[0001] The utility model relates to the technical field of foundation pit monitoring, in particular to a foundation pit level monitoring device. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane dimensions. Foundation pit monitoring is an important link in the construction of foundation pit projects. It refers to various observations and analyses of the changes in the rock and soil properties of the foundation pit, the displacement of the support structure and the surrounding environmental conditions during the foundation pit excavation and underground engineering construction process. The monitoring results are fed back in a timely manner to predict the deformation and stable state development that will result after further construction. The horizontality of the foundation pit is generally monitored by monitoring devices.

[0003] A foundation pit level monitoring device is disclosed in a Chinese utility model patent with publication number CN218090999U, which includes a main board, a cylinder is fixedly installed on the top of the main board, a monitor is provided on the top of the main board, the output shaft of the cylinder is drivingly connected to a piston rod, a support frame is fixedly installed on the top of the piston rod, a rotating shaft is threadedly connected to the top of the support frame, the monitor is fixedly sleeved on one end of the rotating shaft, and arc blocks are fixedly installed on both sides of the top of the support frame.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device is placed in the foundation pit through the main board. When the surface of the foundation pit is uneven or encounters severe weather such as strong winds, the device is prone to tilt or even fall over, resulting in the inability of the monitoring device to monitor normally, affecting the stability of the monitoring device. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a foundation pit level monitoring device.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a foundation pit level monitoring device, including a base and a monitor arranged on the upper surface of the base, a plurality of U-shaped plates are fixed on the lower surface of the base, the inner wall of each of the U-shaped plates is rotatably connected to a rotating shaft, a support rod is fixedly sleeved on each of the rotating shafts, a mounting opening is penetrated through the side wall of the support rod, a mounting rod is rotatably connected to the inner wall of the mounting opening, a reinforcement component for reinforcing the support rod is installed in the mounting opening, and the reinforcement component includes a mounting plate fixed to the end of the mounting rod, a screw rod penetrated through the mounting plate and threadedly connected, a rotating block fixed to the upper end of the screw rod, and a reinforcement nail fixed to the lower end of the screw rod.

[0007] By adopting the above technical solution, when the monitoring device needs to be fixed, the staff moves the base to a suitable position, rotates and opens multiple support rods and level the monitor, rotates the mounting plate to make the reinforcement nails perpendicular to the ground, and then rotates the screw by rotating the block to move the screw downward and drive the reinforcement nails to drill into the ground, thereby reinforcing the support rods, enhancing the stability of the monitoring device and reducing the probability of the monitoring device tilting or even falling over when the foundation pit surface is uneven or encounters severe weather such as strong winds.

[0008] Furthermore, a limiting assembly for limiting the position of the screw is installed on the support rod, and the limiting assembly includes a threaded rod that is penetrated through the side wall of the support rod and threadedly connected, a star-shaped handle fixed to the end of the threaded rod away from the screw, a guide rod that is penetrated through the side wall of the support rod and slidably connected, and a limiting block that is rotatably connected to the end of the threaded rod away from the star handle and fixed to the end of the guide rod, and the side wall of the limit block away from the guide rod is provided with an arc-shaped groove.

[0009] By adopting the above technical solution, when the monitoring device needs to be moved or carried, the staff rotates the threaded rod through the star-shaped handle. Since the threaded rod is threadedly connected to the support rod, the threaded rod is rotatably connected to the limit block, and the limit block is fixed to the guide rod, the limit block moves to one side of the screw rod and limits the screw rod in the arc groove, thereby avoiding the situation where the reinforcement component is rotated open, and improving the portability of the monitoring device.

[0010] Furthermore, an accommodating groove cooperating with the limiting block is formed on the inner wall of the installation opening.

[0011] By adopting the above technical solution, when the reinforcement component needs to be used, the staff moves the limit block into the receiving groove through the star-shaped handle, thereby reducing the probability that the limit block affects the movement of the reinforcement component.

[0012] Furthermore, an arc-shaped rubber sheet is fixed to the inner wall of the arc-shaped groove.

[0013] By adopting the above technical solution, the arc-shaped rubber sheet is made of rubber material, and the material is elastic, thereby reducing the wear of the arc-shaped groove and the screw.

[0014] Furthermore, one end of the rotating shaft passes through the U-shaped plate and is rotatably connected, and a positioning assembly is installed on the rotating shaft. The positioning assembly includes a positioning nut sleeved on the rotating shaft and threadedly connected to the rotating shaft.

[0015] By adopting the above technical solution, after adjusting the angle of the support rod, the staff needs to tighten the positioning nut so that the side wall of the positioning nut is pressed against the side wall of the U-shaped plate, thereby limiting the rotating shaft and reducing the probability of automatic rotation of the support rod.

