Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, a kind of deep-water sludge sampler provided by the invention, comprise stopple coupon 1, piston 2, pull bar 3, handle 4, closing plug 5, bottom cover 6, top closure 7 and capping pull bar 8, piston 2 fits tightly in stopple coupon 1, piston 2 is connected with pull bar 3, handle 4 is arranged on the top of pull bar 3, top closure 7 and bottom cover 6 are located at top and the bottom of stopple coupon 1 respectively, top closure 7 is connected by capping pull bar 8 in the outside of stopple coupon 1 with bottom cover 6, closing plug 5 is located at one end of bottom cover 6, and closing plug 5 coordinates with bottom cover 6, by the connection function of capping pull bar 8, make stopple coupon 1 be communicated with two cappings and form entirety, the inwall of stopple coupon 1 fits tightly piston 2, piston 2 is pulled to move at stopple coupon 1 inwall by the effect of pull bar 3, utilize stopple coupon 1 inner carrier both sides pressure difference, thus absorption bottom silt.
Sludge sampler of the present invention, the material of its stopple coupon 1 is fiberglass, the wall thickness of stopple coupon 1 is 5mm, internal diameter is 50mm, and external diameter is 60mm, and long is 500mm, verify through case history, such dimensions has practical operation and is worth, and gets mud effect better, sufficient mud can be taked to analyze for deep water.
As shown in Figure 1, piston 2 fits tightly with the inwall of stopple coupon 1, stopple coupon 1 is divided into two chambeies by piston 2, and the material of this piston 2 is rubber, when carrying out mud sampling operation, only pull bar 3 need be pulled, due to pressure change in stopple coupon 1 cavity of piston 2 both sides, mud is sucked in stopple coupon 1 chamber, obtains mud sample in deep water smoothly.
As shown in Figure 1, pull bar 3 is stainless steel with the material of handle 4, one end that pull bar 3 is connected with piston 2 has screw thread, the other end connects handle 4, handle 4 and pull bar 3 form T-type structure, in the present embodiment, pull bar 3 is locked at pull bar 3 end mounting nuts through after the through hole in the middle of piston 2, pull bar 3 and piston 2 are fastenedly connected, there is enough tensile strength simultaneously, meet piston 2 stressing conditions when pulled when sampling, it should be noted that, in the present embodiment, the diameter of pull bar 3 is slightly less than the through-hole diameter of piston 2, pull bar 3 can be made to pass through piston 2.In concrete enforcement, can open non through hole in the middle of piston 2, the non through hole inside of piston 2 opens screw thread and pull bar 3 end is threaded connection, and forms firm annexation, and it also can be integrated member that pull bar 3 and handle 4 can assembledly be connected.
As shown in Figure 1, capping pull bar 8 is two pieces, is symmetrically set in the both sides outside stopple coupon 1 wall respectively, makes capping annexation more stable, reaches better plugging effect, and the mode that symmetry is arranged in both sides make stressed evenly.
As shown in Figure 1, the edge of top closure 7 and bottom cover 6 is all corresponding has the first through hole, capping pull bar 8 is through corresponding first through hole on top closure 7 and bottom cover 6, the two ends attaching nut of capping pull bar 8, the relative position of capping pull bar 8 with bottom cover 6 is fixed by the nut wherein near one end of bottom cover 6, nut near top closure 7 one end adopts wing nut, can regulate fixing relative position, to reach better plugging effect.When sampler gets mud, by the nut screwing clamping at capping pull bar 8 two ends, position need be fixed and samples again.
As shown in Figure 1, top closure 7 center has the second through hole, pull bar 3 is through the second through hole, stretch to outside the chamber of stopple coupon 1, connect handle 4, be convenient to better operate pull bar 3, carry out the sampling of mud, bottom cover 6 center has third through-hole, third through-hole and closing plug 5 closely cooperate, the sampling end of stopple coupon 1 is made to form good plugging effect, during concrete operations, when needs carry out deep-water sludge sampling, closing plug 5 is pulled away bottom cover 6, pull out handle 4 to sample, after having sampled, closing plug 5 is installed, the mud sample of sampling is made to be enclosed in stopple coupon 1, band backwater surface is analyzed.
In the present invention, the material of bottom cover 6 and top closure 7 is hard rubber, for the two ends of closed stopple coupon, adopts hard rubber, and greatly, corrosion-resistant, cost is low for hardness and intensity.
The material of closing plug 5 is poly-polypropylene fibre, and is connected with cotton rope between closing plug 5 and stopple coupon 1, and when specifically implementing, the wire rope handling that can punch on closing plug 5 lies on stopple coupon, in case drop when opening closing plug 5.
It should be noted that, in bottom cover 6, third through-hole of opening is thief hole, for the ease of the smooth sampling of mud, under the prerequisite met the demands, the diameter of this third through-hole needs large as far as possible, when this diameter is tending towards suitable with stopple coupon internal diameter, more convenient mud sampling, sampling efficiency is higher.
In sum, a kind of deep-water sludge sampler provided by the invention, principle is reliable, structure is simple, be convenient for carrying, be convenient to dismounting and adjustment, selection is simultaneously reasonable, indeformable impaired under can resisting the effect of deepwater regions hydraulic pressure, solve the problem not having special deep-water sludge sampler, ensure that underwater construction is carried out smoothly.
Below be only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
