[0003] In a Chinese patent publication numbered CN 219676968 U, a steam cross-linking temperature control device for cables is disclosed, which monitors the temperature at different heights to determine whether there is steam, and a transparent plate is provided to facilitate observation of the height of the sliding cylinder;

[0004] However, the above device has the following problems when used:

[0005] Only the temperature at different locations can be monitored, and the position of the temperature monitor cannot be changed. If a leak occurs inside the steam cross-linking device, and the temperature monitors that are close to the leak port are spaced a certain distance apart, steam leaks may occur. However, the initial change in the value measured by the temperature monitor is not obvious, and the leakage of the device cannot be quickly detected, resulting in a large amount of steam leakage, which wastes resources and causes uneven steam distribution inside the steam cross-linking device, resulting in the cable being unable to fully undergo a cross-linking reaction. Therefore, the present application proposes an energy-saving steam cross-linking device for cables. Utility Model Content

[0006] The purpose of the present invention is to provide a cable energy-saving steam cross-linking device to solve the problems raised by the above background technology.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-Figure 5A cable energy-saving steam cross-linking device includes a steam cross-linking box 1, one end of which is provided with an inlet and outlet 101 for the entry and exit of the cable, and a door 2 for opening and closing the inlet and outlet 101 is installed at the steam cross-linking box 1. Figure 1 、 Figure 2 There are two doors 2, and the doors 2 are connected to the steam cross-linking box body 1 through hinges. A handle is provided on the side of the door 2 away from the steam cross-linking box body 1.

[0027] The box door 2 is used to open or close the inlet and outlet 101. The box door 2 is opened by expanding outward, that is, the box door 2 expands outward. During the expansion process, it will not collide with the cables inside the steam cross-linking box 1, and the space inside the steam cross-linking box 1 can be fully utilized.

[0028] Furthermore, a steam feed pipe 3 is inserted into the steam cross-linking box 1, and the steam feed pipe 3 is connected to the steam exhaust pipe 4. The steam exhaust pipe 4 includes a plurality of transverse pipes 401 and longitudinal pipes 402 connected end to end. It should be noted that the transverse pipes 401 and the longitudinal pipes 402 are connected by bends. The transverse pipes 401 and the longitudinal pipes 402 are both installed on the inner wall of the top inner side of the steam cross-linking box 1, and steam exhaust ports 403 are evenly spaced at the bottom of the transverse pipes 401 and the longitudinal pipes 402.

[0029] The steam feed pipe 3 can deliver high-temperature steam into the steam cross-linking box 1, and heat the cable with the high-temperature steam, so that the insulation material of the cable undergoes a cross-linking reaction, thereby improving the heat resistance, wear resistance, and aging resistance of the cable. The steam exhaust pipe 4 includes multiple horizontal pipes 401 and vertical pipes 402, and the above two are connected end to end and distributed in a serpentine shape on the top of the steam cross-linking box 1. Steam is discharged through the steam exhaust ports 403 evenly spaced thereon, so that each area of ​​the steam cross-linking box 1 can be quickly filled with steam, so that the cable can be heated evenly.

[0030] To improve the thermal insulation performance of the steam cross-linking box 1, an insulation board 5 is installed inside the steam cross-linking box 1. The insulation board 5 is laid on the inside of the steam cross-linking box 1 except for the inlet and outlet 101. The steam exhaust pipe 4 is located inside the insulation board 5. By installing the insulation board 5 inside the steam cross-linking box 1, the space inside the steam cross-linking box 1 is isolated from the external environment, reducing heat exchange and thus reducing energy loss, so that the temperature inside the steam cross-linking box 1 remains consistent.

[0031] When the steam cross-linking box 1 is processing cables, a large amount of high-temperature steam needs to be filled inside it. In the process of processing the cables, steam leakage often occurs. In order to determine whether there is steam leakage inside the steam cross-linking box 1, a leakage detection frame 6 is provided inside the steam cross-linking box 1. Two leakage detection frames 6 are provided, and the two leakage detection frames 6 are respectively provided close to the two parallel side walls of the steam cross-linking box 1. The leakage detection frame 6 is connected to a traveling mechanism 8 for driving it to move in a direction perpendicular to the inlet and outlet 101. The traveling mechanism 8 can drive the leakage detection frame 6 to move deep inside the steam cross-linking box 1 or drive it to move toward the inlet and outlet 101, so that the components on the leakage detection frame 6 can measure the airflow at multiple points in the steam cross-linking box 1.

