[0064] The tank body 1 is provided with a manhole for workers to enter and exit, so as to inspect, maintain or clean the tank body 1. In this embodiment, the manhole is located at the axial end of the tank body 1. Specifically, the manhole is provided in the middle of one of the closure heads 12.

[0065] Figure 2 yes Figure 1 The enlarged structural diagram at A in the middle, Figure 3 Schematic diagram of the structure of the manhole cover structure 2 in this embodiment. Figure 4 for Figure 2 Schematic diagram of the local structure.

[0066] refer to Figure 1 to Figure 4 The manhole cover structure 2 is arranged at the manhole and is detachably connected to the tank body 1 for opening and closing the manhole.

[0067] In this embodiment, the manhole cover structure 2 includes a fixing tube 21 and a manhole cover 22 .

[0068] The fixing tube 21 is used to penetrate the manhole of the tank body 1 and is fixedly connected to the tank body 1 .

[0069] Specifically, the fixing tube 21 and the tank body 1 are fixed by welding.

[0070] In this embodiment, the interior of the fixing tube 21 is hollow and its two axial ends are open, that is, the fixing tube 21 is cylindrical, and when it is fixed at the manhole of the tank body 1, the inside and outside of the tank body 1 can be communicated. In addition, the fixing tube 21 extends inwardly into the tank body 1.

[0071] The manhole cover 22 is disposed on one axial side of the fixed cylinder 21 and is detachably connected to the fixed cylinder 21, so that the manhole cover 22 can be removed from the fixed cylinder 21 to open the opening of the fixed cylinder 21, or the manhole cover 22 can be connected and fixed to the fixed cylinder 21 to close the opening of the fixed cylinder 21.

[0072] In this embodiment, the manhole cover 22 includes a connecting ring 221 and a cover body 222 .

[0073] The connecting ring 221 is arranged on one axial side of the fixing tube 21 and is detachably connected to the fixing tube 21. Specifically, a plurality of connecting holes 223 are arranged at intervals along the circumferential direction on the connecting ring 221, and a plurality of fixing holes 211 are arranged on the fixing tube 21. The connecting holes 223 are arranged in a one-to-one correspondence with the fixing holes 211. A fastener is inserted into each connecting hole 223 and the corresponding fixing hole 211, and the fastener is used to realize the connection and fixation of the connecting ring 221 and the fixing tube 21.

[0074] The inner wall of the fixing hole 211 is provided with an internal thread, the inner wall of the connecting hole 223 is provided with an internal thread, and the outer periphery of the fastener is provided with an external thread. The internal thread and the external thread cooperate to achieve screw fixation between the fastener and the connecting ring 221 and the fixing cylinder 21.

[0075] Specifically, the fastener includes a rod body and a limiting body arranged at the end of the rod body. The outer circumference of the rod body is provided with an external thread. The outer diameter of the rod body is adapted to the inner diameter of the fixing hole 211. The outer diameter of the rod body is adapted to the inner diameter of the connecting hole 223, and can be inserted into the fixing hole 211 and the connecting hole 223. The limiting body extends outwardly beyond the rod body in the circumferential direction. The outer diameter of the limiting body is larger than the inner diameter of the connecting hole 223, and can abut against the connecting ring 221. The rod body passes through the connecting hole 223 and the fixing hole 211 in sequence, and is screwed with the connecting ring 221 and the fixing cylinder 21 at the same time. Moreover, the limiting body is pressed on the side of the connecting ring 221 away from the fixing cylinder 21, so as to further press the connecting ring 221 and the fixing cylinder 21.

[0076] In other embodiments, only the inner wall of the fixing hole 211 may be provided with an internal thread, and the connecting hole 223 may be a hole with a smooth inner wall. In this case, the rod body passes through the connecting hole 223 and extends into the fixing hole 211 to be threadedly connected with the fixing cylinder 21, and the limiting body is pressed on the side of the connecting ring 221 away from the fixing cylinder 21 to press the connecting ring 221 and the fixing cylinder 21 tightly.

