Description

Technical Field

[0001] The utility model relates to the technical field of power supply cabinets, and more specifically, to a top cover of a power supply cabinet. Background Art

[0002] The power cabinet is used to place the control power supply of various circuits and protect the power supply equipment. In actual use, it is an important equipment in the circuit system. The top cover of the power cabinet is generally set separately to meet different usage requirements.

[0003] In order to ensure the stable operation of the internal equipment, a general power cabinet needs to be equipped with a ventilation device to ensure the internal air circulation, so as to dissipate heat and cool down. For this reason, a common power cabinet top cover will open an air vent for air circulation. However, if such a power cabinet is used outdoors, the upper air vent will not only provide air flow, but also rainwater will flow into the power cabinet along the air vent when it rains, which may affect the internal power equipment, causing a short circuit in the power equipment and causing damage. In addition, the common top cover is generally fixed to the cabinet body by fixing bolts. This process requires workers to carry tools to climb to the top of the cabinet body at a high place, and then use tools to tighten multiple bolts to complete the fixing. Whether it is installation and fixing, or reverse disassembly, it is relatively cumbersome and inefficient, which is not conducive to the work of workers. Moreover, the common fixing structures are all set outside the equipment and do not have anti-theft capabilities. The power cabinet set outdoors may be disassembled and sold by people with ulterior motives, causing economic losses, and after losing the protection of the top cover, the power equipment in the cabinet is more easily damaged.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a power cabinet top cover having the following

[0018] Beneficial effects:

[0019] 1. The power cabinet equipment is formed by arranging a cabinet body and a cover body, and the air inflow is ensured through the ventilation cavity, air inlet and fan. By arranging a lower edge frame, the air inlet that should be set on the cover body is set at the lower end of the lower edge frame, so that the air inlet is set downward. When the equipment installed outdoors encounters rainy days, the rainwater will flow downward along the lower edge frame under the guidance of the cover body, and then fall directly to the ground. Even if some rainwater flows along the outer wall of the lower edge frame to the air inlet, it cannot rise along the air inlet into the ventilation cavity, thereby preventing rainwater from entering the cabinet body and ensuring the stability of the power supply equipment in the power cabinet.

[0020] 2. A connection block is provided on the cover body, and a fixing block is provided on the cabinet body to provide a connection structure. A connection and fixing structure is formed by the cooperation of a control block, a clamping ring and a clamping groove. When installing the cover body, it is only necessary to place the cover body on the cabinet body, and then simply rotate the control block and the clamping ring so that the clamping ring cooperates with the clamping groove to fix or disperse the cover body, thereby facilitating the fixation of the cover body, facilitating the operation of workers, and improving work efficiency.

[0021] 3. By arranging the connection block, fixing block, control block, clamping ring and slot on the inner side of the cabinet and the cover, after installing the cover, the connection and fixing structures are hidden inside the power cabinet. When no one is using it, the cabinet door and the cabinet lock are used to seal the cabinet. Unrelated personnel cannot open the cabinet lock without the key, and thus cannot remove the cover, thereby ensuring the safe placement of the power cabinet.

[0022] 4. The fan equipment is supported by setting up an installation frame, and the fan is placed through the installation opening. The fan is limited by the cooperation of the rotating shaft, the support block and the limit plate, so that it is convenient for workers to install the fan. No fixing bolts and other equipment are required. Only the limit plate needs to be moved after the fan is placed, which reduces the amount of operation and facilitates the work of workers.

A fixing block 11 is provided on the cabinet body 1, and a snap groove 12 is opened on the fixing block 11, which cooperates with the snap ring 10.

[0035] In this embodiment, when the device is used, the cover body 2 is installed on the cabinet body 1, covering the upper end of the cabinet body 1. When the fan 3 is working, under the guidance of the fan 3, the external air flow enters the ventilation cavity 4 from the air inlet 7, flows along the ventilation cavity 4, flows out of the ventilation cavity 4 from the air inlet 5, and enters the interior of the cabinet body 1 to carry out the flow of gas. Among them, the air inlet 7 is arranged downward under the structure of the lower edge frame 6. When the material enters the interior of the ventilation cavity 4, it needs to get rid of gravity and go through a rising process, which can effectively prevent rainwater from entering the cabinet body 1 and causing damage to the electronic equipment.

