Description

Technical Field

[0001] This utility model relates to the field of vehicle cleaning technology, specifically to an intelligent sensing spray dust suppression system for engineering vehicles to prevent accidental spraying. Background Technology

[0002] Construction site dust control is crucial for the urban environment. Construction vehicles generate significant amounts of dust during transport, which not only affects air quality but can also harm workers' health and disrupt the daily lives of nearby residents. Cleaning construction vehicles can effectively suppress dust dispersion, maintain air humidity, and improve the construction environment.

[0003] Chinese utility model patent CN207128859U discloses a dust suppression spraying device for construction site transport vehicles, comprising a ramp, a base plate, and a housing. The ramp includes an upper ramp and a lower ramp, respectively positioned at opposite ends of the base plate. The base plate has a water outlet at its bottom and a drainage hole at its top. Housings are located on both sides of the base plate, each housing containing a frame. A second branch pipe connected to the housing is installed within the frame. Adjustable angle pressurized nozzles and flow-measuring nozzles are respectively mounted on the housing and frame. An infrared sensor is located at the front of the frame, which detects vehicle passage and controls the spraying module's activation and deactivation. This device is characterized by its ease of operation, low water consumption, and minimal pollution. However, if personnel or other equipment accidentally obstruct the infrared sensor, the spraying process will still be triggered, wasting water resources and potentially causing unnecessary interference to unrelated personnel or equipment. Utility Model Content

[0004] This utility model proposes an intelligent sensing spray dust suppression system for engineering vehicles, the purpose of which is to solve the problem of easy triggering of accidental spraying in the existing technology.

[0005] The technical solution of this utility model is as follows:

[0006] An intelligent sensing spray dust suppression system for engineering vehicles includes a water supply pipeline. The water supply pipeline adopts a modular assembly design and includes a main pipe, which comprises multiple pipe sections connected by quick-connect couplings. A first solenoid valve and a second solenoid valve are sequentially installed on the main pipe. The water supply pipeline also includes two sets of first branch pipes laid in the left-right direction and two sets of second branch pipes laid in the front-rear direction. The two sets of first branch pipes and the two sets of second branch pipes are connected by pipe joints to form a rectangular pipeline. The distance between the two sets of second branch pipes is greater than the width of the vehicle body. A high-pressure rotating nozzle is installed on the first branch pipe, and a fixed angle nozzle is installed on the second branch pipe.

[0007] It also includes infrared sensors, which include a first infrared sensor and a second infrared sensor respectively disposed on the rear side and the front side of the cleaning area.

[0008] It also includes a first relay electrically connected to the first infrared sensor for controlling the on / off state of the first solenoid valve, and a second relay electrically connected to the second infrared sensor for controlling the on / off state of the second solenoid valve.

[0009] Furthermore, the first branch pipe comprises multiple pipe segments connected in series, with the high-pressure rotary nozzle installed between adjacent pipe segments, and the first branch pipe and the high-pressure rotary nozzle are placed in a trench in the ground.

[0010] Specifically, the second branch pipe includes multiple pipe segments connected in series, with fixed angle nozzles installed between adjacent pipe segments.

[0011] Optionally, multiple fixed-angle nozzles are directly inserted into the second branch pipe. Each fixed-angle nozzle includes a plug and a fixed-angle nozzle. The lower end of the plug is a hemispherical rubber joint that is inserted into the second branch pipe. The upper end of the plug is a threaded connection end that extends out of the second branch pipe. The diameter of the threaded connection end is smaller than the diameter of the rubber joint. The threaded connection end is connected to the fixed-angle nozzle.

[0012] Optionally, water pipe supports for fixing the second branch pipe are also provided on the left and right sides of the cleaning area. The water pipe supports are multiple square steel pipes that are nested together. Adjacent square steel pipes are fastened together with bolts. Through holes are provided on the square steel pipes for fixing the angle nozzles to pass through.

[0013] Furthermore, the infrared sensor is mounted on the telescopic bracket.

[0014] Furthermore, the telescopic bracket includes a sleeve fixed to the ground, an internal telescopic rod that can move up and down, and screws for fixing the telescopic rod connected to the sleeve; an infrared sensor is installed at the upper end of the telescopic rod.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] (1) This utility model achieves a dual-sensor triggering mechanism by setting a first solenoid valve and a second solenoid valve connected in series and dual sensors respectively set at the front and rear ends of the cleaning area. That is, when the engineering transport vehicle fully enters the cleaning area, the first infrared sensor and the second infrared sensor are blocked at the same time, and the nozzle will be controlled to open. This can effectively reduce the risk of accidental spraying caused by single-sided sensor triggering, and reduce the interference and water waste caused by accidental spraying.

[0017] (2) This utility model provides a 360° rotating high-pressure spray nozzle at the front and rear of the cleaning area, and a fixed angle spray nozzle on the left and right sides of the cleaning area, so as to achieve comprehensive cleaning of the vehicle's surroundings and bottom.

