Description

Technical Field

[0001] The present invention relates to the technical field of compressed air energy storage, and in particular to a sealing and shock absorbing device and an air intake pipe assembly. Background Art

[0002] Compressed air energy storage (CAES) is a new energy storage technology that uses compressed air to generate energy during low-power periods and then uses it to generate electricity during peak periods, achieving the goal of storing energy. The use of newly excavated hard rock caverns as compressed air energy storage facilities is a growing trend. The compressed air pressure within these reservoirs can typically reach 10 MPa, and their sealing is crucial to their success.

[0003] Underground gas storages are generally sealed with plugs, and the air intake pipe needs to pass through the plug to enter the gas storage to deliver compressed air into the gas storage. Currently, the air intake pipe is usually buried directly in the concrete of the plug, which has the following disadvantages: First, the vibration of the air intake pipe may cause the pipe wall and the concrete of the plug to detach, resulting in gaps and forming leakage channels; second, the air intake pipe cannot be replaced after aging and damage due to long-term operation.

[0004] Therefore, how to effectively solve the vibration problem of the air intake duct and facilitate the replacement of the air intake duct is a problem that needs to be solved urgently. Summary of the Invention

[0005] The purpose of the present invention is to provide a sealing shock-absorbing device and an intake pipe assembly to solve the problems existing in the above-mentioned prior art, which can achieve effective shock absorption of the intake pipe, avoid the problem of separation between the intake pipe wall and the concrete of the gas storage plug in the prior art, resulting in a leakage channel, and facilitate the replacement of the intake pipe.

[0006] To achieve the above object, the present invention provides the following solutions:

[0007] The present invention provides a sealing and shock absorbing device, comprising:

[0008] A shock-absorbing sleeve, which can be buried in the gas storage plug and in which the air intake pipe can be installed;

[0009] Sealing connector, when the shock-absorbing sleeve is buried in the gas storage plug, the end of the shock-absorbing sleeve close to the gas storage can be sealed and connected to the air inlet pipe through the sealing connector.

[0010] Preferably, the shock-absorbing sleeve comprises a sleeve body, and the inner wall of the sleeve body is provided with a shock-absorbing layer.

[0011] Preferably, the shock-absorbing layer is a rubber plate.

[0014] Preferably, a sealing rubber is installed in the sleeve, and the end of the shock-absorbing sleeve close to the gas storage reservoir extends into the sealing rubber.

[0015] Preferably, a groove is provided at one end of the sealing rubber close to the shock-absorbing sleeve, and one end of the shock-absorbing sleeve close to the gas storage reservoir extends into the groove; wherein, the depth of the groove is less than the length of the shock-absorbing sleeve extending into the sealing rubber, and the thickness of the groove is less than the wall thickness of the shock-absorbing sleeve.

[0016] Preferably, the sealing rubber is detachably installed in the sleeve.

[0017] Preferably, an air hole is provided at one end of the sealing rubber close to the shock-absorbing sleeve, and the air hole can allow compressed air to enter to expand the sealing rubber.

[0018] The present invention also provides an air intake pipe assembly, comprising an air intake pipe and the sealing and shock absorbing device as described above.

In addition, the air intake pipe is not directly buried in the concrete of the gas storage plug, which facilitates replacement.

[0021] At the same time, the present invention provides a sealing connector. When the shock-absorbing sleeve is buried in the gas storage plug, the end of the shock-absorbing sleeve close to the gas storage can be sealed and connected to the air inlet pipe through the sealing connector to prevent air leakage.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide a sealing shock-absorbing device and an intake pipe assembly to solve the problems existing in the above-mentioned prior art, which can achieve effective shock absorption of the intake pipe, avoid the problem of separation between the intake pipe wall and the concrete of the gas storage plug in the prior art, resulting in a leakage channel, and facilitate the replacement of the intake pipe.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] like Figure 1-Figure 3 As shown, this embodiment provides a sealing shock-absorbing device, which mainly includes: a shock-absorbing sleeve and a sealing connector, wherein the shock-absorbing sleeve can be buried in the gas storage plug 2, and the air intake pipe 4 can be installed in the shock-absorbing sleeve; when the shock-absorbing sleeve is buried in the gas storage plug 2, the end of the shock-absorbing sleeve close to the gas storage 1 can be sealed and connected to the air intake pipe 4 through the sealing connector.

[0032] In this embodiment, when the air intake pipe 4 vibrates, it can be damped by the shock-absorbing sleeve, thereby avoiding the problem of the pipe wall of the air intake pipe 4 and the concrete of the gas storage plug 2 being detached, thereby causing a leakage channel; and the air intake pipe 4 is not directly buried in the concrete of the gas storage plug 2, which is convenient for replacement; at the same time, a sealing connector is provided in this embodiment, which can achieve a sealed connection between the shock-absorbing sleeve and the air intake pipe 4 to prevent leakage.

