Description

Technical Field

[0001] This utility model relates to the technical field of water flow velocity measurement devices, and in particular to a lifting support for an acoustic Doppler flow velocity measurement device. Background Technology

[0002] An acoustic Doppler current profiler is an instrument specifically designed to measure the velocity of water flow. It utilizes the acoustic Doppler effect, which states that the observed sound wave frequency changes when there is relative motion between the sound source and the observer. This effect can be used to accurately measure the velocity of water flow. The lifting support is the frame structure used to support the raising and lowering of the measuring mechanism.

[0003] The existing lifting support is formed by cutting and welding multiple steel pieces. The welded lifting support is large in size and weight, which is inconvenient to transport. Therefore, the existing lifting support requires the steel to be transported to the construction site first, then cut on site, and finally welded and assembled.

[0004] However, existing lifting supports have the following drawbacks: First, cutting and welding both require power, but construction sites are often located along rivers where power supply is difficult, making it difficult to meet the conditions for cutting and welding at the construction site; Second, lifting supports assembled by welding are difficult to disassemble, and when a part is damaged, the entire support must be replaced, resulting in high maintenance costs; Third, after testing at the current location, it is difficult to move the support to other locations for testing, and the water depth varies at different locations, requiring different heights for the lifting support, and the height of the lifting support after welding is not adjustable. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a lifting bracket for an acoustic Doppler flow velocity measuring device, which solves the problem of difficulty in power supply when welding the lifting bracket in the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is a lifting bracket for an acoustic Doppler flow velocity measuring device. The measuring device includes a measuring mechanism for measuring water flow velocity and a driving mechanism for driving the measuring mechanism to rise and fall. The lifting bracket includes:

[0007] A plurality of support units, wherein each support unit includes a plurality of longitudinal beams and a plurality of transverse beams, wherein the plurality of longitudinal beams are arranged in parallel and spaced apart, and a plurality of transverse beams are arranged between any two adjacent longitudinal beams, and the plurality of transverse beams are at the same height;

[0008] Multiple first connectors, each first connector having a first connecting portion and a second connecting portion fixed to each other, the first connecting portion being detachably connected to the outer side of the crossbeam, and the second connecting portion being detachably connected to both the outer side of the longitudinal beam and the outer side of another adjacent crossbeam.

[0009] A plurality of second connectors, each second connector having a third connector and a fourth connector fixed to each other, the third connector being detachably connected to the inner side of the crossbeam, and the fourth connector being detachably connected to the inner side of another adjacent crossbeam;

[0010] A chain guide rail is provided on the longitudinal beam, and a chain for pulling the measuring mechanism up and down is provided inside the chain guide rail.

[0011] Furthermore, the first connecting part, the second connecting part, the third connecting part and the fourth connecting part are all provided with a first fixing hole for connecting with the crossbeam;

[0012] The second connecting part has a second fixing hole for connecting with the longitudinal beam.

[0013] Furthermore, connection holes are provided on the crossbeam and the longitudinal beam;

[0014] The first fixing hole and the second fixing hole are threaded holes or through holes. The first connecting member is connected to the crossbeam / the longitudinal beam by screws, and the second connecting member is connected to the crossbeam by screws.

[0015] Furthermore, both the longitudinal beam and the transverse beam are arranged in the form of a cuboid, and the longitudinal beam has a first surface and a second surface on the outer side, and a third surface and a fourth surface on the inner side;

[0016] The first connecting portion is simultaneously attached to the first surface and the outer side of the crossbeam, and the second connecting portion is simultaneously attached to the second surface and the outer side of another adjacent crossbeam; the third surface and the fourth surface are respectively connected to two adjacent crossbeams.

[0017] Furthermore, four longitudinal beams are provided in the same support unit, and four transverse beams are provided at the same height, with any two adjacent transverse beams being perpendicular to each other.

[0018] Furthermore, the first connecting portion is perpendicular to the second connecting portion, and the third connecting portion is perpendicular to the fourth connecting portion.

[0019] Furthermore, the upper surfaces of the uppermost plurality of crossbeams are flush with the upper end surfaces of the longitudinal beams, so that the upper surfaces of the crossbeams and the upper end surfaces of the longitudinal beams form a mounting surface for mounting the drive mechanism.

[0020] Furthermore, the height of the lowermost plurality of crossbeams is higher than the lower end of the longitudinal beams.

[0021] Furthermore, it also includes a third connector, which includes a fifth connector and a sixth connector. The fifth connector is connected to the longitudinal beam of one of the support units, and the sixth connector is connected to the longitudinal beam of another adjacent support unit.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] (1) By setting multiple first connectors on the outer surfaces of the crossbeams and longitudinal beams, and setting second connectors on the inner surfaces of two adjacent crossbeams, multiple longitudinal beams and multiple crossbeams can be detachably assembled together. In this way, the original on-site welding of the lifting support is replaced, and the problem of welding being impossible due to the lack of power supply at the construction site is solved.

