Definitions

  • An invention relates to weight rain gauges with automatic discharge of collected and measured precipitation.
  • a weight rain gauge weighs an amount of precipitation fallen into a collecting vessel that has to be manually emptied after a certain amount of time and that requires a personal visit at a sometime very remote and inaccessible place of installation. Not being clogged by any dirt is an advantage of the weight measurement principle.
  • a tipping bucket gauge is another type of a rain gauge. It collects precipitation into a small size seesaw bucket divided into two parts. After one part of the tipping scales is filled the lever pivots pouring out the collected water. One tip represents a precise amount of collected precipitation. It is a measurement of small amounts of precipitation that are directed through a retaining funnel. Low accuracy of measurement at higher intensity of precipitation, losses on the funnel and frequent clogging are the disadvantages. Said cause disability of further measurement and manual intervention in order to clean the device is necessary.
  • the device of the latter type is described in EP2 720 070 A1 , it contains a receiving funnel arranged every time above one of the chambers of the tipping mechanism that is arranged on the scales and has a programmable evaluation unit.
  • the device also uses for measurement of precipitation amount the precipitation weight in addition to the number of tips of the tipping scales, the high intensity precipitation measurement error was not eliminated.
  • the opening of the receiving funnel is too small and is therefore easily blocked by dirt and the chambers of the tipping mechanism are too small, tipping is too frequent, water sprays out into surrounding and therefore inaccuracies in precipitation amount measurement occur.
  • the objective of the invention was to create a device that would measure the precipitation amount with higher accuracy and yet did not require frequent presence of an operator.
  • the weight rain gauge with automatic discharge comprises an outer housing provided in its upper part with a collecting cone with an opening for receiving precipitation.
  • a weighting device connected to an electronic module and a holder carrying a movably pivotaily arranged collecting reservoir is arranged inside the outer housing.
  • the subject- matter of the present invention is that the holder arranged on the weighting mechanism for measurement of total weight and weight gain of the collected precipitation and the collecting reservoir for collecting precipitation are eccentrically attached onto the holder and comprising a curved or angular bottom with an angle a smaller than 180°. it is preferable that the angle a is between 100 and 175°, more preferably between 150 and 170°.
  • the side walls, a pouring edge and a rear wail opposite the pouring edge are arranged around the bottom.
  • the pouring edge is preferably formed in the most upper part of the angular bottom if the collecting reservoir is in the basic position.
  • the collecting reservoir is rotatabiy pivotaily mounted on the holder so that the collecting reservoir pivotaily turns around the rotation axis in the direction of the pouring edge that by means of gravity and weight of the collected precipitation decreases if the amount of collected precipitation in the collecting reservoir reaches a predetermined level.
  • the collecting reservoir is emptied over the pouring edge.
  • a counterweight for returning the empty collecting reservoir into the basic position after pouring out collected precipitation is arranged on the rear wail.
  • the rain gauge contains a stop for stabilisation of the basic position of the collecting reservoir. The stop is preferably formed under the bottom in the rear side of the collecting reservoir.
  • the collecting reservoir for collecting precipitation is positioned in two pins arranged opposite to each other that are arranged on two opposite side walls of the collecting reservoir.
  • the turning mechanism is preferably positioned in the lower half as to the height of the collecting reservoir.
  • the turning mechanism, part of which is in the collecting reservoir and another part on the holders, has to be positioned on the side walls of the collecting reservoir so that in the basic position the collecting reservoir abuts the stop by its lower side of the bottom surface and said position changes only when the collecting reservoir is filled with precipitation up to the predetermined level or up to the pouring edge.
  • the position of the turning mechanism on the side walls of the collecting reservoir also depends on the size of the angle a enclosed by two parts of the angular bottom.
  • the collecting reservoir can have a section of substantially quadrangular shape; according to another embodiment a section can have polygonal, oval or round shape.
  • the stop is formed on the holder of the collecting reservoir.
  • the collecting cone is provided with an opening of the size of 10 to 100 % of the cross sectional area of the collecting reservoir.
  • the opening of the collecting cone can be provided with a cylindrical protective mesh provided with a protective cover in order to prevent leaves and dirt from leaking into the inner part of the outer housing.
  • the collecting reservoir can have a volume of 100 to 5000 ml depending on the size of the cross section of the outer housing, preferably 1000 to 5000 ml.
  • the collecting reservoir for collecting precipitation with such a volume is sufficiently large for collecting and precise weighting of weight gain, total precipitation, even in areas with abundant precipitation.
