Description

Technical Field

[0001] This invention relates to the field of foundation pit detection technology, and more specifically, to a device for detecting settlement and tilting of building foundation pits. Background Art

[0002] The core function of the foundation pit settlement and tilt detection device is to accurately detect the settlement, tilt angle, and displacement changes of the foundation pit retaining structure and surrounding soil. It can capture structural settlement and tilt caused by changes in geological conditions, load increases or decreases, and other factors in real time, promptly detect anomalies, and issue early warnings of collapse or landslides, thus buying critical time for emergency response and effectively ensuring construction safety. At the same time, its detection data also provides a scientific basis for optimizing construction plans, evaluating project quality, and protecting the safety of surrounding buildings and pipelines, making it an important technical support for the safety management of foundation pit projects.

[0003] The current method for inspecting building foundation pits typically involves setting up industrial measuring cameras around the pit to perform periodic inspections. These cameras are usually encased in protective housings to prevent damage from falling stones. However, to ensure uninterrupted inspection, the housings often have circular holes at the camera lens location. Since these holes are always open, small stones can easily pass through them and damage the lens when the camera is not inspecting the pit, thus affecting its subsequent use. Summary of the Invention

[0004] The purpose of this invention is to provide a device for detecting settlement and tilt of building foundation pits, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A building foundation pit settlement and tilt detection device includes a base plate and an adjustment plate located above the base plate. A protective shell is installed on the upper surface of the adjustment plate. A cavity with an opening at one end for placing an industrial measuring camera is opened inside the protective shell. A fixing component is provided inside the cavity for fixing the position of the industrial measuring camera inside the cavity.

[0007] The upper end face of the adjusting plate is equipped with opposing and sliding opening and closing plates, and the upper end face of the protective shell is provided with an opening and closing assembly. The opening and closing assembly is used to drive the two opening and closing plates to open and close the opening of the cavity.

[0008] The upper surface of the base plate is equipped with an adjustment component, which is used to adjust the tilt angle of the adjustment plate;

[0009] The upper surface of the base plate is also equipped with a positioning component, which is used to position the base plate.

[0010] Preferably, the fixing assembly includes fixing plates that are movably installed opposite each other in the cavity. Both ends of the fixing plates are bent to form fixing parts. The side walls of the two fixing plates that are far apart from each other are each equipped with fixing rods that are opposite each other and penetrate the protective shell. A rotating rod is rotatably installed between the two fixing rods. One end of the rotating rod is threaded through the protective shell.

[0011] Preferably, the upper end of each hinge plate is bent to form a hinged portion, and a round block is installed on the upper end surface of each hinged portion;

[0012] The opening and closing assembly includes two opposing round shafts rotatably mounted on the upper end face of the protective shell. Opening and closing rods are fitted on the outer side walls of both round shafts. Opening and closing grooves for corresponding round blocks to be inserted are opened on the upper end face of each opening and closing rod. A driving component for driving the two round shafts to rotate relative to each other is provided on the upper end face of the protective shell.

[0013] Preferably, gears are fitted onto the outer walls of both circular shafts;

[0014] The drive component includes a rack that is slidably mounted on the upper surface of the protective housing and meshes with two gears.

[0015] Preferably, the lower end face of the rack has a T-shaped groove, and the upper end face of the protective shell is fitted with a locking block that engages with the groove.

[0016] Preferably, the lower end face of the adjusting plate is equipped with opposing first supports, and a first mounting rod is installed between the two first supports. The upper end face of the base plate is fixedly equipped with opposing first support plates whose upper ends are sleeved on the outer side wall of the first mounting rod. The lower end face of the adjusting plate is equipped with opposing second supports, and a second mounting rod is installed between the two second supports. Opposing second support plates are sleeved on the outer side wall of the second mounting rod.

[0017] The adjustment assembly includes a lifting plate movably mounted on the upper surface of the base plate. The upper surface of the lifting plate is equipped with a lifting seat that is rotatably connected to the lower end of the corresponding second support plate. The upper surface of the base plate is provided with a lifting component, which is used to drive the lifting plate to move up and down.

[0018] Preferably, a limiting rod is fixedly installed on the upper end surface of the base plate, which is opposite to and penetrates the lifting plate at its upper end;

[0019] The lifting component includes a stand installed on the upper surface of the base plate. A threaded rod is rotatably installed on the stand facing the side wall of the lifting plate, and the threaded rod is threaded through the lifting plate.

