Description

Technical Field

[0001] This utility model belongs to the field of detector technology, specifically relating to a transmission mechanism for a detector. Background Technology

[0002] A sound detector is an instrument used to measure water depth. Its working principle is mainly based on the propagation characteristics of sound waves in water. The sound detector emits sound wave pulses into the water through a transducer. The sound waves propagate in the water and are reflected back after encountering the interface between different media such as the bottom of the water. The transducer then receives the reflected sound wave signal. Based on the time it takes for the sound wave to travel from emission to reception, combined with the speed of sound propagation in water, the water depth can be calculated.

[0003] Because the sensor is simply installed at the bow of the ship, factors such as the ship's own vibration, swaying, and water current impact can easily interfere with the transmission and reception of sound waves. During the ship's navigation, the continuous mechanical vibration generated by the engine and propeller can be transmitted to the sensor through the hull structure, making it impossible for the sensor to stably transmit and receive sound waves, resulting in distortion, attenuation, or even loss of the sound signal. At the same time, with the sensor fixed at the bow, the disassembly and assembly operations are extremely cumbersome when maintenance, replacement, or upgrades are required. Furthermore, the sensor's fixed position and angle at the bow cannot flexibly adapt to different operating environments. This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0025] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-4 The present invention provides a technical solution: a transmission mechanism for a detector, including a frame 1, a lifting assembly 2 installed on one side surface of the frame 1, the lifting assembly 2 including two sets of mounting plates 201 fixedly installed on the upper end of the frame 1, a rotating shaft 203 mounted between the two sets of mounting plates 201, a motor 202 fixedly installed on the outward side of one set of mounting plates 201, and the output end of the motor 202 and the end of the rotating shaft 203 that passes through the mounting plate 201 are fixedly connected by a coupling;

[0027] When the motor 202 starts, it can drive the rotating shaft 203 to rotate. The surface of the rotating shaft 203 is fixedly connected to the middle of the two sets of first bevel gears 204. The first bevel gears 204 rotate synchronously with the rotating shaft 203.

[0028] refer to Figure 3 The front surface of the frame 1 is fixedly installed with slide rails 205 on both sides, and sliders 206 are slidably installed on the surface of the slide rails 205. The bottom bearing of the frame 1 is connected to a lead screw 207, and the surface of the lead screw 207 is threadedly connected to a movable sleeve 209. The surface of the adjacent slider 206 is fixedly connected to one side of the movable sleeve 209.

[0029] When the motor 202 is started, the output end of the motor 202 will drive the rotating shaft 203, which is fixedly connected to it through a coupling, to rotate. Since the rotating shaft 203 is installed between two sets of mounting plates 201 through bearings, and the motor 202 is fixedly installed on the outward side of one set of mounting plates 201, the rotating shaft 203 can rotate smoothly under the drive of the motor 202. As the rotating shaft 203 rotates, the two sets of first bevel gears 204 fixedly installed on it will rotate synchronously according to the rotation of the rotating shaft 203. When the lead screw 207 starts to rotate under the drive of the first bevel gears 204, due to the thread transmission characteristics between the lead screw 207 and the movable sleeve 209, the movable sleeve 209 will move precisely in a straight line along the axial direction of the lead screw 207 under the rotation drive of the lead screw 207.

[0030] One end of the lead screw 207 near the upper first bevel gear 204 is fixed through the middle of the second bevel gear 208. The second bevel gear 208 and the first bevel gear 204 are meshed and connected. The second bevel gear 208 rotates synchronously with the rotation of the first bevel gear 204, so as to drive the lead screw 207 to rotate, causing the slider 206 to move along the slide rail 205.

[0031] A hand crank is fixedly installed on the rotating shaft 203, which can drive the rotating shaft 203 to rotate.

[0032] Two sets of auxiliary plates 210 are fixedly installed on the opposite side surfaces of the two sets of sliders 206, and a support plate 4 is fixedly connected between the two sets of auxiliary plates 210.

[0033] refer to Figure 2 , Figure 4 A detection component 3 is fixedly connected to the hollow position of the two sets of support plates 4. The middle part of the support plate 4 is hollow. The detection component 3 includes two sets of first mounting columns 301 which are respectively horizontally fixed to the front and rear ends of the hollow position of the support plate 4. The upper surfaces of the two sets of first mounting columns 301 are respectively longitudinally fixedly connected to the upper surface of the second mounting column 302. One set of first mounting columns 301 is fixedly connected to a first fixing seat 308 along the length direction. A first electric telescopic rod 305 is fixedly connected to the front side of the first fixing seat 308. The telescopic end of the first electric telescopic rod 305 is fixedly connected to a second fixing seat 309. The surface of the second fixing seat 309 is fixedly connected to the upper surface of the fixing plate 304.

[0034] The middle part of the fixing plate 304 is installed through the outer wall of the fixed end of the second electric telescopic rod 306. The bottom of the telescopic end of the second electric telescopic rod 306 is fixedly installed with a sensing probe 307. The sensing probe 307 can move up and down within a certain range with the telescopic end of the second electric telescopic rod 306.

[0035] Two sets of opposing sliding blocks are mounted on the bottom surface of the fixed plate 304. Guide rails 303 are slidably mounted on the bottom of the sliding blocks. The bottom of the guide rails 303 is fixedly mounted on the upper surface of the second mounting column 302. When the channel foreign object detection mission is initiated, the motor 202 starts, driving the rotating shaft 203 to rotate. This causes the two sets of first bevel gears 204 fixed on the rotating shaft 203 to rotate synchronously. When the first bevel gears 204 rotate, the second bevel gear 208 at one end of the lead screw 207 meshing with them rotates synchronously, thereby driving the lead screw 207 to rotate. The rotation of the lead screw 207 causes the threaded connection with the lead screw 207 to rotate. The movable sleeve 209 moves, causing the slider 206 to move vertically along the slide rail 205, thus achieving a lifting function. The second electric telescopic rod 306 installed on the fixed plate 304 can drive the sensing probe 307 to move up and down for depth adjustment. At the same time, the sliding block on the bottom surface of the fixed plate 304 slides on the guide rail 303. When the first electric telescopic rod 305 is activated, its telescopic action will push or pull the second fixed seat 309. Since the second fixed seat 309 is connected to the fixed plate 304, and the fixed plate 304 can slide horizontally through the sliding block connected to the guide rail 303, under the action of the first electric telescopic rod 305, the fixed plate 304 will move horizontally along the direction of the guide rail 303, thereby driving the sensing probe 307 installed below the fixed plate 304 to move horizontally, thus realizing the detection of different horizontal positions.

[0036] The detector's transmission mechanism, driven by a motor 202, links gears, lead screws 207, and other components. Combined with the first electric telescopic rod 305, it adjusts the position of the sensing probe 307 in both horizontal and vertical directions to complete detection tasks at different locations. When precise detection of foreign objects at different depths is required, the second electric telescopic rod 306 extends and retracts with extremely high precision according to the precise instructions issued by the control system. The sensing probe 307, firmly fixed at its telescopic end, moves up and down accordingly, accurately positioning itself at the pre-set optimal detection height. The error is controlled within a very small range, ensuring that the sound wave transmission and reception effects are maximized, accurately capturing the sound wave signals reflected back from underwater foreign objects, and providing a reliable basis for foreign object identification.
