Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, specifically to a new energy all-terrain unmanned water cannon vehicle. Background Technology

[0002] With the development of new energy in mountainous areas, problems such as photovoltaic module cleaning and fire fighting in mountainous forests are becoming increasingly serious. Related technologies utilize drones and string-mounted cleaning systems for cleaning photovoltaic modules and fire fighting. However, drones have limited payload capacity, short range on a full charge and with sufficient water, and are constrained by flight control issues. Water pressure is difficult to adjust, and some rely on gravity flow, resulting in poor performance in fire fighting or module cleaning. Drones are also prone to crashing due to crosswinds (the windy conditions in mountainous areas and the turbulent airflow at fire sites exacerbate this), leading to poor safety. Some firefighting drones require support from large fire trucks, have short operating distances, and limited application scenarios. String-mounted cleaning systems consist of a track with cleaning devices along each row of neatly arranged photovoltaic strings, and a water storage tank at the end of the track. This system is expensive, easily damaged, difficult to maintain, and has high maintenance costs, making it uneconomical. It can only be used in open plains, limiting its application scenarios. Due to the complex terrain of mountainous areas, it cannot be applied to mountainous photovoltaic projects; its function is limited, and it cannot perform fire fighting tasks.

Detailed Implementation

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 1 to 5 As shown, the new energy all-terrain unmanned water cannon vehicle of this invention includes a frame 1, a water tank 2, a water cannon assembly 3 and a center of gravity adjustment assembly 4, wherein the length direction of the frame 1 is the front-to-back direction, the width direction of the frame 1 is the left-to-right direction, and the height direction of the frame 1 is the up-to-down direction.

[0027] The chassis 1 is equipped with a travel assembly 11, which adopts a drive wheel or track-type movement structure.

[0028] Optionally, the chassis 1 houses two sets of lithium batteries and four sets of drive units. The four drive units are symmetrically arranged on the left and right sides of the chassis 1. Each drive unit consists of a drive motor, a motor controller, a reduction gearbox, and two drive wheels. The two drive wheels are mounted on a connecting frame that rotates in the forward-backward direction. The connecting frame rotates around the output shaft of the reduction gearbox and is mounted on the chassis. The two drive wheels are equipped with transmission gears and are connected by a transmission chain. The output shaft of the reduction gearbox extends out of the chassis and is connected to the transmission chain. A rigid box is provided on the connecting frame corresponding to the transmission gears and the transmission chain. The connecting frame allows the two drive wheels in the same set to rotate up and down around the output shaft of the reduction gearbox, ensuring close contact with undulating ground and traction. When the left and right drive wheels are turned in opposite directions, the vehicle turns in place. Compared to tracked drive systems, tracks limit the vertical movement of the road wheels. This device allows the drive wheels to move up and down a greater distance than a tracked chassis, resulting in superior traction on dry or hard surfaces.

[0029] The water tank 2 is located above the frame 1, and a partition 21 is provided inside the water tank 2. The partition 21 divides the water tank 2 into a first chamber 22 and a second chamber 23 in the front-to-back direction. The water cannon assembly 3 includes a telescopic rod 31, a nozzle 32, and an infusion pipe 33. The telescopic rod 31 is rotatably mounted on the frame 1, and the nozzle 32 is rotatably mounted on the movable end of the telescopic rod 31. The rotation axis of the nozzle 32 is perpendicular to the extension direction of the telescopic rod 31, that is, the nozzle 32 rotates in a vertical plane. The infusion pipe 33 is located on the telescopic rod 31 and its two ends are respectively connected to the nozzle 32 and the water tank 2. The center of gravity adjustment assembly 4 includes an adjustment pipe 41. The two ends of the adjustment pipe 41 are respectively connected to the first chamber 22 and the second chamber 23. The adjustment pipe 41 is used to adjust the liquid volume in the first chamber 22 and the second chamber 23 to adjust the center of gravity of the water tank 2.

[0030] In use, the new energy all-terrain unmanned water cannon vehicle of this embodiment moves the water cannon vehicle to the working position through the driving component 11, rotates the telescopic rod 31 to adjust the tilt angle and working posture of the telescopic rod 31, rotates the nozzle 32 relative to the telescopic rod 31 to further adjust the water spray angle, and delivers water to the nozzle 32 through the infusion pipe 33 for water spraying operations, thereby cleaning photovoltaic modules or performing fire extinguishing operations. When the vehicle frame 1 is located on an inclined plane, the liquid in the first chamber 22 is delivered to the second chamber 23 or the water in the second chamber 23 is delivered to the first chamber 22 through the regulating pipe 41 to adjust the center of gravity of the water tank 2, thereby adjusting the overall center of gravity of the water cannon vehicle and improving the stability of the water cannon vehicle during driving and operation.

