Detailed implementation manners

[0023] The embodiments of the present utility model will be described in detail below. Refer to Figure 1 , the embodiments of the present utility model provide a fish finder bracket, which includes a connecting frame 100, a steering drive mechanism 200, a steering rod 300 and a fish finder 400. The connecting frame 100 is used to connect with the gear box 500 of the propeller. The steering drive mechanism 200 is arranged on the connecting frame 100 and is installed on the propeller through the connecting frame 100. The steering rod 300 is connected to the steering drive mechanism 200 and can rotate under the drive of the steering drive mechanism 200. A fish finder 400 is arranged at the lower end of the steering rod 300 and can extend under the water surface along with the lower end of the steering rod 300. The fish finder 400 is used to detect the underwater situation and the position of the fish school. For the fish finder bracket according to the embodiment of the present utility model, the fish finder 400 can be installed on the gear box 500 of the propeller and can rotate independently under the drive of the steering drive mechanism 200, adjusting the detection direction independently of the direction of the main motor 220 of the propeller. The detection direction is not limited by the direction of the main motor 220, which is convenient for controlling the detection direction. Moreover, the fish finder 400 is installed on the gear box 500 of the propeller through the steering rod 300, the steering drive mechanism 200 and the connecting frame 100, and can be retracted and extended together with the propeller, and the detection direction will not be affected by the water surface fluctuation.

[0024] Refer to Figure 1, in this embodiment, the connecting frame 100 includes an upper connecting plate 110, two side support plates 120 and a lower support base 130. The upper connecting plate 110 is connected to the gearbox 500 of the thruster. The steering drive mechanism 200 is arranged on the upper connecting plate 110, and the upper connecting plate 110 is provided with a through hole through which the steering rod 300 can pass. The lower support base 130 is connected to the base 600 of the gearbox 500, and the two side support plates 120 are both arranged between the upper connecting plate 110 and the lower support base 130 to improve the strength of the connecting frame 100.

[0025] In some embodiments, the gearbox 500 of the thruster is rotatably arranged on the base 600. The main rod and the main motor 220 of the thruster can be pressed against the bottom of the ship or vertically inserted into the water by rotating the gearbox 500, so as to realize the retraction and extension of the thruster. To facilitate the retraction and extension of the fish finder 400 and the thruster together, the lower support base 130 is provided with a U-shaped groove 131 through which the steering rod 300 can pass, and the opening direction of the U-shaped groove 131 faces the rotation direction when the thruster is retracted. After the steering rod 300 is released along with the main rod of the thruster, the steering rod 300 rotates from horizontal to vertical and falls into the U-shaped groove 131 from the opening of the U-shaped groove 131, and the two side support plates 120 are installed on both sides of the steering rod 300. When retraction is needed, the two side support plates 120 are removed, and then the gearbox 500 is rotated. The steering rod 300 will change from vertical to horizontal and be attached to the bottom of the ship as the gearbox 500 rotates, and the steering rod 300 will escape from the U-shaped groove 131 through the opening of the U-shaped groove 131. In some embodiments, the lower end of the side support plate 120 can be set to a circular arc shape or other shapes that will not interfere with the lower support base 130 during the rotation process. The lower support base 130 can be provided with two chutes corresponding to the width and position of the side support plates 120. When the fish finder 400 is released, the side support plates 120 can directly slide into the corresponding chutes to avoid disassembling and assembling the side support plates 120 when the fish finder 400 is retracted and extended.

[0026] It can be understood that the steering drive mechanism 200 can be composed of a motor 220 and a transmission mechanism such as a gear set or a synchronous belt mechanism. The motor 220 and the transmission mechanism are arranged in the steering box 210, and the output shaft of the motor 220 is in transmission connection with the steering rod 300 through the transmission mechanism. Refer to Figures 2 to 4, in this embodiment, the transmission mechanism includes a main gear 240, at least one transmission gear 230, and a steering rod connector 250. The main gear 240 and the transmission gear 230 are both rotatably disposed in the transmission box. The steering rod connector 250 is detachably connected to the steering rod 300 and the main gear 240. The main gear 240 is connected to the steering rod 300 through the steering rod connector 250. The output shaft of the motor 220 is drivingly connected to the main gear 240 through the transmission gear 230. The number of the transmission gears 230 can be set according to actual needs. In this embodiment, only one transmission gear 230 is included. The transmission gear 230 is directly connected to the output shaft of the motor 220. The transmission ratio of the gear set composed of the transmission gear 230 and the main gear 240 should be relatively large to reduce the rotation speed of the main gear 240 and increase the output torque of the main gear 240.

