Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the present invention discloses a connection structure of a water supply and drainage pipeline 1, which comprises two identical pipelines 1 and a pipe joint 2 for connecting the two pipelines 1, wherein the inner pipe 11 made of PVC material of the pipeline 1, a conductive film 12 coaxially covering the outer wall of the inner pipe 11, a plurality of conducting wires 13 circumferentially adhered to the outer wall of the conductive film 12, and an outer pipe 14 made of PVC material coaxially covering the outer wall of the conductive film 12, and the conducting wires 13 and the conductive film 12 are adhered together by conductive glue. A plurality of copper conducting strips 23 penetrate through the pipe joint 2, and two ends of each conducting strip 23 are respectively connected with the conducting wires 13 of the adjacent pipelines 1. When the two pipelines 1 are connected, the conductive films 12 and the conducting wires 13 of the two pipelines 1 are communicated by the conductive strips 23, so that the two pipelines 1 are electrically connected, and the real-time monitoring of the pipelines 1 can be realized.
As shown in fig. 2, since the conductive strip 23 needs to be in contact with the conductive wire 13 when the pipe joint 2 is connected to the pipeline 1, which needs to be observed manually, the pipe joint 2 includes a fixed joint 21 inserted into the pipeline 1 and a movable joint 22 coaxially adhered to the outer wall of the fixed joint 21, the movable joint 22 is made of a transparent material, and the conductive strip 23 is disposed in the fixed joint 21. The equal coaxial mounting groove 211 of having seted up in fixed joint 21 both ends, and mounting groove 211 runs through fixed joint 21 outer wall, and mounting groove 211 is all arranged in at the both ends of conducting strip 23, and mounting groove 211 is close to the lateral wall and the 11 inner walls butts of inner tube of coupling 2 axis, and movable joint 22 inner wall and the 14 outer wall butts of outer tube. At this time, after the coupling boss 2 is coupled to the pipe 1, the position of the conductive strip 23 and the conductive line 13 is observed through the movable joint 22 by rotating the coupling boss 2, and the conductive strip 23 is coupled to the conductive line 13, and the position between the conductive strip 23 and the conductive line 13 can be directly observed by naked eyes, thereby facilitating the coupling of the conductive strip 23 to the conductive line 13.
As shown in fig. 3, since the length of the installed pipe 1 is changed, when the pipe 1 is cut, the conductive strip 23 is deformed when it is subjected to a force generated by the cutting after the cutting, thereby affecting the connection of the conductive strip 23 to the lead 13. Therefore, a plurality of sliding grooves 212 are circumferentially formed in the side walls of the mounting grooves 211 perpendicular to the axis of the pipe joint 2, the number of the sliding grooves 212 is equal to the number of the conducting wires 13 and the conducting strips 23, the conducting strips 23 are located in the sliding grooves 212, and the conducting strips 23 are abutted against the side walls of the sliding grooves 212 close to the axis of the pipe joint 2. The sliding groove 212 is connected with a copper conductive block 24 in a sliding manner, the conductive block 24 is connected and conducted with the conductive bar 23, a spring 25 for driving the conductive block 24 to move in a direction of separating from the sliding groove 212 is further arranged in the sliding groove 212, and a section of the conductive block 24 extending out of the sliding groove 212 abuts against the end of the lead 13. The pair of conductive bumps 24 is used to connect the conductive wire 13 and the conductive strip 23, so that the disconnection between the two is not easy to occur.
As shown in fig. 3, since the conductive block 24 is applied with a force moving toward the pipe 1 only by means of the spring 25, the conductive block 24 cannot be kept in contact with the conductive wire 13 after the elastic coefficient of the spring 25 is reduced, thereby causing a short circuit between the conductive strip 23 and the conductive wire 13. Therefore, a plurality of driving grooves 213 communicated with the sliding groove 212 are axially formed in the outer wall of the movable joint 22, the driving rods 26 are all connected in the driving grooves 213 in a threaded manner, a wedge-shaped surface 261 is formed in the edge of the end face of each driving rod 26, which is close to the axis of the pipe joint 2, one end, away from the axis of the driving rod 26, of the wedge-shaped surface 261 inclines towards the direction away from the axis of the pipe joint 2, and the wedge-shaped surface 261 abuts against the end face, away from the. After the pipe joint 2 is connected to the pipe 1, the driving rod 26 is moved toward the axial direction of the pipe joint 2, and the position of the conductive block 24 is defined by the driving rod 26 so that the conductive block 24 is held in contact with the wire 13.
