DETAILED DESCRIPTION

[0030] The new energy cleaning vehicle 1 of the present application is described in detail below with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0031] Cleaning vehicles are used to clean the apron pipe network's bolt wells and valve wells, making them an essential component of the apron's oil supply network. In related technologies, these vehicles use diesel as a power source to drive their chassis. This generates a certain amount of carbon emissions during operation, especially when operating at idle speed, which poses a certain environmental pollution risk. Furthermore, diesel-powered chassis are noisy and contribute to noise pollution.

[0032] Based on this, this patent application provides a new energy cleaning vehicle 1 to solve the air pollution and noise pollution problems during the cleaning of apron pipe network bolt wells and apron pipe network valve wells. The apron pipe network bolt wells and apron pipe network valve wells can be generally referred to as ground wells.

[0033] Please refer to Figure 1 , Figure 1 This is a structural diagram of an embodiment of the new energy cleaning vehicle 1 of this application. Figure 1 As shown, the new energy cleaning vehicle 1 includes a cab 10, an electric chassis 20, a battery pack 30, and a cleaning assembly 4. The battery pack 30 and the cleaning assembly 4 are both arranged on the electric chassis 20. The battery pack 30 is electrically connected to the electric chassis 20 and the cleaning assembly 4 to supply power to the electric chassis 20 and the cleaning assembly 4. In this way, by supplying power to the electric chassis 20 and the cleaning assembly 4 through the battery pack 30, environmental pollution and noise generated during the operation of the cleaning vehicle 1 can be avoided. In addition, the start-stop control of the cleaning vehicle 1 is more flexible, making it more suitable for underground well cleaning operations that require frequent starts and stops.

[0034] Cleaning assembly 4 includes a suction device, a cleaning device, and a purge device. The suction device is used to remove impurities such as sewage, leaves, weeds, cotton wool, and sand from the apron pipe network well. The cleaning device is used to clean the fuel hydrant and fuel valve. The purge device promptly dries the cleaned oil storage well, fuel hydrant, and fuel valve. By including the suction device, cleaning device, and purge device, cleaning assembly 4 can clean the apron pipe network hydrant well and valve well.

[0035] The electric chassis 20 extends along a first direction X and a second direction Y in a horizontal plane, and the second direction Y is perpendicular to the first direction X. The first direction X may be a length direction of the electric chassis 20 , and the second direction Y may be a width direction of the electric chassis 20 .

[0036] The sewage suction device includes a vacuum tank 41, and the purge device includes a purge air tank 61. The vacuum tank 41 and the purge air tank 61 are both located on the electric chassis 20, and the electric chassis 20 provides support for the vacuum tank 41 and the purge air tank 61. The battery pack 30 and the purge air tank 61 are both located between the cab 10 and the vacuum tank 41. In this way, the battery pack 30 is located at the end of the electric chassis 20 close to the cab 10, and the vacuum tank 41 is located at the end of the electric chassis 20 away from the cab 10. Because the battery pack 30 is relatively heavy, arranging the battery pack 30 between the cab 10 and the vacuum tank 41 can prevent the center of gravity of the cleaning vehicle 1 from shifting backward, thereby improving the stability of the cleaning vehicle 1 during driving. By arranging the purge air storage tank 61 and the battery pack 30 along the second direction Y, space in the length direction of the electric chassis 20 can be saved. The cleaning device includes a clean water tank 51, which is provided on the electric chassis 20. The clean water tank 51 and the vacuum tank 41 are arranged along the second direction Y. The space in the width direction of the electric chassis 20 can be fully utilized, making the new energy cleaning vehicle 1 compact.

[0037] In the embodiment of the present application, the battery pack 30 includes multiple battery packs 31, which are symmetrically arranged about the central axis of the electric chassis 20 in the second direction Y. The battery pack 30 is composed of multiple battery packs 31. Given the considerable weight of the battery pack 30 itself, its mounting position on the electric chassis 20 significantly impacts the overall stability. However, arranging the multiple battery packs 31 symmetrically about the central axis of the electric chassis 20 in the second direction Y allows the weight of the battery pack 30 to be evenly distributed on both sides of the central axis. This symmetrical weight distribution effectively prevents the center of gravity of the electric chassis 20 from shifting due to excessive weight on one side, ensuring that the center of gravity of the entire electric chassis 20 remains in a relatively stable central area. Whether starting, accelerating, decelerating, or turning, a stable center of gravity reduces vehicle body sway and tilt, improving driving stability and safety. It also reduces the additional damage to the chassis structure and related components caused by an unstable center of gravity, thereby extending the service life of the electric chassis 20.

