Examples

Referring to fig. 4, at present, the plugging of the penetration site between the pipe orifice of the protection pipe 1 and the cable 2 is directly performed by using plugging mud 3, and the plugging mud 3 is easy to separate from the plugging site under the condition of external force or temperature change, so that the plugging is invalid. For this reason, the present embodiment provides a plugging cover 4 capable of supporting the plugging mud 3, please refer to fig. 5, which can fully support the plugging mud 3, so as to achieve a stable and tight plugging effect in a long-term use process.

Referring to fig. 1-3, the plugging cover 4 for a cable protecting tube port provided in this embodiment includes a cover 41 and a secondary plugging plate 44, wherein a first insertion opening 43 for clamping the cable 2 is formed on one side of the cover 41, that is, the first insertion opening 43 is capable of allowing the cable 2 to be clamped, so that the cover 41 and the cable 2 are clamped with each other, and a placing and supporting foundation is provided for the plugging mud 3. One side of the cover 41 is formed with a connecting edge 42 (for example, detachable connection: clamping connection, screw connection, riveting connection or buckling connection) for connecting the port of the protection tube 1, and the other side forms a receiving platform for containing the plugging mud 3, so that stable support can be formed for the plugging mud 3.

The secondary plugging plate 44 is fixed between the cover 41 and the connecting edge 42, i.e. the secondary plugging plate 44 is located at the inner side, especially the inner side taking the cover 41 as external protection, and is closer to the port of the protection tube 1. A second embedding opening 45 for clamping the cable 2 is formed in one side of the secondary plugging plate 44, namely, the second embedding opening 45 can allow the cable 2 to be clamped in, so that the secondary plugging plate 44 and the cable 2 are clamped with each other. The second embedded inlet 45 is mutually communicated with the first embedded inlet 43, so that the cable 2 can be synchronously clamped in one time between the second embedded inlet 45 and the first embedded inlet 43, and the effect of simultaneously clamping the cover 41 and the secondary plugging plate 44 is achieved.

In addition, the reinforcing platform for containing the plugging mud 3 is formed on one side, close to the cover 41, of the secondary plugging plate 44, so that the cable 2 can be plugged secondarily, the plugging is an inner space plugging, the effect of external force is not easy to occur, and the plugging stability is strong. The receiving platform extends or coats towards the first embedding port 43, and the reinforcing platform extends or coats towards the second embedding port 45, so that the contained plugging mud 3 can form a tight and sufficient coating effect around the circumference of the cable 2, and the purpose of long-term stable plugging is achieved.

When considering the position of cable 2 and protection tube 1 inner chamber interact, cable 2 appears being close to or lean on in the circumstances of protection tube 1 inner chamber border easily to form long-term stable connection condition, first embedded entry 43 eccentric arrangement is in lid 41, second embedded entry 45 eccentric arrangement is in secondary shutoff board 44, thereby comes to adapt to the circumstances that cable 2 is eccentric in protection tube 1 inner chamber, reduces cable 2 to the (resonance) effort of shutoff mud 3, realizes more stable shutoff effect.

On the basis of the above scheme, the first embedding opening 43 and the second embedding opening 45 are at least divided into a cable clamping area 431 and a cable embedding area 432 which are mutually communicated, that is, the corresponding embedding opening is formed by the clamping area 431 and the cable embedding area 432. The cable clamping area 431 is used for limiting the position of the cable 2 and is located at a position, close to the center, of the corresponding cover plate 41 or secondary plugging plate 44, and the cable embedding area 432 is used for enabling the cable to enter or exit and is located at a position, close to the edge, of the corresponding cover plate 41 or secondary plugging plate 44, of the cable embedding area 432, namely, the position, which indicates that the cable embedding area 432 is located on the outer side of the cable clamping area 431, so that the cable 2 can be clamped into the cable clamping area 431, and therefore the cable clamping area 431 is stably limited. The above manner is beneficial to forming a long-term stable mutual clamping connection between the cable 2 and the embedding opening, and the cable (flexible) is clamped in the cable embedding area 432 with smaller caliber by using auxiliary tools.

