Description

Technical Field

[0001] This application relates to the technical field of pipe unblocking, and in particular to a pipe unblocking device and its usage method. Background Technology

[0002] In the use of household drainage pipes, building drainage pipes, municipal pipes, and industrial pipes, dirt and other debris gradually accumulate inside the pipes over time, causing the cross-sectional area of ​​the flow path inside the pipe to decrease, or even causing pipe blockage, thereby affecting the drainage performance of the pipes.

[0003] When a pipe becomes blocked, construction workers typically use a flexible rod with barbs at the end to remove the blockage. Some may introduce a booster pump into the pipe and seal the pipe inlet to increase the air pressure inside the pipe and thus clear the blockage.

[0004] However, there are many problems with the application of this technology. When using a barbed, flexible rod for excavation, it can be quite laborious if the blockage is hard, and it can also increase the difficulty of excavation if the blockage is far from the point of dredging. When using a booster pump to unclog pipes, the high-pressure gas can damage the pipes and even cause leaks. Summary of the Invention

[0005] In order to unclog pipes, improve the convenience of pipe dredging operations, and reduce damage to pipes during dredging, this application provides a pipe dredging device and its usage method.

[0006] Firstly, this application provides a pipe dredging device, which adopts the following technical solution: A pipe unblocking device includes a breaking component, a sealing component, and a bending component; The bending assembly includes a bellows; the sealing assembly includes a support pipe, which is connected to the bellows, and the support pipe and the bellows are used to introduce gas. The sealing assembly also includes an umbrella-shaped structure for sealing the pipeline, the umbrella-shaped structure being disposed on the support pipe; The breaking assembly includes a first driving source, which is disposed on the support tube; the breaking assembly also includes a drill bit, which is connected to the rotation shaft of the first driving source. The support tube is provided with a pushing assembly, which includes a second driving source for opening or closing the umbrella body.

[0007] By adopting the above technical solution, when the breaking component is moved to contact the blockage through the corrugated pipe, the first drive source is turned on to drive the drill bit to rotate. The drill bit drills and excavates the blockage, thereby loosening it. After the drill bit has excavated, the pushing component opens the umbrella body and seals the pipe. A cavity is formed between the umbrella body and the blockage. At this time, gas is introduced into the corrugated pipe to increase the air pressure in the cavity, thereby pushing the blockage and clearing it. Because this application introduces gas only after drilling, it can reduce the damage to the pipeline to a certain extent compared with the prior art.

[0008] Optionally, the sealing assembly further includes a first slider, which is slidably sleeved on the support tube; The second driving source drives the first slider to slide; The umbrella body is provided with an attachment block for attaching to the inner wall of the pipe; The sealing assembly further includes a first push rod, one end of which is hinged to the first slider, and the other end of which is hinged to the attachment block.

[0009] By adopting the above technical solution, when the extrusion and pushing assembly drives the first slider to slide, the first slider drives the first push rod to push the attachment block to move, thereby opening the umbrella body. The attachment block fits with the inner wall of the pipe, thereby forming a cavity between the umbrella body and the blockage. When gas is introduced into the corrugated pipe, high pressure is formed in the cavity, which is conducive to clearing the blockage.

[0010] Optionally, multiple adhesive blocks are evenly arranged along the outer circumferential wall of the umbrella body, and multiple first push rods are also provided, with the first push rods corresponding to the adhesive blocks.

[0011] By adopting the above technical solution, when multiple attachment blocks are set on the circumferential outer wall of the umbrella body, the first slider drives the first push rod to open the umbrella body, which can make the area of ​​the umbrella body close to the cross-sectional area of ​​the pipe, thereby improving the sealing effect of the umbrella body to a certain extent.

[0012] Optionally, the support tube is provided with an opening and closing assembly, the opening and closing assembly including a second slider, the second slider being slidably sleeved on the support tube; the second driving source is also used to drive the second slider to slide. The opening and closing assembly also includes a protective shell for opening or covering the drill bit, the protective shell being hinged to the umbrella body; The opening and closing assembly also includes a second push rod, one end of which is hinged to the second slider, and the other end of which is hinged to the protective shell.

[0013] By adopting the above technical solution, when the extrusion and pushing assembly drives the second slider to slide, the second slider drives the second push rod to move to open the protective shell, which makes it easier for the drill bit to extend and drill out the blockage.

