[0002] Sprinkler trucks are also called spray trucks, multi-function sprinkler trucks, landscaping sprinkler trucks, water tankers, water trucks, etc. Sprinkler trucks are used in urban roads, large factories, military units, gardens and other units to clean roads, prevent dust, water, spray pesticides, etc., in order to beautify the environment.

[0003] During the watering process, the sprinkler truck needs to flush the road. The water spraying direction of the nozzle installed on the sprinkler truck in the existing technology is generally perpendicular to the moving direction of the vehicle body, that is, perpendicular to the extension direction of the road. The nozzle can only spray water at a fixed angle and direction directly in front of it, so that the sprinkled water flow can only flush a fixed road surface.

[0004] However, sometimes areas diagonally in front of or behind the road (i.e., blind spots) also need to be flushed. Conventional sprinklers can only spray the area directly in front of them. Conventional sprinklers have the disadvantages of a small spraying range, inadequate flushing of blind spots, and the need for repeated flushing. In addition, existing sprinkler systems require manual adjustment of the sprinkler head angle, which is very inconvenient to use. Utility Model Content

[0044] Example 1

[0045] See also Figure 1-Figure 5 Now, an electric rotary sprinkler device provided by an embodiment of the utility model is described.

[0046] In one embodiment of the present invention, an electric rotary sprinkler device of the embodiment of the present invention includes a first connecting pipe 1, a second connecting pipe 2, a nozzle 3 and a drive motor 4, one end of the second connecting pipe 2 is rotatably connected to the first connecting pipe 1, and the second connecting pipe 2 is a curved pipe; the nozzle 3 is connected to the other end of the second connecting pipe 2; the rotating shaft of the drive motor 4 is connected to the outer shell of the second connecting pipe 2.

[0047] When in use, an electric rotary sprinkler device according to an embodiment of the present invention is divided into conventional sprinkler operation and special sprinkler operation. Conventional sprinkler operation is when the nozzle 3 sprinkles water at a fixed angle perpendicular to the extension direction of the road surface (or the direction of travel of the vehicle body). When the area obliquely in front of or behind the road surface (blind spot) needs to be sprayed and cannot be sprayed under conventional sprinkler operation, a special sprinkler operation is required. At this time, the drive motor 4 is started. By starting the drive motor 4, the rotation shaft of the drive motor 4 rotates. Since the rotation shaft of the drive motor 4 is connected to the outer shell of the second connecting tube 2, it will drive the second connecting tube 2 to rotate horizontally relative to the first connecting tube 1, thereby driving the nozzle 3 to rotate within a certain range, thereby achieving the adjustment of the spraying angle of the nozzle 3.

[0048] The water sprinkling direction of a conventional sprinkler is perpendicular to the extension direction of the road surface, while the electric rotary sprinkler device of this embodiment can adjust the water sprinkling angle of the sprinkler head 3 by driving the motor 4. The water sprinkling direction of the sprinkler head 3 can be adjusted to 0-180°, where 0° and 180° are parallel to the extension direction of the road surface. This can expand the spraying range of the sprinkler head 3, allowing the sprinkler head 3 to spray and flush blind areas, making the flushing more comprehensive and thorough. The sprinkler head 3 is driven to rotate by the driving motor 4, and there is no need to manually adjust the water sprinkling angle of the sprinkler head 3, making it more convenient to use.

[0049] In this embodiment, the second connecting pipe 2 is a curved pipe, and its bending angle (i.e., the angle between the elbow and the vertical direction) is preferably greater than 45° and less than 80°, and more preferably 70-75°. For example, the second connecting pipe 2 can be designed as a 73° elbow so that the angle range formed between it and the ground is appropriate, which facilitates comprehensive flushing of the ground and has a better flushing effect.

[0050] In this embodiment, the shape of the nozzle 3 is not particularly limited. This embodiment is illustrated by taking a duckbill nozzle as an example. The water outlet of the duckbill nozzle is a linear water spray seam. The thickness of the inner cavity of the nozzle 3 gradually decreases from the end close to the second connecting pipe 2 to the end close to the water spray seam, and the width of the inner cavity of the nozzle 3 gradually increases from the end close to the second connecting pipe 2 to the end close to the water spray seam.

