Description
Technical Field
[0001] This invention belongs to the field of road water supply and drainage technology, specifically relating to a drain outlet garbage cleaning device based on a simple pole structure. Background Technology
[0002] As a core node of the urban drainage system, the unobstructed flow of municipal sewer inlets directly affects the city's flood control capabilities and the safety of residents during the rainy season. However, traditional sewer inlets face serious clogging problems during operation—large-diameter debris such as leaves, plastic bottles, and textiles flow in with rainwater and easily accumulate at the inlets, causing a 60%-80% reduction in drainage efficiency. In extreme cases, this can even lead to road flooding, traffic disruptions, and backflow into residential areas, posing a significant threat to urban operations.
[0003] To address this issue, municipal departments have long relied on manual cleaning. However, manual cleaning not only requires traffic disruption for 2-3 hours per instance, but labor costs also account for over 70% of the total cost of drain maintenance. More importantly, the presence of toxic gases such as hydrogen sulfide and sharp debris like broken glass in the sewers poses extremely high safety risks to workers. Therefore, developing an automated, low-cost, and highly adaptable drain cleaning system has become a crucial technological bottleneck that urgently needs to be overcome in the field of municipal engineering machinery.
[0004] Existing technical solutions for cleaning sewer outlets can be mainly divided into three categories: 1. Fixed filter screen: This type of filter screen intercepts debris by setting different pore sizes. However, the core drawback of this type of filter screen is that it is "passive interception" - debris cannot be automatically discharged after it accumulates on the surface of the filter screen. It needs to be manually disassembled and cleaned 1-2 times a week, which not only increases the workload of maintenance, but also causes drainage interruption during the cleaning period.
[0005] 2. Mechanically driven cleaning equipment: This method uses high-pressure water guns to flush loose debris from pipes. However, this method relies on electricity and is ineffective against tangled garbage (such as branches and plastic bags). In addition, the narrow and humid environment of municipal sewers can easily cause short circuits in electrical equipment, with a failure rate of over 30%, making it impossible to operate stably.
[0006] 3. Intelligent robot system: Although it can achieve automated dredging, the equipment cost is as high as 500,000 yuan per set, and it requires a complex sensing and control system, making it difficult to promote on a large scale in municipal engineering.
[0007] None of the aforementioned existing technologies have effectively resolved the "efficiency-cost-safety" dilemma in sewer cleaning: fixed filters suffer from secondary clogging due to "passive interception"; mechanical cleaning equipment has poor adaptability due to "electricity dependence"; and intelligent robots cannot be widely adopted due to "high cost." These problems mean that traditional sewer cleaning methods can never meet the municipal engineering requirements for "low maintenance and high unobstructed flow."
[0008] Therefore, there is an urgent need for a sewer cleaning system based on a simple rod structure, which does not require electricity and can dynamically intercept and clean up debris, in order to overcome the shortcomings of existing technologies and achieve full-process automation of "automatic interception-active cleaning-cyclical circulation", thereby reducing labor costs, improving drainage efficiency, and ensuring the stable operation of urban drainage systems. Summary of the Invention
[0009] To address the aforementioned shortcomings of existing technologies, this invention provides a drain cleaning device based on a simple rod structure, which solves the problems of low efficiency and high cost of existing cleaning methods after drain blockage.
[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A drain cleaning device based on a simple rod structure is provided, including a rainwater deceleration component, a garbage removal component, and a garbage collection component; The rainwater deceleration component includes a buffer tilting platform, the high side of which is in contact with the ground, deceleration grooves are provided on the buffer slope of the buffer tilting platform, and the garbage removal component is provided on the low side of the buffer tilting platform. The waste removal component includes a mesh baffle, fixed rods, and a fixed truss. The mesh baffle is located on the lower side of the buffer tilting platform, and a preset distance is provided between the mesh baffle and the lower side of the buffer tilting platform, which is the waste pre-storage area. The fixed rods and the fixed truss are located on both sides of the mesh baffle. The fixed rods are located within the waste pre-storage area and are vertically arranged. A drive rod is hinged to the top of the fixed rod via a hinge with a torsion spring. A mesh brush is hinged to the other end of the drive rod, and the mesh brush is located within the waste pre-storage area. A water storage tank is hinged to the bottom of the fixed truss, and the top inlet of the water storage tank is located below the outlet of the mesh baffle. A fixed pulley is provided on the bottom side wall of the fixed rod, and a rope is provided on the fixed pulley. The two ends of the rope are fixed to the lower end of the water storage tank and the other end of the drive rod, respectively. The waste collection component includes a waste trough located at one end of the waste pre-storage area, and a waste inlet communicating with the interior of the waste trough is provided on one side of the waste trough. The waste inlet is connected to the end of the waste pre-storage area. After rainwater is slowed down by the deceleration ripples, large-diameter garbage is intercepted by the mesh baffle, and the water flows into the water storage tank through the mesh baffle. As the water volume increases, the water storage tank tilts and pours out the water. The rope changes from taut to slack, the hinge opens and drives the drive rod to rotate around its hinge point, which drives the mesh brush to push the garbage in the garbage pre-storage area to the garbage inlet and into the garbage bin. After the water in the water storage tank is drained, the water storage tank returns to its original position, the rope tightens, the hinge is pulled to close, and the drive rod and mesh brush return to their original positions.