  • a strain gauge weighting element is suitable to be used as a weighting mechanism.
  • the weight rain gauge with automatic discharge according to the present invention is designed so that advantages of weight measurement of precipitation into the collecting reservoir as well as of a tipping principle for its automatic discharge are used.
  • the weighting mechanism is connected to the electronic module.
  • the collecting reservoir of the design according to the present invention is positioned on the holder in pivot pins and the holder is placed on the measurement strain gauge weighting device. Precipitation is cumulated in the collecting reservoir through the sufficiently big opening of the collecting cone. After the collecting reservoir is filled up to a certain level equilibrium of the basic position is breached and the collecting reservoir is tipped by automatic effect of gravity and the collected and weighted precipitation water is discharged. The amount of collected water is measured by means of weighting in the reservoir and the number of tips is not counted as it is the case in the known tipping principle.
  • the collecting reservoir is significantly larger than the chamber of the device using the tipping principle. Accordingly, the opening of the collecting cone can be significantly bigger, which eliminates clogging of the opening caused by dirt or mechanical particles and tree leaves.
  • FIG. 1 illustrates the layout of devices inside the rain gauge.
  • Fig. 2 is a view of the interior of the rain gauge rotated by 90° compared to Fig. 1.
  • Fig. 3 shows a detail of the collecting reservoir for collecting precipitation seen from above.
  • Fig. 4 represents a top view of the rain gauge with a protective cover and a mesh.
  • the weight rain gauge with automatic discharge as depicted on Fig. 1 consists of a holder 1, the collecting reservoir is pivotally arranged on by means of pins 2.
  • Pins 2 are positioned on opposite side walls 3 in the lower half of the collecting reservoir 3 in terms of its height.
  • Said two parts of the bottom of the collecting reservoir 3 enclose the angle a, which in this case is around 160°.
  • the end of the inclined part of the bottom forms pouring edge 12.
  • Position of pivot pins on opposite side walls 13 of the collecting reservoir 3 depends on the position of the bottom line and on the size of the angle a.
  • collecting reservoir 3 consists of side walls 3 and rear wall 14 provided with counterweight 4 for returning the collecting reservoir 3 into the basic position after discharging precipitation.
  • Stop 5 under collecting reservoir 3 is formed in order to ensure correct equilibrium position, i.e. the basic position, of the collecting reservoir 3.
  • the whole equipment is positioned on base plate 7, which forms the bottom of outer housing 8.
  • Base plate 7 includes a cut-out for draining discharged rain water from collecting reservoir 3 outside the rain gauge interior.
  • Weighting mechanism 6, for weighting collected precipitation in collecting reservoir 3 connected to the electronic module for measuring and evaluation of weight gain of precipitation as well as total weight of precipitation is positioned on base plate 7.
  • a strain gauge weighting element was used as weighting mechanism 6.
  • Collecting cone 0 with an opening for collecting precipitation is positioned in the upper part of outer housing 8.
  • the opening of collecting cone 0 for collecting precipitation is sufficiently large in order to eliminate blockage with dirt or tree leaves.
  • the opening of the collecting cone has the size of 40 to 80 % of the surface of the opening of collecting reservoir 3.
  • the weight rain gauge according to the present invention contains a cylindrical protective mesh H arranged around the opening of collecting cone 10.
  • Protective cover 9 for preventing leaves and dirt from penetrating into the interior of outer housing 8 is attached above said mesh 1J_.
  • Weight rain gauge with automatic discharge operates in the following manner. Precipitation is collected into collecting reservoir 3 through collecting cone 10 having a big opening, advantage of which is preventing blockage with solid particles.
  • Collecting reservoir 3 with collected precipitation is mounted through an eccentrically positioned rotation mechanism by means of a holder onto a measuring sensor that continuously measures and evaluates the total weight and weight gain corresponding to the collected precipitation by means of electronics with implemented algorithm.
  • Collecting reservoir 3 is designed so that when collected precipitation reaches a certain amount there is a change to the state of equilibrium and tipping and discharging start at the same time. After being discharged it is returned to the basic position because of counterweight 4 positioned on the rear part of collecting reservoir 3. Accuracy of measurement is ensured by quick discharge of collecting reservoir 3 and long periods between discharging achieved by sufficiently large collecting reservoir 3.
  • the invention is utilizable at construction, manufacture and subsequent use of rain gauges.
