Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction and testing technology, and in particular to a prestressed tensioning monitoring device system for aqueducts. Background Technology

[0002] The aqueduct prestressing tensioning monitoring device is used to monitor the stress state and deformation of an aqueduct during the prestressing tensioning process. This device primarily utilizes laser measurement technology, emitting a laser and observing the positional changes of the laser point on a receiving screen to reflect the aqueduct's deformation in real time.

[0003] As crucial hydraulic structures for transporting water resources, the stability of aqueducts directly impacts the safety and efficiency of water conservancy projects during construction and operation. Traditional methods for monitoring aqueduct deformation have several limitations. Firstly, some conventional monitoring methods rely on periodic manual measurements, which are not only inefficient but also highly susceptible to human factors, making real-time and continuous monitoring difficult. For example, manually measuring mid-span settlement using a level instrument involves long intervals, making it difficult to detect sudden deformations during these intervals. Secondly, existing automated monitoring equipment lacks adaptability to the complex and varied construction environments and different structural forms of aqueducts.

[0004] Especially during the prestressing tensioning process of aqueducts, factors such as different construction stages, varying ambient temperatures, and diverse aqueduct structural forms can lead to complex and dynamic deformation of the aqueduct. In such cases, traditional monitoring equipment cannot flexibly adjust monitoring parameters to adapt to different working conditions. For example, traditional fixed-height laser receiving devices cannot guarantee that the laser point is always accurately projected onto the receiving screen when the aqueduct undergoes varying degrees of upward or downward deformation due to prestressing tension, thus affecting the accuracy of aqueduct deformation monitoring. Utility Model Content

[0005] In order to overcome the shortcomings mentioned in the background art, this utility model provides a prestressed tensioning monitoring device system for aqueducts.

[0006] The technical implementation scheme of this utility model is as follows:

[0007] A prestressed tensioning monitoring system for an aqueduct includes a mounting plate, an aqueduct slab, handles, fixing plates, a housing, mounting blocks, laser emitters, alarm lights, cover shields, receiving screens, a controller, markers, and adjustment components. The mounting plate is mounted on top of the aqueduct slab, and fixing plates are symmetrically mounted on top of the mounting plate. The housing is installed between the two fixing plates. Handles are symmetrically connected to the top of the mounting plates. Laser emitters are symmetrically mounted on the top of the housing via mounting blocks. An alarm light is installed at the left rear corner and right front corner of the top of the housing. A cover shield is installed at the left front corner and right rear corner of the top of the housing. A receiving screen is slidably connected inside each cover shield, and a marker shield is connected to the center of each receiving screen. The laser emitters and receiving screens face opposite directions. A controller is mounted on the front side of the housing, and the laser emitters and alarm lights are electrically connected to the controller. Adjustment components are provided on the cover shields.

[0008] As a further preferred embodiment, the adjustment assembly includes a screw, an adjustment knob, and a connecting block. The screw is rotatably connected to the cover, with the top of the screw penetrating the cover and connected to the adjustment knob. The lower end of the screw is threadedly connected to the connecting block, which is slidably connected to the inside of the cover and connected to the top of the receiving screen.

[0009] As a further preferred embodiment, it also includes locking blocks and springs. Multiple locking blocks are slidably connected at intervals on the fixed plate, and each locking block is connected to the inside of the fixed plate by a spring. Locking holes are provided on the front and rear sides of the housing at positions aligned with the locking blocks, and the locking blocks engage with the locking holes.

[0010] As a further preferred option, it also includes fixing screws and nuts. Four fixing screws are connected in a rectangular pattern on the top of the aqueduct plate, and nuts are installed on the mounting plate at the positions corresponding to the fixing screws. The mounting plate is fixed by the cooperation of the nuts and fixing screws.

[0011] As a further preferred option, it also includes a solar panel and a storage battery. The solar panel is installed in the middle of the top of the casing, and the storage battery is installed inside the casing. Both the solar panel and the storage battery are electrically connected to the controller via a circuit.

[0012] As a further preferred option, a bubble level is also included, with bubble levels symmetrically mounted on the top of the mounting plate.

