Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: See Figures 1 to 4 According to an embodiment of the utility model, a technical solution is provided: a water supply pump device for a forest fire fighting system based on a fire truck, used in conjunction with a fire truck 1 having a carriage 2, the water supply pump device comprises a water supply tank 7, a lifting platform 6 and a water spraying drone 3 having a water storage tank 4, the water supply tank 7 is placed in the carriage 2, the lifting platform 6 is located above the water supply tank 7, and the carriage 2 has a window 5 for the water spraying drone 3 to pass through, and the lifting platform 6 is provided with a liquid supply end, the liquid supply end comprises a funnel-shaped nozzle 8, and a nozzle 8 connected to the bottom of the nozzle 8. A liquid supply pipe 9 fixed to the lifting platform 6, an electromagnet 10 arranged at the bottom of the nozzle 8 and sleeved on the outside of the liquid supply pipe 9, and a liquid supply pump 11 connected between the water supply tank 7 and the liquid supply pipe 9, the water inlet end of the liquid supply pump 11 is connected to the water supply tank 7 through a water inlet pipe 23, and a liquid receiving end is provided on the water storage tank 4 of the water spraying drone 3, the liquid receiving end includes a liquid inlet hose 12 connected to the water storage tank 4, an annular electromagnet 13 arranged at the connection position of the liquid inlet hose 12 and the water storage tank 4, and an iron ring 14 sleeved on the free end of the liquid inlet hose 12.

[0022] The water supply pump device for the forest fire fighting system based on the fire truck 1 with the above structure is adopted. When the water spraying drone 3 is parked on the lifting platform 6, the free end of the liquid inlet hose 12 at the bottom of the water storage tank 4 of the water spraying drone 3 can be connected with the nozzle 8 at the liquid supply end. At this time, by controlling the electromagnet 10 to be energized, the free end of the iron ring 14 of the liquid inlet hose 12 is magnetically fixed in the nozzle 8, the annular electromagnet 13 is turned on and the liquid supply pump 11 is started, so that the water in the water supply tank 7 can be pumped into the water storage tank 4 of the water spraying drone 3, thereby achieving the purpose of replenishing water for the water storage tank 4 of the water spraying drone 3. After the water replenishment is completed, the power supply of the electromagnet 10 is disconnected, the annular electromagnet 13 and the liquid supply pump 11 are turned off, and the water spraying drone 3 can take off for water spraying operations. When the water volume in the water storage tank 4 of the water spraying drone 3 is insufficient, the water spraying drone 3 can fall back to the lifting platform 6 again and repeat the above operation to take water again. In this way, the water spraying drone 3 does not need to carry a water pipe to connect to the ground, and its operation and movement are more flexible.

[0023] It should be noted that the opening and closing control of the electromagnet 10, the annular electromagnet 13 and the liquid supply pump 11 can be achieved by controlling the switch. In addition, the control of the lifting, spraying and flying of the water spraying drone 3 belongs to the existing technology and will not be repeated here.

[0024] In this embodiment, the window 5 is arranged at the top of the carriage 2, and the size of the window 5 is larger than the size of the lifting platform 6. Both sides of the bottom of the lifting platform 6 are connected to the inner bottom of the carriage 2 through electric push rods 15. When the water spraying drone 3 needs to be used, the lifting platform 6 can be pushed out from the window 5 on the top of the carriage 2 to the top of the carriage 2 through the electric push rods 15, which can facilitate the take-off and landing of the water spraying drone 3.

[0025] In this embodiment, slide rails 16 are provided on opposite sides of the window 5, and a cover plate 17 is slidably connected to the slide rails 16 along the length direction of the carriage 2, and the size of the cover plate 17 is larger than the size of the window 5. By providing an openable and closable cover plate 17 at the position of the window 5, the window 5 can be closed by using the cover plate 17 when the water spraying drone 3 is not in use or in rainy days, so as to prevent dust or rainwater from falling into the carriage 2 through the window 5.

