Description

Technical Field

[0001] This utility model relates to the field of temperature monitoring equipment technology, and in particular to a non-contact, passive wireless temperature measurement device. Background Technology

[0002] Overheating of electrical equipment caused by factors such as loose connections and abnormally increased contact resistance has become one of the core hidden dangers leading to major safety accidents. Therefore, real-time temperature monitoring of key nodes of electrical equipment is particularly important, and deploying temperature monitoring devices can effectively ensure the safety of equipment operation.

[0003] Currently, passive wireless temperature measurement devices are commonly used to monitor the temperature of electrical equipment. Traditional passive wireless temperature measurement devices typically integrate the induction power supply module and the temperature measurement module. Under the constraints of complex and varied on-site busbar routing and installation space, it is often difficult for the induction power supply module to achieve precise alignment with the busbar, which in turn causes fluctuations in power extraction efficiency or even power supply interruption, affecting the normal operation of the temperature measurement module.

[0004] Therefore, to address the above issues, a non-contact, passive wireless temperature measurement device can be designed. By deploying the temperature measurement module and the inductive power supply module separately and configuring an installation mechanism with omnidirectional adjustment, the alignment problem between the inductive power supply module and the busbar can be effectively solved, thereby ensuring stable power supply and continuous and reliable power supply, and providing long-term energy support for the temperature measurement module. Utility Model Content

[0005] In order to overcome the problem that traditional passive wireless temperature measurement devices usually adopt an integrated structure for the induction power supply module and the temperature measurement module, under the complex and ever-changing field bus routing and installation space constraints, it is often difficult for the induction power supply module to achieve precise alignment with the bus, which in turn causes fluctuations in power extraction efficiency or even power supply interruption, affecting the normal operation of the temperature measurement module.

[0006] The technical solution of this utility model is as follows: a non-contact installation passive wireless temperature measurement device, including a base, a mounting frame, a support assembly, a current transformer, and a fiber optic temperature measurement device. The support assembly is set at the upper end of the base, and the mounting frame is set at the upper end of the support assembly. Two sets of mounting shafts are symmetrically rotatably connected inside the mounting frame. Mounting blocks are fixedly installed on the periphery of the mounting shafts. A ball joint seat is fixedly installed at one end of the mounting block. A mounting plate is fixedly installed at the movable end of the ball joint seat. The current transformer and the fiber optic temperature measurement device are respectively fixedly installed on one side of the two sets of mounting plates.

[0007] Preferably, by setting up support components to support and install the mounting frame, setting up mounting shafts to support and install the mounting blocks, and using the mounting blocks to support and install the ball joint seat, the position of the ball joint seat can be adjusted. By setting up the ball joint seat to support and install the mounting plate, and using two sets of mounting plates to install the current transformer and the fiber optic temperature measuring equipment respectively, the angles of the current transformer and the fiber optic temperature measuring equipment can be freely adjusted based on the position adjustment. On the one hand, this can solve the problem of alignment between the current transformer and the busbar, thereby ensuring stable power supply and continuous and reliable power supply, providing long-term energy support for the fiber optic temperature measuring equipment. On the other hand, it can easily align the fiber optic temperature measuring equipment with the temperature measuring point, significantly improving the adaptability of the device to complex installation scenarios.

[0008] Preferably, the support assembly includes a sleeve and a support rod, with the sleeve fixedly installed at the upper end of the base and the support rod slidably connected inside the sleeve.

[0009] Preferably, the support assembly includes elastic threaded plates, anti-slip pads, and nuts. Multiple sets of elastic threaded plates are evenly arranged circumferentially at the upper opening of the sleeve. Anti-slip pads are provided on the inner side of the elastic threaded plates, and nuts are threadedly connected to the outer side of the elastic threaded plates.

[0010] Preferably, the mounting bracket has an internal cavity, and an inspection cover is hinged to the upper end of the mounting bracket, with the inspection cover located at the opening of the internal cavity.

[0011] Preferably, the inner cavity has wire-passing grooves on the two side walls corresponding to the mounting shaft, and heat dissipation holes on the other two side walls.

