Description

Technical Field

[0001] This invention relates to the field of high-pressure water pump technology, specifically to a portable high-pressure water pump and its usage method. Background Technology

[0002] As is well known, the most widely used type of high-pressure water pump is the miniature high-pressure water pump. Due to its high pressure, small size, portability, and ability to be powered by a vehicle battery, it is commonly used for cleaning, spraying, misting, pressurization, and water pumping.

[0003] High-pressure water pumps are large and heavy, making them inconvenient to move, which greatly limits their use. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a portable high-pressure water pump and its usage method.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a portable high-pressure water pump, comprising a base, a pump body, a lifting assembly, and a moving assembly. The pump body is disposed on the base, and a lifting groove is disposed below the base. The lifting assemblies are disposed on both the front and rear sides of the base. The pump body is disposed between two sets of lifting assemblies. Each set of lifting assemblies includes two symmetrically arranged first motors, screws, and lifting plates. The first motors are disposed above the base, and the screws are disposed within the lifting grooves. The upper part of the screws passes through the base and is connected to the output end of the corresponding first motor. The lifting plates are disposed within the lifting grooves, and screw holes are provided on the left and right sides of the lifting plates. The screws pass through the screw holes. A moving assembly for moving the base is disposed below the lifting plates.

[0008] The moving component includes a driver, a hinge frame, a turntable, casters, directional wheels, and a support pad. Two sets of symmetrically arranged hinge frames are provided below each set of lifting plates. Each set of hinge frames has a hinge slot below it. The turntable is hinged to the side wall of the corresponding hinge slot. The driver is located on the side wall of one set of hinge frames. A transmission rod is provided between the two sets of hinge frames. Both ends of the transmission rod pass through the corresponding hinge frame and are connected to the corresponding turntable. The output end of the driver passes through the corresponding hinge frame and is connected to the turntable. The turntable is equipped with the casters, directional wheels, and support pad.

[0009] To ensure stable operation of the equipment, the present invention is improved in that the universal wheels, directional wheels and support pads are arranged in a circular array on the turntable.

[0010] Furthermore, to facilitate the fixing of the equipment, the present invention is improved by providing a brake assembly for braking the universal wheel on its circumference.

[0011] To reduce the need for a flat surface on the ground, the present invention is improved by providing several hollow grooves that communicate with the lifting groove below the base.

[0012] To facilitate protection of the first motor, the present invention is improved by providing a protective cover on the base for protecting the first motor, and the first motor is disposed inside the protective cover.

[0013] To facilitate pushing the device, the present invention is improved by providing handrails for pushing the base on both the front and rear sides above the base.

[0014] The present invention further provides a method for using a portable high-pressure water pump, comprising the following steps:

[0015] Step 1: In the initial state, the bottom of the moving component is in the lifting slot, and the whole equipment is in a fixed state. The external controller with a display screen is used to understand the status of the two sets of lifting components.

[0016] Step 2: When the equipment needs to be moved, depending on the requirements, the casters or directional wheels of the moving component are at the bottom. At the same time, the two sets of lifting components are started. The two first motors of each lifting component start simultaneously, driving the screw to rotate. The lifting plate moves downward, so that the bottom of the moving component contacts the ground.

[0017] Step 3: Control the movement of the equipment using the handrail;

[0018] Step 4: When the equipment moves to the designated position, the lifting component drives the moving component to be stored in the lifting slot.

[0019] Preferably, in step 1, the lifting assembly has three states: the omnidirectional wheel is at the bottom, the directional wheel is at the bottom, and the support pad is at the bottom. The driver includes a second motor, a reducer, and a locking device. The output end of the second motor is connected to the input end of the reducer, and the output end of the reducer is connected to the corresponding turntable. The reducer is equipped with a locking device for locking the reducer. A counter is installed on the motor to measure the motor speed, and it is connected to an external controller to measure the status of the moving assembly.

[0020] Preferably, in step 2, both sets of lifting plates are equipped with position sensors for determining the position of the lifting plate and the top wall of the lifting channel. Depending on the requirements, the two sets of lifting plates can be in a state of one high and one low, so that the equipment is in a state of forward tilt or backward tilt, which facilitates the movement of the equipment.

[0021] Preferably, in step 4, if the ground is not flat enough when fixing, the stored movable component becomes the state where the support pad is at the bottom, and the lifting component controls the corresponding movable component to descend, ensuring its support stability.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, the present invention provides a portable high-pressure water pump and its method of use, which has the following beneficial effects:

[0024] This portable high-pressure water pump and its usage method are highly integrated. The state of the moving components can be adjusted according to the user's needs. The height of the moving components can be adjusted through the corresponding lifting components to further meet the user's needs for moving the equipment.

