in this embodiment, the hook 8 is fixed on the top end of the support rod 6.
Adopt above-mentioned scheme:
when the silt in the river channel needs to be sampled, the device can be placed right above a sampling point, so that the silt freely falls into river water and sinks under the influence of gravity and buoyancy of the water (at the moment, a steel wire rope is in a loose state), and in the sinking process of the device, the river water can flow out of the inner shell 1 through the first water changing port 3, so that the phenomenon that the stability of the device during sinking is influenced due to the backflow of the river water in the accommodating cavity is avoided; after the bottom of the inner shell 1 is contacted with silt, under the action of inertia, the inner shell 1 is quickly inserted into the silt, the flowing water impacts the baffle 2 to enable the baffle 2 to swing upwards and open an opening in the bottom of the inner shell 1 when the baffle sinks, meanwhile, each baffle 2 further swings upwards until the baffle is abutted to each limiting block 4 due to the upward impact force of the silt, the opening in the bottom of the inner shell 1 is opened to the maximum extent at the moment, the silt is extruded into a containing cavity from the opening in the bottom of the inner shell 1, and the original water in the containing cavity of the inner shell 1 is discharged through the first water changing port 3; because the limit block 4 limits the swing of the baffle 2, the baffle 2 and the inner wall always have a certain angle, when the collected silt needs to be recovered, the steel wire rope is pulled upwards to drive the inner shell 1 to ascend, and under the action that part of the silt impacts the baffle 2 downwards and the dead weight of the baffle 2, the baffle 2 swings downwards until the baffle abuts against the supporting step 5 to seal the opening at the bottom of the inner shell 1, so that the silt is prevented from further leaking and the collected silt is collected at the same time; after this device pulled out the surface of water, the staff can open the opening of inner shell 1 bottom through upwards promoting baffle 2, pours silt.
Further, it is shown with fig. 4 to combine fig. 3, be equipped with vertical spout 9 on the 1 lateral wall of inner shell, the cover is equipped with the shell 10 with the central line on the 1 outer wall of inner shell, the connecting piece has set firmly on the 10 lateral walls of shell, the connecting piece passes spout 9 and is connected with stopper 4, when this device need be withdrawed from the bottom, through setting up conventional hoist engine rolling wire rope and drive inner shell 1 and rise, at this moment, baffle 2 is whole also for stopper 4 rebound, stopper 4 and 2 relative sliding of baffle are until inconsistent with support step 5 with 2 lower pendulums of drive baffle, make the opening of 1 bottom of inner shell of each baffle 2 closed, promptly through reducing the distance of spout 9 in vertical direction, alright shorten baffle 2 and seal 1 bottom open-ended time of inner shell.
Further, as shown in fig. 1, fig. 3 and fig. 4, in order to prevent the device from moving upward, silt is carried out of the inner shell 1 by the river water from the first water change port 3, the outer shell 10 is also provided with the second water change port 11, the size and shape of the second water change port 11 are consistent with those of the first water change port 3, when the opening at the bottom of the inner shell 1 is in the state of being opened to the maximum extent, the first water change port 3 is exactly aligned with the second water change port 11, and when the outer shell 10 slides downward relative to the inner shell 1 until the baffle 2 and the supporting step 5 completely close the opening at the bottom of the inner shell 1, the outer shell 10 and the inner shell 1 are mutually dislocated, so that the first water change port 3 is exactly sealed by the side wall of the outer shell 10.
Further, for reducing the friction between stopper 4 and baffle 2, make opening or closing of baffle 2 more smoothly, in this embodiment, stopper 4 is the cylinder, and this cylinder rotates through the pivot and connects on the connecting piece, and this cylinder and baffle 2 rolling contact can drive baffle 2 and swing down.
Further, for making things convenient for the more effectual silt of pouring out of staff, roof 7 is worn out to bracing piece 6, this bracing piece 6 through the bolt 12 and the bracing piece 6 looks fixed connection who passes the mounting 13 of welding on roof 7, when needs take out silt, screw out bracing piece 6 with bolt 12, the bracing piece 6 that upwards slides again makes support step 5 and baffle 2 break away from, each baffle 2 can be in proper order the lower hem until wearing out the opening of inner shell 1 bottom, this opening is opened completely this moment, the staff alright pour out silt from this opening.
Further, for making things convenient for the more effective silt of pouring out of staff, the top of inner shell 1 is connected with roof 7 through hasp (not shown in the figure), the hasp is equipped with two at least, in this embodiment, the hasp is equipped with four and establishes respectively on the wall of four of inner shell 1, staff's accessible unblock hasp, make roof 7 and inner shell 1's lateral wall separate, the open-top of inner shell 1 this moment, alright pour silt from the top directly, the structure of above-mentioned hasp itself is prior art, and here is no longer repeated its.
Furthermore, in order to enable the device to collect more silt at one time, a counterweight is detachably and fixedly connected to the top plate 7.
Furthermore, in order to enable the device to be inserted into silt more smoothly, the bottom of the supporting step 5 is a rectangular pyramid which is vertically downward.
To sum up, the utility model discloses a use does: when silt in a river channel needs to be sampled, the device can be placed right above a sampling point, so that the silt can freely fall into river water and sink under the influence of gravity and water only (at the moment, a steel wire rope is in a loose state), in the sinking process of the device, flowing water impacts a baffle 2 to enable the baffle to swing upwards so as to open an opening in the bottom of an inner shell 1, after the bottom of the inner shell 1 is contacted with the silt, due to the fact that the inner shell 1 is heavy and provided with a balancing weight, the inner shell 1 drives an outer shell 10 to be rapidly inserted into the silt through limiting of a connecting piece through a sliding groove 9, the silt upwards extrudes the baffle 2 to enable the baffle 2 to swing upwards until the baffle 2 is contacted with each roller, at the moment, the bottom of the inner shell 1 is opened to the maximum degree, the silt is pressed into a containing cavity from the opening in the bottom of the inner shell 1, water originally in the containing cavity is discharged through a first water changing water port 3 and a second water changing port 11, a limiting block 4 limits the swing of the baffle 2, so that the baffle 2 and the baffle 2 always forms a certain angle with the inner wall, when the baffle 2 is adopted, the baffle 2 is pulled upwards to drive the steel wire rope to drive the inner shell to ascend and slide downwards to enable the baffle 2 to further support the bottom of the inner shell to abut against the bottom of the roller 1, and further support the roller 2, and the bottom of the roller 2, and the roller 1, and the roller 2, and the roller 1, and the silt is further support the bottom of the roller, and the roller 1, and the silt, the silt is collected; after this device pulled out the surface of water, the staff made support step 5 and baffle 2 break away from through unloading bolt 12 on roof 7 again to the sliding support pole 6 that makes progress, can release baffle 2 of inner shell 1 bottom, and each baffle 2 can be in proper order the lower hem until wearing out the opening of inner shell 1 bottom, and this opening is opened completely this moment, and the staff can pour silt from it smoothly.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
