Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology for agricultural applications, and in particular to a modular, rapid-assembly intelligent well house. Background Technology

[0002] Intelligent well houses need to be used in outdoor environments for a long time and must withstand complex working conditions such as wind and rain erosion, sun aging, salt and alkali corrosion and external impact. Therefore, the structural strength, sealing and protection performance, assembly efficiency and transportation convenience of the well house directly determine its safety, operational stability and large-scale promotion value.

[0003] Traditional intelligent well houses are often installed by casting concrete foundations on-site and splicing them together with corrugated steel plates or fiberglass panels, or by fixing them on-site with a welded steel cabinet.

[0004] When assembling traditional panels piece by piece, each panel must be aligned and the connectors tightened.

[0005] However, traditional intelligent well houses and existing prefabricated products have the following technical problems during installation and construction, specifically in the following two aspects:

[0006] On the one hand, the construction process of concrete foundations is complicated, requiring the sequential completion of steps such as formwork support, staged pouring, and curing. Furthermore, formwork support relies on a professional construction team, and the formwork needs to be dismantled after completion, making the operation difficult and the construction cycle long.

[0007] On the other hand, existing prefabricated well houses are mostly made of fiberglass panels, which have poor overall strength and cannot withstand strong wind loads. In addition, each panel needs to be positioned and spliced ​​on-site to form the main body of the well house, which requires high professional skills from the construction personnel.

[0008] Therefore, designing a modular, rapidly assembled intelligent well house that can withstand severe weather is of great practical significance. Summary of the Invention

[0009] To solve one of the aforementioned technical problems, the present invention adopts the following technical solution: a modular, rapidly assembled intelligent well house, comprising a well house body. After installation, the bottom of the well house body is cast and fixed in a ground foundation pit. Reinforced structures formed by the solidification of concrete slurry are formed inside, in the middle, and outside of the well house body. A water pump unit is installed in the central cavity of the well house body. A protective unit is fitted onto the upper part of the well house body. The lower two sides of the protective unit are locked to the well house body by locks. A heat exchange channel is formed between the protective unit and the outer wall of the well house body. The water inlet of the water pump unit is used to connect to the underground well pipeline, and the water outlet extends to the outside of the well house body through a water supply pipe.

[0010] Based on any of the above technical solutions, a further optimization is made as follows: the steel cylinder is arranged vertically, with its top and bottom both open, a central cavity is provided inside the steel cylinder, an annular casting cavity is provided inside the outer wall of the steel cylinder, the bottom of the casting cavity is connected to the ground pit, and a reinforcing structure is provided at the lower part of the steel cylinder, the reinforcing structure being placed inside the ground pit.

[0011] Based on any of the above technical solutions, a further optimization is made as follows: the reinforcement structure includes inner grouting holes and outer grouting holes evenly distributed on the inner and outer walls of the casting cavity. Each inner grouting hole is connected to the lower part of the central cavity, and the outer grouting hole is connected to the ground foundation pit. A grouting pipe joint is welded on the lower outer wall of the rear side of the steel cylinder. The inner end of the grouting pipe joint is connected to the casting cavity and the central cavity, and the outer end is connected to the grouting equipment. After grouting is completed, it is in a sealed state.

[0012] Based on any of the above technical solutions, a further optimization is made as follows: a number of radial fins are uniformly welded along the circumference of the outer wall of the steel cylinder of the reinforced structure, and a number of ring bars are arranged from top to bottom on the lower periphery, with each ring bar passing through each radial fin in the circumferential direction; after the ground pit is filled with concrete slurry, each radial fin and ring bar is covered by it and forms a steel reinforcement skeleton.

[0013] Based on any of the above technical solutions, a further optimization is made as follows: a horizontally arranged lifting plate is coaxially installed in the lower part of the central cavity, the outer wall of the lifting plate is movably engaged with the inner wall of the central cavity, and a reinforced structure is cast into the central cavity below the lifting plate.

[0014] Based on any of the above technical solutions, a further optimization is made as follows: a load-bearing platform is fixedly welded to the center of the central cavity, and the water pump set is installed on the load-bearing platform. The water outlet of the water pump set passes through the connecting pipe at the lower front of the steel cylinder via a water supply pipe and extends to the outside to connect with the water-using equipment. A lifting assembly is installed in the central cavity above the water pump set. A network controller is installed on the lifting assembly. The controller is connected to the water pump set via a two-way signal. The top of the lifting assembly is fixed to the protective unit and moves with it.

[0015] Based on any of the above technical solutions, a further optimization is made as follows: the lifting assembly includes an inner cylinder that is fitted into the central cavity, a heat dissipation mesh plate is installed on the upper part of the inner cavity of the inner cylinder, the controller is installed at the bottom of the heat dissipation mesh plate, and a number of side wall heat dissipation holes are evenly distributed on the outer wall surface of the inner cylinder above the heat dissipation mesh plate. After installation, each of the side wall heat dissipation holes is located above the main body of the well house, and the top of the inner cylinder is open and fixed in the protective unit.

[0016] Based on any of the above technical solutions, a further optimization is made as follows: the protective unit includes an outer casing sleeved on the upper outer side wall of the main body of the well house, the top of the outer casing is sealed, an outer support ring is coaxially fixed to the upper outer side wall of the steel cylinder, the outer side wall of the outer support ring is clearance-fitted with the inner side wall of the outer casing, and a number of lower heat dissipation holes are evenly distributed along the circumference of the top of the outer support ring, forming an annular heat exchange channel between the outer casing and the outer side wall of the steel cylinder.

