Therefore, they cannot be understood as limitations on the present invention.

[0023] In addition, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. In the description of this utility model, "plurality" means more than two, unless otherwise specifically defined.

[0024] like Figure 1-Figure 5 As shown, the utility model provides a protective hose that can be freely assembled and disassembled, including an upper arc-shaped member 10 , a lower arc-shaped member 20 , a sealing strip 30 , a plurality of upper screws 40 and a plurality of lower screws 50 .

[0025] Upper connecting bars 11 are fixedly mounted on either side of the upper curved member 10. Upper sealing grooves 13 are defined at the bottom of these bars, extending upward. Lower connecting bars 21 are fixedly mounted on either side of the lower curved member 20. Lower sealing grooves 22 are defined at the top of these bars, extending downward. A sealing strip 30 is installed between the upper and lower connecting bars 11 and 21, sealingly connecting the inner walls of both the upper and lower sealing grooves 13 and 22.

[0026] Multiple upper screws 40 are spaced apart on the upper connecting strip 11 and located on either side of the upper curved member 10. The threaded ends of the upper screws 40 pass through the upper connecting strip 11 and are threadedly connected to the sealing strip 30. Multiple lower screws 50 are spaced apart on the lower connecting strip 21 and located on either side of the lower curved member 20. The threaded ends of the lower screws 50 pass through the lower connecting strip 21 and are threadedly connected to the sealing strip 30.

[0027] During installation, the operator places the lower curved member 20 over the cable and inserts the sealing strip 30 into the lower sealing groove 22. The upper curved member 10 is then placed over the cable and the sealing strip 30 is inserted into the upper sealing groove 13, thereby enclosing the cable. Next, the operator installs all the upper screws 40 and lower screws 50. The threaded ends of the upper screws 40 pass through the upper connecting strip 11 and are then threadedly connected to the sealing strip 30. The threaded ends of the lower screws 50 pass through the lower connecting strip 21 and are then threadedly connected to the sealing strip 30. The presence of the sealing strip 30 prevents rainwater and dust from coming into contact with the cables inside, providing protection and insulation.

[0028] When disassembling the present invention, the staff removes all the upper screws 40 and the lower screws 50, and the upper arc-shaped member 10 and the lower arc-shaped member 20 can be opened, and the present invention can be taken off the cable for easy replacement. Therefore, the present invention can be quickly disassembled and assembled on the cable.

[0029] In one embodiment, the outer side of the upper connecting strip 11 is provided with a plurality of upper drainage holes 13, which are connected to the upper sealing groove 13. The outer side of the lower connecting strip 21 is provided with a plurality of lower drainage holes 23, which are connected to the lower sealing groove 22.

[0030] When some rainwater enters the upper sealing groove 13 from the gap between the upper screw 40 and the upper connecting strip 11, the rainwater will be discharged through the upper drainage hole 13. When some rainwater enters the lower sealing groove 22 from the gap between the lower screw 50 and the lower connecting strip 21, the rainwater will be discharged through the lower drainage hole 23.

[0031] The waterproof performance of the utility model is further enhanced, and the safety of the cable is improved.

[0032] In one embodiment, a downwardly inclined and outwardly extending upper guide surface 31 is formed on the top of the sealing strip 30 , and an upper cavity 14 is formed between the upper guide surface 31 and the inner wall of the upper sealing groove 13 . The upper cavity 14 is connected to the upper drainage hole 13 .

[0033] After some rainwater enters the upper cavity 14 from the gap between the upper screw 40 and the upper connecting strip 11, it will flow out from the upper drainage hole 13 under the action of the upper guide surface 31, avoiding rainwater accumulation and further enhancing the waterproof performance of the utility model.

[0034] In one embodiment, a lower guide surface 32 that is inclined upward and extends outward is formed at the bottom of the sealing strip 30 . A lower cavity 24 is formed between the lower guide surface 32 and the inner wall of the lower sealing groove 22 . The lower cavity 24 is connected to the lower drainage hole 23 .

[0035] After some rainwater enters the lower cavity 24 from the gap between the lower screw 50 and the lower connecting strip 21, it will flow out from the lower drainage hole 23 under the action of the lower guide surface 32, avoiding rainwater accumulation and further enhancing the waterproof performance of the utility model.

[0036] In one embodiment, the upper arc-shaped member 10 and the lower arc-shaped member 20 are both made of PE polyethylene material.

[0037] In this embodiment, the upper connecting bar 11 and the lower connecting bar 21 are both made of PE polyethylene material.

[0038] PE is corrosion-resistant, and its molecular structure is highly stable. It is resistant to chemical corrosion from natural gas, liquefied petroleum gas, and manufactured coal gas, eliminating the need for secondary corrosion protection equipment. Furthermore, it does not promote the growth of algae, bacteria, or fungi, significantly reducing the failure rate of solar power systems and reducing additional operation and maintenance costs.

[0039] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all points of view, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
