Description

Technical Field

[0001] The present invention relates to the technical field of installation cabinets, and particularly to a variable-frequency cabinet device. Background Art

[0002] During the use of a variable-frequency cabinet device, a large amount of heat is generated inside, resulting in a very high temperature inside the variable-frequency cabinet device. It is necessary to dissipate heat in time, otherwise it will cause overheating of electronic components, aging of circuits and even fire, seriously affecting the service life of the variable-frequency cabinet device. At the same time, the variable-frequency cabinet device also needs to have good sealing conditions to prevent water leakage from the pipes above the variable-frequency cabinet device from entering the inside of the variable-frequency cabinet device and causing a short circuit of the circuit. In practical applications, a waterproof iron boron provided on the top of the variable-frequency cabinet device is used for waterproofing. However, in the case of no water leakage, the use of the waterproof device shed affects the heat dissipation effect of the variable-frequency cabinet device and affects the aesthetics. Especially when the weather is hot, it is also necessary to cool it by moving a fan, which occupies a large space and there are also some safety hazards. In addition, the variable-frequency cabinet device in the prior art also has the problem of difficult movement. When using other tools to move it, the variable-frequency cabinet device is easy to fall, resulting in damage to the cabinet and casualties. Summary of the Invention

[0003] To solve the technical problems in the background art, the present invention proposes a variable-frequency cabinet device.

[0004] The variable-frequency cabinet device includes: a cabinet body that can accommodate an inverter, an air intake mechanism, an air exhaust mechanism, and a waterproof mechanism. The air intake mechanism includes an air intake opening opened on the cabinet body and an air intake fan provided at the air intake opening. The air exhaust mechanism includes a first air exhaust opening opened on the cabinet body and a first air exhaust fan provided at the first air exhaust opening. The waterproof mechanism includes a waterproof part, a support part, and a locking and releasing part. The support part is connected to the cabinet body, and the locking and releasing part is connected between the support part and the waterproof part. When the locking and releasing part is in the locked state, the waterproof part covering the upper and surrounding parts of the air intake mechanism and the air exhaust mechanism can be fixedly locked on the support part. When the locking and releasing part is in the released state, the waterproof part can be removed from the support part.

[0005] Preferably, the locking and releasing part includes a locking and releasing part body and a buckle. The locking and releasing part body is fixedly connected to the support part. The locking and releasing part body has a card slot with an elastically variable diameter. The buckle is fixedly connected to the waterproof part. The buckle includes a card head that can be adaptively inserted into the card slot and is fixedly buckled in the card slot by a certain elastic force of the card slot.

[0006] Preferably, the air exhaust mechanism further includes a second air exhaust opening and a second air exhaust fan. The cabinet body includes a cabinet body main body and a cabinet door for closing and opening the cabinet body main body. The air intake mechanism is located at the bottom of the cabinet door. The first air exhaust opening and the first air exhaust fan, and the second air exhaust opening and the second air exhaust fan are respectively located at the tops of the two sides of the cabinet body main body perpendicular to the cabinet door.

[0007] Preferably, the induced draft fan, the first exhaust fan, and the second exhaust fan are all axial flow fans.

[0008] Preferably, the frequency conversion cabinet device further includes a first hollow baffle, a second hollow baffle, and a third hollow baffle that are installed on the outer wall of the cabinet and are respectively located at the positions of the induced draft fan, the first exhaust fan, and the second exhaust fan.

[0009] Preferably, the frequency conversion cabinet device further includes a traveling mechanism, and the traveling mechanism includes a plurality of universal wheels, and the universal wheels are connected to the bottom surface of the cabinet body.

[0010] Preferably, the frequency conversion cabinet device further includes a braking mechanism, and the braking mechanism includes a brake pad, and the brake pad is hinged to the traveling mechanism. When the brake pad rotates to a position where it presses against the surface of the universal wheel, the universal wheel stops moving.

[0011] Preferably, the frequency conversion cabinet device further includes a handle, and the handle is installed on the outer wall of the cabinet body.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The locking and releasing part can achieve the quick fastening of the waterproof part on the supporting part. At the same time, since the waterproof part is only arranged above and around the air induction mechanism and the exhaust mechanism, the air induction mechanism can still introduce the cold air from the outside into the cabinet through its lower part, and at the same time, the exhaust mechanism can still discharge the hot air in the cabinet to the outside of the cabinet through its lower part. Thus, heat dissipation is achieved while ensuring waterproofing. In addition, when there is no longer a risk of water ingress, the locking and releasing part can be set to the release state, and the waterproof part can be removed from the supporting part to more reliably ensure the heat dissipation effect of the frequency conversion cabinet device.

[0014] The first exhaust air outlet, the first exhaust fan, the second exhaust air outlet, and the second exhaust fan can ensure that the hot air in the cabinet is discharged from the cabinet in time, further ensuring the heat dissipation effect of the frequency conversion cabinet device.

