Description

Technical Field

[0001] The present invention specifically relates to the technical field of urban drainage, and in particular is a square rain grate for sponge cities with high efficiency of flow and debris removal and warning functions. Background Art

[0002] Sponge city refers to an urban development mode that effectively controls rainwater runoff by strengthening urban planning and construction management, giving full play to the absorption, storage and slow release of rainwater by buildings, roads, green spaces, water systems and other ecological systems, and realizing natural accumulation, natural infiltration and natural purification. Currently, there are relatively few sponge elements that can be used in urban roads. The most effective ones are the sunken green belt c and the overflow stormwater outlet, namely the overflow grate. That is, the green belt between the carriageway and the sidewalk is concave, allowing rainwater to accumulate in the green belt for a period of time and then slowly released through the overflow stormwater outlet. At present, the square overflow stormwater outlet used in the green belt is made into an inclined trapezoidal box shape with a large bottom and a small top, so that the stormwater outlet can drain normally at different water levels. Rainwater enters the stormwater outlet through the gaps in the grille, and the gaps in the grille are arranged vertically upward from the base;

[0003] However, the existing rainwater inlets have the following problems:

[0004] 1. If Figures 1 to 3 As shown in FIG, the side overflow outlets of the existing square overflow grate are all perpendicular to the bottom of the side of the grate, and the rainwater flow rate is poor and is easily blocked by debris such as leaves. As a result, a large amount of debris often accumulates near the existing overflow rainwater outlet, affecting drainage and being unsightly. The debris is also difficult to clean;

[0005] 2. Since the overflow rainwater outlet is set in the green belt, far away from the pedestrian road, the existing rainwater grate cannot visually see the internal debris from a distance. When there is a lot of debris, it cannot visually warn the cleaning personnel, which affects the drainage capacity of the grate and subsequent operation and maintenance. Summary of the Invention

[0006] The purpose of the present invention is to provide a square rain grate for sponge cities with high flow rate and debris removal warning function, which solves the problem that the existing rain grate has poor flowability and cannot intuitively warn cleaning personnel when there are a lot of debris inside.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a square rain grate for sponge cities with high efficiency and impurity removal warning function, comprising a bracket, the side surface of the top of the bracket being movably connected to a grate convex cover via a hinge, the inner wall of the bracket being fixedly connected to a frame, the top of the frame being in contact with the bottom of the grate convex cover;

[0008] The front and back sides of the grate convex cover are both provided with a first horizontal overflow port, the side of the grate convex cover is provided with a vertical longitudinal overflow port, and the top of the grate convex cover is provided with a second horizontal overflow port;

[0009] The frame is connected to a debris removal prompt mechanism, which includes a dirt storage frame that rises and falls due to its own weight and an indicator column that follows the rise and fall of the dirt storage frame. The dirt storage frame is slidably connected to the frame and is located inside the frame. The dirt storage frame is provided with an overflow groove. The bottom end of the side of the grate convex cover is fixedly connected to a positioning block, and the positioning block is movably connected to the bracket through the hinge. The bottom of the positioning block is attached to the top of the bracket and / or the frame, and the indicator column passes through the positioning block from the top and bottom. A warning mechanism is installed on the positioning block, and the warning mechanism includes a contact switch in contact with the indicator column and a wireless receiving module for sending an alarm signal.

[0010] The present invention improves the overflow port on the grate cover to adapt it to water flow patterns, enhance flow capacity, and increase rainwater flow efficiency. When the dirt storage frame is full of debris, the dirt storage frame drives the indicator column down, providing intuitive instructions to cleaning and maintenance personnel. The wireless receiving module also sends an alarm signal, facilitating timely detection and cleaning and maintenance.

[0011] As the preferred design of the present invention:

[0012] The first transverse overflow port and the second transverse overflow port of the present invention are parallel to the ground, and the longitudinal overflow port is perpendicular to the bottom edge of the side surface of the grate convex cover.

