[0019] The principle and characteristics of the application are described below in conjunction with the drawings, and the examples are only used to explain the application and not to limit the scope of the application.
[0020] As Figure 1 , a waterproof manhole door, including straight cylinder 1, the straight cylinder 1 is provided with flange 2, the inner diameter of the flange 2 is connected with the outer diameter end of the straight cylinder 1, the outer surface of the flange 2 is lower than the end of the straight cylinder 1;Sealing gasket 3 is arranged between the straight cylinder 1 and the flange 2;The upper surface of the straight cylinder 1 and the flange 2 is provided with outer baffle door 4;The inner surface of the outer baffle door 4 is matched with the shape of the straight cylinder 1, the outer edge of the outer baffle door 4 is matched with the shape of the flange 2;The outer baffle door 4 is connected with the flange 2 through fastener 5.
[0021] The outer baffle door 4 includes handle 41 and outer baffle 42. The handle 41 is vertically fixed on the outer baffle 42, the number of the handle 41 is multiple, and the handle 41 is symmetrically arranged on both sides of the center line of the outer baffle 42. The shape of the outer baffle 42 is outwardly convex, and the bolt hole size on the outer baffle 42 is matched with the bolt hole size of the flange 2.
[0022] One end of the straight cylinder 1 is fixed on the wall plate of the equipment, the length of the straight cylinder 1 is 100-500mm, and the material of the straight cylinder 1 is one of metal or non-metal.
[0023] The flange 2 is fixed to one end of the straight cylinder 1 away from the equipment wall panel. The end of the straight cylinder 1 is 10-100mm higher than the top of the flange 2. The flange 2 is made of either metal or non-metal.
[0024] The internal dimension of the protruding outer baffle door 4 is 1-50mm larger than the external dimension of the straight cylinder 1.
[0025] Manhole doors using this method reduce dependence on manufacturers, expand the selection of sealing gaskets, eliminate the possibility of water leakage, and ensure that manhole doors can be used normally even in heavy rain without affecting the normal operation of the equipment.
[0026] The outer baffle door 4 has a structure that can be either multi-layered or single-layered.
[0027] like Figure 2 The outer baffle door 4 shown only includes the outer baffle 42, and this type of manhole door is used for normal temperature conditions. However, if the equipment is in a high-temperature condition, the outer baffle door 4 can be made into a double-layer structure.
[0028] like Figure 3 As shown, a partition 43 is added inside the outer baffle door 4, and thermal insulation material 44 is filled between the partition 43 and the outer baffle 42.
[0029] The outer baffle door 4 is square, round, elliptical or spherical in shape.
[0030] When the outer baffle door 4 adopts the above shape, it can be selected according to the installation space and the pressure resistance level of the equipment, thereby increasing the variety of choices for manhole doors.
