[0022] The present invention is further described below with reference to the accompanying drawings and embodiments:
[0023] Example 1: A waterproof door structure for a prefabricated cabin of power equipment, see Figures 1 to 6 , including a door frame 1 and a hatch 2, a connecting shaft 11 is installed on one side of the upper and lower ends of the inner cavity of the door frame 1, and the opposite ends of the two connecting shafts 11 are fixedly connected to the limit disk 12, and the outer sides of the two connecting shafts 11 are rotatably sleeved with a connecting cylinder 24, and the two connecting cylinders 24 are fixedly connected to a connecting rod 23;
[0024] The two U-shaped connecting seats 22 are slidably connected in the two slide grooves 21, and one end of the two connecting rods 23 is respectively rotatably connected to the two U-shaped connecting seats 22 through a rotating shaft. When working, one end of the connecting rod 23 is rotated and sleeved on the outer side of the connecting shaft 11 through the connecting tube 24, and the other end of the connecting rod 23 is slidably connected in the slide groove 21 through the U-shaped connecting seat 22, and the connecting rod 23 is rotatably connected to the U-shaped connecting seat 22, so that the hatch door 2 can be opened and closed perpendicular to the door frame 1, thereby avoiding the extrusion and wear of the rectangular sealing gasket 25 when the hatch door 2 is opened and closed, not only extending the service life of the rectangular sealing gasket 25, but also the hatch door 2 is vertically attached to the door frame 1, so that the rectangular sealing gasket 25 is forced between the door frame 1 and the hatch door 2, thereby improving the sealing of the connection between the hatch door 2 and the door panel, and further improving the waterproof effect of the hatch door 2.
[0025] For details, see Figure 2 and Figure 4 , there are insertion holes 13 on both sides of the inner cavity of the door frame 1, and a rectangular groove 26 is opened in the middle of the end of the hatch 2 away from the rectangular sealing gasket 25, and rectangular holes 28 are opened on both sides of the inner cavity of the rectangular groove 26. Insert blocks 29 are slidably connected in the two rectangular holes 28, and the ends of the two insert blocks 29 close to the insertion holes 13 are wedge-shaped. Two electric hydraulic cylinders 27 are installed in the inner cavity of the rectangular groove 26, and the driving ends of the two electric hydraulic cylinders 27 are respectively connected to the two insertion holes 13. When the hatch 2 is closed, the electric hydraulic cylinder 27 is started to push the insert block 29 to move and insert into the insertion hole 13, so that the hatch 2 can be automatically locked.
[0026] For further information, see Figure 3 and Figure 4 Pressure sensors 4 are installed on both sides of one end of the hatch 2 close to the rectangular sealing frame, and the two pressure sensors 4 correspond to the rectangular sealing frame. A controller is installed in the rectangular groove 26. The pressure sensor 4 is connected to the controller through a wire, and the controller is connected to the electric hydraulic cylinder 27 through a wire. When the hatch 2 is closed, the pressure of the rectangular sealing gasket 25 can be monitored through the pressure sensor 4. When the extrusion pressure of the rectangular sealing gasket 25 on the pressure sensor 4 is less than the set threshold, the electric hydraulic cylinder 27 is started by the controller to push the plug 29. Since one end of the plug 29 is wedge-shaped, the continuous movement of the socket 13 can improve the tight contact effect between the hatch 2 and the door panel. When the pressure sensor 4 reaches the set threshold, the electric hydraulic cylinder 27 is controlled by the controller to stop working, and then it can automatically adjust according to the tightness of the connection between the hatch 2 and the door panel, thereby ensuring the waterproof effect of the hatch 2.
[0027] It is worth noting that, see Figure 6A bearing 210 is provided in the inner cavity of the connecting cylinder 24. The bearing 210 includes an outer ring and an inner ring, and the outer ring and the inner ring are respectively connected to the connecting cylinder 24 and the connecting shaft 11. Through the setting of the bearing 210, the friction between the connecting cylinder 24 and the connecting shaft 11 is effectively reduced, which is conducive to personnel opening the hatch 2.
[0028] It is worth noting that see Figure 5 A rectangular block 33 is provided in the rectangular groove 26, and a fixing plate 3 is installed at one end of the rectangular block 33. Bolts 32 are passed through the four corners of the surface of the fixing plate 3, and the four bolts 32 are threadedly connected to the surface of the hatch 2. A sealing block 31 is installed on the fixing plate 3 outside the rectangular block 33. By screwing the bolts 32, it is convenient to install the fixing plate 3 on the outside of the rectangular groove 26, thereby facilitating the protection of the equipment in the rectangular groove 26, and cooperating with the sealing block 31 to increase the sealing performance of the contact between the fixing plate 3 and the hatch 2, thereby improving the waterproof effect of the connection between the fixing plate 3 and the rectangular groove 26.
