Description

Technical Field

[0001] The utility model relates to the field of transmission line maintenance, in particular to a fixing device for preventing foreign objects from floating in a transmission line corridor. Background Art

[0002] In recent years, with the rapid development of social economy, the power grid structure has also had to be rapidly optimized, and the line mileage has increased rapidly. However, the number of overhead transmission line corridors crossing complex environments such as urban-rural fringe areas, farmland, and garbage dumps has also continued to increase. At the same time, with the rapid development of land irrigation technology, there have been frequent incidents of foreign objects hanging on the line towers due to the drip tape being entangled in the overhead line conductors and crossarms under the line channel, which has brought tremendous pressure to the operation and maintenance of the lines.

[0003] Currently, to prevent transmission line failures caused by foreign objects hanging on drip irrigation tape during strong winds, a common practice is to organize personnel to conduct special inspections of the line corridors before or immediately after the seasonal strong winds in spring. The personnel clean up the drip irrigation tape and other foreign objects around the line corridors and bury any large areas of drip irrigation tape laid under the lines with soil. This method cannot effectively ensure the safety of the drip irrigation tape.

[0004] In response to the above pain points, through statistical analysis of the incidents in recent years where foreign objects were hanging on the transmission lines and caused transmission line failures, it was found that if the drip irrigation tape can be blocked when it is blown up and floating by the wind, the occurrence of failures can be effectively avoided. For the Chinese utility model patent with application number CN202221739007.1, the application name is "A surface drip irrigation tape fixing device". It discloses a door-shaped device that can be inserted into the ground. Although the drip irrigation tape can be fixed, in actual application, the drip irrigation tapes are staggered, and there are often two drip irrigation tapes that cross or T-cross. The cross-crossed or T-shaped crossed irrigation tapes are the nodes of the entire irrigation system, and their accurate positioning can ensure the stability of the entire irrigation system. As shown in the attached document Figure 1 If the existing surface drip irrigation tape fixing device is used for the cross drip irrigation tape shown, at least two of them are required, one for fixing the upper drip irrigation tape and two for fixing the lower drip irrigation tape. Furthermore, the surface drip irrigation tape fixing devices are relatively close together, which would require multiple closely spaced fixing spikes to be driven into the same piece of land, which could easily lead to loose soil and make it difficult to fix the fixing spikes.

[0005] Therefore, there is an urgent need for a fixing device for preventing foreign objects from floating in the transmission line corridor, which is suitable for two cross-intersecting drip irrigation belts. Utility Model Content

[0006] The utility model aims to provide a fixing device for preventing foreign objects from floating in a transmission line corridor of two drip irrigation belts that are cross-crossed or T-shaped.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] It should be noted that the terms "above", "one end", "upper", etc. used in this article indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Similar expressions are only for illustrative purposes, and do not indicate or imply that the device or element referred to 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; in addition, the terms "one part", "two parts", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] like Figure 2-3 The device shown is a fixing device for preventing foreign objects from floating in a transmission line corridor, comprising a left fixing nail 1, a right fixing nail 2, a middle rod 3, at least two sub-fixing bodies 4, and a fastener 5.

[0032] The bottom ends of the left fixing nail 1 and the right fixing nail 2 are used to be driven into the ground, and the left fixing nail 1 and the right fixing nail 2 are arranged along the left-right direction.

[0033] The middle rod 3 is used to fix the top ends of the left fixing nail 1 and the right fixing nail 2. The left fixing nail 1, the right fixing nail 2 and the middle rod 3 are all on the same plane, forming a U-shape with the opening downward.

[0034] Preferably, the middle rod 3 is arched. The left fixing nail 1, the right fixing nail 2 and the middle rod 3 can be directly processed into an integrated body by using discarded U-shaped steel.

[0035] Preferably, the middle rod 3 is perpendicular to the left fixing nail 1 or the right fixing nail 2 , and the middle rod 3 is in the shape of a long strip, which can be easily welded and fixed to the left fixing nail 1 or the right fixing nail 2 .

[0036] The sub-fixing body 4 includes sub-fixing nails and a connecting rod. The bottom end of the sub-fixing nail is used to be driven into the ground. One end of the connecting rod is connected to the top end of the sub-fixing nail. The other end of the connecting rod is connected to the intermediate rod 3. The connecting rod extends toward the intermediate rod 3. The fastener 5 fastens the connecting rod to the intermediate rod 3. The sub-fixing body 4 is generally in an inverted L-shape.

