Description

Technical Field

[0001] The present invention relates to the technical field of leveling measurement, and particularly to a single-connected high-precision hydrostatic level. Background Art

[0002] A hydrostatic level is a high-precision measuring device mainly used for monitoring the settlement, displacement, and terrain changes of structures. It accurately measures the relative height changes between different monitoring points through the water level in a series of connected containers. This method is particularly suitable for long-term stability monitoring of large infrastructure projects such as bridges, tunnels, dams, etc.

[0003] A hydrostatic level system usually consists of multiple interconnected sensors. Each sensor includes a container filled with liquid and a gas channel connected thereto. When the system is in a stable state, the liquid levels in each sensor should be consistent, so as to judge whether there is settlement or uplift by measuring the change of the liquid level. The change of the internal gas pressure of the system will be captured by the high-precision pressure sensor in the sensor, and the height difference between each measuring point will be calculated accordingly. When the temperature rises, the liquid expands and the liquid level rises; when the temperature drops, the liquid contracts and the liquid level drops. This non-settlement-induced liquid level change will interfere with the identification of the true settlement signal and cause errors. Summary of the Invention

[0029] Please refer to Figures 1 to 6 , the present invention provides a simply-connected high-precision static level, which includes a level body 101 and a mounting seat 102. The mounting seat 102 is fixed to the level body 101. A gas connection pipe and a liquid connection pipe are provided on the mounting seat 102. It also includes a coplanar flange 103 and a temperature control structure; the coplanar flange 103 includes a flange body 105, two gas pipelines 106, a gas three-way joint 107, two liquid pipelines 108, and a liquid three-way joint 109. The flange body 105 has a heating cavity 110. The two gas pipelines 106 pass through the flange body 105 and are connected to the gas three-way joint 107 installed in the heating cavity 110. The gas three-way joint 107 is also communicated with the gas connection pipe. The two liquid pipelines 108 pass through the flange body 105 and are connected to the liquid three-way joint 109 installed in the heating cavity 110. The liquid three-way joint 109 is also connected to the liquid connection pipe; the temperature control structure includes a heating resistance tube 111, a cover plate 112, and a power supply connector 113.

The power supply connector 113 is connected to the heating resistance tube 111 and passes through the flange body 105; the cover plate 112 is fixedly connected to the flange body 105 and closes the heating cavity 110.

[0030] In this embodiment, the level includes a level body 101 and a mounting seat 102. The mounting seat 102 is fixedly connected to the level body 101 and is used to support and position the whole device. A gas connection pipe and a liquid connection pipe are provided on the mounting seat 102, which are respectively used to transmit gas and liquid media to achieve the balance and measurement of the liquid level height.

[0031] The coplanar flange 103 is used as the core connecting component to achieve fluid communication between multiple measuring points and ensure the sealing and stability between the connecting channels. Inside the flange body 105, there is a heating cavity 110 for accommodating key fluid connection components. Two gas pipelines 106 pass through the flange body 105 and are connected to a gas three-way joint 107 inside the heating cavity 110. The gas three-way joint 107 is also connected to the gas connection pipe on the mounting seat 102, thus realizing the intercommunication of the gas path. Similarly, two liquid pipelines 108 also pass through the flange body 105 and are connected to a liquid three-way joint 109 arranged inside the heating cavity 110.

[0032] To improve the adaptability and measurement accuracy of the instrument under different ambient temperatures, the present invention particularly provides a temperature control structure. The temperature control structure includes a heating resistance tube 111, a cover plate 112, and a power supply connector 113. The heating resistance tube 111 is arranged inside the heating cavity 110 of the flange body 105 and is used for the constant temperature control of the gas and liquid media flowing through the flange to prevent the volume expansion or contraction of the media caused by the change of the external temperature, thereby affecting the measurement accuracy. The power supply connector 113 is electrically connected to the heating resistance tube 111 and passes through the flange body 105 to be led out so that an external power supply can supply power to it. The cover plate 112 is fixedly connected to the flange body 105 and tightly seals the heating cavity 110, playing a role in protecting the internal components and maintaining the heat stability.

[0033] In summary, the single-connected high-precision hydrostatic level provided by the present invention realizes the efficient connection of gas and liquid between multiple measuring points through the optimized design of the coplanar flange 103. At the same time, combined with the temperature control structure, it effectively eliminates the influence of temperature fluctuations on the measurement results, significantly improves the measurement accuracy and long-term stability of the instrument, and is suitable for engineering application occasions such as high-precision deformation monitoring and settlement observation.

[0034] The coplanar flange 103 further includes a first sealing ring 114, and the first sealing ring 114 is arranged at the connection between the flange body 105 and the mounting seat 102.

[0035] The coplanar flange 103 further includes a first sealing ring 114, and the first sealing ring 114 is arranged at the connection between the flange body 105 and the mounting seat 102. Through the design of this sealing ring, it can effectively prevent the leakage of gas and liquid media at the interface between the flange and the mounting seat 102, thereby improving the sealing performance of the entire system, ensuring the stability and accuracy of the liquid level height during the measurement process, and also helping to extend the service life of the equipment and avoid corrosion or failures caused by medium leakage.

