These manholes not only need excellent sealing and safety but also require an efficient and convenient opening and closing mechanism for rapid opening and closing in emergency situations.
[0003] However, existing manhole devices lack sufficient impact resistance in high-impact environments and cannot effectively protect internal components from damage, making them unsuitable for installation on horizontal explosive containers. Furthermore, existing manhole devices are not flexible enough to meet the need for rapid opening. Utility Model Content
[0004] The purpose of this invention is to provide a manhole device and an explosive container that have good impact resistance, are easy to operate, and can meet the need for rapid opening.

[0009] A manhole cover assembly includes a manhole cover and an opening / closing drive. The manhole cover has second wedges spaced apart on its edge. When the clamp rotates relative to the connecting flange, the clamp has at least a first position such that the gap between the second wedge and the first wedge corresponds, thereby allowing the manhole cover to enter or exit the manhole cover cavity under the action of the opening / closing drive. The clamp also has at least a second position such that the first wedge corresponds to the second wedge.
[0010] In an optional embodiment, the first wedge has a first inclined surface on the side near the connecting flange, and the second wedge has a second inclined surface on the side away from the connecting flange. When the manhole cover is located in the manhole cover cavity and the clamp is rotated to the second position, the first inclined surface and the second inclined surface are in contact.
[0011] In an optional embodiment, the clamp assembly further includes a rotation drive component, which includes a first drive component and a second drive component. The first drive component and the second drive component are respectively disposed on both sides of the clamp, and the first drive component and the second drive component have opposite driving directions to make the clamp rotate.
[0012] In an optional embodiment, the clamp includes a first part and a second part, one end of the first part and one end of the second part are fixedly connected by a first connector, the other end of the first part and the other end of the second part are fixedly connected by a second connector, the first connector is driven by the first driving member, and the second connector is driven by the second driving member.
[0013] In an optional embodiment, the first driving component includes a first mounting base and a first hydraulic cylinder, and the second driving component includes a second mounting base and a second hydraulic cylinder. The first mounting base and the second mounting base are respectively fixed on both sides of the clamp. One end of the first hydraulic cylinder is rotatably connected to the first mounting base, and the other end of the first hydraulic cylinder is rotatably connected to the first connecting member. One end of the second hydraulic cylinder is rotatably connected to the second mounting base, and the other end of the second hydraulic cylinder is rotatably connected to the second connecting member. The driving directions of the first hydraulic cylinder and the second hydraulic cylinder are opposite.
[0014] In an optional embodiment, a sealing ring is provided at the end of the connecting flange away from the manhole, the sealing ring being used to seal the connecting flange and the manhole cover.
[0015] In an optional embodiment, the opening and closing drive includes a fixed base, a rotating arm, and a third hydraulic cylinder. The fixed base is fixed to the side of the manhole, the rotating arm is rotatably connected to the fixed base, and the third hydraulic cylinder is used to drive the rotating arm to rotate relative to the fixed base. The end of the rotating arm away from the fixed base is fixedly connected to the manhole cover.
[0016] In an optional embodiment, the end of the rotating arm away from the fixed base is detachably connected to the manhole cover.
[0017] In an optional embodiment, a bearing is provided between the connecting flange and the clamp.
[0018] Secondly, this utility model provides an explosive container, including the manhole device described in any of the foregoing embodiments.
[0019] The beneficial effects of the manhole device and explosive container provided in this embodiment of the invention include:
[0020] This utility model relates to a manhole device comprising a connecting flange, a clamp assembly, and a manhole cover assembly. The connecting flange is fixedly positioned at the manhole location. The clamp assembly includes a clamp fitted onto the connecting flange. A first wedge is spaced at a distance from the edge of the clamp at the end furthest from the connecting flange. A manhole cover cavity is provided within the clamp. The clamp is rotatable relative to the axis of the connecting flange. The manhole cover assembly includes a manhole cover and an opening / closing drive component. A second wedge is spaced at a distance from the edge of the manhole cover. When the clamp rotates relative to the connecting flange, the clamp has at least a first position such that the gap between the second and first wedges corresponds, thereby allowing the manhole cover to enter or exit the manhole cover cavity under the action of the opening / closing drive component. The clamp also has at least a second position such that the first and second wedges correspond. By providing a first wedge on the clamp and a second wedge on the manhole cover, when the clamp rotates, the second wedge can selectively correspond to the first wedge or to the gap between the first wedges. When the gap between the second wedge and the first wedge aligns, the manhole cover can enter or exit the manhole cover cavity under the action of the opening and closing drive, thereby abutting or disengaging from the connecting flange, and thus closing or opening the manhole. When the second wedge is correspondingly set with the first wedge, when the manhole cover is engaged into the manhole cover cavity, the second wedge abuts against the first wedge, making it less likely for the manhole cover to fall off, thus improving the impact resistance of the manhole device. This invention has good impact resistance, is easy to operate, and can meet the need for rapid opening. Attached Figure Description

[0031] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0033] Please refer to Figures 1-3 This utility model provides an explosive container 1000, which is typically mounted on a mobile vehicle for use in specific industrial testing or experimental environments. The explosive container 1000 has a manhole 201 on its cylindrical body for the entry and exit of personnel, instruments, or materials.
