[0002] Currently, in order to facilitate the treatment of sewage, equipment such as agitators or flow promoters need to be added to sewage tanks. Therefore, after the tank is sealed and covered, the maintenance and repair of the equipment becomes difficult or impossible. If holes are made directly in the membrane cover of the sewage tank, the aesthetics will be greatly reduced, and the service life of the membrane cloth used to cover the inspection port will be shortened.

[0003] A patent publication number CN212104490U was found, entitled "A Maintenance Port Structure for Facilitating the Lifting of a Flow Pump in a Sewage Tank." The patent specifically discloses a maintenance port structure for facilitating the lifting of a flow pump in a sewage tank. Its features include a window frame, a window leaf frame, and a support frame. The window leaf frame is a casement window structure composed of two half-frames. One side of each half-frame is hinged to the window frame, and the other side of each half-frame can be movably brought closer together or separated. The window frame is mounted on the support frame, which is connected to a walkway panel.

[0016] A window opening device for facilitating the lifting of components in a sewage tank includes a sewage tank top cover 1, a baffle 16, a walkway 2 on the sewage tank top cover 1, and a window 3 located on the edge of the sewage tank top cover 1, the edge of the sewage tank top cover 1 being an inclined structure; a column 4 located on the walkway 2, a support plate 6 and a suspension frame 13 on the column 4, a rope roller 11 on the support plate 6, a pull rope 5 wound on the rope roller 11, a fixed pulley 17 on the suspension frame 13, the pull rope 5 passing over the fixed pulley 17 and connecting to the rope roller 11; and a window opening mechanism including a hand crank 12 connected to the rope roller 11, the other end of the pull rope 5 being connected to the upper edge of the window 3.

[0017] In this embodiment, the sewage tank cover 1 is installed on the top of the sewage tank. To facilitate the access or maintenance of sewage treatment equipment, several windows 3 are provided on the sewage tank cover 1. The lower end of the windows 3 is connected to the sewage tank cover 1 by hinges. To facilitate opening the windows, a column 4 is provided on the walkway 2. The column 4 is provided with a support plate 6 and a hanging frame 13. A rope roller 11 is provided on the support plate 6. The rope roller 11 is connected to a hand crank 12. A fixed pulley 17 is provided on the hanging frame 13. A pull rope 5 is wound on the fixed pulley 17 and the rope roller 11. By cranking the hand crank 12, the window 3 can be opened by pulling the rope 5. Example

[0018] The bottom of the column 4 is fixed on the walkway 2. The support plate 6 is horizontally set. The support plate 6 is equipped with a rope roller frame 7. The two ends of the rope roller 11 are connected to bearings and are connected to the hand crank 12 through the bearings.

[0019] Unlike the above embodiments, in this embodiment, the column 4 is fixed on the walkway 2, the support plate 6 is set horizontally, the structure of the rope roller frame 7 is two vertically set plates, the bottom is connected to the support plate 6, and the two ends of the rope roller 11 are provided with bearings, which are connected to the hand crank 12. Example

[0020] The fixed pulley 17 on the suspension bracket 13 is higher than the upper edge of the window 3, and one end of the pull rope 5 is fixedly connected to the upper edge of the window 3.

[0021] Unlike the above embodiments, in this embodiment, in order to save pulling force, the hanging bracket 13 is set higher than the upper edge of the window 3, and the pull rope 5 is set at an angle. Example

[0022] The suspension bracket 13 has a socket 8 on its side, a plug plate 9 is provided in the socket 8, a stop bar 10 is provided on the upper surface of the plug plate 9, the upper end of the stop bar 16 is higher than the top of the hand crank 12, and the stop bar 16 is in contact with the hand crank 12 in the vertical plane.

[0023] Unlike the above embodiments, in this embodiment, the outer side of the suspension frame 13 is provided with a socket 8, the socket 8 is connected to a plug plate 9, and a stop bar 10 is provided on the plug plate 9. By providing the stop bar 10, the hand crank 12 can be fixed to prevent the rope from coming off during operation. Example

A spring 15 is provided between the baffle 16 and the suspension frame 13. The spring 15 is fixedly connected to the baffle 16 and the suspension frame 13.

[0025] Unlike the above embodiments, in this embodiment, in order to make it convenient to lower the window 3, a guide rod 14 is provided on the hanging frame 13, and a baffle 16 is provided at the end of the guide rod 14. A spring 15 is provided between the baffle 16 and the hanging frame 13. The spring 15 plays a buffering role and can also prevent the window 3 from being too open, which would make it inconvenient to close the window 3.

[0026] The working method (or working principle) of this utility model: When this technology is in operation, if it is necessary to open the window to hoist the propeller, first pull out the insert plate 9, then manually operate the hand crank 12 to rotate. The hand crank 12 drives the rope roller 11 to rotate, and the rope roller 11 pulls the pull rope 5 to realize the rope winding action. At this time, the window 3 is slowly opened. When the window 3 touches the baffle 16, the rope winding action can be stopped. The top plate can also play a positioning role. Insert the insert plate 9 into the insertion hole 8. After the hand crank 12 rotates at most one revolution, it will contact the baffle 10 to achieve the fixing effect.

[0027] Then operate the lifting and installation of the propeller. After the propeller is installed, hold the hand crank 12, pull out the insert plate 9, and then operate the rope release action. After the window 3 is completely closed, insert the insert plate 9 into the socket 8.
