[0026] To enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the Figures 1-4 drawings.

[0027] The embodiment of the present utility model provides an intelligent manure backwashing system with a ranch linkage airbag valve, including a flushing module 2 and a drainage module 3 connected to a plurality of manure channels 1. The flushing module 2 and the drainage module 3 are respectively arranged on both sides of the manure channel 1. The other end of the drainage module 3 is connected to a backwashing transfer tank 4, and further includes:

[0028] The control module 5 is used to control the flushing module 2 connected to one or more manure channels 1 to work and flush the corresponding manure channel 1.

[0029] Specifically, for the convenience of manure flow, the manure channel 1 should have a certain slope. Among them, the flushing module 2 is located at the uphill of the manure channel 1, and the drainage module 3 is located at the downhill of the manure channel 1. The flushing module 2 can select multiple common flushing water tanks, and the multiple flushing water tanks correspond to the multiple manure channels 1 one by one. The drainage module 3 can also select common drainage pipes. When it is necessary to backflush and collect the manure in the manure channel 1, the flushing module 2 corresponding to the manure channel 1 works, and a large amount of water is delivered into the corresponding manure channel 1 at one time. The water flushes the manure in the manure channel 1 into the drainage module 3 and flows into the backflush transfer pool 4 along the drainage module 3, completing the backflush collection treatment of the manure in the manure channel 1.

[0030] Obviously, there are often a large amount of undigested forage and solid feed in the manure in the existing manure channels 1 in the ranch. When the flushing module 2 performs backflush treatment on multiple manure channels 1 at the same time, the manure in the multiple manure channels 1 rushes into the drainage pipe at one time, and the forage and undigested solid feed in the manure adhere and accumulate in the drainage pipe, which is very likely to cause the drainage pipe to be blocked, affecting the backflush collection efficiency of the manure in the manure channel 1.

[0031] To solve the above problems, in this embodiment, the control module 5 can select a combination of a remote control terminal and multiple solenoid valves. The multiple solenoid valves correspond to the multiple manure channels 1 one by one. The multiple solenoid valves are all installed on the flushing module 2. Each solenoid valve controls the opening and closing of the drainage end of the flushing water tank connected to the corresponding manure channel 1. Among them, the remote control terminal can remotely control the opening and closing of the solenoid valves. When it is necessary to backflush the manure in the manure channel 1, the remote control terminal controls one or more solenoid valves corresponding to the corresponding manure channel 1 to open, so that the accumulated water in the corresponding flushing water tank is released. The water passes through the manure channel 1 and flushes the manure in the manure channel 1 into the drainage pipe. Because the opening quantity of the solenoid valves can be controlled, it is possible to avoid a large amount of manure rushing into the drainage pipe at one time, and the forage and undigested solid feed in the manure adhere and accumulate in the drainage pipe, resulting in the situation of the drainage pipe being blocked.

[0032] Among them, the opening quantity and opening timing of the solenoid valves controlled by the remote control terminal are both prior arts, and their principles will not be elaborated.

[0033] Preferably, the flushing module 2 includes a pneumatic part 21 and a flushing part 22. The flushing part 22 is used to flush the corresponding manure channel 1, and the pneumatic part 21 controls the flushing timing of the flushing part 22. The pneumatic part 21 includes a wireless control gas supply station 211. A main gas supply pipe 212 is connected to the wireless control gas supply station 211. A plurality of shunt branch pipes 213 are connected to the main gas supply pipe 212. The plurality of shunt branch pipes 213 correspond to the plurality of manure channels 1 one by one. An airbag valve 214 is arranged in the shunt branch pipe 213. The flushing part 22 includes a water supply water pump 221. A main water supply pipe 222 is connected to the water supply water pump 221. A plurality of branch water supply pipes 223 are connected to the main water supply pipe 222. The plurality of branch water supply pipes 223 correspond to the plurality of manure channels 1 one by one. The drainage module 3 includes a plurality of branch drainage pipes 31. The plurality of branch drainage pipes 31 correspond to the plurality of manure channels 1 one by one. One end of the branch drainage pipe 31 is connected to the corresponding manure channel 1. The other ends of the plurality of branch drainage pipes 31 are jointly connected to a main drainage pipe 32. One end of the main drainage pipe 32 is communicated with the backflushing transfer tank 4. The control module 5 includes a backflushing transfer control cabinet 51. The backflushing transfer control cabinet 51 is communicatively connected with the pneumatic part 21.