[0017] Based on any of the above technical solutions, a further optimization is made as follows: several vertical springs are evenly distributed along the circumference of the annular heat exchange channel, with the bottom of each vertical spring abutting against the top of the outer support ring and the top abutting against the top of the cavity of the outer protective cylinder.

[0018] Based on any of the above technical solutions, a further optimization is made as follows: two interlocking semi-circular flange covers are installed on the top of the reinforced structure. The two semi-circular flange covers fit together and cover the outer wall of the steel cylinder, and each semi-circular flange cover extends into the reinforced structure in the pit through connecting bolts.

[0019] Based on any of the above technical solutions, a further optimization is made as follows: chains are hinged to both sides of the lower outer side wall of the outer casing, each chain being used to engage with a bolt head welded to the middle outer side wall of the steel cylinder, and a lock hole is provided at the end of the bolt head for locking with a matching lock.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention adopts a modular prefabrication and rapid assembly design, dividing the main body of the well house into prefabricated well house components and post-installed prefabricated components, realizing the construction mode of off-site prefabrication and on-site hoisting assembly, which greatly reduces cumbersome procedures such as on-site welding and formwork construction.

[0022] Meanwhile, the steel cylinder has its own casting cavity structure, eliminating the need for additional internal and external formwork during casting, thus saving the formwork removal process. This shortens the construction cycle of medium-sized well houses and improves the construction efficiency of large well houses, making it suitable for the rapid deployment needs of complex outdoor construction sites and reducing the difficulty of construction organization and labor costs.

[0023] 2. This invention constructs a three-in-one load-bearing system of steel cylinder-reinforced skeleton-concrete reinforced structure. The radial fins and ring bars are welded to form a mesh skeleton. Combined with the integrated continuous casting process, the skeleton and concrete are tightly interlocked, which greatly improves the structure's resistance to wind load, settlement and pull-out.

[0024] This structure can transform horizontal wind loads into overall force, avoiding local stress concentration. Compared with the traditional tied steel reinforcement skeleton, it has improved pull-out resistance and can stably adapt to the outdoor heavy-load conditions of medium and large well houses, solving the technical problem of unstable pre-embedded fixation in large well houses.

[0025] 3. This invention achieves a synergistic integration of anti-theft protection and heat dissipation buffer. By rotating the prefabricated component 180° after installation to form a double-opening shield, and in conjunction with the weight of the chain lock and the outer protective cylinder, a multi-level anti-theft structure is formed, which can greatly increase the difficulty of theft even if the lock fails.

[0026] Meanwhile, the heat exchange channel between the outer casing and the steel cylinder enables airflow convection heat dissipation, and the vertical spring and airflow damping work together to dampen vibration, taking into account both the equipment's heat dissipation requirements and impact resistance performance. This solves the contradiction between heat dissipation and anti-theft in traditional well houses, and extends the service life of core components such as water pump sets and controllers.

[0027] 4. This invention adopts a screenless built-in intelligent control design. The existing controller integrates BLE5.0 Bluetooth and WIFI dual wireless modules, supporting short-range debugging and long-range data monitoring. Staff can read water pump operating parameters, receive fault alarms, and remotely start and stop control through a mobile APP.

[0028] During equipment maintenance, only unlocking and lifting of the outer casing are required for operation; there is no need to disassemble the complex structure on-site. Simultaneously, the vibration alarm module can push abnormal information in real time, achieving integrated anti-theft and fault early warning, thus improving the intelligent operation and maintenance level and operational safety of the well house.

[0039] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore merely examples and should not be used to limit the scope of protection of the present invention. The specific structure of the present invention is as follows: Figures 1-8 As shown in the image.

[0040] Example 1: A modular, rapid-assembly intelligent well house. The intelligent well house referred to in this invention specifically refers to medium-sized and large-sized intelligent well houses, including a well house body. After installation, the bottom of the well house body is cast and fixed in the ground foundation pit. Reinforced structures 23 formed by the solidification of concrete slurry are formed inside, in the middle and outside of the well house body. A water pump set 11 is installed in the central cavity 2 of the well house body. A protective unit is sleeved on the upper part of the well house body. The lower two sides of the protective unit are locked to the well house body by locks. A heat exchange channel 21 is formed between the protective unit and the outer wall of the well house body. The water inlet end of the water pump set 11 is used to connect to the underground well pipeline, and the water outlet end extends to the outside of the well house body through the water supply pipe 12.

[0041] The main body of the well house is fixed to the ground foundation pit by bottom pouring. The concrete grout solidifies inside, in the middle and outside of the main body to form an integrated reinforced structure 23, realizing the rigid connection between the main body of the well house and the foundation and the overall structural reinforcement. The water pump set 11 is installed inside the central cavity 2. It obtains water source by connecting to the underground well pipeline through the water inlet end, and delivers water to the external water-using equipment through the water supply pipe 12 at the water outlet end. The protective unit is assembled on the upper part of the main body of the well house by a sleeve method. It is mechanically locked by the locks on both sides, and at the same time forms an annular heat exchange channel 21 with the outer wall of the main body of the well house. The internal and external convection heat dissipation is completed by the air convection entering from the lower part.

