Building rainfall drainage anti-blocking structure

Abstract

The utility model relates to a building rainfall drainage anti-blocking structure which can solve the problem that a longitudinal filter screen of an existing drainage channel is blocked due to the fact that impurities are accumulated easily. A positioning shaft is arranged in a channel body, the side end of the positioning shaft is connected with a plurality of supporting rods, and limiting rods are fixed to the lower ends of the supporting rods. The plurality of mounting frames are sleeved outside the limiting rods, and the longitudinal filter screens are embedded into the mounting frames. The mounting frame rotates along with the positioning shaft to adjust the position of the longitudinal filter screen to prevent impurity accumulation. A special limiting piece is further arranged in the device, the vertical projection of the special limiting piece is trapezoidal, and the horizontal projection of the special limiting piece is arc-shaped, so that the height of the mounting frame is changed when the mounting frame moves. When the mounting frame rotates to the upper side of the limiting piece, the enriched impurities can enter the storage groove of the limiting piece due to loss of support and reduction of the depth of the water body, so that effective separation of the impurities and the water body is realized, and the drainage anti-blocking performance is improved.

Description

Technical Field

[0001] This utility model relates to the field of anti-blocking mechanism technology, and in particular to an anti-blocking structure for building rainwater drainage. Background Technology

[0002] In building stormwater drainage systems, preventing blockages is a crucial issue. Existing building stormwater drainage systems typically include channels to carry and divert water. The vertical sections of these channels are generally designed with a U-shape, which effectively diverts water and ensures the basic function of drainage.

[0003] To prevent impurities in the water from causing blockages, existing technologies typically install longitudinal filters inside the channel, specifically within the U-shaped opening. The main function of the longitudinal filter is to divide the water, ensuring that the water flow can pass smoothly through the filter holes, while effectively intercepting and blocking impurities in the water, thereby preventing direct blockage of the drainage channel.

[0004] However, this design in the existing technology has obvious drawbacks. Because the position of the longitudinal filter is fixed, impurities will inevitably accumulate near the longitudinal filter during long-term use. Over time, these accumulated impurities will increase, gradually forming new sources of blockage. Once the longitudinal filter is blocked, the flow of water will be obstructed, drainage efficiency will be significantly reduced, and in severe cases, it may even lead to the paralysis of the drainage system, causing a series of problems such as water accumulation, bringing many inconveniences and safety hazards to the normal use of the building and the surrounding environment.

[0005] Therefore, we need a new building rainwater drainage anti-clogging structure to solve the problem of easy clogging of existing longitudinal filters. Utility Model Content

[0006] To address the common problems of impurity clogging and high maintenance costs in existing technologies, this invention proposes a building rainwater drainage anti-clogging structure. This structure utilizes an innovative design to effectively prevent impurity accumulation, solving the problem in existing technologies where the fixed position of the longitudinal filter screen leads to easy accumulation of impurities near the screen during long-term use.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A building rainwater drainage anti-clogging structure includes a channel body with a longitudinal filter screen inside. It also includes a vertically axial positioning shaft, with multiple horizontally oriented support rods fixedly connected to the side of the positioning shaft. These support rods are equidistantly arranged around the central axis of the positioning shaft. Each support rod has a vertically axially oriented limiting rod fixedly connected to its lower side, and each limiting rod is fitted with an installation frame. Multiple longitudinal filters are provided, each corresponding to one of the installation frames, and each longitudinal filter is embedded within its corresponding installation frame and fixedly connected. A limiting member fixedly connected to the channel body is provided on one side of the positioning shaft. The limiting member's vertical projection is trapezoidal, and its horizontal projection is arc-shaped. A receiving groove is provided on the limiting member, inside which a transverse filter screen is provided. The diameter of the filter holes in the transverse filter screen is larger than that of the longitudinal filter screen. A storage groove is provided on the lower side of the transverse filter screen.

[0009] Preferably, a longitudinal baffle is provided inside the channel body. One end of the longitudinal baffle is fixedly connected to the channel body, while the other end of the longitudinal baffle forms a water outlet with the inner wall of the channel body, and the water outlet faces the limiting member.

[0010] Preferably, the end of the longitudinal baffle away from the inner wall of the channel is located on the side of the positioning shaft near the limiting member, and the center line of the longitudinal baffle is parallel to the tangential direction of the limiting member.

