Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, the present embodiment provides a kind of and touches end self start type bed material sampling thief, comprises sampling storehouse 1, counterweight cabin 2, web member 3 and unidirectional slide mechanism 4; Wherein, described counterweight cabin 2 is arranged on top, described sampling storehouse 1, and lower end, described sampling storehouse 1 has opening 5, and described unidirectional slide mechanism 4 uses described web member 3 to tilt to be fixed on side, described sampling storehouse 1; Described unidirectional slide mechanism 4 inclined sliding covers on the opening 5 in described sampling storehouse 1.
Described in the present embodiment, unidirectional slide mechanism 4 comprises back up pad 41, sliding panel 42, slide block 43 and angle fixed head 44; Described back up pad 41 tilts to be fixed on described web member 3, described sliding panel 42 is set in parallel in above described back up pad 41, toothrow 6 in a row is provided with along a described back up pad 41 length direction first-class spacing in side relative with described sliding panel 42, on the side that described sliding panel 42 length direction is relative with described back up pad 41, corresponding described toothrow 6 is equally spaced is provided with latch 7 in a row, on the unidirectional toothrow 6 being fastened on described back up pad 41 of the latch 7 on described sliding panel 42; Described slide block 43 is fixedly installed on the end of described sliding panel 42; Described angle fixed head 44 be arranged in parallel with described sliding panel 42, and is slidably connected between described angle fixed head 44 and described sliding panel 42; Described sliding panel 42 inclined sliding covers on the opening 5 in described sampling storehouse 1.
Balancing weight (not shown) is accommodated in described counterweight cabin 2.
Dividing plate (not shown) is provided with between described counterweight cabin 2 and described sampling storehouse 1.
Also comprise the first rope 8 and the second rope 9, described first rope 8 one end is fixed on described counterweight cabin 2, and the other end extends upward the water surface; Described second rope 9 one end is fixed on described unidirectional slide mechanism 4 and (it should be added that second rope 9 one end can be fixed on slide block 43, also can be fixed on described sliding panel 42), the other end ties up on described first rope 8 and forms a knot point 10.
Described second rope 9 one end is less than the length of described first rope 8 one end to knot point 10 to the length of knot point 10.
For describing the utility model in detail, expanding now and being described as follows:
During the sampling thief testing that the utility model provides, be connected to by this sampling thief on crane rope of hydrographic winch, rope is all in tight state everywhere under a stretching force, and the sliding panel 42 on right side is suspended in whole sampling thief upper right side by rope; Lifting sampling thief; Then sampling thief is transferred, insert under being allowed to condition at self-gravity action in river sediment, when sampling thief is motionless in silt, the pulling force of sampling storehouse 1 epimere first rope 8 disappears, continue to transfer rope, then the toothrow 6 of the sliding panel 42 of right-hand member just along unidirectional engaging under gravity and inertial force effect glides step by step, is finally stuck in last row toothrow 6 place, and sampling storehouse 1 opening is also closed simultaneously.When sampling thief is carried, drop to minimum due to slide plate 42 place and blocked by toothrow 6, so the second rope 9 interface of slide plate is nearer to the distance of the knot point 10 of two ropes than sampling storehouse 1 first rope 8 interface to the distance of the knot point 10 of two ropes in top, when more than carrying, the first rope 8 sampled on storehouse can't accept power, only have on sliding panel 42 stressed, so whole instrument is carried.Take out the silt sample in sampling storehouse after leaving the water, carry out drying, weighing and grain composition analysis.
The sampling thief that the present embodiment provides adopts and touches end self start type switch, and reliability is higher, and less to the state of nature disturbance of bed material; Can conveniently add loss of weight amount, can adapt to different flow conditions, accommodation is wider.From development theory and sampling thief basic structure, sampling thief can be used for bed material test and the unit dry weight test of other reservoir, lake, neritic zone etc.From application target, the safety case of the pollution condition of river bed, upstream water and soil wastage and assessment downstream water conservancy projects can be judged by the bed material of sampling.
Sample storehouse 1 cross-sectional area described in the present embodiment little, pressure is large, reduces silt to the impact of instrument, meanwhile, less to the state of nature disturbance of bed material, improves sampling precision.In addition, utilize the control that a rope is divided into two sections, the spontaneous object in the tactile end can be arrived, utilize equilibrium of forces principle to control the opening and closing of sliding panel 42, decrease the impact of artificial operation factors, improve work efficiency.
Above-described embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only embodiment of the present utility model; and be not used in restriction protection domain of the present utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
