Description

Technical Field

[0001] This application relates to the field of orientation and distance detection technology in directional engineering exploration, and in particular to an orientation and distance detection device for directional engineering exploration. Background Technology

[0002] In directional engineering exploration, such as tunnel excavation, mineral drilling, and route surveying, accurate spatial orientation and distance measurement are crucial for ensuring project quality and precision. The core equipment widely used in such work is a directional orientation and distance measurement device that integrates optical, mechanical, and electrical technologies, capable of simultaneously measuring angles and distances. In the surveying industry, it is commonly referred to as a "total station." As a high-precision measuring instrument, the total station can complete all measurements of the station's horizontal angles, vertical angles, distances (slope distances and horizontal distances), and elevation differences with a single setup. Due to its high efficiency and accuracy, it has become an indispensable piece of equipment in precision engineering surveying, large-scale above-ground construction, and underground tunnel construction.

[0003] However, precisely because total stations play a crucial role in the aforementioned complex and demanding directional engineering exploration environments, they face severe challenges in practical use. Firstly, total stations are often used in complex locations such as construction sites and exploration routes, environments frequently teeming with people and machinery, and frequent vehicle traffic. Due to the complex and ever-changing external environment, unexpected situations can easily occur. For example, moving engineering vehicles or equipment may accidentally collide with the total station or its support, causing the total station to fall to the ground. Such an accidental fall can not only damage the instrument's outer casing but also potentially destroy its internal precision optical and electronic components, rendering the entire instrument unusable, resulting in significant economic losses and severely impacting project progress. Summary of the Invention

[0004] To address the problems existing in the above-mentioned technologies, this application provides a directional engineering exploration orientation and distance detection device.

[0005] The directional engineering exploration orientation and distance detection device provided in this application adopts the following technical solution:

[0006] A directional engineering exploration orientation and distance detection device includes a total station body and a mounting base. The total station body is mounted on the mounting base, and a support mechanism is provided on the side of the mounting base away from the total station body. A protective sleeve is slidably connected to the mounting base, and a positioning seat is provided on the mounting base. The bottom of the positioning seat can contact the ground. A first driving mechanism is provided on the mounting base. When the bottom of the positioning seat is not in contact with the ground, the first driving mechanism drives the protective sleeve to slide along the direction close to the total station body to cover the total station body.

[0007] By adopting the above technical solution, when the equipment is operating normally, the support mechanism supports the mounting base, thus fixing the total station body in place. The bottom of the positioning base is in contact with the ground, and the protective sleeve is located on the mounting base without obscuring the total station body, exposing it for orientation and distance detection. When the equipment is impacted and begins to tip over, the tilt will cause the positioning base to separate from the ground, meaning the bottom of the positioning base will no longer be in contact with the ground. This change in physical state serves as a trigger signal, activating the first drive mechanism. Under the operation of the first drive mechanism, the protective sleeve slides towards the total station body until it completely covers it. The coordination of the components in this process allows the protective sleeve to move to a position surrounding the total station body before it tipps over and collides with the ground. This rigid structure of the protective sleeve absorbs and disperses impact energy, providing a physical barrier for the delicate total station body inside and effectively reducing damage from the fall.

[0008] Optionally, the mounting base is provided with a locking component, which is used to fix the protective cover in the working position where the protective cover does not obstruct the total station body.

[0009] By adopting the above technical solution, when the equipment is performing normal directional exploration operations, the locking component is in working condition. It forms a mechanical interlock with the protective sleeve located in the working position, firmly fixing the protective sleeve in the working position and ensuring that the total station body is continuously exposed for interference-free and accurate measurement. When the equipment tilts and the positioning seat leaves the ground, the locking component releases its constraint on the protective sleeve, allowing it to be driven by the first drive mechanism to slide freely to the protective position. The entire working process ensures a reliable switch between the measurement accuracy under safe working conditions and the protective effectiveness under dangerous working conditions through the switching between the locked and unlocked states.

