Description

Technical Field

[0001] The invention relates to the technical field of garbage cleaning, and in particular to a water inlet cleaning system for a water conservancy and hydropower dam. Background Art

[0002] The water inlet of a hydropower dam is an important part of the dam. Its smoothness directly affects the stability of the dam's water flow and the control of the water level. By regularly cleaning the garbage at the water inlet, the normal operation of the dam can be ensured and the potential safety hazards of the dam caused by blockage or pollution of the water inlet can be reduced. Traditional methods of cleaning the water inlet of a hydropower dam usually require a lot of manpower and have the problem of low cleaning efficiency. Especially in the case of the water inlet of a large dam, the cleaning cycle is long, which can easily lead to untimely cleaning of the dam and affect the normal operation of the dam.

[0003] Chinese patent application publication number: CN115726338A discloses a floating object cleaning system and cleaning method for the water inlet of a water conservancy and hydropower dam, which belongs to the field of floating object cleaning technology. It includes a dam body, and also includes: a cleaning port opened on the surface of the dam body, an adjustment plate is slidably connected to the upstream of the cleaning port, and a second water filter hole is opened on the surface of the adjustment plate; a cylinder fixedly connected to the surface of the dam body, and the output end of the cylinder is fixedly connected to a first connecting plate, and the first connecting plate is fixedly connected to the adjusting plate; a filter plate fixedly connected to the downstream of the cleaning port; a fishing frame arranged in the cleaning port, and a first water filter hole is opened on the surface of the fishing frame; a first support frame is fixedly connected to the surface of the dam body, and a lifting mechanism is fixedly connected to the surface of the first support frame, and the lifting mechanism is used to drive the fishing frame to move, and the floating objects in the cleaning port are salvaged by the fishing frame, and then the lifting mechanism is controlled to make the fishing frame rise first and then translate, so as to facilitate the transfer of floating objects in the fishing frame and improve the cleaning efficiency.

[0004] It can be seen that the existing technology has the problem of low accuracy in conducting personalized data analysis on the types of garbage, resulting in low efficiency and low quality of garbage cleaning. Summary of the invention

[0005] To this end, the present invention provides a water inlet cleaning system for a water conservancy and hydropower dam, so as to overcome the problem in the prior art that the accuracy of personalized data analysis on the types of garbage is low, resulting in low efficiency and low quality of garbage cleaning.

[0006] To achieve the above object, the present invention provides a water inlet cleaning system for a water conservancy and hydropower dam, comprising:

[0007] A garbage information acquisition module, which includes using a flow meter to detect the water flow velocity at the water inlet of a water conservancy and hydropower dam, using a moisture sensor to detect the moisture content of the garbage, and using a visual sensor to detect the representation form of the moisture content of the garbage and the uniformity of the garbage distribution;

[0008] A garbage collection module, which is connected to the garbage information acquisition module, and is used to determine the collection method according to the uniformity of garbage distribution under the condition that the water flow velocity at the water inlet of the water conservancy and hydropower dam is less than or equal to the preset water flow velocity, and to determine the collection method of garbage according to the moisture content of garbage under the condition that the water flow velocity at the water inlet of the water conservancy and hydropower dam is greater than the preset water flow velocity;

[0009] A garbage drainage treatment module, which is connected to the garbage collection module and is used to determine the drainage treatment method for the garbage according to the pollution degree of water contained in the collected garbage and the representation form of the water contained in the garbage;

[0010] A garbage classification module, which is connected to the garbage drainage treatment module and is used to classify the garbage after drainage treatment;

[0011] An adjustment module, which is connected to the garbage classification module, and is used to determine the adjustment amount of the cleaning process parameters of the water conservancy and hydropower dam water inlet according to the garbage content downstream of the water conservancy and hydropower dam detected during the period and the accuracy of the garbage classification;

[0012] Among them, the parameters of the water conservancy and hydropower dam water inlet cleaning process include the garbage collection speed and the power of the drainage treatment machine.

[0013] Furthermore, the garbage collection module determines to collect garbage by scooping nets based on a comparison result that the garbage distribution uniformity is less than or equal to a preset distribution uniformity, under the condition that the water flow velocity at the water inlet of the water conservancy and hydropower dam is less than or equal to a preset water flow velocity, or determines to collect garbage by blocking nets based on a comparison result that the garbage distribution uniformity is greater than a preset distribution uniformity.

