Description

Technical Field

[0001] The utility model relates to the technical field of spare parts of remote transmission meters, in particular to a signal transmitting coil compatible with various water meter movements. Background Art

[0002] The general base of a water meter includes a metering mechanism accommodating cavity, a metering mechanism, a watch glass and a middle cover. The metering mechanism is installed in the metering mechanism accommodating cavity, the watch glass is installed above the metering mechanism, the glass is installed above the dial, and the middle cover covers the outside of the watch glass and is fixed to the core accommodating cavity.

[0003] In order to reduce the working intensity during the reading of civilian water meters, signal transmitting water meters have emerged. The signal transmitting water meter can input the flow signal into the remote system for centralized counting and management. Its working principle is to generate a signal by the induction of a magnetic sensitive element and a magnetic steel block, and this signal is output by the pulse signal output circuit of the magnetic sensitive element.

[0004] Currently, the remote transmission water meters in use on the market include a meter housing, a movement, a glass, a meter cover and a shell. The movement includes a signal transmitting needle and is arranged in the meter housing. The glass covers the meter housing. The meter cover is screwed onto the meter housing to press the glass and the meter housing tightly. The shell covers the meter cover and is connected to the meter housing. An induction element is arranged in the shell, and the induction element is inductively connected to the signal transmitting needle. The induction element collects the rotation information of the signal transmitting needle. When the signal transmitting pointer rotates, the signal transmitting pointer acts on the signal collecting sensor, and then the signal collecting sensor sends a sampling electrical signal to the control circuit board, thereby realizing intelligent counting.

[0005] Example of the prior art 1, referring to the patent document CN209280051U, discloses a remote transmission water meter, including a meter housing, a movement arranged in the meter housing, a glass covering the meter housing, and a meter cover screwed to the meter housing and used for pressing the glass and the meter housing tightly. The movement includes a signal transmitting needle. A signal transmitting coil is also arranged between the glass and the meter housing. The signal transmitting coil is provided with a receiving cavity, and an induction element and a circuit board are arranged in the receiving cavity. The induction element is electrically connected to the circuit board, and the induction element is inductively connected to the signal transmitting needle. The signal transmitting coil is clamped between the glass and the meter housing, and there is no need to additionally provide a shell, making the overall structure simple. In the installation of the signal transmitting coil in Example 1, through the cooperation of the holes and positioning pins opened on the side shell and the side of the movement, an installation relationship with a unique installation angle is realized.

[0006] Example of the prior art 2. Referring to the patent document CN211477268U, a positioning mechanism for installing an additional device of an intelligent water meter is disclosed, which includes a general base meter and an additional device box body. The general base meter includes a middle cover and a meter glass. The middle cover is provided with a circular window hole, and further includes an upper positioning gear disk and a lower positioning gear disk. The lower positioning gear disk is fixed between the middle cover and the meter glass. The lower positioning gear disk is provided with an annular rack I located in the end face. The upper positioning gear disk is fixed to the additional device box body, and the upper positioning gear disk is provided with an annular rack II meshing with the annular rack I. The utility model can provide a positioning reference for installing an external additional device box body on the general base meter, reduce product costs and improve production and assembly efficiency. In Example 2, the installation of the signal coil is realized through the meshing of the upper positioning gear disk and the lower positioning gear disk. And it can be seen from the drawings that the annular racks I are distributed at intervals of 90 degrees, so 4 groups of installation relationships at intervals of 90 degrees are realized.

[0007] In summary, in the prior art, the relative installation position of the signal coil and the meter movement is limited. The most direct impact is that the positions of the signal pointers in different meter movements are different. Therefore, the distances between the signal induction mechanisms in the signal coil and the signal pointers are long or short, resulting in low monitoring accuracy of the signal pointer operation and unstable signal reception and transmission. On the other hand, due to fewer or only one installation angle, the existing signal coils are only suitable for specific specifications of meter movements, and the versatility is poor. In addition, in Example 2, the tooth mating relationship is vertical, and the installation direction of the signal coil and the meter movement is also vertical. This method is prone to bumping into the tooth structure during disassembly and assembly, resulting in damage to the tooth surface; second, there is a lack of a horizontal connection and positioning structure, resulting in poor connection strength and stability after assembly, and it is easy to loosen and misalign after being stressed. Summary of the Invention

[0008] In order to overcome the above deficiencies of the prior art, the present invention provides a signal coil compatible with multiple water meter movements.