[0077] The connecting ring 221 is sealed and connected to the fixing tube 21. Exemplarily, a sealing gasket 23 is provided between the connecting ring 221 and the fixing tube 21 to fill the gap between the connecting ring 221 and the fixing tube 21. Specifically, the sealing gasket 23 is open in the middle and is annular, and the sealing gasket 23 is fixed to one side of the connecting ring 221 close to the fixing tube 21.

[0078] In this embodiment, the connecting ring 221 is provided with a through hole 2211 which is in communication with the interior of the fixing tube 21. The inner diameter of the through hole 2211 is smaller than the inner diameter of the opening of the fixing tube 21. When the connecting ring 221 is connected to the fixing tube 21, the connecting ring 221 can protrude inwardly from the fixing tube 21 along the circumferential direction, and can cover a part of the opening of the fixing tube 21. The inside here refers to the direction toward the axis of the fixing tube 21.

[0079] At this time, the inner diameter of the middle opening of the sealing gasket 23 is smaller than the inner diameter of the opening of the fixed tube 21. When the sealing gasket 23 is connected to the fixed tube 21 along the connecting ring 221, the sealing gasket 23 can also protrude inwardly from the fixed tube 21 along the circumferential direction. That is to say, a part of the sealing gasket 23 can cover part of the opening of the fixed tube 21, and a part of it fits between the connecting ring 221 and the fixed tube 21, which can further improve the sealing performance between the connecting ring 221 and the fixed tube 21.

[0080] In other embodiments, the inner diameter of the middle opening of the sealing gasket 23 may also be greater than or equal to the inner diameter of the opening of the fixing tube 21 , and the specific setting depends on the needs.

[0081] In this embodiment, the outer circumference of the connecting ring 221 is flush with the outer circumference of the fixing tube 21. In other embodiments, the outer circumference of the connecting ring 221 may also extend outwardly beyond the outer circumference of the fixing tube 21 along the circumferential direction.

[0082] The cover 222 is disposed at the through hole 2211 of the connecting ring 221 and can protrude into the interior of the fixed cylinder 21, and the outer periphery of the cover 222 is fixedly connected to the connecting ring 221 and is sealed at the through hole 2211 of the connecting ring 221. Specifically, the cover 222 is fixedly connected to the side of the connecting ring 221 facing the fixed cylinder 21. At this time, the sealing gasket 23 is disposed around the outer periphery of the cover 222.

[0083] In this embodiment, the cross section of the cover body 222 is arc-shaped, and the convex surface of the arc faces the side away from the connecting ring 221. This design allows the cover body 222 to protrude into the fixing tube 21, and can increase its pressure resistance and improve its safety.

[0084] In this embodiment, the cover body 222 can be an elliptical head, a spherical head, or a dish-shaped head.

[0085] In this embodiment, a through hole communicating with the manhole is provided on the manhole cover structure 2. Specifically, the through hole is provided on the cover body 222 of the manhole cover 22.

[0086] In this embodiment, the manhole cover structure 2 may further include a connection seat 24, which is inserted into the through hole and fixedly connected to the cover body 222. Specifically, the connection seat 24 and the cover body 222 are fixed by welding, and a sealed connection between the connection seat 24 and the cover body 222 can be achieved to improve the sealing performance of the manhole cover structure 2.

[0087] The connecting base 24 defines an opening 241 communicating with the through hole 2211 .

[0088] In this embodiment, the manhole cover structure 2 further includes a mounting seat 25, which is inserted into the through hole and fixedly connected to the cover body 222. Specifically, the mounting seat 25 and the cover body 222 are fixed by welding, and a sealed connection between the mounting seat 25 and the cover body 222 can be achieved to improve the sealing performance of the manhole cover structure 2.

[0089] The mounting seat 25 is provided with a mounting hole 251 communicating with the through hole 2211 .

[0090] In other embodiments, the manhole cover structure 2 may include only the mounting seat 25 or only the connecting seat 24 .

