Description

Technical Field

[0001] This utility model belongs to the field of surface open channel flow monitoring technology, specifically relating to a fixing device for an underground open channel flow monitoring probe. Background Technology

[0002] In mining operations and surface water conservancy and drainage projects, monitoring the flow of open channels is a crucial task. Accurate flow data plays an irreplaceable role in the rational allocation of water resources, ensuring safe production in mines, and assessing the operational efficiency of water conservancy facilities.

[0003] Currently, existing methods for fixing open channel flow monitoring probes have many shortcomings. On the one hand, some fixing devices have simple structures, relying solely on simple brackets or ropes to suspend the probe in the open channel, which cannot securely fix the probe's position. When the water flow velocity and direction change, the probe is prone to swaying and shifting with the water flow, resulting in deviations in the monitored flow data and failing to accurately reflect the actual flow situation in the open channel.

[0004] On the other hand, while some fixed devices can limit the movement of the probe to a certain extent, the installation process is complex and requires a lot of manpower and time. Moreover, when encountering situations with large water flow impact or complex open channel environments, the stability of these devices is still difficult to guarantee, and problems such as loosening and damage are prone to occur, affecting the normal progress of monitoring work.

[0005] Furthermore, most existing fixed devices lack adaptability to different open channel sizes and flow conditions, and cannot be flexibly adjusted according to actual conditions, further limiting their effectiveness and scope in practical applications. Therefore, developing a fixed device that can effectively fix open channel monitoring probes, improve the accuracy of flow data, is easy to install, and has strong adaptability is of significant practical importance. Utility Model Content

[0006] This invention addresses the problems of existing open channel flow monitoring probe fixing devices, such as probe displacement due to water flow changes, low data accuracy, complex installation, poor stability, and weak adaptability. It provides an underground open channel flow monitoring probe fixing device that ensures the probe can be stably fixed at a designated position in the open channel, thereby obtaining accurate and stable flow data.

[0007] The present invention adopts the following technical solution: A fixing device for a flow monitoring probe in an open channel includes a fixing base adapted to the shape of the bottom of the open channel. The two ends of the fixing base are connected to the bottom of the open channel by expansion bolts. The fixing base has a circular hole, and a telescopic sleeve is provided at the circular hole. The surface of the telescopic sleeve has several perforations for water flow. The flow monitoring probe extends into the telescopic sleeve.

[0008] Furthermore, the bottom of the fixed base is flat.

[0009] Furthermore, the circular hole is located at the center of the fixed base.

[0010] Furthermore, the telescopic sleeve includes a first sleeve and a second sleeve that extends into the first sleeve. The surfaces of the first sleeve and the second sleeve are provided with a plurality of positioning holes, and positioning pins that play a fixing role are provided in the positioning holes.

[0011] Furthermore, the positioning holes are arranged at equal intervals.

[0012] Furthermore, the top end of the telescopic sleeve is provided with a hanging ring.

[0013] Furthermore, the inner diameter of the telescopic sleeve is larger than the outer diameter of the flow monitoring probe.

[0014] The beneficial effects of this utility model are as follows: 1. The bottom of the fixed base of this utility model is optimized to be flat according to the common shape of the bottom of underground open channels, so that it can fully contact the bottom of the open channel, greatly increasing the friction of the contact surface and fundamentally improving the fixing stability.

[0015] 2. The fixed base is secured with expansion screws, providing a solid foundation for the entire fixing device and effectively solving the problem of probe displacement caused by poor contact between the base and the bottom of the open channel or insecure fixing in existing fixing methods.

[0016] 3. This utility model uses a telescopic sleeve, which can adapt to flow monitoring at different water levels.

[0017] 4. By using this utility model, the probe is prevented from shaking under the action of water flow, thus ensuring the detection accuracy and the stability of equipment operation. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described with reference to the accompanying drawings.

[0020] As shown in the figure, a fixing device for a flow monitoring probe in an underground open channel includes a fixing base 1 that is adapted to the shape of the bottom of the open channel. The two ends of the fixing base 1 are connected to the bottom of the open channel by expansion bolts 2. The fixing base 1 is provided with a circular hole 3, and a telescopic sleeve is provided at the circular hole 3. The surface of the telescopic sleeve is provided with several through holes 4 for water flow. The flow monitoring probe 8 extends into the telescopic sleeve.

[0021] Furthermore, the bottom of the fixed base 1 is flat.

[0022] Furthermore, the circular hole 3 is located at the center of the fixed base 1.

[0023] Furthermore, the telescopic sleeve includes a first sleeve 5 and a second sleeve 6 that extends into the first sleeve 5. The surfaces of the first sleeve 5 and the second sleeve 6 are provided with a plurality of positioning holes, and positioning pins that play a fixing role are provided in the positioning holes.

[0024] Furthermore, the positioning holes are arranged at equal intervals.

[0025] Furthermore, the top end of the telescopic sleeve is provided with a hanging ring 7.

[0026] Furthermore, the inner diameter of the telescopic sleeve is larger than the outer diameter of the flow monitoring probe 8.

[0027] The fixing base 1 is secured using a high-strength, corrosion-resistant tray. Its shape is designed to conform to the shape of the open channel bottom, ensuring full contact with the bottom, increasing friction, and improving stability. The fixing base 1 has multiple mounting holes, allowing it to be securely installed on the open channel bottom using expansion bolts or other fasteners.

[0028] The telescopic sleeve is designed to adapt to open channels with different water levels. Several perforations are reserved on the telescopic sleeve for water guidance, which can effectively disperse the impact force of water flow, prevent the probe from shaking under the action of water flow, and ensure detection accuracy and equipment operation stability.

[0029] The telescopic sleeves are made of high-strength, corrosion-resistant metal materials to ensure sufficient strength and stability in complex downhole environments, capable of withstanding water flow impacts and various stresses from long-term use. The telescopic sleeves fit tightly together while retaining a certain amount of room for movement to ensure smooth telescopic adjustment.

[0030] When using this invention, the position is pre-set according to different height requirements. When the height needs to be adjusted to adapt to open channels with different water levels, simply pull the positioning pin out of the current positioning hole, stretch or retract the sleeve to the appropriate position, and then insert the positioning pin into the corresponding positioning hole to achieve precise height adjustment.

[0031] After adjusting the position, insert the flow monitoring probe into the sleeve and connect it via the monitoring cable.

[0032] This invention has made significant technological progress in ensuring stable probe fixation and adapting to different water levels, effectively solving many problems existing in the prior art.
