It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0064] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0065] The water tank in the existing wastewater treatment device on the railcar is mainly made of multiple welded stainless steel sheets. In order to ensure the strength of the tank body 100, a reinforcing component 300 consisting of multiple reinforcing ribs is also required on the outer surface of the tank body 100. The reinforcing component 300 is generally also made of stainless steel.

[0066] The box 100 with this structure has two main drawbacks. First, its heavy weight increases production costs and energy consumption during railcar operation. Second, the box 100 requires multiple welding processes to form, resulting in significant deformation after welding and a high risk of liquid leakage at the weld seams. This necessitates repeated reshaping and inspection, impacting the testing efficiency of the box 100. Furthermore, after welding, the weld seams require acid pickling, followed by rinsing of the entire box 100. However, residual chemicals within the box 100 can enter the environment with the water flow, potentially causing pollution.

[0067] Based on the above description, one or more embodiments of this application provide a housing 100, which will be described below with reference to the accompanying drawings.

[0068] like Figures 1 to 4 As shown in the illustration, the box 100 in this embodiment includes a box body 101 and a cover 102. The box body 101 is a basalt fiber composite material, and has a receiving cavity inside. The top of the box body 101 has an opening communicating with the receiving cavity. The cover 102 is connected to the top of the box body 101 and is used to seal the opening. At least one of the box body 101 and the cover 102 has a mounting member 200 on its surface. The mounting member 200 is used to connect a reinforcing assembly 300 that reinforces the box body 101 or the cover 102.

[0069] The box 100 provided in this embodiment consists of a box body 101 with an open top and a cover 102 for sealing the open top of the box body 101. The box body 101 and the cover 102 are two separate components connected together. Compared with the traditional method of welding multiple stainless steel sheets to form the box 100, this reduces welding and shaping operations, thereby improving processing efficiency. The box body 101 is made of basalt fiber composite, which has a lower density than stainless steel, thus reducing the weight of the box 100. Furthermore, by providing mounting parts 200, the reinforcing components 300 are connected to the box body 101 or the cover 102, which also helps to reduce welding deformation, thereby further improving the processing efficiency of the box 100.

[0070] In this application embodiment, the railcar refers to a vehicle that runs on tracks such as high-speed rail or bullet train tracks. It is understood that the housing 100 can be configured not only on railcars but also on other products with sewage discharge requirements.

[0071] In some embodiments, both the box body 101 and the lid 102 in this application are basalt fiber composites, which helps to further reduce the weight of the box 100. Of course, it is also feasible to use basalt fiber composites for the box body 101 and stainless steel or other materials for the lid 102. In this case, compared to the traditional method of welding multiple stainless steel sheets, it still has the effect of reducing the weight of the box 100 and reducing welding and shaping operations. In this embodiment, the box body 101 and the lid 102 are integrally formed. The specific forming process of the box body 101 and the lid 102 is described in detail in the following description of the manufacturing method of the box 100, and will not be repeated here.

[0072] To connect the box body 101 and the cover 102 together, in this embodiment, the edge of the box body 101 is provided with a flange 1011, and the cover 102 is connected to the flange 1011. The box body 100 also includes a sealing element, which is disposed between the flange 1011 and the cover 102. The flange 1011 here not only facilitates the connection between the box body 101 and the cover 102, but also enhances the structural strength of the box body 101. Moreover, the flange 1011 has a simple structure and is easy to process and form. Furthermore, by providing a sealing element, the sealing performance between the flange 1011 and the cover 102 in the connected state is improved, thereby improving the sealing performance of the box body 100.

[0073] As an optional implementation method, such as Figure 3 and Figure 4 As shown, the flange 1011 is along the inner edge of the top of the box body 101, and the cover 102 overlaps the flange 1011. The flange 1011 and the cover 102 can be riveted together. For example, the flange 1011 has a plurality of rivets 1012 spaced apart along its circumference, and the cover 102 has riveting holes 1021 through which each rivet 1012 passes. By installing the rivets 1012 in the corresponding riveting holes 1021, the cover 102 and the flange 1011 can be connected together.

