Description

Technical Field

[0001] The invention relates to the technical field of magnetic exploration equipment, in particular to a magnetic exploration equipment with a protective structure. Background Art

[0002] Magnetic exploration equipment is an instrument used to measure magnetic field strength and magnetic parameters in magnetic exploration. There are many types of magnetic exploration equipment. According to different measurement purposes, it can be divided into two categories: magnetometers for measuring magnetic field strength and magnetometers for measuring rock magnetic parameters.

[0003] According to a disclosed magnetometer probe rod device and magnetometer (announcement number: CN217305010U), a multi-section connected probe rod body is adopted in the above application, and the multi-section connected probe rod body is a retractable structure, and adjacent probe rod bodies are connected by elastic components. When in use, the probe rod bodies can be extended one by one, meeting the length requirement of the magnetic probe rod. When carried, the probe rod body can be retracted to the length of one probe rod body, which has the advantages of being easy to carry and requiring no assembly and disassembly.

[0004] However, in actual use of the above-mentioned equipment, when the detection rod is inserted into the ground, it is difficult to prevent the detection rod from tipping over by relying solely on the friction of the ground. When encountering softer ground, the softer ground may not produce enough friction with the detection rod to make the detection rod upright, which causes the detection rod to easily tip over, reducing the detection efficiency of the detection rod. In view of this, we propose a magnetic exploration equipment with a protective structure. Summary of the invention

[0005] The object of the present invention is to provide a magnetic exploration device with a protective structure to solve the problems raised in the above background technology.

[0011] Preferably, the slide rod passes through the slider, the slider is slidably connected to the outer wall of the slide rod, the slider is hinged to the tooth plate, the inner wall of the support frame is provided with a push-out groove, the limit plate is slidably connected to the inner wall of the push-out groove, when the telescopic threaded cylinder descends and drives the ring to descend, the ring pulls the hinge plate to rotate, so that the hinge plate drives the support frame to rotate, and at this time the active gear drives the tooth plate to move through the driven gear, so that the tooth plate pushes the pressure plate to rotate, so that when the support frame rotates, the pressure plate always remains flush with the ground.

[0012] Preferably, the detection rod passes through the sleeve and the telescopic threaded cylinder at the same time, and the detection rod is rotatably connected to the sleeve and the telescopic threaded cylinder. The outer wall of the detection rod is provided with a block, and the inner wall of the sleeve is provided with an annular groove matching the block. The block is slidably connected to the inner wall of the groove, so that the telescopic threaded cylinder can be extended and retracted while the sleeve rotates. At this time, the detection rod moves with the telescopic threaded cylinder, so that the detection rod can be smoothly inserted into the soil, preventing the drill bit from violently contacting hard objects due to manual insertion.

[0013] Preferably, the arc surface of the arc block is arranged at one end close to the roller, and the lower ends of the roller and the arc block are flush with the outer wall of the lower end of the pressure plate. When the telescopic threaded cylinder descends, the ring drives the hinged plate to push the support frame to rotate, so that when the pressure plate slides on the ground, the pressure plate can slide better on the ground through the pulley. The arc block enables the pressure plate to move better when it moves away from the detection rod, and when it moves toward the detection rod, it is subjected to greater friction and is difficult to move.

[0014] Preferably, one end of the support frame away from the fixed plate is hinged to the end of the hinge plate away from the collar, the driven gear is rotatably connected to the inner wall of the support frame, and the tooth plate is meshed with the driven gear, so that the rotation of the hinge plate can drive the driving gear to rotate, thereby causing the driving gear to drive the driven gear to rotate, causing the driven gear to drive the tooth plate to move, so that the pressure plate rotates around the end of the support frame close to the drill bit.

[0015] Preferably, the limit block is slidably connected to the inner wall of the limit groove, and the ring is arranged on the outer wall of the telescopic threaded cylinder located at the lower end of the fixed plate, so that when the output end of the telescopic threaded cylinder rotates and descends, the ring will only descend as the telescopic threaded cylinder descends, and will not rotate with the telescopic threaded cylinder, so that the anti-reversal assembly remains stable.

