[0002] There are many cables in the cable trench of a thermal power plant. The power cable sheath and cable accessories are the parts of the cable line with relatively weak insulation structure and prone to operation failures. During the manufacturing, installation, operation and maintenance of power cables, problems such as product quality, overload operation and external force damage will inevitably occur, which may lead to operation failures of the cable itself.

DETAILED DESCRIPTION

[0022] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0023] In the present disclosure, unless otherwise specified, the directional words "inside" and "outside" used refer to the "inside" and "outside" relative to the contour of the corresponding component itself. In addition, the use of words such as "first" and "second" is intended to distinguish different components and does not have order and importance. In addition, when referring to the drawings in the following description, the same symbols in different drawings represent the same elements. It should be understood by those skilled in the art that the above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0024] According to the specific implementation of the present disclosure, Figure 1 and Figure 2 As shown, a temperature detection device for a cable trench is provided, which includes: a mounting structure 1, a driving structure 2 and a plurality of temperature sensors 3. The driving structure 2 is arranged on the mounting structure 1, and includes a driving member 21 and a transmission member 23 which is transmission-connected to the driving member 21. The plurality of temperature sensors 3 are sequentially connected to the transmission member 23 at intervals along a preset direction. The driving member 21 can drive the temperature sensor 3 to move along the preset direction through the transmission member 23.

[0025] Through the above technical scheme, when the temperature detection device of the present invention is used to detect the temperature of the cable in the cable trench, the installation structure 1 can be set in the cable trench, and the preset direction can be arranged to be consistent with the direction of the cable. Here, the driving member 21 drives the transmission member 23 to move, which can drive multiple temperature sensors 3 arranged at intervals on the transmission member 23 to move along the extension direction of the cable at the same time. In this way, the temperature sensor 3 can collect the temperature of the portion of the cable between the two temperature sensors 3 through its own movement. Therefore, through the movement of each temperature sensor 3, all-round detection of the cable temperature can be achieved. In addition, through the movement of each temperature sensor 3, the present invention can also reduce the number of temperature sensors 3 arranged in the cable trench.

[0026] In some embodiments of the present disclosure, reference Figure 1 As shown, the mounting structure 1 includes two mounting frames 11 spaced apart in a preset direction, the driving structure 2 includes a transmission wheel 22 rotatably connected to each mounting frame 11, the transmission member 23 can be constructed as a transmission rope, the transmission rope is wound between the two transmission wheels 22, and the driving member 21 is in transmission connection with any one of the transmission wheels 22. In this way, the two mounting frames 11 can be respectively mounted on both sides of the extension direction of the cable trench, wherein the mounting frames 11 can provide a mounting base for the transmission wheel 22, and the transmission wheel 22 can be driven to rotate by the driving member 21, which can drive the transmission rope to rotate around the two transmission wheels 22, thereby driving the temperature sensor 3 connected to the transmission rope to move, and the structure is simple and easy to be arranged in the cable trench.

[0027] In other embodiments, the transmission member 23 may also be constructed as a gear and a rack, wherein the rack extends in a preset direction, and the gear is driven to rotate by the driving member 21 to drive the rack to move in the preset direction, thereby driving the temperature sensor 3 to move. At this time, the temperature sensor 3 may be connected to the rack.

[0028] In some embodiments of the present disclosure, reference Figure 1 As shown, the temperature detection device may include a camera 4, and the camera 4 may be connected to the transmission member 23. In this way, the camera 4 can follow the transmission member 23 to move in a preset direction. When the temperature sensor 3 detects that the cable temperature is abnormal, the transmission member 23 can drive the camera 4 to move to the abnormal position of the cable and take images of the abnormal position of the cable, so as to collect live images of the abnormal position of the cable. And by setting the camera 4 on the transmission member 23, the movement of the camera 4 can be used to expand the shooting range of the camera 4, and the number of cameras 4 set in the cable trench can be reduced. In addition, when the transmission member 23 is constructed as a transmission rope, the camera 4 is connected to the transmission rope and moves between the two mounting frames 11 with the transmission rope.

