Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically to a switchgear contact temperature monitoring module bracket adapted to different cabinet types. Background Technology

[0002] As a crucial power distribution device in the power system, the long-term stable operation of key components such as internal contacts and connection points of switchgear directly affects the safety and reliability of the entire power distribution network. During the long-term operation of high currents, these components are prone to abnormal temperature rises due to material aging, increased contact resistance, or loose connections. If not detected and addressed in time, this may lead to equipment failure or even fire. Therefore, real-time monitoring of switchgear contact temperature has become an effective means to ensure the safe operation of power equipment.

[0003] Currently, there are various temperature monitoring modules available on the market for switchgear. They are typically fixed to a specific location in the switchgear using a dedicated mounting bracket so that the sensor can be aligned with or close to the contact being measured. However, in practical applications, it has been found that due to the differences in the internal structure of switchgear from different manufacturers and models, the support points, installation space, and specific positions of the contacts that can be used for mounting brackets vary. This makes it difficult to directly apply the monitoring module bracket designed for a specific switchgear type to other switchgear types. Utility Model Content

The two drive blocks 201 cooperate with the rectangular groove 101 to ensure that the two drive blocks 201 move stably in opposite directions.

[0036] The base 1 has two assembly components 3 fitted at its bottom. The assembly components 3 include guide plates 301. The bottoms of two drive blocks 201 are fixedly connected to the surfaces of the two guide plates 301 respectively. Right-angle assembly plates 302 are fixedly installed at both ends of the bottom of the guide plates 301. Two strip-shaped mounting slots 303 are opened on the right-angle assembly plates 302.

[0037] A U-shaped seat 4 is provided on the top of the base 1. An adjusting block 5 is fitted inside the U-shaped seat 4. Guide grooves are provided on the inner sides of both side plates of the U-shaped seat 4. The two sides of the adjusting block 5 are respectively engaged with the two guide grooves, which can improve the stability of the adjusting block 5 sliding inside the U-shaped seat 4. Locking bolts 6 are threaded on both side plates of the U-shaped seat 4. The front end of the locking bolt 6 passes through one side plate of the U-shaped seat 4 and abuts against the surface of the adjusting block 5.

[0038] In this embodiment,

[0039] Reference Figure 1 and Figure 3Two circular grooves are formed in the rectangular groove 101, and bearings are fitted in the circular grooves. The two ends of the bidirectional screw 2 are respectively fitted with the inner rings of the two bearings, which can ensure the rotation effect of the bidirectional screw 2 in the rectangular groove 101. One end of the bidirectional screw 2 passes through the circular groove to the outside of the base 1. A turntable is provided at one end of the bidirectional screw 2, which can facilitate the rotation of the bidirectional screw 2.

[0040] Reference Figure 1 and Figure 3 The base 1 has two limiting grooves at its bottom, and each of the two guide plates 301 has two limiting blocks. The limiting blocks cooperate with the limiting grooves to improve the stability of the two guide plates 301 moving towards each other at the bottom of the base 1.

[0041] Reference Figure 1 , Figure 2 and Figure 3 Both sides of the U-shaped seat 4 are provided with threaded holes 401. The locking bolt 6 cooperates with the threaded holes 401 to ensure the rotation effect of the locking bolt 6 on both sides of the U-shaped seat 4, and to ensure the locking effect of the locking bolt 6 on the adjusting block 5.

[0042] Reference Figure 1 The adjusting block 5 has positioning grooves 501 on both sides. The front end of the locking bolt 6 cooperates with the positioning groove 501 to ensure that the locking bolt 6 and the adjusting block 5 are tightly abutted, thereby improving the fixing effect of the adjusting block 5.

[0043] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The adjusting block 5 is equipped with a fixed platform 7, which has a slot 701. A locking block 8 fits into the slot 701, allowing for quick disassembly and reassembly between the locking block 8 and the fixed platform 7. Both ends of the bottom of the locking block 8 have receiving slots 801, and both receiving slots 801 are fitted with arc-shaped plates 802. Both ends of the arc-shaped plates 802 have arc-shaped surfaces, which facilitates the insertion and removal of the locking block 8 in the slot 701. A spring 803 is horizontally fixedly installed on one side of the arc-shaped plate 802. One end of the spring 803 is fixedly connected to the inner wall of the receiving slot 801, which allows the arc-shaped plate 802 to elastically resist the inner wall of the slot 701, ensuring the installation stability between the locking block 8 and the slot 701. The locking block 8 is equipped with a monitoring module 9, which is a wireless temperature sensor that can monitor the temperature inside the switch cabinet, thereby facilitating the disassembly and maintenance of the monitoring module 9.

[0044] The working process of this utility model is as follows: When the switch cabinet contact temperature monitoring module bracket designed according to this scheme and adapted to different cabinet types is in operation, firstly, a suitable installation point is selected according to the actual internal structure of the target switch cabinet. Then, the bracket is initially placed in the predetermined position, so that the right-angle mounting plates 302 of the two assembly components 3 are aligned with the installation points respectively. Then, the bidirectional screw 2 is rotated by the turntable. The rotation of the bidirectional screw 2 will drive the two driving blocks 201 on its surface to move synchronously in opposite directions or in opposite directions. The driving blocks 201 drive the guide plate 301 and the right-angle mounting plate 302 below them to move in a straight line at the bottom of the base 1, thereby adjusting the distance between the right-angle mounting plates 302 on the two guide plates 301 until the strip mounting groove 303 on the right-angle mounting plate 302 is aligned with the screw hole on the switch cabinet mounting surface. Then, the mounting bolts are passed through the strip mounting groove 303 and tightened. The position of the mounting bolts within the strip mounting groove 303 can be axially adjusted to fit the installation area inside the switchgear, thus firmly installing the bottom of the bracket inside the switchgear. The strip mounting groove 303 allows for fine-tuning before the bolts are tightened, further enhancing installation flexibility. After securing the bottom of the bracket, loosen the locking bolts 6 on both sides of the U-shaped base 4. At this point, the adjusting block 5 can slide freely up and down within the U-shaped base 4. Raise or lower the adjusting block 5 to a suitable height so that the sensor probe on the monitoring module 9 fixed at its top can accurately align with the switchgear contact to be monitored. After determining the height of the monitoring module 9, tighten the locking bolts 6 on both sides. The front end of the locking bolt 6 presses tightly against the positioning groove 501 on the adjusting block 5, using the friction between the front end of the locking bolt 6 and the inner wall of the positioning groove 501 to firmly lock the adjusting block 5.

[0045] When the monitoring module 9 needs to be disassembled and maintained, during the installation process, the clip 8 with the monitoring module 9 is inserted vertically into the slot 701 of the fixing platform 7. During the insertion process, the arc-shaped plates 802 on both sides of the clip 8 are squeezed inward by the side wall of the slot 701, compressing the spring 803. When the clip 8 is fully inserted, the rebound force generated by the compression of the spring 803 makes the arc-shaped plates 802 form a tight elastic contact with the inner wall of the slot 701, thereby achieving quick and stable installation of the monitoring module 9 without any tools. Similarly, when disassembling the monitoring module 9, the above operation is repeated in the reverse order to remove it as a whole, resulting in extremely high maintenance efficiency.

[0046] The monitoring module 9 and switch cabinet used in this utility model are existing known electrical devices, and both can be purchased and used directly on the market. Their structure, circuit and control principle are all existing known technologies. Therefore, the structure, circuit and control principle of the monitoring module 9 and switch cabinet will not be described in detail here.

[0047] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0048] 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.
