Embodiment Construction

[0018] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as Figure 1-2 As shown, the embodiment of the present invention provides a lake sediment sampling device, including a working platform, a control device and a sampler 1, the working platform is composed of several vacuum oil barrels 15, steel frames 3 and wooden boards 5, adjacent The two vacuum oil drums 15 are fixedly connected by a steel frame 3, and the wooden board 5 is fixed on the top of the steel frame 3, and the four corners of the wooden board 5 are fixed with iron rings 4, which are used to connect ship anchors or steel pipes so that they can pass through the iron rings. The ring is inserted into the bottom of the water,...

Abstract

The invention discloses a lake bottom sediment sampling device which comprises an operation platform, a control device and a sampler, wherein the operation platform comprises a plurality of vacuum oil drums, a steel framework and a wood plate; every two adjacent vacuum oil drums are fixedly connected with each other through the steel framework; the wood plate is fixed on the steel framework; iron rings are fixed at four corners of the wood plate; the control device comprises a drill rig, a dill rod, a bracket, an auxiliary bracket, a pulley and a steel rope; the drill rig, the bracket and the auxiliary bracket are mounted on the midpoint on the upper surface of the wood plate; a sampling hole is formed in the midpoint of the wood plate; the upper end of the drill rod is connected with the steel rope; the steel rope is connected with a winch on the drill rig through the pulley; the lower end of the drill rod penetrates a fixing drill hole right above the sampling hole. The lake bottom sediment sampling device has the advantages that the limitation of a channel is avoided; the cost is low; the efficiency is high; the integrity of a sample is high; disassembly and assembly are fast; on-land towing to any water body for sampling is realized; the sampler is high in strength, and excellent in corrosion resistance and compression resistance.

Description

technical field [0001] The invention relates to the field of water environment pollution prevention and control engineering, in particular to a lake sediment sampling device. Background technique [0002] At present, the collection of deep-water bottom mud is mainly divided into three types: excavation type mud extraction device, cone type (drilling type) mud extraction device and tubular mud core sampling device. Although the dredging dredging device has a large amount of dredging at one time, it can only collect samples of 10-20 cm from the surface of the sediment at the deepest point; the cone (drilling) dredging device has the characteristics of simple structure and convenient operation, and its disadvantage is The amount of sampling is small; the tubular mud core sampling device can obtain complete vertically distributed sediment samples. The tube-type mud core sampling device is suitable for the collection of sediment columnar section samples, and has shown strong adv...
