Description

Technical Field

[0001] The utility model relates to an electric control valve, and more specifically, to an intelligent water path distributor. Background Art

[0002] With the continuous progress of technology, cameras are increasingly used. Whether it is driverless vehicles, road traffic monitoring, or the visual perception of industrial robots, cameras are used as detection heads. Keeping these detection heads clear at all times is also the key to ensuring the normal operation of the equipment. Therefore, it is necessary to clean the detection heads regularly. However, since the detection heads to be cleaned are installed in different positions, multiple water paths need to be designed, and the water path distribution is achieved through a water path distributor. Multiple spray nozzles are provided on the water path distributor, and the opening and closing of the water path are realized through the on-off of the spray nozzles. However, the opening of the spray nozzles of the initial design of the water distributor needs to be carried out in sequence, and only one spray nozzle can be opened at a time, resulting in the problem of low water outlet efficiency. Summary of the Utility Model

[0003] In order to overcome the above deficiencies, the utility model provides an intelligent water path distributor. Multiple water paths can be opened randomly without following a sequence, and multiple water paths can also be opened simultaneously. The operation of opening the water path is convenient, and the water path distributor is flexible and convenient to use. Compared with the initial product that can only clean one at a time, the water outlet and cleaning efficiency are significantly improved.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: An intelligent water path distributor includes a distributor body. A main shaft, a ratchet wheel, a turbine wheel, and several spray nozzles arranged at circumferential intervals are installed on the distributor body. A water valve is provided on the spray nozzle, and a valve rod for opening and closing the water valve is provided on the water valve. The turbine wheel and the main shaft are circumferentially locked. A relief groove for allowing the main shaft to pass through is provided on the ratchet wheel, and the main shaft drives the ratchet wheel to rotate unidirectionally; A top block that moves is connected to the ratchet wheel. When the ratchet wheel and the turbine wheel rotate together, the top block is aligned with the valve rod. When the turbine wheel rotates reversely alone, it pushes the top block to move, so that the top block pushes the valve rod to move to open the water valve.

[0005] Each nozzle on the water path distributor corresponds to a water path, and the opening and closing of the water valve realize the on-off of the water path corresponding to the nozzle. In the initial state, the top block retracts and all water valves are closed. When a certain water valve needs to be opened, the main shaft rotates, driving the ratchet disc and the turbine disc to rotate together so that the top block aligns with the valve stem. Then the main shaft rotates in the reverse direction. Due to the influence of the ratchet structure principle, the ratchet disc rotates in one direction. At this time, the turbine disc rotates in the reverse direction with the main shaft, while the ratchet disc remains stationary. Since a relief groove is provided on the ratchet disc, it prevents interference with the main shaft when the main shaft rotates in the reverse direction. The turbine disc rotates alone in the reverse direction to push the top block to move, so that the top block pushes the valve stem to move and thus opens the water valve. The water valves installed on several nozzles are independent. When you want to open a certain water valve, you only need to rotate the top block to the corresponding water valve position, and multiple water valves can be opened simultaneously. After the water valve is opened, the controller controls the water pump to start sending water, and the corresponding nozzle can spray water to clean the detection head on the vehicle. The intelligent water path distributor of this patent application can realize the random opening of multiple water paths, and multiple water paths can be opened simultaneously. The operation of opening the water path is convenient, and the water path distributor is flexible and convenient to use.

[0006] Preferably, a guide groove is provided on the turbine disc, and the guide groove is arranged along the circumferential direction away from the main shaft. A guide post is provided on the top block, and the guide post is inserted and connected with the guide groove. When the turbine disc rotates, the guide groove pushes the guide post and the top block to move outward together.

[0007] When the turbine disc rotates alone in the reverse direction, the ratchet disc remains stationary, and the guide groove provided on the turbine disc is arranged along the circumferential direction away from the main shaft. Therefore, during the rotation of the guide groove with the turbine disc, it can push the guide post and the top block to move outward together, so that the top block presses against the valve stem to open the water valve.

