Description

Technical Field

[0001] This utility model relates to the field of irrigation hose technology, and in particular to an irrigation hose water flow buffer. Background Technology

[0002] When farmland is dry, it is irrigated. However, due to structural problems with the irrigation system, when seeds are not yet sown, the irrigated land can be washed away, creating pits and uneven water flow, affecting irrigation quality and impacting cultivation. After sowing, if the land is dry, water is used to irrigate the sown fields to promote seed germination and growth. However, during irrigation, the strong water flow can wash away sown seeds and fertilizer, and the washed-out soil can cover the surrounding sown land, causing excessive soil cover that hinders seedling emergence, resulting in missing or sparse seedlings. To address this problem, application number: 2016212056 was submitted. 91.X discloses a water flow buffer for irrigation hoses, including a fixing head, an outlet pipe, and spray heads. The fixing head is installed at one end of the outlet pipe, and multiple identical spray heads are installed at the other end. Each spray head is a hollow, flat rectangular body that becomes flat after being filled with water. The front end of the hollow body is closed, and the rear end is connected to the outlet of the outlet pipe. Spray holes are evenly distributed on the front and top of the rectangular hollow body. The fixing head is equipped with a fixing device for fixing the irrigation hose. This device has a simple, novel, and unique structure, is easy to install and use, easy to produce, low in cost, and has good performance. It provides uniform irrigation, eliminates puddles, saves labor and seeds, saves water and increases yield, and has good social and economic benefits.

[0003] The aforementioned patent discloses a water flow damper for irrigation hoses, which can achieve water flow diversion and buffering by setting multiple parallel water nozzles and water holes. However, it still has shortcomings in use: it only buffers the water flow by diverting it in a single way when the water flow is discharged. When the water flow impact force is large, it does not play an effective buffering role. When the water is sprayed onto the ground through multiple water holes, small water puddles will still be formed. In view of the above, this application proposes a water flow damper for irrigation hoses. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water flow buffer for irrigation hoses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water flow damper for irrigation hoses includes a three-part spray head, a fixing head above the three-part spray head, and multiple spray holes on the front side of the three-part spray head. Two fixing straps are fixedly connected to the left side of the fixing head. By cooperating with the fixing head and the fixing straps, the entire device can be secured to the water outlet of the irrigation hose. The device also includes:

[0007] The water flow dispersion and buffering mechanism is located between the top of the three-part spray head and the bottom of the fixed head. The water flow dispersion and buffering mechanism is used to buffer and decompress the water flow.

[0010] The sealing mechanism consists of two sets, which are respectively installed in the first internal threaded sleeve and the second internal threaded sleeve.

[0011] Preferably, the water flow dispersion and buffering mechanism includes an installation pipe, with a first internal threaded sleeve and a second internal threaded sleeve threaded onto the installation pipe. A rotating shaft is rotatably installed between the inner walls of both sides of the installation pipe. Multiple water impellers are fixedly connected to the outer side of the rotating shaft in a ring shape. As the water impellers rotate, they can disperse and deflect the impact force of the water flow. A first diversion filter plate located below the rotating shaft is fixedly installed inside the installation pipe. The first diversion filter plate is used to divert and deflect the water flow. A support block is embedded and fixedly installed on the top of the first diversion filter plate. A positioning tube is fixedly connected to the top of the support block.

A V-shaped force-distributing plate is fixedly connected to the top of the positioning rod. The positioning rod and the positioning tube cooperate to provide a vertical guiding effect for the V-shaped force-distributing plate. The spring force can effectively buffer and deflect the impact force of the water flow. Second diversion filter plates are embedded and fixedly installed on both sides of the top of the V-shaped force-distributing plate. The second diversion filter plates are used to divert and deflect the water flow.

[0012] Preferably, the sealing mechanism includes support rings, with two support rings fixedly fitted inside the first internal threaded sleeve and the second internal threaded sleeve, respectively. Sealing rings are glued and fixed to the sides of the two support rings that are close to each other. The sides of the two sealing rings that are close to each other are in close contact with the top and bottom ends of the mounting pipe, respectively. The sealing rings enable a sealed connection between the mounting pipe and the first internal threaded sleeve and the second internal threaded sleeve. A flow guide is fixedly fitted inside the upper support ring, and the opening of the flow guide is aligned with the front water turbine blade.

