Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering monitoring technology, specifically to a slope detection device for foundation pit monitoring. Background Technology
[0002] A foundation pit is a temporary or permanent earthwork project excavated on the ground during building construction to build underground structures (such as basements, foundations, subway stations, etc.). A slope measuring instrument is an engineering instrument used to measure the inclination angle of slopes, foundation pits, or ground. The specific method of use is to attach the bottom of the slope measuring instrument to the surface of the foundation pit and operate the measuring instrument to detect the slope value of the foundation pit.
[0003] While existing slope measuring instruments can generally measure the slope of foundation pits, they have shortcomings. When the pit surface becomes wet or even muddy due to rain or other damp weather, the bottom of the instrument comes into contact with the pit surface, causing dirt and grime to adhere to it, which is difficult to clean. The dirt becomes even more difficult to remove once it dries. Furthermore, in situations requiring tight deadlines, such as on cloudy days or at night when light is insufficient, it is difficult for workers to see the scale on the instrument. Even when holding a lighting tool in one hand and the instrument in the other, it is inconvenient for workers to record slope measurement data, resulting in low efficiency. Therefore, we propose a slope measuring device for foundation pit monitoring. Utility Model Content
[0004] The purpose of this invention is to provide a slope detection device for foundation pit monitoring, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides a slope detection device for foundation pit monitoring, comprising a detection instrument body, a cleaning mechanism for cleaning the bottom of the detection instrument body is provided on the surface of the detection instrument body, and an illumination mechanism for providing a light source for the detection instrument body is provided on one side of the detection instrument body, wherein:
[0006] The cleaning mechanism includes two symmetrically distributed troughs. One side of each trough is fixedly connected to both ends of the detector body, and the bottom of the trough is flush with the bottom of the detector body. A slider is provided inside the trough. A connecting rod is fixedly connected to one side of the slider via an adjustment knob. A cleaning block for cleaning the bottom of the detector body is fixedly connected between the two connecting rods, and the cleaning block is trapezoidal in shape.
[0007] As a further improvement to this technical solution, a through hole is provided at the center of one side of the connecting rod, and the through hole is interlocked with the adjustment knob.
[0008] As a further improvement to this technical solution, a gripping block is fixedly connected to one end of one side of the connecting rod.

[0010] As a further improvement to this technical solution, a groove is provided at the center of one side of the detector body, and the light-emitting surface of the lighting lamp is engaged with the groove.
[0011] As a further improvement to this technical solution, a short shaft is fixedly connected to one end of one side of the detector body, and a limit block is rotatably connected to the surface of the short shaft, with one side of the limit block in contact with the backlight surface of the lighting lamp.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] In this slope detection device for foundation pit monitoring, the setup includes a trough, a slider, a connecting rod, and a cleaning block. By rotating the adjustment knob to disengage it from the slider, and then rotating the connecting rod to bring the cleaning block flush with the bottom surface of the detector body, the adjustment knob is then rotated in the opposite direction to tighten it back inside the slider, limiting the connection rod and the cleaning block.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4 As shown, this embodiment provides a slope detection device for foundation pit monitoring, including a detector body 1. The detector body 1 includes a frame, a knob, a built-in gear system, a scale, and a bubble tube. The bubble tube is connected to a pointer. The bottom of the frame is placed against the surface of the foundation pit. Rotating the knob drives the built-in gear system, which in turn rotates the bubble tube, causing the bubble in the bubble tube to move to the middle position. Observing the position of the pointer on the scale allows the slope of the foundation pit to be detected. A cleaning mechanism 2 for cleaning the bottom of the detector body 1 is provided on the surface of the detector body 1. An illumination mechanism 3 for providing a light source to the detector body 1 is provided on one side of the detector body 1.
