[0083] Please refer to Figures 1 to 15 , this embodiment provides a mother - child type emergency rescue drainage vehicle, including:

[0084] A first chassis 1 that can move;

[0085] A mobile pumping station 2, the mobile pumping station includes a second chassis 22 that can move and a drainage pump 21 arranged on the second chassis 22. The second chassis 22 that can move is used to drive the drainage pump 21 to approach the operation point to perform drainage operations;

[0086] A remote water supply device 3, the remote water supply device 3 includes a fire pump 31, a bracket 32 and a shock absorber 33. The fire pump 31 is a liquid - above pump. The fire pump 31 is arranged on the first chassis 1 through the bracket 32 and the shock absorber 33 for performing remote water supply operations.

[0087] It should be noted that the pumping station is an important infrastructure in irrigation and drainage of water conservancy projects and urban flood control and drainage, responsible for agricultural and urban irrigation and drainage, flood control and waterlogging drainage, as well as water supply for industrial and agricultural production and urban and rural residents' lives. If a temporary pumping station is built, time does not permit, and it is also uneconomical. Therefore, the mobile pumping station 2 came into being. The mobile pumping station 2 has a drainage pump 21 and a second chassis 22 that can move, can be self-sufficient, quickly arrive at the site where pumping and emergency rescue are needed, quickly put into drainage operations, and is less affected by terrain and ground conditions, and can adapt to low, short, narrow operating environments and complex road conditions. The volume of the first chassis 1 is larger than that of the second chassis 22, which plays the role of transporting and storing the mobile pumping station 2. When performing drainage operations, the mobile pumping station 2 can be controlled to drive away from the first chassis 1 to the drainage operation point. After the drainage operation is completed, the mobile pumping station 2 can be controlled to drive onto the first chassis 1.

[0088] Different from the prior art, the above technical solution has the following beneficial effects:

[0089] By equipping two types of pump bodies, the mother-child type emergency drainage vehicle can cope with different drainage needs, improving the flexibility and efficiency of the equipment. The mobile pumping station is small in volume and can be moved to positions where the first chassis is not easy to walk. The drainage pump 21 is responsible for pumping water. The first chassis is large in volume, and the fire pump 31 can provide a greater lift and can pressurize and transport water to farther and higher places. The remote water supply capacity avoids the need to deploy additional pressurization devices in complex environments.

[0090] The function of the bracket 32 is to provide a solid and reliable platform for supporting the fire pump 31 and ensuring its safety and stability under various operating conditions. The shock absorber 33 can reduce the vibration during the operation of the fire pump 31 and the impact on the fire pump 31 caused by the bumps during the driving of the drainage vehicle, helping to maintain the smoothness of the fire pump 31.

[0091] Please refer to Figure 3 , in this embodiment, the rated outlet pressure of the drainage pump 21 of the mobile pumping station 2 is less than the rated outlet pressure of the water supply pump of the remote water supply device 3, the lift of the drainage pump 21 of the mobile pumping station 2 is less than the lift of the fire pump 31 of the remote water supply device 3. The lift of the drainage pump 21 of the mobile pumping station 2 is relatively small, and the lift of the fire pump 31 of the remote water supply device 3 is relatively large. Compared with the drainage pump 21, the height that the fire pump 31 can lift water is greater than the height that the drainage pump 21 can lift water.

[0092] In this embodiment, the working part of the above-ground pump is separated from the liquid and is located above the liquid surface. The above-ground pump is a kind of pump that inputs the liquid into the pump body through a pipeline and then conducts operations.

[0093] In this embodiment, the shock absorber 33 can be a spring shock absorber, a hydraulic shock absorber, a rubber shock absorber, etc. The shock absorber 33 can be provided between the fire pump 31 and the bracket 32, and can directly absorb the vibration generated by the operation of the fire pump 31, preventing these vibrations from being transmitted to the bracket 32 and the entire vehicle structure, thereby reducing the overall vibration amplitude. Alternatively, the shock absorber 33 can be provided between the fire pump 31 and the first chassis 1, which will not only absorb the vibration of the fire pump 31, but also, to a certain extent, isolate the impact of the ground bumps during vehicle driving on the fire pump 31.

