Description

Technical Field

[0001] This utility model belongs to the field of blasting warning technology, specifically relating to a laser sensing device for identifying blasting warning range. Background Technology

[0002] When conducting blasting operations in coal mines, safety precautions are crucial to prevent personnel from accidentally entering the blasting area and avoiding accidents. For underground blasting: the warning distance in straight roadways must be ≥100 meters (rock roadways) or ≥75 meters (coal roadways); for surface blasting: the warning radius must be ≥300 meters, with clear signage, and each warning point must have at least two people (one on guard and one supervising). All warning points must maintain uninterrupted communication with the blasting command center.

[0003] A utility model patent with patent authorization announcement number CN212302700U discloses a visual blasting safety warning and monitoring search system. It includes an AR video monitoring device, a drone monitoring device, an infrared thermal imaging monitoring device, and a monitoring command center. The AR video monitoring device includes an AR monitoring PTZ camera, an AR monitoring communication module, an AR monitoring judgment module, and an AR monitoring storage module. The drone monitoring device includes a drone, a drone control module, a drone communication module, and a drone storage module. The infrared thermal imaging monitoring device includes an infrared thermal imager and an infrared monitoring communication module. The monitoring command center includes a communication module and a display module.

[0004] However, the existing blasting warning management is still relatively extensive, mainly relying on manpower for blasting warning. There are serious blind spots, and it is impossible to accurately determine whether personnel and equipment have been evacuated. Remote assistance from other personnel is required, which increases the labor cost of blasting warning work and leads to low work efficiency. Summary of the Invention

[0005] The purpose of this utility model is to provide a laser sensing device for identifying the blasting warning range, which solves the problem that the existing blasting warning management is still relatively extensive, mainly relying on manpower for blasting warning, with serious blind spots, inaccurate judgment of whether personnel and equipment have been evacuated, requiring remote assistance from other personnel, resulting in increased labor costs and low work efficiency in blasting warning work.

[0006] To achieve the above objectives, this utility model provides a laser sensing device for identifying blast warning ranges, comprising a drone body, four evenly distributed wings on the surface of the drone body, a landing gear at the lower end of the drone body, a laser sensor in contact with the upper rear side of the drone body, a rod fixedly connected to the lower end of the laser sensor, the rod being slidably connected to the drone body, a plate slidably connected to the inner wall of the drone body, the plate being slidably connected to the rod, an end piece in contact with the rear end of the drone body, the end piece being fixedly connected to the plate, and a camera mechanism at the lower end of the drone body.

[0007] The principle of this utility model is as follows: by pushing the laser sensor into contact with the drone body, the insertion rod is inserted into the drone body. During this process, when the round end of the insertion rod contacts the inclined end of the insertion plate, under the pressure of the force, the insertion plate can be pushed to slide along the inner wall of the drone body, thereby driving the end piece to move, causing the spring to deform, and finally causing the insertion plate to contact the surface of the insertion rod. Under the action of the force, the insertion plate slides along the surface of the insertion rod. When the insertion plate slides into the slot on the surface of the insertion rod, the spring returns to its original deformation, thereby pulling the insertion plate to insert into the insertion rod, limiting the insertion rod, and making the insertion rod drive the laser sensor to be in a stable position. The high-definition camera can be used to monitor blasting areas. When the electromagnet magnetically attracts the disk, the lever can be pulled to move, causing the guide plate to slide along the inner wall of the mounting bracket. This causes the second spring to deform, ultimately disengaging the lever from the locking hole and no longer restraining the rotating column. When the motor drives the output shaft to rotate, it can rotate the high-definition camera and adjust its position. When the high-definition camera deflects to the corresponding position, the electromagnet is turned off, and the magnetic attraction to the disk is no longer used. The second spring returns to its original deformation, pushing the lever to insert into the next locking hole and limiting the rotating column, thus stabilizing the high-definition camera and preventing centrifugal deviation.

