[0003] When an existing emergency rescue vehicle is performing a fire extinguishing operation, the emergency rescue vehicle is generally driven to a designated location, and then a water pipe is connected to the water outlet pipe on the emergency rescue vehicle, so that the water in the emergency rescue vehicle is discharged through the water pipe by using the built-in water pump of the emergency rescue vehicle to perform the fire extinguishing operation. When the existing water pipe is connected to the water outlet pipe on the emergency rescue vehicle, it is generally connected by tightening, which makes the water pipe likely to be separated from the water outlet pipe when the water pipe is accidentally rotated during use. In addition, since this connection method is relatively simple, the connection between the water pipe and the water outlet pipe is not tight enough, which makes it easy for water to leak at the connection, thereby affecting the water pressure when the water pipe is discharged.

The two ends of the sealing tube 8 are respectively fixedly sleeved with a first plug ring 9 and a second plug ring 10, and the first plug ring 9 is closer to the water receiving pipe 5 than the second plug ring 10. The free ends of the first plug ring 9 and the second plug ring 10 are both facing the water receiving pipe 5, and the outer diameters of the first plug ring 9 and the second plug ring 10 are the same as the inner diameters of the water receiving pipe 5 and the water outlet pipe 3. A pushing component 11 is arranged on the end of the sealing tube 8 close to the second plug ring 10, and the first sealing ring 12 and the second sealing ring 13 are respectively fixedly connected in the water receiving pipe 5 and the water outlet pipe 3, and the second sealing ring 13 is located between the first plug ring 9 and the second plug ring 10, and the first sealing ring 12 and the second sealing ring 13 are both provided with an annular sealing groove on the side close to the second plug ring 10, and the sealing groove on the first sealing ring 12 and the sealing groove on the second sealing ring 13 are matched with the first plug ring 9 and the second plug ring 10 respectively.

[0034] The pushing assembly 11 includes a push rod 111 coaxial with the water outlet pipe 3, and one end of the push rod 111 close to the water receiving pipe 5 is rotatably sleeved with a fixing ring 112, and a plurality of fixing rods 113 are fixedly connected between the fixing ring 112 and the inner wall of the sealing tube 8, and the part of the push rod 111 located in the sealing tube 8 is fixedly sleeved with an impeller 114, and the diameter of the impeller 114 matches the inner diameter of the sealing ring, and the part of the push rod 111 located outside the sealing tube 8 is movably sleeved with a fixing plate 115, and both ends of the fixing plate 115 are fixedly connected to the inner wall of the water outlet pipe 3, and one end of the push rod 111 away from the fixing ring 112 is rotatably connected with a pressing block 116, and a return spring 117 is fixedly connected between the pressing block 116 and the fixing plate 115, and the return spring 117 is sleeved on the push rod 111;

[0035] Before performing some fire fighting and rescue or remote water supply operations, the water receiving pipe 5 can be connected to the water pipe for water supply, and the water receiving pipe 5 can be stored in the groove on the side of the vehicle body 1 as a part of the water pipe. When fire fighting and rescue or remote water supply is needed, the protective cover 2 is opened, the water pipe with the water receiving pipe 5 is taken out from the groove, and then the water receiving pipe 5 is connected to the water outlet. The specific connection operation is as follows: first, the port of the water receiving pipe 5 is kept parallel to the port of the water outlet pipe 3, and then the two limit blocks 6 on the water receiving pipe 5 are distributed up and down and are located on one side of the water outlet pipe 3, and then the water receiving pipe 5 is close to the port of the water outlet pipe 3 to drive the limit block 6 to the card block 4, and with the movement of the water receiving pipe 5, the top and bottom edges of the water receiving pipe 5 can be respectively inserted between the two clamping blocks 4, and when the limit block 6 contacts the clamping block 4, the connection between the water receiving pipe 5 and the water outlet pipe 3 is completed, at which time the port of the water receiving pipe 5 and the port of the water outlet pipe 3 remain aligned, and then the two hanging rods 72 are pushed downward by the U-shaped rod 73, so that the two hanging rods 72 can gradually approach the two locking rods 71, and when the hanging rod 72 is deflected to a horizontal state, the two hanging rods 72 can just cooperate with the two locking rods 71 ​​to lock the water receiving pipe 5 and the water outlet pipe 3, thereby preventing the water receiving pipe 5 and the water outlet pipe 3 from being separated due to accidental twisting or shaking;

[0036] When the water pump in the water tank of the vehicle body 1 is turned on, as the water flows from the water outlet pipe 3 to the water receiving pipe 5, when the water flows hit the impeller 114 on the push rod 111, the impeller 114 can not only start to drive the push rod 111 to rotate under the action of the water flow, but also can drive the push rod 111 to move towards the direction close to the water receiving pipe 5 under the push of the water flow. As the push rod 111 moves, the first plug ring 9 and the second plug ring 10 on the sealing tube 8 can approach the first sealing ring 12 and the second sealing ring 13 respectively, and the pressing block 116 can gradually compress the return spring 117 under the drive of the push rod 111. When the first plug ring 9 and the second plug ring 10 are respectively inserted into the sealing grooves on the first sealing ring 12 and the second sealing ring 13, the sealing tube 8 can further seal the connection between the water receiving pipe 5 and the water outlet pipe 3, thereby improving the sealing performance of the connection between the water receiving pipe 5 and the water outlet pipe 3, avoiding water overflow, and then ensuring the water pressure of the water outlet pipe 3.

