DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the utility model more clear, definite, the following will make further detailed description to the contents of the utility model combining with the drawings and specific embodiments. It can be understood that the specific embodiments described here are only used to explain the utility model, not limit the utility model. In addition, it also needs to be explained that in order to facilitate description, only the part related to the utility model is shown in the drawings, not all contents.

[0023] The embodiment proposes a kind of ore pulp pipeline monitoring device based on gravity induction and leakage detection, as shown in Figure 2 It includes:

[0024] Water pipe cover 1, it is made of several identical radian sub-pipe cover splicing combination, for being set in the outside of target flange plate, wherein, the edge diameter of water pipe cover 1 is narrowed.Before installing water pipe cover 1, flange plate needs to be cleaned, specifically, using cleaning cloth to clean ore pulp pipeline flange plate surface, remove impurities and moisture, ensure that flange plate surface is clean and free from oil stains, then water pipe cover 1 is divided into three equal parts (i.e. sub-pipe cover) and is aligned according to installation instruction, uses splicing notch and glass cement to realize seamless connection, ensure that each connection is tightly seamless, prevent water or ore pulp solution from seeping in.

[0025] Gravity sensor (not shown in the figure), clamped between target flange plate and water pipe cover 1.

[0026] Liquid leakage sensor, clamped between target flange plate and water pipe cover 1, and located at the bottom of target flange plate.

[0027] Mounting port 2, it is arranged on water pipe cover 1.

[0028] Operation unit (not shown in the figure), it is installed in mounting port 2, its signal input end is coupled with the signal output end of gravity sensor and liquid leakage sensor, and outputs gravity posture value and liquid leakage detection value.

[0029] Bluetooth transmission unit (not shown in the figure), it is installed in mounting port 2, for transmitting gravity posture value and liquid leakage detection value to host computer.

[0030] In the embodiment, by setting a water pipe cover 1 wrapped in the outside of flange plate, form a sealed waterproof space, gravity sensor and liquid leakage sensor are arranged in the sealed waterproof space, and by setting mounting port 2 on one side of water pipe cover 1, operation unit and bluetooth transmission unit are arranged in mounting port 2, the signal output by sensor is transmitted to host computer, so that the deformation tearing and leakage of flange plate are monitored in time.

[0031] It also includes a Bluetooth gateway (not shown in the figure) deployed near the waterproof sleeve 1. The gravity attitude value and leakage detection value output by the Bluetooth transmission unit are transmitted to the Bluetooth gateway. The Bluetooth gateway then forwards the gravity attitude value and leakage detection value to the IoT platform, and finally transmits them to the host computer through the IoT platform.

[0032] The above gravity sensors read microgravity components in the X, Y, and Z coordinates. After the waterproof sleeve 1 is fully installed, the number of the waterproof sleeve 1 is automatically registered to the host computer through the computing unit and Bluetooth transmission unit, and the initial gravity attitude value after installation is recorded. Every 5 seconds, the device will send the collected microgravity XYZ components through the Bluetooth IBEAON protocol and receive them through the Bluetooth gateway. The host computer compares the initial gravity attitude value to calculate the change in XYZ and judges the stress change of the flange. If it exceeds the set value, it is judged that the risk of cracking has occurred.

[0033] The aforementioned leakage sensor can take many forms. In one embodiment, the leakage sensor consists of at least two electrodes, which are respectively connected to two detection pins of the computing unit. Only one of the detection pins outputs a detection signal. When the two electrodes come into contact with the leakage, a current loop is generated to determine whether leakage has occurred. A pull-down resistor is connected to one of the electrodes to control the sensitivity of the electrode.

[0034] In another implementation plan, please refer to... Figure 2 The leak sensors are capacitive leak sensors 4, comprising at least three sensors arranged at different heights inside the waterproof sleeve 1. Their principle is to detect leaks by utilizing the change in capacitance between two electrodes. Under normal conditions, the capacitance between the electrodes is stable. When liquid leaks and comes into contact with the electrodes, it changes the dielectric constant between them, causing a change in capacitance. By detecting this change in capacitance, a leak can be determined. When seepage occurs, the capacitive leak sensor 4 located at the bottom of the waterproof sleeve 1 detects the leak first. As seepage increases, the liquid level in the waterproof sleeve 1 rises, subsequently being detected by the capacitive leak sensors 4 positioned higher. Based on the signals returned by the three capacitive leak sensors 4, the user can determine the degree of seepage in the flange.

[0035] Continue reading Figure 2 It also includes a monitoring unit 3 installed inside the mounting port 2. The monitoring unit 3 houses a computing unit, a Bluetooth transmission unit, and a battery. The battery provides local power to the computing unit and Bluetooth transmission unit and enables communication with the Bluetooth gateway. In the above feasible solution, if the computing unit, Bluetooth transmission unit, or battery malfunctions, the user can remove the entire monitoring unit 3 from the mounting port 2 for convenient maintenance of each unit.

[0036] likeFigure 3 As shown, the monitoring unit 3 comprises a barrel 301, and a cover 302 screwed on the open end of the barrel 301, and the tail of the barrel 301 is provided with a wire hole 303.

[0037] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable the ordinary skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the essence of the present application shall be covered within the protection scope of the present application.
