There are stepped surfaces at the upper ends of the chassis and the front cover. The upper cover is installed on the stepped surfaces of the chassis and the front cover by bolts. Spacer block A is in a "cross" shape structure. Spacer block A is arranged in the middle under the motor. The longitudinal section of spacer block B is in an L shape. The number of spacer block B is 4 and they are circumferentially arranged at the four corners of the lower end of the motor. The small hole of the tapered hole is located inside the chassis and the large hole is located outside the chassis. The diameter value of the large hole of the tapered hole is twice the diameter value of the small hole. There are 4 groups of tapered holes on each of the 3 sides of the chassis. 2 groups of tapered holes are located in the upper part of the side, and 2 groups of tapered holes are located in the middle of the side. The 2 groups of upper tapered holes are symmetrically arranged on the side of the chassis. Each of the 2 groups of upper tapered holes has 9 tapered holes and is arranged in a nine-square grid.

[0007] The length and width values of the water tank are equal to the length and width values of the motor respectively, and the height value of the liquid water in the water tank is 3 / 5 of the height value of the water tank; the number of springs and dampers at the bottom of the chassis is 4 and they are evenly distributed between the cushion blocks A and B, and the number of springs and dampers on the side of the chassis is 2 and they are symmetrically arranged in the middle of the side of the chassis; each side of the motor is respectively provided with 4 buffer blocks and they are evenly distributed at the four corners. The lower part of the buffer block is a stepped cylinder, and the upper part of the buffer block is provided with rubber strip A and rubber strip B. Rubber strip A and rubber strip B are staggered and arranged at equal intervals. From the center to the outside of the upper part of the buffer block, there is 1 rubber strip A, 4 circumferentially arranged rubber strip Bs, and 8 circumferentially arranged rubber strip As in sequence. The length value of rubber strip A is 2 times the length value of rubber strip B. The lower part of the buffer block is installed on the side of the chassis and the lower part of the buffer block contacts the motor; the support plate C is an arc-shaped structure and is concentrically fitted with the buffer block.

[0008] The pump base is welded on the outer side surface of the chassis. The longitudinal sections of the pump base and the cushion block C are in an L shape. There are round holes in the middle of the pump base and the cushion block C, and the lower main pipe of the pressure pump passes through the round holes of the pump base and the cushion block C.

[0009] The present invention is respectively provided with tapered holes on the front, rear and left side panels of the chassis, and the small holes of the tapered holes are located inside the chassis and the large holes are located outside the chassis. Through this design, air cooling is realized for the motor, that is, when the flowing air outside blows towards the motor through the tapered holes, air flow pressurization and low temperature are realized, so that this pressurized and low-temperature air flow cools the motor by air cooling.

[0010] The present invention is provided with cushion blocks A and B between the motor and the bottom of the chassis. Through cushion blocks A and B, the motor can be supported, and at the same time, the rubber cushion blocks A and B can buffer the vibration of the motor, reducing the vibration of the motor and eliminating the transmission of the motor vibration energy to the chassis.

[0011] The present invention installs a water tank with liquid water above the motor. Through this design, vibration control of the motor is realized, that is, the vibration energy of the motor is transmitted to the liquid water through the water tank. The vibration energy of the motor causes the liquid water in the water tank to fluctuate. The kinetic energy transmitted by the motor is converted into the internal energy of the liquid water through the fluctuation of the liquid water and consumed, thereby reducing the vibration of the motor; in addition, the liquid water in the water tank can also absorb the heat energy above the motor to realize cooling of the motor.

[0012] The present invention installs springs and dampers between the chassis and the motor. Through this design, vibration reduction of the motor is realized, that is, the vibration energy of the motor is converted into the elastic potential energy of the spring through the elastic deformation of the spring and consumed, and the elastic potential energy of the spring is quickly consumed by the damper, so that the spring and the motor on it quickly become stable, preventing the spring from driving the motor on it to continuously reciprocate.

[0013] The present invention is provided with a buffer block on the side of the motor. The buffer block can not only prevent the motor from colliding with the chassis and the front cover during vibration, but also absorb the vibration energy through the buffer block made of rubber material. In addition, the rubber strip A and the rubber strip B on the buffer block can achieve secondary buffering of the motor. That is, when the motor vibrates and displaces, it will first compress the rubber strip A, converting the vibration energy of the motor into the elastic potential energy of the rubber strip A, causing the rubber strip A to deform, and achieving primary buffering and vibration reduction of the motor. When the motor continues to compress the rubber strip A, it will contact the rubber strip B, causing the rubber strip B to undergo elastic deformation, thereby achieving secondary buffering and vibration reduction of the motor.

[0014] The present invention is provided with a cushion block C under the pressure pump to reduce the vibration of the pressure pump through the cushion block C.

[0015] The present invention is provided with a main pipe and a branch pipe at the pressure pump, and the diameter value of the main pipe is set to be twice the diameter value of the branch pipe. This design enables the liquid water flowing through the main pipe to be pressurized when flowing, and the liquid water in the branch pipe on the side of the motor flows normally.

