Description

Technical Field

[0001] This utility model relates to the field of temperature control components, and in particular to a temperature control component for frequency converter cabinets. Background Technology

[0002] The temperature control components of a variable frequency drive (VFD) cabinet are devices and systems used to monitor and regulate the internal temperature of the cabinet. VFD cabinets are generally used to control the operation of motors, and their internal electronic components generate heat during operation. Excessive heat can affect the performance and lifespan of the equipment, thus requiring effective temperature control. Temperature control components typically include: a temperature sensor (used to monitor the internal temperature of the VFD cabinet in real time, commonly an NTC thermistor or PT100 platinum resistance thermometer); a fan or cooling device (automatically turns on the fan or other cooling equipment to lower the internal temperature when the temperature exceeds a set value); a controller (receives data from the temperature sensor and controls the fan's on / off state according to the set temperature threshold to ensure the internal temperature of the VFD cabinet remains within a safe range); and an alarm system (issues an alarm when the temperature exceeds a preset safe range, alerting operators to the equipment status). Through the coordinated operation of these temperature control components, overheating inside the VFD cabinet can be effectively prevented, improving the stability and reliability of the equipment.

[0003] However, most existing fans are connected and fixed to the frequency converter cabinet with screws during use. Because the internal space of the frequency converter cabinet is limited and the screws on the fan surface are relatively small, the fan is very inconvenient to disassemble. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a temperature control component for frequency converter cabinets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A temperature control component for a frequency converter cabinet includes a base. A connector is slidably connected to one side of the base. Two symmetrically arranged storage slots are formed on the surface of the connector. Each of the two storage slots is equipped with a constraint mechanism for restraining the connector. Four support rods are fixedly connected to the surface of the connector away from the base. The four support rods are evenly arranged in a square shape. Two docking frames are slidably connected to the surface of the four support rods. A fan and a filter plate are fixedly connected to the inside of each of the two docking frames. Four docking slots are formed on one side of each of the two docking frames. Each of the four docking slots is equipped with a constraint mechanism for limiting the docking frames. The docking frames ensure that the fan can be more easily disassembled and maintained.

[0007] As a further embodiment of this utility model, the constraint mechanism includes two first limiting rods, both of which are slidably connected to the top of the base. The top ends of the two first limiting rods are fixedly connected to the same adjusting plate. A pressing plate is fixedly connected to the surface of the adjusting plate near the storage slot. The pressing plate is slidably connected inside the storage slot. A first tension spring is sleeved on the surface of each of the two first limiting rods. The top ends of the two first tension springs are fixedly connected to the bottom of the adjusting plate. The bottom ends of the two first tension springs are fixedly connected to the top of the base. An adjusting mechanism for adjusting the connecting member is provided on the surface of the connecting member near the four support rods. By setting the pressing plate, the connecting member can be constrained.

[0008] As a further embodiment of this utility model, the adjusting mechanism includes a second limiting rod, which is slidably connected to one side of the connecting member. A top plate is fixedly connected to the end of the second limiting rod away from the support rod. A spring is sleeved on the surface of the second limiting rod. One end of the spring is fixedly connected to the inside of the connecting member, and the other end of the spring is fixedly connected to one side of the top plate. By setting the spring, the connecting member can be adjusted so that it can be tightly connected with the extrusion plate.

[0009] As a further embodiment of this utility model, the limiting mechanism includes a connecting box, which is fixedly connected to one side of the connector and slidably connected to the inside of the docking groove. A locking hole is provided at the top of the docking groove, and a second rack is slidably connected inside the locking hole. The second rack is slidably connected inside the connecting box, and a toothed roller is fitted on the surface of the second rack. The toothed roller is rotatably connected inside the connecting box, and a rotating mechanism for rotating the toothed roller is provided on the surface of the toothed roller away from the second rack. By setting the second rack, the docking frame can be limited.

[0010] As a further embodiment of this utility model, the rotating mechanism includes a first rack, which is slidably connected inside the connecting box and is configured to cooperate with the toothed roller. A sliding plate is fixedly connected to the bottom of the first rack, and the sliding plate is configured to cooperate with the extrusion plate. A plurality of second tension springs are fixedly connected to the top of the sliding plate, and the tops of the plurality of second tension springs are all fixedly connected to the inside of the connecting box. The toothed roller can be rotated by the arrangement of the first rack.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model adopts a technical solution of connecting and fixing the fan through an adjusting plate, which ensures that the fan can be more easily disassembled and maintained. This effectively solves the problem that most fans are connected and fixed to the frequency converter cabinet with screws during use. Because the internal space of the frequency converter cabinet is limited and the screw size on the fan surface is relatively small, it is very inconvenient to disassemble the fan. Since the adjusting plate initially constrains the docking frame, and the fan and filter plate are installed inside the docking frame, the connecting parts, fan and filter plate can be removed at the same time after the adjusting plate is pulled into place.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Reference Figure 1 - Figure 6 A temperature control component for a frequency converter cabinet includes a base 1. A connector 2 is slidably connected to one side of the base 1. Two storage slots 201 are symmetrically opened on the surface of the connector 2. Each of the two storage slots 201 is provided with a constraint mechanism for constraining the connector 2. Four support rods 208 are fixedly connected to the surface of the connector 2 away from the base 1. The four support rods 208 are evenly arranged in a square shape. Two docking frames 3 are slidably connected to the surface of the four support rods 208. A fan 303 and a filter plate 304 are fixedly connected to the inside of the two docking frames 3, respectively. Four docking slots 301 are opened on one side of each of the two docking frames 3. The docking slots 301 can ensure that the docking frames 3 can be connected to the connector 2. Each of the four docking slots 301 is provided with a constraint mechanism for limiting the docking frames 3. The docking frames 3 can ensure that the fan 303 can be more easily disassembled and maintained.