[0016] Preferably, there are three groups of support frames and hinged plates, which are respectively distributed in a circular array on the outer walls of the fixed disk and the ring, so that the fixed disk is supported in three directions, so that the anti-reverse component has a better supporting effect. At the same time, the rolling directions of the rollers arranged under the three groups of support frames are inconsistent, so that the pressure plate can only move in the direction of the rolling of the rollers, and the position of the detection rod is not easy to change during insertion.

[0017] Preferably, the area of ​​the pressing plate is consistent with the cross-sectional area of ​​the support frame, and the pressing plate fits the outer wall of the lower end of the support frame, so that when the detection rod is not inserted, the pressing plate remains flush with the ground.

The connecting sleeve is fixedly connected to the fixed disk via the connecting plate, and the transmission line passes through the connecting sleeve and is electrically connected to the detection rod, so that when the motor drives the sleeve to drive the telescopic threaded barrel to rotate, the telescopic threaded barrel is connected to the fixed disk through a thread so that when the telescopic threaded barrel rotates, the telescopic end of the telescopic threaded barrel is extended.

[0019] Preferably, the lower end of the drill bit is flush with the pressure plate, and the telescopic threaded barrel is threadedly connected to the axis of the fixed plate, and the detection rod passes through the axis of the telescopic threaded barrel, so that when the detection rod is pressed down, the support frame rotates through the ring and the hinge plate, so that the detection rod can be inserted a deeper distance.

[0020] Compared with the prior art, the present invention provides a magnetic exploration device with a protective structure, which has the following beneficial effects:

[0021] 1. The magnetic exploration equipment with a protective structure has a ring that drops when the detection rod is pressed down. At this time, the ring pulls the hinged plate to rotate, so that the hinged plate drives the support frame to rotate. At this time, the active gear rotates with the hinged plate, so that the driven gear meshing with it drives the toothed plate to move, so that the toothed plate pushes the pressure plate to rotate, so that when the support frame rotates, the pressure plate always remains flush with the ground, so that the friction between the pressure plate and the ground is greater, so that the detection rod is less likely to fall over.

[0022] 2. In the magnetic exploration equipment with a protective structure, when the motor drives the sleeve to drive the telescopic threaded barrel to rotate, the telescopic threaded barrel is connected to the fixed plate through a thread so that when the telescopic threaded barrel rotates, the telescopic end of the telescopic threaded barrel is extended. At this time, the detection rod moves with the telescopic end of the telescopic threaded barrel, so that the detection rod is smoothly inserted into the soil, preventing the drill bit from violently contacting with hard objects due to manual insertion, causing damage to the drill bit, and reducing the use effect of the detection rod.

[0023] 3. The magnetic exploration equipment with a protective structure is capable of better sliding of the pressure plate on the ground through the pulley, and the arc block enables the pressure plate to better move when it moves away from the detection rod, and when it moves toward the detection rod, it is subjected to greater friction and is difficult to move, thereby preventing the support frame from being hit and causing the detection rod to be pulled out.

[0035] In one embodiment of the present invention, the limiting groove 125 is opened on the outer wall of the telescopic threaded tube 9, the outer wall of the ring 123 is hinged with a hinge plate 126, the lower end of the hinge plate 126 is fixedly connected with a driving gear 127, and the outer wall of the driving gear 127 is hinged with a driven gear 128.

[0036] In one embodiment of the present invention, the tooth plate 129 is slidably connected to the inner wall of the support frame 122, the outer wall of the tooth plate 129 is fixedly connected to the limiting plate 1210, the lower end of the support frame 122 is rotatably connected to the pressure plate 1211, and the outer wall of the pressure plate 1211 is provided with a sliding groove 1212.

