Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic water meter technology, and in particular relates to an antifreeze ultrasonic water meter. Background Technology

[0002] An ultrasonic water meter is a new type of water meter that detects the time difference caused by the change in speed of an ultrasonic beam as it propagates upstream and downstream in water, analyzes and processes the data to obtain the water flow rate, and then calculates the water flow rate.

[0003] For example, Chinese patent CN223500458U discloses an antifreeze ultrasonic water meter, including an ultrasonic water meter with a casing fixed to it. Inside the casing, multiple No. 2 and No. 3 insulation cotton blocks are inserted, wrapping the outer surface of the ultrasonic water meter. A sealing cap is connected to the top of the casing. By configuring the casing, sealing cap, No. 1 fixing plate, No. 2 fixing plate, limiting rod, guide slide rod, moving plate, insertion rod, pushing spring, and connecting plate, the antifreeze device on the ultrasonic water meter is easily disassembled. By squeezing the connecting plates on both sides of the sealing cap, the casing can be separated from the sealing cap, exposing the internal ultrasonic water meter display, facilitating counting and inspection by staff and improving practicality.

[0004] The aforementioned patent has the following problems: Since the unlocking method requires the operator to pinch the connecting plates on both sides of the sealing cap with both hands to separate the outer casing from the sealing cap, this unlocking method relies on the operator simultaneously pinching the connecting plates with both hands. Sufficient force must be applied by both hands synchronously to complete the unlocking process. If the operator operates with only one hand, lacks sufficient hand strength, or applies force asynchronously with both hands, it will result in failure to unlock successfully.

[0005] In view of this, we propose an antifreeze ultrasonic water meter. Utility Model Content

[0006] The purpose of this invention is to provide an antifreeze ultrasonic water meter to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides an antifreeze ultrasonic water meter, including an ultrasonic water meter and a housing covering the surface of the ultrasonic water meter, and also including four limiting blocks. A heat insulation cotton layer is provided inside the housing. An observation port for observing the ultrasonic water meter dial is provided on the top of the housing. Four limiting grooves are provided equidistantly in a ring inside the observation port. A sealing cover for sealing the observation port is provided on the top of the housing. A fixing groove is provided on each of the four sides of the sealing cover. The four limiting blocks are slidably disposed in the four fixing grooves respectively. Each of the four fixing grooves is provided with a moving component that drives the corresponding limiting block to move to the outside of the corresponding fixing groove. A driving component is provided inside the sealing cover that enables the four moving components to move synchronously back and forth along the fixing grooves.

[0008] In this technical solution, when it is necessary to seal the observation port of the housing with the sealing cover, the operator places the sealing cover into the observation port. At this time, the four limiting grooves coincide with the four fixed grooves. The operator then uses the drive component to move the four moving components along the fixed grooves, and pushes a portion of the four limiting blocks into the overlapping limiting grooves, thus sealing the observation port with the sealing cover. The contact area between the sealing cover and the observation port is provided with heat insulation cotton. When it is necessary to open the sealing cover to observe the dial of the ultrasonic water meter through the observation port, the operator uses the drive component to move the four limiting blocks from the limiting grooves into the overlapping fixed grooves. At this time, the sealing cover is no longer connected to the housing, achieving simultaneous unlocking. The operator then removes the sealing cover and observes the dial of the ultrasonic water meter through the observation port.

[0009] In the above technical solution, the drive assembly further includes a fixing hole, a fixing tube, a turntable, and a torsion spring. The fixing hole is opened on the top of the sealing cover and communicates with four fixing slots. The fixing tube is located inside the fixing hole and is rotatably connected to the fixing hole. The other end of the fixing tube extends to the outside of the fixing hole. The turntable is fixedly connected to the end of the fixing tube located outside the fixing hole. The torsion spring is located inside the fixing tube. One end of the torsion spring is fixedly connected to the fixing hole, and the other end of the torsion spring is fixedly connected to the bottom of the turntable.

[0010] In this technical solution, the operator rotates the turntable in the forward direction, which drives the fixed tube to rotate. At this time, the torsion spring is deformed. When the turntable stops rotating, the torsion spring drives the turntable and the fixed tube to rotate in the reverse direction.

[0011] In the above technical solution, the drive assembly further includes four baffles and four arc-shaped grooves. The four arc-shaped grooves are equidistantly arranged in a ring on the surface of the fixed tube, and the four baffles are equidistantly fixedly installed in a ring on the surface of the fixed tube. The four baffles are located on one side of the four arc-shaped grooves respectively.

