Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, and in particular to a mounting bracket for an ultrasonic liquid level switch. Background Technology

[0002] The factory uses float switches to control the start and stop of the sewage pumps to achieve liquid level control. Since most of the control circuits use 220V voltage, each action of the float switch will generate sparks on the contacts, causing significant damage to the contacts and reducing their service life. There is also a risk of leakage. Moreover, the sewage pump pit is often dirty, and debris accumulates at the bottom, causing the float switch to fail to drop. This results in the sewage pump motor running for a long time, causing the liquid level to drop, which can easily burn out the motor and pump body.

[0003] Currently, to address the aforementioned issues, the factory purchases and uses non-contact ultrasonic level switches, such as the Siemens Pointek ULS 200 level gauge, which can be directly connected to the control circuit for non-contact measurement of liquids, slurries, and other media. However, there is a lack of dedicated mounting structures for installing and securing these non-contact ultrasonic level switches. Therefore, a mounting bracket for ultrasonic level switches is designed. Utility Model Content

[0004] The purpose of this invention is to provide a mounting bracket for an ultrasonic level switch to solve the problems existing in the prior art.

[0005] This utility model is implemented by the following technical solution: an ultrasonic liquid level switch mounting bracket, which includes a fixing frame, a first bracket and a second bracket; The fixing frame has a Z-shaped structure, and a number of sequentially connected threaded holes are vertically through the middle of the fixing frame; The first bracket includes a limiting plate, a threaded rod, a first support rod, a second support rod, a first fixing ring, and a limiting bolt; The threaded rod is threaded into the threaded hole of the fixed frame. The end of the threaded rod that passes through the fixed frame is fixedly connected to the limiting plate. The end of the threaded rod that passes out of the fixed frame is fixedly connected to one end of the first support rod. The other end of the first support rod is fixedly connected to one end of the second support rod. The other end of the second support rod is fixedly connected to the side of the first fixed ring. The center line of the first fixed ring is arranged perpendicular to the second support rod. Multiple limiting bolts are evenly distributed and threaded along the circumferential direction on the side of the first fixed ring. The second bracket includes a third support rod and a second fixing ring. One end of the third support rod passes through the first fixing ring and is fixed by the limiting bolt. The other end of the third support rod is fixedly connected to the side of the second fixing ring. The center line of the second fixing ring is arranged perpendicular to the third support rod.

[0006] Preferably, adjacent threaded holes are connected by a channel, the diameter of which is greater than or equal to the diameter of the first support rod.

[0007] Preferably, the threaded rod, the first support rod, the second support rod, and the third support rod all adopt a hollow rod structure.

[0008] Advantages of this invention: This invention adjusts the installation height of the first bracket by installing the threaded rod of the first bracket into threaded holes at different heights on the fixed frame; the position of the third support rod is adjusted by loosening or tightening the limiting bolt of the first bracket to make it open or close the third support rod of the second bracket, thereby adjusting the distance between the second fixing ring and the first bracket.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figures 1-3 As shown, an ultrasonic level switch mounting bracket includes a fixing frame 1, a first bracket 2, and a second bracket 3. The fixing frame 1 has a U-shaped structure. The two sides of the fixing frame 1 are fixed to the inner wall of the sewage pump pit by bolts. Several threaded holes 1.1 are vertically connected in the middle of the fixing frame 1. The threaded holes 1.1 are used to install the first bracket 2. The installation height of the first bracket 2 can be adjusted by installing the first bracket 2 in the threaded holes 1.1 at different heights. Adjacent threaded holes 1.1 are connected by channels 1.2 to facilitate the vertical movement of the first support rod 2.3 of the first bracket 2. The first bracket 2 includes a limiting plate 2.1, a threaded rod 2.2, a first support rod 2.3, a second support rod 2.4, a first fixing ring 2.5, and a limiting bolt 2.6; the threaded rod 2.2, the first support rod 2.3, and the second support rod 2.4 all adopt a hollow rod structure, which can reduce weight and avoid instability due to excessive weight of the mounting bracket; The threaded rod 2.2 is threaded into the threaded hole 1.1 of the fixing frame 1. The end of the threaded rod 2.2 that passes through the fixing frame 1 is fixedly connected to the limiting plate 2.1. The limiting plate 2.1 prevents the first bracket 2 from coming out of the threaded hole 1.1. The end of the threaded rod 2.2 that passes out of the fixing frame 1 is fixedly connected to one end of the first support rod 2.3. The diameter of the first support rod 2.3 is less than or equal to the diameter of the channel 1.2. The other end of the first support rod 2.3 is fixedly connected to one end of the second support rod 2.4. The other end of the second support rod 2.4 is fixedly connected to the side of the first fixing ring 2.5. The centerline of the first fixing ring 2.5 is arranged perpendicularly to the second support rod 2.4. Multiple limiting bolts 2.6 are evenly distributed and threaded along the side of the first fixing ring 2.5. The multiple limiting bolts 2.6 facilitate the installation and fixing of the second bracket 3. When the first bracket 2 is screwed to move the threaded rod 2.2 inward to the fixing frame 1, the fixing frame 1 with its Z-shaped structure can provide space for the threaded rod 2.2 to disengage from the threaded hole 1.1. The diameter of the first support rod 2.3 is designed to be less than or equal to the diameter of the channel 1.2, so that the first support rod 2.3 can vertically pass through the channel 1.2 and enter the target threaded hole 1.1. The second bracket 3 includes a third support rod 3.1 and a second fixing ring 3.2. The third support rod 3.1 has a hollow rod structure. One end of the third support rod 3.1 passes through the first fixing ring 2.5 and is fixed by a limiting bolt 2.6. The other end of the third support rod 3.1 is fixedly connected to the side of the second fixing ring 3.2. The center line of the second fixing ring 3.2 is arranged perpendicular to the third support rod 3.1. The second fixing ring 3.2 is used to fix the ultrasonic liquid level switch 4. The position of the third support rod 3.1 is adjusted by the first fixing ring 2.5 and the limiting bolt 2.6, thereby adjusting the distance between the second fixing ring 3.2 and the first bracket 2, and ensuring that the second fixing ring 3.2 faces the liquid surface, which facilitates the installation of the ultrasonic liquid level switch 4.

[0015] Installation and Usage Instructions: The two sides of the mounting bracket 1 are fixed to the inner wall of the sewage pump pit with bolts. Twist the first bracket 2 in the forward direction to move the threaded rod 2.2 inward to the inside of the mounting bracket 1 until the threaded rod 2.2 disengages from the threaded hole 1.1. Then, let the first support rod 2.3 pass vertically through the channel 1.2 to the target threaded hole 1.1. Pull the first bracket 2 outward to the outside of the mounting bracket 1 so that the threaded rod 2.2 is aligned with the target threaded hole 1.1. Then, twist the first bracket 2 in the reverse direction to make the threaded rod 2.2 fully enter the target threaded hole 1.1. Adjust the first bracket 2 to the target installation height. Tighten the limiting bolt 2.6 to loosen the third support rod 3.1. Adjust the position of the third support rod 3.1 so that the second fixing ring 3.2 is at the target distance from the first bracket 2. Rotate the third support rod 3.1 so that the second fixing ring 3.2 faces the liquid surface. An ultrasonic liquid level switch 4 facing the liquid surface is fixed inside the second fixing ring 3.2.