[0014] Furthermore, the uniformity of garbage distribution is determined according to the variance of garbage density at the sampling point, and the preset uniformity of distribution is determined according to the average value of the uniformity of garbage distribution when the water flow velocity at the water inlet of the water conservancy and hydropower dam is less than or equal to the preset water flow velocity.

[0015] Furthermore, the garbage collection module determines to collect the garbage in a covering collection manner based on a comparison result that the moisture content of the garbage is less than a preset moisture content under the condition that the water flow velocity at the water inlet of the water conservancy and hydropower dam is greater than a preset water flow velocity, or determines to collect the garbage in a sealed collection manner based on a comparison result that the moisture content of the garbage is greater than or equal to the preset moisture content.

[0016] Furthermore, the garbage drainage treatment module determines to treat the garbage drainage by leachate treatment according to the comparison result that the pollution degree of water contained in the collected garbage is greater than or equal to the preset pollution degree, and the garbage drainage treatment module determines to make a secondary determination on the drainage treatment method of the garbage according to the comparison result that the pollution degree of water contained in the garbage is less than the preset pollution degree.

[0017] Furthermore, the contamination degree of the water contained in the garbage is determined according to the content of pollutants in the water contained in the garbage.

[0018] Furthermore, the garbage drainage treatment module, under the condition of determining a secondary determination of the drainage treatment method for the garbage, determines that the garbage is to be drained by a mechanical squeezing treatment method according to the characterization form of the moisture contained in the garbage being a first characterization form, or determines that the garbage is to be drained by a flipping and cutting treatment method according to the characterization form of the moisture contained in the garbage being a second characterization form, wherein the first characterization form is the first characterization form including that the garbage itself contains moisture, and the second characterization form is that the enclosed space inside the garbage contains moisture.

[0019] Further, the adjustment module determines to adjust the garbage collection speed with a first adjustment coefficient based on a comparison result that the garbage content downstream of the water conservancy and hydropower dam detected during the period is greater than or equal to a preset garbage content, and the adjustment module makes a secondary determination on whether to adjust the parameters of the water conservancy and hydropower dam water inlet cleaning process based on a comparison result that the garbage content downstream of the water conservancy and hydropower dam detected during the period is less than a preset garbage content.

[0020] Furthermore, under the condition of making a secondary judgment on whether to adjust the parameters of the water inlet cleaning process of the water conservancy and hydropower dam, the adjustment module determines to adjust the power of the drainage treatment machine with a second adjustment coefficient based on the comparison result that the accuracy of garbage classification is less than the preset accuracy.

[0021] Furthermore, the adjustment amount of the garbage collection speed is positively correlated with the garbage content downstream of the water conservancy and hydropower dam detected during the period, and the power of the drainage treatment machine is negatively correlated with the accuracy of garbage classification.

[0022] Compared with the prior art, the beneficial effect of the present invention lies in that when the water flow velocity at the water inlet of the water conservancy and hydropower dam is less than or equal to the preset water flow velocity, the present invention determines the garbage collection method according to the uniformity of garbage distribution, and improves the garbage collection efficiency by selecting a large-area collection method at the water inlet where the water flow velocity is small. If the uniformity of garbage distribution is less than or equal to the preset uniformity of distribution, it means that the garbage is evenly distributed. At this time, collecting garbage by scooping nets can clean up a large range of garbage at one time, quickly clean up a large amount of garbage floating on the water surface, and ensure smooth water flow. If the uniformity of garbage distribution is greater than the preset uniformity of distribution, it means that the garbage is unevenly distributed. At this time, using a blocking net to gather the garbage and then salvage it can reduce unnecessary resource consumption. The above method improves the accuracy of personalized data analysis of garbage types, thereby improving the efficiency and quality of garbage cleaning.