[0023] Preferably, the constraint mechanism includes two first limiting rods 102, both of which are slidably connected to the top of the base 1. The top ends of the two first limiting rods 102 are fixedly connected to the same adjusting plate 101. A pressing plate 104 is fixedly connected to the surface of the adjusting plate 101 near the storage groove 201. The pressing plate 104 is slidably connected inside the storage groove 201. A first tension spring 103 is sleeved on the surface of each of the two first limiting rods 102. The pressing plate 104 can be reset by the setting of the first tension spring 103. The top ends of the two first tension springs 103 are fixedly connected to the bottom of the adjusting plate 101. The bottom ends of the two first tension springs 103 are fixedly connected to the top of the base 1. The surface of the connector 2 near the four support rods 208 is provided with an adjusting mechanism for adjusting the connector 2. The connector 2 can be constrained by the setting of the pressing plate 104.

[0024] Furthermore, the adjustment mechanism includes a second limiting rod 209, which is slidably connected to one side of the connector 2. A top plate 210 is fixedly connected to the end of the second limiting rod 209 away from the support rod 208. A spring 211 is sleeved on the surface of the second limiting rod 209. One end of the spring 211 is fixedly connected to the inside of the connector 2, and the other end of the spring 211 is fixedly connected to one side of the top plate 210. By setting the spring 211, the connector 2 can be adjusted so that it can be tightly connected with the extrusion plate 104.

[0025] Preferably, the limiting mechanism includes a connecting box 202, which is fixedly connected to one side of the connector 2 and slidably connected to the inside of the docking groove 301. A locking hole 302 is provided at the top of the docking groove 301, and a second rack 207 is slidably connected inside the locking hole 302. The second rack 207 is slidably connected inside the connecting box 202. By setting the locking hole 302, the docking frame 3 can be connected to the second rack 207. A toothed roller 205 is fitted on the surface of the second rack 207. The toothed roller 205 is rotatably connected inside the connecting box 202. A rotating mechanism for rotating the toothed roller 205 is provided on the side of the toothed roller 205 away from the second rack 207. By setting the second rack 207, the docking frame 3 can be limited.

[0026] Furthermore, the rotating mechanism includes a first rack 206, which is slidably connected inside the connecting box 202 and is configured to cooperate with the toothed roller 205. A slide plate 203 is fixedly connected to the bottom of the first rack 206, and the slide plate 203 is configured to cooperate with the extrusion plate 104. Multiple second tension springs 204 are fixedly connected to the top of the slide plate 203. The slide plate 203 can be reset by the second tension springs 204. The tops of the multiple second tension springs 204 are all fixedly connected inside the connecting box 202. The toothed roller 205 can be rotated by the first rack 206.

[0027] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the fan 303 needs to be inspected and maintained, the two adjusting plates 101 on the surface of the base 1 are first pulled. A connector 2 is installed on one side of the base 1, and two storage slots 201 are opened on the surface of the connector 2. The adjusting plate 101 is initially inside the storage slot 201, thereby ensuring that the connector 2 can be tightly connected to the base 1. A sliding plate 203 is also installed inside the storage slot 201, and the sliding plate 203 is connected to the connector 2 through a second tension spring 204. The sliding plate 203 also cooperates with the adjusting plate 101. Therefore, when the adjusting plate 101 is pulled, the sliding plate 203 will be reset under the action of the second tension spring 204. A plate is installed on the top of the sliding plate 203. There is a first rack 206, which cooperates with the toothed roller 205. When the slide plate 203 moves the first rack 206 upward, the toothed roller 205 will rotate synchronously. A second rack 207 is installed at the other end of the toothed roller 205. The second rack 207 and the first rack 206 are centrally symmetrical. So when the first rack 206 moves upward, the toothed roller 205 moves the second rack 207 downward. Since the second rack 207 is initially inside the docking frame 3, when the second rack 207 moves downward, the constraint on the docking frame 3 is released. The fan 303 and the filter plate 304 are both installed inside the docking frame 3. So when the adjusting plate 101 is pulled into place, the connector 2, the fan 303, and the filter plate 304 can be removed at the same time.
