[0028] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] Embodiment 1: As shown in the attached Figure 1 As shown: The present invention provides a prefabricated cabin device for electrical equipment of a new energy booster station, comprising a container-type frame 1, an industrial air conditioner 5 and a heat dissipation component 9;

[0030] A door 10 is installed on the front face of the container-type frame 1, and a ventilation slot 2 is opened on the side wall of the container-type frame 1; a plurality of air intake grilles 3 are arranged in an array on the inner wall of the ventilation slot 2, and a filter screen 4 is installed in the air intake grille 3, and a plurality of switch cabinets 7 are arranged in an array inside the container-type frame 1; the air intake grille 3 can effectively increase the air intake area, so that the external air can smoothly enter the prefabricated cabin, and the filter screen 4 filters dust, impurities and other particulate matter in the air to prevent dust and other pollutants from entering the prefabricated cabin to avoid damage to the electrical equipment; dust accumulation in the switch cabinet 7 may cause insulation performance degradation or short circuit;

[0031] As attached Figure 2 As shown: the industrial air conditioner 5 is installed at the ventilation slot 2; an external machine cover 19 is also fixed to the outer wall of the container-type frame 1. The industrial air conditioner 5 cools the inhaled air through a refrigeration cycle and outputs cold air. The external machine cover 19 is used to protect the air conditioner outdoor unit from external environmental factors such as rain, wind and sand, etc., to ensure its normal operation;

[0032] As attached Figure 3 As shown: the heat dissipation component 9 includes a guide chamber 901, an air ionizer 901b, a shunt pipe 902 and an air outlet 903; the guide chamber 901 is connected between the air outlet end of the industrial air conditioner 5 and the inner top wall of the container-type frame 1, and two groups of shunt pipes 902 are symmetrically fixed to the side walls of the guide chamber 901, the shunt pipe 902 is fixed to the inner top wall of the container-type frame 1, and the shunt pipe 902 is distributed above the switch cabinet 7, and the bottom surface of the shunt pipe 902 is penetrated by the air outlet 903, the inner wall of the guide chamber 901 is fixed with a mounting seat 901a, and the air ionizer 901b is installed in the mounting seat 901a; the guide chamber 901 plays the role of guiding the cold air to flow upward, and the cold air is transferred to the upper side of the guide chamber 901 through the shunt pipe 902. The air outlet 903 allows the cold air to blow vertically downward toward the switch cabinet 7, and the two groups of manifolds 902 cooperate to make the cold air cover all parts of the switch cabinet 7 more evenly, effectively solving the problem of uneven heat dissipation; the cold air flows on the surface of the switch cabinet 7, and takes away the heat generated by the switch cabinet 7 through heat exchange to achieve heat dissipation; the air ion generator 901b generates positive and negative ions by ionizing the air; when an object with static electricity comes into contact with these ions, the ions will neutralize the static electricity charge, thereby eliminating the static electricity; the static electricity around the switch cabinet 7 in the prefabricated cabin may cause equipment failure or damage, and the ions generated by the air ion generator 901b can effectively reduce the harm of static electricity.

[0033] As attached Figure 5As shown: the heat dissipation component 9 also includes a water-absorbing layer 904, which includes a metal mesh 904b and a water-absorbing fiber 904a, and the water-absorbing layer 904 is laid on the inner surface of the shunt pipe 902; the water-absorbing fiber 904a can absorb moisture in the air to prevent moisture from entering the switch cabinet 7; the metal mesh 904b can fix the water-absorbing fiber 904a on the one hand, and on the other hand, it can play a certain conductive role to help release static electricity, and also contribute to the uniform distribution of air.

