The two marking rings are respectively arranged on the measuring ropes on both sides of the fixed pulley. The purpose of the utility model is to provide a simple real-time well liquid level measurement device for deep foundation pit dewatering engineering, which can conveniently and simply measure the well liquid level during the construction of foundation pit dewatering engineering, and at the same time avoid a large amount of manpower consumption during manual measurement with a ruler.

[0004] However, the above-mentioned utility model still has certain defects. On the one hand, since the construction site ground is not flat, the above-mentioned utility model cannot adjust the horizontal placement of the liquid level measurement device at the construction site, which is easy to cause the center to shift and result in measurement errors. On the other hand, it requires manual visual observation of the water level line and cannot automatically monitor the water level line and give an alarm. Content of the Utility Model

[0005] In order to solve the technical problems that the above-mentioned comparative document still cannot adjust the horizontal placement of the liquid level measurement device at the construction site, which is easy to cause the center to shift and result in measurement errors, and on the other hand, it requires manual visual observation of the water level line and cannot automatically monitor the water level line and give an alarm, the utility model provides the following technical solutions:

[0006] The utility model relates to a simple real-time well liquid level measurement device for deep foundation pit dewatering engineering, including a support base and a support rod. There are multiple support rods, which are annularly and rotatably installed on the outside of the support base. A fixed pulley is rotatably installed in the middle of the bottom end of the support base. Two limit rope frames are fixedly installed at the bottom of the support base, and the two limit rope frames are symmetrically arranged on both sides of the fixed pulley. A buoyancy assembly and a monitoring assembly are arranged on the support base;

[0007] The buoyancy assembly includes a connecting rope and a rope clip. The connecting rope passes through two limiting rope frames and is hung on a fixed pulley. Floating balls and plumb bobs are respectively and fixedly installed at both ends of the connecting rope. There are two rope clips, both of which are fixedly clamped on the connecting rope.

[0008] The monitoring assembly includes a controller and an infrared rangefinder. The controller is fixedly installed at the top of the support base. There are two infrared rangefinders, which are respectively and fixedly installed at the bottoms of the two limiting rope frames. A wire is electrically connected between the infrared rangefinder and the controller.

[0009] As a preferred technical solution of the present invention, a rotating seat is rotatably installed at one end of the support rod away from the support base. A ground nail is fixedly installed at the bottom of the rotating seat, and barbs are integrally formed on the ground nail.

[0010] As a preferred technical solution of the present invention, both between the support rod and the support base and between the support rod and the rotating seat are positioned by bolts and nuts.

[0011] As a preferred technical solution of the present invention, the weight of the floating ball is heavier than that of the plumb bob.

[0012] As a preferred technical solution of the present invention, a reflective sheet is fixedly installed at the top of the rope clip, and the reflective sheet and the infrared rangefinder are on the same horizontal straight line.

[0013] As a preferred technical solution of the present invention, sound and light alarms are fixedly installed on all four end faces of the controller, and a gyroscope is fixedly installed on the top.

[0014] As a preferred technical solution of the present invention, the sound and light alarm adopts a two-color light design.

[0015] The beneficial effects achieved by the present invention are:

[0016] Build a support base at the opening of the deep foundation pit, rotate the adjusting rod to adjust the support height, and rotate the rotating seat to adjust the insertion angle and depth of the ground nail so that the support base remains horizontal on the uneven ground.

[0017] During the dewatering process of the deep foundation pit, when the buoyancy of the floating ball decreases, the plumb bob is driven to rise through the connecting rope. One side of the rope clip rises and the other side of the rope clip descends. The infrared rangefinder emits infrared rays, and the infrared rays emitted by the infrared rangefinder are reflected by the reflective sheet and received by the infrared rangefinder to obtain the distance. Then, the water level depth is obtained through control conversion. At the same time, when the water level crosses the warning line or the support base is not horizontally placed, a sound and light alarm can be issued, and a two-color light design is adopted for warning differentiation.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment: As Figures 1-4 shown, a simple real-time well pipe liquid level measuring device for a deep foundation pit dewatering project includes a support base 1 and a support rod 2. There are multiple support rods 2, which are annularly and rotatably installed outside the support base 1. A fixed pulley 101 is rotatably installed in the middle of the bottom end of the support base 1. Two limit rope brackets 102 are fixedly installed at the bottom of the support base 1, and the two limit rope brackets 102 are symmetrically arranged on both sides of the fixed pulley 101. A buoyancy assembly 3 and a monitoring assembly 4 are arranged on the support base 1;

