Description

Technical Field

[0001] The present application belongs to the technical field of flow detection equipment, and in particular relates to a flow detection device for a hydropower station. Background Art

[0002] The main characteristics of the flow rate of the turbine of a hydropower station are large flow rate and large diameter of the pressure steel pipe, which have very high requirements for the flow meter and measurement method. In actual use, the bypass detection method is adopted for flow detection, that is, by setting a bypass pipe on the main water pipe and setting a detection instrument at the bypass pipe with a flow corresponding relationship. This not only reduces the requirements for the detection equipment, but also greatly reduces the difficulty of detection.

[0003] The patent with publication number CN221006466U discloses a flow detection device for a hydropower station, including a pipe body, a flow detection meter and an assembly mechanism; the detection end of the flow detection meter is arranged in the pipe body; the assembly mechanism includes two main assembly rings, two auxiliary assembly rings, a plurality of clamping parts and a plurality of fastening parts; the two main assembly rings are connected to the two sides of the pipe body; the two auxiliary assembly rings are respectively connected to the first bypass pipe and the second bypass pipe, the first bypass pipe, the second bypass pipe and the pipe body are connected, and a plurality of connecting holes are provided on the main assembly ring and the auxiliary assembly ring; one of the clamping parts includes a movable shaft and a clamping block; the movable shaft is rotatably arranged on the main assembly ring, and one end of the clamping block is fixed on the movable shaft.

[0004] The above patent fixes and disassembles the first bypass pipe and the second bypass pipe by setting a fastening part and a locking part. Although it can achieve the effect of fastening and easy disassembly, after multiple actual disassemblies, the fastening nut in the fastening part is prone to damage itself and the assembly ring. In severe cases, it may lead to failure to fasten, and improvement is needed. Utility Model Content

[0005] The purpose of this application is to provide a flow detection device for a hydropower station that can solve the above problems.

[0006] The purpose of this application is to provide a flow detection device for a hydropower station, comprising:

[0007] The tube body includes a detection tube body and a first auxiliary tube body and a second auxiliary tube body provided on both sides of the detection tube body;

[0008] A flow detector is provided on the detection tube body;

[0009] A fixing mechanism, used for connecting the first auxiliary tube body and the second auxiliary tube body to two sides of the detection tube body;

[0010] In which, the fixing mechanism includes a first mounting ring and a second mounting ring arranged on both sides of the detection tube body, a third mounting ring arranged on the first auxiliary tube body and corresponding to the first mounting ring, a fourth mounting ring arranged on the second auxiliary tube body and corresponding to the second mounting ring, and a fastening structure connecting the first mounting ring, the third mounting ring, the second mounting ring and the fourth mounting ring.

[0011] The aforementioned hydropower station flow detection device utilizes the first, second, third, and fourth mounting rings, and their connection via a fastening structure, ensuring a secure connection between the detection tube body and the first and second auxiliary tube bodies. This not only improves the overall stability of the device but also helps prevent loosening or damage due to external factors or vibration. Furthermore, the design of the fastening structure allows the first and second auxiliary tube bodies to be conveniently connected to both sides of the detection tube body and easily disassembled when needed, facilitating routine maintenance, inspection, and replacement of the flow meter, thereby reducing maintenance costs and time.

[0012] The fastening structure prevents damage to the individual mounting rings during multiple disassembly processes, extending their service life and reducing replacement costs due to ring damage, while also ensuring the continued stable operation of the device. A flow meter installed on the detection tube accurately measures water flow. Accurate flow data helps better control and manage hydropower station operations and improve energy efficiency.

[0013] Furthermore, the fastening structure includes:

[0014] a sector-shaped mounting block, detachably mounted on the third mounting ring, wherein the sector-shaped mounting block is provided with a threaded hole;

[0015] a mating hole group, comprising a first through hole provided on the first mounting ring, a second through hole provided on the third mounting ring and communicating with the first through hole and the threaded hole, a third through hole provided on the third mounting ring, and a fourth through hole provided on the first mounting ring;

[0016] The fastening rod comprises a limiting head, a long rod body and a threaded head provided at the end of the long rod body;

[0017] The threaded head of the fastening rod passes through the fourth through hole, the third through hole, the second through hole, and the first through hole in sequence and then matches with the threaded hole.

