Description
Technical Field
The invention relates to the field of inclinometers, in particular to a fixed inclinometer with a connecting rod and a measuring point box which are separately arranged.
Background
The fixed inclinometer is mainly used for long-term automatic monitoring of deep displacement in the infrastructure or natural soil body such as a side slope, a dam, a deep foundation pit and the like. The working principle is to measure the change of the included angle between the axis of the inclinometer pipe and the plumb line, thereby calculating the horizontal displacement of the measured structure in different depths and different directions. In the long-term monitoring process, if the fixed inclinometer deviates to a new position from an initial position, the internal displacement can be automatically calculated through an initial measurement angle and a current real-time measurement angle, so that early warning is carried out in advance, and accidents are prevented.
Referring to fig. 1, a schematic diagram of a fixed inclinometer 100 ' in the prior art is shown, where the fixed inclinometer 100 ' includes an inclinometer tube 1 ', a hanging ring 2 ' disposed at the outer end of the top of the inclinometer tube 1 ', a connecting screw rod 3 ' disposed inside the inclinometer tube 1 ' and connected to the hanging ring 2 ', a plurality of inclinometer probes 4 ', and an extension bar 5 ' connected to the bottom of the inclinometer tube 1 '. Each inclinometer probe 4 'includes a connecting rod 40', a station box 43 'integrated with the connecting rod 40', and a guide wheel 42 'mounted on the connecting rod 40'. Because the measuring point box 43 ' and the connecting rod 40 ' are integrally arranged, when a circuit board and a lead in the measuring point box 43 ' are damaged or water and air flow in to cause short circuit and failure, a supplier needs to return to replace the whole inclinometer probe 4 ' and even the whole fixed inclinometer 100 ', thereby increasing the cost and wasting the cost; in addition, the overall length of the fixed inclinometer 100 'is fixed, so that if a structure to be measured which is not completely matched with the fixed inclinometer 100' appears on site, the fixed inclinometer 100 'is out of service and the fixed inclinometer 100' needs to be newly equipped, which causes inconvenience in use.
Chinese utility model CN210862644U patent discloses a fixed inclinometer, and this fixed inclinometer includes a plurality of inclinometer probe, and each inclinometer probe is connected end to end in order to overcome the technical problem that it is difficult to put into the inclinometer through wire rope connection to be difficult to bear axial pressure and lead to terminal inclinometer probe through the mode end to end that the ball pivot is connected. Each inclinometer probe disclosed in the patent comprises a connecting rod, a connecting body and a cable, wherein the connecting body and the cable are integrally arranged with the connecting rod, a sensor for monitoring is arranged in the connecting body, and the sensor is electrically connected with the cable to transmit signals and current. However, the fixed inclinometer still has the following defects in the field use process: 1) because the connecting body and the connecting rod are integrally arranged, when a sensor in the connecting body is damaged or a connecting circuit is affected with damp and fails, the whole inclinometer probe needs to be replaced, so that cost and pressure are caused; 2) when the fixed inclinometer is used in a field, if a measured structure which is not matched with the whole length of the fixed inclinometer appears, the fixed inclinometer loses effectiveness, and a supplier needs to return to reassemble the fixed inclinometer which is matched with the depth of the measured structure in the field; 3) when the fixed inclinometer is replaced in different monitoring environments, the fixed inclinometer needs to be returned to a supplier for reassembly (the reason of waterproof failure in the same 2), so that the fixed inclinometer is not beneficial to multiple uses of customers and also causes the increase of cost; 4) the cable and the sensor in the connecting body are not convenient for users to disassemble on the construction site in a mode of welding on the circuit board.
Therefore, there is a need to design a new fixed inclinometer to overcome the above mentioned drawbacks.
