Description

Technical Field

[0001] The utility model relates to the technical field of sprinkler trucks, in particular to a front protective device for an electric sprinkler truck. Background Art

[0002] Electric sprinkler trucks are specialized vehicles powered by electricity and primarily used for urban road cleaning, landscaping watering, and dust suppression. Compared to traditional fuel-powered sprinkler trucks, these vehicles offer advantages such as lower noise, zero tailpipe emissions, and improved environmental friendliness, meeting the environmental protection requirements of modern cities.

[0003] Currently, sprinkler trucks on the market usually have high-pressure nozzles on the front side of the vehicle so that the sprayed water can clean the ground. However, when the vehicle is driving, if it encounters higher obstacles on higher ground, the high-pressure nozzles at the lower position will be damaged by collision. For this reason, we have proposed a front protective device for electric sprinkler trucks. Utility Model Content

[0004] The purpose of the utility model is to provide a front protection device for an electric sprinkler truck, which has the advantages of being able to automatically monitor the height of ground obstacles and lift the high-pressure sprinkler head to prevent the sprinkler head from being damaged by impact.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a front protective device for an electric sprinkler truck, comprising a reinforcing rib and an electric push rod, the reinforcing rib being fixed to the front side of the sprinkler truck head, the electric push rod being fixed to the left and right sides of the sprinkler truck head, a mounting plate being fixed on the surface of the reinforcing rib, a buffer mechanism being installed on the surface of the mounting plate, a buffer plate being provided on one side of the mounting plate, a movable plate being fixed to the bottom of the electric push rod, a diversion pipe being fixed to the bottom of the movable plate, a corrugated pipe being connected to the surface of the diversion pipe, a first high-pressure nozzle and a second high-pressure nozzle being connected to the surface of the diversion pipe, a mounting seat being fixed to the top of the mounting plate, a movable platform being hinged on the surface of the mounting seat, a laser sensor being fixed on the surface of the movable platform, and a controller being fixed to the inner wall of the mounting plate.

[0006] As a preferred front protective device for an electric sprinkler truck of the present invention, the buffer mechanism includes a support plate, which is fixed to the surface of the mounting plate. There are multiple support plates, and two first springs are fixed to the surface of the support plate. A first slider is fixed to the surface of the first spring, and the first slider is slidingly connected to the surface of the support plate. The surface of the first slider is hinged with a first connecting plate, and the surface of the first connecting plate is hinged with a combination plate, and the surface of the combination plate is fixedly connected to the buffer plate.

[0007] As a preferred front protective device for an electric sprinkler truck of the present invention, the surface of the combined plate is hinged with two second connecting plates, the surface of the second connecting plate is hinged with a second slider, the second slider is slidably connected to the surface of the support plate, and a second spring is fixed between the second sliders on both sides.

[0008] As a preferred front protection device for an electric sprinkler truck of the present invention, four extension plates are fixed to the surface of the combination plate, an airbag is fixed to the surface of the extension plate, and the surface of the airbag is fixedly connected to the surface of the support plate.

[0009] As a preferred front protective device for an electric sprinkler truck of the present invention, a slide bar is fixed to the surface of the support plate, and the slide bar passes through the first slider and the second slider, and the first slider and the second slider are both slidably connected to the surface of the slide bar.

[0010] As a preferred embodiment of the front protective device for an electric sprinkler truck of the present invention, a brush plate is fixed to the inner wall of the mounting plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] In the present utility model, when the laser emitted by the laser sensor is blocked by a higher obstacle on the ground, the laser sensor will transmit a signal to the controller, and the controller will control the electric push rod to retract, so that the movable plate can drive the diverter pipe to move upward, and the bellows can also be extended and retracted to ensure that the diverter pipe can move normally. After the diverter pipe moves upward, the first high-pressure nozzle will enter the inner side of the mounting plate, so that the obstacle will not contact the first high-pressure nozzle and the second high-pressure nozzle, thereby ensuring the safety of the two high-pressure nozzles during vehicle driving. At the same time, the buffer plate can also absorb the impact force on the front side of the vehicle. When a vehicle is driving in front of the vehicle body, causing stones on the ground to be lifted up and move toward the surface of the buffer plate, the buffer plate can absorb the impact force and disperse the impact force to the buffer mechanism. The buffer mechanism can disperse the impact on the buffer plate to prevent flying stones from damaging the first high-pressure nozzle, thereby further improving the safety of the first high-pressure nozzle.