[0074] It is understandable that, in addition to riveting, bolting can also be used to connect the flange 1011 and the cover 102. In this case, the bolt passes through the flange 1011 and the cover 102 and is connected to the nut, thus achieving the connection between the cover 102 and the flange 1011. This also facilitates the installation and removal of the cover 102 on the box body 101, thereby making it easier to inspect and maintain the internal structure of the box body 100. Here, the flange 1011 can be located not only on the inner edge of the top of the box body 101, but also on the outer edge of the top of the box body 101. In specific implementation, the position of the flange 1011 can be determined according to the requirements.

[0075] In some embodiments, the sealing element in this application embodiment may be a sealing ring made of rubber material, which is sandwiched between the flange 1011 and the cover 102. As the flange 1011 is connected to the cover 102, the sealing ring is compressed, thereby sealing the gap between the cover 102 and the flange 1011, thus ensuring the sealing effect at the connection between the cover 102 and the box body 101.

[0076] In other embodiments, the sealant is made of sealant. Specifically, the cover 102 and the flange 1011 are first joined together, and then sealant is filled into the gap between the cover 102 and the flange 1011. After the sealant cures, a sealant is formed. This also ensures a good seal at the connection between the cover 102 and the box body 101. Additionally, a basalt fiber composite layer can be bonded to the outer periphery of the connection between the flange 1011 and the cover 102 to further improve the connection and sealing effect.

[0077] In addition, to further improve the structural strength of the housing 100, such as Figure 3 and Figure 4 As shown, the bottom and sides of the box body 101 are respectively provided with first reinforcing protrusions 1013 protruding into the receiving cavity, and the cover 102 is also provided with second reinforcing protrusions 1022 protruding into the receiving cavity. The first reinforcing protrusions 1013 and the second reinforcing protrusions 1022 have simple structures, are easy to process and form, and provide good reinforcement of the box body 100. It is understandable that providing only the first reinforcing protrusions 1013 on the box body 101 is also feasible; in specific implementation, the number and position of each reinforcing protrusion can be adaptively adjusted according to requirements.

[0078] In some embodiments, mounting members 200 are provided on both the box body 101 and the cover 102 to facilitate the installation of the reinforcing components 300 on the box body 101 and the cover 102 respectively, thereby enabling structural reinforcement of the box body 101 and the cover 102 respectively, and further improving the overall structural strength of the box body 100.

[0079] The mounting component 200 in this embodiment includes a support portion 201 and at least one connecting portion 202 disposed on the support portion 201. The support portion 201 is connected to the outer surface of the housing body 101, and the connecting portion 202 is used to connect the reinforcing component 300. This not only facilitates the connection of the mounting component 200 to the housing body 100 and the cover 102, but also facilitates the installation of the reinforcing component 300 on the mounting component 200.

[0080] like Figure 5As shown, the connecting part 202 is a stud, and the mounting part 200 is a basalt fiber composite component. The mounting part 200 and the box body 101 are integrally formed, or the mounting part 200 is bonded to the box body 101. Here, the connecting part 202 uses a stud, which has the advantages of simple structure and easy installation and disassembly of the reinforcing component 300.

[0081] The mounting component 200 is preferably also a basalt fiber composite component, which helps to further reduce the weight of the housing 100. The support portion 201 is preferably plate-shaped, with one end of a stud pre-embedded in it. The number of studs can be determined according to usage requirements; for example, two, three, or four studs can be used. The plate-shaped support portion 201 increases the connection area between the mounting component 200 and the housing body 101 or cover 102, thereby improving the installation stability of the mounting component 200.

[0082] Since the mounting component 200 and the box body 101 are made of the same material, in practice, the mounting component 200 and the box body 101 can be integrally molded. In this case, only the thickness of the mounting component 200 needs to be increased. The mounting component 200 can also be installed on the box body 101 or the cover 102 by adhesive bonding, which also has the advantage of easy layout and implementation. Of course, it is also feasible to use stainless steel or other metal materials for the mounting component 200. After the mounting component 200 is bonded to the box body 100, a basalt fiber composite layer can be bonded at the connection between the mounting component 200 and the box body 100 to further improve the installation reliability of the mounting component 200.

