Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment tanks, and mainly mentions a bolt-assembled stainless steel water tank based on a corrugated plate structure. Background Art

[0002] Sewage treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. Sewage treatment plants mainly purify sewage through biochemical systems and finally discharge it after meeting the discharge standards. Sewage treatment plant pools generally use reinforced concrete pool structures. Due to the many and complex processes in the construction of concrete pools, a large number of templates are required, the workload on site is large, and the construction period is long. Prefabricated stainless steel pools are prefabricated in factories and assembled on site, which greatly reduces the on-site construction time and labor requirements, allowing the pools to be put into use quickly. Therefore, prefabricated pools have gradually entered the public eye.

Although fixing rods are installed inside the pool to enhance the stability of the pool, after long-term use, the connection between the side wall of the pool and the fixing rod will become loose, and the side wall of the pool will undergo slight deformation.

[0034] like Figure 1 , Figure 8-Figure 10 As shown, the tension detection mechanism includes a first sprocket 18, which is rotatably connected to the bottom plate of the above-mentioned pool through a mounting seat, and the top of the rear side of the above-mentioned pool is rotatably connected to the second sprocket 19 through a mounting seat, and the second sprocket 19 is composed of a rotating shaft and a sprocket, and the second sprocket 19 is connected to the mounting seat through the rotating shaft, and a chain is wound around the first sprocket 18 and the second sprocket 19, and a slide groove is provided on the rear side of the swing rod 5, and a connecting column is slidably connected in the slide groove of the swing rod 5, and the connecting column on the swing rod 5 is fixedly connected to the above-mentioned chain through the connecting seat, and in the process of the right end of the swing rod 5 swinging upward, the connecting column drives the above-mentioned chain to move synchronously, and the above-mentioned chain rotates around the first sprocket 18 and the second sprocket 19, and at the same time, the connecting column slides along the slide groove of the swing rod 5, and the second pillar 2 on the front side is installed The plate is fixedly connected with a second fixed rod 20, and the second pillar 2 on the rear side is fixedly connected with a fixed plate 21. The second fixed rod 20 passes through the fixed plate 21 and the two are slidably connected. The rear end of the second fixed rod 20 is fixedly connected with a limiting plate. A first elastic member 22 is fixedly connected between the limiting plate of the second fixed rod 20 and the fixed plate 21. The first elastic member 22 is configured as a spring. The first elastic member 22 is wound around the outside of the second fixed rod 20. The first elastic member 22 is located on the rear side of the fixed plate 21. The limiting plate of the second fixed rod 20 is fixedly connected with a second hydraulic rod 23. The second hydraulic rod 23 is an existing ordinary hydraulic telescopic rod, and its internal structure is not shown in the accompanying drawings. The telescopic end of the second hydraulic rod 23 is fixedly connected to the fixed plate 21, and a limiting assembly is arranged on the mounting seat of the second sprocket 19. The limiting assembly is used to control the position of the buoy 6.

