Detailed Embodiments
[0026] Next, in combination with the drawings and specific embodiments, the present invention will be further described:
[0027] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0029] Such as Figure 1A heating rain and snow gauge as shown in FIG. -4 includes a metering housing 10, a guiding assembly, and a metering assembly. A water inlet 11 is provided at the top of the metering housing 10, and a rainwater chamber 12 is provided in the metering cavity, and the water inlet 11 communicates with the rainwater chamber 12. The above guiding assembly is installed in the rainwater chamber 12, and the guiding assembly includes a guiding member and a first heating element 40. Specifically, the guiding member is provided with a guiding port 32 and a guiding surface 31. The above guiding surface 31 is located below the water inlet 11 and guides the water flow to the guiding port 32, and the first heating element 40 is arranged on the guiding surface 31. In addition, the above metering assembly is installed in the rainwater chamber 12, and the metering assembly can receive the water flow introduced from the guiding port 32 and perform rain gauge detection to send a rain gauge signal.
[0030] Based on the above structure, when using the heating rain and snow gauge of the present utility model, during rainwater metering, rainwater can be introduced through the water inlet 11 at the top of the metering housing 10 and guided to the guiding port 32 by the guiding surface 31 of the guiding member. In this way, the guiding port 32 can guide the rainwater to the metering assembly for rainwater metering detection to achieve accurate metering. If the guiding member is not provided, the rainwater introduced through the water inlet 11 will directly enter the rainwater chamber 12 for metering by the metering assembly. In this case, the rainwater is dispersed, and the metering assembly requires a relatively large receiving surface to perform metering, resulting in inaccurate rain gauge measurement results. In this embodiment, the guiding member directly guides the rainwater to the guiding port 32, and the rainwater is directly guided from the guiding port 32 to the metering assembly for metering, improving metering accuracy.
[0031] It should also be noted that when the rain and snow gauge is used in a low-temperature environment or a harsh environment, there may be rain and snow weather or hail weather. In this case, the water entering the water inlet 11 is rain and snow or ice or hail, etc., which cannot be directly measured and detected by the metering assembly. As a result, the rainwater detection result detected by the metering assembly is inaccurate. Therefore, in this application, the first heating element 40 is arranged on the guiding surface 31 of the guiding member to heat the guiding surface 31 of the guiding member. The rain, snow, ice or hail, etc. entering the guiding member from the water inlet 11 will directly melt on the guiding member to form rainwater and then enter the guiding port 32, so that the snow or ice on the guiding member can be introduced in a flowing state of rainwater. In this way, the rainwater result detected by the metering assembly includes both the amount of rainwater itself and the amount of rainwater after melting of rain and snow, ice, etc., which can improve the accuracy of rainwater metering in a low-temperature environment.
[0032] Further, the guiding member in this embodiment is a guiding funnel 30. The peripheral edge of the top end of the guiding funnel 30 is connected to the inner peripheral wall of the rainwater chamber 12. Specifically, the outer peripheral edge of the top end of the guiding funnel 30 and the inner peripheral wall of the metering chamber can be connected by bonding, welding, clamping or other connection methods. And the above-mentioned guiding port 32 is provided at the bottom end of the guiding funnel 30, and the first heating member 40 is arranged on the outer side wall and / or the inner side wall of the guiding funnel 30. Since the guiding member is in the shape of a funnel, that is, the inner peripheral surface of the guiding funnel 30 can form an inclined guiding surface 31. The guiding funnel 30 has a larger receiving aperture above to receive the rainwater from the water receiving port 11, and then circulates along the guiding inclined surface of the guiding funnel 30, so that the rainwater can be evenly dispersed and guided to the guiding port 32, preventing the rainwater from flowing too fast into the metering assembly, which will also cause inaccurate metering.
[0033] And the above-mentioned first heating member 40 can be installed on the outer side wall of the guiding funnel 30, or can be installed on the inner side wall of the guiding funnel 30, or the first heating member 40 can be provided on both the inner side wall and the outer side wall of the guiding funnel 30. Specifically, in this embodiment, the first heating member 40 is arranged on the outer side wall of the guiding funnel 30, which can prevent the rainwater from directly contacting the first heating member 40 and improve the service life of the first heating member 40.
