Description

Technical Field

[0001] This utility model relates to the field of cable tray temperature monitoring technology, specifically a temperature-controlled cable tray. Background Technology

[0002] In power supply and distribution systems, cables are mainly laid in cable trays. Due to increased load or undersized cable trays, there are many cables in the cable trays. During power transmission, the cables heat up quickly. Long-term operation with the cables heating up will seriously affect the cable insulation and service life, and may even cause fires due to power failures.

[0003] Chinese Utility Model Patent Publication No. CN 220585890 U discloses a temperature-controlled cable tray. This cable tray can monitor the internal temperature of power distribution cable trays located at high altitudes in real time, allowing power inspection personnel to promptly understand the heating status of cables within the tray. Power inspection personnel can then promptly identify any potential electrical hazards and conduct timely inspections and repairs, ensuring electrical safety and preventing fires caused by power failures. However, while this temperature-controlled cable tray can monitor the temperature of the cable tray, its installation structure is not designed to facilitate rapid installation of the temperature monitor and subsequent maintenance. Furthermore, the lack of a limiting design for the connecting wires can easily lead to a chaotic distribution of connecting wires within the cable tray, potentially causing tangling and malfunctions, thus affecting normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a temperature-controlled cable tray, which can effectively solve the problems of existing technologies that do not have an installation structure design, which makes it inconvenient for the rapid installation of temperature monitors and the maintenance of temperature inspection equipment. Furthermore, the lack of a limiting design for the connecting wires makes it easy for the connecting wires to be distributed haphazardly in the cable tray, which can easily lead to tangling and failure, affecting normal use.

[0005] The technical solution adopted by this utility model is as follows: a temperature-controlled cable tray includes a cable tray base frame, a slot is provided on the outer surface of the cable tray base frame, an insert is installed on the outer surface of the cable tray base frame through the slot, a cover plate is fixedly installed on the other end of the insert away from the slot, a positioning hole is provided through the outer surface of the cover plate, a groove is provided on the outer surface of the cable tray base frame, a mounting bracket is provided on the inner surface of the cable tray base frame, a mounting groove is provided on the outer surface of the mounting bracket, a positioning bolt is threadedly connected to the outer surface of the mounting groove, a temperature monitor body is fixedly installed on the outer surface of the mounting bracket, a mounting frame is provided on the outer surface of the temperature monitor body, and a limit bolt is provided through the outer surface of the mounting frame.

[0006] Preferably, the slot is adapted to the insert, and the outer surface of the bottom frame of the cable tray is provided with a second positioning hole, and the first positioning hole and the second positioning hole are in one-to-one correspondence.

[0007] The above technical solution involves first inserting the insert strip into the slot of the cable tray bottom frame, so that the cover plate initially covers the cable tray bottom frame. Then, the positioning hole one and positioning hole two are aligned. The matching design of the slot and the insert strip makes the connection and installation of the cover plate and the cable tray bottom frame convenient and quick, without the need for complicated connection tools and processes, thus improving installation efficiency. The one-to-one correspondence between positioning hole one and positioning hole two provides a basis for the subsequent precise fixing of the cover plate, which can effectively prevent the cover plate from shifting during the installation process and ensure the integrity and stability of the overall structure of the cable tray.

[0008] Preferably, the positioning hole one and positioning hole two are provided in two identical sets, and each set of the positioning hole one and positioning hole two is provided with four identical sets. The positioning bolt passes through the positioning hole one and positioning hole two and extends into the interior of the mounting groove.

[0009] With the above technical solution, after aligning positioning hole one and positioning hole two, the positioning bolts are passed through positioning hole one and positioning hole two in sequence and screwed into the installation groove and tightened. The design of multiple sets and multiple positioning holes makes the connection between the cover plate and the bottom frame of the cable tray more secure. The evenly distributed positioning bolts can make the cover plate bear the force evenly, avoiding the loosening or damage of the connection due to uneven local force, enhancing the overall stability of the cable tray, and ensuring the safe laying of cables in the cable tray.

[0010] Preferably, the outer surface of the temperature monitor body is provided with a control switch and a connecting wire, and the connecting wire is adapted to the groove.

