[0001] The present application relates to the field of natural disasters caused by heavy rain, and in particular to a rainfall measuring device used for heavy rain disasters. Background Art

[0002] Rainfall is a common phenomenon. The detection of rainfall can be compared with the forecast data, which helps technicians to calibrate the rainfall forecast coefficient. At the same time, accurate monitoring of actual rainfall helps local resource statistics and allocation, and facilitates production guidance.

[0003] Commonly used rainfall detection methods outdoors include water level monitoring, pole-type rainfall monitoring, flow meter monitoring, siphon-type rainfall monitoring meter monitoring and tipping bucket rain gauge monitoring. The tipping bucket rain gauge is often used outdoors. This type of rain gauge has the characteristics of accurate rainfall monitoring and high sensitivity.

[0004] However, the tipping bucket rain gauge has a metering upper limit. When the rainfall exceeds the metering range of the rain gauge, the rain gauge cannot detect rainfall data and rainfall information. Summary of the invention

[0005] The present application provides a rainfall measuring device for rainstorm disasters, which is used to solve the problem that a rain gauge cannot monitor rainfall exceeding its maximum measuring range.

[0007] The rain gauge in this application can perform basic rainfall measurement. When the rain gauge reaches the maximum measurement value, the trigger component is controlled to move the cover plate, so that the upper opening of the rainstorm detection tube can receive rainwater, and the flow meter can measure the rainfall according to the amount of rainwater in the rainstorm detection tube, thereby making up for the problem that the existing outdoor rain gauge cannot measure rainstorm rainfall. The structure is simple and convenient, low cost, and easy to maintain, and can meet the requirements for collecting and monitoring rainstorm rainfall in meteorological data.

[0008] In some embodiments of the present application, the trigger assembly includes a power member and a transmission member, the power member is disposed in the base; the transmission member is in transmission connection with the power member, and the transmission member is in rotation connection with the cover plate, so that the cover plate rotates and opens the upper end opening of the rainstorm detection tube. The power member can generate mechanical displacement, and the mechanical displacement can be transmitted to the cover plate through the transmission member, so that the cover plate is opened or closed.

[0009] In some embodiments of the present application, the transmission member includes a support and a seesaw, the support is arranged on the base, and a rotating shaft is formed in the middle of the support; one end of the seesaw is fixedly connected to the cover plate, and the other end of the seesaw is transmission connected to the power member, and the middle part of the seesaw is rotatably connected to the rotating shaft on the support.

[0010] The support and the seesaw together can form a transmission structure similar to a seesaw, so that the power of the power part is transmitted through the seesaw, and the cover plate is rotated to make the cover plate rotate to open the upper end opening of the rainstorm detection tube.

[0011] In some embodiments of the present application, the trigger assembly also includes a traction rod, one end of which is transmission-connected to the output portion of the power member, the other end of which is rotationally connected to the end of the seesaw, and the other end of which is slidingly connected to the end of the seesaw along an extension direction of the seesaw.

[0012] The traction rod can play a transmission role. Compared with chain and rope transmission, the traction rod transmission is more precise. At the same time, the sliding and rotating connection between the traction plate and the seesaw can ensure that the traction rod can make the seesaw rotate around the support when performing linear or curved motion, thereby playing the role of transmitting the power of the power parts.

[0013] In some embodiments of the present application, a mounting hole is formed on the base, the power member is disposed in the mounting hole, and the traction rod is disposed in the mounting hole. The mounting hole can be used to mount the power member and the traction rod.

[0014] In some embodiments of the present application, the rainfall measuring device for rainstorm disasters further includes a sealing sleeve, which is arranged at the opening of the mounting hole, fixedly connected to the base, slidably connected to the traction rod, and sealedly connected to the traction rod.

[0015] In some embodiments of the present application, the trigger assembly also includes a compression spring; an annular mounting step is formed on the portion of the traction rod located in the mounting hole, an annular interference step is provided on the annular inner wall of the mounting hole and below the annular mounting step, and the compression spring is provided between the annular mounting step and the annular interference step.

[0016] The compression spring, the annular mounting step and the annular abutment step work together to achieve a resetting effect. When the amount of heavy rain does not exceed the range of the rain gauge by much, the device can be reused, and the cover plate can be reset by unloading the power member.

