Description

The utility model relates to seabed autonomous seismic stations and is intended for recording seismic signals during engineering seismic surveys.

A bottom seismic station is known, containing a housing in the opening of which there is a pressure-tight connector with electrical communications connected to it (see patent RU No. 206397U1, pub., 09/08/2021).

The known bottom module has a sealed housing with protective elements that protect the housing from mechanical damage, as well as an electrical sealed connector connected to control and recording units via electrical communications, allowing for the reception, processing and recording of seismic vibrations.

A disadvantage of the known bottom seismic station is the high probability of obtaining unreliable results associated with insufficient sealing of the housing due to the failure of its electrical sealed connector (for example, as a result of mechanical damage).

The technical problem is to create an engineering bottom seismic station that is reliable in use and provides reliable results.

The technical result is to increase the performance of the station by ensuring the tightness of its housing even if the sealed connector cover is damaged. That is, even in the absence of a sealed connector cover, water is not able to penetrate into the station housing and cannot irreversibly damage the equipment inside the housing, as well as the already recorded seismic data.

The technical problem is solved, and the technical result is achieved by the fact that in a bottom seismic station containing a housing, in the hole of which there is a pressure-tight connector with electrical communications of the station connected to it, according to the utility model, the pressure-tight connector has a protrusion located in the hole of the case, as well as a flange with a mating plane in contact with the outer surface of the station body and connected to it using threaded elements, an electrically insulating holder is installed in the internal through hole of the sealed connector, in the holes of which electrical communication plugs are located, the ends of which are located in a recess open on the outside of the sealed connector and intended for placement in the indicated recess of the external element with sealing rings, while the holder is made with a ledge, installed in the hole on the side of the body, sealed by means of the holder's sealing rings and pressed with its ledge to the sealed connector using a nut, the plugs are installed in the holes of the holder by means of sealing rings, the ledge of the sealed connector is sealed in the housing openings using protrusion sealing rings, and a sealing gasket is located between the flange mating plane and the housing surface.

The utility model is illustrated with the help of drawings.

In fig. 1 shows a view of the bottom station from the side of the sealed connector;

In fig. 2 - section A-A in Fig. 1.

The described bottom engineering seismic station. contains a housing 1, in the hole 2 of which there is a sealed connector 3 with electrical communications of the station connected to it. The sealed connector 3 has a protrusion 4 located in hole 2 of the housing 1, as well as a flange 5 with a mating plane 6 in contact with the outer surface of the station housing 1 and connected to it using threaded elements 7. An electrically insulating holder 8 is installed in the internal through hole of the sealed connector 3. in the holes of which there are plugs 9 electrical communications. The ends of the plugs 9 are located in the recess 10, open on the outside of the sealed connector 3. The recess 10 is intended to accommodate the external element 11 with sealing rings 12. The drawing shows the cover (plug) of the sealed connector 3 as the external element 11, but a socket can also be used electrical connector (not shown in the drawings). In this case, the holder 8 is made with a ledge 13, installed in the hole of the sealed connector 3 from the side of the housing 1, sealed by means of O-rings 14 of the holder 8 and pressed with its ledge 13 to the sealed connector 3 using a nut 15. A pressure washer 16 can be installed between the nut 15 and the holder The plugs 9 are installed in the holes of the holder 8 by means of sealing rings 17. The protrusion 4 of the sealed connector 3 is sealed in the hole 2 of the housing 1 using the sealing rings 18 of the protrusion 4, and between the mating plane 6 of the flange 5 and the surface of the housing 1 there is a sealing gasket 19.

The drawing also shows the nut 20 of the external element 11 of the bayonet connection with a groove interacting with the pin 21 of the sealed connector 3, as well as the gasket 22 and the locking ring 23.

An important condition for the operation of stations at the bottom of the water area is to ensure their autonomy and maintain the required duration of data recording, depending on the assigned tasks. If the seal of the station body is damaged, its electrical components may fail and the already recorded data may be lost. One of the components that can lose its seal is the housing seal. To increase its reliability, a hermetic connector has been developed, which helps to increase the degree of safety of equipment inside the station housing.

Hermetic connector 3 is protected by a plug when operating under water (external element 11), through which, through plugs 9, the battery is charged, communicated with control software, tested and adjusted the station clock using a GPS/GLONASS antenna, and read information.

O-rings 18, 17, 14 and 12, as well as gasket 19 ensure the tightness of the elements they seal. The holder 8 serves for positioning and placement of plugs 9 that provide electrical contact. The nut 15 holds the pressure washer 16, which ensures the retention of the holder 8 with the plugs 9 installed in it in the sealed connector 3. The nut 20 is equipped with grooves for bayonet engagement with the pins 21 and ensures the retention of the external element 11 in the recess 10 of the sealed connector 3. The gasket 22 with a locking ring 23 serves for fixing the nut 20 on the external element 11. Threaded elements 7 secure the sealed connector 3 in the housing 1.

Rubber seals (rings) 17 are used for each plug 9 (pin contact), and the use of filling compounds is eliminated, which ensures the maintainability of the sealed connector 3 and the ability to withstand water pressure corresponding to the maximum working depth of the station. This circumstance makes it possible to maintain its tightness even if the external element 11 is damaged. That is, even if the external element 11 is leaky or absent, water is not able to penetrate into the station housing and cannot irreversibly damage the equipment inside the housing, as well as the recorded seismic data.

The tightness of the station is constantly monitored based on readings from pressure, temperature and relative humidity sensors located inside it. Exceeding the readings of monitored parameters is signaled by the display module with a special color sequence.

The prepared station with a hermetic connector 3, into which the outer element 11 (plug) is tightly installed and fixed with a nut 20, is lowered to a working depth of up to 200 m. After finishing work at the bottom and lifting it, the station is washed from the outside with fresh water and dried. The status of the station is assessed by the color sequence of light flashes of the display module through the translucent plug of the vacuum port 24.

The hermetic connector plug 3 is removed and another external element 11 with a harness is connected to the hermetic connector, providing connection between the station and the device for charging batteries, reading seismic data and setting its operating parameters.

Thus, a station with the described hermetic connector design has increased reliability in use and ensures reliable results.
