Description

Technical Field

[0001] The present invention relates to the field of concrete transportation, and particularly to an environment-friendly and energy-saving long-distance transportation system for fish ponds. Background Art

[0002] In order to maintain the water quality requirements during fish farming, prevent impurities and germs in the soil from seeping in, keep the water quality clean, and reduce the occurrence of fish diseases, fish ponds are often built with concrete. At the same time, when the terrain is complex, such as in mountainous areas with a lot of rocks, or the geological conditions are poor and the soil's water retention capacity is weak, like sandy soil areas, concrete can be used to shape regular fish pond shapes, effectively preventing water leakage and improving water resource utilization efficiency. Moreover, for modern circulating water aquaculture systems, parameters such as water flow and water quality need to be precisely controlled. The fish ponds with concrete structures have good sealing performance and can better cooperate with equipment such as filtration and aeration to achieve efficient aquaculture. When building large fish ponds, long-distance transportation of concrete is required. Currently, concrete mixtures are generally transported through pipelines. During the transportation process, the water content of the concrete mixture will be severely lost, resulting in condensation and blockage. In addition, the concrete mixture is prone to adhering to the inner wall of the pipeline, which will also cause blockage. Therefore, how to improve the transportation efficiency of concrete pipelines is an urgent problem for those skilled in the art.

[0003] Chinese Patent Publication No. CN118701805A discloses a material conveying device and its operation method for construction projects. The invention discloses a material conveying device and its operation method for construction projects, which relates to the technical field of construction project material conveying and aims to solve the technical problem of the single function of the sand and gravel conveying device during the preparation and transportation of concrete. It includes a processing conveyor; an adjustment mechanism is arranged at the output end of the processing conveyor; the adjustment mechanism is provided with a sand and gravel processing system connected to the support frame of the processing conveyor; a driving mechanism is arranged on the outer side of the sand and gravel processing system; the driving mechanism includes a motor and a synchronous pulley arranged at the output end of the motor; the sand and gravel processing system includes a main body connecting sleeve; a sliding adjustment cavity, a spiral vortex forming cavity, a driving cavity, a planetary cavity, and a processing cavity are sequentially arranged axially inside the main body connecting sleeve. The invention effectively improves the functionality of the material conveying device by two operation modes to adapt to two different types of sand and gravel for concrete prefabrication.

[0004] Chinese Patent Publication No. CN102767184A discloses a concrete pipeline conveying device, including: a conveying pipeline, a chute is provided at the front end of the conveying pipeline, a discharge hopper is provided at the rear end of the conveying pipeline, a spiral blade is provided inside the conveying pipeline, driving devices and connecting flanges are respectively fixedly provided at both ends of the outer part of the conveying pipeline, a bearing air chamber is provided between the driving device and the connecting flange, a shaft seal is provided at the end of the bearing air chamber. The bearing air chamber is a circular pipe wrapped around the outer part of the conveying pipeline, and there is a gap between the circular pipe and the conveying pipeline. The gap space forms an air cushion. The bearing air chamber has an air pressure of 0.2 - 0.6 Mpa, and air holes are provided on the inner side of the inner circle of the circular pipe to communicate the air cushion with the bearing air chamber.

[0005] It can be seen that although the above technical solution discloses a technical solution for conveying concrete using a conveying pipeline, it does not consider the problem of the loss of concrete moisture during the conveying process and the uneven consistency of concrete caused by the temperature difference of concrete, which in turn leads to poor long-distance conveying efficiency of concrete and fails to effectively solve the problem of blockage during the conveying process. Summary of the Invention

[0006] Therefore, the present invention provides an environmentally friendly and energy-saving long-distance transportation system for fish ponds to overcome the problems of the loss of concrete moisture during the concrete conveying process and the uneven consistency of concrete caused by the temperature difference of concrete, and fails to effectively solve the problem of blockage during the conveying process.