[0042] The design employs a full-area casting method, which significantly improves the wind load and settlement resistance of the main structure of the well house compared to the traditional partial pre-embedded fixing method, making it suitable for the outdoor use needs of medium and large well houses. The integrated design of the protective unit and heat exchange channel 21 eliminates the need for additional heat dissipation devices or anti-theft shells, achieving functional integration and using locks to lock in conjunction with the sleeve structure to form double physical protection. This avoids anti-theft loopholes caused by the failure of a single locking mechanism, thereby improving the security of outdoor equipment.

[0043] Based on any of the above technical solutions, a further optimization is made as follows: the steel cylinder 1 is arranged vertically, with its top and bottom both open. A central cavity 2 is provided inside the steel cylinder 1, and an annular casting cavity 3 is provided inside the outer wall of the steel cylinder 1. The bottom of the casting cavity 3 is connected to the ground pit. A reinforcing structure is provided at the lower part of the steel cylinder 1, and the reinforcing structure is placed inside the ground pit.

[0044] The main body of the well house uses a steel cylinder 1 as the core rigid support component. The open design at the top and bottom provides space for the assembly of the protective unit and the pouring of the foundation pit, respectively. The central cavity 2 inside the steel cylinder 1 serves as the installation carrier for the water pump group 11 and the lifting assembly. The annular pouring cavity 3 inside the outer wall provides a filling channel for the concrete slurry. The bottom of the pouring cavity 3 is connected to the foundation pit on the ground, so that the slurry can fill the pouring cavity 3 and the foundation pit simultaneously, forming an integrated structure of steel cylinder 1, concrete pouring cavity 3, and foundation pit concrete. The lower reinforcement structure is embedded in the foundation pit on the ground. By combining with the solidified concrete slurry, it further strengthens the connection strength between the steel cylinder 1 and the foundation and restricts the radial and axial displacement of the steel cylinder 1. The steel cylinder 1 serves as both a casting template and a permanent load-bearing component, eliminating the need for additional temporary templates and subsequent demolding, thus greatly simplifying the construction process and meeting the requirements of rapid assembly. The annular casting cavity 3 allows the concrete slurry to evenly coat the outer wall of the steel cylinder 1, forming a symmetrical load-bearing structure, avoiding local stress concentration, improving the main body of the well house's resistance to horizontal wind loads, and making it suitable for heavy loads and strong wind conditions in medium and large well houses.

[0045] The pouring cavity 3 can serve as a buffer cavity for the flow of grout during the grouting process, avoiding excessive grout flow rate that could lead to localized incomplete filling. It also facilitates the observation of grout filling progress and improves the controllability of the pouring construction. The open structure of the steel cylinder 1, in conjunction with the pouring cavity 3, allows for air circulation during the concrete solidification process, reducing residual air bubbles inside the grout and improving the density and strength of the reinforced structure 23.

[0046] Based on any of the above technical solutions, a further optimization is made as follows: the reinforcement structure includes inner grouting holes 4 and outer grouting holes 5 evenly distributed on the inner and outer walls of the casting cavity 3. Each inner grouting hole 4 is connected to the lower part of the central cavity 2, and the outer grouting hole 5 is connected to the ground foundation pit. A grouting pipe joint 6 is welded on the lower outer wall of the rear side of the steel cylinder 1. The inner end of the grouting pipe joint 6 is connected to the casting cavity 3 and the central cavity 2, and the outer end is connected to the grouting equipment. After grouting is completed, it is in a sealed state.

[0047] During grouting, high-pressure grout enters the casting cavity 3 through the main channel of the grouting pipe joint 6. At the same time, some grout continues to flow into the lower part of the central cavity 2. Under the action of grouting pressure, the grout fills the lower part of the central cavity 2 along the connecting port and the inner grouting hole 4, and overflows to the ground foundation pit along the outer grouting hole 5, forming an integrated continuous casting space of the casting cavity 3, the central cavity 2, and the ground foundation pit.

[0048] Based on any of the above technical solutions, a further optimization is made as follows: a number of radial fins 7 are uniformly welded along the circumference of the outer wall of the steel cylinder 1 in the reinforced structure, and a number of ring ribs 8 are arranged from top to bottom on the lower periphery, with each ring rib 8 passing through each radial fin 7 in the circumferential direction; after the ground pit is filled with concrete slurry, each radial fin 7 and ring rib 8 is covered by it and forms a steel reinforcement skeleton.

[0049] The radial fins 7 are made of steel plates with a thickness of 8-12mm and are evenly distributed at equal angles along the circumference of the steel cylinder 1 (numbering 8-12). The radial length of the fins extends 50-120mm beyond the outer wall of the steel cylinder 1, and the bottom of the fins extends to be flush with the bottom end of the steel cylinder 1. The ring ribs 8 are made of HRB400 threaded steel with a diameter of 16-20mm and are arranged in several layers along the axial spacing of the steel cylinder 1. Each ring rib 8 has a through hole that matches the radial fins 7. During assembly, the ring ribs 8 pass through the fins and are welded to the fins to form a mesh-like steel reinforcement skeleton structure.

[0050] During pouring, the concrete slurry wraps around the radial fins 7 and the ring reinforcement 8 to form a composite structure. The fins disperse the radial load on the main body of the well house along the radial direction, while the ring reinforcement 8 constrains the deformation of the fins along the circumferential direction. Together, they form a three-dimensional load-bearing skeleton, which transforms the vertical pressure and horizontal wind load of the main body of the well house into the overall load of the skeleton, avoiding local stress concentration that could lead to structural cracking.

