[0041] The application will be further described below in conjunction with the accompanying drawings and examples. It should be understood that the specific examples described herein are intended to be illustrative only and are not in any way limiting of the application. In addition, it should be understood that in the drawings, only the parts pertinent to the application are shown and not all of the parts of the device are shown.

[0042] In the description of the application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0043] In the present application, unless otherwise explicitly specified and limited, the "upper" or "lower" of the first feature to the second feature can include the direct contact of the first and second features, or the indirect contact of the first and second features through another feature between them. Moreover, the "upper", "upper" and "upper" of the first feature to the second feature includes the vertical and oblique above of the first feature to the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The "lower", "lower" and "lower" of the first feature to the second feature includes the vertical and oblique below of the first feature to the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0044] In the description of the present embodiment, the terms "upper", "lower", "right", etc. orientation or position relationship is based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the application. In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0045] The present application provides a multi-dimensional water jet spraying system applied to the field of water jet cutting. A tool that uses a water jet to cut objects. Unlike the principle of laser cutting equipment, water jet has no thermal stress, so there is no chemical change in the cutting process without high temperature, and the cut object will not be deformed. Therefore, the water jet cutting equipment can perform one-time cutting processing of any curve on any material (except water cutting, other cutting methods will be limited by the material variety); no heat and harmful substances are generated during cutting, the material has no thermal effect (cold cutting), and no secondary processing is required after cutting.

[0046] However, the water jet spraying system in the current water jet cutting device cannot be applied to complex positions and angles, and the water jet spraying system provided in the embodiment improves the technical problem.

[0047] Figure 1 is a structural schematic diagram of a first perspective of the multi-dimensional water jet system provided in the embodiment, Figure 2 is a structural schematic diagram of a second perspective of the multi-dimensional water jet system provided in the embodiment, as Figures 1-2 shown, the multi-dimensional water jet system comprises a first rotating mechanism 11, a first support 21, a second rotating mechanism 12, a second support 22, a third rotating mechanism 13, a third support 23, and a water jet nozzle 3.

[0048] The output end of the first rotating mechanism 11 rotates around the first axis L1, and the first support 21 is connected to the output end of the first rotating mechanism 11, that is, when the first rotating mechanism 11 is started, the first support 21 can rotate around the first axis L1.

[0049] In the embodiment, the output end of the first rotating mechanism 11 is provided with a transmission mechanism, and the first support 21 is connected to the first rotating mechanism 11 through the transmission mechanism and is driven by the first rotating mechanism 11. The transmission mechanism is not limited to a transmission rod or a transmission shaft.

[0050] In the embodiment, the output end of the first rotating mechanism 11 can rotate clockwise around the first axis L1 or counterclockwise around the first axis L1, and the rotation speed of the first rotating mechanism 11 can be adjusted, so that its speed can be fast or slow as needed.

[0051] In the embodiment, the first rotating mechanism 11 can be, but is not limited to, a spiral rotating mechanism, a cam rotating mechanism, a crank rotating mechanism, a hinge rotating mechanism, or a connecting rod rotating mechanism.

[0052] In the embodiment, in order to realize more accurate position accuracy and speed control of the first support 21, the first rotating mechanism 11 is selected as a servo motor.

[0053] It can be understood that the servo motor can control the speed and has very accurate position accuracy, can convert the voltage signal into torque and speed to drive the control object. The servo motor rotor speed is controlled by the input signal and can quickly respond, and is used as an execution element in an automatic control system, and has characteristics such as small electromechanical time constant and high linearity, and can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two major categories of direct current and alternating current servo motors, and the main feature is that when the signal voltage is zero, there is no self-rotation phenomenon, and the speed uniformly decreases with the increase of torque.

[0054] The first support 21 is not limited to a combined or integral piece, and is not limited to a support body made of metal such as stainless steel, copper-aluminum alloy, etc., and is not limited to a support body made of inorganic non-metallic material (ceramics, calcium carbonate, etc.), or high polymer (polyamide, polyester, polycarbonate, polyethylene, polypropylene, ABS, etc.). In this embodiment, the first support 21 is made of ABS, which has certain corrosion resistance and is more suitable for water jet spraying systems.

[0055] The fixed end of the second rotating mechanism 12 is connected to the first support 21, and the output end of the second rotating mechanism 12 rotates around the second axis L2. The first axis L1 and the second axis L2 are perpendicular to each other. When the system is in the state shown in FIGS. 1 and 2, the direction indicated by the first axis L1 is horizontal, and the direction indicated by the second axis L2 is vertical. Figure 1 and Figure 2 The direction indicated by the second axis L2 changes accordingly when the first rotating mechanism 11 moves and drives the second rotating mechanism 12 to move, but is always perpendicular to the first axis L1.

