[0060] Please refer to Figures 1 to 9 The embodiment provides a cover structure facilitating opening of a mobile pump station, comprising:
[0061] a base plate 1;
[0062] a water pump 2 arranged on the base plate 1;
[0063] a cover body 4 hingedly connected with the base plate 1 and capable of being flipped up and down about a hinge position 41 between the cover body 4 and the base plate 1; and
[0064] a flipping mechanism 3 connected with the cover body 4 and the base plate 1 and used for flipping the cover body 4 up and down about the hinge position.
[0065] In a preferred embodiment, the flipping mechanism 3 comprises a telescopic rod 31 and a power system, one end of the telescopic rod 31 is hingedly connected with the base plate 1, the other end of the telescopic rod 31 is hingedly connected with the cover body 4, and the power system is used for driving telescopic action of the telescopic rod 31 to flip the cover body 4 up and down about the hinge position 41.
[0066] It should be noted that the connection mode of the telescopic rod 31 and the cover body 4 can be diversified, allowing direct connection or indirect connection mode, i.e. through the introduction of transmission components such as link assemblies, to build a linkage bridge between the two, so as to flexibly adjust the direction and size of the force to meet the mechanical requirements of the cover body 4 flipping under different working conditions. Similarly, at the connection end of the telescopic rod 31 and the base plate 1, both direct and indirect connection modes are provided, so as to accurately optimize the overall structure design according to the specific layout of the pump station, the bearing requirements, and the operation convenience and other factors, to ensure stable operation of the system.
[0067] When maintenance or repair of the mobile pump station is required, the operator can start the power system to extend or retract the telescopic rod 31. For example, when the telescopic rod 31 is extended, it will push the cover 4 to flip up, thereby opening the cover 4 to facilitate access to the components on the chassis 1. Conversely, when the telescopic rod 31 is retracted, it will pull the cover 4 to flip down and cover the chassis 1. This design reduces the need for additional lifting equipment, simplifies the opening process of the cover 4, making the opening and closing of the cover 4 quick and easy, and improves the efficiency of the repair.
[0068] Referring to Figures 1 to 3 In this embodiment, the telescopic rod 31 is a lifting cylinder 311, and the power system is a hydraulic power system configured to provide hydraulic power to the lifting cylinder 311 through manual and / or electric control. For manual control, the operator can manually drive the hydraulic power system to provide hydraulic power, such as a hand pump 33 or the like. This method relies on manual operation of a specific mechanical structure to generate the necessary pressure to control the action of the lifting cylinder 311, which is particularly suitable for situations where there is no external power supply. For electric control, the operator can use a remote control 38 or a button to remotely operate the electronic control means, and the controller 37 sends a signal to activate the hydraulic system to complete the flipping action of the cover 4, providing a more convenient operation experience.
[0069] Preferably, the hydraulic power system has both manual and electric control modes for driving the lifting cylinder 311, greatly enhancing the adaptability of the system, allowing it to cope with different use scenarios and emergency needs, and ensuring stable operation of the system and a good user experience.
[0070] In some embodiments, instead of using a hydraulic power system to drive the lifting cylinder to flip the cover, the telescopic rod 31 can be an electric push rod or a gas cylinder, and the flipping power of the cover can be provided by the electric push rod or the gas cylinder.
[0071] Referring to Figure 1 and Figure 2 In this embodiment, the cover structure further includes a shock-absorbing block 5 arranged on the bottom of the cover 4 for contact with the chassis 1. Preferably, a plurality of shock-absorbing blocks 5 are evenly arranged along the bottom of the cover 4. The shock-absorbing block 5 is usually made of elastic material (such as rubber, polyurethane, etc.) to provide good cushioning and shock-absorbing effect. When the cover 4 is closed, the shock-absorbing block 5 first contacts the chassis 1, providing initial cushioning, absorbing impact force, reducing direct impact on the cover 4 and the chassis 1, and preventing the cover 4 and the chassis 1 from being knocked.
