[0020] The detailed working process of this embodiment is as follows: the first housing 1 and the second housing 101 are detachably connected to facilitate disassembly and installation.

[0021] Through the cooperation of the shock absorption system and the shock absorption component, the vibration generated by the operation of the pump group can be reduced to the greatest extent. First, the first shell 1 and the second shell 101 are installed on the hull base, and then the pump group body 100 is installed on the corresponding shock absorption parts in the shell. The two groups of shock absorption parts are used to buffer the vibration generated by the operation of the pump group and reduce its vibration. Then, the transverse shock absorption pad 3 and the longitudinal shock absorption pad 2 are used to absorb the energy after the vibration is reduced, and the vibration generated when the pump group is working is further reduced, making the pump group more stable when working and reducing the impact on the hull and various equipment inside the hull.

[0022] like Figure 3 As shown, each shock absorbing member includes multiple groups of shock absorbers 6 and a first mounting plate 401 and a second mounting plate 402 arranged on the top of the corresponding shock absorber 6. The first mounting plate 401 is used to install the pump group body 100.

[0023] The detailed working process of this embodiment is as follows: multiple groups of shock absorbers 6 are arranged under the first mounting plate 401 and the second mounting plate 402 to form two shock-absorbing layers to reduce the vibration of the pump group body 100. The shock absorber 6 can use its own elastic characteristics or damping effect to effectively absorb and dissipate the vibration energy generated by the pump group during operation, which can significantly reduce the vibration level and protect the stability of the pump body and the pump station system.

[0024] like Figure 2 and Figure 3As shown, a second cavity 501 is formed between the mounting frame 4 and the second mounting plate 402, a third cavity 502 is formed between the first mounting plate 401 and the second mounting plate 402, the transverse shock-absorbing rubber pad 3 is located in the first cavity 5, and the two longitudinal shock-absorbing rubber pads 2 are respectively located in the second cavity 501 and the third cavity 502, wherein channels 203 are provided on the first mounting plate 401, the second mounting plate 402, the two longitudinal shock-absorbing rubber pads 2 and the transverse shock-absorbing rubber pad 3, and the axis of each channel 203 is centered.

[0025] The detailed working process of this embodiment is as follows: the longitudinal shock-absorbing rubber pad 2 can effectively absorb and dissipate the longitudinal vibration energy generated by the equipment or structure during operation, reduce the vibration amplitude and frequency, and thus protect the equipment or structure from vibration damage. The longitudinal shock-absorbing rubber pad 2 is located between the first mounting plate 401 and the second mounting plate 402 and between the mounting frame 4 and the second mounting plate 402. When the pump group vibrates during operation, the shock absorbers 6 work to reduce the vibration. The shock absorbers 6 move up and down while absorbing the vibration. At this time, the longitudinal shock-absorbing rubber pad 2 can absorb the energy generated by the up and down movement, reduce the amplitude of the up and down movement, and also absorb part of the noise generated by the vibration. The transverse shock-absorbing rubber pad 3 can effectively absorb and dissipate the transverse vibration energy generated by the equipment or structure during operation, thereby significantly reducing the vibration amplitude and frequency. The transverse shock-absorbing rubber pad 3 is located between the mounting frame 4 and the first shell 1 and the second shell 101. When the pump group vibrates left and right during operation, the transverse shock-absorbing rubber pad 3 is set to absorb the transverse energy, reduce the left and right and front and back vibration amplitudes, and absorb part of the noise generated by the vibration. The pump assembly body 100 is mounted on the first mounting plate 401 , and the output end of the pump assembly body 100 is connected to a corresponding device through a channel 203 .

[0027] The detailed working process of this embodiment is as follows: the through hole 201 is used to place the shock absorber 6, and the buffer groove 202 helps to absorb the energy generated by external impact and reduce the impact of vibration on the equipment or structure, so as to effectively absorb and disperse the impact energy and protect the components from pressure.

[0028] like Figure 2 As shown, multiple groups of buffer holes 301 are evenly distributed on the transverse shock-absorbing rubber pad 3.

[0029] The detailed working process of this embodiment is as follows: the buffer hole 301 helps to absorb the energy generated by external impact and reduce the impact of vibration on the equipment or structure, so as to effectively absorb and disperse the impact energy and protect the components from pressure.

[0030] like Figure 2As shown, the first housing 1 and the second housing 101 are both provided with connecting seats 102 , and the corresponding connecting seats 102 are connected by bolts 106 .

[0031] The detailed working process of this embodiment is as follows: the first housing 1 and the second housing 101 are connected by bolts 106 to ensure that they will not move relative to each other or separate during operation. At the same time, they can also be disassembled, which is convenient and practical.

[0032] like Figure 2 As shown, a connecting plate 105 is provided at one end of the first housing 1 close to the second housing 101 , and a connecting groove 104 is opened at one end of the second housing 101 close to the first housing 1 , and the connecting plate 105 is inserted into the corresponding connecting groove 104 .

[0033] The detailed working process of this embodiment is as follows: when the connecting groove 104 and the connecting plate 105 are at the bottom, the connection stability between the first housing 1 and the second housing 101 can be enhanced to avoid displacement during the working process.

[0034] like Figure 1 As shown, a mounting base 103 is provided on both the first housing 1 and the second housing 101 .

[0035] The detailed working process of this embodiment is as follows: the function of the mounting base 103 is to connect with the hull base and to mount the shell on the hull base.

[0036] The implementation principle of the embodiment of the present application is: first, the shock absorption system and the shock absorption component are installed in the shell, and then the shell is installed on the hull base, and then the pump group is installed on the first mounting plate 401.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting.
