In this embodiment, the outer wall of shell 11 is equipped with a plurality of lock posts that take the screw thread, is equipped with the lockhole that corresponds with the lock post on top cap 12, wears to establish lockhole, lock post through the bolt and makes top cap 12 and shell 11 fixed.

The geomagnetic monitoring electronic element comprises a solar panel 100, a PCB main board 200, a battery 300 and the like which are sequentially arranged in the inner shell 31; wherein the solar panel 100 is adhered to the inner wall of the inner casing 31; the PCB main board 200 is fixed to the inner wall of the inner casing 31 by screws and spaced apart from the solar panel 100; the battery 300 is electrically connected to the PCB main board 200 for providing power support.

Through set gradually inner shell 31, mesochite 21 and shell 11 in earth magnetism monitoring electronic component outside, realize the protection that earth magnetism monitoring electronic component is tighter, through the waterproof performance of the stable promotion earth's surface monitoring devices product of such secondary waterproof design.

Optionally, the inner shell 31 is a hollow cylindrical structure with two open ends, and the inner shell 31 and the middle shell 21 are coaxially arranged, which can be understood that the inner shell 31, the middle shell 21 and the outer shell 11 are all coaxially arranged; by such a design, not only the installation of the inner shell 31 and the middle shell 21 in the outer shell 11 is facilitated, but also the compactness of the product is further ensured while the precision is ensured.

In this embodiment, a first fixing portion 32 is disposed at one end of the inner casing 31, and a detachable bottom cover 33 is disposed at the other end; the middle shell 21 is a hollow cylindrical structure with one open end; in this way, both the bottom cover 33 and the inner shell 31 can be placed in the middle shell 21 with a hollow structure, and the outer edge of the open end of the middle shell 21 is provided with the second fixing portion 22, and the first fixing portion 32 is connected and fixed with the second fixing portion 22 so that the middle shell 21 and the inner shell 31 are sleeved and arranged.

It can be understood that, after the bottom cover 33 and the inner shell 31 are installed in the middle shell 21, in order to ensure the stability of the connection of the inner shell 31 and the middle shell 21, the fixation of the inner shell 31 and the middle shell 21 is achieved by the cooperation between the first fixing portions 32 and the second fixing portions 22.

In this embodiment, the first fixing portion 32 is a flange-disc-shaped structure, a plurality of through holes are formed in the first fixing portion 32, and a plurality of trepanning corresponding to the through holes are formed in the second fixing portion 22, and a nut is sleeved in each trepanning; the first fixing portion 32 and the second fixing portion 22 are stably fixed by a bolt connection (a bolt passes through the through hole so that the threaded portion of the bolt is screwed with the nut in the sleeve hole).

In this embodiment, a sealing rubber ring is disposed between the inner shell 31 and the bottom cover 33; a sealing rubber sleeve is sleeved between the middle shell 21 and the inner shell 31 which are connected in a sleeved mode; through setting up sealed rubber ring and sealed gum cover in order to carry out one step promotion water-proof effects, guarantee the waterproof performance of whole product.

In this embodiment, the pressure resistance of the surface monitoring device product is realized by the elastic movable connection between the middle casing 21 and the outer casing 11, that is, the middle casing 21 and the outer casing 11 are ensured to be elastically connected in the axial direction, so that certain elastic buffering is provided when the surface monitoring device bears pressure, and the hard contact between the middle casing 21 and the outer casing is avoided.

Specifically, the present embodiment further designs a buffer structure on the structure of the second fixing portion 22, that is, the second fixing portion 22 is designed as a circular ring structure, and the circular ring structure protrudes outward relative to the outer wall of the middle shell 21; a spring 40 is fitted over the middle case 21, and one end of the spring 40 abuts against the lower end surface of the second fixing portion 22 and the other end abuts against the bottom surface of the housing 11.

The spring 40 provides elastic force, elastic buffering between the middle shell 21 and the outer shell 11 is achieved, namely when the middle shell 21 moves on a stress bearing axis, the spring 40 is compressed under the action of the second fixing portion 22, and accordingly reverse buffering force is given to the second fixing portion 22, instant contact collision between the middle shell 21 and the outer shell 11 can be effectively avoided under the action of the spring 40, and the pressure resistance of the whole product is effectively improved.

This scheme carries out double-deck shell design through the shell structure to earth's surface monitoring devices, has carried out the resistance to compression design again on double-deck structure design's basis simultaneously, has not only promoted the secondary waterproof performance of product, still further promotion the compressive property of product, compare in traditional earth's surface monitoring devices shell structure, this structure can effectual reduction because of moist, leak and the problem that the pressure-bearing problem leads to the unable use of product, have very big promotion effect to the life of extension earth's surface monitoring devices product.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
