If it is determined that the first valve 52 and the second valve 62 are both opened, the disinfecting liquid is injected from both the first nozzle group 60 and the second nozzle group 70, and a small vehicle is detected by the determination unit 86. When it is determined as S, the controller 87 is configured to open only the first valve 52 and inject the disinfectant liquid from only the first nozzle group 60.

  As shown in FIG. 9, the control means 42 includes a pump 48, a first valve 52, a second valve 62, a first drive body 74, a second drive body 75, a first detection means 81, and a second detection means. 82, the lighting means 83, the driving member 28 of the first opening / closing means 24 and the driving member 31 of the second opening / closing means 25 are electrically connected.

  Further, the vehicle disinfection apparatus 1 includes a purifying unit 91 that purifies the disinfecting liquid (disinfecting waste liquid) after disinfecting the vehicle S.

  As shown in FIG. 1, the purification means 91 is connected to the end of the concave groove 4 of the floor portion 2 via a pipe 92 and temporarily stores the disinfecting liquid from the concave groove 4. A grease trap 95 connected to the grease trap 95 via a pipe 96, an aeration tank 97 connected to the grease trap 95 via a pipe 96, a septic tank 99 connected to the aeration tank 97 via a pipe 98, and A discharge pipe 100 is connected to the septic tank 99 and discharges the sterilized liquid after purification to, for example, a sewage main pipe. In the warehouse 17, a boiler 12, a header 13, a pump 48, a control means 42, a grease trap 95, and the like are disposed.

  Next, the operation of the vehicle disinfection device 1 will be described.

  First, the case where the vehicle S enters a livestock facility such as a ranch will be described.

  When the vehicle S travels in the entrance direction and enters one end in the longitudinal direction of the vehicle travel surface 2a of the floor 2 and the first detection means 81 and the second detection means 82 simultaneously detect the vehicle S, based on this detection, The control means 42 determines that the vehicle S has entered and determines whether the vehicle S is a large vehicle S or a small vehicle S.

  When the control means 42 determines that the vehicle S has entered, the control means 42 starts to raise the opening / closing member 26 of the first opening / closing means 24 and the opening / closing member 29 of the second opening / closing means 25, and turns the lighting means 85 red. Turn on. Then, the control means 42 operates the pump 48 when the opening and closing members 26 and 29 are raised to a predetermined fully open position.

  When the control means 42 does not receive the vehicle presence detection signals from both the detection means 81 and 82 at the same time and determines that a person other than the vehicle S has entered, for example, the opening / closing means 24 and 25 and the lighting means Do not operate 85. That is, it does not malfunction due to an approaching object other than the vehicle S.

  Subsequently, when the determination result of the determination unit 86 is the large vehicle S, the control means 42 switches both the first valve 52 and the second valve 62 from the closed state to the open state.

  Then, as shown in FIGS. 3A and 3B, disinfecting liquid is ejected from the first nozzles 56 and 57 of the lower first nozzle group 60, and the second of the second nozzle group 70 on the upper side. Disinfectant is sprayed from the nozzles 66 and 67. As a result, the large vehicle S is sterilized with a desired amount of disinfectant from both nozzle groups 60 and 70 while passing through the vehicle passage space 23 in the apparatus main body 16.

  The control means 42 opens the corresponding opening / closing portion 73 of the tube cover body 77 by opening the corresponding first opening / closing body 71 and second opening / closing body 72 before the nozzle groups 60, 70 spray the disinfectant. Keep open.

  Thereafter, when the control means 42 determines that the large vehicle S has passed through the vehicle passage space 23 based on the detection of both the detection means 83 and 84, it stops the pump 48 and closes both the valves 52 and 62 from the open state. Switch to the state, lower both open / close members 26 and 29 to a predetermined fully closed position, return the first open / close body 71 and the second open / close body 72 to the closed state, and close the opening hole 73 of the tube cover body 77. .

  On the other hand, when the determination result of the determination unit 86 is the small vehicle S, the control means 42 switches only the first valve 52 from the closed state to the open state.

  Then, as shown in FIGS. 4A and 4B, the disinfecting liquid is ejected only from the first nozzles 56 and 57 of the lower first nozzle group 60. As a result, the small vehicle S is disinfected with the desired amount of the disinfectant from the first nozzle group 60 while passing through the vehicle passage space 23 in the apparatus main body 16.

