Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of magnetic float level gauges, specifically relating to an installation bracket and a magnetic float level gauge. Background Technology
[0002] With the widespread application of magnetic float level gauges in high-temperature environments (such as petrochemical and energy sectors), the ambient temperature requirements have increased from the conventional range to ultra-high temperatures of 300℃ or even 350℃. The rated operating temperature of traditional level gauges for remote transmission is typically ≤120℃ (this 120℃ usually refers to the rated operating temperature of the precision sensing unit inside the connecting rod in the remote transmission process). To adapt to this demand, the industry's technological approach has evolved as follows:
[0003] 1. Initial fixing method: The level gauge is directly fixed to the outer wall of the measuring cylinder with clamps. Heat is directly conducted through the metal, which causes the level gauge to overheat and fail.
[0004] 2. Improved fixing method: Increase the distance between the level gauge remote transmission and the measuring cylinder by installing the panel, and reduce heat conduction by using air convection;
[0005] 3. Current fixing method: Add heat insulation material (such as ceramic fiber, aerogel) and mounting bracket between the level gauge remote transmission and the measuring cylinder to form a physical thermal barrier layer, reducing the contact temperature from 300℃ to below 120℃.
[0006] Although the current fixing method can support 300℃ conditions, it still has significant drawbacks in ultra-high temperature environments of 350℃: multi-layer structure assembly is cumbersome and costly, high-temperature carbonization of insulation materials leads to moisture-proof failure, moisture intrusion greatly reduces insulation performance, and it cannot effectively reduce 350℃ to the safe threshold in the long term.
[0007] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a mounting bracket and a magnetic float level gauge.
[0008] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0066] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.
[0067] The technical solution of this utility model will now be described with reference to the accompanying drawings.
[0068] Example 1:
[0069] Reference Figure 1 , Figure 2 As shown, the mounting bracket 1 in this embodiment may include: a main body 11, a first mounting part 12, and a second mounting part 13. The first mounting part 12 is connected to a first end of the main body 11; the second mounting part 13 is connected to a second end of the main body 11, and the first mounting part 12 and the second mounting part 13 are respectively disposed on opposite sides of the main body 11. In the thickness direction of the main body 11, the distance between the first mounting part 12 and the main body 11 is less than or equal to the distance between the first mounting part 12 and the second mounting part 13. Specifically, the distance L1 between the first mounting part 12 and the main body 11 is greater than 0, and the distance L2 between the first mounting part 12 and the second mounting part 13 is greater than 0, where L1 ≤ L2. Compared to the L1 = L2 configuration, when L1 < L2, the side of the mounting bracket 1 can be stepped, facilitating gradient heat dissipation during heat transfer. Figures 4-7As shown, when the connecting rod 3 with remote transmission is installed on the measuring cylinder 2 using the new mounting bracket 1, after the temperature-sensing liquid flows into the measuring cylinder 2, the temperature is sequentially conducted from the measuring cylinder 2 to the first mounting part 12, the main body 11, the second mounting part 13, and the connecting rod 3 of the mounting bracket 1. During the heat transfer process, the temperature gradient can be reduced by the stepped mounting bracket 1, so that the temperature transmitted to the connecting rod 3 is controlled within the rated operating temperature range of the precision sensing unit in the connecting rod 3. The mounting bracket 1 in this application has a simple and stable structure, low cost, convenient installation, good heat dissipation effect, and good industrial application value.
[0070] Preferably, refer to Figure 1 As shown, the main body 11 of this application has several through holes 110. This design increases the thermal resistance of the mounting bracket 1 and reduces the heat conduction rate. For example, compared to a design with elongated holes in the main body 11, this embodiment has three through holes 110 spaced apart along its length. This design provides greater structural strength and also increases the difficulty of transferring heat from the measuring cylinder 2 to the connecting rod 3. Of course, this application is not limited to this; other embodiments may have one, two, or four through holes 110 on the main body 11.