[0072] Referring to Figure 4In this embodiment, the cover structure further comprises an engine 6 provided on the base 1, when the cover 4 is placed on the base 1, the cover 4 covers all or part of the engine 6 and all or part of the water pump 2. The cover 4 provides a physical barrier to prevent the external environment (such as branches, dust, rain, sunlight, etc.) from affecting these key components. The cover 4 does not hinder the normal operation of the object, for example, for the water pump 2, the external water suction pipe is necessary for its normal work. Therefore, the water inlet of the water pump 2 needs to be exposed when designing the cover 4 to ensure that the water suction pipe can be connected smoothly and does not affect the working efficiency of the water pump 2.
[0073] Please refer to Figure 4 In this embodiment, the engine 6 not only provides power for the power oil pump 34 of the hydraulic power system, but also can provide power for the water pump 2, that is, such an engine 6 has two output shafts, one of which is connected with the input shaft of the power oil pump 34, and the other of which is connected with the input shaft of the water pump 2. In addition, after the engine 6 drives the power oil pump 34 to supply oil, the power oil pump 34 provides power for the traveling motor of the base 1 through other valve groups, so that the base 1 moves and other hydraulic execution components of the mobile pump station move.
[0074] Hereinafter, several embodiments of the hydraulic power system are described respectively:
[0075] First embodiment of the hydraulic power system
[0076] Please refer to Figure 5 and Figure 6 In this embodiment, the hydraulic power system comprises a hydraulic oil tank 32 and a hand pump 33, the oil outlet of the hydraulic oil tank 32 is connected with the oil inlet of the hand pump 33, and the two working oil outlets of the hand pump 33 are respectively connected with the rod cavity and the rodless cavity of the lifting cylinder 311, and the hand pump 33 is provided on the base 1. It should be noted that the hand pump 33 has two working oil outlets: one of which is set as an oil outlet for outputting oil; the other is a return oil port responsible for recovering oil, and the operation is driven by controlling the handle of the hand pump 33. The hand pump also has a return oil port connected with the oil tank, so that the hydraulic oil can flow back to the oil tank. Among them, the rod cavity refers to the space on the side of the hydraulic cylinder where the piston rod extends, and the rodless cavity refers to the space on the side of the hydraulic cylinder without the piston rod.
[0077] The operator shakes the handle 331, the hand pump 33 sucks and presses the hydraulic oil, forms a hydraulic flow, and delivers the hydraulic oil after being pressurized to the lifting cylinder 311. If the hydraulic oil enters the rodless cavity, it will push the piston rod to extend. If the hydraulic oil enters the rod cavity, it will pull the piston rod to retract. As an embodiment, the piston rod extends, which will push the cover 4 to turn up, thereby opening the cover 4, and the piston rod retracts, which will push the cover 4 to turn down and cover on the base 1.
[0078] Please refer to Figure 1 and Figure 3 In this embodiment, there are two lifting oil cylinders 311, which are located at the left and right ends of the chassis 1. One working oil port of the hand pump 33 is connected to the corresponding rod cavity of the two lifting oil cylinders 311 through an oil pipe, and the other working oil port of the hand pump 33 is connected to the corresponding rodless cavity of the two lifting oil cylinders 311 through an oil pipe. The two lifting oil cylinders 311 are symmetrically distributed at the left and right ends of the chassis 1, which ensures uniform distribution of force when the cover body 4 is turned over, and avoids the problem of shaking or instability caused by uneven force on one side.
[0079] Please refer to Figures 1 to 5 In this embodiment, the cover body 4 is hinged at the rear end of the chassis 1, and the lifting oil cylinder 311 is located at the rear end of the chassis 1. The rear end of the chassis 1 has a slot 11 in the middle, and the two lifting oil cylinders 311 are located on the left and right sides of the slot 11. The hand pump 33 is arranged at the front right end of the chassis 1, and the oil pipe between the hand pump 33 and the lifting oil cylinder 311 at the left end of the chassis 1 crosses the slot. The outer cover structure further includes a plurality of pipe clamps arranged on the chassis for clamping the oil pipe. Since the components in the hydraulic power system are a distance apart, the mobile pump station may encounter various complex environments and vibration conditions when working. The unsecured oil pipe is prone to friction or collision with other components, causing damage. The use of pipe clamps 36 to securely fix the oil pipe on the chassis 1 reduces this risk and makes the oil pipe layout more orderly.
