Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution for a corner floor drain of a marine sanitary unit: It includes a floor drain main body 1. An installation enclosure 2 embedded in the corner of the marine sanitary unit is fixedly installed on the outer periphery of the upper end of the floor drain main body 1. At the four corners of the inner bottom end of the floor drain main body 1, support seats 3 are fixedly installed, and the number of support seats 3 is four, symmetrically distributed at the inner bottom end of the floor drain main body 1. A drain port 4 is fixedly installed at the lower end of the floor drain main body 1. Inside the upper end of the support seat 3, a swing cover 5 is rotatably connected through a pin shaft. An arc-shaped limit groove 6 is opened at the lower side end of the swing cover 5. On both sides of the inner wall of the arc-shaped limit groove 6, a positioning pin column 7 is fitted and movably connected. The outer curved surface of the side end of the positioning pin column 7 penetrates and is fitted and movably connected to the outer wall of the swing cover 5. A positioning pin hole 8 is opened at the inner side of the upper end of the support seat 3, and the outer side end of the positioning pin column 7 is fitted and movably connected to the inner wall of the positioning pin hole 8, so that the swing cover 5 is limited and fixed by the cooperation of the positioning pin hole 8 and the positioning pin column 7. A return spring 9 is fixedly installed inside the positioning pin column 7. A fixing seat 10 is fixedly installed at the side end of the return spring 9 away from the positioning pin column 7, and the fixing seat 10 is fixedly installed on the inner wall of the arc-shaped limit groove 6, so that the positioning pin column 7 is elastically supported by the cooperation of the fixing seat 10 and the return spring 9. A straight opening groove 11 is opened at the outer side of the upper end of the swing cover 5. A T-shaped push button 12 is fixedly installed at the upper end of the positioning pin column 7, and the lower sides of the two ends of the T-shaped push button 12 are fitted and movably connected to the inner wall of the straight opening groove 11, so that the lower end of the T-shaped push button 12 is linearly moved and limited by the straight opening groove 11;
[0024] In the middle of the lower end surface of the swing cover 5, a limit tube 13 is fixedly installed. Inside the lower end inner wall of the limit tube 13, a limit column 14 is fitted and movably connected. At the upper end of the limit column 14, a support spring 15 is fixedly installed, and the support spring 15 is in a compressed state. The upper end of the support spring 15 is fixedly installed at the inner top end of the limit tube 13, so that the limit column 14 is elastically supported by the support spring 15. At the lower end of the limit column 14, a filter disc 16 for blocking and filtering the drainage inside the floor drain main body 1 is fixedly installed, and the outer end of the filter disc 16 is fitted and movably connected to the upper end of the inner wall of the middle part of the floor drain main body 1. An internal thread installation ring 17 is fixedly installed on the inner wall of the lower end of the floor drain main body 1. A filter funnel 18 for secondary filtering of the drainage inside the floor drain main body 1 is threadedly connected to the inner wall of the internal thread installation ring 17.
[0025] Working principle: When in use, the utility model embeds the installation enclosure 2 into the corner of the marine sanitation unit. When the installation enclosure 2 is embedded into the corner of the marine sanitation unit, the drain outlet 4 is communicated with the drain pipe on the ground of the marine sanitation unit. When the drain outlet 4 is communicated with the drain pipe on the ground of the marine sanitation unit, the wastewater generated in the marine sanitation unit will be discharged downward through the inner wall at the upper end of the floor drain main body 1. When the wastewater generated in the marine sanitation unit is discharged downward through the inner wall at the upper end of the floor drain main body 1, the filter disc 16 and the filter funnel 18 will conduct secondary filtration on the discharged wastewater, thus avoiding the situation that the drain pipe is blocked by internal impurities when the wastewater generated in the marine sanitation unit is discharged outward;
[0026] Since the swing cover 5 is limited and fixed by the cooperation of the positioning pin hole 8 and the positioning pin column 7, when the swing cover 5 is limited and fixed, the filter disc 16 will be synchronously driven to be limited and fixed, and the support spring 15 is in a compressed state. When the support spring 15 is in a compressed state, the elastic potential energy generated by the compression deformation of the support spring 15 will always push the filter disc 16 downward through the limit post 14. When the filter disc 16 receives a downward thrust, the filter disc 16 will filter the drainage while always remaining in contact with the upper end of the inner wall in the middle of the floor drain main body 1, thus avoiding the situation that the filter disc 16 loosens due to the high-frequency shaking of the ship;
[0027] At the same time, when it is necessary to clean and maintain the filter disc 16 and the filter funnel 18, by pushing the T-shaped push button 12 inward. When the T-shaped push button 12 is pushed inward, the positioning pin column 7 will be driven to move linearly inward along the inner wall of the arc-shaped limit groove 6. When the positioning pin column 7 moves linearly inward, the compression reset spring 9 will be pushed, and at the same time, the outer end of the positioning pin column 7 leaves the inner wall of the positioning pin hole 8. When the outer end of the positioning pin column 7 leaves the inner wall of the positioning pin hole 8, the limit fixation of the swing cover 5 can be released. When the limit fixation of the swing cover 5 is released, the elastic potential energy generated by the compression deformation of the support spring 15 will push the swing cover 5 to swing upward in the reverse direction. When the swing cover 5 swings upward and opens, the filter disc 16 will be synchronously driven to swing upward and open. When the filter disc 16 swings upward and opens, it is convenient to clean and maintain the filter disc 16 and the filter funnel 18.
