Description

Technical Field

[0001] The utility model belongs to the technical field of sponge city equipment, and in particular relates to a sponge city greening water storage system. Background Art

[0002] A sponge city is a city that can adapt to environmental changes and natural disasters caused by rainwater like a sponge. It can absorb, store, infiltrate and purify water when it rains, and release and utilize the stored water when needed, so that rainwater can migrate freely in the city. For this reason, some sponge city greening constructions are equipped with water storage systems to collect and store rainwater in order to provide water for urban greening.

[0003] A Chinese patent with publication number CN220013851U discloses a rainy day water storage device for landscaping. The solution includes a water storage tank and a filter frame rotatably connected to the bottom of the water storage tank. A detachable coarse filter screen is provided inside the filter frame, and an oblique secondary filter plate is provided inside the water storage tank. The above solution utilizes a rotatable filter frame and a coarse filter screen to filter and intercept rainwater passing through the coarse filter screen on rainy days, thereby achieving the purpose of purifying water quality.

[0004] In actual use, since the top of the filter frame in the above solution lacks a shading device, the rainwater in the water storage tank is easily evaporated and lost under strong light before being pumped out, resulting in a waste of water resources. Utility Model Content

[0005] The utility model is intended to provide a sponge city greening water storage system to solve the problem that the stored rainwater in the above solution is easily lost due to evaporation due to sunlight.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A sponge city greening water storage system comprises a water collection box, a sleeve, a water storage tank and a coarse filter screen, wherein the water collection box has an inner cavity, a plurality of openings are arranged at intervals on the top wall of the inner cavity, a fixed shaft is fixedly arranged on the top of the inner cavity top wall, a limited axis is fixedly arranged on the bottom of the inner cavity top wall along the axial direction of the fixed shaft, an inclined water pipe is arranged below the water collection box, an upper end of the water pipe is connected with the inner cavity, and a lower end of the water pipe is connected with a pool, the sleeve is arranged at the top of the water collection box along the axial direction of the fixed shaft, and the fixed shaft is located in the sleeve, and the inner wall of the sleeve is connected with the inner cavity. A clockwork spring is arranged between the side walls of the fixed shaft, the water tank is slidably sleeved on the limiting shaft, the top of the water tank is open, a traction rope is fixedly arranged on the top of the inner side of the water tank, a convex block matching with the opening is fixedly arranged on the top of the outer side of the water tank, a drainage hole is arranged at the bottom of the water tank, a through groove and a through hole matching with the traction rope are arranged on the top wall of the inner cavity above the water tank, the upper end of the traction rope passes through the through hole and is fixedly connected with the side wall of the sleeve, and the traction rope is wound around the sleeve, and the coarse filter screen is arranged on the top of the water collecting tank along the outer periphery of the sleeve.

[0008] The principle and effect of this technical solution:

[0009] During rainfall, rainwater passes through the coarse filter screen, enters the water tank through the through groove, and flows from the drain hole to the bottom of the inner cavity, and flows into the pool through the water pipe. When the amount of rainwater flowing into the through groove per unit time is greater than the amount of rainwater flowing out of the drain hole, rainwater accumulates in the water tank, and the water tank slides downward due to gravity. The traction rope drives the sleeve to rotate, thereby stretching the spring to give it a certain elastic force. After the rainfall ends, the rainwater in the water tank gradually decreases. Under the action of the spring, the sleeve rotates in the opposite direction and tightens the traction rope, pulling the water tank upward until the protrusion blocks the opening.

[0010] Through the above arrangement, the opening can be opened during rainfall to increase the amount of rainwater flowing into the water collection box per unit time. At the same time, the opening can be automatically blocked after the rainfall ends to prevent direct sunlight from shining on the rainwater in the water collection box, thereby solving the problem that the stored rainwater in the above scheme is easily evaporated and lost due to sunlight.

[0011] In the utility model, the side wall of the limit shaft is vertically provided with a slide groove, and a slider matching the slide groove is fixedly provided on the side wall of the water tank near the limit shaft, and the slider is slidably embedded in the slide groove. Through the above arrangement, the water tank can be lifted and lowered vertically to ensure that the protrusion can block the opening.

[0012] In the utility model, a funnel-shaped groove is arranged at the bottom of the inner cavity, and the upper end of the water pipe is connected with the bottom of the groove. Through the above arrangement, rainwater can be conveniently collected and transferred to avoid rainwater remaining in the water collection box.

[0013] In the utility model, a storage platform is fixedly arranged at the bottom of the inner cavity side wall above the groove, and a fine filter is fixedly arranged on the top of the storage platform. Through the above arrangement, rainwater can be further purified.

[0014] In the utility model, a brush is fixedly arranged on the outer side of the sleeve in the transverse direction.

[0015] The principle and effect of this technical solution:

[0016] When the water tank is lowered, the traction rope is pulled to drive the sleeve to rotate. The brush outside the sleeve rotates with the sleeve for at least one circle, and the brush clears the fallen leaves and other impurities that fall on the top of the coarse filter. When the clockwork spring drives the sleeve to rotate in the opposite direction, the brush rotates in the opposite direction with the sleeve and clears the fallen leaves and other impurities that fall to the top of the coarse filter with the rain.

[0017] Through the above arrangement, the sleeve is used to drive the brush to rotate and automatically clean the fallen leaves and other impurities on the top of the coarse filter, thereby reducing the number of manual cleaning times for the coarse filter and saving human resources.

[0018] In the utility model, the coarse filter screen includes a first mesh surface and a second mesh surface, the first mesh surface is provided with a convex connection block on one side close to the second mesh surface, and the second mesh surface is provided with a concave connection groove matched with the connection block on one side close to the first mesh surface. Through the above arrangement, it is convenient for workers to disassemble and assemble the coarse filter screen for cleaning.

[0019] In the utility model, the top of the through hole side wall is provided with an arc-shaped guide surface. Through the above arrangement, the traction rope can be prevented from breaking due to friction with the top of the through hole, thereby extending the service life of the utility model.
