Description

Technical Field

[0001] The utility model relates to a spiral grate used for a vertical grate type rainwater outlet, belonging to the technical field of road drainage. Background Art

[0002] A rainwater inlet is a structure that collects rainwater on a rainwater pipe or combined pipe. In order to prevent too much debris in the water flow from entering the rainwater pipe network, a grate is installed at the rainwater inlet to block the debris in the water flow. Rainwater grates can be classified into vertical grate type, flat grate type, and side ditch type according to their shape. Although the vertical grate type has a slightly slower drainage speed than the flat grate type, the grate is relatively deeper, can filter more debris, and is not easy to get clogged. Therefore, it is often used in occasions with a lot of debris.

[0003] After searching Chinese patent CN206722052U, a vertical rain grate is disclosed, including a rain grate body, the rain grate body includes a rectangular concrete structure, the concrete structure is provided with a drain outlet along its own thickness direction, a plurality of grate bars are fixedly installed on the drain outlet, the plurality of grate bars are arranged in parallel and at intervals, the grate bars are arranged perpendicular to the length direction of the concrete structure and both ends are cast in the concrete structure, and a drain hole for drainage is formed between adjacent grate bars, characterized in that a steel cage in the form of a rectangular frame structure is cast in the concrete structure, and the steel cage is arranged around the drain outlet. The utility model has the advantages of simple structure, low cost, and convenient manufacturing and use.

[0004] Most of the existing vertical grate rainwater outlets are similar to the above-mentioned prior art. Although the rainwater outlet is perpendicular to the ground, it can avoid the rainwater outlet from being blocked too quickly. However, when the rainwater is heavy and the flow rate of the water flowing into the rainwater outlet is fast, the debris will stick to the surface of the vertical rainwater grate under the drive of the water flow, thereby causing the drain outlet to be blocked and affecting the drainage effect. Utility Model Content

[0005] The purpose of the utility model is to provide a spiral grate for a vertical grate type rainwater outlet in order to solve the above-mentioned problem, which can filter impurities in the water flow and effectively avoid the rainwater outlet from being blocked.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a spiral grate for a vertical grate type rainwater outlet, comprising a vertical grate body, on which water inlet pipes are respectively installed, a cross support frame is installed on one side wall of the water inlet pipe, a supporting main shaft is rotatably connected to the cross support frame, a water inlet circular plate is installed at one end of the supporting main shaft, water inlet circular plates are respectively provided with water inlet grooves, and a spiral plate is installed on the side wall of the supporting main shaft.

[0007] Preferably, in order to allow rainwater to flow directly into the rainwater inlet when there is less rainwater, water inlet holes are respectively opened on the vertical grate body.

[0008] Preferably, in order to facilitate the disassembly of the water inlet circular plate and the cleaning of debris inside the water inlet pipe, a threaded rod is installed at one end of the spiral plate, a fixing nut is connected to the thread on the outer surface of the threaded rod, and the spiral plate is connected to the water inlet circular plate through the threaded rod.

[0009] Preferably, in order to prevent the water inlet circular plate from rotating relative to the supporting main shaft, limiting blocks are respectively installed on the side walls of the threaded rod, and limiting grooves are provided on the water inlet circular plate, and the limiting grooves are movably engaged with the limiting blocks.

[0010] Preferably, in order to prevent the fixing nut on the threaded rod from loosening when the spiral plate drives the supporting spindle to rotate, the direction of the thread on the threaded rod is opposite to the direction of the thread of the spiral plate.

[0011] Preferably, in order to allow debris on the water inlet circular plate to fall off more quickly, the water inlet circular plate is in an umbrella shape.

[0012] Preferably, in order to reduce the contact area between the debris and the water inlet circular plate so that the debris can leave the water inlet circular plate more smoothly, circular protrusions are respectively installed on one side wall of the water inlet circular plate.

[0013] Preferably, in order to clean up the debris remaining on the water inlet circular plate on sunny days and ensure the subsequent drainage effect, a supporting side plate is respectively installed on one side wall of the vertical grate body, and a water spray nozzle is installed on the supporting side plate.