[0011] Preferably, the mounting frame has multiple through holes I arranged at equal intervals from top to bottom. Furthermore, a transmission plate is provided on the side of the mounting frame, and a through hole II is provided on the transmission plate. At the same time, each through hole II and the through hole I on the same horizontal plane are connected to a bolt. The transmission plate is fixedly connected to the mounting frame by bolts.

[0012] Preferably, each of the support rods is further fixedly connected to an auxiliary rod in the upper and lower axial directions at its lower end, and the auxiliary rod is slidably connected to the corresponding mounting frame.

[0013] Preferably, each of the limiting rods and each of the auxiliary rods is fitted with a compression spring on its outer side, and the two axial ends of the compression spring abut against the corresponding support rod and the mounting frame, respectively.

[0014] Preferably, each of the mounting frames is fixedly connected to a roller at its lower end, and the height of the lower end face of the roller is greater than the height of the lower end face of the mounting frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model relates to a sliding connection mechanism between a constrained installation frame and a limiting rod, wherein a limiting component is configured inside the channel body. This limiting component has a trapezoidal structure in its vertical projection and an arc-shaped structure in its horizontal projection, ensuring that the movement trajectory of the installation frame is not horizontal in height, resulting in dynamic changes in its vertical height during movement. As the installation frame rotates above the limiting component, impurities previously deposited at the bottom of the installation frame lose the support of the channel body and begin to shift. Simultaneously, due to the change in the height of the installation frame, the water depth where solid impurities are located decreases accordingly, allowing the impurities to smoothly enter the storage tank inside the limiting component for temporary storage. By implementing effective water pollution prevention measures, such as strictly controlling pollution source emissions and protecting water quality, this mechanism effectively prevents impurities from re-mixing into the water flow, thereby achieving effective separation of impurities from the water.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] See Figure 1 A building rainwater drainage and anti-clogging structure, whose structure is consistent with existing technology devices, includes a channel 1 for carrying and guiding water flow. The vertical cross-section of the channel 1 is U-shaped to effectively guide the water flow.

[0026] In existing technology devices, a longitudinal filter screen 9 is typically installed inside the channel body 1, i.e., within the U-shaped opening. The longitudinal filter screen 9 divides the water flow, ensuring smooth water flow through the pores while effectively intercepting impurities and preventing blockage of the channel body 1.

[0027] See Figure 1 and Figure 2 Unlike existing devices, this device has a vertically oriented positioning shaft 3 inside the channel body 1. Multiple horizontal support rods 7 are fixed to the side ends of the positioning shaft 3, evenly distributed around the central axis.

[0028] Meanwhile, each support rod 7 is fixedly connected to a limiting rod 5 in the upper and lower axial directions at its lower end.

[0029] See Figure 3 and Figure 5 Furthermore, this device also includes multiple mounting frames 11 inside the channel body 1, each corresponding to a specific limiting rod 5. Thus, each mounting frame 11 can be fitted onto the outside of its corresponding limiting rod 5, and the swing arm can be synchronously driven by a drive mechanism to achieve synchronized movement with the limiting rod 5. When the limiting rod 5 rotates with the positioning shaft 3, the mounting frame 11 can also rotate synchronously.

[0030] Therefore, the device also constrains the channel body 1 to have multiple longitudinal filters 9 installed inside, and these longitudinal filters 9 correspond one-to-one with multiple mounting frames 11. The longitudinal filters 9 are embedded in the mounting frames 11 and are fixedly connected by welding or bolts 16, etc.

[0031] It should be noted that in existing technology devices, since the position of the longitudinal filter 9 is fixed, impurities will inevitably accumulate near the longitudinal filter 9 during long-term use, causing the longitudinal filter 9 to become a new source of blockage.

[0032] This device allows for flexible adjustment of the position of the mounting frame 11 (i.e., the longitudinal filter screen 9) by continuously rotating the constraint mounting frame 11 with the positioning shaft 3, effectively preventing the accumulation of impurities in the water.

[0033] In particular, in order to ensure the effective interception of impurities and prevent the rotating mounting frame 11 from causing impurities to re-mix into the water, this device adopts a sliding connection between the mounting frame 11 and the limiting rod 5 to ensure that the mounting frame 11 can make stable up-and-down linear movements under the guidance of the limiting rod 5.

