Technical Field

[0001] The present application relates to the technical field of cameras, and in particular to an intrinsically safe thermal imaging camera for mining. Background Art

[0002] Thermal imaging cameras for mines can display temperature distribution images that are difficult to capture underground in the form of thermal images, which is of great significance for underground safety monitoring.

[0003] A Chinese patent with publication number CN219159963U discloses a mine-use intrinsically safe thermal imaging camera, which includes a camera and an angle adjustment structure. The camera is hingedly arranged, and the angle adjustment structure includes a connecting rod hinged to the camera, a slider hinged to the connecting rod, and a T-shaped slide rail slidably connected to the slider. The shooting angle of the camera can be adjusted by sliding the slider and the T-shaped slide rail relative to each other.

[0004] In the above scheme, the angle adjustment of the camera can only adjust the distance of the shooting picture, which makes it difficult for the camera to shoot the surrounding pictures at the same shooting distance, thereby limiting the monitoring range of the camera. Summary of the invention

[0005] In order to expand the monitoring range of the camera, the present application provides a mining intrinsically safe thermal imaging camera.

[0006] The present application provides a mine-use intrinsically safe thermal imaging camera, which adopts the following technical solution:

[0007] A mine-use intrinsically safe thermal imaging camera comprises a camera body and an adjustment assembly, wherein the adjustment assembly comprises an adjustment part, and the adjustment part comprises an adjustment shell, an adjustment ball, an adjustment wheel and an adjustment rod;

[0008] The adjusting shell is in a hemispherical shell shape and is used to be installed on the well wall. The adjusting ball is located on the opening side of the adjusting shell. The center of the adjusting ball coincides with the center of the adjusting shell. The side of the adjusting ball away from the adjusting shell is fixedly connected to the camera body.

[0009] There are four adjusting wheels, all of which are located on the side of the adjusting ball close to the adjusting shell. The four adjusting wheels are evenly arranged around the diameter direction of the adjusting ball. The adjusting wheels are rotatably connected to the inner wall of the adjusting shell, and a motor is installed at the end. The rotation axes of the four adjusting wheels are parallel to the opening side of the adjusting shell.

[0010] One end of the adjusting rod is fixedly connected to the adjusting ball, and the other end is fixedly connected to a spherical adjusting slide. The adjusting slide is slidably arranged in an adjusting slot provided on the inner wall of the adjusting shell. The adjusting slot guides the adjusting slide to slide in a vertical plane and in a horizontal plane. The adjusting slide pulls the adjusting rod under the restriction of the adjusting slot to make the adjusting ball press against the adjusting wheel.

[0011] By adopting the above technical scheme, the adjusting slide pulls the adjusting ball against the adjusting wheel, and the adjusting wheel can be driven to rotate by the motor. The four adjusting wheels work together to drive the adjusting ball to rotate. The adjusting slide slides in the adjusting groove as the adjusting ball rotates, so that the adjusting ball can rotate in the vertical plane and the horizontal plane. The adjusting ball drives the camera body to swing, so that the camera body can swing in the vertical plane and the horizontal plane, thereby achieving the purpose of adjusting the shooting angle itself, thereby meeting the needs of being able to shoot pictures at different distances and pictures around the same distance, and expanding the monitoring range of the camera body.

[0012] Optionally, the adjustment groove includes a first adjustment groove and a second adjustment groove, a plurality of second adjustment grooves are provided, and the plurality of second adjustment grooves are all connected to the first adjustment groove, the first adjustment groove is used to guide the adjustment slide plate to slide in a vertical plane, and the second adjustment groove is used to guide the adjustment slide plate to slide in a horizontal plane.

[0013] By adopting the above technical solution, the first adjustment groove guides the adjustment slide to slide in the vertical plane, and the second adjustment groove guides the adjustment slide to slide in the horizontal plane. Through the cooperation between the first adjustment groove and the second adjustment groove, the adjustment slide can slide in the adjustment groove to cooperate with the rotation of the adjustment ball.

