[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire water tank level monitoring and alarm device, comprising a tank body and an auxiliary maintenance structure connected to one side of the tank body. The auxiliary maintenance structure includes U-shaped ladder rods. A circular channel pipe is installed at the top of the tank body near one side. Two U-shaped ladder rods are arranged side by side in parallel. One end of the U-shaped ladder rod is inserted into the tank body from the inside of the circular channel pipe, and the other end is located outside the tank body and is fixedly connected to the outer side of the tank body through a diamond-shaped frame. The two U-shaped ladder rods are fixedly connected by several evenly arranged climbing rods. A monitoring structure is installed on the tank body, and a water inlet structure is connected to the top of the other side, and a water outlet structure is connected to the front bottom face.

[0006] Preferably, the circular channel tube is fitted with a cover plate located at the notch in the U-shaped escalator rod.

[0007] Preferably, the water inlet structure includes an external threaded pipe, a telescopic flexible hose is connected to the top of the tank through a connecting pipe, an internal threaded pipe is fixedly connected to the top of the telescopic flexible hose, an external threaded pipe is threaded to the bottom of the internal threaded pipe, an L-shaped water inlet pipe is threaded to the top of the external threaded pipe, and several stacked filter screens are installed inside the external threaded pipe.

[0008] Preferably, the cross-section of the telescopic hose is shaped like a corrugated accordion, and the L-shaped water inlet pipe has internal threads that match the internal thread of the pipe.

[0009] Preferably, the outer wall of the filter screen is fixedly connected to two symmetrically arranged perforated protrusions, and the inner wall of the external threaded tube is provided with two symmetrically arranged elongated grooves.

[0010] Preferably, the monitoring structure includes a main controller, which is installed on the front end of the housing. A U-shaped mounting plate is fixedly connected to the rear end of the housing near the bottom. An immersion pressure sensor and a temperature sensor are installed on the U-shaped mounting plate.

[0011] Preferably, the water outlet structure includes a water outlet pipe, two symmetrically arranged sloping side plates are fixedly connected to the bottom of the tank, and a sloping center plate is fixedly connected between the two sloping side plates.

[0012] Preferably, the U-shaped mounting plate has two parallel elongated cavities.

[0013] Preferably, the height of the center plate of the slope is lower than the height of the side plates of the slope.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] This application provides reliable hand grips through two U-shaped ladder bars in the auxiliary maintenance structure, ensuring the stability of maintenance personnel during climbing and operation, facilitating various subsequent maintenance operations.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 7 The diagram shows a fire water tank level monitoring and alarm device, which includes a tank body 1 and an auxiliary maintenance structure 2 connected to one side of the tank body 1. The auxiliary maintenance structure 2 includes U-shaped ladder rods 21. A circular channel pipe 25 is installed on the top of the tank body 1 near one side. Two U-shaped ladder rods 21 are arranged side by side in parallel. One end of the U-shaped ladder rod 21 is inserted into the tank body 1 from the inside of the circular channel pipe 25, and the other end is set outside the tank body 1 and is fixedly connected to the outer side of the tank body 1 by a diamond-shaped frame 26. The two U-shaped ladder rods 21 are fixedly connected by several evenly arranged climbing rods 23.

[0027] It is worth noting that the climbing path is precisely aligned with the position of the circular channel tube 25, guiding maintenance personnel directly to the entrance of the tank 1. During the climb, the evenly distributed climbing poles 23 provide stable support points for the feet, while the U-shaped handrails 21 on both sides provide reliable grips for the hands, ensuring the stability of the maintenance personnel during the climb and operation, facilitating various subsequent maintenance operations. The U-shaped handrails 21 reserved for climbing into the water tank 1 eliminate the need for subsequent carrying of the handrails for climbing in and out, making subsequent maintenance work more labor-saving and improving the convenience of maintenance work.