[0011] With the above technical solution, when installing the temperature monitor body, the control switch and connecting wire are aligned in the correct positions, and the connecting wire is placed in the second groove. The second groove provides space for the connecting wire, allowing it to be arranged orderly in the bottom frame of the cable tray. This avoids the connecting wires being distributed haphazardly inside the cable tray, preventing the risk of failure caused by tangled connecting wires, maintaining the neatness and aesthetics of the inside of the cable tray, and facilitating subsequent maintenance and repair work. At the same time, the control switch facilitates the operation and control of the temperature monitor body.

[0012] Preferably, the size of the groove is the same as the size of the temperature monitor body, and the temperature monitor body extends through the groove to the outer surface of the cable tray bottom frame.

[0013] Through the above technical solution, the temperature monitor body passes through the groove 1 from inside the bottom frame of the cable tray, so that part of the temperature monitor body is located on the outer surface of the bottom frame of the cable tray. The size design of the groove 1 can accurately accommodate the temperature monitor body, so that the installation position of the temperature monitor body on the bottom frame of the cable tray is fixed and stable, and its monitoring accuracy will not be affected by shaking or displacement.

[0014] Preferably, a sensing probe is provided at the other end of the temperature monitor body away from the control switch, and the sensing probe passes through the mounting bracket and extends to its inner side.

[0015] With the above technical solution, when installing the temperature monitor, the sensing probe extends through the mounting bracket to the inside. The sensing probe, located inside the mounting bracket, can directly contact the cables or air environment inside the cable tray, accurately sensing temperature changes and providing precise temperature data to the temperature monitor. This allows for timely detection of abnormal temperatures during cable operation, ensuring the safe operation of the cable and preventing safety accidents such as fires caused by excessive temperatures.

[0016] Preferably, the positioning bolts are provided in two identical sets, and the two sets of positioning bolts are symmetrically distributed about the center line of the mounting frame.

[0017] Through the above technical solution, when fixing the mounting bracket to the inner surface of the cable tray bottom frame, two sets of positioning bolts are installed in the corresponding positions and tightened. The symmetrically distributed positioning bolts make the mounting bracket more stable on the inner surface of the cable tray bottom frame, and the force is even, avoiding the mounting bracket from tilting or loosening due to uneven force. This ensures the stable operation of the temperature monitor body on the mounting bracket and improves the reliability and stability of the entire temperature-controlled cable tray temperature monitoring system.

[0018] Compared with the prior art, this utility model provides a temperature-controlled cable tray, which has the following advantages:

[0019] 1. The temperature-controlled cable tray features a slot and insert design that makes the connection and installation of the cover plate to the bottom frame of the cable tray convenient and quick, without the need for complicated connection tools and processes, thus improving installation efficiency. The one-to-one correspondence between positioning hole one and positioning hole two provides a basis for the subsequent precise fixing of the cover plate, which can effectively prevent the cover plate from shifting during the installation process and ensure the integrity and stability of the overall structure of the cable tray.

[0020] 2. When installing the temperature monitor body of this temperature-controlled cable tray, the sensing probe extends through the mounting frame to the inside. The sensing probe, located inside the mounting frame, can directly contact the cables or air environment inside the cable tray to accurately sense temperature changes and provide precise temperature data for the temperature monitor body. When installing the temperature monitor body, align its control switch and connecting wires in the correct positions and place the connecting wires in the second groove. The second groove provides space for the connecting wires, allowing them to be arranged orderly within the bottom frame of the cable tray. This avoids the connection wires being distributed haphazardly inside the cable tray, preventing the risk of failure caused by tangled connecting wires and maintaining the neatness and aesthetics of the inside of the cable tray, facilitating subsequent maintenance and repair work.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-7 As shown, the present invention provides a temperature-controlled cable tray, including a cable tray base frame 1, a slot 2 on the outer surface of the cable tray base frame 1, an insert strip 3 inserted into the slot 2 on the outer surface of the cable tray base frame 1, a cover plate 4 fixedly installed at the other end of the insert strip 3 away from the slot 2, a positioning hole 5 through the outer surface of the cover plate 4, a groove 6 and a groove 7 on the outer surface of the cable tray base frame 1, a mounting bracket 8 on the inner surface of the cable tray base frame 1, a mounting groove 9 on the outer surface of the mounting bracket 8, a positioning bolt 10 threadedly connected to the outer surface of the mounting groove 9, a temperature monitor body 11 fixedly installed on the outer surface of the mounting bracket 8, a mounting frame 15 on the outer surface of the temperature monitor body 11, and a limit bolt 16 through the outer surface of the mounting frame 15.

