[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 and Figure 4 As shown, in this embodiment, a fixed frame for a vacuum water diversion device includes a longitudinal bracket 1, and the number of longitudinal brackets 1 is provided. The bottom ends of the two longitudinal brackets 1 are fixedly connected to a shock-absorbing assembly 2; the shock-absorbing assembly 2 includes a connecting plate 201, the bottom end of the connecting plate 201 is fixedly connected to a piston rod 202, the bottom end of the piston rod 202 is fixedly connected to a damping piston 203, the outside of the damping piston 203 is provided with a cylinder body 204, the inside of the cylinder body 204 is slidably connected to a floating piston 205, the surface of the piston rod 202 is movably sleeved with a shock-absorbing spring 206, and the bottom end of the cylinder body 204 is fixedly connected to a supporting bottom plate 207.

[0022] When the vacuum water diversion device generates vibration during operation, the longitudinal bracket 1 squeezes the piston rod 202 downward, causing the damping piston 203 to slide in the cylinder 204. At the same time, the shock-absorbing spring 206 is squeezed and contracted. As the damping piston 203 moves downward, pressure is generated below it, and the damping oil below it flows to the top of the damping piston 203 through the piston valve. The movement of the damping oil slows down the compression stroke of the shock-absorbing spring 206. At the same time, the high-pressure nitrogen in the air cavity plays a certain buffering role, thereby improving the overall shock absorption effect.

[0023] There are two connecting plates 201. The two connecting plates 201 are located on both sides of the longitudinal bracket 1. The floating piston 205 is located below the damping piston 203. The top of the floating piston 205 and the cylinder block 204 form an oil chamber, and damping oil is provided inside the oil chamber. The bottom of the floating piston 205 and the cylinder block 204 form an air chamber, and high-pressure nitrogen is provided inside the air chamber.

[0024] Rubber gaskets 3 are provided on one side of the longitudinal brackets 1 close to each other. A transverse bracket 4 is provided on the side of the rubber gasket 3 away from the longitudinal bracket 1. A first screw 5 is slidably connected inside the transverse bracket 4. A first nut 6 is threadedly connected to the surface of the first screw 5. A lifting lug 7 is fixedly connected to the top end of the longitudinal bracket 1.

[0025] By placing the rubber gasket 3 between the longitudinal bracket 1 and the transverse bracket 4 and fixing its position by using the first screw 5 and the first nut 6, the assembly of the fixed frame is completed. The fixed frame adopts a split structure, which is convenient for the overall installation and disassembly, and a rubber gasket 3 is added at the connection to improve the sealing performance after assembly. The longitudinal bracket 1 and the transverse bracket 4 respectively adopt a rectangular steel pipe structure and a U-shaped structure, reducing the overall weight of the fixed frame and lowering the manufacturing cost at the same time.

[0026] There are two transverse brackets 4. The two transverse brackets 4 adopt a U-shaped structure. The first nut 6 is located inside the longitudinal bracket 1.

[0027] An angle steel 8 is provided between the transverse bracket 4 and the longitudinal bracket 1. A second screw 9 is slidably connected inside the angle steel 8. A second nut 10 is threadedly connected to the surface of the second screw 9. A third screw 11 is slidably connected inside the angle steel 8. A third nut 12 is threadedly connected to the surface of the third screw 11.

[0028] By placing the angle steel 8 at the angle between the transverse bracket 4 and the longitudinal bracket 1 and fixing the position of the angle steel 8 and the transverse bracket 4 by using the second screw 9 and the second nut 10, and fixing the position of the angle steel 8 and the longitudinal bracket 1 by using the third screw 11 and the third nut 12, the connection between the longitudinal bracket 1 and the transverse bracket 4 is strengthened, improving the stability effect of the fixed frame.

[0029] An installation hole 13 is opened at the top of the transverse bracket 4. A connecting spring 14 is fixedly connected to the inner wall of the transverse bracket 4. The top end of the connecting spring 14 is fixedly connected to a positioning block 15. A pin 16 is slidably connected inside the positioning block  15. An adjusting plate 17 is slidably connected to the surface of the transverse bracket 4. A positioning hole 18 is opened at the top of the adjusting plate 17. A moving bracket 19 is fixedly connected to the side of the adjusting plate 17 away from the transverse bracket 4.

[0030] By moving the adjustment plate 17, it drives the movable bracket 19 to slide in the horizontal bracket 4. After the position is appropriate, the positioning block 15 is stuck in the positioning hole 18 under the elastic force of the connecting spring 14, and the position of the positioning block 15 is fixed by the pin 16, thereby changing the position of the movable bracket 19 to adapt to devices of different sizes.

[0031] There are multiple mounting holes 13 , and the multiple mounting holes 13 are adapted to the positioning blocks 15 . The positioning blocks 15 are located inside the positioning holes 18 , and the movable bracket 19 adopts an I-shaped structure.

[0032] The utility model provides a fixed frame for a vacuum water diversion device, and the specific working principle is as follows:

[0033] When in use, place the rubber gasket 3 between the longitudinal bracket 1 and the transverse bracket 4, and fix its position with the first screw 5 and the first nut 6 to complete the assembly of the fixed frame, place the angle steel 8 at the angle between the transverse bracket 4 and the longitudinal bracket 1, and fix the position of the angle steel 8 and the transverse bracket 4 with the second screw 9 and the second nut 10, and fix the position of the angle steel 8 and the longitudinal bracket 1 with the third screw 11 and the third nut 12, so as to reinforce the connection between the longitudinal bracket 1 and the transverse bracket 4, move the adjustment plate 17 to drive the movable bracket 19 to slide in the transverse bracket 4, and when the position is appropriate, the positioning block 15 is moved under the elastic force of the connecting spring 14. It is stuck in the positioning hole 18, and the position of the positioning block 15 is fixed by the pin 16, so that the position of the movable bracket 19 can be changed to adapt to devices of different sizes. When the vacuum water diversion device is working and generating vibration, the longitudinal bracket 1 squeezes the piston rod 202 downward, causing the damping piston 203 to slide in the cylinder 204. At the same time, the shock-absorbing spring 206 is squeezed and contracted. As the damping piston 203 moves downward, pressure is generated below it, and the damping oil below it flows to the top of the damping piston 203 through the piston valve. The compression stroke of the shock-absorbing spring 206 is slowed down by the movement of the damping oil. At the same time, the high-pressure nitrogen in the air cavity plays a certain buffering role, thereby improving the overall shock absorption effect.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
