Abstract
The utility model provides a sludge sampler which utilizes the gravity of the sludge sampler to sample bottom materials in deep water. The utility model is composed of a sludge sampling pipe, a main body and gravity rings, a valve and a controller, a sealing ring, etc. and is characterized in that the sludge sampling pipe is a straight pipe with a thin wall; the main body is in a straight cylinder shape, the sludge sampling pipe can be inserted into the inner diameter of the main body, and a plurality of gravity rings and flanges are arranged on the outer diameter at the upper end of the main body in sequence; screw nails are arranged on the flanges to be connected with the wall of the main body in a thick mode, and screw bolts are also arranged on the flanges to connect the gravity rings and the body into integration; an outlet at the central hole of the main body is provided with a valve. When the valve opens, the sludge sampling pipe is sunk into water to. When the sludge sampling pipe contacts bottom sludge, the valve automatically closes. The sampling process is completed for one time with the sludge sampling pipe extracted.
Description
The utility model relates to the open-air bottom sampler of sampling under water, particularly a kind of profundal zone gravity bottom sampler that is applicable to 10 meters following depth of waters.
Taking of sediment sample is an important step of sediment analysis work, and for adopting mud greater than the profundal zone of 10 meters depth of waters, owing to be difficult to the transmission of realizable force, general bottom sampler can't use.Present domestic no deep water is adopted the approved product of mud, and the user uses and to be the nonstandard product of self-control, and structure is unreasonable, processing is coarse, undesirable in the practical application, and efficient is low.
The purpose of this utility model provides a kind of bottom sampler of taking by bottom sampler gravity realization deep water substrate, can be made into the standard approved product and uses for the user
Structure of the present utility model is by adopting the mud pipe, main body and gravisphere, formations such as valve and control device and O-ring seal, it is characterized in that adopting mud Guan Weiyi section thin-walled straight tube, main body is a straight-tube shape, internal diameter inserts for adopting the mud pipe, upwards be provided with several gravispheres and ring flange successively on the external diameter of main body upper end, establishing screw on the ring flange connects with the main body wall thickness, also being provided with bolt on the ring flange is connected as one gravisphere and main body, adopting the mud pipe connects with subject activity, in exit under the main center hole and adopt between the mud external diameter of pipe and be provided with oil sealing, the hole upper outlet is provided with valve in main center, and be provided with oil sealing, be with the hole on the crossbeam that passes a door shaped stent behind the spring on the vertical valve rod that combines as a whole with valve, the aperture is greater than the valve rod external diameter, door shaped stent is connected on the ring flange, also upwards vertically connect a little door shaped stent on this door shaped stent crossbeam, the crossbeam of this support is a hinging supporting shaft.Movablely on the hinging supporting shaft connect a triangle suspension hook that is shaped as the buckle pawl, leg-of-mutton to go up the summit be suspension eye, and left summit is hinging supporting shaft and hook, and right summit is a balancing weight, and suspension eye center and valve rod and main body, to adopt mud tube hub axis consistent.Adopt between mud pipe and the main body and connect for the clamp activity.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model general illustration (a valve gap opening);
Fig. 2 closes synoptic diagram for valve gap;
Fig. 3 is the side view of Fig. 1.
With reference to figure 1-3, to adopt mud pipe 5 and adopt the organic glass removable jew, every length is 1 meter, can carry out encapsulation, the transportation of sample easily.Because organic glass has the transparency, the sedimentary section of sample in the observation tube clearly.The loading and unloading of adopting the mud pipe are very easy, in the bottom of bottom sampler main body 13, a trip bolt 6 arranged, and adjust this screw and can make the clamp of fixedly adopting the mud pipe unclamp or entreat tight.
Packoff is made of two rubber oil seas up and down, and when adopting the mud pipe and insert the bottom sampler main body, there is a rubber oil sea 14 below and adopts the mud external diameter of pipe and cooperate in the main body; When the valve 8 at main body top is closed, valve under the effect of stage clip 11 with main body above rubber oil sea 12 closely cooperate, adopt the cavity that forms a sealing in the mud pipe, stop water and air to enter, prevent that the mud sample of adopting in the pipe from coming off.
Valve and control system are by hook 3, and suspension hook rotating shaft 2, valve 8, valve lever 9, balancing weight 10 and stage clip 11 constitute.With having handed up valve and tangle the upper edge with suspension hook, mention wire rope 1, because suspension hook rotating shaft 2 integral central line relatively, suspension hook will firmly hook valve and make it be in opening under action of gravity.Insert bed mud when adopting the mud pipe, when bottom sampler gravity fades away, because two balancing weights 10 are equipped with at the suspension hook rear portion, make rotating shaft 2 center line right sides overweight the left side greatly, suspension hook will lift automatically, and valve enters closed condition under the effect of stage clip, and the inclined-plane and the rubber oil sea of valve bottom are combined closely.
Gravisphere 4 is installed on the main body outside by two screw rods 7, according to the laxity of substrate under water, can suitably increase and decrease gravisphere, thereby regulate sampling depth.This bottom sampler precision machining, rational in infrastructure, firm and durable is used reliably, and 15 for being connected in the door shaped stent on the ring flange door, and 16 for being connected in the little door shaped stent on 15.
Method of operating of the present utility model is as follows:
1. will adopt mud pipe 5 and insert, and tighten 6 lockings of clamp screw and adopt the mud pipe from main body 13 bottoms;
2. the wire rope with winch for ship is connected with suspension eye on the bottom sampler valve suspension hook, opens the valve 8 on main body top, and the valve suspension hook is hooked valve, mentions wire rope 1, makes valve be in opening.Bottom sampler is vertically put into water, start at full speed winch sinking bottom sampler, water enters from valve and discharges from adopting mud pipe bottom.When adopting the mud pipe and touch bed mud, under action of gravity, to adopt the mud pipe and will insert bed mud and reach balance until gravity, this moment, valve was closed under spring 11 effects automatically;
3. oppositely start winch and mention bottom sampler, unclamp the clamp screw, transfer to and adopt the mud pipe, seal the plexi-glass tubular two ends, promptly finish once sampling.
The utility model is that a kind of convenient and reliable deep water is adopted mud sample instrument, and is rational in infrastructure, and firm and durable is easy to carry, and the open-air deep water sampling in the fields such as geology, environmental protection, water conservancy, lake, ocean that are applicable to can be made into the standard approved product and uses for the user.
