Description

Technical Field

[0001] This invention relates to the field of liquid storage tank technology, and more particularly to large-scale, rapid-assembly modular liquid storage tanks. Background Technology

[0002] The liquid storage tank adopts a vertical or horizontal single-layer or double-layer structure, and is filled with insulation material according to user requirements. The tank body is made of steel plate. The liquid inlet is used to inject liquid from the outside into the storage tank, and the liquid outlet is used to drain the liquid stored in the tank. The safety valve is a device used to control the flow of liquid in the storage tank to prevent excessive leakage. The gas outlet is used to discharge gas from inside the storage tank. The working principle of the liquid storage tank is as follows: when liquid is injected into the storage tank, the safety valve will automatically open, and liquid will flow into the storage tank. When the liquid reaches a certain level, the safety valve will automatically close to prevent excessive leakage. When liquid is needed, the liquid outlet can be opened, and liquid will flow out of the storage tank. When liquid flows out, the safety valve will automatically open to replenish the liquid.

[0003] When transporting liquid goods using storage tanks, the quantity of liquid goods to be transported is variable, while the storage capacity of commercially available storage tanks is fixed. If the quantity of liquid goods to be transported is less than the storage capacity of the storage tank, the liquid goods will slosh around within the tank during transport, posing a safety hazard. Furthermore, the liquid goods may suffer from oxidation, moisture absorption, and contamination. Existing technologies employ sealed containers for storage, such as nitrogen-balanced seals or vacuum seals. While these methods can address issues like oxidation, moisture absorption, and contamination, the nitrogen gas is still compressed and the liquid goods move within the vacuum during transport, making it impossible to completely prevent sloshing and safety hazards. Similarly, a sealed storage tank with an elastic inner liner compensation device (authorization announcement number CN105691970B) described in Chinese patent CN105691970B, while mentioning an "elastic inner liner," also only addresses oxidation, moisture absorption, and contamination. However, the liquid goods can still compress the "elastic inner liner" during transport, making it impossible to completely prevent sloshing and safety hazards.

[0004] Therefore, based on the premise that "the amount of liquid cargo to be transported is less than the storage capacity of the liquid storage tank, during transportation, the liquid cargo will sway back and forth in the liquid storage tank, causing safety hazards, and will also be damaged by oxidation, moisture, and pollution; the existing technology of using sealed containers for sealed storage cannot completely solve the above problems", a large-scale rapid assembly modular liquid storage tank is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a large, rapidly assembled modular liquid storage tank, which aims to solve the problem that when the amount of liquid cargo to be transported is less than the storage capacity of the liquid storage tank, the liquid cargo will shake back and forth in the storage tank during transportation, causing safety hazards, and may also be damaged by oxidation, moisture, and contamination. The existing technology of using sealed containers for sealed storage cannot completely solve the above problems.

[0006] Specifically, the system comprises a large, rapidly assembled modular liquid storage tank, including multiple unit storage tanks connected in a detachable assembly. Multiple unit storage tanks are used for unitized liquid storage, and the number of unit storage tanks can be adjusted according to the actual volume of liquid being transported, allowing for flexible liquid storage. Each unit storage tank includes a tank cylinder with a storage cavity inside. A space adjustment disc is installed at the end of each storage cavity for adjusting its size. Because the storage tank is composed of multiple detachable unit storage tanks, the number of unit storage tanks can be adjusted according to the actual volume of liquid being transported, allowing for flexible adjustment of the storage space. Furthermore, the space adjustment disc can be activated to further adjust the storage space within the storage cavity, achieving more refined adjustments to the storage space of each unit storage tank. This completely eliminates safety hazards caused by the swaying of liquid goods during transport and prevents oxidation, moisture absorption, and contamination of the liquid.

[0007] The technical solution of this application will be further described below: In one embodiment, the space adjustment disc includes an adjustment disc body and a hydraulic cylinder. The adjustment disc body is fixed to the end of the hydraulic cylinder, and the end of the hydraulic cylinder away from the adjustment disc body is fixed to the inner side of the end of the liquid storage cavity. A rubber sealing sleeve is provided at the edge of the adjustment disc body. The adjustment disc body is set to match the internal cylindrical space of the liquid storage cavity, so that the adjustment disc body can move back and forth in a sealed manner inside the liquid storage cavity.