[0080] Since the water pump 2 is usually installed at the front end of the chassis 1, turning the cover body 4 upward exposes the water pump 2 located in the front, facilitating the maintenance and assembly of the water pump 2. The hinge point of the cover body 4 is located at the rear end of the chassis 1, close to the lifting oil cylinder 311. The design of the cover body 4 opening from back to front can effectively protect other important components at the rear end of the chassis 1, such as the engine 6.
[0081] The upper and lower through slots 11 in the middle of the rear end of the chassis 1 not only provide a wiring channel for the oil pipe, but also provide a good heat dissipation path for the key equipment installed at this position, such as the engine 6 and the hydraulic oil pump. Through natural convection or forced ventilation, heat can be quickly dissipated from the slot 11, keeping the working temperature of the equipment within a safe range and prolonging the service life of the equipment.
[0082] It should be noted that the oil inlet of the hand pump 33 is also connected to the hydraulic oil tank 32 through an oil pipe. Among the several oil pipes, one or more oil pipes can be selected for fixation using pipe clamps 36 according to actual needs, and priority is given to fixing longer oil pipes. For example, in Figure 3 、 Figure 6In the design shown, since the hand pump 33 and the lifting oil cylinder 311 are respectively located at the front and rear ends of the chassis 1, the two relatively long oil pipes between the hand pump 33 and the lifting oil cylinder 311 are firmly clamped and fixed by the pipe clamp 36, which ensures that they will not be displaced or damaged in a high-pressure environment, thereby enhancing the stability and safety of the system, while the hydraulic oil tank 32 is located in the middle of the chassis 1, and the length of the oil pipe between it and the hand pump 33 is relatively short, so it can be fixed without the pipe clamp 36.
[0083] In this embodiment, the oil pipes in the hydraulic power system preferably use seamless steel pipes. This material selection not only improves the pressure resistance and durability of the system, but also facilitates assembly with the pipe clamp 36.
[0084] Please refer to Figure 3 and Figure 5 In this embodiment, the front end of the chassis 1 has a front wall 12, the hand pump 33 is located behind the front wall 12, the front wall 12 has an operating slot 121 corresponding to the position of the hand pump 33, and the handle 331 of the hand pump 33 is located at the front end of the hand pump 33 and opposite the operating slot 121. The front wall 12 serves as a physical barrier to effectively protect the hand pump 33 behind it, and also makes the mobile pump station more aesthetically pleasing. The hand pump 33 is in a relatively concealed but easily accessible position, and the front wall 12 has an operating slot 121 corresponding to the position of the hand pump 33, ensuring that the user can directly operate the handle 331 of the hand pump 33 through the slot.
[0085] Please refer to Figure 8 In this embodiment, the pipe clamp 36 includes a cover plate 361 and a supporting plate 362, the cover plate 361 and the supporting plate 362 are opposite to each other, the cover plate 361 is located above the supporting plate 362, the top of the cover plate 361 has an upper slot 3611, and the top of the supporting plate 362 has a lower slot 3621, the upper slot 3611 and the lower slot 3621 form a clamping space to clamp the oil pipe, the cover plate 361 and the supporting plate 362 are connected by bolts, and the supporting plate 362 is arranged on the chassis 1. The cover plate 361 and the supporting plate 362 are provided with holes matched with the bolts, the bolts make the pipe clamp 36 easy to install and disassemble, facilitating technicians to carry out daily inspection and maintenance, and reducing complex disassembly steps.

[0091] The controller 37 is responsible for receiving operation instructions from the remote controller 38 or other input components (such as an electric control box), and processing according to a preset program or logic. The controller 37 converts the received instructions into electric signals through an internal circuit, and the electric signals are used to drive the electric proportional directional valve 35. The electric proportional directional valve 35 can proportionally change the position of a valve core according to the size of the input current, so that the flow and direction of the hydraulic oil can be continuously adjusted, to ensure smoothness and accuracy of the action of the cover body 4.
