Description

Technical Field

[0001] The utility model relates to the technical field of road facilities, in particular to an inspection well cover suitable for special-shaped curbstones and an installation structure thereof. Background Art

[0002] In order to create a beautiful landscape effect, special-shaped granite curbstones are usually used on both sides of the roads in many industrial parks and parks. They look natural and generous. However, since special-shaped granite curbstones are relatively heavy and each piece is constructed in a close-fitting manner, the rainwater inspection wells on both sides of the curbstones are extremely inconvenient for daily inspection and dredging after road construction. Especially for places with a large number of green plants, fallen leaves are easily deposited in the inspection wells, causing blockage of the pipe network. When extreme weather occurs, the ground rainwater cannot be discharged smoothly, which will cause flooding to the road surface and surrounding environment, causing certain losses to pedestrians, vehicles, park equipment, etc. Summary of the invention

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide an inspection well cover suitable for special-shaped curbstones and an installation structure thereof, the cover being able to maintain a consistent appearance with the special-shaped curbstone and being able to more intuitively reflect whether the inspection well is blocked without opening the cover.

[0004] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0005] On the one hand, the utility model provides an inspection well cover suitable for special-shaped curbstones, comprising a base, a well cover panel and a blockage warning mechanism;

[0006] The base comprises a frame body for erecting above the inspection well, the well cover panel is obliquely installed on the base, and its two ends can be crimped to the two ends of the base respectively;

[0007] The blockage warning mechanism includes an airbag, a warning member and a connecting rod. The manhole cover panel is provided with a drainage hole through which the warning member can pass. The connecting rod passes through the frame body of the base, and its two ends are respectively connected to the airbag and the warning member. The connecting rod is provided with a first limiter and a second limiter located on the upper and lower sides of the base respectively.

[0008] When the first limiting member contacts the upper portion of the base, the warning member is located below the manhole cover panel;

[0009] When the second limiting member contacts the lower portion of the base, the warning member is located in the drainage hole, or extends from the drainage hole to the outside of the manhole cover panel.

[0010] The utility model utilizes the buoyancy principle, and provides a blockage warning mechanism with an air bag, and provides a drainage hole on the special-shaped manhole cover panel for the warning member to pass through, so that when there is rainwater in the manhole, the air bag will move upward with the rise of the water level, thereby driving the warning member to move to the drainage hole or expose the drainage hole, making it convenient for inspectors to see the situation in the inspection manhole more clearly.

[0011] Optionally, the frame body of the base includes a bottom frame and a side frame vertically connected to each other, and the bottom frame is used to be horizontally erected above the inspection well;

[0012] The cross section of the manhole cover panel is the same arc or S-shape as the curbstones on both sides, one end of which is crimped to the top of the side frame, and the other end is crimped to the end of the bottom frame away from the side frame. The design of the base can adapt to the installation environment of the special-shaped curbstone on the one hand, and provide structural support for the special-shaped manhole cover panel on the other hand. When it is necessary to further check the blockage of the inspection well, it is only necessary to move or flip the upper manhole cover panel, which greatly reduces the workload and difficulty of maintenance personnel.

[0013] Optionally, the frame body of the base further includes inclined support columns whose two ends are respectively fixedly connected to the bottom frame and the side frame and form a triangle between the three;

[0014] And / or, one end of the manhole cover panel is hinged to the end of the bottom frame on the same side.

[0015] In order to realize the installation of the blockage warning mechanism on the base, optionally, a positioning plate is provided on the bottom frame of the base, the connecting rod passes through the positioning plate, and the first limiting member and the second limiting member are respectively arranged on the upper and lower sides of the positioning plate.

