Description

Automatic water tank level control device Technical Field

[0001] This utility model belongs to the field of water tank level control technology, specifically relating to an automatic water tank level control device. Background Technology

[0002] In practical production and daily life, it is often necessary to control the liquid level in water tanks. In related technologies, water tank level control methods mainly involve a level gauge and a valve forming a control loop. If the liquid level in the tank is higher than a specified value, the valve is closed to stop the liquid inflow. If the liquid level is lower than the specified value, the valve is opened to replenish the tank. However, when the tank is filled with liquid, the liquid surface is extremely unstable due to the impact of the water flow. When the liquid level approaches the specified value, the surface fluctuations cause the liquid level to fluctuate around the specified value, resulting in frequent valve opening and closing, thus reducing the service life of the valve. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide an automatic water tank level control device, which helps to improve service life and level control accuracy.

[0004] The automatic water tank level control device of this utility model embodiment includes: a water tank, the water tank including a first cavity and a second cavity arranged sequentially in a horizontal direction, wherein water in the first cavity can overflow from its top into the first cavity; a water inlet pipe, the water inlet pipe being disposed at the top of the water tank, and the outlet of the water inlet pipe being located above the first cavity; a first control component, the first control component being used to control the water inlet pipe to stop supplying liquid into the first cavity when the liquid level in the second cavity is higher than a first preset height, and to control the water inlet pipe to supply liquid into the first cavity when the liquid level in the second cavity is lower than a second preset height, wherein the first control component is used to control the water inlet pipe to stop supplying liquid into the first cavity. A second preset height is lower than the first preset height; a connecting pipe, the connecting pipe extending horizontally, one end of the connecting pipe connecting to the first cavity, and the other end of the connecting pipe connecting to the second cavity; a second control element, the second control element being used to control the connecting pipe to connect the first cavity and the second cavity when the liquid level in the first cavity is lower than the third preset height, and to control the connecting pipe to disconnect the connection between the first cavity and the second cavity when the liquid level in the first cavity is higher than the fourth preset height, the fourth preset height being higher than the third preset height and lower than the second preset height.

[0005] It should be noted that when filling the tank with water, the inlet pipe is opened, and water can be poured into the first chamber through the inlet pipe. Once the first chamber is full, water continues to be poured into it through the inlet pipe. Water in the first chamber can overflow into the second chamber. When the overflowing water level in the second chamber is higher than a first preset height, the first control unit stops the inlet pipe from filling the first chamber. When draining water from the first chamber, when the water level in the first chamber is lower than a third preset height, the second control unit connects the first and second chambers through the connecting pipe. Since the water level in the second chamber is higher than the first preset height... The liquid level in the first chamber is controlled so that water in the second chamber can flow into the first chamber through the connecting pipe. When the liquid level in the second chamber is lower than the second preset height, the first control unit controls the water inlet pipe to open and fill the first chamber with liquid. This achieves control of the water level in the water tank, eliminating the need to frequently start the water inlet pipe to fill the water tank, which helps to improve the service life. It also allows for timely control of the water inlet pipe to replenish water when the water level in the water tank is low. Furthermore, the water replenishment to the second chamber is achieved through the overflow of the first chamber, so the liquid level in the second chamber is less affected by the impact of the water flow, which helps to improve the accuracy of liquid level control.

[0006] In this embodiment, the water tank includes a tank body and a partition vertically disposed within the tank body. The partition divides the tank body into a first cavity and a second cavity, and the top height of the partition is lower than the side wall height of the tank body.

[0007] In this embodiment, the connecting pipe is located at the lower part of the partition.

[0008] In this embodiment, the water tank further includes a cover plate, which is detachably disposed on the top of the tank body.

[0009] In this embodiment, the first control component includes a first float valve, the valve of the first float valve is disposed on the water inlet pipe, and the float of the first float valve is located in the second cavity and connected to the valve of the first float valve through a connecting rod.

[0010] In this embodiment, the second control component includes a second float valve, the valve of the second float valve is disposed on the connecting pipe, and the float of the second float valve is located in the second cavity and connected to the valve of the second float valve through a connecting rod.