[0037] All sub-fixing bodies 4 are spaced apart and positioned on the same side of the middle rod 3, either in front of or behind the middle rod 3. The plane where the left fixing nail 1, right fixing nail 2, and middle rod 3 are located is spaced apart from the sub-fixing nails. The number of sub-fixing bodies 4 is preferably two, but this number can be varied based on actual needs.

[0038] In this way, a U-shaped space with an opening downward is formed between the sub-fixed body 4, the middle rod 3 and the left fixing nail 1 and the right fixing nail 2 on the same side as the sub-fixed body 4, which can fix another drip irrigation belt. Figure 3 The two cross drip irrigation belts are fixed in position, so that the four fixing nails can firmly fix the two cross drip irrigation belts. Figure 1 and Figure 3 As can be seen from the comparison, the existing method of fixing the three positions of the two drip irrigation belts requires six fixing nails, while this embodiment only requires four to achieve the fixation of the three positions.

[0039] Preferably, the fastener 5 includes an external thread and two nuts provided on the other end of the connecting rod. The intermediate rod 3 is provided with a through hole for the other end of the connecting rod to pass through, and the intermediate rod 3 is sandwiched between the two nuts. The other end of the connecting rod is provided with an external thread, and the two nuts are screwed onto the external thread, thereby securing the connecting rod to the intermediate rod. Furthermore, depending on the position at which the two nuts are screwed onto the connecting rod, the distance between the sub-fixing nails and the intermediate rod can be adjusted, thereby accommodating drip irrigation tapes of different diameters. Furthermore, the fastener 5 and the sub-fixing body 4 can be removed from the intermediate rod, and the left fixing nail 1, right fixing nail 2, and intermediate rod 3 can be used to pierce a film to prevent foreign matter such as the film from affecting circuit safety.

[0040] In addition, the middle rod is provided with a plurality of through holes for the other end of the connecting rod to selectively pass through. Like this, the fixed body 4 can be installed on the middle rod 3 as required, and is applicable to drip irrigation belts of different diameters.

[0041] Preferably, the left fixing nail 1, the right fixing nail 2, and the sub-fixing nails are each provided with an anti-corrosion layer to prevent them from being corroded when driven into the soil. The bottom ends of the left fixing nail 1, the right fixing nail 2, and the sub-fixing nails are all conical, making them easier to drive into the soil.

[0042] Preferably, barbs 6 are fixed on the outer sides of the left fixing nail 1 and the right fixing nail 2 respectively.

[0043] Specifically, the barbs 6 comprise two V-shaped inclined plates, the fixed ends of which are secured to the outsides of the left and right fixing nails 1 and 2, while the free ends of the inclined plates tilt upward and outward. Without the sub-fixing body 4, the left and right fixing nails 1 and 2, along with the middle rod 3, can hold the plastic film. This film, when blown by strong winds and caught in the power lines, can also pose an electrical hazard. Therefore, the plastic film needs to be secured. The lower half of the barbs is embedded in the soil, while the top can be exposed above the film, allowing the soil to cover the upper half of the barbs and secure the film. The barbs 6 provide space for the soil to settle.

[0044] This new fixing device offers the following advantages: 1. Safe and stable. The arched middle rod 3 ensures the flow of drip irrigation water while also facilitating fixation in the soil. 2. Convenient to carry: It is lightweight and convenient for carrying during inspections, without placing excessive burdens on operators. Hollow steel pipes and relatively lightweight materials were considered to minimize the structure and weight of the device. 3. Simple to operate: Installation is easy with just a hammer. 4. Easy to store: It is corrosion-resistant, extending the tool's lifespan. All surfaces of the device exposed to air are sprayed with anti-corrosion paint, and areas prone to wear are reinforced and thickened. 5. Barbs provide a secure grip in the soil. 6. In winds of force 3-5 or higher, the incidence of the drip irrigation tape flapping in the wind is significantly reduced. The drip irrigation tape fixing device effectively blocks the drip irrigation tape, preventing it from getting stuck in the tower in high winds, effectively reducing the incidence of foreign matter short-circuiting accidents within the line channel.

[0045] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
