Abstract
Description
Technical Field
[0001] The invention relates to the technical field of deep well protection, in particular to an automatically foldable deep well protection device. Background Art
[0002] Power plants, steel mills and other factories in heavy industrial fields often have deep wells, which are used to store large equipment or conduct high-risk industrial activities. In the related technology, it is usually necessary to set up a manhole cover structure to close the deep well to prevent pedestrians or vehicles from falling in; at the same time, due to the needs of industrial activities, deep wells often need to be kept open. At present, deep wells mainly use retractable manhole covers. The deep well is open when the manhole cover is open, and the deep well is closed when the manhole cover is closed. When the manhole cover is opened to be perpendicular to the well surface, the side of the deep well where the manhole cover is set can be protected, but it cannot form a complete protection for the periphery of the deep well, and some sides of the deep well are still in an open state. Therefore, when the deep well is in an open state for a long time, the open part poses a great safety hazard to passing pedestrians and vehicles.
[0003] In the related art, fixed guardrails are usually used to provide supplementary protection for deep wells in addition to manhole covers. However, the fixed guardrails still exist when the deep well is in a closed state, which limits the space utilization of the factory and is not conducive to the passage of pedestrians and vehicles. Summary of the invention

In the first state, the two cover plates are combined to close the deep well, and in the second state, each cover plate forms a protection for the deep well within its extension surface; the guardrail assembly includes two folding guardrails, two folding guardrails, and two folding guardrails. The guardrails are relatively arranged on the short sides, and each folding guardrail is rotatably connected to the two cover plates; the folding guardrail is suitable for folding or unfolding and is at least partially accommodated under the cover plate after folding; the driving assembly is arranged on the base and connected to the cover plate assembly to drive the cover plate to rotate relative to the base; wherein the two cover plates drive the two folding guardrails to unfold or fold synchronously when rotating relative to the base, so as to be suitable for the deep well protection device to switch between the unfolded state and the closed state; the deep well protection device forms a closed protection for the circumference of the deep well when in the unfolded state, and closes the wellhead of the deep well when in the closed state.

[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0040] Reference below Figure 1-Figure 14 An automatically foldable deep well protection device according to an embodiment of the present invention is described.
[0041] The present application proposes an automatically foldable deep well protection device, which includes a base 10, a cover assembly, a guardrail assembly and a drive assembly 40. The base 10 is arranged at the edge of the wellhead of the deep well, and the base 10 includes two long sides and two short sides; the cover assembly includes two cover plates 20, and the two cover plates 20 are flippably arranged on the long sides, and each cover plate 20 is suitable for rotating relative to the base 10 to switch between a first state and a second state. In the first state, the two cover plates 20 are combined to close the deep well, and in the second state, each cover plate 20 forms a protection for the deep well within its extension surface; the guardrail assembly includes two folding guardrails 30, two folding guardrails 30, The guardrails 30 are relatively arranged on the short sides, and each folding guardrail 30 is rotatably connected to the two cover plates 20; the folding guardrails 30 are suitable for folding or unfolding and are at least partially accommodated under the cover plates 20 after folding; the driving assembly 40 is arranged on the base 10 and is connected to the cover plate assembly to be suitable for driving the cover plates 20 to rotate relative to the base; wherein when the two cover plates 20 rotate relative to the base 10, the two folding guardrails 30 are driven to unfold or fold synchronously, so as to be suitable for the deep well protection device to switch between the unfolded state and the closed state; the deep well protection device forms a closed protection for the circumference of the deep well when in the unfolded state, and the deep well protection device closes the wellhead of the deep well when in the closed state.