[0012] In this embodiment, the drain pipe is located at the bottom of the first cavity.

[0013] In this embodiment, the volume of the first cavity is larger than the volume of the second cavity.

[0014] In this embodiment, the bottom of the water tank is a downward-concave arc shape. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The automatic water level control device for water tank 1 according to an embodiment of this application is shown in Figures 1 and 2. The automatic water level control device for water tank 1 includes a water tank 1, an inlet pipe 2, a first control component 3, a connecting pipe 4, and a second control component 5. The water tank 1 includes a first cavity 11 and a second cavity 12 arranged sequentially in a horizontal direction. Water in the first cavity 11 can overflow from its top into the first cavity 11. The inlet pipe 2 is disposed at the top of the water tank 1, and the outlet of the inlet pipe 2 is located above the first cavity 11. The first control component 3 is used to control the inlet pipe 2 to stop injecting liquid into the first cavity 11 when the liquid level in the second cavity 12 is higher than a first preset height, and to control the inlet pipe 2 to stop injecting liquid into the first cavity 11 when the liquid level in the second cavity 12 is lower than a first preset height. At the second preset height, the inlet pipe 2 is opened to allow liquid to enter the first cavity 11. The second preset height is lower than the first preset height. The connecting pipe 4 extends horizontally, with one end connected to the first cavity 11 and the other end connected to the second cavity 12. The second control element 5 is used to control the connecting pipe 4 to connect the first cavity 11 and the second cavity 12 when the liquid level in the first cavity 11 is lower than the third preset height, and to control the connecting pipe 4 to disconnect the connection between the first cavity 11 and the second cavity 12 when the liquid level in the first cavity 11 is higher than the fourth preset height. The fourth preset height is higher than the third preset height and lower than the second preset height.

[0021] It should be noted that when filling the tank 13 with water, the inlet pipe 2 is opened, allowing water to be poured into the first chamber 11. Once the first chamber 11 is full, water continues to be poured into it through the inlet pipe 2. Water in the first chamber 11 can overflow into the second chamber 12. When the overflow water level in the second chamber 12 is higher than the first preset height, the first control unit 3 controls the inlet pipe 2 to stop pouring water into the first chamber 11. When draining water from the first chamber 11, when the water level in the first chamber 11 is lower than the third preset height, the second control unit 5 controls the connecting pipe 4 to connect the first chamber 11 and the second chamber 12. Because the water level in the second chamber 12... When the liquid level is higher than that in the first chamber 11, water in the second chamber 12 can flow into the first chamber 11 through the connecting pipe 4. When the liquid level in the second chamber 12 is lower than the second preset height, the first control unit 3 controls the water inlet pipe 2 to open and inject liquid into the first chamber 11. This achieves control over the water level in the water tank 1, eliminating the need to frequently start the water inlet pipe 2 to inject water into the water tank 1, which helps to improve service life. It also allows for timely replenishment of water by the water inlet pipe 2 when the water level in the water tank 1 is low. Furthermore, the replenishment of water to the second chamber 12 is achieved through the overflow of the first chamber 11, so the liquid level in the second chamber 12 is less affected by the impact of water flow, which helps to improve the accuracy of liquid level control.

[0022] In this embodiment, as shown in FIG1, the water tank 1 includes a tank body 13 and a partition 14 vertically disposed inside the tank body 13. The partition 14 divides the tank body 13 into a first cavity 11 and a second cavity 12. The top height of the partition 14 is lower than the side wall height of the tank body 13.

[0023] Specifically, the partition 14 is sealed to the inner wall of the housing 13. For example, the partition 14 can be connected to the inner wall of the housing 13 by welding. Of course, the partition 14 can also be connected to the inner wall of the housing 13 in other ways, which are not limited here.

[0024] It is understandable that the tank 13 is divided into a first cavity 11 and a second cavity 12 by the vertically arranged partition 14. The division method is simple, and the top height of the partition 14 is lower than the side wall height of the tank 13, which facilitates the overflow of water in the first cavity 11 into the second cavity 12. Furthermore, the liquid level of the water tank 1 can be adjusted by adjusting the height of the partition 14.

