[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a nondestructive testing device for concrete anti-seepage walls of water conservancy projects, which has the following beneficial effects:

[0018] 1. The nondestructive detection device for concrete anti-seepage walls of water conservancy projects adjusts the support range of the support assembly through the adjustment assembly. First, the manual adjustment mechanism adjusts the synchronous adjustment rod to move outward, and the synchronous adjustment rods on both sides simultaneously pull the force storage tension spring outward, so that the force storage tension spring is in a stretched and force storage state, and then the position of the synchronous adjustment rod is fixed by the limiting mechanism, and the trigger rod in the anti-drop assembly is further connected to the limiting mechanism, and the other end of the anti-drop assembly is placed above the concrete anti-seepage wall. At this time, the support assembly is located between the two concrete anti-seepage walls, that is, the driving assemblies at the ends of the bent rods on both sides of the electronic compartment are in contact with the concrete anti-seepage walls respectively, so as to avoid damage to the concrete anti-seepage wall surface when the detection device detects the concrete anti-seepage wall surface, thereby realizing nondestructive detection of the concrete anti-seepage wall surface.

[0019] 2. The nondestructive detection device for concrete anti-seepage walls of water conservancy projects uses the gravity of the detection device. When the friction between the driving component and the concrete anti-seepage wall is too small, the detection device has a downward tendency, and the anti-drop component moves relative to the concrete anti-seepage wall until it contacts the concrete anti-seepage wall. The trigger rod prompts the limiting mechanism to release the fixation of the synchronous adjustment rod. At this time, the synchronous adjustment rod loses its restriction, and under the action of the force storage tension spring in the force storage state, the synchronous adjustment rod is driven to move toward the middle, and then the bending rod is driven to shrink toward the middle. When the bending rod shrinks toward the middle, the pressure of the driving component on the concrete anti-seepage wall is increased, thereby realizing the friction between the driving component and the concrete anti-seepage wall, so that the device can move smoothly between the concrete anti-seepage walls; it solves the problem that the same equipment cannot be used for detection when detecting concrete anti-seepage walls of different widths.

[0020] 3. The nondestructive detection device for concrete anti-seepage walls of water conservancy projects uses a force-storage tension spring arranged in the inner cavity of a synchronous adjustment rod. After the connection rod and the telescopic cylinder are fixed, the force-storage tension spring is manually charged. The synchronous adjustment rods on both sides move to both sides at the same time, and drive the distal ends of the force-storage tension springs to move to both sides, so that the force-storage tension springs are stretched and charged. Through the force-storage tension springs, the detection device automatically adjusts its tension after being placed between concrete anti-seepage walls.

[0021] 4. The nondestructive testing device for concrete anti-seepage walls of water conservancy projects uses a stepped restriction plate in a restriction mechanism. After the force-storage tension spring completes force storage, the stepped restriction plate is placed between two synchronous adjustment rods through an installation groove, so that the maximum width part of the stepped restriction plate is against the synchronous adjustment rod, and the synchronous adjustment rod is fixed, that is, the force-storage tension spring in the force storage state is fixed; when the device is released, the device moves downward under the action of the gravity of the device, and the horizontal plate moves relative to the concrete anti-seepage wall until it contacts the concrete anti-seepage wall, and then the baffle is pulled to move by the vertical plate and the trigger rod, so that the stepped restriction plate is away from the synchronous adjustment rod, and then the synchronous adjustment rod is released from the fixed state and can move to the middle under the tension of the force-storage tension spring; the problem that it is inconvenient to adjust the tension of the support assembly between the concrete anti-seepage walls is solved.

The other end of the manual adjustment rod 533 is connected to the synchronous adjustment rod 51. The driving rod 532 is driven by the adjusting gear 531 in the manual adjustment mechanism 53, and the driving rod 532 moves to both sides, and at the same time drives the synchronous adjustment rod 51 to move to both sides. The synchronous adjustment rod 51 pulls the force storage spring 52 for force storage.

[0044] Working principle: When in use, first adjust the support range of the support component 4 through the adjustment component 5, first the manual adjustment mechanism 53 adjusts the synchronous adjustment rod 51 to move outward, and the synchronous adjustment rods 51 on both sides simultaneously pull the force storage tension spring 52 outward, so that the force storage tension spring 52 is in a stretched force storage state, and the adjustment gear 531 in the manual adjustment mechanism 53 drives the driving rod 532, and the driving rod 532 moves to both sides, and at the same time drives the synchronous adjustment rod 51 to move to both sides, and the synchronous adjustment rod 51 pulls the force storage tension spring 52 for force storage, and when the stepped limiting plate 541 is against between the synchronous adjustment rods 51, the adjustment gear can be released. 531; before adjustment, the connecting rod 55 in the adjustment assembly 5 is connected by interference with the raised portion inside the telescopic cylinder 56. The specific connection method is that when the telescopic cylinder 56 rotates relative to the connecting rod 55, the connecting rod 55 is connected by interference with the raised portion. This structure is a prior art and is not described in detail here; when the connecting rod 55 moves relative to the telescopic cylinder 56 to a suitable position (the bending rod 42 is opened to the driving roller 31 at its end in contact with the concrete anti-seepage wall), the connecting rod 55 is driven to rotate relative to the telescopic cylinder 56, so that the connecting rod 55 is connected by interference with the raised portion inside the telescopic cylinder 56. At this time, the connecting rod 55 and the telescopic cylinder 56 are fixed;

