[0018] When a hydraulically driven self-oscillating device fails, the fire monitor device cannot be driven horizontally to swing horizontally, thus failing to provide targeted protection for the ship lock and achieving true automatic water sprinkler fire extinguishing and cooling. For example, when the hydraulic pump of the hydraulically driven device leaks, the hydraulically driven self-oscillating device cannot reach the preset swing angle and always operates at a low speed and a small angle range. This embodiment provides a water-electric dual-drive fire monitor device suitable for ship locks. The fire monitor device suitable for water-electric dual-drive ship locks mainly comprises a fixed fire monitor 1, a hydraulic self-oscillating device 2, and a solar panel 3.
[0019] Specifically, such as Figure 1 As shown, the fixed fire monitor 1 is fixedly installed on the outlet flange 10 of the hydraulic self-swinging device 2; Figure 2 As shown, the fixed fire monitor 1, the hydraulic self-swinging device 2 and the solar panel 3, the rechargeable battery box 4, the drive controller 5, and the water supply pipe 6 are all installed at the opening of the wall 7. The fixed fire monitor 1 is a stainless steel tubular structure. One end of the fixed fire monitor 1 is provided with a horizontal motor and a column mist motor, and one end thereof is fixedly mounted on the outlet flange 10 of the hydraulic self-swinging device 2. The hydraulic self-swinging device 2 is fixedly mounted on the inlet flange 8 interface of the water supply pipe 6. It includes a pressure sensor installed in the fire water supply pipeline, and a Hall proximity sensor that cooperates with a strong magnet to generate a potential difference.
[0020] like Figure 3 As shown, the hydraulic self-oscillating device 2 consists of an inlet flange 8, an outlet flange 10, a Hall effect circuit 11, a linkage rod 9, and a water wheel component. The inlet and outlet flanges 8 and 10 are fastened together to form a tubular structure. The Hall effect circuit 11 is installed inside the housing and is a HL-20N1 product from Bontos. The power is supplied by the drive controller 5. The water wheel component includes a pressure sensor installed in the pipeline and a Hall effect proximity sensor that generates a potential difference with the Hall effect circuit 11. The pressure sensor is an SPM03BY6N2 product from Enbon, and the Hall effect proximity sensor is an HL-20N1 product from Bontos.
[0021] like Figure 4 As shown, the pressure sensor is connected to the Hall circuit 11 through the I / O interface, and the Hall proximity sensor is connected to the Hall circuit 11 through the ADC interface. The pressure sensor and the Hall proximity sensor constitute the acquisition part of the Hall circuit 11. The pressure sensor is used to collect the pressure value in the water supply pipeline of the fire pump motor. The Hall proximity sensor cooperates with a strong magnet to produce a Hall effect.
[0022] The working principle of the fire monitor device suitable for water and electricity dual drive of ship lock is as follows:
[0023] A Hall effect sensor is a magnetic field sensor based on the Hall effect. A constant current I passes through a Hall effect semiconductor chip in a magnetic field, traveling from A to B. Due to the Lorentz force, the electron flow I deflects to one side as it passes through the Hall effect semiconductor, generating a potential difference in the direction CD across the chip. This is known as the Hall voltage. The Hall voltage varies with magnetic field strength: stronger fields increase the voltage, while weaker fields decrease it. While the Hall voltage is very small, typically only a few millivolts, it can be amplified by the amplifier in the integrated circuit to produce a strong output signal. Hall effect switch devices offer contactless, wear-free operation, clear output waveforms, zero jitter or bounce, and high position repeatability (down to the micron level). Furthermore, Hall effect devices, incorporating various compensation and protection measures, have a wide operating temperature range (from -55°C to 150°C), making this sensor technology widely used.
[0024] The Hall effect integrated circuit (HIT) performs a sensing function, requiring mechanical means to alter the magnetic induction intensity. A rotating impeller is typically used as a switch to control the magnetic flux. When the impeller blades are within the air gap between the magnet and the Hall effect integrated circuit (HIT), the magnetic field deviates from the integrated circuit, and the Hall effect voltage disappears. Thus, changes in the Hall effect integrated circuit's output voltage can indicate a specific position of the impeller drive shaft. Based on this operating principle, this embodiment utilizes a water wheel that rotates circumferentially within the fire pump motor via a magnetic induction bracket along with the shaft. Rotation of the water wheel's shaft represents rotation of the water wheel's impeller blades. When a Hall effect proximity sensor and a pressure sensor are employed, the Hall effect proximity sensor is installed within the fixed fire monitor 1, and the pressure sensor is installed in the fire water supply pipeline. The voltage generated by the Hall effect proximity sensor varies with changes in magnetic field intensity.
[0025] Specifically, the Hall voltage formed by the Hall proximity sensor and the Hall circuit 11 changes from strong to weak and then to the disappearance of the voltage, and from the disappearance of the voltage to weak and then to strong, which is one circle of the water wheel. When the water supply pressure of the fire water supply pipeline increases, the frequency of change of the above-mentioned Hall voltage becomes faster, which means that the mechanical performance of the fire pump motor is normal. Otherwise, it means that there is a problem with the mechanical performance of the fire pump motor. The MCU on the Hall circuit 11 records the above-mentioned Hall voltage changes and water supply pressure changes, stores the data in the EEPROM erasable programmable read-only memory, and transmits it to the background service terminal through the NB-IoT communication module. The operation and maintenance personnel can intuitively understand whether there is a mechanical performance failure of the fire pump motor installed in unmanned places such as highway tunnels through the background service terminal.
[0026] Furthermore, as the preferred technical solution of this embodiment:
[0027] like Figure 1As shown, one end of the fixed fire monitor 1 is installed on the outlet flange 10 of the hydraulic self-swinging device 2, and the solar panel 3 is installed on the upper side of the rechargeable battery box 4; the solar panel 3 cooperates with the rechargeable battery box 4 to power the drive controller, and the fixed fire monitor 1 determines whether the hydraulic drive needs to be converted into electric drive through the Hall circuit 11 to ensure that the fixed fire monitor 1 rotates within a controllable range inside the hole in the wall 7 through the hydraulic self-swinging device 2.
[0028] Furthermore, as the preferred technical solution of this embodiment:
[0029] In terms of pressure sensors and Hall proximity sensors, such as Figure 4 As shown, a pressure sensor and a Hall proximity sensor can be used; a Hall proximity sensor is arranged on the outer cover of the fire pump motor along the circumferential rotation path of the strong magnet, so as to more accurately indicate that the shaft of the fire pump motor has rotated to a certain position; multiple pressure sensors are installed at different positions of the water supply pipeline to accurately detect the water supply pressure of the fire water supply pipeline.
