Description

Technical Field

[0001] This utility model relates to the field of sensor bracket technology, and in particular to a liquid level sensor bracket based on a flat-top pool. Background Technology

[0002] In closed leachate storage tanks, accurately measuring the liquid level is a crucial parameter monitoring task. Currently, construction companies typically use methods such as... Figure 1 The sensor bracket shown is used to fix the liquid level sensor, but the following problems exist when using the existing bracket: (1) The bracket lacks depth adjustment function. In particular, since the leachate treatment station has a variety of tanks and the top layer thickness of each tank is different (the thinnest and the thickest may differ by 20 cm), when installed on a thicker tank cover, the sensor probe may cause echo interference due to excessive retraction into the tank opening; (2) Improper installation will cause the sensor to be unable to maintain a horizontal state, which will affect the accuracy of liquid level measurement; (3) It is difficult to achieve effective sealing during installation, which may cause odor to escape or make it difficult to disassemble the sensor for cleaning and maintenance; (4) The sensor connection cable is easily damaged and broken due to excessive installation tension. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. The present invention provides a liquid level sensor bracket based on the flat top of the pool. When replacing the liquid level sensor between pools, the insertion depth of the sensor can be adjusted and the sensor can be kept horizontal. At the same time, it must also meet certain airtightness and ensure easy disassembly.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a liquid level sensor bracket based on a flat-top pool, which includes: a mounting frame, the mounting frame being mounted on the pool top;

[0005] A horizontal balance block, comprising a rotating rod and a counterweight, wherein the rotating rod is arranged parallel to the pool surface and rotatably disposed within the mounting frame, and the upper end of the counterweight is connected to the rotating rod;

[0006] An adjusting rod passes through the counterweight and is perpendicular to the pool surface. The adjusting rod is threadedly connected to the counterweight, and a liquid level sensor is installed at the lower end of the adjusting rod.

[0007] The specific technical effects are as follows: By setting a rotating rod that is rotatably connected to the mounting frame, and setting a counterweight on the rotating rod, the principle of gravity is utilized to ensure that even if the mounting frame is installed on an inclined pool top, the horizontal counterweight remains horizontal, meaning that the adjusting rod and the liquid level sensor are always perpendicular to the pool surface. The adjusting rod is threadedly connected to the counterweight, and the position of the adjusting rod is changed by rotating it, thereby adjusting the insertion depth of the liquid level sensor. Using this bracket facilitates the height adjustment, disassembly, and cleaning of the liquid level sensor, avoids damage from tension on the connecting cable, and ensures that the sensor is horizontal after installation.

[0008] Furthermore, the inner wall of the mounting bracket is provided with two mounting grooves symmetrically arranged along the center, and the two ends of the rotating rod are rotatably disposed in one of the mounting grooves.

[0009] The specific technical effects are as follows: the mounting slot provides a stable rotation support point for the rotating rod, so that even if the mounting bracket is installed on the inclined top of the pool, the rotating rod can rotate relative to the mounting bracket, thereby adjusting the horizontal state of the horizontal balance block; the design of the mounting slot makes the installation and disassembly of the rotating rod simple and convenient. When maintenance, cleaning or disassembly of this bracket to move to other storage pools is required, the horizontal balance block can be removed from the mounting slot, and then the liquid level sensor can be lifted directly.

[0010] Furthermore, the counterweight has a hemispherical structure, and an adjustment hole is provided on the counterweight. The adjustment hole extends through the counterweight from the center of the hemispherical structure in a direction perpendicular to the pool surface, and the adjustment rod is installed in the adjustment hole.

[0011] The specific technical effects are as follows: the hemispherical counterweight has a low center of gravity and is evenly distributed, making it easier for the entire horizontal counterweight to reach a stable state during rotation and adjustment. It can automatically adjust to a horizontal state using the principle of gravity, thereby ensuring that the adjusting rod and the liquid level sensor are always perpendicular to the pool surface. The design of the adjusting hole can precisely adjust the position of the adjusting rod, thereby conveniently changing the insertion depth of the liquid level sensor to meet the usage requirements of different pool top thicknesses.

[0012] Furthermore, the inner wall of the adjusting hole is provided with an internal thread, and the outer wall of the adjusting rod is provided with an external thread that matches the internal thread.

[0013] Furthermore, the adjusting rod has an axial through hole, and the liquid level sensor is threadedly connected to the lower end of the through hole.

[0014] Furthermore, the upper end of the adjusting rod has a through hole for the cable of the liquid level sensor to pass through, and the through hole is connected to the through hole.

[0015] The specific technical effect is that by setting a wire hole for the liquid level sensor cable to pass through, the liquid level sensor cable is always in a free state, avoiding the cable from being taut and damaged.

[0016] Furthermore, a handle is provided at the upper end of the adjusting rod.

