Description

Technical Field

[0001] This disclosure relates to the field of dust removal technology, and in particular to a dust suppression device and a dust suppression vehicle. Background Technology

[0002] Open-pit mines generate large amounts of dust during blasting, excavation, transportation, and crushing operations. In particular, large quantities of rock fragments and soil particles are suspended in the air during handling and processing, forming dust. In addition, open-pit mines are usually located in open terrain, and when the wind is strong, the dust is easily dispersed into the surrounding environment, exacerbating the degree of dust pollution.

[0003] High concentrations of dust reduce visibility, making it difficult for autonomous driving systems to accurately perceive their surroundings and their own location. This increases the risk of collisions between autonomous vehicles and obstacles, other vehicles, or people. It can also cause unmanned mining trucks to deviate from their planned routes or fail to reach their destinations accurately, and may limit their speed, reducing the efficiency of mine transportation. Furthermore, long-term exposure to high concentrations of dust can harm the health of employees, causing respiratory and lung diseases. Utility Model Content

[0050] To enable those skilled in the art to better understand the technical solutions of this disclosure, and to fully understand and implement the process of how this disclosure applies technical means to solve technical problems and achieve corresponding technical effects, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, not all embodiments. The embodiments of this disclosure and the various features within them can be combined with each other without conflict, and the resulting technical solutions are all within the protection scope of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort should fall within the protection scope of this disclosure.

[0051] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0052] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0053] This embodiment provides a dust suppression device that can be applied to environments with a lot of dust to suppress dust, especially suitable for open-pit mines. Furthermore, the dust suppression device is applied in a dust suppression vehicle, which travels to the target area to suppress dust.

[0054] like Figures 1 to 3 As shown, this embodiment provides a dust suppression device, including: a water tank 1, a spray gun 2, and a processor. The water tank 1 is used to hold liquid and has an inlet 11 and an outlet 12. The inlet 11 is connected to a water source through a pipe to inject liquid into the water tank 1. The outlet 12 is connected to the spray gun 2 through a pipe. The spray gun 2 is used to convert the liquid in the water tank 1 into a mist of droplets and spray them out, forming mist-like water droplets in the air to adsorb dust.

[0055] The top of water tank 1 has an opening 13, and the chemical reagent kit is placed above the opening 13. It can be opened manually or automatically. For automatic opening, a reagent kit opening mechanism is connected to the chemical reagent kit to drive it to open or close. When opened, the substance in the chemical reagent kit falls into water tank 1, mixes with the liquid in water tank 1, and is then sprayed out by spray gun 2, further improving the dust removal effect. The substance in the chemical reagent kit can be set according to the type of dust; for example, calcium salts, magnesium salts, etc., can be added. These substances have good hygroscopicity and adhesion, enabling them to quickly adsorb dust and reduce the movement and diffusion of dust particles in the air.

[0056] For example, the reagent kit opening mechanism can use a drive motor to drive a worm gear mechanism, which drives the lid of the chemical reagent kit to move and open, so that the chemical reagent kit substances fall into the water tank.

[0057] The water tank 1 is equipped with a stirrer 3, which stirs the liquid in the water tank 1 to mix the substances entering the water tank 1 with the liquid evenly.

[0058] The water tank 1 is also equipped with a liquid level sensor 51 for detecting the liquid level in the water tank. The liquid level sensor 51 can be an ultrasonic sensor, a contact switch, or other devices, and is installed on the top or side wall of the water tank 1.

[0059] The processor is connected to the liquid level sensor 51 to obtain the liquid level in the water tank detected by the liquid level sensor 51, and controls the valve at the water inlet 11 of the water tank 1 to open or close according to the liquid level in the water tank.

[0060] The processor is connected to the stirrer 3 to control the start and stop of the stirrer 3. For example, after the substance in the chemical reagent kit enters the water tank 1, the stirrer 3 is controlled to start stirring the liquid, and the stirring stops after a period of time.

[0061] The processor is connected to the reagent kit opening mechanism to control the operation of the reagent kit opening mechanism, so as to open the chemical reagent kit and add chemical substances into the water tank 1.