[0007] To achieve the above object, the present invention provides an environmentally friendly and energy-saving long-distance transportation system for fish ponds, including:

[0008] A concrete transfer unit for conveying the completed stirred concrete;

[0009] A data acquisition unit connected to the concrete transfer unit for acquiring concrete information and the supply pump delivery pressure. The concrete information includes the concrete flow rate and the concrete flow velocity at the outlet of the conveying pipeline;

[0010] A data analysis unit respectively connected to the concrete transfer unit and the data acquisition unit for determining the concrete flow rate state according to the flow rate reference value and the flow rate fluctuation value, and adjusting the concrete conveying mode under different concrete flow rate states;

[0012] A second adjustment unit respectively connected to the concrete transfer unit, the data acquisition unit and the data analysis unit for determining the fluctuation adjustment mode according to the concrete flow rate fluctuation state;

[0013] Among them, under different said fluctuation adjustment methods, the cooling device is adjusted or the concrete mixing duration is adjusted;

[0014] The corresponding flow reference values and the flow fluctuation values for different said concrete flow states are different.

[0015] Furthermore, the data analysis unit determines the concrete flow state according to the flow reference value and the flow fluctuation value, including:

[0016] The concrete flow reference value is within the first preset flow reference value range and the concrete flow fluctuation value is within the second preset flow fluctuation value range;

[0017] Or, the concrete flow reference value is within the second preset concrete flow reference value range;

[0018] Among them, the first preset flow reference value and the second preset flow reference value are positively correlated with the diameter of the conveying pipeline, the first preset flow reference value is greater than the second preset flow reference value, the first preset flow fluctuation value and the second preset flow fluctuation value are positively correlated with the concrete pipeline conveying rate, the first preset flow fluctuation value is less than the second preset flow fluctuation value, and the concrete flow state includes the first preset concrete flow state and the second preset concrete flow state.

[0019] Furthermore, the data analysis unit determines the fluctuation adjustment method according to the concrete flow fluctuation state under different said concrete flow states, or determines the supply pump delivery pressure adjustment method according to the flow reference value.

[0020] Furthermore, in the second preset concrete flow state, the first adjustment unit increases the supply pump delivery pressure according to the flow reference value;

[0021] The increased value of the supply pump delivery pressure is negatively correlated with the flow reference value.

[0022] Furthermore, the first adjustment unit determines the opening mode of the humidifying nozzle according to the concrete flow response value, or sends a conveying blockage alarm message to the user;

[0023] Among them, the opening mode of the humidifying nozzle includes a uniformly spaced opening mode and a concentrated opening mode.

[0024] Furthermore, the first adjustment unit detects the concrete flow velocity distribution state at the node and determines the opening mode of the humidifying nozzle according to the concrete flow velocity distribution state at the node, including:

[0025] The flow velocity distribution state of the node concrete is in the first preset flow velocity distribution state of the node concrete, and the first adjustment unit determines that the opening mode of the humidification nozzle is the uniform interval opening mode;

[0026] The flow velocity distribution state of the node concrete is in the second preset flow velocity distribution state of the node concrete, and the first adjustment unit determines that the opening mode of the humidification nozzle is the concentrated opening mode;

[0027] Among them, under different opening modes, the distances between adjacent humidification nozzles in the open state are different.

[0028] Furthermore, the second adjustment unit determines the fluctuation adjustment method according to the concrete flow rate fluctuation state, including adjusting the number of cooling layers of the cooling device, adjusting the cooling cycle speed of the cooling device, or adjusting the concrete mixing duration.

[0029] Furthermore, when the second adjustment unit adjusts the number of cooling layers of the cooling device, the number of cooling layers is increased according to the maximum difference in concrete flow rate, and the increase in the number of cooling layers is positively correlated with the maximum difference in concrete flow rate.

[0030] Furthermore, when the second adjustment unit adjusts the cooling cycle speed of the cooling device, the cooling cycle speed is increased according to the maximum difference in concrete flow rate, and the increase in the cooling cycle speed is positively correlated with the maximum difference in concrete flow rate.

