Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of carbon dioxide energy storage systems, and particularly relates to an integrated container assembly and application of the assembly in a carbon dioxide energy storage system. BACKGROUND

[0002] The carbon dioxide energy storage system refers to a novel, large-scale and long-time energy storage technology for realizing electric energy storage and release by using the phase change characteristics of carbon dioxide. The system has the advantages of high electric-electric conversion efficiency, large energy storage density, long service life and relatively low cost.

[0003] The working principle of the carbon dioxide energy storage system is mainly as follows: in the energy storage stage, carbon dioxide gas at normal temperature and pressure is compressed to a supercritical state by using off-peak electricity or wind-solar abandoned electricity, and the compression heat is stored by a heat storage medium, and the carbon dioxide is liquefied and stored in a high-pressure storage tank; in the energy release stage, the carbon dioxide in the high-pressure storage tank is heated and vaporized by a heater, enters a turbine expander to generate electricity, and the cold energy of the low-temperature heat storage medium is stored in a cold storage tank, and the carbon dioxide at the outlet of the last-stage turbine returns to the low-pressure storage tank.

[0004] Correspondingly, the existing common carbon dioxide energy storage system mainly includes a compression and expansion unit, a heat storage and heat exchange system, a gas storage, a sandwich cavity pressure regulating device, a circulation and pipeline system, a control system and auxiliary facilities.

[0005] The gas storage can be further divided into a rigid storage tank and a flexible membrane type gas storage. The former is used for storing high-pressure gaseous or supercritical carbon dioxide, and the latter is used for storing gaseous carbon dioxide at a lower pressure.

[0006] On the other hand, the structure of the flexible membrane type gas storage mainly includes an inner layer membrane and an outer layer membrane. The former is used for directly sealing and storing carbon dioxide, and the latter is mainly used for providing a structural support and external protection for the former.

[0007] Therefore, a sandwich cavity is formed between the inner layer membrane and the outer layer membrane, and the main function of the pressure regulating device is to adjust the pressure in the sandwich cavity by inflation and deflation, so as to maintain the shape stability of the outer layer membrane and indirectly protect the inner layer membrane.

[0008] Generally, the adjustment method is, for example:

[0009] In strong wind, the pressure is appropriately increased to prevent the outer layer membrane from shaking and tearing; in snow, the pressure is increased to lift the snow; in high temperature, the pressure is slightly adjusted to avoid the outer membrane being too tight; and in long-term shutdown, the minimum positive pressure is maintained to prevent collapse and avoid excessive extrusion of the outer layer membrane on the inner layer membrane.

[0010] In summary, the structural composition of the sandwich cavity pressure regulating device mainly includes the gas charging and discharging pipeline, the exhaust structure, and the air supply structure. The main defect of such a device in use is that the exhaust structure and the air supply structure are independent of each other and directly scattered, and the safety is relatively poor.

[0011] Therefore, the relatively safer such device generally includes the above-mentioned integrated container assembly in its structural composition. For example, the utility model patent with the authorization announcement number CN222027494U and the authorization announcement date of 2024.11.19 discloses a mobile air chamber internal pressure regulating device, which mainly includes a container, a control cabinet, an air supply structure, an exhaust structure, a solar photovoltaic panel, an external power supply box, a limiting hole plate, a door, and a louver.

[0012] The air chamber internal pressure regulating device in the utility model patent has the advantages and effects that the air supply structure and / or the exhaust structure can be pre-assembled in the factory, the degree of prefabrication of the product can be improved, the risks caused by uncontrollable factors in construction can be reduced, the installation efficiency can be improved, the amount of on-site construction can be reduced, and the project construction period can be shortened.

[0013] However, the air chamber internal pressure regulating device at least has the following problems of great manufacturing difficulty and insufficient installation stability in actual use, which specifically shows that:

[0014] First, the wire slot structure needs to be opened in the interior of the container, i.e., the interior of the container bottom plate. The manufacturing method has relatively great difficulty, has high requirements for the forming process of the container bottom plate, and greatly reduces the practicability;

[0015] Second, when the device is connected with the concrete foundation, the connection position is only at the limiting hole plate, which leads to the problem of relatively low connection strength, and the container structure is relatively easy to displace, such as wind displacement and bumping displacement. SUMMARY

[0016] The present application provides an integrated container assembly, which solves the technical problem of how to make the container structure of the sandwich cavity pressure regulating device have the convenience of wiring operation and the stability of installation operation.

