Description

Technical Field

[0001] This invention relates to the field of network cabinet technology, and in particular to a network cabinet for a computer network monitoring system in a hydropower station. Background Technology

[0002] A network cabinet is a mounting box used to assemble and install panels, plug-ins, boxes, electronic components, devices, and mechanical parts and components into a whole. Among them, the panels and other parts of the network cabinet are mainly used to control the operation of the network system. During the operation of a hydropower station, the control signals and detection signals of the hydropower station units all need to be transmitted by the network. However, hydropower stations are usually built near water bodies with high air humidity. Therefore, in order to avoid the high humidity affecting the working life of electronic components, a network cabinet is needed for the computer network monitoring system of the hydropower station.

[0003] The existing network cabinets have the following main problems during operation:

[0004] First, in order to reduce the humidity inside the network cabinet, desiccants are mostly used for dehumidification. However, after the desiccant absorbs a certain amount of moisture, it needs to be replaced. During the replacement process, the network cabinet needs to be opened, which allows high humidity air from the outside to enter the network cabinet. This not only makes the operation cumbersome, but also reduces the dehumidification effect inside the network cabinet.

[0005] Secondly, the electrical components inside the network cabinet generate a lot of heat, and the high temperature and humidity environment will reduce the lifespan of the electrical components. Summary of the Invention

Multiple triangular pyramids are spaced apart on the bottom side of the heat-conducting plate. The top and bottom of the cabinet are respectively connected to an exhaust pipe and an air supply pipe. The exhaust pipe is connected to an air pump, and the air pump is connected to a connecting pipe. The connecting pipe is connected to the mounting cavity below the thermoelectric cooler, and the air supply pipe is connected to the mounting cavity above the thermoelectric cooler.

[0010] Preferably, ventilation seats are provided at the bottom and top of the cabinet, and the two ventilation seats are respectively connected to the exhaust pipe and the supply pipe.

The connecting seat is drivenly connected to a power component.

[0013] Preferably, the above-mentioned power component includes:

[0014] The cover is mounted on the outer wall of the base.

[0015] The lead screw is rotatably mounted on the two inner side walls of the cover. The outer side wall of the connecting seat is provided with a threaded hole, through which the lead screw passes. The outer side wall of the base is provided with a through hole for the connecting seat to pass through.

[0016] The motor is mounted on the outer wall of the cover, and the output shaft and lead screw of the motor are fixed.

[0017] Preferably, the base is provided with a water pumping assembly, which includes:

[0018] A sleeve, the aforementioned sleeve being rotatably mounted on the inner side wall of the base;

[0019] Piston rings, the aforementioned piston rings being slidably disposed on the inner side wall of the sleeve;

[0020] Hollow tube, the hollow tube is disposed on the side wall of piston ring, and the hollow tube and the connecting seat are rotatably connected;

[0021] The first check valve is disposed through the outer wall of the sleeve.

[0022] The first hose, one end of which is connected to the first check valve;

[0023] A water suction pipe is provided through the bottom of the outer wall of the base, and the water suction pipe is connected to the first flexible hose.

[0024] The second one-way valve is installed through the outer wall of the hollow tube.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] (1) In this invention, the airflow circulation inside the cabinet is realized by the integrated cooling and dehumidification component. The gas inside the cabinet circulates to the base and is in the space below the heat conduction plate. The high temperature water vapor carried by the gas condenses into water droplets when it encounters the triangular pyramid. Under the action of the water droplets' own gravity, the water droplets fall to the bottom of the base for storage. After the gas passes through this area, it is cooled and dried before entering the cabinet, thus realizing the dehumidification and cooling treatment inside the cabinet.

[0032] (2) The present invention uses a water pumping component and a cleaning component. During the cleaning process of the heat sink fins, the water pumping component is driven to work, which can pump the condensed water in the base to the sponge strip of the cleaning component. While cleaning the heat sink fins, a water film is formed on the surface of the heat sink fins. In combination with the air supply function of the cooling and dehumidifying integrated component, the heat at the heat sink fins is quickly removed, thereby ensuring the normal operation of the semiconductor cooling chip and ensuring the condensation effect at the triangular pyramid.

