Description

Technical Field

[0001] This application relates to the field of aquaculture, and more specifically, it relates to a fully prefabricated composite concrete modular water tank for aquaculture. Background Technology

[0002] With continuous breakthroughs and evolution in science and technology, coupled with dynamic changes in natural environmental conditions, the transformation and upgrading of socio-economic development needs, and the increasing pursuit of a high-quality life and health by humankind as living standards continue to improve, the aquaculture industry is undergoing profound changes. Correspondingly, various aquaculture equipment and facilities are also constantly being improved and upgraded. Many traditional aquaculture products are gradually being phased out and replaced by new products with higher technological content and better production efficiency. In terms of aquaculture facilities, a typical development path is evident: from the early, simple, and extensive open-air excavation of underground ponds, to the gradual evolution to high-standard, high-precision aquaculture ponds constructed using various new materials.

[0003] However, looking at the current state of the industry, even after the aforementioned technological upgrades, various traditional aquaculture pond structures still exhibit limitations to varying degrees in practical applications, failing to fully meet the comprehensive demands of the modern aquaculture market for efficiency, safety, environmental protection, and economy. Specifically, this manifests in the following aspects: (1) Open-air excavated aquaculture ponds (open-air earthen ponds): These ponds are highly dependent on natural environmental conditions and are significantly affected by regional climate, soil structure, and the surrounding ecological environment. Because the water body is in a relatively open state, water quality parameters (such as dissolved oxygen, temperature, pH value, ammonia nitrogen content, etc.) are easily affected by external disturbances and fluctuate, making it difficult to achieve long-term stable control. This limitation not only restricts the types of aquatic products suitable for cultivation but also greatly affects the quality stability and hygiene and safety level of aquaculture products, making it difficult to meet increasingly stringent market access standards and consumers' expectations for food safety.

[0004] (2) Stainless steel plate welded water tanks: The main raw material for this type of water tank is stainless steel plate containing alloying elements such as nickel and chromium. Its market price is greatly affected by fluctuations in international metal prices, resulting in a relatively high overall construction cost. At the same time, the construction process requires extremely strict operational skills and experience from the welders, and the quality of the weld directly determines the overall safety and service life of the water tank. In actual use, the welded joint area often becomes a weak point, prone to leakage or even corrosion due to stress concentration and localized corrosion. Especially in aquaculture water environments with high salt content or high chloride ion concentration, the weld area is more prone to electrochemical corrosion, leading to weld peeling and cracking. In severe cases, it may cause structural failure of the tank or even overall collapse, resulting in a large amount of repetitive maintenance and repair costs, significantly reducing the economic efficiency of the facility.

[0005] (3) Cast-in-place reinforced concrete aquaculture reservoirs: The structural design of this type of reservoir is relatively complex, requiring the erection of a large number of formworks during the construction phase. This is especially true for irregularly shaped reservoirs with many corners and high walls, where the fixing and reinforcement of the formwork system is particularly cumbersome, significantly increasing the construction difficulty and labor and material costs. In addition, the vibration operation during concrete pouring is highly dependent on the experience of the operators, and human factors have a significant impact, which can easily lead to localized incomplete compaction, resulting in quality defects such as honeycomb and pitting on the surface of the reservoir, weakening the overall compactness and impermeability of the concrete structure. At the same time, the large number of tie rods set up to fix the formwork system are difficult to remove later, and the tie rods are prone to corrosion in humid environments. Rust water seeps into the water body and causes continuous pollution to the water quality in the reservoir, further aggravating the burden on water purification. The above problems together result in high comprehensive costs for this type of reservoir in terms of construction investment, daily maintenance and water quality management, which is not conducive to the promotion of large-scale and intensive aquaculture models.

[0006] It is evident that the current mainstream aquaculture pond structures generally suffer from a series of systemic shortcomings, such as cumbersome manufacturing processes, high redundancy in structural design, large investment in construction and maintenance, and difficulty in maintaining excellent aquaculture water quality in the long term. Summary of the Invention

[0007] This application provides a fully prefabricated composite concrete modular aquaculture tank. The overall structure of the tank is assembled from prefabricated wall panels. These prefabricated wall panels are then connected by tie clamps and sealing adhesives, followed by secondary grouting for integral molding. This simplifies the manufacturing process, saves on-site assembly time, and facilitates cleaning, maintenance, and upkeep, thus better maintaining the quality of the aquaculture water. Furthermore, the tank structure includes a frame structure, which not only provides support during construction but also facilitates daily cleaning of the tank's corners.

