It is mainly used for the measurement of static and dynamic deflection of bridges, acceptance and appraisal of bridge completion; inspection of special bridges such as military floating bridges and suspension bridges; deformation and vibration displacement monitoring of dams and docks; or deformation and vibration displacement of beams, columns, high-rise buildings, lifting machinery, drilling platforms, etc. of large-span structures;
[0003] The deflection instrument has a lens for observation, but most of the existing deflection instrument lenses are usually directly exposed to the outside world. At this time, dust and impurities in the air can easily adhere to the lens, causing inaccurate observation data due to lens contamination. Therefore, the lens needs to be cleaned manually at regular intervals. This method not only increases labor intensity, but also the strength of manual cleaning is difficult to control, which may cause lens damage. In view of this, a deflection instrument device with millimeter-wave radar is proposed to solve the above problems. Utility Model Content

At this time, dust and impurities in the air can easily adhere to the lens, thereby causing inaccurate observation data due to lens contamination. Therefore, manual cleaning of the lens is required at regular intervals. This method not only increases labor intensity, but also the manual cleaning force is difficult to control, which may cause lens damage.
[0005] To achieve the above object, the utility model provides the following technical solution: a deflectometer device with a millimeter wave radar, comprising a base, a rolling wheel is arranged on the base, a bottom support rod is fixedly welded on the base, and a telescopic sleeve rod is slidably connected to the bottom support rod;

DETAILED DESCRIPTION
[0031] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0032] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0033] In the description of the present utility model, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0035] See also Figure 1-6 The utility model provides a technical solution: a deflectometer device with a millimeter wave radar, comprising a base 1, a rolling wheel 2 is arranged on the base 1, a bottom support rod 3 is fixedly welded on the base 1, and a telescopic sleeve rod 4 is slidably connected to the bottom support rod 3;
[0036] A support plate 6 is fixedly welded on the telescopic sleeve rod 4, and a deflectometer body 7 is fixedly mounted on the support plate 6;
[0037] The telescopic sleeve rod 4 is threadedly connected with a fixing bolt 5;
[0038] A lens 8 is fixedly mounted on the deflectometer body 7, a support block 9 is fixedly mounted on one side of the deflectometer body 7 where the lens 8 is disposed, and a wiping cap 10 is disposed on the support block 9;
[0039] A cleaning mechanism is provided on the wiping cap 10. Through the provided cleaning mechanism, the lens 8 can be wiped and cleaned to avoid blurring of the lens 8 caused by dust adhesion, thereby ensuring the normal use of the instrument and the accuracy of the detection data;
[0040] When the height of the deflection meter body 7 needs to be adjusted, it is only necessary to pull the telescopic sleeve 4. At this time, the telescopic sleeve 4 slides on the bottom support rod 3. When the deflection meter body 7 moves to the specified height, the fixing bolt 5 is rotated to penetrate the telescopic sleeve 4 and contact the surface of the bottom support rod 3, thereby fixing the position of the deflection meter body 7.
[0041] Further, the cleaning mechanism includes a central shaft 15, which is rotatably connected to the center of the wiping cap 10;
[0042] A wiping plate 19 is fixedly connected to the central shaft 15, and a sponge 18 is bonded to the wiping plate 19;
[0043] A gear 16 is fixedly mounted on the central shaft 15, and a rack 14 is slidably connected inside the wiping cap 10;
[0044] The rack 14 is meshedly connected with the wiping cap 10;
[0045] A return spring 17 is fixedly connected inside the wiping cap 10, and the rack 14 is fixedly connected to the return spring 17;
[0046] When the rack 14 is pressed, the rack 14 is forced to retract into the interior of the wiping cap 10. At this time, as the rack 14 moves, the gear 16 drives the central shaft 15 to rotate. When the central shaft 15 rotates, the wiping plate 19 and the sponge 18 rotate together. Therefore, the sponge 18 wipes and cleans the dust and impurities on the surface of the lens 8, thereby completing the cleaning of the lens 8 during the opening process, thereby ensuring the normal use of the instrument without the need to clean it separately.
[0047] By providing the reset spring 17, the rack 14 has a good reset effect, so that it can be reset when not subjected to force, thereby facilitating the use of the cleaning mechanism next time.
[0048] Furthermore, a cap fixing plate 12 is fixedly mounted on the deflectometer body 7, and a limiting groove 13 is provided on the cap fixing plate 12;
[0049] The side of the cap fixing plate 12 close to the lens 8 is an inclined surface;
[0050] When it is necessary to cover and protect the lens 8 with the wiping cap 10, it is only necessary to rotate the wiping cap 10. As the wiping cap 10 rotates, the rack 14 contacts the inclined surface of the cap fixing plate 12. Therefore, as the pressure continues to be generated, the rack 14 is retracted into the interior of the wiping cap 10 again. When the rack 14 moves to the position where the limiting groove 13 is located, the reset spring 17 resets the rack 14 through its own elasticity, so that the rack 14 is stuck into the interior of the limiting groove 13, thereby fixing the wiping cap 10.
[0051] Furthermore, a rotational positioning shaft 11 is fixedly connected to the support block 9, and the wiping cap 10 is rotationally connected to the rotational positioning shaft 11;
[0052] The rotating positioning shaft 11 is in an I-shaped shape, and a torsion spring 20 is movably sleeved at the waist of the rotating positioning shaft 11. Two torsion arms of the torsion spring 20 are respectively fixedly connected to the inner wall of the wiping cap 10 and the rotating positioning shaft 11;
[0053] By providing the torsion spring 20 , when the rack 14 is disengaged from the limiting groove 13 , the wiping cap 10 can be automatically opened from the lens 8 due to the elasticity of the torsion spring 20 , thereby making it more convenient for operators to use.
[0054] Working principle: when the rack 14 is pressed, the rack 14 is forced to retract into the interior of the wiping cap 10. At this time, as the rack 14 moves, the gear 16 drives the central shaft 15 to rotate. When the central shaft 15 rotates, the wiping plate 19 and the sponge 18 rotate together. Therefore, the sponge 18 wipes and cleans the dust and impurities on the surface of the lens 8, thereby completing the cleaning of the lens 8 during the opening process, thereby ensuring the normal use of the instrument and no longer needing to clean it separately.
[0055] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