[0018] (3) This utility model adopts a modular water supply pipeline, which realizes rapid assembly of the pipeline through standardized quick-connect couplings and tee components. This design supports free splicing of multi-segment pipelines, is easy to disassemble and assemble, and is applicable to vehicles of different specifications. At the same time, it can also realize the reuse of pipeline segments. In the scheme of "the second branch pipe is fixed on the water pipe bracket", the water pipe bracket adopts a telescopic design, and its length can also be adjusted as needed until it is compatible with the length of the second branch pipe.

[0019] (4) By setting up a sensor with a telescopic bracket, the height of the infrared sensor can be adjusted, ensuring that the infrared sensor can detect the vehicle chassis and enabling the infrared sensor to be adapted to more vehicle models. Attached Figure Description

[0026] The technical solution and effects of this utility model will be described in detail below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0027] like Figure 1 As shown, an intelligent induction spraying dust suppression system for engineering vehicles includes a water supply pipeline and an infrared sensor.

[0028] The water supply pipeline adopts a modular assembly design, including a main pipe 31 connected to the water supply interface via quick-connect couplings. The main pipe 31 comprises multiple pipe sections, each 4-6 meters in length, connected to each other via quick-connect couplings. A first solenoid valve 41 and a second solenoid valve 42 are sequentially installed on the main pipe 31.

[0029] Optionally, the main pipe 31 is equipped with a booster pump to provide a high-pressure water flow.

[0030] Optionally, a Y-type filter with a mesh size of ≥80 mesh may be installed at the water supply interface to prevent nozzle clogging.

[0031] The water supply pipeline also includes two sets of first branch pipes 32 laid in the left-right direction and two sets of second branch pipes 33 laid in the front-back direction. The two sets of first branch pipes 32 and the two sets of second branch pipes 33 are connected to form a rectangular pipeline through pipe joints, and one of the pipe joints is a tee joint. The end of the main pipe 31 is connected to the rectangular pipeline through the tee joint.

[0032] like Figure 2 Multiple high-pressure rotary nozzles 5 are installed on the first branch pipe 32. In this embodiment, the first branch pipe 32 includes multiple pipe sections connected in series, with the high-pressure rotary nozzles 5 installed between adjacent pipe sections. The high-pressure rotary nozzle 5 is a 360-degree automatic rotating sprinkler head with a three-pronged rotating nozzle structure at the top and an orifice diameter of 1.5 to 3 mm. The base of the high-pressure rotary nozzle 5 has two opposing interfaces that can be connected to the pipe sections on both sides. To ensure sealing, a sealing ring is provided at the connection. Alternatively, a Mag nozzle can be used as the high-pressure rotary nozzle 5, installed between adjacent pipe sections via a tee. The center distance between adjacent high-pressure rotary nozzles 5 is 0.4-0.6 meters, used for all-around washing of the chassis and tires. The first branch pipe 32 uses a DN25 PA water pipe with a pressure resistance ≥1MPa.

[0033] Preferably, the first branch pipe 32 and the high-pressure rotating nozzle 5 are placed in a trench in the ground to prevent damage to the pipes and nozzles when vehicles pass by.

[0034] The second branch pipe 33 comprises multiple pipe segments connected in series, with the fixed angle nozzle 6 installed between adjacent pipe segments via a tee. The fixed angle nozzle 6 is a universal, quick-connect nozzle, consisting of an aluminum tube and a copper nozzle mounted at the end of the aluminum tube. During installation, the lower end of the aluminum tube is connected to the tee connector, and then the nozzle is oriented towards the target position by bending the aluminum tube.

[0035] like Figure 3 In this embodiment, the fixed angle nozzle 6 adopts another structural form: multiple fixed angle nozzles 6 are directly inserted into the second branch pipe 33. The fixed angle nozzle 6 includes a plug 61 and a fixed angle nozzle 62. The lower end of the plug 61 is a hemispherical rubber joint that is inserted into the second branch pipe 33. The upper end of the plug 61 is a threaded connection end that extends out of the second branch pipe 33. The diameter of the threaded connection end is smaller than the diameter of the rubber joint. The threaded connection end is connected to the fixed angle nozzle 62.

[0036] The second branch pipe 33 uses a DN25 PA water pipe (flexible pipe) with a pressure rating of ≥1MPa.

[0037] Combination Figure 1 and Figure 3 As shown, water pipe supports 7 for fixing the second branch pipe 33 are also provided on both sides of the cleaning area. In this embodiment, the water pipe support 7 is a multi-segment square steel pipe that is nested together. Adjacent square steel pipes are fastened together with bolts, and through holes are opened on the square steel pipes for the fixed angle nozzles 6 to pass through. The second branch pipe 33 passes through the cavity of the water pipe support 7. When adapting to vehicles of different lengths, the length of the second branch pipe 33 can be adjusted by adding or removing pipe segments and joints. At the same time, the bolts installed on the outer square steel pipe are loosened, so that the inner end is separated from the inner square steel pipe. Then the length of the water pipe support 7 is adjusted until it matches the current length of the second branch pipe 33 and the through holes on the inner and outer square steel pipes overlap. Then the bolts are tightened again to complete the length fixation of the water pipe support 7.

