Description

Technical Field

[0001] The utility model relates to the technical field of rainwater collection, in particular to a sludge scraping device for a PP module reservoir with a backwashing function. Background Art

[0002] With the acceleration of the urbanization process and the improvement of the demand for rainwater resource management, the design and application of rainwater collection and utilization systems have become increasingly important. As an efficient rainwater collection and storage solution, PP module reservoirs have been widely used in urban infrastructure and ecological construction. Due to their advantages such as light weight, high strength, flexible modular assembly, and short construction period, PP module reservoirs have gradually replaced traditional reinforced concrete reservoirs and become an important part of the rainwater resource management system.

[0003] During the operation of traditional reinforced concrete reservoirs, a large amount of sludge and impurities are likely to accumulate at the bottom of the pool, affecting the water storage capacity and water quality of the reservoir. Such reservoirs can be emptied to allow personnel to enter the reservoir for manual silt removal to restore their functions. However, with the widespread application of PP module reservoirs, new technical problems have emerged. Since PP module reservoirs adopt a closed structure and their internal space is complex, it is impossible to empty them and allow personnel to enter for manual silt removal like traditional reinforced concrete reservoirs. This makes it very difficult to clean the sludge in PP module reservoirs during long-term use, affecting the normal operation of the system.

[0004] Existing PP module reservoirs usually rely on backwashing technology to remove sludge and impurities at the bottom of the pool. However, these devices still have deficiencies in terms of cleaning efficiency, cleaning coverage, and anti-blocking ability. Especially when faced with a large area of sludge accumulation, existing equipment often cannot completely clean the bottom of the pool, resulting in long-term sludge accumulation, further affecting the effective volume and water quality safety of the reservoir.

DETAILED DESCRIPTION

[0040] See also Figures 1 to 8As shown in the figure, a silt scraping device for a pp module reservoir with a backwashing function includes a reservoir 1, in which a silt scraping mechanism 2 cooperating with the reservoir 1 is provided, and a backwashing mechanism 3 cooperating with the silt scraping mechanism 2 is provided on the reservoir 1; the silt scraping mechanism 2 includes a scraping plate assembly 21 cooperating with the bottom of the reservoir 1, a limiting guide rod assembly 22 cooperating with the scraping plate assembly 21 is provided in the reservoir 1, and a bidirectional driving assembly 23 for driving the scraping plate assembly 21 to move along the limiting guide rod assembly 22 is provided on the reservoir 1;

[0041] The backwashing mechanism 3 includes a backwashing bracket 31 provided at one end of the reservoir 1, a backwashing pump 32 is provided on the backwashing bracket 31, a sewage well 33 cooperating with the backwashing pump 32 and used for collecting silt and impurities at the bottom of the reservoir 1 is provided at one end of the reservoir 1, and a backwashing unit cooperating with the backwashing pump is provided in the reservoir.

[0042] Specifically, the reservoir 1 serves as the main structure for collecting and storing rainwater, and at the same time provides a space for silt scraping and backwashing operations. The silt scraping mechanism 2 directly contacts the bottom of the reservoir 1 to scrape the silt and impurities deposited at the bottom of the pool. The backwashing mechanism 3 provides high-pressure water flow to wash the bottom of the reservoir 1 to assist the scraping plate assembly 21 in removing silt. In this silt scraping mechanism 2, the scraping plate assembly 21 contacts the bottom of the reservoir 1, and through the guiding action of the limiting guide rod assembly 22, it ensures that the scraping plate 211 moves smoothly and scrapes the silt from the bottom of the pool. The limiting guide rod assembly 22 provides guidance and limitation for the scraping plate assembly 21 to ensure that the scraping plate assembly 21 moves in a straight line during the movement and prevents it from deviating from the track. The bidirectional driving assembly 23 drives the scraping plate assembly 21 to move back and forth along the limiting guide rod assembly 22 to achieve a comprehensive cleaning of the silt, realizes the automatic back-and-forth movement of the scraping plate assembly 21, and ensures that the entire bottom surface of the reservoir 1 can be cleaned.

[0043] In this backwashing mechanism 3, the backwashing bracket 31 is used to fix the backwashing pump 32 and its related components, avoid its shaking during operation, and ensure its stable operation. The backwashing pump 32 provides high-pressure water flow to drive the backwashing process.

[0044] Further, the scraping plate assembly 21 includes a scraping plate 211 located in the reservoir 1 and contacting the bottom of the reservoir 1, and limiting guide rod assemblies 22 cooperating with the scraping plate 211 are provided at both ends of the scraping plate 211;

[0045] The limiting guide rod assembly 22 includes a limiting frame 221, a limiting groove 222 is formed in the limiting frame 221, a limiting rod 223 is arranged in the limiting groove 222, a limiting slider 224 which is slidably matched with the limiting rod 223 and connected to the scraping plate 211 is arranged on the limiting rod 223, a sliding groove which is slidably matched with the limiting rod 223 is formed in the limiting slider 224, and buffer springs 225 which are matched with the limiting rod 223 are arranged on both sides of the limiting slider 224.