[0025] (2) Both the first and second connecting parts can be detachably connected to the crossbeam and the longitudinal beam, so that the crossbeam and the longitudinal beam can be arbitrarily disassembled. When some parts are corroded or bent, the damaged parts can be removed and replaced separately without replacing the entire lifting bracket, thus reducing maintenance costs.

[0026] (3) The crossbeam and longitudinal beam are detachable. After the current position test is completed, the lifting bracket can be removed and transported to the next position for assembly and testing, so as to realize the reuse of the lifting bracket.

[0027] (4) The height of the lifting bracket is adjustable. The height of the lifting bracket can be adjusted according to the water depth at different locations to ensure that the lifting bracket can be used in different scenarios and is more flexible. Attached Figure Description

Detailed Implementation

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] Please refer to Figures 1-4 This utility model discloses a lifting bracket for an acoustic Doppler flow velocity measuring device. The measuring device includes a measuring mechanism for measuring water flow velocity and a driving mechanism for driving the measuring mechanism to move up and down. The lifting bracket includes:

[0036] A plurality of support units, wherein the support unit includes a plurality of longitudinal beams 200 and a plurality of transverse beams 100, wherein the plurality of longitudinal beams 200 are arranged in parallel and spaced apart, and a plurality of transverse beams 100 are arranged between any two adjacent longitudinal beams 200, and the plurality of transverse beams 100 are at the same height;

[0037] Multiple first connectors 300, each first connector 300 having a first connecting portion 310 and a second connecting portion 320 fixed to each other, the first connecting portion 310 being detachably connected to the outer side of the crossbeam 100, and the second connecting portion 320 being detachably connected to both the outer side of the longitudinal beam 200 and the outer side of another adjacent crossbeam 100.

[0038] A plurality of second connectors 400, each second connector 400 having a third connecting portion 410 and a fourth connecting portion 420 fixed to each other, the third connecting portion 410 being detachably connected to the inner side of the crossbeam 100, and the fourth connecting portion 420 being detachably connected to the inner side of another adjacent crossbeam 100.

[0039] A chain guide rail 500 is provided on the longitudinal beam 200, and a chain for pulling the measuring mechanism up and down is provided inside the chain guide rail 500.

[0040] Specifically, in this application, multiple first connectors 300 are provided on the outer surfaces of the crossbeams 100 and longitudinal beams 200, and second connectors 400 are provided on the inner surfaces of two adjacent crossbeams 100, so that the multiple longitudinal beams 200 and multiple crossbeams 100 can be detachably assembled together. This replaces the original on-site welding of the lifting support, solving the problem of welding being impossible due to the lack of power supply at the construction site.

[0041] Meanwhile, since both the first connecting piece 300 and the second connecting piece 400 can be detachably connected to the crossbeam 100 and the longitudinal beam 200, the crossbeam 100 and the longitudinal beam 200 can be arbitrarily disassembled. When some parts are corroded or bent, the damaged parts can be removed and replaced separately without replacing the entire lifting bracket, thus reducing maintenance costs.

[0042] It should be noted that the detachability between the crossbeam 100 and the longitudinal beam 200 is achieved through the first connector 300 and the second connector 400. The first connector 300 and the second connector 400 can be connected to the crossbeam 100 and the longitudinal beam 200 by means of bolts, screws, clips, etc.

[0043] Furthermore, since the crossbeam 100 and the longitudinal beam 200 are detachable, after the test at the current position is completed, the lifting support can be removed and transported to the next position for assembly and testing, thus realizing the reuse of the lifting support.

[0044] Furthermore, a first covering plate 350 and a second covering plate 360 ​​are respectively provided on both sides of the first connecting portion 310 and the second connecting portion 320. The first covering plate 350 is connected to the upper side of the crossbeam 100, and the second covering plate 360 ​​is connected to the lower side of the crossbeam 100. That is, the first connecting member 300, the first covering plate 350, the second covering plate 360, and the second connecting member 400 can be connected to the four sides of the crossbeam 100 respectively and fixed to the longitudinal beam 200, making the structure between the crossbeam 100 and the longitudinal beam 200 more stable.

[0045] Furthermore, the first connecting part 310, the second connecting part 320, the third connecting part 410 and the fourth connecting part 420 are all provided with a first fixing hole 330 for connecting with the crossbeam 100;

[0046] The second connecting part 320 has a second fixing hole 340 for connecting with the longitudinal beam 200.

[0047] Furthermore, connection holes are provided on the crossbeam 100 and the longitudinal beam 200;

[0048] The first fixing hole 330 and the second fixing hole 340 are threaded holes or through holes. The first connecting member 300 is connected to the crossbeam 100 / the longitudinal beam 200 by screws, and the second connecting member 400 is connected to the crossbeam 100 by screws.

