Description

Technical Field

[0001] This utility model relates to the technical field of PP rainwater harvesting modules, and specifically discloses a PP component splicing device for rainwater harvesting. Background Technology

[0002] Rainwater harvesting refers to the collection and utilization of rainwater runoff collected from building rooftops and paved surfaces such as roads and plazas. This runoff is then collected, transported, purified, and stored through various channels. The rainwater is then used for greening, landscaping water features, washing, and replenishing groundwater sources, achieving the goal of comprehensive utilization of rainwater resources and water conservation. It has broad significance in mitigating urban flooding and groundwater level decline, controlling rainwater runoff pollution, and improving the urban ecological environment.

[0003] When assembling existing rainwater harvesting PP modules, the upper and lower collection cylinders lack a corresponding quick-connect structure, resulting in unstable connections and slow assembly speed, which in turn affects construction efficiency. Utility Model Content

[0004] This utility model proposes a PP component splicing device for rainwater harvesting. The locking ball is embedded in the slot of the connecting cylinder to form a mechanical self-locking mechanism, which realizes the rapid connection and shear-resistant fixation of the upper and lower modules. The push rod presses the locking ball through the limiting block, which can release the self-locking state and realize the rapid disassembly of the module, thereby effectively improving the construction efficiency of the entire rainwater harvesting module.

[0005] This utility model is implemented as follows: a PP component splicing device for rainwater harvesting, comprising:

[0006] The upper fixing plate and the lower fixing plate are provided with four mounting holes through their outer walls.

[0007] The collecting cylinder has a conical structure and is connected to the upper and lower fixing plates through mounting holes. Two collecting cylinders located on the same vertical axis are symmetrically connected. The outer wall of the smaller diameter end of the collecting cylinder has two symmetrically arranged ball grooves. The inside of each ball groove is movably connected to a retaining ball by a spring.

[0008] A connecting cylinder is disposed on the outer wall of two mating collection cylinders. Two slots are provided on the left and right sides of the inner wall of the connecting cylinder. Multiple push rods are movably connected through the outer wall of the connecting cylinder, and one end of each push rod extends into the interior of the multiple slots.

[0009] As a preferred embodiment of the PP component splicing device for rainwater collection according to this utility model, two positioning strips are fixedly connected to the outer wall of the smaller diameter end of the collection cylinder, and two positioning grooves matching the positioning strips are opened on the inner wall of the connecting cylinder, and the line connecting the two positioning strips is perpendicular to the line connecting the two ball grooves.

[0010] As a preferred embodiment of the PP component splicing device for rainwater harvesting according to this utility model, the push rod is fixedly connected to two symmetrically arranged limiting blocks at one end located inside the slot.

[0011] As a preferred embodiment of the PP component splicing device for rainwater collection according to this utility model, the outer wall of the end with the larger diameter of the collection cylinder is provided with an external thread, and the inner side of the mounting hole is provided with an internal thread that matches the external thread. The collection cylinder can be detachably connected through the cooperation of the external thread and the internal thread.

[0012] In a preferred embodiment of the PP component splicing device for rainwater harvesting according to this utility model, the diameters of the ball groove and the card groove are the same.

[0013] As a preferred embodiment of the PP component splicing device for rainwater harvesting according to this utility model, the other end of the push rod is fixedly connected to a push block.

[0014] As a preferred embodiment of the PP component splicing device for rainwater harvesting according to this utility model, two pins are fixedly connected to one side of the outer wall of the upper fixing plate and the lower fixing plate, and two insertion holes matching the pins are opened on the other side.

[0015] The beneficial effects of this utility model are:

[0016] When the upper and lower fixed plates are connected via the tapered collecting cylinder, the spring in the ball groove at the smaller end of the collecting cylinder pushes the retaining ball outward. The retaining ball embeds into the retaining groove of the connecting cylinder, forming a mechanical self-locking mechanism. This enables rapid connection and shear-resistant fixing of the upper and lower modules. When the collecting cylinder and connecting cylinder are sleeved together, the positioning groove on its inner wall mates perpendicularly with the positioning strip of the collecting cylinder, achieving rapid positioning and ensuring precise alignment of the splicing angle. The push rod presses the retaining ball through the limit block, releasing the self-locking state and enabling rapid disassembly of the module. The screw connection between the external thread of the collecting cylinder and the internal thread of the mounting hole enables rapid connection between the collecting cylinder and the upper and lower fixed plates, thereby effectively improving the construction efficiency of the entire rainwater collection module.

[0026] The upper fixing plate 1 and the lower fixing plate 2 are provided with four mounting holes 3 through the outer walls of both the upper fixing plate 1 and the lower fixing plate 2.

[0027] The collecting cylinder 4 has a conical structure and is connected to the upper fixing plate 1 and the lower fixing plate 2 through the mounting hole 3. The two collecting cylinders 4 located on the same vertical axis are symmetrically connected. The outer wall of the smaller diameter end of the collecting cylinder 4 has two symmetrically arranged ball grooves 6. The inside of the two ball grooves 6 is movably connected to the ball 7 by the spring 8.

[0028] The connecting cylinder 5 is located on the outer wall of the two docking collection cylinders 4. The inner wall of the connecting cylinder 5 has two slots 9 distributed vertically on both the left and right sides. Multiple push rods 10 are movably connected through the outer wall of the connecting cylinder 5, and one end of each push rod 10 extends into the interior of the multiple slots 9.

