Description

Technical Field

[0001] The invention relates to the field of narrow space detection, and in particular to a screw-in narrow environment detection device. Background Art

[0002] Cavitation refers to the formation of bubbles in the liquid due to the pressure drop below the vaporization pressure of the liquid during the flow of the fluid. The bubbles then collapse rapidly in the high-pressure area, and the released energy generates shock waves, causing corrosion and wear to equipment such as pipes, pumps, and valves. This phenomenon is particularly serious at the contact point between the crown of the runner and the lower part of the top cover of the hydro-turbine generator set, which directly affects the operating efficiency and life of the equipment. The traditional detection method relies on planned maintenance, and the cavitation condition is checked by lifting the top cover. This method is costly, inefficient, and lacks specificity.

[0003] In view of the damage caused by cavitation to equipment and the limitations of traditional detection methods, the current technical problem is how to develop a device that can effectively detect cavitation at the contact point between the upper crown of the turbine generator wheel and the lower part of the top cover without hanging the ceiling cover. Specifically, the following technical problems need to be solved: First, how to perform accurate cavitation detection in the small space inside the equipment.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In view of the problems of difficult detection in narrow spaces, limited image acquisition capabilities, and improved data processing efficiency in the prior art, the present invention proposes a screw-in narrow environment detection device. The main components of the screw-in narrow environment detection device are a steel wire stable screw-in device, a detection double-line receiving and sending device 5, and a data analysis server. A number of innovative technologies and measures are adopted to address the three major difficulties of the narrow size of the internal top cover detection area of ​​the Francis turbine generator set, the image acquisition quality, and the large amount of data analysis.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Reference Figures 1 to 11 As shown, an embodiment of the present invention provides a screw-in narrow environment detection device, including a wire screw-in device 1, a detection double-line receiving and sending device 5, a detection device 8 and a data analysis server. Figure 1 As shown, the steel wire screwing device 1 is used to stably screw the alloy steel wire guide wire 2 into the slit to be tested, and play the slit wall guiding function and guiding role. The steel wire screwing device 1 is based on the stable screwing action of the alloy steel wire guide wire 2, and cooperates with the slit wall guiding function of the guide ball to accurately and stably screw the alloy steel wire guide wire 2 into the predetermined position and play a guiding role. The detection double-line receiving and sending device 5 uses two alloy steel wire detection wires 6 and three shape memory metals 7, and accurately controls the movement of the detection equipment through flexible precision control and positioning function in the slit. Three shape memory metals 7 are used in the detection device 8. They adjust their angles through the pulling position of the alloy steel wire detection wire 6, thereby realizing the precise positioning of the detection equipment. By accurately pulling the two alloy steel wire detection wires 6, the angle change of the shape memory metal 7 is controlled. The main function of the data analysis server is to analyze, process, splice and three-dimensionally model the collected image information, and visualize the processed data. In-depth analysis and processing of image information through the data analysis server can not only improve the quality and availability of images, but also provide accurate data support for subsequent applications.

[0039] Specifically, Figures 2 to 6As shown, the steel wire screw-in device 1 includes a screw-in mechanism frame 101, a wire feeding mechanism 102, a rotation module 105, a winding module 106, a first control module 107 and a first motor drive module 108 group. A first control box 103 is fixedly connected to the screw-in mechanism frame 101, and the wire feeding mechanism 102 is installed on one side (front side) of the first control box 103. The left and right sides of the first control box 103 are respectively the first control module 107 and the first motor drive module 108. The first motor drive module 108 provides driving force for the wire feeding mechanism 102. A drive motor is arranged in the first motor drive module 108. The drive motor is connected to the wire feeding mechanism 102 through a transmission system, and the transmission system is arranged in the first control box 103. The first control module 107 is connected to the transmission system to control the operation of the transmission system. A rotating motor 104 is fixedly installed above the screw-in mechanism frame 101, and the rotating motor 104 drives the rotating module 105 located above it to rotate, and the operation of the rotating motor 104 is also controlled by the first control module 107. Two brackets are fixedly connected above the rotating module 105, and the winding modules 106 are rotated on the two brackets. The alloy steel wire guide wire 2 is wound on the winding modules 106, and one end of the alloy steel wire guide wire 2 passes through the center of the rotating module 105 and the rotating motor 104 to enter the wire feeding mechanism 102, and then passes through the center of the bottom of the steel wire screw-in frame.