[0036] The coplanar flange 103 further includes a stabilizing rod 115, which is used to support the gas three-way joint 107 and the liquid three-way joint 109.

[0037] To enhance the structural stability of the internal pipeline connection components of the flange, the coplanar flange 103 is also provided with a stabilizing rod 115 for supporting and fixing the gas three-way joint 107 and the liquid three-way joint 109.

[0038] The stabilizing rod 115 includes a support rod 116 and an elastic clamping rod 117. The support rod 116 is fixed inside the heating cavity 110, the elastic clamping rod 117 is fixed to the support rod 116, and the gas three-way joint 107 and the liquid three-way joint 109 are arranged in the groove of the elastic clamping rod 117.

[0039] The support rod 116 is fixedly installed on the inner wall of the heating cavity 110 as the basis of the overall support structure; the elastic clamping rod 117 is fixedly connected to the end of the support rod 116 and is provided with a groove structure. The gas three-way joint 107 and the liquid three-way joint 109 are embedded and clamped in the groove, and the fastening characteristics of the elastic material are used to achieve stable positioning. This design can not only effectively prevent the three-way joint from displacing or loosening due to fluid pressure or vibration during operation, but also absorb a certain amount of mechanical shock, thereby improving the reliability and safety of the system operation.

[0040] The temperature control structure further includes a heat insulation sleeve 118 and a second sealing ring 119. The heat insulation sleeve 118 is arranged inside the heating cavity 110, and the second sealing ring 119 is arranged between the heat insulation sleeve 118 and the cover plate 112.

[0041] The heat insulation sleeve 118 is arranged inside the heating cavity 110 and is wrapped around the heating resistance tube 111, which is used to isolate the outward diffusion of heat, reduce energy loss, and prevent the outside of the heating cavity 110 from being affected by local overheating and affecting the normal operation of other components due to local overheating. The heat insulation sleeve 118 is made of a material with high temperature resistance and low thermal conductivity, and has good thermal stability and insulation performance.

[0042] The second sealing ring 119 is arranged between the heat insulation sleeve 118 and the cover plate 112, which plays a dual role: on the one hand, it ensures the airtightness and liquid tightness of the heating cavity 110 in the closed state, preventing external moisture or impurities from invading and affecting the working efficiency of the heating element; on the other hand, it also enhances the fit between the heat insulation layer and the cover plate 112, which helps to maintain the uniformity and stability of the temperature field inside the heating cavity 110.

[0043] The single-connected high-precision hydrostatic level further includes a connection structure, which includes a rotating block 120, an extension plate 121, an elastic member 122, a screw locking rod 123, a docking plate 124 and a buckle 125. The rotating block 120 is rotatably arranged on one side of the flange body 105. The extension plate 121 is slidably arranged on one side of the rotating block 120. The buckle 125 is arranged on the extension plate 121. The elastic member 122 is arranged between the rotating block 120 and the extension plate 121. The screw locking rod 123 is rotatably connected to the rotating block 120 and is threadedly connected to the extension plate 121. The docking plate 124 is fixedly connected to the flange body 105 and is inserted into the installation groove 133 of the mounting seat 102.

[0044] The rotating block 120 in the connection structure is arranged on one side of the flange body 105 and realizes rotational movement relative to the flange body 105 through a rotating shaft. The extension plate 121 is slidably arranged on one side of the rotating block 120, and it can perform telescopic movement along a straight line on the rotating block 120, so as to adjust the overall connection length to adapt to mounting seats 102 with different sizes or position requirements. In order to realize the locking control of the displacement of the extension plate 121, the screw locking rod 123 is rotatably connected to the rotating block 120 and is in threaded cooperation with the extension plate 121. By tightening or loosening the screw locking rod 123, the extended length of the extension plate 121 can be precisely controlled and the buckle 125 can be fixed at the corresponding position of the mounting seat 102.

[0045] The elastic member 122 is arranged between the rotating block 120 and the extension plate 121, usually composed of a compression spring or other elastic materials, and is used to provide a restoring force, so that the extension plate 121 can automatically retract to the initial position when not subjected to external forces. At the same time, it also plays a role in buffering and shock absorption to prevent the connection structure from being damaged or loosened due to external impacts.

[0046] The buckle body 127 includes a gear 126 and a buckle body 127. The gear 126 is rotatably arranged on the extension plate 121. The buckle body 127 is fixedly connected to the gear 126. The connection structure further includes a rack 128. The rack 128 is fixed on one side of the rotating block 120. When the extension plate 121 moves a preset distance, the gear 126 meshes with the rack 128 to drive the buckle body 127 to rotate. The mounting seat 102 is provided with a card slot 129 corresponding to the buckle body 127.

[0047] The gear 126 is mounted on the extension plate 121 through a rotating shaft, and teeth are provided in a partial area thereof; the buckle body 127 is synchronously rotationally connected to the gear 126. When the gear 126 rotates, it will drive the buckle body 127 to rotate together. In addition, the rack 128 is fixed to one side of the rotating block 120. After the extension plate 121 slides a preset distance in a specific direction, the gear 126 will mesh with the rack 128, thereby driving the buckle body 127 to rotate to a predetermined angle, and making the top end thereof insert into the card slot 129 on the mounting seat 102 to complete the locking action.

