[0074] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0075] To address the problem that existing roadway sprinkler systems cannot automatically stop spraying when pedestrians or vehicles pass by, this invention provides a roadway delayed sprinkler system.

[0076] The tunnel delayed spraying system of this utility model embodiment includes a spraying component 1, a spraying control valve 2, a switching valve 3, a pedal valve 4, and a delay component 5.

[0077] The spray control valve 2 is used to control the start and stop of the spray assembly 1. In other words, the start and stop of the spray assembly 1 can be controlled by controlling the opening and closing of the spray control valve 2. For example, when the spray control valve 2 is in the open state, the spray assembly 1 is in the start state; when the spray control valve 2 is in the closed state, the spray assembly 1 is in the stop state.

[0078] The switching valve 3 is connected to the spray control valve 2. The switching valve 3 can switch between a first switching state that controls the spray control valve 2 to open and a second switching state that controls the spray control valve 2 to close. That is, when the switching valve 3 is in the first state, the spray control valve 2 is in the open state, and when the switching valve 3 is in the second state, the spray control valve 2 is in the closed state.

[0079] The pedal valve 4 is connected to the switching valve 3. The pedal valve 4 is used to control the switching valve 3 to switch from the first switching state to the second switching state. That is, when the pedal valve 4 is in the open state, the switching valve 3 can switch from the first switching state to the second switching state. If the switching valve 3 is already in the second switching state, even if the switching valve 3 is reopened, the switching valve 3 will still be in the second switching state.

[0080] The delay component 5 includes a delay valve 501 and a delay trigger component 502. The delay valve 501 is connected to the switching valve 3. The delay valve 501 is used to control the switching valve 3 to switch from the second switching state to the first switching state. That is, when the delay valve 501 is in the open state, the switching valve 3 can switch from the second switching state to the first switching state.

[0081] The switching valve 3 is connected to the delay trigger component 502. When the switching valve 3 switches from the first switching state to the second switching state, the switching valve 3 controls the delay valve 501 through the delay trigger component 502 to control the switching valve 3 to switch from the second switching state to the first switching state with a delay.

[0082] In other words, when the pedal valve 4 controls the switching valve 3 to switch from the first switching state to the second switching state, the switching valve 3 can control the delay trigger component 502 so that the delay valve 501 controls the switching valve 3 to switch from the second switching state to the first switching state after a preset time.

[0083] It is understandable that when the switching valve 3 is in the first switching state, the spray control valve 2 is in the open state, and the spray assembly 1 is in the open state.

[0084] Therefore, the pedal valve 4 can be installed on the ground of the tunnel. When no pedestrians or vehicles pass by, the pedal valve 4 is in the closed state. When pedestrians or vehicles pass by, the pedal valve 4 switches to the open state under the action of rolling or stepping. Then, the switching valve 3 switches from the first switching state to the second switching state, the sprinkler control valve 2 is in the closed state, and the sprinkler assembly 1 is in the closed state.

[0085] This achieves the effect of stopping the spraying of the spraying component 1 when pedestrians or vehicles pass by.

[0086] Meanwhile, the switching valve 3 can control the delay trigger component 502 to make the delay valve 501 control the switching valve 3 to switch from the second switching state to the first switching state after a preset time.

[0087] In other words, the spray assembly 1 will automatically restart spraying after a preset time after pedestrians or vehicles have passed by and the spraying stops, so that the spraying can resume after pedestrians or vehicles have left.

[0088] Therefore, the tunnel delayed spraying system of this utility model embodiment can stop spraying when pedestrians or vehicles pass by, and can also restart spraying after pedestrians or vehicles leave.

[0089] In some embodiments, the spray assembly 1 includes a nozzle 101 and a spray air-water pipeline 102. The nozzle 101 has a spray water inlet and a spray air inlet. The spray air-water pipeline 102 has a spray air outlet and a spray water outlet. The spray air outlet is connected to the spray air inlet, and the spray water outlet is connected to the spray water inlet.

[0090] The spray control valve 2 is located on the spray air and water pipeline 102 and is used to control the on / off state of the spray air and water pipeline 102.

[0091] Furthermore, the spray air and water pipeline 102 includes a spray air pipeline 1021 and a spray water pipeline 1022. The spray air outlet is located on the spray air pipeline 1021, and the spray air pipeline 1021 is connected to the spray head 101 through the spray air outlet and the spray air inlet, so as to supply air to the spray head 101. The spray water outlet is located on the spray water pipeline 1022, and the spray water pipeline 1022 is connected to the spray head 101 through the spray water outlet and the spray water inlet, so as to supply water to the spray head 101.

