[0002] The breeding industry often suffers huge losses due to epidemics, especially African swine fever, which has the greatest impact on the pig breeding industry.

[0003] Vehicles that transport animals or animal meat products in batches have a wide range of activities and areas. When a vehicle is contaminated with viruses and enters a farm or the vicinity of a farm, it will directly or indirectly spread the virus to the farm. The biosafety risk of the vehicle carrying the virus to the breeding industry is very large, so vehicles entering farms, feed processing plants, and slaughterhouses will be non-contact washed and sprayed with disinfectants to reduce the risk of vehicles carrying and spreading viruses. At present, most of the industry completes the cleaning and disinfection operations by manually preparing cleaning foam and disinfectant, and manually using a car washing machine to spray cleaning foam, water washing, and spraying disinfectant water on the transport vehicles.

DETAILED DESCRIPTION

[0052] 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.

[0053] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] like Figure 1 As shown, the cleaning and disinfection module provided by the present invention includes a supporting guide rail and a movable beam mechanism that can move along the supporting guide rail, a pair of side disinfection mechanisms 107 are arranged on both sides below the movable beam mechanism, and the side disinfection mechanisms 107 are used to clean and disinfect the two sides of the vehicle; a lifting and flipping disinfection mechanism 108 that can be lifted and flipped is connected between the pair of side disinfection mechanisms 107, and the front and rear surfaces of the vehicle are lifted and disinfected by means of the lifting and flipping disinfection mechanism 108, and the top of the vehicle can be flipped / rotated 90° to disinfect; during the disinfection process, the first swinging component of the side disinfection mechanism 107 can drive its nozzle component to swing up and down, and the second swinging component of the lifting and flipping disinfection mechanism 108 can drive its nozzle component to swing left and right, thereby minimizing the blind angle of disinfection and improving the disinfection effect.

[0055] The support rails are set up as follows Figure 1As shown, the support rail includes two rows of columns 101 arranged at a preset interval and a pair of I-beam rails 104 respectively connected to the top of the two rows of columns 101. A transverse support 102 is arranged on the top of the column 101, and the I-beam rail 104 is mounted on the transverse support 102. In order to improve the reliability of the support, an oblique support 103 obliquely connecting the transverse support 102 and the column 101 is also arranged at the bottom of the transverse support 102. The oblique support 103 is preferably arranged at an inclination of 45°.

[0056] The movable crossbeam mechanism includes a crossbeam body 106 and a walking mechanism 105 connected to both ends of the crossbeam body 106 and used to cooperate with the I-beam guide rail 104 to drive the crossbeam body 106 to move. Figure 1 and Figure 2 As shown, the arrangement of the walking mechanism 105 is as follows Figures 11 to 13 The walking mechanism 105 includes a walking frame 138 connected to the crossbeam mechanism, a walking motor 139 and a reducer 140 are installed in the middle of the walking frame 138, and walking wheel assemblies are arranged at the bottom of both sides of the walking frame 138. The reducer 140 is connected to the walking wheel assembly through a rotating shaft and a chain sprocket, and the reciprocating motion relative to the I-beam guide rail 104 is realized by the forward rotation and flipping of the walking motor 139. In order to improve the stability of the movement of the walking mechanism 105 relative to the guide rail, guide wheels 137 are arranged on both sides of the bottom of the walking frame 138, and the I-beam guide rail 104 is clamped along the width direction of the upper flange of the I-beam guide rail 104 by the guide wheels 137, so as to provide a guiding effect for the movement of the walking mechanism 105.

[0057] The walking wheel assembly includes a mounting bracket 141 and a walking wheel body 142 arranged in the mounting bracket 141. The walking wheel body 142 is usually a rubber-coated wheel; further, an anti-rollover wheel 143 is arranged at the bottom of the mounting bracket 141, and the anti-rollover wheel 143 is arranged on a single side below the walking wheel body 142. By cooperating with the walking wheel body 142 to clamp the upper flange of the I-beam guide rail 104 up and down, the walking stability is improved.