[0008] Preferably, a limit convex block is provided on the main shaft, and the limit convex block is placed in the relief groove. When the main shaft drives the turbine disc to rotate alone, the limit convex block moves in the relief groove; when the main shaft drives the ratchet disc and the turbine disc to rotate together, the limit convex block abuts against one end of the relief groove.

[0009] The setting of the limit convex block enables the main shaft to drive the ratchet disc to rotate when it rotates forward. When the main shaft rotates in the reverse direction, the limit convex block can slide in the relief groove to avoid jamming interference.

[0010] Preferably, a locking mechanism is correspondingly installed on the distributor body and the water valve. The locking mechanism includes a locking pin and a positioning spring. A locking groove is provided on the valve stem. After the top block pushes the valve stem to move and open the water valve, the locking pin is inserted into the locking groove to lock the valve stem; a push plate for pushing the locking pin to move out of the locking groove is provided on the ratchet disc.

[0011] After the top block moves outward to push the valve stem to open the water valve, the locking pin is pushed by the positioning spring to be inserted into the locking groove to lock the valve stem, so that the water valve is always in the open state.

[0012] Preferably, an inclined pushing surface is provided on the push plate. During the rotation of the ratchet disc, the pushing surface can contact the locking pin and lift the locking pin. The push plate and the top block are circumferentially misaligned, and the top block is placed behind the push plate along the rotation direction of the ratchet disc.

[0013] After the detection head on the vehicle is cleaned, the ratchet disc and the turbine disc rotate one week together with the main shaft. During this process, the pushing surface on the push plate contacts the locking pin and lifts the locking pin out of the locking groove. The locking pin loses its positioning of the valve stem, and the valve stem returns to its original position to close the water valve.

[0014] Preferably, a circle of ratchet teeth grooves is provided on the periphery of the ratchet disc on the distributor body, and a ratchet pawl is installed on the ratchet disc, and the end of the ratchet pawl is placed in the ratchet teeth groove.

[0015] When the ratchet disc rotates with the main shaft, the ratchet pawl can disengage from the ratchet teeth groove. When the main shaft rotates in reverse, the ratchet pawl gets stuck in the ratchet teeth groove, thereby realizing the locking of the ratchet disc.

[0016] Preferably, a valve cavity is provided in the water valve, an inclined sealing surface is provided in the valve cavity, a piston is installed in the valve cavity, the valve stem is connected to the piston, a valve flap is installed on the piston, a water inlet nozzle and a water outlet nozzle are provided on the water valve, the water inlet nozzle and the water outlet nozzle are respectively communicated with the valve cavity on both sides of the sealing surface, and a pre-tightening spring is installed in the valve cavity, and the pre-tightening spring abuts against the piston to make the valve flap fit on the sealing surface.

[0017] Under the action of the pre-tightening spring, the valve flap closely fits on the sealing surface provided in the valve cavity, thereby closing the water valve. After the valve stem is pushed by the top block, the piston moves in the valve cavity, separating the valve flap from the sealing surface, and the water valve opens.

[0018] Preferably, a number of magnetic sensors are installed in the distributor body corresponding to the water valves one by one, and magnetic blocks are provided corresponding to the top blocks on the turbine disc, and the magnetic sensors can sense the magnetic blocks.

[0019] After determining the position of the spray nozzle to be opened, the turbine disc and the ratchet disc rotate together with the main shaft. When the top block rotates to the position aligned with the valve stem, the magnetic block is detected by the magnetic sensor at the position of the valve stem, thereby determining that the top block is in place. Then the main shaft drives the turbine disc to rotate 180 degrees in reverse to open the water valve. At this time, after the magnetic block is detected by the magnetic sensor again, it is determined that the water valve is opened.

[0020] Preferably, the distributor body includes an upper housing and a lower housing. An upper cover and a lower cover are installed between the upper housing and the lower housing, a sealing member is installed between the upper cover and the lower cover, and the spray nozzle is installed between the upper cover and the lower cover.

[0021] This structural setting of the distributor body facilitates the installation of the spray nozzle.