[0008] In one embodiment, the unit liquid storage tank further includes a quick assembly head one and a quick assembly head two, which are respectively distributed at both ends of the unit liquid storage tank cylinder; a support base is installed at the bottom of the unit liquid storage tank cylinder; and multiple unit liquid storage tanks can be detachably assembled and connected through the assembly between the quick assembly head one and the quick assembly head two.

[0009] In a further embodiment, the first quick assembly head includes a first mounting ring with multiple mounting holes arranged in a circular array. The second quick assembly head includes a second mounting ring with multiple locking elements arranged in a circular array. The locking elements and mounting holes correspond one-to-one, and the locking elements are inserted into the mounting holes to lock the first and second mounting rings together, thus completing the assembly between the first and second quick assembly heads.

[0010] In the optimized embodiment, the locking component includes a bolt and a nut. The bolt is threaded and fixed onto the second mounting ring, and the nut is threaded and fitted onto the bolt. The quick assembly head one and quick assembly head two are assembled by the bolt passing through the first and second mounting rings, and are locked together by the nut.

[0011] In the optimized embodiment, the first quick assembly head further includes an assembly plate, and the mounting ring is integrally mounted on the outside of the assembly plate; the second quick assembly head further includes an assembly plate, and the mounting ring is integrally mounted on the outside of the assembly plate.

[0012] The first assembly plate is provided with a sealing groove, and the second assembly plate is provided with a corresponding sealing insertion ring. The sealing insertion ring is inserted into the sealing groove to complete the sealed assembly between the first quick assembly head and the second quick assembly head.

[0013] The sealing groove has multiple negative pressure suction holes, which are arranged in a ring array inside the sealing groove. During the process of the sealing ring passing through the sealing groove, negative pressure is applied to the negative pressure suction holes, thus completing the strong negative pressure connection between the sealing ring and the sealing groove.

[0014] After assembly plate one and assembly plate two are attached together, locking devices are inserted into the mounting holes to lock mounting ring one and mounting ring two together, thus completing the locking between quick assembly head one and quick assembly head two through the external mounting ring one and mounting ring two via the locking devices. At the same time, on this basis, the sealing insertion ring is inserted into the sealing groove to apply negative pressure to the negative pressure extraction hole one, completing the strong negative pressure connection between the sealing insertion ring and the sealing groove, and realizing the ultra-strong negative pressure sealing connection between quick assembly head one and quick assembly head two.

[0015] In a further embodiment, the first quick assembly head is equipped with a plurality of locking insertion tubes arranged in a circular array, and the second quick assembly head is equipped with a plurality of locking sleeves arranged in a circular array, with each locking sleeve corresponding to a locking insertion tube. A second locking insertion tube is installed on the first quick assembly head inside the first locking insertion tube, and a second locking sleeve is provided on the second quick assembly head. The first locking insertion tube is locked inside the first locking sleeve, and the second locking insertion tube is locked inside the second locking sleeve, thereby achieving strong locking of the first and second quick assembly heads.

[0016] In the optimized embodiment, locking sleeve one and locking sleeve two adopt the same structure, and locking insertion tube one and locking insertion tube two adopt the same structure; locking insertion tube one includes a locking insertion tube body, which is integrally fixed on quick assembly head one, and a negative pressure suction hole two is opened at its end, and an external thread is opened on the outer wall of the locking insertion tube body; locking sleeve one includes a threaded sleeve, which is rotatably assembled on a rotating base, and the rotating base is integrally fixed on quick assembly head two, and an inner fixing post is fixed on the rotating base, and an inner adsorption locking plate is fixed at the end of the inner fixing post away from the rotating base; the threaded sleeve is threadedly sleeved on the locking insertion tube body, and the inner adsorption locking plate is inserted into the interior of the locking insertion tube body, and a strong negative pressure connection is further achieved by using the negative pressure suction hole two to ensure that locking insertion tube one and locking sleeve one are threadedly limited together.

[0017] Locking tube one is threaded and locked inside locking sleeve one, and locking tube two is threaded and locked inside locking sleeve two. Then, negative pressure is used to make a strong negative pressure connection through negative pressure suction hole two, so as to achieve a super strong negative pressure connection between quick assembly head one and quick assembly head two.