[0024] The cleaning mechanism 2 includes two symmetrically distributed troughs 21. One side of each trough 21 is fixedly connected to both ends of the detector body 1, and the bottom of each trough 21 is flush with the bottom of the detector body 1. A slider 22 is installed inside each trough 21. One side of each slider 22 is fixedly connected to a connecting rod 24 via an adjusting knob 23. A cleaning block 25 for cleaning the bottom of the detector body 1 is fixedly connected between the two connecting rods 24. The cleaning block 25 is made of polyurethane to enhance wear resistance, and its shape is trapezoidal. The trapezoidal shape allows the inclined surface of the cleaning block 25 to contact the bottom of the detector body 1, enabling better scooping of dirt and targeted cleaning of grime.
[0025] This utility model is as follows Figure 1-2 As shown, considering that the surface of the foundation pit becomes wet or even muddy due to rain or other humid weather, the bottom of the detector body 1 is attached to the bottom of the foundation pit, causing the bottom of the detector body 1 to be covered with mud and other dirt, which is difficult to clean. The mud becomes even more difficult to remove after it dries. Therefore, as Figure 2 and Figure 4 As shown, by setting up the tank 21, slider 22, connecting rod 24 and cleaning block 25, rotating the adjustment knob 23 disengages it from the slider 22, then rotating the connecting rod 24 drives the cleaning block 22 to be flush with the bottom surface of the detector body 1, then rotating the adjustment knob 23 in the opposite direction tightens it inside the slider 22 again, limiting the connecting rod 24 and the cleaning block 25, then sliding the slider 22 causes the cleaning block 25 to slide back and forth along the tank 21, thus cleaning the dirt and other grime at the bottom of the detector body 1 and preventing dirt and other grime from affecting the test results;
[0026] Considering that due to tight deadlines, it may be necessary to test the slope of deep foundation pits on cloudy days or at night when lighting is insufficient, workers may have difficulty seeing the scale on the measuring instrument body 1. Even if they hold a lighting tool in one hand and the measuring instrument body 1 in the other, it is inconvenient for workers to record slope measurement data, resulting in low testing efficiency. Therefore, if... Figure 2 As shown, by setting up the lighting mechanism 3, rotating the lighting mechanism 3 will make the light-emitting surface of the lighting mechanism 3 aligned with the scale on the detector body 1, providing light to the detector body 1. Even in the case of insufficient light, the staff can normally detect the slope data of the foundation pit, and it is convenient for the staff to record the slope data in a timely manner, thus improving the detection efficiency.
[0027] Based on the above, the specific structure will be disclosed in detail:
[0028] To ensure that the cleaning block 25 does not interfere with the contact between the bottom of the detector body 1 and the surface of the foundation pit when it is not in use, the specific structure of the cleaning mechanism 2 must be further disclosed. Therefore, as Figure 2 As shown, a through hole is provided at the center of one side of the connecting rod 24, and the through hole is fitted with the adjusting knob 23. Through the through hole, the adjusting knob 23 can pass through, allowing the connecting rod 24 to slide within a certain range to change the position of the cleaning block 25. The adjusting knob 23 is then used to fix the connecting rod 24 and the cleaning block 25. Figure 1 As shown, this ensures that the cleaning block 25 and the connecting rod 24 do not obstruct the bottom of the detector body 1 from contacting the pit surface when not in use.
[0029] To enable the connecting rod 24 and the cleaning block 25 to slide relatively easily along the groove 21, the specific structure of the cleaning mechanism 2 needs to be further disclosed. Therefore, as... Figure 2 As shown, a gripping block 26 is fixedly connected to one end of the connecting rod 24. By setting the gripping block 26, the staff can hold the gripping block 26 by hand and move it, which will drive the cleaning block 25 to move along the bottom of the detector body 1, scraping off the dirt and other grime on the bottom of the detector body 1, thus completing the cleaning work of the detector body 1.