[0014] Optionally, the interior of the adjusting ball is a spherical hollow structure and is connected to a first measuring part, the first measuring part includes a measuring ball, the measuring ball is rotatably connected inside the adjusting ball, the rotation axis of the measuring ball is horizontally arranged and parallel to the opening side of the adjusting shell, the center of the measuring ball coincides with the center of the adjusting ball, and the center of gravity of the measuring ball is arranged close to its bottom;

[0015] An infrared displacement sensor is embedded at the bottom of the measuring ball, and a measuring groove is opened on the inner wall of the adjusting ball corresponding to the position of the infrared displacement sensor. When the measuring ball rotates relative to the adjusting ball, the distance between the probe of the infrared displacement sensor and the bottom of the measuring groove changes. The infrared displacement sensor is used to transmit the displacement signal between the bottom of the measuring ball and the bottom of the measuring groove.

[0016] The infrared displacement sensor is electrically connected to a controller, which is electrically connected to all motors. The controller responds to the displacement signal and is used to control the start of all motors. The controller is used to accurately control all motors to drive the adjustment ball to rotate at an angle in a vertical plane based on the displacement signal.

[0017] By adopting the above technical solution, when the camera body is adjusted vertically, the controller controls the motor to start so as to drive the adjusting ball to rotate in the vertical plane. Since the center of gravity of the measuring ball is arranged close to the bottom, the measuring ball is not easy to rotate in the vertical plane. When the adjusting ball rotates, the measuring ball and the adjusting ball will rotate relative to each other, so that the displacement signal measured by the infrared displacement sensor changes. Different displacement signals can correspond to different rotation angles, so that the rotation angle of the adjusting ball in the vertical plane can be monitored. The controller regulates the motor based on the displacement signal so that the rotation angle of the adjusting ball meets the preset angle.

[0018] Optionally, a second measuring part is provided in the second adjusting groove, and the second measuring part includes a pressure sensor. The pressure sensor is provided at one end of the second adjusting groove away from the first adjusting groove. The pressure sensor is connected to a measuring spring. The measuring spring is provided along the second adjusting groove, and is connected to a measuring plate at one end away from the pressure sensor. The measuring plate is slidably provided in the second adjusting groove. Under normal circumstances, the measuring plate is located at the connecting point between the second adjusting groove and the first adjusting groove. The pressure sensor is used to output a pressure signal applied by the measuring spring. The pressure sensor is electrically connected to the controller. The controller responds to the pressure signal and is used to accurately control the rotation angle of all motor-driven adjusting balls in the horizontal plane.

[0019] By adopting the above technical solution, when the camera body is adjusted horizontally, the controller controls the motor to drive the adjusting ball to rotate in the horizontal plane, and the adjusting ball drives the adjusting slide to slide from the first adjusting slot into the second adjusting slot. The adjusting slide is pressed on the measuring plate and pushes the measuring plate to slide. The measuring plate squeezes the measuring spring so that the force applied by the measuring spring on the pressure sensor changes. Different pressure signals can correspond to different rotation angles, so that the rotation angle of the adjusting ball in the horizontal plane can be monitored. The controller regulates the motor based on the pressure signal so that the rotation angle of the adjusting ball meets the preset angle.

[0020] Optionally, the adjustment part further includes an adjustment support plate, which is arranged on the opening side of the adjustment shell, and the adjustment ball is passed through the adjustment support plate and is rotatably connected to the adjustment support plate in any direction.

[0021] By adopting the above technical solution, on the one hand, the adjustment support plate provides support force for the adjustment ball, so that the adjustment ball is more stable when driving the camera body to swing; on the other hand, the adjustment support plate closes the opening side of the adjustment shell, making it difficult for debris and dust underground to enter the adjustment shell and the adjustment slot, thereby making it difficult for foreign objects to be blocked in the adjustment slot.

[0022] Optionally, the adjustment support plate is provided with four display slots on a side away from the adjustment wheel, and the four display slots are evenly arranged around the center of the adjustment ball, wherein two display slots are arranged in the vertical direction, and the remaining two display slots are arranged in the horizontal direction;

[0023] Four display parts are arranged on the adjustment support plate, and the display parts correspond to the display slots one by one. The display parts include a display slide plate, an elastic rope, a pull rope and a scale;

[0024] The display slide plate is slidably arranged in the display slot, and the elastic rope is arranged on a side of the display slide plate away from the adjustment ball, and the elastic rope is used to drive the display slide plate to slide away from the adjustment ball;

[0025] The pull rope is arranged on a side of the display slide plate close to the adjustment ball, the pull rope is connected between the display slide plate and the adjustment ball, and is slidably arranged on the adjustment support plate, and the pull rope just enters the receiving groove provided on the adjustment ball after sliding out of the display groove;

[0026] The scale is located at one side of the display slot and is arranged on the adjustment support plate. The scale is used to display the rotation angle of the adjustment ball.

