Referring to fig. 1-5, fig. 1-5 show a specific structure of a penetration probe 30 provided in an embodiment, the penetration probe 30 is driven to move a penetration probe 32 relative to a penetration surface under water for performing a penetration test.
As can be seen from fig. 1 to 5, the penetration probe 30 includes a main frame 31, a penetration probe 32, a drill rod receiving mechanism 33, a drill rod penetration mechanism 34 and a drill rod displacement measuring mechanism;
the drill rod storage mechanism 33, the drill rod penetration mechanism 34 and the drill rod displacement measuring mechanism are all connected with the main frame body 31;
one end of the sounding rod 32 is connected with a drill rod receiving mechanism 33, so that the drill rod receiving mechanism 33 can be used for receiving the sounding rod 32; the other end of the sounding probe rod 32 is provided with a sounding probe;
the drill rod penetration mechanism 34 is in transmission connection with the sounding probe 32 and is used for driving the sounding probe 32 to move along a preset direction so as to drive the sounding probe to penetrate into a sounding surface or drive the drill rod to move and store the drill rod into the drill rod storage mechanism 33;
the drill rod displacement measuring mechanism is connected to the transmission and moves synchronously with the drill rod penetration mechanism 34 to measure the displacement of the sounding rod 32 in a preset direction by the drill rod displacement measuring mechanism.
In the process of underwater static sounding, the drill rod penetration mechanism 34 can drive the sounding rod 32 to move in a preset direction, and in the process of movement of the sounding rod 32, the drill rod penetration mechanism 34 can control the movement direction of the sounding rod to drive the sounding rod 32 to move towards the sounding surface and penetrate into the sounding surface so as to complete the underwater static sounding test; or drive the component feeler lever to move in the other direction, so as to drive the drill rod of the component feeler lever 32 to move and be accommodated in the drill rod accommodating mechanism 33. Thereby can accomplish the penetration measurement or the accomodating of touch pole through drilling rod penetration mechanism 34 to can effectively simplify the operation that detects, and can effectively improve the efficiency that detects. In addition, in the foregoing process, the drill pipe displacement measuring mechanism may measure the movement of the drill pipe penetration mechanism 34 to detect the movement of the sounding rod 32 under the action of the drill pipe penetration mechanism 34 under water, so as to measure the movement of the sounding rod 32, and control the movement of the sounding rod 32 according to the measured structure. Therefore, when the penetration device 30 is applied to an underwater static sounding test, the penetration device is simple in structure and convenient to operate, and the penetration motion of the penetration probe 32 can be accurately controlled through the matching work of the drill rod penetration mechanism 34 and the drill rod displacement measuring mechanism, so that the stability of the motion of the penetration probe 32 is ensured, and the test precision is improved; secondly, can also improve the efficiency of quiet power penetration test under water.
It should be noted that the penetration device 30 may further include a control system, and the control system is electrically connected to the drill rod displacement measuring mechanism, the penetration probe 32, the drill rod receiving mechanism 33 and the drill rod penetration mechanism 34 to collect measurement signals output by the penetration probe and measured by the drill rod displacement measuring mechanism, and controls the movement of the penetration probe 32 through the drill rod receiving mechanism 33 and the drill rod penetration mechanism 34.
Specifically, in this embodiment, the penetration device 30 is configured with a sounding machine underwater PLC controller and a surface computer, and the sounding machine underwater PLC controller and the surface computer can realize automatic data exchange. It should be noted that the selection of the underwater PLC controller of the sounding device and the water surface computer can be selected according to the actual environment, and the underwater PLC controller of the sounding device and the water surface computer are in the prior art, and therefore are not described herein again.
Therefore, when the control system is arranged, the penetration device 30 can be controlled and operated on the water surface by a computer, so that the drill rods are automatically connected to form the penetration rod 32, and the penetration rod is automatically loaded to complete all penetration work. Data acquired by a penetration probe in a penetration site is exchanged and stored with a water surface computer in real time; in addition, during the operation, the penetration probe 30 may be automatically operated by operating a pre-programmed program, and the penetration probe 32 may be automatically pulled up and pulled out. Therefore, the operator can complete the penetration work of the sounding probe rod 32 only by monitoring the computer on the water surface.