[0012] In this technical solution, a fixed tube drives four baffles to rotate synchronously.

[0013] In the above technical solution, further, each of the four sets of moving components includes a fixed plate, a connecting rod, and an arc-shaped block. The fixed plate is fixed in the fixed groove, one end of the connecting rod is fixedly connected to the corresponding limiting block, the other end of the connecting rod passes through the fixed plate and slides with the fixed plate, and the arc-shaped block is fixedly connected to the other end of the connecting rod.

[0014] In this technical solution, when the arc-shaped block moves into the limiting groove, it drives the connecting rod and the moving plate to move. The connecting rod drives the limiting block to move. When the arc-shaped block moves into the arc-shaped groove, the moving plate rebounds through the spring. The moving plate drives the connecting rod to move. The connecting rod drives the lower limiting block to move, so that the limiting block enters the limiting groove from the fixed groove.

[0015] In the above technical solution, the four sets of moving components further include a moving plate and a spring. The moving plate is fixedly sleeved on the connecting rod and slides in cooperation with the corresponding fixing groove. The spring is fixedly sleeved on the connecting rod, with one end of the spring fixedly connected to the fixing plate and the other end of the spring fixedly connected to the moving plate.

[0016] In this technical solution, when the arc-shaped block moves into the limiting groove, it compresses the spring through the moving plate. When the arc-shaped block moves into the arc-shaped groove, the moving plate rebounds through the spring.

[0017] In the above technical solution, the turntable and the fixed tube are further connected by bolts.

[0018] In this technical solution, the turntable and the fixed tube are connected by bolts, which facilitates the inspection of the torsion spring inside the fixed tube.

[0019] Furthermore, in the above technical solution, a handle is provided on the sealing cover.

[0020] In this technical solution, the handle makes it easier to remove the sealing cap from the observation port.

[0021] The beneficial effects of this utility model are:

[0022] By rotating the turntable forward, the turntable drives the fixed tube to rotate, causing the torsion spring to deform. The fixed tube then drives the four baffles to rotate. When the four arc-shaped blocks rotate to their corresponding arc-shaped grooves, one side of each block abuts against a baffle and cannot rotate. The spring force of the four springs pushes the corresponding moving plates, which in turn drive the connecting rods to move towards the fixed tube. The connecting rods then drive the four arc-shaped blocks and the four limiting blocks to move, causing the arc surfaces of the four arc-shaped blocks to enter the four arc-shaped grooves. The four limiting blocks then move from their limiting grooves into the overlapping fixed grooves, thus preventing the sealing cover from connecting to the housing. This allows for one-button unlocking without the need for simultaneous application of force by both hands, making operation simpler and avoiding unlocking failures caused by uneven force or single-handed operation. This significantly improves the reliability and convenience of unlocking, allowing operators to unlock with one hand. Attached Figure Description

[0032] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0033] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0034] Example 1: This example provides an antifreeze ultrasonic water meter 1, including an ultrasonic water meter 1 and a housing 2 covering the surface of the ultrasonic water meter 1, and also includes four limiting blocks 3. A heat insulation cotton layer 4 is provided inside the housing 2. An observation port 5 is provided on the top of the housing 2 for observing the dial of the ultrasonic water meter 1. Four limiting grooves 6 are provided in a ring at equal intervals inside the observation port 5. A sealing cover 7 is provided on the top of the housing 2 to seal the observation port 5. A fixing groove 8 is provided on all four sides of the sealing cover 7. The four limiting blocks 3 are respectively slidably disposed in the four fixing grooves 8. Each of the four fixing grooves 8 is provided with a moving component 9 that drives the corresponding limiting block 3 to move to the outside of the corresponding fixing groove 8. A driving component 10 is provided inside the sealing cover 7 to make the four sets of moving components 9 move synchronously back and forth along the fixing grooves 8.

[0035] The housing 2 includes an upper housing and a lower housing, which wrap around the surface of the ultrasonic water meter 1 and are connected by bolts. The insulation layer 4 inside the housing 2 provides insulation and freeze protection for the ultrasonic water meter 1. The limiting grooves 6 cooperate with the limiting blocks 3. When the observation port 5 of the housing 2 needs to be sealed by the sealing cover 7, the operator places the sealing cover 7 into the observation port 5. At this time, the four limiting grooves 6 coincide with the four fixed grooves 8. The operator then uses the drive assembly 10 to drive the four moving components 9 along the fixed grooves. The groove 8 moves, and through the four moving components 9, a portion of the four limiting blocks 3 is pushed into the overlapping limiting groove 6, thereby sealing the observation port 5 with the sealing cover 7. The contact area between the sealing cover 7 and the observation port 5 is provided with heat insulation cotton. When it is necessary to open the sealing cover 7 to observe the dial of the ultrasonic water meter 1 through the observation port 5, the operator uses the driving component 10 to make the four limiting blocks 3 move from the limiting groove 6 into the overlapping fixed groove 8. At this time, the sealing cover 7 is no longer connected to the housing 2, and can be unlocked at the same time. At this time, the operator removes the sealing cover 7 and looks at the dial of the ultrasonic water meter 1 through the observation port 5.

