DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 12 An embodiment of the present invention provides a land slope measuring device, which includes a slope setting cylinder 1, a measuring column 2, a slope measuring component 3 and a slope repair component 5.

[0021] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A support frame 11 is fixedly mounted on the side wall of the slope setting cylinder 1, and a mounting hole is opened on the support frame 11. The slope setting cylinder 1 is placed on the land slope surface through the support frame 11 and is arranged parallel to the land slope surface, and a bubble level 9 is built in the slope setting cylinder 1.

[0022] It should be noted that: the support frame 11 on the slope setting tube 1 is placed on the land slope to be measured, and the support frame 11 is fixed to the land slope by means of ground nails passing through the mounting holes provided in the support frame 11. At the same time, the slope setting tube 1 is adjusted so that the bubble of the bubble level 9 is centered, so that the slope setting tube 1 is fixed on the land slope and arranged parallel to the land slope, thereby completing the installation of the slope setting tube 1 on the land slope.

[0023] In the embodiments of the present invention, please refer to Figure 1 , Fig. 9 , Fig.10 as well as Fig.11The slope setting cylinder 1 is provided with a rotatably connected measuring column 2, and the measuring column 2 can be received in the placement cavity 1a opened by the slope setting cylinder 1 by rotation. Specifically, the slope setting cylinder 1 is provided with a driving and resetting member 7 for driving the measuring column 2 to rotate to the placement cavity 1a, and the driving and resetting member 7 includes a side plate 71, and the side plate 71 is provided with two pieces and symmetrically distributed on both sides of the slope setting cylinder 1, and the two ends of the upper surface of the side plate 71 are respectively fixedly installed with a fixed block 72 and a voice player 76, and a sliding rod 73 is fixedly installed on the fixed block 72, and a sliding rack 74 is sleeved on the sliding rod 73. A spring 75 of a compression structure is provided, one end of the spring 75 is fixedly connected to the inner wall of the fixed block 72, and the other end of the spring 75 is fixedly connected to one end of the rack 74, and the driving reset member 7 also includes a connecting shaft 77, which is rotatably mounted on the tail side of the placement cavity 1a opened by the slope cylinder 1 and passes through the slope cylinder 1 respectively, and gears 78 are fixedly installed at both ends of the connecting shaft 77, and the gears 78 are meshed and connected with the corresponding racks 74, and 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; An abutment rod 741 is fixedly installed on one end of the rack 74 away from the spring 75, and the abutment rod 741 corresponds to the contact switch 761 installed on the voice player 76. A threaded through hole is opened on the plate surface of the side plate 71 near the tail side, and a threaded through hole is inserted into the threaded through hole and connected to the fixing screw 79. A locking hole is opened on the outer wall of the rack 74, and the locking hole corresponds to the fixing screw 79 when the measuring column 2 is rotated to be placed horizontally in the placement cavity 1a.

[0024] 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 tube 1, and the gear 78 on the connecting shaft 77 rotates and drives the rack 74 to slide along the sliding rod 73 toward the fixed block 72, and the spring 75 is further compressed. When the measuring column 2 completely slides into the placement cavity 1a, the locking hole opened on the outer wall of the rack 74 corresponds to the fixing screw 79, and the fixing screw 79 is driven to be inserted into the locking hole by rotating the fixing screw 79, thereby completing the storage of the measuring column 2 in the slope setting tube 1, which greatly reduces the volume of the device and makes it easy for the measurement personnel to take and carry it; When measuring the slope of the land, the slope cylinder 1 is installed on the slope of the land in advance. After completion, the fixing screw 79 is unscrewed 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 toward the voice player 76, so that the rack 74 drives the measuring column 2 to slide out of the placement cavity 1a opened in the slope cylinder 1 through the gear 78, until the abutment rod 741 on the rack 74 abuts with the contact 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 cylinder 1. At the same time, the voice player 76 starts and plays the voice of the measurement column 2 after the rotation is completed. Therefore, the measurement column 2 can quickly form a state perpendicular to the slope cylinder 1, and there is no need to manually confirm the angle of the measurement column 2 again, thereby improving the efficiency of land slope measurement.

[0025] Furthermore, after the measuring column 2 quickly forms a vertical state with the slope setting cylinder 1, the fixing screw 79 is tightened again so that the fixing screw 79 presses the corresponding side wall of the rack 74, so that the measuring column 2 can be stably maintained in a vertical state with the slope setting cylinder 1.

[0026] It is worth noting that in order to improve the stability of the measuring column 2 when it is rotated out of the slope setting cylinder 1, when loosening the fixing screw 79, hold the measuring column 2 by hand and drive the measuring column 2 to slowly rotate to a vertical state with the slope setting cylinder 1.

[0027] In this solution, an indicator light may also be provided on the voice player 76, so that the surveying personnel can also know whether the measuring column 2 is vertically arranged with the slope setting tube 1 according to the indicator light.

