Description

Technical Field

[0001] The present invention relates to the technical field of inspection wells, and particularly relates to a connecting device and a connecting method between an inspection well and a drainage pipe. Background Art

[0002] An inspection well is an important part of the urban drainage system, mainly used for inspecting, maintaining and cleaning drainage pipes to ensure the smoothness of the drainage system. Inspection wells are usually set at intersections, elbows, positions where the pipe slope changes, and places where the inspection and cleaning of drainage pipes are required.

[0003] The connection between the existing inspection well and the drainage pipe is filled with cement to fill the gap. During long-term use, the cement seal may gradually reduce the sealing performance due to problems such as expansion, contraction or aging of the cement, resulting in water leakage, which affects the normal operation of the drainage system. Moreover, the cement seal usually requires a long curing time, and high technical requirements are needed during the construction process to ensure the stability and sealing effect of the sealed joint. Maintenance and repair are difficult. Once the cement seal is damaged or aged, it is more troublesome to repair, and the original cement structure needs to be destroyed and re-constructed, increasing the maintenance cost and construction period. The seismic resistance is poor. The connection of the cement seal may break or shift when encountering an earthquake or ground settlement, resulting in unstable connection and difficulty in adapting to the thermal expansion and contraction of the pipe. The cement seal has strong rigidity and is difficult to adapt to the thermal expansion and contraction phenomenon caused by temperature changes in the pipe. In addition, the connection between the existing inspection well and the drainage pipe is constructed manually, which reduces work efficiency, and it is difficult to locate the center of the drainage pipe, resulting in inaccurate sealing. Summary of the Invention

[0004] Based on the technical problem that the connection between the existing inspection well and the drainage pipe is sealed by manually applying cement, which may gradually reduce the sealing performance due to problems such as expansion, contraction or aging of the cement, resulting in water leakage, affecting the normal operation of the drainage system, and manual operation is required, reducing work efficiency, the present invention proposes a connecting device and a connecting method between an inspection well and a drainage pipe.

[0005] A connecting device between an inspection well and a drainage pipe proposed by the present invention includes an inspection well and a drainage pipe. A connecting device, a supporting device and a conveying device are arranged on the outer surface of the inspection well.

[0006] The connecting device is located at the connection port of the inspection well and connects the inspection well and the drainage pipe. The connecting device includes a connecting rubber ring with a feeding end, and the connecting rubber ring seals the gap between the inspection well and the drainage pipe.

[0007] The support device is located on the outer surface of the inspection well and supports the connecting rubber ring. The support device includes a fixing mechanism and a support mechanism. The fixing mechanism fixes the position of the support mechanism, and the support mechanism supports the connecting rubber ring after contacting the inner wall of the connecting rubber ring.

[0008] The conveying device is located outside the inspection well and conveys foaming agent into the connecting rubber ring. The conveying device includes a conveying mechanism and a clamping mechanism. The conveying mechanism conveys the foaming agent into the connecting rubber ring, and the clamping mechanism clamps the feeding end of the connecting rubber ring.

[0009] Preferably, the outer surface of the connecting rubber ring contacts the inner wall of the connecting port of the inspection well, and a support annular spring is fixedly installed on the inner wall of the connecting rubber ring.

[0010] Through the above technical solution, the gap between the drainage pipe and the connecting port of the inspection well is filled by the connecting rubber ring, and the inside of the connecting rubber ring can be filled with foaming agent or concrete, so that the connection between the drainage pipe and the inspection well is tight, not affected by the thermal expansion and contraction of the drainage pipe and time, reducing the possibility of water leakage. The support annular spring enables the middle section of the connecting rubber ring to be propped up, facilitating the complete filling of the foaming agent.

[0011] Preferably, the fixing mechanism further includes a fixing disk. The fixing disk is arranged inside the inspection well. The upper surface of the fixing disk is rotatably connected with a rotating disk with an arc-shaped groove and a tooth groove through a bearing. A limiting sliding groove is fixedly installed on the upper surface of the fixing disk. A fixing ring is slidably inserted into the inner wall of the limiting sliding groove. One end of the fixing ring is slidably inserted into the inner wall of the arc-shaped groove of the rotating disk through a column. A self-locking gear is rotatably connected to the upper surface of the fixing disk, and the self-locking gear meshes with the tooth groove of the rotating disk.

