Description

Technical Field

[0001] The present invention relates to the technical field of dam cavity detection, and in particular to a dam cavity detection device. Background Art

[0002] The potential for dam cavity damage is caused by a variety of factors. First, incomplete foundation clearing during dam construction can lead to the presence of deep, hard blocks in the soft base layer, insufficient compaction, sandy layers, loose joints, and culverts that haven't been thoroughly removed. Second, post-dam construction can lead to the formation of burrows inhabited by termites, rats, badgers, and other organisms, as well as decaying crevices in plant roots and organic matter.

[0003] Most dam failures are caused by hidden dangers within the dam structure. However, these hazards are often difficult to detect on the surface, often buried at depth. To identify these hazards, there are three methods: first, cone probing; second, geophysical exploration; and third, regular observation. These hazards are particularly noticeable during high water levels during flood season, such as wet areas on the back slope, high outflow points, piping, and leaks. These are all precursors to dam structure hazards.

[0004] Furthermore, termite control in water conservancy projects often involves grouting nests. Before grouting, the nest's location is typically probed using a traditional cone probe, using nest indicators. This involves hammering a cone with a conical bottom into the soil. The probe's results are determined by the operator's feel, requiring high levels of accuracy and resulting in low efficiency.

[0005] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0032] Example 1

[0033] like Figures 1 to 3 , a dam cavity detection device of this embodiment includes:

[0034] A first detection rod 10;

[0035] The rotation drive module 20 includes a first drive device 21 connected to the lower end of the first detection rod 10, a second detection rod 22 connected to the output end of the first drive device 21, and a drill bit 23 fixed to the lower end of the second detection rod 22;

[0036] The pressure detection module 30 includes a pressure sensor 31 provided at the lower end of the second detection rod 22, a pressure rod 32 that moves vertically below the pressure sensor 31, a pressure plate 33 that can abut against the pressure sensor 31 at the upper end of the pressure rod 32, and a spring 34 that is provided below the drill bit 23 at the lower end of the pressure rod 32. The spring 34 is sleeved on the outside of the pressure rod 32 and is used to drive the pressure rod 32 to return to its original position downward.

[0037] The visual detection module 40 includes at least one micro camera 41 disposed in the second detection rod 22 . The second detection rod 22 is provided with a through hole 221 for the micro camera 41 to shoot outward.

[0038] The dam cavity detection device of this embodiment is suitable for detecting the position of the cavity 110 before grouting of the ant nest. A first driving device 21 is connected to the lower end of the first detection rod 10, a second detection rod 22 is connected to the lower end of the first driving device 21, and a drill bit 23 is connected to the lower end of the second detection rod 22. Before detection, the exposed features of the termites are first found, and detection is performed around the exposed features. The drill bit 23 is driven by the first driving device 21 to gradually drill into the soil of the dam 100. When the drill bit 23 drills into the position of the ant nest cavity 110, the spring 34 pushes the drill bit 23 to drill into the ant nest cavity 110. Under the action, the pressure rod 32 is reset downward, and the pressure of the pressure plate 33 at the upper end of the pressure rod 32 on the pressure sensor 31 changes. Since the pressure sensor 31 detects the pressure change, the micro camera 41 in the second detection rod 22 is used to photograph the position, and the photographed image is transmitted to a terminal display device such as a mobile phone through wireless communication. The staff can intuitively determine whether the position is an ant nest cavity 110, thereby improving the detection accuracy; and by drilling a hole through the drill bit 23, the first detection rod 10 is easier to extend into the hard soil for detection, thereby improving the detection efficiency.

[0039] This embodiment uses a spring 34 as an elastic member, which is only one of the better implementation methods. When the drill bit 23 has no pressure, the spring 34 drives the pressure rod 32 to reset downward, so that the pressure plate 33 no longer presses the pressure sensor 31. At this time, the pressure value detected by the pressure sensor 31 is 0; and during the drilling process, due to the pressure of the pressure rod 32, the spring 34 is forced to be compressed and deformed, so that the pressure plate 33 generates pressure on the pressure sensor 31. At this time, the pressure sensor 31 detects a pressure value greater than 0; through the pressure changes in the two states, the operator can make a quick judgment and improve the detection efficiency.

[0040] Furthermore, in this embodiment, the upper end of the first detection rod 10 is detachably connected to at least one third detection rod 60 , and the detachable connection can be achieved by a threaded connection. By providing the third detection rod 60 , the detection depth can be extended.

[0041] Furthermore, a light-transmitting protective cover 222 is fixed to the outward end of the through hole 221. The light-transmitting protective cover 222 can be a glass cover and fixed to the outward end of the through hole 221 by glue such as glass glue, which can prevent dirt or water from contaminating the micro camera 41.

[0042] The visual detection module 40 also includes an angle adjustment module 50 for adjusting the angle of the micro camera 41. The angle adjustment module 50 includes a second driving device 51 fixed in the second detection rod 22, a screw 52 connected to the output shaft of the second driving device 51, a screw sleeve 53 threadedly matched with the screw 52, a rotating seat 54 fixed to the outside of the screw sleeve 53, a rotating shaft 55 fixed in the second detection rod 22, a swing arm 56 fixed to one end of the micro camera 41 and the middle of which is rotatably matched with the rotating shaft 55, and two ends respectively connected to the rotating seat. 54. The connecting rod 57 hinged to the swing arm 56 can adjust the shooting angle of the micro camera 41 through the angle adjustment module 50, so that the internal structure of the drilling position can be seen more accurately. The specific adjustment principle is: the screw 52 is driven to rotate by the second drive device 51, and the screw 52 then drives the screw sleeve 53 to move along the axial direction of the screw 52. The screw sleeve 53 drives the connecting rod 57 to swing, and the connecting rod 57 drives the swing arm 56 to swing. The swing arm 56 is connected to the micro camera 41, so that the micro camera 41 can adjust the angle. The structure is ingenious.

