Description

The invention relates to the field of fiber optic systems, in particular to energy transmission via optical fiber, and can find application in optical energy transmission systems for power supply of remote electronic, optoelectronic and electromechanical devices (PoF technology), which receive power supply using an optical fiber and a photoelectric converter.

The design of a photoelectric converter module is known, providing a connection between an optical fiber and a photocell for transmitting optical energy (US10553736, published 01/05/2017). This device has a number of disadvantages, namely, the known module does not have a sealing system when the optical fiber is opened, which does not allow servicing it in the field. In addition, the disadvantages are the inability to effectively remove heat without additional systems due to the design of the housing, as well as the low transmitted optical power.

A device for plug-in connection of optical fibers is also known, providing transmission of optical power up to 70 W in continuous lasing mode (UA 26369, published on August 30, 1999). The disadvantage of this device is its difficulty in operation, lack of operator protection and the need to ensure cleanliness during maintenance, which requires qualifications to use it, which excludes the possibility of servicing it in the field.

No photoelectric converter modules of similar designs are known from the prior art that would protect the optical cable and photoelectric element from contamination leading to their failure, as well as protecting the user from damage from optical radiation.

The technical problem consists of creating conditions that ensure protection of the optical cable and photovoltaic element from contamination leading to their failure, as well as protection of the user from damage by optical radiation.

The technical result is the creation of a photoelectric converter module design that provides protection of the optical cable from contamination and protection of users from optical radiation by sealing the detachable assembly for the optical cable by simultaneously closing the diaphragms of both parts of the assembly when it is opened.

The specified technical result is achieved in that the photoelectric converter module with a detachable unit for an optical cable contains a casing, inside of which there is a photoelectric element, a detachable unit for an optical cable installed on the casing, which consists of two parts.

The first part of the assembly is fixed to the module casing, contains a cylindrical body with a hole for the optical beam, an inner ring with pins evenly spaced around the hole, as well as an outer ring and a pressure plate; the petals of the first diaphragm are installed on the said inner ring with the possibility of their rotation around the axes of the pins , ensuring the closing and opening of the petals for closing and opening the first diaphragm, the outer and inner rings are made with the possibility of mutual fixation by snapping when the petals of the first diaphragm are closed.

The second part of the detachable module assembly contains a cylindrical body with a central channel for fixing the optical cable, inner and outer rings and a pressure plate, the inner ring is made with pins on which the petals of the second diaphragm are fixed with the possibility of their rotation around the axes of the pins, and the cylindrical pins are fixed on these pins crowns for engagement with the mating pins of the inner ring of the first part of the assembly.

In this case, the housings of the first and second parts of the detachable assembly are made with the possibility of mutual fixation with a bayonet connection, the housings of the detachable assembly are made with grooves and spring-loaded clamps for making a bayonet connection.

As a result of the presence of tightly closing diaphragms on both parts of the detachable assembly, when the fasteners of the detachable assembly are rotated, the diaphragms are simultaneously closed under the influence of the mutual rotation of both parts of the assembly. Rotation of the “twisted” part of the detachable assembly leads to rotation of the interlocking moving elements - diaphragm petals - relative to the outer parts of the connection. Thus, when the detachable assembly is disconnected, the diaphragms are closed by the petals, and when connected, they are forced to open.

The invention is illustrated by the following figures.

In fig. Figure 1 shows a sectional view of the module.

In fig. 2 shows the first part of the detachable assembly.

In fig. 3 shows the second part of the detachable assembly.

Fig. 4a) and 4b) demonstrate the elements of the bayonet connection.

In fig. 5 shows the aperture blade.

In fig. Figure 6 shows the inner ring of the diaphragm without cylindrical crowns.

In fig. Figure 7 shows the outer diaphragm ring.

In fig. 1-7 shows the following structural elements of the module:

1 - outer ring of the diaphragm of the second part of the detachable assembly;

2 - inner ring of the diaphragm of the second part of the detachable assembly;

3 - channel for the optical cable of the second part of the detachable unit;

4 - cylindrical body of the second part of the detachable assembly;

5 - pressure plate of the diaphragm of the first part of the detachable assembly;

6 - pressure plate of the diaphragm of the second part of the detachable assembly;

7 - diaphragm blades of the second part of the detachable assembly;

8 - cylindrical crowns connecting the pins of both diaphragms;

9 - diaphragm blades of the first part of the detachable assembly;

10 - outer ring of the diaphragm of the first part of the detachable assembly;

11 - inner ring of the diaphragm of the first part of the detachable assembly;

12 - cylindrical body of the first part of the detachable assembly;

13 - diaphragm hole for the passage of the optical beam;

14 - radiator fins of the module casing;

15 - photovoltaic cell crystal;

16 - module casing;

17 - flat springs;

18 - protrusions of the bayonet connection;

19 - grooves of the bayonet connection;

20 - deepening of groove 19;

21 - pin of the inner diaphragm ring;

22 - protrusion for fixing the inner ring of the diaphragm along the vertical axis when aligned with the outer ring;

23 - hole through which the optical beam passes in the open state of the diaphragm, and which is closed by the triangular parts of the blades 7,9 in the closed state;

24 - oval hole of the petals 7,9, in which the pin 21 of the inner ring is placed and serves to rotate the petals around the axis of the pin 21;

25 - protrusion of the petal 7, 9, moving along the groove 19 of the outer ring;

26 - triangular section of the blade 9, covering the hole 13 of the diaphragm;

27 - hole in which the inner diaphragm ring is located;

28 - optical cable.

The bayonet connection includes two elements. The element shown in figure 4a is made with three flat springs 17 with protrusions 18 at the ends. The element shown in figure 4b has three corresponding grooves 19 on its side surface, ending with a recess 20.

The bayonet connection of the parts of the detachable assembly is carried out in the following order.

The protrusions 18 of the bayonet connection enter the grooves 19, passing their vertical parts until they stop. The rotation of one element relative to the other leads to the protrusions 18 getting into the recesses 20 of the groove 19. This connection ensures the fixation of the first part of the detachable assembly on the second.

Opening the detachable unit of the photoelectric converter module is carried out as follows.

To open the detachable assembly, rotate the second part of the detachable assembly (Fig. 3) relative to the first (Fig. 2) until it stops. In this case, the internal rings 2.11 of the diaphragms rotate. With the help of cylindrical crowns 8, mutual rotation is ensured by the engagement of pins 21 of both inner diaphragm rings, because cylindrical crowns 8 provide adhesion to the mating pins of the inner rings of the two parts of the assembly. In this case, the movement of the pins 21 leads to the movement of the petals 7.9 along the grooves 19 of the outer rings 1.10 of the diaphragms until they close tightly. The closed petals 7.9 act as sealing elements in the open state of the detachable unit, tightly closing the gap between the petals 7.9.

This protects the optical cable 28 from contamination and users from optical radiation by simultaneously closing the diaphragms of both parts of the detachable assembly when it is opened.
