Description

Technical Field

[0001] This application relates to the technical field of expansion joint measurement equipment, and in particular to a quantitative detection device for the change of expansion joints in water conservancy projects. Background Technique

[0002] Water conservancy projects play a role in controlling and allocating surface water and groundwater, and have great practical significance. In water conservancy projects, in order to improve the service life of water conservancy facilities and ensure the normal operation of water conservancy facilities, some expansion joints are often constructed. However, the expansion joints often change during use, so it is necessary to detect the expansion joints regularly.

[0003] After retrieval, the patent document with the application number CN202110662582.X discloses a detection device for the change of cracks and expansion joints in large water conservancy projects; the detection device includes a frame, two depth measurement mechanisms, a width measurement mechanism and a reading mechanism. The two depth measurement mechanisms are symmetrically arranged on both sides of the top of the frame and correspond to the crack positions of the frame. The width measurement mechanism is installed on one of the depth measurement mechanisms, and the reading mechanism is installed on the other depth measurement mechanism. The depth measurement mechanism includes an installation component and a depth measurement component. The installation component is installed on the top of the frame, and the depth measurement component is installed on the installation component and corresponds to the crack position of the frame. This device can synchronously detect the width and depth of the cracks and expansion joints in water conservancy projects at one time, with fast measurement speed and small error, which helps to reduce the labor intensity of work, and thus improves the practicability of this device.

[0004] Regarding the above-mentioned related technical features, the inventor believes that there are the following defects: First, due to environmental factors inside the expansion joints of large water conservancy projects, a layer of impurities often adheres to the side walls of the expansion joints, which will lead to inaccurate measurement of the change amount of the expansion joints; Second, the above device only simply measures the change of the expansion joints, but cannot effectively guide the subsequent actions, which is relatively single; Third, the operation is relatively cumbersome, affecting the detection efficiency of the change of the expansion joints. Summary of the Invention

[0005] In order to improve the accuracy of measuring the expansion joints and facilitate the subsequent maintenance of the problematic expansion joints, this application provides a quantitative detection device for the change of expansion joints in water conservancy projects.

The detection device includes a detection frame body, moving wheels, a cleaning mechanism, a measuring mechanism, and a marking mechanism. The moving wheels are arranged on the detection frame body to facilitate the movement of the detection frame body along the length direction of the expansion joint. The detection frame body has a starting end and a terminating end. The cleaning mechanism is arranged at the starting end and is used to clean the impurities on the inner wall of the expansion joint. The measuring mechanism is arranged on the detection frame body, between the starting end and the terminating end, and is used to detect the width of the expansion joint. The marking mechanism is connected to the measuring mechanism and is used to mark the corresponding position of the expansion joint according to the state of the measuring mechanism.

[0007] By adopting the above technical solution, when detecting the quantitative change of the expansion joint, move the detection frame body to the measurement position of the expansion joint, push the detection frame body, the detection frame body drives the cleaning mechanism to move, adjust the cleaning mechanism, and the cleaning mechanism cleans the impurities on the inner side wall of the expansion joint. At this time, the measuring mechanism moves to the position of the expansion joint cleaned by the cleaning mechanism, adjust the measuring mechanism, and the measuring mechanism detects the width of the expansion joint. If the state of the measuring mechanism does not change, the marking mechanism does not mark the expansion joint, indicating that the width of the expansion joint here is normal. If the state of the measuring mechanism changes, the measuring mechanism will drive the marking mechanism to move, and the marking mechanism will mark the expansion joint, so as to facilitate the subsequent staff to repair the expansion joint according to the situation of the expansion joint.

In the measuring state, under the action of the buckle assembly 45, the second measuring block 43 approaches the side of the expansion joint 6 (here only the case where the expansion joint 6 expands is described. Of course, the expansion joint 6 may have a problem of narrowing. When the expansion joint 6 has a narrowing problem, the measuring mechanism 4 cannot extend into the expansion joint 6, and this application does not consider this). The movement of the second measuring block 43 will drive the movement of the marking mechanism 5, so as to mark the abnormal area of the expansion joint 6.