[0038] exist Figure 1 In the embodiment shown, the battery pack 30 includes five battery packs 31. Figure 2 , Figure 2 Shown is a structural schematic diagram of another embodiment of the new energy cleaning vehicle 1 of the present application. Figure 2 The embodiment shown is Figure 1 The embodiments shown are basically the same. The difference is that Figure 2 In the embodiment shown, the battery pack 30 includes three battery packs 31. In combination with the cleaning efficiency of the new energy cleaning vehicle 1 when cleaning a well and the distance the new energy cleaning vehicle 1 needs to move, the energy consumption of the electric chassis 20 and the energy consumption of the cleaning assembly 4 are determined.

[0039] This application proposes two vehicle models: a long-range vehicle with a battery pack 30 comprising five battery packs 31, and a standard-range vehicle with a battery pack comprising three battery packs 31. The long-range vehicle's battery capacity allows the new energy cleaning vehicle 1 to operate for two days, travel 20 km per day, and complete 60 well-washing operations per day. The standard-range vehicle's battery capacity allows the new energy cleaning vehicle 1 to operate for two days, travel 20 km, and complete 60 well-washing operations. In other embodiments, the number of battery packs 31 in the battery pack 30 can be other numbers, and this application does not limit this.

[0040] Please refer to Figure 3 , Figure 3 for Figure 2 The schematic diagram of the structure of the electric chassis 20 and battery pack 30 of the new energy cleaning vehicle 1 is shown. Figure 3In the illustrated embodiment, the electric chassis 20 extends along a first direction X and a second direction Y within a horizontal plane, with the second direction Y being perpendicular to the first direction X. In the first direction X, the battery pack 30 is located at one end of the electric chassis 20 near the cab 10 of the new energy cleaning vehicle 1. This prevents the center of gravity of the new energy cleaning vehicle 1 from shifting rearward, improving its stability during operation.

[0041] The electric chassis 20 includes two chassis longitudinal beams 21 and a plurality of chassis cross beams 22 . The two chassis longitudinal beams 21 extend along a first direction X, and the plurality of chassis cross beams 22 extend along a second direction Y and are arranged between the two chassis longitudinal beams 21 along the first direction X. This enhances structural stability.

[0042] exist Figure 3 In the embodiment shown, the three battery packs 31 are arranged along the second direction Y and are all located above the electric chassis 20. The length of the three battery packs 31 along the first direction X is greater than the length of the three battery packs 31 along the second direction Y.

[0043] The three battery packs 31 are arranged along the second direction Y, and the length of the three battery packs 31 along the first direction X is greater than the length of the three battery packs 31 along the second direction Y. This can avoid the problem of the three battery packs 31 being too wide in the width direction (second direction Y) of the electric chassis 20 after being arranged, and avoid the problem of excessive width. The three battery packs 31 are all located above the electric chassis 20. Because the number of the three battery packs 31 is not too large, and the three battery packs 31 are not stacked in the height direction of the new energy cleaning vehicle 1, the three battery packs 31 can be placed above the electric chassis 20, utilizing the space above the electric chassis 20. Placing the three battery packs 31 above the electric chassis 20 also facilitates the inspection and maintenance of a single battery pack 31.

[0044] Please refer to Figure 4 , Figure 4 for Figure 1 The schematic diagram of the structure of the electric chassis 20 and battery pack 30 of the new energy cleaning vehicle 1 is shown. Figure 4 In the illustrated embodiment, the battery pack 30 includes five battery packs 31. Two of the battery packs 31 are located on either side of the electric chassis 20 in the second direction Y, and both are located below the electric chassis 20. The length of the two battery packs 31 along the first direction X is greater than the length of the two battery packs 31 along the second direction Y. The other three battery packs 31 are arranged along the third direction Z and are all located in the middle of the second direction Y above the electric chassis 20. The length of the three battery packs 31 along the first direction X is less than the length of the two battery packs 31 along the second direction Y. The third direction Z represents the height of the new energy cleaning vehicle 1.

