Description

Technical Field

[0001] This invention relates to the field of fire water tank level monitoring and alarm technology, and in particular to a fire water tank level monitoring and alarm device and method. Background Technology

[0002] A fire water tank is a fire-fighting facility that provides water to fire brigades during firefighting and rescue operations. Based on their purpose, they are divided into two categories: circulating fire water tanks and non-circulating fire water tanks. They have advantages such as good water quality, cleanliness and no pollution, high strength, and light weight. During use, fire water tanks require constant water level monitoring to prevent insufficient water supply for firefighting when the water level is low.

[0003] Existing fire water tank level monitoring and alarm devices typically monitor water levels using level sensors. These sensors are located within the water in the fire water tank. Over time, impurities from the water can accumulate on their surface, along with scale. The presence of these impurities and scale can cause inaccuracies in the monitoring accuracy of the sensors, leading to incorrect results and reducing the overall value of the device. Summary of the Invention

[0004] This invention discloses a fire water tank level monitoring and alarm device, aiming to solve the technical problem that existing fire water tank level monitoring and alarm devices generally monitor the water level through a water level sensor located in the water body of the fire water tank. Over a long period of time, impurities contained in the water body can easily adhere to the surface of the water level sensor, and scale can also form on its surface. The presence of impurities and scale can easily cause deviations in the monitoring accuracy of the water level sensor, resulting in erroneous monitoring results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fire water tank level monitoring and alarm device includes a water tank body. The top of the water tank body has a placement hole, and a split top plate is inserted into the placement hole. Two lifting rods are fixedly connected to the bottom of the split top plate, and the same cleaning assembly is provided on the outer side of the two lifting rods. The top of the split top plate has an insertion hole, and a filling column is inserted into the insertion hole. A through hole is opened at the top of the filling column, and a pull rod is fixedly connected inside the through hole. A mounting ring is fixedly connected to the bottom of the pull rod, and a water level sensor is fixedly connected inside the mounting ring. A handle is fixedly connected to the top of the pull rod. The cleaning assembly includes a cleaning cylinder, which is fixedly connected to the outer side of the two lifting rods. An alarm is fixedly connected to the top of the water tank body. Side clamps are fixedly connected at equal distances to both ends of the top of the split top plate, and the side clamps contact the sides of the water tank body.

[0007] Equipped with a cleaning component, after a period of use, pulling the lever moves the water level sensor upwards, activating the water pump. The pump draws water from inside the tank into the end pressure plates. Once inside the cleaning drum, the water level sensor comes into close contact with the brush strips. As it moves upwards, the brush strips, in conjunction with the brush cloth, achieve comprehensive cleaning of the water level sensor. The water pumped out from the nozzles cleans the sensor, removing scale and impurities from its exterior. When the water level sensor reaches near the top of the cleaning drum, the brushes on the end pressure plates perform a secondary cleaning, cleaning the irregular grooves and corners of the sensor. This ensures effective cleaning of the water level sensor in a single pass, guaranteeing that it remains in a high-precision working state.

[0008] In a preferred embodiment, an outer ring is fixedly connected to the outer side of the cleaning cylinder near the top, and a compression spring rod is distributed in a ring on the inner side of the outer ring facing the center point of the cleaning cylinder. Each compression spring rod is fixedly connected to an end compression arc plate. An inner groove is opened below the center line of the end compression arc plate. Spray holes are opened on the outer side of the end compression arc plate facing downward. Brush bristles are provided at equal intervals on the outer side of the end compression arc plate. Two sleeve rods are fixedly connected to the outer side of the outer ring, and the same connecting pipe is fixedly connected to the outer side of the two sleeve rods. The connecting pipe has a connecting hole at each end compression arc plate. A branch pipe is fixedly connected inside each connecting hole. The branch pipe is inserted into the interior of the adjacent end compression arc plate. A protective round rod is fixedly connected to the bottom of each end compression arc plate.

