Description

Technical Field

[0001] The utility model belongs to the technical field of water meter actuators, and in particular relates to an integrated water meter actuator with a waterproof function. Background Art

[0002] The water meter actuator consists of mechanical components and transmission control parts. The mechanical components include the actuator housing, transmission system and switch device. The housing is made of engineering plastic materials and has the characteristics of waterproof, dustproof and impact resistance. The transmission control can realize precise control of the water meter switch. The water meter actuator can be used in conjunction with the smart home system to realize automatic water management and avoid waste of water resources.

[0003] The existing actuators on the market are all independent entities installed in the plastic shell of the instrument and cannot be directly installed on the base plate of the water meter. If they are directly installed on the base plate, the waterproof grade of the actuator is not high. The actuator itself is sealed by a sealing ring. If it is soaked in water for a long time, the sealing performance is very poor, which can easily cause water to enter the actuator and affect the normal operation of the actuator.

[0004] The existing actuators are single-layer waterproof, with poor IP performance, and the actuator body is prone to internal water ingress when working in a water environment for a long time, causing damage to internal components and affecting normal operation. Therefore, in view of the main defects that the existing actuators cannot be directly installed on the water meter base plate, the installation form is single and the installation operation is complicated and needs to be coordinated with the water meter shell, and the actuator itself lacks waterproof protection. It is urgent to design an integrated water meter actuator with high waterproof performance. Utility Model Content

[0005] The purpose of the utility model is to provide an integrated water meter actuator with waterproof function to solve the problems raised in the above background technology. The following technical solution is provided: an integrated water meter actuator with waterproof function, comprising:

[0006] The outer shell has a retaining wall at its upper end, the outer shell and the retaining wall surround a chamber with an upper opening, a switching assembly is provided on the lower side of the outer shell, a motor is provided inside the outer shell, and a switch is electrically connected to one end of the motor; the switch is used to control the start and stop of the motor, and a gear set is connected to the upper end of the motor; the upper end of the outer shell is sealed with a first sealing cover, and the top of the outer shell is sealed with a second sealing cover.

[0007] An axle fixing seat is fixedly arranged inside the retaining wall, a gear set is rotatably arranged on the axle fixing seat, and a motor and a switch are respectively fixedly arranged on the axle fixing seat, and the motor is used for driving the gear set to rotate.

[0008] In the present technical solution, the motor, gear set and switch are integrated into a shell in the utility model, the internal components are framed inside the shell by arranging a retaining wall inside the shell, and potting grooves are reserved at the circumferential edges of the first sealing cover and the second sealing cover respectively. By designing a wire outlet hole in the middle of the second sealing cover, the wire speed is pressed inside the first sealing cover. Therefore, even if the wire speed is pulled during the installation operation, the entire device will not come off.

[0009] By designing the first sealing cover and implementing the second layer of potting for the entire device, the line speed passes through the first sealing cover and the first sealing cover is glued and potted, thereby realizing the double potting of the device.

[0010] The actuator water meters on the market all have one layer of protection. The present application uses special organic silicone to respectively seal the first sealing cover and the second sealing cover, thereby achieving two layers of protection for the internal components.

[0011] In any of the above technical solutions, further, the first sealing cover can be sealed and embedded in the middle of the retaining wall, and a first glue groove is provided at the circumferential edge of the first sealing cover.

[0012] The second sealing cover can be sealed and embedded at the end of the retaining wall, and a second glue groove is arranged at the circumferential edge of the second sealing cover, and a wire outlet hole is also arranged in the middle of the second sealing cover.

[0013] In the technical solution, the first sealing cover and the second sealing cover are fixed to the outer shell by screws respectively, and the first glue groove and the second glue groove are reserved at the edge of the main body. When the first sealing cover and the second sealing cover are installed, the edges of the first sealing cover and the second sealing cover just fit with the retaining wall. When installing, the first sealing cover is first fixed to the outer shell by screws, and the first glue groove is filled with special organic silicone for the first time. After that, the second sealing cover is fixed to the top of the outer shell by screws again, and the second glue groove is filled with organic silicone for the second time. The first glue groove and the second glue groove share the same glue groove when filling, saving space.

