Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated modular buildings, specifically to a prefabricated modular rainwater storage tank. Background Technology

[0002] Existing rainwater storage tanks are generally constructed using ordinary prefabricated structures or on-site casting methods, where prefabricated water storage modules are assembled inside the foundation pit to achieve the purpose of water storage.

[0003] A Chinese patent with publication number CN207919724U discloses a prefabricated assembled rainwater storage tank. Its key technical features include: a top cover and a bottom plate; an inlet on the top surface of the top cover; a pouring port penetrating the top cover at the corner of the top cover; reinforcing bars connected to the concrete inside the bottom plate; a pouring area connected to the concrete at the corner of the bottom plate; and an installation groove on the upper surface of the bottom plate, which slidably connects to a downstream end wall, an upstream end wall, and a side wall. However, the aforementioned common rainwater storage tanks still have shortcomings:

[0004] Firstly, this simple splicing method has poor anti-buoyancy capabilities. It cannot be used in high-water areas where strong anti-buoyancy is required, as problems will arise due to its poor anti-buoyancy. Secondly, it lacks an overflow detection device. Ordinary water level detectors can only detect water levels within a set range. If there is a malfunction or blockage in the drainage system, the collected water cannot be discharged in time, and traditional water level detection devices may be unable to detect it, resulting in huge losses. Utility Model Content

[0005] This utility model provides a prefabricated, assembled rainwater storage tank that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: foundation pit;

[0007] An anti-buoyancy water storage mechanism is installed inside the foundation pit;

[0008] Multiple sheet piles are evenly installed on the four inner walls of the foundation pit;

[0009] A water inlet pipe is fixedly connected to one side of the top of the anti-buoyancy water storage mechanism;

[0010] The water outlet pipe is fixedly connected to the other side of the top of the anti-buoyancy water storage mechanism;

[0011] Several maintenance pipes are fixedly connected to the top of the anti-buoyancy water storage mechanism;

[0012] Several water level detection mechanisms are installed inside the anti-buoyancy water storage mechanism;

[0013] Several overflow water alarm mechanisms are installed on the inner wall of the inspection pipe.

[0014] Furthermore, the anti-buoyancy water storage mechanism includes a reinforced concrete base plate, and a plurality of stacked water storage components are provided on the top of the reinforced concrete base plate. One of the water storage components is provided with a concrete top plate on its top. The interior of the water storage component is provided with a plurality of connecting cavities, and the interior of the plurality of connecting cavities is filled with concrete columns.

[0015] The above technical solution helps to integrate the entire water storage structure into a whole, greatly enhancing its anti-buoyancy capability.

[0016] Furthermore, the water storage component includes four rectangularly arranged corner water storage boxes, each of the four corner water storage boxes is connected to multiple side water storage boxes, and multiple central boxes are provided between the corner water storage boxes and the side water storage boxes.

[0017] The above technical solution allows the water storage components to be assembled into a single unit.

[0018] Furthermore, positioning and reinforcing grooves are provided at the four corners of the top of the multiple water storage corner boxes, water storage side boxes and the middle box, and positioning and reinforcing columns are connected to the four corners of the bottom of the multiple water storage corner boxes, water storage side boxes and the middle box. Condensation grooves are provided on the surface of the water storage corner boxes, water storage side boxes and the middle box.

[0019] The above technical solution facilitates quick and easy installation, improves work efficiency, and increases the connection strength between various components.

[0020] Furthermore, the water level detection mechanism includes a float level gauge, one side of which is connected to a limiting ring, and the limiting ring is provided with a limiting rod inside. One end of the limiting rod is connected to the inside of one of the central boxes, and the other end of the limiting rod is connected to the bottom of the concrete top slab.

[0021] The above technical solution facilitates real-time monitoring of water levels.

[0022] Furthermore, the overflow water alarm mechanism includes a detection ring connected inside the inspection pipe. The inner wall of the detection ring has a detection slide, and a detection slider is slidably connected inside the detection slide. An alarm device is provided above the detection slider and is located on one side of the inner wall of the detection ring.

