Description

Technical Field

[0001] The invention belongs to the technical field of rainwater grates, and specifically relates to an integrated sewage intercepting intelligent rainwater grate. Background Art

[0002] Rainwater grates are an important drainage facility, which are widely used in densely populated areas such as urban roads, residential areas, commercial streets, streets, and various municipal projects. The main function of the rainwater grate is to connect the rainwater outlet with the underground rainwater pipe, allowing the concentrated rainwater to be discharged from the drainage outlet on the municipal road surface to the rainwater collection pipe. At the same time, it also plays a filtering role, preventing weeds and branches and other debris from entering the gutter, thereby avoiding clogging the gutter. In places such as car washes, rainwater grates can also prevent water splashing and ground water accumulation, which is convenient for daily use.

[0003] In some important places or areas prone to water accumulation, rain grates sometimes cannot meet drainage needs, resulting in serious water accumulation in the area. Workers are required to go to the site to lift up the rain grates to improve drainage efficiency, thereby achieving the drainage effect; however, this method has the following problems: First, some areas are relatively hidden, and when serious water accumulation occurs, they cannot be discovered in time, which may cause economic losses and safety hazards after the water accumulation; second, potholes will appear after the rain grate is lifted, which may easily cause safety problems; in order to solve the above problems, a rain grate that can intelligently achieve accelerated drainage is provided, and the present invention provides the following technical solutions. Summary of the invention

[0004] The purpose of the present invention is to provide an integrated sewage intercepting intelligent rainwater grate to solve the problem that the rainwater grate in the prior art cannot actively and quickly respond to accelerate drainage when drainage problems occur in the area where it is located, and requires staff to take the initiative to handle it, which poses a safety hazard and is prone to economic losses due to water accumulation.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The integrated sewage intercepting intelligent rainwater grate comprises a base, a support plate is fixed on the inner wall of the base, a hydraulic lifting device is fixedly installed on the support plate, and the hydraulic lifting device is used to drive the grate to reciprocate in the vertical direction.

[0007] As a further solution of the present invention, at least two stabilizing rods are arranged on the side of the grate, the stabilizing rods are parallel to the movement direction of the grate, one end of the stabilizing rods is fixedly connected to the grate, and the stabilizing rods are slidably connected to the base, and the stabilizing rods reciprocate in the vertical direction with the grate.

[0008] As a further solution of the present invention, a circle of stabilizing bars is provided on the side of the grate, and the gap between two adjacent stabilizing bars can filter the main garbage.

[0009] As a further solution of the present invention, the intelligent rainwater grate further includes a high-definition camera unit for collecting image information within a certain range of the integrated sewage interception intelligent rainwater grate and its surroundings;

[0010] An information transmission unit, used to transmit the image information collected by the high-definition camera unit to an information processing center;

[0011] An information processing center is used to receive image information collected by the high-definition camera unit and process it to determine the depth of water accumulation at the location of the smart rain grate;

[0012] The lifting height of the grate is determined according to the depth of water accumulation.

[0013] As a further solution of the present invention, the method for the information processing center to determine the lifting height of the grate is:

[0014] The first step is to mark the rain grate and a certain range around it as the water accumulation monitoring area;

[0015] The second step is to acquire image information in the waterlogging monitoring area through a high-definition camera unit, and the information processing center processes the image information to obtain the distribution of waterlogging coverage areas in the waterlogging monitoring area;

[0016] The liquid level height above the rainwater grate is obtained according to the distribution of the water accumulation coverage area in the water accumulation monitoring area;

[0017] In the third step, when it is detected that the liquid level height d is greater than the preset threshold value dy, the hydraulic lifting device drives the grate to lift up to a height n, where n is a preset value.

[0018] As a further solution of the present invention, the method for the information processing center in the second step to obtain the distribution of the waterlogged area is:

[0019] The images of the waterlogging monitoring area at two different angles are obtained by a high-definition camera unit;

[0020] Preprocess the images of the waterlogging monitoring area obtained at two angles to obtain the gray value matrix corresponding to each image;

[0021] The two gray value matrices are compared and differentiated, and the area with greater difference is marked as the water accumulation area.

