Technical Field
The utility model relates to the technical field of sampling devices, in particular to a novel portable river sediment sampler.
Background
The river channel has important ecological functions, but the river channel also faces environmental pollution and ecological threat, the problem of eutrophication of the river channel water quality is more common, and the ecological environment protection of the river channel is more and more important. The sediment in the river channel is mutually connected with the water quality of the river channel, various substances are mutually converted between the sediment and the water quality of the river channel, the current situation of sediment investigation and sediment cleaning of the river channel is developed, investigation and evaluation are carried out on the sediment, and an important foundation is laid for further protecting the ecological environment of the river channel.
The traditional sediment sampler can only generally adopt sediment samples on the surface layer, and some columnar samplers can collect deep sediment, but the sediment samples are easy to fall off in the process of collecting and lifting soft sediment samples, and the collected samples cannot be mixed to directly watch apparent states such as colors of sediment with different depths.
Disclosure of Invention
The utility model aims to provide a novel portable river sediment sampler, which can be used for collecting deep sediment of different substrates of a river, solving the problem that soft sediment samples are easy to fall off in the process of collecting and lifting, and simultaneously visually observing apparent states such as colors of the sediment with different depths.
The novel river bottom mud sampler comprises a dowel bar, a rotating handle, pedals, a mud storage sleeve and a mud leakage prevention drill bit; the upper part of the dowel bar is connected with the rotary handle and is detachably connected; the middle part of the dowel bar is connected with a plurality of pedals in a hinged unidirectional foldable way; the lower part of the dowel bar is connected with a mud storage sleeve, and the mud storage sleeve is made of transparent glass fiber reinforced plastic; the lower part of the mud storage sleeve is connected with a mud leakage prevention drill bit, and a one-way blocking diaphragm is arranged in the mud leakage prevention drill bit.
Preferably, the dowel bar is detachably connected with the mud storage sleeve by adopting threads.
Preferably, the mud storage sleeve is made of transparent toughened glass, and a water outlet is arranged at the upper part of the mud storage sleeve.
Preferably, the lower part of the mud storage sleeve is detachably connected with the mud leakage prevention drill bit by adopting threads.
Preferably, the top of the mud leakage prevention drill bit is hollowed out and is internally provided with a one-way blocking diaphragm.
Compared with the prior art, the utility model has the following beneficial effects:
through the arrangement of the rotary handle, the pedals and the mud leakage prevention drill bit, the device can be applied to collecting sediment samples of different river geology.
Through the mud storage sleeve made of transparent glass fiber reinforced plastic, the apparent states of the color and the like of the undisturbed bottom mud with different depths can be directly observed.
Through setting up one-way separation diaphragm, prevent effectively that the sample from promoting the in-process and coming off.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic diagram of a mud leakage preventing drill bit according to the present utility model;
in the figure: 1 dowel bar, 2 rotary handle, 3 pedal, 4 mud storage sleeve and 5 mud leakage preventing drill bit.
Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-2, the utility model provides a novel portable river sediment sampler, which comprises a dowel bar 1, a rotary handle 2, pedals 3, a mud storage sleeve 4 and a mud leakage prevention drill bit 5; the rotary handle 2 and the dowel bar 1 are detachably connected; the pedal 3 and the dowel bar 1 are connected in a hinged unidirectional foldable manner; the mud storage sleeve 4 is made of transparent glass fiber reinforced plastic; the top of the mud leakage preventing drill bit 5 is hollowed out and internally provided with a one-way blocking diaphragm 501.
Wherein, all adopt detachable mode to connect between dowel bar 1, twist grip 2, store mud sleeve pipe 4, the leak protection mud drill bit 5, it is convenient to dismantle, and it is convenient to carry, and pedal 3 adopts articulated unidirectional collapsible mode to be connected with dowel bar 1, and twist grip 2 and pedal 3 provide two kinds of propulsion modes of rotatory propulsion and direct propulsion for handheld sampler, overcome the resistance of sampler in the propulsion process.
The upper part of the mud storage sleeve 4 is provided with a drain hole, which is favorable for draining water in the mud storage sleeve, thereby being convenient for pressing river sediment into the mud storage pipe.
The mud storage sleeve 4 is made of transparent glass fiber reinforced plastic materials, so that apparent states such as colors of undisturbed bottom mud with different depths can be directly observed.
The mud leakage prevention drill bit 5 is made of steel, the top of the mud leakage prevention drill bit is provided with a hollow, the hard drill bit can be used for coping with various river bottom materials, the mud leakage prevention drill bit 5 is inserted into river bottom mud, and the bottom mud enters the mud storage sleeve 4 through the hollow drill bit.
The inside one-way separation diaphragm 501 that is provided with of leak protection mud drill bit 5, the one-way separation diaphragm 501 in leak protection drill bit 5 can effectually block the whereabouts of foundation sludge when the foundation sludge promotes the in-process.