[0008] This application provides a fully prefabricated composite concrete modular aquaculture tank, which adopts the following technical solution: A fully prefabricated composite concrete modular aquaculture tank includes a bottom slab and a water storage and aquaculture tank, a water purification tank, and an enclosing isolation and protection structure disposed on the bottom slab. The water purification tank is located on the outer periphery of the water storage and aquaculture tank, and the enclosing isolation and protection structure is located on the outer periphery of the water purification tank. The water storage and aquaculture tank, the water purification tank, and the enclosing isolation and protection structure are all assembled from structures including precast wall panels, tie rods, and sealing adhesives. The bottom slab is provided with a bottom groove for grouting and fixing of the precast wall panels. The precast wall panels are formed by pouring grout into the tie rods and in the bottom groove. The prefabricated wall panels of the water storage aquaculture pond include straight-shaped wall panels and L-shaped wall panels, and the water storage aquaculture pond is formed by enclosing and assembling the end walls of the straight-shaped wall panels and L-shaped wall panels to form the inner wall panel of the water pond; the prefabricated wall panels of the water purification pond and the enclosing isolation protection body include straight-shaped wall panels, L-shaped wall panels and π-shaped special-shaped wall panels, and the water purification pond is formed by enclosing the opposite two end walls of the π-shaped special-shaped wall panels and the end walls of the straight-shaped wall panels and L-shaped wall panels to form a middle partition baffle; the enclosing isolation protection body is formed by enclosing the opposite two end walls of the π-shaped special-shaped wall panels and the end walls of the straight-shaped wall panels and L-shaped wall panels to form an outer wall panel; two adjacent end walls of the π-shaped special-shaped wall panels in the water purification pond and the enclosing isolation protection body are both arranged facing the water storage aquaculture pond and connected with adjacent prefabricated wall panels; reserved water passing grooves are provided on two adjacent plate bodies of the π-shaped special-shaped wall panels; A liftable shaping frame is arranged on the bottom plate at the corner of the prefabricated wall panel, and the shape of the shaping frame extends along the corner shape of the prefabricated wall panel in the horizontal direction; a receiving groove is arranged on the outer side wall of the shaping frame; a shaping block or a cleaning brush is detachably connected to the shaping frame, and the shaping block or the cleaning brush is connected with the shaping frame through a detachable member; the shaping block or the cleaning brush is further slidably mounted on the shaping frame along the horizontal direction through a sliding member, and the shaping block or the cleaning brush is close to the prefabricated wall panel under the action of the sliding member.

[0009] By adopting the above technical solution, for the water quality structure of the present application, the water storage aquaculture pond can meet basic aquaculture requirements; the water purification pond can provide a space for water purification work, and can be used for installing the external circulating purification water system of the aquaculture pond; the enclosing isolation protection body plays a supporting and protective role on the outer peripheral side of the water pond, serves as the outer maintenance wall for the circulating purified water of the aquaculture pond, and also serves as a supporting member for the overall structure of the water pond, so as to ensure the stability of the water pond structure.

[0010] Furthermore, the aquaculture tank, water purification tank, and enclosed isolation and protection structure of this application are all constructed from precast concrete wall panels, which are then connected to the base slab as a structural whole through secondary grouting. On one hand, using precast concrete wall panels can more effectively reduce the time required for hoisting and installation, and significantly save costs. Especially in terms of corrosion and rust prevention, precast concrete wall panels are far superior to metal structures. Metal has a certain degree of flexibility and will deform to some extent under the pressure of the panels themselves and water. Over time, excessive deformation may cause the tank body to deform, the welds to crack, leading to leakage or even collapse. On the other hand, this application is assembled, making the connection between the various parts convenient and significantly improving the on-site assembly speed. Simultaneously, the cooperation of the precast concrete wall panels helps improve the density, impermeability, and environmental performance of the tank compared to cast-in-place structures.

