In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0014] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] Please refer to Figure 1The utility model discloses an automatic water replenishing device for a salt spray test chamber, comprising a box body 1, a water tank 2 is provided on one side of the box body 1, a slide bar 7 is fixedly connected to one side of the interior of the water tank 2, a floating block 8 is slidably connected to the slide bar 7, two dial plates 9 are rotatably connected to the inner wall of the water tank 2 at both ends of the slide bar 7, a touch switch 10 is fixedly connected to the position of the inner wall of the water tank 2 relative to the dial plate 9, a main switch 12 is connected to one side of the top of the floating block 8, a control panel 3 and an equipment alarm 4 are provided on the box body 1, and the touch switch 10 is electrically connected to the equipment alarm 4.

[0017] The box body 1 is located at the upper end of the water tank 2 and is connected to a water inlet pipe 5. The water inlet pipe 5 is provided with a solenoid valve 6. A drain pipe 11 is provided at the bottom of the water tank 2. The solenoid valve 6 is electrically connected to the control panel 3. A pull rope 13 is fixedly connected to the top of the floating block 8. The top of the pull rope 13 is connected to the gate rod of the main gate 12. A torsion spring is connected between the gate rod of the main gate 12 and the base. As the salt water in the water tank 2 increases, the floating block 8 floats up, and after the gate rod of the main gate 12 loses its downward pull, it is reset under the pull of the torsion spring, and the device is powered on. A torsion spring is sleeved on the rotating shaft of each dial plate 9. The gravity of the float 8 is greater than the thrust of the torsion spring of the dial plate 9, so the dial plate 9 is pushed onto the touch switch 10. The signal is transmitted to the control panel 3 through the touch switch 10 at the bottom. The solenoid valve 6 of the water inlet pipe 5 is controlled to open through the control panel 3, and salt water is re-injected into the water tank 2. The main gate 12 is electrically connected to the equipment alarm 4. When the main gate 12 is opened, the equipment alarm 4 is always turned on to remind the staff that the equipment is not turned off to avoid the equipment being started when not in use.

[0018] Specifically, when the utility model is used, before the device is used, the solenoid valve 6 is manually controlled to open, and the salt water required for the experiment is injected into the water tank 2 through the water inlet pipe 5. As the salt water in the water tank 2 increases, the float 8 floats up, and after the gate rod of the main gate 12 loses its downward pull, it is reset under the pull of the torsion spring, and the device is powered on. As the experiment proceeds, the salt water level in the water tank 2 drops. When the float 8 moves to the position of the bottom dial plate 9 as the liquid level drops, the gravity of the float 8 is greater than the thrust of the torsion spring of the dial plate 9, and the dial plate 9 is pushed onto the touch switch 10. The signal is transmitted to the control panel 3 through the touch switch 10 at the bottom, and the solenoid valve 6 of the water inlet pipe 5 is controlled to open through the control panel 3, and the salt water is injected into the water tank 2 again to avoid interruption of the experiment due to lack of water.

[0019] When the device needs to be shut down after use, first close the solenoid valve 6 through the control panel 3, then open the drain pipe 11 to drain the salt water in the water tank 2. After the float 8 drops to the bottom of the water tank 2, the pull rope 13 is straightened, and the gate rod of the main gate 12 is pulled open by the pull rope 13 to disconnect the power supply of the device to avoid shutting down directly without draining water and affecting the next experiment.

[0020] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0021] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