[0010] Optionally, a push rod is slidably mounted on the mounting base, and one end of the push rod away from the mounting base is slidably connected to the positioning base. The positioning base is provided with a fixing component for fixing the push rod. The mounting base has a mating groove for the top end of the push rod to slide into. The locking component includes a positioning rod slidably connected to the mounting base. The sliding direction of the positioning rod is not parallel to the sliding direction of the push rod. The protective sleeve has a positioning hole. One end of the positioning rod can be inserted into the positioning hole, and the other end can be inserted into the mating groove and abut against the push rod. The mounting base is provided with a reset part for driving the positioning rod away from the positioning hole.

[0011] By adopting the above technical solution, when the equipment is working normally, the bottom of the positioning seat is in contact with the ground, the protective sleeve is in a working position that does not cover the total station body, and the positioning hole is aligned with the positioning rod; then, the push rod is pushed upward, and the top of the push rod is inserted into the mating groove on the mounting seat. During the insertion process, the positioning rod whose end is in contact with the push rod is pushed, and the positioning rod moves away from the push rod to be inserted into the positioning hole. The position of the protective sleeve is thus fixed, and the push rod and the positioning seat are connected and fixed by the fixing component.

[0012] When the equipment is impacted and begins to tip over, the positioning seat loses contact with the ground and slides downwards under gravity. Under the action of the fixing components, the push rod is driven to slide downwards, and the top of the push rod slides away from the mating groove to release the push on the positioning rod. The positioning rod is then pulled out of the positioning hole by the reset part, releasing the mechanical lock of the protective sleeve and clearing the way for the first drive mechanism to perform its protective movement. This process transforms the equipment tipping state change into the linear motion of the positioning rod without delay through the linear motion of the push rod, ultimately achieving reliable release of the lock. It features direct force transmission, rapid action response, and high structural reliability.

[0013] Optionally, the mounting base has a drive groove, the reset part includes a first elastic element disposed in the drive groove, the positioning rod is provided with a drive block, the drive block is located in the drive groove and abuts against the first elastic element.

[0014] By adopting the above technical solution, in the locked state, when the top of the push rod is inserted into the mating groove and pushes the positioning rod so that one end is inserted into the positioning hole, the drive block on the positioning rod will compress the first elastic element in the drive groove, allowing it to store elastic potential energy. At this time, the insertion of the positioning rod overcomes the pressure of the first elastic element. When the equipment tilts to trigger unlocking and the top of the push rod no longer abuts against the end of the positioning rod, the pushing force of the push rod on the positioning rod disappears instantly. The compressed first elastic element immediately releases its stored potential energy, pushes the drive block, and drives the positioning rod to move rapidly in the lateral direction under the guidance of the drive groove, so that its end is reliably completely pulled out of the positioning hole of the protective sleeve. This process is an active, elastic force-driven automatic reset action, rather than passively relying on gravity or inertia. It clears the obstacle for the first drive component, which is about to be triggered, to drive the protective sleeve to move upward, ensuring the smooth start of the entire protective action.

[0015] Optionally, a second elastic element is provided in the mating groove, and the second elastic element abuts against the top end of the push rod.

[0016] By adopting the above technical solution, when the equipment is operating normally and the protective cover is locked in the working position, the operator presses the top of the push rod into the mating groove. This process simultaneously compresses the second elastic element within the mating groove, causing it to store elastic potential energy pointing outwards. At this time, the top of the push rod is held in this compressed position under external constraints (the fixing assembly connects the bottom of the push rod to the positioning seat, and the bottom of the positioning seat contacts the ground). When the equipment tilts until the positioning seat separates from the ground and the fixing constraint between the push rod and the mounting seat is released, the potential energy stored in the compressed second elastic element is immediately released, generating… A strong thrust acts on the top of the push rod, driving it to quickly pop downwards along the mounting base, disengaging its top from the mating groove. The downward movement of the push rod directly causes it to no longer press against the positioning rod, which is then pulled out of the positioning hole of the protective sleeve by the action of the reset part. This reliably releases the lock on the protective sleeve, providing the prerequisite for the first drive assembly to drive the protective sleeve upwards to complete the protective action. The entire unlocking process is passively triggered by mechanical components and actively driven by spring energy. It has a fast response speed and does not rely on external energy, ensuring the success rate of the protective system in emergency situations.

