[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides an adjustable vibration isolation device for a horizontal water pump, including a base 1, a support frame 5 fixedly installed on the top of the base 1, several sets of vibration dampers 6 installed on the top of the support frame 5, a vibration isolation plate 7 installed on the top of the several sets of vibration dampers 6, and an adjustment component 8 installed at the bottom of the vibration isolation plate 7. The adjustment component 8 includes a fixed plate 81 fixedly installed on the top of the base 1, a screw 82 fixedly installed on the top of the fixed plate 81, a movable plate 83 movably fitted on the outer arc surface of the screw 82, a nut 84 threadedly connected to the outer side of the screw 82, and the bottom of the nut 84 fitting against the top of the movable plate 83. Two sets of connecting rods 87 are symmetrically fixedly installed on the top of the movable plate 83, one end of each set of connecting rods 87 movably extends through to the top of the support frame 5, and one end of each set of connecting rods 87 is fixedly installed at the bottom of the vibration isolation plate 7.

[0025] In use, by adjusting the settings of component 8, and utilizing the connection relationship between screw 82, moving plate 83, nut 84, connecting rod 87 and vibration isolation plate 7, rotating nut 84 moves on screw 82 while simultaneously moving moving plate 83. Depending on the direction of rotation of nut 84, when nut 84 moves downward, it moves moving plate 83 downward; when nut 84 moves upward, moving plate 83 moves upward under the push of vibration damper 6. Simultaneously, the up-and-down movement of moving plate 83 drives vibration isolation plate 7 to move up and down via connecting rod 87. The distance between vibration isolation plate 7 and support frame 5 changes accordingly, and the damping coefficient of multiple sets of vibration dampers 6 located between vibration isolation plate 7 and support frame 5 changes, thereby achieving the effect of adjusting the vibration damping force.

[0026] A rubber pad 2 is fixedly installed at the bottom of the base 1. A set of mounting holes 3 are opened through the four corners of the base 1 and the rubber pad 2. A set of fixing bolts 4 are installed inside the four sets of mounting holes 3. The setting of the rubber pad 2 further improves the vibration isolation effect. The mounting holes 3 and fixing bolts 4 are used to fix the vibration isolation device.

[0027] The vibration damper 6 includes a damping rod 61. The bottom of the damping rod 61 is fixedly installed on the top of the support frame 5, and the top of the damping rod 61 is fixedly installed on the bottom of the vibration isolation plate 7. A spring 62 is fitted on the outside of the damping rod 61. The vibration reduction effect is achieved through the connection between the damping rod 61 and the spring 62.

[0028] One end of the spring 62 is fixedly welded to the upper outer part of the damping rod 61, and the other end of the spring 62 is fixedly welded to the lower outer part of the damping rod 61. The connection between the damping rod 61 and the spring 62 improves the stability of the spring 62 during operation.

[0029] A first limiting plate 85 is fixedly installed in the middle of the screw 82, and a second limiting plate 86 is fixedly installed in the top of the screw 82. The movable plate 83 is located between the first limiting plate 85 and the second limiting plate 86. Through the connection relationship between the first limiting plate 85, the second limiting plate 86, the screw 82 and the movable plate 83, the range of vertical movement of the movable plate 83 is limited, so as to avoid the movement distance being too large and affecting the use effect of the shock absorber 6.

[0030] Two sets of limiting rods 9 are fixedly installed on the top of the support frame 5. One end of each set of limiting rods 9 extends movably through to the top of the vibration isolation plate 7, and a third limiting plate 10 is fixedly installed on one end of each set of limiting rods 9. By setting the limiting rods 9, the vibration isolation plate 7 can move up and down along the outer arc surface of the limiting rods 9, thus preventing the vibration isolation plate 7 from moving in the horizontal direction. At the same time, by setting the third limiting plate 10, the vibration isolation plate 7 is prevented from slipping off the outer arc surface of the limiting rods 9.

[0031] A mounting plate 11 is fixedly bolted to the top of the vibration isolation plate 7, and a water pump body 12 is mounted on the top of the mounting plate 11. The installation of the water pump body 12 is achieved through the setting of the vibration isolation plate 7 and the mounting plate 11.

[0032] In practical use: The vibration isolation device is fixedly installed in the designated position through the mounting holes 3 of the base 1 using fixing bolts 4. Then, the water pump body 12 is bolted to the top of the vibration isolation plate 7 through the mounting plate 11. The vibration damper 6 and the adjustment component 8 work together to achieve the vibration reduction effect of the water pump body 12. During the vibration of the water pump body 12, when the vibration isolation amplitude is found to be too large or too small, the nut 84 is rotated and moves on the screw 82, driving the moving plate 83 to move. Depending on the direction of rotation of the nut 84, when the nut 84 moves downward, it drives the moving plate 83 to move downward. When the nut 84 moves upward, the moving plate 83 moves upward under the push of the vibration damper 6. The up and down movement of the moving plate 83 drives the vibration isolation plate 7 to move up and down through the connecting rod 87. The distance between the vibration isolation plate 7 and the support frame 5 changes accordingly. At the same time, the damping coefficient of the multiple sets of vibration dampers 6 between the vibration isolation plate 7 and the support frame 5 changes, achieving the effect of adjusting the vibration damper 6. Through the above device, the efficiency of the vibration isolation device is improved.

[0033] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