[0058] As a preferred embodiment, a vehicle arrival detection mechanism can be set on the side of the crossbeam body 106 or the column 101, and the vehicle arrival detection mechanism can be a photoelectric switch; in order to avoid misjudgment of the vehicle arrival detection mechanism due to different vehicle heights or vehicle body gaps, the vehicle arrival detection mechanism can usually be set below the crossbeam body 106 and centered relative to the crossbeam body 106. Limiting pieces are respectively set at corresponding positions in the length direction of the I-beam guide rail 104, and a travel switch 144 is set at the bottom of the walking mechanism 105. The cooperation between the travel switch 144 and the limiting piece drives the moving crossbeam mechanism to reciprocate along the I-beam guide rail 104. The limiting piece can be fixed at different positions of the I-beam guide rail 104 as needed, and the travel switch 144 is specifically installed at the bottom of the walking frame 138 or the mounting bracket 141.

[0059] Please refer to Figures 2 to 4 The assembly relationship of the side disinfection mechanism 107, the lifting and flipping disinfection mechanism 108 and the beam body 106 is as follows: the side disinfection mechanism 107 includes a side frame 136, and the lifting and flipping disinfection mechanism 108 includes a flipping frame 115. A pair of side frames 136 of the side disinfection mechanism 107 are arranged oppositely and vertically fixed to the bottom of the beam body 106. The inner sides of the side frames 136 are arranged oppositely and provided with guide rails and lifting sliders 112. Both ends of the flipping frame 115 are fixed to the lifting sliders 112. A worm motor 109 and a transmission shaft 110 are arranged at the top of the beam body 106. The transmission shaft 110 is supported and fixed by a bearing seat 111. The worm motor 109 is arranged centrally relative to the beam body 106 and is connected to the transmission shaft 110 through gear transmission. Gears are set at both ends of the transmission shaft 110, and gears are set at the bottom of the side frame 136. The gears of the transmission shaft 110 and the gears at the bottom of the side frame 136 are connected by chain transmission. The lifting slider 112 is mounted on one side of the chain and is lifted and lowered under the drive of the worm motor 109.

[0060] like Figures 8 to 10 As shown, the side cleaning mechanism 107 also includes a side foam spray bar 145, a side cleaning spray bar 146 and a side disinfection spray bar 147, and the nozzle assembly connected to the side cleaning mechanism 107 specifically includes a foam nozzle 129 connected to the side foam spray bar 145, a disinfection nozzle 127 connected to the side disinfection spray bar 147 and a cleaning nozzle 128 connected to the side cleaning spray bar 146. The side foam spray bar 145 and the side disinfection spray bar 147 are respectively fixed on both sides of the side frame 136, and the side cleaning spray bar 146 is arranged between the side foam spray bar 145 and the side disinfection spray bar 147. The three are generally arranged parallel to each other in the vertical direction, and the specific position can be adjusted as needed.

[0061] A mounting hole is provided on the side cleaning spray rod 146, and a first swivel joint 135 is provided in the mounting hole. The first swivel head is connected to the first nozzle mounting member 134, and the cleaning nozzle 128 is mounted on the first nozzle mounting member 134. The first swing assembly includes a first motor 130 and a first pull rod 133 mounted on the side frame 136. One end of the first pull rod 133 is hinged to the side frame 136 through a connecting rod, and the other end is connected to the first motor 130 through a first crankshaft connecting rod assembly. The first crankshaft connecting rod assembly includes a first crankshaft 131 and a first connecting rod 132. The first crankshaft 131 is connected to the output shaft of the first motor 130. The two ends of the first connecting rod 132 are respectively connected to the first crankshaft 131 and the first pull rod 133. The first pull rod 133 has a first slotted hole, and the cleaning nozzle 128 and the first nozzle mounting member 134 are arranged through the first slotted hole. When the first motor 130 rotates, the first pull rod 133 is driven to swing up and down through the first crankshaft connecting rod assembly, thereby adjusting the cleaning nozzle 128 to swing up and down to spray water.

[0062] In a specific implementation, the side foam spray rod 145 and the side disinfection spray rod 147 can not only be fixed on both sides of the side frame 136 respectively, but also be fixedly connected to the first pull rod 133 through a laterally arranged connecting rod. When the first motor 130 drives the first pull rod 133 and the cleaning nozzle 128 to swing up and down, the side foam spray rod 145 and the foam nozzle 129, and the side disinfection spray rod 147 and the disinfection nozzle 127 swing up and down synchronously, so as to perform uniform and full coverage cleaning and disinfection on both sides of the vehicle.

