However, during the cooling process, the coolant will be lost due to evaporation, splashing, etc. If it is not replenished in time, it will affect the cooling effect. However, in the water supply process of traditional cooling devices, usually workers hold tools such as funnels to manually fill water, or workers manually open the valve of the water inlet pipe to quickly replenish the coolant, but the replenishment amount of the coolant cannot be accurately controlled, which is easy to cause the coolant to overflow, thereby increasing the waste rate of resources. At the same time, manual operation is required, making the replenishment process of the coolant not flexible and convenient enough. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Refer to Figures 1 to 4As shown in the figure, the utility model provides a cooling device with automatic water supply based on Internet of Things control, including: a cooling tank 1, a water storage tank 5 is fixedly connected to the upper surface of the cooling tank 1, a water inlet pipe 15 and a PLC component 16 are respectively fixedly connected to the upper surface of the water storage tank 5, a liquid discharge port is opened at the bottom of the water storage tank 5, a guiding component 6 is fixedly connected in the liquid discharge port, a moving rod 9 is slidably connected inside the guiding component 6, a floating ball 3 is fixedly connected to the lower end of the moving rod 9, at the same time, a limiting ring 7 is fixedly connected to the lower end of the inner cavity of the water storage tank 5, trigger devices 8 are symmetrically connected to the upper surface of the limiting ring 7, infrared sensors 13 are symmetrically connected to the upper end of the inner cavity of the water storage tank 5, and guiding rods 10 are symmetrically connected to the inner cavity of the water storage tank 5. Guide holes are correspondingly opened on the surface of the floating plate 12 at positions corresponding to the guiding rods 10. The floating plate 12 is slidably connected in the water storage tank 5 through the guiding rods 10, and a water immersion sensor 14 is connected to the inner cavity of the water storage tank 5 at a position corresponding to the inner cavity of the guiding rod 10.

[0018] In this embodiment, when the liquid level of the coolant in the cooling tank 1 drops, the floating ball 3 will drive the moving rod 9 to move downward synchronously with the drop of the liquid level. Then, the liquid discharge port at the bottom of the water storage tank 5 is opened, and the coolant inside the water storage tank 5 can flow into the cooling tank 1 through the liquid discharge port. When the coolant inside the cooling tank 1 is replenished, the floating ball 3 will drive the moving rod 9 to move upward synchronously with the rise of the liquid level, so that the liquid discharge port is closed again, thereby ensuring that the coolant inside the cooling tank 1 is always at an appropriate stock level. As the coolant inside the water storage tank 5 is gradually discharged, the liquid level of the coolant inside the water storage tank 5 will also gradually drop, and the floating plate 12 will move downward synchronously with the drop of the liquid level until the lower surface of the floating plate 12 abuts against the upper surface of the limiting ring 7. The floating plate 12 will squeeze the trigger device 8, and the trigger device 8 will transmit the signal through the cable to the electrically connected PLC component 16. The PLC component 16 controls the opening of the solenoid valve electrically connected through the cable. Then, the coolant inside the water inlet pipe 15 can smoothly flow into the water storage tank 5. As the liquid level of the coolant inside the water storage tank 5 gradually rises, the floating plate 12 will also move upward synchronously under the action of buoyancy. Then, the floating plate 12 will first block the infrared sensor 13, and the infrared sensor 13 will transmit the signal through the cable to the electrically connected PLC component 16, and the PLC component 16 will control the closing of the solenoid valve of the water inlet pipe 15. If the line of the infrared sensor 13 fails and the PLC component 16 cannot identify the corresponding signal, the floating plate 12 will move upward further with the liquid level. At this time, the coolant inside the inner cavity of the guiding rod 10 will contact the electrode of the water immersion sensor 14, so that the water immersion sensor 14 can transmit the signal through the cable to the electrically connected PLC component 16, ensuring that the PLC component 16 can smoothly close the solenoid valve of the water inlet pipe 15 and prevent the coolant from being injected into the water storage tank 5. Therefore, through the cooperation of various sensors and corresponding structures, the cooling device can realize automatic water supply through the Internet of Things, enhancing the convenience and flexibility of the cooling device during actual use.

[0019] As a preferred embodiment, the cooling box 1 has a concave structure. One end of the bottom of the cooling box 1 close to the water storage tank 5 is fixedly connected with an auxiliary plate 2. The auxiliary plate 2 is integrally rectangular in structure, and the end faces at both ends of the auxiliary plate 2 are L-shaped. At the same time, the inclined surface of the auxiliary plate 2 faces the liquid discharge port opened in the water storage tank 5.

[0020] In this embodiment, as shown in Figure 1 and Figure 2 , the setting of the auxiliary plate 2 can prevent the sundries precipitated in the coolant from accumulating deep inside the cooling box 1, facilitating subsequent cleaning.

[0021] As a preferred embodiment, the cross plate 17 fixedly connected to the upper end of the inner cavity of the cooling box 1 is strip-shaped. The upper surface of the cross plate 17 is fixedly connected to the lower surface of the water storage tank 5. The cooling box 1 and the water storage tank 5 are combined to form an L-shaped structure. At the same time, the liquid discharge port opened at the bottom of the water storage tank 5 is circular, and the sealing ring 4 fixedly connected to the lower opening of the liquid discharge port is circular. The inner side surface of the sealing ring 4 is arc-shaped.