[0029] In this embodiment: when the upper fixing plate 1 and the lower fixing plate 2 are connected through the conical collecting cylinder 4, the spring 8 in the ball groove 6 at the smaller diameter end of the collecting cylinder 4 pushes the locking ball 7 outward. The locking ball 7 is embedded in the locking groove 9 of the connecting cylinder 5 to form a mechanical self-locking, realizing the rapid connection and shear-resistant fixing of the upper and lower modules. When the collecting cylinder 4 and the connecting cylinder 5 are sleeved, the positioning groove 12 on its inner wall is perpendicularly matched with the positioning strip 15 of the collecting cylinder 4 to achieve rapid positioning and ensure accurate alignment of the splicing angle. The push rod 10 presses the locking ball 7 through the limiting block 13, which can release the self-locking state and realize the rapid disassembly of the module. The screw connection between the external thread 14 of the collecting cylinder 4 and the internal thread of the mounting hole 3 realizes the rapid connection between the collecting cylinder 4 and the upper fixing plate 1 and the lower fixing plate 2, thereby effectively improving the construction efficiency of the entire rainwater collection module.

[0030] As a technical optimization of this utility model, two positioning strips 15 are fixedly connected to the outer wall of the smaller diameter end of the collecting cylinder 4, and two positioning grooves 12 that match the positioning strips 15 are opened on the inner wall of the connecting cylinder 5. The line connecting the two positioning strips 15 is perpendicular to the line connecting the two ball grooves 6.

[0031] In this embodiment: when the collecting cylinder 4 and the connecting cylinder 5 are sleeved together, the positioning groove 12 on its inner wall is perpendicularly engaged with the positioning strip 15 of the collecting cylinder 4 to achieve rapid positioning and ensure accurate alignment of the splicing angle.

[0032] As a technical optimization of this utility model, the push rod 10 is fixedly connected to two symmetrically arranged limiting blocks 13 at one end located inside the slot 9.

[0033] In this embodiment, two symmetrically arranged limiting blocks 13 are fixedly connected to one end of the push rod 10 located inside the slot 9 to prevent the push rod 10 from detaching from the connecting cylinder 5.

[0034] As a technical optimization of this utility model, the outer wall of the larger diameter end of the collecting cylinder 4 is provided with an external thread 14, and the inner side of the mounting hole 3 is provided with an internal thread that matches the external thread 14. The collecting cylinder 4 can be detachably connected through the cooperation of the external thread 14 and the internal thread.

[0035] In this embodiment, the external thread 14 of the collecting cylinder 4 is screwed into the internal thread of the mounting hole 3 to achieve a quick connection between the collecting cylinder 4 and the upper fixing plate 1 and the lower fixing plate 2.

[0036] As a technical optimization of this utility model, the diameters of the ball groove 6 and the card groove 9 are the same.

[0037] In this embodiment: the ball groove 6 and the card slot 9 have the same diameter. After the collecting tube 4 is inserted into the connecting tube 5, the ball groove 6 and the card slot 9 are aligned, which makes it easy for the card ball 7 to enter the card slot 9 to form a snap-fit.

[0038] As a technical optimization of this utility model, the other end of the push rod 10 is fixedly connected to the push block 11.

[0039] In this embodiment, a push block 11 is fixedly connected to the other end of the push rod 10, which facilitates pushing and pulling the push rod 10.

[0040] As a technical optimization of this utility model, two pins are fixedly connected to one side of the outer wall of the upper fixing plate 1 and the lower fixing plate 2, and two insertion holes matching the pins are opened on the other side.

[0041] In this embodiment, the use of pins and holes facilitates the quick assembly of adjacent upper fixing plates 1 and lower fixing plates 2.

[0042] The working principle and usage process of this utility model are as follows: In use, the lower fixing plate 2 is placed horizontally, and multiple collecting cylinders 4 are screwed into the mounting holes 3 of the lower fixing plate 2 through external threads 14. The upper fixing plate 1 is then inverted, and multiple collecting cylinders 4 are screwed into the mounting holes 3 of the upper fixing plate 1 through external threads 14. Subsequently, multiple connecting cylinders 5 are sleeved onto the outer walls of the multiple collecting cylinders 4 located on the lower fixing plate 2. Further, the multiple collecting cylinders 4 on the upper fixing plate 1 are sleeved onto the other ends of the multiple connecting cylinders 5, completing the splicing of multiple collecting cylinders 4 on both the upper and lower sides. When the upper fixing plate... When plate 1 and lower fixed plate 2 are connected through conical collecting cylinder 4, spring 8 in ball groove 6 at the smaller end of collecting cylinder 4 pushes ball 7 outward. Ball 7 is embedded in slot 9 of connecting cylinder 5 to form mechanical self-locking, realizing quick connection and shear-resistant fixing of upper and lower modules. When collecting cylinder 4 and connecting cylinder 5 are sleeved, positioning groove 12 on its inner wall is perpendicular to positioning strip 15 of collecting cylinder 4 to achieve quick positioning and ensure accurate alignment of splicing angle. Push rod 10 presses ball 7 through limit block 13 to release self-locking state and realize quick disassembly of module.