[0023] The above technical solutions are beneficial for indirectly detecting problems in drainage systems.

[0024] Furthermore, the alarm device includes a microcontroller, a pressure sensor, and a signal transmission module. The pressure sensor is electrically connected to the microcontroller, and the microcontroller is electrically connected to the signal transmission module.

[0025] The above-described solution of this utility model has at least the following beneficial effects:

[0026] 1. This utility model involves laying the bottom water storage modules on a concrete base slab installed inside the foundation pit. The concrete base slab has positioning and reinforcing grooves, and each water storage module has a corresponding positioning and reinforcing column at its bottom. This allows for quick positioning, accelerates construction efficiency, and strengthens the horizontal connection strength, connecting each layer together. Each water storage module has rounded corners, creating connecting cavities at the joints. Concrete is poured into these connecting cavities, thus connecting each layer of water storage modules together. A concrete top slab is then placed on top to form a unified structure, greatly enhancing the anti-buoyancy capability and improving construction efficiency.

[0027] 2. Although this utility model has a water level detection device inside the central box facing the inspection pipe, traditional water level detection generally has a fixed range, and detections outside the range are generally not considered. Therefore, if the discharge mechanism malfunctions or becomes blocked during the use of the rainwater storage tank, it may damage the surrounding equipment of the entire rainwater storage tank, causing serious losses. Therefore, when water overflows, an alarm device is installed at the connection between the inspection pipe and the concrete roof slab. Pressure is applied to the pressure sensor through a float, and when water overflows, the information is transmitted through the signal transmission module. Attached Figure Description

Detailed Implementation

[0036] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] like Figures 1 to 6 As shown, an embodiment of this utility model provides a prefabricated assembled rainwater storage tank, comprising:

[0038] Excavation Pit 1;

[0039] Anti-buoyancy water storage mechanism, which is installed inside the foundation pit 1;

[0040] Multiple sheet piles 3 are evenly installed on the four inner walls of the foundation pit 1.

[0041] Water inlet pipe 8 is fixedly connected to one side of the top of the anti-buoyancy water storage mechanism;

[0042] Water outlet pipe 9 is fixedly connected to the other side of the top of the anti-buoyancy water storage mechanism;

[0043] Several inspection pipes 10 are fixedly connected to the top of the anti-buoyancy water storage mechanism.

[0044] Several water level monitoring devices are installed inside the anti-buoyancy water storage mechanism;

[0045] Several overflow water alarm mechanisms are installed on the inner wall of the inspection pipe 10.

[0046] like Figure 4As shown, the anti-buoyancy water storage mechanism includes a reinforced concrete base plate 2, and multiple stacked water storage components 4 are provided on the top of the reinforced concrete base plate 2. One of the water storage components 4 is provided with a concrete top plate 7. The water storage component 4 has several connecting cavities 6 inside, and each of the several connecting cavities 6 is filled with concrete filling columns 5. The water storage component 4 includes four rectangularly arranged water storage corner boxes 41. Multiple water storage side boxes 42 are connected between each pair of the four water storage corner boxes 41. Multiple middle boxes 43 are provided between the water storage corner boxes 41 and the water storage side boxes 42. Positioning reinforcement grooves 45 are opened at the four corners of the top of the multiple water storage corner boxes 41, water storage side boxes 42 and middle boxes 43. Positioning reinforcement columns 44 are connected at the four corners of the bottom of the multiple water storage corner boxes 41, water storage side boxes 42 and middle boxes 43. Concrete grooves 46 are opened on the surface of the water storage corner boxes 41, water storage side boxes 42 and middle boxes 43.

