[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5 As shown in the figure, a pipe dredging device for water supply and drainage according to an embodiment of the present invention includes a housing 1, a motor 11 fixedly connected to the side wall of the housing 1, and a drive gear 12 fixedly connected to the output end of the motor 11; a turntable 13 is provided between the housing 1 and the drive gear 12; a transmission gear 14 is rotatably connected to the side wall of the turntable 13, the three transmission gears 14 are arranged in a circumferential array, and the three transmission gears 14 are respectively meshed with the turntable 13; a gear cylinder 15 meshes with the side wall of the three transmission gears 14. A drive roller 16 is fixedly connected to the side wall of the toothed cylinder 15; a crushing disc 17 is provided at the end of the drive roller 16; crushing blocks 18 are provided on the side wall of the crushing disc 17, and multiple crushing blocks 18 are arranged in a circumferential array; a mud discharge trough 19 is opened on the side wall of the crushing disc 17, and multiple mud discharge troughs 19 are arranged corresponding to the positions of the crushing blocks 18; during operation, after the operator places the device inside the water supply and drainage pipe that needs to be dredged, the multiple crushing blocks 18 on the side wall of the crushing disc 17 can always be in contact with the silt. The crushing disc 17 is driven by a motor 11 to rotate the crushed blocks 18, thereby breaking down and removing the relatively hard sludge. During the process, whenever the motor 11, which is fixed to the side wall of the housing 1, is driven, the drive gear 12 will rotate. Since the drive gear 12 is meshed with the transmission gear 14 and the gear cylinder 15, and the turntable 13 is rotatably connected between the housing 1 and the gear cylinder 15, the gear cylinder 15 will rotate along with the rotation of the drive gear 12, and will drive the crushing disc 17 to rotate through the transmission roller 16. The sludge blocks crushed by multiple crushed blocks 18 can pass over the crushing disc 17 through the mud discharge chute 19. Through the above structure, the housing 1 drives the crushing disc 17 and its connected components to rotate, which damages the hard sludge. The planetary gear set composed of the drive gear 12, the turntable 13, and the transmission gear 14 transmits the power of the motor 11, enhances the torque of the crushing disc 17, improves the sludge crushing capacity of the device, and helps to solve the problem of hard sludge being difficult to clean.
[0026] like Figure 2 and Figure 4As shown, a fixing protrusion 2 is fixedly connected to the side wall of the crushing disc 17; a limiting groove 21 is formed on the side wall of the fixing protrusion 2, and multiple limiting grooves 21 are arranged in a circumferential array; a limiting cylinder 22 is fixedly connected to the end of the transmission roller 16, and the limiting cylinder 22 is set in a position corresponding to the size of the fixing protrusion 2; a limiting protrusion 23 is fixedly connected to the inner side wall of the fixing protrusion 2, and multiple limiting protrusions 23 are set in a position corresponding to the size of the limiting groove 21; a fixing screw 24 is threadedly connected between the fixing protrusion 2 and the limiting cylinder 22; during operation, the operator can use the correspondence between the limiting protrusion 23 and the limiting groove 21 to insert the limiting cylinder 22 into the side wall of the machine housing 1, and then the operator can use the fixing screw 24 to connect the fixing protrusion 2 and the limiting cylinder 2 The threaded connection of 2 allows the fixing screw 24 to be tightened between the fixing protrusion 2 and the limiting cylinder 22 until the side wall of the fixing screw 24 is in close contact with a predetermined position on the side wall of the crushing disc 17. Multiple limiting grooves 21 and multiple limiting protrusions 23 are in a one-to-one correspondence, and their contact makes the connection between the transmission roller 16 and the crushing disc 17 more stable. Through the above structure, the limiting grooves 21 and limiting protrusions 23 enhance the connection stability between the transmission roller 16 and the crushing disc 17, and the fixing screw 24 fixes the protrusion 2 and the limiting cylinder 22, thereby preventing them from falling off during operation. This helps reduce component shaking, improves the stability and durability of the device, and reduces component maintenance requirements.
