Description

Technical Field

[0001] The invention relates to the technical field of farmland irrigation equipment, and in particular to an energy-saving and environment-friendly farmland water conservancy device. Background Art

[0002] Irrigation is a technical measure to supplement the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water to provide a suitable growth environment for crops.

[0003] There are various ways of agricultural irrigation, including sprinkler irrigation, drip irrigation and channel irrigation. The water sources for channel irrigation include groundwater obtained through underground drilling wells, water stored in surface reservoirs and water flowing in canals. Groundwater usually only needs to be connected to the water outlet of the groundwater well by a water pipe, but the water stored in the surface reservoir and the water flowing in the canal usually need to be extracted by an extraction device before irrigating the farmland. The traditional extraction method is to extract water from water sources such as reservoirs or canals through a pump body. When pumping water, aquatic plants or debris in the water are easily sucked into the water pump, resulting in water pump loss. In the prior art, cutting teeth are set at the extraction end of the water pump to cut the aquatic plants and debris in the water. Although the aquatic plants and debris in the water can be cut, they are not processed. The aquatic plants or debris will gather at the pipe mouth of the pump body suction pipe, and it is easy to cause the pipe mouth to be blocked, resulting in a small amount of water sucked up, resulting in a small flow rate of water discharged into the farmland, which has a certain impact on the irrigation of the farmland.

[0024] The energy-saving and environmentally friendly farmland water conservancy device provided by the present invention is as follows: Figure 1 to Figure 3As shown, it includes a horizontally arranged support plate 1, a water pump 2 is fixedly connected to the support plate 1, a water inlet pipe 3 is connected to the bottom end of the water pump 2, the water inlet pipe 3 is a rigid pipe, and also includes a water inlet cylinder group 4, which is arranged below the water pump 2, the water inlet cylinder includes a first water inlet cylinder 41 and a second water inlet cylinder 42, the first water inlet cylinder 41 is rotatably sleeved on the outside of the second water inlet cylinder 42, there is a gap between the inner wall of the first water inlet cylinder 41 and the outer wall of the second water inlet cylinder 42, the water inlet end of the water inlet pipe 3 is fixedly connected to the top of the second water inlet cylinder 42, the crushing component 5 is arranged below the first water inlet cylinder 41, and is used to cut the debris and water plants entering the second water inlet cylinder 42, the scraping component 19 includes a plurality of scraping plates 191 and a first pulling rod 192, and a plurality of scraping The scraping plates 191 are all fittedly arranged below the crushing assembly 5, and a plurality of scraping plates 191 are fixedly connected to a first pulling rod 192 on one side away from each other. One end of the first pulling rod 192 passes through the first water inlet cylinder 41, and a horizontally arranged cutting blade 22 is fixedly connected to the side of the first pulling rod 192. The pulling assembly 20 includes a first wedge block 203, a second wedge block 204 and a return spring 205. One end of the first pulling rod 192 is located in the interval and is fixedly connected to the first wedge block 203, and the second wedge block 204 is fixedly connected to the outer side of the second water inlet cylinder 42. The return spring 205 is sleeved on the first pulling rod 192, one end of which is fixedly connected to the first water inlet cylinder 41, and the other end is fixedly connected to the first wedge block 203.

[0025] The energy-saving and environment-friendly farmland water conservancy device of the present invention is used by placing the support plate 1 on the water body, turning on the water pump 2 to extract the water flow in the water body through the water inlet pipe 3. When extracting, it is inevitable that the debris or aquatic plants in the water will move into the water inlet cylinder group 4. The water inlet cylinder group 4 provided by the present invention is composed of a first water inlet cylinder 41 and a second water inlet cylinder 42 that are rotatably sleeved, and the water inlet pipe 3 and the second water inlet cylinder 42 are fixedly connected. The first water inlet cylinder 41 is rotated by an external drive, and the first water inlet cylinder 41 will drive the crushing component 5 provided at the bottom to cut off the debris and aquatic plants in the water, so as to prevent the aquatic plants and fixed debris from blocking the second water inlet cylinder 42. The first pulling rod 192 is pulled by the pulling component 20, so that the first pulling rod 192 drives the scraper plate 191 to scrape the crushing component 5, thereby preventing the crushed debris from accumulating under the second water inlet cylinder 42 and causing blockage of the second water inlet cylinder 42, and because a cutting blade 22 is provided on the side of the first pulling rod 192, and the first pulling rod 192 and the first water inlet cylinder 41 rotate synchronously, the cutting blade 22 can be used to further enhance the crushing ability of debris and aquatic plants in the water, thereby preventing accumulation under the second water inlet cylinder 42 and causing blockage of the second water inlet cylinder 42, thereby facilitating the water pump 2 to normally extract water, so as to facilitate the normal irrigation work.

