Description

Technical Field

[0001] The utility model relates to a liquid inlet device, in particular to a submerged liquid inlet device. Background Art

[0002] At present, when extracting liquid from natural water bodies such as lakes, rivers or containers, if there is sediment such as sludge at the bottom and debris such as fallen leaves on the liquid surface, the extracted liquid cannot be guaranteed to be clean and the debris will clog the pipe. In addition, the existing liquid extraction device cannot adjust the extraction depth and cannot follow the changes in the liquid level during use, resulting in empty extraction. Utility Model Content

[0003] Purpose of the invention: The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a convenient and quick underwater liquid inlet device that is stable to use, has an adjustable length of metal telescopic tube, can extract liquid at a specific depth, and adjusts the length of the metal telescopic tube by driving a screw rod with a hand wheel.

[0004] Technical solution: In order to solve the above technical problems, the utility model discloses a submersible liquid inlet device, which includes a metal telescopic tube, a plurality of connecting rods are arranged on the outer side of the upper end of the metal telescopic tube, the connecting rods are connected to the float, a bottom valve is arranged on the bottom end of the metal telescopic tube, a connecting plate is arranged on the top end of the metal telescopic tube, a fixed bearing seat is arranged on the connecting plate, a bearing is arranged in the fixed bearing seat, a threaded sleeve is connected to the handwheel and is fixed in the fixed bearing seat through a bearing, a screw passes through the threaded sleeve and the lower part is connected to the metal telescopic tube through a fixed rod, the screw and the threaded sleeve are threadedly connected, a sealing sleeve is arranged on the outside of the screw in the metal telescopic tube, and a liquid outlet is arranged on the upper part of the metal telescopic tube.

[0005] Furthermore, three connecting rods are evenly arranged on the outer side of the upper end of the metal telescopic tube, and each connecting rod is connected to a floating ball.

[0006] Furthermore, the bottom end of the sealing sleeve is higher than the fixing rod.

[0007] Furthermore, the bottom valve is arranged on the metal telescopic tube below the fixing rod.

[0008] Furthermore, the liquid outlet is lower than the float.

[0009] Furthermore, the cross section of the metal telescopic tube is circular.

[0010] Furthermore, the upper end of the sealing sleeve is connected to the bottom end of the fixed bearing seat or the upper end of the sealing sleeve is connected to the bottom end of the connecting plate.

[0011] Furthermore, the connecting plate is a sealing cover plate or a connecting rod type fixing plate.

[0012] Beneficial effect: Compared with the prior art, the utility model has the following significant advantages: after the liquid extraction tube is connected to the liquid outlet, the device is put into the liquid. Due to the buoyancy of the three floats, the device will float steadily on the liquid surface. The hand wheel is turned to drive the threaded sleeve to rotate. Under the action of the thread, the screw can move up and down. Since the lower part of the screw is connected to the metal telescopic tube, the metal telescopic tube will be extended or shortened accordingly to adjust the depth of the bottom valve under the liquid surface. If the liquid level changes during the extraction process, since the device floats on the liquid surface, it can also change accordingly to prevent the bottom valve from leaking out of the liquid surface and being emptied. The floats are arranged in a herringbone shape, which is relatively stable. The length of the metal telescopic tube is adjustable and liquid of a specific depth can be extracted. The length of the metal telescopic tube is adjusted by driving the screw with the hand wheel, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
