It has the characteristics of dustproof and waterproof. During the use of closed cable trays, problems such as aging of some cables, long-term full load or frequent overload will cause the temperature of the internal cables to rise during operation, which will accelerate the aging of the cable insulation layer.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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.

[0033] Example 1: Reference Figure 1-Figure 10 This embodiment discloses a temperature intelligent monitoring device based on a closed cable tray, including a tray body 1, a plurality of temperature transfer structures, a hoisting mechanism and a driving mechanism for driving the hoisting mechanism to move, wherein the plurality of temperature transfer structures are linearly and equidistantly distributed in a plurality of cable trays. Figure 1 On the bridge body 1 shown in FIG. 1 , the temperature transfer structure is used to transfer the temperature of the cables in the bridge body 1. Figure 5 and Figure 7 As shown, the temperature transfer structure includes a positioning groove 11, a mounting block 12, an arc-shaped heat-conducting clamp block 13 and a heat-conducting rod 14. The positioning groove 11 is opened at the bottom of the bridge body 1, the mounting block 12 is inserted into the positioning groove 11, and the heat-conducting rod 14 is arranged on the mounting block 12. The bottom end of the heat-conducting rod 14 is located outside the bridge body 1, and the top end of the heat-conducting rod 14 is located inside the bridge body 1 and fixedly connected to the heat-conducting clamp block 13. A plurality of heat-conducting clamp blocks 13 clamp the cable body 15 to be monitored. Figure 1 The hoisting mechanism includes an L-shaped hanging rail 2, a hanger 21, a support wheel 22 rotatably connected to the hanger 21, and a hanging platform 3 with an inverted T-shaped structure. The hanging rail 2 and the hanger 21 are each provided with two and are respectively located on both sides of the bridge frame body 1. The hanging platform 3 is fixedly installed between the two hangers 21. Two support wheels 22 are provided on the same hanger 21 and are symmetrical to each other. The support wheel 22 is in contact with the hanging rail 2. A thermal imaging device 31 for obtaining image information of the temperature transfer structure is provided on one side of the hanging platform 3. The hoisting mechanism is driven to move by a driving mechanism, which manifests as a linear displacement of the entire hanging platform 3 along the length direction of the bridge frame body 1. An electronic tag is provided on the mounting block 12. In the present embodiment, the cable body 15 is clamped by the heat-conducting clamp 13, so that the heat on the cable body 15 is transferred to the heat-conducting rod 14 through the heat-conducting clamp 13. When used for the first time, it is carried out according to the standard plan, and the standard plan is repeated according to the subsequent monitoring effect, and the first control plan or the second control plan is implemented. The standard plan is to control the servo motor 35 to control the lifting mechanism according to the standard speed v to complete a complete detection path. The complete detection path is the end-to-end distance of the bridge body 1. The temperature information on the heat-conducting rod 14 is obtained by the thermal imaging device 31. Any temperature transfer structure is a monitoring point. In a complete detection path, when the temperatures of all monitoring points are normal, the standard plan is repeated from the nearest port, so as to facilitate real-time grasp of the temperature information of each monitoring point in the bridge body 1, prevent the temperature from being too high, and improve the effect of intelligent temperature monitoring.

[0034] In one example, if Figure 1 and Fig. 9As shown, the driving mechanism includes a driving wheel 32 arranged between the two supporting wheels 22, a first gear 33, a second gear 34 arranged on the hanger 21 and a servo motor 35. The driving wheel 32 and the first gear 33 are rotatably connected on both sides of the hanger 21 through a first shaft rod, the first gear 33 and the second gear 34 are meshed, and the second gears 34 on the two hangers 21 are connected by rotating the second shaft rod arranged on the hanging platform 3. The second shaft rod is driven by a driving motor fixedly installed on the hanger 21. When the servo motor 35 drives the first gear 33, the rotational driving force is transmitted to the driving wheel 32 through the second gear 34, thereby driving the hoisting mechanism to move around on the bridge frame body 1, so as to facilitate temperature monitoring of the temperature transfer structure at each monitoring point.

[0035] The right side of the hanging platform 3 is vertically slidably arranged as follows: Figure 1 As another important embodiment of the present invention, Figure 2 As shown, a plurality of monitoring units 5 are provided on the upper surface of the first driving block 4 for continuously monitoring the heat carried by the heat-conducting rod 14. Fig.10 As shown, the upper surface of the first driving block 4 is provided with a plurality of evenly arranged storage tanks 41, each storage tank 41 is inserted with a monitoring unit 5, the monitoring unit 5 comprises a sleeve 51, a temperature probe 52, a first storage battery 53 and a first magnetic block 54 of an annular structure, the sleeve 51 is slidably connected to the inner wall of the storage tank 41, the first storage battery 53 is arranged in the sleeve 51, a signal transmitter (not shown) is arranged on the first storage battery 53, the receiving end of the signal transmitter is connected to the temperature probe 52, and the first magnetic block 54 is fixedly installed on the top of the sleeve 51, as shown in FIG. Figure 7As shown, a second magnetic block 16 of an annular structure is fixedly installed on the heat-conducting rod 14, and the first driving block 4 is driven by a first electric push rod 36 arranged on the upper surface of the right side of the hanging platform 3. The monitoring unit 5 is provided with several, and only a small part is shown in the figure for illustration. When the thermal imaging device 31 detects that the heat-conducting rod 14 at the designated monitoring point is in a slightly abnormal state, the first control scheme is implemented. Specifically, the first driving block 4 is pushed upward as a whole by the first electric push rod 36, and the monitoring unit 5 is driven upward by the first driving block 4 and is set on the heat-conducting rod 14. The monitoring unit 5 is retained on the abnormal heat-conducting rod 14 for a long time by the magnetic attraction of the first magnetic block 54 and the second magnetic block 16. During the operation of the monitoring unit 5, the temperature of the surface of the heat-conducting rod 14 is obtained by the contact between the temperature probe 52 and the heat-conducting rod 14, and the first storage battery 53 supplies power to the temperature probe 52 and the signal transmitter. The temperature value obtained by the temperature probe 52 is sent to the temperature monitoring control module described in the following embodiment 2 through the signal transmitter, so as to facilitate the subsequent continuous movement of the hoisting mechanism and the continuous monitoring of the overheated monitoring point. The above-mentioned preferred scheme continuously performs remote monitoring of the designated temperature transfer structure (i.e., the heat-conducting rod 14) through the monitoring unit 5, which facilitates the continuous patrol movement of the lifting mechanism, avoids it spending too much time on one temperature abnormality point and resulting in failure to monitor other heat-conducting rods 14 in a timely manner, and further improves the intelligent temperature monitoring effect.

