TECHNICAL FIELD

[0001] The present application relates to a fishing boat fish collecting lamp, in particular to a fish collecting lighting device with adjustable irradiation angle. BACKGROUND

[0002] When the fishing boat is performing light fishing operation, the common practice is to install multiple fish collecting lamps (also known as fish attracting lamps) on the fishing boat, and through the light emitted by the fish collecting lamps, the fish in the illumination range are attracted together by the phototaxis of the fish, so as to facilitate fishing. The position of the existing fish collecting lamp is fixed after installation. When performing light fishing operation, the irradiation angle of the fish collecting lamp cannot be adjusted, which will affect the fishing effect.

[0003] A fish collecting lamp angle adjusting device is disclosed in Chinese Patent Publication No. CN114413207A, published on April 29, 2022, which comprises at least one fixed pipe, a rotating pipe corresponding to the fixed pipe, the rotating pipe being sleeved outside the fixed pipe, the rotating pipe being used for connecting with an external fish collecting lamp, a rotating mechanism corresponding to the fixed pipe, the rotating mechanism being connected with the fixed pipe and the rotating pipe respectively, and the rotating mechanism being capable of driving the rotating pipe to rotate relative to the fixed pipe under the action of external force. The fixed pipe is installed on the fishing boat, the rotating pipe is sleeved outside the fixed pipe and the fish collecting lamp is installed on the rotating pipe, the rotating mechanism is connected with the fixed pipe and the rotating pipe respectively, the rotating mechanism is driven by a driver such as a hydraulic cylinder, the rotating mechanism drives the rotating pipe to rotate relative to the fixed pipe, the fish collecting lamp is rotated relative to the fishing boat, the effect of adjusting the light emitting angle of the fish collecting lamp is realized, and the light efficiency is improved. The fish collecting lamp angle adjusting device has the following defects: (1) the fish collecting lamp angle adjusting device contains a rotating mechanism and other structures, the rotating mechanism needs to be driven by a driver such as a hydraulic cylinder, so that the rotating pipe can rotate relative to the fixed pipe, the structure is relatively complex, and the disassembly, assembly and maintenance are not convenient, and the maintenance cost is high; (2) the adjustment range of the angle of the fish collecting lamp is limited by the stroke of the driver, and the adjustment range of the angle of the fish collecting lamp is small. SUMMARY

[0004] The present application is to solve the above-mentioned problems of the fish collecting lamp angle adjusting device in the prior art, and provides a fish collecting lighting device with adjustable irradiation angle, which has simple structure, low maintenance cost, rapid and convenient irradiation angle adjustment, large angle adjustment range and good use stability.

[0005] In order to achieve the above object, the present application adopts the following technical scheme: a fish gathering lighting device with adjustable illumination angle, comprising a bottom plate, a rotating pipe and a mounting bracket, at least one support pipe seat is arranged on the bottom plate, the rotating pipe passes through the support pipe seat and is rotatably connected to the support pipe seat, the mounting bracket is fixed on the rotating pipe, the fish gathering lamp is arranged on the mounting bracket, and a winding and unwinding rope is connected to the top of the mounting bracket; the locking and positioning mechanism is arranged between the rotating pipe and the bottom plate, when the rotating pipe is separated from the locking and positioning mechanism, the rotating pipe rotates relative to the support pipe seat, and when the rotating pipe is limited by the locking and positioning mechanism, the rotating pipe is locked and positioned relative to the support pipe seat. The bottom plate is fixed on the fishing boat; the support pipe seat is used for fixing and supporting the rotating pipe, the rotating pipe is fixed in the axial direction after installation and cannot be moved; the fish gathering lamp is a prior art, which can be a halogen lamp or an LED lamp, and can be selected and installed according to actual needs; the winding and unwinding rope is connected to the winch, the winding and unwinding rope can be wound and unwound through the winch, and the winding and unwinding rope will pull or lower the mounting bracket (so that the mounting bracket rotates around the rotating pipe as the shaft) when winding and unwinding, so that the inclination angle of the mounting bracket can be quickly adjusted, the illumination angle of the fish gathering lamp can be quickly adjusted, when the angle adjustment is completed, the winding and unwinding rope can pull the mounting bracket, in addition, the length of the winding and unwinding rope is long, so that the angle adjustment range of the mounting bracket can be large; since the mounting bracket in the present application is only kept fixed by the interaction of the self weight and the winding and unwinding rope, the rotating pipe is prone to rotation, so that the mounting bracket is prone to rotation, the stability is poor, the illumination angle of the fish gathering lamp is affected, and the winding and unwinding rope is also subjected to rope loosening impact, which is prone to breakage of the winding and unwinding rope, therefore, the locking and positioning mechanism is arranged in the present application to limit and position the rotating pipe, so that the rotating pipe can always be kept fixed, the stability of the rotating pipe is ensured, and rotation of the rotating pipe is avoided.