[0031] Furthermore, the second adjustment unit increases the concrete mixing duration according to the concrete flow rate peak;

[0032] The increase value of the concrete mixing duration is positively correlated with the concrete flow rate peak within a single monitoring period.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows. In the technical solution of the present invention, the concrete flow rate state is determined according to the flow rate reference value and the flow rate fluctuation value, and the stability of the concrete during the long-distance transportation in the fish pond construction is reflected through the concrete flow rate state. Moreover, different concrete transportation adjustment methods are selected for different concrete flow rate states, so that the selection of the concrete transportation adjustment method is more in line with the actual working scenario, avoiding the deviation of the concrete transportation parameter setting caused by manual setting of working parameters, thereby improving the concrete transportation effect, saving energy, and further improving the long-distance transportation efficiency of the concrete of the present invention.

[0034] Further, in the present invention, the first adjustment unit adjusts the delivery pressure of the supply pump according to the flow reference value, avoiding the situation that the incorrect setting of the delivery pressure of the supply pump leads to the inability of the concrete flow rate to meet the actual working requirements during long-distance transportation. Moreover, taking the flow reference value as the adjustment benchmark, it avoids the problem of poor adjustment accuracy caused by manually regulating the delivery pressure of the supply pump in the prior art, thereby improving the long-distance concrete transportation efficiency of the present invention.

[0035] Further, in the present invention, the first adjustment unit determines the opening mode of the flow humidifying nozzle according to the concrete flow response value. The concrete flow response value reflects whether the adjustment effect of the delivery pressure of the supply pump meets the actual adjustment requirements, and indirectly reflects whether there is a blockage in the concrete corresponding to the concrete transfer unit during long-distance transportation. Then, different opening modes of the flow humidifying nozzle are correspondingly selected, making the opening mode of the flow humidifying nozzle more in line with the actual working scenario, avoiding the problems that the adjustment of the delivery pressure of the supply pump cannot meet the actual working requirements and the delivery pressure of the supply pump is set too high due to blockage during concrete transportation, thereby improving the long-distance concrete transportation efficiency of the present invention.

[0036] Further, in the present invention, the first adjustment unit detects the flow velocity distribution state of the concrete at the node and determines the opening mode of the humidifying nozzle according to the flow velocity distribution state of the concrete at the node. The flow velocity distribution state of the concrete at the node reflects the difference degree of the concrete flow velocity between different transportation positions during concrete transportation. Thus, through the corresponding opening mode of the humidifying nozzle, it can ensure that the moisture in the concrete during transportation can effectively meet the transportation requirements, and at the same time make the opening mode of the humidifying nozzle more targeted, thereby improving the long-distance concrete transportation efficiency of the present invention.

[0037] Further, in the present invention, the second adjustment unit determines the fluctuation adjustment mode according to the concrete flow fluctuation state. The concrete flow fluctuation state reflects the change degree of the concrete flow rate at different times when the concrete flow rate is qualified, and thus effectively characterizes whether the concrete transportation process is stable. Then, different fluctuation adjustment modes are correspondingly selected, so as to ensure the stability of the concrete transportation process by adjusting the cooling device or the concrete mixing duration, thereby improving the long-distance concrete transportation efficiency of the present invention.

[0046] Please refer to Figure 1 As shown, it is the unit connection diagram of the environmentally friendly and energy-saving long-distance transportation system for fish ponds in the embodiments of the present invention. The present invention provides an environmentally friendly and energy-saving long-distance transportation system for fish ponds, including:

[0047] A concrete transfer unit for transporting the mixed concrete;

[0048] A data acquisition unit connected to the concrete transfer unit for collecting concrete information and the supply pump delivery pressure. The concrete information includes the concrete flow rate and the concrete flow velocity at the outlet of the conveying pipeline;

[0049] A data analysis unit, which is respectively connected to the concrete transfer unit and the data acquisition unit, is used to determine the concrete flow state according to the flow reference value and the flow fluctuation value, and to adjust the concrete conveying mode under different concrete flow states. The concrete flow states include a first preset concrete flow state and a second preset concrete flow state;

[0050] A first adjustment unit, which is respectively connected to the concrete transfer unit, the data acquisition unit and the data analysis unit, is used to adjust the conveying pressure of the supply pump according to the flow reference value, and to determine the opening mode of the humidifying nozzle according to the concrete flow response value. The opening modes of the humidifying nozzle include a uniform interval opening mode and a centralized opening mode;

[0051] A second adjustment unit, which is respectively connected to the concrete transfer unit, the data acquisition unit and the data analysis unit, is used to determine the fluctuation adjustment mode according to the concrete flow fluctuation state;

[0052] Among them, under different fluctuation adjustment modes, the cooling device is adjusted or the concrete mixing duration is adjusted;

[0053] The flow reference value and the flow fluctuation value corresponding to different concrete flow states are different.

