Description

Technical Field

[0001] The invention belongs to the technical field of greening equipment, and in particular relates to a water intake valve capable of preventing freezing. Background Art

[0002] The water valve buried underground does not affect the landscape environment and can also prevent passers-by from abusing water. The quick water dispenser is used to temporarily take water from the underground pipe system. It can also be connected to a hose for manual irrigation or washing of vehicles and roads, etc. It is plug-and-play and stops when unplugged. It has an O-ring and has a good water-stopping effect.

[0003] Generally, water valves are installed around the lawns in residential communities. In cold winter, water often overflows from the water valves and is easily frozen into ice, which can clog water pipes. To prevent the water valves from freezing inside, foam covers are often placed on the outside. Foam covers are usually disposable, which is not good for the environment and is troublesome to use. Summary of the invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a water intake valve that can prevent freezing.

[0006] Preferably, two fixing rings corresponding to the upper heating plate and the lower heating plate are fixedly installed on the inner wall of the water intake valve body, and outer mounting rings are arranged on the outer sides of the upper heating plate and the lower heating plate.

[0010] Preferably, a thread groove is provided on the inner wall of the upper part of the water intake valve body, and the thread groove is used to connect other water pipes.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. Install a convex lens on the sealing cover of the water intake valve body. The convex lens has a light convergence effect, which converges the sunlight to heat the upper and lower heating plates inside. After heating, the ice inside can be effectively thawed, thereby ensuring the normal circulation of water. Automatic ice making also reduces the trouble of the staff; 2. The upper heating plate and the lower heating plate heat the water locally. If the water temperature is uneven, convection will occur. There is flowing water inside, which is difficult to freeze in a low temperature environment. It can also ensure the normal use of the water intake valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] Reference Figure 1-4, an antifreeze water intake valve, comprising: a water intake valve body 2 installed on the pool ground 1, the upper end of the water intake valve body 2 is rotatably connected with a sealing cover 4, the sealing cover 4 is provided with a card slot 6, a convex lens 5 is clamped in the card slot 6, a vacuum chamber 3 is opened on the inner wall of the water intake valve body 2, an upper heating plate 7 and a lower heating plate 8 are clamped on the inner wall of the water intake valve body 2, the upper heating plate 7 is arranged above the lower heating plate 8, a solid heating plate 11 is arranged on the upper heating plate 7, and a plurality of hollow holes 13 are arranged on the lower heating plate 8, the heating plate 11 and the holes 13 correspond to each other up and down, an isolation layer is arranged on the outer wall of the water intake valve body 2, the material of the isolation layer is thermal insulation cotton, the thermal insulation cotton has the effect of maintaining temperature, and protects the water temperature in the water intake valve body 2, and a threaded groove is arranged on the inner wall of the upper part of the water intake valve body 2, and the threaded groove is used to connect other water pipes externally.

[0016] In the embodiment of the above technical solution, two fixing rings 9 corresponding to the upper heating plate 7 and the lower heating plate 8 are fixedly installed on the inner wall of the water intake valve body 2, and an outer mounting ring 10 is provided on the outer side of the upper heating plate 7 and the lower heating plate 8. The outer mounting ring 10 is clamped in the fixing ring 9. The material of the fixing ring 9 is high-temperature resistant silicone. The high-temperature resistant silicone material is soft. After heating, the upper heating plate 7 and the lower heating plate 8 will deform due to the material itself. The fixing ring 9 made of soft material can adapt to the deformation of the upper heating plate 7 and the lower heating plate 8. At the same time, the fixing ring 9 also has the effect of fixing the upper heating plate 7 and the lower heating plate 8.

[0017] The preferred technical solution in this embodiment is that a connecting shaft 12 is arranged between the multiple heating plates 11, and the multiple heating plates 11 are fixedly connected to the inner wall of the outer mounting ring 10 through the connecting shaft 12. In order to avoid the heating plates 11 being in a suspended state and to ensure the stability of the heating plates 11, the connecting shaft 12 serves as an intermediate connecting structure, and a rotating groove is arranged at the rotating connection between the water intake valve body 2 and the sealing cover 4, and a rotating shaft is inserted in the rotating groove. The sealing cover 4 is rotatably connected to the rotating groove through the rotating shaft, and the rotating shaft is detachable. In summer, there is no need to use the convex lens 5 on the sealing cover 4, so the rotating shaft can be removed, thereby the sealing cover 4 can be replaced.

[0018] In winter, the temperature in the environment is low, and sunlight normally shines on the sealing cover 4. When the light shines on the convex lens 5, the upper and lower convex surfaces of the convex lens 5 have a convergence effect on the sunlight. The light passing through the convex lens 5 will converge to the center position. The transmitted sunlight has energy, and the converged light will shine on the center position of the upper heating plate 7, which has a heating effect on the heating plate 11 at the center position. The connecting shaft 12 connected around the heating plate 11 is made of graphene, which has a good thermal conductivity and can better transfer the solar energy absorbed at the center position to the surrounding heating plates 11. The surrounding heating plates 11 will also be heated, and then the temperature of the entire upper heating plate 7 will rise; The convex lens 5 has a convergence effect on light, but not all light will pass through in a vertical downward manner. The center point of light passing through from the side will be offset. In order to make full use of sunlight, a lower heating plate 8 is arranged below the upper heating plate 7. Both the lower heating plate 8 and the upper heating plate 7 have hollow parts, and the hollow parts are just staggered with each other, so that the upper and lower upper heating plates 7 and the lower heating plate 8 form a complete structure as a whole, so as to cover a certain range without affecting the normal circulation of water. When the upper heating plate 7 and the lower heating plate 8 are heated up, the water in the water intake valve body 2 will be affected by the temperature accordingly. If ice has already formed in the water intake valve body 2, the heated upper heating plate 7 and the lower heating plate 8 will have a heating effect on the water, thereby melting the ice and solving the problem of internal ice blockage by itself. If there is no ice, in a low temperature environment, the sunlight will heat the upper heating plate 7 and the lower heating plate 8 inside without hindrance. The local heating of the water body will cause convection. The flowing water is difficult to freeze in a low temperature environment, thereby effectively avoiding ice and blockage. The vacuum chamber 3 in the water intake valve body 2 has a heat-insulating effect, which reduces the loss of solar heat energy. In summer, there is no need to heat the water. The sealing cover 4 is detachable and can be replaced with an opaque structure.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