[0037] When the fire is extinguished and rescue is completed, as the water pump is turned off, the return spring 117 can drive the push rod 111 and the sealing tube 8 to move out of the water receiving pipe 5 by pushing the pressure block 116. Then, when the locking assembly 7 is opened, the water receiving pipe 5 can be pushed horizontally so that the water receiving pipe 5 and the water outlet pipe 3 are quickly separated.

[0038] like Figure 1 and Figure 2 As shown, a retractable ladder 14 is installed on the top of the vehicle body 1, a lighting lamp 15 is installed on the ladder 14, and an escalator 16 is hung on the side of the vehicle body 1 away from the groove;

[0039] By providing a retractable ladder 14, high-altitude rescue can be carried out on the rescue site, and the lighting lamp 15 on the ladder 14 can perform high-altitude lighting operations to improve the convenience of rescue, while the escalator 16 can be used for rescue operations in some shorter areas.

[0040] like Figure 2 As shown, a towing hook 17 is connected to the rear side of the vehicle body 1, and the towing hook 17 can be used to tow a mobile drainage pump;

[0041] By providing the towing hook 17 , when drainage rescue is required, a mobile drainage pump (not shown in the figure) can be connected to the towing hook 17 , so that the mobile drainage pump can be pulled to the rescue site for drainage operation.

[0042] like Figure 4 and Figure 5 As shown, the sealing tube 8 is fixedly connected to a magnetic ring 18 on one side facing the first sealing ring 12, the magnetic poles of the two magnetic rings 18 facing each other are opposite, and the suction force between the two magnetic rings 18 is smaller than the maximum elastic force of the reset spring 117;

[0043] By providing the magnetic ring 18, when the first plug-in ring 9 and the second plug-in ring 10 are respectively plugged together with the first sealing ring 12 and the second sealing ring 13, the two magnetic rings 18 on the sealing tube 8 and the first sealing ring 12 can be adsorbed together, thereby cooperating with the thrust of the water flow on the impeller 114 so that the sealing tube 8 can be more stably connected to the connection between the water outlet pipe 3 and the water receiving pipe 5, thereby improving the sealing between the water outlet pipe 3 and the water receiving pipe 5.

[0044] like Figure 4 As shown, the thickness of the first insert ring 9 and the second insert ring 10 gradually becomes thinner towards the water receiving pipe 5, and the inner sides of the first insert ring 9 and the second insert ring 10 are both conical surfaces, and the inner sides of the first insert ring 9 and the second insert ring 10 are fixedly connected with a rubber pad 19;

[0045] By designing the outer sides of the first plug-in ring 9 and the second plug-in ring 10 as conical surfaces, when the first plug-in ring 9 and the second plug-in ring 10 are respectively inserted into the corresponding sealing grooves, the conical surfaces can increase the contact areas between the first plug-in ring 9 and the second plug-in ring 10 and the corresponding sealing grooves, and cooperate with the rubber pad 19 to increase the sealing between the first plug-in ring 9 and the first sealing ring 12 and the second plug-in ring 10 and the second sealing ring 13, thereby improving the sealing effect of the sealing tube 8 at the connection between the docking water pipe 5 and the water outlet pipe 3.

[0046] like Figure 4 and Figure 5 As shown, a ring groove is formed on one side of the second sealing ring 13 close to the second plug ring 10, a sealing ring 20 is slidably inserted in the ring groove, and a compression spring 21 is fixedly connected between the sealing ring 20 and the ring groove;

[0047] By providing the sealing ring 20, when the sealing tube 8 drives the second plug-in ring 10 and the second sealing ring 13 to be plugged together under the push of the impeller 114, as the sealing ring 20 and the second plug-in ring 10 are pressed together, the compression spring 21 can be gradually compressed, and the reaction force of the compression spring 21 on the sealing ring 20 can make the sealing ring 20 and the second plug-in ring 10 fit tightly together, thereby increasing the sealing between the second plug-in ring 10 and the second sealing ring 13.

[0048] like Figure 6 As shown, the end of the water receiving pipe 5 close to the water outlet pipe 3 is fixedly connected with an annular sealing gasket 22, and the sealing gasket 22 is made of wear-resistant rubber material;

[0049] By providing the sealing gasket 22 , when the water outlet pipe 3 and the water receiving pipe 5 are connected together through the locking rod 71 and the hanging rod 72 , the sealing gasket 22 can fit tightly with the water outlet pipe 3 , thereby further improving the sealing between the water outlet pipe 3 and the water receiving pipe 5 .

[0050] The present invention also provides a rescue method for a multifunctional emergency rescue drainage vehicle and a remote water supply vehicle, the method comprising the following steps:

[0051] Step 1: When performing remote water supply or fire fighting rescue, first fill the water tank in the vehicle body with water, and then drive the vehicle to the destination;

[0052] Step 2: Open the protective cover 2, connect the water inlet pipe 5 to the water pipe that needs to supply water, then connect the water inlet pipe 5 to the water outlet pipe 3 by horizontal plugging, and then lock the water inlet pipe 5 and the water outlet pipe 3 by the locking assembly 7;

[0053] Step 3: Turn on the water pump to supply water or perform firefighting and rescue operations to the target through the connected water pipe;

[0054] Step 4: After the water supply is completed, turn off the water pump and remove the water connecting pipe 5.
