Description

Technical Field

[0001] The utility model relates to a water cannon, in particular to a front water cannon device for a sprinkler truck. Background Art

[0002] Air pollution, urban development, and environmental protection are all driving the growing importance of greening in China's development. Consequently, greening departments across China invest significant manpower and resources annually to maintain and water the flowers, trees, lawns, and various vegetation within their respective territories. The operation of a vehicle-mounted sprinkler involves the driver manipulating the vehicle equipped with the spraying equipment. A worker, behind the vehicle's onboard water tank, waters the area using a hose and a water pump connected to a spray gun. In the past, improper coordination between the worker behind the vehicle and the driver in the cab during this process could easily lead to accidents. Furthermore, the vehicle's slow motion can cause the hose to swing, making it difficult for the worker to hold the hose, which can cause the gun to slip out of their hands and even injure others.

[0003] For safety reasons, some irrigation trucks have their spray guns mounted on the rear of the truck with brackets. However, this still requires an operator to operate the spray guns. This leaves workers exposed to the scorching heat, posing health risks such as heatstroke and injuries. Furthermore, the high-pressure water spray creates a recoil force, and prolonged use can cause the gun to loosen due to internal stress. Therefore, the use of a vehicle-mounted automatic spraying device is more convenient and intelligent, and is a pressing technical issue that needs to be addressed. Utility Model Content

DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. The embodiments of the basic utility model and all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present utility model.

[0022] according to Figure 1 、 Figure 2 and Figure 3As shown, a front water cannon device for a sprinkler truck includes a water cannon assembly 18, and the water cannon assembly 18 includes an upper accommodating tube 3, a lower accommodating tube 5 and a diverter tube 2. The upper accommodating tube 3 is rotatably connected to the lower accommodating tube 5 through a rotating connector. The upper accommodating tube 3 is communicated with the input end of the diverter tube 2, and the output end of the diverter tube 2 is divided into two sections and the output end ports of the diverter tube 2 are relatively arranged. In this way, the water flow is relatively converged to reduce the impact force of the water flow in the pipe, thereby reducing the recoil force when the water flow is sprayed out, and reducing the internal stress of the device. The connectors become loose, thereby extending the overall service life of the device. The output ends of the diverter pipe 2 are rotationally connected to the T-tube 12, and the output ends of the T-tube 12 are communicated with the gun head assembly 1. The diverter pipe 2 is provided with an up and down rotating module for driving the T-tube 12 to rotate in the vertical direction. In this way, it is used to adjust the spraying height and the spraying range. A left and right rotating module for driving the upper accommodating pipe 3 to rotate in the horizontal direction is provided between the upper accommodating pipe 3 and the lower accommodating pipe 5. Through this design, the garden flowers and plants on both sides of the road can be sprayed.

[0023] This design is set at the front end of the sprinkler truck to achieve automatic swinging to adjust the direction of the water cannon and realize automatic spraying.

[0024] according to Figure 4 As shown, the T-tube 12 is provided with a guide portion 15 for guiding the incoming water flow to the output end of the T-tube 12, and both sides of the guide portion 15 form an arc surface facing the input end of the T-tube 12, so that the water flow hits the arc surface and is then introduced into the output end of the T-tube 12 and then discharged. The guide portion 15 has the function of guiding the flow.

[0025] The gun head assembly 1 is provided with an adjustment module 16 for switching the spraying mode of the gun head assembly 1. The design of the adjustment module 16 helps to improve the function of the gun head assembly 1, thereby adjusting the range and jet state of the water cannon.

[0026] according to Figure 1 As shown, the left-right rotating module includes a left-right rotating motor 9 installed on the upper accommodating tube 3 and a gear ring 6 provided on the lower accommodating tube 5. The gear 8 connected to the output end of the left-right rotating motor 9 is engaged with the gear ring 6. The left-right rotating motor 9 drives the gear 8 to rotate, thereby driving the upper accommodating tube 3 to rotate in the horizontal direction, so that when the sprinkler truck 19 is driving on the road, the gun head assembly 1 swings left and right toward the flowers, plants and trees on both sides of the roadside for spraying.

[0027] according to Figure 3As shown, the upper and lower rotating modules adopt a pneumatic rod 14, one end of the pneumatic rod 14 is hinged to the diverter tube 2, and the other end is hinged to the T-tube 12 so that the gun head assembly 1 can be rotated in the vertical direction to adjust the range and scope, and a triangular positioning is formed between the pneumatic rod 14, the T-tube 12 and the diverter tube 2, which further ensures the stability of the device during spraying and the stability of the device during operation.

[0028] according to Figure 2 As shown, the up and down rotating module includes an up and down rotating motor 13 provided on the diversion pipe 2 and a gear ring 2 11 provided on the T-tube 12. The gear 2 17 connected to the output end of the up and down rotating motor 13 is engaged with the gear ring 2 11 through a toothed belt 10, so that when the up and down rotating motor 13 drives the gear 2 17 to rotate, the gear 2 17 and the gear ring 2 11 rotate synchronously, so that the gun head assembly 1 swings in the vertical direction to adjust the spraying distance and range.

[0029] The rotary connection piece is preferably a pipe rotary joint 4 so that the upper accommodating tube 3 can rotate relative to the lower accommodating tube 5 .

[0030] according to Figure 5 As shown, the water cannon assembly 18 is arranged on the mounting seat 7, and the mounting seat 7 is arranged at the front end of the sprinkler truck 19. The mounting seat 7 plays a role in supporting and fixing the water cannon assembly 18, and the water cannon assembly 18 is connected to the water tank through a pipeline.

[0031] Working principle: The sprinkler truck 19 is connected to the water cannon assembly 1 through a pipeline. The water flows into the lower receiving tube 5, the upper receiving tube 3, the diversion tube 2, and the T-tube 12 in sequence and is sprayed out from the gun head assembly 1. The left and right rotation module drives the upper receiving tube 3 to rotate in the horizontal direction, and controls the gun head assembly 1 to swing left and right so that the car can control the gun head assembly 1 to spray the green areas on both sides of the road while moving. The up and down rotation module drives the T-tube 12 to rotate in the vertical direction, and controls the gun head assembly 1 to swing up and down to adjust the spraying area and range.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
