Detailed Description
In order to more clearly illustrate the contents of the present invention, the present invention will be further described with reference to the accompanying drawings and specific examples:
example 1
As shown in fig. 1-3, the novel watertight compartment structure according to the embodiment includes a cylinder 100 and an end cover 200, the cylinder 100 and the end cover 200 are both made of POM (polyoxymethylene), annular grooves 101 are respectively formed on outer walls of the cylinder 100 near two ends, so that annular fixing portions 102 are formed at two ends of the cylinder 100, an end cover 200 is fixed to both upper and lower openings of the cylinder 100 to form the watertight compartment, the end cover 200 includes an end cover body 201 and an annular fixing portion 202, the end cover body 201 and the annular fixing portion 202 are of a coaxial integrated structure, an annular step 203 is formed at a joint of the end cover body 201 and the annular fixing portion 202, the annular fixing portion 202 is embedded into the cylinder 100, at least one sealing ring 500 is fixed at a joint where an outer wall of the annular fixing portion 202 abuts against an inner wall of the cylinder 100 to improve water tightness, and a bolt 600 passes through bolt holes on the annular fixing portion 102 and the annular step 203 and is fixed by a nut 700. The existing watertight cabin is generally made of metal materials, and the end cover is generally fixed on the cylinder body directly by adopting screws. If the end cover and the cylinder made of the POM material are directly fixed by the screws, the looseness is easy to occur. For this reason, this embodiment is fixed through seting up annular groove 101, adopts bolt 600 and nut 700 cooperation, improves the installation steadiness.
The end cover that this embodiment relates to is divided into upper end cover and lower extreme cover, and the fixed part structure between upper end cover and lower extreme cover and the barrel is the same, and other parts set up as required.
The novel watertight cabin structure related to the embodiment is used for underwater equipment such as an underwater controller, an underwater LED lamp, an underwater robot and the like. The underwater equipment comprises a watertight cabin structure and a cylindrical circuit board 300, the bottom of the cylindrical circuit board 300 is fixed on a mounting hole 204 on an annular fixing part 202 through copper bolt columns 400 which are annularly arranged, a watertight connector 800 is hermetically mounted on an end cover, and the circuit board 300 is connected with shore-based control equipment or external equipment through the watertight connector 800. The underwater device in fig. 1-2 is used as an underwater controller, the upper end cover and the lower end cover of the underwater device are provided with watertight connectors in a sealing mode, the watertight connectors are only required to be arranged on the lower end cover of the underwater device in a sealing mode for structures such as an underwater LED lamp and an underwater robot, and the upper end cover is designed and improved according to requirements.
The existing circuit board is generally in a sheet shape, the bottom of the sheet circuit board is fixed on the lower end cover through copper bolt columns, and the circuit board can be broken near the fixed side after long-time use. Compared with a sheet circuit board, the bottom ring of the cylindrical circuit board 300 is fixed by a plurality of sites, and the structural stability is better. The number of the copper stud posts 400 according to the present embodiment is at least three. The circuit board 300 is generally fixed to the lower cap.
When the watertight cabin is used underwater, the pressure in the cabin is slightly lower than the external pressure, and the watertight cabin is difficult to open due to the negative pressure in the cabin. For this purpose, at least one end cover groove 205 is formed at the joint of the annular step 203 and the annular fixing portion 102, and the end cover grooves 205 are uniformly distributed around the joint of the annular step 203 and the annular fixing portion 102. When the cover is disassembled, the cover is pried open through the cover groove 205 on the cover 200 by using a straight screwdriver, so that air enters the cabin to realize the balance of internal and external pressure, and then the cover is easily opened, thereby maintaining or overhauling internal equipment. The end cap recess 205 is typically secured to the upper end cap, although it may be secured to the lower end cap.