[0018] The sector-shaped mounting block is removably attached to the third mounting ring, facilitating installation and removal. If the sector-shaped mounting block is damaged or needs replacement, it can be replaced individually without replacing the entire third mounting ring, reducing maintenance costs. The threaded holes on the sector-shaped mounting block also facilitate securing the fastening rod. The mating hole group includes multiple through-holes on the first and third mounting rings. These holes are designed to allow the fastening rod to pass through and connect the two mounting rings. The second and third through-holes not only connect to the first and fourth through-holes, but also allow the threaded head of the fastening rod to mate with the threaded holes on the sector-shaped mounting block after passing through these holes, achieving a secure connection while enhancing installation flexibility.

[0019] The fastening rod consists of three parts: a limit head, a long rod body and a threaded head. The design of the limit head can prevent the fastening rod from slipping during the tightening process. The long rod body provides sufficient length to ensure that the fastening rod can pass through all through holes and cooperate with the threaded holes. The design of the threaded head enables the fastening rod to be firmly fixed on the sector-shaped mounting block, thereby achieving a tight connection between the two mounting rings.

[0020] At the same time, since the fastening structure adopts the design of detachable fan-shaped mounting blocks and matching hole groups, as well as the multifunctional fastening rod, the entire device becomes very simple and convenient during installation and disassembly, which not only improves work efficiency, but also reduces the risks during installation and disassembly, and reduces the cost of replacement.

[0021] Further: the fastening structure also includes:

[0022] a groove, provided on the first mounting ring and recessed inwardly;

[0023] A mounting platform is arranged in the groove and protrudes outward, and a fifth through hole communicating with the fourth through hole is provided on the mounting platform;

[0024] The protective cover is arranged on the mounting platform, and the limit head of the fastening rod is in contact with the protective cover after the fastening rod is installed;

[0025] Wherein, the protective cover is provided with a sixth through hole for the long rod to pass through.

[0026] A groove in the first mounting ring accommodates the mounting platform, which protrudes outward and features a fifth through-hole. This not only makes the entire fastening structure more compact and aesthetically pleasing, but also helps enhance the stability of the connection. The fifth through-hole in the mounting platform connects to the fourth through-hole, providing a passage for the long rod of the fastening rod, ensuring it can smoothly pass through all necessary through-holes and ultimately engage with the threaded holes in the sector-shaped mounting block.

[0027] The protective cover provides support and protection for the stopper head of the fastening rod. The sixth through-hole in the protective cover allows the long rod to pass through, ensuring the proper installation and use of the fastening rod. Despite the relatively complex design of the fastening structure, the various components fit together very tightly and smoothly, making installation and maintenance much simpler and more efficient, reducing operational difficulty and time costs.

[0028] Furthermore, the diameter of the long rod is smaller than the first through hole, the second through hole, the third through hole, the fourth through hole and the fifth through hole, and the diameter of the long rod is the same as the sixth through hole.

[0029] The diameter of the long rod is smaller than the diameters of the first, second, third, fourth, and fifth through holes, ensuring that the long rod can easily pass through these through holes during installation without generating excessive friction with the hole walls. At the same time, the diameter of the long rod is the same as the diameter of the sixth through hole, so that when the fastening rod passes through all the through holes and finally mates with the threaded hole on the fan-shaped mounting block, the long rod will come into close contact with the sixth through hole, acting as a limiter. Since the long rod is not subject to wear when passing through other through holes, it can maintain its original size and shape when mating with the threaded hole, thereby effectively reducing the possibility of thread wear. By reducing the wear of the long rod during installation, the service life of the fastening structure is extended, eliminating the need for frequent replacement of the fastening structure or maintenance.

[0030] Furthermore, an isolation ring is provided in the first through hole, a seventh through hole for the long rod to pass through is provided in the center of the isolation ring, an auxiliary ring extending outward is provided on the outer wall of the long rod, and an elastic member is provided between the auxiliary ring and the isolation ring.

