Description

Technical Field

[0001] This application relates to the field of geological exploration, and particularly to a borehole water level measuring device for engineering geological exploration. Background Art

[0002] The borehole water level measuring device is used to monitor the change of the groundwater level to ensure the accuracy of engineering geological exploration and groundwater management.

[0003] Currently, there is a Chinese patent with the publication number: CN212903436U. This utility model discloses an automatic measuring device for the water level of a borehole in engineering geological exploration, including a detection rope. A floating block is fixedly connected to the lower end of the detection rope, a weight block is fixedly connected to the lower end of the floating block, two groups of second electrode blocks are fixedly connected to the lower end of the weight block, an insulating baffle is arranged between the two groups of second electrode blocks, and the insulating baffle is fixedly connected to the weight block and the two groups of second electrode blocks. One end of the floating block is fixedly connected with two groups of first electrode blocks, and the two groups of first electrode blocks are symmetric about the center of the floating block. In this utility model, by setting the second electrode block and the second alarm lamp, when the second electrode block contacts the water surface, the two groups of second electrode blocks can be connected, so that the second alarm lamp lights up, reminding the staff to prepare to measure the water level height. At the same time, the control panel reduces the motor speed to prevent the weight block from sinking too deep due to inertia when the first electrode block is submerged, resulting in inaccurate measurement.

[0004] Although the above solution has the above advantages, the disadvantage of the above solution is that when using the measuring device to measure the water level of the borehole, the probe on the cable is placed inside the borehole to measure the water level. After the measurement is completed, there will be a lot of soil on the surface of the cable. At this time, it is necessary to manually clean the soil on its surface, which is rather troublesome and reduces the practicability of the device. Moreover, during the measurement, sometimes due to the uneven ground of the support device, the cable is inclined, and at this time, the probe is not vertically placed in the borehole, which will affect the accuracy of the measurement data. Summary of the Utility Model

[0005] The borehole water level measuring device for engineering geological exploration provided by this application does not require manual cleaning of the cable after the detection, improving the practicability of the device. At the same time, this device can ensure that the probe is vertically placed in the borehole by adjusting the support height, reducing the measurement error caused by the inclination of the cable and improving the accuracy of the measurement data.

[0006] In order to achieve the above purpose, this application adopts the following technical solution: A borehole water level measuring device for engineering geological exploration, the device includes:

[0007] Two brackets;

[0008] The first connecting plate is fixedly arranged on one side of one of the brackets, and a first pressing plate is fixedly arranged on one side of the first connecting plate. The first pressing plate is connected to one of the brackets through the first connecting plate;

[0009] Two cross bars are fixedly arranged on one side of the first pressing plate, and a second pressing plate is movably sleeved on the outer surfaces of the two cross bars. The second pressing plate can slide on the outer surfaces of the two cross bars;

[0010] Two cones are respectively fixedly arranged on the opposite sides of the first pressing plate and the second pressing plate, and cleaning sponges are arranged on the outer surfaces of the two baffles. The materials of the two cleaning sponges are soft. By inserting the two cleaning sponges onto the outer surfaces of the two cones, the replacement of the two cleaning sponges is convenient;

[0011] A baffle is fixedly arranged at one end of the two cross bars. The baffle limits the movement of the second pressing plate to prevent it from sliding out;

[0012] A pulling plate is fixedly arranged on the side of the second pressing plate close to the baffle, and a positioning plate is movably embedded on one side of the pulling plate. The pulling plate facilitates the pulling of the second pressing plate, and the positioning plate limits the position of the pulling plate.

[0013] As a further improvement of the present application: Springs are movably sleeved on the outer surfaces of the two cross bars, and one sides of the two springs are respectively fixedly arranged on one side of the baffle. The elastic forces generated by the two springs push the second pressing plate to move towards the first pressing plate.

[0014] As a further improvement of the present application: Cable reels are arranged on the opposite sides of the two brackets, and cables are wound around the outer surfaces of the cable reels. The cables are wound by rotating the cable reels.

[0015] As a further improvement of the present application: A probe is installed at one end of the cable, and a round plate is fixedly sleeved on the outer surface of the cable. The water level of the drill hole is detected by the probe, and the round plate limits the winding of the cable.

[0016] As a further improvement of the present application: Groove plates are fixedly arranged on one sides of the inner walls of the two brackets, racks are slidably arranged on the opposite sides of the two groove plates, gears are meshed on one sides of the two racks, the two racks can slide on the inner walls of the two groove plates respectively, and the two gears rotate when the two racks move.

