Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression vehicles, in particular to a spray counting device for a dust suppression vehicle. Background Technique

[0002] The dust suppression vehicle can spray dust suppressant through a spray head. By spraying the dust suppressant on the surface of granular bulk goods such as coal loaded in the cargo compartments of trains or trucks, a protective film can be formed to prevent dust generation during transportation. There are two modes for the dust suppression vehicle to spray the dust suppressant. One is the manual mode, where the spraying of the dust suppressant is manually turned on and off, and the spraying duration is controlled manually. The other is the automatic mode. Under the automatic mode, there are two modes: continuous spraying and intermittent spraying. In the automatic mode, the passing cargo compartments are automatically recognized for automatic continuous spraying or automatic intermittent spraying of the dust suppressant. Obviously, for trains passing continuously with a large number of cargo compartments, automatic spraying is more convenient.

[0003] However, in the existing intermittent spraying mode under the automatic mode of the dust suppression vehicle, only the cargo compartments and the gaps between the cargo compartments of the train are recognized. The spray counting only sprays for a specified number of seconds when recognizing the cargo compartments and stops spraying for a specified number of seconds when recognizing the gaps between the cargo compartments. However, during actual spraying, the speed of the train passing by is variable, and the spraying flow rate of the dust suppressant remains unchanged, which will cause the thickness of the protective film formed by the dust suppressant to be uneven, and the dust prevention effect to be different. When the speed of the cargo compartment is slow, the thickness of the dust suppressant protective film is large, and the dust suppression effect is improved. When the speed of the cargo compartment is fast, the thickness of the dust suppressant protective film is relatively small, and the dust suppression effect decreases. There are defects, so a new spray counting device for a dust suppression vehicle that can adjust the thickness of the dust suppressant protective film according to the passing speed of the cargo compartment is proposed. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the utility model provides a spray counting device for a dust suppression vehicle, which is used to solve the problem that the spray counting device of the spray agent in the existing technology cannot adjust the thickness of the protective film according to the passing speed of the train cargo compartment to ensure the dust suppression effect.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A spray counting device for a dust suppression vehicle includes a controller, a display, and a flow meter installed on the dust suppressant delivery pipe. An electromagnetic valve is also installed on the dust suppressant delivery pipe. The dust suppressant delivery pipe is connected to a spray pipe through a connecting pipe. A fixed frame is fixedly installed above the position corresponding to the spray head on the spray pipe. A gear turntable is fixedly installed on the fixed frame. An installation platform is rotatably connected to the gear turntable through a rotating shaft. A rotary motor, a high-definition camera, and a laser speedometer are installed on the installation platform. The output shaft of the rotary motor penetrates downward through the installation platform and is fixed with a driving gear. The driving gear is in transmission engagement with the tooth groove on the gear turntable.

[0007] The high-definition camera, laser speedometer, and flowmeter are all signal-connected to the controller, and the controller is signal-connected to the rotary motor, display, solenoid valve, and the flow pump installed at the input end of the dust suppressant delivery pipe.

[0008] Preferably, a traction cable is installed on the spray pipe, and limiting through grooves corresponding to the positions of the traction cable are provided on both sides of the fixing frame.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1-3 shown, the present invention provides a technical solution: a dust suppression vehicle spray counting device, including a controller 1, a display 2, and a flowmeter 4 installed on a dust suppressant delivery pipe 3. A solenoid valve 5 is also installed on the dust suppressant delivery pipe 3. The dust suppressant delivery pipe 3 is connected to a spray pipe 7 through a connecting pipe 6. A fixed frame 9 is fixedly installed above the position corresponding to the spray head 8 on the spray pipe 7. A gear turntable 10 is fixedly installed on the fixed frame 9. An installation platform 11 is rotatably connected to the gear turntable 10 through a rotating shaft. A towing cable 17 is installed on the spray pipe 7. Limit through slots 18 corresponding to the position of the towing cable 17 are provided on both sides of the fixed frame 9. The limit through slots 18 are vertical long slots;

[0021] A rotary motor 12, a high-definition camera 13, and a laser speedometer 14 are installed on the installation platform 11. The output shaft of the rotary motor 12 penetrates downward through the installation platform 11 and is fixed with a driving gear 15. The driving gear 15 is in transmission engagement with the tooth slots on the gear turntable 10. The fixed frame 9, the gear turntable 10, and the installation platform 11 are coaxially arranged. The high-definition camera 13 and the laser speedometer 14 are installed and fixed through installation brackets 19 symmetrically arranged left and right on the installation platform 11. The installation angles of the high-definition camera 13 and the laser speedometer 14 are the same. The rotary motor 12 is installed directly behind the position between the high-definition camera 13 and the laser speedometer 14;

[0022] As Figure 4As shown in the figure, the high-definition camera 13, the laser speedometer 14, and the flow meter 4 are all signal-connected to the controller 1. The controller 1 is signal-connected to the rotary motor 12, the display 2, the solenoid valve 5, and the flow pump 16 installed at the input end of the dust suppressant delivery pipe 3. The high-definition camera 13 and the laser speedometer 14 acquire the images when the train passes by. The controller 1 obtains the length of the train cargo box, the length of the cargo box gap, and the passing speed through the signals received by the high-definition camera 13 and the laser speedometer 14, so as to obtain the passing time of the train cargo box and the passing time of the cargo box gap. When the train cargo box passes by, the sprinkler head 8 sprays the dust suppressant. When encountering the cargo box gap, the sprinkler head 8 stops spraying the dust suppressant to avoid waste.

[0023] Working principle: The high-definition camera 13 and the laser speedometer 14 acquire the image signals when the train cargo box passes by. The controller 1 calculates the length of the cargo box and the cargo box gap, as well as the passing time and speed through the signals of the high-definition camera 13 and the laser speedometer 14, and at the same time performs counting. According to the time, it is determined to spray the dust suppressant when the train cargo box passes by, and stop spraying the dust suppressant when encountering the cargo box gap; at the same time, according to the increase or decrease of the speed, the opening degree of the solenoid valve 5 and the power of the flow pump 16 are correspondingly increased or decreased, so as to change the spraying flow rate of the inhibitor, ensure that the inhibitor is not wasted when the cargo box is at low speed, and ensure the thickness of the protective film when the cargo box is at high speed, achieving the effect of intelligent dust suppression.
