Description

Technical Field

[0001] The utility model relates to the technical field of intelligent water meters, in particular to an antifreeze structure of an intelligent water meter. Background Art

[0002] Smart water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, smart IC card technology, etc. to measure water consumption, transmit water usage data and settle transactions.

[0003] Modern smart water meters are easily affected by the external environment during use, especially in low-temperature and freezing environments, such as the wild and rural areas in winter. Water meters are often frozen and cracked. The losses caused are often not limited to the cost of replacing the water meter, but also the waste of water resources. The consequences of flooding will cause environmental disasters and many inconveniences and difficulties in people's production and life. Moreover, when repairing and replacing a frozen and cracked water meter, the water meter and the front and rear end pipe sections need to be disassembled as a whole, which is time-consuming and labor-intensive, and the repair cost is high.

[0004] Existing smart water meters are structurally equipped with a water meter panel to protect the internal mechanical structure of the water meter, prevent water from seeping into the meter, and ensure the normal operation of the water meter. It is usually composed of a case, a middle cover, a watch glass and a sealing gasket to form a sealed body. The case material is generally gray cast iron or cast lead brass, and the case glass is tempered glass. The selection and design of these materials ensure that the water meter can withstand a certain water pressure. Although the use of the meter panel can also have a certain anti-freeze effect when it is frozen, the freezing environment will cause the water flow in the water meter to freeze and the volume of the ice cubes to increase. At this time, the meter panel will be squeezed and deformed. The deformation will cause the structure of the water meter counting gear box to be compressed, affecting its structural stability and also affecting the metering stability of the water meter.

[0005] Aiming at the problems existing in the background technology, an intelligent water meter antifreeze structure is proposed.

[0006] The utility model proposes an intelligent water meter antifreeze structure, comprising a water meter body, a through opening formed on the water meter body, the through opening being connected to a water cavity on the water meter body, an antifreeze base support assembly provided on the water meter body, the antifreeze base support assembly being used for sealing the through opening, the antifreeze base support assembly being composed of an elastic plastic plate and an airbag bowl, the elastic plastic plate being provided below the through opening for sealing the through opening, the airbag bowl being provided below the through opening for providing protection for the elastic plastic plate, and the airbag bowl being connected to the water meter body by adopting a threaded installation manner.

[0007] Preferably, when the expansion pressure in the water meter body does not exceed 2 MPa, the elastic plastic plate does not deform, and when the expansion pressure in the water meter body is between 2-4 MPa, the elastic plastic plate slowly deforms to expand part of the volume of the water cavity.

[0008] Preferably, when the expansion pressure in the water meter body exceeds 4Mpa and causes the elastic plastic plate to freeze and crack, the bottom air bag bowl can ensure the sealing of the water meter body.

[0009] Preferably, when the temperature rises, the elastic plastic plate restores itself.

[0010] Preferably, the water meter body is provided with external threads located on the periphery of the through hole, and the air bag bowl is provided with internal threads which are adapted to the external threads.

[0011] Preferably, the air bag bowl is provided with a sealing ring which is coaxially arranged with the through hole and is in contact with the water meter body, so as to improve the sealing of the through hole by the air bag bowl.

[0012] Preferably, a buffer interval is arranged between the bottom of the elastic plastic plate and the inner wall of the bottom of the air bag bowl, so as to provide space for the deformation of the elastic plastic plate.

[0013] Compared with the prior art, the utility model has the beneficial technical effects as follows:

[0014] Through the design of the elastic plastic plate, the air bag bowl and the water meter body, the original independence and stability of the water cavity of the water meter body can be maintained, the volume of the water cavity can be expanded under the condition of ice in the water meter body by the elastic performance of the elastic plastic plate, the sealing of the water cavity of the water meter body can be ensured, and the sealing can be restored in time after the temperature of the water body rises, so that the risk of freeze cracking of most water meters in a cold environment can be avoided, and the cost of using the water meter in a cold environment can be reduced.