[0036] Examples 2-5: This example provides an antifreeze ultrasonic water meter 1. In addition to the technical solutions of the above examples, the drive assembly 10 includes a fixing hole 1001, a fixing tube 1002, a turntable 1003, and a torsion spring 1004. The fixing hole 1001 is located on the top of the sealing cover 7 and communicates with four fixing grooves 8. The fixing tube 1002 is located inside the fixing hole 1001 and is rotatably connected to it. The other end of the fixing tube 1002 extends to the outside of the fixing hole 1001. The turntable 1003 is fixedly connected to one end of the fixing tube 1002 located outside the fixing hole 1001. The torsion spring 1004 is located inside the fixing tube 1002. One end of the torsion spring 1004 is fixedly connected to the fixing hole 1001, and the other end is fixedly connected to the bottom of the turntable 1003. The drive assembly 10 also includes four baffles 1005 and four arc-shaped grooves 1006. The four arc-shaped grooves 1006 are... Four baffles 1005 are equidistantly arranged in a ring on the surface of the fixed tube 1002. The four baffles 1005 are respectively located on one side of the four arc-shaped grooves 1006. Each of the four sets of moving components 9 includes a fixed plate 901, a connecting rod 902, and an arc-shaped block 903. The fixed plate 901 is fixed in the fixed groove 8. One end of the connecting rod 902 is fixedly connected to the corresponding limiting block 3. The other end of the connecting rod 902 passes through the fixed plate 901 and slides with the fixed plate 901. The arc-shaped block 903 is fixedly connected to the other end of the connecting rod 902. The four sets of moving components 9 also include a moving plate 904 and a spring 905. The moving plate 904 is fixedly sleeved on the connecting rod 902 and slides with the corresponding fixed groove 8. The spring 905 is fixedly sleeved on the connecting rod 902. One end of the spring 905 is fixedly connected to the fixed plate 901, and the other end of the spring 905 is fixedly connected to the moving plate 904.

[0037] Among them, the contact surfaces of the four arc-shaped blocks 903 with the fixed tube 1002 are arc-shaped. When the observation port 5 needs to be sealed by the sealing cover 7, the elastic force of the four springs 905 causes the arc-shaped surfaces of the four arc-shaped blocks 903 to abut against the surface of the fixed tube 1002. Parts of the four limiting blocks 3 are located outside the corresponding fixed grooves 8. At this time, the operator rotates the turntable 1003, which drives the fixed tube 1002 to rotate. At this time, the torsion spring 1004 deforms, and the fixed tube 1002 drives the four baffles 1005 to rotate. When the four arc-shaped blocks 903 rotate to the corresponding arc-shaped grooves 1006, one side of the four arc-shaped blocks 903 is in contact with the baffle. When 1005 is in contact with the rotating plate, it cannot rotate. At this point, the elastic force of the four springs 905 pushes the corresponding moving plate 904. The four moving plates 904 respectively drive the connecting rod 902 to move towards the fixed tube 1002. The four connecting rods 902 respectively drive the four arc-shaped blocks 903 and the four limiting blocks 3 to move, so that the arc-shaped surfaces of the four arc-shaped blocks 903 respectively enter the four arc-shaped grooves 1006. At this time, the four limiting blocks 3 enter the limiting grooves 6. Then, the operator puts the sealing cover 7 into the observation port 5. The bottom of the sealing cover 7 contacts the dial of the ultrasonic water meter 1. At this time, the operator no longer rotates the rotating plate 1003. The spring force of spring 1004 is greater than the spring force of the four springs 905. At this time, the torsion spring 1004 rebounds, driving the turntable 1003 to rotate in the opposite direction. The turntable 1003 drives the fixed tube 1002 to rotate, and the fixed tube 1002 drives the four baffles 1005 to rotate. At this time, the arc surfaces of the four arc grooves 1006 press against the arc surfaces of the four arc blocks 903 respectively. The four arc blocks 903 are pressed and move towards the limiting groove 6. The movement of the four arc blocks 903 drives the four connecting rods 902 to move. The four connecting rods 902 drive the corresponding moving plate 904 and the limiting block 3 to move, and through the four moving plates 904... When the four springs 905 are compressed, and the arc surfaces of the four arc blocks 903 are no longer in the arc grooves 1006 and are in contact with the surface of the fixed tube 1002, a portion of the four limiting blocks 3 enters the overlapping limiting grooves 6 from the four fixed grooves 8 respectively. At this time, the sealing cover 7 seals the observation port 5. When it is necessary to remove the sealing cover 7 from the observation port 5, the operator rotates the turntable 1003 forward so that the arc surfaces of the four arc blocks 903 enter the corresponding arc grooves 1006, and the four limiting blocks 3 enter the overlapping fixed grooves 8 from the limiting grooves 6 respectively. At this time, the sealing cover 7 is no longer fixed on the housing 2, and the operator removes the sealing cover 7 from the observation port 5.

