[0001] The utility model relates to the field of safety construction devices for drainage wells, and particularly relates to a safety protection mechanism for drainage operations. Background Art

[0002] For example, the utility model patent with the application number CN202320677221.7 discloses a convenient-to-maintain explosion-proof wave-eliminating drainage well, which relates to the technical field of drainage in protective engineering and includes a well body, a wave-eliminating mechanism, a sealing and pressure-bearing mechanism, and a pressure-relieving mechanism; a partition part is arranged in the well body to divide the interior of the well body into a maintenance space and a buffer space, and a water inlet pipe and a water outlet pipe are arranged outside the well body; the wave-eliminating mechanism includes a gravel cage and gravel filled in the gravel cage; the sealing and pressure-bearing mechanism includes a sealing and pressure-bearing cover plate and a sealing member, and the sealing and pressure-bearing cover plate is detachably connected to the partition part through the sealing member and arranged on the partition part; the pressure-relieving mechanism includes a first pressure-relieving hole and a second pressure-relieving hole, and a pressure-relieving pipe is arranged outside the second pressure-relieving hole. In this prior art, the general structure of the drainage well is disclosed. As Figure 1 shown, the limited space M is the internal space of the drainage well. There are two pipelines arranged on the left and right sides of the drainage well. The two pipelines are respectively used for feeding water into the drainage well (left pipeline) and discharging water from the drainage well (right pipeline 1). In the right pipeline 1, it has a water inlet end 11. In actual construction, operators need to tie a safety rope and go down into the well for operation. To ensure the safety of construction workers, an airbag is often needed to be stuffed into the left pipeline to block the left pipeline, avoid the influence of water flow on construction, and avoid the water flow from washing away the construction workers, so as to ensure construction safety. However, if there are changes in the blockage of the left pipeline (the airbag slips or ruptures), the water volume will increase instantaneously, resulting in an increase in the flowing water pressure inside the limited space well. The safety rope is not enough to ensure that the operators will not be washed away. In order to eliminate the hidden danger of being washed away. Summary of the Utility Model

Those skilled in the art can reasonably determine the specific meaning of the above words in the present utility model in combination with the specific content of the technical solution.

[0029] Referring to Figures 2 to 5 , the drainage operation safety protection mechanism of the embodiment of the present utility model includes a net bag 100 and a fixing mechanism 200. The net bag 100 is used to completely cover the water inlet end 11 of the pipeline 1; the fixing mechanism 200 is fixedly connected to the edge of the net bag 100. The fixing mechanism 200 is placed at the bottom of the well, and the fixing mechanism 200 can be telescoped up and down to adjust the installation height of the net bag 100. The net bag 100 is fixed by the fixing mechanism 200, so that the net bag 100 covers the water inlet end 11 of the pipeline 1 for water discharge, ensuring that the user cannot fall into the pipeline 1 from the water inlet end 11 and guaranteeing the personal safety of the staff working underground.

[0030] Among them, in some embodiments, the fixing mechanism 200 includes a base 210 and a telescopic rod 220. The telescopic rod 220 is vertically arranged. One end of the telescopic rod 220 is fixedly connected to the base 210, and the other end is fixedly connected to the edge of the net bag 100. The base 210 is directly placed at the bottom of the well for installation and fixation. By adjusting the installation direction, the net bag 100 and the water inlet end 11 of the pipeline 1 for water discharge are located on the same side. By adjusting the height of the telescopic rod 220, the net bag 100 is adjusted to the front of the water inlet end 11, thereby ensuring the personal safety of the staff.

[0031] Furthermore, the telescopic rod 220 includes a fixed rod 221 and a sliding rod 222. One end of the fixed rod 221 is fixedly connected to the upper surface of the base 210, and the other end is axially provided with a sliding groove 2211. One end of the sliding rod 222 extends into the sliding groove 2211 and is slidably connected to the sliding groove 2211, and the other end is fixedly connected to the edge of the net pocket 100. This structure realizes the height adjustment of the net pocket 100. In order to improve the stability of the entire mechanism and ensure that the net pocket 100 will not fall after being adjusted to the appropriate height, along the length direction of the fixed rod 221, a plurality of clamping holes 2212 are axially penetrated through the side wall of the fixed rod 221. The plurality of clamping holes 2212 are arranged at intervals. A telescopic clamping block 2223 is arranged on the side wall of the sliding rod 222. The clamping block 2223 is telescopic to disengage from the clamping hole 2212 or be clamped and matched with the clamping hole 2212. By using the detachable clamping fit of the clamping block 2223, the telescopic adjustment of the sliding rod 222 and the effect of fixing the height of the net pocket 100 are realized, the structural stability of the entire mechanism is improved, and safety is better guaranteed.

