Description

Technical Field

[0001] The invention relates to the technical field of sprinkler irrigation, in particular to a water-saving high-pressure water spraying device. Background Art

[0002] Sprinkler irrigation is an advanced irrigation method that uses special equipment (such as power machines, water pumps, pipes, etc.) to pressurize water or utilize natural head drop to deliver pressurized water to the irrigation area, and then sprays it into the air through nozzles to form tiny water droplets that are evenly sprinkled on the field for irrigation.

[0003] Sprinkler irrigation equipment consists of water inlet pipes, pumps, water pipes, distribution pipes and nozzles. It can be fixed, semi-fixed or mobile. It has the advantages of saving water, not destroying soil structure, regulating ground climate and not being restricted by terrain.

[0004] The underground sprinkler irrigation equipment is a type of fixed sprinkler irrigation equipment, except that its water pipes are buried under the soil, and the sprinkler pipes adopt an automatic telescopic structure. When spraying water, the water pressure is used to extend the sprinkler pipe and the nozzle out of the soil. After the spraying is finished, the nozzle and the sprinkler pipe are retracted under the soil by their own gravity.

[0005] In the related art, for example, Chinese patent CN205993254U discloses a multi-section telescopic irrigator. During the use of the multi-section telescopic irrigator, when water passes through the tee and enters the multi-section telescopic irrigator through the inlet, when the water reaches a certain pressure, the inner tube is lifted up, the first tension spring and the second tension spring are stretched, and the spring is compressed. When the water pressure increases, the middle tube is also lifted up. During this process, the first tension spring and the second tension spring continue to be stretched, and the spring continues to be compressed, and water is sprayed out from the nozzle. When the water source is turned off, the water pressure drops, and the inner tube and the middle tube automatically fall back under the action of the first tension spring, the second tension spring, and the spring.

[0006] Although the above-mentioned multi-section telescopic irrigation device can improve the water spraying efficiency to a certain extent, it is found in actual use that since the water spray pipe is buried underground and adopts a two-layer or multi-layer casing structure, the water spray pipe will inevitably bring in some mud when it is retracted. After multiple extensions and retractions, it is easy for the soil to block the expansion joints of the multi-layer casing type water spray pipe, making it impossible for the water spray pipe to be smoothly extended and retracted, affecting the irrigation of crops. Summary of the invention

[0007] Based on this, it is necessary to provide a water-saving high-pressure water spraying equipment to address the problem of poor reliability of current irrigation equipment during use.

[0008] The above purpose is achieved through the following technical solutions:

[0009] A water-saving high-pressure water spraying device, the water-saving high-pressure water spraying device comprises an irrigation device, the irrigation device comprises a base pipe, a telescopic pipe, a first elastic member and a second elastic member, the base pipe is configured to receive water from the outside; the telescopic pipe is vertically arranged on the circumferential side wall of the base pipe, is connected to the base pipe, and can be telescopic along its own axis direction; the telescopic pipe comprises a top pipe, a middle pipe and a bottom pipe which are slidably sleeved in sequence from the inside to the outside, the bottom pipe and the middle pipe, the middle pipe and the top pipe are all stoppered, and the bottom pipe and the A gap for water outlet is formed between the middle tubes, and a nozzle is provided on the top of the top tube, and the nozzle is configured to spray water for irrigation; the first elastic member is inserted into the top tube and connected between the top tube and the base tube, and under the action of the first elastic member, the top tube has a tendency to move toward the direction approaching the base tube; the second elastic member is inserted into the middle tube and connected between the middle tube and the base tube, and under the action of the second elastic member, the middle tube has a tendency to move away from the base tube;

[0010] When the top pipe is extended outward under the action of water, the middle pipe can be extended outward synchronously following the top pipe under the pushing of the second elastic member, and when the middle pipe is extended outward to the limit position, the upward end thereof is above the ground.

[0011] Furthermore, the irrigator further comprises an annular filter screen, which is sleeved on the outside of the second elastic member, connected between the middle pipe and the base pipe, and configured to receive water from the base pipe.

[0012] Furthermore, there are multiple irrigators.

[0013] Furthermore, the water-saving high-pressure water spraying equipment also includes a water supply system, and the water supply system is configured to supply water to all the irrigators at the same time.

