[0027] Embodiment 1

[0028] As Figure 1 shown, the utility model provides the pump truck of rescuing, include: water pump 5, first connecting pipe 1, second connecting pipe 2.As Figure 2 shown, water pump 5 has water inlet end and water outlet end, can carry out pumping, drainage, and the water inlet end of water pump 5 is horizontally connected with straight pipe 51 through flange, and straight pipe 51 is a section of small short pipe and is extended, and the water outlet end of water pump 5 is connected with elbow pipe 52, and the end of elbow pipe 52 away from water pump 5 is higher than the end of straight pipe 51 away from water pump 5, and the water inlet end of water pump 5 is located at one side of the pump truck when being on the pump truck, and the water outlet end is located at the other side of the pump truck, and the water outlet is higher than the water inlet, facilitating drainage;As Figure 3 shown, first connecting pipe 1 is obliquely arranged, and first connecting pipe 1 is made of hard material, and one end of first connecting pipe 1 is provided with first elbow 11, and the other end of first connecting pipe 1 is used to communicate with water inlet pipe 3, and the end of first elbow 11 away from first connecting pipe 1 is connected with straight pipe 51 through first connecting piece, that is to say, the first connecting piece connects the short pipe on the water inlet end of pump truck water pump 5 and first connecting pipe 1 together, and first elbow 11 is used to make first connecting pipe 1 be inclined when working;As Figure 4As shown, the second connecting pipe 2 is arranged obliquely, the second connecting pipe 2 is made of hard material, one end of the second connecting pipe 2 is used for communication with the water outlet pipe 4, the other end of the second connecting pipe 2 is connected with the elbow pipe 52 through the second connecting piece, that is, the second connecting piece connects the elbow pipe 52 on the water outlet end of the pump truck water pump 5 and the second connecting pipe 2 together, because the water outlet end of the water pump 5 is provided with the elbow pipe 52, so the second connecting pipe 2 is inclined during work. Among them, the first connecting pipe 1 is located on one side of the pump truck during use, the second connecting pipe 2 is located on the other side of the pump truck, and the first connecting pipe 1 and the second connecting pipe 2 are both inclined downward. The device is used to connect the first connecting pipe 1 made of hard material between the water inlet pipe 3 and the water inlet end of the pump truck water pump 5, and to connect the second connecting pipe 2 made of hard material between the water outlet pipe 4 and the water outlet end of the pump truck water pump 5. At present, the water inlet pipe and the water outlet pipe are connected with the water pump through aluminum alloy quick buckle, before the rescue, the heavy water inlet pipe and the water outlet pipe need to be lifted to align the connection, and the hinge angle requirement is very high, once the butt joint deviates, air leakage will occur, so a long time is needed to connect the water inlet pipe and the water outlet pipe, and the water inlet and outlet of the water pump are at a certain distance from the ground, which also increases the difficulty of aligning the water inlet pipe and the water outlet pipe. The first connecting pipe 1 and the second connecting pipe 2 can reduce the working surface of the water inlet pipe 3 and the water outlet pipe 4 during use, without lifting the heavy water inlet pipe 3 and the water outlet pipe 4 for connection, reducing the operation difficulty, and the first connecting pipe 1 and the second connecting pipe 2 are both in an inclined state during work, which can avoid the damage caused by the 90-degree dead angle of the water inlet pipe 3 and the water outlet pipe 4, and can also avoid the deformation of the water inlet pipe 3 and the water outlet pipe 4. The device is convenient to operate, saves human resources, improves the assembly speed of the machine pump, reduces the material loss of the water inlet and outlet pipes, reduces the working surface, is conducive to the adjustment of the machine position, improves the progress of emergency rescue work, and avoids the injury of rescue team members caused by the difficulty in controlling the original water inlet pipe 3 and the water outlet pipe 4. Among them, the water inlet pipe 3 and the water outlet pipe 4 in the device adopt nylon water hose, which can increase the friction of the pipe wall of the water inlet pipe 3 and the water outlet pipe 4, avoid the too smooth pipe wall to cause the injury of the rescue team members during rescue. In addition, the first elbow 11, that is, the elbow pipe and the following elbow, refer to the elbow pipe, which is a common structure in pipe materials, mainly plays the role of angle inclined connection, and the distance from the first connecting pipe 1 connected with the water inlet pipe 3 to the pump truck is equal to the distance from the second connecting pipe 2 connected with the water outlet pipe 4 to the pump truck, which is convenient for water pumping and drainage work.

[0029] The water inlet pipe and the water outlet pipe adopt rubber hose with steel wire,

[0030] The embodiment provides a specific mode of the first connecting piece and the second connecting piece. Further, the first connecting piece is a first flange plate 12, and the first flange plate 12 is used for connecting the first elbow 11 and the straight pipe 51, i.e. the water inlet end of the water pump 5 of the pump truck; the second connecting piece is a second flange plate 21, and the second flange plate 21 is used for connecting the second connecting pipe 2 and the elbow pipe 52, i.e. the water outlet end of the water pump 5 of the pump truck. In the embodiment, the first connecting piece and the second connecting piece are both flange connections. The first flange plate 12 and the second flange plate 21 can connect the water inlet end and the water outlet end of the pump truck with the first connecting pipe 1 and the second connecting pipe 2 together, and the flange connection belongs to detachable connection. After the rescue is completed, the first connecting pipe 1 and the second connecting pipe 2 and other structures can be conveniently detached and placed on the pump truck, so that the first connecting pipe 1 and the second connecting pipe 2 and other structures are convenient to detach and install.

[0031] Further, as shown in Figure 1 , the water pump 5 is installed on the pump truck body, the plane where the bottom surface of the water pump 5 is located is an installation working surface, the included angle between the first connecting pipe 1 and the installation working surface close to the side of the water pump 5 is 45°-55°, and the angle refers to the A angle in Figure 1 . The included angle between the second connecting pipe 2 and the installation working surface close to the side of the water pump 5 is 70°-75°, and the angle refers to the B angle in Figure 1 . The embodiment limits the working angles of the first connecting pipe 1 and the second connecting pipe 2, i.e. the working angle of the first connecting pipe 1 is 45°-55°, and the optimal angle is 45°. When the working angle of the first connecting pipe 1 is less than 45°, the first connecting pipe 1 is too close to the compartment of the pump truck, and the water pumping work is inconvenient. When the working angle of the first connecting pipe 1 is greater than 55°, the water inlet is inconvenient. The working angle of the second connecting pipe 2 is 70°-75°, and the optimal angle is 75°. When the working angle of the second connecting pipe 2 is less than 70°, the water outlet is inconvenient, and the original pump truck water pump needs to be greatly modified, and the cost is high. When the working angle of the second connecting pipe 2 is greater than 75°, the second connecting pipe 2 is too close to the compartment of the pump truck, and the water outlet work is inconvenient.