[0046] Specifically, the scraping plate assembly 21 is the part directly in contact with the bottom of the reservoir 1. Its main function is to move smoothly along the bottom of the reservoir 1 under the guiding action of the limiting guide rod assembly 22, scrape up the silt and impurities deposited on the bottom of the pool and push them towards the sewage well 33, so as to achieve the purpose of cleaning the bottom of the reservoir 1. The scraping plate assembly 21 solves the problem that the scraping plate 211 may deviate or be damaged due to the possible unevenness of the bottom of the pool during the cleaning process. By designing a reasonable shape and material of the scraping plate 211, it is ensured that it can work reliably under different conditions and avoid damaging the bottom of the pool. However, the main function of the limiting guide rod assembly 22 is to provide guiding and limiting functions for the scraping plate assembly 21 to ensure that the scraping plate 211 can move smoothly along a predetermined track during the movement. The limiting guide rod assembly 22 generally includes components such as a limiting frame 221, a limiting groove 222, a limiting rod 223, a limiting slider 224 and buffer springs 225. These components work together to ensure that the scraping plate assembly 21 moves in a straight line during the movement. The limiting guide rod assembly 22 solves the problem that the scraping plate 211 may deviate from the track or the scraping plate 211 may deviate due to the unevenness of the bottom of the pool during the movement. Through the cooperation between the limiting slider 224 and the limiting rod 223, and the action of the buffer spring 225, the scraping plate 211 can maintain the correct traveling direction even when encountering small protrusions or depressions on the bottom of the pool, thus avoiding damage or failure of the scraping plate assembly 21.

[0047] Further, the backwashing unit includes a backwashing main pipe 34 connected to the output end of the backwashing pump 32, a plurality of backwashing hoses 35 are arranged on the backwashing main pipe 34, and a plurality of backwashing pipe assemblies 36 which are matched with the backwashing hoses 35 are arranged on the scraping plate assembly 21;

[0048] A plurality of mounting holes for mounting the backwashing pipe assembly 36 are uniformly formed in the scraping plate 211 along the length direction thereof. The backwashing pipe assembly 36 includes a threaded fastening cylinder 361 adapted to the mounting holes. Two nuts 362 adapted to the scraping plate 211 are provided on the threaded fastening cylinder 361. Spray pipes 363 are provided at both ends of the threaded fastening cylinder 361. A plurality of spray openings 364 are formed in the spray pipes 363. One of the spray pipes 363 is connected to the backwashing hose 35. In use, the threaded fastening cylinder 361 passes through the mounting holes, and the two nuts 362 are respectively located on both sides of the scraping plate 211 and in contact with the scraping plate 211.

[0049] Specifically, the backwashing main pipe 34 and the backwashing hose 35 convey high-pressure water flow to the backwashing pipe assembly 36 on the scraping plate assembly 21. The backwashing pipe assembly 36 is mounted on the scraping plate assembly 21 and connected to the backwashing hose 35 to ensure uniform distribution of water flow during the backwashing process, effectively scour the bottom of the pool, and assist the scraping plate 211 in cleaning. The sewage well 33 is used to collect the sludge and impurities after being cleaned by the scraping plate 211 and the backwashing pipe, and effectively discharge them through the sewage well 33. It provides an effective sewage discharge channel for the whole system, ensures that the sludge and impurities can be quickly discharged, does not accumulate at the bottom of the reservoir 1, and avoids secondary pollution.

[0050] Meanwhile, the mounting holes are mainly used for mounting the backwashing pipe assembly 36. The backwashing pipe assembly 36 is quickly installed and disassembled by means of fixing with the threaded fastening cylinder 361 and the nuts 362. In the backwashing pipe assembly 36, the threaded fastening cylinder 361 passes through the mounting holes and is connected to the scraping plate assembly 21, and is fixed by the nuts 362 on both sides to ensure the stability of the backwashing pipe assembly 36. The nuts 362 are used to fasten the threaded fastening cylinder 361 to ensure that the backwashing pipe assembly 36 does not loosen during operation. The spray pipes 363 are key components of the backwashing pipe assembly 36. A plurality of spray openings 364 are uniformly distributed thereon. These spray openings 364 can disperse the high-pressure water flow into fine jet streams and evenly spray them on the moving path of the scraping plate assembly 21. The design of the spray openings 364 ensures that the high-pressure water flow can be ejected at an appropriate angle and speed, which helps to loosen and remove the sludge and impurities deposited at the bottom of the pool.