[0014] Optionally, the protective shell has a storage chamber for storing drain cleaner.

[0015] By adopting the above technical solution, when the extrusion assembly drives the second slider to slide, the protective shell is opened. At this time, the pipe cleaner located in the storage chamber falls out and reacts with the blockage, which is conducive to drilling and digging, and facilitates the unblocking operation.

[0016] Optionally, the second driving source is disposed on the second slider; The extrusion assembly further includes a support base, which is connected to the first slider; The extrusion assembly also includes a lead screw, one end of which is connected to the rotating shaft of the second drive source, and the other end of which passes through the support base and is threadedly connected to the support base.

[0017] By adopting the above technical solution, when the second drive source drives the lead screw to rotate, the lead screw can drive the support seat to move relative to each other. That is, the second drive source can cause the first slider and the second slider to move relative to each other, thereby opening the umbrella and the protective shell simultaneously, or closing the umbrella and the protective shell simultaneously.

[0018] Optionally, the second driving source is disposed on the second slider; The extrusion assembly further includes a fixed base, which is connected to the first slider; The second drive source also includes an electric push rod, which is connected to the second slider, and the output end of the electric push rod is connected to the fixed base.

[0019] By adopting the above technical solution, one end of the electric push rod is connected to the second slider and the other end is connected to the fixed base. When the electric push rod pushes the fixed base to move, it can drive the first slider and the second slider to move relative to each other, so that the umbrella body and the protective shell can be opened or closed simultaneously.

[0020] Optionally, the pipe clearing device further includes a pressurization component, which includes a frame, a winding drum, and an air pump; The winding drum is rotatably connected to the frame, and the corrugated pipe is wound around the winding drum; the air pump is mounted on the frame and is connected to the corrugated pipe.

[0021] By adopting the above technical solution, after the drill bit has been drilling for several minutes, the air pump is turned on to pump air into the corrugated pipe, which helps to clear the blockage inside the pipe; the winding drum can easily wind up or unwind the corrugated pipe, improving the ease of operation.

[0022] Optionally, the bending assembly includes a flexible end, which is disposed on the side of the corrugated pipe near the umbrella body, and the support pipe is connected to the flexible end; a deformation bladder that opens or closes with the umbrella body is enclosed between the flexible end and the umbrella body.

[0023] By adopting the above technical solution, the tough end can provide support for the support pipe, and the tough end and the corrugated pipe work together to facilitate the movement of the breaking component in the pipe; the deformation bladder covering the umbrella body and the tough end can reduce the situation where debris in the pipe enters the umbrella body due to vibration.

[0024] Secondly, this application also provides a method for using a pipe dredging device, which includes the following steps: S1: Rotate the bobbin and unwind the corrugated tube, insert the corrugated tube into the pipe, adjust the position of the breaking component through the corrugated tube and make it contact the blockage; S2: Start the second driver source first, and then start the first driver source; S3: Turn on the air pump after waiting a few minutes; S4: Turn on the air pump for a few minutes and then turn it off. First, turn off the second drive source, then turn off the first drive source, and finally rewind the bellows.

[0025] By adopting the above technical solution, the corrugated pipe is unwound to make the breaking component contact the blockage, the second drive source is turned on to open the umbrella body, and then the first drive source is turned on to make the drill bit drill and dig out the blockage. After drilling for several minutes, the air pump is turned on, and the gas pressure in the pipe increases, thereby clearing the blockage. After the blockage is cleared, the second drive source is turned off and then the first drive source is turned off. Then the corrugated pipe is wound up to complete the clearing operation.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. The first drive source drives the drill bit to drill and excavate the blockage, thereby loosening the blockage. After the drill bit has drilled, the extrusion assembly causes the umbrella body to seal the pipe, forming a cavity between the umbrella body and the blockage. Gas is introduced into the bellows, increasing the air pressure in the cavity, which helps to clear the blockage and reduce damage to the pipe. 2. The extrusion assembly can simultaneously push the first slider and the second slider to move relative to each other, thereby enabling the umbrella body and the protective shell to open synchronously, or enabling the umbrella body and the protective shell to close synchronously; 3. When the protective shell is opened, the drain cleaner in the storage compartment reacts with the blockage, which facilitates the unblocking operation. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0030] Example 1: Embodiment 1 of this application discloses a pipe dredging device.