[0016] Furthermore, an annular gasket is sleeved on the rotating shaft and is located between the positioning nut and the U-shaped plate.

[0017] By adopting the above technical solution, the annular gasket is made of rubber material, and its surface has a large friction coefficient. The positioning nut cooperates with the U-shaped plate and presses against the annular gasket, which increases the friction between the positioning nut and the U-shaped plate, reduces the probability of the positioning nut rotating, and reduces the wear between the positioning nut and the U-shaped plate.

[0018] Furthermore, a bubble level is fixed to the side wall of the base.

[0019] By adopting the above technical solution and setting the bubble level, the staff can observe the horizontality of the base and the monitor through the bubble level when adjusting the support rod, which is convenient for leveling the monitor.

[0020] Furthermore, a ground nail is fixed to the lower end of each support rod.

[0021] By adopting the above technical solution, the ground nails make the support rods more stably contact with the ground after being rotated and opened, thereby enhancing the stability of the base fixation.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In this application, when the monitoring device needs to be fixed, the staff moves the base to a suitable position, rotates and opens multiple support rods and level the monitor, rotates the mounting plate to make the reinforcement nails perpendicular to the ground, and then rotates the screw rod by rotating the block to move the screw rod downward and drive the reinforcement nails to drill into the ground, thereby reinforcing the support rods, enhancing the stability of the monitoring device and reducing the probability of the monitoring device tilting or even falling when the foundation pit surface is uneven or encounters severe weather such as strong winds;

[0024] 2. In the present application, when the monitoring device needs to be moved or carried, the staff rotates the threaded rod through the star-shaped handle. Since the threaded rod is threadedly connected to the support rod, the threaded rod is rotatably connected to the limit block, and the limit block is fixed to the guide rod, the limit block moves to one side of the screw rod and limits the screw rod in the arc groove, thus avoiding the situation where the reinforcement component is rotated and opened, and improving the portability of the monitoring device;

[0025] 3. In this application, after adjusting the angle of the support rod, the staff needs to tighten the positioning nut so that the side wall of the positioning nut is pressed against the side wall of the U-shaped plate, thereby limiting the rotation axis and reducing the probability of the support rod rotating automatically.

[0031] like Figure 1-3 As shown, an embodiment of the present application discloses a foundation pit level monitoring device, including a base 1, a monitor 2, a U-shaped plate 3, a rotating shaft 4, a support rod 5, a mounting rod 6 and a reinforcement assembly 7.

[0032] The base 1 is a round block-shaped structure, and the base 1 is used to carry the monitor 2. The monitor 2 is a monitor 2 commonly used in the prior art and suitable for the present embodiment, and the monitor 2 is arranged on the upper surface of the base 1. The U-shaped plate 3 is a plate-shaped structure with a U-shaped cross-section, and the U-shaped plate 3 is fixed to the lower surface of the base 1, and a plurality of U-shaped plates 3 are provided. The rotating shaft 4 is a horizontally arranged round rod-shaped structure, and the rotating shaft 4 is rotatably connected to the inner wall of the U-shaped plate 3. A plurality of rotating shafts 4 are provided and correspond one to one with the U-shaped plates 3. The support rod 5 is a rectangular rod-shaped structure, and the support rod 5 is fixedly sleeved on the rotating shaft 4. The side wall of the support rod 5 is penetrated with an installation opening 51, and a plurality of support rods 5 are provided and correspond one to one with the rotating shaft 4. The mounting rod 6 is a horizontally arranged round rod-shaped structure, and the mounting rod 6 is rotatably connected to the inner wall of the mounting opening 51.

[0033] The reinforcement assembly 7 is installed in the installation opening 51 and is used to reinforce the support rod 5. The reinforcement assembly 7 includes a mounting plate 71, a screw rod 72, a rotating block 73 and a reinforcing nail 74. The mounting plate 71 is a rectangular plate-like structure, and the mounting plate 71 is fixed to the end of the mounting rod 6. The screw rod 72 is a vertically arranged rod-like structure, and the screw rod 72 is penetrated and arranged on the mounting plate 71 and is threadedly connected. The rotating block 73 is a round block-like structure, and the rotating block 73 is fixed to the upper end of the screw rod 72, and the axis of the rotating block 73 coincides with the axis of the screw rod 72. The reinforcing nail 74 is fixed to the lower end of the screw rod 72, and the axis of the reinforcing nail 74 coincides with the axis of the screw rod 72.

[0034] When the monitoring device needs to be fixed, the staff moves the base 1 to a suitable position, rotates and opens multiple support rods 5 and level the monitor 2, rotates the mounting plate 71 to make the reinforcement nails 74 perpendicular to the ground, and then rotates the screw 72 by rotating the block 73 to move the screw 72 downward and drive the reinforcement nails 74 to drill into the ground, thereby reinforcing the support rods 5, enhancing the stability of the monitoring device and reducing the probability of the monitoring device tilting or even falling over when the foundation pit surface is uneven or encounters severe weather such as strong winds.

