For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] The following combination Figure 1-Figure 3 , through specific embodiments and application scenarios, a foundation pit monitoring device provided by an embodiment of the utility model is described in detail.

[0027] In view of the fact that the traditional method relies on manual multi-frequency periodic monitoring of the deformation and displacement of the foundation pit slope, there is a lag in management and control, and it increases the difficulty of inspection for management personnel, the utility model can monitor the deformation and displacement of the foundation pit slope in real time and reduce the difficulty of operation.

[0028] like Figure 1 As shown, the present invention provides a foundation pit monitoring device 100, comprising a pole 101, a housing 102, a Beidou locator 103, a signal transmitter 104, and a control panel. Pole 101 is installed at a monitoring point in a foundation pit. Housing 102 is fixedly mounted to pole 101. Beidou locator 103, signal transmitter 104, and control panel are each mounted within housing 102. Beidou locator 103 is electrically connected to the control panel, and the control panel is electrically connected to signal transmitter 104.

[0029] Specifically, if Figure 1 As shown, housing 102 is fixedly mounted on the top of pole 101. Housing 102 is made of a non-metallic material to prevent interference with Beidou positioner 103 and signal transmitter 104. Optionally, housing 102 can be made of waterproof rubber or silicone to provide waterproof protection for the components within housing 102. The control board can be a printed circuit board (PCB) as is known in the art.

[0030] Pole 101 is fixedly installed at a monitoring point in the foundation pit, providing support for box 102 and the components within it. Beidou locator 103 is used to obtain real-time positioning information from the monitoring point on the foundation pit slope. Beidou locator 103 is electrically connected to the control board to transmit real-time positioning information to the control board. The control board is also electrically connected to signal transmitter 104.

[0031] like Figure 2As shown, the signal transmitter 104 is used to communicate with the signal receiver 200, which is in turn communicated with the host computer 300. The control panel transmits the positioning information obtained by the Beidou locator 103 to the signal receiver 200 via the signal transmitter 104, and the signal receiver 200 transmits the positioning information obtained by the Beidou locator 103 to the host computer 300. The host computer 300 can calculate the deformation displacement of the monitoring point by subtracting the initial positioning data of the monitoring point from the positioning data obtained by the Beidou locator 103, making it easier for management personnel to remotely monitor the deformation of the foundation pit slope.

[0032] like Figure 3 As shown, a foundation pit monitoring device 100 is correspondingly installed at several monitoring points of the foundation pit. The signal transmitter 104 of each foundation pit monitoring device 100 is communicatively connected to the signal receiver 200, so that the host computer 300 can simultaneously obtain the real-time positioning data of several monitoring points, which facilitates the management personnel to understand the deformation and displacement of each monitoring point in real time. As a result, the management personnel do not need to frequently visit the several monitoring points of the foundation pit for inspection one by one, which greatly reduces the inspection difficulty of the management personnel. In addition, when the deformation and displacement of the foundation pit slope monitoring point exceeds the preset range, the management personnel can also be informed in time and respond quickly.

[0033] Optionally, the signal transmitter 104 may be an antenna transmitter. The signal transmitter 104 may also be directly connected to a signal receiving terminal on a host computer 300 or a mobile phone or other terminal device, thereby enabling data communication between the foundation pit monitoring device 100 and the outside world.

[0034] The present invention provides a foundation pit monitoring device 100, wherein a vertical pole 101 is used to be inserted into a monitoring point of a foundation pit to provide support for a box 102, and the box 102 is fixedly installed on the vertical pole 101. A Beidou locator 103, a signal transmitter 104 and a control panel are respectively installed in the box 102, so as to realize physical protection of the Beidou locator 103, the signal transmitter 104 and the control panel through the box 102, and the Beidou locator 103 is used to obtain the positioning information of the foundation pit monitoring point, and the Beidou locator 103 is electrically connected to the control panel to transmit the positioning information of the monitoring point to the control panel, and the control panel and the signal transmitter 104 are electrically connected to send the positioning information of the monitoring point to a host computer 300 or a terminal device such as a mobile phone through the signal transmitter 104, so that the management personnel can quickly obtain the deformation and displacement of the monitoring point based on the positioning information of the monitoring point and the initial position information of the monitoring point, and then make management measures in a timely manner. There is no need for manual frequent visits to the foundation pit for on-site monitoring, which reduces the difficulty of inspection for the management personnel.