[0017] In some embodiments of the present application, the power element is a linear motor, which is small in size and easy to install, and can provide power that meets the needs of the device.

[0018] In some embodiments of the present application, the rainfall measuring device for rainstorm disasters further includes a rain collecting hopper, which is connected to the rainstorm detection tube and is arranged at the upper end opening of the rainstorm detection tube, and a cover plate is arranged on the rain collecting hopper. The rain collecting hopper can receive rainfall in a specified area, which helps to keep the rainfall in the rainstorm detection tube continuous, making the rainfall data measurement relatively more accurate.

[0019] In some embodiments of the present application, the rainfall measuring device for rainstorm disasters further includes a leakage net, which is arranged at the bottom opening of the rainstorm detection tube and is fixedly connected to the rainstorm detection tube.

[0028] Rainfall is a common phenomenon. The detection of rainfall can be compared with the forecast data, which helps technicians to calibrate the rainfall forecast coefficient. At the same time, accurate monitoring of actual rainfall helps local resource statistics and allocation, and facilitates production guidance.

[0029] Commonly used rainfall detection methods outdoors include water level monitoring, pole-type rainfall monitoring, flow meter monitoring, siphon-type rainfall monitoring meter monitoring and tipping bucket rain gauge monitoring. The tipping bucket rain gauge is often used outdoors. This type of rain gauge has the characteristics of accurate rainfall monitoring and high sensitivity.

[0030] However, the tipping bucket rain gauge has a metering upper limit. When the rainfall exceeds the metering range of the rain gauge, the rain gauge cannot detect rainfall data and rainfall information.

[0031] To do this, please refer to Figure 1 The present application provides a rainfall measuring device for rainstorm disasters, including a base 1, a rain gauge 2, a rainstorm detection tube 3, a flow meter 4, a cover plate 5 and a trigger assembly 6.

[0032] Please refer to Figure 1 The rain gauge 2 is arranged on the base 1. The rain gauge 2 may be a tipping bucket rain gauge 2, and a control element may be arranged in the rain gauge 2 to achieve a control effect. The control element may be a combination of a control circuit and a single chip microcomputer to achieve a control effect. The base 1 may be a metal base or a non-metal base. The base 1 should be fixedly arranged and maintain a high stability.

[0033] Please refer to Figure 1 The rain detection tube 3 is arranged on the base 1, the rain detection tube 3 is arranged vertically and has openings at both ends, and the rain detection tube 3 is spaced apart from the rain gauge 2. The rain detection tube 3 can be a plastic tube or a metal tube, and the rain detection tube 3 can be embedded in the base 1. Both ends of the rain detection tube 3 should be connected to air so that rainwater can flow in and be discharged smoothly.

[0034] Please refer to Figure 1 , the flow meter 4 is arranged in the rainstorm detection tube 3. The flow meter 4 can be a liquid flow meter 4. When the flow meter 4 is used outdoors with the rainstorm detection tube 3 to directly detect the rainfall, data deviation will occur. Therefore, the rainfall data detected by this solution has a low accuracy and can only serve as a reference auxiliary effect.

[0035] Please refer to Figure 1 The cover plate 5 is disposed on the upper opening of the rainstorm detection tube 3, and the cover plate 5 is disposed in contact with the upper end surface of the rainstorm detection tube 3. The cover plate 5 may be a metal plate, and the cover plate 5 should be larger than the upper opening of the rainstorm detection tube 3. When a rain collecting hopper is provided on the rainstorm detection tube 3, the area of ​​the cover plate 5 may be larger than the opening of the rain collecting hopper.

[0036] Please refer to Figure 1 The trigger assembly 6 is electrically connected to the rain gauge 2, and the trigger assembly 6 is connected to the cover plate 5, so that the trigger assembly 6 opens the cover plate 5. The trigger assembly 6 is used to receive the signal of the rain gauge 2 and open the cover plate 5. The trigger assembly 6 can be a pure mechanical structure or a mechanical and electronic combined structure.

