Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel surface cleaning technology, and in particular relates to a dirt cleaning device for photovoltaic panel surfaces. Background Technology

[0002] After prolonged use, photovoltaic panels inevitably accumulate dirt on their surface. If this dirt is not cleaned, the panels may not be able to effectively absorb solar energy. Therefore, cleaning equipment is needed to clean the surface of the photovoltaic panels.

[0003] Existing cleaning devices typically use spraying to clean the surface of photovoltaic panels, followed by wiping to remove water stains. However, since the surface of photovoltaic panels usually contains heavily adhered dirt, spraying alone is insufficient to thoroughly clean the surface dirt, resulting in a significant amount of dirt remaining on the surface after cleaning, requiring multiple cleaning cycles and increasing cleaning costs. Therefore, we propose a dirt cleaning device for the surface of photovoltaic panels. Utility Model Content

[0004] The purpose of this invention is to provide a device for cleaning dirt on the surface of photovoltaic panels. Specifically, after placing the cleaning device on the photovoltaic panel, the pump on the right is activated to extract cleaning liquid from the tank and deliver it to a distribution pipe. The liquid is then sprayed from the nozzle, covering the surface of the photovoltaic panel. A motor is then activated, driving a large gear to rotate. This large gear, through two small gears and two rotating shafts, drives two turntables to rotate. The sponge brush pad, in conjunction with the cleaning liquid, then scrubs the photovoltaic panel. This method improves the cleaning effect and eliminates the need for multiple cleaning cycles. It solves the problem that existing cleaning devices typically use spraying to clean the photovoltaic panel surface, leaving a significant amount of dirt residue after cleaning, thus requiring multiple cleaning cycles and increasing cleaning costs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a device for cleaning dirt on the surface of photovoltaic panels, comprising a cleaning base, a liquid storage assembly on the top of the cleaning base, the liquid storage assembly including a liquid tank fixedly connected to the top of the cleaning base, two handles fixedly connected to the top of the liquid tank, a scrubbing assembly at the bottom of the cleaning base, the scrubbing assembly including a support plate fixedly connected to the inner wall of the cleaning base, two turntables below the support plate, several sponge scrubbing pads fixedly connected to the bottom of the turntables, a rotating shaft fixedly connected to the top of the turntables, a small gear fixedly connected to the top of the rotating shaft, a baffle fixedly connected to the center of the cleaning base, a motor fixedly connected to the inner wall of the baffle, a large gear fixedly connected to the bottom output end of the motor, and the large gear meshing with the small gear; when cleaning the lower part of the photovoltaic panel, the operator only needs to hold the handles to move the cleaning base, making operation more convenient.

[0007] Furthermore, the rotating shaft passes through the support plate and extends into the interior of the cleaning seat. The rotating shaft is rotatably connected to the support plate via a bearing. The pinion is positioned above the support plate, and the bottom of the turntable is lower than the bottom of the cleaning seat. Because the bottom of the turntable is lower than the bottom of the cleaning seat, the cleaning seat can avoid contact with the surface of the photovoltaic panel during the cleaning process.

[0008] Furthermore, a connecting assembly is provided on the front of the cleaning seat. The connecting assembly includes a fixing block fixedly connected to the front of the cleaning seat. A sleeve is hinged to the front of the fixing block. An internal threaded hole is opened inside the sleeve. A limiting plate is provided below the fixing block. The back of the limiting plate is fixedly connected to the front of the cleaning seat. The outer surface of the sleeve is in contact with the front of the limiting plate. Since the sleeve is hinged to the fixing block, it is convenient for the staff to adjust the position of the long rod and facilitates operation.

[0009] Furthermore, a water inlet pipe and a cleaning solution addition pipe are fixedly connected to the rear of the top of the liquid storage tank, and two partitions are fixedly connected to the inner wall of the liquid storage tank. A water tank is provided on the left side of the partitions, and a cleaning solution tank is provided on the right side of the partitions. By providing water tanks and cleaning solution tanks, water and cleaning solution are separated, which facilitates rinsing with water after subsequent cleaning.

