Description

Technical Field

[0001] The present invention relates to the technical field of self-powered pump stations, and in particular to a self-powered device and a self-powered system for a pump station. Background Art

[0002] A self-powered pumping station usually refers to a pumping station system with integrated power generation function. It generates electricity through a specific mechanism (such as photovoltaic power generation, wind power generation and other renewable energy generation methods), which is used to drive the water pumps in the pumping station to pump water. This design allows the pumping station to continue to operate without external power supply.

[0003] In actual application, the self-powered pump station is usually set up in desert or Gobi areas. When photovoltaic power generation is used as a self-powered device, since the photovoltaic panels are set outdoors, the sand and dust in the desert or Gobi areas can easily adhere to the surface of the photovoltaic panels. When the sand and dust attached to the surface of the photovoltaic panels is thick, it will not only affect the normal light energy conversion of the photovoltaic panels, but also affect the heat dissipation efficiency of the photovoltaic panels, and thus affect their normal movement. Therefore, manual regular dust removal is required, which is very cumbersome. Summary of the invention

[0022] Beneficial effects of the present invention:

[0023] (1) During the actual application of the photovoltaic assembly of the present invention, the dust layer attached to the surface of the photovoltaic panel body is cleaned regularly by the dust removal assembly. On the one hand, it can prevent the dust assembly from being too thick and affecting the normal light energy conversion of the photovoltaic panel body. On the other hand, it can prevent the dust from affecting the normal heat dissipation of the photovoltaic panel body. The present invention does not require manual regular cleaning of the dust layer on the surface of the photovoltaic panel body. The dust removal assembly can be used to automatically clean the dust layer, so that the self-powered device can be normally used in deserts or Gobi areas, while also ensuring the normal operation of the pump station;

[0024] (2) When the scraper is driven to slide toward the bottom of the photovoltaic panel body, the adjustment module first drives the wedge seat to slide through the driving rod, and the wedge seat can synchronously drive the baffle to slide toward the bottom of the photovoltaic panel body through the setting of the support, the first guide rod, the first spring, the L-shaped limit seat, the second guide rod, the second spring and the limit plate. When the scraper moves to the bottom of the photovoltaic panel body and abuts against the photovoltaic panel frame, as the adjustment module continues to drive the wedge seat to move, the scraper cannot move synchronously due to the obstruction of the photovoltaic panel frame, and the distance between the wedge seat and the baffle will decrease. During the sliding process of the support on the first guide rod, the first spring can be compressed and elastic force can be generated. In this process, the guide wheel rolls and abuts against the inclined guide surface to synchronously drive the baffle and the scraper to rise a certain distance, so that the limit plate can slide on the second guide rod and compress the second spring. When the bottom surface of the scraper rises to be flush with the surface of the photovoltaic panel frame, the rising process stops to discharge all the sand and dust deposited on the scraper.

[0025] (3) In the initial state of the present invention, the dustproof film is in a state of being wound on the roller. As the baffle moves toward the bottom of the photovoltaic panel body, the baffle can pull the dustproof film cover to be arranged on the photovoltaic panel body, thereby achieving a dustproof effect;

[0026] (4) When the scraper of the present invention slides toward the bottom of the photovoltaic panel body, the cam can be driven to rotate synchronously with the rotation of the roller. The cam drives the photovoltaic panel body to rotate synchronously by contacting with the top plate, thereby achieving a vibration effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figure 1 As shown, the present invention is a self-powered device, including a photovoltaic module 2, the photovoltaic module 2 is connected to the power cabinet 1 through a line 101, and the photovoltaic module 2 is used to transmit the converted electric energy to the power cabinet 1 through the line 101;

[0041] For details, please refer to Figure 2 The photovoltaic assembly 2 includes several groups of assembled and connected photovoltaic panel bodies 201, and the assembled photovoltaic panel bodies 201 are fixed in the photovoltaic panel frame 208; in this embodiment, based on the self-power supply demand of the pump station, several groups of photovoltaic panel bodies 201 are assembled and fixed in the photovoltaic panel frame 208 to support and protect the assembled photovoltaic panel bodies 201.