[0011] In addition, regarding the shape of the prefabricated wall panels, the "I"-shaped and "L"-shaped wall panels have simple structures and meet the basic structural requirements of aquaculture tanks, water purification tanks, and enclosed isolation and protection structures. "Qi"-shaped irregular wall panels have been added to the prefabricated wall panels of the water purification tanks and enclosed isolation and protection structures. On the one hand, the individual "I"-shaped sections of the "Qi"-shaped wall panels can be easily connected; on the other hand, the two parallel "I"-shaped sections of the "Qi"-shaped wall panels can form lateral supports between adjacent external wall panels, central blocking panels, and inner wall panels of the tank, improving both construction efficiency and the overall stability of the tank structure. A pre-reserved water passage channel meets the water flow requirements of the water purification tank, facilitating water purification treatment.

[0012] However, due to the special structure of the π-shaped special-shaped wall panel, including the four corners of the water purification tank, there are many corner structures in the water tank structure, and the side walls of these corner structures are very prone to adhering sundries, which will affect the water purification effect over time; therefore, daily cleaning of positions such as the corners of the water tank is also very important, so the present application is further provided with a shaping frame structure. For the mounting frame structure of the present application, since the shape of the shaping frame extends along the corner shape of the prefabricated wall panel in the horizontal direction, the position of the shaping block can be adjusted during the construction of the water tank in cooperation with the shaping block structure, so as to form support for the prefabricated wall panel. In particular, for the two parallel side panels in the π-shaped special-shaped wall panel, the shaping frames are arranged on both sides of each side panel, so that the prefabricated wall panel can be clamped by the fitting effect of the shaping blocks, and then supported, so as to improve the stability during the construction process. In addition, due to the arrangement of the detachable connection structure, the shaping block can be removed after the construction is completed, and a cleaning brush can be installed. During the daily maintenance process, the sliding member is used to adjust the position of the cleaning brush to make it fit the side wall of the prefabricated wall panel, and by adjusting the shaping frame to ascend, the cleaning brush can be used to perform basic daily cleaning on the side wall of the prefabricated wall panel. Moreover, due to the arrangement of the detachable structure, the cleaning brush can also be replaced after a period of time to ensure the cleaning effect of the cleaning brush.

[0013] Further, there are gaps between both the bottom wall and the top wall of the accommodating groove and the opposite prefabricated wall panel, wherein the gap at the top wall of the accommodating groove is larger than the gap at the bottom wall; the detachable member includes a transposition shaft and a friction plate, the bottom wall of the accommodating groove close to the groove opening forms a sliding support plate, the friction plate is rotatably connected to the top wall of the shaping frame through the transposition shaft, the friction plate and the shaping frame are positioned by friction, and both the top wall of the shaping frame and the shaping block are fitted with the bottom wall of the friction plate, or both the top wall of the shaping frame and the cleaning brush are fitted with the bottom wall of the friction plate.

[0014] By adopting the above technical solution, the friction plate is rotated, and when the friction plate is located on the top walls of the shaping frame and the shaping block at the same time, or on the top walls of the shaping frame and the cleaning brush at the same time, it can cooperate with the sliding support plate to limit the shaping block or the cleaning brush; such a fixing structure has a simple structure and is convenient to operate.

[0015] Furthermore, the sliding component includes a clamping stud, a pushing block, and a force-receiving inclined block. The force-receiving inclined block is slidably disposed in the receiving groove, with its inclined surface facing inwards towards the receiving groove and its upper surface inclined towards the groove opening. The side wall of the force-receiving inclined block away from the receiving groove is attached to and magnetically connected to the side wall of the shaping block or cleaning brush. The clamping stud is threadedly connected to the top wall of the shaping frame and extends into the receiving groove. The pushing block is disposed at the bottom end of the clamping stud, and its bottom wall is a spherical surface that abuts against the inclined surface of the force-receiving inclined block. Further still, a guide block is provided on the bottom wall of the force-receiving inclined block, and the receiving groove is provided with a guide groove. The guide block is slidably disposed on the groove wall along the diagonal direction of the shaping frame.