[0016] Optionally, hollow square tubes are provided at both ends of the manhole cover panel crimped to the base, and curved stainless steel shells are connected between the upper surfaces of the two hollow square tubes and between the lower surfaces of the two hollow square tubes; reinforcing ribs are provided between the two curved stainless steel shells. The reinforcing ribs are preferably hollow curved stainless steel tubes, which have a square cross-section and a curved shape that matches the curved shape of the manhole cover panel, extending from the pavement end to the curb end of the manhole cover panel. Similarly, the hollow square tubes used as the skeleton of the manhole cover panel are also made of stainless steel tubes, which can ensure the structural strength of the manhole cover panel, and the overall weight is lighter than that of a conventional solid manhole cover, making it easier to move.

[0017] Optionally, the warning member is a stainless steel plate arranged obliquely, and its oblique direction is adapted to the length extension direction of the drain hole. This design can ensure that the warning member has a more obvious warning effect in any situation.

[0018] Optionally, the upper surface of the manhole cover panel is provided with a stone color transfer layer having the same appearance as the curbstones on both sides, so that the appearance of the manhole cover panel is more consistent with the appearance of the curbstones on both sides;

[0019] And / or, the outer surface of the warning piece is provided with a colored coating. The outer surface of the warning piece can be set to red or other obvious colors, which has a better warning effect.

[0020] In a second aspect, the utility model provides an installation structure of the manhole cover of the first aspect, specifically, the manhole cover is arranged across the manhole, and the base and the manhole cover panel both have a first end facing the road surface and a second end facing the roadside green belt;

[0021] The airbag is located in the inspection well, and when the lower end of the airbag is flush with the top of the rainwater branch pipe in the inspection well, the warning member is located in or close to the drainage hole, and there is a distance margin between the second limiter and the base; when the lower end of the airbag is at a preset warning height, the second limiter abuts against the lower part of the base, and the warning member extends out of the drainage hole;

[0022] Wherein, the warning height is higher than the top of the rainwater branch pipe in the inspection well.

[0023] The above-mentioned installation structure can achieve that when there is a lot of water in the inspection well, the airbag drives the warning piece to rise to the drainage hole or close to the drainage hole, so that the maintenance personnel can know that there is a lot of water in the inspection well when they are close to the manhole cover. Only when there is a blockage in the inspection well, the warning piece will be exposed outside the manhole cover, so that the maintenance personnel can know the abnormal state of the current inspection well even if they are not close to the manhole cover, and deal with the blockage in time. And when a blockage occurs, the road maintenance personnel can easily open or flip up the upper manhole cover panel, and then clean, dredge and repair the rainwater well or rainwater pipe, which greatly reduces the risk of blockage of the drainage pipe.

[0024] Optionally, an isolation plate for isolating a roadside green belt is provided on the outer side surface of the second end of the base. The isolation plate can be made of a stainless steel plate, which can extend the service life of the entire manhole cover.

[0025] Optionally, the frame body of the base includes a bottom frame and a side frame vertically connected to each other, and the bottom frame is used to be horizontally erected above the inspection well;

[0026] The two ends of the bottom frame of the base are fixed to the ground around the inspection well by expansion bolts, so that the base is not easily displaced;

[0027] A galvanized angle iron is arranged outside the right-angled edge connecting the bottom frame and the side frame, so as to further isolate the base from the sediment corrosion of the roadside green belt.

[0028] Compared with the prior art, the utility model has the following advantages and progress:

[0029] (1) By utilizing the buoyancy of the water in the inspection well on the airbag and coordinating with the setting of the limit structure, a warning function can be realized when the water level in the inspection well is high, so that it can be visually seen whether there is a blockage in the inspection well without opening the well cover;

[0030] (2) The manhole cover as a whole is adapted to the shape of the special-shaped curbstones on both sides to set the base and manhole cover panel, which has better appearance consistency during application and can ensure the stability of the manhole cover structure;

[0031] (3) The split manhole cover panel and base design allows the manhole cover panel to be easily opened for cleaning, unblocking and repair when the inspection well is blocked, which improves the efficiency of solving the problem of inspection well blockage and the convenience of unblocking operations by maintenance personnel.

