DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Embodiment one

[0033] Please refer to Figures 1-7 The present application provides a technical solution: a pre-buried PVC-C same-layer drainage connecting device, which comprises a heat fusing device 1, a pipeline 11 and a tee pipe 12. The heat fusing device 1 comprises a heat fusing column 13, which is located on both sides of the heat fusing device 1. The heat fusing device 1 is connected with the pipeline 11 and the tee pipe 12 through heating.

[0034] The cutting mechanism 2 is located at one end of the hot melting device 1, the cutting mechanism 2 comprises a heat insulation ring 21 arranged outside the hot melting column 13, a plurality of cutter grooves 22 are arranged outside the heat insulation ring 21, each cutter groove 22 is arranged in equidistant annular arrangement, a cutter 23 is arranged inside the cutter groove 22, and the cutter 23 is in sliding connection inside the cutter groove 22.

[0035] The trigger mechanism 3 is located between the hot melting column 13 and the heat insulation ring 21, the trigger mechanism 3 comprises a spring 31 fixedly connected to the outer wall of the hot melting device 1, the spring 31 is fixedly connected with a blocking ring 32 away from one end of the hot melting device 1, and the blocking ring 32 is in sliding connection with the hot melting device 1.

[0036] The PVC pipeline 11 and the three-way pipe 12 are heated to a molten state by the electric heating element inside the hot melting device 1, when the pipeline 11 and the three-way pipe 12 are connected, the contact surface of the pipeline 11 and the three-way pipe 12 is fused by molecular interpenetration, and after cooling, a seamless connection is formed, the sealing property of the connection between the pipeline 11 and the three-way pipe 12 is ensured, and the three-way pipe 12 realizes flow splitting and flow combining by changing the fluid path.

[0037] In use, the pipeline 11 and the three-way pipe 12 are heated through the hot melting columns 13 at both ends of the hot melting device 1, the electric telescopic rod 24 is electrified through the trigger mechanism 3, the electric telescopic rod 24 drives the cutter 23 inside the cutting mechanism 2 to cut the end of the pipeline 11, and the end burr and waste of the pipeline 11 are removed, so that the burr is prevented from entering the pipeline 11 and adhering to the connection of the pipeline 11, and the pipeline 11 is prevented from being blocked by the burr.

[0038] The cutting mechanism 2 comprises an electric telescopic rod 24 arranged on the outer wall of the hot melting device 1, the hot melting device 1 is fixedly connected with the electric telescopic rod 24, and the output end of the electric telescopic rod 24 is fixedly connected with the cutter 23.

[0039] When the electric telescopic rod 24 is powered on, the output end of the electric telescopic rod 24 drives the cutter 23 to move, and the cutter 23 can enter the inside of the heat preservation ring 21 through the cutter groove 22 when moving, and the cutter 23 performs annular cutting on the end of the pipeline 11. Since the pipeline 11 cannot rotate when being heated by the hot melting device 1, the pipeline 11 is cut by multiple cutters 23 in a segmented and combined manner, without the need to rotate the pipeline 11, and the heated pipeline 11 is easier to cut, avoiding the deviation that may occur during manual cutting, improving the quality and efficiency of the pipeline 11 cutting, and the waste after cutting is located between the pipeline 11 and the blocking ring 32. After the pipeline 11 is moved out, the spring 31 is reset to lift the blocking ring 32, and the waste is ejected from the heat preservation ring 21 by the inertia of the blocking ring 32, realizing automatic cleaning of the waste without additional manual processing, saving time and labor costs, and preparing for the next heating of the pipeline 11, ensuring the continuity and smoothness of the work of the hot melting device 1.

[0040] The cutter 23 is fixedly connected with a first blocking rod 25 and a second blocking rod 26 on the outer wall, the first blocking rod 25 and the second blocking rod 26 are located on both sides of the cutter 23, and the first blocking rod 25 is located at an end of the second blocking rod 26 away from the heat preservation ring 21.

