[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] To address the technical problem that the depth of the overflow hole in the overflow pipe of the liquid storage tank cannot be adjusted in the prior art, this utility model provides a liquid level adjustment mechanism for the liquid storage tank, which can adjust the depth of the overflow hole in the overflow pipe, thereby adjusting the liquid level in the liquid storage tank.

[0026] Please see Figures 1-4 , Figures 1-4 According to one embodiment of the present invention, a liquid level adjustment mechanism for a storage tank includes a tank body 1 and an overflow unit 2. The tank body 1 has a storage chamber 1a and a drain hole 1b, and the drain hole 1b is connected to the storage chamber 1a. The overflow unit 2 includes a guide pipe 21 and an overflow pipe 22. The guide pipe 21 is disposed in the storage chamber 1a and fixedly connected to the tank body 1, and the lower end of the guide pipe 21 corresponds to the drain hole 1b. The lower end of the overflow pipe 22 is threadedly rotatably connected to the upper end of the guide pipe 21, and the side wall of the upper end of the overflow pipe 22 has an overflow port 22a. Rotating the overflow pipe 22 can drive the overflow pipe 22 to move relative to the guide pipe 21, so as to adjust the distance between the overflow port 22a and the bottom wall of the storage chamber 1a.

[0027] In actual use, when the liquid is transported to the storage chamber 1a of the tank 1, if the liquid is an acidic liquid such as dilute sulfuric acid, the operator needs to wear waterproof gloves. Rotating the overflow pipe 22 will drive the overflow pipe 22 to move relative to the guide pipe 21, thereby driving the overflow port 22a at the upper end of the overflow pipe 22 to rise or fall, and adjusting the distance between the overflow port 22a and the bottom wall of the storage chamber 1a. When the liquid level in the storage chamber 1a reaches the position of the overflow port 22a, the liquid exceeding the liquid level can enter the overflow pipe 22 and the guide pipe 21 in sequence through the overflow port 22a and be output through the drain hole 1b, thus keeping the liquid level in the storage chamber 1a constant.

[0028] It is understandable that the inner wall of the upper end of the guide pipe 21 is provided with an internal thread, and the lower end of the overflow pipe 22 is provided with an external thread that matches the internal thread, wherein the length of the external thread section is greater than the length of the internal thread section.

[0029] It should be noted that, in one embodiment, the lower end of the overflow pipe 22 is inserted into the guide pipe 21, and at least one sealing ring 23 is sleeved on the outer wall of the lower end of the overflow pipe 22, and the sealing ring 23 is in contact with the inner wall of the guide pipe 21.

[0030] In one embodiment, three sealing rings 23 are spaced apart on the outer wall of the lower end of the overflow pipe 22. The sealing rings 23 are elastic rubber sealing rings. Specifically, the outer wall of the lower end of the overflow pipe 22 is provided with an annular groove, and the sealing rings 23 are fitted on the annular groove.

[0031] In one embodiment, the length of the guide pipe 21 is 1 / 2 of the depth of the liquid storage chamber 1a, and the length of the overflow pipe 22 is 2 / 3 of the depth of the liquid storage chamber 1a.

[0032] It should be noted that, based on the above scheme, in order to facilitate the operator to drive the overflow pipe 22 to rotate, a drive mechanism 3 is also included. The drive mechanism 3 includes a crossbar 31, which is fixedly connected to the upper end of the overflow pipe 22.

[0033] In one embodiment, two crossbars 31 can be fixed at intervals on the periphery of the upper end of the overflow pipe 22, and the operator can hold the two crossbars 31 with both hands respectively, so as to facilitate driving the overflow pipe 22 to rotate.

[0034] In another embodiment, the crossbar 31 corresponds to the opening at the upper end of the overflow pipe 22 and is arranged in the radial direction of the opening; specifically, the crossbar 31 divides the opening at the upper end of the overflow pipe 22 into two, so that the circular opening becomes two semi-circular openings, and the operator can hold the crossbar 31 to drive the overflow pipe 22 to rotate.

[0035] In one embodiment, the crossbar 31 can be an arc-shaped bar, and the arc-shaped convex surface of the crossbar 31 is located above the overflow pipe 22; this can avoid the situation where the two semi-circular openings are too small, making it difficult for the operator to hold the crossbar 31.

[0036] It should be noted that, in this specific embodiment, the driving mechanism 3 further includes two guide rods 32 and a handle 33. The two guide rods 32 are spaced apart and slidably disposed on the crossbar 31, and the upper ends of the two guide rods 32 are connected to the handle 33. The lower ends of the two guide rods 32 pass through the overflow pipe 22.

[0037] Understandably, when the overflow pipe 22 does not need to be rotated, the handle 33 is in contact with the crossbar 31.

[0038] It should be noted that, based on the above scheme, the handle 33 has an arc-shaped curved section. The operator can hold the part of the arc-shaped curved section and pull the two guide rods 32 upward. The operator can rotate the handle 33 to rotate the overflow pipe 22.

[0039] Based on the above scheme, the lower ends of the two guide rods 32 are provided with protrusions 34, and the protrusions 34 can abut against the crossbar 31; specifically, by providing two protrusions 34 at the lower ends of the two guide rods 32 respectively, it is possible to prevent the two guide rods 32 from slipping off the crossbar 31.

[0040] It should be noted that the guide pipe 21 is an alloy guide pipe, the overflow pipe 22 is an alloy guide pipe, and the pool body 1 is an alloy pool body or a stainless steel pool body.

[0041] It should be noted that, in one embodiment, the bottom of the pool body 1 is provided with an inlet pipe that communicates with the liquid storage chamber 1a, and a control valve is provided on the inlet pipe.

[0042] In addition, in one embodiment, the bottom of the pool body 1 is provided with a drain pipe that communicates with the liquid storage chamber 1a, and the drain pipe is provided with a valve body, so that liquid that cannot be discharged from the liquid storage chamber 1a through the overflow port 22a can be discharged through the drain pipe.

[0043] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
