Description

Technical Field

[0001] This utility model relates to the field of water immersion alarm technology, specifically a water accumulation early warning water immersion alarm. Background Technology

[0002] As is well known, a water immersion alarm is a device that sounds when a water container overflows, alerting the user to the presence of a leak or overflow so that people can take timely action. It is widely used in areas such as water accumulation alarms, home kitchens, and flood control. It is a device that automatically alarms when a low-lying area such as a foundation pit, tunnel, or road is submerged in water.

[0003] Existing water immersion alarms are often directly exposed and fixed in use, which has the following shortcomings: due to the inevitable presence of solid impurities in the environment and water bodies such as stagnant water, solid impurities can easily accumulate and cover the water immersion alarm, causing blockage and affecting its normal detection of water flow. There is also a lack of structures for intercepting and cleaning solid impurities. In view of this, this application proposes a water immersion alarm with early warning of water accumulation to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 5 As shown, the water accumulation early warning water immersion alarm proposed in this embodiment includes a water immersion alarm body 1 and a plug wire 101 connected to its left side. Iron clips 102 are fixedly connected to both sides of the top of the water immersion alarm body 1, and a self-cleaning solid sludge filter mechanism is provided on the outside of the water immersion alarm body 1.

[0027] The self-cleaning solid sludge filtration mechanism includes an annular support plate 2 sleeved on the outside of the main body 1 of the water immersion alarm. The annular support plate 2 is movably sleeved on the plug wire 101. A wire-passing hole 201 with an open bottom is opened on the left inner wall of the annular support plate 2. The plug wire 101 is located inside the wire-passing hole 201 and does not contact the inner side of the wire-passing hole 201. The wire-passing hole 201 and the open bottom facilitate the easy passage of the plug wire 101. A stainless steel filter screen cover 4 is rotatably installed on the top of the annular support plate 2. A first bearing is fixedly connected to the top of the annular support plate 2. The inner ring of the first bearing... The outer fixing set of the stainless steel filter screen cover 4 serves to rotate and install the stainless steel filter screen cover 4. The top four sides of the annular support plate 2 are fixedly connected to the support rods 3 located inside the stainless steel filter screen cover 4. The top of the four support rods 3 are fixedly connected to the same fixing box 301. The timer controller 6 is fixedly installed on the bottom inner wall of the fixing box 301. The bottom of the fixing box 301 is fixedly connected to two magnetic positioning components that are magnetically attached to the corresponding iron clips 102. The magnetic positioning components are used to cooperate with the two iron clips 102 to conveniently magnetically fix the fixing box 301 to the water immersion alarm body 1.

[0028] The fixed box 301 houses a rotary drive assembly electrically connected to the timer controller 6 and used to drive the stainless steel filter screen 4 to rotate. An L-shaped brush rod 8, which is in movable contact with the right side of the stainless steel filter screen 4, is fixedly connected to the right side of the annular support plate 2. The fixed box 301 also houses a backflushing and unblocking assembly electrically connected to the timer controller 6 and used to blow air onto the inner right side of the stainless steel filter screen 4. The stainless steel filter screen 4 is used to filter and intercept solids in the accumulated water, preventing large amounts of solids from entering and covering the water immersion alarm body 1, thus affecting its detection operation. The rotary drive assembly is controlled by the timer controller 6 to rotate the stainless steel filter screen 4 at regular intervals. The L-shaped brush rod 8 is used to clean the outer side of the stainless steel filter screen 4 as it rotates, reducing the accumulation of solids on the outer side and minimizing their impact on water flow. The backflushing and unblocking assembly blows air onto the rotating stainless steel filter screen 4 from the inside to the right, further ensuring long-term stability.

[0029] Specifically, the magnetic positioning component includes a sleeve 303 fixedly connected to the bottom of the fixing box 301. A magnet 302 is fixedly connected to the inner top wall of the sleeve 303. An iron block 102 is movably fitted into the corresponding sleeve 303 and attracted to the magnet 302. The sleeve 303 and the magnet 302 cooperate to achieve the locking and positioning of the fixing box 301 by the locking of the sleeve 303 and the iron block 102, and to achieve magnetic fixation by the magnetic attraction between the magnet 302 and the iron block 102.

[0030] Furthermore, the rotary drive assembly includes a motor 5 fixedly mounted on the inner wall of the bottom of the fixed box 301 and electrically connected to the timer controller 6. The output shaft of the motor 5 extends above the fixed box 301 and is fixedly connected to a turntable 501. The fixed box 301 is rotatably and sealed on the output shaft of the motor 5. The top of the fixed box 301 has a circular through hole, and a sealed bearing is fixedly fitted inside the circular through hole. The inner ring of the sealed bearing is fixedly fitted to the outer side of the output shaft of the motor 5, which achieves the effect of sealing and rotating the output shaft of the motor 5. The bottom of the turntable 501 is fixedly connected to the top of the stainless steel filter screen 4. The motor 5 and the turntable 501 cooperate. When the motor 5 is controlled by the timer controller 6 to turn on at a certain time, it will drive the turntable 501 to rotate, and the rotation of the turntable 501 will drive the stainless steel filter screen 4 to rotate.

