Description

Technical Field

[0001] The invention relates to the technical field of rainwater and sewage discharge, and in particular to a device for integrated control of rainwater and sewage discharge. Background Art

[0002] The municipal underground pipeline network is the "blood vessel" of the urban drainage system. When the rainwater and sewage pipelines are upgraded due to engineering renovation, or when there is a requirement to switch and overhaul the pipelines during use, it is necessary to drain or block the rainwater and sewage pipes that already have water. However, it is very difficult to seal the pipe openings that cannot be pumped out. Based on this, pipeline airbags are often used to achieve water blocking.

[0003] Airbag plugging is an airbag made of high-quality rubber in the same shape as the pipeline. The airbag is expanded by inflation. When the gas pressure in the water-blocking airbag reaches the specified requirement, the water-blocking airbag fills the entire pipeline section. The friction between the pipeline plugging airbag wall and the pipeline is used to block the leakage, thereby achieving the purpose of quickly blocking the water flow in the target pipe section and preventing water from seeping. At the same time, it also solves the problem of not being able to quickly remove the blockage when there is water at the pipe mouth. However, due to various external interferences, the automatic gas transmission system of the airbag is powered off and cannot work. It takes time to repair electricity. If there are staff working in the pipeline, the loss is inevitable. Secondly, the airbag is not well stored and there is no rule, which leads to the obstruction of normal drainage. At the same time, the surface of the airbag flushed by the water flow is increased, which reduces the service life of the airbag. Summary of the invention

[0004] The object of the present invention is to provide a device for integrated control of rainwater and sewage discharge to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a device for integrated control of rainwater and sewage discharge, comprising a drainage pipe buried underground, an electrical cabinet, a manual cabinet, and an air bag, the electrical cabinet and the manual cabinet being arranged on the ground, at least a pair of fixings being installed on the inner wall of the drainage pipe, the air bag being arranged in the drainage pipe, the air bag being connected to the fixings, an air supply hose being connected to the air bag, an automatic air supply assembly being arranged in the electrical cabinet, a manual air supply assembly being arranged in the manual cabinet, both the automatic air supply assembly and the manual air supply assembly being connected to the air supply hose, a folding assembly being connected to each pair of the fixings, the folding assembly being located inside the air bag, and the folding assembly folds the air bag.

[0006] Furthermore, each pair of the fixing members extends into the interior of the airbag, and each of the folding components includes a pair of upper storage rods, one end of the two upper storage rods is rotatably connected to a pair of fixing members respectively, a torsion spring is installed at the rotation connection between each upper storage rod and the fixing member, the other end of the two upper storage rods is rotatably connected to an upper adapter, one end of the two upper adapters is rotatably connected to a middle storage rod, the other end of the two middle storage rods is rotatably connected to a middle adapter, one end of the two middle adapters is rotatably connected to a lower storage rod, and one end of a pair of lower storage rods is rotatably connected to the same lower adapter. If The drainage pipe needs to be blocked, and the automatic air supply component inflates the airbag, which gradually expands. During the expansion process, the airbag drives all the folding components to move, and the connecting action of the linkage rod enables all the folding components to move synchronously, so that the airbag changes evenly and synchronously as a whole during the deployment process, thereby avoiding water trapping in the middle of the airbag and reducing the contact surface between the airbag and the drainage pipe and losing the sealing performance. At the same time, the folding component plays an internal support role during the deployment of the airbag, preventing the water in the drainage pipe from impacting the airbag and avoiding the situation where the airbag cannot accurately fit the inner wall of the drainage pipe.

[0007] Furthermore, a hook spring is connected between each of the upper adapter, the middle adapter and the lower adapter and the inner wall of the airbag, and the upper adapters with relatively opposite positions in different folding assemblies are connected to the same linkage rod. The setting method of the linkage rods in several of the middle adapters or the lower adapters is the same as the setting method of the linkage rod on the upper adapter. When the airbag needs to be stored, the automatic gas delivery assembly extracts the gas in the airbag through the air supply hose, the airbag becomes relaxed, and the torsion spring drives the upper storage rod to retract inward. When the lower adapter is stored upward, the lower storage rod pushes the lower position of the airbag outward first. After the lower adapter passes the maximum distance stretched by the two lower storage rods, the bottom of the airbag rises with the lower adapter under the action of the hook spring, so that during the storage process of the airbag, the two sides of the airbag are always stored inward, and the bottom of the airbag is stored last.

