[0022] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0023] This utility model provides a forklift water wading alarm device, such as Figure 2 As shown, it includes a starting battery 3, a buzzer 2, and a wading alarm 1. The wading alarm 1 is connected to the starting battery 3 and the buzzer 2 via wires. The starting battery 3 provides power to the entire vehicle's electrical system (including the wading alarm device). When the forklift wades through deep water, the wading alarm 1 outputs a 12V operating voltage. The buzzer 2 is connected to the wading alarm 1 and, upon receiving the operating voltage from the wading alarm 1, emits an audible alarm.

[0024] The positive and negative terminals of the wading alarm 1 are connected to the positive and negative terminals of the starting battery 3. The source terminal (S) of the wading alarm 1 is connected to the positive terminal of the buzzer 2, and the negative terminal of the buzzer 2 is connected to the negative terminal of the starting battery 3. The starting battery 3 powers the entire system circuit. When the wading alarm 1 senses water, its source terminal outputs 12V, which is transmitted to the positive terminal of the buzzer 2. The buzzer 2 then continuously sounds the alarm. Conversely, when there is no water, the source terminal of the wading alarm 1 has no output voltage. The buzzer 2 is not powered and therefore does not sound.

[0025] In this embodiment, the starting battery 3 is a 12V starting battery.

[0026] like Figure 3 , Figure 4 As shown, the water wading alarm 1 consists of an electrical module 13, a mounting bracket 12, a double-layer mesh tube 14, a rubber plug 16, a sealing ring 15, and a fastening nut 11. The water wading alarm 1 is fixed to the front and rear ends of the forklift frame via the mounting bracket 12. The double-layer mesh tube 14, rubber plug 16, and sealing ring 15 provide a sealed environment for the electrical module 13, preventing accidental water ingress and false alarm triggering. The fastening nut 11 secures all the components of the water wading alarm 1 together.

[0027] The specific structure is as follows: The electrical module 13 has a convex shape, consisting of a small block and a large block. One end of the double-layer mesh tube 14 has an open end, and the other end has a small opening. The electrical module 13 is housed within the double-layer mesh tube 14. The small block of the electrical module 13 passes sequentially through the small opening of the double-layer mesh tube 14 and the through hole on the mounting bracket 12, and is threadedly connected to the outside of the small block of the electrical module 13 by a fastening nut 11. The open end of the double-layer mesh tube 14 is sealed by a rubber plug 16. A sealing ring 15 is provided between the inside of the small opening of the double-layer mesh tube 14 and the large block. The small block of the electrical module 13 matches the small opening of the double-layer mesh tube 14, the through hole on the mounting bracket 12, and the sealing ring 15. The maximum outer diameter of the large block is larger than the maximum outer diameter of the small block.

[0028] The double-layer network pipe 14 consists of a double-layer network pipe upper sealing plate 141, a double-layer network pipe inner pipe 142, and a double-layer network pipe outer pipe 143. The double-layer network pipe inner pipe 142 is located inside the double-layer network pipe outer pipe 143, and a gap is provided between the double-layer network pipe inner pipe 142 and the double-layer network pipe outer pipe 143. The top of both the double-layer network pipe inner pipe 142 and the double-layer network pipe outer pipe 143 are connected to the double-layer network pipe upper sealing plate 141. The double-layer network pipe upper sealing plate 141 has a small opening for the small block of the electrical module 13 to pass through. Small holes are opened on the upper and lower sides of the double-layer network pipe inner pipe 142 and the double-layer network pipe outer pipe 143. The lower hole is a water inlet 19, and the upper hole is a vent 17, so as to ensure that the air in the pipe can be discharged in time when water enters through the water inlet 19.

[0029] The bottom of the electrical module 13 is connected to a liquid detection module 18, which is positioned above the small holes on the inner tube 142 and the outer tube 143 of the double-layer mesh pipe.

[0030] In this embodiment, the bottom of the liquid detection module 18 is located at the higher of the small holes on the inner tube 142 and the outer tube 143 of the double-layer mesh tube.

[0031] Small holes are provided on the side walls of the inner tube 142 and the outer tube 143 of the double-layer mesh tube near the bottom and near the top, and the positions of the small holes on the inner tube 142 and the outer tube 143 of the double-layer mesh tube are staggered.

[0032] In this embodiment, the small holes of the inner tube 142 and the outer tube 143 of the double-layer mesh tube are staggered by 90° around the circumference. This arrangement ensures that in case of rain or splashing water, water can enter the outer tube through the small holes of the outer tube 143 but not the inner tube 142. This ensures the dryness of the inner tube 142 and the accuracy of the electrical module 13's detection. A sealing ring 15 is installed between the inside of the double-layer mesh tube 14 and the electrical module 13 to prevent moisture from seeping into the inside of the double-layer mesh tube 14 from above.

[0033] When installing the water alarm 1, cover the upper part of the electrical module 13 with the liquid detection module 18 at the bottom with the sealing ring 15, pass the electrical module 13 under the double-layer mesh tube 14 and through the mounting bracket 12, and then tighten it with the fastening nut 11. Finally, use the rubber plug 16 to seal the double-layer mesh tube 14.

[0034] When wading through water, water first enters the double-layer mesh pipe 143 through the inlet 19 below the outer pipe 143, then enters the inner pipe 142 through the inlet 19 below the inner pipe 142, and finally the water comes into contact with the liquid detection module 18 at the bottom of the electrical module 13. When the liquid detection module 18 comes into contact with the water, the buzzer 2 immediately sounds an alarm.

[0035] When the water alarm 1 is accidentally damaged or the double-layer network tube 14 is clogged and needs cleaning and maintenance, the rubber plug 16 can be removed and then it can be cleaned and maintained, or the electrical module 13 can be replaced.

[0036] like Figure 1 As shown, the electrical module 13 integrates a liquid detection module 18, an A / D conversion module, an execution module, a step-down module, and a main control module. The step-down module, liquid detection module 18, A / D conversion module, main control module, and execution module are connected sequentially. The step-down module is also connected to both the main control module and the execution module. When the liquid detection module 18 detects moisture, the execution module outputs a 12V operating voltage. The working principle of the electrical module 13 is as follows:

[0037] The external starting battery 3 first outputs a stable voltage to the electrical module 13 through a step-down module, enabling it to operate normally. Then, when the liquid detection module 18 detects liquid, it outputs a stable and continuous voltage, which is then converted from analog to digital by an A / D converter and fed back to the main control module. Upon receiving the signal, the main control module transmits it to the execution module, which outputs a stable 12V operating voltage—the 12V output at the S-stage of the water wading alarm 1. Conversely, when the liquid detection module 18 does not detect liquid, it outputs zero voltage, which is then converted back to digital by the A / D converter and fed back to the main control module. Upon receiving this signal, the main control module transmits it to the execution module, which does not output voltage; that is, the S-stage of the water wading alarm 1 does not output voltage and remains in a high-impedance state.

[0038] like Figure 5 As shown, the installation process of this utility model on a forklift is as follows:

[0039] Two wading alarms 1 are placed at the front and rear ends of the forklift, respectively. A buzzer 2 is fixed to the front end of the forklift, and a starting battery 3 is fixed to the frame. When the forklift moves forward, if the wading depth exceeds the front wading alarm 1, the wading alarm 1 detects moisture, and the buzzer 2 sounds an alarm. When the forklift reverses, if the wading depth exceeds the rear wading alarm 1, the wading alarm 1 detects moisture, and the buzzer 2 sounds an alarm.
