It should be understood that the drawings and embodiments of the present disclosure are for illustration purposes only and are not intended to limit the scope of the present disclosure.

It should be further noted that, for convenience of description, only the portions related to the present application are shown in the drawings. Embodiments of the present disclosure and features of embodiments may be combined with each other without conflict.

It should be noted that references to "one", "a plurality" and "a plurality" in this disclosure are intended to be illustrative rather than limiting, and those of ordinary skill in the art will appreciate that "one or more" is intended to be understood as "one or more" unless the context clearly indicates otherwise.

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1 to 17, some embodiments of the present application provide a detection apparatus 100, including: the probe 101, the data interface 102, the housing 103, the first terminal 106, the second terminal 107, and the charging interface 108.

The detector head 101 is used to collect detection data. The data interface 102 is used for transmitting probe data. The housing 103 is used to secure the data interface 102.

The probe 101 is arranged at the front end of the housing 103, enabling the probe 101 to collect probe data at various depth positions of the borehole after the housing 103 has been pushed into the borehole by external machine equipment, such as the rock drilling rig 200. The rear end of the housing 103 is formed with a mounting interface for coupling the sonde 100 to one drill rod 201, i.e. the sonde 100 can be connected to the drill rod 201 of the rock drilling rig 200 via the mounting interface so as to be pushed into the borehole under the drive of the drill rod 201.

Considering that the end of the drill rod 201 of the rock drilling rig 200 is generally provided with external threads for connecting a drill bit, referring to fig. 3, the mounting interface may be configured as an opening 103a provided at the rear end of the housing 103, and an internal thread 103b provided in the opening 103a, so as to screw-couple the sonde 100 as a whole to one end of the drill rod 201.

The mounting interface may also be configured to be secured to external devices, such as the rock drilling rig 200, capable of driving the sonde 100 to move within the borehole using a bayonet connection, riveting, welding, interference fit, etc., to drive the sonde 100 to move through these external devices. The internal thread 103b illustrated in the present application should be regarded as an example of a manner in which the housing 103 is connected to an external device, and should not be regarded as that the housing 103 can be detachably fixedly connected to the external device only by the internal thread 103 b.

Correspondingly, the rock drilling rig 200 should be regarded as an illustration of an external device driving the detection apparatus 100 to move within the borehole, and should not be regarded as if the detection apparatus 100 could only cooperate with the rock drilling rig 200 to perform the detection work.

The data interface 102 is arranged between the probe head 101 and the mounting interface so that after the probe apparatus 100 is moved out of the borehole, external terminal devices capable of receiving probe data can retrieve the probe data from the data interface 102.

Through the scheme, the data interface 102 is connected to the external terminal to call the detection data, and compared with the existing mode of acquiring the image in real time only during construction, the method has the advantages that the image data can be called according to the need after detection, and the call of the shot image is more convenient. The time for analyzing the geological structure of the drilled hole can be reserved for the user, so that subsequent exploration, blasting and other works can be guided better.

The detection device 100 may be powered by an external power source. Preferably, however, the detection device 100 comprises: a battery 104 and a circuit board 105. The battery 104 is used to power the probe 101. To mount the battery 104, the housing 103 is defined to include: a first pod 103c. The first housing 103c is used for accommodating the battery 104, that is, the battery 104 is mounted in the housing 103, and the battery 104 is protected by the housing 103, so that the detection device 100 can house the battery 104. The detection device 100 can enable the detection head 101 to complete the work of collecting detection data without the need of an external power supply.

In a specific embodiment, in order for the data interface 102 to complete data transmission, the probe apparatus 100 includes: a circuit board 105. The circuit board 105 is used for forming an electrical connection with the data interface 102. To mount the circuit board 105, the housing 103 is defined to include: a second pod 103d. The second housing 103d is used to house the circuit board 105 such that the circuit board 105 moves synchronously with the probe apparatus 100. The first housing 103c and the second housing 103d form a detachable fixed connection.

Through the scheme, the detection device 100 does not need to pull a power line from the outside to supply power for the detection head 101 in the detection process in the drilling hole, so that the site construction is facilitated. And the first housing 103c may be separated from the second housing 103d after the detection is completed, so as to charge the battery 104 in the first housing 103c or to replace the battery 104. The data interface 102 is still electrically connected to the circuit board 105, so that the data interface 102 can be used independently to retrieve probe data or can be powered by an external power source or other battery 104 to be used normally.