[0092] Meanwhile, the spray control valve 2 includes a portion located on the spray air pipeline 1021 and a portion located on the spray water pipeline 1022, thereby enabling simultaneous control of the effects of the spray water pipeline 1022 and the spray air pipeline 1021.

[0093] Meanwhile, the spray control valve 2 has a start control air inlet 201 and a stop control air inlet 202, and the switching valve 3 has a first switching air outlet 301 and a second switching air outlet 302. The first switching air outlet 301 is connected to the start control air inlet 201, and the second switching air outlet 302 is connected to the stop control air inlet 202.

[0094] The switching valve 3 also has a first switching inlet 303, a first trigger switching inlet 304, and a second trigger switching inlet 305. When air is supplied to the first trigger switching inlet 304, the switching inlet 303 is connected to the first switching outlet 301; when air is supplied to the second trigger switching inlet 305, the switching inlet 303 is connected to the second switching outlet 302.

[0095] It also includes a trigger air line 6, which is connected to the second trigger switching air inlet 305. A pedal valve 4 is located on the trigger air line 6. When pedestrians and vehicles pass by the pedal valve 4, the pedal valve 4 opens, allowing the trigger air line 6 to supply air to the second trigger switching air inlet 305, so that the switching valve 3 is in the second switching state, thereby connecting the switching air inlet 303 with the second switching outlet. At the same time, the second switching air outlet 302 is connected to the stop control air inlet 202, thereby controlling the spray control valve 2 to close, and thus controlling the spray assembly 1 to close.

[0096] When the switching valve 3 is in the first switching state, the switching air inlet 303 is connected to the first switching outlet, and the first switching air outlet 301 is connected to the start control air inlet 201, thereby controlling the spray control valve 2 to open, and thus controlling the spray assembly 1 to open.

[0097] It also includes a delay air line 7, which is connected to the first trigger switching air inlet 304. A delay valve 501 is provided on the delay air line 7. The delay trigger assembly 502 includes a telescopic cylinder 5021, a rack 5022, and a spring 5023. The spring 5023 is connected to the rack 5022. The telescopic end of the telescopic cylinder 5021 is adapted to abut against the rack 5022. The rack 5022 can switch between a first state of closing the delay valve 501 and a second state of opening the delay valve 501.

[0098] The telescopic cylinder 5021 has a first telescopic air inlet 50211 and a second telescopic air inlet. The first telescopic air inlet 50211 is connected to the first switching air outlet 301, and the second telescopic air inlet 50212 is connected to the second switching air outlet 302. When the first telescopic air inlet 50211 is ventilated, the telescopic end of the telescopic cylinder 5021 extends and drives the rack 5022 to switch to the first state. When the second telescopic air inlet 50212 is ventilated, the telescopic end of the telescopic cylinder 5021 retracts, and the spring 5023 drives the rack 5022 to switch to the second state.

[0099] like Figure 3 As shown, the telescopic end of the telescopic cylinder 5021 extends, pushing the rack 5022 to the left. The rack 5022 presses down the switch of the delay valve 501, and the delay valve 501 is in the closed state. If the telescopic end of the telescopic cylinder 5021 retracts, under the action of the spring 5023, the rack 5022 will slowly move to the right, switching to the second state. That is, when the rack 5022 moves to the position where it abuts against the telescopic cylinder 5021, it stops, the switch of the delay valve 501 pops out, and the delay valve 501 is in the open state, thereby supplying air to the first trigger switching air inlet 304. The switching valve 3 is in the first switching state. The first switching air outlet 301 is connected to the switching air inlet 303, supplying air to the first telescopic air inlet 50211. The telescopic end of the telescopic cylinder 5021 extends and drives the rack 5022 to switch to the first state, and the delay valve 501 is closed again.

[0100] The first switching air outlet 301 supplies air to the start control air inlet 201, controlling the spray control valve 2 to open, thereby causing the spray assembly 1 to start again.

[0101] This ensures that the sprinkler assembly 1 automatically restarts after a preset time has elapsed since it was turned off, and the delay assembly 5 also automatically resets so that it can be triggered again when the next pedestrian or vehicle passes by.

