Description

Technical Field

[0001] The present invention relates to the technical field of power transmission lines, and in particular to a cable clamp. Background Art

[0002] After the cable is laid, it is necessary to use cable clamps to fix the cables on the bracket. For high-voltage cables, due to their single-core structure, two types of fixing clamps are usually used. One is to fix the single-core cable with a single clamp, and the other is to fix the three-core cable with one clamp.

[0003] Through the study of high-voltage cable lines in environments such as bridges, it was found that for single-core cables fixed with a single clamp, due to the small contact area between the cable and the existing clamp, the mechanical stress on the structural layer of the cable in contact with the clamp will be too concentrated under the action of mechanical vibration, causing deformation of the cable structure and even cable line failure. Summary of the invention

[0004] In view of this, the present invention proposes a cable clamp, which aims to solve the problem that the mechanical stress on the structural layer of the cable is too concentrated due to the small contact area between the existing clamp and the cable, causing the cable structure to deform and even cause cable line failure.

[0005] The present invention proposes a cable clamp, which includes: an upper arc clamp and a lower arc clamp; wherein the upper arc clamp is relatively arranged above the lower arc clamp at the longitudinal middle position of the lower arc clamp, and a cable storage channel is formed between the upper arc clamp and the lower arc clamp, which is used to support the cable and provide a fixing point; the lower arc clamp has a saddle-shaped structure in the longitudinal direction, which is used to provide arc-shaped support for the cable.

[0006] Furthermore, in the above-mentioned cable clamp, the lower arc-shaped clamp comprises: a fixed section and two arc-shaped sections; wherein the fixed section is adapted to the upper arc-shaped clamp, and the fixed section and the upper arc-shaped clamp are arranged to form a circular channel to provide a support fixing point; the two arc-shaped sections are respectively arranged on both sides of the fixed section, for adapting to the hooking arc of the cable bent under the action of gravity, so as to respectively support the two sides of the cable fixing point.

[0007] Furthermore, in the above-mentioned cable clamp, a weight-adding block is provided on the arc segment for adding weight to the arc segment to increase the downward curvature of the arc segment.

[0008] Furthermore, in the above-mentioned cable clamp, the weight-increasing block is adjustably connected to the outer wall of the arc segment along the length direction of the arc segment, so as to adjust the downward curvature of the arc segment.

[0009] Furthermore, in the above-mentioned cable clamp, the centers of the two arc segments are both arranged below the fixed segment, and the two arc segments are arranged opposite to each other.

[0010] Furthermore, in the above-mentioned cable clamp, a vibration detection sensor is provided on the upper arc clamp for contacting the cable to measure the mechanical vibration amount of the cable.

[0011] Furthermore, in the above-mentioned cable clamp, a vibration collection unit is provided on the outer wall of the upper arc-shaped clamp, which is electrically connected to the vibration detection sensor and is used to receive the mechanical vibration amount measured by the vibration detection sensor.

[0012] Furthermore, in the above-mentioned cable clamp, a measuring hole penetrating the upper arc-shaped clamp is provided at a lateral middle position of the upper arc-shaped clamp, and the vibration detection sensor is arranged in the measuring hole or penetrates the measuring hole.

[0013] Furthermore, in the above-mentioned cable clamp, a lower supporting portion is provided on the outer periphery of the lower arc-shaped clamp just below the upper arc-shaped clamp for supporting the lower arc-shaped clamp.

[0014] Furthermore, in the above-mentioned cable clamp, the connecting parts on both sides of the upper arc-shaped clamp and the lower arc-shaped clamp are detachably connected by fasteners.