Referring to fig. 1, in the present embodiment, during the underwater static sounding test, a sounding rod 32 needs to penetrate into a sounding surface to complete the test. Therefore, when the sounding probe 32 is arranged, the length of the sounding probe 32 needs to be greater than the sounding depth, and in this embodiment, the sounding probe 32 is formed by sequentially connecting a plurality of drill rods, so that when the sounding probe 32 is arranged, adjacent drill rods can be hinged to each other so as to be conveniently retracted and extended, and the plurality of drill rods are provided with guide cylinders which are slidably connected with the drill rods so that the guide cylinders are provided with first positions which are located at the hinged positions of the adjacent drill rods and limit the movement between the adjacent drill rods; and a second position away from the articulation of the adjacent drill rod. The drill rod further comprises a positioning steel ball, and the positioning steel ball is used for being matched with the guide cylinder so as to limit the sliding of the guide cylinder on the drill rod.
Thereby make two adjacent drilling rods can be when the primary importance, the guide cylinder possesses the articulated department that is in adjacent drilling rod, and with two adjacent drilling rod cooperations, thereby make the axis coincidence of two adjacent drilling rods, and play the condition emergence of the axis skew of two adjacent drilling rods of restriction, thereby make the drilling rod after forming sounding probe 32, can be through the limiting displacement of guide cylinder, the axis that keeps a plurality of drilling rods coincides each other, thereby make sounding probe 32's penetration direction can obtain effective control, so that the precision of improvement test. In addition, when two adjacent drill rods are in the second position, the limiting effect of the guide cylinder disappears, so that the two adjacent drill rods can rotate around the hinged joint of the two adjacent drill rods, and the two adjacent drill rods can be stored.
Referring to fig. 5, in order to store and release the drill rod, the drill rod storage mechanism 33 includes a guiding and positioning winch 331 and a six-sided winch 332, and both the guiding and positioning winch 331 and the six-sided winch 332 have side surfaces adapted to the rod body of the drill rod; the guiding and positioning winch 331 and the six-sided winch 332 are rotatably connected with the main frame 31; the six-sided winch 332 is used for accommodating the sounding rod 32, and the guiding and positioning winch 331 is used for guiding the sounding rod 32 to move from the drill rod penetration mechanism 34 to the six-sided winch 332, or guiding the sounding rod 32 to move from the six-sided winch 332 to the drill rod penetration mechanism 34. The six-sided winch 332 is rotatably connected to the main frame 31 via a transmission shaft 333, so that the six-sided winch 332 is driven to move and rotate relative to the main frame 31 via the transmission shaft 333.
Specifically, in the present embodiment, the six-sided winch 332 of the boring bar storage mechanism 33 is a one-way driving mechanism, and when the main cylinder 344 drives the sounding rod 32 to move, the six-sided winch 332 rotates to pay out the boring bar stored in the six-sided winch 332 following the extension of the sounding rod 32. The transmission shaft 333 at the center of the six-sided winch 332 is a spiral shaft, one end of the transmission shaft 333 is in transmission connection with the transmission device of the main frame body 31, and the other end of the transmission shaft 333 is in threaded connection with the main frame body 31, so that when the transmission device drives the transmission shaft 333 to rotate, the transmission shaft 333 is driven to move along the central axis direction thereof. So that the transmission shaft 333 can rotate the six-sided capstan 332 along the central axis of the transmission shaft 333 and move in parallel, so as to receive the drill rod on the six-sided capstan 332. Therefore, the transmission shaft 333 horizontally advances by the diameter of the sounding probe 32 every revolution, so that the drill rod is not twisted or transversely deflected when being released, and the damage to the drill rod and a special waterproof cable is eliminated; the drill rods can be arranged in sequence when being wound on the six-sided capstan 332 for recycling.
When the drill rod is recovered, the six-side winch 332 is driven to rotate by a hydraulic motor on the six-side winch 332 mechanism, and at the moment, the drill rod penetration mechanism 34 works in the reverse direction according to the loading sequence. That is, when the master cylinder 344 extends upwards, the piston of the locking loading cylinder 343 remains locked, the rod-changing clamping cylinder 345 is in a released state (the feeler lever 32 can move), the feeler lever 32 is pulled out as the master cylinder 344 rises, and the six-sided winch 332 mechanism rotates at a speed regulated by the automatic control system, receives drill rods and sequentially winds and arranges the drill rods on the six-sided winch 332.