[0013] Preferably, circular holes are provided on the inner walls of both sides of the mounting tube, and sealed bearings are fixedly fitted inside the circular holes. The inner ring of the sealed bearing is fixedly connected to the outer side of the rotating shaft, and the sealed bearing serves to allow the rotating shaft to rotate and be installed.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-2 A water flow damper for irrigation hose includes a three-part spray head 1, a fixing head 2 above the three-part spray head 1, and multiple spray holes 101 on the front side of the three-part spray head 1. Two fixing straps 3 are fixedly connected to the left side of the fixing head 2. By cooperating with the fixing head 2 and the fixing straps 3, the entire device can be bound to the water outlet of the irrigation hose. Two button holes 301 are opened on the front side of the fixing straps 3, and two buttons are fixedly connected to the rear side of the fixing head 2. The buttons cooperate with the corresponding button holes 301.

[0027] In this implementation scheme: The existing device {application number}: 201621205691.X discloses a water flow buffer for irrigation hoses. The three-part spray head 1, fixing head 2, fixing belt 3, button hole 301 and button in this application adopt the same technical means as in this prior art. This technical means will not be described in detail here. Regarding the main body of this prior art, this application makes further improvements. For details, please refer to the disclosed technology below. In order to solve the technical problems existing in this prior art, such as the "buffering by a single diversion method when the water is discharged" disclosed in the background technology above, when the water flow impact force is large, it does not play an effective buffering effect. When the water is sprayed out of multiple spray holes to the ground, small water puddles will still be formed. In combination, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, a water flow dispersion buffer mechanism 4 is added to this application.

[0028] Furthermore:

[0029] Reference Figure 1-4 A water flow damper for irrigation hoses also includes:

[0030] The water flow dispersion and buffer mechanism 4 is set between the top of the three-part spray head 1 and the bottom of the fixed head 2. The water flow dispersion and buffer mechanism 4 is used to buffer and unload the water flow.

[0031] The first internal threaded sleeve 102 is connected and fixed to the top of the three-part spray head 1, and is sleeved on the water flow dispersion buffer mechanism 4.

[0032] The second internal threaded sleeve 202 is connected and fixed to the bottom of the fixed head 2 and sleeved on the water flow dispersion and buffer mechanism 4. Through the cooperation of the first internal threaded sleeve 102 and the second internal threaded sleeve 202, the connection between the water flow dispersion and buffer mechanism 4, the three-part spray head 1, and the fixed head 2 can be realized.

[0033] The water flow dispersion and buffering mechanism 4 includes an installation pipe 401, a first internal threaded sleeve 102 and a second internal threaded sleeve 202 both threaded onto the installation pipe 401. External threads are provided at the top and bottom of the outer side of the installation pipe 401. Internal threads are provided inside the first internal threaded sleeve 102 and the second internal threaded sleeve 202, with the external threads meshing with the corresponding internal threads. A rotating shaft 402 is rotatably mounted between the inner walls of both sides of the installation pipe 401. Circular holes are provided on the inner walls of both sides of the installation pipe 401. A sealed bearing is fixedly fitted inside the circular hole. The inner ring of the sealed bearing is fixedly connected to the outer side of the rotating shaft 402. The sealed bearing serves to allow the rotating shaft 402 to rotate. Multiple water turbine blades 403 are fixedly connected in a ring shape to the outer side of the rotating shaft 402. As the water turbine blades 403 rotate, they can disperse and relieve the impact force of the water flow. A first diversion filter plate 407 located below the rotating shaft 402 is fixedly fitted inside the installation pipe 401. The first diversion filter plate 407 is used to divert and relieve the force of the water flow. A support block 408 is fixedly installed on the top of the filter plate 407. A positioning tube 409 is fixedly connected to the top of the support block 408. The support block 408 supports the positioning tube 409. A positioning rod 410 is slidably sleeved inside the positioning tube 409. A spring 411 is fixedly connected between the bottom end of the positioning rod 410 and the top of the support block 408. A V-shaped force-shaping plate 404 is fixedly connected to the top end of the positioning rod 410. The positioning rod 410 and the positioning tube 409 cooperate to support the V-shaped force-shaping plate 404. To achieve the effect of vertical guidance, the elastic force of spring 411 can effectively buffer and unload the impact force of water flow. The top two sides of the V-shaped force dividing plate 404 are both embedded and fixed with second flow dividing filter plates 406. The second flow dividing filter plates 406 are used to divide and unload water flow. The top two sides of the V-shaped force dividing plate 404 are provided with mounting holes 405. The side of the two mounting holes 405 that is far away from each other is set as an opening. The inner wall of the mounting hole 405 is fixedly connected to the outer side of the corresponding second flow dividing filter plate 406.