[0031] refer to Figure 1 and Figure 2A pipe clearing device includes a breaking component 1, a bending component 3, and a pressurizing component 6. The bending component 3 is disposed on the pressurizing component 6, and the breaking component 1 is disposed on the bending component 3. The bending component 3 facilitates the movement of the breaking component 1 within the pipe 7. The breaking component 1 is used to break up the blockage 8, thereby facilitating the clearing of the blockage 8.

[0032] refer to Figure 3 The pressurization assembly 6 includes a frame 61, which is placed at the operating position. A winding drum 62 is rotatably connected to the frame 61. The bending assembly 3 includes a bellows 32, which is wound around the winding drum 62. When the winding drum 62 is rotated, the bellows 32 can be wound and unwound. An air pump 63 is fixedly connected to the frame 61. One end of the bellows 32 is connected to the air pump 63, thereby enabling the bellows 32 to transmit pressurized gas.

[0033] refer to Figure 4 The bending assembly 3 also includes a flexible end 31, and the end of the bellows 32 away from the air pump 63 is fixedly connected to the flexible end 31. Both the bellows 32 and the flexible end 31 have a certain degree of flexibility, and the flexibility of the flexible end 31 is higher than that of the bellows 32.

[0034] When the corrugated pipe 32 is inserted into the pipe 7 and moves within the pipe 7, the corrugated pipe 32, which has a certain degree of toughness, can transmit force along its own length, so as to facilitate the movement of the breaking component 1 within the pipe 7. When the breaking component 1 encounters a bend in the pipe 7, the tough end 31 facilitates the movement of the breaking component 1 along the direction of the bend in the pipe 7.

[0035] refer to Figure 2 and Figure 4 A sealing component 2 is provided at the end of the flexible end 31 away from the corrugated pipe 32. The sealing component 2 includes a support pipe 21, which is inserted into the flexible end 31 and is fixedly connected to the flexible end 31. The support pipe 21 is connected to the corrugated pipe 32.

[0036] refer to Figure 4 and Figure 5 The sealing assembly 2 also includes an umbrella body 22, with a support tube 21 disposed inside the umbrella body 22. The umbrella body 22 is generally conical, and its cross-sectional area gradually decreases from the direction near the flexible end 31 to the direction away from the flexible end 31. An attachment block 26 is fixedly connected to the side of the umbrella body 22 near the flexible end 31, and the attachment block 26 is located on the outside of the umbrella body 22.

[0037] refer to Figure 5 The first slider 23 is slidably sleeved on the support tube 21. The sealing component 2 also includes a first push rod 24. One end of the first push rod 24 is hinged to the first slider 23, and the other end of the first push rod 24 is hinged to the attachment block 26.

[0038] When the first slider 23 slides along the support tube 21 toward the direction closer to the flexible end 31, the first slider 23 drives the first push rod 24 to move, thereby opening the umbrella body 22; when the first slider 23 slides along the support tube 21 away from the flexible end 31, the first slider 23 drives the first push rod 24 to close the umbrella body 22.

[0039] To ensure more even force distribution on the umbrella body 22 when it is opened and closed, multiple attachment blocks 26 can be uniformly fixed to the outer wall of the umbrella body 22. Multiple first push rods 24 are correspondingly arranged between the attachment blocks 26 and the first slider 23. In this embodiment, eight attachment blocks 26 and first push rods 24 are provided. The attachment blocks 26 are made of a material with a certain degree of elasticity (such as rubber), which allows the attachment blocks 26 to better adhere to the inner wall of the pipe 7.

[0040] refer to Figure 4 The sealing assembly 2 also includes a deformation bladder 25, which is located between the flexible end 31 and the umbrella body 22. One end of the deformation bladder 25 is fixedly connected to the flexible end 31, and the other end is fixedly connected to the end of the umbrella body 22 near the flexible end 31. When the umbrella body 22 is opened or closed, the deformation bladder 25 can move with the umbrella body 22, that is, the deformation bladder 25 can seal the connection between the flexible end 31 and the umbrella body 22.

[0041] When the umbrella body 22 is located inside the pipe 7, the deformation bladder 25 can improve the situation where debris inside the pipe 7 enters the umbrella body 22 and affects the operation of the internal structure.

[0042] refer to Figure 5 and Figure 6 The umbrella body 22 is equipped with a pushing assembly 5, which can push the first slider 23 to slide. The support tube 21 has a vent hole 211, which can be discharged from the vent hole 211 when gas is introduced into the support tube 21.

