[0052] The present application provides a cleaning operation vehicle. The cleaning operation vehicle of the present application is described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0053] Combination Figures 1 to 14 As shown, the cleaning operation vehicle 1 is applied to the aviation fuel operation system. The aviation fuel supply system includes an oil storage well, a refueling hydrant and a refueling valve. The cleaning operation vehicle 1 is applicable to the airport to clean the apron pipe network hydrant well and the apron pipe network valve well.

[0054] Specifically, the cleaning operation vehicle 1 includes a chassis 101 and a frame 102, a sewage suction device 103, a cleaning device 104, an air extraction device 105 and a purge device 106 assembled on the chassis 101. The chassis 101 is used to support the frame 102, the sewage suction device 103, the cleaning device 104, the air extraction device 105 and the purge device 106. The frame 102 is convexly arranged on the surface of the chassis 101. The sewage suction device 103 is used to suck sewage, leaves, weeds, cotton wool, mud and other impurities in the oil storage well. The cleaning device 104 is used to clean the refueling hydrant and the refueling valve. The air extraction device 105 is used to remove toxic and / or harmful gases in the oil storage well, so that the underground operation reduces the safety hazard of poisoning. The purge device 106 is used to dry the cleaned oil storage well, the refueling hydrant and the refueling valve in time. Such arrangement optimizes the function of the cleaning operation vehicle 1, meets the operation requirements of the aviation fuel operation system, and has practical value for the development of the aviation industry.

[0055] In some embodiments, the chassis 101 extends along a first direction X1 and a second direction X2 in a horizontal plane, and the second direction X2 is perpendicular to the first direction X1. The first direction X1 can be the direction in which the cleaning vehicle 1 is traveling. In this embodiment, the mass range of the chassis 101 is 2500kg to 2600kg, and the preferred value is 2560kg. The maximum load-bearing mass range is 8200kg to 8300kg, and the preferred value is 8280kg. After calculation, the ratio of the steering axle load of the chassis 101 to the chassis mass and the total mass of the cleaning vehicle 1 is greater than or equal to 20% when the chassis 101 is unloaded and fully loaded, respectively, which meets the requirements, thereby ensuring that the chassis 101 is stable and reliable. As an important component of the cleaning vehicle 1, the reliability, stability, driving comfort, and intelligence of the chassis 101 affect the overall performance of the cleaning vehicle 1.

[0056] In some embodiments, the sewage suction device 103 includes a vacuum tank 109, a sewage suction gun 110, a sewage suction hose 111 and a vacuum pump 112 (combined with Figures 1 to 6 In some embodiments, the vacuum tank 109 is extended along the first direction X1 to effectively utilize the space of the chassis 101 in the first direction X1.

[0057] In some embodiments, the sewage suction gun 110 is detachably assembled on the frame 102 and is located outside the frame 102 in the second direction X2. The frame 102 has a height relative to the surface of the chassis 101, so that the sewage suction gun 110 provided on the frame 102 is easy to take and convenient for the staff to use. When sewage suction work is required, the staff removes the sewage suction gun 110 from the frame 102 to perform the sewage suction operation. After the sewage suction is completed, the sewage suction gun 110 is placed on the frame 102. When the sewage suction gun 110 is placed on the frame 102, the end connecting the sewage suction gun 110 and the sewage suction hose 111 is hung on the frame 102, and the sewage suction port of the sewage suction gun 110 is extended downward along the longitudinal axis direction. Such a configuration ensures that the sewage or impurities remaining in the sewage suction gun 110 can be further discharged.

[0058] In some embodiments, the dirt suction hose 111 is assembled to the frame 102 and is located inside the frame 102 in the second direction X2. The dirt suction hose 111 can be fixed to the frame 102 using a first hose bracket. Since the dirt suction hose 111 occupies a large area, the dirt suction hose 111 is arranged inside the frame 102 relative to the dirt suction gun 110, and the space of the frame 102 is reasonably utilized, so that the layout of the entire cleaning operation vehicle 1 is more compact. And ensure that the dirt suction gun 110 and the dirt suction hose 111 are staggered to avoid mutual influence.

[0059] In some embodiments, the vacuum pump 112 is assembled on the chassis 101, and the vacuum pump 112 and the frame 102 are distributed along the second direction X2. The frame 102 is located outside the chassis 101 relative to the vacuum pump 112. Since the vacuum pump 112 occupies a large area and is connected to the vacuum tank 109, the vacuum pump 112 is arranged on the side of the chassis 101 close to the vacuum tank 109. The frame 102 and the vacuum tank 109 are distributed along the first direction X1, which effectively utilizes the space of the chassis 101 and makes the layout of the entire cleaning operation vehicle 1 compact.

[0060] exist Fig.12In the embodiment shown, the dirt suction gun 110 is connected to the dirt inlet of the vacuum tank 109 through the dirt suction hose 111, and the vacuum pump 112 is connected to the vacuum tank 109. When the dirt suction device 103 performs the dirt suction work, the vacuum pump 112 is used to extract the gas in the vacuum tank 109, a certain vacuum degree is formed in the vacuum tank 109, and the sewage outside the vacuum tank 109 is sucked into the vacuum tank 109 by the pressure difference between the inside and outside of the vacuum tank 109. Since the vacuum pump 112 does not directly pump water, it avoids sensitivity to solid impurities in the sewage. And since the vacuum volume of the vacuum tank 109 is large enough, the small amount of air entering from the dirt suction hose 111 can be ignored, so that the residual liquid can be ensured to be drained. In addition, when the diameter of the dirt suction hose 111 is appropriate, solid impurities such as leaves, weeds, cotton wool, mud and sand can also be directly sucked into the vacuum tank 109 without manual auxiliary treatment, so that the operation efficiency can be significantly improved. When the dirt suction operation is completed, the cleaning vehicle 1 drives to the dirt discharge point and opens the dirt discharge valve in the vacuum tank 109 to discharge. In this way, the dirt suction performance of the cleaning vehicle 1 is optimized by adopting the vacuum dirt suction principle.