[0023] Furthermore, the present invention determines the collection method according to the moisture content of garbage under the condition that the water flow velocity at the water inlet of the water conservancy and hydropower dam is greater than a preset water flow velocity. By selecting to salvage area by area at the water inlet with a high water flow velocity, it is possible to prevent garbage from flowing into the water inlet due to the fast water flow velocity. If the moisture content of the garbage is less than the preset moisture content, it means that the garbage has a small moisture content and a light weight. At this time, a covering collection method is selected to collect the garbage, thereby preventing the garbage with a small moisture content and a light weight from being blown away due to a high external wind speed, causing the garbage to be scattered. If the moisture content of the garbage is greater than or equal to the preset moisture content, it means that the garbage has a large moisture content and a heavy weight. At this time, a sealed collection method is selected to collect the garbage. Garbage with a high moisture content may release pollutants. Selecting a sealed collection method can prevent these pollutants from entering the water body, thereby protecting the water quality. The above method improves the accuracy of personalized data analysis of garbage types, thereby improving the efficiency and quality of garbage cleaning.

[0024] Furthermore, the present invention determines the drainage treatment method for the garbage by analyzing the pollution degree of the water contained in the collected garbage. If the pollution degree of the water contained in the garbage is greater than or equal to the preset pollution degree, the leachate treatment method is selected to drain the garbage, the water contained in the garbage is squeezed out, and the squeezed water is subjected to leachate treatment to obtain drainable water, thereby avoiding the discharge of highly polluted water and causing the water environment to be polluted. If the pollution degree of the water contained in the garbage is less than the preset pollution degree, the characterization form of the water contained in the garbage is further analyzed to determine the drainage treatment method for the garbage. The above method improves the accuracy of personalized data analysis of garbage types and thus improves the efficiency and quality of garbage cleaning.

[0025] Furthermore, the present invention further analyzes the characterization form of the moisture contained in the garbage to determine the drainage treatment method for the garbage. If the characterization form of the moisture contained in the garbage is that the garbage itself contains moisture, then the garbage is drained by mechanical squeezing. If the characterization form of the moisture contained in the garbage is that the enclosed space inside the garbage contains moisture, then the garbage is drained by flipping and cutting. The above method avoids the phenomenon that the moisture contained in the garbage cannot be discharged due to inaccurate analysis of the garbage drainage treatment process, thereby improving the accuracy of personalized data analysis of garbage types.

[0026] Furthermore, the present invention determines whether to adjust the parameters of the cleaning process of the water conservancy and hydropower dam water inlet by comparing the garbage content detected downstream of the water conservancy and hydropower dam within a period with the preset garbage content. If the garbage content is greater than or equal to the preset garbage content, it means that the garbage enters the dam water inlet due to the slow speed of collecting garbage at the dam water inlet and flows downstream with the water. At this time, the first adjustment coefficient is selected to increase the garbage collection speed. If the garbage content is less than the preset garbage content, it is necessary to further determine whether to adjust the parameters of the cleaning process of the water conservancy and hydropower dam water inlet based on the accuracy of garbage classification. The above method improves the accuracy of personalized data analysis of garbage types.

[0027] Furthermore, when the present invention further determines whether to adjust the parameters of the water inlet cleaning process of the water conservancy and hydropower dam, it determines that the parameters of the water inlet cleaning process of the water conservancy and hydropower dam need to be adjusted according to the comparison result that the accuracy of garbage classification is less than the preset accuracy. The accuracy of garbage classification is less than the preset accuracy because the moisture contained in the garbage cannot be effectively discharged during the drainage treatment of the garbage, resulting in inaccurate judgment of the type of garbage during garbage classification, resulting in low accuracy of garbage classification. At this time, the second adjustment coefficient is selected to increase the power of the drainage treatment machine to effectively remove the moisture contained in the garbage. Through the above method, the accuracy of personalized data analysis of the types of garbage is improved, thereby improving the efficiency and quality of garbage treatment.

[0036] The water inlet cleaning system of a water conservancy and hydropower dam according to an embodiment of the present invention comprises:

[0037] A garbage information acquisition module, which includes using a flow meter to detect the water flow velocity at the water inlet of a water conservancy and hydropower dam, using a moisture sensor to detect the moisture content of the garbage, and using a visual sensor to detect the representation form of the moisture content of the garbage and the uniformity of the garbage distribution;

[0038] A garbage collection module, which is connected to the garbage information acquisition module, and is used to determine the collection method according to the uniformity of garbage distribution under the condition that the water flow velocity at the water inlet of the water conservancy and hydropower dam is less than or equal to the preset water flow velocity, and to determine the collection method of garbage according to the moisture content of garbage under the condition that the water flow velocity at the water inlet of the water conservancy and hydropower dam is greater than the preset water flow velocity;

[0039] A garbage drainage treatment module, which is connected to the garbage collection module and is used to determine the drainage treatment method for the garbage according to the pollution degree of water contained in the collected garbage and the representation form of the water contained in the garbage;

[0040] A garbage classification module, which is connected to the garbage drainage treatment module and is used to classify the garbage after drainage treatment;

[0041] The adjustment module is connected to the garbage classification module and is used to determine the adjustment amount of the cleaning process parameters of the water conservancy and hydropower dam water inlet according to the garbage content downstream of the water conservancy and hydropower dam detected during the period and the accuracy of garbage classification.