[0040] The winding module 106 is responsible for maintaining the stability of the steel wire rotation during the steel wire release process, preventing the steel wire from jumping or shifting due to tension changes or external interference. At the same time, the winding module 106 can also work in conjunction with the wire feeding module to ensure the stability and continuity of the steel wire during the conveying process.

[0041] The wire feeding mechanism 102 is a device for extracting the alloy steel wire guide wire 2 from the winding module 106 and delivering it to the measuring hole. It needs to have precise control capabilities so as to adjust the conveying speed and length of the steel wire according to actual needs. The guide head 4 is located at the head of the screwed-in steel wire. The guide head 4 can help the steel wire pass smoothly through narrow or curved channels and reduce damage caused by friction or collision. The endoscopic clamp 3 is an auxiliary tool in the entire device. It is mainly used to find the guide head 4 at the end of the alloy steel wire guide wire 2 and remove the guide head 4. The endoscopic clamp 3 needs to have sufficient clamping force and precision to ensure that it can stably clamp the guide head 4 and remove the alloy steel wire guide wire 2 from the measuring hole.

[0042] like Figure 4As shown, the wire feeding mechanism 102 includes a wire feeding gear 10205 and a wire feeding guide wheel 10206 which are rotatably connected to the front side of the first control box 103. The rotating shafts at the centers of the wire feeding gear 10205 and the wire feeding guide wheel 10206 penetrate into the interior of the first control box 103 and connect with the transmission system, and provide driving force through the first motor drive module 108. A wire feeding channel for transmitting the alloy steel wire guide wire 2 is formed between the wire feeding gear 10205 and the wire feeding guide wheel 10206. Specifically, the outer periphery of the wire feeding gear 10205 is evenly distributed with a plurality of teeth, which are used to form strong friction with the alloy steel wire guide wire 2 to drive the alloy steel wire guide wire 2 to move forward and backward. The outer peripheral surface center of the wire feeding guide wheel 10206 is provided with a guide groove adapted to the alloy steel wire guide wire 2. The wire feeding gear 10205 and the wire feeding guide wheel 10206 clamp the alloy steel wire guide wire 2 between the two, and the alloy steel wire guide wire 2 is transported by the two rotating in opposite directions.

[0043] A limit block 10201 and a limit block 10202 for limiting the running direction of the alloy steel wire guide line 2 are respectively provided above and below the wire feeding gear 10205 and the wire feeding guide wheel 10206, wherein the limit block 10202 is stably fixed to the side of the first control box 103 by two bolts, and the limit block 10201 is rotatably connected to the side of the first control box 103 by a pin shaft, and the pin shaft is located at one end of the limit block 10201. Therefore, the other end of the limit block 10201 is a movable end, and the movable end is elastically connected to the top of the limit block 10201 to realize the adaptive adjustment function of the limit block 10201. Specifically, a positioning rod is vertically connected between the movable end of the limit block 10201 and the limit block 2 10202, one end of the positioning rod is fixed to the limit block 10202 by a nut, and the other end freely passes through the limit block 10201, so that the limit block 10201 can slide on the positioning rod. In order to enable the limit block 10201 to slide freely, it can be understood that a movable hole with an inner diameter much larger than the positioning rod is opened on the limit block 10201, and an adaptive spring 10207 is sleeved on the positioning rod between the limit block 10201 and the limit block 2 10202, one end of the adaptive spring 10207 is fixed to the bottom of the limit block 10201, and the other end is connected to the nut above the limit block 2 10202. The limiting sleeve 10203 and the limiting sleeve 2 10204 are respectively installed on the limiting block 10201 and the limiting block 2 10202 through nuts, and the alloy steel wire guide line 2 passes through the limiting sleeve 1 10203, the wire feeding guide wheel 10206 and the wire feeding gear 10205, and the limiting sleeve 2 10204 in sequence.

