Abstract

A fully enclosed digital hydraulic flow and direction control gate includes: a frame, a valve plate, a rotating shaft, a sealing assembly, a sealing power assembly, and an online flow monitoring assembly. Multiple valve plates are installed in the frame through the rotating shaft, and adjacent valve plates rotate synchronously in opposite directions to achieve flow and direction control. The sealing assembly is pushed by the sealing power assembly to achieve sealing and disengagement with the upper and lower surfaces of the valve plates, thereby achieving a fully enclosed seal. As the optimal sealing solution, the lower pressure ring and the lifting ring are directly and symmetrically sleeved on both ends of the rotating shaft. The rotating shaft drives the valve plate to rotate to synchronously achieve the lifting and lowering of the sealing assembly. It has low cost, less subsequent maintenance, and mechanical transmission to ensure the stability of dynamic sealing. It meets the needs of equal water flow in multiple water supply channels while forming turbulent flow to flush sediments in the treatment pool and complete self-cleaning. The valve plate opening angle is regulated online in real time to optimize the inflow energy and angle of the sewage pool, form a large space with uniformly distributed streamlines, and eliminate vortices and short flows.

Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a fully enclosed digital hydraulic flow and direction regulating gate. Background Art

[0002] In order to ensure that the water levels in the distribution channels drop simultaneously during the sewage treatment process and that they do not break, twist or deform due to water pressure, the Shanghai Municipal Engineering Design and Research Institute applied for a "flow and direction adjustment gate" on June 3, 2010. This allows for the simultaneous release of water from multiple distribution channels, and the turbulence generated by the interaction of water flows in different directions during the release process can effectively flush the bottom of the sewage treatment pool, avoid the accumulation of impurities and dead corners, and complete a single thorough cleaning of the water treatment pool.

[0003] The flow and direction regulating gate breaks through the use environment limitations of traditional circular regulating valves, meets the water flow regulation requirements of large rectangular treatment tanks, and provides a basic guarantee for the efficient operation of municipal sewage treatment and industrial wastewater treatment fields; however, in actual use, the staff encountered a greater problem: due to the large water treatment capacity and the large depth of the water treatment tank, the existing sealing structure of the flow and direction regulating gate is unable to withstand the leakage caused by low-level water pressure. Sewage leakage greatly weakens the advantage of the flow and direction regulating gate in synchronously regulating multiple water flows, making the precise control of water flow in multiple water distribution channels a pipe dream.

[0004] In order to ensure the normal use of the flow and direction diversion gate, a complete set of monitoring systems, local adjustment systems, automatic sensing systems, etc. have to be added on the basis of the original treatment system. The initial construction costs, mid-term manual control costs, and later maintenance costs are huge. At the same time, the above systems will inevitably occupy the effective space of the sewage treatment pool, reducing the single processing capacity of the sewage treatment pool.

[0005] The present invention proposes a fully enclosed digital hydraulic flow and direction regulating gate, which solves the problem of the airtightness of the flow and direction regulating gate and fundamentally solves the problem. Summary of the Invention

During the movement of the second strip teeth, the upper or lower parallel section of the wire ring is pulled to move unidirectionally. At this time, the sealing gasket support plates fixed to both sides of the wire ring move synchronously, that is, move toward and away from the valve plate at the same time, completing the sealing and separation operation between the sealing assembly and the upper and lower plate surfaces of the valve plate.)

The following specific embodiments will further illustrate the present invention in combination with the above-mentioned drawings. DETAILED DESCRIPTION

[0034] Specific implementation case 1:

[0035] A fully enclosed digital hydraulic flow and direction control gate comprises: a frame 1, a valve plate 2, a rotating shaft 3, a sealing assembly, and a sealing power assembly. Two valve plates 2 are mounted on the inner side of the frame 1 via the rotating shaft 3. The rotating shaft 3 passes through the frame 1 and is rotatably connected to the frame 1. The upper and lower surfaces and side surfaces of the valve plates 2 are all provided with the sealing assemblies. Part or all of the sealing assemblies achieve stable sealing under the action of the sealing power assembly. The side surfaces between two adjacent valve plates 2 are squeeze-sealed by sealing strips. The sealing power assembly acts on the sealing assemblies above and below the valve plates 2, causing the sealing assemblies to form a dynamic, stable seal with the upper and lower surfaces of the valve plates 2.