[0027] By adopting the above technical solution, when the adjusting ball rotates, the adjusting ball pulls the pull rope to slide out of the display slot, and the pull rope pulls the display slide to slide. The position of the display slide opposite to the scale displays the rotation angle of the adjusting ball, and the distribution of the pull rope on the adjusting ball displays the rotation direction of the adjusting ball, so that the rotation angle of the adjusting ball can be directly observed, and the monitoring results of the first measuring part and the second measuring part can be rechecked and verified according to the observed scale value to ensure the accuracy of the angle adjustment of the camera body.

[0028] Optionally, a support assembly is arranged between the camera body and the adjustment shell, the support assembly includes four support telescopic rods, four support telescopic rods are arranged and are all ball-hinged on the opening side of the adjustment shell, the movable ends of the four support telescopic rods are respectively ball-hinged at the four top corners of the end of the camera body, when the motor is started, the support telescopic rods are in a telescopic state, and when the motor is stopped, the support telescopic rods are in a fixed length state.

[0029] By adopting the above technical solution, when the motor drives the adjusting ball to rotate, the supporting telescopic rod cooperates with the camera body to swing in a telescopic state; when the motor stops to stop driving the adjusting ball, the supporting telescopic rod supports the camera body in a fixed state, so that the adjusted state of the camera body can be fixed.

[0030] Optionally, a telescopic hole is provided on the rod body supporting the telescopic rod, the telescopic hole connects the rod cavity and the rodless cavity supporting the telescopic rod, a fluid medium flows through the rod cavity and the rodless cavity supporting the telescopic rod, and a telescopic plate is slidably penetrated on the rod body supporting the telescopic rod, and the telescopic plate is used to close or open the telescopic hole;

The motor and the electromagnet have the same power-on and power-off states. The polarity of the energized electromagnet and the magnetic plate on the side close to each other is the same.

[0032] By adopting the above technical solution, when the motor starts, the electromagnet is also energized, and a magnetic thrust is generated between the energized electromagnet and the magnetic plate. Under the action of the magnetic thrust, the telescopic plate slides out of the telescopic hole to open the telescopic hole, so that the fluid medium can flow between the rod cavity and the rodless cavity supporting the telescopic rod, thereby enabling the supporting telescopic rod to release the fixing effect on the camera body when the motor drives the adjusting ball.

[0033] Optionally, a telescopic spring is provided between the telescopic plate and the rod body supporting the telescopic rod, and the telescopic spring is used to drive the telescopic plate to close the telescopic hole.

[0034] By adopting the above technical solution, after the electromagnet is powered off, the telescopic spring can drive the telescopic plate to slide into the telescopic hole by relying on elastic force to close the telescopic hole, thereby blocking the flow of the fluid medium in the telescopic hole, so that the supporting telescopic rod can exert a fixing effect on the camera body when the motor stops.

DETAILED DESCRIPTION

[0051] The following is combined with Figure 1-8 This application is described in further detail.

[0052] The present application embodiment discloses a mine-use intrinsically safe thermal imaging camera. Figure 1A mine intrinsically safe thermal imaging camera includes a camera body 1, an adjustment component 2 and a support component 3. The camera body 1 is arranged on the adjustment component 2. The adjustment component 2 connects the camera body 1 to the well wall. The adjustment component 2 is used to adjust the shooting direction of the camera body 1 in the vertical plane and the horizontal plane. The support component 3 is arranged between the adjustment component 2 and the camera body 1, and is used to support and fix the camera body 1 after the camera body 1 is adjusted. The adjustment component 2 enables the shooting angle of the camera body 1 to be adjusted horizontally on the basis of far and near adjustment, so that the camera body 1 can not only shoot pictures at different distances, but also shoot pictures around the same distance, thereby expanding the monitoring range of the camera body 1.