[0018] Compared with existing technologies, the large-scale, rapid-assembly modular liquid storage tank of this invention can achieve the following: Because the liquid storage tank is composed of multiple detachable liquid storage tanks, the number of assembled unit liquid storage tanks can be adjusted according to the actual amount of liquid being transported, allowing for flexible adjustment of the liquid storage space. Furthermore, by activating the space adjustment panel, the liquid storage space of the liquid storage cavity can be further adjusted, allowing for more refined adjustment of the liquid storage space of each unit liquid storage tank. This completely solves the safety hazards caused by the back-and-forth movement of liquid goods during transportation, as well as the problems of oxidation, moisture absorption, and contamination of the liquid goods. After assembly plate one and assembly plate two are attached together, locking components are inserted into the mounting holes to lock mounting ring one and mounting ring two together, thus completing the locking between quick assembly head one and quick assembly head two through the external mounting ring one and mounting ring two via the locking components. At the same time, on this basis, the sealing insertion ring is inserted into the sealing groove to apply negative pressure to the negative pressure suction hole one, completing the strong negative pressure connection between the sealing insertion ring and the sealing groove, and realizing the ultra-strong negative pressure sealing connection between quick assembly head one and quick assembly head two. Locking tube one is threaded and locked inside locking sleeve one, and locking tube two is threaded and locked inside locking sleeve two. Then, negative pressure is used to make a strong negative pressure connection through negative pressure suction hole two, so as to achieve a super strong negative pressure connection between quick assembly head one and quick assembly head two.

[0021] The following description sets forth many specific details to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0023] In embodiments of the present invention, such as Figure 1-5 As shown in Figure 10: A large-scale, rapidly assembled modular liquid storage tank includes multiple unit liquid storage tanks 100, which are detachably assembled and connected; multiple unit liquid storage tanks 100 are used for unitized liquid storage, and the number of assembled unit liquid storage tanks 100 can be adjusted according to the actual amount of liquid goods transported, for flexible liquid storage; In conclusion, based on the above, it can be concluded that since the liquid storage tank is composed of multiple detachable liquid storage tanks 100, the number of assembled unit liquid storage tanks 100 can be adjusted according to the actual amount of liquid being transported, thus flexibly adjusting the liquid storage space for flexible liquid storage. The unit liquid storage tank 100 includes a unit liquid storage tank cylinder 300, and a liquid storage cavity 320 is opened inside the unit liquid storage tank cylinder 300. A space adjustment plate 310 is installed at the end of the liquid storage cavity 320, and the space adjustment plate 310 is used to adjust the liquid storage cavity 320. Furthermore, summarizing the above, it can be concluded that: based on further adjusting the number of unit liquid storage tanks 100, the space adjustment plate 310 is activated to further adjust the liquid storage space of the liquid storage cavity 320, thereby achieving a more refined adjustment of the liquid storage space of the unit liquid storage tank 100, and completely solving the safety hazards caused by the back-and-forth shaking of liquid goods during transportation, as well as the damage caused by oxidation, moisture, and contamination of liquid goods.

It can also be purchased directly on the market, or the parts can be purchased on the market to assemble it, etc. It is not what this invention is meant to protect, so it will not be described in detail here, nor is it shown in the accompanying drawings.

[0024] In summary, since the liquid storage tank is composed of multiple detachable liquid storage tanks 100, the number of assembled unit liquid storage tanks 100 can be adjusted according to the actual amount of liquid being transported, allowing for flexible adjustment of the liquid storage space. Furthermore, by activating the space adjustment panel 310, the liquid storage space of the liquid storage cavity 320 can be further adjusted, allowing for more refined adjustment of the liquid storage space of each unit liquid storage tank 100. This completely solves the safety hazards caused by the back-and-forth movement of liquid goods during transportation, as well as the problems of oxidation, moisture absorption, and contamination of the liquid goods.

[0025] In embodiments of the present invention, such as Figure 10 As shown: The space adjustment disc 310 includes an adjustment disc body and a hydraulic cylinder. The adjustment disc body is fixed to the end of the hydraulic cylinder, and the hydraulic cylinder is fixed to the inner side of the end of the liquid storage cavity 320 at the end away from the adjustment disc body. A rubber sealing sleeve is fitted around the edge of the regulating disc. The regulating disc is designed to match the internal cylindrical space of the liquid storage cavity 320, and the regulating disc moves back and forth in a sealed manner inside the liquid storage cavity 320.