[0030] To enable the lighting mechanism 3 to provide a light source for the detector body 1 in the event of insufficient light, the specific structure of the lighting mechanism 3 must be disclosed. Therefore, as shown below... Figure 2 As shown, the lighting mechanism 3 includes a fixed shaft 31, one end of which is fixedly connected to one end of the detector body 1. An illumination lamp 32 is rotatably connected to the surface of the fixed shaft 31. The illumination lamp 32 is powered by a built-in battery or USB. When the light-emitting surface of the illumination lamp 32 is aligned with the scale of the detector body 1, the illumination lamp 32 is activated to emit light, thus providing illumination for the staff and avoiding interference with the detection process.
[0031] In order to ensure that the illumination lamp 32 does not affect the use of the detector body 1 when it is not needed, and to provide a certain degree of protection for the illumination lamp 32, the structure of the detector body 1 must continue to be disclosed. Therefore, as Figure 2 As shown, a groove is provided in the center of one side of the detector body 1. The light-emitting surface of the lamp 32 is engaged with the groove. The groove allows the lamp 32 to be locked in when not in use, preventing it from affecting the continuation of the detection process and also providing some protection for the lamp 32.
[0032] To ensure that the lighting lamp 32 can be securely held in the groove, the specific structure of the detector body 1 needs to be further disclosed. Therefore, as... Figure 1 As shown, a short shaft is fixedly connected to one end of the detector body 1. A limit block 4 is rotatably connected to the surface of the short shaft. One side of the limit block 4 contacts the backlight surface of the lighting lamp 32. Through the setting of the limit block 4 and the short shaft, the lighting lamp 32 is stuck in the groove. The limit block 4 rotates around the short shaft as the axis. The limit block 4 rotates to the surface of the lighting lamp 32, which plays a certain limiting role for the lighting lamp 32.
[0033] To ensure smoother sliding of the slider 22 along the inner wall of the groove 1 without obstruction, the specific structure of the cleaning mechanism 2 needs to be further disclosed. Therefore, as... Figure 3 As shown, two mounting slots are respectively opened at the top and bottom of the slider 22, and rollers 27 are rotatably connected to both mounting slots. The surfaces of the two rollers 27 are in contact with the surfaces of the two slot bodies 21, respectively. The surfaces of the rollers 27 are provided with anti-fouling textures, and the inner walls of the slot bodies 21 are coated with a lubricating coating to prevent the rollers 27 from clogging. With the setting of the rollers 27, when the slider 22 slides along the inside of the slot body 21, the surfaces of the two rollers 27 are in contact with the inner walls of the slot body 21. The rollers 27 rotate continuously, reducing the friction between the slider 22 and the slot body 21, minimizing the possibility of the slider 22 clogging. In addition, the cleaning block 25 and the rollers 27 work together to improve the cleaning efficiency.
[0034] The specific working principle is as follows:
[0035] When cleaning block 25 is needed to clean dirt and grime from the bottom of the detector body 1, rotate adjustment knob 23 to disengage it from slider 22, rotate connecting rod 24 to bring the side of cleaning block 25 flush with the bottom of detector body 1, then rotate adjustment knob 23 in the opposite direction to tighten it back inside slider 22, limiting the connection rod 24 and cleaning block 25. The operator can then hold and move block 26 to move cleaning block 25 along the bottom of detector body 1, scraping off dirt and grime. When cleaning block 25 is no longer needed, rotate adjustment knob 23 again to disengage it from slider 22, rotate connecting rod 24 and cleaning block 25 so that they do not obstruct the bottom of detector body 1 from contacting the pit surface when not in use, then tighten adjustment knob 23.
[0036] When it is necessary to use the lighting lamp 32 to provide light for the staff, rotate the limiting block 4 so that the limiting block 4 is removed from the surface of the lighting lamp 32. Then, pull the lighting lamp 32 out of the groove and rotate the lighting lamp 32 so that the light-emitting surface of the lighting lamp 32 is aligned with the scale of the detector body 1 to provide light for the staff.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