[0012] Preferably, the locking assembly includes a pre-drilled hole, a handle, a rod, and a spring. Multiple sets of pre-drilled holes are evenly provided on the side wall of the mounting bracket along the circumferential axis of the mounting shaft. A handle is fixedly installed at one end of the mounting shaft. A rod is slidably connected inside the handle. A spring is fixedly installed between the rod and the handle. One end of the rod is inserted into the interior of a set of pre-drilled holes.

[0013] The beneficial effects of this utility model are:

[0014] The height and direction of the mounting bracket can be adjusted by the lifting, sliding, and rotating movement of the support rod within the sleeve. After adjustment, the support rod is locked in place by the cooperation of the nut and the elastic threaded plate. Then, the handle is rotated to drive the mounting shaft to rotate. When the mounting block is adjusted to the appropriate position with the mounting shaft, the insertion rod is released. The pressure generated by the spring's recovery deformation causes the end of the insertion rod to automatically insert into the corresponding reserved hole, locking the mounting shaft. This allows the current transformer and fiber optic temperature measurement equipment to be adjusted to the appropriate installation position. By adjusting the ball joint seat, the angle of the current transformer and fiber optic temperature measurement equipment can be freely adjusted based on the position adjustment. On the one hand, this solves the alignment problem between the current transformer and the busbar, thereby ensuring stable power supply and continuous reliable power supply, providing long-term energy support for the fiber optic temperature measurement equipment. On the other hand, it makes it easy to align the fiber optic temperature measurement equipment with the temperature measurement point, significantly improving the adaptability of the device to complex installation scenarios.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 and Figure 3This utility model provides an embodiment: a non-contact, passive wireless temperature measurement device, including a base 1, a mounting frame 2, a support assembly, a current transformer 6, and a fiber optic temperature measuring device 7. The support assembly is located at the upper end of the base 1, and the mounting frame 2 is located at the upper end of the support assembly. Two sets of mounting shafts 201 are symmetrically rotatably connected inside the mounting frame 2. Mounting blocks 202 are fixedly mounted on the periphery of the mounting shafts 201. A ball joint seat 203 is fixedly mounted at one end of the mounting block 202, and a mounting plate 204 is fixedly mounted at the movable end of the ball joint seat 203. The current transformer 6 and the fiber optic temperature measuring device 7 are respectively fixedly mounted on one side of the two sets of mounting plates 204. The mounting frame 2 is supported and installed by the support assembly, and the mounting shafts 201 are used to support the current transformer 6. The mounting block 202 provides support and installation, and the ball joint seat 203 is also supported and installed via the mounting block 202, allowing for position adjustment of the ball joint seat 203. The mounting plate 204 is supported and installed via the ball joint seat 203, and the current transformer 6 and the fiber optic temperature measuring device 7 are installed via two sets of mounting plates 204 respectively. Based on position adjustment, the angles of the current transformer 6 and the fiber optic temperature measuring device 7 can be freely adjusted. On the one hand, this solves the alignment problem between the current transformer 6 and the busbar, thereby ensuring stable power supply and continuous and reliable power supply, providing long-term energy support for the fiber optic temperature measuring device 7. On the other hand, it facilitates the alignment of the fiber optic temperature measuring device 7 with the temperature measuring point, significantly improving the adaptability of the device to complex installation scenarios.

[0022] Please see Figure 1 and Figure 4 In this embodiment, the support assembly includes a sleeve 301 and a support rod 302. The sleeve 301 is fixedly installed on the upper end of the base 1, and the support rod 302 is slidably connected to the inside of the sleeve 301. The support assembly includes an elastic threaded plate 303, an anti-slip pad 304, and a nut 305. Multiple sets of elastic threaded plates 303 are evenly arranged circumferentially at the upper opening of the sleeve 301. An anti-slip pad 304 is provided on the inner side of the elastic threaded plate 303, and a nut 305 is threadedly connected to the outer periphery of the elastic threaded plate 303. By setting the lifting, sliding, and rotating movements of the support rod 302 within the sleeve 301, the height and direction of the mounting bracket 2 can be adjusted. After adjustment, the support rod 302 is pressed and locked by the cooperation of the nut 305 and the elastic threaded plate 303, and the friction coefficient is increased by the direct contact between the anti-slip pad 304 and the support rod 302, ensuring the reliability of the locked state of the support rod 302.