[0045] Because five batteries are a relatively large number, two battery packs 31 are placed below the electric chassis 20, utilizing the space below the electric chassis 20 and conserving space above it. The length of the two battery packs 31 along the first direction X is greater than the length of the two battery packs 31 along the second direction Y. The longer sides of the battery packs 31 extend parallel to the length of the electric chassis 20, while the shorter sides extend parallel to the width of the electric chassis 20. This minimizes the width between the two battery packs 31 after arrangement. The two battery packs 31 are placed on either side of the electric chassis 20 in the second direction Y, with no battery pack 31 positioned between them. This facilitates access to the battery packs 31 on either side of the electric chassis 20 in the second direction Y.

[0046] By arranging the other three battery packs 31 along the third direction Z, which represents the height of the new energy cleaning vehicle 1, space above the electric chassis 20 can be saved, leaving room for cleaning components 4 such as the purge air tank 61. By positioning the other three battery packs 31 in the middle of the second direction Y above the electric chassis 20, the center of gravity of the stacked battery packs 31 is positioned at the center of the electric chassis 20 in the second direction Y. By ensuring that the length of the three battery packs 31 in the first direction X is shorter than the length of the two battery packs 31 in the second direction Y, more space can be reserved along the length of the electric chassis 20.

[0047] Please refer to Figure 5 , Figure 5 FIG. 1 is a structural diagram of an electric chassis 20 and a battery pack 30 shown in another embodiment. Figure 5 In the illustrated embodiment, the battery pack 30 includes five battery packs 31 . Figure 5 The embodiment shown is Figure 4 The embodiment shown is basically the same, except that the arrangement of the five battery packs 31 on the electric chassis 20 is different. Figure 5 In the illustrated embodiment, the five battery packs 31 are all located above the electric chassis 20, and the length of the five battery packs 31 along the first direction X is less than the length of the five battery packs 31 along the second direction Y. The five battery packs 31 are divided into three layers in the third direction Z. The two layers closest to the electric chassis 20 each include two battery packs 31, and the two battery packs 31 extend along the second direction Y. The battery packs 31 in the layer farther from the electric chassis 20 are located in the middle of the electric chassis 20 in the second direction Y. The third direction Z represents the height of the new energy cleaning vehicle 1.

[0048] Please refer to Figure 6 , Figure 6 FIG. 1 is a structural diagram of an electric chassis 20 and a battery pack 30 shown in another embodiment. Figure 6 In the illustrated embodiment, the battery pack 30 includes five battery packs 31 . Figure 6 The embodiment shown is Figure 4 The embodiment shown is basically the same, except that the arrangement of the five battery packs 31 on the electric chassis 20 is different. Figure 6 In the illustrated embodiment, the length of the five battery packs 31 along the first direction X is greater than the length of the five battery packs 31 along the second direction Y. Three battery packs 31 are located below the electric chassis 20 and arranged along the second direction Y. Two battery packs 31 are arranged along the third direction Z and are both located above the electric chassis 20 in the middle of the second direction Y. The third direction Z represents the height of the new energy cleaning vehicle 1.

[0049] It is understood that the number of battery packs 31 included in the battery assembly 30 can be specifically designed based on the daily power consumption of the new energy cleaning vehicle 1. The arrangement of the battery packs 31 on the electric chassis can be specifically designed after the number of battery packs 31 is determined, taking into account the size of the battery packs 31, the size of the electric chassis 20, and the occupied area of ​​the cleaning assembly 4.

[0050] Please also refer to Figure 1 and Figure 2 ,like Figure 1 and Figure 2 As shown, the battery pack 30 further includes a plurality of protective covers, each of which covers at least one battery pack 31. Figure 1 In the embodiment shown, there are three protective covers. The two battery packs 31 below the electric chassis 20 each occupy one protective cover, and the three battery packs 31 above the electric chassis 20 share one protective cover. Figure 2 In the illustrated embodiment, there are three protective covers, each of which protects one battery pack 31 .

[0051] Please refer again Figure 1 and Figure 2 ,exist Figure 1 and Figure 2 In the illustrated embodiment, the new energy cleaning vehicle 1 further includes a frame 70 that protrudes upward from the electric chassis 20. The frame 70 extends along a first direction X and is located between the cab 10 and the vacuum tank 41. This not only facilitates the use of the space between the cab 10 and the vacuum tank 41, but also the frame 70 is located relatively close to the cab 10, making it easier for the driver to use the frame as a reference when parking the new energy cleaning vehicle 1. Once parked, the frame is positioned near the well to be cleaned. The frame and battery pack 30 are arranged in a second direction Y, with the frame 70 and the purge air tank 61 located on either side of the battery pack 30 in the second direction Y. This allows the space in the second direction Y of the electric chassis 20 to be utilized.

