Description

Technical Field

[0001] The invention relates to the technical field of gas storage chamber construction, and in particular to a supporting device suitable for radial deformation of a steel plate sealing layer. Background Art

[0002] At present, in the underground gas storage chamber of the energy storage project, it is necessary to install a circular large-section steel plate sealing layer in the gas storage chamber to prevent gas leakage in the gas storage chamber. However, since the steel plate itself is very thin and the circular cross-section of the gas storage chamber is large, after the steel plate sealing layer is installed, during the pressurization and depressurization process in the gas storage chamber, the steel plate is prone to deformation and collapse, and rotational displacement, resulting in safety hazards for personnel entering for maintenance during depressurization, and easily leading to stress concentration in the steel plate sealing layer, causing local damage to the steel plate sealing layer, affecting its service life. Summary of the invention

[0003] The main purpose of the present invention is to provide a supporting device suitable for radial deformation of a steel plate sealing layer to solve the above-mentioned problem.

[0004] To achieve the above-mentioned purpose, the present invention provides a supporting device suitable for radial deformation of a steel plate sealing layer, comprising:

[0005] bearing drum;

[0009] A plug, one end of which is sleeved in the socket, and the other end of which is fixedly connected to the steel plate sealing layer.

[0010] Furthermore, a fixing block is provided at one end of the plug close to the steel plate sealing layer, and the fixing block is fixedly connected to the steel plate sealing layer.

[0017] In order to achieve the above-mentioned purpose and effect, the technical means and structures adopted by the present invention are described in detail with reference to the accompanying drawings for the features and functions of the preferred embodiments of the present invention.

[0018] like Figure 1 As shown, the present invention provides a supporting device suitable for radial deformation of a steel plate sealing layer, comprising:

[0019] Bearing drum 1;

[0020] A plurality of support spokes 2, wherein the plurality of support spokes 2 are arranged on the side wall of the bearing drum 1, and the plurality of support spokes 2 are evenly distributed along the circumference of the bearing drum 1;

[0021] A support ring beam 3, which is arranged on the outside of the bearing drum 1, the support ring beam 3 is concentric with the bearing drum 1, and the support ring beam 3 is connected to the bearing drum 1 through the support spokes 2;

[0022] A plurality of jacks, the jacks are arranged on the support ring beam 3, and the plurality of jacks are evenly distributed along the circumference of the support ring beam 3;

[0023] The plug 4 has one end which is sleeved in the socket and slidably connected to the socket, and the other end which is fixedly connected to the steel plate sealing layer 5.

[0024] Specifically, the length of the plug 4 should be greater than the radial deformation distance of the steel plate sealing layer 5 to prevent the plug 4 from falling off from the insertion hole when the steel plate sealing layer 5 is deformed.

[0025] Specifically, the plug 4 is fixedly connected to the steel plate sealing layer 5 by bolts or welding.

[0026] Preferably, in general, 24 plugs 4 are provided, and the actual number can be adjusted according to the size of the circular cross-section of the steel plate sealing layer. The plug 4 is inserted into the socket by 15 cm and the outer diameter of the plug 4 is smaller than the inner diameter of the socket, so that the plug 4 will not be pulled out of the socket when the steel plate sealing layer 5 is radially deformed, and the plug 4 can move freely between the socket.

[0027] During actual use, when the steel plate sealing layer 5 is released from pressure, the steel plate sealing layer 5 will undergo radial inward shrinkage deformation. At this time, the supporting ring beam 3 will come into contact with the steel plate sealing layer 5, support the steel plate sealing layer 5, and prevent the steel plate sealing layer 5 from collapsing; when the steel plate sealing layer 5 is pressurized, the steel plate sealing layer 5 will undergo radial outward expansion deformation, and the steel plate sealing layer 5 will move away from the supporting ring beam 3. At this time, the plug 4 will also move away from the supporting ring beam 3, but the plug 4 will always be mounted in the socket, thereby limiting the rotational displacement of the steel plate sealing layer 5.

[0028] In this embodiment, a fixing block is provided at one end of the plug 4 close to the steel plate sealing layer 5 , and the fixing block is fixedly connected to the steel plate sealing layer 5 , thereby ensuring the fixing effect of the plug 4 and the steel plate sealing layer 5 .

[0029] In this embodiment, a rubber ring is provided in the socket, and the plug 4 is sleeved in the rubber ring, so that the position of the plug 4 is relatively restricted while the plug 4 can move in the socket.

[0030] In this embodiment, the socket and the plug 4 are filled with butter to ensure that the plug 4 can move freely in the socket.

[0031] In this embodiment, a support rod is provided at the bottom of the bearing drum 1, and the support rod is a telescopic structure, so that the bearing drum 1 is supported by the support rod, thereby facilitating the installation of the device.

[0032] Preferably, a plurality of lifting ears are evenly distributed on the top of the bearing drum 1 to facilitate lifting of the bearing drum 1 .

[0033] The above descriptions are only preferred embodiments of the present invention, not all embodiments. Anyone should be aware that any structural changes made under the inspiration of the present invention, and any technical solutions that are the same or similar to the present invention, belong to the protection scope of the present invention.
