Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line dancing suppression, in particular to an assembled power transmission line anti-dancing device. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Transmission line galloping refers to a low-frequency, large-amplitude self-excited vibration phenomenon caused by uneven ice coverage on the transmission line conductors under the action of wind. Transmission line galloping is often accompanied by severe weather such as ice coverage and strong winds. Galloping can cause the hardware, insulating components and bolts in the transmission line to loosen or even fall off, accelerate wear or even break. The stress generated by galloping can cause excessive wear of the conductors, instability of the transmission tower body and foundation, and reduce the gap between the conductor and the ground wire, triggering a short circuit accident.

[0004] In order to cope with the impact of dancing, common anti-dancing devices include phase spacers, damping wires, anti-dancing devices, etc. Most of these devices are pre-installed, that is, they are pre-installed at the required position during the construction of the transmission line. For some transmission lines in operation, it is difficult to install them on the transmission lines in operation due to the structure and installation method of the pre-installed anti-dancing devices.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] It should be noted that the following detailed descriptions are exemplary and are intended to provide further description of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0027] Terminology explanation:

[0028] Transmission line galloping: A low-frequency, large-amplitude self-excited vibration phenomenon caused by wind when the transmission line conductors are unevenly covered with ice. This galloping can cause damage to the transmission line and even cause accidents. The main reason for the galloping is that the conductors are subjected to uneven aerodynamic forces, causing the conductors to vibrate self-excitedly.

[0029] Anti-dancing device: A device that effectively suppresses dancing and is widely used in power engineering. By installing an anti-dancing device on the conductor, the conditions for the formation of dancing are destroyed and the occurrence of dancing is suppressed. Common anti-dancing devices include interphase spacers, damping wires, anti-dancing devices, etc.

[0030] The following embodiment provides an assembled transmission line anti-dancing device. According to the actual needs of the line, a certain number of counterweight devices are selected to fix the anti-dancing wire. The setting position can be freely changed and the size of the counterweight can be adjusted, thereby reducing the configuration cost of the anti-dancing device.

[0031] like Figure 1-Figure 2 As shown, an assembled transmission line anti-dancing device comprises:

[0032] A pull wire 2, one end of which is connected to the conductor 1, and the other end of which is connected to the receiving bag 3;

[0033] There is at least one mass bag 4 , which is filled with a set weight, and a set number of mass bags 4 are arranged in the receiving bag 3 .

[0034] In this embodiment, a fixed point is set on the containing bag, and it is detachably connected to the pull line through the fixed point; the containing bag is used to contain multiple mass bags to form a counterweight, and the mass bag provides a set amount of pulling force by loading fillers of set weight.

[0035] The anti-dancing pulling force of the transmission line is relatively large, which can reach several tons of force. Different levels of transmission lines have different anti-dancing pulling forces. The counterweight end of the existing prefabricated anti-dancing device is usually fixed on the ground, and it is necessary to lay a foundation on the ground and make cement counterweights to improve stability. The construction cost is high, and after production, it may be idle for a long time and cannot be moved, which increases installation and maintenance costs, and is inflexible to use.

[0036] In this embodiment, the counterweight structure used for pulling the anti-dancing wire is set as a soft containing bag. Different numbers of mass bags with fillers are placed in the containing bag according to the actual anti-dancing pulling force requirements. The fillers are locally sourced according to the location of the wire (for example, solids such as fine sand and soil). The mass bags and the containing bag can be bags made of canvas material, which can be folded for transportation, making them easy to carry. Since the fillers are locally sourced, they can be emptied on the spot after use, thereby reducing costs by reuse.

[0037] For example, 20 cubic mass bags are prepared using canvas, each of which is 2 meters in length, width and height respectively. After being filled with fine sand, each mass bag weighs 50 kg. Another holding bag that can withstand at least 1 ton of tension is prepared. One end of the pull wire is hung on the wire, and the other end is connected to the holding bag. The shape, size and weight of the holding bag can be changed by changing the number of mass bags loaded, thereby changing the counterweight. The change in the counterweight can be used to adjust the tension transmitted to the wire through the pull wire, thereby meeting different anti-dancing needs.

[0038] The pull wire can be made of high-strength insulated rope, one end of which is thrown and hung on the conductor, and the other end is connected to the containing bag to achieve line anti-dancing.

[0039] There is no limitation on the specific structure of the containing bag and the mass bag. They can be made of wear-resistant materials and can meet the tension requirements. For example, in this embodiment, they are made into a structure of inner and outer layers, wherein the inner layer has a reinforcement layer and the outer layer has a wear-resistant layer.

