Abstract
The utility model relates to an optical observing device used to observe the condition of living things and the distribution of remaining bait on the bottom of an aquatic cultivation pool, comprising a long observing tube, telescope lens, an observing window arranged on the lower end of the observing tube, and a light source used to illuminate the bottom of a pool. The utility model with the advantages of simple structure, low cost, lightness, and convenient operation can be used to observe the bottom of a pool under the deep water by using naked eyes directly, and is suitable for culturists of aquatic products, particularly for culturists of prawns.
Description
The utility model relates in a kind of aquaculture, particularly prawn culturing, is used for the observation utensil of distribution of claire ledger bait material and biological situation.
At present, in aquaculture, particularly in the prawn culturing, owing to can't remain situation and biological situation by claire ledger bait material, throwing in the bait band bears the character of much blindness, not only waste a large amount of bait, improve aquaculture cost, and unnecessary bait rots at the bottom of the pond, pollute at the bottom of the pond, cause the bait disease, even the anoxic floating head, endanger very big.
It is a kind of simple in structure that the purpose of this utility model is to provide, and cost is low, at the bottom of the direct claire of energy, and viewer at the bottom of the pond that suitable raiser uses.
Technical solution of the present utility model is, utilize optical principle, take directly to detect by an unaided eye structure at the bottom of the pond promptly is equipped with telephoto lens in the upper end of airtight long inspection section, is provided with transparent watch window in the lower end of inspection section and is used to illuminate the light source of bottom surface, pond.
When the utility model uses, aboard ship watch window is inserted at the bottom of the pond from the water surface by inspection section, be about 20 centimeters away from bottom surface, pond, connect light source and illuminate at the bottom of with the pond, then can directly clearly observe residual bait and the biological situation on the bottom surface, pond of culturing by telephoto lens.
Advantage of the present utility model is that owing to taked airtight observation window structure to be installed in the inspection section bottom, light source is in observation window, shine near the bottom surface, pond, therefore, do power supply, at the bottom of doing light source enough illumination claire can be provided with bulb with general dry battery; Eyepiece adopts telephoto lens, and focal length is adjustable at any time, can adapt to bottom surface, rugged pond, make the utlity model has simple in structure, cost is low, and is light and handy, easy to use, can clearly observe situation at the bottom of the pond, be fit to very much professional raising farmer, particularly prawn culturing specialist and use.Remain situation and prawn decortication situation according to pond ledger bait material, adjust the bait injected volume at any time, the one, can prevent the bait waste effectively, can save bait 15~20%, the 2nd, can avoid bait to rot to pollute Chi Shui, cause disease and anoxic floating head phenomenon.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.In the present embodiment, inspection section 8 is to make with rigid plastics or fiberglass, getting single-unit or more piece according to the degree of depth of Chi Shui is tightly connected and forms, present embodiment adopts two joints, and upward joint 8b is a cylinder barrel shaped, and following joint 8a is taper barrel plastics inspection sections, and its lower end bore expands to 25cm, up and down between two joints by being threaded, and rubber seal sealing.The telephoto lens 9 of the adjustable focal length of being made up of one group of lens is installed in the top of inspection section 8 by screw thread.For present embodiment easy to use is provided with top 8c in the inspection section upper end, telephoto lens 9 is threaded with top 8c, and top 8c is threaded with the joint 8b that goes up of inspection section, also can be threaded with following joint 8a, when pond water is shallow, can take off going up joint 8b, top 8c directly is connected use with following joint 8a.For easy to operate, battery case 11 is installed in the side of the top 8c of inspection section 8, six joint dry cells are housed, be provided with switch 10, electric wire respectively saves the junction to what bottom and light source 4 were connected inspection section 8 down along the inwall of inspection section, be provided with electric wire and connect contact, when two joint screw sockets were tightened, electric wire was dynamically connected certainly by contact.The observation window structure that is installed on inspection section 8 bottoms as shown in FIG., be fixedly mounted on the lower end of inspection section 8 by Plastic Welding with plastic observation window shell 5, observation window end cap 2 is to make with lucite, be threaded with shell 5, carry out sealing with rubber seal 3, the observation window clear glass is embedded on the watch window 1 on the end cap 2, and implementation sealing, reflection shield 6 is to be pressed abd fixed in the observation window by end cap 2, light source 4 is made up of 3 2.5 volts of small electric bulbs, is installed in the inboard of reflection shield 6 with distributing.Observation window of the present utility model, taked the structure that enlarges by shell 5, reflection shield 6 is abducent cone ports from the inspection section lower port, this structure can not only guarantee that watch window has the enough big visual field, the light that light source sends does not reach camera lens, do not influence observation, and the light that light source sends all reflexes to observed ground, help improving observing effect.Be damaged or pollute in order to prevent that watch window glass from contacting to earth in operation, be provided with the back-up ring 13 of projection at the periphery of end cap 2 front ends, balance weight body 7 is the cast iron rings that are sleeved on the inspection section lower end, is for offsetting water the buoyancy of viewer to be convenient to operation setting.12 for being the button or the hook of drag rope among the figure, and the other end system of rope aboard ship draws when being convenient to mobile operating.