[0061] In some embodiments, the cleaning device 104 includes a clean water tank 113, a water spray gun 114, a cleaning hose 115, a filter 116, and a cleaning machine 117 (combined with Figures 1 to 6 , Fig.11 As shown).

When cleaning work is required, the staff removes the water spray gun 114 from the frame 102 for cleaning operation. After the cleaning is completed, the water spray gun 114 is placed on the frame 102. When the water spray gun 114 is placed on the frame 102, one end connecting the water spray gun 114 and the cleaning hose 115 is hung on the frame 102, and the water spray port of the water spray gun 114 is extended downward along the longitudinal axis direction. In this way, it is ensured that the sewage remaining in the water spray gun 114 can be further discharged.

[0063] In some embodiments, the cleaning hose 115 is assembled on the frame 102 and is located on the inner side of the frame 102 in the second direction X2. The cleaning hose 115 can be fixed to the frame 102 by a second hose bracket. The second hose bracket and the first hose bracket are arranged side by side on the frame 102 in the first direction X1. Since the cleaning hose 115 occupies a large area, the cleaning hose 115 is arranged on the inner side of the frame 102 relative to the water spray gun 114, and the space of the frame 102 is reasonably utilized, so that the layout of the entire cleaning operation vehicle 1 is more compact. And ensure that the water spray gun 114 and the cleaning hose 115 are staggered to avoid mutual influence.

[0064] In some embodiments, the cleaning machine 117 is assembled on the chassis 101. The cleaning machine 117 and the frame 102 are distributed along the second direction X2. Since the cleaning machine 117 occupies a large area, the frame 102 is located outside the chassis 101 relative to the cleaning machine 117, which effectively utilizes the space of the chassis 101 and makes the entire cleaning operation vehicle 1 compact.

[0065] exist Fig.13 In the embodiment shown, the water outlet of the clean water tank 113 is connected to the liquid inlet of the filter 116, the liquid outlet of the filter 116 is connected to the liquid inlet of the cleaning machine 117, and the liquid outlet of the cleaning machine 117 is connected to the water spray gun 114 through the cleaning hose 115. In some embodiments, the cleaning machine 117 is a high-pressure cleaning machine. In this embodiment, the high-pressure cleaning machine is equipped with a 12m to 15m long high-pressure hose with a diameter of 3mm to 9mm. On the one hand, the cleaning machine 117 is used to clean the refueling hydrant and the refueling valve in the oil storage well, and can also discharge the clean water in the clean water tank 113 under high pressure. This arrangement is used to clean the refueling hydrant and the refueling valve.

[0066] In some embodiments, the exhaust device 105 includes an exhaust fan 118, an exhaust hose 119, and an exhaust pipe 120 (such as Figure 1 ). The exhaust fan 118 is extended along the first direction X1 and is distributed with the vacuum tank 109 along the second direction X2. The exhaust fan 118 and the clean water tank 113 are located on both sides of the vacuum tank 109 in the second direction X2. The exhaust fan 118 and the clean water tank 113 are arranged on both sides of the vacuum tank 109, and the space on both sides of the vacuum tank 109 is effectively utilized. When the length and volume of the cleaning operation vehicle 1 remain unchanged, the volume and capacity of the vacuum tank 109 are increased, and the layout of the entire cleaning operation vehicle 1 is made more compact. In some embodiments, the frame 102 and the exhaust fan 118 are located on the same side of the chassis 101 in the second direction X2.

[0067] The exhaust fan 118, the exhaust hose 119 and the exhaust pipe 120 are detachably assembled. When exhaust is needed, one end of the exhaust hose 119 is connected to the air inlet of the exhaust fan 118, and one end of the exhaust pipe 120 is connected to the air outlet of the exhaust fan 118 to remove toxic and harmful gases in the well, so that underground operations can reduce the safety hazards of poisoning. After the exhaust is completed, the exhaust fan 118, the exhaust hose 119 and the exhaust pipe 120 are disassembled, and the exhaust fan 118 is stored on one side of the vacuum tank 109 for easy storage. The exhaust hose 119 and the exhaust pipe 120 are stored.

The frame 102 has a height relative to the surface of the chassis 101, so that the spray gun 121 provided on the frame 102 is easy to take and convenient for the staff to use. When the purge work is required, the staff removes the spray gun 121 from the frame 102 for the purge operation. After the purge is completed, the spray gun 121 is placed on the frame 102. When the spray gun 121 is placed on the frame 102, the end connecting the spray gun 121 and the exhaust hose 119 is hung on the frame 102, and the spray port of the spray gun 121 is extended downward along the longitudinal axis direction. In this way, it is ensured that the spray port of the spray gun 121 is connected to the outside world and the residual gas is discharged.

[0069] In some embodiments, the purge hose 122 is assembled to the frame 102 and is located on the inner side of the frame 102 in the second direction X2. The purge hose 122 can be fixed to the frame 102 by a third hose bracket. The third hose bracket is arranged side by side with the second hose bracket and the first hose bracket on the frame 102 in the first direction X1. Since the purge hose 122 occupies a large area, the purge hose 122 is arranged on the inner side of the frame 102 relative to the water spray gun 114, and the space of the frame 102 is reasonably utilized, so that the layout of the entire cleaning operation vehicle 1 is more compact. And ensure that the spray gun 121 and the purge hose 122 are staggered to avoid mutual influence.