[0063] like Figures 5 to 7 As shown, the lifting and flipping decontamination mechanism 108 also includes a foam spray rod 125, a cleaning spray rod 122 and a disinfection spray rod 126. The nozzle assembly connected to the lifting and flipping decontamination mechanism 108 specifically includes a foam nozzle 129 connected to the foam spray rod 125, a disinfection nozzle 127 connected to the disinfection spray rod 126 and a cleaning nozzle 128 connected to the cleaning spray rod 122. The foam spray rod 125 and the disinfection spray rod 126 are respectively fixed on both sides of the flip frame 115, and the cleaning spray rod 122 is arranged between the foam spray rod 125 and the disinfection spray rod 126. The three are generally arranged parallel to each other in the horizontal direction, and the specific position can be adjusted as needed.

[0064] A mounting hole is provided on the cleaning spray rod 122, and a second rotary joint 121 is provided in the mounting hole. The second rotary head is connected to the second nozzle mounting member 120, and the cleaning nozzle 128 is installed on the second nozzle mounting member 120. The second swing assembly includes a second motor 116 and a second pull rod 119 installed on the flip frame 115. One end of the second pull rod 119 is hinged to the flip frame 115 through a connecting rod, and the other end is connected to the second motor 116 through a second crankshaft connecting rod assembly. The second crankshaft connecting rod assembly includes a second crankshaft 117 and a second connecting rod 118. The second crankshaft 117 is connected to the output shaft of the second motor 116. The two ends of the second connecting rod 118 are respectively connected to the second crankshaft 117 and the second pull rod 119. The second pull rod 119 has a second slot, and the cleaning nozzle 128 and the second nozzle mounting member 120 are arranged through the second slot. When the second motor 116 rotates, the second pull rod 119 is driven to swing left and right through the second crankshaft connecting rod assembly, thereby adjusting the cleaning nozzle 128 to swing left and right to spray water.

[0065] In specific implementation, the foam spray rod 125 and the disinfection spray rod 126 can not only be fixed on both sides of the flip frame 115 respectively, but also be fixedly connected to the second pull rod 119 through a laterally arranged connecting rod. When the second motor 116 drives the second pull rod 119 and the cleaning nozzle 128 to swing left and right, the foam spray rod 125 and the foam nozzle 129, the disinfection spray rod 126 and the disinfection nozzle 127 swing left and right synchronously, so as to clean and disinfect the top, front and rear of the vehicle evenly and fully.

[0066] When the lifting and flipping cleaning mechanism 108 is cleaning the rear of the vehicle, the nozzle assembly of the lifting and flipping cleaning mechanism 108 is facing the rear of the vehicle, and is lifted and sprayed under the drive of the worm motor 109 and the lifting slider 112; while lifting and spraying, the second motor 116 drives the second pull rod 119 and the cleaning nozzle 128 to swing left and right through the second crankshaft connecting rod assembly. After completing the cleaning operation of the rear of the vehicle, the flip frame 115 rotates 90° so that all the nozzle assemblies on the lifting and flipping cleaning mechanism 108 are facing the roof; the walking mechanism 105 drives the crossbeam body 106, the side cleaning mechanism 107 and the lifting and flipping cleaning mechanism 108 to move along the I-beam guide rail 104 to achieve spraying, and the worm motor 109 is no longer running. When the roof cleaning operation is completed, the flip frame 115 flips again to a preset angle such as 90° or 45°, and the specific flip angle is flexibly set according to the shape of the front of the vehicle.

[0067] The flip function of the flip frame 115 can be realized by referring to Figure 3 ,and Figures 5 to 7, a flip plate 113 is arranged at both ends of the flip frame 115, and a flip motor 123 is fixedly arranged inside the flip frame 115; the flip plate 113 is fixedly connected to the lifting slider 112, and the flip plate 113 has a shaft perpendicular to its plate surface, and the output shaft of the flip motor 123 is connected to the shaft of the flip plate 113 through a coupling 124, and the end of the flip frame 115 is fixedly connected to a flanged bearing 114 through which the shaft is provided. When the flip frame 115 needs to flip, the flip motor 123 is operated, and since the output shaft of the flip motor 123 is fixedly connected to the shaft of the flip plate 113, the flip plate 113 is fixedly connected to the lifting slider 112, and the flip plate 113, that is, the output shaft of the flip motor 123, does not rotate, so that the housing of the flip motor 123 drives the flip frame 115 to rotate a set angle.