[0029] In some embodiments, the mounting frame 11 is connected to a controller 6, and the controller 6 is electrically connected to the multiple temperature sensors 3, the camera 4, and the driving member 21, so that the controller 6 can control the driving member 21 to drive the transmission member 23, so that the multiple temperature sensors 3 are periodically reciprocated between the two mounting frames 11, so as to achieve all-round temperature detection of the cables in the cable trench. At the same time, the controller 6 can simultaneously collect information from multiple temperature sensors 3. When the temperature sensor 3 at the corresponding position receives abnormal temperature information, the controller 6 can control the driving member 21 to drive the camera 4 to move to the abnormal point to collect images and transmit the collected images to the external terminal.

[0030] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown, the temperature detection device may include a plurality of connection structures 5 arranged at intervals along a preset direction, the connection structure 5 includes a connection seat 51 and a push-up member 52, the connection seat 51 is connected to the temperature sensor 3, the connection seat 51 has a first through groove 511 and a connection hole 512 that are interconnected and perpendicular to each other, the transmission rope is passed through the first through groove 511, and the push-up member 52 is connected to the connection hole 512 and pushes against the transmission rope. Here, the central axis of the first through groove 511 can be perpendicular to the central axis of the connection hole 512, so that the push-up member 52 can pass through the connection hole 512 and push against the transmission rope. In this way, when the transmission rope is moving, the friction between the push-up member 52 and the transmission rope can be used to achieve relative stillness of the transmission rope and the push-up member 52, thereby achieving relative stillness of the temperature sensor 3 on the connection seat 51 and the transmission rope, thereby, the transmission rope can drive the temperature sensor 3 to move along the preset direction. When the connecting seat 51 moves to abut against the mounting frame 11, the transmission rope continues to move. When the transmission rope overcomes the friction between the transmission rope and the abutment 52, the transmission rope can move relative to the connecting seat 51. In this way, the transmission rope can continue to drive the camera 4 to move. Therefore, such a setting can take into account the movement range of the camera 4 and the movement of the temperature sensor 3, thereby avoiding the connection structure 5 limiting the movement range of the camera 4.

[0031] In other embodiments, reference Figure 1 and Figure 2As shown, the transmission rope can be inserted into the first through groove 511, and the diameter of the transmission rope can be larger than the diameter of the first through groove 511, so as to have a certain friction force with the groove wall of the first through groove 511. In this way, the friction between the groove wall of the first through groove 511 and the transmission rope can realize the relative stillness of the transmission rope and the connecting seat 51, thereby realizing the relative stillness of the temperature sensor 3 on the connecting seat 51 and the transmission rope. Therefore, the transmission rope can drive the temperature sensor 3 to move along the preset direction. When the connecting seat 51 moves to abut against the mounting frame 11, the transmission rope continues to move. When the transmission rope overcomes the friction between the groove wall of the first through groove 511, the transmission rope can move relative to the connecting seat 51. In this way, the transmission rope can continue to drive the camera 4 to move. In other embodiments of the present disclosure, other connection structures 5 with friction force can be set between the transmission rope and the connecting seat 51, or other connection structures 5 that can drive the temperature sensor 3 to move while avoiding limiting the moving range of the camera 4. The present disclosure does not make specific restrictions on this.

[0032] In some embodiments of the present disclosure, the connection hole 512 can be configured as a threaded hole, and the push-up member 52 can be configured as a screw, which is threadedly connected to the threaded hole. In this way, the push-up member 52 can be connected to the connection hole 512, and the push-up member 52 can be screwed relative to the connection hole 512 to adjust the degree of pressure of the push-up member 52 on the transmission rope, thereby adjusting the friction between the push-up member 52 and the transmission rope.

[0033] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown, an elastic member 53 may be provided between the abutting member 52 and the transmission rope, and the abutting member 52 abuts the elastic member 53 against the transmission rope. In this way, when the abutting member 52 abuts against the transmission rope through the elastic member 53, the elastic member 53 can always abut against the transmission rope under the action of elastic force, thereby preventing the abutting member 52 from loosening, thereby reducing the friction between the abutting member 52 and the transmission rope, and ensuring that when the connecting seat 51 is spaced from the mounting frame 11, the transmission rope can stably drive the temperature sensor 3 to move.

