Description

Technical Field

[0001] The present invention relates to the technical field of water meters, and in particular to a valve-controlled ultrasonic reflection water meter. Background Art

[0002] As we all know, to conserve water resources and control human waste, water meters are typically installed on household water pipes. Ultrasonic water meters use the principle of sound wave reflection to measure water flow velocity and volume. As water flows through the meter's measuring pipe, an ultrasonic sensor transmits sound waves into the water. When the sound waves encounter particles in the water, they reflect and are then received and reflected back. The ultrasonic sensor calculates the water flow velocity and volume based on the time it takes for the sound waves to reflect.

[0003] The main components of an ultrasonic water meter include a transmitter, receiver, acoustic sensor, controller, and memory. The transmitter and receiver are used to transmit and receive ultrasonic signals, respectively, while the acoustic sensor converts electrical signals into acoustic signals. The controller controls the meter's operation and stores measurement data.

[0004] Currently, most water meters typically use interfaces with various diameters, such as DN15, DN20, DN25, and DN32. DN15 corresponds to a pipe diameter of 20 mm, and similarly, DN20 corresponds to a pipe diameter of 25 mm. Consequently, during actual assembly, the meter must be tailored to the specific pipe diameters used in each household. Consequently, existing ultrasonic water meters struggle to adjust their diameters to the actual pipe diameters used, making it difficult to adapt to interfaces of varying diameters, resulting in a cumbersome assembly process. In light of this, we propose a valve-controlled ultrasonic reflection water meter. Summary of the Invention

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1.

[0029] 2. The valve-controlled ultrasonic reflection water meter is adjusted through the connecting flange interface. When the diameter of the interface is consistent with the diameter of the tee pipe, the flange at the interface needs to be docked with the connecting flange, and then the extrusion block and the anti-sliding block are pushed backward. When the gas enters the pressure relief pipe through the sliding sleeve, the pressure relief pipe will transport the gas to the sealing ring on one side of the connecting flange, so that the sealing ring is in an expanded state at this time, thereby increasing the friction inside the connecting bolts between the connecting flange and the flange at the interface, so that the water meter can automatically fill the gap when assembling the interface with the same inner diameter. At the same time, the stability of the water meter after assembly is guaranteed.

[0030] 3. This valve-controlled ultrasonic reflection water meter is equipped with a sealing assembly. When the piston disc moves to the left, the gas in the sealing tube is squeezed into the conduit. When it moves to the right, the sealing plate is pushed by pressure and flips along the rotating rod. When the piston disc moves to the left again, the sealing plate will drive the connecting sleeve to flip downward under the action of the elastic force of the coil spring, thereby sealing the through hole again. By arranging the sealing plate, coil spring and rotating rod on the surface of the piston disc, the sealing effect of the piston disc is guaranteed while ensuring that external gas can continue to enter the sealing tube.

[0050] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0051] Example: A valve-controlled ultrasonic reflection water meter, see Figures 1 to 9 ,include,

[0052] The water meter mechanism 1 includes a tee 101, a water meter display panel 102 disposed above the tee 101, an ultrasonic interface 103, and a connecting flange 104, wherein the ultrasonic structure is disposed outside the tee 101, and the connecting flange 104 is disposed outside the tee 101; and

[0053] The adjustment mechanism 2 includes a sealing tube 201, a fixing frame 202, a rotating assembly 203 disposed within the fixing frame 202, an adjustment assembly 204, and a sealing assembly 205, wherein the sealing assembly 205 is sleeved on the outside of the adjustment assembly 204, and one end of the rotating assembly 203 is connected to the corresponding end of the adjustment assembly 204; and

[0054] The assembly mechanism 3 includes a fixed plate 301, a pressure relief component 302 arranged on one side of the fixed plate 301, an extrusion component 303 and a reinforcement component 304, wherein the extrusion component 303 is connected to one end of the pressure relief component 302, and the bottom of the extrusion component 303 is connected to the top of the reinforcement component 304. The valve-controlled ultrasonic reflection type water meter, by setting the adjustment mechanism 2 and the assembly mechanism 3, can, on the one hand, fix the interface pipe through multiple reinforcement blocks 304-1, and squeeze the stainless steel gasket to preliminarily seal one side of the tee pipe 101; on the other hand, the volume of the expansion block 208-3 can be increased by inflating multiple expansion blocks 208-3, so that the gap between the interface, the stainless steel gasket and the tee pipe 101 can be filled through the expansion block 208-3, so that the water meter can not only dock interfaces of different calibers, but also achieve automatic sealing after docking, thereby reducing the difficulty of assembling the water meter.