[0009] In a preferred embodiment, the cleaning cylinder has closely spaced brush strips arranged in a ring inside, and each closely spaced brush strip has a compression spring rod fixedly connected at equal intervals to its outer side. The compression spring rod is fixedly connected to the inner wall of the cleaning cylinder. The top and bottom of each closely spaced brush strip are fixedly connected to a guide plate. A flow channel is opened on the outer side of each closely spaced brush strip facing the center point of the cleaning cylinder. A brush cloth is provided on the outer side of the closely spaced brush strip outside the flow channel. A pump frame is fixedly connected to the outer side of one of the hanging rods. A water pump is fixedly connected to the top of the pump frame. A water inlet pipe is fixedly connected to the water inlet end of the water pump, and a water guide pipe is fixedly connected to the water delivery end of the water pump. The water guide pipe is inserted into the inside of the connecting pipe.

[0010] In a preferred embodiment, the split top plate is fixedly connected to a mating circular plate on the top of the outer side of the filling column, and the top of the mating circular plate has an circumferentially opened embedding groove, and the bottom of the handle has an circumferentially distributed embedding rods, which are inserted into the corresponding embedding grooves.

[0011] In a preferred embodiment, the top of the mating circular plate has a sliding groove, and four adjusting sliders are slidably connected inside the sliding groove. The same connecting bent rod is fixedly connected to the outer side of each pair of adjacent adjusting sliders. The top of each adjusting slider is fixedly connected to a misalignment rod, and the top of each misalignment rod is fixedly connected to a pressure block. Each inserting rod has a mating pressure groove on its upward-facing outer side.

[0012] In a preferred embodiment, the splitting top plate is provided with a wire winding assembly near the top of the docking circular plate, and the wire winding assembly includes two motor plates, both of which are fixedly connected to the top of the splitting top plate. One side of one motor plate is fixedly connected to a forward and reverse motor, and the output shaft of the forward and reverse motor is fixedly connected to a rotating shaft through a coupling. One end of the rotating shaft is connected to the outside of the other motor plate through a bearing, and a winding roller is fixedly connected to the outside of the rotating shaft.

[0013] By incorporating a wire winding assembly, the wire body connected to the water level sensor is wound around the outside of the winding roller. The winding roller and the follower guide wheel are used to arrange the wire body, preventing damage caused by a messy arrangement. Simultaneously, during the cleaning process of the water level sensor, the wire body rises accordingly. After the wire body rises, the initial state of the return spring rod is compressed. After the wire body is loosened and arranged, the return spring rod drives the follower guide wheel to rotate, thereby tightening the wire body. This ensures that during the cleaning process of the water level sensor, the wire body will not become entangled due to the water in its loose state.

[0014] In a preferred embodiment, connecting plates are fixedly connected to the outer sides of both motor plates, and the two connecting plates are connected to the same connecting shaft via bearings on opposite sides. A follower guide wheel is fixedly connected to the outer side of the connecting shaft. The same wire body is wound around the outer side of the follower guide wheel and the winding roller. One end of the wire body is located at the top of the water level sensor, and the other end of the wire body is connected to a power supply element. Side brackets are fixedly connected to the two sides of the follower guide rail near the top. Hydraulic cylinder three is fixedly connected to the opposite side of the two side brackets. Limit rods are fixedly connected to the output ends of the two hydraulic cylinder threes. The limit rods are in contact with the outer side of the wire body. Fixed rods are fixedly connected to the opposite side of the two connecting plates. Annular guide rails are fixedly connected to the opposite side of the two fixed rods. Sliding blocks are slidably connected inside the two annular guide rails. Follower rods are fixedly connected to the outer side of the two sliding blocks. Follower rods are fixedly connected to the outer side of the follower guide wheel. Fixed blocks are fixedly connected inside the two annular guide rails. A reset spring rod is provided between the fixed block and the sliding block located on the same annular guide rail.