[0020] See also Figure 1-6 , a front protective device for an electric sprinkler truck, comprising a reinforcing rib 1 and an electric push rod 7, the reinforcing rib 1 is fixed to the front side of the sprinkler truck head, the electric push rod 7 is fixed to the left and right sides of the sprinkler truck head, a mounting plate 2 is fixed on the surface of the reinforcing rib 1, a buffer mechanism 3 is installed on the surface of the mounting plate 2, a buffer plate 15 is provided on one side of the mounting plate 2, a movable plate 8 is fixed to the bottom of the electric push rod 7, a shunt pipe 9 is fixed to the bottom of the movable plate 8, a bellows 10 is connected to the surface of the shunt pipe 9, a first high-pressure nozzle 11 and a second high-pressure nozzle 12 are connected to the surface of the shunt pipe 9, a mounting seat 4 is fixed to the top of the mounting plate 2, a movable platform 5 is hinged on the surface of the mounting seat 4, a laser sensor 6 is fixed on the surface of the movable platform 5, a controller 14 is fixed to the inner wall of the mounting plate 2, and the controller 14 is electrically connected to the electric push rod 7 and the laser sensor 6;

[0021] The reinforcing rib 1 is used to be fixed to the front side of the vehicle, the electric push rod 7 is used to be fixed to the left and right sides of the vehicle, the bellows 10 is used to communicate with the water supply pipeline of the sprinkler truck, and the movable platform 5 can adjust the angle on the surface of the mounting seat 4 so that the laser alignment position emitted by the laser sensor 6 can be adjusted. When the laser emitted by the laser sensor 6 is blocked by a higher obstacle on the ground, the laser sensor 6 will transmit the signal to the controller 14, and the controller 14 will control the electric push rod 7 to shrink so that the movable plate 8 can drive the shunt pipe 9 to move upward. At the same time, the bellows 10 can also be retracted to ensure that the shunt pipe 9 can move normally. After the shunt pipe 9 moves upward, The first high-pressure nozzle 11 will enter the inner side of the mounting plate 2, so that obstacles will not come into contact with the first high-pressure nozzle 11 and the second high-pressure nozzle 12, thereby ensuring the safety of the two high-pressure nozzles during vehicle driving. At the same time, the buffer plate 15 can also absorb the impact force on the front side of the vehicle. When a vehicle is driving in front of the vehicle body, causing stones on the ground to be lifted and moved toward the surface of the buffer plate 15, the buffer plate 15 can absorb the impact force and disperse the impact force to the buffer mechanism 3. The buffer mechanism 3 can disperse the impact on the buffer plate 15 to prevent flying stones from damaging the first high-pressure nozzle 11, thereby further improving the safety of the first high-pressure nozzle 11.

[0022] Furthermore, the buffer mechanism 3 includes a support plate 301, which is fixed to the surface of the mounting plate 2. There are multiple support plates 301, two first springs 302 are fixed to the surface of the support plate 301, a first slider 303 is fixed to the surface of the first spring 302, the first slider 303 is slidably connected to the surface of the support plate 301, a first connecting plate 305 is hinged to the surface of the first connecting plate 305, a combination plate 304 is hinged to the surface of the first connecting plate 305, and the surface of the combination plate 304 is fixedly connected to the buffer plate 15;

[0023] When the buffer plate 15 is hit, the buffer plate 15 will drive the combination plate 304 to move toward the support plate 301. At this time, the first connecting plate 305 will rotate and make the first sliders 303 on both sides move in the opposite direction, so that the first spring 302 can be compressed and deformed, thereby having a buffering effect on the buffer plate 15, thereby improving the protection effect of the first high-pressure nozzle 11 and the front of the vehicle.

[0024] Furthermore, the surface of the combined plate 304 is hinged with two second connecting plates 311, and the surface of the second connecting plate 311 is hinged with a second slider 306. The second slider 306 is slidably connected to the surface of the support plate 301, and a second spring 307 is fixed between the second sliders 306 on both sides.

[0025] When the combination plate 304 moves toward the support plate 301 , the second connecting plate 311 rotates, allowing the second sliders 306 on both sides to move toward each other, thereby compressing the second spring 307 to further disperse the impact force on the buffer plate 15 .

[0026] Furthermore, four extension plates 309 are fixed to the surface of the combined plate 304, and air bags 310 are fixed to the surface of the extension plates 309. The surface of the air bags 310 is fixedly connected to the surface of the support plate 301.

[0027] When the combined plate 304 moves toward the position of the support plate 301, the extension plate 309 squeezes the airbag 310, and the airbag 310 can further buffer the impact force, thereby improving the protection effect of the front side of the vehicle and the first high-pressure nozzle 11 below.

[0028] Furthermore, a slide bar 308 is fixed to the surface of the support plate 301 , and the slide bar 308 passes through the first slider 303 and the second slider 306 , and the first slider 303 and the second slider 306 are both slidably connected to the surface of the slide bar 308 ;

[0029] The first slider 303 and the second slider 306 can both slide on the surface of the slide bar 308 , so that they can obtain a guiding effect and avoid moving toward the position where the combination plate 304 is located.

[0030] Furthermore, a brush plate 13 is fixed to the inner wall of the mounting plate 2;

[0031] When the electric push rod 7 drives the movable plate 8 to move upward, the surface of the first high-pressure nozzle 11 can contact the brush on the surface of the brush plate 13, so that the brush plate 13 can clean the surface of the first high-pressure nozzle 11, so as to clean the impurities attached to the surface of the first high-pressure nozzle 11.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