[0017] Optionally, the positioning seat has a first sliding hole, the push rod has a second sliding hole, and the fixing assembly includes positioning screws that pass through the first and second sliding holes simultaneously.

[0018] By adopting the above technical solution, during the equipment installation phase, the bottom of the positioning seat is in contact with the ground, the protective sleeve is in the working position, and the top of the push rod is inserted into the mating groove so that the end of the positioning rod is inserted into the positioning hole. At the same time, the end of the push rod away from the mounting seat slides on the positioning seat, and the first sliding hole and the second sliding hole are connected. After that, the positioning screw is passed through the aligned first and second sliding holes simultaneously, and the nut on the positioning screw is tightened so that the end of the positioning screw abuts against the outer wall of the positioning seat, and the nut of the positioning screw abuts against the outer wall of the other end of the positioning seat. The bottom end of the push rod is thus fastened to the positioning seat. The positioning screw rigidly fixes the push rod and the positioning seat into a whole in the vertical direction. At this time, a stable structural relationship is formed between the positioning seat, the push rod and the mounting seat, ensuring that the positioning rod works reliably. When the equipment tilts and the positioning seat is off the ground, the positioning seat drives the push rod to move downward synchronously through the rigidly connected positioning screw, thereby triggering the subsequent unlocking sequence.

[0019] Optionally, the first drive mechanism includes a third elastic element, and the protective sleeve has an extension at one end away from the positioning seat, with the third elastic element located between the extension and the mounting seat.

[0020] By adopting the above technical solution, when the equipment is set up normally and the protective cover is in the working position of the total station without obstructing it, the third elastic element located between the extension and the mounting base is in a compressed state, storing a large amount of elastic potential energy. When the equipment tilts and the positioning base is lifted off the ground, the locking component releases the constraint on the protective cover, and the elastic potential energy stored in the compressed third elastic element is immediately released, generating a rebound force that pushes the extension on the protective cover and drives the entire protective cover to slide along the direction closer to the total station body, so as to build a solid physical barrier in advance before the total station body violently impacts the ground.

[0021] Optionally, the outer wall of the protective sleeve is fitted with a flexible pad.

[0022] By adopting the above technical solution, during normal equipment movement or operation, the flexible pad on the outer wall of the protective sleeve provides operators with a soft, non-slip grip surface, improving operational comfort and stability. When the equipment tips over due to an accidental collision, and the protective sleeve triggers and covers the total station body, the flexible pad on its outer wall will first undergo elastic or plastic deformation when the protective sleeve impacts the ground or other hard objects. Through its own compression, extension, or tearing, it dissipates a large amount of impact kinetic energy, transforming the violent instantaneous impact into a relatively gentle deceleration process. This significantly reduces the peak impact force transmitted to the rigid shell of the protective sleeve and the internal total station body, effectively preventing the protective sleeve from deforming and breaking due to bumps, and providing crucial secondary buffer protection for the internal precision instruments. At the same time, the flexible pad isolates the metal or hard plastic shell of the protective sleeve from direct contact with the rough ground, preventing the protective sleeve surface from being scratched or worn.

[0023] Optionally, the bottom of the positioning seat is provided with multiple protective support plates that can contact the ground, and the bottom of the protective support plates is provided with anti-slip pads.

[0024] By adopting the above technical solution, during normal equipment setup, multiple protective support plates at the bottom of the positioning base and their anti-slip pads on their lower surfaces are in contact with the ground. The structure of the protective support plates increases the contact area between the positioning base and the ground, reducing local pressure and preventing it from sinking on soft ground (such as sand or mud). The anti-slip pads, with their high coefficient of friction, provide excellent anti-slip capability, preventing slippage on slopes or smooth, hard surfaces (such as cement or rock). Together, they ensure the stable support of the positioning base in complex exploration terrain, providing a stable and reliable measurement benchmark for the total station. When the equipment is subjected to an accidental collision, the positioning base will not immediately slide or sink due to the stable grip provided by the protective support plates and anti-slip pads. Only when the overturning moment is large enough to cause the entire equipment to lift will the positioning base separate from the ground. This process ensures the accuracy and uniqueness of the trigger signal, effectively avoiding false triggering caused by slippage of the support feet. Throughout the entire working process, the structure of the protective support plates and anti-slip pads effectively protects the bottom of the positioning base, reduces wear, and extends its service life.