[0015] Through the design of the air bag bowl, the water cavity can be sealed when the elastic plastic plate is broken, so that the structure constitutes the effect of double sealing and gives the water meter body the effect of bottom leakage prevention, and the harm of water leakage of the water meter body can be effectively prevented.

[0016] Through the design of the elastic plastic plate and the air bag bowl, when the water meter with freeze cracking is repaired, the whole water meter and the front and rear pipe sections do not need to be disassembled, and the water meter can be repaired by only replacing the anti-freezing bottom support, so that the maintenance cost is reduced, and the repair efficiency is improved.

[0017] The technical structure is simple and low in cost, the product produced by the technology is suitable for widely replacing the conventional water meter with a conventional glass meter plate, and is suitable for vigorous promotion. BRIEF DESCRIPTION OF DRAWINGS

[0021] like Figure 1-Figure 2 As shown, the utility model proposes an intelligent water meter antifreeze structure, which includes: a water meter body 1 and an antifreeze base assembly.

[0022] like Figure 1-Figure 2 As shown, a through hole is provided on the water meter body 1, and the through hole is provided at a lower position of the water meter body 1, and the through hole is communicated with the water cavity on the water meter body 1, and an antifreeze bottom support assembly is provided on the water meter body 1, and the antifreeze bottom support assembly is used to seal the through hole, and the antifreeze bottom support assembly is composed of an elastic plastic plate 2 and an air bag bowl 3, and the elastic plastic plate 2 is provided below the through hole to seal the through hole, and the air bag bowl 3 is provided below the through hole to provide protection for the elastic plastic plate 2. In actual use, the elastic plastic plate 2 and the air bag bowl 3 can be welded by ultrasonic welding, thereby improving the connection stability between the elastic plastic plate 2 and the air bag bowl 3, avoiding displacement of the elastic plastic plate 2 during use, and ensuring the stability of the elastic plastic plate 2. At the same time, the sealing effect between the elastic plastic plate 2 and the airbag bowl 3 is increased, which indirectly ensures the sealing effect of the water cavity on the water meter body 1, and the airbag bowl 3 is connected to the water meter body 1 by a threaded installation method. The water meter body 1 is provided with an external thread, and the external thread is located on the periphery of the through-port. The airbag bowl 3 is provided with an internal thread, and the internal thread is adapted to the external thread. Through the design of the antifreeze base assembly and the water meter body 1, the operational independence and stability of the water cavity on the water meter body 1 can be ensured. A sealing ring is provided in the airbag bowl 3, and the sealing ring is coaxially arranged with the through-port. The sealing ring contacts the water meter body 1, and the sealing performance of the airbag bowl 3 to the through-port is improved by the sealing ring. A buffer zone is provided between the bottom of the elastic plastic plate 2 and the bottom inner wall of the airbag bowl 3 to provide space for the elastic plastic plate 2 to deform.

[0023] like Figure 1-Figure 2 As shown, when the expansion pressure in the water meter body 1 does not exceed 2Mpa, the elastic plastic plate 2 does not deform. When the expansion pressure in the water meter body 1 is between 2-4Mpa, the elastic plastic plate 2 slowly deforms to expand part of the volume of the water cavity. In this case, the elastic plastic plate 2 will not rupture. When the expansion pressure in the water meter body 1 exceeds 4Mpa and causes the elastic plastic plate 2 to freeze and crack, the airbag bowl 3 at the bottom can ensure the sealing of the water meter body 1. When the temperature rises, the elastic plastic plate 2 recovers by itself.

[0024] In this embodiment, when in use, the elastic plastic plate 2 is first fixed to the airbag bowl 3 by ultrasonic welding, and then a sealing ring is placed in the airbag bowl 3. The sealing ring can be sleeved on the elastic plastic plate 2. Subsequently, the airbag bowl 3 is installed on the water meter body 1 by threaded rotation, and the opening on the water meter body 1 is wrapped. At this time, the elastic plastic plate 2 is in contact with the water meter body 1, and the opening is blocked.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