[0006] As preferred, the locking positioning mechanism comprises rotating toothed discs fixed at both ends of the rotating tube, and an elastic extension mechanism fixed on the bottom plate outside the rotating toothed discs, the handle is connected with the elastic extension mechanism, the handle is provided with locking teeth, when the elastic extension mechanism is in the natural state, the locking teeth engage with the rotating toothed discs, the rotating tube is limited by the locking positioning mechanism, and the rotating tube is locked and positioned relative to the support tube base, when the elastic extension mechanism is in the compressed state, the locking teeth are disengaged from the rotating toothed discs, the rotating tube is disengaged from the limitation of the locking positioning mechanism, and the rotating tube rotates relative to the support tube base. The rotating toothed discs in the application can rotate coaxially with the rotating tube, when the elastic extension mechanism is in the natural state, the locking teeth engage with the rotating toothed discs, the rotating toothed discs are limited by the fixed locking teeth and cannot rotate, so that the rotating tube cannot rotate, and thus the position of the rotating tube is fixed; when the handle is pulled outward, the elastic extension mechanism is in the compressed state, the locking teeth are disengaged from the rotating toothed discs, at this time, the rotating toothed discs and the rotating tube can rotate, so that the inclination angle (i.e. the illumination angle of the fish gathering lamp) of the installation support can be adjusted by winding and unwinding the rope; the rotating tube is locked and positioned by the cooperation of the locking teeth and the rotating toothed discs, and the structure is simple and convenient to use.

[0007] As preferred, a mounting vertical plate is fixed on the bottom plate outside the rotating toothed discs.

[0008] As preferred, the elastic extension mechanism comprises a spring cylinder base, a spring, a connecting rod and a piston sliding block, the spring cylinder base is fixed on the mounting vertical plate, the piston sliding block is arranged in the spring cylinder base, the connecting rod passes through the spring cylinder base and is in sliding cooperation with the spring cylinder base, the inner end of the connecting rod is fixedly connected with the piston sliding block, and the outer end of the connecting rod is fixedly connected with the handle, the spring is arranged in the spring cylinder base and surrounds the connecting rod, and the two ends of the spring are respectively abutted against the piston sliding block and the spring cylinder base. When the handle is pulled outward (away from the spring cylinder base), the connecting rod drives the piston sliding block to compress the spring, so that the locking teeth are disengaged from the rotating toothed discs; when the spring returns to the original position, the locking teeth can engage with the rotating toothed discs again.