[0070] In some embodiments, the air compressor 123 is assembled on the chassis 101, and the air compressor 123 and the vacuum tank 109 are distributed along the first direction X1, and are distributed along the second direction X2 with the frame 102. Since the air compressor 123 occupies a large area, the frame 102 is located outside the chassis 101 relative to the air compressor 123, which effectively utilizes the space of the chassis 101 and makes the layout of the entire cleaning operation vehicle 1 compact.

[0071] exist Fig.14In the illustrated embodiment, the air jet gun 121 is connected to the air compressor 123 through a purge hose 122. After cleaning the fuel filler plug / fueling valve, the gas storage cylinder is used to provide the air source for the air compressor 123, and the purge operation is carried out through the air jet gun 121 to blow off the water droplets on the fuel filler plug / fueling valve. With such a setting, it is used to achieve timely drying of the cleaned underground well, fuel filler plug and fueling valve.

[0072] In the above solution, by optimizing the functions of the cleaning operation vehicle 1, the working efficiency of the cleaning operation is improved, the time for cleaning the oil storage underground well is shortened from 10 minutes to 5 minutes, avoiding the staff from bending down to operate and reducing the workload. It can also achieve the safety of the cleaning operation vehicle 1.

[0073] In Figures 1 to 8 In the illustrated embodiment, the cleaning operation vehicle 1 includes a first storage box 124 and a second storage box 125, and the second storage box 125 and the first storage box 124 are arranged on both sides of the vacuum tank 109.

Figures 3 to 8 In the illustrated embodiment, when air extraction is not required, the sliding portion 130 is fixedly connected to the fixed portion 129, the exhaust fan 118 is stored in the fan storage box 126, and the rolling door is rolled down to cover the fan storage box 126. In the present embodiment, the fixed portion 129 includes a support plate. The sliding portion 130 includes a slide rail. The extension direction of the support plate and the slide rail is parallel to the extension direction of the chassis 101. The slide rail is slidably connected to the support plate in the second direction X2. The exhaust fan 118 is placed on a movable slide rail for easy use. In the present embodiment, the slide rail can be an industrial heavy-duty slide rail, but is not limited thereto.

[0077] In some embodiments, the first storage box 124 includes a tool storage box 131, and the tool storage box 131 and the fan storage box 126 are arranged side by side along the first direction X1, and are both located on one side of the vacuum tank 109. The tool storage box 131 has a storage space for storing various tools, such as buckets, oil-absorbing felts, etc. This arrangement increases the storage space of the cleaning vehicle 1, and the space utilization rate is high.

[0078] In some embodiments, the second storage box 125 is disposed on the top of the clean water tank 113 (eg Figure 5 As shown). The second storage box 125 extends along the first direction X1 and can be used to place long tools. The door of the second storage box 125 can be supported by an inflatable spring, which can save space to the greatest extent and increase the opening and closing angle. In this way, the storage space of the cleaning operation vehicle 1 is increased, and the space utilization rate is high.

[0079] In some embodiments, the cleaning operation vehicle 1 further includes a pipe storage channel 132, which is provided on the chassis 101. The pipe storage channel 132 is extended along the first direction X1, and the opening of the pipe storage channel 132 is provided at the rear of the chassis 101. In the second direction X2, the pipe storage channel 132 is provided near the exhaust fan 118 relative to the clean water tank 113. This arrangement makes it convenient to take when in use. The sewage suction hose 111, the air extraction hose 119 and the exhaust pipe 120 can be stored in the pipe storage channel 132. This arrangement effectively utilizes the internal space of the chassis 101, and relatively long pipelines are stored, making the layout of the entire cleaning operation vehicle 1 more compact.

[0080] In some embodiments, the cleaning vehicle 1 further includes a rack 133, which is disposed at the bottom of the chassis 101 and extends along the second direction X2. The rack 133 effectively utilizes the space of the chassis 101 in the second direction X2 to store various tools. The cleaning vehicle 1 further includes an emergency rescue device 135, which is stored in the rack 133 (e.g., Figure 1 As shown). With such arrangement, the space in the rack 133 is effectively utilized, and the space utilization rate is high. In this embodiment, the emergency rescue device 135 can be a triangular rescue frame, which is used for emergency rescue during underground operations. In the event of an emergency, the well workers can operate the triangular rescue frame to quickly and forcibly lift the underground workers out of the well, and further rescue them, thereby improving safety.

[0081] See also Figures 9 to 11 As shown, the top surfaces of the first storage box 124 and the second storage box 125 are both lower than the top surface of the vacuum tank 109. Since the capacity of the vacuum tank 109 is large and the height of the vacuum tank 109 is high, the upper space of the chassis 101 is effectively utilized to increase the height of the vacuum tank 109 without increasing the width of the vacuum tank 109. The top surfaces of the first storage box 124 and the second storage box 125 are both lower than the top surface of the vacuum tank 109, which lowers the center of gravity of the entire cleaning operation vehicle 1, thereby increasing the stability of the cleaning operation vehicle 1.

[0082] In some embodiments, the cleaning operation vehicle 1 further includes a ladder 134, which is distributed along the first direction X1 with the clean water tank 113, and the ladder 134 extends downward from the top of the second storage box 125. This arrangement is convenient for maintenance by the staff. The top of the clean water tank 113 is provided with a pattern to facilitate the staff to climb to the top of the clean water tank 113 to avoid slipping when working.

[0083] In some embodiments, the filter 116 is assembled in the vacuum tank 109. The filter 116 is a Y-type filter. The Y-type filter is convenient for disassembly and cleaning. In some embodiments, a sewage outlet 136 is provided at the bottom of the vacuum tank 109, and a cleaning port 137 is provided at the top of the vacuum tank 109.