[0051] In this embodiment, the drive motor 4 is a DC rotary motor, which provides power for the second connecting pipe 2 to rotate in the horizontal direction. The rotation angle can be adjusted according to the actual use scenario. Generally, the drive motor 4 drives the second bend pipe 2 to rotate in the horizontal direction at a angle of 0-180°. Specifically, the drive motor 4 drives the second bend pipe 2 to rotate in the horizontal direction first in the forward direction of 0-180°, and then in the reverse direction of 0-180°, and so on. The speed of the drive motor 4 can be controlled to be relatively low, generally 5-10r / min. This forward and reverse operation of the drive motor 4 can be achieved by electrically connecting the drive motor 4 to a conventional motor forward and reverse switching control device; this forward and reverse operation of the drive motor 4 can also be achieved by mechanical limit plus manual auxiliary operation, which is not limited in this embodiment.

[0052] In this embodiment, the first connecting pipe 1 and the second connecting pipe 2 are both circular pipes and are made of stainless steel. Compared with aluminum alloy, stainless steel has higher hardness, wear resistance, pressure resistance and corrosion resistance.

[0053] Furthermore, the electric rotary sprinkler device of this embodiment further includes a fixing bracket 5, and the drive motor 4 is fixedly connected to the fixing bracket 5. The fixing bracket 5 is provided to provide a fixed installation position for the drive motor 4.

[0054] Furthermore, the first connecting pipe 1 of this embodiment is a curved pipe. A connecting flange 6 is provided at one end of the first connecting pipe 1. A connecting plate 7 is connected to the connecting flange 6. One end of the fixed bracket 5 is connected to the connecting plate 7. The connecting plate 7 connects the fixed bracket 5 and the connecting flange 6 into one piece, improving the integrity of the device. The first connecting pipe 1 can be a 90° elbow, connected to the water supply pipe via the connecting flange 6 at the end. The connecting plate 7 and the connecting flange 6 can be integrally formed, or the connecting plate 7 can be welded or threaded onto a conventional circular connecting flange 6.

[0055] Furthermore, the fixing bracket 5 and the connecting plate 7 of this embodiment are fixedly connected by connecting screws 8 and nuts, which facilitates installation and disassembly.

[0056] Furthermore, the fixing bracket 5 and the connecting plate 7 of this embodiment are fixedly connected by a limiting screw 9 and a nut, and the length of the limiting screw 9 is greater than that of the connecting screw 8. Figure 1 、 Figure 2 、 Figure 5As shown, the connecting plate 7 of this embodiment is provided with four threaded holes, the two lower threaded holes are used to install the connecting screws 8 to connect the fixing bracket 5 and the connecting plate 7 into one, and the two upper left-right symmetrical threaded holes are used to install the limiting screws 9. When in use, the rotation angle of the second connecting tube 2 can be limited by adjusting the protruding length of the limiting screw 9 toward the side of the second connecting tube 2. When the end of the limiting screw 9 abuts against the outer shell of the second connecting tube 2, it will prevent the second connecting tube 2 from continuing to rotate, thereby playing a limiting role. In this embodiment, by providing a limit screw 9, the forward and reverse operation of the drive motor 4 can be achieved by mechanical limiting and manual auxiliary operation. Specifically, when the end of the limit screw 9 on one side abuts against the outer shell of the second connecting pipe 2, the operator observes that the spraying direction of the sprinkler head 3 will no longer change. At this time, the operator can press the reverse control switch of the drive motor 4 to make the drive motor 4 rotate in the opposite direction. When the outer shell of the second connecting pipe 2 abuts against the limit screw 9 on the other side again, the operator presses the reverse control switch of the drive motor 4 again until the spraying operation of the blind spot is completed and then turns off the drive motor 4, so that the sprinkler head 3 returns to the normal watering working state.

[0057] Furthermore, in this embodiment, the fixing bracket 5 is provided with a through-hole, through which the rotating shaft of the drive motor 4 passes and is connected to the housing of the second connecting tube 2. Furthermore, a first bearing 10 is fixedly connected within the through-hole, and the rotating shaft of the drive motor 4 is rotatably connected within the first bearing 10. The provision of the first bearing 10 improves the rotational stability of the rotating shaft of the drive motor 4.

[0058] Furthermore, the electric rotary sprinkler device of this embodiment further includes a connecting boss 11 connected to the fixing bracket 5. The connecting boss 11 has a mounting hole at its center, into which the drive motor 4 is fixedly connected. The connecting boss 11 can be fixedly connected to the fixing bracket 5 by screws.

