Specifically, as shown in fig. 4, in some embodiments, the telescopic driving device 4 includes a screw 41, a threaded sleeve 42, and a nut 45. The nut 45 is rotatably disposed at a first end of the threaded sleeve 42, and a second end of the threaded sleeve 42 is provided with a rotatable connection structure for rotatably connecting with the lamp holder 3. The inner end of the screw rod 41 is in threaded connection with a nut 45 and can extend into the threaded sleeve 42; the outer end of the threaded rod 41 is provided with a rotary connection structure for connecting with the lamp cap 1. The motor 43 is fixedly mounted on the threaded sleeve 42 and is in transmission connection with the nut 45 through a transmission mechanism to drive the nut 45 to rotate, so that the telescopic driving device 4 is extended or shortened.

pin shafts

44a and 44 b; the two

pins

44a, 44b are both parallel to the shaft 11.

In other embodiments, as shown in fig. 5, the telescopic drive 4 comprises a connecting sleeve 46 and two connecting bases 47. The connecting bases 47 are provided with a rotary connecting structure and a screw rod 41; a guide rod 48 is provided on one of the connection bases 47 in parallel with the screw 41 thereof.

The telescopic driving device 4 adopts a thread pair to stretch, the structure has a self-locking characteristic, the lamp holder 3 and the metal halide lamp 2 cannot move accidentally, the thread pair also has strong driving capability, and the lamp holder 3 and the metal halide lamp 2 with large dead weight can be driven by small power. The self-locking feature, however, makes it necessary for the telescopic drive 4 to rely on a control system, which is difficult to rotate in the event of a failure of the control system.

As shown in fig. 6, in some embodiments, the swing driving device directly drives the lamp socket 3 to rotate by using a motor 61 and a gear transmission mechanism. The motor 61 is fixedly arranged on the lamp holder 3 and is in transmission connection with the lamp holder 1 through a gear set. In this embodiment, adopt motor 61 direct drive lamp holder 1 to rotate, compare in telescopic actuating mechanism, have better quick response ability. The gear transmission mechanism usually has no self-locking capability, so the motor 61 in this embodiment should have a band-type brake or adopt a stepping motor.

In the above embodiments, a manual control mode may be adopted as a backup. The manual control means that a user manually swings the metal halide lamp 2 to a corresponding angle and fixes it. The manual fixing mode can adopt a bolt for locking or adopt a bolt mode for locking.

In one embodiment, as shown in fig. 6, the base 1 is locked by bolts. The side of the lamp holder 3 is provided with a locking bolt 62, and the locking bolt 62 is in abutting contact with the lamp cap 1 through the inner end thereof to fix the lamp cap. The axis of the locking bolt 62 is parallel to the axis of rotation of the burner 1. The outer end of the locking bolt 62 is provided with a knob handle. In the process of manually swinging the metal halide lamp 2, the locking bolt 62 is loosened, so that the metal halide lamp 2 and the lamp cap 1 can be freely swung. After the metal halide lamp 2 swings to a predetermined angle, the locking bolt 62 is tightened, so that the inner end of the locking bolt 62 abuts against the side surface of the lamp holder 1 to fix the metal halide lamp 2 and the lamp holder 1, and the metal halide lamp 2 and the lamp holder 1 are maintained at the predetermined angle.

By this fixing, the metal halide lamp 1 can be angularly adjusted only in a stepwise manner. The number of the angle adjustment stages depends on the number of the bolt holes, and the step length of the angle adjustment depends on the distribution distance of the bolt holes.

For example, an operational amplifier can be used for building an integrating circuit with an output voltage value changing along with time, and the lamp posture control device can control the expansion length or the rotation angle of each control swing driving device according to the output voltage value of the integrating circuit. In this embodiment, the computer is used for control, and the programmability and the powerful computing ability of the computer can be fully utilized, but this is not a necessary way to implement the present invention, and the relay and the PLC can be used to implement the time sequence control as well. The implementation process of the control system may not require dedicated software, and the implementation manner is the prior art, and a person skilled in the art may implement the control system in the present embodiment according to the description of the present embodiment.

