Description

Technical Field

[0001] The utility model relates to the technical field of hydrological flow measurement, and more specifically to a portable hydrological flow measurement device. Background Art

[0002] With the development of technology and innovation, modern, automated, Internet of Things, and diversified devices have gradually entered various industries. In recent years, as the country's management of water resources has become stricter, the measurement of different forms of surface water such as irrigation water, industrial water, and river runoff during the flood season has become increasingly important, and the demand for flow monitoring of surface water by water conservancy and related departments has increased.

[0003] The portable hydrological velocity and flow meter meets the national open channel measurement standard and is developed specifically for hydrological measurement and flow velocity and flow measurement of farmland irrigation workers. It can be used for the measurement and calculation of the flow velocity and flow of various open channels and the flow of pump stations. The complete set of instruments consists of a highly sensitive propeller flow velocity meter, a 4×0.4m measuring rod, and a TYJ-2 hydrological flow velocity measuring instrument, and is placed in an aluminum alloy instrument box with dimensions of 47×37×12.

[0004] After retrieval, a portable hydrological emergency flow measurement device disclosed in the patent with the publication number CN218724366U includes a water flow detector. A storage mechanism and a limiting mechanism are respectively arranged on the top of the water flow detector, a connecting wire is welded to the outer wall of the top of the water flow detector, and a detection rod is welded to one end of the connecting wire.

[0005] The above technical solution has certain beneficial effects. During the carrying process, the whole is usually placed inside the box body, and there is sponge padding inside the box body to protect the measurement components. However, in the actual use process, a large amount of filled sponge will make the space inside the box body not fully utilized. At the same time, when located near the upper and lower surfaces of the box body, there is no additional protection structure, and it is easy for the box body to be deformed when impacted, causing damage to the flow measurement components. Therefore, we propose a portable hydrological flow measurement device. Summary of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a portable hydrological flow measurement device to solve the problems existing in the above background art.

[0007] The present utility model provides the following technical solution: A portable hydrological flow measurement device, including a first box body and a second box body, which are connected by hinges between the first box body and the second box body. Measuring tool bodies are loaded inside the first box body and the second box body. A lifting handle is provided in the middle of the front end of the first box body. Connecting buckles are provided at the front ends of the first box body and the second box body. Fixed guiding and limiting blocks are symmetrically provided inside the first box body and the second box body.

[0008] Further, a connecting pull block is provided on the surface of the active protection mechanism located inside the second box body, and a fixed limiting mechanism is fixedly connected to the surface of the second box body.

[0009] Further, the active protection mechanism includes a mounting spring, one end of the mounting spring is fixedly connected to a connecting protective cover block, and a measuring tool placement groove is provided on the surface of the connecting protective cover block.

[0010] Further, the outer surface of the end of the connecting protective cover block is slidably fitted with the inner side of the fixed guiding and limiting block.

[0011] Further, the fixed limiting mechanism includes a connecting sleeve block, fixed guide grooves are symmetrically provided on the surface of the connecting sleeve block, a force-bearing spring is fixedly connected to one end inside the connecting sleeve block, the other end of the force-bearing spring is fixedly connected to a moving mounting plate, a connecting positioning insertion rod is provided on the side of the moving mounting plate away from the force-bearing spring, a connecting pull arm is provided on the outer edge of the moving mounting plate, and one end of the connecting pull arm is fixedly connected to a connecting pull ring.

[0012] Further, the outer surface of the end of the connecting pull arm away from the connecting pull ring is slidably fitted with the inner side of the fixed guide groove.

[0013] Further, a pressure-receiving inclined surface is provided at the end of the connecting positioning insertion rod away from the moving mounting plate.

[0014] The technical effects and advantages of the present utility model:

[0015] 1. By providing the fixed guiding and limiting blocks and the active protection mechanism in the present utility model, when the first box body and the second box body are in a closed state, it can stably protect the measuring tool body, and at the same time, the internal space of the first box body and the second box body can be reasonably planned.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the drawings in the present utility model. In addition, the forms of the respective structures described in the following embodiments are merely examples, and the present utility model is not limited to the respective structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0024] Refer to Figures 1-5, the present utility model provides a portable hydrological flow measurement device, which includes a first box body 1 and a second box body 2. The first box body 1 and the second box body 2 are connected by hinges. The inner sides of the first box body 1 and the second box body 2 are loaded with a flow measurement tool body 20. A lifting handle 3 is provided in the middle of the front end of the first box body 1. Connection buckles 4 are provided at the front ends of the first box body 1 and the second box body 2. Fixed guiding and limiting blocks 5 are symmetrically provided on the inner sides of the first box body 1 and the second box body 2. Moving protection mechanisms 6 are provided on the inner sides of the first box body 1 and the second box body 2;

[0025] Among them, a connection pull block 7 is provided on the surface of the moving protection mechanism 6 located inside the second box body 2, and a fixed limiting mechanism 8 is fixedly connected to the surface of the second box body 2.

