DETAILED DESCRIPTION

[0017] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] like Figures 1 to 3As shown, according to an embodiment of the present invention, a fermentation tank sight glass is provided, which is installed on the right side of the fermentation tank of a biogas system, and includes a lens barrel 1, an internal sliding seal connected to a lens 2, a right end of the lens barrel 1 is fixedly connected to a lock cover 7 for preventing the lens 2 from sliding out of the lens barrel 1, and an internal left end of the lens barrel 1 is fixedly connected to a limit ring 13 for preventing the lens 2 from sliding out of the lens barrel 1; the middle of the lens 2 is rotationally sealably connected to a rotating shaft 3, the rotating shaft 3 passes through the middle of the lens 2, one end of the rotating shaft 3 located inside the lens barrel 1 is fixedly connected to a long strip of wiper 4, and one end of the rotating shaft 3 located outside the lens barrel 1 is fixedly connected to a handle 9, and the wiper 4 is located on the left side of the lens 2 and abuts against the lens 2.

[0019] A water nozzle 15 for spraying water to the left side of the lens 2 is embedded in the lens barrel 1 . The water inlet of the water nozzle 15 is connected to the water inlet pipe, and the water outlet of the water nozzle 15 is flush with the inner wall of the lens barrel 1 .

[0020] A locking hook 5 is fixedly connected to the right side of the lens 2, and a blocking rod 6 that can cooperate with the locking hook 5 is fixedly connected to the right end of the lens barrel 1. When the lens 2 rotates to a certain position, the locking hook 5 will be blocked by the blocking rod 6, so that the lens 2 cannot continue to rotate and move left and right; by providing the locking hook 5 and the blocking rod 6, when the rotating shaft 3 drives the wiper 4 to clean the lens, the lens 2 can be kept stationary, and the wiper 4 can rotate relative to the lens 2 to clean the lens.

[0021] The lock cover 7 is annular, and a lock cover connecting ring 8 for connecting the lock cover 7 is fixedly connected to the right end of the lens barrel 1, and the lock cover connecting ring 8 is fixedly connected to the lock cover 7 by bolts.

[0022] The windshield wiper 4 includes a brush body 401 and a brush body frame 402 . The brush body frame 402 is fixedly connected to the rotating shaft 3 , and the brush body 401 is bolted to the brush body frame 402 .

[0023] A first rubber ring 10 is sleeved on the connection position of the rotating shaft 3 with the lens 2, and the rotating shaft 3 is rotationally sealed and connected to the lens 2 through the first rubber ring 10; a second rubber ring 11 is sleeved on the outer end of the lens 2, and the lens 2 is slidingly sealed and connected to the lens barrel 1 through the second rubber ring 11.

[0024] The position of the rotating shaft 3 located on the right side of the lens 2 is fixedly connected to a limiting sleeve 12 , and the limiting sleeve 12 abuts against the lens 2 ; by providing the limiting sleeve 12 , the lens 2 is limited.

[0025] The outer left end of the lens barrel 1 is fixedly connected with a connecting plate 14 for connecting with a fermentation tank.

[0026] The working principle of the above embodiment is: When the fermentation tank is in working state, the lens 2 is located at the right end inside the lens barrel 1. The handle 9 is turned counterclockwise to drive the wiper 4 to rotate. The rotation of the wiper 4 drives the lens 2 to rotate. When the lens 2 rotates to a certain extent, the blocking rod 6 blocks the locking hook 5, so that the lens 2 cannot move left and right or rotate counterclockwise.

[0027] When the left side of the lens 2 is not clear, the handle 9 continues to be turned counterclockwise, the lens 2 does not move, and the wiper 4 rotates relative to the lens 2 to clean the lens 2.

[0028] When the material enters the lens barrel 1, turn the handle 9 clockwise to move the lock hook 5 away from the blocking rod 6, push the handle 9 to the left, and the lens 2 moves to the left to push the material out of the lens barrel 1; after the material is pushed out of the lens barrel 1, pull the handle 9 to the right to pull the lens 2 back to the left end of the lens barrel 1, and turn the handle 9 to clean the left end of the lens 2.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