[0052] The sewage suction device also includes a vacuum pump 42, a sewage suction hose and a sewage suction gun 44. In the second direction Y, the vacuum pump 42 is located between the frame 70 and the purge air storage barrel 61. In this way, it is not only convenient to utilize the space of the electric chassis 20, but also the vacuum pump 42 is close to the vacuum tank 41 and the frame 70, which can save connecting pipes.

[0053] A vacuum port 411 and a first sewage suction port 412 are provided at the top of the vacuum tank 41. A vacuum pump 42 is connected to the vacuum port 411 for evacuating the vacuum tank 41. The two ends of a sewage suction hose are connected to a sewage suction gun 44 and the first sewage suction port 412, respectively. When the sewage suction device is operating, the vacuum pump 42 draws gas from the vacuum tank 41, creating a certain vacuum within the vacuum tank 41. The pressure difference between the inside and outside of the vacuum tank 41 is then used to draw sewage from outside the vacuum tank 41 into the vacuum tank 41. Because the vacuum pump 42 does not directly pump water, it is less sensitive to solid impurities in the sewage.

[0054] The sewage suction hose is located on the inner side of the frame 70 in the second direction Y, while the sewage suction gun 44 is movably mounted on the frame 70 and positioned outside of the frame 70 in the second direction Y. This arrangement prevents interference between the sewage suction hose and the sewage suction gun 44, respectively, by positioning the sewage suction hose and the sewage suction gun 44 on opposite sides of the frame 70 in the second direction Y. Furthermore, the sewage suction gun 44 is movably mounted on the frame 70 and positioned outside of the frame 70 in the second direction Y. This makes the sewage suction gun 44 easily accessible and convenient for operators. When sewage suction is needed, operators remove the sewage suction gun 44 from the frame 70, insert it into the well to be cleaned, and suction the sewage in the well. After the suction is complete, the sewage suction gun 44 is returned to the frame 70. The sewage suction hose is coiled in a disc shape, allowing it to extend when the distance between the cleaning vehicle 1 and the frame 70 is large, enhancing operational flexibility.

[0055] A second sewage suction port 413 is also provided at the top of the vacuum tank 41. The diameter of the second sewage suction port 413 is larger than the diameter of the first sewage suction port 412. The new energy cleaning vehicle 1 also includes a sewage suction pipe 414, which is connected to the second sewage suction port 413 and extends downward along the second direction Y, away from the end of the frame 70. In this way, by providing the second sewage suction port 413, the diameter of the second sewage suction port 413 is larger than the diameter of the first sewage suction port 412. When there is a large amount of debris in the well to be sucked out, the sewage can be sucked out through the second sewage suction port 413. And because the diameter of the second sewage suction port 413 is larger than the diameter of the first sewage suction port 412, sucking out sewage through the second sewage suction port 413 can improve the efficiency of sewage suction, which is suitable for cleaning wells with a large amount of sewage. The new energy cleaning vehicle 1 includes a sewage suction splicing pipe. When sucking sewage through the second sewage suction port 413, the sewage suction splicing pipe and the sewage suction pipe 414 can be connected, and the sewage suction splicing pipe can be extended into the place to be sucked to suck sewage. After the sewage suction is completed, the sewage suction splicing pipe can be removed from the sewage suction pipe 414 and stored.

[0056] The cleaning device also includes a cleaning pump 52, a cleaning hose, and a cleaning gun 54. The cleaning pump 52 is assembled at the bottom of the electric chassis 20 and is close to the frame 70. The cleaning pump 52 is connected to the clean water tank 51 and the cleaning hose. The cleaning hose is connected to the cleaning gun 54. The cleaning hose is located on the inner side of the frame 70 in the second direction Y. The cleaning gun 54 is movably mounted on the frame 70 and is located on the outer side of the frame 70 in the second direction Y.

[0057] By assembling the cleaning pump 52 at the bottom of the electric chassis 20 and close to the frame 70, the cleaning pump 52 can be made closer to both the frame 70 and the clean water tank, making it easier for the cleaning pump 52 to connect to the clean water tank and the cleaning hose located on the inside of the frame 70. When the cleaning pump 52 is working, the clean water in the clean water tank is pressurized and then transported to the cleaning gun 54 through the cleaning hose, and the ground well is flushed with high-pressure water flow. The cleaning hose is disc-shaped and can be extended when the distance between the cleaning vehicle 1 and the frame 70 is large, thereby improving the flexibility of operation. By positioning the cleaning hose on the inside of the second direction Y of the frame 70, the cleaning gun 54 can be movably arranged on the frame 70 and on the outside of the second direction Y of the frame 70. This makes it easier for staff to take and place the cleaning gun 54, and also avoids mutual interference between the cleaning gun 54 and the cleaning hose.