One end of each separator ring close to the inner wall of the airbag is fixed to the airbag. After the airbag is inflated, the surfaces of all the separator rings exposed by the airbag are in contact with the inner wall of the drainage pipe. Since the drainage pipe discharges rainwater and sewage for a long time, silt is often attached to the inner wall of the pipe. The separator ring cuts the silt on the inner wall of the pipe into several sections and squeezes out part of the water in the silt, so that the silt cannot flow, forming a non-shear fluid state. The silt is used to fill the contact surface gap between the airbag and the drainage pipe, further enhancing the sealing of the airbag to the drainage pipe.

The operator holds the handles at both ends of the chain with both hands and pulls the chain repeatedly. The chain drives the sprocket wheel to rotate repeatedly, and the active bevel gear rotates synchronously with the sprocket wheel. The active bevel gear drives the front bevel gear and the rear bevel gear to rotate repeatedly. Since the one-way ratchet mechanism can only make the front bevel gear and the rear bevel gear drive the transmission shaft to rotate in one direction respectively, and at the same time the front bevel gear and the rear bevel gear rotate in opposite directions, even if the active bevel gear repeatedly reverses direction, the transmission shaft rotates continuously in one direction.

[0011] Furthermore, a separation disk is slidably provided at one end of the transmission shaft, and a plurality of impact blocks are provided at one end of the separation disk close to the rear bevel gear, and a plurality of bells are provided at the position corresponding to the impact block in the artificial cabinet, and a plurality of balls are rollingly installed on the end of the separation disk away from the impact block, and a ball groove disk is provided at the end of the separation disk where the balls are provided, and the ball groove disk is rotatably installed in the artificial cabinet, a ball groove is provided on the ball groove disk, and the ball is located in the ball groove, and a tension spring is provided between the separation disk and the ball groove disk, and a bearing is provided at the connection between the tension spring and the separation disk and the ball groove disk, and the transmission shaft drives the separation disk to rotate, and the tension spring makes the separation disk and the ball groove disk fit tightly, and the separation disk drives the ball groove disk to rotate through the balls, and the ball groove disk drives the crank to rotate, and the crank drives the piston rod of the cylinder to move up and down through the connecting rod, thereby driving the cylinder to inflate and deflate the airbag.

At this time, the operator is still pulling the chain, and the separation plate is still rotating until the torque of the separation plate rotation overcomes the tension of the tension spring, the ball exceeds the ball groove and rotates, the separation plate moves toward the transmission shaft, and the impact block moves to the range where it can hit the bell, and the bell is knocked to make a sound, reminding the operator to stop working.

By stepping on the pedal, the connection relationship between the cylinder and the air bag is changed, thereby realizing the function of manually inflating and deflating the air bag.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] 1. By setting up the folding assembly, the airbag drives all the folding assemblies to move during the expansion process.

[0030] Three pairs of fixing members 4 extend into the interior of the airbag 3, and the three folding components include a pair of upper storage rods 601, one end of the two upper storage rods 601 is rotatably connected to a pair of fixing members 4 respectively, and a torsion spring is installed at the rotation connection between each upper storage rod 601 and the fixing member 4, and the other ends of the two upper storage rods 601 are rotatably connected to an upper adapter 801, one end of the two upper adapters 801 is rotatably connected to a middle storage rod 602, and the other ends of the two middle storage rods 602 are rotatably connected to the middle adapter 802, and one end of the two middle adapters 802 is rotatably connected to a lower storage rod 7, and one end of a pair of lower storage rods 7 is rotatably connected to the same lower adapter 803 Connection. If the drainage pipe needs to be blocked, the automatic air supply component inflates the airbag 3, and the airbag 3 gradually expands. During the expansion process, the airbag 3 drives all the folding components to move. The connecting effect of the linkage rod 10 enables all the folding components to move synchronously, so that the airbag 3 changes uniformly and synchronously as a whole during the deployment process, avoiding the phenomenon of water being trapped in the middle of the airbag 3, avoiding the reduction of the contact surface between the airbag 3 and the drainage pipe and the loss of sealing. At the same time, the folding component plays an internal support role during the deployment of the airbag 3, preventing the water in the drainage pipe from impacting the airbag 3, and avoiding the situation where the airbag 3 cannot accurately fit the inner wall of the drainage pipe.