Referring to fig. 1 and 2, in addition, during the penetration of the sounding rod 32 and the receiving rod, the sounding rod 32 needs to be driven to move by the drill rod penetration mechanism 34. Therefore, when the drill rod penetration mechanism 34 is provided, it may include a loading beam 341, a rubber sleeve 342, a locking loading cylinder 343, a main cylinder 344, a rod changing clamping cylinder 345, and a lower beam 346 of the lower beam 346.
The main oil cylinder 344 is arranged along the gravity direction, two ends of the main oil cylinder 344 are respectively connected with the loading cross beam 341 and the lower cross beam 346 of the lower cross beam 346, and the magnetic ring connecting piece 355 is connected with a piston rod of the main oil cylinder 344; a locking loading oil cylinder 343 and a rubber sleeve 342 are connected with the loading cross beam 341, and a rod changing clamping oil cylinder 345 is connected with a lower cross beam 346 of the lower cross beam 346; the sounding rod 32 sequentially passes through the loading beam 341 and the lower beam 346 of the lower beam 346 along the gravity direction, and is matched with the rubber sleeve 342, the locking loading cylinder 343 and the rod-changing clamping cylinder 345, so that the sounding rod 32 and the magnetic ring 354 are driven to move along the gravity direction through the main cylinder 344. The locking loading cylinder 343 and the rod-changing clamping cylinder 345 each include a locking block for engaging with the feeler lever 32, and a cylinder for driving the locking block to move.
Specifically, the penetration probe 32 passes through the center of the loading beam 341, firstly passes through the rubber sleeve 342, secondly enters the penetration probe 32 to lock the loading cylinder 343, and before working, the positions of the clamping groove and the locking block on the penetration probe 32 need to be adjusted, and the locking block can slide left and right in the clamping groove of the penetration probe 32.
In the process that the main cylinder 344 drives the sounding rod 32 to move along the gravity direction, the main cylinder 344 drives the sounding rod 32 to move along the gravity direction through the matching effect of locking blocks on both the locking loading cylinder 343 and the rod changing clamping cylinder 345 and the connecting effect of the magnetic ring connecting piece 355 connecting the magnetic ring 354 and the main cylinder 344, and the magnetic sensor 352 measures the movement amount of the sounding rod 32 in the process that the magnetic ring 354 synchronously moves, so that the effect of detecting the movement of the sounding rod 32 is achieved.
In summary, referring to fig. 1 to 5, when the penetration of the sounding rod 32 is performed by the sounding rod penetration device 30, in the present embodiment, the six-sided winch 332 is used to store at least 30 meters of sounding rod 32 for sounding. The drill rods are connected in a hinged mode, and the relative position of the sounding rod 32 and a loading cross beam 341 of the sounding machine is determined by a guide positioning winch 331. The slidable guide tube on the feeler lever 32 can move up and down for locking or releasing the feeler lever 32 so that the levers can be bent or not. The main cylinder 344 of the loading system during penetration makes the penetration probe 32 move downwards and drives the six-face winch 332 to rotate to release the penetration probe 32, and when the penetration probe 32 passes through the rubber sleeve 342 at the center of the penetration loading upper cross beam, the friction resistance makes the guide cylinder move upwards to the positioning stop of the penetration probe 32 and stop. The guide cylinder will not slide down due to the positioning steel ball on the sounding rod 32. Since the guide sleeve is inserted between the joints of the two feeler levers 32, the feeler levers 32 cannot be bent at this time. After the penetration is finished, the action sequence is opposite to that during penetration, the penetration loading upper cross beam is enabled to move upwards by using the locking loading oil cylinder 343, the penetration probe rod 32 is pulled out, when the guide cylinder of the penetration probe rod 32 passes through the rubber sleeve 342, the penetration probe rod slides downwards due to friction resistance, and the joint between the two drill rods can be bent at the moment; meanwhile, a hydraulic motor arranged at the end of the six-face winch 332 rotates a central lead screw under the control of an electro-hydraulic proportional servo valve to drive the six-face winch 332 to rotate and withdraw the sounding rod 32. When the lead screw rotates, the six-face capstan 332 can transversely and horizontally move along with the thread of the lead screw besides rotating, so that the sounding probe rod 32 is automatically and orderly wound and arranged on the capstan. The underwater penetration sounding machine and the water surface computer can realize automatic data exchange, and the penetration sounding machine controls a hydraulic system through an underwater PLC (programmable logic controller) according to a pre-programmed program to enable a penetration sounding cylinder to complete automatic loading control circulation, so that the penetration sounding rod 32 is repeatedly pressed in a loading system; after the penetration is finished, the operation is reversed according to the water surface operation command, all penetration probe rods 32 are withdrawn, and the six-sided winch 332 is automatically wound. The operation can be intervened manually by a computer in the working process.
