Description

Technical Field

[0001] The present application relates to the technical field of emergency drainage, and in particular to a new energy, high-flow, intelligent drainage vehicle for emergency rescue and disaster relief. Background Art

[0002] Large-flow drainage vehicles are modified on various pickup trucks, light trucks and heavy truck chassis. They are mobile and flexible, have large displacement, can carry a large amount of equipment and materials, and are easy to operate, and are favored by the market.

[0003] At present, with the popularization of new energy, many pickup trucks or heavy trucks use new energy, which is driven by batteries to travel, and the battery capacity of the body is large, which can save the installation of diesel generator sets in the car body of most heavy-duty and light-duty drainage vehicles. The diesel generator sets are directly discharged through their own batteries to provide power to multiple portable drainage electric pumps.

[0004] However, multiple portable drainage electric pumps need to be taken out one by one by manpower and placed under the water surface that needs to be drained. In the meantime, the circuits and water hoses of the portable drainage electric pumps must be connected, which consumes a lot of manpower and is troublesome to put in and take out. Summary of the Invention

[0005] In order to facilitate the placement of a portable drainage electric pump under the water surface that needs to be drained, save manpower and facilitate the connection of circuits and water hoses, the present application provides a new energy, large-flow emergency rescue and disaster relief intelligent drainage vehicle.

[0006] The present application provides a new energy, large-flow, intelligent drainage vehicle for emergency rescue and disaster relief, which adopts the following technical solution: it includes a vehicle body, an accommodating chamber for storing water hoses and drainage pumps, a new energy battery at the bottom to supply electricity to the entire vehicle, and a rotating drum located on both sides of the vehicle body rotates in the accommodating chamber; a compartment door; a door rotatably arranged at the rear of the vehicle body to seal the accommodating chamber; a mobile cart, which is placed in the accommodating chamber and can be remotely controlled, and the mobile cart has a battery and a drainage pump inside, the drainage pump is electrically connected to the battery, and the mobile cart has a water inlet pipe connected to the water inlet end of the drainage pump; a water hose is sleeved on the drum, and the end of the water hose away from the drum is connected to the water outlet end of the drainage pump, and the end of the drum rotatably connected to the vehicle body passes through the side wall of the vehicle body to form a water outlet, and the drum is used to discharge the water in the water hose out of the vehicle body.

[0007] By adopting the above technical solution, when performing flood drainage and disaster relief operations, the compartment door is opened to expose the chamber. The mobile cart is then activated and removed along the tilted compartment door, allowing the cart to pull the hose, which in turn drives the drum to begin rotating. Once the mobile cart reaches the location where drainage is required, if the hose is still partially wrapped around the drum, the hose can be pulled off the drum, exposing the end of the hose away from the mobile cart, which is wrapped around the drum. The mobile cart then powers the drainage pump via a battery. Once activated, the pump draws water into the hose through the inlet pipe and then discharges it through the outlet formed by the drum. Thus, during flood drainage operations, the mobile cart is remotely controlled to drive the drainage pump to the drainage location, and the hose is automatically unwound. This demonstrates intelligent disaster relief, eliminating the need for manual labor to remove and place drainage pumps one by one at a time, or to connect electrical circuits and hoses. This makes flood drainage and disaster relief operations more convenient, saves time, and improves efficiency.

[0008] Optionally, a barrier member is provided in the accommodating cavity at the end of the rotating drum away from the water outlet, the barrier member is located on the side of the rotating drum away from the moving trolley, and the barrier member is close to the lower end of the rotating drum and the side opposite to the axial direction.

[0009] By adopting the above technical solution, when the hose is reeled onto the drum, the mobile cart reverses and drains the water in the hose through the drainage pump; then the drum rotates, causing the hose wrapped around the drum to bend under the enclosure of the enclosure and then be wound around the drum, so that the water in the hose can be drained and reeled. While the hose is reeling, the mobile cart also moves into the compartment until the mobile cart returns to the storage chamber, at which point the drum stops rotating, completing the storage of the hose.