[0053] In the present application, the adjustment assembly 2 includes an adjustment portion 21, and the adjustment portion 21 is used to adjust the shooting direction of the camera body 1 in a vertical plane and a horizontal plane.

[0054] Specifically, refer to Figure 1 , Figure 2 and Figure 3 The adjusting portion 21 includes an adjusting shell 211 , an adjusting ball 212 , an adjusting wheel 213 , an adjusting rod 214 and an adjusting support plate 215 .

[0055] Reference Figure 1 and Figure 3 The adjusting shell 211 is in the shape of a hemispherical shell and is vertically arranged. A mounting plate 2114 is fixedly connected to the top of the adjusting shell 211. The mounting plate 2114 is used to be fixed on the well wall so that the adjusting shell 211 can be easily installed on the well wall. The adjusting ball 212 is located on the opening side of the adjusting shell 211. The center of the adjusting ball 212 coincides with the center of the adjusting shell 211. The side of the adjusting ball 212 away from the adjusting shell 211 is fixedly connected to the camera body 1. The camera body 1 can swing along with the adjusting ball 212, so that the shooting direction of the camera body 1 can be adjusted by rotating the adjusting ball 212.

[0056] Reference Figure 2 and Figure 3 There are four adjusting wheels 213, and they are all located on the side of the adjusting ball 212 close to the adjusting shell 211. The four adjusting wheels 213 are evenly arranged around the diameter direction of the adjusting ball 212. The adjusting ball 212 and the adjusting wheel 213 are in a tight state. Both ends of the adjusting wheel 213 are rotatably connected with support plates 2133, and the support plates 2133 are fixedly connected to the inner wall of the adjusting shell 211. The support plates 2133 enable the adjusting wheel 213 to be rotatably connected to the adjusting shell 211. The rotation axes of the four adjusting wheels 213 are parallel to the opening side of the adjusting shell 211. A motor 2131 is provided at the end of the adjusting wheel 213, and the output shaft of the motor 2131 is fixedly connected to the adjusting wheel 213. The motor 2131 is fixedly connected to the support plate 2133, and the motor 2131 can drive the adjusting wheel 213 to rotate forward and reverse.

[0057] From the perspective of facing the opening side of the adjustment housing 211, the four adjustment wheels 213 are numbered clockwise as adjustment wheel 1, adjustment wheel 2, adjustment wheel 3 and adjustment wheel 4. When the adjustment wheel 1 rotates forward, the adjustment wheel 2 rotates forward, the adjustment wheel 3 rotates reversely and the adjustment wheel 4 rotates reversely, the four adjustment wheels 213 jointly drive the adjustment ball 212 to lift the camera body 1 upward; when the adjustment wheel 1 rotates reversely, the adjustment wheel 2 rotates reversely, the adjustment wheel 3 rotates forwardly and the adjustment wheel 4 rotates forwardly, the four adjustment wheels 213 jointly drive the adjustment ball 212 to lift the camera body 1 upward. The camera body 1 swings downward; when the adjusting wheel 1 rotates forward, the adjusting wheel 2 rotates reversely, the adjusting wheel 3 rotates reversely, and the adjusting wheel 4 rotates forward, the four adjusting wheels 213 jointly drive the adjusting ball 212 to make the camera body 1 swing to the left; when the adjusting wheel 1 rotates reversely, the adjusting wheel 2 rotates forward, the adjusting wheel 3 rotates forward, and the adjusting wheel 4 rotates reversely, the four adjusting wheels 213 jointly drive the adjusting ball 212 to make the camera body 1 swing to the right; thereby, under the joint action of the four adjusting wheels 213, the camera body 1 expands the monitoring range.

[0058] Further, refer to Figure 3 A rubber layer 2123 is fixed on the outer surface of the adjusting ball 212, and a plurality of anti-skid ridges 2132 are fixed on the side wall of the adjusting wheel 213 along the circumferential direction. The anti-skid ridges 2132 are squeezed on the rubber layer 2123 to increase the friction between the adjusting wheel 213 and the adjusting ball 212, so that the adjusting wheel 213 is not prone to slipping when driving the adjusting ball 212.

