Description

Technical Field

[0001] The utility model relates to the technical field of water level monitoring, in particular to water level and water quantity monitoring equipment. Background Art

[0002] Water level and quantity monitoring equipment refers to a series of devices and systems used to monitor water levels, water volumes, and other parameters. They can monitor water level changes in rivers, lakes, reservoirs, farmlands, and other water bodies in real time. Water level and quantity monitoring equipment improves water resource management efficiency, disaster warning and flood prevention, enhances public safety, and increases agricultural yields. Farmland water level and quantity monitoring refers to the real-time monitoring and management of water levels and volumes in agricultural irrigation areas. This process is crucial for ensuring the rational use of water resources, improving irrigation efficiency, conserving water, and protecting the farmland ecosystem. Furthermore, the implementation of farmland water level and quantity monitoring can enhance irrigation districts' water resource management capabilities, rationally allocate water resources, predict and adjust irrigation plans, and promptly respond to droughts or water shortages. It also helps farmers manage fields based on crop water requirements, improve agricultural output, and protect environmental resources.

[0003] A search revealed a Chinese utility model patent publication numbered CN220960244U, which discloses a farmland water level monitoring device. The device comprises a frame, a floating plate disposed inside the frame, a monitoring ruler fixedly connected to the top of the floating plate, a pointer fixedly connected to the top of the frame, and a stabilizing assembly disposed on the outside of the frame. The device, which involves pulling a pull cap to move a slide and compressing a brass spring, disengages the latching rod from the slot, and inserts the fixed cone to the appropriate depth while contacting the connecting plate with the farmland ground. The pull cap is then released, and the compressed brass spring resets the slide and latching rod, locking the latching rod into the slot. Furthermore, the provision of inverted teeth stabilizes the fixed cone in the farmland, and a spirit level ensures that the device is level during deployment. As the water level in the farmland rises or falls, the floating plate rises or falls, driving the monitoring ruler up and down. By observing the pointer, the water level can be monitored in real time.

[0004] However, the above-mentioned device requires personnel to pay attention at all times when in use, but the above-mentioned equipment cannot remind surrounding personnel when the water level in the farmland is high, so as to avoid personnel failing to observe in time, resulting in water accumulation in the farmland, thereby affecting the respiration and nutrient absorption of the crop roots, and finally causing the root system of the crops to rot, or too little water in the farmland affects the development of the crop roots, resulting in poor development of the crops due to lack of water, and reduced crop yields. Not only that, when the filter of the above-mentioned equipment is clogged and needs to be cleaned or replaced, the filter needs to be disassembled. Since the filter is set at the bottom of the frame and connected by bolts, it is very inconvenient to disassemble the filter and it is not convenient to clean it regularly, which affects the detection effect of the water level and water volume. Utility Model Content

[0005] The purpose of the present invention is to provide a water level and water quantity monitoring device to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A water level and water quantity monitoring device comprises a detection shell, wherein sliding rods are fixedly installed on both sides of the inner bottom wall of the detection shell, the outer surface of the sliding rods is slidably connected to a floating plate, the top of the floating plate is fixedly installed with an upper pressure rod, brackets are fixedly installed at the four corners of the top of the detection shell, a placement plate is fixedly installed on the top of the bracket, a solar panel is fixedly installed on the top of the placement plate, a spirit level is fixedly installed on the side of the top of the placement plate close to the solar panel, a battery is fixedly installed at the center of the top of the detection shell, a first pressure sensor is fixedly installed on the inner bottom wall of the detection shell, and buzzers are fixedly installed on the tops of both sides of the detection shell.

[0008] By adopting the above technical solution, the solar panel is electrically connected to the battery, and the battery is electrically connected to the first pressure sensor and the buzzer respectively. When water enters the detection shell, the floating plate will move upward through the sliding rod, and the floating plate will move up with the upper pressure rod. When the water level inside the detection shell is too high, the upper pressure rod will press against the first pressure sensor, and the solar panel absorbs light energy and converts it into electrical energy and stores it in the battery. The battery provides power to the first pressure sensor and the buzzer. When the upper pressure rod presses against the first pressure sensor, the first pressure sensor transmits a signal to the buzzer, and the buzzer sounds an alarm to remind people around that the water level is too high. The placement plate is supported by the bracket, and the level is used to ensure the installation level when the equipment is installed.

[0009] Preferably, a mounting frame is provided in the middle of both sides of the detection shell, a filter is fixedly installed inside the mounting frame, fixing holes are provided on both sides of the top and bottom of the mounting frame, and movable grooves are provided on both sides of the detection shell near the top and bottom of the mounting frame, a brass spring is fixedly installed on the top wall of the movable groove, one end of the brass spring is fixedly connected to a fixing rod, and a paddle is fixedly installed on one side of the fixing rod.

