[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0021] Example: See Figure 1-7The utility model provides a technical solution: a connecting rod of an underwater detection device, including a telescopic rod sleeve 1, a telescopic rod 2 and a pulling rod 19. The telescopic rod 2 is movably connected to the telescopic rod sleeve 1 by a slider 12. The telescopic rod 2 is provided with a scale, and the specific length can be known by extending and retracting the telescopic rod 2. One end of the telescopic rod 2 is connected to a connecting rod 3 or a pulling rod 19. When the length between the telescopic rod 2 and the pulling rod 19 is not enough, a connecting rod 3 is added between the telescopic rod 2 and the pulling rod 19, thereby increasing the overall length to adapt to different water depths. The telescopic rod 2, the connecting rod 3 and one end of the pulling rod 19 are all connected to a connecting sleeve 9. The connecting rod 3 is connected to the telescopic rod 2 and the pulling rod 19 through the connecting sleeve 9. The connecting sleeve 9 has the advantages of fast connection speed, firm and stable connection, and is not easy to fall off. A socket 14 is provided inside the connecting sleeve 9, and a spring button limiting threaded through hole 17 is opened on the inner wall of the socket 14. A magnetic column slot 13 is provided on one side of the socket 14. The slot 13 is connected to the jack 14 and the diameter of the jack 14 is larger than the diameter of the magnet column slot 13. The end of the connecting rod 3 and the pull rod 19 away from the connecting sleeve 9 is connected to the magnet column 15 that matches the magnet column slot 13. The circumferential surface of the connecting rod 3 and the pull rod 19 close to the magnet column 15 is installed with a spring button 16; the magnet column 15 at one end of the connecting rod 3 and the pull rod 19 is inserted into the magnet column slot 13 in the connecting sleeve 9 for magnetic positioning, and the inner wall of the magnet column slot 13 is fixed. Magnetic material is also selected for magnetic attraction of the magnetic column 15. The spring button 16 at one end of the connecting rod 3 and the pull rod 19 is squeezed into the socket 14 when the connecting rod 3 and the pull rod 19 are inserted into the socket 14. When the connecting rod 3 and the pull rod 19 are rotated, the spring button 16 will be driven to rotate. When encountering the spring button limiting threaded through hole 17 on the connecting sleeve 9, the spring button 16 enters the spring button limiting threaded through hole 17 under the action of the spring to achieve limitation.

[0022] The telescopic rod sleeve 1, the telescopic rod 2 and the pull rod 19 are all provided with scales, wherein the scales are fluorescent scales, which can automatically display the liquid level for easy reading. The required length can be quickly adjusted through the scales on the telescopic rod sleeve 1, the telescopic rod 2 and the pull rod 19.

[0023] The pull-out rod 19 is also connected to other equipment through the connecting sleeve 9, such as a micro camera, a black and white disk, a water dispenser, a scoop net and other specific experimental tools. When these tools are installed on the connecting sleeve 9 at the end of the pull-out rod 19, they are first connected by magnetic attraction, and then the bolt is passed through the spring button limiting threaded through hole 17 to limit the magnetic column on the tool. The side of the magnetic column on the tool is provided with a threaded countersunk hole that matches the bolt, which facilitates the bolt to enter the threaded countersunk hole to limit the magnetic column, thereby achieving the purpose of double fixation.

[0024] A motor 6 is installed on the end surface of the telescopic rod sleeve 1 away from the telescopic rod 2. The main shaft of the motor 6 is connected to the reduction gear 10 in the telescopic rod sleeve 1. A battery 18 is provided on the outside of the main shaft of the motor 6. A charging port is provided on the telescopic rod sleeve 1, and the charging port is electrically connected to the battery 18. A screw rod 11 is connected to the side of the reduction gear 10 away from the main shaft of the motor 6. The screw rod 11 is connected to the slider 12 through a thread. The forward and reverse rotation of the motor 6 drives the gear in the reduction gear 10 to rotate, and the rotation of the gear drives the forward and reverse rotation of the screw rod 11, so that the slider 12 on the telescopic rod 2 moves back and forth in the telescopic rod sleeve 1, thereby realizing the forward and backward extension of the telescopic rod 2.

[0025] The diameter of the spring button limiting threaded through hole 17 is larger than the diameter of the spring button 16. When other products are connected to the end of the connecting rod 3, the connected products can be further fixed by passing bolts through the spring button limiting threaded through hole 17 to prevent them from falling off.

[0026] The reduction gear box 10 is installed inside the telescopic rod sleeve 1 by bolts, and the motor 6 is installed on the end surface of the telescopic rod sleeve 1 by bolts. The main shaft of the motor 6 is connected to the gear inside the reduction gear box 10, and one end of the screw rod 11 is connected to the gear inside the reduction gear box 10. The motor 6 drives the gear of the reduction gear box 10 to rotate, thereby driving the screw rod 11 to rotate.

[0027] A rubber sleeve 4 is fixedly mounted on the telescopic rod sleeve 1 , and a finger ring 5 is connected to the rubber sleeve 4 for the operator to hold the telescopic rod sleeve 1 firmly.

[0028] A speed control switch button 7 is also installed on the telescopic rod sleeve 1. The speed control switch button 7 is electrically connected to the motor 6. The speed control switch button 7 is set on the frequency converter. By controlling the speed of the motor 6, the speed control switch button 7 is electrically connected to the external power supply.

[0029] The telescopic rod sleeve 1 is also provided with a connecting screw 8 , which is used to connect to a tripod to facilitate auxiliary fixation of the telescopic rod sleeve 1 .

[0030] Working principle: A device connecting rod for underwater detection. When in use, the fingers pass through the finger ring buckle 5 and hold the rubber sleeve 4, or the entire telescopic rod sleeve 1 is fixed to the tripod through the connecting screw 8, and then the tripod is fixed to the ship. The speed switch button 7 and the internal frequency converter and controller control the motor 6 to work at the set speed, and then the gear transmission in the reduction box 10 drives the screw rod 11 to rotate. When the motor 6 rotates forward, the screw rod 11 rotates forward. When the motor 6 rotates reversely, the screw rod 11 rotates reversely. The forward or reverse rotation of the screw rod 11 will drive the slider 12 to rotate forward or reverse in the telescopic rod sleeve 1. The slider 12 is a rectangular slider, and the slide groove in the telescopic rod sleeve 1 is also a rectangular slide groove. Therefore, the rectangular slide groove limits the rotation of the rectangular slider, which will push the rectangular slider forward or backward to drive the telescopic rod 2 to extend and retract. The interior of the telescopic rod 2 is a hollow structure. When the telescopic rod 2 is retracted, the screw rod 11 is inserted into the hollow structure;

[0031] When in use, a certain number of connecting rods 3 can be selected according to the requirements of the test. If the total length of the pulling rod 19 is 5 meters, the extended length of the telescopic rod 2 is 2 meters, the connecting rod 3 is 1 meter long, and the test requirement is 8.5 meters, then two connecting rods 3 can be selected. The total length of the telescopic rod, the pulling rod 19 and the two connecting rods 3 is 9 meters. The extra 0.5 meter can be adjusted by retracting the telescopic rod 2 by 0.5 meters. Because the telescopic rod 2 is provided with a scale, retracting 0.5 meters is very convenient and flexible.

[0032] The connecting rod 3 is connected to the telescopic rod 2 and the pulling rod 19 by a connecting sleeve 9, and is reinforced by a dual method of magnetic attraction and spring button 16 to prevent it from falling off and causing losses, and the disassembly and assembly is very simple and convenient.

[0033] The above embodiments merely represent implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