[0010] Optionally, the enclosure includes a bottom plate, a first side plate and a second side plate, the bottom plate is located below the rotating drum, the first side plate is located on the side of the rotating drum away from the moving trolley, the second side wall is located on the extension line of the rotating drum axis, and the direction of winding the water hose passes through the bottom plate and the first side plate in sequence.

[0011] By adopting the above technical solution, when the water hose is reeled in, the drum rotates in the direction of the vehicle body backward, so that the water hose passes through the bottom plate and the first side plate in sequence under the rotation of the drum, and under the enclosure of the second side plate, the end of the water hose that exceeds the drum can be bent, and as the drum rotates, under the enclosure of the bottom plate and the first side plate, the water hose is gradually wound around the drum, thereby realizing the reeling of the water hose.

[0012] Optionally, the bottom plate, the first side plate and the second side plate are slidably arranged in the accommodating cavity along the axial direction of the rotating drum, and a gear is coaxially connected to one end of the rotating drum close to the side wall of the vehicle body. A gear is rotated on the side wall of the vehicle body located in the accommodating cavity, and the gear is engaged with the gear. A threaded rod is coaxially connected to the gear, and the threaded rod passes through and is threadedly connected to the second side plate.

[0013] By adopting the above technical solution, when the water hose is wound, the drum rotates in the direction of the vehicle body moving backward, driving the water hose to rotate, and then winding it around the drum under the enclosure of the bottom plate, the first side plate and the second side plate. The rotation of the drum simultaneously drives the gear to rotate through the toothed disc, and then drives the threaded rod to rotate, so that the second side plate approaches the drum under the rotation of the threaded rod. When the drum rotates and winds the water hose, the second side plate drives the bottom plate and the first side plate to move toward the inner wall of the vehicle body, so that when the water hose is wound around the drum, the bottom plate, the first side plate and the second side plate are still moving to straighten the water hose, so that the drum can smoothly wind all the water hose, thereby improving the stability of the water hose winding. When the water hose is unwound, the drum rotates in the direction of the vehicle body to drive the water hose to unwind. At the same time, through the engagement of the toothed disc and the gear, the threaded rod is driven to rotate in the opposite direction, thereby driving the second side plate, the bottom plate and the first side plate to rotate in the direction away from the drum to provide space for unwinding the water hose, which helps to completely unwind the water hose from the drum and avoid tangling.

[0014] Optionally, a guide rod is fixed on the side wall of the vehicle body located in the accommodating cavity, the guide rod slides through the second side plate, and the guide rod is arranged parallel to the threaded rod.

[0015] By adopting the above technical solution, when the threaded rod rotates to drive the second side plate to move, the second side plate is connected to the guide rod through a sliding connection, so that the second side plate is guided by the guide rod when driving the bottom plate and the first side plate to move, thereby improving the stability of the second side plate, the bottom plate and the first side plate when the water hose is wound up.

[0016] Optionally, a rocker located on the end surface of the rotating drum is hinged on the outer wall of the body, and the hinge axis of the rocker is perpendicular to the rotation axis of the rotating drum.

[0017] By adopting the above technical solution, the rocker can be shaken to drive the drum to rotate, thereby realizing the winding and unwinding of the water hose.

[0018] Optionally, a sliding rod is slidably provided on the side wall of the vehicle body located in the accommodating cavity, and the sliding rod slides along the forward direction of the vehicle body, and the end of the sliding rod close to the rotating drum is inserted between the teeth of the gear disk.

[0019] By adopting the above technical solution, when the hose is unwinding or rewinding, the end of the slide rod is inserted between the teeth of the sprocket by sliding the slide rod toward the vehicle's forward direction. When the hose is unwinding or rewinding, the slide rod is slid toward the vehicle's backward direction to remove the end of the slide rod from the teeth of the sprocket.

[0020] Optionally, the vehicle body is rotatably connected to a push rod on the side wall located in the accommodating cavity, and the rotational connection point between the push rod and the vehicle body is located below the slide bar. A limiting column is fixed on the side wall of the vehicle body, and the limiting column is used to abut the push rod and tilt upward toward the outside of the vehicle body. The end of the slide bar away from the gear plate is slidably connected to the push rod. When the compartment door is closed, the upper end of the push rod abuts against the compartment door. After the compartment door is opened, the upper end of the push rod rotates toward the outside of the accommodating cavity, driving the slide bar to disengage from the gear plate.