[0028] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 8 A mounting cavity 2a is provided on the measuring column 2, and a slope measuring component 3 is installed in the mounting cavity 2a. The slope measuring component 3 includes a transparent cylinder 31, and a rotating column 32 and a counterweight column 33 are fixedly engaged at the upper and lower ends of the transparent cylinder 31 respectively. The rotating column 32 is rotatably installed in the mounting cavity 2a through a rotating shaft. A dial 34 is fixedly installed on the top of the rotating column 32, and a vertically upward pointer A35 is fixedly installed on the dial 34. An arc scale 4 for displaying the slope is fixedly installed on the inner top wall of the mounting cavity 2a.

[0029] It should be noted that: when the measuring column 2 and the slope setting cylinder 1 are in a vertical state, the rotating column 32 is deflected in the installation cavity 2a and forms a free hanging state under the gravity of the counterweight column 33 and the silicone oil 8 in the transparent cylinder 31 (as shown in the attached figure). Fig.12 As shown), the pointer A35 deflects and points to the corresponding scale of the arc scale 4, and the slope of the slope can be quickly determined; Since the weight column 33 and the silicone oil 8 in the transparent tube 31 form a heavy cylinder structure, the risk of the weight column 33 rotating randomly due to wind vibration during field measurement, thereby causing unstable measurement, can be reduced.

[0030] In the embodiments of the present invention, please refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 A correction component 5 is also installed on the rotating column 32, and the accuracy of slope measurement is enhanced by the correction component 5. The correction component 5 includes a ceramic shaft 51, and a ring 52 and a pointer B55 are fixedly sleeved on the ceramic shaft 51. Specifically, one section of the ceramic shaft 51 is rotatably installed in the rotating cavity 32a opened by the rotating column 32, and the other section of the ceramic shaft 51 is inserted into the indicating cavity 32b opened by the rotating column 32 and is rotatably connected to the side wall of the indicating cavity 32b, the ring 52 is fixedly sleeved on the shaft in the rotating cavity 32a, the pointer B55 is fixedly sleeved on the shaft in the indicating cavity 32b and extends from the top of the rotating column 32b, and the pointer B55 is located on the front side of the dial 34, and the lower ring surface of the ring 52 is fixedly installed with a suspension rod 53 coaxially arranged with the transparent cylinder 31 and extending into the transparent cylinder 31, a counterweight ball 54 is fixedly installed on the suspension rod 53, and the transparent cylinder 31 is filled with a sufficient amount of silicone oil 8.

[0031] It should be noted that: while the measuring column 2 and the slope setting cylinder 1 are in a vertical state, the weighted ball 54 at the bottom of the suspension rod 53 is also drooping in the transparent cylinder 31 due to its own gravity, thereby driving the ceramic shaft 51 to rotate slightly, so that the pointer B55 is deflected synchronously, and the scale value of the dial 34 pointed by the pointer B55 is the difference in the slope measured by the slope measuring component 3 (as shown in the attached figure). Fig.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 means that there is a problem with the equipment and it needs to be repaired. In this solution, the slope measuring component 3 and the degree repair component 5 form a dual-scale slope measurement, which greatly improves the accuracy of the measurement data. In addition, a self-checking system can be formed between the slope measuring component 3 and the degree repair component 5 to eliminate the problem of measurement errors caused by the inspection personnel being unaware of equipment damage.

[0032] The silicone oil 8 filled in the transparent tube 31 can reduce the shaking of the weight ball 54 and can also suppress wind vibration or shaking of the transparent tube 31 during field measurement, thereby improving the stability of the weight ball 54 during field stability measurement.

[0033] Furthermore, the rotating chamber 32a is connected to the transparent tube 31, and the ceramic shaft 51 is arranged on the shaft column between the rotating chamber 32a and the indicating chamber 32b and is sleeved with a sealing ring. An O-ring or a silicone gasket is used for sealing to prevent silicone oil leakage or contamination. The indicating chamber 32b has an upward and outward expansion structure to avoid limiting the deflection angle of the pointer B55.

[0034] Furthermore, a threaded interface 22 is provided on the top of the measuring column 2, and a threaded column cap 6 is sleeved on the threaded interface 22. When the slope measuring component 3 is stored, the transparent tube is completely screwed into the installation cavity 2a and kept coaxial with the measuring column 2. Then, the column cap 6 is threadedly installed on the threaded interface 22 and the slope measuring component 3 in the installation cavity 2a is covered, thereby effectively protecting the slope measuring component 3 and the repair component 5 in the slope measuring component 3.

[0035] The present application realizes passive measurement through a mechanical structure, avoiding the failure problem of electronic measuring equipment in extreme environments (in this solution, if the voice player 76 fails, it will not affect the restriction on the side sliding of the rack 74), while taking into account both accuracy and portability. If further intelligence is required, an interface can be reserved to expand electronic sensors (such as Bluetooth transmission of slope data to a mobile phone APP), etc.

[0036] The above descriptions are only embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