[0015] In a preferred embodiment, the water tank body is provided with an impurity collection assembly near the bottom. The impurity collection assembly includes two mounting plates and a collection frame. Both mounting plates are fixedly connected to the inner sidewall of the water tank body near the bottom. Telescopic plates are fixedly connected to the top of both mounting plates. Two push blocks are fixedly connected to the top of the telescopic plates away from the mounting plates. Two hydraulic cylinders are fixedly connected to the inner walls of both sides of the water tank body above the mounting plates. The output end of the hydraulic cylinder is fixedly connected to the outer side of the adjacent push block. A water passage hole is opened on the top of both telescopic plates. A door opening is opened on the outer side of the water tank body below one of the mounting plates. A waste discharge door is connected to the inner wall of the door opening by a hinge.

[0016] In a preferred embodiment, two hydraulic cylinders are fixedly connected to one side of the water tank body, and the output ends of the two hydraulic cylinders are fixedly connected to the outside of the collection frame. A hollow extraction plate is fixedly connected to the open end of the collection frame. Extraction holes are equidistantly opened on the outside of the hollow extraction plate. An adsorption pump is fixedly connected to the side of the hollow extraction plate facing the inside of the collection frame. The adsorption end of the adsorption pump is connected to the inside of the hollow extraction plate through a pipe. A stop rod is fixedly connected to the outside of the hollow extraction plate at both the upper and lower ends of the adsorption pump. An electric telescopic rod is fixedly connected to the side of the stop rod facing the outside of the collection frame. The output ends of multiple electric telescopic rods located on the same stop rod are fixedly connected to the same sealing plate. A water passage hole is opened on the outside of the collection frame.

[0017] By incorporating an impurity collection component, if a small amount of impurities are present in the water inside the tank, these impurities will slowly accumulate at the bottom of the tank after prolonged stagnation. Hydraulic cylinder one then moves the telescopic plates together, separating the impurities at the bottom. Hydraulic cylinder two then moves the collection frame, activating the adsorption pump. The adsorption pump collects the mixture of impurities and water through extraction holes on the hollow extraction plate, guiding it entirely into the collection frame. Water is discharged through water passage two, while impurities remain in the collection frame, thus completing the impurity collection process and reducing the probability of contamination on the surface of the water level sensor.

[0018] A method of using a fire water tank level monitoring and alarm device, comprising the following steps:

[0019] Step 1: During daily monitoring, the water level inside the water tank is transmitted to the back-end control terminal via a water level sensor. If the water level is insufficient, the back-end control terminal will activate an alarm to remind staff to add water.

[0020] Step 2: After using the water level sensor for a period of time, pull the lever to move the water level sensor upwards and start the water pump. The water pump draws water from inside the water tank into the squeezing arc plates at each end. After the water level sensor moves into the cleaning cylinder, it comes into close contact with each of the close-fitting brush strips. As it continues to move upwards, the close-fitting brush strips work with the brush cloth to achieve all-round contact and cleaning of the water level sensor. The water pumped by the water pump is sprayed out from the nozzle, and the sprayed water has a cleaning effect on the water level sensor, removing the scale and impurities attached to its outside.

[0021] Step 3: When the water level sensor moves to the top of the cleaning cylinder, the bristles on the end-pressing arc plate perform a secondary cleaning action. The bristles clean the irregular grooves and structural corners on the water level sensor. After cleaning, the water level sensor is in a high-precision monitoring state.

