Description

Technical Field

[0001] This application relates to the field of sewer cleaning device technology, specifically a sewer cleaning device. Background Technology

[0002] A sewer system is a type of urban public facility, referring to the pipes through which buildings discharge sewage and rainwater; it also refers to the underground channels through which sewage and rainwater are discharged in cities, factories, or villages. A sewer cleaner is a tool used to unclog sewers. Over time, impurities and hair accumulate on the inner walls of sewer pipes, eventually causing blockages. If these blockages are not cleaned promptly, they can disrupt residents' daily lives. Therefore, a sewer cleaner is urgently needed to quickly unclog different types of sewer pipes.

[0003] An existing patent (publication number: CN218466645U) discloses a sewer unclogger, relating to the field of sewer unclog technology. Addressing the problems of existing sewer uncloggers requiring manual and repeated rotation of the spring drill bit, increasing labor intensity, and hindering quick replacement of the spring drill bit, resulting in poor performance, this invention proposes the following solution: A housing is included, with a U-shaped plate fixedly mounted on its bottom side. A fixed cylinder is fixedly connected to the bottom side of the U-shaped plate, and a disassembly cylinder is threadedly connected to the inner wall of the fixed cylinder. A motor is fixedly installed inside the housing, and a positioning box is welded to the output shaft of the motor. This invention has a reasonable structural design, is simple to operate, and only requires starting the motor to rotate the spring drill bit, reducing operator workload, facilitating spring drill bit replacement, and providing good performance.

[0004] The above solution utilizes the worm gear, worm wheel, and threaded rod in the positioning box, along with the L-shaped clamping rod, to achieve quick assembly and disassembly of the spring drill bit. However, during the transmission process using the worm gear and worm wheel, there is a relatively large sliding between the tooth surfaces, resulting in significant frictional loss. In high-power transmission scenarios, this will cause more energy loss and increase operating costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a sewer dredging device that has the advantages of quick assembly and disassembly of spring drill bits, thus solving the problem of high operating costs in existing technologies.

[0006] To achieve the above objectives, this application provides the following technical solution: a sewer cleaner, comprising a housing, a motor fixedly installed on the inner wall of the housing, a connecting column fixedly connected to the output end of the motor, a connecting rod slidably connected to the inner wall of the connecting column, a spring body fixedly connected to the inner wall of the connecting column, one end of the spring body near the connecting rod being fixedly connected to the connecting rod, a connector being rotatably connected to the outer surface of the connecting column, a slot being formed on the outer surface of the connecting rod, the inner wall of the slot being rotatably connected to the connector, and two support rods being fixedly connected to the outer surface of the connector.

[0007] The above solution uses high-strength engineering plastic material for the housing, which has good impact resistance and corrosion resistance, and can work stably in humid and complex sewer environments. The connecting column, as the key hub for power transmission, has an ingenious internal design. A sliding track adapted to the connecting rod is set on the inner wall of the connecting column, which allows the connecting rod to slide smoothly in a straight line within the connecting column. The connecting rod can also rotate synchronously with the connecting column. When the motor starts, it will drive the connecting rod to rotate simultaneously through the connecting column. The support rods are symmetrically distributed. During this process, the connecting column and the connecting rod will rotate relative to each other within the connector.

[0008] Furthermore, the outer surface of each of the support rods is slidably connected to the housing, and a push block is fixedly connected to the ends of the two support rods that are far apart from each other.

[0009] With the above solution, by pushing the push block, the push block will push the connecting rod through the corresponding support rod, causing it to slide horizontally along the connecting column. The outer surface of each support rod is designed with a slide rail structure that precisely matches the inner wall of the housing. At the same time, the slide rail adopts a dustproof and sealed design to effectively prevent dirt and silt from the sewer from entering the sliding gap, ensuring the reliability of long-term use.

[0010] Furthermore, the outer surface of each pusher is slidably connected to the housing, and an overload protection component is fixedly installed on the upper surface of the housing.

[0011] With the above solution, when the protection mechanism is triggered, the overload protection component will emit alarm sounds of different frequencies to facilitate quick troubleshooting. The sliding connection between the push block and the housing makes the movement of the push block smoother, making it easier for the user to push the push block to move the connecting rod so that it slides horizontally along the connecting column.

[0012] Furthermore, a heat dissipation frame is provided on the outer side of the housing, and four elastic plates are fixedly connected to the outer surface of the heat dissipation frame.

[0013] Through the above solution, when the motor is working, the heat sink can quickly conduct heat to the surrounding air, thereby reducing the motor temperature and effectively extending the motor life. The elastic plate is made of beryllium bronze alloy, which has good elasticity and fatigue resistance. The inner side of each elastic plate is designed with wavy anti-slip teeth to improve friction.