[0042] In the embodiment of the present invention, the moisture sensor may be an ultrasonic moisture sensor, and the visual sensor may be a camera sensor.

[0043] Specifically, under the condition that the water flow velocity at the water inlet of the water conservancy and hydropower dam is less than or equal to the preset water flow velocity, the garbage collection module determines to collect the garbage by scooping net based on the comparison result that the garbage distribution uniformity is greater than or equal to the preset distribution uniformity, or determines to collect the garbage by blocking net based on the comparison result that the garbage distribution uniformity is less than the preset distribution uniformity.

[0044] In a specific embodiment, the garbage collection module determines the collection method according to the comparison result of the garbage distribution uniformity H and the preset distribution uniformity H0 under the condition that the water flow velocity at the water inlet of the water conservancy and hydropower dam is less than or equal to the preset water flow velocity;

[0045] If H≤H0, the garbage collection module determines to collect the garbage by scooping net;

[0046] If H>H0, the garbage collection module determines to collect the garbage in a blocking collection mode;

[0047] Among them, the preset distribution uniformity H0 is the average value of the garbage distribution uniformity when the water flow velocity at the water inlet of the hydropower dam is less than or equal to the preset water flow velocity, but the above value is not limited to this, and technical personnel in this field can also adjust the value according to actual needs.

[0048] The uniformity of garbage distribution in the embodiment of the present invention can be calculated according to the following method: set sampling points of the same area at different positions of the water inlet of the hydropower dam, obtain the garbage density at each sampling point, and the garbage density can be expressed in units of quantity (number / square meter). Calculate the variance , where xi represents the garbage density at the i-th sampling point, represents the average garbage density of all sampling points, and n represents the number of sampling points.

[0049] The scoop net collection method in the embodiment of the present invention includes using a robot or a cleaning boat to salvage garbage in the form of a scoop net, and the blocking net collection method includes using a blocking net to gather garbage and then salvage it.

[0050] The present invention determines the garbage collection method according to the uniformity of garbage distribution when the water flow velocity at the water inlet of the water conservancy and hydropower dam is less than or equal to the preset water flow velocity, and improves the garbage collection efficiency by selecting a large-area collection method at the water inlet where the water flow velocity is small. If the uniformity of garbage distribution is less than or equal to the preset uniformity of distribution, it means that the garbage is evenly distributed. At this time, garbage is collected by scooping nets, which can clean up garbage in a larger area at one time, quickly clean up a large amount of garbage floating on the water surface, and ensure smooth water flow. If the uniformity of garbage distribution is greater than the preset uniformity of distribution, it means that the garbage is unevenly distributed. At this time, a blocking net is used to gather the garbage and then salvage it, which can reduce unnecessary resource consumption. The above method improves the accuracy of personalized data analysis of garbage types, thereby improving garbage cleaning efficiency and quality.

[0051] Specifically, under the condition that the water flow velocity at the water inlet of the water conservancy and hydropower dam is greater than the preset water flow velocity, the garbage collection module determines to collect the garbage in a covering collection manner based on the comparison result that the moisture content of the garbage is less than the preset moisture content, or determines to collect the garbage in a sealed collection manner based on the comparison result that the moisture content of the garbage is greater than or equal to the preset moisture content.

[0052] In a specific embodiment, the garbage collection module determines the collection method according to the comparison result of the garbage moisture content D and the preset moisture content D0 under the condition that the water flow velocity at the water inlet of the hydropower dam is greater than the preset water flow velocity;

[0053] If D<D0, the garbage collection module determines to collect garbage in a covering collection mode;

[0054] If D≥D0, the garbage collection module determines to collect garbage in a sealed collection manner;

[0055] Among them, the value range of the preset moisture content D0 is set to 40%-100%, and the value of the preset moisture content D0 is preferably 50%, but the above value is not limited to this, and technical personnel in this field can also adjust the value according to actual needs.

