Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a valve structure and a water treatment device having the same. Background Art

[0002] When a suburban highway passes through a water source protection area, in order to prevent polluted rainwater and toxic chemicals in the event of an accident from entering the water source protection area, it is necessary to set up emergency treatment pools on both sides of the highway, and a valve is provided between the emergency treatment pool and the flushing pool to control the water in the flushing pool to automatically flow into the emergency treatment pool. Most of the current valves are opened manually, and it is necessary to observe in real time that the pollutants in the emergency treatment pool are pumped out, and then go to the flushing pool to manually open it, flush the emergency pool, and after the water in the emergency pool is pumped out again, it is necessary to return to the flushing pool to close the valve again. This operation process is relatively cumbersome, and once the valve is forgotten to be closed, when the pollutants enter the emergency pool, they will also enter the flushing pool, causing pollution to the flushing pool. In addition, when the land is tight and the emergency treatment pool needs to be buried under the highway, the emergency pool becomes a closed structure, which makes the above operation inconvenient and easily brings safety hazards. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the valve in the water treatment device in the prior art is inconvenient to open and close, thereby providing a valve structure that can be opened and closed automatically and a water treatment device having the same.

[0004] In order to solve the above technical problems, the present invention provides a valve structure, comprising:

[0005] A valve body is provided at the communication port between the first reservoir and the second reservoir;

[0006] A buoyancy assembly is provided in the first storage container, comprising a connecting member and a buoyancy member connected to the connecting member, wherein the buoyancy member reciprocates up and down along the connecting member under the action of buoyancy;

[0007] A connecting rod assembly is connected to the valve body and has a first position in which the connecting rod is connected to the buoyancy member when the buoyancy member is at a highest floating point, and is disconnected from the buoyancy member when the buoyancy member contacts the bottom wall of the first reservoir to apply a closing force to the valve body, and a second position in which the connecting rod is disconnected from the buoyancy member when the buoyancy member moves from the highest floating point to the bottom wall of the first reservoir to open the valve body.

[0008] Optionally, the connecting member is a bracket provided with a guide rail, the buoyancy member includes a float and a connecting rod, and the float is slidably connected to the guide rail via the connecting rod.

[0009] Optionally, the connecting rod assembly includes a first rod body pivotally connected to the first reservoir and a second rod body overlapped with the connecting rod, and the first rod body and the second rod body are fixedly connected.

[0010] Optionally, a first limiting portion is provided at one end of the second rod body overlapping the connecting rod, and a second limiting portion is provided at one end of the second rod body close to the first rod body. The first limiting portion is clamped with the connecting rod when the buoyancy member is at the highest floating point, and the second limiting portion is clamped with the connecting rod when the connecting rod assembly is in the second position.

[0011] Optionally, the second rod body includes a vertical rod and a horizontal rod vertically connected to each other, the first limiting portion and the second limiting portion are "L"-shaped components formed at the ends of the vertical rod and the horizontal rod respectively, and the opening directions of the two "L"-shaped components are opposite.

[0012] Optionally, an elastic member is further provided at one end of the first rod body pivotally connected to the first reservoir, and the elastic member stores energy when the buoyancy member moves from the highest floating point to the bottom wall of the first reservoir, and releases energy when the buoyancy member reaches and contacts the bottom wall of the first reservoir, thereby closing the valve body.

[0013] Optionally, a bending portion is provided at one end of the first rod body pivotally connected to the first reservoir, and the bending portion is pivotally connected to a protrusion provided on the inner wall of the first reservoir.

[0014] Optionally, a receiving space is formed between the bent portion and an inner wall of the first reservoir, and the elastic member is disposed in the receiving space.

[0015] A water treatment device is also provided, comprising a first storage tank and a second storage tank which are interconnected and arranged, and also comprising the valve structure of the present invention.

[0016] Optionally, the first reservoir is an emergency tank, and the second reservoir is a flushing tank.

