Description

Fixed inclinometer

Technical Field

The utility model relates to a measuring instrument technical field is a fixed inclinometer particularly.

Background

In the process of engineering construction, the displacement monitoring is needed to be carried out on the geotechnical body or the engineering structure at a certain depth below the ground so as to know whether the geotechnical body or the engineering structure changes or not in the construction process, and collapse, deformation of the underground structure and other conditions are avoided.

In a conventional fixed inclinometer, when the stratum is displaced, the inclinometer tube is displaced, thereby causing the sensor installed in the tube to be inclined. The detection mode is directly detected by the sensor, on one hand, the measurement precision is only related to the sensor, and the measurement precision is reduced along with the low precision of the sensor, and meanwhile, the detection of deeper soil displacement and underground structures is difficult.

Based on the above problems, chinese patent CN201610502808.9 discloses a fixed inclinometer and a method for using the same, wherein a plurality of single inclinometers are connected by hinges to continuously measure the inclination of any position of the foundation pit wall, but it needs to ensure that the hinge guide wheel is tightly attached to the inclinometer pipe, so it needs to install a rail in advance in the inclinometer pipe before measurement to use, and it is more suitable for measuring structures such as the foundation pit with vertical structure; chinese patent CN201821479733.8 discloses a fixed inclinometer for automatic monitoring, which is characterized in that a guide wheel mechanism is installed on an inclinometer probe, and a plurality of inclinometers are connected through a steel wire rope, so as to achieve the purpose of measuring the horizontal displacement in a deeper position, but it can only measure the horizontal displacement change at the position where the inclinometer is installed, and the measurement result is easily influenced by the guide wheel mechanism.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve the not enough of prior art, provide a measure convenient, and the accurate fixed inclinometer of measuring result

In order to realize above-mentioned purpose, design a fixed inclinometer, including connecting rod, casing, wire and inclinometer sensor, still include at least one locating support, the locating support is equipped with the base, and the base passes through the screw connection with the casing, is equipped with four elastic connection spare on the base, and elastic connection spare evenly sets up in casing week side, and the elastic connection spare middle part is outwards heaved, and the elastic connection spare department of heaping is equipped with the notch for connect the gyro wheel.

The utility model discloses still have following preferred technical scheme:

furthermore, connecting supports are arranged at two ends or one end of the fixed inclinometer and connected with universal connecting rods, and the universal connecting rods are used for connecting universal connecting rods of another fixed inclinometer.

Beneficial effects of the utility model

The utility model provides an advantage of fixed inclinometer includes but is not limited to: both can the deviational survey alone, also can connect the back with a plurality of fixed inclinometers, carry out the deviational survey to improve overall measuring precision, can adapt to anomalous engineering structure that awaits measuring simultaneously, reduced other parts on the inclinometer to the influence of deviational survey result, whole deviational survey's operation is more simple and convenient.

Detailed Description

The technical solutions adopted by the present invention are further explained below by means of drawings and examples, so that those skilled in the art can better understand the technical solutions adopted by the present invention.

Fig. 1 is the utility model provides a fixed inclinometer's overall structure schematic diagram, it is shown with reference to fig. 1, middle for the protection the sensor housing 6 of sensor, locating

support

5, 7 about the outside of one section distance inwards at sensor housing 6's both ends is installed respectively, and linking bridge 4 and lower linking bridge 8 are equipped with respectively at sensor housing 6's both ends, it all is used for connecting the connecting rod to go up linking bridge and lower linking bridge, the connecting rod includes an universal connecting rod, can be connected with another fixed inclinometer through the connecting rod.

Referring to fig. 2, for the utility model provides an universal connecting rod, universal connecting rod makes including the pin thread and the box of interconnect the upper segment and the lower extreme of connecting rod can wind the junction of pin thread and box rotates.

Refer to fig. 3, for the utility model provides a sensor housing and locating support complex schematic structure, the locating support passes through the base to be fixed the sensor housing outside is equipped with four elastic connection spare on, and elastic connection spare evenly sets up in casing week side.

Referring to fig. 4, for the utility model provides a partial structure schematic diagram of locating support base, the elastic connection spare middle part that is equipped with on the base outwards heaves, and elastic connection spare department of heaping is equipped with the notch for connect the gyro wheel, be used for making fixed inclinometer can slide from top to bottom.

The fixed inclinometer assembled by adopting the mode can be independently assembled or a plurality of inclinometers are assembled together to perform measurement.

The utility model provides a concrete working method of fixed inclinometer as follows, according to the degree of depth of waiting to log a well, with a plurality of fixed inclinometers through under the preceding inclinometer the mode that connecting rod is connected on connecting rod and the next inclinometer, put into downwards along the inner wall of waiting to log a well, the gyro wheel can be in the same direction as the inner wall of waiting to log a well and slide downwards, when the bending of certain angle appears in the well that awaits measuring, universal connecting rod on the connecting rod can buckle according to the angle of buckling automatically for each inclinometer both ends can both be supported on the inner wall of the well that awaits measuring.