[0054] Specifically, in the technical solution of the present invention, the concrete flow state is determined according to the flow reference value and the flow fluctuation value, and the stability of the concrete during the long-distance conveying in the fish pond construction is reflected through the concrete flow state. Moreover, different concrete conveying adjustment modes are selected for different concrete flow states, so that the selection of the concrete conveying adjustment mode is more in line with the actual working scenario, avoiding the deviation of the concrete conveying parameter setting caused by manual setting of working parameters, thereby improving the concrete conveying effect, saving energy while further improving the long-distance conveying efficiency of the concrete of the present invention.

[0055] Please refer to Figure 2 as shown, which is a schematic structural diagram of the concrete transfer unit in an embodiment of the present invention. The concrete transfer unit includes:

[0056] A conveying pipeline;

[0057] A screw conveyor, which includes a central rotating shaft 1 arranged inside the conveying pipeline and blades 2 uniformly arranged on the surface of the central rotating shaft, and is used to convey and stir the completed concrete through rotation;

[0058] A plurality of humidifying nozzles 3, which are arranged on the surface of the central rotating shaft 1 and any humidifying nozzle 3 is located between two adjacent blades. Each humidifying nozzle 3 is connected to a water conveying pipeline inside the central rotating shaft 1, and the water conveying pipeline is externally connected to a water supply device;

[0059] A cooling device, which includes a number of cooling layers 4 arranged around the surface of the conveying pipeline. Partition blocks 5 are arranged between the cooling layers 4 for separation, and each cooling layer 4 can achieve independent water supply and drainage, so as to uniformly exchange heat with the concrete inside the conveying pipeline through the circulating cold water inside.

[0060] Please continue to refer to Figure 1 As shown, the data analysis unit determines the concrete flow state according to the flow reference value and the flow fluctuation value, including:

[0061] If the flow reference value is within the first preset flow reference value range and the flow fluctuation value is within the second preset flow fluctuation value range, it is determined as the first preset concrete flow state;

[0062] If the flow reference value is within the second preset flow reference value range, it is determined as the second preset concrete flow state;

[0063] If the flow reference value is within the first preset flow reference value range and the flow fluctuation value is within the first preset flow fluctuation value range, it is determined that the concrete conveying process is qualified;

[0064] Among them, the first preset flow reference value and the second preset flow reference value are positively correlated with the diameter of the conveying pipeline, the first preset flow reference value is greater than the second preset flow reference value, the first preset flow fluctuation value and the second preset flow fluctuation value are positively correlated with the concrete pipeline conveying rate, and the first preset flow fluctuation value is less than the second preset flow fluctuation value.

[0065] Specifically, in the present invention, the first adjustment unit determines the opening mode of the flow humidifying nozzle according to the concrete flow response value. The concrete flow response value reflects whether the adjustment effect of the supply pump delivery pressure meets the actual adjustment requirements, and indirectly reflects whether there is a blockage in the concrete corresponding to the concrete transfer unit during long-distance transportation. Then, different opening modes of the flow humidifying nozzle are correspondingly selected, making the opening mode of the flow humidifying nozzle more in line with the actual working scenario, avoiding the problems that the adjustment of the supply pump delivery pressure cannot meet the actual working requirements and the supply pump delivery pressure is set too large due to blockage during the concrete conveying process, and thus improving the long-distance concrete conveying efficiency of the present invention.

[0066] It can be understood that, under the condition of the same concrete flow velocity, the larger the diameter of the conveying pipeline, the greater the concrete flow rate, so the first preset flow reference value and the second preset flow reference value are greater.