[0014] Furthermore, four triangular clamping plates are fixedly connected to the outer surface of the housing, and the outer surface of each triangular clamping plate is engaged with a corresponding elastic clamping plate.

[0015] Through the above scheme, the four triangular plates and the four elastic plates on the outer surface of the heat sink frame form a precise snap-fit. The inner side of the elastic plate has a trapezoidal slot that matches the shape of the trapezoidal tongue of the triangular plate. The inner wall is provided with serrated anti-slip texture. When the elastic plate and the triangular plate are snapped together, the serrated texture can be tightly engaged to ensure a stable connection between the heat sink frame and the shell.

[0016] Furthermore, a mounting bracket is inserted into the side of the housing away from the heat sink, and a fixing plate is fixedly connected to the outer surface of the mounting bracket.

[0017] Through the above solution, the sewer cleaner can be flexibly expanded in function by using the design of the mounting bracket and fixing plate. Users can quickly install the required accessories according to the actual dredging scenario, improving the efficiency and convenience of dredging operations. The mounting bracket can be quickly installed on the housing using fixing bolts.

[0018] Furthermore, a T-shaped plate is slidably connected to the inner wall of the fixed plate, a connecting block is rotatably connected to the inner wall of the T-shaped plate, and a spring drill bit is fixedly connected to the side of the connecting block away from the T-shaped plate.

[0019] With the above scheme, the fixed plate is equipped with two parallel dovetail groove slide rails, which form a high-precision sliding fit with the dovetail sliders on both sides of the T-shaped plate, ensuring that the T-shaped plate can achieve smooth and stable linear sliding within the fixed plate. During the installation of the T-shaped plate, the push block needs to be pushed to drive the fixing head into the housing. At this time, the spring body will be compressed. Then, the T-shaped plate is installed in the fixed plate, and the spring body will push the fixing head into the connecting block under its rebound force.

[0020] Furthermore, a fixing head is fixedly connected to the outer surface of the connecting rod, and the outer surface of the fixing head is inserted into the connecting block.

[0021] With the above method, after the fixed head and the connecting block are inserted, the motor will start and drive the spring drill bit to rotate, which can quickly unclog the sewer.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This type of sewer cleaner, by pushing the push block, causes the connecting rod to slide horizontally along the connecting column through the connector head. Then the spring body is compressed, and the T-shaped plate with the connecting block is vertically inserted along the fixing plate until the connecting block and the fixing head are on the same central axis. Then the push block is released, and the spring body will push the fixing head into the connecting block under its elastic force. This allows for faster and more convenient assembly and disassembly of the spring drill bit. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 4 and Figure 5A sewer cleaner according to this embodiment includes a housing 1. A motor 6 is fixedly installed on the inner wall of the housing 1. A connecting post 7 is fixedly connected to the output end of the motor 6. A connecting rod 9 is slidably connected to the inner wall of the connecting post 7. A spring body 8 is fixedly connected to the inner wall of the connecting post 7. The end of the spring body 8 near the connecting rod 9 is fixedly connected to the connecting rod 9. A connector 11 is rotatably connected to the outer surface of the connecting post 7. A slot 10 is opened on the outer surface of the connecting rod 9. The inner wall of the slot 10 is rotatably connected to the connector 11. Two support rods 12 are fixedly connected to the outer surface of the connector 11.

[0033] Please see Figure 3 , Figure 4 and Figure 5 Each support rod 12 has its outer surface slidably connected to the housing 1. Each of the two support rods 12 has a push block 13 fixedly connected to its opposite end. By pushing the push block 13, the push block 13 will push the connecting rod 9 through the corresponding support rod 12, causing it to slide horizontally along the connecting column 7. The outer surface of each support rod 12 is designed with a slide rail structure that precisely matches the inner wall of the housing 1. At the same time, the slide rail adopts a dustproof and sealed design to effectively prevent dirt and silt from the sewer from entering the sliding gap, ensuring the reliability of long-term use.

[0034] Please see Figure 1 , Figure 2 and Figure 3 Each push block 13 has its outer surface slidably connected to the housing 1. An overload protection component 3 is fixedly installed on the upper surface of the housing 1. When the protection mechanism is triggered, an alarm sound of different frequencies is emitted through the overload protection component 3, which facilitates quick troubleshooting. The sliding connection between the push block 13 and the housing 1 makes the movement of the push block 13 smoother, making it easier for the user to push the push block 13 to move the connecting rod 9 so that it slides horizontally along the connecting column 7.

