Description

Technical Field

[0001] This invention relates to the field of drainage pipe cleaning and dredging technology, specifically a device for cleaning and dredging building drainage risers. Background Technology

[0002] With economic and social development, the existing building drainage systems, especially drainage risers, have been in operation for a long time (decades). Oil stains and other debris generated in daily life adhere to the inner wall of the drainage pipes, causing the effective drainage inner diameter of the drainage pipes to gradually decrease, affecting the drainage effect. At the same time, in the lower floors of buildings, drainage risers are prone to blockage caused by the accumulation of solid waste (which may even be very hard blockages). All of these factors affect people's daily lives.

[0003] There are many conventional methods for cleaning and unblocking pipes, including chemical reagent methods, high-pressure flushing methods, and pipe robots. However, building drainage risers have their own special characteristics: small pipe diameter, large vertical height, and inspection ports distributed on various floors. Traditional cleaning and unblocking methods have limited effectiveness and are difficult to operate in practice. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a building drainage riser cleaning and dredging device to solve the above-mentioned problems.

[0005] The objective of this invention is achieved through the following technical solution: a building drainage riser cleaning and unblocking device, comprising a cleaning and unblocking body, a lifting controller for controlling the raising and lowering of the cleaning and unblocking body, and a camera for observing the inside of the riser. The side wall of the cleaning and unblocking body is provided with multiple water outlets, a water pipe is connected to the cleaning and unblocking body, and a blade is provided on the lower side of the cleaning and unblocking body.

[0006] The lifting controller includes a bracket and a lifting body mounted on the bracket. The lifting body is connected to the cleaning and unblocking body by a steel wire rope.

[0007] The cleaning and unblocking body consists of a first cleaning and unblocking body and a second cleaning and unblocking body. The first cleaning and unblocking body and the second cleaning and unblocking body are connected by a ball joint. The water outlet is set on the first and second cleaning and unblocking bodies. The blade is connected to the second cleaning and unblocking body.

[0008] The cleaning and unblocking body is rotatably provided with side support rods on both sides, and a roller is provided at the end of the side support rod away from the cleaning and unblocking body. A first return spring is provided between the side support rod and the cleaning and unblocking body, with both ends connected to the two.

[0009] The cleaning and unblocking body is provided with support components on both sides. The support components include hydraulic rods, and a support plate is provided at the end of the hydraulic rods away from the cleaning and unblocking body.

[0010] The outer wall of the cleaning and dredging body is provided with a water outlet ring, and multiple water outlets are provided on the water outlet ring.

[0011] It also includes an automated control panel for controlling the cleaning and unblocking of the main body.

[0012] The tool includes a cutter head support. When the tool is a sidewall cutting tool, multiple nylon ropes are provided on the outer wall of the cutter head support. When the tool is a front-end cutting tool, multiple triangular serrated unblocking parts are provided on the side of the cutter head support away from the cleaning and unblocking body.

[0013] A waterway is provided between the multiple water outlets and water pipes, and an impeller is provided in the waterway to generate negative pressure. A motor and a second planetary gear set are provided in the cleaning and unblocking body. The second planetary gear set has one input end and two output ends. The motor is connected to the input end of the second planetary gear set, and the two output ends of the second planetary gear set are respectively connected to the impeller and the cutter drive.

[0014] The lifting controller is mounted on the cleaning and unblocking body. A first planetary gear set is provided between the motor and the second planetary gear set. The first planetary gear set has one input end and two output ends. The input end is connected to the motor, and the two output ends are respectively connected to the lifting controller and the input end of the second planetary gear set. It also includes a switching component for controlling whether the output end of the first planetary gear set outputs.

[0015] The beneficial effects of this invention are:

[0016] (1) Cleaning and dredging are achieved by cleaning and dredging the body, and the display and operation are carried out through the automated operating console. The robot's rise and fall are controlled by the lifting controller, and the starting of the blades, cleaning water flow, and hydraulic rods are all controlled through the automated operating console. No manual operation is required, which has the characteristics of automation.

