Description

Technical Field

[0001] The utility model belongs to the technical field of engineering vehicles, and particularly relates to a splash-proof cover plate assembly and a sprinkler truck. Background Art

[0002] The sprinkler truck is suitable for various road flushing, tree, green belt, lawn greening, road and factory and mine enterprise construction, and high-rise building flushing. It has functions such as water sprinkling, dust suppression, high and low position spraying, pesticide spraying, guardrail flushing, etc., and also has functions such as water transportation, drainage, and emergency fire fighting.

[0003] The water flow will spread immediately after being sprayed out of the water pipe. There are mainly two reasons. Firstly, the water flow injection will drive the air flow nearby, so there will be a pressure difference on the surface of the water flow, causing the water flow to spread; secondly, the water flow bears gravity and air resistance opposite to the water flow during air injection. This resistance is positively correlated with the flow velocity. The faster the flow velocity, the greater the resistance. For the water flow microelement, the extrusion causes the movement direction to deviate.

[0004] The water flow sprayed from the bottom of the sprinkler truck flushes the road surface. Part of the water flow spreads upward and flies, and another part is splashed when flushing the road surface; since the water used for flushing the road surface does not have the purpose of dust suppression in the air, the water flow on this road is mixed with impurities on the ground to form sewage after being sprayed out. The upward sewage will not only affect passers-by, but also cause the sewage to splash everywhere. Especially when operating on a relatively narrow road with a large number of pedestrians, the impact is particularly obvious. Content of the Utility Model

[0005] In order to solve the problem that the sewage formed during the flushing of the road surface has a greater impact on pedestrians during the splashing process, the utility model provides a splash-proof cover plate assembly and a sprinkler truck.

[0006] The utility model is realized by the following technical solutions:

[0007] A splash-proof cover plate assembly includes a frame. A driving rotating shaft is rotatably arranged on the frame. One end of the driving rotating shaft is connected with a driving motor installed on the frame, and a gear is arranged on the driving rotating shaft;

[0008] A supporting wheel is rotatably arranged on the frame below the driving rotating shaft;

[0009] A cover plate body is arranged between the supporting wheel and the gear. Tooth patterns meshing with the gear are arranged on the top surface of the cover plate body, and its bottom surface is in rolling contact with the supporting wheel.

[0010] The cover body is driven by the meshing of the gears and the teeth, and the supporting wheels support the cover body at the bottom, thereby guiding the cover body to extend or retract outward. By extending the cover body outward, the water source that directly flies upward and splashes on the road surface can be blocked, the height of the water source and the splashing range can be reduced, and the impact on passers-by during the watering operation can be reduced.

[0011] A further improvement of the utility model is that the axis line of the driving shaft is arranged on one side of the vertical plane where the axis line of the supporting wheel is located.

[0012] A further improvement of the utility model is that the cover plate body as a whole is in an upwardly raised arc-shaped structure.

[0013] A further improvement of the utility model is that two supporting wheels are provided, and the two supporting wheels and the gear are distributed in an isosceles triangle.

[0014] A further improvement of the present invention is that a groove is provided on the top surface of the cover body, the width of the groove is not less than the thickness of the gear, and the tooth pattern is arranged in the groove.

[0015] A further improvement of the present invention is that the tooth tips of the tooth patterns do not exceed the top surface of the cover plate body.

[0016] A further improvement of the utility model is that the frame as a whole is in a 冂-shaped structure.

[0017] A water sprinkler comprises a water sprinkler body and an anti-splash cover assembly; the frame is arranged above the water spraying port of the water sprinkler body and is installed on the bottom surface of the frame of the water sprinkler body.

[0018] It can be seen from the above technical scheme that the beneficial effects of the utility model are: the cover body is driven by the meshing of the gears and the teeth, and the supporting wheels support the cover body at the bottom, thereby guiding the cover body to extend or retract outward; by extending the cover body outward, the water source that directly flies upward and splashes on the road surface can be blocked, the height of the water source and the splashing range can be reduced, and the impact on passers-by during the watering operation can be reduced.

Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0027] Embodiment 1:

[0028] As shown in Figure 1 , 2 , 3, and 5, a sprinkler truck includes a sprinkler truck body 5 and an anti-spray cover assembly; the frame 1 is arranged above the water spraying port of the sprinkler truck body 5 and the frame 1 is installed on the bottom surface of the frame of the sprinkler truck body 5, and is used for blocking the upward flowing water and the water splashed from the ground.

[0029] The splash-proof cover plate assembly includes a frame 1 in a U-shaped structure. The upper cross beam of the frame 1 is installed on the frame of the sprinkler body 5 to complete the installation of the splash-proof cover plate assembly. A driving rotating shaft 2 is rotatably provided on the frame 1. One end of the driving rotating shaft 2 is connected to a driving motor 22 installed on the frame 1. That is to say, one end of the driving rotating shaft 2 is connected to the output end of the driving motor 22, and the other end is rotatably arranged on the frame 1 through a bearing. A gear 21 is provided on the driving rotating shaft 2. A supporting wheel 4 is rotatably provided on the frame 1 below the driving rotating shaft 2. There are two supporting wheels 4, and the two supporting wheels 4 and the gear 21 are distributed in an isosceles triangle. A cover plate body 3 is provided between the supporting wheel 4 and the gear 21. The top surface of the cover plate body 3 is provided with tooth patterns 32 meshing with the gear 21, and its bottom surface is in rolling contact with the supporting wheel 4. The gear 21 and the two supporting wheels 4 form a three-point support for the cover plate body 3, and under the meshing action of the gear 21 and the tooth patterns 32, the operation of extending or retracting the cover plate body 3 is completed.

[0030] The axis line of the driving rotating shaft 2 is arranged on one side of the vertical plane where the axis line of the supporting wheel 4 is located, and the cover plate body 3 is integrally in an upwardly arched structure. It can form a good clamping effect on the cover plate body 3. The arched cover plate body 3 can not only enhance the effect of blocking water splashes, but also cooperate with the design that the axis line of the gear 21 and the axis line of the supporting wheel 4 are in different planes to prevent the cover plate body 3 from tilting greatly.

[0031] The top surface of the cover plate body 3 is provided with a groove 31. The width of the groove 31 is not less than the thickness of the gear 21, and the tooth patterns 32 are arranged in the groove 31. The groove 31 can form a certain guidance for the gear 21 to prevent the cover plate body 3 from shifting. The tooth tips of the tooth patterns 32 do not exceed the top surface of the cover plate body 3, which can form a certain protection for the tooth patterns 32.

[0032] The bottom surface of the cover plate body 3 is provided with stripes or raised points. The stripes extend along the telescopic direction of the cover plate body 3 and can guide the splashed water. The raised points are evenly distributed on the cover plate body 3 and can offset the impact of the splashed sewage to effectively reduce the secondary splash of water.

[0033] Embodiment 2:

[0034] As shown in the appendix Figure 4 shown, other things remain unchanged. There are two grooves 31, and the two grooves 31 are respectively arranged at the two ends of the cover plate body 3. There are two gears 21, which are respectively meshed with the tooth patterns 32 in the grooves 31. At the same time, for the convenience of installing the gear 21 on the driving rotating shaft 2, the driving motor 22 is arranged outside the frame 1, and its output end extends into the frame 1 to drive the driving rotating shaft 2.

[0035] The utility model discloses a splash-proof cover assembly and a water sprinkler. The cover body is driven by the meshing of the gear and the tooth pattern. The supporting wheel supports the cover body at the bottom to guide the cover body to extend or retract outward. The cover body extends outward to block the water source that directly flies upward and splashes on the road surface, reducing the height of the water source and the splashing range, and reducing the impact on passers-by during the watering operation. When operating on a relatively narrow road, the structure of this case is particularly suitable, and the length of the cover body in the telescopic direction can be appropriately extended. When operating, the cover body extends close to the steps of the crosswalk to prevent most of the sewage from splashing upward and affecting passers-by.