[0026] Among them, the moving protection mechanism 6 includes a mounting spring 9. One end of the mounting spring 9 is fixedly connected to a connection protective cover block 10. A flow measurement tool placement groove 11 is provided on the surface of the connection protective cover block 10, so that the flow measurement tool body 20 can be placed inside the flow measurement tool placement groove 11. The tool is wrapped by the connection protective cover block 10, thereby providing protection for the tool. At the same time, when the first box body 1 and the second box body 2 are collided by an external force, buffer treatment can be carried out through the stress expansion and contraction of the fixed guiding and limiting blocks 5, and the operation is convenient.

[0027] Among them, the outer side of the end surface of the connection protective cover block 10 is slidably fitted with the inner side of the fixed guiding and limiting block 5, so that when collided by an external force, the inertia generated by the gravity of the connection protective cover block 10 enables it to move stably inside the fixed guiding and limiting block 5, and the operation is convenient.

[0028] Among them, the fixed limiting mechanism 8 includes a connection sleeve block 12. Fixed guide grooves 13 are symmetrically provided on the surface of the connection sleeve block 12. One end of the inner side of the connection sleeve block 12 is fixedly connected to a stress spring 14. The other end of the stress spring 14 is fixedly connected to a moving mounting plate 15. A connection positioning insertion rod 16 is provided on the side of the moving mounting plate 15 away from the stress spring 14. A connection pull arm 17 is provided on the outer side of the edge of the moving mounting plate 15. One end of the connection pull arm 17 is fixedly connected to a connection pull ring 18, which is convenient for pulling the connection pull ring 18 to drive the connection pull arm 17, the moving mounting plate 15 and the connection positioning insertion rod 16 to move, compress the stress spring 14, and thus adjust quickly, and the use is convenient.

[0029] Among them, the outer side of the end surface of the connection pull arm 17 away from the connection pull ring 18 is slidably fitted with the inner side of the fixed guide groove 13, so that the end of the connection pull arm 17 can move stably inside the fixed guide groove 13, and the operation is convenient.

[0030] Wherein, a pressure-receiving inclined surface 19 is provided at one end of the connecting positioning plug rod 16 away from the moving mounting plate 15, facilitating the edge of the connecting pull block 7 to squeeze the pressure-receiving inclined surface 19 when the connecting pull block 7 moves, enabling the connecting positioning plug rod 16 to move by itself, which is convenient for operation.

[0031] The working principle of the present utility model: During use, when the first box body 1 and the second box body 2 are collided during carrying, the inertia generated by the weight of the connecting protective cover block 10 and the flow measurement tool body 20 can move, causing the mounting spring 9 to expand and contract, thereby buffering and providing protection for the flow measurement tool body 20. When the flow measurement tool body 20 needs to be taken or stored, first, the connecting pull block 7 needs to be lifted, driving the connecting protective cover block 10 located inside the second box body 2 to move, compressing the mounting spring 9. When the connecting pull block 7 moves, the edge of the connecting pull block 7 can squeeze the pressure-receiving inclined surface 19, enabling the connecting positioning plug rod 16 to move by itself, driving the moving mounting plate 15, the connecting pull arm 17, and the connecting pull ring 18 to move, compressing the force-bearing spring 14. After the connecting pull block 7 is adjusted, when the moving mounting plate 15 is acted upon by the force-bearing spring 14, it can drive the connecting positioning plug rod 16 to reset, enabling the connecting positioning plug rod 16 to insert into the inside of the connecting pull block 7. At this time, the connecting protective cover block 10 located inside the second box body 2 does not contact the flow measurement tool body 20. Open the second box body 2 to take and use the flow measurement tool body 20, or close the second box body 2. At this time, the connecting protective cover block 10 located inside the second box body 2 is above the flow measurement tool body 20. Then, pull the connecting pull ring 18, driving the connecting pull arm 17, the moving mounting plate 15, and the connecting positioning plug rod 16 to move, compressing the force-bearing spring 14, so as to quickly adjust. At this time, the connecting protective cover block 10 resets by itself under the action of the mounting spring 9, enabling the connecting protective cover block 10 to cover the outer surface of the flow measurement tool body 20, providing wrapping protection for the flow measurement tool body 20. The overall structure is simple, and the operation is convenient and fast.