[0022] As can be seen from the above, the fire water tank level monitoring and alarm device provided by the present invention has the following technical effects: after the water level sensor has been used for a period of time, pulling the lever moves the water level sensor upward, the water pump is started, and the water pump draws water from inside the water tank body into the extrusion arc plates at each end. After the water level sensor moves into the cleaning cylinder, the water level sensor comes into close contact with each close-fitting brush strip. During its continuous upward movement, the close-fitting brush strips, together with the brush cloth, achieve all-round close-fitting cleaning of the water level sensor. The water drawn by the water pump is sprayed out from the nozzle, and the sprayed water has a cleaning effect on the water level sensor, removing the scale and impurities attached to its outside. When the water level sensor moves to the top of the cleaning cylinder, the bristles on the end extrusion arc plate perform a secondary cleaning function, and the bristles clean the irregular grooves and structural corners on the water level sensor, thereby ensuring the single cleaning effect of the water level sensor and ensuring that the water level sensor is always in a high-precision working state.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] The fire water tank level monitoring and alarm device disclosed in this invention is mainly applied to existing fire water tank level monitoring and alarm devices. In general, water level monitoring is carried out by a water level sensor located in the water body of the fire water tank. Over a long period of time, impurities contained in the water body can easily adhere to the surface of the water level sensor, and scale can also be generated on its surface. The presence of impurities and scale can easily cause deviations in the monitoring accuracy of the water level sensor, resulting in incorrect monitoring results.

The top of the filling column 15 has a through hole, and a pull rod 12 is fixedly connected to the through hole. The bottom of the pull rod 12 is fixedly connected to an installation ring 14, and a water level sensor 11 is fixedly connected to the inside of the installation ring 14. A handle 17 is fixedly connected to the top of the pull rod 12. The cleaning component 6 includes a cleaning cylinder 601, and the cleaning cylinder 601 is fixedly connected to the outer side of the two hanging rods 10. An alarm 2 is fixedly connected to the top of the water tank body 1. Side clamps 4 are fixedly connected at equal distances to both ends of the top of the split top plate, and the side clamps 4 are in contact with the two sides of the water tank body 1.

[0037] Reference Figures 1-5 In a preferred embodiment, an outer ring 609 is fixedly connected to the outer side of the cleaning cylinder 601 near the top. A series of compression spring rods 611 are arranged annularly on the inner side of the outer ring 609 facing the center point of the cleaning cylinder 601. Each compression spring rod 611 has an end compression arc plate 607 fixedly connected to its end. An inner groove is formed below the center line of the end compression arc plate 607. Spray holes 616 are formed on the outer side of the end compression arc plate 607 facing downwards. Brush bristles 606 are evenly spaced on the outer side of the end compression arc plate 607. Two sleeve rods 610 are fixedly connected to the outer side of the outer ring 609. A common connecting pipe 608 is fixedly connected to the outer side of the two sleeve rods 610. Each connecting pipe 608 has a connecting hole at each end compression arc plate 607. A branch pipe 617 is fixedly connected inside each connecting hole and inserted into the interior of an adjacent end compression arc plate 607. The bottom of each of the compression arc plates 607 is fixedly connected to a protective round rod 615. Inside the cleaning cylinder 601, there are close-fitting brush strips 613 arranged in a ring. Each close-fitting brush strip 613 is fixedly connected to a compression spring rod 619 at equal intervals on its outer side. The compression spring rod 619 is fixedly connected to the inner wall of the cleaning cylinder 601. The top and bottom of each close-fitting brush strip 613 are fixedly connected to a guide plate 612. A drainage groove 618 is opened on the outer side of each close-fitting brush strip 613 facing the center point of the cleaning cylinder 601. A brush cloth 614 is provided on the outer side of each close-fitting brush strip 613 located in the drainage groove 618.

The water guide pipe 605 is inserted into the inside of the connecting pipe 608.

[0038] In a specific application scenario, after the water level sensor 11 has been used for a period of time, pulling the lever 12 moves the water level sensor 11 upwards, activating the water pump 603. The water pump 603 draws water from inside the water tank 1 into the end compression arc plates 607. After the water level sensor 11 moves into the cleaning cylinder 601, it comes into close contact with each of the close-fitting brush strips 613. As it continues to move upwards, the close-fitting brush strips 613, together with the brush cloth 614, achieve all-round close-fitting brushing of the water level sensor 11. The water pump 603 draws water and sprays it out of the nozzle 616. The sprayed water has a cleaning effect on the water level sensor 11, removing the scale and impurities attached to its outside. When the water level sensor 11 moves to the top of the cleaning cylinder 601, the bristles 606 on the end pressure arc plate 607 perform a secondary cleaning. The bristles 606 clean the irregular grooves and structural corners on the water level sensor 11, thereby ensuring the cleaning effect of the water level sensor 11 in one cleaning and ensuring that the water level sensor 11 is always in a high-precision working state.