[0083] As an optional implementation method, such as Figure 1 , Figure 2 and Figure 6 As shown in the illustration, the housing 100 in this embodiment further includes a reinforcing assembly 300, which comprises at least two first reinforcing members 301 and at least one second reinforcing member 302. The first reinforcing members 301 are sequentially spaced along the length of the housing body 101, located at the bottom of the housing body 101, and extending to two opposite sides of the housing body 101 along its length. The reinforcing assembly 300 is preferably made of a metal material, such as stainless steel, to provide better reinforcement.

[0084] Mounting members 200 are provided on the bottom and sides of the box body 101. The mounting members 200 are correspondingly connected to the first reinforcing members 301. The second reinforcing members 302 are located on at least one side of the box body 101 along its length. Mounting members 200 are provided on at least one side of the box body 101 along its length. The mounting members 200 are correspondingly connected to the second reinforcing members 302. The ends of each first reinforcing member 301 located on the same side of the box body 101 are connected to the second reinforcing member 302 on the same side.

[0085] With this configuration, the first reinforcing member 301 is connected to the box body 101 via the corresponding mounting member 200, thereby strengthening the bottom and sides of the box body 101. The second reinforcing member 302 is connected to the side of the box body 101 via the corresponding mounting member 200, which not only helps to further improve the strength of the side of the box body 101, but also connects the first reinforcing member 301 and the second reinforcing member 302 on the same side of the box body 101 by connecting the ends of each first reinforcing member 301 on the same side to the second reinforcing member 302 on the same side, thereby strengthening the reinforcing effect of the reinforcing assembly 300 on the box body 101.

[0086] In some embodiments, such as Figure 6 and Figure 7 As shown, three first reinforcing members 301 are arranged at intervals along the length of the box body 101, and the first reinforcing members 301 and the second reinforcing members 302 are respectively located on opposite sides of the length of the box body 101, thus making the entire first reinforcing member 301 U-shaped. Each second reinforcing member 302 on each side is connected to the first reinforcing member 301 on the same side. It can be understood that the number and position of the first reinforcing members 301 and the second reinforcing members 302 can be adaptively adjusted according to usage requirements.

[0087] To facilitate the installation of the first reinforcing member 301, such as Figure 8 As shown, the first reinforcing member 301 includes a first section 3011 located at the bottom of the box body 101, and a second section 3012 located on two opposite sides of the box body 101 along its length.

[0088] The first segment 3011 and the second segment 3012 are respectively provided with mounting holes 305 for corresponding studs to pass through. After the studs on the mounting member 200 pass through the corresponding mounting holes 305, the first reinforcing member 301 can be connected to the mounting member 200 by screwing them with the nut. To improve the connection effect, a washer can also be provided between the nut and the first reinforcing member 301. To further improve the flexibility of the first reinforcing member 301 during installation, the mounting hole 305 is preferably an oblong hole.

[0089] In some embodiments, the first reinforcing member 301 has a U-shaped cross-section, which helps to improve its structural strength. Of course, the cross-section of the first reinforcing member 301 can also be L-shaped or U-shaped, in which case the strength requirements of the first reinforcing member 301 can still be ensured. Figure 9 and Figure 10 As shown, the mounting members 200 used for mounting the same first reinforcing member 301 are preferably three, and are respectively set to correspond one-to-one with the first segment 3011 and the second segment 3012.

[0090] To further improve the performance of the first reinforcing member 301, in some embodiments, such as Figure 7 As shown, a first connecting plate 304 can also be provided on the outer side of the junction of the ends of the first segment 3011 and the second segment 3012. The first connecting plate 304 is L-shaped and is used to connect the first segment 3011 and the second segment 3012 together. The first connecting plate 304 is welded to the first segment 3011 and the second segment 3012 respectively, which has the advantages of easy installation and good strength enhancement.

[0091] In other embodiments, the ends of the first segment 3011 and the second segment 3012 are directly welded together, which also helps to improve the structural continuity and strength of the entire first reinforcing member 301. Furthermore, it is also feasible to connect the first segment 3011 and the second segment 3012 using bolts or other connecting structures. In this case, protruding connecting protrusions can be provided on both the first segment 3011 and the second segment 3012, and the bolt can pass through the two connecting protrusions and be connected to the nut.