[0026] In the present embodiment, it is taken into consideration that when the first crushing teeth 55 provided on the first support rod 52 and the second support rod 53 crush the water plants and debris in the water, some of the debris or water plants will stick to the bottom of the first support rod 52 and the second support rod 53. In the long run, this will cause too much debris to stick to the bottom of the first support rod 52 and the second support rod 53, which will have a certain impact on the normal rotation of the first support rod 52 and the second support rod 53, and may also cause a certain amount of accumulation, which is not conducive to the water suction work of the water pump 2.

[0027] The scraping assembly 19 is driven by the pulling assembly 20 to scrape the bottom of the first support rod 52 and the second support rod 53, and one end of the first pulling rod 192 is fixedly connected to the second pulling rod 201, and one end of the second pulling rod 201 is fixedly connected to the third pulling rod 202. The third pulling rod 202 is slidably arranged in the first water inlet cylinder 41. In the interval formed by the inner wall of the first water inlet cylinder 41 and the outer wall of the second water inlet cylinder 42, the first wedge block 203 and the second wedge block 204 are matched. When the first water inlet cylinder 41 rotates, the first wedge block 203 and the second wedge block 204 are matched, and the first wedge block 203 is moved to Move away from the second wedge block 204, and the third pull rod 202 will be pushed outward and the return spring 205 will be squeezed. Since the third pull rod 202 is connected to the first pull rod 192 through the second pull rod 201, the first pull rod 192 will pull the scraper plate 191 to scrape the first support rod 52 and the second support rod 53. The clever design allows the crushing part and the scraping part to complement each other and work together to clean up the aquatic plants and debris located at the second water inlet cylinder 42, so as to avoid the crushed debris from accumulating under the second water inlet cylinder 42 and causing blockage, so as to facilitate the normal operation of the water pump 2 to absorb water.

[0028] In this embodiment, a plurality of second wedge blocks 204 are provided, and the plurality of second wedge blocks 204 are evenly distributed along the circumference of the outer wall of the second water inlet cylinder 42. The plurality of second wedge blocks 204 increase the frequency of matching with the first wedge block 203, thereby increasing the scraping frequency of the scraping plate 191, and better scraping the weed segments accumulated on the first support rod 52 and the second support rod 53.

[0029] Preferably, Figure 1 to Figure 3As shown, the crushing assembly 5 includes a carrying ring 51, a first support rod 52 and a second support rod 53. The carrying ring 51 is arranged below the first water inlet cylinder 41. The first support rod 52 and the second support rod 53 are cross-arranged and are both fixedly connected to the carrying ring 51. The carrying ring 51 is horizontally fixed below the first water inlet cylinder 41 through the carrying rod 54 and coincides with the axis of the first water inlet cylinder 41. A plurality of first crushing teeth 55 are arranged. The first support rod 52 and the second support rod 53 are both provided with first crushing teeth 55 on their sides. A plurality of scraping plates 191 are fittedly arranged at the bottom of the first support rod 52 and the second support rod 53.

[0030] The carrying ring 51 supports the first support rod 52 and the second support rod 53, and the first support rod 52 and the second support rod 53 are cross-arranged. When the carrying ring 51 rotates, the first crushing teeth 55 arranged on the first support rod 52 and the second support rod 53 can better cut the aquatic plants and solid debris in the water body, and cut the debris and aquatic plants in the water body to avoid the water inlet pipe 3 being blocked by the aquatic plants.

[0031] Preferably, Figure 7 As shown, the scraping plate 191 is arranged in an arc shape, and a plurality of scraping plates 191 are fixedly connected with a striking rod 23 on one side close to each other, and a striking ball 24 is fixedly connected with the end of the striking rod 23 away from the scraping plate 191, and the striking rod 23, the striking ball 24, the scraping plate 191, and the first pulling rod 192 are all made of stainless steel, and the striking ball 24 is a hollow ball.