[0034] Specifically, the explosive container 1000 includes a container body 200 and a manhole device 100. The container body 200 is provided with a manhole 201 for personnel, instruments or materials to enter or exit.
[0035] The manhole device 100 includes a connecting flange 10, a clamp assembly 20, and a manhole cover assembly 30. The connecting flange 10 is fixedly disposed at the position of the manhole 201. The clamp assembly 20 includes a clamp 21 fitted onto the connecting flange 10. A first wedge 215 is spaced apart at the edge of the end of the clamp 21 away from the connecting flange 10. A manhole cover cavity 216 is provided within the clamp 21. The clamp 21 is rotatable relative to the axis of the connecting flange 10. The manhole cover assembly 30 includes a manhole cover 31 and an opening / closing drive 32. A second wedge 311 is spaced apart at the edge of the manhole cover 31. The second wedge 311 may selectively correspond to the first wedge 215 or the gap between the first wedge 215. The opening / closing drive 32 is used to drive the manhole cover 31 into or out of the manhole cover cavity 216. Specifically, when the clamp 21 rotates relative to the connecting flange 10, the clamp 21 has at least a first position, such that the gap between the second wedge 311 and the first wedge 215 corresponds, thereby allowing the manhole cover 31 to enter or exit the manhole cover cavity 216 under the action of the opening and closing drive 32. The clamp 21 also has at least a second position, such that the first wedge 215 corresponds to the second wedge 311.
[0036] Understandably, when the clamp 21 rotates to the first position, and the gap between the second wedge 311 and the first wedge 215 corresponds, the second wedge 311 can move within the gap between the first wedge 215. The manhole cover 31 can enter or exit the manhole cover cavity 216 under the action of the opening / closing drive 32, thereby abutting or disengaging from the connecting flange 10, and thus closing or opening the manhole 201. When the second wedge 311 is correspondingly positioned with the first wedge 215, and the manhole cover 31 is engaged in the manhole cover cavity 216, the second wedge 311 abuts against the first wedge 215. The second wedge 311 is blocked by the first wedge 215, making it difficult for the manhole cover 31 to fall off, thus improving the impact resistance of the manhole device 100.
[0037] Please refer to Figure 3 and Figure 4 Specifically, in this embodiment, the clamp 21 is cylindrical. First wedges 215 are arranged in a circumferential array around the axis of the clamp 21, and are positioned on the inner wall of the end of the clamp 21 furthest from the connecting flange 10, forming a first annular tooth shape between the first wedges 215 and the inner wall of the clamp 21. The manhole cover 31 is disc-shaped, and second wedges 311 are positioned on the edge of the manhole cover 31 and arranged in a circumferential array around the center of the manhole cover 31, forming a second annular tooth shape between the second wedges 311 and the edge of the manhole cover 31. Specifically, the number of first wedges 215 is the same as the number of second wedges 311, so that the shapes of the first and second annular teeth correspond or are identical. Further, the outline of the first annular tooth shape should be slightly larger than the outline of the second annular tooth shape, so that the manhole cover 31 can smoothly enter the manhole cover cavity 216.
[0038] Please refer to Figure 4 Furthermore, the first wedge 215 has a first inclined surface 2151 on the side near the connecting flange 10. The second wedge 311 has a second inclined surface 3111 on the side away from the connecting flange 10. When the manhole cover 31 is located in the manhole cover cavity 216 and the clamp 21 is rotated to the second position, the first inclined surface 2151 and the second inclined surface 3111 are in contact. It can be understood that when the clamp 21 is in the first position, the second wedge 311 can move through the gap between the first wedges 215, allowing the manhole cover 31 to enter the manhole cover cavity 216. When the manhole cover 31 enters the manhole cover cavity 216 and abuts against the connecting flange 10, closing the manhole 201, rotating the clamp 21 causes the first wedge 215 and the second wedge 311 to move relative to each other, and then the first inclined surface 2151 and the second inclined surface 3111 move relative to each other. When the first inclined surface 2151 and the second inclined surface 3111 are fully in contact, the first wedge 215 and the second wedge 311 correspond to each other. By setting the first inclined surface 2151 and the second inclined surface 3111, it is possible to prevent the clamp 21 from rotating too much, that is, the first wedge 215 moves a tooth-shaped distance relative to the second wedge 311.
[0039] It is understandable that the first wedge 215 and the second wedge 311 correspond to each other as follows: in the direction along the axis of the clamp 21, the first wedge 215 and the second wedge 311 coincide.
[0040] Please refer to Figures 1-3 Furthermore, the clamp assembly 20 also includes a rotation drive 22. The rotation drive 22 includes a first drive 221 and a second drive 222. The first drive 221 and the second drive 222 are respectively disposed on both sides of the clamp 21. The first drive 221 and the second drive 222 drive in opposite directions to rotate the clamp 21.
[0041] It is understood that in this embodiment, the clamp 21 is cylindrical. By placing the first driving member 221 and the second driving member 222 on both sides of the clamp 21, and driving the first driving member 221 and the second driving member 222 respectively driving the upper and lower sides of the clamp 21 to move along their tangents, the clamp 21 is rotated.
