According to some embodiments of the present application, optionally, the flywheel 311 of the engine 31 is connected with an input shaft of the water pump 21.

The engine 31 comprises two power outputs, on the one hand the engine 31 is connected to a hydraulic pump via a power take-off or the engine 31 is connected to a hydraulic pump, and on the other hand the flywheel 311 of the engine 31 is connected to the input shaft of the water pump 21. In some embodiments, the engine flywheel 311 is rigidly connected to the input shaft of the water pump 21.

The conventional engine 31 is in transmission connection with the water pump 21 through a clutch, and when the transmission is performed through the clutch, the clutch as an intermediate transmission member causes torque loss, so that the transmission efficiency is reduced. Thus, the elimination of a clutch as an intermediate transmission makes it possible on the one hand to increase the transmission efficiency and on the other hand to save space.

According to some embodiments of the present application, optionally, as shown in fig. 2 to 4, the power mechanism 3 further includes a coupling 32, and the flywheel 311 of the engine 31 is connected with the input shaft of the water pump 21 through the coupling 32.

The coupling 32 serves as a mechanical part for firmly coupling the driving and driven shafts of the various mechanisms together for rotation and for transmitting motion and torque. For better transmission of torque and axial forces, the coupling 32 is provided as an interference connection with the input shaft of the water pump 21.

According to some embodiments of the present application, optionally, as shown in fig. 2 to 4, one end of the coupling 32 is connected to the flywheel 311 of the engine 31 by the first fastener 33, and the other end of the coupling 32 is keyed to the input shaft of the water pump 21.

The first fastening member 33 can be a bolt, a screw, or the like, and the annular arrangement of the first fastening member 33 fixes the coupling 32 and the flywheel 311. Specifically, a threaded hole is formed in the flywheel 311, and the first fastening member 33 on the coupling 32 is engaged with the threaded hole. The other end of shaft coupling 32 is connected with water pump 21's input shaft key, and the key-type connection can be spline or flat key connection to the flat key is connected as an example, is equipped with first keyway on shaft coupling 32, also is equipped with the second keyway on water pump 21's the input shaft, is provided with the flat key on the second keyway, and the flat key is the same with first keyway size, and the cooperation through flat key and first keyway is connected the other end of shaft coupling 32 with water pump 21's input shaft. In some embodiments, the other end of the coupling 32 may also be connected to the input shaft of the water pump 21 via a flange (the flange being a component of the interconnection between the shaft and the hub). The working principle is as follows: when the water pump 21 needs to be operated, the flywheel 311 starts to operate after the engine 31 is started. Since the engine 31 and the coupling 32 are fixed by the first fastening member 33, the coupling 32 is operated simultaneously when the flywheel 311 rotates, and then the water pump 21 is driven to operate by the flange.

According to some embodiments of the present application, optionally, as shown in fig. 2 to 4, the engine 31 further includes a flywheel housing 312, and the flywheel housing 312 covers the flywheel 311.

Since the flywheel 311 is directly connected to the input shaft of the water pump 21, the entire structure is exposed to the air, and dust may enter the inside of the flywheel 311 over a long period of time, resulting in a malfunction of the flywheel 311. Therefore, a flywheel housing 312 is provided outside the flywheel 311, and the flywheel housing 312 covers the flywheel 311. The flywheel housing 312 is adapted to the shape of the housing of the engine 31 and is fixed at the periphery by a circumferential bolt.

By arranging the flywheel housing 312, dust is prevented from entering the flywheel 311, and the normal operation of the flywheel 311 is ensured.

According to some embodiments of the present application, optionally, as shown in fig. 3 and 4, the water pump 21 includes a connection housing 211, the connection housing 211 being provided at an input shaft of the water pump 21; a transition sleeve is arranged between the flywheel housing 312 and the connecting housing 211 and is connected with the connecting housing 211 through a second fastener 212, and the transition sleeve is used for adjusting the installation position between the flywheel housing 312 and the connecting housing 211.