[0016] By adopting the above technical solution, the threaded feed of the clamping stud can drive the propulsion block to move. Then, by utilizing the inclined surface action of the propulsion block on the force-bearing inclined block, the force-bearing inclined block can be pushed towards the precast wall panel, thereby driving the mounting block or cleaning brush closer to the precast wall panel. Furthermore, since the shaping frame is mainly L-shaped, this application sets the force-bearing inclined block to move along the diagonal of the shaping frame. This allows the shaping block or cleaning brush to move towards the precast wall panel simultaneously, making operation more convenient. Moreover, the contact surface between the propulsion block and the inclined surface of the force-bearing inclined block is spherical. Therefore, when the propulsion block rises, falls, and rotates with the clamping stud, it can smoothly and stably slide relative to the force-bearing inclined block. Thus, regardless of the propulsion block's installation position, it will not affect the force applied by the propulsion block to the force-bearing inclined block. Furthermore, when the propulsion block is not on the diagonal of the shaping frame, the rotation of the propulsion block can have a component force on the force-bearing inclined block in the diagonal direction of the shaping frame, which is more conducive to pushing the force-bearing inclined block. Meanwhile, this application uses magnetic connection between the force-bearing inclined block, the shaping block, and the side of the cleaning brush to improve the installation stability of the shaping block and the cleaning brush on the shaping frame.

[0017] Furthermore, a support rod is provided on the side wall of the shaping frame, and the support rod and the shaping frame are slidably connected in the vertical direction. The support rod and the shaping frame are positioned by friction, and the bottom wall of the support rod is fixedly connected to the base plate.

[0018] By adopting the above technical solution, friction positioning is directly used, which not only simplifies the structure but also makes it easier to operate when raising and lowering the shaping frame.

[0019] Furthermore, the sidewalls of the shaping frame are coated with an anti-fouling layer.

[0020] By adopting the above technical solutions, the anti-fouling layer can reduce the adhesion of debris to the mounting frame structure.

[0021] Furthermore, the shaping block has several shaping arc strips on its sidewall facing the precast wall panel. The axial direction of the shaping arc strips is vertical and the arc surface is used to abut against the precast wall panel.

[0022] By adopting the above technical solution, since the supporting force of the shaping block on the precast wall panel is mainly in the horizontal direction, the shaping arc strip will not affect the supporting effect of the shaping block on the precast wall panel. However, during the construction process, the precast wall panel may move in the vertical direction. Therefore, setting the shaping arc strip can reduce the contact area between the shaping block and the precast wall panel, thereby reducing the friction between the shaping block and the precast wall panel and facilitating the movement of the precast wall panel.

[0023] Furthermore, the bottom end of the prefabricated wall panel is inserted into the bottom groove and fixed by pouring grout. The bottom groove on the bottom plate includes an inner wall panel groove for assembling the prefabricated wall panel of the water storage aquaculture pond, a middle blocking plate groove for assembling the water purification pond, and an outer wall panel groove for assembling the prefabricated wall panel of the enclosing isolation and protection body.

[0024] By adopting the above technical solutions, the bottom trench provides an installation foundation for the precast wall panels. After secondary pouring, a stable connection is achieved between the precast wall panels and the bottom slab. Moreover, different bottom trench structures correspond to different precast wall panel structures, which can quickly confirm the installation position of the precast wall panels and improve construction efficiency.

[0025] Furthermore, the end walls of the "I"-shaped wall panel, the end walls of the "L"-shaped wall panel, and the opposite end walls of the "Q"-shaped irregular wall panel are all connected to other structures through tie clamps, and the two adjacent end walls of the "Q"-shaped irregular wall panel are connected to other structures through sealing adhesives.

[0026] Furthermore, the tie clamping member includes tie clamping plates and tie bolt nuts. There are two tie clamping plates, and the connecting end of the precast wall panel is located between the two tie clamping plates. The tie bolt nuts are fixed between the two tie clamping plates.

[0027] By adopting the above technical solution, the two tie plates form a basic fixed connection under the fixing action of the tie bolts and nuts. Then, grout is poured into the space between the two tie plates for a second time. At the same time, the grout flows into the corresponding bottom groove, which can stably connect the precast wall panel and the bottom plate into an integral structure.

[0028] Furthermore, a sealing film is provided between the tie plate and the prefabricated wall panel.

[0029] By adopting the above technical solutions, the sealing film transforms the prefabricated wall panels at the corresponding positions from a rigid combination to a flexible combination, making the connection between the prefabricated wall panels tighter, improving the anti-permeability performance at the connection, and more effectively enhancing the anti-permeability performance of the fully prefabricated composite concrete modular water tank for aquaculture composed of this type of product.