[0062] The processor is also connected to spray gun 2 to control the start and stop of spray gun 2.

[0063] The technical solution provided in this embodiment uses a water tank with an inlet and an outlet. The top of the water tank has an opening. A level sensor is installed on the water tank to detect the liquid level inside. A stirrer is installed inside the water tank. A chemical reagent kit is located above the opening of the water tank. A spray gun is connected to the outlet of the water tank to convert the liquid in the tank into a mist-like droplets for spraying. A processor is connected to the level sensor to obtain the water level detected by the sensor, to the stirrer to control its start and stop, and to the spray gun to control its start and stop. This enables the spraying of a mist-like droplets containing chemical substances into a dusty environment to adsorb dust, reduce dust movement and diffusion, thereby improving environmental visibility, ensuring the normal operation of the unmanned vehicle, and reducing harm to the health of employees.

[0064] Based on the above technical solution, the processor can be a Jetson Xavier module, which connects to the liquid level sensor via a UART interface. Specifically, the liquid level sensor can be a CTE / CTW9000 model, with its sensing end located inside water tank 1 to acquire the liquid level information and send it to the Jetson Xavier module. The CTE / CTW9000 is a submersible hydrostatic liquid level sensor with excellent media compatibility, suitable for various industrial liquids. This series of liquid level sensors uses a stainless steel fully welded encapsulated pressure sensor element, without internal elastic seals, and features a small-diameter stainless steel housing design. This series of sensors has self-calibration and temperature self-compensation capabilities, and can provide analog output amplified signals. Older models of water trucks commonly used in open-pit mines, such as the PX40 and PX65, lack clear liquid level limiting devices, allowing water to be added until overflow, leading to excessive pressure on the vehicle body and affecting vehicle availability. This embodiment effectively solves this problem by incorporating a liquid level sensor.

[0065] The mixer 3 is connected to the GPIO pins of the Jetson Xavier module via a motor drive module (L298N). Specifically, the control pins of the motor drive module L298N (such as ENA, ENB, IN1, IN2, IN3, IN4) are connected to the GPIO pins of the Jetson Xavier, so that the Jetson Xavier can control the start, stop, and direction of the mixer 3's motor.

[0066] Spray gun 2 can be a metal rocker arm spray gun, mounted on top of the dust suppression vehicle. Spray gun 2 is connected to water tank 1 via a water pipe. Spray gun 2 is connected to the GPIO pins of the Jetson Xavier module via a four-phase stepper motor and a stepper motor driver. Spray gun 2 can moisten dust and particulate matter in the air by spraying water mist or other liquids, causing them to settle to the ground or be fixed on surfaces, thereby reducing the concentration of dust in the air and reducing air pollution.

[0067] Furthermore, a heating element 6 and a temperature sensor 52 are installed inside the water tank 1. The heating element 6, located inside the water tank, can be a heating plate, heating tube, heating rod, or other similar device to heat the liquid. The temperature sensor 52 is located on the water tank 1 and is used to detect the temperature inside the water tank 1.

[0068] The processor is also connected to the heating element 6 and is used to control the start and stop of the heating element 6. When the heating element 6 is turned on, it heats the liquid in the water tank 1.

[0069] The processor is connected to temperature sensor 52 to obtain the water tank temperature detected by temperature sensor 52.

[0070] Specifically, the temperature sensor 52 can be a waterproof DS18B20 temperature sensor. The DS18B20 temperature sensor has three pins: data line (DQ), power line (VDD), and ground line (GND). The data line of the DS18B20 sensor is connected to the GPIO pin of the Jetson Xavier module, the power line is connected to the 3.3V pin of the Jetson Xavier module, and the ground line is connected to the ground pin of the Jetson Xavier module.

[0071] Heating element 6 is connected to the GPIO pin of the Jetson Xavier module via a relay. The Jetson Xavier module controls the start and stop of heating element 6 via the relay based on the temperature information collected by temperature sensor 52. Heating element 6 heats the liquid in water tank 1 to 50℃-80℃, and then sprays it out through spray gun 2. Hot water within this range can effectively dissolve and adsorb pollutants in the air.