[0017] As a further improvement of the present application: Rotating rods are fixedly embedded in the inner walls of the two gears, rotating rings are fixedly arranged on one sides of the two rotating rods, the two rotating rods are respectively connected to the inner walls of the two brackets through bearings, the two rotating rods can rotate because of the bearings, and the two rotating rings facilitate the rotation of the rotating rods.

[0018] As a further improvement of the present application: Limiting plates are fixedly arranged on both sides of the two racks, and supporting plates are fixedly arranged on one side of the two racks. The multiple limiting plates limit the movement of the racks to prevent the two racks from sliding out of the inside of the two brackets.

[0019] As a further improvement of the present application: A second connecting plate is fixedly arranged on one side of the two brackets, and a bubble level is fixedly arranged on one side of the second connecting plate. It is possible to observe whether the bubble on the bubble level is at the center of the scale line to determine whether the device is in a horizontal position.

[0020] Compared with the prior art, the advantages and positive effects of the present application are as follows.

[0021] 1. In the present application, after the measurement is completed, the second pressing plate can slide on the outer surfaces of the two cross bars. At this time, the positioning plate is removed from the pulling plate, and the position of the second pressing plate is not limited. The elastic forces generated by the two springs push the second pressing plate to move towards the first pressing plate. The two cleaning sponges are located on the outer surface of the cable. At this time, the second pressing plate is squeezed by the two springs, so that the two cleaning sponges are closely attached to the outer surface of the cable. At this time, the cable is wound up by rotating the wire reel, and the two cleaning sponges clean the soil on the outer surface of the cable. When the circular plate touches the bottom positions of the first pressing plate and the second pressing plate, the rotation of the wire reel is stopped. Therefore, after the detection is completed, there is no need to manually clean the cable, which improves the practicability of the device.

[0022] 2. In the present application, when measuring the water level of the borehole, the device is placed at the use location, and the entire device is supported by the two supporting plates. At this time, it is possible to observe whether the bubble on the bubble level is at the center of the scale line to determine whether the device is in a horizontal position. When the two swivel rings drive the rotating rods to rotate in different directions, the two gears drive the two racks to move up and down, further enabling the two supporting plates to be at different heights. When the bubble on the bubble level is on the left side, the left supporting plate is driven to move towards the ground by clockwise rotating the left swivel ring, and the rotation is stopped when the bubble on the bubble level is at the center of the scale line. When the bubble on the bubble level is on the right side, the right supporting plate is driven to move towards the ground by counterclockwise rotating the right swivel ring, and the rotation is stopped when the bubble on the bubble level is at the center of the scale line. The probe is placed inside the borehole for detection. Therefore, adjusting the support height can ensure that the probe is vertically placed in the borehole, reducing the measurement error caused by the inclination of the cable and improving the accuracy of the measurement data.

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of this application, the following further describes this application with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to fully understand this application. However, this application can also be implemented in other ways different from those described herein. Therefore, this application is not limited by the specific embodiments disclosed in the following specification.

[0032] Example 1, as Figures 1 to 6 shown, this application provides a borehole water level measuring device for engineering geological exploration, and the device includes:

[0033] Two brackets 1;

[0034] The first connecting plate 2 is fixedly arranged on one side of one of the brackets 1, and a first pressing plate 201 is fixedly arranged on one side of the first connecting plate 2. The first pressing plate 201 is connected to one of the brackets 1 through the first connecting plate 2.

[0035] Two crossbars 202 are fixedly arranged on one side of the first pressing plate 201, and a second pressing plate 203 is movably sleeved on the outer surfaces of the two crossbars 202. The second pressing plate 203 can slide on the outer surfaces of the two crossbars 202;

[0036] Two conical bodies 204 are respectively fixedly arranged on the opposite sides of the first pressing plate 201 and the second pressing plate 203, and cleaning sponges 205 are arranged on the outer surfaces of the two baffles 206. The materials of the two cleaning sponges 205 are soft. By inserting the two cleaning sponges 205 onto the outer surfaces of the two conical bodies 204, the replacement of the two cleaning sponges 205 is facilitated;

[0037] A baffle 206 is fixedly arranged at one end of the two crossbars 202. The baffle 206 limits the movement of the second pressing plate 203 to prevent it from sliding out;

[0038] A pulling plate 207 is fixedly arranged on the side of the second pressing plate 203 close to the baffle 206, and a positioning plate 208 is movably embedded on one side of the pulling plate 207. The pulling plate 207 facilitates the pulling of the second pressing plate 203, and the positioning plate 208 limits the position of the pulling plate 207.

