[0035] In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, and the like, unless otherwise explicitly and specifically limited. All directional indications, such as upper, lower, left, right, front, back, top, bottom, and the like, are used with respect to the orientation of the figure as shown in the attached drawings, and are made only for the purpose of illustrating and describing the present application. There is no intention that the application be limited to the exact orientation shown in the figures. In addition, the terms "include" and "have" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or device that includes a list of steps or units is not limited to the listed steps or units, but can optionally include additional steps or units not listed, or can optionally include other steps or units inherent to such processes, methods, products, or devices.

[0036] In addition, reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor does it necessarily refer to a particular embodiment that is "preferred" over other embodiments. It will be explicitly understood that the embodiments described herein can be combined with other embodiments in various ways.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] Figure 1 The diagram shown is a structural schematic of an optical cable fixing device according to an embodiment of the present invention. Figure 2 The diagram shown is a structural schematic of an optical cable fixing device according to another embodiment of the present invention. Figure 1 , 2 As shown, the optical cable fixing device includes;

[0039] The main clamp 100 is arc-shaped and is fixedly installed on the tower 500.

[0040] The secondary clamp 200 is located directly above the main clamp 100, and the secondary clamp 200 is connected to the main clamp 100 by multiple fixed connecting rods 300.

[0041] The upper end of the fixed connecting rod 300 is fixed to the auxiliary clamp 200. After the auxiliary clamp 200 is lifted to a designated position by the clamp lifting mechanism 400, the lower end of the fixed connecting rod 300 is fixed to the main clamp 100. That is, the main clamp and the auxiliary clamp connected by the fixed connecting rod form the optical cable fixing device.

[0042] In this embodiment, the shape and size of the main clamp 100 match the shape and size of the pole 500 in the power transmission system. The main clamp 100 and the pole 500 fit together perfectly so that the main clamp 100 can be stably fitted onto the pole 500 without slipping after being tightened.

[0043] Modern power poles are generally circular, thicker at the bottom and thinner at the top. The main clamp and auxiliary clamp are typically installed at the top of the pole, therefore their size is consistent with the top of the pole.

[0044] In addition, during the installation of the main clamp, in order to make the main clamp fit more stably with the tower, a flexible washer can be placed between the tower and the main clamp. This flexible washer has the properties of corrosion resistance, rain resistance and high temperature resistance.

[0045] Specifically, refer to Figure 3 , Figure 3 The diagram shown is a structural schematic of the main clamp of an optical cable fixing device according to another embodiment of the present invention. Figure 3As shown, the main hoop 100 comprises a semicircular first hoop piece 110 and a second hoop piece 120 symmetrically arranged with the first hoop piece 110; the first hoop piece and the first hoop piece are arc-shaped, not only beautiful in shape, but also matching the shape of the tower. The first hoop piece 110 and the second hoop piece 120 can surround the tower 500 by being respectively closed from both sides of the tower 500, that is, the first hoop piece 110 and the second hoop piece 120 can just surround the tower 500 for one turn, and the first hoop piece 110 and the second hoop piece 120 form a circle after being closed, which is well fitted with the tower, and then fixed on the tower. This fixing method is simple and easy to use, and does not need special operation training for the operating personnel, and can be used for large-area popularization and promotion.

[0046] The first hoop piece 110 is provided with outwardly folded first and second connecting pieces 111 and 112 at both ends, and the second hoop piece 120 is provided with outwardly folded third and fourth connecting pieces 121 and 122 at both ends; wherein the first connecting piece 111 is connected with the third connecting piece 121 in alignment through a fixing piece 150, and the second connecting piece 112 is connected with the fourth connecting piece 122 in alignment through the fixing piece 150. The fixing piece 150 can be a screw and nut assembly, or a buckle component.

[0047] The first hoop piece 110 and the second hoop piece 120 are both made by an integrated casting process, so that the required mold is less and the quality of the finished hoop piece is higher, which can not only save cost but also meet the requirements of fixing optical cables.

