Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of variable frequency cabinet detection, and particularly relates to a temperature and humidity monitoring device configured in a variable frequency cabinet. BACKGROUND

[0002] In recent years, high copper prices have stimulated the rapid rise of global copper production capacity, and new copper smelters have emerged, corresponding to which copper processing fees have been increasingly reduced, and profits have become increasingly thin. Many new copper smelters use the flash smelting, flash converting (i.e., "double flash") copper concentrate smelting process, which is one of the most advanced technologies in the world today, to improve automation and take the road of scale to increase enterprise profits.

[0003] However, large-scale factories often lead to power supply shortages and other situations, such as the "double flash" copper smelter configuration method disclosed in the Chinese patent with the application number CN201210427685.9, so it is often necessary to configure a corresponding detection device to detect the operating state of the variable frequency cabinet. However, the existing copper double flash smelter can only obtain traditional frequency converter operating parameters when using the detection device to detect the operating state of the variable frequency cabinet, and cannot further collect the operating state data that users are most concerned about in actual operation.

[0004] At this time, the temperature and humidity monitoring device configured in the variable frequency cabinet can be used to upload data in a communication manner to solve the above technical problems. However, since the traditional wireless sensor is generally installed in the variable frequency cabinet, the temperature inside the variable frequency cabinet is high when it is working, which can easily damage the sensor. Therefore, the wireless temperature sensor needs to be detected and replaced every certain period of time.

[0043] ​​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0044] In the embodiments, refer to Figures 1 to 10 .

[0045] As Figure 1 described, the present application provides a temperature and humidity monitoring device configured in a variable frequency cabinet, which comprises a communication mechanism 2 located in the variable frequency cabinet and a sensing assembly 3 installed on the interface terminal 1 of the variable frequency cabinet. The sensing assembly 3 uses wireless signals to transmit data to the outside through the communication mechanism 2.

[0046] Therefore, the temperature and humidity monitoring device configured in the variable frequency cabinet can sense the temperature and humidity of the interface terminal 1 of the variable frequency cabinet and upload data in a communication mode using the communication mechanism 2.

[0047] As shown in Figure 2 and Figure 3 , the sensing assembly 3 comprises an outer frame structure 31, an inner frame structure 32, a sensor mounting structure 33, a cable tie fixing assembly 34 and a wireless sensor structure 36 for monitoring the temperature and humidity of the interface terminal 1 of the variable frequency cabinet, wherein:

[0048] The inner frame structure 32 slides inside the outer frame structure 31 and clamps the interface terminal 1 of the variable frequency cabinet in cooperation with the outer frame structure 31 and the cable tie fixing assembly 34 installed on the inner frame structure 32. The inner frame structure 32 is provided with a sensor mounting structure 33 for mounting and fixing the wireless sensor structure 36.

[0049] At this time, in the state that the inner frame structure 32 clamps the interface terminal 1 of the variable frequency cabinet in cooperation with the outer frame structure 31, the wireless sensor structure 36 is in contact with the interface terminal 1 of the variable frequency cabinet and monitors the temperature and humidity.

[0050] Specifically, the outer frame structure 31 and the inner frame structure 32 are arranged in a sleeve structure by sliding up and down, which can form a double-frame structure, well hiding the wireless sensor structure 36 and playing a role of theft prevention.

[0051] Further, in a specific embodiment, as Figure 4As shown, the outer frame structure 31 has a frame sliding groove 314 on its side wall for limiting the sliding of the inner frame structure 32 in the vertical direction. The bottom of the outer frame structure 31 is provided with a mounting base plate 311 for mounting an arc-shaped rubber pad 312. The arc-shaped rubber pad 312 is also provided with a deformable sponge 313 for cooperating with the inner frame structure 32 to clamp the inverter cabinet interface terminals 1 of different outer diameters.

[0052] It should be noted that the arc-shaped rubber pad 312 here is used to support the deformation sponge 313. The deformation sponge 313 can adapt to contacting the inverter cabinet interface terminals 1 with different outer diameters. The deformation sponge 313 here can be made of sponge ceramic material.

[0053] In practice, the outer frame structure 31 and the inner frame structure 32, together with the cable tie fixing component 34, can be used to facilitate the overall stable alignment and installation of the device on cable joints of different outer diameters.

[0054] Further, in one specific embodiment, such as Figure 5 As shown, the inner frame structure 32 has an insulating shell 321 with a bottom opening installed on the inner side by adjusting bolts 324. The insulating shell 321 is provided with a handle 322 and a signal transmission module 323.

[0055] At this time, combine Figure 8 and Figure 9 It can be seen that the sensor mounting structure 33 is set inside the insulating housing 321 for mounting the wireless sensor structure 36, and the signal transmission module 323 and the wireless sensor structure 36 are connected through the sensor plug-in 325 set inside the insulating housing 321.

