Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and more specifically, to an inspection chamber for a sealed liquid tank. Background Technology

[0002] Covered liquid tanks are important facilities in environmental engineering for treating leachate generated from landfills and other sites. They are typically used to collect, store, and regulate the flow and composition of leachate for subsequent treatment. Inspection chambers allow operators to directly observe the internal operating conditions of the covered liquid tank, such as water quality, liquid level changes, and sediment accumulation. This is crucial for timely detection of potential problems and evaluation of treatment effectiveness.

[0003] The existing device has the following shortcomings: (1) It is inconvenient to conduct sampling surveys. During the use of the existing device, the bin cover needs to be opened so that the staff can come into contact with the leachate and take samples of the leachate. However, since the landfill leachate usually produces a large amount of foul-smelling harmful gases, the foul-smelling gases will affect the working state of the staff after the bin cover is opened, which is not good for the health of the staff.

[0004] (2) Poor sealing effect. Since the cover is usually placed directly on the top of the inspection chamber, it is easy for sewage or harmful gases to leak out of the regulating tank, causing pollution or harm to the surrounding environment and personnel.

[0005] Therefore, there is an urgent need for an inspection chamber for sealed liquid pools to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of current methods that make sampling and investigation inconvenient, and the problems that malodorous gases affect the working conditions of staff and are detrimental to their health.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] An inspection chamber for a capped liquid pool includes a base plate and further includes,

[0009] The geomembrane is welded and fixed to the top of the base plate, and a single-track extrusion weld is welded and fixed at the connection between the geomembrane and the base plate.

[0010] A cover box is welded and fixed to the bottom end of the base plate, and foam blocks are installed inside the cover box;

[0011] The inspection chamber is welded and fixed to the top of the base plate, and the outer sides of the inspection chamber are all fixed to the reinforcing plates connected to the base plate.

[0012] A cover is fitted onto the top of the sampling structure. A hinge connected to the inspection chamber is installed at the bottom of one side of the cover, and a handle is installed on the other side of the cover.

[0013] A sealing structure is installed between the cover and the inspection chamber to seal the cover and the inspection chamber.

[0014] A sampling structure is set on one side of the top of the bin cover. The sampling structure includes a transparent shell fixed to the top of the bin cover, a water suction hose installed at the bottom of the transparent shell, a reinforcing sleeve fixed to the outside of the bottom of the transparent shell, a valve fixed to one side of the transparent shell, a drain pipe installed on one side of the valve, and a transmission assembly set at the top of the transparent shell.

[0015] As a preferred technical solution of this application, the transmission assembly includes a rubber piston that slides inside the transparent shell, a pull rod that fixes the top of the rubber piston, a handle installed on the top of the pull rod, and a rain cover that is sleeved on the top of the transparent shell and slides on the outside of the pull rod.

[0016] As a preferred technical solution of this application, the water-absorbing hose passes through the tank cover and is connected to the transparent outer shell, and the drain pipe is connected to the transparent outer shell through a valve.

[0017] As a preferred technical solution of this application, the frontal cross-section of the rain cover has a funnel-shaped inclined structure, and the rubber piston and the transparent shell form a sliding structure.

[0018] As a preferred technical solution of this application, the sealing structure includes a second plastic magnetic strip fixed to the top of the inspection chamber, a lower rubber pad sleeved on the outside of the second plastic magnetic strip and connected to the inspection chamber, an upper rubber pad fixed to the top of the inside of the chamber cover, a first plastic magnetic strip installed inside the upper rubber pad, and extended side strips fixed to both sides of the bottom end of the upper rubber pad.

[0019] As a preferred technical solution of this application, the first plastic magnetic strip and the second plastic magnetic strip are located on the same vertical center line, and the first plastic magnetic strip and the second plastic magnetic strip are magnetically connected.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the scheme of this application:

[0022] By pulling the handle, the rubber piston moves upward, drawing the leachate into the transparent shell, allowing staff to observe the color and turbidity of the leachate. Rotating the valve allows the liquid to be discharged through the drain pipe for sampling, thus realizing the convenient sampling function of this device. It is convenient to sample the leachate without opening the cover. At the same time, the gas inside the device is not easily discharged, ensuring the work efficiency and physical and mental health of the staff.

[0023] The magnetic force of the first and second plastic magnetic strips causes the upper and lower rubber pads to fit tightly together, sealing the gap between the chamber cover and the inspection chamber. This achieves the connection and sealing function of the device, ensuring a tight connection between the inspection chamber and the chamber cover, and preventing sewage or harmful gases from leaking out of the regulating tank and causing pollution or harm to the surrounding environment and personnel.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1-4 As shown, the inspection chamber for a sealed liquid pool proposed in this embodiment includes a base plate 1, and further includes...

[0031] Geomembrane 2 is welded and fixed to the top of the base plate 1, and a single-track extrusion weld 3 is welded and fixed at the connection between the geomembrane 2 and the base plate 1.

[0032] The covering box 11 is welded and fixed to the bottom end of the base plate 1, and a foam block 10 is installed inside the covering box 11;

[0033] The inspection chamber 8 is welded and fixed to the top of the base plate 1, and the outer side of the inspection chamber 8 is fixed to the reinforcing plate 9 connected to the base plate 1.