[0041] When the electric telescopic rod 24 pushes the cutter 23 to approach the pipeline 11, the first blocking rod 25 on the outer wall of the cutter 23 pushes the second blocking rod 26 of the adjacent cutter 23, and so on, so that the pushing of the cutters 23 is coherent and synchronous, effectively ensuring that all cutters 23 act at the same time, and then ensuring that the pipeline 11 is accurately and completely annularly cut, improving the cutting quality and efficiency.

[0042] Similarly, when the electric telescopic rod 24 is retracted, the output end of the electric telescopic rod 24 pulls the cutter 23 back, the second blocking rod 26 on the outer wall of the cutter 23 drives the first blocking rod 25 of the adjacent cutter 23 to move, and then drives the adjacent cutter 23 to move, ensuring that each cutter 23 can return to the initial position according to the predetermined trajectory and speed, avoiding the situation that part of the cutters 23 cannot be retracted to the position or the retraction speed is inconsistent, and preparing for the next cutting operation accurately.

[0043] A limiting groove 27 is formed in the surface of the cutter 23, a limiting rod 28 is fixedly connected on the outer wall of the hot melting device 1, the limiting rod 28 is located in the limiting groove 27, the limiting rod 28 and the limiting groove 27 are in sliding connection, and two gaskets 29 are fixedly connected on the outer wall of the limiting rod 28, and the two gaskets 29 are located on both sides of the cutter 23.

[0044] When the cutter 23 moves, the cutter 23 is limited by the gaskets 29 at both ends, and when the cutter 23 slides, the opposite limiting rods 28 slide inside the limiting grooves 27 provided in the cutter 23, on the one hand, the limiting rods 28 limit the movement path of the cutter 23, ensure that the cutter 23 can only move towards the direction of the hot melt column 13, effectively avoid the cutter 23 from deviating or shaking during the movement process, so that the cutter 23 can accurately reach the cutting position according to the predetermined trajectory, lay a foundation for subsequent accurate cutting of the pipeline 11, on the other hand, the clamping of the gaskets 29 can ensure that the cutter 23 moves horizontally, ensure that the cutter 23 can pass through the cutter groove 22 provided in the heat insulation ring 21 and smoothly enter the inside of the heat insulation ring 21, and then cut the pipeline 11, which not only improves the cutting efficiency, but also guarantees the flatness and cutting quality of the cutting surface, reduces the cutting deviation and burr caused by unstable movement of the cutter 23.

[0045] The trigger mechanism 3 comprises a pressure sensor 33 fixedly connected to one end of the spring 31 away from the spring 31, and the pressure sensor 33 is electrically connected with the electric telescopic rod 24.

[0046] When the pipeline 11 is connected with the tee pipe 12, the pipeline 11 is inserted into the hot melt column 13, at this time, the pipeline 11 wraps the hot melt column 13, and the end of the pipeline 11 abuts against the pressure sensor 33 on the outer wall of the stop ring 32, since the pressure sensor 33 is electrically connected with the electric telescopic rod 24, the electric telescopic rod 24 is automatically triggered by the pressure signal to drive the cutter 23 to move, without the need for additional manual operation to start the cutting link, which not only conforms to the natural process of the pipeline 11 hot melt process, improves the continuity and convenience of the operation, but also ensures that the cutting action is timely and accurate after the pipeline 11 is correctly positioned, effectively improves the efficiency and accuracy of the connection operation of the pipeline 11 and the tee pipe 12.

[0047] The working principle and use process of the present application are as follows:

[0048] When the pipeline 11 is connected with the tee pipe 12, the pipeline 11 is inserted into the hot melt column 13, at this time, the pipeline 11 wraps the hot melt column 13, and the end of the pipeline 11 abuts against the pressure sensor 33 on the outer wall of the stop ring 32, since the pressure sensor 33 is electrically connected with the electric telescopic rod 24, the electric telescopic rod 24 is automatically triggered by the pressure signal to drive the cutter 23 to move, when the electric telescopic rod 24 is powered, the output end of the electric telescopic rod 24 drives the cutter 23 to move, and the cutter 23 can enter the inside of the heat insulation ring 21 through the cutter groove 22 when moving, and the cutter 23 cuts the end of the pipeline 11 in a ring shape;