[0026] In this embodiment, the lifting platform 6 includes a bottom plate 60 and two force plates 61 arranged on the top of the bottom plate 60. When the water spraying drone 3 is parked, the landing gear 22 at the bottom thereof is placed on the force plates 61. A pressure sensor 18 is installed between the force plates 61 and the bottom plate 60. The pressure sensor 18 is connected to the annular electromagnet 13, the liquid supply pump 11 and the electromagnet 10 through the controller. After arriving at the work site, the overall weight of the water spraying drone 3 parked on the lifting platform 6 can be monitored by the pressure sensor 18. When the water volume in the water storage tank 4 of the water spraying drone 3 is insufficient and the overall weight of the water spraying drone 3 is lower than the set value of the pressure sensor 18, the controller controls the annular electromagnet 13, the liquid supply pump 11 and the electromagnet 10 to start, thereby pumping the water in the water supply tank 7 into the water storage tank 4 until the overall weight of the water spraying drone 3 reaches the set value of the pressure sensor 18. The controller controls the annular electromagnet 13, the liquid supply pump 11 and the electromagnet 10 to close, thereby achieving the purpose of automatically replenishing water to the water spraying drone 3, making the water supply pump device more intelligent. It should be noted that the connection method between the pressure sensor 18, controller, annular electromagnet 13, liquid supply pump 11 and electromagnet 10 belongs to the existing technology, and the model selection of the pressure sensor 18, controller, annular electromagnet 13, liquid supply pump 11 and electromagnet 10 can be set according to actual conditions, which will not be repeated here.

[0027] In this embodiment, the rear part of the carriage 2 and its left and right sides are provided with side openings 19, and each side opening 19 is provided with a rolling door 20 that can be opened upward. By providing the side openings 19 and the rolling door 20 that can be closed at the side openings 19, when the water supply tank 7, the lifting platform 6 and the water spraying drone 3 in the carriage 2 need maintenance, they can be inspected and maintained by opening the rolling door 20, which improves the convenience of inspection and maintenance.

[0028] In this embodiment, a sealing gasket 21 is provided at the bottom of the nozzle 8, and when the liquid inlet hose 12 is inserted into the nozzle 8, the iron ring 14 abuts against the sealing gasket 21. When the electromagnet 10 is energized, the iron ring 14 at the end of the liquid inlet hose 12 will be firmly adsorbed in the nozzle 8, and the provision of the sealing ring can increase the sealing of the connection position between the liquid inlet hose 12 and the nozzle 8, ensuring that there is no water leakage during the water delivery process.

[0029] Working principle: When the amount of water in the water storage tank 4 of the water spraying drone 3 is insufficient, the water spraying drone 3 can be parked on the lifting platform 6, and the free end of the liquid inlet hose 12 at the bottom of the water storage tank 4 of the water spraying drone 3 can be connected with the nozzle 8 at the liquid supply end. At this time, by controlling the electromagnet 10 to be energized, the free end of the iron ring 14 of the liquid inlet hose 12 is magnetically fixed in the nozzle 8, the annular electromagnet 13 is turned on and the liquid supply pump 11 is started, so that the water in the water replenishment tank can be pumped into the water storage tank 4 of the water spraying drone 3, thereby achieving The purpose of replenishing water in the water tank 4 of the water spraying drone 3 is to disconnect the power supply of the electromagnet 10 after the water replenishment is completed, turn off the annular electromagnet 13 and the liquid supply pump 11, and the water spraying drone 3 can take off to perform water spraying operations. During the water spraying operation, when the water volume in the water tank 4 of the water spraying drone 3 is insufficient again, the water spraying drone 3 returns and falls back onto the lifting platform 6, and then repeats the above operation to take water again. In this way, since the water spraying drone 3 does not need to carry a water pipe to connect to the ground, the flexibility of its operation and movement can be ensured.