[0021] By adopting the above technical solution, when the compartment door is opened to release the mobile trolley, the push rod disengages from the compartment door and rotates toward the outside of the compartment body, thereby driving the slide rod to move away from the gear disc and disengage from between the teeth of the gear disc, so as to release the rotation lock of the rotating drum, so that the water hose can be automatically unwound as the mobile trolley moves; when the rotating drum rotates to complete the winding of the water hose, the mobile trolley is located in the accommodating cavity, and the compartment door is closed at this time, so that the compartment door pushes the push rod to rotate into the accommodating cavity, thereby driving the slide rod to slide toward the gear disc, and the end of the slide rod is inserted between the teeth of the gear disc to limit the rotation of the rotating drum, thereby improving the stability of the water hose after storage, and facilitating the automatic unwinding and use of the water hose again.

[0022] Optionally, a pressure spring is fixed on the top wall of the vehicle body located in the accommodating cavity, and one end of the pressure spring away from the top wall of the vehicle body is connected to the upper end of the push rod. The elastic force of the pressure spring acts on the push rod to drive the push rod to rotate toward the outside of the vehicle body.

[0023] By adopting the above technical solution, when the compartment door is opened, the push rod rotates out of the accommodating chamber under the elastic force of the pressure spring, so that the push rod is kept outside the accommodating chamber under the elastic force of the pressure spring, and then the sliding rod is kept away from the gear disc, so that the drum can rotate to smoothly unwind the water hose.

[0024] Optionally, a sliding sleeve is hinged on one end of the sliding rod away from the toothed disc, and the sliding sleeve is slidably mounted on the push rod. The sliding sleeve is provided with a spring buckle that presses tightly against the push rod.

[0025] By adopting the above technical solution, when the water hose is unwound for drainage, the push rod is rotated toward the accommodating chamber, and the spring buckle on the sliding sleeve is pressed at the same time, so that the push rod drives the slide rod to slide toward the gear disc through the sliding sleeve, so that the end of the slide rod is inserted between the teeth of the gear disc, limiting the rotation of the gear disc, and at the same time, the spring buckle of the sliding sleeve is released to lock the sliding of the sliding sleeve and the push rod, thereby limiting the rotation of the push rod and the sliding of the slide rod, so as to lock the state of the slide rod inserted between the teeth of the gear disc, so as to reduce the rotation of the drum when the water hose is draining, thereby improving the stability of the water hose drainage.

[0026] In summary, this application includes at least one of the following beneficial technical effects: During drainage, the drainage pump is driven to the drainage site by a remote-controlled mobile trolley, and the water hose is automatically unwound, reflecting the intelligence of emergency rescue. There is no need for manpower to take out the drainage pumps one by one and place them to the drainage site, nor is there any need for manpower to connect the circuit and water hose, making drainage and disaster relief more convenient, saving time and improving the efficiency of emergency rescue. As the drum rotates, the hose passes through the bottom plate and the first side plate in sequence. The end of the hose that exceeds the drum can be bent under the protection of the second side plate. As the drum rotates, the hose is gradually wound around the drum under the protection of the bottom plate and the first side plate, thus realizing the reeling of the hose. By setting a push rod, a sliding rod and a sliding sleeve, the compartment door push rod is rotated into the accommodating cavity, and then drives the sliding rod to slide toward the gear disc. The end of the sliding rod is inserted between the teeth of the gear disc to limit the rotation of the drum, improve the stability of the water hose after storage, and facilitate the automatic unwinding and use of the water hose again.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses a new energy, large flow, emergency rescue and disaster relief intelligent drainage vehicle. Figure 1 , Figure 1 This is a schematic diagram of the overall structure of a drainage vehicle provided in an embodiment of the present invention, and the drainage vehicle includes a vehicle body 1, a compartment door 2, and a mobile cart 3. The vehicle body 1 has a accommodating chamber 11 for storing a water belt 131 and a drainage pump 32, and a new energy battery 12 at the bottom to supply electricity to the entire vehicle. A rotating drum 13 located on both sides of the vehicle body 1 rotates in the accommodating chamber 11. The compartment door 2 is rotatably arranged at the rear of the vehicle body 1 to seal the accommodating chamber 11. The mobile cart 3 is placed in the accommodating chamber 11 and can be remotely controlled. The mobile cart 3 has a battery 31 and a drainage pump 32 inside. The drainage pump 32 is electrically connected to the battery 31, and the mobile cart 3 has a water inlet pipe 33 connected to the water inlet end of the drainage pump 32. A water hose 131 is provided on the rotating drum 13. The end of the water hose 131 away from the rotating drum 13 is connected to the water outlet end of the drainage pump 32. The end of the rotating drum 13 that is rotatably connected to the vehicle body 1 passes through the side wall of the vehicle body 1 to form a water outlet 132. The rotating drum 13 is used to discharge the water in the water hose 131 out of the vehicle body 1.