As a specific solution for electrically connecting the battery 104 and the probe 101, the probe apparatus 100 further includes: a first terminal 106 and a second terminal 107. Wherein the first terminal 106 is mounted to the first housing 103c and is electrically connected to the battery 104. The second terminal 107 is mounted to the second housing 103d and is electrically connected to the probing tip 101. The first and second terminals 106 and 107 are in contact to form an electrical connection when the first and second housings 103c and 103d form a fixed connection, i.e., the battery 104 is electrically connected to the second terminal 107 through the first terminal 106, and the battery 104 is further electrically connected to the probe 101 by means of a cable or soldering.

The first cabin shell 103c and the second cabin shell 103d can form detachable fixed connection through the modes of threaded connection, snap connection, eyelet pin shaft fit, interference fit and the like.

Referring to fig. 5 and 6, a specific implementation solution of the first terminal 106 and the second terminal 107 is illustrated when the first housing 103c and the second housing 103d form a threaded connection: the first terminals 106 are configured as a plurality of conductive metal rings formed on a PCB board, each metal ring being concentrically disposed and electrically connected to an electrode of the battery 104, respectively. Correspondingly, the second terminals 107 are configured as a plurality of retractable metal terminals formed on another PCB board, and the metal terminals may be retractable with respect to the PCB board in a specific manner by providing springs or the like therebetween. The metal terminals are electrically connected to the probe head 101. During the screwing of one end of the first housing 103c to the second housing 103d, the metal terminals are in contact with the concentric conductive metal rings, so that after the first housing 103c is fixedly mounted on one end of the second housing 103d, the first terminals 106 are in contact with the second terminals 107, and the electrical connection between the battery 104 and the probe 101 is achieved.

Referring to fig. 4, a first housing 103c may be provided to be secured between the probing tip 101 and a second housing 103d, where one end of the first housing 103c may be provided with a set of first and second terminals 106, 107 to make electrical connection with the probing tip 101. The second housing 103d may further be provided with another set of first terminals 106 and second terminals 107, and one of the first terminals 106 and the second terminals 107 is electrically connected to the probe 101, and the other is electrically connected to the circuit board 105, so as to achieve electrical connection between the probe 101 and the data interface 102.

Referring to fig. 5, it may also be configured that a mounting interface is formed in the first housing 103c, that is, the first housing 103c is disposed at an end of the probing apparatus 100 remote from the probing tip 101 and is capable of being coupled to an external device through the mounting interface.

The probe apparatus 100 may include: a charging interface 108. Wherein the charging interface 108 is used to introduce the electrical energy required to charge the battery 104. The charging interface 108 is electrically connected to the battery 104, i.e. the battery 104 is a rechargeable battery 104, such as a lithium battery 104. A charging interface 108 may be provided on the second housing 103c and electrically connected to the battery 104 by mating the first terminal 106 with the second terminal 107.

Referring to fig. 5, a charging interface may also be provided at the end of the first housing 103c facing the second housing 103d to be located inside the housing 103 when the first housing 103c and the second housing 103d form a fixed connection. I.e. the charging interface 108 can be shielded by the housing 103 during normal use of the detection device 100. After the detection, the charging interface 108 can be exposed by separating the first housing 103c from the second housing 103d, so that the battery 104 can be charged by connecting the charging interface 108 with a power source.

Referring to fig. 7, when the mounting interface is configured as an opening 103a provided at the rear end of the housing 103, a chamber in which the first pod 103c can house the battery 104 may be configured to communicate with the opening 103 a. At this time, the charging port 108 is not required, but the battery 104 can be taken out from the opening 103a to be replaced or charged. And a fixing bolt 103e may be further provided on the first housing 103c, and after the battery 104 is put into the chamber of the first housing 103c in which the battery 104 is accommodated, the battery 104 is locked by screwing the fixing bolt 103e, and fixed in the first housing 103c.

The housing 103 further includes: and a third pod 103f. Wherein the third housing 103f is adapted to house at least a portion of the probe 101. The second housing 103d is disposed between the first housing 103c and the third housing 103f. That is, the third housing 103f is provided at the front end of the probe apparatus 100, and the probe 101 is fixedly mounted using the third housing 103f.

The third pod 103f is removably and fixedly coupled to the second pod 103d to enable replacement of unused types of the probe 101 as needed for subsequent construction to select the type of probe data collected by the probe 101.