As shown in fig. 3, when the pipe 1 is cut, the conductive wire 13 is deformed, and the deformed conductive wire 13 is sunk into the inner pipe 11 or the outer pipe 14, so that the conductive block 24 cannot contact the conductive wire 13. Therefore, the end of the conductive block 24 away from the sliding groove 212 is adhered with the conductive and elastic contact 27 by using the conductive adhesive, the contact 27 is made of conductive silicon rubber, and the end of the contact 27 away from the conductive block 24 is abutted with the lead 13. At this time, when the driving rod 26 pushes the conductive block 24 to move toward the conductive wire 13, the contact head 27 is deformed to abut against the deformed conductive wire 13, thereby making the contact of the conductive bar 23 with the conductive wire 13 more stable.
As shown in fig. 3, in order to make the conductive block 24 contact with the conductive wire 13 better, a plurality of conductive bumps 271 are integrally formed on the end surface of the contact head 27 away from the conductive block 24, and the conductive bumps 271 are abutted against the end surface of the pipeline 1 and contact with the conductive wire 13. When the contact head 27 is moved towards the pipe 1, the conductive bump 271 is deformed so that the conductive bump 271 is more easily brought into contact with the conductive line 13, thereby facilitating the conduction of the conductive line 13 to the conductive strip 23.
As shown in fig. 2, when the pipe 1 and the pipe joint 2 are connected, the contact position between the pipe 1 and the pipe joint 2 needs to be sealed by a sealant, and the relative position between the pipe joint 2 and the pipe 1 needs to be adjusted before the pipe 1 and the pipe joint 2 are sealed, so that the side walls of the mounting groove 211 close to the axis of the pipe joint 2 are coaxially provided with the first sealing groove 214 in a clamping manner, the openings of the first sealing groove 214 respectively face the inner wall of the inner pipe 11 connected with the pipe joint 2, and the outer wall of the pipe joint 2 is circumferentially provided with a plurality of first sealant feeding grooves 215 communicated with the first sealing groove 214. After the relative position of the pipe joint 2 and the pipeline 1 is adjusted, sealant is introduced into the first sealant inlet groove 215, the pipeline 1 is connected with the pipe joint 2 by the sealant, and the process of arranging the sealant between the inner pipe 11 and the pipe joint 2 is more convenient.
As shown in fig. 2, in order to facilitate the connection between the movable joint 22 and the outer pipe 14, two second sealing grooves 221 are coaxially formed in the inner wall of the movable joint 22, the two second sealing grooves 221 are respectively located at two ends of the movable joint 22, and a plurality of second glue inlet grooves 222 communicated with the second sealing grooves 221 are formed in the circumferential direction of the outer wall of the pipe joint 2. And injecting sealant into the second sealing groove 221 by using second sealant, so as to close the gap between the outer wall of the outer pipe 14 and the inner wall of the movable joint 22.
As shown in fig. 2, when the sealant is injected into the first sealing groove 214 and the second sealing groove 221, the sealant will flow out from the openings of the first glue inlet and the second glue inlet that are not closed, so the plugs 28 are inserted into the openings of the first glue inlet 215 and the second glue inlet 222 that are far away from the axis of the pipe joint 2, and the plugs 28 are made of rubber and seal the first glue inlet 215 and the second glue inlet 222. Before the sealant is injected into the first sealing groove 214 and the second sealing groove 221, the plug 28 in one of the first glue inlet groove 215 and the second glue inlet groove 222 for injecting glue is pulled out, then glue is injected, and the other first glue inlet groove 215 and the second glue inlet groove 222 are sealed by the plug 28, so that the sealant does not flow away.
The implementation principle of the embodiment is as follows: the method comprises the following steps of cutting a pipeline 1 into proper lengths, sleeving a pipe joint 2 between two pipelines 1, rotating the pipe joint 2 and the other pipeline 1 respectively to enable a lead 13 of the pipeline 1 and a conducting bar 23 of the pipe joint 2 to be aligned, pulling out plugs 28 in a first glue inlet groove 215 and a second glue inlet groove 222 which are positioned at the top, pulling out plugs 28 positioned at the side faces, and injecting sealant into a first sealing groove 214 and a second sealing groove 221 through the first glue inlet groove 215 and the second glue inlet groove 222 which are positioned at the side faces respectively to enable the first sealing groove 214 and the second sealing groove 221 to be filled with the sealant. Then, the driving rod 26 is rotated towards the axial direction of the pipe joint 2 to enable the contact head 27 connected with the conductive block 24 to be tightly abutted against the end face of the pipeline 1, and then sealant is injected into the driving eraser to enable the position of the driving rod 26 to be limited.