[0059] One end of the adjusting rod 214 is fixedly connected to the adjusting ball 212, and the other end is fixedly connected to a spherical adjusting slide 2141. The adjusting slide 2141 is slidably set in an adjusting groove 2111 opened on the inner wall of the adjusting shell 211. The adjusting groove 2111 includes a first adjusting groove 2112 and a second adjusting groove 2113. A plurality of second adjusting grooves 2113 are opened, and the plurality of second adjusting grooves 2113 are symmetrically distributed on both sides of the first adjusting groove 2112. The plurality of second adjusting grooves 2113 are all connected to the first adjusting groove 2112. The first adjusting groove 2112 is used to guide the adjusting slide 2141 to slide in a vertical plane, and the second adjusting groove 2113 is used to guide the adjusting slide 2141 to slide in a horizontal plane.

[0060] Under the restriction of the adjusting slot 2111, the adjusting slide 2141 pulls the adjusting rod 214 to make the adjusting ball 212 press against the adjusting wheel 213, thereby realizing the pressing state between the adjusting ball 212 and the adjusting wheel 213, and making the pressing state between the adjusting ball 212 and the adjusting wheel 213 stable and reliable. When the adjusting wheel 213 drives the adjusting ball 212 to rotate, the adjusting rod 214 drives the adjusting slide 2141 to slide in the adjusting slot 2111, and the adjusting slide 2141 makes the driving force of the adjusting wheel 213 on the adjusting ball 212 stable and reliable.

[0061] Reference Figure 1 and Figure 3 The adjusting support plate 215 is fixedly connected to the opening side of the adjusting shell 211, and the adjusting ball 212 is penetrated by the adjusting support plate 215 and is connected to the adjusting support plate 215 for rotation in any direction. The center of the adjusting ball 212 is located on the plane where the adjusting support plate 215 is located. On the one hand, the adjusting support plate 215 provides supporting force for the adjusting ball 212, so that the adjusting ball 212 is more stable when driving the camera body 1 to swing. On the other hand, the adjusting support plate 215 closes the opening side of the adjusting shell 211, so that the debris and dust in the well are not easy to enter the adjusting shell 211 and the adjusting slot 2111, so that the adjusting slot 2111 is not easy to be blocked by foreign objects.

[0062] When adjusting the shooting angle of the camera body 1, the adjusting slide 2141 pulls the adjusting ball 212 against the adjusting wheel 213, the motor 2131 drives the adjusting wheel 213 to rotate, and the four adjusting wheels 213 work together to drive the adjusting ball 212 to rotate. The adjusting slide 2141 slides in the adjusting slot 2111 as the adjusting ball 212 rotates, and the adjusting ball 212 drives the camera body 1 to swing, so that the camera body 1 can swing in the vertical plane and the horizontal plane to adjust its own shooting angle, thereby meeting the demand for shooting pictures at different distances and pictures around the same distance, thereby expanding the monitoring range of the camera body.

[0063] Further, refer to Figure 3 The adjustment component 2 also includes a first measuring part 22 and a second measuring part 23. The first measuring part 22 is used to control the adjustment accuracy of the adjustment ball 212 in the vertical plane, and the second measuring part 23 is used to control the adjustment accuracy of the adjustment ball 212 in the horizontal plane.

[0064] Reference Figure 1 and Figure 3 The first measuring part 22 includes a measuring ball 221, an infrared displacement sensor 222 and a controller 223. The interior of the adjusting ball 212 is a spherical hollow structure. The measuring ball 221 is rotatably connected inside the adjusting ball 212. The rotation axis of the measuring ball 221 is horizontally arranged and parallel to the opening side of the adjusting shell 211. The center of the measuring ball 221 coincides with the center of the adjusting ball 212, and the center of gravity of the measuring ball 221 is arranged close to its bottom.

[0065] Specifically, refer to Figure 4 Both ends of the rotation axis of the measuring ball 221 are fixedly connected with a rotating block 2211, and the rotating block 2211 is adapted to be rotatable in a rotating groove 2124 opened on the inner wall of the adjusting ball 212. The rotating block 2211 and the rotating groove 2124 form a rotating connection structure between the measuring ball 221 and the adjusting ball 212.

