Underwater plant growth lamp

Abstract

The invention discloses an underwater plant growth lamp. The underwater plant growth lamp comprises an overwater part and an underwater part, wherein the overwater part comprises a floating body and electric propellers which drive the floating body to walk in four direction of left, right, front and rear; the underwater part comprises an air cylinder having a waterproof effect and a globular lamp,wherein a lamp holder is fixed to an end of a telescopic rod of the air cylinder, and a waterproof corrugated cover which is arranged outside the telescopic rod in a sleeving manner is connected between the cylinder body of the air cylinder and the lamp holder; and a groove is formed in the bottom of the lamp holder, a rotating body is fixed in the groove through a rotating shaft, one end of therotating shaft is fixed on the wall of the groove through a bearing seat, a miniature servo motor is fixed to the other end threading out of the other side wall of the groove, of the rotating shaft, and the globular lamp is fixedly connected to one side wall of the rotating body. The overwater part drives the underwater part to positions of aquatic plants, so that the diminishing effects of reflection, scattering and the like of particulate matter in water on light sources can be reduced, and the growth of subaquatic plants can be effectively promoted.

Description

technical field [0001] The invention relates to a lamp, in particular to an underwater plant growth lamp, which belongs to the technical field of lamp preparation. Background technique [0002] Plant growth lamp is a special kind of lamp. It uses the principle of sunlight to provide the environment for plant growth and development by using light instead of sunlight. It can effectively save resources and improve the ecological environment. However, the plant growth lamps in the prior art are not suitable for underwater plant growth. One is because of the special underwater environment, this plant growth lamp must have a strong waterproof effect, and the existing ones cannot do so. The second is that the suspended particles in the water will hinder the irradiation of light in the water body, and the existing methods are all fixed, which affects its use effect. Contents of the invention [0003] In view of the deficiencies in the prior art above, the purpose of the present i...