[0020] Preferably, a slot is provided on the upper end face of the base plate, a positioning plate is installed on the upper end face of the base plate, and multiple pointed cones are installed on the lower end face of the positioning plate.

[0021] The positioning assembly includes two bent rods mounted opposite each other on the upper surface of the base plate, a positioning circular plate is installed between the two bent rods, a cylinder is installed on the upper surface of the positioning circular plate, and the output shaft of the cylinder passes through the positioning circular plate and is connected to the upper surface of the positioning plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This invention uses an opening and closing assembly to drive two opening and closing plates closer together and close the opening of the cavity, thereby protecting the lens of the industrial measuring camera. Compared with existing devices, this foundation pit settlement and tilt detection device physically isolates the channel that could enter the cavity and damage the lens when the industrial measuring camera is not in operation. This effectively avoids the risk of foreign objects such as flying or falling gravel damaging the lens of the industrial measuring camera, significantly improving the protective capability and operational reliability of the industrial measuring camera.

[0024] 2. This invention uses two rotating rods to rotate and drive two fixed plates to clamp the industrial measuring camera, achieving lateral clamping of the industrial measuring camera. At the same time, the bent fixing parts at both ends of the fixed plates provide end limits, forming a double lock, which significantly improves the installation stability and anti-displacement ability of the industrial measuring camera in the cavity. In addition, rotating the rotating rods in the opposite direction can quickly release the fixation, facilitating the unobstructed removal and maintenance of the industrial measuring camera. The operation is simple and reliable.

[0025] 3. In this invention, the tilt angle of the adjusting plate is adjusted by adjusting the adjusting component, that is, the adjusting plate tilts towards the foundation pit. The tilting of the adjusting plate, through the protective shell, can drive the industrial measuring camera to tilt, so that the lens of the industrial measuring camera can be adjusted. That is, the lens of the industrial measuring camera can detect different positions in the foundation pit. The second support plate is raised and lowered by the lifting plate, which links the second mounting rod and forces the adjusting plate to rotate around the axis of the first mounting rod, thus realizing precise, stepless and smooth adjustment of the tilt angle of the adjusting plate.

[0026] 4. In this invention, when the base plate is placed on the ground near the foundation pit, it may be tilted by the wind, which may affect the normal use of the industrial measuring camera. To avoid this situation, when the base plate is placed on the ground near the foundation pit, the positioning component can be used to position the base plate, making the base plate more stable on the ground and less likely to be tilted by the wind. This effectively resists the interference of lateral wind force and micro-displacement at the foundation pit site, ensuring the stability of the spatial reference of the industrial measuring camera, and fundamentally guaranteeing the accuracy and reliability of settlement tilt detection data.

[0027] 5. In this invention, a limiting circular plate is installed on the upper end face of the limiting rod. The limiting circular plate limits the movement of the lifting plate. When the lifting plate abuts against the limiting circular plate, the adjusting plate can be adjusted to a horizontal state. The limiting circular plate, as a rigid stop installed at the top of the limiting rod, precisely limits the extreme position of the lifting plate's rise, ensuring that the adjusting plate can be reliably and accurately adjusted to a horizontal state.

[0028] 6. In this invention, both the fixing plate and the fixing part are equipped with rubber pads. The fixing plate and the fixing part are pressed against the side wall of the industrial measuring camera through the rubber pads. By increasing the friction and contact fit of the rubber pads on the fixing plate and the fixing part, the clamping stability and anti-loosening ability of the industrial measuring camera in the cavity are significantly improved. At the same time, its soft material effectively avoids scratches, indentations or deformation of the camera shell caused by direct contact with metal parts, providing reliable surface protection and additional shock absorption.

[0042] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0043] The following is in conjunction with the appendix Figures 1-10 This embodiment will be described in further detail.

[0044] like Figure 1 , Figure 2 and Figure 6 As shown, a building foundation pit settlement and tilt detection device in this embodiment includes a base plate 100 and an adjustment plate 110 located above the base plate 100. A protective shell 120 is installed on the upper end face of the adjustment plate 110. A cavity 421 with an opening at one end for placing an industrial measuring camera 600 is opened inside the protective shell 120. A fixing component is provided inside the cavity 421 for fixing the position of the industrial measuring camera 600 inside the cavity 421.

[0045] The upper end face of the adjusting plate 110 is equipped with opposing and sliding opening and closing plates 130, and the upper end face of the protective shell 120 is provided with an opening and closing assembly. The opening and closing assembly is used to drive the two opening and closing plates 130 to open and close the opening of the cavity 421.