[0030] Furthermore, the L-shaped wall panel of the water storage aquaculture pond has an inner arc surface at its inside corner.

[0031] By adopting the above technical solutions, the inner arc design ensures that the water in the pool can circulate smoothly, without water flow obstruction forming dead corners, which would cause garbage accumulation and scale pollution.

[0032] Furthermore, a reinforced block formed by casting is provided between the bottom end of the outer wall of the enclosed isolation and protection body and the bottom plate.

[0033] By adopting the above technical solutions, the connection stability between the enclosure and the base plate can be improved, thereby enhancing the overall stability of the pool structure.

[0034] Furthermore, the counter-clamping component includes a clamping base plate, an adjusting insert, a sliding base plate, and a positioning base plate. There are two clamping base plates arranged opposite to each other. The connecting end of the prefabricated wall panel is located between the two clamping base plates, and a fixing member is provided between the two clamping base plates. The adjusting insert is connected to the top end of one of the clamping base plates and fits against the top wall of the prefabricated wall panel. The sliding base plate is connected to the top end of the other clamping base plate and fits against the top wall of the prefabricated wall panel. An adjusting groove is provided on the end wall of the positioning base plate. The adjusting insert is connected to the sliding base plate and is inserted into the adjusting groove and slidably connected to the groove wall. An auxiliary tensioning member is provided between the sliding base plate and the positioning base plate.

[0035] By adopting the above technical solution, the sliding substrate and the positioning substrate can overlap with the top wall of the precast wall panel. Combined with the auxiliary tensioning component, the adjusting insert slides in the adjusting groove, which can make the clamping substrate slightly clamped on the precast wall panel. This can help to position the clamping substrate and facilitate the subsequent tightening and fixing of the two clamping substrates using the fixing component.

[0036] In summary, this application has the following beneficial effects: 1. This application simplifies the assembly process at the construction site, allowing for one-time molding, which facilitates prefabricated installation and greatly shortens the on-site assembly time; 2. The fully prefabricated composite concrete modular aquaculture tank of this application is easier to clean, maintain and repair than existing welded tanks, and can better maintain the quality of the aquaculture water. 3. The fully assembled composite concrete modular water tank for aquaculture of the present application is structurally designed with prefabricated wall panels of the water storage aquaculture pond, the water quality purification pond and the enclosing isolation protection body, so that the whole water tank has high pressure resistance and greater flexibility; 4. The fully assembled composite concrete modular water tank for aquaculture of the present application adopts prefabricated wall panels made of concrete, and the joints are finally fixedly connected by pouring grout, which has stronger corrosion resistance.

[0037] 5. The present application is provided with a shaping frame structure, which can not only support the prefabricated wall panels during the construction process, but also clean the corner positions where garbage is easy to accumulate during the subsequent use of the water tank, and has a simple structure, which is conducive to popularization.

[0050] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0051] Example like Figure 1 As shown, this embodiment provides a fully prefabricated composite concrete modular aquaculture tank. For the complete tank structure, the tank includes a base plate 1 and a water storage and aquaculture tank 2, a water purification tank 3, and an enclosing isolation and protective structure 4 installed on the base plate 1. In this embodiment, the water storage and aquaculture tank 2, the water purification tank 3, and the enclosing isolation and protective structure 4 are all rectangular. The water purification tank 3 is located on the outer periphery of the water storage and aquaculture tank 2, and the enclosing isolation and protective structure 4 is located on the outer periphery of the water purification tank 3. The tank walls of the water storage and aquaculture tank 2 and the water purification tank 3 are polished to maintain a smooth surface, ensuring that no scale remains on the tank walls and facilitating cleaning and maintenance.

[0052] like Figure 2 and Figure 3As shown, the aquaculture tank 2, water purification tank 3, and enclosed isolation and protection body 4 of this application are all constructed by secondary casting of precast wall panels 5 on a base slab 1. The base slab 1 has a bottom groove 11 for grouting and fixing the precast wall panels 5. Specifically, the aquaculture tank 2, water purification tank 3, and enclosed isolation and protection body 4 are all assembled from structures including precast wall panels 5, tie rods 6, and sealing adhesive 7. Furthermore, the precast wall panels 5 form grouting bodies at the positions of the tie rods 6 and in the bottom groove 11. Simultaneously, a cast-in-place reinforcing block 15 can be formed between the bottom of the outer wall of the enclosed isolation and protection body 4 and the base slab 1. The precast wall panels 5 are made of concrete, and the specific material can be selected as needed. The precast wall panels 5 can also be reinforced with embedded steel bars.