[0036] More specifically, when installing the cover body 2, the cover body 2 is placed on the cabinet body 1 so that the cover body 2 is aligned with the cabinet body 1. Under the fixation of the control block 9, the connecting block 8 is first rotated downward to provide a sufficiently long space for the snap ring 10 to move so that the other end of the snap ring 10 is hooked in the groove 12. Then, the connecting block 8 is rotated so that the connecting block 8 tightens the snap ring 10 so that the snap ring 10 cooperates with the groove 12, and the fixing block 11 is tightened so that the fixing block 11 is tightly attached to the control block 9, thereby fixing the cover body 2 on the cabinet body 1.

[0040] Specifically, a blocking structure is formed in the air inlet 7 by cooperating with the first baffle 15 and the second baffle 16. When the air flow enters the air inlet 7, it will move upward along the flow path formed by the first baffle 15 and the second baffle 16. During this period, rainwater will be blocked by the first baffle 15 and the second baffle 16 and slide down along the first baffle 15 and the second baffle 16.

[0041] Please refer to Figure 2 , Figure 4 and Figure 5As a further implementation of the lower edge frame: a mounting groove 17 is opened at the lower end of the lower edge frame 6, a dustproof frame 18 is arranged in the mounting groove 17, the dustproof frame 18 and the mounting groove 17 are detachably connected by fixing bolts, a dustproof net 19 is arranged in the dustproof frame 18, and the dustproof net 19 cooperates with the air inlet 7.

The fixing bolts are removed to remove the dustproof frame 18 and filter or replace the dustproof net 19.

[0043] Please refer to Figure 3-Figure 5 As a further implementation of the cabinet: a sealing groove 20 is provided at the upper end of the cabinet 1 and the lower end of the cover 2, and a sealing block 21 is provided in the sealing groove 20.

[0044] Specifically, when installing the cover 2, the sealing block 21 is inserted into the sealing groove 20, so that the cabinet 1 and the cover 2 cooperate with the sealing block 21 through the sealing groove 20 to form a sealing structure, ensuring that the cover 2 is stably connected to the cabinet 1 after installation.

[0045] Please refer to Figure 3-Figure 6 As a further implementation of the cover body: a guide rod 22 is provided at the lower end of the cover body 2, a guide groove 23 is opened on the cabinet body 1, and the guide rod 22 and the guide groove 23 are slidably matched.

[0046] Specifically, when installing the cover body 2 , the guide rod 22 is aligned and inserted into the guide groove 23 . Through the cooperation between the guide rod 22 and the guide groove 23 , the guide rod 22 moves along the guide groove 23 to guide the cover body 2 .

[0047] Please refer to Figure 2 and Figure 4 As a further implementation of the cover body: a mounting frame 24 is provided at the lower end of the cover body 2, a mounting opening 25 is provided at one end of the mounting frame 24, and the fan 3 is slidably matched with the mounting opening 25.

[0048] Specifically, after the installation of the cover body 2 is completed, the fan 3 is inserted into the installation frame 24 from the installation opening 25 , and the fan 3 is supported by the installation frame 24 so that the fan 3 cooperates with the air inlet 5 .

[0049] Please refer to Figure 5 As a further implementation of the installation frame: the installation frame 24 is provided with a rotating shaft 26 on both sides of one end of the installation opening 25, and a support block 27 is provided on the lower side. A limiting plate 28 is provided on the rotating shaft 26, and the limiting plate 28 cooperates with the support block 27.

[0050] Specifically, after the fan 3 is installed, the rotating shaft 26 is controlled to rotate, so that the rotating shaft 26 drives the limit plate 28 to rotate, so that the limit plate 28 contacts the support block 27, and the limit plate 28 is supported by the support block 27 to limit the rotation of the limit plate 28. At this time, the limit plate 28 will block the fan 3, limit the fan 3, and ensure the stability of the fan 3.

