The first telescopic rail 23 comprises a first sliding rail 231 and a first fixed rail 232, and the structure is shown in fig. 3. The first sliding rail 231 is in transmission connection with the first fixed rail 232. It should be noted that the first sliding rail 231 and the first fixed rail 232 may be in transmission connection through a pulley or a ball. The outer sleeve 215 is arranged on a first sliding rail 231 and the first fixed rail 232 is arranged on the vehicle body chassis 1.

The second telescopic rail 24 includes a second sliding rail 241 and a second fixed rail 242, and is configured as shown in fig. 3 and 4. The second sliding rail 241 is in transmission connection with the second fixed rail 242. It should be noted that, when the second sliding rail 241 and the second fixed rail 242 are in transmission connection through a pulley or a ball, the disposing of the outer sleeve 215 on the first sliding rail 231 specifically includes: the outer sleeve 215 is first disposed on the second sliding rail 241, and the second fixed rail 242 is then connected to the first sliding rail 231.

In this embodiment, the outer diameter of the first front inner tube is smaller than the inner diameter of the first rear inner tube, and the first front inner tube is disposed in the first rear inner tube when the telescopic water pipe assembly is contracted. Or: the outer diameter of the first rear inner sleeve is smaller than the inner diameter of the first front inner sleeve, and the first rear inner sleeve is arranged in the first front inner sleeve when the telescopic water pipe assembly contracts. The first front inner sleeve, the first rear inner sleeve and the rest of the sleeves are all accommodated in the outer sleeve, and the structure is shown in fig. 7, so that the length of the telescopic water pipe assembly after being accommodated can be reduced.

The piston rod 222 is controlled to move out of the cylinder 221 slowly, so that the second rear inner sleeve 217 can be driven to move out of the first rear inner sleeve 216; conversely, movement of the control piston rod 222 back into the cylinder 221 causes the second rear inner sleeve 217 to retract into the outer first rear inner sleeve 216.

In a preferred embodiment, the number of the telescopic mechanisms is two, one telescopic mechanism is used for driving the outer sleeve and the first rear inner sleeve to slide mutually, and the other telescopic mechanism is used for driving the first rear inner sleeve and the second rear inner sleeve to slide mutually. When the rest telescopic water pipes are inclined, the other telescopic water pipes can slide according to the gravity borne by the telescopic water pipes.

It should be noted that the telescopic water pipe assembly needs to be obliquely arranged when in use, and the water outlet end of the telescopic water pipe assembly is tilted upwards, so that the water inlet end of the telescopic water pipe assembly moves out from the water outlet end of the telescopic water pipe assembly and is inserted into a lake or a pond. At the moment, the first-stage telescopic water pipe at the water outlet end of the telescopic water pipe assembly does not slide, so that the telescopic water pipe assembly is conveniently connected with the connecting pipeline.

Specifically, the telescopic water pipe assembly is only provided with the outer sleeve, the first front inner sleeve and the first rear inner sleeve. The first front inner sleeve is the water outlet end of the telescopic water pipe assembly and is connected with the connecting pipeline. When the telescopic water pipe assembly enters a water taking state, the position of the first front inner sleeve pipe is kept still, the outer sleeve pipe moves downwards to be discharged, and the first rear inner sleeve pipe also moves downwards to be discharged.

One conduit is one end of the second water tube assembly, namely the water outlet end 71 of the second water tube assembly; the other conduit is the other end of the second water tube assembly, i.e., the water inlet end 72 of the second water tube assembly. One end of the second water pipe assembly is arranged on the chassis of the vehicle body, and the water inlet end 72 of the second water pipe assembly is arranged on the base. In this way, when the moving mechanism 14 moves the driving base 12 towards the direction away from the head of the chassis of the vehicle body, the water inlet end 72 of the second water pipe assembly moves towards the direction away from the end of the second water pipe assembly, so as to prevent the second water pipe assembly and the first water pipe assembly from being deformed and damaged, and the structure is shown in fig. 5 and 7.

In this embodiment, in order to improve the water outlet efficiency of the second water pipe assembly 7, the second water pipe assembly 7 includes a plurality of water outlet ends. A plurality of water outlet ends of the second water pipe assembly 7 are respectively arranged at two sides of the vehicle body chassis 1 of the water supply pump vehicle. The fire fighter connects the water intake device to the second water pipe assembly 7 so that the fire fighting equipment can be utilized to extinguish a fire in close proximity.

One end (e.g., a cylinder body) of the lift cylinder 41 is hinged to the base 12, the other end (e.g., a telescopic end) of the lift cylinder 41 is hinged to the second telescopic rail 24, and the other end (the telescopic end) of the lift cylinder 41 can reciprocate in the one end (the cylinder body) of the lift cylinder 41. The bracket 42 is disposed on the base 12, and the top of the bracket 42 is hinged to the second fixed rail 242 of the second telescopic rail 24. The telescopic end of the lifting cylinder 41 drives the telescopic water pipe assembly 2 on the second telescopic rail 24 to tilt upwards, because the top of the bracket 42 is hinged to the second sliding rail 241, the second telescopic rail 24 also rotates at the hinged position at the moment, so that the water pump 3 enters a water source, and the stability of the telescopic water pipe assembly 2 is ensured.