[0035] In some embodiments, as Figure 1As shown, foundation pit monitoring device 100 also includes a float-type liquid level sensor 105. Pole 101 is a hollow rod. Float-type liquid level sensor 105 is movably disposed within the hollow cavity of pole 101. Float-type liquid level sensor 105 is used to detect the groundwater level at the bottom of the foundation pit when pole 101 is installed at a monitoring point at the bottom of the pit.

[0036] It is understandable that several monitoring points are respectively provided on the slope and bottom of the foundation pit. The groundwater level under the foundation pit is an important factor affecting the deformation, landslide or collapse of the foundation pit slope. Therefore, real-time monitoring of the groundwater level at the monitoring point at the bottom of the pit is of great significance. During installation, the bottom end of the vertical pole 101 is buried below the bottom of the pit, and the float-type liquid level sensor 105 is installed in the hollow cavity of the vertical pole 101 and is located below the bottom of the pit. Construction personnel can adaptively adjust the initial installation position of the float-type liquid level sensor 105 according to the actual geological conditions, the size of the foundation pit grade, the risk factor and the requirements of relevant specifications.

[0037] Optionally, the float type liquid level sensor 105 is arranged in the hollow cavity at a vertical distance of 500 mm below the bottom of the pit.

[0038] For example, for a foundation pit 5 meters deep or deeper, the maximum safe groundwater level is 500 mm below the pit bottom. When the groundwater level is below 500 mm, it indicates that the current groundwater level will not affect the safety of the foundation pit. If the groundwater level reaches or exceeds 500 mm below the pit bottom, construction personnel must immediately implement relevant drainage measures and increase drainage efforts to ensure the safety and stability of the foundation pit.

[0039] The float-type liquid level sensor 105 is initially positioned at the highest safe liquid level. When the groundwater level reaches or exceeds the position of the float-type liquid level sensor 105, the float of the float-type liquid level sensor 105, under the buoyancy of the groundwater, moves upward along the axis of the vertical rod 101 and triggers the sensing element of the float-type liquid level sensor 105. The float-type liquid level sensor 105 is electrically connected to the control board. After receiving the trigger information from the float-type liquid level sensor 105, the control board transmits the trigger information to the signal receiver 200 via the signal transmitter 104. The signal receiver 200 transmits the trigger signal to the host computer 300. This allows remote personnel to quickly understand the groundwater level at the bottom of the pit and take timely measures to respond to the water discharge, reducing the operational complexity for management personnel.

[0040] Furthermore, in some embodiments, Figure 1As shown, the foundation pit monitoring device 100 also includes an alarm 106. Alarm 106 is fixedly mounted inside the housing 102. The Beidou locator 103 and the float-type liquid level sensor 105 are electrically connected to the control panel to transmit positioning information and trigger information of the foundation pit slope monitoring point, respectively, to the control panel. The control panel and alarm 106 are electrically connected.

[0041] It should be noted that in this embodiment, the control board can be a processor with built-in processing capabilities. When the processor determines that the deformation displacement of the current foundation pit slope exceeds a preset range based on the positioning information of the monitoring point, or when the processor receives trigger information from the float-type liquid level sensor 105, the processor immediately controls the alarm 106 to sound an alarm to alert on-site construction personnel, allowing them to respond in a timely manner, which is very convenient.

[0042] Optionally, the alarm 106 is a buzzer alarm.

[0043] Furthermore, in some embodiments, Figure 1 As shown, the foundation pit monitoring device 100 further includes a warning light 107. The warning light 107 is fixedly mounted on the outer wall of the box 102. The Beidou positioner 103 and the float type liquid level sensor 105 are electrically connected to the control board respectively, and the control board is electrically connected to the warning light 107.

[0044] In this embodiment, the control board can be a processor with its own processing function. The Beidou locator 103 is electrically connected to the processor to transmit the positioning information of the monitoring point to the processor. The processor is electrically connected to the warning light 107. The processor can determine whether the deformation displacement of the foundation pit slope exceeds the preset range based on the positioning information of the monitoring point. When the deformation displacement of the foundation pit slope exceeds the preset range, the processor immediately controls the warning light 107 to light up the warning color, so that the on-site management personnel can directly observe the color of the warning light 107 with the naked eye to know the current deformation displacement of the foundation pit slope without the need for external terminal equipment such as the host computer 300, thereby improving the monitoring convenience of the management personnel.