[0056] Specifically, the sensor mounting structure 33 includes a limiting block groove 339 formed on the inner wall of the insulating housing 321, a triangular limiting block 338 disposed in the limiting block groove 339 for limiting the wireless sensor structure 36 mounted in the insulating housing 321, a connecting pull rope 335 disposed at one end on the triangular limiting block 338, a magnetic metal block 333 disposed at the other end of the connecting pull rope 335, and a metal block sliding groove 334 disposed inside the insulating housing 321 for accommodating the magnetic metal block 333 to slide. The supporting wheel 336 is rotatably disposed inside the insulating shell 321 and in contact with the connecting pull rope 335 to change the direction of movement of the connecting pull rope 335; the electromagnet 331 is disposed in the metal block sliding groove 334 to electromagnetically drive the magnetically attracted metal block 333 to move closer when energized; the energizing terminal 332 is disposed at the bottom of the insulating shell 321 for energizing the electromagnet 331; and the compression spring 337 is disposed in the limiting block sliding groove 339 and connected at both ends to the inner wall of the limiting block sliding groove 339 and the triangular limiting block 338 respectively.

[0057] At this time, it needs to be explained that the outer frame structure 31 is provided with a hidden groove 315 for accommodating the power terminal 332 in the state that the inner frame structure 32 cooperates with the outer frame structure 31 to clamp the interface terminal 1 of the frequency conversion cabinet.

[0058] In addition, it needs to be explained that the wireless sensor structure 36 is composed of a sensor body and an external connecting frame, and the sensor body here is a prior art, which can refer to the sensor body used in the existing patent with the application number CN202310496224.5: a wireless temperature measurement sensor for power distribution cabinet.

[0059] The outer connecting frame of the wireless sensor structure 36 is also provided with a shell clamping groove 361 on the side wall for sliding insertion of the triangular limiting block 338, and the outer connecting frame of the wireless sensor structure 36 is also provided with a sensor interface 362 for insertion connection of the sensor plug-in 325 to transmit the detection data of the wireless sensor structure 36 to the communication mechanism 2 through the signal transmission module 323.

[0060] When installing the wireless sensor structure 36, the wireless sensor structure 36 enters from the lower opening of the insulating shell 321, at this time the outer connecting frame of the wireless sensor structure 36 can push the triangular limiting block 338 to slide in the limiting block sliding groove 339 and control the extrusion of the extrusion spring 337, when the wireless sensor structure 36 is installed and moved to a certain distance position, the extrusion spring 337 pushes the triangular limiting block 338 into the shell clamping groove 361 to complete the clamping installation of the wireless sensor structure 36 at the bottom of the insulating shell 321.

[0061] When disassembling the wireless sensor structure 36, the power terminal 332 at the bottom of the insulating shell 321 is used to connect the power, which can control the electromagnet 331 to generate magnetic force to drive and move the magnetic metal block 333, so as to separate and pull out the triangular limiting block 338 from the limiting block sliding groove 339, cooperate with the downward spring 326 and the connecting spring plate 327 to quickly pop out the wireless sensor structure 36, and quickly disassemble and replace the temperature and humidity sensor, which is convenient to use.

[0062] It needs to be noted that the connection of the electromagnet 331 with the power terminal 332 and the generation of magnetic force by the electromagnet 331 belong to the prior art, so the working principle is not described here.

[0063] It needs to be further explained here that, as shown in Figure 9 The inner frame structure 32 is also provided with a spring plate sliding groove 328 at the opening, the connecting spring plate 327 is vertically slidingly arranged in the spring plate sliding groove 328, the downward spring 326 is arranged in the spring plate sliding groove 328 and connected with the connecting spring plate 327 for driving the connecting spring plate 327 to move downward under stress, and the sliding insertion hole 329 is arranged on the connecting spring plate 327 for sliding insertion of the sensor plug-in 325.

[0064] In addition, as shown in Figure 10 the inside of the sliding hole 329 is distributed with a plurality of dustproof rubber cloth 3291 for sensor plug-in 325 and sliding hole 329 in the state of separation cover sliding hole 329, can be in the sensing assembly 3 is not used when the effect of the sensor plug-in 325 dustproof, to ensure that the sensing assembly 3 as the interface structure of the sensor plug-in 325 can be used normally, not easy to damage, with a very high number of plug, long service life.

[0065] Further in a specific embodiment, as shown in Figure 6 and Figure 7 the side wall of the insulating shell 321 is provided with a strap fixing assembly 34 for fixing the inner frame structure 32 and the outer frame structure 31 in the connected state during the clamping of the frequency conversion cabinet interface terminal 1, the strap fixing assembly 34 includes a strap mounting block 342 provided on the side wall of the insulating shell 321, a parallel serrated strap 341 provided on the strap mounting block 342, an L-shaped through hole 343 provided on the strap mounting block 342 for the parallel serrated strap 341 to pass through, a limiting sliding groove 344 provided in the strap mounting block 342, at least two groups of limiting sliding blocks 345 slidingly arranged in the limiting sliding groove 344, a connecting shaft 346 for fixing the limiting sliding blocks 345 and extending to the outside of the strap mounting block 342, a contact pressure plate 347 provided on one end of the connecting shaft 346 outside the strap mounting block 342, a connecting spring 348 provided in the limiting sliding groove 344 for contacting one group of limiting sliding blocks 345, and a strap tooth 349 provided at the bottom of the limiting sliding block 345 for engaging with the serrations of the parallel serrated strap 341 to fix the parallel serrated strap 341.