[0055] Specifically, the top of the tee pipe 101 is connected to the water meter display panel 102, and the two ends of the tee pipe 101 are fixedly connected to two connecting flanges 104 respectively, and the two connecting flanges 104 are both connected to the tee pipe 101. There are several ultrasonic interfaces 103, and several ultrasonic interfaces 103 are tightly welded to the outside of the tee pipe 101. By setting the connecting flange 104 and opening a groove outside the connecting flange 104 to accommodate the extrusion block 303-1, it is ensured that the extrusion block 303-1 can move and be in the same plane with the connecting flange 104, thereby ensuring the stability of the movement of the extrusion block 303-1.

[0056] Furthermore, the inner wall of the sealing tube 201 is fixedly connected to the fixing frame 202, the fixing frame 202 and the rotating assembly 203 are mutually clamped, the rotating assembly 203 is composed of a bearing and a rotating shaft, one end of the rotating assembly 203 is fixedly connected to the corresponding end of the adjusting assembly 204, the other end of the rotating assembly 203 is fixedly connected to the turning handle 209, the sealing assembly 205 is clamped on the outside of the adjusting assembly 204, and the other end of the sealing assembly 205 is fixedly connected to two multi-section telescopic rods 206, and the other ends of the two multi-section telescopic rods 206 are fixedly connected to the adjusting assembly 204. The frame is fixedly connected to the sealing tube 201, and two conduits 207 are provided outside the sealing tube 201, and the other ends of the two conduits 207 are respectively connected to two connecting components 208. The sealing tube 201 is fixedly connected to the front of the tee pipe 101, and the connecting component 208 is sleeved on the outside of the tee pipe 101. Due to the use of a multi-section telescopic rod 206, it is ensured that the piston disc 205-1 will only move horizontally with the rotation of the adjusting rod 204-1, thereby preventing the piston disc 205-1 from rotating and affecting the discharge of gas in the sealing tube 201.

[0057] Furthermore, the adjustment component 204 includes an adjustment rod 204-1, and a limiting groove 204-2 is opened outside the adjustment rod 204-1. The shape of the limiting groove 204-2 is an ellipse opened along the outside of the adjustment rod 204-1. The sealing component 205 is sleeved on the outside of the adjustment rod 204-1, and one end of the adjustment rod 204-1 is tightly welded to the corresponding end of the rotating component 203. By setting the limiting groove 204-2 outside the adjustment rod 204-1, when the adjustment rod 204-1 rotates, the limiting block 205-8 will slide in the limiting groove 204-2, so that the piston disc 205-1 moves horizontally left and right, thereby ensuring the stability of the movement of the piston disc 205-1.

[0058] It is worth noting that the sealing assembly 205 includes a piston disc 205-1, and two through holes 205-2 are provided on one side of the piston disc 205-1. Four fixing plates 301 are fixedly connected to one side of the piston disc 205-1. Two fixing blocks 205-3 located at the same horizontal position are tightly welded with the same rotating rod 205-4. The outer cover of the rotating rod 205-4 is connected to a connecting sleeve 205-5. The outer cover of the connecting sleeve 205-5 is fixedly connected to a sealing plate 205-7. The position and shape of the sealing plate 205-7 are consistent with the position and shape of the through holes 205-2. Correspondingly, the outer surface of the rotating rod 205-4 is connected to the coil spring 205-6, and the two ends of the coil spring 205-6 are fixedly connected to the connecting sleeve 205-5 and the rotating rod 205-4 respectively. The piston disc 205-1 is fixedly connected to the limiting block 205-8. The piston disc 205-1 is sleeved on the outside of the adjusting rod 204-1, and the limiting block 205-8 is slidably connected to the limiting groove 204-2. The outer wall of the piston disc 205-1 and the inner wall of the sealing tube 201 overlap each other, and one side of the piston disc 205-1 is fixedly connected to the corresponding end of the two multi-section telescopic rods 206.

