Description

Technical Field

[0001] The present invention belongs to the technical field of water conservancy construction, and particularly relates to a slope degree measuring device for water conservancy construction. Background Art

[0002] The main function of the slope degree measuring device for water conservancy construction is to quickly and accurately measure the slope angle and slope degree, so as to ensure the stability and safety of water conservancy projects.

[0003] There is a slope degree detection device for water conservancy construction with the publication number of CN220062991U. In order to avoid damaging the protractor during the carrying process due to shaking or the misoperation of the carrier, which may cause the protractor to be unable to be used normally and affect the accuracy of the measurement reading, a storage box is provided. When using the slope degree detection device for water conservancy construction, the protractor, the suspension rope and the plumb bob are assembled on site. After use, the protractor, the suspension rope and the plumb bob are disassembled and put into the storage box, so as to protect the slope degree detection device for water conservancy construction and avoid damaging the protractor when carrying the slope degree detection device for water conservancy construction.

[0004] Although the above method can protect the important components of the slope degree detection device for water conservancy construction, such as the protractor, in the storage box when carrying the slope degree detection device for water conservancy construction, the components such as the protractor, the suspension rope and the plumb bob need to be installed and disassembled before and after each use. Installing and disassembling the components such as the protractor, the suspension rope and the plumb bob takes time, and the installation accuracy also affects the measurement result. Therefore, the existing slope degree measuring device for water conservancy construction is not convenient to use. Summary of the Invention

[0005] The purpose of the embodiment of the present invention is to provide a slope degree measuring device for water conservancy construction, aiming at solving the problem that the existing slope degree detection device for water conservancy construction needs to install and disassemble components such as the protractor, the suspension rope and the plumb bob before and after each use. Installing and disassembling the components such as the protractor, the suspension rope and the plumb bob takes time, and the installation accuracy also affects the measurement result, resulting in the inconvenience of using the existing slope degree measuring device for water conservancy construction.

[0006] The present invention is implemented as follows. A slope measurement device for water conservancy construction includes a protective bottom shell and a cover plate above the protective bottom shell. It further includes: a mounting shaft rotatably connected to the lower end of the cover plate. A C-shaped mounting plate is fixed on the mounting shaft, and a scale plate is fixed on the C-shaped mounting plate, with a gap left between the scale plate and the C-shaped mounting plate. A suspension rope is arranged at the lower end of the cover plate, and a plumb bob is fixed at the end of the suspension rope. The suspension rope is located between the scale plate and the C-shaped mounting plate. A telescopic support mechanism is arranged between the protective bottom shell and the cover plate, and the telescopic support mechanism drives the cover plate to move away from or close to the protective bottom shell by telescoping. A transmission mechanism is arranged at the lower end of the cover plate. When the cover plate moves close to or away from the protective bottom shell, the transmission mechanism drives the mounting shaft to rotate.

[0007] Further technical solution: The telescopic support mechanism includes two first rotating shafts rotatably connected to the side wall of the protective bottom shell, and a first connecting rod and a first gear fixed on each of the two first rotating shafts. The two first gears are meshed with each other. The ends of the two first connecting rods are rotatably connected to a second connecting rod respectively, and the middle parts of the two second connecting rods are rotatably connected. The ends of the two second connecting rods are rotatably connected to a third connecting rod respectively, and the ends of the two third connecting rods are fixed with a second rotating shaft respectively. The two second rotating shafts are rotatably connected to the lower end of the cover plate. A limiting component is arranged on the cover plate, and the limiting component is used to limit the rotation of one of the second rotating shafts.

[0008] Further technical solution: The limiting component includes a guiding groove vertically arranged in the cover plate and a guiding block slidably connected in the guiding groove. One end of the guiding block is fixed with a first compression spring and a pulling cap, and the other end of the guiding block is fixed with a limiting rod. Two limiting sunk grooves cooperating with the limiting rod are arranged on one of the second rotating shafts.