[0010] Furthermore, a diversion pipe is provided on the back of the support plate, and several nozzles are fixedly connected to the bottom of the diversion pipe. A shielding shell is fixedly connected to the top back of the support plate. The back of the shielding shell is fixedly connected to the inner wall of the cleaning seat. Two brackets are fixedly connected to the outer surface of the diversion pipe, and the tops of the two brackets are fixedly connected to the top of the inner wall of the shielding shell. The brackets are used to support the diversion pipe and improve its stability.

[0011] Furthermore, two pumps are fixedly connected to the back of the storage tank. Each pump has a delivery pipe fixedly connected to its back storage port. The two pumps correspond to the water tank and the cleaning liquid tank, respectively. Each pump has a pumping pipe fixedly connected to its front inlet. The two pumping pipes are distributed inside the water tank and the cleaning liquid tank, respectively. One end of the delivery pipe passes through the cleaning seat and the shielding shell and extends to the top of the diversion pipe for fixed connection. The delivery pipe and the diversion pipe are interconnected. The two pumps are used to draw water and cleaning liquid, respectively, thus dividing the cleaning of the photovoltaic panel surface.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting up a scrubbing component, specifically involves placing the cleaning equipment on the photovoltaic panel, activating the liquid pump on the right to extract the cleaning liquid from the tank and deliver it to the distribution pipe, then spraying it out from the nozzle, so that the surface of the photovoltaic panel is covered with cleaning liquid. Then, the motor is activated to drive the large gear to rotate, which in turn drives the two turntables to rotate through the two small gears and two rotating shafts. The sponge scrubbing pad, in conjunction with the cleaning liquid, scrubs the photovoltaic panel. This method can improve the cleaning effect and eliminates the need for multiple cleaning cycles.

[0014] 2. This utility model uses a connecting component to connect the sleeve to a long rod via an internal thread. The worker then uses the long rod to move the cleaning seat to a higher position on the photovoltaic panel, making it easier to clean the higher position. The limiting plate limits the sleeve, preventing it from falling too much and avoiding contact between the sleeve and the photovoltaic panel surface when not connected to the long rod, thus protecting the photovoltaic panel surface from scratches.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-5As shown, this utility model is a device for cleaning dirt on the surface of photovoltaic panels, including a cleaning base 1. A liquid storage assembly 11 is provided on the top of the cleaning base 1. The liquid storage assembly 11 includes a liquid storage tank 111 fixedly connected to the top of the cleaning base 1. Two handles 112 are fixedly connected to the top of the liquid storage tank 111. A scrubbing assembly 12 is provided at the bottom of the cleaning base 1. The scrubbing assembly 12 includes a support plate 121 fixedly connected to the inner wall of the cleaning base 1. Two turntables 122 are provided below the support plate 121. Several sponge scrubbing pads 123 are fixedly connected to the bottom of the turntables 122. A rotating shaft 124 is fixedly connected to the top of the turntables 122. A small gear 125 is fixedly connected to the top of the rotating shaft 124. A baffle 12 is fixedly connected to the center of the cleaning base 1. 6. A motor 261 is fixedly connected to the inner wall of the baffle 126. A large gear 262 is fixedly connected to the bottom output end of the motor 261. The large gear 262 meshes with the small gear 125. After the cleaning equipment is placed on the photovoltaic panel, the liquid pump 143 on the right is started to draw out the cleaning liquid in the cleaning liquid tank 117 and deliver it to the diversion pipe 14. Then it is sprayed out from the nozzle 141, so that the surface of the photovoltaic panel is covered with cleaning liquid. Then the motor 261 is started to drive the large gear 262 to rotate. The large gear 262 will drive the two turntables 122 to rotate through the two small gears 125 and the two rotating shafts 124. The sponge brush pad 123 will cooperate with the cleaning liquid to brush the photovoltaic panel. This method can improve the cleaning effect and does not require multiple cleanings.

[0026] The rotating shaft 124 passes through the support plate 121 and extends into the interior of the cleaning seat 1. The rotating shaft 124 is rotatably connected to the support plate 121 through a bearing. The pinion 125 is located above the support plate 121. The bottom of the turntable 122 is lower than the bottom of the cleaning seat 1.

