[0018] Figure 2 This is a schematic structural diagram of a pure electric hydrogen fuel cell sprinkler device in another embodiment of the present application. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] In this application, a methanol hydrogen production system is integrated into the sprinkler to achieve self-supply of hydrogen. At the same time, a hydrogen fuel cell is used to drive the sprinkler, thereby solving problems such as high hydrogen storage and transportation costs and a limited number of hydrogen refueling stations, and improving the environmental performance and endurance of the sprinkler.

[0021] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] In an exemplary embodiment, Figure 1 As shown, a pure electric hydrogen fuel cell sprinkler device is provided, including a main controller, a hydrogen production system, a hydrogen fuel cell system, a sprinkler system and a waste heat recovery system.

[0023] The hydrogen production system is used to: receive the hydrogen production instruction issued by the main controller; prepare hydrogen according to the hydrogen production instruction, and transport the hydrogen to the hydrogen fuel cell system. The hydrogen production system includes a hydrogen production controller, a raw material storage tank, a hydrogen production reactor, a gas storage tank and a purification component; in one application, methanol is stored in the raw material storage tank, so that methanol can be used to produce hydrogen.

[0024] Specifically, the hydrogen production controller is used to: receive the hydrogen production instruction issued by the main controller, and send the hydrogen production instruction to the hydrogen production reactor. The raw material storage tank, the hydrogen production reactor, the gas storage tank and the purification component are connected in sequence. The hydrogen production reactor is used to: construct a hydrogen production environment condition based on the hydrogen production instruction; under the hydrogen production environment condition, obtain the raw material from the raw material storage tank and perform a chemical reaction to produce a mixed gas containing hydrogen. The gas storage tank is used to: store the mixed gas containing hydrogen. The purification component is used to: filter the mixed gas containing hydrogen to obtain hydrogen; and transport the hydrogen to the hydrogen fuel cell system.

[0025] In a specific application, after the hydrogen production controller receives the hydrogen production instruction, the methanol cracking hydrogen production machine controller (corresponding to the hydrogen production controller) controls the heating plate to heat. When the methanol cracking vaporization chamber is heated to the vaporization temperature, the methanol pump arranged on the pipeline between the raw material storage tank and the hydrogen production reactor is turned on, methanol is injected into the vaporization chamber, and the heating plate continues to heat to the temperature required for the reaction; at this time, the pressure of the vaporization chamber gradually increases, and the vaporized methanol enters the reaction chamber under the action of pressure to perform a cracking chemical reaction, and produces a mixed gas such as hydrogen and carbon monoxide under the action of the catalyst. The catalytic reaction is an endothermic reaction, and the heating plate is required to maintain the reaction temperature during the process. After the reaction, the mixed gas containing hydrogen flows into the heat exchanger in one direction, and at the same time, part of the heat energy enters the heat exchanger for heat exchange, thereby improving the utilization rate of heat energy. The mixed gas containing hydrogen enters the gas storage tank. Since what is stored is hydrogen, it can also be understood as a hydrogen storage tank. The mixed gas containing hydrogen is sent to the purification component through the hydrogen storage tank. In the purification component, the mixed gas containing hydrogen is filtered through adsorption technology and membrane separation technology to obtain high-purity hydrogen, which is then transported to the hydrogen fuel cell system through a pipeline.

[0026] In another specific application, taking the sprinkler device of the present application as a sprinkler truck as an example, the process of determining the hydrogen production instruction is as follows: When the sprinkler truck starts, the main controller determines the current battery power status according to the power indicator on the vehicle dashboard or the relevant electronic display screen; the current battery power status includes whether it is sufficient to support the vehicle start, that is, whether the power is sufficient. If the power is sufficient (such as green or full), it means that the sprinkler truck has enough power to start. If the power is low (such as yellow or red area), it may be necessary to charge the battery first to ensure a smooth start. As for when to charge, it is necessary for relevant technicians or drivers to choose. If the power is insufficient, the main controller sends a hydrogen production instruction to the hydrogen production system. Among them, the hydrogen production system is located at the rear of the front of the sprinkler truck.