[0072] Furthermore, a water flow sensor 53 is used, installed on the pipeline connected to the water tank inlet 11, to collect liquid flow rate. The processor is also connected to the water flow sensor 53 to acquire the liquid flow rate detected by the water flow sensor.

[0073] Specifically, the water flow sensor 53 can be a PF3WB / C / S / R digital water flow sensor. The Jetson Xavier module connects to the water flow sensor 53 via a USB 3.0 interface, an M12 to USB adapter, and an M12 connector. The water flow sensor 53 corresponds to an IO-Link interface. The water flow sensor 53 is installed on a water source or pipe to measure the water flow velocity and calculate the amount of water flowing through the pipe. The water flow velocity is measured in liters or cubic meters per hour. The method of calculating the water volume is existing technology and will not be elaborated here. The water flow sensor 53 can be used to monitor leaks in water pipes or equipment. By monitoring the water flow in real time, leaks can be detected promptly, and repair measures can be taken to avoid wasting water resources and causing equipment damage.

[0074] Based on the above technical solution, the number of chemical reagent kits can be one or more. When more than two are used, each chemical reagent kit can contain the same chemical substance or different chemical substances.

[0075] This embodiment provides an implementation method: the chemical reagent kit includes a first reagent kit 41 and a second reagent kit 42, the first reagent kit 41 is used to contain a calcium and magnesium salt mixture, and the second reagent kit 42 is used to contain sodium chloride.

[0076] First reagent kit 41 (i.e.: Figure 3 The chemical reagent kit 01 is used to hold a calcium and magnesium salt mixture. The first reagent kit 41 is connected to the GPIO pin of the Jetson Xavier module via a relay switch. When the relay coil is energized or de-energized, the corresponding contact actuates to open the first reagent kit 41, releasing the calcium and magnesium salt mixture inside into the water tank 1. When the relay coil is energized or de-energized, the corresponding contact actuates to close the first reagent kit 41.

[0077] Specifically, the Jetson Xavier module controls the switching state of the relay via GPIO pins, thereby controlling the opening and closing of the first reagent kit 41. Because the calcium magnesium salt solution has good hygroscopicity and adhesion, it can quickly absorb moisture from the air, forming hydrates or hydrated crystals. This helps to moisten dust particles, causing them to adhere to the solution and reducing the movement and diffusion of dust particles in the air, thus effectively controlling dust.

[0078] Figure 3The telescopic structure 01 serves as a reagent kit opening mechanism and is connected to the Jetson Xavier module via a PCIe interface. The Jetson Xavier module sends pop-out or retraction commands to the telescopic structure 01 via the PCIe interface to control the pop-out and retraction of the telescopic structure 01. During the pop-out process, it drives the lid of the reagent kit to open. For example, the telescopic mechanism 01 can be translated by an electromagnet to drive the lid of the first reagent kit 41 to open or close.

[0079] Second reagent kit 42 (i.e.: Figure 3 The chemical reagent kit 02 is used to hold sodium chloride. The second reagent kit 42 is connected to the GPIO pin of the Jetson Xavier module via a relay switch. When the relay coil is energized or de-energized, the corresponding contact actuates to open the second reagent kit 42, releasing the sodium chloride inside into the water tank 1. When the relay coil is energized or de-energized, the corresponding contact actuates to close the second reagent kit 42.

[0080] While sprinkling water can temporarily moisten the ground, it evaporates quickly, losing its binding force on dust and causing it to fly again. Compared to sprinkling water, the moist layer formed by sodium chloride solution on the ground can more persistently fix dust particles, reducing the likelihood of dust flying and re-entraining, and has stronger durability.

[0081] Figure 3 The telescopic structure 02 serves as a reagent kit opening mechanism and is connected to the Jetson Xavier module via a PCIe interface. The Jetson Xavier module sends pop-out or retraction commands to the telescopic structure 02 via the PCIe interface to control the pop-out and retraction of the telescopic structure 02. During the pop-out process, it drives the lid of the reagent kit to open. For example, the telescopic structure 02 can be translated by an electromagnet to drive the lid of the second reagent kit 42 to open or close.

