Refractive means (25) having elastic restoring force and longitudinally connecting the upper body (20) mounted on the upper end and the central body (30) in the lower direction, the buoy (50) is coupled to the upper and through the lower part (42) by forming a lower main body 40 to be operated up and down by the sea water while the central body is in sliding contact with the longitudinal direction, and a chain 65 connecting the lower weight 60 of the lower body It is composed.
Alternatively, the refractive means 25 of the present invention is preferably composed of a spring having an elastic restoring force.
Or the present invention preferably further comprises a roller 35 for reducing the friction between the central body 20 and the lower body 40.
The above is described in more detail as follows.
First, the illuminator 10 is a conventional lighting device that can use sunlight as already known is a flange is formed at the bottom.
The upper body 20 to form a flange 22 on the top so that the brightener 10 is assembled by a bolt and nut, etc., as well as to facilitate later maintenance.
The upper body 20 and the central body 30 are connected in a straight line by the refraction means 25 in a longitudinal direction, and form coupling portions 24 and 32 at ends connected to the refraction means.
When the refraction means 25 is applied to the upper body 20, the impact force is elastically deformed while flexibly deformed to absorb the impact force and to restore to its original configuration, consisting of a coil spring or a leaf spring, etc., in addition to the various members It may be.
The lower body 40 is configured so that the central body and the upper body can be expanded and contracted by sliding the center body is inserted into the open upper end.
Here, the present invention is a configuration further provided with a roller 35 for reducing the friction force between the central body 30 and the lower body 40.
This minimizes the frictional force during telescopic operation by mounting the rollers 35 on the upper part of the lower body, and as shown in FIG. It is preferable to install radially.
The roller 35 is preferably configured to support the support body attached to the lower body and to contact the central body through the opening hole of the predetermined lower body.
In addition, buoy 50 is coupled to the upper portion of the lower body 40, buoyancy acts by the sea water 80, the bottom is formed at least one or more through holes 42 to the sea water enters. The chain 65 is connected to the lower end of the lower body by forming a connection ring 44.
