Abstract
Description
Technical Field
[0001] The utility model relates to a GIS air chamber shell, in particular to a high-strength air chamber shell. Background Art
[0002] The construction of substations is carried out according to the forecast of power load demand and planning and design, usually in phases, so substations will inevitably face the situation of equipment expansion. Gas insulated switchgear (GIS equipment) is a typical equipment used in substations. The advantages of GIS are compact structure, small footprint, high reliability, flexible configuration, easy installation, strong safety, strong environmental adaptability, small maintenance workload, small maintenance intervals for its main components, and GIS gas chambers are all made of special gas chamber shells.
[0003] After the GIS equipment is shipped from the factory to the site designated by the customer, the corresponding equipment will be directly installed. Since the corresponding equipment has not been installed in the shell during transportation, and even the pressure gauge cannot be installed due to the matching holes on the shell for the equipment to be installed, it is impossible to ensure whether the GIS equipment meets the pressure requirements during on-site work. Once the equipment is partially deformed during transportation, it will greatly affect the pressure resistance of the equipment, and it is easy to leak during the use of the entire air chamber. Once leaking, it will not only affect the use of the equipment, but the leaked gas may also easily cause pollution.
[0004] Therefore, this case aims to provide a high-strength air chamber shell, which not only enhances its own strength and improves its ability to resist deformation during transportation, but also can detect whether the shell is deformed during transportation through mechanical detection, so that it can detect whether the shell is deformed during transportation through mechanical monitoring. Utility Model Content
[0005] The utility model provides a high-strength air chamber shell, which can effectively solve the above problems.
[0006] The utility model is achieved in this way:
[0007] A high-strength air chamber shell, comprising: an outer chamber shell, the outer chamber shell consisting of an outer mounting portion and an outer connecting portion, and further comprising:
[0008] The external reinforcement structure includes a top reinforcement member arranged on the top of the external mounting portion and the external connecting portion, a side mounting portion located on both sides of the external mounting portion and the external connecting portion, a multi-stage mounting member fixedly connected to a side of the external mounting portion away from the external connecting portion, and a bottom splicing member locked at the bottom of the external mounting portion;
[0009] The internal detection structure includes a support column locked and fixed at the bottom of the external mounting part, a transverse frame fixedly connected to the bottom of the support column and close to the center point of the inner wall of the external mounting part, the transverse frame is hollow, and pressure-blocking frames are slidably embedded in the openings on both sides of the transverse frame. A pressure-sensing structure extending to the pressure-blocking frame is arranged inside the transverse frame, and when the external mounting part or the external connecting part is subjected to an inward extrusion force, the pressure-blocking frame will squeeze the pressure-sensing structure.
[0010] As a further improvement, the top reinforcement member includes a top mounting frame welded to the top of the external mounting portion and the external connecting portion, and a plurality of brackets disposed on both sides of the top mounting frame and welded to the top of the external mounting portion and the external connecting portion.
[0011] As a further improvement, the top mounting frame includes two connecting plates welded to the tops of the external mounting portion and the external connecting portion, and connecting ribs connected between the connecting plates.
[0012] As a further improvement, the side mounting portion includes a plurality of U-shaped buckle frames welded to the sides of the outer mounting portion and the outer connecting portion, and the U-shaped buckle frames are arranged at equal intervals.
[0013] As a further improvement, the multi-stage mounting member includes two inward-turning frames welded to the side of the outer mounting portion away from the outer connecting portion, the inward-turning frame is a U-shaped frame, and long grooves are provided on opposite sides of the two inward-turning frames, and the positions of the two inward-turning frames where no long grooves are provided are connected by a transverse rod.
[0014] As a further improvement, the bottom splicing piece includes a plurality of cross-shaped frames welded to the bottom of the external mounting portion, and a connecting plate welded to the bottom of the cross-shaped frames, and threaded holes are formed on the connecting plate.
[0015] As a further improvement, the pressure-sensing structure includes a pressure-sensing part arranged in a cross structure and located inside the transverse frame, and a sensing tube inserted in the pressure-blocking frame. The pressure-sensing part includes a longitudinal portion and a transverse portion. The two ends of the inner side of the pressure-blocking frame abut against the lateral direction of the longitudinal portion, and the sensing tube abuts against the transverse portion after the pressure-blocking frame is pressurized.
[0016] The beneficial effects of the utility model are:
[0017] The utility model increases the outer side of the entire outer chamber shell in all directions by adding an external reinforcement structure, arranging a top reinforcement piece, a bottom splicing piece, a multi-stage mounting piece and a side mounting part on the top, bottom, forward direction and side direction of the outer chamber shell, thereby improving the safety of the GIS air chamber shell during transportation. Even when stacked and close to other shells, the shell is not easily deformed, thereby avoiding the deformation of the shell during transportation.
