[0002] With the increasing attention to PM2.5, the multifunctional dust suppression vehicle for spray dust suppression has become one of the necessary vehicles in most cities. The existing multifunctional dust suppression vehicle generally realizes single-launch hydraulic drive, solves the danger of electric leakage and electric shock, and protects the safety of the operator.

[0003] In the cold northern winter area, because the outdoor temperature is very low, the water in the spray device, the water device and the pipeline device needs to be discharged after the dust suppression vehicle is operated, otherwise the pipeline or the spray water will be blocked due to the ice formed by the residual water in the above devices, which affects the normal operation of the dust suppression vehicle. The existing dust suppression vehicle anti-freezing is mainly through manual drainage or gas bottle blowing drainage, which has poor drainage effect and low working efficiency, and affects the normal operation of the dust suppression vehicle.

[0021] Compared with the prior art, the present invention provides a defrosting system for a single-engine, fully hydraulic dust suppression vehicle spray water device, which has the following beneficial effects:

[0022] 1.

[0023] 2. The defrosting system of the spray and water sprinkler device of this single-engine fully hydraulic dust suppression truck heats the water in the hot water tank by circulating it, causing the ice-melting material stored in the storage cylinder to be evenly dispersed into the circulating water. This allows the heated water to mix quickly with the ice-melting material, thereby rapidly melting and thawing the ice in the spray device, water sprinkler device, and pipeline device. This allows the dust suppression truck to quickly enter its optimal working state and improves work efficiency. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Example:

[0034] Reference Figure 1 A defrosting system for a single-engine, fully hydraulic dust suppression truck spray and water sprinkler device includes: a hydraulic oil tank 1, a hydraulic pump 2, a main valve 3, a hydraulic actuator 4, an air-cooled radiator 5, a hydraulic temperature sensor 6, a spray system 7, a water sprinkler system 8, a motor pump 9, a hot water valve 10, a water temperature and level sensor 11, a controller 12, a special valve 13, a hot water tank 14, a heat exchanger 15, a water circuit control valve 16, a water storage tank 17, and a low-pressure water pump 18.

[0035] The hydraulic oil tank 1, hydraulic pump 2, main valve 3, hydraulic actuator 4, air-cooled radiator 5, hydraulic temperature sensor 6, special valve 13, and heat exchanger 15 are connected by hydraulic pipelines.

[0036] The spray system 7, sprinkler system 8, motor pump 9, hot water valve 10, hot water tank 14, heat exchanger 15, water control valve 16, water storage tank 17, and low-pressure water pump 18 are connected by water pipes.

[0037] The main valve 3, air-cooled radiator 5, controller 12, hydraulic temperature sensor 6, motor pump 9, water temperature and level sensor 11, special valve 13, heat exchanger 15, and water circuit control valve 16 are controlled by electrical wiring harnesses.

[0038] Furthermore, the special valve 13 includes a two-position two-way solenoid valve and a second relief valve. The maximum pressure set for the second relief valve is P', and the maximum pressure set for the relief valve of the main valve 3 is P'.

[0039] P <P。

[0040] Specifically, in cold northern winter regions, after the dust suppression truck is started and water is added, if blockage is found in the spraying device, water sprinkling device, and pipeline device, it switches to defrost mode. Controller 12 sends a control signal to water control valve 16, injecting water drawn from storage tank 17 by low-pressure water pump 18 into hot water tank 14. Water temperature and level sensor 11 continuously collects and sends water temperature and level signals to controller 12. When the water level collected by water temperature and level sensor 11 reaches the set water level value, controller 12 sends a control signal to water control valve 16 to cut off water injection into hot water tank 14, returning the water drawn by low-pressure water pump 18 to storage tank 17. At the same time, controller 12 sends control signals to main valve 3, special valve 13, and motor pump 9. At this time, the hydraulic oil in the main oil circuit flows through hydraulic oil tank 1, hydraulic pump 2, and main valve 3. The water flows through a special valve 13, a heat exchanger 15, and then back to the hydraulic oil tank 1. During the circulation process, the overflow valve set on the upper part of the special valve 13 overcomes the local pressure loss at the overflow port, allowing the hydraulic oil to heat up quickly. At this time, the water in the water circuit flows through the hot water tank 14, the motor pump 9, the water circuit control valve 16, and the heat exchanger 15, and then flows back to the hot water tank 14. This cycle continues, exchanging heat through the heat exchanger 15. When the water temperature signal collected and sent by the water temperature and water level sensor 11 reaches the set temperature value, the controller 12 sends a signal to the hot water valve 10 and the water circuit control valve 16 to open the hot water valve 10 and close the heat circulation water circuit. The hot water is then sent to the spray device, sprinkler device, and pipeline device by the motor pump 9, thereby thawing the devices that are blocked by ice, allowing the dust suppression vehicle to quickly enter the optimal working state and improve work efficiency.

