Description

Technical Field

[0001] This utility model relates to the field of underwater measurement technology, and in particular to a water depth measuring device with underwater protection function. Background Technology

[0002] In many fields, such as surveying and bridge construction, it is necessary to measure the water depth of rivers and the topographic data of riverbeds. To achieve water depth measurement and riverbed topography measurement, it is often necessary to extend ultrasonic probes underwater.

[0003] When an ultrasonic probe is submerged underwater, the probe and the support on which it is mounted are subjected to the impact of the water flow. In environments with fast-flowing water, the impact of the water flow may directly damage the precision probe or twist the support on which the probe is mounted, thus affecting the underwater measurement of the ultrasonic probe. Utility Model Content

[0004] This invention provides a water depth measuring device with underwater protection function, which reduces the impact of water flow on the probe and mounting bracket during measurement, and better protects the probe.

[0005] This utility model provides a water depth measuring device with underwater protection function, comprising:

[0006] The main body is used to place on a measuring platform above the riverbed;

[0007] A first connector, connected to the main body, the lower end of the first connector extending underwater and connected to a first probe; and

[0008] The second connector is connected to the main body and is spaced apart from the first connector. The lower end of the second connector extends underwater and is connected to a flow disruptor. The flow disruptor is located on the incoming flow side of the first probe and is used to disrupt the water flow towards the first probe to reduce the impact of the water flow on the first connector and the first probe.

[0009] In one embodiment, the arrangement direction of the first connector and the second connector coincides with the water flow direction of the river to be measured, and the second connector is located on the inflow side of the first connector.

[0010] In one embodiment, the disturbance element is located underwater, and the top surface of the disturbance element is higher than the top surface of the first probe.

[0011] In one embodiment, the flow disruptor has a first flow guiding side and a second flow guiding side symmetrical along a first straight line, the first straight line extending along the water flow direction, and the distance between the first flow guiding side and the second flow guiding side gradually increases with the water flow direction to divert the water flow.

[0012] In one embodiment, the main body is provided with a vertically extending first slide groove, the first connector is slidably installed in the first slide groove, and the main body is also provided with a first threaded hole communicating with the first slide groove. A first screw is inserted into the first threaded hole, and the first screw is used to abut against the first connector to lock or unlock the first connector.

[0013] In one embodiment, the main body is provided with a vertically extending second slide groove, the second connector is slidably installed in the second slide groove, and the main body is also provided with a second threaded hole communicating with the second slide groove. A second screw is inserted into the second threaded hole, and the second screw is used to abut against the second connector to lock or unlock the second connector.

[0014] In one embodiment, the main body is further connected to a third connector, the lower end of which is fitted with a second probe, which is located above the water surface.

[0015] In one embodiment, the second probe is located on the incoming flow side of the disturbance to detect the river surface undisturbed by the disturbance.

[0016] In one embodiment, the first probe is an ultrasonic probe.

[0017] In one embodiment, rollers are mounted on the bottom of the body.

[0018] Compared with the prior art, the advantages of this utility model are that, since the main body is equipped with a first connector and a second connector, and the first connector and the second connector are spaced apart, the vibration on the first connector will not be transmitted to the second connector. Furthermore, a water-delaying device is installed at the lower end of the second connector, which is located on the incoming flow side of the first probe. The water-delaying device can turbulent the fluid flowing towards the first probe, slow down the flow rate of the fluid, thereby reducing the impact of the fluid on the first probe and the first connector, and extending the service life of the first probe.

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] In related technologies, probes are often submerged in water to measure underwater topography. This results in the probe itself and the support on which it is mounted being subjected to the impact of water currents while measuring the underwater topography, thus shortening the probe's lifespan.

[0035] To address the aforementioned technical problems, embodiments of this utility model provide a water depth measurement device with underwater protection function, comprising: a main body 100, which is placed on a measuring bridge spanning a riverbed. A first connecting member 210 and a second connecting member 310 are installed on the main body 100 at intervals. The lower end of the first connecting member 210 extends into the water and is equipped with a first probe 220, enabling the measurement of underwater topography using the submerged first probe 220.

