Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a mobile photovoltaic power generation device. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. Various municipal projects often do not have good construction conditions at the beginning of the project, and the power supply is unstable, so temporary generators are needed. Mobile photovoltaic power generation devices can flexibly respond to these needs and provide reliable power supply for temporary or mobile applications.

[0003] The Chinese patent "Mobile Photovoltaic Power Generation Device" authorization announcement number "CN215498817U" can be moved to other areas through two track wheels, which is convenient for multiple uses, helps to reduce the number of equipment purchased and save costs. When the device is fixed, a weighted water bag is set at each end of the base to improve the stability of the mobile photovoltaic power generation device.

[0004] It only uses weighted water bags to position the device, but because the tracks themselves are mobile and the road surface at the construction site is usually rough and undulating, there is a risk of the tracks moving when stationary, increasing the instability of the device when it is stationary.

[0005] Therefore, a mobile photovoltaic power generation device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a mobile photovoltaic power generation device in order to solve the above-mentioned problem, which improves the positioning of the device by only using a weighted water bag. However, since the track itself is movable and the road surface at the construction site is usually rough and undulating, there is a risk of the track moving when it is stationary, which increases the instability of the device when it is stationary.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions: a mobile photovoltaic power generation device, comprising: a base, a mounting rod fixedly connected to the top of the base, photovoltaic panels are arranged on both sides of the mounting rod, track wheels are arranged at the bottom of the base, and a positioning mechanism is arranged on the surface of the base; wherein the positioning mechanism comprises a first water tank fixedly connected to the top of the base and a positioning assembly, two mounting plates are installed on the top of the positioning assembly, the surface of the mounting plate is fixedly connected to the surface of the base, mounting plates are fixedly connected to both sides of the base, a second water tank is fixedly connected to the inner wall of the mounting plate, a water inlet pipe is connected between the second water tank and the first water tank, and a first switch solenoid valve is arranged on the surface of the water inlet pipe.

[0008] Preferably, the positioning assembly includes a limit plate slidably connected to the bottom end of the mounting plate, the bottom end of the limit plate is fixedly connected to the positioning plate, the inner wall of the second water tank is slidably connected to the piston plate, the bottom end of the piston plate is fixedly connected to a round rod, the bottom end of the round rod passes through the second water tank and is fixedly connected to the movable plate, one side of the movable plate is hinged with a connecting plate, the surface of the positioning plate is fixedly connected to a fixed plate, and the other end of the connecting plate is hinged to the top of the fixed plate. By setting the positioning mechanism, when the device moves to the desired position, the aqueous solution inside the first water tank flows into the two second water tanks at the same time under the action of gravity, automatically driving the operation of the positioning assembly, and at the same time, the positioning assembly is set, the two movable plates move downward at the same time under the action of the gravity of the aqueous solution, and under the action of the connecting plate, it is conducive to making the two positioning plates close to each other and fixing the track wheel from both sides of the track wheel to achieve the positioning operation of the track wheel, thereby avoiding the track wheel from moving when stationary, which is conducive to improving the stability of the device when stationary.

[0009] Preferably, the inner wall of the positioning plate is fixedly connected with a contact pad, and the surface of the contact pad is provided with grooves distributed in equal rows. The provision of strip grooves of the contact pad is conducive to increasing the friction between the positioning plate and the track wheel, thereby increasing the stability of the positioning plate when positioning the track shoe.

[0010] Preferably, a spring is fixedly connected to the bottom end of the piston plate, and the bottom end of the spring is fixedly connected to the inner bottom wall of the second water tank. When the aqueous solution in the second water tank is discharged, the spring helps to reset the piston plate, thereby releasing the positioning plate from positioning the track wheel.

By arranging the coordinated use of the water pump, the three-way pipe and the connecting pipe, when the device moves, it is beneficial to make the aqueous solution flow back into the first water tank, which is beneficial to increase the weight of the base, thereby enhancing the stability of the device when moving.