  The control means 42 opens the corresponding opening / closing portion 73 of the tube cover body 77 by opening the corresponding first opening / closing body 71 before the first nozzle group 60 ejects the disinfectant.

  Thereafter, when the control means 42 determines that the small vehicle S has passed through the vehicle passage space 23 based on the detections of the detection means 83 and 84, the control means 42 stops the pump 48 and closes the first valve 52 from the open state to the closed state. And the both opening and closing members 26 and 29 are lowered to a predetermined fully closed position. Further, the first opening / closing body 71 is returned to the closed state, and the opening hole 73 of the tube cover body 77 is closed.

  The sterilized waste liquid after disinfecting the vehicle S flows through the concave groove 4 and is supplied to the purification means 91. After being purified by the purification means 91, the waste liquid is discharged to a discharge section such as a sewage main pipe, for example. Is done. Further, for example, in winter, the heating means 3 operates to heat the floor 2 so that the temperature inside the apparatus main body 16 is maintained at a predetermined temperature or higher.

  Next, the case where the vehicle S leaves the livestock facility such as a ranch will be described. In this case, the disinfection process is basically not performed.

  When the vehicle S travels in the entry direction and enters the other end in the longitudinal direction of the vehicle travel surface 2a of the floor portion 2, and the third detection means 83 and the fourth detection means 84 detect the vehicle S simultaneously, based on this detection. The control means 42 determines that the vehicle S has entered, starts raising the opening / closing member 26 of the first opening / closing means 24 and the opening / closing member 29 of the second opening / closing means 25, and lights the lighting means 85 in red.

  When the control means 42 does not receive the vehicle presence detection signals from both the detection means 83 and 84 at the same time and determines that a person other than the vehicle S, for example, has entered, the opening / closing means 24 and 25 and the lighting means Do not operate 85.

  Thereafter, when the control means 42 determines that the vehicle S has passed through the vehicle passage space 23 based on the detection of both the detection means 81 and 82, the control means 42 lowers both the opening and closing members 26 and 29 to a predetermined fully closed position. Both openings 21 and 22 of the main body 16 are closed.

  And according to such a vehicle disinfection apparatus 1, in the case of the large vehicle S, disinfection liquid from both the 1st nozzle group 60 and the 2nd nozzle group 70 based on control of the disinfection liquid injection means 41 by the control means 42. In the case of the small vehicle S, the disinfecting liquid is injected only from the first nozzle group 60, so that an appropriate disinfecting operation can be performed while preventing the disinfecting liquid from being wasted.

  The first opening / closing body 71 is opened when the first nozzle group 60 is jetted and closed when the first nozzle group 60 is not jetted. The second opening / closing body 72 is opened when the second nozzle group 70 is jetted. Since the second nozzle group 70 is in a closed state when not injecting, for example, it is possible to prevent the disinfectant from freezing in the nozzle attachment pipes 53 and 63 or in the nozzle in winter, and more appropriate disinfection work can be performed.

  Furthermore, since the heating means 3 for heating the floor portion 2 on which the vehicle S travels is provided, freezing of the disinfectant solution in winter can be effectively prevented, and more appropriate disinfection work can be performed. That is, with the conventional vehicle disinfection device, the disinfectant may freeze and become unusable in winter in areas such as Hokkaido, but the vehicle disinfection device 1 of the present invention may disinfect disinfectant in winter even in regions such as Hokkaido. However, it does not freeze in the nozzle mounting pipes 53, 63 and the nozzles 56, 57, 66, 67, so that the freezing of the disinfectant can be surely prevented, and more appropriate disinfection work can be performed.

  Further, since the purifying means 91 for purifying the disinfecting liquid after disinfecting the vehicle S is provided, the disinfecting liquid after disinfecting the vehicle S can be purified and detoxified by the purifying means 91. And natural destruction by disinfectant can be prevented.