[0102] It is understood that the tunnel delayed sprinkler system of this utility model embodiment does not use electronic components for control, but controls the action of each valve body entirely through the air circuit, which can greatly improve the explosion-proof performance of the tunnel delayed sprinkler system of this utility model embodiment.

[0103] In some embodiments, the spray air-water pipeline 102 includes a spray air pipeline 1021 and a spray water pipeline 1022. The spray air pipeline 1021 is provided with a first regulating valve 8, which can regulate the flow rate of the gas in the spray air pipeline 1021, thereby regulating the spray size of the nozzle 101.

[0104] In some embodiments, the tunnel delayed spraying system of this utility model further includes a main air pipeline 9, a trigger air pipeline 6 connected to the main air pipeline 9, and a delayed air pipeline 7 connected to the main air pipeline 9.

[0105] A second regulating valve 10 is provided on the main gas pipeline 9, which can regulate the gas flow rate of the main gas pipeline 9.

[0106] It is also understandable that the main air line 9 and the spray air line 1021 can be connected to the same air source, saving costs.

[0107] In some embodiments, the tunnel delayed spraying system of this utility model further includes a pedal 11. The pedal 11 includes a base plate 111 and a movable plate 112. The movable plate 112 is disposed above the base plate 111, and the movable plate 112 and the base plate 111 are supported by an elastic element 113. The pedal valve 4 is disposed on the base plate 111 and is connected to the movable plate 112. The movable plate 112 can move in the vertical direction to drive the pedal valve 4 to open and close.

[0108] In other words, when the movable plate 112 is pressed down, the pedal valve 4 opens, and when the movable plate 112 is not pressed down, the pedal valve 4 closes.

[0109] In some embodiments, the base plate 111 is further provided with a plurality of support ribs 114, and the plurality of support ribs 114 are spaced apart along the length direction of the base plate 111.

[0110] The support rib 114 extends in the width direction of the pedal 11. The upper surface of the support rib 114 is provided with a first sliding groove 1141 and a second sliding groove 1142. The first sliding groove 1141 and the second sliding groove 1142 extend in the width direction of the pedal 11.

[0111] The movable plate 112 has a first guide plate 1121 and a second guide plate 1122. The first guide plate 1121 extends along the length of the pedal 11 and is slidably fitted in the first sliding groove 1141. The second guide plate 1122 extends along the width of the pedal 11 and is slidably fitted in the second sliding groove 1142.

[0112] By setting the first sliding groove 1141 and the second sliding groove 1142, the first guide plate 1121 and the second guide plate 1122 can be guided respectively, so as to avoid the movable plate 112 from deviating when sliding in the vertical direction.

[0113] In some embodiments, the pedal 11 further includes a first guide wheel assembly 115, which includes two first guide wheels 1151. The two first guide wheels 1151 are disposed on the base plate 111 and are spaced apart in the width direction of the pedal 11. The movable plate 112 has a first sidewall 1123 and a second sidewall 1124 disposed opposite to each other in the width direction of the pedal 11, and the two first guide wheels 1151 abut against the first sidewall 1123 and the second sidewall 1124 respectively.

[0114] By setting the first guide wheel set 115, the movable plate 112 can be limited in the width direction of the pedal 11.

[0115] In some embodiments, the pedal 11 further includes a second guide wheel assembly 116, which includes two second guide wheels 1161. The two second guide wheels 1161 are disposed on the movable plate 112 and are spaced apart in the length direction of the pedal 11. The support rib plate 114 has a third side wall 1143 and a fourth side wall 1144 disposed opposite to each other in the length direction of the pedal 11, and the two second guide wheels 1161 abut against the third side wall 1143 and the fourth side wall 1144 respectively.

[0116] By setting the second guide wheel set 116, the movable plate 112 can be limited in the field direction of the pedal 11.

[0117] In some embodiments, the pedal 11 further includes a first guide plate 117 and a second guide plate 118, and the support rib 114 has a first guide slope 1145 and a second guide slope 1146, the first guide slope 1145 and the second guide slope 1146 being respectively disposed at both ends of the support rib 114 in the width direction of the pedal 11; the first guide plate 117 is disposed on the first guide slope 1145; and the second guide plate 118 is disposed on the second guide slope 1146.

[0118] By setting the first guide plate 117 and the second guide plate 118, pedestrians and vehicles can be guided to pass through the step plate 11.