[0009] As preferred, at least one of the spring barrel seats is provided with a one-way retreat-preventing mechanism, and the connecting rod passes through the one-way retreat-preventing mechanism, which is used to limit the movement of the connecting rod towards the spring barrel seat. The one-way retreat-preventing mechanism is used to limit the movement of the connecting rod towards the spring barrel seat, that is, the connecting rod cannot move towards the spring barrel seat, but can only move away from the spring barrel seat. With this design, the connecting rod can only move in one direction. When the inclination angle of the mounting bracket needs to be adjusted, the pull handle does not need to be pulled all the time to make the locking tooth block disengage from the rotating tooth disc. After the pull handle is pulled outwards to make the locking tooth block disengage from the rotating tooth disc, the pull handle can be released. At this time, the connecting rod cannot be reset (that is, it cannot move towards the spring barrel seat) under the action of the spring. In this way, the locking tooth block can always remain disengaged from the rotating tooth disc, so as to facilitate the adjustment of the inclination angle of the mounting bracket by the release and take-up rope.

[0010] As preferred, the one-way retreat-preventing mechanism comprises a mounting seat fixed at the outer end of the spring barrel seat, a moving seat and a reset spring. The mounting seat is provided with a mounting cavity. The inner wall of the mounting cavity is provided with a tapered extrusion surface at the upper part. The moving seat is arranged in the mounting cavity. The end of the moving seat close to the spring barrel seat is fixed with a positioning bowl. The side surface of the positioning bowl is provided with at least three positioning through grooves at intervals. The positioning through grooves are provided with steel balls which can move up and down along the positioning through grooves. The reset spring is arranged between the moving seat and the mounting seat. The connecting rod passes through the spring barrel seat, the mounting seat, the positioning bowl and the reset spring. The steel balls are arranged around the connecting rod. The two ends of the reset spring are respectively abutted against the mounting seat and the moving seat. When the reset spring is in a natural state, the tapered extrusion surface extrudes the steel balls, so that the steel balls lock the connecting rod in the radial direction. The mounting seat is provided with a sliding long hole. The sliding long hole is provided with a pushing piece. The lower end of the pushing piece is fixedly connected with the moving seat. When the moving seat moves, the steel balls are located in the positioning through grooves and can move along the positioning through grooves. When the reset spring is in a natural state, the moving seat makes the steel balls abut against the tapered extrusion surface under the action of the reset spring. The tapered extrusion surface will exert a reverse extrusion force on the steel balls, so as to lock (tighten) the connecting rod in the radial direction. If the connecting rod moves towards the spring barrel seat, the connecting rod will drive the steel balls to further abut against the tapered extrusion surface, causing the tapered extrusion surface to further extrude the steel balls, so as to lock the connecting rod more tightly. If the pull handle is pulled to move the connecting rod away from the spring barrel seat, at this time, the steel balls will loosen the connecting rod in the radial direction, so that the connecting rod can be pulled outwards. When the pushing piece is pushed outwards (so that the moving seat moves away from the spring barrel seat), the steel balls will loosen the connecting rod. At this time, the connecting rod can move freely (bidirectionally).

[0011] As preferred, the positioning bowl is a hollow circular cone structure.

[0012] As preferred, the end of the moving seat away from the spring barrel seat is provided with a reset spring limiting groove. The reset spring is arranged in the reset spring limiting groove.

[0013] As preferred, the support pipe base comprises an outer sleeve and a support plate, the support plate is fixed at the bottom of the outer sleeve, the rotating pipe passes through the outer sleeve and is fixed in the outer sleeve through a bearing.

[0014] As preferred, the mounting bracket comprises support rods and mounting beams, the lower part of the support rods is fixedly connected with the rotating pipe, the mounting beams are fixedly arranged between the support rods from top to bottom, and the fish gathering lamp is arranged on the mounting beams.

[0015] The carrying capacity and stability of the product are increased,

[0016] Therefore, the present application has the following beneficial effects:

[0017] (1) Through the cooperation between the rotating pipe, the winding and unwinding rope and the locking and positioning mechanism, the inclination angle of the mounting bracket can be quickly adjusted, so that the illumination angle of the fish gathering lamp can be quickly adjusted, and the angle adjustment range is large.

[0018] (2) The structure is simple, the maintenance cost is low, and the use stability is good. BRIEF DESCRIPTION OF DRAWINGS