[0056] It should be noted that the output end of the second rotating mechanism 12 can rotate counterclockwise around the second axis L2, or clockwise around the second axis L2.

[0057] It should be noted that the output end of the second rotating mechanism 12 can rotate counterclockwise around the second axis L2, or clockwise around the second axis L2.

[0058] The fixed end of the second rotating mechanism 12 is connected to the first support 21, so when the first support 21 rotates around the first axis L1 under the action of the first rotating mechanism 11, the second rotating mechanism 12 rotates around the first axis L1 synchronously, and the output end of the second rotating mechanism 12 can rotate around the second axis L2 independently of the first support 21.

[0059] The second support 22 is connected to the output end of the second rotating mechanism 12, and can rotate around the first axis L1 together with the second rotating mechanism 12 and the first support 21, or can rotate around the second axis L2 independently under the action of the second rotating mechanism 12.

[0060] In this embodiment, the output end of the second rotating mechanism 12 is provided with a transmission mechanism, and the second support 22 is connected to the second rotating mechanism 12 through the transmission mechanism and is driven by the second rotating mechanism 12. The transmission mechanism is not limited to a transmission rod or a transmission shaft.

[0061] It should be noted that the rotation speed of the second rotating mechanism 12 can be adjusted, and can be fast or slow as needed. The second rotating mechanism 12 in this embodiment is also a servo motor. The second support 22 is made of ABS plastic.

[0062] The fixed end of the third rotating mechanism 13 is connected to the second support 22, and the output end of the third rotating mechanism 13 rotates around the third axis L3. In this embodiment, the third axis L3, the first axis L1 and the second axis L2 are perpendicular to each other. Figure 1 and Figure 2 As shown in the current state of the system, the first axis L1 is horizontal, the second axis L2 is vertical, and the third axis L3 is front-to-back.

[0063] The fixed end of the third support 23 is connected to the output end of the third rotating mechanism 13, so that the third support 23 can rotate around the first axis L1 when the first rotating mechanism 11 acts on it, rotate around the second axis L2 when the second rotating mechanism 12 acts on it, and rotate around the third axis L3 when the third rotating mechanism 13 acts on it.

[0064] In this embodiment, the output end of the third rotating mechanism 13 is provided with a transmission mechanism, and the third support 23 is connected to the third rotating mechanism 13 through the transmission mechanism and is driven by the third rotating mechanism 13. The transmission mechanism is not limited to a transmission rod or a transmission shaft.

[0065] The water jet nozzle 3 is connected to the third support 23, so that it can move in multiple dimensions under the action of the first rotating mechanism 11, the second rotating mechanism 12 and the third rotating mechanism 13.

[0066] For example, when only the first rotating mechanism 11 is activated, the first support 21 rotates around the first axis L1, at this time, the second rotating mechanism 12 on the first support 21 rotates around the first axis L1 synchronously, and the second rotating mechanism 12 is connected to the second support 22, the third rotating mechanism 13 is connected to the second support 22, the third support 23 is connected to the third rotating mechanism 13, and the water jet nozzle 3 is connected to the third support 23, at this time, the water jet nozzle 3 rotates around the first axis L1.

[0067] When only the second rotating mechanism 12 is activated, the second support 22 rotates around the second axis L2, at this time, the third rotating mechanism 13 on the second support 22, the third support 23 connected to the third rotating mechanism 13 and the water jet nozzle 3 at the upper end of the third support 23 rotate around the second axis L2.

[0068] In addition, the first rotating mechanism 11, the second rotating mechanism 12 and the third rotating mechanism 13 can also be activated simultaneously by any two or three at the same time, at this time, the activity range of the water jet nozzle 3 is larger, but still based on the first axis L1, the second axis L2 and the third axis L3.

[0069] In order to reduce the volume occupied by the multi-dimensional water jet spraying system, the first support 11 is provided with a groove 110, and the transmission shaft 120 between the rotating mechanism 12 and the second support 22 is arranged in the groove 110, and the transmission shaft 120 extends along the second axis L2. It can be understood that the groove 110 of the first support 11 accommodates the transmission shaft 120, so that the second support 22 occupies a more compact area.