[0032] Preferably, in order to realize the detachable fit between the clamping block 2223 and the clamping hole 2212, a receiving groove 2221 is arranged on the side wall of the sliding rod 222. The clamping block 2223 is embedded in the receiving groove 2221 and can telescopically slide in the receiving groove 2221. A spring 2222 is arranged between the bottom of the receiving groove 2221 and the clamping block 2223. When the clamping block 2223 is completely embedded in the receiving groove 2221 (refer to the clamping block 2223 in the solid line part of Figure 4 ), the clamping block 2223 is disengaged from the clamping hole 2212. When the clamping block 2223 partially protrudes from the receiving groove 2221 (refer to the clamping block 2223 in the dashed line part of Figure 4 ), the clamping block 2223 protrudes from the clamping hole 2212 and is clamped and matched with the clamping block 2223. It should be emphasized that by using the elasticity of the spring 2222, a pushing force can always be generated on the clamping block 2223 towards the outside, making the clamping block 2223 more stable when it is inserted into the clamping hole 2212. When the height of the telescopic rod 220 needs to be adjusted, the clamping block 2223 can be directly pressed manually to disengage the clamping block 2223 from the clamping hole 2212 and embed it in the receiving groove 2221, so that there is no movement interference in the relative sliding between the sliding rod 222 and the fixed rod 221.

[0033] In some embodiments, referring to Figure 2 , in order to improve the strength and stability of the entire structure, a support rod 230 is arranged between the fixed rod 221 and the base 210. The support rod 230 is inclined. One end of the support rod 230 is fixedly connected to the fixed rod 221, and the other end is fixedly connected to the base 210, so that a triangular support structure is formed on the surfaces of the support rod 230, the fixed rod 221 and the base 210.

[0034] It should be noted that in the above embodiments, the fixed edge 210 and the edge of the mesh bag 100 are integrally formed. This enables the fixed edge 210 and the mesh bag 100 to be processed together during the manufacturing process, facilitating subsequent installation.

[0035] As a further improvement of the above embodiments, referring to Figure 5 , the mesh bag 100 includes a plurality of first stop lines 110 and a plurality of second stop lines 120. The plurality of first stop lines 110 are arranged in parallel and at intervals, and the plurality of second stop lines 120 are arranged in parallel and at intervals. The first stop lines 110 and the second stop lines 120 are arranged crosswise. Referring to Figure 5 , by means of the crosswise arrangement between the first stop lines 110 and the second stop lines 120, a plurality of holes are formed on the mesh bag 100. These holes are used to drain water, preventing the drainage well from being flooded by a suddenly increased amount of water and ensuring the original function of the drainage well. At the same time, the crosswise arrangement of the first stop lines 110 and the second stop lines 120 can enhance the supporting strength of the entire mesh bag 100. Thus, when a construction worker collides directly with the mesh bag 100, the mesh bag 100 can block the construction worker, ensuring the construction safety of the worker. In order to improve the strength and deformation ability of the mesh bag 100, both the first stop lines 110 and the second stop lines 120 are elastic.

[0036] To further enhance the strength of the entire mesh bag 100, the intersection of the first stop lines 110 and the second stop lines 120 is fixedly connected. This makes the connection of the entire mesh bag 100 tighter and improves the strength. At the same time, the intersection of the first stop lines 110 and the second stop lines 120 is wrapped with a heat shrinkable tube 130 in the shape of a "cross" to fixedly connect the intersection of the first stop lines 110 and the second stop lines 120. Using the heat shrinkable tube 130 to fixedly connect the intersection of the first stop lines 110 and the second stop lines 120 enhances the strength of the connection position of the mesh bag 100 and prevents the mesh bag 100 from breaking.

[0037] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