[0058] The purging device also includes a purging hose and a purging gun 63. The two ends of the purging hose are connected to the purging gas storage tank 61 and the purging gun 63, respectively. The high-pressure gas in the purging gas storage tank 61 is output through the purging hose and the purging gun 63 to dry the cleaned well. The purging hose is located on the inner side of the frame 70 in the second direction Y, and the purging gun 63 is movably mounted on the frame 70 and located on the outer side of the frame 70 in the second direction Y. The purging hose is disc-shaped and can be extended when the distance between the cleaning vehicle 1 and the frame 70 is large, thereby improving operational flexibility. By positioning the purging hose on the inner side of the frame 70 in the second direction Y and the purging gun 63 on the outer side of the frame 70 in the second direction Y, it is convenient for staff to remove and place the purging gun 63, and it can also prevent interference between the purging gun 63 and the purging hose.

[0059] The new energy cleaning vehicle 1 also includes an air pump 64 and a brake air tank 65. The air pump 64 is arranged at the bottom of the electric chassis 20, and the air pump 64 is connected to the purge air tank 61 and the brake air tank 65 respectively to supply air to the purge air tank 61 and the brake air tank 65. The air in the purge air tank 61 is used for the purge component, and the air in the brake air tank 65 is used for air braking when the chassis brakes. In this application, by setting an air pump 64, the air pump 64 is connected to both the brake air tank 65 and the purge air tank 61, and the air pump 64 supplies air to both the brake air tank 65 and the purge air tank 61, the number of air pumps 64 can be saved.

[0060] In the embodiment of the present application, the purge air tank 61 is vertically arranged on the electric chassis 20. In this way, the area of ​​the electric chassis 20 occupied by the purge air tank 61 can be reduced, making the top space of the electric chassis 20 more compact. In the embodiment of the present application, the brake air tank 65 is horizontally arranged below the electric chassis 20. With this arrangement, the brake air tank 65 is close to the wheel, making it easier for the brake air tank 65 to supply air to the brake assembly of the wheel. The brake air tank 65 is arranged below the electric chassis 20 to reduce the space occupied above the electric chassis 20. The brake air tank 65 is placed horizontally to prevent the brake air tank 65 from touching the ground.

[0061] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the power supply of a new energy cleaning vehicle 1 shown in one embodiment of the present application. Figure 7 As shown, the new energy cleaning vehicle 1 also includes a power battery 32 and a low-voltage battery 33. Both the power battery 32 and the low-voltage battery 33 are located on the electric chassis 20. The battery pack 30 is connected to the power battery 32 and the low-voltage battery 33 to provide power to the power battery 32 and the low-voltage battery 33. The power battery 32 is connected to the electric chassis 20 and the cleaning component 4 to provide power to the electric chassis 20 and the driving components 34 of the cleaning component 4. The low-voltage battery 33 is connected to the electric chassis 20 and the cleaning component 4 to provide power to the control components 35 in the electric chassis 20 and the cleaning component 4.

[0062] The drive components 34 of the cleaning assembly 4 include, but are not limited to, a vacuum pump 42 and a cleaning pump 52, which are powered by the power battery 32. The drive components 34 of the electric chassis 20 include, but are not limited to, a drive motor, etc., which are powered by the power battery 32. The control components 35 of the cleaning assembly 4 include, but are not limited to, a controller for the vacuum pump 42 and a controller for the cleaning pump 52. The control components 35 of the electric chassis 20 include, but are not limited to, the steering control system, battery control system, acceleration and deceleration control system, etc. of the cleaning vehicle 1.

[0063] The driving component 34 of the cleaning component 4 and the driving component 34 of the electric chassis 20 share a power battery 32, and the control component 35 of the cleaning component 4 and the control component 35 of the electric chassis 20 share a low-voltage battery 33, which can reduce the number of power batteries 32 and low-voltage batteries 33, save the space occupied by the power batteries 32 and low-voltage batteries 33, and reduce costs.