[0051] Meanwhile, the welding joint between the fins and the ring reinforcement 8 increases the bonding area between the steel skeleton and the concrete, improves the interfacial bonding strength, and prevents the skeleton from peeling off from the concrete.

[0052] The modular assembly design of the fins and ring reinforcement 8 eliminates the need for on-site steel reinforcement frame construction, allowing for completion solely through prefabrication and welding, significantly shortening the construction cycle and meeting the requirements for rapid modular assembly. Furthermore, the standardized size design can be flexibly adjusted according to the size of the well house. Medium and large well houses can achieve stress adaptation by increasing or decreasing the number of fins and adjusting the spacing of the ring reinforcement 8, improving the versatility of the solution. Moreover, the mesh frame structure makes the concrete more evenly stressed, distributing the horizontal load to the entire cast structure under outdoor high wind load conditions, preventing the main body of the well house from tilting or cracking.

[0053] The fins not only bear the load, but also guide the flow of grout, reduce air bubbles generated during grouting, and improve the density of concrete. At the same time, the design of the 8 ring bars passing through the fins ensures that there are no weak nodes in the skeleton. Compared with the traditional tied steel reinforcement skeleton, the pull-out resistance is improved, which solves the problem of unstable pre-embedded fixing in large well houses.

[0054] During pouring, the concrete slurry encapsulates the skeleton to form a composite structure. The fins radially disperse the horizontal wind load and radial pressure borne by the main body of the well house, while the ring reinforcement 8 constrains the lateral deformation of the fins along the circumferential direction. Together, they transform the local load into the overall force of the skeleton, avoiding stress concentration. At the same time, the fins guide the slurry to flow radially, reducing air bubble residue. The welded joints increase the bonding area between the skeleton and the concrete, improve the interfacial adhesion, and prevent the skeleton from peeling off from the concrete, ultimately forming a reinforced load-bearing structure.

[0055] Compared with traditional planar frames, the mesh-like three-dimensional load-bearing skeleton has a stronger load-bearing capacity and significantly improved resistance to pull-out force and horizontal load, solving the problem of unstable pre-embedded fixation in large well houses; the fins have both load-bearing and slurry guiding functions, realizing the multi-functionality of a single structure.

[0056] In addition, the radial fins 7 can serve as heat dissipation ribs during the concrete setting process, accelerating the heat dissipation of the slurry and preventing shrinkage cracks caused by excessive internal and external temperature differences in the concrete, thereby improving the crack resistance of the reinforced structure 23. The welded skeleton of the ring ribs 8 and the fins can absorb the impact force through skeleton deformation when the main body of the well house is subjected to strong impact, preventing the steel cylinder 1 from being directly deformed, and providing an impact buffer function. The part of the fins that extends beyond the outer wall of the steel cylinder 1 can increase the contact area between the main body of the well house and the foundation pit soil, enhance the lateral constraint force of the soil on the well house, and further enhance the stability of the well house under conditions such as strong wind loads and earthquakes.

[0057] Based on any of the above technical solutions, a further optimization is made as follows: a horizontally arranged lifting plate 9 is coaxially installed at the lower part of the central cavity 2, the outer side wall of the lifting plate 9 is movably engaged with the inner side wall of the central cavity 2, and a reinforcing structure 23 is cast into the central cavity 2 below the lifting plate 9.

[0058] Before grouting, the lifting plate 9 is in its initial position, sealing the lower area of ​​the central cavity 2 and guiding the grout to fill precisely below the lifting plate 9. During the grouting process, the grout pressure pushes the lifting plate 9 to rise slowly and stop after it comes into contact with the fixed stop block 27 inside the central cavity 2. At this time, the grouting pressure will increase significantly, indicating that the grout has been filled to the preset height. At the same time, the grouting pressure is adjusted to complete the subsequent grouting. After the grout solidifies, a reinforcing structure 23 is formed below the lifting plate 9, and the lifting plate 9 and the surface of the reinforcing structure 23 are in contact.

[0059] Based on any of the above technical solutions, a further optimization is made as follows: a load-bearing platform 10 is fixedly welded to the middle of the central cavity 2, and the water pump set 11 is installed on the load-bearing platform 10. The water outlet of the water pump set 11 passes through the connecting pipe 13 on the lower front side of the steel cylinder 1 via the water supply pipe 12 and extends to the outside to connect with the water-using equipment. A lifting assembly is installed in the central cavity 2 above the water pump set 11. A network controller 14 is installed on the lifting assembly. The controller 14 is connected to the water pump set 11 in a two-way signal manner. The top of the lifting assembly is fixed to the protective unit and moves with it.

[0060] The load-bearing platform 10 is fixedly welded to the center of the central cavity 2, providing a stable mounting carrier for the water pump unit 11 and ensuring that the vibration of the water pump unit 11 during operation is not directly transmitted to the main body of the steel cylinder 1. The water pump unit 11 is connected to the water supply pipe 12 below the load-bearing platform 10 through a connector. The water supply pipe 12 passes through the connecting pipe 13 of the steel cylinder 1 and connects to the external water-using equipment to realize the extraction and transportation of underground water. The lifting assembly is installed in the central cavity 2 above the water pump unit 11, and its top is fixedly connected to the protective unit. It can be raised and lowered synchronously with the protective unit. The controller 14 is installed on the lifting assembly and is connected to the water pump unit 11 through a bidirectional signal line to realize real-time monitoring and remote control of the water pump operating parameters. When the protective unit is raised and lowered, it drives the lifting assembly and the controller 14 to move synchronously, which facilitates the wiring, debugging and subsequent maintenance of the controller 14 and the water pump unit 11.

