Description

Technical Field

[0001] This utility model relates to the field of water meter data acquisition technology, specifically a water meter data acquisition device based on Bluetooth technology. Background Technology

[0002] Bluetooth technology, as a short-range wireless communication technology, is widely used in Internet of Things (IoT) scenarios due to its low power consumption, low cost, and ease of deployment. The core of a Bluetooth-based water meter data collector is to establish communication with the water meter terminal (such as a smart water meter) through a Bluetooth module, enabling real-time collection, transmission, and management of water consumption data.

[0003] Currently, existing data acquisition devices are usually powered by batteries, which need to be replaced after a period of use. Most data acquisition devices are installed and fixed to the pipes in the water meter well by screws or even expansion bolts, which makes the battery replacement process complicated and reduces the efficiency of battery replacement. Utility Model Content

[0004] The purpose of this invention is to provide a water meter data collector based on Bluetooth technology to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water meter data collector based on Bluetooth technology, comprising: a collector body; a mounting base fixedly disposed on the collector body, the mounting base being located on the back of the collector body; a mounting head inserted into the mounting base; two square through holes symmetrically arranged on the mounting head; a limiting block slidably disposed within the square through holes, the limiting block moving axially along the square through holes; a rotating rod rotatably disposed within the mounting head, the rotating rod being located between the two limiting blocks; an elliptical block fixedly disposed on the rotating rod, the surface of the elliptical block abutting against the surfaces of the two limiting blocks; and a limiting groove disposed within the mounting base, wherein when the rotating rod is rotated, the elliptical block pushes the two limiting blocks to move, causing the limiting blocks to enter the limiting groove.

[0006] Preferably, it further includes: a polygonal docking post, fixedly disposed at one end of the rotating rod; a sliding sleeve, slidably disposed on the outer surface of the polygonal docking post; and a fixed seat, fixedly disposed on the mounting head, wherein the axes of the polygonal docking post and the fixed seat are located on the same straight line; the position of the rotating rod is fixed when the sliding sleeve is inserted into the fixed seat.

[0007] Preferably, it further includes: a plurality of positioning rods fixedly disposed inside the mounting head, wherein the inside of the limiting block is slidably disposed with respect to the outer surface of the positioning rods; a plurality of return springs sleeved on the positioning rods, wherein the two ends of the return springs respectively abut against the surface of the limiting block and the inner surface of the mounting head, and wherein the return springs deform when the limiting block is moved.

[0008] Preferably, it further includes: a support block, fixedly disposed at the mating end of the mounting head; and a support groove, formed inside the mounting base, wherein when the mounting head is configured to mate with the mounting base, the support block is inserted into the support groove.

[0009] Preferably, it further includes: a reinforcing rib, which is fixedly disposed on the mounting base, and the surface of the reinforcing rib is fixedly connected to the surface of the collector body.

[0010] Preferably, it further includes: a pipe clamp, fixedly disposed on the mounting head, for fixing the mounting head to the pipe.

[0011] Preferably, it further includes: a blocking block, fixedly disposed at one end of the polygonal docking post, the blocking block limiting the movement range of the sliding sleeve.

[0012] This utility model provides a water meter data collector based on Bluetooth technology, which has the following advantages:

[0013] (1) This utility model rotates the rotating rod so that the elliptical block follows the rotation. During the rotation of the elliptical block, the two limiting blocks are pushed open so that the limiting blocks extend out of the square through hole and enter the limiting groove, thereby achieving quick fixation of the collector body. When disassembly is required, the rotating rod can be rotated in the opposite direction. The structure is simple, the disassembly and installation speed is fast, and the battery replacement efficiency of the collector body is improved.