[0037] Please refer to Figure 1 The rain gauge 2 in the present application can perform basic rain gauge 2 measurement. When the rain gauge 2 reaches the maximum measurement value, the trigger component 6 is controlled to move the cover plate 5, so that the upper end opening of the rainstorm detection tube 3 can receive rainwater, and the flow meter 4 can measure the rainfall according to the amount of rainwater in the rainstorm detection tube 3, thereby making up for the problem that the existing outdoor rain gauge 2 cannot measure rainstorm. The structure is simple and convenient, low in cost, and easy to maintain, and can meet the requirements for collecting and monitoring rainstorm rainfall in meteorological data.

[0038] In some examples, when the trigger assembly 6 drives the cover plate 5 to move, the cover plate 5 can be rotated, or the cover plate 5 can be slid in a horizontal direction to open the upper end opening of the rainstorm detection tube 3.

[0039] When the cover plate 5 rotates, the rotation angle of the cover plate 5 can be greater than 60°, so that the upper end opening of the rainstorm detection tube 3 can have a certain effective detection area; when the cover plate 5 slides in the horizontal direction, the horizontal sliding distance of the cover plate 5 can be greater than 60% of the diameter of the rainstorm detection tube 3, so that the upper end opening of the rainstorm detection tube 3 can have a certain effective detection area.

[0040] Please refer to Figure 1 In some examples, the trigger assembly 6 includes a power member 61 and a transmission member 62, the power member 61 is disposed in the base 1; the transmission member 62 is transmission-connected to the power member 61, and the transmission member 62 is rotationally connected to the cover plate 5, so that the cover plate 5 rotates and opens the upper end opening of the rainstorm detection tube 3. The power member 61 can generate mechanical displacement, and the mechanical displacement can be transmitted to the cover plate 5 through the transmission member 62, so that the cover plate 5 is opened or closed.

[0041] In some examples, the power member 61 and the transmission member 62 may be transmitted via a rope, a chain, or a rod.

[0042] Please refer to Figure 1 In some examples, the transmission member 62 includes a support 621 and a rocker 622, the support 621 is arranged on the base 1, and a rotating shaft is formed in the middle of the support 621; one end of the rocker 622 is fixedly connected to the cover plate 5, and the other end of the rocker 622 is transmission-connected to the power member 61, and the middle part of the rocker 622 is rotationally connected to the rotating shaft on the support 621.

[0043] The support 621 and the seesaw 622 can together form a transmission structure similar to a seesaw, so that the power of the power member 61 is transmitted through the seesaw 622, and the cover plate 5 is rotated to make the cover plate 5 rotate to open the upper end opening of the rainstorm detection tube 3.

[0044] Please refer to Figure 1 In some examples, the support 621 and the rocker 622 can be made of the same material as the base 1, the support 621 can be integrally formed with the base 1 or welded, and the rocker 622 can be a plate body or a rod body.

[0045] Please refer to Figure 1 In some examples, a force lever may be formed between the rocker plate 622 and the support 621 to achieve a larger angle of rotation of the cover plate 5 through a smaller displacement of the power member 61 .

[0046] Please refer to Figure 1In some examples, the trigger assembly 6 also includes a traction rod 623, one end of which is transmission-connected to the output portion of the power member 61, the other end of the traction rod 623 is rotationally connected to the end of the rocker 622, and the other end of the traction rod 623 is slidingly connected to the end of the rocker 622 along the extension direction of the rocker 622.

[0047] The traction rod 623 can play a transmission role. Compared with the chain and rope transmission, the traction rod 623 has a more precise transmission. At the same time, the sliding and rotating connection between the traction plate and the rocker 622 can ensure that the traction rod 623 can make the rocker 622 rotate around the support 621 when performing linear motion or curved motion, thereby playing the role of transmitting the power of the power part 61.

[0048] In some examples, the traction rod 623 may be a metal rod, and its material needs to be a hard material.

[0049] The rotational connection between the traction rod 623 and the rocker 622 can be achieved through a hinge, or can also be achieved through a rotating shaft; the sliding between the traction rod 623 and the rocker 622 can be achieved by setting the hinge as a sliding structure, that is, a sliding groove is set on the rocker 622 so that the hinge can slide along the extension direction of the rocker 622, and the hinge is connected to the traction rod 623 at the same time.

