[0033] Embodiment 1

[0034] As attached Figures 1 to 5 As shown, the present application provides an elevator shaft protection structure for separating sewage, including a protection unit 1 arranged on an elevator shaft opening a, and a separation unit 2 arranged at the lower end of the protection unit 1; the separation unit 2 includes a hopper 21 arranged at the lower end of the protection unit 1, a bottom plate assembly 22 arranged at the bottom of the hopper 21, and a drain valve 23 arranged on the bottom plate assembly 22.

[0035] In this embodiment, the general method of using the elevator shaft protection structure for separating sewage is as follows:

[0036] The overall structure is erected on the elevator shaft opening a, and is divided into two parts according to the function. The upper part is a protection unit 1, which can be welded with galvanized square pipes and round pipes to prevent construction workers from accidentally falling when approaching the elevator shaft. The lower part is a separation unit 2, which specifically includes a hopper 21 connected to the lower end of the protection unit 1 and a bottom plate assembly 22 for sealing the bottom of the hopper 21 and filtering sewage impurities at different heights. A drain valve 23 is arranged on the bottom plate assembly 22. The hopper 21 and the bottom plate assembly 22 can be set as iron plates, and the drain valve 23 is preferably a galvanized steel pipe; when the construction workers pour sewage mixed with stones such as washing pump pipes into the elevator shaft, solid waste such as stones are supported by the bottom plate assembly 22 to avoid falling into the bottom of the elevator shaft opening to cause pollution and waste, and the filtered liquid sewage flows to the drain valve 23 for discharge, realizing the recycling of solid waste, preventing liquid sewage from being discharged arbitrarily to pollute the environment, and providing multiple functions such as protection of personnel safety.

[0037] The bottom plate assembly 22 includes a center plate 221 arranged at the center of the hopper 21, a plurality of bottom plates 222 arranged around the center plate 221 and connected to the side walls of the hopper 21 to form a closed bottom surface, a first blocking member 223 vertically arranged on the bottom plate 222 to form a flow channel b flowing from the center plate 221 to the drain valve 23, and a plurality of second blocking plates 224 arranged at intervals on the flow channel b and with vertical heights gradually decreasing along the direction of the flow channel b. The first blocking member 223 includes a blocking side plate 2231 having one end arranged on a corner of the center plate 221 close to the drain valve 23 and the other end connected to the inner wall of the hopper 21, and a U-shaped partition 2232 arranged on the end of the blocking side plate 2231 away from the inner wall of the hopper 21 and used to enclose the center plate 221, the opening of the U-shaped partition 2232 facing the inner wall of the hopper 21 connected to the blocking side plate 2231.

[0038] In this embodiment, in order to better guide the direction of water flow and accelerate the separation of sewage, sewage is poured into the center plate 221 at the center of the bottom plate assembly 22, and the drain valve 23 is arranged on the bottom plate. The first blocking member 223 prevents the sewage from flowing directly from the center plate 221 to the drain valve 23, but flows to the drain valve 23 through the spiral flow channel b formed by the first blocking member 223 and the inner wall of the hopper, and is precipitated and filtered through multiple second blocking plates, so that impurities are retained on the center plate 221 and the bottom plate 222, and then the filtered sewage is discharged from the drain valve 23, thereby avoiding the blockage of the drain valve 23 caused by mud, sand and stones; the first blocking member 223 makes the sewage have only one direction of outlet through the U-shaped partition 2232, and the blocking side plate 2231 blocks the passage of sewage directly flowing to the drain valve 23 without filtration, which to a certain extent ensures that the sewage reaches the drain valve 23 via the farthest distance, thereby improving the filtration quality.

[0039] The protection unit 1 includes a base frame 11 arranged around the elevator shaft opening a, at least two main keels 12 arranged on the base frame 11 and extending from the corners of the base frame 11 to the center and above, and a top frame 13 arranged at the upper end of the main keel 12, connected to the main keel 12 and having a water inlet.

[0040] In this embodiment, the base frame 11 is connected to the four sides of the elevator shaft opening a to support and fix the overall structure. At least two main keels 12 extend upward and toward the center on the base frame 11, preferably four keels extend from the four corners respectively, and the upper ends of the main keels 12 are connected in sequence to form a water inlet as the top frame 13. The frame material is preferably a 10*10cm galvanized square tube, and the protection unit 1 structure is preferably a 90cm high tower type. The sewage is poured into the water inlet from the top of the top frame 13 to complete the separation.

[0041] The protection unit 1 further includes a plurality of secondary keels 14 disposed between the primary keels 12 for reinforcing the primary keels 12 .