[0014] The beneficial effects of the utility model are as follows: rainwater enters the water inlet pipe through the water inlet circular plate, and when water flows through the spiral plate, it drives the spiral plate to rotate, thereby enabling the supporting main shaft to rotate, and the supporting main shaft can drive the water inlet circular plate to rotate, and the water inlet circular plate rotates continuously, thereby preventing debris from staying on the water inlet circular plate and clogging the water inlet groove on the water inlet circular plate, and the circular protrusions installed on the water inlet circular plate can reduce the contact area between the debris and the water inlet circular plate, so that the debris can better leave the water inlet circular plate, and when the rainwater is small, the water flows directly into the rainwater outlet through the water inlet hole on the vertical grate grate body, so the rainwater outlet can effectively avoid clogging regardless of the size of the rainwater.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 As shown, a spiral grate for a vertical grate type rainwater outlet comprises a vertical grate type grate body 1, the vertical grate type grate body 1 is made of cast iron material, the surface is sprayed with plastic, and has high bearing capacity and corrosion resistance. A water inlet pipe 2 is respectively installed on the vertical grate type grate body 1, a cross support frame 3 is installed on one side wall of the water inlet pipe 2, a support main shaft 4 is rotatably connected to the cross support frame 3, a water inlet circular plate 6 is installed at one end of the support main shaft 4, a water inlet circular plate 6 is respectively provided with a water inlet groove 10, a spiral plate 5 is installed on the side wall of the support main shaft 4, and a water inlet hole 13 is respectively provided on the vertical grate type grate body 1. When the rainwater is too heavy, Water flows into the water inlet pipe 2 through the water inlet groove 10 on the water inlet circular plate 6. When water flows through the spiral plate 5, it can drive the spiral plate 5 to rotate, so that the supporting main shaft 4 can rotate. The water inlet circular plate 6 can be driven to rotate through the supporting main shaft 4. Therefore, when the water flows continuously into the rainwater outlet, the water inlet circular plate 6 can rotate continuously, which can prevent debris from staying on the water inlet circular plate 6, thereby preventing debris from clogging the water inlet groove 10 on the water inlet circular plate 6. When the rainwater is small, the water flow can directly flow in through the water inlet hole 13 on the vertical grate body 1, so that the rainwater outlet can avoid clogging regardless of the size of the rainwater.

[0022] like Figure 4As shown, a threaded rod 7 is installed at one end of the spiral plate 5, and a fixing nut is connected to the thread on the outer surface of the threaded rod 7. The spiral plate 5 is connected to the water inlet circular plate 6 through the threaded rod 7. When the water inlet circular plate 6 needs to be removed, the fixing nut on the threaded rod 7 is loosened, and then the water inlet circular plate 6 can be removed, thereby facilitating the disassembly of the water inlet circular plate 6 and cleaning the debris remaining inside the water inlet pipe 2.

[0023] like Figure 4 As shown, limiting blocks 8 are respectively installed on the side walls of the threaded rod 7, and a limiting groove 9 is provided on the water inlet circular plate 6. The limiting groove 9 is movably engaged with the limiting block 8. By engaging the limiting groove 9 of the water inlet circular plate 6 with the limiting block 8 on the threaded rod 7, it is helpful to prevent the water inlet circular plate 6 from rotating relative to the threaded rod 7.

[0024] like Figure 3 As shown, the thread direction on the threaded rod 7 is opposite to the thread direction of the spiral plate 5. The spiral direction of the spiral plate 5 is opposite to the thread direction on the threaded rod 7, so that when the spiral plate 5 drives the supporting main shaft 4 to rotate, the fixing nut on the threaded rod 7 will not loosen easily.

[0025] like Figure 3 As shown, the shape of the water inlet circular plate 6 is umbrella-shaped, that is, one side of the water inlet circular plate 6 is conical, so when the water inlet circular plate 6 rotates, when the debris rotates to the bottom of the water inlet circular plate 6, the debris on the water inlet circular plate 6 can leave the surface of the water inlet circular plate 6 more quickly.

[0026] like Figure 4 As shown, circular protrusions 14 are respectively installed on one side wall of the water inlet circular plate 6. The circular protrusions 14 installed on the water inlet circular plate 6 can reduce the contact area between debris and the water inlet circular plate 6, so that the debris can leave the water inlet circular plate 6 faster, further improving the anti-blocking effect of the water inlet circular plate 6.

[0027] like Figure 3 As shown, supporting side plates 11 are respectively installed on one side wall of the vertical grate body 1, and water nozzles 12 are installed on the supporting side plates 11. The water nozzles 12 are connected to a water pump through a water pipe. When it is sunny, water is supplied to the water nozzles 12 through the water pump, so that the water nozzles 12 can spray water to clean the surface of the water inlet circular plate 6, thereby ensuring the subsequent drainage effect of the rainwater outlet.

[0028] When the utility model is in use, when the rain is too heavy, the rainwater enters the water inlet pipe 2 through the water inlet circular plate 6, and when the water flows through the spiral plate 5, it will drive the spiral plate 5 to rotate, so that the supporting main shaft 4 can rotate, and the supporting main shaft 4 can drive the water inlet circular plate 6 to rotate, and the water inlet circular plate 6 rotates continuously, so as to prevent debris from staying on the water inlet circular plate 6 and clogging the water inlet groove 10 on the water inlet circular plate 6. In addition, the circular protrusion 14 installed on the water inlet circular plate 6 can reduce the contact area between the debris and the water inlet circular plate 6, so that the debris can better leave the water inlet circular plate 6. When the rain is small, the water flows directly into the rainwater outlet through the water inlet hole 13 on the vertical grate grate body 1, so the rainwater outlet can effectively avoid clogging regardless of the size of the rain.