[0094] Please refer to Figures 1 to 4 , in this embodiment, the fire pump 31 is a high and low pressure fire pump 31, and its rated outlet pressure is above 0.8 Mpa (megapascal, a pressure unit). The outlet pressure can be detected by a pressure sensor. The rated outlet pressure can be detected by a pressure sensor. When the fire pump 31 is in the rated power state and the outlet pressure is greater than or equal to 0.8 MPa, it can ensure that the fire pump 31 has a large lift and can perform remote water supply operations. When the fire pump 31 is in the rated state, its rated outlet pressure can be 0.8 MPa, 1.0 MPa, 1.5 MPa, 3.0 MPa, 3.5 MPa, 4.0 MPa, etc., depending on the actual needs. Taking the rated outlet pressure of the fire pump 31 being 0.8 MPa as an example, in the case of changing the speed or pressure of the fire pump 31 to make the fire pump 31 in a light load state with its water outlet pressure less than 0.8 MPa, such a technical solution also belongs to the protection scope of this application.

[0095] In this embodiment, the rated outlet pressure of the fire pump is 1 MPa and its lift is 100 meters. When the fire pump and the drainage pump are connected to the same water delivery pipe (DN200, with a diameter of 200 millimeters), the distance that the fire pump can deliver water is about 1600 meters, and the distance that the drainage pump can deliver water is about 200 meters.

[0096] In this embodiment, the fire pump 31 is provided with a water outlet channel 3112, and the water outlet channel 3112 is detachably connected to the plate member 35, and the plate member 4 is connected to the first chassis 1 or the bracket 32. The plate member 35 can be connected to the first chassis 1 (such as the beam 11 and the subframe 12) or the bracket 32 through detachable structures such as bolts and buckles, where Figure 9 it is shown that the upper and lower ends of the L-shaped plate member 4 are respectively fastened to the beam 11 and the water outlet channel 3112 by bolts, ensuring the stability and safety of the water outlet channel 3112 during normal use.

[0097] The following shows several different embodiments in which the fire pump 31 is provided on the first chassis 1 through the bracket 32 and the shock absorber 33, which will be introduced separately.

[0098] First Embodiment

[0099] The core of this embodiment lies in that the fire pump 31 is installed on the subframe 12 of the first chassis 1.

[0100] Please refer to Figures 1 to 4 , in this embodiment, the first chassis 1 has a girder 11 and a subframe 12 located above the girder 11. The fire pump 31 is provided on the upper surface of the subframe 12 through a bracket 32 and a shock absorber 33. There are two girders 11, and the two girders 11 extend along the length direction (longitudinal direction) of the first chassis 1. They are reinforced by several cross beams between them to form a solid first chassis 1. The overall structure of the subframe 12 is generally plate-shaped, supported on the two girders 11, and the subframe 12 and the girder 11 are usually bolted together. The subframe 12 can provide a support platform for the carriage, the fire pump 31, and the mobile pumping station 2.

[0101] Please refer to Figure 1 and Figure 4 , in this embodiment, the fire pump 31 is provided with a water inlet channel 3111 and a water outlet channel 3112. The subframe 12 is provided with slots for the water inlet channel 3111 and the water outlet channel 3112 to penetrate through. The water inlet of the water inlet channel 3111 and the water outlet of the water outlet channel 3112 are located below the subframe 12. The overall part of the fire pump 31 is above the subframe 12, while the water inlet channel 3111 and the water outlet channel 3112 extend from top to bottom and extend through the slots to the lower part of the subframe 12, which is convenient for connecting drainage pipes and ground water sources and is easy to use. Among them, one end (water inlet) of the water inlet channel 3111 and one end (water outlet) of the water outlet channel 3112 are both designed in a form that can be connected to external drainage pipes, such as quick-release joints and fire hydrant connections, so as to facilitate quick access and separation.