[0012] Through the above technical solution, the self-locking gear meshing with the tooth groove of the rotating disk can perform self-locking. By rotating the self-locking gear, the rotating disk can be driven to rotate. The rotation of the rotating disk can adjust the position of the fixing ring, so as to adapt to inspection wells of various different diameters and facilitate the fixing of the fixing disk.

[0013] Preferably, a support frame is fixedly installed on the upper surface of the fixed disk. A rotating gear is rotatably connected to the outer surface of the support frame through a bearing. A fixed motor is fixedly installed on the outer surface of the support frame. One end of the output shaft of the fixed motor is engaged with the rotating gear through a gear. An elevating thread sleeve is threadedly connected to the inner wall of the rotating gear. The outer surface of the elevating thread sleeve is slidably inserted into the inner wall of the fixed disk. One end of the elevating thread sleeve is fixedly installed with a connecting frame. A pushing rack is slidably inserted into the inner wall of the connecting frame. A driving gear with a bevel gear is rotatably connected to the outer surface of the connecting frame through a bearing. The driving gear is engaged with the pushing rack. A rotating rod with a bevel gear is rotatably connected to the outer surface of the connecting frame through a bearing. The bevel gear of the rotating rod is engaged with the bevel gear of the driving gear.

[0014] Through the above technical solution, the elevating thread sleeve is lifted and lowered by the rotation of the rotating gear, so that the position of the support mechanism can be adjusted, enabling the support mechanism to be relative to the connection port of the inspection well, thereby completing the support of the drainage pipe. By driving the rotation of the rotating rod and using the transmission of the bevel gear, the driving gear can be driven to rotate, thereby driving the pushing rack to adjust the position of the support mechanism, facilitating the support mechanism to penetrate into the drainage pipe.

[0015] Preferably, the support mechanism includes a support motor. The support motor is fixedly installed on the outer side of the pushing rack. A support housing is fixedly installed on the outer surface of the pushing rack. A driving gear disk is rotatably connected to the inner wall of the support housing. One end of the output shaft of the support motor is fixedly installed with the driving gear disk through a connecting shaft. A support block is slidably inserted into the inner wall of the support housing. One end of the support block is slidably connected to the outer side of the driving gear disk. A return spring is fixedly installed on the outer surface of the support block. One end of the return spring is connected to the outer surface of the support housing.

[0016] Through the above technical solution, in order to support the drainage pipe, the drainage pipe is driven to automatically penetrate through the connection port of the inspection well, and at the same time, the drainage pipe is located at the center of the connection port of the inspection well, so that the connecting rubber ring is not pressed by the drainage pipe on the inner wall of the connection port, enabling the foaming agent to be evenly filled. By the rotation of the driving gear disk, the support block can be pushed to move outwards, thereby supporting the drainage pipe.

[0017] Preferably, the conveying mechanism includes a base disposed on one side of the inspection well. A storage tank is fixedly installed on the upper surface of the base, and a delivery pump is fixedly installed on the upper surface of the base. The input end of the delivery pump is fixedly installed with the outlet of the storage tank through a connecting pipe. An arc-shaped conveying pipe is fixedly installed on the upper surface of the base through a bracket. The output end of the delivery pump is fixedly communicated with one end of the arc-shaped conveying pipe. One end of the arc-shaped conveying pipe is fixedly installed with a plug-in conveying pipe, and one end of the plug-in conveying pipe is slidably inserted into the inner wall of the feeding end of the connecting rubber ring.

[0018] Through the above technical solution, the foaming agent is stored in the storage tank, and the foaming agent can be conveyed by the suction of the delivery pump, which is convenient for automatically filling the conveying rubber ring.

[0019] Preferably, the clamping mechanism includes a clamping frame. A moving component is fixedly installed on the outer surface of the clamping frame. A moving frame is threadedly connected to the outer surface of the lead screw of the moving component. One end of the moving frame is slidably inserted into the outer surface of the limiting rod of the moving component. A pushing hydraulic cylinder is fixedly installed on the outer surface of the moving frame. One end of the piston rod of the pushing hydraulic cylinder is fixedly installed with a pushing plate. A clamping rod is slidably inserted into the inner wall of the moving frame through a slider. A deflecting connecting rod is hinged to the outer surface of the clamping rod through a pin shaft, and one end of the deflecting connecting rod is hinged to one end of the pushing plate through a pin shaft.