[0035] Please see Figure 1 , Figure 2 The outer side of the housing 1 is provided with a heat sink 4. Four elastic plates 5 are fixedly connected to the outer surface of the heat sink 4. When the motor 6 is working, the heat sink 4 can quickly conduct heat to the surrounding air, thereby reducing the temperature of the motor 6 and effectively extending the life of the motor 6. The elastic plates 5 are made of beryllium bronze alloy, which has good elasticity and fatigue resistance. The inner side of each elastic plate 5 is designed with wave-shaped anti-slip teeth to improve friction.

[0036] Please see Figure 2Four triangular clips 2 are fixedly connected to the outer surface of the housing 1. The outer surface of each triangular clip 2 is engaged with the corresponding elastic clip 5. The four triangular clips 2 and the four elastic clips 5 on the outer surface of the heat sink 4 form a precise engagement. The inner side of the elastic clip 5 has a trapezoidal groove that matches the shape of the trapezoidal tongue of the triangular clip 2. The inner wall is provided with serrated anti-slip texture. When the elastic clip 5 is engaged with the triangular clip 2, the serrated texture can be tightly engaged to ensure that the heat sink 4 is firmly connected to the housing 1.

[0037] Please see Figure 2 , Figure 3 and Figure 4 A mounting bracket 15 is inserted into the side of the housing 1 away from the heat sink 4. A fixing plate 16 is fixedly connected to the outer surface of the mounting bracket 15. Through the design of the mounting bracket 15 and the fixing plate 16, the sewer cleaner can flexibly expand its functions. Users can quickly install the required accessories according to the actual dredging scenario, thereby improving the efficiency and convenience of dredging operations. The mounting bracket 15 can be quickly installed on the housing 1 using fixing bolts.

[0038] Please see Figure 3 , Figure 4 and Figure 5 The inner wall of the fixed plate 16 is slidably connected to a T-shaped plate 17, and the inner wall of the T-shaped plate 17 is rotatably connected to a connecting block 18. A spring drill bit 19 is fixedly connected to the side of the connecting block 18 away from the T-shaped plate 17. The fixed plate 16 is provided with two parallel dovetail groove slide rails, which form a high-precision sliding fit with the dovetail sliders on both sides of the T-shaped plate 17 to ensure that the T-shaped plate 17 can achieve smooth and stable linear sliding within the fixed plate 16. During the installation of the T-shaped plate 17, the push block 13 needs to be pushed to drive the fixing head 14 to slide into the housing 1. At this time, the spring body 8 will be compressed. Then, the T-shaped plate 17 is installed in the fixed plate 16. Under the action of its rebound force, the spring body 8 will push the fixing head 14 to insert into the connecting block 18.

[0039] Please see Figure 4 , Figure 5 A fixing head 14 is fixedly connected to the outer surface of the connecting rod 9. The outer surface of the fixing head 14 is inserted into the connecting block 18. When the fixing head 14 is inserted into the connecting block 18, the motor 6 will start and drive the spring drill bit 19 to rotate, so as to quickly unclog the sewer.

[0040] In this embodiment, a drain cleaner works by pushing the push block 13, which causes the connecting rod 9 to slide horizontally along the connecting post 7 via the connector 11. Then, the spring body 8 is compressed, and the T-shaped plate 17 with the connecting block 18 is vertically inserted along the fixing plate 16 until the connecting block 18 and the fixing head 14 are on the same central axis. Then, the push block 13 is released, and the spring body 8 pushes the fixing head 14 into the connecting block 18 under its rebound force. This allows for faster and more convenient assembly and disassembly of the spring drill bit 19.

[0041] The working principle of the above embodiments is as follows:

[0042] First, insert the heat sink 4 horizontally along the housing 1. During this process, the heat sink 4 can be quickly installed on the housing 1 by the snap-fit ​​between the elastic plate 5 and the corresponding triangular plate 2. Then, the mounting bracket 15 can be installed on the housing 1 by using the fixing bolts. At this time, the fixing head 14 will pass through the mounting bracket 15. Then push the push block 13. The push block 13 will drive the connecting rod 9 through the connecting head 11 to slide horizontally along the connecting column 7. At this time, the spring body 8 will be compressed. Then, the T-shaped plate 17 with the spring drill bit 19 will be vertically inserted along the fixing plate 16 until the connecting block 18 and the fixing head 14 are on the same central axis. At this time, release the push block 13. The spring body 8 will push the connecting rod 9 into the connecting block 18 under its rebound force. Then, by starting the motor 6, the motor 6 will drive the spring drill bit 19 to unclog the sewer.