[0040] The guy wires are set on the transmission line. By setting a certain number and position of guy wires on the transmission line, cooperating with the counterweight formed by the containing bag and the mass bag, the dynamic characteristics of the line are changed, thereby achieving the effect of anti-dancing.

[0041] Optionally, when the filler in the mass bag is liquid, rubber, rubber-like or other materials capable of storing liquid can be used to process the bag into a bag shape. For example, the liquid storage bag includes an inner layer and an outer layer, the inner layer can be made of rubber or plastic material, and the outer layer is made of fabric; the manufacturing process of the liquid storage bag can adopt methods such as thermoforming or injection molding to obtain the desired shape and structure of the liquid storage bag.

[0042] Optionally, the plastic material can be polyethylene (PE) or polyvinyl chloride (PVC), etc. These plastic materials have excellent chemical resistance and mechanical strength and are suitable for the manufacture of liquid storage bags.

[0043] Another structure that can be realized is to use rubber-plastic composite materials to manufacture mass bags. Rubber material is used in the inner layer of the mass bag, and plastic material is used in the outer layer to meet the storage and appearance requirements of liquids at the same time. The manufacturing process of rubber-plastic composite mass bags can be laminated or co-extruded to compound rubber and plastic materials.

[0044] A further technical solution is to add a fabric reinforcement layer inside the rubber or plastic mass bag, and the fabric reinforcement layer can be made of polyester fiber or nylon fabric. The manufacturing process can first manufacture the rubber or plastic mass bag, and then bond the fabric reinforcement layer to the mass bag to form a reinforced structure.

[0045] In this embodiment, a fabric reinforcement layer is provided to enhance the strength and durability of the liquid storage bag and prevent over-expansion and rupture.

[0046] The fabric-reinforced quality bag is set to form a multi-layer structure, and each layer uses different materials to meet various requirements; the inner layer uses rubber material to ensure the sealing of the liquid filler, the middle layer uses fabric-reinforced material to increase strength, and the outer layer uses plastic material with good wear resistance. The manufacturing process can use methods such as co-extrusion molding or lamination molding to laminate different materials together to form a multi-layer structure.

[0047] The mass bag provided in this embodiment is reusable and uses durable materials and structures to facilitate multiple uses and cleanings. Thick rubber or plastic materials are used to strengthen the stitching and connection parts. The manufacturing process focuses on the durability of the materials and the firmness of the structure to ensure the long-term use and reliability of the liquid storage bag.

[0048] Optionally, the mass bag is provided with a sealable opening;

[0049] When the filling material in the quality bag is liquid, a safety valve or a pressure gauge should be installed;

[0050] In some embodiments, the shape of the mass bag can be a cube, a cuboid, a cylinder, or other different shapes; the shape of the mass bag is the final shape after being filled.

[0051] In other embodiments, the mass bag may be made into a pressure-bearing mass bag or a non-pressure-bearing mass bag according to different materials;

[0052] Among them, there are pressure quality bags that need to be injected with high-pressure injection devices. There is a certain pressure in the bag, and the pressure in the bag cannot break the quality bag; high-pressure injection devices such as high-pressure water guns;

[0053] In most cases, unpressurized mass bags filled with solid fill are preferred.

[0054] The fixed points on the containing bag serve as lifting points, which can bear the weight of the entire mass bag and the tension during the lifting process. The high-strength sling can be reliably connected to the containing bag; the high-strength sling can also be processed together with the containing bag; and insulating materials can be used to make fixed lifting points of fixed structure.

[0055] The rated pulling force generated by the containment bag can be set at a pulling force above 0.5 tons;

[0056] When in use, the device is transported to the corresponding location, connected to the pull wire, and the anti-dancing tension is calculated according to the level of the transmission line. The total weight and total volume of the containing bag are determined, the corresponding number of mass bags are selected, and the corresponding weight of fillers are filled. When the abnormal weather ends, the fillers can be directly released or recycled. If it is water, it can be directly released into the wild to achieve water recycling; if it is soil material, it can be backfilled to the original material collection site.

[0057] By setting the counterweight structure to a structure with variable quantity, weight and position, the shape and size can be changed by different specifications and quantities of the mass bags installed, and the tension of the pull wire can be flexibly adjusted. The filling in the mass bag can be made from local materials, which is easy to transport and install, and is low-cost and reusable.

[0058] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0059] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