[0051] Generally speaking, the design of the mounting holes solves the problem of how to conveniently and quickly install and disassemble the backwashing pipe assembly 36, facilitating maintenance. Through the combination of the threaded fastening cylinder 361 and the nut 362, not only are the installation steps simplified, but also the later maintenance and replacement are facilitated, the maintenance difficulty is reduced, and the usability and flexibility of the equipment are improved. This design enables users to easily disassemble the backwashing pipe assembly 36 for cleaning or replacement when needed, ensuring the long-term stable operation of the system. The backwashing pipe assembly 36 solves the problem of how to ensure that the backwashing water can be evenly distributed along the movement path of the scraper 211, thereby improving the cleaning effect. Through the carefully designed spray pipe 363 and spray ports 364, the high-pressure water can cover the entire working area of the scraper assembly 21, helping the scraper 211 to more effectively remove silt and improving the cleaning efficiency and quality.

[0052] Further, the bidirectional driving assembly 23 includes two winding brackets 231 horizontally arranged on both sides of the reservoir 1 respectively, and the two winding brackets 231 are symmetrically arranged. The driving frame is horizontally provided with a rotating shaft 232 that is rotationally matched with the driving frame and is arranged parallel to the scraper 211. A plurality of driving rollers 233 are arranged on the rotating shaft 232, and a traction rope 234 for driving the scraper 211 to move along the limiting guide rod assembly 22 is arranged on the driving roller 233;

[0053] A steering unit 235 matched with the traction rope 234 is arranged on the reservoir 1. A first bevel gear 2364 is arranged at one end of the rotating shaft 232, and a driving unit 236 that is matched with the first bevel gear 2364 and is used to drive the rotating shaft 232 to rotate is arranged at one end of the reservoir 1.

[0054] Further, the driving unit 236 includes a driving bracket 2361 horizontally arranged at one end of the reservoir 1. A plurality of sliding sleeves 2362 are arranged on the driving bracket 2361. A driving shaft 2363 that is slidably matched with the sliding sleeve 2362 is arranged in the sliding sleeve 2362. Second bevel gears 2365 are arranged at both ends of the driving shaft 2363;

[0055] An electric push rod 2366 for driving the driving shaft 2363 to slide along the axial direction of the driving shaft 2363 is arranged in the reservoir 1. The telescopic direction of the electric push rod 2366 is consistent with the axial direction of the driving shaft 2363. The telescopic end of the electric push rod 2366 is fixedly connected to the driving shaft 2363. A square driving groove is formed at one end of the driving shaft 2363. A driving motor 2367 is arranged on the outer wall of the reservoir 1. A driving rod 2368 that is square and is matched with the driving groove is arranged at the output end of the driving motor 2367;

[0056] During use, the electric push rod 2366 will drive the second bevel gear 2365 on the drive shaft 2363 to be meshed with the first bevel gears 2364 on the two rotating shafts 232 respectively, and the drive motor 2367 uses the second bevel gear 2365 to drive the rotating shaft 232 to rotate.

[0057] Furthermore, the steering unit 235 includes a first steering component 2351 provided at the top of the reservoir 1, and a second steering component 2352 is provided at the bottom end of the inner wall of the reservoir 1.

[0058] Preferably, two structural designs of the first steering component 2351 are provided, and corresponding structural designs of the second steering component 2352 are given, as follows:

[0059] First, the first steering component 2351 includes a bogie provided on the reservoir 1, and a steering wheel rotatably engaged with the bogie and cooperating with the towing rope 234 is provided on the bogie; the structure of the second steering component 2352 is the same as that of the first steering component 2351.

[0060] Second, the first steering component 2351 includes a steering rod horizontally provided on the reservoir 1, connecting brackets connected to the reservoir 1 are provided at both ends of the steering rod, and a plurality of runner wheels cooperating with the towing rope 234 are provided on the steering rod; the structure of the second steering component 2352 is the same as that of the first steering component 2351.

[0061] Specifically, the bidirectional drive assembly 23 is one of the core parts of the entire sludge cleaning system. It is responsible for driving the scraper assembly 21 to move back and forth along the limit guide rod assembly 22. Through the coordinated work of key components such as the winding bracket 231 and the rotating shaft 232, the automatic back-and-forth movement of the scraper assembly 21 is realized.

[0062] In the structural design of this bidirectional drive assembly 23, the winding bracket 231 provides support and fixation to ensure that the rotating shaft 232 can be stably installed and rotated. The rotating shaft 232 is the core transmission component, which is rotated by motor drive, and then drives the drive roller 233 and the towing rope 234. The drive roller 233 is installed on the rotating shaft 232 and cooperates with the towing rope 234. The rotation of the rotating shaft 232 drives the winding and unwinding of the towing rope 234. The towing rope 234 connects the drive roller 233 and the scraper assembly 21, and the movement of the scraper assembly 21 is realized through the rotation of the drive roller 233.