[0016] The present invention arranges the branch pipe in a bent shape on the side of the motor and in an M shape. This design can not only cool the motor through the liquid water in the branch pipe, but also increase the flow path of the liquid water in the branch pipe through the bent and M-shaped arrangement of the branch pipe, enabling the liquid water to stay on the side of the motor for a longer time for sufficient heat exchange. And this bent design can also fit the motor over a large area to achieve large-area heat exchange, improve the heat exchange efficiency, and quickly cool the motor. In addition, the liquid water in the branch pipe can also absorb the vibration energy of the motor to play a role in vibration reduction, and the vibration of the motor can also promote the fluctuation of the liquid water in the branch pipe, causing the liquid water to generate turbulence, and promoting the heat exchange between the liquid water in the branch pipe and the motor.

[0017] The beneficial effects of the present invention are as follows: The motor is cooled by air through the conical holes in the chassis and the front cover, the vibration control and cooling of the motor are achieved through the liquid water in the water tank on the motor, the vibration reduction of the motor is achieved through the springs and dampers between the chassis and the motor, the secondary buffering and vibration reduction of the motor are achieved through the buffer block provided on the side of the motor, and the cooling and vibration reduction of the motor are achieved through the bent branch pipe on the side of the motor.

[0032] Combined Figure 4 As shown, the vibration damping device includes a water tank 13, a spring 2, a damper 4, and a buffer block 17. The upper end of the water tank 13 is installed on the lower end surface of the upper cover 16 through bolts 12. The lower end of the water tank 13 is placed on the upper end surface of the motor 1.

[0033] In the present invention, a water tank 13 with liquid water 15 is installed above the motor 1. Through this design, the vibration control of the motor 1 is realized, that is, the vibration energy of the motor 1 is transmitted to the liquid water 15 through the water tank 13. The vibration energy of the motor 1 causes the liquid water in the water tank 13 to fluctuate. Through the fluctuation of the liquid water 15, the kinetic energy transmitted by the motor 1 is converted into the internal energy of the liquid water 15 and consumed, thereby reducing the vibration of the motor 1; in addition, the liquid water 15 in the water tank 13 can also absorb the heat energy above the motor 1 to realize the cooling of the motor 1.

[0034] In the present invention, a spring 2 and a damper 4 are installed between the chassis 6 and the motor 1.

[0035] In the present invention, a buffer block 17 is provided on the side of the motor 1. Through the buffer block 17, it can not only prevent the motor 1 from colliding with the chassis 6 and the front cover 18 during vibration, but also absorb the vibration energy through the buffer block 17 made of rubber; in addition, the rubber strips A19 and rubber strips B23 on the buffer block 17 can realize the secondary buffering of the motor 1, that is, when the motor 1 vibrates and displaces, it will first compress the rubber strip A19, convert the vibration energy of the motor 1 into the elastic potential energy of the rubber strip A19, and cause the rubber strip A19 to deform to realize the primary buffer and vibration damping of the motor 1. When the motor 1 continues to compress the rubber strip A19, it will contact the rubber strip B23, causing the rubber strip B23 to deform elastically, thereby realizing the secondary buffer and vibration damping of the motor 1.

[0036] Combined Figure 5As shown in the figure, the cooling device is composed of a pressure pump 10, a main pipe 7 and a branch pipe 20. The pressure pump 10 is installed outside the chassis 6 through a cushion block C9 and a pump base 8. The main pipes 7 are respectively arranged at the upper and lower ends of the pressure pump 10.

The support rod 14 is welded to the lower end face of the upper cover 16. The diameter value of the main pipe 7 is twice that of the branch pipe 20. The branch pipe 20 is bent and arranged on the side of the motor 1 in an M shape.

[0037] In the present invention, a cushion block C9 is provided under the pressure pump 10 to reduce the vibration of the pressure pump 10 through the cushion block C9.

[0038] In the present invention, the main pipe 7 and the branch pipe 20 are provided at the pressure pump 10, and the diameter value of the main pipe 7 is set to be twice that of the branch pipe 20. This design enables the liquid water 15 to flow under pressure when flowing through the main pipe 7, and the liquid water 15 in the branch pipe 20 on the side of the motor 1 to flow normally.

[0039] In the present invention, the branch pipe 20 is bent and arranged on the side of the motor 1 in an M shape. This design can not only cool the motor 1 through the liquid water 15 in the branch pipe 20, but also increase the flow path of the liquid water 15 in the branch pipe 20 through the bent and M-shaped arrangement of the branch pipe 20, so that the liquid water 15 stays longer on the side of the motor 1 for sufficient heat exchange. Moreover, this bent design can also fit the motor 1 over a large area to achieve large-area heat exchange, improve the heat exchange efficiency and quickly cool the motor 1. In addition, the liquid water in the branch pipe 20 can also absorb the vibration energy of the motor 1 to play a role in vibration reduction, and the vibration of the motor 1 can also promote the fluctuation of the liquid water 15 in the branch pipe 20 to generate turbulence in the liquid water 15, promoting the heat exchange between the liquid water 15 in the branch pipe 20 and the motor 1.
