The invention provides a coring bit suitable for soft-hard drilling objects. The coring bit comprises a bit base body and a conical head arranged below the bit base body, wherein the bit base body is in a hollow cylinder shape; a drill stem connecting part is arranged at the upper end of the bit; the inner diameter of an opening of the conical head is smaller than the inner diameter of the hollow cylinder of the bit base body; an external spiral is arranged on the outer surface of the bit base body; grooves are formed in the inclined surface and the bottom surface of the conical head; cutting tools with corresponding shapes are arranged in the grooves and are riveted in the grooves through rivets; a limiting piece for limiting initial positions of the cutting tools is formed between holes in the rivets and the cutting tools; a high-temperature-resistant elastic cushion block is arranged between the cutting tools arranged between the limiting piece and the bottom of the groove and the groove. The coring bit suitable for soft-hard drilling objects is high in adaptability, and hard and soft rocks can be simultaneously crushed without replacing the bit; smooth powder discharge is realized, the cutting heat and friction heat are dissipated out of the hole bottom through drilling cuttings, and the heat dissipation is reduced; in order to improve the cutting efficiency, the cutting blade can have multiple cutting angles by adjusting the size of a rubber cushion block.

The invention relates to a high-fidelity fixed-depth water sample collection device, which includes a frame body, which is used to set up at the wellhead of a monitoring well; a lifting device, which is installed on the frame body; a sampling cylinder, which includes a cylinder body and a sampling bottle And the cover assembly, the sampling bottle is installed in the cylinder, which is filled with anti-oxidant gas, the side wall of the cylinder has a water inlet connected to the inside, the cover assembly is arranged in the cylinder, and the lifting device is connected with the cylinder for driving The cylinder body moves up and down; the uncapping mechanism is installed on the frame body and is connected with the cover assembly, which is used to drive the cover assembly to move to open or seal the water inlet and the mouth of the sampling bottle; the temperature detection device, the temperature The detection device is installed in the cylinder. Advantages: The structural design is reasonable, the sampling water does not come into contact with the air during the whole sampling process, which ensures the high fidelity of the water sample, makes the detection result true and reliable, and the temperature is measured in situ, which greatly reduces the measurement error.