[0031] The new energy all-terrain unmanned water cannon vehicle of this invention has good passability through the frame 1 and the driving component 11, which facilitates the movement of the water cannon vehicle. The height position of the nozzle 32 can be adjusted by setting the telescopic rod 31, and the water cannon component 3 can be stored during the movement, which is convenient for adjustment. By rotating the telescopic rod 31 relative to the frame 1 and the nozzle 32 relative to the telescopic rod 31, the working angle of the nozzle 32 can be adjusted, thereby improving the water spraying effect, so as to facilitate the cleaning of photovoltaic modules or fire fighting operations. The liquid volume in the first chamber 22 and the second chamber 23 can be adjusted by adjusting the adjustment rod, which facilitates the adjustment of the center of gravity of the water storage tank 2 and the fire truck on the slope, thereby improving the overall stability of the fire truck.

[0032] Optionally, the water storage tank 2 is provided with a first liquid inlet communicating with the first chamber 22 and a second liquid inlet communicating with the second chamber 23.

[0033] In some embodiments, such as Figure 1 and Figure 4 As shown, the water cannon assembly 3 includes a first pump 34, a first branch pipe 35, and a second branch pipe 36. The first pump 34 is located on the infusion pipe 33. The first branch pipe 35 and the second branch pipe 36 are connected in parallel on the infusion pipe 33. The other end of the first branch pipe 35 is connected to the first cavity 22, and a first valve 351 is provided on the first branch pipe 35. The other end of the second branch pipe 36 is connected to the second cavity 23, and a second valve 361 is provided on the second branch pipe 36.

[0034] In this embodiment, by setting a first valve 351 on the first branch pipe 35 and a second valve 361 on the second branch pipe 36, it is convenient to deliver water to the infusion pipe 33 through the first branch pipe 35 or the second branch pipe 36. This is safe and reliable, and avoids the first cavity 22 and the second cavity 23 from being connected through the first pipe and the second pipe. This helps to maintain the volume difference of the water in the first cavity 22 and the second cavity 23, thereby helping to maintain the center of gravity of the water cannon vehicle after adjustment and improving the overall stability.

[0035] In some embodiments, the first valve 351 is a one-way valve, and / or the second valve 361 is a one-way valve. Preferably, both the first valve 351 and the second valve 361 are one-way valves. During water spraying operations, the water in the first branch pipe 35 can enter the infusion pipe 33, and the water in the second branch pipe 36 can also enter the infusion pipe 33, which improves the reliability of water supply to the infusion pipe 33. At the same time, the one-way valve can prevent the water in the first branch pipe 35 from flowing back into the first chamber 22 and the water in the second branch pipe 36 from flowing back into the second chamber 23. This makes it easier to maintain the volume difference of the water in the first chamber 22 and the second chamber 23 when water is supplied to the first chamber 22 and the second chamber 23 at the same time, which helps to maintain the center of gravity of the water cannon vehicle after adjustment and improves the overall stability.

[0036] In other embodiments, the first valve 351 may also be a solenoid valve or a manual valve to control the connection between the first branch pipe 35 and the infusion pipe 33, and the second valve 361 may also be a solenoid valve or a manual valve to control the connection between the second branch pipe 36 and the infusion pipe 33.

[0037] In some embodiments, such as Figure 1 and Figure 2 As shown, the water cannon assembly 3 includes a support base 37, which is rotatably mounted on the frame 1 about an axis extending in the vertical direction. The telescopic rod 31 is rotatably mounted on the support base 37, and the axis of rotation of the telescopic rod 31 is perpendicular to the axis of the support base 37. The connection between the support base 37 and the telescopic rod 31 is located above the water storage tank 2. By setting the support base 37, it is convenient to adjust the position of the telescopic rod 31, making operation convenient and thus improving the water spraying effect of the nozzle 32.

[0038] Specifically, the support base 37 is provided with a first gear, the frame 1 is provided with an adjustment motor, the output end of the adjustment motor is provided with a second gear, the second gear meshes with the first gear for transmission, the adjustment motor drives the second motor to rotate, thereby driving the first gear and the support base 37 to rotate relative to the frame 1, so as to adjust the position of the telescopic rod 31.

[0039] Optionally, a hydraulic push rod is provided between the support base 37 and the telescopic rod 31. The hydraulic push rod controls the tilt angle of the telescopic rod 31 relative to the frame 1 through telescopic operation.