[0045] Then, through the force storage tension spring 52 arranged in the inner cavity of the synchronous adjustment rod 51, after the connection rod 55 and the telescopic cylinder 56 are fixed, the force storage tension spring 52 is manually charged, and the synchronous adjustment rods 51 on both sides move to both sides at the same time, and drive the distal ends of the force storage tension spring 52 to move to both sides, so that the force storage tension spring 52 is stretched and charged;

[0046] Then, the position of the synchronous adjustment rod 51 is fixed by the limiting mechanism 54, and the trigger rod 61 in the anti-drop assembly 6 is further connected to the limiting mechanism 54, and the other end of the anti-drop assembly 6 is placed above the concrete anti-seepage wall; after the force storage tension spring 52 completes the force storage, the stepped limiting plate 541 in the limiting mechanism 54 is placed between the two synchronous adjustment rods 51 through the mounting groove 543, so that the maximum width part of the stepped limiting plate 541 is against the synchronous adjustment rod 51, and the synchronous adjustment rod 51 is fixed, that is, the force storage tension spring 52 in the force storage state is fixed;

[0047] In the above process, the movable base 43 in the support assembly 4 enables the bending rod 42 to swing relative to the mounting plate 41. Before adjusting the adjustment assembly 5 in the detection device, the bending rod 42 is in an open state by using the torsion spring 44 between the bending rod 42 and the mounting plate 41, wherein the two bending rods 42 on one side of the open state are connected together (such as Figure 1 The two bending rods 42 on the left and right sides are respectively connected together), when the two bending rods 42 on the upper side that can be relatively opened are adjusted by the adjustment assembly 5, the two bending rods 42 on the other side of the bottom follow the bending rods 42 connected thereto and move together;

[0048] At this time, the support component 4 is located between the two concrete anti-seepage walls, that is, the driving components 3 at the ends of the bent rods 42 on both sides of the electronic warehouse 1 are in contact with the concrete anti-seepage walls respectively; then the detection device is released, and through the gravity of the detection device, when the friction between the driving component 3 and the concrete anti-seepage wall surface is too small, the detection device has a downward trend, and the anti-drop component 6 moves relative to the concrete anti-seepage wall until it contacts the concrete anti-seepage wall, and then the limiting mechanism 54 is prompted to release the fixation of the synchronous adjustment rod 51 through the trigger rod 61, wherein when the device is released, under the action of the gravity of the device, the device moves downward, and the horizontal plate 63 moves relative to the concrete anti-seepage wall until it contacts the concrete anti-seepage wall, and then the baffle 542 is pulled to move by the vertical plate 62 and the trigger rod 61, so that the stepped limiting plate 541 is away from the synchronous adjustment rod 51, and then the synchronous adjustment rod 51 is released from the fixed state and can move to the middle under the tension of the storage tension spring 52;

[0049] At this time, the synchronous adjustment rod 51 loses its restriction, and under the action of the force storage tension spring 52 in the force storage state, the synchronous adjustment rod 51 is driven to move toward the middle, thereby driving the bending rod 42 to shrink toward the middle. When the bending rod 42 shrinks toward the middle, the pressure of the driving component 3 on the concrete anti-seepage wall is increased, thereby realizing the friction between the driving component 3 and the concrete anti-seepage wall, so that the device can move smoothly between the concrete anti-seepage walls, and the driving gear 72 is driven to rotate by the steering motor in the steering component 7, and the driving gear 72 drives the steering gear 73 to rotate, and the steering gear 73 adjusts the direction of the roller bracket 32, thereby adjusting the driving direction of the driving roller 31. The friction between the driving roller 31 in the driving component 3 and the concrete anti-seepage wall surface, driven by the dual-axis driving motor 33, causes the driving roller 31 to rotate at the bottom of the roller bracket 32, thereby enabling the device to move flexibly between the two concrete anti-seepage walls; avoiding damage to the concrete anti-seepage wall surface when the detection device detects the concrete anti-seepage wall surface, thereby realizing non-destructive detection of the concrete anti-seepage wall surface.
