[0023] Embodiments

[0024] Please refer to Figures 1-3 , Figure 1 A structural schematic diagram of a stack water nondestructive membrane probe machine provided by the embodiments of the present application; Figure 2 A connection schematic diagram of a valve assembly of a stack water nondestructive membrane probe machine provided by the embodiments of the present application; Figure 3 A structural schematic diagram of a membrane probe drill bit of a stack water nondestructive membrane probe machine provided by the embodiments of the present application.

[0025] The embodiments provide a stack water nondestructive membrane probe machine, which can include a control mechanism, an execution mechanism and a drilling assembly. The control mechanism can include a drilling machine assembly and a water pumping mechanism. The drilling machine assembly can include a rack 1, a drilling machine 2 and a slide rail 3. The drilling machine 2 is arranged on the rack 1, and the slide rail 3 is arranged at one end of the rack 1. The water pumping mechanism can include a water pipe 4 and a mud pump 5. The mud pump 5 is arranged on the rack 1.

[0026] The execution mechanism can include an electric contact pressure gauge 6, a feeding power head 7 and a valve assembly. The feeding power head 7 is slidably arranged on the slide rail 3. The electric contact pressure gauge 6 is arranged at the middle part of the water pipe 4. The valve assembly is arranged on the slide rail 3 and is electrically connected with the electric contact pressure gauge 6. The feeding power head 7 is connected with the drilling machine 2 through the valve assembly.

[0027] The drilling assembly can include a drill pipe 8 and a membrane-probing drill bit 9, one end of the drill pipe 8 is communicated with the water outlet end of the mud pump 5 through the water pipe 4, one end of the drill pipe 8 is connected with the feeding power head 7, the membrane-probing drill bit 9 is arranged at the other end of the drill pipe 8, the membrane-probing drill bit 9 can include a probe rod 91, a valve body 92 and a return elastic member 93, the probe rod 91 and the return elastic member 93 are arranged in the interior of the valve body 92, one end of the probe rod 91 is connected with one end of the return elastic member 93, the other end of the probe rod 91 is a free end, a water passing hole 94 is arranged in the middle section of the probe rod 91, a plurality of water outlet holes 95 are arranged at the end of the valve body 92 away from the drill pipe 8.

[0028] It should be noted that when the membrane-probing operation is needed, the drilling machine 2 is started to control the valve assembly. The drilling machine 2 is started at the same time, and the mud pump 5 is started, the water pumped out of the mud pump 5 is delivered to the drill pipe 8 through the water pipe 4, the water is sprayed into the membrane-probing drill bit 9 at a certain pressure, and the tailings sand 17 is impacted through the water outlet holes 95 on the membrane-probing drill bit 9, so that the probe rod 91 of the membrane-probing drill bit 9 can normally descend.

[0029] The feeding power head 7 moves to the ground on the slide rail 3 under the control of the valve assembly, the membrane-probing drill bit 9 installed on the drill pipe 8 automatically follows under the driving of the drill pipe 8, and drills underground. When the probe rod 91 does not detect the waterproof membrane 18 in the moving process, the water flow can normally flow through the water passing hole 94 and is sprayed out of the water outlet hole 95 at a certain pressure. When the membrane-probing drill bit 9 touches the waterproof membrane 18, the probe rod 91 encounters resistance, extrudes the return elastic member 93, and the water passing hole 94 on the probe rod 91 is blocked by the valve body 92, so that the water pressure in the valve body 92 increases, thereby causing the water pressure in the water pipe 4 to rise synchronously, when the water pressure reaches a set value, the pressure value is detected by the electric contact pressure gauge 6, and a signal is transmitted to the drilling machine 2, the drilling machine 2 controls the valve mechanism to make the feeding power head 7 stop moving downward, so as to accurately determine the position of the underground waterproof membrane 18.

[0030] In the embodiment, the membrane-probing drill bit 9 and the drill pipe 8 are connected by threads, which is convenient for disassembly.

[0031] In the embodiment, the valve body 92 is further provided with a valve cover 96 and a sleeve 97 for installing the return elastic member 93 at two ends thereof, the sleeve 97 is installed on the valve body 92 at the end connected with the drill pipe 8, and the water outlet holes 95 are distributed on the valve cover 96. The valve cover 96 and the sleeve 97 are detachably connected with the valve body 92, which is convenient for disassembly and replacement when maintenance or replacement of parts is needed.

