Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety protection technology for sewage wells, and more specifically, to a safety protection device for sewage inspection wells. Background Technology
[0002] Wastewater inspection wells are manholes installed in drainage pipe systems for inspecting and cleaning pipes. They also serve to connect pipes, allowing air circulation within the pipes, preventing the accumulation of harmful gases, ensuring air quality, and facilitating the normal operation of the drainage system. To prevent pedestrians or debris from falling into wastewater inspection wells, protective measures are usually implemented at the well opening. Currently, the common method is to install protective netting at the opening. However, because protective netting is made of soft material, it is prone to collapsing or breaking under significant impact. Furthermore, the netting ages over time, becoming less stable. Therefore, we propose a safety protection device for wastewater inspection wells. Utility Model Content

[0021] Example 1
[0022] Please see Figures 1-3As shown, this embodiment provides a safety protection device for sewage inspection wells, including a connecting block 1. Multiple first connecting rods 2 are fixedly mounted on one side of the connecting block 1. A support assembly 3 is mounted on the end of each first connecting rod 2 away from the connecting block 1. The support assembly 3 includes a support rod 31, one end of which is slidably disposed inside the first connecting rod 2. A first screw 33 is rotatably mounted on the end of the first connecting rod 2 near the support rod 31 for fixing the support rod 31. One end of the first screw 33 is disposed inside the first connecting rod 2. A second connecting rod 34 is rotatably mounted on the end of the support rod 31 away from the first connecting rod 2. A fixing assembly 35 is mounted on the end of the second connecting rod 34 away from the support rod 31. The fixing assembly 35 includes a support plate 351. The center of one side of the support plate 351 is fixedly connected to the end of the second connecting rod 34 away from the support rod 31. A fixing plate 352 is provided on the side of the support plate 351 away from the second connecting rod 34. In order to prevent the fixing plate 352 from sliding after contacting the well wall, the side of the fixing plate 352 away from the support plate 351 is made of rubber. When using the device, the user first pulls a part of the support rod 31 out of the inside of the first connecting rod 2 until the fixing plate 352 contacts the well wall. Then the user tightens the first screw 33 to fix the support rod 31. In order to prevent the first screw 33 from loosening, a compression spring 32 for pressing the support rod 31 is fixedly provided inside the first connecting rod 2. One end of the compression spring 32 is fixedly connected to the support rod 31.
[0023] Please see Figures 1-4 As shown, a telescopic rod 353 is fixedly connected between the support plate 351 and the fixed plate 352. Fixed blocks 354 are provided on both sides of the telescopic rod 353, and both fixed blocks 354 are fixedly connected to the fixed plate 352. Two screws 355 are symmetrically and rotatably installed on the side of the support plate 351 away from the fixed plate 352. One end of each screw 355 is rotatably installed inside the two fixed blocks 354. The user adjusts the angle of the fixed plate 352 by rotating the connecting rod 34. Then, the user rotates the two screws 355 to make the fixed plate 352 fit tightly against the well wall. An elastic protective net is wrapped inside the connecting block 1. The upper side of the connecting block 1... The threaded connection has a cover plate 4, which is used to cover the elastic protective net. The upper side of the connecting block 1 has multiple slots, and each slot has a pull ring 5 on its outer side. Each pull ring 5 and the elastic protective net is fixedly connected with a pull rope. After the device is fixed, the user pulls the multiple pull rings 5 to pull out the elastic protective net inside the connecting block 1, and then lays the protective net flat on the upper side of the device. Multiple first connecting rods 2 are respectively set on the lower side of multiple pull rings 5. Each end of multiple support rods 31 away from the first connecting rod 2 is fixedly equipped with a buckle 6 that matches the pull ring 5. The user fixes the protective net by connecting the multiple pull rings 5 and the multiple buckles 6 respectively.
[0024] In this embodiment, the safety protection device for sewage inspection wells is used as follows: First, the user pulls a portion of the support rod 31 out from the inside of the first connecting rod 2. Then, the user tightens multiple first screws 33 to fix the multiple support rods 31. Next, the user adjusts the angle of the fixing plate 352 by rotating the second connecting rod 34, and fits the fixing plate 352 against the inner wall of the sewage inspection well. Then, the user rotates two second screws 355 to move the fixing plate 352 closer to the inner wall of the sewage inspection well, and fits it tightly against the inner wall. Then, the user unscrews the cover plate 4 and pulls multiple pull rings 5 to pull the protective net out from the inside of the connecting block 1. After the protective net is laid out, the user fixes the protective net by connecting the multiple pull rings 5 to the multiple buckles 6 respectively. This device can fit tightly against multiple parts of the inner wall of the sewage inspection well and provide stable support for the protective net, preventing the device from collapsing downwards when impacted. At the same time, it avoids the device becoming unstable after the protective net ages, thus improving the stability of the device.