[0026] It should be further explained that: in addition to being cylindrical, the internal space of the liquid storage cavity 320 can also be triangular prism, square prism, etc., and there is no limit to the specific number, as long as the adjusting disc can move back and forth in a sealed manner inside the liquid storage cavity 320; these are all existing technologies, and can be purchased directly on the market. There are also relevant descriptions in corresponding journal articles, and they are not what this invention is intended to protect, so they will not be elaborated on here.

[0027] In embodiments of the present invention, such as Figure 1-5 As shown: The unit liquid storage tank 100 also includes a quick assembly head 200 and a quick assembly head 400, which are respectively distributed at both ends of the unit liquid storage tank cylinder 300; a support base 500 is installed at the bottom of the unit liquid storage tank cylinder 300. The assembly between the quick assembly head 1 (200) and the quick assembly head 2 (400) enables detachable assembly and connection between multiple unit liquid storage tanks (100).

[0028] In embodiments of the present invention, such as Figure 3 , 4 As shown in Figures 6-9: The quick assembly head 200 includes a mounting ring 220, which has multiple mounting holes 210 arranged in a ring array on the mounting ring 220. The quick assembly head 2 400 includes a mounting ring 2 420, on which multiple locking elements 410 are provided, and the multiple locking elements 410 are distributed in a ring array on the mounting ring 2 420; Multiple locking components 410 and multiple mounting holes 210 are arranged in a one-to-one correspondence. The locking components 410 are inserted into the mounting holes 210 to lock the mounting ring 220 and the mounting ring 420 together, thereby completing the assembly between the quick assembly head 200 and the quick assembly head 400.

[0029] In embodiments of the present invention, such as Figure 3 , 4 As shown in Figures 6-9: The locking component 410 includes a bolt and a nut. The bolt is threaded and fixed on the mounting ring 420, and the nut is threaded and sleeved on the bolt. The quick assembly head 1 200 and quick assembly head 2 400 are assembled by bolts passing through mounting ring 1 220 and mounting ring 2 420, and then locked together with nuts for limiting.

[0030] It should be further explained that the locking component 410 can be a bolt or nut, or it can be locked by magnetic attraction through a magnetic body, or by a limiting clamp, etc. These are all existing technologies, and there is no limitation on its specific structure, as long as it can meet the assembly requirements between the quick assembly head 200 and the quick assembly head 400. At the same time, it can be purchased directly from the market, and there are relevant descriptions in relevant journal literature. It is not what this invention is intended to protect, and will not be elaborated on here.

[0031] In embodiments of the present invention, such as Figure 3 , 4As shown in Figures 6-9: The quick assembly head 200 also includes an assembly plate 240, and the mounting ring 220 is integrally mounted on the outside of the assembly plate 240; the quick assembly head 400 also includes an assembly plate 440, and the mounting ring 420 is integrally mounted on the outside of the assembly plate 440.

[0032] In embodiments of the present invention, such as Figure 3 , 4 As shown in Figures 6-9: The first assembly plate 240 is provided with a sealing groove 230, and the second assembly plate 440 is provided with a corresponding sealing insertion ring 430. The sealing insertion ring 430 is inserted into the sealing groove 230 to complete the sealed assembly between the first quick assembly head 200 and the second quick assembly head 400.

[0033] In embodiments of the present invention, such as Figure 8 and Figure 9 As shown: The sealing groove 230 has multiple negative pressure suction holes 270 inside. The multiple negative pressure suction holes 270 are distributed in a ring array inside the sealing groove 230. During the process of the sealing insertion ring 430 being inserted into the sealing groove 230, negative pressure is applied to the negative pressure suction holes 270 to complete the negative pressure strong connection between the sealing insertion ring 430 and the sealing groove 230.

[0034] In summary, after the assembly plate 1 240 and assembly plate 2 440 are attached together, the locking element 410 is inserted into the mounting hole 210 to lock the mounting ring 1 220 and mounting ring 2 420 together. This completes the locking of the quick assembly head 1 200 and quick assembly head 2 400 through the external mounting ring 1 220 and mounting ring 2 420 and the locking element 410. At the same time, the sealing insertion ring 430 is inserted into the sealing groove 230 to apply negative pressure to the negative pressure extraction hole 1 270, completing the strong negative pressure connection between the sealing insertion ring 430 and the sealing groove 230, and realizing the super strong negative pressure sealing connection between the quick assembly head 1 200 and quick assembly head 2 400.

