Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline dredging technology, and in particular to sewage dredging equipment for water conservancy pipelines. Background Technology

[0002] For example, Chinese patent CN222575728U discloses a stormwater and sewage pipe network dredging device. By setting up a cleaning unit, the telescopic component 2 is activated to push the disc to move. The disc pushes the connecting block to rotate around the disc and the scraper. At the same time, the scraper is pushed to expand along the limiting rod 2 until the scraper contacts the inner wall of the pipe, thereby facilitating the cleaning of the inner wall of different stormwater and sewage pipe networks.

[0003] However, this solution has obvious limitations: First, the dredging range is limited by the travel of the telescopic boom, which can only clean short-distance pipelines. When facing long-distance main pipelines in cities (often exceeding 50 meters), it cannot reach deep into the pipeline and requires frequent segmented construction, resulting in low efficiency. Second, relying solely on mechanical scraping with scrapers is not enough to thoroughly clean stubborn deposits such as oil stains and hardened sludge adhering to the inner wall. Residual deposits are prone to re-clogging, resulting in poor cleaning effect. Third, there is a lack of a structure for real-time discharge of deposits. The accumulation of deposits will affect the depth of the telescopic boom and further limit the dredging range of a single operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sewage dredging device for water conservancy pipelines. It solves the technical problems of existing dredging equipment having a limited cleaning range, relying solely on scrapers for cleaning, making it difficult to remove stubborn silt, resulting in poor cleaning effects, requiring frequent segmented construction, low efficiency, and the inability to discharge the cleaned silt in real time. The device achieves the goal of increasing the cleaning range per session, improving the cleaning effect, removing silt, and improving dredging efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sewage dredging equipment for water conservancy pipelines, including a dredging vehicle. Electric lifting rods for adjusting the height of the dredging equipment are symmetrically installed on both sides of the top of the dredging vehicle. An installation plate is fixedly connected to the top of the electric lifting rod, and a bearing seat is fixedly connected to the top of the installation plate. A rotating shaft is rotatably connected inside the bearing seat. A rotating assembly for driving the rotating shaft is provided on the installation plate. A turntable is fixedly connected to the end of the rotating shaft. An electric telescopic rod is installed in the mounting groove on the side of the turntable. A dredging brush for cleaning the inner wall of the pipeline is fixedly connected to the free end of the electric telescopic rod. A flushing assembly for rinsing and removing dirt from the inner wall of the pipeline is provided on the rotating shaft. A dredging assembly for real-time sewage discharge is provided on the dredging vehicle.

[0006] A further improvement is that the sludge removal brush plate has a stepped structure with the left side lower and the right side higher. The lower steps are equipped with cleaning bristles to form a brushing section, while the higher steps are a scraping section.

[0007] A further improvement is that the flushing assembly includes a water inlet hole opened in the rotating shaft, and a bearing connected to a water pipe is provided at the port of the water inlet hole. A diversion cavity communicating with the water inlet hole is opened in a ring array inside the turntable. High-pressure nozzles communicating with the diversion cavity are arranged in an array on the turntable, and the high-pressure nozzles are inclined towards the pipe wall.

[0008] A further improvement is that the dredging component includes a sliding sleeve fixed to the dredging vehicle, a compressible rubber airbag installed inside the sliding sleeve, an exhaust hole on the side of the rubber airbag, a base fixed to the bottom of the rubber airbag, a dredging connector that can be connected to the sludge suction pipe fixed to the base, and an elastic metal sheet installed on the outer side of the rubber airbag.

[0009] A further improvement is that the rotating assembly includes a gear ring fixed to the rotating shaft, a gear meshing with the side of the gear ring, and a motor for driving the gear to rotate is mounted on the mounting plate.

[0010] A further improvement is that an electronic control system component with a counterweight and control is installed on one side of the top of the dredging vehicle. All the electrical components are electrically connected to the electronic control system component through waterproof wires, and both the electrical components and the electronic control system component are waterproof and corrosion-resistant.