[0025] The portable high-pressure water pump and its usage method: when the movable component is stored in the lifting slot, the base is in contact with and fixed to the ground. When the flatness of the ground does not meet the equipment requirements, the brake component fixes the casters at the bottom or the support pad at the lowest point, and works with the lifting component to support the base, thus achieving stable fixation of the base.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-5 A portable high-pressure water pump includes a base 1, a pump body 2, a lifting assembly, and a moving assembly. The pump body 2 is mounted on the base 1, and a lifting groove is provided below the base 1. The lifting assemblies are provided on both the front and rear sides of the base 1. The pump body 2 is positioned between two sets of lifting assemblies. Each set of lifting assemblies includes two symmetrically arranged first motors 3, screws 4, and lifting plates 5. The first motors 3 are positioned above the base 1, and the screws 4 are positioned within the lifting grooves. The upper part of the screws 4 passes through the base 1 and connects with the corresponding first motor 3. The output end of motor 3 is connected, and the lifting plate 5 is provided in the lifting groove. The lifting plate 5 has screw holes on the left and right sides, and the screw 4 passes through the screw holes. A moving component for moving the base 1 is provided below the lifting plate 5. The pump body 2 is a common high-pressure water pump on the market, whether vertical or horizontal. The two sets of first motors 3 of the corresponding lifting component move synchronously. The first motor 3 drives the screw 4 to rotate, and the lifting plate 5 descends in the lifting groove. The lowest end of the moving component contacts the ground and supports the base 1. The moving component facilitates the movement of the equipment.

[0034] Depending on the specific needs, a single moving component cannot meet all requirements. Therefore, in this embodiment, the moving component includes a driver 6, a hinge frame 7, a turntable 8, casters 9, directional wheels 10, and a support pad 11. Two symmetrically arranged hinge frames 7 are provided below each set of lifting plates 5. Each set of hinge frames 7 has a hinge groove below it. The turntable 8 is hinged to the sidewall of the corresponding hinge groove. The driver 6 is located on the sidewall of one set of hinge frames 7. A transmission rod is provided between the two sets of hinge frames 7, with both ends of the transmission rod passing through the corresponding hinge. The connecting frame 7 is connected to the corresponding turntable 8. The output end of the driver 6 passes through the corresponding connecting frame 7 and is connected to the turntable 8. The turntable 8 is provided with the universal wheels 9, the directional wheels 10 and the support pad 11. The output end of the driver 6 drives the turntable 8 of one set of connecting frames 7 to rotate. The transmission rod is fixedly connected to the two sets of turntables 8. The other set of turntables 8 below the corresponding lifting plate 5 also rotates. When the four sets of universal wheels 9 are downward, it is convenient for the equipment to move in multiple directions. When the directional wheels 10 are downward, it is convenient for the equipment to move only back and forth. When the support pad 11 is downward, the equipment is fixed and cannot move.

[0035] In the above structure, the spacing between the caster wheel 9, the directional wheel 10 and the support pad 11 can be arranged arbitrarily. In order to facilitate coordination and management, in this embodiment, the caster wheel 9, the directional wheel 10 and the support pad 11 are arranged in a circular array on the turntable 8.

[0036] In actual use, it is sometimes necessary to temporarily fix the equipment. In order to meet the above requirements, in this embodiment, a brake assembly 12 for braking the universal wheel 9 is provided on the periphery of the universal wheel 9.

[0037] In actual use, it was found that the ground is not always completely flat, and the base 1 may be unstable. In order to solve the above problems, in this embodiment, a number of hollow grooves that communicate with the lifting groove are provided under the base 1.

[0038] During actual use of the equipment, water stains will inevitably fall on the first motor 3, which may damage the first motor 3. In order to solve the above problem, in this embodiment, a protective cover 14 for protecting the first motor 3 is provided on the base 1, and the first motor 3 is disposed inside the protective cover 14.

[0039] To facilitate pushing the device, handles 13 for pushing the base 1 are provided on both the front and rear sides above the base 1.

[0040] The present invention further provides a method for using a portable high-pressure water pump, comprising the following steps:

[0041] Step 1: In the initial state, the bottom of the moving component is in the lifting slot, and the entire device is in a fixed state. The device is connected to an external controller with a display screen to understand the status of the two sets of lifting components. The lifting components include three states: the universal wheel 9 is at the bottom, the directional wheel 10 is at the bottom, and the support pad 11 is at the bottom. The driver 6 includes a second motor, a reducer, and a locking device. The output end of the second motor is connected to the input end of the reducer, and the output end of the reducer is connected to the corresponding turntable 8. The reducer is equipped with a locking device for locking the reducer. A counter is installed on the motor to understand the motor speed. It is connected to the external controller to understand the status of the moving component. How the controller with the display screen is connected to the moving component is a well-known technical means for those skilled in the art.

[0042] Step 2: When the equipment needs to be moved, the universal wheels 9 or directional wheels 10 of the moving component are positioned at the bottom, and the two sets of lifting components are activated simultaneously. The two first motors 3 of each lifting component are activated simultaneously to drive the screw 4 to rotate, and the lifting plate 5 moves downward so that the bottom of the moving component contacts the ground. Both sets of lifting plates 5 are equipped with position sensors to determine the position of the lifting plate 5 relative to the top wall of the lifting groove. As needed, the two sets of lifting plates 5 can be in a state of being one high and one low, so that the equipment is in a state of being tilted forward or backward, which facilitates the movement of the equipment. The lifting components and position sensors are all connected to a controller with a display screen. This connection method is a technical means well known to those skilled in the art.

[0043] Step 3: Control the movement of the equipment via the handrail 13;

[0044] Step 4: When the equipment is moved to the designated position, the lifting component drives the moving component to be stored in the lifting slot. If the ground is not flat enough when it is fixed, the stored moving component will become the support pad 11 at the bottom. The lifting component controls the corresponding moving component to descend to ensure its support stability.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