[0034] As attached Figure 4 As shown: a through slot 17 is passed through the other side wall of the container-type frame 1, and a sealed door 18 is installed at the end of the through slot 17. The prefabricated cabin can be completely opened through the sealed door 18 and the through slot 17, so as to facilitate the arrangement of electrical equipment inside; a plurality of positioning frames 6 are symmetrically installed in the container-type frame 1, and a switch cabinet 7 is installed on the surface of the positioning frame 6. An insulating terminal 11 is installed between the switch cabinet 7 and the container-type frame 1, and a control cabinet 8 is also installed inside the container-type frame 1; the positioning frame 6 is used to fix the switch cabinet 7 to ensure that the position of the switch cabinet 7 in the prefabricated cabin is stable; the insulating terminal 11 can prevent electrical conduction between the switch cabinet 7 and the frame, avoid leakage and short circuit, and ensure the safe operation of the electrical equipment.

[0035] A ceiling 20 is fixedly installed on the top wall of the container-type frame 1, and a plurality of lighting lamps 21 and temperature sensors 22 are installed in an array on the bottom surface of the ceiling 20; the control cabinet 8 is used to centrally control various electrical equipment in the prefabricated cabin, such as the industrial air conditioner 5, the air ionizer 901b, etc. The control cabinet 8 realizes automatic management of the equipment through pre-programmed control logic, for example, the cooling power of the industrial air conditioner 5 is controlled according to the feedback signal of the temperature sensor 22; the lighting lamp 21 is used to provide lighting in the prefabricated cabin, so as to facilitate the staff to operate and maintain in the cabin; the temperature sensor 22 is used to monitor the temperature in the prefabricated cabin in real time, convert the temperature signal into an electrical signal, and transmit it to the control cabinet 8; the control cabinet 8 determines whether it is necessary to adjust the operating status of the industrial air conditioner 5 according to the information fed back by the temperature sensor 22 to keep the temperature in the prefabricated cabin suitable.

[0036] As can be seen from the above, the cold air generated by the industrial air conditioner 5 first enters the guide chamber 901, flows upward under the guidance of the guide chamber and enters the diversion pipe 902, thereby realizing the preliminary distribution and transmission of the cold air.

[0037] The cold air entering the shunt pipe 902 is further evenly distributed to the air outlet 903 above each switch cabinet 7 under the action of the shunt pipe, and then blows vertically downward to the switch cabinet 7, providing a uniform heat dissipation airflow for the switch cabinet 7, effectively solving the problem of uneven heat dissipation of the switch cabinet 7.

[0038] When cold air passes through the shunt pipe 902, the water-absorbing layer 904 absorbs moisture in the air, ensuring that the air entering the switch cabinet is dry, thereby protecting the insulation performance and normal operation of the electrical equipment. At the same time, its metal mesh 904b assists in releasing static electricity, further improving the safety of the equipment.

[0039] The positive and negative ions generated by the air ion generator 901b flow in the guide chamber 901 and the shunt pipe 902 along with the cold air, and finally enter the prefabricated cabin through the air outlet 903; the negative ions combine with dust and other particles in the air to cause them to settle, purifying the air and reducing dust pollution to equipment such as the switch cabinet 7; at the same time, the ions also neutralize the static electricity on the surface of the equipment, preventing the accumulation of static electricity from damaging the equipment, and working together with the water absorption layer 904 to further improve the reliability and stability of the equipment.

[0040] Embodiment 2: As shown in the attached Figure 1 As shown: This embodiment is basically the same as the previous embodiment, except that first connecting seats 15 are fixed to both outer bottom surfaces of the container-type frame 1, and second connecting seats 16 are fixed to both bottom walls of the container-type frame 1;

[0041] As can be seen from the above, the first connecting seat 15 and the second connecting seat 16 are used for the installation of the prefabricated cabin and the connection of other equipment or prefabricated cabins; the connecting seat can be fixed to the basic structure or adjacent prefabricated cabins by bolts and other connecting parts to achieve stable placement and expansion combination of the prefabricated cabin. For example, when the capacity of electrical equipment needs to be increased, a new prefabricated cabin can be conveniently connected.

[0042] Embodiment 3: As shown in the attached Figure 2 As shown: Based on the first embodiment, the bulkhead structure of the container-type frame 1 includes a sealing layer 12, an inner layer 13 and a heat insulating layer 14, and the heat insulating layer 14 is made of polyurethane foam material.