[0061] The load-bearing platform 10 can serve as a partition structure inside the central cavity 2, dividing the central cavity 2 into upper and lower areas. The upper part is the equipment installation area, and the lower part is the reinforced structure 23 area. This avoids contamination of the equipment during the construction of the reinforced structure 23 and reduces the heat transfer from the equipment during operation to the lower reinforced structure 23. When the protective unit is pried, the lifting component can drive the controller 14 to rise synchronously, tightening the wiring between the controller 14 and the water pump group 11, triggering the alarm module of the controller 14, and improving the anti-theft early warning capability. In addition, the welded structure of the load-bearing platform 10 can also enhance the radial stiffness of the steel cylinder 1, preventing deformation of the middle part of the steel cylinder 1 due to stress, and further improving the overall stability of the well house.

[0062] Based on any of the above technical solutions, a further optimization is made as follows: the lifting assembly includes an inner cylinder 15 that is fitted into the central cavity 2, a heat dissipation mesh plate 16 is installed on the upper part of the inner cavity of the inner cylinder 15, the controller 14 is installed at the bottom of the heat dissipation mesh plate 16, and a plurality of side wall heat dissipation holes 17 are evenly distributed on the outer side wall surface of the inner cylinder 15 above the heat dissipation mesh plate 16. After installation, each of the side wall heat dissipation holes 17 is located above the main body of the well house, and the top of the inner cylinder 15 is open and fixed in the protective unit.

[0063] The lifting assembly uses the inner cylinder 15 inserted into the central cavity 2 as its core carrier. The inner cylinder 15 is fitted with the central cavity 2 with a clearance and its top is fixed in the protective unit, allowing it to rise and fall synchronously with the protective unit. The heat dissipation mesh plate 16 installed on the upper part of the inner cavity of the inner cylinder 15 divides the inner cylinder 15 into upper and lower areas. The lower part is used to install the controller 14, and the upper part is a heat dissipation channel. The heat generated by the controller 14 is transferred to the heat dissipation mesh plate 16, which increases the heat dissipation area. At the same time, outside air enters through the heat exchange channel 21, exchanges heat with the controller 14 through the heat dissipation mesh plate 16, and is discharged through the heat dissipation holes 17 on the side wall of the inner cylinder 15 (located above the main body of the well house). The side wall heat dissipation holes 17 are located above the main body of the well house, which can prevent rainwater from entering and ensure smooth airflow for heat dissipation, thus achieving efficient heat dissipation of the controller 14.

[0064] Based on any of the above technical solutions, a further optimization is made as follows: the protective unit includes an outer casing 18 sleeved on the upper outer side wall of the main body of the well house, the top of the outer casing 18 is sealed, an outer support ring 19 is coaxially fixed to the upper outer side wall of the steel cylinder 1, the outer side wall of the outer support ring 19 is clearance-fitted with the inner side wall of the outer casing 18, and a plurality of lower heat dissipation holes 20 are evenly distributed along the circumference of the top of the outer support ring 19, forming an annular heat exchange channel 21 between the outer casing 18 and the outer side wall of the steel cylinder 1.

[0065] The lower heat dissipation holes 20 have a diameter of 15-20mm and a number of 8-12. They are distributed at equal angles along the circumference of the outer support ring 19. With the shielding effect of the bottom of the outer casing 18, they can effectively prevent rainwater from entering the heat exchange channel 21 through the heat dissipation holes.

[0066] The radial width of the heat exchange channel 21 is 50-80mm. The inner wall of the outer casing 18 and the outer wall of the steel cylinder 1 are both treated with anti-rust coating. The outer casing 18 moves smoothly along the axial direction when it is raised or lowered.

[0067] When the well house is in operation, the heat generated by the water pump set 11 and the controller 14 is conducted to the heat exchange channel 21 through the side wall of the steel cylinder 1. At the same time, the cold air from the outside enters the heat exchange channel 21 through the lower heat dissipation hole 20, flows from bottom to top along the channel, exchanges heat with the side wall of the steel cylinder 1, and is discharged through the heat dissipation hole 17 on the side wall of the inner cylinder 15, ensuring smooth airflow and improving heat dissipation efficiency.

[0068] The heat exchange channel 21 serves both heat dissipation and buffering functions. The vertical spring 22 absorbs the vibration generated by external impacts, which can be attenuated by the airflow damping in the channel, reducing the impact of vibration on the internal water pump group 11 and controller 14, thus resolving the contradiction between heat dissipation and impact resistance in traditional well houses.

[0069] The outer casing 18 of the protective unit is assembled on the upper part of the well house body by means of a sleeve connection. The outer support ring 19 on the upper part of the steel cylinder 1 provides vertical support for the outer casing 18, and the outer support ring 19 is clearance-fitted with the inner side wall of the outer casing 18 to ensure that the outer casing 18 can be raised and lowered smoothly along the axial direction. The lower heat dissipation holes 20 (8-12 holes) are evenly distributed on the outer support ring 19. The outer casing 18 and the outer side wall of the steel cylinder 1 form a 50-80mm wide annular heat exchange channel 21. The inner wall of the channel is treated with anti-rust coating.

