[0029] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0030] Figure 1 FIG. 1 is a flow chart of a method for detecting wear of a delivery pipe provided by an exemplary embodiment of the present application. The detection method can be applied to a delivery pipe, such as Figure 1 As shown, the following steps are included:

[0031] Step 110: Acquire at least one initial detection point of the conveying pipe.

[0032] At least one initial detection point of the conveying pipe can be obtained based on the maintenance personnel's experience. The initial detection point of the conveying pipe can also be obtained through computer simulation. Computer simulation can simulate the conveying pipe and the simulated situation of the conveying pipe wear. If the thickness of the position with faster wear is increased in the design of the conveying pipe, then the position with faster wear should be determined as the initial detection point. The curved inner wall of the conveying pipe is usually more severely worn than the straight inner wall. In view of this situation, the thickness of the curved inner wall may be increased when the conveying pipe is manufactured to prevent the curved inner wall from being worn through or severely worn when the straight inner wall is less worn, which ultimately causes inconvenience in use or shortened service life. Alternatively, the degree of wear of the conveying pipe can be determined according to the wear speed, that is, the position point where the wear speed of the conveying pipe is greater than the preset wear speed threshold is the initial detection point.

[0033] Step 120: Compare the detection result of at least one initial detection point with the actual wear result to obtain a comparison result.

[0034] By comparing the detection result of the initial detection point with the actual wear result, the comparison result is obtained, thereby improving the accuracy of the comparison result. That is to say, the detection result of the initial detection point is compared with the actual wear result with the actual wear result as a reference or when the actual wear result is known, and then the comparison result is applied to the next step of operation, so that the comparison result obtained is more accurate. The actual wear result can be obtained by detection by a detector, and the detector can be an ultrasonic detector. In addition, only one initial detection point can be obtained and compared with the actual wear result corresponding to the initial detection point. All detection points in the area can also be determined at the same time, and then each point is compared with the actual wear result corresponding to each point. The detection result can be detected by pre-embedding a resistance wire at the initial detection point or setting a wear detection component to detect the detection result corresponding to the initial detection point. Or the detection result corresponding to the initial detection point can be directly obtained through simulation.

[0035] Step 130: Adjust the position of at least one initial detection point according to the comparison result to obtain at least one wear detection point corresponding to the at least one initial detection point.

[0036] The position of the initial detection point is corrected by comparing the detection result with the actual wear result to obtain the wear detection point. In other words, the detection point position is continuously iterated to correct or adjust the position of the initial detection point to obtain the wear detection point, i.e., the optimal detection point (i.e., the difference between the corresponding detection result and the actual wear result is small) to improve the accuracy of the conveying pipe wear detection, wherein iteration means continuously changing the position of the initial detection point to obtain the final wear detection point, i.e., the optimal detection point.

[0037] Step 140: Detect wear data of at least one wear detection point in real time.

[0038] Once the wear detection point is determined, the wear detection point can be directly applied, that is, the corresponding wear data at one or more wear detection points can be detected in real time, so that the wear condition of the inner wall of the conveying pipe can be understood in real time, thereby accurately predicting the wear condition of the conveying pipe.

[0039] Step 150: Calculate the wear degree of the conveying pipe according to the wear data of at least one wear detection point.

[0040] During the construction process, the wear degree of the conveying pipe is calculated based on the wear data at the wear detection point. In addition, wear failure can be predicted by setting thresholds.

[0041] The present application provides a method for detecting wear of a conveying pipe, including: obtaining at least one initial detection point of the conveying pipe, comparing the detection result of at least one initial detection point with the actual wear result to obtain a comparison result, adjusting the position of at least one initial detection point according to the comparison result, obtaining at least one wear detection point corresponding to the at least one initial detection point, detecting the wear data of at least one wear detection point in real time, and calculating the wear degree of the conveying pipe according to the wear data of at least one wear detection point. By comparing the detection result of at least one initial detection point with the actual wear result, adjusting the position of the initial detection point, obtaining at least one wear detection point that can accurately reflect the wear condition of the conveying pipe, thereby improving the wear detection efficiency and accuracy.

[0042] Figure 2 FIG. 1 is a flow chart of obtaining the initial detection point provided by an exemplary embodiment of the present application. Figure 2 As shown, based on the above embodiment, in one embodiment, step 110 may be specifically implemented as: simulating and acquiring at least one initial detection point of the conveying pipe.

[0043] The actual wear condition inside the conveying pipe can be obtained by simulating the conveying pipe and the material flowing in the conveying pipe. The conveying pipe simulated by simulation can accurately observe the position where the conveying pipe is severely worn. Usually, the experience value of the inspector's inspection of the conveying pipe is input into the simulation model. The experience value includes the position where the conveying pipe is severely worn and its corresponding wear data, and the predicted wear position of the conveying pipe. When the inspector inspects the conveying pipe, because there are many wear positions, especially the wear is more serious in the bent part of the conveying pipe. When inspecting the bent part, many positions are difficult to detect or it is impossible to detect the corresponding points of the bent part of the conveying pipe. Therefore, sometimes the inspector will estimate the bent part of the conveying pipe or the part that is difficult to detect, that is, estimate the position of severe wear.