[0038] like Figure 1 As shown, the infrared sensors include a first infrared sensor 11 and a second infrared sensor 12 respectively located on the rear side and front side of the cleaning area. The installation distance between them is set according to the vehicle model and does not need to be strictly aligned with the two first branch pipes 32. The closer the second infrared sensor 12 is to the vehicle's entry position, the earlier it can trigger the spray; the closer the first infrared sensor 11 is to the vehicle's exit position, the longer it can delay shutting off the spray. However, the distance between them should not be too close, otherwise they may be triggered simultaneously by other objects, failing to achieve the effect of avoiding incorrect spraying.

[0039] The system also includes a first relay and a second relay. The output terminal of the first infrared sensor 11 is connected to the input terminal of the first relay, and the normally open contact of the first relay is connected in series with the coil of the first solenoid valve 41 between the positive and negative terminals of the power supply. When the first infrared sensor 11 detects an object, its output terminal sends a signal to close the normally open contact of the first relay, thereby energizing and opening the first solenoid valve 41. When the first infrared sensor 11 does not detect an object, its output terminal does not output a signal, the normally open contact of the first relay opens, and the first solenoid valve 41 is de-energized and returns to the off state. Similarly, the output terminal of the second infrared sensor 12 is connected to the input terminal of the second relay, and the normally open contact of the second relay is connected in series with the coil of the second solenoid valve 42 between the positive and negative terminals of the power supply. When the second infrared sensor 12 detects an object, its output terminal sends a signal to close the normally open contact of the second relay, thereby energizing and opening the second solenoid valve 42. When the second infrared sensor 12 does not detect an object, the output terminal does not output a signal, the normally open contact of the second relay opens, and the second solenoid valve 42 is de-energized and returns to the cut-off state.

[0040] Optionally, this system uses an E3JK-DS30M1 infrared sensor with an IP67 protection rating and a response time of < 0.1 seconds as the sensing element.

[0041] Furthermore, such as Figure 4 As shown, the infrared sensor is height-adjustable, with a distance of 30-50 cm from the ground to ensure it can detect the vehicle chassis. The infrared sensor is mounted on the ground via a telescopic bracket. The telescopic bracket includes a sleeve 21 fixed to the ground, and a telescopic rod 22 that can move up and down is provided inside the sleeve 21. The infrared sensor is mounted on the upper end of the telescopic rod 22. A screw 23 is connected to the sleeve 21. After loosening the screw 23, the height of the telescopic rod 22 can be manually adjusted. After adjustment, tighten the screw 23 to fix the telescopic rod 22.

[0042] The following example illustrates the working principle of this system:

[0043] Standby state: When the vehicle does not enter the sensing area, the first infrared sensor 11 and the second infrared sensor 12 detect that the beam is unobstructed, the first solenoid valve 41 and the second solenoid valve 42 are both closed, and the system does not spray water.

[0044] Vehicles enter:

[0045] When the front of the vehicle enters the area of ​​the first infrared sensor 11, the beam of the first infrared sensor 11 is blocked, and the output signal is activated, opening the first solenoid valve 41. At this time, the second infrared sensor 12 has no output signal, and the second solenoid valve 42 remains in the closed state, so the system does not spray water. As the front of the vehicle continues to move forward and enters the area of ​​the second infrared sensor 12, the beam of the second infrared sensor 12 is blocked, and the second solenoid valve 42 opens, thereby opening the main pipe 31. High-pressure water flows into the first branch pipe 32 and the second branch pipe 33, reaching all nozzles, and begins to wash the vehicle chassis, tires, and sides.

[0046] Vehicles drove out:

[0047] When the rear of the vehicle leaves the area of ​​the first infrared sensor 11, the beam of the first infrared sensor 11 returns to normal, the first solenoid valve 41 closes, and the nozzle stops spraying water. When the rear of the vehicle leaves the area of ​​the second infrared sensor 12, the second solenoid valve 42 closes.

[0048] If personnel pass through the cleaning area, only the first infrared sensor 11 or the second infrared sensor 12 will be triggered. The first solenoid valve 41 and the second solenoid valve 42 will not open simultaneously, and the system will not start spraying water. When other equipment enters, due to insufficient length, the simultaneous triggering condition of both sensors is not met, and the system will not start spraying water either. It is evident that erroneous spraying will only be triggered if both infrared sensors are simultaneously and incorrectly blocked by personnel or equipment. However, in actual production, personnel and equipment rarely pass through the cleaning area, and there is a considerable distance between the two infrared sensors, making the probability of simultaneous blocking extremely low. Therefore, the dual-sensor triggering mechanism can effectively avoid the vast majority of erroneous spraying situations, eliminate potential hazards, and achieve the goal of conserving water resources.

[0049] It should be noted that, as will be apparent to those skilled in the art, this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. The scope of this utility model is defined by the claims rather than the foregoing description.