[0017] (2) The cleaning and unblocking body is equipped with side wall cutting tools and front cutting tools to meet the needs of different application scenarios.

[0018] (3) It is equipped with multiple cameras, which can monitor the situation inside the pipe in real time. At the same time, it can also monitor the cutting effect of the front end and the side wall shearing in real time, so as to adjust the parameters of the cutter head rotation, water pressure and hydraulic rod support force in real time, so as to achieve better cleaning and dredging effect, and has the characteristics of intelligence.

[0019] (4) The operation of the tool and the high-pressure water spray is realized by a motor through the second planetary gear set, without the need to set up a separate drive source for the tool and the high-pressure water spray.

[0020] (5) With the first planetary gear set and the second planetary gear set, only one motor is needed to realize the operation of the cleaning and unblocking body rising, falling, cutting, spraying water, etc., and by switching components, different modes of movement and operation of the cleaning and unblocking body can be switched, which is very convenient.

Detailed Implementation

[0034] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0036] A device for cleaning and unblocking building drainage risers, reference Figure 1 and Figure 2 The system includes a cleaning and unblocking body 1. In this embodiment, the cleaning and unblocking body 1 is composed of a first cleaning and unblocking body 101 and a second cleaning and unblocking body 102 connected by a ball joint 103.

[0037] Both the first cleaning and unblocking body 101 and the second cleaning and unblocking body 102 are fitted with water outlet rings 402. The water outlet rings 402 are rotatably mounted on the first cleaning and unblocking body 101 and the second cleaning and unblocking body 102. Six water outlets 401 are evenly arranged on the water outlet rings 402. The first cleaning and unblocking body 101 and the second cleaning and unblocking body 102 are connected by a water pipe 403. The water pipe 403 is connected to a water tank 4. In this embodiment, the water tank 4 is a high-pressure water tank, which contains a high-pressure pump. The high-pressure pump can send water from the water tank to the first cleaning and unblocking body 101 and the second cleaning and unblocking body 102, from which it is sprayed out from the water outlets 401.

[0038] The lower end of the second cleaning and unblocking body 102 is detachably and rotatably equipped with a blade 6. (Reference) Figure 3 and Figure 4 The cutting tool 6 can be a sidewall-cutting type or a front-end-cutting type. The sidewall-cutting type includes a cutter head support 601, with multiple nylon ropes 602 evenly arranged on the sidewall of the cutter head support 601. The front-end-cutting type includes a cutter head support 601, with multiple triangular serrated unblocking parts 603 evenly arranged on the front side of the cutter head support 601. The sidewall-cutting type cutter cuts away the deposits on the sidewall of the drainage riser 14, while the front-end-cutting type unblocks the blockage 13 at the front end of the drainage riser 14. The appropriate cutting tool 6 can be used as needed.

[0039] Multiple support components 8 are evenly arranged around the periphery of both the first cleaning and unblocking body 101 and the second cleaning and unblocking body 102. In this embodiment, the support component 8 consists of a hydraulic rod 801 and a support plate 802 disposed at the end of the hydraulic rod 801. When the cutter 6 is working, the support component 8 can be braced against the side wall of the drainage riser 14 to provide sufficient support force, and the magnitude of the support force can be adjusted according to actual needs. Multiple side support rods 701 are evenly rotatably arranged on both the first cleaning and unblocking body 101 and the second cleaning and unblocking body 102. A roller 702 is provided at the upper end of the side support rod 701. A first return spring 703 is provided between the upper side of the side support rod 701 and the cleaning and unblocking body 1, with both ends connected to the two. The first return spring 703 ensures that the roller 702 always abuts against the side wall of the drainage riser 14, and that the first cleaning and unblocking body 101 and the second cleaning and unblocking body 102 are always located at the center of the drainage riser 14. A camera 3 is provided at the center of the front end of the cutter 6 and on the side wall of the cleaning and unblocking body 1.

[0040] The upper end of the first cleaning and dredging body 101 is connected to the lifting body 202 via a steel wire rope 203. The lifting body 202 is mounted on the support 201. The lifting body 202 is similar in structure to existing hoists, and since it is existing technology, it will not be described in detail here.