[0068] The cleaning and disinfection module provided by the present invention further includes a control mechanism and a vehicle appearance acquisition mechanism. The control mechanism can adopt a single chip microcomputer, etc., the vehicle appearance acquisition mechanism can adopt a laser radar or a camera module, and the above-mentioned limiter can specifically adopt a limiter trolley. The flip motor 123, the first motor 130, the second motor 116, the worm motor 109, the travel motor 139, the limiter trolley, the travel switch 144, the vehicle arrival detection mechanism and the vehicle appearance acquisition mechanism are all connected to the control mechanism.

[0069] The specific working principle is as follows: the vehicle enters the disinfection position, the vehicle arrival detection mechanism detects the vehicle arrival information and transmits it to the control mechanism, the control mechanism controls the vehicle appearance acquisition mechanism to obtain the vehicle's appearance size information, and then controls the limit trolley on the I-beam guide rail 104 to move to the two ends of the length direction of the vehicle to be disinfected for limiting according to the vehicle's appearance size information, and successively controls the side disinfection mechanism 107 and the lifting and flipping disinfection mechanism 108 to clean each side of the vehicle according to the limiter and the travel switch 144. During the disinfection of the front and rear of the vehicle, the control mechanism is also used to control the flip motor 123 to rotate to a set angle according to the front and rear shapes obtained by the vehicle appearance acquisition mechanism, to ensure that the nozzle assembly of the lifting and flipping disinfection mechanism 108 is perpendicular to the front and rear surfaces of the vehicle or always maintains a set cleaning angle with the front and rear surfaces of the vehicle, thereby improving the disinfection effect.

[0070] In a preferred embodiment provided in the present application, the cleaning and disinfection module further comprises a vehicle bottom cleaning and disinfection mechanism for washing and disinfecting the bottom of the vehicle, and the vehicle bottom cleaning and disinfection mechanism comprises a cleaning trolley 201 and a vehicle bottom nozzle assembly arranged on the cleaning trolley 201. Fig.14 and Fig.15, the side of the cleaning trolley 201 is provided with a traveling wheel 205, the bottom is provided with a guide wheel 206, and the top is arranged from one end of the vehicle body to the other end in sequence with a vehicle bottom foam spray rod 202, a vehicle bottom cleaning spray rod 203 and a vehicle bottom disinfection spray rod 204, and the vehicle bottom nozzle assembly includes a vehicle bottom foam nozzle 215 installed on the vehicle bottom foam spray rod 202, a vehicle bottom cleaning nozzle 216 installed on the vehicle bottom cleaning spray rod 203 and a vehicle bottom disinfection nozzle 217 installed on the vehicle bottom disinfection spray rod 204. The vehicle bottom foam nozzle 215 can be a duckbill nozzle, the vehicle bottom cleaning spray rod 203 is connected to the cleaning trolley 201 through the vehicle bottom rotating joint 207, and the vehicle bottom cleaning nozzle 216 is arranged at an angle to facilitate rotation during the cleaning process to improve the cleaning effect, and the vehicle bottom disinfection nozzle 217 usually uses a universal nozzle.

[0071] The foam spray bar 125, the side foam spray bar 145 and the bottom foam spray bar 202 are connected to the foam preparation module through hoses; the disinfection spray bar 126, the side disinfection spray bar 147 and the bottom disinfection spray bar 204 are connected to the automatic dispensing module through hoses; the cleaning spray bar 122, the side cleaning spray bar 146 and the bottom cleaning spray bar 203 are all connected to the clean water module through hoses. The function of the clean water module is to provide clean water to the cleaning and disinfection module, which can be a water tower, a water storage tank or even a tap water pipe.

[0072] The cleaning trolley 201 can be equipped with its own driving mechanism, but considering that foam, clean water and disinfectant will fall back to the cleaning trolley 201 during the cleaning process, the cleaning trolley 201 of the present application is driven by external traction. At this time, traction rings are set at both ends of the first head of the cleaning trolley 201, and the bottom cleaning mechanism also includes a traction motor 209, a driving wheel 212, a driven wheel 213 and a flexible traction part 214 wound around the driving wheel 212 and the driven wheel 213. The flexible traction part 214 is preferably made of steel wire rope, and the two ends of the steel wire rope are respectively connected to the traction ring 208 to form a rotating closed-loop structure along the driving wheel 212 and the driven wheel 213.