[0066] Reference Figure 3 The infrared displacement sensor 222 is embedded in the bottom end of the measuring ball 221 and is fixedly connected to the measuring ball 221. A rectangular measuring groove 2121 is opened on the inner wall of the adjusting ball 212 corresponding to the position of the infrared displacement sensor 222. The bottom of the measuring groove 2121 is tangent to the inner wall of the adjusting ball 212. When the camera body 1 is in a horizontal position, the probe of the infrared displacement sensor 222 is directly opposite to the position where the bottom of the measuring groove 2121 is tangent to the inner wall of the adjusting ball 212. When the measuring ball 221 rotates relative to the adjusting ball 212, the distance between the probe of the infrared displacement sensor 222 and the bottom of the measuring groove 2121 changes. The infrared displacement sensor 222 is used to transmit a displacement signal between the bottom end of the measuring ball 221 and the bottom of the measuring groove 2121.

[0067] Reference Figure 1 and Figure 3 The controller 223 is fixed on the mounting plate 2114. The controller 223 is electrically connected to the infrared displacement sensor 222 and all the motors 2131. The controller 223 responds to the displacement signal. The controller 223 is used to control the start of all the motors 2131. The controller 223 is used to accurately control all the motors 2131 to drive the adjustment ball 212 to rotate in the vertical plane based on the displacement signal.

[0068] When the camera body 1 is adjusted vertically, the controller 223 controls the motor 2131 to start, so as to drive the adjusting ball 212 to rotate in the vertical plane. Since the center of gravity of the measuring ball 221 is arranged close to the bottom, the measuring ball 221 is not easy to rotate in the vertical plane. When the adjusting ball 212 rotates, the measuring ball 221 and the adjusting ball 212 will rotate relative to each other, so that the displacement signal measured by the infrared displacement sensor 222 changes. Different displacement signals can correspond to different rotation angles, so that the rotation angle of the adjusting ball 212 in the vertical plane can be monitored. The controller 223 regulates the motor 2131 based on the displacement signal, so that the rotation angle of the adjusting ball 212 meets the preset angle.

[0069] Reference Figure 3 and Figure 5, there are multiple second measuring parts 23, and they are respectively located in the second adjusting groove 2113. The second measuring part 23 includes a pressure sensor 231, a measuring spring 232 and a measuring plate 233. The pressure sensor 231 is fixed at one end of the second adjusting groove 2113 away from the first adjusting groove 2112; the measuring spring 232 is arranged along the second adjusting groove 2113, and one end of the measuring spring 232 close to the pressure sensor 231 is fixedly connected to the pressure sensor 231; the measuring plate 233 is slidably arranged in the second adjusting groove 2113, and the measuring plate 233 is fixedly connected to one end of the measuring spring 232 away from the pressure sensor 231. Under normal conditions, the measuring plate 233 is located at the connection between the second adjusting groove 2113 and the first adjusting groove 2112; the pressure sensor 231 is used to output the pressure signal applied by the measuring spring 232, the pressure sensor 231 is electrically connected to the controller 223, the controller 223 responds to the pressure signal, and is used to accurately control the angle of rotation of the adjusting ball 212 driven by all motors 2131 in the horizontal plane.

[0070] When the camera body 1 is adjusted horizontally, the controller 223 controls the motor 2131 to drive the adjusting ball 212 to rotate in the horizontal plane. The adjusting ball 212 drives the adjusting slide 2141 to slide from the first adjusting groove 2112 into the second adjusting groove 2113. The adjusting slide 2141 is pressed on the measuring plate 233 and pushes the measuring plate 233 to slide. The measuring plate 233 squeezes the measuring spring 232 so that the force applied by the measuring spring 232 to the pressure sensor 231 changes. Different pressure signals can correspond to different rotation angles, so that the rotation angle of the adjusting ball 212 in the horizontal plane can be monitored. The controller 223 regulates the motor 2131 based on the pressure signal so that the rotation angle of the adjusting ball 212 meets the preset angle.

[0071] Furthermore, refer to Figure 1 and Figure 3 , four display slots 2151 are provided on one side of the adjustment support plate 215 away from the adjustment wheel 213, and the four display slots 2151 are evenly arranged around the center of the adjustment ball 212, wherein two display slots 2151 are arranged in the vertical direction, and the remaining two display slots 2151 are arranged in the horizontal direction. The adjustment component 2 also includes a display unit 24, and the display unit 24 is provided with four, and one-to-one corresponds to the display slots 2151, and the display unit 24 is used to display the angle value adjusted by the adjustment ball 212, wherein the two display slots 2151 in the vertical direction are used to cooperate with the display unit 24 to display the rotation angle of the adjustment ball 212 in the vertical plane, and the two display slots 2151 in the horizontal direction are used to cooperate with the display unit 24 to display the rotation angle of the adjustment ball 212 in the horizontal plane.

