Description

Technical Field

[0001] This utility model relates to the technical field of water tank protection, and in particular to a water tank anti-buoyancy device. Background Technology

[0002] The water tank is used in sedimentation tanks in sewage treatment to guide the treated water into the intake channel. However, during operation, as the water level in the tank rises, a level difference will form in the water tank fixed to the side wall of the tank. This will cause the water tank to be squeezed and deformed by buoyancy or to displace and fall off, affecting the treatment process. Utility Model Content

[0006] The anti-buoyancy component includes a cylindrical body extending vertically through a fixed bottom plate of the water tank. A water-passing plate is fixed to the upper end of the inner wall of the cylinder, and a screw rod passes through the center of the water-passing plate. A baffle plate is provided at the top of the screw rod, and a compression spring is fixed to the bottom of the water-passing plate. The compression spring is sleeved on the screw rod, and a connecting plate is fixed to the bottom of the screw rod. The screw rod passes through the connecting plate and is fixed by a nut. Several arc-shaped water-passing holes are evenly distributed around the circumference of the water-passing plate. An adjusting plate is rotatably installed on the screw rod. The adjusting plate is located inside the cylinder and fits against the water-passing plate. Several arc-shaped adjusting holes are provided on the adjusting plate, and the arc-shaped adjusting holes are corresponding to the arc-shaped water-passing holes.

[0007] Each arc-shaped adjustment hole on the adjustment plate is provided with a countersunk hole, and each arc-shaped water passage hole on the adjustment hole is provided with a maximum flow pin hole and a minimum flow pin hole. Locking pins are inserted into the countersunk holes and the corresponding maximum or minimum flow pin holes.

[0008] The upper circumference of the outer wall of the cylinder is provided with several vertical limiting grooves, and the bottom circumference of the baffle plate is provided with several limiting rods, which are movably inserted into the corresponding vertical limiting grooves.

[0009] The beneficial effects of this utility model are: the anti-buoyancy component is set on the bottom plate of the water tank of this utility model, so that the water outside the water tank flows into the tank body through the anti-buoyancy component to reduce the liquid level difference, thereby preventing the water tank from being subjected to excessive buoyancy, and preventing the formation of water columns due to the rapid change of liquid level difference, thus preventing the water tank from being deformed or loosened due to excessive buoyancy.

When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] A water tank anti-buoyancy device, such as Figure 1 As shown, it includes a water tank 1 and an anti-buoyancy component 2 installed on the bottom plate of the water tank 1.

[0023] Anti-buoyancy component 2, such as Figures 2-5 As shown, the system includes a cylindrical body 21 that extends vertically through the bottom plate of a fixed water tank 1. A water-passing plate 22 is fixed to the upper end of the inner wall of the cylindrical body 21. A screw 23 passes through the center of the water-passing plate 22. A baffle plate 24 is provided at the top of the screw 23. A compression spring 25 is fixed to the bottom of the water-passing plate 22. The compression spring 25 is sleeved on the screw 23 and a connecting plate 26 is fixed to its bottom. The screw 23 passes through the connecting plate 26 and is fixed by a nut 27. Several arc-shaped water-passing holes 28 are evenly distributed around the circumference of the water-passing plate 22. An adjusting plate 29 is rotatably installed on the screw 23. The adjusting plate 29 is located inside the cylindrical body 21 and fits against the water-passing plate 22. Several arc-shaped adjusting holes 210 are provided on the adjusting plate 29. The arc-shaped adjusting holes 210 are correspondingly arranged with the arc-shaped water-passing holes 28.

[0024] The bottom plate of the water tank 1 of this utility model is provided with an anti-buoyancy component 2, which allows water outside the water tank 1 to flow into the tank body through the anti-buoyancy component 2 to reduce the liquid level difference, so that the water tank 1 will not be subjected to excessive buoyancy, and water columns will not be formed due to the rapid change of liquid level difference, thus preventing the water tank 1 from being deformed or loosened due to excessive buoyancy.

[0025] When the baffle plate 24 is buoyed, it will rise. At this time, external water will pass through the arc-shaped water passage hole 28 of the water passage plate 22 to reduce the liquid level difference. The water flow rate can be adjusted as needed by simply rotating the position of the adjustment plate 29.

A locking pin 214 is inserted into the countersunk hole 211 and the corresponding maximum flow pin hole 212 or minimum flow pin hole 213.

[0027] After the rotating adjustment plate 29 is in place, it can be locked by the locking pin 214 to make it more stable at the maximum or minimum flow rate.

[0028] The upper circumference of the outer wall of the cylinder 21 is provided with several vertical limiting grooves 215, and the bottom circumference of the baffle plate 24 is provided with several limiting rods 216, which are movably inserted into the corresponding vertical limiting grooves 215.

[0029] The vertical limiting groove 215 and the limiting rod 216 ensure that the water baffle 24 moves more stably in the vertical direction.

[0030] The top of the screw 23 is provided with a connecting plate, and the connecting plate is fixedly connected to the bottom of the baffle plate 24 by bolts.

[0031] There are three arc-shaped adjustment holes 210.

[0032] There are three vertical limiting grooves 215 and three limiting rods 216.