[0008] The beneficial effects of this utility model are as follows: This solution pushes the laser sensor into contact with the drone body, allowing the insertion rod to be inserted into the drone body. Under the pressure of the round end of the insertion rod, the insertion plate can slide along the surface of the insertion rod. With the deformation of the spring, the insertion plate can limit the insertion of the insertion rod, thereby ensuring the laser sensor is stably positioned. With the help of the laser sensor and the ground early warning management platform, it can identify and use unauthorized personnel. Through the setting of the high-definition camera, it can automatically capture and delineate the explosion warning range. Driven by the motor, the high-definition camera can be deflected to improve the monitoring range. With the cooperation of components such as the card hole, the card rod, and the electromagnet, the high-definition camera can be assisted in limiting its position to ensure the accuracy of the high-definition camera's position and avoid the problem of centrifugal deviation of the high-definition camera.

[0009] Furthermore, the landing gear is provided in two parts, which are symmetrically distributed on the UAV body. The landing gear configuration ensures the normal take-off and landing of the UAV body.

[0010] Furthermore, a spring is provided on the outer side of the insert plate. One end of the spring is welded to the end piece, and the other end of the spring is welded to the drone body. The end piece can be connected and used through the provision of the spring.

[0011] Furthermore, the camera mechanism includes a mounting frame. The mounting frame is fixedly connected to the lower middle part of the UAV body. A motor is fixedly mounted on the left end of the mounting frame. The output shaft of the motor is rotatably connected to the mounting frame. A high-definition camera is fixedly mounted on the output shaft of the motor. A rotating column is rotatably connected to the inner wall of the mounting frame. The rotating column is fixedly connected to the high-definition camera. A locking hole is opened on the surface of the rotating column. A mounting plate is fixedly connected to the lower right end of the mounting frame. An electromagnet is fixedly mounted on the right end of the mounting plate. A guide plate is slidably connected to the inner wall of the mounting frame. A locking rod is fixedly connected to the right end of the guide plate. The locking rod is slidably connected to the locking hole. Through the driving action of the motor, the monitoring angle of the high-definition camera can be adjusted. Under the action of the locking hole, locking rod and other structures, the rotating column can be limited, thereby positioning the high-definition camera to ensure its stability.

[0012] Furthermore, multiple locking holes are provided, and these holes are arranged in a circular array on the rotating column. The locking holes facilitate engagement with the locking rod.

[0013] Furthermore, a second spring is welded to the lower end of the guide plate, and the other end of the second spring is welded to the mounting plate. The guide plate can be connected and used through the setting of the second spring.

[0014] Furthermore, a disk is fixedly connected to the lower end of the lever, and the disk is located above the electromagnet. The disk facilitates magnetic attraction when used with the electromagnet. Attached Figure Description