[0025] Optionally, the support mechanism includes multiple telescopic legs, each of which is hinged to the side of the mounting base away from the total station body; a clearance groove is provided on the protective sleeve corresponding to the position of each telescopic leg to provide clearance space when the telescopic leg rotates.

[0026] By adopting the above technical solution, during the equipment design phase, based on the motion trajectory of the telescopic outriggers when rotating and retracting around their hinge points with the mounting base, clearance grooves with matching contours are precisely opened on the protective sleeve. This design allows the hinge points between multiple telescopic outriggers and the mounting base to be distributed around the outer periphery of the bottom of the mounting base, rather than concentrated in the center. Thus, when the equipment is deployed, each outrigger can support the ground with a larger span, providing a stable support system with a larger support base and a better lever arm distribution for the mounting base and the total station body above it, effectively resisting lateral forces and moments and preventing overturning. When the equipment needs to be stored and transported, the operator rotates the outriggers towards the center of the mounting base to retract them. During the rotation, the outriggers smoothly enter and exit the corresponding clearance grooves on the protective sleeve along their preset trajectory, avoiding structural interference with the protective sleeve wall, allowing the protective sleeve to still slide freely to cover or expose the instrument.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The cooperation of the various components in this application enables the protective sleeve to move to a position covering the periphery of the total station body before the equipment tilts and collides with the ground. This allows the rigid structure of the protective sleeve to absorb and disperse the impact energy, providing a physical barrier for the internal precision total station body and effectively reducing the damage caused by the fall.

[0029] 2. When the equipment is performing directional exploration operations normally, the locking component is in the working state. It forms a mechanical interlock with the protective sleeve located in the working position, which firmly fixes the protective sleeve in the working position, ensuring that the total station body is continuously exposed for interference-free and accurate measurement. When the equipment tilts and the positioning seat leaves the ground, the locking component releases its constraint on the protective sleeve, allowing it to be driven by the first drive mechanism to slide freely to the protective position. The entire working process ensures a reliable switch between the measurement accuracy under safe working conditions and the protective effectiveness under dangerous working conditions through the switching between the locked and unlocked states.

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] This application discloses a device for detecting directional orientation and distance in directional engineering exploration. (Refer to...) Figures 1-7 The directional engineering exploration orientation and distance detection equipment includes a total station body 1 and a mounting base 2. The total station body 1 is mounted on the mounting base 2. A support mechanism 3 is provided on the side of the mounting base 2 away from the total station body 1. A protective sleeve 4 is slidably connected to the mounting base 2. A positioning seat 5 is provided on the mounting base 2. The bottom of the positioning seat 5 can contact the ground. A first drive mechanism 6 is provided on the mounting base 2. When the bottom of the positioning seat 5 is not in contact with the ground, the first drive mechanism 6 drives the protective sleeve 4 to slide along the direction close to the total station body 1 to cover the total station body 1.

[0040] Reference Figures 1-6 The mounting base 2 is equipped with a locking component 7, which is used to fix the protective sleeve 4 in a working position where the protective sleeve 4 does not cover the total station body 1. A push rod 8 is slidably mounted on the mounting base 2. The top end of the push rod 8 is vertically slidably connected to the mounting base 2, and the bottom end of the push rod 8 is vertically slidably connected to the positioning base 5. The positioning base 5 is equipped with a fixing component 9 for fixing the push rod 8. The mounting base 2 has a mating groove 10 for the top end of the push rod 8 to slide into. The mating groove 10 is connected to the outside. The locking component 7 includes a positioning rod 701 slidably connected to the mounting base 2. The mounting base 2 has a through hole for the positioning rod 701 to pass through and slide. The sliding direction of the positioning rod 701 is perpendicular to the sliding direction of the push rod 8. The protective sleeve 4 has a positioning hole 11. One end of the positioning rod 701 can be inserted into the positioning hole 11, and the other end can be inserted into the mating groove 10 and abut against the push rod 8. The mounting base 2 is equipped with a reset part 12 for driving the positioning rod 701 away from the positioning hole 11.