[0027] To facilitate the disassembly and assembly of the fish finder bracket and the adjustment of the depth of the fish finder 400, refer to Figures 2 to 4, in this embodiment, the steering box 210 is formed by fitting together a left half-box 211 and a right half-box 212 from left to right. After fitting, a first through-hole through which the steering rod 300 can pass is provided at the fitting portion. The motor 220 is disposed in the right half-box 212. The left half-box 211 includes a lower left box body 2112 and an upper left cover 2111, and the right half-box 212 includes a lower right box body 2122 and an upper right cover 2121. The motor 220 is disposed in the motor 220 compartment of the lower right box body 2122. The upper left cover 2111 and the upper right cover 2121 are respectively detachably connected to the lower left box body 2112 and the lower right box body 2122 by bolts. One end of the lower left box body 2112 and the lower right box body 2122 is hinged by a hinge, and a locking seat 213 is provided at the other end. The locking seat 213 is provided with a bolt hole through which a locking bolt can pass, and a locking handle 214 is provided at one end of the locking bolt for manual rotation. The main gear 240 is also formed by fitting together a left half-gear 241 and a right half-gear 242 from left to right. After fitting, a second through-hole through which the steering rod 300 can pass is provided at the center, and the second through-hole is concentric with the first through-hole. The steering rod connector 250 includes a left clamping member 251 and a right clamping member 252. After the left clamping member 251 and the right clamping member 252 are fitted together, the steering rod 300 can be clamped between the two. One end of the left clamping member 251 and the right clamping member 252 is hinged by a hinge, and an adjusting seat 253 is provided at the other end. The adjusting seat 253 is provided with a bolt hole through which an adjusting bolt 254 can pass. An adjusting handle is provided at one end of the adjusting bolt 254 for manual loosening and tightening of the adjusting bolt 254. The distance between the two adjusting seats 253 can be adjusted by rotating the tightening and loosening bolt to adjust the tightness of the clamping of the steering rod 300. First tooth portions are provided at the lower ends of the left clamping member 251 and the right clamping member 252, and second tooth portions matching the first tooth portions are provided on the inner side wall of the second through-hole of the main gear 240. The steering rod connector 250 can be detachably connected to the main gear 240 by inserting the first tooth portion into the second tooth portion. When the main gear 240 rotates, torque is transmitted through the engagement of the second tooth portion and the first tooth portion to drive the steering rod 300 to rotate so as to adjust the direction of the fish finder 400. In this embodiment, the teeth of the first tooth portion are wider at the top and narrower at the bottom, and the tooth grooves of the corresponding second tooth portion are wider at the top and narrower at the bottom to form a guide during the process of inserting the steering rod connector 250 into the main gear 240. An annular boss is provided on the lower end surface of the main gear 240, and an annular groove matching the annular boss is provided on the inner bottom surface of the steering box 210. The main gear 240 is rotatably disposed in the steering box 210 by embedding the annular boss into the annular groove.

[0028] During installation, first pass the upper end of the steering rod 300 through the through-hole of the upper connecting plate 110, then clamp the steering rod connector 250 to the upper end of the steering rod 300, but do not tighten the locking bolt. Open the left half box 211 and the right half box 212, and at the same time open the left half gear 241 and the right half gear 242 inside the left half box 211 and the right half box 212. Place the middle part of the steering rod 300 at the groove for forming the second through-hole, and then join the left half box 211 and the right half box 212 together. At the same time, join the left half gear 241 and the right half gear 242 together, and fix the two locking seats 213 together by tightening the locking bolt. Then install the steering box 210 onto the upper connecting plate 110 with bolts. Then, according to the depth required by the lower fish finder 400, adjust the height of the steering rod connector 250 on the steering rod 300. After adjusting to the appropriate height, tighten the adjusting bolt 254. Finally, insert the steering rod connector 250 into the main gear 240 so that the first tooth part and the second tooth part are inserted and engaged.