[0022] As a further solution of the present invention, a method for determining the liquid level height d above the rainwater grate according to the distribution of the water accumulation coverage area in the water accumulation monitoring area is:

[0023] Stp1. Select several points in the waterlogging monitoring area as height measurement points, where the height measurement points are the highest points within a certain range;

[0024] Stp2. After obtaining the waterlogging coverage area in the waterlogging monitoring area, determine whether each height measuring point is in the waterlogging coverage area according to the position coordinates of each height measuring point;

[0025] Obtain the height of each height measuring point covered by the water-covered area and the height of each height measuring point not covered by the water-covered area;

[0026] Get the heights of the x highest height measuring points among the height measuring points covered by the waterlogged area, and take their average as dp1; get the heights of the x lowest height measuring points among the height measuring points not covered by the waterlogged area, and take their average as dp2;

[0027] The liquid level height d is calculated according to the formula d=(dp1+dp2) / 2, where x is a preset value.

[0028] As a further solution of the present invention, the liquid level height d in the water accumulation monitoring area is continuously monitored, and the lifting height of the hydraulic lifting device is adjusted according to the change of the liquid level height d.

[0029] As a further solution of the present invention, when the grate is in a raised state, if the information processing center detects that the liquid level height d is less than a preset threshold value dy1 for a continuous preset time length t1, the information processing center inputs a reset control signal to the hydraulic lifting device through the information transmission unit, and the hydraulic lifting device drives the grate to reset when receiving the reset control signal.

[0030] As a further solution of the present invention, the telescopic end of the hydraulic lifting device and the grate are fixedly connected by a tension sensor. During the resetting process of the grate, if the detection value of the tension sensor is greater than the preset tension threshold Ny1, it is considered that there is an abnormality and an alarm is issued to remind the staff to handle it.

[0031] Beneficial effects of the present invention:

[0032] 1. The present invention provides a split structure of a base and a grate, and provides a stabilizing rod at the edge of the base and the grate. On the one hand, it can provide stability support for the split structure of the base and the grate, and on the other hand, it establishes a screen structure, which can have a filtering effect even when the grate is lifted, thereby preventing large garbage from entering the drainage channel.

[0033] 2. Compared with the method of directly setting a liquid level sensor or the like to measure the liquid level, the laying of the rain grate of the present invention does not require laying other liquid level measuring devices on the ground, and is more suitable for the rain grate laying environment.

[0034] 3. The present invention monitors the water accumulation in the environment where the rainwater grate is located in real time. When the water accumulation is deep and the normal working state of the rainwater grate cannot meet the drainage demand, the grate is automatically lifted to expand the drainage opening, thereby improving the drainage efficiency. Compared with the traditional rainwater grate working plan, it can realize unmanned adaptive adjustment, thereby realizing a rapid and effective response to the water accumulation problem, reducing the safety hazards and economic losses caused by the water accumulation.

[0037] Figure 2 It is a flow chart of the method for adjusting and determining the height of the grate by the information processing center. DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Integrated sewage interception intelligent rainwater grate, such as Figure 1 As shown, it includes a base 1, the shape and size of the base 1 are set according to the shape and size of the grate 2. If the grate 2 adopts a rectangular structure, the base 1 adopts a rectangular frame structure. If the grate 2 adopts a circular structure, the base 1 adopts a circular frame structure.

[0040] A support plate 3 is fixed on the inner wall of the base 1, and a hydraulic lifting device 4 is fixedly installed on the support plate 3. The hydraulic lifting device 4 is used to drive the grate 2 to reciprocate in the vertical direction;

[0041] The hydraulic lifting device 4 is preferably an oil cylinder, the end of the telescopic shaft of the oil cylinder is fixedly connected to the grate 2, the oil cylinder runs smoothly, and in the process of driving the grate 2 to move, its movement is limited to a certain range in the vertical direction, and is not easily disturbed, which is conducive to the overall stable operation of the rainwater grate.