[0070] The generated sewage after polishing generally falls into the water tank arranged on the environment or the ground with the water flow, and a large amount of used abrasive and cut material debris are contained in the sewage, which also causes waste of effective substances, especially waste of water.

[0071] Figure 3 is a structural schematic diagram of a multi-dimensional water jet spraying system provided by another preferred embodiment of the present application, which is combined with Figures 1-3 As shown in the figure, the multi-dimensional water jet spraying system further comprises a sewage collecting device 4 and a sewage treatment device 5. The sewage collecting device 4 is opposite to the water jet nozzle 3 along the water flow ejection direction, and is used to collect and reduce the flow rate of the water jet. The sewage treatment device 5 is connected with the sewage collecting device 4, and the sewage treatment device 5 is used to absorb and purify the sewage collected from the sewage collecting device 4.

[0072] The sewage collecting device 4 and the water jet nozzle 3 are opposite, and the water jet ejected from the water jet nozzle 3 contains particulate matter after completing the cutting work, and the water jet continues to be sprayed to the sewage collecting device 4, at which time the sewage collecting device 4 collects the part of the water jet and can reduce the flow rate of the water jet in order to carry out sewage treatment in the sewage treatment device 5 subsequently.

[0073] It should be noted that the sewage treatment device 5 can return the purified water to the water jet nozzle 3 after treating the sewage, so as to repeatedly apply the water and save water resources.

[0074] In the embodiment, the third support 23 extends along the arc direction, and the water jet nozzle 3 and the sewage collecting device 4 are respectively arranged at two ends of the third support 23.

[0075] Since the third support 23 extends along the arc, and the water jet nozzle 3 and the sewage collecting device 4 are respectively located at two ends of the third support 23, the water jet will not splash or only a small amount of splash on the third support 23 after cutting is completed. Since the speed of the water jet is very high at this time, if it directly splashes on the third support 23, it will be easy to cause damage to the third support 23.

[0076] In the embodiment, the third support 23 is provided as a 180° arc structure.

[0077] Optionally, the third support 23 is provided with a plurality of connecting holes along the length direction thereof, the connecting holes are arc-shaped, and the water jet nozzle 3 and the sewage collecting device 4 are selectively arranged in different connecting holes. Since the third support 23 is arc-shaped, the distance between the water jet nozzle 3 and the sewage collecting device 4 is different when they are arranged in different connecting holes, thereby adjusting the distance between them.

[0078] In the embodiment, the water jet nozzle 3 and the sewage collecting device 4 are both provided with threaded holes, the inner side of the third support 23 is connected to the threaded holes by penetrating the connecting holes with one end of a bolt and connecting the other end of the bolt to the outer side surface of the third support 23, thereby fixing the water jet nozzle 3 and the sewage collecting device 4.

[0079] It should be noted that the threaded holes on the water jet nozzle 3 and the sewage collecting device 4 can be provided with a plurality of threaded holes, thereby improving the connection stability of the water jet nozzle 3 and the sewage collecting device 4 with the third support 23.

[0080] Figure 4 is a sectional view of the sewage treatment device in the embodiment of the present application, Figure 5 is Figure 4 is a side view of the sewage treatment device shown in the figure, as shown in Figures 4-5 The sewage collecting device 4 includes a collector body 40, and the collector body 40 is provided with an inner cavity, and the water jet entering the inner cavity will be slowed down and then sucked by the negative pressure generated by the sewage treatment device 5.

[0081] In the embodiment, the collector body 40 is in a circular tube structure, and the inner cavity thereof is a cylinder. The collector body 40 and the third support 23 are connected to each other, and the connection between the collector body 40 and the third support 23 is released to disconnect the sewage collecting device 4 from the third support 23.

[0082] The end of the collector body 40 facing the water jet nozzle 3 is provided with a collecting portion 41, and the water jet jetted to the collecting portion 41 will be guided into the inner cavity by the collecting portion 41.

[0083] Specifically, the collecting portion 41 includes an arc surface structure 411, the central axis of the arc surface structure 411 is coaxial with the jetting direction of the water jet, the arc surface 411 is provided with a water inlet hole 4110 at the center thereof, in other words, the connecting line of the water inlet hole 4110 and the nozzle port of the water jet nozzle 3 is coaxial with the jetting direction of the water jet.

[0084] In the embodiment, the arc surface structure 411 is in a spherical surface structure, and the water inlet hole 4110 is a circular hole. After the water jet cutting operation is completed, the water jet generally presents a splashing state, the arc surface structure 411 is more likely to receive more water, and the number of times of rebounding of the water after hitting the arc surface structure 411 is minimized, and the water then enters the water inlet hole 4110.