[0059] It is worth noting that the connecting assembly 208 includes a sleeve 208-1, and three connecting pipes 208-2 are fixedly connected to the outside of the sleeve 208-1, and the other ends of the three connecting pipes 208-2 are fixedly connected to the three expansion blocks 208-3 respectively. The sleeve 208-1 is connected to the three expansion blocks 208-3 through the connecting pipes 208-2. The sleeve 208-1 is sleeved on the outside of the three-way pipe 101, and the connecting pipe 208-2 is fixedly connected to the inside of the three-way pipe 101. The three expansion blocks 208 -3 are fixedly connected to the tee pipe 101, the sleeve 208-1 is connected to the sealing pipe 201 through the guide tube 207, the number of the fixing plates 301 is six, and one side of the six fixing plates 301 is fixedly connected to the corresponding side of the six pressure relief components 302, and the other end of the pressure relief component 302 is fixedly connected to the extrusion component 303. The bottom of the extrusion component 303 is tightly welded to the top of several reinforcement components 304. A telescopic tube 305 is fixedly connected to the extrusion component 303. When the cam 304 is in the closed position, the cam 304 is in the closed position, and the cam 304 is in the closed position, so that the cam 304 can be adjusted.

[0060] It is worth mentioning that the pressure relief assembly 302 includes two sleeves 302-1, and the two sleeves 302-1 are both slidably connected with a slide rod 302-2, and the outer sleeve of the slide rod 302-2 is connected with a spring 302-3, and the two ends of the spring 302-3 are fixedly connected to the sleeve 302-1 and the slide rod 302-2 respectively. The other end of the sleeve 302-1 is connected to the pressure relief pipe 302-4, and the two pressure relief pipes 302-4 are connected to the sealing ring 302-5. The pressure relief pipe 302-4 passes through the connecting flange 104 and is connected to the sealing ring 302-5. The sealing ring 302-5 is fixedly connected to one side of the connecting flange 104, and the sleeve 302-1 is fixedly connected to one side of the fixed plate 301. By setting the sealing ring 302-5, the sealing effect between the connecting flange 104 and the interface method is ensured to avoid liquid leakage.

[0061] It is worth emphasizing that the extrusion assembly 303 includes an extrusion block 303-1, and a placement groove 303-4 is opened in the extrusion block 303-1. The upper part of the inner wall of the placement groove 303-4 is fixedly connected to a multi-section telescopic sleeve 303-2. The bottom end of the multi-section telescopic sleeve 303-2 is fixedly connected to the upper part of the connecting plate 303-3. One side of the extrusion block 303-1 is fixedly connected to the side corresponding to the anti-sliding block 303-5. The upper part of the multi-section telescopic sleeve 303-2 is connected to the telescopic tube 305. The telescopic tube 305 is located in the placement groove 303-4. By setting the sealing assembly 205, when the piston disc 205-1 moves to the left, The gas in the sealing tube 201 will be squeezed into the conduit 207. When it moves to the right, the sealing plate 205-7 is pushed by the pressure and flipped along the rotating rod 205-4. When the piston disc 205-1 moves to the left again, the sealing plate 205-7 will drive the connecting sleeve 205-5 to flip downward under the action of the elastic force of the coil spring 205-6, thereby sealing the through hole 205-2 again. By arranging the sealing plate 205-7, the coil spring 205-6 and the rotating rod 205-4 on the surface of the piston disc 205-1, the sealing effect of the piston disc 205-1 is guaranteed, while ensuring that external gas can continue to enter the sealing tube 201.