[0053] For the base slab 1, it can also be prefabricated in three parts: the outer perimeter, the inner perimeter, and the middle section. The side walls of the prefabricated modules can be embedded with protruding reinforcing bars. Subsequently, the prefabricated modules of the base slab 1 are laid on the foundation layer, the reserved reinforcing bars are lapped and tied together, and then the inner perimeter concrete slab of the base slab 1 is poured a second time. Regarding the bottom trench 11 on the base slab 1 of this application, depending on the water tank structure, the bottom trench 11 on the base slab 1 includes an inner wall panel trench 12 for assembling the prefabricated wall panels 5 of the water storage and aquaculture tank 2, a central blocking panel trench 13 for assembling the water purification tank 3, and an outer wall panel trench 14 for assembling the prefabricated wall panels 5 of the enclosing isolation and protective structure 4. The shape of the bottom trench 11 can be an inverted trapezoid to facilitate the pouring of grout.

[0054] like Figure 2 , Figure 3 and Figure 4 As shown, the precast wall panel 5 of the aquaculture tank 2 includes a straight wall panel 51 and an L-shaped wall panel 52. The aquaculture tank 2 is formed by assembling the end walls of the straight wall panel 51 and the L-shaped wall panel 52 to form the inner wall panel of the tank. The L-shaped wall panel 52 is located at the corner of the aquaculture tank 2. Moreover, the inside corner of the L-shaped wall panel 52 is provided with an inner arc surface 55. The appropriate number of precast wall panels 5 of corresponding shapes can be selected according to the construction needs. For the straight wall panel 51 and the L-shaped wall panel 52, the connection between adjacent precast wall panels 5 is fixed by tie clamps 6.

[0055] The prefabricated wall panels 5 of the water purification pool 3 and the enclosed isolation and protection body 4 include “I”-shaped wall panels 51, “L”-shaped wall panels 52 and “O”-shaped irregular wall panels 53. Specifically, the end walls of the three types of prefabricated wall panels 5 of the water purification pool 3 form a central blocking plate; the enclosed isolation and protection body 4 forms an external wall panel by the end walls of the three types of prefabricated wall panels 5.

[0056] like Figure 3 , Figure 6 and Figure 7 as shown, it should be noted that the π-shaped special-shaped wall panel 53 includes two parallel side panels, and one main panel jointly connected to the end walls of the same side of the two side panels. The frame shape of the middle partition baffle of the water purification tank 3 and the outer wall panel of the enclosing isolation protection body 4 is mainly formed by fixing the end walls of the main panels of the I-shaped wall panel 51, the L-shaped wall panel 52 and the π-shaped special-shaped wall panel 53 through the opposite-pulling clamping member 6; at the same time, the two side panels of the π-shaped special-shaped wall panel 53 are both arranged toward the middle of the water tank, and the end walls of the two side panels of the π-shaped special-shaped wall panel 53 are connected to the opposite prefabricated wall panel 5 through the seal adhesive member 7, which is formed by applying structural sealant. In addition, the number and installation sequence of the I-shaped wall panels 51 and the π-shaped special-shaped wall panels 53 used can be determined according to actual working conditions.

[0057] Besides, as shown in Figure 7 , two adjacent plate bodies of the π-shaped special-shaped wall panel 53 are provided with reserved water passing grooves 54, that is, the two side panels of the π-shaped special-shaped wall panel 53 are provided with reserved water passing grooves 54. The specific number of the π-shaped special-shaped wall panels 53 provided with the reserved water passing grooves 54 is determined according to working conditions, and can be determined according to the required water flow direction, that is, as shown in Figure 1 the water flow direction indicated by the arrow direction therein.

