Technical Field

[0001] The utility model relates to the technical field of manhole cover monitoring, in particular to an adjustable manhole cover sensor mounting base. Background Art

[0002] Road manhole covers are related to the convenience of the city. Their huge number makes management extremely difficult. Manhole covers often have problems such as sinking, tilting, illegal opening, theft and loss, which are often difficult to discover and solve through manual inspections. Therefore, with the development of intelligent monitoring technology, it has become a trend to install manhole cover monitors on manhole covers for intelligent monitoring of manhole covers. However, since the monitoring instrument monitors the manhole cover, it is often necessary to install the monitor at the bottom of the manhole cover, which requires professional construction personnel to install it. In addition, it is necessary to drill holes on the lower end of the manhole cover, and fix the base of the monitoring mechanism to the lower end of the manhole cover with bolts, or directly fix the monitoring mechanism under the manhole cover. The installation and fixation is very troublesome.

[0003] To this end, we designed an adjustable manhole cover sensor mounting base to solve the above problems. Utility Model Content

[0004] The utility model provides an adjustable manhole cover sensor mounting base to adapt to the shapes of different manhole cover backs and facilitate the installation of intelligent manhole cover sensors. The base can be rotated and adapted according to the shape and width of the cross beam (rib) on the back of the manhole cover. The installation is simple and convenient, meeting the actual engineering application of the manhole cover sensor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An adjustable manhole cover sensor mounting base comprises a mounting base and a clamp. The mounting base for mounting the manhole cover sensor is fixedly mounted on one end face of the clamp via a fixing member. A locking bolt is threadedly connected to one side wall of the clamp.

[0009] As a further preferred embodiment of the present invention, the cross-sectional structure of the extrusion end is conical, and the area of ​​the extrusion surface is larger than the area of ​​the connection interface with the threaded rod body.

[0010] As a further preferred embodiment of the present invention, the mounting base is a circular or quadrilateral plate-like structure, a sensor mounting hole for mounting the manhole cover sensor is provided on the mounting base, and the fixing piece is a cylindrical threaded fastener equipped with a nut.

[0011] As a further preferred embodiment of the present invention, the manhole cover sensor is installed on the upper end surface of the mounting base through a sensor mounting hole.

[0012] As a further preferred embodiment of the present invention, the sensor mounting hole is installed with an equipment cabin through the fixing member, the equipment cabin is a cavity sealing structure with a rectangular interior, and the manhole cover sensor is installed and fixed in the equipment cabin.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model fixes the mounting base on the lower ribs of the manhole cover through a clamp, and then installs the manhole cover monitoring sensor on the base. No professional construction personnel are required to operate, and the installation can be achieved by utilizing the inherent structure of the manhole cover itself. The installation operation is simple, and will not cause damage to the manhole cover structure, nor will it reduce the structural strength of the manhole cover. By adjusting the gap between the locking bolt and the clamp, and being able to rotate the clamp to any angle and then clamp it on the ribs on the back of the manhole cover, it is adaptable to manhole cover ribs of different sizes and directions, thereby expanding the scope of application of the mounting base and the actual engineering application scenarios of the manhole cover sensor.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1 and Figure 4 As shown, in this embodiment, an adjustable manhole cover sensor mounting base is proposed, and its structure mainly includes a mounting base 1 and a clamp 2. Among them, the mounting base 1 for mounting the manhole cover sensor 6 is fixedly mounted on one end surface of the clamp 2 through a fixing member 11, and a locking bolt 3 is threadedly connected on one side wall of the clamp 2, and one end of the locking bolt 3 and the inner side wall of the other side of the clamp 2 are clamped on the rib 41 on the lower surface of the manhole cover 4, and the number of the clamps 2 is at least two groups.

[0022] It is worth mentioning that, referring to Figures 1 to 3 As an important component connected and fixed to the manhole cover 4, in order to adapt to the installation of various manhole cover 4 structures, the cross-section of the clamp 2 is preferably set to a U-shaped structure in this embodiment to facilitate clamping the ribs 41 at the bottom of the manhole cover 4.