[0062] In addition, the reinforcement component 304 includes a reinforcement block 304-1, and a mounting groove 304-3 is provided above the reinforcement block 304-1. The lower part of the inner wall of the mounting groove 304-3 is fixedly connected to the bottom end of the elastic telescopic rod 304-2. The lower part of the reinforcement block 304-1 is an arc surface, and the side of the reinforcement block 304-1 close to the connecting flange 104 is provided with a slope 304-4. The top of the elastic telescopic rod 304-2 is fixedly connected to the lower part of the connecting plate 303-3. Since the reinforcement component 304 is composed of several reinforcement blocks 304-1, the reinforcement block 304-1 will continue to press down after contacting the interface pipe, causing the elastic telescopic rod 304-2 to contract, thereby ensuring that multiple reinforcement blocks 304-1 all contact and fit the interface pipe, thereby improving the initial fixing effect of the water meter on the interface pipe and avoiding the displacement of the interface pipe.

[0063] Working principle: When in use, the water meter needs to be placed at the interface to be connected. Since the tee pipe 101 and the connection plate all adopt the maximum diameter standard, if the diameter of the interface is consistent with the tee pipe 101, it needs to be installed through the flange. If the diameter of the interface is smaller than the water meter, the interface needs to be plugged into the tee pipe 101 for installation;

[0064] When the diameter of the interface is consistent with the diameter of the tee pipe 101, the flange at the interface needs to be docked with the connecting flange 104, and then the connecting flange 104 and the flange are fixed by bolts. During the installation process, the flange of the interface will first contact the extrusion block 303-1 and the anti-sliding block 303-5, and push the extrusion block 303-1 and the anti-sliding block 303-5 to move backward. At this time, the sliding rod 302-2 will squeeze the gas in the sliding sleeve 302-1 into the pressure relief pipe 302-4, and the telescopic pipe 305 will move along with the extrusion block 303-1. 03-1 gradually contracts due to the movement of the sleeve 302-1. When the gas enters the pressure relief pipe 302-4 through the sliding sleeve 302-1, the pressure relief pipe 302-4 will transport the gas to the sealing ring 302-5 on the side of the connecting flange 104, causing the sealing ring 302-5 to be in an expanded state at this time. When the connecting flange 104 is fitted with the flange at the interface, the sealing ring 302-5 is squeezed and quickly fills the gap between the connecting flange 104 and the flange at the interface. The spring 302-3 is squeezed and pushes the extrusion block 303-1.

[0065] When the diameter of the interface is smaller than that of the tee pipe 101, a stainless steel gasket needs to be placed outside the interface, and then the interface is inserted into the tee pipe 101. By rotating the handle 209 in the opposite direction, the handle 209 drives the adjusting rod 204-1 to rotate during the rotation. Since the surface of the adjusting rod 204-1 is provided with an arc-shaped limit groove 204-2, and the piston disc 205-1 is slidably connected in the limit groove 204-2 through the limit block 205-8, as the adjusting rod 204-1 rotates, the piston disc 205-1 will move back and forth left and right. When the piston disc 205-1 moves to the left, the gas in the sealing tube 201 is squeezed into the conduit 207. When it moves to the right, the sealing plate 205-7 is pushed by the pressure and flipped, allowing outside air to enter the sealing disc. This reciprocating process will continuously inject gas into the conduit 207. When the gas enters the conduit 207 and enters along the sleeve 208-1 respectively When the telescopic tube 305 and the connecting tube 208-2 are in contact, the expansion block 208-3 will expand due to the entry of gas, and the gas entering the multi-section telescopic sleeve 303-2 through the telescopic tube 305 will push and squeeze the multi-section telescopic rod 206 to extend. At this time, the connecting plate 303-3 moves downward, so that the several reinforcement blocks 304-1 connected to the bottom of the connecting plate 303-3 squeeze the pipe of the interface. Since multiple reinforcement blocks 304-1 squeeze the interface pipe at the same time, it ensures that when the water meter is connected to an interface with a diameter smaller than the tee pipe 101, on the one hand, the interface pipe can be fixed by multiple reinforcement blocks 304-1, and the stainless steel gasket can be squeezed to preliminarily seal one side of the tee pipe 101. On the other hand, the volume of the expansion block can be increased by inflating multiple expansion blocks 208-3, so that the gap between the interface, the stainless steel gasket and the tee pipe 101 can be filled through the expansion block 208-3.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