[0064] In the embodiment of the present application, the electric chassis 20 includes a power take-off, the sewage suction device includes a vacuum pump 42, and the new energy cleaning vehicle 1 also includes a controller, which is connected to both the power take-off and the vacuum pump 42, and is used to control the vacuum pump 42 to start after obtaining the signal that the power take-off is engaged. After the driver parks the cleaning vehicle 1, the power take-off is engaged to prevent the cleaning vehicle 1 from moving and then clean the ground well. Because the sewage suction device adopts the vacuum suction principle, it takes a certain amount of time to reduce the vacuum degree in the vacuum tank 41. If the driver holds the sewage suction gun 44 and then controls the operation of the vacuum pump 42, a waiting time will be generated. In this patent application, when the controller detects that the power take-off is engaged, it directly controls the vacuum pump 42 to start and evacuate the vacuum tank 41, which can avoid waiting for the staff and improve the efficiency of sewage suction.

[0065] Please also refer to Figure 1 and Figure 8 , Figure 8 for Figure 1 The structural diagram of the new energy cleaning vehicle from another perspective is shown in FIG. Figure 1 and Figure 8 As shown, the cleaning device includes a first clean water tank 511, a second clean water tank 512, and a connecting pipe. The first clean water tank 511 and the second clean water tank 512 are located on either side of the vacuum tank 41 in the second direction Y. The connecting pipe is located in the vacuum tank 41 and connects the first clean water tank 511 and the second clean water tank 512. The first direction X and the second direction Y are perpendicular. Thus, the clean water tank 51 is provided on both sides of the vacuum tank 41 in the second direction Y. This avoids the situation where the center of gravity of the cleaning vehicle 1 is shifted by only providing the clean water tank 51 on one side of the vacuum tank 41, thereby ensuring that the weight of the electric chassis 20 on both sides of the second direction Y is relatively balanced. The connecting pipe connects the first clean water tank 511 and the second clean water tank 512, ensuring that the water levels in the first clean water tank 511 and the second clean water tank 512 are the same. If the first clean water tank 511 and the second clean water tank 512 are of the same shape and size, the weight of the water on both sides of the vacuum tank 41 in the second direction Y is the same. During use, the water in the first clean water tank 511 and the water in the second clean water tank 512 will decrease synchronously to maintain the dynamic balance of the weight of the clean water on both sides of the vacuum tank 41 in the second direction Y.

[0066] In the embodiment of the present application, the vacuum tank 41 is symmetrically arranged about the central axis of the second direction Y of the electric chassis 20, and the first clean water tank 511 and the second clean water tank 512 are symmetrically arranged about the central axis of the vacuum tank 41 in the second direction Y. This symmetrical weight distribution method can effectively avoid the problem of the center of gravity of the electric chassis 20 being shifted due to excessive weight on one side, so that the center of gravity of the entire electric chassis 20 always remains in a relatively stable central area.

[0067] In the embodiment of the present application, at least one of the first clean water tank 511 and the second clean water tank 512 is provided with an observation window 516. The observation window 516 is provided on a side wall of the first clean water tank 511 and / or the second clean water tank 512 in the first direction X. By providing the observation window 516, the height of the clean water in the first clean water tank 511 and the second clean water tank 512 can be intuitively obtained.

[0068] In the embodiment of the present application, the first direction X is the direction of travel of the cleaning vehicle 1, the first clean water tank 511 is located on the left side of the second direction Y of the vacuum tank 41, and the second clean water tank 512 is located on the right side of the second direction Y of the vacuum tank 41. The frame 70 of the new energy cleaning vehicle 1 is also located on the left side of the second direction Y of the vacuum tank 41. The frame 70 and the first cleaning tank are both located on the left side of the direction of travel of the cleaning vehicle 1. By setting the frame 70 on the left side of the direction of travel of the cleaning vehicle 1, it is more in line with the staff's operating habits when they take the suction gun 44, cleaning gun 54 and purge gun 63 from the frame 70. Because the frame 70 has been placed in front of the first clean water tank 511, if the observation window 516 is set on the side wall of the first clean water tank 511 in the first direction X, the frame 70 may block the observation window 516. Therefore, the observation window 516 is opened in the second clean water tank 512.

