According to the scheme, a signal transmission channel is established in the mode that air in water is discharged through a cavity object, so that signals are stably transmitted out.

Description

Technical Field

[0001] The utility model belongs to the technical field of instruments, and in particular relates to an instrument and an intelligent instrument system used in an environment prone to being soaked in water. Background Art

[0002] The installation environment of smart meters is relatively harsh, especially the outdoor installation environment. When the rainy season comes, smart meters and other equipment are often soaked in water for a long time. Once soaked in water, the signal will be attenuated or retransmitted. It may even cause the signal of the smart meter to be unable to transmit normally due to severe soaking in water, increasing the power loss of the smart meter and the maintenance and after-sales costs.

[0003] In the prior art, there are two main methods to solve this problem. One is to use an external extension antenna. The use of an external extension antenna is to extend the original antenna sealed inside the smart meter to above the water level through the external extension antenna. However, the threading holes of the external extension antenna need to be reserved in advance during the structural design, which increases the uncertainty of the sealing and adds additional costs. The external extension antenna also increases the complexity of packaging. In addition to this method, when the smart meter is soaked in water, the signal will be attenuated or retransmitted. It may even be that the signal of the smart meter cannot be transmitted normally due to severe soaking in water, which increases the power loss of the smart meter. Manual regular inspection and drainage are required, which greatly increases the labor cost and increases the insecurity of personnel during the drainage process. Utility Model Content

[0004] To solve the above problems, the utility model provides an instrument for use in an environment prone to water immersion, wherein a water retaining member is provided on the meter head for preventing water from contacting the meter head when immersed in water so as to form a cavity above the meter head for transmitting instrument signals.

[0005] On the basis of the above solution, the water retaining member includes a connecting joint for sealingly connecting with the meter head housing and a signal transmission cavity for forming a cavity above the meter head.

[0006] Based on the above scheme, the connecting joint shown includes a vertical fixed wall for wrapping around the side wall of the meter head and a planar fixed wall for abutting against the top wall of the meter head, and the planar fixed wall is provided with a sealing groove ring for installing a sealing ring to prevent water from entering the cavity formed by the signal transmission cavity from the gap between the vertical fixed wall and the meter head.

[0007] On the basis of the above scheme, there are two sealing groove rings, which are adjacent to each other; when the water retaining member is fixedly connected to the meter head, the sealing rings installed in the two sealing groove rings are pressed against each other.

[0008] Based on the above solution, the shape of the cavity formed by the signal transmission cavity is cylindrical or trumpet-shaped.

[0009] Based on the above solution, the minimum cross-sectional diameter of the cavity formed by the signal transmission cavity is 25mm-100mm.

[0010] On the basis of the above solution, the signal transmission cavity of the water retaining member extends circumferentially at one end away from the connecting joint to form a support plate for contacting with the manhole cover of the instrument installation well.

[0011] The present application also provides an intelligent instrument system for use in an environment prone to water immersion, comprising an intelligent instrument for collecting fluid information, a water retaining member arranged on the meter head of the intelligent instrument for preventing water from contacting the meter head when immersed in water so as to form a cavity above the meter head for transmitting instrument signals, a collector for wireless signal communication with the intelligent instrument, and a remote management platform connected to the collector via wired or wireless signals; the water retaining member uses the water retaining member in the above-mentioned instrument.

[0012] Based on the above-mentioned instrument system, the present application also provides a signal transmission method for a smart meter under water conditions, wherein a water stop is provided on the meter head for preventing water from contacting the meter head under water conditions to form a cavity above the meter head for instrument signal transmission; when the instrument requires signal transmission, the signal passes through the cavity formed by the outer shell of the smart meter head and the water stop and is transmitted between the meter and the collector, and the collector is connected to the remote management platform via a wired or wireless signal; the water stop uses the water stop in the above-mentioned instrument.

[0013] Combined with the above background of signal attenuation or retransmission of existing outdoor smart meter equipment immersed in water, and aimed at the increase in power loss of smart meters and other equipment due to long-term immersion in water, this application proposes a meter for use in an environment prone to water immersion. The main principle of this meter is to use air as the medium for signal transmission. In the dry season, when the smart meter is not immersed in water, it is deployed in advance to ensure that there is spare air medium, so that the smart meter can establish a stable connection channel with the collector and ensure stable transmission. This solution mainly uses the method of hollow objects to displace the air in the water, establish a channel for signal transmission, and transmit the signal stably.

[0014] The utility model of the intelligent instrument system and signal transmission method for water-prone environments can effectively prevent the intelligent instrument and other devices from being set up with long-bubble water, causing the signal to attenuate or retransmit, and even prevent the signal of the intelligent instrument from being unable to be transmitted normally due to severe water immersion, thereby increasing the power loss of the intelligent instrument. The instrument of the present application has the advantages of being simple and reliable, low cost, controllable price, easy to operate, and easy to market, and can be used for the stable transmission of signals of intelligent instruments immersed in water in outdoor environments.

