Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy pipeline laying, and particularly relates to a pipeline laying device for water conservancy construction. Background Art

[0002] During the process of water conservancy construction, pipelines need to be arranged to guide the flow of water, and a frame is often used to support the laid pipelines.

[0003] Referring to the Chinese patent with the patent announcement number CN222334688U, a fixed support for pipeline laying in a water conservancy project is disclosed, including a fixed seat. A through groove is opened on the fixed seat, and a moving adjustment mechanism is arranged inside the through groove of the fixed seat. The top of the moving adjustment mechanism is fixedly connected with a fixing plate that is slidably connected to the fixed seat. A fixing mechanism for providing fixation to the pipeline is arranged on the fixing plate. The pipeline can be installed and fixed through the arranged fixing mechanism, improving the stability of the pipeline. At the same time, a moving adjustment mechanism is arranged at the bottom of the fixing mechanism to adjust the left and right positions during pipeline installation.

[0004] However, in conventional methods, after the pipeline is supported by the bottom bracket, the top bracket is often used to press down on the pipeline from top to bottom for limiting. When a large pressure is applied above the laying frame, it will completely squeeze towards the outer wall of the pipeline, easily causing pipeline damage. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Embodiment 1: Refer to Figures 1-5, A pipeline laying device for water conservancy construction, including multiple groups of laying frames. The laying frame is provided with a support frame 1, and a pipe body 2 is placed on the support frame 1. The support frame 1 is set in a V-shaped structure. Both sides of the top of the support frame 1 are rotatably connected with a limit frame 3 through pins. Both sides of the support frame 1 are vertically penetrated with a column 4. The bottom end of the column 4 is installed with a bottom plate 401, and the top end of the column 4 is installed with a fixed head 5. The fixed head 5 is located above the corresponding outer wall of the support frame 1. The outer wall of the column 4 is slidably connected with a movable head 6. A spring telescopic rod 7 is connected between the bottom of the movable head 6 and the bottom plate 401. During the laying process, the laying frames are distributed along the extension of the pipe body 2. First, the bottom ends of the columns 4 on both sides of the support frame 1 are fixedly installed with the bottom plate 401 on the bottom of the pit, so that the support frame 1 is placed naturally and there is a certain gap between the bottom end of the support frame 1 in the natural placement state and the bottom of the pit. Then, the limit frames 3 on both sides of the support frame 1 are in an open state, as Figure 1 shown. Through the V-shaped structure setting of the support frame 1 and the open limit frames 3, it is convenient to align and place the pipe body 2; then the limit frames 3 are closed as Figure 2 shown, so that the support frame 1 and the two limit frames 3 form a rhombus structure to wrap the pipe body 2. After backfilling the soil, the limit frames 3 apply pressure on the upper part of the limit frames 3 to limit the upper part of the pipe body 2;

[0030] During use, under the action of the gravity of the pipe body 2, pressure is applied downward on the support frame 1, so that the support frame 1 moves downward until it touches the bottom of the pit, and the support frame 1 squeezes the telescopic part of the movable head 6 and the spring telescopic rod 7. The limit frame 3 moves downward a certain distance with the support frame 1, so that the inner surface of the limit frame 3 facing the pipe body 2 contacts the top of the fixed head 5; thus, during use, when the pipe body 2 is subjected to a large downward pressure, the whole pipe body 2 will apply downward pressure to make the support frame 1 apply downward pressure. When the support frame 1 drives the limit frame 3 to apply downward pressure, the fixed column 4 applies an upward reverse force to the movable limit frame 3. Through the upward reverse force of the limit frame 3 through the column 4, the pressure applied to the pipe body 2 above the corresponding position of the limit frame 3 is relaxed;

[0031] And after the support frame 1 and the two limit frames 3 are closed to form a rhombus structure, the inclined surfaces on the four sides are used to disperse the downward pressure, so as to avoid the downward pressure from acting completely on the top end of the pipe body 2;

[0032] By using the rotatable and movable setting method of the limit frame 3, when closing, the middle position of the limit frame 3 fits with the outer wall of the pipe body 2. When subjected to downward pressure from above, the position of the limit frame 3 closest to the ground above the position where it fits with the pipe body 2 is the fastest to receive the pressure, and the pressure received is also greater than the pressure received by the part of the limit frame 3 close to the support frame 1. That is, the position where the limit frame 3 fits with the pipe body 2 forms a fulcrum and forms a lever. When subjected to upward pressure, the limit frame 3 may generate an upward driving force on one side of the support frame 1, so that this force buffers the downward force directly acting on the support frame 1 by the pipe body 2;

[0033] Meanwhile, during the long-term use process, due to the movable setting of the limiting frame 3, during the thermal expansion and contraction process of the pipe body 2 during long-term action, the covering area of the laying frame on the pipe body 2 can adaptively change through the movable limiting frame 3, thereby avoiding damage or wear to the pipe body 2 caused by excessive extrusion due to thermal expansion and contraction of the pipe body 2;

[0034] In summary, through the movable settings of the support frame 1 and the two limiting frames 3, a diamond-shaped structure laying frame for covering the outer wall of the pipe body 2 is formed, and the fixed head 5 connected by the column 4 and the movable head 6 connected by the spring telescopic rod 7 are used to support the support frame 1 and the limiting frame 3, thereby effectively improving the stability effect of limiting the pipe body 2, as well as improving the bearing capacity and buffering capacity of the external pressure around the pipe body 2, and improving the applicability of the long-term laying and use of the pipe body 2.