[0027] like Figure 3 As shown, a fixing frame 3 is fixed to the side wall of the crushing disc 17, and multiple frames are arranged in a circumferential array. A sludge scraper 31 is provided on the inner side wall of the fixing frame 3. Fixing bolts 32 are provided between the fixing frame 3 and the sludge scraper 31, and multiple fixing bolts 32 are arranged in a corresponding manner. During operation, the operator can use the fixing bolts 32 to install multiple sludge scrapers 31 inside the corresponding fixing frame 3. Whenever the crushing disc 17 starts to rotate, the sludge scraper 31 can assist the crushing block 18 in breaking the silt. Whenever the sludge scraper 31 is damaged, the operator can remove the fixing bolts 32 and replace the sludge scraper 31. Through the above structure, the sludge scraper 31 is set to assist the crushing block 18 in breaking the silt, thereby solving the problem that the crushing block 18 cannot break the silt in the middle, improving the practicality of the device, and helping to improve the work efficiency of dredging operations in water supply and drainage pipelines.
[0028] like Figure 4As shown, movable rods 4 are slidably connected to the side wall of the casing 1, and multiple movable rods 4 are arranged correspondingly; wheel frames 41 are fixedly connected to the ends of the movable rods 4; rollers 42 are rotatably connected inside the wheel frames 41, and multiple rollers 42 are arranged correspondingly; buffer springs 43 are fixedly connected to the side wall of the wheel frames 41, and multiple buffer springs 43 are arranged corresponding to the positions of the movable rods 4; during operation, when the casing 1 is about to enter the pipeline, the operator can insert the multiple wheel frames 41 with the movable rods 4 fixedly connected to them into the side wall of the casing 1, so that the rollers 42 contact the inner side wall of the pipeline. At this time, because the multiple movable rods 4 are perpendicular to the casing 1, the rollers 42 are rotatably connected to the side wall of the pipeline. The sliding connection and the buffer spring 43 fixed to the side wall of the wheel frame 41 are in contact with the side wall of the housing 1. When the width of the inner wall of the pipe decreases, the wheel frame 41 and the roller 42 can shorten the distance between themselves and the housing 1 by compressing the buffer spring 43, thereby adapting to the change in the width of the inner wall of the pipe. Through the above structure, the wheel frame 41 and the roller 42 are set to contact the inner wall of the pipe to provide a limit for the device and prevent the device from tilting inside the pipe. The movable rod 4 and the buffer spring 43 are set to adjust the distance between the wheel frame 41, the roller 42 and the housing 1, which improves the flexibility and applicability of the device.
[0029] like Figure 2 As shown, a fixing panel 5 is fixedly connected to the side wall of the crushing disc 17, and multiple fixing panels 5 are arranged corresponding to the positions of the crushing blocks 18; screws 51 are threadedly connected between the fixing panels 5 and the crushing blocks 18, and multiple screws 51 are arranged in a corresponding manner; during operation, the operator can use the threaded connection between the screws 51 and the fixing panels 5 and the crushing blocks 18 to tighten the screws 51 between the fixing panels 5 and the crushing blocks 18, thereby fixing multiple crushing blocks 18 in a predetermined position; through the above structure, the fixing panels 5 and screws 51 are set so that the crushing blocks 18 are detachable and replaceable, which improves the flexibility of the device, helps to solve the problem of inconvenience in replacing the crushing blocks 18 after damage, and improves the practicality of the device.
[0030] like Figure 3 As shown, high-strength alloy blocks 6 are fixed to the sidewall of the crushing block 18, and multiple high-strength alloy blocks 6 are arranged in a corresponding manner. During operation, the multiple high-strength alloy blocks 6 fixed to the sidewall of the crushing block 18 can replace the crushing block 18 in contact with the sidewall of the hardened sludge. At this time, due to the higher structural strength of the high-strength alloy blocks 6, the crushing block 18 can maintain functional stability for a longer period of time. Through the above structure, the high-strength alloy blocks 6 enhance the structural strength of the cutting surface of the crushing block 18, which is beneficial to extending the service life of the device and reducing the maintenance requirements of the corresponding components of the device.
