[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Combine the following Figures 1 to 7 , describing an embodiment of the present invention.

[0031] like Figure 1 As shown, according to an embodiment of the invention, a rainwater collection and reuse device is provided, including: a guide box 2 with an open opening; a filter screen 3, arranged in the guide box 2, the filter screen 3 is slidably connected to the guide box 2 in a first direction, and the first direction is the extension direction of the filter screen 3; an anti-blocking mechanism 4, connected to the filter screen 3, the anti-blocking mechanism 4 is suitable for driving the filter screen 3 to reciprocate linearly in the first direction.

[0032] In this embodiment, the rainwater collection and reuse device comprises a guide box 2, a filter screen 3 and an anti-blocking mechanism 4. An opening is provided on the top of the guide box 2 for receiving rainwater drained from the roof or other collection areas. The opening is in the shape of a guide box 2, which is convenient for collecting rainwater. Rainwater enters the guide box 2 through the opening accompanied by leaves, branches or other impurities, wherein the filter screen 3 is used for preliminary filtering of the rainwater entering the guide box 2. The layout direction of the filter screen 3 is defined as a first direction, and the connection between the filter screen 3 and the guide box 2 is a sliding connection. This design enables the filter screen 3 to slide freely in the first direction, thereby realizing flexible adjustment of the position. When rainwater flows through the filter screen 3, larger impurities such as leaves, dust, etc. are intercepted on the surface of the filter screen 3, and the filtered rainwater can smoothly flow into the lower part of the guide box 2, ready for further processing or storage.

[0033] In order to ensure that the filter 3 can play a filtering role stably for a long time, an anti-blocking mechanism 4 is provided. The anti-blocking mechanism 4 is connected to the filter 3, and can drive the filter 3 to perform reciprocating linear motion in the first direction. This mode of movement is similar to the action of "sweeping" the surface of the filter 3. By regularly moving the filter 3, it is possible to effectively prevent the accumulation of impurities and avoid the filter 3 from being blocked and causing the filtering efficiency to decrease. The driving mode of the anti-blocking mechanism 4 can be mechanical, for example, reciprocating motion is achieved through mechanical structures such as springs 405 and cams; or it can be electric, using a motor to drive the filter 3 to move regularly. Regardless of the driving mode adopted, the anti-blocking mechanism 4 can ensure that the filter 3 always maintains reciprocating linear motion in the extension direction of the first direction.

[0034] The inner wall of the guide box 2 is formed with a groove for inserting the filter 3, and the arrangement of the groove provides space for the reciprocating movement of the filter 3 in the first direction.

[0035] The entire rainwater collection and reuse device realizes the functions of efficient rainwater collection, filtration and anti-clogging through the coordinated work of the guide box 2, the filter net 3 and the anti-clogging mechanism 4. It can not only effectively utilize rainwater resources to reduce dependence on traditional water resources, but also reduce the burden on the urban drainage system to a certain extent, and has significant environmental and economic benefits.

[0036] The guide box 2 is a rectangular box, and the filter 3 is a rectangular sheet net, which matches the internal structure of the guide box 2, so that the filter 3 can be tightly installed inside the guide box 2 to cover the entire rainwater inflow path. The rectangular sheet structure of the filter 3 is also convenient for installation and replacement. Maintenance personnel can easily remove it from the guide box 2 for cleaning or replacement, thereby ensuring the continuous and efficient operation of the device.

[0037] Furthermore, if Figure 2As shown, the anti-blocking mechanism 4 includes: a driving mechanism 401, having a driving end, the driving end can reciprocate along the second direction, and the second direction is set at an angle with the first direction; a transmission mechanism, which is arranged at the driving end, and the transmission mechanism is connected to the filter screen 3, and when the transmission mechanism reciprocates in the second direction with the driving mechanism 401, the filter screen 3 is driven to reciprocate in the first direction.

[0038] In this embodiment, the driving end of the driving mechanism 401 can reciprocate in the second direction. The second direction and the sliding direction of the filter screen 3, that is, the first direction, are set at a certain angle, for example, they can be perpendicular to each other, so as to convert the reciprocating motion in the second direction into the reciprocating motion in the first direction, which can make the overall structure more compact. The movement mode of the driving mechanism 401 can be mechanical, for example, reciprocating motion is achieved through a spring 405, a cam or a crank connecting rod mechanism; it can also be electric, using the rotational motion of the motor and converting it into linear reciprocating motion through a transmission device such as gears and belts.