[0031] A hook spring 9 is connected between each upper adapter 801, the middle adapter 802 and the lower adapter 803 and the inner wall of the airbag 3. The upper adapters 801 with opposite positions in different folding components are connected to the same linkage rod 10.

Each separation ring 11 is made of flexible material. One end of each separation ring 11 close to the inner wall of the airbag 3 is fixed to the airbag 3. When the airbag 3 needs to be stored, the automatic gas delivery component extracts the gas in the airbag 3 through the gas supply hose 5, and the airbag 3 becomes loose. The torsion spring drives the upper storage rod 601 to retract inward, and when the lower adapter 803 is stored upward, the lower storage rod 7 pushes the lower position of the airbag 3 outward first, and the lower adapter 8 03 After crossing the maximum distance opened by the two lower storage rods 7, the bottom of the airbag 3 rises along with the lower adapter 803 under the action of the hook spring 9, so that during the storage process of the airbag 3, the two sides of the airbag 3 are always stored inward, and the bottom of the airbag 3 is stored last. By regularly storing the airbag 3, the cross-sectional area of ​​the airbag 3 after storage can be effectively reduced, leaving enough drainage pipe surface to reduce the blockage of water flow. After the airbag 3 is inflated, all the separating rings 11 expose the surface of the airbag 3 and contact the inner wall of the drainage pipe. Since the drainage pipe discharges rainwater and sewage for a long time, silt is often attached to the inner wall of the pipe. The separating ring 11 cuts the silt on the inner wall of the pipe into several sections and squeezes out part of the water in the silt, so that the silt cannot flow, forming a non-shear fluid state. The silt is used to fill the contact surface gap between the airbag 3 and the drainage pipe, further enhancing the sealing of the airbag 3 to the drainage pipe.

The transmission shaft 19 is rotatably installed in the artificial cabinet 2. A front bevel gear 15 and a rear bevel gear 16 are relatively provided on the transmission shaft 19. The front bevel gear 15 and the rear bevel gear 16 are both meshed with the active bevel gear 14 for transmission. A one-way ratchet mechanism is provided at the connection between the front bevel gear 15 and the rear bevel gear 16 and the transmission shaft 19. The one-way ratchet mechanism at the front bevel gear 15 The transmission direction of the ratchet mechanism is opposite to the transmission direction of the one-way ratchet mechanism at the rear bevel gear 16. If the power of the electrical cabinet 1 fails, the airbag 3 needs to be inflated and deflated manually. The operator holds the handles at both ends of the chain 12 with both hands and repeatedly pulls the chain 12. The chain 12 drives the sprocket wheel 13 to rotate repeatedly, and the active bevel gear 14 rotates synchronously with the sprocket wheel 13. The active bevel gear 14 drives the front bevel gear 15 and the rear bevel gear 16 to rotate repeatedly. Since the one-way ratchet mechanism can only make the front bevel gear 15 and the rear bevel gear 16 drive the transmission shaft 19 to rotate in one direction respectively, and at the same time the front bevel gear 15 and the rear bevel gear 16 rotate in opposite directions, even if the active bevel gear 14 repeatedly reverses rotation, the transmission shaft 19 continuously rotates in one direction.

[0033] A separation disc 20 is slidably provided at one end of the transmission shaft 19, and a plurality of impact blocks 18 are provided at one end of the separation disc 20 close to the rear bevel gear 16.

