TECHNICAL FIELD

[0002] In recent years, the domestic internet of things develops rapidly, and intelligent water meters have been installed in large quantities. At present, there are various ways for water meter flow collection. The commonly used way is to realize water meter reading collection by counting the number of rotations of the meter pointer. The specific implementation is to install a magnetic pointer in the meter and place a Hall sampling module above the corresponding position outside the meter. However, the sampling module of this sampling method needs to be placed vertically above the pointer, which has a large shelter on the meter dial, making it difficult for subsequent manual inspection of the water meter. UTILITY MODEL CONTENTS

[0003] In order to overcome the shortcomings of the problems mentioned in the background art, the utility model provides a water meter data sampling device without shelter.

[0005] More preferably, it further comprises a pull bar; a first sliding groove is provided at the bottom of the bottom plate, and a second sliding groove is provided at the front side of the bottom plate; one end of the anisotropic magnetic sensing element is connected with the pull bar, and the other end of the pull bar passes through the first sliding groove, and the anisotropic magnetic sensing element slides in the first sliding groove.

[0006] More preferably, it further comprises a buckle; the inner side wall of the cover is connected with the buckle, and the buckle is detachably arranged, and the middle part of the connecting line passes through the buckle and is arranged for limiting the connecting line.

[0007] More preferably, the cover and the bottom plate are made of transparent plastic material.

[0008] The utility model has the advantages of:

[0009] 1. This utility model sets an anisotropic magnetic sensing element on the side wall of the groove and sets the pointer of the water meter dial to be made of magnetic material. When the pointer rotates, the change in magnetization direction will cause the resistance to change. At this time, the change in the direction and intensity of the magnetic field can be detected by measuring the change in resistance, thereby accurately measuring the rotation data of the pointer and collecting it. Furthermore, the anisotropic magnetic sensing element can sense the direction of the change in the magnetic field, so it does not need to be set vertically above the pointer, thus not obstructing the water meter dial and facilitating the subsequent manual self-inspection of the water meter dial pointer data.

[0010] 2. This utility model uses a lever to move the anisotropic magnetic sensing element to slide in the first groove, thereby fine-tuning the position of the anisotropic magnetic sensing element so that the anisotropic magnetic sensing element can always be close to the pointer whose position changes due to different water meter specifications, thus avoiding the problem of it being unable to get close to the pointer for accurate measurement.

[0011] 3. This utility model restricts the connecting wires by using clips, causing the connecting wires to be biased towards the inner wall of the housing, thereby avoiding the connecting wires from obstructing the view during manual self-inspection. In addition, the circuit board can be made of a flexible material to fit the inner wall of the housing, thereby further biasing the connecting wires towards the inner wall of the housing. The detachable clips also allow for flexible adjustment of the placement of internal components. Attached Figure Description

Detailed Implementation

[0016] The present application will now be described more fully hereinafter with reference to the accompanying drawings, in which currently preferred embodiments of the application are shown. The application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of thorough and complete disclosure of the application and are fully presented for illustrative purposes with the scope of the application being defined by the appended claims. Embodiments

[0017] A non-shielded water meter data sampling device, as shown in Figs. 1-3 The shell 1 is detachably connected with the bottom plate 2 at the bottom, and the bottom plate 2 is provided with a connecting end 2001 at the front side. The water meter 3 is arranged below the bottom plate 2, and the bottom plate 2 is connected with the water meter 3 through the connecting end 2001 and bolts.

[0018] The device further comprises connecting columns 101, a circuit board 102, an anisotropic magnetic sensing element 103, and connecting wires 105. The bottom plate 2 is provided with a plurality of connecting columns 101. The plurality of connecting columns 101 are jointly connected with the circuit board 102. The bottom plate 2 is provided with a groove 2002 at the bottom, and the sidewall of the groove 2002 is connected with the anisotropic magnetic sensing element 103. One end of the anisotropic magnetic sensing element 103 is connected with the connecting wires 105, and the other end of the connecting wires 105 is connected with the circuit board 102.

[0019] The device further comprises a push bar 104. The bottom plate 2 is provided with a first sliding groove 2003 at the bottom, and a second sliding groove 2004 is arranged at the front side of the bottom plate 2. One end of the anisotropic magnetic sensing element 103 is connected with the push bar 104, and the other end of the push bar 104 passes through the first sliding groove 2004. The anisotropic magnetic sensing element 103 slides in the first sliding groove 2003.