[0034] See Figure 2 and Figure 4 In addition, the device also has a limiting component 8 inside the channel body 1, which is located on one side of the positioning shaft 3. The limiting component 8 is ingeniously designed, presenting a trapezoidal projection in the vertical direction and an arc-shaped projection in the horizontal direction. This design causes the movement trajectory of each mounting frame 11 to fluctuate in height, that is, the mounting frame 11 will experience changes in height as it rotates with the positioning shaft 3.

[0035] Therefore, the device has a storage tank 14 inside the limiting member 8. When the mounting frame 11 rotates to the upper side of the limiting member 8, the impurities attached to the lower side of the mounting frame 11 will lose the support of the channel body 1 and can enter the storage tank 14 for temporary storage, thus preventing the impurities from being mixed into the water flow again during the rotation of the mounting frame 11.

[0036] It is worth noting that in practical applications, the buoyancy of solid materials in water is closely related to the depth of the water. When the mounting frame 11 is raised above the storage tank 14, the change in its height causes the depth of the accompanying solid impurities to decrease, making it easier for the impurities to enter the storage tank 14 (although some lightweight solid materials fail to sink due to insufficient buoyancy, this usually does not cause blockage of the channel 1).

[0037] In addition, such as Figure 4 As shown, to ensure that the width of the storage tank 14 is appropriate to facilitate the settling of solid impurities and to prevent the mounting frame 11 from sinking too much, this device adds a receiving groove 12 to the limiting member 8 and installs the transverse filter screen 13 therein. In practical applications, when the mounting frame 11 moves to the upper side of the limiting member 8, the transverse filter screen 13 can provide support for the mounting frame 11.

[0038] It is worth noting that the diameter of the filter holes in the transverse filter 13 is larger than that in the longitudinal filter 9, thereby ensuring that impurities can pass through the transverse filter 13 smoothly and settle into the storage tank 14.

[0039] In addition, the device has a roller 18 fixedly connected to the lower end of each mounting frame 11. The height of the lower end face of the roller 18 is greater than the height of the lower end face of the mounting frame 11 to prevent the mounting frame 11 from directly contacting the channel body 1, thereby reducing the frictional resistance when the mounting frame 11 rotates and ensuring that the mounting frame 11 moves more smoothly.

[0040] Further, see Figure 2 and Figure 3 In addition, each support rod 7 is fixedly connected to an auxiliary rod 6 in the upper and lower axial directions. These auxiliary rods 6 are movably connected to the corresponding mounting frame 11. At the same time, the auxiliary rods 6 and the limiting rods 5 are located at the two axial ends of the support rods 7, respectively. This design can avoid the mounting frame 11 being subjected to force on one side, thereby extending the service life of the device.

[0041] To prevent corrosion during long-term use from causing poor sliding between the mounting frame 11, auxiliary rod 6, and limit rod 5, a compression spring 10 is specially added to the outside of the limit rod 5 and auxiliary rod 6. The two ends of the spring are tightly fitted to the support rod 7 and the mounting frame 11, and the weight of the mounting frame 11 ensures smooth relative sliding between the components.

[0042] See Figure 1 Specifically, to achieve spontaneous rotation of the positioning shaft 3, a longitudinal baffle 4 is installed inside the channel body 1. One end of the baffle is fixedly connected to the channel body 1, and the other end forms an outlet 2 with the inner wall of the channel body 1, with the outlet 2 facing the limiting member 8. At this time, the eccentric impact of the water flow acts on the mounting frame 11, thereby realizing the spontaneous rotation process of the positioning shaft 3.

[0043] In addition, the position of the longitudinal baffle 4 is carefully designed, with one end away from the inner wall of the channel body 1 placed near the positioning shaft 3 and the limiting member 8, and the center line of the baffle is aligned with the tangent direction of the limiting member 8, so as to effectively guide the water flow to vertically impact the mounting frame 11 and ensure that the water can fully drive the positioning shaft 3 to rotate.

[0044] To adapt to the environment of the channel 1 at different depths and to ensure that the positioning shaft 3 can rotate smoothly when impacted by water, the device has a transmission plate 17 firmly installed on the mounting frame 11. With its wide contact surface with the water, the transmission plate 17 ensures that the water can effectively push the transmission plate 17, thereby driving the positioning shaft 3 to rotate.

