[0002] High-voltage motor junction boxes play a vital role in industrial enterprises. They are primarily used to protect and carry the electrical connections of electric motors, ensuring their proper operation and improving safety. They are widely used in industries such as petroleum and chemical engineering. Temperature and humidity monitoring is crucial for high-voltage motor junction boxes. By monitoring the temperature and humidity inside the junction box, abnormal temperature or humidity increases can be detected early. These abnormalities may indicate problems such as overheating of electrical equipment, moisture or corrosion of insulation materials, which could potentially cause fires, explosions, or other safety incidents. Therefore, temperature and humidity monitoring can help equipment identify potential hazards early, ensure safe operation, extend equipment life, and prevent potential failures, thereby improving the efficiency and operational optimization of industrial enterprises.

Therefore, it's necessary to install monitoring equipment inside the high-voltage motor junction box to obtain better monitoring data. Existing monitoring equipment installed inside a high-voltage motor junction box is typically fixed to the inner wall of the box, resulting in a relatively fixed installation position that's difficult to adjust. Consequently, it's impossible to quickly adjust the probe to accurately monitor sensitive areas.

DETAILED DESCRIPTION

[0029] During equipment operation, temperature monitoring of the cable connectors and base inlet and outlet areas within high-voltage motor junction boxes is crucial for preventing overheating and ensuring equipment safety. However, existing thermal imaging temperature measurement devices are bulky and require external power or screw fastening. Due to explosion-proofing, size, and structural considerations, the space inside high-voltage motor junction boxes is limited, making them inconvenient to install. Alternatively, installation of thermal imaging temperature measurement devices is complex, and after installation, they are unable to accurately monitor sensitive areas such as cable connectors and base inlet and outlet areas. For example, an existing infrared thermal imaging temperature separation monitoring device mounting bracket has one side connected to the bottom of the paver top beam, and the other side of the mounting bracket is used to mount the infrared thermal imager body. A reinforcement frame is provided between the protruding end of the mounting bracket and the side wall of the paver top beam. An adjustment plate is provided at the bottom of the mounting bracket, and a connecting plate is provided at the top of the infrared thermal imager body. The adjustment plate is hinged to the rear side of the connecting plate, and the adjustment plate is connected to the front side of the connecting plate by an adjustment bolt. The adjustment plate or the connecting plate is provided with an arc groove to match the adjustment bolt. The connection structure of this mounting bracket is relatively complex, not convenient for disassembly and assembly, and is not suitable for installing the monitoring equipment in the high-voltage motor junction box. For this reason, the utility model designs a mounting bracket that facilitates the installation of the monitoring equipment in the junction box.

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figures 1 to 4 As shown, the mounting bracket for monitoring equipment in a junction box of the present invention may include:

[0032] Installation frame 3, installation frame 3 is used to install the probe 4 of the monitoring equipment;

[0033] The clamping assembly 1 is used to be detachably mounted on the cable in the junction box to adjust the installation position of the monitoring device;

[0034] The adjusting component 2 is connected between the mounting frame 3 and the clamping component 1 . The adjusting component 2 can at least rotate to adjust the position of the mounting frame 3 .

[0035] Specifically, the mounting frame 3 has a mounting space for accommodating the monitoring device probe 4, which can be securely mounted and protected from external interference. The clamping assembly 1 serves as the fixed foundation for the entire mounting bracket. It is removably attached to the cable and provides stable support for the entire mounting bracket, enabling convenient installation of the monitoring device within the junction box. The adjustment assembly 2 is connected between the mounting frame 3 and the clamping assembly 1 and has at least the function of rotating and adjusting the mounting frame 3 to achieve flexible adjustment of the monitoring device, facilitating its installation and precise monitoring.

[0036] In general, the mounting bracket can detachably mount the monitoring device on the cable in the junction box through the cooperation of the clamping component 1 and the mounting frame 3, and then the mounting angle of the monitoring device can be rotated and adjusted through the adjustment component 2, so that the monitoring device can be installed at different positions on different cables according to the needs of different monitoring points, and it is easy to install and adjust, so that the monitoring pain points can be quickly aligned for precise monitoring. Such a mounting bracket has a simple structure and can be easily installed on the cables in the junction boxes of high and low voltage motors. It can meet the installation requirements of cables of different specifications and directions in the junction box, and can flexibly adjust the monitoring direction of the monitoring device. It is particularly suitable for the installation of thermal imaging temperature measuring devices in the junction boxes of high-voltage motors.

[0037] In one example, Figure 4 As shown, the clamping assembly 1 includes a first clamping member 11 and a second clamping member 12 . The first clamping member 11 and the second clamping member 12 cooperate to surround the outside of the cable, and the two are fastened to the cable through a first connecting member 13 .

[0038] Specifically, the clamping assembly 1 may include a first clamping member 11 and a second clamping member 12. The first clamping member 11 and the second clamping member 12 cooperate to form an embracing force that can be encircled and clamped on the outside of the cable. The first clamping member 11 and the second clamping member 12 are then connected by a first connecting member 13, so that the clamping assembly 1 can firmly clamp the cable to achieve stable installation of the entire mounting bracket, thereby ensuring the stability of the monitoring equipment.

