Description

Technical Field

[0001] This utility model relates to the technical field of mobile combined flexible cables for photothermal systems, specifically to mobile combined flexible cables for photothermal systems. Background Technology

[0002] A large number of flexible cables are used in solar thermal systems. Due to their flexible nature, these cables are not easy to fix in place and require external cable ties or ropes for securing. This results in messy wiring within the system, making it difficult to inspect and clean dust, and posing potential electrical safety hazards.

[0003] Existing solar thermal systems often involve numerous flexible cables that require cable ties or ropes for securing, resulting in a messy and difficult-to-maintain system. For example, CN215577849U discloses a high-temperature resistant mobile cable with a cable core and an outer sheath. The cable core consists of a conductor and an insulation layer. The sheath has an outer aluminum alloy interlocking armor layer, which is then covered with a stainless steel wire braid. The high-temperature resistant mobile cable of this invention features an outer aluminum alloy interlocking armor layer. This interlocking armor layer forms an air insulation layer between the sheath and the cable core, preventing heat conduction and keeping the temperature outside the sheath well below the operating temperature. This ensures stable cable operation and extends cable lifespan. While the cable is very flexible and can withstand frequent bending, this design does not allow for multi-dimensional cable combinations, as multiple combinations would result in a messy and difficult-to-maintain system.

[0004] Therefore, it is necessary to invent a mobile combined flexible cable for a photothermal system to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a mobile combination flexible cable for a photothermal system, in order to solve the problem that flexible cables cannot be combined and used in combination in the current technology, and that they become messy and affect maintenance efficiency when used in large quantities in the system.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mobile combined flexible cable for a solar thermal system includes an insulating outer jacket, a first combined sleeve, a second combined sleeve, a connecting rod, a third combined sleeve, and a fourth combined sleeve. The insulating outer jacket is wrapped with a shielding mesh, and the shielding mesh is wrapped with a waterproof plastic sheet. Multiple insulating inner sleeves are set inside the waterproof plastic sheet, and each insulating inner sleeve is wrapped with a copper core. Filling sponge is placed between the multiple insulating inner sleeves. The insulating outer jacket is covered with a first combined sleeve and a second combined sleeve. Both the first combined sleeve and the second combined sleeve have limit insertion holes. The insulating outer jacket includes a fireproof coating, a high-temperature resistant coating, and a corrosion-resistant coating.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] 1. This utility model is simple to operate by fitting combination sleeves one and two onto the insulating outer sleeve and fixing combination sleeves one and two by sliding snap-fit ​​connection. Multiple connecting rods can be inserted into the limiting insertion holes on combination sleeves one and two. Combination sleeves three and four can be connected by connecting rods, and so on, so that multiple combination sleeves can be connected, so that multiple insulating outer sleeves can be used in combination, which better meets the needs of the complete set of use of the photothermal system.

[0010] 2. This utility model uses two installation and fixing methods at both ends of the connecting rod: one insertion and one rotation. This allows for better alignment and installation of multiple holes. The limiting insertion holes on the first and second combination sleeves are designed to accommodate the protrusions and balls on the connecting rod, while the threaded rod at the other end is designed to accommodate the threaded holes. These multiple connection methods improve the efficiency of installation and alignment, as well as the strength of the connection. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figures 1-3The mobile combined flexible cable for the solar thermal system shown includes an insulating outer jacket 1, a first combined sleeve 7, a second combined sleeve 8, a connecting rod 9, a third combined sleeve 10, and a fourth combined sleeve 11. The insulating outer jacket 1 is wrapped with a shielding mesh 2, and the shielding mesh 2 is wrapped with a plastic waterproof cloth 3. Multiple insulating inner sleeves 4 are set inside the plastic waterproof cloth 3. Each insulating inner sleeve 4 is wrapped with a copper core 5. Filling sponge 6 is set between the multiple insulating inner sleeves 4. The insulating outer jacket 1 is covered with the first combined sleeve 7 and the second combined sleeve 8. The insulating outer jacket 1 includes a fireproof coating 101, a high temperature resistant coating 102, and a corrosion resistant coating 103. Both the first combined sleeve 7 and the second combined sleeve 8 have limit insertion holes 801. One end of the connecting rod 9 can be inserted into the limit insertion hole 801. The other end of the connecting rod 9 is connected to the threaded hole 1002 through a threaded rod 905.

