Description

Technical Field

[0001] This application belongs to the field of rainwater harvesting technology, and specifically relates to a rainwater harvesting device. Background Technology

[0002] Initial rainwater refers to rainwater produced at the beginning of a rainfall event. Because initial rainwater dissolves pollutants in the air, it needs to be collected separately from later rainwater. This is especially true in densely populated areas such as school buildings, where initial rainwater forms runoff after hitting the ground. Since the ground contains a large amount of pollutants, this further contaminates the initial rainwater, increasing the necessity for separate collection.

[0003] In existing technologies, initial rainwater and subsequent rainwater are stored separately in two independent cavities within the container. However, for a single rainfall event, the ratio of initial rainwater to subsequent rainwater varies depending on factors such as precipitation efficiency and the degree of ground pollution. Therefore, in most cases, part of the space in one of the cavities will be idle, reducing the device's capacity to hold rainwater. Utility Model Content

[0015] A linear cylinder is disposed on the upper side of the tank body, and its power output axis is perpendicular to the axis of the gear ring. The power output end of the linear cylinder is connected to a rack that meshes with the gear ring.

[0016] The protruding part of the docking rod is inserted into the mounting hole so that when the transmission arm swings, the movable baffle moves around the main shaft.

[0017] In one possible implementation, the traffic splitting component includes:

The first water outlet pipe and the second water outlet pipe are respectively connected to the first chamber and the second chamber to discharge rainwater into the first chamber or the second chamber.

[0021] In one possible implementation, the inner diameter of the upper end of the water inlet pipe gradually increases from bottom to top to form a funnel-shaped structure.

[0022] In one possible implementation, the bottom of the tank is provided with a first drain pipe and a second drain pipe, which are respectively connected to the first chamber and the second chamber, and both the first drain pipe and the second drain pipe are connected to a valve body.

[0023] In one possible implementation, the outer wall of the spindle is provided with an arc-shaped groove extending circumferentially therein, and the movable baffle has a protrusion embedded in the arc-shaped groove.

[0024] In one possible implementation, the tank includes:

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0050] Please refer to the following: Figures 1 to 10 The rainwater harvesting device provided in this application will now be described. The rainwater harvesting device proposed in this application includes a tank 1, a main shaft 2, a fixed baffle 3, and a movable baffle 4.

[0051] The tank 1 has a hollow interior to form a water storage chamber 111, which is used to hold initial rainwater and subsequent rainwater to make full use of rainwater resources.

[0052] The main shaft 2 is coaxially arranged inside the water storage chamber 111, and its upper and lower ends abut against the top and bottom surfaces of the water storage chamber 111, respectively.

[0053] The fixed baffle 3 is fixedly installed between the main shaft 2 and the inner wall of the water storage chamber 111. Specifically, the fixed baffle 3 is fixedly connected to the outer wall of the main shaft 2, and its upper and lower ends are respectively aligned with the upper and lower ends of the main shaft 2. The fixed baffle 3 extends outward along the radial direction of the main shaft 2 to connect with the inner wall of the water storage chamber 111.

[0054] A movable baffle 4 is disposed within the water storage chamber 111. Specifically, the movable baffle 4 and the fixed baffle 3 are arranged at intervals along the circumference of the main shaft 2. The upper and lower ends of the movable baffle 4 are also aligned with the upper and lower ends of the main shaft 2, and the sides facing away from the main shaft 2 are connected to the main shaft 2 and the inner wall of the water storage chamber 111, respectively. Based on this, the fixed baffle 3 and the movable baffle 4 can divide the water storage chamber 111 into a first chamber and a second chamber. In this embodiment, the movable baffle 4 has the degree of freedom to move around the main shaft 2. When the movable baffle 4 moves, the capacity of one of the first chamber and the second chamber decreases, and the capacity of the other increases, that is, the capacity ratio of the first chamber and the second chamber changes.

[0055] In order to lock the capacity ratio of the first chamber and the second chamber, there is an adjustment structure 5 between the movable baffle 4 and the tank body 1; the movable baffle 4 and the tank body 1 can be connected through the adjustment structure 5 to achieve the technical purpose of fixing the movable baffle 4 relative to the tank body 1.

