Description

Technical Field

[0001] This utility model relates to the field of marine technology, and in particular to an adjustable nozzle for washing anchor chains. Background Technology

[0002] Ship anchor chain cylinders typically consist of three parts: deck chain holes, side chain holes, and cylinder body; the cylinder body usually contains a flushing device for washing the anchor chain.

[0003] However, existing anchor chain flushing devices typically use fixed nozzles, which require repeated disassembly and adjustment, which is time-consuming, labor-intensive, and cumbersome. At the same time, their fixed angle makes it difficult to cover the sludge accumulation in different positions of the anchor chain cylinder, affecting the cleaning effect and resulting in poor adaptability. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of existing ship anchor chain washing devices, which mostly use fixed nozzles, requiring repeated disassembly and adjustment, which is time-consuming and labor-intensive. Furthermore, the fixed angle makes it difficult to cover sludge accumulation at different locations on the anchor chain, affecting the cleaning effect. This application provides an adjustable nozzle for anchor chain washing. Rotating the handle drives the axial movement of a reducer, changing the spray nozzle angle. The nozzle can be selected according to different pipe diameters to adapt to different pipe diameter requirements. This invention achieves multi-angle adjustment and has a compact structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable nozzle for rinsing anchor chains, comprising a straight pipe, wherein a first flange is fixedly connected to the outer surface of the straight pipe; a nozzle pipe is provided at one end of the straight pipe, and a nozzle of different diameter is provided at the end of the nozzle pipe away from the straight pipe; the diameter of the straight pipe is the same as the diameter of the rinsing pipe of the rinsing device, and the straight pipe is connected to the rinsing pipeline.

[0006] Furthermore, the reducing nozzle is formed by reducing the diameter of one end of the nozzle tube; a portion of the nozzle tube section is selected, and the cross-section of the reduced-diameter section is a right-angled trapezoid.

[0007] Furthermore, a hollow disc is provided on the outer surface of the nozzle tube near the straight tube end, and a handle is provided on the hollow disc.

[0008] Furthermore, a second flange is provided on the side of the hollow disc away from the first flange, the second flange is sleeved on the outer surface of the protective tube, and the protective tube is sleeved on the outer surface of the nozzle tube.

[0009] Furthermore, the first flange and the second flange are connected by bolts and nuts; bolt holes are provided between the first flange and the second flange respectively, and the bolts are fixed by nuts after passing through the bolt holes.

[0010] Furthermore, an annular protrusion is provided on the inner side of the protective tube, and the inner diameter of the annular protrusion is the same as the outer diameter of the nozzle tube, so that the nozzle tube is located in the middle area inside the protective tube.

[0011] Furthermore, gaskets are provided between the first flange and the hollow disc, and between the hollow disc and the second flange, thereby improving the sealing performance.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. The present invention provides an adjustable nozzle for flushing anchor chains. When it is necessary to adjust the nozzle tube angle, the bolts between the second flange and the first flange are removed, and the handle is turned so that the hollow disc and the nozzle tube rotate synchronously in the circumferential direction, thereby changing the position of the unequal-diameter nozzle in the vertical plane. As a result, when the water flows through the unequal-diameter nozzle, it will be sprayed at an angle under the action of its internal inclined surface. When the position of the unequal-diameter nozzle changes, the spray angle of the water flow will also change accordingly, thereby covering the entire circumference of the anchor chain cylinder.

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1:

[0023] Please see Figures 1 to 4 This utility model provides an adjustable nozzle for rinsing anchor chains, comprising a straight pipe 2, with a first flange 1 fixedly connected to the outer surface of the straight pipe 2; a nozzle pipe 7 is provided at one end of the straight pipe 2, and a reducing nozzle 8 is provided at the end of the nozzle pipe 7 away from the straight pipe 2; the diameter of the straight pipe 2 is the same as the diameter of the rinsing pipe of the rinsing device, and the straight pipe 2 is connected to the rinsing pipeline. The reducing nozzle 8 is formed by reducing the diameter of one end of the nozzle pipe 7; a portion of the nozzle pipe 7 is selected, and the cross-section of the reduced-diameter pipe section is a right-angled trapezoid. A hollow disc 3 is provided on the outer surface of the nozzle pipe 7 near the straight pipe 2, and a handle 4 is provided on the hollow disc 3. A second flange 5 is provided on the side of the hollow disc 3 away from the first flange 1, and the second flange 5 is sleeved on the outer surface of a protective pipe 6, which in turn is sleeved on the outer surface of the nozzle pipe 7. The first flange 1 and the second flange 5 are connected by bolts 10 and nuts 11; bolt holes 10 are correspondingly opened between the first flange 1 and the second flange 5, and the bolts 10 pass through the bolt holes 10 and are fixed by nuts 11. The inner side of the protective tube 6 is provided with an annular protrusion 12, the inner diameter of which is the same as the outer diameter of the nozzle tube 7, so that the nozzle tube 7 is located in the middle area inside the protective tube 6; the second flange 5 and the first flange 1 are both fixed to the flushing device.

[0024] When the nozzle needs to be replaced, the second flange 5 is removed and the nozzle tube 7 installed inside the protective pipe 6 is replaced. When the angle of the nozzle tube 7 needs to be adjusted, the bolts 10 between the second flange 5 and the first flange 1 are removed, and the handle 4 is turned so that the hollow disc 3 and the nozzle tube 7 rotate synchronously in the circumferential direction, thereby changing the position of the reducing nozzle 8 in the vertical plane. In this way, when the water flows through the reducing nozzle 8, it will be sprayed at an angle under the action of its internal inclined surface. When the position of the reducing nozzle 8 changes, the spray angle of the water flow will also change accordingly, thus covering the entire circumference of the anchor chain cylinder. This application improves efficiency: the adjustment time is shortened from the traditional 20 minutes to 5 minutes, saving 75% of the working time; the flushing effect is optimized: the spray angle is continuously adjustable, covering the entire circumference of the anchor chain cylinder, and the sludge removal rate is increased by 40%. An annular protrusion 12 is provided on the inner side of the protective tube 6. The inner diameter of the annular protrusion 12 is the same as the outer diameter of the nozzle tube 7, so that the nozzle tube 7 is located in the middle area inside the protective tube 6. The annular protrusion 12 is located between the protective tube 6 and the nozzle tube 7, ensuring that the nozzle tube 7 can rotate relative to the protective tube 6 while the radial position between them is relatively fixed.

[0025] Example 2:

[0026] Unlike the above embodiments, this embodiment, based on the above embodiments, provides gaskets 9 between the first flange 1 and the hollow disc 3, and between the hollow disc 3 and the second flange 5, thereby improving the sealing performance and preventing water leakage.

[0027] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