[0048] It can be understood that the ends of the first connecting piece 111, the second connecting piece 112, the third connecting piece 121 and the fourth connecting piece 122 can be provided with arc structures. Since the main hoop is made of metal, compared with sharp right-angle structures, the arc structures can avoid accidentally scratching the operating personnel, further improving the safety during transportation and operation. The manufacturing process is very mature in today's era, and setting the arc shape will not significantly increase the production process difficulty, nor increase the manufacturing cost or raw material cost.

[0049] Since the main function of the first connecting piece 111 and the second connecting piece 112 of the first hoop piece 110 and the third connecting piece 121 and the fourth connecting piece 122 of the two ends of the second hoop piece 120 is to serve as the connecting component of the first hoop piece 110 and the second hoop piece 120, and further to fix the main hoop on the tower. Therefore, in other embodiments, the main hoop 100 can also be designed as a U-shaped clamp structure (not shown in the figure), and one connecting piece is extended from each end of the U-shaped clamp. The size of the annular part of the U-shaped clamp is designed to be the same as the size of the upper end of the tower 500, and the U-shaped clamp has a certain elasticity. When installing, the two ends of the U-shaped clamp are pulled apart to be clamped into the tower, and then the two ends of the U-shaped clamp are connected by using a screw or other fixing member. In this way, the main hoop of the U-shaped clamp structure can be fixed to the tower. The U-shaped clamp structure can be directly fixed to the tower, which has the characteristics of simplicity and convenience.

[0050] Referring to Figure 4 , Figure 4 Fig. 6 shows a schematic diagram of a fixing connecting rod structure of a cable fixing device according to another embodiment of the present application. The lower end of the fixing connecting rod 300 is provided with a plurality of first through holes 310, and the upper end of the fixing connecting rod 300 is provided with a second through hole 320. The shapes of the plurality of first through holes 310 and the second through hole 320 are the same as the shape of the connecting hole, which is generally circular, and the inner diameter thereof can be set to 8-15 mm. Among them, after aligning the first connecting piece 111, one of the plurality of first through holes 310, and the second connecting piece 112, the first connecting hole 140 on the first connecting piece 111, one of the plurality of first through holes 310, and the first connecting hole 140 on the second connecting piece 112 are in communication, and the fixing member 150 can be inserted thereinto. The plurality of first through holes 310 are respectively arranged at different heights, for example, the distances of the first through holes from the bottom end are 2 cm, 5 cm, 10 cm, 15 cm, 20 cm, and 30 cm. It can be understood that the distance required between the main hoop and the auxiliary hoop in actual application is not fixed. In order to meet different actual operation requirements, under the condition that the length of the fixing connecting rod is fixed, the distance between the main hoop 100 and the auxiliary hoop 200 can be adjusted by selecting the first through hole 310: if the first through hole 310 close to the lower end of the connecting fixing rod is selected, the distance between the main hoop 100 and the auxiliary hoop 200 is long, and vice versa. In addition, the total length of the fixing connecting rod 300 can be set to 50 cm, 80 cm, or 100 cm according to requirements.

[0051] In order to simplify the production process of the fixed connecting rod 300, a plurality of fixed connecting rods 310 of different lengths can be provided, for example, a batch of 50 cm, 80 cm or 100 cm fixed connecting rods 310 of different lengths are produced respectively. In this way, only one or two first through holes 310 can be provided.

[0052] In actual installation, the fixing member 150 is sequentially inserted through the first connecting hole 140 provided on the first connecting piece 111, one of the plurality of first through holes 310, and the first connecting hole 140 provided on the second connecting piece 112. After the fixing member 150 is fastened, the lower end of the fixed connecting rod 300 can be fixed to the main hoop 100.