[0039] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 In a preferred embodiment, the split top plate 3 is fixedly connected to the top of the filling column 15 outside the top of the split top plate 3, and the top of the split top plate 8 is annularly opened with an embedding groove 19. The bottom of the handle 17 is annularly distributed with embedding rods 16, which are inserted into the corresponding embedding grooves 19. The top of the split top plate 8 is opened with a sliding groove 18, and four adjusting sliders 22 are slidably connected inside the sliding groove 18. The same connecting bent rod 21 is fixedly connected to the outside of each pair of adjacent adjusting sliders 22. The top of each adjusting slider 22 is fixedly connected with a misaligned rod 23, and the top of each misaligned rod 23 is fixedly connected with a pressure block 20. The outer side of each embedding rod 16 facing upwards is opened with a mating pressure groove 24.

[0040] It should be noted that the design of splitting the top plate 3 facilitates the disassembly and assembly of the water level sensor 11 and its internal cleaning component 6. At the same time, during the cleaning process of the water level sensor 11, the water level sensor 11 can be cleaned simply by holding the handle 17 and pulling the lever 12 up and down, which is convenient and efficient.

[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8In a preferred embodiment, a wire winding assembly 9 is provided on the top of the splitting top plate 3 near the docking circular plate 8, and the wire winding assembly 9 includes two motor plates 908. Both motor plates 908 are fixedly connected to the top of the splitting top plate. A forward and reverse motor 907 is fixedly connected to one side of one of the motor plates 908. The output shaft of the forward and reverse motor 907 is fixedly connected to a rotating shaft 909 through a coupling. One end of the rotating shaft 909 is connected to the outside of the other motor plate 908 through a bearing. A winding roller 902 is fixedly connected to the outside of the rotating shaft 909.

[0042] In this invention, connecting plates 906 are fixedly connected to the outer sides of both motor plates 908, and the same connecting shaft 905 is connected to the opposite side of the two connecting plates 906 via bearings. A follower guide wheel 901 is fixedly connected to the outer side of the connecting shaft 905. The same wire body 13 is wound around the outer side of the follower guide wheel 901 and the winding roller 902. One end of the wire body 13 is located at the top of the water level sensor 11, and the other end of the wire body 13 is connected to a power supply element. Side brackets 916 are fixedly connected to both sides of the follower guide rail near the top. Hydraulic cylinders 915 are fixedly connected to the opposite side of the two side brackets 916.

The follower rod 912 is fixedly connected to the outer side of the follower guide wheel 901. A fixed block 910 is fixedly connected inside the two annular guide rails 904. A common reset spring rod 913 is provided between the fixed block 910 and the sliding block 911 located on the same annular guide rail 904.

[0043] It should be noted that the wire body 13 connected to the water level sensor 11 is wound around the outside of the winding roller 902. The winding roller 902 and the follower guide wheel 901 are used to arrange the wire body 13, avoiding damage caused by messy arrangement. At the same time, during the cleaning process of the water level sensor 11, the wire body 13 rises. After the wire body 13 rises, the initial state of the reset spring rod 913 is a compressed state. After the wire body 13 is relaxed and arranged, the reset spring rod 913 drives the follower guide wheel 901 to rotate, thereby tightening the wire body 13. This ensures that during the cleaning process of the water level sensor 11, the wire body 13 will not become entangled due to the water in a relaxed state.

