Abstract
Description
Technical Field
[0001] This utility model relates to the field of dam slope detection technology, and more specifically, to a device for detecting the slope of a dam body. Background Technology
[0002] As a core water conservancy facility for flood control, water storage, and water management, the slope of the dam body is a key technical parameter determining its structural stability and safety performance. If the slope is too gentle, it can easily lead to increased erosion and siltation on the upstream side of the dam, increasing the load on the dam body. If the slope is too steep, it may cause insufficient shear strength of the dam slope soil, inducing major safety accidents such as seepage, landslides, or even dam failure. Therefore, accurate measurement of the dam body slope is a core element in ensuring the long-term safe operation of dams during construction, operation, maintenance, and regular safety inspections.
[0003] Currently, the industry's methods for detecting the slope of dam surfaces still mainly rely on traditional manual operations or simple devices. For example, patent CN211317293U discloses a dam slope detection device for hydraulic construction, which uses a moving body, telescopic rod, and level plate to detect the dam slope. However, this device relies on the position of an air bubble on the level plate to determine the slope, and the position of the air bubble is greatly affected by the operator's levelness and the flatness of the dam surface, making it difficult to ensure a stable measurement benchmark. Another example is some manual handheld tool detection methods, which use a handheld level, measuring tape, and angle gauge for measurement. This not only relies on the operator's experience but is also greatly affected by the on-site environment of the dam. Therefore, there is an urgent need for a slope detection device with intuitive readings to overcome the limitations of traditional detection methods. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dam body slope detection device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dam body slope detection device, comprising a base plate, with movable wheels fixedly installed at the four corners of the bottom of the base plate, and handrails fixedly installed on both sides of the top of the base plate, and further comprising:
[0006] A vertical pole that is fixedly installed on the top of the base plate and has a mounting groove at the top;
[0007] Testing equipment used to detect the slope of dam surfaces includes:

[0011] And a ring fixedly installed on the upright, with scale lines machined on the outer wall of the ring.

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] See attached document Figure 1 This embodiment of a dam slope detection device includes a base plate 1, a vertical pole 4, and a detection mechanism 5. Four movable wheels 2 are fixedly installed at the four corners of the bottom of the base plate 1. These wheels facilitate movement of the device on the dam slope by the operator, allowing for easy switching between different detection points. When slope detection is required, the operator can stop pushing the device to maintain its stability on the dam slope. Handrails 3 are fixedly installed on both sides of the top of the base plate 1 to facilitate pushing the device by the operator.
[0030] See attached document Figure 1 The upright 4 is fixedly installed on the top of the base plate 1, and the top end is provided with an installation groove 41. The base plate 1 and the upright 4 are set vertically, and the upright 4 is perpendicular to the base plate 1, that is, perpendicular to the dam body slope.
[0031] See attached document Figure 2 and Figure 3The detection mechanism 5 is used to detect the slope of the dam body. It includes a horizontal bar 51 fixedly installed in the installation groove 41. The horizontal bar 51 is vertically set with the vertical pole 4 and is located on the vertical center plane of the vertical pole 4. A connecting ring 52 that can rotate around the horizontal bar 51 is sleeved on the horizontal bar 51. The connecting ring 52 rotates by itself, which drives the steel wire 53 to freely adjust its angle according to the gravity direction of the counterweight 54, ensuring that the steel wire 53 always fits the gravity direction, that is, always perpendicular to the horizontal plane. The steel wire 53 is fixedly installed on the connecting ring 52. The end of the steel wire 53 is fixedly connected to the counterweight 54. The steel wire 53 and the counterweight 54 form a gravity reference component. The counterweight 54 is always vertically downward under the action of gravity, that is, always perpendicular to the horizontal plane. The gravity direction is transmitted as a visible reference line through the steel wire 53.
[0032] The testing mechanism 5 also includes a ring 55 fixedly installed on the upright 4. The cross section of the crossbar 51 is circular. The ring 55 and the crossbar 51 are set on the same axis to avoid reading deviation caused by different axes. The outer wall of the ring 55 is machined with scale lines 56, which are 0° to 360°. The 0° scale is set on the vertical center surface of the upright 4 to avoid measurement error.
[0033] See attached document Figure 4 When the operator places the device on the dam slope, under the gravity of the counterweight 54, both the steel wire 53 and the counterweight 54 are vertically downward. At this time, the angle between the steel wire 53 and the vertical center plane of the upright 4 is recorded as ∠α, the slope of the dam slope is recorded as ∠β, and the angles between the steel wire 53 and the slope are recorded as ∠γ1 and ∠γ2 respectively. Since ∠γ1=∠γ2, ∠α=∠β. That is, the scale indicated by the steel wire 53 is the slope of the dam slope.
[0034] In actual operation, the operator pushes the device through the handle 3 and places it on the dam slope to be tested. After stopping the push, the device remains stable, with the base plate 1 parallel to the slope. At this time, the upright 4 is perpendicular to the slope. Under the gravity of the counterweight 54, the steel wire 53 and the counterweight 54 together remain perpendicular to the horizontal plane. Since the 0° scale of the ring 55 is aligned with the vertical center of the upright 4, the steel wire 53 points to a certain scale of the ring 55 under the action of gravity. This scale value is the size of ∠α. The slope of the dam slope ∠β is equal to the value of ∠α. The operator can directly read the scale value pointed to by the steel wire 53 to obtain the actual slope of the dam slope.
[0035] In other embodiments, two rings 55 are provided. The two rings 55 are of the same specification and are coaxially arranged. The two rings 55 are respectively located on both sides of the upright 4. The steel wire 53 is located between the two rings 55. When the field of view on both sides of the device is different, such as when one side is blocked by a dam protrusion, the double rings 55 located on both sides of the upright 4 allow the operator to take the reading on the unobstructed side without moving the device to adjust its position. This ensures the accuracy of the reading and improves the applicability in complex dam environments.
[0036] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