[0056] The present invention determines the collection method according to the moisture content of garbage under the condition that the water flow velocity at the water inlet of the water conservancy and hydropower dam is greater than the preset water flow velocity. By selecting to salvage area by area at the water inlet with a large water flow velocity, it can be prevented that the garbage flows into the water inlet due to the fast water flow velocity. If the moisture content of the garbage is less than the preset moisture content, it means that the garbage has a small moisture content and a light weight. At this time, a covering collection method is selected to collect the garbage, thereby preventing the garbage with a small moisture content and a light weight from being blown away due to a large external wind speed and causing the garbage to be scattered. If the moisture content of the garbage is greater than or equal to the preset moisture content, it means that the garbage has a large moisture content and a heavy weight. At this time, a sealed collection method is selected to collect the garbage. Garbage with a high moisture content may release pollutants. Selecting the sealed collection method can prevent these pollutants from entering the water body, thereby protecting the water quality. The above method improves the accuracy of personalized data analysis of the types of garbage, thereby improving the efficiency and quality of garbage cleaning.

[0057] Specifically, the garbage drainage treatment module determines the drainage treatment method for the garbage according to the comparison result of the pollution degree P of the water contained in the collected garbage and the preset pollution degree P0;

[0058] If P≥P0, the garbage drainage treatment module determines to treat the garbage drainage in a leachate treatment manner;

[0059] If P<P0, the garbage drainage processing module determines to perform a secondary determination on the drainage processing method of the garbage.

[0060] The degree of contamination of moisture contained in the collected garbage in the embodiment of the present invention can be determined by the pollutant content of the moisture. The pollutant content of the moisture can be determined by a rapid fluorescence spectrometer through a sampling method. The sampling method can use one percent of the area of ​​the water inlet of a water conservancy and hydropower dam as a sampling point. The leachate treatment method includes expelling the moisture of the garbage with a high degree of contamination through mechanical squeezing and then performing leachate treatment.

[0061] The present invention determines the drainage treatment method for the garbage by analyzing the pollution degree of the water contained in the collected garbage. If the pollution degree of the water contained in the garbage is greater than or equal to the preset pollution degree, the leachate treatment method is selected to treat the garbage for drainage, the water contained in the garbage is squeezed out, and the squeezed water is subjected to leachate treatment to obtain drainable water, thereby avoiding the discharge of highly polluted water and causing the water environment to be polluted. If the pollution degree of the water contained in the garbage is less than the preset pollution degree, the characterization form of the water contained in the garbage is further analyzed to determine the drainage treatment method for the garbage. The above method improves the accuracy of personalized data analysis of the types of garbage, thereby improving the efficiency and quality of garbage cleaning.

[0062] Specifically, the garbage drainage processing module determines the drainage processing method according to the representation form of the water content in the garbage under the condition that the drainage processing method of the garbage is determined to be secondary determined;

[0063] If the representation form of the water content in the garbage is the first representation form, the garbage drainage processing module determines to process the garbage drainage by mechanical squeezing;

[0064] If the representation form of the water content in the garbage is the second representation form, the garbage drainage processing module determines to perform the garbage drainage processing in a flipping and cutting processing manner.

[0065] In the embodiment of the present invention, the first representation form of the moisture contained in the garbage includes moisture contained in the garbage itself, such as a sponge, and the second representation form of the moisture contained in the garbage includes moisture contained in the enclosed space inside the garbage, such as a plastic bottle.

[0066] The present invention further analyzes the characterization form of the moisture contained in the garbage to determine the drainage treatment method for the garbage. If the characterization form of the moisture contained in the garbage is that the garbage itself contains moisture, then a mechanical squeezing treatment method is selected to drain the garbage. If the characterization form of the moisture contained in the garbage is that the enclosed space inside the garbage contains moisture, then a flipping and cutting treatment method is selected to drain the garbage. The above method avoids the phenomenon that the moisture contained in the garbage cannot be discharged due to inaccurate analysis of the garbage drainage treatment process, thereby improving the accuracy of personalized data analysis of the types of garbage.