[0049] The waste after cutting is located between the pipeline 11 and the stop ring 32, after the pipeline 11 is removed, the spring 31 resets to lift the stop ring 32, and the waste is ejected out of the heat insulation ring 21 by the inertia of the stop ring 32;

[0050] Similarly, when the electric telescopic rod 24 is retracted, the output end of the electric telescopic rod 24 pulls the cutter 23 back, the stop rod two 26 located on the outer wall of the cutter 23 drives the stop rod one 25 of the adjacent cutter 23 to move, thereby driving the adjacent cutter 23 to move;

[0051] When the cutter 23 moves, the cutter 23 is limited by the gaskets 29 at both ends, and when the cutter 23 slides, the limiting rod 28 is located inside the limiting groove 27 opened in the cutter 23, which on the one hand limits the movement path of the cutter 23 and ensures that the cutter 23 can only move towards the hot melt column 13;

[0052] On the other hand, the clamping of the gasket 29 can ensure the horizontal movement of the cutter 23 and ensure that the cutter 23 can pass through the cutter groove 22 opened in the heat insulation ring 21 and smoothly enter the inside of the heat insulation ring 21, thereby cutting the pipeline 11.

[0053] Embodiment two

[0054] Please refer to Figures 9-12 The application also provides a technical solution: a through groove 5 is opened on one side of the heat insulation ring 21, a connecting rod 51 is fixedly connected to the outer wall of the stop ring 32, the connecting rod 51 is located inside the through groove 5, and the connecting rod 51 is in sliding connection with the through groove 5;

[0055] The electromagnet one 52 is fixedly connected to one end of the connecting rod 51 close to the hot melt device 1, the hot melt device 1 is fixedly connected with an electromagnet two 53 on the outer wall, and the electromagnet one 52 and the electromagnet two 53 are in position correspondence.

[0056] The electromagnet one 52 and the electromagnet two 53 are respectively connected with the circuit of the electric telescopic rod 24.

[0057] When the pipeline 11 penetrates into the hot melt column 13, the pipeline 11 abuts against the stop ring 32 and pushes the stop ring 32, the connecting rod 51 located on the outer wall of the stop ring 32 slides inside the through groove 5 until the electromagnet one 52 fixedly connected to one end of the connecting rod 51 close to the hot melt device 1 contacts with the electromagnet two 53 fixedly connected to the outer wall of the hot melt device 1, at this time, the electric telescopic rod 24 is electrified, and this triggering mode is suitable for the situation that the end of the pipeline 11 is uneven, the force on the pressure sensor 33 is uneven, and the electric telescopic rod 24 receives the pressure signal with deviation. Regardless of the state of the end of the pipeline 11, as long as it penetrates into the hot melt column 13 and pushes the stop ring 32, the electromagnet can accurately contact and trigger, the electric telescopic rod 24 can be electrified in time to drive the cutter 23 to work, and the adaptability of the equipment to different conditions of the pipeline 11 and the stability and reliability of the cutting operation are greatly improved.

[0058] Embodiment three

[0059] Please refer to Figure 8The application also provides a technical solution: the trigger mechanism 3 comprises a temperature sensor 4 fixedly connected to one end of the spring 31 away from the blocking ring 32, and the temperature sensor 4 is electrically connected with the electric telescopic rod 24.

[0060] In the mode of using the temperature sensor 4, on the one hand, the safety of equipment operation is greatly improved, and the personal safety of the operator is ensured, because the movement of the blocking ring 32 caused by the accidental touch of the operator is avoided, and the temperature sensor 4 only responds to temperature changes and is not disturbed by accidental touch, on the other hand, after the hot melt column 13 is heated, the pipeline 11 is heated immediately, the temperature is conducted from the hot melt column 13 to the temperature sensor 4 through the pipeline 11, when the temperature sensor 4 sends the temperature signal to the electric telescopic rod 24, the pipeline 11 has been in a heated state, the material of the pipeline 11 becomes soft, and is more easily cut by the cutter 23, so that the cutting surface is flat and smooth, the cutting quality is improved, the accurate connection of the pipeline 11 and the tee pipe 12 is provided with strong guarantee, and the efficiency and reliability of the whole pipeline 11 connection process are improved.