Referring to fig. 4 and 5, in order to detect the displacement of the penetration probe 32 during the penetration process of the penetration probe 32, the displacement measuring mechanism of the drill rod includes a sealed cavity 351, a magnetic sensor 352, a measuring rod 353, a magnetic ring 354 and a magnetic ring connector 355. The sealed cavity 351 is a closed cavity, and the magnetic sensor 352 is disposed in the sealed cavity 351, so that the magnetic sensor 352 is ensured to be in a waterproof working environment through the sealed cavity 351. One end of the measuring rod 353 extends into the sealed cavity 351 and is connected with the magnetic sensor 352, and the other end of the measuring rod 353 is positioned outside the sealed cavity 351. The magnetic ring 354 is slidably engaged with the measuring rod 353 and is connected to the piston rod of the main cylinder 344 of the rod penetration mechanism 34 through the magnetic ring connector 355, so that the feeler lever 32 and the magnetic ring 354 are driven by the main cylinder 344 to move in the gravity direction, so that the magnetic ring 354 moves synchronously with the rod penetration mechanism 34 relative to the measuring rod 353.
It should be noted that, for measuring the displacement, one end of the measuring rod 353 needs to be connected to the magnetic sensor 352 disposed in the sealed cavity 351, while the other end of the measuring rod 353 extends out of the sealed cavity 351, and the magnetic ring 354 for measuring can slide relative to the measuring rod 353 so as to facilitate the measurement. In addition, in order to measure a target measurement object, the magnetic ring 354 and the measurement piece need to move synchronously, and therefore, the magnetic ring is connected with the drill rod penetration mechanism 34 through the magnetic ring connecting piece 355, so that the magnetic ring 354 and the drill rod penetration mechanism 34 move synchronously relative to the measurement rod 353, the movement of the drill rod penetration mechanism 34 is measured through the magnetic sensor 352, the movement of the drill rod driven by the drill rod penetration mechanism 34 is detected, the movement of the drill rod is measured conveniently, and the movement of the drill rod is controlled according to the measured structure.
Further, in this embodiment, in order to improve the waterproof performance of the drill rod displacement measuring mechanism, so as to ensure the use stability of the drill rod displacement measuring mechanism in the working process, and improve the use performance and the service life of the drill rod displacement measuring mechanism under water, when the seal cavity 351, the magnetic sensor 352 and the measuring rod 353 are provided, and when the seal cavity 351 and the measuring rod 353 are assembled, the connection or detachable parts are respectively provided with a sealing ring and other structures for sealing, so as to improve the overall sealing and waterproof performance of the seal cavity 351. Therefore, the working performance of the drill rod displacement measuring mechanism when the drill rod displacement measuring mechanism is applied to underwater measurement is ensured.

In addition, the first fixing frame 356 is disposed on the sealed cavity 351 and is located at one end of the measuring rod 353 extending out of the sealed cavity 351; and a second mount 357 is provided at an end of the measuring rod 353 remote from the sealed housing 351.
Further, during the operation of the drill rod displacement measuring mechanism, the displacement signal collected by the magnetic sensor 352 can be transmitted to an external controller through a cable, so that the cable can extend into the sealed cavity 351 and be electrically connected with the magnetic sensor 352 in the sealed cavity 351, and the sealed cavity 351 further comprises an opening and a sealing cover 358 for closing the opening.