[0034] Further, the above-mentioned first heating member 40 includes a heating film. The heating film is attached to the outer side wall of the guiding funnel 30. In this embodiment, the above-mentioned heating film includes a heating wire and a heat-conducting silica gel. The heat-conducting silica gel is coated outside the heating wire, that is, the heating wire can be arranged inside the heat-conducting silica gel. The power connection terminals of the heating wire can extend from the ends of the heat-conducting silica gel respectively. The heating wire is powered to generate heat, and then the heat is conducted through the heat-conducting silica gel to heat the guiding surface 31. In this way, it is not the heating wire that directly heats, but the heat is guided through the heat-conducting layer formed by the heat-conducting silica gel, and the heating is more uniform.
[0035] Of course, it is also possible to directly arrange a heating wire structure inside the guiding member to form the above-mentioned first heating member 40. The structure of the first heating member 40 can be selected according to actual needs.
[0036] Further, an isolation sleeve 50 can also be provided in the rainwater chamber 12. The bottom end of the isolation sleeve 50 is connected to the bottom end of the rainwater chamber 12, and the top end of the isolation sleeve 50 surrounds the bottom end of the guiding funnel 30, and a sealing rubber sleeve 60 is provided between the outer peripheral edge of the top end of the isolation sleeve 50 and the outer peripheral edge of the bottom end of the guiding funnel 30; the metering assembly is arranged inside the isolation sleeve 50.
[0037] In this way, the rainwater led out from the guiding port 32 at the bottom end of the guiding member can be directly guided to the guiding and metering assembly inside the isolation sleeve 50 for rainwater metering, that is, the rainwater is introduced into the isolation sleeve 50 to prevent it from flowing outside the isolation sleeve 50 and affecting other parts inside the metering housing 10.
[0038] Further, in this embodiment, a controller, a temperature detector, and a circuit board 13 are provided in the rainwater cavity 12. Specifically, the controller is electrically connected to the circuit board 13. The temperature detector can detect the heating temperature of the first heating element 40 and send a temperature signal to the controller. Both the above-mentioned controller and the circuit board 13 are arranged outside the isolation sleeve 50, and the circuit board 13 is electrically connected to the first heating element 40 and the metering assembly.
[0039] Based on this structure, the working circuits of the first heating element 40 and the metering assembly are integrated onto the circuit board 13. During use, when the first heating element 40 heats, the temperature detector detects the heating temperature. The temperature signal detected by the temperature detector can be received by the controller. After the controller receives that the heating temperature reaches the preset value, it can control the first heating element 40 to stop working, preventing the first heating element 40 from overheating and causing rainwater evaporation, so that the heating temperature on the rainwater guiding member can just make snow or ice or the like melt into a flowing state of rainwater.
[0040] In this way, when the rain and snow gauge is in an environment with a low temperature and there are rain and snow conditions, freezing rain, hail or other weather conditions, it can keep the rainwater flowing in the heating state and imported for accurate measurement, improving the accuracy of the measurement result.
[0041] In addition, structures such as the controller and the circuit board 13 are all located outside the isolation sleeve 50, isolating the rainwater to prevent the rainwater from being imported and affecting the damage of the controller and the circuit board 13, and improving the service life of the controller, the circuit board 13, etc.
[0042] Further, a filter element can be provided in the guiding port 32. The filter element can filter impurities in the guiding port 32. Since the rain and snow gauge is used outdoors, it is inevitable that dust, bird droppings, fallen leaves or other impurities will fall onto the guiding member through the water receiving port 11. If such impurities directly enter through the guiding port 32 and are received by the metering assembly, there will be a measurement error. Therefore, in this application, the filter element in the guiding port 32 filters out the impurities, that is, the rainwater introduced through the guiding port 32 is filtered out of impurities, making the measurement result more accurate.
[0043] Further, the filter element is a filter spring 33. The top end of the filter spring 33 extends out of the guiding port 32, and the bottom end of the filter spring 33 is inserted into the guiding port 32. Since the spring is formed by dispersing a plurality of spring coils, the intervals between the spring coils of the filter spring 33 can filter out impurities without affecting the entry of rainwater, achieving a filtering effect.
[0044] Of course, the above-mentioned filter element can also be selected as other structures such as a filter net in the prior art that can pass water but not impurities, and can be specifically selected and set according to actual needs.