[0042] In order to improve the stability of the grate 2 when the hydraulic lifting device 4 drives the grate 2, at least two stabilizing bars 5 are provided on the side of the grate 2, the stabilizing bars 5 are parallel to the movement direction of the grate 2, one end of the stabilizing bars 5 is fixedly connected to the grate 2, and the stabilizing bars 5 are slidably connected to the base 1, and the stabilizing bars 5 can reciprocate in the vertical direction;

[0043] In a specific embodiment, a strip-shaped hole is provided on the stabilizing rod 5 along its length direction, and a limiting protrusion is provided on the inner wall of the base 1 corresponding to the strip-shaped hole;

[0044] In another specific embodiment, a sliding groove is provided on the inner wall of the base 1 corresponding to the stabilizing rod 5, and the stabilizing rod 5 is slidably engaged in the sliding groove;

[0045] Preferably, a circle of stabilizing bars 5 is provided on the side of the grate 2, and the gap between two adjacent stabilizing bars 5 can filter the main garbage. In this way, when the grate 2 is lifted to improve the drainage capacity, the stabilizing bars 5 can also play a filtering effect, preventing large-volume debris and garbage such as branches that are easy to cause blockage in the drainage pipe from entering the sewer pipe and affecting the normal drainage.

[0046] In order to ensure the stable and independent operation of the integrated sewage interception intelligent rainwater grate, the integrated sewage interception intelligent rainwater grate of the present invention further includes a battery and a solar panel for charging the battery, and the battery supplies energy for the hydraulic lifting device 4; therefore, in areas where wiring is difficult or the wiring cost is high, a stable and lower-cost electrical laying method can be achieved;

[0047] In order to realize the intelligent operation of the integrated sewage interception intelligent rainwater grate, the integrated sewage interception intelligent rainwater grate of the present invention further includes a high-definition camera unit, which is powered by a power grid or a battery according to the electrical laying conditions, and is used to collect image information of the integrated sewage interception intelligent rainwater grate and a certain range around it;

[0048] An information transmission unit, used to transmit the image information collected by the high-definition camera unit to an information processing center;

[0049] An information processing center is used to receive image information collected by the high-definition camera unit and process it to determine the depth of water accumulation at the location of the smart rain grate;

[0050] It is also used to adjust and determine the height of the grate 2 according to the depth of accumulated water.

[0051] like Figure 2 As shown, the method for the information processing center to adjust and determine the height of the grate 2 includes the following steps:

[0052] The first step is to mark the rain grate and a certain range around it as a water accumulation monitoring area. The demarcation of the water accumulation monitoring area is determined according to the installation location of the rain grate and the surrounding environment. Specifically, the degree of water accumulation in the demarcated water accumulation monitoring area should be related to the depth of water accumulation at the location of the rain grate;

[0053] The second step is to collect image information in the waterlogging monitoring area through a high-definition camera unit, and transmit it to an information processing center through an information transmission unit. The information processing center processes the image information to obtain the distribution of waterlogging coverage areas in the waterlogging monitoring area.

[0054] The liquid level height above the rainwater grate is obtained according to the distribution of the water accumulation coverage area in the water accumulation monitoring area, wherein the liquid level height above the rainwater grate refers to the height difference between the top surface and the bottom surface, with the upper surface of the grate 2 in the rainwater grate as the bottom surface and the liquid surface above the grate 2 as the top surface;

[0055] Specifically, the information processing center processes the image information to obtain the distribution of the waterlogging coverage area in the waterlogging monitoring area as follows:

[0056] The image of the waterlogging monitoring area is acquired through a high-definition camera unit. Specifically, two high-definition cameras with different shooting angles can be used for image acquisition, or images at two shooting angles can be acquired by changing the shooting angle of one camera;

[0057] Preprocess the images of the waterlogging monitoring area obtained at two angles to obtain the gray value matrix corresponding to each image;

[0058] The two gray value matrices are compared and differentiated, and the area with greater difference is marked as the water accumulation area.

