Description

Technical Field

[0001] The present disclosure relates to the technical field of anti-collision devices for power transmission, and more particularly, to an anti-collision device for transmission and distribution lines. Background Art

[0002] Transmission and distribution lines are lines for transmitting electric energy erected between power plants and regional substations, and between regional substations. They are characterized by high line voltage, long transmission distance, and large transmission capacity. The anti-collision device for transmission and distribution lines is used to prevent collisions between lines, which may cause line damage or even lead to safety accidents. However, according to investigations, the existing anti-collision devices for transmission and distribution lines often have the following problems:

[0003] 1. Installing anti-collision devices on each transmission cable in sequence not only has low efficiency, but also after installing the anti-collision devices, in a strong wind environment, intense collisions still occur between multiple transmission cables, and the cables hitting each other are easily broken, which is likely to cause power transmission safety accidents;

[0004] 2. For multiple cables, it is necessary to position and clamp each cable separately in sequence, and when clamping each cable, a fixed method using fastening bolts is required, making the overall operation steps cumbersome, thus reducing work efficiency;

[0005] 3. Most of the existing anti-collision devices are of a closed structure, that is, only one end of the cable can be passed through and clamped when the cable is being installed. Over time, with the gradual wear and corrosion of the anti-collision device, when the anti-collision device is damaged, it cannot be replaced, which has great limitations.

[0006] In view of this, the inventor proposes an anti-collision device for transmission and distribution lines. Utility Model Content

[0007] The purpose of the present disclosure is to provide an anti-collision device for transmission and distribution lines. This device forms a closed annular sleeve through the mutual engagement of a movable snap ring and a fixed snap ring, thereby realizing clamping of the cable, preventing collisions between cables, not only improving the protection effect on the cable, but also being more convenient to use and improving work efficiency.

[0008] To achieve the above object, the present disclosure provides an anti-collision device for transmission and distribution lines, which includes an anti-collision wheel and a plurality of locking mechanisms connected to the anti-collision wheel. The locking mechanism includes a movable snap ring, a fixed snap ring, and a locking component installed in the fixed snap ring; one end of the fixed snap ring is detachably connected to the anti-collision wheel, the other end of the fixed snap ring is hinged to one end of the movable snap ring, and the other end of the movable snap ring can be inserted into the fixed snap ring near one end of the anti-collision wheel and is snap-connected to the locking component.

[0009] Optionally, the locking assembly includes a lever, a locking spring and a locking rack. A chute and an installation cavity communicating with the chute are provided in the fixed snap ring. The locking rack is installed in the installation cavity through the locking spring. A tooth engaging with the locking rack unidirectionally is provided on the movable snap ring. A limiting groove communicating with the installation cavity is further formed in the fixed snap ring. One end of the lever is connected to the locking rack, and the other end of the lever is a hand-held end.

[0010] Optionally, a limiting tube is arranged on the circumference of the anti-collision wheel. A limiting protrusion is arranged at one end of the fixed snap ring away from the movable snap ring. A limiting hole engaging with the limiting protrusion is provided on the limiting tube.

[0011] Optionally, the locking mechanism further includes a telescopic rod. The telescopic rod includes an outer tube, an inner rod, a limiting block and a telescopic spring. The inner rod is sleeved in the outer tube and connected through the telescopic spring. The limiting block is arranged on the inner rod located inside the outer tube. One end of the inner rod away from the telescopic spring is connected to the fixed snap ring, and one end of the outer tube away from the inner rod is connected to the limiting protrusion.

[0012] Optionally, there are multiple limiting tubes, and the multiple limiting tubes are evenly arranged along the circumference of the anti-collision wheel.

[0013] Optionally, one end of the fixed snap ring and the anti-collision wheel are connected through an eccentric wheel nut and an eccentric rod.

[0014] Optionally, the limiting protrusion is made of plastic.