[0044] In the above embodiment, on the one hand, the adaptive spring 10207 functions to support the movable end of the first limiting block 10201; on the other hand, it serves as a certain buffer to absorb the vibration and deformation of the first limiting block 10201 and the second limiting block 10202 caused by the screwing-in of the alloy steel wire guiding wire 2, as well as to slow down the impact force; on the one hand, it also has the function of stabilizing the pre-tightening pressure to ensure the stability of the screwing-in pressure.

[0045] As Figure 7 shown, the double-wire sending and receiving device 5 includes a sending and receiving mechanism frame 501, a wire winding module one 502, a wire winding module two 503, a second control module 504, a second motor drive module 505, a wire feeding mechanism one 506, a wire feeding mechanism two 507, and a wire guiding member 508.

[0046] Specifically, a second control box is fixed above the sending and receiving mechanism frame 501, and the second control module 504 and the second motor drive module 505 are respectively arranged on both sides of the second control box. Their structures and connection relationships are the same as those of the steel wire screwing-in device 1 and will not be elaborated here.

[0047] On the front side of the second control box, there are two wire feeding mechanisms 102, one on the left and one on the right. Above the wire feeding mechanism one 506, the wire winding module one 502 is correspondingly arranged. Above the wire feeding mechanism two 507, the wire winding module two 503 is correspondingly arranged. Both the wire winding module one 502 and the wire winding module two 503 are supported by U-shaped brackets. In this embodiment, the wire winding module one 502 and the wire winding module two 503 serve as the storage and storage devices for the alloy steel wire detection line 6. Their designs fully consider the length, diameter, and material of the steel wire to ensure the safe and stable storage and release of the steel wire. The structures of the wire feeding mechanism one 506 and the wire feeding mechanism two 507 can adopt the structure of the wire feeding mechanism 102 in the steel wire screwing-in device 1 and will not be elaborated here.

[0048] Below the wire feeding mechanism one 506 and the wire feeding mechanism two 507, there is a wire guiding member 508. The wire guiding member 508 has two wire guiding channels corresponding to the upper limiting sleeve outlets of the wire feeding mechanism one 506 and the wire feeding mechanism two 507, and a wire guiding inlet that combines the two wire guiding channels into one.

[0049] The wire feeding mechanism 1 506 and the wire feeding mechanism 2 507 are the core components of the retracting and releasing control of the alloy steel wire detection line 6. They are connected to a servo motor. By accurately controlling the speed and direction of the servo motor, the device can realize the rapid retracting and releasing and fine-tuning functions of the steel wire, and can adapt to narrow working environments and precise operation requirements to ensure that the steel wire is always in the best working state. The alloy steel wire detection line 6 connects and controls the shape memory metal 7, which has high strength and toughness and can withstand certain tension and torsion. Through the connection with the shape memory metal 7, the alloy steel wire detection line 6 can realize the precise adjustment of the position and angle of the shape memory metal 7, thereby ensuring that the detection device can accurately reach the target position. The shape memory metal 7 is a carrier carrying the detection device, which has a shape memory function and can change its shape when subjected to external stimulation so as to enter a narrow area and return to its original state after the stimulation disappears. This enables the shape memory metal 7 to adapt to various complex detection environments and achieve precise positioning and angle adjustment through the control of the alloy steel wire detection line 6.

[0050] The working process and working principle of the embodiment of the present invention are as follows:

[0051] First, the working process of the steel wire screwing device 1. The first step of the cavitation state detection work is to screw the alloy steel wire detection line 6 into the measuring hole, which drives the winding drum to rotate, guides the alloy steel wire guide line 2 to complete the rotation of the line, and keeps the alloy steel wire guide line 2 close to the side wall of the detection area and moves forward. During the entire cavitation detection process, the rotating module 105 drives the winding module 106 to rotate and guides the alloy steel wire detection line 6 to the detection area. The rotation of the winding module 106 allows the alloy steel wire guide line 2 to be guided to the corresponding position to prepare for subsequent detection operations. The screwing process requires the rotating module 105 to accurately control the rotation speed and direction of the winding module 106 to ensure that the alloy steel wire detection line 6 can accurately enter the area to be detected. Then the rotating module 105 continues to drive the rotation of the alloy steel wire detection line 6 to ensure that the alloy steel wire detection line 6 can move forward close to the side wall of the detection area. By accurately controlling the rotating module 105, the alloy steel wire detection line 6 can smoothly move forward along the side wall of the detection area and complete the rotation process of the alloy steel wire detection line 6. When the wire screwing device 1 delivers the alloy steel wire detection line 6 to the next measuring hole, the operator uses the endoscope clamping forceps 3 to clamp out the alloy steel wire detection line 6 that has reached the measuring hole and connect it to the wire reel module. Then the wire reel module smoothly retracts the cable to achieve the connection between the two detection holes. Figure 8 shown.

[0052] Then, the operator connects the alloy steel wire detection line 6 to the alloy steel wire guide line 2, and installs the alloy steel wire guide line 2 taken out by the clamp on the winding module 106 of the wire screw-in device 1, starts the winding module 106 to retract the alloy steel wire guide line 2, and sends the detection double wires (two alloy steel wire detection lines 6) to the inside of the top cover, as shown in FIG. Fig. 9 When the winding module 106 completely retracts the alloy steel wire guide wire 2, the operator can transfer the steel wire screwing device 1 to the next set of measuring holes through the transfer vehicle to continue the process of screwing the alloy steel wire detection wire 6.

[0053] Entering the process of screwing in the alloy steel wire detection line 6, the operator places a detection double-line sending and receiving device 5 on each of the two measuring holes, and fixes the two ends of the detection double line on the winding module 106 of the detection double-line sending and receiving device 5. The detection device 8 is adjusted in real time by the detection double-line sending and receiving device 5 to retract and release the detection double line, thereby realizing the detection of the cavitation condition of the top cover. The cavitation state detection device 8 uses a camera and an optical fiber that guides the line laser to shoot the top cover area and three-dimensional structural information, capture clear and accurate image data, and transmit the acquired image data to an external server through a transmission line. The server pre-processes the image, including noise filtering, contrast enhancement, and edge detection steps to improve the image quality and recognition. The server calibrates the size of the cavitation condition displayed in the image according to the curved laser line to reflect the cavitation amount of the top cover. Specifically, Fig.10 shown.

[0054] Finally, after the image acquisition is completed, the operator cuts the double-wire detection line of the double-wire detection receiving and sending device 5, and starts the winding device of another double-wire detection receiving and sending device 5 to retract the double-wire detection line, such as Fig.11 Then the operator uses the transfer trolley to transfer the alloy steel wire detection line 6 into the device and the detection double-line receiving and sending device 5 to the next section to be detected and repeats the process four times to detect the cavitation state of the complete top cover.

[0055] Compared with the prior art, the embodiments of the present invention at least disclose the following beneficial effects:

[0056] 1. The screw-in narrow environment detection device can effectively detect cavitation status in a small space, avoiding the high cost and low efficiency caused by the need to disassemble equipment in traditional methods, and achieving efficient detection.

[0057] 2. Accurate positioning is achieved through the combination of the wire screw-in device 1 and the detection double-line receiving and sending device 5, ensuring that the detection equipment can accurately and stably reach the predetermined position, thereby improving the accuracy of the detection.

[0058] 3. The data analysis server conducts in-depth analysis and processing of the collected image information, and can generate high-quality three-dimensional models, provide accurate data support, and help determine whether Class A maintenance is required.

[0059] 4. The design of the device takes into account the narrow and complex working environment, and adopts a combination of shape memory metal 7 and alloy steel wire to ensure flexibility and reliability under various conditions, thereby adapting to various complex environments.

[0060] 5. Through the camera and laser technology, the image data of the top cover area can be obtained in real time, processed and visualized, which improves the timeliness and effectiveness of monitoring.

[0061] 6. Reduce the risk of fluid leakage and system failure caused by equipment damage, effectively improve the safety of the system, and enhance the protection of personnel and the environment.