[0015] The cable clamp provided by the present invention has an upper arc clamp relatively arranged above the lower arc clamp at the longitudinal middle position of the lower arc clamp, and a cable storage channel is formed between the upper arc clamp and the lower arc clamp for supporting the cable and providing a fixing point; the cable is supported in an arc shape by the lower arc clamp, so as to reduce the stress concentration borne by the cable structure layer under the action of vibration. Compared with the prior art, the lengths of the upper and lower clamps are relatively short, and only fixed support points of the cable are provided, so that the two sides of the cable fixed in the clamp bend or even sag under the action of gravity, that is, an angle or even a right angle appears between the part of the cable in the clamp and the part outside the clamp, resulting in excessive stress concentration at the end of the cable at the lower clamp, so that deformation occurs and even cable line failure occurs. In particular, due to the long-term mechanical vibration in the bridge and subway passage acting on the cable line, the vibration caused by the external mechanical vibration on the cable and the clamp is not synchronized, so that there is a certain degree of impact and friction between the cable and the clamp, and the structure at the bottom of the clamp is also subjected to the self-gravity of the cable. This will cause stress concentration at the position where the cable contacts the clamp, especially at the bottom end of the clamp, which will further cause deformation or even damage to the cable outer sheath and other structural layers. In this embodiment, the cable is supported in an arc shape by a lower arc clamp with a saddle-shaped structure to increase the support area and buffer the curvature of the cable. Even if the cable sags, the angle between the upper part of the lower arc clamp and the outer part of the lower arc clamp can be increased, thereby reducing the stress concentration of the cable, especially reducing the stress concentration borne by the cable structural layer under the action of vibration, reducing the damage to the cable structure due to mechanical vibration, improving the reliability of cable line operation, and avoiding direct and indirect economic losses caused by power outages due to faults.

[0016] Furthermore, a vibration detection sensor is provided on the upper arc-shaped clamp to measure the mechanical vibration of the cable. Compared with the prior art, the monitoring and analysis of the mechanical vibration characteristics of the cable in environments such as bridges is necessary for carrying out the evaluation of the cable operation status. Usually, optical fiber or acceleration sensors are arranged on the cable to measure the vibration distributed form or point vibration measurement. The distributed form can achieve full-length coverage but cannot achieve accurate measurement of certain points. Although point vibration measurement can achieve accurate measurement of certain points, the economy and arrangement method on the cable structure layer need to be improved. At the same time, the long-term reliability will also be attenuated due to the continuous action of the vibration. In this embodiment, the vibration detection sensor is arranged on the upper arc-shaped clamp, which realizes Accurate quasi-distributed measurement, on the other hand, maintains close contact with the cable, so as to measure more accurately. At the same time, since the external mechanical vibration is mostly transmitted from the bracket to the cable through the clamp, a more accurate measurement of the vibration is achieved. That is, it is necessary to carry out measurement and analysis of vibration characteristic quantities for cable lines in vibration environments such as bridges and subways. It solves the contradiction between full-length optical fiber distributed measurement and accurate measurement of additional sensors, and realizes quasi-distributed measurement of mechanical vibration characteristic values ​​of cable lines in bridges and subway passages. It can replace the existing distributed optical fiber and the method of installing acceleration sensors, saving economic investment while avoiding the secondary installation and construction of sensors, and also more accurately measuring the vibration quantity.

[0025] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein.

It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to improve the operational reliability of cable lines in vibration environments such as bridges and subways, and reduce operational failures caused by cable structural damage caused by mechanical vibration, starting from the construction and layout characteristics of cable lines and the characteristics of the effects of mechanical vibration on cables, and taking cable clamps as the entry point, the structure of the cable clamps is improved to reduce the stress concentration of mechanical vibration on the cables near the cable clamps.

[0027] See also Figures 1 to 4 , which shows the preferred structure of the cable clamp provided by the embodiment of the present invention. As shown in the figure, the cable clamp includes: an upper arc clamp 1, a lower arc clamp 2, a fastener 3, a vibration detection sensor 4 and a vibration collection unit 5; wherein,

[0028] like Figure 1 As shown, the upper arc clamp 1 is relatively arranged above the lower arc clamp 2 at the longitudinal middle position of the lower arc clamp 2, and a cable storage channel 6 is formed between the upper arc clamp 1 and the lower arc clamp 2 to support and provide a fixing point for the cable (not shown in the figure). Specifically, the upper arc clamp 1 and the lower arc clamp 2 can be relatively arranged so that the upper arc clamp 1 and the lower arc clamp 2 are surrounded by a hollow cylindrical structure with openings at both ends, that is, as a cable storage channel 6, to support and provide a fixing point for the cable. In this embodiment, the length direction of the lower arc clamp 2 (such as Figure 1 The arc direction shown in the figure is the longitudinal direction, and the width direction of the arc hoop 2 is the transverse direction.