[0042] Among them, a dust removal component is arranged on the photovoltaic panel body 201, and the dust removal component is used to remove the dust attached to the photovoltaic panel body 201; it can be explained that during the actual application of the photovoltaic component 2 of this embodiment, the dust layer attached to the surface of the photovoltaic panel body 201 is cleaned regularly by the dust removal component. On the one hand, it can avoid the thick dust component affecting the normal light energy conversion of the photovoltaic panel body 201, and on the other hand, it can avoid the dust from affecting the normal heat dissipation of the photovoltaic panel body 201. This embodiment does not require manual regular cleaning of the dust layer on the surface of the photovoltaic panel body 201, and can be automatically cleaned by the dust removal component, so that the self-powered device can be normally used in deserts or Gobi areas, while also ensuring the normal operation of the pump station.

[0043] Example 2

[0044] Based on Example 1, please refer to Figure 3-Figure 5 The dust removal component includes a scraper 3 slidably arranged on the photovoltaic panel body 201. The scraper 3 is a conical structure, and its bottom surface is slidably fitted with the photovoltaic panel body 201. A baffle 301 is vertically fixedly arranged on the scraper 3, and the baffle 301 is connected to an adjustment module that drives it to slide along the surface of the photovoltaic panel body 201. It can be explained that in the initial state, the scraper 3 is located at the top position of the photovoltaic panel body 201. When the photovoltaic panel body 201 needs to be dusted, the scraper 3 is driven by the adjustment module to slide toward the bottom of the photovoltaic panel body 201. During the sliding process, the scraper 3 shovels up the dust attached to the surface of the photovoltaic panel body 201 to gather the dust in the space enclosed by the scraper 3 and the baffle 301. When the scraper 3 moves to the bottom of the photovoltaic panel body 201, the gathered dust can be discharged, thereby achieving the dust removal effect. After the dust removal is completed, the scraper 3 is driven to reset by the adjustment module.

[0045] Since the photovoltaic panel body 201 is fixed in the photovoltaic panel frame 208, the thickness of the photovoltaic panel frame 208 is greater than the thickness of the photovoltaic panel body 201, so that when the scraper 3 moves to the bottom of the photovoltaic panel body 201, part of the sand and dust will be deposited in the space formed by the scraper 3 and the photovoltaic panel frame 208. Figure 5-Figure 8The dust removal assembly also includes a lifting module connected to the baffle 301, and the lifting module is used to drive the baffle 301 to rise and fall; it can be explained that when the scraper 3 moves the bottom end of the photovoltaic panel body 201 and abuts against the photovoltaic panel frame 208, the scraper 3 is driven to rise a certain distance through the lifting module, so that the bottom surface of the scraper 3 is flush with the surface of the photovoltaic panel frame 208, and then the scraper 3 is continued to be driven to slide toward the bottom through the adjustment module to discharge all the sand and dust deposited on the scraper 3.

