Description

Technical Field

[0001] The utility model relates to the technical field of alarm devices, in particular to a reagent barrel liquid level alarm device. Background Art

[0002] During the continuous experiment, the total amount of reagent in the reagent barrel needs to be monitored in real time to avoid affecting the stable progress of the continuous experiment. In the prior art, a liquid level alarm is used to detect and alarm the total amount of reagent in the reagent barrel.

[0003] The vertical pole and the liquid level sensor set at one end are inserted into the reagent barrel, and then the liquid level alarm and the reagent barrel are fixed by the mounting flange. However, the mounting flange is fixed on the outer wall of the vertical pole, so a group of liquid level alarms can only monitor and alarm the liquid level height of one reagent, which has great limitations.

[0004] The main reason for the above problems is that the mounting flange and the vertical pole are in a fixed connection state. Therefore, the placement position of the liquid level sensor inserted into the reagent barrel is single. When it comes to reagent barrels of different sizes, the liquid level height that the liquid level sensor can monitor cannot meet the monitoring requirements of the liquid levels of reagent barrels of different sizes. In addition, there is no device in the prior art for changing the connection position between the mounting flange and the vertical pole, which limits the use range of the liquid level alarm. To address the above problems, we propose a reagent barrel liquid level alarm device. Utility Model Content

[0010] Preferably, a limiting rod is fixedly connected between the two groups of fixing rings, and one end of the mounting flange is slidably disposed on an outer wall of the limiting rod.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are 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.

[0026] The embodiment of the present application solves the problem that the mounting flange is fixed on the outer wall of the vertical pole, so a group of liquid level alarms can only monitor and alarm the liquid level height of one reagent, which has great limitations, by providing an alarm device. The liquid level alarm can monitor and alarm the liquid level height inside reagent barrels of different sizes.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The utility model embodiment discloses a reagent barrel liquid level alarm device.

[0029] According to the attached Figure 1-5As shown, it includes a vertical pole 1 inserted into the reagent barrel, a liquid level sensor 101 fixedly connected to the bottom end face of the vertical pole 1, an alarm box 102 connected to the top end face of the vertical pole 1, and a mounting flange 2 for installation between the vertical pole 1 and the reagent barrel. A buzzer 103 is arranged inside the alarm box 102. The vertical pole 1, the liquid level sensor 101, the alarm box 102, the buzzer 103 and the mounting flange 2 constitute a liquid level alarm model HT-C01. When it is used, it is first inserted into the reagent barrel so that the liquid level sensor 101 is located inside the reagent barrel, and then the alarm box 102 is installed by the installation method. Lan 2 and components such as the screw rod fix the liquid level alarm to the reagent barrel. When the reagent liquid level inside the reagent barrel drops to the height of the liquid level sensor 101, the buzzer 103 sounds an alarm to alert the staff to avoid too little reagent inside the reagent barrel, which would affect the continuous progress of the experiment. In addition, when the detected liquid level does not reach the alarm position, the alarm box 102 and the buzzer 103 are in normal working condition, and the buzzer 103 does not sound. When the detected liquid level reaches the alarm position of the liquid level sensor 101, the liquid level alarm is in the liquid level alarm state, and the buzzer 103 sounds an alarm.

[0030] The outer wall of the vertical pole 1 is provided with an adjusting mechanism 3 for adjusting the setting position of the mounting flange 2. According to the demand, the alarm operation is performed for the liquid levels at different heights inside the reagent barrel, that is, the position of the mounting flange 2 on the outer wall of the vertical pole 1 is adjusted, and the length of the vertical pole 1 inserted inside the reagent barrel is controlled, so as to control the sensing position of the liquid level sensor 101 on the bottom end face of the vertical pole 1. The adjusting mechanism 3 includes: a fixing ring 301 fixedly connected to the outer wall of the vertical pole 1, a threaded rod 302 rotatably set between the two groups of fixing rings 301, and the mounting flange 2 is threadedly sleeved on the outer wall of the threaded rod 302, a limit rod 303 is fixedly connected between the two groups of fixing rings 301, one end of the mounting flange 2 is slidably set on the outer wall of the limit rod 303, and the outer wall of the vertical pole 1 is fixedly connected with a scale mark 306, and the scale mark 306 is used to locate the setting position of the mounting flange 2.

[0031] The locking assembly is used to lock the connection position between the mounting flange 2 and the vertical pole 1. The locking assembly includes a threaded ring 304, which is threadedly sleeved on the outer wall of one end of the threaded rod 302 extending to the upper part of the fixing ring 301. The threaded groove 305 is opened on the top end surface of a group of fixing rings 301. The connection position between the mounting flange 2 and the vertical pole 1 is locked through the threaded connection between the threaded ring 304 and the threaded groove 305. The threaded teeth opened on the outer wall of the threaded ring 304 are threadedly connected with the threaded teeth opened on the inner wall of the threaded groove 305.

[0032] The reagent barrel liquid level alarm device adjusts the installation position of the mounting flange 2 relative to the vertical pole 1 by arranging an adjustment mechanism 3 on the outer wall of the vertical pole 1, thereby controlling the length of the vertical pole 1 inserted into the reagent barrel, so that the liquid level sensor 101 arranged on the bottom end face of the vertical pole 1 can sense and alarm the different heights of the liquid levels of the reagent in the reagent barrel. A set of liquid level alarms can meet the alarm requirements of different liquid levels in the reagent barrel, and has good practicality.
