DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] like Figures 1 to 3As shown, the utility model provides a prefabricated cabin high-pressure side environmental protection cabinet for new energy, which is an incoming line cabinet and two outgoing line cabinets, including a switch room 1, a cable room 2 and a pressure relief chamber 3. The switch room 1 is located at the top of the pressure relief chamber 3, and the cable room 2 is located at the side of the pressure relief chamber 3. The switch room 1 and the pressure relief chamber 3 are connected through a pressure relief valve. The pressure relief valve controls the unidirectional flow of gas from the switch room 1 to the pressure relief chamber 3. Specifically, openings 4 for installing the pressure relief valve are respectively provided on the bottom surface of the switch room 1 and the top surface of the pressure relief chamber 3. The pressure relief valve adopts the reverse arch crocodile tooth type bursting disc in the prior art, and its model is QTYEH75. The structure of the pressure relief valve is not shown in the figure. It is shown that the cable chamber 2 and the pressure relief chamber 3 are connected through a pressure relief plate 5 that can only be opened from the cable chamber 2 to the pressure relief chamber 3. The bottom of the pressure relief chamber 3 is provided with a pressure relief port 6, which is connected to the cable trench at the bottom of the environmental protection cabinet on the high-pressure side of the new energy prefabricated cabin, wherein the pressure relief port 6 can be a through hole opened on the bottom surface of the pressure relief chamber 3, or the bottom surface of the pressure relief chamber 3 can be omitted, and the entire bottom opening of the pressure relief chamber 3 is used as the pressure relief port 6. The cable trench is a space for storing cables entering the cable chamber. The structure of the cable trench can be made of the existing technology. The utility model does not improve its structure, and its specific structure is not shown in the figure. When in use, the environmental protection cabinet on the high-pressure side of the prefabricated cabin for new energy is placed on the cable trench, and the end cover at the cable trench opposite to the pressure relief port 6 is removed, so that the pressure relief port 6 is connected to the cable trench. Because the inner wall of the cable trench is a reinforced concrete structure with a strong pressure bearing capacity, the structure of the cable trench will not be damaged after the pressure in the pressure relief chamber 3 is released into the cable trench.

[0036] When a fault occurs in the switch room 1 and pressure relief is required, the air pressure in the switch room 1 increases, and the pressure relief valve connects the switch room 1 and the pressure relief chamber 3, guides the high-pressure gas in the switch room 1 to the pressure relief chamber 3, and then guides it to the cable trench through the pressure relief port 6. At this time, the pressure relief plate 5 is in a closed state, and the cable room 2 and the pressure relief chamber 3 are not connected, which can effectively prevent the high-pressure gas in the pressure relief chamber 3 from entering the cable room 2 and causing damage to the electrical components in the cable room 2; when a fault occurs in the cable room 2 and pressure relief is required, the air pressure in the cable room 2 increases, pushing the pressure relief plate 5 to open in the direction of the pressure relief chamber 3 to connect the cable room 2 and the pressure relief chamber 3, guide the high-pressure gas in the cable room 2 to the pressure relief chamber 3, and then guide it to the cable trench through the pressure relief port 6. At this time, since the air pressure in the pressure relief chamber 3 is higher than the air pressure in the switch room 1, the one-way valve is in a closed state, so the high-pressure gas will not enter the switch room 1. By connecting the switch room 1 and the cable room 2 to the pressure relief chamber 3 respectively, and setting a pressure relief port 6 connected to the cable trench at the bottom of the pressure relief chamber 3, not only can the high-pressure gas be discharged downward to the cable trench to avoid personal injury, but also the rationality of the structural layout of the environmental protection cabinet is improved compared with the method of setting two separate pressure relief channels. Furthermore, in order to allow all high-pressure gas to be guided to the cable trench, the width of the pressure relief port 6 is set to be no greater than the width of the cable trench, and the length of the pressure relief port 6 is set to be no greater than the length of the cable trench.

[0037] like Figures 4 to 6 As shown, a through hole 7 is opened on the cable chamber 2, and the pressure relief plate 5 covers the through hole 7, and the edge of the pressure relief plate 5 exceeds the edge of the through hole 7, and the pressure relief plate 5 is fixed on the side wall of the cable chamber 2 close to the pressure relief chamber 3, so that when the air pressure in the pressure relief chamber 3 is higher than the air pressure in the cable chamber 2, the pressure relief plate 5 is firmly attached to the through hole 7 to avoid connecting the cable chamber 2 and the pressure relief chamber 3; when the air pressure in the cable chamber 2 is higher than the air pressure in the pressure relief chamber 3, the pressure relief plate 5 is broken or flipped to open the through hole 7 to connect the cable chamber 2 and the pressure relief chamber 3.

[0038] like Figure 6 As shown, further, the upper end of the pressure relief plate 5 is fixedly connected to the side wall of the cable chamber 2, the lower end of the pressure relief plate 5 is snap-fitted to the side wall of the cable chamber 2, and a plurality of strength weakening holes 8 are arranged on the pressure relief plate 5, the strength weakening holes 8 are arranged in a horizontal line at intervals, and the horizontal line is located between the fixing point of the pressure relief plate 5 and the upper edge of the through hole 7, so as to reduce the gas pressure in the cable chamber 2 when it breaks through the pressure relief plate 5, and avoid the situation that the cable trench and / or the items in the cable trench are seriously damaged due to the instantaneous high gas pressure of the released gas. Specifically, the upper end of the pressure relief plate 5 is fixedly connected to the side wall of the cable chamber 2 through a threaded connector.