[0044] Reference Figure 1 , Figure 2 , Figure 9 and Figure 10In a preferred embodiment, the water tank body 1 has an impurity collection assembly 5 located inside near the bottom. The impurity collection assembly 5 includes two mounting plates 502 and a collection frame 503. Both mounting plates 502 are fixedly connected to the inner sidewalls of the water tank body 1 near the bottom. Telescopic plates 501 are fixedly connected to the tops of both mounting plates 502. Two pushing blocks 505 are fixedly connected to the tops of the telescopic plates 501 away from the mounting plates 502. Two hydraulic cylinders 506 are fixedly connected to the inner walls of both sides of the water tank body 1 above the mounting plates 502. The output ends of the hydraulic cylinders 506 are fixedly connected to the outer sides of the adjacent pushing blocks 505. Water passage holes 504 are opened at the tops of both telescopic plates 501. A door opening is opened on the outer side of the water tank body 1 below one of the mounting plates 502. A waste discharge door 7 is connected to the inner wall of the door opening via a hinge. Two hydraulic cylinders 510 are fixedly connected to one side of the main body 1, and the output ends of the two hydraulic cylinders 510 are fixedly connected to the outside of the collection frame 503. A hollow extraction plate 507 is fixedly connected to the open end of the collection frame 503. An extraction hole 508 is opened at equal intervals on the outside of the hollow extraction plate 507. An adsorption pump 514 is fixedly connected to the side of the hollow extraction plate 507 facing the inside of the collection frame 503. The adsorption end of the adsorption pump 514 is connected to the inside of the hollow extraction plate 507 through a pipe. A stop rod 512 is fixedly connected to the outside of the upper and lower ends of the hollow extraction plate 507. An electric telescopic rod 513 is fixedly connected to the side of the stop rod 512 facing the outside of the collection frame 503. The output ends of multiple electric telescopic rods 513 on the same stop rod 512 are fixedly connected to the same sealing plate 511. A water passage hole 509 is opened on the outside of the collection frame 503.

[0045] Specifically, there are a small amount of impurities in the water inside the water tank body 1. When the water is left to stand for a long time, the impurities slowly accumulate at the bottom of the water tank body 1. Then, the hydraulic cylinder 1 506 is adjusted to drive the telescopic plate 501 to move. After the two telescopic plates 501 are connected, the impurities at the bottom are separated. Then, the hydraulic cylinder 2 510 is adjusted to drive the collection frame 503 to move, and the adsorption pump 514 is started. The adsorption pump 514 collects the mixture of impurities and water through the extraction hole 508 on the hollow extraction plate 507 and introduces it all into the collection frame 503. The water is discharged from the water passage hole 2 509, and the impurities are retained in the collection frame 503, thus completing the collection of impurities and reducing the probability of contamination on the surface of the water level sensor 11.

[0046] A method of using a fire water tank level monitoring and alarm device, comprising the following steps:

[0047] Step 1: During daily monitoring, the water level inside the water tank 1 is transmitted to the back-end control terminal via the water level sensor 11. If the water level is insufficient, the back-end control terminal will control the alarm 2 to sound an alarm, reminding the staff to add water.

[0048] Step 2: After the water level sensor 11 has been used for a period of time, pull the lever 12 to move the water level sensor 11 upwards and start the water pump 603. The water pump 603 draws water from the inside of the water tank body 1 into the extrusion arc plates 607 at each end. After the water level sensor 11 moves into the cleaning cylinder 601, the water level sensor 11 comes into close contact with each close-fitting brush strip 613. During its continuous upward movement, the close-fitting brush strip 613, together with the brush cloth 614, achieves all-round close-fitting brushing of the water level sensor 11. The water drawn by the water pump 603 is sprayed out from the spray hole 616. The sprayed water has a cleaning effect on the water level sensor 11, removing the scale and impurities attached to its outside.

[0049] Step 3: When the water level sensor 11 moves to the top of the cleaning cylinder 601, the bristles 606 on the end squeezing arc plate 607 play a secondary brushing role. The bristles 606 brush the irregular grooves and structural corners on the water level sensor 11. After the brushing is completed, the water level sensor 11 is in a high-precision monitoring state.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
