Detailed implementation manners

[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the drawings and embodiments.

[0019] Embodiment 1:

[0020] As Figure 1 and Figure 2 shown, where Figure 1 is the schematic diagram of the overall structure of a power supply with a waterproof structure, Figure 2 is the schematic diagram of the structure of the serpentine tube 105. The present invention provides a power supply with a waterproof structure: including a housing 101 and an auxiliary device. The housing 101 has a support part 102, and the support part 102 is lower than the top opening of the housing 101. The auxiliary device includes a top cover 103, a sealing plate 104, a serpentine tube 105, a wire tube 106, a power supply assembly and a detection assembly. The power supply assembly includes a mounting plate 107 and a power supply body 108. The detection assembly includes a temperature sensor 109 and a water level sensor 110. Through the foregoing solution, it is possible to improve the waterproof effect when performing waterproof treatment on the power supply. It can be understood that the foregoing solution can improve the waterproof effect of the power supply.

[0021] In this embodiment, the housing 101 has a support part 102, and the support part 102 is lower than the top opening of the housing 101. The function of the support part 102 is to facilitate the fixed installation of the top cover 103 and to facilitate the formation of a water blocking part.

[0022] Among them, the top cover 103 is detachably connected to the shell 101 and is located at the top of the shell 101, the sealing plate 104 is fixedly connected to the shell 101 and is located at the bottom left side of the shell 101, the serpentine tube 105 is fixedly connected to the sealing plate 104 and is located on the sealing plate 104, the wire tube 106 is fixedly connected to the shell 101 and is located on the side of the shell 101 close to the support part 102, the power supply assembly is arranged in the shell 101, and the detection assembly is installed on the outer wall of the shell 101. Threaded through holes are arranged on the four corners of the support portion 102, so that the top cover 103 can be installed by bolts. The upper side of the top cover 103 can be slidably matched with the shell 101 at the upper side of the support portion 102. The bottom surface of the mounting portion is matched with the top surface of the support portion 102 to set a sealing gasket for sealing. The sealing plate 104 is installed on the outer side of the rectangular opening on the lower left side of the shell 101 by bolts. The rectangular opening is convenient for the installation of the serpentine tube 105. The serpentine tube 105 adopts a seamless steel pipe. The straight pipes on the input and output sides are respectively welded to the sealing plate 104, and connecting flanges are respectively arranged on the inlet and outlet, which are respectively connected with the external coolant delivery pipeline and the return pipeline. The sealing plate 104 and the mounting contact surface of the shell 101 are provided with a sealing gasket for sealing to improve the waterproof performance. The mounting plate of the wire tube 106 is installed on the shell 101 by bolts. The power supply component is arranged in the shell 101 for providing electric energy. The detection component is installed on the outer wall of the shell 101 for realizing internal temperature detection and water level detection.

[0023] Secondly, the wire tube 106 is L-shaped, connected to the inside of the housing 101, and opened downward. The wire tube 106 has an L-shaped cross section, and the inside is a cable channel, which is connected to the inside of the housing 101 to facilitate the cable installation and connection. After the wire tube 106 is installed, the opening is downward to prevent water from flowing from the cable surface into the housing 101.

[0024] Then, the mounting plate 107 is welded to both sides of the inner wall of the housing 101; the power source body 108 is detachably connected to the mounting plate 107 and is located on the mounting plate 107. The mounting plate 107 is symmetrically welded to the inner wall of the housing 101, and the protective shell of the power source body 108 is fixed to the mounting plate 107 by bolts to achieve hoisting. After the power source body 108 is installed, the bottom does not abut and interfere with the serpentine tube 105.

[0025] Finally, the temperature sensor 109 is fixedly connected to the housing 101 and is located on the left side wall of the housing 101; the water level sensor 110 is fixedly connected to the housing 101 and is located on the front side wall of the housing 101. The temperature sensor 109 is fixed to the housing 101 by bolts, and its probe part extends into the housing 101 for internal temperature detection and feedback to the control system. The water level sensor 110 is installed on the housing 101 by bolts for detecting the water level inside the housing 101. When the inside of the housing 101 is invaded by water flow, at this time, the internal water level can be detected through the water level sensor 110. When the water level signal is detected, the water level will be at the limit position where it is about to submerge the bottom of the power supply main body 108. At this time, the control system receives the feedback signal and can control the alarm device to give an alarm prompt for timely handling.

[0026] When using the present utility model to improve the waterproof effect of the power supply, first, when installing the top cover 103, a sealing gasket is arranged in a matching manner between the bottom surface of its installation part and the top surface of the supporting part 102 for sealing, or direct end-face contact sealing can also be adopted. Then, after the top cover 103 is installed by bolts, since the supporting part 102 is lower than the top opening of the housing 101, at this time, the sealing gasket will also be lower than the top opening of the housing 101. When the sealing gasket is deformed and fails or the connecting bolts of the top cover 103 are loose, due to the height difference distance between the supporting part 102 and the top opening of the housing 101, a water-blocking part is formed, and good water-blocking and waterproofing can also be achieved to prevent water flow from entering the inside of the housing 101. Further, circulating coolant can be introduced into the inside through the serpentine tube 105. When the coolant circulates, it exchanges heat with the internal hot air, takes away heat and reduces the internal temperature, so as to cool down and dissipate heat during the operation of the power supply assembly. Furthermore, when performing the waterproof treatment of the power supply, the waterproof effect can be improved.

On the basis of the first embodiment, the present utility model provides a power supply with a waterproof structure, and the auxiliary device further includes a waterproof breathable membrane 201 and a pressing plate 202.

[0029] Among them, the waterproof and breathable film 201 is pasted on the outer side of the ventilation opening of the housing 101; the pressing plate 202 is fixedly connected to the housing 101 and is located on the outer side of the waterproof and breathable film 201. A plurality of rectangular ventilation openings arranged in a line are formed on the front side wall and the rear side wall of the housing 101. The waterproof and breathable film 201 is pasted on the outer side of the rectangular ventilation openings to cover the rectangular ventilation openings. When ensuring the normal flow of air, water can be prevented from entering the interior. The pressing plate 202 is installed on the housing 101 through bolts. When the pressing plate 202 is installed, the four edge edges of the waterproof and breathable film 201 are pressed to further improve its stability.

[0030] In this embodiment, further, a plurality of rectangular ventilation openings arranged in a line are formed on the housing 101, the waterproof and breathable film 201 is fixedly pasted on the outer side of the rectangular ventilation openings, and finally fixed by the pressing plate 202. When the power supply assembly works, the heat dissipation channels can be increased, which is beneficial to heat dissipation during work.
