[0080] See also Figures 1 to 15 This embodiment provides an emergency drainage vehicle, comprising:

[0081] Chassis 1;

[0082] The drainage device 2 includes a drainage pump 21 and an adjustment mechanism 22. The drainage pump 21 is arranged on the chassis 1 through the adjustment mechanism 22. The adjustment mechanism 22 is used to adjust the position of the drainage pump 21 so that it is close to or away from the working point to perform the drainage operation; and

[0083] 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 pump. The fire pump 31 is arranged on the chassis 1 through the bracket 32 and the shock absorber 33 for performing remote water supply operations.

[0084] Different from the existing technology, the above technical solution has the following beneficial effects:

[0085] Equipped with two pumps, this emergency drainage vehicle can respond to diverse drainage needs, enhancing its flexibility and efficiency. Drainage pump 21 directly extracts water from low-lying areas, while adjustment mechanism 22 allows for vertical and horizontal movement within a certain range, enabling more precise targeting of the required drainage location. Fire pump 31 provides a greater head, enabling pressurized water to be delivered to greater distances and heights. This remote water supply capability eliminates the need for additional pressurization equipment in complex environments.

[0086] The bracket 32 provides a sturdy and reliable platform for supporting the fire pump 31 and ensuring its safety and stability under various operating conditions. The shock absorber 33 reduces vibration during operation of the fire pump 31 and the impact of bumps caused by the drainage truck during driving, helping to maintain the stability of the fire pump 31.

[0087] See also Figure 3In this embodiment, the rated outlet pressure of the drainage pump 21 of the drainage device 2 is less than the rated outlet pressure of the water supply pump of the remote water supply device 3, and the lift of the drainage pump 21 of the drainage device 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 drainage device 2 is smaller, and the lift of the fire pump 31 of the remote water supply device 3 is larger. Compared with the drainage pump 21, the height to which the fire pump 31 can lift water is greater than that to which the drainage pump 21 can lift water.

[0088] In this embodiment, the operating part of the liquid-surface pump is separated from the liquid and is located above the liquid surface. The liquid-surface pump is a pump that inputs liquid into the pump body through a pipeline to perform operations.

[0089] In this embodiment, the shock absorber 33 can be a spring shock absorber, a hydraulic shock absorber, a rubber shock absorber, or the like. The shock absorber 33 can be positioned between the fire pump 31 and the bracket 32 to directly absorb vibrations 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 positioned between the fire pump 31 and the chassis 1, not only absorbing vibrations from the fire pump 31 but also, to a certain extent, isolating the fire pump 31 from the effects of ground bumps during vehicle operation.

[0090] See also 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 (megapascals, a unit of pressure). 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, the outlet pressure is greater than or equal to 0.8 MPa, which can ensure that the fire pump 31 has a large head 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 actual needs. Taking the rated outlet pressure of 0.8 MPa of the fire pump 31 as an example, when the speed or pressure of the fire pump 31 is changed, the fire pump 31 is in a light-load state, and its water outlet pressure is less than 0.8 MPa. Such a technical solution also falls within the scope of protection of this application.

[0091] In this embodiment, the rated outlet pressure of the fire pump is 1 MPa, and the head thereof is 100 meters. When the fire pump is connected to a DN200 water pipe, the distance that the fire pump can deliver water is about 1600 meters.

[0092] See also Figure 3In this embodiment, the drainage device 2 is an existing technology, and the drainage operation can be achieved through its drainage pump 21, and the drainage pump 21 can be driven close to or away from the operation point through the adjustment mechanism 22 with lifting and rotating functions to perform the drainage operation. The structure of the drainage device 2 can refer to patents No. 202223604784.8, 201810689368.1, 201020166069.9 and other patents.

[0093] In this embodiment, the fire pump 31 is provided with a water outlet channel 3112, which is detachably connected to the plate 35, and the plate 4 is connected to the chassis 1 or the bracket 32. The plate 35 can be connected to the chassis 1 (such as the beam 11, the subframe 12) or the bracket 32 by a detachable structure such as bolts or buckles, wherein Figure 9 The upper and lower ends of the L-shaped plate 4 are fastened to the beam 11 and the water outlet channel 3112 by bolts, respectively, ensuring the stability and safety of the water outlet channel 3112 during normal use.

