Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a self-moving spraying equipment. Background Art

[0002] At present, with the development of agricultural modernization in my country, greenhouse crops have occupied more than 50% of the country's vegetable planting area. In order to improve production efficiency and reduce water consumption, greenhouse planting generally adopts sprinkler irrigation. However, there are some problems with the traditional sprinkler system: traditional greenhouse sprinkler irrigation mostly uses buried sprinklers, which requires the laying of a large number of underground pipes. This not only increases the initial investment cost, but also may damage the original sprinkler pipes during the later land reuse or replanning; another common sprinkler irrigation method is to use suspended sprinklers. Although this method reduces the impact on the land, it requires the layout of longer pipelines, resulting in poor aesthetics of the entire system, and may also increase the complexity and maintenance difficulty of the system. In addition, with the advancement of large-scale infrastructure construction in my country in recent years, a large amount of construction waste has been generated. These wastes will generate a lot of dust during the stacking process, which seriously affects the air quality of the surrounding environment. For construction waste receiving sites, since materials need to be stacked on the surface, it is impossible to set up buried sprinklers, and it is difficult to fully cover the area by only setting up sprinklers around, and it is impossible to effectively suppress the spread of dust. In view of the above problems, it is necessary to develop a new type of top-moving automatic spraying device to solve the problems existing in the traditional sprinkler irrigation system, and at the same time be suitable for the dust reduction needs of greenhouse cultivation and construction waste receiving sites.

[0036] Reference Figure 1 Fig.10 , a self-moving spraying device, comprising:

[0037] The gantry is provided with two mutually parallel mounting grooves 105, and the gantry is provided with a water inlet pipe 100;

[0038] The watering device comprises a telescopic assembly 120, an emptying assembly 180, a drain pipe 160, and an energy storage assembly. Two sets of telescopic assemblies 120 are respectively telescopically arranged in two mounting grooves 105. The water inlet pipe 100 is conductively connected with the telescopic assembly 120. The ends of the two telescopic assemblies 120 are conductively connected through the drain pipe 160. The emptying assembly 180 is arranged at the end of the telescopic assembly 120. One end of the energy storage assembly is fixed to the gantry, and the other end is transmission-connected to the drain pipe 160.

[0039] The trigger device includes a water discharge component 150 and a reset component 170. The water discharge component 150 is arranged at the end of the installation groove 105, and the reset component 170 is arranged at the head end of the installation groove 105. The water discharge component 150 and the reset component 170 are arranged corresponding to the emptying component 180.

[0040] When water flows through the telescopic component 120, it drives the drain pipe 160 to move in the direction of the water discharge component 150, and drives the energy storage component to extend and deform. When the telescopic component 120 moves to the end of the installation groove 105, the water discharge component 150 triggers the emptying component 180 to discharge the water in the telescopic component 120. Driven by the energy storage component, the drain pipe 160 returns to the head end of the installation groove 105, and makes the reset component 170 contact with the emptying component 180 to reset the emptying component 180.

[0041] Through the dynamic extension and contraction of the telescopic component 120, the spraying range can change with the movement of the telescopic component 120, so as to effectively utilize water resources and reduce water waste; the extension and contraction of the telescopic component 120 mainly rely on the water pressure and the elastic potential energy stored in the energy storage component, and no additional power source is required, so that energy consumption can be significantly reduced; when the telescopic component 120 reaches the end of the installation groove 105 and completes the spraying action, the energy storage component can automatically drive the drain pipe 160 to return to the initial position, realizing automatic resetting and simplifying the operation process; the extension and contraction of the telescopic component 120 can be adjusted as needed, so as to achieve spraying of different ranges and intensities, enhancing the flexibility and adaptability of the spraying equipment. Practicality; the design of the telescopic component 120 reduces the reliance on complex mechanical parts, reduces the failure rate, and thus reduces maintenance costs; the design of the mounting slot 105 on the gantry and the telescopic component 120 makes the entire device compact, easy to install and deploy, and particularly suitable for application scenarios with limited space; through a simple mechanical structure and an automated triggering mechanism, the stability of the device during long-term operation is ensured, and the reliability of the device is high; the movement and reset of the telescopic component 120 are completely controlled by water pressure and energy storage components, which is easy to operate and convenient for users to perform precise control; whether it is agricultural irrigation or dust reduction on construction sites, this top-moving automatic spraying device can provide an effective solution. The utility model provides an efficient, energy-saving, and automated top-moving automatic spraying device. Through its unique design of the telescopic component 120, the venting component 180, the drain pipe 160, and the energy storage component, it can greatly reduce energy consumption and maintenance costs while ensuring the spraying effect, and is a very practical and efficient spraying solution.

