Abstract
Description
A quick-release type of fishing boat depth sounder fixing device Technical Field
[0001] This utility model relates to the technical field of depth sounders for fishing vessels, and in particular to a quick-release fixing device for a depth sounder for fishing vessels. Background Technology
[0002] A depth sounder for fishing vessels is an instrument that uses sound waves to measure the water depth at the location of a fishing vessel. It provides fishermen with accurate water depth information, assisting them in safe navigation and fishing operations. Using a fixed device to secure the depth sounder serves several purposes: first, it ensures measurement accuracy by allowing sound waves to be emitted and received perpendicularly, avoiding errors caused by instrument movement or displacement; second, it ensures the safety of the instrument, protecting it from damage such as collisions or drops in complex sea conditions; and third, it facilitates operation and maintenance, as the fixed location makes it convenient for crew members to operate and read data, and also facilitates regular maintenance and repairs by maintenance personnel.
[0003] The prior art patent number CN116466370A proposes a fixed connection device for a marine GNSS receiver and a depth sounder transducer, including a depth sounder transducer, a GNSS receiver, a probe rod, and a combined fixing connector. By installing and using the probe rod and the combined fixing connector, the depth sounder transducer and the GNSS receiver can be combined with fishing boats, rubber boats, and maritime patrol boats. Not only can the three-dimensional spatial coordinates of a point be obtained in real time above the water surface through the GNSS receiver, but the water depth at the bottom of the transducer can also be obtained by the change in the position of the vehicle. Even if the navigation encounters fishing nets, aquatic plants, dams, control gates, low bridges, or other places where direct navigation is not possible, the probe rod, which has been assembled with the GNSS receiver and depth sounder transducer, can be rotated around the central axis of the long screw in the combined fixing connector by tightening and loosening the screws on the combined fixing connector. After being placed flat, the entire measuring equipment can be transported manually to places inaccessible by vehicles or ships to complete the measurement.
[0004] Problems identified in existing technologies: The combination fixed connector mainly relies on screws for connection and fixation. During long-term use, due to the impact of ship rocking, vibration and harsh environments such as seawater, the screws may loosen or even fall off. This will affect the stability of the equipment connection and the accuracy of measurement, and in severe cases, may cause the equipment to fall and be lost. Summary of the Invention
[0005] To address the above technical problems, this utility model provides a quick-release fishing boat depth sounder fixing device, characterized by comprising a load-bearing structure, an adjustment structure, and a fixing structure. The adjustment structure is disposed above the load-bearing structure, and the load-bearing structure and the adjustment structure are connected by welding. The fixing structure is disposed above the adjustment structure, and the adjustment structure and the fixing structure are connected by welding.
[0006] The load-bearing structure consists of fixed supports, fixed legs, a load-bearing platform, a switch door, and a load-bearing seat. The fixed supports and fixed legs are located below the load-bearing platform. The load-bearing platform is connected to the fixed supports and fixed legs by welding. Placement slots are opened on both sides of the load-bearing platform, and a switch door is located outside the placement slot. The load-bearing platform and the switch door are connected by hinges. A load-bearing seat is located on one side of the load-bearing platform, and the load-bearing platform and the load-bearing seat are connected by a pivot.
[0007] The adjustment structure consists of a buffer seat, a motor, and an offset plate. The motor is located on one side of the buffer seat and is connected to it by welding. An offset plate is located on one side of the motor and is also connected to it by welding. The buffer seat comprises a buffer body, connecting components, and a protective shell. The protective shell encloses the buffer body, and the connecting components are used to fix the protective shell and the buffer body.
[0008] The fixing structure consists of a mounting base, a telescopic rod, and a magnetic clamp. The telescopic rod is located on one side of the mounting base, and the mounting base and the telescopic rod are connected by welding. A magnetic clamp is located on one side of the telescopic rod, and the telescopic rod and the magnetic clamp are connected by welding. A threaded insertion groove is provided on one side of the mounting base; the telescopic rod is an electrically operated telescopic rod; and the magnetic clamp is an electromagnetically operated clamp.
[0009] The beneficial effects of this utility model are as follows:
[0010] This utility model improves the load-bearing structure, which consists of a fixed support column, fixed legs, a load-bearing platform, a switch door, and a load-bearing seat. It allows for the installation of the fixed support column by inserting it into a slot on the ship and then integrally casting it, forming a tight, unified structure with the hull. During navigation, it effectively resists external forces caused by severe rocking and turbulence in complex sea conditions, preventing the depth sounder from shifting due to shaking and ensuring stable operation. This provides accurate depth data for the fishing vessel. The fixed legs are secured to the ship with expansion bolts, further enhancing the stability of the connection between the entire fixing device and the hull. The load-bearing seat can be used in emergencies; in such situations, staff can quickly flip the seat and sit on it, cleverly integrating their weight into the fixing system. For example, when the hull is severely tilted and the depth sounder is at risk of shifting, this method significantly increases the load-bearing capacity of the fixing device, increasing friction and stability, effectively preventing the depth sounder from shifting under extreme conditions, and providing a strong guarantee for the stable operation of critical equipment.
[0011] This invention improves the adjustment structure, which consists of a buffer seat, a motor, and an offset plate. The buffer seat can effectively reduce the impact of vibrations and turbulence generated by the fishing boat during navigation on the depth sounder. The motor-driven offset plate can precisely adjust the position and angle of the depth sounder according to actual needs. For example, when the fishing boat is in different navigation postures or encounters special measurement needs, the motor can precisely control the offset plate to put the depth sounder in the optimal measurement position, thereby improving the accuracy and reliability of the measurement.
[0012] This invention improves the fixing structure, which consists of a mounting base, a telescopic rod, and a magnetic clamp. The fixing structure allows the depth sounder to be inserted into the threaded insertion slot at the bottom of the mounting base. The operation is simple and direct, and it can quickly complete the initial positioning. With the help of the electromagnetic clamp, the depth sounder can be firmly fixed by generating magnetic force when energized. When disassembly is required, simply cut off the power, and the clamp will lose its attraction, allowing the depth sounder to be easily removed from the threaded insertion slot. This greatly saves time and labor costs for installing and maintaining the depth sounder. Attached Figure Description

[0020] Example 2
[0021] When using this invention, a threaded pin is first welded to the bottom of the depth sounder. An installation slot is then created on the fishing boat. The fixing support 1 is inserted into the slot and integrally cast, forming a tight bond between the fixing support 1 and the hull. The fixing feet 2 are then fixed to the boat with expansion bolts, further enhancing the stability of the entire fixing device's connection to the hull. In an emergency, workers can quickly flip the load-bearing seat 5 and sit on it, cleverly integrating their own weight into the fixing system.

The buffer seat 6 effectively reduces the impact of vibrations and turbulence generated during the fishing boat's voyage on the depth sounder. The motor 7 drives the offset plate 8 to precisely adjust the position and angle of the depth sounder according to actual needs, placing it in the optimal measurement position and improving measurement accuracy and reliability.