[0015] Through the above technical solutions, firstly, in this device, the cable is placed in the fixed snap ring, and the mutual engagement of the movable snap ring and the fixed snap ring forms a closed annular sleeve, thereby clamping and fixing the cable so that the cable is wrapped and will not collide, improving the protection effect on the cable. Secondly, by rotating the movable snap ring and cooperating with the locking assembly, locking or loosening can be achieved, greatly simplifying the operation steps, making the use more convenient, and thus improving the work efficiency. Finally, since the anti-collision wheel and the fixed snap ring are detachably connected, it is convenient to carry and replace the whole device, thereby improving the adaptability of this device.

Detailed description of the specific implementation mode

[0024] The following will describe the specific implementation mode of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific implementation mode described herein is only for the purpose of illustration and explanation of the present disclosure, and is not used to limit the present disclosure.

[0025] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower, left, right" are usually defined based on the direction of the drawing surface of the accompanying drawings, and "inner, outer" refer to the inner and outer of the relevant components.

[0026] In the description of the present disclosure, it should also be noted that unless otherwise clearly defined and limited, the terms "set" and "connected" 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 directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0027] The present disclosure provides an anti-collision device for power transmission and distribution lines. Please refer to Figures 1 - 3, which includes a collision avoidance wheel 100 and a plurality of locking mechanisms connected to the collision avoidance wheel 100. The locking mechanism includes a movable snap ring 110, a fixed snap ring 120, and a locking component installed in the fixed snap ring 120; one end of the fixed snap ring 120 is detachably connected to the collision avoidance wheel 100, the other end of the fixed snap ring 120 is hinged to one end of the movable snap ring 110, and the other end of the movable snap ring 110 can be inserted into the fixed snap ring 120 near one end of the collision avoidance wheel 100 and is snap-connected to the locking component.

[0028] In the above technical solution, the main body of the entire anti-collision device is made of cis-butadiene rubber material. Cis-butadiene rubber is the second largest synthetic rubber after styrene-butadiene rubber. Compared with natural rubber and styrene-butadiene rubber, it has particularly excellent cold resistance, wear resistance and elasticity after vulcanization, less heat generation under dynamic load, good aging resistance, and is easy to be used in combination with natural rubber, chloroprene rubber or nitrile rubber. The product made of cis-butadiene rubber material can reduce the erosion of rainwater in the external environment to the product due to being in the outdoor environment of sun exposure and rain for a long time, and is not easy to lose the fastening and connection functions due to degradation and oxidation. In some other embodiments, materials such as ethylene-propylene rubber or isoprene rubber can also be used.

[0029] Among them, the movable snap ring 110 and the fixed snap ring 120 are composed of two semi-circular snap rings with the same diameter. One of them is the fixed snap ring 120, and the other is the movable snap ring 110. The upper end of the fixed snap ring 120 and the lower end of the movable snap ring 110 are hinged together to form a ring sleeve for wrapping the cable. In actual use, when the two semi-circular snap rings are joined together, it is convenient for the upper end of the movable snap ring 110 to be caught in the lower end of the fixed snap ring 120 and snap-connected and locked with the locking component, so that the locking mechanism can be firmly fixed on the cable. Then, by connecting the plurality of locking mechanisms to the collision avoidance wheel 100 respectively, the fixation of the cable can be realized.

[0030] Optionally, in an embodiment of the present disclosure, please refer to Figure 1 and Figure 3 , the locking component includes a lever 130, a locking spring 140 and a locking rack 150. A chute 121 and an installation cavity 122 communicating with the chute 121 are provided in the fixed snap ring 120. The locking rack 150 is installed in the installation cavity 122 through the locking spring 140; the movable snap ring 110 is provided with teeth that cooperate unidirectionally with the locking rack 150. A limiting groove communicating with the installation cavity 122 is also opened on the fixed snap ring 120. One end of the lever 130 is connected to the locking rack 150, and the other end of the lever 130 is a hand-held end.

[0031] In the above technical solution, a locking tooth is provided on the upper side wall of the movable snap ring 110, and an installation cavity 122 is provided inside the lower end of the fixed snap ring 120. The installation cavity 122 communicates with the chute 121. A locking spring 140 and a locking rack 150 are installed in the installation cavity 122. The side of the locking rack 150 with teeth faces the direction of the chute 121. The lower end of the locking spring 140 is connected to the side wall of the installation cavity 122, and the upper end of the locking spring 140 is connected to the locking rack 150. The locking spring 140 can elastically support the locking rack 150, so that the locking rack 150 is tightly engaged with the locking teeth of the movable snap ring 110, enhancing the locking function of the locking rack 150 on the locking teeth.