[0041] The cleaning and unblocking body 1 is electrically connected to the automated control panel 12. The automated control panel 12 is also electrically connected to the water tank 4 and the lifting controller 2. Thus, the operator can control the raising, lowering, water spraying, and cleaning and unblocking operations of the cleaning and unblocking body 1 through the automated control panel 12.

[0042] As a further improvement to the present invention, various novel embodiments can be provided based on the above examples.

[0043] As a second embodiment of the present invention, based on embodiment 1, and referring to... Figure 5 and Figure 6 The cleaning and unblocking body 1 is a single unit. A water channel 404 is installed inside the cleaning and unblocking body 1. The water channel 404 is connected to the water outlet ring 402 and the water pipe 403. An impeller 405 for generating negative pressure is rotatably installed inside the water channel 404.

[0044] The cleaning and unblocking body 1 contains a motor 5. The output of motor 5 is connected to a second planetary gear set 9. The second planetary gear set 9 consists of a sun gear 1002, three planetary gears 1004, and a ring gear 1003. Since planetary gear sets are a well-known mechanical structure, they will not be described in detail here. In the second planetary gear set 9, each of the three planetary gears 1004 near the motor 5 has a secondary gear 902 connected in series. The secondary gears 902 are fixed in position. The three secondary gears 902 mesh around a central gear 901. The output of motor 5 is connected to the central gear 901.

[0045] In the second planetary gear set 9, a water-spraying gear 407 meshes with the outer wall of the gear ring 1003. The water-spraying gear 407 is connected to the impeller 405 via a water-spraying transmission rod 406. In the second planetary gear set 9, the sun gear 1002 is detachably connected to the cutter 6.

[0046] When motor 5 outputs power, the central gear 901 rotates, driving planetary gear 1004 in the second planetary gear set 9 to rotate. This, in turn, drives the sun gear 1002 and ring gear 1003 in the second planetary gear set 9 to rotate, which in turn causes the impeller 405 and cutter 6 to rotate. The rotation of impeller 405 generates negative pressure, causing water to flow from water tank 4 to outlet 401 and spray out. The cutter 6 rotates to perform cleaning and unblocking work. The operator can control the start and stop of motor 5 through automated operation, thereby controlling the cleaning, unblocking, and water spraying operations of the cleaning and unblocking body 1.

[0047] As a third embodiment of the present invention, based on embodiment 2, with reference to Figure 7-9The lifting controller 2 is located on the upper end of the cleaning and dredging body 1. The end of the wire rope 203 in the lifting controller 2 is fixed to a horizontal surface. The lifting controller 2 operates similarly to a winch; its rotation retracts and releases the wire rope 203. Since this is an existing structure, it will not be described in detail here. A first planetary gear set 10 is located between the motor 5 and the second planetary gear set 9. The first planetary gear set 10 consists of a planet carrier 1001, a sun gear 1002, three planetary gears 1004, and a ring gear 1003. The motor 5 is connected to the planet carrier 1001. A lifting main gear 207 meshes with the outer wall of the ring gear 1003 in the first planetary gear set 10. A lifting transmission rod 206 is mounted on the lifting main gear 207. A second lifting gear 205 is located at the end of the lifting transmission rod 206, and the second lifting gear 205 meshes with the first lifting gear 204 used to drive the lifting controller 2. The sun gear 1002 in the first planetary gear set 10 is connected to the center gear 901 via a connecting rod 15.

[0048] A switching assembly 11 is also provided on the first planetary gear set 10. The switching assembly 11 includes a friction disc 1101 for limiting the rotation of the ring gear 1003 in the first planetary gear set 10. A hollow sleeve 1102 is provided on the side of the friction disc 1101 near the second planetary gear set 9. The hollow sleeve 1102 is sleeved on the connecting rod 15. Friction strips 1103 are evenly distributed in annular pattern on the inner wall of the hollow sleeve 1102. A plurality of third return springs 1104 are provided between the friction strips 1103 and the inner wall of the hollow sleeve 1102. The cross-sectional radius of the connecting rod 15 near the first planetary gear set 10 is smaller than the cross-sectional radius away from the first planetary gear set 10.