[0041] Example 1

[0042] Combination Figure 1-5 This embodiment introduces a manhole cover suitable for special-shaped curbstones, which includes a base 2, a manhole cover panel 1 and a blockage warning mechanism; the base 2 includes a frame body for erecting above the manhole, the manhole cover panel 1 is obliquely installed on the base 2, and its two ends are respectively pressed against the base 2;

[0043] The blockage warning mechanism includes an airbag 6, a warning member 7 and a connecting rod 5. The manhole cover panel 1 is provided with a drainage hole 17 through which the warning member 7 can pass; the connecting rod 5 passes through the frame body of the base 2, and its two ends are respectively connected to the airbag 6 and the warning member 7. The connecting rod 5 is provided with a limiting mechanism 8 located on the upper and lower sides of the base, namely a first limiting member 81 and a second limiting member 82;

[0044] When the first limiting member 81 contacts the upper portion of the base 2, the warning member 7 is located below the manhole cover panel 1;

[0045] When the second limiting member 82 contacts the lower portion of the base 2 , the warning member 7 is located in the drainage hole 17 , or extends from the drainage hole 17 to the outside of the manhole cover panel 1 .

[0046] When this embodiment is used, the curved surface shape of the manhole cover panel can be designed according to the shape of the curbstones on both sides, such as an arc, wave or other special-shaped curved surface, so as to maintain a consistent appearance after being connected with the curbstones on both sides. Regarding the connection method between the manhole cover panel and the base, a two-part free detachable connection can be used in a closed park, and a hinge can be used for connection in open parks, squares and other areas.

[0047] When there is rainwater in the well, the airbag will move upward as the water level rises, thereby driving the warning piece to move to the drainage hole or expose the drainage hole; it is convenient for inspectors to distinguish the water level in the well from the position of the warning piece, so as to understand the situation in the inspection well more intuitively and conveniently.

[0048] Example 2

[0049] Based on Example 1, this embodiment also has the following designs:

[0050] The frame body of the base 2 includes a bottom frame and a side frame 11 which are vertically connected to each other, and an inclined support column 16 which is fixedly connected to the bottom frame and the side frame at both ends and forms a triangle between the three. The bottom frame is used to be horizontally erected above the inspection well, and the base as a whole provides structural support for the special-shaped manhole cover panel.

[0051] The cross section of the manhole cover panel 1 is the same arc or S-shape as the curbstones on both sides, so as to adapt to the installation environment of the special-shaped curbstones. One end of the manhole cover panel 1 is crimped to the top of the side frame, and the other end is crimped to the end of the bottom frame away from the side frame, or at the same time, one end of the manhole cover panel is hinged to the top of the bottom frame or the side frame. When further inspection or treatment of the well blockage is required, only the upper manhole cover panel needs to be moved or turned over, which greatly reduces the workload and difficulty of maintenance personnel.

[0052] refer to Figure 1 In this embodiment, hollow stainless steel square tubes are respectively provided at both ends of the manhole cover panel 1 crimped to the base 2, and curved stainless steel shells are respectively connected between the upper surfaces of the two hollow square tubes and between the lower surfaces of the two hollow square tubes; reinforcing ribs 12 are provided between the two curved stainless steel shells. The reinforcing ribs are preferably hollow curved stainless steel tubes with a square cross-section. The curved shape matches the curved shape of the manhole cover panel, extending from the pavement end to the curb end of the manhole cover panel. Similarly, the hollow square tubes used as the skeleton of the manhole cover panel are also made of stainless steel tubes, which can ensure the structural strength of the manhole cover panel, and the overall weight is lighter than that of a conventional solid manhole cover, making it easier to move. A stainless steel frame 15 is provided on the outer surface of the end of the manhole cover panel facing the green belt.