[0067] It can be understood that, under the condition of the same diameter of the concrete conveying pipeline, the greater the concrete pipeline conveying rate, the greater the flow fluctuation value of the concrete due to the frictional resistance between the diameter and the concrete in the pipeline and the bending deformation of the pipeline, so the first preset flow fluctuation value and the second preset flow fluctuation value become larger.

[0068] In implementation, the data acquisition unit is set with a monitoring period. The method for confirming the flow reference value is as follows: for a single monitoring period, the concrete flow at the outlet of the conveying pipeline within 10 s is detected every 30 s, that is, the concrete flow at the outlet of the conveying pipeline is detected once every 40 s. The average value of the concrete flow monitored within a single monitoring period is recorded as the flow reference value. The duration of a single monitoring period can be set by the user according to the actual working scenario. A value for the monitoring period is provided, and the duration of a single monitoring period is 15 min. The calculation formula for the flow fluctuation value S is:

[0069]

[0070] where Si is the concrete flow at the outlet of the conveying pipeline detected for the i-th time within a single monitoring period, S0 is the flow reference value corresponding to this monitoring period, i = 1, 2, 3, ……, n, and n is the total number of times the concrete flow is monitored within a single monitoring period;

[0071] As known to those skilled in the art, the monitoring of the concrete flow at the outlet of the concrete conveying pipeline is a conventional technical means. An operator can use an electromagnetic flowmeter, an ultrasonic flow monitor or the direct weighing method to detect the concrete flow at the outlet of the concrete conveying pipeline. This is a technical means already mastered by those skilled in the art and will not be elaborated here;

[0072] In implementation, the values within the first preset flow reference value range are all greater than the preset flow reference value, and the values within the second preset flow reference value range are all less than or equal to the preset flow reference value. The value of the preset flow reference value can be set by the user according to the actual working scenario. The greater the user's demand for the long-distance concrete conveying efficiency, the greater the preset flow reference value. A method for obtaining the preset flow reference value is provided. The preset flow reference value is Smax×α, where Smax is the maximum allowable concrete flow at the outlet of the conveying pipeline within 10 s, and α is the allowable error coefficient. It can be understood that the determination of the maximum allowable concrete flow can be made by the user according to the diameter of the pipeline, the ambient temperature, the density of the concrete and the humidity of the concrete. The allowable error coefficient reflects the degree of allowable error of the user for the concrete conveying flow in the conveying pipeline. A value for the allowable error coefficient is provided, and α is 0.8; the values within the first preset flow fluctuation value range are all less than 20% of S0, and the values within the second preset flow fluctuation value range are all greater than or equal to 20% of S0.

[0073] Specifically, the data analysis unit determines the concrete conveying adjustment method under different concrete flow states, including:

[0074] In the first preset concrete flow state, the fluctuation adjustment method is determined according to the concrete flow fluctuation state;

[0075] Under the second preset concrete flow state, the supply pump delivery pressure is adjusted according to the flow reference value.

[0076] Specifically, in the present invention, the first adjustment unit adjusts the supply pump delivery pressure according to the flow reference value, avoiding the situation that the incorrect setting of the supply pump delivery pressure leads to the inability of the concrete flow to meet the actual working requirements during long-distance transportation. Moreover, taking the flow reference value as the adjustment benchmark, it avoids the problem of poor adjustment accuracy caused by manual regulation of the supply pump delivery pressure in the prior art, thereby improving the long-distance concrete transportation efficiency of the present invention.

[0077] Specifically, under the second preset concrete flow state, the first adjustment unit increases the adjustment of the supply pump delivery pressure according to the flow reference value;

[0078] The increase value of the supply pump delivery pressure is negatively correlated with the flow reference value.

[0079] Specifically, the first adjustment unit determines the opening mode of the humidifying nozzle according to the concrete flow response value, including determining the opening mode of the humidifying nozzle according to the concrete flow velocity distribution state at the node, or sending a conveying blockage alarm message to the user.