[0091] In this embodiment, the electrical components are arranged on the manhole cover structure 2 and are detachably connected to the manhole cover structure 2. The electrical components extend into the tank body 1 to detect the signals inside the tank body 1. This design facilitates the removal of the electrical components from the manhole cover structure 2, and the electrical components are inspected, maintained, replaced, etc. Alternatively, the above design facilitates the integrated installation of the electrical components on the manhole cover structure 2, and the electrical components are directly installed on the tank body 1 using the manhole cover structure 2. At this time, the manhole can be used for the staff to enter and exit the tank body 1, and the electrical components can also be extended into the tank body 1. That is, the manhole is used for multiple purposes without the need to open additional holes for installing electrical components on the tank body 1 of the storage tank 120, so as to reduce the number of openings on the tank body 1 of the storage tank 120, and ensure the structural strength of the tank body 1 as a pressure vessel, thereby improving the safety performance of the storage tank 120.

[0092] In this embodiment, the electrical component can be connected to the cover body 222 through the connection seat 24. Specifically, the electrical component passes through the opening 241 on the connection seat 24 and is connected and fixed to the connection seat 24. Exemplarily, the inner peripheral wall of the opening 241 is provided with an internal thread, and the electrical component is correspondingly provided with an external thread, and the electrical component and the connection seat 24 are screwed together through the internal thread and the external thread.

[0093] Alternatively, the electrical component can also be connected to the cover body 222 through the mounting seat 25. Specifically, a plurality of threaded holes are provided at intervals along the circumferential direction on the mounting seat 25, and a locking member is correspondingly provided in each threaded hole, which is used to connect and fix the mounting seat 25 and the electrical component. Specifically, the inner circumferential wall of the threaded hole is provided with an internal thread, and the outer circumference of the locking member is provided with an external thread, and the internal thread and the external thread cooperate to achieve the screw connection and fixation of the locking member, the mounting seat 25, and the electrical component. Among them, the structure of the locking member can refer to the relevant description of the structure of the fastener in the above text, and the connection between the locking member and the mounting seat 25 and the electrical component can refer to the description of the connection between the fastener and the connecting ring 221 and the fixing cylinder 21 in the above text, which will not be repeated here.

[0094] In this embodiment, the electrical components may be components such as a float liquid level detector, a fixed liquid level detector, a temperature detector, and a pressure detector.

[0095] Among them, the signal inside the tank body 1 mentioned above can be a liquid level signal detected in real time by a float liquid level detector, a fixed liquid level signal detected by a fixed liquid level detector, a temperature signal detected by a temperature detector, or a pressure signal detected by a pressure detector, etc.

[0096] In this embodiment, the electrical component includes an instrument portion and an inner extension portion 31 .

[0097] The instrument part is detachably connected to the manhole cover structure 2 and is located outside the manhole cover structure 2. This design allows the staff to disassemble the instrument part without entering the tank body 1 when the instrument part needs to be inspected, maintained or replaced, which is convenient and simple to operate.

[0098] Specifically in this embodiment, the instrument part can be detachably connected to the cover body 222 through the connecting seat 24, and can also be detachably connected to the cover body 222 through the mounting seat 25. And the instrument part is located on the concave surface of the cover body 222. This design allows the staff to disassemble the instrument part without entering the tank body 1 when the instrument part needs to be inspected, maintained or replaced, and the operation is convenient and simple. In addition, the concave surface of the cover body 222 forms a shielding space to accommodate the instrument part, which can protect the instrument part.

[0099] Exemplarily, the float liquid level detector can be detachably connected to the cover body 222 via the mounting seat 25 , and the fixed liquid level detector, temperature detector, and pressure detector can all be connected to the cover body 222 via the connecting seat 24 .

[0100] refer to Figure 1 , Figure 2 The inner extension portion is used to extend into the interior of the tank body 1.

[0101] The inner extension part 31 is connected to the instrument part for communication, and is used to detect the signal inside the tank body 1, and then transmit and display the detected signal on the instrument part for the staff to view.

[0102] The inner extension part 31 can be fixedly connected to the connection seat 24, or can be detachably connected to the mounting seat 25 together with the instrument part. The inner extension part 31 can be fixedly connected to the connection seat 24, or can be detachably connected to the mounting seat 25 together with the instrument part.

[0103] In this embodiment, the inner extension portion 31 is a tubular structure with a certain length.