[0042] The sprinkler device further includes a solenoid valve 110, which is disposed between the water inlet pipe 100 and the water discharge pipe 160. The solenoid valve 110 controls the conduction or closing of the water discharge pipe 160 and the water inlet pipe 100. Through the arrangement of the solenoid valve 110, precise control of the spraying operation can be achieved to ensure that the irrigation or dust reduction work is carried out according to a predetermined schedule, thereby improving the automation level of the system. Through the partition control function of the solenoid valve 110, the spraying area can be flexibly adjusted according to actual needs.

[0043] When the venting assembly 180 abuts against the drain assembly 150, the solenoid valve 110 is in a closed state. The automatic closing of the solenoid valve 110 reduces unnecessary water flow, thereby reducing the energy consumption required to maintain the water flow, which helps to save energy and reduce emissions. It is understandable that the solenoid valve 110 can use a two-way solenoid valve or a two-position three-way solenoid valve. By matching different types of solenoid valves, one solenoid valve can control the water outlet states of multiple different partitions.

[0044] Reference Figure 2 and Figure 3 , the telescopic assembly 120 is installed by sleeve-jointing a plurality of pipes with increasing diameters, and a seal is provided at the joint of adjacent pipes. By sleeve-jointing a plurality of pipes with increasing diameters, a stable telescopic structure is formed, the stability and durability of the overall structure are enhanced, and the telescopic assembly 120 can adjust the telescopic length according to actual needs, realize the flexible adjustment of the spraying range, and improve the adaptability and flexibility of the system. In this embodiment, two water outlets are provided at the end of the telescopic assembly 120, one water outlet is used to install the emptying assembly 180, and the other water outlet is used to connect the drain pipe 160. It can be understood that the number of telescopic assemblies 120 can be adaptively improved according to the length of the installation groove 105. The preferred number of telescopic assemblies 120 is four, and four pipes with increasing diameters are sleeved with each other. When the telescopic assembly 120 is filled with water, the telescopic assembly 120 extends in the direction of the installation groove 105, driving the drain pipe 160 to move in the same direction, and causing the energy storage assembly to extend and deform.

[0045] The sprinkler device also includes a plurality of sprinkler heads 190, which are arranged at intervals along the direction in which the drain pipe 160 extends, and the sprinkler heads 190 are conductively connected to the drain pipe 160. By arranging a plurality of sprinkler heads 190 at intervals on the drain pipe 160, it can be ensured that water is distributed more evenly during irrigation or dust reduction operations, thereby improving the spraying effect. The independent installation of the sprinkler heads 190 facilitates individual replacement and maintenance, thereby reducing maintenance costs.

[0046] The venting assembly 180 includes a water blocking baffle 200 and a first spring 210. The water blocking baffle 200 is arranged at the end of the telescopic assembly 120. The first spring 210 is fixed at the end of the telescopic assembly 120 and connected to the water blocking baffle 200 so that the water blocking baffle 200 abuts against the water outlet at the end of the telescopic assembly 120. The first spring 210 ensures a good seal between the water blocking baffle 200 and the water outlet at the end of the telescopic assembly 120, reduces the possibility of water leakage, and enhances the reliability and stability of the system.

[0047] The venting assembly 180 also includes a baffle back card 270, a second spring 220 and a back card fixing member 260. The baffle back card 270 is fixedly connected to the water-blocking baffle 200. The baffle back card 270 is provided with a first wedge block 230. The back card fixing member 260 is arranged on the inner side wall of the telescopic assembly 120 through the second spring 220. The back card fixing member 260 is provided with a second wedge block 240. The first wedge block 230 and the second wedge block 240 are adapted to each other. When the reset assembly 170 squeezes the baffle back card 270, the first wedge block 230 and the second wedge block 240 are in a separated state, and the telescopic assembly 120 switches to the water storage working condition. When the water discharge assembly 150 squeezes the baffle back card 270, the first wedge block 230 is clamped on the second wedge block 240, and the telescopic assembly 120 switches to the water discharge working condition. Through the interaction of the baffle back card 270, the second spring 220 and the back card fixing member 260, the telescopic component 120 can automatically switch between the water storage condition and the water discharge condition, thereby improving the degree of automation of the system; the mutual adaptation design of the first wedge block 230 and the second wedge block 240 ensures the reliable opening and closing of the emptying component 180, and reduces system failures caused by mechanical failures; the linkage design of the baffle back card 270 and the water-blocking baffle 200 enables the telescopic component 120 to quickly switch the working condition according to different spraying requirements, thereby enhancing the flexibility of the system.

