Abstract
The utility model relates to a construction device cabinet capable of balancing internal and external pressure, comprising a cabinet casing and a through hole on the cabinet casing. The utility model is characterized in that the inner of the cabinet casing is provided with liquid medium, and the through hole is provided with an internal and external isolating device. The internal and external isolating device on the through hole is an isolating membrane which is fixed at the periphery of the through hole by a pressing membrane ring. The internal and external isolating device on the through hole is a connection pipe whose top end is connected with a flexible capsule, and the tail end of the connection pipe is connected with the through hole. The internal and external isolating device on the through hole is a piston positioned in the through hole whose inner wall is provided with a sealing ring matching with the piston. The utility model uses the simple structure to balance the internal and external pressure difference of the underwater deep operation device.
Description
Technical field
The utility model relates to a kind of construction equipment casing, particularly a kind of construction equipment casing of energy balance external and internal pressure.
Background technology
Present application along with urban construction and development and ocean engineering, the thing followed is that the degree of depth of operation under water is increasing, existing construction equipment suffered pressure in water is also more and more higher, in order to bear bigger pressure under water, the casing of equipment also constantly increases, used material is also more and more thicker, and especially the requirement of the various seals of equipment also increases.Cause the manufacturing cost of equipment to rise.
Summary of the invention
The purpose of this utility model is that the construction equipment of degree of depth operation is in order to bear bigger pressure under water under water in the solution prior art, and the casing of equipment also constantly thickens, and especially the requirement of the various seals of equipment also increases.Cause the manufacturing cost of the equipment existing problem that rises, a kind of construction equipment casing that can be equilibrated at the equipment external and internal pressure difference of degree of depth operation under water is provided.The construction equipment casing of a kind of energy of the utility model design balance external and internal pressure comprises the through hole on tank shell, the tank shell, it is characterized in that: liquid medium is arranged in tank shell, inside and outside spacer assembly is arranged on through hole.Inside and outside spacer assembly on the through hole is one deck barrier film, and barrier film is fixed on the through hole periphery by the press mold ring.Inside and outside spacer assembly on the through hole is the tube connector that a top is connected with flexible pocket, and the end of tube connector connects through hole.Inside and outside spacer assembly on the through hole is the piston that is positioned at through hole, and the sealing ring that cooperates with piston is arranged on the through hole inwall.The utility model has the advantages that with simple structure and incite somebody to action the equipment external and internal pressure difference balance of degree of depth operation under water.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is a barrier film structural representation of the present utility model,
Accompanying drawing 2 is a flexible pocket structural representation of the present utility model,
Accompanying drawing 3 is a piston structure schematic diagram of the present utility model,
The specific embodiment
Comprise the through hole 2 on tank shell 1, the tank shell 1 among Fig. 1,2,3, it is characterized in that: liquid medium 3 is arranged in tank shell 1, inside and outside spacer assembly is arranged on through hole 2.Inside and outside spacer assembly among Fig. 1 on the through hole 2 is one deck barrier film 4, and barrier film 4 is fixed on through hole 2 peripheries by press mold ring 5.Inside and outside spacer assembly among Fig. 2 on the through hole 2 is the tube connector 7 that a top is connected with flexible pocket 6, and the end of tube connector 7 connects through hole 2.Inside and outside spacer assembly among Fig. 3 on the through hole 2 is the piston 8 that is positioned at through hole 2, and the sealing ring 9 that cooperates with piston 8 is arranged on through hole 2 inwalls.In use, tank shell 1 sinks in the deep water, and extraneous hydraulic pressure is passed in the tank shell 1 by inside and outside spacer assembly, the balance inside and outside differential pressure that caves in of the barrier film 4 among Fig. 1.Flexible pocket 6 among Fig. 2 is flattened, and liquid medium 3 wherein flows back to tank shell 1, balance inside and outside differential pressure.Piston 8 is subjected to extraneous hydraulic pressure and bounces back among Fig. 3, balance inside and outside differential pressure, and sealing ring 9 has been isolated inside and outside medium.
So embodiment can finish tandem-driving bogie housing inside and outside differential pressure in above-mentioned three, makes whole subaqueous construction equipment be in no artesian condition, and the production requirement of apparatus casing and seal is reduced greatly.