The upper end of the cylinder 25 is connected to an intake branch pipe and a return branch pipe. The intake branch pipe is connected to the intake pipe 26, and the return branch pipe is connected to the return pipe 27. Check valves are provided on the intake pipe 26, the return pipe 27, the intake branch pipe, and the return branch pipe. The setting direction of the check valve on the intake pipe 26 and the intake branch pipe is opposite to the setting direction of the check valve on the return pipe 27 and the return branch pipe.

[0034] The transmission shaft 19 drives the separation plate 20 to rotate, and the tension spring 22 makes the separation plate 20 and the bead groove plate 21 fit tightly. The separation plate 20 drives the bead groove plate 21 to rotate through the ball bearing, and the bead groove plate 21 drives the crank 23 to rotate. The crank 23 drives the piston rod of the cylinder 25 to move up and down through the connecting rod 24, driving the cylinder 25 to inflate and deflate the airbag 3. When the gas in the airbag 3 is full or exhausted, the cylinder 25 can no longer pump and discharge the gas, and the connecting rod 24 makes the crank 23 unable to rotate, and the bead groove plate 21 stops rotating. At this time, the operator is still pulling the chain 12, and the separation plate 20 is still rotating until the torque of the separation plate 20 rotation overcomes the tension of the tension spring 22, the ball bearing goes out of the ball groove and rotates, the separation plate 20 moves toward the transmission shaft 19, and the impact block 18 moves to the range where it can hit the bell 17. The bell 17 is knocked and makes a sound, reminding the operator to stop working.

[0035] The manual gas transmission assembly includes a gas distribution plate 31 and a connecting plate 29. A partition plate 32 is rotatably arranged inside the gas distribution plate 31. The partition plate 32 divides the interior of the gas distribution plate 31 into two isolated chambers. A tooth groove is provided on the partition plate 32. The connecting plate 29 is rotatably arranged in the artificial cabinet 2. A fan gear 30 is provided on the connecting plate 29. The fan gear 30 is meshed with the tooth groove. A pedal 28 is also rotatably arranged on the connecting plate 29. One end of the pedal 28 extends out of the artificial cabinet 2.

The upper end of the gas distribution plate 31 is connected to the air supply hose 5, and the lower end of the gas distribution plate 31 is connected to the atmosphere. The artificial cabinet 2 is provided with a position corresponding to the pedal 28. There is a trapezoidal through groove, and a torsion spring is provided at the rotating connection between the connecting plate 29 and the manual cabinet 2. The operator steps on the pedal 28 and clamps the pedal 28 under the trapezoidal through groove. The pedal 28 drives the connecting plate 29 to swing, and the connecting plate 29 drives the partition 32 to rotate in the gas distribution plate 31 through the fan gear 30. When the return air pipe 27 is connected with the air supply hose 5 and the air intake pipe 26 is connected with the atmosphere, the cylinder 25 moves to inflate the airbag 3. When the return air pipe 27 is connected with the atmosphere and the air intake pipe 26 is connected with the air supply hose 5, the cylinder 25 moves to extract the gas in the airbag 3. By stepping on the pedal 28, the connection relationship between the cylinder 25 and the airbag 3 is changed, thereby realizing the function of manually inflating and deflating the airbag 3.

