One height.
The present apparatus is placed at current water to be sampled by the present invention when specifically used, and fixed plate 20 is passed through branch
Leg or or be fixed in riverbed or waterfront, so that the multiple sampling bottles 2 of turntable 7 i.e. below is located at the water surface hereinafter, under impeller 17
Portion also is located at the water surface hereinafter, lever 10 and water tank 15 are located at the water surface or more, while will be packed into water in water tank 15, and water surface elevation is overflowing
28 position of discharge orifice.
The course of work of the present apparatus is introduced for convenience, the circumferential direction of roller is divided into three positions herein, from cylinder wall
Upper quadrant point start, be followed successively by a position, two positions and three positions, 120 degree of each position span along clockwise direction.
When original state, the notch 9 on turntable 7 is located in the interval of two vertical bars 5 not with any one vertical bar 5 relatively,
Vertical bars 5 all at this time are depressed by turntable 7, and the first conical plug 4, which stoppers sampling bottle 2, prevents it from intaking；Dust-collecting bucket 11
For empty barrel, block of breeding at this time is located at left end position and contacts with nut 25, and the torque of 10 left end of lever is greater than the torque of right end, thick stick
The left end of bar 10 is low, and dust-collecting bucket 11 is in a vertical state under gravity.
After device places, the water in water tank 15 is flowed into the dust-collecting bucket 11 of lower section through apopore 16, works as dust-collecting bucket
When water in 11 is more and more, the gravity of water is increasing in dust-collecting bucket 11, and the torque of 10 right end of lever is increasing, works as lever
When the torque of 10 right ends is greater than the torque of left end, lever 10 can be rotated clockwise, and left end increases, and right end reduces, when left end is higher than
When right end, breeding block can slide into the right the position contacted with limit plate 26, shorten the arm of force of 10 left end of lever, torque subtracts
It is small；As lever 10 continues to rotate, the lower end of dust-collecting bucket 11 can contact fixed plate 20, and 10 right end of lever, which continues to move down, can make to catchment
Bucket 11 is toppled over to side, and idler wheel 24 reduces the resistance of lower end when dust-collecting bucket 11 is toppled over rolling in fixed plate 20, until dust-collecting bucket
11 side wall is poured over completely in fixed plate 20, and the water in dust-collecting bucket 11 can be poured out in the process, the collection after pouring out water completely
11 empty barrel of bucket reduces the torque of 10 right end of lever, and 10 left end clump weight 12 of lever is bigger to the torque of 10 left end of lever at this time
In empty barrel to the torque of 10 right end of lever, lever 10 can be rotated counterclockwise just, when turning to left end lower than right end, clump weight 12 to
A left side slides into be contacted with nut 25, until 10 left end of lever drops to extreme lower position, dust-collecting bucket 11 returns to extreme higher position, entire to fill
Put back into multiple original state.
During above-mentioned lever 10 rotates clockwise, fixing axle 13 on lever 10 drives the by freewheel clutch
The rotation of one bevel gear 8, first bevel gear 8 drive turntable 7 to rotate by second bevel gear 14, the angle etc. that turntable 7 rotates every time
Angle between two neighboring sampling bottle 2, in 7 rotation process of turntable, notch 9 thereon can pass through a sampling bottle 2, lack
When mouth 9 is by sampling bottle 2, the vertical bar 5 of 2 top of sampling bottle moves up under the action of the first pressure spring 6, drives the first conical plug 4
It is extracted from the bottleneck of the sampling bottle 2, which opens, and river water pours into the sampling bottle 2, and the side of subsequent notch 9 can will erect
Bar 5 gradually pushes, and seals conical plug beyond the Great Wall the sampling bottle 2 for filling water, and notch 9 rests between next sampling bottle 2
In interval；When lever 10 rotates counterclockwise, fixing axle 13 does not drive first bevel gear 8 to rotate.
When the water in dust-collecting bucket 11 reaches above-mentioned amount again, lever 10 drives turntable 7 to rotate once again, herein mistake
Next sampling bottle 2 opens sampling in journey, is then shut off；Since the water surface in water tank 15 is constant, the constant magnitude of apopore 16,
Therefore water outlet constant airspeed, i.e. lever 10 are constant per the time interval between rotation twice, realize that the timing of turntable 7 turns with this
It is dynamic, 2 timing sampling of sampling bottle.
When needing to adjust sampling interval, two methods can be used, first method is to adjust second by bolt 23
The height of conical plug 21, is adjusted up, and the gap between the second conical plug 21 and apopore 16 becomes larger, and water speed becomes faster out, rolling
The time interval of cylinder rotation reduces, and the time interval of sampling reduces, and adjusts downwards then between the second conical plug 21 and apopore 16
Gap become smaller, water outlet slows, and the time interval of roller rotation increases, and the time interval of sampling increases；Second method
Be by the position of screw plug adjusting nut 25, to tune up the time interval of sampling, then screw on nut 25 to the left, then original state
Under the position of breeding block more keep left, longer to the arm of force of 10 left end of lever, torque is bigger, therefore needs to receive in dust-collecting bucket 11
Collecting more water just can be such that lever 10 rotates, and inlet time is elongated, therefore sampling interval increases；On the contrary, if to turn sampling down
Time interval, then screw on nut 25 to the right, then the position of the breeding block under original state is more kept right, to 10 left end of lever
The arm of force it is shorter, torque is smaller, thus need to collect in dust-collecting bucket 11 less more water can make lever 10 rotate, when catchmenting
Between shorten, therefore sampling interval reduce；Above two structures and methods are desirable first, also may be used in combination.
It should be noted that the torque difference of the left and right ends for promoting lever to rotate clockwise described above need to be by the second cone
Resistance when gear rotates is taken into account.
The present invention utilizes the impact force of water flow, is pumped water in water tank 15 by impeller 17, converts the kinetic energy of water flow to
Potential energy, then drive the rotation of turntable 7 to carry out interval sampling the kinetic energy that potential energy is lever 10, power supply or energy storage member is substituted
Part can continue ceaselessly to provide power, the risk of no waterlogged damage, and pole is suitable for water environment；It is carried out by water velocity
Periodically, as long as water flow is not stopped, so that it may continue uninterrupted timing timing, operating time is unrestricted；In addition, passing through adjusting
The speed of water outflow in water tank 15, or the clamping force of fixture block is adjusted, it is fixed that any stepless adjusting can be achieved in two ways
When time interval, and adjustment structure is simple and reliable, adjusts very convenient.
To sum up, the present invention is a kind of for current water, and no electrification does not fear water, can any control interval duration, when energy is long
Between the timing sampling device that continues working.
