Description

Technical Field

[0001] This utility model relates to the technical field of soil and water conservation engineering tools, specifically a positioning ruler for excavating fish-scale pits for soil erosion control. Background Technology

[0002] Soil erosion is a global environmental problem, especially in hilly and mountainous areas, where it seriously threatens the ecological environment and agricultural production. Fish-scale pits, as an effective soil and water conservation engineering measure, involve excavating semi-circular pits on the surface to slow water flow, promote rainwater infiltration, and encourage vegetation growth. They are widely used to control mild to moderate soil erosion. The layout of fish-scale pits must strictly adhere to parameters such as pit spacing, pit depth, and levelness to ensure their water retention and soil conservation functions.

[0003] However, in the existing technology, the excavation and positioning of fish scale pits mostly rely on manual experience or simple tools, resulting in low positioning accuracy and poor efficiency. During construction, workers usually determine the pit location by visual inspection or simple measurement, which leads to inconsistent pit distances and irregular pit shapes, affecting the overall treatment effect and making horizontal control difficult.

[0004] Therefore, a positioning ruler for excavating fish-scale pits for soil erosion control is proposed to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a positioning ruler for excavating fish-scale pits for soil erosion control. It has the advantages of high precision, high efficiency, easy operation, and strong adaptability, and solves the problems of low positioning accuracy, poor construction efficiency, inconsistent pit spacing, and difficulty in horizontal control in traditional fish-scale pit excavation.

[0007] (II) Technical Solution

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A positioning ruler for excavating fish-scale pits for soil erosion control includes a first base plate and a second base plate. A ball joint seat is fixedly connected to the top of both the first and second base plates. A ball joint rod is movably connected inside the ball joint seat. A sliding groove is formed on the outer side of each ball joint rod. A friction strip is embedded and fixedly connected to the sliding groove. An elastic component is fixedly connected to the outer side of the ball joint rod above the first and second base plates at the top. The bottom of the first and second base plates... Each ball joint is provided with conical protrusions arranged in a ring array. The outer side of each ball joint is fitted with an outer sleeve that is slidably connected to the slide groove. The outer side of each outer sleeve is rotatably connected to a movable ring. The outer side of each movable ring is threadedly connected to a swing arm. The outer side of each outer sleeve is provided with a limiting component that extends into it and abuts against the friction strip. The top of each outer sleeve is rotatably connected to a mounting base. The outer side of the mounting base above the first base plate and the second base plate is provided with the same steel wire. The outer side of the steel wire is fixedly connected to a level tube. The top of each mounting base is provided with a universal level.

[0009] The beneficial effects of this utility model are:

[0010] The positioning ruler for the fish-scale pit excavation in this soil erosion control project is based on the layout parameters of the fish-scale pit. A suitable swing arm and steel wire are selected, with the swing arm length matching the radius of the fish-scale pit and the steel wire maintaining the same horizontal distance from the pit. Two operators each hold an outer sleeve. The first operator positions the first base plate below the outer sleeve at the center of the initial pit location using the conical protrusion, and maintains the sleeve's vertical position by observing the universal level. The second operator moves the outer sleeve until the steel wire is taut, maintaining the sleeve's vertical position by observing the universal level, and simultaneously observing the steel wire and the outer level tube to ensure the steel wire is horizontal. The first operator presses the limiting component, causing the ball joint inside the outer sleeve to slide out under its own weight. The second base plate contacts the ground and is positioned at that point by the conical protrusion. At this time, the distance between the first and second base plates matches the radius of the fish-scale pit. The construction workers then move the swing arm and sprinkle lime powder on the ground according to the swing arm's range of motion to determine the excavation range of the fish-scale pit. Wooden stakes are driven in, and the height of the top of the stakes is made consistent with the swing arm to determine the height of the fish-scale pit. Then, the second operator stays in place while the first operator continues to move, and the next pit is positioned in the same way. This method has the advantages of high precision, high efficiency, ease of operation, and strong adaptability.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the elastic component includes a tension spring and a mounting plate. The top of the first base plate and the second base plate are each attached with tension springs arranged in a circular array. The outer side of the ball head rod is fixedly connected with a mounting plate that is attached to the tension spring below it.

[0013] The beneficial effect of adopting the above-mentioned further solution is that when the operator lowers the ball joint, the ball joint slides inside the outer sleeve under gravity to adapt to changes in ground height. After the first base plate or the second base plate contacts the ground, due to the movable connection between the ball joint seat and the lower end of the ball joint, the first base plate or the second base plate is in contact with the ground. At the same time, the tension spring undergoes elastic deformation, and the first base plate or the second base plate is positioned at this point through the conical protrusion. When the first base plate or the second base plate is retracted, the tension spring restores its deformation and thus drives the first base plate or the second base plate to return to its original position.

[0014] Furthermore, the limiting component includes a rectangular cover, an arc-shaped arm, a contact block, a spring, and a ball-head button. The outer side of the outer sleeve is fixedly connected to a rectangular cover that communicates with its interior. The interior of the rectangular cover is rotatably connected to an arc-shaped arm whose upper end extends into a sliding groove. The upper end of the arc-shaped arm is fixedly connected to a contact block that abuts against the friction strip. A spring is provided between the arc-shaped arm and the inner wall of the rectangular cover. The front side of the rectangular cover is slidably connected to a ball-head button that extends into the interior and abuts against the arc-shaped arm.