[0070] During operation, the heat generated by the water pump unit 11 and the controller 14 is conducted to the heat exchange channel 21 through the side wall of the steel cylinder 1. Outside cold air enters the channel through the lower heat dissipation hole 20, flows axially from bottom to top, exchanges heat with the side wall of the steel cylinder 1, and is discharged through the heat dissipation hole 17 on the side wall of the inner cylinder 15, forming a convective heat dissipation of cold air in, heat exchange, and hot air out. At the same time, the airflow in the heat exchange channel 21 can act as a damping medium to attenuate the vibration generated by the vertical spring 22 to absorb external impacts and reduce the impact of external impacts on the internal equipment.

[0071] Based on any of the above technical solutions, a further optimization is made as follows: several vertical springs 22 are evenly distributed along the circumference of the annular heat exchange channel 21, with the bottom of each vertical spring 22 abutting against the top of the outer support ring 19 and the top abutting against the top of the cavity of the outer protective cylinder 18.

[0072] Vertical springs 22 are evenly distributed around the circumference of the heat exchange channel 21, with their bottoms abutting against the top of the outer support ring 19 and their tops abutting against the top of the outer casing 18 cavity, forming an elastic support structure. When the outer casing 18 is subjected to downward pressure (such as during installation or when pressed by external heavy objects), the vertical springs 22 are compressed to absorb pressure energy and prevent rigid collision between the outer casing 18 and the outer support ring 19. When the outer casing 18 is subjected to upward tension (such as during maintenance lifting), the vertical springs 22 are stretched and reset to assist the outer casing 18 in smooth lifting and lowering. When the well house is subjected to external impact (such as collision or vibration from strong winds), the vertical springs 22 absorb impact energy through elastic deformation. At the same time, in conjunction with the airflow damping in the heat exchange channel 21, vibration transmission is attenuated, reducing the impact and vibration on the internal controller 14 and water pump group 11, thus achieving a synergistic effect of elastic buffering and vibration attenuation.

[0073] Based on any of the above technical solutions, a further optimization is made as follows: two interlocking semi-circular flange covers 24 are installed on the top of the reinforcing structure 23. The two semi-circular flange covers 24 fit together and cover the outer side wall of the steel cylinder 1, and each semi-circular flange cover 24 extends into the reinforcing structure 23 in the pit through connecting bolts.

[0074] Two semi-circular flange covers 24 are attached to the outer wall of the steel cylinder 1 by a butt joint, covering the top of the reinforcing structure 23. The connecting bolts pass through the semi-circular flange covers 24 and extend into the reinforcing structure 23 in the foundation pit. The semi-circular flange covers 24 are fixed to the reinforcing structure 23 and the steel cylinder 1 by bolt tightening. The semi-circular flange covers 24 adopt a split design, which is convenient for assembly after the concrete slurry has solidified. There is no need to reserve installation space before grouting, which is suitable for modular construction process.

[0075] Based on any of the above technical solutions, a further optimization is made as follows: a chain 25 is hinged to both sides of the lower outer side wall of the outer casing 18, and each chain 25 is used to engage with a bolt head 26 welded to the middle outer side wall of the steel cylinder 1. A lock hole is provided at the end of the bolt head 26 for locking with a matching lock.

[0076] The chains 25 on both sides of the lower part of the outer protective cylinder 18 are hinged to the outer protective cylinder 18 and can be rotated and adjusted flexibly. The bolt head 26 welded in the middle of the steel cylinder 1 provides a docking carrier for the chain 25. After the protective unit is installed in place, one end of the chain 25 is inserted into the bolt head 26 and locked by passing through the lock hole at the end of the bolt head 26 with the matching lock, so that the chain 25 is tightened and the outer protective cylinder 18 and the steel cylinder 1 are fixed as one, preventing the outer protective cylinder 18 from being raised, lowered or pried at will.

[0077] A lifting ring 28 is welded to the top of the outer casing 18. The lifting ring 28 facilitates the lifting of the outer casing 18 with the help of lifting equipment.

[0078] Example 2: Compared with Example 1, this example also includes the following technical features:

[0079] The present invention also provides a construction method for the above-mentioned modular rapid assembly intelligent well house, comprising the following steps:

[0080] S1 transports the various components of the intelligent well house to the construction site, completes the installation of the water pump group 11 in the central cavity 2 to form the well house pre-assembled parts, and completes the pre-assembly of the protection unit and lifting components to form the post-assembly prefabricated parts.

[0081] Step S1 involves disassembling and transporting the main body of the well house, pump set 11, protective unit, and lifting assembly, among other components. Pre-assembly is then completed off-site or near the construction location: firstly, the pump set 11 is installed inside the central cavity 2 of the steel cylinder 1, forming a pre-assembled well house component (core load-bearing and functional carrier); secondly, the protective unit and lifting assembly are assembled and fixed, forming a post-assembled prefabricated component (an integrated protective and control component). After pre-assembly, on-site hoisting and assembly are carried out, reducing on-site construction procedures, improving construction efficiency, and ensuring a controllable pre-assembly environment to guarantee assembly accuracy and avoid the impact of complex on-site environments on assembly quality. During pre-assembly, the pump set 11 and controller 14 can be pre-tested to identify equipment faults in advance, avoiding rework due to equipment problems after on-site assembly and reducing construction costs.