[0094] The following illustrates several different embodiments in which the fire pump 31 is mounted on the chassis 1 via the bracket 32 and the shock absorber 33 , which will be introduced separately.

[0095] First embodiment

[0096] The core of this embodiment is that the fire pump 31 is installed on the subframe 12 of the chassis 1 .

[0097] See also Figures 1 to 4 In this embodiment, the chassis 1 includes a main beam 11 and a subframe 12 positioned above the main beam 11. The fire pump 31 is mounted on the upper surface of the subframe 12 via a bracket 32 and a shock absorber 33. There are two main beams 11, extending along the length (longitudinal direction) of the chassis 1. A plurality of crossbeams reinforce the two main beams, forming a sturdy chassis 1. The subframe 12 has a generally plate-like structure and is supported by the two main beams 11. The subframe 12 and the main beams 11 are typically connected by bolts. The subframe 12 provides a support platform for the vehicle compartment, the fire pump 31, or other emergency equipment.

[0098] See also Figure 1 and Figure 4In this embodiment, the fire pump 31 is provided with a water inlet channel 3111 and a water outlet channel 3112, and the sub-frame 12 is provided with a slot through which the water inlet channel 3111 and the water outlet channel 3112 pass. The water inlet of the water inlet channel 3111 and the water outlet of the water outlet channel 3112 are located below the sub-frame 12. The entire fire pump 31 is above the sub-frame 12, while the water inlet channel 3111 and the water outlet channel 3112 extend from top to bottom and extend to the bottom of the sub-frame 12 through the slot, making it easy to connect to a drainage pipe or ground water source, and convenient to use. Among them, one end of the water inlet channel 3111 (water inlet) and one end of the water outlet channel 3112 (water outlet) are designed to be connected to an external drainage pipe, such as a quick-release head or fire connector, to facilitate quick connection and separation.

[0099] See also 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 arranged on the first transverse frame 321. The first transverse frame 321 is arranged on the upper surface of the sub-frame 12. The pump casing 311 and the gearbox 312 are spaced apart 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. It houses the impeller shaft and impeller. It generates power by rotating 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 speed of the impeller shaft according to actual needs to adapt to different water supply or drainage requirements, especially to increase the speed of the impeller shaft to better pressurize it. The first transverse frame 321 is horizontal as a whole and extends laterally. Figure 5 The first transverse frame 321 is shown to be in a straight frame shape and made of high-strength material. The use of the first transverse 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.

[0100] See also Figure 2 and Figure 6In this embodiment, the shock absorber 33 includes a first shock absorber 331. At least one first shock absorber 331 is disposed between the pump housing 311 and the first transverse frame 321. This first shock absorber 331 can directly absorb vibrations of the pump housing 311 during operation, reducing stress on the connection between the pump housing 311 and the first transverse frame 321, thereby protecting the sealing and structural integrity of the pump housing 311. The number of first shock absorbers 331 can be one, two, three, or four, depending on actual needs. This also applies to the first shock absorbers 331 and second shock absorbers 332 described below. An even number of first shock absorbers 331 is preferred, and these even numbered first shock absorbers 331 are symmetrically arranged.

[0101] Specifically, the first shock absorber 331 includes a first shock-absorbing pad 3311 and a first protective plate 3312. The pump housing 311 is secured to the first shock-absorbing pad 3311, the first protective plate 3312, and the first transverse frame 321 via bolts. The first shock-absorbing pad 3311 is made of a highly elastic and durable material, such as rubber or polyurethane, and is used to absorb and dissipate vibration energy. The first protective plate 3312 is made of a metal or composite material and has a certain degree of rigidity. It protects the first shock-absorbing pad 3311 from direct contact with the external environment and also provides a fixing point.

[0102] 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 characteristics of the thread and the effect of the preload. Moreover, the bolt connection method facilitates the installation and disassembly of the fire pump 31. Bolt connections can be divided into two basic types: connections in which bolts match screw holes, and connections in which bolts match nuts. For example, in the manner of bolts and nuts, a first through hole that runs through the first shock-absorbing pad 3311, the first protective plate 3312 and the first transverse frame 321 is provided with, as shown in FIG. Figure 5 As shown, after the bolt passes through the pump casing 311, the first shock-absorbing pad 3311, the first protective plate 3312 and the first transverse frame 321, the nut is tightened on the bolt, and the pump casing 311, the first shock-absorbing pad 3311, the first protective plate 3312 and the first transverse frame 321 are fastened together by the friction force and pre-tightening force between the threads.