[0041] When the equipment is working normally, the bottom of the positioning seat 5 is in contact with the ground, and the protective sleeve 4 is in a working position that does not cover the total station body 1. The positioning hole 11 is aligned with the positioning rod 701. Then, the push rod 8 is pushed upward, and the top of the push rod 8 is inserted into the mating groove 10 on the mounting seat 2. During the insertion process, the positioning rod 701, whose end is in contact with the push rod 8, is pushed. The positioning rod 701 moves away from the push rod 8 to insert into the positioning hole 11, and the position of the protective sleeve 4 is fixed. The push rod 8 and the positioning seat 5 are connected and fixed by the fixing component 9. When the equipment is impacted and begins to overturn, the positioning seat 5 is no longer in contact with the ground. The positioning seat 5 will slide downward under the action of gravity. Under the action of the fixing component 9, the push rod 8 is driven to slide downward. The top of the push rod 8 slides away from the mating groove 10 to release the push on the positioning rod 701. The positioning rod 701 is pulled out from the positioning hole 11 under the action of the reset part 12. The mechanical lock of the protective sleeve 4 is released, clearing obstacles for the first drive mechanism 6 to drive it to perform protective movement.

[0042] Reference Figures 1-6 In this embodiment, to improve the stability of the protective sleeve 4 when it is fixed in the working position, a plurality of positioning rods 701 are provided on the mounting base 2. The plurality of positioning rods 701 are arranged at intervals along the circumferential direction of the mounting base 2. A plurality of positioning holes 11 are provided on the protective sleeve 4, and the position of each positioning hole 11 corresponds to a positioning rod 701. Each positioning hole 11 can be used to insert the end of the corresponding positioning rod 701. In order to improve the flexibility of the triggering process of the positioning rod 701 being pushed by the push rod 8, the end face of the positioning rod 701 located in the positioning hole 11 is flat. The cross-section of the end of the positioning rod 701 located at the groove opening of the mating groove 10 gradually decreases along the direction close to the push rod 8. On the cross-section perpendicular to the length direction of the positioning rod 701, the cross-section of the end of the positioning rod 701 located at the groove opening of the mating groove 10 is hemispherical.

[0043] Reference Figures 1-6 The mounting base 2 has a drive groove 13. The reset part 12 includes a first elastic element 1201 disposed in the drive groove 13. A drive block 1202 is disposed on the positioning rod 701. The drive block 1202 is located in the drive groove 13 and abuts against the first elastic element 1201. A second elastic element 14 is disposed in the mating groove 10. The second elastic element 14 abuts against the top of the push rod 8. The first drive mechanism 6 includes a third elastic element 601. An extension 18 is disposed at the end of the protective sleeve 4 away from the positioning base 5. The third elastic element 601 is located between the extension 18 and the mounting base 2.