[0046] Specifically, the lifting module includes a guide wheel 409 symmetrically arranged on one side of the baffle 301, the guide wheel 409 is arranged on the side of the baffle 301 away from the scraper 3, and a wedge seat 4 is arranged on the side of the baffle 301 away from the scraper 3. The side of the wedge seat 4 close to the baffle 301 is provided with an inclined guide surface 401 corresponding to the guide wheel 409, and the wedge seat 4 is connected to the adjustment module through a driving rod 402, wherein a support 403 is fixedly arranged at one end of the wedge seats 4 on both sides away from each other, and a first guide rod 404 is slidably arranged in the support 403, and the first guide rod 404 is close to the baffle 30 1 is fixed to the L-shaped limit seat 406, a first spring 405 is provided on the first guide rod 404, one end of the first spring 405 is fixed to the L-shaped limit seat 406, and the other end is fixed to the support 403, a second guide rod 407 is fixedly arranged on the L-shaped limit seat 406, and both sides of the baffle 301 are respectively fixedly arranged with a limit plate 410 slidably connected to the second guide rod 407, a second spring 408 is provided on the second guide rod 407, one end of the second spring 408 is fixed to the L-shaped limit seat 406, and the other end is fixed to the limit plate 410; it can be explained that when driving When the scraper 3 slides toward the bottom of the photovoltaic panel body 201, the adjustment module first drives the wedge seat 4 to slide through the driving rod 402, and the wedge seat 4 can synchronously drive the baffle 301 to slide toward the bottom of the photovoltaic panel body 201 through the settings of the support 403, the first guide rod 404, the first spring 405, the L-shaped limit seat 406, the second guide rod 407, the second spring 408 and the limit plate 410. When the scraper 3 moves to the bottom of the photovoltaic panel body 201 and abuts against the photovoltaic panel frame 208, as the adjustment module continues to drive the wedge seat 4 to move, the scraper 3 is The photovoltaic panel frame 208 is blocked and cannot move synchronously, the distance between the wedge-shaped seat 4 and the baffle 301 will be reduced, and the support 403 can compress the first spring 405 and generate elastic force during the sliding process on the first guide rod 404. In this process, the guide wheel 409 rolls against the inclined guide surface 401 to synchronously drive the baffle 301 and the scraper 3 to rise a certain distance, so that the limit plate 410 can slide on the second guide rod 407 and compress the second spring 408. When the bottom surface of the scraper 3 rises to be flush with the surface of the photovoltaic panel frame 208, the rising process stops;

[0047] It should also be noted that this embodiment does not require the use of other servo drive devices to drive the scraper 3 and the baffle 301 to rise. When the scraper 3 abuts against the photovoltaic panel frame 208, the effect of automatic rising can be achieved, and the stability and synchronization are higher.

[0048] See also Figure 2-Figure 3 The adjustment module includes a driving box 204 fixedly arranged on one side of the photovoltaic panel frame 208, a screw is rotatably arranged in the driving box 204, the screw is fixed to the output end of the servo motor fixedly arranged on the outside of the driving box 204, a nut fixed to the driving rod 402 is spirally sleeved on the screw, and a guide box 203 is fixedly arranged on the other side of the photovoltaic panel frame 208, and a guide seat fixed to the driving rod 402 is slidably arranged in the guide box 203; it can be explained that when driving the wedge seat 4 to move, the present embodiment can drive the screw to rotate in the driving box 204 through the servo motor, and the nut can synchronously drive one side of the wedge seat 4 to move through the driving rod 402 during the movement of the screw, and the wedge seat 4 on the other side can drive the guide seat to slide in the guide box 203 through the driving rod 402, so as to improve the stability of the movement of the wedge seat 4.

[0049] See also Figure 4-Figure 7 as well as Figure 8-Figure 9 When the scraper 3 slides toward the bottom of the photovoltaic panel body 201, in order to prevent dust from falling onto the photovoltaic panel body 201, in this embodiment, a roller 304 is rotatably arranged on the top of the photovoltaic panel frame 208, and a dustproof film 302 is wound on the roller 304, and the end of the dustproof film 302 is fixed to the baffle 301; it can be explained that in the initial state, the dustproof film 302 is in a state of being wound on the roller 304. As the baffle 301 moves toward the bottom of the photovoltaic panel body 201, the baffle 301 can pull the dustproof film 302 to cover the photovoltaic panel body 201, thereby achieving a dustproof effect. During this process, the roller 304 can rotate synchronously to output the dustproof film 302.

[0050] As a further solution of this embodiment, when the dust-proof film 302 is output, in order to guide it, a guide roller 303 is rotatably arranged on one side of the rotating roller 304, and the dust-proof film 302 passes through the guide roller 303 and is fixed to the baffle 301; it can be explained that by setting the guide roller 303, the output of the dust-proof film 302 can be guided, thereby improving the stability of its output.