[0103] See also Figure 4 、 Figure 7 and Figure 8 In this embodiment, at least one first shock absorber 331 is provided between the gearbox 312 and the first transverse frame 321, which can effectively isolate the vibration generated by the gearbox 312 during the speed shifting process, prevent the vibration from being transmitted to the entire vehicle structure, and protect the internal gears and bearings of the gearbox 312 from additional wear.

[0104] Specifically, the first shock absorber 331 includes a first shock absorbing pad 3311 and a first protective plate 3312. The gearbox 312 is fixed to the first shock absorbing pad 3311, the first protective plate 3312 and the first transverse frame 321 by bolts. For example, a bolt and nut are used to match, that is, the first shock absorbing pad 3311, the first protective plate 3312 and the first transverse frame 321 are all provided with a second through hole that passes through from top to bottom. The second through hole 3212 on the first transverse frame 321 is as shown in FIG. Figure 5 As shown, after the bolt 3313 passes through the gearbox 312, the first shock-absorbing pad 3311, the first protective plate 3312 and the first transverse frame 321, the structure is as shown in FIG. Figure 7 As shown, the nut is screwed onto the bolt, and the housing of the gearbox 312, the first shock-absorbing pad 3311, the first protective plate 3312 and the first transverse frame 321 are fastened together through the friction force between the threads and the pre-tightening force.

[0105] In this embodiment, the first protective plate 3312 can be connected to the first transverse frame 321 by bolts 3314, for example Figure 7 、 Figure 8 The first protective plate 3312 below the gearbox 312 is fastened to the first transverse frame 321 by four bolts. Figure 7 Three of the bolts can be seen above, and the other bolt is obscured. Figure 8 Two of the bolts are visible, while the other two are obscured.

[0106] In certain embodiments, at least one first shock absorber 331 is disposed between the first transverse frame 321 and the subframe 12 to absorb vibrations caused by vehicle travel and ensure stable operation of the fire pump 31. The first shock absorber 331 includes a first shock-absorbing pad 3311 and a first protective plate 3312. The first transverse frame 321 is secured to the subframe 12 via bolts. For example, a bolt and nut arrangement is employed, whereby the first shock-absorbing pad 3311, the first protective plate 3312, and the first transverse frame 321 are each provided with a third through-hole extending vertically therethrough. After the bolt passes through the first transverse frame 321, the first shock-absorbing pad 3311, the first protective plate 3312, and the subframe 12, the nut is tightened onto the bolt. Friction between the threads and a preload force secure the first transverse frame, the first shock-absorbing pad 3311, the first protective plate 3312, and the subframe 12 together.

[0107] In a preferred embodiment, two first shock absorbers 331 are provided between the pump housing 311 and the first transverse frame 321, and four first shock absorbers 331 are provided between the gearbox 312 and the first transverse frame 321 to evenly distribute and absorb the vibration generated by the operation of the fire pump 31. The first transverse frame 321 is welded to the upper surface of the subframe 12 to ensure the stability of the installation of the fire pump 31 and the rigidity of the overall structure.

[0108] See also Figure 4 In this embodiment, the remote water supply device 3 also includes a motor 34, the bracket 32 includes a first transverse frame 321 and a first fixing frame 322, the fire pump 31 is mounted on the first transverse frame 321 by bolts, the first transverse frame 321 is welded to the upper surface of the sub-frame 12, the first fixing frame 322 is spaced apart from the first transverse frame 321, the lower part of the first fixing frame 322 is arranged on the upper surface of the sub-frame 12, the upper part of the first fixing frame 322 has a vertically extending first mounting plate 3221, the first mounting plate 3221 is mounted on the motor 34 by bolts, the first mounting plate 3221 has a circular hole for the motor 34 to pass through, and the output shaft of the motor 34 is connected to the fire pump 31.