[0010] By adopting the above technical solution, when the mounting frame is installed on both sides of the detection shell, the mounting frame squeezes the fixing rod, and the fixing rod moves and squeezes the brass spring, causing the brass spring to shrink under the force. When the fixing holes opened at the top and bottom of the mounting frame move to the fixing rod, the brass spring recovers its deformation, allowing the fixing rod to enter the fixing hole on the mounting frame to fix the mounting frame. The paddles are moved to both sides respectively, and the paddles move the fixing rod upward. The fixing rod disengages from the fixing hole during movement, and the mounting frame can be removed at this time.

[0011] Preferably, a slider is fixedly connected to one side of the fixed rod, a sliding groove is provided on the inner side wall of the movable groove, and a slider is slidably connected in the sliding groove.

[0012] By adopting the above technical solution, when the fixed rod moves, the slider will slide in the sliding groove along with the movement of the fixed rod, thereby ensuring the stability of the slider during movement.

[0013] Preferably, support plates are fixedly installed on the bottom of both sides of the detection shell, and a fixed cone is fixedly installed on the bottom of the support plate. The outer surface of the fixed cone is provided with a plurality of inverted teeth, and the bottom end of the fixed cone is conical.

[0014] By adopting the above technical solution, the support plate and the detection shell are inserted into the field through the fixed cone. Several inverted teeth can improve the stability of the detection shell and prevent the detection shell from tilting when exposed to wind. The conical setting of the bottom of the fixed cone makes it easier to insert the fixed cone into the field.

[0015] Preferably, a positioning plate is fixedly mounted on the front of the detection housing, a measuring ruler is fixedly mounted on the top of the positioning plate, a door is hinged on the back of the detection housing, and a handle is fixedly mounted on the front of the door.

[0016] By adopting the above technical solution, the measuring ruler is fixed by the positioning plate, and the user can judge the water level and water amount by observing the height of the water level on the measuring ruler.

[0017] Preferably, a mounting base is fixedly connected to the top of the measuring ruler, and a warning light is fixedly installed on the top of the mounting base.

[0018] By adopting the above technical solution, the warning light is electrically connected to the battery. The setting of the warning light provides an external warning, making it easier for personnel to find the equipment, and the bright light emitted by the warning light makes it easier for personnel to observe the position of the water level on the measuring scale.

[0019] Preferably, a lower pressure rod is fixedly mounted on the bottom of the floating board, and a second pressure sensor is fixedly mounted on the inner bottom wall of the detection housing.

[0020] By adopting the above technical solution, when the water level is low, the water level in the detection shell will also decrease. At this time, the floating plate slides down along the slide rod until the lower pressure rod presses the second pressure sensor. The second pressure sensor is electrically connected to the battery and the buzzer. The buzzer sounds an alarm to the outside to remind people around to pay attention to the water level.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This water level and quantity monitoring device, comprising a floating plate, an upper pressure rod, and a first pressure sensor, is configured such that when water enters the detection housing, the floating plate is affected by buoyancy and moves upward along the slide rod. Simultaneously, the two slide rods limit the floating plate to prevent it from tilting during upward movement. The floating plate moves upward, bringing the upper pressure rod with it. When the water level inside the detection housing is too high, the upper pressure rod presses against the first pressure sensor. The solar panel absorbs light energy and converts it into electrical energy, which is stored in a battery. The battery provides power to the first pressure sensor and a buzzer. When the upper pressure rod presses against the first pressure sensor, the first pressure sensor transmits a signal to the buzzer, which sounds an alarm, alerting nearby personnel that the water level is too high and to pay attention to the water level. Furthermore, when the water level is low, the water level inside the detection housing also drops. At this time, the floating plate slides down along the slide rod until the lower pressure rod presses against the second pressure sensor. The second pressure sensor is electrically connected to the battery and the buzzer, and the buzzer sounds an alarm, alerting nearby personnel to the water level, thereby preventing high or low water levels from affecting plant growth.

[0023] 2. This water level and water quantity monitoring device, through the arrangement of the brass spring, the fixing rod and the paddle, when the mounting frame is installed on both sides of the detection shell, the mounting frame squeezes the fixing rod, and the arrangement of the slider sliding in the slide groove makes the movement of the fixing rod more stable, the fixing rod moves and squeezes the brass spring, and the brass spring contracts under the force, and when the fixing holes opened at the top and bottom of the mounting frame move to the fixing rod, the brass spring recovers its deformation, allowing the fixing rod to enter the fixing hole on the mounting frame to fix the mounting frame, thereby facilitating the installation of the fixing frame and the filter screen. When the filter screen needs to be removed for cleaning, the paddles are respectively pushed to both sides, and the paddles move upward with the fixing rod, and the fixing rod disengages from the fixing hole when moving. At this time, the mounting frame can be removed, thereby facilitating the removal of the filter screen for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] It can be understood that when the moving rod moves, the slider 16 slides in the sliding groove 17, so that the moving rod moves more stably and does not tilt, which causes the moving rod to be unable to move.

