[0002] As the number of cars increases, car wash machines are increasingly used in commercial complexes, communities, hotels and other scenarios. During the car wash process, car owners often bring pet hair, clothing fibers, or use plastic bags to wrap items into the car wash area, causing the following problems:

[0003] 1. When the car washing machine is washing the vehicle, the sewage generated will flow into the underground drainage pipe along the floor drain of the car washing area. Some car washing areas simply install floor drains at the ground drainage outlets, and some car washing areas will install drainage valves at the ground drainage outlets. The purpose of installing drainage valves is to intercept and precipitate the water generated by car washing, and then use the precipitated water as reclaimed water for the second time to achieve water conservation. However, there are often some problems when the water that is to be discharged into the underground pipeline passes through the drainage valve, such as flexible foreign matter entanglement: the internal flow channel of the drainage valve is narrow, and hair and plastic bag fragments are easily entangled on the valve stem, filter screen or sealing ring, causing the valve to be stuck or not sealed tightly;

[0004] 2. Environmental pollution risk: If the drain valve is blocked to a certain extent, the seal will fail, which may cause sewage to flow back and pollute the ground and groundwater of the car wash;

[0035] The solution of this embodiment, as Figures 1 - 3 shown, provides a clog - proof drainage valve for a car washer, including a drainage part 3, a cylinder 1 and a rotating part 6. The drainage part 3 has a drainage hopper 301. A support skeleton 302 and a mounting plate 303 are arranged at the upper opening of the drainage hopper 301. The drainage hopper 301 is fixedly installed through the mounting plate 303, and the drainage hopper 301 is installed at the lower part or the bottom of the water storage facility of the car washer; The cylinder 1 is located above the drainage part 3 and is fixedly connected to the support skeleton 302. The support skeletons 302 are arranged in a circular array centered on the rotating shaft 601, and the cross - section of the support skeleton 302 has an arc surface, and water flows through the gaps formed between the support skeletons 302; The rotating part 6 is arranged in the middle of the cylinder 1, and the rotating part 6 has a rotating shaft 601 passing through the cylinder 1, and a cutting part is arranged at the lower end of the rotating shaft 601. The cutting part cuts and segments sundries such as hair flowing into the drainage hopper 301 through the gaps of the support skeleton 302. The cutting part includes driving blades 7. The driving blades 7 are arranged in a circular array centered on the rotating shaft 601, and the driving blades 7 are inclined relative to the axis of the rotating shaft 601 on the outer peripheral surface of the rotating shaft 601. Thus, when water flows into the drainage hopper 301 and impacts the driving blades 7, the driving blades 7 can be driven to rotate. This structure is similar to an impeller generator installed at the water release place of a water gate. The flow of water impacts the blades to rotate, and then magnetic field cutting is carried out for power generation. This structure is prior art, as Figure 5 shown in, a number of equally - spaced missing teeth 701 are arranged at the edge of the driving blade 7, and a cutter 7011 is arranged in the missing teeth 701. Since when the rotating shaft 601 and the driving blade 7 rotate, the winding will only become tighter and tighter as it rotates. The cutter 7011 cuts off the winding sundries such as hair. Among them, it should be noted that the driving blade usually rotates at a relatively high speed under the push of water flow. When hair touches the driving blade, the inertia generated by the high - speed rotation of the driving blade will quickly tighten the hair; Since the driving blade keeps rotating, the hair cannot be loosened in time, resulting in an increase in the number of winding turns. At the same time, the missing teeth on the driving blade can better intercept and wind some winding objects such as hair. Therefore, when winding objects such as hair wind around the missing teeth, the winding object becomes tighter and tighter. After contacting the cutter 7011, the hair is directly cut off, so as to ensure that the winding object does not have enough length to wind again, and at the same time avoid the winding object winding around the rotating shaft. A connecting part 2 is arranged at the upper end of the rotating shaft 601. When the flow rate of the flowing liquid is insufficient or the flow velocity is too slow to support the rotation of the driving blade 7, a driving motor can be connected through the connecting part 2 for driving to assist in rotation.