[0022] Preferably, a water inlet pipe is connected to the lower housing, a water storage cavity is arranged on the lower housing, a plurality of water pipes are arranged on the sealing member corresponding to the water spray nozzles one by one, water through holes are arranged on the lower cover corresponding to the water pipes, the water pipes are hermetically connected to the water through holes, and the water pipes communicate between the water spray nozzles and the water storage cavity.

[0023] Water flows from the water inlet pipe to the water storage cavity, and is communicated with the water spray nozzles through the water through holes. Only when the water valve on the water spray nozzle is opened can the water spray nozzle spray water outwards.

[0024] Compared with the prior art, the beneficial effects of the present utility model are as follows: (1) The intelligent water path distributor of this patent application can realize the random opening of multiple water paths, and multiple water paths can also be opened simultaneously. The operation of opening the water paths is convenient, and the water path distributor is flexible and convenient to use; (2) After the water valve is opened, the locking pin is pushed by the positioning spring and inserted into the locking groove to lock the valve rod, so that the water valve is always in the open state. Then, the top block can perform the opening operation on other water valves to realize the opening of multiple water paths. Description of the Drawings

[0033] The technical solution of the present utility model will be further specifically described below through specific embodiments in conjunction with the drawings:

An upper cover 8 and a lower cover 9 are installed between the upper housing and the lower housing, and a seal 10 is installed between the upper cover and the lower cover. The water spray nozzles are installed between the upper cover and the lower cover. The lower housing is connected with a water inlet pipe 11, and a water storage chamber 12 is arranged on the lower housing. A plurality of water passing pipes 13 corresponding to the seals and the water spray nozzles are arranged on the seal, and water passing holes 14 corresponding to the water passing pipes are arranged on the lower cover. The water passing pipes are hermetically connected to the water passing holes, and the water passing pipes communicate between the water spray nozzles and the water storage chamber. A driving motor 15 is installed on the distributor body, the output shaft of the driving motor is connected with a worm 16, the main shaft is connected with a worm gear 17, and the worm is in transmission connection with the worm gear. A motor base 18 is installed in the upper housing, and the driving motor is installed on the motor base. The upper end of the upper housing is connected with an end cover 19, and a circuit board 20 is installed between the end cover and the motor base.

[0035] A water valve is arranged on the water spray nozzle. A valve stem 21 for opening and closing the water valve is arranged on the water valve. A valve cavity 22 is arranged in the water valve, an inclined sealing surface 23 is arranged in the valve cavity, a piston 24 is installed in the valve cavity, the valve stem is connected with the piston, a valve flap 25 is installed on the piston, a water inlet nozzle 26 and a water outlet nozzle 27 are arranged on the water valve, the water inlet nozzle and the water outlet nozzle are respectively communicated with the valve cavity on both sides of the sealing surface, a pre-tightening spring 28 is installed in the valve cavity, and the pre-tightening spring abuts against the piston to make the valve flap fit on the sealing surface. The water inlet nozzle is correspondingly connected with the water passing hole on the lower cover.

[0036] The turbine disk is placed below the ratchet disk. The turbine disk and the main shaft are circumferentially locked. A relief groove 29 for the main shaft to pass through is provided on the ratchet disk. The relief groove is in a semi-circular annular structure. The main shaft drives the ratchet disk to rotate unidirectionally. A limit lug 30 is provided on the main shaft, and a clamping groove 31 corresponding to the limit lug is provided on the ratchet disk. The limit lug is adaptively connected to the clamping groove and is placed in the relief groove. When the main shaft drives the turbine disk to rotate alone, the limit lug moves in the relief groove. When the main shaft drives the ratchet disk and the turbine disk to rotate together, the limit lug abuts against one end of the relief groove. A circle of ratchet teeth grooves 32 is provided on the outer periphery of the ratchet disk of the distributor body. A ratchet pawl 33 is installed on the ratchet disk, and the end of the ratchet pawl is placed in the ratchet teeth groove. The ratchet teeth groove is provided on the lower cover, and a positioning torsion spring is installed between the ratchet pawl and the ratchet disk.