[0032] When the locking teeth of the movable snap ring 110 are engaged with the locking teeth, the movable snap ring 110 cannot exit outside the chute 121 and can only move into the chute 121. In this way, the diameter of the annular sleeve can be reduced, and the locking mechanism can be firmly fixed on the cable to prevent it from falling off.

[0033] A limiting groove communicating with the installation cavity 122 is formed in the side wall of the fixed snap ring 120. One end of the dial rod 130 passes through the limiting groove and is connected to the locking rack 150. The dial rod 130 can slide along the path of the limiting groove. When it is necessary to disassemble the locking mechanism from the cable, the user can use the hand to move the locking rack 150 away from the chute 121 through the dial rod 130, so that the locking rack 150 is separated from the locking teeth of the movable snap ring 110. In this way, it is convenient to take out the movable snap ring 110 from the chute 121, providing great convenience for subsequent cable inspection and maintenance.

[0034] Optionally, in an embodiment of the present disclosure, please refer to Figure 1 , a limiting tube 160 is provided on the circumference of the anti-collision wheel 100, a limiting protrusion 170 is provided at one end of the fixed snap ring 120 away from the movable snap ring 110, and a limiting hole 161 engaged with the limiting protrusion 170 is provided on the limiting tube 160. When the locking mechanism is fixed on the cable, it is only necessary to insert the limiting protrusion 170 forcefully into the limiting tube 160 until the locking state is reached, making the operation more convenient.

[0035] Optionally, in some other embodiments of the present disclosure, the limiting protrusion 170 can also be made of plastic. When the plastic limiting protrusion 170 is inserted into the limiting tube 160, it will be slightly deformed. After it completely enters the limiting hole 161, the limiting protrusion 170 resumes its deformation to achieve locking.

[0036] Optionally, in some other embodiments of the present disclosure, please refer to Figure 1 , there are multiple limiting tubes 160, and the multiple limiting tubes 160 are evenly arranged along the circumference of the anti-collision wheel 100, which is convenient for connecting multiple locking mechanisms.

[0037] Optionally, in an embodiment of the present disclosure, please refer to Figure 3 and Figure 4 , the locking mechanism further includes a telescopic rod, which includes an outer tube 180, an inner rod 190, a limiting block 200 and a telescopic spring 210. The inner rod 190 is sleeved inside the outer tube 180 and is connected by the telescopic spring 210; the limiting block 200 is arranged on the inner rod 190 located inside the outer tube 180; one end of the inner rod 190 away from the telescopic spring 210 is connected to the fixed clamping ring 120, and one end of the outer tube 180 away from the inner rod 190 is connected to the limiting protrusion 170.

[0038] In the above technical solution, the lower end of the outer tube 180 is in a closed state, and the upper end of the outer tube 180 is in an open state. The lower end of the inner rod 190 passes through the upper end of the outer tube 180 and enters the outer tube 180. At the same time, the lower end of the inner rod 190 and the inner wall of the lower end of the outer tube 180 are connected by the telescopic spring 210 to achieve elastic telescoping. To prevent the inner rod 190 from sliding out of the outer tube 180, a limiting block 200 is provided at the lower end of the inner rod 190. The limiting protrusion 170 is connected to the outer wall of the lower end of the outer tube 180, and the upper end of the inner rod 190 is connected to the fixed clamping ring 120. The telescopic rod can not only solve the problem of inconsistent spacing between different cables, but also play a certain buffering role for the cables.

[0039] Optionally, in an embodiment of the present disclosure, one end of the fixed clamping ring 120 is connected to the anti-collision wheel 100 through an eccentric nut and an eccentric rod. The eccentric nut and the eccentric rod are common connectors in the furniture industry, and their costs are low. After being adopted by this device, the anti-collision wheel 100 and the locking mechanism can still be quickly installed and disassembled.

[0040] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
