Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of gate monitoring device, specifically, it relates to a protection structure for double-shaft inclinometer based on gate monitoring. BACKGROUND

[0002] The double-shaft inclinometer is a double-shaft inclinometer sensor, commonly used for measuring horizontal angle change, and its principle is to use Euler angle to represent the rotation of a coordinate system, so that 360-degree inclination measurement can be realized. In water conservancy and hydropower engineering, the monitoring of the gate is related to the normal operation of the water gate. The monitoring of the operating posture of the gate is mainly realized by using a wired double-shaft inclinometer. During installation, the double-shaft inclinometer is first fixed on the base through bolts, and then the base is welded at the measurement point position of the gate. During the lifting process of the gate, the double-shaft inclinometer synchronizes with the gate action, and the sensor cable is reeled in or unreeled through the cable reel device. However, since a wired structure is used, if the cable reel device fails during the lowering process of the gate, the existing installation structure of the double-shaft inclinometer can cause the sensor cable to be pulled off or the connection between the sensor cable and the double-shaft inclinometer to fall off. On the other hand, the gate operates in water, which is heavy in water vapor and easily erodes the connection of the sensor cable, affecting the work of the double-shaft inclinometer. SUMMARY

Its vertical end face is welded to the measuring point position of the gate, and its horizontal end face has mounting holes at the four corners. The dual-axis inclinometer is mounted on the mounting panel through the mounting holes. One end of the dual-axis inclinometer is the probe, and the opposite end is the cable that comes with the dual-axis inclinometer, i.e., the dual-axis inclinometer cable. During installation, the dual-axis inclinometer cable needs to be connected to an external cable. The connection method can be a conventional cable connection method, such as: hinge connection, welding connection, snap-fit ​​connection, etc.

[0029] In this embodiment, a protective box is provided on the side of the mounting panel, which matches the cable side of the dual-axis inclinometer. The shape of the protective box is not particularly limited; it can be a conventional regular shape such as a cuboid or a cylinder. The bottom of the protective box is fixed to the mounting panel as an integral structure, or it can be fixed by bolts.

[0030] The protective box is hollow inside and open at both ends. A fixed inner box and a movable inner box are respectively provided on opposite sides inside the protective box. The shapes of the fixed inner box and the movable inner box should match the shape of the protective box.

[0031] The fixed inner box is in an integral structure with the protective box body, and the outer end of the fixed inner box faces the mounting panel. A first through hole is formed in the middle of the fixed inner box for the cable of the two-axis tilt angle instrument to pass through. The movable inner box is connected with the protective box body by sliding. The specific implementation structure is as follows: a sliding groove is arranged on the inner wall of the protective box body along the axial direction, and a sliding bar matched with the sliding groove is arranged on the outer wall of the movable inner box along the axial direction. The sliding bar is in an integral structure with the movable inner box. When the movable inner box is placed inside the protective box body, the sliding bar is embedded in the sliding groove. In a further preferred embodiment, the sliding groove has two symmetrically arranged sliding grooves, and the sliding bar has two symmetrically arranged sliding bars. A second through hole is formed in the middle of the movable inner box for the external cable to pass through. During installation, the end of the cable of the two-axis tilt angle instrument passes through the first through hole and then extends out of the protective box body. The end of the external cable passes through the second through hole. After the ends of the two cables are connected, the movable inner box is inserted into the protective box body along the sliding groove. Then, the external cable and the cable of the two-axis tilt angle instrument are adjusted to the appropriate position. Generally, the connection of the two cables is preferably arranged in the middle of the protective box body.

[0032] After adjustment, the external cable and the movable box body need to be fixed relative to each other, and the cable of the two-axis tilt angle instrument and the fixed box body need to be fixed relative to each other. The implementation structure is as follows: a first clamp member for fixing the cable of the two-axis tilt angle instrument is arranged on the outer end of the fixed inner box. One side end face of the first clamp member is tightly connected with the outer end of the fixed inner box, and the other side end face faces the direction of the mounting panel. A second clamp member for fixing the external cable is arranged on the outer end of the movable inner box. One side end face of the second clamp member is tightly connected with the outer end of the movable inner box, and the other side end face faces the direction of the external cable. It should be noted that the first clamp member and the second clamp member have the same structure. They are named separately here for the convenience of distinguishing and describing. The structures of the two are as follows:

[0033] The first clamping member comprises a first inner clamping member, a first outer clamping member sleeved outside the first inner clamping member, and a first adjusting screw for adjusting the first outer clamping member, the first inner clamping member is annular and the middle part thereof is aligned with the first through hole, and a first rubber sealing ring is arranged on the inner side wall of the first inner clamping member, the arrangement of the first rubber sealing ring further improves the effect of preventing water vapor from eroding the device. In order to facilitate the connection of the first clamping member and the fixed inner box and not affect the adjusting action of the first outer clamping member, in the embodiment, one side end face of the first inner clamping member is protruded relative to the end face of the first outer clamping member, and the end face of the first inner clamping member is tightly connected with the outer side end part of the fixed inner box, and the connection mode can adopt welding fixation. The second clamping member comprises a second inner clamping member, a second outer clamping member sleeved outside the second inner clamping member, and a second adjusting screw for adjusting the second outer clamping member, the second inner clamping member is annular and the middle part thereof is aligned with the second through hole, and a second rubber sealing ring is arranged on the inner side wall of the second inner clamping member, the arrangement of the second rubber sealing ring further improves the effect of preventing water vapor from eroding the device.
