Description

Technical Field

[0001] The utility model belongs to the technical field of wire threading and sealing, and particularly relates to a combined device for anti-seepage, plugging and wire threading sealing. Background Technique

[0002] Various sensors are installed in various mechanical equipment such as steam turbines and pumps, and all need to be connected to instruments outside the machine through wires to transmit various parameters. Since the internal environment of the machine often contains oils in various states, when the wires are led out, the oils inside the machine will leak from the wire outlet holes to the outside of the machine, which not only pollutes the external environment of the machine, but also the more serious harm is that it will cause major safety hazards such as fires. In order to prevent the oils inside the machine from leaking from the wire outlet holes to the outside of the machine, it is often necessary to carry out anti-seepage and plugging treatment on the connection points;

[0003] At present, the existing sealing methods mainly connect to the equipment through ordinary screw joints and pour sealing glue into them, or adopt the method of sealing with a tapered hole, a rubber plug and an O-ring;

[0004] Among the above treatment methods, the method of pouring sealing glue is easy to leak, affects the appearance, and requires a lot of manpower and time for glue removal during each subsequent maintenance, wasting resources and having relatively large safety hazards at the same time; secondly, the method of using a tapered hole, a rubber plug and an O-ring for sealing has a limited number of single wire outlet hole seals on the equipment used, and power plants often need to lead out multiple wires from each hole on site, and the external wire protection sleeves of the machine do not match the device, and it is often a subsequent problem to install the protection sleeves, which is time-consuming and laborious. The above two methods have poor versatility, are cumbersome and complex to disassemble and assemble, and have relatively high technical requirements and operating requirements for installation, which brings a lot of inconvenience to the on-site construction of power plants;

[0005] To solve the above problems, a combined device for anti-seepage, plugging and wire threading sealing is proposed in this application. Content of the Utility Model

[0006] The purpose of the utility model is to provide a combined device for anti-seepage, plugging and wire threading sealing, which solves the problems put forward in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model is a combined device for anti-seepage, plugging and wire threading sealing, including: a base and a metal protection hose; a positioning plate is arranged at the upper end of the base, and a locking plate is installed at the upper end of the positioning plate through bolts to limit multiple metal protection hoses therein. An anti-leakage plate is arranged inside the locking plate to dock with the metal protection hose to meet the working requirements of multi-point wire threading; a stud is arranged inside the anti-leakage plate, and a rubber plug is installed through a threaded pipe at its upper end to fill the internal cavity when the metal protection hose is installed, so as to achieve the overall anti-seepage and plugging effect.

[0009] Further, a screw sleeve is spirally installed on the outer side of the threaded pipe and is docked with a nut on the outer side of the metal protective hose adjacent to the lower end position. The cooperation between the screw sleeve and the nut is also used to fix the rubber plug to prevent loosening.

[0010] Further, a positioning hole is formed inside the leak-proof plate for matching multiple strands of wires to connect to the metal protective hose.

[0011] Further, a sealing cavity for receiving the rubber plug is formed between the upper end surface of the screw sleeve and the threaded pipe, and is also used to pre-fix the rubber plug for subsequent docking operations.

[0012] Further, a conical rubber pad is provided at the lower end of the rubber plug, and its inner side is warped inward. When the metal protective hose enters, it is squeezed by the metal protective hose to form an inward contraction, so as to tightly fill the gap to prevent loosening.

[0013] Further, a transfer plate is provided at the lower end of the leak-proof plate and is docked between the positioning plate and the locking plate.

[0014] Further, the separation structure of the transfer plate, in cooperation with the positioning plate and the locking plate, is used to match different leak-proof plates according to the on-site construction requirements.

[0015] Further, a protruding external threaded screw pipe is provided at the lower end of the column head and is spirally installed inside the positioning hole.

[0016] The utility model has the following beneficial effects:

[0017] Through the cooperation of the column head and the leak-proof plate, the utility model can pass multiple strands of metal protective hoses through the inside of the equipment. Furthermore, when installing the metal protective hose, the warped part inside the conical rubber pad can fill the gap when the metal protective hose enters. Furthermore, when the metal protective hose continues to enter, the conical rubber pad is tightly squeezed and fixed. At this time, it can effectively prevent substances such as oil from entering the gap, achieving the effect of overall anti-seepage and leak prevention. The structure is simple, convenient for disassembly, installation and operation, and the overall appearance is neat and beautiful after installation.