[0017] In addition, the present application also provides an application of the above-mentioned container assembly in a carbon dioxide energy storage system.

[0021] Further preferred technical schemes are as follows: the air inlet and outlet cylinder unit further comprises a bolt mounting hole arranged on the guide plate and used for connecting the control cabinet when the guide plate is used vertically.

[0022] Further preferred technical schemes are as follows: when the container assembly is stored and transported, the vertical cylinder is inverted and arranged on an upper surface of the movable plate, and the bolt mounting hole and the wire hole are provided with a cylinder displacement prevention bolt.

[0023] Further preferred technical schemes are as follows: the air inlet and outlet cylinder unit further comprises a dual-purpose bolt arranged on the guide plate and used for connecting the vertical cylinder, and a support screw hole arranged on the guide plate and used for supporting the guide plate in an inclined state on an upper end surface of the vertical cylinder by mounting the dual-purpose bolt.

[0024] Further preferred technical schemes are as follows: when the container assembly is used, the wire hole and a bottom plate of the control cabinet are provided with a control cabinet reinforcing bolt; the wire hole is in a rectangular or oblong shape.

[0025] Further preferably, the movable cover plate unit further comprises a fixing bolt arranged on the movable plate and used for connecting the bottom plate of the box.

[0026] The carbon dioxide energy storage system has the structure of the integrated container assembly, and further comprises a concrete foundation for mounting the integrated container assembly, and the pipeline-concrete boss arranged on the concrete foundation and internally provided with a ventilation pipe and used for clamping the positioning hole.

[0027] Further preferably, the cross-sectional profile shape of the pipeline-concrete boss is circular or rectangular.

[0028] The beneficial effects of the present application include at least the following five points.

[0029] Firstly, the integrated opening pattern formed by the positioning hole and the opening for cable installation in the container assembly can stably install all the fan connecting lines without arranging the connecting lines inside the bottom plate of the box, so that the wiring operation has outstanding convenience and sufficient stability.

[0058] The following description is only a preferred embodiment of the present application, and does not limit the scope of the present application.

[0059] As shown in the accompanying drawings Figure 1 - the accompanying drawings Figure 10 As shown in the accompanying drawings, an integrated container assembly structure includes a box bottom plate 11 for forming a sandwich cavity pressure regulating device, further includes a positioning hole 1 arranged on the box bottom plate 11 and used for clamping a pipeline-concrete boss a, a cable installation opening 2 arranged on the box bottom plate 11 and communicating with the positioning hole 1 and used for installing a fan connecting line b, a ventilation cylinder unit 3 sleeved on the pipeline-concrete boss a and having a lower end surface abutting against an upper surface of the box bottom plate 11 and used for installing a fan c, and a movable cover plate unit 4 arranged on the upper surface of the box bottom plate 11 and clamping the cable installation opening 2 and used for covering the fan connecting line b and supporting a control cabinet d.

[0060] In the present embodiment, the structural components of the container assembly, for example, are:

[0061] 1 box bottom plate 11, 4 side plates 12, 1 top plate 13, 4 positioning holes 1, 5 cable installation openings 2, 4 ventilation cylinder units 3, and 3 movable cover plate units 4.

[0062] Among them, the main material of the container assembly is a high-strength weather-resistant steel with surface corrosion prevention treatment. The four positioning holes 1 are respectively located at four spaced positions formed by the five cable installation openings 2, and are communicated to form an overall bottom plate opening structure.

[0063] On the other hand, the "integrated" word refers to the container assembly, which can integrate multiple fans c, multiple control cabinets d, and various supporting electrical equipment in one box structure, thereby improving the use safety of the sandwich cavity pressure regulating device.

[0064] The container assembly plus fan c, control cabinet d, fan connecting line b, and various supporting electrical equipment such as lighting, emergency, etc., is the main part of the above-mentioned sandwich cavity pressure regulating device.