[0035] In the present invention, the limiting frame 3 is provided with a limiting plate 301 rotatably connected to the support frame 1. A plurality of connecting strips 302 are installed at the end of the limiting plate 301 away from the support frame 1. The connecting strips 302 between the two limiting frames 3 are arranged at intervals and staggered, so as to improve the applicability and adjustment effect of the two limiting frames 3 in limiting pipes 2 of different sizes when they are closed through the staggered connecting strips 302.

[0036] In the present invention, a plurality of pressure grooves 303 are formed on the outer wall of the limiting frame 3 away from the pipe body 2. The pressure grooves 303 are arranged at the position of the outer wall of the limiting plate 301 away from the pipe body 2. One side of the pressure groove 303 close to the support frame 1 is perpendicular to the surface of the limiting frame 3, and the side of the pressure groove 303 away from the support frame 1 is inclined. Therefore, after the landfill soil is filled, the upper pressure will cause part of the soil to exert pressure on the vertical surface close to the support frame 1 in the pressure groove 303, and the upper pressure will be dispersed along the inclined extension direction of the limiting frame 3, thereby further improving the bearing capacity and the buffering effect of the pressure.

[0037] In the present invention, an embedding groove is formed on the inner side surface of the limiting frame 3 facing the pipe body 2. A magnetic attraction sheet 8 is installed in the embedding groove. The fixed head 5 is horizontally arranged. An installation groove is formed at the position corresponding to the magnetic attraction sheet 8 at the top of the fixed head 5, and a magnetic block is fixed in the installation groove. Therefore, after the two limiting frames 3 on both sides are closed, the magnetic attraction operation of the magnetic block and the magnetic attraction sheet 8 is used to assist in stabilizing the limiting frame 3, improving the limiting stability effect of the limiting frame 3 and the support frame 1 on the pipe body 2, and also preventing the limiting frame 3 from tilting during soil filling, which affects the actual use effect of the laying frame; and the magnetic attraction is used to assist in fixing without affecting the movable setting effect of the limiting frame 3.

[0038] In the present invention, extrusion blocks 9 are installed on the inner sides of the support frame 1 and the limit frame 3. The extrusion blocks 9 are made of silicone material. The extrusion blocks 9 are distributed on both sides of the contact position of the pipe body 2. The outer wall of the extrusion block 9 is in an arched arc structure. A horizontally penetrating notch 901 is formed in the outer wall of the extrusion block 9. The arc angle of the cross-section of the notch 901 is greater than 180 degrees. When the two limit frames 3 are closed, auxiliary limiting is carried out by contacting both sides of the contact position of the pipe body 2 through a plurality of extrusion blocks 9. When the pipe body 2 is subjected to an external applied force and moves, buffering is carried out by squeezing the extrusion blocks 9 and deforming the notch 901. By setting the arc angle of the cross-section of the notch 901, the position of the notch 901 deforms inward to increase the buffering resistance and the reset effect.

[0039] Embodiment 2: Refer to Figures 1-5 , a pipeline laying device for water conservancy construction. On the basis of Embodiment 1, a pressure monitoring module one is arranged at the fixed head 5 for real-time monitoring of the extrusion force between the fixed head 5 and the limit frame 3. A pressure monitoring module two is arranged at the movable head 6 for real-time monitoring of the extrusion force between the movable head 6 and the support frame 1. The monitoring data of the pressure monitoring module one and the pressure monitoring module two are uploaded to the cloud. The data uploaded by the pressure monitoring module one generates a pressure coefficient one PC1, and the data uploaded by the pressure monitoring module two generates a pressure coefficient two PC2. The data is comprehensively analyzed and processed in the cloud for evaluation, and an evaluation coefficient EC is generated. The calculation formula is: EC = a×PC1 + b×PC2, where a and b are weight coefficients determined according to the actual situation, and a reminder is given in time when problems are found in the evaluation. When the evaluation coefficient is greater than the preset reference coefficient, it indicates that there is a problem with the position of the laying frame, and an alarm is given in time to remind the staff. When the evaluation coefficient is less than the preset reference coefficient, it indicates that the laying frame is in normal use; thus, the safety monitoring effect of the laying frame during long-term use is improved, and the accuracy and effectiveness of the analysis and evaluation of the normal use of the laying frame are improved through the comprehensive analysis of the monitoring data at the positions of the fixed head 5 and the movable head 6.

