[0001] The invention relates to a pipeline connecting device, in particular to an anti-seepage connecting device for water supply and drainage pipes. Background Art

[0002] At present, during the construction of water supply and drainage pipes, different pipe sections need to be spliced, and the splicing positions are connected by bonding. Adhesives are used as bonding fillers to bond homogeneous pipes and fittings together to seal. The bonding connection method has the advantages of simple construction and fast curing speed, so it is widely used in water supply and drainage pipeline construction. However, this connection method has high operating requirements for construction personnel, the construction quality depends on manual experience, and the labor intensity is high. Summary of the invention

[0003] Purpose of the invention: The purpose of the present invention is to provide an anti-seepage connection device for water supply and drainage pipes with low operation requirements and low labor intensity.

[0004] Technical solution: A water supply and drainage pipe anti-seepage connection device of the present invention comprises a tubular shell, wherein an inner ring body and two adhesive rings are fixedly arranged inside the tubular shell, wherein the two adhesive rings are respectively located at two ends of the tubular shell, and the inner ring body is located between the two adhesive rings; an adhesive sealing ring groove is provided on the inner ring surface of the adhesive ring;

[0005] The two ends of the inner ring body are symmetrically provided with colloid sleeves, and the open ring opening of the colloid sleeve is sealed and fixed to the ring side of the adhesive ring; a telescopic liquid pushing rod is provided in the annular cavity of the colloid sleeve, and the telescopic liquid pushing rod includes a piston rod and a tube body storing glue, and one end of the piston rod is fixed to the surface of the ring sheet at the opposite end of the open ring opening of the colloid sleeve, and the ring sheet is reinforced by a reinforcing end sheet; a first piston is fixed to the other end of the piston rod, and the first piston is slidably arranged inside the tube body; a first one-way valve is arranged at the glue output end of the tube body, and a glue injection hole is opened on the adhesive ring, and the glue injection hole is connected to the bonding sealing ring groove and the outlet end of the first one-way valve;

[0006] The two colloid sleeves are fixedly connected as a whole through a colloid ring, and the colloid ring is composed of two wear-resistant sheets respectively connected to the corresponding colloid sleeves and a rubber ring connecting the two wear-resistant sheets; a toothed plate push tube is fixedly arranged above the side surface of the ring facing the reinforcing end sheet, and a driving gear is meshed between the two toothed plate push tubes; the driving gear is driven to rotate by a swivel mechanism arranged on the tubular housing;

[0007] The two ends of the water supply and drainage pipe are inserted into the tubular shell, and the pipe ends of the water supply and drainage pipe are against the surface of the wear-resistant plate of the colloid ring; the driving gear rotates, and the two toothed plate push tubes respectively push the reinforcing end plates to slide along the pipe wall of the water supply and drainage pipe and the inner wall of the inner ring body, and the compressed colloid stack is pressed against the inner ring body and the surface of the water supply and drainage pipe to complete the initial sealing; at the same time, the telescopic push rod is compressed, and the glue inside it enters the bonding sealing ring groove through the first one-way valve and the glue injection hole. After the glue is dry, the bonding and fixation of the anti-seepage connection device to the water supply and drainage pipe is completed.

[0008] Furthermore, a sealing groove adapted to the colloid sheath is arranged on the tube wall of the inner ring body at a position close to the adhesive ring.

[0009] Furthermore, there are multiple telescopic liquid pushing rods, which are distributed at intervals along the annular direction in the annular cavity of the colloid stack.

[0010] Furthermore, the swivel mechanism includes a swivel rotatably mounted on a tubular shell, a second ratchet is installed in a mounting groove at the lower end of the swivel shaft, the shaft of the driving gear extends upward into the interior of the inner ring body and is rotatably connected to the second ratchet rotatably arranged on the upper surface of the inner ring body; when the swivel is rotated, the second ratchet drives the driving gear to rotate.