[0092] like Figure 7 and Figure 8 As shown, the top end of the second segment 3012 is connected to the second reinforcing member 302. To achieve the connection between the two, connecting segments 30121 extending upward are provided on both sides of the top end of the second segment 3012. The connecting segments 30121 can overlap the outside of the second reinforcing member 302 and are connected to the second reinforcing member 302 by welding.

[0093] An exemplary structure of the second reinforcing member 302 in this application embodiment is as follows: Figure 11 As shown, the cross-section of the second reinforcing member 302 is "L" shaped, and the mounting member 200 corresponding to the second reinforcing member 302 preferably extends along the length direction of the housing body 101. The connection method between the second reinforcing member 302 and the stud is the same as the connection method between the first reinforcing member 301 and the stud, that is, the second reinforcing member 302 is provided with the aforementioned mounting hole 305 for the stud to pass through.

[0094] Here, the second reinforcing member 302 has the advantages of simple structure, easy layout and implementation, and good strength enhancement effect. It is understood that the cross-sectional shape of the second reinforcing member 302 can also be adaptively adjusted according to requirements. The mounting member 200 for mounting the second reinforcing member 302 also extends along the length direction of the housing body 101 to improve the installation reliability of the second reinforcing member 302.

[0095] like Figure 2 , Figure 6 and Figure 7As shown, the reinforcing component 300 also includes a third reinforcing member 303. A mounting member 200 is provided on the top of the cover 102, and the mounting member 200 on the top of the cover 102 is connected to the third reinforcing member 303. The two ends of the third reinforcing member 303 are respectively connected to the second reinforcing members 302 on the two sides of the box body 101 in the length direction.

[0096] Thus, by setting the third reinforcing member 303, the structural strength of the cover 102 is improved. The two ends of the third reinforcing member 303 are respectively connected to the second reinforcing members 302 on the two sides of the box body 101 along the length direction, so that the third reinforcing member 303, the second reinforcing member 302 and the first reinforcing member 301 are connected together to form a reinforcing frame for the box body 101, which helps to maximize the structural strength of the box body 100.

[0097] Specifically, such as Figure 12 As shown, the cross-section of the third reinforcing member 303 is also U-shaped. The connection method between the third reinforcing member 303 and the stud is the same as that between the first reinforcing member 301 and the stud, that is, the third reinforcing member 303 is provided with the aforementioned mounting hole 305 for the stud to pass through. Figure 7 and Figure 12 As shown, the third reinforcing member 303 has folded edges 3031 at both ends that fold towards the second reinforcing member 302 on the same side. The folded edges 3031 can overlap the second reinforcing member 302 and are connected to the second reinforcing member 302 by welding. Here, the position and number of the third reinforcing members 303 on the cover 102 can be adjusted according to usage requirements.

[0098] In this embodiment, the first reinforcing member 301 improves the strength of the bottom and sides of the box body 101, the third reinforcing member 303 improves the strength of the cover 102, and the second reinforcing member 302, while improving the strength of the sides of the box body 101, also connects the first reinforcing member 301 and the third reinforcing member 303 together, so that the first reinforcing member 301, the second reinforcing member 302 and the third reinforcing member 303 form a cage-like reinforcing assembly 300 to increase the strength of the box body 100. In addition, the cage-like reinforcing assembly 300 also improves the connection reliability between the cover 102 and the box body 101, and helps to constrain the cover 102 and the box body 101 together.

[0099] As an optional implementation, the housing 100 in this embodiment further includes at least one connector 400. The connector 400 has a support 401 connected to the top of the cover 102 and / or the housing body 101, and a connecting body 402 connected to the support 401. The connecting body 402 is used to connect the lifting member 500. By providing the connector 400, it is advantageous to connect the lifting member 500 to the top of the cover 102 and / or the housing body 101, thereby facilitating the lifting of the housing 100 onto an external mounting carrier, such as the body of a railcar.