[0036] Among them, the two adjacent valve plates 2 rotate in opposite directions (rotating in the form of double doors to achieve flow and direction adjustment), and the valve plates 2 of the flow and direction adjustment gate are controlled to rotate by a driving component, and a gear is provided at the end of the rotating shaft 3 corresponding to each valve plate 2; when N is equal to 2, the driving component includes a driving motor, a first bar tooth 51, and a redirecting wheel 52, and the redirecting wheel 52 is engaged with the gear at the end of one of the rotating shafts 3, and the gear at the end of the other rotating shaft is connected to the power output shaft of the driving motor, and the gears at the ends of the rotating shaft 3 are all engaged with the first bar tooth 51.

[0037] The two valve plates share a first strip tooth 51. Through the redirection function of the redirecting wheel 52, the first strip tooth 51 drives the two valve plates 2 to rotate synchronously in opposite directions. Figure 1 shown.

[0038] Specific implementation case 2:

[0039] A fully enclosed digital hydraulic flow and direction control gate comprises: a frame 1, a valve plate 2, a rotating shaft 3, a sealing assembly, and a sealing power assembly. Four valve plates 2 are mounted on the inner side of the frame 1 via the rotating shaft 3. The rotating shaft 3 passes through the frame 1 and is rotatably connected to the frame 1. The upper and lower surfaces and side surfaces of the valve plates 2 are all provided with the sealing assemblies. Part or all of the sealing assemblies achieve stable sealing under the action of the sealing power assembly. The side surfaces between two adjacent valve plates 2 are squeeze-sealed by sealing strips. The sealing power assembly acts on the sealing assemblies above and below the valve plates 2, causing the sealing assemblies to form a dynamic, stable seal with the upper and lower surfaces of the valve plates 2.

[0040] Among them, the two adjacent valve plates 2 rotate in opposite directions (rotating in the form of double-doors to achieve flow and direction adjustment), and a gear is provided at the end of the rotating shaft 3 corresponding to each valve plate 2. The valve plate 2 of the flow and direction regulating gate is controlled to rotate by a driving component, and the driving component includes a driving motor, two first bar teeth 51, and a redirecting wheel 52. The first of the first bar teeth 51 is engaged with the gear at the end of the even-numbered rotating shaft 3, and the second of the first bar teeth 51 is engaged with the gear at the end of the odd-numbered rotating shaft 3. The gear engaged with the first of the first bar teeth 51 is connected to the power output shaft of the driving motor and the redirecting wheel 52 is directly or indirectly engaged with the gear, and the redirecting wheel 52 is engaged with the second of the first bar teeth 51.

[0041] The two first strip teeth 51 are used to drive the valve plates 2 with the same rotation direction to rotate synchronously and in the same direction. The four valve plates share a driving motor to achieve synchronous reverse rotation of the valve plates 2, which can achieve equal water flow discharge in the water distribution channel without setting up complex internal control circuits, such as Figure 2 shown.

[0042] Specific implementation case 1 and specific implementation case 2 respectively demonstrate drive components for controlling the rotation of different numbers of lower valve plates 2 , and the same drive component is always used to drive the synchronous rotation of all valve plates 2 .

[0043] The sealing component is defined below as a sealing gasket made of rubber material to further illustrate the key innovative technical solution of the present invention - that is, the stable sealing of the upper and lower surfaces of the valve plate 2. During actual use, the specific structure and material of the sealing component can be changed as needed. This is not a limitation of the sealing component.

