[0019] A method for using a water immersion sensor comprises the following steps:

[0020] S1. When assembling the device, the staff manually moves the buzzer downward to dock with the mounting seat, and inserts the sealing ring at the lower end of the buzzer into the sealing groove. At this time, the trigger rod on the upper accommodating chamber will contact the lower limiting plate, and the trigger rod in the lower accommodating chamber will contact the upper limiting plate. At this time, since the two trigger rods are in contact with the lower limiting plate and the upper limiting plate, as the buzzer continues to move downward, the upper limiting plate and the lower limiting plate are squeezed to rotate by the setting of the trigger rod, so that the two trigger rods are respectively stuck in the inner grooves of the upper limiting plate and the lower limiting plate. When the two limiting plates rotate, the tension spring will be pulled. After the trigger rod is stuck in the inner groove, the upper limiting plate and the lower limiting plate are reset by the tension spring. At this time, the buzzer is connected to the mounting seat;

[0021] S2. At the same time, due to the rotation of the upper limiting plate, the upper limiting plate drives the positioning rod to rotate through the transmission rod, and the positioning rod drives the upper lever to rotate sideways. Since the upper lever and the lower lever are connected by a tension spring, when the upper lever moves to the limit position, it drives the lower lever to deflect in the same direction. The deflection of the lower lever can push the airtight block to move in the air chamber, squeeze the air, and allow the air to enter the sealing strip through the air outlet hole;

[0022] S3. Since the sealing groove is an I-shaped structure, when the buzzer and the mounting base are connected, the airtight block moves to squeeze air into the sealing strip, causing the sealing strip to expand and completely embed into the sealing groove, thereby increasing the sealing performance of the connection.

[0023] S4. Next, the staff manually inserts the cable head into the plug-in bin, and the cable head contacts the front end of the trigger column. At this time, the limit column and the deep hole are staggered, so that the cable head synchronously drives the trigger column to move forward, and the trigger column drives the movable block to move forward. The toothed plate on the movable block drives the driven wheel to rotate through the driving gear, and the driven wheel drives the toggle wheel to rotate, so that the toggle wheel releases the obstruction of the cable head. Then, when the trigger column moves to the deep hole, the limit column continuously enters the deep hole through the setting of the spring and the baffle, driving the trigger column to move backward until the trigger column and the cable head are released from contact. At this time, the movable block is reset by the telescopic spring rod, and the toothed plate on the movable block once again drives the toggle wheel to reset in the opposite direction. At this time, the cable head is squeezed forward by the toggle wheel to lock the cable head.

[0024] S5. Finally, the staff manually presses down the dial plate, and the dial plate pushes the lower pressure plate. The lower pressure plate pushes the driven wheel to rotate through the rack. The driven wheel drives the dial wheel to rotate clockwise, and the dial wheel releases the restriction on the cable head. At this time, the cable head can be pulled out, and the cable head moves backward to squeeze the trigger column. Since the trigger column is a wedge block structure and the round rod is a spring telescopic rod structure, the trigger column is squeezed and moved sideways, so that the cable head can be moved out of the device for quick disassembly.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In the present invention, by providing two accommodating chambers and two limiting plates in the installation mechanism, the buzzer and the mounting base can be quickly locked when docked, which is convenient for staff to install and disassemble, and convenient for staff and users to replace and install components.

[0027] In the present invention, by setting the sealing member, gas can be squeezed into the buzzer and the mounting seat when the buzzer and the mounting seat are installed, so that the sealing strip expands and fits the sealing groove, thereby increasing the sealing effect and further strengthening the connection between the buzzer and the mounting seat.

[0028] In the present invention, by setting the paddle plate and the lower pressure plate, when the lower pressure plate is simply paddled, the installation of the cable at the current position can be released. When the paddle plate is directly pressed, all the lower pressure plates can be squeezed and unlocked at the same time, which is convenient for the staff to quickly remove the cables.

[0057] In this embodiment, Figures 1 to 11 As shown, a method for using a water immersion sensor includes the following steps:

[0058] S1. The staff can install the device on the wall or the ground with bolts and connect it with the mobile phone through the Bluetooth module body to facilitate the staff to control the operation of the device;

[0059] When assembling the device, the buzzer 2 is manually moved downward to dock with the mounting base 1, and the sealing ring at the lower end of the buzzer 2 is inserted into the sealing groove 398. At this time, the trigger rod 34 on the upper accommodating chamber 36 will contact the lower limiting plate 32, and the trigger rod 34 in the lower accommodating chamber 31 will contact the upper limiting plate 37. At this time, since the two trigger rods 34 are in contact with the lower limiting plate 32 and the upper limiting plate 37, as the buzzer 2 continues to move downward, the upper limiting plate 37 and the lower limiting plate 32 are squeezed by the setting of the trigger rod 34 to rotate, causing the two trigger rods 34 to be respectively stuck in the inner grooves 33 in the upper limiting plate 37 and the lower limiting plate 32. When the two limiting plates rotate, the tension spring will be pulled. After the trigger rod 34 is stuck in the inner groove 33, the upper limiting plate 37 and the lower limiting plate 32 are reset by the tension spring. At this time, the buzzer 2 is connected to the mounting base 1;

[0060] S2. At the same time, due to the rotation of the upper limiting plate 37, the upper limiting plate 37 drives the positioning rod 392 to rotate through the transmission rod 38, and the positioning rod 392 drives the upper lever 393 to rotate sideways. Since the upper lever 393 and the lower lever 394 are connected by a tension spring, when the upper lever 393 moves to the limit position, it drives the lower lever 394 to deflect in the same direction. The deflection of the lower lever 394 can push the airtight block 397 to move in the air chamber 395, squeezing the air so that the air enters the sealing strip 399 through the air outlet hole.