[0092] The remote controller 38 is connected with the controller 37 through wireless communication technology, realizing the ability to remotely control the hydraulic power system. The remote controller 38 includes a transmitter and a receiver. The transmitter is the part directly operated by the user, usually in the form of a handle, equipped with buttons, touch screens or other input components, for receiving the user's operation instructions. The receiver is installed on the mobile pump station and can communicate with the controller 37 through a wired connection. It is built-in with a wireless receiving module that can capture radio wave signals from the transmitter and convert them into electrical signals.
[0093] Please refer to Figure 6 In this embodiment, the electric proportional directional valve 35 is a three-position electric proportional directional valve 35 with the middle position being off. In this embodiment, the electric proportional directional valve 35 is equipped with a handle 351, through which the spool of the electric proportional directional valve 35 can be switched to control the oil outlet direction. The electric proportional directional valve 35 is integrated with a mechanical handle 351. By rotating or pushing the handle 351, the user can change the position of the spool to adjust the flow path of the hydraulic oil, realizing the extension or retraction of the lifting cylinder 311. The dual mode of electric control and manual operation provides additional safety for the system. If there is a failure in the electric control, the operator can immediately take action through the manual handle 351 to avoid accidents.
[0094] In this embodiment, one working oil port of the electric proportional directional valve 35 is connected through an oil pipe between the corresponding rod cavities of the two lifting cylinders 311, and the other working oil port of the electric proportional directional valve 35 is connected through an oil pipe between the corresponding rodless cavities of the two lifting cylinders 311. The spool of the electric proportional directional valve 35 is controlled by the electromagnetic valve to switch the corresponding working oil port. One of the two working oil ports of the electric proportional directional valve 35 serves as the oil outlet, and the other working oil port serves as the oil return.
[0095] Please refer to Figures 1 to 4 , Figure 7 In this embodiment, the cover 4 is hinged to the rear end of the chassis 1, the lifting cylinders 311 are located at the rear end of the chassis 1, the rear end of the chassis 1 has a through slot 11 in the middle, there are two lifting cylinders 311 on the left and right ends of the chassis 1 and on the left and right sides of the slot 11, the electric proportional directional valve 35 is located at the right end of the chassis 1, and the oil pipe between the electric proportional directional valve 35 and the lifting cylinder 311 at the left end of the chassis 1 passes through the slot 11. Pipe clamps 36 can be provided on the side wall or edge of the slot 11 to clamp the oil pipe between the electric proportional directional valve 35 and the lifting cylinder 311 at the left end of the chassis 1. The cover structure also includes a plurality of pipe clamps 36 arranged on the chassis 1 to clamp the oil pipe.
[0096] Please refer to Figure 8It is worth mentioning that the pipe clamp 36 structure of the second embodiment can refer to the pipe clamp 36 structure of the first embodiment. In addition, in the second embodiment, one or more oil pipes can be fixed by the pipe clamp 36 according to actual needs, and the oil pipes with longer length are preferred to be fixed. The electric proportional directional valve 35 is close to the lifting oil cylinder 311 on the same side, and the distance between them is short, so the pipe clamp 36 is not needed to be arranged. The electric proportional valve is far away from the lifting oil cylinder 311 on the opposite side, and the distance between them is long, so the pipe clamp 36 is arranged to fix the oil pipes between them.
[0097] Please refer to Figure 4 In the embodiment, the power source is the engine 6 installed on the chassis 1, and the engine 6 is located above the slot 11. The oil pipe between the electric proportional directional valve 35 and the lifting oil cylinder 311 located at the left end of the chassis 1 passes through the slot 11 below the engine 6. The upper and lower through slots 11 in the middle of the rear end of the chassis 1 provide a wiring channel for the oil pipe, and the oil pipe passes through the slot 11 below the engine 6. This wiring method not only reduces the risk of the oil pipe being exposed, but also avoids the interference between the oil pipe and other components, thereby improving the reliability of the system. The slot 11 can provide a good heat dissipation path for the key equipment (such as the engine 6 and the hydraulic oil pump) installed in this position. Through natural convection or forced ventilation, heat can be quickly dissipated from the slot 11, so that the working temperature of the equipment is kept within a safe range, and the service life of the equipment is prolonged.