[0102] Please refer to Figure 4 and Figure 5 , in this embodiment, the fire pump 31 includes a pump casing 311 and a gearbox 312. The impeller shaft in the pump casing 311 is connected to the output end of the gearbox 312. The bracket 32 includes a first transverse frame 321. The pump casing 311 and the gearbox 312 are both provided on the first transverse frame 321, and the first transverse frame 321 is provided on the upper surface of the subframe 12. The pump casing 311 and the gearbox 312 are arranged at intervals on the first transverse frame 321. The pump casing 311 has a water inlet channel 3111 and a water outlet channel 3112. The pump casing 311 is the main component of the fire pump 31, and its interior houses the impeller shaft and the impeller, which generates power by rotation to suck water from the water inlet and discharge it from the water outlet. The impeller shaft of the fire pump 31 is driven by the output end of the gearbox 312. The gearbox 312 can adjust the rotational speed of the impeller shaft according to actual needs to adapt to different water supply or drainage requirements, especially increasing the rotational speed of the impeller shaft to make it better pressurize. The first transverse frame 321 is overall horizontal and extends horizontally, Figure 5It is shown that it is specifically in the shape of a straight plate frame and is made of high-strength materials. The use of the first horizontal frame 321 ensures the stability of the fire pump 31 during vehicle driving or operation, reduces vibration and displacement, and protects the normal operation of the fire pump 31.

[0103] Please refer to Figure 2 and Figure 6 , in this embodiment, the shock absorber 33 includes a first shock absorber 331. At least one first shock absorber 331 is provided between the pump housing 311 and the first horizontal frame 321, which can directly absorb the vibration of the pump housing 311 in the working state, reduce the stress at the connection between the pump housing 311 and the first horizontal frame 321, and protect the sealing performance and structural integrity of the pump housing 311. The number of the first shock absorbers 331 can be 1, or 2, 3, 4, etc., depending on the actual needs. The same applies to the first shock absorber 331 and the second shock absorber 332 below. Among them, an even number of first shock absorbers 331 is preferred, and these even-numbered first shock absorbers 331 are symmetrically arranged.

[0104] Specifically, the first shock absorber 331 includes a first shock pad 3311 and a first protective plate 3312. The pump housing 311 fixes the first shock pad 3311, the first protective plate 3312 and the first horizontal frame 321 through bolts. The first shock pad 3311 is made of materials with high elasticity and good durability, such as rubber or polyurethane, and is used to absorb and reduce vibration energy. The first protective plate 3312 is made of metal or composite materials and has a certain rigidity, which is used to protect the first shock pad 3311, avoid damage caused by direct contact with the external environment, and also provides fixed points.

[0105] Bolt connection is a commonly used mechanical fastening method for fixing two or more parts together. It ensures the reliability and stability of the connection through the self-locking characteristic of the thread and the action of the pre-tightening force. Moreover, the bolt connection method is convenient for the installation and disassembly of the fire pump 31. Bolt connection can be divided into two basic types: the connection of bolts and screw holes, and the connection of bolts and nuts. For example, in the way of using bolts and nuts, that is, through holes are provided on the first shock pad 3311, the first protective plate 3312 and the first horizontal frame 321 that penetrate up and down. The first through hole 3211 on the first horizontal frame 321 is as Figure 5 shown. When the bolt passes through the pump housing 311, the first shock pad 3311, the first protective plate 3312 and the first horizontal frame 321, the nut is screwed tightly on the bolt, and the pump housing 311, the first shock pad 3311, the first protective plate 3312 and the first horizontal frame 321 are fastened together through the friction force and pre-tightening force between the threads.

[0106] Please refer to Figure 4 , Figure 7 and Figure 8, in this embodiment, at least one first shock absorber 331 is provided between the transmission 312 and the first transverse frame 321, which can effectively isolate the vibration generated by the transmission 312 during the speed change process, prevent the vibration from being transmitted to the entire vehicle structure, and protect the internal gears and bearings of the transmission 312 from additional wear.

[0107] Specifically, the first shock absorber 331 includes a first shock pad 3311 and a first protective plate 3312. The transmission 312 fixes the first shock pad 3311, the first protective plate 3312 and the first transverse frame 321 by bolts.