[0039] In one example, the first clamping member 11 and the second clamping member 12 both include a semicircular arc structure and extension plates located on both sides of the semicircular arc structure, and the extension plates are both provided with connecting holes 14. The connecting holes 14 on the first clamping member 11 correspond one-to-one to the connecting holes 14 on the second clamping member 12, and the two corresponding connecting holes 14 are fastened together by the first connecting member 13.

[0040] Specifically, the first clamping member 11 and the second clamping member 12 have the same structure, both being semicircular in shape. The first clamping member 11 and the second clamping member 12 are symmetrically arranged, and their arc openings are positioned opposite each other to form a ring-shaped structure for clamping the cable. The extension plates on both sides of the first clamping member 11 and the second clamping member 12 are provided with connection holes 14. The first connecting member 13 passes through the corresponding connection holes 14 of the first clamping member 11 and the second clamping member 12 to achieve a secure connection, thereby enabling the clamping assembly 1 to firmly clamp the cable.

[0041] It should be noted that the first clamping member 11 and the second clamping member 12 are designed with a semicircular arc structure so as to match the outer structure of the cable and fit the cable more perfectly when clamping.

[0042] In one example, the first connecting member 13 is a threaded connecting member, and the first connecting member 13 cooperates with the connecting hole 14 to adjust the installation distance between the first clamping member 11 and the second clamping member 12 to accommodate cables of different sizes.

[0043] Specifically, the first connector 13 comprises a bolt and a nut. The bolt passes through two corresponding connection holes 14 and then engages with the nut. By rotating the nut, the distance between the first clamping member 11 and the second clamping member 12 can be adjusted, enabling the clamping assembly 1 to clamp cables of varying sizes. It should be noted that an embedded nut washer can be positioned where the connection holes 14 correspond to the nuts. This provides a shock-absorbing effect on the tightening connection of the first connector 13 when the motor vibrates, ensuring the effectiveness of the tightening connection.

[0044] It should be noted that the first clamping member 11 and the second clamping member 12 of the clamping assembly 1 may also be connected and fastened in other ways, such as snap-fit ​​connection and fixation.

[0045] In one example, the first clamping member 11 and the second clamping member 12 are both provided with a shock-absorbing insulating rubber pad 15 on the side closest to the cable. The presence of the shock-absorbing insulating rubber pad 15 on the inner side of the first clamping member 11 and the second clamping member 12 can significantly reduce the impact of motor vibration on the mounting bracket, ensuring that the monitoring device probe 4 can stably collect information from the monitoring point. Furthermore, by replacing the shock-absorbing insulating rubber pad 15 with different thicknesses, the device can be installed on cables of different sizes.

[0046] In one example, Figure 4 As shown, the adjustment assembly 2 includes a rotating seat 21 and a rotating head 22 . The rotating head 22 is a spherical structure, and the rotating seat 21 is provided with a spherical cavity for matching the rotating head 22 . The rotating head 22 can be rotated and adjusted within the rotating seat 21 .

[0047] Specifically, the rotating base 21 can be fixedly connected to the first clamping member 11 or the second clamping member 12, serving as the fixed end of the adjustment assembly 2. The rotating head 22 is connected to the mounting frame 3, serving as the movable end of the adjustment assembly 2. The rotating head 22 has a spherical structure, and the rotating base 21 defines a spherical cavity for matching the mounting of the rotating head 22. That is, when connected, the rotating base 21 is wrapped around the outside of the rotating head 22, and the rotating head 22 can be rotated and adjusted within the rotating base 21, thereby realizing the function of the adjustment assembly 2 to rotate and adjust the mounting frame 3.

[0048] In one example, Figure 4 As shown, the rotating base 21 has a plurality of petal-shaped portions 211 , which enclose a spherical cavity and a snap-in opening 212 located above the spherical cavity. The rotating head 22 is inserted into the rotating base 21 through the snap-in opening 212 .

[0049] Specifically, the rotating base 21 is designed to be composed of multiple petal-shaped portions 211, which not only form a spherical cavity for mounting the rotating head 22 but also enable a detachable connection with the rotating head 22. To install, the rotating head 22 can be inserted into the rotating base 21 through the snap-in opening 212, with the multiple petal-shaped portions 211 wrapped around the outside of the rotating head 22. To remove, the rotating head 22 can be removed from the rotating base 21 through the snap-in opening 212. This allows for a detachable connection between the rotating head 22 and the rotating base 21, facilitating maintenance or replacement of the monitoring device's probe 4.

[0050] It should be noted that although the spherical structure of the rotating head 22 can rotate unrestricted within the rotating seat 21, the connecting rod 24 is provided at the end connecting the rotating head 22 to the mounting frame 3. The connecting rod 24 can only rotate within the range of the snap-in opening 212. In other words, the rotation adjustment range of the mounting frame 3 is actually limited by the snap-in opening 212. The petal-shaped portion 211 has good flexibility and a certain degree of elasticity, so that when the rotating head 22 is disassembled, the snap-in opening 212 can be restored to its original size under the action of the elastic deformation force after being expanded.