[0047] In this embodiment, a reinforced concrete base slab 2 is laid at the bottom of the foundation pit 1, and positioning grooves are opened on the surface of the reinforced concrete base slab 2. Water storage corner boxes 41 are placed at the four corners of the reinforced concrete base slab 2, and water storage side boxes 42 are placed between the four water storage corner boxes 41. Connecting screws are provided on the two outer sides of the water storage corner boxes 41, and connecting screws are provided on both sides of one side of the water storage side boxes 42. During the placement process, a threaded sleeve is screwed onto one of the screws, and then the positioning is arranged according to the positions of the positioning reinforcement groove 45 and the positioning reinforcement column 44. After placement, the screws between the two are connected together by a screw sleeve, which helps to enhance the connection strength in the horizontal direction. The positioning mechanism can speed up the installation. Because each water storage box has rounded corners, a connection cavity 6 will appear at the connection point after they are placed together. After each layer is installed, concrete filling columns 5 are poured into each connection cavity 6 to firmly fix each layer of water storage components 4 together. Then, a concrete top plate 7 is laid on the top water storage component 4 to integrate the entire anti-buoyancy water storage mechanism into one unit, which greatly enhances the anti-buoyancy effect.

[0048] like Figure 5 As shown, the overflow water alarm mechanism includes a detection ring 12, which is connected inside the inspection pipe 10. A detection slide 13 is provided on the inner wall of the detection ring 12. A detection slider 14 is slidably connected inside the detection slide 13. An alarm device is provided above the detection slider 14 and is located on one side of the inner wall of the detection ring 12. The alarm device includes a microcontroller 15, a pressure sensor 16, and a signal transmission module 17. The pressure sensor 16 is electrically connected to the microcontroller 15, and the microcontroller 15 is electrically connected to the signal transmission module 17.

[0049] In this embodiment, when water overflows from the water storage mechanism, the liquid level will exceed the concrete top slab 7, causing the detection slider 14 to float. The detection slider 14 is a combination of an air bladder and a slider. Therefore, when water overflows, the air bladder will cause the detection slider 14 to float upward, which will then press against the pressure sensor 16 above it. The pressure sensor 16 sends a signal to the microcontroller 15, and the microcontroller 15 causes the signal transmission module 17 to transmit the information to the terminal equipment of the relevant department, alerting the inspection personnel that there is a problem with the drainage mechanism of the rainwater storage tank and that it is necessary to investigate and take countermeasures as soon as possible to prevent significant losses.

[0050] like Figure 6 As shown, the water level detection mechanism includes a float level gauge 11. A limit ring is connected to one side of the float level gauge 11. A limit rod is provided inside the limit ring. One end of the limit rod is connected to the inside of one of the central boxes 43, and the other end of the limit rod is connected to the bottom of the concrete top plate 7.

[0051] In this embodiment, a limiting rod is provided, with its upper end fixed to the bottom of the concrete top slab 7 and its lower end fixed to the bottom of the middle box 43 at the bottom layer. A float level gauge 11 is slidably connected to the rod, which is beneficial for the float level gauge 11 to work normally and prevents it from getting stuck inside a water storage box, causing a malfunction of the water level detection mechanism.

[0052] The working principle of this utility model embodiment is as follows: the bottom water storage module is laid on the reinforced concrete base slab 2 installed inside the foundation pit 1. The reinforced concrete base slab 2 is provided with positioning reinforcement grooves 45, and each water storage module has a corresponding positioning reinforcement column 44 at the bottom. This can quickly position the modules, speed up the construction, and strengthen the horizontal connection strength, connecting each layer together. Each water storage module has rounded corners on all four sides, resulting in a connecting cavity 6 at the connection point. Concrete is poured into the connecting cavity 6, thus connecting each layer of water storage modules together. The top layer is covered with a concrete top slab 7, forming a whole, which greatly enhances the anti-buoyancy ability and improves the construction efficiency.

[0053] In this embodiment of the utility model, an internal water level detection device is provided. However, traditional water level detection is generally set with a fixed range, and detections beyond the range are generally not referenced. Therefore, when the rainwater storage tank is in use, if the discharge mechanism malfunctions or is blocked, it may cause damage to the surrounding equipment of the entire rainwater storage tank, resulting in serious losses. Therefore, when water overflows, an alarm device is set at the connection between the inspection pipe 10 and the concrete top plate 7. Pressure is applied to the pressure sensor 16 through the float, and water overflow is detected. Then, the information is transmitted through the signal transmission module 17.

[0054] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