[0025] In this embodiment, as shown in FIG1, the connecting pipe 4 is located at the lower part of the partition 14.

[0026] Specifically, the location of the connecting pipe 4 can be adjusted according to actual needs, so its specific location is not limited here.

[0027] By placing the connecting pipe 4 at the lower part of the partition 14, most of the water in the first cavity 11 can flow out before the water is replenished to the first cavity 11 through the second cavity 12, which helps to reduce the number of times the liquid needs to be replenished.

[0028] In this embodiment, as shown in FIG1, the water tank 1 also includes a cover plate 15, which is detachably disposed on the top of the tank body 13.

[0029] The cover plate 15 can be connected to the housing 13 by means of threaded connection or snap-fit. The installation method of the cover plate 15 can be selected according to the actual situation and is not restricted here.

[0030] By setting a cover plate 15 to isolate the inside of the water tank 1 from the outside, the influence of the external environment on the fluctuation of the liquid level inside the water tank 1 is reduced.

[0031] In this embodiment, the volume of the first cavity 11 is larger than the volume of the second cavity 12.

[0032] It is understandable that by setting the volume of the first cavity 11 to be larger than that of the second cavity 12, it is beneficial to increase the water storage capacity in the first cavity 11 and reduce the number of times liquid needs to be added to the water tank 1.

[0033] In this embodiment, as shown in FIG1, the first control component 3 includes a first float valve. The valve of the first float valve is disposed on the water inlet pipe 2, and the float of the first float valve is located in the second cavity 12 and connected to the valve of the first float valve through a connecting rod.

[0034] It should be noted that the float of the first float valve floats on the water. When the water level rises, the float of the first float valve also rises. The rising of the float of the first float valve causes the connecting rod of the first float valve to rise as well. The connecting rod of the first float valve is connected to the valve of the first float valve. When it rises to the first preset height, the connecting rod of the first float valve closes the valve, and water supply to the inlet pipe 2 stops. When the water level drops, the float of the first float valve also drops. When it drops to the second preset height, the connecting rod of the first float valve can open the valve again, thereby replenishing the water tank 1 through the inlet pipe 2.

[0035] In this embodiment, as shown in FIG1, the second control component 5 includes a second float valve. The valve of the second float valve is disposed on the connecting pipe 4, and the float of the second float valve is located in the second cavity 12 and connected to the valve of the second float valve through a connecting rod.

[0036] It should be noted that the float of the second float valve floats on the water. When the water level rises, the float of the second float valve also rises. The rising of the float of the second float valve causes the connecting rod of the second float valve to rise as well. The connecting rod of the second float valve is connected to the valve of the second float valve. When it rises to the fourth preset height, the connecting rod of the second float valve closes the valve of the second float valve, and the connecting pipe 4 is disconnected, that is, the first chamber 11 and the second chamber 12 are not connected. When the water level drops, the float of the second float valve also drops. When it drops to the third preset height, the connecting rod of the second float valve can open the valve of the second float valve again, allowing water in the second chamber 12 to enter the first chamber 11 through the connecting pipe 4.

[0037] In this embodiment, as shown in FIG1, the automatic level control device for water tank 1 further includes a drain pipe 6, which is disposed in water tank 1 and communicates with the first cavity 11.

[0038] Specifically, a drain valve 7 is installed on the drain pipe 6, which controls the opening and closing of the drain pipe 6, thereby facilitating the control of whether to drain the water in the water tank 1 as needed.

[0039] Understandably, the drain pipe 6 facilitates the drainage of water from the water tank 1.

[0040] In this embodiment, the drain pipe 6 is disposed at the bottom of the first cavity 11.

[0041] It is understandable that the drain pipe 6 is placed at the bottom of the first cavity 11 to facilitate the drainage of water from the bottom of the first cavity 11, avoid dead corners where water cannot be drained, and facilitate timely replacement of water in the water tank 1.

[0042] In this embodiment, the bottom of the water tank 1 is a downwardly concave arc shape.

[0043] It is understandable that by setting the bottom of the water tank 1 to a downward-concave arc shape, it is beneficial to allow impurities deposited at the bottom of the water tank 1 to collect and be discharged through the drain pipe 6.