[0080] If the concrete flow response value is less than the first preset concrete flow response value, the first adjustment unit determines that the adjusted concrete flow meets the working requirements and there is no need to select the opening mode of the flow humidifying nozzle;

[0081] If the concrete flow response value is greater than or equal to the first preset concrete flow response value and less than the second preset concrete flow response value, the first adjustment unit determines to determine the opening mode of the humidifying nozzle according to the concrete flow velocity distribution state at the node;

[0082] If the concrete flow response value is greater than or equal to the second preset concrete flow response value, the first adjustment unit determines to send a blockage alarm message to the user.

[0083] Specifically, in the present invention, the first adjustment unit determines the opening mode of the flow humidifying nozzle according to the concrete flow response value. The concrete flow response value reflects whether the adjustment effect of the supply pump delivery pressure meets the actual adjustment requirements, and indirectly reflects whether there is a blockage in the concrete transportation process corresponding to the concrete transfer unit. Then, different opening modes of the flow humidifying nozzle are selected correspondingly, making the opening mode of the flow humidifying nozzle more in line with the actual working scenario, avoiding the problems that the adjustment of the supply pump delivery pressure cannot meet the actual working requirements and the supply pump delivery pressure is set too high due to blockage in the concrete transportation process, thereby improving the long-distance concrete transportation efficiency of the present invention.

[0084] Wherein, the concrete flow response value is the absolute value of the difference obtained by subtracting the preset concrete delivery flow change value from the concrete delivery flow change value obtained after adjusting the delivery pressure of the corresponding supply pump by the first adjustment unit. The concrete delivery flow change value is the difference obtained by subtracting the flow reference value corresponding to a single monitoring period after the adjustment of the supply pump delivery pressure from the flow reference value before the adjustment of the supply pump delivery pressure. For the confirmation method of the preset concrete delivery flow change value, those skilled in the art can obtain a number of concrete delivery flow change values corresponding to different experimental increase ranges of the supply pump delivery pressure of the concrete transfer unit under normal working conditions through experiments or data modeling, which are recorded as alternative preset concrete delivery flow change values. The alternative preset concrete delivery flow change value corresponding to the experimental increase range of the supply pump delivery pressure closest to the increase value of the current supply pump delivery pressure is recorded as the preset concrete delivery flow change value. The first preset concrete flow response value is 10% of the preset concrete delivery flow change value, and the second preset concrete flow response value is 20% of the preset concrete delivery flow change value.

[0085] Specifically, the first adjustment unit detects the concrete flow velocity distribution state at the node and determines the opening mode of the humidification nozzle according to the node concrete flow velocity distribution state, including:

[0086] When the node concrete flow velocity distribution state is in the first preset node concrete flow velocity distribution state, the first adjustment unit determines that the opening mode of the humidification nozzle is the uniform interval opening mode;

[0087] When the node concrete flow velocity distribution state is in the second preset node concrete flow velocity distribution state, the first adjustment unit determines that the opening mode of the humidification nozzle is the concentrated opening mode;

[0088] Wherein, under different opening modes, the distances between adjacent humidification nozzles in the open state are different.

[0089] Specifically, in the present invention, the first adjustment unit detects the node concrete flow velocity distribution state and determines the opening mode of the humidification nozzle according to the node concrete flow velocity distribution state. The difference degree of the concrete flow velocity between different conveying positions during the concrete conveying process is reflected by the node concrete flow velocity distribution state, so that the moisture in the concrete during the conveying process can effectively meet the conveying requirements through the corresponding opening mode of the humidification nozzle, and at the same time, the opening mode of the humidification nozzle is more targeted, thereby improving the long-distance concrete conveying efficiency of the present invention.

[0090] In implementation, the concrete flow velocity distribution state at the first preset node is that the maximum distance between two unqualified flow velocity points is greater than 50% of the length of the conveying pipeline. The concrete flow velocity distribution state at the second preset node is that the maximum distance between two unqualified flow velocity points is less than or equal to 50% of the length of the conveying pipeline. The position of the unqualified flow velocity point is the installation position corresponding to the flow velocity detection device where the detected concrete flow velocity is not within the allowable concrete flow velocity range. The uniform interval opening method is to open a corresponding number of humidifying nozzles, including the humidifying nozzle closest to the concrete input end and the humidifying nozzle closest to the concrete output end. The distance between each adjacent pair of opened humidifying nozzles is the same. The response number has a positive correlation with the number of unqualified flow velocity points, and the maximum value of the response number is the total number of all humidifying nozzles. The centralized opening method is to open all the humidifying nozzles between the two unqualified flow velocity points with the largest distance. The data acquisition unit includes a number of ultrasonic detection devices evenly arranged on the surface of the conveying pipeline, denoted as flow velocity detection devices, for detecting the concrete flow velocity at the corresponding installation position.