[0018] Even after the shell is transported to the destination, the above structure can be directly used as an external reinforcement component of the shell, thereby enhancing the strength of the air chamber and further improving the pressure-bearing capacity of the air chamber when it is pressurized.
[0019] Since matching holes need to be opened on the outer chamber shell for subsequent equipment installation, even if a gas sensor or a pressure sensor is installed, it cannot have any detection effect, which results in the workers having to conduct a comprehensive flatness test on the equipment after it arrives at the destination, so as to avoid traveling to a deformed location. In this regard, the utility model proposes to set an internal detection structure on the inner side of the outer chamber shell. The internal detection structure, which is locked and fixed, can be close to the center point of the inner wall of the outer mounting part. Once the shell is concave during transportation, it will always vibrate and react to the center point of the inner wall of the outer mounting part, causing thrust to the center point of the inner wall of the outer mounting part, so that the pressure retaining frame touches the pressure-sensing structure, thereby being able to sensitively sense whether the outer chamber shell is deformed. It is not affected by whether the shell is sealed, and only targets the sinking force that can be received, and is suitable for more complex scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0028] Reference Figure 1 to Figure 5 As shown, a high-strength air chamber shell comprises: an outer chamber shell 10, the outer chamber shell 10 is composed of an outer mounting portion 11 and an outer connecting portion 12, and is characterized in that it also comprises: an outer reinforcement structure, comprising a top reinforcement member 21 arranged on the top of the outer mounting portion 11 and the outer connecting portion 12, a side mounting portion 22 located on both sides of the outer mounting portion 11 and the outer connecting portion 12, a multi-stage mounting member 23 fixedly connected to the side of the outer mounting portion 11 away from the outer connecting portion 12, and a bottom splicing member locked at the bottom of the outer mounting portion 11 24; The internal detection structure includes a support column 31 locked and fixed at the bottom of the external mounting portion 11, a transverse frame 32 fixedly connected to the bottom of the support column 31 and tightly attached to the center point of the inner wall of the external mounting portion 11, the transverse frame 32 is hollow, and a pressure-blocking frame 33 is slidably embedded in the openings on both sides of the transverse frame 32, and a pressure-sensing structure 34 extending to the pressure-blocking frame 33 is arranged in the transverse frame 32. When the external mounting portion 11 or the external connecting portion 12 is subjected to an inward extrusion force, the pressure-blocking frame 33 will squeeze the pressure-sensing structure 34.
[0029] Since the uses and scenarios of the air chambers are different, the shapes of the air chambers are different. During transportation, the air chambers are stacked or close together. In this embodiment, the outer chamber shell 10 can be divided into two parts according to the appearance, namely, an external mounting part 11 and an external connecting part 12. The external mounting part 11 is used to install electrical equipment, and the external connecting part 12 is used to connect with other air chambers and air sources.
[0030] In this embodiment, a top reinforcement piece 21, a bottom splicing piece 24, a multi-stage mounting piece 23 and a side mounting portion 22 are respectively arranged on the top, bottom, forward direction and side direction of the outer chamber shell 10, so as to increase the outer side of the entire outer chamber shell 10 in all directions, thereby improving the safety of the GIS air chamber shell during transportation. Even when stacked and close to other shells, the shell is not easily deformed, thereby avoiding possible deformation of the shell during transportation.
[0031] Since the top of the outer chamber shell 10 not only requires a reinforced structure, but is also often connected to other structures or air chambers, the top reinforcement 21 is not only a supporting structure. Specifically: the top reinforcement 21 includes a top mounting frame 211 welded to the top of the outer mounting portion 11 and the outer connecting portion 12, and a plurality of tripods 212 arranged on both sides of the top mounting frame 211 and welded to the top of the outer mounting portion 11 and the outer connecting portion 12. In this embodiment, there are four tripods 212, which are respectively arranged at the four corners of the top mounting frame 211, and can be locked with other structures. At the same time, it also prevents the top mounting frame 211 from being directly pushed up by other structures. Even if other structures are pushed up, there are top mounting frames 211 to support it. Preferably, the top mounting frame 211 includes two connecting plates 2111 welded to the top of the outer mounting portion 11 and the outer connecting portion 12, and connecting ribs 2112 connected between the connecting plates 2111 and the connecting plates 2111. The parallel connecting ribs 2112 can support other structures that sink, thereby greatly avoiding deformation of the shell.