In some embodiments, the lifting mechanism includes a lifting motor, a drive pulley, and a driven pulley (not shown). The output shaft of the lifting motor is sleeved with the driving wheel, and the output shaft of the lifting motor is arranged on the chassis of the vehicle body through the motor support. And a driven wheel is arranged at the bottom of the second fixed rail of the second telescopic rail, and the driving wheel is meshed with the driven wheel. When the output shaft of the lifting motor rotates, power is transmitted to the driven wheel through the driving wheel to drive the second telescopic rail and the telescopic water pipe assembly to overturn.

Referring to fig. 12, 13, 14 and 15, the lifting mechanism of fig. 14 and 15 lifts the outlet end of the telescopic water tube assembly higher than that of fig. 12 and 13.

In this embodiment, the water supply system further comprises a swivel dial 9.

In this embodiment, the water inlet end of the retractable water pipe assembly is located at the tail of the vehicle body chassis and deviates from the head direction of the vehicle body chassis, and the water outlet end of the retractable water pipe assembly is located between the head of the vehicle body chassis and the water inlet end of the retractable water pipe assembly, and the structure is as shown in fig. 1 and fig. 2. Therefore, the telescopic water pipe assembly is convenient to rotate and lift. Because the middle part sets up parts such as fire hose winding mechanism before the automobile body chassis, if the end of intaking of flexible water pipe assembly passes through the gyration carousel and turns to car middle part, can bump with other parts.

In a preferred embodiment, the rotational range of the slew bearing is 0 ° to 180 °. The central axis of the telescopic water pipe assembly parallel to the width direction of the vehicle body chassis is taken as a reference, and the slewing bearing can drive the telescopic water pipe assembly to rotate for +90 degrees (the central axis in the width direction of the vehicle body chassis faces to the right side) or-90 degrees (the central axis in the width direction of the vehicle body chassis faces to the left side). Further avoiding the collision between the water inlet end of the telescopic water pipe assembly and the part on the chassis of the vehicle body.

The inner arc-shaped peripheral surface of the movable sleeve is movably sleeved on the outer arc-shaped peripheral surface of the body, and the multiple spherical joints are formed by communicating each spherical joint.

In this embodiment, the movable sleeve and the body may be sleeved by: the arc inner peripheral surface of the movable sleeve is movably hinged on the arc outer peripheral surface of the body, and the movable sleeve rotates by taking the hinged position as the center. Therefore, the movable sleeve can rotate on the body.

The arcuate outer peripheral surface of the body (which may be regarded as the first body 82) is formed into a hemispherical structure, and the arcuate inner peripheral surface of one end of the movable sleeve (which may be regarded as the first movable sleeve 81) is also formed into a hemispherical structure, and the hemispherical structures of the two are matched.

Specifically, the first water pipe assembly 6 and the fire hose 61 are connected by a section of movable portion as an example: the arc-shaped inner peripheral surface of one end of the movable sleeve (which can be regarded as a first movable sleeve 81) is hinged on the arc-shaped outer peripheral surface of the body (which can be regarded as a first body 82); meanwhile, an opening at one end of the movable sleeve (which can be regarded as a first movable sleeve 81) is communicated with an opening at one end of the body (which can be regarded as a first body 82); then the opening at the other end of the movable sleeve (which can be regarded as a first movable sleeve 81) is communicated with one end of the first water pipe assembly, and the opening at the other end of the body (which can be regarded as a first body 82) is communicated with the fire hose.

In the above, the first water pipe assembly 6 and the fire hose 61 are connected by one movable portion, and the first water pipe assembly 6 and the fire hose 61 are connected by a spherical joint of two movable portions: the first movable part comprises a first movable sleeve 81 and a first body 82, and the second movable part comprises a second movable sleeve 83 and a second body 84, which are structurally shown in fig. 7, 8, 9, 10 and 11; the inner cavity of the first movable sleeve 81 is communicated with the inner cavity of the first body 82, the inner cavity of the second movable sleeve 83 is communicated with the inner cavity of the second body 84, and the inner cavity of the second body 84 is communicated with the inner cavity of the second movable sleeve 83; specifically, an arc-shaped inner peripheral surface of one end of the first movable sleeve 81 is hinged to an arc-shaped outer peripheral surface of the first body 82, and the other end of the first movable sleeve 81 is connected to one end of the first water pipe assembly 6 (i.e., a water outlet end of the first water pipe assembly 6). The arc-shaped inner peripheral surface of the first movable sleeve 81 rotates around the hinge on the arc-shaped outer peripheral surface of the first body 82. The arc-shaped inner circumferential surface of one end of the second movable sleeve 83 is hinged to the arc-shaped outer circumferential surface of the second body 84. The other end of the second movable sleeve 83 is connected to one end (the end close to the first water pipe assembly 6) of the fire hose 61. The arc-shaped inner circumferential surface of the second movable sleeve 83 rotates around the hinge on the arc-shaped outer circumferential surface of the second body 84. The water flows from the water outlet end of the first water pipe assembly to the fire hose 61 through the inner cavity of the first movable sleeve 81, the inner cavity of the first body 82, the inner cavity of the second body 84 and the inner cavity of the second movable sleeve 83 in sequence.