[0091] Specifically, the second adjustment unit determines the fluctuation adjustment method according to the concrete flow rate fluctuation state, including adjusting the cooling device under the first concrete flow rate fluctuation state, or adjusting the concrete mixing duration under the second concrete flow rate fluctuation state.

[0092] The concrete flow rate fluctuation state includes:

[0093] The first concrete flow rate fluctuation state, where the flow rate fluctuation value is greater than or equal to 20% of S0 and less than 40% of S0;

[0094] The second concrete flow rate fluctuation state, where the flow rate fluctuation value is greater than or equal to 40% of S0.

[0095] Specifically, in the present invention, the second adjustment unit determines the fluctuation adjustment method according to the concrete flow rate fluctuation state. The concrete flow rate fluctuation state reflects the change degree of the concrete flow rate at different times when the concrete flow rate is qualified, thereby effectively characterizing whether the concrete conveying process is stable, and correspondingly selecting different fluctuation adjustment methods. Thus, by adjusting the cooling device or the concrete mixing duration, the stability of the concrete conveying process is ensured, and further the long-distance concrete conveying efficiency of the present invention is improved.

[0096] Specifically, under the first concrete flow rate fluctuation state, if the number of opened cooling layers of the current cooling device is less than one-half of the total number of cooling layers, when the second adjustment unit adjusts the number of cooling layers of the cooling device, the number of cooling layers is increased according to the maximum difference in concrete flow rate, and the increase amount of the number of cooling layers has a positive correlation with the maximum difference in concrete flow rate;

[0097] Under the condition of the first concrete flow rate fluctuation state, if the number of opened cooling layers of the current cooling device is greater than one-half of the total number of cooling layers, when the second adjustment unit adjusts the cooling cycle speed of the cooling device, the cooling cycle speed is increased according to the maximum difference in concrete flow rate. The increased amount of the cooling cycle speed is positively correlated with the maximum difference in concrete flow rate. The cooling cycle speed is the flow rate of cooling water within a single cooling layer.

[0098] The maximum difference in concrete flow rate is the difference obtained by subtracting the minimum concrete flow rate from the maximum concrete flow rate detected at the outlet of the conveying pipeline within the most recent monitoring period.

[0099] Specifically, the second adjustment unit increases the concrete mixing duration according to the peak value of the concrete flow rate;

[0100] The increased value of the concrete mixing duration is positively correlated with the peak value of the concrete flow rate within a single monitoring period.

[0101] Please refer to Figure 3 As shown in the schematic diagram of the control method for the environmental protection and energy-saving long-distance transportation system for fish ponds in the embodiments of the present invention. The present invention also provides a control method applied to the environmental protection and energy-saving long-distance transportation system for fish ponds, including:

[0102] Step S1, collecting concrete information;

[0103] Step S2, determining the concrete flow rate state according to the flow rate reference value and the flow rate fluctuation value;

[0104] Step S3, determining the concrete conveying adjustment method according to the concrete flow rate state, including determining the fluctuation adjustment method according to the concrete flow rate fluctuation state, or adjusting the conveying pressure of the supply pump according to the flow rate reference value.

[0105] Specifically, in step S3, it includes: Step S31, when the adjustment of the conveying pressure of the supply pump according to the flow rate reference value is completed, determining the opening mode of the flow humidifying nozzle according to the concrete flow rate response value, including determining the opening mode of the humidifying nozzle according to the node concrete flow velocity distribution state, or sending a conveying blockage alarm message to the user;

[0106] Step S32, when determining the fluctuation adjustment method according to the concrete flow rate fluctuation state, adjusting the cooling device, or adjusting the concrete mixing duration.
