[0029] The embodiments of the present application will be described below according to the overall structure of the present application. Embodiment one:
[0030] A precise isolation power supply with good safety protection performance, as shown in Figures 1-4 , comprising a main body 1, a shell 2 and a protection mechanism 6, the protection mechanism 6 comprises a wiring port 601, the outer surface of the wiring port 601 is provided with a limiting ring 602, one side of the limiting ring 602 is provided with a ratchet wheel 607, the outer side of the ratchet wheel 607 is provided with a winding coil 603, the inner wall of the winding coil 603 is provided with a pawl 608, one side of the winding coil 603 is provided with a magnetic attraction ring 604, the inner wall of the wiring port 601 is provided with a wire passing pipe 609, one end of the wiring port 601 is provided with an insulating cloth 605, one side of the insulating cloth 605 is provided with a tightening port 606, the wiring port 601 is used as a connection point of the power supply and the external cable, which ensures that the cable can be stably and safely connected to the power supply, the winding coil 603 can rotate around the wiring port 601, and the pawl 608 on the inner wall thereof cooperates with the ratchet wheel 607 to realize the fastening of the cable by the tightening port 606.
[0031] Referring to Figure 1 , Figure 2There are two protective mechanisms 6, which are mirror images of each other along the central axis of the main body 1. The mirror images of the protective mechanisms 6 make the internal components of the power supply easier to access, facilitate the connection of external cables, and make it easier for operators to install and maintain the power supply. The two protective mechanisms 6 are respectively located at the input end and the output end, forming a double isolation barrier to ensure that the power supply can work stably and safely when receiving electrical energy.
[0032] The implementation principle of this utility model is as follows: First, the connecting wire inside the tightening port 606 is passed through the conduit 609 and fixedly connected to the winding coil 603. Then, the external cable is connected to the power supply through the connection port 601. Rotating the winding coil 603 causes it to pull the connecting wire inside the tightening port 606, thus pressing the external cable against the tightening port 606. The ratchet 607 and pawl 608 prevent the winding coil 603 from rotating back. When it is necessary to disconnect the cable, the magnetic ring 604 can be removed along the connection port 601. Then, the winding coil 603 is pulled out, causing the ratchet 607 and pawl 608 to be misaligned and the tightening port 606 to open. After that, the cable can be pulled out and the winding coil 603 and magnetic ring 604 can be reinstalled in sequence. Example 2:
[0033] See Figure 1 , Figure 3 The top of the casing 2 is provided with an air outlet grille 3 and the bottom of the casing 2 is provided with an air inlet grille 9. The air outlet grille 3 located at the top of the casing 2 provides an effective exhaust channel for hot air inside the power supply, preventing heat from accumulating inside the power supply. The combination of the air outlet grille 3 and the air inlet grille 9 promotes air circulation inside the power supply, enabling the power supply to continuously and effectively dissipate heat.
[0034] See Figure 2 A fixing plate 7 is provided above the air intake grille 9. The outer surface of the fixing plate 7 has ventilation holes 8. The ventilation holes 8 on the outer surface of the fixing plate 7 provide an air circulation channel for the inside of the power supply, so that the air is more evenly distributed inside the power supply, avoiding the occurrence of local overheating, improving the uniformity and efficiency of heat dissipation. The fixing plate 7 supports and enhances the structural stability of the power supply, and can effectively resist external impacts and vibrations, protecting the internal components of the power supply from damage.
[0035] See Figure 3 Below the air intake grille 9 is a base plate 10, and at the bottom of the base plate 10 is a fan air intake 11. At the top of the fan air intake 11 is a fan 12. The air intake grille 9 is located on the air intake side of the power supply casing, and its lower part is close to the base plate 10, ensuring that external cold air can smoothly enter the power supply through the air intake grille 9. The fan 12 is located at the top of the fan air intake 11 and generates forced convection by rotating, which quickly removes the heat inside the power supply.
[0036] See Figure 3The inner wall of the shell 2 is provided with a micro dust sensor 4, one side of the micro dust sensor 4 is provided with a temperature sensor 5, and the micro dust sensor 4 arranged on the inner wall of the shell 2 can monitor the dust content in the air inside the power supply in real time, and the temperature sensor 5 is responsible for monitoring the working temperature of the power supply, so that the power supply can work in a safe temperature range.
[0037] Refer to Figure 3 The model of the micro dust sensor 4 is S7 Smart Dust, and the model of the temperature sensor 5 is FT-H20; the S7 Smart Dust micro dust sensor 4 has high-precision monitoring capability and can accurately detect tiny dust particles in the air, so that the dust pollution in the working environment of the power supply can be monitored in real time and accurately; and the FT-H20 temperature sensor 5 has a wide temperature measurement range and good stability, and can adapt to temperature changes in different working environments.
[0038] The implementation principle of the utility model is as follows: firstly, when the power supply works, the fan 12 rotates to make the air pass through the air inlet grille 9, the ventilation hole 8, the temperature sensor 5, the micro dust sensor 4 and the air outlet grille 3 in sequence from the fan air inlet 11; the temperature sensor 5 detects the outlet temperature in real time and feeds back to the external control console through an electric signal; the external control console adjusts the rotating speed of the fan 12 according to the temperature, and when the temperature reaches a threshold value, the temperature sensor 5 feeds back to the external control console through an electric signal to alarm the operator to stop and overhaul; the micro dust sensor 4 detects the dust content of the outlet air in real time, and when the dust concentration reaches a threshold value, the micro dust sensor 4 feeds back to the external control console through an electric signal to inform the operator to clean the air inlet grille 9, the air outlet grille 3 and the fan air inlet 11.
[0039] The parts not involved in the utility model are the same as or can be realized by the prior art, and will not be described in detail here.
[0040] Although the embodiments of the utility model have been shown and described, the specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and those skilled in the art can make modifications, replacements and variations of the embodiments without creative contribution after reading the specification without departing from the principles and purposes of the utility model, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