In some embodiments, a manhole 138 and a manhole cover 139 covering the manhole 138 are provided at the top of the vacuum tank 109, and the manhole 138 and the cleaning port 137 are distributed along the first direction X1.

[0084] In this embodiment, the total capacity of the vacuum tank 109 is 3000L, the rated capacity is 2800L, the oil storage well diameter is 460mm, the depth is about 400mm, the refueling plug diameter is about 260mm, and the amount of sewage stored in the plug well is calculated to be 45L. After calculation, the vacuum pump 112 is used as a safe and reliable vacuum power, with a theoretical pumping speed of 65L / min to 75L / min, and its preferred value is 70L / min, ensuring that 60 plug wells can be cleaned every day. And the vacuum pump 112 is explosion-proof to ensure the safety of sewage extraction. A magnetic flap level gauge is provided in the vacuum tank 109. Through the high liquid level control signal of the magnetic flap level gauge, when the sewage in the vacuum tank 109 reaches 2800L, the signal is transmitted to the pneumatic ball valve on the top of the vacuum tank 109 and the switch of the vacuum pump 112, closing the ball valve and the vacuum pump 112, which plays a safety role and protects the vacuum pump 112.

[0085] In some embodiments, a hydraulic power system is further provided in the cleaning vehicle 1, wherein the hydraulic oil pump constituting the hydraulic power system is in transmission connection with the power take-off on the chassis 101, and the output end of the hydraulic oil cylinder constituting the hydraulic power system is respectively in transmission connection with the vacuum pump 112, the cleaning machine 117 and the exhaust fan 118. The power of the hydraulic system comes from the power take-off on the gearbox, and the power take-off drives the gear pump to pump out pressure oil to drive the above vacuum pump 112, the cleaning machine 117 and the exhaust fan 118 to work.

[0086] In some embodiments, the cleaning vehicle 1 is also provided with an electrical system. When the power take-off is engaged, the power take-off indicator light is on, and the red interlocking indicator light is also on, and the interlocking protection is immediately started. The working states of the vacuum pump 112, the cleaning machine 117 and the exhaust fan 118 are respectively controlled by the corresponding hydraulic valves triggered by the fan start switch, the cleaning machine start switch and the vacuum pump switch. When each hydraulic device is working, the engine of the chassis 101 is automatically adjusted to the corresponding rated speed. In addition, the cleaning vehicle 1 is equipped with a reversing display screen and a camera, and the video signal is connected to the display. At the same time, the reversing gear shifting signal is obtained from the chassis 101 and the signal is connected to the display screen. The top of the cab of the cleaning vehicle 1 is equipped with a warning light, and the dashboard is equipped with a lighting lamp, which are all controlled by the key switch.

An interlocking brake system is further provided in the cleaning vehicle 1, and an interlocking brake function is realized by an interlocking brake structure. The air source for the interlocking function is provided by the chassis 101, so that the parking brake circuit of the chassis 101 is used to realize the interlocking brake.

[0088] See also Fig.15As shown, the cleaning operation vehicle 1 includes at least one wheel stopper 140, at least one brake switch 141, a control device 202 and an interlocking brake structure 143. The interlocking brake structure 143 is fixed to the chassis 101. The control device 202 is connected to the chassis 101, and at least one brake switch 141 is connected to the control device 202. The control device 202 is used to control the braking state of the cleaning operation vehicle 1 according to the on-off state of the brake switch 141. In some embodiments, the wheel stopper 140 triggers the interlocking brake structure 143 to trigger the brake switch 141, so that the brake switch 141 is in the on state. At this time, the control device 202 receives the signal of the brake switch 141 and controls the chassis 101 to be in the unlocked state. In some embodiments, the wheel stopper 140 does not trigger the interlocking brake structure 143, nor does it trigger the brake switch 141, so that the brake switch 141 is in the off state. At this time, the control device 202 can control the chassis 101 to be in the locked state.

[0089] It should be noted that in Fig.15 In the embodiment shown, the wheel stopper 140 and the interlocking brake structure 143 are connected in mechanical structure, as will be described later, and the two are triggered by contact, with the dotted line indicating the relationship between the two. The interlocking brake structure 143 and the brake switch 141 are not connected in mechanical structure, as will be described later, and the two are triggered by induction, with the dotted line indicating the relationship between the two. No further details will be given here.

[0090] Combination Figures 16 to 24 As shown, the interlocking brake structure 143 includes a wheel block box 144 and an interlocking member 145 movably connected to the wheel block box 144. At least one wheel block 140 is detachably placed in the wheel block box 144. The wheel block 140 is placed in the wheel block box 144 to press the interlocking member 145, and the interlocking member 145 triggers the brake switch 141 to unlock. The wheel block 140 is not placed in the wheel block box 144, and the brake switch 141 remains locked. In this way, the cleaning vehicle 1 can be effectively braked to ensure the safety of personnel and equipment, which is safe and reliable.

[0091] Specifically, the wheel block box 144 is formed with a receiving portion 146 and a through hole portion 147 communicated with the receiving portion 146. The receiving portion 146 provides a storage space. The wheel block 140 is detachably placed in the receiving portion 146. The interlocking member 145 is installed in the through hole portion 147 and is at least partially located in the receiving portion 146. The interlocking member 145 is movably connected to the wheel block box 144. In this embodiment, the cross section of the wheel block 140 is triangular, and the surface of the wheel block 140 is provided with a texture. When braking is not required, the wheel block 140 is placed in the receiving portion 146 to press the interlocking member 145, and the interlocking member 145 triggers the brake switch 141 to unlock. When braking is required, the wheel block 140 is set at the front and rear positions of the wheels of the chassis 101, so as to play a braking role. At this time, the wheel block 140 is separated from the interlocking member 145, the wheel block 140 is not placed in the receiving portion 146, and the brake switch 141 remains locked. Such arrangement can achieve effective braking of the cleaning vehicle 1, ensure the safety of personnel and equipment, and is safe and reliable. In addition, the interlocking braking structure 143 is simple in structure.

