[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention

[0037] Please refer to Figures 1 to 12 , a land slope measuring device provided by an embodiment of the present invention, the land slope measuring device includes a slope placing cylinder 1, a measuring column 2, a slope measuring component 3 and a slope modifying component 5

[0038] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 , a bearing frame 11 is fixedly installed on the side cylinder wall of the slope placing cylinder 1, and an installation hole is provided on the bearing frame 11. The slope placing cylinder 1 is placed on the land slope surface through the bearing frame 11 and is arranged parallel to the land slope surface, and a bubble level 9 is built in the slope placing cylinder 1

[0039] It should be noted that: the slope placing cylinder 1 is placed on the continuous measured land slope surface through the bearing frame 11 on the slope placing cylinder 1, and is fixed on the soil slope by driving a ground nail through the installation hole provided on the bearing frame 11. At the same time, the slope placing cylinder 1 is adjusted so that the water bubble of the bubble level 9 is centered, causing the slope placing cylinder 1 to be fixed on the land slope surface and arranged parallel to the land slope surface, thereby completing the installation of the slope placing cylinder 1 on the land slope surface

[0040] In an embodiment of the present invention, please refer to Figure 1 , Figure 9 , Figure 10 and Figure 11 , a rotating connection measuring column 2 is installed on the slope setting cylinder 1, and the measuring column 2 can be received into the placement cavity 1a opened in the slope setting cylinder 1 by rotation. Specifically, a driving and resetting member 7 for driving the measuring column 2 to rotate out of the placement cavity 1a is installed on the slope setting cylinder 1. The driving and resetting member 7 includes side plates 71. There are two side plates 71 which are symmetrically distributed on both sides of the slope setting cylinder 1. At both ends of the upper surface of the side plate 71, a fixing block 72 and a voice player 76 are respectively and fixedly installed. A sliding rod 73 is fixedly installed on the fixing block 72, and a rack 74 which is slidably connected is sleeved on the sliding rod 73. A spring 75 with a compression structure is sleeved on the sliding rod 73. One end of the spring 75 is fixedly connected to the inner side wall of the fixing block 72, and the other end of the spring 75 is fixedly connected to one end of the rack 74. The driving and resetting member 7 further includes a connecting shaft 77. The connecting shaft 77 is rotatably installed at the tail side of the placement cavity 1a opened in the slope setting cylinder 1 and respectively penetrates out of the slope setting cylinder 1. Gears 78 are fixedly installed at both ends of the connecting shaft 77. The gears 78 are meshed with the corresponding racks 74. A rotating plate 21 is fixedly embedded at the bottom of the measuring column 2, and the rotating plate 21 is inserted into the tail side of the placement cavity 1a and fixedly connected to the connecting shaft 77;

[0041] A contact rod 741 is fixedly installed at one end of the rack 74 away from the spring 75, and the contact rod 741 corresponds to a touch switch 761 installed on the voice player 76. A threaded through hole is opened on the side plate 71 near the tail side, and a fixing screw 79 which is threadedly connected is inserted into the threaded through hole. A locking hole is opened on the outer side wall of the rack 74, and when the measuring column 2 rotates into the placement cavity 1a and is horizontally placed, the locking hole corresponds to the fixing screw 79.

[0042] It should be noted that when storing the measuring column 2, the measuring column 2 is rotated into the placement cavity 1a opened in the slope setting cylinder 1. At this time, the gear 78 on the connecting shaft 77 rotates and drives the rack 74 to slide along the sliding rod 73 towards the fixing block 72. Further, the spring 75 is compressed. When the measuring column 2 completely slides into the placement cavity 1a, the locking hole opened on the outer side wall of the rack 74 corresponds to the fixing screw 79. By rotating the fixing screw 79, the fixing screw 79 is driven to be inserted into the locking hole, so as to complete the storage of the measuring column 2 in the slope setting cylinder 1, greatly reducing the volume of the device and making it easy for the measuring personnel to take and carry;

[0043] When measuring the land slope, the slope setting cylinder 1 is pre-installed on the land slope. After completion, the fixing screw 79 is screwed out from the locking hole. At this time, under the elastic force of the compression spring 75, the rack 74 slides along the sliding rod 73 towards the voice player 76. Thus, the rack 74 drives the measuring column 2 to slide out of the placement cavity 1a opened in the slope setting cylinder 1 through the gear 78 until the abutting rod 741 on the rack 74 abuts against the touch switch 761 on the voice player 76 and then the rack 74 stops sliding, and the measuring column 2 rotates to a state perpendicular to the slope setting cylinder 1. At the same time, the voice player 76 is turned on and plays the voice indicating that the rotation of the measuring column 2 is completed. Therefore, the measuring column 2 can quickly form a state perpendicular to the slope setting cylinder 1, and there is no need for manual confirmation of the angle of the measuring column 2 again, improving the efficiency of land slope measurement.

[0044] Further, after the measuring column 2 quickly forms a state perpendicular to the slope setting cylinder 1, the fixing screw 79 is tightened again so that the fixing screw 79 presses against the corresponding side wall of the rack 74. Therefore, the measuring column 2 can stably maintain a perpendicular state to the slope setting cylinder 1.

[0045] It should be noted that: in order to improve the stability of the measuring column 2 when it slides out of the slope setting cylinder 1, when the fixing screw 79 is loosened, the measuring column 2 is held by hand and driven to slowly rotate to a state perpendicular to the slope setting cylinder 1.