[0044] When the equipment is working normally and the protective sleeve 4 is locked in the working position, the third elastic element 601 located between the extension 18 and the mounting base 2 is in a compressed state, and the third elastic element 601 stores a large amount of elastic potential energy. When the operator presses the top of the push rod 8 into the mating groove 10, the second elastic element 14 in the mating groove 10 is compressed at the same time, so that it stores elastic potential energy pointing out of the groove. At this time, the top of the push rod 8 is held in the compressed position under external constraints (the fixing component 9 connects the bottom of the push rod 8 to the positioning base 5, and the bottom of the positioning base 5 is in contact with the ground). At the same time, the drive block 1202 on the positioning rod 701 will compress the first elastic element 1201 in the drive groove 13, so that it stores elastic potential energy. At this time, the insertion of the positioning rod 701 overcomes the pressure of the first elastic element 1201. When the device tilts to the moment the positioning seat 5 separates from the ground and the fixed constraint between the push rod 8 and the mounting seat 2 is released, the top of the push rod 8 no longer abuts against the end of the positioning rod 701. The potential energy stored in the compressed second elastic element 14 is immediately released, generating a strong thrust on the top of the push rod 8, driving the push rod 8 to quickly pop down along the mounting seat 2, causing its top to disengage from the mating groove 10. Subsequently, the compressed first elastic element 1201 immediately releases its stored potential energy, pushing the drive block 1202 and, guided by the drive groove 13, causing the positioning rod 701 to move quickly in the lateral direction, so that its end can be reliably pulled out completely from the positioning hole 11 of the protective sleeve 4, thereby releasing the lock on the protective sleeve 4. The elastic potential energy stored in the compressed third elastic element 601 is immediately released, generating a rebound force, pushing the extension 18 on the protective sleeve 4, and then driving the entire protective sleeve 4 to slide in the direction close to the total station body 1, so as to build a solid physical barrier in advance before the total station body 1 violently impacts the ground.

[0045] Reference Figures 1-6In this embodiment, the first elastic element 1201 is selected as a first push spring. The first push spring is horizontally arranged and located in the drive groove 13. One end of the first push spring is fixed in the drive groove 13, and the other end is fixedly connected to the drive block 1202. In order to improve the stability of the positioning rod 701 during the reset process, multiple drive grooves 13 are provided in the mounting base 2. Each positioning rod 701 has a drive groove 13 on both sides. Each drive groove 13 is provided with a first push spring and a drive block 1202. The second elastic element 14 is selected as a second push spring arranged vertically. The first push spring is located in the mating groove 10. One end of the second push spring is fixedly connected to the groove end wall of the mating groove 10, and the other end is fixedly connected to the plane of the top end of the push rod 8. The extension 18 is a ring plate 1801 fixed to the top of the protective sleeve 4. The ring plate 1801 is on the same central axis as the protective sleeve 4. The diameter of the inner ring of the ring plate 1801 is smaller than the diameter of the protective sleeve 4. The third elastic element 601 is a vertically arranged third push spring. Multiple third push springs are provided and distributed at intervals along the circumference of the mounting base 2. Multiple third push springs are all provided on the top of the mounting base 2. One end of the third push spring is fixedly connected to the mounting base 2, and the other end is fixedly connected to the bottom surface of the ring plate 1801.

[0046] Reference Figures 1-6 The outer wall of the protective sleeve 4 is fitted with a flexible pad (not shown in the figure). The flexible pad is sleeve-shaped, and the inner wall of the flexible pad is in contact with the outer wall of the protective sleeve 4. The flexible pad is detachably connected to the protective sleeve 4 and does not contact the extension 18 and the support seat to avoid interfering with the sliding of the protective sleeve 4. The bottom of the positioning seat 5 is provided with multiple protective support plates 19 that can contact the ground. The bottom of the protective support plate 19 is fixed with an anti-slip pad (not shown in the figure).

[0047] When the equipment is normally erected, the multiple protective support plates 19 at the bottom of the positioning base 5 and the anti-slip pads on its lower surface are in contact with the ground. The structure of the protective support plates 19 increases the contact area between the positioning base 5 and the ground, reduces local pressure, and prevents it from sinking on soft ground (such as sand or mud). This ensures the stable support of the positioning base 5 in complex exploration terrain and provides a stable and reliable measurement benchmark for the total station. When the equipment is subjected to an accidental collision, the positioning base 5 will not immediately slide or sink due to the stable grip provided by the protective support plates 19 and the anti-slip pads. Only when the overturning moment is large enough to cause the entire equipment to lift will the positioning base 5 separate from the ground. This process ensures the accuracy and uniqueness of the trigger signal and effectively avoids false triggering caused by the slippage of the support feet.

[0048] Reference Figures 1-5 The positioning seat 5 has a long, narrow first sliding hole 15, and the push rod 8 has a long, narrow second sliding hole 16. The fixing component 9 includes a positioning screw 901 that passes through the first sliding hole 15 and the second sliding hole 16 simultaneously.

