Description

Technical Field

[0001] The utility model belongs to the field of recreational vehicles, and in particular relates to a recreational vehicle water tank structure with an isolation and thermal insulation layer. Background Art

[0002] The water purification tank in the RV is an indispensable part of the water use system. The function of the water purification tank is to store clean drinking water and domestic water. It is the main source of water for the RV. The water purification tank is generally installed on the chassis of the RV. The specific location varies from vehicle to vehicle, but it may also be installed under the booth or bed in the RV.

[0003] A caravan clean water tank in the prior art includes a water tank body, the water tank body is made of stainless steel, the inner wall of the water tank body is provided with a first water tank baffle, the inner wall of the water tank body is provided with a second water tank baffle, the inner wall of the water tank body is provided with a third water tank baffle, and the inner wall of the water tank body is provided with a heating pipe. The first water tank baffle, the second water tank baffle and the third water tank baffle are three wave-breaking plates, and are evenly distributed, and the water flow moves with inertia during the movement of the car.

[0004] In the prior art, the RV clean water tank, plastic water tank is generally manufactured by blow molding, and metal water tank is generally welded by single-layer stainless steel. For the clean water tank with single-layer structure, when used in the cold environment of winter, the water inside the clean water tank will freeze due to the low external ambient temperature, and the thermal insulation performance needs to be improved; at the same time, the amount of water stored in the clean water tank is generally above 100KG. When the RV is moving or braking, the water inside the water tank flows, and the inertial motion will form a water hammer effect. Hitting the water tank will not only cause a huge shaking sound, forming noise pollution, affecting the riding experience, but also the formed water hammer will damage the water tank and affect the service life of the water tank. Although the above-mentioned prior art solution is provided with three wave-breaking plates, the speed of the water flow is reduced by the fixed wave-breaking plates, but the wave-breaking plates blocking the water flow will still form a water hammer effect on the wave-breaking plates, forming a certain impact noise, and the prior art needs to be improved.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0033] The multilayer structure of the outer shell 1 also includes a cavity 4, with insulation layers 5 on both sides of the cavity 4, a reflective layer 7 on the outside of the insulation layer 5, a support layer 8 on the outside of the reflective layer 7, and a plurality of support rods 6 in the cavity 4, with both ends of the support rods 6 connected to the insulation layers 5 on both sides of the cavity 4.

The inert gas in the cavity 4 is argon.

[0034] The technical solution is to set a cavity 4 with a heat-insulating function inside the outer shell 1, and inject argon gas into the cavity 4. The argon gas has high density and dynamic viscosity, which slows down the heat convection and heat conduction in the cavity 4, thereby weakening the thermal conductivity of the cavity 4, and the heat transfer coefficient value is reduced. In addition, the thermal insulation layer 5 and the heat layer are set to achieve a better heat-insulating effect, thereby improving the thermal insulation effect of the water tank.

[0035] Embodiment 2:

[0036] Based on Example 1, refer to Figure 4-6 An edge stopper 92 is formed at the edge of the wave-breaking plate 9, and a gap is set between the wave-breaking plate 9 and the outer shell 1; elastic components 10 are provided on the upper and lower sides of the wave-breaking plate 9, and the elastic component 10 includes a tube body 101, one end of the tube body 101 is connected to the wave-breaking plate 9, and a moving rod 102 is slidably provided inside the other end of the tube body 101, and the other end of the moving rod 102 is connected to a connecting block 104, and the connecting block 104 is connected to the inner wall of the outer shell 1; a first spring 103 is provided on the outside of the tube body 101 and the moving rod 102, and one end of the first spring 103 is connected to the tube body 101, and the other end is connected to the moving rod 102.