[0009] Further technical solution: The transmission mechanism includes a chute horizontally arranged at the lower end of the cover plate and a rack slidably connected in the chute. A second gear is fixed on the other second rotating shaft, and the second gear is meshed with the rack. One end of the mounting shaft is connected with a rotating shaft, and a third gear is fixed on the rotating shaft, and the third gear is meshed with the rack.

[0010] Further technical solution: A torsion spring is fixed on the rotating shaft, and the end of the torsion spring is fixed on the mounting shaft. An arc-shaped slider is fixed at one end of the mounting shaft. A C-shaped groove is arranged at the end of the rotating shaft close to the mounting shaft, and the arc-shaped slider is slidably connected in the C-shaped groove.

[0011] Further technical solution: on one side of the C-shaped mounting plate close to the scale plate, there is a C-shaped sliding groove. A first sliding block is slidably connected in the C-shaped sliding groove. A through hole is provided on the first sliding block. The suspension rope passes through the through hole. A plurality of limiting holes are evenly arranged in the C-shaped sliding groove. A sliding groove is provided in the first sliding block. A second sliding block is slidably connected in the sliding groove. One end of the second sliding block is fixed with a second compression spring and a limiting shaft. The limiting shaft cooperates with the limiting hole. A pushing assembly is provided on the first sliding block. The pushing assembly is used to drive the limiting shaft to insert into the limiting hole.

[0012] Further technical solution: the pushing assembly includes a winding sleeve fixed at the lower end of the sealing cover plate. One end of the suspension rope is fixed on the winding sleeve. A conical pushing surface is provided on the plumb bob. A pushing block is fixed at the other end of the second sliding block. The pushing block cooperates with the conical pushing surface.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. Compared with the existing assembled slope measurement device for water conservancy construction, which requires the installation and disassembly of the scale plate, suspension rope and plumb bob before and after use to protect the scale plate, suspension rope and plumb bob, the present invention can take out or put the scale plate, suspension rope and plumb bob into the protective bottom shell by opening and closing the sealing cover plate on the protective bottom shell, and can automatically drive the scale plate to rotate to the working state or the storage state without the need for cumbersome installation and disassembly of the scale plate, suspension rope and plumb bob, so as to protect the scale plate, suspension rope and plumb bob when not in use, thus facilitating the use of the slope measurement device for water conservancy construction;

[0015] 2. Through the setting of the torsion spring, C-shaped groove and arc-shaped slider, while the rotating shaft drives the mounting shaft to rotate, the relative rotation between the rotating shaft and the mounting shaft can also be realized. Furthermore, before the C-shaped mounting plate and the scale plate are put into the protective bottom shell, the C-shaped mounting plate and the scale plate can be in a horizontal storage state in advance, which is convenient for the storage of the C-shaped mounting plate and the scale plate. And when the C-shaped mounting plate and the scale plate are used, after the C-shaped mounting plate and the scale plate are separated from the protective bottom shell, the C-shaped mounting plate and the scale plate will rotate downward, which is convenient for the storage and unfolding use of the C-shaped mounting plate and the scale plate;

[0016] 3. The sealing cover plate moves towards the protective bottom shell, the mounting shaft drives the C-shaped mounting plate and the scale plate to rotate, and the rotating C-shaped mounting plate and scale plate wind up the suspension rope on the winding sleeve, reducing the length of the suspension rope. The suspension rope pulls the plumb bob towards the first sliding block, and the conical pushing surface of the plumb bob pushes the pushing block, thereby enabling the second sliding block to overcome the elastic force of the second compression spring and drive the limiting shaft to move. The limiting shaft is inserted into the limiting hole, thus restricting the movement of the first sliding block, and further locking the position of the plumb bob, avoiding the plumb bob from shaking during storage and preventing the shaking plumb bob from hitting the scale plate when carrying the slope degree measuring device for water conservancy construction, facilitating the storage of the slope degree measuring device for water conservancy construction.

