Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figures 1-4 As shown, a blower system with automatic obstacle avoidance function is used for road blowing when installed on a vehicle. The system includes a blower 1 installed on the vehicle and a deformable duct assembly 2 connected to the blower 1. The air outlet end of the duct assembly 2 is close to the road surface and is equipped with a driving wheel 24. The system also includes a guide assembly 3, which is used to guide the driving wheel 24 and the air outlet end of the duct assembly 2 to rise and fall when the driving wheel 24 encounters road obstacles.

[0026] Specifically, the duct assembly 2 includes a first duct 21, a flexible duct 22, and a second duct 23. The first duct 21 is connected to the fan 1, and the air outlet is located on the side of the second duct 23.

[0027] The two ends of the flexible air duct 22 are connected to the first air duct 21 and the second air duct 23. The connection is secured with clamps 26. The flexible air duct 22 will deform as the second air duct 23 is raised and lowered during use. Therefore, clamps 26 are used to secure the connection between the flexible air duct 22 and the air ducts at both ends.

[0028] The blowing system also includes a lifting assembly 4 for lifting the second air duct 23. The lifting assembly 4 includes a telescopic drive part 41 for pulling up the second air duct 23. The drive end of the telescopic drive part 41 is provided with a non-rigid traction member 42 for connecting with the second air duct 23. The telescopic drive part 41 can be a drive component such as an electric push rod, a cylinder, or a hydraulic cylinder. The traction member 42 is set as a hanging chain or a traction rope. Changing the length of the traction member 42 can adjust the upward lifting limit of the air duct 23, so that the second air duct 23 can move upward to avoid obstacles.

[0029] By setting the duct assembly 2 into three sections, the middle section uses a flexible duct 22, and a non-rigid traction component 42 is set to lift the lowermost second duct 23. When lifted, it is used to store the second duct 23. When lowered, the second duct 23 can sway up and down along its lifting trajectory due to the loose connection of the traction component 42. With the help of the traveling wheels 24 set on the second duct 23, it has an automatic obstacle avoidance function.

[0030] The walking wheels 24 are raised and lowered on the second air duct 23, and the wheel covers of the walking wheels 24 are provided with guide plates 25. When an obstacle appears, the obstacle lifts the second air duct 23 upward along the curved surface of the guide plate 25, thereby achieving automatic obstacle avoidance.

[0031] The guide assembly 3 comprises a fixed frame 31 fixedly connected with the vehicle, and a first connecting rod and a second connecting rod 36 are arranged between the fixed frame 31 and the second air pipe 23. The fixed frame 31 is connected with the vehicle through at least two fixing bolts 32. The guide assembly 3 is used for limiting the upward trajectory of the second air pipe 23. When the second air pipe 23 encounters an obstacle, the first connecting rod and the second connecting rod 36 make the second air pipe 23 have a trajectory of moving obliquely upward in the opposite direction. That is, even if an obstacle higher than the walking wheel 24 is encountered, after the second air pipe 23 contacts the obstacle, the second air pipe 23 will automatically rise obliquely upward in the opposite direction through the first connecting rod and the second connecting rod 36. As shown in Figure 3 When an obstacle higher than the walking wheel 24 appears on the right side of the second air pipe 23, the second air pipe 23 moves to the left side compared with the vehicle (that is, the fixed frame 31). Under the action of the first connecting rod and the second connecting rod 36, the second air pipe 23 has a tendency to automatically rise. Then, after the height is raised, the obstacle is crossed through the walking wheel 24.

[0032] A profile plate 37 is rotatably arranged on the first connecting rod. The surface of the second air pipe 23 is provided with a buffer pad 38. The profile plate 37 is used to press the buffer pad 38 when the second air pipe 23 is pulled up, so as to limit the upward shaking of the second air pipe 23. Through the arrangement of the buffer pad 38 and the profile plate 37, the upward and downward shaking of the second air pipe 23 is prevented after the second air pipe 23 is pulled up. As shown in Figures 2-3 Since the shaft part connected with the fixed frame 31 of the first connecting rod and the second connecting rod 36 has a constant height, when the connecting rod rotates upward, the profile plate 37 located in the middle part of the first connecting rod moves at a lower speed than the second air pipe 23. That is, the stroke amplitude of the second air pipe 23 when rising is greater than that of the profile plate 37. Therefore, when rising to a certain extent, the buffer pad 38 on the second air pipe 23 contacts the profile plate 37, and has a tendency to be pressed. The second air pipe 23 is subjected to upward pulling force of the traction member 42 and downward pressure of the profile plate 37 at the same time, so as to prevent shaking. In cooperation with the connecting rods on both sides, the second air pipe 23 is completely fixed.

[0033] The profile plate 37 is rotatably connected with the first connecting rod through a rotating shaft. The fixed position of the rotating shaft on the first connecting rod has an adjusting space. The position of the profile plate 37 can be adjusted. Specifically, the position of the profile plate 37 can be adjusted by changing the position of the rotating shaft. This setting can change the initial distance between the profile plate 37 and the buffer pad 38, so as to adjust the height when they contact, and further change the pressing force when the second air pipe 23 is lifted. The adjusting mode of the rotating shaft and the first connecting rod can adopt the prior art. Only the position needs to be changed and fixed. Therefore, no specific description is given here.

[0034] The embodiment is characterized in that: the fan 1, the telescopic driving part 41 and the fixed frame 31 are installed on the vehicle, when the vehicle is moving forward, the second air pipe 23 is lowered by the telescopic driving part 41, the second air pipe 23 falls due to the gravity or an additional spring, wind power is generated by the fan 1, and the wind is blown out by the second air pipe 23, the walking wheel 24 rolls on the ground, when an obstacle is encountered, the second air pipe 23 is lifted by the walking wheel 24 or the guide plate 25, or the second air pipe 23 is directly lifted upwards and backwards, so as to achieve the purpose of automatic obstacle avoidance, when the wind is not needed to be blown, the telescopic driving part 41 pulls the traction part 42, the second air pipe 23 is lifted, and then the second air pipe 23 is fixed by the contact of the mold plate 37 and the buffer pad 38.

[0035] Embodiment 2

[0036] Different from the embodiment 1, the first connecting rod of the embodiment is a telescopic rod with adjustable length, the first connecting rod comprises a first articulated rod 33 connected with the second air pipe 23 and a second articulated rod 34 connected with the fixed frame 31, the first articulated rod 33 and the second articulated rod 34 are connected with each other in the axial direction and are telescopic, and a bolt 35 is arranged on one of the articulated rods, which is used for fixing the other articulated rod after telescoping, the first connecting rod with adjustable length is arranged, so as to adjust the angle between the outlet of the second air pipe and the ground.

[0037] The above-mentioned embodiments only express several embodiments of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent range. It should be pointed out that, for ordinary skilled person in the art, without departing from the concept of the utility model, a number of deformations and improvements can be made, which belong to the protection range of the utility model.