[0026] The buoyancy assembly 3 includes a connecting rope 301 and a rope clip 302. The connecting rope 301 passes through two limiting rope frames 102 and is hung on the fixed pulley 101. Floating balls 303 and lead weights 304 are respectively and fixedly installed at both ends of the connecting rope 301. There are two rope clips 302, and both are fixedly clamped on the connecting rope 301. During use, during the deep foundation pit dewatering process, when the buoyancy of the floating ball 303 decreases, it drives the lead weight 304 to rise through the connecting rope 301. One of the rope clips 302 on one side rises and the rope clip 302 on the other side descends, and double measurement is carried out by measuring the distance with the infrared rangefinder 402;

[0027] The monitoring assembly 4 includes a controller 401 and an infrared rangefinder 402. The controller 401 is fixedly installed on the top of the support base 1. There are two infrared rangefinders 402, which are respectively and fixedly installed at the bottoms of the two limiting rope frames 102. A wire 403 is electrically connected between the infrared rangefinder 402 and the controller 401.

[0028] A rotating seat 201 is rotatably installed at one end of the support rod 2 away from the support base 1. A ground nail 202 is fixedly installed at the bottom of the rotating seat 201, and a barb 203 is integrally formed on the ground nail 202. During use, the support base 1 is positioned by inserting the ground nail 202 into the ground, and the barb 203 on the ground nail 202 can improve the installation firmness. The insertion angle and depth of the ground nail 202 are adjusted by rotating the rotating seat 201 to keep the support base 1 level on the uneven ground.

[0029] Both between the support rod 2 and the support base 1 and between the support rod 2 and the rotating seat 201 are positioned by bolts and nuts. During use, the purpose of positioning the angles of the support rod 2 and the rotating seat 201 is achieved by tightening the bolts and nuts.

[0030] The weight of the floating ball 303 is heavier than the weight of the lead weight 304. During use, the decrease in buoyancy during the dewatering process will drive the lead weight 304 to move upward.

[0031] A reflective sheet 305 is fixedly installed at the top of the rope clip 302, and the reflective sheet 305 and the infrared rangefinder 402 are on the same horizontal straight line. During use, the infrared rays emitted by the infrared rangefinder 402 are reflected by the reflective sheet 305 and received by the infrared rangefinder 402 to obtain the distance, and then the water level depth is obtained through control conversion.

[0032] Sound and light alarms 404 are fixedly installed on all four end faces of the controller 401, and a gyroscope 405 is fixedly installed on the top. The sound and light alarm 404 adopts a two-color light design. During use, when the water level crosses the warning line or the support base 1 is not placed horizontally, it can emit a sound and light alarm, and a two-color light design is used for warning distinction.

[0033] Specifically, when the utility model is in use, a support base 1 is built at the opening of a deep foundation pit. The adjusting rod is rotated to adjust the support height. The ground nail 202 is inserted into the ground to position the support base 1. The barbs 203 on the ground nail 202 can improve the installation firmness. The insertion angle and depth of the ground nail 202 are adjusted by rotating the rotating seat 201 so that the support base 1 can be kept horizontal on the uneven ground. During the dewatering process of the deep foundation pit, when the buoyancy of the floating ball 303 decreases, the plumb bob 304 is driven to rise through the connecting rope 301. One of the rope clips 302 rises and the other rope clip 302 descends. The infrared rangefinder 402 emits infrared rays. The infrared rays emitted by the infrared rangefinder 402 are reflected by the reflector 305 and received by the infrared rangefinder 402 to obtain the distance, and then the water level depth is obtained through control conversion. At the same time, when the water level exceeds the warning line or the support base 1 is not horizontally placed, an audible and visual alarm can be issued, and a two-color light design is adopted for warning differentiation.