[0056] The tank body 1 also includes a diversion assembly 6, which is connected to the first chamber and the second chamber, and is used to allow rainwater to be discharged into the first chamber or the second chamber.

[0057] In this embodiment, both the fixed baffle 3 and the movable baffle 4 can fill the space between the main shaft 2 and the inner wall of the water storage chamber 111 to separate the water storage chamber 111 into a first chamber and a second chamber. The position of the movable baffle 4 can be changed and fixed by adjusting the structure 5 so that the volume ratio of the first chamber and the second chamber can be changed and fixed, thereby adapting to the containment of initial rainwater and later rainwater under different ratio conditions.

[0058] In the early stages of rainfall, rainwater enters the first chamber (or the second chamber) from the diversion component 6 to store the initial rainwater. After the initial rainwater is stored, rainwater can enter the second chamber (or the first chamber) from the diversion component 6 to store the later rainwater.

[0059] Compared with the prior art, the rainwater collection device provided in this embodiment can change the position of the movable baffle 4 by adjusting the structure 5, thereby adjusting the size ratio of the first chamber and the second chamber, so as to adapt to the initial rainwater and the later rainwater under different ratio conditions, and complete the adjustment of the storage space for the two types of rainwater, thereby ensuring that the rainwater capacity meets the requirements and improving the stability of the device in actual use.

[0060] In some embodiments, such as Figure 4 , Figure 6 and Figure 8 As shown, the upper side of the tank body 1 is provided with a guide hole 121 that communicates with the water storage chamber 111. This guide hole 121 extends along the circumference of the tank body 1. Based on this, the movable baffle 4 also includes a docking rod 41, which is disposed on the movable baffle 4 and is inserted into the guide hole 121 and extends out to limit the movement trajectory of the movable baffle 4.

[0061] It should be further explained that in this embodiment, there are multiple guide holes 121, which are arranged at radial intervals along the tank body 1, and there are also multiple corresponding docking rods 41, which are inserted into the guide holes 121 one by one.

[0062] In some embodiments, such as Figure 4 and Figure 9 As shown, the adjustment structure 5 includes a transmission arm 51 and a linear cylinder 52.

[0063] The transmission arm 51 is located on the upper side of the tank body 1, with one end rotatably connected to the center of the upper side of the tank body 1 in the vertical direction, and the other end extending outward along the radial direction of the tank body 1.

[0064] The transmission arm 51 has a mounting hole 511 that runs through the vertical direction, and a toothed ring 512 is fitted at the connection between the transmission arm 51 and the tank body 1. The toothed ring 512 is coaxially arranged with the rotation axis of the transmission arm 51. Specifically, the toothed ring 512 has a notch that runs through its radial direction. The end of the transmission arm 51 is fitted into this notch and fixedly connected to the toothed ring 512, usually by welding.

[0065] The linear cylinder 52 is located on the upper side of the tank body 1. Its power output axis is perpendicular to the axis of the gear ring 512, and the power output end of the linear cylinder 52 is connected to a rack 521 that meshes with the gear ring 512.

[0066] By adopting the above technical solution, when the linear cylinder 52 is started, the rack 521 moves along a preset trajectory, causing the gear ring 512 to rotate, thereby driving the transmission arm 51 to swing. On this basis, the protruding part of the aforementioned docking rod 41 is inserted into the mounting hole 511, so that when the transmission arm 51 swings, the movable baffle 4 moves synchronously around the main shaft 2.

[0067] In some embodiments, such as Figure 1 and Figure 3 As shown, the diversion assembly 6 includes an inlet pipe 61 and a three-way valve 62.

[0068] The upper end of the inlet pipe 61 is used for rainwater drainage. This can be achieved by connecting the inlet end of the inlet pipe 61 to the rainwater conduit, or by leaving the upper end of the inlet pipe 61 open and directing ground rainwater above the inlet pipe 61.

[0069] The three-way valve 62 is connected to the lower end of the inlet pipe 61, and the three-way valve 62 has a first outlet end and a second outlet end; based on this, the first outlet end and the second outlet end are respectively connected to the first outlet pipe 621 and the second outlet pipe 622.

