Description

Technical Field

[0001] This utility model relates to the field of water collection tank technology, specifically to a water collection tank anti-buoyancy device. Background Technology

[0002] Water collection tanks are common water treatment equipment in waterworks and sewage treatment plants, often used in the effluent section of sedimentation tanks. Traditional water collection tanks frequently encounter problems during use, such as floating or even deformation due to buoyancy. This floating makes it difficult to reinforce the tank, thus increasing its structural strength and consequently raising manufacturing costs.

[0003] The common practices of existing anti-buoyancy technology for water collection tanks are: one is to directly open holes at the bottom or both sides of the tank, which can easily cause excessive water flow through the anti-buoyancy holes, resulting in short-circuiting of the outflow and affecting the quality of the outflowing water; the other is to install a self-weight closed anti-buoyancy device at the bottom of the tank, but the commonly used anti-buoyancy devices have a complex structure, affect the water flow, and are prone to trapping debris.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 This utility model provides a technical solution: a water collection tank anti-buoyancy device, including a water collection tank body 1, with an outlet 1.1 at the bottom of the rear wall of the water collection tank body 1, and overflow toothed plates 1.2 respectively provided on the top of the side walls of the water collection tank body 1. Pairs of shaft holes 1.4 are provided on the top of the side walls of the water collection tank body 1 near the rear end. Multiple bottom holes 1.3 are provided on the bottom plate of the water collection tank body 1 at the position in front of the swing weir gate 6.

[0030] The swing weir gate 6 includes a shaft 6.1 with both ends fitted into shaft holes 1.4, a bushing 6.2 rotatably fitted onto the shaft 6.1, and a weir plate 6.3 with its top end fixed to the bottom of the bushing 6.2. The two side walls of the water collection tank body 1 are provided with shaft holes 1.4 that match the ends of the shaft 6.1. That is, when there is a certain water level at the front of the inner cavity of the water collection tank body 1, the weir plate 6.3 can be pushed back open, allowing water to flow out through the outlet 1.1. In addition, to flexibly adjust the water level height maintained in the water collection tank body 1, the rear wall of the weir plate 6.3 is provided with multiple mounting slots 6.3.1, and counterweights 6.4 can be detachably installed at the mounting slots 6.3.1. That is, by installing a certain number of counterweights 6.4, the external force required to push the weir plate 6.3 open can be achieved, thereby maintaining the water level height inside the water collection tank body 1. The counterweight 6.4 and the mounting groove 6.3.1 can be connected by a threaded connection to facilitate the disassembly, assembly, addition, and removal of the counterweight 6.4.

[0031] The base 2 includes a conical shell 2.1 and an externally threaded tube 2.2 fixedly mated to the top of the conical shell 2.1 and threadedly connected to the bottom hole 1.3.

[0032] The movable vertical shaft 3 is vertically mounted in the central cavity of the base 2. The top and bottom ends of the movable vertical shaft 3 are respectively equipped with threaded joints 3.1.

[0033] The float 4 is fixed to the top of the movable vertical shaft 3. The bottom center of the float 4 is fitted with an internal threaded sleeve 4.1 that matches the threaded connection of the threaded connector 3.1. This facilitates the assembly and disassembly of the float 4 and the movable vertical shaft 3.

[0034] The sealing plug 5 is centrally fitted onto the bottom end of the movable vertical shaft 3, and the sealing plug 5 is fitted and matched with the inner cavity of the conical housing 2.1. Among them, the sealing plug 5 has a threaded hole 5.1 at its center that matches the threaded connection of the threaded joint 3.1.

[0035] In summary, during use, when the water level in the sedimentation tank is low, the sealing plug 5 falls to its lowest position under gravity. At this time, the central cavity of the base 2 connects the inner cavity of the water collection tank body 1 with the external space, meaning the anti-floating hole is in the open state. At this time, the weir plate 6.3 is in an upright state under gravity, separating the front part of the inner cavity of the water collection tank body 1 from the outlet 1.1.

[0036] When the water level in the sedimentation tank is higher than the bottom of the collection tank body 1, the water flows into the front of the inner cavity of the collection tank body 1 through the central cavity (i.e., the anti-floating hole) of the base 2. In the initial stage, the swing weir gate 6 is in the closed state to maintain a certain water level in the collection tank body 1 and prevent the collection tank body 1 from floating.

[0037] As the water level in the pool rises further, water flows from the overflow toothed plate 1.2 or the central cavity of the base 2 into the water collection tank body 1. When the water level in the water collection tank body 1 reaches the set water level, the float 4, under the action of buoyancy, pulls the sealing plug 5 upward through the movable vertical shaft 3 until the sealing plug 5 is fitted into the inner cavity of the conical shell 2.1, thereby achieving automatic closure of the anti-buoyancy hole. At this time, the water level meets the requirement of pushing open the swing weir gate 6, that is, the hydraulic weir gate opens automatically, and the water collection tank body 1 enters the drainage state.

[0038] As the water level in the pool drops, the anti-buoyancy hole automatically reopens. When the water level in the water collection tank 1 drops below the set water level, the swing weir gate 6 closes again to maintain a certain water level in the water collection tank 1 and prevent the water collection tank 1 from floating.