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0030] As Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, a slope degree measuring device for water conservancy construction provided by an embodiment of the present invention includes a protective bottom shell 101, and a cover plate 102 above the protective bottom shell 101. It further includes: a mounting shaft 103 rotatably connected to the lower end of the cover plate 102, a handle is fixed to the upper end of the cover plate 102, a C-shaped mounting plate 104 is fixed on the mounting shaft 103, a scale plate 105 is fixed on the C-shaped mounting plate 104, and a gap is left between the scale plate 105 and the C-shaped mounting plate 104; a suspension rope 106 is arranged at the lower end of the cover plate 102, a plumb bob 107 is fixed to the end of the suspension rope 106, and the suspension rope 106 is located between the scale plate 105 and the C-shaped mounting plate 104; a telescopic support mechanism 2 is arranged between the protective bottom shell 101 and the cover plate 102, and the telescopic support mechanism 2 drives the cover plate 102 to move away from or close to the protective bottom shell 101 by telescoping; a transmission mechanism 4 is arranged at the lower end of the cover plate 102, and when the cover plate 102 moves close to or away from the protective bottom shell 101, the transmission mechanism 4 drives the mounting shaft 103 to rotate.

[0031] In the embodiment of the present invention, during use, place the slope degree measuring device on the slope to be measured, then hold the handle and pull the sealing cover plate 102 upward. The telescopic support mechanism 2 extends. At this time, the sealing cover plate 102 moves away from the protective bottom shell 101. The sealing cover plate 102 drives the C-shaped mounting plate 104, the scale plate 105, the suspension rope 106 and the plumb bob 107 to disengage from the protective bottom shell 101, and then takes out the C-shaped mounting plate 104, the scale plate 105, the suspension rope 106 and the plumb bob 107 from the protective bottom shell 101. When the sealing cover plate 102 moves away from the protective bottom shell 101, the transmission mechanism 4 drives the mounting shaft 103 to rotate. The mounting shaft 103 drives the C-shaped mounting plate 104 and the scale plate 105 to rotate until the scale plate 105 is perpendicular to the sealing cover plate 102. The plumb bob 107 drives the suspension rope 106 to be straightened and vertically downward by its own weight, and reads the value through the coincidence position of the suspension rope 106 and the scale plate 105, so as to measure the slope degree. After use, push the sealing cover plate 102 downward. The telescopic support mechanism 2 contracts, and the sealing cover plate 102 moves closer to the protective bottom shell 101. When the sealing cover plate 102 moves closer to the protective bottom shell 101, the transmission mechanism 4 drives the mounting shaft 103 to reverse. The mounting shaft 103 drives the C-shaped mounting plate 104 and the scale plate 105 to reverse until the scale plate 105 is parallel to the sealing cover plate 102 and the scale plate 105 stops rotating. Subsequently, the sealing cover plate 102 covers the upper end of the protective bottom shell 101. At this time, the C-shaped mounting plate 104, the scale plate 105, the suspension rope 106 and the plumb bob 107 are stored in the protective bottom shell 101, thereby protecting the scale plate 105, the suspension rope 106 and the plumb bob 107. Compared with the existing assembled slope degree measuring device for water conservancy construction, which requires installing and disassembling the scale plate 105, the suspension rope 106 and the plumb bob 107 before and after use to protect them, the present invention can take out or put the scale plate 105, the suspension rope 106 and the plumb bob 107 into or out of the protective bottom shell 101 by opening and closing the sealing cover plate 102 on the protective bottom shell 101, and can automatically drive the scale plate 105 to rotate to the working state or the storage state without the need for cumbersome installation and disassembly of the scale plate 105, the suspension rope 106 and the plumb bob 107, so as to protect the scale plate 105, the suspension rope 106 and the plumb bob 107 when not in use, thus facilitating the use of the slope degree measuring device for water conservancy construction.

