Description

Technical Field

[0001] This utility model belongs to the field of pressure tank technology, specifically relating to a high-pressure double-layer pressure tank. Background Technology

[0002] A high-pressure double-walled pressure tank is a pressure vessel with a double-walled structure design. It is mainly used to store gases or liquids and can withstand high pressures through its structural characteristics.

[0003] Traditional high-pressure double-walled tanks have a relatively simple structure, often employing a simple interlocking design. The support structure between the inner and outer layers is mostly welded, making it impossible to adjust. This can easily lead to inadequate support in certain quadrants, resulting in insufficient structural stability. Furthermore, in actual use, if the inner layer expands, the welded support structure cannot provide adequate cushioning, easily causing the inner layer weld to tear and ultimately damaging the tank. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure double-layer pressure tank to solve the technical problems of poor support and protection effect and insufficient structural stability, thereby improving the support and protection effect and structural stability.

[0005] To solve the above-mentioned technical problems, this utility model provides a high-pressure double-layer pressure tank, including an outer shell, an inner shell inside the outer shell, and a plurality of support mechanisms equidistantly arranged around the inner shell and the outer shell.

[0006] The inner bottom of the outer shell and the adjacent support mechanism are both bonded with a heat insulation layer.

[0007] The support mechanism includes a fixed base, which is welded to the outer shell. An adjustment component is installed inside the fixed base. Several buffer components are installed at equal intervals from top to bottom on the inner side of the adjustment component. A clamp is installed between the inner side of the buffer component and the inner shell.

[0008] Furthermore, the outer periphery of the outer shell has several circular grooves corresponding to the support mechanism.

[0009] Furthermore, the insulation layer is made of polyurethane.

[0010] Furthermore, the adjusting assembly includes a threaded rod that is threadedly connected to a fixed seat. A base plate is rotatably connected to the inner end of the threaded rod. Limiting rods are symmetrically slidably connected to the top and bottom of the base plate. Both ends of the limiting rods are welded to the fixed seat.

[0011] Furthermore, the buffer assembly includes a sleeve welded to the inner side of the base plate, the sleeve being slidably connected to the fixed seat, a sliding rod being slidably connected inside the sleeve, and a damping buffer spring being fixedly connected between the inside of the sleeve and the sliding rod.

[0012] Furthermore, the clamping plate is made of semi-circular stainless steel and is welded to the slide rod on the outside. A protective pad is bonded to the inner side of the clamping plate where it contacts the inner shell.

[0013] Furthermore, the top of the inner shell is near the periphery and has several fixing rods threaded through the bottom, and the fixing rods are threadedly connected to the outer shell.

[0014] The beneficial effects of this utility model are:

[0015] 1. By using the fixed base, threaded rod, base plate and limit rod together, the buffer assembly and clamping plate can be moved inward and outward, thereby supporting the inner shell. With the insulation layer, the impact resistance of the outer shell can be improved while keeping it warm, effectively improving the structural stability.

[0016] 2. By using sleeves, slide bars, damping buffer springs and clamps in combination, the expansion and contraction of the inner shell can be adjusted automatically. Compared with traditional support structures, it can effectively prevent tearing of the weld seams of the inner shell and greatly improve the support and protection effect.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example:

[0025] like Figures 1 to 3 As shown, a high-pressure double-layer pressure tank includes an outer shell 1, an inner shell 2 inside the outer shell 1, and several support mechanisms 3 equidistantly arranged around the inner shell 2. Insulation layers 101 are bonded to the inner bottom of the outer shell 1 and between adjacent support mechanisms 3. Each support mechanism 3 includes a fixing seat 301, which is welded to the outer shell 1. An adjustment component 302 is installed inside the fixing seat 301. Several buffer components 303 are equidistantly arranged from top to bottom on the inner side of the adjustment component 302. A clamping plate 304 is installed between the inner side of the buffer component 303 and the inner shell 2.

[0026] like Figures 1 to 3As shown, the outer periphery of the outer shell 1 has several circular grooves 102 corresponding to the support mechanism 3. These grooves facilitate the rotation of the threaded rod 3021 using tools such as screwdrivers, improving ease of use. The insulation layer 101 is made of polyurethane, which has excellent thermal insulation properties and mechanical strength, effectively reducing heat loss and protecting the structure of the outer shell 1, thus improving its impact resistance. The adjustment component 302 includes a threaded rod 3021, which is threadedly connected to the fixed base 301. The inner end of the threaded rod 3021 is rotatably connected to... The base plate 3022 has symmetrical sliding connections of limit rods 3023 at its top and bottom. Both ends of the limit rods 3023 are welded to the fixed seat 301. Rotating the threaded rod 3021 allows the base plate 3022 to move inwards and outwards, thereby pushing the buffer assembly 303 and the clamping plate 304, causing the clamping plate 304 to fit against the inner shell 2, improving support stability. The limit rods 3023 limit the movement of the base plate 3022, preventing it from shifting and improving operational stability. The buffer assembly 3022... 03 includes a sleeve 3031, which is welded to the inner side of the base plate 3022. The sleeve 3031 is slidably connected to the fixed seat 301. A sliding rod 3032 is slidably connected inside the sleeve 3031. A damping buffer spring 3033 is fixedly connected between the inside of the sleeve 3031 and the sliding rod 3032. When the inner shell 2 expands, it will push the clamping plate 304 and the sliding rod 3032 outward. The damping buffer spring 3033 can provide a certain buffer space for the inner shell 2, preventing the weld from being forced to tear and improving the stability of use. The clamping plate 304 is made of semi-circular stainless steel and is welded to the slide rod 3032 on the outside. A protective pad is bonded to the inner side of the clamping plate 304 where it contacts the inner shell 2. The protective pad can prevent the inner shell 2 from directly contacting the clamping plate 304, thereby improving the protection effect on the outer surface of the inner shell 2. Several fixing rods 201 are threadedly connected to the top of the inner shell 2 near the outer periphery and through the bottom. The fixing rods 201 are threadedly connected to the outer shell 1. By rotating the fixing rods 201, the inner shell 2 and the outer shell 1 can be fixed together, improving the ease of use.

[0027] In summary, when supporting and adjusting a high-pressure double-layer pressure tank, firstly, use a screwdriver or similar tool to penetrate the circular groove 102 and rotate the threaded rod 3021, causing it to move the base plate 3022, buffer assembly 303, and clamping plate 304 outwards. This prevents the clamping plate 304 from obstructing the placement of the inner shell 2. Then, place the outer shell 1 around the inner shell 2 and rotate the fixing rod 201, causing it to spiral into the inner shell 1, thus fixing the inner shell 2 to the outer shell 1. Finally, use a screwdriver again to penetrate the circular groove 102 and reverse the threaded rod 3021, causing it to move the base plate 3022 outwards. The inner side moves, causing the base plate 3022 to move inward through the buffer assembly 303, driving the clamping plate 304 to move inward and close to the outer periphery of the inner shell 2, thus supporting the inner shell 2. Compared with the traditional welded support structure, this effectively improves the overall structural stability. When the inner shell 2 expands, the expanded local area will push the corresponding clamping plate 304 outward, which in turn pushes the slide rod 3032 to compress the damping buffer spring 3033. This allows the damping buffer spring 3033 to provide a certain buffer space for the inner shell 2, preventing the weld from being forced to tear. Compared with the traditional support mechanism 3, this greatly improves the support and protection effect.
