate one revolution. It can only be rotated by an angle. This structure can prevent a problem in which the injection port 210 collides with the vehicle frame or injects fluid in an unintended direction due to a malfunction or the like.