[0027] The hydrogen fuel cell system is used to: chemically react the received hydrogen to generate electrical energy, thermal energy and water; the electrical energy is used as a driving energy source. The hydrogen fuel cell system includes a battery management system and a plurality of hydrogen fuel cell units.

[0028] Specifically, the battery management system is used to: monitor the status information of the plurality of hydrogen fuel cell units; perform energy distribution, balance management, thermal management, safety protection and fault diagnosis based on the status information of each hydrogen fuel cell unit, and determine the corresponding opening and closing instructions. The hydrogen fuel cell unit is used to: when the received opening and closing instructions indicate opening, chemically react the received hydrogen with oxygen to generate electricity, heat and water.

[0029] In a specific application, each hydrogen fuel cell unit contains key components such as electrolyte membrane, anode and cathode. Hydrogen is input to the anode through hydrogen storage tanks and purification components, and oxygen is sent to the cathode from the air through a compressor. Inside the hydrogen fuel cell unit, hydrogen and oxygen undergo electrochemical reactions to generate electricity, heat and water. Among them, the electrical energy is transmitted to the drive system through wires to drive the motor inside the motion execution system; the heat energy is processed through the waste heat recovery system; and the water enters the sprinkler system to participate in subsequent sprinkler operations.

[0030] In another specific application, the battery management system monitors the status of each hydrogen fuel cell unit in real time, optimizes energy distribution, and ensures safe and stable operation of the system. Specifically, real-time monitoring refers to: continuously monitoring the voltage, current, temperature and other key parameters of each hydrogen fuel cell unit to ensure that the battery operates within a safe working range; the above multiple key parameters can collect data through sensors to detect abnormal conditions in a timely manner. Energy distribution refers to: intelligently distributing battery energy according to vehicle operation requirements and battery status to optimize the vehicle's cruising range and performance. Balance management refers to: in order to prevent the inconsistency of single cells in the hydrogen fuel cell unit from causing performance degradation, the battery is balanced to ensure that the charge and discharge status and health status of each battery cell are consistent. Thermal management refers to: controlling the battery cooling and heating system to maintain the battery operating within the optimal temperature range to prevent overheating or overcooling from affecting battery performance and life. Safety protection refers to: once an abnormality is detected, such as overcharging, overdischarging, short circuit, overtemperature, etc., take immediate measures, such as disconnecting the battery from the vehicle, to prevent potential safety risks. Fault diagnosis refers to: supporting remote diagnosis and software updates to ensure that the hydrogen fuel cell system is always in the best condition. In addition, the battery management system also provides battery status information through communication with other vehicle systems. Taking the water sprinkler device of the present application as a water sprinkler truck as an example, the hydrogen fuel cell system is located at the rear of the front of the water sprinkler truck and is integrated with the hydrogen production system.

[0031] The watering system is used to: store water generated by the hydrogen fuel cell system; receive a watering instruction issued by the main controller; and perform a watering operation according to the watering instruction. The watering system includes a watering controller, a water tank, a water pump, and a watering nozzle.

[0032] Specifically, the water tank is used to store water generated by the hydrogen fuel cell system and pre-stored water. The sprinkler controller is used to receive a sprinkler instruction issued by the main controller; turn on the water pump and the sprinkler head according to the sprinkler instruction, and send a water volume instruction to the sprinkler head; the water volume instruction includes a sprinkler volume and a sprinkler range to meet different sprinkler requirements. The water pump is used to pump water from the water tank and pressurize it to the sprinkler head. The sprinkler head is used to perform a sprinkler operation according to the water volume instruction.