[0037] At least one second spring 14 is provided inside the buffer chamber 12. One end of the second spring 14 is connected to the piston plate 11, and the other end is connected to the baffle 13. The air passage 16 on the baffle 13 can communicate the buffer chamber 12 and the air hole 15. The gas in the buffer chamber 12 is discharged through the air passage 16 and the air hole 15. A rubber ring 20 is provided inside the air passage 16. A sealing ball 19 is provided inside the rubber ring 20. The sealing ball 19 is sealed and slidably connected inside the rubber ring 20. A first vent 17 is provided on the baffle 13 at one end of the air passage 16 close to the buffer chamber 12, and a second vent 18 is provided on the baffle 13 at the other end of the air passage 16. A third spring 21 is connected to the side of the sealing ball 19 close to the second vent 18, and the other end of the third spring 21 is connected to the inner wall of the air passage 16; a fourth spring 22 is connected to the side of the sealing ball 19 close to the first vent 17, and the other end of the fourth spring 22 is connected to the inner wall of the air passage 16.

[0038] After water is filled in the outer shell 1, when the RV is driving or braking or starting, the water flows in the water tank due to inertia. When the flowing water passes through the wave-breaking plate 9, part of the water flow near the edge of the water tank is blocked by the edge block 92 of the wave-breaking plate 9, and at the same time, it continues to flow forward through the hollow channel 91 of the wave-breaking plate 9. The blocked part of the water flow is blocked by the edge block 92 to form a backflow, and the backflow fluid merges with the subsequent water flow entering the hollow channel 91. The backflow water flow is different from the subsequent water flow entering the hollow channel 91 in direction, and there will be a certain degree of diffusion effect. , forming a water vortex, which forms a swirling water flow between the two wave-breaking plates 9. This process not only slows down the flow rate of water and reduces the impact of water flow on the wave-breaking plates 9, but also the formed water vortex turns and stays between the two wave-breaking plates 9. The space between the two wave-breaking plates 9 will be filled with water, which further reduces the flow rate of water flow, prolongs the time that water stays between the wave-breaking plates 9, and reduces the impact of water hammer and the noise of water flow; and after the wave-breaking plates 9 are affected by the impact of water hammer, the elastic component 10 is provided to form a buffer and rebound of the water flow, which further reduces the effect of water hammer and has a better wave-proof effect.

[0039] When the water flow in the water tank flows to the two ends of the water tank, it impacts the piston plate 11, compresses the second spring 14 through the piston plate 11, and compresses the gas in the buffer chamber 12 at the same time. The pressure of the buffer chamber 12 gradually increases, forming a good buffer for the piston plate 11, which not only reduces the effect of water hammer, but also prevents the water flow from impacting the outer shell 1, further reduces the generation of noise, and prevents the outer shell 1 from being damaged by impact, thereby extending its service life; the above-mentioned process of preventing water hammer is as follows: the gas in the buffer chamber 12 enters the airway 16 through the first air vent 17, the pressure in the airway 16 increases, and pushes the sealing ball 19 to slide in the rubber ring 20. The sealing ball 19 is made of metal or plastic, the third spring 21 is compressed, and the fourth spring 22 is stretched. When the sealing ball 19 escapes from the rubber ring 20, the gas in the airway 16 passes through the second air vent 18 , the air in the buffer chamber 12 is released to prevent the pressure in the buffer chamber 12 from being too high, causing the piston plate 11 to stop moving and affecting the buffering effect on the water flow; when the water flow impacts the piston plate 11 and then flows back, the piston plate 11 moves in the opposite direction due to the rebound effect of the second spring 14, and a negative pressure is formed in the buffer chamber 12. The sealing ball 19 moves toward the buffer chamber 12 in the rubber ring 20, the fourth spring 22 is compressed, and the third spring 21 is stretched. When the sealing ball 19 is separated from the rubber ring 20 again, the external gas enters the buffer chamber 12 through the second air vent 18, the airway 16, and the first air vent 17, and the buffer chamber 12 is inflated until the air pressure in the buffer chamber 12 is balanced with that of the outside world. The sealing ball 19 is reset by the joint action of the third spring 21 and the fourth spring 22, and the sealing ball 19 forms a seal with the rubber ring 20 to prepare for the next buffering of the piston plate 11.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