For example, referring to fig. 8, the probe 101 may be configured as an ultrasonic radar 101a, a millimeter wave detector, a thermal imager, etc. provided at the front end of the third housing 103f to correspondingly acquire ultrasonic imaging data, millimeter wave imaging data, thermal imaging data, etc. during the movement of the probe device 100 within the borehole.

Referring to FIG. 9, the probe 101 may be configured to include: a camera 101b. The camera 101b is used for acquiring image data, and at this time, the image data acquired by the camera 101b can be utilized to enable a user to know information such as protrusions, grooves, hole wall cracks and the like in a drill hole.

The third pod 103f may be provided with a light source 101c at a front end thereof. The light source 101c is electrically connected with the battery 104, so that the battery 104 is used for supplying power to the light source 101c, and the light source 101c is used for illuminating in the drill hole, so that the camera 101b obtains clearer image data.

The camera 101b preferably employs a fisheye camera 101b, which can obtain a larger angle of view to obtain a larger shooting range.

The light source 101c may be a plurality of LED lamps, and the LED lamps are disposed at the periphery of the camera 101b. The light source 101c is now closer to the borehole wall to enhance illumination of the wall.

Referring to fig. 10, a light-transmitting cover 101d may be fixedly provided at the front end of the third housing 103f, and the camera 101b may be provided in a protection space formed by surrounding the light-transmitting cover 101d and the third housing 103f. The transparent cover 101d can be made of transparent acrylic, glass and other materials, the front end of the transparent cover is hemispherical, so that interference of shooting of the camera 101b is reduced, an eggshell-like structure is formed, broken stones easily fall off the hole wall when a drill hole and the like transversely opened on a mountain body are detected, and the broken stones falling off the hole wall can be prevented from colliding with the camera 101b by the transparent cover 101 d.

The light source 101c is disposed at the periphery of the transparent cover 101d, so as to reduce the possibility of overexposure of the image captured by the camera 101b, which is caused by the direct collection of the light emitted by the light source 101c in the transparent cover 101d due to reflection.

The portion of the camera 101b that captures the image and the translucent cover 101d are located at the front end of the third housing 103f with respect to the light source 101c, for example, a portion of the outer wall surface of the third housing 103f may be protruded from the light source 101c, and the camera 101b and the translucent cover 101d may be disposed at the front end of the protruded wall surface. At this time, at least a part of the light emitted from the light source 101c to the camera 101b may be reflected or absorbed by the wall surface of the third housing 103f, so as to further reduce the possibility of overexposure of the camera 101b.

An adjustment switch may be provided on the first/second/third housings 103c, 103d, 103f, and electrically connected between the battery 104 and the probe 101 to control the on/off of the electrical circuit between the probe 101 and the battery 104 by controlling the adjustment switch.

The adjusting switch may be electrically connected to the light source 101c and the battery 104, so as to adjust the on-off of the circuit between the battery 104 and the light source 101c and the brightness of the light source 101c when illuminated. The regulating switch is preferably provided on the second housing 103d. For example, referring to fig. 11, the adjusting switch includes a knob rotatably provided on the second housing 103d and a variable resistor 110 connected to the knob inside the second housing 103d. The variable resistor 110 is electrically connected to the circuit board 105, and is electrically connected to the battery 104 and the light source 101c through the circuit board 105. Thus, the brightness of the light source 101c can be adjusted by turning the knob to change the resistance of the variable resistor 110.

As a specific implementation, the data interface 102 includes: a reader and a video interface 102a.

The reader/writer and the video interface 102a are electrically connected to the circuit board 105 by cables or soldering, respectively. The reader/writer is used for reading and writing the image data to a storage medium, which may be an SD card, a TF card, memory particles soldered to the circuit board 105, or the like. When the storage medium is a memory pellet soldered to the circuit board 105, the reader/writer may be regarded as a memory chip combining several memory pellets. When the storage medium is an SD card, a TF card, or the like, the reader/writer may be configured to fix the memory card slot interface 102b provided on the second pod 103d for insertion of the storage medium, so that after the storage medium stores the probe data collected by the probe 101, the storage medium can be removed from the reader/writer, and at this time, the storage medium may be mounted on a terminal device capable of reading the probe data, thereby implementing offline use of the probe data.