[0012] Preferably, the connecting pipe is a bellows. By setting the connecting pipe as a bellows, when the piston plate moves up and down, it is helpful to ensure that the connecting pipe is used normally.

[0013] Preferably, the positioning plate is an arc-shaped plate, and the contact pad is a rubber member, which is conducive to better contact with the surface of the track wheel, and at the same time, the rubber contact pad is conducive to increasing the friction force of contact with the surface of the track wheel.

[0014] Preferably, the two positioning plates are symmetrically distributed on both sides of the track wheel, which is conducive to enabling the two positioning plates to complete the positioning operation of the track wheel at the same time, thereby ensuring the stability during positioning.

[0015] The beneficial effects of the utility model are:

[0016] By setting a positioning mechanism, when the device moves to the desired position, the aqueous solution in the first water tank flows into the two second water tanks at the same time under the action of gravity, automatically driving the operation of the positioning component. At the same time, the positioning component is set, and the two moving plates move downward at the same time under the action of the gravity of the aqueous solution.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a mobile photovoltaic power generation device includes: a base 1, a mounting rod 2 is fixedly connected to the top of the base 1, photovoltaic panels 3 are arranged on both sides of the mounting rod 2, a track wheel 4 is arranged at the bottom of the base 1, and a positioning mechanism 5 is arranged on the surface of the base 1; wherein the positioning mechanism 5 includes a first water tank 501 and a positioning assembly 506 fixedly connected to the top of the base 1, two mounting plates 502 are installed on the top of the positioning assembly 506, the surface of the mounting plate 502 is fixedly connected to the surface of the base 1, the mounting plates 502 are fixedly connected to both sides of the base 1, the inner wall of the mounting plate 502 is fixedly connected to the second water tank 503, the second water tank 503 is connected to the first water tank 501 through a water inlet pipe 504, and the surface of the water inlet pipe 504 is provided with a first switch solenoid valve 505. The top ends of the two photovoltaic panels 3 are hinged to the top end of the mounting rod 2. A sleeve is slidably connected to the surface of the mounting rod 2. Two connecting rods are fixedly connected to the surface of the sleeve. The other ends of the connecting rods are hinged to one side of the corresponding photovoltaic panel 3. The inclination angle of the photovoltaic panel 3 is adjusted by moving the sleeve up and down.

[0026] The track wheel 4 includes a transmission belt and a rotating wheel. Both ends of the rotating wheel are rotatably connected to the inner wall of the base 1 , and the surface of the transmission belt is transmission-connected to the inner wall of the base 1 .

[0027] When the device needs to be moved, the mounting rod 2 is pushed. At this time, under the action of the track wheel 4, the device as a whole moves, and the first water tank 501 is filled with an aqueous solution to increase the weight of the base 1, making the base 1 more stable when moving. When the device moves to the desired position, the two first switch solenoid valves 505 in the positioning mechanism 5 are opened. At this time, the aqueous solution inside the first water tank 501 enters the interior of the two second water tanks 503 at the same time through the two water inlet pipes 504 under the action of gravity, and drives the positioning component 506 to operate.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the positioning assembly 506 includes a limit plate 5061 slidably connected to the bottom end of the mounting plate 502, a positioning plate 5062 is fixedly connected to the bottom end of the limit plate 5061, a piston plate 5063 is slidably connected to the inner wall of the second water tank 503, a round rod 5064 is fixedly connected to the bottom end of the piston plate 5063, the bottom end of the round rod 5064 passes through the second water tank 503 and is fixedly connected to a moving plate 5065, a connecting plate 5067 is hinged to one side of the moving plate 5065, a fixed plate 5066 is fixedly connected to the surface of the positioning plate 5062, and the other end of the connecting plate 5067 is hinged to the top of the fixed plate 5066. A contact pad 5068 is fixedly connected to the inner wall of the positioning plate 5062, and grooves distributed in equal rows are provided on the surface of the contact pad 5068. The positioning plate 5062 is an arc plate, and the contact pad 5068 is a rubber material component. Two positioning plates 5062 are symmetrically distributed on both sides of the track wheel 4. The bottom end of the piston plate 5063 is fixedly connected to a spring 5069 , and the bottom end of the spring 5069 is fixedly connected to the inner bottom wall of the second water tank 503 .

