Description

Technical Field

[0001] This utility model relates to a liquid storage tank forming technology, and in particular to a modular large-diameter circular liquid storage tank. Background Technology

[0002] In the construction and mining industries, large amounts of water are often required for operations. In the past, tap water was used directly for these operations. However, in today's water-scarce world, this method of water use has resulted in water waste. Therefore, water tanks are now used to store used water, which is then further treated and recycled. In current technology, water tanks are often built with building materials to store water. However, these tanks are often disposable and cannot be reused, resulting in waste.

[0003] In addition, there is a growing number of ultra-large-scale fracturing operations in China, such as shale gas drilling, multi-stage horizontal wells, and cluster well groups, which require more than 10,000 cubic meters of fluid. This necessitates greater on-site fluid preparation capacity. Due to stricter environmental regulations, "no-landing of fluids entering the well" will become the norm in production. Large quantities of waste slurry and waste liquid generated during drilling, downhole operations, and oil and gas production also require large-capacity temporary storage facilities. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a modular large-diameter circular liquid storage tank that is reasonably designed, easy to assemble and disassemble, reusable and has a changeable capacity.

[0005] The technical solution of this utility model is:

[0006] A modular large-diameter circular liquid storage tank includes unit template frames and a geomembrane. The unit template frames include an inner lining plate and a support frame. The support frame has a grid structure, consisting of horizontal beams and vertical beams that are intersected and connected. The inner lining plate is connected to the inner surface of the support frame. The upper and lower parts of the support frame are respectively provided with hinge seats. The lower hinge seat is rotatably connected to one end of a lower rotating rod, and the other end of the lower rotating rod is connected to an anchor pipe. The upper hinge seat is rotatably connected to one end of an upper rotating rod, and the other end of the upper rotating rod is rotatably connected to the hinge seat provided on the lower rotating rod. Each horizontal beam has bolt holes at both ends. Adjacent unit template frames are connected together in sequence by connecting plates, connecting bolts, and bolt holes to form a circular tank. The geomembrane is provided on the bottom and sides of the circular tank.

[0007] Furthermore: each of the connecting plates is one or two. When there is one connecting plate, it is disposed on the upper end face of the horizontal beam. When there are two connecting plates, they are respectively disposed on the upper and lower end faces of the horizontal beam and clamped together.

[0008] Furthermore, both the horizontal beam and the vertical beam are solid rod-like structures or hollow tubular structures, and the tubular structures are square tubes.

[0009] Furthermore: the upper end of the support frame is provided with two lifting rings at intervals, the inner lining plate is supported by a steel plate, and the support frame is provided with at least two sets of upper rotating rods and lower rotating rods.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model forms a supporting sidewall by connecting multiple unit template frames and laying a geomembrane inside, forming a detachable and reusable pool body, reducing the cost of use.

[0012] 2. The adjacent unit template frames of this utility model are connected by connecting plates and connecting bolts, which makes disassembly and assembly convenient and efficient.

[0013] 3. Both the upper and lower rotating rods of this utility model adopt a rotating connection, which can be disassembled and assembled, making it convenient for transportation and storage.

[0014] 4. An anchoring pipe is provided on the lower rotating rod of this utility model. The anchor rod is inserted into the foundation through the anchoring pipe, which increases the support force of the unit template frame, thereby ensuring the connection stability of the entire pool body.

[0015] 5. This utility model has a reasonable design, simple structure, convenient assembly and disassembly, can be reused and its capacity can be changed, making it easy to promote and implement, and its economic benefits are obvious after promotion. Attached Figure Description

[0023] Example 1: See Figures 1-7 In the diagram, 1-lower rotating rod, 2-horizontal beam, 3-vertical beam, 4-inner lining plate, 5-lifting ring, 6-upper rotating rod, 7-hinged seat, 8-anchor pipe, 9-bolt hole, 10-connecting bolt, 11-connecting plate.

[0024] A modular large-diameter circular liquid storage tank includes a unit template frame and a geomembrane. The unit template frame includes an inner lining plate 4 and a support frame. The support frame has a grid structure, which is formed by horizontal beams 2 and vertical beams 3 intersecting and connecting. The inner lining plate 4 is connected to the inner surface of the support frame. The upper and lower parts of the support frame are respectively provided with hinge seats 7. The lower hinge seat 7 is rotatably connected to one end of the lower rotating rod 1, and the other end of the lower rotating rod 1 is connected to the anchor pipe 8. The upper hinge seat 7 is rotatably connected to one end of the upper rotating rod 6, and the other end of the upper rotating rod 6 is rotatably connected to the hinge seat 7 provided on the lower rotating rod 1. Bolt holes 9 are provided at both ends of each horizontal beam 2. Adjacent unit template frames are connected together in sequence by connecting plates 11, connecting bolts 10 and bolt holes 9 to form a circular tank. The bottom and sides of the circular tank are provided with geomembrane.

[0025] Preferred solution: When there are two connecting plates 11 at each location, they are respectively set on the upper and lower end faces of the horizontal beam 2 and clamped together.

[0026] Preferred options: Both the horizontal beam 2 and the vertical beam 3 are solid rod-like structures or hollow tubular structures. The tubular structures are square tubes, which can be either square or rectangular, depending on the actual situation. They are not listed one by one.

[0027] Preferred solution: Two lifting rings 5 ​​are spaced apart at the upper end of the support frame. They can be welded together or connected by threads, depending on the situation. The inner lining plate 4 is supported by a steel plate. At least two sets of upper rotating rods 6 and lower rotating rods 1 are provided on the support frame. There are three sets in the figure. The number is determined according to the size of the support frame and will not be listed one by one.

[0028] When using it, estimate the capacity of the pool and then determine the number of unit template frames. Adjacent unit template frames are connected together in sequence by connecting bolts 10 and connecting plates 11 to form a circular structure. A geomembrane is laid inside to form the pool. Anchor rods are inserted into the foundation through anchor pipes to increase the support force of the unit template frames, thereby ensuring the connection stability of the entire pool.

[0029] Example 2: This example is basically the same as Example 1, and the similarities will not be repeated. The difference is that there is only one connecting plate at each point, which is set on the upper end face of the horizontal beam to simplify the structure.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