[0022] In this embodiment, as shown in Figure 1 , Figure 3 and Figure 4 , the setting of the cross plate 17 can assist in enhancing the stability of the connection between the cooling box 1 and the water storage tank 5. At the same time, the sealing ring 4 is made of soft rubber material, and the inner side surface of the sealing ring 4 fits the outer side surface of the floating ball 3, thereby being able to assist in enhancing the sealing effect when the floating ball 3 closes the liquid discharge port.

[0023] As a preferred embodiment, the limiting ring 7 fixedly connected inside the water storage tank 5 has a U-shaped structure. A set of triggers 8 are fixedly connected to the middle and the bent parts at both ends of the upper surface of the limiting ring 7. The three sets of triggers 8 are distributed in an isosceles triangle. At the same time, two sets of guide rods 10 fixedly connected to the inner cavity of the water storage tank 5 are located inside the limiting ring 7.

[0024] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the setting of the limiting ring 7 can effectively limit the falling range of the floating plate 12. When the coolant stock in the water storage tank 5 drops to the warning value, the floating plate 12 can timely press the trigger 8, enabling the PLC component 16 to timely open the solenoid valve of the water inlet pipe 15. At the same time, the three sets of triggers 8 are set at different positions to ensure that the PLC component 16 can receive the signals of at least one set of triggers 8, thereby opening the solenoid valve, enhancing the stability during the use of this cooling component. And the PLC component 16 can transmit the number of signals of the trigger 8 received in real time to the central control system (not shown in the figure) through the built-in wireless module, facilitating the workers to quickly confirm whether there is any damage to the trigger 8.

[0025] As a preferred embodiment, the guide rod 10 has a cylindrical structure. Multiple groups of through holes are axially and parallelly arranged at equal intervals at both ends of the guide rod 10. The outer diameter of the guide rod 10 is adapted to the diameter of the guide hole provided on the floating plate 12. At the same time, the length dimension of the floating plate 12 is adapted to the length dimension of the inner cavity of the water storage tank 5.

[0026] In this embodiment, as Figure 1 and Figure 2 , the size of the floating plate 12 is adapted to the inner cavity of the water storage tank 5, which can ensure that the lower surface of the floating plate 12 can cover the upper surface of the limit ring 7, ensuring that the trigger 8 can be triggered smoothly. At the same time, the size of the guide rod 10 is adapted to the guide hole, which can assist in enhancing the stability of the floating plate 12 during movement. The opening of the through holes enables the coolant to be injected into the guide rod 10, facilitating the water immersion sensor 14 to detect the height of the coolant level inside the water storage tank 5 in real time.

[0027] As a preferred embodiment, the floating plate 12 has a rectangular structure. The partition plate 11 fixedly connected to the middle of the lower surface of the floating plate 12 has an isosceles triangular prism structure, and the inside of the partition plate 11 is a hollow structure. The infrared sensor 13 and the partition plate 11 are in the same vertical plane.

[0028] In this embodiment, as Figure 1 and Figure 2 , the hollow structure of the partition plate 11 can effectively enhance the overall buoyancy of the combined component composed of the floating plate 12 and the partition plate 11. The setting of the partition plate 11 can ensure that the floating plate 12 can always block the infrared sensor 13 after moving up to the upper end of the water storage tank 5 with the liquid level, preventing the infrared sensor 13 from transmitting signals to the PLC component 16 multiple times.

[0029] As a preferred embodiment, the guide assembly 6 is composed of a guide cylinder and a fixing plate. The guide cylinder has a cylindrical structure. Four fixing plates are fixedly connected at equal intervals to the lower end of the outer arc surface of the guide cylinder. The four fixing plates are distributed in a cross shape. The moving rod 9 slidably connected to the inner cavity of the guide cylinder has a cylindrical structure. The axial cross-section of the moving rod 9 has a T-shaped structure. At the same time, the floating ball 3 fixedly connected to the lower end of the moving rod 9 has a spherical structure.

[0030] In this embodiment, as Figure 1 , Figure 3 and Figure 4 , the floating ball 3 is made of a hard material and has a hollow structure inside, which can enhance the buoyancy of the floating ball 3 in the coolant. Moreover, it is also convenient for the floating ball 3 to squeeze the sealing ring 4 under the action of buoyancy, enhancing the sealing effect of the floating ball 3 on the drain port. At the same time, the cooperation between the moving rod 9 and the guide assembly 6 enables the floating ball 3 to move up and down within a limited range, ensuring that the floating ball 3 can accurately close the drain port.

[0031] The automatic water supply cooling device based on Internet of Things control of the present utility model, through the cooperation of a floating ball 3, a guiding component 6, a moving rod 9, a floating plate 12, a trigger 8, an infrared sensor 13, a water immersion sensor 14 and a PLC component 16, enables the cooling device to have the function of automatic water supply, thereby ensuring that the coolant in the cooling tank 1 can always be in an appropriate amount, ensuring the cooling effect of the product, and also being able to assist in reducing the workload of workers. At the same time, the PLC component 16, the trigger 8, the infrared sensor 13 and the water immersion sensor 14 are all common brand models on the market and all have corresponding waterproof effects.