[0049] During the equipment installation phase, the bottom of the positioning seat 5 is brought into contact with the ground, the protective sleeve 4 is in the working position, and the top of the push rod 8 is inserted into the mating groove 10 so that the end of the positioning rod 701 is inserted into the positioning hole 11. At the same time, the end of the push rod 8 away from the mounting seat 2 slides on the positioning seat 5, and the first sliding hole 15 communicates with the second sliding hole 16. After this, the positioning screw 901 is passed through the aligned first sliding hole 15 and second sliding hole 16 simultaneously, and the nut on the positioning screw 901 is tightened so that the end of the positioning screw 901 abuts against the outer wall of the positioning seat 5, and the nut of the positioning screw 901 abuts against the outer wall of the other end of the positioning seat 5. The bottom end of the push rod 8 is thus pressed and fastened to the positioning seat 5. The positioning screw 901 rigidly fixes the push rod 8 and the positioning seat 5 into a whole in the vertical direction. At this time, a stable structural relationship is formed between the positioning seat 5, the push rod 8 and the mounting seat 2, ensuring that the positioning rod 701 works reliably.

[0050] Reference Figure 1 and Figure 5 In this embodiment, to increase the sliding range of the push rod 8, the bottom end of the push rod 8 is slidable and fixed to the positioning seat 5 through the cooperation of the positioning screw 901, the first sliding hole 15, and the second sliding hole 16. (Refer to...) Figure 7 In other embodiments, to improve the convenience of fixing the bottom of the push rod 8, multiple first insertion holes 21 can be opened on the push rod 8 along the length direction of the push rod 8, and multiple second insertion holes 22 can be opened on the positioning seat 5 along the length direction of the positioning seat 5. The fixing component 9 is selected as a horizontally arranged positioning pin 902, and the positioning pin 902 can be simultaneously inserted into a first insertion hole 21 and a second insertion hole 22.

[0051] Reference Figures 1-5 The support mechanism 3 includes multiple telescopic legs 301, each of which is hinged to the side of the mounting base 2 away from the total station body 1. A clearance groove 20 is provided on the protective sleeve 4 corresponding to the position of each telescopic leg 301 to provide clearance space when the telescopic leg 301 rotates to the storage position.

[0052] During the equipment design phase, based on the movement trajectory of the telescopic outriggers 301 as they rotate and retract around their hinge points with the mounting base 2, clearance grooves 20 with matching contours are precisely cut into the protective sleeve 4. This design allows the hinge points between the multiple telescopic outriggers 301 and the mounting base 2 to be distributed around the outer periphery of the bottom of the mounting base 2, rather than concentrated in the center. This allows each outrigger to support the ground with a larger span when the equipment is deployed, providing a stable support system with a larger support base and a better lever arm distribution for the mounting base 2 and the total station body 1 above it. This effectively resists lateral forces and moments and prevents overturning.

[0053] In this embodiment, considering the above considerations, a clearance groove 20 is provided on the protective sleeve 4; in other embodiments, in order to improve the protective effect of the protective sleeve 4, the position of the total station can be adjusted by concentrating the junction point of the telescopic support leg 301 and the mounting base 2 on the bottom of the mounting base 2, or by changing the overall length of the telescopic support leg 301, thereby eliminating the need to provide a corresponding clearance groove 20 on the protective sleeve 4.