[0058] As shown in Figure 3 and Figure 5 , in this embodiment, the opposite-pulling clamping member 6 includes two opposite-pulling clamping plates 61 and a set of opposite-pulling bolt and nut 62. The connecting end of the prefabricated wall panel 5 to be connected is located between the two opposite-pulling clamping plates 61, and at the same time, a sealing rubber sheet 63 is arranged between the opposite-pulling clamping plate 61 and the prefabricated wall panel 5, and the opposite-pulling bolt and nut 62 is fixed between the two opposite-pulling clamping plates 61. After the position of the prefabricated wall panel 5 is fixed, grouting material is poured into the gap between the connection part of the prefabricated wall panel 5 and the two opposite-pulling clamping plates 61, so as to realize the sealing between the prefabricated wall panels 5, and form a complete whole between the bottom plate 1 and the prefabricated wall panel 5. In addition, exposed steel bars can also be embedded at the connecting end of the prefabricated wall panel 5 to improve the stability of grouting anchoring; and for the water storage aquaculture tank 2, an inclined bottom wall can be poured at the tank bottom to facilitate cleaning and drainage.

[0059] As shown in Figure 8 , Figure 9 and Figure 10 , the bottom plate 1 located at the corner of the prefabricated wall panel 5 is provided with a liftable shaping frame 9, in which Figure 1For example, the corner of the precast wall panel 5 where the shaping frame 9 is located can be the corner of the "L"-shaped wall panel 52, or it can be the connection point between the side panel and the main panel of the "O"-shaped irregular wall panel 53. The specific location of the shaping frame 9 can be determined according to the actual working conditions. In this embodiment, for the sake of aesthetics and clarity of the attached drawings, only the corner of the precast wall panel 52 is used. Figure 1 Six shaping frames 9 are provided. Specifically, three support rods 96 are installed on the inner side wall of the shaping frame 9. The support rods 96 and the shaping frame 9 are slidably connected in the vertical direction. The support rods 96 and the shaping frame 9 are positioned by friction. The bottom wall of the support rods 96 is fixedly connected to the base plate 1.

[0060] like Figure 9 and Figure 10 As shown, the shape of the shaping frame 9 extends horizontally along the corner shape of the precast wall panel 5, wherein the shape of the shaping frame 9 in this embodiment is L-shaped; a receiving groove 91 is provided on the outer side wall of the shaping frame 9; wherein, there is a gap between the bottom wall and the top wall of the receiving groove 91 and the opposite precast wall panel 5, that is, there is a gap with the corner side wall of the "L"-shaped wall panel 52, or a gap with the side wall at the connection between the side plate and the main plate of the "O"-shaped irregular wall panel 53. Moreover, the gap of the top wall of the receiving groove 91 is larger than the gap of the bottom wall, so the position where the bottom wall of the receiving groove 91 protrudes relative to the top wall can form a sliding support plate 941.

[0061] The main function of the receiving groove 91 is to accommodate a detachable sizing block 92 or cleaning brush 93 connected to the sizing frame 9. The sizing block 92 or cleaning brush 93 is connected to the sizing frame 9 via a detachable part 94. The sizing block 92 or cleaning brush 93 also slides horizontally on the sizing frame 9 via a sliding part 95, and the sizing block 92 or cleaning brush 93 is close to the precast wall panel 5 under the action of the sliding part 95. In this embodiment, during the process of not installing the precast wall panel 5 and installing the precast wall panel, the sizing block 92 is installed in the receiving groove 91, and the sizing block 92 is provided with a plurality of sizing arc strips 99 on the side wall facing the precast wall panel 5. The axial direction of the sizing arc strips 99 is vertical and the arc surface is used to abut against the precast wall panel 5. When the installation of the precast wall panel 5 is completed, the cleaning brush 93 is installed in the receiving groove 91. In this embodiment, the cleaning brush 93 may include a base block and a brush head installed on the base block, wherein the brush head is mainly in contact with the side wall of the precast wall panel 5.

[0062] like Figure 9 and Figure 10As shown, the detachable component 94 in this embodiment includes a shifting shaft 942 and a friction plate 943. The friction plate 943 is rotatably connected to the top wall of the shaping frame 9 via the shifting shaft 942, and the friction plate 943 and the shaping frame 9 are positioned by friction. When installing the shaping block 92 or the cleaning brush 93, the friction plate 943 is rotated onto the shaping frame 9 to clear the space above the sliding support plate 941. Then, the shaping block 92 or the cleaning brush 93 is placed on the sliding support plate 941, and then the friction plate 943 is rotated so that the top wall of the shaping frame 9 and the shaping block 92 are both in contact with the bottom wall of the friction plate 943, or so that the top wall of the shaping frame 9 and the top wall of the base block of the cleaning brush 93 are both in contact with the bottom wall of the friction plate 943, thereby realizing the detachable installation of the shaping block 92 or the cleaning brush 93.

