A limiting mechanism for limiting and fixing the second sealing gasket is connected to the connector. A water pipe is threaded onto the connector, and the sealing gasket is fitted onto the connection between the connector and the water pipe. This technical solution also suffers from the aforementioned technical problems. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6 A heavy-duty high-lift forest fire pump includes a fully protected frame consisting of two square frames 11, two top beams 12, two bottom beams 3, and a mounting box 14. The front and rear ends of the two top beams 12 are fixedly welded to the two square frames 11, respectively. The two bottom beams 13 are located below the two top beams 12, and their ends are also fixedly welded to the square frames 11. The mounting box 14 is a box with an open front and rear top. The bottom beams 13 are divided into left and right sides. The bottom of the left bottom beam 13 and the bottom of the mounting box 14 are both fixedly equipped with casters 18. The casters 18 are specifically existing braked casters, which are omnidirectional casters and also have a braking mechanism. Two bolts 16 pass through each square frame 11. One side of the bolt 16 surface is smooth, and the other side is threaded. A nut 15 is threaded onto the surface to prevent the bolt 16 from detaching from the square frame 11. The bolt 16 can also rotate. A connecting bracket 17 is fitted onto the smooth surface of the bolt 16. The connecting bracket 17 can rotate on the surface of the bolt 16. The connecting bracket 17 is mainly a sleeve, and two fins are welded onto the sleeve. The openings on the fins are adapted to the smooth part of the bolt 16 surface. A handle 17 is fixedly welded onto the inner wall of the sleeve. A soft sleeve 23 made of rubber is movably fitted onto the surface of the handle 17. When the handle 17 is lifted, after rotating 90 degrees, the top of the handle 17 is exactly against the side of the square frame 11, so that the handle 18 can no longer be lifted upwards. The handle 18 can withstand the lifting force of the worker. The cooperation of the above-mentioned structures realizes a frame that is easy to lift and push.

[0016] The pumping operation requires a power source and a pump body. The power source, including an engine 25, is housed within the frame of this technical solution. A gearbox 4 is mounted on the side of the engine 25. The engine 25 is a four-stroke 25.8KW gasoline engine, which is rationally designed and provides stable power. An oil filter 5 is connected to the side of the engine 25. A starter motor assembly 6 is connected to the side of the engine 25 away from the oil filter 5. Spark plugs 7 and an oil dipstick 8 are located on the cylinder block of the engine 25. An air filter 9 is located on top of the engine 25. A lifting lug 10 is fixedly connected to the engine 25. An electromagnetic switch 24 is mounted on the side of the engine 25. The motor 25 is connected to the reducer 2 via the gearbox 4. The drive shaft of the reducer 2 is connected to the diaphragm pump 1. The diaphragm pump 1 is equipped with an inlet pipe and an outlet pipe. An accumulator 19 is fixedly installed inside the mounting box 14. An external oil tank is also installed inside the mounting box 14, located behind the diaphragm pump 1, to increase oil capacity and working time. The external oil tank has a volume of 25L. The accumulator 19 is connected to the diaphragm pump 1 and is equipped to absorb circuit vibration waves and reduce vibration. The diaphragm pump 1 is made of precision cast aluminum alloy with a tensile strength of 300MPa and a high pressure resistance of over 4MPa. It undergoes CNC milling and turning precision machining followed by anodizing. The pump body is formed in one piece using a high-strength aluminum alloy die-casting process. The pump casing and pump body are made of high-strength corrosion-resistant aluminum alloy casting. The water pump undergoes anodizing treatment, and the water pump and engine surfaces have an anti-corrosion coating. To ensure the service life of the diaphragm pump 1, the diaphragm pump 1 should be regularly lubricated or replaced with suitable lubricating oil (10W-40 grade recommended). The reducer 2 is made of alloy steel precision casting and CNC precision machining. It adopts the planetary transmission principle, has a compact structure, small backlash, and high precision, and is suitable for applications with high requirements for size and torque. Forest fire pumps are used outdoors, and during forest fires, there are easily falling trees, etc. This technical solution addresses this issue in the frame design. A shield 21 is installed above the pump to protect it. Four rods 22 are fixedly welded to the bottom of the shield 21. Two slots 20 are opened at the top of each square frame 11. The slots 20 are adapted to the rods 22. The technical solution is shown in the exploded diagram shown in the figure for intuitive observation. When in use, the rods 22 are inserted into the slots 20. The shield 21 will protect the top of the entire fire pump, preventing foreign objects from damaging the power source and diaphragm pump 1 and other structures. In addition, the shield 21 can also provide good protection in light rain. When placed outdoors, the shield 21 can also block sunlight and rain.

[0017] The entire forest fire pump has an output power of 35HP (25.8KW), an output speed of 3600r / min, a power displacement of 999cc, a working flow rate of 160.17L / min, a maximum flow rate of 180.04L / min, a maximum pressure of 8.01MPa, a maximum head of 801m, a range of 31.5m, a self-priming suction depth of 7m, and inlet and outlet diameters of 40mm.

[0018] In use, the water suction pipe and water spray pipe are connected to the inlet and outlet pipes of the diaphragm pump 1, respectively. When the engine 25 is working, the output shaft of the engine 25 transmits power through the gearbox 4 and the reducer 2, driving the diaphragm pump 1 to work. This allows water to be pumped for fire extinguishing. The set of the moving wheels 18 makes the entire water pump easy and quick to move. In some places where it cannot be moved directly, the staff can directly turn the handle 3 to the horizontal position. The four handles 3 allow multiple people to lift the entire water pump directly. The soft sleeve 23 is soft and can protect the lifting personnel well. The insertion rod 22 is inserted into the slot 20. The cover plate 21 covers the entire water pump, which can serve as a protection purpose. In addition, the cover plate 21 is also easy to remove.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