[0034] In some embodiments of the present disclosure, reference Figure 1 As shown, a guide rod 12 may be connected between the two mounting brackets 11, the guide rod 12 extends along a preset direction, and the guide rod 12 is inserted into the second through slot 513 of the connecting seat 51. In this way, the guide rod 12 can guide the movement of the connecting seat 51, thereby improving the stability of the temperature sensor 3 when moving.

[0035] In some embodiments of the present disclosure, reference Figure 1As shown, the camera 4 can be arranged between any two temperature sensors 3. In this way, compared with arranging the camera 4 outside any two temperature sensors 3, the maximum displacement distance of the camera 4 can be shortened, so that the camera 4 can quickly reach the preset position.

[0036] In some embodiments of the present disclosure, reference Figure 1 As shown, the camera 4 can be provided with an equal number of temperature sensors 3 on both sides of the preset direction. In this way, the maximum displacement distance of the camera 4 can be further shortened, the image acquisition speed of the camera 4 can be improved when the cable is abnormal, and the number of cameras 4 required to be set can be reduced.

[0037] In some embodiments of the present disclosure, reference Figure 1 As shown, the driving structure 2 may include a meshing worm wheel and a worm, the worm wheel is in driving connection with the driving member 21, and the worm is in driving connection with the transmission wheel 22 on the same side. In this way, the worm wheel is driven to rotate by the driving member 21, which can drive the worm meshing with the worm wheel to rotate, thereby driving the transmission wheel 22 to rotate, so as to drive the transmission rope wound around the transmission wheel 22 to move.

[0038] The driving member 21 may be configured as a driving motor, the rotating shaft of the driving motor being coaxially arranged with the worm gear to drive the worm gear to rotate, or the driving member 21 may be configured as other devices capable of driving the worm gear to rotate, and the present disclosure does not impose any specific limitation on this.

[0039] Below, reference Figure 1 and Figure 2As shown, the present disclosure will combine the above specific embodiments to introduce the specific use process of the temperature detection device for the cable trench in detail. When the temperature detection device of the present disclosure is used to detect the temperature of the cable in the cable trench, the two mounting frames 11 are respectively installed on the side wall of the cable trench along the extension direction of the cable, the extension direction of the guide rod 12 is consistent with the extension direction of the cable, the two mounting frames 11 are respectively installed with the transmission wheels 22 and the transmission rope wound between the transmission wheels 22, and the plurality of temperature sensors 3 are respectively installed on the connecting seat 51 in a one-to-one correspondence. The transmission rope is inserted into the first through groove 511 of the connecting seat 51, and the elastic member 53 is screwed to the transmission rope in the first through groove 511 by screwing the abutting member 52, and the relative stillness between the connecting seat 51 and the transmission rope is achieved through the static friction between the elastic member 53 and the transmission rope, thereby achieving the installation of the connecting seat 51, and the relative stillness of the temperature sensor 3 on the connecting seat 51 and the transmission rope, and the connecting seat 51 is slidably connected to the guide rod 12, so that the guide rod 12 guides the movement of the connecting seat 51 in the preset direction. The controller 6 is electrically connected to the driving member 21, so that the worm gear structure is driven by the driving member 21 to drive the transmission wheel 22 to rotate periodically, thereby driving the transmission rope wound between the two transmission wheels 22 to be able to move back and forth periodically between the two mounting frames 11, so as to detect the temperature of the cables at various locations. When the temperature sensor 3 detects that the temperature of the cable is abnormal, the temperature sensor 3 transmits a signal to the controller 6, and the controller 6 controls the camera 4 to move to the temperature abnormality and take images. When the temperature abnormality is near the ends of the two mounting frames 11, the driving member 21 drives the camera 4 to move toward the mounting frame 11 until the connecting seat 51 abuts against the mounting frame 11, and the driving member 21 continues to drive the transmission rope to move until the transmission rope overcomes the friction between the elastic member 53 and the transmission rope can move relative to the connecting seat 51, so that the transmission rope can continue to drive the camera 4 to move in the direction close to the mounting frame 11, thereby realizing the acquisition of images of the cables laid at various locations in the cable trench.
