Description

Technical Field

[0001] This utility model belongs to the field of high-pressure pipeline pump technology, and in particular relates to a quick coupling for high-pressure pipeline pumps. Background Technology

[0002] High-pressure pipeline pumps are high-efficiency centrifugal pumps that combine the advantages of high pressure, pipeline installation, compact structure, and convenient maintenance. They are important equipment for solving the high-pressure liquid transportation needs in industrial processes, building water supply, fire protection systems, and other fields.

[0003] Patent CN212429318U discloses a high coaxiality connection structure for a pipeline pump, including a pump body. A first connector is fixedly connected to both the output and input ends of the pump body. An arc-shaped limiting block is fixedly connected to the end of each first connector. A limiting mechanism is provided on the side of each first connector away from the limiting block. A second connector is slidably connected inside each limiting block. An installation mechanism is provided inside each second connector and on the side of the limiting mechanism. The beneficial effects of this invention are: the invention has a compact structure and strong practicality. By setting mutually cooperating first and second connectors, one end of the pipeline pump and connecting pipe can be quickly limited. Simultaneously, with the limiting mechanism and installation mechanism, the pipeline pump and connecting pipe can be quickly installed and disassembled, thereby greatly increasing the installation and disassembly speed of the pipeline pump and making the installation and disassembly of the pipeline pump more convenient and faster.

[0004] In existing technologies, the pipeline pump can be quickly disassembled by setting a limiting mechanism and an installation mechanism, but the following problems still exist in its overall use: First, when installing the pipeline pump, the existing technology usually requires rotating or tensioning the connecting parts for installation, without limiting the pipeline. This causes the pipeline to rotate axially under high pressure, which can seriously damage the shaft seal and connecting parts, affect the service life of the pipeline, and even endanger public safety. Second, after prolonged use under high pressure, the connection joints of the existing pipeline pump may loosen or even detach from the pipeline. The existing device cannot detect the connection between the pipeline and the joint, and cannot perform timely maintenance. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a quick coupling for high-pressure pipeline pumps. By incorporating mechanisms such as a fixing ring and toothed blocks, it can limit the movement of the pipeline, solving the problem that existing quick couplings do not limit the movement of the pipeline, causing axial rotation of the pipeline under high-pressure conditions. Axial rotation can severely damage the shaft seal and connecting parts, affecting the service life of the pipeline and even endangering public safety. By incorporating mechanisms such as a pressure sensor and a detection baffle, it can detect the position of the detection baffle, solving the problem that existing devices cannot detect the connection between the pipeline and the coupling, and cannot perform timely maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick connector for a high-pressure pipeline pump, comprising a pipeline pump, wherein both ends of the pipeline pump are provided with connecting ends, both outer surfaces of the two connecting ends are provided with fixing rings, both fixing rings are provided with nested pipes inside, both nested pipes are slidably provided with high-pressure pipes on their outer surfaces, both high-pressure pipes are provided with positioning rings on their outer surfaces, and both positioning rings are provided with multiple toothed blocks on the side adjacent to the fixing rings, the multiple toothed blocks being able to engage with each other.

[0007] Preferably, the outer surface of the high-pressure pipeline is provided with a plurality of movable grooves, and a reinforcing rod is rotatably provided inside each of the plurality of movable grooves. A rotating shaft is provided inside each of the plurality of reinforcing rods, and the plurality of rotating shafts are respectively fixedly connected to the inner wall of the movable groove.

[0008] Preferably, each of the multiple reinforcing rods has a connector at one top end, each of the multiple connectors has a slot on its outer surface, each of the multiple slots has a connecting rod slidably disposed inside it, each of the multiple connecting rods has a connecting handle at both ends, each pair of connecting handles forms a group, each group of connecting handles has a handle rotatably disposed at one end, each of the multiple handles has a rotating mounting component rotatably disposed at one end, and each of the multiple rotating mounting components is fixedly connected to the fixing ring.

[0009] Preferably, each of the reinforcing rods has a protrusion at one bottom end, and a reinforcing groove is provided below the reinforcing rods on the outer surface of the nested pipe, the reinforcing groove slidingly abutting against the reinforcing rods.

[0010] Preferably, the interior of the plurality of movable slots is provided with straight groove edges, which can limit the connection of the connector, and the plurality of movable slots can accommodate the reinforcing rod.

[0011] Preferably, one end of each of the plurality of handles is provided with a detection baffle, and one side of each of the plurality of detection baffles is provided with a mounting shell on the outer surface of the high-pressure pipeline. A pressure sensor is slidably disposed inside each of the plurality of mounting shells, and the detection end of the plurality of pressure sensors slides against the detection baffle.