[0017] The technical solution of the present invention has the following advantages:

[0018] 1. The valve structure provided by the present invention is that when water or other liquids are stored in the first reservoir and the second reservoir, the buoyancy member is at the highest floating point and is connected to the connecting rod assembly, and the connecting rod assembly applies a closing force to the valve body to close the connecting port between the first reservoir and the second reservoir; when the water or other liquids in the first reservoir are gradually extracted, the buoyancy of the buoyancy member is correspondingly reduced and moves toward the bottom wall of the first reservoir. At this time, the buoyancy member is disconnected from the connecting rod assembly, the valve body is opened, and the water in the second reservoir enters the first reservoir for flushing; when the water in the first reservoir is extracted again, the buoyancy of the buoyancy member disappears and moves to contact with the bottom wall of the first reservoir. At this time, there is no water in the second reservoir and the valve body always remains closed, thereby realizing automatic opening and closing of the valve, which is easy to operate.

[0019] 2. The valve structure provided by the present invention and the arrangement of the second limiting portion on the second rod body ensure that the valve body always remains in an open state during the process of water in the second reservoir entering the first reservoir, thereby preventing the valve body from suddenly closing under the action of water pressure when the water enters the first reservoir but has not yet reached the predetermined position, thereby affecting the flushing effect.

[0020] 3. In the valve structure provided by the present invention, the setting of the elastic member at one end of the first rod body pivotally connected to the first reservoir ensures that when the water in the first reservoir is pumped out again, the connecting rod assembly can be restored to the position of closing the valve body under the action of the elastic member.

[0021] 4. In the water treatment device provided by the present invention, the valve structure is arranged at the connecting port between the emergency pool and the flushing pool, and automatically opens and closes with the change of the water level in the emergency pool, thereby reducing manpower and lowering safety hazards.

[0030] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figures 1 to 5 A specific embodiment of the valve structure shown includes a valve body 4 arranged at a communication port 3 between a first reservoir 1 and a second reservoir 2 , and a buoyancy assembly and a connecting rod assembly arranged in the first reservoir 1 .

[0033] The first storage tank 1 is an emergency tank, and the second storage tank 2 is a flushing tank. The tops of the emergency tank and the flushing tank are both open. Contaminated water is temporarily stored in the emergency tank, and clean water is stored in the flushing tank. The emergency tank and the flushing tank are connected through a pre-buried pipe at the bottom. The valve body 4 is arranged at the opening of the pre-buried pipe near the emergency tank, and in order to ensure the sealing performance, a sealing strip 5 is provided at the connection between the valve body 4 and the pre-buried pipe.

[0034] The buoyancy assembly includes a connector 6 and a buoyancy member connected to the connector 6. The connector 6 is a bracket provided with a guide rail 7, which is arranged on the bottom wall of the emergency pool, and includes a bottom plate fixed to the bottom wall and a U-shaped member arranged on the bottom plate, the opening of the U-shaped member is fixed to the bottom plate, and the middle cavity forms the guide rail 7. The buoyancy member includes a float 8 and a connecting rod 9, the float 8 is a hollow cylindrical float 8, and the cylindrical float 8 is provided with a connecting rod 9 passing through the axis, the connecting rod 9 extends to the outside of the cylindrical float 8, and is horizontally inserted into the guide rail 7, so as to realize up and down reciprocating motion along the guide rail 7 under the action of buoyancy.

[0035] The connecting rod assembly is connected to the valve body 4, and has a first position in which the connecting rod assembly is connected to the buoyancy member when the buoyancy member is at the highest floating point, and is disconnected from the buoyancy member when the buoyancy member contacts the bottom wall of the first reservoir 1 to apply a closing force to the valve body 4, and a second position in which the connecting rod assembly is disconnected from the buoyancy member when the buoyancy member moves from the highest floating point to the bottom wall of the first reservoir 1 to open the valve body 4.

[0036] Specifically, the connecting rod assembly includes a first rod body 10 pivotally connected to the first reservoir 1 and a second rod body 11 overlapped with the connecting rod 9, and the first rod body 10 and the second rod body 11 are fixedly connected vertically to each other. An L-shaped bending portion 12 is provided at one end of the first rod body 10 pivotally connected to the first reservoir 1, and the bending portion 12 is pivotally connected to a protrusion 13 provided on the inner wall of the first reservoir 1. A rotating shaft is provided on the protrusion 13, and the rotating shaft passes through the vertical part of the bending portion 12 to realize the rotation connection between the first rod body 10 and the protrusion 13. An accommodating space is formed between the bending portion 12 and the inner wall of the first reservoir 1, and the protrusion 13 is provided in the accommodating space, and a spring as an elastic member 14 is provided at an upper position in the accommodating space. The elastic member 14 stores energy when the buoyancy member moves from the highest floating point to the bottom wall of the first reservoir 1, and releases energy when the buoyancy member reaches the contact with the bottom wall of the first reservoir 1, driving the connecting rod assembly to move toward the connecting port 3, so that the valve body 4 is closed.