[0044] Specific implementation case 3:

[0045] In a fully enclosed digital hydraulic flow and direction regulating gate, the sealing power component is a wire ring component (such as Figure 3As shown), the wire ring assembly includes a wire ring 71, a fixed pulley 72, a second strip tooth 73, and a transmission tooth assembly 74. Fixed pulleys are provided at the four corners of the wire ring 71. The upper or lower parallel length section of the wire ring 71 is directly or indirectly connected to the second strip tooth 73, and the transmission tooth assembly 74 is meshed with the transmission tooth assembly. The transmission tooth assembly includes a first transmission tooth 74 that directly meshes with the second strip tooth 73. The first transmission tooth 74 can be controlled by a separate motor, or an intermediate transmission tooth can be added to the transmission tooth assembly 74. The drive assembly is shared with the valve plate 2 through one or more intermediate transmission teeth. Different sides of the wire ring 71 are fixed to the sealing gasket support plate 45 located above and below the valve plate 2 by L-shaped rods, wherein each valve plate corresponds to a wire ring 71 and four fixed pulleys 72. The second strip tooth 73 and the transmission tooth assembly 74 can be shared by multiple valve plates or designed separately.

[0046] Optionally, the intermediate transmission tooth is sleeved on the end of one of the rotating shafts 3 and is directly engaged, indirectly engaged or chain-driven with the first transmission tooth 74, thereby driving the movement of the second bar tooth 73. During the movement of the second bar tooth 73, the upper or lower parallel section of the wire ring 71 will be pulled to move unidirectionally. At this time, the sealing pad support plate 45 fixed to both sides of the wire ring 71 moves synchronously, that is, it moves toward and away from the valve plate 2 at the same time, completing the sealing separation operation of the sealing assembly and the upper and lower plate surfaces of the valve plate 2.

[0047] The above is the initial solution developed by the inventors after extensive research. However, given the operational characteristics and operating environment of the flow and directional control gate, which is a one-time installation component for permanent use, the wire rope assembly has limited load capacity. Wire wear needs to be monitored regularly and service life estimated, with replacement and repair necessary. After careful consideration, the inventors concluded that while the above solution provides a relatively stable seal for the upper and lower panels of valve 2, it is unsuitable for long-term operation. To address this issue, the inventors continued their research and experiments, ultimately arriving at the technical solution for Specific Implementation Plan 4.

[0048] Specific implementation case 4:

[0049] In a fully enclosed digital hydraulic flow and direction regulating gate, the sealing power component is an eccentric wheel component (such as Figure 4As shown), the eccentric wheel assembly includes two groups of eccentric shafts 61 and eccentric wheels 62, which are respectively located above the upper sealing gasket support plate 45 and below the lower sealing gasket support plate 45, and the two eccentric wheels 62 are sleeved and installed on the eccentric shaft 61. The eccentric wheel 62 is processed with a hanging groove 63 on the side away from the eccentric point, and the sealing gasket support plate 45 is connected by a hanging ring passing through the hanging groove 63; during the sealing process, the hanging groove 63 rotates toward the direction close to the sealing gasket support plate 45, and the eccentric wheel 62 pushes the sealing gasket support plate 45 to move close to the valve plate 2 until the sealing gasket on the plate surface of the sealing gasket support plate 45 is close to the plate surface of the valve plate 2 to form a stable sealing structure; during the water release process, the hanging groove 63 rotates toward the direction away from the sealing gasket support plate 45, and under the tension of the hanging ring, the sealing gasket support plate 45 and the sealing gasket are driven away from the valve plate 2, and the two ends of the sealing gasket support plate 45 slide along the lifting track inside the frame 1.

[0050] Optionally, eccentric wheel assemblies are provided on both sides of the valve plate 2, and the sealing gasket support plates 45 provided on both sides of the valve plate 2 can be translated to complete the sealing between the sealing gasket support plates 45 on both sides and the side plate surfaces of the valve plate 2. The eccentric shafts in the eccentric wheel assemblies on both sides can be separately provided with a rotating motor drive, or can be driven by a bevel gear and an additional bevel gear on the rotating shaft 3, so that the sealing power assembly and the valve plate share a driving source, and static sealing can also be achieved on both sides of the valve plate 2 through a sealing strip.

[0051] The eccentric wheel assembly of the above-mentioned specific implementation scheme solves the problem of low service life of the wire ring assembly in specific implementation case 1, avoiding cumbersome subsequent maintenance steps; transmission teeth are set at the end of the eccentric shaft in the eccentric wheel assembly, which is directly driven by a motor or driven by a gear chain or meshing transmission added through intermediate transmission teeth and the rotating shaft of the valve plate. The long-term use effect is good, the practical life is long, and the sealing stability of the upper and lower plates of the valve plate 2 is high. However, the inventor continued to optimize the technical solution of the flow and direction control gate on the basis of the above-mentioned technical solution based on the principle of structural simplicity and optimization design, such as specific implementation scheme 5.