[0017] The specific technical effect is that the handle facilitates the rotation of the adjustment rod.

[0018] Furthermore, before the mounting frame is erected on the top of the pool, a rubber pad is placed between the mounting frame and the top of the pool.

[0019] The specific technical effects are: there is usually an odor extraction pipe in the pool to maintain a slight negative pressure, and the use of rubber gaskets for sealing can effectively prevent odor leakage.

[0020] Furthermore, after the mounting frame is erected on the top of the pool, a sealing cover is provided on the outside of the mounting frame.

[0021] The specific technical effects are: by setting up a sealing cover, the sealing is further guaranteed, and the cable and the entire bracket can be protected, as well as rainwater can be prevented from entering the mounting bracket and damaging the sensor when it is installed outdoors.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] (1) This utility model sets a rotating rod and a mounting frame for rotational connection, and sets a counterweight on the rotating rod. By utilizing the principle of gravity, the horizontal counterweight can remain horizontal even if the mounting frame is installed on an inclined pool top, that is, the adjusting rod and the liquid level sensor are always perpendicular to the pool surface.

[0024] (2) This utility model sets an adjustment rod and a counterweight connected by a thread. The position of the adjustment rod can be changed by rotating the adjustment rod, thereby adjusting the insertion depth of the liquid level sensor. Using this bracket facilitates the height adjustment and disassembly and cleaning of the liquid level sensor, avoids the connection cable from being stretched and damaged, and ensures that the sensor is level after installation.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figures 2 to 3The diagram shows a preferred embodiment of this utility model. This embodiment provides a support for a liquid level sensor 5 mounted on a flat-topped pool 4. The support includes a mounting frame 1, a horizontal balance block 2, and an adjusting rod 3. The mounting frame 1 is mounted on the horizontally positioned pool 4. The horizontal balance block 2 includes a rotating rod 201 and a counterweight 202. The rotating rod 201 is parallel to the pool surface and rotatably mounted within the mounting frame 1. The upper end of the counterweight 202 is connected to the rotating rod 201. The adjusting rod 3 passes through the counterweight 202 and is perpendicular to the pool surface. The adjusting rod 3 is threadedly connected to the counterweight 202. The liquid level sensor 5 is mounted on the lower end of the adjusting rod 3. Thus, the adjusting rod 3 is threadedly connected to the counterweight 202. By rotating the adjusting rod 3, its position can be changed, thereby adjusting the insertion depth of the liquid level sensor 5. Using this support facilitates height adjustment, disassembly, and cleaning of the liquid level sensor 5, avoids damage to the connecting cable 8 due to tension, and ensures the sensor is level after installation.

[0035] In this embodiment, two symmetrical mounting slots 101 are provided on the inner wall of the mounting frame 1, and the two ends of the rotating rod 201 are rotatably disposed in one of the mounting slots 101. Thus, the mounting slots 101 provide a stable rotation support point for the rotating rod 201. Even if the mounting frame 1 is installed on the inclined pool top 4, the rotating rod 201 can rotate relative to the mounting frame 1, thereby adjusting the horizontal state of the horizontal balance block 2. The design of the mounting slots 101 makes the installation and disassembly of the rotating rod 201 simple and convenient. When maintenance, cleaning, or disassembly of this bracket to move to other storage pools is required, the horizontal balance block 2 can be removed from the mounting slots 101, and then the liquid level sensor 5 can be directly lifted.

[0036] In this embodiment, the counterweight 202 has a hemispherical structure, and an adjustment hole 203 is provided on the counterweight 202. The adjustment hole 203 extends through the counterweight 202 from the center of the hemispherical structure in a direction perpendicular to the pool surface, and the adjustment rod 3 is installed in the adjustment hole 203. Therefore, the hemispherical counterweight 202, due to its low center of gravity and uniform distribution, makes it easier for the entire horizontal counterweight 2 to reach a stable state during rotational adjustment. It can automatically adjust to a horizontal state using the principle of gravity, thereby ensuring that the adjustment rod 3 and the liquid level sensor 5 are always perpendicular to the pool surface. The design of the adjustment hole 203 allows for precise adjustment of the position of the adjustment rod 3, thereby conveniently changing the insertion depth of the liquid level sensor 5 to meet the usage requirements of different pool top thicknesses 4.

[0037] In this embodiment, the inner wall of the adjusting hole 203 is provided with an internal thread, and the outer wall of the adjusting rod 3 is provided with an external thread that matches the internal thread.

[0038] In this embodiment, a through hole 301 is provided in the adjusting rod 3 along the axial direction, and the liquid level sensor 5 is threadedly connected to the lower end of the through hole 301.

[0039] In this embodiment, the upper end of the adjusting rod 3 is provided with a wire hole 302 for the cable 8 of the liquid level sensor 5 to pass through, and the wire hole 302 is connected to the through hole 301.