[0042] According to the deep well protection device of the present application, the cover plate 20 can be flipped relative to the base 10, and when flipped to be close to the base 10, it is in the first state, such as Figure 2 , Figure 5 As shown, the two cover plates 20 are combined to cover the wellhead of the deep well to form a shield, thereby closing the deep well and preventing people or objects from falling; when they are flipped to be vertical or nearly vertical to the base 10, they are in the second state, as shown in FIG. Figure 3 , Figure 4 As shown, each cover plate 20 forms a protection for the deep well at its installation position and within the range of its extension surface, preventing people or objects from approaching the wellhead or entering by mistake. Furthermore, the folding guardrail 30 is arranged between two adjacent cover plates 20 and is rotatably connected to the sides of the two cover plates 20 respectively. The folding guardrail 30 and the cover plates 20 can form a continuous structure in the circumferential direction of the deep well; Figure 3 , Figure 4 As shown, when the foldable guardrail 30 is unfolded, continuous circumferential protection is provided to the deep well to avoid protection gaps that may cause people or objects to enter or even fall into the well by mistake; Figure 2 As shown, when the folding guardrail 30 is folded, the folding guardrail 30 is accommodated under the cover plate 20 and does not occupy the space above the cover plate 20. In addition, the driving component 40 controls the cover plate 20 to flip, and the cover plate 20 flips to drive the folding guardrail 30 to fold or unfold, thereby realizing the closing or unfolding of the entire deep well protection device, so that the deep well protection device of the present application has a high degree of automation, and can automatically realize folding or unfolding by controlling the operation of the driving component 40, thereby improving the construction efficiency.
[0043] According to the deep well protection device of the present application, since the cover plate 20 and the folding guardrail 30 form a continuous structure in the circumference of the deep well, when the deep well protection device is deployed, it can provide all-round protection for the circumference of the deep well to prevent people or objects from entering the wellhead area or even falling into the well; at the same time, since the folding guardrail 30 can be folded under the drive of the cover plate 20 when the deep well is closed, and after folding, it can be stored and at least partially placed under the cover plate 20, the deep well protection device of the present application can avoid occupying the space above the well when the deep well is closed, and avoid hindering the passage of people or objects; in addition, the folding guardrail 30 of the present application has a high degree of automation, which can effectively improve construction efficiency.
[0044] In the related art, deep wells are mostly constructed as rectangular deep wells. This application is mainly designed for rectangular deep wells, but can also be applied to deep wells of other shapes. In some embodiments, such as Figure 1 , Figure 6 As shown, the base 10 is arranged at the edge of the wellhead of the deep well, and its cross-section is constructed as a hollow rectangle, which surrounds the deep well. Specifically, the main part of the base 10 is buried underground, and part of it is exposed on the ground to facilitate the installation of the cover plate 20. Two cover plates 20 are symmetrically arranged on a set of opposite long sides of the base 10; two folding guardrails 30 are symmetrically arranged on a set of opposite short sides of the base 10. When the cover plate 20 is flipped toward the wellhead, the folding guardrail 30 is driven to fold toward the wellhead; when the cover plate 20 is flipped out of the well, the folding guardrail 30 is driven to unfold out of the well. In this embodiment, the cover plate 20 is constructed as a rectangle, and the folding guardrail 30 appears as a rectangle when unfolded.
[0045] According to some embodiments of the present application, the folding guardrail 30 includes a first folding unit 31 and a second folding unit 32. The first folding unit 31 is configured as two, and the two first folding units 31 are rotatably connected to the sides of the two cover plates 20 respectively; the second folding unit 32 is connected between the two first folding units 31 and is suitable for moving relative to the first folding unit 31; and the second folding unit 32 is configured as at least one. In this embodiment, by providing multiple folding units and utilizing the relative movement between the folding units to achieve the folding and unfolding of the folding guardrail 30, the structure is flexible and has good stability.
[0046] According to some embodiments of the present application, the first folding unit 31 is configured as a first folding plate 31, and the second folding unit 32 is configured as a second folding plate 32; when the folding guardrail 30 is folded, at least a portion of the two first folding plates 31 and the second folding plates 32 overlap in the vertical direction. In this embodiment, the first folding unit 31 and the second folding unit 32 are configured as a plate structure, which has higher safety and stability; and at least a portion of the two first folding plates 31 and the second folding plates 32 overlap in the vertical direction to match the position of the cover plate 20, so that the structure is compact and easy to be accommodated under the cover plate 20.
