The seismic protection window 4 is used to protect the instrument panel of the instrument body 1. The two ends of the No. 1 seismic protection sub-bin 31 are respectively fixedly connected to the No. 1 connecting plate 311, and one side of the two ends of the No. 1 seismic protection sub-bin 31 is fixedly connected with a convex strip 312. The two ends of the No. 2 seismic protection sub-bin 32 are respectively fixedly connected with the No. 2 connecting plate 321, and one side of the two ends of the No. 2 seismic protection sub-bin 32 is provided with a groove 322. The No. 1 connecting plate 311 and the No. 2 connecting plate 321 are symmetrically provided with connecting holes 313, and the interior of the connecting hole 313 is movably penetrated with bolts. The connecting plate 311 and the second connecting plate 321 are fixedly connected by bolts, and the convex strip 312 is movably connected to the inside of the groove 322 to realize the preliminary connection between the first earthquake protection sub-bin body 31 and the second earthquake protection sub-bin body 32. The earthquake protection window 4 includes a sealing cover plate 41 and an earthquake-resistant ring 42. A plurality of mounting bolts 411 are threadedly connected to the edge of the sealing cover plate 41. A first glass plate 412 is fixedly connected to the center of the sealing cover plate 41. A plurality of movable rods 421 are fixedly connected to one side of the earthquake-resistant ring 42 in a circular arrangement. A number of cylinders 413 are fixedly installed, and a number of movable rods 421 are movably clamped in the inside of the cylinders 413 respectively. The outer sides of the movable rods 421 are movably sleeved with return springs 422, and the return springs 422 are arranged between the sealing cover plate 41 and the anti-seismic ring 42. The inner walls of the No. 1 anti-seismic protection sub-bin body 31 and the No. 2 anti-seismic protection sub-bin body 32 are fixedly connected with a number of bolt positioning plates 35, and one end of the mounting bolt 411 is threadedly connected to the inside of the bolt positioning plate 35, and the bolt positioning plate 35 is used to provide stable support for one end of the mounting bolt 411.

[0027] In this embodiment, when the shock-absorbing foam 33 needs to be replaced, first rotate and remove the mounting bolts 411, remove the sealing cover plate 41 and the anti-seismic ring 42, and then take out the aged shock-absorbing foam 33 from the anti-seismic protection chamber 3 and replace it with a new shock-absorbing foam 33, thereby ensuring that the anti-seismic protection chamber 3 can protect the instrument body 1 for a long time and extend the service life of the anti-seismic protection mechanism 2; in addition, when the anti-seismic protection chamber 3 needs to be replaced, rotate and remove the bolts between the No. 1 connecting plate 311 and the No. 2 connecting plate 321, thereby completing the disassembly and replacement of the anti-seismic protection chamber 3.

[0028] The method of use and working principle of this device: When external gravel collides with the seismic protection chamber 3, the primary function of the seismic protection chamber 3 is to build a solid protective barrier for the instrument body 1, effectively preventing the gravel from directly hitting the instrument body 1, thereby effectively avoiding the pressure instrument from malfunctioning due to such direct collision. During the collision, the impact force generated by the gravel hitting the seismic protection chamber 3 will be quickly transmitted to the internal structure of the seismic protection chamber 3. This impact force is then further transmitted to the inside of the shock-absorbing foam 33, and the shock-absorbing foam 33 works with its unique pore structure. When the impact force acts on the foam, the air in the pores is squeezed sharply. Through this physical process, the energy of the impact force is converted, part of which is converted into heat energy, and the other part is converted into the elastic potential energy of the foam itself.

[0029] At the same time, when the gravel hits the anti-seismic ring 42, the anti-seismic ring 42 plays its key role of alternative protection, directly contacting the gravel instead of the instrument body 1, thereby ensuring that the gravel does not hit the instrument panel of the instrument body 1. In this process, the movable rod 421 of the anti-seismic ring 42 will shrink into the cylinder 413 due to the impact force, and at the same time, it will squeeze the reset spring 422 and the first flexible rubber ring 424. When the impact is over, the reset spring 422 and the first flexible rubber ring 424 drive the anti-seismic ring 42 to return to the initial position by their own elastic restoring force, so as to prepare for the next possible impact.

[0030] In terms of equipment maintenance, when the shock-absorbing foam 33 needs to be replaced, the standard operating procedures should be followed first. First, rotate and remove the mounting bolts 411, and then carefully remove the sealing cover plate 41 and the anti-seismic ring 42. After that, the aged shock-absorbing foam 33 can be smoothly taken out of the anti-seismic protection chamber 3 and replaced with a brand new shock-absorbing foam 33. In addition, when the anti-seismic protection chamber 3 needs to be replaced for various reasons, the connecting bolts between the No. 1 connecting plate 311 and the No. 2 connecting plate 321 can be removed by rotating to complete the disassembly and replacement of the anti-seismic protection chamber 3. Such design and maintenance process is intended to ensure that the pressure instrument can operate continuously and stably in a complex working environment, while facilitating effective maintenance and component replacement when necessary, thereby ensuring the reliability and service life of the pressure instrument.