[0035] In order to improve the portability of the monitoring device, a limit assembly 8 is installed on the support rod 5 to limit the screw rod 72. The limit assembly 8 includes a threaded rod 81, a star-shaped handle 82, a guide rod 83 and a limit block 84. The threaded rod 81 is a horizontally arranged rod-shaped structure, which is penetrated and arranged on the side wall of the support rod 5 and threadedly connected. The star-shaped handle 82 is fixed to the end of the threaded rod 81 away from the screw rod 72, and the axis of the star-shaped handle 82 coincides with the axis of the threaded rod 81. The guide rod 83 is a horizontally arranged round rod-shaped structure, which is penetrated and arranged on the side wall of the support rod 5 and slidably connected. The limit block 84 is rotatably connected to the end of the threaded rod 81 away from the star-shaped handle 82, and the limit block 84 is fixed to the end of the guide rod 83. The side wall of the limit block 84 away from the guide rod 83 is provided with an arc groove 841. When the monitoring device needs to be moved or carried, the staff rotates the threaded rod 81 through the star-shaped handle 82. Since the threaded rod 81 is threadedly connected to the support rod 5, the threaded rod 81 is rotatably connected to the limit block 84, and the limit block 84 is fixed to the guide rod 83, the limit block 84 moves toward the side of the screw rod 72 and limits the screw rod 72 in the arc groove 841, thereby avoiding the situation where the reinforcement component 7 is rotated open, thereby improving the portability of the monitoring device.

[0036] In order to reduce the probability that the limit block 84 affects the movement of the reinforcement component 7, a receiving groove 511 cooperating with the limit block 84 is opened on the inner wall of the installation port 51. When the reinforcement component 7 is needed, the staff moves the limit block 84 into the receiving groove 511 through the star-shaped handle 82, thereby reducing the probability that the limit block 84 affects the movement of the reinforcement component 7.

[0037] In order to reduce the wear of the arc groove 841 and the screw rod 72 , an arc rubber sheet 9 is fixed to the inner wall of the arc groove 841 . The arc rubber sheet 9 is made of rubber material with high elasticity, thereby reducing the wear of the arc groove 841 and the screw rod 72 .

[0038] In order to reduce the probability of the support rod 5 rotating automatically, one end of the rotating shaft 4 passes through the U-shaped plate 3 and is rotatably connected. A positioning assembly 10 is installed on the rotating shaft 4, and the positioning assembly 10 includes a positioning nut 101 and an annular gasket 102. The positioning nut 101 is sleeved on the rotating shaft 4 and is threadedly connected to the rotating shaft 4. The axis of the positioning nut 101 coincides with the axis of the rotating shaft 4. The annular gasket 102 is sleeved on the rotating shaft 4, and the annular gasket 102 is arranged between the positioning nut 101 and the U-shaped plate 3. After adjusting the angle of the support rod 5, the staff needs to tighten the positioning nut 101 so that the side wall of the positioning nut 101 cooperates with the side wall of the U-shaped plate 3 and presses against the annular gasket 102, thereby limiting the rotating shaft 4, thereby reducing the probability of automatic rotation of the support rod 5. The annular gasket 102 is made of rubber material, and its surface has a large friction coefficient, which increases the friction between the positioning nut 101 and the U-shaped plate 3, reduces the probability of rotation of the positioning nut 101, and reduces the wear between the positioning nut 101 and the U-shaped plate 3.

[0039] In order to facilitate the leveling of the monitor 2, a bubble level 11 is fixed to the side wall of the base 1. The setting of the bubble level 11 allows the staff to observe the horizontality of the base 1 and the monitor 2 through the bubble level 11 when adjusting the support rod 5, thereby facilitating the leveling of the monitor 2.

[0040] In order to enhance the stability of the base 1 , a ground nail 12 is fixed to the lower end of each support rod 5 . The ground nail 12 enables the support rod 5 to be more stably in contact with the ground after being rotated and opened, thereby enhancing the stability of the base 1 .

[0041] The use principle of a foundation pit level monitoring device in this embodiment is as follows: when the monitoring device needs to be fixed, the staff moves the base 1 to a suitable position, rotates and opens the multiple support rods 5 and levels the monitor 2, rotates the mounting plate 71 to make the reinforcement nails 74 perpendicular to the ground, and then rotates the screw 72 by the rotating block 73 to move the screw 72 downward and drive the reinforcement nails 74 to drill into the ground, thereby reinforcing the support rods 5, enhancing the stability of the monitoring device and reducing the probability of the monitoring device tilting or even falling over when the foundation pit surface is uneven or encounters severe weather such as strong winds.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