[0066] It should be noted that the parallel serrated strap 341 here can refer to the strap structure shown in Figure 5 and Figure 6 The strap structure is composed of a strap body and at least two parallel serrations provided on the strap body.

[0067] In the normal state, the connecting spring 348 drives the limiting sliding block 345 and the connecting shaft 346 to move outwardly from the insulating shell 321, and at this time the connecting shaft 346 extends out of the insulating shell 321;

[0068] By pressing the contact pressure plate 347, the limiting sliding block 345 and the connecting shaft 346 can be moved within the insulating shell 321, at this time the parallel serrated strap 341 can normally pass through the L-shaped through hole 343, and at this time the serrations of the parallel serrated strap 341 are out of position and do not contact the strap teeth 349 at the bottom of the limiting sliding block 345, the parallel serrated strap 341 is in a non-fixed state and can be slid at will;

[0069] When the parallel sawtooth cable tie 341 passes through the L-shaped through hole 343 to the inner frame structure 32 and the outer frame structure 31 matched clamping variable frequency cabinet interface terminal 1 and uses wireless sensor structure 36 to inductively detect the terminal, loosen the contact pressing plate 347, the connecting spring 348 drives the limiting sliding block 345 and the connecting shaft 346 to move, and the cable tie catch 349 can be engaged between the sawteeth of the parallel sawtooth cable tie 341, the sawteeth of the parallel sawtooth cable tie 341 are moved and limited, so that the connection and fixation of the parallel sawtooth cable tie 341 are completed, and the parallel sawtooth cable tie 341 is in a fixed state.

[0070] In addition, a closed gas control assembly 35 for controlling the sealing of the inside of the insulating shell 321 in which the wireless sensor structure 36 is installed is further arranged between the insulating shell 321 and the cable tie mounting block 342 in the non-fixed state of the parallel sawtooth cable tie 341. The closed gas control assembly 35 includes a sliding rail 351 arranged on the side wall of the insulating shell 321 along the extension direction of the connecting shaft 346, a plurality of closed gas holes 352 opened in the side wall of the insulating shell 321 for communication to the inside of the insulating shell 321, a sliding baffle 353 sliding on the sliding rail 351, a connecting clamping plate 354 arranged on the sliding baffle 353, a U-shaped port connecting bracket 355 arranged on a group of limiting sliding blocks 345 for sliding installation at the end of the connecting clamping plate 354, and a bracket sliding slot 356 arranged on the cable tie mounting block 342 and in communication with the limiting sliding groove 344 for limiting sliding of the U-shaped port connecting bracket 355.

[0071] When the parallel sawtooth cable tie 341 passes through the L-shaped through hole 343 and is in a non-fixed state, the limiting sliding block 345 drives the sliding baffle 353 to move to expose the closed gas hole 352 through the U-shaped port connecting bracket 355 and the connecting clamping plate 354. At this time, the inside of the insulating shell 321 is ventilated, and the dismounting and mounting work of the wireless sensor structure 36 can be carried out;

[0072] When the parallel sawtooth cable tie 341 passes through the L-shaped through hole 343 and is in a fixed state, the limiting sliding block 345 drives the sliding baffle 353 to move to cover the closed gas hole 352 through the U-shaped port connecting bracket 355 and the connecting clamping plate 354. At this time, the inside of the insulating shell 321 is sealed. Since the air pressure inside the insulating shell 321 can control the wireless sensor structure 36 to always engage inside the insulating shell 321, dismounting cannot be carried out at this time. Similarly, when the wireless sensor structure 36 is installed, the inside of the insulating shell 321 is relatively closed, and the wireless sensor structure 36 cannot normally enter the inside of the insulating shell 321 to complete the installation.

[0073] Therefore, by setting the air closing control assembly 35, when the wireless sensor structure 36 is installed and dismounted inside the insulating shell 321, the installation and dismounting of the wireless sensor structure 36 in the parallel sawtooth ribbon 341 loosening adjustment state can be avoided, the wireless sensor structure 36 is easily damaged when the connected frequency conversion cabinet interface terminal 1 is vertically arranged, the wireless sensor structure 36 can be further protected to ensure the normal installation and dismounting of the wireless sensor structure 36, and the secondary protection effect is achieved.

[0074] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.

[0075] In addition, it needs to be explained that if the embodiment of the present application involves directional indication (such as up, down, left, right, front, back, etc.), the directional indication is only used to explain the relative position relationship, motion condition, etc. between components in a certain posture, and if the certain posture changes, the directional indication also changes accordingly.