[0011] The present invention discloses a drain cleaning device based on a simple rod structure. The entire cleaning process requires no external electricity or manual intervention, and is driven solely by the gravity of rainwater and the mechanical structure. This solves the problems of low efficiency and high cost of existing cleaning methods after sewer blockage.
[0012] Furthermore, the tilt angle of the buffer tilting platform is 10°~15°, which can be adjusted according to the actual garbage situation in the area. The deceleration grooves allow rainwater to flow smoothly down the rain grate and slow down, reducing the impact on the mesh baffle and making it easier for garbage carried in the rainwater to remain on the plane in front of the mesh baffle.
[0013] Furthermore, the mesh baffle has an aperture of 10mm to 15mm. This aperture range can effectively intercept the main culprits causing sewer blockages, such as leaves, plastic pieces, and packaging bags, while allowing water flow and small particles of silt to pass through smoothly, avoiding blockage of the mesh baffle itself and ensuring the basic unobstructed drainage channel.
[0014] Furthermore, the lower end of the water storage tank is equipped with an adjustable counterweight, which can adjust the trigger threshold according to the local rainfall intensity and garbage volume, avoiding the problem of easy clogging of the fixed filter or mismatch of the frequency of the mechanical cleaning device, and significantly improving the applicability of the device in different regions.
[0015] Furthermore, the water storage tank is provided with a groove, and the rope segment is located in the groove to limit rope displacement and prevent slippage, thereby effectively fixing the rope.
[0016] Furthermore, the mesh brush is hinged to the other end of the drive rod via a hinge point; the width of the mesh brush is the same as the width of the waste pre-storage area. The "hinge" allows the mesh brush to better conform to the ground, improving cleaning efficiency. The "same width" ensures thorough cleaning without blind spots.
[0017] Furthermore, a baffle is provided at the waste inlet. The baffle is a one-way baffle. When the baffle is pushed open by the mesh brush, it opens to the inside of the waste trough, and the waste enters the waste trough. When the mesh brush leaves the baffle, the baffle closes and prevents the waste from returning from the waste trough to the waste pre-storage area.
[0018] Furthermore, the garbage chute is equipped with elastic carrying straps and a transparent observation window. The elastic carrying straps greatly facilitate the garbage collection work of sanitation workers and reduce their labor intensity. The transparent observation window allows for a direct assessment of the garbage load level, enabling on-demand cleaning and avoiding unnecessary labor.
[0019] This invention provides a drain cleaning device based on a simple rod structure. Its advantages include: Utilizing the gravity of rainwater, the cleaning mechanism is triggered by the tilting of a water storage tank, eliminating the need for electricity or manual intervention, thus saving energy and reducing operating costs. It solves the problems of low efficiency and high cost associated with existing drain cleaning methods after sewer blockage. The entire device consists only of simple mechanical components such as rods, pulleys, ropes, and a water storage tank, without complex electronic components, making it less prone to damage over long-term use and reducing maintenance costs. The device is adaptable to existing drain structures and suitable for various scenarios such as urban roads, parks, and residential areas, especially suitable for areas with heavy rainfall or dense leaf litter. Its low-cost materials and zero-energy operation make large-scale deployment economically advantageous. Attached Figure Description

[0024] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.
[0025] like Figures 1-2 As shown, the present invention provides a drain garbage cleaning device based on a simple rod structure, the core of which consists of three main modules: a rainwater deceleration component, a garbage removal component, and a garbage collection component.
[0026] The rainwater deceleration component includes a buffer tilting platform 1, the higher side of which is in contact with the ground. The buffer tilting platform 1 has deceleration grooves on its buffer slope, and the garbage removal component is located on its lower side. Specifically, the deceleration grooves are made of stainless steel. The tilt angle of the buffer tilting platform 1 is 10°~15°, which can be adjusted according to the actual garbage situation in the area. The deceleration grooves allow rainwater to flow smoothly down the rainwater grate and decelerate, reducing the impact on the mesh baffle 2 and making it easier for garbage carried in the rainwater to remain on the plane in front of the mesh baffle 2.
[0027] The waste removal component includes a mesh baffle 2, a fixing rod 3, and a fixing truss 4. The mesh baffle 2 is located on the lower side of the buffer tilting platform 1, and a preset distance is provided between the mesh baffle 2 and the lower side of the buffer tilting platform 1. The preset distance is the waste pre-storage area. The fixing rod 3 and the fixing truss 4 are located on both sides of the mesh baffle 2. The fixing rod 3 is located in the waste pre-storage area and is vertically arranged. A drive rod 6 is hinged to the top of the fixing rod 3 through a hinge 5. The hinge 5 is a hinge with a torsion spring. A mesh brush 7 is hinged to the other end of the drive rod 6. The mesh brush 7 is located in the waste pre-storage area. A water storage tank 8 is hinged to the bottom of the fixing truss 4. The top inlet of the water storage tank 8 is located below the outlet of the mesh baffle 2. The water storage tank 8 is made of lightweight stainless steel or engineering plastic. A fixed pulley 9 is provided on the bottom side wall of the fixed rod 3, and a rope 10 is provided on the fixed pulley 9. The two ends of the rope 10 are respectively fixed to the lower end of the water storage tank 8 and the other end of the drive rod 6.