[0034] The sealing mechanism consists of two sets, which are respectively installed in the first internal threaded sleeve 102 and the second internal threaded sleeve 202. The sealing mechanism includes a support ring 5, and the two support rings 5 ​​are respectively fixedly sleeved in the first internal threaded sleeve 102 and the second internal threaded sleeve 202. A sealing ring 6 is glued and fixed on the side of the two support rings 5 ​​that is close to each other. The side of the two sealing rings 6 that is close to each other is in close contact with the top and bottom ends of the installation tube 401, respectively. The setting of the sealing ring 6 can realize the sealing connection between the installation tube 401 and the first internal threaded sleeve 102 and the second internal threaded sleeve 202. A flow guide is fixedly sleeved in the upper support ring 5. The opening of the flow guide is aligned with the front water turbine blade 403, so that the water flow can directly impact the front water turbine blade 403.

[0035] In this implementation scheme: water discharged from the outlet of the irrigation hose impacts the water impeller 403 on the front side. The water impeller 403 drives the rotating shaft 402 to rotate, and the rotating shaft 402 drives multiple water impellers 403 on it to rotate, which disperses and buffers the impacting water. The dispersed water impacts the V-shaped force distribution plate 404, causing it to move downward. The V-shaped force distribution plate 404 drives the positioning rod 410 to slide downward in the positioning tube 409 and compress the spring 411. The elastic force of the spring 411 is used to buffer and de-stress the impact force. At the same time, the water impacting the V-shaped force distribution plate 404 is discharged downward through two second diversion filter plates 406, which performs preliminary diversion and buffering of the water. The diverted water is discharged through the first diversion filter plate 407 and enters the three-part spray head 1 through the first internal threaded sleeve 102. The first diversion filter plate 407 performs further diversion and buffering of the water. The water in the three-part spray head 1 is diverted and discharged again through multiple spray holes 101, thereby effectively achieving the effect of water flow buffering.

[0036] It should be noted that the water turbine blade 403, rotating shaft 402, V-shaped force distribution plate 404, positioning rod 410, positioning tube 409, spring 411, second diversion filter plate 406 and first diversion filter plate 407 are all made of lightweight plastic, which can avoid rusting due to long-term water impact and ensure the stability of the entire device.

[0037] Working principle: In use, the entire device is secured to the water outlet of the irrigation hose by means of the fixing strap 3, button hole 301, button, and fixing head 2. The binding method has been disclosed in the patent application number: 201621205691.X. When water is discharged from the water outlet of the irrigation hose and supplied through the fixing head 2, the second internal threaded sleeve 202, and the guide cover, the water impacts the water impeller 403 on the front side, causing it to rotate. The water impeller 403 drives the rotating shaft 402 to rotate. The rotating shaft 402 drives multiple water turbine blades 403 to rotate. As the water turbine blades 403 rotate, they disperse and buffer the impacting water. The dispersed water impacts the V-shaped force distribution plate 404, and the impact force causes the V-shaped force distribution plate 404 to move downwards. The V-shaped force distribution plate 404 causes the positioning rod 410 to slide downwards within the positioning tube 409. As the positioning rod 410 moves downwards, it compresses the spring 411. Under the elastic force of the spring 411, the impact is reduced. The force is buffered and unloaded. At the same time, the water impacting the V-shaped force-sharing plate 404 is discharged downward through the two second diversion filter plates 406. The second diversion filter plates 406 perform initial diversion and buffering of the water. The diverted water is discharged through the first diversion filter plate 407 and enters the three-part spray head 1 through the first internal threaded sleeve 102. The first diversion filter plate 407 performs secondary diversion and buffering of the water. The water in the three-part spray head 1 is diverted and discharged again through multiple spray holes 101. The water discharged from the water outlet of the irrigation water belt is dispersed and buffered by the rotation of the water wheel blade 403, the force-sharing buffering of the V-shaped force-sharing plate 404 and the spring 411, the initial diversion and buffering of the second diversion filter plate 406, the secondary diversion and buffering of the first diversion filter plate 407, and the secondary diversion of the three-part spray head 1. The combination of these multiple buffering and unloading methods can effectively achieve the effect of water flow buffering. Compared with single diversion buffering, the buffering effect is effectively improved through multiple buffering and unloading, which can effectively reduce the situation where the water is washed out of the water pit due to the large impact force of the water flow.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