[0041] Reference Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As a preferred technical solution of the present invention, the hot water tank 14 is provided with an inlet pipe 141 and an outlet pipe 142 at its upper and lower ends, respectively. A fixed bracket 143 is provided on the outside of the hot water tank 14. A storage cylinder 19 for storing ice-melting materials is provided on the fixed bracket 143. An intermittent discharge component 191 is provided at the bottom of the storage cylinder 19. A guide pipe 20 is provided between the storage cylinder 19 and the outlet pipe 142. An inlet 1421 communicating with the guide pipe 20 is opened at the top of the outlet pipe 142.

[0042] Furthermore, the intermittent discharge assembly 191 includes a partition 21 fixed inside the storage cylinder 19, which divides the storage cylinder 19 into a storage chamber and a working chamber. The partition 21 is provided with a first recess 211 for material to fall. The intermittent discharge assembly 191 also includes a drive motor 22 fixed to the top of the storage cylinder 19. The output end of the drive motor 22 is connected to a drive shaft 221, which is rotatably connected inside the storage cylinder 19. A first stirring plate 2211 is provided on the drive shaft 221, and a rotating plate 23 rotatably connected to the partition 21 is provided on the drive shaft 221. A second recess 231 that cooperates with the first recess 211 is provided on the rotating plate 23.

[0043] Specifically, when the water in the hot water tank 14 is circulated and heated, the drive motor 22 is controlled to run, causing the output end of the drive motor 22 to drive the drive shaft 221 to rotate. The drive shaft 221 drives the first stirring plate 2211 to stir the granular ice-melting material stored in the storage cylinder 19, preventing the material in the storage cylinder 19 from clumping due to moisture, which would affect the subsequent mixing of the ice-melting material with the water. When the drive shaft 221 rotates, it drives the rotating plate 23 to rotate. When the second concave hole 231 of the rotating plate 23 matches the first concave hole 211 of the partition plate 21, the ice-melting material in the storage chamber of the storage cylinder 19 automatically falls and mixes with the circulating water in the water outlet pipe 142 along the guide pipe 20 and the inlet 1421. This allows the heated water to quickly melt and thaw the ice in the spray device, sprinkling device, and pipeline device, enabling the dust suppression vehicle to quickly enter the optimal working state and improve work efficiency.

[0044] Reference Figure 3 , Figure 5 , Figure 6 and Figure 7 As a preferred technical solution of the present invention, both the partition 21 and the rotating plate 23 are set as conical plates; specifically, the partition 21 and the rotating plate 23 are set as conical plates, which can facilitate the melting ice material placed in the storage cavity to fall naturally down the slope, and avoid the melting ice material in the storage cavity from accumulating at the bottom and being unable to be discharged effectively.

[0045] Reference Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7As a preferred technical solution of the present invention, a grinding body 24 is movably connected inside the working chamber of the storage cylinder 19. Several evenly distributed sieve holes are opened at the bottom of the working chamber. The sieve hole diameter is smaller than the diameter of the second concave hole 231. The grinding body 24 moves against the bottom inner wall of the working chamber. A connecting rod 241 is provided between the grinding body 24 and the drive shaft 221. Specifically, when the drive shaft 221 rotates, it drives the grinding body 24 to move in the working chamber at the bottom of the storage cylinder 19, so that the grinding body 24 grinds the granular ice-melting material placed at the bottom side of the working chamber, so that the granular material is ground into powder. The powder enters the water outlet pipe 142 through the sieve holes and the guide pipe 20 to mix with the circulating water, thereby improving the mixing effect and mixing efficiency of the material and the water. This allows the heated water to quickly melt and thaw the ice in the spray device, sprinkling device and pipeline device, so that the dust suppression vehicle can quickly enter the optimal working state and improve the working efficiency.