[0029] Continue to see Figure 1, the longitudinal length of the lower arc-shaped clamp 2 is a saddle-shaped structure, which is used to provide arc-shaped support for the cable. Specifically, the longitudinal length of the lower arc-shaped clamp 2 can refer to the transverse structure of the saddle-shaped structure, that is, it is an arched structure, so as to support the cable through the arc structures on both sides. In this embodiment, the lower arc-shaped clamp 2 is lengthened in combination with the bending of the cable and is a saddle-shaped structure with a certain curvature, wherein the lower arc-shaped clamp 2 can be 300mm, which is 500% longer than the 60mm length of the bottom of the existing general clamp, greatly increasing the contact area between the clamp and the cable, and, because the cable has a certain curvature at the fixed position, the lower arc-shaped clamp 2 can be a saddle-shaped structure with a certain curvature.

[0030] Continue to see Figure 1 To ensure the support stability of the lower arc hoop 2, preferably, the outer periphery of the lower arc hoop 1 is provided with a lower support portion 7 just below the upper arc hoop 2, for supporting the lower arc hoop 2. Specifically, the lower support portion 7 may be an arc-shaped structure, and its outer contour may refer to the lower arc hoop 2. The lower support portion 7 may be connected to the lower arc hoop 2 by fasteners. Of course, the lower support portion 7 may be connected to the connection between the lower arc hoop 2 and the upper arc hoop 1, so as to facilitate the synchronous disassembly and assembly of the three.

[0031] like Figure 3 and Figure 4 As shown, the connection between the upper arc hoop 1 and the lower arc hoop 2 (as shown in FIG. Figure 3 The left and right connections shown in the figure) can be detachably connected by fasteners 3, so as to facilitate the replacement of parts, etc., and also to facilitate the placement of cables; of course, the upper arc clamp 1 and the lower arc clamp 2 can also be set to be hinged at one end and detachably connected at the other end, or other connection methods can be used, which is not limited in this embodiment; the cross-sectional shape of the upper arc clamp 1 and the lower arc clamp 2 can be a semicircular ring, of course, it can be other various arcs. It should be noted that the upper arc clamp 1 and the lower arc clamp 2 are relatively arranged and connected to form a hollow cylinder, and the cross-sectional shape is not limited in this embodiment. In this embodiment, the two side connections of the upper arc clamp 1 and the lower arc clamp 2 can be detachably connected by fasteners 3, and at the same time, the lower support part 7 is also fixed to the lower arc clamp 2 by the fasteners 3. In this embodiment, the fastener 3 can be a bolt. Among them, the lower support part 7 can be a rigid structure.

[0032] Continue to see Figure 3 and Figure 4, a vibration detection sensor 4 is provided on the upper arc clamp 1, which is used to contact the cable to measure the mechanical vibration of the cable, so as to realize the monitoring of the vibration characteristic value of the cable line. Specifically, the vibration detection sensor 4 can be fixed on the upper arc clamp 1, and in particular, can be set on the top of the upper arc clamp 1. The vibration detection sensor 4 contacts the outer wall of the cable, measures the mechanical vibration of the cable, and transmits the collected mechanical vibration to the vibration collection unit 5. After receiving the mechanical vibration, the vibration collection unit 5 can display or process the mechanical vibration. Among them, the vibration detection sensor 4 can be an acceleration sensor. In the prior art, the monitoring and analysis of the mechanical vibration characteristic of the cable in the environment of bridges and the like is necessary to carry out the evaluation of the cable operation status. Usually, optical fiber or acceleration sensor is arranged on the cable to measure the vibration. In this embodiment, the vibration detection sensor 4 is arranged on the upper arc clamp 1, so that it is necessary to carry out the measurement and analysis of the vibration characteristic for the cable line in the vibration environment of bridges, subways, etc., which solves the contradiction between the full-length optical fiber distributed measurement and the accurate measurement of the additional sensor.