[0012] Preferably, each of the multiple mounting housings has a sliding rod inside, and each of the multiple sliding rods has a slider slidably disposed on its outer surface. Each of the multiple sliders is fixedly connected to a pressure sensor, and each of the multiple sliders has a movable rod on its side near the connecting handle. One end of each of the multiple movable rods slides against the connecting handle.

[0013] Preferably, a sealing strip is provided between the fixing ring and the positioning ring.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) By setting a fixing ring, a positioning ring, a toothed block and a connecting piece, the present invention can limit the pipe and prevent the pipe from axially twisting under high pressure, thereby improving the stability of the pipe connection. By setting a connecting piece and a connecting handle and a handle, the pipe can be quickly connected to the pipe pump without rotating the entire pipe or pump body, making the installation more convenient and efficient. With the reinforcement rod and reinforcement groove, the nested pipe can be continuously pulled into the high pressure pipe during the fixing process, and the position of the nested pipe can be fixed, further strengthening the connection strength between the pipe pump and the high pressure pipe. (2) This utility model can detect the position of the detection baffle by setting a pressure sensor, a detection baffle, a movable groove and a reinforcing rod. When the position of the detection baffle changes, pressure will be applied to the detection end of the pressure sensor. The pressure sensor collects the detection information and sends an alarm signal so that the pipeline can be repaired and inspected in time. At the same time, the sealing strip can increase the sealing degree between the fixed ring and the positioning ring. Attached Figure Description

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A quick connector for a high-pressure pipeline pump includes a pipeline pump 10. Both ends of the pipeline pump 10 are provided with connecting ends 11. A retaining ring 18 is provided on the outer surface of each connecting end 11. The two retaining rings 18 are welded to the connecting ends 11. Nested pipes 22 are provided on the inner walls of the connecting ends 11 within the two retaining rings 18. The two nested pipes 22 extend outward from the connecting ends 11. High-pressure pipes 12 are slidably mounted on the outer surfaces of the two nested pipes 22. Positioning rings 19 are provided on the outer surfaces of the two high-pressure pipes 12. Multiple toothed blocks 2 are provided on the side of the positioning rings 19 adjacent to the retaining rings 18. 0. Multiple toothed blocks 20 can interlock with each other. By setting the toothed blocks 20, the high-pressure pipeline 12 and the connecting end 11 can be prevented from twisting under high-pressure environment, thereby improving the stability of the connection and extending the service life of the high-pressure pipeline 12. A sealing strip 21 is provided between the fixing ring 18 and the positioning ring 19. By setting the sealing strip 21, the sealing performance between the fixing ring 18 and the positioning ring 19 can be enhanced. At the same time, the sealing strip 21 is located outside the nested pipeline 22, which can prevent the sealing strip 21 from directly contacting the high-pressure fluid, reduce the impact of the high-pressure fluid on the sealing strip, and extend the service life of the sealing strip 21.

[0018] Further reference Figure 2 , Figure 3 , Figure 4 and Figure 5The outer surface of the high-pressure pipe 12 is provided with multiple movable grooves 26. Each movable groove 26 has a reinforcing rod 24 rotatably mounted inside it. Each reinforcing rod 24 has a rotating shaft 25 inside it, and each rotating shaft 25 is fixedly connected to the inner wall of the movable groove 26. Each reinforcing rod 24 has a connector 13 at one top end. Each connector 13 has a slot 32 on its outer surface, and a connecting rod is slidably mounted inside each slot 32. Each connecting rod has a connecting handle 14 at both ends, with two connecting handles 14 forming a group. Each group of connecting handles 14 has a handle 15 rotatably mounted at one end, and a rotating mounting part 16 rotatably mounted at one end of each handle 15. Each rotating mounting part 16 is fixedly connected to a fixing ring 18. When installing the high-pressure pipe 12, the positions of the connector 13 and the connecting handle 14 on the outer surface of the high-pressure pipe 12 are aligned. By pushing the high-pressure pipe 12, multiple toothed blocks 20 on the outer surface of the positioning ring 19 are engaged with the fixing ring 18. When fixing the high-pressure pipe 12, first... Rotate the connecting handle 14 to slide the connecting rod at one end of the connecting handle 14 into the slot 32. Then, simply rotate the handle 15 so that the handle 15 rotates along the rotating mounting part 16 and pulls one end of the connecting handle 14, pulling the connecting handle 14 towards the connecting end 11. At the same time, the connecting rod pulls the connecting part 13 towards the connecting end 11. To prevent the connecting part 13 from rotating and failing to pull the high-pressure pipeline 12, straight groove edges 33 are provided inside the multiple movable grooves 26. The straight groove edges 33 can limit the connecting part 13, so that the connecting part 13 can rotate inside the movable groove 26. At the same time, the straight groove edges 33 can limit the rotation angle of the connecting part 13. When the connecting part 13 rotates towards the connecting end 11, it can only be in a vertical state at most. When the connecting part 13 is in a vertical state, as the connecting handle 14 continues to pull the connecting part 13, the connecting part 13 pulls the high-pressure pipeline 12 closer to the connecting end 11. And as the handle 15 rotates, the connecting handle 14 fixes the connecting part 13.