[0036] The lower end of the second connector 310 also extends into the water, and a flow disruptor 320 is installed at the lower end of the second connector 310. The flow disruptor 320 is located on the incoming flow side of the first probe 220. The flow disruptor 320 can interfere with the water flow on the incoming flow side of the first probe 220, thereby reducing the velocity of the water flow impacting the first probe 220 and achieving underwater protection for the first probe 220.

[0037] For details, please refer to Figures 1 to 3 As shown, when measuring the underwater environment, the main body 100 of this water depth measuring device can be placed on the measuring platform 900, and the first connector 210 and the second connector 310 connected to the main body 100 can be extended out of the measuring platform 900, so that the lower ends of the first connector 210 and the second connector 310 extend into the water, thereby enabling the first probe 220 at the lower end of the first connector 210 to measure the underwater environment, while the flow-disrupting member 320 at the lower end of the second connector 310 can interfere with the water flow to reduce the flow velocity.

[0038] It is understandable that the angle of the main body 100 can be adjusted so that the flow-disrupting element 320 is located on the incoming flow side of the first probe 220. For example, if the water flow direction in 1 is from right to left, the angle of the main body 100 can be adjusted so that the flow-disrupting element 320 is located on the right side of the first probe 220. This will cause the water flow to be slowed down by the interference of the flow-disrupting element 320 before flowing to the first probe 220, thereby reducing the impact of the water flow at the first probe 220.

[0039] In this application, the components mainly subjected to water flow impact are the second connector 310 and the flow-disrupting component 320 installed at the lower end of the second connector 310. The first connector 210 is spaced apart from the second connector 310, so that the impact on the second connector 310 is basically not transmitted to the first connector 210 or the first probe 220, thus protecting the first probe 220. This enables the first probe 220 to adapt to underwater measurements in turbulent rivers and extends the underwater measurement life of the first probe 220.

[0040] Moreover, due to the turbulence effect of the turbulence-disrupting component 320, the water flow velocity towards the first connector 210 can be reduced. While protecting the first probe 220, it also prevents the first connector 210 from bending excessively due to water flow impact, so that the first probe 220 can be kept in the preset position. This avoids changes in the measurement area of ​​the first probe 220 due to bending deformation of the first connector 210, thereby improving the measurement accuracy of the first probe 220.

[0041] In this embodiment, the measurement platform 900 can be a measuring bridge spanning the river, a measuring boat floating on the water, or a measuring support erected on the water surface, as long as the main body 100 is located above the river surface and the lower ends of the first connecting member 210 and the second connecting member 310 can extend into the underwater platform.

[0042] See Figure 1 , Figure 4 as well as Figure 5 As shown, in some implementations, the arrangement direction of the first connector 210 and the second connector 310 coincides with the water flow direction of the river to be measured, and the second connector 310 is located on the incoming side of the first connector 210. For example, if the water flow direction is from west to east, the first connector 210 needs to be arranged due east of the second connector 310 so that the first connector 210 is located within the disturbance area formed by the second connector 310 and the disturbance member 320.

[0043] It is understandable that the distance between the first probe 220 and the flow-disrupting element 320 in the direction of water flow should be as small as possible, and the preferred distance between them in the direction of water flow is A (see...). Figure 4 As shown), where A≤15cm, to avoid the first probe 220 being located outside the turbulence area due to the first probe 220 being too far away from the turbulence component 320.

[0044] In some implementations, in order to determine the direction of water flow in the river to be measured, a floating strip can be placed on the surface of the river, and the direction of water flow in the river can be determined based on the direction of the floating strip.

[0045] See Figure 1 as well as Figure 6As shown, in some implementations, the flow disruptor 320 is located underwater, and the top surface of the flow disruptor 320 is higher than the top surface of the first probe 220. As is known in the art, due to the presence of many foreign objects on the riverbed, the water flow velocity is significantly affected, resulting in a faster flow velocity at the surface than at the bottom. In this application, because the top surface of the flow disruptor 320 is higher, it can slow down the high-speed water flow near the surface, thereby better protecting the first connector 210 and the first probe 220. In this application, the first probe 220 is located below the flow disruptor 320. In other implementations, the height dimension of the flow disruptor 320 can be increased, enabling it to disrupt the water flow at the surface as well as in deep water areas, thus better protecting the first probe 220.

