Abstract
Description
Technical Field
[0001] This application relates to the field of wastewater treatment, and more specifically, to an observation window and a biological tank with an observation window on top. Background Technology
[0002] In the wastewater treatment process, in order to facilitate remote monitoring of water quality and equipment operation in the biological tank by staff, and to ensure the safety and stability of the treatment process, observation windows are usually installed at the top of the biological tank. This helps to check changes in foam, sediment, etc. in the tank in real time, reduces the risk of staff entering the tank, and facilitates equipment maintenance and operation record management, thereby improving overall work efficiency and safety.
[0003] Currently, observation windows on biological treatment tanks are typically laid flat on the top of the tank. While this meets basic observation needs to some extent, it also has several drawbacks. Flat observation windows easily accumulate dust, debris, and stains from splashed wastewater, affecting the clarity of observation. Staff struggle to accurately judge subtle changes in water quality and the precise operational status of equipment through blurry windows. Furthermore, during rainy days or when wastewater levels are high, flat observation windows may completely obstruct the view due to water accumulation, significantly reducing the effectiveness of real-time monitoring. From a safety perspective, flat observation windows lack effective protective measures around them, posing a risk of slipping and falling into the tank when staff approach. In the event of an accident, not only would personnel safety be seriously threatened, but wastewater treatment operations could also be interrupted, leading to a series of environmental problems.
[0004] Therefore, how to provide an observation window that at least partially solves the above problems has become a technical problem that needs to be solved in this field. Utility Model Content
[0005] In view of this, this application proposes an observation window and a biological pool.
[0006] According to one aspect of this application, an observation window is provided, comprising: an observation window body, which is protrudingly and fixedly disposed on the top of a biological pool; and an inspection window disposed on the side of the observation window body for observing the biological pool and taking samples from the biological pool; wherein the angle between the inspection window and the top surface of the biological pool is less than 90°.
[0007] Preferably, the radial cross-section of the observation window is triangular, and the observation window includes: two quadrilateral sides covering the top of the biological pool; and two triangular sides fixedly connected to the quadrilateral sides to form a closed space at the top of the biological pool; wherein the inspection window is disposed on at least one quadrilateral side.
[0008] Preferably, the observation window includes multiple keels disposed on the inner side of the quadrilateral side; and a cover fixedly connected to the keels and the top of the biological pool to form a sealed space for the observation window.
[0009] Preferably, the number of keels is at least 2, and more preferably 4; the keels are triangular, and the two ends of the base of the triangular keel are fixedly overlapped on the top of the side wall of the biological pool and / or the base of the triangular keel is fixedly set on the top of the side wall of the biological pool.
[0010] Preferably, the material of the cover is one of stainless steel, tempered glass, and polycarbonate.
[0011] Preferably, the quadrilateral side openings of the observation window form an inspection window, and the inspection window covers or fits into the inspection window and is movably connected to the observation window.
[0012] Preferably, the inspection window and the observation window are connected by a hinged connection to facilitate switching between the open and closed states of the inspection window.
[0013] Preferably, the observation window is also provided with a locking device for securely closing the inspection window.
[0014] Preferably, the inspection window is made of one of the following materials: plexiglass, tempered glass, polycarbonate, or metal panel.
[0015] According to another aspect of this application, a biological pool is proposed, which includes a pool body and an observation window disposed above the pool body, the observation window being the one described above.
[0016] The observation window proposed in this application provides a wider field of view for observing the biological pool, effectively avoids the problem of water accumulation at the top of the observation window, and facilitates personnel to observe and take samples from the side, effectively avoiding the risk of falling into the biological pool and ensuring personnel safety.
[0017] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description
[0018] The accompanying drawings, which form part of this application, are used to provide a further understanding of this application, and the illustrative embodiments and descriptions thereof are used to explain this application. In the drawings:
[0019] Figure 1 This is a schematic diagram of an observation window according to a preferred embodiment of this application.
[0020] Figure 2 This is a perspective view of the viewing window according to a preferred embodiment of this application.
