DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example 1: Please refer to Figure 1-Figure 7 As shown, the utility model provides a technical solution: a weak current intelligent control cabinet with a heat dissipation structure, comprising a device body 1, a cabinet door 2 is hinged on the device body 1, and dustproof nets 3 are arranged at the middle of the top and the left and right side walls of the device body 1, and heat dissipation holes are opened directly below the dustproof net 3, and a mounting frame 4 for mounting electrical components is fixedly connected inside the device body 1;

[0032] The present technical solution sets up the application of a cabinet door 2 and a dustproof net 3. When in use, first place the device body 1 on a flat ground, then turn and open the cabinet door 2, and fix the required electrical components in sequence in the mounting frame 4 to ensure that they are firmly installed and avoid looseness. Further wiring is performed as required to ensure that the lines and electrical components are correctly connected. After the installation is completed, the control cabinet is connected to the power supply and powered on, thereby completing a series of operations.

[0033] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above embodiment 1. The existing heat dissipation effect is poor only through the fan, and the heat dissipation of the fan will be affected by the external environment. When the external temperature is high, it will further affect the heat dissipation effect. Figure 1-Figure 4As shown, a cooling component of a control cabinet is disclosed, wherein a connecting groove 12 is symmetrically arranged on a mounting frame 4, and a heat dissipation pipe 5 is fixedly connected in the mounting frame 4, the water inlet end of the heat dissipation pipe 5 is connected with the water outlet end of a pump 6, and the water inlet end of the pump 6 is connected with a liquid tank 7 through a pipeline, the water outlet end of the heat dissipation pipe 5 is connected with a fixed block 8, and an impeller 9 is rotatably installed in the groove opened in the fixed block 8, a rotating shaft 10 is fixedly connected to the shaft end of the impeller 9, and one end of the rotating shaft 10 away from the impeller 9 extends through the fixed block 8 and is fixedly connected to the fan 11, a heat conducting sheet 13 is fixedly connected in the connecting groove 12, and the heat dissipation pipe 5 is arranged in an "S" shape, and the heat dissipation pipe 5 is made of copper and has good thermal conductivity. The heat conductive sheet 13 is arranged in a copper structure and has good thermal conductivity. The left and right ends of the heat conductive sheet 13 penetrate deeply into the mounting frame 4 and fit with the surface of the heat dissipation pipe 5. The liquid tank 7 is located at the bottom end of the device body 1, and the water inlet end of the liquid tank 7 is connected with the fixed block 8 through a pipeline. The fixed block 8 is symmetrically arranged with two groups about the left and right sides of the device body 1, and the fixed block 8 is connected with the rotating shaft 10 bearing, and the fan 11 on the rotating shaft 10 is rotatably arranged in the heat dissipation holes opened on the left and right side walls of the device body 1.

[0034] In this technical solution, Figure 1 As shown, by using the arrangement of the heat dissipation pipe 5 and the fan 11, when the temperature in the control cabinet is too high, cold water can circulate in the heat dissipation pipe 5 to absorb heat. At the same time, the heat dissipation pipe 5 arranged in an "S" shape can slow down the speed of the water flow, so that the cold water in the heat dissipation pipe 5 can fully absorb heat and dissipate heat efficiently. At the same time, the water flow impacts the impeller 9, which drives the fan 11 to rotate, forming an airflow, so that the air in the device body 1 can circulate, and the hot air is quickly discharged, further improving the heat dissipation efficiency.

[0035] Its use is as Figure 2-Figure 4 The technical solution shown, first, when the temperature of the electrical components inside the control cabinet rises after long-term use, the heat will be conducted to the mounting frame 4 through heat conduction, so that the temperature of the mounting frame 4 rises. At this time, the pump 6 is turned on, so that the pump 6 sucks the water in the liquid tank 7, and the sucked cold water is transported to the heat dissipation pipe 5 in the mounting frame 4. The cold water circulates along the heat dissipation pipe 5 to absorb heat and cool down. At the same time, the cold water in the heat dissipation pipe 5 will flow into the fixed block 8 after absorbing heat, thereby impacting the impeller 9 in the fixed block 8, so that the impeller 9 rotates, and then the impeller 9 will drive the fan 11 to rotate, forming an outward airflow, so that the cold air from the outside enters from the heat dissipation holes above the device body 1, and is discharged through the heat dissipation holes on the side of the device body 1, so that the air in the control cabinet circulates and the hot air is discharged, thereby improving the heat dissipation effect of the device. At the same time, the dustproof net 3 can isolate the dust in the air to prevent dust from entering the interior of the device, and under the action of the drying plate 14, it absorbs moisture in the air to prevent humid water vapor from entering the device body 1.

[0036] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned embodiments 1 and 2. When the external humidity is too high, the dust in the air will stick to the gaps on the dustproof device. After a long period of accumulation, the dustproof device needs to be repaired, which is not convenient for disassembly. In order to further solve this technical problem, this technical solution is as follows: Figure 5-Figure 7 As shown, a quick-release assembly of a control cabinet is disclosed, in which a drying plate 14 is fixedly connected inside a dustproof net 3, a connecting piece 15 is fixedly connected to the outside of the dustproof net 3, a clamping block 16 is fixedly connected to the bottom of the connecting piece 15, and a toggle block 17 is fixedly connected to the clamping block 16, a clamping slot 18 is provided on the device body 1, two connecting pieces 15 are symmetrically arranged about the dustproof net 3, and the size of the connecting piece 15 is consistent with the clamping slot 18, a "convex"-shaped opening is provided at the top of the clamping slot 18, and two clamping slots 18 are symmetrically arranged about the heat dissipation holes, and the protruding part of the clamping slot 18 is consistent with the toggle block 17, the clamping block 16 is a "V"-shaped structure, and the clamping block 16 is elastic.

[0037] In this technical solution, Figure 5 As shown, by utilizing the arrangement of the connecting member 15 and the clamping block 16, during installation, the connecting member 15 and the clamping block 16 are aligned with the clamping slot 18, and the clamping block 16 is slidably inserted into the clamping slot 18. At this time, the clamping block 16 rotates under the action of elastic force and is clamped with the clamping slot 18. The operation is simple, which saves installation time, and is convenient and quick to disassemble, thereby improving maintenance efficiency.

[0038] Its use is as Figure 6 and Figure 7 The technical solution shown in the figure, firstly, when installing the dustproof net 3, align the connecting piece 15 on the side of the dustproof net 3 with the card slot 18 provided on the device body 1, and then press the dustproof net 3 downward, so that the dustproof net 3 drives the card block 16 to slide into the card slot 18 through the connecting piece 15, and then the card slot 18 squeezes the card block 16 to rotate, and when the bottom end of the connecting piece 15 fits with the top end of the card slot 18, the card block 16 is reset and rotated under the action of elastic force, so as to be carded with the card slot 18, so as to achieve quick installation;

[0039] When the dust screen 3 needs to be cleaned, it is only necessary to press the toggle block 17 so that the toggle block 17 squeezes the card block 16, thereby releasing the contact between the card block 16 and the card slot 18, and then pull the dust screen 3 upward to remove the dust screen 3 for cleaning.