[0038] In addition, the slide bar 1214 passes through the slider 1213, the slider 1213 is slidably connected to the outer wall of the slide bar 1214, the slider 1213 is hinged to the tooth plate 129, the inner wall of the support frame 122 is provided with a push-out groove, and the limit plate 1210 is slidably connected to the inner wall of the push-out groove. When the telescopic threaded tube 9 descends and drives the ring 123 to descend, the ring 123 pulls the hinge plate 126 to rotate, so that the hinge plate 126 drives the support frame 122 to rotate. At this time, the active gear 127 drives the tooth plate 129 to move through the driven gear 128, so that the tooth plate 129 pushes the pressure plate 1211 to rotate, so that when the support frame 122 rotates, the pressure plate 1211 always remains flush with the ground, so that the friction between the pressure plate 1211 and the ground is greater, thereby making the detection rod 10 less likely to tip over.

[0039] In an embodiment of the present invention, the detection rod 10 passes through the sleeve 8 and the telescopic threaded tube 9 at the same time, and the detection rod 10 is rotatably connected with the sleeve 8 and the telescopic threaded tube 9. A clamping block is provided on the outer wall of the detection rod 10, and an annular clamping groove matching the clamping block is provided on the inner wall of the sleeve 8. The clamping block is slidably connected with the inner wall of the clamping groove, so that the telescopic threaded tube 9 can be extended and retracted while rotating with the sleeve 8. At this time, the detection rod 10 moves with the telescopic threaded tube 9, so that the detection rod 10 can be smoothly inserted into the soil, preventing manual insertion from causing the drill bit 11 to contact violently with hard objects, causing damage to the drill bit 11, and reducing the use effect of the detection rod 10.

[0040] In an embodiment of the present invention, the arc surface of the arc block 1216 is arranged at one end close to the roller 1215, and the lower ends of the roller 1215 and the arc block 1216 are flush with the outer wall of the lower end of the pressure plate 1211. When the telescopic threaded tube 9 descends, the ring 123 drives the hinged plate 126 to push the support frame 122 to rotate, so that when the pressure plate 1211 slides on the ground, the pressure plate 1211 can slide better on the ground through the pulley. The arc block 1216 enables the pressure plate 1211 to move better when it moves away from the detection rod 10. When it moves toward the direction close to the detection rod 10, it is subjected to greater friction and is difficult to move, thereby preventing the support frame 122 from being hit and causing the detection rod 10 to be pulled out.

[0041] In an embodiment of the present invention, one end of the support frame 122 away from the fixed disk 121 is hinged to the end of the hinged plate 126 away from the collar 123, the driven gear 128 is rotatably connected to the inner wall of the support frame 122, and the toothed plate 129 is meshed with the driven gear 128, so that the rotation of the hinged plate 126 can drive the driving gear 127 to rotate, thereby causing the driving gear 127 to drive the driven gear 128 to rotate, causing the driven gear 128 to drive the toothed plate 129 to move, so that the pressure plate 1211 rotates around the end of the support frame 122 close to the drill bit 11, so that the pressure plate 1211 always remains flush with the ground.

[0042] In an embodiment of the present invention, the limit block 124 is slidably connected to the inner wall of the limit groove 125, and the ring 123 is arranged on the outer wall of the telescopic threaded tube 9 located at the lower end of the fixed plate 121, so that when the output end of the telescopic threaded tube 9 rotates and descends, the ring 123 will only descend with the telescopic threaded tube 9 and will not rotate with the telescopic threaded tube 9, thereby preventing the anti-reversal component 12 from rotating and making the anti-reversal component 12 more stable.