[0065] In addition, one fan c is installed in each of the air inlet and exhaust cylinder units 3, and the exhaust direction of the latter can be set to upward or downward, thereby effectively enabling the sandwich cavity pressure regulating function.

[0066] The movable cover plate unit 4 has at least the following three functions:

[0067] First, clamping the cable installation opening 2 to avoid the overall bottom plate opening structure from being deformed and broken due to excessive pressure;

[0068] Second, covering the fan connecting line b, including physical covering, preventing falling out, and electromagnetic shielding;

[0069] Third, assisting in reinforcing and supporting the control cabinet d.

[0070] Among them, the number of movable cover plate units 4 can be less than the number of cable installation openings 2, that is, not every cable installation opening 2 is provided with a fan connecting line b; the number of control cabinets d can be less than the number of movable cover plate units 4.

[0071] Finally, the reason why the container assembly has the advantage of convenient wiring operation is that the fan connecting line b does not need to be arranged inside the box bottom plate 11, but is accommodated and installed after the box bottom plate 11 is provided with an opening structure, so that the wiring operation of the fan connecting line b has sufficient stability and outstanding convenience, facilitating subsequent overall, maintenance, and maintenance operations on the fan connecting line b.

[0072] The reason why the container assembly has the advantage of stable installation is mainly:

[0073] First, the pipeline-concrete boss a is horizontally blocked and positioned in the hole 1, further avoiding harmful horizontal displacement of the box structure;

[0074] Second, the air inlet and exhaust cylinder unit 3 simultaneously clamps the pipeline-concrete boss a and presses down the box bottom plate 11, avoiding harmful upward displacement of the box structure;

[0075] Third, the box bottom plate 11 itself can also be connected to the concrete foundation e through a common bolt installation method, which can be shared with the first and second methods.

[0076] The air inlet and outlet cylinder unit 3 comprises a vertical cylinder 301, which is sleeved on the duct-concrete boss a, has the fan c inside, and is used to press down and fix the bottom plate 11 of the box body; and a guide plate 302, which is hingedly arranged on the vertical cylinder 301, and is used to blow and cool the control cabinet d by rotating upward to open and tilt to guide the air flow.

[0077] In the embodiment, the vertical cylinder 301 is a circular cylinder or a rectangular cylinder, which is matched with the shape of the duct-concrete boss a, and clamps the duct-concrete boss a in a clamping mode, such as transverse bolt clamping or inner side elastic rubber strip clamping.

[0078] At this time, one end of the ventilation pipe f is located between the inner layer film g and the outer layer film h, that is, in the interlayer cavity, and the other end is exposed at the duct-concrete boss a directly below the fan c. At least one of the fans c is set to blow upward, so that the pressure reduction operation of the interlayer cavity can be effectively performed. At least one of the fans c is set to blow downward, so that the pressure increase operation of the interlayer cavity can be effectively performed.

[0079] On the other hand, whether a torsion spring is arranged at the hinge of the vertical cylinder 301 and the guide plate 302 can ensure that the guide plate 302 can rotate as needed, and can fix the angle after rotation.

[0080] Generally, when the interlayer cavity pressure regulating device operates, the guide plate 302 is in a downward hanging state, which ensures that the air inlet and outlet passage of the vertical cylinder 301 is completely opened. For details, please refer to the rightmost air inlet and outlet cylinder unit 3 in the control cabinet d in FIG. 1. Figure 6

[0081] On the other hand, when the electrified equipment in the control cabinet d has heat dissipation needs, the air inlet and outlet cylinder unit 3 near the control cabinet d in the air outlet state can be set to the blow cooling state, that is, a small amount of air outlet efficiency is sacrificed, so that the air flow blows the above-mentioned electrified equipment. For details, please refer to the rightmost air inlet and outlet cylinder unit 3 in the control cabinet d in FIG. 1. Figure 8 .

[0082] The first use mode of the guide plate 302 is the normal state, and the rotating action of the guide plate 302 in the second use mode can be manually or automatically controlled, for example, a motor for driving the guide plate 302 to rotate can be arranged at the hinge of the guide plate 302 and the vertical cylinder 301. The motor is controlled by the above-mentioned electrified equipment, so as to ensure that the blow cooling function can be opened and closed as needed.