[0071] It should be noted that, according to the principle of heat conduction (Fourier's law of heat conduction), when the measuring cylinder 2 and the connecting rod 3 are connected by the mounting bracket 1, after the hot liquid flows into the measuring cylinder 2, the heat will be conducted to the connecting rod 3 through the mounting bracket 1. Since the main body 11 has a through hole 110, the cross-sectional area of the main body 11 becomes smaller at the through hole 110. Reducing the cross-sectional area (i.e., the cross-sectional area of the heat conduction path) of the main body 11 in the mounting bracket 1 will produce the following effect:
[0072] 1. Decreased thermal conductivity:
[0073] Since the rate of heat conduction (the amount of heat conducted per unit time, denoted as Q) is directly proportional to the thermally conductive area A, the formula for the rate of heat conduction is:
[0074]
[0075] in:
[0076] k is the thermal conductivity of the mounting bracket 1, which is a fixed value and depends on the material used in the mounting bracket 1; A is the cross-sectional area of the main body 11; ∆T is the temperature difference between the measuring cylinder 2 and the connecting rod 3; L is the length of the mounting bracket 1.
[0077] When the cross-sectional area A of the main body 11 of the mounting bracket 1 is reduced, the heat conduction rate Q will decrease accordingly. Therefore, under the same temperature difference ∆T, the amount of heat conducted to the connecting rod 3 will decrease, thus slowing down the rate at which the connecting rod 3 receives heat and causing a decrease in the rate of temperature rise of the connecting rod 3, thereby avoiding the risk of overheating of the precision sensing unit inside the connecting rod 3.
[0078] 2. Increased thermal resistance
[0079] Due to the thermal resistance (R) of the mounting bracket 1 used for heat conduction th The formula for ) is:
[0080]
[0081] Where k is the thermal conductivity of the mounting bracket 1, which is a fixed value and is related to the material used in the mounting bracket 1; A is the cross-sectional area of the main body 11; and L is the length of the mounting bracket 1.
[0082] Since the thermal resistance R remains constant under the premise that the length L of the mounting bracket 1 is constant. th It is inversely proportional to the cross-sectional area A. Therefore, when the cross-sectional area A of the main body 11 of the mounting bracket 1 decreases, the thermal resistance R will increase. th Heat is also more difficult to conduct from the measuring cylinder 2 to the connecting rod 3.
[0083] Since the mounting bracket 1 needs to be installed on the measuring cylinder 2 or the connecting rod 3 via a fastening structure (such as a clamp), in order to prevent the fastening structure from detaching from the first mounting part 12 and the second mounting part 13, thereby minimizing the separation of the mounting bracket 1 from the measuring cylinder 2 and the mounting bracket 1 from the connecting rod 3, refer to... Figure 1 As shown, in this embodiment, the first mounting part 12 has a first limiting groove 121 on both side walls, and the second mounting part 13 has a second limiting groove 131 on both side walls. When the fastening structure is installed on the mounting bracket 1, the fastening structure can be located in the first limiting groove 121 (second limiting groove 131). Of course, this application is not limited to this. In other embodiments, a first limiting groove 121 is provided on one side wall of the first mounting part 12; or, a second limiting groove 131 is provided on one side wall of the second mounting part 13; or, a first limiting groove 121 is provided on one side wall of the first mounting part 12 and a second limiting groove 131 is provided on one side wall of the second mounting part 13; or, only the first mounting part 12 is provided with the first limiting groove 121; or, only the second mounting part 13 is provided with the second limiting groove 131. All of the above solutions fall within the protection scope of this application. Based on this design, the possibility of separation of the mounting bracket 1 and the measuring cylinder 2 (separation of the mounting bracket 1 and the connecting rod 3) can be reduced to a certain extent, which is understandable and acceptable to those skilled in the art.