[0100] like Figure 2 and Figure 13 As shown, the housing 100 also includes a lifting member 500; the lifting member 500 has a vertically arranged horizontal portion 501 and a vertical portion 502, and a lifting portion 503 connecting the horizontal portion 501 and the vertical portion 502, the lifting portion 503 being used to connect to an external carrier (the external carrier may be, for example, the body of a railcar). The support body 401 has a first portion 4011 corresponding to the horizontal portion 501, and a second portion 4012 corresponding to the vertical portion 502, the first portion 4011 being used to connect to the cover 102, the second portion 4012 being used to connect to the housing body 101, and connecting bodies 402 being respectively provided on the first portion 4011 and the second portion 4012.

[0101] Here, the first part 4011 on the support 401 is connected to the cover 102, and the second part 4012 is connected to the box body 101. These parts can be correspondingly arranged with the horizontal part 501 and the vertical part 502 on the lifting component 500, which helps improve the connection reliability of the connector 400 on the cover 102 and the box body 101, thereby ensuring the lifting stability of the box 100. Furthermore, the lifting component 500 can be made of stainless steel or other metal materials to provide good strength.

[0102] like Figure 13 As shown, the horizontal portion 501 and the vertical portion 502 are spaced apart. The lifting portion 503 includes two support plates 5031 arranged opposite each other along the width direction of the lifting component 500, and a lifting plate 5032 connected between the tops of the two support plates 5031. The two support plates 5031 are each L-shaped and welded to the outer surfaces of the horizontal portion 501 and the vertical portion 502, respectively, which helps to improve the overall structural strength of the lifting component 500. In addition, the lifting plate 5032 is provided with lifting holes 5033 to facilitate the lifting of the lifting component 500.

[0103] Accordingly, an exemplary structure of the connector 400 in this application embodiment is as follows: Figure 14As shown in the diagram, the first part 4011 and the second part 4012 are connected in an "L" shape. Both the first part 4011 and the second part 4012 are plate-shaped, and each has four connecting bodies 402, which helps to improve the connection strength between the connecting member 400 and the lifting member 500. The connecting body 402 here is also a stud, and the lifting member 500 has a through hole for the stud to pass through. The connecting body 402 has a simple structure, is easy to arrange and implement, and has a good connection effect.

[0104] In some embodiments, such as Figure 2 As shown, the lifting components 500 are respectively installed at the four corners of the top of the box body 100, and the connecting components 400 are correspondingly installed one-to-one with the lifting components 500. This helps to improve the structural stability of the box body 100 in the lifting state. In addition, provided that the layout space allows, a second connecting plate 403 can be installed between two connecting components 400 located at the same end of the box body 100. The two connecting components 400 at the same end are connected together by the second connecting plate 403, which also helps to improve the connection strength between the connecting components 400.

[0105] like Figure 2 As shown, the vertical portion 502 of the lifting component 500 can also overlap the second reinforcing member 302 and be welded to it. This allows the lifting component 500 to be connected to the reinforcing assembly 300, enabling the connecting member 400 and the lifting component 500 to work together with the reinforcing assembly 300 to improve the structural strength of the housing 100. Of course, the number and position of the lifting components 500 can also be adjusted according to usage requirements.

[0106] The housing 100 in this embodiment can be, for example, a sewage tank in a railcar sewage treatment device. The housing 100 also includes an inlet pipe 1014, a drain pipe 1023, and a vent pipe 1015, all connected to the receiving cavity. The inlet pipe 1014 is located on the cover 102 or the housing body 101 and is used to supply sewage into the receiving cavity. The drain pipe 1023 is located on the cover 102 or the housing body 101 and is used to discharge waste. The vent pipe 1015 is located on the cover 102 or the housing body 101 and is used to connect the receiving cavity to the outside atmosphere. This facilitates the inflow and outflow of waste in the housing 100.