[0046] Reference Figure 5 and Figure 6 As a preferred technical solution of the present invention, the inner wall of the working chamber is rotatably connected to a swing rod 28 that moves against the connecting rod 241 via a pin. A torsion spring for resetting the swing rod 28 is provided on the pin. A rubber hammer 281 is connected to the end of the swing rod 28 away from the inner wall of the working chamber, and the rubber hammer 281 moves against the inner wall of the working chamber. Specifically, when the connecting rod 241 rotates with the drive shaft 221, it intermittently applies force to the swing rod 28. When the connecting rod 241 no longer applies force to the swing rod 28, the swing rod 28 resets and rotates under the force of the torsion spring outside the pin. The swing rod 28 drives the rubber hammer 281 to strike the bottom side of the storage cylinder 19, causing the storage cylinder 19 to shake. It should be noted that the storage cylinder 19 can be flexibly connected to the fixed bracket 143 and the guide pipe 20 to adapt to the vibration of the storage cylinder 19, so that the ice-melting material ground into powder can fall and be discharged quickly, thereby improving work efficiency.

[0047] Reference Figure 3 , Figure 4 and Figure 5 As a preferred technical solution of the present invention, a support frame 1422 is provided inside the water outlet pipe 142. A stirring rod 25 connected to the grinding body 24 is rotatably connected inside the support frame 1422. Several second stirring plates 251 are provided on the stirring rod 25 at equal intervals. Specifically, when the grinding body 24 grinds the material, it can drive the stirring rod 25 to rotate inside the water outlet pipe 142. The rotation of the stirring rod 25 will drive the second stirring plates 251 to stir the ice-melting material and water in the water outlet pipe 142, so that the water and material are quickly mixed, improving the mixing effect and mixing efficiency of the material. In turn, the heated water can quickly melt and thaw the ice in the spray device, sprinkling device and pipeline device, so that the dust suppression vehicle can quickly enter the optimal working state and improve the working efficiency.

[0048] Reference Figure 2 ,Figure 3 , Figure 4 and Figure 5 As a preferred technical solution of the present invention, an arc-shaped guide vane 26 is fixedly installed inside the water outlet pipe 142. The inner wall of the side of the water outlet pipe 142 away from the hot water tank 14 is set as a material discharge channel 27. An electric heating plate 271 is installed on both the arc-shaped guide vane 26 and the water outlet pipe 142. Specifically, the arc-shaped guide vane 26 installed inside the water outlet pipe 142 can guide the water flowing from the hot water tank 14 to the water outlet pipe 142, avoiding the water from flowing and impacting the storage cylinder 19, causing the inside of the storage cylinder 19 to become wet, thus preventing the ice in the storage cylinder 19 from melting. The material is completely soaked, increasing the cost of using the de-icing material. Furthermore, an electric heating plate 271 is installed on the side wall of the arc-shaped guide plate 26 and the water outlet pipe 142 to heat the material discharge channel 27. This prevents the powdered de-icing material from contacting the wet arc-shaped guide plate 26 and the side wall of the water outlet pipe 142 when it passes through the material discharge channel 27. This causes the de-icing material to adhere to the material discharge channel 27, preventing it from effectively mixing with the circulating water in the water outlet pipe 142. This affects the subsequent speed at which the water melts and thaws the ice in the spraying device, sprinkling device, and pipeline device.

[0049] Reference Figure 2 , Figure 3 and Figure 5 As a preferred technical solution of the present invention, the ice-melting material stored in the storage cylinder 19 is industrial salt; the specific ice-melting material is set as industrial salt, but is not limited to this. Industrial salt can reduce the cost of use. The main component of salt is sodium, which is an ice melting agent. It can accelerate the melting and thawing speed of the ice in the spraying device, sprinkling device and pipeline device, so that the dust suppression vehicle can quickly enter the best working state and improve work efficiency.