[0061] S3. Since the sealing groove 398 is an I-shaped structure, when the buzzer 2 and the mounting base 1 are connected, the air is squeezed into the sealing strip 399 through the movement of the airtight block 397, so that the sealing strip 399 expands and the sealing strip 399 is completely embedded in the sealing groove 398, thereby increasing the sealing performance of the connection;

[0062] S4. Next, the staff manually inserts the cable head into the plug-in bin 41, and the cable head contacts the front end of the trigger column 46. At this time, the limit column 45 and the deep hole 412 are staggered, so that the cable head synchronously drives the trigger column 46 to move forward, and the trigger column 46 drives the movable block 42 to move forward. The toothed plate 47 on the movable block 42 drives the driven wheel 49 to rotate through the driving gear 48, and the driven wheel 49 drives the toggle wheel 410 to rotate, so that the toggle wheel 410 releases the obstruction of the cable head. Then, when the trigger column 46 moves to the deep hole 412, the limit column 45 continuously enters the deep hole 412 through the setting of the spring and the baffle 44, and drives the trigger column 46 to move backward until the trigger column 46 is released from the contact state with the cable head. At this time, the movable block 42 is reset by the telescopic spring rod 43, and the toothed plate 47 on the movable block 42 once again drives the toggle wheel 410 to reset in the opposite direction. At this time, the cable head is squeezed forward by the toggle wheel 410 to lock the cable head;

[0063] S5. Finally, the staff manually presses down the dial plate 416, and the dial plate 416 pushes the lower pressure plate 414. The lower pressure plate 414 pushes the driven wheel 49 to rotate through the rack 415. The driven wheel 49 drives the dial wheel 410 to rotate clockwise. The dial wheel 410 releases the restriction on the cable head. At this time, the cable head can be pulled out, and the cable head moves backward to squeeze the trigger column 46. Since the trigger column 46 is a wedge block structure and the round rod is a spring telescopic rod structure, the trigger column 46 is squeezed and moved sideways, so that the cable head can be moved out of the device for quick disassembly.

4. The method for using a water immersion sensor according to claim 3, characterized in that: The steps include: S1. When assembling the device, the staff manually moves the buzzer (2) downward to dock with the mounting base (1), and inserts the sealing ring at the lower end of the buzzer (2) into the sealing groove (398). At this time, the trigger rod (34) on the upper receiving chamber (36) will contact the lower limiting plate (32), and the trigger rod (34) in the lower receiving chamber (31) will contact the upper limiting plate (37). At this time, because the two trigger rods (34) are in contact with the lower limiting plate (32) and the upper limiting plate (37), the buzzer (2) continues to move downward, so that The upper limiting plate (37) and the lower limiting plate (32) are pressed to rotate by the setting of the trigger rod (34), so that the two trigger rods (34) are respectively inserted into the inner grooves (33) in the upper limiting plate (37) and the lower limiting plate (32). When the two limiting plates rotate, the tension spring is pulled. After the trigger rod (34) is inserted into the inner groove (33), the upper limiting plate (37) and the lower limiting plate (32) are reset by the tension spring. At this time, the buzzer (2) is connected to the mounting seat (1). S2. At the same time, as the upper limiting plate (37) rotates, the upper limiting plate (37) drives the positioning rod (392) to rotate through the transmission rod (38), and the positioning rod (392) drives the upper lever (393) to rotate sideways. Since the upper lever (393) and the lower lever (394) are connected by a tension spring, when the upper lever (393) moves to the limit position, it drives the lower lever (394) to deflect in the same direction. The deflection of the lower lever (394) can push the airtight block (397) to move in the air chamber (395), squeeze the air, and allow the air to enter the sealing strip (399) through the air outlet hole; S3. Since the sealing groove (398) is arranged in an I-shaped structure, when the sealing strip (399) is connected to the buzzer (2) and the mounting seat (1), the airtight block (397) moves to squeeze air into the sealing strip (399), so that the sealing strip (399) expands and the sealing strip (399) is completely embedded in the sealing groove (398), thereby increasing the sealing performance of the connection; S4. Next, the staff manually inserts the cable head into the plug-in compartment (41), and the cable head contacts the front end of the trigger column (46). At this time, the limit column (45) and the deep hole (412) are staggered, so that the cable head synchronously drives the trigger column (46) to move forward, and the trigger column (46) drives the movable block (42) to move forward. The toothed plate (47) on the movable block (42) drives the driven wheel (49) to rotate through the driving gear (48), and the driven wheel (49) drives the toggle wheel (410) to rotate, so that the toggle wheel (410) releases the blocking of the cable head. Then, when the trigger column (46) moves to the deep hole (412), the limit column (45) continuously enters the deep hole (412) through the setting of the spring and the baffle (44), driving the trigger column (46) to move backward until the trigger column (46) and the cable head are no longer in contact. At this time, the movable block (42) is reset through the telescopic spring rod (43), and the toothed plate (47) on the movable block (42) once again drives the toggle wheel (410) to reset in the opposite direction. At this time, the cable head is squeezed forward by the toggle wheel (410) to lock the cable head. S5. Finally, the staff manually presses down the dial plate (416), and the dial plate (416) pushes the lower pressing plate (414). The lower pressing plate (414) pushes the driven wheel (49) to rotate through the rack (415). The driven wheel (49) drives the dial wheel (410) to rotate clockwise. The dial wheel (410) releases the restriction on the cable head. At this time, the cable head can be pulled out, and the cable head moves backward to squeeze the trigger column (46). Due to the wedge block structure of the trigger column (46) and the round rod being a spring telescopic rod structure, the trigger column (46) is squeezed and moved sideways, so that the cable head can be moved out of the device for quick disassembly.
