Description
The present utility model relates to the field of
agriculture, and more particularly to float liquid level gauges and may be used
in plant growing, in particular, flowers, berries, seedlings and ornamental
plants in greenhouses, rooms, and on open ground.
The major drawback of the similar devices lies in
design complexity caused by the presence of a flexible bar or a flexible link,
which connects the float to a counterweight and passes via one or two blocks.
The most similar to a float liquid level gauge in
accordance with the present technical solution is the float level gauge
disclosed in Russian Federation Patent Serial No. RU 2003117489, IPC G01F 1/00,
published on December 10, 2004, comprising a body, a float, and a level
indicator.
The drawbacks of the above prototype include design
complexity caused by the presence of a flexible link, blocks, and insufficient
effectiveness of indication of level indicator position.
The technical result to be achieved is a simpler
design and higher effectiveness of indication of level indicator position.
According to the first embodiment, the technical
solution comprises a body, a float, and a level indicator, and differs from its
prototype in that a pusher is connected to the float from above; the level
indicator which is configured in the form of a rod having a three-dimensional
or two-dimensional shaped element at the upper end thereof is connected to the
upper end of the pusher via a pivot or flexible connection.
According to the second embodiment, the technical
solution comprises a body, a float, and a level indicator and differs from its
prototype in that the level indicator is configured in the form of two rods;
first ends of the rods are connected to the upper end of a pusher via a pivot
or flexible connection; second ends of the rods contact to the horizontal
surface of the area which surrounds the upper end of the body; and shaped
elements are connected to the middle portion of each rod.
According to the third embodiment, the technical
solution comprises a body, a float, and a level indicator and differs from its
prototype in that the level indicator comprises two parts which are connected
to each other with a pivot pin; a lower portion of the level indicator rests on
the horizontal surface of the area which surrounds the upper end of the body;
the upper part of the level indicator is connected via a pivot connection to
the upper end of a pusher by means of a slot in the upper part of the level
indicator, wherein the length of this slot being determined by range of
displayed liquid levels.
The technical solution will now be described in
detail by way of example, with reference to the accompanying figures, in
which:
Fig. 1 is a cross-sectional side view of the first
embodiment wherein the float is in its upper position;
Fig. 2 is a cross-sectional side view of the first
embodiment wherein the float is in its lower position;
Fig. 3 is a cross-sectional side view of the second
embodiment wherein the float is in its upper position;
Fig. 4 is a cross-sectional side view of the second
embodiment wherein the float is in its lower position; and
Fig. 5 is a cross-sectional side view of the third
embodiment wherein the float is in its lower position.
The float liquid level gauge in accordance with the
first embodiment comprises a body 1, a float 2, and a level indicator 3. A
pusher 4 is connected to the float 2 from above. The level indicator 3 is
connected to the upper end of the pusher 4 via a pivot or flexible connection
5, wherein the level indicator is configured in the form of a rod with a
three-dimensional or two-dimensional element 6 at the upper end thereof (Figs.
1, 2). The body 1 may be fastened to a housing of a containing liquid reservoir
8 by means of a fastening element 7.
At the maximum permissible liquid level and when the
float 2 is in its upper position within the body 1, the pusher 4 having the
pivot or flexible connection 5 is above the upper edge of the body 1. In this
case the end of the level indicator 3 coupled to the pivot or flexible
connection 5 is also above the upper edge of the body 1, and its spatial
position is close to the horizontal position. The three-dimensional or
two-dimensional element 6 is also in the lower position, and its position
indicates effectively and demonstrably a high liquid level in a storage-type
watering device (Fig. 1).
At the lower liquid level and when the float 2 is in
its lower position within the body 1, the pusher 4 having the pivot or flexible
connection 5 is below the upper edge of the body 1. In this case the end of
level indicator 3 coupled to the pivot or flexible connection 5 is also below
the upper edge of the body 1, and its spatial position is close to the vertical
position. The three-dimensional or two-dimensional element 6 is in the upper
position and its position indicates effectively and demonstrably the low liquid
level within the reservoir 8 (Fig. 2).
The body 1 has internal dimensions sufficient to
ensure free movement of the float 2 when the liquid level changes, wherein the
liquid inflow into the body 1 from the volume of the reservoir 8 surrounding
the body 1 occurs due to the open lower end of the body 1. If the float 2 is
sphere-shaped, the body 1 may be configured in the form of a pipe (Figs. 1, 2,
3, 4 and 5).
The three-dimensional or two-dimensional element 6
may be configured in the form of either a thin shaped plate, or a spherical
shape, or an ornamental figure of an animal, a fairy-tale character, or a
plant, e.g. flower. Colors of the three-dimensional element 6 are selected as
desired by the user. In particular, the three-dimensional element 6 may be of
monochrome color, for example of bright red, orange, or yellow color the most
visible against the background of plants which grow nearby. The
three-dimensional element 6 is made of light-weight material such as plastic
material or metal foil. Said embodiments of the three-dimensional element 6
improve effectiveness of indication of the level indicator 3 position by
improving the visibility of the spatial position of the level indicator 3.