[0009] The technical solution for the present invention to solve its technical problems is: A signal coil compatible with multiple water meter movements, including:

[0010] A signal coil body, which is annular. The outer side wall of the lower end of the signal coil body has a first annular tooth pattern, and the inner side wall of the signal coil body has an installation chamber;

[0011] A positioning and mating member, which is configured in the water meter movement and has a second annular tooth pattern. The second annular tooth pattern can be meshed with the first annular tooth pattern after rotating at any angle, so that the positioning and mating member and the signal coil body achieve pre-positioning and mating;

[0012] A signal induction mechanism, which is configured in the installation chamber;

[0013] The positioning posts are formed on the outer sidewall of the signal - sending coil body. There are multiple positioning posts and they are irregularly distributed. Each positioning post is provided with a vertical positioning hole, and any one or more vertical positioning holes are connected to fasteners, thereby fixing the signal - sending coil body to the water meter movement.

[0014] Specifically, each of the positioning posts has one or more vertical positioning holes.

[0015] In some preferred embodiments of the present utility model, the installation chamber has an upper opening, and a closed cover plate is arranged at the upper opening;

[0016] The closed cover plate is convexly provided with a first connection block downward. A first connection hole is opened on the sidewall of the installation chamber. The first connection block can be inserted into the first connection hole so that the closed cover plate and the installation chamber form a detachable connection fit.

[0017] In some preferred embodiments of the present utility model, a second connection block is convexly arranged in the installation chamber. A second connection hole is opened on the signal - sending induction mechanism. The second connection block can be inserted into the second connection hole so that the signal - sending induction mechanism and the installation chamber form a detachable connection fit.

[0018] Furthermore, a notch groove is opened on the upper edge of the signal - sending coil body. The installation chamber extends from the inner side to the outer side of the signal - sending coil body through the notch groove and forms an outward - protruding part, and one or more through - holes are opened on the outward - protruding part.

[0019] More specifically, when the closed cover plate is covered on the installation chamber, the closed cover plate fills the notch groove.

[0020] In some preferred embodiments of the present utility model, several levels of positioning steps are arranged on the inner wall of the signal - sending coil body. The multiple positioning steps are arranged in sequence from top to bottom, and the inner diameter of the upper - level positioning step is larger than that of the lower - level positioning step.

[0021] In some preferred embodiments of the present utility model, gaskets are arranged in the vertical positioning holes.

[0022] In some preferred embodiments of the present utility model, one or more columns of deformation grooves are opened on the inner wall of the vertical positioning hole.

[0023] The beneficial effects of the present utility model are as follows:

[0024] First, the tooth - pattern structures (the first annular gear and the second annular tooth pattern) are annularly arranged. Therefore, the first annular gear and the second annular tooth pattern can be rotated by any angle and then re - meshed, so that the signal - sending coil can be adjusted to the optimal position and distance relative to different water meter movements, ensuring the monitoring and communication between the signal - sending induction mechanism and the signal pointer.

[0025] Second, for different water meter movement mechanisms, different positioning posts can be selected for cooperation to meet fixed requirements (that is, it is not necessarily required to insert fasteners into the vertical positioning holes of all positioning posts each time, specifically depending on the requirements of the current water meter movement mechanism), so as to be compatible with multiple movement types and have higher applicability.

[0026] Third, during assembly, a dual cooperation structure of pre-positioning cooperation and fastening cooperation is adopted, which effectively improves the assembly production efficiency of the water meter. The pre-positioning is carried out horizontally, and the fastening is carried out vertically, realizing a two-way connection method, making the connection more stable and reliable, and greatly reducing the situation of loosening during use.

[0040] Embodiment 1

[0041] Referring to Figures 1 to 9 , a signal - sending coil compatible with multiple water - meter movement mechanisms includes:

[0042] A signal - sending coil body 1, which is annular. There is a first annular tooth pattern 11 on the outer side wall of the lower end of the signal - sending coil body 1, and an installation chamber 12 on the inner side wall of the signal - sending coil body 1;

[0043] A positioning and mating member 2, which is configured in the water - meter movement mechanism 3 and has a second annular tooth pattern 21. The second annular tooth pattern 21 can be meshed with the first annular tooth pattern 11 after rotating at any angle, so that the positioning and mating member 2 and the signal - sending coil body 1 achieve pre - positioning and mating;

[0044] A signal - sending and sensing mechanism 4, which is configured in the installation chamber 12; specifically, the signal - sending and sensing mechanism 4 mainly includes a circuit board and sensing components (such as Hall sensors, reed switches, magnetoresistors, magnetodiodes, etc.) for sampling the operating conditions of the signal - sampling pointer 31;

[0045] The positioning posts 13 are formed on the outer side wall of the signal transmitting coil body 1. There are multiple positioning posts 13 and they are irregularly distributed. Each positioning post 13 is provided with a vertical positioning hole 131. Any one or more vertical positioning holes 131 are inserted with fasteners 6 (such as screws and other components), so as to fix the signal transmitting coil body 1 to the water meter movement 3.

