Description

Technical Field

[0001] The utility model relates to the technical field of temperature monitoring, in particular to an intelligent temperature monitoring device for a cable trench. Background Art

[0002] Cables can be seen everywhere in factories. In the power distribution room, a large number of cables are usually concentrated in the cable trench for easy wiring and maintenance. With the increase in electricity consumption, there are more and more cables in the cable trench. As long as the current passes through, the cables will heat up. At the same time, as the ambient temperature rises, it is very easy to cause fire hazards. There is no complete and effective monitoring solution for intelligent temperature monitoring of cable trenches in current technology.

[0003] The main cause of fire in cable trench is heating of power cables. In order to extinguish the fire in cable trench in time and avoid causing greater losses, the existing technology uses a monitoring device as shown in the prior art with publication number CN207199033U to monitor the cable trench. With the help of smoke sensors and temperature sensors in the device, the fire can be detected in time at the early stage and the processor can give an alarm. Although this technical solution can detect the fire inside the cable trench in time, the initial flame has already caused damage to the cable, causing economic losses to people. Therefore, there is a need for an intelligent temperature monitoring device for cable trenches that can monitor the temperature change at the fire location before the fire occurs.

The first display screen 42 and the second display screen 43 are used to display thermal images made by the transformation of infrared thermal radiation in the cable trench. The speaker 41 is used to emit a sound to warn when an abnormal change in infrared thermal radiation occurs, and the hard disk recorder 32 can be used to store videos and display them on the second display screen 43.

[0038] In addition, it is worth noting that the master control terminal 31 in the present utility model is equipped with an industrial temperature measurement monitoring system for equipment management, preview, alarm, temperature measurement, electronic map, and user management, which can meet basic temperature measurement monitoring needs;

[0039] It also supports different screen display modes: 1, 4, 6, 9, 16, 36, 64 screens, etc. It can also support 2, 6, 8 screens and other combination display modes. Users can choose between medium screen display and full screen display.

[0044] Furthermore, if Figure 3-6 As shown, a fire-proof camera protection assembly 12 is provided outside the infrared dual-light camera 11. The camera protection assembly 12 includes a protection cover 1201 covering the outside of the infrared dual-light camera 11. A bracket 12012 for fixing the protection cover 1201 in the cable trench is fixed to the rear side of the top of the protection cover 1201. The bracket 12012 is hoisted in the cable trench by bolts.

[0045] A camera mounting frame 1202 is slidably connected to the bottom of the protective cover 1201 through a slide rail, the infrared dual-light camera 11 is fixed to the rear side of the protective cover 1201 through bolts, an iron rod 1203 is fixed in the middle of the rear side of the camera mounting frame 1202, and an electromagnet 1204 for adsorbing the iron rod 1203 is fixed in the middle of the rear side of the protective cover 1201 to drive the camera mounting frame 1202 and the infrared dual-light camera 11 to be retracted into the protective cover 1201, and a protective door plate 1209 is rotatably connected to the top of the protective cover 1201 through a rotating shaft 1208. The protective door plate 1209 rotates with the infrared dual-light camera 11 retracting into the protective cover 1201 and blocks an opening on one side of the protective cover 1201, so that a fire occurs inside the cable trench. In case of a disaster, the electromagnet 1204 can be automatically energized and attract the iron rod 1203 to move toward the rear side of the protective cover 1201, so that the infrared dual-light camera 11 can be retracted into the protective cover 1201. At the same time, the utility model can also automatically seal the protective door plate 1209 on one side of the protective cover 1201 to shield and protect the infrared dual-light camera 11. The protective cover 1201, the protective door plate 1209 and the bracket 12012 in the utility model are all made of heat-insulating and fire-proof materials. The protective cover 1201, the protective door plate 1209 and the bracket 12012 made of the material can prevent the fire from damaging the infrared dual-light camera 11 in the utility model, which helps to protect the infrared dual-light camera 11.

[0046] In order to be able to automatically flip the protective door panel 1209 downward when a fire occurs, Figure 4 and 5 As shown, at both ends of the rotating shaft 1208, there are rotating shaft limit boxes 12013 movably connected through bearings, and the two rotating shaft limit boxes 12013 are respectively fixed to the front side and the rear side of the top end of the protective cover 1201, and the two ends of the rotating shaft 1208 extend to the inside of the two rotating shaft limit boxes 12013 respectively. The outside of both ends of the rotating shaft 1208 is wound with a coil spring 12010, one end of the coil spring 12010 is fixed to the outer wall of the rotating shaft 1208, and the other end of the coil spring 12010 is fixed to the inner wall of the rotating shaft limit box 12013, so as to ensure that the protective door panel 1209 is in a vertical upward state, as shown in FIG. Figure 3 As shown;

[0047] A hanging ring 1206 is fixed on one side of the top of the infrared dual-light camera 11, and a pull rope 1207 is connected to the outer end of the hanging ring 1206. The pull rope 1207 passes through the top wall of the protective cover 1201 and is wound around the outer end of the rotating shaft 1208. One end of the pull rope 1207 passing through the top wall of the protective cover 1201 is fixed to the outer wall of the rotating shaft 1208. A round box 12011 is movably connected to the middle of the outer end of the rotating shaft 1208 through a bearing, and the round box 12011 is embedded in the middle of the protective door panel 1209.

[0048] When a fire occurs, the infrared dual-light camera 11 drives the hanging ring 1206 to move toward the rear side of the protective cover 1201, and at the same time pulls one end of the pull rope 1207 to move. Since the pull rope 1207 is wound around the outer end of the rotating shaft 1208, the pull rope 1207 can drive the rotating shaft 1208 to rotate after being pulled, so that the rotating shaft 1208 can drive the protective door panel 1209 to flip downward, such as Figure 6 As shown, the protective door plate 1209 can block the opening at one end of the protective cover 1201, so that the protective door plate 1209 can prevent the flame in the cable trench from burning onto the infrared dual-light camera 11 and causing damage to the infrared dual-light camera 11.

[0049] In addition, after the flame is extinguished, the electromagnet 1204 is automatically powered off, because a plurality of springs 1205 are fixed on the rear side of the camera mounting frame 1202, and the plurality of springs 1205 are distributed on the outside of the iron rod 1203 in a circular array with the center of the iron rod 1203 as the center of the circle, and one end of the spring 1205 away from the camera mounting frame 1202 is fixed to the inner rear wall of the protective cover 1201, and the spring 1205 is compressed when the rear end of the camera mounting frame 1202 moves backward, so when the electromagnet 1204 is powered off, the previously compressed spring 1205 will push the camera mounting frame 1202 and the infrared dual-light camera 11 forward, and at the same time, the protective door panel 1209 can automatically rotate upward under the elastic force of the coil spring 12010 and return to the position as shown in FIG. Figure 3 The position shown enables the infrared dual-light camera 11 to continue monitoring the cables in the cable trench.

[0050] It is worth noting that the on-off control of the electromagnet 1204 in the present invention can be achieved through the circuit structure in the prior art, which will not be further elaborated here.

[0051] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
