Description

TECHNICAL FIELD

[0001] The utility model relates to a lamp, especially in a kind of improved underwater fish collecting lamp. BACKGROUND

[0002] Fish collecting lamp is one of important tools in present fishery, and has important key factor to fish catch. Underwater fish collecting lamp is suitable for various fishery operating environments, including but not limited to aquaculture fishing ground, ocean fishing, river and lake night fishing and the like. Generally, underwater fish collecting lamp has large power, and the size of radiator is also large. Since fishery production working condition is special, underwater fish collecting lamp often works in sea surge and ship shaking, so it must have good shockproof and waterproof performance. Especially, underwater fish collecting lamp power supply line is shaken due to surge and ship shaking, and then power supply line is prone to form leakage to make seawater flow into fish collecting lamp and damage it, especially the deeper the water is, the greater the water pressure is. At this time, shaking forms large force pulling to power supply line inlet end of underwater fish collecting lamp, so that power supply line inlet end of underwater fish collecting lamp is loose and leaks, and finally the service life of underwater fish collecting lamp is short. For example, Chinese patent document CN201721005168.7 discloses an overheating protection underwater fish collecting lamp, which relates to underwater fish collecting lamp, and comprises lamp body, lamp column cylinder arranged in the lamp body, control box and cable seat. Waterproof connector is arranged above the lamp body top cover, and the cable seat is provided with power supply line, waterproof inlet and plug. The waterproof connector is connected with the waterproof inlet, and the control box is provided with anti-interference circuit board, leakage switch and socket. The plug is inserted into the socket. Compared with prior art, the lamp body is locked with the power supply line to avoid water leakage of the power supply line and penetration into the lamp body. The product has simple external control, leakage protection switch and common mode anti-interference circuit control box, which can not interfere with other ship equipment, prevent lightning and electric shock. Although the waterproof inlet is arranged, the power supply line inlet is pulled by large force due to shaking when the underwater depth is several tens of meters or more, so that the power supply line inlet is loose and leaks, and the service life is short. SUMMARY

[0003] Therefore, aiming at the above problems, the utility model provides an improved underwater fish collecting lamp with novel structure, convenient use, good waterproof performance of power supply line inlet and long service life.

[0004] To solve the technical problem, the utility model discloses the following scheme: A improved underwater fish collecting lamp, including the lamp body and control box, be equipped with the lamp post cylinder in the lamp body, the waterproof wire entry structure is equipped at the wire inlet of lamp body top cap, waterproof wire entry structure includes first cable seal waterproof joint, second cable seal waterproof joint and hollow waterproof post, waterproof post lower part is equipped with the cavity of containing first cable seal waterproof joint and waterproof post upper part is equipped with the connecting port sealed connection with second cable seal waterproof joint, first cable seal waterproof joint sealed wear is in the wire inlet of lamp body top cap, waterproof post lower part cover is equipped on first cable seal waterproof joint and waterproof post bottom end and top cap surface sealed fixed connection, second cable seal waterproof joint sealed wear is in the connecting port of waterproof post upper part, and the power cord of control box output passes through second cable seal waterproof joint again and then passes through waterproof post upper part and then passes through first cable seal waterproof joint and then enters the lamp panel electric connection of lamp body and lamp post cylinder with control box control lamp panel lighting and closing.

[0005] Further improvement, the first cable seal waterproof joint and second cable seal waterproof joint are any one of explosion-proof gland, metal cable waterproof joint, armored explosion-proof joint, explosion-proof sealing joint.

[0006] Further improvement, the waterproof post bottom extends outward to form a positioning periphery, the waterproof post is fixedly connected with the top cover through the positioning periphery, and a waterproof sealing rubber layer is arranged on the locking gap between the waterproof post and the top cover.

[0007] By adopting the foregoing technical scheme, the utility model has the advantages that the waterproof wire entry structure is newly designed, that is, a multi-sealing structure with stable structure is formed by the first cable seal waterproof joint, the second cable seal waterproof joint and the hollow waterproof post, the first cable seal waterproof joint is covered by the waterproof post, and the second cable seal waterproof joint is fixedly connected to the waterproof post, so that the stress at the positioning and fastening positions of the first cable seal waterproof joint and the second cable seal waterproof joint is different, the fish collecting lamp of the utility model only shakes the second cable seal waterproof joint when it shakes under water for dozens of meters or more, even if the second cable seal waterproof joint leaks, the first cable seal waterproof joint still seals and protects the power cord, the power cord is segmented by the waterproof post and the second cable seal waterproof joint to eliminate the influence of the shaking pulling force on the first cable seal waterproof joint, the waterproof wire entry structure of the fish collecting lamp is effectively prevented from being pulled by a large force from the side to cause loosening and water leakage, the structure is novel, convenient to use, good in waterproof performance of the power cord, long in service life, and can be widely applied.
