Description

Technical Field

[0001] The present invention relates to the technical field of precipitation measurement, and in particular to a portable precipitation measuring device. Background Art

[0002] With the growing demand for meteorological monitoring and the increasing need for rapid precipitation data acquisition in outdoor and emergency scenarios, traditional fixed rain gauges are limited by their fixed installation locations, bulky size, and high maintenance costs, making them difficult to meet the requirements of mobile monitoring, temporary deployment, and resource-constrained environments. Against this backdrop, portable precipitation measurement devices have emerged. By integrating microsensors, lightweight structural designs, and wireless data transmission technology, they enable portable and instant precipitation measurement, providing more flexible and efficient data collection solutions for meteorological disaster warning, agricultural irrigation management, and hydrological environment monitoring.

[0003] Although some existing portable precipitation measuring devices can measure precipitation to a certain extent, after collecting rainwater, the rainwater will evaporate due to heat, causing the amount of collected rainwater to change, resulting in inaccurate measurement results.

[0004] In summary, after some existing portable precipitation measuring devices complete the collection of rainwater, the problem of inaccurate measurement results caused by the evaporation of rainwater due to heat has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a portable precipitation measuring device. Summary of the Invention

[0005] To solve the above problems, the present invention provides a convenient precipitation measuring device. Through the coordinated work of the filtering component and the cooling component, the storage temperature of rainwater is lowered while reducing interference from external impurities, thereby reducing temperature fluctuations, reducing the amount of heat evaporation of the collected rainwater, and ensuring the accuracy of precipitation data.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable precipitation measurement device comprising a collection frame, the bottom of which is fixedly connected to and communicates with a processing tube, the bottom of which is fixedly connected to a fixed tube. The device also includes a controller, a cooling assembly provided on the bottom wall of the processing tube for cooling the processing tube, and a drive assembly provided within the processing tube for driving the cooling assembly.

[0007] A filter assembly for filtering impurities in rainwater is provided in the treatment cylinder, and a disturbance assembly for periodically disturbing the filter assembly is provided on the treatment cylinder. The filter assembly is located above the drive assembly, and the disturbance assembly is located above the cooling assembly.

[0008] A protection component for protecting the internal structure of the fixed cylinder is provided in the fixed cylinder, and the protection component is located below the driving component.

[0009] The technical principles of the above scheme are as follows:

[0010] The staff installs the device in the predetermined position through the fixed cylinder, reduces the possibility of impurities entering the fixed cylinder through the protective component, and controls the operation of the driving component through the controller. The driving component drives the cooling component to operate and cool the treatment cylinder.

[0011] When rainwater falls into the device, the filter assembly filters out impurities, reducing their impact on the amount of rainwater collected. During this process, the cooling assembly drives the disturbance assembly, causing it to periodically disturb the filter assembly, improving its filtration efficiency.

[0012] The above scheme has the following beneficial effects:

[0013] 1. The present invention, through the coordinated work of the filtering component and the cooling component, reduces the interference of external impurities while lowering the storage temperature of rainwater, thereby reducing temperature fluctuations, reducing the amount of heat evaporation of the collected rainwater, and ensuring the accuracy of precipitation data.

[0014] 2. The present invention disturbs the filter assembly through the disturbance assembly, so that the filter assembly can be cleaned under the disturbance action of the disturbance assembly, thereby extending the service life of the device and reducing the frequency of manual maintenance.

[0015] 3. The present invention protects the interior of the fixed tube through a protective component, thereby improving the weather resistance of the device and making the device more suitable for complex environments such as outdoor and field environments.

[0016] Furthermore, the cooling component includes several piston boxes fixedly connected to the inner bottom wall of the treatment cylinder, the inner side walls of the piston boxes are laterally slidingly fitted with piston plates, one side of the piston plates is fixedly connected to a piston rod, the end of the piston rod away from the piston plate passes through the adjacent piston box side wall and extends to the outside of the piston box where it is fixedly connected to a hinged plate, the top and bottom of adjacent hinged plates are hinged with hinged rods, and the hinged rods located in the same horizontal plane form a parallelogram structure.