[0015] The beneficial effect of adopting the above-mentioned further solution is that pressing the ball head button drives the arc arm to separate the contact block from the friction strip, releasing the locking limit of the ball head rod. At the same time, the spring plate undergoes elastic deformation. When the ball head button is released, the spring plate returns to its deformation, which in turn pushes the arc arm to reset the contact block, so that the contact block abuts against the friction strip, thereby restoring the locking limit of the ball head rod.

[0016] Furthermore, both ends of the steel wire are fixedly connected with bolts that are threadedly connected to the mounting base.

[0017] The advantage of adopting the above-mentioned further solution is that the two ends of the steel wire are equipped with bolts that are compatible with the mounting base, so as to replace the appropriate steel wire according to the size of the horizontal pit distance of the fish scale pit.

A ball joint rod 3 is movably connected inside the ball joint seat 2. A sliding groove 4 is formed on the outer side of each ball joint rod 3. A friction strip 5 is embedded and fixedly connected inside each sliding groove 4. An elastic component 6 is fixedly connected to the outer side of the ball joint rod 3 above each of the first base plate 1 and the second base plate 1a. A ring-shaped array of [missing information] is distributed at the bottom of both the first base plate 1 and the second base plate 1a. The conical protrusion 7 and the ball head rod 3 are all fitted with an outer sleeve 8 that is slidably connected to the slide groove 4. The outer sleeve 8 is rotatably connected to a movable ring 9. The outer sleeve 9 is threadedly connected to a swing arm 10. The outer sleeve 8 is provided with a limiting component 11 that extends into its interior and abuts against the friction strip 5. The top of the outer sleeve 8 is rotatably connected to a mounting base 12. The mounting base 12 above the first base plate 1 and the second base plate 1a is provided with the same steel wire 13. The outer side of the steel wire 13 is fixedly connected to a level tube 14. The top of the mounting base 12 is provided with a universal level 15.

[0025] The elastic component 6 includes a tension spring 601 and a mounting plate 602. The top of the first base plate 1 and the second base plate 1a are each attached with tension springs 601 arranged in a ring array. The outer side of the ball head rod 3 is fixedly connected with a mounting plate 602 that is attached to the tension spring 601 below it.

[0026] The limiting component 11 includes a rectangular cover 111, an arc arm 112, a contact block 113, a spring piece 114, and a ball head button 115. The outer side of the outer sleeve 8 is fixedly connected to the rectangular cover 111, which communicates with the interior. The inner side of the rectangular cover 111 is rotatably connected to the arc arm 112, which extends into the slide groove 4. The upper end of the arc arm 112 is fixedly connected to the contact block 113, which abuts against the friction strip 5. A spring piece 114 is provided between the arc arm 112 and the inner wall of the rectangular cover 111. The front side of the rectangular cover 111 is slidably connected to the ball head button 115, which extends into the interior and abuts against the arc arm 112.

[0027] Both ends of the steel wire 13 are fixedly connected with bolts that are threaded to the mounting base 12.

[0028] Working principle:

[0029] Step 1: According to the layout parameters of the fish scale pit, select the appropriate swing arm 10 and steel wire 13. The length of the swing arm 10 is compatible with the radius of the fish scale pit, and the steel wire 13 is consistent with the horizontal pit distance of the fish scale pit. Tighten the swing arm 10 to the outside of the movable ring 9, and connect the steel wire 13 to the mounting base 12 by bolts at both ends.

[0030] Step 2: Two operators each hold the outer sleeve 8. The first operator positions the first base plate 1 below the outer sleeve 8 in his hand at the center of the starting pit through the conical protrusion 7, and keeps the outer sleeve 8 in a vertical position by observing the universal level 15.

[0031] Step 3: The second operator moves the outer sleeve 8 by holding it until the steel wire 13 is straightened. By observing the universal level 15, the outer sleeve 8 is kept vertical and kept in this position. At the same time, the operator observes the steel wire 13 and the level tube 14 on the outside to make the steel wire 13 horizontal. The second operator presses the ball head button 115, which drives the arc arm 112 to separate the contact block 113 from the friction strip 5, releasing the locking limit on the ball head rod 3. The ball head rod 3 inside the outer sleeve 8 slides out by its own weight to adapt to changes in ground height. After the second base plate 1a contacts the ground, the second base plate 1a is in contact with the ground because the ball head joint seat 2 is movably connected to the lower end of the ball head rod 3. At the same time, the tension spring 601 undergoes elastic deformation. The second base plate 1a is positioned at this point by the conical protrusion 7. At this time, the distance between the first base plate 1 and the second base plate 1a is adapted to the radius of the fish scale pit.

[0032] Step 4: The construction workers use the swing arm 10 to spread lime powder on the ground according to the range of motion of the swing arm 10 to determine the excavation range of the fish scale pit. They then drive wooden stakes into the ground, ensuring that the height of the top of the stakes is consistent with that of the swing arm 10, thus determining the height of the fish scale pit. Then, the second operator remains stationary while the first operator continues to move forward, and the next pit is located in the same manner.