[0011] Furthermore, the adhesive layer of the aforementioned adhesive connection method exhibits low performance in terms of peel strength, uneven pull-off strength and impact strength, which means that the adhesive connection may easily have problems when encountering certain external forces or pressure changes, and cannot be repaired. More importantly, once the pipeline connection is completed, the current technology cannot perform non-destructive testing on the sealing of its connection, which increases the risk of potential leakage in the system, which may cause failures such as water leakage, and increase the difficulty and cost of maintenance. That is, the problem of not being able to conduct contamination inspection and the inability to repair the adhesive layer in time after it is damaged.

[0012] To this end, the tubular housing is integrally provided with an attached tube, in which two toothed plate pistons are slidably provided; the toothed plate piston comprises an L-shaped plate and a second piston fixed at the end of the L-shaped plate, wherein the L-shaped plate has a toothed surface; the two second pistons and the attached tube form two liquid storage chambers, wherein the liquid storage chambers store immiscible oil and glue, wherein the oil is away from the second pistons;

[0013] The swivel mechanism also includes a torsion spring, a spring tube, a first ratchet and a gear ring sleeve. The gear ring sleeve is meshed and arranged between the two gear plate pistons. The swivel shaft extends downward and penetrates into the interior of the attached tube and is rotatably connected with the first ratchet fixed inside the gear ring sleeve. The upper end of the swivel shaft extends into the spring tube and is fixed with one end of the torsion spring in the spring tube. The torsion spring sleeve is arranged on the swivel shaft, and one end of the torsion spring is fixed below the interior of the spring tube. The spring tube is fixed on the tubular housing. The first ratchet and the second ratchet have opposite rotation driving directions.

[0014] The adhesive ring is provided with a liquid injection channel, the tubular housing is provided with a branch hole connected to the liquid storage cavity, the branch hole is communicated with the liquid injection channel, and a second one-way valve is installed inside the branch hole; the adhesive ring is provided with a diversion liquid injection channel connected to the liquid injection channel and the adhesive sealing ring groove;

[0015] When the anti-seepage connecting device is installed, the torsion spring is twisted and contracted. When the restriction on the swivel is released, the swivel rotates and resets under the action of the torsion spring, and the toothed ring sleeve is driven to rotate by the first ratchet, so that the two toothed plate pistons move along the wall of the attached tube. The oil acts on the bonding position through the second one-way valve, the injection ring channel, and the diversion injection channel, so as to detect the bonding position. If there is a gap or void at the bonding position, the oil will continue to seep out; then, the glue stored in the liquid storage chamber fills the void or void along the path of the oil, so as to achieve secondary bonding and sealing.

[0016] The present invention utilizes the torque accumulated by the torsion spring when the device is installed. After the swivel is unlocked, it drives the swivel to rotate and reset. During the reset process, the gear ring sleeve is used to perform meshing transmission of the gear plate piston, so as to push the oil and glue stored in the liquid storage chamber in sequence, so that it flows along a predetermined path to the bonding position of the water supply and drainage pipe and the device, and performs non-destructive liquid filling leakage detection on the bonding position. At the same time, the leakage defects existing in the bonding position can be timely re-filled with glue and bonded during the detection process or use process. This detection method for the bonding position is simple and convenient, does not require damage to the bonding position, and does not require manpower to detect one by one. At the same time, active repair of the defective position can be performed at the same time, which greatly reduces the work intensity and operation time, and ensures the safety and stability of the use of the water supply and drainage pipe.

[0017] Furthermore, there are multiple diversion injection channels, which are distributed at intervals along the annular direction on the adhesive ring.

[0018] Furthermore, the diverter injection channel is gate-shaped, and the two channels of the diverter injection channel are respectively connected to the bonding sealing ring groove and the glue injection hole, and a third one-way valve is provided in the channel connecting the diverter injection channel and the glue injection hole to prevent liquid from surging.

[0019] Furthermore, the other side of the L-shaped plate relative to the tooth surface is a curved surface adapted to the wall of the attached pipe.

[0020] Furthermore, a hand wheel is installed on the upper end of the rotating shaft of the rotating body.

[0021] Furthermore, the tubular shell includes an upper shell and a lower shell, and the upper shell and the lower shell are fixedly connected by bolts.

