[0048] Manholes are equipment used for personnel entry and exit, maintenance or inspection, and are widely used in various facilities, such as communication pipelines, boilers, storage tanks, etc. Sanitary equipment needs to be equipped with manholes to facilitate internal cleaning due to its special hygiene requirements.

[0049] After extensive research, the inventors discovered that the manholes in current sanitary equipment are mostly welded together, resulting in high manhole heights and requiring a high level of spraying to clean the interior. Furthermore, the flanges are forged, resulting in high material costs, and the welds require grinding and polishing after welding, further increasing production costs.

[0050] Based on this, the present application provides a sanitary manhole to solve the above technical problems, with specific reference to the following embodiments.

[0051] Reference Figure 1-5 As shown, an embodiment of the present application discloses a sanitary manhole 100, which includes a first cylinder 1, a second cylinder 2, a head 3 and a clamping mechanism 4. The first end of the first cylinder 1 is used to connect with the sanitary equipment, and the second end is provided with a first flange surface 11. The first end of the second cylinder 2 is provided with a second flange surface 21 for sealing connection with the first flange surface 11. The head 3 is provided at the second end of the second cylinder 2. The first cylinder 1 and the second cylinder 2 can be locked by the clamping mechanism 4. The first cylinder 1 and the second cylinder 2 are formed by rolling the plate.

[0052] The first flange surface 11 and the second flange surface 21 are annular structures to ensure that when the second cylinder 2 is opened, personnel can enter the interior of the equipment through the first cylinder 1.

[0053] The first cylinder 1 and the second cylinder 2 in the sanitary manhole 100 provided in the present application are formed by rolling a plate, and a first flange surface 11 is provided on one end of the first cylinder 1, and a second flange surface 21 is provided on one end of the second cylinder 2, which has the advantages of simple structure and low cost.

[0054] At the same time, it is no longer restricted by the traditional split cylinder and flange, and the height of the first cylinder 1 and the second cylinder 2 can be designed to be shorter, thereby reducing the internal area of the manhole, and then reducing the amount of spraying required for cleaning the inside of the manhole, and is conducive to reducing the weight of the manhole and facilitating the opening and closing of the manhole.

[0055] In another embodiment, one of the first barrel 1 and the second barrel 2 is formed by rolling a plate, which also has the advantages of simple structure and low cost, and can reduce the height of the manhole and the amount of spray required for cleaning the inside of the manhole.

[0056] For further information, please refer to Figure 4 As shown, the outer diameter of the first cylinder 1 remains unchanged along the axial direction of the first cylinder 1 (the X direction in the figure). After the first cylinder 1 is formed by rolling the sheet, one side surface of the sheet is the outer surface of the first cylinder 1. Therefore, the outer diameter of the first cylinder 1 can remain unchanged along the axial direction of the first cylinder 1. Please continue to refer to Figure 4 As shown, similarly, after the second cylinder 2 is formed by rolling the plate, the outer diameter of the second cylinder 2 remains unchanged along the axial direction of the second cylinder 2.

[0058] Specifically, when the manhole is opened, the pressing mechanism is first removed, and then the second cylinder 2 is rotated relative to the first cylinder 1 through the rotating assembly 5 to open the manhole.

[0059] The existence of the rotating assembly 5 makes it easier to open and close the manhole. At the same time, when the manhole is closed, the first cylinder 1 and the second cylinder 2 can be directly and accurately aligned.

When the second barrel 2 rotates relative to the first barrel 1, the stopper 6 limits the rotation angle of the second barrel 2, preventing the second barrel 2 from excessively rotating and squeezing other components and causing damage. The stopper 6 also serves as a support, providing support when the second barrel 2 rotates to a target angle relative to the first barrel 1, thereby achieving full opening of the manhole. Optionally, the stopper 6 is a block-shaped or plate-shaped structure.

[0064] In one embodiment, the limit member 6 is provided on the first cylinder 1, and the limit member 6 abuts against the second cylinder 2 when the second cylinder 2 rotates to the target angle relative to the first cylinder 1.