[0043] In an embodiment of the present invention, there are three groups of support frames 122 and hinged plates 126, and the three groups of support frames 122 and hinged plates 126 are respectively distributed in a circular array on the outer walls of the fixed disk 121 and the ring 123, so that the fixed disk 121 is supported in three directions, so that the anti-reverse component 12 has a better supporting effect. At the same time, the rolling directions of the rollers 1215 arranged under the three groups of support frames 122 are inconsistent, so that the pressure plate 1211 can only move in the direction of the rolling of the rollers 1215, so that the position of the detection rod 10 is not easy to change during insertion, thereby making the anti-reverse component 12 more stable.

[0044] In an embodiment of the present invention, the area of ​​the pressure plate 1211 is consistent with the cross-sectional area of ​​the support frame 122, and the pressure plate 1211 fits the outer wall of the lower end of the support frame 122, so that when the detection rod 10 is not inserted, the pressure plate 1211 remains flush with the ground, so that the detection rod 10 can remain stable at this time.

[0045] In an embodiment of the present invention, a motor is arranged inside the connecting sleeve 7, and the output end of the motor is fixedly connected to the outer wall of the upper end of the sleeve 8. The outer wall of the connecting sleeve 7 is fixedly connected to a connecting plate. The connecting sleeve 7 is fixedly connected to the fixed disk 121 through the connecting plate. The transmission line 6 passes through the connecting sleeve 7 and is electrically connected to the detection rod 10. When the motor drives the sleeve 8 to drive the telescopic threaded cylinder 9 to rotate, the telescopic threaded cylinder 9 is connected to the fixed disk 121 through a thread so that when the telescopic threaded cylinder 9 rotates, the telescopic end of the telescopic threaded cylinder 9 is extended, so that the telescopic threaded cylinder 9 can drive the detection rod 10 to be inserted into the soil.

[0046] In an embodiment of the present invention, the lower end of the drill bit 11 is flush with the pressure plate 1211, and the telescopic threaded tube 9 is threadedly connected to the axis of the fixed plate 121, and the detection rod 10 passes through the axis of the telescopic threaded tube 9, so that when the detection rod 10 is pressed down, the support frame 122 rotates with the ring 123 and the hinge plate 126, so that the detection rod 10 can be inserted a deeper distance, thereby making the detection range of the detection rod 10 larger.

[0047] In the present invention, when in use, the detection rod 10 of the magnetic exploration equipment is aligned with the target position, the motor is started, and the motor drives the sleeve 8 to drive the telescopic threaded cylinder 9 to rotate. The telescopic threaded cylinder 9 is threadedly connected with the fixed plate 121 so that the telescopic threaded cylinder 9 extends the telescopic end of the telescopic threaded cylinder 9 when rotating. At this time, the detection rod 10 moves with the telescopic end of the telescopic threaded cylinder 9, so that the detection rod 10 is smoothly inserted into the soil, and human insertion is prevented from causing the drill bit 11 to contact hard objects violently, causing damage to the drill bit 11, and reducing the use effect of the detection rod 10. When the telescopic threaded cylinder 9 is extended, the ring 123 drops accordingly. At this time, the ring 123 pulls the hinged plate 126 to rotate, so that the hinged plate 126 drives the support frame 122 to rotate, and the driving gear 127 rotates with the hinged plate 126, so that the driven gear meshed with it The gear 128 drives the tooth plate 129 to move, so that the tooth plate 129 pushes the pressure plate 1211 to rotate, so that when the support frame 122 rotates, the pressure plate 1211 always remains flush with the ground, so that the friction between the pressure plate 1211 and the ground is greater, so that the detection rod 10 is less likely to tip over. At this time, the pressure plate 1211 slides on the ground, and the pressure plate 1211 can slide better on the ground through the pulley. The arc block 1216 enables the pressure plate 1211 to move better when moving away from the detection rod 10. When moving toward the direction close to the detection rod 10, the friction is greater and it is difficult to move, preventing the support frame 122 from being hit and causing the detection rod 10 to be pulled out. After that, the detection rod 10 transmits the data to the console 1 through the transmission line 6. The user can query the data through the console 1 at this time to complete the exploration work.

[0048] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