[0040] In the present invention, a distance monitoring module one is arranged on the movable head 6 for real-time monitoring of the distance between the movable head 6 and the fixed head 5. The distance monitoring module one is uploaded to the cloud for comprehensive analysis of the monitoring data of the pressure monitoring module one. A pressure coefficient one is generated through the comprehensive analysis of the data monitored by the distance monitoring module one and the data monitored by the pressure monitoring module one. Thus, the pressure coefficient one at the position of the fixed head 5 is comprehensively analyzed through the distance difference between the movable head 6 and the fixed head 5, and problems can be comprehensively analyzed for different states of the subsidence of the column 4 or the loose soil at the top of the limit frame 3;

[0041] An algorithm based on Gaussian process regression is used to calculate the pressure coefficient one, and the calculation logic is:

[0042] Step 1: Data collection. Continuously collect the extrusion force data P1 of the pressure monitoring module 1 and the distance data D1 of the distance monitoring module 1.

[0043] Step 2: Dataset construction. Use P1 and D1 as input features to construct the feature matrix X1. At the same time, prepare the target values y1 of the corresponding pressure coefficient 1, which can be obtained through historical experimental data, expert experience, or actual measurement. Divide the dataset into a training set and a test set, and the ratio can be set to 8:2. The training set is used to train the model, and the test set is used to evaluate the performance of the model.

[0044] Step 3: Gaussian process regression model construction and training. Select a suitable kernel function. Commonly used kernel functions include the radial basis function RBF, and its form is where is the signal variance, l is the length scale, and the kernel function is used to describe the similarity between data points. Initialize the Gaussian process regression model, and input the feature matrix X1 and the target values y1 of the training set into the model for training. During the training process, the model will determine the parameters of the kernel function, such as and l, by maximizing the marginal likelihood estimation.

[0045] Step 4: Calculate the pressure coefficient 1. For the real-time collected P1 and D1 data, after preprocessing, form the input vector x new , and input it into the trained Gaussian process regression model. The model will output the predicted pressure coefficient 1 PC1 and the corresponding prediction variance The prediction variance can reflect the uncertainty of the prediction.

[0046] In the present invention, a distance monitoring module 2 is provided on the column 4 to continuously monitor the distance between the fixed position of the column 4 and the corresponding position of the support 1. The distance monitoring module 2 is uploaded to the cloud for comprehensive analysis of the monitoring data of the pressure monitoring module 2. If the overall offset of the support 1 and the limit frame 3 around the outer wall of the pipe body 2 may cause changes in the extrusion force at the position of the movable head 6, and if the bottom of the column 4 sinks, it may also cause changes in the extrusion force at the position of the movable head 6. Therefore, by comprehensively analyzing the data of the distance monitoring module 2 and the position data of the movable head 6, the pressure coefficient 2 is generated, so as to improve the accuracy and applicability of the generation of the pressure coefficient 2, and further improve the accuracy of calculating the position evaluation coefficient of the laying rack.

[0047] Calculation logic of the pressure coefficient 2:

[0048] Step 1: Data collection. Continuously collect the extrusion force data P2 of the pressure monitoring module 1 and the distance data D2 of the distance monitoring module 1.

[0049] Step 2: Using P2 and D2 as input features, construct the feature matrix X2, and prepare the target value t2 of the corresponding pressure coefficient two. Similarly, divide the data set into a training set and a test set;

[0050] Step 3: Select the same type of kernel function, initialize a new Gaussian process regression model, use X2 and y2 of the training set to train the model, and determine the parameters of the kernel function by maximizing the marginal likelihood estimation;

[0051] Step 4: After preprocessing the real-time collected P2 and D2 data, obtain the input vector x′ new , and input it into the trained model to obtain the predicted pressure coefficient two PC2 and the predicted variance

The connecting piece one 10 is made of an elastic material to disperse the pressure above between adjacent laying frames to both sides of the pipe body 2 through the cross-set connecting piece one 10 at the top, so as to improve the overall bearing capacity of multiple groups of laying frames.

The connecting part one 10 is made of an elastic material, so as to disperse the pressure above between adjacent laying frames to both sides of the pipe body 2 through the cross - arranged connecting parts one 10 at the top, thereby improving the overall bearing capacity of multiple groups of laying frames. The connecting part one 10 can be selected from elastic materials with deformation ability such as elastic connecting strips, cloth strips, elastic connecting nets, mesh cloth, fishing nets, etc. Only the elastic connecting strip is taken as an example in the drawings.

[0055] In the present invention, two cross - distributed connecting parts two 11 are arranged on both sides of the pipe body 2 between adjacent groups of laying frames.

The connecting part two 11 can be selected from elastic materials with deformation ability such as elastic connecting strips, cloth strips, elastic connecting nets, mesh cloth, fishing nets, etc. Only the elastic connecting strip is taken as an example in the drawings. By connecting the limiting frame 3 and the fixed head 5 in adjacent laying frames through the connecting part two 11, when the position between adjacent laying frames is subjected to a downward pressure from above, the pressure can be dispersed to the limiting frame 3 and the fixed head 5, reducing the load on the limiting frame 3 while dispersing the working force, thereby avoiding excessive damage to the outer wall of the pipe body 2 and further improving the overall bearing capacity of multiple groups of laying frames in use.