[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, the water cannon assembly 3 includes a direct drive assembly 311, and the telescopic rod 31 includes a first rod and a second rod that are plugged into each other. One end of the first rod is rotatably connected to the support base 37, and the nozzle 32 is located at the end of the second rod. The direct drive assembly 311 is fixedly mounted on the first rod, and the movable end of the direct drive assembly 311 is fixedly connected to the second rod. The length of the telescopic rod 31 is adjusted by the plugging and connecting of the first rod and the second rod. The extension and retraction of the direct drive assembly 311 drives the second rod to move relative to the first rod. The operation is convenient and the stability is high.

[0041] Optionally, the direct drive assembly 311 can be an electric actuator, a pneumatic actuator, or a hydraulic actuator.

[0042] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the water cannon assembly 3 includes a drive motor 38 and a reducer 39 that are fixed and connected in transmission. The reducer 39 is fixedly mounted on the movable end of the telescopic rod 31. The output shaft of the reducer 39 is perpendicular to the extension direction of the telescopic rod 31. The output shaft of the reducer 39 is fixedly mounted on a fixing frame 5. A nozzle 32 is fixedly mounted on the fixing frame 5. The axial direction of the nozzle 32 is perpendicular to the output shaft of the reducer 39.

[0043] In this embodiment, the nozzle 32 is fixed by the fixing frame 5, and the fixing frame 5 and the nozzle 32 are driven to rotate by the drive motor 38 and the reducer 39, so as to adjust the spray direction of the nozzle 32. The operation is convenient and reliable, and the water spraying cleaning or fire extinguishing effect is improved.

[0044] Optionally, such as Figure 3 As shown, a camera 51 and a lighting lamp 52 are fixedly installed on the fixed frame 5 to facilitate observation of the specific situation of the water spray point, so as to facilitate grasp of the fire situation and improve the efficiency of fire fighting.

[0045] In some embodiments, such as Figure 4 As shown, the two ends of the regulating pipe 41 are connected to the first branch pipe 35 and the second branch pipe 36 respectively, which reduces the length required for the regulating pipe 41, thereby simplifying the structure and reducing the interference of the pipeline installation on the operation of other components.

[0046] In some embodiments, such as Figure 4 As shown, the center of gravity adjustment assembly 4 also includes a second pump 42 disposed on the adjustment pipe 41. The second pump 42 is a bidirectional booster pump. The input end of the second pump 42 is provided with a third valve 43, and / or the output end of the second pump 42 is provided with a fourth valve 44.

[0047] In this embodiment, the second pump 42, configured as a bidirectional booster pump, can deliver water from the first chamber 22 to the second chamber 23 via the regulating pipe 41 and from the second chamber 23 to the first chamber 22 via the regulating pipe 41, according to operational requirements. This reduces the number of pumps and simplifies the structure. By setting the third valve 43 and / or the fourth valve 44, after the regulating pipe 41 and the second pump 42 regulate the liquid in the first chamber 22 and the second chamber 23, the first chamber 22 and the second chamber 23 are prevented from being connected through the regulating pipe 41, thereby separating the liquid in the first chamber 22 and the second chamber 23. This helps maintain the center of gravity of the water storage tank 2 after adjustment and improves the overall stability.

[0048] In some embodiments, the system further includes a controller and an angle sensor disposed on the frame 1. The controller is electrically connected to the angle sensor and the second pump 42, respectively. The angle sensor is used to measure the tilt angle of the frame 1 in the front-rear direction and transmit the measurement to the controller. The controller is used to control the second pump 42 to deliver the liquid in the first chamber 22 to the second chamber 23 when the frame 1 tilts forward, and the controller is used to control the second pump 42 to deliver the liquid in the second chamber 23 to the first chamber 22 when the frame 1 tilts backward.

[0049] In this embodiment, the water in the first cavity 22 and the second cavity 23 is automatically adjusted by a controller and an angle sensor. The operation is convenient and safe.

[0050] Specifically, the angle sensor is used to monitor the tilt angle of the frame 1. When the frame 1 tilts forward, the angle sensor reading is positive, and when the frame 1 tilts backward, the angle sensor reading is negative. The angle sensor transmits the measured value to the controller. When the value is positive, the controller controls the second pump 42 to transport the liquid in the first chamber 22 to the second chamber 23. When the value is negative, the controller controls the second pump 42 to transport the liquid in the second chamber 23 to the first chamber 22.