[0032] Such as Figure 1 , Figure 2 and Figure 4As shown, as a preferred embodiment of the present invention, the telescopic support mechanism 2 includes two first rotating shafts 201 rotatably connected to the side wall of the protective bottom shell 101, and a first connecting rod 202 and a first gear 206 fixed on each of the two first rotating shafts 201; the two first gears 206 are meshed with each other, and the ends of the two first connecting rods 202 are rotatably connected to a second connecting rod 203, and the middle parts of the two second connecting rods 203 are rotatably connected; the ends of the two second connecting rods 203 are rotatably connected to a third connecting rod 204, and the ends of the two third connecting rods 204 are fixed with a second rotating shaft 205, and the two second rotating shafts 205 are rotatably connected to the lower end of the cover plate 102; a protective side shell 207 is fixed on the side wall of the protective bottom shell 101, the first gear 206 is located in the protective side shell 207, a limiting component 3 is arranged on the cover plate 102, and the limiting component 3 is used for limiting the rotation of one of the second rotating shafts 205; the limiting component 3 includes a guide groove 301 vertically arranged in the cover plate 102, and a guide block 302 slidably connected in the guide groove 301; one end of the guide block 302 is fixed with a first compression spring 303 and a pull cap 304, the other end of the guide block 302 is fixed with a limiting rod 305, and two limiting sunk grooves 306 cooperating with the limiting rod 305 are arranged on one of the second rotating shafts 205.

[0033] In the embodiment of the present invention, during use, the pull cap 304 is pulled upward, thereby overcoming the elastic force of the first compression spring 303 and driving the guide block 302 to move upward. The guide block 302 drives the limit rod 305 to disengage from one of the limit sunk grooves 306. Then, the cover plate 102 is pulled upward and the pull cap 304 is released. Under the action of the two first gears 206, the two first connecting rods 202 rotate synchronously towards each other, thereby causing the two second connecting rods 203 to rotate synchronously. The two second connecting rods 203 drive the two third connecting rods 204 to rotate synchronously in the opposite direction. The two third connecting rods 204 drive the two second rotating shafts 205 to rotate synchronously in the opposite direction, thereby guiding the movement of the cover plate 102 until the first compression spring 303 pushes the limit rod 305 into the other limit sunk groove 306, thereby locking the height of the cover plate 102; after use, the pull cap 304 is pulled upward, thereby overcoming the elastic force of the first compression spring 303 and driving the guide block 302 to move upward. The guide block 302 drives the limit rod 305 to disengage from the other limit sunk groove 306. Then, the cover plate 102 is pushed downward and the pull cap 304 is released. Under the action of the two first gears 206, the two first connecting rods 202 rotate synchronously in the opposite direction, thereby causing the two second connecting rods 203 to rotate synchronously in the opposite direction. The two second connecting rods 203 drive the two third connecting rods 204 to rotate synchronously. The two third connecting rods 204 drive the two second rotating shafts 205 to rotate synchronously in the opposite direction, thereby guiding the movement of the cover plate 102 until the first compression spring 303 pushes the limit rod 305 into one of the limit sunk grooves 306, thereby locking the height of the cover plate 102. At this time, the cover plate 102 covers the protective bottom shell 101.

[0034] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, as a preferred embodiment of the present invention, the transmission mechanism 4 includes a chute 401 horizontally arranged at the lower end of the cover plate 102, and a rack 402 slidably connected in the chute 401; a second gear 403 is fixed on another second rotating shaft 205, the second gear 403 meshes with the rack 402, one end of the mounting shaft 103 is provided with a rotating shaft 404 connected thereto, a third gear 405 is fixed on the rotating shaft 404, and the third gear 405 meshes with the rack 402. A torsion spring 501 is fixed on the rotating shaft 404, the end of the torsion spring 501 is fixed on the mounting shaft 103, an arc-shaped slider 503 is fixed at one end of the mounting shaft 103, a C-shaped groove 502 is provided at one end of the rotating shaft 404 close to the mounting shaft 103, and the arc-shaped slider 503 is slidably connected in the C-shaped groove 502.