[0022] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: after the water supply and drainage pipes are pulled together, the present invention can quickly compress the colloid sleeve and the telescopic push rod and pull the colloid at the annular butt joint gap, so that while the colloid is used to perform necessary sealing on the connection position, the glue can be injected between the adhesive ring and the water supply and drainage pipe, thereby achieving bonding and fixation between the device and the water supply and drainage pipe. The assembly operation process of the device is simple and convenient, with low operating requirements for construction personnel and low labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A glue injection hole 143 is provided inside the adhesive ring 14 and on a side of the adhesive sealing ring groove 144 close to the axis. The glue injection hole 143 is connected to the adhesive sealing ring groove 144 .

[0036] The inner ring body 15 is provided with a colloid sleeve 152 symmetrically arranged along the center, and the colloid sleeve 152 is a ring-shaped foldable and compressible colloid structure.

[0037] A plurality of telescopic push rods 1521 are arranged in the annular cavity of the colloid stack 152 corresponding to the glue injection hole 143. The telescopic push rods 1521 are a telescopic structure, which includes a piston rod and a tube body storing glue. The glue output end of the tube body is equipped with a first one-way valve, and the end is fixedly connected to the port of the glue injection hole 143.

[0038] One end of the piston rod is fixed to the surface of the ring sheet at the opposite end of the open ring opening of the colloid stack 152, and the ring sheet is reinforced by the reinforcing end sheet 1522 to ensure that it can move along the water supply and drainage pipe and the inner wall of the inner ring body 15. The other end of the piston rod is fixed with a first piston, which is slidably arranged inside the tube body.

[0039] The two colloid sleeves 152 are fixedly connected as a whole through a colloid ring 1523. The colloid ring 1523 consists of two wear-resistant plates respectively connected to the corresponding colloid sleeves 152 and a rubber ring connecting the two wear-resistant plates. The colloid ring 1523 needs to be set at the connecting position between the two water supply and drainage pipes when connecting.

[0040] A toothed plate push tube 153 is fixedly disposed above the side surface of the reinforcing end piece 1522 facing the ring, and the two toothed plate push tubes 153 are centrally symmetrical, and a driving gear 134 is meshed between the two toothed plate push tubes 153; the driving gear 134 is driven to rotate by a rotating mechanism disposed on the tubular housing. Specifically,

[0041] The swivel mechanism includes a swivel 13 rotatably mounted on the upper shell 11, a second ratchet 133 is installed in the mounting groove at the lower end of the rotating shaft of the swivel 13, the rotating shaft of the driving gear 134 extends upward into the interior of the inner ring body 15 and is rotatably connected to the second ratchet 133 rotatably set at the center position of the upper surface of the inner ring body 15; when the swivel 13 is rotated, the second ratchet 133 drives the driving gear 134 to rotate.

[0042] When in use, the two ends of the water supply and drainage pipe are inserted into the tubular housing, and the ends of the water supply and drainage pipe are against the wear-resistant sheet surface of the colloid ring 1523; the rotating body 13 is manually rotated, and the driving gear 134 is driven to rotate through the second ratchet 133, and the driving gear 134 engages the transmission tooth plate push tube 153 to move to both sides, and the two tooth plate push tubes 153 push the reinforcing end pieces 1522 to slide along the pipe wall of the water supply and drainage pipe and the inner wall of the inner ring body 15, and the reinforcing end pieces 1522 compress the colloid stack 152 when sliding, and the compressed colloid stack 152 is pressed against the inner ring body 15 and the surface of the water supply and drainage pipe to complete the preliminary sealing. At the same time, the telescopic push rod 1521 is compressed, and the glue in it enters the bonding seal ring groove 144 through the first one-way valve and the glue injection hole 143. After the glue is dry, the anti-seepage connection device is bonded and fixed to the water supply and drainage pipe.