[0043] When the first slider 23 drives the first push rod 24 to open the umbrella body 22, the attachment block 26 adheres to the inner wall of the pipe 7, and the deformation bladder 25 opens with the umbrella body 22, forming a relatively closed cavity between the blockage 8 and the deformation bladder 25. The air pump 63 is started to pump air into the bellows 32, and the gas is discharged from the vent 211 into the cavity, increasing the air pressure inside the cavity, thereby helping to clear the blockage 8.

[0044] refer to Figure 5 The support tube 21 is provided with an opening and closing component 4 at the end away from the flexible end 31. The opening and closing component 4 includes a protective shell 43. There are two protective shells 43. In this embodiment, the two protective shells 43 can be spliced ​​together to form a cone.

[0045] refer to Figure 5 and Figure 6The opening and closing assembly 4 also includes a second slider 41, which is slidably sleeved on the end of the support tube 21 away from the flexible end 31. The support tube 21 passes through the second slider 41, thereby allowing the second slider 41 to slide along the length of the support tube 21. A pushing assembly 5 is disposed on the second slider 41, which enables the first slider 23 and the second slider 41 to slide relative to each other.

[0046] refer to Figure 6 The opening and closing assembly 4 also includes a second push rod 42, one end of which is hinged to the second slider 41, and the other end of which is hinged to the inner wall of the protective shell 43. There are two second push rods 42, and each of the two second push rods 42 corresponds to one of the two protective shells 43.

[0047] refer to Figure 6 The opening and closing assembly 4 also includes a hinge seat 45, which is divided into two hinged parts. One part of the hinge seat 45 is fixedly connected to the umbrella body 22, and the other part of the hinge seat 45 is fixedly connected to the protective shell 43, thereby making the protective shell 43 hinged to the umbrella body 22. There are two hinge seats 45, and the two hinge seats 45 correspond one-to-one with the two protective shells 43.

[0048] refer to Figure 6 The hinge seat 45 has a torsion spring 46 on its rotating shaft, and the torsion spring 46 makes the force required to open the protective shell 43 greater than the force required to open the umbrella body 22. That is, when the pushing assembly 5 pushes the first slider 23 and the second slider 41, the umbrella body 22 can open before the protective shell 43. After the attaching block 26 is attached to the inner wall of the pipe 7, the pushing assembly 5 will drive the second slider 41 to open the protective shell 43.

[0049] Within the applicable scope of this device, if the diameter of the pipe 7 is small, the protective shell 43 will open at a larger angle after the attachment block 26 abuts against the inner wall of the pipe 7; if the diameter of the pipe 7 is large, the protective shell 43 will open at a smaller angle after the attachment block 26 abuts against the inner wall of the pipe 7; thus, the umbrella body 22 can adapt to pipes 7 of different diameters, improving the applicability of this device.

[0050] refer to Figure 6 When the two protective shells 43 are joined together, they form a storage chamber 44, which can store drain cleaner. The main components of the drain cleaner are caustic soda and aluminum powder. When the two protective shells 43 are separated, the drain cleaner falls out and comes into contact with the blockage 8, reacting to generate heat and gas, which helps to clear the blockage 8.

[0051] refer to Figure 6The breaking component 1 also includes a first driving source 11. In this embodiment, the first driving source 11 is a motor, which is fixedly connected to the side of the second slider 41 away from the tough end 31. The output shaft of the motor is fixedly connected to a drill bit 12. When the two protective shells 43 are closed, the drill bit 12 is located inside the two protective shells 43.

[0052] refer to Figure 5 and Figure 6 The extrusion assembly 5 includes a second drive source 51. In this embodiment, the second drive source 51 is a servo motor, which is fixedly connected to the second slider 41. The output shaft of the servo motor is fixedly connected to a lead screw 52, ​​and the first slider 23 is fixedly connected to a support base 53. The lead screw 52 passes through the support base 53 and is threadedly connected to the support base 53.

[0053] When the second drive source 51 drives the lead screw 52 to rotate, the lead screw 52 can push the support seat 53 to move relative to each other, thereby causing the first slider 23 and the second slider 41 to move relative to each other. The second slider 41 drives the second push rod 42 to open the protective shell 43, and the drain cleaner 7 falls from the storage chamber 44 and reacts with the blockage 8. Due to the movement of the second slider 41, the drill bit 12 extends from between the two protective shells 43 and comes into contact with the blockage 8. The first drive source 11 drives the drill bit 12 to rotate, thereby making the blockage 8 looser and facilitating the unblocking of the blockage 8.

