Problems solved by technology

Due to the small gap, the dust stuck in the gap is difficult to clean, and when the probe is stored, the dust stuck in the gap will fall into the storage box and enter the host of the inclinometer; in addition, it is necessary to clean the electronic components in the probe. When the device is overhauled or replaced, during the process of disassembling the tubular casing, the dust stuck in the gap is also easy to fall into the tubular casing and mix into the electronic components and cannot be removed, and the electronic components are easily damaged after being stained with dust

Embodiment 1

[0033] A protective inclinometer, such as figure 1 , figure 2 As shown, the probe includes a probe. The probe includes a plurality of tubular casings 1, and adjacent tubular casings 1 are detachably connected. Specifically, in this embodiment, adjacent tubular casings 1 are connected threadedly. The tubular housing 1 is provided with a protection unit. In this embodiment, two adjacent tubular housings 1 are taken as an example to describe the structure of the protection unit and the connection method with the tubular housing 1 .

[0034] The protection unit includes a sleeve 21 , two sealing sheets 2 and two limiting members 3 . Both ends of the two sleeves 21 are integrally formed with the two sealing sheets 2 , and the two sealing sheets 2 are provided with the sleeves. 21 are aligned with the mounting holes, the sealing sheet 2 and the sleeve 21 in this embodiment are made of soft elastic rubber. The limiting member 3 in this embodiment is in the shape of a metal mesh, a...

Embodiment 2

[0041] On the basis of Example 1, as image 3 and Figure 4 As shown, the overlapping area of ​​two adjacent tubular shells 1 in this embodiment is a connecting portion, and a sealing unit is provided between the connecting portion located on the inside and the connecting portion located on the outside. The structure of the sealing unit will be described by taking the sealing unit between them as an example.

[0042] The sealing unit includes an elastic block 4 and a guide assembly. The elastic block 4 and the guide assembly are located on the connecting parts of the outer side and the inner side respectively. The guide assembly includes a guide groove 14 and a vent channel 13. Axially extending, and the vent channel 13 and the guide groove 14 are distributed in an L shape. The upper end of the vent channel 13 communicates with the protective cavity 11, and the lower end communicates with the right end of the guide groove 14. The corresponding central angle of the guide groov...

Abstract

The invention relates to the field of geological exploration, in particular to a protective inclinometer. Including the probe, the probe includes a plurality of tubular shells, adjacent tubular shells are detachably connected, a protective unit is provided between the adjacent tubular shells, the protective unit includes two sealing pieces, and the two sealing pieces are respectively located in the adjacent two tubular shells The two sealing sheets are respectively fixed with the inner walls of the two tubular shells, and the two sealing sheets are provided with installation holes and are fixedly connected with the electric wires; a protective cavity is formed between the two sealing sheets and the tubular shell, and the protective cavity is connected with an air intake pipe, and the air intake pipe is connected with a Aspirated parts. The protective inclinometer of the present invention can prevent the electronic components in the probe from being damaged by external dust falling into the probe.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a protective inclinometer. Background technique [0002] Inclinometer is an instrument used to measure the apex angle and azimuth angle of engineering structures such as boreholes, foundation pits, foundations, walls and dam slopes. When the probe of the inclinometer is manufactured, in order to install various electronic components into the probe, the wires connected between various electronic components also need to be installed in the probe, so the probe usually includes multiple tubular shells, adjacent to each other. The tubular shells are connected by thread or snap connection. However, this results in a gap between the adjacent tubular shells. When the inclinometer is used, it needs to drill a hole in the soil layer, and the hole needs to go deep into the unstable soil layer and the stable layer below, and then put the measurement The inclined pipe is inserted into ...