[0050] At this time, the linear motion of the end of the traction rod 623 in the vertical direction can be adjusted to the curved motion of the end of the seesaw 622, and the cover plate 5 at the other end of the seesaw 622 can be driven to rotate, thereby opening the upper end opening of the rainstorm detection tube 3.

[0051] Alternatively, the traction rod 623 may also be configured as a flexible rod or a rope, which may also achieve a corresponding traction effect.

[0052] Please refer to Figure 1 In some examples, a mounting hole 11 is formed on the base 1, the power member 61 is disposed in the mounting hole 11, and the traction rod 623 is disposed in the mounting hole 11. The mounting hole 11 can be used to mount the power member 61 and the traction rod 623.

[0053] Please refer to Figure 1 In some examples, the mounting hole 11 may be a square countersunk hole, a circular countersunk hole, or a hole of other shapes.

[0054] Please refer to Figure 1 In some examples, the rainfall measuring device for rainstorm disasters further includes a sealing sleeve 12, which is disposed at the opening of the mounting hole 11, is fixedly connected to the base 1, is slidably connected to the traction rod 623, and is sealed to the traction rod 623. The sealing sleeve 12 can seal the mounting hole 11 to prevent water from entering the power part 61, thereby protecting the power part 61.

[0055] Please refer to Figure 1 In some examples, the sealing sleeve 12 mainly plays a role of sealing and waterproofing, so the sealing sleeve 12 can be made of rubber or plastic.

[0056] Please refer to Figure 1 In some examples, the trigger assembly 6 also includes a compression spring 7; an annular mounting step is formed on the portion of the traction rod 623 located in the mounting hole 11, an annular interference step is provided on the annular inner wall of the mounting hole 11 and below the annular mounting step, and the compression spring 7 is provided between the annular mounting step and the annular interference step.

[0057] The compression spring 7, the annular mounting step and the annular abutment step work together to achieve a reset effect. When the rainfall in a rainstorm does not exceed the range of the rain gauge 2 by a large amount, the device can be reused. At this time, the cover plate 5 can be reset by unloading the force on the power member 61.

[0058] Please refer to Figure 1 In some examples, the compression spring 7 can provide a thrust, and the relative position of the annular interference step and the traction rod 623 is fixed by the thrust of the compression spring 7, thereby maintaining the position of the cover plate 5 at normal times; when resetting is required, the thrust spring can also be used to achieve a resetting effect.

[0059] Alternatively, a tension spring may be used, in which case the spring may be fixedly connected to both the annular interference step and the annular mounting step, and the annular interference step may be disposed above the annular mounting step, so that the rocker 622 may be reset by the tension of the tension spring.

[0060] Please refer to Figure 1 In some examples, the power member 61 is a linear motor. The linear motor is small in size and easy to install, and can provide power that meets the needs of the device.

[0061] Please refer to Figure 1 In some examples, the power member 61 may also be a hydraulic power motor or a curve motor, and only the corresponding movable space of the traction rod 623 needs to be set to meet the normal transmission of the traction rod 623.

[0062] Please refer to Figure 1 In some examples, the rainfall measuring device for rainstorm disasters further includes a rain collecting hopper 31, which is connected to the rainstorm detection tube 3 and is arranged at the upper end opening of the rainstorm detection tube 3, and the cover plate 5 is covered on the rain collecting hopper 31. The rain collecting hopper 31 can receive the rainfall in the designated area, which helps to keep the rainfall in the rainstorm detection tube 3 continuous, so that the rainfall data can be measured more accurately.

[0063] Please refer to Figure 1In some examples, the rain collecting hopper 31 and the rainstorm detection tube 3 can be fixedly connected, and the connection method can be clamping, welding or bonding. The rain collecting hopper 31 can be made of metal or plastic.

[0064] Please refer to Figure 1 In some examples, the rainfall measuring device for rainstorm disasters further includes a leakage net 32, which is arranged at the bottom opening of the rainstorm detection tube 3 and is fixedly connected to the rainstorm detection tube 3. The leakage net 32 ​​can prevent animals from entering the rainstorm detection tube 3 from the bottom opening of the rainstorm detection tube 3.

[0065] In some examples, the leakage mesh 32 may be a metal leakage mesh 32 to increase the strength of the leakage mesh 32 and prevent damage caused by high-speed water flow impact.

[0066] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0067] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