[0032] In this embodiment, the scraping plate 191 is set to an arc shape so that the scraped debris can be better gathered, thereby improving the scraping effect. When adjacent hitting balls 24 collide, vibration force will be generated, which will be transmitted to the scraping plate 191 and the first pulling rod 192, and some debris will be shaken off the scraping plate 191 and the first pulling rod 192. The hitting rod 23, hitting ball 24, scraping plate 191, and first pulling rod 192 are all made of stainless steel. Because they are set underwater, rust is avoided to affect the normal use of the device. The hitting ball 24 is a hollow ball because the hollow ball 24 will generate greater vibration force when colliding.

[0033] Preferably, Figure 1 to Figure 5 As shown, a third support rod 6 and a fourth support rod 7 are fixedly connected below the second water inlet cylinder 42 , the third support rod 6 and the fourth support rod 7 are cross-arranged, and second crushing teeth 8 are provided on the sides of the third support rod 6 and the fourth support rod 7 .

[0034] A third support rod 6 and a fourth support rod 7 are arranged in the second water inlet cylinder 42, and the third support rod 6 and the fourth support rod 7 are also arranged crosswise. Although the third support rod 6 and the fourth support rod 7 are fixedly arranged in the second water inlet cylinder 42, there is only a certain interval between the bearing ring 51 and the bottom end of the second water inlet cylinder 42. When the first water inlet cylinder 41 rotates, the first support rod 52 and the second support rod 53 will crush the waterweed and debris through the first crushing teeth 55. When the first water inlet cylinder 41 rotates, the second water inlet cylinder 42 relatively rotates in the opposite direction. Considering that there are some fixed conditions in the water body, For debris such as dead branches, it is difficult to crush and cut the dead branches with the crushing teeth arranged on the first support rod 52 and the second support rod 53, or the length of the dead branches after being cut is still relatively large, and the long dead branches will cause a certain degree of blockage when entering the water inlet pipe 3. In this embodiment, when the dead branches are located between the first crushing teeth 55 and the second crushing teeth 8, the first crushing teeth 55 and the second crushing teeth 8 can better break the dead branches, and the second crushing teeth 8 located on the third support rod 6 and the fourth support rod 7 and the first crushing teeth 55 located on the first support rod 52 and the second support rod 53 are located on different sides.

[0035] Preferably, Figure 1 to Figure 4 As shown, it also includes a horizontally arranged support plate 1, a water pump 2 is fixedly connected to the support plate 1, a telescopic sleeve 9 is fixedly connected to the top of the water inlet pipe 3, one end of the telescopic sleeve 9 is connected to the water inlet of the water pump 2, and fixed rods 10 are vertically fixedly connected to the bottom corners of the bottom side of the support plate 1, and a plurality of fixed rods 10 are provided with rolling wheels 11 at the bottom. When the telescopic sleeve 9 is fully compressed, the bottom of the bearing ring 51 is higher than the bottom of the rolling wheel 11, a protection box 12 is fixedly connected to the bottom of the support plate 1, and the bottom of the protection box 12 is opened, a sliding plate 13 is fixedly sleeved on the water inlet pipe 3, and the sliding plate 13 is vertically slidably arranged along the inner wall of the protection box 12, and a vertically arranged cylinder 14 is fixedly connected to the bottom of the support plate 1, and the output end of the cylinder 14 is fixedly connected to the sliding plate 13.

[0036] In this embodiment, considering that when absorbing water in the canal, the support plate 1 must be lowered into the canal at first, and the user pulls the support plate 1. The rolling wheel 11 arranged at the bottom of the support plate 1 will move the support plate 1 on the side slope of the canal, so as to facilitate the lowering of the support plate 1 into the canal. In addition, considering that the depth during water absorption may be different, the water inlet end of the water pump 2 is connected to the water inlet pipe 3 through the telescopic tube group, and the water inlet tube group 4 and the water inlet pipe 3 must also be protected when the support plate 1 is lowered. Therefore, a protection box 12 is provided for protection, and when the telescopic sleeve 9 is fully compressed, the bottom of the load-bearing ring 51 is higher than the bottom of the rolling wheel 11, so that the water inlet tube group 4 is prevented from contacting the side slope of the canal when the support plate 1 is lowered. The bottom of the protection box 12 is opened, and the sliding plate 13 is pushed by the cylinder 14 to control the sliding plate 13 to slide up and down in the protection box 12. The sliding plate 13 will drive the water inlet pipe 3 to move and stretch the telescopic sleeve 9.

