Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a waterproof observation window for a biochemical pool. Background Art

[0002] A stainless steel arched cover is built above the biochemical pool to prevent rainwater and other impurities from falling into the biochemical pool and affecting the biochemical pool's sewage treatment effect. However, the setting of the cover makes it impossible for the staff to check the situation inside the biochemical pool, so an observation window needs to be opened on the cover.

[0003] However, the existing observation window is only a simple opening on the top cover, and has poor waterproof effect, and still has the problem of affecting the sewage treatment effect of the biochemical pool. Utility Model Content

[0004] The utility model aims to provide a waterproof observation window for a biochemical pool, which provides an observation port for the biochemical pool and has a good waterproof function to ensure the sewage treatment effect of the biochemical pool.

[0005] The technical solution adopted by the utility model is a waterproof observation window for a biochemical pool, comprising a window and a window cover, wherein an annular plate is connected to the bottom of the window by means of a screw seal, a portion of the annular plate extends toward the window, and a portion forms an annular boss, the window cover seal is closed on the annular boss and is locked by a locking mechanism, an annular drainage groove is arranged on the annular boss close to the edge of the window, the annular drainage groove is connected to a drainage pipe, and the drainage pipe drains water to a lower place.

[0006] Preferably, the locking mechanism includes a locking screw and a nut. A limit clamp is provided at the bottom of the locking screw. The limit clamp is inserted into the groove at the bottom of the annular plate. After the upper end of the locking screw extends out of the window cover, it is locked with a nut, and a gap is maintained between the locking screw and the inner edge of the annular plate.

[0007] Preferably, a direction indicator mark is provided at the top end of the locking screw, and the direction of the direction indicator mark is the same as the direction of the limit card platform.

[0008] Preferably, a sealing gasket is provided between the window cover and the annular plate, and a double sealing rubber ring is provided on the sealing gasket, and the double sealing rubber ring is inserted into the double slots on the window cover.

[0009] Preferably, a handle is provided on the top of the window cover.

[0010] Compared with the prior art, the beneficial effect of the utility model is that an annular plate is arranged at the bottom of the window, part of the annular plate extends toward the window, and part of it forms an annular boss, the window cover is sealed on the annular boss and locked by a locking mechanism, an annular drainage groove is arranged on the annular boss close to the edge of the window, the annular drainage groove is connected to a drainage pipe, and the drainage pipe drains water to a lower place. The observation window of this structure not only meets the observation requirements of the biochemical pool, but also has a waterproof function, thereby preventing water from entering and affecting the sewage treatment effect of the biochemical pool.

[0014] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0015] Example 1

[0016] See also Figure 1-3 A waterproof observation window for a biochemical pool includes a window 1 and a window cover 2. The bottom of the window 1 is sealed and fixedly connected with an annular plate 3 by screws. Part of the annular plate 3 extends toward the window 1, and part of it forms an annular boss. The window cover 2 is sealed on the annular boss and locked by a locking mechanism. An annular drainage groove 4 is arranged on the annular boss close to the edge of the window. The annular drainage groove 4 is connected with a drainage pipe 5, and the drainage pipe drains water to a lower place.

[0017] The locking mechanism includes a locking screw 6 and a nut 7. A limited clamping platform 8 is arranged at the bottom of the locking screw 6. The limited clamping platform 8 is clamped into the clamping groove 9 at the bottom of the annular plate 3. After the upper end of the locking screw 6 extends out of the window cover 2, it is locked by the nut 7. The locking screw 6 and the inner edge of the annular plate 3 maintain a gap. The locking mechanism is fast and reliable in locking. The limited clamping platform 8 abuts against the annular plate 3, which can improve the sealing between the annular plate 3 and the window cover 2. When in use, the locking screw 6 is rotated, the limited clamping platform 8 is aligned with the clamping groove 9, the locking screw 6 is lifted, the limited clamping platform 8 is clamped into the clamping groove 9, and the nut 7 is locked to complete the locking operation.

[0018] Furthermore, a direction indicator mark is provided at the top end of the locking screw 6, and the direction of the direction indicator mark is the same as the direction of the limit card platform 8, so that the limit card platform 8 can be quickly and conveniently inserted into the card slot 9, thereby improving the installation efficiency.

[0019] A sealing gasket 10 is arranged between the window cover 2 and the annular plate 3. A double sealing rubber ring 11 is arranged on the sealing gasket 10. The double sealing rubber ring 11 is inserted into the double card groove on the window cover 2. Under the action of the locking mechanism, the sealing structure has a better sealing effect.

[0020] A handle 12 is provided on the top of the window cover 2 to facilitate taking off the window cover 2 for inspection.

[0021] The above-mentioned embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the scope of the utility model. Without departing from the design spirit and principle of the utility model, various modifications and improvements made by those skilled in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
