[0004] The main purpose of this invention is to provide a precise temperature measurement device for cable trays, aiming to improve the problem of inconvenient installation.

[0005] To achieve the above objectives, the present invention proposes a precise temperature measurement device for cable trays, comprising:

[0006] The base frame includes a base plate and two first side plates. The base plate connects the two first side plates. A cable is accommodated between the two first side plates. Each of the two first side plates has a connecting and fixing groove on the side away from each other. The bottom wall of the connecting and fixing groove has mounting holes, and multiple mounting holes are spaced apart.

[0007] Multiple temperature sensors, each corresponding to a specific temperature sensor and disposed within the mounting hole;

[0009] The top cover includes two second side panels, the first side panels are parallel to the second side panels, and the two first side panels are located between the two second side panels;

[0010] Each of the two second side plates has a drive plate at its bottom end. The distance between the drive plate and the first side plate gradually increases from top to bottom, so that when the top cover is placed on the base frame, the drive plate is used to press the assembly block into the connection fixing groove.

[0011] In one embodiment, the first side plate is provided with heat dissipation holes, and multiple heat dissipation holes are arranged at intervals.

[0012] In one embodiment, the plurality of heat dissipation holes are all located within the projection of the drive board in the horizontal direction.

[0032] Common cable trays are used for cable installation while also enabling cable temperature monitoring. A common type of protective cable tray with built-in temperature sensing components includes a base frame and a top cover. The base frame and top cover are connected on both sides by sliding grooves. Symmetrical connecting and fixing grooves are located on the center of both sides of the base frame, all facing inwards. The inner bottom surface of each connecting and fixing groove has a longitudinally penetrating sensor mounting hole, and a transversely penetrating cable routing groove. Several sensor mounting holes are arranged equidistantly laterally. An assembly block is located on the outer side of the cable routing groove. After the cables inside the connecting and fixing groove are installed, the top cover is often inserted into the connecting and fixing groove using a plug-in or snap-fit ​​method to install the assembly block. However, when snapping the assembly block into the connecting and fixing groove, the top cover deforms considerably, making installation somewhat inconvenient.

[0033] This utility model proposes a precise temperature measurement device for cable trays.

[0034] Please see Figure 1 , Figure 2 and Figure 3In one embodiment of this utility model, the cable tray precision temperature measuring device includes a base frame 1, multiple temperature sensors 2, two mounting blocks 3, and a top cover 4. The base frame 1 includes a base plate 11 and two first side plates 12. The base plate 11 connects to the two first side plates 12, and a cable is accommodated between the two first side plates 12. Each of the two first side plates 12 has a connecting and fixing groove 121 on its opposite side. The bottom wall of each connecting and fixing groove 121 has mounting holes 122, which are spaced apart. Multiple temperature sensors 2 are correspondingly positioned within the mounting holes 122. Two mounting blocks 3 correspond to two connecting and fixing grooves 121, and are positioned within the corresponding connecting and fixing grooves 121 to hold the temperature sensors 2. The top cover 4 includes two second side plates 41 and a top plate 42 connecting the two side plates 41. The first side plates 12 are parallel to the second side plates 41, and the two first side plates 12 are located between the two second side plates 41. Both of the second side plates 41 are provided with a drive plate 5 at their bottom ends. The distance between the drive plate 5 and the first side plate 12 gradually increases from top to bottom, so that when the top cover 4 is placed on the base frame 1, the drive plate 5 is used to press the assembly block 3 into the connection fixing groove 121.

[0035] In this invention, multiple temperature sensors 2 work together to improve the accuracy of temperature detection, thereby achieving precise temperature measurement of the cable. When the temperature sensor 2 is installed in the mounting hole 122 and the assembly block 3 is installed in the connecting fixing groove 121, by covering the base frame 1 with the top cover 4, the sides of the two drive plates 5 that are close to each other can respectively abut against the sides of the two assembly blocks 3 that are far apart. As the top cover 4 continues to move downward, the drive plates 5 can gradually press the assembly block 3 into the connecting fixing groove 121. As the cover moves downward, when the second side plate 41 abuts against the assembly block 3, it can press the assembly block 3 into the connecting fixing groove 121. The assembly block 3 undergoes elastic compression within the connecting fixing groove 121, which facilitates the installation of the assembly block 3 and ensures the pressing effect of the assembly block 3 on the temperature sensor 2, thus improving the problem of inconvenient installation.