[0039] like Figure 5 As shown, in order to facilitate the assembly of the pressure relief plate 5, a clamping plate 9 is arranged at the lower end of the pressure relief plate 5, and the clamping plate 9 intersects with the pressure relief plate 5 to form an open structure with a small upper part and a large lower part, and the open structure passes through the through hole 7 and is clamped on the side wall of the cable chamber 2 away from the pressure relief chamber 3, and the size of the part where the open structure contacts the side wall of the cable chamber 2 is not less than the wall thickness of the cable chamber 2; during installation, the open structure is first clamped on the side wall of the cable chamber 2 away from the pressure relief chamber 3 to position the pressure relief plate 5, and then the upper end of the pressure relief plate 5 is fixedly connected to the side wall of the cable chamber 2 close to the pressure relief chamber 3.

[0040] like Figures 1 to 2 As shown, the outer shell of the switch chamber 1 is made of stainless steel. As a preferred embodiment of the utility model, the switch chamber 1 is made of 304 stainless steel, and its interior is filled with dry gas, such as N2, to enhance the insulation strength and improve the safety performance during use. In order to avoid deformation of the switch chamber 1 during inflation, a number of spaced reinforcing ribs 10 are respectively arranged on the top, left and right sides of the switch chamber 1, and the spacing between the reinforcing ribs 10 on the same surface is consistent; further, the spacing between the reinforcing ribs 10 on different surfaces is also consistent. Through mechanical analysis and physical verification, the reinforcing ribs 10 are arranged in the manner described in this application, and the switch chamber 1 is not easily deformed after inflation.

[0041] Continue to refer Figures 1 to 2A metal lifting frame 11 is provided on the left and right sides of the top surface of the switch room 1, and the lifting frame 11 is welded to the top surface of the switch room 1. Since the entire bottom surface of the lifting frame 11 is welded to the top surface of the switch room 1, compared with the prior art method of connecting the lifting frame 11 and the switch room 1 together only through a few spaced connection points, when the present application is lifting, the part where the lifting frame 11 is connected to the switch room 1 is subjected to uniform force, and the top surface of the switch room 1 will not be subjected to force at intervals, so that the top surface of the switch room 1 will not bend or deform; further, the length of the lifting frame 11 is set to be equal to the width of the top surface of the switch room 1.

[0042] like Figures 1 to 2 , Figure 7 As shown, the environmental protection cabinet on the high-pressure side of the prefabricated cabin for new energy also includes an instrument room 12 and a mechanism room 13. The mechanism room 13 is placed on the top surface of the cable room 2, and the pressure relief chamber 3 is arranged next to the back of the cable room 2. The left and right sides of the mechanism room 13, the left and right sides of the cable room 2, and the left, right and back sides of the pressure relief chamber 3 are surrounded by an integrated frame 14. Preferably, the left side of the cable room 2 and the left side of the pressure relief chamber 3 are the same plate, and the right side of the cable room 2 and the right side of the pressure relief chamber 3 are the same plate. The frame 14 is made of 2mm thick fluorine aluminum zinc plate, and the plates constituting the frame are fastened and connected by screws. Through such an arrangement, the frame 14 and the switch room 1 can be processed in parallel without affecting each other, thereby improving the processing efficiency.

[0043] like Figure 7 As shown, the switch chamber 1 is located in the area enclosed by the back of the mechanism chamber 13 and the top surface of the pressure relief chamber 3, and the left side, right side and back side of the frame 14 are higher than the top surface of the pressure relief chamber 3 to form a groove 15 that is adapted to the size of the switch chamber 1. The switch chamber 1 is placed in the groove 15 to limit the placement position of the switch chamber 1.

[0044] like Figure 8 As shown, the instrument room 12 is placed on the top surface of the mechanism room 13. The switch room 1 is provided with a pressure relief valve at the part connected to the pressure relief chamber 3, and the rest of the parts are sealed structures. The pressure relief chamber 3 is provided with a pressure relief valve at the part connected to the switch room 1, a pressure relief plate 5 at the part connected to the cable room 2, and a pressure relief port 6 at the bottom, and the rest of the parts are also sealed structures. The top surface of the instrument room 12 is a downward inclined surface, and the lowest end of the inclined surface faces the switch room 1. When the temperature is low, the water condensed on the top of the instrument room 12 can flow out of the box under the guidance of the inclined surface to prevent the secondary components from getting wet.

[0045] like Fig. 9As shown, the internal space of the instrument room 12 is divided into several independent compartments by partitions 16, and each compartment is equipped with a heating and dehumidification module so that the compartments do not affect each other. The instrument room 12 is made of 2mm thick Q235 cold-rolled plate, the surface of which is sprayed with anti-corrosion paint, and the various plates are fastened and connected by screws.

[0046] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