[0014] Furthermore, the irrigation device also includes a friction disk, which is coaxially inserted into the middle tube and is in friction contact with the middle tube; the top end of the annular filter is arranged at the bottom of the friction disk, and the bottom end is arranged on the circumferential side wall of the base tube.

[0015] Furthermore, the irrigation device further comprises a reset assembly, and the reset assembly is configured to provide a driving force for resetting the friction disk.

[0016] Furthermore, the reset assembly includes a push rod and a sealing bolt, and the sealing bolt is threadedly inserted into the top of the nozzle; the push rod is configured to be able to be inserted into the top pipe from top to bottom from the top of the nozzle after the sealing bolt is removed, so as to drive the friction disk to move downward.

[0017] Furthermore, the first elastic member includes a tension spring.

[0018] Furthermore, the second elastic member includes a compression spring.

[0019] Furthermore, the nozzle is provided with a plurality of nozzles, and the plurality of nozzles are arranged along the circumferential direction.

[0020] The beneficial effects of the present invention are:

[0021] The water-saving high-pressure water spraying device provided by the present invention is used. When water is first introduced into the base pipe, as the water continues to flow in, the telescopic pipe gradually extends, and the first elastic member gradually accumulates force. During the extension of the telescopic pipe, the water drives the top pipe to extend outwards on the one hand, and at this time, under the action of the second elastic member, the middle pipe can synchronously follow the top pipe to extend outwards, so that mud cannot enter between the top pipe and the middle pipe, and on the other hand, the water flows out from the gap, so that mud cannot enter between the middle pipe and the bottom pipe. When the middle pipe extends outwards to the limit position, since its upward end is above the ground, the top pipe is in an environment without mud. Under the action of water, the top pipe can continue to rise, and mud cannot enter between the middle pipe and the bottom pipe. When the telescopic pipe is extended to the maximum length, water can be sprayed from the sprinkler head for irrigation. After the sprinkler irrigation is completed, the top pipe first falls back to the middle pipe stopper under the action of the first elastic member, and then falls back as a whole. At this time, water continues to flow out from the gap, so that mud can be prevented from entering between the bottom pipe and the middle pipe.

[0022] Furthermore, by setting up an annular filter, the water can be filtered during use to avoid clogging the nozzle and affecting the irrigation efficiency, and the water can be used to clear itself after the irrigation is completed to ensure the filtering performance.

[0023] Furthermore, when there are multiple irrigators and they share a water supply system, the irrigators are in different positions, so the blockage conditions of the annular filters therein may be different. The more severely blocked the annular filter is, the higher the height of the friction disk in the middle pipe is, so that the second elastic member stores less energy, and the middle pipe is pushed down smaller. When the water falls back, the middle pipe falls down in sequence according to the blockage conditions of the annular filters in the irrigators, and the middle pipe corresponding to the most severely blocked annular filter falls down first, so that the impurities at the annular filter can be flushed back into the water supply system in batches, thereby effectively avoiding the accumulation of impurities in the water supply system, and also giving priority to flushing out the impurities in the water, thereby avoiding affecting the water supply capacity of the water supply system and increasing the cleaning effect.

[0037] like Figures 1 to 7As shown, a water-saving high-pressure water spraying device provided by an embodiment of the present invention is used for irrigation, and is configured to include an irrigation device 1, the irrigation device 1 includes a base pipe 11, a telescopic pipe 12, a first elastic member and a second elastic member, the base pipe 11 is configured to receive water from the outside; the telescopic pipe 12 is vertically arranged on the circumferential side wall of the base pipe 11, and is connected to the base pipe 11, and can be telescopic along its own axial direction; the telescopic pipe 12 includes a top pipe 121, a middle pipe 122 and a bottom pipe 123 that are slidably sleeved from the inside to the outside in sequence, a gap for water discharge is formed between the bottom pipe 123 and the middle pipe 122, and a stop fit is formed between the bottom pipe 123 and the middle pipe 122, and a useful gap is formed between the bottom pipe 123 and the middle pipe 122 A nozzle 13 is provided on the top of the top pipe 121 in the gap for water outlet, and the nozzle 13 is configured to spray water for irrigation; the first elastic member is inserted into the top pipe 121 and connected between the top pipe 121 and the base pipe 11, and under the action of the first elastic member, the top pipe 121 has a tendency to move toward the direction close to the base pipe 11; the second elastic member is inserted into the middle pipe 122 and connected between the middle pipe 122 and the base pipe 11, and under the action of the second elastic member, the middle pipe 122 has a tendency to move away from the base pipe 11; when the top pipe 121 extends outward under the action of water, the middle pipe 122 can synchronously follow the top pipe 121 to extend outward under the push of the second elastic member, and when the middle pipe 122 extends outward to the extreme position, its upward end is above the ground.