[0033] In this embodiment, the shock-absorbing sleeve includes a sleeve body 3, the inner wall of which is provided with a shock-absorbing layer. The shock-absorbing layer is located between the shock-absorbing sleeve and the air intake pipe 4, reducing vibration of the air intake pipe 4 and preventing collision between the air intake pipe 4 and the shock-absorbing sleeve. The shock-absorbing layer is preferably a rubber sheet 12, or other flexible materials can be selected according to specific working requirements.

[0034] In this embodiment, the sealing connector mainly includes a sleeve 5, which can be sealingly installed on one end of the intake pipe 4 extending into the gas storage reservoir 1, and is detachably connected to the shock-absorbing sleeve; wherein, the diameter of the sleeve 5 is larger than the diameter of the shock-absorbing sleeve, and the material of the sleeve 5 is the same as that of the intake pipe 4, and can be firmly welded or bonded to the intake pipe 4.

[0035] In this embodiment, a first flange 8 is mounted on the end of the shock-absorbing sleeve near the gas reservoir 1, and a second flange 7 is mounted on the end of the sleeve 5 near the gas reservoir plug 2. The first flange 8 and the second flange 7 are connected by bolts 9, achieving a detachable connection between the shock-absorbing sleeve and the sleeve 5, facilitating replacement of the intake pipe 4. Furthermore, a gap is left between the first flange 8 and the gas reservoir plug 2 to facilitate operation of the bolts 9.

[0036] In this embodiment, a sealing rubber 6 is installed in the sleeve 5, and the sealing rubber 6 is in close contact with the inner wall of the sleeve 5 and the outer wall of the intake pipe 4 to achieve sealing between the sleeve 5 and the intake pipe 4; and the end of the shock-absorbing sleeve close to the air storage reservoir 1 extends into the sealing rubber 6, which can seal the gap between the shock-absorbing sleeve and the intake pipe 4 to prevent leakage of compressed air in the air storage reservoir 1, and the provision of the sealing rubber 6 can also achieve shock absorption.

[0037] In this embodiment, the sealing rubber 6 is provided with a groove at one end near the shock-absorbing sleeve, and the end of the shock-absorbing sleeve near the gas storage reservoir 1 extends into the groove. The depth of the groove is less than the length of the shock-absorbing sleeve extending into the sealing rubber 6 (the length extending beyond the first flange 8), and the thickness of the groove is less than the wall thickness of the shock-absorbing sleeve. This allows the shock-absorbing sleeve to squeeze the sealing rubber 6 when inserted into the groove, thereby improving the sealing performance. It should be further explained that in this embodiment, the shock-absorbing sleeve extending into the sealing rubber 6 refers to the sleeve body 3 of the shock-absorbing sleeve extending into the sealing rubber 6.

[0038] In this embodiment, the sealing rubber 6 can be detachably installed in the sleeve 5 by means of snap connection, etc., so as to facilitate the replacement of the sealing rubber 6 after aging and ensure the sealing performance of the sealing rubber 6.

[0039] In this embodiment, an air hole 10 is provided at one end of the sealing rubber 6 close to the shock-absorbing sleeve, and the air hole 10 can allow compressed air to enter to expand the sealing rubber 6, so that the sealing rubber 6 can better contact closely with the pipe wall, thereby enhancing the sealing effect; wherein, a corresponding air hole 11 is provided on the first flange 8, and the air hole 11 is connected to the air hole 10, so that the compressed air in the gas storage reservoir 1 can enter the air hole 10.

[0040] In this embodiment, the shock absorbing sleeve and the air inlet pipe 4 can be made of steel or PVC.

[0041] This embodiment also provides an air intake pipe assembly, including an air intake pipe 4 and the sealing and shock absorbing device as described above.

[0042] The specific installation process of the sealing and shock absorbing device of this embodiment is as follows:

[0043] (1) The sealing rubber 6 is embedded in the sleeve 5, and the sleeve 5 can be tightly fitted to the peripheral wall of the intake pipe 4 by bonding or other methods.

[0044] (2) Insert the air intake pipe 4 into the shock-absorbing sleeve, and align the grooved portion of the sealing rubber 6 with the portion where the shock-absorbing sleeve extends.

[0045] (3) The extended portion of the shock-absorbing sleeve is squeezed into the sealing rubber 6 in the sleeve head 5 on the intake pipe 4, so that the wall of the shock-absorbing sleeve and the sealing rubber 6 fit tightly together, closing the gap between the intake pipe 4 and the shock-absorbing sleeve to achieve a sealing effect; in addition, the elastic function of the sealing rubber 6 can reduce the vibration of the intake pipe 4.

[0046] (4) A rubber sheet 12 is inserted between the shock-absorbing sleeve and the air intake pipe 4. Its functions are to reduce the vibration of the air intake pipe 4 and to prevent the air intake pipe 4 from colliding with the shock-absorbing sleeve.

[0047] (5) Use bolts 9 to connect the first flange 8 on the shock-absorbing sleeve and the second flange 7 on the sleeve head 5.

[0048] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all changes that fall within the meaning and range of equivalents of the claims be included in the present invention, and any reference signs in the claims should not be construed as limiting the claims to which they relate.