[0021] Figure 3 This is a schematic diagram of the triangular side view of the viewing window according to a preferred embodiment of this application. Detailed Implementation
[0022] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] Traditional biological treatment tanks typically use flat-laid observation windows, which limits the visible area for staff. Secondly, during sampling and observation, there is a high risk of personnel falling into the tank, causing safety accidents. Furthermore, with flat-laid observation windows, wastewater and debris tend to accumulate at the top, easily entering the tank. Additionally, when the water level in the tank is high, wastewater can easily splash out, obstructing observation.
[0024] Therefore, according to one aspect of this application, an observation window is provided, comprising: an observation window body 1, which is protruding and fixedly disposed on the top of a biological pool; and an inspection window 2, which is disposed on the side of the observation window body 1 for observing the biological pool and taking samples from the biological pool; wherein the angle between the inspection window 2 and the top surface of the biological pool is less than 90°.
[0025] The aforementioned observation window 1 is protruding and fixedly connected to the top of the biological tank. The fixed connection method can be bolt connection. During installation, the observation window 1 can be directly fixed to the top of the biological tank with bolts.
[0026] The size of the observation window 1 is determined according to the size of the biological pool so that it can cover the top of the biological pool.
[0027] The aforementioned inspection window 2 is located on the side of the observation window 1. The bottom of the inspection window 2 is at a certain height relative to the top of the biological tank; the specific height is set according to the actual situation. When the inspection window is opened or closed, the angle formed between it and the biological tank is less than 90°. This reduces the risk of operators accidentally falling into the biological tank during observation or sampling. The angle of less than 90° also helps to avoid the possibility of sewage splashing onto personnel. In addition, it provides operators with a better viewing angle; the tilted inspection window 2 makes it easier to see the situation at different depths and angles within the biological tank, reducing blind spots.
[0028] The observation window 1 can be of a suitable shape to allow the inspection window 2 to be tilted towards the biological pool. According to a preferred embodiment of this application, the radial cross-section of the observation window 1 can be triangular. The observation window 1 may include: two quadrilateral sides covering the top of the biological pool; and two triangular sides fixedly connected to the quadrilateral sides, forming a closed space at the top of the biological pool. The inspection window 2 is disposed on at least one quadrilateral side, preferably two sides. The radial cross-section triangle of the observation window 1 can be an isosceles triangle, an equilateral triangle, or a scalene triangle, preferably an equilateral triangle or an isosceles triangle, more preferably an isosceles triangle. An isosceles triangle has a wider range of applications, ensuring that the angle formed between the inspection window 2 disposed on the quadrilateral side and the top of the biological pool is the same, which helps to distribute light from natural or artificial light sources more evenly, facilitating observation of the pool by operators. The triangular sides can be tilted towards the top of the biological pool or perpendicular to the top of the biological pool. The triangular cross-section of observation window 1 effectively distributes the load, improving the overall strength and durability of the structure. The fixed connection between the triangular and quadrilateral sides creates a closed space at the top of the biological treatment tank, reducing the entry of external pollutants and ensuring a stable environment within the tank. This is crucial for maintaining the effectiveness of wastewater treatment.
[0029] To make the observation window structure more stable, preferably, the observation window body 1 may include multiple keels 3, which can be set on the inner side of the quadrilateral side; and a cover 4, which is fixedly connected to the keels 3 and the top of the biological pool to form a sealed space for the observation window body 1. The number of keels 3 is at least two, preferably four. The keels 3 can enhance the load-bearing capacity of the observation window body 1. Multiple evenly distributed keels 3 can evenly bear external pressure, such as wind pressure or snow pressure, preventing the observation window from deforming under external forces; multiple keels 3 can ensure the flatness of the observation window body 1, avoid deformation, and store sewage or debris outside the observation window body 1; it can also improve the safety of the observation window and facilitate installation. The cover 4 can be fixedly connected to the keels 3 by welding or bolting, preferably by welding. Welding the cover 4 directly to the keels 3 can provide stronger connection strength and stability, enhance the load-bearing capacity of the overall structure, and reduce loosening caused by vibration or external forces. Meanwhile, the welded connection improves sealing, reduces maintenance needs, simplifies the installation process, and enhances the aesthetics. The aforementioned cover 4 can be fixedly connected to the top of the biological tank using bolts. Bolted connections are suitable for biological tanks of various materials, facilitating installation and disassembly, offering good adjustability and flexibility, and providing advantages such as ease of maintenance and inspection. It provides a high-strength fixation effect, ensuring structural safety and reducing stress concentration problems caused by welding.