[0046] An adjustment assembly is provided on the upper end face of the base plate 100, which is used to adjust the tilt angle of the adjustment plate 110;

[0047] The upper surface of the base plate 100 is also provided with a positioning component, which is used to position the base plate 100.

[0048] In this embodiment, by placing the industrial measuring camera 600 inside the cavity 421 with its lens facing the opening of the cavity 421, the position of the industrial measuring camera 600 inside the cavity 421 is fixed by the fixing component to prevent it from shaking inside the cavity 421 and colliding with the side wall, thus preventing damage to the industrial measuring camera 600. When the industrial measuring camera 600 needs to perform periodic inspections of the foundation pit, the base plate 100 is placed on the ground near the foundation pit, and then the two opening and closing plates 130 are periodically driven to move closer or further apart by the opening and closing component. When the two opening and closing plates 130 move further apart, the two opening and closing plates 130 release the closure of the cavity 421. At this time, the industrial measuring camera 600 can detect the situation inside the foundation pit and detect whether the bottom wall and side wall of the foundation pit have settled or tilted.

[0049] In this device, after the industrial measuring camera 600 completes the inspection of the foundation pit, the two opening and closing plates 130 are driven to move closer to each other through the opening and closing component, and the opening of the cavity 421 is closed to protect the lens of the industrial measuring camera 600. Compared with the existing devices, this type of foundation pit settlement and tilt detection device can prevent the cavity 421 from always being in an open state during actual use, so that small stones falling through the opening of the cavity 421 can damage the lens of the industrial measuring camera 600.

[0050] The upper end face of the base plate 100 is provided with a T-shaped groove 361 along the moving direction of the opening and closing plate 130. A horizontal plate 500 is installed on the lower end face of the opening and closing plate 130. A protrusion 501 with a T-shaped cross-section is installed on the lower end face of the horizontal plate 500 and is inserted into the groove 361. Through the cooperation of the groove 361 and the protrusion 501, the opening and closing plate 130 is slidably installed on the upper end face of the adjusting plate 110.

[0051] The tilt angle of the adjustment plate 110 is adjusted by the adjustment component, that is, the adjustment plate 110 tilts towards the foundation pit. The tilt of the adjustment plate 110 can drive the industrial measuring camera 600 to tilt through the protective shell 120, so that the lens of the industrial measuring camera 600 can be adjusted. That is, the lens of the industrial measuring camera 600 can detect different positions in the foundation pit, thereby improving the practicality of the industrial measuring camera 600.

[0052] In actual use, when the base plate 100 is placed on the ground near the foundation pit, the base plate 100 may be blown tilted by the wind, which will affect the normal use of the industrial measuring camera 600. In order to avoid this situation, when the base plate 100 is placed on the ground near the foundation pit, the position of the base plate 100 is positioned by the positioning component, so that the base plate 100 is placed on the ground more stably and is not easily blown tilted by the wind.

[0053] like Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, in this embodiment, the fixing component includes a fixing plate 410 that is movably installed in the cavity 421. Both ends of the fixing plate 410 are bent to form fixing parts 411. The side walls of the two fixing plates 410 that are far apart from each other are each equipped with a fixing rod 611 that is opposite to each other and penetrates the protective shell 120. A rotating rod 610 is rotatably installed between the two fixing rods 611. One end of the rotating rod 610 is threaded through the protective shell 120.

[0054] In this embodiment, the rotating rod 610 is rotatably mounted inside the side wall of the fixing plate 410 via a bearing. The fixing plate 410 is limited by two fixing rods 611. When the industrial measuring camera 600 is placed inside the cavity 421, the two rotating rods 610 are driven to rotate. The rotating rods 610 can drive the fixing plate 410 to move toward the industrial measuring camera 600. When both fixing plates 410 are pressed against the side wall of the industrial measuring camera 600, the industrial measuring camera 600 is fixed inside the cavity 421. At the same time, the fixing parts 411 at both ends of the fixing plate 410 can limit the two ends of the industrial measuring camera 600, improving the fixing effect of the industrial measuring camera 600 inside the cavity 421.

[0055] When the two fixed plates 410 are driven away from the industrial measuring camera 600 by the rotating rod 610, the industrial measuring camera 600 is released from the cavity 421. At this time, the industrial measuring camera 600 can be taken out from the cavity 421, which is convenient for the industrial measuring camera 600 to be inspected and repaired.