[0083] ​The movable cover plate unit 4 includes a movable plate 401 arranged on the upper surface of the box bottom plate 11 and used to cover the fan connecting line b, a deformation prevention limiting strip 402 arranged on the lower surface of the movable plate 401 and used to engage the cable installation opening 2, and a wire hole 403 arranged on the movable plate 401 and used to pass the fan connecting line b upward.

[0084] In the embodiment, the movable plate 401 is rectangular in shape, and is screwed and / or hinged with the box bottom plate 11. The former uses two groups of the above-mentioned fixed bolts 404, and the latter is a single-side hinged mode, which ensures that the movable plate 401 can be opened and has stability during horizontal installation, i.e., is not easy to spontaneously rotate and open upward.

[0085] The number of the deformation prevention limiting strips 402 is two, which are used to support and limit the cable installation opening 2, and avoid deformation and fracture of the box bottom plate 11 due to being pressed by a large force.

[0086] Finally, the wire hole 403 is rectangular or oblong in shape, so that:

[0087] First, a plurality of fan connecting lines b can pass through the wire hole 403;

[0088] Second, the remaining space after the fan connecting line b passes through the wire hole 403 can also be used to install a bolt, so that the above-mentioned support function is upgraded to support + screwing, and the installation stability of the control cabinet d is further improved.

[0089] The air inlet and outlet cylinder unit 3 further includes a bolt installation hole 303 arranged on the deflector 302 and used to connect the control cabinet d when the deflector 302 is used vertically.

[0090] In the embodiment, the bolt installation hole 303 is also rectangular or oblong in shape, so that the operation of installing a bolt and reinforcing the control cabinet d is more flexible.

[0091] Generally, the number of control cabinets d is one to two, and the number of air inlet and outlet cylinder units 3 is two or four. The control cabinet d is located between two adjacent air inlet and outlet cylinder units 3, so part of the deflectors 302 can be rotated upward to the vertical state to reinforce the control cabinet d, and the bolt installation holes 303 on the remaining air inlet and outlet cylinder units 3 can be directly idle.

[0092] When the container assembly is stored and transported, the vertical cylinder 301 is inverted and arranged on the upper surface of the movable plate 401, and the bolt installation hole 303 and the wire hole 403 are provided with a cylinder anti-displacement bolt.

[0093] In the embodiment, as shown in the attachedFigure 9 At this time, the flow guide plate 302 is below and the vertical cylinder 301 is above, corresponding to the inverted state described above.

[0094] Correspondingly, the other function of the bolt mounting hole 303, that is, after aligning the line hole 403, is used to install the cylinder anti-displacement bolt and its nut, to ensure that the assembly is not easy to roll and be damaged when stored and transported.

[0095] It should be noted that at this time, the flow guide plate 302 and the vertical cylinder 301 are relatively fixed, and the above-mentioned fixing effect can be provided by the torsion spring at the hinge of the two, or by the dual-purpose bolt 304.

[0096] At this time, the dual-purpose bolt 304 is screwed on the closing bolt slot 306 instead of the supporting screw hole 305. The closing bolt slot 306 and the supporting screw hole 305 are arranged in a staggered manner.

[0097] The air inlet and exhaust cylinder unit 3 further comprises a dual-purpose bolt 304 arranged on the flow guide plate 302 and used to connect the vertical cylinder 301, and a supporting screw hole 305 arranged on the flow guide plate 302 and used to support the flow guide plate 302 in an inclined state on the upper end surface of the vertical cylinder 301 by installing the dual-purpose bolt 304.

[0098] In this embodiment, the supporting screw hole 305 is provided with 3-10, thereby providing the flow guide plate 302 with multiple optional inclination degrees. When the dual-purpose bolt 304 is screwed into the supporting screw hole 305, its lower end can only abut against the upper surface of the vertical cylinder 301, and cannot be screwed with the vertical cylinder 301, so as to lift the flow guide plate 302.