[0032] Specifically, the travel mechanism 8 includes an I-rail 801, two I-rails 801 are provided, and the two I-rails 801 are respectively located on the upper and lower inner walls inside the steam cross-linking box 1, and the I-rail 801 is slidably connected to the slider 802, and the slider 802 is equipped with a driving wheel 803 that rests on the I-rail 801, and the driving wheel 803 has a power function.

[0033] Furthermore, a first detection unit 9 and a second detection unit 10 are installed on the leakage detection frame 6. The first detection unit 9 is used to detect the airflow intensity in the direction a, and the second detection unit 10 is used to detect the airflow intensity in the direction c.

[0034] After the steam in the steam feed pipe 3 is filled into the steam cross-linking box 1, the flow of gas inside the steam cross-linking box 1 is in a dynamic equilibrium state, that is, the gas circulates and flows, and no large airflow fluctuations will occur at various places. If airflow fluctuations occur, it indicates that there is a steam leakage at that place. The first detection unit 9 is used to detect the airflow intensity in the direction a, and the second detection unit 10 is used to detect the airflow intensity in the direction c. If the airflow intensity changes significantly, it indicates that there is a leakage point. The leakage position of the steam cross-linking box 1 is usually located at the position where the internal plates are connected, that is, the area where the leakage port detection frame 6 is located. The two leakage port detection frames 6 are respectively located on both sides of the internal side wall of the steam cross-linking box 1, and can measure whether there are leakage points at the two places;

[0035] At the same time, the second detection unit 10 is facing the middle direction of the steam cross-linking box 1, that is, direction C. If the airflow in this direction changes, it means that there is a leakage in the area of ​​the steam cross-linking box 1 except the connection point of the plate. The direction of rotation of the corresponding second detection fan blade 1001 can be used to judge the direction of steam flow and thus the direction of the leakage.

[0036] Specifically, the first detection unit 9 includes a plurality of equally spaced first detection blades 901, and the first detection blades 901 are connected to a first detection mechanism for measuring their rotation speed and rotation direction. The second detection unit 10 includes a second detection blade 1001 and a second detection mechanism 1002 for measuring their rotation speed and rotation direction.

[0037] Working principle:

[0038] The cable enters the steam cross-linking box 1 through the inlet and outlet 101. The steam feed pipe 3 can deliver high-temperature steam into the steam cross-linking box 1. The high-temperature steam heats the cable, causing the insulation material of the cable to undergo a cross-linking reaction, thereby improving the heat resistance, wear resistance, and aging resistance of the cable. The steam exhaust pipe 4 includes multiple horizontal pipes 401 and vertical pipes 402, which are connected end to end and distributed in a serpentine shape on the top of the steam cross-linking box 1. Steam is discharged through the steam exhaust ports 403 evenly spaced thereon, so that each area of ​​the steam cross-linking box 1 can be quickly filled with steam, allowing the cable to be heated evenly.

[0039] During the process of steam cross-linking the cable, the traveling mechanism 8 is started. The traveling mechanism 8 can drive the leakage detection frame 6 to move deep inside the steam cross-linking box 1 or drive it to move toward the inlet and outlet 101, so that the components on the leakage detection frame 6 can measure the airflow at various points in the steam cross-linking box 1. The first detection unit 9 is used to detect the airflow intensity in direction a, and the second detection unit 10 is used to detect the airflow intensity in direction c. If the airflow intensity changes significantly, it indicates that there is a leakage point, so as to judge whether the steam inside the steam cross-linking box 1 is leaking. The staff can know the situation inside the steam cross-linking box 1 through the measurement results, respond quickly, and avoid wasting energy for a long time.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