[0038] Specifically in this embodiment, Figure 3 and Figure 4 As shown, the base pipe 11 is configured as a three-way tubular structure, and has a first branch pipe arranged upward and a second branch pipe arranged horizontally, and a water delivery hole is opened on the top of the second branch pipe, and the water delivery hole is connected to the first branch pipe; the bottom pipe 123 is configured to be fixedly inserted into the first branch pipe at the bottom end during installation, and the top end is suspended, the middle pipe 122 is configured to be slidably inserted into the bottom pipe 123 during installation, and the top pipe 121 is configured to be slidably inserted into the middle pipe 122 during installation.

[0039] like Figure 4 As shown, a first outer retaining ring 1211 is fixedly sleeved on the upper outer peripheral wall of the top pipe 121, and an inner retaining ring 1221 is fixedly inserted on the top inner peripheral wall of the middle pipe 122. The first outer retaining ring 1211 and the inner retaining ring 1221 stop to achieve the stop cooperation between the middle pipe 122 and the top pipe 121; a second outer retaining ring 1222 is fixedly sleeved on the upper outer peripheral wall of the middle pipe 122, as shown in FIG. Figure 6 As shown, a plurality of inner stoppers 1231 are fixedly arranged on the inner peripheral wall of the top of the bottom tube 123. The inner stoppers 1231 are arranged as a block structure with a fan-shaped cross section. The plurality of inner stoppers 1231 are arranged at equal intervals along the circumferential direction. The second outer stopper ring 1222 and the inner stoppers 1231 stop to achieve the stop cooperation between the middle tube 122 and the bottom tube 123. Figure 5 As shown, a plurality of outer stop blocks 1223 are fixedly arranged on the inner circumferential wall of the bottom of the middle tube 122. The outer stop blocks 1223 are arranged as a block structure with a fan-shaped cross-section. The plurality of outer stop blocks 1223 are arranged at equal intervals along the circumferential direction and are staggered with the inner stop blocks 1231 along the circumferential direction, so that a gap is formed between the bottom tube 123 and the middle tube 122.

[0040] like Figure 3 As shown, the nozzle 13 is configured as a cover-like structure, and the fixed cover is arranged on the top of the top pipe 121.

[0041] When in use, water is first introduced into the base pipe 11. As water continues to flow in, the telescopic pipe 12 gradually extends, and the first elastic member gradually accumulates force. During the extension of the telescopic pipe 12, the water drives the top pipe 121 to extend outwards. At this time, the downward pressure of the top pipe 121 on the middle pipe 122 disappears. Under the action of the second elastic member, the middle pipe 122 can synchronously follow the top pipe 121 to extend outwards, so that mud cannot enter between the top pipe 121 and the middle pipe 122. On the other hand, mud flows out from the gap, so that mud cannot enter between the middle pipe 122 and the bottom pipe 123. When the middle pipe 122 extends outwards to the limit position Since its upward end is above the ground, the top pipe 121 is in an environment without soil. Under the action of water, the top pipe 121 can continue to rise, and soil cannot enter between the middle pipe 122 and the bottom pipe 123; when the telescopic tube 12 is extended to the maximum length, water can be sprayed from the sprinkler 13 for irrigation; after the sprinkler irrigation is completed, under the action of the first elastic member, the top pipe 121 first falls back to the first outer retaining ring 1211 and the inner retaining ring 1221 to stop, and then falls back as a whole. At this time, water continues to flow out from the gap, thereby preventing soil from entering between the bottom pipe 123 and the middle pipe 122.