[0028] Please see Figure 1 and Figure 2 The circular channel pipe 25 is equipped with a cover plate 22. A notch 24 is provided on the cover plate 22 at the U-shaped ladder rod 21. This notch 24 facilitates the opening and closing of the cover plate 22. When maintenance is not required, the cover plate 22 can tightly close onto the circular channel pipe 25, effectively preventing external debris and rainwater from entering the tank 1. The cover plate 22 can be installed using a hinged mechanism with a locking structure, ensuring it is securely fixed to the circular channel pipe 25. When maintenance is required, maintenance personnel can easily access the tank 1 by opening the cover plate 22 through the notch 24. The operation is simple and quick, further enhancing the practicality and convenience of the fire water tank level monitoring and alarm device.

[0029] Please refer to Figure 1 and Figure 6 The housing 1 is equipped with a monitoring structure 4. The top of the other side is connected to a water inlet structure 3, and the front bottom is connected to a water outlet structure 5. The water inlet structure 3 includes an external threaded pipe 35. The top of the housing 1 is connected to a telescopic hose 36 through a connecting pipe 37. The top of the telescopic hose 36 is fixedly connected to an internal threaded pipe 38. The bottom end of the internal threaded pipe 38 is threadedly connected to an external threaded pipe 35. The top of the external threaded pipe 35 is threadedly connected to an L-shaped water inlet pipe 31. Several stacked filter screens 32 are installed inside the external threaded pipe 35.

[0030] The filter screen 32 can effectively filter impurities in the water entering the tank 1, preventing impurities from interfering with or damaging the water level monitoring structure 4 after entering the tank 1, thus ensuring the accuracy of water level monitoring and the normal operation of the device.

[0031] Please refer to Figure 1 and Figure 6 The telescopic hose 36 has a corrugated accordion shape in cross-section. The L-shaped inlet pipe 31 has internal threads that match the threads of the internal threaded pipe 38. This design allows for a tight connection between the L-shaped inlet pipe 31 and the internal threaded pipe 38, effectively preventing water leakage and ensuring the sealing of the inlet structure 3. Simultaneously, the corrugated accordion shape of the telescopic hose 36 provides excellent telescopic performance, allowing for flexible adjustment according to actual needs. When opening the external threaded pipe 35, hold the internal threaded pipe 38 and rotate the external threaded pipe 35. Simultaneously, the top of the external threaded pipe 35 unscrews from the L-shaped inlet pipe 31, and the bottom of the top of the external threaded pipe 35 is screwed deeper into the internal threaded pipe 38. The telescopic hose 36 supports the downward displacement of the internal threaded pipe 38. The entire disassembly process does not require the traditional removal of multiple pipes, making operation more convenient.

[0032] Please refer to Figure 1 and Figure 6The filter screen 32 has two symmetrically arranged perforated protrusions 33 fixedly connected to its outer wall. The inner wall of the externally threaded tube 35 has two symmetrically arranged elongated grooves 34, with the perforated protrusions 33 matching the grooves 34. When installing the filter screen 32, the perforated protrusions 33 on the outer wall of the filter screen 32 are inserted along the elongated grooves 34 on the inner wall of the externally threaded tube 35, allowing the filter screen 32 to be accurately installed in the designated position within the externally threaded tube 35. This design not only facilitates the installation and positioning of the filter screen 32 but also allows for convenient and quick removal of the filter screen 32 from the externally threaded tube 35 when it needs to be cleaned or replaced. The perforated protrusions 33 have pre-drilled threaded holes, and the elongated grooves 34 also have matching threaded holes. All filter screens 32 are installed by screwing in long bolts.

[0033] See Figure 2 and Figure 7 The monitoring structure 4 includes a main controller 41. The main controller 41 is installed on the front end of the housing 1. A U-shaped mounting plate 44 is fixedly connected to the rear end of the housing 1 near the bottom. An immersion pressure sensor 45 and a temperature sensor 46 are installed on the U-shaped mounting plate 44. A first buzzer 42 is installed on the top of the housing 1 near two opposite corners, and a second buzzer 43 is installed on the top near the other two opposite corners.

