[0020] like Figure 1 As shown, this embodiment provides a fire hose with a signal cable, including a hose body 6 and male connectors 2 and water guns 5 respectively located at its two ends.

[0021] like Figure 2 As shown, the male connector 2 has an embedded annular permanent magnet array, and the circumferential array on the end face of the male connector 2 has multiple magnetic flanges 26, which are used to connect to the female connector of the water pipe by magnetic attraction.

[0022] This embodiment focuses on the structure of the male connector 2 and the hose body 6. The robot dog and female hose connector in a magnetic self-locking automatic fire hose docking system are not the focus of this embodiment, but for clarity of understanding of the structure of the male connector 2 and the hose body 6, the structure of the robot dog, female hose connector, male connector 2, and hose body 6 will be described in detail below:

[0023] The water hose body 6 is wound on the robot dog, and the robot dog is provided with a multi-modal sensor system including a laser radar module, a radio frequency signal receiving module and a visual recognition module. The laser radar module is used to construct a three-dimensional map of the floor and to locate the position of the fire hydrant in real time. The radio frequency signal receiving module is used to receive the radio frequency signal emitted by the water pipe female head, and to accurately locate the position of the water pipe female head according to the radio frequency signal strength and time difference algorithm, so that the male head 2 accurately docks with the water pipe female head. In addition, a servo motor can be provided on the robot dog, which is connected to the male head 2 and is used to adjust the posture of the male head 2.

[0024] The outer wall of the water hose body 6 is provided with a signal cable which is wound / unwound synchronously with the water hose body 6. One end of the signal cable is connected to the robot dog control module through a waterproof joint, and the other end of the signal cable is used to connect the electromagnetic valve control module at the water pipe female head when the male head 2 docks with the water pipe female head, so as to ensure the continuity of signal transmission. A plurality of wires are arranged in the signal cable, which are respectively used to transmit power, control signals and state feedback signals. The outer layer of the signal cable is made of waterproof and flame-retardant material, such as TPU, and the inside of the signal cable is reinforced with anti-tension fibers, so as to ensure that the signal cable is not broken when the water hose body 6 is unwound. If the signal cable transmission is interrupted, the robot dog can also switch to wireless signal for emergency control.

[0025] The robot dog is provided with a built-in tension sensor and a length sensor. The tension sensor is used to monitor the stretching state of the signal cable in real time, and the length sensor is used to monitor the unwound length of the water hose body 6. When the robot dog control module receives the following two signals: the signal that the unwound length of the water hose body 6 monitored by the length sensor reaches the preset length threshold, and the signal that the stretching tension of the signal cable monitored by the tension sensor is normal, the robot dog control module determines that the water hose body 6 is unwound normally. After the water hose body 6 is unwound normally, the robot dog control module is used to generate a control signal and send it to the electromagnetic valve control module. The electromagnetic valve control module is used to trigger the electromagnetic valve at the water pipe female head to be powered on, so that the valve is opened, and the water flows into the water hose body 6. Then, the electromagnetic valve control module sends a state feedback signal to the robot dog control module, so as to ensure that the fire extinguishing process is started normally.

[0026] If the stretching tension of the signal cable is too loose or too tight, or the unwound length of the water hose body 6 does not match the preset length threshold, the robot dog control module is used to trigger an alarm to alarm, and to trigger a backup fire extinguishing scheme, such as remote manual intervention.

[0027] The water pipe female head is provided with a radio frequency transmitting module, which is used to emit a radio frequency signal to the robot dog.

[0028] As Figure 3As shown, the end face of the water pipe female has a circumferential array of multiple positioning grooves 13. One end of the positioning groove 13 is connected to a magnetic groove 14, and the groove depth at this end of the positioning groove 13 is deeper than the groove depth at the other end. The outer wall of the water pipe female is provided with an annular latch groove 15, and an electromagnet ring 16 is provided in the latch groove 15.

[0029] Both the female and male connectors 2 are embedded with a ring-shaped permanent magnet array with matching polarity. The ring-shaped permanent magnet array can trigger strong magnetic adsorption when the distance is ≤3cm, thereby enabling the female and male connectors 2 to connect quickly and effectively.

[0030] like Figure 4 As shown, the male connector 2 includes an inner ring 21, an outer ring 22, and multiple latches 23. The outer diameter of the inner ring 21 is the same as that of the outer ring 22, but the inner diameter of the inner ring 21 is smaller than that of the outer ring 22. Multiple magnetic flanges 26 are arranged in a circumferential array on the end face of the inner ring 21. The magnetic flanges 26 are used to match the corresponding magnetic grooves 14. The inner wall of the outer ring 22 has multiple mounting slots 24 arranged in a circumferential array. The latches 23 are connected to the mounting slots 24 by springs 25. When the male connector 2 is connected to the female connector and the magnetic flanges 26 match the corresponding magnetic grooves 14, the electromagnet ring 16 is used to magnetically attract the latches 23, so that the latches 23 are embedded in the latch grooves 15. Thus, the male connector 2 and the female connector are locked together by magnetic attraction and mechanical limiting, as shown in the figure. Figure 5 , Figure 6 As shown.

[0031] To improve the sealing performance of the male connector 2 and the female water pipe connector, such as Figure 6 As shown, a sealing ring 27 is provided at the inner right angle formed by the inner ring 21 and the outer ring 22.

[0032] During use, the robot dog autonomously locates the fire hydrant box. The radio frequency signal emitted by the female water pipe connector guides the male connector 2 on the robot dog to automatically magnetically connect with the female water pipe connector (similar to the charging interface of a robot vacuum cleaner). The electromagnet ring 16 magnetically attracts the latch 23, so that the latch 23 is embedded in the latch groove 15, thereby locking the male connector 2 and the female water pipe connector through both magnetic attraction and mechanical limiting. When the robot dog moves to the fire extinguishing point, the main body of the water hose 6 automatically unfolds during the movement. After the main body of the water hose 6 is normally unfolded, the robot dog control module generates a control signal and sends it to the solenoid valve control module. The solenoid valve control module triggers the solenoid valve at the female water pipe connector to be energized, the valve opens, and water flows into the main body of the water hose 6. Then, the solenoid valve control module sends a status feedback signal to the robot dog control module to ensure that the fire extinguishing process starts normally.

Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
