Description

Technical Field

[0001] The utility model relates to the technical field of gas holders, in particular to a sunken ventilation air louvre gas holder. Background Art

[0002] The cylinder body of the gas holder is used for storing gas. Generally, a piston is arranged inside the cylinder body of the gas holder, which can move up and down inside the cylinder to adjust the gas pressure inside the gas holder.

[0003] In order to discharge the gas with a higher temperature inside the gas holder, generally, a raised ventilation air louvre is arranged on the top of the gas holder. An air outlet is formed between the ventilation air louvre and the top, so that the gas with a higher temperature inside can be discharged from the air outlet to achieve the purpose of internal ventilation and air exchange. Moreover, a rainproof structure is arranged in the ventilation air louvre to prevent rainwater from flowing into the room from the air outlet. This kind of air louvre can refer to the air louvre structure disclosed in Chinese Patent CN208884812U, a cross-shaped ventilation air louvre.

[0004] However, after the traditional raised ventilation air louvre is set, when there is wind, it is equivalent to erecting a huge windbreak wall on the top of the gas holder. The strong wind often has a great impact on the strength and stiffness of the top of the gas holder, and it is easy to cause large deformation of the top of the gas holder. Therefore, this application proposes a sunken ventilation air louvre gas holder to solve the above problems. Summary of the Utility Model

[0005] The utility model provides a sunken ventilation air louvre gas holder to solve the problems put forward in the above background art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A sunken ventilation air louvre gas holder includes a gas holder cylinder body and a gas holder piston arranged inside the gas holder cylinder body. The bottom side of the top of the gas holder cylinder body is fixedly connected with an inner cylinder and an outer cylinder. The inner cylinder is located inside the outer cylinder. The top and the top of the inner cylinder are both open. The top opening of the inner cylinder is communicated with the outside. The bottom of the outer cylinder is fixedly connected with a drain pipe. One end of the drain pipe extends out of the side wall of the gas holder cylinder body. A plurality of power-free wind caps are installed on the peripheral side walls of the outer cylinder. The plurality of power-free wind caps are located between the inner cylinder and the outer cylinder.

[0008] Preferably, a heat insulation board is arranged on the outer side wall of the outer cylinder.

[0009] Preferably, the bottom of the outer cylinder is arranged in a hemispherical shape.

[0010] Preferably, a plurality of annular walkways are arranged outside the gas holder cylinder body.

[0011] Preferably, an external inclined ladder is arranged outside the gas holder cylinder body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device forms a sunken gas louver by setting an outer cylinder, a non-powered wind cap, and an inner cylinder on the top and bottom of the gas holder. This avoids the wind-blocking effect of using a raised gas louver, greatly improves the stress condition of the traditional gas holder, and significantly extends the service life of the gas holder.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described in more detail below by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figures 1-5 In this embodiment of the utility model, a sunken ventilation louver gas holder includes a gas holder cylinder 1 and a gas holder piston disposed inside the gas holder cylinder 1. An inner cylinder 8 and an outer cylinder 6 are fixedly connected to the top and bottom sides of the gas holder cylinder 1. The inner cylinder 8 is located inside the outer cylinder 6. The top and bottom of the inner cylinder 8 are both open, and the top opening of the inner cylinder 8 communicates with the outside. The bottom of the outer cylinder 6 is hemispherical, and a drain pipe 4 is fixedly connected to the bottom of the outer cylinder 6. One end of the drain pipe 4 extends out of the side wall of the gas holder cylinder 1. Multiple non-powered air caps 7 are installed on the four sides of the outer cylinder 6. The multiple non-powered air caps 7 are located between the inner cylinder 8 and the outer cylinder 6. A heat insulation plate 5 is provided on the outer side wall of the outer cylinder 6. Under the action of temperature difference, the non-powered air caps 7 can automatically rotate to drive air flow. The heat insulation plate 5 can improve the temperature difference between the inside of the gas holder cylinder 1 and the outside temperature, which facilitates the ventilation effect of the non-powered air caps 7.

[0026] Specifically, the gas holder cylinder 1 is provided with an external inclined ladder 3 and multiple annular walkways 2 on its exterior, and multiple ventilation holes are also provided on the side wall of the gas holder cylinder 1.

[0027] The working principle of this utility model is as follows:

[0028] By utilizing the temperature difference between the air inside the gas holder cylinder 1 and the outside air to create negative pressure, the non-powered vent cap 7 can rotate automatically, causing the air inside the gas holder cylinder 1 to flow into the outside air through the non-powered vent cap 7, effectively ensuring the necessary ventilation inside the gas holder cylinder 1. When it rains, after rainwater enters the outer cylinder 6, the drain pipe 4 can drain the water, preventing it from entering the gas holder cylinder 1, thus creating a sunken ventilation and rainproof effect.