[0015] The traveling mechanism, the braking mechanism, and the handle make the movement of the frequency conversion cabinet device more labor-saving, convenient, and safe. Description of the Drawings

[0022] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Refer to Figures 1 to 6 , the variable-frequency cabinet device includes: a cabinet body 1 that can accommodate a frequency converter, an air intake mechanism 2, an air exhaust mechanism 3, and a waterproof mechanism 4. The air intake mechanism 2 includes an air intake opening 21 formed on the cabinet body 1 and an air intake fan 22 arranged at the air intake opening 21. The air exhaust mechanism 3 includes a first air exhaust opening 31 formed on the cabinet body 1 and a first air exhaust fan 32 arranged at the first air exhaust opening 31. The waterproof mechanism 4 includes a waterproof part 41, a support part 42, and a locking and releasing part. The support part 42 is connected to the cabinet body 1, and the locking and releasing part is connected between the support part 42 and the waterproof part 41. When the locking and releasing part is in the locked state, the waterproof part 41 covering the upper part and the periphery of the air intake mechanism 2 and the air exhaust mechanism 3 can be fixedly locked on the support part 42, thereby effectively preventing water leakage from pipes or rainwater, etc. from entering the interior of the variable-frequency cabinet device. At the same time, since the waterproof part 41 is not provided below the air intake mechanism 2 and the air exhaust mechanism 3, the air intake mechanism 2 can still introduce cold air from the outside into the cabinet body 1 through its lower part, and the air exhaust mechanism 3 can still discharge the hot air in the cabinet body 1 to the outside of the cabinet body 1 through its lower part, so that heat dissipation is achieved while waterproofing. In addition, when there is no longer a risk of water ingress, the locking and releasing part can be operated to the released state to remove the waterproof part 41 from the support part 42 to more reliably ensure the heat dissipation effect of the variable-frequency cabinet device.

[0024] Refer to Figures 3 to 6 , the locking and releasing part includes a locking and releasing part body 431 and a buckle part 432. The locking and releasing part body 431 is fixedly connected to the support part 42. The locking and releasing part body 431 has a clamping groove 4311 with an elastically variable diameter. In this embodiment, the elastic change of its diameter is realized by arranging elastically telescopic steel balls 4312 on both sides of the clamping groove 4311. The steel balls can slide in the sliding groove 4313, and a spring 4314 is arranged in the sliding groove 4313. The locking and releasing part body 431 is bolted to the support part 42 through through holes 4315 at both ends. The buckle part 432 is fixedly connected to the waterproof part 41. In this embodiment, it can be bonded or sewn to the waterproof part 41 through through holes 4322 at both ends of the buckle part 432. In this embodiment, the waterproof part 41 is made of a soft and foldable waterproof cloth. The buckle part 432 includes a clamping head 4321 that can be adaptively inserted into the clamping groove 4311 and is clamped and fixed in the clamping groove 4311 by a certain elastic force.

[0025] When the waterproof part 41 needs to be used, simply snap the chuck 4321 on the snap member 432 into the slot 4311 of the locking and releasing part body 431 to fix the waterproof part 41. When the waterproof part 41 needs to be removed, just apply force to pull out the chuck 4321 outward, thus realizing the quick installation and removal of the waterproof part 41.

[0026] Refer to Figure 1 and Figure 2 The exhaust mechanism 3 further includes a second exhaust port 33 and a second exhaust fan 34. The cabinet 1 includes a cabinet body 11 and a cabinet door 12 for closing and opening the cabinet body 11. The air guiding mechanism 2 is located at the bottom of the cabinet door 12, and the first exhaust port 31 and the first exhaust fan 32, the second exhaust port 33 and the second exhaust fan 34 are respectively located at the tops of the two sides of the cabinet body 11 perpendicular to the cabinet door 12.

[0027] Cold air flows into the cabinet 1 from the lower air inlet 21. The frequency converter works to heat up the air inside the cabinet 1. The hot air moves upward and is discharged from the first exhaust port 31 and the second exhaust port 33 located above the air inlet 21. By virtue of the movement characteristics of the hot air, it is beneficial to form natural convection of the air. At the same time, the two exhaust ports ensure the timely discharge of the hot air inside the cabinet 1, thus ensuring the heat dissipation effect.

[0028] The air guiding fan 22, the first exhaust fan 32, and the second exhaust fan 34 are all axial fans. Axial fans can, while meeting the requirements of air flow, be more easily installed on the frequency conversion cabinet device, and at the same time, the structure is more compact and more energy-saving during use.

[0029] It further includes a first hollow baffle 23, a second hollow baffle 35, and a third hollow baffle 36 respectively installed on the outer wall of the cabinet 1 at the positions of the air guiding fan 22, the first exhaust fan 32, and the second exhaust fan 34 to prevent foreign objects from entering and ensure the working reliability of the frequency conversion cabinet device.

[0030] Refer to Figure 1 , Figure 2 The frequency conversion cabinet device further includes a traveling mechanism 5. The traveling mechanism 5 includes a plurality of universal wheels connected to the bottom surface of the cabinet 1, and the traveling mechanism 5 makes the movement of the frequency conversion cabinet device more labor-saving and safe.

[0031] The frequency conversion cabinet device further includes a braking mechanism. The braking mechanism includes a brake pad 6. The brake pad 6 is hinged to the traveling mechanism 5. When the brake pad 6 rotates to a position where it presses against the surface of the universal wheel, the universal wheel stops moving to improve the use safety of the frequency conversion cabinet device.

[0032] Refer to Figure 1, the variable frequency cabinet device further includes a handle 7, and the handle 7 is installed on the outer wall of the cabinet body 1, which is convenient for the operator to grasp and find the force application point to push the variable frequency cabinet device.