[0015] The overflow groove is provided at the bottom of the dirt storage frame, and a connecting plate is fixedly connected to the side of the dirt storage frame, and a side plate is fixedly connected to the side of the connecting plate away from the dirt storage frame, the top of the side plate is fixedly connected to the bottom of the bracket, the top of the fixing rod passes through the bottom of the connecting plate and is movably connected to the connecting plate, the top of the fixing rod is fixedly connected to the bottom of the bracket, the bottom of the fixing rod is fixedly connected to the top of the fixing plate, the side of the fixing plate is fixedly connected to the side of the side plate, the spring is sleeved on the outer surface of the fixing rod, the top of the spring is fixedly connected to the bottom of the connecting plate, and the bottom of the spring is fixedly connected to the top of the fixing plate.

[0018] When there is no debris or little debris in the sewage storage frame of the present invention, under the action of the spring, the indicator column is exposed above the positioning block and can be visually observed; as the debris in the sewage storage frame increases, the weight of the sewage storage frame increases and overcomes the action of the spring and descends, and the indicator column descends with the sewage storage frame. The amount of debris in the sewage storage frame can be intuitively felt by the height of the descending indicator column; when the indicator column descends to separate from the contact switch, the squeezing force on the contact switch disappears, the contact switch rebounds, and the wireless receiving module sends an alarm signal to the receiver in the duty room after receiving the signal, reminding the cleaning of the debris, thereby visually reminding the cleaning personnel to clean up the debris.

[0026] By means of the above technical solution, the present invention provides a square rainwater grate for sponge city with high efficiency and impurity removal warning function. It has at least the following beneficial effects:

[0027] (1) The square rainwater grate for sponge city with high efficiency and debris removal warning function increases the flow efficiency of rainwater by changing the overflow ports on the front and back of the grate convex cover to horizontal ones. By changing the direction of the rainwater grate, it is most suitable for the water flow state and achieves the maximum flow capacity.

[0028] (2) The square rainwater grate for sponge city with high efficiency and debris removal warning function is equipped with a debris removal prompt mechanism. When there is a lot of debris inside the sewage storage frame, it drives the indicator column to descend, so that the green area on the indicator column is hidden inside the bracket, providing intuitive instructions to the cleaning staff, reminding them to clean.

[0029] (3) The square rain grate for sponge city with high efficiency over-flow and debris removal warning function plays a warning role on the one hand through the indicator column, and plays a role in positioning the positioning block on the other hand. Because the positioning block can only rotate with the hinge as the axis, when the indicator column is connected to the connecting rod, it will block the movement of the positioning block, so that the grate convex cover cannot be opened, which plays a role in limiting the grate convex cover. Rotating the indicator column to separate the indicator column from the connecting rod releases the restriction on the grate convex cover, and the grate convex cover can be opened, which has the function of convenient and quick positioning.

[0030] (4) The square rainwater grate for sponge city with high efficiency and debris removal warning function, when there are a lot of debris inside the sewage storage frame, the sewage storage frame drops due to its own weight, so that the block is inserted into the inside of the overflow trough, so that the baffle plays a role in supporting the sewage storage frame.

[0031] (5) The square rainwater grate for sponge city with high efficiency and debris removal warning function can be easily removed from the filter frame through the setting of the filter frame.

[0032] (6) This square rainwater grate for sponge cities with high efficiency and debris removal warning function, when there is a lot of debris inside the sewage storage frame, drives the sewage storage frame to drop so that the indicator column and the contact switch are separated, the squeezing force on the contact switch disappears, the contact switch rebounds, and controls the wireless receiving module to send a signal to the receiver in the duty room, reminding the cleaning staff to clean up the debris, which has the effect of intuitively reminding the cleaning staff to clean up the debris.

[0033] (7) The square rainwater grate for sponge city with high efficiency and debris removal warning function, when the sewage storage frame is blocked and the filter frame cannot drain water, or the water volume per unit time in the grate is large, the water is discharged through the overflow pipe, and the filter screen filters the water entering the overflow pipe to prevent blockage, thereby increasing the overflow effect. When the water flows into the grate through the overflow port, the water flows into the overflow pipe. The impact of the water flow will drive the water wheel to rotate, so that the first gear drives the second gear to rotate, and the transmission rod drives the rotating rod to rotate, so that the brush cleans the debris on the surface of the filter screen to prevent the filter screen from being blocked and increase the flow capacity. When the overflow pipe is filled with water, the water immersion alarm triggers the alarm, and the alarm signal is input into the wireless receiving module to alarm the duty room, thereby achieving the effect of timely alarm, cleaning debris and preventing blockage.