According to the second embodiment of the float
liquid level gauge the level indicator 3 may be configured in the form of two
rods. First ends of the rods of the level indicator 3 are connected to the
upper end of a pusher 4 via the pivot or flexible connection 5. Second ends of
the rods of the level indicator 3 contact with the horizontal surface of the
area which surrounds the upper end of the body 1; shaped elements 9, 10 are
connected to the middle portion of each rod (Figs. 3, 4). The shaped elements
9, 10 may be configured in a styled shape of wings of birds or insects, for
example, butterfly.
Colors of the shaped elements 9, 10 are selected as
desired by the user. In particular, the shaped elements 9, 10 may be of
monochrome color, for example, of bright red, orange, or yellow color the most
visible against the background of growing nearby plants, or may have a
combination of different colors similar to the coloring of bird or insect
wings. The shaped elements 9, 10 may be made of light-weight material, such as
plastic material or metal foil.
According to the third embodiment of the float
liquid level gauge the level indicator 3 may comprise two parts, which are
connected to each other with a pivot pin 11 (Fig. 5). The lower part 12 of the
level indicator 3 rests on the horizontal surface of the area, which surrounds
the upper end of the body 1. The upper portion 13 of the level indicator 3 is
connected via the pivot connection 5 to the upper end of the pusher 4 by means
of a slot 14 in the upper part 13 of the level indicator 3 (Fig. 5). The length
of the slot 14, thus, is determined by a range of displayed liquid levels.
The parts 12 and 13 of the level indicator 3 of the
float liquid level gauge in accordance with the third embodiment may be
configured in a styled shape of the head of an animal, such as dog, frog,
crocodile, etc. In this case the lower part 12 may have the form of the lower
jaw of the head and the upper part 13 may have the form of the upper jaw of the
animal head.
Colors of the parts 12, 13 are selected as desired
by the user. In particular, the parts 12, 13 may be of monochrome color, for
example, of bright red, orange, or yellow color the most visible against the
background of plants which grow nearby, or may have a combination of different
colors similar to animal head coloring. The parts 12, 13 may be made of light
material such as plastic material or metal foil.
The float liquid level gauge in accordance with the
first embodiment may be operated as follows.
When the liquid level changes from the lowest to the
highest level, the float 2 lifts up to its upper position within the body 1.
Spatial position of the level indicator 3 changes from that close to the
vertical to that close to the horizontal (Fig. 1). Deviation of the position of
the level indicator 3 from the vertical, when the float 2 moves to the upper
position or the lower position thereof staying at intermediate positions, is
made possible due to the connection of the pusher 4 to the level indicator 3
via the pivot or flexible connection 5.
When the liquid level changes from the highest to
the lowest level, the float 2 sinks to its lower position within the body 1.
Spatial position of the level indicator 3 changes from that close to the
horizontal to that close to the vertical (Fig. 2). Thus, the presence of the
rod of the level indicator 3 having the three-dimensional element 6 at the
upper end thereof enhances considerably the visibility of the level indicator 3
position in space and provides more effective liquid level determination.
Deviation angle of the level indicator 3 position from the vertical when the
float 2 is in its lower position depends on relation between the level
indicator 3 thickness and internal horizontal size of the upper end of the body
1.
The float liquid level gauge in accordance with the
second embodiment is operated similarly to the operation of the float liquid
level gauge in accordance with the first embodiment.
When the liquid level changes from the lowest to the
highest level, the float 2 lifts up to its upper position within the body 1.
The spatial position of the level indicator 3 changes from the lower position
to the upper position (Fig. 3). When the level indicator 3 is in the upper
position thereof, the shaped elements 9, 10 are in a position close to the
horizontal, thereby ensuring their position minimal visibility.
When the liquid level changes from the highest to
the lowest level, the float 2 sinks to its lower position within the body 1.
The spatial position of the level indicator 3 changes from the upper position
to the lower position (Fig. 4). When the level indicator 3 is in the lower
position, the shaped elements 9, 10 are in the extended position close to the
vertical. In this case the visibility of the position of the level indicator 3
with the shaped elements 9, 10 in the space is, thus, improved considerably
and, therefore, more effective determination of the lower liquid level is
provided.
The float liquid level gauge in accordance with the
third embodiment is operated similarly to the operation of the float liquid
level gauge in accordance with the first embodiment.
When the float 2 is in its lower position, the parts
12 and 13 are moved apart from each other as much as possible as a result of
the rotation of the part 13 relative to the part 12 about the pivot pin 11 by
the action of the pusher 4 onto the lower edge of the slot 14 via the pivot
connection 5 (Fig. 5).
In this case the parts 12 and 13 simulate the head
of an animal with its mouth open this, in the given case, being perceived as
the need to slake its thirst, i.e., the necessity to supply water to the
reservoir 8.