[0049] When the cleaning and unblocking body 1 is working, the automated control panel 12 moves the switching component 11, causing the friction disc 1101 to abut against the gear ring 1003 in the first planetary gear set 10 and remain stationary. At this time, the motor 5 receives input from the planet carrier 1001 in the first planetary gear set 10 and outputs from the sun gear 1002 in the first planetary gear set 10, thereby outputting from the second planetary gear set 9 to perform corresponding operations. When the cleaning and unblocking body 1 moves, the automated control panel 12 moves the switching component 11, causing the gear ring 1003 in the first planetary gear set 10 to abut against the friction disc 1101. 01 no longer abuts, the hollow sleeve 1102 moves to a position where the connecting rod 15 is away from the first planetary gear set 10, the third return spring 1104 is compressed, and the friction strip 1103 abuts against the connecting rod 15, thereby stopping the sun gear 1002 in the first planetary gear set 10. At this time, the motor 5 inputs from the planet carrier 1001 in the first planetary gear set 10 and outputs from the gear ring 1003 in the first planetary gear set 10, thereby driving the lifting controller 2 to work, realizing the movement of the cleaning and unblocking body 1, thus avoiding the constant opening and closing of the motor 5 and extending its service life. The lifting and lowering of the cleaning and unblocking body 1 can be controlled by forward and reverse rotation. There are various ways to control the movement of the switching component 11 in the prior art. For example, the telescopic hydraulic rod is connected to the switching component, and the movement of the switching component 11 is realized by the extension and retraction of the telescopic hydraulic rod. The telescopic hydraulic rod can be electrically connected to the automated operating table 12, and the extension and retraction of the telescopic hydraulic rod can be controlled by controlling the automated operating table 12. Since the ways to control the movement of the switching component 11 are all prior art, they will not be described in detail here.

[0050] As a fourth embodiment of the present invention, based on embodiment 3, with reference to Figure 10 and Figure 11 The hollow sleeve 1102 has serrations 1105 on its outer wall. The serrations 1105 mesh with a supporting main gear 807. The supporting main gear 807 corresponds in number and position to the supporting components 8. In this embodiment, the supporting component 8 is a telescopic rod 803. The fixed part of the telescopic rod 803 slides through the side wall of the cleaning and unblocking body 1. A threaded sleeve 806 is rotatably provided on the inner wall of the cleaning and unblocking body 1. The threaded sleeve 806 is rotatably threaded onto the fixed part of the telescopic rod 803. The supporting main gear 807 is connected to the threaded sleeve 806. A support plate 802 is provided at the end of the telescopic rod 803. A second return spring 804 is sleeved at the telescopic part of the telescopic rod 803.

[0051] When the switching component 11 moves closer to the gear ring 1003 in the first planetary gear set 10, it drives the supporting main gear 807 to rotate forward, thereby driving the threaded sleeve 806 to rotate forward, and causing the telescopic rod 803 to slide out. When the support plate 802 presses against the side wall of the drainage riser 14, the fixed part of the telescopic rod 803 continues to slide out, and the second return spring 804 is compressed. The restoring force of the second return spring 804 is the supporting force provided by the supporting component 8. When the switching component 11 moves away from the gear ring 1003 in the first planetary gear set 10, the supporting main gear 807 reverses, thereby driving the threaded sleeve 806 to reverse, and causing the supporting component 8 to retract.

[0052] As a fifth embodiment of the present invention, based on embodiment 4, with reference to... Figure 12 A hollow hydraulic rod 805 is fitted onto the telescopic part of the telescopic rod 803. The hollow hydraulic rod 805 is connected to the second return spring 804. When the support assembly 8 is tightened, the hollow hydraulic rod 805 extends or retracts, which can adjust the length of the second return spring 804, thereby adjusting the magnitude of the support force.

[0053] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above description or related technical or knowledge.
