The water spray rack should have an obstacle avoidance function during the flushing process to avoid collision with the isolation belt. Existing water spray racks mostly use passive obstacle avoidance mechanisms such as springs. When encountering an obstacle, the spring is compressed to form an obstacle avoidance mechanism. However, this collision-type obstacle avoidance method will damage the water spray rod on the side of the water spray rack as the use time increases, affecting normal use.

[0003] In addition, the existing nozzle spraying frame is fixedly installed, and the water it sprays is a single water line, which can only wash the road surface in a single water line, and the cleaning effect on the hardened road surface is not ideal. In addition, the nozzles fixed on the spraying frame are arranged in a straight row, and the nozzles are arranged in large numbers, resulting in a large water consumption. Utility Model Content

[0004] The utility model aims to provide a water spraying frame and a sanitation vehicle, which can be suitable for the inclination of hardened road surface.

[0016] 1. The water spraying frame drives the water spraying rod to rotate by adding a first driving member to realize rotary spraying, and the water spraying rod is pitched by a second driving member, thereby realizing the adjustment of different water pressures for washing the ground. For hardened roads, the ground clearance of the fan-shaped nozzle can be reduced, the water pressure that impacts the ground can be increased, and the cleanliness of road washing can be improved;

DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0026] like Figure 1 As shown, a water spray frame provided in this embodiment includes a water spray rod 1, a distance sensor 2, a fourth driving member 3, a second driving member 4, a first driving member 5, a second fixed frame 6, a third driving member 7, a slide rail 8, a slider 9, a first fixed frame 10, a fourth fixed frame 11, a fifth driving member 12, a hinge 13, a fan-shaped nozzle 14 and a third fixed frame 15.

[0027] The water spray rod 1 is U-shaped and has two ends, on which fan-shaped nozzles 14 are installed. The interior of the water spray rod 1 is a water flow pipeline. The middle of the water spray rod 1 is used to connect with the output shaft of the first driving member 5.

[0028] The first fixing frame 10 is connected to the second fixing frame 6 (such as Figure 2 A second driving member 4 is provided between the first fixing frame 10 and the second fixing frame 6 for driving the second fixing frame 6 to pitch and swing along the hinge 13. The second driving member 4 is an electric push rod, and an oil cylinder or an air cylinder can also be used. A plurality of the second driving members 4 are evenly distributed in the X direction.

[0029] The first driving member 5 is provided with a plurality of the second fixing frame 6, and the output shaft of each of the first driving members 5 passes through the second fixing frame 6 and is connected to one of the water spraying rods 1. The first driving member 5 is installed in a direction perpendicular to the second fixing frame 6, so that the output shaft of the first driving member 5 passes through the second fixing frame 6 and is connected to the water spraying rod 1. The first driving member 5 is a motor, which is used to drive the water spraying rod 1 to rotate.

[0030] like Figure 1 , Figure 3 As shown, the first driving member 5 provides a driving force for the water spraying rod 1 to rotate, and the water lines of the adjacent rotating fan-shaped nozzles 14 are elliptical, and there is a certain overlap when hitting the ground. The elliptical mark formed by the two fan-shaped nozzles 14 on one water spraying rod 1 can cover a wider cleaning width, so that the cleaning quality can be guaranteed without increasing the number of nozzles, and the purpose of water saving can be achieved. At the same time, the number of cleaning times at the relative position can be increased by adjusting the rotation speed of the first driving member 5.

[0031] In addition, the pitch angle between the second fixing frame 6 and the ground is adjusted by extending and retracting the second driving member 4, thereby regulating the height of the fan-shaped nozzle 14 from the ground and the angle between the waterline and the ground, which has a stronger cleaning ability for hardened roads.

[0032] like Figure 1 As shown, the end of the first fixing frame 10 away from the second fixing frame 6 is connected to the third fixing frame 15, and the third driving member 7 is vertically installed on the third fixing frame 15 (as shown in FIG. Figure 2 The third fixing frame 15 is provided with a third driving member 7 for driving the first fixing frame 10 to rotate.

[0033] A distance sensor 2 is disposed on the end side of the first fixing frame 10 , and the distance sensor 2 is electrically connected to the third driving member 7 .

[0034] The first fixing frame 10 is provided with a fourth driving member 3 for driving the distance sensor 2 to rotate, and the rotation axis of the fourth driving member 3 is consistent with the rotation axis of the third driving member 7 (eg Figure 2 As shown, the rotation axis is vertically arranged), the fourth driving member 3 has the same rotation stroke as the third driving member 7, and the rotation direction is opposite. The third driving member 7 is a motor, and the fourth driving member 3 can directly purchase a return mechanism. The function of the return mechanism is that when the third driving member 7 drives the first fixing frame 10 and the second fixing frame 6 to rotate, the distance sensor 2 always keeps its sensing surface parallel to the isolation belt plane through the fourth driving member 3. The fourth driving member 3 can also be selected as a motor, and the mapping relationship between the rotation stroke and the rotation direction with the third driving member 7 can be set in the program.

[0035] The third fixing frame 15 is connected to a slider 9 via bolts on one side away from the first fixing frame 10. The slider 9 is slidably connected to the slide rail 8. The slide rail 8 is installed at the front end of the body of the sanitation vehicle via the fourth fixing frame 11. A fifth driving member 12 is connected between the slide rail 8 and the third fixing frame 15. The fifth driving member 12 is an electric push rod. The telescopic action of the fifth driving member 12 is used to adjust the positions of the first fixing frame 10 and the second fixing frame 6 and the water spraying rod 1 thereon in the X direction via the third fixing frame 15.

[0036] For example, when the water spraying rack is in operation, the distance sensor 2 is activated to sense the distance to the roadside edge in real time. If the distance is insufficient or too far, a signal is sent to the processor, and the processor sends a control instruction to start the fifth driving member 12 to move, so that the right side of the water spraying rack (the right side of the driver) is moved. Figure 1 The distance from the side where the distance sensor 2 is installed to the roadside isolation belt is adjusted to an appropriate distance to ensure effective flushing of the road surface and achieve active obstacle avoidance and edge cleaning.

[0037] The utility model also provides a sanitation vehicle, comprising a vehicle body and the above-mentioned water spraying frame arranged at the front end of the vehicle body. The water spraying rod 1 is connected with the water tank of the vehicle body to realize high-pressure spraying. And the front end of the vehicle body is designed with a lifting and deflecting mechanism, which is connected to the water spraying frame.

[0038] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