[0052] Specific implementation case 5:

[0053] In a fully enclosed digital hydraulic flow and direction regulating gate, the sealing power assembly includes a lower pressure ring 41 and a lifting ring 42, and the ring walls of the lower pressure ring 41 and the lifting ring 42 are processed with a travel groove 43, the lower pressure ring 41 and the lifting ring 42 are symmetrically sleeved on the upper and lower ends of the rotating shaft 3, and the axial surfaces of the upper and lower ends of the rotating shaft 3 are provided with a transverse shaft 44, and the transverse shaft 44 passes through the travel groove 43 of the lower pressure ring 41 and the lifting ring 42, and the lower plate surface of the lower pressure ring 41 and the upper plate surface of the lifting ring 42 are fixed with a sealing gasket support plate 45, and the plate surface of the sealing gasket support plate 45 is fixed with a sealing gasket, and the sealing gasket is pressed against the rotating shaft 3 through elastic force.

[0054] During the rotation of the rotating shaft 3, the transverse shaft 44 rotates synchronously in the stroke groove 43. The height of the transverse shaft 44 remains unchanged during the rotation. Due to the different heights of the stroke groove 43, when the transverse shaft 44 moves from the transverse groove section of the stroke groove 43 to the inclined groove section, the lower pressure ring 41 moves downward and the lifting ring 42 moves upward, pushing the sealing gasket support plate 45 and the sealing gasket to fit tightly against the upper and lower plate surfaces of the valve plate 2. Figure 5 shown.

[0055] After repeated design, experimentation and verification, the sealing power assembly in this specific implementation case only needs to be sleeved with the lower pressure ring 41 and the lifting ring 42 on the upper and lower ends of the rotating shaft 3 corresponding to the valve plate 2. The valve plate 2 and the upper and lower plate surface sealing assembly can be tightly fitted together through the force between the transverse shaft 44 and the stroke groove 43. No other auxiliary transmission parts are required. It is low in cost, easy to construct and does not require excessive subsequent maintenance. It is suitable for a component that can be installed once and used permanently for a flow and direction regulating gate.

[0056] Other parts in the patent of this invention can adopt common structures such as sealing rings, oil seals, sealing strips in the existing technology to achieve local sealing. The patent of this invention does not go into too much detail on this, but only gives a detailed description of the key structure faced in the current sewage treatment project, namely the sealing of the upper and lower plates of the valve plate 2. However, it does not mean that other parts are not sealed.

[0057] Specific implementation cases 1 to 5 also include an online flow monitoring component, which includes an online flow velocity test probe and an online flow calculation module. The valve flow data is obtained by collecting the water section flow velocity data fed back by the online flow velocity test probe and multiplying it by the water section area. The valve plate opening angle for regulating the flow and direction of the valve is adjusted online according to the water section flow velocity data, so as to optimize the inflow energy and angle of the sewage pool, form a large space uniformly distributed streamline, and eliminate vortices and short flows.

[0058] The valve opening and closing actions and the sealing lifting actions designed in the present invention are driven by the same driving assembly. In actual use, different driving devices can also be used to act separately.

[0059] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.

The drive assembly is shared with the valve plate through one or more intermediate transmission teeth. Different sides of the wire ring are fixed to the sealing gasket support plate surface above and below the valve plate by L-shaped rods respectively; each valve plate corresponds to a wire ring and four fixed pulleys. The second strip tooth and the transmission tooth assembly are shared by all valve plates or M valve plates, where M is less than N.

8. A fully enclosed digital hydraulic flow and direction regulating gate as claimed in claim 1, characterized in that: The flow online monitoring component includes an online flow velocity test probe and an online flow calculation module. The flow data of the valve flow is obtained by collecting the water section flow velocity data fed back by the online flow velocity test probe and multiplying it by the water section area. The valve plate opening angle for flow and direction adjustment is adjusted online based on the water section flow velocity data to eliminate vortexes and short flows.
