Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and cannot be understood as a limitation to the present invention.

[0023] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0024] An outdoor integrated electrical and instrument control cabinet for medium and small-sized cryogenic nitrogen production equipment, as Figure 1 - Figure 5 shown, the cabinet body 1 includes an electric control cabinet 2, a first instrument control cabinet 3 and a second instrument control cabinet 4. A rainproof mechanism is installed on the top of the cabinet body 1, and a support mechanism is installed at the bottom.

[0025] In this embodiment, the electric control cabinet 2 adopts double-layer stainless steel doors. Instrument meters, signal lights and operation buttons are installed on the inner door, and a viewing window is installed on the outer door.

[0026] In actual operation, when it is necessary to view the internal situation, it can be observed through the viewing window of the outer door, so that it can be viewed without opening the door. If it is necessary to operate the internal equipment, open the outer door and operate on the inner door, which can ensure safety.

[0027] In this embodiment, the front panel of the first instrument control cabinet 3 adopts a transparent explosion-proof glass framed door, and a control host unit, an analytical instrument unit and a UPS uninterruptible power supply unit are arranged in the cabinet.

[0028] This design not only facilitates observing the operation of internal equipment, but also ensures the safety and stability of the equipment.

[0029] In this embodiment, the second instrument control cabinet 4 is used to install PLC or DCS control cards and various communication components.

[0030] Through reasonable layout, the various communication components and control cards can work efficiently in cooperation.

[0031] In some examples, the rainproof mechanism is a rain cap 5 detachably installed on the top of the cabinet body 1, and it adopts a double-layer structure design. This design can effectively prevent rain. At the same time, the double-layer rain cap 5, in addition to the rainproof function, also has a sun protection and heat insulation function, meeting the waterproof and dustproof requirements for outdoor installation. At the same time, the three different cabinets have independent rain caps and are detachable, and can also meet the needs of the cabinet body 1 to be sent to their respective integrators for integration.

[0032] Of course, in some other examples, the rain shelter mechanism can also be a double-layer rain shelter plate detachably installed on the top of the cabinet body 1. In this embodiment, the specific structure of the rain shelter mechanism is not completely limited.

[0033] In some examples, the rain caps 5 are interconnected and installed on the top of the cabinet body 1 through a snap structure.

[0034] Of course, in some other examples, the rain caps 5 can also be interconnected and installed on the top of the cabinet body 1 through bolts. In this embodiment, the interconnection of the rain caps 5 and the connection with the cabinet body 1 are not specifically limited.

[0035] In this embodiment, the base 6 of the support mechanism is used to meet the requirements of cable entry and exit from the bottom and floor mounting. Moreover, a forklift notch 61 is provided on the outer wall of the base 6, which is convenient for handling and installation. At the same time, the length and width of the base 6 are 5 cm smaller than the length and width of the cabinet body 1, making the overall structure more beautiful.

[0036] In this embodiment, a ventilation opening 7 is provided on the support mechanism. At the same time, an air-conditioning refrigeration unit 8 is installed on the outer wall of the second instrument control cabinet 4, and a strong exhaust system 9 is installed inside the cabinet body 1. During the operation of the equipment, the ventilation opening 7 ensures air circulation. The air-conditioning refrigeration unit 8 is automatically turned on or off according to the temperature set by the temperature and humidity controller inside the cabinet. The generated cold air is evenly distributed in the integrated cabinet space through the air flow channel. The strong exhaust system 9 is automatically started when the air-conditioning refrigeration unit 8 fails, jointly ensuring that the electrical and electronic components dissipate heat in time during operation and avoiding high-temperature damage accidents.

[0037] The working principle of the present utility model is as follows: When the temperature inside the cabinet body 1 rises, the temperature and humidity controller (in the relevant control module inside the second instrument control cabinet 4) detects the temperature change; if the temperature exceeds the set value, the air-conditioning refrigeration unit 8 is started; the cold air generated by the air-conditioning refrigeration unit 8 is evenly distributed in the integrated cabinet space through the air flow channel, reducing the temperature inside the cabinet body 1; at the same time, the strong exhaust system 9 also assists in air circulation and discharges the hot air out of the cabinet body 1; if the air-conditioning refrigeration unit 8 fails, the strong exhaust system 9 will increase the exhaust intensity to try to maintain the temperature inside the cabinet body 1 within a reasonable range and prevent the electrical and electronic components from being damaged due to high temperature;

[0038] The temperature and humidity controller also monitors the humidity inside the cabinet body 1; if the humidity exceeds the set value, on the one hand, the air circulation is strengthened through the ventilation opening 7 to exchange the air inside the cabinet body 1 with the outside air and reduce the humidity; on the other hand, during the refrigeration process, the air-conditioning refrigeration unit 8 also dehumidifies the air to further control the humidity inside the cabinet body 1 and ensure that the electrical and electronic components are in a suitable humidity environment;

[0039] The operator observes the internal situation through the visual window of the outer door of the electrical control cabinet 2. When operation is required, the outer door is opened. The instruments and signal lights on the inner door can obtain the equipment operation status information, and the operation buttons can control the relevant equipment; for example, controlling the start and stop of the cryogenic nitrogen production equipment, adjusting the operation parameters, etc.; the instruments on the inner door are connected to the electrical system in the cabinet 1 to transmit the equipment operation data to the operator. At the same time, the operator's operation instructions are transmitted to the corresponding equipment actuator through the buttons and the internal electrical circuit;

[0040] The control host unit in the first instrument control cabinet 3 receives signals from various sensors (such as pressure transmitters, temperature sensors, etc., which may be located at relevant parts of the cryogenic nitrogen production equipment). These signals are transmitted to the control host unit through communication lines; the analysis instrument unit analyzes and processes these signals, for example, analyzing parameters such as the purity and flow rate of nitrogen; the UPS uninterruptible power supply unit provides uninterruptible power for the entire first instrument control cabinet 3 to ensure that the control host unit and the analysis instrument unit can continue to work normally in case of external power failure, ensuring that data is not lost and the equipment operation is not affected;

[0041] The PLC or DCS control card installed in the second instrument control cabinet 4 receives the analysis and processing results from the first instrument control cabinet 3 and the signals from other relevant equipment, and issues control instructions to each actuator (such as compressors, valves, etc.) of the cryogenic nitrogen production equipment through internal logic operations and control algorithms; each communication component ensures the accuracy and timeliness of signal transmission between the first instrument control cabinet 3 and the second instrument control cabinet 4 and with other relevant equipment, ensuring the coordinated operation of the entire control system;

[0042] The rain shelter mechanism on the top of the cabinet 1, its rain cap 5 is designed with a double-layer structure, which can effectively prevent rainwater from entering the cabinet 1; the detachable installation method is convenient for disassembly and installation during the transportation or maintenance of the cabinet 1, ensuring that the cabinet 1 can be well protected from rain at different stages;

[0043] The support mechanism at the bottom of the cabinet 1, its base 6 not only meets the requirements of cable entry and exit from the bottom and floor installation, but also the forklift slots 61 opened on it facilitate the handling and installation of the cabinet 1; the length and width of the base 6 are smaller than those of the cabinet 1, improving the overall aesthetics; through the coordinated action of the rain shelter mechanism and the support mechanism, the overall protection performance of the cabinet 1 is improved, protecting the electrical and electronic components in the cabinet 1 from the influence of external environmental factors.

[0044] Although embodiments of the present utility model have been shown and described, the specific embodiments are only interpretations of the present utility model and do not limit the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