[0084] Optionally, to prevent the fastening structure from detaching from the mounting bracket 1, and to minimize the possibility of separation between the mounting bracket 1 and the measuring cylinder 2, or between the mounting bracket 1 and the connecting rod 3, refer to... Figure 1 As shown, in this embodiment, the end of the first mounting portion 12 away from the main body portion 11 is provided with a first limiting protrusion 122, and the end of the second mounting portion 13 away from the main body portion 11 is provided with a second limiting protrusion 132. The first limiting protrusion 122 and the second limiting protrusion 132 are bent toward the main body portion 11. Of course, this application is not limited to this. When only the end of the first mounting portion 12 away from the main body portion 11 is provided with the first limiting protrusion 122, the possibility of separation between the mounting bracket 1 and the measuring cylinder 2 can be minimized; or, when only the end of the second mounting portion 13 away from the main body portion 11 is provided with the second limiting protrusion 132, the possibility of separation between the mounting bracket 1 and the connecting rod 3 can be minimized. The above solutions all fall within the protection scope of this application, which is understandable and acceptable to those skilled in the art.
[0085] To ensure that L1 < L2, so as to facilitate gradient heat dissipation, refer to Figure 1 , Figure 2 As shown, in this embodiment, the first mounting part 12 is connected to the first end of the main body part 11 via the first connecting part 13, and the second mounting part 13 is connected to the second end of the main body part 11 via the second connecting part 14.
[0086] Preferably, to avoid stress concentration and affecting the structural strength of the mounting bracket 1, refer to Figure 1 , Figure 2 As shown, in this embodiment, the first mounting part 12 and the first connecting part 13, as well as the main body part 11 and the first connecting part 13, are connected by a rounded transition. The second mounting part 13 and the second connecting part 14, as well as the main body part 11 and the second connecting part 14, are also connected by a rounded transition.
[0087] Of course, this application is not limited to this. In other embodiments, only the first mounting part 12 is connected to the first end of the main body part 11 through the first connecting part 13, and the first mounting part 12 and the first connecting part 13 are connected by an arc transition (the main body part 11 and the first connecting part 13 are connected by an arc transition); or, only the second mounting part 13 is connected to the second end of the main body part 11 through the second connecting part 14, and the second mounting part 13 and the second connecting part 14 are connected by an arc transition (the main body part 11 and the second connecting part 14 are connected by an arc transition). All of these fall within the protection scope of this application, which is understandable and acceptable to those skilled in the art.
[0088] From the side view, refer to Figure 2As shown, the main body 11 in this application is flat and the mounting bracket 1 is arranged in a three-step shape. Therefore, the main body 11 in this embodiment includes a main body 111. When the heat on the measuring cylinder 2 is transferred to the connecting rod 3 through the mounting bracket 1, gradient heat dissipation can be formed at the mounting bracket 1.
[0089] Of course, this application is not limited to this; see also... Figure 3 As shown, in other embodiments, the main body 11 includes a plurality of main bodies 111, with adjacent main bodies 111 connected by a third connecting portion 112. In the thickness direction of the main body 11, at least one main body 111 has a gap with an adjacent main body 111. For example, in one embodiment, the main body 11 includes two main bodies 111, with two adjacent main bodies 111 connected by a third connecting portion 112. One main body 111 is connected to the first mounting portion 12 by a first connecting portion 13, and the other main body 111 is connected to the second mounting portion 13 by a second connecting portion 14. Therefore, the mounting bracket 1 has a four-step shape when viewed from the side. In another embodiment, when the first mounting portion 12 is connected to the first end of the main body 11 via the first connecting portion 13, and the second mounting portion 13 is connected to the second end of the main body 11 via the second connecting portion 14, and the main body 11 includes three main bodies 111 connected by a third connecting portion 112, the mounting bracket 1 has a five-step shape. When the mounting bracket 1 is in the shape of a six-step, seven-step, etc., the main body 11 of the mounting bracket 1 includes four main bodies 111, five main bodies 111, etc., which will not be described in detail here. According to this design, the main body 11 of the mounting bracket 1 can be seen as a multi-step shape from the side view. Compared with the design of the main body 11 being flat, when heat is transferred to the main body 11 in other embodiments, gradient heat dissipation can also be formed.