[0035] In the embodiment of the present invention, when the sealing cover plate 102 is away from the protective bottom shell 101, the torsion spring 501 is in a twisted state. The second rotating shaft 205 drives the second gear 403 to rotate. Under the guiding action of the chute 401, the second gear 403 drives the rack 402 to move. The rack 402 drives the third gear 405 to rotate. The third gear 405 drives the rotating shaft 404 to rotate. When the rotating shaft 404 rotates, the arc-shaped slider 503 first moves in the C-shaped groove 502. At this time, the torsion spring 501 twists in the reverse direction to release energy until the arc-shaped slider 503 contacts one end of the C-shaped groove 502. The C-shaped groove 502 pushes the arc-shaped slider 503 to rotate. The arc-shaped slider 503 drives the mounting shaft 103 to rotate. Then, after the sealing cover plate 102 drives the mounting shaft 103, the C-shaped mounting plate 104, the scale plate 105, the suspension rope 106, and the plumb bob 107 to move upward and separate from the protective bottom shell 101, the mounting shaft 103 drives the C-shaped mounting plate 104 and the scale plate 105 to rotate downward, thereby providing space for the downward rotation of the C-shaped mounting plate 104 and the scale plate 105; after use, when it is necessary to store the mounting shaft 103, the C-shaped mounting plate 104, the scale plate 105, the suspension rope 106, and the plumb bob 107, the sealing cover plate 102 moves closer to the protective bottom shell 101, and the second rotating shaft 205 rotates in reverse. The second rotating shaft 205 drives the second gear 403 to rotate in reverse. Under the guiding action of the chute 401, the second gear 403 drives the rack 402 to move in the reverse direction. The rack 402 drives the third gear 405 to rotate in reverse. The third gear 405 drives the rotating shaft 404 to rotate in reverse. The rotating shaft 404 drives the mounting shaft 103 to rotate in reverse through the torsion spring 501. The mounting shaft 103 drives the C-shaped mounting plate 104 and the scale plate 105 to rotate upward until the C-shaped mounting plate 104 fits against the lower end of the sealing cover plate 102. At this time, the C-shaped mounting plate 104 and the scale plate 105 are in a stored state, and the C-shaped mounting plate 104 cannot continue to rotate relative to the sealing cover plate 102. The sealing cover plate 102 continues to drive the C-shaped mounting plate 104 and the scale plate 105 to move downward and enter the protective bottom shell 101. The rotating shaft 404 continues to rotate. The rotating shaft 404 overcomes the elastic force of the torsion spring 501 and drives the C-shaped groove 502 to rotate relative to the arc-shaped slider 503, thereby causing the arc-shaped slider 503 to move in the C-shaped groove 502. The rotating shaft 404 twists to store energy. Furthermore, through the settings of the torsion spring 501, the C-shaped groove 502, and the arc-shaped slider 503, while the rotating shaft 404 drives the mounting shaft 103 to rotate, relative rotation between the rotating shaft 404 and the mounting shaft 103 can also be achieved. Then, before the C-shaped mounting plate 104 and the scale plate 105 are received into the protective bottom shell 101, the C-shaped mounting plate 104 and the scale plate 105 can be in a horizontal stored state in advance, which is convenient for the storage of the C-shaped mounting plate 104 and the scale plate 105, and when the C-shaped mounting plate 104 and the scale plate 105 are used, after the C-shaped mounting plate 104 and the scale plate 105 separate from the protective bottom shell 101, the C-shaped mounting plate 104 and the scale plate 105 rotate downward, which is convenient for the storage and deployment of the C-shaped mounting plate 104 and the scale plate 105.