[0085] The collecting part 41 further comprises a baffle 412 which is circumferentially arranged along the arc structure 411 towards the edge of the water jet nozzle 3. In this embodiment, the baffle 412 has a circular edge at both ends, so that the baffle 412 has a sectional conical structure. The inner diameter of the end of the baffle 412 towards the water jet nozzle 3 is greater than the radius of the other end, so that more water flow can be introduced.

[0086] In this embodiment, the collecting part 41 has an integrated structure, i.e. the baffle 412 and the arc structure 411 are fixedly connected. It can be understood that the collecting part 41 can also be provided as a split structure, so that the baffle 412 and the arc structure 411 can be disassembled or assembled.

[0087] Further, the arc structure 411 is provided with a water inlet hole 4110, one end of which is arranged in the inner cavity, and the other end of the baffle 412 away from the arc structure 411 is arranged outside the inner cavity. In this embodiment, the baffle 412 is completely arranged outside the collector body 40, and the arc structure 411 is completely arranged inside the collector body 40.

[0088] In this embodiment, due to the extremely fast speed of the water jet, in order to effectively prolong the service life of the sewage collecting device 4, the collecting part 41 can be optionally provided as a structure with greater hardness, for example, the collecting part 41 is made of tungsten steel material.

[0089] The inner cavity of the sewage collecting device 4 is filled with a plurality of speed reduction blocks 42, and the speed reduction blocks 42 in contact with each other form gaps through which water flow can pass. After the water flow passes through the water inlet hole 4110, it will be hindered by the speed reduction blocks 42, thereby achieving speed reduction, and the gaps formed between the speed reduction blocks 42 in contact with each other can allow water flow to pass through, and the gaps and the gaps communicate to form a channel for water flow, so that the water flow is not blocked and accumulated in the inner cavity.

[0090] In this embodiment, the speed reduction blocks 42 are selected to have a spherical structure, and the spherical bodies are in point contact with each other, and the contact between a plurality of adjacent spherical bodies also does not form a blocking surface. Moreover, the particles generated after the cutting material is mixed in the water flow are easy to cause wear to the speed reduction blocks 42, and the use of spherical bodies can reduce the contact surface and contact time between the particles and the speed reduction blocks 42.

[0091] It should be noted that, in order to prevent the water flow from wearing the speed reduction blocks 42, the speed reduction blocks 42 can be made of a material with greater hardness, and in this embodiment, the speed reduction blocks 42 are also made of tungsten steel. Of course, the diameter of the spherical bodies can be adaptively selected according to the size of the inner cavity, and at the same time, the diameter of the spherical bodies is not limited to a uniform size, but can also be provided in multiple diameters, so that the gaps formed are large and small.

[0092] The speed reduction block 42 is the main factor of speed reduction, and should be able to be replaced after wearing out, so the collector body 40 can be provided with a replacement window, and opening the replacement window can replace the speed reduction block 42 in the inner cavity. In this embodiment, the collection part 41 and the collector body 40 are threadedly connected, so that the end of the collector body 40 connected to the collection part 41 serves as a window for replacing the speed reduction block 42.

[0093] It should be noted that the arc surface structure 411 and the collector body 40 can be threadedly connected or interference sealed and connected. In this embodiment, the edge of the arc surface structure 411 is provided with external threads, and the inner wall of the collector body 40 is provided with internal threads, and the two are threadedly and sealingly connected.

[0094] The end of the collector body 40 away from the water jet nozzle 3 is provided with a water outlet hole 400, and the sewage treatment device 5 is connected to the water outlet hole 400 and generates a negative pressure capable of sucking water flow. That is, the sewage treatment device 5 generates a negative pressure, and the negative pressure airflow will make the water flow of the collection part enter the water inlet hole 4110, and then pass through the inner cavity of the collector body 40, be slowed down by the speed reduction block 42, and finally enter the sewage treatment device 5 from the water outlet hole 400.

[0095] In this embodiment, the number of water outlet holes 400 is three, which improves the water outlet efficiency. Of course, the number of water outlet holes 400 in this embodiment is not limited, and can be adapted according to the diameter of the collector body 40.

[0096] It can be understood that the diameter of a single water outlet hole 400 is smaller than the speed reduction block 42, so that the negative pressure airflow will not suck the speed reduction block 42 into the sewage treatment device 5. In this embodiment, the diameter of the water outlet hole 400 is one third of the diameter of the smallest size speed reduction block 42.