[0090] Example 2:
[0091] Reference Figures 4-7As shown, the magnetic float level gauge in this embodiment may include: a measuring cylinder 2, a mounting bracket 1 as described in Embodiment 1, a level gauge remote transmitter, and a junction box 4. The first mounting portion 12 of the mounting bracket 1 is fixedly mounted on the measuring cylinder 2; the level gauge remote transmitter includes a connecting rod 3, which is fixedly mounted on the second mounting portion 13 of the mounting bracket 1, with a gap between the connecting rod 3 and the measuring cylinder 2; the junction box 4 is fixedly mounted on the upper end of the connecting rod 3. When the connecting rod 3 with the remote transmitter is mounted on the measuring cylinder 2 using this novel mounting bracket 1, after the temperature-sensing liquid flows into the measuring cylinder 2, the temperature is sequentially conducted from the measuring cylinder 2 to the first mounting portion 12, the main body 11, the second mounting portion 13, and the connecting rod 3 of the mounting bracket 1. During the heat transfer process, the temperature gradient decreases through the stepped mounting bracket 1, ensuring that the temperature transmitted to the connecting rod 3 is controlled within the rated operating temperature range of the precision sensing unit within the connecting rod 3. The mounting bracket 1 in this application has a simple and stable structure, low cost, convenient installation, good heat dissipation effect, and good industrial application value. Meanwhile, by installing bracket 1, the connecting rod 3 and measuring cylinder 2 can be spaced apart, thereby reducing the impact of thermal radiation. Air can flow through the gap between the two, thereby carrying away heat and dissipating it, thus reducing heat transfer.
[0092] It should be noted that the magnetic level gauge in this embodiment typically includes a measuring cylinder, a magnetic level indicator, a magnetic float assembly, a remote level gauge transmitter, and a limit switch, among which the remote level gauge transmitter and limit switch are optional accessories. The core of this magnetic level gauge is the measuring cylinder 2, which is a vertically installed pressure chamber in direct contact with the liquid being measured. The magnetic float assembly is located inside the measuring cylinder 2 and rises and falls precisely with the liquid level. The magnetic level indicator is arranged along the length of the measuring cylinder 2 on its exterior. The magnetic field of the magnetic float assembly drives the corresponding magnetic level indicator to flip and change color (e.g., from white to red), thus providing a clear and intuitive visual indication of the liquid level at the equipment site. During the liquid level indication process, the measuring cylinder and the magnetic float assembly are in direct contact with the liquid being measured, while the tilting indicator and optional accessories (remote level gauge transmitter and limit switch) are not in direct contact with the liquid being measured, thus heat transfer occurs.
[0093] The connecting rod 3 is installed at intervals on the side of the measuring cylinder 2, using its internal precision sensing unit (reed switch, Hall element, etc.) to non-contactly detect the real-time position of the magnetic float's magnetic field. The junction box 4 contains a signal conversion module, which converts the position signal into a standardized industrial output signal (such as 4mA-20mA, HART protocol, etc.) to reliably transmit the liquid level data to the remote control system. The maximum heat resistance temperature of the precision sensing unit inside the connecting rod 3 generally does not exceed 120℃, and the operating ambient temperature of the signal conversion module inside the junction box 4 generally does not exceed 75℃. The stepped mounting bracket 1 achieves a decreasing temperature gradient, reducing the temperature of the connecting rod 3 and indirectly reducing the temperature transmitted to the junction box 4, ensuring the magnetic float level gauge can operate normally when measuring high-temperature media.
[0094] The mounting bracket 1 can be made of SUS304 stainless steel, which meets general corrosion resistance and strength requirements while also having a lower thermal conductivity than aluminum alloy. This means that, under stable heat source conditions, the SUS304 stainless steel mounting bracket 1 can transfer less heat. However, this application is not limited to this; in other embodiments, the mounting bracket 1 can also be made of aluminum alloy, 316 stainless steel, or cast iron, or other metal materials that can transfer heat and meet corrosion resistance and strength requirements. The width of the mounting bracket 1 can be designed to be 12mm to ensure structural strength and connection reliability. However, this application is not limited to this; in other embodiments, the width of the mounting bracket 1 can be 8mm, 10mm, 14mm, 16mm, or 18mm, etc.