[0072] Reference Figure 6 The display unit 24 includes a display slide 241 , an elastic rope 242 , a pull rope 243 and a scale 244 .

[0073] Reference Figure 3 and Figure 6 The display slide 241 is slidably disposed in the display slot 2151, one end of the elastic rope 242 is fixedly connected to the side of the display slide 241 away from the adjusting ball 212, and the other end of the elastic rope 242 is fixedly connected to the side wall of the display slot 2151 opposite to the display slide 241. The elastic rope 242 is used to drive the display slide 241 to slide away from the adjusting ball 212. After the display slide 241 slides close to the adjusting ball 212, the elastic rope 242 can rely on the elastic force to drive the display slide 241 to reset.

[0074] Reference Figure 1 , Figure 3 and Figure 6 The pull rope 243 is located on a side of the display slide 241 close to the adjusting ball 212. The pull rope 243 is fixedly connected between the display slide 241 and the adjusting ball 212. The pull rope 243 is slidably passed through the adjusting support plate 215. When the adjusting ball 212 rotates, the adjusting ball 212 pulls the pull rope 243 to slide, and the pull rope 243 pulls the display slide 241 to slide, so that the rotation angle of the adjusting ball 212 can be displayed by the position of the display slide 241 after sliding.

[0075] Reference Figure 3 and Figure 6 The scale 244 is located at one side of the display slot 2151 and is arranged on the adjustment support plate 215. The scale 244 is used to display the rotation angle of the adjustment ball 212. By displaying the specific position of the scale 244 corresponding to the slide plate 241, the rotation angle of the adjustment ball 212 can be clearly known, so that the rotation angle of the adjustment ball 212 is easy to observe intuitively, and the monitoring results of the first measuring part 22 and the second measuring part 23 can be rechecked and verified according to the observed scale value.

[0076] A receiving groove 2122 for receiving the pull rope 243 is provided on the adjusting ball 212 relative to each pull rope 243. After the pull rope 243 slides out of the display groove 2151, the pull rope 243 can just enter the receiving groove 2122, so that the sliding of the pull rope 243 is not easy to interfere with the relative rotation between the adjusting ball 212 and the adjusting support plate 215.

[0077] When the adjusting ball 212 rotates, the adjusting ball 212 pulls the pull rope 243 to slide out of the display slot 2151, and the pull rope 243 pulls the display slide 241 to slide. The position where the display slide 241 and the scale 244 are opposite to each other displays the rotation angle of the adjusting ball 212. The distribution of the pull rope 243 on the adjusting ball 212 displays the rotation direction of the adjusting ball 212, so that the rotation angle of the adjusting ball 212 can be directly observed, and the monitoring results of the first measuring part 22 and the second measuring part 23 can be rechecked and verified according to the observed scale values ​​to ensure the accuracy of the angle adjustment of the camera body 1.

[0078] In this application, reference is made to Figure 1 and Figure 3 The supporting assembly 3 includes a supporting telescopic rod 31.

[0079] Four supporting telescopic rods 31 are provided, and all of them are ball-hinged on the opening side of the adjusting shell 211. The movable ends of the four supporting telescopic rods 31 are correspondingly hinged at the four vertex corners of the end of the camera body 1. When the motor 2131 is started, the supporting telescopic rod 31 is in a telescopic state. When the motor 2131 is stopped, the supporting telescopic rod 31 is in a fixed length state. When the motor 2131 drives the adjusting ball 212 to rotate, the supporting telescopic rod 31 swings in the telescopic state in coordination with the camera body 1. When the motor 2131 is stopped to stop driving the adjusting ball 212, the supporting telescopic rod 31 supports the camera body 1 in a fixed state, so that the adjusted state of the camera body 1 can be fixed.

[0080] Further, refer to Figure 7 and Figure 8 The support assembly 3 also includes a telescopic plate 32.