[0031] The isolating ring provided in the first through hole provides a stable passage for the long rod body, which helps to maintain the straightness of the long rod body and reduce friction and wear caused by bending or deflection during installation. The outward-extending auxiliary ring provided on the outer wall of the long rod body provides a support point for the installation of the elastic member. The elastic member is provided between the auxiliary ring and the isolating ring and can provide a pre-tightening force during the installation process, thereby enhancing the stability of the fastening structure and improving the reliability of the connection. At the same time, through the pre-tightening force of the elastic member, the fit between the long rod body and the threaded hole is tighter, thereby improving the firmness of the installation. In addition, the elastic force of the elastic member not only helps with pre-tightening during installation, but also provides a certain amount of auxiliary force during disassembly. When the fastening structure needs to be disassembled, the operator can use the elastic force of the elastic member to slightly push the long rod body, making it easier to unscrew it from the threaded hole, reducing the difficulty of disassembly and improving work efficiency.

[0032] Furthermore, the first mounting ring is provided with a first sealing cover adapted to the opening of the first through hole, and the third mounting ring is provided with a second sealing cover adapted to the opening of the third through hole. The first sealing cover and the second sealing cover are sleeved on the long rod body, and both are made of rubber material.

[0033] The first and second sealing covers are mounted on the first and third mounting rings, respectively, and fit over the openings of the first and third through-holes. These sealing covers effectively prevent external moisture, impurities, or gases from entering the through-holes, thereby improving the sealing performance of the entire fastening structure. The first and second sealing covers are made of rubber, a material with excellent elasticity and sealing properties. The rubber sealing covers fit tightly against the long rod, maintaining a stable seal even under pressure fluctuations or vibrations. Furthermore, the rubber material is wear-resistant and corrosion-resistant, extending the service life of the sealing covers.

[0034] The beneficial effects of this application are:

[0035] 1. The arrangement of the first, second, third, and fourth mounting rings, and the connection between them through the fastening structure, ensures a secure connection between the detection tube body and the first and second auxiliary tube bodies, which not only improves the overall stability of the device but also helps prevent loosening or damage caused by external factors or vibration.

[0036] 2. By setting up a fastening structure, each mounting ring can be protected from damage during multiple disassembly processes, thereby extending the service life of the mounting ring, reducing the replacement cost caused by damage to the mounting ring, and ensuring the continuous and stable operation of the device;

[0037] 3. By installing the flow meter on the detection pipe, the water flow rate can be accurately measured. Accurate flow data helps to better control and manage the operation of the hydropower station and improve energy utilization efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The flow detection device for a hydropower station provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0046] Example 1:

[0047] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a flow detection device for a hydropower station, comprising:

[0048] The tube body includes a detection tube body 100 and a first sub-tube body 110 and a second sub-tube body 120 provided on both sides of the detection tube body 100;

[0049] The flow meter 200 is provided on the detection tube body 100;

[0050] The fixing mechanism 300 is used to connect the first auxiliary tube body 110 and the second auxiliary tube body 120 to both sides of the detection tube body 100;

[0051] Among them, the fixing mechanism 300 includes a first mounting ring 310 and a second mounting ring 320 arranged on both sides of the detection tube body 100, a third mounting ring 330 arranged on the first auxiliary tube body 110 and corresponding to the first mounting ring 310, a fourth mounting ring 340 arranged on the second auxiliary tube body 120 and corresponding to the second mounting ring 320, and a fastening structure 400 connecting the first mounting ring 310, the third mounting ring 330, the second mounting ring 320 and the fourth mounting ring 340.

[0052] In some implementations of the embodiments of this application, Figure 1 As shown, the above-mentioned hydropower station flow detection device is used. Through the arrangement of the first mounting ring 310, the second mounting ring 320, the third mounting ring 330, and the fourth mounting ring 340, and the connection between them via the fastening structure 400, a stable connection between the detection tube body 100 and the first and second auxiliary tube bodies 110, 120 is ensured. This not only improves the overall stability of the device, but also helps prevent loosening or damage caused by external factors or vibration. At the same time, the design of the fastening structure 400 allows the first and second auxiliary tube bodies 110, 120 to be conveniently connected to both sides of the detection tube body 100 and can be easily disassembled when needed, facilitating daily maintenance, inspection, and replacement of the flow meter 200, thereby reducing maintenance costs and time.

[0053] By providing fastening structure 400, damage to each mounting ring is avoided during multiple disassembly processes, thereby extending the service life of the mounting rings, reducing replacement costs due to damaged mounting rings, and ensuring the continued stable operation of the device. Flow meter 200 is installed on detection tube body 100 to accurately measure the flow rate of the water flow. Accurate flow data helps to better control and manage the operation of the hydropower station and improve energy efficiency.