[0031] Specifically, slot 2 is compatible with insert strip 3. The outer surface of the cable tray bottom frame 1 has a second positioning hole 17. Positioning hole 5 and positioning hole 17 are one-to-one corresponding. The advantage is that insert strip 3 is first inserted into slot 2 of cable tray bottom frame 1 so that cover plate 4 initially covers cable tray bottom frame 1. Then, positioning hole 5 and positioning hole 17 are aligned. The compatible design of slot 2 and insert strip 3 makes the connection and installation of cover plate 4 and cable tray bottom frame 1 convenient and quick, without complicated connection tools and processes, thus improving installation efficiency. The one-to-one correspondence of positioning hole 5 and positioning hole 17 provides a basis for the subsequent precise fixing of cover plate 4, which can effectively prevent cover plate 4 from shifting during installation and ensure the integrity and stability of the overall structure of the cable tray.

[0032] Specifically, positioning holes 1-5 and positioning holes 2-17 are provided in two identical sets, with four identical positioning holes 1-5 and positioning holes 2-17 in each set. Positioning bolts 10 pass through positioning holes 1-5 and positioning holes 2-17 and extend into the interior of the mounting groove 9. The advantage is that after positioning holes 1-5 and positioning holes 2-17 are aligned, positioning bolts 10 are passed through positioning holes 1-5 and positioning holes 2-17 in sequence and screwed into the mounting groove 9 to tighten. The design of multiple sets and multiple positioning holes makes the connection between the cover plate 4 and the bottom frame 1 of the cable tray more secure. The evenly distributed positioning bolts 10 can make the cover plate 4 bear the force evenly, avoiding the loosening or damage of the connection due to uneven local force, enhancing the overall stability of the cable tray, and ensuring the safe laying of cables in the cable tray.

[0033] Specifically, the outer surface of the temperature monitor body 11 is provided with a control switch 12 and a connecting wire 13. The connecting wire 13 is adapted to the groove 7. The advantage is that when installing the temperature monitor body 11, the control switch 12 and the connecting wire 13 are aligned and the connecting wire 13 is placed in the groove 7. The groove 7 provides space for the connecting wire 13, so that the connecting wire 13 can be arranged in an orderly manner in the bottom frame 1 of the cable tray. This avoids the connecting wire 13 being distributed messily in the cable tray, which not only prevents the risk of failure caused by the connecting wire 13 being tangled, but also keeps the inside of the cable tray neat and beautiful, which is convenient for subsequent maintenance and repair work. At the same time, the control switch 12 makes it convenient to operate and control the temperature monitor body 11.

[0034] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the size of the groove 6 is the same as that of the temperature monitor body 11. The temperature monitor body 11 passes through the groove 6 and extends to the outer surface of the cable tray base frame 1. The advantage is that by passing the temperature monitor body 11 through the groove 6 from inside the cable tray base frame 1, a portion of the temperature monitor body 11 is located on the outer surface of the cable tray base frame 1. The size design of the groove 6 can precisely accommodate the temperature monitor body 11, making the installation position of the temperature monitor body 11 on the cable tray base frame 1 fixed and stable, and preventing the accuracy of its monitoring from being affected by shaking or displacement.

[0036] Specifically, a sensing probe 14 is provided at the other end of the temperature monitor body 11 away from the control switch 12. The sensing probe 14 passes through the mounting bracket 8 and extends to its inner side. The advantage is that when installing the temperature monitor body 11, the sensing probe 14 passes through the mounting bracket 8 and extends to its inner side. The sensing probe 14 is located inside the mounting bracket 8 and can directly contact the cable or air environment in the cable tray, accurately sense temperature changes, and provide accurate temperature data for the temperature monitor body 11 so as to detect abnormal temperature conditions during cable operation in a timely manner, ensure the safe operation of the cable, and prevent safety accidents such as fires caused by excessive temperature.