[0031] like Figures 1 to 3As shown, the crushing disc 17, crushing block 18, fixing frame 3, and scraper 31 are made of stainless steel. During operation, the stainless steel material of the crushing disc 17, crushing block 18, fixing frame 3, and scraper 31 can take advantage of the high structural strength and strong corrosion resistance of stainless steel. Through the above, the use of stainless steel material for the crushing disc 17, crushing block 18, fixing frame 3, and scraper 31 enhances the structural strength and corrosion resistance of the device, which is conducive to extending the service life of the device and reducing maintenance costs.
[0032] During operation, the device is placed inside the drainage pipe requiring dredging. Multiple crushing blocks 18 mounted on the sidewalls of the crushing disc 17 remain in constant contact with the silt. The crushing disc 17 is driven by the motor 11, causing the crushing blocks 18 to rotate, thus breaking down and removing the harder silt. During this process, whenever the motor 11, fixed to the sidewall of the housing 1, is driven, the drive gear 12 rotates. Since the drive gear 12 meshes with the transmission gear 14, and the transmission gear 14 meshes with the gear cylinder 15, and the turntable 13 is rotatably connected between the housing 1 and the gear cylinder 15, the gear cylinder 15 rotates along with the drive gear 12, driving the crushing disc 17 via the transmission roller 16. The sludge blocks, crushed by multiple crushing blocks 18, can pass over the crushing disc 17 via the sludge discharge chute 19. The operator can insert the limiting cylinder 22 into the side wall of the housing 1 using the correspondence between the limiting protrusion 23 and the limiting groove 21. Then, the operator can use the threaded connection between the fixing screw 24 and the fixing protrusion 2 and the limiting cylinder 22 to tighten the fixing screw 24 between the fixing protrusion 2 and the limiting cylinder 22 until the side wall of the fixing screw 24 is in close contact with a predetermined position on the side wall of the crushing disc 17. The multiple limiting grooves 21 and multiple limiting protrusions 23 are in a one-to-one correspondence, and their contact makes the connection between the drive roller 16 and the crushing disc 17 more stable. The operator can use the fixing bolts 32... Multiple scraper blades 31 are installed inside corresponding fixed frames 3. Whenever the crushing disc 17 starts to rotate, the scraper blades 31 can assist the crushing blocks 18 in breaking up the silt. Whenever a scraper blade 31 is damaged, the operator can remove the fixing bolts 32 to replace the scraper blade 31. When the machine box 1 is about to enter the pipeline, the operator can insert multiple wheel frames 41 with movable rods 4 fixed to them into the side wall of the machine box 1, so that the rollers 42 contact the inner side wall of the pipeline. At this time, since the multiple movable rods 4 are slidably connected to the machine box 1, and the buffer springs 43 fixed to the side wall of the wheel frames 41 are in contact with the side wall of the machine box 1, when the width of the inner wall of the pipeline decreases, the wheel frames 41 and the rollers 42 can compress the buffer springs. The spring 43 shortens the distance between itself and the casing 1, thereby adapting to the changes in the width of the inner wall of the pipe. The operator can use the screw 51 to tighten the screw between the fixed panel 5 and the crushing block 18 through the threaded connection between the screw 51 and the fixed panel 5 and the crushing block 18, thereby fixing multiple crushing blocks 18 in a predetermined position. Multiple high-strength alloy blocks 6 fixed to the side wall of the crushing block 18 can replace the crushing block 18 in contact with the side wall of the hard sludge. At this time, due to the higher structural strength of the high-strength alloy block 6, the crushing block 18 can maintain functional stability for a longer period of time. The crushing disc 17, crushing block 18, fixed frame 3, and sludge scraper 31 made of stainless steel can take advantage of the high structural strength and strong corrosion resistance of stainless steel.