[0035] like Figure 8 , Fig.10 and Fig.11 As shown, the limiting assembly includes a limiting wheel 24, which is fixedly connected to the rotating shaft of the second sprocket 19, and the limiting wheel 24 is provided with limiting grooves with circumferential equal spacing. The mounting seat of the second sprocket 19 is fixedly connected with a third hydraulic rod 25, and the third hydraulic rod 25 is located on the left side of the second sprocket 19. The third hydraulic rod 25 is an existing ordinary hydraulic telescopic rod, and its internal structure is not shown in the accompanying drawings. An oil guide pipe is connected between the third hydraulic rod 25 and the second hydraulic rod 23. The oil storage chamber of the second hydraulic rod 23 is larger than the oil storage chamber of the third hydraulic rod 25, which is used to increase the moving stroke of the telescopic end of the third hydraulic rod 25. The second hydraulic rod 23 is filled with hydraulic oil, and the telescopic end of the third hydraulic rod 25 is splined with a spline rod. The spline rod on the telescopic end of the third hydraulic rod 25 is fixedly connected with a limiting block 26, and the limiting block 26 is limitedly matched with the limiting groove of the limiting wheel 24. The limiting block 26 is set in a wedge shape to facilitate the limiting block 26 to be inserted into the limiting groove of the limiting wheel 24. The spline rod on the telescopic end of the hydraulic rod 25 is fixedly connected with a fixed block 27, and the fixed block 27 is provided with a blind hole. The mounting seat of the second sprocket 19 is fixedly connected with a support plate 28, and the support plate 28 is slidably connected to a limit column 29, and the limit column 29 is limitedly matched with the blind hole of the fixed block 27. The left and right sides of the fixed block 27 are provided with inclined surfaces, and the lower end of the limit column 29 is set as a ball head, which is convenient for the fixed block 27 to be limitedly matched with the limit column 29. The support plate 28 is fixedly connected with a positioning plate 30, which is limited. The positioning column 29 passes through the positioning plate 30, and a mounting plate is fixedly connected to the middle part of the limiting column 29. A second elastic member 31 is fixedly connected between the mounting plate of the limiting column 29 and the positioning plate 30. The second elastic member 31 is configured as a spring. The second elastic member 31 is sleeved on the limiting column 29. A third elastic member 32 is fixedly connected between the fixed block 27 and the telescopic end of the third hydraulic rod 25. The third elastic member 32 is configured as a tension spring. The third elastic member 32 is sleeved on the spline rod on the telescopic end of the third hydraulic rod 25.

[0036] The staff assembled the pool on site. In the initial state, the swing arm 5 was tilted, the float 6 was located at the bottom of the pool, the screw 11 and the threaded hole of the first fixed rod 8 were threadedly matched, the first fixed rod 8, the screw 11, the rotating column 10 and the first fixed seat 9 were matched to fix the second pillars 2 on the front and rear sides, and the limit block 26 was limitedly matched with the limit groove of the limit wheel 24. After sewage was injected into the pool, the float 6 was subject to buoyancy in the sewage.

[0037] After the pool has been used for a long time, the sewage pressure acts on the inner wall of the pool. Since the two second pillars 2 are under stress for a long time, and the two second pillars 2 are under stress for a long time, the connection between the first fixing rod 8 and the first fixing seat 9 and the adjacent second pillars 2 becomes loose, and the distance between the upper ends of the two second pillars 2 increases. At this time, the front mounting plate drives the second fixing rod 20 to move forward, and the second fixing rod 20 squeezes the first elastic member 22 through the mounting plate. The first elastic member 22 is compressed, and at the same time, the telescopic end of the second hydraulic rod 23 contracts. After being squeezed, the hydraulic oil in the second hydraulic rod 23 flows into the third hydraulic rod 25 along the oil guide pipe. As the pressure in the third hydraulic rod 25 gradually increases, the third hydraulic rod 25 The telescopic end has a tendency to shrink inward. At this time, the blind hole of the fixed block 27 and the lower end of the limiting column 29 are in a limited matching state. As the hydraulic oil pressure in the third hydraulic rod 25 increases, the telescopic end of the third hydraulic rod 25 begins to shrink, and the third elastic member 32 is gradually stretched. When the deformation of the upper ends of the two second pillars 2 reaches the specified distance, the tension of the third elastic member 32 is greater than the limiting force of the limiting column 29 and the blind hole of the fixed block 27. Under the tension of the third elastic member 32, the fixed block 27 drives the limiting block 26 to move to the right synchronously. At this time, the second elastic member 31 is compressed, and the limiting column 29 gradually moves out of the blind hole of the fixed block 27. When the limiting column 29 completely loses contact with the fixed block 27, the second elastic member 31 is reset.