[0043] In summary, after the water supply and drainage pipes are pulled to connect, the present invention can quickly perform compression on the colloid stack 152 and the telescopic push rod 1521 and pull the colloid ring 1523 toward the connecting gap in a manually driven transmission mode, so that while the colloid is used to perform necessary sealing on the connection position, the glue is injected between the adhesive ring 14 and the water supply and drainage pipe, thereby achieving bonding and fixation between the device and the water supply and drainage pipe. The device assembly operation process is simple and convenient, with low operation requirements and low labor intensity.

[0044] Example 2

[0045] This embodiment 2 is further improved on the basis of embodiment 1.

[0046] The upper surface of the upper shell 11 is integrally provided with an auxiliary tube 111, and two toothed plate pistons 112 are slidably provided in the auxiliary tube 111 and are symmetrically arranged along the axis center. The toothed plate piston 112 includes an L-shaped plate and a second piston fixed to the end of the L-shaped plate, the L-shaped plate has a toothed surface, and the other side of the L-shaped plate relative to the toothed surface is an arc surface adapted to the wall of the auxiliary tube 111.

[0047] The two second pistons and the attached tube 111 form two liquid storage chambers 1111, and the liquid storage chambers 1111 store immiscible oil and glue, wherein the oil is far away from the second pistons. The oil can also be replaced by other liquid materials that are immiscible with the glue.

[0048] A liquid injection annular channel 141 is provided at the center of the adhesive ring 14, and a branch hole connected to the liquid storage chamber 1111 is provided on the tubular housing, the branch hole is communicated with the liquid injection annular channel 141, and a second one-way valve is installed inside the branch hole. A plurality of gate-shaped shunt liquid injection channels 142 are provided along the annular interval on the adhesive ring 14, and the two channels of the shunt liquid injection channel 142 are respectively communicated with the adhesive sealing ring groove 144 and the glue injection hole 143, and a third one-way valve is provided in the channel connecting the shunt liquid injection channel 142 and the glue injection hole 143 to prevent liquid from surging.

[0049] The first, second and third one-way valves mentioned above are all marked 16 in the drawings.

[0050] A hand wheel is installed at the upper end of the rotating shaft of the swivel 13. The swivel mechanism also includes a torsion spring 131, a spring tube, a first ratchet 1321 and a toothed ring sleeve 132, the toothed ring sleeve 132 is meshedly arranged between the two toothed plate pistons 112, the rotating shaft of the swivel 13 extends downward to penetrate the interior of the attached tube 111, and is rotationally connected with the first ratchet 1321 fixed inside the toothed ring sleeve 132, and the upper end of the rotating shaft of the swivel 13 extends out of the attached tube 111 into the spring tube and is fixed with one end of the torsion spring 131 in the spring tube, the torsion spring 131 is sleeved on the rotating shaft of the swivel 13, and one end of the torsion spring 131 is fixed below the interior of the spring tube, and the spring tube is fixed on the tubular housing; the first ratchet 1321 and the second ratchet 133 have opposite rotation driving directions.

[0051] When installing the anti-seepage connection device, the swivel 13 is rotated and the torsion spring 131 is twisted. When the restriction on the swivel 13 is released, the swivel 13 rotates and resets under the action of the torsion spring 131, and the reset swivel 13 drives the toothed ring sleeve 132 to rotate through the first ratchet 1321, and the rotating toothed ring sleeve 132 will engage the transmission toothed plate piston 112 at both ends of the attached tube 111, so that the two toothed plate pistons 112 move along the tube wall of the attached tube 111, and the moving toothed plate piston 112 will push the oil stored in the liquid storage chamber 1111 into the injection annular channel 141 through the second one-way valve, and then enter the diverter injection channel 142 along the injection annular channel 141, and finally the side surface and end surface of the ring will act on the bonding position, so as to realize the detection of the bonding position. If there is a gap or void after bonding at the bonding position, the oil will seep out through the gap or void under the continuous pressure of the tooth plate piston 112, and as the oil continues to seep out, the glue stored in the liquid storage chamber 1111 fills the gap or void along the path of the oil, thereby achieving secondary bonding and sealing of the gap or void. The working process is the same as above when the bonding position is accidentally separated by strong stretching.