[0082] Furthermore, a display screen is used to show the water tank capacity, water output, location information, and the type of chemical reagents added to the water tank of the dust suppression truck. Older sprinkler trucks lack water level displays, leading to insufficient water supply and affecting vehicle utilization. The technical solution provided in this embodiment solves this problem. Specifically, the display can be an HDMI screen, connected to the HDMI interface of the Jetson Xavier module, to output video signals.

[0083] Furthermore, a button unit is used to connect to the processor, specifically as follows: Figure 3The system button unit is connected to the Jetson Xavier module via a GPIO interface, providing system reset and formatting button functions. When the user presses the reset button, the system resets; when the user presses the formatting button, the system restores factory settings.

[0084] Furthermore, storage units are connected to the processor, specifically as follows: Figure 3 The SSD solid-state storage module is connected to the M.2 Key M interface of the Jetson Xavier module. The M.2 Key M interface is formed through the UPHY(x4) bus to expand the module's data storage capacity and storage speed.

[0085] Furthermore, a positioning module is employed, connected to the processor, to communicate with satellites and obtain the current location of the dust suppression equipment. Specifically, a dual-frequency GPS module, such as the SKG8212, is used, with a positioning accuracy of approximately 1.5 meters. The Jetson Xavier module connects to the SKG8212 via a UART interface. The SKG8212 module has an input voltage VCC range of 3.0V to 3.6V, a power consumption of 41mA (3.3V), and a power consumption of 22μA in sleep mode. The SKG8212 module uses a UART interface, providing full-duplex, asynchronous serial communication with a baud rate up to 6Mbps and a default baud rate of 115200bps. It supports 5 / 6 / 7 / 8-bit data, and even, odd, or no parity. It supports data transmission and firmware upgrades, and the input and output signal types are LVTTL level.

[0086] Furthermore, an audio playback device is used, connected to the Jetson Xavier module via an I2S interface. After the spraying task is completed, the Jetson Xavier module controls the audio playback device to broadcast the task completion status, allowing the dust suppression truck driver to clearly understand the completion status and promptly proceed with the next task.

[0087] Furthermore, a communication interface module is employed, which is connected to the processor. This communication interface module is also used for external device communication connections, enabling data transfer between the processor and external devices.

[0088] One implementation includes a communication interface module comprising a mobile phone card slot for inserting a mobile phone card and communicating with external devices via a mobile network. Specifically, the mobile phone card slot can accommodate a mobile phone card, enabling the Jetson Xavier module to communicate with 3G, 4G, or 5G mobile networks based on the mobile phone card. This allows the driver of the dust suppression vehicle to control the dust suppression equipment via a mobile phone, or the cloud (server) to remotely control the dust suppression equipment via a mobile communication network.

[0089] Another implementation method includes a communication interface module comprising a vehicle wireless communication board that can be plugged into a card slot for communication with external devices. The vehicle wireless communication board is a V2X communication board, used to connect to a V2X wireless communication system. Vehicle-to-everything (V2X) technology is the technology used for vehicle-to-everything communication.

[0090] Open-pit mine unmanned driving systems typically have a large number of devices and sensors that need to communicate with each other and collect data. V2X enables local communication and data transmission between devices, while mobile communication networks can connect devices to remote servers, enabling remote monitoring and management of data. Especially when dust suppression vehicles cannot communicate directly with the cloud, the cloud can send control signals to the dust suppression equipment via broadcast signals among the mining trucks, preventing intelligent devices from losing connection and improving reliability.

[0091] Based on the above technical solution, this embodiment also provides a dust suppression vehicle, including: a vehicle body 7 and a dust suppression device installed on the vehicle body 7. Figure 1 The image only shows the water tank 1 and spray gun 2 installed on the vehicle body 7; the other components can be installed on the vehicle body as needed.

[0092] The dust suppression vehicle provided in this embodiment has the same technical effect as the dust suppression equipment described above.