Further, since the cable 2 is more likely to abut against the inner cavity edge of the protection tube 1, the cable clamping area 431 can adapt to the situation and form a stable and reliable clamping action with the cable 2. Specifically, along the trend of the cable 2 (the direction of vertical penetration), the cable clamping area 431 is located in the projection range of the port of the protection tube 1, and one side of the cable clamping area 431 away from the center of the cover plate 41 (or the secondary plugging plate 44) is tangential to the projection of the inner edge of the port of the protection tube 2 on the trend of the cable 2, that is, the outer edge of the cable clamping area 431 is located in the same vertical direction with the inner edge of the port of the protection tube 2 in the same direction, so that after the cable 2 is adapted to be abutted against the inner cavity edge of the protection tube 1, the situation that no mutual limiting effect exists as far as possible from the embedded opening can be penetrated out, and thus, the longer-acting plugging effect is ensured.

In this embodiment, because the plugging mud 3 on the receiving platform forms a primary plugging, the plugging is an external plugging, the problem that the plugging part fails due to the external force action can occur, and the plugging mud 3 of the reinforcing platform forms a secondary plugging, the plugging is an internal plugging, the possibility of the external force action is reduced, in order to enable the secondary plugging to form a better plugging effect, a reinforcing space for embedding the plugging mud 3 is formed between the reinforcing platform and the cover 41, and the reinforcing space can be used for filling and filling the plugging mud 3, so that the plugging mud 3 can form a better plugging effect with the cable 2 after being compacted by extrusion. For example, the reinforcement space is a column-shaped space with one side opened (the open side is used for plugging mud 3 to enter), and the caliber of the column-shaped space is smaller than that of the port of the protection pipe 1, so that a gap which is convenient to overhaul or disassemble can be formed between the protection pipe 2 and the secondary plugging plate 44. Specifically, a partition plate 47 is formed on the side of the secondary plugging plate 44 away from the open side (the second insertion opening 45), the partition plate 47 is connected to the lower surface of the cover 41 by a fastener, and the reinforcement space is formed under the enclosure of the partition plate 47 at the connection edge 42.

In addition, the first insert opening 43 and/or the second insert opening 45 are/is communicated with the reinforcement space, and the plugging mud 3 can be filled separately or simultaneously, in this embodiment, a transition insert opening 48 is formed between the first insert opening 43 and the second insert opening 45, and the transition insert opening 48 is communicated with the reinforcement space, so that the purpose of completely plugging the first insert opening 43 and the second insert opening 45 can be achieved by filling the plugging mud from the transition insert opening 48. Specifically, the transition embedded port 48 is formed on the connection edge 42, the transition embedded port 48 includes a small-diameter port and a large-diameter port (for example, a bell mouth) that are mutually communicated, and the large-diameter port is located on one side of the small-diameter port, which is close to the reinforcement space, so that the plugging mud 3 firstly stably enters the small-diameter port during filling, then rapidly fills the whole reinforcement space in a large area through the large-diameter port, and meanwhile, the plugging mud 3 can be prevented from backfilling the small-diameter port.

In some embodiments, the inner wall of the connecting edge 42 of the side of the secondary plugging plate 44 far away from the cover 41 is provided with a tertiary plugging groove 46, the secondary plugging plate 44 is fastened on the end face of the protection tube 1, the tertiary plugging groove 46 is formed on the connecting edge 42, and the plugging mud 3 is filled to prevent foreign matters from entering the inner cavity of the protection tube 1 from the gap between the connecting edge 42 and the side face of the protection tube 1, so that the overall sealing effect of the cable 2 is affected.

Referring to fig. 5 again, the present embodiment further provides a cable protection tube port plugging assembly, which is characterized by comprising plugging mud 3 and the cable protection tube port plugging cover 4, wherein a part of the plugging mud 3 is disposed on the receiving platform and is used for coating the cable 2, a part of the plugging mud is disposed on the reinforcing platform and is used for coating the cable 2, and the remaining plugging mud is used for plugging the first embedded inlet 43 and the second embedded inlet 45, so that the purpose of fully and stably plugging the cable 2, the protection tube 1 port and the plugging cover 4 is integrally achieved

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and that descriptions of well-known components and processing techniques and procedures are omitted so as not to unnecessarily limit the present utility model.