The video interface 102a is used to transmit image data to an external display device. The video interface 102a may be an HDMI interface, a type-c interface, or the like, and may retrieve image data after being connected to a display device using a corresponding data signal line. Before the detection device 100 performs formal detection, the video interface 102a is externally connected to the display device to debug the brightness of the camera 101b and the light source 101c, so that the camera 101b can acquire clear image data after entering a borehole.

Referring to fig. 11, the video interface 102a and the memory card slot interface 102b are preferably fixedly disposed on the second pod 103d so that they are spatially closer to the circuit board 105 to simplify the electrical circuit between them and the circuit board 105. A shield 103g, which is detachably and fixedly connected to the housing 103, may be provided outside the portion of the second casing 103d where the video interface 102a and the memory card slot interface 102b are fixedly provided. The shield 103g surrounds the exterior of the video interface 102a or the card slot to protect both. The shield 103g may be provided outside the adjustment switch.

In order to make the detection data more practical, a component capable of acquiring the position information of the detection device 100 in the drill hole may be disposed between the second capsule 103d and the third capsule 103f, so as to correspond the position information to the acquired detection information, so that the specific position of the hole wall crack and the like in the drill hole can be clarified when the detection information is acquired later.

Referring to fig. 12, the parts for acquiring the position information of the probe apparatus 100 may employ a UWB chip 111 fixedly disposed inside the housing 103 and electrically connected to the circuit board 105 and the storage medium, and at this time, a UWB transmitting or receiving terminal may be disposed outside the borehole, so that the position information of the probe apparatus 100 is acquired by using a UWB communication positioning technology in cooperation with the UWB chip 111 and the terminal outside the borehole. The technical improvement of the UWB communication positioning technology is not made in the scheme, and the structure and the technical principle of the technical improvement are not repeated here.

As another particularly feasible embodiment for collecting the position information of the detection device 100, the detection device 100 further includes: a ranging wheel 112 and a grating encoder 113. Wherein the ranging wheel 112 is rotatably connected to the housing 103, and the ranging wheel 112 contacts and rolls at the borehole wall during movement of the sonde 100 within the borehole. The grating encoder 113 comprises a code disc 113a capable of being linked with the ranging wheel 112 and a photoelectric sensor 113b for detecting rotation of the code disc 113a, so that the code disc 113a is driven to rotate when the ranging wheel 112 rolls, the angle through which the code disc 113a rotates is obtained by the photoelectric sensor 113b, and then the position information of the detection device 100 in a drill hole can be obtained by calculating and obtaining the rolling distance of the roller corresponding to the hole wall when the code disc 113a rotates.

The grating encoder 113 further comprises a processor 113c electrically connected with the photoelectric sensor 113b, so that when the ranging wheel 112 rolls, the battery 104 is used for supplying power to the grating encoder 113, the photoelectric sensor 113b is enabled to collect the angle rotated by the encoder, an electric signal is sent to the processor 113c, and the rolling distance of the roller can be obtained through calculation by the processor 113c according to the electric signal, so that position information can be obtained.

The grating encoder 113 measures the distance the ranging wheel 112 rolls using a grating ranging technique. The present application does not constitute a substantial improvement to the principle of the grating ranging technique, and the principle is not described in detail herein. However, when the grating encoder 113 works, the external light environment interferes with the accuracy of ranging, so that the photoelectric sensor 113 is disposed inside the housing 103, so as to reduce the interference of the external environment light and the like on the ranging result.

Correspondingly, the housing 103 further comprises: an inter-shell support 114. The inter-housing support 114 is used to mount the ranging wheel 112 and the grating encoder 113.

For example, referring to fig. 13 and 14, a sliding groove 114a is provided on the inter-shell support 114, and a sliding block 114b is slidably provided in the sliding groove 114a of the inter-shell support 114. Ranging wheel 112 is rotatably coupled to slider 114b and ranging wheel 112 extends at least partially out of chute 114a to enable ranging wheel 112 to contact the borehole wall. Code wheel 113a is rotatably disposed within slider 114b and is coupled to ranging wheel 112 by a belt drive or other means of transmission. The photoelectric sensor 113b is fixedly arranged inside the slider 114b and is electrically connected with the circuit board 105 and the battery 104. Processor 113c may be disposed inside slider 114b or soldered to circuit board 105. A plurality of supporting springs 114c are arranged between the sliding block 114b and the groove wall of the sliding groove 114a, so that the supporting springs 114c provide elastic force for the sliding block 114b, and the distance measuring wheel 112 keeps contact with the wall of the drilling hole to roll during the movement of the detecting device 100 in the drilling hole. At this time, the position information of the detecting device 100 can be obtained during the rolling process of the roller.