[0029] When the aqueous solution enters the second water tank 503, it will squeeze the piston plate 5063 to move downward, and under the action of the round rod 5064, it will push the movable plate 5065 to move downward synchronously. When the movable plate 5065 moves downward, under the action of the fixed plate 5066, the other end of the connecting plate 5067 will move horizontally, so that the angle between the connecting plate 5067 and the horizontal plane will gradually increase. Therefore, when the two movable plates 5065 move downward at the same time, under the action of the connecting plate 5067, the two positioning plates 5062 are pushed to move and approach each other, so that the contact pads 5068 on the inner walls of the two positioning plates 5062 contact the surface of the track wheel 4 and fix the track wheel 4, thereby improving the stability of the device when it is in static use. A one-way valve is provided on the surface of the water inlet pipe 504 to prevent the aqueous solution squeezed in the second water tank 503 from being squeezed and flowing back, thereby improving the stability during positioning.

[0030] like Figure 3 and Figure 5 As shown, a water pump 507 is fixedly connected to the top of the base 1, a three-way pipe 5071 is fixedly connected to the water inlet end of the water pump 507, and the water outlet end of the water pump 507 is connected to the first water tank 501. A connecting pipe 5072 is fixedly connected to the inner wall of the piston plate 5063, and the bottom end of the connecting pipe 5072 is observed to be in the second water tank 503, and the other two ends of the three-way pipe 5071 are respectively fixedly connected to the bottom ends of the corresponding connecting pipes 5072. The connecting pipe 5072 is a corrugated pipe.

[0031] A second switch solenoid valve is provided on the surface of the connecting pipe 5072, and the second switch solenoid valve is provided on the outside of the second water tank 503. When the positioning assembly 506 operates to position the track wheel 4, the second switch solenoid valve is in a closed state. When the device needs to be moved, the second switch solenoid valve is opened and the water pump 507 is started. At this time, the aqueous solutions in the two second water tanks 503 enter the three-way pipe 5071 through the corresponding connecting pipes 5072, and are poured into the first water tank 501 through the water outlet of the water pump 507. At this time, the two positioning plates 5062 release the positioning of the track wheel 4, and at the same time, the aqueous solution enters the first water tank 501 to increase the weight of the base 1, thereby increasing the stability of the device when moving.

[0032] When the utility model is in use, when the device needs to be moved, the installation rod 2 is pushed. At this time, under the action of the crawler wheel 4, the device moves as a whole. When the device moves to the desired position, the two first switch solenoid valves 505 in the positioning mechanism 5 are opened. At this time, the aqueous solution inside the first water tank 501 enters the inside of the two second water tanks 503 through the two water inlet pipes 504 at the same time under the action of gravity. When the aqueous solution enters the inside of the second water tank 503, it squeezes the piston plate 5063 to move downward, and pushes the moving plate 506 under the action of the round rod 5064. 5 move downward synchronously. When the moving plate 5065 moves downward, the other end of the connecting plate 5067 moves horizontally under the action of the fixed plate 5066, so that the angle between the connecting plate 5067 and the horizontal plane gradually increases. Therefore, when the two moving plates 5065 move downward at the same time, the two positioning plates 5062 are pushed to move and approach each other under the action of the connecting plate 5067, so that the contact pads 5068 on the inner walls of the two positioning plates 5062 contact with the surface of the track wheel 4 and fix the track wheel 4, thereby improving the stability of the device when it is in static use.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
