Technical Field

The invention relates to the technical field of landmark devices, in particular to a spherical landmark device.

Background

The induction coil used by the current landmark has the longest induction distance in the normal direction, after the landmark is buried in the ground, the inductor on the ground needs to reach the maximum induction distance, and the induction position error is the smallest, so that the induction coil in the landmark needs to be arranged in a correct way to enable the normal line to be in a vertical state when the landmark is buried.

In order to keep the normal line of the coil in a vertical state, the prior art adopts a method that liquid is injected into the shell, so that the induction coil floats on the liquid, and the aim of always keeping the normal line of the coil vertical is fulfilled. However, when the liquid injection device is used in a cold region with a low temperature, the injected liquid has good cold resistance so as to ensure that the liquid in the marker is not frozen in the cold region (50 ℃ below zero), otherwise, the induction coil cannot keep a vertical state, and the error becomes large. However, the price of the cold-resistant liquid is high, so that the manufacturing cost of the final whole product is high, and the market popularization is not facilitated.

Improvements are therefore needed.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a spherical landmark device with simple structure, low manufacturing cost and small induction error so as to solve the problems.

In order to achieve the purpose, the invention adopts the technical scheme that:

the utility model provides a spherical landmark ware, is including being used for the coil pack for ground receiver send signal, includes interior casing and shell body, interior casing is the globular thing that has the automatic reset function of just rectifying for weight under the weight, the fixed level of coil pack is placed in the interior casing, the shell body parcel is lived interior casing provides a sufficient accommodation space for interior casing ensures that interior casing is unrestricted to keep upright in the inside of shell body.

In a further technical scheme, the inner shell is spherical or ellipsoidal.

In a further technical scheme, the inner shell comprises an upper inner shell and a lower inner shell which are detachably connected, and solid or liquid fillers are arranged at the bottom of the lower inner shell so as to keep the whole inner shell in a tumbler state with a light upper part and a heavy lower part.

In a further technical scheme, the coil component further comprises an isolation baffle plate, wherein the isolation baffle plate is arranged above the solid or liquid filler, and the upper part of the isolation baffle plate is provided with a positioning hole for fixing the coil component and a reinforcing rib for reinforcing a mechanical structure.

In a further technical scheme, the outer shell comprises an upper shell and a lower shell which are detachably connected.

In a further technical scheme, the upper inner shell and the lower inner shell and the upper outer shell and the lower outer shell are detachably connected through threads.