[0109] The first fixing bracket 322 is spaced apart from the first transverse frame 321. Its lower portion is also mounted on the upper surface of the subframe 12, while its upper portion includes a vertically extending first mounting plate 3221. This mounting plate is bolted to the motor 34, forming a mounting base for the motor 34. Preferably, the first mounting plate 3221 has a plurality of positioning holes arranged in a circular pattern around its circular hole, through which the motor 34 passes. A corresponding number of bolts are inserted through these positioning holes, and nuts are used to secure the motor 34.

[0110] Generally speaking, the fire pump 31 comprises a pump housing 311 with an internal impeller and a gearbox 312. The output shaft of the motor 34 is connected to the input of the gearbox 312. When the motor 34 is started, it transmits power through the gearbox 312 to the impeller within the pump housing 311, driving the impeller to rotate and initiate pressurization and drainage. In certain embodiments, if the motor 34 also functions as the gearbox 312, the fire pump 31 may consist solely of the pump housing 311 with the internal impeller. This is also possible, as the motor 34's increased speed increases the impeller's speed, generating pressure to increase pressure.

[0111] In this embodiment, the fire pump 31 is located at the front end of the sub-frame 12 , which can free up space in the middle and rear ends of the sub-frame 12 for other emergency devices, such as the drainage device 2 .

[0112] Second embodiment

[0113] The core of this embodiment lies in that the fire pump 31 is installed on the girder 11 of the chassis 1. In addition, the fire pump 31 can be ingeniously installed under the subframe 12. The same as the first embodiment is that the structure of the chassis 1 is the same, and the functions that the fire pump 31 can achieve are the same. The general difference lies in that the installation position of the fire pump 31 is different, the structure of the bracket 32 is different, and the structure of the shock absorber 33 is different.

[0114] Please refer to Figure 9 , in this embodiment, the chassis 1 has two girders 11 arranged side by side left and right. The two girders 11 extend along the length direction of the chassis 1. The fire pump 31 and the shock absorber 33 are arranged on the side of the girder 11 through the bracket 32, and the fire pump 31 is located between the two girders 11. Generally speaking, the fire pump 31 includes a pump housing 311 with an impeller built therein and a gearbox 312. At this time, preferably both the pump housing 311 and the gearbox 312 are between the two girders 11, which helps to optimize the utilization of the vehicle interior space and is also beneficial to controlling the vehicle's center of gravity.

[0115] Please refer to Figure 9 and Figure 10 , in this embodiment, the bracket 32 includes a second transverse frame 323 and a longitudinal frame 325. The second transverse frame 323 is installed on the fire pump 31 through bolts. Longitudinal frames 325 are respectively arranged on both sides of the second transverse frame 323. The two longitudinal frames 325 are located on both sides of the fire pump 31, and the longitudinal frames 325 are installed on the side of the girder 11 through bolts. One longitudinal frame 325 corresponds to one girder 11. Figure 9 shows that the longitudinal frame 325 is on the outside of the girder 11, and the two are connected by bolts. The second transverse frame 323 is in an overall horizontal shape and extends horizontally, and the longitudinal frame 325 is in a vertical shape and extends longitudinally. Figure 10 shows that specifically, the left side is in the shape of a straight plate frame. In a top view, the left side is roughly in the shape of a Chinese character 'ri'. The right side is in the shape of a frame inclined upward to the right. The two longitudinal frames 325 are on the right side of the second transverse frame 323 and are symmetrically arranged. Preferably, the second transverse frame 323 and the longitudinal frame 325 are welded, with high structural strength. In some embodiments, a bolt connection method can also be used.

[0116] Please refer to Figure 9 , Figure 10 , Figure 11 and Figure 13In this embodiment, the fire pump 31 includes a pump housing 311 and a gearbox 312, which are bolted to a second transverse frame 323. The second transverse frame 323 serves as a bridge connecting the fire pump 31 and the longitudinal frame 325. The second transverse frame 323 is bolted to the pump housing 311 and gearbox 312 of the fire pump 31. It is also connected to the longitudinal frame 325 to form an integrated support structure. The beam 11, serving as the vehicle's main frame, provides high-strength support and structural stability. Through its connection to the longitudinal frame 325, it participates in the installation and securing of the fire pump 31.

