Description

Technical Field

[0001] This utility model relates to the technical field of water flow velocity monitoring equipment, specifically to a protective frame for a portable water flow velocity measuring instrument. Background Technology

[0002] Hydraulic flow velocity measurement is a technical means to calculate the distance water travels per unit time. It is used in fields such as water conservancy projects and hydrological monitoring, providing data support for water resource management and flood control and drought relief projects. In water conservancy projects and hydrological monitoring, hydraulic flow velocity measuring instruments are specialized instruments for measuring hydraulic flow velocity. They can use components such as ultrasonic waves, electromagnetic induction, or mechanical impellers to sense water flow velocity. They are portable, accurate, and real-time, and can adapt to the flow velocity monitoring needs of different water environments.

[0003] Existing technologies often have the following problems when used:

[0004] In fields such as water conservancy engineering and hydrological monitoring, portable hydraulic velocity measuring instruments with mechanical impellers are widely used for real-time measurement of water flow velocity. However, currently used portable hydraulic velocity measuring instruments with mechanical impellers lack effective protective mechanisms for their core component, the mechanical impeller, during actual use and storage. When transported or stored in an unused state, they are easily damaged by collisions or compression. Furthermore, the observation table used to observe specific flow velocity data is also inconvenient to securely store during transport, affecting the accuracy of hydraulic velocity measurement. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a protective frame for a portable hydraulic flow velocity measuring instrument, which can effectively solve the problems of the lack of an effective protective mechanism for mechanical impellers in the existing technology, which makes them easy to be damaged when not in use, and the observation table is also inconvenient to store, affecting the measurement accuracy of hydraulic flow velocity.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a protective frame for a portable hydraulic flow velocity measuring instrument, comprising:

[0008] A measuring frame and an observation table are provided. An impeller velocity meter is rotatably mounted on the lower part of the outer peripheral wall of the measuring frame. The impeller velocity meter is electrically connected to the observation table via wires.

[0009] A storage and protection assembly is used to protect the impeller flow meter. The storage and protection assembly includes a handle fixedly connected to the top of the measuring frame. The outer peripheral wall of the measuring frame has a threaded section, and a threaded sleeve is threadedly connected to the threaded section. A protective frame is fixedly connected to the lower end face of the threaded sleeve, and a protective base plate is fixedly connected to the lower end of the measuring frame.

[0010] A snap-fit ​​fixing component is fixedly connected to the lower part of the outer peripheral wall of the handle. The snap-fit ​​fixing component is used to snap and fix the observation table.

[0011] Furthermore, the storage and protection assembly also includes an electromagnet ring fixedly connected to the upper part of the outer peripheral wall of the measuring frame. The screw sleeve is made of low-carbon steel with a corrosion-resistant surface treatment. A control button is fixedly installed on the lower part of the outer peripheral wall of the handle. The control button is used to control the electromagnet ring to be energized and de-energized. When the electromagnet ring is energized, the electromagnet ring and the screw sleeve are set in opposite poles attracting each other.

[0012] Furthermore, the snap-fit ​​assembly includes a snap-fit ​​bracket fixedly connected to the outer peripheral wall of the handle, and a stop block and a nylon anti-slip pad are fixedly connected to the outer wall of the observation gauge. The snap-fit ​​bracket and the nylon anti-slip pad are selectively squeezed together.

[0013] Furthermore, both the protective frame and the protective base plate are designed with a hollow structure.

[0014] Furthermore, the outer peripheral wall of the threaded sleeve is fixedly connected with anti-slip vertical strips.

[0015] Furthermore, a rubber gasket is fixedly connected to the lower end of the protective frame, and the rubber gasket selectively presses against the protective base plate.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] This invention includes a storage and protection component. By pressing a control button, the electromagnet ring is de-energized, causing the screw sleeve to automatically descend and engage with the threaded section on the measuring frame. Then, by rotating the screw sleeve, the protective frame moves downward, allowing it to connect with the protective base plate. This allows the impeller velocity meter to be stored and protected using the protective frame and base plate, preventing damage to the impeller velocity meter when not in use and ensuring the accuracy of the impeller velocity meter's measurements.

[0018] This invention incorporates a snap-fit ​​fixing component, which connects the observation meter to the inside of the snap-fit ​​bracket. A stop block is used to limit the free fall of the observation meter, while the nylon anti-slip pad and the snap-fit ​​bracket work together to increase the frictional resistance of the observation meter relative to the inside of the bracket. This ensures the observation meter is securely fixed and stored, preventing damage when not in use and further ensuring the accuracy of the hydraulic flow velocity measurement.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: Refer to Figures 1 to 3 A protective frame for a portable hydraulic flow velocity measuring instrument includes: a measuring frame 1, an observation table 2, and a storage and protection assembly. An impeller flow velocity meter 3 is rotatably mounted on the lower part of the outer peripheral wall of the measuring frame 1. The impeller flow velocity meter 3 is electrically connected to the observation table 2 via a wire. The storage and protection assembly is used to protect the impeller flow velocity meter 3. The storage and protection assembly includes a handle 4 fixedly connected to the top of the measuring frame 1. A threaded section 5 is opened on the outer peripheral wall of the measuring frame 1. A threaded sleeve 6 is threadedly connected to the threaded section 5. A protective frame 7 is fixedly connected to the lower end of the threaded sleeve 6. A protective base plate 8 is fixedly connected to the lower end of the measuring frame 1.