[0042] In this embodiment, in order to further enhance the protective effect and prevent people from falling through the gaps between the purlins, a plurality of secondary purlins 14 are horizontally connected between the main purlins 12, and a 50.8 round tube is set every 25 cm in the horizontal direction as the secondary purlin 14, thereby increasing the density of the guardrail and improving the safety of the operation.

[0043] The protection unit 1 further includes a locking device 15 disposed at a side end of the base frame 11 for connecting / detaching the hopper 21 .

[0044] In this embodiment, in order to be able to selectively install the structure according to actual conditions, the protection unit 1 and the separation unit 2 are configured to be detachable and connected to each other through a locking device 15. The locking device 15 can be configured to be in various forms such as a lock, a hook, a snap, etc., and are arranged in pairs between the hopper 21 and the base frame 11.

[0045] The locking device 15 includes a first screw hole plate 151 arranged on the base frame 11, a second screw hole plate 152 arranged on the hopper 21 and located directly below the first screw hole plate 151, and a bolt A153 for connecting the first screw hole plate 151 and the second screw hole plate 152.

[0046] In this embodiment, a specific structure of the locking device 15 is disclosed, including a first screw hole plate 151 and a second screw hole plate 152 respectively arranged at the lower end of the base frame 11 and the upper end of the hopper 21. The relative positions of the rotating hopper 21 and the base frame 11 are made so that the threaded holes of the two are aligned, and they are connected using bolts A153.

[0047] The separation unit 2 also includes a connecting plate 24 arranged on the outside of the hopper 21, a screw hole embedded plate 25 arranged on the wall of the elevator shaft opening a, and a bolt B26 arranged on the connecting plate 24 and used to connect the screw hole embedded plate 25.

[0048] In this embodiment, the screw hole embedded plate 25 on the wall of the elevator shaft opening a is arranged corresponding to the connecting plate 24 on the hopper 21, and they are connected to each other using bolts B26, so that the overall structure can be stably installed on the elevator shaft opening a, avoiding movement of position due to external impact, resulting in a falling gap, resulting in inadequate protection and bringing construction risks.

[0049] The separation unit 2 further includes a lifting lug disposed on the outer side wall of the hopper 21 .

[0050] In this embodiment, in order to facilitate lifting the entire structure to achieve the purpose of unloading waste materials or recycling them, lifting ears that can be used by a crane are installed on the outside of the hopper 21.

[0051] An anti-corrosion coating is provided on the inner surface of the hopper 21 and the surface of the bottom plate assembly 22 .

[0052] In this embodiment, in order to prevent the protective structure from being damaged by wind, sun, or sewage, an anti-corrosion layer is provided on the surface of the protective structure to extend its service life.

[0053] Embodiment 2

[0054] As a further preferred embodiment of the first embodiment, the difference of this embodiment is that a movable connection device is added, such as the attached Figure 6 As shown, the details are as follows:

[0055] The separation unit 2 further includes a movable connection device 27 which is disposed at the connection between the central plate 221 and the ramp 222 and is used to connect / detach the central plate 221 and the ramp 222 .

[0056] In this embodiment, after the sewage is poured into the separation unit 2, some stones, residues and other garbage will remain on the bottom plate assembly 22 and need to be recycled. It is very inconvenient to flip the hopper 21. In addition, the application scenario of this application is an elevator shaft, and the protective structure is large in size. Therefore, a movable connection device 27 is provided at the connection between the center plate 221 and the ramp 222. By switching the movable connection device 27, the center plate 221 and the ramp 222 can be separated / connected, so that the waste residue can be unloaded more conveniently.

[0057] The movable connection device 27 includes a convex edge 271 arranged on the side of the center plate 221 and parallel to the ramp 222, a slot 272 arranged on the convex edge 271, a protrusion 273 arranged on the ramp 222 and passing through the slot 272, a through hole 274 arranged on the protrusion 273, and a bolt C275 arranged on the protrusion 273 and passing through the through hole 274.

[0058] In this embodiment, a convex edge 271 is formed on the side of the center plate 221 to intersect with the protrusion 273. The protrusion 273 passes through the slot 272 to form a pre-locking. The through hole 274 is set as a threaded hole. The bolt C275 is a stud bolt, which is installed on the through hole 274 to complete the locking. Conversely, by removing the bolt C275 and pulling the protrusion 273 out of the slot 272, the center plate 221 can be separated from the base plate assembly 22 to achieve unloading.

[0059] The movable connection device added in this embodiment has the following advantages: the fixed structure of the above embodiment is transformed into a movable connection structure, which not only ensures the sewage separation function, but also further facilitates the unloading of waste stones in the sewage and improves the on-site construction efficiency.

[0060] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