[0036] Embodiment 2:

[0037] Compared with the previous embodiment, other mechanisms are provided in this embodiment on the basis of the previous embodiment: a telescopic rod 8 that can move up and down is provided at the lower part of the rotating shaft 601. At the same time, a movable cavity is provided in the driving blade 7, and a blade 702 corresponding to the missing teeth 701 is provided in the movable cavity. Interleaved cutter teeth 703 are provided at the edge of the blade 702. The cutter teeth 703 can cut through the gaps of the missing teeth 701, so as to cut off the entangled winding objects.

[0038] It should be further noted that a curved ring groove 101 and a limiting rod 602 are provided on the inner wall of the cylinder body 1. At least one limiting rod 602 is provided. One end of the limiting rod 602 is fixedly connected to the rotating shaft 601, and the other end of the limiting rod 602 is located in the curved ring groove 101 and can slide along the curved ring groove 101. When the rotating shaft 601 rotates and drives the limiting rod 602 to rotate, the end of the limiting rod 602 slides along the curved ring groove 101 to realize the up and down movement of the rotating shaft 601, so as to form a shearing state at the lower part.

[0039] It should be further noted that as Figure 3 、 Figure 5 and Figure 8 shown, the driving blade 7 has a movable cavity 802 with an opening on one side. The lower end of the rotating shaft 601 is provided with a telescopic cavity 604 with a downward opening. The telescopic cavity 604 is communicated with the movable cavity 802. A telescopic rod 8 that moves up and down along the telescopic cavity 604 is provided in the telescopic cavity 604. The blade 702 is provided in the movable cavity 802, and the blade 702 can move up and down in the movable cavity 802. Interleaved cutter teeth 703 corresponding to the missing teeth 701 are provided at the edge of the blade 702. When the blade 702 moves up and down, the cutter teeth 703 cooperate with the missing teeth 701 to form a shear opening, and the cutting edges of the cutter teeth 703 face the missing teeth 701 on both sides. The telescopic rod 8 is fixedly connected to the blade 702. The length of the blade 702 is less than the length of the movable cavity 802, and the cutter teeth 703 and the missing teeth 701 are arranged in an interleaved manner. The telescopic movement of the telescopic rod 8 can drive the blade 702 to move up and down in the movable cavity 802. At the same time, the telescopic rod 8 will also rotate accordingly. It should be noted that as Figure 7As shown, the cross-section of the driving blade 7 is trapezoidal or rectangular; at the same time, a cross bar 5 is arranged in the drain hopper 301. When the water flow impacts and drives the blade 7 to rotate, the limiting rod 602 will move along the curved ring groove 101 during rotation, so that the rotating shaft 601 can move up and down. A cross bar 5 is arranged in the drain hopper 301, and the middle of the cross bar 5 is directly opposite to the lower end of the telescopic rod 8. The cross bar 5 can resist the lower end of the telescopic rod 8, so that when the rotating shaft 601 moves downward, the telescopic rod 8 can be stressed to make the cutter teeth 703 cut off the entangled objects. A top cap 801 is arranged at the lower end of the telescopic rod 8. The cross-section of the top cap 801 is trapezoidal, and the material of the top cap 801 is metal or rubber. When the top cap 801 is metal, such as lead sheet or iron, when the rotating shaft 601 moves upward, the telescopic rod 8 can move downward under the influence of gravity, so as to ensure the opening and closing of the cutter teeth 703 and the missing teeth 701 and realize shearing.

[0040] It should be further noted that a spring 9 is arranged in the telescopic cavity 604. One end of the spring 9 is fixedly connected to the telescopic cavity 604, and the other end is connected to the telescopic rod 8. At this time, the top cap 801 can be made of rubber material, which can buffer the force on the telescopic rod 8. During use, the initial state of the spring is a compressed state. When the rotating shaft 601 rotates and moves upward, the elastic force of the compressed spring 9 is released, and the elastic force of the spring 9 pushes the telescopic rod 8 downward. When the rotating shaft 601 moves downward, the telescopic rod 8 will relatively push the spring 9 to make the spring 9 stressed and compressed, and so on repeatedly.