[0039] The transmission mechanism is used to connect the driving mechanism 401 and the filter 3, and its function is to convert the reciprocating motion of the driving mechanism 401 in the second direction into the reciprocating motion of the filter 3 in the first direction. The transmission mechanism can use a mechanical structure such as a connecting rod, a slider or a gear rack to convert and transmit the motion direction of the driving end. When the driving end reciprocates in the second direction, the transmission mechanism will move accordingly, and through its connection relationship with the filter 3, drive the filter 3 to perform corresponding reciprocating linear motion in the first direction.

[0040] Through the cooperation of the driving mechanism 401, the transmission mechanism and the filter screen 3, the filter screen 3 can be regularly moved in the first direction, thereby effectively preventing impurities from accumulating on the surface of the filter screen 3 and avoiding the filter screen 3 from being clogged and reducing the filtering efficiency.

[0041] The driving mechanism 401 is a servo driving module assembled on the guide box 2 and a connecting rod 402 arranged at the output end of the servo driving module, and the slide 403 is arranged at one end of the connecting rod 402 away from the servo driving module.

[0042] Furthermore, continue to combine Figure 2 As shown, the transmission mechanism includes: an elastic member having a first end and a second end in the elastic direction, one end of which abuts against the guide box 2; a sliding member arranged at the second end; a slide 403 having a guide surface, the guide surface is inclined, and the guide surface abuts against the sliding member.

[0043] In this embodiment, the transmission mechanism mainly includes an elastic member, a sliding member and a slide 403, which together complete the transmission of power and the conversion of the movement direction.

[0044] The slide 403 guides the movement direction of the slide member through the inclined guide surface, and converts the reciprocating motion of the drive mechanism 401 into the linear reciprocating motion of the filter 3. The inclination angle of the guide surface is closely related to the angle between the movement direction of the drive mechanism 401 and the movement direction of the filter 3. When the slide 403 moves in the second direction, the inclined guide surface of the slide 403 will decompose the movement direction of the slide member into two components: one is consistent with the movement direction of the slide 403, and the other is consistent with the movement direction of the filter 3. Therefore, the slide 403 can efficiently convert the reciprocating motion of the drive mechanism 401 into the linear reciprocating motion of the filter 3 in the first direction.

[0045] The elastic member is used to achieve the buffering and resetting of the movement. The elastic member has two ends in the elastic direction: a first end and a second end. The first end abuts against the side wall of the guide box 2, plays a role of fixing and supporting, and provides a stable reference point for the elastic member. The elastic direction of the elastic member is consistent with the movement direction of the filter 3, that is, the first direction, and the strength and rhythm of the movement are adjusted by elastic deformation.

[0046] The sliding member may be a pulley 407, which can reduce friction and wear during movement.

[0047] Furthermore, if Figure 3 As shown, the slide 403 is provided with a guide groove 408, which forms a guide surface, which plays a role of limiting and guiding the operation of the slide, so that the movement of the filter screen 3 is more stable. The longitudinal section of the slide 403 is a right triangle.

[0048] During the operation of the anti-blocking mechanism 4, the driving end of the driving mechanism 401 reciprocates along the second direction. When the driving end moves, the elastic member is compressed or stretched through the connection relationship of the transmission mechanism, generating an elastic force. The sliding member slides along the guide surface of the slide 403 under the action of the elastic force. Due to the inclined setting of the guide surface, the movement direction of the sliding member is decomposed into two components, of which the component consistent with the movement direction of the filter screen 3 is transmitted to the filter screen 3 through the transmission mechanism, thereby driving the filter screen 3 to reciprocate in the first direction. This mode of movement can not only effectively prevent the filter screen 3 from being blocked, but also reduce the impact and wear during the movement through the buffering effect of the elastic member, thereby improving the service life and operation stability of the transmission mechanism.

[0049] More specifically, the elastic member includes a spring 405, a rod body and a connecting seat 406. The side wall of the guide box 2 is provided with a through hole for the rod body to pass through. One end of the rod body is connected to the filter screen 3, and the other end of the rod body is provided with a connecting seat 406. The connecting seat 406 is provided with a sliding member. The spring 405 is sleeved on the rod body, and one end of the spring 405 abuts against the side wall of the guide box 2, and the other end of the spring 405 is provided on the connecting seat 406.

