Description
Technical Field
[0001] The utility model relates to the technical field of special sanitation vehicles, and particularly relates to a water spraying sanitation vehicle. Background Art
[0002] A water spraying sanitation vehicle is a special operation vehicle with a water spraying device, such as a nozzle or a spray gun, and can clean the road surface by spraying water through the water spraying device; among the existing water spraying sanitation vehicles, there are both large water spraying sanitation vehicles with large automatic water spraying devices, such as water spraying sanitation vehicles modified from tanker trucks; and there are also water spraying sanitation vehicles only equipped with small water spraying devices, and when spraying water, the staff need to hold the water spraying device to control the water spraying position, such as pickup water spraying sanitation vehicles or three-wheel water spraying sanitation vehicles.
[0003] For small water spraying sanitation vehicles, since the staff need to hold the water spraying device, their working mode is often that the staff first drive the water spraying sanitation vehicle to a predetermined position, then get off the vehicle to take out the water spraying device and carry out cleaning, and then get on the vehicle and move to the next cleaning position after the cleaning is completed, and so on in a cycle; it can be seen that for small water spraying sanitation vehicles, they need to constantly repeat the steps of parking, getting off the vehicle, getting on the vehicle and driving when working, with low cleaning speed, low cleaning efficiency, and potential safety hazards. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the existing small water spraying sanitation vehicles that require the staff to constantly park and get on and off the vehicle, resulting in low cleaning speed, low cleaning efficiency, and potential safety hazards, and to provide a water spraying sanitation vehicle.
[0005] In a first aspect, the utility model provides a water spraying sanitation vehicle, which includes a vehicle body and a water spraying device, and further includes:
[0006] A swing arm, one end of the swing arm is connected to the vehicle body through a first swing joint; the swing arm has a first position and a second position relative to the vehicle body; when the swing arm swings to the first position, the swing arm fits against the vehicle body; when the swing arm swings to the second position, the swing arm extends towards the side of the vehicle body;
[0007] A connecting part, the connecting part is arranged at the end of the swing arm far from the vehicle body, and the water spraying device is connected to the connecting part.
[0008] The vehicle body includes but is not limited to a minibus, a pickup truck, a tricycle, a truck; the water spraying device includes but is not limited to a water gun, a nozzle; the specific structural form of the connecting part matches the water spraying device, and includes but is not limited to a clamping structure, a pin structure, a bundling structure.
[0009] The setting direction of the first swing joint includes but is not limited to the axis being set in the plumb direction, enabling the swing arm to swing in the horizontal plane, or the axis being set in the horizontal direction, enabling the swing arm to swing in the vertical plane; the connection position of the first swing joint includes but is not limited to the left and right sides, the front, and the back of the vehicle body.
[0010] In the water spraying sanitation vehicle of this solution, a swingable swing arm is added to the vehicle body. When it is necessary to spray water to clean the ground, the water spraying device is connected to the connecting part on the swing arm, and the swing arm is swung to the second position, then the water spraying device can extend towards the side of the vehicle body together with the swing arm. At this time, start the water spraying device and drive the vehicle, and it can clean the area to be cleaned on the side of the vehicle body along the driving road. It can be seen that when cleaning the area to be cleaned in this solution, the staff only needs to drive attentively, without having to hold the water spraying device, stop frequently, and get on and off the vehicle. Therefore, the cleaning speed and cleaning efficiency can be greatly improved, and the safety hazards caused by frequent stopping and getting on and off the vehicle can be reduced.
[0011] When the cleaning work is over, the swing arm can be swung to the second position to make the swing arm fit the vehicle body, reducing the overall external dimension of this solution, thereby reducing the overall floor area of this solution, making this solution easier to park, and avoiding the swing arm from hindering the movement of the vehicle body.
[0012] Preferably, the axis of the first swing joint is set in the horizontal direction, and the height where the second position is located is lower than the height where the first position is located.
[0013] In this solution, that is, the swing arm swings in the vertical plane, and it needs to swing downward to reach the second position and swing upward to reach the first position. Thus, when it is necessary to spray water to clean the ground and the swing arm is in the second position, the swing arm can be automatically stabilized in the second position under the action of gravity, so that the corresponding locking mechanism can be omitted, reducing the manufacturing cost of this solution.