[0051] The following is combined with Figures 1 to 10 As shown, this embodiment of the invention provides a network cabinet for a hydropower station computer network monitoring system, comprising:

[0052] The main body of the network cabinet includes a base 5 and a cabinet 1 connected to each other. The cabinet 1 is located on top of the base 5. The base 5 has an installation cavity. The cabinet 1 is provided with a mounting bracket 3 for fixing network control equipment. The mounting bracket 3 is detachably installed inside the cabinet 1. The mounting bracket 3 and the cabinet 1 can be detachably connected by a bolt group. The bolt group connection method can realize the quick connection or disassembly of the mounting bracket 3 and the cabinet 1. The cabinet 1 is provided with a cabinet door on the side. The cabinet door can not only install or disassemble the mounting bracket 3, but also improve the security of the network control equipment inside the cabinet 1.

[0053] The integrated cooling and dehumidification component includes a semiconductor cooling chip 23 disposed in the mounting cavity, with the cold end of the semiconductor cooling chip 23 facing the bottom of the base 5. The hot end of the semiconductor cooling chip 23 is provided with heat dissipation fins 26, and the cold end of the semiconductor cooling chip 23 is provided with a heat-conducting plate 24. Multiple triangular pyramids 25 are spaced apart on the bottom side of the heat-conducting plate 24, with the apexes of the triangular pyramids 25 facing the bottom side of the base 5, allowing water droplets to easily slide off the triangular pyramids 25. The top and bottom of the cabinet 1 are respectively connected to exhaust pipes. The exhaust pipe 7 and the air supply pipe 6 are connected to an air pump. The inlet of the air pump is connected to the exhaust pipe 7, and the outlet of the air pump is connected to a connecting pipe 27. The connecting pipe 27 is connected to the mounting cavity below the semiconductor cooling chip 23, and the air supply pipe 6 is connected to the mounting cavity above the semiconductor cooling chip 23. Both the exhaust pipe 7 and the connecting pipe 27 are connected to the air pump through flanges, which allows the exhaust pipe 7 and the connecting pipe 27 to be disassembled. A gasket is placed at the connection between the two to enhance the sealing of the connection, prevent gas leakage, and improve the gas circulation effect.

[0054] In this invention, the airflow circulation inside the cabinet 1 is achieved through the integrated cooling and dehumidification component. The gas inside the cabinet 1 circulates to the base 5. After being in the space below the heat-conducting plate 24, the high-temperature water vapor carried by the gas condenses into water droplets when it encounters the triangular pyramid 25. Under the action of the water droplets' own gravity, the water droplets fall to the bottom of the base 5 for storage. After passing through this area, the gas is cooled and dried before entering the cabinet 1, thus achieving dehumidification and cooling treatment inside the cabinet 1.

[0055] Preferably, ventilation seats 4 are provided at the bottom and top of the cabinet 1. The ventilation seats 4 are used to guide airflow and have air channels. The two ventilation seats 4 are respectively connected to the exhaust pipe 7 and the supply pipe 6.

[0056] In this embodiment, the design of the ventilation seat 4 enables the airflow inside the cabinet 1 to be guided. The ventilation seat 4 and the cabinet 1 are detachably connected and can be connected by bolts to achieve quick connection or disassembly.

[0057] Preferably, the heat dissipation fins 26 are provided with a cleaning component; the cleaning component includes a connecting seat 17 slidably disposed on the side wall of the mounting cavity of the base 5, and also includes a plurality of sponge strips 19 equidistantly disposed at the bottom of the connecting seat 17, wherein the plurality of sponge strips 19 abut against the heat dissipation fins 26, and the connecting seat 17 is connected to a power component.

[0058] In this embodiment, during the operation of the power component, the connecting seat 17 is driven to reciprocate within the base 5. During the movement of the connecting seat 17, the sponge strip 19 is driven to move along the surface of the heat dissipation fin 26. The sponge strip 19 cleans the heat dissipation fin 26, ensuring the heat dissipation efficiency of the heat dissipation fin 26.