[0063] like Figure 9 , Figure 10 and Figure 11 As shown, the sliding member 95 in this embodiment includes a clamping stud 951, a pushing block 952, and a force-receiving inclined block 953. The force-receiving inclined block 953 is slidably disposed in the receiving groove 91. Specifically, a guide block 97 is provided on the bottom wall of the force-receiving inclined block 953, and a guide groove 98 is provided in the receiving groove 91. The guide block 97 is slidably disposed on the groove wall of the guide groove 98 along the diagonal direction of the shaping frame 9. The inclined surface of the force-receiving inclined block 953 is disposed facing the inside of the receiving groove 91, and the upper part of the inclined surface is inclined towards the groove opening of the receiving groove 91. In addition, by controlling the structural material, the side wall of the force-receiving inclined block 953 away from the receiving groove 91 is attached to and magnetically connected to the side wall of the shaping block 92 or the cleaning brush 93. A clamping stud 951 is threaded onto the top wall of the shaping frame 9 and extends into the receiving groove 91. A push block 952 is located at the bottom end of the clamping stud 951. The bottom wall of the push block 952 is spherical and abuts against the inclined surface of the force-bearing inclined block 953. Therefore, rotating the clamping stud 951 causes it to feed threadedly, which in turn causes the push block 952 to press against the inclined surface of the force-bearing inclined block 953, causing the shaping block 92 or cleaning brush 93 to move toward the precast wall panel 5. When the push block 952 moves away from the force-bearing inclined block 953, the force-bearing inclined block 953 is no longer under force, and the friction between the shaping block 92 or cleaning brush 93 and the precast wall panel 5 decreases. A slight movement can then move the shaping block 92 or cleaning brush 93 away from the precast wall panel 5. Alternatively, a return spring can be connected between the force-bearing inclined block 953 and the receiving groove 91. When the pushing block 952 moves away from the force-bearing inclined block 953, the return spring's return force, combined with the magnetic attraction of the force-bearing inclined block 953 to the shaping block 92 or cleaning brush 93, automatically drives the shaping block 92 or cleaning brush 93 away from the precast wall panel 5. In addition, an anti-fouling layer can be coated on the side wall of the shaping frame 9 to reduce the adhesion of debris on the shaping frame 9. The anti-fouling layer can be made of commercially available anti-fouling coatings, depending on the working conditions.

[0064] In this embodiment, the construction process of the fully assembled composite concrete modular water tank for aquaculture is as follows: First, according to the required cleaning position and supporting position, the shaping frame 9 is poured on the bottom plate 1 through the support rod 96, at this time the shaping block 92 is mounted on the shaping frame 9, then the prefabricated wall panel 5 is installed, in particular, for the side plate of the special-shaped wall panel 53 in the shape of "丌", the shaping block 92 is used to clamp it for preliminary positioning, which facilitates subsequent pouring and positioning, then other prefabricated wall panels 5 are installed according to the required water flow direction, and the opposite-pulling clamping members 66 are used for fixing at the fixed positions. After the installation of the prefabricated wall panels 5 is completed, the shaping block 92 is removed, the cleaning brush 93 is mounted on the shaping frame 9, in the subsequent working process of the water tank, if the tank wall needs to be cleaned, the pressing stud 951 is rotated to make the cleaning brush 93 fully fit the side wall of the prefabricated wall panel 5, then the shaping frame 9 is driven to move up and down manually or by a machine to complete the cleaning of the corners of the prefabricated wall panel 5, and the cleaning brush 93 can also be cleaned after a period of time. In addition, in order to facilitate the movement of the shaping frame 9, a force-bearing structure such as a hook can be arranged on the top wall of the shaping frame 9.

[0065] This specific embodiment is only an explanation of the present application, and is not a limitation of the present application. Those skilled in the art can make non-creative modifications to this embodiment as needed after reading this specification, but all shall be protected by the patent law as long as they fall within the scope of the claims of the present application.