[0030] To provide more stable structural support for the observation window 1, preferably, the keel 3 can be triangular, with its base ends fixedly overlapping the top of the biological pool sidewall and / or its base ends fixedly set on the top of the biological pool sidewall. The fixing method can be welding or bolting, preferably bolting, as it is more convenient and has no special requirements for the biological pool material. Fixing the base ends of the triangular keel 3 to the top of the biological pool sidewall enhances structural stability and load-bearing capacity, simplifies the construction process, improves sealing, and reduces material usage and cost. This connection method tightly integrates the keel 3 with the pool wall, improving the overall structural compactness and stability, while also increasing construction efficiency and ease of later maintenance.
[0031] According to a preferred embodiment of this application, in order to provide high structural strength to the observation window 1, the covering part 4 is preferably made of one of stainless steel, tempered glass, and polycarbonate, with stainless steel being the preferred material. Stainless steel has high corrosion resistance, high strength, and durability, making it suitable for harsh environments such as sewage treatment facilities. Stainless steel is easy to clean and maintain, and possesses strong fatigue resistance and toughness, ensuring stability during long-term use.
[0032] Preferably, the quadrilateral side opening of the observation window 1 forms the inspection window 2, which covers or fits into the inspection window and is movably connected to the observation window 1. The size of the inspection window is set as needed to allow observation of the entire biological tank without blind spots. The good sealing between the inspection window 2 and the observation window 1 prevents external contaminants from entering, improving safety. The movable connection allows the inspection window 2 to be easily opened, facilitating sampling during the sampling process.
[0033] To facilitate the opening and closing of the observation window, preferably, the inspection window 2 and the observation window body 1 are connected by a hinged connection, allowing the inspection window 2 to switch between open and closed states. The inspection window 2 is opened when water samples are taken or when observation is required; it is closed when observation is not needed.
[0034] To ensure that the inspection window 2 remains securely closed, preferably, the observation window 1 is also equipped with a locking device 5 for firmly closing the inspection window 2. The locking device 5 ensures that the inspection window 2 remains securely closed during use, preventing accidental opening or loosening and enhancing the overall structural safety. Through effective locking, the inspection window 2 forms a better seal, preventing external contaminants or moisture from entering. The locking device 5 restricts operation by unauthorized personnel, ensuring that only authorized personnel can open the inspection window 2, avoiding unauthorized disassembly or interference. It also stably keeps the inspection window 2 closed under environmental changes or external forces, preventing loosening due to vibration or pressure and ensuring structural stability. The locking device 5 makes the inspection window 2 more secure when closed, while allowing for convenient opening when needed, ensuring efficient operation and convenient maintenance.
[0035] The aforementioned locking device 5 can be installed at the bottom of the inspection window 2, including a handle 51, a rotating pin 52, and a fastener 53. The rotating pin 52 passes through the inspection window 2, and one-third of the fastener 53 is fixedly connected to the rotating pin 52 located inside the inspection window 2. It can fall to the bottom using its own weight, thereby locking the inspection window 2. The handle 51 is fixed to the rotating pin 52 located outside the inspection window 2. When opening, the handle 51 can be rotated to make the rotating pin 52 drive the fastener 53 to rotate, thereby opening the inspection window 2. When closing, the fastener 53 can use its own weight to drive the rotating pin 52 and the handle 51 to rotate, thereby fixing the inspection window 2.
[0036] To ensure that the inspection window 2 also possesses a certain structural strength and stability, it is preferably made of one of the following materials: plexiglass, tempered glass, polycarbonate, or a metal panel. The metal panel is stainless steel, and the preferred material for the inspection window 2 is plexiglass. Plexiglass has high transparency, and if only observation of the interior of the biological tank is required, it is not necessary to open the inspection window 2, further ensuring the safety of operators. Plexiglass also has high strength, allowing it to withstand complex external environments.
[0037] According to another aspect of this application, a biological pool is proposed, which includes a pool body and an observation window disposed above the pool body, the observation window being the one described above.
[0038] The preferred embodiments of this application have been described in detail above. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.
[0039] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.
[0040] Furthermore, various different embodiments of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed by this invention.