[0092] In some embodiments, the interlocking brake structure 143 further includes a connecting member 148 fixed at the through hole portion 147 (eg, Fig.17 As shown in FIG. 1 , the interlocking member 145 is movably connected to the connecting member 148. The wheel block 140 is placed in the wheel block box 144, and the wheel block 140 presses the interlocking member 145, and the interlocking member 145 moves relative to the wheel block box 144. In this arrangement, the connecting member 148 plays a role in fixing the interlocking member 145, and the fixing stability is better.

[0093] In this embodiment, one of the connecting member 148 and the interlocking member 145 is provided with a connecting shaft 149, and the other is provided with a connecting hole 150. The connecting shaft 149 and the connecting hole 150 are clearance-matched, so that the interlocking member 145 is rotatably connected relative to the wheel block box 144 around the connecting shaft 149. In this embodiment, the connecting member 148 is provided with a connecting shaft 149, and the interlocking member 145 is provided with a connecting hole 150. Through the matching of the connecting shaft 149 and the connecting hole 150, the fixing stability is better. And this connection method has a simple structure.

[0094] In some embodiments, a counterweight block 151 (such as Fig.18 The wheel stopper 140 is placed in the wheel stop box 144, and the wheel stopper 140 presses against one end of the interlocking member 145 provided with a counterweight 151, and the interlocking member 145 provided with a counterweight 151 rotates relative to the wheel stop box 144. In this way, when the wheel stopper 140 presses against one end of the interlocking member 145 provided with a counterweight 151, the counterweight 151 is conducive to the wheel stopper 140 pressing against the interlocking member 145, so that the interlocking member 145 naturally hangs down, which is conducive to the rotation of the interlocking member 145.

[0095] In some embodiments, the interlocking member 145 includes a fan-shaped rotating piece, and the angle of the rotating piece is at least greater than 180 degrees. This arrangement ensures that when the wheel stop 140 presses against the interlocking member 145, both ends of the interlocking member 145 are abutted by the wheel stop 140, and the stability is better.

[0096] In some embodiments, the brake switch 141 includes a proximity switch 152, which is fixed to the connecting member 148 (eg, Fig.18 As shown). The proximity switch 152 includes a sensing end 153, which is arranged on a side of the connecting member 148 facing the interlocking member 145, and the sensing end 153 is at a distance from the interlocking member 145. When the interlocking member 145 moves relative to the wheel block box 144 to the sensing range of the sensing end 153, the proximity switch 152 is triggered to unlock. The proximity switch 152 can be operated without mechanical direct contact with the interlocking member 145, and the switch can be activated without mechanical contact or any pressure, thereby giving a control instruction to the control device 202. The proximity switch 152 has sensing performance, reliable operation, stable performance, fast frequency response, long service life, strong anti-interference ability, etc., and has the characteristics of waterproof, shockproof, corrosion resistance, etc. In some embodiments, the number and / or position of the brake switch 141 corresponds to the number and / or position of the interlocking member 145. Since the cleaning operation vehicle 1 is provided with two wheel blocks 140, two brake switches 141 and interlocking members 145 are provided to avoid omission.

[0097] In some embodiments, the wheel chock box 144 includes a wheel chock box body 154 and a support member 155 fixed to the wheel chock box body 154, the support member 155 supports the wheel chock box body 154; the wheel chock box body 154 is tilted relative to the surface of the chassis 101. In some embodiments, the wheel chock box body 154 includes a first side 156 and a second side 157, and the first side 156 and the second side 157 are arranged in the second direction X2. The first side 156 is arranged closer to the outer side of the chassis 101 relative to the second side 157, and the first side 156 is higher than the second side 157. Such an arrangement ensures that when the wheel chock 140 is inserted into the wheel chock box body 154, the side where the wheel chock 140 is inserted is higher, so as to prevent the wheel chock 140 from being separated from the wheel chock box body 154, and the stability is better.

[0098] In some embodiments, the wheel chock box 154 includes an opening 158 and a blocking portion 159, and the opening 158 and the blocking portion 159 are arranged opposite to each other. The opening 158 is arranged on the first side 156, and the opening 158 is connected to the receiving portion 146, so that the wheel chock 140 can be inserted into the receiving portion 146. The opening 158 is arranged on the first side 156, close to the outside of the chassis 101, so that it is convenient for the staff to insert. The blocking portion 159 is arranged on the second side 157, and the wheel chock 140 is placed in the receiving portion 146, and the blocking portion 159 blocks the wheel chock 140. Such an arrangement prevents the wheel chock 140 from detaching from the receiving portion 146 when it is inserted into the receiving portion 146, and the safety is better.

[0099] In some embodiments, the wheel chock box 144 includes a clamping portion 160, which is arranged at the top of the wheel chock box body 154. The clamping portion 160 extends from the first side 156 to the second side 157. The clamping portion 160 is bent relative to the wheel chock box body 154 from the edge of the wheel chock box body 154 to the inside of the receiving portion 146. The bending degree of the clamping portion 160 is adapted to the shape of the wheel chock member 140. Such a configuration ensures that when the wheel chock member 140 is inserted into the wheel chock box body 154, it is not easy to detach from the top or opening portion 158 of the wheel chock box body 154, and the stability is better. In some embodiments, a guide portion 161 is provided at the edge of the clamping portion 160 located on the first side 156, and the guide portion 161 is inclined from bottom to top and from the first side 156 to the second side 157. The guide portion 161 is used to guide the wheel chock member 140, so that the staff can insert the guide portion 161 into the receiving portion 146.