[0048] The second spring 220 is arranged perpendicular to the direction of movement of the baffle back card 270, and the reset assembly 170 is provided with a conical block 250. When the reset assembly 170 squeezes the baffle back card 270, the conical block 250 pushes the back card fixing member 260 to retract under the limit of the second spring 220, forming an exit channel for the baffle back card 270. The design of the conical block 250 ensures the stable retraction of the back card fixing member 260, thereby improving the stability and reliability of the system.

[0049] The energy storage assembly includes a plurality of driving steel bars 130 and a plurality of driving ropes 140, wherein the plurality of driving steel bars 130 are arranged at intervals on the gantry along a direction parallel to the drain pipe 160, and one end of the driving rope 140 is connected to the drain pipe 160, and the other end is connected to the driving steel bar 130. The arrangement of the plurality of driving steel bars 130 can effectively store elastic potential energy, and provide sufficient power for the retraction of the telescopic assembly 120. The design of the driving steel bars 130 and the driving rope 140 makes the energy storage assembly compact, occupies a small space, and is easy to install and maintain. It is understandable that the energy storage assembly can also be replaced by a spring, but in the present embodiment, the driving steel bar 130 is preferably used as the energy storage assembly.

[0050] The installation groove 105 is a cavity-type structure with one end open, and a liquid recovery groove is formed in the installation groove 105. The water discharged from the venting assembly 180 can be effectively collected, thereby avoiding the waste of water resources and helping to reduce long-term operating costs.

[0051] It can be understood that under the spraying condition, after the device is connected to the water source, the zone spraying is regulated through the solenoid valve 110. When the solenoid valve 110 corresponding to a certain zone is opened, the water flows through the water inlet pipe 100, the solenoid valve 110, the telescopic component 120, and the water is discharged through the sprinkler head 190 to complete the watering irrigation or precipitation and dust removal work. When the nozzle discharges water, the water pressure in the pipe will also push the drain pipe 160 and the sprinkler nozzle 190 to move forward. At this time, the telescopic component 120 is in an extended working condition, and the path along the movement of the nozzle will be covered by the water discharge of the sprinkler nozzle 190. When the telescopic component 120 is fully extended, the sprinkler nozzle 190 also reaches the farthest point, and the emptying component 180 at the front end of the telescopic component 120 will touch the drain component 150 of the mounting groove 105. Under the driving force of the water pressure, the front end of the water-blocking baffle 200 is restricted by the drain component 150 and cannot move, so that the water-blocking baffle 200 is separated from the water outlet of the telescopic component 120, and the baffle back card 270 is fastened with the back card fixing part 260. The hole covered by the emptying component 180 remains open. After detecting the water leakage in the pipeline, the solenoid valve 110 of the partition is immediately closed to stop the water supply, the extended working condition of the telescopic component 120 ends, and the elastic potential energy accumulated in the energy storage component reaches the maximum.

[0052] Under non-spraying conditions, after the solenoid valve 110 is closed and the venting assembly 180 is opened, the driving force for the entire system to move outward disappears. At this time, under the recovery of the elastic potential energy of the energy storage assembly, the entire device moves back at a certain speed and returns to the initial position. When the device returns to the initial position, the back card fixing part 260 abuts against the conical block 250 of the reset assembly 170. Since the size of the conical block 250 is relatively large, the conical block 250 will push the back card fixing part 260 to move outward. After moving to a certain distance, the baffle back card 270 will be separated from the back card fixing part 260. Under the action of the first spring 210 and the conical block 250, the water-blocking baffle 200 will be close to the hole again, and the entire device will return to the initial working state, waiting for the next spraying work.

[0053] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