[0013] The beneficial effects of this application by adopting the above technical solution are:

[0014] 1. By using a laser transmitter and a laser receiver screen together, the position of the laser point can be accurately determined, which makes it easier for staff to accurately reflect the deformation of the cross section at the mid-span of the aqueduct; the height-adjustable receiver screen can flexibly adjust its height according to different construction stages, ambient temperature and aqueduct structure, ensuring that the laser point is always accurately projected onto the receiver screen, greatly improving the accuracy of deformation monitoring.

[0015] 2. The housing is snapped into the mounting plate by a clip, allowing the housing to be removed separately during maintenance without disassembling the entire mounting plate, thus simplifying the maintenance process and reducing maintenance costs. Attached Figure Description

Detailed Implementation

[0024] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0025] like Figures 1-4As shown, the aqueduct prestressing tension monitoring device system provided in this embodiment includes a mounting plate 1, an aqueduct plate 101, a handle 3, a fixing plate 4, a housing 5, a mounting block 6, a laser transmitter 7, an alarm light 8, a cover 9, a receiving screen 13, a controller 201, a marker 14, and an adjustment component.

[0026] The aqueduct plate 101 is equipped with a mounting plate 1 on top. A fixing plate 4 is symmetrically mounted on the top of the mounting plate 1, and a housing 5 is installed between the two fixing plates 4. Handles 3 are symmetrically welded to the top of the mounting plate 1, allowing the operator to lift the entire device. Laser emitters 7 are symmetrically mounted on the top of the housing 5 via mounting blocks 6. An alarm light 8 is installed at the left rear corner and right front corner of the top of the housing 5. A cover 9 is installed at the left front corner and right rear corner of the top of the housing 5. A receiving screen 13 is slidably connected inside each cover 9. The cover 9 blocks external light, increases contrast, and makes the laser point image on the receiving screen 13 clearer. A marker 14 is connected to the center of each receiving screen 13. The laser emitter 7 on the left faces backward, and the laser emitter 7 on the right faces forward. The two receiving screens 13 also face opposite directions, with the left facing forward and the right facing backward. A controller 201 is bolted to the front of the housing 5. The laser emitter 7, alarm light 8, and controller 201 are electrically connected. An adjustment component is provided on the cover 9.

[0027] In addition, scale lines can be set on the receiving screen 13 from top to bottom to facilitate reading by staff.

[0028] like Figures 3-4 As shown, the adjustment assembly includes a screw 10, an adjustment knob 11, and a connecting block 12. The screw 10 is rotatably connected to the cover 9. The top of the screw 10 passes through the cover 9 and is welded with the adjustment knob 11. The lower end of the screw 10 is threadedly connected to the connecting block 12. The connecting block 12 is slidably connected to the inside of the cover 9 and connected to the top of the receiving screen 13. By rotating the adjustment knob 11, the screw 10 can be rotated, thereby adjusting the height of the receiving screen 13 and the marker 14.

[0029] like Figures 1-2 As shown, it also includes fixing screws 102 and nuts 2. Four fixing screws 102 are welded in a rectangular pattern on the top of the aqueduct plate 101. Nuts 2 are installed on the mounting plate 1 at the positions corresponding to the fixing screws 102. The mounting plate 1 is fixed by the cooperation of the nuts 2 and the fixing screws 102. The height of the mounting plate 1 can be adjusted according to the actual installation requirements, thereby adjusting the height of the entire device.

[0030] When installing this device, the mid-span position is accurately determined first using precise measurement and calculation methods based on the mechanical characteristics of the actual aqueduct structure. Then, the aqueduct plate 101 is installed at the key load-bearing parts of the aqueduct. The mounting plate 1 is securely connected to the aqueduct plate 101 through the coordinated action of the fixing screws 102 and nuts 2. At the same time, the installation height is finely adjusted according to engineering requirements.