[0100] In some embodiments, the support member 155 includes a first support member 162 and a second support member 163, wherein the first support member 162 supports the first side 156, and the second support member 163 supports the second side 157, and the height of the first support member 162 is greater than the height of the second support member 163. This arrangement ensures that the height of the first side 156 of the wheel chock box 154 is greater than the height of the second side 157, and ensures that when the wheel chock 140 is inserted into the receiving portion 146, it is not easy to be separated from the opening portion 158, and the stability is better.

[0101] In some embodiments, the support member 155 includes a support body 164 and a first folded edge 165 and a second folded edge 166 disposed at both ends of the support body 164. The first folded edge 165 and the second folded edge 166 are located on the same side of the support body 164 and are bent toward the first side 156 relative to the second side 157. The first folded edge 165 is connected to the bottom of the wheel chock box 154, and the second folded edge 166 is connected to the chassis. In this embodiment, the support body 164 is a support plate, and the first folded edge 165 and the second folded edge 166 are formed by bending the support plate. The contact area between the first folded edge 165 and the second folded edge 166 is larger, and the fixing effect is better.

[0102] exist Figures 16 to 24In the illustrated embodiment, the wheel stop box 144 is provided as one. The wheel stop box 144 includes a partition 167, which divides the receiving portion 146 into a first receiving portion 168 and a second receiving portion 169. The wheel stop member 140 includes a first wheel stop member 170 and a second wheel stop member 171. The first wheel stop member 170 is placed in the first receiving portion 168, and the second wheel stop member 171 is placed in the second receiving portion 169. The interlocking member 145 includes a first interlocking member 172 and a second interlocking member 173. The first interlocking member 172 is provided at the bottom of the first receiving portion 168, and the first wheel stop member 170 is placed in the first receiving portion 168, and the first interlocking member 172 is pressed to rotate relative to the wheel stop box 144, and the first wheel stop member 170 triggers the first interlocking member 172 to unlock. The second interlocking member 173 is disposed on the inner side wall of the second receiving portion 169, and the second wheel stopper 171 is placed in the second receiving portion 169, pressing the second interlocking member 173 to rotate relative to the wheel stop box 144, and the second wheel stopper 171 triggers the second interlocking member 173 to unlock. In this way, the number of wheel stop boxes 144 can be reduced, and the upper space of the wheel stop boxes 144 can be effectively utilized.

[0103] In some other embodiments, the number of wheel stop boxes is set to a pair. The wheel stop box includes a first wheel stop box and a second wheel stop box; the interlocking member includes a first interlocking member and a second interlocking member; the first interlocking member is arranged at the bottom of the first wheel stop box, the first wheel stop member is placed in the first wheel stop box, the first interlocking member is pressed to rotate relative to the first wheel stop box, and the first wheel stop member triggers the first interlocking member to unlock; the second interlocking member is arranged at the bottom of the second wheel stop box, the second wheel stop member is placed in the second wheel stop box, the second interlocking member is pressed to rotate relative to the second wheel stop box, and the second wheel stop member triggers the second interlocking member to unlock.

[0104] The cleaning operation vehicle 1 is provided with an interlocking braking structure to realize an interlocking braking function, which can realize effective braking of the cleaning operation vehicle, ensure the safety of personnel and equipment, and be safe and reliable.

[0105] In actual application, in order to maintain a high vacuum degree of the vacuum tank 109, the vacuum degree adjustment method of the vacuum tank is used for adjustment. Fig.25 As shown, the vacuum degree adjustment method includes the following steps S1-S2.

[0106] Step S1, detecting the vacuum degree in the vacuum tank. In this process, a vacuum degree sensor, such as a negative pressure transmission, is used to detect the vacuum degree in the vacuum tank. This step detects the initial vacuum degree.

[0107] Step S2, controlling the vacuum pump to be turned on or off according to the vacuum degree in the vacuum tank. In this process, the control device controls the vacuum pump to be turned on or off according to the vacuum degree of the vacuum tank detected.

[0108] Specifically, step S2 includes steps S21-S22.

[0109] Step S21, when the vacuum degree in the vacuum tank is lower than the first vacuum degree, the vacuum pump is controlled to start, and the vacuum pump extracts the gas in the vacuum tank. In this process, the first vacuum degree can be 60%. When the vacuum degree in the vacuum tank is lower than 60%, it means that the vacuum degree in the vacuum tank is low at this time, and the dirt suction capacity is low. The control device controls the vacuum pump to start to extract the gas in the vacuum tank and increase the vacuum degree in the vacuum tank. In this way, the dirt suction capacity can be improved.

[0110] Step S22, when the vacuum degree in the vacuum tank is higher than the second vacuum degree, the vacuum pump is controlled to be turned off. In this process, the second vacuum degree can be 90%. When the vacuum degree in the vacuum tank is higher than 90%, it means that the vacuum degree in the vacuum tank is high at this time, and the dirt suction capacity is high, and the control device controls the vacuum pump to be turned off. In this way, a high vacuum degree can be ensured, and the service life of the vacuum pump can also be ensured.

[0111] In the above scheme, the first vacuum degree and the second vacuum degree are greater than the minimum suction vacuum degree of the vacuum tank, and the first vacuum degree is less than the second vacuum degree. In some embodiments, the minimum suction vacuum degree of the vacuum tank is in the range of 35% to 45%, and the preferred value is 40%. In some embodiments, the first vacuum degree and the second vacuum degree are in the range of 60% to 90%. Among them, the first vacuum degree is 60%. The second vacuum degree is 90%. Since the vacuum degree required by the vacuum tank is at least 40%, in order to ensure the operating efficiency and the efficient performance of the cleaning operation, the vacuum degree is set at 60%. On the other hand, in order to ensure the service life of the vacuum pump, the upper limit is set at 90%, so the vacuum degree is 60%-90%. In this way, by adjusting the vacuum degree in the vacuum tank, the first vacuum degree and the second vacuum degree are set to be greater than the minimum suction pressure value of the vacuum tank. Setting this range value ensures that the vacuum tank can realize the suction operation, and has a higher vacuum degree, improves work efficiency, and can also extend the service life.