[0036] The working principle of the present invention is as follows: when using the device for integrated control of rainwater and sewage discharge in the present invention, the automatic air delivery component inflates the airbag 3, and the airbag 3 gradually expands. During the expansion process, the airbag 3 drives all the folding components to move, and the connecting effect of the linkage rod 10 enables all the folding components to move synchronously, so that the airbag 3 changes uniformly and synchronously as a whole during the deployment process, thereby avoiding the phenomenon of water being trapped in the middle of the airbag 3 and avoiding the loss of sealing due to the reduction of the contact surface between the airbag 3 and the drainage pipe. At the same time, the folding component plays an internal support role during the deployment of the airbag 3, preventing the water in the drainage pipe from impacting the airbag 3 and avoiding the situation where the airbag 3 cannot accurately fit the inner wall of the drainage pipe. When the bag 3 is stored, the automatic air delivery component extracts the gas in the air bag 3 through the air supply hose 5, the air bag 3 becomes relaxed, and the torsion spring drives the upper storage rod 601 to retract inward. When the lower adapter 803 is stored upward, the lower storage rod 7 pushes the lower position of the air bag 3 outward first. After the lower adapter 803 passes the maximum distance stretched by the two lower storage rods 7, the bottom of the air bag 3 rises along with the lower adapter 803 under the action of the hook spring 9, so that during the storage process of the air bag 3, the two sides of the air bag 3 are always stored inward, and the bottom of the air bag 3 is stored last. By regularly storing the air bag 3, the cross-sectional area of ​​the air bag 3 after storage can be effectively reduced, leaving enough drainage pipe surface, thereby reducing blockage of water flow.

[0037] After the airbag 3 is inflated, all the dividing rings 11 expose the surface of the airbag 3 and contact the inner wall of the drainage pipe. Since the drainage pipe discharges rainwater and sewage for a long time, silt is often attached to the inner wall of the pipe. The dividing ring 11 cuts the silt on the inner wall of the pipe into several sections and squeezes out part of the water in the silt, making it impossible for the silt to flow, forming a non-shear fluid state. The silt is used to fill the contact surface gap between the airbag 3 and the drainage pipe, further enhancing the sealing performance of the airbag 3 to the drainage pipe.

[0038] If the power of the electrical cabinet 1 fails, the airbag 3 needs to be inflated and deflated manually. The operator holds the handles at both ends of the chain 12 with both hands and repeatedly pulls the chain 12. The chain 12 drives the sprocket wheel 13 to rotate repeatedly, and the active bevel gear 14 rotates synchronously with the sprocket wheel 13. The active bevel gear 14 drives the front bevel gear 15 and the rear bevel gear 16 to rotate repeatedly. Since the one-way ratchet mechanism can only make the front bevel gear 15 and the rear bevel gear 16 drive the transmission shaft 19 to rotate in one direction respectively, and at the same time the front bevel gear 15 and the rear bevel gear 16 rotate in opposite directions, even if the active bevel gear 14 repeatedly reverses and rotates, the transmission shaft 19 rotates continuously in one direction, and the transmission shaft 19 drives the separation plate 20 to rotate, and the tension spring 22 makes the separation plate 20 and the bead groove The disc 21 fits tightly, and the separation disc 20 drives the bead groove disc 21 to rotate through the ball, and the bead groove disc 21 drives the crank 23 to rotate. The crank 23 drives the piston rod of the cylinder 25 to move up and down through the connecting rod 24, driving the cylinder 25 to inflate and deflate the airbag 3. When the gas in the airbag 3 is full or exhausted, the cylinder 25 can no longer pump out the gas, and the connecting rod 24 makes the crank 23 unable to rotate, and the bead groove disc 21 stops rotating. At this time, the operator is still pulling the chain 12, and the separation disc 20 is still rotating until the torque of the separation disc 20 rotation overcomes the tension of the tension spring 22, and the ball rotates out of the ball groove, and the separation disc 20 moves toward the transmission shaft 19. The impact block 18 moves to the range where it can hit the bell 17, and the bell 17 is knocked to make a sound, reminding the operator to stop working.

[0039] The operator steps on the pedal 28 and clamps the pedal 28 under the trapezoidal groove. The pedal 28 drives the connecting plate 29 to swing, and the connecting plate 29 drives the partition 32 to rotate in the air distribution plate 31 through the fan gear 30. When the return air pipe 27 is connected with the air supply hose 5 and the intake pipe 26 is connected with the atmosphere, the cylinder 25 moves to inflate the airbag 3. When the return air pipe 27 is connected with the atmosphere and the intake pipe 26 is connected with the air supply hose 5, the cylinder 25 moves to extract the gas in the airbag 3. By stepping on the pedal 28, the connection relationship between the cylinder 25 and the airbag 3 is changed, thereby realizing the function of manually inflating and deflating the airbag 3.
