[0043] The working principle of the present application is that when people want to maintain the roof machinery, the building roof machinery drying maintenance device can be used. First, the user places the roof machinery on the intermittent rotation mechanism 6, and the roof machinery contacts the fixing mechanism 8, thereby driving the fixing mechanism 8 to operate. The fixing mechanism 8 clamps the roof machinery. Then the user pours the cleaning agent into the liquid storage tank 3. The cleaning agent flows through the liquid storage tank 3 and the water outlet pipe 4 into the intermittent water outlet mechanism 5, and then flows onto the roof machinery, so that the cleaning agent cleans the roof machinery. The intermittent water outlet mechanism 5 drives the intermittent rotation mechanism 6 to operate, and the intermittent rotation mechanism 6 drives the roof machinery to rotate, so that the cleaning agent can cover the roof machinery. The cleaning agent flowing on the roof machinery is absorbed by the drying wiping mechanism 7, so that the roof machinery remains dry and prevents the roof machinery from rusting due to moisture. After the roof machinery is cleaned, the user stops pouring the cleaning agent. Then the user reverses the operation of the intermittent water outlet mechanism 5, which drives the intermittent rotation mechanism 6 and the drying wiping mechanism 7 to operate in reverse. Then the user takes the roof machinery out of the intermittent rotation mechanism 6, and the roof machinery is separated from the fixing mechanism 8, so that the fixing mechanism 8 operates in reverse to return to the original position.

[0044] After the user places the roof machinery on the intermittent rotation mechanism 6, the user pours the cleaning agent into the liquid storage tank 3. The cleaning agent flows through the liquid storage tank 3 and the water outlet pipe 4 into the water storage frame 53. When the cleaning agent in the water storage frame 53 continuously increases, it drives the water storage frame 53, the first shaft 52 and the first protrusion 54 to rotate downward. When the water storage frame 53 rotates downward to a certain extent, the cleaning agent flows out of the water storage frame 53, so that the cleaning agent flows onto the roof machinery and cleans the roof machinery, thereby keeping the roof machinery clean. After the roof machinery is cleaned, the user stops pouring the cleaning agent, which loses the force of the cleaning agent, so that the water storage frame 53 stops rotating downward. Then the user rotates the first protrusion 54 upward, which drives the water storage frame 53 and the first shaft 52 to rotate upward.

[0045] After the user places the roof machine on the rotating disc 69, when the first protrusion 54 rotates downward, the first protrusion 54 rotates downward to contact and cooperate with the pressing rod 62, thereby driving the pressing rod 62 to move downward, the first spring 63 is compressed, the pressing rod 62 releases the pull rope 64, the sixth spring 671 in the stretched state resets, thereby driving the rack 66 to move forward, the rack 66 cooperates with the one-way gear 610, thereby driving the one-way gear 610 and the rotating disc 69 to rotate, the rotating disc 69 drives the roof machine to rotate, so that the cleaning agent can cover the roof machine, reduce the cleaning dead angle, and at the same time, the step of pushing the roof machine by the user is saved, when the first protrusion 54 rotates downward to separate from the pressing rod 62, the first spring 63 resets, thereby driving the pressing rod 62 to move upward, the pressing rod 62 pulls the pull rope 64, the pull rope 64 drives the rack 66 to move backward, the sixth spring 671 is stretched, the rack 66 cooperates with the one-way gear 610, so that the one-way gear 610 idles, and the above-mentioned action can be repeated to clean the roof machine multiple times.

[0046] After the user places the roof machine on the rotating disc 69, the wiper 41 contacts the roof machine, when the cleaning agent flows on the roof machine, the wiper 41 sucks the cleaning agent on the roof machine, when the rotating disc 69 rotates, the rotating disc 69 rotates to contact and cooperate with the protrusion rod 72, thereby driving the protrusion rod 72 to move outward, the second spring 73 is compressed, the protrusion rod 72 drives the connecting rod 74 and the wiper 41 to move outward, the wiper 41 moves outward to contact and cooperate with the dehumidification block 76, thereby driving the dehumidification block 76 to move outward, the third spring 77 is compressed, the dehumidification block 76 extrudes the wiper 41, so that the cleaning agent flows out of the wiper 41 and falls on the ground, so that the roof machine remains dry, preventing the roof machine from rusting due to dampness, after the rotating disc 69 rotates to separate from the protrusion rod 72, the second spring 73 resets, thereby driving the protrusion rod 72, the connecting rod 74 and the wiper 41 to move inward, after the wiper 41 moves inward to separate from the dehumidification block 76, the third spring 77 resets, thereby driving the dehumidification block 76 to move inward to the original position.

[0047] After the user places the roof machine on the rotating disc 69, the roof machine will press on the pressing block 81, and will be affected by the weight of the roof machine itself, thereby driving the pressing block 81 and the fixer 82 to rotate inward, the fourth spring 83 is twisted and deformed, the fixer 82 rotates inward to contact the roof machine, so that the fixer 82 clamps the roof machine, preventing the roof machine from falling on the ground during cleaning, after the user takes out the roof machine from the rotating disc 69, the roof machine separates from the pressing block 81, the fourth spring 83 resets, thereby driving the pressing block 81 and the fixer 82 to rotate outward to the original position.

[0048] In order to avoid the cleaning agent flowing all the time, before pouring the cleaning agent, the user installs the compression pipe 91 on the water outlet pipe 4, after the installation of the compression pipe 91, the user pours the cleaning agent into the liquid storage tank 3, when the cleaning agent flows on the closer 93, the closer 93 blocks the flow of the cleaning agent, when the user wants to clean the roof machine, the user rotates the closer 93, thereby opening the channel of the compression pipe 91, the cleaning agent flows through the liquid storage tank 3, the water outlet pipe 4 and the compression pipe 91 and falls on the water storage frame 53, thereby controlling the flow of the cleaning agent, after the cleaning of the roof machine is completed, the user reversely rotates the closer 93, the closer 93 closes the channel of the compression pipe 91, so that the cleaning agent cannot fall on the water storage frame 53.

[0049] When the user wants to add the cleaning agent, the user rotates the opening and closing plate 101, the opening and closing plate 101 drives the second rotating shaft 104 to rotate, the fifth spring 103 is twisted and deformed, after the opening and closing plate 101 is rotated to the specified position, the user controls the opening and closing plate 101 to stay, then the user pours the cleaning agent into the liquid storage tank 3, thereby adding the cleaning agent in the liquid storage tank 3, after the addition of the cleaning agent is completed, the user releases the opening and closing plate 101, the fifth spring 103 is reset, thereby driving the opening and closing plate 101 and the second rotating shaft 104 to rotate to the original position, the opening and closing plate 101 shields the liquid storage tank 3, preventing the dust from falling into the liquid storage tank 3, thereby preventing the cleaning agent from being polluted, reducing the use effect of the cleaning agent.

The scope of the following claims is to be accorded the widest patent protection legally permissible under the patent statutes.