[0046] Understandably, it is necessary to avoid setting the spoiler 320 too high, which would prevent it from protecting the first probe 220. Specifically, the height difference B between the bottom surface of the first probe 220 and the bottom surface of the spoiler 320 (see...) Figure 4 (As shown) The flow rate is controlled to B≤5cm so that the turbulence element 320 can slow down the fluid flow rate at the first probe 220.

[0047] See Figure 1 as well as Figure 5 As shown, in some implementations, the flow disruptor 320 has a first flow guiding side 321 and a second flow guiding side 322 that are symmetrical along a first straight line. The first straight line extends along the water flow direction, and the distance between the first flow guiding side 321 and the second flow guiding side 322 gradually increases with the water flow direction to divert the water flow.

[0048] When water flows toward the turbulence-disrupting component 320, part of the water flows along the first guide side 321, while another part flows along the second guide side 322. Because the distance between the first guide side 321 and the second guide side 322 increases along the direction of water flow, the two water flows will move away from each other, thereby significantly reducing the rapid water flow in the rear area of ​​the turbulence-disrupting component 320 and achieving the effect of turbulence.

[0049] In some implementations, the first probe 220 is also symmetrical along a first straight line, and the maximum distance between the first guide side 321 and the second guide side 322 is greater than the width of the first probe 220. This ensures that the first probe 220 is located within the turbulence region formed by the turbulence side 320.

[0050] In some implementations, the first guide side 321 and the incoming flow side of the second guide side 322 are connected to form a sharp-angle structure, which can more smoothly separate the water flow. In other implementations, the incoming flow sides of the first guide side 321 and the second guide side 322 can also be connected by a circular curved surface or a plane transition, and it is not necessarily necessary to form a sharp-angle structure.

[0051] Of course, in other implementations, the flow deflector 320 can also be configured as a flat plate structure, an arc-shaped plate structure, or other structures that obstruct water flow. The key is to reduce the water flow speed.

[0052] In some implementations, the flow-disrupting element 320 is detachably connected to the second connecting element 310 via a snap-fit ​​structure. Different shapes or sizes of flow-disrupting elements 320 can be used at the lower end of the second connecting element 310 to achieve flow disturbance in corresponding water flow environments. For example, a wider flow-disrupting element 320 can be used in turbulent water environments to enhance its flow-disrupting effect, while a narrower element can be used in relatively calm water environments to reduce the impact of water flow on the flow-disrupting element 320.

[0053] See Figure 1 , Figure 2 as well as Figure 4 As shown, in some implementations, the main body 100 is provided with a vertically extending first slide groove 130, the first connector 210 is slidably installed in the first slide groove 130, and the main body 100 is also provided with a first threaded hole communicating with the first slide groove 130. A first screw 510 is inserted into the first threaded hole, and the first screw 510 is used to abut against the first connector 210 to lock or unlock the first connector 210.

[0054] During use, the first connector 210 can be locked or unlocked by turning the first screw 510. When the first screw 510 is unscrewed from the first threaded hole, unlocking the first connector 210, the first connector 210 can be moved up and down along the first slide groove 130, thereby adjusting the height of the first probe 220 to ensure that the first probe 220 can be inserted underwater. In some implementations, a scale can be set on the first connector 210 so that the user can read the height difference between the first probe 220 and the top surface of the main body 100, thus facilitating the calculation of the depth of the underwater riverbed by combining the measurement results of the first probe 220 and the height difference between the first probe 220 and the top surface of the main body 100.

[0055] See Figure 2 as well as Figure 5As shown, the main body 100 includes a first protrusion 110 extending horizontally from the measuring platform 900, and a first groove 130 is formed at the first protrusion 110 so that the first connector 210 installed at the first groove 130 can extend underwater without being interfered with by the measuring platform 900.