[0112] In some embodiments, the cleaning operation vehicle also includes a plurality of actuators connected to the chassis. In this embodiment, the plurality of actuators may be a cleaning machine, an exhaust fan, and an air compressor. Among them, when one of the cleaning machine, the exhaust fan, and the air compressor is in a working state, the others are in a non-working state. Since the rotation speed of the vacuum pump is greater than the rotation speed of the cleaning machine, the exhaust fan, and the air compressor, if one of the cleaning machine, the exhaust fan, and the air compressor is in operation, the operating speed of the chassis needs to be considered. It is necessary to consider both the vacuum pump's vacuuming speed and the service life of the cleaning machine, the exhaust fan, and the air compressor.

[0113] See Fig.26 As shown, step S21 includes steps S211-S213. Among them,

[0114] Step S211: Detect the working state of one of the multiple executing devices. In this process, the operating power or speed of the executing device can be detected to determine the corresponding working state.

[0115] Step S212: adjusting the running speed of the chassis according to the working state of one of the execution devices. In this process, the control device can appropriately adjust the running speed of the chassis according to the current working state of the execution device.

[0116] Step S213, adjusting the speed of the vacuum pump according to the running speed of the chassis. In this process, after the control device properly adjusts the running speed of the chassis, the speed of the vacuum pump can be adjusted according to the adjusted running speed of the chassis. The vacuum pump is provided with a corresponding sensor for real-time detection of the speed of the vacuum pump.

[0117] When one of the cleaning machine, exhaust fan and air compressor is running, the running speed of the chassis must meet the speed requirements of the cleaning machine, exhaust fan and air compressor. It should not be too large or too small. If it is too large, it will burden the cleaning machine, exhaust fan and air compressor and shorten their life. If it is too small, it cannot be driven. Therefore, when the vacuum pump is running, it is necessary to first determine whether one of the cleaning machine, exhaust fan and air compressor is in working condition. If the above is in working condition, the running speed of the chassis can be adjusted appropriately to meet the speed requirements of the cleaning machine, exhaust fan and air compressor. If the above is not in working condition, the running speed of the chassis can be adjusted appropriately to adjust the speed of the vacuum pump and increase the vacuuming speed. Such a setting not only ensures that the vacuum tank has a high dirt absorption capacity, but also tries to avoid shortening the service life of the other actuators.

[0118] Further, step S212 includes: when one of the execution devices is in working state, adjusting the operating speed of the chassis to a first operating speed. Step S213 includes: when the operating speed of the chassis is at the first operating speed, adjusting the rotation speed of the vacuum pump to a first rotation speed. The first operating speed of the chassis corresponds to the first rotation speed of the vacuum pump. When one of the cleaning machine, the exhaust fan and the air compressor is in working state, the rotation speed of the vacuum pump is adjusted according to the operating speed of the chassis. Such a setting not only ensures that the vacuum tank has a high dirt suction capacity, but also tries to avoid shortening the service life of the above execution devices.

[0119] Further, step S212 includes: when one of the actuators is not in operation, adjusting the operating speed of the chassis to a second operating speed; wherein the second operating speed is equal to or greater than the first operating speed. Step S213 includes: when the operating speed of the chassis is at the second operating speed, adjusting the rotation speed of the vacuum pump to a second rotation speed; wherein the second rotation speed is equal to or greater than the first rotation speed. The second operating speed of the chassis corresponds to the second rotation speed of the vacuum pump. The first operating speed of the chassis may be the idle speed of the chassis, and the second operating speed may be the idle speed or above the idle speed. Idle speed refers to the engine running in neutral. One of the cleaning machine, the exhaust fan and the air compressor is not in operation, and the rotation speed of the vacuum pump is adjusted according to the operating speed of the chassis. With such a configuration, a high vacuuming speed is maintained and work efficiency is improved.

[0120] See also Fig. 27 As shown, accordingly, the vacuum degree adjustment device 2 of the vacuum tank is applied to the cleaning operation vehicle 1, and the vacuum degree adjustment device 2 includes a first detection device 201 and a control device 202. The first detection device 201 is used to detect the vacuum degree in the vacuum tank. In some embodiments, the first detection device 201 can be a vacuum sensor. In this embodiment, the vacuum sensor can be a negative pressure transmission. The control device 202 is connected to the first detection device 201, and the control device 202 controls the opening or closing of the vacuum pump according to the vacuum degree in the vacuum tank. Among them, when the vacuum degree in the vacuum tank is lower than the first vacuum degree, the control device controls the vacuum pump to open, and the vacuum pump extracts the gas in the vacuum tank. In this process, the first vacuum degree can be 60%. When the vacuum degree in the vacuum tank is lower than 60%, it means that the vacuum degree in the vacuum tank is low at this time, and the dirt suction capacity is low. The control device controls the vacuum pump to open to extract the gas in the vacuum tank and increase the vacuum degree in the vacuum tank. In this way, the dirt suction capacity can be improved. When the vacuum degree in the vacuum tank is higher than the second vacuum degree, the control device controls the vacuum pump to close. In this process, the second vacuum degree can be 90%. When the vacuum degree in the vacuum tank is higher than 90%, it means that the vacuum degree in the vacuum tank is high and the dirt suction capacity is high, and the control device controls the vacuum pump to shut down. This can ensure a high vacuum degree and also ensure the service life of the vacuum pump.