[0051] In one example, Figure 4 As shown, the adjustment assembly 2 further includes a fastener 23. The fastener 23 is configured such that when the petal-shaped portion 211 is pressed against the rotating head 22, the rotating head 22 is restricted in position within the rotating seat 21. Thus, when the adjustment assembly 2 adjusts the position of the mounting frame 3 so that the probe 4 of the monitoring device is aligned with the monitoring point, the fastener 23 can press the petal-shaped portion 211 against the rotating head 22 to restrict the rotation of the rotating head 22 within the rotating seat 21, thereby preventing the position of the monitoring device probe 4 from being changed due to motor vibration, thereby ensuring the installation stability of the monitoring device.

[0052] In one example, the fastener 23 is sleeved on the rotating seat 21, the fastener 23 has an internal threaded hole, and the outer side of the petal-shaped portion 211 is provided with an external thread matching the internal threaded hole; when the fastener 23 is screwed, the fastener 23 squeezes the petal-shaped portion 211 and presses it toward the rotating head 22.

[0053] Specifically, the fastener 23 is an annular structure with an internally threaded hole within its inner ring. The outer sides of the multiple petal-shaped portions 211 of the rotating base 21 have external threads that mate with the internally threaded holes. When the fastener 23 is screwed onto the rotating base 21, the petal-shaped portions 211 are pressed against the rotating head 22, restricting the rotation of the rotating head 22 within the rotating base 21 and achieving a tightening effect.

[0054] Further, if Figure 3 and Figure 4 As shown, the outer side of the fastener 23 has a plurality of ridges 231 evenly distributed along its circumference. The ridges 231 are designed to facilitate rotating and tightening or loosening the fastener 23 .

[0055] In one example, Figure 3 and Figure 4 As shown, the adjustment assembly 2 further includes a connecting rod 24 , the two ends of which are respectively connected to the mounting frame 3 and the rotating head 22 , and the connecting rod 24 has a telescopic adjustment function.

[0056] Specifically, the mounting frame 3 is connected to the rotating head 22 via a connecting rod 24 . The connecting rod 24 has a telescopic adjustment function, so that the mounting frame 3 has a more flexible adjustment capability, so as to be applicable to more installation scenarios.

[0057] Furthermore, the connecting rod 24 has a curved structure, and the degree of its curvature is adjustable.

[0058] In one example, Figure 4 As shown, the mounting frame 3 includes a mounting plate 31 and a mounting shell 32. The mounting shell 32 and the mounting plate 31 can be connected by bolts. A sealing gasket 33 is provided between the mounting shell 32 and the mounting plate 31 to ensure a sealed space within the mounting frame 3, while reducing vibration between the mounting shell 32 and the mounting plate 31 and providing connection stability. The mounting plate 31 is detachably connected to the end of the connecting rod 24.

[0059] In order to better understand the above embodiment, the following is a further explanation with reference to the accompanying drawings, taking the application of the mounting bracket of the present invention to a thermal imaging temperature measuring device installed in a high-voltage motor junction box as an example.

[0060] All components of the mounting bracket are made of insulating materials with excellent aging resistance, capable of operating in high-temperature environments exceeding 100°C for extended periods. The thermal imaging temperature measurement device's probe 4, enclosed within a fully insulated mounting frame 3, houses a built-in temperature sensor and signal processing circuitry, enabling real-time temperature monitoring of the heating area and transmitting the data to an external monitoring system.

[0061] The clamping assembly 1 can be clamped on the cable in the high-voltage motor junction box by the cooperation of the first clamping member 11 and the second clamping member 12, and by selecting different lengths of the first connecting member 13 and different thicknesses of the shock-absorbing insulating rubber pad 15, the first clamping member 11 and the second clamping member 12 can be clamped and fastened on cables of different specifications (such as 35mm 2 ~630mm 2 )superior.

[0062] Adjustment assembly 2, through the cooperation of rotating head 22 and rotating base 21, adjusts the angle of mounting frame 3, enabling the thermal imaging temperature measurement device's probe 4 to freely adjust its angle in three dimensions, enabling quick alignment with cable connectors or the base's inlet and outlet areas for precise monitoring. After the angle of the thermal imaging temperature measurement device's probe 4 is adjusted, fasteners 23 compress the rotating base 21 and rotating head 22 to secure them. The strength of fasteners 23 ensures that the thermal imaging temperature measurement device's probe 4 does not deviate even under a certain degree of vibration.

[0063] In summary, the advantages of the mounting bracket of the present invention when used to install a thermal imaging temperature measuring device in a junction box, compared with the prior art, include at least the following:

[0064] The mounting bracket of the utility model has the advantages of good insulation performance, anti-aging, easy installation and maintenance, high strength and rigidity, and can be used in high-temperature environments for a long period of time. It can realize flexible monitoring and rapid adjustment of the temperature of the cable joint area and the base incoming line area in the junction box, and can improve the accuracy and convenience of temperature monitoring. It is suitable for real-time monitoring and early warning of the temperature in the junction box of high-voltage motors and in the hot spots in some large low-voltage motors.

[0065] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist.