[0054] Example 2:

[0055] An embodiment of the present application provides a flow detection device for a hydropower station. In addition to the above-mentioned technical features, the flow detection device for a hydropower station in the embodiment of the present application also includes the following technical features.

[0056] like Figure 3 and Figure 4 As shown, the fastening structure 400 includes:

[0057] The fan-shaped mounting block 410 is detachably mounted on the third mounting ring 330 , and a threaded hole 411 is provided on the fan-shaped mounting block 410 ;

[0058] A mating hole group includes a first through hole 420 provided on the first mounting ring 310, a second through hole 421 provided on the third mounting ring 330 and communicating with the first through hole 420 and the threaded hole 411, a third through hole 422 provided on the third mounting ring 330, and a fourth through hole 423 provided on the first mounting ring 310;

[0059] The fastening rod 430 includes a limiting head 431, a long rod body 432, and a threaded head 433 provided at the end of the long rod body 432;

[0060] The threaded head 433 of the fastening rod 430 passes through the fourth through hole 423 , the third through hole 422 , the second through hole 421 , and the first through hole 420 in sequence and then matches with the threaded hole 411 .

[0061] In this embodiment, the sector-shaped mounting block 410 is detachably mounted on the third mounting ring 330. This not only facilitates installation and removal, but also allows for individual replacement of the sector-shaped mounting block 410 without having to replace the entire third mounting ring 330 if damaged, thereby reducing maintenance costs. Furthermore, the threaded holes 411 on the sector-shaped mounting block 410 facilitate the securement of the fastening rod 430. The mating hole group includes multiple through-holes on the first and third mounting rings 310, 330. These through-holes allow the fastening rod 430 to pass through and connect the two mounting rings. The second and third through-holes 421, 422 not only communicate with the first and fourth through-holes 420, 423, but also allow the threaded head 433 of the fastening rod 430 to mate with the threaded hole 411 on the sector-shaped mounting block 410 after passing through these holes, thereby achieving a secure connection and enhancing installation flexibility.

[0062] The fastening rod 430 includes three parts: a limit head 431, a long rod body 432 and a threaded head 433. The design of the limit head 431 can prevent the fastening rod 430 from slipping during the tightening process. The long rod body 432 provides sufficient length to ensure that the fastening rod 430 can pass through all through holes and cooperate with the threaded hole 411. The design of the threaded head 433 enables the fastening rod 430 to be firmly fixed on the fan-shaped mounting block 410, thereby achieving a tight connection between the two mounting rings.

[0063] At the same time, since the fastening structure 400 adopts the design of a detachable fan-shaped mounting block 410 and a matching hole group, as well as a multifunctional fastening rod 430, the entire device becomes very simple and convenient during installation and disassembly, which not only improves work efficiency, but also reduces the risks during installation and disassembly, and Huake Instrument reduces the cost of replacement.

[0064] Example 3:

[0065] An embodiment of the present application provides a flow detection device for a hydropower station. In addition to the above-mentioned technical features, the flow detection device for a hydropower station in the embodiment of the present application also includes the following technical features.

[0066] like Figure 3 and Figure 4 As shown, the fastening structure 400 further includes:

[0067] The groove 440 is provided on the first mounting ring 310 and is recessed therein;

[0068] The mounting platform 450 is disposed in the groove 440 and protrudes outward. The mounting platform 450 is provided with a fifth through hole 451 communicating with the fourth through hole 423;

[0069] The protective cover 460 is disposed on the mounting platform 450 , and after the fastening rod 430 is installed, its limit head 431 contacts the protective cover 460 ;

[0070] The protective cover 460 is provided with a sixth through hole 461 for the long rod 432 to pass through.

[0071] In this embodiment of the present application, the groove 440 provided on the first mounting ring 310 provides space for the mounting platform 450. The mounting platform 450 protrudes outward and is provided with a fifth through hole 451. This not only makes the entire fastening structure 400 more compact and aesthetically pleasing, but also helps to improve the stability of the connection. The fifth through hole 451 provided on the mounting platform 450 communicates with the fourth through hole 423, providing a passage for the long rod 432 of the fastening rod 430 to pass through, ensuring that the fastening rod 430 can smoothly pass through all necessary through holes and ultimately mate with the threaded hole 411 on the sector-shaped mounting block 410.