[0056] Both the fixing plate 410 and the fixing part 411 are equipped with rubber pads. The fixing plate 410 and the fixing part 411 are pressed against the side wall of the industrial measuring camera 600 through the rubber pads, so that the industrial measuring camera 600 is better fixed in the cavity 421. At the same time, it can also prevent the side wall of the industrial measuring camera 600 from being scratched by the fixing plate 410 or the fixing part 411.

[0057] The through end of the rotating rod 610 is equipped with a handle 220, which facilitates the rotation of the rotating rod 610.

[0058] In actual use, a fixed circular plate 350 is fixedly installed at the through end of the fixed rod 611. The fixed circular plate 350 limits the fixed rod 611, thereby preventing the rotating rod 610 from driving the fixed plate 410 to move too much, which would cause the fixed rod 611 to detach from the protective shell 120 and affect the actual use.

[0059] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the upper end of the opening and closing plate 130 is bent to form an opening and closing part 131, and a round block 300 is installed on the upper end surface of the opening and closing part 131.

[0060] The opening and closing assembly includes two opposing round shafts 310 rotatably mounted on the upper end face of the protective shell 120. Opening and closing rods 311 are sleeved on the outer side walls of both round shafts 310. Opening and closing grooves 312 for corresponding round blocks 300 to be inserted are opened on the upper end face of each opening and closing rod 311. The upper end face of the protective shell 120 is provided with a driving component for driving the two round shafts 310 to rotate relative to each other.

[0061] In this embodiment, the lower end of the round shaft 310 is rotatably mounted in the upper end face of the protective shell 120 via a bearing. The opening and closing groove 312 is arranged along the length direction of the opening and closing rod 311, which is fixedly sleeved on the outer side wall of the round shaft 310. When the driving component drives the two round shafts 310 to rotate relative to each other, the round shaft 310 can drive the opening and closing rod 311 to swing. The swing of the opening and closing plate 130, through the cooperation of the opening and closing groove 312 and the round block 300, allows the swing of the opening and closing rod 311 to drive the opening and closing part 131 to move through the round block 300. That is, the movement of the opening and closing plate 130 opens and closes the opening of the cavity 421.

[0062] like Figure 3 and Figure 4 As shown, in this embodiment, gears 320 are fitted on the outer walls of both round shafts 310;

[0063] The driving component includes a rack 330 that is slidably mounted on the upper surface of the protective housing 120 and meshes with two gears 320.

[0064] In this embodiment, the gear 320 is fixedly sleeved on the outer side wall of the round shaft 310. When the rack 330 moves, the rack 330 can drive the two gears 320 to rotate. The rotation of the gears 320 can drive the corresponding round shaft 310 to rotate, that is, the round shaft 310 drives the opening and closing rod 311 to swing.

[0065] Among them, the lower end face of the rack 330 is provided with a T-shaped groove, and the upper end face of the protective shell 120 is provided with a locking block 340 that is inserted into the groove. Through the cooperation between the locking block 340 and the groove, the rack 330 can be slidably installed on the upper end face of the protective shell 120.

[0066] In actual use, a mounting shell 140 is fixedly installed on the upper end face of the protective shell 120. A mounting block 401 is installed on the side wall of the mounting shell 140 facing the protective shell 120. An electric push rod 400 is installed between the mounting block 401 and the side wall of the mounting shell 140. A push block 331 is installed on the upper end face of the rack 330. The push block 331 is fixedly connected to the output shaft of the electric push rod 400, so that the push block 331 is moved by the electric push rod 400, that is, the rack 330 is moved.

[0067] like Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, in this embodiment, the lower end face of the adjusting plate 110 is equipped with opposing first supports 200, and a first mounting rod 201 is installed between the two first supports 200. The upper end face of the base plate 100 is fixedly equipped with opposing first support plates 150, the upper end of which is sleeved on the outer side wall of the first mounting rod 201. The lower end face of the adjusting plate 110 is equipped with opposing second supports 210, and a second mounting rod 211 is installed between the two second supports 210. The outer side wall of the second mounting rod 211 is sleeved with opposing second support plates 151.

[0068] The adjustment assembly includes a lifting plate 160 movably mounted on the upper surface of the base plate 100. The upper surface of the lifting plate 160 is equipped with a lifting seat 841 that is rotatably connected to the lower end of the corresponding second support plate 151. The upper surface of the base plate 100 is provided with a lifting component, which is used to drive the lifting plate 160 to move up and down.

