DETAILED DESCRIPTION

[0033] 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.

[0034] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figure 1-3The utility model provides a sewage sedimentation device for water conservancy construction, including a tank body 1 and a plurality of partitions. One end of the tank body 1 is connected to a cleaning pipe 2 for conveying cleaning liquid to assist in cleaning the sludge on the inner bottom surface of the tank body 1, and the other end is connected to an inlet pipe 3 and a sewage pipe 4. The inlet pipe 3 is used to convey sewage formed by water conservancy construction, and the sewage pipe 4 is used to discharge clean water from the tank body 1 when the tank body is cleaned. The inner bottom surface of the tank body 1 is designed to be an inclined surface, and this inclined surface is inclined downward along one end of the tank body 1 toward the other end to facilitate the flow of clean water. The partition is rotatably connected to the inside of the sedimentation tank through a first rotating shaft 5 arranged in the vertical direction. Multiple partitions rotatably divide the tank body 1 into multiple sedimentation spaces, which can effectively treat the sewage in layers and improve the efficiency of sewage treatment.

[0036] Preferably, the device further comprises a first closing plate 6 and a second closing plate 7 respectively fixedly connected to the inner side wall of the tank body 1. The first closing plate 6, the second closing plate 7 and the partition are arranged one by one. A first rotating shaft 5 is fixedly connected to the end surface of the first closing plate 6 away from the cleaning pipe 2, and one end of the partition is hinged to the first rotating shaft 5. The other end of the partition is rotatably abutted against the second closing plate 7 to achieve the purpose of dividing the tank body 1 into a plurality of deposition spaces.

[0037] In a preferred embodiment of the present invention, the partition includes an upper partition 8 and a lower partition 9, and the upper end of the lower partition 9 is rotatably connected to the lower end of the upper partition 8. One end of the upper partition 8 is hinged to the first rotation axis 5, and the ends of the upper partition 8 and the lower partition 9 away from the first rotation axis 5 are rotatably abutted against the second closing plate 7.

[0038] Combined with reference Figure 4 In order to realize the automatic flipping of the lower partition 9, it is ensured that the upper partition 8 is close to the inner wall of the pool body 1, and there is a gap between the lower partition 9 and the inner wall of the pool body 1, so as to facilitate the cleaning of the interior of the pool body 1. A first bevel gear 10 is fixedly connected to the lower end of the first rotating shaft 5 of the utility model. A second rotating shaft 11 is fixedly connected to the upper end of the lower partition 9, and the second rotating shaft 11 is rotatably connected to the upper partition 8. A second bevel gear 12 is coaxially fixedly connected to the second rotating shaft 11, and the second bevel gear 12 is meshed with the first bevel gear 10. When the ends of the upper partition 8 and the lower partition 9 away from the first rotating shaft 5 abut against the second closing plate 7, the lower end of the lower partition 9 abuts against the inner bottom surface of the pool body 1; when the ends of the upper partition 8 and the lower partition 9 away from the first rotating shaft 5 move in a direction away from the second closing plate 7, the lower partition 9 flips upward along the second rotating shaft 11.

[0039] The first bevel gear 10 and the second bevel gear 12 are provided with a protective sleeve (not shown in the figure) on the circumferential side, and the two ends of the protective sleeve are respectively connected to the lower partition plate 9 and the first closing plate 6. The protective sleeve is made of a flexible and telescopic material, such as rubber, to prevent sewage from corroding the first bevel gear 10 and the second bevel gear 12.

[0040] In order to improve the sealing performance of the connection between the upper partition 8 and the lower partition 9, a sealing plate 13 is fixedly connected to the plate surface of the upper partition 8 away from the flip side of the lower partition 9. The connection between the upper partition 8 and the lower partition 9 is arranged opposite to the sealing plate 13.

[0041] Preferably, the first bevel gear 10 and the second bevel gear 12 are both half bevel gears, which can save material and reduce weight.

[0042] In order to further improve the sealing performance of the first closing plate 6 and the second closing plate 7, a first sealing strip 14 is embedded and installed on one side of the first closing plate 6 and the second closing plate 7 facing the upper partition 8, and the first sealing strip 14 selectively cooperates with the upper partition 8 and the lower partition 9. At the same time, a second sealing strip 15 is fixedly connected to the lower end of the lower partition 9, and the second sealing strip 15 is adapted to the inner bottom surface of the pool body 1.

[0043] For easy operation and maintenance, refer to Figure 5 A latch rod 16 is rotatably connected to the plate surface of the upper partition plate 8 away from the first rotating shaft 5. A latch bracket 17 is fixedly connected to the second closing plate 7, and the latch rod 16 is rotatably connected to the latch bracket 17.

[0044] Finally, in order to optimize the water flow path and increase the sedimentation time, the upper baffle 8 is provided with diversion holes 18, and the diversion holes 18 between adjacent upper baffles 8 are arranged in a staggered manner. An overflow groove 19 is provided at the top of the end of the pool body 1 close to the cleaning pipe 2. The outlet end of the water inlet pipe 3 is located above the water inlet end of the sewage pipe 4, which can ensure that the sewage can flow smoothly into the pool body 1 and be effectively sedimented.

[0045] The working principle of this utility model:

[0046] During operation, the cleaning pipe 2 and the sewage pipe 4 are closed, and the upper partition 8 is rotated so that the end thereof away from the first closing plate 6 abuts against the second closing plate 7. During this process, the lower partition 9 is flipped downward until it is in a vertical state. At this time, the second sealing strip 15 has an interference fit with the ground of the pool body 1; then, the latch rod 16 is rotated to make it clamped on the latch bracket 17 to achieve locking between the upper partition 8 and the second closing plate 7. At this time, multiple upper partitions 8 and lower partitions 9 divide the pool body 1 into multiple sedimentation spaces, and the water inlet pipe 3 is opened. The sewage generated by the water conservancy construction is transported to the pool body 1 through the water inlet pipe 3, and is transmitted to different sedimentation spaces through the diversion hole 18, realizing a step-by-step sedimentation process, and then the upper clean water is discharged from the overflow trough 19.

[0047] When cleaning the tank body 1, close the water inlet pipe 3, and rotate the latch rod 16 to release the latch bracket 17, thereby achieving the unlocking effect between the upper partition 8 and the second sealing plate 13; at this time, by rotating the upper partition 8, the end away from the first closing plate 6 is rotated in the direction away from the second closing plate 7, and synchronously, the lower partition 9 is flipped upward and gradually separated from the bottom of the tank body 1; until the upper partition 8 is attached to the inner wall of the tank body 1, at this time there is a certain distance between the lower partition 9 and the bottom of the tank body 1, and cleaning liquid is injected through the cleaning pipe 2 to assist manual cleaning of the sludge, and then the clean water and sludge after cleaning are discharged through the sewage pipe 4.

[0048] Since the pool body 1 of the utility model is provided with a single inclined surface and no bending section is provided, there is no cleaning dead angle, which facilitates the flow of cleaning liquid; and through rotation, the upper partition 8 can be attached to the inner wall of the pool body 1, and there is a certain gap between the lower partition 9 and the bottom of the pool body 1, which is convenient for personnel to move in the pool body 1 and clean the space below the partition.

[0049] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0050] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