[0036] The top cover 4 is connected to the base frame 1 by bolts. Specifically, the first side plate 12 and the second side plate 41 are fixedly connected by bolts. The second side plate 41 is provided with a threaded seat on its outer side. The first side plate 12 and the second side plate 41 are both provided with corresponding through holes. The bolts pass through the two through holes in sequence, and multiple bolts are arranged at intervals. Multiple bolts cooperate to achieve the fixation between the top cover 4 and the base frame 1.

[0037] The assembly pressure block 3 is made of a flexible material, such as a sponge block, capable of elastic deformation. Both the base plate 11 and the first side plate 12 can be metal plates, and they can be integrally formed by welding or stamping, without limitation. The base plate 11 and the first side plate 12 have the same length direction, with the base plate 11 being horizontal and the first side plate 12 being vertical. The temperature sensor 2 can be a resistance temperature detector (RTD) sensor or any other feasible temperature sensor 2, without limitation. The assembly pressure block 3 can be a pressure block with a certain degree of elasticity and has a certain high-temperature resistance. The second side plate 41 is a metal plate. After the top cover 4 is installed, it is fixedly connected to the base frame 1 by bolts; specifically, the first side plate 12 and the second side plate 41 are fixedly connected by bolts. The cable tray precision temperature measuring device includes a cable tray, which includes a base frame 1 and a top cover 4.

[0038] An arc transition surface 31 is provided between the two assembly blocks 3 and their respective end faces and upper end faces. By providing the arc transition surface 31, scratches caused by the drive plate 5 to the assembly blocks 3 can be reduced.

[0039] The cable tray precision temperature measurement device also includes a temperature-sensing optical cable, which is disposed between the two first side plates 12. By setting the temperature-sensing optical cable, it can cooperate with the temperature sensor 2 to increase the detection area of ​​the cable, and at the same time improve the accuracy and stability of the cable detection.

[0040] Please see Figure 1 , Figure 2 and Figure 3 The first side plate 12 has heat dissipation holes 123, and multiple heat dissipation holes 123 are spaced apart. The multiple heat dissipation holes 123 cooperate to facilitate the discharge of hot air between the two first side plates 12, thereby reducing the temperature rise of the cable.

[0041] The multiple heat dissipation holes 123 are all located within the horizontal projection of the drive plate 5. After the top cover 4 is installed, the drive plate 5 can cover the heat dissipation holes 123, ensuring the ventilation effect of the heat dissipation holes 123 while blocking rainwater to prevent it from passing through. Specifically, the highest heat dissipation hole 123 is lower than the highest height of the drive plate 5, and the lowest heat dissipation hole 123 is higher than the lowest height of the drive plate 5, ensuring the rainwater blocking effect of the drive plate 5.

[0042] The drive plate 5 can be an inclined plate or an arc-shaped plate, and there is no limitation here; specifically, the drive plate 5 is an arc-shaped plate.

[0043] The top cover 4 includes a top plate 42, which connects to two second side plates 41. After the top cover 4 is placed on the base frame 1, the top plate 42 can cover the upper side of the base plate 11 to cover and protect the cables from above. The top plate 42 and the second side plates 41 can be welded or integrally connected, which is not limited here; specifically, the top plate 42 and the second side plates 41 are integrally connected, and the base plate 11 and the second side plates 41 are formed by stamping.

[0044] Please see Figure 1 , Figure 3 and Figure 4 The assembly block 3 has an installation groove 32 corresponding to the mounting hole 122. The installation groove 32 is used to accommodate the temperature sensor 2. By providing a connecting fixing groove 121, the temperature sensor 2 can be easily installed on the assembly block 3, and then the assembly block 3 can be installed in the connecting fixing groove 121. By first installing the temperature sensor 2 on the assembly block 3, and then installing the assembly block 3 in the connecting fixing groove 121, and by aligning the installation groove 32 with the mounting hole 122, the installation space for the temperature sensor 2 is increased, and the installation difficulty of the temperature sensor 2 is reduced.

[0045] The assembly block 3 has a wiring groove 33 on the side near the connecting fixing groove 121. The temperature sensor 2 is connected to a wire, which is located in the wiring groove 33. By providing the wiring groove 33, when the temperature sensor 2 is installed on the assembly block 3, the wire can be buried in the wiring groove 33, thereby protecting the wire and reducing the need for subsequent wire laying.

[0046] The two first side plates 12 are recessed in a direction that brings them closer together to form the connecting and fixing groove 121. Specifically, the first side plates 12 are stamped to form the fixing groove, which allows for fast processing.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