[0053] The structure of the auxiliary hoop 200 is the same as that of the main hoop 100, as shown in Figure 2 The auxiliary hoop 200 includes a third hoop piece 210 and a fourth hoop piece 220 arranged symmetrically, the two ends of the third hoop piece 210 are provided with outwardly folded fifth and sixth connecting pieces, the two ends of the fourth hoop piece 220 are provided with outwardly folded seventh and eighth connecting pieces, the fifth connecting piece is connected to the seventh connecting piece by the fixing member 150, and the sixth connecting piece is connected to the eighth connecting piece by the fixing member 150.

[0054] The third hoop piece 210 and the fourth hoop piece 220 are made by an integrated casting process, so that fewer molds are required and the quality of the finished hoop piece is higher, which can save costs and meet the requirements of fixing optical cables.

[0055] Understandably, the ends of the fifth, sixth, seventh and eighth connecting pieces can be provided with a circular arc structure to prevent scratching accidents.

[0056] In installation, the third hoop piece 210 and the fourth hoop piece 220 of the auxiliary hoop 200 are enclosed from both sides of the tower 500, and the respective connecting pieces and the corresponding second through holes 320 are connected by the fixing member 150, so that the auxiliary hoop 200 can be fitted on the tower 500.

[0057] Similarly, in other embodiments, the auxiliary hoop 200 can also be designed as a U-shaped clamp structure (not shown in the figure), and one connecting piece is extended from each end of the U-shaped clamp. The size of the annular part of the U-shaped clamp is designed to be the same as the size of the upper end of the tower 500, and the U-shaped clamp has a certain elasticity. In installation, the two ends of the U-shaped clamp are pulled apart to be clamped into the tower, and then the two ends of the U-shaped clamp are connected by a fixing member such as a screw, so that the main hoop of the U-shaped clamp structure can be fixed to the tower.

[0058] The second through hole of the fixed connecting rod 300 is fixed in the middle of the fifth connecting plate and the seventh connecting plate of the secondary hoop 200 by the fixing member 150, wherein the fifth connecting plate and the seventh connecting plate are respectively located above the first connecting plate 111 and the second connecting plate 112 of the primary hoop 100. In this way, the various components of the primary hoop 100 and the secondary hoop 200 are parallel to each other, and the fixed connecting rod 300 is installed and at the same time perpendicular to the primary hoop 100 and the secondary hoop 200, so as to form a stable structure, thereby achieving the purpose of fixing the optical cable.

[0059] In this embodiment, the fixing member 150 can be a screw and its nut. When installing, the screw is passed through the first connecting hole 140 on the first connecting plate 111, one of the plurality of first through holes 310, the first connecting hole 140 on the second connecting plate 112, and then the nut is tightened to fix and install the lower end of the fixed connecting rod 300 to the primary hoop 100. When the connecting plates of the primary hoop are connected by the fixing member 150, they can be fixed to the tower.

[0060] The outer side of the first hoop plate 110 and the second hoop plate 120 of the primary hoop 100 is provided with a protruding first fixed connecting rod insertion hole 130 for fixing the lower end of the fixed connecting rod 300. The lower end of each of the fixed connecting rods 300 is fixedly connected with a first fixed connecting rod insertion hole 130. The number of the first fixed connecting rod insertion holes 130 is set according to the need, for example, one or two first fixed connecting rod insertion holes 130 are provided on each hoop plate.

[0061] The outer side of the third hoop plate 210 and the fourth hoop plate 220 of the secondary hoop 200 is provided with a protruding second fixed connecting rod insertion hole, and the upper end of each of the fixed connecting rods 300 is fixedly connected with a second fixed connecting rod insertion hole. In this way, the two ends of the fixed connecting rod 300 are fixed to the first fixed connecting rod insertion hole and the second fixed connecting rod insertion hole respectively, so as to fixedly connect the primary hoop and the secondary hoop.