[0044] In one embodiment, if Figure 2 As shown, step 110 may include:

[0045] Step 111: Simulate the conveying pipe through a static mechanical model.

[0046] Input parameters in the static mechanics model to simulate the delivery pipe, where the input parameters include the model, length, and material of the delivery pipe. The static mechanics model can simulate a similar delivery pipe based on the shape of the actual delivery pipe, making it easier to obtain the wear area of ​​the inner wall of the delivery pipe and the force magnitude of the inner wall of the delivery pipe.

[0047] Step 112: Simulating the material through a dynamic mechanical model, wherein the material flows in the conveying pipe to simulate the conveying process of the conveying pipe.

[0048] In actual conveying pipe wear, the material wears the inner wall of the conveying pipe while flowing. The dynamic mechanics model can be used to simulate the process or result of the material wear of the conveying pipe. The flow direction and / or speed of the material can be input into the dynamic mechanics model to simulate the conveying process of the material actually wearing the conveying pipe. By simulating the material by dynamic mechanics, it is relatively easy to simulate the process of the material flowing in the conveying pipe, thereby simulating the wear process of the conveying pipe and obtaining the pressure value of the material on the inner wall of the conveying pipe, wherein the wear object can be concrete slurry.

[0049] Step 113: Obtain the pressure value of the material on the wall of the conveying pipe.

[0050] When the material flows in the conveying pipe, the material contacts the pipe wall and forms pressure to squeeze the pipe wall. As the material flows through the conveying pipe, the material will continue to squeeze the pipe wall. When the material continuously exerts a certain pressure on the pipe wall, the pipe wall will continue to become thinner under the friction of the pressure. The pressure value can show the wear of the material on the pipe wall.

[0051] Step 114: selecting at least one position point corresponding to a pressure value that meets a preset condition among the pressure values ​​as at least one initial detection point.

[0052] At least one position point corresponding to the pressure value that meets the preset conditions in the pressure value is selected as the at least one initial detection point, wherein at least one position point corresponding to the pressure value greater than the preset pressure threshold can be selected as at least one initial detection point according to the wear condition of each position of the entire conveying pipe, and the position point is one or more. The pressure value is positively correlated with the wear condition of the inner wall of the conveying pipe. The position of the inner wall of the conveying pipe corresponding to the larger pressure value is usually the position with the most serious wear. The initial detection point can be selected using the pressure value. In addition, the pressure value can be multiple, and the multiple pressure values ​​can be sorted in ascending order in sequence, and at least one position point corresponding to the pressure value with a sorting value less than or equal to the preset sorting threshold is selected as at least one initial detection point. For example, there are A, B, C and D pressure values, and A, B, C and D are sorted in ascending order, wherein the pressure value corresponding to A is 10Pa (Pascal), the pressure value corresponding to B is 5Pa, the pressure value corresponding to C is 6Pa, and the pressure value corresponding to D is 20Pa. Then the sorting should be D>A>C>B. Select a pressure value with a sorting value less than 3, and the position points corresponding to D and A can be selected as the initial detection points.

[0053] Figure 3 FIG. 1 is a flow chart of a method for obtaining wear detection points provided by an exemplary embodiment of the present application. Figure 3 As shown, based on the above embodiment, step 130 may include the following steps:

[0054] Step 131: Calculate a first difference value between a detection result of at least one initial detection point and an actual wear result.

[0055] By calculating the first difference between the detection result of the initial detection point and the actual wear result, it is determined whether the arrangement of the initial detection point can accurately reflect the wear degree of the conveying pipe. The first difference actually also reflects the accuracy between the detection result and the actual wear result.

[0056] Step 132: When the first difference value is greater than or equal to a preset difference threshold, adjust the position of at least one initial detection point until at least one corresponding wear detection point is obtained.

[0057] When the first difference value is greater than or equal to the preset difference threshold, it means that the difference between the detection result and the actual wear result is large, that is, the similarity between the two is low. At this time, the position of the initial detection point can be adjusted iteratively to obtain the final wear detection point, so that the method of obtaining the wear detection point is simpler and faster, and the obtained wear detection point is also more accurate.

[0058] Figure 4 FIG. 1 is a flow chart of a method for obtaining wear detection points provided by another exemplary embodiment of the present application. Figure 4As shown, based on the above embodiment, step 132 may include the following steps:

[0059] Step 1321: When the first difference value is greater than or equal to a preset difference threshold, adjusting parameters in the dynamic mechanical model, the parameters including the flow direction and / or flow speed and / or mass of the material.

[0060] When the first difference value is greater than or equal to the preset difference threshold, that is, the detection result is not close to the actual result and the deviation is large, then the flow direction and / or flow velocity and / or mass and other parameters of the material in the dynamic mechanical model are adjusted in the computer simulation. The flow direction and / or flow velocity and / or mass of the material will affect the position where the material wears the inner wall of the conveying pipe, so when the first difference value is greater than or equal to the preset difference threshold, the parameters in the computer simulation are readjusted to redetermine the wear position of the conveying pipe.