[0014] Preferably, a second swing joint is further provided between the swing arm and the vehicle body, and the axis of the second swing joint is set in the plumb direction.
[0015] Between the swing arm and the vehicle body, for example, between the swing arm and the first swing joint or between the first swing joint and the vehicle body.
[0016] This solution adds a degree of freedom of movement with the axis in the plumb direction to the swing arm. That is, in addition to being able to swing in the vertical plane and thus switch between the first position and the second position, the swing arm can also swing in the horizontal plane. On the one hand, it can make this solution more freely adjust the orientation of the water spraying device. On the other hand, when the swing arm collides with other structures, such as trees and street lamps, the swing arm can yield to reduce the damage caused by the collision.
[0017] Preferably, it further includes a cable, one end of the cable is connected to the swing arm, and the other end of the cable is connected to the vehicle body.
[0018] The specific forms of the cable include but are not limited to nylon ropes, steel wire ropes, iron chains, and chains.
[0019] This solution enables the staff to adjust the swing angle of the swing arm or retract the swing arm through the cable without getting off the vehicle.
[0020] Preferably, the swing arm includes at least two segments, and adjacent segments are slidably connected. The segment closest to the vehicle body is connected to the vehicle body through a first swing joint; the relative sliding of the segments can adjust the length of the swing arm.
[0021] This solution makes the length of the swing arm adjustable, so that the distance that the connecting part connected to the swing arm and the corresponding water spraying device extend relative to the vehicle body is also adjustable, and thus the cleaning range of the water spraying device can be changed.
[0022] Preferably, a locking structure is also provided between adjacent swing arms, and the locking structure is used to lock or unlock the relative sliding of adjacent segments.
[0023] The locking structure includes but is not limited to plug-in type, friction type, and magnetic attraction type.
[0024] This solution adds a locking structure to the swing arm to lock the length of the swing arm, which can prevent unexpected changes in the length of the swing arm, thereby avoiding situations where the cleaning area changes or a rubbing accident occurs.
[0025] Preferably, the number of connecting parts is greater than one, and the connecting parts are distributed at intervals along the length direction of the swing arm.
[0026] This solution can connect multiple water spraying devices to one swing arm at the same time, thereby increasing the cleaning range.
[0027] Preferably, the water spraying device is detachably connected to the connecting part.
[0028] The specific ways of detachable connection include but are not limited to threaded connection, mortise and tenon connection, and snap connection.
[0029] This solution enables the staff to remove and hold the water spraying device to clean the sanitary dead corners separately when cleaning some sanitary dead corners.
[0030] Preferably, the number of swing arms is greater than one, and swing arms are connected to both the left and right sides of the vehicle body.
[0031] This solution can facilitate the cleaning of the areas on both the left and right sides of the vehicle body at the same time.
[0032] Preferably, a limit baffle is also connected to the vehicle body. The limit baffle is arranged horizontally and is located below the first swing joint.
[0033] This solution can prevent the swing arm from swinging down too much and touching the ground, which may cause damage to the swing arm or hinder the movement of the vehicle body by the swing arm.
[0034] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0035] The present utility model provides a water spraying sanitation vehicle. By adding a swingable swing arm to the vehicle body, when it is necessary to spray water to clean the ground, the water spraying device is connected to the connecting part on the swing arm, and the swing arm is swung to the second position, then the water spraying device can extend towards the side of the vehicle body together with the swing arm. At this time, start the water spraying device and drive the vehicle, and the area to be cleaned on the side of the vehicle body can be cleaned along the driving road. It can be seen that when cleaning the area to be cleaned, the staff only needs to drive attentively, without holding the water spraying device, frequently stopping and getting on and off the vehicle. Therefore, the cleaning speed and efficiency can be greatly improved, and the potential safety hazards caused by frequent stopping and getting on and off the vehicle can be reduced.
[0036] When the cleaning work is completed, the swing arm can be swung to the second position to make the swing arm fit the vehicle body, reducing the overall external dimension of this solution, thereby reducing the overall floor area of this solution, making this solution easier to park, and avoiding the swing arm from hindering the movement of the vehicle body.