[0014] The outlet wire passes through two layers of covers and through the outlet hole reserved in the middle of the second sealing cover, and the wiring extends out from it. After the installation is completed, the outlet hole is also sealed with silicone for waterproofing, and a wire outlet hole is also provided in the middle of the first sealing cover for leading the wire speed out of the switch.

[0015] The reason why water enters the actuators sold on the market is that during the production process, it is inevitable that they will be pulled, which will cause the wire roots and glue to fall off during use, resulting in water entering the actuator. In this practical application, the first layer of fixed wire grooves is reserved to achieve the first wire speed fixation, and then the wire speeds are passed through the outlet holes one by one into the second sealing cover, and then the second sealing cover is potted. The wire speed is separated by applying the second potting, and then the outlet hole is potted to achieve better glue wrapping of the wire speed. Even if the outer layer of the wire speed is torn, the inner layer still provides protection.

[0016] According to the IP68 waterproof rating, this device can be immersed in water for a long time at a depth of 1.2m without water ingress and failure through two potting. This ensures that the actuator is isolated from the external working environment, allowing the device to operate for a long time at a depth of 1.2m.

[0017] In any of the above technical solutions, further, the adapter assembly includes:

[0018] The adapter shaft is rotatably connected to the bottom of the housing, and the upper end of the adapter shaft is dynamically connected to the gear set, and the lower end of the adapter shaft is fixedly connected to the adapter plate. The upper end of the adapter shaft is sleeved with an axial sealing ring, and the lower end of the adapter shaft is sleeved with a radial sealing ring.

[0019] In the technical solution, two axial sealing rings are provided, which are respectively sleeved on the upper end of the adapter shaft. The waterproofness of the lower end of the device is better guaranteed by the three layers of sealing rings.

[0020] The beneficial effects of the utility model are as follows: the present application designs a first sealing cover and a second sealing cover, and respectively sets glue grooves at their respective edges, and uses silicone to achieve double-layer potting between the two glue grooves and the retaining wall; and cooperates with the two sealing rings set at the rotating shaft and the sealing ring set at the connecting base to achieve a higher IP waterproof protection level for the actuator, thereby ensuring that the actuator is isolated from the external working environment, so that the actuator can operate for a long time in an underwater environment.

[0030] An axle fixing seat 12 is fixedly disposed inside the retaining wall 11 , a gear set 50 is rotatably disposed on the axle fixing seat 12 , and a motor 30 and a switch 40 are respectively fixedly disposed on the axle fixing seat 12 , and the motor 30 is used to drive the gear set 50 to rotate.

[0031] In the present technical solution, the motor 30, the gear set 50, and the switch 40 are integrated in a shell, and the internal components are framed in the shell by arranging a retaining wall 11 inside the outer shell 10, and potting grooves are reserved at the circumferential edges of the first sealing cover 60 and the second sealing cover 70, respectively. By designing a wire outlet hole 72 in the middle of the second sealing cover 70, the wire speed is pressed inside the first sealing cover 60. Therefore, even if the wire speed is pulled during the installation operation, the entire device will not debond.

[0032] The first sealing cover 60 is designed to realize the second layer of potting of the entire device. The line speed passes through the first sealing cover 60 and the first sealing cover 60 is coated with glue for potting, thereby realizing the double potting of the device.

[0033] The actuator water meters on the market all have one layer of protection. The present application uses special organic silicone to respectively seal the first sealing cover 60 and the second sealing cover 70, thereby achieving two layers of protection for the internal components.

After the installation is completed, the wire outlet hole 72 is also sealed with silicone for waterproofing, and a wire outlet hole is also provided in the middle of the first sealing cover 60 for leading the wire speed out of the switch 40.

[0038] The reason why water enters the actuators sold on the market is that during the production process, it is inevitable that they will be pulled, which will cause the wire roots and glue to fall off during use, resulting in water entering the actuator. In the present invention, the first layer of fixed wire grooves is reserved to achieve the first wire speed fixation, and then the wire speeds are passed through the outlet holes 72 one by one into the second sealing cover 70, and the second sealing cover 70 is potted.