[0097] Figure 6 is a structural schematic view of the sewage treatment device in this embodiment, as Figure 6 shown, the sewage treatment device 5 includes a sand-water separator 51 and a filter box 52, one end of the sand-water separator 51 is connected to the sewage collection device 4 for coarse filtration to make sand and stones settle and be discharged, and the filter box 52 is connected to the other end of the sand-water separator 51 to absorb the water on the upper layer of the sand-water separator 51 and filter.

[0098] The sewage treatment device 5 is coarsely filtered by the sand-water separator 51, and then finely filtered by the filter box 52, so that the sewage treatment device 5 realizes secondary filtration and reduces the content of particulate matter in the final effluent.

[0099] The sand-water separator 51 is arranged along or at an angle to the vertical direction. In this embodiment, the sand-water separator 51 is arranged at an angle of about 45° to the horizontal plane. When the water flows into the sand-water separator 51, the particles and water are stratified, and the particles are naturally settled at the bottom of the sand-water separator 51 due to gravity. It can be understood that the closer to the bottom of the sand-water separator 51, the more particles, and the clearer the water in the upper layer of the sand-water separator 51.

[0100] The bottom of the sand-water separator 51 is provided with a sand and stone discharge valve 511. Opening the sand and stone discharge valve 511 can discharge the particles in the sand-water separator 51.

[0101] In this embodiment, the sand-water separator 51 is a cyclone separator. The water is cyclone filtered in the separator, and the particles are separated and removed by different centrifugal forces, so as to obtain filtered water. For the sand-water separator 51 provided in this embodiment, the water enters the cyclone filter from the upper part tangentially downward, and comes out from the water outlet at the upper part. A filter screen is installed below the water outlet at the upper part, and the impurities before the water outlet are finally filtered through the filter screen, so as to ensure that the obtained water meets the design requirements.

[0102] In this embodiment, the filter box 52 is internally provided with a multi-layer filter screen structure. The water flowing out of the sand-water separator 51 enters the filter box 52 from the filter box 51. The multi-layer filter screen structure is arranged from top to bottom in sequence, and the pore size of the filter screen gradually decreases from top to bottom.

[0103] It should be noted that the filter box 52 is provided with a filtered water outlet. The filtered water outlet is connected to the water storage tank or directly connected to the water inlet end of the water jet nozzle 3.

[0104] The sewage treatment device 5 further comprises a water pump 53 for providing power. The pressure generated by the water pump 53 can suck the sewage in the collector body 40 into the sand-water separator 51, and can also suck the water in the upper layer of the sand-water separator 51 into the filter box 52.

[0105] The working principle of the multi-dimensional water jet spraying system provided in this embodiment is as follows:

[0106] The first rotating mechanism 11 drives the first support 21 to rotate around the first axis L1, so that the second rotating mechanism 12 on the first support 21 can rotate around the first axis L1, and the second rotating mechanism 12 is connected with the second support 22, the third rotating mechanism 13 is arranged on the second support 22, the third rotating mechanism 13 is connected with the third support 23, the water jet nozzle 3 is arranged on the third support 23, and then the water jet nozzle 3 rotates around the first axis L1, the second rotating mechanism 12 drives the second support 22 to rotate around the second axis L2, and then the water jet nozzle 3 rotates around the second axis L2, the third rotating mechanism 13 drives the third support 23 to rotate around the third axis L3, and then the water jet nozzle 3 rotates around the third axis L3, so that the water jet nozzle 3 can realize multi-dimensional movement, thereby being capable of polishing the workpiece at various positions and angles. After the water jet cutting operation is completed, the water flow is generally in a sputtering state, the arc surface structure 411 and the baffle 412 guide the sputtered water flow from the water inlet hole 4110 to the middle. The inner cavity of the sewage collecting device 4 is filled with a plurality of speed reduction blocks 42, and the speed reduction blocks 42 in contact with each other form a gap through which the water flow passes. After the water flow passes through the water inlet hole 4110, the water flow is hindered by the speed reduction blocks 42, so that the speed of the water flow is reduced, and the gap formed between the speed reduction blocks 42 in contact with each other allows the water flow to pass through, and the gap and the gap communicate to form a channel for the water flow to flow, so that the water flow is not blocked and accumulated in the inner cavity. The sewage treatment device 5 is coarsely filtered through the sand-water separator 51, and then finely filtered through the filter box 52, so that the sewage treatment device 5 realizes secondary filtration and reduces the content of particulate matter in the final effluent.