[0045] In addition, the float-type liquid level sensor 105 is electrically connected to the processor to send trigger information to the processor. The processor is electrically connected to the warning light 107. After receiving the trigger information from the float-type liquid level sensor 105, the processor determines that the current groundwater level has reached or exceeded the maximum safe level and immediately controls the warning light 107 to illuminate a warning color. This allows on-site managers to directly observe the color of the warning light 107 to determine the groundwater level. This eliminates the need for external terminal devices such as the host computer 300, thereby improving monitoring convenience for managers.

[0046] In some embodiments, the warning light 107 is a multi-color warning light.

[0047] In this embodiment, the control board can be a processor with its own processing function. The trigger information of the float-type liquid level sensor 105 and the positioning information obtained by the Beidou locator 103 are respectively transmitted to the processor. The processor can control the multi-color warning light to emit different colors based on the above trigger information or positioning information for management personnel to distinguish. For example, when the float-type liquid level sensor 105 is triggered, the processor immediately controls the multi-color warning light to light yellow to prompt the management personnel. For another example, when the processor determines that the current foundation pit slope deformation displacement exceeds the preset range based on the positioning information obtained by the Beidou locator 103, the processor controls the multi-color warning light to light red to prompt the management personnel. Optionally, the multi-color warning light is an LED multi-color light.

[0048] In some embodiments, the foundation pit monitoring device 100 further includes a filter screen. The filter screen is fixed to the cavity wall of the hollow cavity and is located below the float-type liquid level sensor 105. The filter screen is used to filter out solid particles such as mud, gravel, and other impurities in the ground, thereby preventing blockage of the hollow cavity from affecting the movement of the float-type liquid level sensor 105, thereby ensuring the effectiveness of the float-type liquid level sensor 105 in monitoring the groundwater level of the foundation pit.

[0049] In some embodiments, as Figure 1 As shown, the foundation pit monitoring device 100 also includes a solar charging panel 108. The solar charging panel 108 is fixedly mounted on the pole 101 or the outer wall of the housing 102. A power supply 109 is installed within the housing 102. The power supply 109 is electrically connected to the control panel, the Beidou positioner 103, and the signal transmitter 104. The solar charging panel 108 and the power supply 109 are electrically connected.

[0050] Optionally, the solar charging panel 108 can be fixed to the vertical pole 101 by a connecting rod. The connecting rod and the vertical pole 101 are arranged vertically, wherein one end of the connecting rod is fixedly connected to the vertical pole 101, and the other end is fixedly connected to the solar charging panel 108. Alternatively, the connecting rod and the vertical pole 101 can be an integral structure. The semiconductor material of the solar charging panel 108 is arranged facing upward. Optionally, the solar charging panel 108 is hinged to the connecting rod so that on-site construction workers can adjust the angle of attack of the solar charging panel 108 to ensure that the solar charging panel 108 can fully absorb solar energy.

[0051] Optionally, the power source 109 is a lithium battery. The solar charging panel 108 is electrically connected to the lithium battery to charge the lithium battery, which then powers the control panel, Beidou positioner 103, and signal transmitter 104. This eliminates the need for additional charging equipment, is energy-efficient and environmentally friendly, and improves user convenience.

[0052] In some embodiments, the outer wall of the box 102 is provided with polyester label paper or polypropylene label paper. Polyester label paper or polypropylene label paper has good waterproof, wear-resistant and corrosion-resistant properties, so that management personnel can mark monitoring points on the polyester label paper or polypropylene label paper to facilitate on-site monitoring and management.

[0053] In some embodiments, the housing 102 is provided with an inspection window, which is detachably provided with a dustproof plate, so that maintenance personnel can easily open the dustproof plate to inspect components within the housing 102, thereby improving the maintenance convenience of the foundation pit monitoring device 100. Optionally, one of the housing 102 and the dustproof plate is provided with a buckle, and the other is provided with a buckle seat, and the buckle is snapped into the buckle seat, thereby achieving a detachable connection between the dustproof plate and the housing 102.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