[0046] The above content is the basic structural scheme of the present utility model. During installation, first, through the engagement of the first positioning tooth pattern and the second annular tooth pattern 21, the pre-positioning and mating relationship between the positioning and mating member 2 and the signal transmitting coil body 1 is realized. Then, the fastener 6 is inserted into the vertical positioning hole 131 of the corresponding positioning post 13, and at the same time, the fastener 6 also needs to be inserted into the hole position on the water meter movement 3 to fix the signal transmitting coil body 1 to the water meter movement 3.

[0047] It should be particularly noted that the differences from the prior art are at least as follows. First, the tooth pattern structure (the first annular gear and the second annular tooth pattern 21) is annularly arranged. Refer to Figure 2 、 Figure 3 , so the first annular gear and the second annular tooth pattern 21 can be rotated by any angle and then re-engaged, so that the signal transmitting coil can be adjusted to the best position and distance relative to different water meter movements 3, ensuring the monitoring and communication between the signal transmitting and sensing mechanism 4 and the signal pointer 31. Second, for different water meter movements 3, in order to meet the fixing requirements, different positioning posts 13 can be used for matching (that is, it is not necessarily required to insert fasteners 6 into the vertical positioning holes 131 of all positioning posts 13 each time, which is specifically determined according to the requirements of the current water meter movement 3), so as to be compatible with multiple movement types and have higher applicability. Third, during assembly, a double-mating structure of pre-positioning and mating and fastening is adopted, effectively improving the assembly production efficiency of the water meter. The pre-positioning is carried out horizontally and the fastening is carried out vertically, realizing a two-way connection method, making the connection more stable and reliable, and greatly reducing the situation of loosening during use.

[0048] Specifically, refer to Figure 1 、 Figure 9 , each of the positioning posts 13 has one or more vertical positioning holes 131. When there is only one vertical positioning hole 131 in a single positioning post 13, if this positioning post 13 is to be used in combination with the fastener 6, there is no need to make a selection, and the fastener 6 is directly screwed into the vertical positioning hole 131 of the corresponding positioning post 13. When there are multiple vertical positioning holes 131 in a single positioning post 13, one or more fasteners 6 are selectively screwed into one or more vertical positioning holes 131 of the corresponding positioning post 13 according to the structural requirements of the current water meter movement 3.

[0049] Example, refer to Figure 1 、 Figure 9, the uniquely existing vertical positioning hole 131 in the single positioning post 13 is defined as the first positioning hole, and the two vertical positioning holes 131 in the single positioning post 13 are defined as the second positioning hole and the third positioning hole. When assembling the signal - sending coil with the water - meter movement 3, the selectable combinations of positioning holes are as follows: First, only use one of the first positioning hole, the second positioning hole, and the third positioning hole. In this case, 3 connection methods are formed; Second, use two of the first positioning hole, the second positioning hole, and the third positioning hole. In this case, 3 connection methods are formed; Third, use all three of the first positioning hole, the second positioning hole, and the third positioning hole. In this case, 1 connection method is formed. In summary, the signal - sending coil in this example can at least be compatible with the installation requirements of 7 types of water - meter movements 3. It should be noted that when there are more positioning posts 13 and vertical positioning holes 131, the signal - sending coil of the present utility model will be able to be compatible with a greater number of water - meter movements 3.

[0050] In some embodiments of the present utility model, referring to Figure 7 , the installation chamber 12 has an upper - end opening 121, and a closed cover plate 122 is arranged at the upper - end opening 121. Preferably, the closed cover plate 122 protrudes downward with a first connection block 1221, a first connection hole 123 is opened on the side wall of the installation chamber 12, and the first connection block 1221 can be inserted into the first connection hole 123 so that the closed cover plate 122 and the installation chamber 12 form a detachable connection fit. When it is necessary to disassemble, assemble, or repair the signal - sending induction mechanism 4, the closed cover plate 122 is removed from the upper - end opening 121, and the installation chamber 12 can be opened. At this time, the signal - sending induction mechanism 4 can be operated, which is very convenient. After the repair or assembly is completed, through the cooperation of the first connection block 1221 and the first connection hole 123, the closed cover plate 122 is reassembled to cover the upper - end opening 121 to provide protection for the signal - sending induction mechanism 4 in the installation chamber 12.