[0050] The driving mechanism 401 and the transmission mechanism are both arranged outside the flow guide box 2. The side wall of the flow guide box 2 is provided with a perforation, and a sealing seat 404 is provided at the perforation for the transmission mechanism to pass through and connect with the filter screen 3. The sealing seat 404 is provided with a receiving groove matched with the filter screen 3 on the side facing the filter screen 3. The sealing seat 404 is made of rubber, which plays a role in improving the sealing performance of the connection between the filter screen 3 and the flow guide box 2.

[0051] Further, continue to combine Figure 2 As shown, the rainwater collection and reuse device also includes a limiting mechanism, which is slidably connected to the transmission mechanism, and plays a role in accurately limiting and controlling the movement range of the transmission mechanism, thereby ensuring the smooth operation of the entire device.

[0052] Specifically, the limiting mechanism includes a limiting rod 409 and a sliding sleeve. One end of the limiting rod 409 is connected to the guide box 2. The limiting sliding sleeve 410 is arranged on the slide 403, and the limiting sliding sleeve 410 is sleeved on the outside of the limiting rod 409. The end of the limiting rod 409 away from the guide box 2 is connected to the rainwater recycling box 1. The limiting sliding sleeve 410 is formed with a limiting hole that is clearance-matched with the limiting rod 409. When the slide 403 moves up and down, the limiting sliding sleeve 410 is driven to move synchronously. At this time, the limiting sliding sleeve 410 slides on the outer surface of the limiting rod 409, thereby limiting and guiding the movement of the slide 403.

[0053] Furthermore, the flow guide box 2 has a water outlet, such as Figure 4 and Figure 5 As shown, the rainwater collection and reuse device also includes: a rainwater recovery box 1, which is connected to the water outlet; and a filtering mechanism, which is provided with a layered structure in the flow direction of the water flow to filter the incoming rainwater.

[0054] In this embodiment, the rainwater recovery box 1 is arranged below the guide box 2. During the operation of the rainwater collection and reuse device, rainwater first enters the guide box 2 through the opening of the guide box 2, and after being filtered by the preliminary filter 3, flows out from the water outlet of the guide box 2, and then flows into the rainwater recovery box 1. In the rainwater recovery box 1, rainwater will pass through the layered structure of the filtering mechanism, undergo deep purification by multiple layers of filtering materials, and finally meet the standards for reuse.

[0055] More specifically, Figure 5 and Figure 6 As shown, the filtering mechanism includes: a polypropylene fiber board 414, which is arranged toward the water outlet; a ceramic board 416, which is arranged toward the polypropylene fiber board 414; and an activated carbon board 415, which is arranged between the polypropylene fiber board 414 and the ceramic board 416.

[0056] In this embodiment, rainwater first passes through the polypropylene fiber board 414 to remove large particles of impurities and suspended solids therein, effectively reducing the burden on the subsequent filter layer and ensuring that large particles of impurities in the water flow will not block the activated carbon board 415 and the ceramic board 416. The rainwater that has passed the primary filtration flows into the activated carbon board 415, which absorbs organic matter, odor, pigments and chemical pollutants in the water through its microporous structure, further improving the water quality. The adsorption effect of the activated carbon board 415 not only improves the chemical properties of the rainwater, but also improves its sensory quality. Finally, the rainwater adsorbed by the activated carbon passes through the ceramic board 416, which removes fine particles and microorganisms in the water with its high-precision pore structure, ensuring that the purified rainwater meets the standards for reuse. The design of this multi-layer filtration structure allows each layer of filtration material to give full play to its advantages and cooperate with each other to achieve an efficient purification effect.

[0057] Specifically, the polypropylene fiber board 414 is arranged toward the water outlet of the guide box 2, and is the first line of defense after the rainwater enters the filtering mechanism, and can effectively intercept large particles of impurities in the rainwater, such as sand, leaf fragments, dust, etc. This interception effect not only reduces the burden on the subsequent filtering layer, but also prevents large particles of impurities from clogging the activated carbon board 415 and the ceramic board 416.

[0058] The activated carbon plate 415 is located between the polypropylene fiber plate 414 and the ceramic plate 416, so that the activated carbon plate 415 can play its powerful adsorption role in the water after primary filtration, and at the same time provide further purification guarantee for the ceramic plate 416. Among them, the activated carbon has an extremely high specific surface area and rich microporous structure, which can effectively adsorb organic matter, odor, pigments and some heavy metal ions in the water. These microporous structures provide a large number of adsorption sites for pollutants, which can significantly improve the water quality of rainwater. The activated carbon plate 415 can not only remove chemical pollutants in the water, but also adsorb some microbial metabolites to further improve the purity of the water quality. Its adsorption effect is particularly effective for soluble organic matter and odor components in rainwater, which can significantly improve the quality of purified rainwater. In addition, the activated carbon can restore its adsorption capacity through thermal desorption or other regeneration methods, reducing the cost of use.

