[0005] In response to the above problems, existing patents have provided solutions, but they lack the integrated structure of the shipborne GPS and depth sounder, which makes it difficult to ensure high-precision positioning and stable posture between the GPS locator and the depth sounder probe, thereby reducing the accuracy of the measurement results.

[0006] Therefore, a shipborne GPS depth sounder integrated measuring device is proposed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 , this utility model provides a technical solution:

[0028] A shipborne GPS depth sounder integrated measuring device includes a shipborne GPS body 1, a base 2 is fixedly connected to the bottom of the shipborne GPS body 1, a rotation mechanism 3 is fixedly connected to the right side of the front side of the base 2, a depth sounder body 4 is fixedly connected to the rear side of the shipborne GPS body 1, and a connecting mechanism 5 is welded to the surface of the depth sounder body 4;

[0029] The rotating mechanism 3 includes a stepping motor 31, four gears 32, two winding rods 33 and a connecting rope 34. The stepping motor 31 is fixedly connected to the right side of the front side of the ship-borne GPS body 1. The gear 32 is rotatably connected to the bottom of the rear surface of the ship-borne GPS body 1. The four gears 32 are engaged with each other. The winding rods 33 are respectively fixedly connected to the rear sides of the right gear 32 and the left gear 32. The connecting rope 34 is wound around the surface of the winding rod 33. The side of the connecting rope 34 away from the winding rod 33 is fixedly connected to the inner side of the connecting mechanism 5.

[0030] In this embodiment: by setting up the ship-borne GPS body 1, the precise geographical location information of the ship in the water area can be obtained in real time, including data such as longitude, latitude and elevation, providing an accurate position reference for the entire measurement work. The base 2 can firmly install the GPS body on the ship, bear the weight of the equipment itself and the external forces caused by shaking, bumping, etc. during the navigation of the ship, and can support and limit the stepper motor 31 and the gear 32. The depth sounder body 4 is based on the principle of sound wave propagation and reflection in water, and can accurately measure the water depth at different positions under the ship, providing key depth data for underwater terrain mapping. The stepper motor 31 can facilitate the operator to set the rotation angle of the stepper motor 31. The degree and number of steps can accurately control the retraction and extension length of the connecting rope 34 and the position adjustment of the depth sounder body 4. The transmission system formed by the mutual meshing of the four gears 32 can smoothly and evenly transmit the power output by the stepping motor 31 to the winding rod 33. The winding rod 33 is fixedly connected to the rear sides of the right gear 32 and the left gear 32 respectively, so that the connecting rope 34 can achieve bilateral balanced force during the retraction and extension process. This bilateral arrangement avoids the uneven force problem that may occur when using only one winding rod 33. The connecting rope 34 is made of Kevlar fiber material and also plays the role of transmitting power. It can convert the rotation of the winding rod 33 into the lifting and lowering movement of the depth sounder, thereby realizing the control of the depth sounder's position in the water.

[0031] Specifically, such as Figure 3 As shown, the connecting mechanism 5 includes a fixing ring 51 , two supporting rods 52 and a connecting ring 53 , and the fixing ring 51 is welded to the surface of the depth sounder body 4 .

[0032] Specifically, such as Figure 3 As shown, the support rods 52 are fixedly connected to both sides of the top of the fixing ring 51 , and the connecting ring 53 is welded to the top of the support rods 52 .

[0033] Specifically, such as Figure 3 As shown, the inner side of the connecting ring 53 is fixedly connected to the end of the connecting rope 34 away from the winding rod 33 , and the inner side of the connecting ring 53 is fixedly connected to the protective pad 6 .

