[0016] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0017] See attached Figures 1 to 4The utility model specifically proposes an auxiliary positioning and assembly device for a water volume sensor, including an upper flange clamping ear 30, an upper flange drilling bushing 31, an upper flange with a drilled hole 32, an upper flange main body 33, an upper flange fixing pin 34, an upper flange fixing boss 35, a support rod fixing groove 36, a main body support rod 37, a lower flange clamping ear 38, a lower flange drilling bushing 39, a lower flange with a drilled hole 40, a lower flange main body 41, a lower flange fixing boss 42, a lower flange fixing pin 43, a clamping plate fixing groove 44, a limiting fixing device 45, a fixing nut 46, a clamping device 47, a fixing shaft pin 48, etc.

[0018] 1. The upper flange body 33 is fixed above the main body support rod 37, and the clamping device 47 is fixed below the limit fixing device 45 for up and down adjustment.

[0019] 2. The upper flange body 33 can be firmly mounted on the upper portion of the main support rod 37, ensuring the stability and accuracy of the entire assembly. The design of the upper flange body 33 fully considers the interface matching with the finished water level sensor to achieve precise positioning and fixation.

[0020] 3. The upper flange body 33 is also equipped with an upper flange fixing pin 34 and an upper flange fixing boss 35. The design of these components enables the water level sensor to be firmly fixed on the assembly device to prevent displacement or loosening during assembly or use.

[0021] 4. The lower flange body 41 is also provided with a lower flange clamping ear 38, a lower flange drilling bushing 39, and a lower flange drilling hole 40. The design and arrangement of these components ensure the stability and accuracy of the water volume sensor during the assembly process.

[0023] The lower flange body 41 is also equipped with a lower flange fixing boss 42 that mates with the clamping plate fixing groove 44 and is used to form a fixed connection with the clamping device 47. The clamping device 47 cooperates with the limit fixture 45 via a fixed shaft pin 48, allowing the clamping device 47 to be adjusted up and down. The limit fixture 45 not only limits the adjustable position of the clamping device 47 on the support rod, but also serves as a reference installation position for the lower flange.

[0024] In specific applications, spacious space:

[0025] 1. Determine the installation position and dimensions according to the digital model. Remove the upper flange body 33 from the body support rod 37 and place it in the desired position. Use a bow clamp to secure the upper flange clamping ears 30 and upper flange drilling bushing 31 to the upper flange body 33. At this point, the upper flange countersunk holes 32 align with the holes in the upper flange drilling bushing 31, providing a precise positioning reference for subsequent assembly. Simultaneously, the upper flange fixing pins 34 and upper flange fixing bosses 35 are also ready for securing and supporting during assembly.

[0026] 2. Place the lower flange body 41 in the desired position, ensuring that the lower flange fixing bosses 42 precisely align with the lower flange clamping ears 38 and lower flange drilling bushings 39. Secure the lower flange body 41 to the desired position on the main support rods 37 using the lower flange fixing pins 43 to ensure assembly accuracy and stability. At this point, the lower flange countersunk holes 40 are aligned with the holes in the lower flange drilling bushings 39, preparing for subsequent installation steps.

[0027] 3. Insert the main support rod 37 into the support rod fixing groove 36 and secure it between the upper flange body 33 and the lower flange body 41 using the fixing nut 46 to form a stable support structure. This step completes the main structure of the water level sensor auxiliary positioning assembly device.

[0028] 4. Install the clamping device 47; the clamping device 47 is fixed to the main support rod 37 through a fixed shaft pin 48. The clamping device 47 includes a clamping plate, and a clamping plate fixing groove 44 is provided on the downward flange body 41 of the clamping plate. Its function is to fix and stabilize the position of the water level sensor during the assembly process to ensure the accuracy and reliability of the assembly.

[0029] Confined Spaces:

[0030] Installation is completed using only the upper flange body 33 and the lower flange body 41, the upper flange drilling bushing 31, and the lower flange drilling bushing 39. First, determine the installation position and dimensions according to the digital model. Remove the upper flange body 33 and the lower flange body 41 from the main body support rod 37 and secure them in place with a bow clamp. Place the upper flange drilling bushing 31 and the lower flange drilling bushing 39 into the upper flange matching drilling hole 32 and the lower flange matching drilling hole 40, respectively, to prepare for subsequent installation steps.