[0121] In the above scheme, the first vacuum degree and the second vacuum degree are both greater than the minimum suction vacuum degree of the vacuum tank, and the first vacuum degree is less than the second vacuum degree. In some embodiments, the minimum suction vacuum degree of the vacuum tank is in the range of 35% to 45%, and the preferred value is 40%. In some embodiments, the first vacuum degree and the second vacuum degree are in the range of 60% to 90%. Among them, the first vacuum degree is 60%. The second vacuum degree is 90%. Since the vacuum degree required by the vacuum tank is at least 40%, in order to ensure the operating efficiency and the efficient performance of the cleaning operation, the vacuum degree is set at 60%. On the other hand, in order to ensure the service life of the vacuum pump, the upper limit is set at 90%, so the vacuum degree is 60%-90%. In this way, by adjusting the vacuum degree in the vacuum tank, the first vacuum degree and the second vacuum degree are set to be greater than the minimum suction pressure value of the vacuum tank. Setting this range value ensures that the vacuum tank can realize the suction operation, and has a higher vacuum degree, improves the working efficiency, and can also extend the service life.

[0122] In some embodiments, the cleaning vehicle further includes a plurality of actuators 3 connected to the chassis; the plurality of actuators 3 include a cleaning machine, an exhaust fan, and an air compressor. Among them, when one of the cleaning machine, the exhaust fan, and the air compressor is in working state, the others are in non-working state. Since the rotation speed of the vacuum pump is greater than the rotation speed of the cleaning machine, the exhaust fan, and the air compressor, if one of the cleaning machine, the exhaust fan, and the air compressor is in operation, the operating speed of the chassis needs to be considered. It is necessary to consider both the vacuum pump's vacuuming speed and the service life of the cleaning machine, the exhaust fan, and the air compressor.

[0123] The vacuum degree regulating device 2 also includes a second detection device 203 and a regulating device 204. The second detection device 203 is used to detect the working state of one of the multiple actuators 3. The second detection device 203 can be a voltage sensor or a current sensor to detect the operating power of the actuator. The regulating device 204 is connected to the control device 202. The control device 202 controls the regulating device 204 according to the working state of one of the actuators 3 to adjust the running speed of the chassis. In this process, the control device can appropriately adjust the running speed of the chassis according to the current working state of the actuator. And the control device 202 controls the regulating device 204 according to the running speed of the chassis to adjust the speed of the vacuum pump. In this process, after the control device appropriately adjusts the running speed of the chassis, it can adjust the speed of the vacuum pump according to the adjusted running speed of the chassis. The vacuum pump is provided with a corresponding sensor for real-time detection of the speed of the vacuum pump.

[0124] When one of the cleaning machine, exhaust fan and air compressor is running, the running speed of the chassis must meet the speed requirements of the cleaning machine, exhaust fan and air compressor. It should not be too large or too small. If it is too large, it will burden the cleaning machine, exhaust fan and air compressor and shorten their life. If it is too small, it cannot be driven. Therefore, when the vacuum pump is running, it is necessary to first determine whether one of the cleaning machine, exhaust fan and air compressor is in working condition. If the above is in working condition, the running speed of the chassis can be adjusted appropriately to meet the speed requirements of the cleaning machine, exhaust fan and air compressor. If the above is not in working condition, the running speed of the chassis can be adjusted appropriately to adjust the speed of the vacuum pump and increase the vacuuming speed. Such a setting not only ensures that the vacuum tank has a high dirt absorption capacity, but also tries to avoid shortening the service life of the other actuators.

[0125] In some embodiments, the adjusting device 204 includes a first adjusting device and a second adjusting device, which are connected to the control device 202. In some embodiments, when one of the execution devices 3 is in working state, the control device 202 controls the first adjusting device to adjust the running speed of the chassis to the first running speed; and when the running speed of the chassis is at the first running speed, the control device 202 controls the second adjusting device to adjust the speed of the vacuum pump to the first speed. The first running speed of the chassis corresponds to the first speed of the vacuum pump. One of the cleaning machine, the exhaust fan and the air compressor is in working state, and the speed of the vacuum pump is adjusted according to the running speed of the chassis. Such a setting not only ensures that the vacuum tank has a high dirt absorption capacity, but also tries to avoid shortening the service life of the above execution devices.

[0126] In some other embodiments, when one of the actuators is in a non-working state, the control device controls the first regulating device to regulate the operating speed of the chassis to a second operating speed; and when the operating speed of the chassis is at the second operating speed, the control device controls the second regulating device to regulate the rotational speed of the vacuum pump to a second rotational speed; wherein the second operating speed is equal to or greater than the first operating speed; and the second rotational speed is equal to or greater than the first rotational speed. The second operating speed of the chassis corresponds to the second rotational speed of the vacuum pump. The first operating speed of the chassis may be the idle speed of the chassis, and the second operating speed may be the idle speed or above the idle speed. Idle speed refers to the engine running in neutral. One of the cleaning machine, the exhaust fan and the air compressor is in a non-working state, and the rotational speed of the vacuum pump is adjusted according to the operating speed of the chassis. With such a configuration, a high vacuuming speed is maintained, and work efficiency is improved.

[0127] The cleaning operation vehicle 1 includes the above-mentioned vacuum degree adjustment device 2 to ensure that the vacuum tank has a high dirt suction capacity and also to avoid shortening the service life of the above-mentioned execution device as much as possible.

[0128] The embodiment of the present application also provides a computer-readable storage medium, on which a computer program is stored, and when the program is executed by a processor, any of the above vacuum degree adjustment methods is implemented.