[0069] In this embodiment, the first support plate 150 is connected to the first mounting rod 201 by a bearing, and the upper end of the second support plate 151 is connected to the second mounting rod 211 by a bearing. When the lifting component drives the lifting plate 160 to adjust its height, the lifting plate 160 can drive the second support plate 151 to move up and down through the lifting seat 841. The lifting of the second support plate 151 can drive the adjusting plate 110 to rotate along the first mounting rod 201 through the second mounting rod 211, thereby adjusting the tilt angle of the adjusting plate 110.

[0070] In actual use, lifting blocks 842 are installed on the side wall of the lifting seat 841 facing the second support plate 151. The lifting blocks 842 are rotatably installed on the side wall of the corresponding second support rod through bearings, so as to realize the rotational connection between the second support plate 151 and the lifting seat 841.

[0071] like Figure 9 As shown, in this embodiment, a limiting rod 161 with its upper end penetrating the lifting plate 160 is fixedly installed on the upper surface of the base plate 100.

[0072] The lifting component includes a stand 850 mounted on the upper surface of the base plate 100. A threaded rod 851 is rotatably mounted on the side wall of the stand 850 facing the lifting plate 160. The threaded rod 851 is threaded through the lifting plate 160.

[0073] In this embodiment, the two ends of the lifting plate 160 are limited by two limiting rods 161, and the two ends of the threaded rod 851 are rotatably mounted on the upright frame 850 through bearings. When the threaded rod 851 rotates, the threaded rod 851 can drive the lifting plate 160 to rise and fall, that is, adjust the tilt angle of the adjusting plate 110.

[0074] Among them, the upper end face of the limiting rod 161 is equipped with a limiting circular plate 840. The limiting circular plate 840 limits the movement of the lifting plate 160. When the lifting plate 160 abuts against the limiting circular plate 840, the adjusting plate 110 can be adjusted to a horizontal state.

[0075] In actual use, a motor 852 is fixedly installed on the upper end face of the base plate 100. The output shaft of the motor 852 is connected to the threaded rod 851, so that the threaded rod 851 can be driven to rotate by the motor 852.

[0076] like Figure 1 and Figure 9 As shown, in this embodiment, a slot is provided on the upper end face of the base plate 100, a positioning plate 830 is installed on the upper end face of the base plate 100, and a plurality of pointed cones 831 are installed on the lower end face of the positioning plate 830.

[0077] The positioning assembly includes two bent rods 801 mounted opposite each other on the upper surface of the base plate 100. A positioning circular plate 800 is installed between the two bent rods 801. A cylinder 810 is installed on the upper surface of the positioning circular plate 800. The output shaft of the cylinder 810 passes through the positioning circular plate 800 and is connected to the upper surface of the positioning plate 830.

[0078] In this embodiment, the positioning plate 830 is driven to move towards the slot by the cylinder 810, so that the pointed cone 831 on the lower end face of the positioning plate 830 can pass through the slot and insert into the ground, thereby positioning the base plate 100 on the ground and making the placement of the base plate 100 on the ground more stable.

[0079] Among them, the upper end face of the base plate 100 is equipped with multiple vertical rods 820, which limit the positioning plate 830, making the movement of the positioning plate 830 more stable, so that multiple pointed cones 831 can be better inserted into the ground.

[0080] In actual use, when the base plate 100 needs to be moved, the cylinder 810 drives the positioning plate 830 to move upward, so that the pointed cone 831 on the lower end face of the positioning plate 830 is located in the groove.

[0081] In practical use, this embodiment involves placing the base plate 100 on the ground near the foundation pit. Then, the positioning plate 830 is moved downwards by the cylinder 810, causing the pointed cone 831 on the lower end face of the positioning plate 830 to insert into the ground. When the foundation pit needs to be inspected, the rack 330 is moved by the electric push rod 400. The movement of the rack 330 drives the round shaft 310 to rotate via the gear 320. The rotation of the round shaft 310 drives the opening and closing plate 130 to open / close via the opening and closing rod 311. When the two opening and closing plates 130 release the closure of the cavity 421, the lens of the industrial measuring camera 600 can inspect the pit through the opening of the cavity 421. After the industrial measuring camera 600 completes the inspection of the pit, the electric push rod 400 drives the rack 330 to move. The movement of the rack 330 drives the round shaft 310 to rotate through the gear 320. The rotation of the round shaft 310 drives the opening and closing plate 130 to close the opening of the cavity 421 through the opening and closing rod 311.

[0082] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
