Description

Technical Field

[0001] The utility model relates to the technical field of aqueduct monitoring, in particular to a monitoring device based on aqueduct strain. Background Art

[0002] Aqueducts are overhead channels that carry water across rivers, valleys, depressions, and roads. They are commonly used for irrigation and water delivery, as well as for flood and sand drainage. Large aqueducts can also be navigable. Aqueducts are mainly built with materials such as stone masonry, concrete, and reinforced concrete. Aqueducts, also known as elevated canals or water bridges, are a water delivery system consisting of bridges, tunnels, or ditches. They are usually built over valleys, depressions, and rivers for water delivery, passage, and navigation. They are used to bring water from distant places to towns and villages with insufficient water for drinking and irrigation. During use, the strain of aqueducts needs to be monitored, but existing aqueduct-based strain monitoring devices still have some problems:

[0003] After long-term use, adjacent aqueducts are prone to unevenness, forming height differences. The traditional strain monitoring device installation structure is basically a vertical plane, which makes it difficult for the strain monitoring device to meet installation requirements. To this end, we have made improvements and proposed a monitoring device based on aqueduct strain. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a monitoring device based on aqueduct strain, which can be adapted to different installation environments by adjusting the length and height.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a monitoring device based on aqueduct strain, including a resistance strain gauge, wherein the four corners of the resistance strain gauge are provided with snap-on protrusions. The working principle of the resistance strain gauge is based on the strain effect, that is, when a conductor or semiconductor material is mechanically deformed under the action of an external force, its resistance value changes accordingly;

[0006] The strain gauge positioning frame includes a snap-in block adapted to the snap-in protrusion, wherein the snap-in block is plugged into the snap-in protrusion to fix the resistance strain gauge;

[0007] a strain gauge fixing member, mounted on the aqueduct to support the strain gauge positioning frame;

[0008] The strain gauge positioning frame can slide horizontally relative to the strain gauge positioning frame to adjust the relative distance between the buckle block and the strain gauge fixing piece.

[0009] Optionally, the resistance strain gauge is connected to a signal transmission module via a wire, and the signal transmission module is used to transmit data change information of the resistance strain gauge to a terminal device.

[0010] Optionally, through holes are opened on both sides of the strain gauge fixing part, and positioning screws are inserted into the through holes. The strain gauge fixing part is fixedly connected to the aqueduct through the positioning screws. The strain gauge fixing part can be fixed by the positioning screws to complete the effective fixation of the strain gauge fixing part.

[0011] Optionally, the tail end of the strain gauge fixing piece is threadedly connected with a clamping bolt, and the tail end of the strain gauge positioning frame is provided with a movable groove. After the clamping bolt passes through the movable groove, it engages with the thread of the strain gauge fixing piece so that the strain gauge positioning frame abuts against the strain gauge fixing piece and is in a stopped state.

[0012] Optionally, a sliding groove is provided at the front end of the strain gauge fixing piece, a disc slider is slidably connected to the inner wall of the sliding groove, a height adjustment bolt is provided on the top of the disc slider, a threaded hole is provided on the strain gauge positioning frame, and the height adjustment bolt is threadedly connected to the threaded hole.

[0013] Optionally, a balancing groove is provided at the bottom of the strain gauge positioning frame, and the strain gauge positioning frame is clamped on the outer wall of the strain gauge fixing component through the balancing groove.

[0014] Optionally, the cross section of the movable groove is U-shaped.

[0016] The utility model provides a monitoring device based on aqueduct strain, which has the following beneficial effects:

[0017] The monitoring device based on aqueduct strain is provided with a resistance strain gauge, a strain gauge positioning frame, a strain gauge fixing piece, a snap protrusion, a snap insert block, a clamping bolt and a height adjustment bolt. The two strain gauge fixing pieces are symmetrically arranged, and then the snap insert block at the bottom of the strain gauge positioning frame is inserted into the snap protrusion, so that the strain gauge positioning frame contacts the resistance strain gauge and the resistance strain gauge is snapped onto the aqueduct. For uneven installation scenarios, the position of the strain gauge positioning frame can be adjusted through the movable groove, and the height adjustment bolt can be rotated at the same time. Then, the height of the strain gauge positioning frame can be adapted to the corresponding installation scenario, thereby achieving installation adaptability in multiple scenarios.