[0020] Through the above technical solution, the moving component includes a frame body, a lead screw rotatably connected to the frame body, a limiting rod fixedly installed on the frame body, and a motor. By starting the motor to rotate the lead screw, the moving frame can be driven to move, and the position of the clamping mechanism can be adjusted.

[0021] Preferably, one end of the clamping rod is rotatably connected with a connecting block, and a fixed clamping block is fixedly installed on one side of the connecting block. The relative movement of the fixed clamping blocks clamps the feeding end of the connecting rubber ring.

[0022] Through the above technical solution, in order to prevent the feeding end of the connecting rubber ring from leaking when conveying the foaming agent, and to prevent the feeding end of the connecting rubber ring from being separated from the plug-in conveying pipe under pressure when conveying the foaming agent, the relative movement of the fixed clamping blocks is used to clamp the feeding end sleeved on the plug-in conveying pipe, so that the feeding end of the connecting rubber ring is fixed on the plug-in conveying pipe.

[0023] Preferably, a heating block is fixedly installed on the outer surface of the connecting block, a switching gear is fixedly installed on the outer surface of the connecting block, a switching frame is fixedly installed on the upper surface of the base, a switching rack is fixedly installed on the outer surface of the switching frame, the switching rack meshes with the switching gear, a scraping plate is slidably inserted on the outer surface of the connecting block, a connecting spring is fixedly installed on the outer surface of the scraping plate, one end of the connecting spring is fixedly installed on the outer surface of the connecting block, a ball is rotatably connected to one end of the scraping plate, a pushing chute is fixedly installed on the outer surface of the switching frame, and the inner wall of the pushing chute is slidably connected to the outer surface of the ball.

[0024] Through the above technical solution, in order to seal the feeding end of the connecting rubber ring and prevent the internal foaming agent from being affected by the outside world, after the switching rack meshes with the switching gear, it can drive the connecting block to turn, complete the switching between the fixed clamping block and the heating block, so that the heating block can face the connecting rubber ring. When the ball on the scraping plate is pressed by the track of the pushing chute, it can descend, pushing the foaming agent in the feeding end of the connecting rubber ring, facilitating the thermal pressing at the feeding end to complete the sealing.

[0025] A connection method for a connection device between an inspection well and a drainage pipe proposed by the present invention includes the following steps:

[0026] S1: First, sleeved the connecting rubber ring on the connection port of the inspection well, then rotate the self-locking gear according to the diameter of the inspection well opening. The self-locking gear drives the rotating disc to rotate, and the rotating disc drives the fixed ring in the limit chute to move outwards through the arc-shaped groove. The inner surfaces of multiple fixed rings can fit the outer surface of the inspection well, so that the fixed disc can be fixed on the inspection well.

[0027] S2: According to the position of the connection port of the inspection well, control the fixed motor on the support frame to start. After the fixed motor starts, it drives the rotating gear to rotate. The rotation of the rotating gear drives the lifting thread sleeve to descend, so as to drive the connecting frame to descend. After the center line of the support housing and the center line of the inspection well connection port are on the same horizontal line, by rotating the rotating rod on the connecting frame, the rotating rod drives the pushing gear to rotate through the bevel gear. After the pushing gear pushes the pushing rack slidably inserted on the connecting frame to move horizontally, the pushing rack makes the support housing penetrate out of the outer surface of the inspection well.

[0028] S3: After sleeved the drainage pipe on the outer surface of the support housing, start the support motor on the pushing rack, drive the pushing gear disc to rotate. The rotation of the pushing gear disc drives the support block to move outwards, and the return spring is stretched. The support block is inserted into the inner wall groove of the drainage pipe to complete the support of the drainage pipe. The pushing rack moves, driving the drainage pipe to be inserted into the connecting rubber ring.