[0017] The top of the piston box is provided with an air blowing hole, and the bottom of the piston box is connected with an air intake one-way valve, and the piston box is connected with the interior of the fixed cylinder through the air intake one-way valve.

[0018] Beneficial effect: During the reciprocating motion of the piston plate, gas will enter the piston box through the air inlet one-way valve and be discharged through the air blowing hole, thereby cooling the treatment cylinder and reducing the evaporation of rainwater caused by heat.

[0019] Furthermore, the driving assembly includes a driving member fixedly connected to the bottom wall of the processing cylinder, the controller is used to control the rotation of the output shaft of the driving member, a rotating plate is fixedly connected to the output shaft of the driving member, and the hinged plates are all located in the movement path of the rotating plate.

[0020] Beneficial Effects: The rotating plate is fixedly connected to the output shaft of the driver and rotates with the output shaft. Because the hinge plate is located within the rotating plate's motion path, when the rotating plate rotates and contacts the hinge plate, it pushes the hinge plate to move laterally. This design allows the hinge plate's movement to precisely track the rotating plate's trajectory, achieving precise drive of the piston plate and ensuring stability and reliability during the cooling process.

[0021] Furthermore, the filter assembly includes a filter plate fixedly connected to the inner wall of the treatment cylinder. The inner wall of the treatment cylinder is fixedly connected with a partition plate, which is located below the filter plate. A collection chamber is formed between the partition plate and the filter plate.

[0022] Beneficial effect: The filter plate can effectively block impurities in rainwater. As the filtration process proceeds, the impurities will be blocked above the filter plate and will not be mixed into the filtered rainwater, thus ensuring the quality of the filtered rainwater.

[0023] Furthermore, the disturbance component includes a disturbance cylinder fixedly connected to the outer wall of the treatment cylinder, a plurality of disturbance holes are circumferentially opened on the upper side wall of the treatment cylinder, and the disturbance holes are all located above the filter plate. A plurality of air inlet holes are circumferentially opened on the lower side wall of the treatment cylinder, and the piston boxes are connected to the disturbance cylinder through the air inlet holes adjacent to them, and the disturbance cylinder is connected to the inside of the treatment cylinder through the disturbance holes.

[0024] Beneficial Effects: When the gas in the piston box enters the disturbance cylinder through the air inlet, it is connected to the interior of the treatment cylinder through the disturbance hole. Gas is ejected from the disturbance hole, creating a localized turbulent airflow within the treatment cylinder. This turbulent airflow disturbs impurities on the filter plate surface, preventing them from clogging. Furthermore, because the disturbance cylinder is located on the outer wall of the treatment cylinder, the airflow within it also cools the treatment cylinder, reducing rainwater evaporation.

[0025] Furthermore, the protection component includes a porous baffle fixedly connected to the inner side wall of the fixed cylinder.

[0026] Beneficial effect: When the gas in the fixed cylinder enters the treatment cylinder, impurities in the gas will be intercepted by the porous baffle, thereby preventing the impurities from entering the interior of the treatment cylinder and causing wear and damage to the treatment cylinder.

[0027] Furthermore, a liquid level sensor is fixedly connected to the inner side wall of the collection chamber, and the controller is electrically connected to the staff terminal. The controller is used to receive the liquid level information collected by the liquid level sensor and send the liquid level information to the staff terminal.

[0028] Beneficial Effects: The liquid level sensor can accurately collect liquid level information in the collection chamber in real time. This information is promptly sent to the staff terminal through the controller, allowing staff to monitor the accumulation of liquid in the collection chamber at any time without having to check on site, thus improving work efficiency.

[0029] Furthermore, a rubber layer is fixedly connected to the piston plate.

[0030] Beneficial effect: The piston plate will undergo slight deformation during movement, and the rubber layer can change its shape accordingly with the deformation of the piston plate, so that it always maintains good sealing contact.

[0031] Furthermore, the disturbance holes are all fixedly connected with filter screens.