[0041] Embodiment 3:

[0042] When the rotating shaft stops rotating, an electromagnet 13 is arranged at one end of the telescopic cavity 604. One end of the telescopic rod 8 facing the electromagnet 13 is provided with an iron sheet or a magnet, and the up and down movement of the telescopic rod 8 is controlled by the electromagnet 13, as Figure 9 As shown, it is controlled by a plc control circuit. Under normal circumstances, the electromagnet 13 adsorbs with the iron sheet at the top of the telescopic rod 8, so that the telescopic rod 8 always remains in a retracted state. When there are entangled objects in the missing teeth 701 of the driving blade 7, the sewage outlet 10 is controlled to open, and the solenoid valve 12 of the water connection pipe 11 is closed. The electromagnet 13 changes its magnetic pole. At the same time, under the action of the spring 9, the blade 702 can cooperate with the missing teeth 701 to cut off the entangled objects, and at the same time discharge them from the sewage outlet 10. After the sewage outlet 10 discharges, the telescopic rod 8 is fixed by the electromagnet 13, the sewage outlet 10 is closed, and the solenoid valve 12 is opened to continue draining water.

[0043] It should be further noted that symmetric limiting blocks 603 are provided at the upper end of the rotating shaft 601. Strip-shaped grooves 201 are provided on both sides of the connecting member 2. The limiting blocks 603 are arranged in the strip-shaped grooves 201. When the pressure of the water cannot drive the driving blade 7 to rotate, the connecting member 2 is connected to the driving motor for driving assistance. At the same time, when the rotating shaft 601 moves up and down, the limiting blocks 603 can move up and down in the strip-shaped grooves 201 without affecting the rotation of the rotating shaft 601.

[0044] Working principle of the present invention:

[0045] During use, the mounting plate 303 is installed at the bottom of the reservoir or water storage tank. When draining water outwards, the water connection pipe 11 connecting the water outlet cylinder 4 is opened. When water flows into the water outlet cylinder 4, the flow of the water will push the driving blade 7 to rotate. Tooth notches 701 are provided at the edge of the driving blade 7. When the driving blade 7 rotates, the tooth notches 701 can wind hair or plastic impurities. When the driving blade 7 drives the entire rotating shaft 601 to rotate, since a limiting rod 602 is provided at the upper end of the rotating shaft 601, the limiting rod 602 is installed in a curved ring groove 101 provided inside the cylinder body 1. When the rotating shaft 601 rotates through the water flow, the limiting rod 602 continues to move up and down along the track of the curved ring groove 101, thereby driving the rotating shaft 601 to achieve the effect of moving up and down. At the same time, a telescopic rod 8 is provided at the bottom of the rotating shaft 601. The telescopic rod 8 is fixedly connected to the blade 702. And the driving blade 7 has a movable cavity 802. The blade 702 is arranged in the movable cavity 802. When the rotating shaft 601 moves upwards, the telescopic rod 8 moves downwards under the influence of gravity, and the tooth notches 701 and the cutter teeth 703 are staggered, and the wound hair or broken plastic enters the tooth notches 701; when the rotating shaft 601 moves downwards, the telescopic rod 8 moves upwards relatively, and the cutter teeth 703 cut through the hair or broken plastic wound in the tooth notches 701, so that the winding is more broken, thus avoiding meeting the winding length, thereby avoiding the situation of pipeline blockage and winding of the rotating shaft; at the same time, a sewage outlet 10 and a water connection pipe 11 are provided on the water outlet cylinder 4. An electromagnetic valve 12 is connected in the water connection pipe 11. When there are too many winding objects or impurities, the electromagnetic valve 12 is electrically controlled to be closed and the sewage outlet 10 is opened to directly discharge the sheared winding objects; through the above description, the achieved effect is that the driving blade rotates through the impact of the water flow on the driving blade, and the driving blade intercepts and winds winding objects such as hair while rotating; at the same time, the rotating shaft rotates; thereby driving the telescopic rod to move up and down, realizing that the cutter teeth of the cutter body cut the tightly wound hair and winding objects, and avoiding the winding of the winding objects.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