[0037] Specifically, the positioning bolts 10 are provided in two identical sets, which are symmetrically distributed about the center line of the mounting bracket 8. The advantage is that when the mounting bracket 8 is fixed to the inner surface of the cable tray bottom frame 1, the two sets of positioning bolts 10 are installed in the corresponding positions and tightened. The symmetrical distribution of the positioning bolts 10 makes the installation of the mounting bracket 8 on the inner surface of the cable tray bottom frame 1 more stable and the force is even. This avoids the mounting bracket 8 from tilting or loosening due to uneven force, ensuring the stable operation of the temperature monitor body 11 on the mounting bracket 8 and improving the reliability and stability of the entire temperature-controlled cable tray temperature monitoring system.

[0038] Working principle: In use, first insert the insert strip 3 into the slot 2 of the cable tray bottom frame 1, so that the cover plate 4 initially covers the cable tray bottom frame 1. Then, align the positioning hole 5 with the positioning hole 17. The matching design of the slot 2 and the insert strip 3 makes the connection and installation of the cover plate 4 to the cable tray bottom frame 1 convenient and quick, without the need for complicated connection tools and processes, thus improving installation efficiency. The one-to-one correspondence between the positioning hole 5 and the positioning hole 17 provides a basis for the subsequent precise fixing of the cover plate 4, effectively preventing the cover plate 4 from shifting during installation and ensuring the integrity and stability of the overall cable tray structure. After aligning the positioning hole 5 with the positioning hole 17, pass the positioning bolt 10 through the positioning hole 5 and the positioning hole 17 in sequence and screw it in for installation. Tightening within groove 9, the design of multiple sets and positioning holes makes the connection between cover plate 4 and cable tray bottom frame 1 more secure. Evenly distributed positioning bolts 10 ensure uniform force distribution on cover plate 4, preventing loosening or damage due to uneven localized force, thus enhancing the overall stability of the cable tray and ensuring the safe laying of cables within the tray. When installing the temperature monitor body 11, align its control switch 12 and connecting wire 13, placing the connecting wire 13 in groove 7. Groove 7 provides space for the connecting wire 13, allowing it to be arranged orderly within the cable tray bottom frame 1, preventing a chaotic distribution of the connecting wire 13 and mitigating the risk of malfunctions caused by tangled connecting wires. This design maintains the neatness and aesthetics of the cable tray interior, facilitating subsequent maintenance and repair. Simultaneously, the control switch 12 allows for convenient operation and control of the temperature monitor body 11. The temperature monitor body 11 is inserted through the groove 6 from inside the cable tray bottom frame 1, with a portion of it positioned on the outer surface of the bottom frame 1. The groove 6 is precisely designed to accommodate the temperature monitor body 11, ensuring a fixed and stable installation position on the cable tray bottom frame 1, preventing any impact on monitoring accuracy due to shaking or displacement. During installation, the sensing probe 14 extends through the mounting bracket 8 to the inside, allowing direct contact with the cable tray interior. The system accurately senses temperature changes in the cable or air environment, providing precise temperature data to the temperature monitor 11. This allows for timely detection of temperature anomalies during cable operation, ensuring safe cable operation and preventing accidents such as fires caused by excessive temperatures. When fixing the mounting bracket 8 to the inner surface of the cable tray bottom frame 1, two sets of positioning bolts 10 are installed in their respective positions and tightened. The symmetrically distributed positioning bolts 10 make the mounting bracket 8 more stable on the inner surface of the cable tray bottom frame 1, ensuring even force distribution and preventing tilting or loosening of the mounting bracket 8 due to uneven force distribution. This guarantees the stable operation of the temperature monitor 11 on the mounting bracket 8 and improves the reliability and stability of the entire temperature-controlled cable tray temperature monitoring system.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