[0043] The sealing layer 12 is mainly used to prevent external air, moisture, etc. from entering the prefabricated cabin, ensuring the sealing of the cabin environment; the inner layer 13 plays a supporting and protective role, and can also provide certain fire prevention, moisture-proof and other functions; the thermal insulation layer 14 is made of polyurethane foam material. The principle is that the closed-cell structure inside the polyurethane foam can effectively prevent heat conduction, reduce heat exchange inside and outside the prefabricated cabin, make the temperature inside the prefabricated cabin more stable, and avoid the influence of the external environment temperature on electrical equipment such as the switch cabinet 7.

[0044] As can be seen from the above, at the construction site of the new energy booster station, the prefabricated cabin is installed on the pre-prepared basic platform through the first connecting seat 15 at the bottom and the second connecting seats 16 on the bottom walls on both sides to ensure its stable placement. The switch cabinet 7 is installed on the symmetrically arranged positioning frame 6 in the container-type frame 1 through the sealing door 18 and the through groove 17, and the insulating terminal 11 is connected, and the control cabinet 8 is installed in the frame.

[0045] External air enters the prefabricated cabin through the air intake grille 3 of the inner wall array of the ventilation slot 2, and the filter plate 4 filters out dust and impurities in the air. The industrial air conditioner 5 installed at the ventilation slot 2 starts the refrigeration cycle, cools the inhaled air and outputs cold air. The cold air first enters the guide chamber 901, which guides the cold air to flow upward into the diverter pipe 902. The air outlet 903 on the bottom of the diverter pipe 902 blows the cold air evenly and vertically downward toward the switch cabinet 7, taking away the heat generated by the operation of the switch cabinet 7, achieving heat dissipation, and effectively solving the problem of uneven heat dissipation of the switch cabinet.

[0046] The air ionizer 901b in the diversion chamber 901 continuously ionizes the air to produce positive and negative ions. These ions flow with the cold air in the diversion chamber 901 and the shunt pipe 902 and enter the prefabricated cabin through the air outlet 903. The negative ions combine with the dust in the air to make it settle, purify the air, and reduce the dust pollution to the switch cabinet and other equipment; at the same time, the ions neutralize the static electricity on the surface of the equipment to prevent the accumulation of static electricity from damaging the equipment. The water absorption layer 904 on the inner surface of the shunt pipe 902 absorbs moisture in the air to prevent moisture from entering the switch cabinet and protect the insulation performance of the electrical equipment. The metal wire mesh 904b assists in releasing static electricity, further improving the safety of the equipment.

[0047] The lighting lamps 21 installed in an array on the bottom of the ceiling 20 provide lighting inside the cabin, which is convenient for the staff to operate and maintain. The temperature sensor 22 monitors the temperature inside the prefabricated cabin in real time and converts the signal into an electrical signal and transmits it to the control cabinet 8. The control cabinet 8 automatically controls the cooling power of the industrial air conditioner 5 according to the preset temperature range and the feedback information of the temperature sensor 22 to maintain the appropriate temperature inside the cabin. For example, when the temperature rises above the set upper limit, the control cabinet 8 increases the cooling capacity of the industrial air conditioner 5; when the temperature drops to the set lower limit, the control cabinet 8 reduces the cooling capacity of the industrial air conditioner 5 or suspends cooling.

[0048] The staff regularly enters the prefabricated cabin through the hatch 10 to check the operating conditions of various electrical equipment, including the switch cabinet 7, industrial air conditioner 5, air ionizer 901b, etc. Clean the dust and debris that may be blocked on the air intake grille 3 to ensure smooth ventilation; check the water absorption of the water absorption layer 904, and replace the water absorption fiber 904a if necessary; check whether the temperature sensor 22 is working properly to ensure accurate temperature monitoring and ensure long-term stable and efficient operation of the prefabricated cabin.