[0047] According to some embodiments of the present application, the first folding plate 31 and the second folding plate 32 are connected via a rotation axis, and the extension direction of the rotation axis forms an angle of 45° with the side of the cover plate 20 .
[0048] It should be noted that the side edge of the first folding plate 31 connected to the cover plate 20 needs to rotate 90° around the rotation center of the cover plate 20 during the folding process. In view of the two forms of the folding guardrail 30, the at least two folding lines of the folding guardrail 30 need to form a 45° angle with the side edges of the two cover plates 20. In this embodiment, the extension direction of the rotation axis of the first folding plate 31 and the second folding plate 32 forms a 45° angle with the side edge of the cover plate 20, so that the relative surfaces of the first folding plate 31 and the second folding plate 32 can fit after folding, without the need for structural deformation or other structural coordination. Therefore, the second folding plate 32 is constructed as one to meet the folding conditions, thereby simplifying the structure of the folding guardrail 30.
[0049] According to some embodiments of the present application, the extension direction of the rotation axis passes through the rotation center of the cover plate 20, and the first folding unit 31 and the second folding unit 32 are suitable for relative rotation around the rotation axis. Figure 7-9 As shown, the first folding unit 31 and the second folding unit 32 only need to rotate relative to each other to realize the deformation of the folding guardrail 30 and coordinate with the movement of the cover plate 20. A rotating pair is formed between the structures, which can increase the system stiffness of the folding guardrail 30 and improve the stability of the folding guardrail 30 during the deformation process.
[0050] In some embodiments, Figure 7 , 8 As shown, the first folding plate 31 is constructed as an isosceles right triangle, and the sides of the first folding plate 31 connected to the cover plate 20 are of equal length, and the second folding plate 32 is constructed as an isosceles right triangle, and the hypotenuse of the first folding plate 31 is of equal length to the side of the second folding plate 32, and the area of the second folding plate 32 is twice the area of the first folding plate 31. When the folding guardrail 30 is folded, the first folding plate 31 and half of the second folding plate 32 can completely overlap. The folding guardrail of this embodiment has a simple structure and high stability.
[0051] In some embodiments, Fig. 9As shown, the first folding plate 31 is constructed as an isosceles right triangle, and the side of the first folding plate 31 connected to the cover plate 20 is shorter than the side of the cover plate 20. At this time, the bottom side of the second folding plate 32 is greater than twice the length of the side of the first folding plate 31. The second folding plate 32 can be constructed as an isosceles trapezoid or other structure with a bottom angle of 45°. When the folding guardrail 30 is folded, the first folding plate 31 partially overlaps with the second folding plate 32, and the cover plate 20 partially overlaps with the second folding plate 32. In this embodiment, when the deep well protection device is unfolded, the height of the folding guardrail 30 is lower than the height of the cover plate 20, but it can meet the protection requirements. The folding guardrail 30 of this embodiment can reduce costs and is more suitable for deep well protection of a larger area.
[0052] It should be noted that the shape of the first folding plate 31 is not limited to the above-mentioned isosceles right triangle, and can also be constructed into other shapes, and the shape of the second folding plate 32 matches therewith.
[0053] According to some embodiments of the present application, the center line of the rotation axis is located above the rotation center of the cover plate 20, and the first folding unit 31 and the second folding unit 32 are adapted to rotate relative to each other around the rotation axis and move relative to each other along the extension direction of the rotation axis. Fig.10 As shown, a cylindrical pair is formed between the first folding unit 31 and the second folding unit 32, which can rotate and slide relative to each other, so that the folding guardrail 30 has higher flexibility, can reduce structural interference, and is convenient for switching between the folded state and the unfolded state. At the same time, during the folding process of the folding guardrail 30, the second folding unit 32 rotates relative to the first folding unit 31 and moves relative to the base 10 toward the outside of the well, which can better cover the gap on the short side of the base 10 and improve the shielding effect of the deep well protection device.