Similarly, in order to protect the normal operation of the water pump 21, a connection housing 211 is provided at the input shaft of the water pump 21. The connecting housing 211 is connected with the flywheel housing 312 through a second fastening member 212 arranged in a ring shape. The second fastener 212 may be a bolt, screw, or the like. In some embodiments, the surface of the flywheel 311 connected to the coupling 32 is a coupling surface of the flywheel 311, the distance between the coupling surface of the flywheel 311 and the flywheel housing 312 is a first distance, the surface of the coupling 32 connected to the flywheel 311 is a coupling surface of the coupling 32, and the distance between the coupling surface of the coupling 32 and the coupling housing 211 is a second distance. Since the flywheel housing 312 is typically of a standard size, the second pitch is greater than the first pitch. Accordingly, when the flywheel 311 and the water pump 21 are connected by the coupling 32, there is a dimensional difference, and a gap between the connection housing 211 and the flywheel housing 312 cannot be completely attached. Therefore, in order to eliminate the size difference, a transition sleeve (not shown) is provided between the flywheel housing 312 and the connection housing 211. The thickness of the transition sleeve is just the difference between the second spacing and the first spacing. In other embodiments, the size difference may also be eliminated by customizing the flywheel housing 312 such that the first spacing is equal to the second spacing.

The size difference is eliminated by arranging the transition sleeve, and the mounting position between the flywheel housing 312 and the connecting housing 211 is adjusted.

According to some embodiments of the present application, optionally, the flywheel 311 of the engine 31 is keyed to the input shaft of the water pump 21.

The flywheel 311 of the engine 31 and the input shaft of the water pump 21 can be directly connected by a key, which is to realize circumferential fixation between the shaft and parts on the shaft by the key so as to transmit motion and torque. Specifically, a key may be disposed on the input shaft of the water pump 21, a key slot corresponding to the key is disposed on the flywheel 311 of the engine 31, and the key slot is matched with the key to connect the flywheel 311 and the water pump 21. The torque of the flywheel 311 can be transmitted to the water pump 21 by key connection.

According to some embodiments of the present application, optionally, the flywheel 311 of the engine 31 is in meshed connection with the input shaft of the water pump 21.

Engagement refers to a driving relationship between two mechanical parts, called engagement drive. The motion and power of the driving wheel (shaft) are transmitted to the driven wheel (shaft) through the meshing action of the gears, and the required rotating speed and torque are obtained. The flywheel 311 of the engine 31 is a driving wheel, the input shaft of the water pump 21 is a driven shaft, the flywheel 311 of the engine 31 is meshed with the input shaft of the water pump 21 through a gear, power is transmitted to the input shaft of the water pump 21, and the input shaft of the water pump 21 obtains required rotating speed and torque. By means of the meshing engagement, the torque of the flywheel 311 can be better transmitted to the water pump 21.

In some embodiments according to the application, optionally, as shown in fig. 5, the mobile pump station further includes a housing 4, the housing 4 is disposed on the traveling mechanism 1, the housing 4 is used for housing the power mechanism 3 and the drainage mechanism 2, and the housing 4 has an opening 41 for protruding the water inlet 22 and the water outlet 23.

In order to protect the power mechanism 3 and the drainage mechanism 2 which are arranged on the travelling mechanism 1, a shell 4 is also arranged on the travelling mechanism 1, and the shell 4 covers the power mechanism 3 and the drainage mechanism 2. In addition, since the water inlet 22 and the water outlet 23 of the drainage mechanism 2 need to be drained accordingly, the housing 4 needs to have an opening 41 through which the water inlet 22 and the water outlet 23 protrude. The position and size of the opening 41 depend on the position and size of the water inlet 22 and the water outlet 23.

Through setting up casing 4, prevent that power unit 3 and drainage mechanism 2 from receiving external environment influence, play the guard action.
