[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. In the utility model, when the front end of the prism lens is submerged in water, the infrared rays emitted by the transmitting tube will be refracted in the water through the prism lens. When the infrared rays emitted by the transmitting tube are refracted in the water, the receiving tube will not receive the infrared rays. When the receiving tube cannot receive the infrared rays, the infrared sensor will not generate a connection signal, thereby indicating that the water tank is not short of water. At the same time, when the front end of the prism lens is short of water, the infrared rays emitted by the transmitting tube will be reflected back to the front end of the infrared sensor through the prism lens and received by the receiving tube. When the receiving tube receives the infrared rays reflected by the prism lens, the infrared sensor can send a connection signal to the infrared signal processor. When the infrared signal processor receives the connection signal of the infrared sensor, it can control the sound and light alarm to start the sound and light alarm of the water tank short of water, thereby realizing the water level short of water monitoring alarm inside the water tank through the optical reflection principle, and there is no need to install the sensor head inside the water tank;
[0017] 2. The utility model also pulls the spring locating pin outwards through the pull ring. When the spring locating pin is pulled outwards, the pin column part at the front top of the spring locating pin will move outwards from the inner wall of the locating hole. When the pin column part at the front top of the spring locating pin moves outwards from the inner wall of the locating hole, the moving block will no longer remain locked and fixed. When the moving block is no longer locked and fixed, the moving block is pushed upwards to move straightly upwards along the inner wall of the limiting straight slide groove. When the moving block moves straightly upwards, it will drive the infrared sensor to move straightly upwards. When the infrared sensor moves straightly upwards, it can play a role in adjusting the infrared sensor to monitor the water level height inside the water tank, thereby realizing the water level shortage monitoring and alarm inside the water tank, and facilitating the adjustment of the water level height inside the water tank.

[0025] A water level groove 5 is provided on the outside of the water tank 1, and a monitoring port 6 is provided through the lower end of the water level groove 5, and there are several monitoring ports 6, which are vertically symmetrically distributed in sequence at the lower end of the water level groove 5. A prism lens 7 is fixedly installed on the inner side of the monitoring port 6, and the prism lens 7 is made of a transparent material component. Limited straight slide grooves 8 are provided on both sides of the inner wall of the water level groove 5, and there are two limited straight slide grooves 8, which are symmetrically distributed on both sides of the inner wall of the water level groove 5. A moving block 9 is movably connected to the inner wall of the limited straight slide groove 8, and an infrared sensor 10 is threadedly connected to the middle of the moving block 9. An emitting tube 101 for generating infrared rays and a receiving tube 102 for receiving infrared rays are fixedly installed on the upper and lower sides of the front top of the infrared sensor 10, respectively, and the front top of the infrared sensor 10 is on the same horizontal line as the inner side of the rear end of the prism lens 7, so that the water level inside the water tank 1 is infraredly monitored by the infrared sensor 10 in cooperation with the prism lens 7, and a positioning hole 11 is provided on the outer side of the lower end of the water level groove 5, and there are several positioning holes 11. , respectively, they are vertically symmetrically distributed on the outer side of the lower end of the water level groove 5, pin holes 12 are opened on both sides of the rear top of the moving block 9, and the pin holes 12 are on the same horizontal line as the positioning hole 11, the inner wall of the pin hole 12 is fitted and movably connected with a spring positioning pin 13, and the spring part of the outer end of the spring positioning pin 13 is fixedly installed on the two side surfaces of the rear top of the moving block 9, and the pin column part of the front top of the spring positioning pin 13 passes through the pin hole 12 and is fitted and movably connected to the inner wall of the positioning hole 11, so that the moving block 9 is locked and limited by the spring positioning pin 13 in conjunction with the pin hole 12 and the positioning hole 11, and a pull ring 14 is fixedly installed on the outer top of the spring positioning pin 13, and an infrared signal processor 15 and an audible and visual alarm 16 are fixedly installed on the outer side of the upper end of the water tank 1, and the infrared signal processor 15 is electrically connected to the infrared sensor 10 and the audible and visual alarm 16 through wires, so that the water level signal of the water tank 1 monitored by the infrared sensor 10 is processed by the infrared signal processor 15 and the opening of the audible and visual alarm 16 is controlled.
[0026] Working principle: When in use, when the infrared sensor 10 cooperates with the prism lens 7 to perform infrared monitoring on the water level inside the water tank 1, the transmitting tube 101 will emit infrared rays forward. When the front end of the prism lens 7 is submerged in water, the infrared rays emitted by the transmitting tube 101 will be refracted in the water through the prism lens 7. When the infrared rays emitted by the transmitting tube 101 are refracted in the water, the receiving tube 102 will not receive the infrared rays. When the receiving tube 102 does not receive the infrared rays, the infrared sensor 10 will not generate a connection signal, thereby indicating that the water tank 1 is not short of water. At the same time, when the front end of the prism lens 7 is in a state of water shortage, the infrared rays emitted by the transmitting tube 101 will be reflected back to the front end of the infrared sensor 10 through the prism lens 7 and pass through. The infrared sensor 10 receives the infrared rays reflected by the prism lens 7 through the receiving tube 102. When the receiving tube 102 receives the infrared rays reflected by the prism lens 7, the infrared sensor 10 can send a connection signal to the infrared signal processor 15. When the infrared signal processor 15 receives the connection signal of the infrared sensor 10, it can control the sound and light alarm 16 to sound and light alarm when the water tank 1 is short of water. Thus, the water level shortage monitoring alarm of the water tank 1 is realized through the optical reflection principle, and the sensing head does not need to be installed in the water tank 1. This avoids the problem that when the sensing head part for monitoring the water level is installed in the water tank 1 for a long time, the sensing head part is easy to be polluted by residual dirt and the water quality inside the water tank 1 is polluted. At the same time, it is not convenient to inspect and maintain the sensing head part.
[0027] At the same time, the spring locating pin 13 is pulled outward by the pull ring 14. When the spring locating pin 13 is pulled outward, the pin column part at the front top of the spring locating pin 13 will move outward from the inner wall of the locating hole 11. When the pin column part at the front top of the spring locating pin 13 moves outward from the inner wall of the locating hole 11, the moving block 9 will no longer remain locked and fixed. When the moving block 9 is no longer locked and fixed, the moving block 9 is pushed upward and moves straightly upward along the inner wall of the limiting straight slide groove 8. When the moving block 9 moves straightly upward, it will drive the infrared sensor 10 to move straightly upward. When the infrared sensor 10 moves straightly upward, it can play the role of adjusting the infrared sensor 10 to monitor the water level height inside the water tank 1, thereby realizing the water level shortage monitoring and alarm inside the water tank 1, and facilitating the adjustment and monitoring of the water level height inside the water tank 1.
