DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for releasing a compressed gas container filled with a compressed gas and having a perforated surface, and more particularly, to a container by penetrating a needle member through the perforated surface. The present invention relates to a compressed gas container release device capable of releasing a compressed gas in the container.

Conventionally, as a release device for releasing a compressed gas container, a manual type release device and an explosive type release device have been used.

[0003] The manual type release device manually penetrates a needle member through a perforated surface provided in a compressed gas container. The needle member may be a nail-shaped one or an injection needle. Is used. In addition, the manual release device often removes the needle member once penetrated by hand in order to improve gas escape.

[0004] On the other hand, the explosive-type release device uses a explosive energy of explosive to penetrate a needle member into a perforated surface provided in a compressed gas container. In this case, since the needle member is configured to be extremely lightweight, the needle member is automatically extracted by the release pressure of the compressed gas, so that it is not necessary to consider removing the needle member.

However, in the manual type release device, since a human operation is used to activate the release device, it is difficult to immediately operate the release device, and devices that require a so-called immediate response are required. Can not be used. Further, the conventional needle member has a problem that when the needle member is penetrated through the perforated surface of the compressed gas container, gas escape is insufficient and the gas release speed is low. Further, as described above, the device for manually removing the needle member once penetrated for better gas release can achieve an improved gas release speed, but has the additional feature of removing the needle member. Since a process is required, there is a problem that instant response is poor.

The explosive-type release device utilizes explosive energy of explosives, so that it has excellent immediate response and does not need to consider removing the needle member as described above. However, explosive-type release devices need to adjust the conditions for explosive explosion, such as adjusting the type, quality, quantity, etc. of explosive, and sealing the explosion chamber,
Further, there is a problem that handling is troublesome and the manufacturing cost of the apparatus is high, such as safety management of the explosive itself.

When the large-diameter portion 11 of the moving member 10 is located at the lowermost surface of the large-diameter hollow portion 21, the tip needle portion 15 a of the release needle 15 penetrates the drilling surface 210 by the length R. It is mounted in such a position.

The small-diameter hollow portion 2 of the moving member case 20
2 is provided with a gas release hole 23 extending in the circumferential direction and reaching the outer peripheral surface. Further, a screw portion 24 is formed on the upper outer surface of the movable member case 20. As shown in FIG. 1, a fixed member 30 is attached to the upper part of the movable member case 20.

Next, the fixing member 30 will be described with reference to FIG. The fixing member 30 has a substantially cylindrical outer shape, a large-diameter hollow portion 31 is formed at a substantially central portion in cross section from the lower end surface to the upper portion, and a screw portion is formed on an inner peripheral surface of the large-diameter hollow portion 31. 34 is formed, and the screw portion 24 of the movable member case 20 is screwed to the screw portion 34. A small-diameter hollow portion 3 communicating with the large-diameter hollow portion 31 is provided above the fixing member 30.
2 is formed coaxially with the large diameter hollow portion 31, and the moving member 10 penetrates the small diameter hollow portion 32. On the upper surface of the large-diameter hollow portion 31, an intermediate hollow portion 33 having a smaller diameter than the large-diameter hollow portion 31 and a larger diameter than the small-diameter hollow portion 32 is formed.

A spring member (coil spring) 40 that matches the diameter of the spring member 40 is attached to the intermediate hollow portion 33 of the fixed member 30. The other end of the spring member 40 is connected to the moving member 1
0 is fixed to the upper surface side of the large diameter portion 11. Spring member 40
The length selected is such that the large-diameter portion 11 of the moving member 10 is compressed from its natural length even in a state where the large-diameter portion 11 of the moving member case 20 is at the lowermost surface of the large-diameter hollow portion 21. Therefore, as shown in FIG. 1, the moving member 10 before the compressed gas is released is held at a position where the release needle 15 does not reach the perforated surface 210 by engagement with the holding member 50 described later. More strongly compressed, that is, the moving member 10 is
10 is strongly urged in the direction penetrating through.

Next, the holding member 50 will be described with reference to FIG. The holding member 50 has a substantially square rod-like outer shape, and has a rotation center hole 51 at one end. On the other hand, a small-diameter portion 53 having a circular cross section is provided on the other end side. Also,
A spring end mounting hole 54 is provided at a position adjacent to the small-diameter portion 53 on the center side, and an engagement groove 55 for engaging with the small-diameter portion 12 of the moving member 10 is provided on a side surface at the center portion. Is provided.