[0023] For the installation connection between the locking bolt 3 and the clamp 2, in this embodiment, a threaded hole 21 for threaded connection of the locking bolt 3 is opened on any side surface of the clamp 2, and a through hole 22 for the fixing member 11 to pass through is opened on the lower end surface of the clamp 2.

[0024] The locking bolt 3 includes a threaded rod body 31, an extrusion end 32 and a locking end 33. The extrusion end 32 and the locking end 33 are respectively arranged at the two ends of the threaded rod body 31, and the locking end 33 is fixedly arranged at the end of the threaded rod body 31, and the extrusion end 32 is threadedly installed at the end of the threaded rod body 31. The threaded rod body 31 passes through the side wall of the clamp 2, and the extrusion end 32 is located in the clamp 2. By screwing the locking end 33 with a practical wrench tool, the threaded rod body 31 is rotated, and the end face of the extrusion end 32 is driven to move toward the side wall of the clamp 2, so that the extrusion end 32 and the side wall of the clamp 2 are tightly clamped on the rib 41 at the lower part of the manhole cover 4, so that the clamp 2 is fixed to the lower surface of the manhole cover 4 without damaging the structure of the manhole cover 4.

[0025] In order to better generate the extrusion force on the rib 41 and increase the contact area between the extrusion end 32 and the rib 41 , the cross-sectional structure of the extrusion end 32 is designed as a conical structure in this embodiment, that is, the extrusion surface area of ​​the extrusion end 32 is larger than the area of ​​the connection interface connected to the threaded rod body 31 .

[0026] It should be noted that the mounting base 1 shown in the drawings of the specification is a circular ring structure, but the structure of the mounting base 1 is not limited to a circular ring plate structure, and a quadrilateral plate structure or other polygonal plate structure may also be adopted. A suitable structure may be selected according to the installation space under the manhole cover 4.

[0027] A sensor mounting hole 12 for mounting the manhole cover sensor 6 is provided on the mounting base 1, and the fixing member 11 is a cylindrical threaded fastener equipped with a nut. The first mounting method of the manhole cover sensor 6: the manhole cover sensor 6 is mounted on the upper end surface of the mounting base 1 (such as Figure 4 as shown).

[0028] Since the lower part of the manhole cover 4 is mostly dark and humid, water may accumulate under the manhole cover 4 during the rainy season in summer, which will have many adverse effects on the safe operation of the manhole cover sensor 6. Therefore, when considering the installation of the manhole cover sensor 6, the sealing of the installation environment of the manhole cover sensor 6 also needs to be considered. Figure 5 As shown, the second installation method of the manhole cover sensor 6: in this embodiment, the sensor mounting hole 12 is installed with the equipment cabin 5 through the fixing part 11, and the contact surface between the fixing part 11 and the equipment cabin 5 is provided with a sealing gasket. The equipment cabin 5 is a cavity sealing structure with a rectangular interior, and the manhole cover sensor 6 is installed and fixed in the equipment cabin 5.

[0029] It should be noted that the locking bolt 3 shown in the accompanying drawings is located directly between the two clamps 2, but this installation method is not the only one. The locking bolt 3 can also be set on the outside of the two clamps 2 and installed relative to each other. This installation method can expand the space of the mounting base 1 between the clamps 2, thereby expanding the installation space of the manhole cover sensor 6, which needs to be determined based on the equipment structure size of the manhole cover sensor 6.

[0030] When the utility model is used, the manhole cover sensor 6 is installed on the mounting base 1 by selecting the first or second mounting method according to the space environment under the manhole cover 4, and the clamping direction of the clamp 2 is adjusted according to the position and direction of the rib 41 at the bottom of the manhole cover 4, so as to ensure that the clamp 2 can clamp the rib 41 in the subsequent steps. Then the locking bolt 3 is inserted into the threaded hole 21 on one side of the clamp 2, the extrusion end 32 is threadedly installed on the end of the locking bolt 3, and the locking end 33 is rotated to move the extrusion surface of the extrusion end 32 toward the rib 41 at the bottom of the manhole cover 4, until the extrusion end 32 and the inner wall of the clamp 2 are firmly fixed on the rib 41, and finally the fixing member 11 passes through the through hole 22, and the fixing member 11 of the mounting base 1 is installed on the clamp 2.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