[0051] Furthermore, when the scraper 3 is reset upward from the bottom of the photovoltaic panel body 201, in order to rewind the output dust-proof film 302, in this embodiment, wheels 305 are fixedly arranged at both ends of the roller 304, and a rope 306 is wound on the wheel 305, and the end of the rope 306 is fixed to the counterweight 307; it can be explained that when the dust-proof film 302 is output from the roller 304, the roller 304 can synchronously drive the wheel 305 to rotate, so that the rope 306 can be gradually wound around the wheel 305, and the counterweight 307 can rise synchronously, and as the scraper 3 is reset upward, the wheel 305 can be driven to rotate in the opposite direction by the rope 306 under the action of the gravity of the counterweight 307, and the wheel 305 synchronously drives the roller 304 to rotate, so as to rewind the dust-proof film 302 around the roller 304, thereby achieving the reset and rewinding effect.

[0052] In order to facilitate the scraper 3 to scrape off the sand and dust attached to the photovoltaic panel body 201, in this embodiment, the photovoltaic assembly 2 also includes photovoltaic panel brackets 202 symmetrically arranged on both sides of the photovoltaic panel frame 208, and the bottoms of the photovoltaic panel brackets 202 on both sides are fixed by connecting frames, wherein one end of the photovoltaic panel brackets 202 on both sides is fixedly provided with a limit frame 209, and the driving box 204 and the guide box 203 are both rotatably connected to the limit frame 209 through the support shaft 205, wherein a rotating part is arranged on the other side of the photovoltaic panel bracket 202, and the rotating part is used to drive the driving box 204 and the guide box 203 to reciprocate around the support shaft 205; it can be explained that when the scraper 3 moves toward the bottom direction of the photovoltaic panel body 201, the driving box 204 and the guide box 203 can be driven by the rotating part to reciprocate around the support shaft 205, thereby achieving the effect of vibrating the photovoltaic panel body 201, so that the scraper 3 can scrape off the sand and dust attached to the photovoltaic panel body 201.

[0053] See also Figure 3 The rotating part includes a positioning frame 206 fixedly arranged on the other side of the photovoltaic panel bracket 202, and the top of the positioning frame 206 is fixed to the top plate 207, wherein a cam 308 is fixedly arranged on the end of the rotating wheels 305 on both sides away from the rotating roller 304, and the outer edge surface of the cam 308 is in sliding contact with the top plate 207; it can be explained that when the scraper 3 slides toward the bottom of the photovoltaic panel body 201, as the rotating roller 304 rotates, the cam 308 can be synchronously driven to rotate, and the cam 308 drives the photovoltaic panel body 201 to rotate synchronously by contacting with the top plate 207, thereby achieving a vibration effect.

[0054] The working principle of a self-powered device is as follows:

[0055] See also Figure 3-Figure 7When the photovoltaic panel body 201 is subjected to dust removal, the adjustment module drives the scraper 3 to slide toward the bottom of the photovoltaic panel body 201. During the sliding process, the scraper 3 scoops up the sand and dust attached to the surface of the photovoltaic panel body 201 to gather the sand and dust in the space enclosed by the scraper 3 and the baffle 301;

[0056] When the scraper 3 moves to the bottom of the photovoltaic panel body 201 and abuts against the photovoltaic panel frame 208, as the adjustment module continues to drive the wedge seat 4 to move, the scraper 3 is blocked by the photovoltaic panel frame 208 and cannot move synchronously, the distance between the wedge seat 4 and the baffle 301 will decrease, and the support 403 can compress the first spring 405 and generate elastic force during the sliding process on the first guide rod 404. During this process, the guide wheel 409 rolls and abuts against the inclined guide surface 401 to synchronously drive the baffle 301 and the scraper 3 to rise a certain distance, so that the limit plate 410 can slide on the second guide rod 407 and compress the second spring 408. When the bottom surface of the scraper 3 rises to be flush with the surface of the photovoltaic panel frame 208, the rising process stops, and the accumulated sand and dust can be discharged, and then the scraper 3 is driven to reset.