[0027] Specifically, the outer peripheral wall of the screw sleeve 6 is fixedly connected with an anti-slip vertical strip 14. When the screw sleeve 6 is rotated to drive the protective frame 7 to move up and down relative to the measuring frame 1, the anti-slip vertical strip 14 can increase the friction of rotating the screw sleeve 6 to ensure that the screw sleeve 6 can smoothly engage with the threaded section 5.

[0028] The storage and protection components also include an electromagnet ring 9 fixedly connected to the upper part of the outer peripheral wall of the measuring frame 1, a screw sleeve 6 made of low carbon steel with corrosion-resistant surface treatment, and a control button 10 fixedly installed on the lower part of the outer peripheral wall of the handle 4. The control button 10 is used to control the electromagnet ring 9 to be energized and de-energized. When the electromagnet ring 9 is energized, the electromagnet ring 9 and the screw sleeve 6 are set to be attracted to each other with opposite poles.

[0029] Specifically, the screw sleeve 6 is made of low-carbon steel with a corrosion-resistant surface treatment. When the electromagnet ring 9 is energized, it can generate a magnetic attraction force on the screw sleeve 6. Furthermore, the surface of the screw sleeve 6 is treated with a corrosion-resistant coating, which can effectively prevent moisture corrosion and ensure long-term use.

[0030] Specifically, during the measurement of water flow velocity, the protective frame 7 can be moved upward by rotating the screw sleeve 6, and the electromagnet ring 9 can be energized by pressing the control button 10, so that the electromagnet ring 9 can generate a magnetic attraction relative to the screw sleeve 6, so as to fix the protective frame 7 and avoid affecting the flow velocity measurement operation of the impeller flow velocity meter 3.

[0031] Specifically, both the protective frame 7 and the protective base plate 8 adopt a hollow structure. When the impeller velocity meter 3 is stored and protected using the protective frame 7 and the protective base plate 8, the hollow structure can prevent the impeller velocity meter 3 from being in a closed space, allowing the water vapor adhering to the surface of the impeller velocity meter 3 to evaporate fully. A rubber gasket ring 15 is fixedly connected to the lower end of the protective frame 7. The rubber gasket ring 15 selectively presses against the protective base plate 8. When the protective frame 7 and the protective base plate 8 are connected, the rubber gasket ring 15 can reduce the collision force and pressing force between the lower end of the protective frame 7 and the protective base plate 8, which is conducive to maintaining the performance of the storage and protection components.

[0032] By pressing the control button 10 to de-energize the electromagnet ring 9, the screw sleeve 6 automatically descends and engages with the threaded section 5 on the measuring frame 1. Then, by rotating the screw sleeve 6, the protective frame 7 moves down, allowing the protective frame 7 to connect with the protective base plate 8. Thus, the protective frame 7 and the protective base plate 8 can be used to store and protect the impeller velocity meter 3, preventing damage to the impeller velocity meter 3 when it is not in use and ensuring the measurement accuracy of the impeller velocity meter 3.

[0033] A snap-fit ​​fixing component is fixedly connected to the lower part of the outer peripheral wall of the handle 4. The snap-fit ​​fixing component is used to snap-fit ​​and fix the observation table 2. The snap-fit ​​fixing component includes a snap-fit ​​bracket 11 fixedly connected to the outer peripheral wall of the handle 4. A stop block 12 and a nylon anti-slip pad 13 are fixedly connected to the outer wall of the observation table 2. The snap-fit ​​bracket 11 and the nylon anti-slip pad 13 are selectively squeezed together.

[0034] Specifically, the screen and buttons on the observation table 2 adopt an embedded structure, that is, when the observation table 2 is inside the card holder 11, the card holder 11 will not cause wear or accidental touch on the screen and buttons on the observation table 2.

[0035] The observation meter 2 is inserted into the inside of the clamping bracket 11. The abutment block 12 can stop and limit the free fall of the observation meter 2. At the same time, the nylon anti-slip pad 13 can be used to increase the frictional resistance of the observation meter 2 relative to the inside of the clamping bracket 11 by squeezing and cooperating with the clamping bracket 11. This allows for a full clamping, fixing and storage of the observation meter 2, preventing damage to the observation meter 2 when not in use, and further ensuring the accuracy of the measurement of hydraulic flow velocity.

[0036] The working principle of this utility model is as follows:

[0037] When in use, after the water flow velocity measurement is completed, the electromagnet ring 9 can be de-energized by pressing the control button 10, so that the screw sleeve 6 automatically descends and engages with the threaded section 5 on the measuring frame 1. Then, by rotating the screw sleeve 6, the protective frame 7 is moved down, so that the protective frame 7 is connected with the protective base plate 8. Thus, the impeller flow velocity meter 3 can be stored and protected by the protective frame 7 and the protective base plate 8.

[0038] After the water conservancy survey is completed, the observation table 2 can be connected to the inside of the clamping bracket 11. The abutment block 12 can be used to stop the free fall of the observation table 2. At the same time, the nylon anti-slip pad 13 can be used to increase the frictional resistance of the observation table 2 relative to the inside of the clamping bracket 11 by squeezing and cooperating with the clamping bracket 11, so as to fully clamp and fix the observation table 2 and store it.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