[0029] S4: Sheath the feed end of the connecting rubber ring on the outer surface of the plug-in conveying pipe. Start the hydraulic cylinder to drive the push plate to move. The push plate drives the clamping rod to move relatively on the moving frame through the deflecting connecting rod. The fixed clamping block on the clamping rod clamps the feed end of the connecting rubber ring on the plug-in conveying pipe.

[0030] S5: After the delivery pump on the base starts, it sucks the foaming agent in the storage tank and conveys it into the arc-shaped conveying pipe, and then conveys it to the fixed connecting rubber ring through the arc-shaped conveying pipe, so that the space inside the connecting rubber ring is filled. The supporting annular spring in the connecting rubber ring supports the connecting rubber ring to prevent the foaming agent from being blocked.

[0031] S6: After the filling is completed, start the hydraulic cylinder to drive the clamping rod to open, release the clamping of the feed end of the connecting rubber ring. The moving part controls the moving frame to move. When the switching gear at one end of the connecting block encounters the switching rack on the switching frame, the connecting block rotates, so that the heating block faces the connecting rubber ring in the middle. Then the hydraulic cylinder drives the clamping rod to move a relative distance, so that the heating block approaches the connecting rubber ring. After the moving frame is driven by the moving part to move, the ball at one end of the scraper enters the pushing chute and moves along the track of the pushing chute, pulling the scraper down to contact the connecting rubber ring. After the moving frame moves, the scraper can push the foaming agent in the feed end of the connecting rubber ring. After the roller leaves the pushing chute, the scraper resets. Start the hydraulic cylinder to make the heating block hot-press the feed end of the connecting rubber ring where the foaming agent is scraped off, so that the feed end is sealed.

[0032] The beneficial effects of the present invention are as follows:

[0033] 1. By setting the connecting device, it can seal between the drainage pipe and the inspection well. The gap between the drainage pipe and the connection port of the inspection well is filled with the connecting rubber ring. The inside of the connecting rubber ring can be filled with foaming agent or concrete, so that the connection between the drainage pipe and the inspection well is tight, not affected by the thermal expansion and contraction of the drainage pipe and time, reducing the possibility of water leakage. The supporting annular spring enables the middle section of the connecting rubber ring to be propped up, facilitating the complete filling of the foaming agent, so that the connection between the drainage pipe and the inspection well is tight, reducing the possibility of water leakage. It solves the technical problem that the connection between the existing inspection well and the drainage pipe is sealed by manually applying cement, which may lead to a gradual decrease in the sealing performance due to problems such as the expansion, contraction or aging of the cement, and is prone to water leakage, affecting the normal operation of the drainage system.

[0034] 2. By setting up a support device, the drainage pipe can be supported, which facilitates the filling and foaming of the foaming agent for the rubber sealing ring. By rotating the rotating disk, the position of the fixed ring can be adjusted, so that the fixed disk can adapt to inspection wells of various different diameters. At the same time, after the pushing rack moves, the support mechanism can pass through the drainage pipe, drive the rotation of the driven gear, and the support block can be inserted into the drainage pipe to complete the support of the drainage pipe. At the same time, it drives the drainage pipe to pass through the connection port of the inspection well, so that the rubber sealing ring will not be pressed by the drainage pipe at the inner wall position of the connection port, thus enabling the foaming agent to be filled evenly.

[0035] 3. By setting up a conveying device, the rubber sealing ring can be automatically filled with the foaming agent. To prevent leakage of the foaming agent at the feeding end of the rubber sealing ring during the conveying process, and to prevent the feeding end of the rubber sealing ring from being separated from the inserted conveying pipe under pressure during the conveying of the foaming agent, the relative movement of the fixed clamping blocks is used to clamp the feeding end sleeved on the inserted conveying pipe, so that the feeding end of the rubber sealing ring is fixed on the inserted conveying pipe. To seal the feeding end of the rubber sealing ring and prevent the internal foaming agent from being affected by the outside, after the switching rack meshes with the switching gear, the connecting block can be driven to turn, completing the switching between the fixed clamping blocks and the heating block, so that the heating block can face the rubber sealing ring. When the ball on the scraping plate is pressed by the track of the pushing chute, it can descend to push the foaming agent inside the feeding end of the rubber sealing ring, facilitating the thermal pressing at the feeding end to complete the sealing, thus enabling the automatic filling of the foaming agent, reducing the manual input, and solving the technical problem that the connection between the existing inspection well and the drainage pipe is sealed by manually applying cement, which requires manual operation and reduces the work efficiency.