[0051] In some embodiments, such as Figure 4 and Figure 6 As shown, the center of gravity adjustment component 4 also includes a water supply pipe 45, which is connected between the first branch pipe 35 and the second branch pipe 36. A three-way valve 46 is provided on the water supply pipe 45, and a water supply connector for connecting the pipe is connected to the three-way valve 46. The three-way valve 46 is used to control the connection of any two of the first branch pipe 35, the second branch pipe 36 and the water supply connector. A fifth valve 47 is provided on the first branch pipe 35 and / or the second branch pipe 36 corresponding to the water supply pipe 45.

[0052] In this embodiment, by setting up a water supply pipe 45 and a three-way valve 46, water can be supplied to the first chamber 22 by connecting the first branch pipe 35 and the water supply connector through the three-way valve 46. Water can also be supplied to the second chamber 23 by connecting the second branch pipe 36 and the water supply connector through the three-way valve 46. Furthermore, the first branch pipe 35 and the second branch pipe 36 can be connected through the three-way valve 46 to connect the first chamber 22 and the second chamber 23, so that the water in the first chamber 22 and the second chamber 23 are the same on a horizontal road. Finally, the fifth valve 47 can be used to block the connection between the first branch pipe 35 and the second branch pipe 36 through the water supply pipe 45 and the infusion pipe 33.

[0053] like Figure 6 As shown, the fifth valve 47 can be installed on the first branch pipe 35 and / or the second branch pipe 36. The fifth valve 47 is a solenoid valve or a manual valve. Optionally, the first valve 351 is a manual valve, the second valve 361 is a manual valve, the two ends of the water supply pipe 45 are respectively connected upstream of the first valve 351 and the second valve 361, the two ends of the regulating pipe 41 are located upstream of the two ends of the water supply pipe 45, the regulating pipe 41 is provided with a third valve 43, the third valve 43 is a solenoid valve, the three-way valve 46 is a manual valve, the fifth valve 47 is installed on the first branch pipe 35, and the fifth valve 47 is located between the connection position of the regulating pipe 41 and the first branch pipe 35 and the connection position of the water supply pipe 45 and the first branch pipe 35.

[0054] During water replenishment operations, the water replenishment connector is connected to the first branch pipe 35 or the second branch pipe 36 via the three-way valve 46. During non-water replenishment operations, the first branch pipe 35 and the second branch pipe 36 are connected via the three-way valve 46. When the water tanker is spraying water, the first valve 351 and the second valve 361 are normally open to supply water to the nozzle 32. The first branch pipe 35 is equipped with a fifth valve 47, which is a solenoid valve. When adjusting the water volume in the first chamber 22 and the second chamber 23, the first branch pipe 35 and the second branch pipe 36 can be blocked from being connected to the infusion pipe 33 via the water replenishment pipe 45 by closing the fifth valve 47, which facilitates the adjustment of the water volume in the first chamber 22 and the second chamber 23.

[0055] In some embodiments, such as Figure 4 As shown, a sixth valve 48 is provided on the water supply pipe. The sixth valve 48 is located at the first output end and / or the second output end of the three-way valve 46. The sixth valve 48 can be a solenoid valve or a manual valve. When not in water supply operation, the sixth valve 48 closes the water supply pipe 45.

[0056] In some embodiments, such as Figure 5 As shown, a first baffle 24 extending in the left-right direction is provided in the first cavity 22. There is a set distance between the left side and / or right side of the first baffle 24 and the side wall of the first cavity 22. The first baffle 24 is provided with at least one in the front-back direction.

[0057] In this embodiment, by setting the first baffle 24, the flow of liquid in the first cavity 22 in the front-to-back direction can be buffered, reducing the impact of the liquid on the water storage tank 2 and the overall center of gravity of the water cannon vehicle during the flow and impact process, and further improving the overall stability of the water cannon vehicle.

[0058] Optionally, the first baffle 24 may have one, two, or three baffles in the front-rear direction.

[0059] In some embodiments, such as Figure 5 As shown, a second baffle 25 extending in the left-right direction is provided in the second cavity 23. There is a set distance between the left side and / or right side of the second baffle 25 and the side wall of the second cavity 23. The second baffle 25 is provided with at least one in the front-back direction.

[0060] In this embodiment, by setting a second baffle 25, the flow of liquid in the second cavity 23 in the front-to-back direction can be buffered, reducing the impact of the liquid on the water storage tank 2 and the overall center of gravity of the water cannon vehicle during the flow and impact process, and further improving the overall stability of the water cannon vehicle.

[0061] Optionally, the second baffle 25 may have one, two, or three baffles in the front-rear direction.