[0028] Specifically, such as Figure 3 As shown, the mesh baffle 2 has a hole diameter of 10mm to 15mm. This hole diameter range can effectively intercept the main culprits causing sewer blockage, such as leaves, plastic pieces, and packaging bags, while allowing water flow and small particles of mud and sand to pass through smoothly, avoiding blockage of the mesh baffle 2 itself and ensuring the basic unobstructed drainage channel.
[0029] The lower end of the water storage tank 8 is equipped with an adjustable counterweight 12. The material of the adjustable counterweight 12 can be cast iron. The trigger threshold can be adjusted according to the local rainfall intensity and garbage volume to avoid the problem of easy clogging of the fixed filter or mismatch of the frequency of the mechanical cleaning device, and significantly improve the applicability of the device in different regions.
[0030] The water storage tank 8 is provided with a groove 13, and the rope segment of the rope 10 is located in the groove 13 to limit the displacement of the rope 10 and prevent slippage, which can effectively fix the rope 10.
[0031] like Figure 4As shown, the mesh brush 7 is hinged to the other end of the drive rod 6 via hinge point 14; the width of the mesh brush 7 is the same as the width of the waste pre-storage area, and the "hinge" allows the mesh brush 7 to better conform to the ground, improving cleaning efficiency. The "same width" ensures that there are no blind spots in the cleaning.
[0032] The waste collection component includes a waste trough 11 located at one end of the waste pre-storage area. A waste inlet communicating with the interior of the waste trough 11 is provided on one side, and the waste inlet connects to the end of the waste pre-storage area. A waste inlet baffle 15 is provided at the waste inlet. The waste inlet baffle 15 is a one-way baffle, made of 1.5mm to 2mm thick stainless steel sheet, and uses a hinge structure. It is in a closed state by default and can be equipped with a lightweight spring for assisted reset. When the waste inlet baffle 15 is pushed open by the mesh brush 7, it opens inwards towards the waste trough 11, allowing waste to enter. When the mesh brush 7 leaves the waste inlet baffle 15, the waste inlet baffle 15 closes, preventing waste from returning from the waste trough 11 to the waste pre-storage area.
[0033] Preferably, but not limited to, the garbage chute 11 is equipped with an elastic carrying strap 16 and a transparent observation window. The elastic carrying strap 16 is made of sun-resistant rubber, which greatly facilitates the garbage collection work of sanitation workers and reduces their labor intensity. The transparent observation window allows for a direct visual assessment of the garbage load level, enabling on-demand cleaning and avoiding unnecessary labor.
[0034] The working process of the drain garbage cleaning device based on a simple rod structure is as follows: Rainwater flows in from the rain grate, and after being slowed down by the deceleration groove, large-diameter garbage is intercepted by the mesh baffle 2 and temporarily retained in the garbage pre-storage area in front of the mesh baffle 2. The water flows into the water storage tank 8 through the mesh baffle 2. As the water volume in the water storage tank 8 increases, the center of gravity shifts. When the water volume reaches a threshold, the water storage tank 8 tilts and pours out the water. At this time, the rope 10 changes from taut to slack, the alloy hinge opens, and the fixation on the drive rod 6 is released. Under the thrust and gravity of the hinge 5, the drive rod 6 rotates around its hinge point 14, driving the mesh brush 7 to push open the discharge port baffle 15 and sweep the garbage into the garbage trough 11. The hinge point 14 helps to reduce the impact and push open the discharge port baffle 15 in advance. After the water in the water storage tank 8 is drained, the adjustable counterweight 12 can be used to reset the water storage tank 8, the rope 10 is tightened, the alloy leaf is pulled to close, the drive rod 6 and the mesh brush 7 are reset, and the discharge port baffle 15 is closed to prevent garbage from returning to the garbage pre-storage area.
[0035] Finally, sanitation workers periodically open the garbage bin 11 using the elastic handle 16 to clean out the garbage inside.
[0036] In summary, the sewer cleaning device of the present invention utilizes the gravity of rainwater and triggers the cleaning mechanism by tilting the water storage tank 8. It requires no electricity or manual intervention, saving energy and reducing operating costs. This solves the problems of low efficiency and high cost associated with existing sewer cleaning methods after blockage. The entire device consists only of simple mechanical components such as rods, pulleys, ropes 10, and the water storage tank 8, without complex electronic components. It is not easily damaged during long-term use and has low maintenance costs. The entire device is adaptable to existing sewer structures and suitable for various scenarios such as urban roads, parks, and residential areas, especially suitable for areas with heavy rainfall or dense leaf litter. Its low-cost materials and zero-energy operation characteristics make large-scale promotion a significant economic advantage.