[0069] In the embodiment of the present application, at least one of the first clean water tank 511 and the second clean water tank 512 is provided with a water inlet 513, and the water inlet 513 is provided on the side wall of the first clean water tank 511 and / or the second clean water tank 512 in the second direction Y. By providing the water inlet 513, it is convenient to fill water into the first clean water tank 511 and the second clean water tank 512. In some embodiments, the opening size of the water inlet 513 is adapted to the size of the fire hydrant, supporting direct water intake from the fire hydrant. In the embodiment of the present application, the water inlet 513 is provided on the side wall of the second clean water tank 512 in the second direction Y, which is more in line with the driving habit and parking habit of the cleaning vehicle 1 that drives on the right, and is convenient for filling water into the first clean water tank 511 and the second clean water tank 512 of the cleaning vehicle 1 from the right side of the parking position of the cleaning vehicle 1 after the cleaning vehicle 1 is parked.

[0070] At least one of the first clean water tank 511 and the second clean water tank 512 is provided with a water outlet, which is provided at the bottom of the first clean water tank 511 and / or the second clean water tank 512. The provision of the water outlet facilitates draining the clean water in the first clean water tank 511 and the second clean water tank 512 when the cleaning vehicle 1 is about to be idle for a period of time, or facilitates draining the water in the first clean water tank 511 and the second clean water tank 512 when cleaning.

[0071] At least one of the first clean water tank 511 and the second clean water tank 512 is provided with a first maintenance manhole 514, which is disposed on a side wall of the first clean water tank 511 and / or the second clean water tank 512 in the second direction Y. If the first clean water tank 511 is provided with the first maintenance manhole 514, it is convenient to inspect the first clean water tank 511. If the second clean water tank 512 is provided with the first maintenance manhole 514, it is convenient to inspect the second clean water tank 512.

[0072] In some embodiments, a second inspection manhole 515 is provided on the top of the vacuum tank 41 to facilitate inspection and maintenance of the vacuum tank 41. In some embodiments, a sewage outlet is provided at the bottom of the vacuum tank 41 to facilitate the drainage of sewage or other pollutants in the vacuum tank 41 by parking the cleaning vehicle 1 in a place where sewage can be drained after the sewage extraction operation is completed.

[0073] exist Figure 6 In the illustrated embodiment, the lengths of the first and second clean water tanks 511, 512 are shorter than the length of the vacuum tank 41 in the first direction X. Because there are two clean water tanks 51, given the same water demand, the lengths of the first and second clean water tanks 511, 512 in the first direction X do not need to be excessively long to meet the clean water demand. Thus, the areas on both sides of the vacuum tank 41 in the second direction Y not occupied by the first and second clean water tanks 511, 512 can be used to house other components, such as storage areas for tools or parts.

[0074] exist Figure 6 In the illustrated embodiment, one end of the first clean water tank 511 , one end of the second clean water tank 512 and one end of the vacuum tank 41 are flush in the first direction X. In this way, the space utilization of the electric chassis 20 can be improved and the aesthetics of the new energy cleaning vehicle 1 can be enhanced.

[0075] In the embodiment of the present application, the first clean water tank 511 and the second clean water tank 512 are symmetrically arranged about the central axis of the vacuum tank 41 in the second direction Y. This effectively avoids the problem of the center of gravity of the electric chassis 20 shifting due to excessive weight on one side, so that the center of gravity of the entire electric chassis 20 always remains in a relatively stable central area.

[0076] exist Figure 6In the illustrated embodiment, the cleaning assembly 4 further includes an emergency exhaust device and a storage box 80, wherein the emergency exhaust device is disposed within the storage box 80. When a worker needs to go down the well, the emergency exhaust device can remove toxic and harmful gases from the well, eliminate safety hazards associated with downhole operations, and prevent poisoning incidents. Because the emergency exhaust device is only used when a worker needs to go down the well, its frequency of use is lower than that of the suction device, cleaning device, and purge device. Therefore, by providing the storage box 80, the emergency exhaust device can be stored, reducing the surface space occupied by the electric chassis 20 and enhancing the aesthetics. When exhaust operations are required, the emergency exhaust device can be removed from the storage box for exhaust operations.

[0077] The emergency exhaust system consists of an exhaust fan, an exhaust pipe, and an exhaust duct. When exhaust is required, the exhaust duct should be connected to the exhaust fan's air inlet and extended into the ground well. The exhaust duct should be connected to the exhaust fan's air outlet and extended vertically upward into the air. Because the ground well may contain toxic and harmful gases, the exhaust duct outlet should be at least two meters above the ground to prevent the release of toxic and harmful gases that could harm human health.

