Description

Technical Field

[0001] The utility model relates to safety protection equipment for a sewage treatment pool, belonging to the technical field of sewage treatment. Background Art

[0002] In the process of sewage treatment, sewage treatment plants often build sedimentation tanks to purify sewage. The walls of existing sedimentation tanks are mostly deep. Therefore, when using sedimentation tanks, it is often necessary to weld guardrails around the sedimentation tanks to protect the sedimentation tanks. The guardrails are provided with outward-opening doors for easy entry and exit of staff.

[0003] However, in daily use, the sewage treatment pool is equipped with water pumps and other components. When the water pumps and other components need to be replaced, they cannot be transported out from the outer door of the guardrail due to their size and can only be transported out from above the guardrail.

[0004] Because the height of the guardrail is too high, it is inconvenient to adjust the height, and the guardrail is not easy to disassemble and install. This series of factors will affect the operator's replacement of components such as the water pump, causing inconvenience to the work.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0012] Furthermore, there are four guardrail outer frames, which are arranged opposite to each other in pairs, and the guardrail outer frames can be lifted and lowered in the vertical direction in the rectangular groove.

[0013] Furthermore, the height of the guardrail outer frame is less than the depth of the rectangular groove.

[0014] Furthermore, the bottom end of the column is fixed to the bottom of the rectangular groove, and the top end of the column extends out from the upper end surface of the rectangular groove.

[0015] Furthermore, the height of the column is greater than the sum of the height of the outer frame of the guardrail and the depth of the rectangular groove.

[0016] Furthermore, two cylindrical linear slide rails are correspondingly installed on each column, and the two cylindrical linear slide rails are vertically arranged on both sides of the column.

[0017] Furthermore, the two sliders are arranged up and down, the top end of the upper slider is arranged flush with the upper end surface of the guardrail outer frame, and the bottom end of the lower slider is arranged flush with the lower end surface of the guardrail outer frame.

[0020] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0021] The outer frame of the guardrail is installed in a rectangular groove outside the sewage treatment tank. The driving motor can drive the outer frame of the guardrail to rise and fall along the column through the cooperation of the lead screw and the nut. The stability of the lifting process of the outer frame of the guardrail is ensured by the cooperation of the slider and the cylindrical linear slide rail. After the outer frame of the guardrail rises, it is enclosed around the outer periphery of the sewage treatment tank to play a safety protection function. When the sewage treatment tank is inspected and maintained and equipment needs to enter and exit, the driving motor can be reversed to hide the corresponding outer frame of the guardrail in the rectangular groove to facilitate the transportation of equipment in and out.