[0048] The cross-section of the card slot 129 is an inclined L shape. A damping block 130 is provided at the top end of the buckle body 127. When the buckle body 127 rotates, the damping block 130 enters the L-shaped bottom of the card slot 129 to be clamped tightly.

[0049] The cross-section of the card slot 129 is designed as an inclined L-shaped structure. This design enables the buckle body 127 to first slide in along the inclined plane and then be clamped into the L-shaped bottom when rotating into the card slot 129 to achieve stable locking. At the same time, a damping block 130 is provided at the top end of the buckle body 127. The damping block 130 is made of a material with certain elasticity and friction performance, and can provide additional frictional resistance during the process of the buckle body 127 rotating into the card slot 129, ensuring that the buckle body 127 is firmly fixed in the card slot 129 and avoiding falling off or loosening due to vibration or external force.

[0050] The docking plate 124 includes a docking plate body 131 and a rotating shaft 132. The cross-section of the mounting groove 133 is triangular, and a circular groove 134 is provided at the bottom of the triangle, so that the rotating shaft 132 can enter the circular groove 134 to allow the docking plate body 131 to rotate a preset angle.

[0051] In addition, the connection structure further includes a docking plate 124 for realizing the auxiliary connection and positioning between the flange body 105 and the mounting seat 102. The docking plate 124 includes a docking plate body 131 and a rotating shaft 132. The mounting seat 102 is provided with a mounting groove 133 with a triangular cross-section, and a circular groove 134 is opened at the bottom of the triangle, so that the rotating shaft 132 of the docking plate body 131 can smoothly enter the circular groove 134 and allow the docking plate body 131 to rotate a preset angle within a certain range. This design not only improves the flexibility of the docking process, but also can automatically center during the installation process, improving the accuracy and stability of the connection.

[0052] In summary, by introducing the above connection structure, the installation convenience, connection reliability, and environmental adaptability of the static level in practical applications have been significantly improved. This structure not only has good adjustment freedom but also realizes an automatic locking function through a mechanical linkage mechanism (such as the cooperation between gear 126 and rack 128). At the same time, with the help of damping block 130, elastic member 122, and the rotation mechanism of docking plate 124, the seismic resistance and sealing performance of the system are enhanced. Therefore, this single-connected high-precision static level is particularly suitable for high-precision measurement occasions such as settlement monitoring under complex terrain conditions, bridge deformation detection, and building engineering safety monitoring, and has broad application prospects and practical value.

[0053] The temperature control structure further includes a temperature sensor, a data detection unit, a control unit, and an alarm unit. The temperature sensor is arranged in the heating cavity 110, and the data detection unit is used to calculate the temperature data in the heating cavity 110 based on the sensor data. The control unit is used to control the power of the heating resistance tube 111 based on the temperature data, and the alarm unit is used to give an alarm when the temperature exceeds the preset range.

[0054] The temperature sensor is arranged in the heating cavity 110 of the flange body 105, preferably near the heating resistance tube 111 or around the fluid channel, for collecting the temperature data inside the heating cavity 110 in real time. This sensor has high sensitivity and high stability, can quickly respond to temperature changes, and output corresponding electrical signals, providing an accurate basis for subsequent data processing.

[0055] The data detection unit is electrically connected to the temperature sensor, used to receive the original signal collected by the sensor, and perform processing such as filtering, amplification, and analog-to-digital conversion on it, and finally calculate the actual temperature value in the current heating cavity 110.

[0056] The control unit is implemented by a microprocessor or a programmable logic controller (PLC). It is communicatively connected to the data detection unit, compares the currently measured temperature data with the preset target temperature value, and automatically adjusts the working power of the heating resistance tube 111. For example, when it is detected that the temperature is lower than the set value, the control unit will increase the heating power to speed up the heating; when the temperature approaches or reaches the set value, the power will be reduced to enter the heat preservation state, or even the heating function will be turned off, so as to achieve precise PID (Proportional-Integral-Derivative) control and keep the temperature stable within ±0.1°C, significantly improving the measurement accuracy of the instrument.

[0057] To enhance the security and reliability of the system, the temperature control structure is also provided with an alarm unit. This alarm unit is connected to the control unit and is used to send an alarm signal in a timely manner when the temperature exceeds the preset range. This preset range can be flexibly set according to different usage environments and medium characteristics. Once the temperature is too high or too low and continuously exceeds the set threshold, the alarm unit will remind the operator to take corresponding measures through methods such as sound and light, wireless communication, or remote interface, to prevent equipment damage or measurement failure caused by abnormal temperature.

[0058] In some embodiments, the alarm information can also be uploaded to a remote monitoring system or a mobile platform to achieve remote fault early warning and maintenance scheduling, greatly improving the security and intelligent level of equipment operation.

[0059] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the invention.