[0033] Continue to see Figure 3 and Figure 4 A vibration collection unit 5 is provided on the outer wall of the upper arc-shaped clamp 1, which is electrically connected to the vibration detection sensor 4 and is used to receive the mechanical vibration measured by the vibration detection sensor 4. In this embodiment, the vibration collection unit 5 may include a collection module, a power supply module and a display module, wherein the collection module is connected to the vibration detection sensor 4 and is used to receive the mechanical vibration measured by the vibration detection sensor 4; the display module is connected to the collection module and is used to display the mechanical vibration; the power supply module is connected to the collection module and the display module respectively. Figure 5 As shown, the vibration collection unit 5 can be connected to the vibration detection sensor 4 through a data line 9 or other connecting lines to transmit data, and the collection module can be connected to the vibration detection sensor 4 through a data line 9 or other connecting lines. Specifically, the vibration collection unit 5 is also arranged on the side wall of the upper arc-shaped clamp 1, and is arranged side by side with the vibration detection sensor 4. At the same time, the vibration collection unit 5 can also include a shell, and the collection module, the power supply module and the display module are all arranged in the shell. The display module is a display screen, preferably a liquid crystal display screen; the power supply module is preferably a lithium battery. The vibration collection unit 5 also includes a switch, which is arranged in the shell, and can be specifically arranged on the connecting line between the power supply module and the collection module and the display module. The switch is used to control the opening and closing of the vibration collection unit 5.

[0034] In this embodiment, the clamp may also be provided with an alarm (not shown in the figure), which is connected to the vibration collection unit 5. When the data collected by the vibration collection unit 5 exceeds the preset mechanical vibration threshold, an alarm message is output to give an alarm. Specifically, the alarm may be a sounder or a light-emitting unit, which may give an alarm through sound and / or light. It can be seen that by setting an alarm, the mechanical vibration of the cable can be warned in real time, thereby improving the safety of line operation.

[0035] Continue to see Figure 1 A measuring hole 11 penetrating the upper arc-shaped clamp 1 is provided at the middle position of the upper arc-shaped clamp 1, and a vibration detection sensor 4 is arranged in the measuring hole 11 or penetrates the measuring hole 11, so that the vibration detection sensor 4 can contact the cable to achieve the measurement of the mechanical vibration. Figure 5 As shown, the vibration detection sensor 4 is arranged in the horizontal direction (such as Figure 5 The left and right sides of the upper arc-shaped hoop 1 may be respectively provided with four fixing holes 12 to achieve fixation between the upper arc-shaped hoop 1 and the lower arc-shaped hoop 2 through the fastener 3.

[0036] Continue to see Figure 1 and Figure 2 The lower arc-shaped hoop 2 includes: a fixed section 21 and two arc sections 22; wherein the fixed section 21 is adapted to the upper arc-shaped hoop 1, and the fixed section 21 and the upper arc-shaped hoop 1 are surrounded to form a circular channel to provide a support fixing point; the two arc sections 22 are respectively arranged on both sides of the fixed section 21 (such as Figure 1 The two arc segments 22 are respectively arranged on both sides of the fixing section 21, so that the lower arc clamp 2 is combined to form a saddle-shaped structure. In this embodiment, the centers of the two arc segments 22 are both arranged below the fixing section 21, and the two arc segments 22 are arranged opposite to each other, that is, they are both bent downward, so that they are adapted to the bending of the cable, thereby avoiding stress concentration of the cable.

[0037] In this embodiment, in order to further improve the compatibility between the arc segment 22 and the curvature of the cable, preferably, a weight-adding block is provided on the arc segment 22 for adding weight to the arc segment 22, so as to increase the downward curvature of the arc segment 22 and improve the compatibility between its curvature and the curvature of the cable; further preferably, the weight-adding block is adjustably connected to the outer wall of the arc segment 22 along the length direction of the arc segment 22, so as to adjust the downward curvature of the arc segment 22 and further improve the compatibility between the downward curvature of the arc segment 22 and the curvature of the cable.