[0042] In some embodiments, the irrigator 1 is configured to further include an annular filter 17 , which is sleeved on the outside of the second elastic member and connected between the middle pipe 122 and the base pipe 11 , and is configured to receive water from the base pipe 11 .

[0043] Specifically in this embodiment, Figure 5 As shown, the annular filter screen 17 is configured as a cylindrical structure with both upper and lower ends open, and is configured to be flexible. The bottom end of the annular filter screen 17 is fixedly connected to the bottom of the first branch pipe and is communicated with the water delivery hole.

[0044] More specifically, in order to facilitate the installation of the top end of the annular filter 17, a mounting frame may be provided inside the middle tube 122, and the top end of the annular filter 17 is fixedly connected to the bottom end of the mounting frame.

[0045] During use, water is first passed into the second branch pipe, then enters the first branch pipe from the water delivery hole, and then enters the bottom pipe 123 after being filtered by the annular filter 17, thereby avoiding clogging the nozzle 13 and affecting the irrigation efficiency; after the irrigation is completed, as the water falls back, the water outside the annular filter 17 can backwash the annular filter 17, thereby ensuring the filtering performance of the annular filter 17.

[0046] In a further embodiment, in order to increase the irrigation area, a plurality of irrigation devices 1 are provided.

[0047] Specifically in this embodiment, Figure 1 As shown, the number of irrigators 1 can be six and they are evenly divided into two groups. The two groups are arranged in parallel and arranged together to form a rectangular shape. The three irrigators 1 in the same group are arranged at equal intervals.

[0048] In a further embodiment, the water-saving high-pressure water spraying equipment is configured to further include a water supply system 2 , and the water supply system 2 is configured to supply water to all the irrigation devices 1 simultaneously.

[0049] Specifically in this embodiment, the water supply system 2 is configured to include a water tank, a water pump and a pipe network structure, such as Figure 1 As shown, the pipe network structure is configured to include a water inlet pipe 21, a first water branch pipe 22 and two second water branch pipes 23, wherein the water inlet pipe 21 is vertically arranged, the first water branch pipe 22 and the second water branch pipe 23 are both horizontally arranged, and the water inlet pipe 21 and the first water branch pipe 22 together form a T-shaped structure, and the first water branch pipe 22 and the second water branch pipe together form a П-shaped structure; a switch valve is provided at one end of each second water branch pipe 23 away from the first water branch pipe 22, and the switch valve is in a closed state during irrigation and in an open state after the irrigation is completed; the pumping end of the water pump is connected to the water tank, and the drainage end of the water pump is connected to the water inlet pipe 21.

[0050] More specifically, the two groups of irrigation devices 1 are respectively disposed corresponding to the two second water distribution pipes 23 .

[0051] More specifically, Figure 2 As shown, the irrigator 1 is configured such that the second branch pipe is fixedly sleeved on the outside of the second water branch pipe 23 during installation.

[0052] When in use, the water pump is started, and the water in the water tank is first pumped out by the water pump, and then enters the irrigation device 1 through the water inlet pipe 21, the first water distribution pipe 22 and the second water distribution pipe 23 in sequence.

[0053] In a further embodiment, the irrigator 1 is configured to also include a friction disk 18, which is coaxially inserted into the middle tube 122 and is in friction contact with the middle tube 122; the top end of the annular filter 17 is arranged at the bottom of the friction disk 18, and the bottom end is arranged on the circumferential side wall of the base tube 11.

[0054] Specifically in this embodiment, Figure 5 As shown, a water hole is provided on the outer end surface of the friction disc 18 located on the annular filter screen 17, and the water hole facilitates the passage of water.

[0055] When in use, water is first passed into the second branch pipe, then into the first branch pipe from the water delivery hole, and then into the bottom pipe 123 after being filtered by the annular filter 17. On the one hand, the water drives the top pipe 121 to extend outward, and at this time, the downward pressure of the top pipe 121 on the middle pipe 122 disappears. Under the push of the second elastic member, the friction disk 18 drives the middle pipe 122 to extend outward synchronously with the top pipe 121 through friction, so that soil cannot enter between the top pipe 121 and the middle pipe 122. On the other hand, it flows out from the gap, so that soil cannot enter between the middle pipe 122 and the bottom pipe 123. When the middle pipe 122 extends outward to the extreme position, because its upward end is above the ground, the top pipe 121 is in an environment without soil. Under the action of water, the top pipe 121 can continue to rise, and soil cannot enter between the middle pipe 122 and the bottom pipe 123. When the telescopic pipe 12 is extended to the maximum length, water can be sprayed out from the sprinkler 13 for irrigation.