[0011] By employing the above technical solution, this utility model provides a sewage dredging device for water conservancy pipelines, which has at least the following beneficial effects: 1. This utility model involves synchronously activating an electric telescopic rod, extending its free end until the cleaning brush plate on it adheres to the inner wall of the pipe, and then activating the rotating assembly to drive the rotating shaft to rotate, thereby driving the turntable and the cleaning brush plate on it to rotate and clean the pipe wall. The bristles on the cleaning brush plate achieve deep cleaning of the stains on the pipe wall, and the scraping part scrapes off the cleaned sludge, thereby improving the cleaning effect and adapting to the cleaning work of pipes of different diameters.

[0012] 2. This utility model pumps clean water from the outside into the diversion chamber through a water pipe connected to the bearing on the water inlet hole, until it is sprayed out from the inclined high-pressure nozzle, thereby spraying the high-pressure water flow onto the pipe wall. In conjunction with the rotating turntable, the high-pressure water flow washes off the sludge and other dirt adhering to the pipe wall in advance, avoiding the brush bristles on the cleaning brush plate from directly contacting a large amount of sludge and affecting its cleaning effect.

[0013] 3. This utility model uses a rubber airbag to gather the sludge at the bottom of the pipe, and then connects the sewage pipe to the sludge removal connector, thereby pumping out the sludge accumulated at the bottom of the pipe. This makes it easier for the sludge removal vehicle to penetrate the pipe, increases the cleaning range per operation, and thus improves the sludge removal efficiency. Attached Figure Description

[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] Example 1 Given the limitations of existing dredging equipment—its limited cleaning range, reliance on scrapers for removing stubborn silt, poor cleaning effect, need for frequent segmented operations leading to low efficiency, and inability to discharge cleaned silt in real time—this embodiment provides a sewage dredging device for water conservancy pipelines. This device increases the cleaning range per operation, improves cleaning effectiveness, effectively removes silt, and enhances dredging efficiency. Please refer to... Figures 1-5The sewage dredging equipment for the water conservancy pipeline network includes a dredging vehicle 1. Electric lifting rods 2, symmetrically mounted on both sides of the top of the dredging vehicle 1, are used to adjust the height of the dredging equipment. A mounting plate 3 is fixed to the top of the electric lifting rods 2, and a bearing seat 4 is fixed to the top of the mounting plate 3. A rotating shaft 5 is rotatably connected inside the bearing seat 4. A rotating assembly 6, which drives the rotating shaft 5, is mounted on the mounting plate 3. A turntable 7 is fixed to the end of the rotating shaft 5. An electric telescopic rod 8 is installed in a mounting groove on the side of the turntable 7. A dredging brush 9, used for cleaning the inner wall of the pipe, is fixed to the free end of the electric telescopic rod 8. A flushing assembly 10, used for flushing and removing dirt from the inner wall of the pipe, is mounted on the rotating shaft 5. A dredging assembly 11, used for real-time sewage discharge, is mounted on the dredging vehicle 1. When dealing with pipes of different diameters, the electric telescopic rod 8 is simultaneously activated by the electrical control system assembly 12, allowing it to move freely... The cleaning brush 9 extends to the end of the pipe until it fits against the inner wall of the pipe, thus adapting to the cleaning work of pipes with different diameters. Then, the electric lifting rod 2 is activated to push the cleaning vehicle 1 in the opposite direction until it contacts the pipe wall, so that the cleaning vehicle 1 can drive normally into the pipe. Then, the clean water pipe is connected to the flushing component 10, so that the high-pressure water jet sprays out to wash and wet the stains on the inner wall of the pipe. Then, the rotating component 6 is activated to drive the rotating shaft 5 to rotate, which in turn drives the turntable 7 and the cleaning brush 9 on it to rotate to scrub and clean the pipe wall, improving the cleaning effect. The cleaned sludge accumulates at the bottom of the pipe. Then, the sludge suction pipe is connected to the cleaning component 11 to remove the sludge in real time. Together with the cleaning vehicle 1, which carries the cleaning equipment into the pipe, it can reach deep into the pipe and increase the cleaning range of a single operation.

