DETAILED DESCRIPTION
[0019] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.
[0020] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "vertical", "cross", "inside", "outside", "front", "back" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0021] like Figure 1 to Figure 2As shown, an embodiment of the present invention proposes a wire tree protection device, including an open protection tube 1, an open connector male head 2 and an open connector female head 3. The open protection tube 1 is provided with an opening 11 along one side of the axis, and the open connector male head 2 and the open connector female head 3 are respectively arranged at both ends of the open protection tube 1; the open connector male head 2 can be inserted into the open connector female head 3 to form a snap-on connection.
[0022] By sleeve-mounting the open protection tube 1 on the conductor 6 through the opening 11, the conductor 6 is protected, and the insulation problem of the bare conductor of the distribution line crossing over the forest is solved; further, Figure 5 As shown, by arranging an open connector male head 2 and an open connector female head 3 at both ends of the open protection tube 1, the open connector male head 2 at the end of another open protection tube 1 is connected with the open connector female head 3 on the wire, thereby realizing continuous installation of the open protection tube 1.
[0023] like Figure 3 , Figure 4 As shown, the wire crossing tree protection device also includes a first lock core type self-locking structure 4 and a second lock core type self-locking structure 5; the first lock core type self-locking structure 4 and the second lock core type self-locking structure 5 are respectively arranged on the open connector male head 2 and the open connector female head 3, and are used to limit the axial movement and radial rotation of the protection device on the wire.
[0024] The first lock core type self-locking structure 4 and the second lock core type self-locking structure 5 can make the installation of the open connector male head 2 and the open connector female head 3 more stable, and make the open protection tube 1 unable to move, thereby playing a limiting role.
[0025] Furthermore, the first lock core type self-locking structure 4 and the second lock core type self-locking structure 5 each include a mounting frame 41, a spring 42 and a locking block 43. The mounting frame 41 is used to connect with the open connector male head 2 or the open connector female head 3, and the locking block 43 is connected with the mounting frame 41 through the spring 42. Through the elastic action of the spring 42, the locking block 43 is installed and inserted into the gap of the wire 6, and through the one-way locking mechanism, it is ensured that the protective device on the wire 6 will not slide left and right along the wire due to wind force or other external forces.
[0026] Furthermore, the lock block 43 has an inclined surface, and the inclined surface faces the side of the open connector male connector 2 or the open connector female connector 3 with an opening. The setting of the inclined surface on one side of the lock block 43 ensures that the connection between the open protection tubes 1 will not be affected. It should be noted that in this embodiment, the length of the open protection tube 1 is 3 meters. Since the length of the wire 6 is long, the open protection tube 1 is set to 3 meters to adapt to the length of the wire 6.
[0027] The end of the locking block close to the wire 6 is a sharp tip, and the sharp tip is used to embed into the gap on the surface of the wire 6. By embedding the sharp tip of the locking block into the surface of the wire 6, the protection device is prevented from rotating around the wire 6, and the stability of the installation position is maintained.
[0028] It should be noted that the male connector 2 has a protrusion, and the female connector 3 has a groove. The male connector 2 and the female connector 3 are connected by the protrusion and the groove. The function of the male connector 2 and the female connector 3 is to connect multiple sections of protection to form a continuous protective structure. After the male connector 2 is inserted into the female connector 3, the mechanical connection is achieved by the protrusion and the groove. The lock core self-locking structure makes up for the shortcomings of the simple mechanical connection by physically biting the surface of the wire, providing double insurance.
[0029] In this embodiment, the material of the opening protection tube 1 is a weather-resistant insulating material, and its inner wall is provided with anti-skid patterns to fit the surface of the wire 6. The provision of the weather-resistant insulating material prevents the wire 6 from directly contacting with external objects for conduction, and the anti-skid patterns ensure the stability of the opening protection tube 1 during installation.
[0030] The construction method of the wire tree protection device comprises the following steps: Step 1: Install the first lock core type self-locking structure 4 at the left end of the open connector male head 2 of the first open protection tube 1, put the open protection tube 1 on the wire 6 through the opening along the axis, and push the open protection tube 1 along the wire 6 along the notch of the locking block 43; Step 2: Install multiple open protection tubes 1 along the axial direction of the wire, and clamp the open connector male head 2 and the open connector female head 3 between the open protection tubes 1 together; Step 3: After reaching the required length, install the last open protection tube 1, and install the second lock core type self-locking structure 5 in the open connector female head 3 of the last open protection tube 1. This makes the entire wire tree protection device locked and fixed in the axial direction.
[0031] The product has an open structure. The installer will split the protective tube on the pole on one side of the line, put it on the wire, and insert the male open connector of the second wire into the female open connector of the first wire to achieve continuous installation of the protective tube. The installer does not need installation tools such as boom trucks and scaffolding. After climbing the pole, the installer will install the wire from one side. One or more wire tree protection devices can be installed. The operation is simple and easy to use.
[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention are understood according to specific circumstances.
[0033] The above specific embodiments are only one or several preferred embodiments of the present invention.
