The movable platform includes an aircraft, a robot, an autopilot, and the like, and a detection device including a radar, a ranging sensor, and the like is mounted on the movable platform.
Referring to fig. 1, the movable platform (e.g., unmanned aerial vehicle) of the present invention can be applied to the fields of industry and agriculture, etc., to realize automatic control of fluid (gas or liquid) in a pipeline. For example, spraying of pesticides, etc. may be performed. The mobile platform comprises a fuselage 1, wings 2 connected to the fuselage 1 and a spraying system. The spraying system includes a tank 3, a water pump (not shown) connected to the tank 3, a flow divider (not shown), a flow meter (not shown) and solenoid valve assembly 4, and a spray head 5 connected to the solenoid valve assembly 4. The movable platform comprises an aircraft or the like. Fluid in the tank 3 flows from the water pump through the solenoid valve assembly 4 and is ejected from the nozzle 5. The spray head sprays the atomized fluid so as to be favorable for uniform spraying.
Referring to fig. 2 and 3, the solenoid valve assembly 4 includes a solenoid valve 41, a communication pipe sealing assembly fixed to the solenoid valve 41, and a connector 46 connected to the connection line 45. The communication pipe sealing assembly includes a communication pipe 42 and a packing 43. The seal 43 is located between the solenoid valve 41 and the communication pipe 42. According to an embodiment of the invention, the seal 43 is made of a material having elasticity. According to another embodiment of the invention, the seal 43 is a diaphragm. The connector 46 is connected to a power source (not shown) to supply power to the solenoid valve 41. The communication pipe 42 may be a two-way pipe or a multi-way pipe. In the illustrated embodiment, the communication pipe 42 is a three-way pipe, and the communication pipe 42 may be a four-way pipe, a five-way pipe, a six-way pipe, or the like, and the present invention is not limited to the number of passages of the communication pipe 42 and may be provided according to actual needs. According to an embodiment of the present invention, the nozzle 5 is connected to the communication pipe 42, and the fluid is sprayed out of the nozzle 5 after passing through the diverter, the flowmeter, the water pump, and the communication pipe 42 of the solenoid valve assembly 4 in this order. One of the spray heads 5 may be connected to each of the channels to facilitate the spraying of the fluid.
Referring to fig. 3 and 4, the communication pipe 42 includes a connection part 420, a first extension part 421, a second extension part 422, and a third extension part 423 extending from the connection part 420. The communication pipe 42 is provided with a first passage 4210 penetrating the first extension 421, a second passage 4220 penetrating the second extension 422, a third passage 4230 penetrating the third extension 423, an inlet 4211 located at one end of the first passage 4210, a first outlet 4221 located at one end of the second passage 4220, and a second outlet 4231 located at one end of the third passage 4230. The connection part 420 includes a first annular protrusion 4201, a partition 4202 having two ends connected to the first protrusion 4201, and a second annular protrusion 4203. The second projection 4203 surrounds the first projection 4201. The connection portion 420 includes a flat plate-shaped abutment portion 4204. The abutting portions 4204 are provided at four corners thereof with first assembly holes 4205, respectively. The positions and the number of the first assembling holes 4205 are not limited, and may be set according to actual requirements.
The seal 43 includes a base 430, a side wall 431 extending from the base 430, and a first stop 4310 extending from the side wall 431. As shown in fig. 9 to 10, the base 430 and the side wall 431 define a space 4301. When the sealing member 43 is in the open state, the space 4301 is in communication with the first passage 4210, the second passage 4220, and the third passage 4230, and fluid may enter the first passage 4210 through the inlet 4211, enter the second passage 4220, and enter the third passage 4230, and finally flow out through the first outlet 4221 and the second outlet 4231. The side wall 431 is sealed against the second protruding portion 4203, so as to prevent fluid from flowing out through a gap between the communicating tube 42 and the side wall 431.
As shown in fig. 11 to 12, when the sealing member 43 is in a sealed state, the base 430 is sealed against the communication pipe 42 to seal the first passage 4210 and the second passage 4220, and the first passage 4210, the second passage 4220 and the third passage 4230 are disconnected from each other. According to an embodiment of the invention, the base 430 of the seal 43 is sealed only with the first and second passages 4210, 4220. Specifically, in the illustrated embodiment, the base 430 is sealed against the first protrusion 4201 and the partition 4202, so that fluid cannot enter the second passage 4220 or the third passage 4230 through the first passage 4210, thereby completing the closing function of the communication pipe 42. Since the base 43 of the seal 43 seals with the second passage 4220, the second passage 4220 is also disconnected from the third passage 4230. When the movable platform is tilted, the fluid in the second channel 4220 or the third channel 4230 does not flow out through the first outlet 4221 or the second outlet 4231, so as to prevent dripping when spraying is not needed.
In the illustrated embodiment, the communication tube 42 is a three-way tube. When the communication pipe 42 includes more passages provided with outlets, for example, a fourth passage, a fifth passage, and so on are also provided. The seal 43 is required to ensure that each of the two channels is disconnected from each other to prevent dripping from the outlet.