[0046] In this solution, an indicator light can also be provided on the voice player 76, so that the measuring personnel can also know whether the measuring column 2 is perpendicularly arranged with the slope setting cylinder 1 according to the indicator light.

[0047] In the embodiment of the present invention, please refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8 , an installation cavity 2a is opened on the measuring column 2, and a slope measuring component 3 is installed in the installation cavity 2a. The slope measuring component 3 includes a transparent cylinder 31. Rotating columns 32 and counterweight columns 33 are respectively fixedly fitted at the upper and lower ends of the transparent cylinder 31. And the rotating column 32 is rotatably installed in the installation cavity 2a through a rotating shaft. A scale disk 34 is fixedly installed at the top of the rotating column 32, and a vertically upward pointer A35 is fixedly installed on the scale disk 34. And an arc-shaped scale 4 for displaying the slope is fixedly installed on the inner top wall of the installation cavity 2a.

[0048] It should be noted that: when the measuring column 2 is in a state perpendicular to the slope setting cylinder 1, at this time, the rotating column 32 deflects in the installation cavity 2a under the gravity of the counterweight column 33 and the silicone oil 8 in the transparent cylinder 31 and forms a freely hanging state (as shown in the attachment Figure 12 ), and the pointer A35 deflects accordingly and points to the corresponding scale on the arc-shaped scale 4, and the slope of the slope can be quickly determined;

[0049] Since the counterweight column 33 and the silicone oil 8 in the transparent cylinder 31 form a heavy cylinder structure, it is possible to reduce the risk that the counterweight column 33 rotates randomly due to wind vibration during field measurement, which may cause unstable measurement.

[0050] In an embodiment of the present invention, please refer to Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 . A slope correction component 5 is further installed on the rotating column 32. The accuracy of slope measurement is enhanced through the slope correction component 5. The slope correction component 5 includes a ceramic shaft 51. A collar 52 and a pointer B55 are fixedly sleeved on the ceramic shaft 51. Specifically, one shaft column of the ceramic shaft 51 is rotatably installed in a rotating cavity 32a formed in the rotating column 32, and the other shaft column of the ceramic shaft 51 is inserted into an indicating cavity 32b formed in the rotating column 32 and is rotatably connected to the side wall of the indicating cavity 32b. The collar 52 is fixedly sleeved on the shaft column in the rotating cavity 32a, and the pointer B55 is fixedly sleeved on the shaft column of the indicating cavity 32b and extends out of the rotating column 32 from the top of the indicating cavity 32b. The pointer B55 is located on the front side of the scale disk 34. A suspension rod 53 coaxially arranged with the transparent cylinder 31 and extending into the transparent cylinder 31 is fixedly installed on the lower ring surface of the collar 52. A counterweight ball 54 is fixedly installed on the suspension rod 53. The transparent cylinder 31 is filled with a sufficient amount of silicone oil 8.

[0051] It should be noted that: while the measuring column 2 is perpendicular to the slope setting cylinder 1, the counterweight ball 54 at the bottom of the suspension rod 53 swings in a drooping state in the transparent cylinder 31 due to its own gravity, thus driving the ceramic shaft 51 to rotate slightly, and then the pointer B55 deflects synchronously. The scale value pointed to by the pointer B55 on the scale disk 34 is the difference in the slope measured by the slope measuring component 3 (as shown in Figure 12 ). If there is no difference or the difference is within the set range, the measurement data can be recorded. If the difference is too large, it indicates that there is a problem with the equipment and it needs to be repaired;

[0052] In this solution, the slope measuring component 3 and the slope correction component 5 form a double-scale slope measurement, which greatly improves the accuracy of the measurement data. Moreover, a self-checking system can be formed between the slope measuring component 3 and the slope correction component 5 to eliminate the problem that the measurement is incorrect because the detection personnel are unaware of equipment damage.

[0053] Among them, the silicone oil 8 filled in the transparent cylinder 31 can reduce the shaking of the counterweight ball 54 and also suppress wind vibration during field measurement or the shaking of the transparent cylinder 31, thereby improving the stability of the counterweight ball 54 during field stability measurement.

[0054] Further, the rotation cavity 32a communicates with the transparent cylinder 31. A sealing ring is sleeved on the shaft column between the rotation cavity 32a and the indicating cavity 32b where the ceramic shaft 51 is located, and is sealed with an O-ring or a silicone gasket to prevent the leakage or contamination of silicone oil. The indicating cavity 32b has an upwardly expanding structure to avoid limiting the deflection angle of the pointer B55.

[0055] Further, a threaded interface 22 is provided at the top of the measuring column 2, and a column cap 6 is sleeved on the threaded interface 22 and is threadedly connected. When storing the slope measuring component 3, the transparent cylinder is completely screwed into the installation cavity 2a and kept coaxial with the measuring column 2. Subsequently, the column cap 6 is threadedly installed on the threaded interface 22 to cover the slope measuring component 3 in the installation cavity 2a, effectively protecting the slope measuring component 3 and the leveling component 5 in the slope measuring component 3.

[0056] This application realizes passive measurement through a mechanical structure, avoiding the failure problem of electronic measurement devices in extreme environments (in this solution, if the voice player 76 fails, it does not affect the limitation of the side slip of the rack 74). At the same time, it takes into account both accuracy and portability. If further intelligence is required, an interface can be reserved to expand electronic sensors (such as transmitting slope data to a mobile phone APP via Bluetooth).

[0057] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present invention.