[0047] Specifically, the measuring ruler 22 is fixed by the positioning plate 21, and the user judges the water level and the amount of water by observing the height of the water level on the measuring ruler 22. By setting the box door 28 and the handle 29, when in use, the detection housing 1 can be opened through the box door 28 by pulling the handle 29, thereby facilitating the inspection and maintenance of the interior of the detection housing 1.

[0048] It can be understood that a plurality of height slots are provided on the measuring ruler 22, and the user can closely observe the position of the water level line in the height slots provided on the measuring ruler 22 to judge the water level and water volume. Transparent glass is installed on the box door 28 to facilitate the user to observe the interior of the detection housing 1, so that when the internal parts of the detection housing 1 are damaged and cannot be used, the user can observe them in time and open the box door 28 through the handle 29, thereby achieving the effect of facilitating the maintenance of the internal parts of the detection housing 1;

[0053] like Figures 1 to 4 As shown in Comparative Example 1, another embodiment of the present invention is:

[0054] A lower pressure rod 23 is fixedly mounted on the bottom of the floating plate 3 , and a second pressure sensor 24 is fixedly mounted on the inner bottom wall of the detection housing 1 .

[0055] Specifically, when the water level in the field is low, the water level in the detection housing 1 will also drop. At this time, the floating plate 3 slides down along the slide bar 2 until the bottom end of the lower pressure rod 23 presses the second pressure sensor 24. The second pressure sensor 24 is electrically connected to the battery 7 and the buzzer 9. The battery 7 supplies power to the second pressure sensor 24 and the buzzer 9. The buzzer 9 sounds an alarm to the outside world, reminding people around to pay attention to the water level, thereby preventing the low water level from affecting the growth of crops and reducing crop yields.

[0056] It can be understood that the second pressure sensor 24 and the buzzer 9 are electrically connected to the battery 7 respectively. The reference model of the second pressure sensor 24 is MS563730BA03-50.

[0057] When a water level and quantity monitoring device of this embodiment is in use, the support plate 18 and the detection shell 1 are inserted into the field through the fixing cone 19. A number of inverted teeth 20 can improve the stability of the detection shell 1 to prevent the detection shell 1 from tilting when it is blown by the wind. Water flows into the detection shell 1 through the filter screen 11. When water enters the detection shell 1, the floating plate 3 moves up along the slide bar 2 under the influence of buoyancy. At the same time, the two slide bars 2 limit the floating plate 3 to prevent the floating plate 3 from tilting when it moves up. The floating plate 3 moves up with the upper pressure rod 4.

When the upper pressure rod 4 presses against the first pressure sensor 8, the first pressure sensor 8 transmits a signal to the buzzer 9, and the buzzer 9 sounds an alarm to remind the surrounding personnel that the water level is too high and to pay attention to the water level. Moreover, when the water level is low, the water level in the detection shell 1 will also drop. At this time, the floating board 3 slides down along the slide rod 2 until the lower pressure rod 23 presses the second pressure sensor 24. The second pressure sensor 24, the battery 7 and the buzzer The device 9 is electrically connected, and the buzzer 9 sounds an alarm to the outside to remind the surrounding personnel to pay attention to the water level, so as to avoid the situation where the water level is too high or too low and affects the growth of plants. When the mounting frame 10 is installed on both sides of the detection housing 1, the mounting frame 10 squeezes the fixing rod 14, and the setting of the slider 16 sliding in the slide groove 17 makes the fixing rod 14 move more smoothly. The fixing rod 14 moves and squeezes the brass spring 13, and the brass spring 13 is forced to shrink. When the fixing holes opened at the top and bottom of the mounting frame 10 move to the fixing rod 14, the brass spring 13 recovers its deformation, so that the fixing rod 14 enters the mounting The mounting frame 10 is fixed in the fixing hole on the frame 10, so as to facilitate the installation of the fixing frame and the filter 11. When the filter 11 needs to be removed for cleaning, the paddles 15 are respectively pushed to both sides, and the paddles 15 move upward with the fixing rods 14. The fixing rods 14 are disengaged from the fixing holes when moving. At this time, the mounting frame 10 can be removed, so as to facilitate the removal of the filter 11 for cleaning.
