Abstract
The utility model discloses a kind of underwater research vehicle battery closed cabin air-tightness detection devices, are made of shell, air-channel system and circuit control system.Air-channel system completes inflatable and deflatable control, and circuit system completes the control and each parameter display control of air-channel system solenoid valve.Quick connector connection of the inflating port by quick connector and underwater research vehicle with check valve, air inlet are connected by quick connector with air pump when use.The pressure air that air pump provides is injected into underwater research vehicle battery closed cabin to be checked by the device, reach products air tightness purpose by air pressure numerical value change in the monitoring dwell time, air pressure numerical stability in dwell time, illustrate airtight good, air pressure numerical value reduces in dwell time, illustrates that product is airtight bad.After monitoring, air in battery closed cabin is discharged by setting gas vent.It is detected by the way that the quick-release connector of replacement different size is airtight to the underwater research vehicle battery closed cabin of different size.The utility model design science, structure are simple and convenient to operate, and improve the practicability of air-tightness detection device.
Description
Technical field
The utility model relates to underwater equipment technical fields, are a kind of underwater research vehicle battery closed cabin air-leakage test dresses
It sets.The device uses the air and the means such as pressure maintaining, detection to different size product battery closed cabin to be measured injection certain pressure
Airtightness detection is carried out to product battery closed cabin.
Background technique
Underwater research vehicle battery closed cabin is one of vehicle core component, and major function is isolation propeller battery
The contact with water of group, relevant control circuit plate, for internal components such as circuit boards, it provides installation site, provides each connector installation
Position is internal part heat dissipation etc., so can bear vehicle in the water pressure of design head and holding air-tightness is exactly battery
Closed cabin main technique requirements.
Currently, fewer and fewer suitable for underwater research vehicle battery closed cabin air tightness detection equipment in the market, product quality
It is irregular, it is difficult to meet the airtight detection demand of underwater research vehicle battery closed cabin.The design of the device is by replacing different rule
The quick-release connector realization of lattice is airtight to the underwater research vehicle battery closed cabin of different size to be detected, and is solved underwater portion and is set
The standby airtight detection difficult of battery closed cabin.
Summary of the invention
The purpose of this utility model is to provide it is a kind of can be to underwater research vehicle battery closed cabin air-tightness detection device.
The utility model discloses a kind of underwater research vehicle underwater research vehicle air-tightness detection devices, by shell, gas circuit system
System and circuit control system composition, by replacement different size crossover sub to different model underwater research vehicle battery closed cabin gas
Close property is detected.Wherein air-channel system completes inflatable and deflatable control, and circuit system completes the control of air-channel system solenoid valve
And each parameter display control.Quick connector connection of the inflating port by quick connector and underwater research vehicle with check valve when use,
Air inlet is connected also by quick connector with air pump.Air pump provide pressure air pass through after drying the device be injected into it is to be checked
Vehicle battery closed cabin reaches products air tightness purpose by air pressure numerical value change in the monitoring dwell time, in the dwell time
Interior air pressure numerical stability, illustrates airtight good, and air pressure numerical value is unstable, illustrates that product is airtight bad.After monitoring, pass through dress
Put air in port release battery closed cabin.
Because being suitable in the market, underwater research vehicle battery closed cabin air tightness detection equipment is fewer and fewer, and product quality is irregular
It is uneven, it is difficult to meet the airtight detection demand of underwater research vehicle battery closed cabin.The design of the device passes through replacement different size
Quick-release connector realization is airtight to the underwater research vehicle battery closed cabin of different size to be detected, and solves underwater portion equipment electricity
The airtight detection difficult of pond closed cabin.
Detailed description of the invention
A kind of underwater research vehicle battery closed cabin air-tightness detection device design schematic diagram of Fig. 1
Specific embodiment
The present apparatus is made of shell, air-channel system and circuit control system, and wherein air-channel system completes inflatable and deflatable control
System, circuit system complete the control and each parameter display control of air-channel system solenoid valve.After device powers on, fortune to be measured is set
Carry the device battery closed cabin dwell time.Gas source is accessed, vehicle battery closed cabin to be measured is started to inflate, normally opened two two at this time
Three-way electromagnetic valve 4 is in normally open, when pressure reaches setting numerical value, pressure switch 6 to intermediate relay 5 and digital display time after
10 signal of electric appliance, intermediate relay 5 work, and control normally opened two-position two-way solenoid valve 4 and cut off gas circuit, at this point, gas circuit is in pressure maintaining
State, digital display time relay 10 start timing.When reaching the dwell time, and when pressure is stablized, digital display time relay 10
Give time-delay relay 11 signal, time-delay relay 11 control again normal off two-position two-way solenoid valve 9 be delayed it is open-minded, to battery closed cabin
It deflates, time-delay relay 11 controls the closing end deflation of normal off two-position two-way solenoid valve 9 after reaching delay time again.When detection gas
When the air pressure deficiency of road, pressure switch 6 stops timing to 10 signal of digital display time relay.Band by replacement different size is unidirectional
Valve quick-release connector 8 realizes detect airtight to the underwater research vehicle battery closed cabin of different size.By monitoring the dwell time
Interior air pressure numerical value change reaches products air tightness purpose, the air pressure numerical stability within the dwell time, illustrates airtight good, air pressure number
It is worth unstable, illustrates that product is airtight bad.After monitoring, air in battery closed cabin is discharged by device gas vent.
