Description

[Detailed explanation of the invention] [Industrial application field] This invention is applicable to petrochemical factories, gas chemical factories, and other places where gas bodies (or fluids such as petroleum) are
The present invention relates to a tank device that is suitably used in applications that require the supply of water, and particularly to a tank device that is extremely suitably used when installed inside a ship or the like.

[Conventional technology and its problems]

Conventionally, a so-called floating roof type gas tank using a weight has been known as a tank device used for such purposes. This generally involves fitting a floating roof inside a hollow cylindrical tank shell made of metal, sealing the gap between the fittings to prevent gas leakage, and then releasing gas at a constant pressure using a weight. supply. However, such a floating roof type gas tank has the disadvantage that the design of the seal portion is troublesome and the sealing mechanism requires a large amount of cost.

In order to overcome these drawbacks, various proposals have been made, one of which is to construct a tank device using a flexible tank.

In such a device, a weight is placed on a flexible gas bag, and the weight applies a constant heavy pressure to the gas bag, thereby supplying gas at a constant pressure. The weight is usually supported at its four corners by wires or the like.

However, in the case of the above-mentioned wire type, it is fine as long as the installation surface of the tank device is always horizontal, but if the slope of the installation surface fluctuates, such as inside a ship, the horizontality between the installation surface and the top surface of the tank (top surface of the gas bag) cannot be maintained. This often resulted in loss of pressurization balance, and the ability of this type of device to constantly supply gas at a constant pressure was impaired.

The present invention was newly devised in view of such problems, and its purpose is not only to supply gas at a constant pressure at all times, but also to provide a gas supply system that can be used when the slope of the installation surface fluctuates, such as inside a ship. The object of the present invention is to provide a tank device that can fully fulfill this function even in various cases.

[Means for solving problems]

Therefore, the object of the present invention is to provide a flexible gas bag, a base on which the gas bag is placed, an arbitrary number of frames having opposing surfaces that stand up across the base, and a flexible gas bag. a required number of pairs of rack teeth provided on opposing surfaces of the gas bag, a weight placed on the gas bag, and a weight that is pivotally supported by the weight and meshes with the rack teeth to allow the weight to move up and down within the frame. It consists of a required number of pairs of pinions, a gear mechanism that is attached to the weight and interlocks with the paired pinions, and the gear mechanism rotates in conjunction with one side of the plurality of pairs of pinions, and a pair of connecting rods, large and small. A gear section formed by mutually meshing two sets of large gears of two stages of spur gears, and a chain that meshes with one side of the small gear of the gear section and transmits the rotation of each of the connecting rods to the gear section. This is achieved by a tank device.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

In FIGS. 1 and 2, a gas bag 1 made of a sheet of flexible and airtight material such as rubber-coated cloth is placed on a base 2 having a size that matches the bottom area of the bag. has been done. Reference numeral 3 denotes a frame, which is provided so that the base 2 is sandwiched between its legs 4. In this embodiment, two frames 3 are installed, but this number can be determined arbitrarily depending on the size of the gas bag 1, etc. The leg portions 4 of the frame 3 stand up with the base 2 in between, and rack teeth 5 are provided in pairs on each of their opposing surfaces. In the illustrated example, a pair of rack teeth 5 are installed on each frame 3, and if more frames are added, the number of rack teeth can be added as well, but they must always correspond to the number of frames. isn't it. A weight 6 is placed on the gas bag 1 and applies a certain pressure to it. In this embodiment, the structure is shaped like a lattice, but it goes without saying that it can take any other shape as long as it can function as a weight. On both sides of the weight 6,
A pinion 7 is pivotally supported at a position where it meshes with the rack teeth 5 of the frame 3. The pinions 7 are provided with the same number of pairs as the rack teeth, and by meshing with the rack teeth and moving up and down, the weight 6 can be moved up and down within the frame 3. Also, the weight 6 has a gear mechanism 8.
has been installed. As seen in FIG. 3, the gear mechanism 8 includes a pair of connecting rods 9 that are pivotally supported on each side of the weight 6 and rotate the pinion in conjunction with each other.
and the gear part 10, and the rotation of the connecting rod 9 is controlled by the gear part 10.
It has a chain 11 that transmits power to. Each connecting rod forms the axis of rotation for all pinions on each side,
Each chain 11 has a gear 12 fixed to a connecting rod 9.
It's meshing with each other. As shown in FIG.
are meshed with their respective chains 11, and the two large gears 14 are meshed with each other. Further, a gas inlet 15 and a gas outlet 16 are attached to the gas bag 1 at appropriate locations.

[Effect]

Next, the operation of the tank device of the present invention will be described. An empty gas bag 1 is filled with gas through the gas inlet 15 and stored therein, and the gas outlet is opened as necessary to allow the gas to flow out. At this time, the gas bag 1 is pressurized by the weight 6, so that gas can always be supplied at a constant pressure. On both sides of the weight 6, there are lock teeth 5 of the frame 3.
A pinion 7 that meshes with the frame 3 is pivotally supported, and the rotation of each of the pinions 7 is transmitted to each other by a gear mechanism 8 so that they all rotate equally, so that the vertical movement of the weight 6 along the frame 3 is always based on the It is carried out parallel to the table. That is, if the pinion on one side of the weight 6 tries to descend first, its rotation will rotate the connecting rod 9 that is interlocked with it, and this connecting rod 9 will rotate.
Rotate the pinion attached to. Further, the rotation of the connecting rod 9 is transmitted to one gear of the gear section via the chain 11 by the rotation of the gear 12 on the connecting rod 9. That is, the chain 11 rotates one small gear 13 of the gear part 10, and simultaneously rotates the large gear 1.
4 rotates the other large gear 14 that meshes with it. Then the other small gear 1 rotates at the same time.
3 interlockingly rotates the pinions on the other side of the weight 6 via the other chain and connecting rod in the opposite order to the above, thereby lowering the weights on the side to which these pinions are attached equally. . Therefore, only one side does not descend first, and the weight 6 can stably ascend and descend even if the installation surface is somewhat inclined. Therefore, once the frame 3 is fixed, a constant supply of gas can be made possible even in environments such as inside a ship.

[Effect of idea]

As is clear from the above explanation, the tank device of the present invention uses a simple mechanism to always maintain horizontality between the tank installation surface and the tank top surface (gas bag top surface). Even when the pressure fluctuates, gas can always be supplied at a constant pressure, making it extremely practical.