[0104] In this embodiment, the inner extension portion 31 includes a first pipe section 311, a second pipe section 312 and a third pipe section 313.

[0105] The second pipe section 312 of the inner extension part 31 is inclined to facilitate the inner extension part 31 to extend into the tank body 1 through the fixing tube 21. That is, this design facilitates the installation of the manhole cover 22 with the inner extension part 31 and the fixing tube 21, and also facilitates the disassembly.

[0106] refer to Figure 2, Figure 4 The support assembly includes at least two first support members 41 fixedly connected to the inner side of the manhole cover structure 2. Specifically, the first support member 41 is connected to the convex surface of the cover body 222, and when the manhole cover 22 covers the opening of the fixing cylinder 21, the first support member 41 is located inside the tank body 1.

[0107] At least two first support members 41 enclose and form a containing space that communicates with the through hole and the inside of the tank body 1, for allowing electrical components to pass through and for supporting and limiting electrical components. Specifically, at least two first support members 41 cooperate to support and limit the first pipe section 311 of the inner extension 31. At this time, the first pipe section 311 is arranged in the containing space and the through hole along the axial direction of the tank body 1.

[0108] In this embodiment, the first support member 41 can also be fixedly connected to the inner extension portion 31 to strengthen the support and limiting effect on the inner extension portion 31, thereby fixing the position of the inner extension portion 31 and strengthening the stability of the inner extension portion 31. Specifically, the first support member 41 is welded to the first pipe section 311 of the inner extension portion 31.

[0109] In other embodiments, the first support member may also abut against the inner extension portion 31 so that the inner extension portion 31 can be separated from the accommodating space, and when the inner extension portion 31 is detachably connected to the cover body 222, the inner extension portion 31 can simultaneously withdraw from the accommodating space and be removed from the cover body 222 to facilitate inspection, maintenance, cleaning, etc. of the inner extension portion 31.

[0110] In this embodiment, the first support member 41 gradually approaches the axis of the through hole in the direction away from the cover body 222, that is, the first support member 41 is inclined, so that any two first support members 41 can form a triangular structure. This design can improve the stability of the support assembly composed of multiple first support members 41, thereby improving the strength and stability of the support for electrical components.

[0111] In other embodiments, the support assembly may also be a cylindrical structure with two opposite ends connected.

[0112] In this embodiment, the support assembly may further include a second support member 42 .

[0114] refer to Figure 1 , Figure 2 and Figure 5 , the second support member 42 is arranged inside the tank body 1 and fixedly connected to the inner wall of the tank body 1. Specifically, the second support member 42 is located at one end of the tank body 1 close to the manhole, and the second support member 42 is fixed to the top of the tank body 1.

[0115] The second support member 42 is provided with a support hole, the axial direction of the support hole is consistent with the axial direction of the tank body 1, and the support hole is used to allow the electric component 31 to pass through, and is used to support and fix the electrical component 31. At this time, the second support member 42 cooperates with the first support member 41, increasing the support points for the electrical component, and can further enhance the stability of the electrical component to avoid damage to the electrical component due to external forces such as bumps during the movement of the storage tank 120, thereby ensuring the safety of the electrical component and ensuring its normal use. Specifically, the second support member 42 is used to support the third pipe section 313 of the inner extension of the fixed electrical component.

[0116] In this embodiment, the support hole is located above the through hole. At this time, the third pipe section 313 of the inner extension part 31 is arranged in the support hole along the axial direction of the tank body 1. Since the second pipe section 312 of the inner extension part 31 is arranged in an inclined manner, it is convenient for the inner extension part 31 to extend into the tank body 1 through the fixing tube 21, and it is convenient for the third pipe section 313 to penetrate into the support hole located above the manhole.

[0117] The position of the support hole inside the tank body 1 is determined according to needs and is not limited here.

[0118] In this embodiment, the second support member 42 includes a support plate 421 and a reinforcing plate 422.