[0057] As a preferred embodiment:

[0058] The first transverse overflow port 6 and the second transverse overflow port 8 are parallel to the ground, and the longitudinal overflow port 7 is perpendicular to the bottom edge of the side surface of the grate convex cover 2 .

[0059] The reference of this invention is "Experimental Study on Flow Field Around Single Cylindrical Pier", Figure 11As shown in the figure, combined with the flow pattern, the flow capacity is best when the water flow is parallel to the overflow port. Therefore, the present invention changes part of the overflow port to a horizontal position, but in order to combine the actual water flow height, still retains part of the longitudinal overflow port, which increases the flow efficiency. Figures 4 to 6 As shown, by changing the overflow ports on the front and back sides of the grate convex cover 2 to be horizontal, the flow efficiency of rainwater is increased.

[0060] The impurity removal prompt mechanism 5 includes a guide rail 501, a slider 502, a dirt storage frame 504, a connecting plate 505, a fixing rod 506, a spring 507, a side plate 508 and a fixing plate 509;

[0066] The indicator column 511 serves as a warning on the one hand, and as a positioning block 9 on the other hand. Since the positioning block 9 can only rotate with the hinge 3 as the axis, when the indicator column 511 is connected to the connecting rod 510, the movement of the positioning block 9 will be blocked, so that the grate convex cover 2 cannot be opened, thereby limiting the grate convex cover 2.

The top of the indicator column 511 passes through the middle of the guide block 1002 and fits with the contact switch 1003. The top of the guide block 1002 is connected to the wireless receiving module 1004, and the wireless receiving module 1004 is electrically connected to the contact switch 1003.

[0075] When there is a lot of debris inside the dirt storage frame 504, the dirt storage frame 504 is driven down to separate the indicator column 511 from the contact switch 1003, the squeezing force on the contact switch 1003 disappears, the contact switch 1003 rebounds, and the wireless receiving module 1004 is controlled to send a signal to the receiver in the duty room, reminding the cleaning of the debris, which has the effect of intuitively reminding the cleaning staff to clean up the debris.

[0076] An overflow mechanism 11 is provided in the pollution storage frame 504. The overflow mechanism 11 includes an overflow pipe 1101, a water-driven wheel 1102, a first gear 1103, an arc-shaped overflow cover 1104, a filter 1105, a second gear 1106, a transmission rod 1107, a first bevel gear 1108, a second bevel gear 1109, a rotating rod 1110, a cross 1111, a brush 1112, and a water immersion alarm 1113.

[0077] The bottom of the overflow pipe 1101 passes through the middle of the bottom of the filter frame 516 and is fixedly connected to the filter frame 516. The bottom of the overflow pipe 1101 passes through the middle of the bottom of the pollution storage frame 504 and is movably connected to the pollution storage frame 504.

[0078] When the internal blockage of the pollution storage frame 504 causes the filter frame 516 to be unable to discharge water, or the water flow rate per unit time inside the grate is large, the water is discharged through the overflow pipe 1101, and the filter screen filters the water entering the overflow pipe 1101 to prevent blockage, thereby increasing the overflow effect. When the water flows through the overflow port and enters the grate, the water flows into the overflow pipe 1101, and the impact of the water flow drives the water wheel 1102 to rotate, causing the first gear 1103 to drive the second gear 1106 to rotate, causing the transmission rod 1107 to drive the rotating rod 1110 to rotate, causing the brush 1112 to clean the debris on the surface of the filter screen 1105 to prevent the filter screen 1105 from being blocked, thereby increasing the flow capacity. When the overflow pipe 1101 is filled with water, the water immersion alarm 1113 triggers the alarm, and inputs the alarm signal to the wireless receiving module 1004 to alarm the duty room, thereby achieving the effect of timely alarm, cleaning debris and preventing blockage.

[0079] During use, when the cleaning staff observes that only the red layer of the indicator column 511 is leaking onto the ground or receives the warning information sent by the wireless receiving module 1004, they rotate the indicator column 511 to separate the indicator column 511 from the connecting rod 510, open the grate convex cover 2, pull out the filter frame 516, and clean the debris inside the filter frame 516.

[0080] The above is a detailed introduction to the square rainwater grate for sponge cities with high efficiency over-flow and impurity removal warning function provided by the present invention.
