Description

Technical Field

[0001] This utility model belongs to the technical field of dam testing devices, specifically relating to a dam slope on-site acceptance data measurement device. Background Technology

[0002] As a key component of water conservancy projects, dams play numerous important roles. During flood season, they intercept floodwaters, regulate river flow, mitigate flood disasters for downstream areas, and protect people's lives, property, and infrastructure. Simultaneously, they store water resources, providing a stable water source for farmland irrigation, improving agricultural productivity, and safeguarding food security.

[0003] Among the various design standards for dams, the accuracy of the slope is directly related to the stability and safety of the dam. Therefore, on-site acceptance is required, and rectification should be carried out based on the acceptance results. Existing technology, Chinese patent application number "CN202223064576.3" discloses a slope detection device, which is equipped with an adjustment mechanism. When using it, the slope value at a certain point can only be calculated based on the extension distance of the first side rod and the descent height of the auxiliary weight-bearing plumb bob. However, the extension distance of the first side rod needs to be manually adjusted, and the initial position of the weight-bearing plumb bob also needs to be adjusted, resulting in poor overall measurement efficiency when measuring data at multiple points. Utility Model Content

[0004] This invention addresses the problem in the prior art where the device requires calculation based on the extension distance of the first side rod and the descent height of the auxiliary weight-bearing plumb bob to determine the slope value at a given point. Furthermore, the extension distance of the first side rod needs manual adjustment, and the initial position of the weight-bearing plumb bob also needs adjustment, leading to inefficiency when measuring data at multiple points. This invention provides a field acceptance data measurement device for dam slope.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dam slope on-site acceptance data measuring device, comprising a base, a measuring rod hinged to one end of the base via a rotating shaft, a digital angle ruler set between the base and the measuring rod for automatically reading the dam slope value, and at least one extension rod installed on the measuring rod.

[0006] As a further supplement to the above technical solution, the extension rod is mounted on the measuring rod via a sliding assembly to achieve automatic extension of the extension rod.

[0007] As a further explanation and limitation of the above technical solution, the sliding assembly consists of a dual-axis motor, rollers, traction ropes, and limiting grooves. The dual-axis motor is installed in the measuring rod located on one side of the base. Rollers are installed on the output shaft ends of the dual-axis motor. Traction ropes are wound inside the rollers. Limiting grooves are provided in the measuring rod on the side away from the base. The traction ropes pass around the limiting grooves and are fixed to both sides of the extension rod.

[0008] As a further explanation and limitation of the above technical solution, the sliding assembly consists of a stepper motor, a lead screw, and a nut seat. The stepper motor is installed inside the measuring rod, the output shaft end of the stepper motor is equipped with a lead screw, the lead screw is equipped with a nut seat, and the nut seat is fixed on the extension rod.

[0009] As a further supplement to the above technical solution, a support rod is rotatably provided on the extension rod, and a pulley is installed at the other end of the support rod.

[0010] As a further supplement to the above technical solution, a limiting component is installed at the connection end between the support rod and the extension rod. The limiting component is used to ensure that the support rod and the extension rod are in a vertical position during the measurement process.

[0011] As a further explanation and limitation of the above technical solution, the limiting component includes a limiting cover, a groove, a limiting rod, and a spring. The limiting cover abuts against the outer side of the connection end between the support rod and the extension rod. Grooves are evenly distributed on the contact back of the limiting cover and the support rod. The limiting rod is embedded in the groove. The two ends of the limiting rod are connected to the extension rod through springs. The springs are used to hold the limiting rod in the groove.

[0012] As a further supplement to the above technical solution, a locking component is installed on the base, which is used to lock the measuring rod inside the base.

[0013] As a further explanation and limitation of the above technical solution, the locking component includes an L-shaped pressure plate, which is rotatably connected to the other end of the base. A slot is provided on the base, and the L-shaped pressure plate is locked in the slot by rotation.

[0014] As a further supplement to the above technical solution, a handle is installed on the base, which facilitates the overall handling by the measuring personnel.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This utility model allows for a direct view of the dam's slope value by installing a digital angle gauge between the measuring rod and the base. During measurement, the surveyor uses a sliding component to extend the extension rod from the measuring rod, increasing its length along the slope, thus shortening the device adjustment time and improving measurement efficiency.

[0017] 2. This utility model is designed with a limiting component. Through the cooperation of the limiting cover and the locking rod, the angle of the support rod and the extension rod is fixed. During the measurement process, the support rod and the extension rod are ensured to be perpendicular, and during the storage process, the support rod and the extension rod are ensured to be horizontal.

[0018] 3. This utility model is designed with a locking component. When the measuring rod is screwed into the base, the L-shaped pressure plate ensures that the measuring rod and the extension rod cannot slide out of the base, which facilitates transportation. Attached Figure Description

[0026] To further illustrate the technical solution of this utility model, the following description is in conjunction with the appendix. Figures 1 to 6 The present invention will be further described in detail through four embodiments.