[0107] like Figure 1 , Figure 2 and Figure 15 As shown, the sewage inlet pipe 1014 is located at one end of the box body 101, and the sewage outlet pipe 1023 is located at the other end of the cover 102 relative to the sewage inlet pipe 1014. This facilitates the inflow and outflow of sewage. The vent pipe 1015 passes through the bottom of the box body 101, and the top end of the vent pipe 1015 is spaced apart from the cover 102 to facilitate the discharge of gas in the containment cavity through the vent pipe 1015.

[0108] To facilitate the installation of the vent pipe 1015, an opening 1024 is provided on the cover 102, and the top end of the vent pipe 1015 is positioned corresponding to the opening 1024. A sealing cap 1025 for sealing the opening 1024 is provided on the cover 102. A connecting pipe 1018 is also provided at the end of the box body 101 away from the sewage inlet, and a control valve is provided on the connecting pipe 1018.

[0109] In practical implementation, the inlet pipe 1014 is connected to the transfer box 700 in the sewage treatment device, and the sludge in the transfer box 700 flows into the tank body 100 through the inlet pipe 1014. To facilitate the arrangement of the transfer box 700 and the wastewater tank 800 at one end of the tank body 100, as follows... Figure 16 As shown, each of the second reinforcing members 302 extends outward toward one end of the transfer box 700, and a "U"-shaped mounting bracket 601 is connected to the extended ends of the two reinforcing members. The bottom of the mounting bracket 601 is connected to the first reinforcing member 301 at the end of the box 100 through multiple third connecting plates 602, thereby connecting the mounting frame 600 and the reinforcing assembly 300 together. The mounting bracket 601 and the multiple third connecting plates 602 together form the mounting frame 600.

[0110] An installation space is formed between the housing 100, the mounting frame 600, the second reinforcing member 302, and the third connecting plate 602, and the transfer box 700 and the wastewater tank 800 are specifically installed in the installation space. Alternatively, the transfer box 700 and the wastewater tank 800 in this embodiment can also be made of basalt fiber composite to reduce the weight of the wastewater treatment device.

[0111] As an optional implementation method, such as Figure 15 As shown, the housing 100 also includes a rinsing pipe 1016 and a heating pipe 1019. The rinsing pipe 1016 is located on the cover 102 or the housing body 101, with at least a portion of the rinsing pipe 1016 situated within the receiving cavity. The rinsing pipe 1016 has a rinsing hole for connecting it to the receiving cavity. The heating pipe 1019 is located within the receiving cavity and is used to heat the contaminants within it. The rinsing pipe 1016 facilitates the spraying of water into the housing 100, thereby enabling thorough cleaning of the interior and extending the service life of the housing 100.

[0112] The flushing pipe 1016 is located on the housing body 101 and extends through both ends of the housing body 101 along its length. The portion of the flushing pipe 1016 located in the receiving cavity has multiple flushing holes. The flushing fluid in the flushing pipe 1016 is sprayed into the housing 100 through the flushing holes to clean the housing 100.

[0113] In this embodiment, the heating tube 1019 is located at the end of the box body 101 furthest from the sewage inlet pipe 1014. The heating tube 1019 is situated within the receiving cavity, facilitating the heating of the waste and achieving relatively good heating efficiency. Additionally, a temperature detection unit 1017 is located at the other end of the box body 101, relative to the heating tube 1019. The base of the temperature detection unit 1017 is connected to the box body 101, and the detection portion of the temperature detection unit 1017 is located within the receiving cavity. The temperature detection unit 1017 can employ a temperature sensor from the prior art.

[0114] Basalt composite fiber can be bonded to the connection points between the above-mentioned pipes and the housing 100. By using basalt composite fiber to seal the connection points between the pipes and the housing 100, it is also beneficial to provide sealing performance at the connection points.

[0115] To ensure the performance of the enclosure 100, a pressure test is required. During the procedure, only one water inlet is left open. The enclosure 100 is filled with water until the water pressure reaches the preset value. This pressure is maintained for a certain period, and then the exterior of the enclosure 100 is observed for any leaks. The pressure gauge reading for the pressure chamber is also observed to see if there is a drop in pressure. If there are no leaks and the pressure gauge does not drop, the enclosure 100 has passed the test. The preset water pressure and the pressure holding time can be set according to usage requirements. For example, the preset water pressure can be greater than or equal to 250 kPa and less than or equal to 350 kPa, and the pressure holding time can be greater than or equal to 20 minutes and less than or equal to 40 minutes.

