[0002] With the continuous development of technology, the construction of urban buildings has begun to increase, and some river channels near the city have been renovated to form better dredging of the water flow channels. River channels or reservoirs can provide water sources for the city and also enable the diversion of water flow during flood seasons. Therefore, the treatment of river channels is also relatively important, and it is necessary to regularly detect the water level and other flow rates of the river channel water.

[0003] The existing equipment used for detecting the water flow of river channels is large in overall size and not convenient for movement. It requires vehicle transportation, resulting in difficulties in detecting the river hydrology. Due to the different water flows in the river channels, real-time adjustment is required during the use of the detection equipment to avoid abnormal detection problems. Summary of the Utility Model

[0004] An embodiment of the present disclosure relates to a portable flow velocity measuring instrument. A guide plate is provided at the bottom of the hull assembly. When the hull assembly is placed on the water surface, it forms a role of following the water flow guidance. After the hull assembly is flipped, it can move to any position. A connection assembly is connected and installed at the bottom position of the hull assembly. After the device is placed in the water, the balance assembly can be placed in the water through the connection assembly, enabling the balance assembly to better detect the water flow through the speed measurement assembly. The fixing assembly can adjust the swing angle of the connection assembly to increase the depth adjustment of the balance assembly.

[0005] In the first aspect of the present disclosure, a portable flow velocity measuring instrument is provided, specifically including: a hull assembly; a guide plate is provided at the bottom of the hull assembly, a clamping frame is provided at the middle left position of the hull assembly, a fixing assembly is installed at the upper left position of the hull assembly, a connection assembly is hinged and installed at the lower end of the position where the hull assembly installs the fixing assembly, the end of the connection assembly is connected and installed with a balance assembly, and a speed measurement assembly is rotatably installed inside the balance assembly.

[0006] In at least some embodiments, the carrying ship of the hull assembly is set as a plate-like structure, an expansion frame is hinged and installed at the left position of the carrying ship, and two groups of wheels are rotatably installed at the right position of the carrying ship.

[0007] In at least some embodiments, the fixing block of the fixing assembly is provided at the upper end of the hull assembly, a fixing plate is rotatably installed at the fixing block, a fixing column is screwed and installed on the fixing plate, and the bottom of the fixing column corresponds to the position of the connection assembly.

[0008] In at least some embodiments, the connecting rod of the connecting component is hingedly installed at the bottom position of the hull component. The root position of the connecting rod is set as a contact head, and a connecting frame is connected to the end position of the connecting rod.

[0009] In at least some embodiments, the balance cylinder of the balance component is set as a cylindrical structure. The balance cylinder is connected to the end position of the connecting component. A balance plate is fixed on the outer wall of the balance cylinder, and the balance plate at the connection position between the balance cylinder and the connecting component adopts an enlarged shape.

[0010] In at least some embodiments, the inner column rod of the speed measurement component is set as a columnar structure. The inner column rod is rotatably installed inside the balance component, and three groups of speed measurement vanes are arranged outside the inner column rod. Each group of speed measurement vanes is set as a spiral vane structure.

[0011] In at least some embodiments, three groups of guide plates are arranged at the bottom of the hull component. Each group of guide plates is triangular. A clamping frame is arranged at the middle position of the bottom of the hull component, and the clamping frame is fixedly clamped with the balance component.

[0012] The utility model provides a portable flow velocity measuring instrument, which has the following beneficial effects:

[0013] In the utility model, a clamping frame is arranged at the middle of the bottom of the hull component. When the connecting component is retracted and the balance component is closely attached to the bottom of the hull component, the balance component can be clamped and installed at the bottom position of the clamping frame, realizing the stable retraction of the balance component and the connecting component. Thus, after the whole hull component is flipped, when the extension frame is rotated in the opposite direction at the same time, the wheels of the hull component are placed on the ground, which is convenient for the device to move. After the connecting component and the balance component at the bottom of the hull component are unfolded, the swinging position of the connecting component is adjusted, so that the balance component at the end of the connecting component is placed at a specified depth. At this time, the fixing component is pressed against the root position of the connecting component, realizing the fixing of the connecting component by the fixing component. After the whole hull component is lifted and placed on the water surface, the guide plates at the bottom of the hull component will guide the hull component, making the hull component follow the water flow direction. The balance plate at the end of the connecting component will, under the action of the water flow, make the balance component in a horizontal state, enabling the balance component to better detect the water flow with the speed measurement component.

[0014] In addition, the extension frame hingedly installed at the left side of the carrying ship can be used either by hand or by connecting a pull rope. The rotatably installed wheels, after the whole hull component is flipped, place the wheels on the ground, thus facilitating the overall movement of the device.

[0015] In addition, the connecting rod is arranged to be hinged, and a contact head is provided at the root position of the connecting rod, so that the contact head can contact the fixing component. After the connecting rod swings at the required angle, the connecting rod is fixed by the fixing component, and the connecting frame at the end of the connecting rod has the function of assisting in connecting with the balancing component.

[0016] In addition, the balance cylinder is directly arranged at the end of the connecting component, so that the balance cylinder can be placed in water through the connecting component. The balance plate on the outer wall of the balance cylinder has the function of keeping the balance cylinder placed in water stable and horizontal. The balance plate at the connection between the balance cylinder and the connecting component is enlarged to make the horizontal state of the balance cylinder more stable.

[0017] In addition, the inner column rod is arranged to be rotatably installed inside the balancing component, and three groups of speed measuring blades are arranged on the inner column rod. The speed measuring blades are arranged in a spiral shape. After the balancing component is placed in water, when there is water flow passing through, the spiral speed measuring blades rotate to realize the detection effect of the water flow rate.

[0018] In addition, after the hull component is placed on the water surface as a whole, the guiding plate on the upper part of the hull component can contact the water flow first, so that the water flow can guide the whole hull component through the guiding plate, making the hull component in the same direction as the water flow, which is convenient for the balancing component and the speed measuring component to detect the water flow rate. A clamping frame is directly arranged in the middle of the bottom of the hull component. After the balancing component swings and retracts through the connecting component, the clamping frame contacts and clamps with the balancing component, so that the balancing component is stably fixed on the hull component through the clamping frame, making it more convenient and stable to retract and move the device subsequently.