[0073] Furthermore, it also includes a front limit 210 and a rear limit 211 set at a preset position on the ground. During the disinfection operation, the vehicle to be disinfected enters between the front limit 210 and the rear limit 211. When the cleaning trolley 201 touches the front limit 210 or the rear limit 211, the traction motor 209 flips, thereby ensuring that the cleaning trolley 201 moves between the front limit 210 and the rear limit 211. The front limit 210 and the rear limit 211 can be fixed, or the position can be adjusted manually. The position setting of the limit piece on the I-beam guide rail 104 can also be referred to. The control mechanism adjusts the specific position of the front limit 210 and the rear limit 211 according to the size information of the vehicle detected by the vehicle appearance acquisition mechanism.

[0074] Please refer to Fig.16The automatic dispensing module provided by the present invention includes a clean water pipeline 301, a disinfectant pipeline 318 for outputting disinfectant, and a proportioning and mixing mechanism arranged between the clean water pipeline 301 and the disinfectant pipeline 318. The clean water pipeline 301 is also connected to the disinfectant stock solution preparation mechanism. The disinfectant stock solution preparation mechanism at least includes a stock solution barrel 303, and a stirring mechanism can be arranged in the stock solution barrel 303 as needed. With the help of the stirring mechanism, the powdered disinfectant is uniformly dissolved in the clean water to form a concentrated solution / disinfectant stock solution, which reduces the preparation risk and work intensity, and helps to improve the accuracy of subsequent proportioning.

[0075] When preparing the disinfectant, it is only necessary to add a quantitative amount of powdered disinfectant into the stock liquid barrel 303, keep the first control valve 302 open, and use the clean water pipe 301 to transport clean water into the stock liquid barrel 303 to mix and obtain a concentrated liquid. After the second control valve 304 is opened, the stock liquid pump 305 transports the concentrated liquid to the proportioning and mixing mechanism, and the proportioning and mixing mechanism mixes the clean water and the concentrated liquid in proportion to obtain a diluted disinfectant, thereby realizing the preparation of disinfectant with powdered disinfectant and reducing the preparation cost of the disinfectant.

[0076] In addition, the first control valve 302 can be kept closed, and the stock liquid barrel 303 is filled with disinfectant stock liquid, and the disinfectant stock liquid is input into the proportioning and mixing mechanism and mixed with clean water in proportion, so as to prepare the disinfectant liquid with the liquid disinfectant stock liquid.

[0077] In the specific embodiment provided by the present invention, the proportioning and mixing mechanisms are arranged in parallel in multiple groups. Fig.16 The working principle is described by taking two groups as examples. The proportioning and mixing mechanism includes a proportioning barrel 308 and a liquid level detection mechanism arranged in the proportioning barrel 308. A fourth control valve 307 is arranged between the proportioning barrel 308 and the clean water pipeline 301, and a fifth control valve 309 is arranged between the proportioning barrel 308 and the disinfectant pipeline 318. The second control valve 304 is specifically arranged between the stock liquid barrel 303 and the stock liquid pump 305, and a third control valve 306 is arranged between the stock liquid pump 305 and the proportioning barrel 308 of any group of proportioning and mixing mechanisms.

[0078] When the powdered disinfectant is prepared to form a concentrated liquid, the first control valve 302 is closed, the second control valve 304 is opened, the third control valve 306 of one group of proportioning and mixing mechanisms is opened, and the stock liquid pump 305 quantitatively delivers the disinfectant stock liquid to the proportioning barrel 308. After that, the third control valve 306 connected to the group of proportioning barrels 308 is closed, the fourth control valve 307 is opened, and clean water is added to the proportioning barrel 308. After the liquid level detection mechanism detects that the mixed liquid reaches the set liquid level, the fourth control valve 307 is closed, the disinfectant stock liquid and clean water are mixed to form a disinfectant of a preset concentration, and the fifth control valve 309 is opened to output the disinfectant to the disinfectant pipeline 318; when the liquid level detection mechanism detects that the liquid level in the proportioning barrel 308 drops to another set height, the fifth control valve 309 is closed.