[0023] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, the mounting frame 2 has an inner cavity 4, and an inspection cover 401 is hinged to the upper end of the mounting frame 2. The inspection cover 401 is located at the opening of the inner cavity 4. The inner cavity 4 has wire grooves 403 on both sides of the side wall corresponding to the mounting shaft 201, and heat dissipation holes 402 on the other two sides of the side wall. The inner cavity 4 can be integrated to install the electrical control unit and related wiring connection devices for controlling the current transformer 6 and the fiber optic temperature measuring device 7. The inspection cover 401 facilitates the installation and maintenance of the equipment in the inner cavity 4. The wire grooves 403 enable the wiring connection between the equipment in the inner cavity 4 and the external current transformer 6 and fiber optic temperature measuring device 7. The heat dissipation holes 402 ensure the effective dissipation of heat from the electronic components inside the inner cavity 4. The locking assembly includes a reserved hole 501, a handle 502, a plug 503, and a spring 504. Multiple sets of pre-drilled holes 501 are evenly provided on the side wall of the mounting bracket 2 along the circumferential axis of the mounting shaft 201. A rotating handle 502 is fixedly installed at one end of the mounting shaft 201. A plug rod 503 is slidably connected inside the rotating handle 502. A spring 504 is fixedly installed between the plug rod 503 and the rotating handle 502. One end of the plug rod 503 is inserted into the interior of a set of pre-drilled holes 501. By pulling up the plug rod 503 and stretching the spring 504, the rotating handle 502 can be unlocked. Thus, the mounting shaft 201 can be rotated by the rotating handle 502. When the mounting block 202 rotates to the appropriate position with the mounting shaft 201, the plug rod 503 is released. The spring 504 provides pressure to the plug rod 503, so that one end of the plug rod 503 is stably inserted into the appropriate pre-drilled hole 501. Thus, the mounting shaft 201 is locked by the rotating handle 502.

[0024] During operation, the entire device is installed in a suitable position using the base 1. The height and direction of the mounting bracket 2 can be adjusted by the lifting, sliding and rotating movement of the support rod 302 within the sleeve 301. After adjustment, the support rod 302 is pressed and locked by the cooperation of the nut 305 and the elastic threaded plate 303. The friction coefficient is increased by the direct contact between the anti-slip pad 304 and the support rod 302, ensuring the reliability of the locked state of the support rod 302.

[0025] Then, pulling up the insertion rod 503 and stretching the spring 504 can release the locking state of the handle 502, thereby rotating the mounting shaft 201 by rotating the handle 502. When the mounting block 202 is adjusted to the appropriate position with the mounting shaft 201, the insertion rod 503 is released, and the pressure generated by the spring 504 restoring its deformation causes the end of the insertion rod 503 to automatically insert into the corresponding reserved hole 501, locking the mounting shaft 201.

[0026] The current transformer 6 and the fiber optic temperature measuring device 7 can be adjusted to suitable installation positions. Then, the ball joint seat 203 can be adjusted to allow for free adjustment of the angles of the current transformer 6 and the fiber optic temperature measuring device 7 based on the position adjustment. On the one hand, this can solve the problem of alignment between the current transformer 6 and the busbar, thereby ensuring stable power supply and continuous and reliable power supply, providing long-term energy support for the fiber optic temperature measuring device 7. On the other hand, it can easily make the fiber optic temperature measuring device 7 correspond to the temperature measuring point, significantly improving the adaptability of the device to complex installation scenarios.

[0027] Through the above steps, the mounting block 202 is installed via the mounting shaft 201, and the ball joint seat 203 is installed via the mounting block 202, enabling position adjustment of the ball joint seat 203. The mounting plate 204 is then installed via the ball joint seat 203, and the current transformer 6 and the fiber optic temperature measuring device 7 are installed via the two sets of mounting plates 204 respectively. Based on position adjustment, the angles of the current transformer 6 and the fiber optic temperature measuring device 7 can be freely adjusted, effectively solving the alignment problem between the current transformer 6 and the busbar. This addresses the problem that traditional passive wireless temperature measuring devices typically use an integrated structure for the inductive power supply module and the temperature measuring module. Under complex and varied field busbar routing and installation space constraints, the inductive power supply module often cannot achieve precise alignment with the busbar, leading to fluctuations in power extraction efficiency or even power interruption, affecting the normal operation of the temperature measuring module.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
