Description

TECHNICAL FIELD

[0001] The utility model relates to displacement monitoring technical field, concretely is a water conservancy project slope displacement internet of things intelligent monitoring device. BACKGROUND

[0002] The water conservancy project slope is the common structure form in water conservancy project, is mainly divided into natural slope and artificial slope, has the function such as keeping water and soil, preventing landslide. The water conservancy project slope design needs to follow the principle of safe and applicable, economic and reasonable, and carries out according to relevant norms such as " water and hydroelectric power engineering slope design specification ". The slope level is divided according to the relationship with the safety of engineering and main building and the loss size after the accident, and different levels correspond to different safety coefficient standards and reinforcement processing requirements. When designing, the height, slope, lithology etc. of slope need to be considered, and the reasonable slope structure and protection measures are determined in combination with the actual situation of engineering.

[0003] The slope needs to be monitored in real time after the completion of engineering, including displacement monitoring (internal and surface displacement), crack monitoring etc. The monitoring section should select the parts with poor geological conditions, large deformation or high slope. The horizontal interval of first-class slope displacement monitoring point should not be greater than 35m, the second-class slope should not be greater than 50m, and the third-class slope should not be greater than 65m. Through scientific design, stability analysis, reinforcement measures and monitoring, the safety and stability of water conservancy project slope can be effectively guaranteed.

[0004] In construction, the slope surface displacement often uses " tension line type displacement monitoring sensor " to complete monitoring, although it is called tension line type displacement monitoring sensor, but actually the angle displacement sensor is used, only the tension line method is used. By binding the steel wire in the fixed point, the steel wire is wound around the fixed pulley of the measuring point and connected with the weight, when the relative displacement of two points occurs, the steel wire will be tensioned or relaxed, thereby driving the fixed pulley to rotate and being monitored by the corresponding angle displacement monitoring sensor, through the internet of things intelligent monitoring technology, remote online monitoring can be realized, and the use is very convenient.

[0005] However, for large amplitude slope displacement, the steel wire is easy to drive the fixed pulley to rotate and be monitored by the angle displacement sensor, but because the steel wire and the fixed pulley surface are smooth, the friction between them is small, for the displacement distance between two points is small and the displacement is slow, the problem of inaccurate monitoring is easy to occur, therefore, our company designs and proposes a water conservancy project slope displacement internet of things intelligent monitoring device which is not limited to displacement distance, displacement speed and monitoring accuracy. CONTENT OF THE UTILITY MODEL

[0006] The utility model provides a water conservancy project side slope displacement internet of things intelligent monitoring device for solving the problem that the prior art water conservancy project side slope displacement internet of things intelligent monitoring device only adopts angle displacement sensor to monitor side slope displacement and is prone to inaccurate monitoring when displacement distance is small and displacement is slow.

[0007] To solve the above technical problems, the utility model provides the following technical scheme:

[0009] Preferably, the concrete foundation of the fixed point base and the measuring point base is in the shape of "convex", and a protective cover is installed on the corresponding concrete foundation outside the fixed point support, the tensioned wire displacement sensor, the measuring point support, the pulley seat, the fixed pulley, the angle displacement sensor, and the weight, the lengthened steel wire penetrates and extends to the inside of the protective cover, and a waterproof cover is further installed on the top of the protective cover.

[0010] Preferably, a protective sleeve is sleeved on the surface of the lengthened steel wire, both ends of the protective sleeve are inserted into the protective cover, and a sealant is arranged between the protective sleeve and the protective cover, and the protective sleeve is installed on the ground through a support frame.

[0011] Preferably, the support frame includes a reinforcing bar parallel to the protective sleeve above the protective sleeve, an inclined bracing rib fixed between the reinforcing bar and the protective sleeve, and an inclined bracing rod fixed on the front and back surfaces of the reinforcing bar and inclined to the front and rear sides, and the bottom of the four inclined bracing rods of the same support frame is provided with a concrete foundation.

[0012] Preferably, the lower ends of the fixed point support, the measuring point support, and the inclined bracing rod are flush with or extend downward from the corresponding concrete foundation, respectively.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] This invention, based on existing angular displacement sensor monitoring technology, applies a fixed anti-slip rubber coating to the groove of the fixed pulley and connects the coated steel wire to the end of the extended steel wire to cooperate with the fixed pulley. This increases the friction between the two, eliminating the problem of inaccurate monitoring caused by slippage. In addition, by installing a pull-wire displacement sensor connected to the extended steel wire on the fixed point bracket, the extension and retraction of the extended steel wire can be directly monitored by the pull-wire displacement sensor. This not only avoids the situation where the fixed pulley slips and stops rotating due to small displacement distance or slow displacement, resulting in inaccurate monitoring, but also improves the reliability of slope displacement monitoring and enhances slope safety through dual monitoring.
