Description

Technical Field

[0001] This utility model relates to the field of drainage equipment technology, and in particular to a filter basket for rainwater grates to prevent leaf clogging. Background Technology

[0002] A storm drain grate is a device used to block debris from a sewer opening. Its main function is to allow rainwater to flow smoothly into the underground drainage network while intercepting leaves and garbage to prevent these debris from entering the drainage pipes and causing blockages. The anti-leaf clogging filter basket serves as an auxiliary component, improving the storm drain grate's anti-clogging performance.

[0003] The rain grate's anti-leaf clogging filter basket, without affecting the normal flow of rainwater into the drainage pipe, provides secondary filtration and interception of debris such as fallen leaves that easily cause blockages. The filter basket's structural design concentrates fallen leaves and other debris inside, facilitating later cleaning. If the filter basket is not cleaned in time, debris will accumulate inside, gradually clogging the filter basket's mesh and affecting the rainwater infiltration rate. Later, a tilted mesh and flow guide channel structure was used, causing fallen leaves to automatically gather to one side of the basket under the impact of water flow, reducing clogging of the overall mesh and extending the cleaning cycle. However, when cleaning the filter basket, workers need to remove it to remove fallen leaves, which is cumbersome and reduces work efficiency. Utility Model Content

Detailed Implementation

[0017] 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.

[0018] Reference Figure 3 and Figure 6This utility model provides an embodiment of a rain grate filter basket to prevent leaf blockage, comprising a drainage basket 1 and a rain cover plate 4. A lifting and tipping mechanism 2 is provided on the rear side of the inner bottom wall of the drainage basket 1, used to tip off leaves from the drainage basket 1. A locking and fixing mechanism 3 is provided on both the left and right sides of the lower part of the rain cover plate 4, used to fix and disassemble the drainage basket 1. The lifting and tipping mechanism 2 includes an electric push rod 201, which is fixedly connected to the rear side of the inner bottom wall of the drainage basket 1. A support plate 202 is fixedly connected to the output end of the electric push rod 201. Guide rods 203 are slidably connected to the left and right sides of the rear end of the support plate 202, restricting the movement direction of the support plate 202. The guide rods 203 are fixedly connected to the drainage basket 1. A motor 204 is fixedly connected to the top right side of the support plate 202, and a first gear 205 is fixedly connected to the output end of the motor 204. The top left and right ends of the support plate 202 are fixedly connected to the first fixing plate 206. The middle right side of the first fixing plate 206 is fixedly connected to the support rod 207 and the support rack 208. The outer wall of the support rod 207 is slidably connected to the rack 208. The first gear 205 is meshed with the rack 208. The upper right side of the first fixing plate 206 is rotatably connected to the first rotating shaft 209. The outer wall of the first rotating shaft 209 is fixedly connected to the sieve plate 210 to block debris and allow rainwater to flow down. The right end of the first rotating shaft 209 is fixedly connected to the second gear 211, which meshes with the rack 208. The outer side of the electric push rod 201 is provided with a telescopic sleeve 5, which extends and retracts with the electric push rod 201. The telescopic sleeve 5 is fixedly connected to the support plate 202. The outer side of the motor 204 is provided with a protective shell 6 to prevent water from entering the motor 204. The protective shell 6 is fixedly connected to the support plate 202. Specifically, when cleaning personnel need to clear fallen leaves from the drainage basket 1, they first flip up the rainwater cover 4 to open it, then activate the electric push rod 201. The electric push rod 201 is a DC electric push rod. Through a reduction gearbox, the speed is reduced and the torque increased, driving the lead screw to rotate, converting the rotational motion into the linear motion of the nut, which in turn pushes the push rod to extend or retract. The extension of the electric push rod 201 drives the connected support plate 202 to move upwards along the guide rod 203. When the support plate 202 rises to contact the limit plate 7, the electric push rod 201 stops working, keeping the support plate 202 at its current height. Then, the motor 204 is activated. The motor 204 is a permanent magnet DC motor. It utilizes the electromagnetic force generated by the stator magnetic field and the current in the rotor winding to form torque, causing the rotor to rotate. The commutator automatically changes the direction of the current in the armature winding to ensure the torque direction remains constant, achieving continuous rotation. The operation of the motor 204 drives the first gear 205 to rotate. With the first gear 205 and rack 208 in mesh, rack 208 moves forward as the first gear 205 rotates. Since rack 208 is also meshed with the second gear 211, the movement of rack 208 drives the second gear 211 to rotate, which in turn drives the first rotating shaft 209 connected to it to rotate. This causes the screen plate 210 connected to it to flip upwards, dumping fallen leaves and debris accumulated on top of the screen plate 210 to the outside, preventing fallen leaves from clogging the rain cover 4 and reducing its drainage function. It also facilitates the centralized disposal of these debris by cleaning personnel. When the electric push rod 201 is working, the telescopic sleeve 5 extends synchronously with the extension of the push rod 201, isolating the main body of the electric push rod 201 from the external environment, preventing rainwater, dust, etc., from entering the electric push rod 201 and causing damage. The protective shell 6 installed on the outside of the motor 204 prevents rainwater from entering the motor 204, ensuring that the motor 204 can work normally even in rainy weather.