[0067] Specifically, the garbage classification module classifies the garbage after drainage treatment for processing and records the accuracy of the garbage classification.

[0068] Specifically, the adjustment module determines whether to adjust the parameters of the cleaning process of the water conservancy and hydropower dam water inlet according to the comparison result of the garbage content M detected downstream of the water conservancy and hydropower dam in the period and the preset garbage content M0;

[0069] If M≥M0, the adjustment module determines to adjust the garbage collection speed V by a first adjustment coefficient K1;

[0070] If M<M0, the adjustment module performs a secondary determination to determine whether to adjust the parameters of the water conservancy and hydropower dam water inlet cleaning process;

[0071] Among them, the preset value of the garbage content M0 is 1% of the garbage content at the water inlet of the hydropower dam, but the above value is not limited to this, and technical personnel in this field can also adjust the value according to actual needs.

[0072] The parameters of the water inlet cleaning process of the water conservancy and hydropower dam in the embodiment of the present invention include the garbage collection speed V and the power R of the drainage treatment machine. The period can be set to one tenth of the garbage collection time at the water inlet of the water conservancy and hydropower dam, but the above value is not limited to this. Technical personnel in this field can also adjust the value according to actual needs.

[0073] The present invention determines whether to adjust the parameters of the cleaning process of the water conservancy and hydropower dam water inlet by comparing the garbage content detected downstream of the water conservancy and hydropower dam within a period with the preset garbage content. If the garbage content is greater than or equal to the preset garbage content, it means that the garbage enters the dam water inlet due to the slow speed of collecting garbage at the dam water inlet and flows downstream with the water. At this time, the first adjustment coefficient is selected to increase the garbage collection speed. If the garbage content is less than the preset garbage content, it is necessary to further determine whether to adjust the parameters of the cleaning process of the water conservancy and hydropower dam water inlet according to the accuracy of garbage classification. The above method improves the accuracy of personalized data analysis of garbage types.

[0074] Specifically, the adjustment module determines whether to adjust the parameters of the water conservancy and hydropower dam water inlet cleaning process according to the comparison result of the accuracy G of garbage classification and the preset accuracy G0 under the condition of making a secondary judgment on whether to adjust the parameters of the water conservancy and hydropower dam water inlet cleaning process;

[0075] If G<G0, the adjustment module determines to adjust the power R of the drainage treatment machine by a second adjustment coefficient K2;

[0076] If G≥G0, the adjustment module determines that there is no need to adjust the parameters of the water inlet cleaning process of the hydropower dam.

[0077] The accuracy of garbage classification in the embodiment of the present invention is the ratio of the amount of accurately classified garbage to the total amount of classified garbage. The value range of the preset accuracy G0 is set to 0.8-1, and the value of the preset accuracy G0 is preferably 0.9, but the above value is not limited to this. Technical personnel in this field can also adjust the value according to actual needs.

[0078] Specifically, the first adjustment coefficient K1 is calculated and set by the following formula:

[0079] ;

[0080] The second adjustment coefficient K2 is calculated and set by the following formula:

[0081] ;

[0082] The adjusted garbage collection speed V' is set to V'=K1×V;

[0083] The power R' of the wastewater treatment machine after adjustment is set to R'=K2×R.

[0084] In an embodiment of the present invention, the collection speed can be improved by increasing the number or speed of collection machines during garbage collection. The collection machines include but are not limited to "cleaning boats, cleaning robots and water surface absorbers", and the drainage treatment machines are machines used for garbage drainage treatment, such as filter presses or flip-type cutting presses.

[0085] When further determining whether to adjust the parameters of the water inlet cleaning process of the water conservancy and hydropower dam, the present invention determines that the parameters of the water inlet cleaning process of the water conservancy and hydropower dam need to be adjusted according to the comparison result that the accuracy of garbage classification is less than the preset accuracy. The reason why the accuracy of garbage classification is less than the preset accuracy is that the moisture contained in the garbage cannot be effectively discharged during the drainage treatment of the garbage, resulting in inaccurate judgment of the type of garbage during the garbage classification, resulting in low accuracy of garbage classification. At this time, the second adjustment coefficient is selected to increase the power of the drainage treatment machine to effectively remove the moisture contained in the garbage. The above method is used to improve the accuracy of personalized data analysis of the types of garbage, thereby improving the efficiency and quality of garbage treatment.