Detailed Implementation

[0017] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment provides a laser sensing device for identifying blast warning range, including a drone body 1. The surface of the drone body 1 is provided with four evenly distributed wings 2. The lower end of the drone body 1 is provided with landing gear 3. The upper rear side of the drone body 1 is in contact with a laser sensor 4. The lower end of the laser sensor 4 is fixedly connected to a plug rod 5, which is slidably connected to the drone body 1. The inner wall of the drone body 1 is slidably connected to a plug plate 6, which is slidably connected to the plug rod 5. The rear end of the drone body 1 is in contact with an end piece 7, which is fixedly connected to the plug plate 6.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, there are two landing gears 3, which are symmetrically distributed on the UAV body 1. The landing gears 3 ensure the normal take-off and landing of the UAV body 1. A spring 8 is provided on the outer side of the insert plate 6. One end of the spring 8 is welded to the end piece 7, and the other end of the spring 8 is welded to the UAV body 1. The end piece 7 can be connected and used through the spring 8.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, a camera mechanism 9 is provided at the lower end of the drone body 1. The camera mechanism 9 includes a mounting frame 90. The mounting frame 90 is fixedly connected to the middle of the lower end of the drone body 1. A motor 91 is fixedly mounted on the left end of the mounting frame 90. The output shaft of the motor 91 is rotatably connected to the mounting frame 90. A high-definition camera 92 is fixedly mounted on the output shaft of the motor 91. A rotating column 93 is rotatably connected to the inner wall of the mounting frame 90. The rotating column 93 is fixedly connected to the high-definition camera 92. A locking hole 94 is provided on the surface of the rotating column 93. The right side of the mounting frame 90... A mounting plate 95 is fixedly connected to the lower end of the mounting plate 95, and an electromagnet 96 is fixedly installed on the right end of the mounting plate 95. A guide plate 97 is slidably connected to the inner wall of the mounting bracket 90, and a locking rod 98 is fixedly connected to the right end of the guide plate 97. The locking rod 98 is slidably connected to the locking hole 94. Driven by the motor 91, the monitoring angle of the high-definition camera 92 can be adjusted. Under the action of the locking hole 94, locking rod 98 and other structures, the rotating column 93 can be limited, thereby positioning the high-definition camera 92 to ensure its stability.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, multiple locking holes 94 are provided, arranged in a circular array on the rotating column 93. The locking holes 94 facilitate engagement with the locking rod 98. A second spring 99 is welded to the lower end of the guide plate 97, and the other end of the second spring 99 is welded to the mounting plate 95. The second spring 99 allows the guide plate 97 to be connected. A disk 990 is fixedly connected to the lower end of the locking rod 98. The disk 990 is located above the electromagnet 96. The disk 990 facilitates magnetic attraction with the electromagnet 96.

[0021] The specific implementation process of this utility model is as follows: By pushing the laser sensor 4 into contact with the drone body 1, the insertion rod 5 is inserted into the drone body 1. During this process, when the round end of the insertion rod 5 contacts the inclined end of the insertion plate 6, under the pressure of the force, the insertion plate 6 can be pushed to slide along the inner wall of the drone body 1, so as to drive the end piece 7 to move, causing the spring 8 to deform, and finally the insertion plate 6 to contact the surface of the insertion rod 5. Under the action of the force, the insertion plate 6 slides along the surface of the insertion rod 5. When the insertion plate 6 slides into the slot on the surface of the insertion rod 5, the spring 8 returns to its deformation, so as to pull the insertion plate 6 to insert into the insertion rod 5, limit the insertion rod 5, and make the insertion rod 5 drive the laser sensor 4 to be stable. The high-definition camera 92 can be used to monitor the blasting area. When the electromagnet 96 is activated to magnetically attract the disk 990, the lever 98 can be pulled to move, causing the guide plate 97 to slide along the inner wall of the mounting bracket 90. This causes the second spring 99 to deform, ultimately disengaging the lever 98 from the locking hole 94, thus no longer restricting the rotating column 93. When the motor 91 drives the output shaft to rotate, it can drive the high-definition camera 92 to rotate, adjusting its position. When the high-definition camera 92 deflects to the corresponding position, the electromagnet 96 is turned off, ceasing to magnetically attract the disk 990. The second spring 99 returns to its original deformation, pushing the lever 98 to insert into the next locking hole 94, limiting the rotating column 93 and ensuring the high-definition camera 92 remains stable, preventing centrifugal deviation.

[0022] This solution pushes the laser sensor 4 into contact with the drone body 1, causing the insertion rod 5 to be inserted into the drone body 1. Under the pressure of the round end of the insertion rod 5, the insertion plate 6 can slide along the surface of the insertion rod 5. With the deformation of the spring 8, the insertion plate 6 can limit the insertion of the insertion rod 5, thereby ensuring the laser sensor 4 is stably positioned. With the laser sensor 4 and the ground early warning management platform, it can identify and use unauthorized personnel. Through the setting of the high-definition camera 92, it can automatically capture and delineate the explosion warning range. Driven by the motor 91, the high-definition camera 92 can be deflected to improve the monitoring range. With the cooperation of components such as the card hole 94, the card rod 98, and the electromagnet 96, the high-definition camera 92 can be assisted in limiting its position to ensure the accuracy of the high-definition camera 92's position and avoid the problem of centrifugal deviation of the high-definition camera 92.
