Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering surveying and mapping technology, specifically relating to a water conservancy engineering dam deformation monitoring and mapping device that is easy to store. Background Technology

[0002] In the field of water conservancy projects, dams are critical infrastructure, and their safety is of paramount importance. Since dams are usually built of concrete, they are subject to a variety of complex factors such as water flow impact, water level changes, and geological movements over a long period of time, making them extremely prone to deformation. If serious deformation of a dam is not detected in time, it may lead to major safety accidents such as dam failure, causing devastating damage to the lives and property of people downstream and the ecological environment. Therefore, it is necessary to regularly detect the deformation of dams using surveying equipment.

[0003] Existing surveying devices used for monitoring dam deformation in water conservancy projects mostly adopt a traditional three-support structure. While this design can meet basic measurement needs to a certain extent, in practical applications, the compact structure of the three-support surveying device itself does not reserve space specifically for placing auxiliary items. In dam deformation monitoring surveying work, various auxiliary tools are often required, and the lack of reasonable placement space for these tools leads to them being placed haphazardly on the work site. This not only easily causes tools to be lost or damaged but also makes the work area cluttered, seriously affecting the work efficiency and ease of operation for surveyors. Secondly, to solve the problem of placing auxiliary items, some technicians have tried to set up additional placement devices. However, most of these additional devices are not designed with the convenience of storage in mind. When the surveying task is completed and the work site needs to be moved or the work is finished and the items need to be stored, these additional placement devices often cannot be stored quickly and effectively, and occupy a lot of space, increasing the difficulty and cost of transportation and storage. Utility Model Content

[0004] The purpose of this invention is to provide a storage-friendly device for monitoring and mapping the deformation of water conservancy dams, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a storage-friendly device for monitoring and mapping the deformation of a hydraulic engineering dam, comprising:

[0006] A storage box with a hinged door on its surface. The storage box is divided into a storage slot and a lifting slot by a partition. The lifting slot is equipped with a lifting component for raising and lowering the surveyor. The first bevel gear and the second bevel gear of the lifting component mesh and drive the lead screw to rotate, so that the rotating lead screw drives the lifting rod to move out of the sleeve rod to adjust the height of the surveyor.

[0007] A mounting base is connected to the top of the lifting rod and is used to fix the surveyor.

[0008] Preferably, the lifting assembly includes a motor, the sleeve is connected to the lifting groove and one end of the sleeve passes through the storage box, and the lead screw is rotatably connected to the sleeve through a bearing.

[0009] Preferably, the lifting rod is connected to the surface of the lead screw via a lead screw nut, the second bevel gear is fixedly fitted onto one end of the bottom of the lead screw, and the first bevel gear is also rotatably connected to the bottom of the sleeve rod via a bearing.

[0010] Preferably, the motor is mounted on the surface of the sleeve rod, and the output shaft of the motor rotates through the sleeve rod and connects to the first bevel gear. The two ends of the lifting rod are slidably connected to the sliding grooves inside the sleeve rod via sliders.

[0011] Preferably, the fixing base is provided with a T-shaped groove, and the bottom of the surveyor is connected to a T-shaped block, which is inserted into the T-shaped groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The device is equipped with a storage box, which is divided into a storage slot and a lifting slot by a partition. The storage slot can be used to store various auxiliary tools, such as measuring rulers, recording boards, spare batteries, etc. After the surveying work is completed, the surveyor can be removed from the fixed base and stored in the storage box, reducing the space occupied and facilitating transportation and storage.

[0017] (2) A lifting assembly is adopted. The first bevel gear is driven to rotate by the motor. The first bevel gear meshes with the second bevel gear to drive the lead screw to rotate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-4 The device shown is a conveniently stored dam deformation monitoring and mapping device for water conservancy projects, comprising:

[0026] Storage box 1, with a door 2 hinged to its surface. Storage box 1 is divided into storage slot 4 and lifting slot 5 by partition 3. Lifting slot 5 is provided with lifting assembly for lifting the surveyor 6. The first bevel gear 7 and the second bevel gear 8 of the lifting assembly mesh and drive the lead screw 9 to rotate, so that the rotating lead screw 9 drives the lifting rod 10 to move out of the sleeve rod 11 to adjust the height of the surveyor 6.

[0027] The fixed base 12 is connected to the top of the lifting rod 10 and is used to fix the surveyor 6.

[0028] The lifting assembly includes a motor 13, the sleeve rod 11 is connected to the lifting groove 5 and one end of the sleeve rod 11 passes through the storage box 1, and the lead screw 9 is rotatably connected to the sleeve rod 11 through the bearing 22.

[0029] The lifting rod 10 is connected to the surface of the lead screw 9 via a lead screw nut. The second bevel gear 8 is fixedly fitted onto the bottom end of the lead screw 9. The first bevel gear 7 is also rotatably connected to the bottom of the sleeve rod 11 via a bearing 22.

[0030] The motor 13 is mounted on the surface of the sleeve rod 11, and the output shaft of the motor 13 rotates through the sleeve rod 11 and connects to the first bevel gear 7. The two ends of the lifting rod 10 are slidably connected to the sliding groove 15 inside the sleeve rod 11 through the slider 14. The cooperation between the slider 14 and the sliding groove 15 can effectively prevent the lifting rod 10 from shaking or deviating, and enhance the stability of the movement of the lifting rod 10.