[0065] A connection method for a connection device between an inspection well and a drainage pipe proposed by the present invention includes the following steps:

[0066] S1: First, sleeve the connecting rubber ring 2 on the connection port of the inspection well 1, and then rotate the self-locking gear 34 according to the diameter of the wellhead of the inspection well 1. The self-locking gear 34 drives the rotating disk 31 to rotate. The rotating disk 31 drives the fixed ring 33 in the limiting chute 32 to move outward through the arc-shaped groove. The inner surfaces of the plurality of fixed rings 33 can fit the outer surface of the inspection well 1, so that the fixed disk 3 can be fixed on the inspection well 1.

[0067] S2: According to the connection port position of the inspection well 1, control the fixed motor 42 on the support frame 4 to start. After the fixed motor 42 starts, it drives the rotating gear 41 to rotate. The rotation of the rotating gear 41 drives the lifting thread sleeve 43 to descend, so as to drive the connecting frame 44 to descend. After the center line of the support housing 51 and the center line of the connection port of the inspection well 1 are on the same horizontal line, after rotating the rotating rod 47 on the connecting frame 44, the rotating rod 47 drives the pushing gear 46 to rotate by means of bevel gears. After the pushing gear 46 pushes the pushing rack 45 slidably inserted on the connecting frame 44 to move horizontally, the pushing rack 45 causes the support housing 51 to penetrate through the outer surface of the inspection well 1.

[0068] S3: After sleeving the drainage pipe 11 on the outer surface of the support housing 51, the support motor 5 on the pushing rack 45 starts and drives the pushing gear disk 52 to rotate. The rotation of the pushing gear disk 52 pushes the support block 53 to move outwards, and the return spring 54 is stretched. The support block 53 is inserted into the inner wall groove of the drainage pipe 11 to complete the support of the drainage pipe 11. The pushing rack 45 moves and drives the drainage pipe 11 to be inserted into the connecting rubber ring 2.

[0069] S4: Sleeve the feeding end of the connecting rubber ring 2 on the outer surface of the plugging conveying pipe 64. By starting the pushing hydraulic cylinder 73 to drive the pushing plate 74 to move, the pushing plate 74 drives the clamping rod 75 to move relatively on the moving frame 72 through the deflecting connecting rod 76. The fixed clamping block 78 on the clamping rod 75 clamps the feeding end of the connecting rubber ring 2 on the plugging conveying pipe 64.

[0070] S5: After the conveying pump 62 on the base 6 starts, it sucks the foaming agent in the storage tank 61 and conveys it into the arc-shaped conveying pipe 63, and conveys it to the fixed connecting rubber ring 2 through the arc-shaped conveying pipe 63, so that the space inside the connecting rubber ring 2 is filled. The support ring spring inside the connecting rubber ring 2 supports the connecting rubber ring 2 to prevent the foaming agent from being blocked.

[0071] S6: After the filling is completed, start the hydraulic cylinder 73, which drives the clamping rod 75 to open, releasing the clamping on the feeding end of the connecting rubber ring 2. The moving member 71 controls the movement of the moving frame 72. When the switching gear 81 at one end of the connecting block 77 encounters the switching rack 83 on the switching frame 82, the connecting block 77 rotates, causing the heating block 8 to face the connecting rubber ring 2 in the middle. Then, the hydraulic cylinder 73 is driven to drive the clamping rod 75 to move a certain distance relative to one end, so that the heating block 8 approaches the connecting rubber ring 2. After that, the moving frame 72 moves driven by the moving member 71, and the ball 86 at one end of the scraper 84 enters the pushing chute 87 and moves along the trajectory of the pushing chute 87, pulling the scraper 84 downward to contact the connecting rubber ring 2. After the moving frame 72 moves, the scraper 84 can push the foaming agent in the feeding end of the connecting rubber ring 2. After the roller leaves the pushing chute 87, the scraper 84 resets. When the hydraulic cylinder 73 starts, the heating block 8 thermally presses the feeding end of the connecting rubber ring 2 from which the foaming agent has been scraped, closing the feeding end.