[0063] In the steering unit 235 among them, the steering unit 235 guides the towing rope 234 to move along a predetermined path, ensuring that the towing rope 234 does not knot or tangle during movement. Components such as steering wheels or rotating wheels are designed to guide the towing rope 234 to move along a predetermined path. Through these wheels, the towing rope 234 can move smoothly without knotting or tangling.

[0064] In the drive unit 236 among them, the drive unit 236 consists of a drive motor 2367 and related transmission components. The engagement of the second bevel gear 2365 and the first bevel gear 2364 is controlled by an electric push rod 2366, thereby driving the rotation of the rotating shaft 232. The drive motor 2367 serves as the power source of the drive unit 236. The motor can convert electrical energy into mechanical energy to provide driving force for the entire system. The electric push rod 2366 is used to control the engagement state between the second bevel gear 2365 and the first bevel gear 2364. By changing the position of the electric push rod 2366, the second bevel gear 2365 can be brought into contact with or separated from the first bevel gear 2364, thus achieving the transmission or interruption of power. The first bevel gear 2364 and the second bevel gear 2365 are important links in the transmission chain, and they transmit torque through meshing with each other. The first bevel gear 2364 is usually fixed on the rotating shaft 232, and the second bevel gear 2365 can be engaged with the first bevel gear 2364 under the control of the electric push rod 2366. The rotating shaft 232 is the rotation center in the entire mechanical system. It rotates itself through the drive of the bevel gear and then drives other mechanical components connected to it to work, such as the scraper assembly 21.

[0065] Specifically, the drive unit 236 controls the engagement of the second bevel gear 2365 with the first bevel gear 2364 through the electric push rod 2366, thereby driving the rotation of the rotating shaft 232, solving the problem of how to control power transmission under different working conditions. Specifically, through the telescopic movement of the electric push rod 2366, it is possible to flexibly control whether the second bevel gear 2365 engages with the first bevel gear 2364, thereby realizing the opening or closing of power. This is particularly useful for mechanical equipment that needs to work intermittently or needs to start and stop frequently. At the same time, the use of the electric push rod 2366 can achieve precise power control, ensuring that sufficient torque is provided when needed, and the power supply is cut off in a timely manner when not needed, thereby improving work efficiency and reducing energy consumption. Moreover, due to the intervention of the electric push rod 2366, the engagement state of the bevel gears is easy to adjust, which is not only beneficial to daily maintenance but also convenient for quick repair when problems occur. This design ensures that the system can respond quickly when needed, and through the precise control of the electric push rod 2366, the efficiency and controllability of power transmission are achieved. This is very beneficial for mechanical systems that require precise control, especially for the sludge scraper used in sewage treatment facilities. Such a drive unit 236 can help achieve more efficient sludge cleaning work.

[0066] Furthermore, a protective cover frame for protecting the bidirectional drive assembly 23 is provided on the reservoir 1, and a protective cover plate is provided on the protective cover frame.

[0067] Specifically, the main function of the protective cover frame is to protect the bidirectional drive assembly 23, including the rotating shaft 232, the drive roller 233, the traction rope 234, etc., to prevent these key components from being damaged by external factors during operation, such as preventing the intrusion of dust, debris, moisture, etc., and preventing damage caused by possible mechanical collisions or human interventions. In the operating environment of the PP module reservoir 1, various external factors may affect the normal operation of the equipment, such as bad weather, accidental impacts, etc. The protective cover frame provides a physical barrier, effectively avoiding these potential risks and ensuring the stability and reliability of the system. The protective cover plate is a part of the protective cover frame and is usually designed as a detachable structure for maintenance and inspection. It directly covers the upper part of the drive assembly, providing an additional protective layer to prevent foreign objects from entering the system. The protective cover plate solves the protection problem during regular inspection and maintenance of the equipment, and at the same time facilitates the operation of maintenance personnel. Due to the detachable nature of the cover plate, it allows quick access to the internal components for necessary maintenance or replacement without disturbing the entire system.

[0068] Preferably, a traction groove matching with the traction rope 234 is formed on the pool wall of the reservoir 1.

[0069] Specifically, the traction groove is a groove formed on the pool wall of the water storage tank 1, which is used to guide the traction rope 234 to move along a predetermined path. This design ensures the stable operation of the traction rope 234, reduces friction and wear, and also protects the traction rope 234 from external factors. In the absence of a traction groove, the traction rope 234 may move disorderly on the pool wall, which not only increases wear but also may cause unstable operation of the scraper 211 mechanism. The design of the traction groove solves these problems and ensures the smooth and efficient operation of the traction rope 234 and the scraper assembly 21.

Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions, or substitutions made by those of ordinary skill in the art within the scope of the essence of the present utility model should also fall within the protection scope of the present utility model.