[0117] See also Figure 11 and Figure 12 In this embodiment, the shock absorber 33 includes a second shock absorber 332. At least one second shock absorber 332 is disposed between the pump housing 311 and the second transverse frame 323. This second shock absorber 332 can directly absorb vibrations of the pump housing 311 during operation, reducing stress on the connection between the pump housing 311 and the second transverse frame 323, thereby protecting the sealing and structural integrity of the pump housing 311. The number of second shock absorbers 332 can be one, two, three, or four, depending on actual needs. An even number of second shock absorbers 332 is preferred, and these even-numbered second shock absorbers 332 are symmetrically arranged.

[0118] See also Figure 12 Specifically, the second shock absorber 332 includes a second protective plate 3321, a second shock-absorbing pad 3322, a third shock-absorbing pad 3323, and a third protective plate 3324 arranged in sequence from top to bottom. The pump casing 311 has an L-shaped first bending plate 3113. The first bending plate 3113 can be integrally formed on the pump casing 311 body, or it can be detachable from the pump casing 311 body by bolts. The first bending plate 3113 fixes the second protective plate 3321, the second shock-absorbing pad 3322, the third shock-absorbing pad 3323, the third protective plate 3324 and the second transverse frame 323 by bolts, wherein the first bending plate 3113 is located between the second shock-absorbing pad 3322 and the third shock-absorbing pad 3323. For example, by using a bolt and nut combination, the second protective plate 3321, the second shock absorbing pad 3322, the first bent plate 3113, the third shock absorbing pad 3323, the third protective plate 3324 and the second transverse frame 323 are all provided with a fourth through hole that passes through from top to bottom.

[0119] The second and third shock-absorbing pads 3322 and 3323 are made of highly elastic and durable materials, such as rubber or polyurethane, to absorb and dissipate vibration energy. The second and third protective plates 3321 and 3324 are made of metal or composite materials and have a certain degree of rigidity. They protect the second and third shock-absorbing pads 3322 and 3323 from direct contact with the external environment and also provide anchor points.

[0120] See also Figure 13 and Figure 14 In this embodiment, at least one second shock absorber 332 is provided between the gearbox 312 and the second transverse frame 323, which can effectively isolate the vibration generated by the gearbox 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 gearbox 312 from additional wear.

[0121] See also Figure 14 Specifically, the second shock absorber 332 includes a second protective plate 3321, a second shock-absorbing pad 3322, a third shock-absorbing pad 3323, and a third protective plate 3324 arranged in sequence from top to bottom. The gearbox 312 has an L-shaped second bending plate 3121. The second bending plate 3121 can be integrally formed on the housing of the gearbox 312, or can be detachable from the housing of the gearbox 312 by bolts. The second bending plate 3121 fixes the second protective plate 3321, the second shock-absorbing pad 3322, the third shock-absorbing pad 3323, the third protective plate 3324 and the second transverse frame 323 by bolts, wherein the second bending plate 3121 is located between the second shock-absorbing pad 3322 and the third shock-absorbing pad 3323.

[0122] In some embodiments, at least one second shock absorber 332 is disposed between the second transverse frame 323 and the beam 11 to absorb vibrations caused by vehicle movement and ensure stable operation of the fire pump 31. The second shock absorber 332 includes, from top to bottom, a second protective plate 3321, a second shock absorbing pad 3322, a third shock absorbing pad 3323, and a third protective plate 3324.

[0124] Preferably, the motor 34 is located between the two beams 11 to rationally utilize the space of the chassis 1.

[0125] In this embodiment, the subframe 12 is located above the beam 11 and the fire pump 31, and the fire pump 31 extends beyond the top of the beam 11. The bottom of the subframe 12 is provided with a groove to accommodate the portion of the fire pump 31 that extends beyond the beam 11. The subframe 12 can hide the fire pump 31 underneath, so that other equipment such as the drainage device 2 can be placed above the subframe 12, making full use of the vehicle's space resources. Preferably, the fire pump 31 is provided at the rear end of the beam 11, at the rear of the vehicle. The position of the subframe 12 near the rear of the vehicle is the preferred location for placing the drainage device 2.