[0053] refer to Figure 2As shown, the installation method of the blockage warning mechanism on the base is that the bottom frame of the base includes or is additionally provided with two square tubes 4, a positioning plate 3 is provided on the square tube, the connecting rod 5 passes through the positioning plate 3, and the first limit member 81 and the second limit member 82 are respectively provided on the upper and lower sides of the positioning plate 3.

[0054] The warning member 7 is a stainless steel plate arranged obliquely, and its oblique direction is adapted to the length extension direction of the drain hole 17. This design can ensure that the warning member has a relatively obvious warning effect in any situation. The outer surface of the warning member is provided with a color coating to enhance the warning effect.

[0055] The upper surface of the manhole cover panel 1 is provided with a stone color transfer layer that is the same as the appearance of the curbstones on both sides, so that the appearance of the manhole cover panel is more consistent with the appearance of the curbstones on both sides.

[0056] like Figure 1 As shown, in this embodiment, the design of the blockage warning device allows inspectors to more conveniently see the blockage situation in the well directly through the position of the warning piece, which is specifically reflected in:

[0057] When there is no water or the water level is low in the well, the first limiter is limited by the positioning plate, the airbag is located at the lowest position in the well, and the warning member is also located at the lowest position allowed below the drainage hole. The inspector can hardly see the warning member and can directly know that there is no abnormality in the well;

[0058] When there is water accumulation in the well, the airbag 6 floats up with the water surface, driving the warning member 7 to float up to the drainage hole, or even extend out of the well cover panel, so that personnel can visually find abnormalities in the inspection well.

[0059] Furthermore, when an abnormality occurs, the inspection manhole cover of this embodiment allows road maintenance personnel to easily open or flip up the upper manhole cover panel, so that they can clean, dredge and repair the rainwater well and rainwater pipes, thereby greatly reducing the risk of blockage in the drainage pipes and greatly reducing the workload.

[0060] Example 3

[0061] This embodiment introduces an installation structure of the inspection well cover described in embodiment 1 or 2. For details, refer to Figure 1 The manhole cover is arranged across the manhole, and the base and the manhole cover panel both have a first end facing the road surface and a second end facing the roadside green belt;

[0062] The airbag is located in the inspection well, and when the lower end of the airbag is flush with the top of the rainwater branch pipe in the inspection well, the warning member is located in or close to the drainage hole, and there is a distance margin between the second limiter and the base; when the lower end of the airbag is at a preset warning height, the second limiter abuts against the lower part of the base, and the warning member extends out of the drainage hole;

[0063] Wherein, the warning height is higher than the top of the rainwater branch pipe in the inspection well.

[0064] In actual application of the above-mentioned installation structure, when there is a lot of water in the inspection well, the airbag drives the warning piece to rise to the drain hole or close to the drain hole. When a blockage occurs only in the inspection well, the warning piece will be exposed outside the well cover, so that maintenance personnel can know the current abnormal state of the inspection well even if they are not close to the well cover, and deal with the blockage in time. When a blockage occurs, the road maintenance personnel can easily open or flip up the upper well cover panel to clean, dredge and repair the rainwater well or rainwater pipe, greatly reducing the risk of blockage of the drainage pipe.

[0065] In this embodiment, a stainless steel isolation plate for isolating the roadside green belt is provided on the outer side of the second end of the base, which can extend the service life of the manhole cover as a whole. A galvanized angle iron is provided on the right-angled side where the bottom frame and the side frame are connected, which is used to further isolate the base from the sand corrosion of the roadside green belt. The two ends of the bottom frame of the base are respectively fixed to the ground around the inspection well by expansion bolts, so that the base is not easily displaced.

[0066] In summary, refer to Figure 5 As shown, the manhole cover of the utility model is developed with the goal of solving the problem of inconvenient maintenance of special-shaped curbstone manholes in the park. It has been implemented internally and has achieved the above-mentioned effects, and can be applied to the same type of special-shaped curbstone manholes. The utility model is an application made to protect the corresponding technical solution.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