[0024] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] See also Figures 1 to 5 The utility model provides a technical solution: a monitoring device based on aqueduct strain, comprising a resistance strain gauge 1, with snap-on protrusions 11 provided at the four corners of the resistance strain gauge 1. The working principle of the resistance strain gauge 1 is based on the strain effect, that is, when a conductor or semiconductor material is mechanically deformed under the action of an external force, its resistance value changes accordingly;

[0027] The strain gauge positioning frame 2 includes a snap-in block 21 adapted to the snap-in protrusion 11, and the snap-in block 21 is plugged into the snap-in protrusion 11 to fix the resistance strain gauge 1;

[0028] The strain gauge fixing member 3 is installed on the aqueduct to support the strain gauge positioning frame 2;

[0029] The strain gauge positioning frame 2 can slide horizontally relative to the strain gauge positioning frame 2 to adjust the relative distance between the buckle inserting block 21 and the strain gauge fixing member 3 .

[0030] As a preferred embodiment, based on the above manner, further, the resistance strain gauge 1 is connected to a signal transmission module through a wire, and the signal transmission module is used to transmit data change information of the resistance strain gauge 1 to the terminal device.

[0031] As a preferred embodiment, on the basis of the above-mentioned method, further, through holes 31 are opened on both sides of the strain gauge fixing member 3, and positioning screws 32 are inserted into the through holes 31. The strain gauge fixing member 3 is fixedly connected to the aqueduct through the positioning screws 32. The strain gauge fixing member 3 can be fixed by the positioning screws 32, thereby completing the effective fixation of the strain gauge fixing member 3.

[0032] The tail end of the strain gauge fixing part 3 is threadedly connected with a clamping bolt 33. The tail end of the strain gauge positioning frame 2 is provided with a movable groove 22. After the clamping bolt 33 is inserted into the movable groove 22, it is threadedly engaged with the strain gauge fixing part 3, so that the strain gauge positioning frame 2 contacts the strain gauge fixing part 3 and is in a stopped state.

[0033] A slide groove 34 is provided at the front end of the strain gauge fixing part 3, and a disc slider 35 is slidably connected to the inner wall of the slide groove 34. A height adjustment bolt 36 is provided on the top of the disc slider 35. A threaded hole 23 is provided on the strain gauge positioning frame 2, and the height adjustment bolt 36 is threadedly connected to the threaded hole 23. The advantage of using the disc slider 35 is that it is convenient for sliding in the slide groove 34, and there will be no impact when rotating the height adjustment bolt 36. A balancing groove 24 is provided at the bottom of the strain gauge positioning frame 2, and the strain gauge positioning frame 2 is clamped on the outer wall of the strain gauge fixing part 3 through the balancing groove 24. The advantage of this arrangement is that it is convenient for the strain gauge positioning frame 2 to slide and adjust on the strain gauge fixing part 3.

[0034] The cross section of the movable groove 22 is "U"-shaped, and there is a clearance fit between the snap block 21 and the snap protrusion 11. The inner diameter of the snap block 21 is larger than the outer diameter of the snap protrusion 11. The advantage of this arrangement is that the clamping bolt 33 can be embedded in the movable groove and can resist the strain gauge positioning frame 2, thereby completing the fixation of the strain gauge positioning frame 2.

[0035] In summary, when the monitoring device based on aqueduct strain is used, the two strain gauge fixing parts 3 are fixedly installed on the aqueduct by the positioning screws 32. When the position of the strain gauge positioning frame 2 needs to be adjusted, the clamping bolt 33 is rotated to release the restriction on the strain gauge positioning frame 2, and then the clamping bolt 33 is locked after the adjustment is completed, so that the clamping bolt 33 fixes the strain gauge positioning frame 2. When the height of the strain gauge positioning frame 2 needs to be adjusted, the height adjustment bolt 36 is rotated to raise or lower the height of the strain gauge positioning frame 2, and then the resistance strain gauge 1 is fixed by the strain gauge positioning frame 2, thereby achieving installation adaptability in multiple scenarios.