[0054] It is worth noting that the driving distance of the second drive source 51 should be selected reasonably to avoid mechanical problems such as jamming between the second push rod 42 and the first push rod 24, and also to prevent the second slider 41 from detaching from the support tube 21. Waterproof coating can be applied to the surfaces of the first drive source 11 and the second drive source 51 to reduce the impact of water splashed during drilling by the drill bit 12. The wires of the control switches for the first drive source 11 and the second drive source 51 can be run through the corrugated pipe 32, and the control switches can be mounted on the frame 61, thus facilitating the control of the first drive source 11 and the second drive source 51.

[0055] refer to Figure 7 and Figure 8 If the blockage 8 is thick and the drill bit 12 inside the protective shell 43 extends a short distance, in other embodiments of this application, the two protective shells 43 can be spliced ​​together to form a frustum shape, and the drill bit 12 passes through the protective shell 43. That is, when the two protective shells 43 are closed, the drill bit 12 has already extended a certain distance, which is beneficial for the drill bit 12 to drill through the thicker blockage 8.

[0056] In this embodiment, although gas pressure is also needed to clear the blockage 8, it differs from related technologies that directly rely on high-pressure gas to push the blockage 8. In this application, the air pump 63 is started several minutes after the drill bit 12 has been working. At this time, the blockage 8 is already in a loosened state. Therefore, compared with this application, the gas pressure is only an auxiliary means to clear the blockage 8. Furthermore, after the eight attachment blocks 26 of this application are attached to the inner wall of the pipe 7, they form an approximate circle with the same diameter as the pipe 7. That is, there is a gap between the umbrella body 22 and the inner wall of the pipe 7. When the gas pressure in the cavity is too high, a small amount of gas can flow out from the gap, thereby reducing the damage of high-pressure gas to the pipe 7. At the same time, when the gas pressure in the cavity is too high, the deformation bladder 25 deforms to a certain extent in the direction closer to the tough end 31, which can also reduce the damage of high-pressure gas to the pipe 7 to a certain extent.

[0057] The implementation principle of the pipe unblocking device in Embodiment 1 of this application is as follows: By adjusting the corrugated pipe 32 and the flexible end 31, the protective shell 43 is brought into contact with the blockage 8. The second drive source 51 is turned on, causing the umbrella body 22 to open and fit against the inner wall of the pipe 7. Then, the protective shell 43 is opened, allowing the pipe unblocking agent located in the storage chamber 44 to act on the blockage 8. The first drive source 11 is turned on, and the drill bit 12 can drill and excavate the blockage 8. After drilling for several minutes, the air pump 63 is turned on, increasing the gas pressure in the pipe 7, thereby unblocking the blockage 8.

[0058] This application also provides a method for using a pipe dredging device, which includes the following steps: S1: Rotate the winding drum 62 and unwind the corrugated tube 32, insert the corrugated tube 32 into the pipe 7, adjust the position of the breaking component 1 through the corrugated tube 32 and make it contact the blockage 8; S2: First start the second driver source 51, and then start the first driver source 11; S3: Wait a few minutes and then turn on air pump 63; S4: Turn on the air pump 63 for several minutes and then turn it off. First, turn off the second drive source 51, then turn off the first drive source 11, and finally rewind the bellows 32.

[0059] Example 2: Embodiment 2 of this application discloses a pipe dredging device.

[0060] refer to Figure 9 and Figure 10 The difference between Embodiment 2 and Embodiment 1 is that the extrusion assembly 5 includes a second drive source 51. In this embodiment, the second drive source 51 is an electric push rod 511, which is fixedly connected to the second slider 41. The first slider 23 is fixedly connected to a fixed seat 54, and the output shaft of the electric push rod 511 is fixedly connected to the fixed seat 54.

[0061] The implementation principle of the pipe dredging device in Embodiment 2 of this application is as follows: when the electric push rod 511 pushes the fixed base 54 to move, it can drive the first slider 23 and the second slider 41 to move relative to each other, thereby opening the umbrella body 22 and the protective shell 43 simultaneously, or closing the umbrella body 22 or the protective shell 43 simultaneously.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
