DETAILED DESCRIPTION
[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] Embodiment: A vacuum pump safety protection device, such as Figure 1-Figure 4 As shown, it includes a protective box 1, a base frame 12, a cover plate 2, a vibration reduction assembly, a vacuum pump 7 and a sound insulation assembly. The base frame 12 is welded to the bottom of the protective box 1, and the cover plate 2 is slidably connected to the right part of the protective box 1. A vibration reduction assembly for reducing vibration is arranged at the bottom of the protective box 1, and a vacuum pump 7 is installed on the vibration reduction assembly by bolts. The front and rear inner walls of the protective box 1 are provided with sound insulation assemblies for blocking the noise generated during the operation of the vacuum pump 7, and through holes 21 are opened in the middle and upper parts of the cover plate 2.
[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the vibration reduction assembly includes a soft plate 3, a first fixing rod 4, a mounting plate 5 and an elastic member 6. The soft plate 3 is connected to the bottom of the protective box 1 by bolts. The soft plate 3 is made of rubber. The first fixing rods 4 are symmetrically fixed on the left and right sides of the top of the soft plate 3. The first fixing rods 4 are U-shaped and inverted and fixed to the soft plate 3. The mounting plate 5 is slidably connected between the two first fixing rods 4. The elastic member 6 is connected between the mounting plate 5 and the soft plate 3. The elastic member 6 is a vibration reduction spring, and the elastic member 6 is sleeved on the first fixing rod 4.
[0023] like Figure 1 and Figure 4 As shown, the sound insulation assembly includes a mounting frame 8, a sound insulation board 9 and a first limiting rod 10. The mounting frames 8 are welded to the inner walls on both the front and rear sides of the protection box 1. The sound insulation board 9 is slidably connected to the mounting frame 8. The first limiting rod 10 is slidably connected to the right side of the top of the mounting frame 8. The first limiting rod 10 can fix and limit the sound insulation board 9 to prevent the sound insulation board 9 from sliding out of the mounting frame 8.
[0024] When applying this embodiment, the staff places the protection box 1 on the ground, installs the vacuum pump 7 on the mounting plate 5, passes the exhaust hose through the through hole 21 opened in the middle of the baffle and connects it to the vacuum pump 7, and then starts the vacuum pump 7. The vibration generated by the vacuum pump 7 is transmitted from the mounting plate 5 to the elastic member 6. Under the elastic characteristics of the elastic member 6, the vibration transmitted from the mounting plate 5 is buffered and absorbed, and the soft plate 3 is made of rubber material, which can further reduce the conduction of vibration. The sound insulation board 9 can effectively block the noise generated by the operation of the vacuum pump 7 from being transmitted to the outside of the protection box 1. When the vacuum pump 7 or the sound insulation board 9 needs to be inspected and repaired, it is only necessary to lift the cover plate 2 upward from the right side of the protection box 1, and then pull the first limit rod 10 away from the mounting frame 8. At this time, the sound insulation board 9 can be slid off the mounting frame 8. In this way, when the vacuum pump 7 after vibration reduction and sound insulation is working, the vibration and noise generated by the vacuum pump 7 are greatly weakened, thereby not affecting the overall performance of the equipment and improving the comfort of the working environment of the staff.
[0025] like Figure 1 As shown, it also includes a second fixing rod 13 and a second limiting rod 14. The second fixing rod 13 is fixedly connected to the right side of the top of the protection box 1, and the second limiting rod 14 is slidably connected to the second fixing rod 13.
[0026] The second limiting rod 14 can be inserted into the through hole 21 formed on the upper portion of the cover plate 2, thereby fixing and limiting the cover plate and playing a locking role.
[0027] like Figure 1 As shown, a pull rod 11 is also included, and the pull rod 11 is connected to the middle of the top of the protection box 1 by bolts.
[0028] The arrangement of the pull rod 11 enables the staff to move the device more easily by hand, thereby improving the portability of the device.
[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