[0059] The pore size of the ceramic plate 416 is very small, usually at the micron level, which can effectively remove fine suspended particles, bacteria and some viruses in the water. Ceramic materials have good antibacterial properties and can inhibit the growth and reproduction of microorganisms, further improving the safety of water quality. The main function of the ceramic plate 416 is to act as a terminal filtration layer to remove tiny particles and microorganisms in the water, ensuring that the purified rainwater reaches a high degree of cleanliness and safety.

[0060] A baffle is provided in the rainwater recovery box 1, and the polypropylene fiber board 414, the activated carbon board 415 and the ceramic board 416 are all placed on the baffle. The baffle is symmetrically arranged in the present application to limit the polypropylene fiber board 414, the activated carbon board 415 and the ceramic board 416.

[0061] Furthermore, if Figure 7 As shown, the rainwater collection and reuse device also includes: a liquid level sensor 412, which is arranged in the rainwater recovery box 1; a conveying module 413, which is arranged in the rainwater recovery box 1; and a control module 411, which is arranged outside the rainwater recovery box 1. The control module 411 is communicatively connected with the liquid level sensor 412 and the conveying module 413 respectively, so that the control module 411 controls the conveying module 413 to convey the treated rainwater according to the signal of the liquid level sensor 412.

[0062] In this embodiment, the input end of the delivery module 413 is provided with a first connecting pipe whose other end is connected to the rainwater recycling tank 1, and the output end of the delivery module 413 is provided with a second connecting pipe. The control module 411 is signal-connected to the delivery module 413, and the control module 411 is electrically connected to the delivery module 413.

[0063] It should be noted that the transport module 413 includes but is not limited to a centrifugal pump or a booster pump or other equipment or structure that can enable rainwater in the rainwater recycling box 1 to leave the rainwater recycling box 1. Preferably, the transport module 413 in this application is a centrifugal pump.

[0064] In summary, the working principle of the rainwater collection and reuse device provided by the present invention is:

[0065] When the rainwater collecting and recycling device is used, when it rains, rainwater from the outside will flow into the guide box 2, and leaves, branches or other impurities in the rainwater will be filtered by the filter net 3, and then will accumulate on the filter net 3. At this time, the driving mechanism 401 is started, and the driving mechanism 401 drives the connecting rod 402 and the slide 403 to make up and down reciprocating motions. When the slide 403 moves downward, the sliding member 407 is forced to drive the connecting seat 406 and the filter net 3 to move to the right. At this time, the spring 405 is compressed. When the slide 403 moves upward, the spring 405 rebounds, and the sliding member 407 drives the connecting seat 406 and the filter net 3 to move to the left. As the slide 403 makes up and down reciprocating motions, the filter net 3 makes left and right reciprocating motions in the guide box 2, so that leaves, branches or other impurities are always in motion, and thus leaves, branches or other impurities will not block the filter net 3, thereby ensuring the water discharge of the rainwater collecting and recycling device and avoiding rainwater overflow.

[0066] After the rainwater passes through the filter 3 and enters the rainwater recovery tank 1, the polypropylene fiber board 414 can effectively intercept the suspended matter, colloid and small particle impurities in the rainwater, and play a preliminary purification role for the rainwater. After the rainwater passes through the polypropylene fiber board 414, the activated carbon board 415 filters the rainwater again, which can absorb the color and odor in the rainwater and volatilize the organic matter in the rainwater. After the rainwater passes through the activated carbon board 415, it reaches the ceramic board 416, which can perform antibacterial and activation treatment on the rainwater, filter out the soluble heavy metal ions, harmful residual chlorine and suspended pollutants in the rainwater, and make the rainwater in the rainwater recovery tank 1 be multi-filtered. When the rainwater level in the rainwater recovery tank 1 exceeds the set value of the liquid level sensor 412, the liquid level sensor 412 sends a signal to the control module 411, and the control module 411 starts the conveying module 413 after receiving the signal. After the conveying module 413 is started, the rainwater in the rainwater recovery tank 1 is conveyed to the place where water is needed through the first connecting pipe and the second connecting pipe.

[0067] Obviously, the above embodiments are merely examples for clear description and are not limitations of the implementation methods.

[0068] For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, the obvious changes or modifications derived from this are still within the protection scope of the invention.