The back of the metal halide lamp 2 facing away from the ocean surface is provided with a side reflector 5 with a circular arc-shaped plate-shaped horizontal section. One side of the side reflector 5 facing the metal halide lamp 2 is a side reflecting surface, and two sides of the side reflector are bent towards the direction of the metal halide lamp 2, so that the horizontal section of the side reflecting surface of the side reflector 5 is arc-shaped. The top of the side reflecting shade 5 is fixedly connected with the lamp holder 1.

In addition, the side of the base 1 is fitted around with a top reflector 6 in the form of a beveled edge. The top reflector 6 is complementary with the side reflector 5 along the circumferential length of the lamp holder 1 to form a circle as shown in fig. 1 or 4, or two sides of the top reflector 6 extend to the upper part of the top edges of two sides of the side reflector 5 to shield the tops of two sides of the side reflector 5; the surface of the top reflector 6 facing the oblique lower side is a top reflecting surface, and a reflecting film is arranged on the surface of the top reflecting surface.

As shown in fig. 1 and 11, the lower surface of the top reflector 6 is a side surface of a solid of revolution, and the intersection line of the reference surface passing through the axis of the metal halide lamp 2 and the top reflecting surface of the top reflector 6 is a straight line. The top reflector 6 is used for reflecting the light emitted from the light emitting body 21 obliquely upward to the obliquely downward direction and shining on the sea surface. In order to ensure the reflecting effect of the top reflector 6, the intersection point of the tangent plane to the top reflecting surface of the top reflector 6 and the axis of the metal halide lamp 2 is higher than the lowest point of the luminous body 21 and lower than the lamp tube vertex of the metal halide lamp 2.

As shown in fig. 1 and 7, the side reflector 5 is made of polymer by injection molding, and the surface of the side reflective surface of the side reflector 5 is provided with a reflective film and an anti-corrosion film in sequence from inside to outside. The minimum distance B between the central axis of the metal halide lamp 2 and the lateral reflecting surface of the side reflecting cover 5 on the horizontal section is smaller than the curved surface radius R of the lateral reflecting surface of the circular arc-shaped side reflecting cover 5. The side reflecting cover 5 can reflect light rays generated by the metal halide lamp and irradiating the deck to the sea surface direction, so that light pollution and heat generated by the light rays on the deck are avoided, and the energy efficiency of the fish gathering lamp is improved.

In the prior art, a reflector usually adopts a parabolic section, and a lamp is arranged at the focus of the reflector, so that the reflected light of the reflector is more focused, but the reflector is not suitable for being applied to fishing boats. When the fishing boat jolts along with sea waves or the fish gathering lamp swings, the over-focused light beams quickly pass through the sea surface, so that the fishes cannot track and reflect the light in time, and the fish gathering effect is poor. And in this embodiment, the light that the side reflector was reflected is comparatively dispersed for the shape of side reflector 5 and the position relation between metal halide lamp 2 and the side direction reflector surface, when making the light beam that sends of fish gathering lamp have certain directive property, still have bigger illumination zone, can cover bigger sea area, when the fishing boat jolts or the swing of fish gathering lamp, it has better continuation at the illumination zone of sea formation, the fish of being convenient for is tracked, has better fish gathering effect.

In a specific embodiment, the ratio of the radius R of the curved surface of the lateral reflecting surface of the circular arc-shaped side reflector 5 to the radius of the metal halide lamp 2 is 4 to 7. The distance between the two sides of the side reflecting cover 5 and the metal halide lamp 2 is equal, and the plane passing through the two side edges of the side reflecting cover 5 passes through the metal halide lamp 2. The top edge of the side reflecting cover 5 is horizontally bent towards one side where the side reflecting surface is located to form a connecting edge, and the connecting edge is fixedly connected with the bottom of the lamp holder 1 through a screw. The vertical length of the lamp-side reflection cover 3 is greater than the vertical length of the metal halide lamp 2. The middle part of the lamp-side reflection cover 3 is provided with a slit 51 extending vertically. The slit 51 prevents the reflected light from passing through the light emitting body of the metal halide lamp 2 again, causing further heat accumulation thereof, and is advantageous in that the heat dissipation slit 51, which is the highest temperature portion of the reflector, is disposed at a position closest to the metal halide lamp 2.