[0054] According to some embodiments of the present application, the deep well protection device further comprises a locking assembly 50, which is disposed on the folding guardrail 30 and is adapted to selectively restrict the relative movement of the first folding unit 31 and the second folding unit 32 or release the restriction. In this embodiment, by disposing the locking assembly 50 to selectively restrict the first folding unit 31 and the second folding unit 32, restricting their relative rotation and / or relative sliding, the stability of the folding guardrail 30 can be enhanced, and its ability to cope with the influence of external forces such as wind is improved, so as to better play a protective role.
[0055] In some embodiments, Figure 7As shown, the locking assembly 50 includes a first locking portion 51 and a second locking portion 52. The first locking portion 51 can be configured as a positioning pin, and the second locking portion 52 can be configured as a positioning hole. In the first folding unit 31 and the second folding unit 32, one is provided with a positioning pin, and the other is provided with a positioning hole. After the deep well protection device is unfolded, the positioning pin is inserted into the positioning hole to limit the first folding unit 31 and the second folding unit 32, so that the relative positions remain unchanged. Furthermore, the positioning pin can be configured as an electromagnetic pin, which can improve the control efficiency, simplify the control process, and help improve the automation of the device.
[0056] In the above embodiment, the first locking portion 51 may be disposed at the top of the second folding unit 32 , and the second locking portion 52 may be correspondingly disposed at the bottom corner of the first folding unit 31 for easy manual operation or observation.
[0057] According to some embodiments of the present application, the first folding unit 31 and the second folding unit 32 are both formed with a first connecting portion 33 and connected to the rotating shaft through the first connecting portion 33 to achieve a rotatable connection. Further, the first connecting portion 33 protrudes from the surface of the first folding unit 31 and the second folding unit 32, and the first folding unit 31 and the second folding unit 32 are both formed with a first avoidance groove 34 that cooperates with the first connecting portion 33. Figure 7 As shown, in this embodiment, the first folding unit 31 and the second folding unit 32 are connected by the first connecting portion 33. The first connecting portion 33 is configured to protrude from the surfaces of the first folding unit 31 and the second folding unit 32, which are the surfaces facing each other after folding, so that when the angle between the first folding unit 31 and the second folding unit 32 is reduced, the structures can be prevented from interfering with each other, so that the surfaces facing each other can be close to or even attached to each other after the first folding unit 31 and the second folding unit 32 are relatively rotated, so that the structures are compact, the coordination between the structures is facilitated, the space is saved, and the storage is convenient.
[0058] Furthermore, if Fig.11 , 12 As shown, the side where the first folding unit 31 is connected to the cover plate 20 is also provided with a first connecting portion 33, and the cover plate 20 is formed with a second connecting portion 22 and a second avoidance groove 23. The first folding unit 31 is rotatably connected to the second connecting portion 22 of the cover plate 20 through the first connecting portion 33, and the second avoidance groove 23 cooperates with the first connecting portion 33.
[0059] According to some embodiments of the present application, the deep well protection device further includes a support frame 70, which is disposed on the short side of the base, and the support frame 70 is formed with at least one bearing surface 71 for supporting the cover plate 20. In this embodiment, the support frame 70 can be provided to improve the bearing capacity and stability of the deep well protection device in the folded state, and at the same time, the rotation angle of the cover plate 20 relative to the base 10 can be controllable, and the relative position of the cover plate 20 in the first state can be changed by changing the size and shape of the support frame 70.