[0055] In this embodiment, referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 , the buckle assembly 45 includes a buckle block 451, a buckle spring 452, a buckle rotating rod 453, and a buckle lock 454; one end of the buckle block 451 is rotatably connected to the detection frame 1 through the buckle spring 452, wherein the axial direction of the rotation axis of the buckle block 451 and the detection frame 1 is perpendicular to the movement direction of the detection frame 1; the buckle rotating rod 453 is connected to the second measuring block 43, and the buckle rotating rod 453 is slidably connected to the detection frame 1 and can rotate along its own axial direction. It can be understood that the movement of the second measuring block 43 can drive the buckle rotating rod 453 to slide on the detection frame 1; the buckle lock 454 is arranged on the buckle rotating rod 453; the buckle assembly 45 has a clamping state. Under the action of the second measuring block 43, the buckle rotating rod 453 drives the buckle lock 454 to approach the buckle block 451, and the buckle lock 454 is clamped with the buckle block 451.

[0056] Further, the buckle assembly 45 has a release state. When it is necessary to measure the change amount of the expansion joint 6, rotate the buckle lever 453. The rotation of the buckle lever 453 drives the rotation of the buckle lock 454. The rotation of the buckle lock 454 causes the buckle lock 454 to loosen from the buckle block 451. Under the action of the first spring 44, the second measuring block 43 approaches the side wall of the expansion joint 6 to measure the change amount of the expansion joint 6.

[0057] Furthermore, referring to Figure 5 , a buckle torsion spring 455 can also be sleeved on the lever of the buckle lever 453. When the buckle lever 453 rotates, it can automatically return under the action of the buckle torsion spring 455, and can quickly lock and unlock the second measuring block 43.

[0058] In some embodiments of the present disclosure, referring to Figure 2 , Figure 6 and Figure 9 , the marking mechanism 5 includes a plurality of identification components 51 arranged along the length direction of the detection frame 1, a control component 52 arranged corresponding to the identification components 51, and a driving component 53 for driving the movement of the control component 52; the control component 52 is connected to the second measuring block 43 through the driving component 53, and the driving component 53 drives the control component 52 to move under the movement of the second measuring block 43; the control component 52 is used to drive the movement of the identification components 51.

[0059] Specifically, due to the change in the width of the expansion joint 6, when the first measuring block 42 and the second measuring block 43 enter the expansion joint 6 (the first measuring block 42 abuts against the side wall of the expansion joint 6), the second measuring block 43 approaches the side wall of the expansion joint 6 under the action of the first spring 44. The movement of the second measuring block 43 drives the movement of the driving component 53, the movement of the driving component 53 drives the movement of the control component 52, and the movement of the control component 52 drives the movement of the identification components 51, so as to mark the position where the expansion joint 6 is located for the subsequent treatment by the staff.

[0060] In some embodiments of the present disclosure, the control assembly 52 includes a control rotating rod 521, a plurality of second bevel gear sets 522, a control screw 523, a control block 524, and a control switch 525; the control rotating rod 521 is rotatably connected to the detection frame body 1, and the axial direction of the control rotating rod 521 is the same as the moving direction of the detection frame body 1; the driving assembly 53 is connected to the control rotating rod 521, and the driving assembly 53 is used to drive the control rotating rod 521 to rotate; the plurality of second bevel gear sets 522 are evenly distributed along the length direction of the control rotating rod 521; the control screw 523 is connected to the corresponding second bevel gear set 522; the control block 524 is threadedly connected to the control screw 523 and is slidably connected to the detection frame body 1; the control switch 525 is arranged on the detection frame body 1, the control switch 525 is correspondingly arranged with the control block 524, and the control block 524 can contact the control switch 525. Among them, the control assembly 52 is turned on or off under the action of the control switch 525, and the control switch 525 is used to control the movement of the identification assembly 51.