[0034] In this embodiment: by setting a fixing ring 51, a stable connection foundation is built between the entire connecting mechanism 5 and the depth sounder, and the support rods 52 are fixedly connected to both sides of the top of the fixing ring 51, respectively, which plays a strong supporting role for the connecting ring 53, and can effectively prevent the connecting ring 53 from being deformed when subjected to vertical tension, such as the tension when the connecting rope 34 pulls the depth sounder. The connecting ring 53 serves as a connection between the connecting rope 34 and the entire connecting mechanism 5, preventing the connecting rope 34 from accidentally falling off during frequent retraction and extension. By setting a protective pad 6, when the connecting rope 34 is frequently retracted and extended, the protective pad 6 can effectively reduce the friction between the connecting rope 34 and the connecting ring 53, avoiding wear and breakage of the connecting rope 34 due to long-term friction, and extending the service life of the connecting rope 34.

[0035] Specifically, such as Figure 4 As shown, a reinforcement ring 7 is fixedly connected to the bottom of the support rod 52 , and a side of the reinforcement ring 7 away from the support rod 52 is welded to the top of the fixing ring 51 .

[0036] Specifically, such as Figure 5 As shown, a sealing ring 8 is fixedly connected to the top of the depth sounder body 4 , and a side of the sealing ring 8 away from the depth sounder body 4 is fixedly connected to the rear side of the shipborne GPS body 1 .

[0037] In this embodiment: by providing a reinforcement ring 7, the reinforcement ring 7 can more evenly distribute the external force borne by the support rod 52 to the fixing ring 51, effectively preventing the connection between the support rod 52 and the fixing ring 51 from loosening, deformation, etc. due to concentrated force. By providing a sealing ring 8, it is possible to prevent external water from penetrating into the connection between the shipborne GPS body 1 and the depth sounder body 4, avoiding damage to the internal electronic components and circuits due to the entry of water.

[0038] Specifically, such as Figure 2 As shown, the output end of the stepping motor 31 passes through the base 2 and is fixedly connected to the front side of the right gear 32 .

[0039] Specifically, such as Figure 4 As shown, a plurality of reinforcing rods 9 are welded to the bottom of the fixing ring 51 , and the bottoms of the reinforcing rods 9 are fixedly connected to the surface of the depth sounder body 4 .

[0040] In this embodiment: by setting the output end of the stepper motor 31 to pass through the base 2 and be fixedly connected to the front side of the right gear 32, a stable installation position is provided for the stepper motor 31, so that the motor can maintain a relatively stable posture during operation, reducing the displacement and vibration caused by external factors such as ship shaking. By setting the reinforcement rod 9, the connection strength between the fixing ring 51 and the depth sounder body 4 is further enhanced.

[0041] Working principle: First, the user fixes the shipborne GPS body on the predetermined working position on the ship with the help of the base 2. After the installation is completed, the shipborne GPS body is immediately started and starts working. When it is necessary to measure the underwater depth, the user sets the rotation angle and number of steps of the stepper motor 31. Then, the stepper motor 31 starts to run immediately after receiving the corresponding command. The power output first passes through the base 2 smoothly through the output end, and is then transmitted to the right gear 32 fixedly connected to it. Then, the transmission system composed of four mutually meshing gears 32 starts to operate. As the winding rod 33 starts to rotate under power drive, the connecting rope 34 wrapped around its surface starts to release the line. Since the other end of the connecting rope 34 is fixedly connected to the inner side of the connecting ring 53, the winding rod 33 continues to rotate. In the process of releasing the connecting rope 34, the depth sounder body 4 will slowly move downward along the connecting rope 34 under the combined action of gravity and the pulling of the connecting rope 34, gradually going deeper into the water. At the same time, the depth sounder body 4 also starts to work synchronously to measure the water depth. After the underwater depth measurement work is successfully completed, the user only needs to operate the control stepper motor 31 to reverse. At this time, the stepper motor 31 drives the gear 32 connected to it to reverse synchronously, and then drives the winding rod 33 to start the action of rewinding the connecting rope 34. In the process of the connecting rope 34 being gradually rewound, it will generate an upward pulling force. With this pulling force, the depth sounder body 4 can be driven to overcome the resistance of the water flow, slowly rise from underwater, and finally separate from the water flow, and smoothly return to the initial position, completing the reset operation of the entire measurement process and preparing for the next measurement operation.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