[0021] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1 As shown, the present application provides an instrument for use in an environment prone to being immersed in water, wherein a water retaining member 1 is provided on a meter head 2 of the instrument for preventing water from contacting the meter head 2 when immersed in water so as to form a cavity above the meter head 2 for transmitting instrument signals.

[0024] The above-mentioned instrument refers to an intelligent instrument that uses wireless transmission to transmit signals. The installation environment of the instrument is relatively harsh, especially the outdoor instrument well. When the rainy season comes, the intelligent instrument and other equipment are often soaked in water for a long time. Once soaked in water, the signal will be attenuated or retransmitted. It may even happen that the signal of the intelligent instrument cannot be transmitted normally due to severe soaking in water, which increases the power loss of the intelligent instrument and increases the maintenance and after-sales costs. In order to solve this technical problem, the above-mentioned instrument of the present application can form a cavity above the meter head 2 of the instrument through the water retaining member 1. Even if the instrument is soaked in water, there is no water in the cavity, so it does not affect the signal transmission of the instrument.

[0025] Figure 1 The instrument in the figure only shows the meter header part, and other parts of the instrument are no longer shown in this embodiment. That is to say, the water retaining member 1 in this embodiment can be applied to all existing instruments. It is only necessary to change the shape of the water retaining member 1 according to the different shapes of the meter header 2. The purpose is to form a cavity for instrument signal transmission above the meter header 2 through the water retaining member 1.

[0026] like Figure 2 As shown, the water retaining member 1 includes a connecting joint 1 - 1 for sealingly connecting to the housing of the meter head 2 and a signal transmission cavity 1 - 2 for forming a cavity above the meter head 2 .

[0027] There are many ways to connect the connector 1 - 1 to the meter head 2 . No matter which one is used, at least the top surface of the meter head 2 needs to be exposed in the signal transmission cavity 1 - 2 .

[0028] like Figure 3 As shown, the connecting joint 1-1 includes a vertical fixed wall 1-11 for wrapping around the side wall of the meter head 2 and a planar fixed wall 1-12 for abutting against the top wall of the meter head 2, and the planar fixed wall 1-12 is provided with a sealing groove ring 1-121 for preventing water from entering the cavity formed by the signal transmission cavity 1-2 through the gap between the vertical fixed wall 1-11 and the meter head 2, and a sealing ring is installed therein.

[0029] In order to form a good sealing effect between the meter head 2 and the cavity formed by the signal transmission cavity 1-2, there are two sealing groove rings 1-121, and the two sealing groove rings 1-121 are adjacent to each other. When the water retaining member 1 is fixedly connected to the meter head 2, the sealing rings installed in the two sealing groove rings 1-121 squeeze each other. This method can effectively improve the sealing between the meter head 2 and the water retaining member 1.

[0030] There are two purposes for setting the plane fixed wall 1-12. One is to make the connection between the water retaining part 1 and the meter head 2 more secure. After the connecting joint 1-1 is installed on the meter head 2, the top wall of the meter head 2 will abut against the plane fixed wall 1-12, and the two will form a certain contact surface. The other is to better prevent water from entering the cavity formed by the signal transmission cavity 1-2. If only a sealing ring for water retaining is added to the vertical fixed wall 1-11, it is difficult for the sealing ring to form a good sealing effect due to the gap between the vertical fixed wall 1-11 and the side wall of the meter head 2. By adding a sealing groove ring 1-121 and installing a sealing ring on the plane fixed wall 1-12, the water retaining effect of the sealing ring can be fully exerted when the water retaining part 1 and the meter head 2 are axially fixed.

[0031] In order to facilitate the connection joint 1-1 of the water retaining member 1 to be better sealed with the outer shell of the meter head 2, the shape of the connection joint 1-1 is adapted to the shape of the meter head 2, that is: if the shape of the meter head 2 is cylindrical, then the shape of the connection joint 1-1 also forms a cylindrical cavity that fits the cylindrical meter head 2; if the shape of the meter head 2 is square, then the shape of the connection joint 1-1 forms a square cavity that fits the square meter head 2.

[0032] Figure 1 The meter head 2 in the figure is a cylindrical meter head 2. At this time, the vertical fixed wall 1-11 of the matching connecting joint 1-1 is also cylindrical. When in use, the cylindrical meter head 2 is directly inserted into the cylindrical connecting joint 1-1. The sealing ring in the sealing groove ring 1-121 arranged on the plane fixed wall 1-12 will prevent water from entering the cavity formed by the signal transmission cavity 1-2 from the gap between the vertical fixed wall 1-11 and the meter head 2.