[0033] In a specific application, the pure electric hydrogen fuel cell sprinkler device also includes a sensor system; the sensor system is used to: detect the surrounding road conditions and the surrounding environmental conditions, and send the surrounding road conditions and the surrounding environmental conditions to the main controller; the main controller is used to: determine the sprinkler instruction based on the surrounding road conditions and the surrounding environmental conditions. Taking the sprinkler device of this application as a sprinkler truck as an example, the sensor system includes a temperature sensor, a humidity sensor, and a radar, and they are all set on the sprinkler truck; the sprinkler system is set on the top, rear or bottom of the sprinkler truck.

[0034] When determining the watering instruction, the main controller can make the determination according to the following principles: when the surrounding road conditions indicate that there are pedestrians around (which can be detected by radar), the sprinkler head is controlled to close or reduce the water spraying amount; when the surrounding road conditions indicate that the pedestrians are too far away from the sprinkler truck and the sprinkler truck is spraying at a long distance, the water spraying amount is reduced to prevent the pedestrians from being drenched. When the surrounding environment conditions indicate that the road surface temperature is too high (which can be detected by a temperature sensor), the sprinkler head is set to the spray mode, so that the distance is up to several meters; when the surrounding environment conditions indicate that the temperature is too low, the sprinkler head is set to the spray mode, so that the nozzle sprays water on the road surface in a shower-like manner.

[0035] The waste heat recovery system is used to store the heat energy generated by the hydrogen fuel cell system and transfer the heat energy to the hydrogen production system. Specifically, the heat energy generated by the hydrogen fuel cell system enters the hydrogen production reactor in the hydrogen production system through a heat exchanger to improve the reaction efficiency.

[0036] In another exemplary embodiment, Figure 2 As shown, the pure electric hydrogen fuel cell sprinkler device also includes a drive system and a motion execution system. The drive system is used to obtain the electrical energy generated by the hydrogen fuel cell system and convert the electrical energy into mechanical energy to drive the motion execution system to move.

[0037] Specifically, the drive system includes a drive controller, an electric motor and a transmission component; the drive controller is used to: monitor the status of the electric motor, the transmission component and the motion execution system, and determine the corresponding drive control instructions; the electric motor is used to: convert the electrical energy into mechanical energy based on the drive control instructions; and transmit the mechanical energy to the motion execution system via the transmission component to achieve driving. Taking the sprinkler device of the present application as a sprinkler truck as an example, the electric drive system is located at the bottom of the sprinkler truck or in the motor compartment. The motor receives electrical energy from the hydrogen fuel cell system, adjusts the current and voltage through the controller, and converts the electrical energy into mechanical energy to drive the sprinkler truck to travel and sprinkle water; the transmission device is responsible for transmitting the power of the motor to the wheels or other actuators in the motion execution system.

[0038] The waste heat recovery system is also used to store the kinetic heat energy generated by the motion execution system during the motion process, and transfer the kinetic heat energy to the hydrogen production system. Taking the sprinkler device of the present application as a sprinkler truck as an example, the waste heat generated during the driving process of the sprinkler truck is sent to the hydrogen production system through a heat exchanger to provide additional heat energy, further improving the efficiency of the methanol hydrogen production reaction, and also promoting the conversion rate of methanol, thereby reducing energy waste and further improving the overall performance of the sprinkler truck.

[0039] Based on the same inventive concept, the embodiment of the present application also provides a pure electric hydrogen fuel cell water sprinkling method applied to the above-mentioned pure electric hydrogen fuel cell water sprinkling device. The implementation scheme for solving the problem provided by the method is similar to the implementation scheme recorded in the above-mentioned device, so the specific limitations in the embodiments provided below can be referred to the limitations above, and will not be repeated here.

[0041] Step 200, the hydrogen gas received is chemically reacted by the hydrogen fuel cell system to generate electrical energy, thermal energy and water; the electrical energy is used as a driving energy source.

[0042] Step 300, storing water generated by the hydrogen fuel cell system through a sprinkler system, receiving a sprinkler instruction issued by the main controller and performing a sprinkler operation according to the sprinkler instruction.

[0043] Step 400: store the heat energy generated by the hydrogen fuel cell system through a waste heat recovery system, and transfer the heat energy to the hydrogen production system.