[0116] In this embodiment, the housing 100 uses basalt fiber composites instead of stainless steel. Verification has shown that this reduces the weight of the housing 100 by more than 30%, thereby reducing the energy consumption of the railcar. The basalt fiber composites are pollution-free and can be recycled as building reinforcement materials, overcoming the high-pollution recycling bottleneck of traditional metal materials.

[0117] In addition, the thermal conductivity of basalt fiber composites is low, ranging from 0.03 to 0.04 W / (m·K). It has been verified that the heat loss of the box 1 in the embodiment of this application can be reduced by more than 30%, thereby achieving the effects of antifreeze and energy saving.

[0118] Basalt fiber composites exhibit high strength; verified results show that their tensile strength can reach 3800-4800 MPa, and their elastic modulus reaches 9100–11000 kg / mm². 2 It is superior to traditional glass fiber and aramid, which helps to ensure the performance of the enclosure 100. Furthermore, the enclosure 100 made of basalt fiber composites has outstanding performance in acid and alkali resistance, aging resistance and UV protection, especially in harsh environments (such as acid and alkali corrosion, high humidity).

[0119] The embodiments of this application also provide a method for manufacturing the box 100, such as... Figure 17 As shown, the steps include:

[0120] S101. A box body 101 is formed by setting basalt fiber composite material on a first mold. The box body 101 has a receiving cavity inside, and the top of the box body 101 has an opening communicating with the receiving cavity.

[0121] In this embodiment, step S101 produces an integrally formed box body 101, which is concave. To improve the structural strength of the box body 101, reinforcing protrusions can be provided on the bottom and sides of the box body 101. The number and position of the reinforcing protrusions can be determined according to the usage requirements.

[0122] S102, forming the cover 102 on the second mold.

[0123] The lid 102 obtained in step S102 is plate-shaped and its shape is adapted to the shape of the opening at the top of the box body 101 to facilitate connection with the box body 101 and seal the opening at the top of the box body 101. The lid 102 can be made of basalt fiber composite material, which helps to further reduce the weight of the box body 100. Of course, the lid 102 can also be made of metal materials such as stainless steel.

[0124] There is no specific order between steps S101 and S102. In specific operations, steps S101 or S102 can be performed first or simultaneously, depending on the requirements.

[0125] Step S103: A mounting member 200 is provided on the surface of at least one of the box body 101 and the cover 102. The mounting member 200 is used to connect and reinforce the reinforcing assembly 300 of the box body 101 or the cover 102.

[0126] The mounting component 200 can be installed on both the box body 101 and the cover 102, or it can be installed on only the box body 101 or the cover 102. The mounting component 200 has a plate-shaped support portion 201 and a connecting portion 202 provided on the support portion 201. When the mounting component 200 is made of basalt fiber composite material, it can be integrally formed with the box body 101 and the cover 102 of the same material, or it can be bonded to the formed box body 101 and the cover 102. Of course, the mounting component 200 can also be made of metal materials such as stainless steel, in which case the mounting component 200 is connected to the box body 101 and the cover 102 by bonding.

[0127] Step S104: Place the cover 102 on top of the box body 101 to seal the opening, connecting the box body 101 and the cover 102. The cover 102 and the box body 101 can be connected together by riveting or screwing. This method offers the advantages of simple connection and ease of operation.

[0128] The following explanation uses the riveting connection between the cover 102 and the box body 101 as an example. In this case, the edge of the box body 101 is provided with a flange 1011, and the cover 102 is connected to the flange 1011. Multiple rivets 1012 are respectively provided on the flange 1011, and the cover 102 is provided with riveting holes 1021 for the rivets 1012 to pass through. By riveting the rivets 1012 to the riveting holes 1021, the cover 102 and the box body 101 can be connected together.

[0129] In the first embodiment, step S101 includes step S1011, uniformly spraying a release agent onto the molding surface of the first mold.

[0130] Step S1012: Apply a layer of unsaturated resin evenly to the molding surface of the first mold.