[0019] By using connecting rod 9 to connect combination sleeve 2 8 and combination sleeve 3 10, multiple insulating outer sleeves 1 are combined. Combination sleeve 1 7 and combination sleeve 2 8 form a closed ring sleeve, and combination sleeve 3 10 and combination sleeve 4 11 form a closed ring sleeve.

[0020] One end of the connecting rod 9 is provided with a protrusion 901, and the other end is connected to a threaded rod 905. A ball bearing 902 is slidably connected to the top of the protrusion 901, and the bottom of the ball bearing 902 is fixedly connected to a spring 904. A sliding plate 903 is also connected to the spring 904. The sliding plate 903 is a circular plate, and its diameter matches the inner diameter of the protrusion 901. Multiple sliding plates 903 and ball bearings 902 are provided, and the number of sliding plates 903 and ball bearings 902 is the same.

[0021] The two connection structures at both ends of the connecting rod 9 make it easy to connect the connecting rod 9 to the combination sleeve 8. Simply align the protrusion 901 and the ball 902 with the hole in the limiting insertion hole 801 and insert them. When pulling out, push or press at any position of the ball 902 to make the ball 902 retract into the protrusion 901. Under the action of multiple springs 904 and sliding plate 903, the rebound force will become slower, which will create a gap between the ball 902 and the hole, making it easy to pull the connecting rod 9 out of the limiting insertion hole 801.

[0022] Connecting rod 9 connects between combined sleeve 2 8 and combined sleeve 3 10. Combined sleeve 3 10 is semi-circular. Two end faces of combined sleeve 3 10 are provided with C-shaped sliding grooves 1001. The sliding grooves 1001 are adapted to the sliders 1101. The sliders 1101 are fixedly connected to the two end faces of the semi-circular combined sleeve 4 11. The structure of combined sleeve 4 11 and combined sleeve 3 10 is the same as that of combined sleeve 1 7 and combined sleeve 2 8. Both combined sleeve 1 7 and combined sleeve 2 8 are provided with limit insertion holes 801. The shape of the limit insertion holes 801 matches the shape of the protrusions 901 and the ball 902. Both combined sleeve 4 11 and combined sleeve 3 10 are provided with threaded holes 1002.

[0023] The sliding and fixing method between combination sleeve 1 7 and combination sleeve 2 8 is also relatively convenient. After being assembled, combination sleeve 1 7 and combination sleeve 2 8 are connected to combination sleeve 3 10 and combination sleeve 4 11 through connecting rod 9, realizing the combination of multiple insulating jackets 1, and can be combined in multiple dimensions.

[0024] Working principle of this utility model:

[0025] Refer to the instruction manual appendix Figures 1-3 When using this utility model, firstly, the first combination sleeve 7 is placed on the insulating outer sleeve 1, and the second combination sleeve 8 is slidably installed by the matching of the sliding groove 1001 and the slider 1101, and the first combination sleeve 7 and the second combination sleeve 8 are installed on the outside of the insulating outer sleeve 1.

[0026] The connecting rod 9 can be installed at any position using the limiting insertion hole 801 provided on both the first and second combination sleeves 7 and 8 (simply insert it into the position where the protrusion 901 and the ball 902 are aligned with the limiting insertion hole 801). Then, the threaded rod 905 of the connecting rod 9 is connected to the third combination sleeve 10.

[0027] Refer to the instruction manual appendix Figures 3-5 When using this utility model, multiple insulating jackets 1 can be combined by connecting the combination sleeve 3 10, the connecting rod 9, and the combination sleeve 2 8, and can be combined in any position, and multiple sets can be combined.