[0079] While one group of proportioning and mixing mechanisms outputs disinfectant, the third control valve 306 connected to another group of proportioning and mixing mechanisms is opened, and the raw liquid pump 305 delivers disinfectant raw liquid / concentrated liquid to the group of proportioning barrels 308. Then the third control valve 306 is closed, the fourth control valve 307 is opened, and clean water is added to the proportioning barrel 308. After the liquid level detection mechanism detects that the mixed liquid reaches the set liquid level, the fourth control valve 307 is closed, the disinfectant raw liquid and clean water are mixed to form a disinfectant of a preset concentration, and the fifth control valve 309 is opened to output disinfectant to the disinfectant pipeline 318; when the liquid level detection mechanism detects that the liquid level in the proportioning barrel 308 drops to another set height, the fifth control valve 309 is closed.

[0080] In this way, the stock liquid pump 305 alternately delivers the disinfectant stock liquid / concentrated liquid prepared by the powdered disinfectant to different groups of proportioning and mixing mechanisms, ensuring that there is always a continuous output of disinfectant.

[0081] In the above embodiment, the liquid level detection mechanism provided in the proportioning barrel 308 specifically includes an upper liquid level sensor 310 set at a set height above the proportioning barrel 308 and a lower liquid level sensor 311 set at a set height below the proportioning barrel 308. When the liquid level in the proportioning barrel 308 filled with clean water reaches the upper liquid level sensor 310 and is detected, the fourth control valve 307 is closed; when the liquid level drops to the lower liquid level sensor 311 when the disinfectant is output and is detected, the fifth control valve 309 is closed, and the lower liquid level sensor 311 can be specifically provided at the bottom of the proportioning barrel 308.

[0082] Furthermore, a stirring mechanism may be provided in the proportioning barrel 308 as required. Specifically, the stirring mechanism may be a paddle stirring mechanism provided at the bottom of the barrel or a pneumatic stirring mechanism connected to the proportioning barrel 308 .

[0083] Preferably, the stock liquid barrel 303 used to dissolve the powdered disinfectant is also provided with a third liquid level detection mechanism, and the setting of the third liquid level detection mechanism can refer to the liquid level detection mechanism of the proportioning barrel 308. After the powdered disinfectant is quantitatively added, the first control valve 302 is closed when clean water is added to the set upper liquid level sensor 310, and when the disinfectant stock solution / concentrate is continuously output and the liquid level drops to the set lower liquid level sensor 311, the second control valve 304 is closed, and the powdered disinfectant needs to be added again to prepare the disinfectant stock solution.

[0084] To optimize the above embodiment, the automatic dispensing module provided by the present application also includes an automatic proportional pump 313 and a buffer barrel 315 connected between the clean water pipeline 301 and the disinfectant pipeline 318. Among them, the automatic proportional pump 313 is used to suck the clean water in the clean water pipeline 301 and the disinfectant stock solution contained in the mother liquid barrel 314 according to the set ratio and mix them to the buffer barrel 315, and then the buffer barrel 315 is sent to the disinfectant pipeline 318. A sixth control valve 312 is set between the automatic proportional pump 313 and the clean water pipeline 301, and a seventh control valve 316 is set between the buffer barrel 315 and the disinfectant pipeline 318. The automatic proportional pump 313, the buffer barrel 315 and the mother liquid barrel 314 are used to prepare the disinfectant with the disinfectant stock solution and clean water, so that the proportioning and mixing mechanism is only used to prepare the disinfectant using the powdered disinfectant without interfering with each other.

[0085] The mother liquid barrel 314 may be provided with a lower liquid level sensor 311, and a second liquid level detection mechanism may be provided in the buffer barrel 315. The second liquid level detection mechanism may be provided with an upper liquid level sensor 310 and a lower liquid level sensor 311, or may be a liquid level gauge provided along the height direction of the buffer barrel 315, for continuously detecting the liquid level. When the liquid level drops to a set position such as the lower liquid level sensor 311, the seventh control valve 316 is closed, the sixth control valve 312 and the automatic proportional pump 313 are opened, and the disinfectant is reconfigured.

[0086] When the buffer barrel 315 outputs disinfectant, in order to prevent the disinfectant from flowing back into the confluence pipeline of the multiple proportioning and mixing mechanisms, a confluence control valve 317 is provided in the confluence pipeline.