[0034] The main controller 41 is electrically connected to the submersible pressure sensor 45, the temperature sensor 46, the first buzzer 42, and the second buzzer 43. The submersible pressure sensor 45 monitors the water level and pressure in the fire water tank in real time and converts the pressure signal into an electrical signal, which is then transmitted to the main controller 41. The temperature sensor 46 monitors the temperature of the water in the fire water tank and also converts the temperature signal into an electrical signal, which is then transmitted to the main controller 41. When the water level and pressure detected by the submersible pressure sensor 45 exceed the set safety value, or when the water temperature detected by the temperature sensor 46 is below the normal range, the main controller 41 will immediately issue a command to control the first buzzer 42 and the second buzzer 43 to emit different alarm sounds to remind relevant personnel to take timely measures to ensure the normal operation of the fire water tank.

[0035] The main controller 41 is model STM32F103C8T6; the first buzzer 42 is model SFM-27; the second buzzer 43 is model HXD-12095; the submersible pressure sensor 45 is model MPM480; and the temperature sensor 46 is model DS18B20. The circuits and controls involved are existing technologies, and the top of the housing 1 has a reserved wiring hole, which allows the wiring to be connected normally.

[0036] When the temperature sensor 46 detects that the water temperature in the tank 1 is too low and ice forms, causing damage to internal components, it will quickly convert the low-temperature signal into an electrical signal and transmit it to the main controller 41. Upon receiving this abnormal signal, the main controller 41 will immediately activate the emergency response mechanism, controlling the second buzzer 43 to emit a rapid and distinctive alarm sound. This alarm sound is different from the alarm sound when the water level or pressure is abnormal, so that relevant personnel can quickly distinguish and locate the problem.

[0037] A submersible pressure sensor 45 is cleverly installed at a specific location in the fire water tank, accurately sensing the pressure exerted by the water inside the tank on the bottom of the sensor. As the water volume in the tank gradually increases, the pressure on the bottom of the sensor also increases accordingly. When this pressure reaches a pre-set pressure value corresponding to a suitable water volume, it indicates that the water volume in the tank 1 has reached the appropriate level. At this point, the submersible pressure sensor 45 quickly and accurately converts this pressure signal into an electrical signal and transmits it to the main controller 41 through a specific line, so that the main controller 41 can subsequently process and judge the received signal accordingly.

[0038] See Figure 2 and Figure 4 The water outlet structure 5 includes a water outlet pipe 51, and two symmetrically arranged sloping side plates 52 are fixedly connected to the bottom of the box body 1. A sloping center plate 53 is fixedly connected to the middle position of the two sloping side plates 52.

[0039] The ramp side plate 52 and the ramp center plate 53 together form a structure that guides the water flow, allowing the water in the tank 1 to flow more smoothly to the outlet pipe 51. One end of the outlet pipe 51 is connected to the inside of the tank 1, and the other end extends to the outside of the tank 1 to drain the water from the tank 1.

[0040] A water supply pipe is connected to the outlet pipe 51, and a control valve is installed on the water supply pipe. By opening and closing the control valve, the water discharge from the tank 1 can be flexibly controlled. When drainage is needed, the control valve is opened, and the water will flow along the guide structure formed by the slope side plate 52 and the slope center plate 53 under the action of gravity to the outlet pipe 51, and finally be discharged outside the tank 1. When drainage is not needed, the control valve is closed to stop the water from flowing out.

[0041] The U-shaped mounting plate 44 has two parallel elongated cavities 47, which facilitate the installation and adjustment of the entire device. During actual installation, relevant components can be flexibly fixed and repositioned through the elongated cavities 47 according to specific needs and site conditions, ensuring that the device can be stably and accurately installed in the appropriate position.

[0042] The height of the central plate 53 of the slope is lower than the height of the side plate 52 of the slope.

[0043] This design creates a natural drainage slope, allowing water in tank 1 to flow more smoothly along the slope to the outlet pipe 51, preventing water accumulation or stagnation inside the tank and improving drainage efficiency. Furthermore, any subsequent cleaning of sediment at the bottom of tank 1 can be guided by the slope, preventing backflow and making subsequent maintenance and cleaning work complex and cumbersome.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