[0034] The cover 5 is fitted onto the top of the sampling structure 6. A hinge 12 connected to the inspection chamber 8 is installed at the bottom of one side of the cover 5, and a handle 7 is installed on the other side of the cover 5.

[0035] The sealing structure 4 is disposed between the cover 5 and the inspection chamber 8 and is used to seal the cover 5 and the inspection chamber 8.

[0036] The sampling structure 6 is located on one side of the top of the cover 5. The sampling structure 6 includes a transparent shell 604 fixed to the top of the cover 5, a water suction hose 601 installed at the bottom of the transparent shell 604, a reinforcing sleeve 602 fixed to the outside of the bottom of the transparent shell 604, a valve 608 fixed to one side of the transparent shell 604, a drain pipe 609 installed on one side of the valve 608, and a transmission assembly located at the top of the transparent shell 604.

[0037] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the transmission assembly further includes a rubber piston 603 sliding inside the transparent housing 604, a pull rod 607 fixing the top of the rubber piston 603, a handle 606 installed on the top of the pull rod 607, and a rain cover 605 sleeved on the top of the transparent housing 604 and sliding outside the pull rod 607. The water suction hose 601 passes through the cover 5 and is connected to the transparent housing 604. The drain pipe 609 is connected to the transparent housing 604 through a valve 608. The front cross-section of the rain cover 605 has a funnel-shaped inclined structure. A sliding structure is formed between the rubber piston 603 and the transparent shell 604. By pulling the handle 606, the pull rod 607 moves the rubber piston 603 upward, forming a negative pressure cavity at the bottom of the transparent shell 604 that is fitted around the rubber piston 603. This allows the suction hose 601 to draw the leachate into the interior of the transparent shell 604. The color and turbidity of the leachate can be observed through the transparent shell 604. When sampling is required, the liquid inside the transparent shell 604 is discharged through the drain pipe 609 by rotating the valve 608, so that the staff can take samples.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in a preferred embodiment, based on the above method, the sealing structure 4 further includes a second plastic magnetic strip 405 fixed to the top of the inspection chamber 8, a lower rubber pad 401 sleeved on the outside of the second plastic magnetic strip 405 and connected to the inspection chamber 8, an upper rubber pad 402 fixed to the top of the inside of the chamber cover 5, a first plastic magnetic strip 403 installed inside the upper rubber pad 402, and extended side strips 404 fixed to both sides of the bottom end of the upper rubber pad 402. The first plastic magnetic strip 403 and the second plastic magnetic strip 405 are located on the same vertical center line. The first plastic magnetic strip 403 and the second plastic magnetic strip 405 are magnetically connected. When the cover 5 and the inspection chamber 8 are in contact, the magnetic force of the first plastic magnetic strip 403 and the second plastic magnetic strip 405 pushes the lower rubber pad 401 and the upper rubber pad 402 closer together, so that the upper rubber pad 402 and the lower rubber pad 401 are tightly fitted together, sealing the gap between the cover 5 and the inspection chamber 8 and preventing leakage. By extending the edge strip 404, the contact area between the upper rubber pad 402 and the lower rubber pad 401 is increased, improving the sealing effect.

[0039] Specifically, in use, the inspection chamber for the sealed liquid pool is welded with a single-rail extrusion welding machine to the bottom plate 1 and geomembrane 2, the covering box 11 and the bottom plate 1, and the bottom plate 1 and the inspection chamber 8 to ensure the stability of the connection. After the device is installed in the sealed liquid pool, the buoyancy of the foam block 10 keeps the inspection chamber 8 above the water surface to prevent liquid from being discharged through the inspection chamber 8. The cover 5 is turned around the hinge 12 by the handle 7 to open the inspection chamber 8, so that the staff can operate on the leachate. The leachate can be sampled through the sampling structure 6. The sealing structure 4 seals and fixes the inspection chamber 8 and the cover 5 to prevent gas and liquid from being discharged through the inspection chamber 8.

[0040] Pulling the handle 606 causes the lever 607 to move the rubber piston 603 upward, creating a negative pressure cavity at the bottom of the movable transparent housing 604 fitted on the rubber piston 603. This allows the suction hose 601 to draw the leachate into the interior of the transparent housing 604. The color and turbidity of the leachate can be observed through the transparent housing 604. When sampling is required, rotating the valve 608 discharges the liquid inside the transparent housing 604 through the drain pipe 609, facilitating sampling by staff.

[0041] When the cover 5 is in contact with the inspection compartment 8, the magnetic force of the first plastic magnetic strip 403 and the second plastic magnetic strip 405 pushes the lower rubber pad 401 and the upper rubber pad 402 closer together, making the upper rubber pad 402 and the lower rubber pad 401 fit tightly together, sealing the gap between the cover 5 and the inspection compartment 8 and preventing leakage. The extended edge strip 404 increases the contact area between the upper rubber pad 402 and the lower rubber pad 401, improving the sealing effect.

[0042] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
