Description

Technical Field

[0001] The utility model relates to the technical field of direct current power supply cabinets, in particular to a direct current power supply cabinet with an abnormal alarm function. Background Art

[0002] The working principle of the DC power supply cabinet is based on the modular design of the switching power supply. It adopts the N+1 hot backup mode and has the characteristics of ultra-wide voltage input range and strong grid applicability. The charging module can be plugged in and out with power on, and online maintenance is convenient and fast. In addition, the DC power supply cabinet also has multiple protection functions, such as the insulation detection device combining software and hardware protection to monitor the insulation status of the busbar at any time, and the remote communication function, which can realize centralized monitoring and unmanned operation.

[0003] The existing Chinese patent with publication number CN212626679U discloses a power cabinet with a fault alarm function, which relates to the field of electrical cabinet devices. In view of the problem of hidden arc discharge in the existing power cabinet causing safety hazards, the following scheme is proposed, which includes a shell, a mounting slot is provided in the shell, and the mounting slot runs through one side of the shell, and the shell is provided with a cabinet door at the notch of the mounting slot, and the cabinet door and the mounting slot are matched with each other, and a mounting plate is installed in the mounting slot, and the mounting plate is vertical. After the cabinet door is closed, the light in the mounting slot is blocked by the shell and the cabinet door, and it is in darkness. The mounting plate of the device is used to install the electrical circuit. When the circuit has an arc discharge fault, the arc will generate strong light. Even if it occurs in the electrical components protected by the plastic shell, some light will penetrate the plastic shell. The strong light of the arc discharge will be received by the photoresistor in the photosensor and generate an electrical signal, so that the arc discharge can be recorded and alarmed, so that the staff can repair it in time.

[0004] In view of the above-mentioned related technologies, a photoresistor is used to detect the operation of the parts inside the DC power supply cabinet. During use, the heat generated by the operation of the parts is in the DC power supply cabinet and is dissipated by a fan. However, the heat in the DC power supply cabinet is not dissipated in time, resulting in a deterioration in the operating environment of the parts inside the cabinet, affecting the normal use of the parts. Moreover, if the heat is not dissipated in time under long-term heat accumulation, the fan with a constant speed has a poor heat dissipation effect on the inside of the DC power supply cabinet, affecting the normal use of the power supply cabinet.

[0005] Therefore, we propose a DC power supply cabinet with abnormal alarm function to solve the above problems. Utility Model Content

[0021] 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.

[0022] Example 1: Please refer to Figure 1-4 A DC power supply cabinet with an abnormal alarm function includes a DC power supply cabinet 1, the DC power supply cabinet 1 includes a cabinet body 11 and a slot 113 opened at the side end of the cabinet body 11, a slide slot 114 is opened inside the slot 113 and inside the cabinet body 11, the height of the slide slot 114 is greater than the height of the slot 113, a fan 14 is installed inside the slot 113, and the fan 14 is provided with multiple groups. A blocking member 15 is installed inside the slide slot 114, a heat dissipation hole 111 is opened at the top of the cabinet body 11, a mounting frame 112 is installed inside the heat dissipation hole 111, an alarm 12 is installed at the top of the mounting frame 112, a built-in box 119 is built in the top of the cabinet body 11, a single-chip microcomputer 1191 is installed inside the built-in box 119, and a temperature sensor 1192 is installed outside the built-in box 119. The temperature data detected by the temperature sensor 1192 is controlled by the single-chip microcomputer 1191 to operate the fan 14 to dissipate heat inside the cabinet body 11.

[0023] A position sensor 115 is installed on the inner wall of the slide groove 114 and on one side of the fan 14. A baffle 152 is slidably installed inside the slide groove 114. Limit strips 153 are installed on both sides of the baffle 152. The position sensor 115, the single-chip microcomputer 1191 and the temperature sensor 1192 are electrically connected. A display screen 117 is installed on the outside of the cabinet 11. After the limit strip 153 passes through the slide groove 114, the fan 14 on the side of the position sensor 115 operates.

[0024] In this embodiment: after the temperature sensor 1192 detects the internal temperature of the cabinet 11, the detection temperature range is adjusted through the display screen 117. When the temperature is low, the baffle 152 and the limit bar 153 are inside the slot 113 and the slide 114, the top of the top bar 154 squeezes the rubber strip 118, and the fan 14 does not operate. When the temperature is in the set range and gradually rises, the baffle 152 and the limit bar 153 move down inside the slot 113 and the slide 114. After the limit bar 153 passes through the position sensor 115, the baffle 152 and the limit bar 153 continue to move down, and multiple sets of fans 14 gradually operate along the downward position of the baffle 152. When the temperature is high, the fan 14 operates at the maximum speed to dissipate the heat inside the cabinet 11. When the temperature is too high, the alarm 12 operates to sound an alarm.

[0025] Example 2: Please refer to Figure 1 , Figure 2 and Figure 4 A dustproof net A13 is installed inside the slot 113, and the dustproof net A13 is located on one side of the cylinder 151. A dustproof component 16 is installed on the top of the cabinet 11 and covers the outside of the alarm 12 to prevent dust from entering the cabinet 11.

[0026] The dustproof component 16 includes an installation box 161 and a dustproof net B162 installed at the middle end of the installation box 161. The hot air inside the cabinet 11 is discharged through the heat dissipation holes 111 and the dustproof net B162 for heat dissipation.

[0027] A bottom groove 116 is opened at the bottom end of the slide groove 114 and inside the main body of the cabinet 11 , and a cylinder 151 is installed at the bottom end of the baffle 152 . The cylinder 151 is arranged inside the bottom groove 116 , and the telescopic control of the cylinder 151 controls the baffle 152 to move up and down inside the slide groove 114 .

[0028] A rubber strip 118 is installed at the inner top of the slot 113 and the slide slot 114 , and a top strip 154 ​​is installed at the top of the baffle 152 and the limit strip 153 . The top strip 154 ​​squeezes the rubber strip 118 to prevent the baffle 152 and the limit strip 153 from colliding with the cabinet 11 .

[0029] In this embodiment: when the temperature sensor 1192 detects the internal temperature of the cabinet 11, the cylinder 151 and the fan 14 are operated through the single-chip computer 1191, and the extension and retraction of the cylinder 151 controls the lifting and lowering of the blocking component 15. When the DC power supply cabinet 1 just starts to operate, the generated heat is dissipated through the heat dissipation holes 111 and the dustproof net B162. The dustproof net B162 can ensure that the sound generated when the alarm 12 is in operation can be transmitted, and the dustproof net B162 can prevent dust from being discharged from the heat dissipation holes 111.

[0030] Working principle: With the single chip microcomputer 1191 as the control system, the temperature sensor 1192 first measures the real-time temperature in the cabinet 11, and then transmits the measured temperature to the display screen 117 through data. The display screen 117 sets the temperature range, including the highest temperature and the lowest temperature. After the temperature is set, when the temperature sensor 1192 detects the temperature, when the outside temperature is lower than the minimum value of the set temperature, the fan 14 stops rotating. When the outside temperature is lower than the maximum value of the set temperature, the fan 14 starts to operate. When the outside temperature is above the maximum value of the set temperature, the fan will rotate at full speed.
