Description

TECHNICAL FIELD

[0001] The utility model relates to a depth finder ship bottom mounting structure technical field especially point to a kind of new shallow water depth finder ship bottom mounting structure for fishing boat. BACKGROUND

[0002] At present, the bottom mounting surface of most fishing boats on the market is inclined, and the cabin above the bottom plate is also filled with a certain thickness of cement. If the conventional installation scheme is followed, the transducer mounting seat is directly welded to the bottom plate, and the mounting seat protrudes from the bottom. When the ship is sailing, air bubbles will be generated, affecting the performance of the equipment. In order to ensure that the installation surface is not affected when pouring cement, the length of the transducer mounting seat needs to be greatly lengthened (to ensure that the cement is exposed). This will increase the processing cost of parts (the material is stainless steel 316L) and the difficulty of construction.

[0003] In view of the characteristics of unstable performance after installation, high cost of mounting parts and great difficulty in on-site construction of the shallow water depth finder for fishing boat, a new type of ship bottom mounting structure is designed, which is not only reliable, economical and practical, but also easy to operate, and is very worth promoting. SUMMARY

[0004] To solve the above technical problems, the utility model discloses a new type of shallow water depth finder ship bottom mounting structure for fishing boat, which comprises a flange assembly, a fairing is arranged on the outer side of the flange assembly, and the flange assembly and the fairing are connected by welding; a transducer mounting seat is further arranged in the flange assembly, and is welded to the lower flange on one side, while the fairing is welded to the lower flange, and the lower flange is provided with an upper flange on one side, and a sealing gasket is arranged on the contact surface.

[0005] One end of the flange assembly is provided with a cover plate assembly, which is connected to the transducer mounting seat through a cover plate and a sealing ring I; a transducer is arranged on one end surface of the cover plate, and is connected to the transducer through a nut and a sealing ring II.

[0006] In one embodiment of the utility model, the lower flange in the flange assembly is connected by welding to the transducer mounting seat, and the bottom surfaces of the two are flush with each other, and the lower flange is welded to the bottom plate of the fishing boat (the size of the hole in the bottom is slightly larger than the outer diameter of the lower flange).

[0007] In one embodiment of the utility model, a sealing gasket is arranged between the upper flange and the lower flange, and the two are connected by screw assembly after assembly.

[0008] In one embodiment of the utility model, the fairing is welded to the bottom plate of the fishing boat on four sides, and the bottom hole (the size is slightly larger than the outer diameter of the lower flange) is welded to the outer side of the lower flange, and the bottom surface of the lower flange is flush with the plane after assembly.

[0009] The ship bottom mounting structure of the fishing boat shallow depth finder has the following advantages compared with the prior art: the part protruding from the ship bottom is welded with a flow guide cover, which can reduce the generation of bubbles during ship navigation, improve the measurement accuracy, the outside of the transducer mounting seat is welded with a flange, which can reduce the part processing cost and the operation difficulty during on-site construction.

[0016] The embodiment provides a novel fishing boat shallow depth finder ship bottom mounting structure, which comprises: a flange assembly 1, a cover plate assembly 2 and a flow guide cover 3.

[0017] As Figure 1 shown, the ship bottom is holed, the flange assembly 1 is welded with the ship bottom plate, the horizontal precision of the bottom surface is ensured to be within the required range, due to the inclination of the ship bottom surface, the flange assembly 1 protrudes from the ship bottom after welding, bubbles are generated during ship navigation, which affects the equipment performance, therefore, the flow guide cover 3 is welded outside the flange assembly 1, the part protruding from the ship bottom is wrapped therein, the bottom surface of the flow guide cover 3 is flush with the bottom surface of the flange assembly 1. The sealing ring 19 is smeared with butter and put into the sealing groove, the cover plate assembly 2 and the flange assembly 1 are connected through screws, the transducer 12 is ensured to be flush with the bottom surface of the flow guide cover 3 or slightly protrude.