[0051] Furthermore, referring to Figure 3 , a second connection block 124 protrudes inside the installation chamber 12, a second connection hole 41 is opened on the signal - sending induction mechanism 4, and the second connection block 124 can be inserted into the second connection hole 41 so that the signal - sending induction mechanism 4 and the installation chamber 12 form a detachable connection fit. Through the arrangement of the second connection block 124 and the second connection hole 41, on the one hand, during connection, it can play a good limiting role on the signal - sending induction mechanism 4, making it installed in place and not likely to move during use; on the other hand, it adopts a flexible connection, so when disassembly is required, the operation is very convenient and the signal - sending induction mechanism 4 will not be damaged.

[0052] Preferably, referring to Figure 8, a plurality of positioning steps 14 are provided on the inner wall of the signal transmitting ring body 1. The multiple positioning steps 14 are arranged in sequence from top to bottom, and the inner diameter of the upper positioning step 14 is larger than that of the lower positioning step 14. Through the arrangement of the multiple positioning steps 14, a good positioning effect can be achieved, improving the installation and matching accuracy between the signal transmitting ring body 1, the water meter movement 3, and the intelligent water meter housing; at the same time, it can also play a role in blocking water, preventing the water leakage at the water meter movement 3 from climbing upwards.

[0053] A more preferably structural solution for the positioning hole is as follows: First, a gasket 5 is provided in the vertical positioning hole 131. One is to play a sealing role to prevent impurities from entering the vertical positioning hole 131 to corrode the fastener 6; the second is to play a shock-absorbing role, making the connection effect of the fastener 6 more stable and reliable; the third is to evenly distribute the pressure, making the acting force between the fastener 6 and the positioning post 13 more balanced, and preventing the positioning post 13 from being locally deformed or damaged.

[0054] Since water meters are generally installed outdoors and need to cope with relatively complex environments, after long-term use, the fastener 6 is prone to rust, and then the fastener 6 is too tightly fitted with the vertical positioning hole 131, resulting in difficulty in smooth disassembly in the later stage. To eliminate the above defects, in some preferred embodiments of the present invention, refer to Figure 8 , a row or multiple rows of deformation grooves 1311 are opened on the inner wall of the vertical positioning hole 131. The deformation grooves 1311 communicate with the vertical positioning hole 131. Thus, when the fastener 6 is disassembled, under the action of pressure, the vertical positioning hole 131 will also undergo a certain deformation, and the rust slag of the fastener 6 can enter the deformation grooves 1311 to prevent the fastener 6 from being too tightly fitted with the vertical positioning hole 131, so that the rusty fastener 6 can also be easily disassembled.

[0055] Embodiment 2

[0056] Refer to Figure 1 , Figure 3 , in this embodiment, a notch groove 15 is opened on the upper edge of the signal transmitting ring body 1. The installation chamber 12 extends from the inner side to the outer side of the signal transmitting ring body 1 through the notch groove 15 to form an outer convex portion 125, and one or more through holes 1251 are opened on the outer convex portion 125. The setting of the through holes 1251 can make the installation chamber 12 communicate with the outside of the signal transmitting ring. First, it can improve the heat dissipation efficiency, reduce the temperature in the installation chamber 12, make the signal transmitting and sensing mechanism 4 work in a lower temperature environment to ensure stable operation; second, since the through holes 1251 are provided at the outer convex portion 125, they will not communicate with the inner side of the signal transmitting ring body 1, eliminating the risk of water leakage at the water meter movement 3 entering the installation chamber 12; third, it breaks the relatively airtight space environment, making the communication ability of the signal transmitting ring more stable.

[0057] More specifically, when the closed cover plate 122 is covered on the installation chamber 12, the closed cover plate 122 fills the notch groove 15, which is more reasonable in spatial design and makes the appearance more integral and unobtrusive.

[0058] It should be noted that other technical solutions of the present invention belong to the prior art, so they will not be elaborated here.

[0059] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as within the protection scope of the present invention.