[0056] See Figure 1 , Figure 2 as well as Figure 4 As shown, in some implementations, the main body 100 is also provided with a vertically extending second slide groove 140, the second connector 310 is slidably installed in the second slide groove 140, and the main body 100 is also provided with a second threaded hole communicating with the second slide groove 140. A second screw 520 is inserted into the second threaded hole, and the second screw 520 is used to abut against the second connector 310 to lock or unlock the second connector 310.

[0057] When it is necessary to adjust the height of the lower spoiler 320 of the second connector 310, the second screw 520 can be unscrewed from the second threaded hole to unlock the second connector 310. Then, the second connector 310 can be slid along the second slide groove 140 to adjust its height. To more accurately control the height of the second connector 310, a scale line can be set on the second connector 310. The height of the second connector 310 can be determined by reading the scale line.

[0058] Since the water flow will impact the turbulence-disrupting component 320, in order to prevent the turbulence-disrupting component 320 from hitting the second probe 420 under impact, an L-shaped second connector 310 will be used to make the turbulence-disrupting component 320 and the second probe 420 staggered in the direction of water flow.

[0059] See Figure 1 , Figure 2 as well as Figure 4 As shown, in some implementations, the main body 100 is also connected to a third connector 410, and a second probe 420 is installed at the lower end of the third connector 410. The second probe 420 is located above the water surface. The height difference between the water surface and the main body 100 can be measured through the second probe 420. By combining the height difference between the first probe 220 and the second probe 420, as well as the height difference between the riverbed and the first probe 220 measured by the first probe 220, the height from the river surface to the riverbed can be obtained.

[0060] See Figure 6 As shown, the calculation formula can be referenced as H=L1+(X-L2), where H is the height from the river surface to the riverbed, L1 is the height difference between the first probe 220 and the riverbed as measured by the first probe 220, X is the height difference between the first probe 220 and the second probe 420, and L2 is the height difference between the second probe 420 and the water surface as measured by the second probe 420.

[0061] L1 and L2 can be obtained directly from the measurement data fed back by the probe, while X can be measured in advance or obtained from the downward movement distance of the first connector 210 and the downward movement distance of the third connector 410.

[0062] In some implementations, the main body 100 is provided with a second protrusion 120 on the side away from the first protrusion 110, which can extend horizontally out of the measuring platform 900. A third groove 150 is formed on the second protrusion 120, and a third connector 410 is slidably installed in the third groove 150. The height of the second probe 420 can be adjusted by sliding the third connector 410 so that the second probe 420 is located above the water surface. The first connector 210 is detachably installed in the first groove 130, the second connector 310 is detachably installed in the second groove 140, and the third connector 410 is detachably installed in the third groove 150. In use, the first connector 210, the second connector 310, and the third connector 410 can be separated from the main body 100, so that the main body 100 can be placed on the measuring platform 900 and the first protrusion 110 and the second protrusion 120 can extend horizontally out of the measuring platform 900. Then install the first connector 210, the second connector 310 and the third connector 410 into the corresponding slide grooves.

[0063] See Figure 1 as well as Figure 5 As shown, in some implementations, the second probe 420 is located on the incoming flow side of the flow disruptor 320 to detect the river surface undisturbed by the flow disruptor 320. It is understandable that when the water flow impacts the second connector 310 and the flow disruptor 320, some splashing will be generated. If the water surface at the flow disruptor 320 is measured directly, the large splashing will affect the measurement accuracy. However, measuring the water surface undisturbed by the flow disruptor 320 can achieve higher measurement accuracy.

[0064] In some implementations, the first probe 220 is an ultrasonic probe, which can be used to conveniently measure the depth of the riverbed. Furthermore, compared to laser measurement, it is almost unaffected by light, and measurements can be performed even in deep water areas where light cannot reach.

[0065] In some implementations, the second probe 420 is also an ultrasonic probe.

[0066] See Figures 1 to 3 As shown, in some implementations, rollers 160 are installed at the bottom of the main body 100. Due to the rollers 160, the position of the main body 100 on the measurement platform 900 can be easily adjusted, thereby enabling measurements of different areas of the riverbed.

[0067] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