[0019] Specifically, the sludge cleaning brush plate 9 has a stepped structure with a lower left side and a higher right side. The lower steps are equipped with cleaning bristles to form the brushing section, while the higher steps are the scraping section. The brush bristles on the sludge cleaning brush plate 9 are used to deeply clean the stains on the pipe wall after soaking, and the scraping section scrapes off the cleaned sludge, thereby improving the cleaning effect.

[0020] Since relying solely on the cleaning brush 9 to dry-brush the pipe wall stains has a weak cleaning effect, and a large amount of sludge will quickly contaminate the bristles on the cleaning brush 9, affecting the cleaning effect, the flushing assembly 10 includes a water inlet 101 opened in the rotating shaft 5, and a bearing connected to a water pipe is provided at the port of the water inlet 101. The turntable 7 has a ring array of diversion chambers 102 communicating with the water inlet 101. High-pressure nozzles 103 communicating with the diversion chambers 102 are arrayed on the turntable 7, and the high-pressure nozzles 103 are inclined towards the pipe wall. Clean water from the outside is pumped into the diversion chamber 102 through the water pipe connected to the bearing on the water inlet 101 until it is sprayed out from the inclined high-pressure nozzles 103, thereby spraying high-pressure water towards the pipe wall. In conjunction with the rotating turntable 7, the high-pressure water flow washes off the sludge and other contaminants adhering to the pipe wall in advance, avoiding direct contact between the bristles on the cleaning brush 9 and a large amount of sludge, which would affect its cleaning effect.

[0021] Specifically, the rotating assembly 6 includes a gear ring 61 fixed to the rotating shaft 5, a gear 62 meshing with the side of the gear ring 61, and a motor 63 that drives the gear 62 to rotate on the mounting plate 3. When the motor 63 is started, it drives the gear 62 to rotate, which in turn drives the gear ring 61 meshing with it to rotate the rotating shaft 5, thereby driving the cleaning brush plate 9 on the turntable 7 to rotate and clean the sludge on the pipe wall.

[0022] Specifically, an electronic control system component 12 with counterweight and control is installed on one side of the top of the dredging vehicle 1. All the above electrical components are electrically connected to the electronic control system component 12 through waterproof wires, and both the above electrical components and the electronic control system component 12 are waterproof and corrosion-resistant. The dredging equipment on the dredging vehicle 1 is controlled to operate normally by the electronic control system component 12 in conjunction with an external remote control.

[0023] Example 2 Because the sludge removed accumulates at the bottom of the pipe, affecting the depth of the sludge removal vehicle 1 and thus the cleaning efficiency, therefore, based on Example 1, as follows... Figures 1-5 As shown, the sludge removal assembly 11 includes a sliding sleeve 111 fixed to the sludge removal vehicle 1. A compressible rubber airbag 112 is installed inside the sliding sleeve 111. An exhaust port 113 is provided on the side of the rubber airbag 112. A base 114 is fixed to the bottom of the rubber airbag 112, and a sludge removal connector 115, which can be connected to a sewage suction pipe, is fixed to the base 114. An elastic metal sheet 116 is installed on the outer side of the rubber airbag 112. Connecting the sewage pipe to the sludge removal connector 115 allows the sludge accumulated at the bottom of the pipe to be pumped out, making it easier for the sludge removal vehicle 1 to penetrate deeper into the pipe, increasing the cleaning range per cycle, and thus improving sludge removal efficiency. Furthermore, when facing smaller diameter pipes, the inner wall of the pipe will exert reverse pressure on the elastic metal sheet. The elastic metal sheet 116 retracts and compresses the rubber airbag 112, allowing the gas inside the rubber airbag 112 to be discharged through the exhaust port 113. This enables the rubber airbag 112 to be adapted to pipes with smaller diameters, improving the applicability of the device. The elastic metal sheet 116 also prevents the outer side of the rubber airbag 112 from directly rubbing against it, extending its service life. The rubber airbag 112 uses synthetic fiber fabric as a pressure-resistant and load-bearing skeleton, and is filled with vulcanized synthetic wear-resistant and corrosion-resistant rubber inside and out, forming a semi-circular plate-like structure. While collecting sludge, it can also be compressed and rebounded to a certain extent, thus adapting to pipes of different diameters.
