[0028] The utility model will be further explained in detail in combination with the drawings.

[0029] Embodiment 1

[0030] Referring to Figure 1 , a waterproof type sunwell wellhead structure of square cabin of this embodiment includes:

[0031] Sunroof cover, box body, sunroof eave and sunroof water baffle, the sunroof cover is fixedly installed to the top end of box body through hinge, the connecting place of sunroof cover and box body is equipped with lock catch, the top opening edge of box body is evenly distributed with multiple lock catch seats, the lock catch seat and the lock catch on sunroof cover one to one, the connecting place of lock catch seat and lock catch is equipped with adjusting bolt, for adjusting lock catch closing force, the sunroof water baffle is installed to the bottom edge of sunroof cover, the sunroof eave is welded to the edge at the top of box body.

[0032] Specifically,

[0033] As Figure 1 , Figure 5 , Figure 6 shown, first install the hinge 4, one end of the hinge 4 through the box 6 top opening edge inside the pre-drilled threaded hole with high-strength bolts, put the flat washer and spring washer under the bolt head and nut to prevent loosening, then the other end of the hinge 4 is fixed in the same way in the sunroof cover 1 edge, ensure the hinge 4 installation position accurate, using laser positioning instrument or high-precision mechanical clamp positioning, so that the sunroof cover 1 can be freely within the design range, after installation, install the reinforcing gasket at the hinge 4 and the box 6 and sunroof cover 1 connection part, then install the lock catch seat evenly distributed on the top opening edge of the box 6, fixed with bolt connection, after installation, install the sealing rubber around the lock catch seat, the rubber is embedded in the lock catch seat groove, when the operator pushes the sunroof cover 1 to close, the lock catch gradually approaches the lock catch seat on the box 6 with the movement of the sunroof cover 1. The hook-shaped structure of the lock catch first contacts the entrance of the lock catch seat, as the sunroof cover 1 continues to close, the lock catch gradually inserts along the groove of the lock catch seat under the action of a certain pushing force, when the sunroof cover is completely pressed against the sunroof 3, the lock catch 2 is completely inserted into the lock catch seat, the silicone rubber elastic sealing pad inside the lock catch begins to be extruded, and when it is extruded by the lock catch seat and the lock catch body, it can produce moderate deformation to fill the small gap between the lock catch and the lock catch seat. After the lock catch is completely inserted into the lock catch seat and the sealing pad is extruded, the lock catch reaches its designed closed position. At this time, the specific structure on the lock catch engages with each other, realizing the positioning of the lock catch in horizontal and vertical directions, preventing accidental displacement of the sunroof cover 1 in the closed state.

[0034] As Figure 2 , Figure 3 shown, the lock catch is installed on the sunroof cover 1, ensuring that the position of the lock catch corresponds to the lock catch seat accurately. Adjust the closing force of the lock catch by adjusting the bolt, install the sunroof water baffle 5, insert the water baffle along the groove on the bottom edge of the sunroof cover 1 and the inside edge of the top opening of the box 6, the groove depth is 5-10 mm and the width is 3-6 mm, ensuring that the water baffle is completely embedded in the groove and tightly contacts the bottom and side of the groove. Inject sealing glue into the groove, the sealing glue is special elastic sealing glue, such as silicone sealing glue, the amount of glue is calculated according to the volume of the groove, ensuring that it is filled completely without air bubbles and voids. After the sealing glue solidifies, check the installation firmness and sealing performance of the water baffle, which can be checked by water injection test at the connection between the water baffle and the box 6 and the sunroof cover 1.

[0035] The roof window eave is flat, and its length and width match the roof window of the box top. In order to effectively prevent water, the height of the roof window eave is increased by 10 cm higher than the height of the roof window cover. The roof window eave 7 is welded. A flat welding groove is pre-processed on the edge of the opening of the box top. The roof window eave is welded with the box by gas shielded welding. After welding, high-performance sealant is applied to the welding seam. When the rain falls, most of the rain will be blocked by the roof window eave, and cannot directly fall on the roof window cover. Even if a small amount of rain splashes at the joint between the roof window eave and the roof window cover, the sealant and the welding seam can prevent rain from seeping into the box from the connecting part, thereby achieving the effect of waterproofing. The roof window eave is made of stainless steel, which has high strength. The welding connection makes the roof window eave and the box form a whole, which can withstand external wind load, vibration and other forces. After installation, a buffer pad is installed on the surface opposite to the roof window cover 1, and the surface anti-skid texture faces upward.

[0036] As shown in Figure 4 Finally, a protective baffle is installed outside the connecting part between the box 6 and the roof window cover 1, and is fixed by bolts or welding. When the bolts are connected, the bolt spacing is designed according to the size of the protective baffle, and is generally 100-200 mm. The tightening torque meets the requirements. When welding, the length and height of the welding seam meet the design strength requirements. After welding, the protective baffle is checked for appearance to ensure that it is firmly and smoothly installed, without deformation and looseness.

[0037] When the rain falls on the roof window cover 1, the nano ceramic coating on the surface of the roof window cover 1 has good hydrophobicity, and the rain will quickly form water droplets and flow to the roof window eave 7 under the action of gravity. The inclination angle of the roof window eave 7 is 5 to 15 degrees, so that the rain can smoothly flow into the water guide groove. The semicircular cross section of the water guide groove and the hydrophobic coating accelerate the flow speed of the rain, so that it quickly flows to the outside of the shelter.

[0038] At the same time, when the roof window cover 1 is closed, the lock catch and the lock catch seat are tightly matched. The elastic sealing pad in the lock catch 2 is deformed by extrusion, filling the gap between the lock catch and the lock catch seat. The sealing strip further enhances the sealing effect, preventing rain from seeping in from the lock catch. The roof window water barrier 5 forms a continuous sealing line between the roof window cover 1 and the box 6, blocking rain from entering the gap between the two. Even in strong wind weather, rain is blown to the connecting part of the roof window cover 1 and the box 6, and multiple sealing structures can effectively prevent rain from seeping into the shelter.

[0039] The special sealed bearing connection of the hinge 4 allows the skylight cover 1 to displace or rotate within a certain range, to adapt to the deformation of the shelter under different environments, and the reinforcing gasket disperses the stress at the connection part of the hinge 4, to prevent the connection from loosening. The reinforcing ribs at the opening edge of the box body 6 enhance the strength of the connection part, to bear the opening and closing operation of the skylight cover 1 and external forces. The high-precision cooperation between the lock catch 2 and the lock catch seat and the fastening effect of the adjusting bolt ensure the stability of the skylight cover 1 in the closed state. The protective baffle protects the connection part from being impacted by external foreign matters, to further improve the stability of the structure.

[0040] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