[0033] In order to enhance the firmness of the connection between the meter head 2 and the water retaining member 1, a snap, lock, or threaded connection may be used between the connecting joint 1-1 and the meter head 2 to further fix the two (this fixation is axial fixation between the water retaining member 1 and the meter head 2).

[0034] The signal transmission cavity 1-2 forms a cavity for signal transmission above the meter head 2. In order to better transmit the signal, the shape of the cavity formed by the signal transmission cavity 1-2 is cylindrical or trumpet-shaped (the cross-section of the trumpet-shaped cavity on the side close to the meter head 2 is smaller than the cross-section on the side away from the meter head 2).

[0035] The diameter of the cavity formed by the signal transmission cavity 1-2 affects the effect of signal transmission. In the case of being soaked in water, the larger the diameter of the cavity formed by the signal transmission cavity 1-2 of the water retaining member 1, the smaller the effect on signal transmission.

[0036] This application uses a URT water meter produced by Qingdao HiWeiZi Instrument Co., Ltd. for simulation to test the influence of cavities of different diameters formed by the signal transmission cavity 1-2 on the signal strength under different water immersion depths. The test results are shown in Table 1.

[0037] Table 1 Effect of different diameters of cavities formed by the signal transmission cavity on signal strength

[0038]

[0039] / Indicates that the water retaining member 1 is not used.

[0040] It can be seen from the above table that when the instrument is immersed in water to a depth of 30cm, the instrument signal can no longer be transmitted to the water surface. Therefore, the signal transmission cavity 1-2 formed by the water retaining member 1 is used for signal transmission to re-establish the signal transmission channel. It can also be seen from the table that the diameter of the signal transmission cavity 1-2 formed by the water retaining member 1 affects the effect of signal transmission. The larger the diameter, the better the signal transmission effect (the maximum diameter tested in the experiment is 100mm. Exceeding this range has no obvious effect on the signal transmission effect, and a diameter that is too large is meaningless in practical applications)

[0041] Based on the above test, as a preferred embodiment, the diameter of the cavity formed by the signal transmission cavity 1-2 of the water retaining member 1 is 25mm-100mm.

[0042] During the rainy season, the instrument installation well may be completely soaked in water. Therefore, the height of the water retaining member 1 should be as consistent as possible with the depth of the instrument installation well. For this purpose, the signal transmission cavity 1-2 of the water retaining member 1 extends circumferentially at one end away from the connection joint 1-1 to form a support plate 1-3 for contacting the well cover of the instrument installation well. In this way, when the well cover is closed, the well cover forms a downward pressure on the water retaining member 1. The purpose of setting the support plate 1-3 is to increase the contact area between the well cover of the instrument installation well and the water retaining member 1, so that the connection between the water retaining member 1 and the meter head 2 is more secure. This method also performs axial fixation between the water retaining member 1 and the meter head 2.

[0043] Example 2

[0044] Based on the instrument in Example 1, Figure 5 As shown, the present application also provides an intelligent instrument system for use in an environment prone to water immersion, including an intelligent instrument for collecting fluid information, a water retaining member 1 arranged on a meter head 2 of the intelligent instrument for preventing water from contacting the meter head 2 under water conditions to form a cavity above the meter head 2 for instrument signal transmission, a collector 3 for wireless signal communication with the intelligent instrument, and a remote management platform 4 connected to the collector 3 via wired or wireless signals; the water retaining member 1 uses the water retaining member in the instrument of Example 1.

[0045] like Figure 4 As shown, in the prior art, when the meter is soaked in water, the signal will be attenuated or retransmitted, and even the signal of the smart meter cannot be transmitted normally due to severe soaking in water, which increases the power loss of the smart meter and the maintenance and after-sales costs. In order to solve this technical problem, the above-mentioned meter of the present application can form a cavity above the meter head 2 through the water retaining member 1. Even if the meter is soaked in water, there is no water in the cavity, so it does not affect the signal transmission of the meter.

[0046] Example 3

[0047] Based on the instrument of Example 1 and the system of Example 2, the present application provides a signal transmission method for a smart meter under water conditions, wherein a water retaining member 1 is provided on the meter head 2 for preventing water from contacting the meter head 2 under water conditions to form a cavity above the meter head 2 for instrument signal transmission; when the instrument requires signal transmission, the signal passes through the housing of the smart meter head 2 and the cavity formed by the water retaining member and is transmitted between the meter and the collector 3, and the collector 3 is connected to the remote management platform 4 via a wired or wireless signal; the water retaining member 1 uses the water retaining member in the instrument of Example 1.

[0048] Each embodiment in this specification is described in a related manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. The above description is only a preferred embodiment of the utility model, and is not intended to limit the scope of protection of the utility model.
