Description

Technical Field

[0001] This utility model relates to the field of water conservancy testing technology, specifically a portable water flow velocity measuring device for water conservancy testing. Background Technology

[0002] A portable current meter is a device specifically designed for measuring the velocity and flow rate of water in hydrological monitoring, river flow monitoring, agricultural irrigation, municipal water supply and drainage, industrial wastewater, and water resources administration. It is widely used in water conservancy testing. The portable current meter adopts a special ultra-low power consumption design and fully digital signal processing technology, which makes the instrument measurement more stable and reliable, and has high measurement accuracy. It can be widely used in hydrology, water conservancy, agricultural irrigation, water supply and drainage and other occasions where frequent mobile measurement is required and there is no power supply on site.

[0003] In existing portable flow meters, the water flow drives the speed measuring paddle of the detection body to rotate. The detection body then transmits the rotation data of the speed measuring paddle to the display body as an electrical signal. However, due to the large lateral span of some fluids, it is difficult to place the detection body of the device in the middle of the fluid, which reduces the convenience of device placement and thus affects the practicality of the device.

[0004] Based on this, this utility model designs a portable water flow velocity measuring device for hydraulic testing to solve the above problems. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a portable water flow velocity measuring device for hydraulic testing, which has the following beneficial effects:

[0016] 1. This portable water flow velocity measuring device for water conservancy testing uses a guide steel cable to allow personnel to determine the testing range as needed. Once the testing range is determined, the guide steel cable moves along the adjustment hole on the limiting component. The guide steel cable then moves the testing body through the extension support. After the testing body moves to the testing range, it is inserted into the water body of the flow channel. This greatly enhances the adaptability of the device to different flow channels, effectively improves the convenience of device deployment, and thus enhances the practicality of the device.

[0017] 2. This portable water flow velocity measuring device for water conservancy testing uses a limiting component to insert a cross-shaped pin into the soil on both sides of the water conservancy channel. The cross-shaped pin fixes the limiting component through friction with the soil. Then, it drives the guide steel cable to move along the adjustment hole on the lifting support. After the detection body moves to the detection range, the adjustment bolt is rotated, and the adjustment bolt fixes the guide steel cable to the lifting support, which effectively improves the stability of the device during the detection process and thus enhances the applicability of the device.

[0018] 3. This portable water flow velocity measuring device for water conservancy testing moves the lifting support downward along the lifting circular rail, and the lifting support moves the extension support downward through the guide steel cable. The extension support then moves the detection body into the water body of the flow channel, effectively reducing the influence of the flowing water body during the device adjustment process and greatly reducing the probability of damage during the device adjustment process, thereby enhancing the practicality of the device.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3This utility model provides a technical solution: a portable water flow velocity measuring device for hydraulic testing, comprising a testing body 1 and a display body 2. An extension support 3 is fitted onto the outer surface of the testing body 1. Two sets of guide holes are opened on the right side of the extension support 3, and a guide steel cable 4 is inserted into the inner wall of each set of guide holes. Through the guide steel cable 4, personnel determine the testing range as needed. After the testing range is determined, the guide steel cable 4 moves along the adjustment hole on the limiting component 5. The guide steel cable 4 drives the testing body 1 to move through the extension support 3. After the testing body 1 moves to the testing range, it is inserted into the water body of the flow channel. This greatly enhances the adaptability of the device to different flow channels, effectively improves the convenience of device deployment, and thus enhances the practicality of the device. Two sets of limiting components 5 are set between the two sets of guide steel cables 4. Through the limiting components 5, cross-shaped pins 6 are inserted into the soil on both sides of the hydraulic flow channel. The cross-shaped pins 6 fix the limiting components 5 through friction with the soil. Then, the guide steel cable 4 moves along the adjustment hole on the lifting support 9. After the testing body 1 moves to the testing range, it rotates... Adjustable bolt 10 fixes the guide steel cable 4 to the lifting support 9, effectively improving the stability of the device during the testing process and thus enhancing the applicability of the device. Each set of limiting components 5 includes a cross pin 6, and each set of cross pin 6 has a bearing plate 7 at its top. Each set of bearing plate 7 has lifting rails 8 on both the front and rear sides of its top. Lifting supports 9 are slidably fitted between the outer surfaces of two adjacent sets of lifting rails 8. By driving the lifting supports 9 to move downward along the lifting rails 8, the lifting supports 9 pass through the guide steel cable 9. Cable 4 drives extension support 3 to move downward, and extension support 3 drives detection body 1 to insert into the water body of the flow channel, which effectively reduces the influence of flowing water during the device's distance adjustment process and greatly reduces the probability of damage during the device's distance adjustment process, thereby enhancing the practicality of the device. Each set of lifting supports 9 has two sets of distance adjustment holes on the right side for inserting guide steel cables 4. Each set of lifting supports 9 has two sets of distance adjustment bolts 10 threaded through its outer surface. The end of each set of distance adjustment bolts 10 inserted into the lifting support 9 is pressed against the outer surface of the corresponding guide steel cable 4.