[0031] Furthermore, the backflushing and unblocking assembly includes a water-air dual-purpose pump 7 fixedly installed on the inner wall of the bottom of the fixed box 301 and electrically connected to the timer controller 6. The inlet end of the water-air dual-purpose pump 7 extends to the bottom of the fixed box 301 and is connected to and fixedly connected to a suction pipe. An L-shaped pipe 701 is embedded and fixedly installed on the right side of the fixed box 301 and is connected to and fixedly connected to the outlet end of the water-air dual-purpose pump 7. The bottom end of the L-shaped pipe 701 is set as a sealing structure. Multiple cleaning pipes 702 are connected and fixedly connected to the right side of the L-shaped pipe 701. The cleaning pipes 702 are close to and cooperate with the inner right side of the stainless steel filter screen 4. The cleaning pipes 702 are located on the left side of the front side of the L-shaped brush rod 8 and are offset from the front side of the L-shaped brush rod 8. A lithium battery is fixedly installed on the inner wall of the bottom of the fixed box 301. The timer controller 6, the motor 5, and the water-air dual-purpose pump 702 are also included. Pump 7 is electrically connected to the lithium battery. The water-air dual-purpose pump 7, suction pipe, L-shaped pipe 701 and blowing pipe 702 are set up in cooperation. When the water-air dual-purpose pump 7 is turned on by the timer controller 6, it will draw gas or water from the inside of the stainless steel filter screen 4 and pump it into the L-shaped pipe 701. The gas or water is then blown out to the right through multiple blowing pipes 702. By approaching the right side of the inside of the stainless steel filter screen 4 and coordinating with its rotation, the stainless steel filter screen 4 is effectively cleaned and unblocked from the inside to the right. This reduces the phenomenon of water blockage and inability to detect caused by impurities in the filter holes of the stainless steel filter screen 4, and further ensures the stability of long-term use. The rightward blowing can also help to blow and clean the impurities that are concentrated on the front side of the L-shaped brush bar 8 when the rotating brush is cleaning.

[0032] The usage method of this embodiment is as follows: When in use, the main body 1 of the water immersion alarm is installed and fixed at the location where water is likely to accumulate and needs to be monitored. The wire part of the plug wire 101 is inserted into the wire hole 201. The annular support plate 2 is moved down so that the fixed box 301 is moved down through the support rod 3. The fixed box 301 drives the two clips 303 to clip onto the corresponding iron clips 102 respectively. The clips 303 drive the corresponding magnets 302 to attract with the iron clips 102, thereby achieving magnetic clamping and fixing of the fixed box 301. This achieves the fixing of the self-cleaning solid residue filtration mechanism. At this time, the stainless steel filter screen 4 surrounds and blocks the outside of the main body 1 of the water immersion alarm. The stainless steel filter screen 4 filters and intercepts solid impurities from the outside and the water, preventing solid impurities from directly accumulating and covering the main body 1 of the water immersion alarm and causing blockage.

[0033] Based on the required cleaning intervals according to the site environment, the start and stop times and intervals of the control motor 5 and the water-air dual-purpose pump 7 are preset using the timer controller 6. For example, if personnel are required to clean once a day, the control motor 5 and the water-air dual-purpose pump 7 can be set to start once every 24 hours, with each start-up and shutdown time set to one minute. When the cleaning time is reached, the timer controller 6 controls the motor 5 and the water-air dual-purpose pump 7 to start. When the motor 5 starts, it drives the turntable 501 to rotate, which in turn drives the stainless steel filter screen 4 to rotate. When the stainless steel filter screen 4 rotates, it rubs against the L-shaped brush rod 8, using the L-shaped brush rod 8 to achieve the effect of cleaning the entire outer side of the stainless steel filter screen 4 as it rotates, reducing the phenomenon of large amounts of solids accumulating on the outside and affecting water flow. When the water-air dual-purpose pump 7 starts, it will draw in the gas or water inside the stainless steel filter screen 4 and pump it out. Gas or water is then blown to the right through multiple cleaning pipes 702 into the L-shaped tube 701. By using the right side of the stainless steel filter screen 4, which is close to the inside, and in conjunction with its rotation, the stainless steel filter screen 4 is effectively back-blown or back-flushed to clean and unclog it from the inside to the right. This reduces the phenomenon of water blockage and inability to detect caused by impurities in the filter holes of the stainless steel filter screen 4, and further ensures the stability of long-term use. The right-blowing air can also help to blow and clean the impurities that are concentrated on the front side of the L-shaped brush rod 8 during the rotating brush cleaning. When the closing time is reached, the timer controller 6 controls the motor 5 and the water-air dual-purpose pump 7 to shut down, and waits for the next cleaning time to restart to carry out the cleaning and unclogging work. This achieves the effect of timed automatic cleaning and back-flushing or back-blowing to unclog the outside of the stainless steel filter screen 4, improving its unobstructed flow and thus improving the stability of long-term detection.

[0034] When the main body 1 of the water immersion alarm needs to be inspected and maintained, personnel can pull the annular support plate 2 upwards so that it moves the fixed box 301 upwards via the support rod 3. The fixed box 301 causes the two clips 303 and the two magnet blocks 302 to separate from the corresponding iron clips 102, so that the self-cleaning solid slag filter mechanism can be removed, exposing the main body 1 of the water immersion alarm for personnel to carry out inspection and maintenance work. This makes it easy to disassemble and assemble the self-cleaning solid slag filter mechanism and facilitate subsequent inspection and maintenance work.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