[0033] In this embodiment, the vehicle body 1 can be a new energy trailer, powered by a new energy battery 12 at the bottom. A retractable light 14 is also installed on the top of the vehicle body 1 for emergency lighting. The vehicle body 1 also has storage cavities 15 on both sides. These cavities accommodate external water hoses for use when the hose 131 is insufficient. These cavities can also be connected to the water outlet 132 of the drum 13 to discharge drainage water to a distant location via the extended hose 131. The vehicle body 1 also has hinged side doors 151 for closing the storage wall.

[0034] In some other embodiments, the stowage and opening of the compartment door 2 can be driven by a motor to achieve automatic opening and automatic closing.

[0035] In this embodiment, it can be understood that one end of the water hose 131 is connected to the water outlet of the drainage pump 32, and the other end is directly sleeved on the drum 13. When the water hose 131 is not used for drainage, the end of the water hose 131 that exceeds the drum 13 is bent and wound around the drum 13 to achieve the reeling of the water hose 131.

[0036] Furthermore, there is an interface at the bottom of the accommodating chamber 11 for electrically connecting the mobile cart 3 to the new energy battery 12, so that after the mobile cart 3 is received in the accommodating chamber 11, its own battery 31 can be charged in the vehicle body 1 through the interface, so that the mobile cart 3 can be transferred to the next drainage point, which helps to increase the endurance of the mobile cart 3 and the endurance of the drainage pump 32.

[0037] It should be noted that, in this embodiment, there are three drainage pumps 32 on the mobile trolley 3. The three drainage pumps 32 are arranged side by side on the mobile trolley 3, so that the water inlet pipe 33 of the water inlet end of the drainage pump 32 can be placed below the liquid surface to pump water and drain.

[0038] In some embodiments, see Figure 1 and Figure 2 , Figure 2 This is a schematic diagram of the internal cross-section of the drum 13 provided in an embodiment of the present disclosure. A retaining member 16 is provided within the accommodating chamber 11, located at the end of the drum 13 away from the water outlet 132. The retaining member 16 is located on the side of the drum 13 away from the moving trolley 3, and is close to the lower end of the drum 13 and the side directly opposite the axial direction. The retaining member 16 includes a bottom plate 161, a first side plate 162, and a second side plate 163. The bottom plate 161 is located below the drum 13, the first side plate 162 is located on the side of the drum 13 away from the moving trolley 3, and the second side wall is located on the extension line of the axis of the drum 13. The direction of winding the water hose 131 passes through the bottom plate 161 and the first side plate 162 in sequence.

[0039] In this embodiment, the bottom plate 161, the first side plate 162 and the second side plate 163 surround the end of the rotating drum 13 away from the side wall of the vehicle body 1, so as to surround the bottom, end face and side face of the rotating drum 13, so that after the rotating drum 13 rotates in the direction of retreating of the vehicle body 1, the water hose 131 bends under the enclosure of the second side plate 163, bends to the bottom of the rotating drum 13 under the enclosure of the bottom plate 161, and is wound around the rotating drum 13 under the enclosure of the first side plate 162.