[0087] The automatic dispensing module further includes a dry powder conveying mechanism, which is used to quantitatively (massively) convey powdered disinfectant into the stock liquid barrel 303. The control mechanism is connected to all control valves, dry powder conveying mechanisms, and all liquid level detection mechanisms of the automatic dispensing module, so as to control the corresponding control valves to open or close according to the set program control and the corresponding liquid level detection results, and control the dry powder conveying mechanism to convey powdered disinfectant, thereby improving the efficiency of disinfectant preparation and reducing the labor intensity of staff. The dry powder conveying mechanism can be set with reference to the existing technology.

The air circuit mechanism is used to provide pressurized gas to the venturi gas-liquid mixer 420, and the water circuit mechanism is used to transport the foaming agent mixed liquid to the venturi gas-liquid mixer 420. The pressurized gas and the foaming agent mixed liquid are mixed in the venturi gas-liquid mixer 420 to generate foam, and are transported to the cleaning and disinfection module through a mixing pipeline 421 connected to the venturi gas-liquid mixer 420.

[0089] The waterway mechanism includes a waterway pipeline 412, and a pressure water storage tank 401, a foaming agent liquid barrel 406 and a mixed liquid barrel 409 connected to the waterway pipeline 412; the foaming agent liquid barrel 406 delivers the foaming agent liquid to the mixed liquid barrel 408 through the automatic doser 405. A filter 402, a first pressure reducing valve 403 and a first solenoid valve 404 are connected between the pressure water storage tank 401 and the mixed liquid barrel 409, and the depressurized clean water is delivered to the mixed liquid barrel 408 through the first pressure reducing valve 403 to be mixed with the foaming agent liquid according to a set ratio. A second liquid level sensor 407 is preferably provided in the foaming agent liquid barrel 406, and when the foaming agent liquid is lower than the set value, it is prompted to replenish the foaming agent liquid. A first liquid level sensor 409 is provided in the mixed liquid barrel 408. When the liquid level in the mixed liquid barrel 408 is lower than a set value, the first solenoid valve 404 is opened, and when clean water flows through the automatic doser 405, a negative pressure is generated at the liquid suction port to automatically draw in the foaming agent stock solution, and the foaming agent stock solution is mixed with the clean water and flows into the mixed liquid barrel 408; when the liquid level in the mixed liquid barrel 408 is higher than an upper limit, the first solenoid valve 404 is automatically closed, and the automatic doser 405 stops working.

[0090] A second solenoid valve 410, a flow meter 411, a plunger pump 413 and a pressure sensor 414 are provided on the water pipe 412 after the mixed liquid barrel 408, so that the plunger pump 413 can be operated at a variable frequency by a control mechanism according to the pressure detected by the pressure sensor 414 and the flow detected by the flow meter 411.

[0091] The gas circuit mechanism includes a gas circuit pipeline 418 and an air compressor 415 connected to the gas circuit pipeline 418, a second pressure reducing valve 416, a third solenoid valve 417 and a check valve 419; the air compressor 415 is normally open when powered on and has an automatic start-stop device. The function of the check valve 419 is to prevent the foaming agent mixture from entering the gas circuit pipeline 418.

[0092] During foam cleaning, the second solenoid valve 410 at the liquid outlet of the mixed liquid barrel 408, the third solenoid valve 417 of the air pipeline 418 and the plunger pump 413 are powered on and opened, and the foaming agent mixed liquid in the mixed liquid barrel 408 flows into the water inlet of the Venturi gas-liquid mixer 420 through the water channel, and the compressed air flows into the air inlet of the Venturi gas-liquid mixer 420 through the air pipeline 418. The mixed liquid and the compressed air are mixed in the mixing chamber of the Venturi gas-liquid mixer 420 to form a gas-liquid two-phase fluid, and the gas-liquid two-phase fluid is sprayed out through the nozzle assembly / foam nozzle 129 of the cleaning and disinfection module to form foam.

[0093] The control mechanism is respectively connected to the plunger pump 413, the first solenoid valve 404, the second solenoid valve 410, the third solenoid valve 417 and the pressure sensor 414. The operating frequency of the plunger pump 413 is sensed and controlled by the pressure sensor 414. After the control mechanism sets a certain pressure value, the plunger pump 413 will realize automatic frequency conversion control through the pressure value of the pressure sensor 414 to keep the pressure of the pipeline system constant.