[0032] Beneficial effect: The design of the filter effectively prevents impurities from clogging the disturbance holes, ensures the smooth flow of the disturbance holes, and enables the gas to smoothly pass through the disturbance holes into the treatment cylinder, forming the required disturbed airflow.

[0033] Furthermore, the collecting frame is in an inverted cone shape.

[0034] Beneficial effect: The inverted cone-shaped collection frame can expand the scope of rainwater collection. When rainwater enters the collection frame, its inverted cone design can accommodate more rainwater, increasing the chance of rainwater collection.

[0035] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is further described in detail through specific implementation methods:

[0042] Example 1:

[0043] As attached Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The device shows a portable precipitation measurement device, comprising an inverted conical collection frame 1, welded to the bottom of which is a processing tube 2, which is integrally formed with a fixing tube 3. The device also includes a controller, a cooling assembly for cooling the processing tube 2, and a drive assembly for operating the cooling assembly.

[0044] The cooling assembly includes several piston boxes 4 welded to the inner bottom wall of the treatment cylinder 2. The inner side walls of the piston boxes 4 are laterally slidably fitted with piston plates 5. A rubber layer is bonded to the piston plates 5. A piston rod 6 is welded to one side of the piston plates 5. The end of the piston rod 6 away from the piston plate 5 passes through the adjacent side wall of the piston box 4 and extends to the outside of the piston box 4 to be integrally formed with a hinged plate 7. The top and bottom of the adjacent hinged plates 7 are hinged with hinged rods 8, and the hinged rods 8 located on the same horizontal plane form a parallelogram structure.

[0045] The top of the piston box 4 is provided with an air blowing hole, and the bottom of the piston box 4 is connected to an air intake one-way valve. The piston box 4 is connected to the interior of the fixed cylinder 3 through the air intake one-way valve.

[0046] The drive assembly includes a drive member bolted to the inner bottom wall of the treatment cylinder 2. A controller is used to control the rotation of the output shaft of the drive member. A rotating plate 9 is bolted to the output shaft of the drive member. The hinged plates 7 are located in the motion path of the rotating plate 9. In this embodiment, the drive member is a stepper motor.

[0047] A filter assembly for filtering impurities in rainwater is provided in the treatment cylinder 2, and a disturbance assembly for periodically disturbing the filter assembly is provided on the treatment cylinder 2. The filter assembly is located above the drive assembly, and the disturbance assembly is located above the cooling assembly.

[0048] The filter assembly includes a filter plate 10 welded to the inner wall of the treatment cylinder 2. The inner wall of the treatment cylinder 2 is integrally formed with a partition 11, which is located below the filter plate 10. A collection chamber is formed between the partition 11 and the filter plate 10. A liquid level sensor is fixedly connected to the inner wall of the collection chamber with screws, and the controller is electrically connected to the staff terminal. The controller is used to receive the liquid level information collected by the liquid level sensor and send the liquid level information to the staff terminal.

[0049] The disturbance assembly includes a disturbance cylinder 12 welded to the outer wall of the treatment cylinder 2. Several disturbance holes are opened circumferentially on the upper side wall of the treatment cylinder 2. The disturbance holes are all located above the filter plate 10. Several air inlet holes are opened circumferentially on the lower side wall of the treatment cylinder 2. The piston box 4 is connected to the disturbance cylinder 12 through the air inlet holes adjacent to it, and the disturbance cylinder 12 is connected to the inside of the treatment cylinder 2 through the disturbance holes.

[0050] A protection assembly for protecting the internal structure of the fixed cylinder 3 is provided in the fixed cylinder 3 . The protection assembly is located below the driving assembly and includes a porous baffle 13 welded to the inner wall of the fixed cylinder 3 .

[0051] The specific implementation process is as follows: after determining the installation point of the device, the staff installs the device at the predetermined position through the fixing tube 3, so that the fixing tube 3 is buried inside the soil, and then controls the stepper motor output shaft to rotate through the controller.