[0037] A top block 34 that is connected and movably arranged is installed on the ratchet disk. The top block can move radially. A sliding groove 35 corresponding to the top block is provided on the ratchet disk. A rib 36 is provided on the side wall of the sliding groove, and grooves 37 adapted to the rib are provided on the two side walls of the top block. The top block is slidably installed in the sliding groove, and the sliding groove is slidably adapted to the rib. A guide groove 38 is provided on the turbine disk. The guide groove is arranged circumferentially away from the main shaft. A guide post 39 is provided on the top block, and the guide post is inserted and connected to the guide groove. When the turbine disk rotates, the guide groove pushes the guide post and the top block to move outwards together. The guide groove extends 180 degrees circumferentially. When the ratchet disk and the turbine disk rotate together, the top block aligns with the valve stem. When the turbine disk rotates reversely alone, it pushes the top block to move, so that the top block pushes the valve stem to move and thus opens the water valve.

[0038] A locking mechanism is installed on the distributor body corresponding to the water valve. The locking mechanism includes a locking pin 40 and a positioning spring 41. A locking groove 42 is provided on the valve stem. After the top block pushes the valve stem to move and open the water valve, the locking pin is inserted into the locking groove to lock the valve stem. A push plate 43 for pushing the locking pin to move out of the locking groove is provided on the ratchet disk. An inclined pushing surface 44 is provided on the push plate. During the rotation of the ratchet disk, the pushing surface can contact the locking pin and lift the locking pin. The push plate is circumferentially misaligned with the top block, and along the rotation direction of the ratchet disk, the top block is placed behind the push plate.

[0039] A number of magnetic sensors 45 are installed in the distributor body corresponding to the water valves one by one. Magnetic blocks 46 corresponding to the top block are provided on the turbine disk. The magnetic sensors can sense the magnetic blocks.

[0040] Each water spray nozzle on the water path distributor corresponds to a water path, and the opening and closing of the water valve realize the on-off of the water path corresponding to the water spray nozzle. In the initial state, the top block retracts and all water valves are closed. When a certain water valve needs to be opened, the driving motor drives the main shaft to rotate, driving the ratchet disc and the turbine disc to rotate together so that the top block aligns with the valve stem, and the magnetic inductor is used to sense the magnetic block to judge the rotation in place. Then the main shaft rotates in the reverse direction. Since the main shaft can only drive the ratchet disc to rotate in one direction, at this time the turbine disc rotates in the reverse direction together with the main shaft, while the ratchet disc remains stationary. Since a relief groove is provided on the ratchet disc, it prevents interference with the main shaft when the main shaft rotates in the reverse direction. The turbine disc rotates reversely alone, and through the cooperation of the guide groove and the guide post, the top block is pushed to move radially outward, so that the top block pushes the valve stem to move to open the water valve. After the magnetic block is detected by the magnetic inductor again, it is judged that the water valve is fully opened. The water valves installed on several water spray nozzles are independent. When you want to open a certain water valve, you only need to rotate the top block to the position corresponding to the water valve, and multiple water valves can be opened simultaneously. After the water valve is opened, the controller controls the water pump to start sending water, and the corresponding water spray nozzle can spray water to clean the detection head on the vehicle.

[0041] After the detection head on the vehicle is cleaned, the ratchet disc and the turbine disc rotate one week together with the main shaft. During this process, the pushing surface on the push plate contacts the locking pin and pushes the locking pin up to disengage from the locking groove. The locking pin loses the positioning of the valve stem, and under the action of the pre-tightening spring in the valve cavity, the valve stem returns to its position to close the water valve. The intelligent water path distributor of this patent application can realize the random opening of multiple water paths, and multiple water paths can be opened simultaneously. The operation of opening the water path is convenient, and the water path distributor is flexible and convenient to use.

[0042] The above-described embodiments are only the preferred solutions of the present invention, and do not impose any form of limitation on the present invention. There are other variations and modifications without exceeding the technical solutions described in the claims.