[0036] Continue reading Fig.10 Two symmetrical third magnetic blocks 55 are fixedly installed at the bottom of the sleeve 51, and two electromagnetic blocks 56 symmetrical to the third magnetic blocks 55 are arranged in the storage tank 41. When the temperature of the subsequent abnormal monitoring point returns to the normal value, the recovery plan is implemented, and the monitoring point is reached in the current detection path, and the first driving block 4 is driven to rise again by the first electric push rod 36. After the electromagnetic block 56 is energized, it generates magnetic attraction on the third magnetic block 55. The magnetic attraction generated by the electromagnetic block 56 on the third magnetic block 55 is greater than the force between the first magnetic block 54 and the second magnetic block 16. Therefore, the monitoring unit 5 is recovered to the designated storage tank 41, and the first battery 53 is subsequently charged through the contacts set at the bottom of the storage tank 41.

[0037] Two temperature transfer structures are provided at the same horizontal position, and the mounting blocks 12 in the two temperature transfer structures are fixedly connected by the limit blocks 17 of the inverted T-shaped structure, such as Figure 5 As shown, the limit block 17 abuts against the lower surface of the bridge body 1, and the two mounting blocks 12 are limited by the limit block 17 to prevent the temperature transfer structure from being squeezed and shifted when the first driving block 4 drives the monitoring unit 5 to move upward.

[0038] like Figure 3As shown, a second driving block 6 is vertically slidably provided on the left side of the hanging platform 3, a pressure groove 61 is provided in the second driving block 6, a fire extinguishing agent is provided in the pressure groove 61, an output port of the pressure groove 61 is connected to an electric control valve 62, an output end of the electric control valve 62 is connected to a jacking pipe 63, a conducting pipe 18 is fixedly installed below the bridge body 1, a sealing plug 19 is inserted in the conducting pipe 18 and located in the bridge body 1, the second driving block 6 is driven by a second electric push rod 37 provided on the upper surface of the left side of the hanging platform 3, when the temperature of the monitoring point is severely abnormal, the second control scheme is implemented, it is judged that a fire occurs in the bridge body 1, the second driving block 6 is driven to move upward as a whole by the second electric push rod 37, so that the jacking pipe 63 lifts the sealing plug 19, the pressure groove 61 is connected to the conducting pipe 18 by the electric control valve 62, so that the fire extinguishing agent is output to the bridge body 1 through the conducting pipe 18, and the fire is promptly extinguished at the point to avoid additional losses.

[0039] like Figure 3 and 4 As shown, a first positioning tube 110 of a C-shaped structure is provided on the limit block 17. The first positioning tube 110 and the limit block 17 are in an integrated structure. The first positioning tube 110 is conductive. A second positioning tube 111 is fixedly installed on the lower surface of the bridge body 1. Symmetrical refractors 112 are fixedly installed in the first positioning tube 110 and the second positioning tube 111. An attenuation sheet 113 is provided in the middle of the second positioning tube 111. The first driving block 4 is fixedly installed with a Figure 2 and 3 The infrared generating device 43 and the infrared receiving device 44 shown in the figure, the first positioning tube 110 is used to locate the placement position of the monitoring unit 5, and the second positioning tube 111 is used to locate the insertion position of the top pipe 63. The infrared generating device 43 emits infrared rays vertically upward. When the infrared generating device 43 is respectively directly below the right end ports of the first positioning tube 110 and the second positioning tube 111, the infrared rays are vertically guided downward by the refractor 112 in the first positioning tube 110 and the second positioning tube 111, and are received by the infrared receiving device 44 to achieve accurate positioning and avoid the driving wheel 32 from sliding and causing inaccurate movement. The infrared signal output from the second positioning tube 111 is weakened by the attenuation plate 113 in the second positioning tube 111, and signals of different intensities are output by the first positioning tube 110 and the second positioning tube 111 to distinguish the positioning position of the lifting mechanism.

[0040] like Figure 6 As shown, a through slot 38 is provided on the hanging platform 3, and a second battery 7 is provided in each of the first driving block 4 and the second driving block 6 through a mounting plate. Figure 8 The second battery 7 shown is used to supply power to the servo motor 35, the electric control valve 62, the first battery 53 and the electromagnetic block 56, and is also convenient for the staff to replace it, so as to maintain the monitoring of the monitoring point by the lifting mechanism.