[0034] Specifically, the plurality of airbag valves 214 correspond to the plurality of branch water supply pipes 223 one by one. The airbag valve 214 is installed in the corresponding branch water supply pipe 223. When the airbag valve 214 is closed, the branch water supply pipe 223 cannot convey water flow to the corresponding manure channel 1. When the airbag valve 214 is opened, the branch water supply pipe 223 conveys water flow to the corresponding manure channel 1 to perform backflushing treatment on the manure channel 1. Moreover, the backflushing transfer control cabinet 51 is composed of a wireless transmission module, a PLC control unit, a display module and a power module. The power module provides power for the wireless transmission module, the PLC control unit and the display module. The power module is a common power supply. The PLC control unit is used to control the working timing of the airbag valve 214. The display module is used to transmit instructions to adjust the programming data of the PLC and change the working timing of the airbag valve 214. The display module selects a common touchable display screen. The wireless transmission module is used to transmit the working command to the wireless control gas supply station 211. The wireless control gas supply station 211 includes an air pump. The air pump is connected to a plurality of airbag valves 214 through a gas distribution valve and a pipeline. When the wireless control gas supply station 211 receives the working command sent by the backflushing transfer control cabinet 51, it sucks out the gas in the airbag valve 214 or conveys gas into the airbag valve 214 through the air pump, so that the airbag valve 214 expands or contracts, realizing the opening or closing action of the airbag valve 214.

[0035] Among them, the steps for backflushing the manure channel 1 are as follows:

[0036] First, the user inputs a control instruction through the backflushing transfer control cabinet 51 to set the sequential opening time instruction of the corresponding airbag valve 214.

[0037] Subsequently, when the airbag valve 214 reaches the opening time, the backflush transfer control cabinet 51 sends an opening signal to the wireless control gas supply station 211. After receiving the opening signal of a certain airbag valve 214, the wireless control gas supply station 211 controls the opening of the airbag valve 214 corresponding to the manure channel 1. Subsequently, the branch water supply pipe 223 is connected to the corresponding manure channel 1, and the branch water supply pipe 223 conveys water flow to the corresponding manure channel 1. The water flow flushes the manure channel 1, and the manure in the manure channel 1 enters the main drainage pipe 32 through the branch drainage pipe 31 connected thereto and flows into the backflush transfer tank 4 along the main drainage pipe 32, completing the backflush treatment of the manure channel 1.

[0038] Obviously, in order to save water resources, except for using clean water for the first flushing of the manure channel 1, afterwards, when backflushing the manure channel 1, the sewage in the backflush transfer tank 4 can be used. That is, the water supply water pump 221 is arranged in the backflush transfer tank 4. The water supply water pump 221 conveys the sewage in the backflush transfer tank 4 into the main water supply pipe 222, and through a plurality of branch water supply pipes 223, a plurality of manure channels 1 are backflushed. At this time, the water flow released by the branch water supply pipe 223 will contain impurities. When the impurities pass through the airbag valve 214, the impurities will rub against the airbag valve 214, which is likely to cause air leakage in the airbag valve 214. At this time, the air pump continuously supplies gas to the airbag valve 214 to keep the airbag valve 214 continuously in the inflated state of gas supply, so that the equipment can still work continuously before maintenance, improving the backflush efficiency of the manure channel 1.

[0039] Preferably, a liquid level control unit 6 is further arranged in the backflush transfer tank 4. The liquid level control unit 6 is used to detect the liquid level height in the backflush transfer tank 4. The liquid level control unit 6 includes an extreme liquid level controller 61, a high liquid level controller 62 and a low liquid level controller 63. The extreme liquid level controller 61, the high liquid level controller 62 and the low liquid level controller 63 are installed in the backflush transfer tank 4 along the vertical direction. A transfer component 7 is further arranged in the backflush transfer tank 4. When the manure and sewage mixture in the backflush transfer tank 4 reaches the detection height of the high liquid level controller 62, the high liquid level controller 62 sends an electrical signal to the transfer component 7, and the transfer component 7 transfers the manure and sewage mixture in the backflush transfer tank 4.

[0040] Specifically, in this embodiment, the extreme liquid level controller 61, the high liquid level controller 62 and the low liquid level controller 63 are all selected as sensors. The transfer component 7 can be selected as a combination of a transfer pump and a transfer pipeline. The transfer pump is located inside the backflush transfer tank 4, and the transfer pipeline is connected to the transfer pump.

[0041] As the fecal sewage in each sewage channel 1 is flushed and conveyed into the backflush transfer tank 4, the liquid level of the backflush transfer tank 4 will rise. When the liquid level height of the backflush transfer tank 4 reaches the set high liquid level, the high liquid level controller 62 detects the liquid level signal, and the high liquid level controller 62 sends a signal to the transfer pump. The transfer pump works, sucking out the fecal sewage mixture in the backflush transfer tank 4 and transferring the fecal sewage mixture in the backflush transfer tank 4 to the fecal sewage treatment area through the transfer pipeline for treatment. As the transfer pump works, the liquid level height in the backflush transfer tank 4 begins to drop. When the liquid level height is lower than the low liquid level controller 63, the low liquid level controller 63 sends a signal to the transfer pump, and the transfer pump stops transferring the fecal sewage mixture in the backflush transfer tank 4.

[0042] It should be noted that in this embodiment, the minimum liquid level of the liquid in the backflush transfer tank 4 should meet the water volume required for the water supply water pump 221 to flush all the sewage channels 1 at one time. And when the liquid level height in the backflush transfer tank 4 reaches the monitoring range of the limit liquid level controller 61, the backflush transfer control cabinet 51 stops working and performs an alarm process to notify the staff to clean the backflush transfer tank 4.