[0072] The protective cover 460 provides support and protection for the stopper 431 of the fastening rod 430. The sixth through hole 461 in the protective cover 460 is designed to allow the long rod 432 to pass through, ensuring the normal installation and use of the fastening rod 430. Although the design of the fastening structure 400 is relatively complex, the various components fit together very tightly and smoothly, making the installation and maintenance process simpler and more efficient, reducing operational difficulty and time costs.

[0073] Furthermore, the diameter of the long rod 432 is smaller than the first through hole 420 , the second through hole 421 , the third through hole 422 , the fourth through hole 423 and the fifth through hole 451 , and the diameter of the long rod 432 is the same as the diameter of the sixth through hole 461 .

[0074] The diameter of the long rod 432 is smaller than the diameters of the first through hole 420, the second through hole 421, the third through hole 422, the fourth through hole 423, and the fifth through hole 451, ensuring that the long rod 432 can easily pass through these through holes during installation without excessive friction with the hole walls. At the same time, the diameter of the long rod 432 is the same as the diameter of the sixth through hole 461, so that when the fastening rod 430 passes through all the through holes and finally mates with the threaded hole 411 on the fan-shaped mounting block 410, the long rod 432 will form close contact with the sixth through hole 461, acting as a stop. Because the long rod 432 is not worn when passing through the other through holes, it can maintain its original size and shape when mated with the threaded hole 411, effectively reducing the possibility of thread wear. By reducing wear on the long rod 432 during installation, the service life of the fastening structure 400 is extended, eliminating the need for frequent replacement or maintenance of the fastening structure 400.

[0075] Example 4:

[0076] An embodiment of the present application provides a flow detection device for a hydropower station. In addition to the above-mentioned technical features, the flow detection device for a hydropower station in the embodiment of the present application also includes the following technical features.

[0077] like Figure 3 and Figure 4 As shown, an isolation ring 500 is provided in the first through hole 420, and a seventh through hole 510 is provided in the center of the isolation ring 500 for the long rod body 432 to pass through. An auxiliary ring 520 extending outward is provided on the outer wall of the long rod body 432, and an elastic member 530 is provided between the auxiliary ring 520 and the isolation ring 500.

[0078] In the embodiment of the present application, the isolation ring 500 provided in the first through hole 420 provides a stable passage for the long rod 432, which helps maintain the straightness of the long rod 432 and reduces friction and wear caused by bending or deflection during installation. The outward-extending auxiliary ring 520 provided on the outer wall of the long rod 432 provides a support point for the installation of the elastic member 530. The elastic member 530 is provided between the auxiliary ring 520 and the isolation ring 500, and can provide a pre-tightening force during the installation process, thereby enhancing the stability of the fastening structure 400 and improving the reliability of the connection. At the same time, through the pre-tightening force of the elastic member 530, the fit between the long rod 432 and the threaded hole 411 is tighter, thereby improving the firmness of the installation. In addition, the elastic force of the elastic member 530 not only helps with pre-tightening during installation, but also provides a certain auxiliary force during disassembly. When the fastening structure 400 needs to be disassembled, the operator can use the elastic force of the elastic member 530 to slightly push the long rod body 432, making it easier to unscrew it from the threaded hole 411, reducing the difficulty of disassembly and improving work efficiency.

The first sealing cover 600 and the second sealing cover 610 are sleeved on the long rod body 432, and both are made of rubber material.

[0082] In the embodiment of the present application, the first sealing cover 600 and the second sealing cover 610 are respectively arranged on the first mounting ring 310 and the third mounting ring 330, and are adapted to the openings of the first through hole 420 and the third through hole 422. The sealing cover can effectively prevent external moisture, impurities or gas from entering the interior of the through hole, thereby improving the sealing performance of the entire fastening structure 400. The first sealing cover 600 and the second sealing cover 610 are made of rubber material, which has good elasticity and sealing performance. The rubber sealing cover can fit tightly on the long rod body 432 and maintain a stable sealing effect even in the presence of pressure changes or vibrations. In addition, the rubber material also has certain wear resistance and corrosion resistance, which can extend the service life of the sealing cover.