[0082] S2, after the ground foundation pit is completed, the pre-assembled well house components are hoisted into the ground foundation pit and adjusted to be vertical before pre-fixing is completed.

[0083] In practice, after the ground foundation pit is excavated, compacted, and leveled according to the design dimensions, a small hoisting device is used to hoist the prefabricated components of the well house into the foundation pit. The steel cylinder 1 is adjusted to a vertical state using tools such as a level and plumb bob (vertical deviation controlled within 0.5%) to ensure uniform stress on the subsequent poured structure. Temporary supports (such as diagonal braces and wooden blocks) are symmetrically arranged on the lower outer side of the steel cylinder 1 for pre-fixation, and fixed to the side wall of the foundation pit or the ground to constrain the horizontal displacement and tilt of the steel cylinder 1, preventing it from shifting due to external forces (such as wind or hoisting collisions) before grouting. The pre-fixing strength must meet the impact force and vibration requirements of the grout during the grouting process, and at the same time, it should be easy to remove later without affecting the formation of the reinforced structure 23.

[0084] S3, connect the grouting pipe joint 6 to the grouting equipment through the grouting pipeline, and inject the high-pressure conveyed fluid or highly fluid concrete slurry to ensure the smooth flow of the slurry.

[0085] S4 controls the grouting pressure and time and observes the grout flow direction. During the grouting process, continuous tapping of the main body of the well house achieves vibration, air release, and grout compaction.

[0086] The grout uses C30-C40 self-compacting concrete, with fluidity indicators controlled at a spread of 550-650mm and a slump of 220-250mm. Polycarboxylate-based high-efficiency water-reducing agent and air-entraining agent are added to the grout. The water-reducing agent dosage is 0.8-1.2% of the cementitious material mass, and the air-entraining agent dosage is 0.01-0.02%, ensuring that the grout can still fill each injection hole and gap under low pressure.

[0087] The grouting pressure is controlled at 0.3-0.5MPa. The grouting time for medium-sized well houses is 40-60 minutes, and for large well houses it is 60-90 minutes. During the grouting process, the pressure sensor of the equipment is used to monitor the pressure change in real time. When the pressure suddenly rises by more than 10%, it is determined to be a local grout blockage, and grouting needs to be stopped and the blockage needs to be cleared by tapping.

[0088] The selection of self-compacting concrete enables grout filling without vibration, reducing on-site vibration procedures and meeting the needs of rapid assembly construction; the combination of pressure monitoring and tapping to clear blockages can promptly resolve blockage issues during grouting, ensuring smooth grout flow and guaranteeing the integrity of the cast structure.

[0089] In addition, the micro-bubbles introduced by the air-entraining agent can form closed pores after the concrete solidifies, improving the frost resistance and impermeability of the cast structure, making it suitable for outdoor low temperature and humid environments. At the same time, the high density of the self-compacting concrete increases the structural strength compared to traditional casting, solving the problem of insufficient strength in traditional modular well house casting structures.

[0090] S5. During the grouting process, the fluid grout is controlled to fill the lower part of the central cavity 2 along each inner grouting hole 4, overflow into the ground foundation pit along each outer grouting hole 5, and fully fill the annular grouting cavity from bottom to top. The grouting pressure change is observed and the grouting stop time is controlled in a timely manner after the ground foundation pit is fully filled.

[0091] S6, after standing for 3-6 hours, assemble the two semi-circular flange covers 24 and position them using the connectors.

[0092] In specific operations, the grouting process involves controlling the grout flow path through the coordinated control of grouting pressure and grout fluidity, allowing the grout to fill simultaneously along three main paths: first, it flows into the lower part of the central cavity 2 through the inner grouting hole 4, filling the area below the lifting plate 9; second, it overflows to the ground foundation pit through the outer grouting hole 5, wrapping the radial fins 7 and the ring reinforcement 8; and third, it fully fills the annular casting cavity 3 from bottom to top, wrapping the outer wall of the steel cylinder 1. The staff observes the changes in grouting pressure and the filling status of the foundation pit in real time. When the ground foundation pit is observed to be fully filled with grout, the staff judges that each area has been filled densely based on the stable pressure status and stops grouting in time to avoid over-grouting, which could lead to grout waste or deformation of the steel cylinder 1, ensuring the continuous casting of the casting cavity 3, the central cavity 2, and the foundation pit into a single structure.

[0093] S7, after standing for 72-96 hours, the slurry solidifies to form a reinforced structure.

[0094] Steps S6-S7 are the concrete curing and flange cover assembly process. After grouting, let it stand for 3-6 hours. At this time, the concrete is in the initial setting state and has a certain strength, which can withstand the weight of the semi-circular flange cover 24 and the pressure of the connecting parts. At this time, assemble the two semi-circular flange covers 24 and position them with connecting bolts to avoid difficulties in flange cover assembly or damage to the concrete after the concrete has fully set. Then, let it stand for another 72-96 hours to allow the concrete to fully set and reach the design strength, forming a stable reinforced structure 23. At this time, tighten the flange cover bolts to the specified torque to ensure that the flange cover is firmly connected to the reinforced structure 23 and the steel cylinder 1, while ensuring the quality of concrete curing and avoiding premature stress that could cause structural cracking.