[0043] Obviously, if the high liquid level controller 62 fails, the fecal sewage will continue to enter the backflush transfer tank 4. Among them, the entry of fecal sewage into the backflush transfer tank 4 is a phased continuous process. That is, when the fecal sewage enters the inside of the backflush transfer tank 4, the liquid level height in the backflush transfer tank 4 will continue to increase. If the limit liquid level controller 61 monitors that the liquid level reaches the maximum liquid level when the liquid level starts to increase, and terminates the subsequent backflush process in time, but this round of backflush operation has been completed, and the fecal sewage generated by the backflush will still enter the backflush transfer tank 4. If the backflush transfer tank 4 cannot accommodate the remaining fecal sewage, the fecal sewage will overflow from the branch drainage pipe 31, affecting the environment of the ranch.

[0044] To solve the above problems, in another embodiment of the present utility model, an expansion component 8 is further provided on the backflush transfer tank 4, and the expansion component 8 is used to increase the volume of the backflush transfer tank (4).

[0045] Specifically, in this embodiment, the backflush transfer tank 4 includes a tank body 41 and a tank cover 42. Among them, the expansion component 8 includes a corrugated pipe 81. The cross-sectional shape of the corrugated pipe 81 is the same as the cross-sectional shape of the backflush transfer tank 4. The corrugated pipe 81 connects the tank body 41 and the tank cover 42, and the tank body 41 and the tank cover 42 are connected by an elastic member 82. The elastic member 82 can be selected as a spring, and the elastic member 82 is used to assist the corrugated pipe 81 after stretching to return to its original state.

[0046] When an excessive amount of manure is discharged into the flushing transfer tank 4, the manure in the flushing transfer tank 4 continuously increases and squeezes the tank cover 42, driving the tank cover 42 to move vertically away from the tank body 41. At this time, the corrugated pipe 81 and the elastic member 82 are stretched. The stretched elastic member 82 accumulates elastic potential energy. The stretched corrugated pipe 81 is equivalent to increasing the height of the tank body 41, enabling the flushing transfer tank 4 to accommodate more manure and preventing excessive manure from overflowing from the branch drain pipe 31, thus avoiding the situation of affecting the environment of the ranch. When the corrugated pipe 81 is stretched, the device starts to alarm, reminding the staff to repair the flushing transfer tank 4. When the amount of manure in the flushing transfer tank 4 decreases, the elastic member 82 releases the accumulated elastic potential energy, driving the tank cover 42 to move vertically towards the tank body 41. Under the extrusion of the tank cover 42, the corrugated pipe 81 resets.

[0047] Obviously, due to the presence of solid waste in the manure in the flushing transfer tank 4, when the solid waste rubs against the inner wall of the corrugated pipe 81, the corrugated pipe 81 is easily scratched by the solid waste, resulting in damage to the corrugated pipe 81. The manure in the flushing transfer tank 4 will overflow to the outside of the flushing transfer tank 4 from the damaged position of the corrugated pipe 81, affecting the environment.

[0048] To solve this problem, in this embodiment, preferably, the corrugated pipe 81 is provided with two layers. The two corrugated pipes 81 are arranged in concentric circles, and there is a cavity 83 between the two corrugated pipes 81. The elastic member 82 is arranged in the cavity 83.

[0049] Specifically, when the corrugated pipe 81 is provided with two layers, even if the inner corrugated pipe 81 is damaged by the garbage in the manure and the manure overflows from the damaged area of the inner corrugated pipe 81, the overflowed manure accumulates in the cavity 83 between the two corrugated pipes 81. At this time, the outer corrugated pipe 81 continues to play a protective role, preventing the manure from overflowing from the flushing transfer tank 4. At this time, the inner corrugated pipe 81 can have a filtering effect, preventing large solid waste in the flushing transfer tank 4 from entering the cavity 83 and avoiding the situation where the outer corrugated pipe 81 is scratched by large solid waste.

[0050] It should be noted that when there is enough space inside the backflush transfer tank 4, the fecal sewage located in the cavity 83 needs to return to the backflush transfer tank 4. Furthermore, a liquid discharge channel 84 is provided on the tank body 41. The liquid discharge channel 84 connects the cavity 83 with the internal space of the backflush transfer tank 4. A check valve is provided in the liquid discharge channel 84. The check valve is used to allow the fecal sewage in the cavity 83 to enter the backflush transfer tank 4 through the liquid discharge channel 84 and prevent the fecal sewage in the backflush transfer tank 4 from entering the cavity 83 through the liquid discharge channel 84. Moreover, the opening and closing power of the check valve can be realized according to the pressure exerted by the fecal sewage in the cavity 83 on the check valve when the corrugated pipe 81 resets. That is, when the corrugated pipe 81 resets, the volume of the cavity 83 between the two corrugated pipes 81 becomes smaller, thereby compressing the fecal sewage in the cavity 83 and increasing the pressure exerted by the fecal sewage on the check valve to drive the check valve to open.

[0051] Only some exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
