Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, specifically to an electrical engineering cable protection device. Background Technology

[0002] Cables are frequently used in electrical engineering. The term "cable" is a general term encompassing items such as optical fibers and electrical cables. Cables have many uses, primarily for control installations, connecting equipment, and transmitting power, among other functions.

[0003] Cables are primarily used outdoors and are frequently bent during use. The bends in the cable make it more susceptible to damage. When the cable's insulation layer breaks, rainwater and other external factors can seep into the cable, causing irreparable damage and potentially leading to short circuits and fires. Furthermore, cable joints are also vulnerable. Prolonged exposure to the elements allows dust and rainwater to enter the joints, causing corrosion, contamination, aging, and breakdown, ultimately affecting the cable's normal operation.

[0004] Existing protection devices typically consist of cylindrical or square protective shells fitted at the interface or bend. The size of the protected cable is fixed, and the bending angle and interface of the cable are fixed after the shell is fitted, which affects the cable maintenance or changes to the circuit and has low applicability. Utility Model Content

[0005] I. Technical problems to be solved

[0006] The technical problem this invention aims to solve is that the size of the protected cable is fixed, making it inconvenient to inspect or change the cable after the protective device is installed, resulting in low applicability.

[0007] II. Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: an electrical engineering cable protection device, including a protective sleeve.

[0009] The protective sleeve has an arc-shaped structure and is cylindrical. The protective sleeve can be bent at any angle. The two ends of the arc of the protective sleeve are provided with rubber rods. The diameter of the rubber rods is greater than the thickness of the protective sleeve and is integrally formed with the protective sleeve. The side walls of the two ends of the rubber rods are provided with through holes. A drawstring is inserted between the front and rear through holes for tightening the protective sleeve.

[0010] The upper sidewalls at both ends of the protective sleeve are provided with connectors, and a second drawstring is inserted between the connectors for bending the protective sleeve.

[0011] The outer wall of the protective sleeve is uniformly provided with multiple arc-shaped grooves.

[0012] Both the drawstring and the second drawstring are made of nylon. The two ends of the drawstring are fitted with a clamp and are connected to each other.

[0013] The connector is made of a rigid plate material and has a through hole on the front side that mates with the second rope. The upper corner of the connector is rounded.

[0014] One end of the second binding rope is connected to a semi-circular block, the diameter of which is larger than the diameter of the second through hole.

[0015] The length of the second gathering rope is greater than the length of the protective sleeve, and one end of the connecting semicircular block passes through the connector and is fixed in position by tying a knot.

[0016] III. Beneficial Effects

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] 1. After the protective sleeve is attached to the cable, it is secured to the cable with the help of a drawstring, which protects the cable. The size of the cable that can be used is not fixed, and the application range is wider.

[0019] 2. The protective sleeve is flexible, and the bending angle can be adjusted by the second drawstring. The protective sleeve can be bent according to the usage location. At the same time, when cable maintenance or line changes are required, the second drawstring can be reinstalled to adjust the sleeve, making the protective sleeve flexible in adjusting the degree and angle of bending, thus making it more versatile.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown,

[0027] An electrical engineering cable protection device includes a protective sleeve 1, which is an arc-shaped structure and cylindrical, and can be fitted onto the outside of the cable. The protective sleeve 1 can be bent at any angle. The protective sleeve 1 is made of rubber and has the functions of preventing electric shock and following the bending of the cable to protect the cable. The two ends of the arc of the protective sleeve 1 are provided with rubber rods 2. The diameter of the rubber rods 2 is larger than the thickness of the protective sleeve 1 and is integrally formed with the protective sleeve 1. When rainwater rolls down from the outside of the protective sleeve 1, it is blocked by the rubber rods 2 and will not enter between the two ends of the arc of the protective sleeve 1. The side walls of the two ends of the rubber rods 2 are provided with through holes 3. A coiling rope 4 is inserted between the two opposite through holes 3. A clamp 8 is fitted between the two ends of the coiling rope 4. The clamp 8 has two holes so that the two ends of the coiling rope 4 can pass through. After the clamp 8 is fitted onto the coiling rope 4, it tightens towards the protective sleeve 1 and then connects the two ends of the coiling rope 4 together. The rubber rod 2 is pressed against the cable, and the protective sleeve 1 is tightly fitted onto the cable to play a protective role.

[0028] Furthermore, the outer wall of the protective sleeve 1 is uniformly provided with multiple arc-shaped grooves 7, making the protective sleeve 1 easier to bend.

[0029] The protective sleeve 1 has connectors 5 on the upper sidewalls at both ends. A second drawstring 6 is inserted between the connectors 5. The connectors 5 are made of rigid plate material and have a through hole 9 on the front side that mates with the drawstring 6. The upper corner of the connector 5 is rounded to avoid scratching the user. One end of the drawstring 6 is connected to a semi-circular block 10. The diameter of the semi-circular block 10 is larger than the diameter of the through hole 9, so that after the drawstring 6 passes through the through hole 9 of the connector 5, one end of the semi-circular block 10 is in contact with the connector 5. The length of the drawstring 6 is greater than the length of the protective sleeve 1. The end of the drawstring 10 passes through the connector 5 and is fixed in position by knotting, so that the protective sleeve 1 can bend at the same angle as the cable, thus playing a protective role.

[0030] Furthermore, both the drawstring 4 and drawstring 6 are made of nylon, making them stronger, more durable, and less prone to breakage.

[0031] The specific usage method is as follows: Attach the protective sleeve 1 to the cable, and place the receiving rope 4 on the outside of the protective sleeve, allowing the receiving rope 4 to pass through the through hole 3. Attach the clamp 8 between the two ends of the receiving rope 4, and tighten the clamp 8 towards the protective sleeve 1 after it is placed over the receiving rope 4. Then, tie the two ends of the receiving rope 4 together. Press the rubber rod 2 against the cable, and the protective sleeve 1 will be tightly fitted onto the cable, providing protection. Pass the second receiving rope 6 through the connector 5 above the protective sleeve 1, allowing the protective sleeve 1 to bend to the same angle as the cable. The semi-circular block 10 at one end of the second receiving rope 6 is attached to the connector 5, and the other end passes through the connector 5 on the other side and is fixed in position by knotting, thus protecting the cable. The size and bending angle of the cable can be flexibly adapted, making the protective sleeve 1 more applicable. When cable maintenance or line changes are needed, adjustments can be made by reinstalling the second receiving rope 6, allowing the protective sleeve 1 to flexibly adjust the bending degree and angle as needed, making it more versatile.