[0025] In this utility model, in order to reduce the probability of the lifting support 9 disengaging from the lifting rail 8, a stroke screw 11 is provided at the top of each set of lifting rails 8, and a stroke nut 12 for limiting the stroke of the lifting support 9 is screwed onto the outer surface of each set of stroke screws 11, thereby reducing the probability of the lifting support 9 disengaging from the lifting rail 8.

[0026] In this utility model, in order to improve the stability of the device during operation, anti-loosening nuts 13 for applying pre-tightening force are screwed onto the outer surface of each set of adjusting bolts 10, reducing the probability of uncontrollable loosening of the adjusting bolts 10. The bottom end of each set of anti-loosening nuts 13 is pressed against the top of the corresponding lifting support 9, thereby improving the stability of the device during operation.

[0027] In this utility model, in order to improve the convenience of moving the guide steel cable 4, two sets of traction sleeves 14 are fitted on the outer surface of each set of guide steel cables 4, and traction crossbars 15 are provided between the two sets of adjacent traction sleeves 14. Through the traction sleeves 14 and traction crossbars 15, personnel can easily move the guide steel cable 4, thereby improving the convenience of moving the guide steel cable 4.

[0028] In this invention, in order to reduce the chance of the traction crossbar 15 slipping off the person's hand, an anti-slip handle 16 is fitted on the outer surface of each traction crossbar 15 to increase the friction between it and the person's hand. Multiple anti-slip grooves are provided on the outer surface of each anti-slip handle 16, thereby reducing the chance of the traction crossbar 15 slipping off the person's hand.

[0029] In this utility model, in order to extend the effective service life of the device, an anti-corrosion coating is provided on the outer surface of each set of guide steel cable 4, cross pin 6, bearing plate 7, lifting circular rail 8, lifting support 9, adjusting bolt 10 and extension support 3 to reduce their corrosion rate, thereby extending the effective service life of the device.

[0030] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0031] In use, first determine the detection range as needed. After the detection range is determined, insert the cross pin 6 into the soil on both sides of the water conservancy channel. The cross pin 6 fixes the limiting component 5 through the friction between it and the soil. Then, drive the guide cable 4 to move along the adjustment hole on the lifting support 9. The guide cable 4 drives the detection body 1 to move through the extension support 3. After the detection body 1 moves to the detection range, rotate the adjustment bolt 10. The adjustment bolt 10 fixes the guide cable 4 to the lifting support 9. Then, drive the lifting support 9 to move downward along the lifting circular rail 8. The lifting support 9 drives the extension support 3 to move downward through the guide cable 4. The extension support 3 drives the detection body 1 to be inserted into the water body of the channel. The detection body 1 detects the flow velocity of the water body in the channel. The detection body 1 transmits the flow velocity information to the display body 2 as an electrical signal. The display body 2 converts the electrical signal into relative unit data and transmits it to the personnel.
