Description

Technical Field

[0001] The utility model relates to the technical field of power cables, in particular to a plugging device for pipelines with better sealing performance. Background Art

[0002] During the laying and installation process of power cables, the cables are installed in power pipelines during installation, and then the ports need to be plugged, usually using a pipeline plugging device for plugging. The pipeline plugging device is a plugging device, generally made of rubber. After being stressed (or by air pressure), the rubber expands inwards and outwards, filling the cross-section between the cable pipeline and the cable, thereby fixing the cable and achieving the sealing of the pipeline.

[0003] In the existing pipeline plugging devices, multiple rubber pads are used in cooperation with bolts and nuts. After sleeving two groups of rubber pad assemblies onto the cable, the rubber pad assemblies are inserted into the pipeline. By rotating the bolts, the connecting plates at both ends of the rubber pad approach each other, thereby compressing the rubber pad and making the rubber pad expand, so as to achieve the fixation of the cable and the fixation and installation in the pipeline. In the existing multi-layer plugging devices, although the rubber pad can be stably arranged in the pipeline after being extruded and expanded, the sealing effect cannot be guaranteed, and the situation of poor sealing effect may occur, which will affect the plugging effect. Moreover, when the plugging device is sleeved onto the cable, positioning connection cannot be carried out. After the plugging device is inserted into the pipeline, misalignment may occur, which will also affect the plugging effect, and the use effect is average. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a plugging device for pipelines with better sealing performance, which solves the problem that in the prior art, although the rubber pad can be stably arranged in the pipeline after being extruded and expanded, the sealing effect cannot be guaranteed, and the situation of poor sealing effect may occur, which will affect the plugging effect.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A plugging device for pipelines with better sealing performance includes a pipeline body and a top cover arranged at one end of the pipeline body. A conical column is connected to the center of one side of the top cover;

[0007] The diameter of the top cover is larger than the diameter of the pipeline body. One end diameter of the conical column is smaller than the diameter of the pipeline body, and the other end diameter is larger than the diameter of the pipeline body and smaller than the diameter of the top cover;

[0008] Side plates are arranged on both sides of the pipeline body. Each side plate is connected to a positioning plate through an inclined sloping plate. Every two adjacent positioning plates are detachably connected;

[0009] One side of the inclined plate is connected with a fixing plate. At the center of the bottom of the fixing plate, there is a fixing screw rod with one end passing through the fixing plate through a screw sleeve. One end of the fixing screw rod is connected with the bottom of the top cover.

[0010] Preferably, the conical column is made of rubber material, and several sealing rings are connected to the outer circle of the conical column.

[0011] Preferably, several fixing holes are opened at the bottom of the top cover. One end of the fixing screw rod is threadedly connected with the inside of the fixing hole, and a handle is connected to the bottom end of the fixing screw rod.

[0012] Preferably, a rubber pad is connected to the center of the side of the inclined plate away from the fixing plate, and several anti-slip grooves are opened on one side of the rubber pad.

[0013] Preferably, several connecting screw rods are used to connect between two adjacent positioning plates, and both of the inclined plates are made of metal material.

[0014] Preferably, the length of the fixing screw rod is greater than the lengths of the side plate and the conical column.

[0015] The utility model has at least the following beneficial effects:

[0016] When installing a power cable, first lay the cable in the pipe body. Then, place the top cover at one end of the pipe body. At this time, the diameter of the top cover is greater than that of the pipe body, and it can cover the pipe port. The conical column connected to the center of one side of the top cover plays a role of guiding and positioning. The diameter of one end of it is smaller than that of the pipe body, which is convenient for inserting into the pipe; the diameter of the other end is greater than that of the pipe body and smaller than that of the top cover, ensuring a firm connection between the top cover and the pipe body. Subsequently, set the side plates on both sides of the pipe body. Both sides of each side plate are connected to the positioning plates through inclined plates arranged obliquely. The detachable connection between every two adjacent positioning plates is designed in this way, which is convenient for installation and ensures the structural stability. One side of the inclined plate is also connected with a fixing plate. At the center of the bottom of the fixing plate, there is a fixing screw rod with one end passing through the fixing plate through a screw sleeve. Finally, connect one end of the fixing screw rod with the bottom of the top cover, so as to firmly install the whole plugging device at the port of the pipe body.