Referring to fig. 3 and 5 to 9, the solenoid valve 41 includes a yoke assembly 411 and a case 410 covered to the yoke assembly 411. In one embodiment of the invention, the housing 410 is an encapsulated body. The yoke assembly 411 includes a coil bobbin 4110, a coil 4111 wound around the coil bobbin 4110, a yoke member 4112 surrounding the coil bobbin 4110, a rotor housing 4113 and a stator 4114 assembled to the yoke member 4112, a rotor 4115 assembled to the rotor housing 4113, and an elastic member 4116 (e.g., a return spring) abutting against the rotor 4115. The coil 4111 is connected to the connection line 45. When the coil 4111 is energized, a magnetic force is generated to drive the mover 4115 to move, so that the sealing member 43 is in an open state, and the base 430 of the sealing member 43 is disengaged from the communication pipe 42. According to an embodiment of the invention, the seal 43 is made of a material having elasticity. According to another embodiment of the invention, the seal 43 is a diaphragm. In one embodiment, the coil 4111 generates a magnetic force when energized to drive the mover 4115 to move. Due to the movement of the mover 4115, the sealing member 43 having elasticity is restored to its own shape, thereby opening the passage sealed by the sealing member 43.
After the coil 4111 is de-energized, the mover 4115 moves under the elastic force of the elastic member 4116 (i.e., the return spring), so that the mover 4115 abuts against the base 430 of the sealing member 43, and the sealing member 43 is in a sealed state, and at this time, the base 430 is sealed against the communication tube 42. That is, the seal 43 is elastically deformed so that the seal 43 is in a sealed state. The coil 4111 may be an enamel wire.
When the sealing member 43 is in an open state, the mover 4115 compresses the elastic member 4116. When the coil 4111 is energized, the elastic force of the elastic member 4116 that is pushed up against the mover 4115 is smaller than the electromagnetic attraction force between the stator 4114 and the mover 4115. Accordingly, the mover 4115 moves in a direction away from the seal member 42, so that the seal member 43 is in an open state.
The yoke member 4112 includes an upper yoke 41120 and a lower yoke 41121 fixed together, and the upper yoke 41120 and the lower yoke 41121 are formed by bending sheet metal and are enclosed into a ring shape to be sleeved on the coil bobbin 4110. The upper yoke 41120 includes a top wall 41122 and a first side wall 41123 extending from the top wall 41122. The lower yoke 41121 includes a bottom wall 41124 and a second side wall 41125 extending from the bottom wall 41124. The first side wall 41123 and the second side wall 41125 are welded and fixed. The upper yoke 41120 includes an upper through hole 41126 penetrating the top wall 41122. The coil bobbin 4110 has a generally "i" -shaped cross-section and is hollow in shape and includes a receiving portion 41101. The rotor housing 4113 passes through the upper through hole 41126 and is received in the receiving portion 41101. The lower yoke 41121 includes a lower penetration hole 41127. The stator 4114 passes through the lower through hole 41127 and is received in the receiving portion 41101. The rotor housing 4113 is interference fit with the upper yoke 41120, and the stator 4114 is interference fit with the coil bobbin 4110.
In the illustrated embodiment, the housing 410 and the yoke assembly 411 are integrally formed by injection molding to realize the waterproof function of the solenoid valve 41; and the casing 410 is covered on the connecting wire 45, so that the connection position between the connecting wire 45 and the casing 410 can be waterproof. The housing 410 includes a hole 4101, a recess 4102, a second stop 4104, and a plurality of second assembly holes 4103. The hole 4101 is provided for the mover 4115 to pass through to abut the seal 43. The solenoid valve assembly 4 includes a locking member 47, and the locking member 47 is assembled to a first assembly hole 4205 of the communication pipe 42 and a second assembly hole 4103 of the housing 410 to fix the communication pipe 42 to the housing 410. The seal 43 is received in the recess 4102. The first stop portion 4310 of the seal 43 cooperates with the second stop portion 4104 of the housing 410 to prevent the seal 43 from moving relative to the housing 410, so as to effectively ensure the sealing effect of the seal 43.
As shown in fig. 8 and 9, the base 430 of the sealing member 43 is bonded to the casing 410 to prevent the fluid in the communication pipe 42 from entering the solenoid valve 41, and prevent the fluid from corroding the solenoid valve 41, so that the service life of the solenoid valve 41 is effectively prolonged; secondly, the electromagnetic valve 41 does not need to use corrosion-resistant materials, so that the cost is saved; and meanwhile, according to an embodiment of the invention, the magnetic resistance in the magnetic conduction loop of the electromagnetic valve 41 is not increased because the electromagnetic valve 41 omits the waterproof magnetic isolation sleeve, so that the electromagnetic valve 41 has better magnetic conduction effect, and the requirements of miniaturization, light weight and low power consumption under the same electromagnetic attraction force of the electromagnetic valve 41 are met.