[0081] A telescopic hole 311 is provided on the rod body of the supporting telescopic rod 31, and the telescopic hole 311 connects the rod cavity and the rodless cavity of the supporting telescopic rod 31. The rod cavity and the rodless cavity of the supporting telescopic rod 31 flow with a fluid medium through the telescopic hole 311. The fluid medium can be air or hydraulic oil. In the present application, the fluid medium is hydraulic oil. The hydraulic oil flows between the rod cavity and the rodless cavity of the supporting telescopic rod 31 through the telescopic hole 311, so that the supporting telescopic rod 31 can be extended and retracted.

[0082] The telescopic plate 32 is slidably arranged on the rod body supporting the telescopic rod 31, and one end of the telescopic plate 32 is slidably inserted into the telescopic hole 311. The telescopic plate 32 is used to close or open the telescopic hole 311. When the telescopic plate 32 closes the telescopic hole 311, the telescopic plate 32 can block the flow of hydraulic oil in the telescopic hole 311, so that the supporting telescopic rod 31 is in a fixed length state.

[0083] Furthermore, refer to Figure 3 and Figure 8The end of the telescopic plate 32 outside the telescopic hole 311 is fixedly connected with a magnetic plate 33, the magnetic plate 33 is located on one side of the telescopic plate 32, and an electromagnet 34 is arranged opposite to the magnetic plate 33. The electromagnet 34 is arranged on the rod body supporting the telescopic rod 31. The electromagnet 34 corresponds to the motor 2131 one by one. The motor 2131 and the electromagnet 34 have the same power-on and power-off states. The polarity of the electromagnet 34 and the magnetic plate 33 that are close to each other when powered on is the same. The end of the telescopic plate 32 located in the telescopic hole 311 is fixedly connected with a limit plate 321. When the motor 2131 is started, the electromagnet 34 is also energized, and a magnetic thrust is generated between the energized electromagnet 34 and the magnetic plate 33. Under the action of the magnetic thrust, the telescopic plate 32 slides out of the telescopic hole 311 to open the telescopic hole 311, so that the hydraulic oil can flow between the rod cavity and the rodless cavity supporting the telescopic rod 31. The limit plate 321 restricts the telescopic plate 32 from completely slipping out of the telescopic hole 311, so that the telescopic plate 32 is not easy to slide off under the action of the magnetic thrust, so that the supporting telescopic rod 31 can release the fixing effect on the camera body 1 when the motor 2131 drives the adjusting ball 212.

[0084] In addition, a telescopic spring 35 is provided on the side of the telescopic plate 32 away from the magnetic plate 33, one end of the telescopic spring 35 is fixedly connected to the telescopic plate 32, and the other end is fixedly connected to the rod body supporting the telescopic rod 31. The telescopic spring 35 is arranged along the sliding direction of the telescopic plate 32, and the telescopic spring 35 is used to drive the telescopic plate 32 to close the telescopic hole 311. After the electromagnet 34 is powered off, the telescopic spring 35 can drive the telescopic plate 32 to slide into the telescopic hole 311 by relying on elastic force to close the telescopic hole 311, thereby blocking the flow of hydraulic oil in the telescopic hole 311, so that the supporting telescopic rod 31 can exert a fixing effect on the camera body 1 when the motor 2131 stops.

[0085] When the camera body 1 is adjusted, the electromagnet 34 drives the telescopic plate 32 to open the telescopic hole 311, thereby releasing the fixation of the supporting telescopic rod 31 to the camera body 1; after the camera body 1 is adjusted, the telescopic spring 35 drives the telescopic plate 32 to close the telescopic hole 311, thereby allowing the supporting telescopic rod 31 to fix the camera body 1.

[0086] The implementation principle of the intrinsically safe thermal imaging camera for mining in the embodiment of the present application is as follows: when in use, the motor 2131 is started, and the motor 2131 drives the adjustment ball 212 to rotate, while the supporting telescopic rod 31 releases the fixation of the camera body 1, so that the camera body 1 can be swung and adjusted in the vertical plane and the horizontal plane to adjust the shooting angle of the camera body 1, thereby meeting the demand for shooting pictures at different distances and pictures around the same distance, and expanding the monitoring range of the camera body.

[0087] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