[0017] The sealing effect is improved: Compared with the traditional method of using multiple rubber pads in cooperation with bolts and nuts for plugging, through the design of structures such as the top cover, conical column, side plates, and positioning plates in this scheme, a tighter plugging of the pipe port is realized, effectively avoiding the situation of poor sealing effect, and thus improving the plugging effect.

[0018] Enhanced stability: The side plates are connected to the positioning plates through inclined plates, and every two adjacent positioning plates are detachably connected, which not only facilitates installation and disassembly, but also greatly enhances the stability of the plugging device, ensuring that there is no loosening or falling off during use.

[0019] Achieved positioning connection: When the plugging device is sleeved onto the cable, positioning connection can be carried out through the positioning plates, ensuring that the plugging device can be accurately aligned after being inserted into the pipe interior, thus avoiding the problem of affecting the plugging effect due to misalignment and improving the use effect.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following will further describe the present invention in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Refer to Figures 1-4 , a plugging device for pipes with better sealing performance, including a pipe body 1 and a top cover 2 provided at one end of the pipe body 1, and a conical column 9 is connected to the center of one side of the top cover 2;

[0028] The diameter of the top cover 2 is larger than that of the pipe body 1, the diameter of one end of the conical column 9 is smaller than that of the pipe body 1, and the diameter of the other end is larger than that of the pipe body 1 and smaller than that of the top cover 2;

[0029] Both sides of the pipe body 1 are provided with side plates 3. Both sides of each side plate 3 are connected with positioning plates 5 through inclined plates 6 arranged obliquely, and every two adjacent positioning plates 5 are detachably connected;

[0030] One side of the inclined plate 6 is connected with a fixing plate 7. At the center of the bottom of the fixing plate 7, there is a fixing screw 11 whose one end passes through the fixing plate 7 through a screw sleeve, and one end of the fixing screw 11 is connected with the bottom of the top cover 2.

[0031] This solution has the following working process:

[0032] When installing the power cable, first lay the cable in the pipe body 1. Then, place the top cover 2 at one end of the pipe body 1. At this time, the diameter of the top cover 2 is larger than that of the pipe body 1, and it can cover the pipe port. The conical column 9 connected to the center of one side of the top cover 2 plays a role of guiding and positioning. The diameter of one end of it is smaller than that of the pipe body 1, which is convenient for inserting into the pipe; the diameter of the other end is larger than that of the pipe body 1 and smaller than that of the top cover 2, ensuring a firm connection between the top cover 2 and the pipe body 1. Subsequently, set the side plates 3 on both sides of the pipe body 1. Both sides of each side plate 3 are connected with the positioning plates 5 through the inclined plates 6 arranged obliquely. Every two adjacent positioning plates 5 are detachably connected. Such a design is not only convenient for installation but also ensures the structural stability. One side of the inclined plate 6 is also connected with a fixing plate 7. At the center of the bottom of the fixing plate 7, there is a fixing screw 11 whose one end passes through the fixing plate 7 through a screw sleeve. Finally, connect one end of the fixing screw 11 with the bottom of the top cover 2, thereby firmly installing the entire sealing device at the port of the pipe body 1.

[0033] According to the above working process, it can be known that:

[0034] The sealing effect is improved: Compared with the traditional method of using multiple rubber gaskets in combination with bolts and nuts for plugging, this solution realizes a tighter plugging of the pipe port through the design of structures such as the top cover 2, the conical column 9, the side plates 3, and the positioning plates 5, effectively avoiding the situation of poor sealing effect, and thus improving the plugging effect.

[0035] The stability is enhanced: The side plates 3 are connected with the positioning plates 5 through the inclined plates 6, and every two adjacent positioning plates 5 are detachably connected, which is not only convenient for installation and disassembly but also greatly enhances the stability of the sealing device, ensuring that it will not loosen or fall off during use.

[0036] The positioning connection is realized: When the sealing device is sleeved on the cable, the positioning connection can be carried out through the positioning plates 5, ensuring that the sealing device can be accurately aligned after being inserted into the pipe, thus avoiding the problem of affecting the plugging effect due to misalignment and improving the use effect.

[0037] Furthermore, the conical column 9 is made of rubber material, and a number of sealing rings 12 are connected to the outer ring of the conical column 9.

[0038] Furthermore, a number of fixing holes 10 are formed at the bottom of the top cover 2. One end of the fixing screw 11 is threadedly connected to the inside of the fixing hole 10, and a handle is connected to the bottom end of the fixing screw 11.