[0042] To facilitate the rotation of the clamp 21, a bearing is provided between the connecting flange 10 and the clamp 21 in this embodiment.
[0043] Furthermore, to facilitate the installation of the clamp 21, the clamp 21 includes a first part 211 and a second part 212. One end of the first part 211 is fixedly connected to one end of the second part 212 via a first connector 213. The other end of the first part 211 is fixedly connected to the other end of the second part 212 via a second connector 214. The first connector 213 is drive-connected to the first driving member 221. The second connector 214 is drive-connected to the second driving member 222.
[0044] Specifically, in this embodiment, the clamp 21 is cylindrical. The first part 211 and the second part 212 are each half of the cylinder, so that when the first part 211 and the second part 212 are connected, the first connector 213 and the second connector 214 are located in the diametrical direction of the clamp 21.
[0045] In detail, the first driving component 221 includes a first mounting base 2211 and a first hydraulic cylinder 2212. The second driving component 222 includes a second mounting base 2221 and a second hydraulic cylinder 2222. The first mounting base 2211 and the second mounting base 2221 are respectively fixed on both sides of the clamp 21. Specifically, the first mounting base 2211 and the second mounting base 2221 are fixedly mounted on the container body 200. One end of the first hydraulic cylinder 2212 is rotatably connected to the first mounting base 2211. The other end of the first hydraulic cylinder 2212 is rotatably connected to the first connecting member 213. One end of the second hydraulic cylinder 2222 is rotatably connected to the second mounting base 2221. The other end of the second hydraulic cylinder 2222 is rotatably connected to the second connecting member 214. The driving directions of the first hydraulic cylinder 2212 and the second hydraulic cylinder 2222 are opposite.
[0046] It is understandable that the first driving component 221 and the second driving component 222 are symmetrical about the axis of the clamp 21.
[0047] Furthermore, a sealing ring 11 is provided at the end of the connecting flange 10 away from the manhole 201. The sealing ring 11 is used to seal the connecting flange 10 and the manhole cover 31.
[0048] Furthermore, the opening / closing drive component 32 includes a fixed base 322, a rotating arm 321, and a third hydraulic cylinder 323. The fixed base 322 is fixed to the side of the manhole 201. Specifically, the fixed base 322 is fixed to the container body 200. The rotating arm 321 is rotatably connected to the fixed base 322. The third hydraulic cylinder 323 is used to drive the rotating arm 321 to rotate relative to the fixed base 322. The end of the rotating arm 321 away from the fixed base 322 is fixedly connected to the manhole cover 31. It can be understood that the manhole cover 31 in this embodiment has a side-flipping structure, and the rotation of the rotating arm 321 causes the manhole cover 31 to enter or exit the manhole cover cavity 216.
[0049] In this embodiment, the end of the rotating arm 321 away from the fixed base 322 is detachably connected to the manhole cover 31. Specifically, the end of the rotating arm 321 away from the fixed base 322 is bolted to the manhole cover 31. It is understood that the detachable structure facilitates maintenance of the manhole cover assembly 30.
[0050] The beneficial effects of the manhole device 100 and the explosive container 1000 provided in this embodiment of the present invention include:
[0051] The manhole device 100 of this utility model includes a connecting flange 10, a clamp assembly 20, and a manhole cover assembly 30. The connecting flange 10 is fixedly disposed at the position of the manhole 201. The clamp assembly 20 includes a clamp 21 sleeved on the connecting flange 10. A first wedge 215 is spaced apart at the edge of the end of the clamp 21 away from the connecting flange 10. A manhole cover cavity 216 is provided inside the clamp 21. The clamp 21 is rotatable relative to the axis of the connecting flange 10. The manhole cover assembly 30 includes a manhole cover 31 and an opening / closing drive 32. A second wedge 311 is spaced apart at the edge of the manhole cover 31. When the clamp 21 rotates relative to the connecting flange 10, the clamp 21 has at least a first position, such that the gap between the second wedge 311 and the first wedge 215 corresponds, thereby allowing the manhole cover 31 to enter or exit the manhole cover cavity 216 under the action of the opening / closing drive 32. The clamp 21 has at least a second position, such that the first wedge 215 corresponds to the second wedge 311. By setting a first wedge 215 on the clamp 21 and a second wedge 311 on the manhole cover 31, when the clamp 21 rotates, the second wedge 311 can selectively correspond to the first wedge 215 or the gap between the first wedge 215. When the gap between the second wedge 311 and the first wedge 215 corresponds, the manhole cover 31 can enter or exit the manhole cover cavity 216 under the action of the opening and closing drive 32, thereby abutting or disengaging from the connecting flange 10, and thus closing or opening the manhole 201. When the second wedge 311 is correspondingly set with the first wedge 215, when the manhole cover 31 is engaged into the manhole cover cavity 216, the second wedge 311 abuts against the first wedge 215, making it less likely for the manhole cover 31 to fall off, thus improving the impact resistance of the manhole device 100. This utility model has good impact resistance, is easy to operate, and can meet the needs of rapid opening.
[0052] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