[0038] like Figure 4As shown, a support plate 8 may be provided on the outer wall of the upper arc-shaped clamp 1 and the fixing section 21 for supporting and fixing.

[0039] The cable clamp can be a core cable clamp or a multi-core cable clamp.

[0040] In summary, in the cable clamp provided in this embodiment, the upper arc clamp 1 is relatively arranged above the lower arc clamp 2 at the longitudinal middle position of the lower arc clamp 2, and a cable storage channel 6 is formed between the upper arc clamp 1 and the lower arc clamp 2, which is used to support the cable (not shown in the figure) and provide a fixing point; the cable is supported in an arc shape by the lower arc clamp 2 to reduce the stress concentration on the cable structure layer under the action of vibration. Compared with the prior art, the lengths of the upper and lower clamps are relatively short, and only fixed support points of the cable are provided, so that the two sides of the cable fixed in the clamp bend or even sag under the action of gravity, that is, an angle or even a right angle appears between the portion of the cable in the clamp and the portion outside the clamp, resulting in excessive concentration of stress at the end of the cable at the lower clamp, causing deformation and even cable line failure. In particular, due to the long-term mechanical vibration in bridges and subway passages acting on the cable line, the vibration caused by external mechanical vibration on the cable and the clamp is not synchronized, so that there is a certain degree of impact and friction between the cable and the clamp, and the structure at the bottom of the clamp is also subjected to the cable's own gravity. This will cause stress concentration at the position where the cable contacts the clamp, especially at the bottom end of the clamp, which will further cause deformation or even damage to the cable outer sheath and other structural layers. In this embodiment, the cable is supported in an arc shape by the lower arc clamp 2 with a saddle-shaped structure to increase the support area and buffer the curvature of the cable. Even if the cable sags, the angle between the upper part of the lower arc clamp 2 and the outer part of the lower arc clamp 2 can be increased, thereby reducing the stress concentration of the cable, especially reducing the stress concentration borne by the cable structural layer under the action of vibration, reducing the damage to the cable structure due to mechanical vibration, improving the reliability of cable line operation, and avoiding direct and indirect economic losses caused by power outages due to faults.

[0041] Furthermore, a vibration detection sensor 4 is provided on the upper arc clamp 1 to measure the mechanical vibration of the cable. Compared with the prior art, the monitoring and analysis of the mechanical vibration characteristics of the cable in an environment such as a bridge is necessary for carrying out the evaluation of the cable operation status. Usually, optical fiber or acceleration sensors are arranged on the cable to measure the vibration, and distributed form or point vibration measurement is used. The distributed form can achieve full-length coverage but cannot achieve accurate measurement of certain points. Although point vibration measurement can achieve accurate measurement of certain points, the economy and arrangement method on the cable structure layer need to be improved. At the same time, the long-term reliability will also be attenuated due to the continuous action of the vibration. In this embodiment, the vibration detection sensor 4 is arranged on the upper arc clamp 1. On the one hand, it is On the one hand, accurate quasi-distributed measurement is achieved, and on the other hand, close contact with the cable is maintained, so as to measure more accurately. At the same time, since the external mechanical vibration is mostly transmitted from the bracket to the cable through the clamp, a more accurate measurement of the vibration is achieved. That is, it is necessary to carry out measurement and analysis of vibration characteristic quantities for cable lines in vibration environments such as bridges and subways. The contradiction between full-length optical fiber distributed measurement and accurate measurement of additional sensors is solved, and quasi-distributed measurement of mechanical vibration characteristic values ​​of cable lines in bridges and subway passages is also achieved. It can replace the existing distributed optical fiber and the method of installing acceleration sensors, saving economic investment while avoiding the secondary installation and construction of sensors, and also more accurately measuring the vibration quantity.
