Description

Technical Field

[0001] This utility model belongs to the field of marine liquid level switch installation technology, specifically relating to a height-adjustable liquid level switch bracket. Background Technology

[0002] In ship design, level switches are mainly installed in various important compartments throughout the ship, such as the engine room, oil tanks, freshwater tanks, and empty compartments. Level switch alarm devices, through real-time monitoring, precise early warning, and system linkage, become the "nerve endings" of ship safety design; therefore, the design and placement of level switch brackets are crucial. Existing level switches are available in two types: top-mounted and side-mounted. Side-mounted switches are primarily used on the sidewalls of oil tanks, with the alarm point height calculated based on the tank capacity table to determine the installation height. Top-mounted level switches are generally used in empty compartments or areas with sewage wells. Regarding the setting of the alarm point height, each shipowner will question the rationality of the installation height of the level switch bracket based on their own experience and propose modifications, resulting in repeated and extensive rework. The ideal height value should consider various possibilities during ship navigation, such as leaking equipment, seepage from pipe flanges, and water ingress into the structure, and calculate the time required for water to reach a certain height. However, this is a probabilistic calculation problem with many unknown and uncontrollable factors, making accurate calculation and evaluation impossible. To address this challenging issue, this application presents a height-adjustable bracket for practical installation of level switches in various complex scenarios. Summary of the Invention

[0031] Example 1

[0032] like Figure 1 As shown, a height-adjustable liquid level switch bracket is provided, including a fixed bracket 100, an adjusting bracket 200, a connector 300, and a mounting plate 400;

[0033] In the picture:

[0034] The mounting bracket 100 has four mounting holes 101 of different heights along its vertical length;

[0035] The adjustment frame 200 includes a base frame 201, and the base frame 201 has two mounting holes 203 along its vertical edge;

[0036] Both the fixing hole 101 and the assembly hole 203 are threaded holes;

[0037] The connector 300 includes a connecting bolt 301 and a connecting nut 302;

[0038] The mounting plate 400 is fixed to one side of the adjusting frame 200, and the liquid level switch is connected to the mounting plate 400 by fixing bolts.

[0039] In this embodiment, the operation of installing the liquid level switch is as follows:

[0040] Depending on the application scenario, the fixing frame 100 can be designed in various shapes. The conventional shape is rectangular. When the plane shown by the dotted line in the figure is used as the welding surface, and the fixing frame 100 is welded to the side wall of the cabin and there is a structural ball flat steel obstructing it, an avoidance notch 102 can be designed on one side of the fixing frame 100.

[0041] The base frame 201 and the mounting plate 400 are integrally formed or welded together;

[0042] Align the two mounting holes 203 on the base frame 201 with any two adjacent fixing holes 101 on the fixing frame 100 coaxially; screw the connecting bolt 301 through the coaxially matched fixing holes 101 and mounting holes 203, and then screw the connecting nut 302 onto the connecting bolt 301 to complete the fixed connection between the adjusting frame 200 and the fixing frame 100.

[0043] As described above, when the assembly hole 203 is aligned with the fixing holes 101 at different heights, the adjusting bracket 200, the mounting plate 400 and the liquid level switch can be installed at different heights.

[0044] Example 2

[0045] For the height-adjustable liquid level switch bracket provided in Embodiment 1 above, the installation height of the liquid level switch can be effectively adjusted by cooperating with the mounting holes 203 and fixing holes 101 at different heights. This installation is suitable for the initial installation of the liquid level switch. However, for adjusting the height of the liquid level switch after installation, both connecting parts 300 need to be completely disassembled before readjustment and installation. The two disassembled connecting parts 300 include two connecting bolts 301 and two connecting nuts 302. Since there are many connecting bolts 301 and connecting nuts 302, the operator cannot hold them in one hand. As a result, the connecting bolts 301 and connecting nuts 302 are usually left lying around, which can easily lead to the loss of these connecting accessories, thus affecting the rapid adjustment of the liquid level switch installation height. To address this problem, in this embodiment:

[0046] like Figure 2 , Figure 3 and Figure 4 As shown, a height-adjustable liquid level switch bracket is provided, including a fixed bracket 100, an adjusting bracket 200, a connector 300, and a mounting plate 400;

[0047] In the picture:

[0048] The mounting bracket 100 has four mounting holes 101 of different heights along its vertical length;

[0049] The adjusting frame 200 includes a base frame 201 and a slide 202. The slide 202 has a sliding groove 205 (making the slide 202 form an n-shaped structure). One side of the base frame 201 has a protrusion 204 that cooperates with the sliding groove 205 (so that the base frame 201 and the slide 202 can be raised and lowered relative to each other vertically). Both the base frame 201 and the slide 202 have assembly holes 203.

[0050] Both the fixing hole 101 and the assembly hole 203 are threaded holes;

[0051] The connector 300 includes a connecting bolt 301 and a connecting nut 302;

[0052] The mounting plate 400 is fixed to one side of the adjusting frame 200, and the liquid level switch is connected to the mounting plate 400 by fixing bolts.

[0053] In this embodiment, the operation of installing the liquid level switch is as follows:

[0054] The mounting bracket 100 is welded and fixed inside the cabin;

[0055] The base frame 201 and the mounting plate 400 are integrally formed or welded together;

[0056] Align the two mounting holes 203 on the base frame 201 and the slide 202 with any two fixing holes 101 on the fixed frame 100 coaxially; screw the connecting bolt 301 through the coaxially matched fixing holes 101 and mounting holes 203, and then screw the connecting nut 302 onto the connecting bolt 301 to complete the fixed connection between the adjusting frame 200 and the fixed frame 100.

[0057] Continue to combine Figure 3 As shown, in this embodiment, the operation of adjusting the installation height of the liquid level switch is as follows:

[0058] The connection between the slide 202 and the fixed frame 100 is released by rotating the connecting nut 302 and the connecting bolt 301; the positioning height of the slide 202 is readjusted by raising and lowering the slide 202, and the mounting hole 203 on the slide 202 is aligned coaxially with one of the fixing holes 101 on the fixed frame 100. After alignment, the slide 202 and the fixed frame 100 are re-fixed using the connecting nut 302.

[0059] The connection between the base frame 201 and the fixed frame 100 is released by rotating the connecting nut 302 and the connecting bolt 301; the positioning height of the base frame 201 is readjusted by lifting and moving the base frame 201, and the mounting hole 203 on the base frame 201 is aligned coaxially with one of the fixing holes 101 on the fixed frame 100. After alignment, the base frame 201 and the fixed frame 100 are re-fixed using the connecting nut 302.

[0060] In this embodiment, the relative lifting and lowering of the slide 202 of the base frame 201 can be adjusted independently, that is, a set of connecting bolts 301 and connecting nuts 302 can be removed each time. Therefore, during the entire lifting and adjusting process, the number of connecting bolts 301 and connecting nuts 302 removed at the same time is small. The operator can place the connecting bolts 301 and connecting nuts 302 in their hand or by their side, avoiding the loss of the connecting bolts 301 and connecting nuts 302, and facilitating the rapid adjustment of the liquid level switch installation height.

[0061] Furthermore, in this embodiment, to avoid the sharp corners of the overall support structure from accidentally injuring the operator, it is preferable that a transition slope 103 is provided at the bottom end of both the fixed frame 100 and the base frame 201.

[0062] Furthermore, in this embodiment, considering that the liquid level switch needs to be pulled out upwards during fault repair, but some areas cannot be pulled out upwards due to structural obstruction at the top, it is preferable to provide an opening groove 401 on the mounting plate 400 to cooperate with the liquid level switch. In the figure of this embodiment, the opening groove 401 is presented as a crescent-shaped notch groove, so as to facilitate the liquid level switch to be moved out of the opening groove 401.

[0063] Example 3

[0064] This embodiment is based on Embodiment 2.