[0038] Example 6: This example provides an antifreeze ultrasonic water meter 1, which, in addition to the technical solutions of the above examples, has a turntable 1003 and a fixed tube 1002 connected by bolts.

[0039] The turntable 1003 and the fixed tube 1002 are connected by bolts, which facilitates the inspection of the torsion spring 1004 inside the fixed tube 1002.

[0040] Example 7: This example provides an antifreeze ultrasonic water meter 1, which, in addition to the technical solutions of the above examples, has a handle 11 on the sealing cover 7.

[0041] The handle 11 makes it easier to remove the sealing cap 7 from the observation port 5.

[0042] Working principle: When the observation port 5 needs to be sealed by the sealing cover 7, the elastic force of the four springs 905 causes the arc surfaces of the four arc-shaped blocks 903 to abut against the surface of the fixed tube 1002. Parts of the four limiting blocks 3 are located outside the corresponding fixed grooves 8. At this time, the operator rotates the turntable 1003, which drives the fixed tube 1002 to rotate. At this time, the torsion spring 1004 deforms, and the fixed tube 1002 drives the four baffles 1005 to rotate. When the four arc-shaped blocks 903 rotate to the corresponding arc-shaped grooves 1006, one side of the four arc-shaped blocks 903 abuts against the baffle 1005 and cannot rotate. At this time, the flow is interrupted. The elastic force of the four springs 905 pushes the corresponding moving plates 904. The four moving plates 904 respectively drive the connecting rods 902 to move towards the fixed tube 1002. The four connecting rods 902 respectively drive the four arc-shaped blocks 903 and the four limiting blocks 3 to move, so that the arc-shaped surfaces of the four arc-shaped blocks 903 enter the four arc-shaped grooves 1006 respectively. At this time, the four limiting blocks 3 enter the limiting grooves 6. At this time, the operator puts the sealing cover 7 into the observation port 5. The bottom of the sealing cover 7 contacts the dial of the ultrasonic water meter 1. At this time, the operator no longer rotates the turntable 1003. The elastic force of the torsion spring 1004 is greater than that of the torsion spring 1004. The elastic force of the four springs 905 causes the torsion spring 1004 to rebound, driving the turntable 1003 to rotate in the opposite direction. The turntable 1003 drives the fixed tube 1002 to rotate, which in turn drives the four baffles 1005 to rotate. At this time, the arc surfaces of the four arc grooves 1006 press against the arc surfaces of the four arc blocks 903. The four arc blocks 903 are pressed and move towards the limiting groove 6. The movement of the four arc blocks 903 also drives the four connecting rods 902 to move. The four connecting rods 902 drive the corresponding moving plates 904 and limiting blocks 3 to move, and through the four moving plates 904, they also control the four springs. When the four arc-shaped blocks 903 are not in the arc-shaped groove 1006 and are in contact with the surface of the fixed tube 1002, a portion of the four limiting blocks 3 enters the overlapping limiting groove 6 from the four fixed grooves 8 respectively. At this time, the sealing cover 7 seals the observation port 5. When it is necessary to remove the sealing cover 7 from the observation port 5, the operator rotates the turntable 1003 in the forward direction so that the arc-shaped surfaces of the four arc-shaped blocks 903 enter the corresponding arc-shaped grooves 1006, and the four limiting blocks 3 enter the overlapping fixed grooves 8 from the limiting grooves 6 respectively. At this time, the sealing cover 7 is no longer fixed on the housing 2. The operator then removes the sealing cover 7 from the observation port 5.