[0078] The holding box 80 includes a first holding box 81 and a second holding box 82. The first holding box 81, the second holding box 82, and the first clean water tank 511 are located on the same side of the vacuum tank 41 in the second direction Y. The first holding box 81 and the first clean water tank 511 are arranged along the first direction X, and the exhaust fan is located within the first holding box 81. This fully utilizes the space on one side of the vacuum tank 41 in the second direction Y. The height of the first holding box 81 is similar to that of the first clean water tank 511. The first holding box 81 and the first clean water tank 511 are arranged along the first direction X, creating a neat and reasonable layout.

[0079] The second storage box 82 is located on top of the first storage box 81 and the first clean water tank 511, and the exhaust and suction pipes are located within the second storage box 82. As a result, the second storage box 82 is relatively long, making it convenient for accommodating long objects such as the exhaust and suction pipes. The exhaust pipe, in particular, is not only long but also requires a certain degree of rigidity to allow it to extend vertically upwards for more than two meters.

[0080] The first storage box 81 includes a storage box body 80 and a box door movably connected to the storage box body 80. A movable member connected to the exhaust fan is provided in the storage box 80. The movable member can be moved relative to the storage box body 80 to the outside of the first storage box 81 to drive the exhaust fan to move outside the first storage box 81. In this way, by providing a movable member to drive the exhaust fan to move outside the first storage box 81, it is convenient to assemble the exhaust pipe and exhaust pipe outside the first storage box 81, and it is convenient to extend the exhaust pipe into the interior of the well and the exhaust pipe into the air. When the movable member drives the exhaust fan to move outside the first box, the movable member can also provide support for the exhaust fan, eliminating the need to carry the exhaust fan and improving the efficiency of the exhaust. In some embodiments, the movable member includes a fixed portion and a sliding portion. The sliding portion is slidably connected relative to the fixed portion along the second direction Y. The fixed portion is fixed to the bottom wall of the first storage box 81, and the exhaust fan is fixed to the sliding portion. When air extraction is required, the sliding part slides relative to the fixed part from the inside of the first containing box 81 to the outside of the first containing box 81 to drive the exhaust fan to move outside the first containing box 81. When air extraction is not required, the sliding part is fixedly connected to the fixed part, and the exhaust fan is stored in the first containing box 81.

[0081] In this embodiment of the present application, the cleaning assembly 4 also includes an emergency rescue device, and the storage box 80 also includes a third storage box 83. The third storage box 83 and the second clean water tank 512 are arranged along the first direction X, and the emergency rescue device is located within the third storage box 83. Thus, the third storage box 83, along with the first storage box 81 and the second storage box 82, are located on either side of the vacuum tank 41 in the second direction Y. The third storage box 83 and the second clean water tank 512 are arranged along the first direction X, utilizing the space behind the second clean water tank 512 in the first direction X. This facilitates full utilization of the space in the electric chassis 20, resulting in a compact structure for the new energy cleaning vehicle 1.

[0082] The emergency rescue device can be a triangular rescue frame, which is used for emergency rescue during underground operations. In the event of a critical situation, 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.

[0083] The storage box 80 also includes a fourth storage box 84 and a fifth storage box 85. Both are located at the bottom of the third storage box 83. The fourth storage box 84 and the second clean water tank 512 are arranged along the first direction X, for storing tools, utilizing the space behind the second clean water tank 512 in the first direction X. The fifth storage box 85 is also located at the bottom of the second clean water tank 512. This allows the fifth storage box 85 to be longer and accommodate a sewage splicing pipe. In some embodiments, the fifth storage box 85 is two meters long and contains three sewage splicing pipes. The spliced ​​sewage splicing pipes are connected to the sewage suction pipe 414, which allows for sewage suction from deeper wells through the second sewage suction port 413. After the sewage is sucked out, the splicing pipes are separated from the sewage suction pipe 414 and from each other, and then placed in the fifth storage box 85, which improves the aesthetics and practicality of the new energy cleaning vehicle 1.

[0084] like Figure 1 As shown, an embodiment of the present application provides a new energy cleaning vehicle 1, including a cab 10, an electric chassis 20, a battery pack 30 and a cleaning component 4. The battery pack 30 and the cleaning component 4 are both arranged on the electric chassis 20. The battery pack 30 is electrically connected to the electric chassis 20 and the cleaning component 4 to supply power to the electric chassis 20 and the cleaning component 4. The battery pack 30 is arranged on the side of the electric chassis 20 close to the cab 10, and the vacuum tank 41 is located on the side of the electric chassis 20 away from the cab 10.