[0056] As water continues to flow in, the filter holes on the annular filter 17 are gradually blocked. Since the irrigator 1 is in different positions, the blockage conditions of the annular filter 17 therein may be different. The blockage allows the annular filter 17 to drive the friction disk 18 to move upward relative to the middle pipe 122 under the action of water pressure. The more severely blocked the annular filter 17 is, the higher the height of the friction disk 18 in the irrigator 1 corresponding to the middle pipe 122 is, so that the energy storage of the second elastic member is less, and the upward thrust on the middle pipe 122 is smaller; when the water falls back, the middle pipe 122 falls in sequence according to the blockage conditions of the annular filter 17 in the irrigator 1, among which the middle pipe 122 corresponding to the annular filter 17 with the most severe blockage falls first, so that the impurities at the annular filter 17 can be flushed back into the water supply system 2 in batches, thereby effectively preventing the accumulation of impurities in the water supply system 2 and avoiding affecting the water supply capacity of the water supply system 2.

[0057] In a further embodiment, the irrigation device 1 is configured to further include a reset assembly, which is configured to provide a driving force for resetting the friction disc 18 .

[0058] Specifically in this embodiment, the reset assembly is configured to include a push rod and a sealing bolt 14, and the sealing bolt 14 is threadedly inserted into the top of the nozzle 13; the push rod is configured to be able to be inserted into the top pipe 121 from top to bottom from the top of the nozzle 13 after the sealing bolt 14 is removed, so as to drive the friction disk 18 to move downward.

[0059] During use, regular inspections can be performed to ensure normal maintenance of the irrigation device 1 and the friction disc 18 can be reset in time through the push rod to avoid affecting the normal use of the irrigation device 1.

[0060] In some other embodiments, the first elastic member is configured to include a tension spring 15 .

[0061] Specifically in this embodiment, Figure 7 As shown, the top end of the tension spring 15 is fixedly connected to the bottom of the nozzle 13 and passes through the water hole, and the bottom end of the tension spring 15 is fixedly connected to the bottom of the first branch pipe. Under the action of the tension spring 15, the top pipe 121 has a tendency to move toward the direction close to the base pipe 11.

[0062] In a further embodiment, in order to improve the force uniformity of the top pipe 121, a plurality of tension springs 15 may be provided.

[0063] Specifically in this embodiment, the number of the tension springs 15 can be three and evenly arranged along the circumferential direction; correspondingly, three water holes are opened on the friction plate 18 .

[0064] In other embodiments, the second elastic member is configured to include a compression spring 16 .

[0065] Specifically in this embodiment, Figure 5 As shown, the top end of the compression spring 16 is fixedly connected to the bottom of the friction plate 18 , and the bottom end of the compression spring 16 is fixedly connected to the bottom of the first branch pipe. Under the action of the compression spring 16 , the middle pipe 122 has a tendency to move away from the base pipe 11 .

[0066] In other embodiments, in order to improve the uniformity of the water spraying of the nozzle 13, a plurality of nozzles are provided on the nozzle 13, and the plurality of nozzles are arranged along the circumferential direction.

[0067] When in use, water can be sprayed out from all the nozzles at the same time, and an umbrella-shaped water spraying area is formed, thereby improving the uniformity of the water spraying of the nozzle 13.

[0068] In other embodiments, in order to avoid affecting the normal use of the second elastic member, such as Figure 5 As shown, a sieve ring 19 is inserted at the water delivery hole. The sieve ring 19 is configured to have a plurality of sieve holes, and the size of the sieve holes is larger than the size of the filter holes on the annular filter screen 17 .

[0069] When in use, water can first be filtered through the sieve ring 19 to remove larger impurities, and then through the annular filter 17 to filter out smaller impurities. Through two levels of filtration, larger impurities are prevented from entering the bottom pipe 123 and affecting the normal use of the second elastic member.

[0070] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