[0062] In the case where the primary hoop 100 is provided with the first fixed connecting rod insertion hole 130 and the secondary hoop 200 is provided with the second fixed connecting rod insertion hole, the primary hoop 100 and the secondary hoop 200 can be connected only through the first fixed connecting rod insertion hole 130 and the second fixed connecting rod insertion hole 300, or can be connected only by fixing the fixed connecting rod 300 on the two connecting plates by the fixing member 150, or can be connected by both of the above two ways. In addition, if the intervals between the first fixed insertion hole, the first connecting plate and the second connecting plate are consistent, the upper end of the fixed connecting rod can be fixed in the second fixed connecting rod insertion hole, and the lower end of the fixed connecting rod can be fixed between the first connecting plate and the third connecting plate. In this way, the installation can be more convenient.

[0063] It can be understood that the main hoop 100 and the auxiliary hoop 200 can be connected by two or more fixed connecting rods 300, for example, two fixed connecting rods 300 are used to fix two opposite positions of the main hoop 100 and the auxiliary hoop 200, and for example, four fixed connecting rods 300 are used to fix four positions of the main hoop 100 and the auxiliary hoop 200.

[0064] During installation, after the auxiliary hoop 200 is fixedly connected with the upper end of the fixed connecting rod 300, the hoop lifting mechanism 400 is sleeved into the lower end of the fixed connecting rod 300, and the hoop lifting mechanism 400 is rotated. The rotation of the internal screw rod in the hoop lifting mechanism 400 can drive the fixed connecting rod 300 to rise, so that the auxiliary hoop 200 is lifted upward by the hoop lifting mechanism 400. When the auxiliary hoop 200 is lifted to the specified position, the hoop lifting mechanism 400 is removed, and the lower end of the fixed connecting rod 300 is fixed to the main hoop 100. Generally, the auxiliary hoop 200 is lifted above the optical cable 700 to be fixed, so that the optical cable 700 can be better fixed, so that the optical cable 700 is not easily hung off by the engineering vehicle, and is not easily pressed down or even broken by natural factors such as icing, snow and the like.

[0065] In the embodiment, the total length of the fixed connecting rod 300 can be set as needed, for example, 50 cm, 80 cm, 100 cm, etc. The internal screw rod of the hoop lifting mechanism 400 is spiral-shaped, one end of the internal screw rod is fixed on a manually operated wire pulling rod, and the other end abuts and is sleeved into the fixed connecting rod 300 in the hoop lifting mechanism 400. Thus, the operator rotates the wire pulling rod to make the internal screw rod lift upward, and the internal screw rod drives the abutting fixed connecting rod 300 to rise, so that the auxiliary hoop 200 gradually slides upward until reaching the specified position.

[0066] Under the action of the hoop lifting mechanism 400, the operator does not need to laboriously lift the auxiliary hoop, and can work at a position far away from the high-voltage line, thereby reducing the work burden and improving the safety of the work.

[0067] In addition, since the hoop lifting mechanism 400 is a tool and can be repeatedly used, the cost performance of the hoop lifting mechanism 400 is also high. It can be understood that the material of the hoop lifting mechanism 400 is metal, so that the lifting task can be completed during the work process, and the hoop lifting mechanism 400 will not be deformed during use, thereby being repeatedly used.

[0068] Continuing to refer to Figure 1 The auxiliary hoop 200 includes a third hoop piece 210 and a fourth hoop piece 220, a sixth connecting piece outwardly folded from the third hoop piece 210, and a seventh connecting piece outwardly folded from the fourth hoop piece 220 are provided with a second connecting hole 240 for connecting with the optical cable fixing device 600.

[0069] One end of the optical cable fixing device 600 is used to clamp the optical cable 700 to be fixed, and the other end is fixed to the second connecting hole 240 of the third or fourth clamp sheet 210 or 220, so that the optical cable 700 can be stably fixed, and the optical cable 700 cannot be easily hung off by the engineering machinery.

[0070] The fixed connecting rod 300 is made of insulating material. During the process of lifting the fixed connecting rod 300 upward by the clamp lifting mechanism 400, the fixed connecting rod 300 gradually approaches the high-voltage line, and thus there is a risk of electric shock and short circuit. The fixed connecting rod 300 made of insulating material prevents the occurrence of power accidents and ensures the safety of the workers.