[0054] Reference Figures 1-5 In this embodiment, to improve the stability of the positioning seat 5 during sliding, multiple connecting rods 23 are provided on the positioning seat 5. The connecting rods 23 are horizontally arranged, and a vertically arranged first sliding groove 24 is opened at the bottom of the protective sleeve 4. A vertically arranged first sliding plate 25 slides in the first sliding groove 24. One end of the connecting rod 23 is fixedly connected to the first sliding plate 25, and the other end is fixedly connected to the outer wall of the positioning seat 5. During the sliding of the positioning seat 5, the first sliding plate 25 is driven by the connecting rod 23 to slide in the first sliding groove 24. The above arrangement establishes a connection between the protective sleeve 4 and the positioning seat 5, which is beneficial to the overall stability and uniformity of the equipment. The positioning seat 5 is connected to the mounting base 2 through the connection with the protective sleeve 4 and the push rod 8. (Refer to...) Figure 4 In other embodiments, a vertically arranged second slide groove 26 can be opened at the bottom of the mounting base 2. A vertically arranged second slide plate 27 is slidably arranged in the second slide groove 26. One end of the connecting rod 23 is fixedly connected to the second slide plate 27, and the other end is fixedly connected to the outer wall of the positioning base 5. During the sliding process of the positioning base 5, the second slide plate 27 is driven by the connecting rod 23 to slide in the second slide groove 26, thereby establishing a connection between the positioning base 5 and the mounting base 2.

[0055] In this embodiment, the connection and telescopic adjustment method between the multiple telescopic legs 301 of the support mechanism 3 and the mounting base 2 adopts a conventional structure known in the tripod field. The upper ends of the multiple telescopic legs 301 are hinged to the bottom of the mounting base 2 via a hinge plate, allowing the legs to be extended or retracted relative to the mounting base 2. Each telescopic leg 301 is composed of multiple leg tubes connected together, and adjacent leg tubes are fixed together by a conventional locking device with a screw-type locking structure. When the height needs to be adjusted, the locking device is loosened, the leg tube is pulled out to the required length, and then it is relocked.

[0056] The connection between the total station body 1 and the mounting base 2 adopts a conventional connection method known in the surveying field. A standard interface (not shown in the figure) is provided at the center of the bottom of the total station body 1; correspondingly, a threaded hole (not shown in the figure) matching the standard interface is machined at the center of the upper surface of the mounting base 2. By screwing the connecting screw at the bottom of the total station body 1 into the threaded hole of the mounting base 2 and tightening it, the total station body 1 can be quickly and reliably fixed on the mounting base 2.

[0057] The working process of this application embodiment:

[0058] Normal measurement: Set up the telescopic support 301 so that the positioning seat 5 touches the ground; push the protective sleeve 4 upward to the working position (total station exposed), compressing the third push spring; push the push rod 8 upward so that its top end compresses the second push spring and inserts into the mating groove 10, and pushes the positioning rod 701 to overcome the force of the first push spring and insert it into the positioning hole 11 of the protective sleeve 4; lock the push rod 8 with the positioning screw 901; the total station performs the measurement.

[0059] Trigger protection: The collision causes the equipment to tilt and the positioning seat 5 to leave the ground; the second push spring rebounds, the push rod 8 moves down, and the top part disengages from the mating groove 10, no longer pushing the positioning rod 701; the first push spring pushes the positioning rod 701 out of the positioning hole 11 and releases the lock; the third push spring rebounds, driving the protective sleeve 4 to rise and cover the total station, and the flexible pad buffers the impact of landing.

[0060] The implementation principle of the orientation and distance detection device for directional engineering exploration according to this application embodiment is as follows: When the device is operating normally, the device supports the mounting base 2 through the support mechanism 3, thereby supporting and fixing the total station body 1. At this time, the bottom of the positioning seat 5 is in contact with the ground, and the protective sleeve 4 is located on the mounting base 2 without covering the total station body 1. The total station body 1 is exposed at this time, thus performing orientation and distance detection operations. When the device is impacted and begins to tip over, the tilt of the device will cause the positioning seat 5 to separate from the ground, that is, the bottom of the positioning seat 5 will no longer be in contact with the ground. This change in physical state is a trigger signal, and the first drive mechanism 6 is activated at this time. Under the operation of the first drive mechanism 6, the protective sleeve 4 slides in the direction close to the total station body 1 until it covers the total station body 1. The cooperation of the various components in the above process allows the protective sleeve 4 to move to a position covering the periphery of the total station body 1 before the device tipps over and collides with the ground. Thus, the rigid structure of the protective sleeve 4 absorbs and disperses the impact energy, providing a physical barrier for the internal precision total station body 1, effectively reducing the damage caused by the fall.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
