[0002] Currently, water conservancy projects frequently require the measurement of flow velocity at river mouths using measuring rods. A search revealed a patent application (application number 201720079160.9) disclosing a water level and flow velocity detection device, comprising a measuring rod; a metal box at the upper end of the measuring rod, and a water level sensor and a flow velocity sensor at the lower part of the measuring rod; a battery, a controller, and a GSM SMS module are housed inside the metal box; an angle sensor is installed on one outer surface of the metal box, with its detection end parallel to the vertical plane; an LCD screen is also installed on the other outer surface of the metal box; a solar panel is also installed on the upper surface of the metal box, and the solar panel is electrically connected to the battery; the water level sensor, flow velocity sensor, and angle sensor are all connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the LCD screen and the GSM SMS module, respectively; the GSM SMS module is connected to the mobile phone signal of the staff.

[0003] However, during actual use, the applicant found that the fixing rod on its flow velocity detection device, which is used to insert into the mud at the bottom of the estuary, cannot be folded and stored after the detection work is completed. This makes the detection device require a lot of space, which is inconvenient for staff to store and carry. In view of this, we propose a foldable estuary flow velocity measurement rod.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, this utility model provides a technical solution:

[0022] A foldable estuarine flow velocity measuring rod includes a measuring support rod 1. A housing 2 is fixedly connected to the upper end of the measuring support rod 1. A controller 21 is fixed inside the housing 2. A battery 22 is fixed inside the housing 2 below the controller 21. The controller 21 is electrically connected to the battery 22 via wires. A fixed rod 3 is rotatably connected to the lower end of the measuring support rod 1 via a hinge shaft 8. A flow velocity sensor 7 is fixedly installed on the outer wall of the lower end of the measuring support rod 1, away from the hinge shaft 8. The flow velocity sensor 7 is electrically connected to the controller 21 via wires. The controller 21 is equipped with a GSM SMS module, which is connected to the operator's mobile phone signal. An upper slot 11 is formed on the side wall of the measuring support rod 1, and a lower slot is formed on the side wall of the measuring support rod 1 below the upper slot 11. The measuring support rod 1 is elastically connected to a limiting rod 5 via a spring 6. A limiting plate 51 is fixedly installed on the limiting rod 5, with its bottom abutting against the bottom of the lower slot 12. The spring 6 is sleeved on the limiting rod 5, with its upper end abutting against the top of the lower slot 12 and its lower end abutting against the top of the limiting plate 51. A pull ring 52 is provided at the upper end of the limiting rod 5, which is located in the upper slot 11. The lower end of the limiting rod 5 is inserted into a limiting insertion hole 32 opened at the top of the fixing rod 3. A ground-inserting tip 4 is provided at the lower end of the fixing rod 3, and a threaded hole 31 is opened on the side wall of the lower end of the fixing rod 3. A locking bolt 9 is threadedly connected to the upper part of the measuring support rod 1, and the locking bolt 9 is threadedly engaged with the threaded hole 31. Pulling up the limiting rod 5 causes its lower end to move out of the limiting hole 32, allowing the fixing rod 3 to be folded upwards around the hinge shaft 8. The fixing rod 3 is then secured by screwing one end of the locking bolt 9 into the threaded hole 31. This reduces the space occupied by the estuary flow velocity measuring rod, making it easier for staff to store and carry. In use, first unscrew one end of the locking bolt 9 from the threaded hole 31, and manually pull upwards the pull ring 52 to move the lower end of the limiting rod 5 into the measuring support rod 1. The up-and-down movement of the limiting rod 5 causes the limiting plate 51 to move upwards, compressing the spring 6. Then, the fixing rod 3 can be rotated downwards around the hinge shaft 8 until it is coaxial with the measuring support rod 1. At this point, releasing the pull ring 52 allows the spring 6 to compress the rod. The lower end of the limiting rod 5 can be automatically inserted into the limiting hole 32 to lock the fixing rod 3. Then, the lower end of the ground-inserting rod 4 is inserted into the mud at the bottom of the estuary where the flow velocity is to be measured, fixing the fixing rod 3 and the measuring support rod 1 in the water. The flow velocity of the estuary can then be measured by the flow velocity sensor 7. The data measured by the flow velocity sensor 7 can be transmitted to the controller 21 and can be transmitted to the staff's mobile phone via the GSM SMS module on the controller 21. After the flow velocity measurement is completed, the pull ring 52 can be pulled upward again to move the lower end of the limiting rod 5 out of the limiting hole 32. The fixing rod 3 can then be folded upward around the hinge shaft 8. Finally, one end of the locking bolt 9 is manually screwed into the threaded hole 31 to fix the folded fixing rod 3.