An inter-housing mount 114 is located between the mounting interface and the third pod 103f, preferably the inter-housing mount 114 is disposed between the second pod 103d and the third pod 103f such that the ranging wheel 112 is relatively closer to the probe 101 when the ranging wheel 112 contacts the borehole wall at a distance closer to the depth within the borehole at which the probe 101 is to collect probe data.

The inter-housing bracket 114 is disposed between the second housing 103d and the third housing 103f to form a hollowed-out space 114d between the second housing 103d and the third housing 103f for accommodating the ranging wheel 112. The arrangement of the hollowed-out space 114d enables impurities such as broken stone in a drilled hole to pass through, so that the accumulation of the impurities at the support 114 between the shells is reduced, the possibility that the ranging wheel 112 is blocked by the impurities is reduced, and the ranging wheel 112 is further moved smoothly.

On the basis of the provision of the hollowed-out space 114d, unlike the case where the slider 114b is provided on the inter-case support 114 to mount the ranging wheel 112, the following specific possible embodiment may be adopted to mount the roller to the inter-case support 114.

Referring to fig. 15 and 16, the probing apparatus 100 further includes: supporting the swing arm 115 and the elastic member. Wherein, the two ends of the supporting swing arm 115 are respectively connected with the distance measuring wheel 112 and the shell-to-shell bracket 114 in a rotating way. An elastic member is provided between the support swing arm 115 and the inter-shell bracket 114 to bias the support swing arm 115 to move to a preset position with respect to the inter-shell bracket. The support swing arm 115 is at least partially accommodated in the hollowed-out space 114d. The elastic member may be configured as a torsion spring 116 disposed between the support swing arm 115 and the inter-housing bracket 114. That is, the roller contacts the borehole wall and swings, the torsion spring 116 applies an elastic force to the roller, so that the roller has a tendency to swing to a predetermined position with respect to the inter-housing bracket 114. Specifically, when the roller is in the predetermined position, it is at least partially positioned outside of the inter-housing support 114 so that the roller contacts the borehole wall. Thus, the roller can be kept in contact with the wall of the borehole.

Correspondingly, the code plate 113a is rotatably disposed inside the inter-shell support 114 and is linked with the ranging wheel 112 by belt transmission or other transmission modes, and the rotation center of the code plate 113a coincides with the rotation center of the support swing arm 115 relative to the inter-shell support 114. The photoelectric sensor 113b is fixedly disposed inside the inter-housing bracket 114 and electrically connected to the circuit board 105 and the battery 104.

When the inter-shell holder 114 is provided, both ends of the inter-shell holder 114 may be connected to the second and third cases 103d and 103f, respectively, by means of a detachable fixed connection such as a screw connection. At this time, the first terminal 106 or the second terminal 107 is provided at both ends of the inter-case support 114, respectively, and the wire groove 114e may be provided inside the inter-case support 114 to electrically connect the first terminal 106 or the second terminal 107 at both ends of the support through a cable. And a second terminal 107 or a first terminal 106 is disposed at one end of the second housing 103d and the third housing 103f corresponding to the connection housing bracket 114, so as to electrically connect the battery 104, the circuit board 105, the grating encoder 113, the probe 101, and other components.

With the above arrangement, the components for acquiring the position information can be installed as needed, or the second housing 103d and the third housing 103f can be directly connected to acquire the detection data separately.

According to the technical scheme of the embodiment, the provided detection device 100 can call detection data after detection is finished, and an offline borehole internal information detection mode different from an online detection mode of the related art is realized. The method can acquire different types of detection data and position information corresponding to the detection data according to the needs, and can be flexibly applied to various different construction sites.

Optionally, a centralizer 117 may be fixedly disposed on the outside of the third casing 103f, where the centralizer 117 is made of rubber, hard plastic, or other materials, and the centralizer 117 may contact the borehole wall during the movement of the detecting device 100 in the borehole, so as to reduce the shake when the detecting device 100 moves, so that the collected detection data is more practical, for example, the camera 101b moves relatively smoothly, so that the photographed image is relatively clear.

On this basis, a centralizer 117 may be fixedly installed outside the end of the probe apparatus 100 where the installation interface is provided, so that the probe apparatus 100 can move more stably.