[0131] Step S1013: Spread the prepared basalt fiber evenly on the surface of the unsaturated resin, and then coat the surface of the basalt fiber with a layer of unsaturated resin evenly.

[0132] Repeat steps S1012 and S1013 until the wall thickness of the basalt fiber composite material composed of multilayer basalt fiber and unsaturated resin reaches the target thickness of the box body 101.

[0133] Step S1014: Use a tool to smooth and flatten the surface of the box body 101, then proceed to the curing process. Once curing is complete, the box body 101 can be demolded to obtain the box body 101.

[0134] When the cover 102 is also a basalt fiber composite, the specific operation steps of step S102 and step S101 are the same, and will not be repeated here.

[0135] In the second embodiment, step S101 also includes steps S1011 to S1013 in the first embodiment, but the difference lies in step S1014. In step S1014 of the second embodiment, the cover 102 in the second mold and the box body 101 in the first mold are joined together.

[0136] It also includes step S1015, flattening the uncured box body 101 and lid 102, and then transferring them to the curing process. Once curing is complete, the box body 101 and lid 102 can be demolded to obtain the box body 101 and lid 102.

[0137] In the third embodiment, step S101 includes step S1011, uniformly spraying a release agent onto the molding surface of the first mold.

[0138] Step S1012: Spread the basalt fiber in multiple layers evenly onto the forming surface of the first mold according to the requirements, and lay a flow guide net or flow guide plate on the surface of the basalt fiber to form a resin flow channel.

[0139] One side of the guide net is connected to the glue inlet hose at one end of the first mold, and the hose is connected to the resin container. The other side of the guide net is connected to the suction hose at the other end of the first mold, and is connected to a vacuum pump.

[0140] Step S1013: Adhere a sealing strip around the forming surface of the first mold, and lay a layer of plastic film on the surface of the sealing strip. Adhere the plastic film around the sealing strip to prevent air leakage.

[0141] Step S1014: Start the vacuum pump. The vacuum pump extracts the air from the first mold, and the negative pressure inside will draw the resin into the mold. As the vacuum pump continues to work, the resin fills the entire molding part of the mold.

[0142] Step S1015: Close the glue inlet and vacuum pump, maintain negative pressure until the box body 101 is cured. Once cured, it can be demolded to obtain the box body 101.

[0143] In the manufacturing method of the box 100 in this embodiment, the box body 101 and the cover 102 can be obtained by the three molding methods in the above three embodiments. In specific implementation, the specific molding method can be selected according to the requirements, which has good manufacturing flexibility and is easy to operate and implement.

[0144] It should be noted that, during the actual manufacturing process, the cover 102 and the box body 101 can be connected together first, and then the mounting component 200 can be installed. The connection method between the cover 102 and the box body 101 can be riveting, or other connection methods that meet the connection requirements can be used.

[0145] The manufacturing method of the box 100 in this embodiment of the application further includes step S201, installing the sewage inlet pipe 1014, sewage outlet pipe 1023, vent pipe 1015, flushing pipe 1016 and heating pipe 1019 on the box 100.

[0146] In step S201, each pipe body can be made of stainless steel or other metal materials and connected to the housing 100 by adhesive bonding. Taking the installation of the drain pipe 1023 as an example, a connecting flange can be installed on the outer surface of the drain pipe 1023, and the flange can be bonded to the housing 100 for installation. To ensure the sealing effect at the connection between the drain pipe 1023 and the housing 100, basalt fiber composite material can also be bonded to the outer periphery of the flange, the connection between the drain pipe 1023 and the housing 100. Alternatively, sealant can be filled at the connection.

[0147] The method for manufacturing the enclosure 100 in this application involves using basalt fiber composite material to make the enclosure 100, and connecting the basalt fiber composite material enclosure 100 with reinforcing components 300 and lifting components 500 made of stainless steel or other metal materials. The resulting enclosure 100 not only conforms to the lightweight design concept, but also reduces welding steps and eliminates the need for shaping operations, while also meeting strength requirements and possessing good practicality.

[0148] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 therein. Such 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 this application.