[0051] In summary, when the overall device is in use or running:

[0052] When installing the cover 2, align the cover 2 with the cabinet 1, align and insert the guide rod 22 into the guide groove 23, and through the cooperation of the guide rod 22 and the guide groove 23, move the guide rod 22 along the guide groove 23 to guide the cover 2 so that the cover 2 accurately fits the cabinet 1. Put the cover 2 on the cabinet 1, and insert the sealing block 21 into the sealing groove 20 when the cover 2 is in contact with the cabinet 1, so that the cabinet 1 and the cover 2 cooperate with the sealing block 21 through the sealing groove 20 to form a sealing structure to ensure that the connection between the cover 2 and the cabinet 1 is stable after installation. Under the fixation of the control block 9, first rotate the connecting block 8 downward to drive the clamping ring 10 to move, so as to provide a sufficiently long activity space for the clamping ring 10 so that the clamping ring 10 can move. The other end of the ring 10 is hooked in the slot 12, and then the connecting block 8 is rotated. The connecting block 8 pulls one end of the snap ring 10 to move, so that the snap ring 10 is stuck in the slot 12, and the snap ring 10 is tightened through the connecting block 8 to make the snap ring 10 cooperate with the slot 12, and tighten the fixing block 11, so that the fixing block 11 is tightly attached to the control block 9, thereby fixing the cover body 2 on the cabinet body 1. In addition, the connecting block 8 and the fixing block 11 are both located inside the cabinet body 1. After the cabinet door 13 is closed, the fixing result of the cover body 2 is hidden inside the cabinet body 1, and the cabinet door 13 is locked by the cabinet lock 14. Non-staff cannot open the cabinet door 13 and cannot contact the connecting and fixing structure of the cover body 2, thereby preventing the cover body 2 from being disassembled from the outside and providing an anti-theft function.

[0053] After the installation of the cover body 2 is completed, the fan 3 is inserted into the installation frame 24 from the installation opening 25, and the fan 3 is supported by the installation frame 24 so that the fan 3 cooperates with the air inlet 5, and the rotating shaft 26 is controlled to rotate, so that the rotating shaft 26 drives the limit plate 28 to rotate, so that the limit plate 28 contacts with the supporting block 27, and the limit plate 28 is supported by the supporting block 27 to limit the rotation of the limit plate 28. At this time, the limit plate 28 will block the fan 3, limit the fan 3, and ensure the stability of the fan 3. In the operation of the power cabinet equipment, when the fan 3 is working, under the guidance of the fan 3, the external air flow enters the ventilation cavity 4 from the air inlet 7, flows along the ventilation cavity 4, flows out of the ventilation cavity 4 from the air inlet 5, and enters the inside of the cabinet 1, so as to circulate the air inside and outside the cabinet 1. Among them, the air inlet 7 is set downward under the structure of the lower edge frame 6, and rainwater will not directly fall into the air inlet 7 from the top or the side. When a substance enters the ventilation cavity 4, it needs to get rid of gravity and go through an ascending process, and the first baffle 15 and the second baffle 16 cooperate to form a blocking structure in the air inlet 7. When the airflow enters the air inlet 7, it will move upward along the flow path formed by the first baffle 15 and the second baffle 16. The rainwater and moisture in the process will be blocked by the first baffle 15 and the second baffle 16, condense in the first baffle 15 and the second baffle 16, and slide down along the first baffle 15 and the second baffle 16, which can effectively prevent rainwater from entering the cabinet 1. In addition, the dustproof frame 18 is installed in the installation groove 17, and the air inlet 7 is blocked by the dustproof net 19 to protect the air inlet 7, and the external dust is intercepted at the outer end of the air inlet 7 to prevent dust and other foreign matter from entering the ventilation cavity 4 with the airflow, thereby preventing rainwater, dust, flying insects and other foreign matter from entering the cabinet 1 and causing damage to electronic equipment.

[0054] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