[0040] In some embodiments, the bottom plate 161, the first side plate 162, and the second side plate 163 are slidably disposed within the accommodating chamber 11 along the axial direction of the rotating drum 13. A gear wheel 133 is coaxially connected to one end of the rotating drum 13, adjacent to the side wall of the vehicle body 1. A gear 17 is rotatably mounted on the side wall of the vehicle body 1 within the accommodating chamber 11. The gear 17 meshes with the gear wheel 133. A threaded rod 171 is coaxially connected to the gear 17, which passes through and is threadedly connected to the second side plate 163.

[0041] In this embodiment, the toothed disc 133 is coaxial with the rotating drum 13 and rotates against the inner wall of the vehicle body 1. The rotating gear 17 also rotates on the inner wall of the vehicle body 1, with the rotation axis of the gear 17 being parallel to the rotation axis of the toothed disc 133. The rotation axis of the threaded rod 171 is aligned with the rotation axis of the rotating drum 13, so that the rotation of the threaded rod 171 drives the second side plate 163 to slide along the axial direction of the threaded rod 171, thereby driving the bottom plate 161 and the first side plate 162 to slide along the axial direction of the threaded rod 171.

[0042] Furthermore, a guide rod 172 is fixed to the side wall of the vehicle body 1 located within the accommodating cavity 11. The guide rod 172 slides through the second side plate 163 and is arranged parallel to the threaded rod 171. The guide rod 172 restricts the rotation of the second side plate 163 so that the second side plate 163 can only slide along the axial direction of the threaded rod 171, thereby driving the bottom plate 161 and the first side plate 162 to slide along the axial direction of the threaded rod 171, thereby facilitating the bending and winding of the drained hose 131 onto the rotating drum 13.

[0043] For example, a rocker 18 located on the end face of the drum 13 is hinged on the outer wall of the vehicle body 1, and the hinge axis of the rocker 18 is perpendicular to the rotation axis of the drum 13, so that the drum 13 can be driven to rotate outside the vehicle body 1 through the rocker 18 to achieve the reeling of the water hose 131.

[0044] In some embodiments, see Figure 1 and Figure 3 , Figure 3 An enlarged schematic diagram of the stop rod provided in an embodiment of the present disclosure. A slide rod 19 is slidably provided on the side wall of the vehicle body 1 located within the accommodating cavity 11. The slide rod 19 slides along the forward direction of the vehicle body 1. The end of the slide rod 19 close to the rotating drum 13 is inserted between the teeth of the toothed disc 133.

[0045] In this embodiment, the slide rod 19 is located on both side walls inside the vehicle body 1 and slides along the forward or backward direction of the vehicle body 1 to limit the rotation of the gear plate 133 through the sliding of the slide rod 19, thereby ensuring the stability of the drum 13 in winding the water hose 131.

[0046] In some embodiments, a push rod 191 is rotatably connected to the side wall of the vehicle body 1 located in the accommodating chamber 11. The rotational connection point between the push rod 191 and the vehicle body 1 is located below the slide bar 19. A limiting post 193 is fixed to the side wall of the vehicle body 1. The limiting post 193 is used to abut the push rod 191 and tilt it upward toward the outside of the vehicle body 1. The end of the slide bar 19 away from the gear plate 133 is slidably connected to the push rod 191. When the compartment door 2 is closed, the upper end of the push rod 191 abuts the compartment door 2. After the compartment door 2 is opened, the upper end of the push rod 191 rotates toward the outside of the accommodating chamber 11, driving the slide bar 19 to disengage from the gear plate 133. A pressure spring 192 is fixed to the top wall of the vehicle body 1 located in the accommodating chamber 11. The end of the pressure spring 192 away from the top wall of the vehicle body 1 is connected to the upper end of the push rod 191. The elastic force of the pressure spring 192 acts on the push rod 191, driving the push rod 191 to rotate toward the outside of the vehicle body 1.