[0061] As an example, refer to Figure 6, three sets of second bevel gear sets 522 can be arranged along the axial direction of the control screw 523. It can be understood that in other embodiments, the number of the second bevel gear sets 522 is not limited to this. Three control screws 523 are correspondingly arranged for the three sets of second bevel gear sets 522. Three control blocks 524 are correspondingly arranged on the three control screws 523, and control switches 525 correspondingly arranged with the three control blocks 524 are arranged on the detection frame 1. Among them, the distances between the three control blocks 524 and the control switches 525 are different, which means that when the three control screws 523 rotate, there is a phenomenon that some control blocks 524 are in contact with the control switches 525, and some control blocks 524 are not in contact with the control switches 525. Specifically, when the control screw 523 rotates a small number of turns, the control block 524 closer to the control switch 525 is in contact with the control switch 525, and a control signal is formed. This control signal controls the corresponding identification component 51 to move, and the corresponding identification component 51 marks the expansion joint 6 (this mark is that the change of the expansion joint 6 is within an acceptable range); when the control screw 523 rotates a moderate number of turns, some control blocks 524 are in contact with their corresponding control switches 525, and the control switches 525 send out control signals. This control signal drives the control component 52 to move, and the control component 52 drives the identification component 51 to move, and the corresponding identification component 51 marks the expansion joint 6 (this mark is that the change of the expansion joint 6 should be taken seriously); when the control screw 523 rotates a large number of turns, all control blocks 524 are in contact with their corresponding control switches 525, and the control switches 525 send out control signals. This control signal drives the control component 52 to move, and the control component 52 drives the identification component 51 to move, and the corresponding identification component 51 marks the expansion joint 6 (this mark is that the change of the expansion joint 6 should be repaired). With such an arrangement, the change amount of the expansion joint 6 can be accurately judged, and subsequent further repairs can be guided.

[0062] As an example, refer to Figure 6 、 Figure 9 , the second bevel gear set 522 can include a second driving bevel gear 5221 and a second driven bevel gear 5222; among them, the second driving bevel gear 5221 is fixed on the control rotating rod 521 by key connection, the second driven bevel gear 5222 is fixed on the control screw 523 by key connection, and the second driving bevel gear 5221 meshes with the second driven bevel gear 5222.

[0063] In some embodiments of the present disclosure, refer to Figure 2 、 Figure 3 and Figure 4, the driving component 53 includes a driving block 531, a driving rack 532, and a driving gear 533; the driving block 531 is connected to the second measuring block 43; the driving rack 532 is arranged on the driving block 531, and the moving direction of the driving rack 532 is the same as the width direction of the expansion joint 6; the driving gear 533 is arranged on the control rotating rod 521, and the driving gear 533 meshes with the driving rack 532. Specifically, when the width of the expansion joint 6 causes the second measuring block 43 to change, the second measuring block 43 moves, the movement of the second measuring block 43 drives the driving rack 532 to move, the movement of the driving rack 532 drives the driving gear 533 to move, the rotation of the driving gear 533 drives the control rotating rod 521 to rotate, the rotation of the control rotating rod 521 drives the multiple second bevel gear sets 522 arranged thereon to move, the movement of the second bevel gear sets 522 causes the control screw 523 to rotate, the rotation of the control screw 523 causes the control block 524 to move, and the control block 524 contacts the control switch 525, thereby achieving the purpose of driving the marking component 51 to move.

[0064] In some embodiments of the present disclosure, refer to Figure 6 , Figure 10 , the marking component 51 includes a marking screw 511, a marking motor 512, a marking block 513, and a marking pen 514; the marking screw 511 is rotatably connected to the detection frame 1, and the axial direction of the marking screw 511 is perpendicular to the moving direction of the detection frame 1; the marking block 513 is threadedly connected to the marking screw 511 and is slidably connected to the detection frame 1; the marking pen 514 is connected to the marking block 513 and can contact the surface of the expansion joint 6; the marking motor 512 is turned on under the action of the control component 52 and is used to drive the marking screw 511 to rotate.

[0065] It can be understood that by turning on the control switch 525, the control switch 525 sends a signal to control the movement of the marking motor 512. This technology is well-known to those skilled in the art and will not be elaborated in this application.
