However, the filter net in the above technical solution is fixed, and the filter net cannot be quickly disassembled for cleaning, which affects the subsequent ballast tank water level adjustment, which has certain shortcomings. To this end, we provide a detachable water inlet valve core assembly to solve the above problems. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 3As shown, an embodiment of the utility model provides a detachable water inlet valve core assembly, specifically comprising a water inlet valve body 1, a water outlet pipe 2 and a water inlet pipe 3, the outer surface of the input end of the water inlet valve body 1 and the outer surface of one end of the water inlet pipe 3 close to the water inlet valve body 1 are both provided with fastening threads 6, and the input end of the water inlet valve body 1 and the connecting position of the water inlet pipe 3 are threadedly connected with a first fastening nut 4, and through the provided first fastening nut 4, the water inlet valve body 1 can be installed above the water inlet pipe 3 and can be easily disassembled, which is conducive to the later disassembly and maintenance of the water inlet valve body 1. The outer surface of the output end of the water inlet valve body 1 and the outer surface of one end of the water outlet pipe 2 close to the water inlet valve body 1 are both provided with fastening threads 6, and the second fastening nut 5 is threadedly connected to the connection position between the output end of the water inlet valve body 1 and the water outlet pipe 2, and the inner wall of the water inlet pipe 3 is slidably connected with a filter screen 7. The inner wall of the water inlet pipe 3 is provided with a slide groove adapted to the filter screen 7, so that the filter screen 7 can slide on the inner wall of the water inlet pipe 3, which is convenient for the subsequent disassembly or installation of the filter screen 7.

[0029] See also Figure 5 As shown, two disassembly components 8 are provided on the outside of the filter 7, and the two disassembly components 8 both include a fixed bin 801 and a limiting bin 802. The bottom surface of the fixed bin 801 is fixedly connected to the inner wall of the water inlet pipe 3, and the outer surface of the fixed bin 801 is slidably connected to the inner wall of the mounting hole 11. The outer surface of the fixed bin 801 and the inner wall of the mounting hole 11 should be set to be relatively smooth, so that the fixed bin 801 can slide on the inner wall of the mounting hole 11, which is convenient for the subsequent installation of the filter 7. The bottom surface of the limiting bin 802 is fixedly connected to the inner wall of the fixed bin 801, and the inner wall of the limiting bin 802 is slidably connected to a movable plate 803. The inner bottom wall of the limiting bin 802 is fixedly connected to a first spring 804. One end of the first spring 804 away from the inner bottom wall of the limiting bin 802 is fixedly connected to the bottom surface of the movable plate 803. The outer surface of the movable plate 803 is fixedly connected to two sliders 809. The outer surfaces of the two sliders 809 are both slidably connected to the inner wall of the limiting bin 802. The inner wall of the movable plate 803 is provided with a sliding groove adapted to the slider 809, so that the slider 809 can slide in the sliding groove, which is convenient for the subsequent contraction of the limiting block 805 to release the limit.

[0030] See also Figure 5 As shown, the disassembly component 8 also includes two limit blocks 805, and the outer surfaces of the two limit blocks 805 are slidably connected to the inner wall of the fixed bin 801. The side surfaces of the two limit blocks 805 that are close to each other are fixedly connected with a second spring 810, and the ends of the two second springs 810 that are away from the limit blocks 805 are fixedly connected to the outer surface of the limit bin 802. By setting the second spring 810, when the filter screen 7 is installed, the second spring 810 will be compressed when the filter screen 7 contacts the limit block 805. When the filter screen 7 moves to the limit block 805 and leaks out, the second spring 810 will immediately pop out to drive the limit block 805 to extend to limit the filter screen 7.

[0031] See also Figure 4 and Figure 5 As shown, the side of the two limit blocks 805 close to each other is fixedly connected with the first positioning groove 806, the inner walls of the two first positioning grooves 806 are rotatably connected with the connecting rod 807, and the ends of the two connecting rods 807 away from the first positioning groove 806 are rotatably connected with the second positioning groove 808. Through the rotatable connection between the connecting rod 807, the second positioning groove 808 and the first positioning groove 806, the second positioning groove 808 can drive the limit block 805 to shrink when moving downward, so as to facilitate the release of the limit of the filter 7. The side of the two second positioning grooves 808 close to the limit bin 802 is fixedly connected with the outer surfaces of the two sliders 809, the outer surface of the filter 7 is provided with two mounting holes 11, the upper surface of the filter 7 is fixedly connected with two third positioning grooves 9, and the inner walls of the two third positioning grooves 9 are rotatably connected with the handle 10. Through the provided handle 10, the filter 7 can be conveniently taken out from the inside of the water inlet pipe 3 for cleaning after the limit of the filter 7 is released.

[0032] The specific working principle of the utility model is as follows: when the filter screen 7 is clogged by debris carried by seawater and needs to be cleaned, firstly, the first fastening nut 4 and the second fastening nut 5 are respectively screwed to remove the water inlet valve body 1 from the top of the water inlet pipe 3, and the moving plate 803 is pressed to make the moving plate 803 drive the two sliders 809 to move downward, and when the sliders 809 move downward, the second positioning groove 808 is driven to move in the same direction, and the connecting rod 807 is connected with the second positioning groove 808 and the first positioning groove 806 by rotation. When 8 moves downward, it drives the first positioning groove 806 to move in the direction of the limiting bin 802. When the first positioning groove 806 moves in the direction of the limiting bin 802, it drives the limiting block 805 to move in the same direction, so that the limiting block 805 shrinks into the interior of the fixed bin 801, thereby releasing the limiting block 805 on the filter screen 7. After the filter screen 7 is released from the limit, the filter screen 7 can be removed by pulling the handle 10, thereby achieving the effect of disassembling the filter screen 7, facilitating the cleaning of the filter screen 7, and avoiding the subsequent ballast tank water level adjustment affected by the blockage of the filter screen 7.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