[0095] S8, install each vertical spring 22 on the top of the outer support ring 19, then continue to hoist the prefabricated parts and complete the wiring of the controller 14 and the water pump group 11 in advance and after the debugging is qualified, continue to lower and press down the entire outer casing 18 to the position.

[0096] It should be noted that before continuing to lower the prefabricated component, it should be rotated 180° so that the opening on the upper front side of the steel cylinder 1 is opposite to the opening on the lower front side of the inner cylinder 15. This ensures that after lowering, the opening of the inner cylinder 15 is blocked by the central cavity 2 and the upper opening of the steel cylinder 1 is blocked by the side wall of the inner cylinder 15, thereby improving the anti-theft effect.

[0097] The controller 14 comes with a built-in wireless communication module (including a Bluetooth module and a WIFI module) and an alarm module. Staff can directly connect to the controller 14 via a mobile device to perform data maintenance and record observation without the need for screen operation. All devices are equipped with built-in anti-theft features, further improving the anti-theft effect.

[0098] The Bluetooth module adopts the BLE5.0 protocol (communication distance of 10-20m) and is suitable for short-range debugging and data reading; the WIFI module supports the 802.11b / g / n protocol (communication distance ≤100m) to realize remote data monitoring and command issuance. The two modules automatically switch working modes (Bluetooth is given priority for short distances, and WIFI is automatically switched for long distances).

[0099] When the outer casing 18 is pried open (vibration value exceeds preset threshold), the controller 14 immediately sends alarm information (including location, time, and abnormality type) to the mobile terminal via wireless module, and at the same time activates the built-in buzzer (volume ≥ 80dB) for on-site alarm.

[0100] The mobile app is compatible, eliminating the need for on-site screen installation. It supports real-time data display (pump flow, pressure, operating status), historical data query, fault alarm push notifications, and remote start / stop control. All maintenance actions are completed via wireless commands, eliminating the need for on-site screen operation.

[0101] The upper front opening 101 of the steel cylinder 1 is for easy maintenance, and the lower front opening 1501 of the inner cylinder 15 facilitates observation of the interior during hoisting and lowering. During rotational positioning, using the bolt head 26 on the outer wall of the steel cylinder 1 as a reference, after rotating the prefabricated component 180°, the side wall of the inner cylinder 15 completely covers the rectangular through hole of the steel cylinder 1, while the inner side wall of the central cavity 2 blocks the wiring channel of the inner cylinder 15, forming a double shield. In addition, the fitting gap between the inner cylinder 15 and the steel cylinder 1 is controlled at 5-8mm to ensure smooth lifting and lowering of the inner cylinder 15 and prevent others from prying the opening through the gap.

[0102] After the prefabricated component is rotated, the two openings are positioned opposite each other, preventing external personnel from accessing the internal components through a single opening. The double shielding of the inner cylinder 15 side wall and the central cavity 2 side wall forms a physical anti-theft barrier. During operation and maintenance, simply rotating and resetting the prefabricated component will align the openings.

[0103] The double shielding structure makes the anti-theft effect not dependent on the single protection of the lock. Even if the lock fails, outsiders still need to break the double structure of the inner cylinder 15 and the steel cylinder 1 to access the internal components, which greatly increases the difficulty of theft prevention and solves the problem that traditional well house locks can be opened after the swing door is broken and the controller 14 and other components can be stolen. At the same time, the back-to-back opening design does not affect the normal assembly and maintenance of the internal components.

[0104] Step S8 is the process of installing, debugging and deploying the anti-theft structure of the post-installed prefabricated components. First, install the vertical spring 22 on the top of the outer support ring 19, then hoist the post-installed prefabricated components. Complete the wiring of the controller 14 and the water pump group 11 in advance and debug it to ensure that the equipment communication and control are normal.

[0105] S9, once in place, insert each chain 25 and bolt head 26 into place and lock them with the matching locks to ensure the stability of the outer casing 18.

[0106] When the equipment needs maintenance, simply unlock the lock and use the existing small lifting equipment to lift the outer casing 18, or two workers can use a ladder to climb up and lift the outer casing 18.

[0107] When used outdoors, this well house can achieve multi-level anti-theft by using the plug-in cover of the protective unit in conjunction with the lock. Even if the lock fails, the weight of the outer protective sleeve 18 can still provide anti-theft protection, increasing the difficulty of stealing the internal components and improving the anti-theft effect.

[0108] The overall structure of this intelligent well house relies on rigid support, while the internally poured concrete slurry solidifies to form a reinforced structure, thereby improving the overall strength of the well house and adapting to the stability under outdoor high wind load conditions.

[0109] Furthermore, the pouring construction of this well house relies on its own internal and external formwork, eliminating the need for formwork erection and subsequent formwork removal during pouring inside the pouring cavity 3. This significantly reduces the cumbersome on-site construction procedures and improves construction efficiency. Simultaneously, the overall wind resistance is ensured by external and internal rigid supports, with external rigid supports clamping the central concrete structure.

[0110] In addition, the lower part of the well house is pre-embedded and poured in one piece with the annular pouring of the pouring cavity 3 and the pouring of the central cavity 2, which ensures the structural integration after pouring and improves the pouring strength. During the pouring process, the radial fins 7 and the ring ribs 8 are covered by them and the steel skeleton formed is integrally formed with the slurry, without the need to build an additional steel skeleton, which improves efficiency while ensuring the strength of the poured structure.