[0045] Furthermore, a second heating element 90 is also provided at the bottom end of the rainwater chamber 12. The second heating element 90 is used to heat the rainwater chamber 12. In this way, heating can be carried out inside the rainwater chamber 12 by the second heating element 90. When the rain and snow gauge is used in a low-temperature environment, although the first heating element 40 provided on the guiding member below the water inlet 11 can heat the imported ice and snow, hail, etc., and convert them into rainwater and then enter the rainwater chamber 12 for rainwater measurement. However, due to the low temperature in the rainwater chamber 12 in a low-temperature environment, the rainwater in the chamber is also likely to freeze. Therefore, the second heating element 90 is further provided. The second heating element 90 can heat the inside of the rainwater chamber 12, so that the environment in the rainwater chamber 12 remains unfrozen. In this way, the rainwater introduced through the guiding port 32 is not likely to freeze, and the metering assembly in the rainwater chamber 12 can perform normal metering.
[0046] It should be noted that the second heating element 90 can be selected to have the same structure as the first heating element 40, or other heating structures such as heating tubes or heating wires in the prior art can be selected to achieve this.
[0047] Furthermore, in this embodiment, the above-mentioned metering assembly includes a metering frame 80 and a tipping bucket 81. The metering frame 80 is installed on the bottom wall of the rainwater chamber 12. Specifically, a weighing sensor is provided at the bottom end of the metering frame 80. The tipping bucket 81 is rotatably installed on the metering frame 80 through a rotating shaft 82, and the tipping bucket 81 can receive the water flow discharged from the guiding port 32 and can be turned over under the action of gravity. In addition, a counter is provided on the rotating shaft 82. The counter can record the number of rotations of the rotating shaft 82 and transmit the rotation number signal; the weighing sensor is used to record the weight of the rainwater in the metering frame 80 and transmit the weight signal. That is, in this embodiment, the rotation number signal and the weight signal together form a rainfall signal.
[0048] Based on the above structure, when rainwater is measured, the rainwater can enter the interior of the metering housing 10 through the water inlet 11 on the metering housing 10 and be guided to the guiding port 32 by the guiding surface 31 of the guiding member. In this way, the rainwater introduced through the guiding port 32 can drip and be received by the tipping bucket 81. After the tipping bucket 81 receives the rainwater, the weighing sensor can detect the weight of the rainwater and perform detection according to the weight of the rainwater.
[0049] Meanwhile, during continuous rainfall, the amount of rain in the tipping bucket 81 gradually increases. When the amount of rain increases to a certain extent, the center of gravity of the tipping bucket 81 will deviate from the rotating shaft 82 under the action of the rainwater, and then the tipping bucket 81 will flip. After flipping, the rainwater in the tipping bucket 81 is emptied, and the weight signal on the weighing sensor is reset for reweighing. That is, in the case of heavy rainfall, the tipping bucket 81 can flip to automatically empty the rainwater, and each weighing will be reset and remeasured after resetting, realizing continuous weighing after automatic emptying, and there will be no situation where the weighing is inaccurate due to too much rainfall.
[0050] In addition, each time the tipping bucket 81 flips, the rotating shaft 82 of the tipping bucket 81 rotates once, and the counter on the rotating shaft 82 can count once. In this way, the rainfall can be measured by combining the weight signal transmitted by the weighing sensor and the number of rotations of the rotating shaft 82 with two sets of data to form a rainfall signal, so that the measurement accuracy of the rainfall signal is higher.
[0051] Of course, the above metering component can also be used to detect rainfall by simply combining the flipping of the tipping bucket 81 with the counter for flipping technology, or can be used to detect rainfall by simply weighing the rainwater with the weighing sensor.
[0052] Furthermore, in this embodiment, a drain port 14 can also be provided at the bottom end of the metering housing 10, and the drain port 14 is covered with a screen. Based on this structure, the rainwater discharged from the tipping bucket 81 can be led out through the drain port 14 of the metering chamber, which is convenient for drainage. The screen covering the drain port 14 can concentrate the water after the tipping bucket 81 is emptied at one time and then lead it out after being dispersed by the screen.
[0053] Furthermore, in order to facilitate the installation and use of the rain and snow gauge outdoors, a base 20 can be provided at the bottom end of the metering housing 10, and an insertion tube 21 is provided on the base 20. By setting up a support rod structure outdoors and inserting the support rod structure into the insertion tube 21 of the base 20 and then locking it with a bolt structure, the installation can be realized, and the disassembly and assembly are convenient.