[0031] The fixed base 12 is provided with a T-shaped groove 16, and the bottom of the measuring device 6 is connected to a T-shaped block 17. The T-shaped block 17 is inserted into the T-shaped groove 16 in the fixed base 12, which can initially position the measuring device 6.

[0032] The fixed base 12 is slidably connected to clamping blocks 18 at both ends. The fixed base 12 is provided with electric push rods 19 on both sides, and one end of the electric push rod 19 is connected to the clamping block 18. The top and bottom ends of the clamping block 18 are connected to guide rods 23, and the other end of the guide rod 23 slides through the fixed base 12.

[0033] The surface of the clamping block 18 is connected to a protective pad 20. The protective pad 20 is made of rubber and has a certain degree of elasticity and softness, which can prevent the clamping block 18 from directly rubbing against the surveyor 6 and effectively protect the surveyor 6.

[0034] The surface of the storage box 1 is equipped with a liquid level gauge 21, which can visually display whether the storage box 1 and the entire surveying device are in a horizontal state.

[0035] This easy-to-store water conservancy dam deformation monitoring and mapping device, when dam deformation monitoring and mapping work is required, opens the door 2 of the storage box 1, takes out the mapping device 6 from the storage slot 4, places the mapping device 6 on the fixed base 12, and inserts the T-shaped block 17 at the bottom of the mapping device 6 into the T-shaped slot 16 in the fixed base 12 to initially position the mapping device 6. At this time, the electric push rod 19 can be controlled by the external controller to work. The electric push rod 19 pushes the clamping block 18 to move closer to the mapping device 6. When the clamping block 18 moves, the guide rods 23 at both ends can guide the movement direction of the clamping block 18 to enhance the stability of the movement of the clamping block 18. The two sets of clamping blocks 18 close to each other can clamp the mapping device 6, and the protective pad 20 on the surface of the clamping block 18 can prevent the clamping block 18 from scratching the mapping device 6, while increasing the friction, so that the mapping device 6 is stably installed on the top of the lifting rod 10.

[0036] When the measuring device 6 is stably installed on the fixed base 12, the motor 13 can be controlled by an external controller. The output shaft of the motor 13 drives the first bevel gear 7 to rotate. Since the first bevel gear 7 meshes with the second bevel gear 8, the second bevel gear 8 will rotate accordingly. The rotating second bevel gear 8 can drive the lead screw 9 to rotate accordingly. When the lead screw 9 rotates, the lifting rod 10, which is connected to the lead screw 9 through the lead screw nut, will move when the lead screw 9 rotates. Under the action of the sliders 14 on both sides, the lifting rod 10 moves upward along the sliding groove 15 in the sleeve 11. The lifting rod 10 is moved to ensure its smooth movement, thereby raising the measuring device 6 to adapt to different measurement environments and requirements. After adjusting to a suitable monitoring height and completing the mapping work, the motor 13 is controlled to work in reverse by an external controller. The output shaft of the motor 13 drives the lead screw 9 to reverse, and the lifting rod 10 moves downward under the action of gravity and the lead screw 9, causing the lifting rod 10 to retract into the sleeve rod 11. Then the measuring device 6 can be removed from the fixed base 12 and stored in the storage box 1 to realize the storage of the device.

[0037] Proximity sensors 24 (or proximity switches) are installed at both the top and bottom of the slide 15. When the slider 14 approaches the proximity sensor at the top of the slide 15, the proximity sensor can sense the change in the magnetic field or capacitance of the slider 14, thereby generating an electrical signal. This signal is transmitted to the control system of the motor 13, and the control system commands the motor 13 to stop running according to the signal. Similarly, when the slider 14 approaches the proximity sensor at the bottom of the slide 15, the control system can also command the motor 13 to stop running according to the signal.

[0038] When placing the storage box 1, the liquid level indicator 21 on the surface of the storage box 1 can be observed. By adjusting the position of the storage box 1, the bubble in the liquid level indicator 21 is centered. At this time, the device is in a horizontal state. Only when the device is in a horizontal state can the data measured by the measuring instrument 6 be more accurate, thereby ensuring the accuracy of the dam deformation monitoring and mapping work.

[0039] The surveying instrument 6 of this utility model is a high-precision total station structure. It mainly consists of an electronic angle measuring system, an electro-optical distance measuring system, a microprocessor, a display screen, a base, and a telescope. The electronic angle measuring system can accurately measure horizontal and vertical angles, providing precise data for monitoring changes in dam deformation angles. The electro-optical distance measuring system, based on infrared or laser distance measuring principles, can measure the distance to target points with an accuracy of millimeters to centimeters, meeting the measurement needs for distance changes in different parts of the dam. The microprocessor is used to process and analyze measurement data and control various functions of the instrument. The telescope helps operators aim at target points and clearly observe the details of the dam. Thus, multiple key parts of the dam body can be measured, such as the dam crest, dam slope, and dam foundation. At the dam crest, by measuring the changes in distance and angle between different points, it is possible to monitor whether there is stretching, displacement, or other deformation at the dam crest.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