[0059] Preferably, the power assembly includes: a cover 12, which is disposed on the outer side wall of the base 5; a lead screw 16, which is rotatably disposed on two inner side walls of the cover 12; a threaded hole is provided on the outer side wall of the connecting seat 17, through which the lead screw 16 passes; a through hole is provided on the outer side wall of the base 5 for the connecting seat 17 to pass through; and a motor 18, which is disposed on the outer side wall of the cover 12, and the output shaft of the motor 18 is fixed to the lead screw 16.

[0060] In this embodiment, during the operation of the motor 18, the lead screw 16 is driven to rotate. When the lead screw 16 rotates, it engages with the threaded hole on the connecting seat 17, causing the connecting seat 17 to move within the base 5. The reverse rotation of the motor 18 causes the connecting seat 17 to reset, thereby realizing the reciprocating movement of the connecting seat 17 within the base 5. During the movement of the connecting seat 17, the sponge strip 19 moves along the surface of the heat dissipation fin 26, cleaning the heat dissipation fin 26 through the sponge strip 19, thus ensuring the heat dissipation efficiency of the heat dissipation fin 26.

[0061] Preferably, the base 5 is provided with a water pumping assembly, which includes: a sleeve 13 rotatably mounted on the inner wall of the base 5; a piston ring 28 slidably mounted on the inner wall of the sleeve 13; a hollow tube 14 mounted on the side wall of the piston ring 28 and rotatably connected to a connecting seat 17; a first one-way valve 20 penetrating the outer wall of the sleeve 13; a first flexible hose 15, one end of which is connected to the first one-way valve 20; a water pumping pipe 11 penetrating the bottom of the outer wall of the base 5 and connected to the first flexible hose 15; a second one-way valve 21 penetrating the outer wall of the hollow tube 14; and a second flexible hose 22, one end of which is connected to the second one-way valve 21 and the other end of which is connected to the sponge strip 19.

[0062] In this embodiment, during the movement of the connecting seat 17, the hollow tube 14 is compressed into the sleeve 13. During the resetting process of the connecting seat 17, the hollow tube 14 extends out of the sleeve 13, realizing the reciprocating movement of the piston ring 28 within the sleeve 13. During this process, the condensate at the bottom of the base 5 is drawn into the sleeve 13 through the water suction pipe 11, the first hose 15, and the first one-way valve 20. Then, the condensate is transported to the sponge strip 19 through the second one-way valve 21 and the second hose 22, making the sponge strip 19 wet. As the sponge strip 19 moves along the surface of the heat dissipation fins 26, the surface of the heat dissipation fins 26 becomes wet, which also improves the cleaning effect.

[0063] This invention utilizes a water pumping component and a cleaning component. During the cleaning process of the heat sink fins 26, the water pumping component is activated, drawing condensate from the base 5 to the sponge strip 19 of the cleaning component. While cleaning the heat sink fins 26, a water film is created on the surface of the heat sink fins 26. This, combined with the air supply function of the integrated cooling and dehumidification component, allows the heat at the heat sink fins 26 to be quickly removed, thus ensuring the normal operation of the semiconductor cooling chip 23 and guaranteeing the condensation effect at the triangular pyramid 25.

[0064] Preferably, the base 5 is provided with a drying assembly, which includes: a drying box 8, which is disposed on the top of the outer wall of the base 5 and whose inlet is connected to the mounting cavity of the base 5, and is positioned above the heat dissipation fins 26; a box body 10, which is slidably inserted into the top of the drying box 8, and has a porous structure, and is filled with desiccant; and a housing 2, which is disposed on the top of the outer wall of the base 5 and is connected to the base 5, and has a blower disposed inside the housing 2; the drying box 8 and the housing 2 are symmetrically arranged about the middle of the base 5.

[0065] In this embodiment, during the operation of the blower, gas is blown into the space above the heat dissipation fins 26 in the base 5, and then output after passing through the box 10 of the drying box 8. When the airflow passes through the heat dissipation fins 26, it carries away the heat of the heat dissipation fins 26. Combined with the evaporation of water, the heat dissipation effect of the heat dissipation fins 26 is ensured, thereby ensuring the normal operation of the semiconductor cooling chip 23 and ensuring the condensation effect at the triangular pyramid 25. Finally, the airflow is adsorbed by the desiccant in the box 10, which reduces the overall humidity of the environment in which the cabinet 1 is located.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