[0038] In the above process, the limiting grooves of the limiting block 26 and the limiting wheel 24 lose their limiting positions, the third elastic member 32 is reset, and the limiting block 26 releases the limiting position on the limiting wheel 24. Under the action of the buoyancy of the buoy 6, the buoy 6 drives the right end of the swing rod 5 to swing upward, and the swing rod 5 drives the chain transmission between the first sprocket 18 and the second sprocket 19 through the connecting column thereon. At the same time, the connecting column of the swing rod 5 slides synchronously along the slide groove thereon, and the second sprocket 19 drives the limiting wheel 24 to rotate synchronously through its rotating shaft. In the process of the right end of the swing rod 5 swinging upward, the swing rod 5 rotates along the fixed shaft 4, and under the action of the through groove at the left end of the swing rod 5, the left end of the swing rod 5 drives the extension of the first hydraulic rod 7 through the connecting piece. The retracted end moves downward. Under the action of the lever principle, the left end of the swing rod 5 pulls the telescopic end of the first hydraulic rod 7 downward with a pulling force that is 20 times the buoyancy of the buoy 6. During the downward movement of the telescopic end of the first hydraulic rod 7, the hydraulic oil in the first hydraulic rod 7 is squeezed and flows along the oil guide pipe. The hydraulic oil in the first hydraulic rod 7 flows into the hydraulic input port of the hydraulic motor 16. The hydraulic oil drives the output shaft of the hydraulic motor 16 to rotate. Under the action of the reduction structure of the hydraulic motor 16, the output shaft of the hydraulic motor 16 drives the second gear 17 thereon to rotate, and the second gear 17 drives the second rack 15 to move leftward. The second rack 15 drives the first rack 14 to slide slowly to the left along the second fixed seat 13, so as to Figure 1From the perspective of perspective, the first rack 14 drives the first gear 12 to rotate counterclockwise, the first gear 12 drives the rotating column 10 to rotate along the first fixed seat 9, the rotating column 10 drives the lead screw 11 to rotate counterclockwise, the lead screw 11 pulls the first fixed rod 8 toward the rear through the thread, and the tension between the first fixed rod 8 and the lead screw 11 gradually increases. At this time, the tension of the first fixed rod 8 and the first fixed seat 9 acts on the two second pillars 2 respectively, so that the two second pillars 2 are subjected to tension on the opposite sides, and the distance between the upper ends of the two second pillars 2 is gradually restored.

[0039] In the process that the two second pillars 2 are gradually subjected to tension, the second fixed rod 20 slides backward along the fixed plate 21 and gradually resets, and at the same time, the first elastic member 22 loses extrusion and gradually resets, and the telescopic end of the second hydraulic rod 23 extends again, and then the hydraulic oil in the third hydraulic rod 25 gradually flows back to the second hydraulic rod 23 along the oil guide pipe, and the telescopic end of the third hydraulic rod 25 extends, and the telescopic end of the third hydraulic rod 25 pushes the spline rod thereon to the right, and the telescopic end of the third hydraulic rod 25 pushes the fixed block 27 and the limit block 26 to move to the right through the spline rod, and the inclined surface on the right side of the fixed block 27 squeezes the lower end of the limit column 29, and the limit column 29 slides upward along the support plate 28 and the positioning plate 30, and the second elastic member 31 is compressed until the limit block 26 is again limited and matched with the limit groove of the limit wheel 24, and the limit block 26 is used to limit the limit wheel 24, and then the swing angle of the swing rod 5 is limited to avoid the swing angle of the swing rod 5 being too large, resulting in the tension of the two second pillars 2 being unbalanced.

[0040] Subsequently, under the elastic force of the second elastic member 31, the limiting column 29 is reinserted into the blind hole of the fixing block 27, the limiting wheel 24 stops rotating, and then the second sprocket 19 and the first sprocket 18 also stop rotating synchronously, and the chains on the second sprocket 19 and the first sprocket 18 limit the swing rod 5 again through the connecting column, and the buoy 6 stops continuing to drive the right end of the swing rod 5 to swing upward, thereby ensuring that after the two second pillars 2 return to their initial state, they are no longer deformed inward by excessive tension, so that the second pillar 2 will not be excessively deformed due to the pressure of the sewage, reducing stress concentration and increasing the service life of the pool. When the buoy 6 completely floats to the water surface, the staff observes the position of the buoy 6 and promptly inspects the pool. After the inspection is completed, the buoy 6 is reset to the bottom of the pool.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