[0047] In this embodiment, the lower end of the lever 191 abuts against a limiting post 193, which is located on the side of the lever 191 facing away from the slide bar 19. When the door 2 is opened, the force of the compression spring 192 acts on the lever 191, restoring its deformation. This causes the lever 191 to tilt upward, toward the outside of the vehicle body 1, after abutting the limiting post 193. Simultaneously, the lever 191 drives the slide bar 19 toward the outside of the vehicle body 1 and thereby disengages the sprocket 133. When the door 2 is closed, the door 2 pushes the lever 191 away from the limiting post 193 and compresses the compression spring 192, causing the lever 191 to rotate inward of the vehicle body 1, thereby driving the slide bar 19 toward the sprocket 133 and into the teeth of the sprocket 133.

[0048] In some embodiments, a sliding sleeve 194 is hinged at one end of the sliding rod 19 away from the toothed disc 133 . The sliding sleeve 194 is slidably mounted on the push rod 191 . A spring buckle 195 is provided on the sliding sleeve 194 to press tightly against the push rod 191 .

[0049] In this embodiment, the sliding sleeve 194 allows the push rod 191 to drive the slide bar 19 to slide back and forth in the horizontal direction during rotation. The spring clip 195 does not restrict the sliding of the sliding sleeve 195 when not in use. Only when the rotation of the toothed disc 133 and the rotating drum 13 needs to be locked, the spring clip 195 will clamp the push rod 191, restricting the sliding of the sliding sleeve 195 and the push rod 191, thereby restricting the sliding of the slide bar 19 and locking the slide bar 19 between the teeth of the toothed disc 133.

[0050] The implementation principle of the embodiment of the present application, a new energy, large-flow, intelligent drainage vehicle for emergency rescue and disaster relief, is as follows: when draining floods for emergency rescue and disaster relief, the motor drives the compartment door 2 to open automatically. At this time, the pressure spring 192 acts on the push rod 191, causing the push rod 191 to rotate out of the vehicle body 1 and abut against the limit column 193. However, the rotation of the push rod 191 drives the slide rod 19 to slide through the sliding sleeve 194 and then disengage from the gear disc 133, releasing the rotation lock on the gear disc 133 and the rotating drum 13. Then the remote-controlled mobile cart 3 moves from the vehicle body 1 to the place where drainage is required, and extends the water inlet pipe 33 below the liquid surface. In this process, since the rotation lock of the gear disc 133 is released, the water hose 131 is pulled to unwind from the rotating drum 13 during the movement of the mobile cart 3. When the hose 131 is unwound and drives the drum 13 to rotate in the direction of the vehicle body 1, the engagement between the toothed disc 133 and the gear 17 drives the gear 17 to rotate, thereby driving the threaded rod 171 to rotate, so that the bottom plate 161, the first side plate 162, and the second side plate 163 are moved away from the drum 13 along the axial direction of the drum 13, leaving space for the unwinding of the hose 131. When the hose 131 is completely unwound and drainage is completed, the lever 191 can be rotated toward the vehicle body 1, driving the slide bar 19 to lock the rotation of the toothed disc 133. Then, by pressing the spring buckle 194 of the sliding sleeve 194, the lever 191 and the slide bar 19 are locked to limit the rotation of the drum 13, thereby ensuring stable drainage of the hose 131. After the drainage is completed, the drainage pump 32 on the mobile trolley 3 is reversed to drain the remaining water in the water hose 131; the spring buckle 194 of the sliding sleeve 194 is pressed to release the lock on the push rod 191 and the slide rod 19, so that the push rod 191 is rotated out of the vehicle body 1, driving the slide rod 19 to disengage from the gear disc 133. Then the rocker 18 is rotated to drive the drum 13 to reel in, and at the same time, the toothed disc 133 and the gear 17 are engaged, driving the threaded rod 171 to reverse, and then driving the bottom plate 161, the first side plate 162 and the second side plate 163 to rotate toward the drum 13, so that the water hose 131 is bent and wound onto the drum 13, and at the same time the mobile trolley 3 is moved to the accommodating chamber 11 and reset; until the reeling is completed, the mobile trolley 3 is also reset, and the compartment door 2 is closed at this time, and the compartment door 2 pushes the push rod 191 to rotate toward the vehicle body 1, and the push rod 191 drives the slide bar 19 to be inserted between the teeth of the toothed disc 133, completing the automatic storage of the mobile trolley 3 and the water hose 131.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