[0065] In the second embodiment described above, the relative lifting and lowering of the base frame 201 and the slide 202 makes the height adjustment of the liquid level switch after installation more convenient and quick. However, in this structure, the overall weight of the base frame 201, the mounting plate 400, and the liquid level switch is concentrated on a set of connecting parts 300 (a set of connecting bolts 301 and connecting nuts 302). The slide 202 and its mating connecting parts 300 only serve a guiding function, affecting the overall structural support strength. To address this issue, in this embodiment:

[0066] like Figure 2 As shown, a height-adjustable liquid level switch bracket is provided, including a fixed frame 100, an adjusting frame 200, a connector 300, and a mounting plate 400. The fixed frame 100, connector 300, and mounting plate 400 are the same as in Embodiment 2, but the adjusting frame 200 is further optimized in this embodiment.

[0067] Continue to refer to Figure 4 , Figure 5 and Figure 6 As shown:

[0068] The adjusting frame 200 includes a base frame 201 and a slide 202. The slide 202 has a sliding groove 205 (making the slide 202 form an n-shaped structure). One side of the base frame 201 has a protrusion 204 that cooperates with the sliding groove 205 (so that the base frame 201 and the slide 202 can be raised and lowered relative to each other vertically). Both the base frame 201 and the slide 202 have assembly holes 203.

[0069] A slot 206 is provided on one side of the protrusion 204;

[0070] The slide 202 has an installation groove, in which a movable insert 207 and a rotatable eccentric wheel 208 are provided. The insert 207 has a through hole 209 that accommodates and engages with the eccentric wheel 208. The eccentric wheel 208 is driven to rotate by a damping shaft 210, which extends from the top of the slide 202.

[0071] In this embodiment, the operation of adjusting the installation height of the liquid level switch is as follows:

[0072] Rotating the damping shaft 210 drives the eccentric wheel 208 from Figure 6 Rotate 180° as shown to remove one end of the insert 207 from the slot 206, thereby unlocking the carriage 202 from the base frame 201;

[0073] The connection between the slide 202 and the fixed frame 100 is released by rotating the connecting nut 302 and the connecting bolt 301; the positioning height of the slide 202 is readjusted by raising and lowering the slide 202, and the mounting hole 203 on the slide 202 is aligned coaxially with one of the fixing holes 101 on the fixed frame 100. After alignment, the slide 202 and the fixed frame 100 are re-fixed using the connecting nut 302.

[0074] The connection between the base frame 201 and the fixed frame 100 is released by rotating the connecting nut 302 and the connecting bolt 301; the positioning height of the base frame 201 is readjusted by lifting and moving the base frame 201, and the mounting hole 203 on the base frame 201 is aligned coaxially with one of the fixing holes 101 on the fixed frame 100. After alignment, the base frame 201 and the fixed frame 100 are re-fixed using the connecting nut 302.

[0075] Rotating the damping shaft 210 drives the eccentric wheel 208 to rotate 180° and return to its original position. Figure 6 In the state shown, one end of the insert 207 is inserted into the slot 206, thereby connecting the carriage 202 and the base frame 201.

[0076] As described above, the damping shaft 210 ensures that the eccentric wheel 208 will not rotate erroneously without external force, thereby ensuring that the insert block 207 can effectively connect the carriage 202 and the base frame 201.

[0077] In this embodiment, the rotation of the eccentric wheel 208 drives the insertion block 207 to move: when the insertion block 207 disengages from the slot 206, it facilitates the independent lifting and lowering of the carriage 202 and the base frame 201, so as to facilitate the adjustment of the liquid level switch installation height; when the insertion block 207 is inserted into the slot 206, it connects the carriage 202 and the base frame 201, ensuring that both sets of connecting parts 300 (two sets of connecting bolts 301 and connecting nuts 302) and the overall adjustment frame 200 can support the mounting plate 400 and the liquid level switch, thereby improving the structural support strength of the overall bracket.

[0078] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
