Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an aquaculture lake bottom sludge bacterial flora sampling device. Background Art

[0002] Aquaculture can be divided into freshwater aquaculture and marine aquaculture. Freshwater aquaculture requires enclosing a certain area inside lakes, ponds, and reservoirs in designated areas for the survival of fish, shrimps, and crabs, while marine aquaculture uses gauze to enclose a restricted area at the seaside for the survival of organisms, and then realizes the integration of aquatic product processing, cold chain logistics and transportation, and delivers aquatic products to various cities.

[0003] In order to detect whether the water quality meets the breeding requirements, it is necessary to take samples in advance, and send the collected aquatic plants, liquids, and silt for inspection, and then determine whether the breeding standards for a certain type of aquatic products can be met here. The traditional sampling device uses a lifting mechanism to drill the material and then lift it up. The sampler needs to stand on the side of the boat or the shore to operate, which is dangerous and difficult to obtain samples anytime and anywhere.

[0004] Now, a new type of aquaculture lake bottom sludge flora sampling device is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a device for sampling bacterial flora in lake bottom sludge of aquaculture, so as to solve the problem of limited sampling time efficiency in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sampling device for sludge flora at the bottom of an aquaculture lake, comprising a basic frame and a support plate, a support plate is horizontally fixed between the four corners of the top of the basic frame, an electric winding drum is installed at the center above the basic frame, a slot is provided on the right side of the support plate, a perforation is provided on the left side of the support plate, a first guide wheel is installed on the left side of the center of the top of the support plate, a second guide wheel is installed on the left side of the top of the support plate, a steel cable is movably wrapped around the outside of the electric winding drum, a flat plate is welded to the bottom of the steel cable, a bottom plate is provided below the flat plate, side rods are welded to both sides of the center of the top of the bottom plate, baffle rods are welded to both ends of the center of the top of the bottom plate, and the side rods and the baffle rods are both plugged and fixed below the flat plate.

[0007] Preferably, the left side of the steel cable passes through the first guide wheel and the second guide wheel, and the left side of the steel cable is guided by the second guide wheel to change direction.

[0009] Preferably, a transverse groove is provided between the two sides inside the flat plate, and sprockets are movably connected to the two sides inside the transverse groove, chain belts are transversely meshed between the outsides of the sprockets, screw rods are movably connected to the two sides between the flat plate and the bottom plate, and a slider is sleeved on the outside of the screw rod, a DC motor is installed on the top of the slider, and a rotary cylinder is movably connected to the bottom of the slider, circular grooves are provided on both sides inside the bottom plate, an outer slideway is longitudinally provided on the outer side of the side rod, a threaded hole is longitudinally provided on one side inside the slider, and a waterproof motor is installed on the right side of the top of the flat plate.

[0010] Preferably, the bottom of the sprocket is fixedly connected to the screw rod, and the screw rod is embedded in the threaded hole.

[0011] Preferably, an inner slide is longitudinally arranged on the inner wall of the baffle rod, and a positioning block is movably inserted in the inner slide, the positioning block and the inner slide are meshed and connected with bolts, a pressure plate is welded at the bottom between one end of the positioning block, and metal weights are overlapped and placed between the baffle rod and the side rod.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the aquaculture lake bottom sludge bacterial sampling device not only realizes sampling anytime and anywhere, realizes spiral drilling to take materials, but also realizes the adjustment of the weight of the sampling tool;

[0013] (1) By fixing a support plate horizontally between the four corners of the top of the base frame, the base frame is fixed to the shipboard or the river bank with a ground anchor. The top support plate can also be selected according to the extension distance. The flat plate and other objects are suspended by a steel cable, and then the electric reel is turned on. It moves to the left under the guidance of the first guide wheel through the slot, and then passes through the second guide wheel to adjust the surface downward. Under the restriction of the perforation, the flat plate and the collection tool below are vertically lifted and lowered, and sampling can be performed at regular intervals without manual waiting and operation;

[0014] (2) By setting a transverse groove between the two sides of the flat plate, when the bottom plate gradually slides down under the guidance of multiple metal weights, the waterproof motor at the upper right corner can be started to rotate the sprocket on the right side of the transverse groove, and the sprockets on both sides and the screw rod below can be rotated synchronously with the chain belt. The slider sleeved on the outside of the object moves vertically along the outer slideway by means of the threaded hole. At the same time, the DC motor is turned on to rotate the hollow rotary cylinder under the slider, and the slider forms a rotary downward pressure operation to drill the bottom silt, instead of vertical extrusion as in the past, which is more labor-saving;

[0015] (3) By overlapping and placing metal weights between the baffle rod and the side rod, removing the flat plate inserted between the baffle rod and the side rod, and vertically placing each metal weight along the space formed by the baffle rod and the side rod, the height of the positioning block is adjusted along the longitudinal inner slide of the baffle rods at both ends so that the pressure plate fixed between the two ends fits on the top of the metal weight, preventing the metal weight from escaping from the restriction structure due to the buoyancy in the water, thereby ensuring that the sampling tool can be smoothly launched into the water.