[0018] Of course, when implementing any product of the utility model, it is not necessarily required to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

[0028] Please refer to Figures 1-4 As shown, the present utility model is an anti-seepage and leak-stopping wire threading and sealing combination device, including: a base 1 and a metal protection hose 2; a positioning disk 3 is provided at the upper end of the base 1, and a locking disk 4 is installed at the upper end of the positioning disk 3 through bolts for limiting multiple metal protection hoses 2 therein. A leak-proof tray 5 is provided inside the locking disk 4 to be butted against the metal protection hose 2 to meet the working requirements of multi-point wire threading. A transfer disk 14 is provided at the lower end of the leak-proof tray 5 to be butted between the positioning disk 3 and the locking disk 4. The separation structure of the transfer disk 14, in cooperation with the positioning disk 3 and the locking disk 4, is used to match different leak-proof trays 5 according to the on-site construction requirements;

[0029] The anti-leakage disk 5 is provided with a column head 6 inside, and a rubber plug 12 is installed through the threaded tube 7 at the upper end thereof, which is used to fill the internal cavity when the metal protective hose 2 is installed to achieve the overall anti-seepage and anti-leakage effect;

[0030] The present embodiment provides a universal threading and sealing combination mechanism, which utilizes the conical structure of the rubber plug 12 in conjunction with the column head 6 to tightly fill the gap cavity when the metal protective hose 6 is installed to form a combination, so as to achieve the overall anti-seepage and leakage effect. The structure is simple and convenient for assembly and disassembly. After the installation is completed, the overall structure is neat and beautiful, which solves the problems of poor sealing, difficult disassembly and assembly, easy damage to cables, poor versatility, and dirty and messy site in the industry.

[0031] Among them, a screw sleeve 8 is spirally installed on the outer side of the threaded tube 7, which is connected to a nut 9 on the outer side of the metal protective hose 2 near the lower end. The cooperation between the screw sleeve 8 and the nut 9 is also used to fix the rubber plug 12 to prevent loosening. The upper end of the screw sleeve 8 is a protruding external threaded branch pipe mechanism. By utilizing the mutual cooperation between its upper end face and the inner upper end face of the nut 9, the rubber plug 12 can be tightly fixed inside, forming a seal while also being used to protect the two spiral mechanisms to replace the gasket.

[0032] Among them, the leak-proof disk 5 is provided with a positioning hole 10 inside for matching the multi-strand wire connection metal protective hose 2, so that the whole equipment can adapt to the working environment of threading multiple cables at the same time, which is convenient for on-site construction of power plants.

[0033] A sealed cavity 11 for receiving the rubber plug 12 is formed between the threaded sleeve 8 and the upper end surface of the threaded tube 7. At this time, the rubber plug 12 can be directly inserted into the interior to achieve a pre-fixing effect, which is convenient for subsequent docking operations.

[0034] The lower end of the rubber plug 12 is provided with a conical rubber pad 13, the inner side of which is inwardly tilted, and when the metal protective hose 2 enters, it is squeezed and shrunk, restoring the longitudinal straightness to tightly fill the gap and prevent it from loosening.

[0035] The lower end of the column head 6 is provided with a protruding external threaded screw tube, which is screwed on the inner side of the positioning hole 10 .

[0036] It can be understood that the utility model utilizes the perfect combination of the circular sealing cavity 11 and the conical rubber pad 13, and cooperates with the gap filling function during extrusion and shrinkage to achieve a good overall anti-seepage and leakage-proof effect, and the structure is simple and easy to operate, so that the equipment has strong versatility, and the overall appearance is neat and beautiful after installation. It effectively solves the problems of lax technical sealing in the industry, difficult disassembly and assembly, easy damage to cables, poor versatility, and dirty and messy site.

[0037] A specific application of the operation process of this embodiment is as follows: When in use, first, the leak-proof plate 5 is fixed inside by using bolts through the cooperation of the locking plate 4 and the positioning plate 3 to install the metal protection hose 2. Then, when the metal protection hose 2 enters, it first abuts against the upturned parts on the inner sides of the rubber plug 12 and the conical rubber pad 13. At this time, the nut 9 squeezes the rubber plug 12 to fix it inside the sealing cavity 11 for positioning. Then, with the continuous entry of the metal protection hose 2, the inner side of the lower end of the conical rubber pad 13 is further squeezed, so that it is tightly squeezed and fixed by the metal protection hose 2 to fill the gap and achieve the overall anti-seepage and leak-proof effect. The structure is simple, convenient for installation and disassembly, and at the same time, the appearance is neat and beautiful, meeting the working requirements of multi-strand wire threading mechanisms.
