[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Refer to Figure 2 - Figure 4, an embodiment provided by the present utility model: a water shortage self-stop alarm device for secondary water supply equipment, including a box body 1. The sturdy box body 1 provides a safe and stable installation environment for each component inside, effectively preventing external factors from interfering with and damaging the device, ensuring that the entire device can operate reliably for a long time. On the right side of the top of the box body 1, there is a switch assembly that is convenient for maintenance. This design provides a convenient entrance for subsequent maintenance operations, enabling maintenance personnel to easily open the device for inspection and maintenance work. The switch assembly includes two fixed blocks 2. The bottom ends of the two fixed blocks 2 are fixedly connected to the right side of the top of the box body 1. On the adjacent sides of the two fixed blocks 2, there is a rotating connection with an opening cover 3. The stable connection of the fixed blocks 2 ensures that the opening cover 3 can rotate and open and close stably, without loosening or falling off, providing a reliable opening and closing structure for the maintenance passage of the device. On the top of the opening cover 3, there is a fixedly connected handle 4, which is convenient for maintenance personnel to apply force to open the cover. The bottom end of the opening cover 3 is slidably connected to the right side of the top of the box body 1. On the left side inside the box body 1, there is a fixedly connected support plate 5, which provides additional support. Inside the top of the support plate 5, there is a rotating connection with a lever 6, which can rotate flexibly according to the water level change. On the left and right sides of the top of the lever 6, there are fixedly connected contact blocks 7, which can accurately contact other components under the rotation of the lever 6 to effectively judge the water level state and perform corresponding control. On the right side of the bottom end of the lever 6, there is a sliding groove 8, and a sliding rod 9 is movably connected to the sliding groove 8, enabling the slight change of the water level to be effectively transmitted to the lever 6 through the movement of the sliding rod 9, thereby triggering corresponding actions. At the bottom end outside the sliding rod 9, there is a fixedly connected floating plate 10, which can float freely with the rise and fall of the water level, accurately sense the change of the water level, and transmit this change to the lever 6 through the sliding rod 9. At the bottom end of the sliding rod 9, there is a fixedly connected counterweight 11, making the floating of the floating plate 10 more stable, thereby improving the accuracy of water level detection;
[0026] Inside the box body 1, a water tank 12 is fixedly connected to provide a storage space for secondary water supply. At the top left inside the water tank 12, a limiting block 13 is fixedly connected. The outer part of the sliding rod 9 is slidably connected to the top left inside of the water tank 12. The outer part of the floating plate 10 is slidably connected inside the limiting block 13, which can limit the moving range of the floating plate 10, prevent its excessive movement, and ensure the accuracy and reliability of water level detection. At the right end of the water tank 12, a transmission pipe 14 is fixedly connected, which can be used to input and output water. The outer part of the transmission pipe 14 is fixedly connected to the left inside of the box body 1. A water shortage transmission block 15 is slidably connected to the left side of the box body 1. When the water level drops to a certain extent, the left contact block 7 can contact the water shortage transmission block 15 to trigger a water shortage alarm signal in time. The top of the left contact block 7 contacts the right side of the water shortage transmission block 15. An alarm block 16 is fixedly connected to the left side of the box body 1, which can quickly emit an obvious alarm signal when there is a water shortage or the water is full, reminding relevant personnel to take measures in time. A water stop transmission block 17 is detachably connected to the top of the box body 1. The detachable connection here is the same as the replacement operation of the water shortage transmission block 15. The top of the right contact block 7 contacts the bottom of the water stop transmission block 17. When the water level is too high, the right contact block 7 contacts the water stop transmission block 17 to realize the control of stopping water supply.
[0027] Referring to Figure 1 and Figure 5 , a threaded rod 18 is threadedly connected to the left inside of the box body 1, enabling the threaded rod 18 to be stably installed therein, providing a solid foundation for subsequent transmission operations. The outer part of the threaded rod 18 is threadedly connected to a moving block 19, so that when the threaded rod 18 rotates, it can accurately drive the moving block 19 to move along a predetermined direction. Inside the adjacent sides of the two moving blocks 19, a connecting rod 20 is rotatably connected, realizing the flexible transmission of force and the conversion of direction. On the adjacent sides of the two connecting rods 20, a clamping block 21 is rotatably connected, enabling the clamping block 21 to make corresponding adjustments according to the movement of the moving block 19. Two moving holes 22 are opened in the left inside of the box body 1. The right end of the threaded rod 18 is rotatably connected to the inside of one side of the moving hole 22. The outer part of the moving block 19 is slidably connected to the inside of the moving hole 22, providing a standard channel for the movement of the moving block 19 and the clamping block 21, ensuring that their movement trajectories are accurate. One side of the clamping block 21 is slidably connected to the inside of the moving hole 22. The left side of the threaded rod 18 is fixedly connected to a rotating disk 23, and the right side of the rotating disk 23 is rotatably connected to the left side of the box body 1.
[0028] Working principle: When the water level in the water tank 12 drops, the floating plate 10 will move downward under the gravity of the counterweight 11, and then drive the sliding rod 9 to slide down, causing the right end of the lever 6 to sink and the left end to rise. The left contact block 7 will contact the water shortage transmission block 15 when it rises to a certain position, and then trigger the alarm block 16 to issue a water shortage alarm. When the water level rises too high, the floating plate 10 will drive the counterweight 11 to move upward, causing the right end of the lever 6 to rise and the left end to sink. When the lever 6 rises, the contact block 7 at the right end will rise accordingly. After rising to a certain position, it will contact the water stop transmission block 17, and then trigger the alarm block 16 to issue a water stop alarm.
[0029] When it is necessary to replace the water shortage transmission block 15, first rotate the rotating disc 23. Under the rotation of the rotating disc 23, the thread of the threaded rod 18 will move, causing the moving block 19 to move outside the threaded rod 18. Then, when the moving block 19 slides inside the moving hole 22, it will drive the connecting rod 20 to move. Then, under the movement of the connecting rod 20, the engaging block 21 will be separated from the card slot inside the water shortage transmission block 15. At this time, the water shortage transmission block 15 is not restricted by anything, and then it can be taken out and replaced. The detachable connection of the water stop transmission block 17 is the same as the replacement principle of the water shortage transmission block 15.
[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