[0020] Referring to Fig. 3 The device further comprises a buckle 106. The buckle 106 is arranged on the inner sidewall of the shell 1 and is detachably arranged. The middle part of the connecting wires 105 passes through the buckle 106, so that the connecting wires 105 as a whole deviate towards the inner sidewall of the shell 1.

[0021] The shell 1 and the bottom plate 2 are both made of transparent plastic material.

[0022] The application is implemented as follows:

[0023] Firstly, the bottom plate 2 is connected with the water meter 3 through bolts, and the groove 2002 is aligned with the dial of the water meter 3, so that the installation is completed. In the prior art, the number of rotations of the pointer on the dial is recorded by using the Hall element to sense the magnetic field, and the reading of the water meter 3 is collected. However, the Hall element can only sense the vertical magnetic field, so the Hall element needs to be arranged directly above the pointer, thereby forming unavoidable shielding above the pointer, which makes it difficult for the subsequent manual inspection to check the data of the dial pointer of the water meter 3. By arranging the anisotropic magnetic sensing element 103 on the side wall of the groove 2002, the anisotropic magnetic sensing element 103 senses the change of the magnetic field direction of the pointer on the dial of the water meter 3 when the pointer rotates, so as to realize the data sampling of the water meter 3 without shielding. Specifically, the pointer is made of magnetic material, and when the pointer rotates, the change of the magnetization direction will cause the resistance to change. At this time, the change of the direction and strength of the magnetic field can be detected by measuring the change of the resistance, so as to accurately measure the rotation data of the pointer and complete the reading collection of the water meter 3. Furthermore, since the anisotropic magnetic sensing element 103 can sense the change direction of the magnetic field, it does not need to be arranged vertically above the pointer, so as to avoid shielding the dial of the water meter 3, and facilitate the subsequent manual self-checking of the dial pointer data of the water meter 3.

[0024] Further, after the installation of the cover 1, the bottom plate 2 and the water meter 3 is completed, the position of the pointer on the dial of the water meter 3 is different due to different specifications, and the anisotropic magnetic sensing element 103 cannot be adjusted in position accordingly, so that the anisotropic magnetic sensing element 103 is far away from the position of the pointer, causing inaccurate measurement. However, separate element placement design for different specifications of the water meter 3 will increase the cost. Therefore, the first sliding groove 2003 is arranged at the bottom of the bottom plate 2, and the second sliding groove 2004 is arranged at the front side of the bottom of the bottom plate 2, so that after the installation is completed, the anisotropic magnetic sensing element 103 can still be driven to slide in the first sliding groove 2003 by the knob 104, so as to finely adjust the position of the anisotropic magnetic sensing element 103, so that the anisotropic magnetic sensing element 103 can always approach the pointer whose position changes due to different specifications of the water meter 3, thereby avoiding the problem that the anisotropic magnetic sensing element 103 cannot approach the pointer for accurate measurement.

[0025] Further, the anisotropic magnetic sensing element 103 and the circuit board 102 need to be provided with a connecting line 105, and the anisotropic magnetic sensing element 103 is located on the side wall of the recess 2002, and when subsequent manual self-checking is performed, the reading of the dial 3 will be read through the shell 1 and the recess 2002 and recorded, and the anisotropic magnetic sensing element 103 will not block the line of sight during manual self-checking, and the placement of the connecting line 105 will cause a certain line of sight obstruction, so that the detachable buckle 106 is arranged on the inner side wall of the shell 1, and the connecting line 105 is limited by the buckle 106, so that the connecting line 105 is deviated to the inner side wall of the shell 1 as a whole, thereby avoiding the line of sight obstruction caused by the connecting line 105 during manual self-checking, and the circuit board 102 can be made of flexible material and attached to the inner side wall of the shell 1, thereby further deviating the connecting line 105 to the inner side wall of the shell 1, and cooperating with the detachable buckle 106 to flexibly adjust the placement position of the internal element, and further, the shell 1 and the bottom plate 2 are both made of transparent plastic material, which is convenient for manual self-checking to collect the reading of the water meter 3 dial.

[0026] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range of those skilled in the art without departing from the purpose of the utility model.