[0052] In summary, the present invention utilizes the torque accumulated by the torsion spring 131 when the device is installed, and after the swivel 13 is unlocked, it drives the swivel 13 to rotate and reset, and in the resetting process, cooperates with the toothed ring sleeve 132 to perform the meshing transmission of the toothed plate piston 112, so as to push the separated stored oil and glue inside the liquid storage chamber 1111, so that it flows along the preset channel to the bonding position of the water supply and drainage pipe and the device, and performs non-destructive liquid filling leakage detection on the bonding position. At the same time, the leakage defects existing in the bonding position can be timely re-filled with glue and bonded during the detection process or use process. This detection method for the bonding position is simple and convenient, does not need to damage the bonding position, does not need to invest manpower to detect one by one, and can simultaneously perform active repairs on the defective position, greatly reducing the work intensity and operation time of the staff, and ensuring the safety and stability of the use of the water supply and drainage pipe.

[0053] Working principle of the present invention:

[0054] First, pull the two ends of the water supply and drainage pipe, and insert the two ends of the water supply and drainage pipe into the interior of the device, so that the pipe ends of the water supply and drainage pipe are against the surface of the wear-resistant plate of the colloid ring 1523. After ensuring stability, manually rotate the swivel 13 so that while twisting the torsion spring 131, it cooperates with the second ratchet 133 to drive the driving gear 134 to rotate. The rotating driving gear 134 will move toward the transmission toothed plate push tube 153 on both sides in a meshing transmission manner, and then the toothed plate push tube 153 will push the reinforcing end piece 1522 to slide along the pipe wall and the inner wall of the inner ring body 15, and the reinforcing end piece 1522 will push the colloid stack 152 when sliding, so that it is gradually compressed and protruded, and pressed against the surface of the inner ring body 15 and the water supply and drainage pipe. At the same time, the compressed colloid stack 152 will pull and drag the colloid ring 1523, so that the colloid ring 1523 is pressed against the gap where the water supply and drainage pipes are connected, thereby completing the preliminary sealing of the water supply and drainage pipes. While compressing the colloid stack 152, the telescopic push rod 1521 will be compressed, and then the glue stored inside the telescopic push rod 1521 will break through the restriction of the first one-way valve, forcing the first one-way valve to open, and then the glue will be injected into the glue injection hole 143, and then enter the adhesive sealing ring groove 144 through the glue injection hole 143, and quickly fill the adhesive sealing ring groove 144. After the glue dries, the device can be bonded and fixed to the water supply and drainage pipe.

[0055] When the restriction on the swivel 13 is released, the swivel 13 will rotate and reset under the action of the torsion spring 131, and the reset swivel 13 will cooperate with the first ratchet 1321 to drive the toothed ring sleeve 132 to rotate, and the rotating toothed ring sleeve 132 will engage the transmission toothed plate piston 112 at both ends of the attached tube 111, so that the toothed plate piston 112 moves along the tube wall of the attached tube 111, and the moving toothed plate piston 112 will push the oil and glue stored in the liquid storage chamber 1111 to break through the restriction of the second one-way valve, enter the interior of the injection annular channel 141 through the second one-way valve, and enter the interior of the diverter injection channel 142 along the injection annular channel 141, and finally act on the bonding position by the side surface and end surface of the ring, so as to realize the detection of the bonding position. In the gaps or voids after bonding, the oil will seep out through the gaps or voids under the continuous pressure of the tooth plate piston 112, and as the oil continues to seep out, the glue stored in the liquid storage chamber 1111 will enter the injection ring 141 and the diversion injection channel 142 along the path of the oil, and fill the gaps or voids along the path of oil seepage, thereby filling the gaps or voids with glue to achieve secondary bonding and sealing of the gaps or voids. If the bonding position is accidentally separated by strong stretching during use, the above-mentioned secondary sealing method will be used. After the water supply and drainage pipe anti-seepage connection device is automatically reset after stretching, the separation position will be filled with glue again to achieve re-bonding and fixation of the water supply and drainage pipe and the water supply and drainage pipe anti-seepage connection device.