[0095] In order to stably install the connecting rod 3 on the measuring cylinder 2 at intervals, refer to Figure 4 , Figure 6 As shown, the connecting rod 3 in this embodiment includes a first end and a second end, and the mounting bracket 1 includes a first mounting bracket 1 and a second mounting bracket 1. The first end and the second end are respectively fixedly mounted on the measuring cylinder 2 through the first mounting bracket 1 and the second mounting bracket 1.
[0096] Preferably, in order to improve the connection reliability between the first mounting part 12 and the measuring cylinder 2, and between the second mounting part 13 and the connecting rod 3, refer to Figure 7 As shown, in this embodiment, the first mounting part 12 is fixedly mounted on the measuring cylinder 2 by the first clamp 5, and the second mounting part 13 is fixedly mounted on the connecting rod 3 by the second clamp 6. The diameter of the first clamp 5 is larger than the diameter of the second clamp 6.
[0097] Preferably, refer to Figure 7As shown, the first mounting part 12 in this embodiment includes a first flat plate that abuts against the outer wall of the measuring cylinder 2. This design allows for line contact between the mounting bracket 1 and the measuring cylinder 2, minimizing the heat transfer area and ensuring that the measuring cylinder 2 transfers minimal heat to the mounting bracket 1 per unit time. The second mounting part 13 in this embodiment includes a second flat plate that abuts against the outer wall of the connecting rod 3. This design also allows for line contact between the mounting bracket 1 and the connecting rod 3, minimizing the heat transfer area and ensuring that the mounting bracket 1 transfers minimal heat to the connecting rod 3 per unit time. During heat transfer, sufficient time is allowed for the heat received by the connecting rod 3 to be dissipated through air convection to within the rated operating temperature of the precision sensing unit inside the connecting rod 3, preventing excessively high local temperatures that could affect product performance.
[0098] To reduce the impact of thermal radiation, refer to Figure 7 As shown, in this embodiment, the gap L3 between the measuring cylinder 2 and the connecting rod 3 can be 8mm. Of course, this application is not limited to this; in other embodiments, the gap between the measuring cylinder 2 and the connecting rod 3 can be 4mm, 6mm, 10mm, or 12mm.
[0099] Optional, refer to Figure 4 , Figure 6 As shown, in this embodiment, the junction box 4 is higher than the upper end of the measuring cylinder 2. By suspending the junction box 4, the influence of heat radiation is reduced, and the heat transferred to the junction box 4 is reduced by the flow of air carrying away the heat.
[0100] By using the mounting bracket 1 in this embodiment to set the distance between the connecting rod 3 and the measuring cylinder 2 to 8mm, the heat barrier efficiency can be improved by 84%. Figure 8 , Figure 9 As shown, the temperature at the end of the first mounting part 12 furthest from the second mounting part 13 is 349.6℃, and the temperature at the end of the second mounting part 13 furthest from the first mounting part 12 is 177.9℃. Gradual cooling is achieved at the mounting bracket 1 so that after the heat is conducted from the mounting bracket 1 to the connecting rod 3, the heat is conducted upward along the length of the connecting rod 3 until it reaches the upper end of the connecting rod 3. The temperature at the upper end of the connecting rod 3 can be less than or equal to 120℃, thereby meeting the rated operating temperature requirements of the precision sensing unit inside the connecting rod 3.
[0101] Meanwhile, since the structure of heat insulation material is not set, the weight of the mounting bracket 1 is reduced, thereby reducing the production cost, transportation cost and installation cost of the mounting bracket 1.
[0102] It should be noted that the structures and working principles of the measuring cylinder 2, wire box 4, first clamp 5, second clamp 6, etc., which are not described in detail in this application, can all adopt existing solutions in the prior art, which can be understood and accepted by those skilled in the art, and therefore will not be described in detail.
[0103] In the description of the embodiments of this utility model, it should be understood that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the product is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