[0027] The front of the cleaning seat 1 is provided with a connecting component 13, which includes a fixing block 131 fixedly connected to the front of the cleaning seat 1. A sleeve 132 is hinged to the front of the fixing block 131. The sleeve 132 has an internal threaded hole. A limit plate 133 is provided below the fixing block 131. The back of the limit plate 133 is fixedly connected to the front of the cleaning seat 1. The outer surface of the sleeve 132 is in contact with the front of the limit plate 133. The sleeve 132 is connected to a long rod through the internal thread. Then, the staff uses the long rod to move the cleaning seat 1 to a high position of the photovoltaic panel, so as to facilitate cleaning of the high position. The limit plate 133 plays a limiting role in the sleeve 132, so that the sleeve 132 does not fall too much and avoids contact with the surface of the photovoltaic panel when the sleeve 132 is not connected to the long rod, thus protecting the surface of the photovoltaic panel from scratches.

[0028] A water inlet pipe 113 and a cleaning solution addition pipe 114 are fixedly connected to the top rear of the liquid storage tank 111. Two partitions 115 are fixedly connected to the inner wall of the liquid storage tank 111. A water tank 116 is provided on the left side of the partition 115, and a cleaning solution tank 117 is provided on the right side of the partition 115.

[0029] A diversion pipe 14 is provided on the back of the support plate 121. Several nozzles 141 are fixedly connected to the bottom of the diversion pipe 14. A shield 142 is fixedly connected to the top back of the support plate 121. The back of the shield 142 is fixedly connected to the inner wall of the cleaning seat 1. Two brackets 145 are fixedly connected to the outer surface of the diversion pipe 14. The tops of the two brackets 145 are fixedly connected to the top of the inner wall of the shield 142.

[0030] Two pumps 143 are fixedly connected to the back of the liquid storage tank 111. Each pump 143 has a delivery pipe 144 fixedly connected to its back liquid storage port. The two pumps 143 are respectively connected to the water tank 116 and the cleaning liquid tank 117. Each pump 143 has a pumping pipe fixedly connected to its front liquid inlet. The two pumping pipes are respectively distributed in the water tank 116 and the cleaning liquid tank 117. One end of the delivery pipe 144 passes through the cleaning seat 1 and the shield 142 and extends to the top of the diversion pipe 14 for fixed connection. The delivery pipe 144 and the diversion pipe 14 are interconnected.

[0031] One specific application of this embodiment is:

[0032] In use, connect the water inlet pipe 113 to the water pipe and fill the water tank 116 with water; deliver the cleaning solution to the cleaning solution tank 117 through the cleaning solution addition pipe 114, and then place the device on the photovoltaic panel so that the sponge scrubbing pad 123 on the turntable 122 contacts the surface of the photovoltaic panel. When cleaning the lower part of the photovoltaic panel, the operator only needs to hold the handle 112 to move the cleaning seat 1, and then start the liquid pump 143 on the right to draw out the cleaning solution in the cleaning solution tank 117 and deliver it to the diversion pipe 14 through the delivery pipe 144, and then spray it out from the nozzle 141 so that the surface of the photovoltaic panel is covered with cleaning solution. Then start the motor 261 to drive the large gear 262 to rotate, and the large gear 262 will drive the two small gears 125 to rotate at the same time. The small gears 125 will drive the turntable 122 to rotate through the rotating shaft 124. At this time, the sponge scrubbing pad 123 on the turntable 122 will work with the cleaning solution to scrub the photovoltaic panel. This method can improve the cleaning effect.

[0033] When it is necessary to clean the high part of the photovoltaic panel, the sleeve 132 is connected to the long rod through the internal thread. Then, the staff uses the long rod to move the cleaning seat 1 to the high part of the photovoltaic panel, which facilitates the cleaning of the high part. Since the sleeve 132 is hinged on the fixing block 131, the staff can easily adjust the position of the long rod and operate it. The limiting plate 133 plays a limiting role for the sleeve 132, so that the sleeve 132 will not fall too much and avoid the sleeve 132 from contacting the surface of the photovoltaic panel, thus protecting the surface of the photovoltaic panel from scratches.

[0034] Finally, after the photovoltaic panels are washed, stop the liquid pump 143 on the right and start the liquid pump 143 on the left to deliver water through the delivery pipe 144 to the diversion pipe 14, and then spray it out from the nozzle 141 to rinse the surface of the photovoltaic panels. This method can wash away the dirt after cleaning, and because it is directly connected to the water pipe, it can maintain a sufficient water supply.