[0032] On the side, since the air chamber shells are mostly in close contact and have less matching relationships, it is sufficient to use a side mounting portion 22 with a single structure for separation. Specifically, the side mounting portion 22 includes a plurality of U-shaped buckle frames 221 welded on the sides of the outer mounting portion 11 and the outer connecting portion 12. The U-shaped buckle frames 221 are arranged at equal intervals and can be separated by U-shaped buckle frames 221 with a certain thickness.
[0033] On the front side of the external mounting portion 11, since electrical components need to be arranged inside the external mounting portion 11, it is necessary to arrange a reinforcement member here. However, due to the unique shapes of the external mounting portion 11 and the external connecting portion 12 in this embodiment, if too many or too heavy reinforcement structures are arranged on the front side of the external mounting portion 11, the shell may not be able to stand normally. Therefore, the multi-stage mounting member 23 of this embodiment includes two inward-turning frames 231 welded to the side of the external mounting portion 11 away from the external connecting portion 12. The inward-turning frames 231 are U-shaped frames, and long grooves are provided on the opposite sides of the two inward-turning frames 231. The positions of the two inward-turning frames 231 without long grooves are connected by a transverse rod 232. While the strength is enhanced by the inward-turning frames 231 and the transverse rod 232, the long grooves arranged at intervals can prevent the reinforcement structure at this location from being too heavy, thereby affecting the counterweight in two directions.
[0034] The bottom splicing piece 24 is based on the same principle as the top reinforcement piece 21, and is also first connected to other structures through a part of the connecting structure to further achieve the effect of enhanced protection. Specifically, the bottom splicing piece 24 includes a plurality of "X" frames 241 welded to the bottom of the outer mounting portion 11, and a connecting plate 242 welded to the bottom of the "X" frames 241. The connecting plate 242 is provided with a threaded hole 243, which is connected to other structures through the connecting plate 242 and the threaded hole 243, and the shell itself is protected by the "X" frames 241.
[0035] Even after the shell is transported to the destination, the above structure can be directly used as an external reinforcement component of the shell, thereby enhancing the strength of the air chamber and further improving the pressure-bearing capacity of the air chamber when it is pressurized.
[0036] Since matching holes need to be opened on the outer chamber shell 10 for subsequent equipment installation, even if a gas sensor or a pressure sensor is installed, it cannot have any detection effect, resulting in the need for workers to conduct a comprehensive flatness test on the equipment after it arrives at the destination, so as to avoid traveling to a deformed location. In this regard, the utility model proposes to set an internal detection structure on the inner side of the outer chamber shell 10. The internal detection structure, which is locked and fixed, can be tightly attached to the center point of the inner wall of the outer mounting part 11. Once the shell is concave during transportation, it will always vibrate and react to the center point of the inner wall of the outer mounting part 11, causing thrust to the center point of the inner wall of the outer mounting part 11, so that the pressure retaining frame 33 touches the pressure sensing structure 34, thereby being able to sensitively sense whether the outer chamber shell 10 is deformed. It is not affected by whether the shell is sealed, and only targets the sinking force that can be received, and is suitable for more complex scenarios.
[0037] The specific composition and principle of the pressure-sensing structure 34 are as follows: the pressure-sensing structure 34 includes a pressure-sensing member 341 arranged in a cross structure and located inside the transverse frame 32, and a sensing tube 342 inserted into the pressure-blocking frame 33. The pressure-sensing member 341 includes a longitudinal portion 3411 and a transverse portion 3412. The two ends of the inner side of the pressure-blocking frame 33 abut against the lateral direction of the longitudinal portion 3411. The sensing tube 342 abuts against the transverse portion 3412 after the pressure-blocking frame 33 is compressed. In fact, the pressure-sensing member 341 is a fixed piezoelectric material and is connected to an external signal source. When the U-shaped pressure-blocking frame 33 is fixed, When it is stationary, it will not affect the pressure-sensitive part 341. Once the shell is deformed and the pressure-blocking frame 33 is activated, the pressure-blocking frame 33 will preferentially touch the longitudinal portion 3411, so that the pressure-sensitive part 341 will output a pressure signal to an external signal source, prompting the staff that the shell is sunken. Once the transverse portion 3412 is squeezed by the sensing tube 342, it means that the shell here is sunken to a large extent and has reached a dangerous situation where it cannot be used. The signal sent by the pressure-sensitive part 341 is for emergency consumption. At this time, the staff can also observe it with the naked eye if they look carefully, thereby avoiding putting the shell into use when it is greatly deformed.
[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