[0036] As Figures 1 - 10 shown, as a preferred embodiment of the present invention, a C-shaped chute 601 is provided on one side of the C-shaped mounting plate 104 close to the scale plate 105. A first sliding block 602 is slidably connected in the C-shaped chute 601. A through hole 603 is provided on the first sliding block 602. The suspension rope 106 passes through the through hole 603. A plurality of limiting holes 607 are evenly arranged in the C-shaped chute 601. A sliding groove 604 is provided in the first sliding block 602. A second sliding block 606 is slidably connected in the sliding groove 604. One end of the second sliding block 606 is fixed with a second compression spring 605 and a limiting shaft 608. The limiting shaft 608 cooperates with the limiting hole 607. A pushing assembly is provided on the first sliding block 602. The pushing assembly is used to drive the limiting shaft 608 to insert into the limiting hole 607. The pushing assembly includes a winding sleeve 701 fixed to the lower end of the cover plate 102. One end of the suspension rope 106 is fixed to the winding sleeve 701. A conical pushing surface 703 is provided on the plumb bob 107. A pushing block 702 is fixed to the other end of the second sliding block 606. The pushing block 702 cooperates with the conical pushing surface 703.

[0037] In the embodiment of the present invention, when the C-shaped mounting plate 104, the scale plate 105, the suspension rope 106 and the plumb bob 107 are stored, the cover plate 102 moves towards the protective bottom shell 101. The mounting shaft 103 drives the C-shaped mounting plate 104 and the scale plate 105 to rotate. The rotating C-shaped mounting plate 104 and scale plate 105 wind the suspension rope 106 on the winding sleeve 701. The length of the suspension rope 106 is reduced. The suspension rope 106 pulls the plumb bob 107 to move towards the first sliding block 602. The conical pushing surface 703 of the plumb bob 107 pushes the pushing block 702. Then, the second sliding block 606 overcomes the elastic force of the second compression spring 605 and drives the limiting shaft 608 to move. The limiting shaft 608 inserts into the limiting hole 607, thereby restricting the movement of the first sliding block 602, and further locking the position of the plumb bob 107, avoiding the shaking of the plumb bob 107 during storage, and avoiding the shaking plumb bob 107 hitting the scale plate 105 when carrying the slope measurement device for water conservancy construction, which is convenient for the storage of the slope measurement device for water conservancy construction.

[0038] The above embodiment of the present invention provides a slope measuring device for water conservancy construction. When in use, the slope measuring device is placed on the slope to be measured, and then the handle is held to pull the cover plate 102 upwards, and the pull cap 304 is pulled upwards, thereby overcoming the elastic force of the compression spring 303 and driving the guide block 302 to move upwards. The guide block 302 drives the limiting rod 305 to disengage from one of the limiting sinks 306, and then the cover plate 102 is pulled upwards and the pull cap 304 is released. Under the action of the two gears 206, the two connecting rods 202 The two connecting rods 203 rotate synchronously in opposite directions, and the two connecting rods 203 drive the two connecting rods 3 204 to rotate synchronously in the opposite direction, and the two connecting rods 3 204 drive the two rotating shafts 205 to rotate synchronously in the opposite direction, thereby guiding the movement of the cover plate 102, and the rotating shaft 205 drives the gear 2 403 to rotate. Under the guidance of the slide groove 401, the gear 2 403 drives the rack 402 to move, the rack 402 drives the gear 3 405 to rotate, and the gear 3 405 drives the rotating shaft 404 to rotate. When the rotating shaft 404 rotates, the arc-shaped slider 503 first moves in the C-shaped groove 502. At this time, the torsion spring 501 reverses and releases energy until the arc-shaped slider 503 contacts one end of the C-shaped groove 502. The C-shaped groove 502 pushes the arc-shaped slider 503 to rotate. The torsion spring 501 does not continue to reversely twist and release energy. The arc-shaped slider 503 drives the installation shaft 103 to rotate, and then the cover plate 102 drives the installation shaft 103, the C-shaped installation plate 104, the scale plate 105, the suspension rope 106 and the plumb bob 107 to move upward and separate from the protective bottom shell 101. Afterwards, the installation shaft 103 drives the C-shaped installation plate 104 and the scale plate 105 to rotate downward, thereby providing space for the C-shaped installation plate 104 and the scale plate 105 to rotate downward, until the scale plate 105 is perpendicular to the cover plate 102, and the compression spring 1 303 pushes the limit rod 305 to insert into another limit sink groove 306, thereby locking the height of the cover plate 102, and the plumb bob 107 drives the hanging rope 106 to be straightened and vertically downward by its own weight, and the reading is taken through the overlapping position of the hanging rope 106 and the scale plate 105, thereby measuring the slope degree;