[0049] Specifically, both the first and second fixing holes are threaded holes, and a detachable connection can be achieved by screwing the screw into the first or second fixing hole and passing it through the connecting hole.

[0050] Of course, the first and second fixing holes can also be set as through holes. Nuts are riveted on both the first and second connectors. A detachable connection can be achieved by screwing the screw into the nut and passing it through the first or second fixing hole.

[0051] Furthermore, both the longitudinal beam 200 and the transverse beam 100 are arranged in the form of a cuboid. The longitudinal beam 200 has a first surface and a second surface on the outer side, and a third surface and a fourth surface on the inner side.

[0052] The first connecting part 310 is simultaneously attached to the first surface and the outer side of the crossbeam 100, and the second connecting part 320 is simultaneously attached to the second surface and the outer side of another adjacent crossbeam 100; the third surface and the fourth surface are respectively connected to two adjacent crossbeams 100.

[0053] Specifically, the first connecting part 310 is attached to the first surface and the outer side of the crossbeam 100, and the second connecting part 320 is attached to the second surface and the outer side of another adjacent crossbeam 100. This can increase the contact area between the first connecting part 300 and the crossbeam 100 and the longitudinal beam 200, thereby enhancing the stability of the lifting support structure and increasing its strength.

[0054] Furthermore, four longitudinal beams 200 are provided in the same support unit, and four transverse beams 100 are provided at the same height, with any two adjacent transverse beams 100 being perpendicular to each other.

[0055] Furthermore, the first connecting portion 310 is perpendicular to the second connecting portion 320, and the third connecting portion 410 is perpendicular to the fourth connecting portion 420.

[0056] Furthermore, the upper surfaces of the uppermost plurality of crossbeams 100 are flush with the upper end face of the longitudinal beam 200, so that the upper surfaces of the crossbeams 100 and the upper end face of the longitudinal beam 200 form a mounting surface for mounting the drive mechanism.

[0057] Specifically, the uppermost horizontal beam 100 and the upper end of the vertical beam 200 are at the same height, and their upper surfaces are flush, forming a flat surface. This flat surface can be used to install the drive mechanism, which is the mounting surface of the drive mechanism, so that the drive mechanism can be horizontally arranged above the lifting bracket.

[0058] Furthermore, the height of the lowermost plurality of crossbeams 100 is higher than the lower end of the longitudinal beam 200.

[0059] The bottommost crossbeam 100 is higher than the bottom of the longitudinal beam 200, so that the bottom of the entire lifting support only has the bottom ends of the four longitudinal beams 200, so that it can be placed on the uneven bottom surface and prevent the crossbeam 100 from interfering with the bottom surface, causing the bottom ends of the longitudinal beams 200 to be suspended and unable to bear the force.

[0060] Furthermore, it also includes a third connector, which includes a fifth connector and a sixth connector. The fifth connector is connected to the longitudinal beam 200 of one of the support units, and the sixth connector is connected to the longitudinal beam 200 of another adjacent support unit.

[0061] The height of the support unit in this application is adjustable. Specifically, the height of the entire lifting support can be increased by adding another support unit to the existing support unit. The two support units are connected by a third connector, that is, the fifth connecting part of the third connector is connected to the longitudinal beam 200 of one of the support units, and the sixth connecting part is connected to the longitudinal beam 200 of the other support unit.

[0062] Therefore, when the lifting support is moved to different locations for testing, the height of the lifting support can be adjusted according to the water depth at different locations, ensuring that the lifting support can be used in different scenarios and is more flexible.

[0063] It should be noted that the connection method of the third connector is the same as that of the first connector 300 / second connector 400.

[0064] Furthermore, it also includes a fourth connector, which includes the first connecting portion 310 and the second connecting portion 320, and a sixth connecting portion is provided above the first connecting portion 310 and the second connecting portion 320 respectively.

[0065] Specifically, when multiple lifting supports need to be connected, the first connection point is removed, and the third connector is replaced with a fourth connector. The fourth connector connects the horizontal and vertical beams 200 within the same support unit, as well as the vertical beams 200 between different support units. In other words, the fourth connector simultaneously achieves the functions of both the third and first connectors 300, making it more practical.

[0066] Furthermore, solar panels, radar level gauges, and equipment boxes can be installed at the crossbeam 100, making it more expandable.

[0067] It should be noted that since the outer shell of the measuring mechanism is made of plastic, during the dry season or when the water level is low, the measuring mechanism is directly exposed to the water surface, and long-term exposure to the sun can easily cause the outer shell to become brittle or even crack.

[0068] Based on this, this application provides a protective cover on the lifting support. During the dry season or when the water level is low, the measuring mechanism can be raised to be hidden inside the protective cover and its power supply can be cut off, thereby protecting the measuring mechanism.

[0069] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0070] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0071] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0072] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