In one embodiment, as shown in fig. 7 and 8, the distance B between the metal halide lamp 2 and the lateral reflecting surface of the side reflector 5 in the horizontal section is the distance between the central axis of the tubular metal halide lamp 2 and the vertical central axis of the side reflecting surface, and the distance is 0.2 to 0.8 times the radius R of the lateral reflecting surface of the side reflector 5. The distance range can achieve obvious energy-saving effect within the range set by the invention through theoretical calculation and actual tests, and moreover, the light bands irradiated and reflected are increased to a certain range, and the distance range has suitable illumination intensity and particularly prominent fish trapping effect.

Compared with fig. 8, the minimum distance between the metal halide lamp 2 and the side reflector 5 in fig. 9 is close to the radius R of the curved surface of the side reflector, which makes the reflected light of the side reflector 5 concentrated, and many emitted light may pass through the illuminant of the metal halide lamp 2, easily causing the illuminant to be overheated. Fig. 10 shows another comparative example, in the structure shown in fig. 10, the minimum distance between the metal halide lamp 2 and the side reflector 5 is larger than the radius R of the curved surface of the side reflector, which may make the side reflector 5 unable to effectively reflect the light emitted from the metal halide lamp 2, and the light emitted from the metal halide lamp 2 to the side rear direction cannot be reflected. Therefore, in the case shown in fig. 9 and 10, the light of the fish gathering lamp cannot be fully utilized, and the energy consumption is high, which is not favorable for attracting and catching fish.

As shown in fig. 1 and 11, the top edge and the bottom edge of the top reflector 6 are both circular arcs, and the ratio of the circular arc radius of the top edge to the circular arc radius of the bottom edge is 3 to 6. The edge of the bottom of the top reflector 6 extends towards the inner side of the top reflector to form a connecting edge, and the connecting edge is fixedly connected with the bottom surface of the lamp holder 1 through a bolt. The top reflector 6 is of a thin shell structure, and the upper surface of the top reflector is provided with an anticorrosive film.

In this embodiment, the gradual fish gathering means that light emitted from the swing type fish gathering lamp can move from far to near, so that fish far away from the fishing boat can be attracted by the light. One necessary condition for progressive fish gathering is that the side reflectors 5 form a light beam with a large illumination range and proper illumination intensity, the light beam enables the metal halide lamp 2 not to quickly skip the sea surface in the swinging process, and a gradual change process exists, and the process enables the fish in the illumination range to have enough time to move to the vicinity of the fishing boat along with the light of the metal halide lamp 2. Therefore, in order to realize the gradual fish gathering, the swing driving device and the side reflector 5 complement each other, but none of them is necessary.

As shown in fig. 12 and 13, when the telescopic driving means 4 performs telescopic movement, the rod-shaped metal halide lamp 2 can be tilted in a stepwise or stepless manner about the rotation shaft 11 provided in the horizontal direction toward or away from the fishing boat. The stepped swing usually requires a brushless motor as the motor 43 of the telescopic driving device 4, the driving mode of the brushless motor is complex, and the corresponding lamp attitude control device is high, but the control precision is good, and a complex and precise motion mode can be realized.

In the process of gradually gathering fish, all the metal halogen lamps 2 on the fishing boat can synchronously move together and obliquely swing, and can also be segmented, and the metal halogen lamps 2 in each segment synchronously obliquely swing together. As described above, the distance of the light emitted from the halogen lamp 2 to the ocean surface gradually approaches the fishing boat from far to near, and the light may stay at several angles, i.e., several distances therebetween. The effect of the stay is to allow sufficient time for the fish to catch up with the illuminated area of the metal halide lamp.

The embodiment of the invention also comprises a progressive fish gathering method which is realized by adopting the swing type fish gathering lamp, and in the progressive fish gathering process, the swing of each metal halide lamp 2 is controlled by a control system, so that the illumination range of each metal halide lamp 2 moves from far to near on the sea surface.

While the present invention has been described in detail and with reference to the embodiments thereof as illustrated in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments are not to be interpreted as limiting, and the scope of the invention is to be determined by the appended claims.