[0052] The output shaft of the stepper motor drives the rotating plate 9 to rotate during the rotation process. Thanks to the parallelogram structure design of the hinged rod 8, the rotating plate 9 will drive the adjacent hinged plate 7 to move back and forth laterally during the rotation process, which in turn drives the piston rod 6 and the piston plate 5 to move back and forth laterally.

[0053] During its reciprocating motion, the piston plate 5 draws the gas from the fixed cylinder 3 into the piston box 4 through the air inlet check valve, creating a negative pressure inside the fixed cylinder 3 and strengthening the fixation of the fixed cylinder 3 to the installation point. At this time, as the piston plate 5 continues to reciprocate, the gas from the fixed cylinder 3 is continuously drawn into the piston box 4, causing the negative pressure inside the fixed cylinder 3 to continue to increase, ensuring that the fixed cylinder 3 can be firmly installed in the soil at the installation point.

[0054] When the gas in the piston box 4 is discharged into the disturbance cylinder 12 through the blowing hole, it will disturb the gas in the disturbance cylinder 12. At this time, since the gas in the piston box 4 is sucked out from the fixed cylinder 3, and since the fixed cylinder 3 is located inside the soil, there is a certain temperature difference between the gas temperature therein and the external gas temperature. When the piston box 4 draws out the gas in the fixed cylinder 3 and discharges it into the disturbance cylinder 12, since the disturbance cylinder 12 is located on the outer wall of the fixed cylinder 3, the gas can exchange heat with the fixed cylinder 3 when entering the disturbance cylinder, thereby achieving a cooling effect on the fixed cylinder 3. At the same time, since the gas will also take away some heat during the flow process, the gas will further take away the heat from the fixed cylinder 3 when circulating in the disturbance cylinder 12, thereby enhancing the cooling effect on the fixed cylinder 3.

[0055] When rainwater passes through the collection frame 1 and enters the treatment tube 2, the filter plate 10 filters impurities in the rainwater, allowing the filtered rainwater to enter the collection chamber, reducing the possibility of impurities entering the collection chamber and affecting the precipitation amount. At the same time, when rainwater falls into the collection frame 1, thanks to the inverted conical design of the collection frame 1, it can expand the rainwater collection range, thereby increasing the chance of rainwater collection and improving the efficiency of precipitation monitoring. When the gas inside the piston box 4 is discharged through the disturbance hole, it also impacts the surface of the filter plate 10, thereby disturbing the impurities on the surface of the filter plate 10 and reducing the possibility of impurities clogging the filter plate 10. In this embodiment, the disturbance hole and the upper surface of the filter plate 10 are located on the same horizontal plane. When the gas impacts the surface of the filter plate 10, disturbing the impurities, the impurities will accumulate in the center of the filter plate 10, thereby reducing the accumulation of impurities at the junction of the filter plate 10 and the treatment tube 2. This further reduces the possibility of cleaning blind spots, allowing staff to quickly clean the impurities when cleaning them later, improving the cleaning efficiency of the device.

[0056] The staff sets the liquid level threshold through the controller. When the liquid level information of rainwater in the collection chamber reaches the liquid level threshold, the controller sends the liquid level information collected by the liquid level sensor to the staff terminal, and the staff goes to the location of the device to recycle the device.

[0057] The present invention reduces the interference of external impurities while lowering the storage temperature of rainwater through the coordinated work of the filtering component and the cooling component, thereby reducing temperature fluctuations, reducing the amount of heat evaporation of the collected rainwater, and ensuring the accuracy of precipitation data.

[0058] Example 2:

[0059] As attached Figure 3 As shown, the difference from Example 1 is that filter screens 14 are bonded to the disturbance holes.

[0060] The specific implementation process is as follows: when impurities are disturbed on the filter plate 10, the filter screen 14 can effectively prevent the impurities from entering the disturbance hole, reducing the possibility of impurities clogging the disturbance hole, and protecting the internal structure of the disturbance cylinder 12 and the treatment cylinder 2, thereby ensuring the stable operation of the device and improving the stability of the device.

[0061] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