[0037] The second rod body 11 includes a vertical rod and a horizontal rod vertically connected to each other. The end of the vertical rod overlapping the connecting rod 9 is provided with a first limiting portion 15, and the end of the horizontal rod close to the first rod body 10 is provided with a second limiting portion 16. The first limiting portion 15 and the second limiting portion 16 are respectively formed at the ends of the vertical rod and the horizontal rod, and the opening directions of the two "L"-shaped components are opposite. Figure 2 As shown in FIG. 1 , the opening of the "L"-shaped member of the vertical rod faces left, and the opening of the "L"-shaped member of the horizontal rod faces right. When the buoyancy member is at the highest floating point, the first limiting portion 15 is clamped with the connecting rod 9, as shown in FIG. Figure 2 As shown, when the connecting rod assembly is in the second position, the second limiting portion 16 is locked with the connecting rod 9. Figure 4 shown.

[0038] A water treatment device comprises a first storage tank 1 and a second storage tank 2 which are connected to each other, and also comprises the valve structure. The first storage tank 1 is an emergency tank, and the second storage tank 2 is a flushing tank.

[0039] like Figure 1 and 2As shown, when the emergency pool and the flushing pool store contaminated water and clean water respectively, the float 8 is at the highest floating point, that is, under the action of buoyancy, the float 8 moves to the top sealing part of the U-shaped part driven by the connecting rod 9. At this time, the first limiting portion 15 of the second rod body 11 is overlapped on the connecting rod 9. Even if the water level in the flushing pool is higher than the water level in the emergency pool, due to the obstruction of the connecting rod 9, the water pressure in the flushing pool is not enough to open the valve body 4.

[0040] like Figure 3 As shown, when the contaminated water in the emergency pool is gradually extracted, the buoyancy of the float 8 is reduced accordingly, and the float 8 moves toward the bottom wall of the emergency pool along the guide rail 7 in the middle of the U-shaped member under the drive of the connecting rod 9. At this time, the first limit portion 15 of the second rod body 11 is disconnected from the connecting rod 9. Under the water pressure of the flushing pool, the valve body 4 opens, driving the first rod body 10 to move toward the left side, and compressing the spring to store energy, and the water in the flushing pool enters the emergency pool through the connecting port 3 for flushing; Figure 4 As shown, when the amount of water entering the emergency pool reaches a certain amount, the float 8 floats up under the action of buoyancy, and the second limiting portion 16 of the second rod body 11 is connected to the connecting rod 9. At this time, due to the obstruction of the second limiting portion 16, the movement of the connecting rod assembly to the right is restricted. At the same time, the valve body 4 is subjected to the impact force of the water in the right flushing pool, so the valve body 4 always remains in an open state.

[0041] like Figure 5 As shown, when the water in the emergency pool is pumped out again, water is no longer released from the flushing pool, the buoyancy of the float 8 disappears, and the float moves until it contacts the bottom wall of the emergency pool. The connection between the second rod body 11 and the connecting rod 9 is disconnected, and at the same time, the connecting rod assembly moves toward the connecting port under the elastic force of the spring, and the valve body 4 is closed.

[0042] When contaminated water appears in the emergency pool again, the buoy 8 floats up, and the first limiting portion 15 of the second rod body 11 is connected to the connecting rod 9 for limiting again. Even if the water level in the flushing pool is higher than the emergency pool, the valve body 4 always remains closed until water is pumped out of the emergency pool again.

[0043] As an alternative embodiment, the connecting member 6 may also be a rope, one end of which is fixed to the bottom wall of the emergency pool, and the other end of which is fixed to the connecting rod 9 of the buoy 8 .

[0044] As an alternative embodiment, the connecting rod assembly includes a first oblique rod and a second oblique rod arranged at an angle, the two ends of the first oblique rod are respectively connected to the inner wall of the emergency pool and the connecting rod 9 of the buoy 8, one end of the second oblique rod is connected to the valve body 4, and a third limiting portion is provided near the other end which is limitedly connected to the connecting rod 9 of the buoy 8.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