In the holding member 50, the engagement groove 55 is
The shaft member 60 is rotatably penetrated through the rotation center hole 51 at a position where the shaft member 60 can be engaged with the small-diameter portion 12. Also,
The shaft member 60 is fixed to the upper surface of the fixed member 30. Therefore, the holding member 50 is rotatable with respect to the fixed member 30 around the shaft member 60 as the center of rotation.

In FIG. 1, a starting spring member (whisker spring) 70 is wound around the shaft member 60. One end of the activation spring member 70 is fixed to the upper surface of the fixing member 30,
The other end takes the position of the broken line position N in FIG. 1B in the natural state, but is attached to the spring end attachment hole 54 of the holding member 50 by applying a force in the clockwise direction. In this state,
In order to maintain the holding member 50 coupled to the activation spring member 70 at a position where the activation member 70 is engaged with the moving member 10 against the force of the activation spring member 70 returning to the natural state (dashed line position N), One end of the release wire 80 is wound around the small-diameter portion 53, and the other end of the release wire 80 is fixed to a wire connection portion 90 provided on the upper surface of the fixing member 30 in a pulled state.

For this reason, the holding member 50 to which the starting spring member 70 is coupled is moved by the restoring force of the starting spring member 70 at a position where the holding member 50 is engaged with the moving member 10.
Is released counterclockwise about the shaft member 60 so as to release the engagement with the shaft member 60.

The release wire 80 is blown by a predetermined electric signal, and is connected to a fixed lead 85 for transmitting the electric signal at a wire connection portion 90 to form an electric activation device. . The predetermined electric signal in the present embodiment is a predetermined amount of current, but the form of the electric signal is not limited to this.

The compressed gas release device 100 shown in FIGS. 1 and 2
The compressed gas container 200 is in a state before the compressed gas is released. In this state, when a compressed gas release signal is generated, a predetermined amount of current is transmitted from the release signal transmitter (not shown) to the release wire 80 via the fixed lead 85.

The release wire 80 is instantaneously blown when a predetermined amount of current flows. As a result, the holding member 50 urged counterclockwise around the shaft member 60 by the activation spring member 70 loses the tension of the release wire 80 opposing the urging force.
It instantaneously rotates counterclockwise around zero.

With the rotation of the holding member 50, the engagement groove 55 of the holding member 50 comes off from the small diameter portion 12 of the moving member 10. That is, the engagement between the holding member 50 and the moving member 10 is released. For this reason, the moving member 10 is
The large-diameter portion 11 of the moving member 10 instantaneously reaches the lowermost surface of the large-diameter hollow portion 21 of the moving member case 20 due to the restoring force of the spring member 40.

Since the release needle 15 is formed in an arc-shaped cross section over the length L longer than the length R from the distal needle portion 15a, the release needle 15 does not have to be pulled out after the release needle 15 has penetrated the perforated surface 210. 3 (b), gas escape is performed smoothly in the direction of the arrow. The gas released from the perforated surface 210 passes through the gas release hole 23 and is instantaneously released.

As described above, according to the present invention, the moving member 1
Since the propulsion activation mechanisms 40 to 80 that move the release needle 15 so that the release needle 15 penetrates the perforated surface 210 are configured to be activated by an electric signal, the instant response is excellent. In addition, since the release needle 15 is formed in an arc-shaped cross section 15b over a length L longer than a length R at which the distal needle portion 15a penetrates the perforated surface 210, the release needle 1
Good outgassing can be realized without the step of extracting 5.

Further, according to the present invention, the moving member 10 having the release needle 15 is biased by the spring member 40 in advance, and the engagement by the holding member 50 opposing the biasing force is performed by a predetermined electric force. Since the release wire is released by blowing the release wire by a signal, the immediate response is further improved.

The cross-sectional shape of the release needle 15 desirably has sufficient mechanical strength as well as sufficient gas escape only by penetrating the perforated surface 210. Release needle 15 is excellent in both outgassing and mechanical strength. The shape of the release needle 15 is
In addition, it can be determined from ease of manufacturing, manufacturing cost, and the like.

The compressed gas release device according to the present invention is used for an observation buoy or the like used at sea. The observation buoy is
In addition to the compressed gas release device and the compressed gas container, a gas bag that is inflated by the released gas is provided. When the observation buoy reaches the sea surface or into the sea surface, a compressed gas release signal is generated, and the released gas reaches the inside of a gas bag (not shown).