[0027] Example 1

[0028] As attached Figure 1 and attached Figure 2As shown, a dam slope on-site acceptance data measurement device includes a base 1. A measuring rod 3 is hinged to one end of the base 1 via a rotating shaft 2. A digital angle ruler 4 is positioned between the base 1 and the measuring rod 3. Specifically, the two straight sections of the digital angle ruler 4 are fixed to the same side of the base 1 and the measuring rod 3, respectively. On-site surveyors can directly and automatically read the dam slope value using the digital angle ruler 4. In this embodiment, the digital angle ruler 4 can be obtained as a readily available product. Furthermore, to increase numerical accuracy, at least one extension rod 5 is installed on the measuring rod 3, extending its length to improve measurement accuracy.

[0029] Example 2

[0030] To achieve automatic extension of extension rod 5, as shown in the attached... Figure 3 and attached Figure 4 As shown, in practical applications, the extension rod 5 is mounted on the measuring rod 3 via the sliding assembly 6. Furthermore, we provide two structures for the sliding assembly 6. The first type of sliding assembly 6 consists of a dual-axis motor 601, rollers 602, a traction rope 603, and a limiting groove 604. The dual-axis motor 601 is installed inside the measuring rod 3 on one side of the base 1. Rollers 602 are installed on the output shafts of the dual-axis motor 601, and the traction rope 603 is wound inside the rollers 602. A limiting groove 604 is provided inside the measuring rod 3 on the side away from the base 1. The traction rope 603 passes around the limiting groove 604 and is fixed to both sides of the extension rod 5. The dual-axis motor 801 drives the rollers 802 to rotate. Then, the rotation of the rollers 802 winds the traction rope 803 around the surface of the rollers 802. Finally, the other end of the traction rope 803 pulls the extension rod 5 out of the measuring rod 3. The second type of sliding component 6 consists of a stepper motor 605, a lead screw 606, and a nut seat 607. The stepper motor 605 is installed inside the measuring rod 3. The lead screw 606 is installed on the output shaft end of the stepper motor 605. The nut seat 607 is installed on the lead screw 606 and fixed to the extension rod 5. The stepper motor 805 drives the lead screw 806 to rotate. Then, the rotation of the lead screw 806 causes the nut seat 807 to move along the lead screw 806. Then, the nut seat 807 drives the extension rod 5 to extend out of the measuring rod 3.

[0031] Example 3

[0032] To facilitate the movement of extension rod 5 along the dam surface, as shown in the attached... Figure 1 As shown, a support rod 7 is rotatably mounted on the extension rod 5, and a pulley 8 is installed at the other end of the support rod 7.

[0033] To ensure that the support rod 7 and the extension rod 5 are in a vertical position during the measurement process, as shown in the attached figure... Figure 4As shown, a limiting component 9 is installed at the connection end between the support rod 7 and the extension rod 5. The limiting component 9 includes a limiting cover 901, a groove 902, a limiting rod 903, and a spring 904. The limiting cover 901 abuts against the outside of the connection end between the support rod 7 and the extension rod 5. Grooves 902 are evenly distributed on the back side of the limiting cover 901 that contacts the support rod 7. The limiting rod 903 is embedded in the groove 902. The two ends of the limiting rod 903 are connected to the extension rod 5 through the spring 904. The spring 904 is used to lock the limiting rod 903 in the groove 902.

[0034] Example 4

[0035] To lock the measuring rod 3 inside the base 1, as shown in the attached... Figure 6 As shown, a locking assembly 10 is installed on the base 1. The locking assembly 10 includes an L-shaped pressure plate 1001, which is rotatably connected to the other end of the base 1. A slot 1002 is provided on the base 1, and the L-shaped pressure plate 1001 is locked in the slot 1002 by rotation.

[0036] For easy transport of base 1, see attached Figure 1 As shown, we have installed a handle 11 on the base 1 to make it easy to lift the base 1.

[0037] Its specific usage:

[0038] First, lift the base 1 to the sampling point using the handle 11 and place it horizontally at the bottom of the dam slope. Then, pry the L-shaped pressure plate 1001 out of the slot 1002 and rotate the measuring rod 3 out of the base 1. Next, vertically pull up the limiting rod 903 and rotate the support rod 6 to a position perpendicular to the measuring rod 3. The limiting cover 901 rotates with the support rod 6. Then, release the limiting rod 903, and under the tension of the spring 904, it is embedded in the groove 902, keeping the support rod 6 perpendicular to the measuring rod 3.

[0039] After the pulley 7 on the support rod 6 contacts the slope surface, the on-site surveyor pushes the base 1 along a direction perpendicular to the dam, while simultaneously observing the value on the digital angle scale 4. This continues until the value on the digital angle scale 4 displays the design slope value. Then, the extension rod 5 is driven by the sliding component 6 to extend uniformly from the measuring rod 3, and the value on the digital angle scale 4 is observed again. The conclusions are as follows: When the value remains consistently at the design slope value, the slope at that sampling point meets the requirements; when the value increases, the slope at the contact point between the pulley 7 and the dam body is greater than the design value, which does not meet the requirements; when the value decreases, the slope at the contact point between the pulley 7 and the dam body is less than the design value, which also does not meet the requirements.