[0060] It should be noted that when the two cover plates 20 are located in the same plane and abut against each other in the first state, the structure may be in a singular position and the relative movement between the structures may be restricted, making it difficult or impossible for the cover plates 20 to generate relative movement and unable to switch from the first state to the second state, causing the deep well to be unable to be opened.
[0061] In view of the above problems, according to some embodiments of the present application, the support frame 70 is higher than the rotation center of the cover plate 20, and the supporting surface 71 is inclined toward the rotation center of the cover plate 20. Figure 4 , 5 As shown, due to the limiting effect of the support frame 70, when the cover plate 20 is rotated to the first state, there is a small angle between the cover plate 20 and the base 10, so that the two cover plates 20 cannot be moved to the same plane, thereby avoiding the generation of singular points and the problem of deep wells being difficult to open; at the same time, the supporting surface 71 is inclined to fit the cover plate 20 in the first state as closely as possible, thereby providing a more stable supporting force for the cover plate 20.
[0062] Specifically, Figure 6 As shown, the support frame 70 is constructed in two pieces, which are respectively arranged at the center of the two short sides of the base 10, that is, correspondingly arranged in the middle of the two cover plates 20. Two supporting surfaces 71 are formed on the top of the support frame 70, and the two supporting surfaces 71 are respectively inclined toward the rotation center of the two cover plates 20 to support the two cover plates 20.
[0063] According to some embodiments of the present application, a plurality of weight-reducing holes are formed on the cover plate 20 and / or the folding guardrail 30. In this embodiment, the weight-reducing holes are provided to reduce the mass of the structure, thereby reducing the control burden, facilitating the control process, and reducing the structural cost while meeting the protection requirements.
[0064] According to some embodiments of the present application, the deep well protection device further includes a bearing seat 60, which is disposed on the base 10; the cover plate 20 is formed with a mounting portion 21, which is rotatably connected to the bearing seat 60. Figure 1 , Figure 6As shown, the cover plate 20 is installed on the base 10 through the bearing seats 60. Specifically, mounting portions 21 are respectively formed at the bottom of both sides of the cover plate 20, which are rotatably connected to the two bearing seats 60 to enable the cover plate 20 to be flipped and set on the base 10.
[0065] Further, the driving assembly 40 can be arranged near the bearing seat 60, and its output end is connected to the mounting portion 21 and is suitable for driving the mounting portion 21 to rotate and then drive the cover plate 20 to rotate relative to the base 10. The driving assembly 40 is diverse and can be flexibly selected and arranged according to control requirements.
[0066] In some embodiments, the driving assembly 40 includes: a driving member 41, a first driving rod 42, and a second driving rod 43. The driving member 41 is disposed on the base 10; one end of the first driving rod 42 is connected to the output shaft of the driving member 41, and the driving member 41 is suitable for driving the first driving rod 42 to rotate; one end of the second driving rod 43 is rotatably connected to the cover plate 20, and the other end of the second driving rod 43 is rotatably connected to the other end of the first driving rod 42. Fig.10 , Fig.11 As shown, this embodiment realizes the rotational motion transmission through the combination of the first drive rod 42 and the second drive rod 43, and the structure is simple, the transmission effect is stable, and the structure is highly flexible. Further, when the center lines of the first drive rod 42 and the second drive rod 43 are parallel, the drive assembly 40 is located at the dead point position, and the bearing capacity and stability of the structure are relatively high; therefore, in some embodiments, when the cover plate 20 is in the second state, the first drive rod 42 and the second drive rod 43 are parallel, thereby providing reliable support and fixation for the cover plate 20, so that it can play a stable protective role. In order to facilitate the connection between the second drive rod 43 and the cover plate 20, the drive assembly 40 also includes a connecting seat 44, one side of the connecting seat 44 is fixedly connected to the cover plate 20, and the other side is hinged to the second drive rod 43.
[0067] The driving assembly 40 is structured in two parts, which are respectively arranged on the inner walls opposite to the long sides of the base 10 and control the rotation of the cover plate 20 opposite thereto.