[0039] After use, pull the pull cap 304 upward, thereby overcoming the elastic force of the first compression spring 303 and driving the guide block 302 to move upward. The guide block 302 drives the limit rod 305 to disengage from another limit sink 306, then push the sealing cover plate 102 downward and release the pull cap 304. Under the action of the two first gears 206, the two first connecting rods 202 rotate synchronously in the opposite direction, thereby causing the two second connecting rods 203 to rotate synchronously in the opposite direction. The two second connecting rods 203 drive the two third connecting rods 204 to rotate synchronously. The two third connecting rods 204 drive the two second rotating shafts 205 to rotate synchronously in the opposite direction, thereby guiding the movement of the sealing cover plate 102. The second rotating shaft 205 rotates in reverse. The second rotating shaft 205 drives the second gear 403 to rotate in reverse. Under the guiding action of the chute 401, the second gear 403 drives the rack 402 to move in the reverse direction. The rack 402 drives the third gear 405 to rotate in reverse. The third gear 405 drives the rotating shaft 404 to rotate in reverse. The rotating shaft 404 drives the mounting shaft 103 to rotate in reverse through the torsion spring 501. The mounting shaft 103 drives the C-shaped mounting plate 104 and the scale plate 105 to rotate upward until the C-shaped mounting plate 104 fits against the lower end of the sealing cover plate 102. At this time, the C-shaped mounting plate 104 and the scale plate 105 are in the storage state, and the C-shaped mounting plate 104 cannot continue to rotate relative to the sealing cover plate 102. The sealing cover plate 102 continues to drive the C-shaped mounting plate 104 and the scale plate 105 to move downward and enter the protective bottom shell 101. The rotating shaft 404 continues to rotate. The rotating shaft 404 overcomes the elastic force of the torsion spring 501 and drives the C-shaped groove 502 to rotate relative to the arc-shaped slider 503, thereby causing the arc-shaped slider 503 to move within the C-shaped groove 502. The rotating shaft 404 twists and stores energy until the C-shaped mounting plate 104 and the scale plate 105 enter the protective bottom shell 101. The first compression spring 303 pushes the limit rod 305 into one of the limit sinks 306, thereby locking the height of the sealing cover plate 102. At this time, the sealing cover plate 102 covers the protective bottom shell 101, thereby protecting the scale plate 105, the suspension rope 106, and the plumb bob 107. Compared with the existing assembled slope measurement device for water conservancy construction, which requires the installation and disassembly of the scale plate 105, the suspension rope 106, and the plumb bob 107 before and after use to protect the scale plate 105, the suspension rope 106, and the plumb bob 107, the present invention can take out or put the scale plate 105, the suspension rope 106, and the plumb bob 107 from or into the protective bottom shell 101 by opening and closing the sealing cover plate 102 on the protective bottom shell 101, and can automatically drive the scale plate 105 to rotate to the working state or the storage state without the need for cumbersome installation and disassembly of the scale plate 105, the suspension rope 106, and the plumb bob 107, so as to protect the scale plate 105, the suspension rope 106, and the plumb bob 107 when not in use, thereby facilitating the use of the slope measurement device for water conservancy construction.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