[0037] Preferably, Figure 1 to Figure 4 As shown, a driving assembly 15 is fixedly connected to the bottom of the sliding plate 13, and the driving assembly 15 includes a motor 151, which is vertically arranged. A gear 152 is fixedly connected to the output end of the motor 151, and a ring gear 153 is sleeved on the outer side of the first water inlet cylinder 41, and the ring gear 153 is meshed with the gear 152.

[0038] In this embodiment, the sliding plate 13 supports the motor 151, and the motor 151 drives the first gear 152 to rotate. Gear teeth are sleeved on the outside of the first water inlet cylinder 41, and the first gear 152 is engaged with the gear teeth to drive the first water inlet cylinder 41 to rotate, providing a power source for the rotation of the first water inlet cylinder 41. When the water pumping working state is not in progress, the water inlet cylinder group 4 and the driving assembly 15 are all located in the protective box 12 for protection.

[0039] Preferably, Figure 1 As shown, a buoyancy airbag 16 is fixedly provided under the support plate 1, and the buoyancy airbag 16 is used to make the support plate 1 float on the water surface. A support column 17 is fixedly connected to the top of the support plate 1, and a solar panel 18 is fixedly connected to the top of the support column 17. The solar panel 18 is used to generate electricity to provide energy for the cylinder 14 and the motor 151. A hook ring 21 is fixedly provided on one side of the support plate 1, and a draw rope is buckled on the hook ring 21.

[0040] In this embodiment, the support plate 1 is floated on the water surface by a buoyancy airbag 16 arranged at the bottom of the support plate 1. The support plate 1 supports the support column 17, and the support column 17 supports the solar panel 18. The solar panel 18 generates electricity to provide the required energy for the cylinder 14 and the motor 151, thereby saving energy. A hook ring 21 is arranged on one side of the support plate 1 and a pull rope is buckled on the hook ring 21. The user slowly transports the support plate to the water surface of the water channel to be drawn water by pulling the rope.

[0041] The method of using the energy-saving and environmentally friendly farmland water conservancy device of the present invention is as follows: The user connects the water pipe to the water outlet end of the water pump 2, makes the support plate 1 flush with the side slope of the canal by pulling the rope, and slowly lowers the rope to make the support plate 1 move up and down on the side slope of the canal under the action of gravity until the support plate 1 moves down to the canal water body, and the buoyancy airbag 16 makes the support plate 1 float on the water body.

[0042] The sliding plate 13 is pushed by the cylinder 14 to control the sliding plate 13 to slide up and down in the protection box 12. The sliding plate 13 will drive the water inlet pipe 3 to move, stretch the telescopic sleeve 9, and insert the water inlet tube group 4 set at the bottom of the water inlet pipe 3 into the water body.

[0043] At this time, the motor 151 is turned on to drive the gear 152 to rotate. The gear 152 is meshed with the ring gear 153 mounted on the first water inlet cylinder 41, so that the first water inlet cylinder 41 rotates, and the first water inlet cylinder 41 drives the bottom supporting ring 51 to rotate. When the supporting ring 51 rotates, the first support rod 52 and the first crushing teeth 55 arranged on the second support rod 53 can better cut the aquatic plants and solid debris in the water body. Although the third support rod 6 and the fourth support rod 7 are fixedly arranged in the second water inlet cylinder 42, there is only a certain interval between the supporting ring 51 and the bottom end of the second water inlet cylinder 42. When the first water inlet cylinder 41 rotates, the second water inlet cylinder 42 rotates in the opposite direction relatively. The first crushing teeth 55 and the second crushing teeth 8 are used to crush the debris in the water.

[0044] When the first water inlet cylinder 41 rotates, the first wedge block 203 and the second wedge block 204 fit together, and the first wedge block 203 will move away from the second wedge block 204. At this time, the third pull rod 202 will be pushed outward and the return spring 205 will be squeezed. Because the third pull rod 202 is connected to the first pull rod 192 through the second pull rod 201, the first pull rod 192 will pull the scraper plate 191 to scrape the first support rod 52 and the second support rod 53. The clever design allows the crushing part and the scraping part to complement each other and work together to clean up the water plants and debris located at the second water inlet cylinder 42, so as to facilitate the normal operation of the water pump 2 to absorb water. After the water intake work is completed, the water inlet cylinder group 4 and the drive assembly 15 are all located in the protective box 12 for protection through the cylinder 14.

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