[0099] Correspondingly, the vertical cylinder 301 is provided with a closing bolt slot 306, and when the dual-purpose bolt 304 is connected, the flow guide plate 302 is in a fixed horizontal state, and the container assembly is in a storage and transportation state.

[0100] On the other hand, when the container assembly is in use, the supporting screw hole 305 and the screw hole corresponding to the closing bolt slot 306 on the flow guide plate 302 can be connected and reinforced with the control cabinet d after the bolt mounting hole 303 is installed and bolted.

[0101] Correspondingly, the operation port of the control cabinet d is located at the side of a row of the air inlet and exhaust cylinder units 3, and therefore the effect of connecting the control cabinet d after the flow guide plate 302 is vertical does not affect the normal use of the control cabinet d.

[0102] The line hole 403 and the bottom plate of the control cabinet d are provided with control cabinet reinforcing bolts in use.

[0103] In the embodiment, the weight of the control cabinet d can be pressed on the box bottom plate 11 and the movable cover plate unit 4, and the screwing positions include the box bottom plate 11, the line hole 403, and the bolt mounting hole 303. Therefore, the control cabinet d has prominent mounting stability.

[0104] The movable cover plate unit 4 further includes fixing bolts 404 arranged on the movable plate 401 and used for connecting the box bottom plate 11.

[0105] In the embodiment, the two groups of fixing bolts 404 can provide screwing effects for the movable plate 401, or one group of fixing bolts 404 plus the hinge structure on one side, which can also make the movable plate 401 have the advantages of mounting stability and convenient opening and closing.

[0106] On the other hand, the line hole 403 is further provided with a cylinder anti-displacement bolt 405 and a nut thereof, which are used for fixing the exhaust and intake cylinder unit 3 in transportation or idle state. In use of the container assembly, the cylinder anti-displacement bolt 405 does not need to be removed, and does not affect the passing and mounting effect of the fan connecting line b, because the opening size of the line hole 403 is relatively large.

[0107] Generally, the two ends of the fan connecting line b are connected with the fan c and various electrified devices in the control cabinet d respectively, and the control cabinet d and the vertical cylinder 301 reserve appropriate line holes for the fan connecting line b.

[0108] A carbon dioxide energy storage system, the structure includes the integrated container assembly, further includes a concrete foundation e for mounting the integrated container assembly, and the pipeline-concrete boss a arranged on the concrete foundation e and internally provided with a ventilation pipe f and used for clamping the positioning hole 1.

[0109] In the embodiment, the structure of the carbon dioxide energy storage system includes the above-mentioned interlayer cavity pressure regulating device, the pipeline-concrete boss a, the concrete foundation e, the ventilation pipe f, the inner layer film g, and the outer layer film h.

[0110] The ventilation pipe f is embedded and poured in the concrete foundation e, one end of which is located in the interlayer cavity, and the other end is exposed on the pipeline-concrete boss a and located below the fan c.

[0111] In addition, the number of the ventilation pipes f is 2, one for air intake and pressure increase, and the other for air exhaust and pressure decrease, or the number is 1, and the shape is "Y", which is used with an electrically controlled three-way valve, and the pressure of the interlayer cavity can also be controlled.

[0112] The cross-sectional profile of the pipe-concrete boss a is circular or rectangular.

[0113] In the present embodiment, the flow guide plate 302 requires a suitable and fixed position for the functions of purge cooling control cabinet d and reinforcement control cabinet d. Therefore, the sleeve connection between the inlet and exhaust cylinder body unit 3 and the pipe-concrete boss a needs to have both active adjustable function and prohibition of spontaneous rotation function.

[0114] Therefore, the cross-sectional shape of the pipe-concrete boss a is circular or rectangular, and the vertical cylinder body 301 is fully clamped after being sleeved, so that spontaneous relative rotation between the two does not occur, and the multiple functions of the flow guide plate 302 can be effectively performed.

[0115] For example, if the cross-sectional shape of the pipe-concrete boss a is a right-angled triangle, then the vertical cylinder body 301 has only one installation position on it, and it is difficult to achieve both air-cooled control cabinet d and reinforced control cabinet d.

[0116] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the purpose of the present application. These are all non-creative modifications, and are protected by the patent law within the scope of the claims of the present application.