[0019] Reference Figure 1 , Figure 4 and Figure 5 The locking and fixing mechanism 3 includes a fixing sleeve 301, which is rotatably connected to the rainwater cover plate 4. A second fixing plate 302 is fixedly connected to the bottom left and right sides of the fixing sleeve 301. A third fixing plate 303 is fixedly connected to the upper middle left and right sides of the second fixing plate 302. A second rotating shaft 304 is rotatably connected to the upper part of the third fixing plate 303. A pressure plate 305 is fixedly connected to the outer wall of the second rotating shaft 304 for fixing the water distribution basket 1. A T-shaped plate 306 is slidably connected to the middle of the pressure plate 305 for locking the pressure plate 305. The T-shaped plate 306 is rotatably connected to the second fixing plate 302. A rain shield 8 is fixedly connected to the top of the rainwater cover plate 4 to reduce debris entering the water distribution basket 1. Specifically, when the drainage basket 1 needs to be replaced due to rust or damage, first flip the rainwater cover plate 4 upwards, then rotate the T-shaped plate 306 so that the direction of the T-shaped plate 306 is the same as the direction of the hole on the pressure plate 305. Next, flip the pressure plate 305 upwards so that it passes through the T-shaped plate 306. When the pressure plate 305 is flipped to the top, avoiding the drainage basket 1, grasp the handle 9 on the drainage basket 1 and remove the damaged drainage basket 1 from the fixing sleeve 301. Then, put the new drainage basket 1 into the fixing sleeve 301, so that the left and right sides of the drainage basket 1 are aligned. The edge rests on the second fixed plate 302, and then the pressure plate 305 is flipped downwards so that it passes through the T-shaped plate 306. When the pressure plate 305 contacts the edge of the water distribution basket 1 and applies a certain pressure to it, the T-shaped plate 306 is rotated so that the direction of the T-shaped plate 306 is perpendicular to the direction of the hole on the pressure plate 305, thus fixing the pressure plate 305 and fixing the water distribution basket 1. The rain shield 8 on the top of the rain cover 4 can make the fallen leaves fall to the front and rear sides of the rain cover 4, reducing the number of fallen leaves entering the interior of the rain cover 4 and preventing the rain cover 4 and the water distribution basket 1 from being blocked.

[0020] Reference Figure 2 and Figure 7 A handle 9 is fixedly connected to the upper front side of the water distribution basket 1 for easy gripping; multiple drainage holes 10 are provided on the bottom wall of the water distribution basket 1 to facilitate rainwater to flow into the underground drainage network. Specifically, the handle 9 is easy for staff to grip, saving them effort, and the drainage holes 10 at the bottom of the water distribution basket 1 allow rainwater entering the interior to flow into the underground drainage network, ensuring smooth rainwater discharge.

[0021] Working principle: When cleaning personnel need to clean the fallen leaves in the drainage basket 1, the rainwater cover 4 is flipped upwards, the electric push rod 201 is activated, the push rod extends and the support plate 202 rises along the guide rod 203. When the support plate 202 rises to contact the limit plate 7, it stops. Then the motor 204 is activated and the first gear 205 rotates. Since the first gear 205 and the rack 208 are in a meshing state, the rack 208 will move forward. Since the rack 208 is in a meshing state with the second gear 211, the rack 208 will drive the second gear 211 to rotate. The second gear 211 drives the first rotating shaft 209 connected to it to rotate, causing the screen plate 210 to flip upwards, dumping the debris accumulated on top to the outside of the rainwater cover 4, preventing the fallen leaves from clogging the rainwater cover 4 and reducing its drainage function, while also facilitating cleaning. When the drainage basket 1 needs to be replaced due to rust or other reasons, flip the rainwater cover plate 4 upwards, rotate the T-shaped plate 306 so that the direction of the T-shaped plate 306 is the same as the direction of the hole in the pressure plate 305, flip the pressure plate 305 upwards so that it passes through the T-shaped plate 306, and when the pressure plate 305 is completely away from the top of the drainage basket 1, hold the handle 9 to take out the drainage basket 1, and then place the replacement drainage basket 1 inside the fixing sleeve 301 so that the left and right edges of the drainage basket 1 rest on the second fixing plate 302, and then flip the pressure plate 305 downwards so that it passes through the T-shaped plate 306. When the pressure plate 305 contacts the edge of the drainage basket 1 and applies a certain pressure to it, rotate the T-shaped plate 306 to fix the pressure plate 305, and the drainage basket 1 will be fixed accordingly.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