[0070] In actual use, the first water outlet pipe 621 and the second water outlet pipe 622 are connected to the first chamber and the second chamber respectively to discharge rainwater into the first chamber or the second chamber; by adjusting the three-way valve 62, the rainwater discharged by the inlet pipe 61 can be input into the first chamber or the second chamber.

[0071] In some embodiments, such as Figure 1 and Figure 2 As shown, the inner diameter of the upper end of the inlet pipe 61 gradually increases from bottom to top to form a funnel-shaped structure, which facilitates the flow of rainwater and improves the efficiency of rainwater flow.

[0072] In some embodiments, such as Figure 1 and Figure 3 As shown, the bottom of the tank body 1 is provided with a first drain pipe 112 and a second drain pipe 113. The first drain pipe 112 and the second drain pipe 113 are respectively connected to the first chamber and the second chamber, and a valve body 7 is connected to both the first drain pipe 112 and the second drain pipe 113.

[0073] In actual use, by opening the valve body 7, the corresponding first drain pipe 112 or second drain pipe 113 can be opened, thereby discharging the liquid stored in the corresponding first or second chamber for the purification of initial rainwater or the utilization of subsequent rainwater.

[0074] In some embodiments, such as Figure 4 , Figure 7 and Figure 8 As shown, an arc-shaped groove 21 extending circumferentially is provided on the outer wall of the main shaft 2, and a protrusion 42 is embedded in the arc-shaped groove 21 on the movable baffle 4; in this embodiment, the protrusion 42 can fill the arc-shaped groove 21 to avoid the formation of gaps.

[0075] By adopting the above technical solution, the combined structure of the protrusion 42 and the arc groove 21 can prevent the movable baffle 4 from tilting relative to the main shaft 2, thereby improving the structural stability of the device.

[0076] In some embodiments, such as Figures 3 to 7 As shown, the tank body 1 includes a bottom tank 11 and a top cover 12.

[0077] The bottom tank 11 has a hollow interior and an open top.

[0078] The top cover 12 is located on the upper side of the bottom tank 11 and is detachably connected to the bottom tank 11.

[0079] When the top cover 12 is connected to the bottom tank 11, the top cover 12 can seal the interior of the bottom tank 11, thereby forming the aforementioned water storage chamber 111.

[0080] The aforementioned main shaft 2 is coaxially arranged inside the bottom tank 11 and is adapted to abut against the bottom surface of the top cover 12, so that both the fixed baffle 3 and the movable baffle 4 abut against the inner bottom surface of the top cover 12 and the bottom tank 11.

[0081] In some embodiments, such as Figure 5 As shown, the bottom tank 11 has a lower mounting plate 9 extending radially outward at its upper end, and the top cover 12 has an upper mounting plate 8 extending radially outward on its upper end; when the bottom tank 11 and the top cover 12 are joined, the lower mounting plate 9 and the upper mounting plate 8 abut against each other.

[0082] The upper mounting plate 8 has fixing screws 81 spaced apart along its circumference, each fixing screw 81 extending downwards; the lower mounting plate 9 has multiple positioning holes 91 spaced apart along its circumference, each positioning hole 91 penetrating in the vertical direction, so that the multiple fixing screws 81 are inserted into the multiple positioning holes 91 one by one and protrude.

[0083] Each fixing screw 81 has a threaded locking nut 82 on its protruding part. The locking nut 82 is adapted to abut against the lower side of the lower mounting plate 9 to restrict the separation of the bottom tank 11 and the top cover 12, thereby realizing the detachable connection between the bottom tank 11 and the top cover 12.

[0084] In some embodiments, such as Figure 1 , Figure 3 and Figure 10 As shown, the top of the tank 1 is covered with a protective shell 10. The inner circumferential surface of the protective shell 10 has a raised ring made of elastic material. The top of the tank 1 has a groove that fits the raised ring so that when the protective shell 10 is placed on the top of the tank 1, the raised ring is embedded in the groove, preventing the tank 1 and the protective shell 10 from separating unexpectedly.

[0085] By adopting the above technical solution, the protective shell 10 serves to prevent the inner items from being affected by rainwater, dust and other impurities; in this embodiment, the inner items include the transmission arm 51 and the linear cylinder 52, etc.

[0086] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