[0061] Step 1322: Detect the pressure value of the inner wall of the delivery pipe.

[0062] When the material wears the inner wall of the conveying pipe, it will also wear the conveying pipe. Due to the different weights and types of the materials, the pressure values ​​causing the wear on the conveying pipe are different.

[0063] Step 1323: Determine the update detection point according to the pressure value.

[0064] Because the pressure values ​​of the material wear conveying pipe are different, the wear degree of the conveying pipe is different. In other words, the greater the pressure value of the material on the inner wall of the conveying pipe, the greater the wear degree of the corresponding conveying pipe. When the detection result of the above wear detection point is significantly different from the actual wear result, it means that the wear detection point needs to be updated, or it can also mean that the wear position corresponding to the above wear detection point and the actual wear result does not correspond. Therefore, it is necessary to reselect the wear detection point, that is, update the detection point.

[0065] Step 1324: Obtain the detection result of the update detection point.

[0066] The detection result corresponding to the updated detection point can be detected by pre-buried resistance wire or other components, and the detection result can be uploaded to the database or cloud, etc., and the detection result of the updated detection point can be obtained through the database or cloud. Or the detection result of the updated detection point is detected in real time and its detection result is directly applied.

[0067] Step 1325: Calculate a second difference value between the detection result of the updated detection point and the actual wear result.

[0068] The second difference value is used to determine again whether the detection result is close to the actual wear result. If not, the detection point needs to be updated again.

[0069] Step 1326: When the second difference value is less than the preset difference threshold, determine that the update detection point is a wear detection point.

[0070] When the second difference value is less than the preset difference threshold, that is, the detection result is close to the actual wear result, then it can be determined that the updated detection point is a wear detection point, and the wear of the inner wall of the conveying pipe corresponding to the wear detection point is more serious.

[0071] When the second difference value is greater than or equal to the difference threshold, it means that the detection result is not close to the actual wear result, or the difference between the detection result and the actual wear result is large, then the detection point is not accurately determined, and the position of the detection point needs to be updated again until the wear detection point is determined.

[0072] Figure 5 FIG. 1 is a flow chart of a method for detecting wear of a delivery pipe provided by another exemplary embodiment of the present application. Figure 5 As shown, based on the above embodiment, a wear detection component is provided inside the conveying pipe at a position corresponding to the initial detection point, wherein step 140 may include the following steps:

[0073] Step 141: Detect wear data of at least one wear detection point by a wear detection component.

[0074] A wear detection component is provided inside the position of the wear detection point corresponding to the conveying pipe, and the wear data of the wear detection point is detected by the wear detection component. Therefore, in actual construction, the wear of the conveying pipe can be detected in real time by the wear detection component, and the obtained conveying pipe wear data is more accurate, convenient and quick.

[0075] Figure 6 FIG. 1 is a flow chart of obtaining wear results provided by an exemplary embodiment of the present application. Figure 6 As shown, based on the above embodiment, the wear detection component includes a resistance wire, and step 141 may include the following steps:

[0076] Step 1411: Detect the impedance value of the resistance wire.

[0077] The wear detection component includes a resistance wire. When the corresponding position of the detection resistance wire is worn, the resistance wire is also worn, thereby changing the impedance value of the resistance wire. The impedance value of the resistance wire corresponds to its length, and the impedance value of the resistance wire can be accurately detected. Therefore, the accuracy of wear detection can be improved by detecting the impedance value of the resistance wire.

[0078] Step 1412: Obtain wear data based on the impedance value, wherein the impedance value is proportional to the wear data.

[0079] According to the impedance value, wear data is obtained. The impedance value is proportional to the wear data. The wear data can be used as the test result, that is, V=k*R, where V is the wear data, R is the measured impedance, and k is the conversion coefficient. According to the formula, before obtaining the wear detection point, the impedance value is substituted into the formula, and then the k value is continuously adjusted to make the test result close to the actual wear result, wherein the k value can be multiple, corresponding to the impedance values ​​of multiple detection position points. For example, taking k1, k2, k3 and k4 as examples, by adjusting the size of k1 and / or k2 and / or k3 and / or k4, the test result is adjusted. Therefore, the accuracy of the wear data is improved, and the direct detection of the wear degree of the conveying pipe can also be achieved.

[0080] The wear detection component may include a plurality of resistance wires, and impedance values ​​of the plurality of resistance wires are detected to obtain a plurality of impedance values, and wear data is obtained according to the plurality of impedance values.

[0081] First, the impedance values ​​of multiple resistance wires are detected. The resistance wires can be set in parallel to ensure that the resistance wires do not interfere with each other, that is, the corresponding impedance values ​​can be calculated based on the multiple resistance wires set in parallel. In addition, after obtaining multiple impedance values, the multiple impedance values ​​can be weighted (weighted average) to obtain a final impedance value, and the wear data of the conveying pipe can be determined by the final impedance value; after obtaining multiple impedance values, the maximum impedance value can be selected, and then the wear data can be obtained based on the impedance value to make the wear data more accurate. In addition, the resistance wire can be set vertically to the pipeline wall.