  The nozzle mounting pipes 53 and 63 are not limited to the cylindrical pipes as shown in FIGS. 10 to 12, but may be quadrangular cylindrical pipes as shown in FIGS. In the case of this configuration, the nozzle mounting pipes 53 and 63 have a plurality of concave portions 101, and nozzles 57, 66, and 67 are attached to the bottom surface portion 102 of the concave portions 101, and the nozzles 57, 66, and 67 are concave portions. Located in 101. In addition, in the internal space 104 in the concave portion 101, a portion located on the same plane as the plate portion 103 that constitutes a part of the nozzle attachment pipes 53 and 63 is an opening hole portion 73.

  13 to 15, the opening / closing body 71 slidably moved relative to the plate portion 103 of the nozzle mounting pipes 53, 63 based on the control of the driving bodies 74, 75 by the control means 42. The opening hole 73 is opened and closed by 72. That is, the first opening / closing body 71 is opened when the first nozzle group 60 is jetted, and is closed when the first nozzle group 60 is not jetted, and the second opening / closing body 72 is jetted by the second nozzle group 70. Sometimes it is open, and when the second nozzle group 70 is not injecting, it is closed.

  Further, for example, all the nozzles 56, 57, 66, 67 may be exposed (opened) only when the disinfecting liquid is ejected. For example, the nozzles 56, 57, 66, 67 are not covered with the tube cover body 77. A configuration in which all or a part is always exposed may be used.

  Further, the detection means 81, 82, 83, 84 are not limited to the opposed type comprising a light emitting part and a light receiving part that are spaced apart from each other. For example, a regression reflection type using a reflection plate or a reflection plate is used. Instead, a diffuse reflection type that detects a change in reflected light from the vehicle may be used.

  Moreover, the heating means 3 for heating the floor 2 may use, for example, photovoltaic power generation.

Furthermore, the example of the vehicle disinfection apparatus 1 which concerns on the related technique of this invention is shown in FIG.16 and FIG.17.

  In this vehicle disinfection device 1, the first nozzle mounting tube 53 and the second nozzle mounting tube 63 are each formed in a loop shape (rectangular ring or the like) and heated by a disinfectant heating means (not shown) to set temperature. The disinfectant set to (for example, about 70 degrees) is circulated through the nozzle mounting tubes 53 and 63 at a low pressure. In addition, nozzles 56, 57, 66, and 67 are attached to the nozzle attachment portions of the nozzle attachment pipes 53 and 63 via the pressure valve 110. The pressure valve 110 automatically switches from the closed state to the open state when the pressure of the disinfecting liquid circulating through the nozzle mounting pipes 53 and 63 reaches a preset set pressure. The outer peripheral surfaces of the nozzle mounting tubes 53 and 63 are covered with a heat insulating material 111.

  In such a vehicle disinfection device 1, a high temperature disinfectant that is a set temperature circulates in the nozzle mounting pipes 53 and 63 at a low pressure when no disinfectant is ejected. In this case, the control means 42 raises the pressure of the disinfecting liquid in both nozzle attachment pipes 53 and 63 to the set pressure when it is determined that the vehicle that is the disinfecting liquid injection target is a large vehicle. Disinfecting liquid is injected from both the group (first nozzles 56, 57) 60 and the second nozzle group (second nozzles 66, 67) 70, and the vehicle that is the disinfecting liquid injection target is determined to be a small vehicle. In this case, the disinfecting liquid is sprayed from only the first nozzle group (first nozzles 56 and 57) 60. For this reason, not only can the waste of the disinfectant be prevented, but also the disinfectant does not freeze in the nozzle mounting pipes 53, 63 and the nozzles 56, 57, 66, 67 even in the winter, and the disinfectant is injected. Good reactivity.

  An open / close valve is provided in the middle of the loop-shaped nozzle attachment pipes 53 and 63, and the open / close valve is closed except in winter, and the open / close valve is opened only in winter to circulate high-temperature disinfectant. Good.

  For example, as shown in FIG. 18, in order to prevent the disinfectant from freezing, the hot water pipe 11 of the heating means 3 is disposed in the vicinity of the nozzle mounting pipes 53 and 63, and the hot water pipe 11 and the nozzle mounting pipe 53 are disposed. 63 may be covered with a heat insulating material 112. That is, for example, in winter, the heating means 3 that is a floor heating device uses warm water to heat the floor portion 2 and heats the disinfectant (nozzle attachment tubes 53 and 63) to a predetermined temperature (for example, about 70 degrees). It is good also as composition to do.