[0040] Therefore, by providing a wire hole 302 for the cable 8 of the liquid level sensor 5 to pass through, the cable 8 of the liquid level sensor 5 is always in a free state, preventing the cable 8 from being taut and damaged.

[0041] In this embodiment, a handle 10 is provided at the upper end of the adjusting rod 3.

[0042] Therefore, by setting handle 10, it is easy to rotate the adjusting rod 3.

[0043] In this embodiment, a rubber pad 6 is placed between the mounting frame 1 and the pool top 4 before the mounting frame 1 is erected on the pool top 4.

[0044] Therefore, the pool is generally equipped with an odor extraction pipe to maintain a slight negative pressure. The use of rubber gasket 6 for sealing can effectively prevent odor leakage and also prevent the mounting bracket 1 from sliding.

[0045] In this embodiment, after the mounting frame 1 is installed on the top of the pool 4, a sealing cover 7 is provided on the outside of the mounting frame 1.

[0046] Therefore, by setting the sealing cover 7, the sealing is further guaranteed, and the cable 8 and the entire bracket can be protected, as well as rainwater can be prevented from entering the mounting bracket 1 and damaging the sensor when it is installed outdoors.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model.

[0048] Based on the above, this utility model also has the following embodiments:

[0049] Example 2:

[0050] like Figure 4 As shown,

[0051] The difference from Embodiment 1 is that the mounting frame 1 is mounted on the inclined pool top 4, and is rotatably connected to the mounting frame 1 by a rotating rod 201. A counterweight 202 is set on the rotating rod 201. Utilizing the principle of gravity, even if the mounting frame 1 is mounted on the inclined pool top 4, the horizontal counterweight 2 can rotate relative to the mounting frame 1, thereby keeping the horizontal counterweight 2 horizontal. That is, the adjusting rod 3 and the liquid level sensor 5 are always perpendicular to the pool surface.

[0052] Exemplary, the steps for manufacturing a liquid level sensor 5 bracket based on a flat-top pool roof 4 according to the present invention are as follows:

[0053] (1) First, measure the diameter of the threaded mounting head of the liquid level sensor 5 to obtain the radius R;

[0054] (2) Make the adjusting rod 3 using a uniform 304 stainless steel tube. The radius of the through hole 301 of the adjusting rod 3 is R, which is used to match the threaded mounting head of the liquid level sensor 5. The outer wall of the adjusting rod 3 is provided with external threads, and the outer diameter of the adjusting rod 3 is 2.2R.

[0055] (3) Make a horizontal balance block 2 using Yunzhi 304 stainless steel (as a counterweight). Drill an adjustment hole 203 at the center of the balance counterweight 202 in a direction perpendicular to the pool surface. The inner wall of the adjustment hole 203 is provided with internal threads. The inner diameter of the adjustment hole 203 is 2.2R. The lower end of the adjustment rod 3 passes through the adjustment hole 203 and is connected to the liquid level sensor 5. The adjustment rod 3 is threadedly connected to the adjustment hole 203.

[0056] (4) Before the mounting frame 1 is installed on the top of the pool 4, a rubber pad 6 is placed between the mounting frame 1 and the top of the pool 4. Then the mounting frame 1 is installed on the rubber pad 6, and the horizontal balance block 2 and the liquid level sensor 5 are placed together above the pool surface. The rotating rod 201 is installed in the mounting groove 101 of the mounting frame 1.

[0057] (5) According to the actual measurement needs, grasp the handle 10 and rotate it to adjust the position of the adjusting rod 3, thereby adjusting the insertion depth of the liquid level sensor 5.

[0058] (6) A sealing cover 7 is installed on the outside of the mounting bracket 1, and the sealing cover 7 is fixed to the mounting bracket 1 by the support screw 9.

[0059] The specific dimensions of the components mentioned above are for illustrative purposes only and need to be determined on-site based on the actual situation.

[0060] Compared with the prior art, the beneficial effects of this utility model are:

[0061] (1) This utility model sets a rotating rod 201 to be rotatably connected to the mounting frame 1, and sets a balance weight 202 on the rotating rod 201. By utilizing the principle of gravity, even if the mounting frame 1 is installed on the inclined pool top 4, the horizontal balance weight 2 can still remain horizontal, that is, the adjusting rod 3 and the liquid level sensor 5 are always perpendicular to the pool surface.

[0062] (2) This utility model sets the adjusting rod 3 to be threadedly connected to the counterweight 202. The position of the adjusting rod 3 can be changed by rotating the adjusting rod 3, thereby adjusting the insertion depth of the liquid level sensor 5. Using this bracket facilitates the height adjustment and disassembly and cleaning of the liquid level sensor 5, avoids the connection cable 8 from being stretched and damaged, and ensures that the sensor is level after installation.

[0063] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