[0019] When it is necessary to release the fixation of the high-pressure pipe 12, simply rotate the handle 15 in the opposite direction, causing the handle 15 to move the connecting handle 14. During the movement, the connecting handle 14 moves the connecting rod, causing the connecting rod to disengage from the inside of the slot 32. Then, rotate the reinforcing rod 24. Multiple movable slots 26 can accommodate the reinforcing rod 24. Subsequently, the high-pressure pipe 12 can be removed from the inside of the connecting end 11.

[0020] Further reference Figure 2 , Figure 3 , Figure 4 and Figure 5Each of the reinforcing rods 24 has a protrusion at one bottom end. A reinforcing groove 23 is provided below the reinforcing rods 24 on the outer surface of the nested pipe 22. The reinforcing groove 23 slides against the reinforcing rods 24. When connecting the high-pressure pipe 12, the reinforcing rods 24 need to be rotated to house them inside the movable groove 26. Then, when the nested pipe 22 enters the high-pressure pipe 12, rotating the reinforcing rods 24 causes the protrusions of the reinforcing rods 24 to enter the reinforcing groove 23. When fixing the high-pressure pipe 12, the connector 13 rotates according to the pivot 25, causing the protrusions of the reinforcing rods 24 to rotate towards the high-pressure pipe 12 and push the groove wall of the reinforcing groove 23 towards the high-pressure pipe 12. This, in turn, causes the high-pressure pipe 12 to move through the nested pipe 22, further strengthening the connection between the connecting end 11 and the high-pressure pipe 12.

[0021] Further reference Figure 2 , Figure 3 and Figure 4 Each of the multiple handles 15 has a detection baffle 17 at one end. Each of the multiple detection baffles 17 has a mounting shell 27 on one side of its outer surface relative to the high-pressure pipe 12. Each of the multiple mounting shells 27 has a pressure sensor 30 slidably mounted inside it. The detection end of each pressure sensor 30 slidably abuts against the detection baffle 17. Each of the multiple mounting shells 27 has a sliding rod 28 inside it. Each of the multiple sliding rods 28 has a slider 29 slidably mounted on its outer surface. Each slider 29 is fixedly connected to a pressure sensor 30. Each slider 29 has a movable rod 31 on its side near the connecting handle 14. One end of each movable rod 31 slidably abuts against the connecting handle 14. After the high-pressure pipe 12 is fixed, the movable rod 31 pulls the slider 29, causing the slider 29 to move towards the high-pressure pipe 12. Simultaneously, the slider 29 moves the pressure sensor 30 at its bottom, transmitting the pressure. The detection end of the pressure sensor 30 abuts against the top end face of the detection baffle 17 to detect the detection baffle 17. When the high-pressure pipeline 12 is displaced, the high-pressure pipeline 12 drives the connecting handle 14 to move through the connector 13. The connecting handle 14 drives the handle 15 to rotate, and the handle 15 drives the detection baffle 17 to move, thereby applying pressure to the pressure sensor 30. After detecting the pressure information, the pressure sensor 30 sends a signal to facilitate timely maintenance. At the same time, after the movable rod 31 is pulled out, it abuts against the upper end face of the connecting handle 14 to apply a certain pressure to the connecting handle 14, preventing the connecting handle 14 from rotating upward and causing the connecting rod to detach from the connector 13, thereby further improving the stability of the connection. At the same time, the mounting shell 27 can protect the pressure sensor 30 from rainwater, preventing rainwater from affecting the detection effect of the pressure sensor 30 and improving the pressure sensor 30's resistance to wind and sand.

The control of the driving component by the detection component and the related detection methods and specific circuit relationships of each detection component can all adopt conventional electrical control technology. As long as the corresponding motion relationship can be completed and its beneficial effect can be achieved, it can be implemented. The pipeline pump 10 and pressure sensor 30 in this utility model's quick coupling for a high-pressure pipeline pump are all purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