[0059] Furthermore, the fixing bracket 5 of this embodiment comprises a horizontal plate 501 and a vertical plate 502 connected in an L-shape. The vertical plate 502 is connected to the connecting plate 7. The fixing bracket 5 can be made of a rectangular plate bent 90°. In this case, the connecting boss 11 is fixedly connected to the horizontal plate 501, and the first bearing 10 is fixedly mounted in a through-hole provided in the horizontal plate 501.

[0060] Furthermore, the electric rotary sprinkler device of this embodiment also includes a reinforcing rib 12, the two ends of which are respectively connected to the connecting plate 7 and the first connecting pipe 1, that is, the reinforcing rib 12 is horizontally connected between the connecting plate 7 and the vertical section of the first connecting pipe 1. By providing the reinforcing rib 12, the overall strength of the device connected by the first connecting pipe 1, the second connecting pipe 2, the fixing bracket 5 and the connecting flange 6 can be improved.

[0061] Furthermore, in this embodiment, a seal 13 is provided at the connection between the second connecting pipe 2 and the first connecting pipe 1. The seal 13 is generally a sealing ring. By providing the seal 13, water leakage at the connection between the first connecting pipe 1 and the second connecting pipe 2 is prevented.

[0062] Furthermore, in this embodiment, a second bearing 14 is provided at the connection between the second connecting pipe 2 and the first connecting pipe 1. By providing the second bearing 14, the stability of the second connecting pipe 2 in rotating relative to the first connecting pipe 1 can be improved. The second bearing 14, the first bearing 10 and the rotating shaft of the drive motor 4 are coaxially arranged, which can make the rotating shaft of the drive motor 4 rotate flexibly and not eccentric. Specifically, Figure 1 、 Figure 3 As shown, a circular step-shaped groove is provided at the upper end of the first connecting tube 1, and the second bearing 14 is arranged in the circular step-shaped groove, and the outer ring of the second bearing 14 is fixedly connected to the inner wall of the circular step-shaped groove of the first connecting tube 1, and the inner ring of the second bearing 14 is fixedly connected to the outer wall of the second connecting tube 2.

[0063] Furthermore, a spline 15 is provided on the rotating shaft of the driving motor 4 of this embodiment, and the rotating shaft of the driving motor 4 is connected to the outer shell of the second connecting pipe 2 through the spline 15, that is, the rotating shaft of the driving motor 4 is a spline shaft.

[0064] Furthermore, the nozzle 3 of this embodiment is threadedly connected to the other end of the second connecting pipe 2. The nozzle 3 and the second connecting pipe 2 are threadedly connected, which facilitates the installation or disassembly of the nozzle 3 and the quick replacement of different types of nozzles 3.

[0065] Furthermore, the electric rotary sprinkler system of this embodiment includes a control device (not shown) electrically connected to the drive motor 4. The control device is used to control the start and stop of the drive motor 4, including forward and reverse rotation. The control device allows for convenient remote control of the drive motor 4. For example, in actual use, the control device can be installed in the cab of a sprinkler truck, and the driver can control the operating state of the electric rotary sprinkler system by manipulating the control device.

[0066] The electric rotary sprinkler device of this embodiment is compact, lightweight, and easy to install. The ground clearance of the water outlet is adjustable, eliminating the risk of damage to the sprinkler head 3 due to low ground clearance. The device utilizes a direct drive motor 4, significantly reducing its size compared to conventional worm gear transmissions. The device also boasts a compact structure, ease of installation, and convenient maintenance. A control device allows for electronic or wireless remote control operation. A limit screw 9 allows the rotation angle of the second connecting pipe 2 to be adjusted within a range of 0-180°.

[0069] Specifically, the electric rotary sprinkler of embodiment 1 can be symmetrically installed on the left and right sides of the vehicle body. In this way, when the sprinkler truck is working, it can spray water to clean the road surface on both sides of the vehicle body synchronously.

[0070] The sprinkler truck of this embodiment can adjust the angle of the nozzle 3 spraying water, expand the spraying range of the nozzle 3, and flush more comprehensively and thoroughly; and the nozzle 3 is driven to rotate by the drive motor 4, and there is no need to manually adjust the water spraying angle of the nozzle 3, which is more convenient to use.