[0023] The upper part of the ground-inserting tip 4 is slidably disposed in the fixed rod 3. A limit slider 34 is symmetrically disposed on the inner wall of the lower end of the fixed rod 3. A limit groove 41 is symmetrically opened on the side wall of the upper part of the ground-inserting tip 4. The limit slider 34 and the limit groove 41 are slidably engaged. A screw 10 is rotatably connected to the inside of the fixed rod 3 via a bearing. The lower end of the screw 10 is threaded into the threaded groove inside the ground-inserting tip 4. An adjusting head 101 is fixedly disposed on the upper end of the screw 10. An adjusting window 33 is opened on the fixed rod 3 below the limiting insertion hole 32. The adjusting head 101 is disposed in the adjusting window 33. By rotating the screw 10 clockwise, the ground-inserting tip 4 is moved downwards, thus adjusting the ground-inserting tip. The extended length of rod 4 allows for adjustment of the distance between the velocity sensor 7 and the riverbed, enabling the measurement of estuary flow velocity at different water levels. This enhances practicality. During estuary flow velocity measurement, the distance between the velocity sensor 7 and the riverbed can be adjusted according to measurement requirements. Adjustment can be achieved by manually rotating the adjusting head 101 clockwise to rotate the screw 10. The cooperation of the limiting slider 34 and the limiting groove 41 moves the insertion rod 4 downwards, adjusting its extended length and thus the distance between the velocity sensor 7 and the riverbed, thereby enabling the measurement of estuary flow velocity at different water levels.

[0024] Working principle: In use, first unscrew one end of the locking bolt 9 from the threaded hole 31, and manually pull the pull ring 52 upward to move the lower end of the limiting rod 5 into the measuring support rod 1. At this time, the up and down movement of the limiting rod 5 causes the limiting plate 51 to move upward, which can compress the spring 6. Then, the fixing rod 3 can be rotated downward around the hinge shaft 8 until it is coaxial with the measuring support rod 1. At this time, release the pull ring 52. Under the elastic force of the spring 6, the lower end of the limiting rod 5 can be automatically inserted into the limiting hole 32 to lock the fixing rod 3. Then, insert the lower end of the ground-inserting rod 4 into the mud at the bottom of the estuary where the flow velocity to be measured is to be fixed in the water. The flow velocity of the estuary can then be measured by the flow velocity sensor 7. The data measured by the flow velocity sensor 7 can be transmitted to the controller 21 and can be transmitted to the controller 21 via GSM short. The signal is transmitted to the staff's mobile phone. During the measurement of the estuary flow velocity, the distance between the flow velocity sensor 7 and the bottom of the estuary can be adjusted according to the measurement requirements. During adjustment, the screw 10 can be rotated clockwise by manually rotating the adjusting head 101 to rotate the screw 10. At this time, through the cooperation of the limiting slider 34 and the limiting groove 41, the insertion tip 4 can be moved downward to adjust the protrusion length of the insertion tip 4, thereby adjusting the distance between the flow velocity sensor 7 and the bottom of the estuary. This allows for the measurement of the estuary flow velocity at different water levels. After the flow velocity measurement is completed, the pull ring 52 can be pulled upward again to move the lower end of the limiting insertion rod 5 out of the limiting insertion hole 32. The fixing rod 3 can then be folded upward around the hinge shaft 8. Finally, one end of the locking bolt 9 can be manually screwed into the threaded hole 31 to fix the folded fixing rod 3.