[0032] In the embodiment, the rack 1 is further provided with a traveling mechanism 10 away from the drilling machine 2, and the traveling mechanism 10 is a track driving mechanism.

[0033] It can be understood that the walking mechanism 10 facilitates the movement of the membrane exploration machine. The working environment of the membrane exploration machine is often uneven outdoor ground, and the soil is soft or muddy. The track driving mechanism has the advantages of large supporting area, small ground pressure, small sinking degree, small rolling resistance, good cross-country mobility, ability to walk on uneven ground, ability to cross obstacles, ability to climb small steps, and superior performance in climbing and crossing ditches. The track supporting surface has a track tooth, so it is not easy to slip, has good traction adhesion, and is conducive to exerting greater traction force. Therefore, the track driving mechanism can well adapt to the working environment of the membrane exploration machine.

[0034] In this embodiment, the valve assembly includes a feeding power head lifting cylinder 11 and a lifting control valve 12. One end of the feeding power head lifting cylinder 11 is connected with the feeding power head 7, and the other end of the feeding power head lifting cylinder 11 is communicated with the lifting control valve 12 through an oil pipe. The lifting control valve 12 is connected with the drilling machine 2.

[0035] It should be noted that after the drilling machine 2 is started, the feeding power head lifting cylinder 11 moves the feeding power head 7 on the slide rail 3 under the control of the lifting control valve 12.

[0036] The hydraulic drive mode has the advantages of various elements of hydraulic transmission, convenient and flexible arrangement according to needs, light weight, small volume, small motion inertia, fast response speed, convenient operation and control, realization of large-range stepless speed regulation, automatic overload protection, use of mineral oil as working medium, self-lubrication of relative motion surfaces, long service life, easy realization of linear motion, and easy realization of machine automation. When electric-hydraulic combined control is adopted, not only a higher degree of automatic control process can be realized, but also remote control can be realized. Therefore, in this embodiment, the driving mode of the drilling machine 2 is hydraulic drive, so as to better adapt to the working environment of the membrane exploration machine.

[0037] In this embodiment, a balance valve 13 is further arranged between the feeding power head lifting cylinder 11 and the lifting control valve 12.

[0038] It should be noted that the balance valve 13 can prevent the feeding power head lifting cylinder 11 from losing control due to excessive load, prevent the membrane drill bit 9 from continuing to descend and penetrate the waterproof membrane 18, and thus prevent water from flowing into the tailings pond bottom 19.

[0039] In this embodiment, an electromagnetic reversing valve 14 is further arranged between the balance valve 13 and the lifting control valve 12.

[0040] It should be noted that the electromagnetic reversing valve 14 is used to control the direction and on-off of the liquid flow in the hydraulic system.

[0041] In this embodiment, the water pumping mechanism can further include a water tank 16. The water inlet end of the mud pump 5 is communicated with the water tank 16 through the water pipe 4.

[0042] It should be noted that the water tank 16 is external, and the water tank 16 can move with the movement of the membrane detector. The device is supplied with water through the external water tank 16, which can reduce the floor area of the membrane detector and simplify the structure.

[0043] In the embodiment, the battery 15 is arranged on the rack 1, and the electric contact pressure gauge 6 and the electromagnetic reversing valve 14 are electrically connected with the battery 15.

[0044] It should be noted that the battery 15 is responsible for providing electricity to the electric contact pressure gauge 6 and the electromagnetic reversing valve 14.

[0045] To sum up, the embodiment of the present application provides a stack water nondestructive membrane detector. High-pressure water flow is punched into the drill rod 8 through the water pipe 4 by the mud pump 5, and finally the reaming is performed through the high-pressure jet of the membrane detector drill bit 9. The drill rod 8 automatically follows under the control of the drilling machine 2. When the membrane detector drill bit 9 on the drill rod 8 touches the waterproof membrane 18, the water flow channel on the membrane detector drill bit 9 is blocked, resulting in the increase of water pressure in the water pipe 4. The pressure signal is transmitted to the drilling machine 2 through the electric contact pressure gauge 6, and the drilling machine 2 controls the automatic stop of the feed power head 7 to follow, so as to accurately determine the position of the underground waterproof membrane 18 and reduce the risk of drilling leakage of the waterproof membrane 18 in the process of vertical shaft construction.

[0046] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes.