[0059] Specifically, the method for determining the liquid level height d above the rainwater grate according to the distribution of the water coverage area in the water monitoring area is:

[0060] Stp1. After installing the rainwater grate, delineate the waterlogging monitoring area and select several points in the waterlogging monitoring area as height measurement points. It should be noted that the height measurement point is the highest point within a certain range;

[0061] A specific solution of the present invention provides a method for obtaining a height measurement point as follows:

[0062] Several circular areas with a radius of a preset value r are randomly delineated in the waterlogging monitoring area, and the highest point in each circular area is selected as the height measurement point.

[0063] Stp2. After obtaining the waterlogging coverage area in the waterlogging monitoring area, determine whether each height measuring point is in the waterlogging coverage area according to the position coordinates of each height measuring point;

[0064] Obtain the height of each height measuring point covered by the water-covered area and the height of each height measuring point not covered by the water-covered area;

[0065] Get the heights of the x highest height measuring points among the height measuring points covered by the waterlogged area, and take their average as dp1; get the heights of the x lowest height measuring points among the height measuring points not covered by the waterlogged area, and take their average as dp2;

[0066] The liquid level height d is calculated according to the formula d=(dp1+dp2) / 2;

[0067] It should be noted that the height here refers to the height with the grate 2 as the bottom surface;

[0068] The value range of x is greater than 1, preferably 3, which can reduce errors and avoid water accumulation in local areas due to special reasons affecting the detection accuracy.

[0069] Compared with the method of directly setting up a liquid level sensor or the like to measure the liquid level, the laying of the rain grate described in the present invention does not require laying other liquid level measuring devices on the ground, and is more suitable for the rain grate laying environment (the installation location of the rain grate is generally a road surface, a platform, etc., and there is no structure around it for the installation support of the liquid level measuring device, and the establishment of a separate support structure does not meet the actual needs of drainage areas such as roads and platforms).

[0070] In the third step, when it is detected that the liquid level height d is greater than the preset threshold value dy, the information processing center inputs a lifting control signal to the hydraulic lifting device 4 through the information transmission unit. After receiving the lifting control signal, the hydraulic lifting device 4 drives the grate 2 to lift up to a height n, where n is a preset value;

[0071] Furthermore, the liquid level d in the water accumulation monitoring area can be continuously monitored, and the lifting height of the hydraulic lifting device 4 can be adjusted according to the change of the liquid level d;

[0072] Specifically, if the liquid level d remains unchanged or increases after the grate 2 is lifted to drain water, the grate 2 continues to be lifted; conversely, if the liquid level d decreases after the grate 2 is lifted to drain water, the height of the grate 2 remains unchanged or is reduced.

[0073] By properly adjusting the height of the grate 2, drainage can be ensured while avoiding the influx of large volumes of garbage due to the grate 2 being lifted too high (if a dense circle of stabilizing bars 5 is not provided or the gaps between the stabilizing bars 5 are large). It can also avoid the grate 2 being lifted too high to form an obstacle that has a significant impact on the surrounding area.

[0074] Step 4: When the grate 2 is in the lifting state, if the information processing center detects that the liquid level height d is less than the preset threshold dy1 within the continuous preset time t1, the information processing center inputs a reset control signal to the hydraulic lifting device 4 through the information transmission unit, and the hydraulic lifting device 4 drives the grate 2 to reset when receiving the reset control signal;

[0075] In order to avoid the problem that the grate 2 cannot be reset due to the accumulation of garbage and debris around the base 1, the present invention can also fix the telescopic end of the hydraulic lifting device 4 and the grate 2 through a tension sensor. During the resetting process of the grate 2, if the detection value of the tension sensor is greater than the preset tension threshold Ny1, it is considered that garbage is stuck, and an alarm is triggered to remind the staff to clean up the garbage.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the invention or exceed the scope defined by the claims, they shall all fall within the protection scope of the present invention.
