The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-8, an ash removing device for a vacuum heat collecting outer tube of a solar water heater comprises a support 1, wherein a water tank 2 is fixedly connected to the upper end of the support 1, a heat collecting tube 3 is fixedly connected to the lower side end of the water tank 2, a photo resistor 4 is fixedly connected to the upper surface of the heat collecting tube 3, a motor 5 is fixedly connected to the upper left end of the support 1, two ends of the photo resistor 4 are electrically connected to two ends of the motor 5, when the photo resistor 4 is blocked from receiving light, the motor 5 operates, otherwise, the rotation stops.
The rotor end of the motor 5 is fixedly connected with a threaded shaft 6, two ends of the heat collecting tube 3 and the threaded shaft 6 are respectively and fixedly connected with a conversion disc 7, the inner side surface of the inner ring of the conversion disc 7 is fixedly connected with a bulge 71, and the diameter of the bulge 71 is matched with the width of the inclined groove 813. The projections 71, when contacting the angled slots 813, will guide the chuck 81 in rotation.
The right end of the first jaw 9 is fixedly connected with a cleaning layer 92, the outer ring of the threaded shaft 6 is movably clamped with a second jaw 10 through a chuck 81, the number of the first jaw 9 and the number of the second jaw 10 are four respectively, and the four jaws are uniformly distributed on the outer surfaces of the heat collecting tube 3 and the threaded shaft 6 respectively. The four first clamping jaws 9 and the four second clamping jaws 10 stabilize the movement of the structure, and effective cleaning of the heat collecting pipe 3 is ensured.
The lower end of the second jaw 10 is provided with a third thread 101, the right end of the second jaw 10 is provided with a fourth thread 102, and the fourth thread 102 is matched with the threads on the threaded shaft 6. The thread on the threaded shaft 6 will guide the second jaw 10 in its movement and at the same time bring the entire cleaning device 8 along.
The two ends of the second thread 91 and the third thread 101 are fixedly connected with sliding protrusions 11, and the sliding protrusions 11 are matched with the sliding grooves 812. The slide 812 guides the first jaw 9 and the second jaw 10 to move around a circle, tighten and release.
A connecting block 12 is fixedly connected between the cleaning devices 8. The connecting block 12 will connect all the cleaning devices 8 together
The working principle is as follows: when the dust on the surface of the heat collecting tube 3 is accumulated enough, the light dependent resistor 4 cannot effectively receive sunlight, the resistance is changed, the motor 5 starts to work and drives the threaded shaft 6 to rotate, because the thread four 102 is arranged on the side surface of the jaw two 10 inside the cleaning device 8, and the jaw two 10 is tightened inwards, the thread four 102 on the side surface is tightly attached to the threaded shaft 6, the whole cleaning device 8 is driven to move upwards along the threaded shaft 6, the jaw one 9 moves upwards synchronously, and because the jaw one 9 is also tightened, the cleaning layer 92 on the side surface is tightly attached to the heat collecting tube 3, and in the process of continuously moving upwards, the cleaning layer 92 cleans the dust on the surface of the heat collecting tube 3, so that the cleaning effect is achieved.
The cleaning device 8 continuously ascends until the cleaning device ascends to the top end of the heat collecting pipe 3, the outer side of the chuck 81 is tightly attached to the inner side of the conversion disk 7, and the inclined groove 813 formed in the surface of the outer ring of the chuck 81 is clamped with the protrusion 71 fixedly connected with the inner ring of the conversion disk 7 and guides the chuck 81 to rotate. Because the first thread 811 on the surface of the chuck 81 is matched with the second thread 91 at the bottom end of the first jaw 9 and the third thread 101 at the bottom end of the second jaw 10, and simultaneously because the sliding groove 812 is matched with the sliding protrusion 11, the first jaw 9 and the second jaw 10 are guided to move outwards along the sliding groove 812 while the chuck 81 rotates, at the moment, the first jaw 9 and the second jaw 10 are not tightly attached to the heat collecting tube 3 and the threaded shaft 6 any more, the friction force between the first jaw 9 and the second jaw 10 is reduced to be minimum, and the cleaning device 8 is not forced upwards by the rotation of the threaded shaft 6. Meanwhile, the cleaning layer 92 finishes cleaning dust on the surface of the photo-resistor 4, the resistance value of the photo-resistor 4 is changed, the motor 5 does not work any more, and the cleaning device 8 slides downwards to the lowest end along the threaded shafts 6 of the heat collecting pipes 3 due to gravity.
When the cleaning device 8 is lowered to the lowest position, the inclined groove 813 formed in the outer ring surface of the chuck 81 is clamped with the protrusion 71 fixedly connected with the inner ring of the conversion disc 7 again, the chuck 81 is guided to rotate reversely, and similarly, the first clamping jaw 9 and the second clamping jaw 10 are tightened to the circle center position to clamp the heat collecting tube 3 and the threaded shaft 6 again, so that the dust removing process of the whole vacuum heat collecting outer tube of the solar water heater is completed.
In conclusion, the dust removing device for the vacuum heat collecting outer tube of the solar water heater is used by matching the photosensitive resistor 4, the motor 5, the threaded shaft 6, the conversion disc 7, the cleaning device 8, the chuck 81, the first clamping jaw 9, the second clamping jaw 10, the cleaning layer 92, the sliding projection 11 and the connecting block 12, so that the effect of automatically cleaning dust of the heat collecting tube is achieved, the problems that the solar energy collecting efficiency is low due to long-time dust deposition of the heat collecting tube and the bathing difficulty or the hot water using difficulty of a user is influenced are solved, in addition, manpower and material resources are saved, compared with the prior art, certain cost is saved, and the practicability of the device is improved.