[0039] Furthermore, a rubber pad 4 is connected to the center of the side of the inclined plate 6 away from the fixing plate 7, and a number of anti-slip grooves are formed on one side of the rubber pad 4.

[0040] Furthermore, a number of connecting screws 8 are used to connect between two adjacent positioning plates 5, and both of the two inclined plates 6 are made of metal material.

[0041] Furthermore, the length of the fixing screw 11 is greater than the lengths of the side plate 3 and the conical column 9.

[0042] When installing the power cable, first lay the cable in the pipeline body 1. Then, place the top cover 2 at one end of the pipeline body 1. At this time, the diameter of the top cover 2 is greater than that of the pipeline body 1, and it can cover the pipeline port. The conical column 9 connected to the center of one side of the top cover 2 plays a role of guiding and positioning. One end of it has a diameter smaller than that of the pipeline body 1, which is convenient for inserting into the pipeline; the other end has a diameter greater than that of the pipeline body 1 and smaller than that of the top cover 2, ensuring a stable connection between the top cover 2 and the pipeline body 1. Furthermore, the conical column 9 is made of rubber material, and a number of sealing rings 12 are connected to its outer ring, which enhances the sealing performance between the conical column 9 and the pipeline body 1 and effectively prevents the leakage of gas or liquid.

[0043] Subsequently, arrange the side plates 3 on both sides of the pipeline body 1. Both sides of each side plate 3 are connected to the positioning plates 5 through the inclined plates 6 arranged obliquely. A rubber pad 4 is connected to the center of the side of the inclined plate 6 away from the fixing plate 7, and a number of anti-slip grooves are also formed on one side of the rubber pad 4, which not only increases the friction force but also prevents the cable from being damaged by the plugging device during the installation process. A number of connecting screws 8 are used to detachably connect between every two adjacent positioning plates 5, which is convenient for installation and ensures the structural stability. At the same time, both of the two inclined plates 6 are made of metal material, enhancing the durability and impact resistance of the plugging device.

[0044] Next, one side of the inclined plate 6 is also connected to a fixing plate 7. At the center of the bottom of the fixing plate 7, there is a fixing screw 11 with one end passing through the fixing plate 7 through a screw sleeve. A number of fixing holes 10 are also opened at the bottom of the top cover 2. One end of the fixing screw 11 is threadedly connected to the inside of the fixing hole 10, and a handle is connected to the bottom end of the fixing screw 11, which not only facilitates the rotation operation of the fixing screw 11 but also ensures a firm connection between the top cover 2 and the fixing plate 7. The length of the fixing screw 11 is greater than the lengths of the side plate 3 and the conical column 9, which ensures that the fixing screw 11 can fully penetrate each layer of structure and firmly install the entire plugging device at the port of the pipeline body 1.

[0045] The beneficial effects of this technical solution are mainly reflected in the following aspects:

[0046] Improved sealing effect: Compared with the traditional method of using multiple rubber gaskets in combination with bolts and nuts for plugging, this solution, through the design of structures such as the top cover 2, the conical column 9, the side plate 3, and the positioning plate 5, especially with the conical column 9 made of rubber material and connected with a sealing ring 12, realizes a tighter plugging of the pipeline port, effectively avoiding the situation of poor sealing effect, and thus improving the plugging effect.

[0047] Enhanced stability: The side plate 3 is connected to the positioning plate 5 through the inclined plate 6, and every two adjacent positioning plates 5 are detachably connected through the connecting screw 8, which not only facilitates installation and disassembly but also greatly enhances the stability of the plugging device. At the same time, the inclined plate 6 is made of metal material, further improving the durability and impact resistance of the plugging device, ensuring that it will not loosen or fall off during use.

[0048] Realized positioning connection: When the plugging device is sleeved on the cable, positioning connection can be carried out through the positioning plate 5 to ensure that the plugging device can be accurately aligned after being inserted into the pipeline. The design of the rubber gasket 4 and the anti-slip groove not only increases the friction but also prevents damage to the cable, thus avoiding the problem of affecting the plugging effect due to misalignment and improving the use effect.

[0049] Facilitated operation and maintenance: A handle is connected to the bottom end of the fixing screw 11, facilitating the rotation operation; the length design of the fixing screw 11 ensures that it can fully penetrate each layer of structure to achieve a firm connection; at the same time, the detachable connection method also facilitates the later maintenance and replacement of the plugging device.
