Description

Technical Field

[0001] This invention relates to the field of machinery, specifically to a channel cross-section flow measurement vehicle. Background Technology

[0002] In recent years, with increasing emphasis on hydrological monitoring, most rivers require our inspection. Furthermore, many areas have undertaken large-scale renovations of river nodes, constructing dredging and obstacle removal systems and deploying flood control information monitoring systems to achieve automated, 24 / 7 measurement and monitoring of river ecological flow and water volume.

[0003] In the construction of water conservancy information monitoring systems, the river online flow monitoring system is the vanguard of the entire project, playing a crucial role. Selecting a suitable online flow monitoring device is paramount in this process. There are many methods for monitoring river water volume, such as radar flow meters and Doppler flow monitoring. Currently, when river online flow monitoring systems are installed on rivers, installation and adjustment are inconvenient, and because the equipment is close to the riverbed, it is susceptible to moisture and water ingress, posing safety hazards.

[0016] like Figures 1 to 5As shown, a channel cross-section flow measurement vehicle includes two precast concrete bases 1, located on opposite sides of a riverbank. Support frame assemblies 3 are mounted on the precast concrete bases. Each support frame assembly includes a first support frame 31 and a second support frame 32. A drive mechanism is provided between the first and second support frames. A channel cross-section flow measurement component 4 is mounted on the drive mechanism. The channel cross-section flow measurement component includes a radar flow meter. The radar flow meter is suitable for non-contact measurement of flow velocity, water level, and flow rate in rivers, irrigation canals, underground drainage networks, flood control early warning systems, and other applications. This product features low power consumption, small size, high reliability, and convenient maintenance. The measurement process is unaffected by factors such as temperature, sediment, river pollutants, and floating debris.

[0017] In at least one embodiment, such as Figure 2 The driving mechanism includes a drive motor. The first support frame has a first through hole 311 and a second through hole 312 on its side wall. The drive motor is located inside the first support frame. The drive motor is connected to a first active winding wheel 314. A first driven winding wheel 313 is rotatably connected inside the first support frame. Correspondingly, the second support frame has a third through hole 321 and a fourth through hole 322 on its side wall. A second driven winding wheel 323 and a third driven winding wheel 324 are rotatably connected inside the second support frame. The first active winding wheel, the first driven winding wheel, the second driven winding wheel, and the third driven winding wheel are driven and connected by a traction rope 34.

[0018] The traction rope is equipped with a fixing block 45, and the fixing block is connected to a channel cross-section flow measurement component 4.

[0019] Furthermore, the channel cross-section flow measurement component 4 includes a flow measurement box 41, a fixed frame 42 is provided on the top of the flow measurement box, an auxiliary support wheel 43 is installed on the fixed frame, a connecting rope 44 is provided on the fixed frame, the connecting rope is fixedly connected to the fixed block, and a lead weight 46 is provided at the bottom of the flow measurement box.

[0020] In a more detailed design, a guide rope 33 is provided between the first support frame and the second support frame. An auxiliary support wheel is installed on the guide rope. When the drive mechanism drives the flow meter box to move along the traction rope, the auxiliary support wheel moves along the guide rope.

[0021] In at least one embodiment, such as Figures 3 to 5 As shown, a guide groove 101 is provided in the middle of the precast concrete base, and a lower groove 102 is provided in the center of the guide groove, in which a cable is placed.

[0022] Furthermore, two fixing blocks 2 are slidably fitted in the guide groove, and a first support frame 31 or a second support frame 32 is fixedly installed between the two fixing blocks. Taking the first support frame as an example, the first support frame has a snap-fit ​​groove 301 on its side wall and a fixing plate 302 at its bottom. The fixing blocks have snap-fit ​​blocks 201 that cooperate with the snap-fit ​​groove. The fixing blocks have a slot 202 on their lower side that cooperates with the fixing plate. The slot has an upper hole 203 at its top and a through threaded hole 204 inside the upper hole. A bolt 205 is threaded into the through threaded hole. The lower end of the bolt has a pressing block 206. The pressing block has an anti-slip pad 207. The anti-slip pad is in contact with the upper surface of the fixing plate, causing the anti-slip pad to undergo elastic deformation.

[0023] A fixing plate 208 is provided on one side of the fixing block, and an adjustment knob 209 is provided on the fixing plate. The adjustment knob can make the fixing block move along the guide groove and be positioned at a point on the guide groove.

[0024] Furthermore, a plurality of central tubes 103 are rotatably connected in the lower groove. The central tubes are provided with a plurality of vent holes 104. A rubber expansion sleeve 105 is fitted over the central tubes. The rubber expansion sleeve is provided with a through vent hole 106. An air inlet hole 107 that cooperates with the vent holes is provided on the inner wall of the rubber expansion sleeve.

[0025] When the rubber expansion sleeve is inflated, rotating the central tube connects the vent hole 104 on the central tube with the air inlet. Air then enters the rubber expansion sleeve through the central tube, causing it to expand and filling the gaps between adjacent rubber expansion sleeves. Multiple rubber expansion sleeves can separate the lower compartment into two distinct storage spaces. Placing cables on the central tube prevents moisture and water from the bottom of the lower compartment from affecting the cables. When the central tube is rotated to connect the vent hole 104 with the air outlet 106, a negative pressure mechanism allows moisture in the lower compartment to be transferred to the outside through the air outlet, vent hole, and central tube. Hot air can also be injected through the central tube to raise the air temperature in the lower compartment, keeping it dry.

[0026] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.