A guide hole 431 is provided on the guide member 43, and the inner diameter of the guide hole 431 gradually decreases in the direction away from the manhole, and is used to guide the inner extension 31 of the electrical component. Since the inner extension 31 needs to be inserted into the support hole of the second support member 42 during the connection between the manhole cover 22 with the inner extension 31 and the fixing cylinder 21, the process is a blind installation process. At this time, the design of the guide hole 431 of the guide member 43 can guide the insertion of the inner extension 31, and facilitate the successful and rapid installation of the inner extension 31, and the operation is convenient and simple.

[0120] The inner extension 31 is sleeved with a buffer 44, which is used to contact the guide 43 to buffer the inner extension 31, so as to prevent the inner extension 31 from being damaged or making noise due to collision with the guide 43 due to external forces such as bumps during the movement of the storage tank 120, so as to achieve the purpose of noise reduction. Specifically, the buffer 44 is sleeved on the third pipe section 313.

[0121] In this embodiment, the buffer member 44 may be a flexible structure such as a rubber sleeve.

[0122] The connection method of the manhole cover structure 2, the electrical components and the tank body 1 is as follows:

[0123] First, a manhole is opened on the tank body 1, and the fixing tube 21 of the manhole cover structure 2 is inserted into the manhole in a manner that its axial direction is consistent with the axial direction of the tank body 1, and the fixing tube 21 is fixedly connected to the tank body 1 by welding.

[0124] Then, according to the number of electrical components required to be installed in the storage tank 120, through holes are opened on the cover 222, and the through holes are arranged one by one with the electrical components. According to the structure of the electrical components, the connection seat 24 and / or the mounting seat 25 are selected to be installed corresponding to a through hole, and the connection seat 24 and / or the mounting seat 25 are welded and fixed to the cover 222.

[0125] The electrical component is detachably connected to the connection base 24 in the form of its instrument part being located on the concave surface of the cover body 222. One end of the inner extension part 31 of the electrical component is extended into the opening 241 of the connection base 24, and the inner extension part 31 is fixedly connected to the connection base 24. Support components are arranged at intervals along the circumference of the inner extension part 31 on the connection base 24 and / or the cover body 222 to strengthen the support of the inner extension part 31. A buffer 44 is sleeved on the third pipe section 313 of the inner extension part 31.

[0126] Alternatively, the electrical component is detachably connected to the mounting seat 25 with its instrument portion located on the concave surface of the cover body 222, and one end of the inner extension portion 31 extends into the mounting hole 251 of the mounting seat 25 and is connected to the instrument portion.

[0127] A second support member 42 is arranged inside the tank body 1 , a guide member 43 is fixed in the support hole of the second support member 42 , and a guide hole 431 with an inner diameter gradually decreasing in a direction away from the through hole is arranged on the guide member 43 .

[0128] The manhole cover 22 with the electrical components installed thereon is connected and fixed to the fixing tube 21 by means of fasteners, and the inner extension portion 31 of the electrical components is extended into the interior of the tank body 1 .

[0129] In the case where the inner extension portion 31 of the electrical component needs to pass through the guide hole 431 of the guide member 43 on the support plate 421, the process is a blind installation process, and it is necessary to fully utilize the inclined design of the second pipe section 312 of the inner extension portion 31 and the structure of the guide hole 431 to successfully and quickly complete the installation of the inner extension portion 31.

The storage tank 120 is arranged on the vehicle body 110, and the vehicle body 110 is used to transport the storage tank 120.

[0132] It can be seen from the above technical solution that the utility model has at least the following advantages and positive effects:

[0133] The present application sets a support assembly to support the part of the electrical component located inside the tank body to increase the force points of the electrical component. This can prevent the electrical component from being damaged due to the shaking of the tank body during transportation, which would affect the inspection work of the electrical component. The stability of the electrical component can then be improved to ensure the safety of the electrical component.

[0134] In addition, the present application provides through holes on the cover body of the manhole cover for installing and fixing electrical components, so that when the manhole on the tank is used to install the manhole cover structure, the electrical components can also be directly installed. That is to say, the present application concentrates the through holes for installing and fixing electrical components at the manhole, and the manhole is used for multiple purposes without the need to provide additional holes on the tank for installing electrical components, so as to reduce the number of openings on the tank, thereby increasing the safety of the tank.