[0045] Furthermore, the device has multiple equidistant through holes I 15 on the mounting frame 11, and through holes II on the transmission plate 17. After aligning the through holes II with the through holes I 15 on the same horizontal plane, bolts 16 are inserted together to tightly connect the transmission plate 17 to the mounting frame 11, ensuring functionality. By changing the number and fixing position of the transmission plates 17, this design can be adapted to water bodies of different depths.

[0046] In practical use, this utility model:

[0047] 1. Water flow diversion and preliminary filtration

[0048] This study employs a U-shaped channel structure 1 to support and guide water flow. A longitudinal filter screen 9 is installed within the channel 1 to initially divide the water body, ensuring smooth water flow through the filter screen's pores while effectively intercepting impurities and preventing clogging of the channel 1.

[0049] 2. The rotation of positioning shaft 3 drives the filter screen to move.

[0050] Rotating structure design: The channel body 1 is equipped with a positioning shaft 3 with vertical axial direction. Multiple equally spaced support rods 7 are fixed to the side ends of the shafts. A limiting rod 5 is fixed to the lower side of each support rod 7. Multiple mounting frames 11 correspond one-to-one with the limiting rods 5 and are sleeved on the outside of the limiting rods 5. The longitudinal filter screen 9 is embedded in the mounting frame 11 and fixed.

[0051] Rotational power mechanism: A longitudinal baffle 4 is installed inside the channel body 1, with one end fixed to the channel body 1 and the other end forming an outlet 2 facing the limiting component 8 with the inner wall of the channel body 1. The water flow eccentrically impacts the mounting frame 11, realizing the spontaneous rotation of the positioning shaft 3, which drives the mounting frame 11 and the longitudinal filter screen 9 to rotate continuously, changing the position of the longitudinal filter screen 9 and preventing the accumulation of impurities. The position and direction of the longitudinal baffle 4 guide the water flow to vertically impact the mounting frame 11, ensuring that the water can fully drive the positioning shaft 3 to rotate.

[0052] 3. Impurity separation and storage

[0053] Height adjustment mechanism: A limiting component 8 is installed inside the channel body 1. Its vertical projection is trapezoidal, and its horizontal projection is arc-shaped. As the positioning shaft 3 moves, the mounting frame 11 adjusts its height vertically under the constraint of the limiting component 8.

[0054] Impurity settling process: When the mounting frame 11 rotates to the upper side of the limiting member 8, the impurities accumulated on the lower side of the mounting frame 11 lose the support of the channel body 1. In addition, the change in height of the mounting frame 11 causes the water depth where the solid impurities are located to decrease, and the impurities then enter the storage tank 14 inside the limiting member 8 for temporary storage, thereby preventing them from mixing into the water again.

[0055] Filter support and filtration mechanism: A receiving groove 12 is provided on the limiting member 8, and a transverse filter 13 is installed. The transverse filter 13 supports the mounting frame 11 that moves to the upper side of the limiting member 8, and its filter hole diameter is larger than that of the longitudinal filter 9, ensuring that impurities can pass through the transverse filter 13 and settle into the storage tank 14.

[0056] 4. Adaptable to different water depths

[0057] Transmission plate 17 design: Transmission plate 17 is fixedly connected to the mounting frame 11. By utilizing its large contact area with the water, it is ensured that water at different depths can push transmission plate 17, thereby driving positioning shaft 3 to rotate.

[0058] Flexible installation method: Multiple through holes I15 are opened through the mounting frame 11 at equal intervals, and through holes II are opened through the transmission plate 17. The transmission plate 17 is fixed to the mounting frame 11 by bolts 16. The number and fixed position of the transmission plate 17 can be changed to adapt to different water depths.

[0059] 5. Reduce friction and ensure smooth sliding

[0060] Roller 18 design: Rollers 18 are fixedly connected to the lower end of each mounting frame 11. The lower end face of the roller 18 is higher than the lower end face of the mounting frame 11 to avoid direct contact between the mounting frame 11 and the channel body 1, thereby reducing rotational friction resistance.

[0061] The spring-assisted mechanism is ingeniously designed. Compression springs 10 are fitted on the outer sides of both the limiting rod 5 and the auxiliary rod 6. The two ends of the springs are tightly connected to the support rod 7 and the mounting frame 11. With the help of the self-weight of the mounting frame 11, it is ensured that the mounting frame 11 can slide smoothly relative to the limiting rod 5 and the auxiliary rod 6, effectively avoiding the interference of corrosion on the sliding performance.

[0062] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