[0035] It should be noted that the negative pressure method of the negative pressure extraction port 270 is existing technology. Its detailed structure can be found in existing literature and journals, and it can also be purchased directly on the market, or the components can be purchased on the market and assembled, etc. It is not what this invention is meant to protect, so it will not be described in detail here, nor is it shown in the accompanying drawings. For example, it can be achieved by using an air pump to connect and achieve negative pressure.

[0036] In embodiments of the present invention, such as Figure 3 , 4As shown in 6-9, 11 and 12: The quick assembly head 200 is equipped with a plurality of locking insertion tubes 250 arranged in a ring array, and the quick assembly head 400 is provided with a plurality of locking sleeves 450 arranged in a ring array, with the plurality of locking sleeves 450 corresponding one-to-one with the plurality of locking insertion tubes 250. A second locking tube 260 is added to the quick assembly head 200 inside the first locking tube 250, and a second locking sleeve 460 is provided on the second quick assembly head 400. Locking insertion tube 1 250 is locked inside locking sleeve 1 450, and locking insertion tube 2 260 is locked inside locking sleeve 2 460, thus achieving strong locking of quick assembly head 1 200 and quick assembly head 2 400.

[0037] In embodiments of the present invention, such as Figure 3 , 4 As shown in 6-9, 11 and 12: the locking sleeve 450 and the locking sleeve 460 adopt the same structure, and the locking insertion tube 250 and the locking insertion tube 260 adopt the same structure; The locking insertion tube 250 includes a locking insertion tube body 2501, which is integrally fixed on the quick assembly head 200. The locking insertion tube body 2501 has a negative pressure suction hole 2502 at its end and an external thread 2503 on its outer wall. Locking sleeve 450 includes threaded sleeve 502, which is rotatably mounted on rotating base 4501. Rotating base 4501 is integrally fixed on quick assembly head 400. An inner fixing post 4503 is fixed on rotating base 4501. An inner suction locking disc 4504 is fixed at the end of inner fixing post 4503 away from rotating base 4501. The threaded sleeve 502 is threaded onto the locking insertion tube body 2501. The inner suction locking disc 4504 is inserted into the inside of the locking insertion tube body 2501. The negative pressure suction hole 2502 is used to further connect the locking insertion tube 250 and the locking sleeve 450 by threading them together.

[0038] In summary, after the assembly plate 1 240 and the assembly plate 2 440 are attached together, the locking element 410 is inserted into the mounting hole 210 to lock the mounting ring 1 220 and the mounting ring 2 420 together. This completes the locking between the quick assembly head 1 200 and the quick assembly head 2 400 through the external mounting ring 1 220 and the mounting ring 2 420 via the locking element 410. At the same time, the locking insertion tube 1 250 is threaded into the locking sleeve 1 450, and the locking insertion tube 2 260 is threaded into the locking sleeve 2 460. Then, the negative pressure suction hole 2502 is used to make a strong negative pressure connection, realizing a super strong negative pressure connection between the quick assembly head 1 200 and the quick assembly head 2 400.

[0039] It should be noted that the negative pressure method of the negative pressure extraction port 250 is existing technology. Its detailed structure can be found in existing literature and journals, and it can also be purchased directly on the market, or the components can be purchased on the market and assembled, etc. It is not what this invention is meant to protect, so it will not be described in detail here, nor is it shown in the accompanying drawings. For example, it can be achieved by using an air pump to connect the components and achieve negative pressure.

[0040] When the volume of liquid cargo to be transported is less than the storage capacity of the storage tank, the liquid cargo may slosh around within the tank during transport, posing a safety hazard. Furthermore, it may be susceptible to oxidation, moisture absorption, and contamination. Existing technologies using sealed containers for storage cannot completely solve these problems. This invention, a large-scale, rapidly assembled modular liquid storage tank, can achieve the following: Since the liquid storage tank is composed of multiple detachable liquid storage tanks 100, the number of assembled unit liquid storage tanks 100 can be adjusted according to the actual amount of liquid being transported, allowing for flexible adjustment of the liquid storage space. Furthermore, the space adjustment panel 310 can be activated to further adjust the liquid storage space of the liquid storage cavity 320, enabling more refined adjustment of the liquid storage space of each unit liquid storage tank 100. This completely solves the safety hazards caused by the back-and-forth movement of liquid goods during transportation, as well as the problems of oxidation, moisture, and contamination of the liquid goods.