[0071] The main clamp 100 and the auxiliary clamp 200 are made of metal material. The main clamp 100 and the auxiliary clamp 200 need to be fixed on the tower 500, and the tower 500 is generally made of reinforced concrete. Therefore, the main clamp 100 and the auxiliary clamp 200 made of metal material can be stably fixed on the tower 500 and are not easily corroded by natural factors such as wind, sun and rain. In the embodiment, the metal material can be iron, stainless steel, etc.

[0072] The optical cable fixing device provided in the embodiment comprises a main clamp, the main clamp is in a circular arc shape and is fixedly installed on a tower; an auxiliary clamp is arranged directly above the main clamp, the auxiliary clamp is connected with the main clamp through a plurality of fixed connecting rods; the upper end of the fixed connecting rod is fixed to the auxiliary clamp, and after the auxiliary clamp is lifted to a specified position by a clamp lifting mechanism, the lower end of the fixed connecting rod is fixed to the main clamp. By lifting the fixed connecting rod and the auxiliary clamp through the clamp lifting mechanism, the auxiliary clamp can be lifted to the specified position, and the workers can be prevented from working in the vicinity of the high-voltage line, so that the optical cable can be fixed to a higher position and the personal safety is ensured.

[0073] The application further provides an optical cable fixing method, the method is applied to an optical cable fixing device, Figure 5 The optical cable fixing method provided in another embodiment of the application is shown in a flowchart, as shown in Figure 5 The method comprises the following steps:

[0074] In step S101, a main clamp and an auxiliary clamp are fixedly installed on a tower, the auxiliary clamp is connected through a fixed connecting rod, and after the auxiliary clamp is lifted to a specified position by a clamp lifting mechanism, the lower end of the fixed connecting rod is fixed to the main clamp.

[0075] The main hoop is fixedly installed on the tower, and the secondary hoop is installed above the main hoop; the first hoop piece and the second hoop piece of the main hoop are wrapped around the tower, and the third hoop piece and the fourth hoop piece of the secondary hoop are correspondingly installed above the first hoop piece and the second hoop piece. The upper end of the fixed connecting rod is fixedly connected with the secondary hoop, and the fixed connecting rod is sleeved into the hoop lifting mechanism; the third hoop piece includes a fifth connecting piece and a sixth connecting piece, and the fourth hoop piece includes a seventh connecting piece and an eighth connecting piece; the fifth connecting piece, the sixth connecting piece, the seventh connecting piece and the eighth connecting piece are provided with connecting holes. The second through hole of the upper end of the fixed connecting rod is aligned with the connecting holes of the fifth connecting piece and the seventh connecting piece to form a through hole through which the fixing member can pass, and after the fixing member is tightened, the secondary hoop and the fixed connecting rod are stably connected. Generally, 2-4 fixed connecting rods are installed.

[0076] The fixed connecting rod is driven upward by the hoop lifting mechanism, so that the fixed connecting rod drives the secondary hoop to slide upward; the internal screw rod of the hoop lifting mechanism is spiral, one end of the internal screw rod is fixed on the manually operated wire pulling rod, and the other end abuts against the fixed connecting rod sleeved into the hoop lifting mechanism. Thus, the operator rotates the wire pulling rod to drive the internal screw rod to lift upward, the internal screw rod drives the abutting fixed connecting rod to rise, so that the secondary hoop gradually slides upward until reaching the specified position. In this way, the operator only needs to operate the hoop lifting mechanism to lift the secondary hoop upward, and does not need to operate close to the high-voltage line, greatly improving personal safety.

[0077] When the secondary hoop reaches the specified position, the hoop lifting mechanism is taken out, and the lower end of the fixed connecting rod is fixed to the main hoop.

[0078] Step S102: The optical cable fixing device is clamped on the optical cable to be fixed, and the upper connecting part of the optical cable fixing device is connected with the connecting hole reserved in the secondary hoop, so that the optical cable is fixed on the optical cable fixing device.