[0039] As Figures 1 to 6 shown, springs 209 are movably sleeved on the outer surfaces of the two crossbars 202. One sides of the two springs 209 are respectively fixedly arranged on one side of the baffle 206. The elastic forces generated by the two springs 209 push the second pressing plate 203 to move towards the first pressing plate 201.

[0040] As Figures 1 to 6 shown, a wire reel 210 is arranged on the opposite sides of the two brackets 1. A cable 211 is wound around the outer surface of the wire reel 210. The cable 211 is wound by rotating the wire reel 210.

[0041] As Figures 1 to 6 shown, a probe 212 is installed at one end of the cable 211. A circular plate 213 is fixedly sleeved on the outer surface of the cable 211. The water level of the drill hole is detected by the probe 212, and the circular plate 213 limits the winding of the cable 211.

[0042] As Figures 1 to 6 shown, groove plates 3 are fixedly arranged on one sides of the inner walls of the two brackets 1. Rack bars 301 are slidably arranged on the opposite sides of the two groove plates 3. Gears 302 are meshed on one sides of the two rack bars 301. Level gauges 309 are arranged on one sides of the two brackets 1. The two rack bars 301 can respectively slide inside the two groove plates 3. When the two rack bars 301 move, they drive the two gears 302 to rotate. Whether the device is in a horizontal position can be judged by the two level gauges 309.

[0043] As Figures 1 to 6As shown, rotating rods 303 are fixedly embedded in the inner walls of the two gears 302. Rotating rings 306 are fixedly arranged on one side of the two rotating rods 303. The two rotating rods 303 are connected to the inner walls of the two brackets 1 through bearings. The two rotating rods 303 can rotate due to the bearings, and the two rotating rings 306 facilitate the rotation of the rotating rods 303.

[0044] As Figures 1 to 6 shown, limit plates 304 are fixedly arranged on both sides of the two racks 301. Support plates 305 are fixedly arranged on one side of the two racks 301. The multiple limit plates 304 limit the movement of the racks 301 to prevent the two racks 301 from sliding out of the inside of the two brackets 1. When used on a plane, the positions of the two support plates 305 do not need to be adjusted.

[0045] As Figures 1 to 6 shown, a second connecting plate 307 is fixedly arranged on one side of the two brackets 1. A bubble level 308 is fixedly arranged on one side of the second connecting plate 307. It is possible to observe whether the bubble on the bubble level 308 is at the center of the scale line to determine whether the device is in a horizontal position.

[0046] Working principle: When measuring the water level of a borehole, place the device at the usage location and support the entire device through two support plates 305. At this time, observe whether the bubble on the bubble level 308 is at the center of the scale line to determine whether the device is in a horizontal position. When the two swivel rings 306 drive the rotating rod 303 to rotate in different directions, the two gears 302 drive the two racks 301 to move up and down, further causing the two support plates 305 to be at different heights. When the bubble on the bubble level 308 is on the left side, rotate the left swivel ring 306 clockwise to drive the left support plate 305 to move towards the ground, and stop rotating when the bubble on the bubble level 308 is at the center of the scale line. When the bubble on the bubble level 308 is on the right side, rotate the right swivel ring 306 counterclockwise to drive the right support plate 305 to move towards the ground, and stop rotating when the bubble on the bubble level 308 is at the center of the scale line. Place the probe 212 inside the borehole for detection. Thus, adjusting the support height can ensure that the probe 212 is vertically placed in the borehole, reducing measurement errors caused by the inclination of the cable 211 and improving the accuracy of measurement data. After the measurement is completed, the second pressing plate 203 can slide on the outer surfaces of the two cross bars 202. At this time, remove the positioning plate 208 from the pull plate 207. The position of the second pressing plate 203 is not restricted. The elastic force generated by the two springs 209 pushes the second pressing plate 203 towards the first pressing plate 201. The two cleaning sponges 205 are located on the outer surface of the cable 211. At this time, the second pressing plate 203 is squeezed by the two springs 209, causing the two cleaning sponges 205 to closely adhere to the outer surface of the cable 211. At this time, by rotating the cable reel 210 to wind up the cable 211, the two cleaning sponges 205 clean the soil on the outer surface of the cable 211. When the circular plate 213 touches the bottom positions of the first pressing plate 201 and the second pressing plate 203, stop the rotation of the cable reel 210. Thus, after the detection is completed, there is no need to manually clean the cable 211, improving the practicability of the device. By pulling the pull plate 207, the distance between the two cleaning sponges 205 can be made to accommodate the passage of the circular plate 213. At this time, take out the probe 212 and the cable 211 from between the two cleaning sponges 205.

[0047] The above are only the preferred embodiments of the application, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
