Description

A sealed tank with a cooling and electrical switching terminal for testing the operation of a ship's antenna during climatic tests

The utility model relates to testing equipment, namely to equipment for testing and can be used for climate testing with monitoring the operation of various devices, for example, antennas of deep-sea vehicles.

The purpose of the utility model is to provide control of the parameters of the operation of a ship’s antenna (SC) during climatic tests by using a cooling terminal and electrical switching to connect the liquid cooling system and electrical connections of the SC to an external cooling system and a stand for monitoring the functioning parameters.

A terminal (Eng. Terminal - “final”) is the final part of a certain system that provides a connection between the system and the external environment. Free Encyclopedia Wikipedia.

For the prototype, a device was selected in the form of a sealed reservoir, a cover with a seal, and a removable fitting and plug system included in the system for checking the tightness of the device according to the patent of the Russian Federation for utility model No. 88444, 2009, IPC ⁸ G01M 3/02 2009, publ. . Bull. No.31, 2009

The disadvantage of the prototype device is the inability to control the operation of the device during climatic tests, i.e. the impossibility of testing the device in the on state with a connection to an external cooling system and a stand for monitoring operating parameters.

The problem to which the utility model is directed is as follows.

In the manufacture of various devices, for example, ship antennas (SC) of deep-sea vehicles, after assembly, adjustment, and mechanical tests, it is necessary to carry out climatic tests (high and low temperature, thermal shock, high humidity, sea and salt fog).

Due to the design features, the bottom flange of the spacecraft body is open for electrical and hydraulic (liquid cooling system) connections to adjacent devices at the facility, therefore, to ensure the spacecraft’s tightness in order to prevent the failure of radio electronic units (EW) under the influence of various climatic factors, it is installed in a sealed reservoir with an upper central hole (for installation of the device), while the shank of the lower flange of the housing is sealed with standard rubber rings, i.e. simulate installation and sealing at the facility (second stage of a lifting mast).

Before conducting climate tests, to ensure the safety of the REB, the spacecraft is checked for leaks by the internal pneumostatic pressure, for this, the tank is provided with a removable air fitting, and the upper central hole is sealed with a cap with a shank and a seal similar to the shank and O-rings of the spacecraft.

When testing the tightness of the tank to the air nozzle, using a hose, connect a compressor or compressed air line through an air reducer with a manometer. They inject air into the device and create an excess pressure of 0.6 ati (kgf / cm ² ), shut off the air supply, maintain the set time (15-30 minutes) and release the pressure, while smoothly supplying, discharging and closing the air is carried out by an air reducer, and the pressure value is controlled by a manometer.

The tank is considered to have passed the pneumatic test if there was no pressure drop on the manometer, with an air supply shut off.

After testing the tank, the cover is removed and the air connection is replaced with a sealing plug.

The essence of the claimed technical solution lies in the fact that in a sealed tank with a terminal for cooling and electrical switching (TOEK) to test the operation of the ship's antenna (SC) during climatic tests, containing a cylindrical body with stiffeners on the side surface, a base with an opening for installing an air fitting or sealing plugs with at least two grooves on the side surface with o-rings, and an upper flange with a central hole for sealing boron and perimeter holes for mounting the device, as well as a removable cover for checking the tightness of the device itself in the form of a plate with mounting holes matching the holes in the upper flange and the sealing cylindrical shank with at least two grooves on the side surface with o-rings, similar to the sealing shank and sealing rings of the spacecraft,

the aforementioned TOEC is installed on the side surface of the body, consisting of a sealed panel with sealed inlet and outlet fittings for refrigerant connected inside the body to the inlet and outlet of the liquid cooling system of the spacecraft, and sealed electrical connectors (GER) of the external connection, similar to the connectors of the spacecraft, and connected to them inside the case.

In variants of the device, the input, output fittings and the TOER GER can be equipped with removable sealed plugs, the sealing rings can be made of the rubber mixture of the IRP.