[0014] (2) This utility model inserts the sliding sleeve into the fixed seat along the polygonal docking post, so that the polygonal docking post is limited. The limitation of the polygonal docking post prevents the rotating rod from rotating, which effectively ensures the stable support of the elliptical block and improves the fixing strength.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: Referring to 1-3, in this embodiment, a water meter data collector based on Bluetooth technology includes: a collector body 1; a mounting base 2, fixedly disposed on the collector body 1, the mounting base 2 being located on the back of the collector body 1; a mounting head 3, inserted into the mounting base 2; two square through holes 4, symmetrically arranged, extending through the mounting head 3; a limiting block 5, slidably disposed inside the square through holes 4, the limiting block 5 moving axially along the square through holes 4; a rotating rod 6, rotatably disposed inside the mounting head 3, the rotating rod 6 being located between the two limiting blocks 5; and an elliptical block. 7. The elliptical block 7 is fixedly mounted on the rotating rod 6, and its surface is in contact with the surfaces of the two limiting blocks 5. The limiting groove 10 is opened inside the mounting base 2. When the rotating rod 6 is rotated, the elliptical block 7 pushes the two limiting blocks 5 to move, so that the limiting blocks 5 enter the limiting groove 10. The mounting base 2 can be used to connect and fix the collector body 1 to the pipeline through cooperation with the mounting head 3. The limiting blocks 5 can be used to stably connect and fix the collector body 1 through cooperation with the limiting groove 10. The elliptical block 7 can be used to open up the limiting blocks 5.

[0021] It also includes: a polygonal docking post 11, fixedly mounted on one end of the rotating rod 6; a sliding sleeve 12, slidably mounted on the outer surface of the polygonal docking post 11; and a fixed base 13, fixedly mounted on the mounting head 3. The axes of the polygonal docking post 11 and the fixed base 13 are located on the same straight line. When the sliding sleeve 12 is inserted into the fixed base 13, the position of the rotating rod 6 is fixed, which can fix the rotating rod 6 and ensure the stable connection of the collector body 1.

[0022] It also includes: several positioning rods 8, fixedly installed inside the mounting head 3, with the inner surface of the limiting block 5 slidingly disposed with respect to the outer surface of the positioning rods 8; several return springs 9, sleeved on the positioning rods 8, with both ends of the return springs 9 abutting against the surface of the limiting block 5 and the inner surface of the mounting head 3 respectively. When the limiting block 5 is set to move, the return springs 9 deform. By setting the positioning rods 8, the limiting block 5 can be positioned and guided, so that it is not easy for it to tilt during the process of being opened by the elliptical block 7, so that the limiting block 5 can stably enter the limiting groove 10.

[0023] It also includes: a support block 14, which is fixedly installed at the docking end of the mounting head 3; and a support groove 15, which is opened inside the mounting base 2. When the mounting head 3 is configured to dock with the mounting base 2, the support block 14 and the support groove 15 are inserted into each other, which can position the mounting head 3 and the mounting base 2, so that the limiting block 5 and the limiting groove 10 can be stably aligned, and at the same time improve the support force between the two.

[0024] It also includes: a reinforcing rib 17, which is fixedly installed on the mounting base 2. The surface of the reinforcing rib 17 is fixedly connected to the surface of the collector body 1. By setting the reinforcing rib 17, the overall structural strength can be improved.

[0025] It also includes: a pipe clamp 16, which is fixedly mounted on the mounting head 3 and used to fix the mounting head 3 to the pipe.

[0026] It also includes: a blocking block 18, which is fixedly installed at one end of the polygonal docking post 11. The blocking block 18 restricts the movement range of the sliding sleeve 12 and prevents the sliding sleeve 12 from falling off the polygonal docking post 11.

[0027] This utility model provides a water meter data collector based on Bluetooth technology, and its working principle is as follows:

[0028] When the battery on the collector body 1 needs to be replaced, the staff will pull the sliding sleeve 12 out of the fixed seat 13 to release the restriction on the rotating rod 6. Then, the sliding sleeve 12 will be rotated to drive the elliptical block 7 to rotate. Under the action of the reset spring 9, the limit block 5 will be pushed to reset and separate from the limit groove 10, releasing the restriction between the mounting seat 2 and the mounting head 3. After that, the staff can directly remove the collector body 1 from the pipe to replace the battery.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