[0031] Based on the overall length plan of the aqueduct, multiple monitoring devices are reasonably arranged at specific intervals to ensure that each device is strictly on the same reference straight line, so as to ensure the continuity and accuracy of monitoring data. The two laser emitters 7 and the two receiving screens 13 of each device are set in opposite directions. The laser beam emitted by the laser emitter 7 can be accurately projected onto the receiving screen 13 of the adjacent device. By rotating the adjustment knob 11, the screw 10 is driven to rotate precisely, thereby driving the connecting block 12, the receiving screen 13 and the marker 14 to move smoothly in the vertical direction, so as to achieve precise height adjustment and ensure that the laser beam emitted by the laser emitter 7 can accurately hit the center position of the marker 14 on the receiving screen 13, so that the laser emitter 7 and the marker 14 are always on the same vertical line. The scale line arranged in the height direction on the receiving screen 13 is used to accurately read the actual position of the laser point on the receiving screen 13. To facilitate analysis by relevant personnel, during the prestressed tensioning construction process of the aqueduct, the laser position reading can intuitively reflect the upward or downward deformation of the mid-span section. The alarm light 8 can be triggered by the controller 201 to issue an audible and visual alarm to send early warning information to other staff. Construction personnel must immediately carry out tensioning operations on the prestressed steel strands at the top of the aqueduct to effectively control deformation.

[0032] Given the complex factors affecting the aqueduct's deformation during prestressing, including load variations at different construction stages, dynamic fluctuations in ambient temperature, and inherent differences in the aqueduct's structural form, the deformation exhibits a high degree of uncertainty. This device, equipped with a height-adjustable receiving screen 13, can flexibly and precisely adjust its height according to changes in actual working conditions. This ensures that the laser point is always accurately projected onto the receiving screen 13 under various complex circumstances, thereby achieving high-precision, all-around monitoring of the aqueduct's deformation and providing reliable data support and safety assurance for the aqueduct's prestressing tensioning construction.

[0033] like Figures 5-6As shown, it also includes a locking block 15 and a spring 16. Multiple locking blocks 15 are slidably connected on the fixing plate 4 at intervals. Each locking block 15 is connected to the inside of the fixing plate 4 by a spring 16. Locking holes 17 are provided on the front and rear sides of the housing 5 at positions aligned with the locking blocks 15. The locking blocks 15 and locking holes 17 engage to fix the housing 5. The end face of the locking block 15 is arc-shaped, which facilitates the engagement and disengagement of the locking block 15 and locking holes 17. When inspecting the device, the housing 5 can be removed directly without removing the entire mounting plate 1. When removing the housing 5, the locking blocks 15 are squeezed and compressed into the fixing plate 4, the spring 16 is compressed, and the locking blocks 15 disengage from the locking holes 17. When installing, align the locking holes 17 with the locking blocks 15 and press firmly to engage the locking holes 17 with the locking blocks 15.

[0034] like Figure 1 and Figure 7 As shown, it also includes a solar panel 18 and a storage battery 20. The solar panel 18 is bolted to the top center of the housing 5, and the storage battery 20 is bolted to the inside of the housing 5. Both the solar panel 18 and the storage battery 20 are electrically connected to the controller 201 through a circuit. The solar panel 18 receives sunlight and converts it into electrical energy. The electrical energy is processed and regulated by the controller 201 to ensure that the electrical energy is efficiently and stably transmitted to the storage battery 20 for storage. The electrical energy stored in the storage battery 20 provides a continuous and stable power supply for the electrical components in the device, such as the laser emitter 7 and the alarm light 8, thereby ensuring that the device can still operate normally in an environment without an external power source, greatly improving the ease of use and adaptability of the device to various application scenarios.

[0035] like Figure 1 As shown, the device also includes a bubble level 21. The bubble levels 21 are symmetrically installed on the top of the mounting plate 1. During the process of fixing the mounting plate 1 to the aqueduct plate 101, the operator can visually determine whether the device is installed horizontally by observing the position of the bubbles in the bubble level 21. If the bubbles deviate from the center position, it indicates that the device is tilted. The operator can adjust the mounting plate 1 in a timely manner according to the direction of the bubble deviation to ensure that the device is installed horizontally.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