[0043] There are two micro cameras 41 , which are respectively located at the left and right ends of the inner side of the second detection rod 22 , so that they can take pictures in both left and right directions, so that the operator can observe the internal structure of the position more intuitively.

[0044] The first driving device 21 can be a motor. The first detection rod 10 is provided with a first power storage device 11 for supplying power to the first driving device 21. The second detection rod 22 is provided with a second power storage device 223 for supplying power to the second driving device 51 and the micro camera 41. Both the first power storage device 11 and the second power storage device 223 can be rechargeable battery packs. The first detection rod 10 has a charging interface electrically connected to the first power storage device 11. The second detection rod 22 has a charging interface electrically connected to the second power storage device 223. The end of the charging interface is provided in an openable sealed The cover, the connection position of the first detection rod 10 and the second detection rod 22 is threaded. When the power storage device 61 needs to be charged, the sealing cover can be opened and the charging cable can be plugged into the charging interface to charge the first power storage device 11 and the second power storage device 223. The electrical connection method between the first driving device 21 and the first power storage device 11 and the electrical connection method between the second driving device 51, the micro camera 41 and the second power storage device 223 can be connected by conventional wires, and the first power storage device 11 and the second power storage device 223 are also respectively equipped with circuit boards for control circuits.

[0045] Example 2

[0046] Please refer to Figures 4 to 6 Compared with Example 1, this embodiment is different in that:

[0047] The dam cavity detection device also includes a chassis 70 with a control panel 71 at the upper end, a telescopic drive device 80 arranged on the inner side of the chassis 70, and a plurality of tripod assemblies 90 detachably fixed to the bottom of the chassis 70. The telescopic drive device 80 can adopt an electric cylinder to drive the first detection rod 10 and other components at the lower end of the first detection rod 10 to descend through the telescopic drive device 80, and cooperate with the drilling of the drill bit 23 to achieve rapid drilling.

[0048] The micro camera 41 and the pressure sensor 31 transmit information to the control panel 71 via a wireless communication module. The wireless communication module can be implemented using existing wireless communication technology, which will not be described in detail below.

[0049] The output end of the telescopic drive device 80 is detachably connected to the upper end of the detection rod 10, and the upper end of the third detection rod 60 can also be directly detachably connected to the output end of the telescopic drive device 80, specifically, a threaded connection can be adopted for easy disassembly and assembly; according to the needs of detection, the third detection rod 60 can be used or not. During the detection process, if the operator finds that the detection depth of the first detection rod 10 is insufficient, the first detection rod 10 can be disassembled from the output end of the telescopic drive device 80, and then the output end of the telescopic drive device 80 can be retracted upward, and the third detection rod 60 can be installed on the upper end of the first detection rod 10, and then the upper end of the third detection rod 60 can be connected to the output end of the telescopic drive device 80. Figure 5 As shown, the telescopic driving device 80 is finally started, and the output end of the telescopic driving device 80 slowly extends downward, driving the first detection rod 10 to continue to detect downward.

[0050] Please refer to Figure 4 and Figure 5 The tripod assembly 90 includes a telescopic sleeve 91 detachably connected to the chassis 70, a telescopic rod 92 that is telescopically matched with the telescopic sleeve 91, and a bolt locking member 93 provided on the telescopic sleeve 91 and used to lock the telescopic rod 92. The bottom of the telescopic rod 92 is a conical structure, which is convenient for the lower end of the telescopic rod 92 to be inserted into the embankment 100. A groove 94 is provided on the outer side of the lower end of the telescopic rod 92. The concave-convex structure increases the friction coefficient and prevents the telescopic rod 92 from loosening. The tripod assembly 90 is designed to be a telescopic structure. Before detection, the lower end of the telescopic rod 92 is first inserted into the soil 100, and then detection is carried out; during detection, if the operator finds that the detection depth of the detection rod 10 is insufficient, the detection rod 10 can be disassembled from the output end of the telescopic drive device 80, and then the output end of the telescopic drive device 80 can be retracted upward, and then the telescopic rod 92 can be pulled out of the telescopic sleeve 91. After the telescopic rod 92 is locked by the bolt locking member 93, the third detection rod 60 is added to the upper end of the detection rod 10 to reduce the difficulty of installation of the detection rod 10.

[0051] Furthermore, an alarm 74 is provided on the chassis 70, and the alarm 74 is communicated with the control panel 71. When the pressure sensor 31 senses a pressure change, the signal can be fed back to the control panel 71 through the pressure sensor 31, and the control panel 71 then controls the alarm 74 to sound an alarm to remind the operator.

[0052] Please refer to Figure 6 A handle 72 is provided on any side of the chassis 70, and a storage cavity 73 is also provided inside the chassis 70. A retractable cover 75 is provided on one side of the storage cavity 73. After the detection is completed, the cover 75 can be opened and the first detection rod 10, the third detection rod 60, and the tripod assembly 90 can be stored in the storage cavity 73 for easy carrying.
